Explanatory Note

This is the companys annual report on Form 20-F for the year ended December 31, 2016. As the company
disclosed on a Form 6-K furnished on May 17, 2017, the company was previously unable to file this annual report on Form 20-F within the prescribed time period
because the company was carrying out additional procedures in connection with the finalization of its consolidated financial statements and the assessment of its internal control over financial reporting as of and for the year ended
December 31, 2016 related to its association with affiliates of Odebrecht S.A. in certain projects in Peru. Additionally, on January 24, 2017, the Peruvian government terminated the concession of Gasoducto Sur Peruano S.A., a consortium
controlled and operated by Odebrecht affiliates in which the company held a minority investment, due to a failure of the consortium to obtain the required project financing by the stipulated deadline. The termination of the concession, despite the
government compensation contemplated under the concession contract, has had a material impact on the consolidated financial results and backlog of the company, which has been under review due to the complexity in the accounting for the concession
and expected government compensation.

In addition, as the company disclosed on Form 6-Ks furnished on
October 5, 2017 and November 3, 2017, the company and its former auditor determined that the former auditor was not independent of the company with respect to the fiscal year 2016 as a consequence of
non-audit services provided by it to the company beginning in the fourth quarter of fiscal year 2016. The services relate to the companys testing of internal controls in accordance with the
Sarbanes-Oxley Act. As a result, the company and its former auditor mutually agreed on October 4, 2017 to the companys dismissal of the former auditor with respect to the companys consolidated financial statements for the fiscal
year 2016. A shareholders meeting of the company held on November 2, 2017 appointed Moore Stephens SCAI S.A. (Moore Stephens) as the new independent auditor for the fiscal year 2016.

Subsequently, on or about March 23, 2018, the former auditor informed the company that it would not authorize the use of its 2015 audit opinion without
conducting substantial additional procedures, which represented a difference in understanding from what the company had since October 2017 when the company dismissed the former auditor as the companys auditor for the 2016 fiscal year. The
former auditor could not give any assurance as to when it could complete such additional procedures. To avoid further delay in filing this annual report, on April 17, 2018, the Audit and Process Committee of the company appointed Moore Stephens
to re-audit the 2015 fiscal year, and the shareholders meeting of the company held on May 14, 2018 ratified the appointment. The previously issued consolidated financial statements of the company
for the 2015 fiscal year (and the related audit opinion) included in the companys annual report on Form 20-F for the year ended December 31, 2015 should not be relied upon. The restatement of the
2015 fiscal year has resulted in certain significant changes to the companys consolidated financial statements. For more information on the effects of the restatement, see note 2.30 to the companys consolidated financial statements
included in this annual report.

These changes of auditor and the subsequent re-audit and audit of the
companys consolidated financial statements for the fiscal years 2015 and 2016, respectively, caused further delay in the filing of this annual report.

For more information, see Item 5.A. Operating and Financial Review and ProspectsRecent Developments and Item 16.F. Change in
Registrants Certifying Accountant of this annual report.

Compañía Operadora de Gas del Amazonas (COGA), and on June 6, 2017, we sold our interest in GMD S.A. (GMD). On April 11, 2018, we sold our interest in Stracon GyM. For more information, see Item

Financial Information

Our consolidated financial statements included in this annual report have been prepared in soles and in accordance with International Financial
Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB). Our annual consolidated financial statements for the years ended December 31, 2015 and 2016 have been audited by Moore Stephens in
accordance with the standards of the Public Company Accounting Oversight Board (United States). Our annual consoldiated financial statements for the years ended December 31, 2012, 2013 and 2014 have been audited by Gaveglio, Aparicio y
Asociados S.C. de R.L., a member firm of PricewaterhouseCoopers. For more information, see Item 16.F. Change in Registrants Certifying Accountant.

Our consolidated financial statements for the year ended December 31, 2015 included in this annual report have been restated. The
previously issued consolidated financial statements of the company for the 2015 fiscal year (and the related audit opinion) included in the companys annual report on Form 20-F for the year ended
December 31, 2015 should not be relied upon. The restatement of the 2015 fiscal year has resulted in certain significant changes to the companys consolidated financial statements. For more information, see note 2.30 to the companys
consolidated financial statements included in this annual report.

We manage our business in four segments: Engineering and Construction
(E&C); Infrastructure; Real Estate; and Technical Services. For information on our results of operations per our business segments, see note 7 to our audited annual consolidated financial statements.

We have requested that the staff of the U.S. Securities and Exchange Commission (the SEC) grant relief from the financial
statement filing requirements of Rule 3-09 of Regulation S-X pursuant to Section 2430 of the Division of Corporation Finance Financial Reporting Manual, with
respect to our investment in GSP. We have requested this relief because we believe the burden of producing financial statements of GSP as of and for the year ended December 31, 2016 would outweigh their limited utility to the companys
investors. In particular, such financial statements would not provide additional material information to our investors that is not already included in our own consolidated financial statements as of and for the year ended December 31, 2016.
This request for relief is pending.

Non-IFRS Data

In this annual report, we present EBITDA, a non-GAAP financial measure. A non-GAAP financial measure is generally defined as one that purports to measure financial performance, financial position or cash flows but excludes or includes amounts that would not be so adjusted in the most
comparable IFRS measure. We present EBITDA because we believe it provides readers with a supplemental measure of the financial performance of our core operations that facilitates
period-to-period comparisons on a consistent basis. Furthermore, we regularly present EBITDA in our filings with the Lima Stock Exchange in Peru. Our management uses
EBITDA, among other measures, for internal planning and performance measurement purposes. We believe that EBITDA is useful in evaluating our operating performance compared to other companies operating in our sectors because the calculation of EBITDA
generally eliminates the effects of financing and income taxes and the accounting effects of capital spending, which items may vary for different companies for reasons unrelated to overall operating performance. EBITDA should not be construed as an
alternative to net profit or operating profit, as an indicator of operating performance, as an alternative to cash flow provided by operating activities or as a measure of liquidity (in each case, as determined in accordance with IFRS). EBITDA, as
calculated by us, may not be comparable to similarly titled measures reported by other companies. For our definition of EBITDA and a reconciliation of EBITDA to the most directly comparable IFRS financial measure, see Item 3.A. Key
InformationSelected Financial DataNon-GAAP Financial Measure and Reconciliation.

Currency
Translations

currencies other than soles in our consolidated financial statements, see note 2.4 to our audited annual consolidated financial statements.

We have translated some of the soles amounts contained in this annual report into U.S. dollars and some U.S. dollars amounts contained in this
annual report into soles, for convenience purposes only. Unless otherwise indicated or the context otherwise requires, the rate used to translate soles amounts to U.S. dollars and U.S. dollars amounts into soles was S/.3.36 to US$1.00, which was the
exchange rate reported for December 31, 2016 by the Peruvian Superintendency of Banks, Insurance and Private Pension Fund Administrators (Superintendencia de Banca, Seguros y AFPs, or SBS). We present our backlog in U.S. dollars.
For contracts denominated in soles or other local currencies, amounts have been converted into U.S. dollars based on the exchange rate published by the SBS on December 31 of the corresponding year. When we present our ratios of backlog and
revenues in this annual report, we similarly convert our revenues, which are reported in soles, into U.S. dollars based on the exchange rate reported for December 31 of the corresponding year. For conversions of macroeconomic indicators
(particularly in Item 5.D. Operating and Financial Review and ProspectsTrend Information in this annual report), average annual exchange rates for the currencies of each of the countries addressed are used. The Federal Reserve Bank
of New York does not report a noon buying rate for soles. The U.S. dollar equivalent information presented in this annual report is provided solely for convenience of the reader and should not be construed as implying that the soles or other
currency amounts represent, or could have been or could be converted into, U.S. dollars at such rates or at any other rate. See Item 3.A. Key InformationSelected Financial DataExchange Rates for information regarding
historical exchange rates of soles to U.S. dollars.

Rounding

Certain figures included in this annual report have been subject to rounding adjustments. Accordingly, figures shown as totals in certain
tables may not be arithmetic aggregations of the figures that precede them.

Backlog

This annual report includes our backlog for our Engineering and Construction, Infrastructure, Real Estate and Technical Services segments. We
do not include backlog in this annual report in our Infrastructure segment for: (i) our Norvial toll road concession because its revenues from the concession are derived from toll fees charged to vehicles using the highway, and, as a result,
such revenues are dependent on vehicular traffic levels; (ii) our Energy line of business because: (a) its revenues from hydrocarbon extraction services are dependent on the amounts of oil and gas we produce and market prices, which
fluctuate significantly; (b) our revenues from our gas processing plant are dependent on the amount of gas we process and market prices for natural gas liquids, which fluctuate significantly; and (c) our revenues from our fuel storage
terminal operation partially depend on the volume of fuel dispatched; and (iii) COGA, which is not consolidated because it was jointly controlled, and which we sold on April 24, 2017. When we present backlog on a segment basis, we do not
include eliminations that are included in our consolidated backlog. Backlog is not a measure defined by IFRS, and our methodology for determining backlog may not be comparable to the methodology used by other companies in determining their backlog.
Backlog is not audited. For our definition of backlog, see Item 4.B. Information on the CompanyBusiness OverviewBacklog. See also Item 3.D. Key InformationRisk FactorsRisks Related to our CompanyOur
backlog and our ratio of historical backlog to revenues may not be reliable indicators of future revenues or profit.

Reserves Estimates

This annual report
includes our estimates for proved reserves in Blocks I and V, where GMP provides hydrocarbon extraction services to, and Blocks III and IV, where GMP extracts hydrocarbon under license agreements with, Perupetro S.A. (Perupetro). These
reserves estimates were prepared internally by our team of engineers and have not been audited or reviewed by any independent external engineers. For further information on these reserves estimates, see Item 3.D. Key InformationRights
Relating to Our Company  Additional Risks Related to our Infrastructure Business and Item 4.B. Information on the CompanyBusiness OverviewInfrastructurePrincipal Infrastructure Lines of
BusinessEnergyOil and Gas Production.

Market Information

We make estimates in this annual report regarding our competitive position and market share, as well as the market size and expected growth of
the engineering and construction, infrastructure, real estate and technical services industries in Peru and elsewhere in Latin America. We have made these estimates on the basis of our managements knowledge and statistics and other
information, which we believe to be the most recently available as of the date of this annual report, from government agencies, industry professional organizations, industry publications and other sources. While we believe these estimates to be
accurate as of the date of this annual report, we have not independently verified the data from third-party sources and our internal data has not been verified by any independent source. In addition, our former director, Hugo Santa María
Guzmán, is a partner in APOYO Consultoría, and Roberto Abusada Salah, a director of the company, GMP and GyM, is a director of the Peruvian Economy Institute. We paid Great Place to Work
® Institute (Great Place to Work), a human resources consulting, research and training firm, for our employees to participate in their market survey referenced in this annual
report (Copyright © 2016 Great Place to Work ® Institute, Inc. All rights reserved.). In this annual report we present gross domestic
product (GDP) both on a nominal and real basis. Real GDP is nominal GDP adjusted to exclude the effect of inflation. Unless otherwise indicated, references to GDP are to real GDP.

Non-GAAP Financial Measure and Reconciliation

In this annual report, we present EBITDA, a non-GAAP financial measure. A non-GAAP financial measure is generally defined as one that purports to measure financial performance, financial position or cash flows but excludes or includes amounts that would not be so adjusted in the most
comparable IFRS measure. We define EBITDA as net profit plus: financial (expense) income, net; income tax; and depreciation and amortization.

We present EBITDA, a non-GAAP financial measure. A non-GAAP
financial measure is generally defined as one that purports to measure financial performance, financial position or cash flows but excludes or includes amounts that would not be so adjusted in the most comparable IFRS measure. We present EBITDA
because we believe it provides readers with a supplemental measure of the financial performance of our core operations that facilitates period-to-period comparisons on a
consistent basis. Furthermore, we regularly present EBITDA in our filings with the Lima Stock Exchange in Peru. Our management uses EBITDA, among other measures, for internal planning and performance measurement purposes. We believe that EBITDA is
useful in evaluating our operating performance compared to that of other companies operating in our sectors because the calculation of EBITDA and

EBITDA generally eliminates the effects of financing and income taxes and the accounting effects of capital spending, which items may vary for different companies for reasons unrelated to overall
operating performance. EBITDA should not be construed as an alternative to net profit or operating profit, as an indicator of operating performance, as an alternative to cash flow provided by operating activities or as a measure of liquidity (in
each case, as determined in accordance with IFRS). EBITDA, as calculated by us, may not be comparable to similarly titled measures reported by other companies. The following table sets forth the reconciliation of our net profit to EBITDA on a
consolidated basis.

Exchange Rates

The Peruvian sol is freely traded in the exchange market. Current Peruvian regulations on foreign investment allow foreign equity holders of
Peruvian companies to receive and repatriate 100% of the cash dividends distributed by these companies. Non-Peruvian equity holders are allowed to purchase foreign currency at free market currency rates
through any member of the Peruvian banking system and transfer such foreign currency outside Peru without restriction. Peruvian law in the past, however, has imposed restrictions on the conversion of Peruvian currency and the transfer of funds
abroad, and we cannot assure you that Peruvian law will continue to permit such payments, transfers, conversions or remittances without restrictions.

The following table sets forth, for the periods indicated, certain information regarding the exchange rates for soles per U.S. dollar, as
published by the SBS. The Federal Reserve Bank of New York does not report a noon buying rate for soles.

D. Risk Factors

Risk Relating to Recent Developments

Our reputation
has been adversely affected by our association with Odebrechts affiliates in Peru

We have participated in consortia with
Odebrecht affiliates in Peru. Our reputation has been adversely affected as a result of the plea agreements and criminal convictions of Odebrecht and certain key persons related to Odebrecht in connection with corruption, money laundering and
criminal organization. Peruvian authorities have initiated congressional inquiries and criminal investigations into the dealings of Odebrechts affiliates in Peru, the scope of which include certain consortia in which we participated. Moreover,
as a result, our company and certain of our former directors and executive officers have been the subject of congressional and criminal investigations related to corruption investigations. These investigations are ongoing.

Our reputation is a key factor in our clients evaluation of whether to engage our services, key industry players willingness to
partner with us, financial institutions willingness to provide us credit, and recruiting and retaining talented personnel to our company. The impact on our business reputation related to our association with Odebrecht and the alleged actions
of our former board members and executive officers has had, and is likely to continue to have, a material adverse effect on our business, financial condition and results of operation.

Investigations regarding potential corruption or other illegal acts could have a material adverse effect on our business, financial condition and
results of operations

The Lava Jato commission of the Peruvian congress has undertaken congressional inquiries into the
company and other construction companies in Peru, which have included certain of the companys former board members and executive officers.

Peruvian prosecutors have included José Graña Miró Quesada, the former Chairman of the company, in an investigation for
the crime of collusion, and Hernando Graña Acuña, a former board member of the company, for the crime of money laundering against the Peruvian government, each in connection with the IIRSA South project concession (tranches II and
III), in which we participated with Odebrecht. Gonzalo Ferraro Rey, the former Chief Infrastructure Officer of the company, has also been included in an investigation for the crime of money laundering in connection with the same project.

In connection with investigations relating to the IIRSA South project concession (tranches II and III), the Peruvian criminal prosecution has
moved to charge the company and our construction subsidiary, GyM, as criminal defendants in connection with the projects. Separately, a Peruvian Ad Hoc Prosecutor appointed by the Peruvian executive branch to investigate matters of corruption (the
Ad Hoc Prosecutor) has moved to directly include the company as a civilly-responsible third party. In response, the Peruvian First National Preparatory Investigation Court (Primer Juzgado de Investigación Preparatoria
Nacional) notified us of its decision to formally include the company and GyM in its criminal investigation. We have appealed the courts decision to include the company and GyM in the criminal investigation. A decision from the Peruvian
judiciary on whether our company constitutes a civilly-responsible third party remains pending. We cannot assure you that our position in these proceedings will prevail.

The Ad Hoc Prosecutor has also moved to directly include our subsidiary, GyM, as a civilly-responsible third party in the investigation
relating to Tranches 1 and 2 of Line 1 of the Lima Metro. A decision from the Peruvian judiciary regarding these matters remains pending, and we cannot assure you that our subsidiary will not be included or that our position would ultimately
prevail.

We cannot assure you that other of our former or current board members and executive officers will not be included in the
foregoing proceedings as criminal defendants or civilly-responsible third parties as well, or that the company will not be included in other investigations.

A conviction of corruption or settlements with government authorities could lead to criminal and civil fines as well as penalties, sanctions,
injunctions against future conduct, profit disgorgement, disqualifications from directly and indirectly engaging in certain types of business, the loss of business licenses or permits or other restrictions. Moreover, our alleged involvement in
corruption investigations, and any findings of wrongdoing in such investigations, could further damage our reputation and have a material adverse impact on our ability to compete for business. Such investigations may also adversely affect our
ability to pursue strategic projects, and could potentially result in the termination or modification of certain existing contracts or relationships. In addition, investigations could continue to divert managements attention and resources from
other issues facing our business.

There is substantial uncertainty with regard to the amount, timing and manner in which the payment for the
termination of the GSP gas pipeline concession will be paid

There is substantial uncertainty with regards to the payment
contemplated under the GSP gas pipeline concession contract as a result of the termination of the gas pipeline concession, including with respect to the amount, timing and manner in which the payment will be made or if it will be made at all.

Although the concession contract provides that payment must be made within one year of termination, the Peruvian Ministry of Energy and Mines
has not made payment or, to our knowledge, initiated the payment process or the auction process for a new concessionaire. As a result, we may be forced to assert our rights against the Peruvian government in judicial or arbitration proceedings,
which may place us in an adversarial position with the Peruvian government and/or our partners. We cannot assure you that we will pursue any such claims, or that any such claims would ultimately prevail in a timely manner, or at all.

To initiate arbitration against the Peruvian government, we need the approval of all three shareholders of GSP. We have sought such approval
on two occasions but have not succeeded. We cannot assure you that we will acquire the consent needed to initiate legal proceedings in the short term. Moreover, Enagás International, S.L. (Enagás) has initiated separate
international proceedings against the Peruvian government pursuant to international treaties, which may affect GSPs ability to initiate proceedings against the Peruvian government.

In 2016, in connection with efforts to restructure or sell Odebrechts participation in GSP, due to the corruption scandal surrounding
Odebrecht, Odebrecht contractually agreed to subordinate its claims under the concession to the other project partners, Enagás and ourselves. On January 2, 2018, we received a notification that Odebrecht commenced arbitration proceedings
against us and Enagás, seeking to invalidate the contractual subordination and to negotiate a direct sale with the Peruvian government. While we believe that the subordination arrangement with respect to Odebrechts claims in connection
with the anticipated payment is enforceable, we cannot assure you that our position will prevail. See Item 5.A. Operating and Financial Review and ProspectsOperating ResultsRecent Developments.

In addition, we have made certain estimates in our consolidated financial statements with respect to the expected payment for the termination
of the GSP contract. If our assumptions and estimates are incorrect, our actual results could differ significantly from those reflected in our consolidated financial statements. Failure to receive the expected payment on a timely basis, or at all,
would have a material adverse effect on our business, financial condition and results of operations.

We are in default under certain of our debt
instruments and may not reach agreement with our creditors to amend or waive the covenants

We are currently in default under
certain of our debt instruments and are initiating the process of renegotiating with our creditors under such instruments. See Item 13. Defaults, Dividend Arrrearages and Delinquencies. Failure to successfully renegotiate new payment
terms could force us to precipitate the sale of assets, including on unfavorable terms, to repay these debt instruments. Moreover, if we are not able to renegotiate the terms of these debt instruments or repay them promptly, our ability to obtain
financings, including performance guarantees or similar financings required under many of our business contracts, would be impaired, which may have a material adverse effect on our business, financial condition and results of operations.

We may not be able to sell assets on favorable terms or at all

As part of our strategic action plan, our board of directors has approved the sale of certain
non-strategic assets, to make payments in respect of debt related to the termination of the GSP gas pipeline concession. We cannot assure you that we will be able to sell assets on favorable terms or at all.
If we are not able to sell assets on a timely basis, our ability to address our liquidity needs could be adversely affected and we may breach our payment obligations under our debt related to the termination of the GSP gas pipeline concession.

Conversely, if we sell significant assets, our business and results of operations will be diminished.

If we cannot sell assets, we may not comply with the terms of our outstanding debt

We renegotiated with our creditors the terms of certain debt instruments related to the GSP project. We have agreed, among other things, to
sell assets to repay certain such debt instruments. For more information, see Item 5.A. Operating and Financial Review and ProspectsOperating ResultsRecent DevelopmentsStrategic Action PlanNegotiations with
Creditors. If we are unable to sell assets in a timely manner, we may be forced to renegotiate these debt instruments on unfavorable terms.

A class action civil lawsuit in the United States may adversely affect our company

A securities class action civil lawsuit has been filed against the company and certain of our former and current executive officers in the United States. The
suit is in early stages, and we cannot assure you that our position will prevail. If our position does not prevail, the case may have substantial adverse effects on our business, financial condition and results of operations.

We may be unable to access credit that we need to operate our business

Due to ongoing regulatory uncertainty, including with respect to Section II of Law 30737, our creditors and other banks operating in the
Peruvian market have placed restrictions on our ability, and the ability of other construction companies, to acquire future credit lines or other financings.

This may affect our ability to obtain financing for new or existing projects on favorable terms or at all, and also may render us unable to
compete for or win new projects.

Our business and financial condition could be materially and adversely affected if the Peruvian prosecutor
requires that we place an excessive amount of assets in trust

On February 13, 2017, the President of Peru issued an emergency
decree (decreto de urgencia N° 003-2017), prohibiting groups that have been, or whose officers or representatives have been convicted of, or have admitted to, corruption, money-laundering or similar
crimes (whether in Peru or elsewhere) from, among other things, transferring or selling any assets related to investments in Peru, including the proceeds of asset or equity sales, or sending money abroad without a governmental authorization. Section
II of Law 30737, promulgated on March 12, 2018 to replace the aforementioned emergency decree, includes companies that have been consortium partners of groups that have been, or whose officers or representatives have been, convicted of, or have
admitted to, corruption, money-laundering or similar crimes. Our company and our subsidiary GyM are two such companies. The law requires that these companies: suspend money transfers abroad; implement a compliance program and disclose information to
competent authorities; and create a trust of assets to guarantee eventual compensation in favor of the Peruvian government. A Peruvian prosecutor will indicate the amount of such guarantee, pursuant to Law 30733. On May 9, 2018, Supreme Decree
No. 096-2018-EF was passed, which provides guidelines for such determination. Nevertheless, we cannot assure you of the amount of this guarantee, nor can we assure you
that the Company will have sufficient assets to include in the required trust. Furthermore, we cannot assure you that these laws will not be expanded, or that subsequent laws will not be passed, that impose further obligations or restrictions on the
company and our subsidiaries.

Changes in key personnel could affect our future business

Our success depends significantly on the services of our senior management, board of directors and other key personnel. On February 27,
2017, our former chairman of the board, our former CEO and board member, and our former board member and the former chairman of our subsidiary GyM resigned from their positions at our company. Effective March 2, 2017, we appointed a new CEO,
and on March 31, 2017, our shareholders at the annual shareholders meeting appointed a new board of directors, replacing all but two of our existing directors. Moreover, other senior managers that have recently left the company.

While most of these officers have already been replaced, the replacement of existing directors and senior management is likely to have an
impact on our business and results of operations. Moreover, we cannot assure you that we will be able to continue to attract and retain senior management, qualified engineers and other key personnel.

INDECOPI and Peruvian prosecutors have initiated investigations in response to a news report alleging that certain construction companies in Peru,
Brazil and Spain, including our company, colluded to receive public contracts

In July 2017, media reports alleged that certain
construction companies in Peru, Brazil and Spain, including our company, colluded as a construction club to receive public contracts. As a result of these reports, the Peruvian National Institute for the Defense of Free Competition and
the Protection of Intellectual Property (INDECOPI) has initiated an investigation regarding the anti-competitive activities of construction companies in Peru, including our company, and have included a former employee of GyM in an
investigation for collusion. In July 2017, INDECOPI conducted a search of our facilities related to these allegations. To date, there is no pending investigation of the company.

We cannot predict what the outcome of the investigations will be, the timing of any resolution, or how the resulting consequences, if any, may
impact our business, financial condition and results of operations.

Risks Related to Our Company

Global economic conditions could adversely affect our financial performance

The global financial crisis and ensuing global recession in 2008 and 2009 had a significant adverse effect on the development of large-scale
infrastructure and real estate projects worldwide. More recently, global economic conditions, including slower growth in China, declines in global commodity, in particular oil and gas prices, the appreciation of the U.S. dollar against foreign
currencies, the withdrawal of investments from emerging markets and continued concerns about the U.S. and European economies, has generated economic uncertainty which could adversely affect private- and public-sector investments. The United Kingdom
voted to exit the European Union on June 23, 2016. As of the date hereof, the actions to be taken by the United Kingdom to effectively exit the European Union and the duration of this process are uncertain. The results of the referendum in the
United Kingdom have caused, and are expected to continue to cause, volatility in financial markets, which in turn could have substantial adverse effects on our business, financial condition and results of operations. On November 8, 2016,
Mr. Donald J. Trump was elected president of the United States. President Trump has espoused an inclination to consider greater restrictions on free trade and limitations on immigration. Changes in social, political, regulatory and
economic conditions in the United States or in laws and policies governing foreign trade could create uncertainty in the international markets and could have a negative impact on emerging market economies, including the Peruvian economy, which in
turn could have a negative impact on our operations. Future global economic conditions, in particular fluctuations in commodity prices and financings costs, may impact our clients investment decisions. Should our clients choose to postpone or
suspend new investments or delay or cancel the execution of existing projects as a result of global economic conditions, demand for our products and services, including our backlog, would decline, which may result in a decline in revenues and in
under-utilization of our capacity. In addition, our business may be impacted by adverse economic developments even after economic conditions have improved because of the lag time between when investments decisions are made and when the projects are
executed. Furthermore, financial difficulties suffered by our clients, joint operation partners, subcontractors or suppliers due to global economic conditions could result in payment delays or defaults, or increase our costs or adversely impact our
project execution. Accordingly, a global economic downturn could have a material adverse effect on our financial performance.

We face significant
competition in each of our markets

Each of the markets in which we operate is competitive. We compete on the basis of, among other
factors, price, performance, product and service quality, skill and execution capability, client relations, reputation and brand, and health, safety and environmental record. We face significant competition from both local and international players.
Some of these competitors may have greater resources than us or specialized expertise in certain sectors. In addition, a portion of our business is derived from open bidding processes which can be highly competitive. Certain of our markets are
highly fragmented with a large number of companies competing for market share. Our competitors may be more inclined to take greater or unusual risks or accept terms and conditions in a contract that we might not deem acceptable. Moreover, we cannot
assure you that we will not face new competition from industry players entering or expanding their operations in our markets. If we are unable to compete effectively, our ability to continue to grow our business or maintain our market share would be
affected. In addition, because one of the factors on which we generally compete is price, increased competition could impact our operating margins. Accordingly, our business and financial performance could be adversely affected by competition in our
markets.

A major change in Peruvian government policies could affect our business

Our business is significantly affected by national, regional and municipal government policies and regulations, including with respect to
infrastructure concessions or similar contracts to the private sector, public spending in infrastructure investment and government housing subsidies, among others. Any adverse change in government policies with respect to these matters could result
in a material adverse effect on our business and financial performance.

Social conflicts may disrupt infrastructure projects

Despite Perus ongoing economic growth and stabilization, high levels of poverty and unemployment and social and political tensions
continue to be pervasive problems in the country. Peru has, from time to time, experienced social and political turmoil, including riots, nationwide protests, strikes and street demonstrations. In recent years, certain regions experienced strikes
and protests related mainly to the environmental impact of mining activities, which resulted in commercial disruptions, including in the departments of Cajamarca and Arequipa. These protests may lead to the suspension of mining projects. Social
conflicts may disrupt, delay or suspend infrastructure projects in the future, which could have a material adverse effect on our business and financial performance.

New projects may require the prior approval of local indigenous communities

In September 2011, Peru enacted Law No. 29,785, regarding the Prior Consultation Right of Local Indigenous Communities, in accordance with
the International Labor Organization Convention No. 169 (Ley del Derecho a la Consulta Previa a los Pueblos Indígenas y Originarios, Reconocido en el Convenio 169 de la Organización Internacional del Trabajo). This law establishes
a prior consultation procedure (procedimiento de consulta previa) that the Peruvian government must carry out with local indigenous communities, whose rights may be directly affected by new legislative or administrative measures, including the
granting of certain permits or new concessions or similar contracts, such as for mining, energy and oil and gas projects. Local indigenous communities do not have a veto right; upon completion of this prior consultation procedure, the Peruvian
government retains the discretion to approve or reject the applicable legislative or administrative measure. We cannot assure you that these consultation procedures will not adversely affect new projects and concessions. Accordingly, our business
and financial performance may be materially and adversely affected.

Our backlog and our ratio of historical backlog to revenues may not be reliable
indicators of future revenues or profit

Our backlog amount is subject to revision over time and our ability to realize revenues
from our backlog is subject to a number of uncertainties. Cancellations, scope adjustments or deferrals may occur, from time to time, with respect to contracts reflected in our backlog and could reduce the amount of our backlog and the revenue and
profits that we actually earn. Contracts may also remain in our backlog for an extended period of time and poor performance could also impact our profit from the contracts in our backlog. In addition, our backlog is expressed in U.S. dollars based
on period-end exchange rates while a significant portion of our contracts are payable in soles or other local currencies. As a result, any depreciation of local currency would diminish the amount of revenues
eventually earned relative to backlog. As of December 31, 2016, one client, Ecopetrol, concentrated 33.5% of Morelcos backlog, and another client, Rio Alto, concentrated 44.9% of Stracons backlog. Moreover, the termination of the
GSP gas pipeline concession on January 24, 2017 has reduced our backlog as of December 31, 2016 by US$855 million, 30.2% of our E&C backlog and 21.4% of our total backlog. For more information, see Item 5.A. Operating and
Financial Review and ProspectsOperating ResultsRecent Developments. The amount of our backlog is not necessarily indicative of future revenues or profits related to the performance of the related contracts.

Our backlog may decline further. We cannot assure you that we will be able to obtain sufficient contracts in the future in number and
magnitude to grow our backlog. Additionally, the amount of new contracts that we obtain can fluctuate significantly from period to period due to factors that are beyond our control.

The ratio of our historical backlog to revenues earned in subsequent years is volatile and substantially affected by a number of factors, some
of which are outside our control, including levels of contract scope adjustments and our ability to enter into new contracts (which are substantially influenced by general economic conditions), delays and cancellations, foreign exchange rate
movements and our ability to increase the scale of our operations to expand the amount of work we carry out beyond that previously contracted. Accordingly, historical correlations between backlog and revenues may not recur in future periods. In
particular, you should not assume that the ratio of our future E&C segment revenues for 2018 to backlog as of December 31, 2017 that is currently expected to be realized in that year will be comparable to our historic ratios shown in
Item 4.B. Information on the CompanyBusiness OverviewBacklogE&C Backlog.

Our success depends on key personnel

Our success depends, to a significant degree, upon the services of our senior management, board of directors and other key
personnel. Members of our management team are not subject to long-term employment agreements or non-competition agreements with us. We cannot assure you that we will be successful in retaining our current
senior management or members of our board of directors, nor can we assure you that, in such event, we would be able to find suitable replacements. In addition, the success of our business depends on our ongoing ability to attract, train and retain
qualified engineers and other personnel. In recent years, the availability in Peru of qualified personnel who have the necessary expertise and experience has been lower than demand and, therefore, competition for human resources has become intense.
We cannot assure that we will be able to hire and retain the number of qualified personnel required to meet the needs of, or to grow, our business. If we are unable to attract, train and retain the qualified personnel that we require at reasonable
cost, our business and financial performance could be adversely affected.

Our success depends, to a large extent, on our reputation for the
quality, reliability, timely delivery and safety of our products and services

We believe our track record and reputation are key
factors in our clients evaluation of whether to engage our services and purchase our products, encouraging key industry players to partner with us, and recruiting and retaining talented personnel to our company. Our reputation is based, to a
large extent, on the quality, reliability, timeliness and safety of our products and services. If our products do not meet expected standards or we fail to meet our deadlines, our relationship with our clients and partners could suffer, the
reputation of our company could be adversely affected, we may not be invited to new bidding processes and our ability to capture new business could be severely diminished.

The nature of our business exposes us to potential liability claims and contract disputes

We may be subject to a variety of legal or administrative proceedings, liability claims or contract disputes. The government, clients and other
third parties may present claims against us for injury or damage caused, directly or indirectly, by our operations, for example for alleged failures in our engineering and construction, the operation of our infrastructure concessions (such as our
toll roads or the Lima Metro) and real estate developments we sell. Although we have adopted a range of insurance, risk management and risk avoidance programs designed to reduce potential liabilities, a catastrophic event resulting from the services
we have performed or products we have provided could result in significant professional or product liability, warranty or other claims against us as well as reputational harm, especially if public safety is impacted. We may in the future be named as
a defendant in legal proceedings where our clients or third parties may make a claim for damages or other remedies with respect to our projects or other matters. Any liability not covered by our insurance, or in excess of our insurance limits, could
result in a significant loss for us, which may affect our financial performance. Moreover, certain of our clients have executed the performance guarantees that we were required to deliver in connection with their project in order to gain leverage,
we believe, in the negotiation of contract disputes with us.

We are susceptible to operational risks that could affect our business and financial
performance

Our business is subject to numerous industry-specific operational risks, including natural disasters, adverse weather
conditions, operator error or other accidents, mechanical and technical failures, explosions and other events, many of which are beyond our control. Such occurrences could result in injury or loss of life, severe damage to and destruction of
property and equipment, business interruption, pollution and other environmental damage, clean-up responsibilities, regulatory requirements, investigations and penalties, potential liability claims and
contractual disputes. In addition, such occurrences could materially impact our reputation. Although we maintain comprehensive insurance covering our assets and operations at levels that our management believes to be adequate, our insurance coverage
will not be sufficient in all circumstances or to protect against all hazards. The occurrence of such an operational risk could have a material adverse effect on our business and financial performance.

Deterioration in our safety record could adversely affect our business and financial performance

Our ability to retain existing clients and attract new business is dependent on our ability to safely operate our business. Existing and
potential clients consider the safety record of their services providers to be of high importance in their decision to award service contracts. Some of our activities, in particular in our E&C segment, as well as our electricity networks
services line of business, can be high risk by their nature. If one or more accidents were to occur at a site, the affected client may terminate or cancel our contract and may be less likely to continue to use our services. We cannot assure you that
we will not experience accidents in the future, causing our safety record to deteriorate. Accidents may be more likely as we continue to grow, particularly if we are required to hire less experienced employees due to shortages of skilled labor.
Moreover, often times we do not perform these activities by ourselves and accidents can happen due to errors committed by partners and subcontractors over whom we have no control. Because many of our clients require us to report our safety metrics
to them as part of the bidding process and because a substantial part of our client base is comprised of major companies with high safety standards, a general deterioration in our safety record could have a material adverse impact on our business
including our ability to bid for new contracts.

Any safety incidents or deterioration in our safety record could adversely impact our
ability to attract and retain qualified employees. In addition, we could also be subject to liability for damages as a result of accidents and could incur penalties or fines for violations of applicable safety laws and regulations.

Increases in the prices of energy, raw materials, equipment or wages could increase our operating costs

Our business requires significant purchases of energy, raw materials and components, including, among others, large quantities of fuel, cement
and steel, as well as purchases or leases of equipment. Certain inputs used in our operations are susceptible to significant fluctuations in prices, over which we may have little control. The prices of some of these inputs are affected to a
significant extent by the prices of commodities, such as oil and iron. Global oil prices in particular have declined significantly in recent years, although they increased in 2016 and subsequently, and we cannot assure you that oil prices will not
continue to increase in the future (although increased oil prices would benefit revenues in our Energy line of business. Substantial increases in the prices of such commodities generally result in increases in our suppliers operating costs
and, consequently, lead to increases in the prices they charge for their products. Moreover, we do not have long-term contracts for the supply of our key inputs, and, as a result, if prices increase significantly or if we are required to find
alternative suppliers, our costs to procure these inputs may increase significantly. In addition, growing demand for labor, especially when coupled with shortages of qualified employees in the countries where we operate, may result in significant
wage inflation. To the extent that we are unable to pass along to our clients increases in the prices of our key inputs or increases in the wages that we must pay, our operating margins could be materially adversely impacted.

We may not be able to obtain financing on favorable terms

Our ability to undertake large investments (particularly in our Infrastructure and Real Estate segments) or consummate significant acquisitions
will depend on the availability of equity and debt financing. We cannot assure you that we will be able to obtain new financings in the future on favorable terms or at all. Our ability to obtain financings will depend in part upon prevailing
conditions in credit and capital markets, which are beyond our control. In 2008 and 2009, global markets suffered turmoil, which significantly constrained the availability of new financings. In addition, our ability to obtain new financing, or
refinance existing debt, may at certain times be adversely affected by the cyclicality of our business, particularly our E&C segment, as has occurred in the past. Furthermore, in response to the ensuing global economic recession in 2009, many
countries, in particular the United States as well as the countries where we operate, have maintained target interest rates at very low levels. However, more recently, the U.S. Federal Reserve began to increase target interest rates in the United
States. Most emerging markets have been affected by this change in the U.S. monetary policy, resulting in a withdrawal of investments and increased volatility in the value of their currencies. If interest rates rise significantly in the United
States, emerging market economies, including Peru, could find it more difficult and expensive to borrow capital and refinance existing debt. Higher interest rates globally or in Peru would in turn impact our costs of funding. If adequate funds are
not available, or are not available on favorable terms, we may not be able to make future investments or take advantage of acquisitions or other opportunities.

We may not be able to recover on claims against clients for payment

If a client fails to pay our invoices on time or defaults in making its payments to us, we could incur significant losses. We occasionally
bring claims against clients, principally the government, for delayed payments, additional costs that exceed the contract price or for amounts not included in the original contract price, including change orders. These types of claims can occur due
to matters such as owner-caused delays or changes from the initial project scope, and, occasionally, they can be the subject of lengthy proceedings. When these types of events occur and unresolved claims are pending, we may invest significant
working capital in projects to cover cost overruns pending the resolution of the relevant claims. Moreover, we have recently encountered difficulties collecting on claims, even following successful arbitration awards, particularly against the
government. A failure to promptly recover on these types of claims and change orders could have a material adverse effect on our financial performance.

If we are unable to enter into consortia or other strategic alliances, our ability to compete for new business may be adversely affected

We may join with other companies to form joint operations or other strategic alliances to compete for a specific concession or contract,
including with partners that contribute expertise in a specific field. Because a consortium or alliance can often offer stronger combined qualifications than a company on a stand-alone basis, these arrangements can be important to the success of a
particular bid. If we are unable to enter into consortia or other strategic alliances, our ability to compete for new business may be adversely affected.

Our consortia and other strategic alliances may be affected by disputes with, or the unsatisfactory performance by, our partners

Consortia and other strategic alliances that we enter into as part of our business, including arrangements where operating control may be
shared with unaffiliated third parties, may involve risks not otherwise present when we operate independently, including: sharing approval rights over major decisions; responsibility for our partners unpaid obligations or liabilities; and
inconsistencies in our and our partners economic or business interests or goals. Any disputes between us and our partners may result in delays, litigation or operational impasses. We may also incur liabilities as a result of action taken by
our partners. In addition, if we participate in consortia or other strategic alliances where we are not the controlling party, we may have limited control over operation decisions and actions and the success of the consortium or other strategic
alliance will depend largely on the performance of our partners. These risks could adversely affect our ability to transact the business that is the subject of such consortium or other strategic alliance, and could result in the termination of the
applicable concession or contract. Under these circumstances, we may be required to make additional investments and provide additional services to ensure adequate performance and delivery. These additional obligations could result in reduced profits
or, in some cases, increased liabilities or significant losses for us. In addition, failure by a partner to comply with applicable laws or regulations could negatively impact our business and, in the case of government contracts, could result in
fines, suspension or even debarment from participating in bidding processes. As a result, our business and financial performance could be adversely affected by disputes involving our consortia or other strategic alliances. We have recently been
involved in ongoing disputes, including arbitration proceedings, with our minority partner in Adexus. These disputes could result in disruptions in Adexus operations.

We are dependent upon third parties to complete many of our contractual obligations

We rely on third-party suppliers to provide a significant amount of the materials and equipment used in our businesses. A portion of the work
performed under our infrastructure concessions and, to a lesser extent, other contracts is performed by third-party subcontractors. As a result, the timely completion and quality of our projects may depend on factors beyond our control, including
the quality and timeliness of the delivery of materials supplied for use in the project and the technical skills of subcontractors hired for the project. If we are unable to find qualified suppliers or hire qualified subcontractors, our ability to
meet our contractual obligations could be impaired. In addition, if the amount we are required to pay for supplies, equipment or subcontractors exceeds what we have estimated, we may suffer losses under our contract. If a supplier or a subcontractor
fails to provide supplies, equipment or services as required under a negotiated arrangement for any reason, or provides supplies, equipment or services that are not of an acceptable quality, we may be required to source those supplies, equipment or
services on a delayed basis or at a higher price than anticipated, which could impact our financial performance. In addition, faulty materials or equipment could result in claims against us for failure to meet contractual specifications, and failure
by suppliers or subcontractors to comply with applicable laws and regulations could negatively impact our reputation and our business and, in the case of government contracts, could result in fines, suspension or even debarment from participating in
bidding processes. These risks may be intensified during economic downturns if these suppliers or subcontractors experience financial difficulties. As a result, our business and financial performance may be adversely affected by our dependence on
third-party providers.

Debarment from participating in government bidding processes would have a material adverse effect on our business and
financial performance

We would face debarment from participating in government bidding processes for one to three years if we were
found to have violated certain provisions of the Peruvian State Contracting Law (Ley de Contrataciones del Estado). We are required to comply with a large number of contractual obligations with the government in our business, and we cannot assure
you that we will be in full compliance at all times. Moreover, such a debarment would affect the ability of our entire company (including any of our subsidiaries), and not just the line of business where the alleged violation took place, to
participate in government bids under the Peruvian State Contracting Law. In April 2013, Perupetro initiated an administrative proceeding against a subsidiary in our E&C segment, claiming that the subsidiary had submitted a bid to provide
engineering services while not being in compliance with certain technical requirements. We lost the administrative proceeding as well as the first and second instances of the judicial proceeding we had initiated to contest such administrative
proceeding. We appealed the adverse judgment and are currently in annulment proceedings. Although we believe that the likelihood of an adverse outcome in this proceeding is remote, an adverse outcome would affect that particular subsidiarys
participation in government bidding processes under the Peruvian State Contracting Law. Subsequently, we canceled the road maintenance services contract because the regional government of Cusco did not pay any valuations (January, February and March
of 2014) and did not give us access to the entire stretch of the related road. We have initiated an action against the regional government of Cusco for an amount of S/.97.4 million, and the government has filed a counterclaim for S/.403 million. All
these proceedings remain pending as of the date of this annual report, and we cannot assure you that our position will prevail.

During
2016, 11% of our revenues on a consolidated basis was derived from public sector contracts in Peru (excluding public infrastructure concessions). As a result, if our company is debarred from participating in government bidding processes, our
business and financial performance would be materially and adversely affected.

We may not be able to successfully expand outside of Peru

One of our long term strategies has been to continue to expand our operations outside of Peru, particularly in Chile and Colombia,
and we expect that our international operations could become a more significant part of our consolidated business in future. We cannot assure you that we will be able to replicate our success in Peru in other countries. Our international expansion
is subject to additional challenges, including: our ability to assimilate cultural differences and practices; our limited familiarity with local laws, regulators and contractors; our ability to attract and manage foreign personnel; the absence of a
local workforce formed in our corporate values and familiar with our operations; competition in foreign markets, including from industry players with significantly greater local experience and reputation; and other risks specific to these countries.
Many countries in Latin America have suffered significant economic, political and social crises in the past, and these events may occur again in the future. If we are unable to overcome these challenges, we may not be able to successfully expand
internationally.

We may not be able to make successful acquisitions

Part of our long-term strategy has been to evaluate strategic acquisition opportunities to expand our operations and geographic footprint,
especially in Chile and Colombia. We may not be able to identify appropriate acquisition opportunities, or, if we do, we may overpay for these acquisitions or may not otherwise be able to negotiate terms and conditions that are acceptable to us. We
may also face difficulties obtaining financing to pay for acquisitions. In addition, we may not be able to obtain regulatory approvals, including antitrust approvals, required to consummate acquisitions. Furthermore, even if we are able to
successfully consummate an acquisition, we may encounter challenges in integrating the acquired business effectively and profitably into our operations. The integration of an acquisition involves a number of factors that may affect our operations,
including diversion of managements attention, difficulties in retaining personnel and entry into unfamiliar markets. Acquired businesses may not achieve the levels of productivity anticipated or otherwise perform as expected. Acquisitions may
bring us into businesses we have not previously

conducted and expose us to additional business risks that are different from those we have traditionally experienced, including new geographic, market, operating and financial risks. Moreover,
acquisitions involve special risks, including the potential assumption of unanticipated liabilities and contingencies. Even if such liabilities are assumed by the sellers, we may have difficulties enforcing our rights, contractual or otherwise. We
cannot assure you that future acquisitions will meet our strategic objectives.

Failure to comply with, or changes in, laws or regulations could
have a material adverse effect on our business and financial performance

We operate in highly regulated industries. Our business
and financial performance depends on our and our clients ability to comply on a timely and efficient basis with extensive national, regional and municipal laws and regulations relating to, among other matters, environmental, health and safety,
building and zoning, labor, tax and other matters. The cost of complying with these laws and regulations can be substantial. In addition, compliance with these laws and regulations can cause scheduling delays. Although we believe we are in
compliance with all applicable concessions, other similar contracts, laws and regulations in all material respects, we cannot assure you we have been or will be at all times in full compliance. Failure by us or our clients to comply with our
concessions, similar contracts or these laws and regulations could result in a range of adverse consequences for our business, including subjecting us to significant fines, civil liabilities and criminal sanctions, requiring us to comply with costly
restorative orders, the shutdown of operations and revocation of permits and termination of concessions or similar contracts. In addition, we cannot assure you that future changes to existing laws and regulations, or stricter interpretation or
enforcement of existing laws and regulations, will not impair our ability to comply with such laws and regulations or increase our compliance costs.

We may be held liable for environmental damage caused by our operations

The nature of certain of our operations requires us to assume risks of causing environmental and other damages. We may be held liable for the
environmental damage we cause, including the incidental consequences of human exposure to hazardous substances or other environmental damage. We may be subject to clean up costs or penalties in the event of certain discharges into the environment
and/or environmental contamination and damage. Our environmental liability insurance may not be sufficient or may not apply to certain types of environmental damage. Any substantial liability for environmental damage could have a material adverse
effect on our financial performance.

New environmental regulation as a result of climate change could impact our business and financial performance

Growing concerns about climate change could result in the imposition of additional or more stringent environmental requirements or
regulations. For example, there are ongoing international efforts to address greenhouse emissions, such as the Kyoto Protocol or the more recent Paris Agreement, which are in various stages of negotiation and implementation. If more stringent
environmental regulation is adopted in the countries where we operate, we may be obliged to incur higher expenditures than anticipated, adversely affecting our financial performance. In addition, future remediation requirements in the event that we
are found responsible for environmental damage may be substantial, which could impact our financial condition. Moreover, more stringent environmental regulation could increase the costs of projects for our clients or, in some cases, prevent a
project from going forward, thereby potentially reducing the demand for our services. Accordingly, new environmental regulation could have a material adverse effect on our business and financial performance.

We may not be able to effectively protect ourselves against financial market risks

Our operations are exposed to financial market risks, such as risks related to exchange rates, commodity prices and, to a lesser extent,
interest rates. Fluctuations in currency, commodity prices or interest rates could adversely affect our financial performance. We cannot assure you that derivative financial instruments will protect us from the adverse effects of financial market
risks. While hedging transactions are intended to reduce market risks, such transactions may expose us to other risks, such as counterparty risk. We may not be able to adequately protect ourselves against financial market risks and may not
ultimately achieve an economic benefit from our hedging strategy.

The loss of a key client in some of our lines of business may affect our business
and financial performance

In some of our lines of business, such as our Infrastructure and Technical Services segments, a
substantial amount of the revenue we receive is concentrated among a limited number of clients, including the Peruvian government. If one or more of these major clients fail or delay in paying our fees, or if there is a significant reduction or
cancellation of business by one or more of these major clients, our business and financial performance may be adversely affected. In particular we cannot assure you that Enel, which acquired Enersis (from whom we acquired our electricity networks
services line of business in 2011), will not reduce its use of our services. If we are not able to capture new clients to replace the loss of business from existing key clients, our financial performance may be adversely affected.

Our use of the
percentage-of-completion method of accounting for our Engineering and Construction segment could result in a reduction of previously recorded profits

In accordance with IFRS, we measure and recognize a large portion of our revenues under the percentage-of-completion accounting methodology. This methodology allows us to recognize revenues ratably over the life of a contract, without regard to the timing of receipt of cash payments, by comparing
the amount of the costs incurred to date against the total amount of costs expected to be incurred. The effect of revisions to estimated costs, and thus revenues, is recorded when the amounts are known and can be reasonably estimated. These
revisions can occur at any time and could be material. On a historical basis, we believe that we have made reasonably reliable estimates of the progress towards completion on our long-term contracts. However, given the uncertainties associated with
these types of contracts and inherent in the nature of some of the industries in which we operate, it is possible for actual costs to vary from estimates previously made, which may result in reductions or reversals of previously recorded profits.

Labor unrest could adversely affect our financial performance

All of our manual laborers and a portion of our employees are members of labor unions. Our practice is generally to extend benefits we offer
our unionized employees to non-unionized employees. In our E&C segment, collective bargaining agreements are negotiated at two levels, on an annual basis between the Peruvian National Federation of Civil
Construction and the Peruvian Chamber of Construction, without our direct involvement, and on a per project basis directly between the unions and us in accordance with such annual agreement. We also have collective agreements with our employees in
certain of our business segments, which are also negotiated periodically. Although we consider that our relationship with unions are currently positive, we cannot assure you that we will not experience work slowdowns, work stoppages, strikes or
other labor disputes in the future, which could result in the interruption or delay of our operations. Such interruptions or delays could have an adverse impact on our business, including on the cost of our projects and our ability to make timely
delivery. Moreover, our operations may also be affected by labor unrest in our clients or our partners workforce.

The proceeds from our
insurance policies may not be sufficient and we may not be insured against all risks

We maintain insurance coverage both as a
corporate risk management strategy and in order to satisfy the requirements under certain regulations and contracts. We cannot assure you that proceeds from our insurance policies, however, will be sufficient to cover the damages resulting from any
event covered by such policies. Certain risks are not covered under the terms of our insurance policies, such as interruption of operations. In such event, we may incur significant expenses to rebuild our facilities, repair or replace our equipment,
or cover other damages. In addition, if any of our third-party insurers fail, abruptly cancel our coverage or otherwise cannot satisfy their insurance requirements to us, then our overall risk exposure and operational expenses could be increased.
Moreover, we may not be able to renew our insurance policies on favorable terms, or at all. Although in the past we have been generally able to cover our insurance needs, we cannot assure you that we will be able to secure all necessary insurance in
the future.

An increase in import duties and controls may have a material adverse effect on our financial performance

Our future success depends in part on our ability to select and purchase quality mechanical instruments and equipment at attractive prices.
While we have historically been able to do so, such instruments and equipment may become subject to higher import taxes than currently apply. We cannot assure you that there will not be further increases in import taxes, changes in laws related to
imports or the imposition of quotas by countries from which we import mechanical instruments and equipment, which could have a material adverse effect on our business.

The government may declare the nullity of public bidding processes after we have been awarded a project or concession

Even if we win the public bidding for a project or concession, the government may subsequently declare the process void for political,
budgetary or other reasons and may cancel or terminate the project or concession awarded to us. For example, in June 2014, we were determined the winner of a public bidding for a concession to operate the fare collection system of Limas
integrated transportation system for a period of 16 years. However, in January 2015, the Municipality of Lima notified us that the board of directors of the Instituto Metropolitano Protransporte de Lima  Protransporte had declared the nullity
of the public bidding process, based on a report issued by the Peruvian Ministry of Economy and Finance, which concluded that the Ministry should have pronounced itself with respect to the concession prior to the bidding process instead of
afterwards. We initiated a judicial proceeding in July 2015 to challenge such declaration of nullity, which proceedings are currently under way.If upheld by the courts, the declaration of nullity of projects or concessions awarded to
us could affect our future results of operations. Moreover, the uncertainty that results from these type of decisions may adversely impact investor confidence in Peru and our business.

Additional Risks Related to our Engineering and Construction Business

We are vulnerable to the cyclical nature of the end-markets we serve

Demand for our engineering and construction services is dependent on conditions in the end-markets we
serve, which include, among others, the mining, power, oil and gas, transportation, real estate and other infrastructure sectors in Peru, as well as the mining sector in Chile and the energy sector in Colombia. Consequently, our engineering and
construction business is closely linked to the performance and growth of these sectors, and it is exposed to many of the risks faced by our clients operating in these sectors, over which we have no control. These industries tend to be cyclical in
nature and, as a result, although downturns can impact our entire company, our engineering and construction business has historically been subject to periods of very high and low demand. For example, between 2000 and 2003, there was a significant
decline in activity in the Peruvian real estate and construction sectors, which consequently affected our and our competitors business and financial performance during that time. Factors that can affect these sectors include, among others,
macroeconomic conditions, climate conditions, the level of private and public investment, the availability of credit, changes in laws and regulations and political and social stability. The mining and oil and gas sectors, in particular, are also
driven by worldwide demand for the underlying commodities, including, among others, silver, gold, copper, oil and gas, which can be affected by such other factors as global economic conditions and geopolitical affairs. The decline in recent years in
prices for minerals, oil and gas has had a significant impact on our clients exploration and production activities and, as a result, on their demand for our engineering and construction services. Accordingly, continuing adverse developments in
the end-markets served by our engineering and construction business could have a material adverse effect on our financial performance.

Decreases in capital investments by our clients may adversely affect the demand for our services

Our engineering and construction business is directly affected by changes in private-sector and, to a lesser extent, public-sector investments
for large-scale infrastructure projects. In addition, our engineering and construction business is directly affected by the availability and cost of financings for these projects. In the markets where we operate, investments and financings for
large-scale projects have historically been influenced by macroeconomic and other factors which are beyond our control, including in the case of public-sector investment, government spending levels. As a result, we cannot assure you that clients
will not choose to limit or not undertake new projects or delay, suspend or cancel existing projects. Further reductions in anticipated capital investments or available financing for large-scale projects could have a material adverse effect on our
financial performance. Public and private investment in Peru, Colombia and Chile slowed significantly during 2016 and 2017 as a result of market conditions and, in the case of Peru, as a result of corruption investigations and political uncertainty.

Our revenues may fluctuate based on project cycles, which we may not control

The substantial majority of the revenues from our engineering and construction business is generated from project awards, the timing of which
may be unpredictable and outside of our control, especially considering the highly competitive bidding processes and complex and lengthy negotiations they involve. These processes can be impacted by a wide variety of outside factors including
governmental approvals, financing contingencies and overall market and economic conditions. Moreover, because a significant portion of our revenues is generated from large-scale projects, our results of operations can fluctuate quarterly or yearly
depending on whether and when project awards occur and the commencement and progress of work under awarded contracts. As a result, we are subject to the risk that revenues may not be derived from awarded projects as quickly as anticipated.

Our business may be adversely affected if we incorrectly estimate the costs of our projects

We conduct our engineering and construction business under various types of contractual arrangements where costs are estimated in advance. In
some of our contracts (i.e., lump-sum, unit price and EPC), we bear the risk of some or all unanticipated cost overruns, including due to inflation or certain unforeseen events. Risks under contracts which
could result in cost overruns include: difficulties in performance of our subcontractors, suppliers, or other third parties; changes in laws and regulations or difficulties in obtaining permits or other approvals; unanticipated technical problems;
unforeseen increases in the cost of inputs, components, equipment, labor, or the inability to obtain these on a timely basis; delays caused by weather conditions; incorrect assumptions related to productivity or scheduling estimates; and project
modifications that create unanticipated costs or delays. These risks tend to be exacerbated for longer term contracts since there is increased risk that the circumstances under which we based our original bid could change. In many of our contracts,
we may not be able to obtain compensation for additional work performed or expenses incurred. Our failure to estimate accurately the resources and time required to complete a project could adversely affect our profitability. Even under our cost-plus
contracts, our inability to complete projects within the estimated budget could affect our relationship with our clients and negatively impact awards of future contracts. As a result, if we incorrectly estimate the costs of our projects, our
business and financial performance could be adversely affected.

We may be unable to deliver our services in a timely manner

The success of our engineering and construction business depends on our ability to meet the standards and schedules required by our clients.
Significant delays that prevent us from providing our services on agreed time frames could adversely affect our client relations and reputation. Delays may occur for a number of reasons, including as a result of our inability to adequately foresee
the needs of our clients; delays caused by our joint operation partners, subcontractors or suppliers; insufficient production capacity; equipment failure; shortage of qualified workers; changes to customs regulations; and natural disasters. Failure
to finish construction by the contractual completion date set forth in the contract could result in costs that reduce our projected profit margins, including a requirement to pay daily penalties and damages. If we are unable to meet deadlines,
either due to internal problems or as a result of events over which we have no control, we may lose the trust of our clients and, therefore, experience a decrease in the demand for our services. In such event, our business and financial performance
could be adversely affected.

We may not be able to obtain compensation for additional work or expenses incurred as a result of client-requested
change orders

Clients often determine, after commencement of the project, to change various elements of the project. Some of our
contracts may also require that clients provide us with design or engineering information or with equipment or materials to be used on the project, and, in some cases, the client may provide us with deficient design or engineering information or
equipment or materials or may provide the information or equipment or materials to us later than required by the project schedule. Our project contracts generally require the client to compensate us for additional work or expenses incurred due to
client requested change orders or failure of the client to provide us with specified design or engineering information or equipment or materials. Under these circumstances, we generally negotiate with the client with respect to the amount of
additional time required to make these changes and the compensation to be paid to us. We are subject to the risk that we are unable to obtain, through negotiation, arbitration, litigation or otherwise, adequate amounts to compensate us for the
additional work or expenses incurred by us due to client-requested change orders or failure by the client to timely provide required items. A failure to obtain adequate compensation for these matters could require us to record an adjustment to
amounts of revenue and gross profit that were recognized in prior periods. Any such adjustments, if substantial, could have a material adverse effect on our financial performance.

We may have difficulty obtaining performance bonds that we require in the normal course of our operations

In our engineering and construction business, it is industry practice for customers to require performance bonds or other forms of credit
enhancement to secure, among other things, bids, advance payments and performance. We cannot assure you that in the future we will not encounter difficulties in obtaining such performance bonds or credit enhancements. The Peruvian market for these
types of credit instruments is small; moreover, under Peruvian banking regulations, lenders are required to impose limits on the amount of credit they extend to a group of affiliated companies. Failure to provide performance bonds or credit
enhancements on terms required by clients may result in our inability to compete for or win new projects.

Additional Risks Related to our
Infrastructure Business

A substantial or extended decline in oil prices may adversely affect our financial performance

A substantial part of the revenues of our infrastructure business depends upon prevailing prices for oil. Historically, oil prices and markets
have been volatile and are likely to continue to be volatile in the future. Moreover, global oil prices have declined significantly in recent years, with the average Brent crude prices declining from US$111.65 in 2012, US$108.64 in 2013 and US$99.02
in 2014 to US$52.46 per barrel in 2015 and US$43.55 per barrel in 2016. During 2017, the average Brent crude price was US$52.84 per barrel.Oil is a commodity and its price is subject to wide fluctuations in response to
relatively minor changes in supply and demand for oil, market uncertainty, and a variety of additional factors beyond our control. Those factors include, among others: global demand and supply; political developments in producing regions; weather
conditions; governmental regulations; international conflicts and acts of terrorism; the price and availability of alternative sources of energy; and overall local and global economic conditions. Moreover, lower oil prices may not only decrease our
revenues on a per unit basis, but may also reduce the amount of oil we can produce economically, if any, and, as such, may have a negative impact on the reserves of the fields in which we operate. As result, our financial performance could be
materially and adversely affected by declines in oil prices.

Our reserves estimates depend on many assumptions that may turn out to be inaccurate
and are not subject to review by independent reserve auditors

The process of estimating oil and gas reserves is complex, although
the fields where we produce oil and gas are mature (Block I has been in production for over 100 years, Block III for approximately 100 years, Block IV for approximately 95 years and Block V for over 50 years). In order to prepare our reserves
estimates presented in this annual report, we must project production rates and timing of development expenditures as well as analyze available geological, geophysical, production and engineering data, and the extent, quality and reliability of this
data can vary. The process also requires economic assumptions about matters, such as oil prices,



28

##### Table of Contents

drilling and operating expenses, capital expenditures, taxes, and availability of funds. Therefore, estimates of reserves are inherently imprecise. Moreover, our reserve estimates included in
this annual report have been prepared internally by our team of engineers, and have not been audited or reviewed by independent engineers. Actual future production, oil and gas prices, revenues, taxes, development expenditures, operating expenses
and quantities of recoverable reserves will most likely vary from the estimates presented in this annual report, and those variances may be material. Any significant variance could materially affect the estimated reserves of the fields in which we
operate.

Our return on our investment in our concessions may not meet estimated returns

Our return on any investment in a concession is based on the terms and conditions of the concession, its duration and the amount of capital
invested as well as the amount of revenues collected, debt service costs, payment of penalties and other factors. For example, traffic volume at toll roads may be affected by a number of factors beyond our control, including security conditions;
general economic conditions; demographic changes; fuel prices; reduction in commercial or industrial activities in the regions served by the roads; and natural disasters. Decreased traffic at Norvial could adversely affect our financial performance.
Although some of our concessions allow for adjustments based on economic conditions, certain concessions provide that adjustment requests be approved only if certain limited events specified in our concession contracts have occurred. If a request of
adjustment is not granted, our financial performance could be affected. Given these factors and the possibility that governmental authorities could implement policies that affect our contractual return on investment in a way that we did not
anticipate, we cannot assure you that our return on any investment under any concession will meet our estimates.

Governmental entities may
terminate prematurely our concessions and similar contracts under various circumstances, some of which are beyond our control

Our
ability to continue operating our concessions and similar public-sector contracts depends on governmental authorities, which may terminate the concession or contract pursuant to the provisions set forth therein or in accordance with applicable
legislation, including the failure to comply with any contractual terms (including the concessionaires default on debt) or applicable law. Moreover, the relevant governmental authority may terminate and/or repossess a concession at any time,
if, in accordance with applicable law, the governmental authority determines that it is in the public interest to do so. The relevant governmental authority may also assume the operation of a concession in certain emergency situations, such as war,
public disturbance or threat to national security. In addition, in the case of force majeure, the relevant governmental authority may require us to implement certain changes to our operations. If the government terminates any of our
concessions, under Peruvian law, it is generally required to compensate us for the amount of our unrecovered investment, unless the concession is revoked pursuant to applicable law or the terms of the concession which would imply a serious breach of
the concessions terms by us. Such compensation process is likely to be time consuming and the amount paid to us may not fully compensate us. We cannot assure you that we would receive such compensation on a timely basis or in an amount
equivalent to the value of our investment in a concession plus lost profits.

We are exposed to risks related to the operation and maintenance of
our concessions and similar contracts

The operation and maintenance requirements under our concessions could encounter delays or
cause us to exceed our budgeted costs for such projects, which could limit our ability to realize the expected return on these projects, increase our operating or capital expenses and adversely affect our business and financial performance. In
addition, our operations may be adversely affected by interruptions or failures in the technology and infrastructure systems that we use to support our operations, including toll road collection and traffic measurement systems. The Lima Metro in
particular may be susceptible to outages due to power loss, telecommunications failures and similar events. The failure of any of our technology systems may cause disruptions in our operations, adversely affecting our profitability. While we have
business continuity plans in place to reduce the adverse impact of information technology system failures on our operations, we cannot assure you that these plans will be effective. Furthermore, accidents and natural disasters may also disrupt the
construction, operation or maintenance of our projects and concessions, which could adversely affect our business and financial performance.

We may
not be successful in obtaining new concessions

The market for infrastructure concessions in Peru is competitive. We compete with
Peruvian and foreign companies for infrastructure concessions in Peru, some of whom may have greater financial and other resources or particular expertise pertinent to a specific concession. Additionally, our public-sector clients may face budget
deficits that may prohibit the development of infrastructure concessions, which could affect our business. We may also not be able to obtain additional concessions if the government decides not to award new concessions, due to budget constraints or
policy changes or because alternative financing mechanisms are used. Recently, the awarding of concessions and the use of public-private associations in Peru have stalled, due in part to concerns related to the corruption scandal surrounding
Odebrecht and its potential effect on government officials in the country. Our inability to bid for or obtain new concessions may adversely affect our business and financial performance.

Our contract with Petroperú S.A. (Petroperú) for fuel storage at the
South terminal is currently scheduled to expire in August 2018. Moreover, we cannot assure you whether or when we will undertake any of the projects that have been awarded to us but for which contract negotiations are ongoing or stalled, in
particular the concessions for Via Expresa Sur and Via Expresa Javier Prado.

Additional Risks Related to our Real Estate Business

We are exposed to risks associated with the development of real estate

Our real estate business is subject to the risks that generally affect the real estate industry, such as availability and prices of suitable
land, environmental and zoning regulations, interruptions in supply and volatility of the prices of construction materials and equipment, and changes in the demand for real estate. Our real estate business is specifically affected by the following
risks: macroeconomic conditions in Peru that may impact the growth of the real estate sector as a whole, particularly in the residential market, including an increase in unemployment or a decrease in wage levels; an increase in prevailing interest
rates or lack of available credit; changes in government subsidies for affordable housing; unfavorable real estate market conditions, such as an oversupply of residential units or scarcity of suitable land in particular areas; the level of customer
interest in our new projects or the sales price per unit necessary to sell the unit may be lower than expected; customer perception of the security, convenience and attractiveness of our projects and the areas in which they are located; cost
overruns, many of which may be beyond our control, that exceed our estimates and affect our profit margins, including the price of labor, land, insurance, taxes and public charges; the construction and sale of units may not be completed on schedule;
bankruptcy or significant financial difficulties of large industry players, which cause a loss of confidence in the industry; and restrictions on real estate development imposed by local, regional and national laws and
regulations.    Recently, real estate sales have slowed due to modifications by the government to a program (Bono de Buen Pagador) that encourages social interest housing sales as well as less access to credit. The
occurrence of any of the above events may have a material adverse effect on our business and financial performance.

Real estate prices may not
continue to rise and may decline

Real estate prices in Peru have risen significantly over the last decade. We cannot assure you
that this increase in real estate prices does not represent a bubble. Real estate prices in Peru may not continue to rise or may decline significantly, particularly if financing costs rise or consumer confidence in the real estate market erodes. If
real estate prices decline significantly, our business and financial performance could be materially and adversely affected.

Our business may be
adversely affected if we are not able to obtain the necessary licenses and/or authorizations for our developments in due time

Real
estate development requires obtaining certain licenses, authorizations and registrations. In Peru, local authorities are responsible for issuing most of the licenses that are required during the development stage, including zoning, demolition and
construction licenses, among others. Currently, we have approximately 22 real estate projects in various stages of development. For some of these projects, we have not yet initiated the administrative proceedings before the appropriate authorities,
or such proceedings are pending approval.A denial or an extended delay in issuing licenses, authorizations or registrations may render land unsuitable for development, delay the completion of planned projects, increase our costs and
adversely affect our business and financial performance. Scarcity of financing and/or an increase in interest rates could decrease the demand for real estate properties.

The scarcity of financing and/or an increase in interest rates may adversely affect the ability or willingness of prospective buyers to
purchase our real estate properties. In most cases, the purchasers of our residential or commercial properties finance at least part of the purchase price with mortgage loans. In 2016, approximately 95% of our residential units was sold to
purchasers who received government subsidies to finance the purchase homes. An increase in interest rates, whether as a result of market conditions or government action or otherwise, may cause a decrease in the demand for our residential and
commercial properties and for land development, as well as an increase of our own financing costs, which may adversely affect our business and financial performance.

We may experience difficulties in finding desirable land and increases in the price of land may increase our cost of sales and decrease our earnings

The continued growth of our real estate business depends in large part on our ability to continue to acquire land and to do so at
a reasonable cost. As more developers enter or expand their operations in the Peruvian real estate sector, land prices could rise significantly and suitable land could become scarce due to increased demand or decreased supply. A resulting rise in
land prices may increase our cost of sales and decrease our earnings. We may not be able to acquire suitable land at reasonable prices in the future, which may have a negative impact on our financial performance.

##### Table of Contents

Changing market conditions may adversely affect our ability to sell home inventories in our land and at
expected prices

There is a lag between the time we acquire land and the time that we can bring the developed properties to market.
Lag time varies on a project-by-project basis. As a result, we face the risk that demand for real estate may decline or that other developments may occur during this
period that affect market conditions, and that we will not be able to dispose of developed properties or undeveloped land at expected prices or profit margins or within anticipated time frames or at all. Significant expenditures associated with
investments in real estate, such as maintenance costs, construction costs and debt payments, cannot generally be reduced if changes in market conditions cause a decrease in expected revenues from our properties. Moreover, the market value of home
inventories and undeveloped land can fluctuate significantly because of changing market conditions. As a result of these and other factors beyond our control, we may be forced to sell properties or land at a loss or for prices that generate lower
profit margins than we anticipate.

Determinations by INDECOPI may adversely affect our ability to enforce binding contracts

In resolving consumer protection complaints in the real estate and insurance sectors, INDECOPI has made determinations against real estate
developers resulting in the modification of contractual provisions applicable to purchasers, including one determination against Viva GyM, which we are currently challenging in court. Moreover, some purchasers of our real estate properties have
recently filed complaints against us before INDECOPI and/or made public claims through the media seeking to obtain compensation for alleged deficiencies in housing construction as well as the modification of the terms of their contracts, which may
have a negative impact on our real estate business. An increase in consumer complaints and consumer protective measures, particularly those resulting in the modification of contractual terms, may affect our ability to enforce our contracts under
their original terms if we are not able to counter such claims, which in turn may have a negative impact on our real estate business.

Additional Risks
Related to our Technical Services Business

Our engagements with clients may not be profitable or may be terminated or not renewed

The pricing and other terms of many of our client contracts in our technical services business necessarily require us to make estimates and
assumptions at the time we enter into these contracts that could differ from actual results. These estimates reflect our best judgments regarding the nature of the engagement and our expected costs to provide the contracted services. Because of the
competitive nature of the markets in which we operate, particularly in IT services, the risks related to errors in these estimates are heightened. Any increased or unexpected costs of unanticipated delays or complications in connection with the
performance of these engagements, including delays caused by factors outside our control, could make these contracts less profitable or not profitable, which would have an adverse effect on our profit margin. Our exposure to this risk increases
generally in proportion to the scope of services provided under a contract.

In addition, the success of our technical services business
is dependent on our ability to retain our clients. In our electricity networks services line of business in particular, Enel, which acquired Enersis (from whom we acquired control of the business in 2011) remains a key client; however, we cannot
assure you that they will continue to use our services in the future. Also, in our IT services business in particular, we may lose clients due to their conversion to in-house service providers. We are also
vulnerable to reduced volumes from our clients due to business downturns or for other reasons, which can reduce the scope and price of services we provide. A contract termination by a major client could cause us to experience a higher than expected
number of unassigned employees, which would affect our profitability until we are able to reduce or reallocate our personnel. We may not be able to replace any client that elects to terminate or not renew its contract with us, and the termination or
non-renewal of a significant number of our agreements, or of our most important contracts, may adversely affect our business and financial performance. In addition,
non-compliance on a contract with a public-sector client may lead to debarment from participating in government bidding processes and, consequently, inability to contract with other public-sector clients, not
just for the line of business where the alleged violation took place, but also for all of our other businesses.

We may not be successful in
obtaining new government contracts

We compete to provide services to the Peruvian government, and some of our competitors may have
greater financial and other resources or particular expertise pertinent to a specific contract. In addition, we may not be able to obtain additional government contracts for the provision of IT and electrical networks services, due to budget
constraints, policy changes or otherwise. Our inability to obtain new government contracts may adversely affect our business and financial performance.

We face risks related to the delivery of products and services by our suppliers

In the course of our IT services and electricity networks services, we depend on technology providers that may commit errors or omissions
related to the delivery or the quality of equipment, services or products that are essential to our business. A significant error or failure to deliver such equipment, products or services made by one of our suppliers, particularly in our IT
services business where we may have an exclusive arrangement with a specific supplier for a client, may adversely affect our business and financial performance.

##### Table of Contents

Our IT security measures may be breached or compromised and we may sustain system outages

We rely on encryption, authentication technology and firewalls to provide security for confidential information, including personal data,
transmitted to and by us over the internet. A breach of our network security measures could result in the misappropriation of proprietary or personal information or cause interruptions in our IT services or operations, could damage our reputation
and harm our ability to deliver services to our clients. This may result in client dissatisfaction and a loss of business. Our security measures may be inadequate to prevent security breaches, and we may be required to expand significant capital and
other resources to protect against the threat of security breaches and to alleviate problems caused by breaches as well as by any unplanned unavailability of our IT systems caused by other reasons, which may adversely affect our business and
financial performance.

Our services may infringe upon the intellectual property rights of others

Our IT services, or third-party products we offer our clients, may infringe the intellectual property rights of third parties, and we may have
infringement claims asserted against us. These claims may harm our reputation, increase our costs and prevent us from offering certain services or products. Any claims or litigation relating to intellectual property, even if ultimately decided in
our favor, could be time-consuming and costly, injure our reputation or require us to enter into royalty or licensing arrangements. Any limitation on our ability to provide a service or product could result in our loss of revenue-generating
opportunities and require us to incur additional expenses to develop new or modified solutions for future projects, which may adversely affect our business and financial performance.

Risks Relating to Peru

Economic, social and
political developments in Peru could adversely affect our business and financial performance

The substantial majority of our
operations are conducted in Peru and depend on economic and political developments in the country. As a result, our business may be materially and adversely affected by economic downturns, currency depreciation, inflation, interest rate fluctuation,
government policies, regulation, taxation, social instability, political unrest, terrorism and other developments in or affecting the country, over which we have no control. In the past, Peru has experienced periods of severe economic recession,
large currency devaluation and high inflation. We cannot assure you that Peru will not experience similar adverse economic developments in the future. In addition, Peru has experienced periods of political instability that has included a succession
of regimes with differing economic policies and programs. Previous governments have imposed controls on prices, exchange rates, local and foreign investments and international trade, restricted the ability of companies to dismiss employees,
expropriated private-sector assets and prohibited the remittance of profits to foreign investors. We cannot assure you that the Peruvian government will continue to pursue open-market policies that stimulate economic growth and social stability.

Moreover, investigations against former or current government officials relating to bribery payments made by Odebrecht have, and may
continue to, result in political uncertainty in Peru. On March 22, 2018, President Pedro Pablo Kuczynski presented his resignation, due to allegations of corruption for vote-buying in connection with the impeachment proceeding against him. On
March 23, 2018, the Congress accepted his resignation and his first vice president, Martín Vizcarra, was sworn in as acting president. We cannot assure you whether President Vizcarra will remain in office for the remainder of the
presidential term, which ends in July 2021. If President Vizcarra and the current second vice president both resign, the president of the Congress would become acting president and the Congress would call for new elections. The political instability
caused by these events could affect macroeconomic conditions in the country, including currency volatility, as well as have a negative effect on our business.

A separate criminal investigation and extradition order has been initiated against former President Alejandro Toledo. An investigation has
also been initiated against former President Ollanta Humala, who is currently being held by Peruvian authorities in preventive detention pending investigation.

Fluctuations in the value of the sol could adversely affect financial performance

Fluctuations in the value of the sol relative to the U.S. dollar could adversely affect Perus economy. In addition, fluctuations in the
value of the sol to the U.S. dollar can materially adversely affect our results of operations. In 2016, 46% and 33% of our revenues were denominated in soles and U.S. dollars, respectively, whereas 55% and 22% of our costs of sales were denominated
in soles and U.S. dollars, respectively. In the past, the exchange rate between the sol and the U.S. dollar has fluctuated significantly. We cannot assure you that the value of sol against other currencies will not fluctuate significantly in the
future, which could adversely affect the Peruvian economy and our business, financial condition and results of operations.



32

##### Table of Contents

In addition, although Peruvian law currently imposes no restrictions on the ability to convert
soles to foreign currency and transfer foreign currency outside of the country, in the 1980s and early 1990s, Peru imposed exchange controls, including controls affecting the remittance of dividends to foreign investors. We cannot assure you that
exchange controls in Peru will not be implemented in the future. The imposition of exchange controls could have an adverse effect on the economy and on your ability to receive dividends from us as a holder of ADSs.

Inflation could adversely affect our financial performance

In the past, Peru has suffered through periods of hyperinflation, which have materially undermined the Peruvian economy and the
governments ability to create conditions that support economic growth. A return to a high inflation environment would also undermine Perus foreign competitiveness, with negative effects on the level of economic activity and employment.

As a result of reforms initiated in the 1990s, Peruvian inflation decreased significantly from four-digit inflation during the 1980s. The
Peruvian economy experienced annual inflation of 2.6% in 2012, 2.9% in 2013, 3.2% in 2014, 4.4% in 2015, 3.2% in 2016 and 1.4% in 2017, as measured by the Peruvian Consumer Price Index (Índice de Precios al Consumidor del Perú).

If Peru experiences substantial inflation in the future, our costs of sales and administrative expenses could increase which could affect
our operating margins. Inflationary pressures may lead to governmental intervention in the economy, including the introduction of government policies that may adversely affect the overall performance of the Peruvian economy. For example, in response
to increased inflation, the Peruvian Central Bank, which sets the Peruvian basic interest rate, may increase or decrease the basic interest rate in an attempt to control inflation or foster economic growth.

Changes in tax laws may increase our tax burden and, as a result, negatively affect our financial performance

The Peruvian congress and government regularly implement changes to tax laws that may increase our tax burden. These changes may include
modifications in our tax rates and, on occasions, the enactment of temporary taxes that in some cases have become permanent taxes. Tax reforms related to the Peruvian income tax, value added tax and tax code have recently been approved, but we are
unable to estimate the impacts that these reforms may have on business. The effects of any tax reforms that could be proposed in the future and any other changes that result from the enactment of additional reforms have not been, and cannot be,
quantified. However, any changes to our tax regime may result in increases in our overall costs and/or our overall compliance costs, which could negatively affect our financial performance.

Earthquakes, severe weather and other natural disasters could adversely affect our business and financial performance

Peru is located in an area that experiences seismic activity and occasionally is affected by earthquakes. For example, in 2007, an earthquake
with a magnitude of 7.9 on the Richter scale struck the central coast of Peru, severally damaging the region south of Lima. Such conditions may result in physical damage to our properties and equipment, closure of one or more of our project sites
and infrastructure concessions, inadequate work forces in our markets and temporary disruptions in the supply of construction materials. In addition, Peru has also experienced adverse climate conditions (due to climate change or otherwise) and
adverse weather patterns, such as El Niño, an oceanic and atmospheric phenomenon that causes a warming of temperatures in the Pacific Ocean, resulting in heavy rains off the coast of Peru and potentially flooding. Poor weather conditions can
have significant adverse effects on our engineering and construction activities as well as on our operation and maintenance of infrastructure assets business. Any of these factors may materially adversely affect the Peruvian economy and our business
and financial performance.

A resurgence of terrorism in Peru could adversely affect the Peruvian economy and, as a result, our business and results
of operations

In the past, Peru experienced severe terrorist activity that reached its peak of violence against the government and
private sector in the late 1980s and early 1990s. In the mid-1990s, terrorist groups suffered significant defeats, including the arrest of leaders, resulting in considerable limitations in their activities.
Despite the suppression of terrorist activity, we cannot assure you that a resurgence of terrorism in Peru will not occur, or if there is such a resurgence, it will not disrupt the economy of Peru and our business.

The Peruvian economy could be affected by adverse economic developments in regional or global markets

Financial and securities markets in Peru are influenced, to varying degrees, by economic and market conditions in regional or global markets.
Although economic conditions vary from country to country, investors perceptions of events occurring in one country may adversely affect cash flows and securities from issuers in other countries, including Peru. For example, the Peruvian
economy was adversely affected by the political and economic events that occurred in several emerging economies in the 1990s, including in Mexico in 1994, the Asian crisis in 1997, the economic crisis in Russia in 1998, the Brazilian currency
devaluation in 1999 and the

##### Table of Contents

Argentine crisis in 2001, which affected the market value of securities issued by companies from markets throughout Latin America. In addition, Perus economy continues to be affected by
events in the economies of its major regional partners and in developed economies that are trading partners or that affect the global economy. The 2008-2009 global economic recession, principally driven by the subprime mortgage market in the United
States, substantially affected the international financial system, including Perus securities market and economy. More recently, global economic conditions, including slower growth in China, low global commodity prices, in particular oil and
gas prices, and the appreciation of the U.S. dollar against foreign currencies have generated economic uncertainty which may reduce the confidence of foreign investors, causing volatility in the securities markets and affecting the ability of
companies to obtain financing globally. The United Kingdom voted to exit the European Union on June 23, 2016. As of the date hereof, the actions to be taken by the United Kingdom to effectively exit the European Union and the duration of this
process are uncertain. The results of the referendum in the United Kingdom have caused, and are expected to continue to cause, volatility in financial markets, which in turn could have substantial adverse effects on our business, financial condition
and results of operations. On November 8, 2016, Mr. Donald J. Trump was elected president of the United States. President Trump has espoused an inclination to consider greater restrictions on free trade and limitations on immigration.
Changes in social, political, regulatory and economic conditions in the United States or in laws and policies governing foreign trade could create uncertainty in the international markets and could have a negative impact on emerging market
economies, including the Peruvian economy, which in turn could have a negative impact on our operations. The worsening of current global conditions or a new economic or financial crisis could affect Perus economy, and, consequently, materially
adversely affect our business and financial performance.

Risks relating to Chile, Colombia and other Latin American Countries

We face risks relating to our operations outside of Peru

Latin American economic, political and social conditions may adversely affect our business. Our financial performance may be significantly
affected not only by general economic, political and social conditions in Peru but also in other markets where we operate or intend to operate, including Chile and Colombia.

These countries have suffered significant economic, political and social crises in the past, and these events may occur again in the future.
We cannot predict whether changes in current administrations will result in changes in governmental policy and whether such changes will affect our business. Instability in the region has been caused by many different factors, including: significant
governmental influence over local economies; substantial fluctuations in economic growth; high levels of inflation; changes in currency values; exchange controls or restrictions on expatriation of earnings; high domestic interest rates; wage and
price controls; changes in governmental economic or tax policies, including retroactive changes; imposition of trade barriers, including import duties on information technology equipment; electricity rationing; liquidity of domestic capital and
lending markets; unexpected changes in regulation; expropriations; and high levels of organized crime, terrorism and social conflicts, as well as overall political, social and economic instability. More recently, tax and other governmental reforms
in Chile have led to concerns about potential negative effects on the Chilean economy, and the decline in global oil prices has also led to concerns about potential negative effects on the Colombian economy.

Risks Relating to our ADSs

We have identified
material weaknesses in our internal control over financial reporting, and if we cannot maintain effective internal controls or provide reliable financial and other information in the future, investors may lose confidence in the reliability of our
consolidated financial statements, which could result in a decrease in the value of our ADSs

Based on the assessment of our
internal control over financial reporting as of December 31, 2016, management has concluded that, as of such date, our internal control over financial reporting was not effective at the reasonable assurance level due to control deficiencies
that constituted material weaknesses. These material weaknesses consisted of:



| |  |  | Control Environment. An inconsistent and ineffective tone at the top was present under the then-existing senior management that was not effective to ensure adherence to IFRS and our accounting policies and
procedures. The control environment was not always sufficient to ensure adequate monitoring mechanisms were in place to secure that internal controls over financial reporting operated effectively. Personnel also lacked sufficient knowledge,
experience and training in these areas.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Risk Assessment. We identified deficiencies in the controls to address the risks of material misstatements, which contributed to deficiencies in controls with respect to: (i) certain business
processes, such as our period-end financial reporting process; (ii) the review, approval and documentation related to journal entries; (iii) the segregation of duties; (iv) timely accounting for
a signed contract relating to the construction consortium (Consorcio Constructor Ductos del Sur); (v) accounting for revenue and accounts receivable; (vi) inventory; and (vii) the review and approval of the valuation of acquired assets and
liabilities as part of a step acquisition.

| |  |  | Information and Communication. We identified deficiencies in the controls over information and communication.

| |  |  | Monitoring and Evidential Matter. We identified deficiencies in the monitoring controls related to the design and operational effectiveness of our internal controls.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------

These material weaknesses resulted in adjustments to the accounting for revenue and accounts receivable and a significant number of
adjustments and reclassifications in other accounts receivable owed to dismissed personnel, prepaid expenses, acquired assets and liabilities as part of a step acquisition, the classification calculation of the exchange gains/losses related to loans
with related entities, and intercompany transactions. Additionally, these material weaknesses could result in other misstatements in our financial results and disclosures, which could result in a material misstatement to our annual or interim
consolidated financial statements not being prevented or detected. Because of these material weaknesses, management concluded that we did not maintain effective internal control over financial reporting as of December 31, 2016, based on
criteria in Internal Control-Integrated Framework (2013) issued by the COSO.

For more information, see Item 15. Controls and
Procedures. A material weakness is a deficiency, or combination of deficiencies, in internal controls such that there is a reasonable possibility that a material misstatement in financial statements will not be prevented or
detected in a timely basis.

We are in the process of implementing measures to address these material weaknesses. We may not be able to
remediate these identified material weaknesses. Moreover, we may in the future discover other areas of our internal controls that have material weaknesses or that need improvement, particularly with respect to businesses that we acquire.

Any failure to maintain an effective internal control over financial reporting, or implement required new or improved controls, could harm our
operating results or cause us to fail to meet our reporting obligations. If we are unable to conclude that we have effective internal control over financial reporting, or if our independent registered public accounting firm is unable to provide us
with an unqualified opinion regarding the effectiveness of our internal control over financial reporting, investors could lose confidence in the reliability of our consolidated financial statements, which could result in a decrease in the value of
our ADSs.

The market price of our ADSs may fluctuate significantly, and you could lose all or part of your investment

Volatility in the market price of our ADSs may prevent you from being able to sell your ADSs at or above the price you paid for them. The
market price and liquidity of the market for our ADSs may be significantly affected by numerous factors, some of which are beyond our control and may not be directly related to our operating performance. These factors include, among others: actual
or anticipated changes in our results of operations, quarterly fluctuations, or failure to meet expectations of financial market analysts and investors; investor perceptions of our prospects or our industries; operating performance of companies
comparable to us and increased competition in our industries; new laws or regulations or new interpretations of laws and regulations applicable to our business; general economic trends in Peru; catastrophic events, such as earthquakes and other
natural disasters; and developments and perceptions of risks in Peru and in other countries.

Substantial sales of ADSs or common shares could cause
the price of our ADSs or common shares to decrease

Significant shareholders hold a large number of our common shares. These
securities are eligible for sale. The market price of our ADSs could decline significantly if we or our significant shareholders sell securities in our company or the market perceives that we or our significant shareholders intend to do so.

We may raise additional capital in the future through the issuance of equity securities, which may result in dilution of the interests of our
shareholders

We may need to raise additional capital and may opt for obtaining such capital through the public or private
placement of debt securities or securities convertible into our common shares. In the event of a public or private debt financing, or the financing through the issuance of securities convertible into our common shares, such additional funds may be
obtained with the exclusion of the preemptive rights of our shareholders, including the investors in our common shares, which may dilute the percentage interests of investors in our common shares.

No shareholder or group of shareholders holds a majority of our common shares

Our former chairman beneficially owns 17.81% of our outstanding share capital. No shareholder or group of shareholders currently owns a
majority of our common shares. In addition, there is no shareholders agreement among any of our significant shareholders. Accordingly, no shareholder or group of shareholders may on its own determine the outcome of substantially all matters

submitted for a vote to our shareholders. In addition, a new investor or group of investors may in the future seek to acquire a significant stake in, or control of, our company, subject to
compliance with Peruvian tender offer requirements which require that a tender offer be made to all shareholders upon, among other matters, acquisition of 25%, 50% and 60% of our voting rights. If a new investor or group of investors acquires a
significant stake in, or control of, our company, we cannot assure you that such investor or group of investors will not seek to change how our business is managed.

Holders of ADSs may be unable to exercise voting rights with respect to our common shares underlying the ADSs at our shareholders meetings

As a holder of ADSs representing common shares being held by the depositary in your name, you may exercise voting rights with
respect to the common shares represented by the ADSs only in accordance with the deposit agreement relating to the ADSs. Holders of our common shares will receive notice of shareholders meetings through publication of a notice 25 days in
advance, in accordance with Peruvian law, in the official gazette in Peru, a Peruvian newspaper of general circulation and the website of the Peruvian Securities Commission, and will be able to exercise their voting rights by either attending the
meeting in person or voting by proxy. ADS holders will not receive notice directly from us. Instead, pursuant to the deposit agreement, we will notify the depositary, who will mail to holders of ADSs the notice of the meeting and a statement as to
the manner in which voting instructions may be given. To exercise their voting rights, ADS holders must instruct the depositary how to exercise the voting rights for the common shares which underlie their ADSs. Due to these additional procedural
steps involving the depositary, the process for exercising voting rights may take longer for ADS holders than for holders of our common shares.

Holders of ADSs also may not receive voting materials in time to instruct the depositary to vote the common shares underlying their ADSs. In
addition, the depositary and its agents are not responsible for failing to carry out voting instructions of the holders of ADS or for the manner of carrying out such instructions, unless such failure can be attributed to gross negligence, bad faith
or willful misconduct on the part of the depositary or its agents. Accordingly, holders of ADSs may not be able to exercise voting rights, and they will have little, if any, recourse if the underlying common shares are not voted as requested.

Our shareholders ability to receive cash dividends may be limited

Our shareholders ability to receive cash dividends may be limited by the ability of the depositary to convert cash dividends paid in
soles into U.S. dollars. Under the terms of our deposit agreement with the depositary for the ADSs, the depositary will convert any cash dividend or other cash distribution we pay on the common shares underlying the ADSs into U.S. dollars, if it can
do so on a reasonable basis and can transfer the U.S. dollars to the United States. If this conversion is not possible or if any government approval is needed and cannot be obtained, the deposit agreement allows the depositary to distribute the
foreign currency only to those ADR holders to whom it is possible to do so. If the exchange rate fluctuates significantly during a time when the depositary cannot convert the foreign currency, you may lose some or all of the value of the dividend
distribution.

Holders of ADSs may be unable to exercise preemptive or accretion rights with respect to the common shares underlying their ADSs

Under Peruvian corporate law, if we issue new common shares as part of a capital increase, unless otherwise agreed to by holders
of 40% of our subscribed voting common shares and, provided that such capital increase does not favor, directly or indirectly, certain shareholders to the detriment of others, our shareholders will generally have the right to subscribe to a
proportional number of common shares of the class held by them to maintain their existing ownership percentage, which is known as preemptive rights. In addition, shareholders are entitled to the right to subscribe for the unsubscribed common shares
at the end of a preemptive rights offering, on a pro rata basis, which is known as accretion rights. You may not be able to exercise the preemptive or accretion rights relating to common shares underlying your ADSs unless a registration statement
under the Securities Act is effective with respect to those rights or an exemption from the registration requirements of the Securities Act is available. We are not obligated to file a registration statement with respect to the common shares
relating to these preemptive and accretion rights, and we cannot assure you that we will file any such registration statement. Unless we file a registration statement or an exemption from registration is available, you may receive only the net
proceeds from the sale of your preemptive and accretion rights by the depositary or, if the preemptive and accretion rights cannot be sold, they will be allowed to lapse. As a result, U.S. holders of our ADSs may suffer dilution of their interest in
our company upon future capital increases.

We are entitled to amend the deposit agreement and to change the rights of ADS holders under the terms
of such agreement without the prior consent of the ADS holders

We are entitled to amend the deposit agreement and to change the
rights of the ADS holders under the terms of such agreement without the prior consent of the ADS holders. Any change related to an increase in deposits or charges for book-entry securities services or any modification that might hinder the rights of
the ADS holders will be effective within 30 days after the ADS holders have received notice of such change or modification and such holders will have no right to any compensation whatsoever.

Peru has different corporate disclosure and accounting standards than those you may be familiar with in the
United States

Financial reporting and securities disclosure requirements in Peru differ in certain significant respects from those
required in the United States. There are also material differences among IFRS, Peruvian GAAP and U.S. GAAP. Accordingly, the information about us available to you will not be the same as the information available to holders of shares issued by a
U.S. company. In addition, the Peruvian Securities Market Law, which governs open or publicly listed companies, such as us, imposes disclosure requirements that are more limited than those in the U.S. in certain important respects. Although Peruvian
law imposes restrictions on insider trading and price manipulation, applicable Peruvian laws are different from those in the United States, and the Peruvian securities markets are not as highly regulated and supervised as the U.S. securities
markets.

Our status as a foreign private issuer allows us to follow alternate standards to the corporate governance standards of the New York Stock
Exchange, which may limit the protections afforded to investors

We are a foreign private issuer within the meaning of the New York
Stock Exchange corporate governance standards. Under New York Stock Exchange rules, a foreign private issuer may elect to comply with the practices of its home country and not to comply with certain corporate governance requirements applicable to
U.S. companies with securities listed on the exchange. We currently follow certain Peruvian practices concerning corporate governance and intend to continue to do so. Accordingly, holders of our ADSs will not have the same protections afforded to
shareholders of companies that are subject to all New York Stock Exchange corporate governance requirements.

For example, the New York
Stock Exchange listing standards provide that the board of directors of a U.S. listed company must have a majority of independent directors at the time the company ceases to be a controlled company. Under Peruvian corporate governance
practices, a Peruvian company is not required to have a majority of independent members on its board of directors. The listing standards for the New York Stock Exchange also require that U.S. listed companies, at the time they cease to be
controlled companies, have a nominating/corporate governance committee and a compensation committee (in addition to an audit committee). Each of these committees must consist solely of independent directors and must have a written
charter that addresses certain matters specified in the listing standards. Under Peruvian law, a Peruvian company may, but is not required to, form special governance committees, which may be composed partially or entirely of non-independent directors. In addition, New York Stock Exchange rules require the independent non-executive directors of U.S. listed companies to meet on a regular basis
without management being present. There is no similar requirement under Peruvian law.

The New York Stock Exchanges listing
standards also require U.S. listed companies to adopt and disclose corporate governance guidelines. In July 2002, the Peruvian Securities Commission and a committee comprised of regulatory agencies and associations prepared and published a list of
suggested non-mandatory corporate governance guidelines called the Principles of Good Governance for Peruvian Companies. Although we have implemented these measures, we are not legally required to
comply with the corporate governance guidelines, only disclose whether or not we are in compliance.

Minority shareholders in Peru are not afforded
equivalent protections as minority shareholders in other jurisdictions and investors may face difficulties in commencing judicial and arbitration proceedings against our company or the controlling shareholder

Our company is organized and existing under the laws of Peru. Accordingly, investors may face difficulties in serving process on our company,
officers and directors or significant shareholders in the United States of certain other jurisdictions, and in enforcing decisions granted by courts located in other jurisdictions against our company, our officers and directors or significant
shareholders that are based on securities laws of jurisdictions other than Peru.

In Peru, there are no proceedings to file class action
suits or shareholder derivative actions with respect to issues arising between minority shareholders and an issuer, its controlling shareholders or directors and officers. Furthermore, the procedural requirements to file actions by shareholders
differ from those of other jurisdictions, such as in the United States. As a result, it may be more difficult for our minority shareholders to enforce their rights against us, our directors, officers or significant shareholders as compared to the
shareholders of a U.S. company. The deposit agreement provides that the depositary has no obligation to commence or become involved in any judicial proceedings and any other legal actions relating to the ADSs or the deposit agreement, either on
behalf of the ADS holders or on behalf of any other person.

Judgments of Peruvian courts with respect to our common shares will be payable only in
soles

If proceedings are brought in the courts of Peru seeking to enforce our obligations in respect of the common shares, we will
not be required to discharge our obligations in a currency other than soles. Under Peruvian exchange control limitations, an obligation in Peru to pay amounts denominated in a currency other than soles may be satisfied in Peruvian currency only at
the exchange rate, as determined by the Peruvian Central Bank, in effect on the date the judgment is obtained, and such amounts are then adjusted to reflect exchange rate variations through the effective payment date. The then prevailing exchange
rate may not afford non-Peruvian investors with full compensation for any claim arising out of or related to our obligations under the ADSs.

If securities or industry analysts publish unfavorable research about our business or if they cease to
follow our business, the price and trading volume of the ADSs could decline

The trading market for the ADSs will depend, in part,
on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who covers us downgrades the ADSs or publishes unfavorable research about our business, the price of the ADSs would
likely decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, demand for the ADSs could decrease, which could cause the price and trading volume of the ADSs to decline.

B. Business Overview

Overview

We are the largest engineering
and construction company in Peru as measured by revenues during 2016, and one of the largest publicly-traded engineering and construction company in Latin America as measured by market capitalization as of December 31, 2016, with strong
complementary businesses in infrastructure, real estate and technical services.

With more than 80 years of operations, we have a long
track record of successfully completing the engineering and construction of many of Perus landmark private- and public-sector infrastructure projects, such as the Lima International Airport and the Peru LNG gas liquefaction plant, and we
believe we have earned a reputation for operational excellence in our markets. We have developed a highly-experienced management team, a talented pool of more than 2,900 engineers and a skilled work force that share our core corporate values of
quality, professionalism, reliability and efficiency. As a company listed on the Lima Stock Exchange since 1997 and the New York Stock Exchange since 2013, we also abide by the highest corporate governance standards in Peru.

Beginning in the mid-1980s, we leveraged our engineering and construction expertise into complementary
lines of business, such as the development, ownership, operation and maintenance of infrastructure assets (including the Lima Metro, Perus only urban railway system), real estate development, and the provision of technical services primarily
to infrastructure-related assets. We believe our business mix creates significant opportunities across our lines of business, generates more stable revenues and earnings on a consolidated basis, and provides additional financial stability to our
company.

##### Table of Contents

As a result of our performance in Peru, we have been requested by clients to undertake the
engineering and construction of large and complex projects outside our home market, such as the Pueblo Viejo gold mine for Barrick Gold in the Dominican Republic. Through the successful execution of those projects, we have developed operational
experience in other Latin American countries. We have further expanded our activities in other key markets of the region through the acquisition of businesses with solid positions in those markets. In February 2011, we acquired a controlling
interest in Compañía Americana de Multiservicios (CAM), which is headquartered in Chile and provides technical services to power utility companies in Chile, Peru and Colombia. In October 2012, we acquired a controlling interest in Vial
y Vives, an engineering and construction company specializing in the Chilean mining sector, and in August 2013, we acquired a controlling interest in DSD Construcciones y Montajes, a Chilean engineering and construction company specialized in
providing services to the energy, oil and gas, cellulose and mining sectors in Chile and Latin America. In December 2014, we acquired a controlling interest in Morelco, an engineering and construction company specialized in the Colombian oil and gas
and other energy sectors.

The tables below show our backlog, revenues and EBITDA from 2012 to 2016.



|                             |  |                               |  |

|Backlog (in millions of US$) |  | Revenues (in millions of S/.) |  | EBITDA (in millions of S/.)
|LOGO                        

During 2016, we generated revenues of S/.6,469.6 million (US$1,925.5 million), EBITDA of
S/.(64.4) million (US$(19.2) million), and net profit of S/.(451.6) million (US$(134.4) million) including net profit attributable to controlling interest of S/.(509.7) million (US$(151.7) million).

Our Strengths

We believe our
companys strengths provide us with significant competitive advantages. Our principal strengths include the following:

Leader in growing
markets

We are the largest engineering and construction company in Peru as measured by revenues during 2016, and one of the
largest publicly-traded engineering and construction company in Latin America as measured by market capitalization as of December 31, 2016. Peru is undergoing a period of development, with over 4.3% average annual real GDP growth between 2009
and 2017 and significant private and public investments in the mining, power, oil and gas, transportation, real estate and other infrastructure sectors. We have completed some of the most complex and large-scale infrastructure projects in the
country, and we believe we are an integral part of Perus ongoing transformation with projects that contribute to the overall economic development of the country. We believe our expertise, reputation, scale and operational capabilities in Peru
position us to take advantage of the countrys favorable economic conditions and growth opportunities. We believe we are also a significant infrastructure concessionaire in Peru, a large apartment building developer in Peru, and a leading IT
company in Peru.

We believe we are well-positioned to leverage our platform in the Peruvian market to continue to grow our business in
other countries in Latin America, primarily Chile and Colombia. Throughout our history, we have undertaken complex E&C projects in the region and have recently completed acquisitions in Chile and Colombia. Moreover, we believe we are one of the
leading mining E&C companies in Latin America.

Long-standing track record and reputation for operational excellence

During our more than 80-year history, we have focused on the successful and on-time execution of complex projects, through our deliver before deadline and lean construction initiatives. Our extensive experience has allowed us to gain deep market knowledge and
expertise, which help us better serve our clients and manage risks in our contractual arrangements. We believe we have a reputation for operational excellence, and were named among the 10 most admired companies in Peru through a survey

##### Table of Contents

conducted by PwC in 2012, 2013, 2014, 2015 and 2016. In addition, Merco ranked us seventh out of 100 companies with the best reputations in Peru in 2012, 2013, 2014, 2015 and 2016. We believe
that our track record and the reputation we have earned in our markets for operational excellence are key factors in winning new and repeat business, as well as in partnering with strategic industry players and attracting top talent to our company.

Complementary lines of business which generate more stable cash flows and create additional business opportunities across our segments

We have expanded our company by developing complementary lines of business, many of which have become leaders in their respective markets.
These lines of business create significant business opportunities across our segments, enabling us to capture a greater share of infrastructure spending, and also generate cost synergies. One example is Norvial, a toll-road concession operated
within our Infrastructure segment. In addition to managing the concession, we used our E&C segment to design and construct the expansion of the highway and, once constructed, we are now using our Technical Services segment to operate and
maintain the highway. In addition to increasing our levels of consolidated activity, many of these lines of business enable us to achieve more stable cash flows through medium and long-term client service contracts and concessions, which counter in
part the cyclicality of the engineering and construction business.

Significant backlog

Our backlog amounted to US$3,137.4 million as of December 31, 2016. We believe that our backlog, which as of December 31, 2016
represented approximately 1.6x of our related 2016 revenues, provides visibility as to our potential for growth in the coming years, although backlog may not always be an accurate indicator of future revenues. See Item 3.D. Key
InformationRisk FactorsRisks Related to our CompanyOur backlog and our ratio of historical backlog to revenues may not be reliable indicators of future revenues or profit. Moreover, we believe our backlog is strategically
targeted to our key end-markets such as mining, infrastructure, power, energy and real estate. Approximately, 75.8% of our backlog as of December 31, 2016 is comprised of contracts with the private
sector. Furthermore, we continuously evaluate bidding on contracts arising from the significant ongoing private and public investments in Latin America.

Proven ability to create and grow businesses organically and through acquisitions

We have proven our ability to extend our engineering and construction capabilities into complementary lines of business in a diverse range of
industries, some of which began as innovative start-ups in response to client needs. For example, in 1984, we created a new IT business division, which grew and evolved through the years to become the second
largest IT company in Peru. Additionally, we also have successfully acquired and integrated new businesses. In February 2011, we acquired a controlling interest in CAM, our electricity services business headquartered in Santiago, Chile, and have
integrated its operations and personnel into our company, while improving its operational performance. In October 2012, we acquired Vial y Vives, an engineering and construction company specializing in the Chilean mining sector which complements our
leading E&C practice in the mining sector. In August 2013, we acquired a controlling interest in DSD Construcciones y Montajes, a Chilean engineering and construction company whose main focus is electromechanical works and assemblies in
construction projects related to oil refineries, pulp and paper, power plants and mining plants. More recently, in December 2014 we acquired a controlling interest in Morelco, an engineering and construction company specialized in the Colombian oil
and gas and other energy sectors. We believe that our proven ability to create new businesses, develop businesses organically and acquire and successfully integrate new businesses into our platform is a key competitive advantage to expand our
operations in Latin America.

Highly experienced management, talented engineers and skilled workforce, with shared core corporate values

We motivate our management through performance-based compensation, which align their interests with those of our shareholders. In
addition, through our efforts to attract, train and retain our workforce, we have built a talented team of employees, including more than 2,900 engineers. We also have access to a network of approximately 156,000 manual laborers throughout Peru that
can supplement our workforce when required by our construction pipeline. Thanks to our extensive and talented team, we have the capability and scale to undertake large and complex projects in Peru and elsewhere.

We have developed a strong corporate culture based on principles of high-quality, professionalism, reliability and efficiency. We safeguard
the health and safety of our collaborators and of all the persons participating in our operations and services. To that end, we provide safe work conditions, we manage risks in a timely manner and we promote a culture of prevention, starting from
the leadership and commitment of our senior management. In 2016, we had an accident incidence rate of 0.4, calculated over 86,303.933 hours worked.

Our Strategies

In response to the impact of our association with Odebrecht in certain projects in Peru and the termination of the GSP pipeline concession, we
are implementing a strategic action plan, as described in Item 5.A. Operating and Financial Review and ProspectsOperating ResultsRecent Developments.

Our vision is to be the most reliable engineering services company in Latin America. Our key long-term strategies to achieve this
vision include the following:

Be the contractor of choice for large-scale and complex projects in Peru and other key Latin American markets

We intend to enhance our position as a contractor of choice for large-scale and complex infrastructure projects in Peru and other
key Latin American markets, by (i) utilizing the scale, expertise and market knowledge we have accumulated during our more than 80-year operating history to strengthen and expand our E&C segment;
(ii) maintaining and further developing our long-standing client relationships based on our ongoing pursuit of operational excellence; (iii) continuing to strategically partner with global industry leaders, such as Bechtel and Fluor, with
complementary capabilities for specific projects that we undertake; and (iv) leveraging our expertise in the mining sector with a view to becoming the premier mining services provider throughout Latin America.

Maintain highly capitalized balance sheet

We seek to maintain a prudent and sustainable capital structure and a strong financial position to allow us to capitalize on additional
business opportunities as they arise. With the renegotiation and eventual repayment of debt related to GSP, we intend to regain our financially disciplined approach by significantly limiting our debt incurrence to identified projects with repayment
sources.

Continue fostering our core corporate values throughout the organization

We will continue to instill our core corporate values throughout our organization, while also transmitting these values to surrounding
communities. We will continue to attract and develop our human capital through various training, mentorship and reward programs in order to maintain our position as the best company in Peru to learn and work in the engineering and construction
field. We also seek to promote social welfare by fostering relationships with the communities that surround our areas of operation. We strive to promote our corporate values to strengthen our organization and improve our performance as well as to
have a positive impact on the markets where we operate.

2016 E&C Revenues by End-Market



LOGO

We mainly undertake private-sector projects, particularly projects with a high degree of complexity, which
enable us to develop innovative and tailor-made solutions to our clients. We provide our clients with an integral service offering by leveraging our various areas of expertise and engaging in virtually all aspects of project execution, thereby
capturing a larger share of investment projects.

In 1999, we began adopting the lean construction philosophy as a pillar in
our design and construction projects. Lean construction aims to create value for customers by better understanding and considering clients needs to improve project design, functionality and cost optimization. Lean
construction also provides techniques and tools that significantly reduce construction waste by improving planning reliability, process design, coordination and collaboration.

Although we primarily undertake engineering and construction projects in Peru, our clients often ask us to undertake the engineering and
construction of large and complex projects in other countries, such as Mexico, the Dominican Republic, Bolivia, Panama and Chile. As a result, we have developed extensive experience executing projects throughout Latin America. To further capitalize
on our capabilities and expertise, we have decided to expand our activities into other key markets, such as Chile and Colombia, which have been benefitting from high levels of investment and are aligned with our areas of strategic focus. In 2016,
approximately US$254 million (S/.853.4 million) of our E&C revenues were derived from international projects outside of Peru.

The acquisition of Vial y Vives  DSD has solidified our presence in Chile. While we have been undertaking projects in Chile since 1995,
such as the construction of the transmission line and crusher of the Caserones mine for SCM Minera Lumina Copiapo, we believe we will benefit from the established and long-lasting presence in the country of both Vial y Vives and DSD Construcciones y
Montajes. Moreover, through the acquisition in December 2014 of Morelco, an engineering and construction company focused on the oil and gas and other energy sectors, we established our presence in the Colombian market.

Given the prevalence of mining operations in our principal marketsPeru has projected investment flows of approximately
US$41 billion between 2016 and 2021 and Chile as projected investment flows of approximately US$49 billion between 2016 and 2025, according to the Lima Chamber of Commerce and Cochilco, respectivelywe have significant expertise with
respect to specialized engineering and construction services for the mining sector. As a result, we believe we are one of the leading mining construction companies in Latin America and we leverage this expertise both within our principal markets as
well as to selectively undertake complex projects across the region.

The table below sets forth selected financial information for our
E&C business segment.

Clients

We believe that we have developed long-term relationships with many clients as a result of our performance over the years and are
focused on the successful and on-time execution of complex projects through our deliver before deadline and lean construction initiatives. Our extensive experience has earned us a
reputation for operational excellence and allowed us to gain deep market knowledge and expertise, which help us better serve our clients. The principal clients of our E&C segment include renowned domestic and multinational mining, power, oil and
gas, transportation and infrastructure development companies, such as Glencore, Sociedad Minera Cerro Verde, Guyana Goldfields, Luz Del Sur, Kallpa Generación, Samsung Engineering, Rio Alto, Chinalco Mining, Hudbay Minerals and Red Eagle
Mining Corporation, among others. We have a well-diversified client base, as none of our engineering and construction clients accounted for 8% or more of our consolidated revenues in 2016.

Project Selection and Bidding

We
win new engineering and construction contracts through public bidding processes or direct negotiation from a variety of sources, including potential client requests, proposals from existing or former clients, opportunities sought by our commercial
team and from requests by the Peruvian government. Approximately 89% of our 2016 revenues came from private-sector contracts. The Peruvian government and its agencies typically award construction contracts through a public bidding process conducted
in accordance with the Peruvian State Contracting Law (Ley de Contrataciones del Estado). In the private sector, in addition to obtaining new projects, another important source of revenue involves increases in the scope of work to be
performed in connection with already existing projects. These arrangements are typically negotiated directly with the client, often during the course of the work we are already performing for that client.

We have a designated team that oversees the management of project proposals and a commercial team that reviews and evaluates potential
projects in order to estimate costs. In considering whether to bid for a potential project, we principally consider the following factors: competition and the probability of being awarded the project; project size; the client; our experience
undertaking similar projects; and the availability of resources, including human resources. As part of the project selection process, our commercial team performs a detailed cost analysis utilizing sophisticated software we developed to assist in
determining whether the project is viable and cost-effective. If we choose to pursue a project, a budget leader is assigned to prepare the offer that is eventually presented to our potential client.

Despite the budgeting risks generally associated with engineering and construction contracts, our management believes that our experience
generally allows us to estimate our project costs accurately. Our project management teams also periodically review project budgets for inconsistencies between budgeted and actual costs in order to recover for cost variations through contract
renegotiation. Budgeting risks are also mitigated through advance payments. Considering that we receive advance payments for most of our E&C contracts, our E&C projects typically do not require significant working capital investment. Our
E&C segment secures financing primarily to purchase machinery and equipment for our construction and contract mining services.

##### Table of Contents

We are required, in the majority of our construction contracts, to provide a performance bond to
guarantee project performance and completion, which remain in effect for the contracts duration. We are also required to provide performance bonds to secure any advance payments provided to us by our clients. These bonds are periodically
reduced during the projects execution in accordance with project advancement. After the expiration of the contract term, we are typically required to provide an additional performance bond that remains valid for one year.

Contracts

We principally enter
into four types of engineering and construction contracts:



| |  |  | Cost-plus fee contracts. The contract price is based upon actual costs incurred for time and materials plus a fee, which may be a percentage of the costs incurred or a
pre-determined fee. Sometimes, cost-plus fee contracts include a target price, and a contractual arrangement that determines our responsibility in the event the total cost of the project exceeds the target
price or the benefit we receive if the total contract price results in cost savings. Cost-plus fee contracts tend to involve the least budgeting risk for us.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Unit price contracts. The contract price is based upon a price per unit (i.e., variable quantities of work priced at defined unit rates). Each line item of the project budget, such as cubic meter of earth
excavated or cubic meter of concrete poured, has a defined price, but the quantities of the units may vary. Our bid price reflects our estimate of the costs that we expect to incur for each work unit. These contracts typically include an
escalation clause which is essentially an adjustment mechanism to account for Peruvian inflation.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Lump-sum contracts. The contract price is fixed. Our bid is meant to cover all costs and include a profit. The principal risk in these types of contracts are errors
in calculating our costs, including those of raw materials; miscalculation of the number of units or workers needed to complete the project; unanticipated technical complexities; or other unexpected events or circumstances that may increase our

| |  |  | Engineering, procurement and construction (EPC) contracts. EPC contracts, known as single source or turn-key contracts, are also lump-sum contracts. Pursuant to EPC contracts, we provide a broad range of basic and detailed engineering services, including preparation of the technical project specifications, detailed drawings and construction
specifications; technical studies; and identification of lists of materials and equipment necessary for the project. These contracts, which we utilize predominantly for our mining contracts, require a high-level of expertise and generally involve
the most budgetary risks for us.

Raw Materials

The principal inputs we use in our E&C segment are, among others, fuel, cement and steel. These and the other products we require in our
E&C segment may be subject to the availability of raw materials, such as oil and iron, and commodity pricing fluctuations, which we monitor on a regular basis. We typically aim to enter into master supply agreements for a period of six months to
one year. Although we obtain the majority of our inputs needs in Peru, we believe we have access to numerous global supply sources. The availability of these inputs, however, may vary significantly from year to year due to various factors including
client demand, producer capacity, market conditions, transport costs and specific material shortages, and we may incur additional costs in obtaining them.

We purchase and lease the equipment we require for our E&C segment business from several local and international suppliers, currently with
no significant concentration with any particular suppliers. While we do not have difficulty obtaining the equipment we need, we may face difficulties finding skilled personnel who are able to operate certain equipment and machinery.

Competition

We generally compete
with some of the largest contractors in Peru and the other countries where we operate. Because the E&C sector is highly competitive, the markets served by our business generally require substantial resources and highly-skilled and experienced
technical personnel. The principal competitors of our E&C segment include local companies such as Besalco Cosapi S.A., San Martin Contratistas Generales, ICCGSA, JJC Contratistas Generales S.A., and international companies such as Techint
S.A.C., SSK Montajes e Instalaciones S.A.C., Skanska del Perú S.A., Mota-Engil Peru S.A., Salfacorp S.A., OHL, Acciona, Astaldi, Grupo FCC, Ismocol, Termotecnica, Masa, Thiess, Redpath, among others. For certain projects, due to the size of
the project, expertise required and other factors, we may choose to partner with our competitors, including the aforementioned companies.

Competition for our E&C segment is driven by performance, skill and project execution
capabilities for completing complex projects in a safe, timely and cost-efficient manner, as well as price.

Infrastructure

We are an important toll road concessionaire in Peru, operating three toll roads. Moreover, we are the concessionaire for the Lima Metro, the
largest mass-transit rail system in Peru, and a waste water treatment plant. Additionally, we operate 10 multiple fuel storage facilities, four producing oil fields under long-term government contracts and we own a gas processing plant.

The table below sets forth selected financial information for our Infrastructure business segment.

Our strategy is to pursue concessions with the potential to generate
business opportunities across our organization. Once we obtain a concession, our goal is to be involved virtually in all aspects of project execution through the participation of our different business segments, from the design and construction to
the operation and maintenance of the infrastructure asset.

Through our Infrastructure segment we participate in a number of joint
operations with the objective of bidding for government concessions or other long-term contracts. When bidding, we occasionally look for partners to reduce our risks and achieve the level of expertise needed to meet the demands of each particular
project.

The following table shows selected information about our current concessions and long-term contracts as of December 31,
2016.

Additionally, the Chavimochic concession was awarded in 2013 for the design, construction, operation and maintenance of major hydraulic works
in northern Peru. Affiliates of Odebrecht own 73.5% of the Chavimochic consortium, with the remaining 26.5% stake held by us. The second phase of the hydraulic works project has not begun as a result of the governments failure to deliver the
required lands for the project. Chavimochic has requested the termination of the concession in light of the governments breach, and the parties are currently in discussions, including for a potential sale of the project to the government.

On November 11, 2013, we entered into a memorandum of understanding with Canada Pension Plan Investment Board (CPPIB), to
create an alliance regarding a partnership to invest in infrastructure projects in Latin America, mainly Peru, Chile and Colombia. This alliance is non-exclusive and investments will be determined on a case-by-case basis. In December 2014, we undertook our first large investment with CPPIB, by formalizing an agreement with Enagás (as defined below) and CPPIB whereby
we acquired 51% of Tecgas and owner of 100% of the shares of COGA, the current operator of TGP while Enagás acquired 30% and CPPIB maintained 19% of the participation. COGA is dedicated to the management, operation, maintenance, and integrity
management of transport and distribution hydrocarbon pipelines and installations as well as industrial plants and ancillary installations. COGA operates and maintains more than 1,430km of pipelines, one compression plant with 72,000 horse power and
four pump stations with 19,200 horse power each. COGA operates two pipelines: one which is 730 km and transports natural gas (GN) with a 1,275 MM cubic feet per day capacity; and the other one which is 530 km and transports natural gas liquids (NGL)
with a 130,000 barrels per day capacity. Both pipelines run from Cusco to Ayacucho and Huancavelica, with the GN pipeline extending to Lurin and the NGL pipeline continuing to the Pisco fractionation plant. As this is a joint operation, we do not
include the results of our COGA venture in our consolidated results under our Infrastructure segment. On April 24, 2017, we sold our interest in COGA.

On September 29, 2015, we entered into a memorandum of understanding with Odebrecht Latinvest to participate with a 20% stake in the
shareholder equity of Concesionaria Gasoducto Sur Peruano S.A., for an amount of US$215 million (S/.722.4 million). The other shareholders are Odebrecht Latinvest with a 55% stake and Enagás with a 25% stake. Concesionaria Gasoducto Sur
Peruano S.A. was responsible for the design, financing, construction and operation of the southern gas pipeline, a project which would bring natural gas to the southern region of Peru, particularly to the provinces of Cuzco, Arequipa, Puno and
Moquegua. The GSP gas pipeline concession was terminated by the Peruvian Ministry of Energy and Mines on January 24, 2017.

Infrastructure Lines of Business

Toll Roads

Perus economic development is underpinned by a strong government commitment to infrastructure investment, with a particular focus on
improving the countrys road system through the award of new concessions to the private sector. We believe this commitment offers significant opportunities to our Infrastructure segment.

##### Table of Contents

Our Infrastructure segment currently has three toll road concessions through our subsidiaries
Norvial, Survial and Canchaque. All three toll roads are currently in operation and we have the authorizations, permits and licenses necessary to fulfill our obligations under each concession, including releases of rights of way. All of our toll
road concessions have utilized the construction services of our E&C segment and the roads are currently operated and maintained by our Technical Services segment. The table below sets forth selected financial information relating to our toll
roads.

Norvial

Under our Norvial concession, we operate and maintain part of the only major highway that connects Lima to the northwest of Peru. This 183-km road, known as Red Vial 5, runs from the cities of Ancón to Pativilca and has three toll stations. The concession was awarded to Norvial in 2003 for a 25-year
term. We own 67% of Norvial; and our partner in this concession is JJC Contratistas Generales. The following map shows the location of the Red Vial 5 road in Peru.

Norvials revenue derives from the collection of tolls. For the Norvial toll road, the toll rate is
set out in the Norvial concession agreement and adjusted in accordance with a contractual formula that takes into account the sol/U.S. dollar exchange rate and Peruvian and U.S. inflation. We are required to transfer 5.5% of our monthly toll revenue
to the Peruvian Ministry of Transport and Communications and pay a 1% regulatory fee to the Peruvian Supervisory Agency for Investment in Public Transportation Infrastructure.

Our obligations under the concession include expanding the already existing road by, among other things, adding two additional lanes. The
first stage of construction was completed in 2008, and the second stage commenced in the second quarter of 2014 and is expected to be completed by March 2019. We estimate that our capital investment for the second stage will be approximately
US$95 million (S/.319.2 million).

Unlike other toll roads in Peru, Norvial charges toll fees in both directions. Our
road is highly transited both by heavy vehicles, primarily for the purpose of transporting goods, and also by passenger vehicles, which typically use the road to access tourist destinations. The following table sets forth average daily traffic
volume and average toll fees charged for vehicle equivalents in respect to the Norvial toll road concession for 2014, 2015 and 2016.

Survial

Under our Survial concession, we operate and maintain a 750 km road from the San Juan de Marcona port to Urcos, Peru, which is connected to an
interoceanic road that runs up to the Peruvian-Brazilian border. The road has five toll stations and three weigh stations. The concession was awarded to Survial in 2007 for a
25-year term. We own 99.9% of Survial. The following map shows the location of the road in Peru.



LOGO

Our obligations under the concession include the construction of the road, which was completed in 2010.

Our revenue from this concession consists of an annual fee paid to Survial by the Peruvian Ministry of Transport and Communications in
consideration for the operation and maintenance of the road, which fee can vary depending on the amount of maintenance required due to road damages. In 2014, 2015 and 2016 the fee amounted to US$8.9 million (S/.26.6 million),
US$33.9 million (S/.115.7 million) and US$8.1 million (S/.27.2 million), respectively. Our revenue in this concession does not depend on traffic volume.

Canchaque

Under our Canchaque concession, we
operate and maintain a 78 km road from the towns of Buenos Aires to Canchaque, in Peru. The road has one toll station. The concession was awarded to Canchaque in 2006 for a 15-year term. We own 99.9% of
Canchaque. Our obligations under the concession include the construction of the road, which was completed in 2009. Our revenue from this concession consists of an annual fee paid by the Peruvian Ministry of Transport and Communications in
consideration for the operation and maintenance of the road, which fee can vary depending on the amount of road maintenance required due to road wear and tear. In 2014, 2015 and 2016, the fee amounted to US$1.4 million (S/.4.2 million),
US$1.3 million (S/.4.4 million) and US$1.2 million (S/.4.0 million), respectively. Our revenue in this concession does not depend on traffic volume.

Additional Toll Road Projects

We continuously
evaluate infrastructure projects and strategically present public-private partnership proposals and participate in bidding processes for road concessions. In 2012 we were awarded, and in 2013 we signed the contract for, a 40-year concession for a 4.6 km extension of Vía Expresa Sur, one of the main roads in Lima, which crosses the city from north to south. The road will connect downtown Lima to Panamericana Sur, a highway that
runs from Ecuador to Chile. Our estimate of the total investment under the concession, as submitted in our bid, is approximately US$200 million (S/.672 million). Such investment will be made during the construction phase, which was originally
to be completed in 2018. Our revenue will derive from the collection of a toll fee upon completion of the construction. The concession is expected to generate a minimum annual revenue of US$18 million (S/.60.5 million) during the first two
years of the concession term, US$19.6 million (S/.65.9 million) for the third year. If in a particular year, our annual revenue is lower than the minimum guaranteed, we expect the government to compensate us for the difference, up to an

amount not to exceed US$10 million (S/.33.6 million). The beginning of the construction phase is subject to expropriation by the government of the land necessary for the construction of the
road. Moreover, in June of 2017, we signed Initial and Additional Acts of Suspension of the Concession with the municipality of Lima to freeze the reponsibilities of the government, on the one hand, and the concessionaire, on the other hand, with
respect to the concession for a period of 12 months. The concessionaire continues to act as custodian of certain assets of which it had taken possession and continues to maintain certain performance guaranties in connection with the concession.
Also, the government and the concessionaire continue to meet and coodinate aspects of the project, with the goal of resuming operations. We cannot assure you that this concession contract will be resumed.

A joint operation in which we have a 50% interest has been awarded, and is in the process of negotiating the terms for, a 37-year concession for Via Expresa Javier Prado, a 20 km toll road that crosses Lima from east to west, traversing through eight districts. According to estimates from the Municipality of Lima, the total investment
in the concession is expected to amount to approximately US$700 million (S/.2,352 million). Such investment will be made during the construction phase which is expected to take between five to seven years. Our revenue will derive from the
collection of a toll fee upon completion of the construction. This concession was awarded to the joint operation at the end of the 1990s and negotiations were discontinued but were resumed in 2012. A project contract was approved by the City of
Limas Council in November 2013 and was submitted to the Peruvian Ministry of Economy and Finance, which requested additional studies prior to approving the project. Subsequently, the municipality of Lima signed an agreement that annulled the
granting of the private initiative. The company has initiated legal action in Peru against such decision. A preliminary injunction is pending that would prevent the municipality of Lima from granting the private initiative to another party. We
cannot assure you that our position in these proceedings will prevail, nor can we assure you if or when the concession contracts will be agreed or whether the contractual terms will be favorable to us. See Item 3.D. Key InformationRisk
FactorsRisks Related to our Infrastructure Business.

Mass Transit

Lima Metro

In 2011, we were
awarded a 30-year concession for the operation of Line One of the Lima Metro, Perus only urban railway system. The concession was awarded to our subsidiary GyM Ferrovías, in which we hold a 75%
ownership interest, with the other 25% being held by Ferrovías S.A.C. Our obligations under the contract include: (i) the operation and maintenance of the five trains provided by the government; (ii) the acquisition of 19 new trains
on behalf of the Peruvian government, which will be the legal owner of such trains; (iii) the operation and maintenance of the 19 new trains (24 trains in the aggregate); and (iv) the design and construction of the railway maintenance and
repair yard, which was built by our E&C segment. We currently have all 24 trains (including two backup trains) in operation. The construction of the second stretch of Line One was completed in July 2014, and started operations on July 25,
2014.

We entered into the fourth addendum to the Lima Metro concession contract on July 11, 2016, in order to expand the
transportation capacity of Line One. In accordance with the fourth addendum, the expansion project involves: (i) the purchase of 20 new trains with five-car from Alstom; (ii) the purchase of 39
new cars from Alstom, to be coupled with the 19 existing Alstom trains and the 20 new Alstom trains, resulting in a consolidated fleet of 39 Alstom trains with a six-car configuration; and (iii) the
expansion and improvement of the existing infrastructure, including revamping and improvement of five stations, improvements in the electrical systems, a new access route to the maintenance workshop and new switches on the main track. The
construction of the expansion of the infrastructure will be carried out by our E&C segment and it is scheduled to be completed by the end of 2018 with the additional trains and rail cars to be delivered by the end of 2019.

As compensation for the investments of the expansion project, we are entitled to receive from the Ministry of Transportation and
Communication, an advance payment of 30% of each investment component as well as the balance of 70% of each investment component compensated through an annual payment for complementary investments (pago annual por inversiones
complementarias), which represents the unconditional and irrevocable right to receive a series of 56 quarterly payments from the Ministry of Transportation and Communication. In 2016 we already received the advance payment of the trains and
cars, and in the third quarter of 2017 we expect to receive the advance payment corresponding to the infrastructure expansion.

The
construction of the first and second stretches of Line One was carried out by our E&C segment. The operation and maintenance of the trains is carried out by our Technical Services segment. The map below shows the route of Line One.

##### Table of Contents

LOGO

As of December 31, 2016, GyM Ferrovías had spent a total of S/.660 million (US$196
million) in capital expenditures in connection with the Lima Metro.

Our revenue from this concession consists of a quarterly fee that we
receive from the Ministry of Transport and Communications based on the kilometers travelled per train and adjusted for inflation, with the fee per kilometer, the number of trains required to be in operation and the number of kilometers that we are
required to travel established by the terms of the concession. Our revenues do not depend on passenger traffic volume.

We currently
operate 24 trains (including two backup trains) on the first and second stretches which enable us to travel 2,603,453 kilometers per year based on required schedule and frequency. The full Line One consists of 33.1 kilometers. The average frequency
of the trains is 6 to 10 minutes and the fee per kilometer travelled is S/.80.37.

Additionally, as of April 30, 2018, we operate
eight new trains from a complementary investment, which we expect to enable us to travel 581,106 kilometers per year. The fee per kilometer travelled is S/.53.50.

Trujillo Urban Transportation

In October 2014, our subsidiary GMD was awarded a concession for the electronic collection of public transportation fares in the city of
Trujillo in northern Peru for a period of 20 years. The concession includes equipping buses with communication systems, GPS, video and fare collection systems; managing a bus fleet control center (for speed, punctuality, and observance of the
routes); installing card sale and charge points; and conducting inspections onboard buses. The estimated initial investment for the first three years is US$22 million (S/.73.9 million). We have committed to renew the equipment upon its wear
down due to common use. Such technological renovation is estimated at US$18 million (S/.60.5 million), which will be paid over the following eight years. The contract was signed in April 2016. On June 6, 2017, we sold our interest in GMD.

Water Treatment

In 2010, we were
awarded a 25-year concession for the construction, operation and maintenance of La Chira waste water treatment plant in the south of Lima. The project is aimed at addressing Limas environmental problems
caused by sewage discharged directly into the sea. We hold a 50% share in this concession and our partner Acciona Agua holds the remaining 50%. The plant began operations in June 2016.

La Chiras total investment in the concession was S/.250 million (US$74.4 million). Once the project is completed, La Chira will be
entitled to collect (i) an annual payment for the investment made in the construction of the project for an amount of S/.24.2 million (approximately US$7.1 million), and (ii) and annual payment for the operation and maintenance of the
project for an amount

of S/.6.8 million. These fees will be paid by Sedapal S.A., the public utility company responsible for the supervision of the water service in Lima, for a period of 25 years. We funded our
construction costs related to La Chira through the sale of government certificates to financial institutions, and, as a result, will not receive future cash flows from item (i). See Item 5.A. Operating and Financial Review and
ProspectsOperating ResultsFactors Affecting Our Results of OperationsInfrastructure. A joint operation in which our E&C segment participates is undertaking the construction of the waste water treatment plant.

Energy

We currently operate three energy
businesses within our Infrastructure segment: Exploration and Production; Natural Gas; and Transport and Distribution. We operate and extract oil from four onshore fields (Block I, Block III, Block IV and Block V) located in the provinces of Talara
and Paita in northern Peru. We have two long-term hydrocarbon extraction service contracts with Perupetro, the Peruvian entity responsible for the administration and supervision of all exploration and production contracts in Peru, under which we
operate two oil producing fields, Blocks I and V. In addition, we have two long-term license contracts with Perupetro for two other blocks, Block III and IV, which started operations in April 2015. During 2016, the oil production of our four blocks
was approximately 2,756 bbl per day. We also own and operate a natural gas processing plant located in northern Peru, which processes and fractions natural gas liquids and delivers dry gas to a gas-fired power
generation company under a long-term processing and fractionation agreement. In addition, we are a 50% partner in two consortiums named Consorcio Terminales (CT) and Terminales del Peru (IP) both of which have contract with Petroperú, a state
owned oil and gas company, to operate and maintain ten fuel storage terminals.

In addition, we are a 50% partner in Oil Tanking Andina
Services S.A.C. (OTAS). This subsidiary operates a fuel terminal named Terminal Marino Pisco Camisea under a contract subscribed with Pluspetrol to operate an export terminal for gasoline, diesel, propane and butane.

Oil and Gas Production

We operate and extract oil from four mature fields (Block I, Block III, Block IV and Block V) located in the provinces of Talara and Paita in
northern Peru. Two of these fields, Blocks I and V, are operated under long-term service contracts under which we provide hydrocarbon extraction services to Perupetro. Hydrocarbons extracted from these two blocks belong to Perupetro, which in
turn pays us, twice a month, a variable fee per barrel of lifted hydrocarbons. This extraction fee is based on a basket of international crude prices and the level of production. The other two fields, Blocks III and IV, are operated under long-term
license contracts with Perupetro. The hydrocarbons extracted are owned by our subsidiary GMP, which in turn pays royalties, on a fortnightly basis, to Perupetro, based on a basket of international crude prices and the level of production. Our
activities are focused on proved reserves development and production and are conducted in mature oil fields, which have been producing oil for over 100 years in the case of Block I, approximately 96 years in the case of Block III, approximately 95
years in the case of Block IV, and over 50 years in the case of Block V. We believe our activities in these fields bear limited exploration risk.

The following table shows selected information about our fields.

Block I:

We operate and extract oil and natural gas from Block I under a 20-year hydrocarbon extraction service
contract with Perupetro, which was extended for an additional 10-year term and expires in December 2021. Average daily production during 2016 was 1,040 barrels of crude oil. We operate 241 wells using various
oil extraction systems and operate a network of production batteries and pipelines to collect, measure and deliver oil in fiscalization point close to the Talara refinery. The field is located in the province of Talara, department of Piura, in
northern Peru, approximately five miles from the Talara refinery, the second largest refinery in the country. Block I is the oldest oil producing field in Peru and has been producing oil since around 1890.

Block III:

We operate and
extract oil and natural gas from Block III under a 30-year license agreement with Perupetro, which expires in April 2045. Average daily production during 2016 was 953 barrels of crude oil. We operate 207 wells
using various oil extraction systems and operate a network of production batteries and pipelines to collect, measure and deliver oil in a fiscalization point close to the Talara refinery. The field is located between the provinces of Talara and
Paita, department of Piura, in northern Peru, approximately 21 miles from the Talara refinery.

Block IV:

We operate and extract oil and natural gas from Block IV under a 30-year license agreement with
Perupetro, which expires in April 2045. Average daily production during 2016 was 640 barrels of crude oil. We operate 250 wells using various oil extraction systems and operate a network of production batteries and pipelines to collect, measure and
deliver oil in a fiscalization point close to the Talara refinery. The field is located in the province of Talara, department of Piura, in northern Peru, approximately 21 miles from the Talara refinery.

Block V:

We operate and extract
oil and natural gas from Block V under a 20-year hydrocarbon extraction service contract with Perupetro, which was extended for an additional 10-year term and expires in
October 2023. Average daily production during 2016 in this field was 128 barrels of crude oil. We operate 59 wells in this field using various oil extraction systems. The Block V field is located in the province of Los Organos, department of Piura,
Peru, close to the border with Ecuador. Block V has been producing oil since the 1950s.

The map below shows the geographic
location of our oil producing blocks in northern Peru.

For Block I and Block V, we are entitled to a variable fee, which is based on the level of production of
each field and a price formula that is based on an average price of three international crude oil prices: fortis blend, suez blend and oman crudes, and a discount over this price of approximately of 17% per barrel.

For Block III and Block IV, the formula price is also based on an average price of three international crude oil prices: fortis blend, suez
blend and oman crudes. The royalties paid to Perupetro were US$16.58 per barrel during 2015 and US$12.76 per barrel during 2016.

During
2014, 2015 and 2016, we received an average revenue (for all blocks) of US$77.33, US$45.59 and US$38.55 per barrel of extracted oil, which was equivalent to approximately 78.1%, 84.26 % and 88.52%, respectively, of average Brent crude oil
prices in the same years. We are not committed to provide a fixed volume of oil or natural gas under our four contracts.

We produce
natural gas as a byproduct of the production of crude oil (an average of 9.4 MMcf per day during 2016). In Block I, we provide natural gas to EEPSA under a take or pay contract (an average of 3 MMcf per day), and we pay to Perupetro a
fee which varies depending on market conditions. The additional volume of natural gas extracted is sent to our Pariñas plant to be processed and commercialized as liquid natural gas. In Block V, we reinject the natural gas produced back into
the wells. In Block III, we use part of the produced gas as fuel to operate wells equipment (pumping units) and we are looking for a market to sell the excess. In Block IV, we also use a volume of gas as fuel and the residual volume is burnt. Our
revenues for the sale of natural gas are not material relative to our oil production revenues.

Proved reserves are those quantities of oil and natural gas which, by analysis of geosciences and engineering
data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations. The term reasonable
certainty implies a high degree of confidence that the quantities of oil and/or natural gas actually recovered will equal or exceed the estimate. To achieve reasonable certainty, we employed methodologies that have been demonstrated to yield
results with consistency and repeatability. The methodologies and economic data used in the estimation of the proved reserves in the fields include, but are not limited to, well logs, geologic maps and available down hole and production data,
seismic data, and well test data.

Reserve amounts were based on the 12-month unweighted
arithmetic average of the first-day-of-the-month Brent crude price for each month in the
period January through December 2016, which, pursuant to our contractual agreements, resulted in average oil and gas prices of US$42.9 per barrel and US$1.324 per Mmbtu, respectively, that for the purpose of reserve amount estimation were assumed to
remain constant.

Proved undeveloped reserves in the fields as of December 31, 2016 were 16,670 MBbbl consisting of 16,670 Mbbl of
crude oil (0 MMcf of proved undeveloped reserves of natural gas). We estimate that during 2016, proved undeveloped reserves increased by 2,729 Mboe of crude oil and approximately 621 Mboe of crude oil of proved undeveloped reserves were converted
into proved developed reserves. Capital expenditures, for both drilling activities and workovers, made during 2016 to convert undeveloped reserves to prove developed reserves amounted to approximately US$5.9 million (S/.19.8 million).

a royalty as per the extracted hydrocarbons.

|(3) | Crude oil sales volume differs from total production volume due to operational circumstances such as the inventory of product stored in our field batteries at the end of each monthly measurement. Average sales
prices refers to the fees received in consideration for our extraction services, which do not equal the sales prices of crude oil. Average sales prices have been calculated using a basket price formula according to the service and license
contracts of each block. Such formulation is at a discount to global oil prices for Blocks I and V, and for Blocks III and IV we pay royalties on the oil extracted. Per unit costs have been calculated using sales volumes.

During 2014, 2015 and 2016
we invested US$25.6 million (S/.76.5 million), US$3.8 million (S/.13.0 million) and US$5.4 million (S/.18.1 million), respectively, in drilling activities. We drilled a total of eleven wells during 2016 in Block IV. All of them are
productive wells.

Under the terms of our agreements with Perupetro, at the time the contract terminates, we are required to close non-producing wells that we have drilled. As of December 31, 2016, we estimated that we will be required to close 48 wells in Block I in December 2021 and 6 wells in Block V in October 2023, 40 wells in Block
III and 50 wells in Block IV in December 2045. We have created a provision in our financial statements for the costs relating to those well closings. See notes 4.1(d) and 17(d) to our audited annual consolidated financial statements included in this
annual report.

Gas Processing Plant

We own a gas processing plant located 7 km north of the city of Talara in Piura, Peru. We currently have under a long-term delivery and gas
processing and fractioning contract with EEPSA, according to which EEPSA delivers wet natural gas that it purchases from onshore and offshore gas operators in the area. We then process and fraction the gas into two products: (i) dry natural
gas, which can be used as fuel in EEPSAs gas-fired turbine; and (ii) natural gas liquids, which are sold in the Peruvian market. Under the terms of the agreement, we are responsible for all
operating costs of the gas processing plant but are also entitled to keep revenues from the sale of the natural gas liquids to third parties after payment of a variable royalty, based on the volume of gas processed, to EEPSA. Our current gas
processing and fractionation contract with EEPSA expires in 2023.

Our gas processing plant has the capacity to process up to 44 MMcf per
day. We processed 27.3 MMcf per day during 2014, 31.7 MMcf per day during 2015 and 33.2 MMcf per day during 2016. Approximately 70% of the volume processed by our gas processing plant depends on the gas volumes provided by EEPSA for processing and
use on its gas-fired turbines. These volumes vary per month and depend upon the power dispatch curve of EEPSA among Peruvian power generation plants. In rainy months (December to April) where hydroelectric
power generation in Peru is typically higher, gas volumes demanded by EEPSA are lower than in dryer months (May to November) in which activity of thermal generators tends to be higher. The remaining approximately 30% of the volume processed by our
gas processing plant depends on the volumes of gas extracted by GMP in Block I, which we process and commercialize as liquid natural gas.

Fuel Storage
Terminals

We are a 50% partner in Consorcio Terminales with a Peruvian affiliate of Oiltanking GmbH, one of the worlds largest
operators of independent terminals for bulk liquid storage. Consorcio Terminales had a contract with Petroperú to operate the North and South Fuel Terminals in Peru, which expired in August 2014. In May 2014, there was a public bidding for
the operation of the North, Center and South Terminals. In June 2014, Terminales del Perú, a new consortium also integrated by our subsidiary GMP S.A. and Oiltanking Peru was awarded a concession for the operation of the North and Central
Fuel Terminals for Petroperú. The contracts have a 20-year term and consist of the operation of four terminals in the north and one terminal in the center of the country, providing storage and
dispatching bulk liquid fuel. The total amount of the committed investment for both projects is approximately US$37.2 million (S/.125 million), while the total amount of the additional investment, which will be reimbursed, is approximately
US$186 million (S/.625 million). There was no winner in the public bidding for the operation of the South Fuel Terminals, and the contract of Consorcio Terminales was extended through contract amendments: first, for an additional year until
August 2015; subsequently, for two more years until August 2017; and most recently, in July 2017 for an additional year until August 2018. The total amount of the additional investment required during this two year period, which will be reimbursed,
is approximately US$10 million (S/.84 million).

Our open-access terminals offer our customers dependable and critical handling and storage
services for refined petroleum liquid products, maintaining high quality, safety and environmental standards. We provide storage, handling and loading and uploading services for a broad range of refined petroleum liquid products, including gasoline,
aircraft fuel, diesel and heavy fuel oil. We deliver the liquids into two types of transportation systems, railroad cars and cistern trucks. Because of the strategic location of our assets, our deep-water access, inland terminals and our aggregate
storage capacity of 2.2 MMbbl in the North and Central Terminals and of 1.4 MMbbl in the South Terminals, we believe that we are well-positioned to cover the needs of our clients, the two principal refineries in Peru. The map below shows the
location of each of our fuel storage terminals in Peru.



LOGO

Under the current contracts, Consorcio Terminales and Terminales del Perú receive revenues paid in
connection with monthly reserved volume in tanks for refined crude products (storage fee) and for volumes loaded and delivered into railroad cars or cistern trucks to each terminal (throughput fee). The storage fee per barrel, is based upon reserved
volumes whether they are received or not. The throughput fee is paid based on effective barrels delivered per month. During 2014, 2015 and 2016 Consorcio Terminales and Terminales del Perú generated revenues of US$44.5 million (S/.133.0
million), US$66.8 million (S/.228.0 million) and US$74.1 million (S/.249.0 million) (we are entitled to 50% of the joint operation revenues), respectively. Under the contracts, Consorcio Terminales and Terminales del Perú are
responsible for paying the fuel terminals operating and maintenance costs and also paying a royalty fee to Petroperú based on effective barrels delivered each month.

At the current stage of the contracts, any capital expenditure we invest in the fuel storage terminals can be recouped from any present and
future royalties we owe to Petroperú.

Other Terminal Operations

We are a 50% partner in Oiltanking Andina Services S.A.C. (OTAS). This subsidiary operates a fuel terminal named Terminal
Marino Pisco Camisea under a contract subscribed with Pluspetrol to operate an export terminal for gasoline, diesel, propane and butane. In 2016, this terminal dispatched 30.0 million barrels of natural gas liquids. Additionally, through
OTAS, we are also a 25% partner in Logística Químicos del Sur S.A. (LQS), that operates the Terminal de Químicos de Matarani, which in 2016 dispatched 56,713 tonnes of sodium hydrosulfide for
international mining companies. During 2014, 2015 and 2016 these activities generated revenues in the aggregate of approximately US$4.1 million (S/.12.3 million), US$4.6 million (S/.15.7 million) and US$6.3 million (S/.21.2 million),
respectively.

Competition

Our ability to grow through successful bids for new infrastructure concessions or other long-term contracts could be affected as a result of
competition. We view our competition as including both Peruvian and international infrastructure concession operators including joint operations with partners with specialized expertise in the relevant sector. Competition varies on a case-by-case basis, depending on the main purpose of the concession.

We undertake a significant amount of the activities in our Real Estate
segment with partners through financing and commercial arrangements we use to purchase land and to develop real estate projects. See Financing. As a result, a significant amount of our net profit in the Real Estate segment is
attributable to the non-controlling interest of our partners. See also Item 5.A. Operating and Financial Review and ProspectsOperating ResultsResults of OperationsGeneralReal
Estate.

Principal Real Estate Activities

Our real estate developments include the following products:



| |  |  | affordable housing;
| | - |  | -------------------



| |  |  | housing; and
| | - |  | ------------



| |  |  | commercial real estate.
| | - |  | -----------------------

We began developing affordable housing projects in 2001, following
the Peruvian governments efforts to address the countrys housing deficit, particularly for low-income families. We launched the first major affordable housing project in Peru in 2007, Parque
Agustino in Limas El Agustino neighborhood. Since 2001, we have completed 16 affordable housing projects. As of December 31, 2016, we are developing eight affordable housing projects, which are in various stages of development, including
six for which the construction phase has been completed, one which is in the construction phase, and one for which we have purchased land, but is still in the process of obtaining the required approvals and permits. Three of our ongoing affordable
housing projects consist of expansions of projects previously completed by us. Affordable housing consists of apartments, usually ranging between 50 and 72 m2, that are purchased through government subsidies. The Peruvian government has adopted the
Nuevo Crédito Mi Vivienda and Techo Propio programs, among others, which promote access to affordable housing in Peru by providing government subsidies to individuals for the purchase of homes. In order for a unit to qualify for the Nuevo
Crédito MiVivienda program, its selling price must range between 14 UIT and 50 UIT (approximately between S/.55,300 and S/.197,500). In order for a unit to qualify for the Techo Propio program, its selling price must range between 5.5 UIT and
20 UIT (approximately between S/.21,725 and S/.79,000).

##### Table of Contents

In order to be eligible for an affordable housing subsidy under the Nuevo Crédito
MiVivienda program, a purchaser must not own any other home or have benefitted from a housing subsidy program in the past, among other requirements. A purchaser must also provide a down payment between 10% and 30% of the total purchase amount.
Housing subsidies under this program fluctuate between S/.12,500 and S/.17,000, which incentivize purchasers with reduced monthly rates so long as they pay their mortgage loan payments on a timely basis. In order to be eligible for an affordable
housing subsidy under the Techo Propio program, a purchaser must have a monthly income that does not exceed 0.48 UIT (approximately S/.1,896) and must not have received any other government-sponsored housing benefit in the past, among other
requirements. A Techo Propio purchaser must also show proven savings equal to at least 10% of the total purchase amount. Housing subsidies under this program fluctuate between four UIT and five UIT (approximately between S/.15,800 and S/.19,750).
Purchasers of subsidized housing under both programs are also not required to pay a value-added tax normally applicable to residential purchases.

We develop substantially all of our affordable housing projects on land purchased from the private sector. To the extent these projects meet
the requirements of a particular government subsidy program, purchasers can purchase units with government subsidies. Some of our affordable housing projects, however, such as Parque Agustino, are developed through government bidding processes.
Government subsidy programs like Nuevo Crédito MiVivienda and Techo Propio have driven the demand for affordable housing in Peru, which has in turn increased our sales of affordable housing units.

Our housing developments consist of residential buildings comprised of apartments with a mid- to
high-price range that do not qualify for government subsidies. Since 1987, we have developed 38 housing developments. As of December 31, 2016, we are developing three housing projects, which are in the construction stage. Our housing units
typically range between 130 and 400 m2 in size.

Substantially all of our affordable housing and housing development
projects are located in Lima. We have also purchased land to develop four affordable housing projects in Piura, Chimbote and Huancayo, two cities north of Lima and one in the center of the country. We intend to develop affordable housing projects in
other cities outside of Lima.

The table below sets forth number of units sold and not yet delivered and number of units
delivered, as well as the value of units sold and our sales revenue for the periods indicated.

We develop and sell office and commercial buildings, such as shopping centers. On certain
occasions, we have operated our commercial real estate and later sold it, such as Larcomar, a landmark shopping center which we built in 1998 and sold in 2010. We have also developed commercial real estate buildings in connection with our affordable
housing and housing projects, such as the Parque Agustino shopping center. Since 1987, we have developed 14 office buildings, three shopping centers and one medical center. We are currently in the process of developing one office building in Lima:
Real II project, which is in the construction phase and is expected to be a 14-floor office building (30% of which is owned by us and 70% of which is owned by Inversiones Centenario S.A.A.).

Land Bank

We typically purchase
land to develop real estate projects with the intention to begin construction within a 12- to 18-month period after the purchase of the land. We may also, from time to
time, purchase land for subsequent resale. As of December 31, 2016, we owned approximately 930 hectares, of which 87% is located in Lima and 13% outside of Lima. We continually evaluate opportunities to purchase new land for our real estate
development projects.

We have a 50.4% interest in Almonte, which owns approximately 812 hectares of undeveloped land in Lurin, located 30
km south of Lima. We previously sold 24 hectares of the land for industrial use, and we expect to sell 71 hectares of the remaining land for industrial use in the next five years. We also expect to develop affordable housing projects on the land
once water and sewage services become available.

On February 24, 2017, we sold our interest in Project Espacio
(formerly known as Cuartel San Martín) to Urbi Propiedades S.A., our partner in the project, for US$50 million (S/.168 million). On April 28, 2017, we also sold our interest (approximately 20.8%) in Promoción Inmobiliaria del
Sur S.A. (PRINSUR) of Inversiones Centenario, which owns approximately 937.66 hectares of undeveloped land also located in Lurin, to its partner Inversiones Centenario S.A.A. for US$25 million (S/.84 million). For more information, see
Item 5.A. Operating and Financial Review and Prospect Operating ResultsRecent Developments.

Financing

We generally fund land purchases for our housing and commercial real estate projects through cash from our operations. For our affordable
housing projects, we generally partner with real estate investment funds and insurance companies that provide between 60% and 70% of the total capital required to purchase the land and cover certain
pre-construction costs in exchange for equity in the project. Once we acquire land for a particular real estate development project, we obtain working capital through a credit line from a financial
institution, which we utilize to finance additional project needs as they arise. We also obtain financing through pre-construction sales for our affordable housing and housing projects and, to a lesser extent,
our commercial real estate projects. Our affordable housing and housing projects generally require less outside financing because they are generally financed with pre-construction sales.

Sales and Marketing

We typically pre-sell our affordable housing and housing units prior to and during construction, and use the related proceeds we receive to finance the construction of the units. Our commercial and sales processes differ
depending on the type of development and market segment of the development. We primarily sell our real estate development projects through an internal sales force that is assigned to particular projects and, to a lesser extent, external brokers on a
non-exclusive, commission-fee basis. Our marketing efforts primarily consist of newspaper advertisements, radio and television commercials, billboards and promotional
offers for referrals. We also advertise our real estate projects on our website.

We believe our brand is associated with product quality,
professional operations and reliable post-sale customer service. We provide customer service call centers through which residents can report complaints or defects. Engineers respond with site visits, and repairs are made as long as the property
continues to be covered by the applicable warranty or guarantee.

For our affordable housing projects, we provide post-sale customer
service through our Ayni program, which aims to preserve the long-term value of our affordable housing developments by promoting a cooperative community life. Through this program, we distribute manuals that teach best practices for living in
communities, offer leadership workshops, budget workshops, promote small business development, facilitate conflict resolution and provide other services. These services are provided for a six- to eight-month
period following project delivery. In 2012, we initiated the Ayni contest for residents of our affordable housing projects with the aim of stimulating the sustainability of their community. Participants present an enhancement project for their
community, such as a recreation center, and a jury selects the best project, which we fund and construct.

Competition

The Peruvian real estate development industry is highly competitive. The market is fragmented and no single company has a significant share of
the national market. The principal competitors for our Real Estate segment are Paz Centenario Global S.A., Paz Centenario Inmobiliaria, Corporación Líder Perú S.A., Urbana Perú, Los Portales, Imagina Grupo Inmobiliario,
ENACORP, Besco S.A. and Gerpal. In the coming years, we expect more competition from domestic and foreign real estate development companies who recognize the growth potential in the Peruvian residential market. The main factors that drive
competition are product design and amenities, price, location and post-sale service offerings.

Technical Services

Our Technical Services segment undertakes a broad range of activities, including (i) the operation and maintenance of infrastructure
assets; (ii) information technology (IT) services for private clients and the government; and (iii) electricity networks services. Characterized by mid-to long-term contracts, our Technical Services
segment further adds a more stable cash flow stream to our consolidated activities.

On June 6, 2017, we sold our 89.19% interest in
our subsidiary GMD to Advent International for US$84.7 million (S/.276.9 million). Beginning on April 1, 2017, we have transferred Concar from our Technical Services segment to our Infrastructure segment. We believe that this strategic
decision will strengthen and boost the operating capacity of our Infrastructure segment by incorporating the experience and knowledge of our Concar team members for concession management.

The table below sets forth selected financial information for our Technical Services business segment.

Operation and Maintenance of Infrastructure Assets

We began providing our operation and maintenance of infrastructure assets services in 1994 when we were awarded the concession for the Arequipa
Matarani highway in southern Peru. With this experience, in 2003, we began providing operation and maintenance services to Norvial. In 2007, the Peruvian government initiated Proyecto Peru, a program aimed at maintaining roads not under concession
to ensure their longevity. Proyecto Peru allowed us to develop new business opportunities providing maintenance services to more than 4,000 km of public roads in Peru. We believe the experience we have gained operating highway and transportation
concessions positioned the company to capitalize on the Peruvian governments initiatives to increase infrastructure development.

Our revenue in the operation and maintenance of infrastructure assets is generated either from fees we charge to Norvial, Survial, Canchaque
and the Lima Metro to operate and maintain our concessions or from government payments through maintenance service contracts we have been awarded. As depicted in the chart below, we operate and maintain more than 3,684 km of Peruvian roads and
highways, including our own highway concessions, in addition to the Lima Metro.

IT Services

We began our IT services business in 1984 providing computer equipment to companies and evolved into a technology solutions provider in 2000.
In the early 1980s, Sonda, one of the main IT services providers in Latin America, was looking for a partner to represent Digital Equipment Corp. (currently, Hewlett Packard Enterprise) for the sale of hardware in Peru. Sondas need coincided
with our diversification strategy and, therefore, we decided to jointly constitute GMD. In 1994, we bought out Sonda. Our main focus was the provision of business process and IT outsourcing services, and providing the necessary corresponding
equipment, to well-known large companies and public institutions in Peru. On June 6, 2017, we sold our interest in GMD.

The
infrastructure through which we operate our business includes the largest software factory in the country, two world class data centers, one of which is Tier III certified and two call centers with high availability for help desk services. In
addition, we have successfully entered into strategic partnerships with key international IT vendors such as Cisco Systems, Microsoft, Hewlett-Packard, Oracle, SAP, IBM, Citrix, VMware, CA Technologies and Louis Berger Group.

On January 4, 2016, we completed the acquisition of a 52% stake in Adexus. Adexus is a leading Chilean company in the development and
implementation of solutions for information technology, with the ability to integrate technological systems of high added value and over 25 years of experience in the market. It has a significant regional presence distributed between Chile, Peru and
Ecuador. The remainder of Adexus is owned by Sistemas y Redes Ltda. with a 47.5% stake and Asesorías e Inversiones Busso with the remaining 0.5%.

The
field services we provide include, among others, installing and maintaining medium- and high-voltage electricity networks and public lighting networks; connecting new residential, commercial and industrial customers to the electrical grid;
disconnecting and reconnecting the power supply of our clients customers; meter reading; verification of electricity theft; and the installation of meters and antitheft solutions. We also provide services that include changing and repairing
damaged electrical equipment and maintaining, transferring and expanding the electrical grid. We have developed a sophisticated management system to monitor the efficiency of the field services we provide and increase the daily productivity of our
field crews.

We also provide specialized services, which involve more technical expertise and specialized equipment, including the
monitoring of electrical consumption for approximately 420,000 industrial, commercial and residential customers. We have developed specialized metering systems and anti-theft solutions for the Latin American markets. We believe we are one of two
companies with a relevant market penetration of these antitheft solutions for power utility companies in our markets. We also operate laboratories that offer an array of services in response to local regulation requirements, such as meter
certification, equipment testing and theft reports.

In Brazil and Chile, we also operate the warehouse facilities of local power utility
companies, which store and distribute the necessary equipment for operations, such as cables, insulators and meters. In addition, in Chile, we lease residential electricity meters to a power utility company, for which we also provide maintenance
services. We have formed strategic alliances with equipment manufacturers in order to develop and commercialize specialized metering systems and anti-theft solutions.

The chart below sets forth the percentage of our 2016 revenues in each of the countries where we operate.

Contracts and Clients

We typically provide our services pursuant to long-term contracts ranging between three and five years. Most of our contracts are awarded
through a non-public bidding process, although some contracts are negotiated directly with the client.

Our principal clients are power utility companies and, to a lesser extent, industrial clients, predominantly in the private sector. In Peru,
we also provide services to the telecommunications industry. Our principal clients are the distribution companies of

##### Table of Contents

Enel, which acquired Enersis. Over the years, we have worked with the principal power utility companies in the region, including Chilectra, Saesa, Chilquinta, AES,
E-CL, Endesa Chile, Ampla, Coelce, Cemig, Coelba, Elektro, Light, Codensa, Emgesa, EEC, Enertolima, Emcalo, Edelnor, Electrocentro, Enosa, and the telecommunication companies VTR, Entel, Claro and
Telefonica.

Competition

The market for electricity networks services is highly fragmented and no single company has a significant share of the national market in the
countries where we operate. We primarily compete with small, local privately-held service companies. We expect competition to increase in the coming years as electricity consumption grows in response to the economic growth, and relatively low per
capita consumption, in the countries where we operate. The main factors that drive competition are safety; product and service quality; reliability; price; and ability to respond to increased industry regulations.

Backlog

We define our backlog as the
U.S. dollar equivalent value of revenue we expect to realize in the future as a result of performing work under multi-period contracts that we have entered into. Backlog is not a measure defined by IFRS, and our methodology for determining backlog
may not be comparable to the methodology used by other companies in determining their backlog. For contracts denominated in soles or other local currencies, amounts have been converted into U.S. dollars based on the exchange rate published by the
SBS on December 31 of the corresponding year.

We do not include backlog in this annual report in our Infrastructure segment for:
(i) our Norvial toll road concession because its revenues from the concession are derived from toll fees charged to vehicles using the highway, and, as a result, such revenues are dependent on vehicular traffic levels; and (ii) our Energy
line of business because: (a) its revenues from hydrocarbon extraction services are dependent on the amounts of oil and gas we produce and market prices, which fluctuate significantly; (b) our revenues from our gas processing plant are
dependent on the amount of gas we process and market prices for natural gas liquids, which fluctuate significantly; and (c) our revenues from our fuel storage terminal operation partially depend on the volume of fuel dispatched; and
(iii) our COGA venture, which is not consolidated because it is jointly controlled (which we sold on April 24, 2017).

When we
present backlog on a segment basis, we do not include eliminations that are included in our consolidated backlog. For a description of how we calculate our backlog, see our segment backlog presented below.

Our consolidated backlog as of December 31, 2016 was US$3,137.4 million. We recognized as revenues 44% of our backlog by
December 31, 2017, and we expect to recognize as revenues 28% of such backlog by December 31, 2018 and 27% of such backlog thereafter. The following table sets forth our consolidated backlog from December 31, 2012 to December 31,
2016.

Our backlog declined in 2016 and may decline further in the future. We cannot assure you that we
will be able to continue obtaining sufficient contracts in the future in number and magnitude to grow our backlog. Additionally, the amount of new contracts signed can fluctuate significantly from period to period due to factors that are beyond our
control.

E & C Backlog

To include an engineering and construction contract in our backlog, we assume that each party will satisfy all of its respective obligations
under the contract. We also make assumptions, in agreement with the client, regarding the total expected contract price in the case of unit price and cost-plus fee contracts and the amount of the contract that will be completed in each year. We
adjust our backlog periodically to account for developments related to each project. For projects related to joint operations or equity investments, we only include our percentage ownership of the joint operations or equity investments
backlog. Our E&C segment backlog does not include intersegment eliminations.

Our E&C backlog as of December 31, 2016 was
US$1,977.9 million. We recognized as revenues 43% of our backlog by December 31, 2017, and we expect to recognize as revenues 30% of our backlog by December 31, 2018 and 27% of our backlog thereafter. The following table sets forth of
our E&C backlog from December 31, 2012 to December 31, 2016.

E&C Backlog (in US$ million)



LOGO

The number and amounts of new contracts signed can fluctuate significantly from period to period. For
example, two large mining services contracts were signed in the fourth quarter of 2012 for an aggregate amount of backlog of US$1.1 billion. During that same quarter we also recorded US$259 million in backlog from our Vial y Vives
acquisition. These contracts and acquisition accounted for a significant portion of the growth between December 31, 2012 and December 31, 2013. In the third quarter of 2015, we acquired a 29% participation in the construction consortium of
the GSP gas pipeline project, and, as a result, we incorporated US$1.0 billion in backlog. Due to the termination of the GSP gas pipeline concession on January 24, 2017, we have removed US$855 million from the backlog, representing
30.2% of our E&C backlog. For more information, see Item 5.A. Operating and Financial Review and ProspectsOperating ResultsRecent Developments.

Infrastructure Backlog

In
reflecting an Infrastructure contract in our backlog, we assume that each party will satisfy all of its respective obligations under the contract. For our Infrastructure backlog, we only include contracted revenues expected to be paid during the
next three years following the backlog calculation date. Infrastructure backlog in this annual report does not include our Norvial toll road concession or our Energy line of business. Our Infrastructure segment backlog does not include intersegment
eliminations. We calculate our Infrastructure backlog as follows:



| |  | for the Lima Metro, our Infrastructure backlog assumes that for 2017 we will operate our 24 trains in the Line One, which in the aggregate will travel 2,603,453 kilometers for that year, per fare per year, and for 2018
and 2019 we will operate 44 trains, which in the aggregate will travel 4,811,780 kilometers per year (when the 20 additional trains are at full operation);
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | for our Survial and Canchaque concessions, we assume our contractually agreed upon annual fee, adjusted for inflation. For our 2017 and 2018 backlog, we utilize the same adjustment amount that was utilized for our 2016
fee, which has already been negotiated; and
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | for La Chira, for 2017 and 2018, backlog is calculated to include the fees we will receive under the concession for our operation and maintenance, with no adjustment for inflation.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our Infrastructure backlog as of December 31, 2016 was US$300.7 million. We recognized as revenues 32% of our backlog by
December 31, 2017, and we expect to recognize as revenues 31% of our backlog by December 31, 2018 and 37% of our backlog thereafter. The following chart sets forth the growth of our Infrastructure backlog from December 31, 2012 to
December 31, 2016.

Warranties

For certain of our contracts, we are required to provide performance bonds to ensure compliance with contractual obligations such as
construction works, operation and maintenance of infrastructure assets, among others. The amount of the performance bond varies on a case-by-case basis, depending on the
value of the project. Performance bonds are usually renewed annually until the contractual obligation which they intend to guarantee is fully satisfied.

As part of our real estate sales contracts, we provide a six-months warranty for latent defects, which
covers hidden flaws not discoverable through inspection. The warranty extends to a five-year term if the defects are caused by: (i) the use of materials below the requisite quality standards; (ii) poor execution; or (iii) faulty land.
We also provide a five-year warranty for structural defects, and assume the terms and conditions of our finishes suppliers warranties.

We provide warranties in connection with our IT services. All government contracts include a latent defects clause, in accordance with Article
51 of the Procurement Act which establishes a minimum warranty of one year, although, for some contracts, we provide warranties for two or three years. For contracts involving the sale of equipment or licensing, we provide the manufacturers
warranty and, if a claim arises, we transfer the claim to the manufacturer unless we provided an extended warranty. For software development contracts, we provide a one to three years good performance warranty.

We have had no material disbursement or expenditure related to our warranties in the recent past.

Regulatory Matters

Set forth below is a description of the regulatory framework applicable to our company. We believe we are in compliance, in all material
respects, with applicable laws and regulations in all of our business segments.

Engineering and Construction

Regulatory Framework Applicable to Contracts with the Public Sector

As of the date of this annual report, Perus State Contracting Law, approved by Law No. 30225 (Ley de Contrataciones del
Estado) and its regulations, approved by Supreme Decree No. 350-2015-EF, which entered into force on January 9, 2016, governs services and construction
agreements entered into with public entities. Article 8 of Supreme Decree No. 350-2015-EF establishes that, at the beginning of the contracting process, the contracting
public entity must prepare a technical file describing the characteristics of the services it intends to purchase and the selection process for its counterparts, among other specifications.

Article 46 of
Perus State Contracting Law establishes that participants of any of the foregoing selection processes must be registered in the Peruvian National Registry of Suppliers (Registro Nacional de Proveedores) and must not be disqualified from
contracting with the state. Article 234 of the Supreme Decree No. 350-2015-EF establishes that this registration is renewable as long as a request is submitted to the
Peruvian National Registry of Suppliers 60 days prior to expiration of the registry.

Bidders may participate in the selection process as
part of a joint operation, in which case all members of the joint operation must be registered in the Peruvian National Registry of Suppliers and will be jointly liable for all consequences arising from the joint operations participation in
the selection process and the execution of the agreement.

GyM and GMI are registered in the Peruvian National Registry of Suppliers as a

Article 15 of the Supreme Decree No. 350-2015-EF establishes that, in the case of goods and works, the terms and conditions of the selection process must indicate the execution type of the agreement as follows:



| |  |  | turn-key (llave en mano), when completion is subject to the construction, equipment and operations, and, if applicable, the submission of the technical file in
connection with the bidding process; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | bid contest (concurso oferta), when completion is subject to the submission of the technical file, the completion of the work or land, as applicable. This completion type is only applicable to lump-sum contracts and public bidding selection process.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Perus State Contracting
Supervising Agency (Organismo Supervisor de las Contrataciones del Estado, or OSCE), a public-sector entity within the Peruvian Ministry of Economy and Finance, supervises and oversees the selection processes carried out by public
entities; manages the Peruvian National Registry of Suppliers; imposes penalties to suppliers that violate the provisions set forth in Perus State Contracting Law, its regulation and other related provisions; and informs the governments
General Comptroller (Contraloría General de la República) regarding violations to the regulations when damages are caused against the state. As of the date of this annual report we do not believe that Perus State
Contracting Law and Supreme Decree No. 350-2015-EF will have a material impact on our business.

Regulatory Framework Applicable to Contracts with the Private Sector

Parties to a private-sector agreement may freely determine the contract type and its contents as long as it complies with certain legal
requirements, including the provisions set forth in Article 1353 of the Peruvian Civil Code (which states that all contracts, including innominate contracts, must comply with the rules of Section VIII of the Peruvian Civil Code, absent a statute
specific to said contract type that collides with said rules). GyM and GMI participate in private-sector contracts for engineering and constructions.

Construction Activities in Peru

Legal Framework

Perus Law for the Promotion of Private Investment in Construction, approved by Legislative Decree No. 727 (Ley de
Promoción de la Inversión Privada en Construcción), states that construction activities in Peru are in the public interest and a national priority. According to Section F of the Fourth review of the United Nations
International Statistical Industrial Classification (ISIC), construction activities typically consist of the construction of dwellings, buildings and stores; and the construction of large scale infrastructure projects such as highways, bridges,
tunnels, railways, irrigation systems, sewage systems, industrial facilities, pipelines and electric lines, among others. GyM has developed numerous projects in the construction sector. Currently, the company focuses on buildings (ISIC Division 41),
civil works (ISIC Division 42) and specialized activities (ISIC Division 43).

Construction entities must comply with the National
Building Regulation, approved by Supreme Decree No. 011-2006-VIVIENDA (Reglamento Nacional de Edificaciones), which establishes that urban allotments and buildings must be developed in compliance with
the rules governing safety, functionality, accessibility, habitability and environmental impact. According to Article 25 of the National Building Regulation, construction companies, such as GyM and GMI, are responsible for (i) executing works
in accordance with project specifications and applicable regulations; (ii) possessing sufficient organization and infrastructure to guarantee the feasibility of the project; (iii) appointing the party responsible for the construction to
assume its technical representation; (iv) providing the resources and materials to complete the project pursuant to the terms of the agreement and required standards and within the approved budget; (v) executing subcontracts within
contractual limitations; and (vi) delivering to the client documented information regarding the executed works.

Notwithstanding any
legal actions that the construction company may take against suppliers, manufacturers or subcontractors, the construction company may be responsible for all the works, including those executed by subcontractors, and for the use of defective
materials or supplies.

Penalties for violating the National Building Regulation are determined by the municipal government in the
jurisdiction where the project is developed, and set forth in its corresponding regulations. In addition, they may also pursue criminal actions or civil claims if applicable.

due to the temporary nature of construction contracts. Consequently, certain general rules such as the trial period are not applicable to construction workers.

The principal terms and conditions relating to collective bargaining from our civil construction workers have been agreed upon and recorded in
the 2015-2016 agreement, dated August 6, 2015, and entered into between the Peruvian Chamber of Construction and the Federation of Civil Construction Workers (Federación de Trabajadores en Construcción Civil). The 2015-2016
agreement included the following benefits: (i) pay increase; (ii) bonuses for employees working 28 consecutive days or more in projects with difficult access; and (iii) paid leave in case of death of a relative of the employee.

The Supreme Decree No. 009-97-SA, Law No. 26790 and
Supreme Decree No. 003-98-SA require construction companies to have complementary high risk insurance for workers that perform high risk tasks. As of the date of this
annual report, GyM has this insurance coverage.

The insurance coverage provides medical care for injured workers to allow them to achieve
full recovery. Moreover, it provides pensions to workers or their beneficiaries in case the worker becomes handicapped or dies as a result of a work accident or occupational disease.

Environmental Regulations

Section 24 of the General Environmental Law, approved by Law No. 28611 (the General Environmental Law), provides that all
human activity likely to cause significant environmental impact is subject of regulation by the National System of Environmental Impact Assessment. The Peruvian Ministry of the Environment, through the Environmental Supervising and Enforcement
Agency (Organismo de Evaluación y Supervisión Ambiental,or OEFA) supervises compliance with the law and enforces environmental rules related to mining, oil and gas and electricity.

In addition to being responsible for the impact that its activities, by action or omission, may have on the environment, GyM is also subject
to an environmental impact assessment and must obtain an environmental certification necessary to obtain project permits or licenses. GyM must also adopt measures for the management of hazardous materials intrinsic to its activities to mitigate the
negative environmental impact its activities may have.

Civil Construction

The Supreme Decree No. 015-2012-VIVIENDA (modified by the Supreme Decree No. 004-2015-VIVIENDA) regulates the environmental aspects of projects related to housing, urbanism, construction and sanitation activities in urban or rural areas. The National Directorate of Housing, Urbanism,
Construction and Sanitation supervises the compliance and enforces the applicable rules. Projects are categorized according to their environmental impact during and after their execution and different rules are established for each category
including compliance with the following environmental studies prior to starting construction works: (i) projects expected to cause minor environmental impacts require an environmental impact statement; (ii) projects expected to cause
moderate environmental impacts require a semi-detailed environmental impact assessment; and (iii) projects expected to cause a major environmental impact require a detailed environmental impact assessment.

Other Subsectors

Depending on the subsector in which it operates, GyM is required to follow specific environmental provisions issued by the competent
authorities. For example, with respect to hydrocarbon activities, the Ministry of Energy and Mines has enacted the Oil and Gas Environmental Regulations, by means of Supreme Decree No.
039-2014-EM.

Tax Legal Regime Applicable to
Construction

Section 63 of the Peruvian Income Tax Law, approved by Supreme Decree No. 179-2004-EF, establishes that construction companies engaged in construction contracts for a period longer than one fiscal year can choose to be taxed under any of the following systems:



| |  |  | allocate to each fiscal year the gross income resulting from applying the percentage of gross margin estimated for the work over the amounts collected for the same work; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | allocate to each fiscal year the gross income calculated by deducting the costs corresponding to the tasks performed during that year from the amount collected or that is expected to be collected corresponding to that
work.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In both situations, a special accounting registry must be kept for each project, which is meant to keep a record of
the costs, expenses and income of each project in an account separate from the general analytical accounts (cuentas analíticas de gestión).

Until December 31, 2012, construction companies could defer revenues related to each individual project until the total completion of the
project, provided the project was completed in three years or less. In such cases, the income was to be recognized in the fiscal year in which the project concluded or was delivered. In case the project was scheduled to conclude in a period
exceeding three years, the results would be determined in the third year in accordance with the progress of the works over the three-year period. Beginning in the fourth year, results were determined following the foregoing methods.

Starting on January 1, 2013, in accordance with Legislative Decree No. 1112, which amended the Peruvian Income Tax Law, construction
companies that adopted the deferral method are authorized to continue with the use of such method only with respect to income arising from the execution of work contracts initiated prior to January 1, 2013, until their completion, and for
execution of work contracts initiated on or after January 1, 2013 the deferral method is no longer accepted.

The Peruvian Income Tax
Law also provides that the difference that may result from a comparison between the real gross income and the income assessed pursuant to any of the methods described above shall be allocated to the fiscal year in which the work concluded.
Additionally, the company must apply the same system to all its construction contracts and must receive prior authorization from tax authorities to change the applied system.

Prevention of Money Laundering and Financing of Terrorism

Regulations for money laundering and terrorism financing prevention, approved by SBS Resolution
No. 486-2008, require construction and real estate companies to implement a money laundering and terrorism financing prevention system, including the appointment of a compliance officer, setting up a
registry of operations and notifying the Financial Intelligence Unit of the SBS, the entity responsible for supervising and enforcing compliance, of any suspicious activity.

Infrastructure

Infrastructure and Public
Services through Public Private Partnership Contracts

As a result of entering into Programa País in December
2014 with the Organization for Economic Co-operation and Development (OECD), the Peruvian state is implementing a new regulatory framework (Legislative Decree No. 1224 and its regulations, approved by
Supreme Decree No. 410-2015-EF) establishing the procedures and ways of promoting private investment for the development of public infrastructure, public services, any
ancillary services, applied research projects and/or technological innovation, through Public-Private Partnerships (PPP) and Projects with State Assets.

The main aspects of the new legal framework are the following:



| | 1. | The Ministry of Economy and Finance (Ministerio de Economía y Finanzas) is the governing authority of the National System for the Promotion of Private Investment (SNPIP), composed by ministries and public
agencies of the national government, The Agency for the Promotion of Private InvestmentProInversión, and regional and local governments.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | Private investment projects will comprise the following stages: (i) planning and programming, (ii) formulation, (iii) structuring, (iv) transaction, and (v) contract execution. Great emphasis is
given to the Evaluation Report (Informe de Evaluación), a document determining the economic, financial and legal viability of a potential Public Private Partnership applying, where appropriate, the national public investment system.
Investors are entitled to receive from the Peruvian state: (a) in the case of self-financed projects, taxes and tolls to be collected from final consumers; (b) in the case of co-financed projects,
subsidies and payments from the public entity awarding the project; and (c) any other financing structure agreed between the parties.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | The management of Public Private Partnership contracts by the three levels of government (central, regional and local) is regulated.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------



| | 4. | For projects in regulated sectors, the monitoring of Public Private Partnership contracts is subject to the provisions of the Law No. 27332, Framework Law on Regulators. According to this law, OSIPTEL, OSITRAN,
SUNASS and OSINERGMIN should primarily safeguard the compliance of service levels agreed in Public Private Partnership contracts. For this purpose, Public Private Partnership contracts must establish the necessary arrangements to ensure timely and
efficient supervision during the contract execution stage. To this end, public entities are required to ensure timely participation of regulatory agencies in the arbitration, when decisions and matters related to the competence of those bodies are
discussed.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 5. | Favorable opinions for the Public Private Partnership contracts from the General Comptroller of Peru are required. The General Comptroller will issue a report on any aspects that may jeopardize the financial capacity of
the Peruvian state, according to Law No. 27785, Organic Law of the National Control System and the General Comptroller of Peru.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6. | Investors interested in participating as bidders in private investment processes must review the list of impediments and prohibitions established in the State Contracting Law. Whether an investor is barred from
participating shall be determined through administrative channels, and such impediment will apply to any expected strategic partners as well. Such partners usually accredit their technical capacity during the promotion process. Furthermore, it is
stated that, in case the contract does not set a strategic partner, the impediment would apply to those who have exercised direct control over the investor, as indicated in the regulations approved by the Superintendence of the Stock Market. If
barred, the ban shall stand for two years; except for the impediments established in the State Contracting Law, which will be valid for the terms indicated in such law.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 7. | The development of projects related to assets owned by the Peruvian state (Legislative Decree No. 674, Law Promoting Private Investment in State Enterprises) can be carried out by private sector initiatives,
without committing any public resources or transferring any risks to public entities, unless expressly required by law.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

Each of our subsidiaries Norvial, Survial, Canchaque and GyM Ferrovías has entered into a
concession agreement with ProInversión and the Peruvian Ministry of Transportation and Communications. La Chira has entered into concession agreements with ProInversión and Sedapal S.A. The abovementioned agreements were entered into
in accordance with the provisions in force at the time of their execution.

Infrastructure Construction and Safety

Infrastructure concessionaires must assure that the construction companies they hire to construct infrastructure projects comply with the
foregoing rules relating to construction projects. In addition, companies engaged in road construction must comply with the guidelines issued by the Road and Railways General Directorate of the Peruvian Ministry of Transportation and Communications
and with the National Road Infrastructure Management Regulation regarding road construction, maintenance and safety. These regulations establish procedures for authorizing road construction and approving work contracts, among others.

Environmental Regulations

Peruvian
environmental laws and regulations have become increasingly stringent over the last decade. All industries and projects are subject to Peruvian laws and regulations concerning water, air and noise pollution, and the discharge of hazardous
substances. The main legislation governing environmental matters is the General Environmental Law; the Law of the National System of the Environmental Impact Evaluation, approved by Law No. 27446 (the SEIA); the regulations of the
SEIA Law, approved by Supreme Decree No. 019-2009-MINAM; and several environmental regulations that have been issued under the General Environmental Law, SEIA and other laws by the government with the
collaboration of the Peruvian Ministry of the Environment.

Since the enactment of the General Environmental Law in October 15, 2005,
several technical environmental regulations have been issued and this environmental regulatory framework is generally revised and updated regularly. Some regulations apply generally to Peruvian industries and some technical regulations are issued
for specific industries.

The main environmental rules applicable to infrastructure projects include those described above in
Engineering and ConstructionEnvironmental Regulation.

Peruvian Hydrocarbon Regulation

Our hydrocarbon operations are subject to governmental regulations as described below.

Exploration and Production

GMP is
engaged in two major activities relating to the exploration and production of oil and gas: exploration and production of oil fields; and providing services to the oil industry.

Exploration and Production of Oil Fields

Perus hydrocarbon legislation regarding oil and gas exploration and production activities includes, among others, the Hydrocarbon Organic
Law and the regulations governing the qualification of petroleum companies; the exploration and production of hydrocarbons; the transportation of hydrocarbons; hydrocarbons pipelines and safety requirements in such activities.

The foregoing regulations define the roles of Peruvian government agencies which regulate the oil and gas industry; provide the framework for
the promotion and development of hydrocarbon activities based on the principles of private-sector competition and access to all economic activities; and set the safety and security standards as well as the legal proceedings for carrying out
operations.

The Peruvian Constitution establishes that the government is the sole proprietor of underground hydrocarbons within its
national territory. However, the Peruvian government has granted Perupetro, a state-owned company authorized to negotiate and enter into agreements for the exploration and/or production of hydrocarbons, the ownership right over the hydrocarbons
extracted which allows Perupetro to enter into such agreements. Furthermore, the Peruvian Ministry of Energy and Mines, the Environmental Evaluation and Supervision Agency (OEFA) and OSINERGMIN constitute public entities that play an
active role in oil and gas regulation.

The Peruvian Ministry of Energy and Mines is responsible for devising energy and mining policies;
supervising activities in the energy and mining sectors; and promoting investments in those sectors. Within the Peruvian Ministry of Energy and Mines, the General Directorate of Hydrocarbons (DGH) is responsible for regulating the
development of oil and gas fields and the General Directorate of Energy-Related Environmental Affairs (DGAAE) is responsible for reviewing and approving regulations related to environmental risks associated with hydrocarbon exploration
and production activities.



93



---

##### Table of Contents

OEFA is a public entity ascribed to the Peruvian Ministry of the Environment and is responsible
for evaluating and ensuring compliance with applicable environmental rules covering hydrocarbon activities, as well as for initiating sanctioning proceedings when a breach of an environmental regulation occurs. OSINERGMIN is a public entity ascribed
to the Presidency of the Council of Ministers (Presidencia del Consejo de Ministros) office and is responsible for ensuring compliance with safety and security standards in the hydrocarbon industry, as well as for sanctioning
proceedings. GMP is subject to the supervision, authority and regulations enacted by the foregoing agencies.

Regarding hydrocarbon
exploration and production activities, companies are required to enter into either a licensing or a services agreement with Perupetro; other contractual arrangements are permitted with prior approval from the Peruvian Ministry of Energy and Mines.
The foregoing agreements are governed by private law and must be approved by the Peruvian Ministry of Energy and Mines and the Peruvian Ministry of Economy and Finance. In licensing agreements, licensees obtain authorizations to explore and produce
hydrocarbons in a determined area, are granted ownership over the extracted hydrocarbons and are subject to the payment of royalties. Licensees may trade the hydrocarbons with no limitations on sales prices, except in the event of a national
emergency.

Services agreements grant contractors the right to perform hydrocarbon exploration and production activities in a determined
area and receive compensation according to the production of hydrocarbons. The contractor is technically and financially responsible for the operations, but Perupetro maintains the ownership over the hydrocarbons extracted. GMP is party to services
agreements with respect to Blocks I and V, and to licensing agreements with respect to Blocks III and IV. Each block has an independent contract with Perupetro.

Services and licensing agreements are intended for the development, production and eventually transportation of hydrocarbons, as well as for
certain storage activities. Services and licensing agreements commonly include a minimum performance schedule guaranteed by performance bonds and require corporate guarantees to be issued to secure the contractors compliance to the provisions
established by the parties.

Additionally, a company must be qualified by Perupetro prior to entering into hydrocarbon exploration and
production agreements. In order to qualify, a company must meet the standards under the Regulations on the Qualification of Petroleum Companies, requiring companies to demonstrate that they have the technical, legal and financial capacity to comply
with all the obligations they will assume under the agreement with Perupetro. Such capacities are measured according to the characteristics of the area to be explored or produced, the expected investment required for the project, and the strict
fulfillment of the rules regarding prior consultation (if applicable), citizen participation and environmental issues related to the operations performance. Upon a positive evaluation, the company is issued a qualification certificate from
Perupetro that allows it to initiate the negotiations of the agreement; notwithstanding the company remains responsible for obtaining all other licenses, permits and approvals required by applicable regulation.

Under the current regulation, 30 years is the maximum term of services and licensing agreements for the production of crude oil. On the other
hand, natural gas and condensates-related services or licensing agreements have a maximum term of 40 years. Graña y Montero acts as GMPs guarantor in all of the Block I, Block III, Block V and Block VI contracts.

GMP must comply with Supreme Decree No. 043-2007-EM for its
activities relating to hydrocarbons in all phases. The OSINERGMIN is the authority responsible for the supervision and enforcement of the foregoing rules.

Services to the Petroleum Industry

Peruvian regulation provides that all companies that enter into a service agreement with any company that holds a licensing or services
agreement must be registered as a subcontractor in the Hydrocarbons Public Registry in case they render any of the following services: (i) geological studies, geophysical studies, petroleum engineering related to drilling operations, production
and well services; or (ii) construction of oil pipelines, gas pipelines, refineries and their maintenance, and specialized transportation by land, air, sea or river. In order to register a company as a subcontractor in the Hydrocarbons Public
Registry, prior authorization from the General Directorate of Hydrocarbons (DGH) of the Peruvian Ministry of Energy and Mines is required.

On June 1, 2004, GMP was included as a subcontractor for the petroleum industry in the Hydrocarbons Registry of Limas Public
Registry of Legal Entities; such registry remains in force as of the date of this annual report.

Environmental Regulations

The Peruvian Ministry of Energy and Mines is responsible for enacting environmental regulation for the oil and gas sector. The Oil and Gas
Environmental Protection Regulation, approved by Supreme Decree No. 039-2014-EM, sets out the legal framework and specific rules applicable to the exploration,
production, refinement, processing, transportation, commercialization, storage and distribution of hydrocarbons, with the aim of preventing, controlling and remedying the negative environmental impacts arising from the foregoing activities.

The Peruvian Ministry of the Environment establishes general rules applicable to different activities in several sectors, in contrast to the
specific rules enacted by the Peruvian Ministry of Energy and Mines regarding the oil and gas sector. Environmental laws and regulations are enforced by the National Environmental Enforcement Agency, OEFA (Organismo de Evaluación y
Fiscalización Ambiental) which was created in 2008. Sanctions range from warnings and fines to suspensions of activities and mitigation of environmental damages, among others. In this regard, a breach of the obligations contemplated in
the Environmental Impact Assessments in the hydrocarbons sector may originate fines up to 30,000 Tax Units (approximately US$42 million or S/.141 million)according to the applicable law.

The main environmental rules applicable to GMPs hydrocarbon projects include:



| |  |  | filing an environmental impact study or adopting the necessary measures to prevent and/or mitigate the environmental impact resulting from their activities;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | meeting minimum size, environmental and safety requirements applicable to worksites; handling and storing of hydrocarbons pursuant to safety and environmental requirements; establishing programs to monitor environmental
issues; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | providing training on environmental matters related to employee and personnel activities and responsibilities, especially with respect to regulations and procedures established for environmental protection and the
environmental and legal consequences of non-compliance.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Operation of Terminals

In accordance with the Glossary, Acronyms and Abbreviations for the Hydrocarbons Subsector approved by Supreme Decree No. 032-2002-EM, a terminal is a facility that includes storage tanks, submarine lines or docks for receiving or dispatching liquid hydrocarbons and facilities related to
activities of storage and reception and/or dispatch of liquid hydrocarbon from/to vessels.

Consorcio Terminales and Terminales del
Perú are two joint operations conducted by GMP and Oiltanking Peru S.A.C. which currently operates ten of Petroperús terminals in Peru: (i) the South Terminals of Pisco, Mollendo, Ilo, Juliaca and Cuzco; and (ii) the
North Terminals of Eten, Salaverry, Chimbote and Supe; including Callao, respectively. Consorcio Terminales and Terminales del Perú provides hydrocarbons handling and storage services in Peru for gasoline, aviation fuel and diesel, among
others.

The operation of both the South and North Terminals was granted through the South Terminal Operation Agreement and
the North Terminal Operation Agreement (the Operation Agreements) dated February 2, 1998, by and among Petroperú and Consorcio Terminales. The Operation Agreements resulted from two tenders in accordance with
Legislative Decree No. 674, and mandate that Consorcio Terminales, as operator of the terminals, be responsible for the storage, handling, additivation and dispatch of hydrocarbons in such facilities.

The initial term of the Operation Agreements was 15 years; however the parties agreed to extend the duration of the agreement to an additional
18 months ending in August 2014. The purpose of this extension was to undertake the additional investments that were necessary to satisfy the national demand increase and to perform operative and safety-related improvements to the facilities. In
July of 2014, the Operation Agreements were extended for an additional four years ending in July of 2018. We expect to extend such agreements, at least for a few months.

In executing its operations, Consorcio Terminales is committed to develop and follow a work program which must include an investment schedule.
The work program performed included the installation of fire protection systems and loading systems, among others and was secured by a performance bond.

GMPs activities as a part of Consorcio Terminales fall under the scope of the Hydrocarbons Storage Safety Regulation, approved by
Supreme Decree No. 052-93-EM. Consorcio Terminales is registered in the Hydrocarbon Registry of OSINERGMIN and is authorized to perform transportation activities such as
loading and unloading hydrocarbons from vessels on the terminals. This regulation establishes the conditions under which GMP can operate and maintain storage facilities for hydrocarbons. For instance, the regulation specifies the technical
requirements for storage systems, which vary depending upon the kinds of hydrocarbons stored. Moreover, pursuant to this regulation, GMP must establish procedures to minimize potential risks that these facilities present for employees, third parties
and properties.

Gas Processing Plants

In accordance with the Glossary, Acronyms and Abbreviations for the Hydrocarbons Subsector, approved by Supreme Decree No. 032-2002-EM, a processing plant is a facility where the natural characteristics of hydrocarbons are changed to break them into the different compounds that comprise
them, as well as the subsequent transformations to convert the hydrocarbons into fuel of specific qualities and suitable for transportation. This includes the facilities where the impurities, hydrogen sulfide, carbon dioxide, water and hazardous
components are removed from natural gas.

Our processing and fractionation activities fall under the scope of regulations governing
hydrocarbons refinement and processing including regulations on the design, construction, operation and maintenance of refineries and hydrocarbons processing plants, the oil refining process, the manufacture of natural asphalts, oil and lubricants,
basic petrochemical activities and the processing of natural gas and condensates. In order to comply with these regulations, GMP must take cautionary measures in order to protect the safety of its employees and its facilities, protect the
environment, preserve energy resources and ensure the quality of the products or services it delivers. For instance, GMPs plant operations must be authorized by the General Direction of Hydrocarbons and comply with fire safety regulations. In
the event of an accident, GMP must notify the Peruvian Ministry of Energy and Mines, the Peruvian Ministry of Labor and the Peruvian Social Security Administration.

Terms of our Concessions

Our concessions
are subject to certain terms and conditions established in each concession agreement. During the term of the concessions, we are responsible for the construction and maintenance of the infrastructure necessary to their operation. The concession
agreements establish minimum capital stock requirements for our concessionaire subsidiaries as follows: US$15 million (S/.50 million), US$8 million (S/.27 million), US$0.8 million (S/.2.7 million), S/.46 million and
S/.100 million for Norvial, Survial, Canchaque, La Chira and the Lima Metro, respectively.

The concession agreements establish
grounds for termination including mutual agreement of the parties thereto, force majeure and breach of certain contractual obligations. Additionally, in the case of La Chira and the Lima Metro, the agreement can be terminated unilaterally by the
grantor, with the payment of compensation. On the expiration date, all of the assets that are essential for the operation of the concession are considered the states property and no compensation is paid to the concessionaire.

In the event that changes in legislation or regulations that are exclusively related to the financial conditions of the earnings and/or costs
associated with the investment, operation or conservation of the infrastructure, affect the economic terms of the contract by 10% or more, the concession agreements set forth economic terms adjustment mechanisms aimed at restoring the economic and
financial equilibrium. See InfrastructurePrincipal Infrastructure Lines of Business.

Real Estate

Since 1987, we have been operating in the Peruvian real estate sector. In 2008, we incorporated Viva GyM to concentrate the groups
activities in this sector including promoting and managing real estate projects including affordable housing and housing and commercial real estate projects.

Zoning Regulations

Article 79 of the
Municipalities Organic Law (Law No. 27972) establishes that municipal governments are the exclusive authority responsible for approving urban and rural development plans, as well as the zoning of urban areas under their jurisdiction. Peruvian
regulation states that urban zoning refers to the division of a municipal jurisdiction in zones for specific usage, such as residential, commercial, industrial or mixed-use.

The main zoning rules applicable to our real estate projects include the following: obtaining a construction license from the corresponding
local municipality before commencing construction, reconstruction, conservation or repair of any property.

Environmental Regulations

The Environmental Protection Regulation for real estate, urbanism, construction and regularization related projects, approved by Supreme Decree
No. 015-2012-VIVIENDA, sets out to prevent, mitigate, control and remedy negative environmental impacts that may arise from real estate developments. Prior to initiating construction works, companies are

|------- | --------------------------------------------

The following discussion should be read
in conjunction with our consolidated financial statements included in this annual report, which have been prepared in accordance with IFRS issued by the IASB. The following discussion contains forward-looking statements that involve risks and
uncertainties. Our actual results may differ materially from those discussed in the forward-looking statements as a result of various factors, including, without limitation, those set forth under Part I. IntroductionForward-Looking
Statements and Item 3.D. Key InformationRisk Factors.

A. Operating Results

Overview

We are the largest engineering
and construction company in Peru as measured by revenues during 2016, and one of the largest publicly traded engineering and construction company in Latin America as measured by market capitalization as of December 31, 2016, with strong
complementary businesses in infrastructure, real estate and technical services. With more than 80 years of operations, we have a long track record of successfully completing the engineering and construction of many of the countrys landmark
private and public sector infrastructure projects. Beginning in the mid-1980s, we decided to leverage our engineering and construction expertise into complementary lines of business. We have also undertaken
the engineering and construction of large and complex projects outside our home market throughout our history. More recently, we decided to expand our activities into other key markets of the Latin American region through the acquisition of
businesses with solid positions in those markets.

Recent Developments

Overview

We have participated in
six consortia with affiliates of Odebrecht related to the construction and operation of infrastructure projects in Peru during the period from 2005 to 2017. On December 21, 2016, Odebrecht entered into a plea agreement with U.S., Brazilian and
other authorities in which they admitted to making illegal bribery payments in connection with projects in various countries, including Peru. These projects include certain consortia in which we participated. As a result of the plea agreement,
Peruvian authorities have initiated congressional inquiries and criminal investigations, including against our company and certain of our former directors and executive officers.

Additionally, on January 24, 2017, the Peruvian government terminated the gas pipeline concession held by GSP, consortium in which we
participated with Odebrecht affiliates, due to failure of GSP to obtain the required project financing by the stipulated deadline. The termination of the GSP gas pipeline concession, despite the government payment contemplated under the concession
contract, has had a material impact on our consolidated financial results and backlog.

In response to these events, we have instituted a
multi-step strategic action plan that we are currently in the process of implementing. This strategic action plan includes: (i) monitoring the process for government payment resulting from the termination of the GSP gas pipeline concession;
(ii) renegotiations with creditors of certain debts that became due upon termination of the GSP gas pipeline concession contract; (iii) board approval of the sale of certain non-strategic assets to
repay debt related to GSP; (iv) an internal investigation relating to our participation in consortia with Odebrecht; (v) an assessment to strengthen our anti-corruption compliance program; and (vi) changes to our board of directors
and senior management.

See Item 3.D. Key InformationRisk Factors Risks Related to Recent Developments.

Our Association with Odebrecht

We
have participated in six construction and operation of infrastructure projects in Peru with affiliates of Odebrecht during the period from 2005 to 2017 (known as: IIRSA South Tranche II; IIRSA South Tranche III; IIRSA North; Electric Train Platform;
Gasoducto Sur Peruano; and Chavimochic). Our stakes in these projects ranged from 17% to 33%. During 2016 we only participated

##### Table of Contents

in two of these projects (Gasoducto Sur Peruano and Chavimochic), neither of which are currently ongoing. During the period from January 1, 2005 to December 31, 2016 83% of the projects
carried out by our company, in terms of consolidated revenues, involved the private sector, while projects with Odebrecht accounted for less than 5% of our consolidated revenues during this period. In its plea agreement, Odebrecht admitted to paying
bribes in connection with the IRSA South Tranche II, the IRSA South Tranche III and the Electric Train Platform.

The Chavimochic
concession, awarded in 2013 for the design, construction, operation and maintenance of major hydraulic works in northern Peru, is the only project in which we are currently associated with Odebrecht. Affiliates of Odebrecht own 73.5% of the
Chavimochic-related concessionaire company and construction consortium, and we hold the remaining 26.5% stake. As a result of the governments failure to deliver land required for the project, the projects first phase, hydraulic works,
cannot be concluded, and the projects second phase cannot begin. Since February 2017, the Chavimochic consortium has requested the termination of the concession in light of the governments breach, and the parties are currently in
discussions, including for a potential sale of the project. As of December 31, 2017, our investment in this project amounted to US$8.6 million (S/.29 million) and our portion of the performance guarantee amounted to US$9.5 million
(S/.31.9 million).

Termination of the Gasoducto Sur Peruano Concession

In September 2015, we entered into a memorandum of understanding to invest US$215 million (S/.722 million) for a 20% stake in GSP, a
company that had previously been awarded the concession for the design, construction and operation of the southern gas pipeline, a project to deliver natural gas to the southern region of Peru, particularly to the provinces of Cuzco, Arequipa, Puno
and Moquegua. With our 20% investment commitment, an affiliate of Odebrecht owned a 55% interest and an affiliate of Enagás International, S.L. (Enagas) owned a 25% interest in GSP. As of the date of this annual report, we have
made total investments in the project in an amount of US$243 million (S/.811 million).

On January 24, 2017, the Peruvian
government terminated the concession due to GSPs failure to obtain the required project financing by the stipulated deadline. As a result, we recognized impairment with respect to our investment in GSP and our participation in the related
construction consortium (Consorcio Constructor Ductos del Sur).

In accordance with the concession contract, the Peruvian government is
required to carry out an auction process to sell GSPs assets and obtain a new concessionaire within one year of the contract termination, with the funds raised in the sale to be used to pay the existing concessionaire for its investment in the
project. The amount of the termination payment is required to be no more than 100% and no less than 72.25% of the net carrying amount (valor contable neto), as defined in the concession contract. Consequently, the auction process should
initiate with a base price equivalent to 100% of the net carrying amount. If the auction is unsuccessful in the first round, the government is required to undertake a second round, with a base price equal to 85% of the net carrying amount; and, if
the second round is unsuccessful, the government is required to undertake a third round, with a base price equal to 72.25% of the net carrying amount. If a successful bidder is not obtained within one year of the termination of the contract, the
termination payment to the existing concessionaire would be 72.25% of the net carrying amount.

The Peruvian Ministry of Energy and Mines
announced on April 18, 2017 that the auction process for the new concessionaire of the project assets will be carried out during the first quarter of 2018, notwithstanding the requirements under the concession contract. On April 28, 2017,
a third party was appointed, through an adjudication process, as temporary custodian and administrator of the gas pipeline assets until the new bidder is awarded the concession. Although the concession contract provides that payment must be made
within one year of termination, the Peruvian Ministry of Energy and Mines has not made payment or, to our knowledge, initiated the auction or payment process. Because this payment had not been made, GSPs right to compensation pursuant to the
concession contract should be 100% of the net carrying amount.

In 2016, in connection with efforts to restructure or sell
Odebrechts participation in GSP, due to the corruption scandal surrounding Odebrecht, Odebrecht contractually agreed to subordinate its claims under the concession to the other project partners, Enagás and ourselves. As a result, we and
Enagas may be entitled to repayment of our percentage payment under the concession contract prior to Odebrecht. However, on January 3, 2018, Odebrecht commenced arbitration proceedings against us, our subsidiary GyM and Enagás, seeking
to invalidate the contractual subordination and certain voting and other arrangements.

As of the date of this annual report, we have made
investments in the GSP project of US$243 million (S/.811 million), which we financed in part with borrowings. We have also assumed our proportional obligation to repay the projects bridge loan in an amount of US$129 million (S/.433
million) and the projects performance guarantee in amount of US$52.5 million (S/.176 million) and recorded them as other financial liabilities and other accounts payable, respectively, in our consolidated financial statements as of
December 31, 2016. We also recorded an account receivable for the same amounts, since we have the right to collect these amounts from GSP. According to our estimates, under the terms of the concession contract, taking into account the
subordination arrangement, and based on receiving payment equal to 72.25% of the net carrying amount, in accordance with IFRS, we recorded a provision related to the equity investment in GSP project in the amount of S/.593.1 million
(approximately US$176.5 million) to reflect a write-

off of equity value in GSP. Although GSPs right to compensation pursuant to the concession contract, due to the Peruvian governments failure to pay, is 100% of the net carrying
amount, the company has accounted for 72.25% due to political uncertainty, the bankruptcy process at INDECOPI, and disagreements with the other GSP shareholders. In addition, the gross profit decreased by S/.15.2 million (US$4.5 million) due to
the impact of the early termination of the construction consortium (Consorcio Ductos del Sur), in accordance with IFRS. Also, we registered a discount of the related long term account receivable in financial expenses of S/.76.9 million (US$22.9
million). Adding these three effects, plus the deferred tax effect, we had a net impact of S/.498.0 (US$148.2 million) on our income statement for the year ended December 31, 2016.

The following table shows the effects of the termination of the GSP gas pipeline concession on our results of operations for the year ended
December 31, 2016.

In addition, the termination of the GSP gas pipeline concession has reduced our backlog as of
December 31, 2016, by US$855 million, representing 30.2% of our E&C backlog and 21.4% of our total backlog.

The effects of
the termination of the GSP gas pipeline concession recorded in our consolidated financial statements as of and for the year ended December 31, 2016 are based on our estimates, based on the terms of the concession contract, taking into account
the subordination arrangement, receiving payment equal to 72.25% of the net carrying amount and with the information that we have available to date. The actual impact on our results, however, could change materially from our estimates. Moreover, we
cannot assure you that we will receive the government payment provided for under the GSP gas pipeline concession contract on a timely basis or at all.

Investigations

The Lava
Jato commission of the Peruvian congress, which was formed in November 2016 to investigate alleged bribes made by Brazilian companies to Peruvian public officials, has initiated congressional inquiries into the company and other construction
companies in Peru. These investigations have required certain of the companys former board members and executive officers to provide testimony at hearings before the commission.

In July 2017, media reports alleged that certain construction companies in Peru, Brazil and Spain, including our company, colluded as a
construction club to receive public contracts. As a result of these reports, INDECOPI has initiated an investigation regarding the anti-competitive activities of construction companies in Peru, including our company. In July 2017, the
Peruvian government conducted a search of our facilities related to these allegations. We have provided the information requested by INDECOPI.

In December 2017, Peruvian prosecutors included José Graña Miró Quesada, the
former Chairman of the company, in an investigation for the crime of collusion, and Hernando Graña Acuña, a former board member of the company, for the crime of money laundering against the Peruvian government, each in connection with
the IIRSA South project concession (tranches II and III), in which we participated. Both were placed in preventive detention and have since been released. Gonzalo Ferraro Rey, the former Chief Infrastructure Officer of the company, has also been
included in an investigation for the crime of money laundering in connection with the same project.

In December 2017, we received a
notification from Peruvian criminal prosecutors seeking to include the company as a criminal defendant in the investigation relating to the IIRSA South project concession (tranches II and III). On March 5, 2018, the Peruvian First National
Preparatory Investigation Court (Primer Juzgado de Investigación Preparatoria Nacional) notified us of its decision to formally include the company and GyM in its criminal investigation. We have appealed the courts decision to
include the company and GyM in the criminal investigation. Separately, the Ad Hoc Prosecutor has also moved to directly include the company as a civilly-responsible third party in connection with the project. A decision from the Peruvian judiciary
on whether our company constitutes a civilly-responsible third party remains pending. We cannot assure you that our position in these proceedings will prevail.

On January 12, 2018 criminal prosecutors conducted a search of our facilities regarding the construction club investigation.
We have provided the information requested by the Ad Hoc Prosecutor and the Peruvian criminal prosecutors. A former employee of GyM has been included in the investigation for collusion. To date, there is no formal investigation of the company. We
have provided the information requested by the Ad Hoc Prosecutor.

On February 19, 2018, we also received notice from the Ad Hoc
Prosecutor seeking to directly include our subsidiary, GyM S.A., as a civilly-responsible third party in the investigation relating to Tranches 1 and 2 of Line 1 of the Lima Metro. If our subsidiarys officer or former or current officers are
included and convicted, it may be required to pay civil damages to the Peruvian government. A decision from the Peruvian judiciary regarding these matters remains pending, and we cannot assure you that our subsidiary will not be included or that our
position would ultimately prevail.

We cannot assure you that other of our former or current board members and executive officers will not
be included in the foregoing proceedings as civilly-responsible third parties or criminal defendants as well.

A conviction of corruption
or resolutions with government authorities may lead to criminal and civil fines as well as penalties, sanctions, injunctions against future conduct, profit disgorgement, disqualifications from directly and indirectly engaging in certain types of
business, the loss of business licenses or permits or other restrictions. Moreover, our involvement in corruption investigations, and any findings of wrongdoing in such investigations, could further damage our reputation and have a material adverse
impact on our ability to compete for business. Such investigations may also adversely affect our ability to pursue strategic projects, and could potentially result in the termination or modification of certain existing contracts or relationships.

Emergency Decree and Subsequent Legislation

On February 13, 2017, the President of Peru issued an emergency decree (decreto de urgencia N°
003-2017), prohibiting groups that have been, or whose officers or representatives have been convicted of, or have admitted to, corruption, money-laundering or similar crimes (whether in Peru or elsewhere)
from, among other things, transferring or selling any assets related to investments in Peru, including the proceeds of asset or equity sales, or sending money abroad without a governmental authorization. Section II of Law 30737, promulgated in March
2018 to replace the aforementioned emergency decree, includes companies that have been consortium partners of groups that have been, or whose officers or representatives have been, convicted of, or have admitted to, corruption, money-laundering or
similar crimes. Our company and our subsidiary GyM are two such companies. The law requires that they: suspend money transfers abroad; implement a compliance program and disclose information to competent authorities; and create a trust of assets to
guarantee eventual compensation in favor of the Peruvian government. A Peruvian prosecutor will determine the amount of such guarantee, pursuant to Law 30733. On May 9, 2018, Supreme Decree No. 096-2018-EF was passed, which provides guidelines for such determination. We estimate that we will be required to include in the trust assets worth approximately US$41 million and that our potential
liability should not exceed approximately US$51 million, based on the guidelines. We cannot assure you of the amount of this potential liability, nor can we assure you that the company will have sufficient assets to include in the trust.
Furthermore, we cannot assure you that these laws will not be expanded, or that subsequent laws will not be passed, that impose further obligations or restrictions on our company and our subsidiaries.

Strategic Action Plan

In response
to the recent events described above, we have instituted a multi-step strategic action plan that we are currently in the process of implementing.

Negotiation with Creditors

We have renegotiated three debt instruments related to GSP as follows:



| |  |  | Syndicated Loan Related to our Equity Investment in GSP: As a result of the termination of the GSP gas pipeline concession, our syndicated loan used to finance our equity investment in GSP became due. The
principal amount outstanding under our syndicated loan was US$150 million (S/.504 million) as of December 31, 2016, and is US$76.3 million (S/.256.45 million) as of the date of this annual report. On June 27, 2017, we entered
into an amendment to the credit agreement. According to the terms of the amendment our syndicated loan matures on 2020, with required prepayments to be made with the proceeds of asset sales of 40% in the first year and an additional 30% in the
second year of the amendment. The syndicated loan continues to accrue interest at LIBOR plus 4.90% per year. In addition, we are prohibited from paying dividends until the loan is repaid in full. Also, we have provided additional security interests,
including: (i) a first lien on our shares of GyM and Concar; (ii) a second priority lien on our shares of Almonte; (iii) a first lien on certain real estate properties in Surquillo; (iv) liens on certain related amounts;

| |  |  | Proportional guarantee of the GSP Bridge Loan: As a result of the termination of the GSP gas pipeline concession, our proportional guarantee of the GSP bridge loan became due. As of December 31, 2016, there
was US$129 million (S/.433.3 million) of principal amount outstanding under our corporate guarantee. As of the date of this annual report the principal amount outstanding under the GSP bridge loan has been entirely paid. On June 27, 2017
we entered in a new, US$78.7 million (S/.264.8 million) term loan with Natixis, BBVA, SMBC and MUFJ, the proceeds of which were used to repay the GSP bridge loan. The new term loan matures on 2020, with required prepayments to be made with the
proceeds of asset sales of 40% in the first year and an additional 30% in the second year of the closing date. The term loan accrues interest at LIBOR plus 4.50% per year, which will increase to 5.00% during the second year and to 5.50% during the
third year. In addition, we will be prohibited from paying dividends until our guarantee is repaid in full. Also, we have provided the following security interests to secure repayment of the term loan: (i) a first lien on our rights to receive
the termination payment derived from the GSP termination, (ii) a second priority lien on our shares of GyM and Concar; (iii) a second priority lien on our shares of Almonte; (iv) a second priority lien on certain real estate
properties in Surquillo; (v) a second priority lien on our shares of CAM and CAM Servicios del Perú S.A.; and (vi) a first lien on cash flows from the sale of certain assets. As of the date of this annual report, there is
US$72.4 million outstanding on the term loan; and

| |  |  | Proportional Repayment Obligations under the GSP Performance Guarantee:As a result of the termination of the GSP gas pipeline concession, the government exercised the GSP performance guarantee. As of
December 31, 2016, we had US$52.5 million (S/.176.4 million) in obligations outstanding and, as of the date of this annual report, we have US$15.6 million (S/.52.55 million) in obligations outstanding. On March 31, 2017, we
renegotiated the terms of our repayment obligations owed to Chubb Insurance Company regarding our proportional share of the performance guarantee issued in connection with the GSP gas pipeline concession. The new terms required repayment by
March 31, 2018, extended until June 30, 2018, with interest accruing at 6% per year, and provide a security interest over our shares in CAM and over the cash flows from the sale of certain assets.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In addition, in July 2017, we entered into a financial stability framework agreement with certain banks providing for new lines of credit to support our financial stability and liquidity. In April of 2018, we repaid
US$79.3 million of the facility with the proceeds of the sale of Stracon and as of the date of this annual report we had US$76.9 million outstanding. For more information, see Liquidity and Capital ResourcesIndebtedness.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We are currently in default of certain of the covenants under these financial instruments. For more information, see
Item 13. Defaults, Dividend Arrearages and Delinquencies.

Asset Sales

In order to strengthen our liquidity and financial flexibility, particularly in the event of potential delays in receiving the government
payment contemplated under the GSP gas pipeline concession contract, and make payments on our debt related to the GSP project, our board has approved the sale of non-strategic assets in the amount of up to
US$350 million (S/.1,176 million) in proceeds.

Internal Investigation

In light of the recent events described above, we conducted an internal investigation led by external counsel with respect to our participation
in consortia with Odebrecht. The new Risk, Compliance and Sustainability Committee of our board of directors was charged with monitoring the progress of the internal investigation. The internal investigation identified no evidence to conclude that
any company personnel engaged in bribery in connection with any of the companys public projects in Peru with Odebrecht or its subsidiaries, or that any company personnel was aware of or knowingly participated in any corrupt payments made in
relation to such projects.

Securities Class Action

Two securities class action complaints have been filed against us and certain of our current and former executive officers in the Eastern
District of New York during the first quarter of 2017. These complaints are consolidated into a single class action. We believe that we have meritorious defenses to the claims asserted, and we intend to defend ourselves vigorously in these matters.

Restatement of Financial Results for Fiscal Year 2015

As more fully described in Item 16.F. Change in Registrants Certifying Accountant, we appointed Moore Stephens to re-audit our financial results for fiscal year 2015. The previously issued consolidated financial statements of the company for the 2015 fiscal year (and the related audit opinion) included in the companys
annual report on Form 20-F for the year ended December 31, 2015 should not be relied upon. The restatement of the 2015 fiscal year has resulted in certain significant changes to the companys
consolidated financial statements. For more information on the effects of the restatement, see note 2.30 to the companys consolidated financial statements included in this annual report.

Factors Affecting Our Results of Operations

General

Peruvian, Chilean and Colombian
Economic Conditions

80.1%, 72.9%, and 72.6% of our revenues in 2014, 2015 and 2016 were derived from activities in Peru. Accordingly,
our results of operations are substantially affected by economic conditions in the country and our growth is driven in significant part by growth in the Peruvian economy. In addition 14.4%, 12.1%, and 12.13% of our revenues in 2014, 2015 and 2016
were derived from activities in Chile. We commenced operations in Colombia in December 2014, and 9.3% and 9.4% of our revenues in 2015 and 2016, respectively, were derived from activities in Colombia.

The Peruvian real GDP has grown at an average rate of 3.2% during the three years from 2014 to 2016. With increasing disposable income and an
expanding middle class, private consumption grew at an average annual rate of 4.8% in real terms from 2014 to 2016. In 2014, 2015 and 2016 private investment decreased at an average rate of 2.1%, 4.1% and 6.1%, respectively, in real terms, primarily
due to lower investment in mining. Inflation in Peru, as measured by the change in the consumer price index, was 3.2% in 2014, 4.4% in 2015 and 3.2% in 2016. The sol depreciated versus the U.S. dollar by 6.9% in 2014 and 14.2% in 2015, and
appreciated by 1.6% in 2016. Perus sovereign debt has been rated investment grade by S&P, Fitch and Moodys. At the end of 2016, Peruvian sovereign debt had one of the highest credit ratings in the South American region, rated BBB+ by
S&P (August 2013) and Fitch (October 2013), and A3 by Moodys (July 2014).

The Chilean economy grew at an average annual rate of
1.9% during the three years from 2014 to 2016 in real terms. Total fixed investment declined at an annual average rate of 2.1% in real terms during the three years from 2014 to 2016. Inflation in Chile, as measured by the change in the consumer
price index, was 4.6% in 2014, 4.4% in 2015 and 2.7% in 2016. The Chilean peso depreciated versus the U.S. dollar by 16.0% in 2014 and 16.5% in 2015, and appreciated by 5.7% in 2016. Chilean sovereign debt has the highest rating in the South America
region, rated AA- by S&P (January 2017), Aa3 by Moodys (July 2016) and A+ by Fitch (December 2016).

The Colombian real GDP grew at an average annual rate of 3.2% during the three years from 2014 to 2016. Inflation has increased during recent
years, with inflation of 3.7% in 2014, 6.8% in 2015 and 5.8% in 2016. The Colombian peso depreciated against the U.S. dollar by 24.2% in 2014, 31.6% in 2015, and appreciated by 4.7% in 2016. Colombias sovereign debt was rated BBB by Fitch in
March 2017 and S&P in February 2016, and Baa2 by Moodys in July 2014.

From 2012 to 2016 our revenues grew at a compound annual
growth rate (CAGR) of 3.7% ((0.3)% excluding acquisitions). Our organic revenues decreased 22.7% in 2016 from 2015, principally as a result of lower activity levels in our E&C segment in 2016.

Fluctuations in Exchanges Rates

We
estimate that in 2016, 46%, 33% and 21% of our revenues were denominated in soles, U.S. dollars and other currencies respectively, while 55%, 22% and 23% of our cost of sales during the year were denominated in soles, U.S. dollars and other
currencies. In addition, as of December 31, 2016, 46.7%, 45.6% and 7.6% of our total debt was denominated in soles, U.S. dollars and other currencies, respectively. Accordingly, fluctuations in the value of these currencies can materially
affect our results of operations. When the sol appreciates against the U.S. dollar, our operating margins tend to decrease; when the sol depreciates against the U.S. dollar, our operating margins tend to increase (if everything else were held
equal). Conversely, the appreciation of the sol against the U.S. dollar tends to decrease our indebtedness and financial expenses as expressed in soles; and the depreciation of the sol against the



107



---

##### Table of Contents

U.S. dollar tends to increase our indebtedness and financial expenses as expressed in soles. We enter into derivatives, from time to time, to hedge part of our financial exposure to currency
fluctuations. The value of the sol to the U.S. dollar depreciated in 2014 and 2015, and appreciated slightly in 2016, which impacted our results of operations. See Item 3.A. Key InformationSelected Financial DataExchange
Rates.

We have included estimates of the approximate effects of fluctuations in exchange rates on
our consolidated and segment revenues and costs of sales in Results of Operations. These estimates were calculated based on daily average exchange rates and estimated aggregate revenues and cost of sales denominated in U.S.
dollars, Chilean pesos and Colombian pesos, and were not calculated on a transaction by transaction basis. For additional information on the effect of exchange rate fluctuations on our results of operations, see Item 11. Quantitative and
Qualitative Disclosures about Market RiskExchange Rate Risk.

Cost of Labor, Third-Party Services and Inputs

The largest components of our costs are: labor, which in 2016 represented 26.3% of our cost of sales and 61.0% of our administrative expenses;
services provided by third parties, which in 2016 represented 40.6% of our cost of sales and 27.9% of our administrative expenses; and inputs (including raw materials), which in 2016 represented 16.1% of our cost of sales. For a breakdown of our
cost of sales and administrative expenses, see note 27 to our audited annual consolidated financial statements included in this annual report.

Our cost of labor is influenced by, among other factors, the number of our employees, as well as inflation, competition we face for personnel
in each of our business segments and the availability of qualified candidates. From 2014 to 2015 our personnel charges increased by 14.2% and from 2015 to 2016 our personnel charges decreased by 27.4%. Services provided by third parties include:
subcontracting in our E&C segment, such as carpentry work; advisory and consultancy work, including external audit and legal services; and renting of equipment. From 2014 to 2015 our costs related to services provided by third parties increased
by 38.9% and from 2015 to 2016 our costs related to services provided by third parties decreased by 18.5%. The principal inputs we use are fuel, cement and steel, which in the aggregate represented 18% of our total input costs in 2016. Our costs for
these inputs are affected by, among other factors, the growth or decline of our operations, market prices, including global prices in the case of fuel, and transportation costs. We do not have long-term contracts for the supply of our key inputs.
From 2014 to 2015, our input costs decreased by 4.7% and from 2015 to 2016, our input costs decreased by 13.9%. Our cost of labor, third-party services and inputs decreased in 2016 primarily due to lower activity levels in our E&C segment.

Acquisitions and Dispositions

In
November 2014, we acquired an additional 13.5% interest of Stracon GyM for S/.74.7 million (US$25 million), increasing our stake in Stracon GyM to 87.6%. In December 2014, we acquired a 70% interest in Morelco for S/.277.1 million (US$93.7
million). This transaction represents our first acquisition in Colombia, which is a key part of our international strategy. The results of Morelco are included in our results of operations beginning in January 2015.

In December 2014, we also acquired 51% of the share capital of Tecgas, which holds 100% the share capital of COGA for a total of
S/.75.8 million (US$25.4 million). This investment included goodwill resulting from the purchase amounting to S/.61.4 million. COGA is a jointly controlled entity and accordingly we reflected its results in Share of the profit or
loss in associates and joint ventures under the equity method of accounting. On April 24, 2017, we sold our 51% interest in COGA to our partners Enagas and Carmen Corporation for a price of US$21.5 million (S/.69.8 million). For more
information, see Item 5.A. Operating and Financial Review and ProspectsOperating ResultsRecent Developments.

In
August 2015, we acquired 44% of Adexus S.A., an information technology firm in Chile, for an approximate value of US$13.8 million (S/.44.1 million) through a participation in a capital increase. In January 2016 we acquired an additional 8%
stake in Adexus for an approximate value of US$2.5 million (S/.8.3 million), and in August 2016 we increased our stake in Adexus to 91% for an approximate value of US$4.2 million (S/.14 million).

In September 2015, we acquired a 20% participation in the shareholder ́s equity of Gasoducto Sur Peruano, the concessionaire of the
southern gas pipeline project for a total of US$215 million (S/.722 million). In addition, our subsidiary GyM S.A. participates with a 29% stake in the construction consortium for this project (Consorcio Ductos del Sur), which represented
approximately US$1.0 billion of our backlog as of December 31, 2015. The GSP gas pipeline concession was terminated on January 24, 2017, and as a result, we recognized impairment with respect to our investment in GSP and our
participation in the related construction consortium (Consorcio Constructor Ductos del Sur). For more information, see Item 5.A. Operating and Financial Review and ProspectsOperating ResultsRecent Developments.

As of the date of this annual report, in order to strengthen our liquidity and financial
flexibility, particularly in the event of potential delays in receiving the government payment contemplated under the GSP gas pipeline concession contract, and make payments on our debt related to the GSP project, our board has approved the sale of non-strategic assets in the amount of up to US$350 million (S/.1,176 million) in proceeds. For a detailed description of the sale of these non-strategic assets, see
Item 5.A. Operating and Financial Review and ProspectsOperating ResultsRecent Developments.

Cyclicality

Our Engineering and Construction segment is cyclical as a result of being closely linked to the conditions, performance and growth of the end-markets we serve, which include, among others, the mining, power, oil and gas, transportation, real estate and other infrastructure sectors in Peru, as well as the mining sector in Chile and, the energy sector
in Colombia. These industries tend to be cyclical in nature and tend to be affected by factors such as macroeconomic conditions, climate conditions, the level of private and public investment, the availability of credit, changes in laws and
regulations and political and social stability. As a result, although downturns impact our entire company, our Engineering and Construction segment has historically been subject to periods of very high and low demand. For example, between 2000 and
2003, there was a significant decline in activity in the Peruvian real estate and construction sectors, which consequently affected our and our competitors business and financial performance during that time. The mining and oil and gas
sectors, in particular, are also driven by worldwide demand for the underlying commodities, including, among others, silver, gold, copper, oil and gas, which can be affected by such other factors as global economic conditions and geopolitical
affairs. Furthermore, prevailing prices and expectations about future prices for minerals or oil and gas, costs of exploration, production and delivery of product and similar factors can have a significant impact on our clients exploration and
production activities and, as a result, on their demand for our engineering and construction services.

Our Real Estate segment is also
cyclical and is significantly affected by changes in general and local economic conditions, such as employment levels and job growth, availability of financing for home buyers, interest rates, foreclosure rates, inflation, consumer confidence and
housing demand. In addition, in our Infrastructure segment, our Energy line of business is cyclical and affected by global supply and demand for oil.

Seasonality

Our business, on a
consolidated basis, has not historically experienced seasonality. In our Infrastructure segment, we have experienced moderate seasonality at (i) Norvial, due to heightened vehicular traffic activity during the summer season in the first quarter
of the year, and (ii) GMPs gas processing plant, which typically closes for maintenance during the rainy season in the first quarter of the year, as demand for gas is lower during this time.

Internal Control over Financial Reporting

In 2016, we identified material weaknesses regarding our internal control over financial reporting. For more information, see Item 3. Key
Information D. Risk FactorsWe have identified material weaknesses in our internal control over financial reporting, and if we cannot maintain effective internal control or provide reliable financial and other information
in the future, investors may lose confidence in the reliability of our consolidated financial statements, which could result in a decrease in the value of our ADSs. and Item 15. Controls and Procedures.

Engineering and Construction

The
principal driver of our E&C results is economic growth in Peru, particularly private and public investment in the countrys mining, power, oil and gas, transportation, real estate and other infrastructure sectors. See Peruvian
and Chilean Economic Conditions.

Appropriate pricing and budgeting of our engineering and construction projects is also key to our
results of operations in our E&C segment and can be affected by such factors as competition, direct negotiations with clients as opposed to competitive bidding processes, the accuracy of our estimation of project costs and unexpected cost
overruns. The types of contracts in this segment consist of cost-plus fee, unit price, lump-sum and EPC contracts. For a description of our E&C contracts, see Item 4.B. Information on the
CompanyBusiness OverviewEngineering and ConstructionContracts. The nature of our contractual arrangements can affect our margins, both because, depending on the type of contract, the burden of cost overruns may be placed on
the client or on us, and because certain contractual arrangements tend to have lower gross margins. For the years from 2014 to 2016, our E&C segment has trended towards more contractual arrangements based on costplus fee and EPC contracts.
The types of contractual arrangements we enter into in our E&C segment vary significantly from period to period.

During 2015, we
suffered losses of S/.138.2 million from a dispute with respect to an E&C contract with Hochschild Mining for the Inmaculada mining project, which affected our operating results. The dispute was terminated in August 2015, and we expect no
further losses to be incurred on account of this project. Additionally, we incurred losses for a total amount of S/.59.7 million because

of the cancellation of the El Nuble hydroelectric project, for which our subsidiary Vial y Vives was carrying on civil works in Chile. As a consequence of the cancellation of this project, we
also wrote down US$155 million of our consolidated backlog. We expect no further losses to be incurred on account of this project. Delays in obtaining payments from our E&C clients during 2015, in particular in the mining sector, increased
financing needs for working capital. We managed to stabilize working capital requirements by the end of 2015.

During 2016, we suffered
lower activity levels in our E&C segment due to the completion of two large mining projects at the end of 2015 (Las Bambas and Cerro Verde). These lower activity levels were not fully compensated by new works at the GSP gas pipeline project in
Peru and, to a lesser extent, works in Chile and Colombia. Additionally, Stracon GyM completed one mining services contract for our E&C segment, which was not renewed, and had another contract reduced in scope. The 2016 presidential elections in
Peru and the subsequent change in administration also contributed to lower activity levels in our E&C segment during 2016. Activity levels in our E&C segment remained low during 2017.

Infrastructure

Traffic and Fees for Toll Roads

The majority of our toll roads revenues derive from the Norvial concession. Unlike our other toll road concessions, our revenues from
the Norvial concession depend on traffic volume. Traffic volume on the Norvial road increased 6.6% from 2014 to 2015 and 7.1% from 2015 to 2016 (based on vehicle equivalents, as defined in Item 4.B. Information on the CompanyBusiness
OverviewInfrastructurePrincipal Infrastructure ActivitiesToll RoadsNorvial) and such increases are largely driven by economic activity levels in Peru. For the Norvial toll road, the toll rate is set out in the Norvial
concession agreement and adjusted in accordance with a contractual formula that takes into account the sol/U.S. dollar exchange rate and Peruvian and United States inflation. Under our Survial and Canchaque road concessions, our revenues consist of
annual fees paid by the Peruvian Ministry of Transport and Communications in consideration for the operation and maintenance of the roads, which can vary depending on the amount of road maintenance required due to road wear and tear.

Under the Norvial concession, we are required to expand certain stretches of the highway, by, among other things, adding two additional lanes.
The first stage of construction was completed in 2008 and the second stage started on April 2014 and is expected to be completed by July 2018 due to delays in the governments delivery of lands required for the project. We estimate that
Norvials capital investment for the second stage will be approximately US$95 million (S/.319.2 million).

Mass Transit

We generate revenue from our Lima Metro concession based on kilometers travelled per train, with the fee per kilometer, the number of trains
required to be in operation and the number of kilometers that we are required to travel established by the terms of the concession. Our revenues do not depend on passenger traffic volume. Our results in this concession between 2014 and 2016 were
influenced by the timely acquisition, set up, reliability and proper operation of our trains as well as by the timing of the governments completion of the 12.1 kilometer second stretch of Line One. We currently have all 24 trains in operation
(including two backup trains). In addition, the second tranche of Line One was completed in the third quarter of 2014. As of December 31, 2016, GyM Ferrovías has spent a total of US$196 million (S/.659 million) in capital
expenditures in connection with the Lima Metro.

On July 11, 2016, we entered into the fourth addendum to the Lima Metro concession
contract in order to expand the transportation capacity of Line One. In accordance with the fourth addendum, the expansion project involves: (i) the purchase of 20 new trains with five-car from
Alstom; (ii) the purchase of 39 new cars from Alstom, to be coupled with the 19 existing Alstom trains and 20 new Alstom trains, resulting in a consolidated fleet of 39 Alstom trains with a six-car
configuration; and (iii) the expansion and improvement of the existing infrastructure, including revamping and improvement of five stations, improvements in the electrical systems, a new access route to the maintenance workshop and new switches
on the main track.

Energy

A part of
the revenues in our Infrastructure segment depends on global prices for oil. Under our hydrocarbon extraction service contracts, we are entitled to a variable fee, which is based on the level of production of each field and a basket of international
crude oil prices. Under our contracts, we acquire the extracted hydrocarbons and pay royalties, which are also based on a basket of international crude prices and the level of production. Historically, oil prices have been volatile and are likely to
be volatile again in the future. During 2014, 2015 and 2016 average Brent crude prices were approximately US$99.02, US$52.46, and US$43.55 per barrel and the average fee we received in these years was US$77.33, US$45.59, and US$38.54 per barrel
of extracted oil, respectively. During the first quarter of 2018, the Brent crude price was approximately US$68.81 per barrel and our fee was approximately US$64.37 per barrel of extracted oil. Because our activities are conducted in mature oil
fields, which have been producing oil for over 100 years in the case of Block I, approximately 100 years in the case of Block III, approximately 95 years in the case of Block IV and for over 50 in the case of years Block V, our oil production
depends primarily on the level of our drilling and production activities.

Our Pariñas gas processing plant has a long-term delivery and gas processing and
fractionation contract with Empresa Eléctrica de Piura S.A. (EEPSA), a thermal power generation subsidiary of the Endesa group. Under this contract, EEPSA delivers natural gas that it purchases from onshore and offshore gas
producers in the Talara area. We are responsible for all operating costs of the gas processing plant but are entitled to keep revenues from the sale of all resulting natural gas liquids to third parties after delivery of all dry gas and payment of a
variable royalty to EEPSA. Approximately 75% of the total volume of natural gas processed by our Pariñas gas processing plant depend upon gas volumes demanded by EEPSA for its gas-fired turbines, which
can vary significantly. The other 25% of the volume of natural gas is extracted from our Block I. Prices for natural gas liquids can also fluctuate significantly and are affected by market prices for crude oil. We processed 27.3 MMcf per day during
2014, 31.7 MMcf per day during 2015 and 33.2 MMcf per day during 2016.These volumes vary per month and depend upon the power dispatch curve of EEPSA among Peruvian power generation plants. In rainy months (December to April) where
hydroelectric power generation in Peru is typically higher, gas volumes demanded by EEPSA are lower than in dryer months (May to November) in which activity of thermal generators tends to be higher.

In connection with our fuel storage terminal business, under three operation contracts with Petroperu, we receive revenues related to monthly
reserved volume in storage tanks for refined crude products (storage fee) and for volumes loaded and delivered into railroad cars or cistern trucks to each terminal (throughput fee). These fees are adjusted annually to account for U.S. inflation.
Our fuel storage activities in the North and Central terminals are carried out under 20-year contracts, which expire in 2034. Our contract for the operation of the South terminals was to expire in August 2017
but was extended for an additional year until August 2018.

Awarding and Timing of Infrastructure Concessions and Government Contracts

The results of operations of our Infrastructure segment are affected by our ability to win new concessions and government contracts, which
depend in part on government policies and our ability to compete effectively. As of December 31, 2016, we have seven concessions as well as long-term government contracts in this segment. These include the concession for Via Expresa Sur, for
which contract negotiations are currently stalled, and the concession for Chavimochic, for which Chavimochic has requested the termination of the concession in light of the governments failure to deliver the required lands for the project.
Joint operations in which we participate have been awarded one additional concession for Via Expresa Javier Prado for the expansion of another major highway within the city of Lima. We cannot assure you that we will be able to negotiate the pending
concessions on favorable terms or at all. A consortium led by Odebrecht Latinvest, in which we acquired a 20% stake in September 2015, was awarded the concession for the southern gas pipeline project in July 2014, however, the GSP gas pipeline
concession was terminated by the Peruvian Ministry of Energy and Mines on January 24, 2017. For more information, see Item 5.A. Operating and Financial Review and ProspectsOperating ResultsRecent Developments.

Our results in our Infrastructure segment are also affected by the timing of the commencement of operations under our concessions, as well as
when we were required to undertake significant capital investments or major construction works under the terms of our concessions. Under our Norvial and Lima Metro concessions, we are required to undertake capital investments during the initial
years of the concessions for which we are compensated throughout the term of the concessions by our toll rate in the case of the Norvial concession and tariffs in the case of the Lima Metro concession. Under our Survial, Canchaque and La Chira
concessions, we generate revenues in our Infrastructure segment from our construction activities during the pre-operational phase, and once operations commence we generate revenues from fees related to
operation and maintenance. Survial, Canchaque and La Chira have financed their construction costs through the sale of government certificates of construction to financial institutions at a discount from face value. Certificates of construction are
negotiable instruments that the Peruvian government typically delivers upon completion of each stage of a project and which entitle the holder to receive payment from the government equal to the capital investment made in the corresponding stage
upon completion of the entire project. Accordingly, the results of our Infrastructure segment may be affected by the discount rates obtained on the sale of government certificates of construction. For more information on our obligations and
compensation under our concessions, see Item 4.B. Information on the CompanyBusiness OverviewInfrastructure.

Real Estate

The results of operations of our Real Estate segment are driven by the number of units we develop and deliver in a reporting
period, our mix of unit sales (affordable housing versus housing), unit prices, land purchase prices and our costs of construction. These results are also affected by a number of factors that may impact the Peruvian real estate sector as a whole,
including: the availability of government subsidies for affordable housing; prices of suitable land in particular areas; regulation of real estate development imposed by national, regional and local laws and regulators, and the time required to
obtain applicable construction permits and licenses; the unemployment rate and wage levels; prevailing interest rates and availability of financing; the supply in the market; the level of customer interest in our new projects; and our costs, such as
the price of labor, materials, insurance, taxes and other public charges. We delivered 831, 835, and 934 units in 2014, 2015 and 2016, respectively.

##### Table of Contents

The results of operations of our Real Estate segment are also significantly affected by our sales
of land parcels. Due to the appreciation of land prices in Peru, and because we record our land holdings at book value (i.e., without marking to market), our recent land sales have resulted in high margins. Our board has approved the sale of non-strategic assets and, consequently, we have sold our interests in certain real estate projects as fully described in Item 5.A. Operating and Financial Review and ProspectsOperating
ResultsRecent Developments.

In addition, the net profit attributable to controlling interests of our Real Estate segment is
significantly affected by the financing and commercial arrangements we use to purchase land and to develop real estate projects. Depending on the level of non-controlling interests used to finance our real
estate projects, our Real Estate segment tends to have significant net profit attributable to non-controlling interests. See Results of OperationsGeneralReal Estate.

Technical Services

The results of
operations of our Technical Services segment, especially our activities relating to IT and electricity networks services, are affected by the economic growth of the countries in which we operate. As companies expand in response to economic growth,
they tend to outsource certain activities in order to focus on their core businesses.

Our results in the operation and maintenance of
infrastructure assets depend on our ability to obtain contracts from the government or infrastructure concessionaires, such as those in our Infrastructure segment, which depend on government policies and our ability to compete effectively. We had
one of the contracts with a regional government terminated in 2014, which impacted our results of operations for the year.In 2015, we obtained four new contracts (Sullana, La Merced, Iacapal and Bappo) and in 2016 two new contracts
(Chiquibambilla and Chincaypuijio) each with Provías Nacional. We typically obtain higher revenues from these contracts during the commencement of services as we bring the road to proper operating condition, and lower revenues at the end of
the contract term as services wind down.

Results of Operations

General

Accounting for Subsidiaries, Joint
Operations, Joint Ventures and Associated Companies

Results of our subsidiaries, joint operations, joint ventures and associated
companies are reflected in our financial results. We refer to our subsidiaries as those entities over which we exercise control. We consolidate the results of our subsidiaries in our financial statements and we reflect the profit corresponding to
the minority interests in our subsidiaries under profit attributable to non-controlling interests in our income statement. Our consolidation of the results of our subsidiaries include subsidiaries
in which we have less than 50% of the equity. We refer to business activities in which we share control with unrelated entities as joint arrangements, including joint operations and joint ventures, which are typically conducted through an agreement
with a third party to carry out specific projects. We contribute our assets to these projects and derive revenue from their use. In our financial statements we recognize, in relation to our interest in a joint operation, our assets and liabilities,
including our share of any asset or liability we hold jointly with our partner, as well as our share of revenue and expense from the joint operation. We refer to our associated companies as those entities over which we have significant influence but
do not control. We reflect the results of our associated companies and joint ventures under the equity method of accounting in our financial statements under the line item share of the profit and loss in associates in our income
statement. For further information, including a list of our subsidiaries, joint operations, joint ventures and associated companies, see notes 5a, 5c and 15 to our audited annual consolidated financial statements included in this annual report.

Intersegment Transactions

Some
of our segments from time to time provide services to our other segments. In 2016, we obtained 5.2% of the revenues in our E&C segment from the construction of La Chira waste water treatment plant and the second stage of the highway at Norvial
for our Infrastructure segment and the construction of real estate for our Real Estate segment; 37.7% of the revenues in our operation and

maintenance of infrastructure assets line of business derived from services provided to Norvial, Survial, Canchaque and the Lima Metro; and 6.6% of the revenues in our IT services line of
business derived from IT and outsourcing services provided to several of our other lines of businesses. Accordingly, in such circumstances, the segment providing services recognizes revenues and the segment receiving such services recognizes costs
of sales relating to the services provided. For example, in the case of La Chira, in which our E&C segment provides services to our Infrastructure segment, our E&C segment recognizes revenues and our Infrastructure segment recognizes costs
of sales with respect to the fees charged by our E&C segment for those services. In consolidation, these intersegment revenues and cost of sales are eliminated in our financial results. Nonetheless, our Infrastructure segment, in particular, may
recognize gross profits or losses based on the difference between the fees the segment charges in accordance with concession terms and costs it incurs relating to services provided by our other segments. For more information on our segments, see
note 7 to our audited annual consolidated financial statements.

Engineering and Construction

We obtain revenues in our E&C segment from the engineering and construction services we provide to our clients, which we recognize under
the percentage-of-completion method of accounting. For further information, see note 2.25 to our audited annual consolidated financial statements included in this annual
report. We receive unrestricted client advances in a substantial majority of our E&C projects, on average equal to approximately 12% of the contract price in 2016, which we record as an account payable. We typically invoice our clients on a
periodic basis as each project progresses, deducting from the related advances on a proportional basis. For further information, see note 21 to our audited annual consolidated financial statements included in this annual report. Our cost of sales in
our E&C segment includes labor, subcontractor expenses, materials, equipment, and project-specific general expenses.

Infrastructure

In our Infrastructure segment, we recognize revenues and cost of sales as follows:

(1) Toll Roads:



| |  |  | For Norvial, we obtain revenues for toll fees collected, minus deductions required to be transferred to the government as described in Item 4.B. Information on the CompanyBusiness
OverviewInfrastructurePrincipal Infrastructure ActivitiesToll RoadsNorvial, which we recognize upon receipt. Cost of sales for Norvial include fees paid to third parties (primarily our subsidiary Concar) for operation
and maintenance services as well as the amortization of the road concession registered as an intangible asset in our financial statements; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | For Survial and Canchaque, we obtain revenues for routine and periodic maintenance services, which we recognize in the period in which the services are performed. Cost of sales for Survial and Canchaque include fees
paid to third parties (primarily our subsidiary Concar) for operation and maintenance services. We do not recognize the Survial and Canchaque concessions as intangible assets and therefore do not amortize the concessions.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For further information, see notes 2.16(c) and 17to our audited annual consolidated financial statements included in this
annual report.

(2) Mass Transit: We obtain revenues from our Lima Metro concession based on a tariff per kilometer traveled by our trains
in operation in accordance with a schedule established in our concession agreement, which we recognize in the period in which the services are performed. Under the concession, the tariff is comprised of three components: (i) fees related to our
operation and maintenance services; (ii) fees related to the Peruvian governments repayment of the amounts we invest to purchase trains, ongoing capital expenditures and other infrastructure for the Peruvian government; and
(iii) fees related to interest we charge to the Peruvian government in connection with the amounts we invest to purchase such trains, ongoing capital expenditures and other infrastructure. In 2016, the fees related to items (i), (ii) and
(iii) were S/.166.1 million, S/.9.4 million and S/.42.4 million, respectively. We only recognize in our income statement the portion of the tariff that relates to items (i) and (iii) We record the amounts paid by us that
relate to item (ii) as long-term accounts receivables from the Peruvian government. Accordingly, tariff payments received relating to item (ii) reduce our accounts receivables but do not impact our income statement, and we do not amortize
our investments in our income statement as our investment in the concession is recorded as an account receivable with the government rather than a depreciable investment.

We entered into the fourth addendum to the Lima Metro concession contract on July 11, 2016, in order to expand transportation
capacity. In accordance with the fourth addendum, the expansion project will involve: (i) the purchase of 20 new trains; (ii) the purchase of 39 new cars; and (iii) the improvement and expansion of the existing infrastructure. As
compensation for the investments of the expansion project, we will be entitled to receive the following: (i) an advance payment of 30% of each investment component; and (ii) the balance of 70% of each investment component, compensated
through the annual payment for additional investments (pago anual por inversiones complementarias). We register the estimated compensation related to the direct cost in the income statement, plus a margin in the same period. In 2016, the
income related to the investment components was S/.32.1 million.

##### Table of Contents

For further information, see note 10 to our audited annual consolidated financial statements
included in this annual report. Cost of sales for the Lima Metro include fees paid to third parties (primarily our E&C segment, our subsidiary Concar and other subcontractors) for construction and operation and maintenance services, energy, and
our financing costs related to the purchase of trains.

(3) Water Treatment: We obtain revenues from the engineering design and
construction of La Chira waste water treatment plant, which we recognize based on the percentage-of-completion method of accounting. Once the plant began operating in
August 2016, we obtain revenues only for operation and maintenance services, which we recognize in the period in which the services are performed. During the construction phase, cost of sales for La Chira included fees paid to third parties,
primarily our E&C segment, for engineering and construction services. During the operation phase, cost of sales for La Chira include personnel charges and maintenance of infrastructure.

(4) Energy: We obtain revenues from extraction services and license contracts related to oil and gas production, fuel storage services, and the
sale of natural gas liquids derived from our gas processing and fractionation services, which we recognize in the period in which the services are performed and, in the case of sale of natural gas liquids, when the sale is made. Cost of sales for
our energy line of business includes labor, materials, amortization of oil wells, depreciation of the gas plant, maintenance and general expenses.

Real Estate

We obtain revenues in our
Real Estate segment from sales of affordable housing and housing units, commercial buildings and land parcels, which we recognize at the time of delivery of the unit or building and, in the case of land parcels, at the time of the sale. We typically
pre-sell our affordable housing and housing units prior to and during construction, and use the related proceeds we receive to finance the construction of the units. These
pre-sale funds are restricted and released from escrow to us periodically as construction progresses. Our Real Estate cost of sales includes the cost to purchase land, costs of architectural design and
construction (which usually includes payments to third parties, primarily our E&C segment), licensing and permit costs, personnel costs, and fees to third parties related to sanitation or electrical engineering. In 2016, our cost of land that is
allocated to units delivered during these periods amounted to S/.45 million. We recognize land purchases as inventory, and, accordingly, do not mark-to-market the
value of our land for changes in fair value. For further information, see note 14 to our audited annual consolidated financial statements included in this annual report.

In our Real Estate segment, we have significant net profit attributable to non-controlling interests.
We hold a significant portion of our land bank through Almonte in which we have a 50.4% interest, and we consolidate Almontes results in our financial statements. In addition, we undertake a significant number of our real estate projects
through entities in which we may have a majority interest, co-equal interest or minority interest; when we have control over these entities, we consolidate their results in our financial statements regardless
of whether we own a majority of the capital. Furthermore, in connection with our affordable housing projects, we generally partner with real estate investment funds and insurance companies that provide between 60% and 70% of the total capital
required to purchase the land and cover certain pre-construction costs in exchange for equity in the project. Although we typically own a minority interest in these projects, we consolidate their results in
our financial statements because we exercise control over the project. Accordingly, we reflect the profit corresponding to our real estate partners under net profit attributable to non-controlling interests in
our income statement. See Accounting for Subsidiaries, Joint Operations, Joint Ventures and Associated Companies.

Technical Services

In our Technical Services segment, we recognize revenues and cost of sales as follows:

(1) Operation and Maintenance of Infrastructure Assets: We obtain revenues from our operation and maintenance of infrastructure assets line of
business for the operation and maintenance services we provide to the government and concessionaires (currently concessions within our Infrastructure segment), which we recognize in the period in which the services are performed. We receive
unrestricted advances with respect to our service contracts with the government, that vary from approximately 10% to 30% of the contract price, which we record as an account payable. We typically invoice our clients on a periodic basis as the
project progresses, deducting from the related advances on a proportional basis. For further information, see note 21 to our audited annual consolidated financial statements included in this annual report. Our cost of sales in this line of business
includes personnel costs, services provided by third parties, machinery and other materials (primarily trucks), and depreciation of equipment utilized to provide services. Beginning on April 1, 2017, we have transferred Concar from our
Technical Services segment to our Infrastructure segment.

(2) IT Services: We obtain revenues from our IT services line of business for IT and outsourcing
services we perform for government and private sector clients, which we recognize in the period in which the services are performed. Our IT services cost of sales includes personnel costs, services provided by third parties, equipment and other
materials, depreciation of equipment utilized to provide services, and amortization of software.

(3) Electricity Networks
Services: We obtain revenues from the electrical services we provide to our clients, which we recognize in the period in which the services are performed. Our cost of sales in this line of business includes personnel costs, services provided by
third parties, machinery and other materials (primarily trucks and meters), and depreciation of equipment utilized to provide services.

Revenues

Our total revenues decreased by 17.2%, or S/.1,345.9 million, from S/.7,815.5 million for 2015 to S/.6,469.6 million for 2016.
Revenues decreased due mainly to lower revenues in our E&C segment as a result of the completion of two large mining projects at the end of 2015 (Las Bambas and Cerro Verde), which were not fully compensated by new works at the GSP project in
Peru and, to a lesser extent, works in Chile and Colombia. The 2016 presidential elections in Peru and the subsequent change in administration also contributed to lower activity levels in our E&C segment during 2016. Additionally, Stracon GyM
completed one mining services contract for our E&C segment, which was not renewed, and had another contract reduced in scope. On the other hand, in the Infrastructure segment, revenues decreased mainly due to the timing of works on the second
stage of the Norvial toll road and lower amount of maintenance works on the Survial highway. This reduction is partially offset by: the increase in revenues in the Real Estate segment, which is the result of the sale of land in Almonte for
S/.97.0 million in 2016 compared to S/.12.0 million in 2015, as well as by more units delivered in 2016 (938 units versus 835 units in the previous year), and the increase in revenues of the Technical Services segment due to the
consolidation of Adexus acquisition as of August 2016 and higher revenues in CAM for the new contracts awarded during the year.

Cost of Sales

Our total cost of sales decreased by 18.1%, or S/.1,299.3 million, S/.7,165.5 million for 2015 to S/.5,866.2 million for 2016.
This decrease is mainly due to the reduction of revenues.

Gross Profit

Our gross profit decreased by 7.2% or S/.46.6 million, from S/.650.0 million for 2015 to S/.603.4 million for 2016. Our gross
margin (i.e. gross profit as a percentage of revenues) for 2016 was 9.3% compared to 8.3% for 2015. In 2015 gross profit was impacted by losses incurred from a dispute with respect to an E&C contract with Hochschild Mining for the Inmaculada
mining project and losses incurred because of the cancellation of the El Nuble hydroelectric plant project, for which our subsidiary Vial y Vives was carrying on civil works in Chile. In 2016, gross profit was impacted by the early termination of
GSP construction consortium in our E&C segment and partially offset by the profit generated by the sale of land of Almonte in our Real Estate segment. During 2016, gross profit was also impacted in our Infrastructure segment by the decrease in
oil price.

The following table sets forth a breakdown of our gross profit by segment for 2015 and 2016.

Administrative Expenses

Our administrative expenses decreased by 3.4%, or S/.14.0 million, from S/413.4 million for 2015 to S/.399.4 million for 2016.
This decrease is mainly due to a reduction in services provided by third parties principally relating to legal, accounting and tax consultancy. As a percentage of revenues, our administrative expenses increased to 6.2% in 2016 from 5.3% in
2015.

Other Income (Expenses)

Our other income (expenses) decreased by 122.0%, or S/.70.0 million, from S/.57.4 million in income for 2015 to S/.12.6 million
in expenses for 2016. In 2015 our other income included the reversion of tax and labor provisions in connection with the acquisition of CAM, the sale of machinery, equipment and scrap and dividend payments from our subsidiary TGP, and in 2016, our
other income included the sale of machinery and equipment, price adjustments as well as a reversion of legal and tax provisions in connection with the acquisition of Morelco, and extraordinary income from the settlement agreement reached in
connection with the legal proceeding related to the Collahuasi project in Chile.

Revenues. Our E&C revenues decreased 28.6%, or S/.1,669.9 million, from
S/.5,829.4 million for 2015 to S/.4,159.5 million for 2016. This decrease is the result of the completion of two large mining projects at the end of 2015 (Las Bambas and Cerro Verde), which were not fully compensated by the works at the
GSP project in Peru and, to a lesser extent, works in Chile and Colombia. Additionally, Stracon GyM completed one mining services contract for our E&C segment, which was not renewed, and had another contract reduced in scope. The 2016
presidential elections in Peru and the subsequent change in administration also contributed to lower activity levels in our E&C segment during 2016.

The following tables set forth variations in our E&C revenues by business activities, types of contracts and end-markets:

The breakdown of E&C revenues by different business activities, types of contracts and end-markets tends to vary from period to period due to a variety of factors, including the timing of the execution of larger projects in any particular period, which is typically outside of our control.

Gross Profit. Our E&C gross profit decreased 28.2%, or S/.88.2 million, from S/.312.8 million for 2015 to
S/.224.6 million for 2016. Our E&C gross margin for 2015 was 5.4% and for 2016 was 5.4% as well. The decrease in our E&C gross profit was mainly due to a decline in revenues and the impact of the early termination of the GSP
construction consortium.

Operating Profit. Our E&C operating profit decreased 179.7%, or S/.97.4 million, from
S/.54.2 million profit for 2015 to S/.43.2 million loss for 2016, due to reduction of gross profit, partially offset by the decrease in administrative expenses, related to a reduction of personnel and lower expenses relating to bid
proposals. Our E&C operating margin was 1.0 for 2016 compared to 0.9% for 2015.

Other income (expenses). Other income
(expenses) increased in our E&C segment, from S/.30.8 million income for 2015 to S/.9.2 million in expenses in 2016, mainly as a result of the settlement agreement reached in connection with the legal proceeding related to the
Collahuasi project in Chile and the reversion of legal and tax provisions in connection with the acquisition of Morelco.

In addition, our E&C segment had S/.5.7 million in expenses in 2016, compared to
S/.9.3 million in income in 2015, relating to minority interests held by Vial y Vives in several of its projects undertaken in Chile, as well as the minority participation of GyM in Viva GyM reflected under share of profit and loss in
associates in our audited annual consolidated financial statements.

Our Infrastructure revenues decreased 10.4% or S/.106.2 million, from S/.1,018.3 million for 2015 to
S/.912.1 million for 2016. The variation in our Infrastructure revenues principally reflected the following:



| |  |  | Toll Roads: a 33.0%, or S/.130.1 million, decrease in revenues, from S/.394.5 million for 2015 to S/.264.4 million for 2016, primarily due to the timing of the work for the second stage of the
Norvial toll road and a decrease in revenues in Survial due to less maintenance executed on the road;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Mass Transit: a 19.6%, or S/.40.5 million, increase in revenues, from S/.206.5 million for 2015 to S/.247.0 million for 2016, primarily due to the revenues recognized for the advance of the
construction of the infrastructure expansion;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Water Treatment: a 33.9%, or S/.9.5 million, decrease in revenues, from S/.28.0 million for 2015 to S/.18.5 million for 2016, primarily due to conclusion of the construction works of the La Chira
waste water treatment plant. The operation of the plant started in the second quarter of 2016; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Energy:a 1.8%, or S/.7.2 million, decrease in revenues, from S/.389.4 million for 2015 to S/.382.2 million for 2016, primarily due to a reduction in our barrel daily production (2,756 barrel daily
production in 2016 versus 3,356 in 2015), as well as a decrease in international oil prices (average price per basket of oils of US$41.8 bbl in 2016 versus US$50.9 bbl in 2015), partially offset by better results in our fuel terminals business (3.18
MM barrels in storage per month in 2016 versus 3.12 MM barrels in storage in 2015, and 3.34 MM barrels dispatched per month in 2016 versus 3.19 MM barrels dispatched per month in 2015), the fact that operations in Blocks III and IV commenced in
April 2015 and higher processing levels at our gas processing plant which increased from 31.7 MMcf per day in 2015 to 33.2 MMcf per day in 2016.

Our Infrastructure gross profit decreased 10.1%, or S/.18.6 million, from
S/.184.7 million for 2015 to S/.166.1 million for 2016. Our Infrastructure gross margin was 18.2% for 2016 compared to 18.1% for 2015. The variation in our Infrastructure gross profit principally reflected the following:



| |  |  | Toll Roads:a 3.4%, or S/.2.7 million, decrease in gross profit, from S/.78.5 million for 2015 to S/.75.8 million for 2016. Even though the gross profit decreased, due to the lower construction
activities in Norvial, our Toll Roads gross margin increased from 19.9% for 2015 to 28.7% for 2016, as a consequence of a lesser impact on gross profit from lower construction activities in Norvial, because these activities have lower margins;

Our Infrastructure operating profit decreased 14.5%, or S/.21.2 million, from S/.146.8 million for
2015 to S/.125.6 million for 2016. Our Infrastructure operating margin was 13.8% for 2016 compared to 14.4% for 2015. The variation in our Infrastructure operating profit principally reflected the following:



| |  |  | Toll Roads:a 3.8%, or S/.2.6 million, decrease in operating profit, from S/.68.3 million for 2015 to S/.65.7 million for 2016, primarily due to the decrease in gross profit given that

Revenues. Our Real Estate revenues increased 90.7%, or S/.195.7 million, from
S/.215.8 million for 2015 to S/.411.5 million for 2016. The increase is primarily due to the sale of land in Almonte for S/.97.0 million in 2016, compared to S/.12.0 million from land sales in 2015, as well as more units
delivered in 2016 (938 units in 2016 and 835 units in 2015).

Gross Profit. Our Real Estate gross profit increased 163.5%, or
S/.84.7 million, from S/.51.8 million for 2015 to S/.136.5 million for 2016, mainly as a result of the sale of land in Almonte, partially offset by lower margins in units delivered in 2016, specifically the Rancho project, compared to
2015, when more housing units with higher margins were delivered. Our Real Estate gross margin was 33.2% for 2016 compared to 24.0% for 2015.

Operating Profit. Our Real Estate operating profit increased 230.0%, or S/.75.9 million, from S/.33.0 million for 2015 to
S/.108.9 million for 2016, primarily as a result of the increase in our gross profit partially offset by an increase in administrative expenses due to write-offs of pre-operational costs for projects that
were not executed.

Our Technical Services operating profit decreased 18.8%, or S/.13.2 million, from S/.70.3 million
for 2015 to S/.57.1 million for 2016. Our Technical Services operating margin for 2016 was 4.1% compared to 6.1% for 2015. The variation in our Technical Services operating profit principally reflected the following:



| |  |  | Operation and Maintenance of Infrastructure Assets: a S/.13.4 million decrease in operating profit, from a S/.34.0 million profit for 2015 to a S/.20.6 million profit for 2016, primarily due to the
decrease in gross profit. Our Operation and Maintenance of Infrastructure Assets operating margin was 7.8% for 2016 compared to 10.2% for 2015;

Financial (Expense) Income, Net

Our net financial expense increased S/.72.1 million from net financial expenses of S/.138.7 million in 2015 to net financial expenses
of S/.210.8 million in 2016. Excluding foreign exchange differences, our net financial expense increased 255.4%, or S/.142.5 million, from net financial expenses of S/.55.8 million for 2015 to net financial expenses of
S/.198.3 million for 2016 due to the interest paid on our syndicated loan and a discount of the long term account receivable related to the termination of the GSP gas pipeline concession. Our net exchange difference decreased
S/.70.4 million, from a loss of S/.82.9 million for 2015 to a loss of S/.12.5 million for 2016. This decrease is due to the appreciation of the sol against the U.S. dollar from 2015 to 2016.

Share of Profit and Loss in Associates

Our share of profit and loss in associates decreased S/.597.4 million from a profit of S/.7.7 million in 2015 to a loss of
S/.589.7 million in 2016. This decrease is primarily due to the impairment of our investment in GSP as a consequence of the cancellation of the concession on January 24, 2017. For more information, see Item 5.A. Operating and
Financial Review and ProspectsOperating ResultsRecent Developments.

Income Tax

Our income tax decreased 212.9%, or S/.210.8 million, from S/.(99.0) million for 2015 to S/.111.8 million for 2016. This decrease in
income tax was primarily due to a decrease in profit before tax. Our effective tax rates for 2016 and 2015 were (19.8)% and 64.0%, respectively.

Net Profit

Our net profit
decreased S/.507.3 million, from S/.55.6 million profit for 2015 to a S/.451.7 million loss for 2016. Net profit attributable to controlling interests decreased S/.516.8 million, while net profit attributable to non-controlling interests increased S/9.6 million. Net profit attributable to non-controlling interests increased primarily due to our Real Estate segment. See

Revenues

Our total revenues increased by 11.5%, or S/.806.8 million, from S/.7,008.7 million for 2014 to S/.7,815.5 million for 2015.
This increase was due mainly to growth in our E&C segment, primarily due to the acquisition of Morelco in December 2014 and the increase in electromechanic construction and contract mining services activities, and in our Infrastructure segment,
primarily due to higher revenues of Norvial, the increase of trains in operation in the Lima Metro, and the commencement of operations in Blocks III and IV in April 2015 in GMP.

The following table sets forth a breakdown of our revenues by segment for 2014 and 2015.

Cost of Sales

Our total cost of sales increased by 18.3%, or S/.1,108.4 million, S/.6,057.1 million for 2014 to S/.7,165.5 million for 2015.
This increase was related to the growth in our revenues as well as in our E&C segment, an increase in cost in certain civil construction projects, losses incurred from a dispute with respect to an E&C contract with Hochschild Mining for the
Inmaculada mining project and losses incurred because of the cancellation of the El Nuble hydroelectric project, for which our subsidiary Vial y Vives was carrying on civil works in Chile.

Gross Profit

Our gross profit
decreased by 31.7%, or S/.301.6 million, from S/.951.6 million for 2014 to S/.650.0 million for 2015. Our gross margin (i.e., gross profit as a percentage of revenues) for 2015 was 8.3% compared to 13.6% for 2014. This decrease in our
gross margin was mainly due to lower gross margins in our E&C segment, primarily due to lower margins in certain civil construction projects and our Real Estate segment, primarily due to lower margins in the units delivered and the lower number
of units. In 2015 our E&C margins were impacted by losses incurred from a dispute (errors in the engineering, which led to reworks and extension of the term of the project which carries out more general expenses) with respect to an E&C
contract with Hochschild Mining for the Inmaculada mining project and losses incurred because of the cancellation of the El Nuble hydroelectric plant project, for which our subsidiary Vial y Vives was carrying out civil works in Chile. These two
contracts were lump-sum contracts. As of December 2015, both projects have been completed, therefore all the impact was registered that year.

Administrative Expenses

Our administrative expenses decreased by 1.9%, or S/.8.0 million, from S/.421.4 million for 2014 to S/.413.4 million for 2015,
primarily due to the decrease of administrative expenses in the Technical Services segment, specifically in CAM and GMD. As a percentage of revenues, our administrative expenses decreased to 5.3% in 2015 from 6.0% in 2014.

Other Income (Expenses)

Our other
income (expenses) increased S/.42.2 million, from S/.15.1 million for 2014 to S/.57.4 million for 2015. This increase was primarily due to an increase in our E&C segment, from a S/.9.8 million loss to a S/.30.8 million
profit as a result of a gain on the fair value of the liability for a put option related to the Morelco acquisition in 2014, the reversal of provisions in connection with the CAM acquisition, the dividends received from TGP and the sale of certain
machinery and equipment.

Operating Profit

Our operating profit decreased 47.6% or S/.259.7 million, from S/.545.3 million for 2014 to S/.285.6 million for 2015. Our
operating margin (i.e., operating profit as a percentage of revenues) was 3.7% for 2015 compared to 7.8% for 2014. This decrease is primarily due to the decrease in gross profit, partially offset by our decrease in administrative expenses and our
increase in other income (expenses). The following table sets forth a breakdown of our operating profit by segment for 2014 and 2015.

Revenues. Our E&C revenues increased 15.8%, or S/.793.7 million, from S/.5,035.7 million
for 2014 to S/.5,829.4 million for 2015, primarily due to the acquisition of Morelco in December 2014 and the growth in revenues in our electromechanic and contract mining activities.

##### Table of Contents

The breakdown of E&C revenues by different business activities, types of contracts and end-markets tends to vary from period to period due to a variety of factors, including the timing of the execution of larger projects in any particular period, which is typically outside of our control.

Gross Profit. Our E&C gross profit decreased 41.6%, or S/.222.6 million, from S/.535.4 million for 2014 to
S/.312.8 million for 2015. Our E&C gross margin for 2015 was 5.4% compared to 10.6% for 2014. The decrease in gross profit was due to losses incurred from a dispute (errors in the engineering, which led to reworks and extension of the term
of the project which carries out more general expenses) with respect to an E&C contract with Hochschild Mining for the Inmaculada mining project and losses incurred because of the cancellation of the El Nuble hydroelectric plant project, for
which our subsidiary Vial y Vives was carrying out civil works in Chile. As of December 2015, both projects have been completed, therefore all the impact was register that year.

Operating Profit. Our E&C operating profit decreased 79.7%, or S/.212.8 million, from S/.267.0 million for 2014 to
S/.54.2 million for 2015. Our E&C administrative expenses decreased 11.8%, or S/.30.6 million, which resulted in administrative expenses as a percentage of revenues of 5.0% for 2015 compared to 5.1% for 2014, due mainly to a decrease
in the administrative expenses of GyM. Our E&C operating margin for 2015 was 0.9% compared to 5.3% for 2014.

In addition, our E&C
segment had S/.12.9 million in profit from minority interests held by Vial y Vives in several of its projects undertaken in 2015 in Chile, as well as the minority participation of GyM in Viva GyM reflected under share of profit and loss
in associates in our audited annual consolidated financial statements.

Our Infrastructure revenues increased 15.1% or S/.133.5 million, from S/.884.8 million for 2014 to
S/.1,018.3 million for 2015. The variation in our Infrastructure revenues principally reflected the following:



| |  |  | Toll Roads: a 16.6%, or S/.56.3 million, increase in revenues, from S/.338.2 million for 2014 to S/.394.5 million for 2015, primarily due to the recognition of the work progress for the second
stage of the Norvial toll road partially offset by a decrease in revenues in Survial.;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Mass Transit: a 23.7%, or S/.39.5 million, increase in revenues, from S/.167.0 million for 2014 to S/.206.5 million for 2015, primarily due to the increase of trains in operation from 14 trains at
the beginning of 2014 to 24 trains (including the backup trains) in September 2014;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Water Treatment: a 4.4%, or S/.1.3 million, decrease in revenues, from S/.29.3 million for 2014 to S/.28.0 million for 2015, primarily due to slower progress in the construction of the La Chira
waste water treatment plant due to anomalous water movements; and

| |  |  | Energy:a 11.2%, or S/.39.1 million, increase in revenues, from S/.350.3 million for 2014 to S/.389.4 million for 2015, primarily due to a 65.8% growth in our barrel daily production (2,910
barrel daily production in 2015 versus 1,755 in 2014) resulting from the commencement of operations in Blocks III and IV in April 2015, despite a decrease in international oil prices (average price per basket of oils of US$52.4 bbl in 2015 versus
US$97.1 bbl in 2014), in addition to higher processing levels at the our gas processing plant which increased from 27.6 MMcf per day in 2014 to 31.6 MMcf per day in 2015.

Our Infrastructure gross profit decreased 24.8%, or S/.60.8 million, from S/.245.6 million for 2014
to S/.184.8 million for 2015. Our Infrastructure gross margin was 18.1% for 2015 compared to 27.8% for 2014. The variation in our Infrastructure gross profit principally reflected the following:



| |  |  | Toll Roads:a 2.4%, or S/.1.8 million, increase in gross profit, from S/.76.7 million for 2014 to S/.78.5 million for 2015. This increase was primarily due to the increase in revenues from Norvial,
partially offset by a decrease in gross profit in Survial. Our Toll Roads gross margin was 19.9% for 2015 compared to 22.7% for 2014, primarily due to the recognition of revenues from construction activities in Norvial which have lower margins and
impact the overall margins in Toll Roads;

Our Technical Services operating profit increased 173.7%, or S/.44.6 million, from
S/.25.7 million for 2014 to S/.70.3 million for 2015. Our Technical Services operating margin for 2015 was 6.1% compared to 2.1% for 2014. The variation in our Technical Services operating profit principally reflected the following:



| |  |  | Operation and Maintenance of Infrastructure Assets: a S/.56.4 million increase in operating profit, from a S/.22.4 million loss for 2014 to a S/.34.0 million profit for 2015, primarily due to a
higher gross profit and lower administrative expenses. Our Operation and Maintenance of Infrastructure Assets operating margin was 10.2% for 2015 compared to (6.1)% for 2014;

| |  |  | IT Services: a 4.7%, or S/.0.7 million, increase in operating profit, from S/.15.8 million for 2014 to S/.16.5 million for 2015, primarily due to lower administrative expenses. Our IT Services
operating margin was 6.5% for 2015 compared to 6.4% for 2014; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Electricity Networks Services: a 38.7%, or S/.12.5 million, decrease in operating profit, from S/.32.3 million for 2014 to S/.19.8 million for 2015, primarily due to lower margins in projects in
Chile and Colombia and termination of certain contracts and lower reversal of provisions in 2015 (S/.9.4 million) than in 2014 (S/.7.8 million) in connection with the CAM acquisition which offset the increase in gross profit between the two periods.
Our Electricity Network Services operating margin was 3.5% for 2015 compared to 5.4% for 2014.

Financial (Expense) Income, Net

Our net financial expense increased S/.47.3 million from net financial expenses of S/.91.4 million in 2014 to net
financial expenses of S/.138.7 million in 2015. This increase is a consequence of the increase of the working capital debt in the E&C area throughout the year due to delays in obtaining payments from our E&C clients during 2015, in
particular in the mining sector. Excluding foreign exchange differences, our net financial expense decreased 18.5%, or S/.8.7 million, from net financial expenses of S/.47.1 million for 2014 to net financial expenses of
S/.55.8 million for 2015. Our net exchange difference increased S/.38.6 million, from a loss of S/.44.3 million for 2014 to a loss of S/.82.9 million for 2015. This increase is due to both the depreciation of the sol against the
U.S. dollar from 2014 to 2015, partially offset by the replacement of dollar-denominated debt with soles denominated debt.

Share of Profit and Loss
in Associates

Our share of profit and loss in associates decreased S/.45.7 million from a profit of S/.53.4 million in
2014 to a profit of S/.7.7 million in 2015. This decrease is primarily due to lower profits generated in projects where Vial y Vives DSD, Viva GyM and CAM have minority participation and are not consolidated.

Income Tax

Our income tax
decreased 32.3%, or S/.47.2 million, from S/.146.2 million for 2014 to S/.99.0 million for 2015. This decrease in income tax was primarily due to a decrease in profit before tax. Our effective tax rates for 2015 and 2014 were 64.0%
and 28.8%, respectively.

Net Profit

Our net profit decreased 84.6%, or S/.305.5 million, from S/.361.1 million for 2014 to S/.55.6 million for 2015. Net profit
attributable to controlling interests decreased 97.6%, while net profit attributable to non-controlling interests decreased 21.1%. Net profit attributable to
non-controlling interests decreased primarily due to our E&C and Real Estate segments. See GeneralAccounting for Subsidiaries, Joint Operations, Joint Ventures and Associated
Companies.

B. Liquidity and Capital Resources

Our principal sources of liquidity have historically been cash flows from operating activities and, to a lesser extent, equity capitalization
and indebtedness. We conducted an initial public offering of ADSs in July 2013 from which we received approximately US$411.3 million in net proceeds. During 2015 we entered into a medium term loan credit agreement for up to US$200 million
(S/.672 million) with Credit Suisse and our subsidiaries GyM Ferrovías and Norvial issued bonds for S/.629 million (US$184.3 million) and S/.365 million (US$106.9 million), respectively.

As a result of the termination of the GSP gas pipeline concession, we have renegotiated three
debt instruments as follows: (i) we amended the terms of our syndicated loan related to our equity investment in GSP; (ii) we repaid our proportional guarantee of the GSP bridge loan and entered a new term loan in a principal amount of
US$78.7 million (S/.264.8 million); and (iii) we amended the terms of our proportional repayment obligations under the GSP performance guarantee. In order to strengthen our liquidity and financial flexibility, particularly in the event of
potential delays in receiving the government payment contemplated under the GSP gas pipeline concession contract, and make payments on our debt related to the GSP project, our board has approved the sale of
non-strategic assets in the amount of up to US$350 million (S/.1,176 million) in proceeds. For more information, see Item 5.A. Operating and Financial Review and ProspectsOperating
ResultsRecent Developments.

Our principal uses of cash (other than in connection with our operating activities) have
historically been: capital expenditures in all our business segments, including acquisitions and investments in our infrastructure concessions; servicing of our debt; and payment of dividends. We believe that these sources of cash will be sufficient
to cover our working capital needs in the ordinary course of business. We believe that our cash from operations, our current financing sources and the sale of non-strategic assets, as described in Item
5.A. Operating and Financial Review and ProspectsOperating ResultsRecent Developments, are sufficient to satisfy our current capital expenditures and debt service obligations through the next 12 months.

We had credit lines with various financial institutions for a total amount of US$2,877.4 million as of December 31, 2016 and for a
total amount of US$2,659.9 million as of December 31, 2015. Our available lines of credit as of December 31, 2017 totaled US$1,427.33 million. However, our banks have currently restricted us from taking out further lines of
credit to finance new operations. See Recent Developments Emergency Decree and Subsequent Legislation.

We are currently
in default of certain of the covenants under these financial instruments. For more information, see Item 13. Defaults, Dividend Arrearages and Delinquencies.

At December 31, 2016, our cash and cash equivalents totaled S/.606.9 million (US$180.6 million), of which S/.16.2 million
(US$4.8 million) was held by our foreign subsidiaries. We currently intend to distribute these funds to our company to the extent we believe they are not required for the local operations. We are not currently required to accrue or pay any material
taxes associated with the repatriation of these funds. In addition, our foreign subsidiaries have no contractual restrictions, and we are not aware of any material legal restrictions, on their ability to transfer funds to us in the form of cash
dividends, loans or advances.

Cash Flows

The table below sets forth certain components of our cash flows for 2014, 2015 and 2016.

Cash Flow from Operating Activities

Net cash flow used in operating activities in 2016 was lower than in 2015. For 2016 this reflects a reduction in the account receivables in the
E&C segment mainly explained by the termination of two significant mining projects to the end of 2015.

Net cash flow used in
operating activities in 2015 was higher than in 2014. For 2015 this reflects an increase in accounts payable, other accounts receivables, account receivables from related parties and inventory, mainly related to the proportional consolidation of the
GSP construction consortium, and the advances of work of the expansion of Norvials Toll Road.

Cash Flow from Investing Activities

Net cash flow used in investing activities in 2016 was lower than in 2015. In 2016 we continued with the equity contribution to the GSP
consortium.

Net cash flow used in investing activities in 2015 was higher than in 2014. This mainly reflects the purchase of a 20% stake
in the GSP consortium.

Cash Flow from Financing Activities

Net cash flow provided by financing activities in 2016 was lower than in 2015. This is primarily due to a reduction of indebtedness in our
E&C segment due to the collection of account receivables and a reduction of debt in the Real Estate segment due to more projects in execution, with sufficient cash flows to repay their debt, partially offset by an increase in the Infrastructure
and Technical Services segments, mainly due to the increase in the Norvial bond and consolidation of Adexus. Additionally, in 2016 less dividends were paid and there was an increase in the participation of Vial y Vives DSD.

Net cash flow provided by financing activities in 2015 was higher than in 2014. This is primarily due to a 60.0% increase in the loans
received because of higher levels of indebtedness in our E&C segment.

As of December 31, 2017, S/.808.5 million (US$240.6 million) of our total indebtedness indicated in the table above has matured, of
which S/.562.1 million (US$167.3 million) was repaid and S/.246.4 million (US$73.3 million) was renewed by extending the maturities. The weighted average interest rate of this renewed indebtedness and additional indebtedness was 4.8% and
the maturity dates ranged from January 5, 2018 to December 18, 2019.

In June 2017, we renegotiated the terms of our syndicated
loan and our obligations with respect to the GSP bridge loan and the GSP performance guarantee. In July 2017, we entered into a financial stability framework agreement providing for new lines of credit.

Below is a description of our material outstanding indebtedness as of December 31, 2016. As of such date, we were not in compliance with
certain of the financial covenants related to our syndicated loan. We subsequently entered into an amendment of the syndicated loan, which modified the effective date of compliance with the covenants. However, as of the date of this annual report,
we were in continuing default under the syndicated loan and certain of our other debt instruments due to, among other things, the delay in furnishing the companys 2016 audited consolidated financial statements. See Item 5.A. Operating
and Financial Review and ProspectsOperating ResultsRecent Developments, and Item 13. Defaults, Dividends, Arreages and Delinquencies.

Leasing. As of December 31, 2016, we were party to numerous leasing agreements with several financial institutions which in the
aggregate amounted to approximately S/.246.8 (US$73.5 million).We entered into such agreements primarily for the purpose of leasing the equipment and other assets necessary to run our operations. Upon maturity of each leasing
agreement, we have the option to purchase or return the equipment or assets to the lessor. The amounts owed under these leasing agreements are generally repaid in monthly installments, subject to a minimum guaranteed payment corresponding to the
minimum amount for which the equipment or assets could be sold to a third-party.

Citibank, N.A. Secured Loan. Our
subsidiary GMP has a secured loan with Citibank, N.A. under a loan agreement dated September 19, 2008 and amended on August 27, 2012 in an outstanding principal amount of S/.44.1 million (US$13.1 million) as of December 31,
2016.This loan accrues interest at an annual rate of three month LIBOR plus: (i) 1.70% if, at the installment payment date, the exchange rate between the sol and U.S. dollar remains between S/.2.60 to S/.2.75 per US$1.00 or
(ii) 1.95%, if otherwise. The loan matures in August 2020. The proceeds of the loan were used by our subsidiary GMP to finance the construction, equipment and operation of the Gas Pariñas plant in Talara. The agreement is secured by certain
land, equipment and accounts receivable of GMP. The agreement contains certain customary covenants, including restrictions on the ability of GMP to pay dividends if it is in default under the loan and the obligation by GMP to maintain the following
financial covenants during the term of the agreement: (a) Leverage Ratio (as defined therein) shall not be greater than 1.50; (b) DebtService Coverage Ratio (as defined therein) shall not be less than 1.20; (c) Liquidity Ratio
(as defined therein) shall not be less than 1.10; and (d) Debt Coverage Ratio (as defined therein) shall not be greater than 2.20.

Norvial Corporate Bonds.In July 2015, Norvial established its first
corporate bond program on the Lima Stock Exchange, for a total amount of S/.365 million (US$106.9 million). The first tranche under this program was issued for an amount of S/.80 million, due 2020 with an annual interest rate of 6.75%. The
second tranche was issued for an amount of S/.285 million, due 2027 with an annual interest rate of 8.375%, structured in three disbursements. In July 2015 we received the first disbursement for S/.105 million, in January 2016 we received
the second disbursement for S/.100 million and in July 2016 we received the third disbursement of S/.80 million. These bonds are secured by: (i) certain cash flows; (ii) a mortgage on the Norvial concession; (iii) a lien
over Norvial shares; (iv) the assignment of Norvials rights over a performance bond provided by GMP; and (v) any additional guarantees granted in favor of other secured creditors. The proceeds of these bonds were used to pay
S/.85 million of debt outstanding under a short-term loan agreement with Banco de Crédito del Perú (BCP) for a total S/.150 million, and the rest was used to finance the construction of the second stage of Ancon  Huacho
Pativilca highway and the value added tax linked to the implementation of the project expenses. As of December 31, 2016, Norvial had S/.363 million (US$108.1 million) outstanding under these bonds.

Senior Secured Notes.On February 2015, GyM Ferrovías issued a total of S/.629,000,000 (US$184.3 million) Series A
Senior Secured VAC-Indexed Notes due 2039, with an annual interest rate of 4.75% plus adjustments for inflation. The bonds are secured by (i) a mortgage on the Lima Metro concession, (ii) a lien on
GyM Ferrovías shares, (iii) certain collection rights, (iv) certain cash flows and (v) liens on certain accounts.The proceeds from the issuance were used to repay a short term loan provide by Banco de
Crédito del Perú-BCP for S/.400 million, funding of the reserve accounts, payment of the issuance expenses, and for the partial repayment of a subordinated loan provided by certain
shareholders of GyM Ferrovias to GyM Ferrovías. According to the indenture, in order to make any payment of a subordinated loan or distribute any dividends, our Debt Service Coverage Ratio (as defined therein) should be at least 1.2x.
Under the indenture GyM Ferrovías has fund the debt service reserve account on a quarterly basis with the equivalent of the amounts due in the next two succeeding interest payment dates. Moreover, the operation and maintenance reserve account
must be funded annually with an amount equal to twenty-five percent (25%) of operation and maintenance costs of the corresponding current annual budget. As of December 31, 2016, GyM Ferrovías had S/.604 million (US$179.5 million)
outstanding under these notes.

Financing of the Expansion Project of the Lima Metro Concession. On August 23, 2017, GyM
Ferrovias entered into a US$396 million financing structure with Mizuho Bank, Ltd and Sumitomo Mitsui Banking Corporation. The particular structure for the expansion project of the Lima Metro involves the securitization of irrevocable and
unconditional payment obligations of the Government of Peru (CPAOs), which have been sold by GyM Ferrovias to a borrower under a long-term loan facility. The expansion project includes the improvement of civil works and the purchase of additional
rolling stock, including trains and cars that will be designed, built, operated and maintained by GyM Ferrovías, as concessionaire under the Lima Metro concession. The financing is structured as a long-term loan facility and a working capital
facility.

As of the date of this annual report, GyM Ferrovias is in continuing default under the financing of the expansion project due
to the non-delivery of our audited consolidated financial statements for the 2016 fiscal year, in our capacity as guarantor of the obligations of GyM Ferrovias under the agreement. We have initiated the
process of obtaining a waiver from lenders.

BCP Loan.In December 2015, our subsidiary GMP S.A. and Oiltanking Peru S.A.C.
subscribed in equal parts to a medium term loan credit agreement for up to US$100 million with Banco de Credito del Peru, comprised of (i) a medium term tranche for up to US$70 million (for additional investments) with an annual
interest rate of 6.04% and a term of five years, and (ii) a medium term tranche for up to US$30 million (for committed investments) with an annual interest rate of 6.32% and a term of eight years. The tranches of the loan mature in 2024
and 2027, respectively. The proceeds of this loan are to finance Terminales del Perus obligations in the operation contracts that it maintains with Petroperu in regards to the Central Terminal (corresponding to the Callao Port), and North
Terminals (corresponding to the Etén, Salaverry, Chimbote and Supe Ports).As of December 31, 2016, GMP S.A. had US$8.2 million (S/.27.6 million) outstanding under this loan.

Syndicated Loan. In December 2015 we entered into a medium term loan credit agreement for up to US$200 million (S/.672 million)
with Credit Suisse AG, Cayman Islands Branch, and Credit Suisse Securities (USA) LLC. The term of the loan is five years, with quarterly installments starting on the 18th month. The loan accrued interest at a rate of three months Libor plus 3.9% per
year. The proceeds were used to finance our equity participation in Gasoducto Sur Peruano (GSP), which was the concessionaire of the southern gas pipeline project. As of December 31, 2016, the principal amount outstanding under this
loan was US$150 million (S/.504 million) and, as of the date of this annual report, the principal amount outstanding under this loan is US$76.3 million (S/.256.5 million).

As a result of the termination of the GSP gas pipeline concession, in June 2017, we entered into an amendment to the credit agreement.
According to the terms of the amendment, our syndicated loan matures in December 2020, with required prepayments to be made with the proceeds of asset sales of 40% in the first year and an additional 30% in the second year of the amendment. The
syndicated loan continues to accrue interest at LIBOR plus 4.90% per year. In addition, we are prohibited from paying dividends until the loan is repaid in full. Also, we have provided additional security interests, so that the amended syndicated
loan will be secured by: (i) a first lien on our shares of GyM and Concar; (ii) a first lien on our shares of Almonte; (iii) a first lien on certain real estate properties in Surquillo; (iv) liens on certain related accounts;
(v) a second priority lien on our shares of CAM and CAM Servicios del Perú S.A.; and (vi) a first lien on cash flows from the sale of certain assets.

The amendment to the credit agreement contains certain covenants, including the obligation by us
to maintain the following financial ratios during the term of the agreement: (i) the Consolidated EBITDA to Consolidated Interest Expense Ratio (as defined therein) shall not be less than 3.5:1.0 commencing on April 1, 2018 and thereafter;
(ii) the Consolidated Leverage Ratio (as defined therein) shall not be greater than (a) 3.5:1.0 at any time during the period commencing on December 31, 2016 and ending on March 31, 2017; (b) 3.5:1.0 at any time during the period
commencing on April 1, 2017 and ending on June 30, 2017; (c) 3.0:1.0 at any time during the period commencing on July 1, 2017 and ending on September 30, 2017; and (d) 2.5:1.0 at any time thereafter; and (iii) the
Debt Service Coverage Ratio (as defined therein) as of the last day of any fiscal quarter of the borrower, falling on or after the first anniversary of the closing date, shall not be less than 1.5:1.0 commencing on April 1, 2018 and thereafter.
Furthermore, the agreement contains a covenant restricting the CAM Chile Leverage Ratio (as defined therein) from exceeding 2.5:1.0 at any time. The agreement also imposes limitations, in an event of default, on ours and our subsidiaries
ability to distribute dividends, including, among others, that we may only distribute cash dividends to our stockholders out of 40% of our net income available for distribution in accordance with IFRS, as reflected in our audited consolidated
financial statements for the fiscal year most recently ended.

As of the date of this annual report, and due to the accounting adjustments
in connection to the termination of the GSP concession, we are again under certain continuing defaults under the syndicated loan with respect to the financial ratios and the non-delivery of the companys
audited consolidated financial statements for the fiscal years 2016 and 2017 on time. We are in the process of requesting waivers from the lenders.

GSP Bridge Loan and New Term Loan.With the termination of the GSP gas pipeline concession, our proportional guarantee under the GSP
bridge loan became due. As of December 31, 2016, there was US$129 million (S/.433.4 million) of principal amount outstanding under our corporate guarantee. As of the date of this annual report the principal amount outstanding under the GSP
bridge loan has been entirely paid. On June 27, 2017 we entered into a new US$78.7 million (S/.264.8 million) term loan with Natixis, BBVA, SMBC and MUFJ, the proceeds of which were used to prepay GSP bridge loan. The new term loan matures
on 2020, with required prepayments to be made with the proceeds of asset sales of 40% in the first year and an additional 30% in the second year of the amendment. The agreement with respect to such term loan contains a covenant restricting the
Consolidated Leverage Ratio (as defined therein) from exceeding 3.5:1.0 at any time and the CAM Chile Leverage Ratio (as defined therein) from exceeding 2.5:1.0 at any time. The term loan accrues interest at LIBOR plus 4.50% per year, which will
increase to 5.00% during the second year and to 5.50% during the third year. In addition, we will be prohibited from paying dividends until the loan is repaid in full. Also, the term loan will be secured by: (i) a first lien on our rights to
receive the termination payment derived from the GSP termination (the VCN); (ii) a second priority lien on our shares of GyM and Concar; (iii) a second priority lien on our shares of Almonte; (iv) a second priority lien on
certain real estate properties in Surquillo; (v) a second priority lien on our shares of CAM; (vi) a second priority lien on our shares of CAM Servicios del Perú S.A.; and (vii) a first lien on cash flows from the sale of
certain assets. As of the date of this annual report, there is US$72.5 million outstanding on the GSP bridge loan.

As of the date of
this annual report, we are under certain continuing defaults under the term loan with respect to the financial ratios and the non-delivery of the audited consolidated financial statements of the company for
the 2016 and 2017 fiscal years on time. We are in the process of requesting waivers from the lenders.

GSP Performance Guarantee.Upon the termination of the GSP gas pipeline concession, our proportional repayment obligations under the GSP performance guarantee from Chubb Insurance Company became due. As of December 31, 2016, we had US$52.5 million (S/.176.4
million) in obligations outstanding and, as of the date of this annual report, we had US$15.6 million (S/.52.6 million) in obligations outstanding. We recorded this amount as other accounts payable in our financial statements as of
December 31, 2016. On March 31, 2017, we renegotiated the terms of our repayment obligations. The new terms required repayment by March 31, 2018 and were extended until June 30, 2018, with interest accruing at 6% per year. The
new terms also provide a security interest over our shares in CAM and over cash flows from the sale of certain assets.

Financial Stability
Framework Agreement

On July 31, 2017, we, and certain of our subsidiaries, GyM, CAM Peru S.A., Vial y VivesDSD and
Concesionaria Vía Expresa Sur S.A., entered into a Financial Stability Framework Agreement (together with certain complementary contracts, the Framework Agreement) with the following financial entities: Scotiabank Peru S.A.A.,

existing standby letters of credit issued at the request of GyM and us, as well as the request of CAM Peru S.A., Vial y Vives  DSD and Concesionaria Vía Expresa Sur S.A. In April of 2018, we repaid US$73.9 million of the facility

under the agreement at a fixed exchange rate of S/.3.5952 per euro beginning in March 2013 and up to S/.3.6412 per euro in January 2014.

In August 2012, our subsidiary GMP entered into two interest rate swaps with Citibank, N.A. to hedge its exposure to fluctuations in LIBOR
under its unsecured loan with Citibank, N.A. described above. These interest rate swaps establish a fixed annual rate of 5.05%, payable at each interest payment date under the loan.

In September 2012, our subsidiary Viva GyM entered into a forward foreign exchange agreement with Banco de Crédito del Peru to hedge

D. Trend Information

Our Main Market: Peru

The following sets
forth key macroeconomic trends in our markets, Peru, Chile and Colombia. For additional information on trends in our business, see Item 5.A. Operating and Financial Review and ProspectsOperating ResultsFactors Affecting our Results

Overview of the Peruvian Economy

Our results are substantially affected by economic conditions prevailing in Peru. The Peruvian economy has been one of the fastest growing
economies globally during the period from 2013 to 2017. According to the Peruvian Central Bank, Peruvian real GDP grew at an average rate of 3.5% during that period, one of the highest rates in South America. The economic expansion during
this period was a result of robust domestic demand, increase in investment, price stability, increase in foreign direct investment, and an improvement in public finances, among other factors.

Nominal GDP per capita has increased from S/.17,645 in 2013 to S/.22,046 in 2017, a 24.9% increase. Average annual inflation, measured by
the change in the CPI index, was 3.0% in the period from 2013 to 2017. On the other hand, Perus Sol, depreciated from an average of S/.2.70 per US$1.00 in 2013 to an average of S/.3.26 per US$1.00 in 2017, a depreciation of 21%. Perus
sovereign debt has been granted investment grade rating by S&P, Fitch and Moodys. At the end of 2017, Peruvian sovereign debt had one of the highest credit ratings in the South American region, rated BBB+ by S&P (August 2013) and Fitch
(October 2013) and A3 by Moodys (July 2014).

The following table sets forth the main economic indicators of the Peruvian economy
from 2013 to 2017:

Mining

Peru is a poly-metallic resources
producer and exports several metals including silver, copper, zinc, gold and lead, among others. Peru is also a major contributor to global metal reserves. According to the U.S. Geological Survey of 2018, Peru holds 17.5% of global silver reserves,
12.2% of global zinc reserves, 10.3% of global copper reserves and 4.3% of global gold reserves, as of January 2018. According to the Peruvian Central Bank, mining exports reached approximately US$27.2 billion and represented 60.5% of total
Peruvian exports in 2017.

Upcoming mining projects comprise estimated capital expenditures of approximately US$18.9 billion from
2015 to 2017, according to APOYO Consultoría. As of December 2017, the Peruvian Ministry of Energy and Mines estimates 46 mining projects at various stages of development involving an estimated investment of US$46.1 billion.

Power and Utilities

The power and utilities market in Peru has shown sustained growth with maximum electricity demand reaching 6,596 MW and growing at an average
annual rate of 4.5% during the five years from 2013 to 2017, according to the Economic Operations Committee of Perus National Interconnected System. The growth of the power and utilities market has led to the construction of power generation
facilities, as well as the expansion of the power transmission and distribution network.

According to the Economic Operation Committee of
the National Interconnected System (COES SINAC), Peru had an installed generation capacity of 11,970 MW as of December 2017. As of 2017, the Peruvian market was served by 54 generation companies. As of December 2017, the nations
power transmission network spanned approximately 28,537 kilometers, according to the COES SINAC. As of 2017, there were 13 electric distribution companies across Peru.

Oil and Gas

The oil and gas activity in
Peru has decreased with a sector nominal GDP average annual growth rate of (1.6)% during the five years from 2013 to 2017. Oil and gas activity includes the exploration and production, and transportation and commercialization of hydrocarbon products
and derivatives.

According to the Peruvian Ministry of Energy and Mines, during 2017, local production of hydrocarbons was approximately
16 MMbbl of Petroleum, 33 MMboe of liquefied natural gas (LNG) and 81 MMboe of natural gas. These levels decreased an average of 3.3% annually from 2013 to 2017. Peruvian gas production increased considerably since 2004, when the Camisea
project, the largest gas project in Peruvian history, began operations. The Peruvian Ministry of Energy and Mines reports that as of 2016 proven reserves of oil and gas amounted to 3,906 MMboe. These reserves have increased since 2009, due to
increased exploration activities, as evidenced in the chart below. The Peruvian governments reserves methodology may differ materially from the one mandated by the SEC.

A. Directors and Senior
Management

General

Our business
and affairs are managed by our board of directors in accordance with our by-laws, shareholder meeting rules of procedure, board of directors rules of procedure, internal rules of conduct and Peruvian Corporate
Law No. 26887 (Peruvian Corporate Law). Our bylaws provide for a board of directors of between five and nine members. Our shareholders may appoint an alternate director for each director to act on his or her behalf when absent from
meetings or unable to exercise his or her duties. Alternate directors have the same responsibilities, duties and powers of directors to the extent they are called to replace them.

Directors are elected at a shareholders meeting and hold office for three years. Directors may be elected to multiple terms. Our current
board of directors is composed of nine directors and no alternates. If a director resigns or otherwise becomes unable to continue with the duties, a majority of our directors may appoint one of the alternate directors, or in the absence of alternate
directors, any other person, to serve as director for the remaining term of the board. In the first board meeting held after the annual shareholders meeting where members of the board are elected, the board of directors must elect among its
members a chairman and a vice chairman if the shareholders meeting did not elect them.

The board of directors typically meets in
regularly scheduled quarterly meetings and when called by any director or our Chief Executive Officer. Resolutions must be adopted by a majority of the directors present at the meeting and the chairman is entitled to cast the deciding vote in the
event of a tie.

Duties and Liabilities of Directors

Pursuant to Article 177 of Peruvian Corporate Law, directors are jointly and severally liable to a corporation, shareholders and third parties
for any damages caused by abuse of power, fraud, willful misconduct or gross negligence. In addition, pursuant to Article 3 of Law No. 29720, as amended, directors of companies with common shares listed on the Lima Stock Exchange are liable to
the company and its shareholders for damages caused by resolutions which are favorable to their individual interest (or the interest of a related party) to the detriment of the companys interest if: (i) the listed company is a party to
the transaction; (ii) the controlling

##### Table of Contents

shareholder of the listed company controls the legal entity acting as counterparty; (iii) the transaction is not carried out on an arms length basis; and (iv) at least 10% of the
listed companys assets are involved in the transaction. A director cannot be found liable if he/she did not participate in the respective meeting or if the directors express disagreement is noted in the corresponding record.

Article 180 of the Peruvian Corporate Law requires a director with a conflicting interest on a specific matter to disclose such interest and
abstain from the deliberation and decision-making process with respect to such matter. A director who violates this requirement is liable for any damages caused to us and may be removed by a majority of the board of directors upon request of any
member of the board or by a majority vote of the shareholders.

Pursuant to Article 181 of Peruvian Corporate Law, shareholders are
entitled to protect the interest of a company through derivative law suits against directors in order to remedy or prevent a wrong to the corporation. In addition, pursuant to Article 4 of Law No. 29720, with respect to companies listed on the
Lima Stock Exchange, a shareholder holding shares which represent at least 10% of the paid capital may bring said action against the directors.

Executive Compensation Plan

We establish and pay executive compensation in compliance with applicable labor and tax regulations and corporate governance standards and in
accordance with market conditions.

We establish pay scales taking into consideration executives responsibilities, including the
degree of complexity of those responsibilities, power of decision-making and scope of supervision entrusted.

The fixed salary component
of compensation is established for each position based on a pay scale. Fixed salary includes family allowance and cost of living payments, if applicable. We evaluate executives at least once a year to develop action plans in furtherance of
continuously improving management performance.

The variable component of compensation is paid to executives and other employees for
meeting specific goals, and is related both to his or her performance and our financial results. Variable compensation is typically paid as an annual bonus.

In addition, labor regulation establishes a mandatory profit sharing provision of 5% of our total annual taxable income, to be distributed
among all employees, calculated based on a formula established by law that considers the days worked in the year and remuneration.

Our
executives also receive additional benefits, typically non-pecuniary. The benefits granted include: (i) a vehicle owned and maintained by the company, with the purpose of facilitating transportation of
executives in the performance of their functions; (ii) a fuel allowance to offset transportation costs in the performance of their functions; and (iii) an insurance policy, including work accident and high risk coverage.

In addition, we have established a plan for certain executives effective March 2013 that awards cash bonuses for the exclusive use of
purchasing shares of our company or of our subsidiaries. The executive must agree to hold the shares for a specific period. If the executive is no longer employed with the company during such period, we are entitled to repurchase the shares at the
original purchase price. This benefit is awarded at the discretion and subject to the approval of the Human Resource Management Committee of our board of directors.

D. Employees

We have developed an extensive and talented team, including more than 3,800 engineers, which gives us the capability and scale to undertake
large and complex projects. We also have access to a network of approximately 156,000 manual laborers throughout Peru that can supplement our workforce when required by our projects. Moreover, we have the flexibility to engage our own workers on
projects outside Peru, avoiding the need to seek new employees in other countries.

As of December 31, 2016, we had a total of 32,513
full-time employees, including approximately 8,493 manual laborers, a number that fluctuates depending on our project backlog. At such date, we also worked with 4,434 employees of subcontractors. Occasionally, we employ subcontractors for particular
aspects of our projects, such as carpenters, specialists in elevator installation and specialists in glassworks. We are not dependent upon any particular subcontractor or group of subcontractors. As of December 31, 2016, 40.4% of our employees
worked outside Peru. The following table sets forth a breakdown of our employees by category as of December 31, 2016.

##### Table of Contents

Our talent development system has allowed us to develop a team of professionals who are able to
design and implement sophisticated projects. Our talent development system is based on three main pillars: (i) specialized training for all levels, including senior management; (ii) mentoring; and (iii) feedback from managers to
employees.

We have implemented programs to attract young and qualified candidates. Our Trainee, Academic Excellence and Young Engineers
programs offer various types of internships and training opportunities to engineering students and recent graduates, rewarding the most successful candidates with the opportunity to work as full-time, permanent employees. Our focus is not only to
attract talented people but also to retain them. Therefore, during the last eight years we have worked together with Great Place to Work ®, a human resources consulting, research and training
firm, to measure our employees satisfaction with the working environment. According to studies carried out by Great Place to Work ® during 2016, 74% of our engineers, technical
specialists and other professional employees confirmed that we are a great place to work. Moreover, our subsidiaries Viva GyM, Stracon GyM, GMP and GMD were recognized by Great Place to Work
® as being among the 45 best companies to work for in Peru. In April 2016, our subsidiary Viva GyM was recognized by Great Place to Work among the best 50 companies in Latin America.

Through our Graña y Montero Academy, we offer continuing education opportunities through a wide selection of courses and training
programs targeted at each level. We believe the knowledge that our employees gain through these programs is reflected in the way they work and relate to our clients, adding value in every step. During 2016, we invested more than US$6.5 million
in continuing education, reaching approximately 380,617 hours of capacitation activities for our employees.

We place significant emphasis
on instilling our core corporate values of quality, professionalism, reliability and efficiency on our employees, and on promoting safety, environmental sustainability and social responsibility throughout the entire organization. Our Code of Conduct
and Charter of Ethics regulate the conduct of our employees while promoting the foregoing values. In addition, our employees participate in ethics seminars on a periodic basis.

Substantially all of our manual laborers and some of our other employees are members of labor unions. Our practice is generally to extend the
benefits we offer our unionized employees to non-unionized employees. We consider our current relationship with unions to be positive.

In our E&C segment, collective bargaining agreements are negotiated at two levels: (i) on an annual basis between the National
Federation of Civil Construction and the Peruvian Chamber of Construction, without our direct involvement; and (ii) on a per project basis directly between the unions and our project committees, in accordance with such annual agreement. In
addition, some of our personnel in our gas processing plant belongs to the labor union Unicode Workers Union GMP S.A. We currently have collective bargaining agreements with some of our gas processing plant workers. In the case of our operation and
maintenance of infrastructure assets business, some of our personnel in CAM Perú are subject to a collective bargaining agreement. These collective bargaining agreements are negotiated on an annual basis.

Safety

We safeguard the health
and safety of our employees and of all the persons present in our operations and services. To that end, we provide safe work conditions, we manage risks in a timely manner and we promote a culture of prevention, starting from the leadership and
commitment of our senior management.

In 2016, our company reached a total of 86,303,933 hours worked. During this period, we reported an
accident frequency index (FI) of 0.40 accidents for every 200,000 hours worked, thus remaining at a level similar to 2015 (0.39) and confirming the positive trend over the last three years.

Our occupational health and safety management system in our subsidiaries GyM, GMI, Stracon GyM, Morelco, GMP, CAM, GMD Adexus and Concar
(February 2017) are certified by OHSAS 18001. We believe a safe job site contributes to our reputation and ability to gain new business while enhancing employee morale and reducing costs and exposure to liability.

Under our framework, we provided over 100 thousand hours of training in risk prevention for managers and directors, 794 thousand
hours of training for employees and nearly 200 thousand hours of training for subcontractors. Additionally, to improve the leadership and commitment of our chain of command, these training sessions were complemented with periodic managers
visits to projects, the establishment of annual safety goals based on the type of activity, the generation of opportunities to share lessons learned, and the monitoring of safety panels by our board of directors.

B. Related Party Transactions

Peruvian Law Concerning Related Party Transactions

Peruvian law sets forth certain restrictions and limitations on transactions with certain related parties.

For instance, from a tax standpoint, the value of those transactions must be equal to the fair market value assessed under transfer pricing
rules, i.e., the value agreed to by non-related parties under the same or similar circumstances. Similarly, companies with securities registered in the Peruvian Public Registry of Securities (Registro
Público del Mercado de Valores), such as us, are required to comply with the following rules:



| |  |  | The directors and managers of the company cannot, without the prior authorization of the board of directors, (i) receive in the form of a loan money or assets of the company; or (ii) use, for their own benefit
or for the benefit of related parties, assets, services or credits of the company.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The execution of agreements that involve at least 5% of the assets of the company with persons or entities related to directors, managers or shareholders that own, directly or indirectly, 10% of the share capital,
requires the prior authorization of the board of directors (with no participation of the director involved in the transaction, if any).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The execution of agreements with a party controlled by the companys controlling shareholder requires the prior authorization of the board of directors and an evaluation of the terms of the transaction by an
external independent company (audit companies or other to be determined by the Peruvian Securities Commission).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The
external independent company that reviews the transaction should not be related to the parties involved therein, nor to directors, managers or shareholders that own at least 10% of the share capital of the company.

##### Table of Contents

As a general policy, we do not enter into transactions with directors and executive officers on
terms more favorable than what we would offer third parties. Any related party transaction we have entered into in the past has been in the ordinary course of business and on an arms length basis.

Article 30 of the internal regulations of our board of directors establishes a review procedure for identifying, approving and accounting for
related party transactions. Related party transactions are defined as any transaction entered into by and among our company and any shareholder that owns 1% or more of our companys or of our subsidiaries outstanding shares, directors,
senior executives and persons related to them. The Human Resource Management Committee is responsible for identifying, analyzing and approving each such transaction considering market conditions and potential benefits for us and the related party.
For ordinary course transactions carried out under market conditions, a general authorization for the operations of the business line is sufficient. For more information, see Item 6. Directors Senior Management and
EmployeesManagement.

Item 8. FINANCIAL INFORMATION

A. Consolidated Statements and Other Financial Information.

See Item 18 of this annual report on Form 20-F.

Legal and Administrative Proceedings

We
may, from time to time, become subject to various legal and administrative proceedings that are incidental to the ordinary conduct of our business. We are currently not party to any material legal or administrative proceedings, other than as
described below. As of December 31, 2016, we had recorded provisions amounting to S/.19.4 million in connection with legal and administrative proceedings. See note 30.e to our audited annual consolidated financial statements included in
this annual report.

Two securities class action complaints have been filed against us and certain of our current and former executive
officers in the Eastern District of New York during the first quarter of 2017. These complaints are consolidated into a single class action. We believe that we have meritorious defenses to the claims asserted, and we intend to defend ourselves
vigorously in these matters.

In July 2017, media reports alleged that certain construction companies in Peru, Brazil and Spain, including
our company, colluded as a construction club to receive public contracts. As a result of these reports, INDECOPI initiated an investigation regarding the anti-competitive activities of construction companies in Peru, including our
company. To date, there is no pending investigation of the company.

The Lava Jato commission of the Peruvian congress, which was
formed in November 2016 and tasked with investigating the alleged bribes of Brazilian companies to Peruvian public officials, has initiated congressional inquiries into the company and other construction companies in Peru. Certain of the
companys former board members and executive officers to have been required to give testimony at hearings before the commission, during which they have affirmed that the company was unaware of Odebrechts illicit activities.

Peruvian prosecutors have included José Graña Miró Quesada, the former Chairman of the company, in an investigation for
the crime of collusion, and Hernando Graña Acuña, a former board member of the company, for the crime of money laundering against the Peruvian government, each in connection with the IIRSA South project concession (tranches II and
III), in which we participated. Both were placed in preventive detention and have since been released. Gonzalo Ferraro Rey, the former Chief Infrastructure Officer of the company, has also been included in an investigation for the crime of money
laundering in connection with the same project.

Also in connection with investigations relating to the IIRSA South project concession
(tranches II and III), the Peruvian criminal prosecution has moved to charge the company and our construction subsidiary, GyM, as criminal defendants. Separately, the Ad Hoc Prosecutor has moved to directly include the company as a
civilly-responsible third party in connection with the same projects. A decision from the Peruvian judiciary on whether our company constitutes a civilly-responsible third party remains pending. In response, the Peruvian First National Preparatory
Investigation Court (Primer Juzgado de Investigación Preparatoria Nacional) notified us of its decision to formally include the company and GyM in its criminal investigation. We have appealed the courts decision to include the
company and GyM in the criminal investigation. We cannot assure you that our position in these proceedings will prevail.

##### Table of Contents

The Ad Hoc Prosecutor has also moved to directly include our subsidiary, GyM S.A., as a
civilly-responsible third party in the investigation relating to Tranches 1 and 2 of Line 1 of the Lima Metro. If our subsidiarys former or current officers are included and convicted, it may be required to pay civil damages to the Peruvian
government. A decision from the Peruvian judiciary regarding these matters remains pending, and we cannot assure you that our subsidiary will not be included or that our position would ultimately prevail.

A conviction of corruption or resolutions with government authorities may lead to criminal and civil fines as well as penalties, sanctions,
injunctions against future conduct, profit disgorgement, disqualifications from directly and indirectly engaging in certain types of business, the loss of business licenses or permits or other restrictions. Moreover, our involvement in corruption
investigations, and any findings of wrongdoing in such investigations, could further damage our reputation and have a material adverse impact on our ability to compete for business. Such investigations may also adversely affect our ability to pursue
strategic projects, and could potentially result in the termination or modification of certain existing contracts or relationships.

Dividends and
Dividend Policy

Dividend Policy

Our current dividend policy, adopted on March 26, 2013, is to distribute between 30% and 40% of the net profit from the preceding year, as
long as we hold such net profit on a consolidated basis, subject to contractual restrictions on our indebtedness. Holders of our common shares are entitled to receive dividends on a pro rata basis in accordance with their respective number of shares
held. Our dividend policy can be modified by a favorable vote of a majority of our shareholders and any changes become effective 30 days after approval.

Article 23 of our by-laws establishes that dividends distribution must be approved by our shareholders
during the annual shareholders meeting. The recommendation of our board of directors is required for the distribution of interim dividends, which must be subsequently ratified at a shareholders meeting.

Under Peruvian law, companies may distribute up to 100% of their profit (after payment of income tax) subject to a 10% legal reserve until the
legal reserve equals 20% of the total value of their capital stock. According to Article 40 of the Peruvian Corporate Law, in order to distribute dividends, profits must be determined in accordance with the individual financial statements of the
company.

Payment of Dividends

Dividends are paid to holders of our common shares as of a record date determined by us. In order to allow for the settlement of securities,
under the rules of the Peruvian Securities Commission, investors who purchase shares of a publicly-held company three business days prior to a dividend payment date do not have the right to receive such dividend payment. Dividends on issued and
outstanding common shares are distributed pro rata.

We may not make any dividend payments until all outstanding amounts under our
repayment obligations of the GSP performance guarantee have been repaid in full. In addition, we may not be able to make any dividend payments until all outstanding amounts under our syndicated loan and our corporate guarantee of the GSP bridge loan
have been repaid or discharged, as the case may be, in full. For more information, see Item 5.A. Operating and Financial Review and ProspectsOperating ResultsRecent Developments.

In addition, the indentures of the Senior Secured Notes issued by GyM Ferrovías and the Corporate Bonds issued by Norvial, contain,
respectively, certain customary covenants, including restrictions on our ability to pay dividends if we are in default under the agreement, and our medium term loan with Credit Suisse imposes, certain limitations in an event of default, on our
ability to distribute cash dividends. See Item 5.B. Operating and Financial Review and ProspectsLiquidity and Capital ResourcesIndebtedness.

Holders of common shares are not entitled to interest on accrued dividends. In addition, under Article 232 of the Peruvian Corporate Law, the
right to collect accrued dividends declared by a publicly-held company expires ten years from the original dividend payment date.

Decree No. 861, whose unified sole text was enacted by Supreme Decree No. 093-2002-EF, as amended (Ley del Mercado de Valores), and the resolutions issued
from time to time by the Peruvian Securities Commission. The purpose of the Securities Market Law is to promote the ordered development and transparency of the Peruvian securities markets, adequate protection for investors and the principles under
which the Peruvian securities market is intended to operate. The Securities Market Law contains the general rules for: (i) primary and secondary public offerings of securities; (ii) public offering of securities for acquisitions and sales;
(iii) local and international offerings, including simultaneous offerings; (iv) the Public Registry of Securities (Registro Público del Mercado de Valores); (v) reporting obligations of material information (hechos de

The Peruvian securities market
is regulated and supervised by the Peruvian Securities Commission (Superintendencia de Mercado de Valores), a governmental entity reporting to the Peruvian Ministry of Economy and Finance, with functional, administrative, economic, technical
and budgetary autonomy. The Peruvian Securities Commission is governed by the Superintendent, designated by the Peruvian Ministry of Economy and Finance, and by a five member board of directors convened by the Superintendent (who acts as Chairman of
the board). The other four members are appointed by the government under applicable legislation. The Peruvian Securities Commission issues from time to time resolutions which provide specific regulations or may impose sanctions in cases of
violations of the Securities Market Law or the resolutions issued by the Peruvian Securities Commission.

The Peruvian Securities
Commission, in order to achieve the Securities Market Law ́s purposes, has broad regulatory and supervisory powers, including (i) issuing general mandatory rules; (ii) supervision and oversight of compliance with applicable
legislation (including the power to order inspections and require the submission of information and documentation by entities that are under its jurisdiction and summon and interrogate any person that may contribute to its investigations); (iii)
imposing sanctions; (iv) managing the Peruvian securities market public registry; (v) verifying that public offerings meet filing requirements and that the securities subject to such offerings are duly recorded at the Peruvian securities
market public registry of securities; (vi) authorizing the incorporation and functioning of entities under its scope of supervision; and (vii) monitoring the content and accuracy of the financial and other information that is filed with
the Peruvian Securities Commission. The Peruvian Securities Commission is responsible for the enactment, interpretation and enforcement of rules and regulations issued under the Securities Market Law.

B.
Memorandum and Articles of Association

Set forth below is certain information relating to our share capital, including brief summaries
of certain material provisions of our bylaws, Peruvian Corporate Law and certain other laws and regulations of Peru, all as in effect as of the date hereof.

General

We are a publicly-held
corporation under Peruvian Corporate Law and registered with the Public Registry of Corporations in Lima. We are listed on the Lima Stock Exchange and the New York Stock Exchange.

Our by-laws provide that our principal corporate purposes are to engage in any and all activities
related to the construction and real estate businesses; to provide services related to the mining and hydrocarbons industries; to participate in all stages of development of public services and other infrastructure concessions; and to provide
management and corporate services to related and third parties. In addition, our company can realize investments and corporate transactions, including the acquisition, holding and transfer of securities of Peruvian and foreign companies.

Common Shares and ADSs

As of
December 31, 2016, we had 660,053,790 common shares outstanding. As of December 31, 2016, there were 2,000 owners of record of our common shares. Our common shares have a par value of S/.1.00 per share and have been fully subscribed and
are fully paid. Our common shares are registered in the Securities Public Registry of the Peruvian Securities Commission and are listed on the Lima Stock Exchange. Our ADSs are listed on the New York Stock Exchange.

Shareholders Liability

Under
Peruvian Corporate Law, holders of our common shares cannot vote on matters with respect to which they have a conflict of interest.

Under
Article 133 of the Peruvian Corporate Law, a shareholder must abstain from voting when faced with a conflict of interest. A resolution approved in disregard of this provision may be challenged under Article 139 of the Peruvian Corporate Law and the
shareholders that participated in the determination in breach of this provision, if their vote was key in attaining the required majority, may be held jointly liable.

##### Table of Contents

Redemption and Rights of Withdrawal

Under Article 200 of the Peruvian Corporate Law, holders of our common shares have redemption rights if: (i) we change our corporate
purpose; (ii) a change occurs in the place of organization to a foreign country; or (iii) any transformation, merger or significant spin-off occurs with respect to our company.

Preemptive and Accretion Rights

If we
increase our share capital, holders of our common shares have the right to subscribe to new common shares on a pro rata basis. Holders of common shares have preemptive rights in order to maintain their share interest in our share capital, unless the
capital increase (i) results from a conversion of debt to common shares, (ii) is approved by shareholders representing at least 40% of the subscribed voting shares provided that the capital increase does not favor, directly or indirectly,
certain shareholders to the detriment of others, or (iii) results from a corporate reorganization.

Shareholders who are in default
of any payments relating to subscribed but unpaid shares may not exercise their preemptive rights.

Voting Rights and Dividends

Holders of common shares are entitled to one vote per share, with the exception of the election of the board of directors, where each holder is
entitled to one vote per share per nominee. Each holders votes may be cast for a single nominee or distributed among the nominees at the holders discretion. To that effect, each of our common shares gives the holder the right to as many
votes as there are directors to be elected. Shareholders may pool votes in favor of one person or distribute them among various persons. Those candidates for the board who receive the most votes are elected directors. Holders of common shares may
attend and vote at shareholders meetings either in person or through a proxy.

Holders of common shares have the right to
participate in the distribution of dividends and shareholder equity resulting from liquidation. Our by-laws do not establish a maximum time limit for the payment of the dividends. However, according to Article
232 of the Peruvian Corporate Law, the right to collect past-due dividends in the case of companies that are publicly held companies, such as ours, expires ten years after the date on which the dividend
payment was due.

Our share capital may be increased by a decision of holders of common shares at a shareholders meeting. Capital
reductions may be voluntary or mandatory and must be approved by holders of common shares at a shareholders meeting. Capital reductions are mandatory when accumulated losses exceed 50% of the capital and to the extent such accumulated losses
are not offset by accumulated earnings and capital increases within the following fiscal year. Capital increases and reductions must be communicated to the Peruvian Securities Commission, the Lima Stock Exchange and SUNAT. Voluntary capital
reductions must also be published in the official gazette El Peruano and in a widely circulated newspaper in the city in which we are located.

Liquidation Rights

If we are liquidated,
our shareholders have the right to receive net assets resulting from the liquidation, after we comply with our obligation to pay all our creditors and after discounting any existing dividend liabilities. For this reason, we cannot assure that we
will be able to reimburse 100% of the book value of the common shares in case of bankruptcy or liquidation.

Ordinary and Extraordinary Meetings

Pursuant to Peruvian Corporate Law and our by-laws, the annual shareholders meeting must
be held during the three-month period after the end of each fiscal year. Additional shareholders meetings may be held during the year. Because we are a publicly-held corporation, we are subject to the special control of the Peruvian Securities
Commission, as provided in Article 253 of the Peruvian Corporate Law. If we do not hold the annual shareholders meeting during the three-month period after the end of each fiscal year or any other shareholders meeting required by our by-laws, a public notary or a competent judge shall call for such a meeting at the request of at least one shareholder of the common shares. Such meeting will take place within a reasonable period of time.

Pursuant to the Peruvian Corporate Law, other shareholders meetings are convened by the board of directors when deemed convenient by the
company or when it is requested by notarized letter by the holders of at least 5% of our common shares which voting rights are not suspended according to Peruvian Law. Pursuant to section 255 of the Peruvian Corporate Law, if the board expressly or
implicitly refuses to convene the shareholders meeting, a notary public or a competent judge will call for such meeting at the request of holders of at least 5% of our common shares. If a notary public or competent judge calls for a
shareholders meeting, the place, date and hour of the meeting, the agenda, the person who will preside the meeting and the notary public who will certify the resolutions of the meeting shall be indicated in the meeting notice. If the meeting
called is other than the annual shareholders meeting or a shareholders meeting required by the Peruvian Corporate Law or the by-laws, the agenda will contain those matters requested by the
shareholders who requested the meeting.

##### Table of Contents

Notices of Meetings

Since we are a publicly-held corporation, notice of shareholders meetings must be given by publication of a notice. The publication shall
occur at least 25 days prior to any shareholders meeting in the Peruvian Official Gazette, El Peruano, and in a widely circulated newspaper in the city in which we are located.

Quorum and Voting Requirements

According
to Article 33 of our by-laws and Article 257 of the Peruvian Corporate Law, shareholders meetings called for the purpose of considering a capital increase or decrease, the issuance of obligations, a
change in the by-laws, the sale in a single act of assets with an accounting value that exceeds 50% of our share capital, a merger, division, reorganization, transformation or dissolution, are subject to a
first, second and third quorum call, with each of the second and third quorum call to occur upon the failure of the preceding one. A quorum for the first call requires the presence of shareholders holding 50% of our total common shares. For the
second call, the presence of shareholders holding at least 25% of our total common shares is adequate, while for the third call there is no quorum requirement. These decisions require the approval of the majority of the common shares represented at
the shareholders meeting. Shareholders meetings convened to consider all other matters are subject to a first and second quorum call, with the second quorum call to occur upon the failure of the first quorum.

In accordance with Peruvian Corporate Law, only those holders of common shares whose names are registered in the companys stock ledger
not less than 10 days in advance of a meeting will be entitled to attend the shareholders meeting and to exercise their rights.

Limitations on
the Rights of Non-Residents or Foreign Shareholders

There are no limitations under our by-laws or Peruvian Corporate Law on the rights of non-residents or foreign shareholders to own securities or exercise voting rights with respect to our securities.

Disclosure of Shareholdings and Tender Offer Regulations

Disclosure of Shareholdings

There
are no provisions in our by-laws governing the ownership threshold above which share ownership must be disclosed.

However, according to Article 10 of CONASEV Resolution No 090-2005-EF-94.10, as amended, we must inform the Peruvian Securities Commission of the members of our economic group, comprised by our subsidiaries, and a list of our holders of common shares owning
more than a 5% share interest, as well as any change to such information.

Tender Offer Regulations

Peruvian securities regulations include mandatory takeover rules applicable to the acquisition of control of a publicly held company.

Subject to certain conditions, such regulations generally establish the obligation to launch a tender offer when a person or group of persons
acquires a significant interest in a publicly held company. According to the provisions set forth in CONASEV Resolution No.
009-2006-EF-94.10, a person acquires a significant interest in a listed company when such person (i) holds or has the power
to exercise directly or indirectly 25%, 50% or 60% of the voting rights in a listed company, or (ii) has the power to appoint or remove the majority of the board members or to amend its by-laws.

A tender offer may be launched prior or following an acquisition of the significant interest. The tender offer may be launched after the
significant interest is acquired if it is acquired (i) by means of an indirect transaction, defined as a relevant acquisition or interest increase through the acquisition of securities issued by a company that in turn holds share
capital of the target company; (ii) as a consequence of a public sale offer, or (iii) in no more than four transactions within a three-year period.

This mandatory procedure has the effect of alerting other shareholders and the market that an individual or financial group has acquired a
significant percentage of a companys voting shares, and gives other shareholders the opportunity to sell their shares at the price offered by the purchaser. The purchaser is required to launch a tender offer unless: (i) shareholders
representing 100% of the voting rights consent in writing, (ii) voting shares are acquired by a depositary in order to subsequently issue ADSs, or (iii) voting shares are acquired pursuant to the exercise of preemptive rights.

##### Table of Contents

Changes in Capital

Our by-laws do not establish special conditions to increase or reduce our share capital beyond what is
required under Peruvian Corporate Law.

Anti-Takeover Provisions

Our by-laws do not contain any provision that would have the effect of delaying, deferring or
preventing a change of control.

Board of Directors

For additional information regarding our board of directors, see Item 6. Directors, Senior Management and EmployeesDirectors and
Senior Management.

Form and Transfer

Common shares may be either physical share certificates in registered form or book-entry securities in the CAVALI S.A. ICLV book-entry
settlement system also in registered form. Furthermore, in the case of shares represented in book entries, the issuance of new shares which result from share splits or similar corporate events must also be represented in said form.

Furthermore, the Peruvian Corporate Law forbids publicly-held corporations, such as us, from including in their
by-laws stipulations limiting the transfer of their shares or restraining their trading in other ways. According to Article 18 of our by-laws, we cannot recognize a
shareholders agreement that contemplates limitations, restrictions or preferential rights on the transfer of shares, even if such an agreement is recorded in our stock ledger (matrícula de acciones) or in CAVALI. As of the date
of this annual report, no shareholders agreement is recorded in our stock ledger.

Arbitration

Our by-laws include an arbitration clause applicable to disputes arising from the interpretation of our
bylaws or Peruvian Corporate Law and their complementary provisions, among our company, our management and our shareholders. Any such arbitration will be subject to the regulations of the Arbitration Center of the Lima Chamber of Commerce. The
material terms of the arbitration clause are as follows:



| |  |  | any dispute, controversy or claim arising out of the performance and the interpretation of the by-laws and any action or remedy set forth in the Peruvian Corporate Law (Ley
General de Sociedades) among us, our current or former shareholders and/or our current or former management shall be settled by arbitration;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | any dispute, controversy or claim between us and a third party shall be also settled by arbitration, if agreed upon by all parties either expressly or tacitly;

| |  |  | arbitrations shall be conducted before a panel of three arbitrators;
| | - |  | --------------------------------------------------------------------

| |  |  | each party to a dispute shall appoint an arbitrator within 10 business days from receiving the notice of arbitration. The two selected arbitrators shall appoint the third arbitrator. If one of the parties fails to

C. Material Contracts

Syndicated Loan

In
December 2015 we entered into a medium term loan credit agreement for up to US$200 million (S/.672 million) with Credit Suisse AG, Cayman Islands Branch, and Credit Suisse Securities (USA) LLC. As a result of the termination of the GSP gas
pipeline concession, in June 2017, we entered into an amendment to the credit agreement. See Item 5. Operating and Financial Review and ProspectsLiquidity and Capital ResourcesIndebtedness. This agreement and the amendments
thereto have been filed as Exhibit 10.01 to this annual report.

Term Loan

As a result of the termination of the GSP gas pipeline concession, our proportional guarantee of the GSP bridge loan became due. On
June 27, 2017 we entered into a new US$78.7 million (S/.264.8 million) term loan with Natixis, BBVA, SMBC and MUFJ, the proceeds of which were used to prepay GSP bridge loan in full. See Item 5. Operating and Financial Review and
ProspectsLiquidity and Capital ResourcesIndebtedness. This agreement and an amendment thereto has been filed as Exhibit 10.02 to this annual report.

Financial Stability Framework Agreement

On July 31, 2017, we, and certain of our subsidiaries, GyM, CAM Peru S.A., Vial y VivesDSD and Concesionaria Vía Expresa Sur
S.A., entered into a Financial Stability Framework Agreement with the following financial entities: Scotiabank Peru S.A.A., Banco Internacional del Perú S.A.A., BBVA Banco Continenal, Banco de Crédito del Perú, Citibank del
Perú S.A. and Citibank N.A. In April 2018, we repaid US$73.9 million of the facility with the proceeds of the sale of Stracon. See Item 5. Operating and Financial Review and ProspectsLiquidity and Capital
ResourcesIndebtedness. This agreement has been filed as Exhibit 10.03 to this annual report.

GSP Concession and
Subordination Arrangements

In November 2015 we acquired a 20% interest in GSP, an entity which, on July 22, 2014, signed a
concession agreement with the government of Peru to build, operate and maintain the natural gas pipeline transportation system to satisfy the demand of certain cities in the southern region of Peru.

On January 24, 2017, the government of Peru terminated the contract, due to the impossibility of obtaining financial closing. In
accordance with the concession contract, the Peruvian government is required to carry out an auction process to sell GSPs assets and obtain a new concessionaire within one year of the contract termination, with the funds raised in the sale to
be used to pay the existing concessionaire for its investment in the project. Although the concession contract provides that payment must be made within one year of termination, the Peruvian Ministry of Energy and Mines has not made payment or, to
our knowledge, initiated the payment process. A summary of these provisions of the concession contract have been filed as Exhibit 10.04 to this annual report.

In 2016, in connection with efforts to restructure or sell Odebrechts participation in GSP, due to the corruption scandal surrounding
Odebrecht, Odebrecht contractually agreed to subordinate its claims under the concession to the other project partners, Enagás and ourselves. As a result, we and Enagas may be entitled to repayment of our percentage payment under the
concession contract prior to Odebrecht. However, on January 3, 2018, Odebrecht commenced arbitration proceedings against us, our subsidiary GyM and Enagás, seeking to invalidate the contractual subordination and certain voting and other
arrangements. These contractual arrangements have been filed as Exhibit 10.05 to this annual report.

For more information, see Item
5.A. Operating and Financial Review and ProspectsOperating ResultsRecent Developments.

D. Exchange
Controls

Since August 1990, there have been no exchange controls in Peru and all foreign exchange transactions are based on free
market exchange rates. Prior to August 1990, the Peruvian foreign market consisted of several alternative exchange rates. Additionally, during the 1990s, the Peruvian currency experienced a significant number of large devaluations, and Peru has
consequently adopted, and operated under, various exchange rate control practices and exchange rate policies, ranging from strict control over exchange rates to market determination of rates. Current Peruvian regulations on foreign investment allow
the foreign holders of equity shares of Peruvian companies to receive and repatriate 100 percent of the cash dividends distributed by such companies. Such investors are allowed to purchase foreign exchange at free market currency rates through
any member of the Peruvian banking system and transfer such foreign currency rates through any member of the Peruvian banking system and transfer such foreign currency outside Peru without restriction.

E. Taxation

Peruvian Tax Considerations

The following
is a general summary of material Peruvian tax matters under Peruvian law, as in effect on the date of this annual report, and describes the principal tax consequences of ownership of ADSs and common shares by
non-resident individuals or entities (Non-Peruvian Holders). Legislative, judicial or administrative changes or interpretations may, however, be forthcoming.
Any such changes or interpretations could affect the tax consequences to holders of ADSs and common shares and could alter or modify the conclusions set forth herein. This summary is not intended to be a comprehensive description of all of the tax
considerations that may be relevant to a decision to make an investment in the ADSs or common shares. In addition, it does not describe any tax consequences arising under the laws of any taxing jurisdiction other than Peru or applicable to an
individual or entity resident of Peru or to a person with a permanent establishment in Peru.

For purposes of Peruvian taxation:



| |  |  | individuals are residents of Peru, if they are Peruvian nationals who have established their place of residence in Peru or if they are foreign nationals with a permanence of more than 183 days in Peru in any 12-month period (in the latter case, the condition of Peruvian resident can only be acquired as of the 1st of January of the year following the fulfillment of residence conditions); and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | legal entities are residents of Peru if they are established or incorporated in Peru.
| | - |  | -------------------------------------------------------------------------------------

Cash Dividends
and Other Distributions

Cash dividends paid to Non-Peruvian Holders with respect to common
shares and amounts distributed with respect to ADSs are currently subject to Peruvian withholding income tax at a rate of 6.8%. For distributions occurring in 2017 and 2018, the applicable withholding rate will be 8%, whereas from 2019 the
applicable withholding rate will be 9.3%. Nevertheless, a 4.1% withholding tax rate will apply on distributions of retained profits and other concepts distributable as dividends reflected in the accounting statements of 2014. As a general rule, the
distribution of additional common shares representing profits, the distribution of shares which differ from the distribution of earnings or profits, as well as the distribution of preemptive rights with respect to common shares, which are carried
out as part of a pro rata distribution to all shareholders, will not be subject to Peruvian income tax or withholding taxes.

Capital Gains

Pursuant to Article 6 of the Peruvian income tax law, individuals and domiciled entities in Peru are subject to Peruvian income
tax on their worldwide income while non-domiciled entities are subject to Peruvian income tax only on their Peruvian source income.

Peruvian income tax law provides that income derived from the disposal of securities issued by Peruvian entities is considered Peruvian source
income and is therefore subject to income tax. Under current Peruvian income tax law, capital gains resulting from the disposal of American Depositary Receipts (ADRs) that represent shares issued by Peruvian entities are considered Peruvian source
income and therefore are subject to Peruvian income tax. Peruvian income tax law also provides that the taxable income resulting from the disposal of securities is equal to the difference between the sale price of the securities (which may not be
less than their fair market value) and their tax basis.

Notwithstanding the foregoing, capital gains resulting from the disposal of ADSs
or beneficial interest in ADSs that represent shares issued by a Peruvian entity are not considered Peruvian source income, and therefore are not subject to Peruvian income tax.

In the event ADSs are exchanged into common shares and such common shares are disposed of, capital gains resulting therefrom will be subject
to an income tax rate of either 5% or 30%, depending on where the transaction takes place. If the transaction is consummated in Peru, any capital gain will be subject to an income tax rate of 5%; and if the transaction is performed outside of Peru,
any capital gain will be subject to a 30% income tax rate.

Peruvian income tax law regulations have stated with respect to the transfer
of common shares, that transactions are deemed to be consummated in Peru if the common shares are transferred through the Lima Stock Exchange. From 2016 through December 31 of 2019, pursuant to the Law 30341, capital gains resulting from a
transfer of: (i) Common shares and investment shares, (ii) ADRs and Global Depositary Receipts (GDRs), (iii) Exchange Trade Funds (ETF) units that have underlying shares and / or securities



169

##### Table of Contents

representing debt, (iv) representative securities of debt, (v) Certificates of participation in mutual funds for investment in securities, (vi) Certificates of participation in
investment Funds in Rent of Real Property (FIRBI) and certificates of participation in Trustee of Securitization for Investment in Rent of Real Estate (FIBRA), and (vii) Negotiable invoices, in each case, through the Lima Stock Exchange will be
exempt from income tax, provided, however, that the following conditions are met:

(a) The transfer must be performed through a centralized trading
mechanism supervised by the Securities Market Superintendence;

(b) In any 12 months period, neither the seller or any person related to him must dispose
of more than 10% of the total number of common shares issued by the company through one or more simultaneous or successive operations; and

(c) The shares
must have a market presence, meaning that transactions in respect of those shares for a value exceeding four Tax Units (currently, S/.16,200) shall have occurred in at least 27 business days out of any 180 business day period including
the date of the transaction.

Any gain resulting from the conversion of ADSs into common shares or common shares into ADSs will not be
subject to taxation in Peru.

Likewise, it is important to notice that if after applying the exemption, the issuer delisted the securities
from the Registry of the Lima Stock Exchange, in whole or in part, in an act or progressively, within the next 12 months after the disposal is made, the exemption that is applied to the securities unlisted is lost.

Any Non-Peruvian Holder entities who acquires common shares will have the following tax basis:
(i) for common shares purchased by the transferor, the acquisition price paid for the shares; (ii) for common shares received by the transferor as a result of a share capital increase because of a capitalization of net profits, the par
value of such common shares; (iii) for other common shares received free of any payment, tax basis will be: (x) zero or the cost borne by the transferor, in the case of individuals and (y) the fair market value at the time of the
acquisition, in the case of entities; and (iv) for common shares of the same type acquired at different opportunities and at different values, the tax basis will be the weighted average cost. In cases where common shares are sold by Non-Peruvian Holders outside the Lima Stock Exchange, the tax basis must be certified by the Peruvian tax administration prior to the time payment is made to the transferor; otherwise it would not be possible to
deduct the tax basis and the 30% Peruvian income tax would apply to the total sale price. Under Peruvian income tax law, tax basis certification is granted by the Peruvian tax authorities within 30 business days after the filing of the corresponding
application. If the Peruvian tax authorities do not respond within the abovementioned period, the tax basis calculation will be deemed automatically approved.

In any transaction relating to Peruvian securities through the Lima Stock Exchange, CAVALI will act as withholding agent of the Peruvian
income tax. If the purchaser is a resident in Peru and the sale is not performed through the Lima Stock Exchange, the purchaser will act as withholding agent. In other cases, the transferor shall be obliged to self-assess the tax and pay it to the
Peruvian tax authorities within the first 12 business days of the month following the transfer.

Other Considerations

No Peruvian estate or gift taxes are imposed on the gratuitous transfer of ADSs or common shares. No stamp, transfer or similar tax applies to
any transfer of ADSs or common shares, except for commissions payable by seller and buyer to the Lima Stock Exchange (0.021% of value sold), fees payable to the Peruvian Securities Commission (0.0135% of value sold), brokers fees (about 0.05%
to 0.50% of value sold) and value added tax (at the rate of 18%) on commissions and fees. Any investor who sells its common shares on the Lima Stock Exchange will incur these fees and taxes upon purchase and sale of the common shares.

United States Federal Income Tax Considerations

The following summary describes certain United States federal income tax consequences to a United States Holder (as defined below) of the
purchase, ownership and disposition of our common shares and ADSs as of the date of this annual report. Except where noted, this summary deals only with common shares and ADSs held as capital assets (generally, property held for investment). As used
herein, the term United States Holder means a beneficial owner of common shares or ADSs that is for United States federal income tax purposes:



| |  |  | an individual citizen or resident of the United States;
| | - |  | -------------------------------------------------------



| |  |  | a corporation (or other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

This summary does not represent a detailed description of the United States federal income tax consequences applicable to you in light of your
particular circumstances and does not address the United States federal income tax consequences applicable to you if you are subject to special treatment under the United States federal income tax laws, including if you are:

The discussion below
is based upon the provisions of the Internal Revenue Code of 1986, as amended (the Code), and regulations, rulings and judicial decisions thereunder as of the date hereof, and such authorities may be replaced, revoked or modified so as
to result in United States federal income tax consequences different from those discussed below. There is currently no income tax treaty between the United States and Peru that would provide for United States federal income tax consequences
different than the consequences under the foregoing authorities. In addition, this summary is based, in part, upon representations made by the depositary to us and assumes that the deposit agreement, and all other related agreements, will be
performed in accordance with their terms.

If a partnership (or other entity or arrangement treated as a partnership for United States
federal income tax purposes) holds our common shares or ADSs, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding
our common shares or ADSs, you should consult your tax advisors.

This summary does not address the effects of the Medicare tax on net
investment income or other United States income tax consequences such as United States federal estate or gift tax consequences, and does not address the effects of any state, local or non-United States tax
laws. If you are considering the purchase, ownership or disposition of our common shares or ADSs, you should consult your own tax advisors concerning the United States federal income tax consequences to you in light of your particular situation as
well as any consequences arising under the laws of any other taxing jurisdiction.

ADSs

If you hold ADSs, for United States federal income tax purposes, you generally will be treated as the owner of the underlying common shares
that are represented by such ADSs. Accordingly, deposits or withdrawals of common shares for ADSs will not be subject to United States federal income tax.

##### Table of Contents

Taxation of Dividends

The gross amount of distributions, other than certain pro rata distributions of common shares, on the ADSs or common shares (including amounts
withheld to reflect Peruvian withholding taxes) will be taxable as dividends, to the extent paid out of our current or accumulated earnings and profits, as determined under United States federal income tax principles.

To the extent that the amount of any distribution (including amounts withheld to reflect Peruvian withholding taxes) exceeds our current and
accumulated earnings and profits for a taxable year, as determined under United States federal income tax principles, the distribution will first be treated as a tax-free return of capital, causing a reduction
in the adjusted basis of the ADSs or common shares, and the balance in excess of adjusted basis will be taxed as capital gain recognized on a sale or exchange. However, we do not expect to keep earnings and profits in accordance with United States
federal income tax principles. Therefore, you should expect that a distribution will generally be treated as a dividend. Such dividends (including any withheld taxes) will be includable in your gross income as ordinary income on the day actually or
constructively received by you, in the case of the common shares, or by the depositary, in the case of ADSs. Such dividends will not be eligible for the dividends received deduction allowed to corporations under the Code.

With respect to non-corporate United States Holders, certain dividends received from a qualified
foreign corporation may be subject to reduced rates of taxation. A non-United States corporation is treated as a qualified foreign corporation with respect to dividends received from that corporation on common
shares (or ADSs backed by such shares) that are readily tradable on an established securities market in the United States. United States Treasury Department guidance indicates that our ADSs, which are listed on the New York Stock Exchange, will be
considered readily tradable on an established securities market in the United States. Based on existing guidance, it is not entirely clear whether our common shares will be considered readily tradable on an established securities market in the
United States because only the ADSs, not the underlying common shares, are listed on a securities market in the United States. We believe that dividends we pay on our common shares that are represented by ADSs, but not our common shares that are not
so represented, will meet such conditions required for the reduced tax rates. There can be no assurance that our ADSs will be considered readily tradable on an established securities market in later years.
Non-corporate United States Holders that do not meet a minimum holding period requirement during which they are not protected from the risk of loss or that elect to treat the dividend income as
investment income pursuant to Section 163(d)(4) of the Code will not be eligible for the reduced rates of taxation regardless of our status as a qualified foreign corporation. In addition, the rate reduction will not apply to
dividends if the recipient of a dividend is obligated to make related payments with respect to positions in substantially similar or related property. This disallowance applies even if the minimum holding period has been met. You should consult your
own tax advisors regarding the application of these rules given your particular circumstances.

The amount of any dividend paid in soles
will equal the U.S. dollar value of the soles received, calculated by reference to the exchange rate in effect on the date the dividend is actually or constructively received by you, in the case of the common shares, or by the depositary, in the
case of ADSs, regardless of whether the soles are converted into U.S. dollars at that time. If the soles received as a dividend are converted into U.S. dollars on the date they are received, you generally will not be required to recognize foreign
currency gain or loss in respect of the dividend income. If the soles received as a dividend are not converted into U.S. dollars on the date of receipt, you will have a tax basis in the soles equal to their U.S. dollar value on the date of receipt.
Any gain or loss realized on a subsequent conversion or other disposition of the soles will be treated as United States source ordinary income or loss.

Subject to certain conditions and limitations, Peruvian withholding taxes on dividends may be treated as foreign taxes eligible for credit
against your United States federal income tax liability. For purposes of calculating the foreign tax credit, dividends paid on the ADSs or common shares will be treated as foreign source income and will generally constitute passive category income.
However, in certain circumstances, if you have held the ADSs or common shares for less than a specified minimum period during which you are not protected from risk of loss, or are obligated to make payments related to the dividends, you will not be
allowed a foreign tax credit for any Peruvian withholding taxes imposed on dividends paid on the ADSs or common shares. If you do not elect to claim a United States foreign tax credit, you may instead claim a deduction for Peruvian income tax
withheld, but only for a taxable year in which you elect to do so with respect to all foreign income taxes paid or accrued in such taxable year. The rules governing the foreign tax credit are complex. You are urged to consult your tax advisors
regarding the availability of the foreign tax credit under your particular circumstances.

Taxation of Capital Gains

For United States federal income tax purposes, you will recognize taxable gain or loss on any sale or exchange of ADSs or common shares in an
amount equal to the difference between the amount realized for the ADSs or common shares and your tax basis in the ADSs or common shares, in each case as determined in U.S. dollars. Such gain or loss will generally be capital gain or loss. Capital
gains of non-corporate United States Holders derived with respect to capital assets held for more than one year are eligible for reduced rates of taxation. The deductibility of capital losses is subject to
limitations.



172

##### Table of Contents

If a Peruvian income tax is withheld on the sale or other disposition of our ADSs or common
shares, your amount realized will include the gross amount of the proceeds of that sale or other disposition before deduction of the Peruvian income tax. See Peruvian Tax ConsiderationsCapital Gains for a description of when
a sale or other disposition of our ADSs or common shares may be subject to taxation by Peru. Any gain or loss recognized by you will generally be treated as United States source gain or loss for foreign tax credit purposes. Consequently, in the case
of gain from the disposition of ADSs or common shares that is subject to Peruvian income tax, you may not be able to benefit from the foreign tax credit for that Peruvian income tax (i.e., because the gain from the disposition would be United States
source), unless you can apply the credit (subject to applicable limitations) against United States federal income tax payable on other income from foreign sources. Alternatively, you may take a deduction for the Peruvian income tax if you do not
take a credit for any foreign taxes paid or accrued during the taxable year. You are urged to consult your tax advisors regarding the tax consequences if Peruvian income tax is imposed on a disposition of ADSs or common shares, including the
availability of the foreign tax credit under your particular circumstances.

Passive Foreign Investment Company

We do not believe that we are, for United States federal income tax purposes, a passive foreign investment company (a PFIC), and we
expect to operate in such a manner so as not to become a PFIC. If, however, we are or become a PFIC, you could be subject to additional United States federal income taxes on gain recognized with respect to the ADSs or common shares and on certain
distributions, plus an interest charge on certain taxes treated as having been deferred under the PFIC rules. Non-corporate United States Holders will not be eligible for reduced rates of taxation on any
dividends received from us (as discussed above under Taxation of Dividends) if we are a PFIC in the taxable year in which such dividends are paid or in the preceding taxable year.

Information Reporting and Backup Withholding

In general, information reporting will apply to dividends in respect of our ADSs or common shares and the proceeds from the sale, exchange or
redemption of our ADSs or common shares that are paid to you within the United States (and in certain cases, outside the United States), unless you are an exempt recipient. Backup withholding may apply to such payments if you fail to provide a
taxpayer identification number or certification of other exempt status or fail to report in full dividend and interest income.

Any
amounts withheld under the backup withholding rules will be allowed as a refund or a credit against your United States federal income tax liability provided the required information is furnished to the Internal Revenue Service in a timely manner.

The above description is not intended to constitute a complete analysis of all tax consequences relating to the acquisition, ownership or disposition
of our ADSs or common shares. You should consult your own tax advisors concerning the overall tax consequences to you, including the consequences under laws other than United States federal income tax laws, of an investment in our ADSs or common
shares.

H. Documents on Display

We are subject to the informational requirements of the U.S. Securities Exchange Act of 1934, or the Exchange Act. Accordingly, we are required
to submit reports and other information to the SEC, including annual reports on Form 20-F and reports on Form 6-K. You may inspect and copy reports and other information
submitted to the SEC at the public reference facilities maintained by the SEC at 100 F Street, N.E., Washington, D.C. Copies of the materials may be obtained from the Public Reference Room of the SEC at 100 F Street, N.E., Washington, D.C. 20549 at
prescribed rates. The public may obtain information on the operation of the SECs Public Reference Room by calling the SEC in the United States at
1-800-SEC-0330. In addition, the SEC maintains an Internet website at http://www.sec.gov, from which you can
electronically access these materials.

As a foreign private issuer, we are required to file with the SEC annual reports on Form 20-F, but we are not subject to the same disclosure requirements as a domestic U.S. registrant under the Exchange Act. For example, we are not required to prepare and issue quarterly reports. However, we have
furnished, and intend to continue to furnish, our shareholders with quarterly reports containing unaudited financial data for the first three quarters of each fiscal year. In addition, as a foreign issuer, we are not subject to the proxy rules under
Section 14 of the Exchange Act and our officers and directors are subject to Section 16 of the Exchange Act relating to insider short-swing profit disclosure and recovery regime.

##### Table of Contents

We send the depositary a copy of all notices that we give relating to meetings of our
shareholders or to distributions to shareholders or the offering of rights and a copy of any other report or communication that we make generally available to our shareholders. The depositary makes all these notices, reports and communications that
it receives from us available for inspection by registered holders of ADSs at its office. The depositary mails copies of those notices, reports and communications to you if we ask the depositary to do so and furnish sufficient copies of materials
for that purpose.

We file financial statements and other periodic reports with the Peruvian Securities Commission in Peru. Issuers of
securities registered with the Peruvian Securities Commission are required to disclose material information relating to the issuer. Pursuant to the Securities Market Law and relevant regulations enacted thereunder, all material information in
connection with the issuer of registered securities, its activities or securities issued or secured by such issuer which may influence the liquidity or price of such securities must be disclosed. Accordingly, issuers must file with the Peruvian
Securities Commission mainly two types of information: (a) financial information, including unaudited interim financial statements on a quarterly basis (which are not required to be subject to limited review), and audited annual consolidated
financial statements on an annual basis, and (b) material information relating to the issuer and its activities that may significantly affect the price, offering or negotiation of the issued securities, and in general, all the information that
may be relevant for investors to be able to make investment decisions.

I. Subsidiary Information

See the notes 2.2 and 7 to our consolidated financial statements included in this annual report for a description of our subsidiaries.



|Item 11. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

We are exposed to a number
of market risks arising from our normal business activities, including the possibility that changes in currency exchange rates or interest rates will adversely affect future cash flows and profit or the value of our financial assets and liabilities.
From time to time, we enter into derivative transactions to hedge against foreign currencies and interest rate fluctuations. For further information regarding our market risk, see note 3 to our audited annual consolidated financial statements
included in this annual report.

Exchange Rate Risk

We are exposed to market risk associated with changes in foreign currency exchange rates. Our revenues and costs, and our assets and
liabilities, are denominated in soles, U.S. dollars, Chilean pesos and, to a lesser extent, other currencies. In 2016, 46%, 33% and 21% of our revenues were denominated in soles, U.S. dollars and other currencies (principally Chilean pesos),
respectively, while 55%, 22% and 23% of our cost of sales during the year were denominated in soles, U.S. dollars and other currencies. In addition, as of December 31, 2016, 46.7%, 45.6% and 7.6% of our total debt was denominated in soles, U.S.
dollars and other currencies, respectively. If, at December 31, 2016, the sol had strengthened/weakened by 2% against the U.S. dollar, with all other variables remaining constant, or pre-tax profit for
the year would have increased/decreased by S/.0.2 million. This sensitivity analysis does not take into account our payable to Chubb Insurance Company relating to our reimbursement obligations under the GSP performance guarantee.

Interest Rate Risk

We may from
time to time incur variable interest rate indebtedness, and accordingly our financial expenses are affected by changes in interest rates. Based upon our indebtedness at December 31, 2016, and taking into account our interest rate derivative
instruments, a change in interest rates of five percent (or 500 basis points) would impact our net profit by S/.80.3 million annually. This sensitivity analysis does not take into account our payable to Chubb Insurance Company relating to our
reimbursement obligations under the GSP performance guarantee.

Commodity Price Risk

We are exposed to market risk associated with changes in commodity prices, primarily for oil, steel and cement, which in aggregate represented
a majority of our total input cost in 2016. We do not have long-term contracts for the supply of these key inputs. Based upon our consumption of these inputs during 2016, a 10% increase/decrease in the prices of each of oil, steel and cement would
have increased/decreased our costs of sales by S/.59.1 million, S/.15.2 million and S/.3.0 million, respectively. However, based on our production of oil during 2016, a 10% increase/decrease in the price of oil would have
increased/decreased our revenues by S/.66.0 million.

such deposit to pay such charge.

The following additional charges shall be incurred by the ADR holders, by any party depositing or

securities or a distribution of ADSs), whichever is applicable:



| |  |  | a fee of US$1.50 per ADR or ADRs for transfers of certificated or direct registration ADRs;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | a fee of US$0.05 or less per ADS for any cash distribution made pursuant to the deposit agreement;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | a fee of US$0.05 or less per ADS per calendar year (or portion thereof) for services performed by the depositary in administering the ADRs (which fee may be charged on a periodic basis during each calendar year and
shall be assessed against holders of ADRs as of the record date or record dates set by the depositary during each calendar year and shall be payable in the manner described in the next succeeding provision);
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a fee for the reimbursement of such fees, charges and expenses as are incurred by the depositary and/or any of the depositarys agents (including, without limitation, the custodian and expenses incurred on behalf
of holders in connection with compliance with foreign exchange control regulations or any law or regulation relating to foreign investment) in connection with the servicing of the common shares or other deposited securities, the sale of securities,
the delivery of deposited securities or otherwise in connection with the depositarys or the custodians compliance with applicable law, rule or regulation (which charge shall be assessed on a proportionate basis against holders as of the
record date or dates set by the depositary and shall be payable at the sole discretion of the depositary by billing such holders or by deducting such charge from one or more cash dividends or other cash distributions);

| |  |  | expenses of the depositary in connection with the conversion of foreign currency into U.S. dollars.
| | - |  | ---------------------------------------------------------------------------------------------------

We will pay all other charges and expenses of the depositary and any agent of the depositary (except the custodian) pursuant to agreements
from time to time between us and the depositary. The charges described above may be amended from time to time by agreement between us and the depositary.

Our depositary has agreed to reimburse us for certain expenses we incur that are related to establishment and maintenance of the ADR program,
including investor relations expenses and exchange application and listing fees. The amounts of reimbursements available to us are not based upon the amounts of fees the depositary collects from investors. The depositary collects its fees for
issuance and cancellation of ADSs directly from investors depositing common shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting on their behalf. The depositary collects fees for making distributions to investors
by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deduction from cash distributions, or by directly billing
investors, or by charging the book-entry system accounts of participants acting for them. The depositary will generally set off the amounts owing from distributions made to holders of ADSs. If, however, no distribution exists and payment owing is
not timely received by the depositary, the depositary may refuse to provide any further services to holders that have not paid those fees and expenses owing until such fees and expenses have been paid. At the discretion of the depositary, all fees
and charges owing under the deposit agreement are due in advance and/or when declared owing by the depositary.

During 2016, the
depositary reimbursed us for expenses in an aggregate amount of US$89,950.06 (S/.302,232.20).

Financing
of the Expansion Project of the Lima Metro Concession

On August 23, 2017, GyM Ferrovias entered into a US$396 million
financing structure with Mizuho Bank, Ltd and Sumitomo Mitsui Banking Corporation. The particular structure for the expansion project of the Lima Metro involves the securitization of irrevocable and unconditional payment obligations of the
Government of Peru (CPAOs), which have been sold by GyM Ferrovias to a borrower under a long-term loan facility. The expansion project includes the improvement of civil works and the purchase of additional rolling stock, including trains and cars
that will be designed, built, operated and maintained by GyM Ferrovías, as concessionaire under the Lima Metro concession. The financing is structured as a long-term loan facility and a working capital facility.

As of the date of this annual report, GyM Ferrovias is in continuing default under the financing of the expansion project due to the non-delivery of our audited consolidated financial statements for the 2016 fiscal year, in our capacity as guarantor of the obligations of GyM Ferrovias under the agreement. The financing required that we provide
the financial statements no later than April 4, 2018. Also, the financing requires that we deliver our audited consolidated financial statements for the 2017 fiscal year by May 15, 2018. We will not be able to deliver those financial
statements on time. We have initiated the process of requesting a waiver from the lenders.

Syndicated Loan

Due to the termination of the GSP gas pipeline concession on January 24, 2017, we were in breach of our covenants under our syndicated
loan as of December 31, 2016, as the effects on our financial condition and results of operations of the concession termination were taken into account for the purposes of calculating compliance with our financial covenants for 2016. As of
December 31, 2016, (a) our Consolidated EBITDA to Consolidated Interest Expense (as defined therein) was 3.33x rather than at least 3.5x as required under the syndicated loan, (b) our Consolidated Leverage Ratio (as defined therein) was
5.75x rather than no more than 3.5x as required under the syndicated loan, and (c) our Debt Service Coverage Ratio (as defined therein) was 3.83x rather than at least 1.5x as required under the syndicated loan. Additionally, upon the
termination of the GSP gas pipeline concession on January 24, 2017, we were required to prepay our syndicated loan. We amended the terms of our syndicated loan, including certain financial covenants and certain prepayment requirements.

As of the date of this annual report, and due to the accounting adjustments in connection to the termination of the GSP gas pipeline
concession, we are again under certain continuing defaults under the syndicated loan with respect to certain financial ratios and the non-delivery of our audited consolidated financial statements for the 2016
and 2017 fiscal years. The syndicated loan required that we provide the financial statements for the 2016 and 2017 fiscal years no later than April 30, 2018. As of March 2018, our Consolidated Leverage Ratio (as defined therein) was 2.62,
rather than no more than 2.50 as required under the syndicated loan. We are in the process of requesting waivers from the lenders.

GSP Bridge Loan and New Term Loan.

With the termination of the GSP gas pipeline concession, our proportional guarantee under the GSP bridge loan became due. As of
December 31, 2016, there was US$129 million (S/.433.4 million) of principal amount outstanding under our corporate guarantee. As of the date of this annual report the principal amount outstanding under the GSP bridge loan has been entirely
paid. On June 27, 2017 we entered into a new US$78.7 million (S/.264.8 million) term loan with Natixis, BBVA, SMBC and MUFJ, the proceeds of which were used to prepay GSP bridge loan.

As of the date of this annual report, we are under certain continuing defaults under the term loan with respect to certain financial ratios
and the non-delivery of our audited consolidated financial statements for the 2016 and 2017 fiscal years. The term loan required that we provide the financial statements for the 2016 and 2017 fiscal years no
later than April 30, 2018. As of the date hereof, our Consolidated Leverage Ratio (as defined therein) was 2.62, rather than no more than 2.50 as required under the syndicated loan. We are in the process of requesting waivers from the lenders.

Financial Stability Framework Agreement

As of the date of this annual report, we are under continuing default due to the non-delivery of our
audited consolidated financial statements and those of our subsidiary, GyM, for the 2016 and 2017 fiscal years. The loan required that we provide such financial statements no later than April 30, 2018. We are in the process of requesting
waivers from the lenders.

Use of Proceeds

On July 29, 2013,
we completed our initial public offering in the United States by issuing 20,353,920 ADSs, representing 101,769,600 common shares (including partial exercise of the underwriters over-allotment option on August 23, 2013, for cash
consideration of US$21.13 per ADS. We received approximately US$411.3 million in net proceeds from our initial public offering. We have used these net proceeds for capital investments, acquisitions and other general corporate purposes,
consistent with our disclosure in the registration statement relating to the initial public offering.



|Item 15. | CONTROLS AND PROCEDURES
|-------- | -----------------------

A. Disclosure Controls and Procedures

Management, with the participation of the companys Chief Executive Officer and Chief Financial Officer, performed an evaluation of the
effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Our disclosure controls and procedures are
designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms, and that such
information is accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed
and operated, can provide only reasonable assurance of achieving the desired control objective. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2016, our disclosure controls
and procedures were not effective as a result of the material weaknesses in internal control over financial reporting described below.

B. Managements Annual Report on Internal Control Over Financial Reporting

Management is responsible for establishing and
maintaining adequate internal control over financial reporting for our company as such term is defined by Exchange Act rules 13(a)-15(f) and 15(d)-15(f). In order to
evaluate the effectiveness of internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act of 2002 (the Sarbanes-Oxley Act), management has conducted an assessment, including testing, using the
criteria in Internal Control-Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Our companys system of internal control over financial reporting is designed to provide reasonable
assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of its



177

##### Table of Contents

inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the
risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our assessment of the effectiveness of our internal control over financial reporting as of December 31, 2016, we have identified
certain material weaknesses. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim
financial statements will not be prevented or detected on a timely basis. The material weaknesses identified are described below:

Control
Environment

The control environment, which is the responsibility of senior management, helps set the tone of the organization,
influences the control consciousness of its officers and employees, and is an important component affecting how the organization performs risk management, financial analysis, accounting and financial reporting. A proper organizational tone can be
promoted through a variety of means, such as policies and codes of ethics, a commitment to hiring competent employees, the manner and content of oral and written communications, and structures that promote and reward openness, strong internal
controls, effective governance, risk management, compliance and ethical behavior.

As of December 31, 2016, we did not maintain an
effective control environment primarily attributable to the following identified material weaknesses:



| |  |  | Our assessment found that an inconsistent and ineffective tone at the top was present, under the then-existing senior management, that was not effective to ensure adherence to IFRS and our accounting policies and
procedures. This resulted in an environment which in some instances may have led to incorrect accounting decisions and the failure to disclose information that may be necessary for an effective review of transactions and accounting entries to the
appropriate finance and accounting personnel, our Board, our Audit and Process Committee, and/or independent registered public accounting firm. In addition, we identified an inadequate oversight by the Audit Committee regarding the role of the
Internal Audit Department. The control environment was not always sufficient to ensure that adequate entreprise risk management (including fraud risk) and monitoring mechanisms were in place to secure that our internal control over financial
reporting operated effectively, including that the relevant risk/control activities were carried out properly and that corrective actions were taken on a priority basis and in timely manner.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We did not have sufficient personnel with an appropriate level of knowledge, experience and training in the application of IFRS and with requirements of internal control over financial reporting commensurate with the
complexity of our financial reporting requirements.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These material weaknesses in the risk and control environment contributed to the
following additional material weaknesses, including the material weaknesses in risk assessment, information and communication, and monitoring and evidential matter.

Risk Assessment

We identified
deficiencies in the controls to address the risks of a material misstatement. Specifically, changes to existing controls or the implementation of new controls were not sufficient to respond to changes to the risks of material misstatements to
financial reporting, due in part to acquisitions, dispositions and other changes to the business. These deficiencies contributed to the following additional material weaknesses:



| |  |  | Accounting closing process with respect to the review of the consolidated and separate financial statements: we identified deficiencies in the controls over certain business processes including our period-end financial reporting process, including the identification and execution of controls over financial statement analyses required to assess the appropriateness of certain account balances at period-end and the control over the completeness and accuracy of interim and annual financial statement presentation and disclosure.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Controls over the review, approval and documentation related to journal entries: we identified deficiencies in design and operational effectiveness of the controls over the review, approval and documentation related to
journal entries. Specifically, effective controls were not in place to verify and properly approve that journal entries were prepared with sufficient supporting documentation, reports and spreadsheets used to support the journal entries were
complete and accurate.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | Deficiencies in the design and operational effectiveness of controls over segregation of duties: we identified deficiencies in design and operational effectiveness of the controls over segregation of duties to ensure
that conflicted individuals were not involved in activities related to their conflicts or that such activities were monitored by appropriate individuals using complete and accurate information.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Deficiencies in the design of controls over the timely accounting for signed contracts: we identified deficiencies in the design of the controls, including entity-level controls and process-level controls to prevent or
detect material inaccuracies, related to the accounting for the contracts signed with certain companies with which we are associated (Consorcio Constructor Ductos del Sur), one of the companys significant joint arrangements. Specifically, we
identified deficiencies related to the accounting assessment of joint arrangement contracts and the assessment of the completeness of contracts, which is relevant to verifying all contracts and addenda are accounted for, including any changes in the
percentage-of-interests held in certain entities. We noted that certain entities (i.e. consortia) were accounted for using an accounting basis that was not consistent
with the nature/type of the joint arrangement contracts. Nevertheless, there were no significant impacts in our consolidated financial statements because clarifying addendums were signed by the parties.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Deficiencies in the design and operational effectiveness of controls established with respect to the recognition of revenue: we identified deficiencies in design and operational effectiveness of the controls related to
the accounting for revenue and accounts receivable, including construction contract revenues and contingent revenues. Specifically, with respect to construction contract revenues and costs, we identified deficiencies in the controls to verify that
unbilled services at the closing date of the financial statements were completely and accurately identified and recorded, projected margins by project/work were reasonable, supported and accurately calculated, and revenues billed related to actual
transactions were authorized by the customer and stated at the correct amounts. Further, with respect to contingent revenues, we did not have effective controls to verify that revenues that were contingent in nature were not recognized until all of
the recognition criteria were met. We identified deficiencies in design and operational effectiveness of the controls over the valuation of provisions for revenue. Specifically, we identified deficiencies in the controls to ensure the provisions
stated in the financial statements were recoverable and were not impaired.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Deficiencies in the determination of related estimates and the accounting for inventory and inventory entries received: We identified deficiencies in design and operational effectiveness of the controls related to the
accounting for inventory and inventory entries received. Specifically, one of our subsidiaries has not implemented the controls in all locations where they receive inventories. Also, we identified deficiencies in the design and operational
effectiveness of the control over the review, approval and documentation related to purchases of services.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Deficiencies in design and operational effectiveness of the controls over the review and approval of the valuation of acquired assets and liabilities as part of a step acquisition: We identified deficiencies in the
controls to verify the data, assumptions, model and calculations used to value acquired assets and liabilities were appropriate and reasonable.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Information and Communication

We
identified deficiencies in the controls over information and communications. Specifically, we identified deficiencies in the process to verify all information necessary to be provided to the accounting department to achieve complete and accurate
financial reporting from other operating departments were provided completely, accurately and on a timely basis.

Monitoring and Evidential Matter

Deficiencies in operational effectiveness of controls over SOX compliance: we identified deficiencies in design and operational
effectiveness of the monitoring controls related to the design and operational effectiveness of our internal controls. Specifically, we did not maintain personnel and systems within the internal audit function that were sufficient to ensure the
adequate monitoring of control activities. This control deficiency resulted in some instances of the internal audit functions failure to identify or sufficiently follow through on the analysis of certain inappropriate accounting decisions and
changes in accounting methodology.

We did not consistently maintain sufficient evidential matter, including documentation, to provide
reasonable support for managements assessment of the effectiveness of internal control over financial reporting.

Conclusion

These material weaknesses resulted in adjustments to the accounting for revenue and accounts receivable and a number of adjustments and
reclassifications in other accounts receivables owed to prepaid expenses, acquired assets and liabilities as part of a step acquisition, the classification to calculate the exchange gains/losses related to loans with related entities, and
intercompany transactions. Additionally, these material weaknesses could result in other misstatements in our financial results and disclosures, which could result in a material misstatement to our annual or interim consolidated financial statements
not being prevented or detected. Because of these material weaknesses, management concluded that we did not maintain effective internal control over financial reporting as of December 31, 2016, based on criteria in Internal Control-Integrated
Framework (2013) issued by the COSO.

Moore Stephens SCAI S.A. (a member firm of Moore Stephens International), an independent
registered public accounting firm, which has audited and reported on the consolidated financial statements as of and for the year ended December 31, 2015 and 2016 contained in this annual report on Form
20-F, has issued an attestation report on our internal control over financial reporting as of December 31, 2015 and 2016.

Remediation Plan

We continue to evaluate
our internal control over financial reporting and are taking remedial actions to address the material weaknesses that have been identified.

Our board of directors established a new Risk, Compliance and Sustainability Committee in March 2017, which is charged with, among other
things, risk management. We believe that the role of the new committee reflects, along with the role of the Audit and Process Committee and our senior management, the priority that our company gives to the improvement of our enterprise and fraud
risk management, internal control environment and will reinforce from the top of our company a culture of compliance with internal controls across our subsidiaries and other entities.

In addition, our internal audit function is being reorganized, and new personnel with the appropriate training and experience is being hired
by us to ensure that the internal control system and processes are executed in an adequate and timely manner.

Our management is
communicating to employees the need for effective internal control over financial reporting and is having meetings with process owners to reinforce the purpose and importance of controls, review and analyze the identified deficiencies, and promote top-down ownership and accountability over the control environment. Also, we will be conducting a formal training program, including related to IFRS, at our subsidiaries with employees responsible for our internal
controls to ensure they have an appropriate level of knowledge of and build the experience with those controls, specifically, those relating to monitoring, evaluation and accountability, in order to execute their control responsibilities.

We are in the process of reviewing our employees access to our accounting and key systems and we are designing and implementing new
information technology tools in order to improve our control process over the segregation of accounting duties and for the proper custody and recording of all supporting documentation, including information related to contracts.

Furthermore, moving forward, we will continue to monitor and assess our remediation activities to address the material weaknesses discussed
above through remediation as soon as practicable.

The implementation of these measures may not fully address the material weaknesses in
our internal control over financial reporting described above. Such material weaknesses have not been, nor can we ensure by what date they will be, fully remediated. The process of designing and implementing an effective reporting system is a
continuous effort that requires us to anticipate and react to changes in our business and the economic and regulatory environments and to expend significant resources to maintain a financial reporting system that is adequate to satisfy our reporting
obligations. See Item 3. Key Information D. Risk FactorsWe have identified material weaknesses in our internal control over financial reporting, and if we cannot maintain effective internal control or provide
reliable financial and other information in the future, investors may lose confidence in the reliability of our consolidated financial statements, which could result in a decrease in the value of our ADSs. If we fail to implement and maintain
an effective system of internal control, we may be unable to accurately report our results of operations or prevent fraud or fail to meet our reporting obligations, and investor confidence and the market price of our ADSs may be materially and
adversely affected.

D. Changes in Internal Control Over Financial Reporting

We identified material weaknesses in our internal control as described in Item 15.B. above. There were no other changes in our internal control
over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the year ended December 31, 2016 that have
materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 
16. [RESERVED]

Item 16A AUDIT COMMITTEE FINANCIAL EXPERT

Mr. Manuel del Rio and Mr. José Antonio Rosas each qualify as an audit committee financial expert and are
independent in accordance with SEC rules.

Item 16B CODE OF BUSINESS CONDUCT AND ETHICS

We are committed to responsible, honest, transparent and ethical conduct. Our management system enables us to communicate our corporate values
and principles to all levels of the organization, offers a confidential reporting mechanism (canal ético), and has a governance structure to investigate and remedy potential breaches of our code.

We have adopted a code of conduct and it applies to our directors, officers and employees. Our code of conduct is available on our website
www.granaymontero.com.pe. Information on our website is not incorporated by reference in this annual report.

If we make any
substantive amendment to the code of conduct or if we grant any waiver, including any implicit waiver, from a provision of the code of conduct that applies to our chief executive officer, chief financial officer or controller, we will disclose the
nature of such amendment or waiver in our website or in our next Form 20-F to be filed with the SEC to the extent required under applicable rules. During the year ended December 31, 2016, no such
amendment was made or waiver granted.

In 2015, we reinforced our ethics management system as a preventative measure. Our board of
directors approved an anti-corruption compliance program, which establishes the leadership and commitment of senior management on this matter, defines supervisory bodies and the reporting lines, establishes new policies and procedures, identifies
additional internal controls, and proposes training plans for the entire organization. This program applies to all companies in the group and to any third parties that may act on our behalf. Within the program, the anti-corruption policy provides
the guidelines required to avoid acts of corruption in our business or in our relations with any state entity, and reinforces the obligation to have accounting records and internal controls.

During 2016, our efforts regarding compliance and prevention were focused on the deployment of the anti-corruption program across our
companies. As part of this process, we implemented in our web-based platform, a training program with respect to the principal anti-corruption guidelines. Additionally, we have included anti-corruption matters
in our board of directors periodic agenda, and we also have established a compliance officer who reports to the Audit and Processes Committee. We continue performing due diligence in connection with acquisitions, and used the Know Your
Partner initiative (2015), through which preventive assessments were performed on potential strategic partners, suppliers and potential recipients of grants in 2016. In this regard, anti-corruption clauses were included in contracts with
suppliers and a specific procedure was implemented for charitable donations.

In February 2017, our board of directors created the Risk,
Compliance and Sustainability Committee to enhance our ethics and compliance program. That committee then created the Risk and Compliance Corporate Function, which reports to the committee. A new Chief Risk and Compliance Officer for the Group was
appointed to enhance and develop further our ethics and compliance program. Our board of directors also appointed an External Advisory Council to provide the Board with independent advice and recommendations on corporate governance and compliance
matters. We launched in 2017 training sessions combined with specialized courses addressed to middle and senior managers as well as to all members of our board of directors.

In December 2017, the Group launched a project to renew our Code of Ethics. We are bringing together, in a single and enhanced document, our
current Ethics Charter and our Code of Conduct. The launch of the new Code of Ethics is planned for the second half of 2018 and will come with revised training and communication campaigns on values, conduct, the compliance program and our
confidential reporting mechanism.

In January 2018, we continued to reinforce our compliance program by launching new projects that
include an enhanced due diligence policy, a revised policy on donations and a strengthened manual on relationships with government officials.

Item 16F CHANGE IN REGISTRANTS CERTIFYING ACCOUNTANT

(a) Dismissal of Independent Registered Public Accounting Firm

The company and Gaveglio, Aparicio y Asociados S.C. de R.L., a member firm of PricewaterhouseCoopers (PwC) determined that PwC
lacked independence from the company with respect to the companys financial statements for the fiscal year 2016 as a consequence of non-audit services provided by PwC to the company beginning in the
fourth quarter of the fiscal year 2016. The services related to the companys testing of internal controls in accordance with the Sarbanes-Oxley Act. As a result, the company and PwC mutually agreed on October 4, 2017 to the companys
dismissal of PwC as auditor of the companys consolidated financial statements for the fiscal year 2016. The companys Audit and Process Committee and Board of Directors participated in and approved the decision to dismiss PwC and
recommended the appointment of the companys new independent registered public accounting firm.

(b) New Audit of 2015

The independence issue described above did not affect the independence of PwC with respect to PwCs audit of the companys
consolidated financial statements for the fiscal years 2014 and 2015. The audit reports of PwC on the companys consolidated financial statements for the fiscal years 2014 and 2015 did not contain any adverse opinion or a disclaimer of opinion
and were not qualified or modified as to uncertainty, audit scope or accounting principles.

On or about March 23, 2018, PwC informed
the company that it would not authorize the use of its 2015 audit opinion in connection with the filing of the companys annual report on Form 20-F without conducting substantial additional procedures.
PwC could not give any assurance as to when it could complete such additional procedures and stated it could take several months. PwC informed the company that professional standards required the performance of substantial additional procedures with
respect to the 2015 consolidated financial statements because of publicly reported procedural developments since the firms dismissal in October 2017 concerning the cumulative effect of the decision of the Peruvian court to include three former
executives of the company and the company in its ongoing criminal investigation relating to projects involving Odebrecht, coupled with a 2015 agreement that was first provided to PwC in May 2017 while PwC was conducting the audit for the fiscal year
2016.

On April 17, 2018, to avoid further delay, the company appointed Moore Stephens SCAI S.A. (Moore Stephens) as its
new independent registered public accounting firm for the fiscal year 2015 and announced that the previously issued consolidated financial statements of the company for the 2015 fiscal year (and the related audit opinion of PwC) should no longer be
relied upon. Among other factors, as the companys current auditor, Moore Stephens, was in the process of completing its audit work with respect to the 2016 fiscal year (see (d) below) and thus, in the companys view, could more
timely and efficiently complete the 2015 audit processes as well.

(c) Disagreements and Reportable Events

During the 2015 and 2016 fiscal years and the subsequent interim period through October 4, 2017, there were no disagreements
(as described in Item 16.F(a)(1)(iv) of Form 20-F) with PwC on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures, which disagreements, if not
resolved to the satisfaction of PwC, would have caused them to make reference thereto in their reports on the financial statements for such years.

During the 2015 and 2016 fiscal years and the subsequent interim period through October 4, 2017, there were reportable events
(as that term is defined in Item 16.F(a)(1)(v) of Form 20-F) as follows: (i) as disclosed in the companys annual report on Form 20-F for the 2015 fiscal year,
the companys management and PwC each concluded that the company did not maintain effective internal control over financial reporting as of December 31, 2015, because of a material weakness related to inadequate controls over segregation
of duties in certain activities in some subsidiaries; (ii) PwC advised the company that the company did not maintain effective internal control over financial reporting as of December 31, 2016 as a result of the material weaknesses
described in Item 15.B of this annual report, except that the following items were not advised by PwC: (1) inadequate oversight by the Audit Committee regarding the role of the Internal Audit Department, (2) a control environment not
always sufficient to ensure adequate enterprise risk management (including fraud risk), and (3) the conclusion which states that there were no significant impacts in our consolidated financial statements because clarifying addendums were signed
by the parties; and (iii) at the time of PwCs dismissal, as described in (a) above, PwCs audit of the consolidated financial statements for the fiscal year 2016 was not complete, including the final resolution of matters
related to the accounting for two contracts and any related implications from the finalization of the internal investigation conducted by the company.

The Audit and Process Committee of the company discussed the subject matter of each of the
reportable events with PwC. The company authorized PwC to fully respond to the inquiries of the successor accountant concerning these reportable events.

The company has requested that PwC furnish it with a letter addressed to the SEC stating whether or not it agrees with the above statements. A
copy of such letter, dated May 15, 2018, is filed as Exhibit 16.01 to this annual report.

(d) Appointment of New Independent
Registered Public Auditing Firm

A shareholders meeting of the company held on November 2, 2017 appointed Moore Stephens as
the new independent auditor for the fiscal year 2016.

On April 17, 2018, the Audit and Process Committee of the company appointed
Moore Stephens to audit the 2015 fiscal year. The shareholders meeting of the company held on May 14, 2018 ratified the appointment.

During the 2015 and 2016 fiscal years and the subsequent interim period through April 16, 2018, the company did not consult with Moore
Stephens regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the companys consolidated financial statements, other
than in connection with the ongoing audit work by Moore Stephens of the companys consolidated financial statements for the 2016 fiscal year; or (ii) any matter that was either the subject of a disagreement or a reportable event.

Item 16G CORPORATE GOVERNANCE

We are a foreign private issuer within the meaning of the New York Stock Exchange corporate governance standards. Under New York
Stock Exchange rules, a foreign private issuer may elect to comply with the practices of its home country and not to comply with certain corporate governance requirements applicable to U.S. companies with securities listed on the exchange.

We currently follow certain Peruvian practices concerning corporate governance and intend to continue to do so. There are significant
differences in the Peruvian corporate governance practices as compared to those followed by United States domestic companies under the New York Stock Exchanges listing standards.

The New York Stock Exchange listing standards provide that the board of directors of a U.S. listed company must have a majority of independent
directors. Under Peruvian corporate governance practices, a Peruvian company is not required to have a majority of independent members on its board of directors. However we currently have a majority of independent directors on our board in
accordance with Peruvian and NYSE independence standards. Our Audit and Process Committee is comprised of independent directors under SEC rules applicable to foreign private issuers. Additionally, our Human Resources Management Committee is
currently comprised of independent directors, while our Investment Committee and our Risk, Compliance and Sustainability Committee are currently comprised of a majority of independent directors, in each case under Peruvian and NYSE independence
standards. Our Human Resources Management Committee is not the equivalent of, or wholly comparable to, a U.S. compensation committee.

The
listing standards for the New York Stock Exchange also require that U.S. listed companies have a nominating/corporate governance committee and a compensation committee (in addition to an audit committee). Each of these committees must consist solely
of independent directors and must have a written charter that addresses certain matters specified in the listing standards. Under Peruvian law, a Peruvian company may, but is not required to, form such committees, which may be composed partially or
entirely of non-independent directors. Accordingly, we do not have a nominating/corporate governance committee and a compensation committee.

In addition, New York Stock Exchange rules require the independent non-executive directors of U.S.
listed companies to meet on a regular basis without management being present. There is no similar requirement under Peruvian law, accordingly, we do not have such meetings.

The New York Stock Exchanges listing standards also require U.S. listed companies to adopt and disclose corporate governance guidelines.
In July 2002, the Peruvian Securities Commission and a committee comprised of regulatory agencies and associations prepared and published a list of suggested non-mandatory corporate governance guidelines
called the Principles of Good Governance for Peruvian Companies. These principles are disclosed on the Peruvian Securities Commission web page http://www.smv.gob.pe and the Lima Stock Exchange web page
http://www.bvl.com.pe. Although we have implemented a number of these measures and have been selected to form part of the Best Corporate Governance Practices Index of the Lima Stock Exchange, we are not required to comply with the referred
corporate governance guidelines by law or regulation.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Graña y Montero S.A.A. and its subsidiaries

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated statements of financial position of Graña y Montero S.A.A. and its subsidiaries (the Company)
as of December 31, 2015 and 2016, the related consolidated statements of operations, comprehensive loss, changes in equity and cash flows for each of the years then ended, and the related notes. In our opinion, the financial statements present
fairly, in all material respects, the financial position of the Company as of December 31, 2015 and 2016, and the results of their operations and their cash flows for each of the years then ended, in conformity with International Financial
Reporting Standards as issued by the International Accounting Standards Board. Also, in our opinion, the Company did not maintain, in all material respects, effective internal control over financial reporting as of December 31, 2015 and 2016,
based on criteria established in Internal ControlIntegrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) because the following material weaknesses in internal control over
financial reporting existed as of those dates:



|- | Lack of a formally established and documented process for enterprise and fraud risk management.
|- | -----------------------------------------------------------------------------------------------



|- | Deficiencies in the design and operational effectiveness of controls over segregation of duties to help ensure that personnel with potential conflicts were not involved in incompatible activities.
|- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|- | Deficiencies in the design and operational effectiveness of the controls established in the accounting closing process with respect to the review of the consolidated and separate financial statements, including controls
over the review, approval and documentation related to journal entries.
|- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|- | Deficiencies in the design and operational effectiveness of controls established with respect to the recognition of revenue and determination of related estimates, including construction contract revenues and contingent
revenues, and the accounting for inventory.
|- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|- | Deficiencies in the design of controls over the timely accounting for signed contracts.
|- | ---------------------------------------------------------------------------------------



|- | Deficiencies in design and operational effectiveness of the controls over the review and approval of the valuation of acquired assets and liabilities as part of a step acquisition.
|- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|- | Lack of adequate supervision, monitoring and follow-up by the Audit Committee regarding the role of the Internal Audit Department.
|- | ----------------------------------------------------------------------------------------------------------------------------------



|- | Deficiencies in operational effectiveness of controls over SOX compliance.
|- | --------------------------------------------------------------------------

A material weakness is a
deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a
timely basis. The material weaknesses referred to above are described in Management Report on Internal Control over Financial Reporting appearing under Item 15. We considered these material weaknesses in determining the nature, timing, and extent of
audit tests applied in our audits of the 2015 and 2016 consolidated financial statements, and our opinion regarding the effectiveness of the Companys internal control over financial reporting does not affect our opinion on those consolidated
financial statements.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and
procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management
and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Emphasis of Certain Matters

As discussed in Note 1 to the financial statements, Peruvian prosecutors included three former executives of the Company in an investigation for the alleged
crimes of collusion and money laundering, and included Graña y Montero S.A.A and GyM S.A. as subjects of investigation and as third parties responsible on a civil basis. The Note also describes the results of an independent investigation and
estimates that the cases will be resolved in a manner favorable to their interests. We are not able to anticipate the final result of those undertakings and the possible contingencies which may arise.

As discussed in Note 2.30 to the consolidated financial statements, the Company made adjustments to the consolidated financial statements as of
December 31, 2015, which were presented in the previous Form 20-F. These adjustments consisted of reversals of estimates of work in progress and impairments of accounts receivable for S/
44.7 million, as well as corrections in the recording of goodwill for S/ 14.7 million, reversal of deferred tax asset for S/ 23.4 million and other items for S/ 3.3 million.

Basis for Opinion

The Companys management
is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the Managements Report on
Internal Control over Financial Reporting referred to above. Our responsibility is to express opinions on these financial statements and on the Companys internal control over financial reporting based on our audits.

We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the
amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our
audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating
effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

| | b) | Authorization for issue of the financial statements

The consolidated financial statements for
the year ended December 31, 2016 were prepared and issued with Management and Board of Directors authorization on May 15, 2018 and will be submitted for consideration and approval at the General Shareholders Meeting. Management
expects that the consolidated financial statements as of December 31, 2016 will be approved with no changes.



| | c) | Current situation of the Company
| | -- | --------------------------------



| | i) | Legal Status
| | -- | ------------



| | (A) | Projects conducted in association with Odebrecht
| | --- | ------------------------------------------------

Our company participated as minority
shareholder in certain entities that developed six infrastructure projects in Peru with Odebrecht. In 2016, Odebrecht entered into a Plea Agreement with the authorities of the United States Department of Justice and the Office of the District
Attorney for the Eastern District of New York by which it admitted the commission of corrupt acts in connection to two these projects (sections 2 and 3 of the Interoceánica Sur highway (IIRSA Sur) and the project to construct the
Tren Eléctrico). As a consequence of this agreement, the Peruvian authorities initiated investigations.



| | (I) | IIRSA Sur
| | --- | ---------

With respect to the investigations conducted in relation to IIRSA Sur, the Public
Prosecutors Office included the former Chairman of the Board of Directors, for bribery; a former Director, and a former executive of the company, for money laundering.

Subsequently, Graña and Montero S.A.A. and GyM S.A. were incorporated as subjects investigated in the case described above. The
companies have appealed this judgment and the appeals are pending resolution by the Superior Court.

In addition, the Peruvian authorities has requested incorporation of Graña y Montero
S.A.A. as third party responsible on a civil basis and the Company has filed an opposition to the governments motion. Oral arguments will be made before the court on a hearing that is yet to be scheduled.

The Company believes that it has a solid defense and that therefore, the case would be resolved in its favor.



| | (II) | Electric Train
| | ---- | --------------

The Peruvian authorities also requested to incorporate GyM S.A. as a third
party responsible on a civil basis in the case related to the project to construct the electric train. The Company has filed an opposition. Oral arguments will be made before the court on a hearing that is yet to be scheduled.

The Company believes that it has a solid defense and that therefore, the case would be resolved in its favor.



| | (B) | The Constructor Club
| | --- | --------------------

On July 11, 2017, Commision de libre competence of
Indecopi initiated an investigation against several construction companies, including GyM S.A., about the existence of an alleged cartel called the Constructor Club, gathering information from the Company. Throughout the investigation,
the Company has provided to the Indecopi with all the information requested.

The Companys former commercial manager is under a
criminal investigation, as well as other individuals related to other construction companies. However, the Company is not included in this case.

To the date the result of the case described is uncertain because it is in the preliminary phase and depends on the action of the third parties
that have been included in it, However, management believes that the contingency to which the Company is exposed should not have a significant financial impact due to the lack of links I has with the alleged facts.



| | (C) | Anticorruption Law application to the Company
| | --- | ---------------------------------------------

Law 30737 and its regulation issued by Supreme
Decree 096-2018-EF has mitigated the Companys exposure to the cases described in sub sections (A) and (B) above. These rules set clear guidelines to estimate
the potential compensation that would be paid by the Company in the improbable case that it would be convicted. Furthermore, these rules have significantly reduced the uncertainty derived from the legal proceedings, by among other things, preventing
the imposition of liens or attachments of assets that would impair the ability of the Company to operate.

The benefits of the mentioned
rules are subject to the fullfilment of the following obligations:



| |  |  | The obligation to set up a trust that will guarantee any potential payment obligation of an eventual civil compensation and the interests in favor of the Peruvian State;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The obligation not to transfer funds abroad without the prior consent of the Ministry of Justice;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | The implementation of a compliance program; and
| | - |  | -----------------------------------------------



| |  |  | The obligation to disclose information to the authorities and to collaborate in the investigation.
| | - |  | --------------------------------------------------------------------------------------------------

The Company has designed a robust compliance program which is currently under implementation. In addition, it fully cooperates with the
authorities in its investigations of the alleged facts. It is also engaged in preliminary works necessary to set up the trust while it receives from the authorities the amount of the trust. Management estimated that it would need to assign to the
trust assets worth approximately USD 41 million and that its potential liability should not exceed USD 51 million.

| | ii) | Independent Investigation related to Company business with Odebrecht S.A.
| | --- | -------------------------------------------------------------------------

On
January 9, 2017, the Company Board of Directors approved a plan to conduct an independent investigation related to six projects executed in association with Odebrecht.

On March 30, 2018, the Board of Directors created a Risk, Compliance and Sustainability Committee who was in charge of the oversight of
the investigation independent from management. The investigation was entrusted to Simpson, Thatcher and Bartlett that reported exclusively to the Risk, Compliance and Sustainability Committee to preserve its independence.

The independent investigation concluded on November 2, 2017, and found no evidence that the Group or any of its former or current
directors or executives had intentionally or knowingly participated in acts of corruption related to the 6 projects developed in association with Odebrecht.

Subsidiaries are entities over which the Company has control. Subsidiaries are
fully consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases.

The Group applies the acquisition method to account for business combinations. Identifiable assets acquired, liabilities and contingent
liabilities assumed in a business combination are measured initially at their fair values at the acquisition date.

##### Table of Contents

(All amounts expressed in thousands of S/ unless otherwise stated)



The Group evaluates measurement of the
non-controlling interest on an acquisition-by-acquisition basis. At December 31, 2015 and 2016, the measurement of the non-controlling interest in the Groups acquisitions was made at the non-controlling interests proportionate share of the recognized amounts of the acquirees
identifiable net assets.

Business acquisition-related costs are expensed as incurred.

Any contingent consideration assumed by the Group with the selling party is recognized at fair value at the acquisition date. Subsequent
changes to the fair value of the contingent consideration is recognized in accordance with IAS 39 as profit or loss.

Goodwill is initially
measured as the excess of the acquisition cost, the fair value at the acquisition date of any interest previously acquired plus the fair value of the non-controlling interest, over the net identifiable assets
acquired and liabilities and contingent liabilities assumed. If the acquisition cost is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized in profit or loss at the time of acquisition.

For consolidating subsidiaries, balances, income and expenses from transactions between Group companies are eliminated. Profits and losses
resulting from inter-company transactions that are recognized as assets are also eliminated. If required, accounting policies of subsidiaries are changed where necessary to ensure consistency with the policies adopted by the Group.



| | b) | Changes in ownership interests in subsidiaries without change of control
| | -- | ------------------------------------------------------------------------

Transactions with non-controlling interests that do not result in loss of control are accounted for as equity transactions, in other words as transactions with owners in their capacity as owners. The difference between fair value of
any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interest, are also recorded
in equity at the time of disposal.



| | c) | Disposal of subsidiaries
| | -- | ------------------------

When the Group ceases to have control over a subsidiary, any retained
interest in the entity is re-measured at its fair value at the date when control is lost, with the change in carrying amount recognized in profit or loss at such date. The fair value is the initial carrying
amount for the purposes of subsequently accounting for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for
as if the Group had directly disposed of the related assets or liabilities. This may mean that the amount previously recognized in other comprehensive income is reclassified to profit or loss.



| | d) | Joint arrangements
| | -- | ------------------

Contracts in which the Group and one or more of the contracting parties
have joint control on the relevant joint activities are called joint arrangements.

Investments in joint arrangements are classified as
either joint operations or joint ventures depending on the contractual rights and obligations of each investor. The Group has assessed the nature of its joint arrangements and determined them to be both joint ventures as well as joint operations.

Joint ventures are accounted for using the equity method. Under the equity method of accounting, interests in joint ventures are initially
recognized at cost and adjusted thereafter to recognize the Groups share of the post-acquisition profits or losses and movements in the comprehensive income statement.



F-13

##### Table of Contents

(All amounts expressed in thousands of S/ unless otherwise stated)



The Group assesses on an annual basis whether there is any objective evidence that the
investment in the joint ventures and associate is impaired. If this is the case, the Group calculates the amount of impairment as the difference between the recoverable amount of the associate and its carrying value and recognizes the impairment
loss in share of profit or loss in associates and joint ventures under the equity method of accounting in the income statement.

Joint operations are joint arrangements whereby the parties that have joint control of the arrangement, have rights over the assets, and
obligations for the liabilities, relating to the arrangement. Each party recognizes its assets, liabilities, revenue and cost and its share of any asset or liability jointly held and on any revenue or cost arisen from the joint operation.

In the Group, joint operations mainly relate to consortiums (entities without legal personality) created exclusively for the development of a
construction contract. Considering that the only objective of the consortium is to develop a specific construction contract, all costs and revenue are included within revenue from construction activities and cost of construction activities,
respectively.



| | e) | Associates
| | -- | ----------

Associates are all entities over which the Group has significant influence but not
control, generally accompanying a holding of between 20% and 50% of the voting rights. Investments in associates are accounted for using the equity method of accounting (see section d above).

Profits and losses resulting from transactions between the Group and its associates are recognized in the Groups financial statements
only to the extent of unrelated investors interests in the associates. Unrealized losses are eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates are changed where
necessary to ensure consistency with the policies adopted by the Group.

Impairment losses are measured and recorded in accordance with
section d) above.



|2.3 | Segment reporting
|--- | -----------------

Operating segments are reported in a consistent manner with internal
reporting provided to Management of the Group.

If an entity changes the structure of its internal organization in a manner that causes the
composition of its reportable segments to change, the Group restates the information for earlier periods unless the information is not available.



|2.4 | Foreign currency translation
|--- | ----------------------------



| | a) | Functional and presentation currency
| | -- | ------------------------------------

The consolidated financial statements are presented in
Peruvian Soles, which is the Companys functional currency and the Groups presentation currency. All subsidiaries, joint arrangements and associates use the Peruvian Sol as their functional currency, except for foreign entities, for which
the functional currency is the currency of the country in which they operate.



| | b) | Transactions and balances
| | -- | -------------------------

Foreign currency transactions are translated into the functional
currency using the exchange rates at the date of the transactions or valuation when items are re-measured. Foreign exchange gains and losses resulting from the settlement of such transactions are recognized in
the consolidated income statement, except when deferred in other comprehensive income.

Exchange differences arising on loans from the
Company to its subsidiaries in foreign currencies are recognized in the separate financial statements of the Parent and individual financial statements of the subsidiaries. In the consolidated financial statements, such exchange differences are
recognized in other comprehensive income and are subsequently re-classified in the income statement on the disposal of the subsidiary or debt repayment, to the extent such loans qualify as part of the
net investment in a foreign operation.

(All amounts expressed in thousands of S/ unless otherwise stated)



Foreign exchange gains and losses of all monetary items are included in the income statement
within financial income or expense.



| | c) | Group companies
| | -- | ---------------

The results and financial position of all the Group entities (none of which
has the currency of a hyper-inflationary economy) that have a functional currency different from the presentation currency of the Group are translated into the presentation currency as follows:



| | i) | Assets and liabilities for each statement of financial position presented are translated using the closing exchange rate prevailing at the date of the consolidated statement of financial position;
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ii) | income and expenses for each income statement are translated at the average exchange rate (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates,
in which case income and expenses are translated using the exchange rate on the date of the transaction);
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | iii) | capital is translated by using the historical exchange rate for each capital contribution made; and
| | ---- | ---------------------------------------------------------------------------------------------------



| | iv) | all exchange differences are recognized as separate components in other comprehensive income (loss), within foreign currency translations adjustment.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------

Goodwill and fair value adjustments arising from the acquisition of a foreign entity are treated as assets and liabilities of the foreign
entity and are translated at the closing exchange rate. Exchange differences are recognized in other comprehensive income.



|2.5 | Public services concession agreements
|--- | -------------------------------------

Concession agreements signed between the Group
and the Peruvian Government entitle the Group, as a Concessionaire, to assume obligations for the construction or improvement of infrastructure and which qualify as public service concessions are accounted as defined by IFRIC 12, Service
Concession Arrangements. The consideration to be received from the Government for the services of constructing or improving public infrastructure is recognized as a financial asset or as an intangible asset (bifurcated model), as set forth
below.



| | The | Group manages three types of concessions, for which accounting treatment is as follows:
| | --- | ---------------------------------------------------------------------------------------



| | a) | Recognizes a financial asset to the extent that it has a contractual right to receive cash or other financial assets either because the Government secures the payment of specified or determinable amounts or because the
Government will cover any difference arising from the amounts actually received from public service users in relation with the specified or determinable amounts. These financial assets are recognized initially at fair value and subsequently at
amortized cost (the financial model).
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b) | Recognizes an intangible asset to the extent that the service agreement grants the Group a contractual right to charge users of the public service. The resulting intangible asset is measured at cost and is amortized as
described in Note 2.15 (intangible asset model).
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c) | Recognizes a financial asset and an intangible asset when the Group recovers its investment partially by a financial asset and partially by an intangible asset (the bifurcated model).
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.6 | Cash and cash equivalents
|--- | -------------------------

In the consolidated statements of financial position and cash
flows, cash and cash equivalents include cash on hand, on-demand bank deposits, other highly liquid investments with original maturities of three months or less and bank overdrafts. In the consolidated
statement of financial position, bank overdrafts are included in the balance of financial obligations as current liabilities.

|2.7 | Financial assets
|--- | ----------------



|2.7.1 | Classification
|----- | --------------

The Group classifies its financial assets in the following categories:
financial assets at fair value through profit or loss, financial assets held-to-maturity, loans and account receivables and financial assets available-for-sale. The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at
initial recognition.

As of the date of the consolidated financial statements, the Group has classified its financial assets in the
following three categories:



| | a) | Financial assets at fair value through profit or loss
| | -- | -----------------------------------------------------

Financial assets at fair value through
profit or loss are non-derivatives that are designated by the Group as at fair value upon initial recognition and are
held-for-trading. They are included in current assets in the consolidated statement of financial position. The derivative financial instruments policy is included at
Note 2.9.



| | b) | Loans and accounts receivable
| | -- | -----------------------------

Loans and receivables are
non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except for those whose maturity is greater than twelve months
after the date of the consolidated financial statements. These are classified as non-current assets on the consolidated financial position. The Groups loans and receivables comprise trade accounts
receivables, accounts receivable from related parties, other accounts receivable, unbilled work in progress and cash and cash equivalents.



| | c) | Available-for-sale financial assets
| | -- | -----------------------------------

Available-for-sale financial assets are non-derivatives that are either designated in this category or not classified in any of the other categories. They are included in non-current assets as Other Financial
Assets unless Management intends to dispose them within 12 months of the date of the statement of financial position.



|2.7.2 | Recognition and measurement
|----- | ---------------------------

Regular purchases and sales of financial assets are
recognized on the trade-date, the date on which the Group commits to purchase or sell the asset. Investments are initially recognized at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss.
Financial assets are derecognized when the rights to receive cash flows from the investments have expired or have been transferred and the Group has transferred substantially all risks and rewards of ownership. Available-for-sale financial assets are subsequently carried at fair value. Loans and receivables are subsequently carried at amortized cost using the effective interest method.

Gains or losses arising from changes in the fair value of the financial assets at fair value through profit or loss category are
presented in profit or loss within Other income and expenses, net in the period in which they arise. Dividend income from financial assets at fair value through profit or loss is recognized in the income statement as part of Other
income and expenses, net when the Groups right to receive payments is established.



F-16



---

##### Table of Contents

(All amounts expressed in thousands of S/ unless otherwise stated)



Changes in the fair value of monetary securities classified as available for sale are
recognized in other comprehensive income. When a financial asset classified as available for sale is sold or impaired, the accumulated fair value adjustments recognized in equity are reclassified to profit or loss. Dividends on available-for-sale equity instruments are recognized in the income statement as part of Other income and expenses, net when the Groups right to receive
payments is established.



|2.8 | Impairment of financial assets
|--- | ------------------------------



| | a) | Assets carried at amortized cost
| | -- | --------------------------------

At the end of each reporting period the Group assesses
whether there is objective evidence that a financial asset or a group of financial assets is impaired. If a financial asset or a group of financial assets is impaired, the impairment losses are recognized only if there is objective evidence of
impairment as a result of one or more events that occurred after the initial recognition of the asset (a loss event) and that loss event (or events) has an impact on the estimated future cash flows of the financial asset or group of
financial assets that can be reliably estimated.

For the loans and receivables category, the amount of any loss is measured as the
difference between the assets carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial assets original effective interest rate. The
carrying amount of the asset is reduced and the amount of the loss is recognized in the statement of comprehensive income. If a loan or an account receivable has a variable interest rate, the discount rate for measuring any impairment loss is the
current effective interest rate determined under the contract. As a practical expedient, the Group may measure impairment on the basis of an instruments fair value using an observable market price.



| | b) | Assets classified as available-for-sale -
| | -- | -----------------------------------------

The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or a group of financial
assets classified as available-for-sale is impaired.

For
equity investments, a significant or prolonged decline in the fair value of the security below its cost is also evidence that the assets are impaired. If any such evidence exists for
available-for-sale financial assets, the cumulative lossmeasured as the difference between the acquisition cost and the current fair value, less any impairment
loss on that financial asset previously recognized in profit or lossis removed from equity and recognized in profit or loss. Impairment losses recognized in the income statement on equity instruments are not reversed through the income
statement.



|2.9 | Derivative financial instruments and hedging activities
|--- | -------------------------------------------------------

Derivatives are initially
recognized at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value at the end of each reporting period. The method of recognizing the resulting gain
or loss depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged.

The Group
designates certain derivatives as hedges of a particular risk associated with a recognized asset or liability (fair value hedge) or a highly probable forecast transaction (cash flow hedge). Derivatives are initially recognized at fair value on the
date of subscription of the contract and are subsequently recognized at their fair value. The method to recognize the gain or loss resulting from changes in the fair values of the derivatives depends on the nature of the item being covered.

The Group documents, at the inception of the transaction, the relationship between hedging instruments and hedged items, as well as its risk
management objectives and strategy for undertaking various hedging transactions. The Group also documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly
effective in offsetting changes in fair values or cash flows of hedged items.



F-17



---

##### Table of Contents

(All amounts expressed in thousands of S/ unless otherwise stated)



The fair values of various derivative instruments used for hedging purposes and changes in
the account reserves for hedging in equity are disclosed in Note 8. The full fair value of a hedging derivative is classified as a non-current asset or liability when the remaining maturity period of the
hedged item is more than 12 months and as a current asset or liability when the remaining maturity period of the hedged item is less than 12 months. Trading derivatives are classified as a current asset or liability.

Cash flow hedge

The effective
portion of changes in the fair value of derivatives that are designated and qualify as fair value hedges is recognized as other comprehensive income. The gain or loss relating to the ineffective portion is recognized immediately in the income
statement.

Amounts accumulated in equity are reclassified to profit or loss in the periods when the hedged item affects profit or loss
(for example, when the forecasted sale that is hedged takes place).

The gain or loss relating to the effective portion of interest rate
swaps hedging variable rate borrowings is recognized in the income statement as Financial income or Financial expenses.

However, when the forecasted transaction that is hedged results in the recognition of a non-financial
asset (for example, inventory or fixed assets), the gains or losses previously deferred in equity are transferred from equity and are included in the initial measurement of the cost of the non-financial asset.
The deferred amounts are ultimately recognized in cost of goods sold in the case of inventory or in depreciation in the case of fixed assets.

When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss
existing in equity at that time remains in equity and is recognized when the forecasted transaction is ultimately recognized in the income statement. When a forecasted transaction is no longer expected to occur, the cumulative gain or loss that was
reported in equity is immediately transferred to the income statement within other income and expenses, net.



|2.10 | Trade receivables
|---- | -----------------

Trade receivables are amounts due from customers for goods or
services sold by the Companys subsidiaries. If collection is expected in one year or less, they are classified as current assets. If not, they are presented as non-current assets.

Trade receivables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method, less
any provision for impairment, except for receivables of less than one year that are stated at nominal amount which is similar to their fair values since they are short term.



|2.11 | Unbilled work in progress
|---- | -------------------------

Unbilled work in progress comprises the estimation made by
the Management of the Engineering and Construction segment related to the unbilled rights receivable for services rendered and not yet approved by the client (valuation based on the percentage of completion).

It also includes the balance of work in progress costs incurred that relates to future activities of the construction contracts and the
constructions phase in concessions (see Note 2.25 for detail on Revenue from construction and concession activities).

Changes in estimates
of contract revenues and costs can increase or decrease the estimated margin. When a change in the estimate is known, the cumulative impact of the change is recorded in the period in which it is known based on the progress made.

|2.12 | Inventories
|---- | -----------

Inventory mainly includes land, work in progress and finished properties
which are assigned to the real- estate activity. Land intended to carry out real estate projects is recognized at acquisition cost. Work in progress and finished properties comprise design costs, material, labor costs, financial costs (directly
attributable to the acquisition, construction and production of qualified assets), other indirect costs and general expenses related to the construction.

Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses. The Company
reviews annually whether inventories have been impaired identifying three groups of inventories to measure their net realizable value: i) the first group consists of land bought for future real estate projects which are compared to their net
appraisal value; if the acquisition value is higher, a provision of impairment is made; ii) the second group consists of land under construction, impairment is measured based on cost projections; if these costs are higher than selling prices of each
real estate unit, a provision is made for impairment; and iii) the third group comprises completed real estate units; these inventory items are compared to the selling prices less selling expenses; if these selling expenses are higher, a provision
for impairment is made. For the reductions in the carrying amount of these inventories to their net realizable value, a provision is made for impairment of inventories with a charge to profit or loss for the year in which those reductions occur.

It also includes material used in the construction activity. Goods and supplies correspond to goods that the Group trades as part of its
IT segment. Materials and supplies used in construction activities and IT equipment are determined under the weighted average cost method. Materials and other supplies are not written down below cost if the finished products in which they will be
incorporated are expected to generate margin.

|2.13 | Investment properties
|---- | ---------------------

Investment properties are shown at cost less accumulated
depreciation and impairment losses, if any. Subsequent costs attributable to investment properties are capitalized only if it is probable that future economic benefits will flow to the Company and the cost of these assets can be measured reliably;
if not, they are recognized as expenses when incurred.

Repair and maintenance expenses are recognized in profit and loss when they are
incurred. If the propertys carrying amount is greater than its estimated recoverable amount, an adjustment to reduce the carrying amount to the recoverable amount is recognized.

Depreciation is determined at rates calculated to write off cost, less estimated residual value, of each asset on a straight line basis over
its estimated useful life. The estimated useful lives of those properties range from 5 to 33 years.

The investment property held by the
Group consists of two Shopping Centers owned by subsidiary Viva GyM S.A. Fair value is estimated to be US$29.5 million, equivalent to S/99 million, at December 31, 2016 (US$16.7 million, equivalent to S/58 million, at
December 31, 2015). The sales stores of these properties have been leased as an operating lease with third parties.



|2.14 | Property, plant and equipment
|---- | -----------------------------

Property, plant and equipment are stated at historical
cost less accumulated depreciation and impairment losses, if any. Historical cost includes expenditure that is directly attributable to the acquisition of these items.

Subsequent costs are included in the assets carrying amount or are recognized as a separate asset, as appropriate, only when it is
probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. Repairs and maintenance expense are charged to the income statement during the financial period in which they
are incurred.

Assets under construction are capitalized as a separate component. At their completion, the cost of such assets is
transferred to their definitive category.

Replacement units are major spare parts in which depreciation starts when the units are
installed for use within the related asset.

Depreciation of machinery and equipment and vehicles recognized as Major equipment
are depreciated based on their hours of use. Under this method, the total number of work hours that machinery and equipment is capable to produce is estimated and a charge per hour is determined. The depreciation of other assets that do not qualify
as Major equipment is calculated under the straight-line method to allocate their cost less their residual values over their estimated useful lives, as follows:



|                         |  |       |                  |

|                         |  | Years |                 
|Buildings and facilities |  |       | Between 3 and 50 | 
|Machinery and equipment  |  |       | Between 4 and 10 | 
|Vehicles                 |  |       | Between 2 and 10 | 
|Furniture and fixtures   |  |       | Between 2 and 10 | 
|Other equipment          |  |       | Between 2 and 10 | 



F-20

##### Table of Contents

(All amounts expressed in thousands of S/ unless otherwise stated)



Residual values and useful lives are reviewed and adjusted as appropriate at each date of the
statement of financial position. Gains and losses on disposals are recognized in Other income and expenses, net in the income statement. Regarding joint operations that carry out construction activities, the difference between the
proceeds from disposals of fixed assets and their carrying amount is shown within revenue from construction activities and cost of construction activities, respectively.



|2.15 | Intangible assets
|---- | -----------------



| | i) | Goodwill
| | -- | --------

Goodwill arises on the acquisition of subsidiaries and represents the excess of the
purchase consideration, the amount of any non-controlling interest and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the net identifiable assets
acquired. If the total of consideration transferred, non-controlling interest recognized and previously held interest measured at fair value is less than the fair value of the net assets of the subsidiary
acquired, in the case of a bargain purchase, the difference is recognized directly in the income statement.

Goodwill acquired in a
business combination is allocated to each cash-generating units (CGU), or group of CGUs, that is expected to benefit from the synergies of the combination. Goodwill is monitored at the operating segment level.

Goodwill impairment reviews are performed at least annually and when events or changes in circumstances indicate a potential impairment. Any
impairment is recognized immediately as an expense in item Other income and expenses, net and cannot be reversed later.



| | ii) | Trademarks
| | --- | ----------

Trademarks acquired separately are shown at historical cost. Trademarks acquired in
a business combination are recognized at fair value at the acquisition date. Management has determined that these trademarks have indefinite useful lives. These trademarks have a long trajectory (between 24 and 39 years) in each market and the Group
is committed to continue investing in the long-term to extend the period over which they are expected to continue to provide economic benefits.

Trademark impairment reviews are performed at least annually and when events or changes in circumstances indicate a potential impairment. Any
impairment is recognized immediately as an expense in item Other income and expenses, net and cannot be reversed later.



| | iii) | Concession rights
| | ---- | -----------------

The intangible asset consisting of the right to charge users for the
services related to service concessions agreements (Note 2.5 and Note 6.b) is initially recorded at the fair value of construction or improvement services. Before amortization is started, an impairment test is performed; it is amortized under the
straight-line method, from the date revenue starts using the lower of its estimated expected useful life or effective period of the concession agreement.



| | iv) | Contractual relationships with customers
| | --- | ----------------------------------------

Contractual relationships with customers are assets
resulting from business combinations that were initially recognized at fair value as determined based on the expected cash flows from those relations over an estimated period of time based on the time period those customers will remain as customers
of the Group (the estimation of useful life is based on the contract terms which fluctuate between 5 and 9 years). The useful life and the impairment of these assets are individually assessed.

| | v) | Cost of developing wells
| | -- | ------------------------

Costs incurred in preparing wells to extract hydrocarbons in Blocks
I, III, IV and V, located in Talara, are capitalized as part of intangible assets. These costs are amortized over the useful lives of the wells (10 years for Blocks III, IV and V and 9 years for Block I), when is less than the period of the service
agreement signed with Perupetro.



| | vi) | Internally generated software and development costs
| | --- | ---------------------------------------------------

Development costs that are directly
attributable to the design and testing of identifiable and unique software products controlled by the Group are recognized as intangible assets when the following criteria are met:



| |  |  | It is technically feasible to complete the software product so that it will be available for use;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | management intends to complete the software product and use or sell it;
| | - |  | -----------------------------------------------------------------------



| |  |  | there is an ability to use or sell the software product;
| | - |  | --------------------------------------------------------



| |  |  | it can be demonstrated how the software product will probably generate future economic benefits;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | technical, financial and other resources are available to complete the development and to use or sell the software product; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | software expense during its development can be reliably measured.
| | - |  | -----------------------------------------------------------------

Other development
expenditures that do not meet these criteria are expensed as incurred. Development costs previously recognized as an expense are not recognized as an asset in a subsequent period. Computer software development costs recognized as assets are
amortized over their estimated useful lives, which fluctuate between 2 to 8 years.



| | vii) | Rights of use of land
| | ---- | ---------------------

Refers rights maintained by the Promotora Larcomar subsidiary S.A.
Rights of use of land are stated at historical cost less amortization and any accumulated impairment losses. The useful life of this asset is based on the agreement signed (60 years) and the effective period may be extended if agreed to the parties.
Amortization will begin when it becomes ready for its intended use by Management.



|2.16 | Impairment of non-financial assets
|---- | ----------------------------------

Assets that
have an indefinite useful life are not subject to amortization and are subject to review annually for impairment. Assets that are subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the
carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the assets carrying amount exceeds its recoverable amount.



|2.17 | Trade payables
|---- | --------------

Trade payables are obligations to pay for goods or services that have
been acquired in the ordinary course of business. Accounts payable are classified as current liabilities if payment is due within one year or less (or in the normal operating cycle of the business if longer). If not, they are presented as non-current liabilities.

Accounts payable are initially recognized at their fair value and subsequently
are amortized at amortized cost using the effective interest method, except for accounts payable less than one year that are recorded at their nominal value that is similar to their fair value due to its expiration in the short term.



|2.18 | Other financial liabilities
|---- | ---------------------------

Correspond to loans and bonds issued by the Group, which
are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently carried at amortized cost; any difference between the cash received (net of transaction costs) and the redemption value is recognized in the
income statement over the period of the borrowings using the effective interest method.



F-22

##### Table of Contents

(All amounts expressed in thousands of S/ unless otherwise stated)



Fees paid for entering into loan facilities are recognized as transaction costs of the loan
to the extent that it is probable that some or all of the facility will be drawn down. In this case, the fee is deferred until the draw-down occurs.



|2.19 | Borrowing costs
|---- | ---------------

Borrowing costs are recognized in the income statement in the period in
which they are incurred except for intangible assets and inventories (Note 18 and 15) in which the Group proceeds to capitalize borrowing costs.

General and specific borrowing costs directly attributable to acquisitions, construction or development of qualifying assets, which are assets
that necessarily take a substantial period of time (over 12 months) to get ready for their intended use or sale, are added to the cost of those assets, until assets are substantially ready for their intended use or sale. The Company suspends
capitalization of a qualifying asset during periods in which qualify asset development is interrupted .Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the
borrowing costs eligible for capitalization.



|2.20 | Current and deferred income tax
|---- | -------------------------------

Income tax expense comprises current and deferred tax.
Tax expense is recognized in the income statement, except to the extent that it relates to items recognized in other comprehensive income or equity, in which case, it is recognized in the statement of comprehensive income or directly in equity,
respectively.

The current income tax is calculated on the basis of the tax laws enacted or substantively enacted at the date of the
statement of financial position in the countries where the Company and its subsidiaries operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax
regulation is subject to interpretation. Management, where appropriate, establishes provisions on the basis of amounts expected to be paid to the tax authorities.

Deferred tax is recognized on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the
financial statements. However, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill; deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a
transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred income tax is determined using tax rates (and laws) that have been enacted or substantially enacted by
the balance sheet date and are expected to apply when the related deferred income tax asset is realized or is settled.

Deferred income tax
assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized. Deferred income tax is provided on temporary differences arising on investments in
subsidiaries and associates, except for deferred income tax liability where the timing of the reversal of the temporary difference is controlled by the Group and it is probable that the temporary difference will not reverse in the foreseeable
future.

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets
against current tax liabilities and when the deferred income tax assets and liabilities relate to income taxes levied by the same taxation authority.

|2.21 | Employee benefits
|---- | -----------------



| | a) | Profit sharing
| | -- | --------------

Peruvian entities of the Group recognize a liability and an expense for
statutory workers profit sharing under laws and regulations currently in force. Workers profit sharing is equivalent to 5% or 8% of the taxable income determined separately by each of the Groups Peruvian entities, according to the
income tax currently in force. The branch based in the Dominican Republic has a similar profit sharing scheme, with a rate of 10% on the taxable income. For Chile, workers profit sharing is a component of remuneration (equivalent to 4.75
minimum salary per year) rather than a percentage based on profits. In Colombia and Guyana no such benefits are paid to workers. In Bolivia workers profit sharing is equivalent to a one-month salary and
the total amount distributed cannot exceed 25% of companys profits determined under local regulations.



| | b) | Statutory bonuses
| | -- | -----------------

Entities of the Group recognize the expense and the related liability for
statutory bonuses based on applicable laws and regulations effective in Peru, Chile, Bolivia, Guyana and Colombia.



| | c) | Severance Compensation
| | -- | ----------------------

Employees severance payments for time of service of the Peruvian
Group staff comprise their indemnification rights, calculated in accordance with the regulations in force, which have to be deposited on bank accounts designated by workers in May and November each year. The compensation for time of service amounts
to one-months salary effective at the date of bank deposits. There is no such benefit in Chile and Guyana. The Group does not have any additional payment obligation once the annual deposits are made of
the amounts to which workers are entitled.



| | d) | Vacation leave
| | -- | --------------

Annual vacation leave is recognized on an accrual basis. Provision for the
estimated obligations of annual vacations is recognized at the date of the statement of financial position and it corresponds to one month for Peruvian employees and fifteen days for Dominican and Colombian employees per year. In Bolivia and Chile
vacation leave depends on seniority of a worker and ranges from fifteen to thirty days.



| | e) | Pension plans
| | -- | -------------

The subsidiary CAM has in place a pension plan scheme with its workers. These
commitments comprise both defined benefit and defined contribution plans. A defined benefit plan defines an amount of pension benefit that an employee will receive on retirement, usually dependent on one or more factors such as age, years of service
and compensation.

The liability recognized in the statement of financial position with respect to the defined benefit pension plan is the
present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest
rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating to the terms of the related pension obligation. In countries where there is no deep market
in such bonds, the market rates on government bonds are used.

Re-measurements arising from
experience adjustments and changes in actuarial assumptions are charged or credited to equity in other comprehensive income in the period in which they arise.

| | f) | Restructuring Cost
| | -- | ------------------

Group companies recognize the liability and the expense for employees
severance indemnities when they are incurred. Under Peruvian laws, in the event of an arbitrary termination of a worker, the related indemnities equal an additional one-month salary and a half per each year
actually worked by the terminated worker.

Under Colombian laws, this type of indemnities is determined based on the salary. Under Chilean
laws, termination indemnities equal an additional 30-day salary per each year actually worked up to a maximum 330 days.



|2.22 | Other provisions
|---- | ----------------



| | a) | General
| | -- | -------

Provisions are recognized when the Group has a present legal or constructive
obligation as a result of past events; it is probable that an outflow of resources will be required to settle the obligation; and the amount has been reliably estimated. Provisions are reviewed at year - end. If the time value of money is
significant, provisions are discounted using a pre-tax rate that reflects, when applicable, the specific risks related to the liability. Reversal of the discount due to the passage of time results in the
obligation being recognized with a charge to the income statement as a financial expense. Provisions are not recognized for future operating losses.

Contingent obligations are disclosed for possible obligations that are not yet determined to be probable. Contingent assets are not recognized
and only disclosed if it is probable that future economic benefits will flow to the Company.

b) Provision for the closure of production
wells -

The subsidiary GMP recognizes a provision for the closure of operating units that correspond to the legal obligation to close oil
production wells once the production phase has been completed. At the initial date of recognition, the liability that arises from said obligation is measured at the amount of expected cash flow discounted to present value, the same amount is
simultaneously charged to the intangible account in the statement of financial position. Subsequently, the liability will increase in each period to reflect the financial cost considered in the initial measurement of the discount, and the
capitalized cost is depreciated based on the useful life of the related asset. When a liability is settled, the Groups entities will recognize any gain or loss that may arise. The fair value changes estimated for the initial obligation and
interest rates are recognized as an increase or decrease of the carrying amount of the obligation and related asset, any decrease in the provision, and any decrease of the asset that may exceed the carrying amount of said asset is immediately
recognized in the income statement.

If the review of the estimated obligation results in the need to increase the provision and,
accordingly, increase the carrying amount of the asset, the Groups entities will also take into consideration if said increase corresponds to an indicator that the asset has been impaired and, if so, impairment tests are carried out (Note
2.16).



|2.23 | Put option arrangement
|---- | ----------------------

The Group has written put options over the equity of its
subsidiary Morelco SAS (Note 33 b) which permit the holder to put their shares of the subsidiary back to the Group over a 10 -year period. The amount that may become payable under the option upon exercise is initially recognized at the present value
of the redemption amount within other accounts payable with a corresponding charge directly to equity. The charge to equity is recognized separately as written put options over non-controlling interests,
adjacent to non-controlling interest in the net assets of the consolidated subsidiaries.

Subsequently, the financial liability is updated for changes in the assumptions on which the
estimated expected cash outflows were based and a financial component for the passage of time. The effects of this update are recognized in the income statement as Other income/expense. In the event that the option expires unexercised, the liability
is derecognized with a corresponding adjustment to equity.



|2.24 | Capital
|---- | -------

Common shares are classified as equity.

Incremental costs directly attributable to the issue of new shares or options are shown in equity, as a deduction, net of taxes, of the
proceeds.

Where any Group company purchases the Companys equity shares (treasury shares), the consideration paid, including any
directly attributable incremental costs (net of income taxes) is deducted from equity attributable to the companys equity holders until the shares are cancelled or reissued. Where such shares are subsequently reissued, any consideration
received, net of any directly attributable incremental transaction costs and the related income tax effects is included in equity attributable to the Groups equity holders.



|2.25 | Revenue recognition
|---- | -------------------

Revenue is measured at the fair value of the consideration received
or receivable. The Group recognizes revenue when the amount of revenue can be reliably measured; when it is probable that future economic benefits will flow to the entity; and when specific criteria have been met for each of the Groups
activities.

The Groups revenue recognition policy is described as follows:



| | i) | Revenue from construction activities
| | -- | ------------------------------------

Revenues from construction contracts are recognized using
the percentage-of-completion method which is based on the completion of a physical proportion of the overall work contract considering total costs and revenues estimated
at the end of the project, in accordance with IAS 11, Construction Contracts. Under this method revenues are determined based on the proportion of actual physical completion compared to the total contracted physical construction commitment.

When it is probable that the total costs of the contract will be above the related revenue, the expected loss will be immediately expensed.

When the outcome of a construction contract cannot be estimated reliably, the associated revenue is recognized to the extent costs
incurred are recoverable. Revenue is billed once approval is received by the owners of the work in progress.

In the statement of financial
position, the Company shows the net position of each contract as an asset or a liability. A contract is considered an asset when the costs incurred plus recognized earnings less the sum of all the recognized losses and assessments exceed work in
progress billings; this asset is shown in the statement of financial position as Unbilled work in progress; otherwise they are presented as a liability within Trade accounts payables.

A change order is an instruction by the customer for a change in the scope of the work to be performed under the contract that may lead to an
increase or a decrease in contract revenue. A variation is included in contract revenue when it is probable that the customer will approve the variation and the amount of revenue arising from the variation; and the amount of revenue can be reliably
measured.

(All amounts expressed in thousands of S/ unless otherwise stated)



A claim is an amount that the Group seeks to collect from the customer or third party as
reimbursement for costs not included in the contract price. Claims are included in contract revenue only when negotiations have reached an advanced stage such that it is probable that the customer will accept the claim; and the amount that it is
probable will be accepted by the customer can be measured reliably.



| | ii) | Revenue from engineering, advisory, consulting services and other services
| | --- | --------------------------------------------------------------------------

Revenues from
service contracts are recognized in the accounting period in which they are performed using the percentage of completion method, calculated based on the percentage of costs incurred. Additionally, there are contracts whereby income is recognized as
it is earned, regardless of when the related fees are received.



| | iii) | Salesof real-estate properties
| | ---- | ------------------------------

Revenue from sales of real estate properties is
recognized in the results of the period when sales occur, that is, when the properties are delivered and the risks and rewards inherent to ownership are transferred to the buyer and the collection of the corresponding receivables is reasonably
assured.



| | iv) | Revenue from IT services
| | --- | ------------------------

The sale of computer equipment includes some services to be provided
in a subsequent date to the asset sale as installation and maintenance. When sales agreements include multiple elements, the amount of the revenue is attributed to each element based on their related fair values. The fair value of each element is
determined based on the market price prevailing for each element when sold separately. Revenue derived from computer equipment is recognized when the related risks and rewards are transferred to the customer, which occurs upon delivery. Revenue
relating to each service element is recognized using the straight line method.



| | v) | Interest income
| | -- | ---------------

Interest income is recognized on a time-proportion basis, using the effective
interest method.



| | vi) | Revenue for concession services
| | --- | -------------------------------

Revenue from concession services is recognized according to
its nature. Construction and restoration activities are accounted for applying the percentage-of-completion method as described above and operation and maintenance
services in the accounting period when they are provided (see Note 2.5).



|2.26 | Construction contract costs
|---- | ---------------------------

Contract costs include all direct costs such as materials,
labor, subcontracting costs, manufacturing and supply costs of equipment, start-up costs and indirect costs. Periodically, the Company evaluates the reasonableness of the estimates used in the determination of
the percentage-of-completion. If, as a result of this evaluation, there are modifications to the revenue or cost previously estimated, or if the total estimated cost of
the project exceeds expected revenues, an adjustment is made in order to reflect the effect in results of the period in which the adjustment or loss is incurred.

When the outcome of a construction work cannot be estimated reliably, the revenue of the contract is recognized only up to the amount of the
contractual costs incurred and that are likely to be recovered.

|2.27 | Leases
|---- | ------



| | a) | The Group as a lessee
| | -- | ---------------------

Operating leases

Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases.
Payments made under operating leases, including prepayments (net of any incentives received from lessor) are charged to the consolidated income statement under the straight-line method over the lease term. The Groups major kinds of operating
leases are leases of machinery, computer equipment, printing equipment, among others.

Finance leases

Leases in which the Group assumes substantially all the risks and rewards of ownership of an asset are classified as finance leases. Each lease
payment is allocated between the liability and finance charges so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The corresponding rental obligations, net of finance charges, are
included in other payables, short- and long-term in the consolidated statement of financial position.

The interest element of the finance
cost is charged to the consolidated statement of comprehensive income over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The property, plant and equipment acquired
under finance leases is depreciated over the useful life of the asset or the lease term.



| | b) | Group as a lessor
| | -- | -----------------

The Group only has operating leases and the leased assets are stated in the
statement of financial position based on the nature of the asset. Revenue from operating leases are recognized under the straight-line method over the lease term and the incentives given to lessees reduce the revenue obtained from leases.



|2.28 | Dividend distribution
|---- | ---------------------

Dividend distribution to the Companys shareholders is
recognized as a liability in the financial statements in the period in which the dividends are approved by the Companys shareholders.



|2.29 | Significant non-operating items
|---- | -------------------------------

Significant non-operating items are separately shown in the financial statements when they are necessary to provide a more adequate understanding of the Groups financial performance. These material items are income or
expenses shown separately due to their nature or significant amount.



|2.30 | Restatement of Consolidated Financial Statements
|---- | ------------------------------------------------

Company Management identified the need
to make adjustments to the consolidated financial statements for the year 2015, so proceed to correct and restructure the financial statements as of December 31, 2015 in the items detailed below:

|---- | --------------------------------------------------------------

The Company has adopted
as of January 1, 2016 the following amendments to the IFRSs and amendments to IFRSs considered for the first time in the preparation of the financial statements:



F-28



---

##### Table of Contents

(All amounts expressed in thousands of S/ unless otherwise stated)



| |  |  | Annual improvements to IFRS, 2012-2014 cycles, which has required additional minor disclosures.
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | Acquisition of interest in an entity, amendment to IFRS 11 Joint Arrangements, this amendment clarifies that a joint operator that acquires an asset or group of assets in a joint operation that represents a
business in accordance with IFRS 3, applies the principles of IFRS 3 when accounting for the business combinations of the acquisition. This will result in a separate recognition of goodwill, if any arise in the acquisition. If the asset or group of
assets acquired does not constitute a business, the principles of IFRS 3 do not apply.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The amendment also clarifies that a joint operator that increases its interest in an existing joint operation in which the operator retains joint control does not again measure the interest previously held in the joint
operation
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Amendments to the disclosure initiatives, IAS 1 Presentation of the financial statements. The amendments intend to clarify a series of disclosure requirements that cover:
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The disclosure of significant accounting policies;
| | - |  | --------------------------------------------------



| |  |  | The application of materiality to the financial statements;
| | - |  | -----------------------------------------------------------



| |  |  | Presentation of subtotals;
| | - |  | --------------------------



| |  |  | Information to be presented in the other comprehensive income section of the performance statement; and
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | The structure of financial statements.
| | - |  | --------------------------------------

The adoption of these changes did not have a material
impact on the current year or prior years balances and they are not likely to affect future periods; however, the Group will give continuous consideration to the areas addressed in the amendments to help clear and concise information.



|3.2. | New standards, amendments and interpretations effective for financial statements of annual periods beginning on or after January 1, 2017 which have not been early adopted
|---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Amendments to IAS 7 Statement of cash flows requires the Group to include an additional disclosure that will enable users of financial statements to evaluate changes in liabilities arising from financing
activities.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Amendments to IAS 12 Income taxes clarifies i) the requirements for recognizing deferred tax assets on unrealized losses ii) the accounting for deferred tax where an asset is measured at fair value and that
fair value is below the assets tax base and iii) certain other aspects of accounting for deferred tax assets. These amendments are effective for annual financial periods beginning on or after January 1, 2017 and early application is
permitted. The Group does not expect these amendments may have a significant impact on its financial statements.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | IFRS 9, Financial instruments, addresses the classification, measurement and recognition of financial assets and financial liabilities. It replaces the guidance in IAS 39 on the classification and
measurement of financial instruments.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The standard is effective for accounting periods beginning on or after 1 January
2018. Early adoption is permitted. The Group does not expect that the changes in IFRS 9 may have a material impact on its criteria of classification and measurement of financial assets and liabilities.



| |  |  | IFRS 15, Revenue from contracts with customers, it replaces IAS 18 Revenue and IAS 11 Construction contracts and the related interpretations.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------

The new standard is based on the principle that income is recognized when the control of a good or service is transferred to a customer, in
such a way that the notion of control replaces the existing notion of risks and benefits. The new standard establishes a new five-step process that guides the revenue recognition, these are: (i) identify contracts with customers,
(ii) identify the performance obligation, (iii) determine the transaction price of the contract, (iv) allocate the transaction price to each of the performance obligations; and, (v) recognize the income as each performance
obligation is satisfied

The application of IFRS 15 may have flow-on
effects on the entitys business practices regarding systems, processes and controls, compensation and bonus plans, contracts, tax planning and investor communication.

The standard is effective for annual periods beginning on or after January 1, 2018 and early application is permitted.

The Group is in the process of estimating the effects of the application of IFRS 15; its assessment is being conducted by operating segment:
engineering and construction, infrastructure, real estate, technical services and parent company operation. At December 31, 2016, the Group has conducted qualitative assessment to identify impacts.

The Group estimates that the current procedure of revenue recognition defined according to its types of ordinary activities will not be
materially different from the current definition of the standard that is based on compliance with performance obligations, whether for a period or a point in time.

The Group is in the process of evaluating the methodology to be used for the transition of IFRS 15. At this point, despite the qualitative
evaluation, the Group cannot reasonably estimate the quantitative impacts that this standard would have on the financial statements.



| |  |  | IFRS 16 Leases, this standard replaces the current rules relating to the treatment of leases IAS 17 Leases and IFRIC 4 Contracts may contain a lease and other related interpretations.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

IFRS 16 is effective for financial periods beginning on or after January 1, 2019; early application if permitted
provided IFRS 15 is also early adopted. The Group is presently evaluating the impact of these standard on the preparation of its consolidated financial statements.



| |  |  | IFRIC 22, Foreign currency transactions and advance consideration, the new interpretation clarifies which date should be used for translation when a foreign currency transaction involves an advance
payment/receipt.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

This interpretation will impact all entities that enter into foreign currency transactions for which
consideration is paid or received in advance.

This interpretation is effective for financial periods beginning on or after January 1,
2018; early application is permitted. The Group is evaluating whether the changes introduced in IFRIC 22 may have a material impact on the qualifying criteria of date of transaction at their engineering and construction segment,
which is the one with significant advances balances.



| |  |  | IFRIC 23 Uncertainty over income tax treatments, it clarifies how the recognition and measurement requirements of IAS 12 Income taxes, are applied on the recognition and measurement of a tax
liability or asset in circumstances where there is uncertainty in the application of the tax law in concern.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Group is
required to consider whether it is probable that a taxation authority will accept an uncertain tax treatment. If an entity concludes that it is not probable that the treatment will be accepted, it should reflect the effect of the uncertainty in its
income tax accounting in the period in which that determination is made.

This IFRIC is effective for financial periods beginning on or
after January 1, 2019 and early application is permitted. The Group is evaluating the impact of this standard on its financial statements.

|4 | FINANCIAL RISK MANAGEMENT
|- | -------------------------

Financial risk management is carried out by the Groups
Management. Management oversees the general management of risks in specific areas, such as foreign exchange rate risk, price risk, cash flow and fair value interest rate risk, credit risk, the use of derivative and
non-derivative financial instruments and the investment of excess liquidity as well as financial risks, and carries out periodic supervision and monitoring.



|4.1 | Financial risk factors
|--- | ----------------------

The Groups activities expose it to a variety of financial
risks: market risk (including foreign exchange risk, price risk, fair value interest rate risk and cash flow interest rate risk), credit risk and liquidity risk.

The Groups overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse
effects on the Groups financial performance. The Group uses derivative financial instruments to hedge certain risk exposures in one of its subsidiaries and considers the use of other derivatives in the event that it identifies risks that may
generate an adverse effect for the Group in the short and medium-term.



| | a) | Market risks
| | -- | ------------



| | i) | Foreign exchange risk
| | -- | ---------------------

The Group is exposed to exchange rate risk as a result of the
transactions carried out locally in foreign currency and due to its operations abroad. As of December 31, 2016 and 2015, this exposure is mainly concentrated in fluctuations of U.S. dollar, the Chilean and Colombian Pesos. The foreign exchange
risk of the investments in Bolivia and Panama are not significant due to the volume of operations.

At December 31, 2016, the
consolidated statement of financial position includes assets and liabilities in foreign currency (mainly in U.S. dollars) equivalent to S/2,770.9 million and S/2,708.3 million, respectively (S/1,659 million and S/2,404 million,
respectively, at December 31, 2015) equivalents to US$826.6 million and US$806 million, respectively (US$486.7 million and US$704.5 million, respectively at December 31, 2015).

During 2016, the Peruvian Sol, the Chilean and Colombian Pesos were exposed against the U.S. dollar. The Groups exchange gains and losses
for 2016 amounted to S/761.8 million and S/774.3 million, respectively (S/427.2 million and S/510.1 million, respectively, in 2015 and S/357.3 million and S/401.6 million, respectively in 2014).

If at December 31, 2016 the Peruvian Sol and the Chilean and Colombian Pesos had strengthened/weakened by 2% against the U.S. dollar, with
all other variables held constant, the pre-tax profit for the year would have increased/decreased by S/0.3 million (S/1.7 million in 2015 and S/0.9 million in 2014).

At December 31, 2016 the consolidated statement of changes in equity comprises a foreign currency translation adjustment originated by its
subsidiaries. Their financial position includes assets and liabilities in functional currency equivalent to CLP$75,561.3 million and CLP$87,221.1 million, respectively (CLP$85,238 million and CLP$80,378 million, respectively at
December 2015), COP$169,774.8 million and COP$166,091.8 million, respectively (COP$265,370 million and COP$309,446, respectively at December 2015).

The Groups foreign exchange translation adjustment for 2016 amounted to S/0.6 million (expenses for S/44.6 million in 2015 and
S/20.5 million in 2014).

(All amounts expressed in thousands of S/ unless otherwise stated)



| | ii) | Price risk
| | --- | ----------

Management considers that the exposure of the Group to the price risk of its
investments in mutual funds, bonds and equity securities is low, since the invested amounts are not significant. Any fluctuation in their fair value will not have any significant impact on the balances reported in the consolidated financial
statements.



| | iii) | Cash flow and fair value interest rate risk
| | ---- | -------------------------------------------

The Groups interest rate risk mainly arises
from its long-term borrowings. Borrowings issued at variable rates expose the Group to cash flow interest rate risk. Borrowings issued at fixed rates expose the Group to fair value interest rate risk. Group policy is to maintain most of its
borrowings at fixed rate instruments; 52.8% of total debt in 2016 (72.7% in 2015) was contracted at fixed rates and 47.2% at variable rates (27.3% in 2015) which consisted of a 18.0% fixed rate plus VAC (adjusted for inflation) and the remaining
29.2% at a variable rate (23.6% fixed rate + VAC and the remaining 3.7% at a variable rate in 2015).

The debt subject to fixed rate plus
VAC is related to a bond issued in Peruvian soles to finance the GyM Ferrovías Project, Metro Line 1 (Note 20). Any increase in the interest rate resulting from higher inflation will have no significant impact on the Groups profit
because these revenues are also adjusted for inflation.

During 2016 and 2015 borrowings at variable rates are denominated in Peruvian
Soles and U.S. dollars and the Groups policy is to manage their cash flow risk by using interest-rate swaps, which are recognized under hedge accounting. However, regarding the variable rate loans related to GSP (Note 19-a), Management decided to assume the risk since it expects to pre-pay them before due. If at December 31, 2016, the libor rate plus 3 months had increased/ decreased
by 5%, with all other variables held constant, the pre-tax profit for the year would have increased/ decreased by S/1.4 million (there was not a material effect on the Groups results in 2015). There
was no material ineffectiveness on cash flow hedges occurred in fiscal years 2016 and 2015.



| | b) | Credit risk
| | -- | -----------

Credit risk arises from cash and cash equivalents and deposits with banks and
financial institutions, as well as customer credit counterparties, including the outstanding balance of accounts receivable and committed transactions. For banks and financial institutions, only independently rated parties with a minimum rating of
A are accepted.

With respect to loans to related parties, the Group has measures in place to ensure the recovery of these
loans through the controls maintained by the Corporate Finance Management and the performance evaluation conducted by the Board.

No credit
limits were exceeded during the reporting period, and Management does not expect the Group to incur any losses from performance by these counterparties, except for the ones already recorded at the financial statements.



| | c) | Liquidity risk
| | -- | --------------

Prudent liquidity risk management implies maintaining sufficient cash and cash
equivalents, the availability of funding through an adequate number of sources of committed credit facilities and the capacity to close out positions in the market. Historically, the Group cash flows enabled it to maintain sufficient cash to meet
its obligations. However, as of December 31, 2016, the Group started to experienced liquidity risk due to the early termination of the GSP concession agreement and the obligations assumed (Note 16 a-i).
As a consequence, the Group has started a disinvestment plan to be able to meet the obligations resulting from this scenario (Note 37).

(All amounts expressed in thousands of S/ unless otherwise stated)



Group Corporate Finance monitors rolling forecasts of the Groups liquidity requirements
to ensure it has sufficient cash to meet operational needs while maintaining sufficient headroom on its undrawn borrowing facilities (Note 19), so that the Group does not breach borrowing limits or covenants, where applicable, on any of its
borrowing facilities. Less significant financing transactions are controlled by the Finance Management of each subsidiary.

Such
forecasting takes into consideration the Groups debt financing plans, covenant compliance, compliance with internal statement of financial position ratio targets and, if applicable, external regulatory or legal requirements; for example,
foreign currency restrictions.

Surplus cash held by the operating entities over the balance required for working capital management are
invested in interest-bearing checking accounts or time deposits, selecting instruments with appropriate maturities and sufficient liquidity.

The table below analyzes the Groups financial liabilities into relevant maturity groupings based on the remaining period from the date of
the statement of financial position to the contractual maturity date. The amounts disclosed in the table are the contractual undiscounted cash flows.

|4.2 | Capital management
|--- | ------------------

The Groups objectives when managing capital are to safeguard
the Groups ability to continue as a going concern in order to provide returns for shareholders, benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital. As described at Note 1, in 2016 the
current situation of the Company, has lead Management to monitor deviations that might cause the non-compliance of covenants and may hinder renegotiation of liabilities
(Note19-a and Note 37-c).

In order to maintain or adjust
the capital structure, the Group may adjust the amount of dividends paid to shareholders, return capital to shareholders, issue new shares or sell assets to reduce debt.

The Group monitors capital on the basis of the gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is
calculated as total borrowings (including current and non-current borrowings), less cash and cash equivalents. Total capital is calculated as equity as shown in the consolidated statement of
financial position plus net debt.

|4.3 | Fair value estimation
|--- | ---------------------

For the classification of the type of valuation used by the Group
for its financial instruments at fair value, the following levels of measurement have been established.



|  |  |          |  |                                                                                                                                                                                                                
|- |  | -------- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| |  | Level 1: |  | Measurement based on quoted prices in active markets for identical assets or liabilities.                                                                                                                      
|  |  |         
| |  | Level 2: |  | Measurement based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (that is, as prices) or indirectly (that is, derived from prices).
|  |  |         
| |  | Level 3: |  | Measurement based on inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs, generally based on internal estimates and assumptions of the Group).        

The table below shows the Groups assets and liabilities measured at fair value at December 31, 2015
and 2016:

Financial instruments in level 3

The fair value of the investment held in Transportadora de Gas del Perú S.A. (TGP) classified as available-for-sale financial asset was based on observable inputs in the market and unobservable inputs. The Group calculated its fair value based on its discounted cash flows as of the financial statement
date. The information used to determine the fair value of this investment corresponds to Level 3 (Note 10).

The carrying amounts of cash and cash equivalents correspond to their fair values. The Company considers that
the carrying amount of trade accounts receivable and payable is similar to their fair values since they are short term. The fair value for long-term receivables and liabilities is disclosed in Note 11, Note 12, Note
19-c, Note 20 and Note 22. The fair value of financial liabilities has been estimated by discounting the future contractual cash flows at the interest rate currently prevailing in the market and which is
available to the Company for similar financial instruments (Level 2).



|5 | CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS
|- | -------------------------------------------

Estimates and judgments used are
continuously evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.



|5.1 | Critical accounting estimates and assumptions
|--- | ---------------------------------------------

The Company makes estimates and
assumptions concerning the future. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts
of assets and liabilities within the next financial year are addressed below.



| | a) | Estimated impairment of goodwill and other intangible assets with indefinite useful life
| | -- | ----------------------------------------------------------------------------------------

Impairment reviews are undertaken annually to determine if goodwill arising from business acquisitions and other intangible assets with
indefinite useful life are impaired, in accordance with the policy described in Note 2.15-i). For this purpose, goodwill is allocated to the different CGUs to which it relates while other intangible assets
with indefinite useful life are assessed individually. The recoverable amounts of the CGUs and of other intangible assets with indefinite useful life have been determined based on the higher of their value-in-use and fair value less costs to sell. This evaluation requires the exercise of Managements professional judgment to analyze any potential indicators of impairment as well as the use of
estimates in determining the value in use, including preparing future cash flows, macro-economic forecasts as well as defining the interest rate at which said cash flows will be discounted.

If the Group experiences a significant drop in revenues or a drastic increase in costs or changes in other factors, the fair value of their
business units might decrease. If management determines the factors that reduce the fair value of the business are permanent, those economic factors will be taken into consideration to determine the recoverable amount of those business units and
therefore, goodwill as well as other intangible assets with indefinite useful life may be deemed to be impaired, which may cause their write-down to be required.

Based on the impairment tests performed by Group Management, no goodwill nor intangible
(trademarks) impairment losses were required to be recognized because the recoverable amount of the CGUs subject to testing was substantially higher than their related carrying amounts.

The most significant assumptions used in impairment testing are gross margin, discount rate, terminal growth rate and revenue growth rate which
are included in Note 18.

At December 31, 2015 and 2016 the Group has performed a sensitivity analysis increasing or decreasing the
assumptions of gross margin, discount rate and revenue and terminal growth rate by a 10%, with all the other variables held constant, as follows:

In 2016 if the gross margin, the discount rate or terminal growth rate had been 10% below or 10% above
Managements estimates, respectively, the Group would have recognized a provision for impairment of goodwill of the Engineering and Construction CGU and Telecommunication Services CGU (within the Engineering and Construction CGU in 2015).

In 2016 if the revenue growth rate or terminal growth rate had been 10% below
Managements estimates, or the discount rate had been 10% above Managements estimates, the Group would have recognized a provision for impairment of their trademark Adexus.

At December 31, 2016, as a result of these evaluations, an impairment was identified and recorded in one of the CGU, Vial and Vives DSD
(Note 18).



| | b) | Income taxes
| | -- | ------------

Determination of the tax obligations and expenses requires interpretations of the
applicable tax laws and regulations. The Company seeks legal and tax counsel before making any decision on tax matters. Although Management considers its estimates to be prudent and appropriate, differences of interpretation may arise with Tax
Authorities (mainly Peruvian, Chilean and Colombian Authorities) which may require future tax adjustments.

Deferred tax assets and
liabilities are calculated on the temporary differences arising between the tax basis of assets and liabilities and the amounts stated in the financial statement using the tax rates in effect in each of the years in which the difference is expected
to reverse. Any change in tax rates will affect the deferred income tax assets and liabilities. This change will be recognized in the income statement in the period in which the change takes effect.

Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the
temporary differences and tax loss carryforwards can be utilized. For this purpose, the Group takes into consideration all available evidence, including factors such as historical data, projected income, current operations and tax planning
strategies. A tax benefit related to a tax position is only recognized if it is more likely than not that the benefit will ultimately be realized.

The Groups maximum exposure to tax contingencies amounts to S/11.3 million.



| | c) | Percentage of completion revenue recognition
| | -- | --------------------------------------------

Revenues from construction contracts are
recognized using the percentage-of-completion method which is based on the completion of a physical proportion of the overall work contract considering total costs and
revenues estimated at the end of the project (Note 2.25 i).

As of December 31, 2016, 2015 and 2014, a sensitivity analysis was
performed considering a 10% increase/decrease in the Groups gross margins, as follows:

| | d) | Provision for well closure costs
| | -- | --------------------------------

At December 31, 2016 the present value of the estimated
provision for closure of 144 wells located in Talara amounted to S/17.2 million (S/7.3 million as of December 31, 2015 for closure of 78 wells). The well closure liability is adjusted to reflect the changes that resulted from the
passage of time and from reviews of either the date of occurrence or the amount of the present value of the originally estimated obligations (Note 18).

The Group estimates the present value of its future obligation for well closure costs, or well closure liability, and increases the carrying
amount of the asset that will be withdrawn in the future and that is shown under the heading of intangibles in the statement of financial position.

The pre-tax discount rate used for the present value calculation was 1.93% for Blocks I and V, and
2.93% for Blocks III and IV, respectively, based on a 5 to 30-year rate used on U.S. bonds effective at December 31, 2016 (2.09% based on the 7-year bond rate at
December 2015 for Blocks I and V).

If, at December 31, 2016 and 2015, the estimated rate had increased or decreased by 10%, with all
variables held constant, the impact on pre-tax profit would have not been significant.



| | e) | Impairment of investment in Gasoducto Sur Peruano
| | -- | -------------------------------------------------

Based on the termination of the concession
agreement, on which Gasoducto Sur Peruano S.A. (GSP) acts as concessionaire (Note 16.a-i and Note 37), the Group identified potential impairment indicators affecting the recoverability of its investment.
Consequently, the Group has applied the rules stated in IAS 36, Impairment of assets to determine the recoverable amount of this investment.

In that process, the Group has applied judgement to weight the various uncertainties surround the amount that can be recovered from this
investment. Management has determined the recoverable amount assuming two key factors: (i) the amount that GSP will recover as a result of the public auction, and (ii) the validity of its right to subordinate the Odebrecht Groups
debts in GSP.

With relation to the amount to be recovered by GSP; the Group is assuming a recovery of the minimum amount established in
the concession agreement, which is equivalent to 72.25% of the Net Carrying Amount (NCA) of the Concession assets. This amount, in substance, represents a minimum secured payment to be obtained by GSP based on a public auction (liquidation) to be
set up for the adequate transfer of the Concessions assets to a new Concessionaire within a year, under the relevant contractual terms and conditions.

With relation to the validity of its right to subordinate the Odebrecht Groups liabilities in GSP, Management assessment, in consultation
with its legal advisors, is that, although some uncertainties exist, these do not represent a material risk for exercising this right.

The
concession agreement also established two additional tranches of 82.5% or 100% of the NCA to be recovered as a result of public auction, depending on several factors. In any of these scenarios, the Group would be able to recover their total
investment and no additional impairment would be necessary to be recognized.

Depending on the date in which the NCA is actually cashed,
the Group may need to take into account additional costs ranging from S/18.95 million (US$5.64 million) to S/42.2 million (US$12.56 million), due to higher financial expense.

| | f) | Impairment of the investment in Consorcio Constructor Ductos del Sur (CCDS)
| | -- | ---------------------------------------------------------------------------

CCDS was mainly
engaged in performing the engineering, procurement and construction work for GSP. Due to the early termination of GSP, the Group applied the rules stated in IAS 36 Impairment of assets and IAS 37 Provisions to determine the
recoverable amounts of the assets and liabilities to be recorded, respectively. As a result, the following adjustments were included at the financial statements:

net impact of the early termination of CCDS construction contract is a loss of S/15.2 million.



|5.2 | Critical judgments in applying the entitys accounting policies
|--- | ---------------------------------------------------------------

Consolidation
of entities in which the Group holds less than 50%

The Company owns some direct and indirect subsidiaries of which the Group has
control even though it has less than 50% of the voting rights. These subsidiaries mainly comprise indirect subsidiaries in the real-estate business owned through Viva GyM S.A., where even though the Group holds interest between 30% and 50%, has the
power to affect the relevant activities that impact the subsidiaries returns. Additionally, the Group has de facto control over Promotora Larcomar S.A. of which it owns 46.55% of equity interest.

Consolidation of entities in which the Group does not have join control but have rights and obligations over the assets and liabilities

The Group assesses, on an ongoing basis, the nature of the contracts signed with one or more parties. If no control or joint control
is determined to be held by the Group but it has rights to assets and obligations for liabilities under the arrangement, then the Group recognizes its assets, liabilities, revenue and expenses and its share of any jointly controlled assets or
liabilities and any revenue or expense arising under the arrangement as a joint operation in accordance with IFRS 11Joint arrangements (Note 2.2-d).

| | b) | Public services concessions
| | -- | ---------------------------

The Group acts as an operator in various public service
concessions. When applicable, revenue attributable to the construction or restoration of infrastructure has been accounted for by applying the models set forth in Note 2.5 (financial asset, intangible asset and bifurcated models).

Subsidiary Transportadora de Gas Natural Comprimido Andino S.A.C. (hereinafter TGNCA) held a concession to design, finance, construct, maintain
and operate the compressed natural gas supply system to be implemented in certain cities. The Concession was recognized under the financial asset model. In September 2016 the Concession Agreement was terminated on the grounds of counterpartys
failure to meet the required conditions (availability of assets and resources). As a result, TGNCA recognized an impairment loss of receivables amounting to S/6.3 million, which is included in the income statement within cost of services
provided (Note 27). The balance remaining relates to trade accounts receivable for S/38.7 million, to be received from the Ministry of Energy and Mines. This balance was classified as current assets because Management expects a favorable
outcome of the award.

In all the Group concessions, the infrastructure is returned to grantor at the end of the concession
agreement. The concessions held by the Group are as follows at December 31, 2016:

As set forth under IFRS 8, reportable segments based on the level of revenue are:
engineering and construction and technical services. However, the Group has voluntarily decided to report on all its operating segments as detailed in this Note.

The revenues derived from foreign operations (Chile, Panama, Dominican Republic, Colombia, Bolivia, Ecuador and Guyana) comprise 25.4% of the
Groups total revenue reported in 2016 (27.1% in 2015 and 19.9% in 2014).

Sales between segments are carried out at arms
length, are no material, and are eliminated on consolidation. The revenue from external parties is measured in a manner consistent with that in the income statement. Sale of goods relate to the real state segment. Revenue from services relate to all
other segments.

Group sales and receivables are not concentrated in a few customers. There is no external customer that represents 10% or
more of the Groups revenue.

The following segments set forth the principal activities of the Group:



| | a) | Engineering and construction: This segment includes from traditional engineering services such as structural, civil and design engineering, and architectural planning to advanced specialties including process design,
simulation, and environmental services at four divisions; i) civil works, such as the construction of hydroelectric power stations and other large infrastructure facilities; (ii) electro mechanic construction, such as concentrator plants, oil
and natural gas pipelines, and transmission lines; iii) building construction, such as office buildings, residential buildings, hotels, affordable housing projects, shopping centers and industrial facilities; and iv) services related to mining, such
as earthworks, blasting, loading and hauling ore.

|10 | OTHER FINANCIAL ASSETS
|-- | ----------------------

On April 2016, the Company sold their 1.64% of interest held in
Transportadora de Gas del Perú S.A. (TGP) for S/107.3 million, resulting in a net profit of S/46.3 million, as shown in the income statement, within Profit (loss) on sale of investments. The balance of its investment at
the date of sale was S/117.1 million.

The cumulative amount of fair values at the date of sale amounting to S/41.5 million
(S/56 million of gain on fair value and S/14.6 million of income tax), as recognized in the statement of other comprehensive income was transferred to profits for the period.

At December 31, 2015 the fair value of the Groups interest in TGP equals S/120.1 million based on the discounted cash flow
method. The information used in the calculation was as follows:



| |  |  | Discounted cash flows from operating activities of TGP net of cash flows from investment activities (CAPEX).
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | Cash flows were estimated for a 30-year term.
| | - |  | ---------------------------------------------



| |  |  | The discount rate used was 7.5% corresponding to estimated TGPs WACC.
| | - |  | ----------------------------------------------------------------------



| |  |  | The interest of the Company in TGP was 1.64%.
| | - |  | ---------------------------------------------

The fluctuation in the fair value of this
investment in 2015 amounted to S/19.9 million (S/4.6 million in 2014) net of its income tax effect amounting to S/7 million (S/1.3 million in 2014), which was recognized in the statement of other comprehensive income.

In 2015 dividends from this investment were received for a total S/7.2 million (S/9.3 million in 2014) included within Other income
(Note 29).

The most significant assumptions are the discount rate and cash flows affected by the U.S. Wholesale Price Index; the Group
performed a sensitivity analysis of this assumptions: if the discount rate were adjusted down by 5% the fair value would be 7.4% lower; and if the discount rate were adjusted up by 5% the fair value would be 7.1% higher; if the cash flows were
adjusted down by 5% the fair value would be 9.1% lower and if the cash flows were adjusted up by 5% the fair value would be 8.8% higher.

In addition to the GSP acquisition described in Note 16 a-i); in 2014,
2015 and 2016 the following significant movements were noted:



| |  |  | During 2016 cash contributions were made principally to Gasoducto Sur Peruano S.A. and Concesionaria Chavimochic amounting to S/373.9 million and S/15.7 million, respectively.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In 2016 the Group obtained dividends mainly from Betchel Vial y Promoción Inmobiliaria del Sur S.A. amounting to S/6.3 million and S/3.8 million, respectively. In 2015 the Group received dividends from
Promoción Inmobiliaria del Sur S.A. amounting to S/9.8 million (from Promoción Inmobiliaria del Sur S.A., Ingeniería y Construcción Vial y Vives OGP -1 Limitada y Betchel Vial
y Vives Servicios Complementarios Ltda. for S/3.4 million, S/16.6 million and S/4.9 million, respectively in 2014).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In 2016, the Group included an impairment provision of GSP for S/593.1 million (US$176.49 million). See subsequent events after the date of the statement of financial position in Note 37.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In 2015, the share of the profit or loss in associates and joint ventures under the equity method shown in the income statement includes S/17.3 million as expenses that subsidiary GyM S.A. had to pay
for the execution of the letter of guarantee in JV Panama.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In March 2014, Constructora Norberto Odebrecht S.A. and Odebrecht Partipacoes e Investimentos S.A. formed Concesionaria Chavimochic S.A.C., in which the Company had a 26.5% interest based on a capital contribution of
S/13.3 million.

| |  |  | In December 2014, subsidiary Viva GyM S.A. made a capital contribution of S/37.8 million, by which it joined the Panama Project initially carried out by a third party and the Group and by which a 35% interest was
obtained. On December 17, 2015 the business operating structure was decided to be changed, which resulted in the extinguishment of the association and the formation of a consortium by which the partners would have joint control of the business,
with no effect on their percentage share in profit distribution. From that date onwards, the Group ceased to use the equity method of accounting to recognize the investment and began to use the joint operation accounting treatment.

As a result of the impairment testing on goodwill performed by Management on an annual basis, the recoverable
amount of the related cash-generating unit is determined based on the higher of its value in use and fair value less cost of disposal. Value in use is determined based on the future cash flows expected to be generated by the assessed CGU.

As a result of these assessments an impairment was identified in one of the CGUs, Vial y VivesDSD, and was accounted as of December
31st, 2016. The loss to impairment was generated due to the decrease in the expected flows, as a result of the reduction of the contracts linked to the Backlog. The amount of the impairment it impacted the total amount of goodwill was
S/38.7 million.

Major assumptions used by the Group in determining the fair value less cost of disposal and the value in use were as
follows:

As a result of these tests, at December 31, 2016, the Vial y Vives - DSD trademark was
partially impaired, the amount of the impairment was S/15.6 million. No provision for impairment was considered necessary to be recorded for 2015.

Major assumptions used by the Group in determining the fair value less cost of disposal are as follows:

| | c) | Concessions -
| | -- | -------------

The Concessions intangibles at December 31, 2016 mainly consist of:
i) EPC contract for S/405 million (S/317.5 million at December 31, 2015) comprising the construction of the second section of Ancón-Huacho-Pativilca highway; ii) improvement
of highway for S/18.1 million (S/19.6 million at December 31, 2015), and iii) Borrowing costs that were capitalized for a total of S/22.5 at an interest rate ranging from 7.14% y 8.72% (S/7.7 million in 2015 at an interest rates
ranging from 6.75% to 8.375%). By those contracts, the Concessionaire should perform activities to construct, improve and remediate road infrastructure during the Concession effective period.



| | d) | Costs of development of wells -
| | -- | -------------------------------

Through one of its subsidiaries, the Group operates and
extracts oil from two oil fields (Block I and Block V) located in the province of Talara in northern Peru. Both oil fields are operated under long-term service agreements by which the Group provides hydrocarbon extraction services to Perupetro.

On December 10, 2014 the Peruvian Government granted subsidiary GMP S.A. a right of exploiting for 30 years the oil blocks III and IV
(owned by the Peruvian government-run entity- Perupetro) located in Talara, Piura, 230 wells and 330 wells respectively. The total investment expected to be made in both wells is estimated to be
US$560 million; operations began in April 2015 in both blocks.

As part of the Groups obligations under the relevant service
agreements, certain costs will be incurred in preparing the wells in Blocks I, III, IV and V. These costs are capitalized as part of intangible assets at a carrying amount of S/80 million at December 31, 2016 (S/118.4 million at
December 31, 2015).

All blocks are amortized on the basis of the useful lives of the wells (estimated to be 5 years for Blocks I and
V and 10 years for Blocks III and IV), which is less than the total effective period of the service agreement with Perupetro.

| | i) | Credit Suisse Syndicated Loan -
| | -- | -------------------------------

In December 2015, the Group entered into a medium term loan
credit agreement for up to US$200 million (equivalent to S/672 million), with Credit Suisse AG, Cayman Islands Branch, Credit Suisse AG, Cayman Islands Branch and Credit Suisse Securities (USA) LLC. The initial term of the loan was set at five
years, with quarterly installments starting to be paid on the 18th month. The loan accrued interest at a rate of three months Libor plus 3.9% per year. The proceeds were used to finance the equity interest in GSP. As of December 31, 2016, the
outstanding balance amounted to US$148.5 million (equivalent to S/498.8 million), and it is included within the current portion.

On
June 27, 2017, the Group renegotiated the terms of this loan to clear breaches related to the termination of the GSP concession. The new terms require repayment by December, 2020, with required prepayments to be made with the proceeds of asset
sales of 40% in the first year and an additional 30% in the second year of the amendment. The syndicated loan accrues interest at LIBOR plus 4.90% per year. Under the amendment, the Group is prohibited from paying dividends until the loan is fully
repaid. The loan is secured by (i) a lien on Concars shares; (ii) a lien on Almontes shares; (iii) a mortgage over certain real estate properties in Miraflores and Surquillo; (iv) liens on certain accounts; (v) a
lien on GyMs share; (vi) a second lien on CAM Holding SPAs shares; (vii) a second lien on CAM Servicios del Perú S.A.s shares; and (viii) a first lien on cash flows from the sale of certain assets.

The agreement contains certain covenants, including the obligation by the Company to maintain the following financial ratios during the term of
the agreement: (1) the Consolidated EBITDA to Consolidated Interest Expense Ratio shall not be less than 3.5:1.0 commencing on April 1, 2018 and thereafter; (2) the Consolidated Leverage Ratio (as defined therein) shall not be greater
than 3.5:1.0 at any time during the period commencing on December 31, 2016 and ending on March 31, 2017; 3.5:1.0 at any time during the period commencing on July 1, 2017 and ending on September 30, 2017; and no greater than

April 1, 2018 and thereafter.

As of the date of this annual report, we are under continuing default in this financing due
to the non-delivery of the audited consolidated financial statements of Graña y Montero and GyM for the 2016 and 2017 fiscal years. The syndicated loan required that we provide the financial statements for the 2016 and 2017 fiscal years no
later than April 30, 2018. We are in the process of obtaining waivers from the lenders.

As of to date, the outstanding balance of the loan
capital is US$81.1 million (equivalent to S/264.9 million).

At December 31, 2016, the current balance includes US$129 million

US$78.7 million (equivalent to S/264.8 million), the proceeds of which were used to repay the GSP bridge loan.

The maturity is June,
2020, with required prepayments to be made with the proceeds of asset sales of 40% in the first year and an additional 30% in the second year. The new term contains the following covenant: the consolidated leverage ratio shall not be more than
3.5:1.0 at any time, and accrues interest at LIBOR plus 4.50% per year, which increases to 5.00% during the second year and 5.50% during the third year. Under the new term, the Group is prohibited from paying dividends until the loan is fully
repaid. Also, the new term is secured by (i) a first lien on rights to receive the termination payment derived from the GSP termination (the VCN), (ii) a second lien on our shares of GyM and Concar; (iii) a second lien on our
shares of Almonte; (iv) a second lien on certain real estate properties in Miraflores and Surquillo; (v) a second lien on our shares of CAM Holding SPA; (vi) a second lien on our shares of CAM Servicios del Perú S.A.; and

provide the financial statements for the 2016 and 2017 fiscal years no later than April 30, 2018. As of March 2018, (a) our Consolidated Leverage Ratio (as defined therein) was 2.62, rather than no more than 2.50 as required under the syndicated
loan and (b) [●]. We are in the process of obtaining waivers from the lenders.

##### Table of Contents

(All amounts expressed in thousands of S/ unless otherwise stated)



At December 31, 2016, legal claims mainly comprise provisions for labor liabilities and
tax claims for S/14.7 million (S/8 million at December 31, 2015). Claims with the tax authority have been accounted for based on management estimates of the amounts the Group would most likely be required to pay in regard of these
current court actions. Due to the fact those amounts will depend on the tax authority, the Group does not have an estimated timing of when these cash outflows would be required.

This legal claims balance also includes court actions brought against the Group by the Peruvian energy regulator (OSINERGMIN) resulting from
the storage of hydrocarbons and the applicable environmental laws and regulations for S/6.3 million (S/6.1 million at December 31, 2015).

The gross movement of other provisions is broken down as follows:

At December 31, 2016, total tax losses amounted to S/507.3 million of which S/22.28 million are
expected to be applied in 2017, S/57.55 million in 2018 and the remaining balance in the following fiscal years (S/334.5 million in 2015, of which S/53.6 were expected to be applied in 2016, S/56.9 million in 2017 and the remaining
balance in the following fiscal years).

Tax goodwill arose from a tax credit balance resulting from the reorganization of Chilean
subsidiaries in 2014 under Chilean tax laws and regulations. In 2016, the arbitration process relating to Project Collahuasi was completed and an additional payment was determined to be paid to the Chilean subsidiary selling party; which resulted in
a higher balance in this item.

| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b) | Changes in the Peruvian Income Tax Law -
| | -- | ----------------------------------------

By means of Law No.30296 enacted on December 31,
2014 amendments to Income Tax Law have been made, which are effective starting in fiscal year 2015 onwards. Among these amendments, it should be noted the progressive reduction in the corporate income tax rate (on the Peruvian third-category income
earners) from 30% to 28% for fiscal years 2015 and 2016; then a reduction to 27% for fiscal years 2017 and 2018; and a final reduction to 26% from fiscal year 2019 onwards. Tax on dividends and other forms of profit distribution, agreed on by any
legal entities to individuals and non-domiciled legal persons is to be progressively increased from 4.1% to 6.8% for distributions that are agreed on or paid during fiscal years 2015 and 2016; then an increase
to 8.8% for fiscal years 2017 and 2018 will be effective; and a final increase to 9.3% will be effective from fiscal year 2019 onwards. The distribution of retained earnings until December 31, 2015 will continue to be subject to a 4.1% tax even
when the distribution is to be made in the subsequent years.

By means of Legislative Decree No. 1261, enacted on December 10,
2016 the Peruvian income tax law was amended to be effective from fiscal 2017 onwards. This amendment sets forth a corporate income tax rate of 29.5%. It also sets forth an income tax rate on dividends of 5% applicable to non-domiciled legal entities and individuals effective from fiscal 2017 onwards. Undistributed profits up to December 31, 2016 will continue to be affected to a 6.8% income tax rate regardless of whether the
distribution is agreed or occurs in subsequent periods.

##### Table of Contents

(All amounts expressed in thousands of S/ unless otherwise stated)



| | i) | Attributable income system: the tax rate of first-category applicable on entities will be progressively increased, 21% in 2014, 22.5% in 2015, 24% in 2016, up to 25% in 2017. Its choice is being restricted to companies
whose partners are individuals domiciled or resident in Chile or individuals or legal persons non-domiciled and non-resident in Chile. This system levies the shareholders of Chilean entities with taxes on an
annual basis regardless of any effective distribution of profits from the local entity; and entitles them to use the total taxes paid as income tax fiscal credit.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ii) | Partially integrated system: of first-category taxes applicable on entities will be progressively increased, 21% in 2014, 22.5% in 2015, 24% in 2016, 25.5% in 2017, up to 27% in 2018. Subject to this system are
corporations and entities in which at least one of its owners is not an individual (whether domiciled or not) or non-domiciled legal entity. This system levies the shareholders of Chilean entities that
distribute dividends and entitle them to use such distribution as a fiscal credit at a 65% of the total taxes paid. This limit does not apply to investors with whom Chile had signed double taxation agreements, such as Peru.

| |  |  | Starting 2015 tax losses can be offset to the CREE taxable amount.
| | - |  | ------------------------------------------------------------------



| |  |  | The tax on wealth levies the wealth owned by an individual or legal entity that are income taxpayers; this is determined on the basis of the gross equity less current debts that are equal to or higher than a
1,000 million Colombian pesos (S/1.1 million approximately) at January 01, 2015.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The tax on wealth rates are marginal and cascaded in ranges of taxable base ranging from 0.2% to 1.15% in 2015, from 0.15% to 1% in 2016 and from 0.05% to 0.4% in 2017.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In December 2016 Law No.1819 was published with another amendment to the tax laws, effective from fiscal 2017. Major changes are as follows:



| |  |  | Income tax rates effective until 2016 (Income tax + CREE+ Overrate + Wealth) are now simplified with one single rate, i.e. 34% income tax rate and a temporary overrate of 6% for fiscal 2017 and an income tax rate of 33%
and a temporary overrate of 4% for fiscal 2018 and onwards on a taxable income of above S/895 thousand (equivalent to COP800 million).
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Colombian taxable income, applicable when there are tax losses, will be subject to a tax base of 4% of the liquid equity (formerly 3%) and will be considered as a
on-account payment of the taxable income.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Tax losses can be offset in the following eight (8) years from the date they were generated.

Under Chilean Legislation, when a Company reports tax losses, it can apply for a refund of
first-category taxes paid in prior years up to an amount that equals the taxes that would be levied on the tax losses, provided that no dividends have been distributed on the income obtained from the refund. The amount to be refunded by the Chilean
Tax Authorities is called provisional payment on absorbed profits - PPUA. The Company recognizes income from income tax and an account receivable when applying for this tax refund.

In 2016 the PPUA-derived income is related to the tax losses reported by of subsidiary VyV-DSD. In 2015
this item was related to the tax losses reported by CAM Chile Spa and VyV-DSD, amounting to S/19.4 million and S/21.9 million, respectively.

| | g) | The theoretical tax disclosed resulted from applying the income tax rate stipulated in the tax laws of the country in which a Group company is legally resident. Accordingly, for fiscal 2016, companies that are legally
resident in Peru, Chile and Colombia applied income tax rates of 28%, 24% and 40% respectively (28%, 22.5% and 39% for 2015; 28%, 21% and 34% for 2014). Norvial, GyM Ferrovías, Vesur and GMP (Blocks III and IV) have legal stability agreements
with Peruvian Government, in force for all years preserved. In this sense, the consolidated theoretical amount is obtained as a weighted average pre-tax profit or loss and the applicable income tax rate.

| | h) | Peruvian tax authorities have the right to examine, and, if necessary, amend the income tax determined by the Company in the last four years - from January 1 of the year after the date when the tax returns are
filed (years subject to examination). Therefore, years 2012 through 2016 are subject to examination by the tax authorities. Since differences may arise over the interpretation by the tax authorities of the regulations applicable to the Company, it
is not possible at present to estimate if any additional tax liabilities will arise as a result of any eventual examinations. Any additional tax, fines and interest, if they occur, will be recognized in the results of the period when such
differences with the tax authorities are resolved. Management considers that no significant liabilities will arise as a result of these possible tax examinations. Additionally, income tax returns for fiscal years 2013 to 2014 and those to be filed
for fiscal year 2016 remain open for examination by the Chilean tax authorities who have the right to carry out said examination within the three years following the date the income tax returns have been filed. Fiscal years 2014 and 2015 are open
for tax audit by Colombian tax authorities; fiscal 2016 will also be open for audit. Colombian tax authorities are entitled to audit two consecutive years following the date the income tax returns were filed.

| | a) | Tax contingencies -
| | -- | -------------------



| |  |  | For fiscal 2016 an appeal is in progress with the Peruvian Tax Court and another administrative action with the Judiciary involving the results of tax audits of VAT (IGV) and Income Tax returns performed by the Peruvian
tax authorities for fiscal years 1999 to 2002. The maximum exposure amount is S/5.2 million.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | With respect to our subsidiary GyM S.A., as a result of the tax audits of fiscal 1999, 2001 and 2010, SUNAT issued tax determination and tax penalties resolutions amounting to approximately S/19.1 million
(S/24.5 million as of December 31, 2015):
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In fiscal year 2017, the tax litigation process related to 2001 was
resolved, where the Tax Court orders SUNAT to recalculate the observations, determining an amount lower than initially claimed. Our subsidiary has decided to accept the conclusions of this resolution and submit fractionation requests for the payment
of the debt in reference amounting to S/14.1 million

Likewise, at the end of fiscal year 2017, the contentious-administrative
process related to the 1999 fiscal year was resolved, where the Judicial Branch rejected our arguments and confirmed what was stated by SUNAT. Regarding this process, there was already a contingency provision of S/5 million.

An administrative tax process related to the 2010 fiscal year is still underway, however, its resolution will not imply economic damage since
it corresponds to a greater refund of the balance in favor in 2011, already audited by the Tax Administration



| |  |  | Consortiums in which subsidiary GyM S.A takes part, brought claims with SUNAT against the results of the tax inspection, which had a maximum exposure at December 31, 2016 of S/2.8 million (S/0.8 million
at December 31, 2015).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | GMD and its subsidiaries have tax claims currently in progress involving fiscal years 2002, 2011 and 2012 with a maximum exposure of S/2.7 million at December 31, 2016.

| | iv) | Labor lawsuits for a total S/6.12 million (S/5 million comprising actions brought against GyM, S/0.35 million against STRACON GyM; S/0.65 million against GMP, S/0.2 million against GMD S.A., and
the remaining balance of S/0.1 million comprising actions brought against Concar, CAM Colombia and CAM Perú S.A.).

| | v) | Two securities class action have been filed against the Company, an executive and a former executive officers in the Eastern District of New York during the first quarter of 2017. Both complaints allege false and
misleading statements during the class period. In particular, they allege that the Company failed to disclose, among other things, that a) the company knew that its partner Odebrecht was engaged in illegal activities, and b) the Company profited
from such activities in violation of its own corporate governance standards. All parties have agreed to unify the two lawsuits and appoint a single lead plaintiff, with one single council to control the class action. On March 6, 2018, the court
appointed Treasure Finance Holding Corp. as the plaintiffs representative. In addition, the court has established the following schedule: i) on May 4, 2018, consolidation of files; ii) on July 3, 2018, presentation of the request for
dismissal; iii) September 4, 2018, presentation of the opposition to the request for dismissal; and iv) October 3, 2018, submission of allegations by GyM. After this, the court could dismiss the claim or admit it. Management believe that
both of those actions would likely be dismissed by the court for failure to adequately file a claim. Therefore, at the reporting date, we consider the risk of a material loss to the company is not probable.

| | vi) | On March 30, 2017, the minority interest holders of Adexus (Sistemas y Redes S.A. and Asesorías e Inversiones Busso Ltda.) filed three lawsuits against Graña y Montero S.A.A., GMD, Adexus and their
major executives, related to: a) the unenforceability of the Investment Agreement and Shareholders Agreement under the provisions of Law 18.046 (Ley de Sociedades Anónimas in Chile), for a total amount claimed of
US$11.4 million (equivalent to S/38.3 million); b) the declaration of nullity because of fraud of the Investment Agreement and other acts and damages and the order of forced execution of the Investment Agreement, plus damages for a total amount
claimed of US$50 million (equivalent to S/168 million); c) the declaration of nullity of the Shareholders Agreement and its amendments. The parties have responded and counterclaimed and up to date we are waiting for the date of the
Conciliation Hearing. The probability of loss of the present litigations is classified as remote.

|-- | ---------------------



| | a) | Acquisiton of Adexus S.A. -
| | -- | ---------------------------

In June 2015 the Company acquired 44% interest in the capital
stock of Chilean entity Adexus S.A., which is mainly engaged in providing IT solutions services. At December 31, 2015 the Company arrived at the conclusion that joint control existed and that the joint arrangement qualified as a joint venture;
therefore, the investment was recorded under the equity method of accounting in the consolidated financial statements of the Group (Note 16-b).

In January 2016 the Group acquired an additional interest of 8%, totaling 52% of total interest; the consideration agreed totaled
S/8.3 million which was settled through debt capitalization. This larger interest did not affected the investment classification as a joint venture.

Subsequently, in August 2016, the Group acquired an additional interest of 39.03% to obtain total interest in its capital stock of 91.03%; thus
gaining control over this entity. The consideration agreed totaled S/14 million which was initially stated as debt and then capitalized in the same period.

Losses arising from the re-measurement at fair value of the previously
held interest amounted to S/6.8 million, which was recognized in the statement of income within Other income and expenses, net, at the date of acquisition of that additional interest (Note 29).

Acquisition transaction costs amounting to S/1.4 million were charged to profit or loss within administrative expenses.

Revenue and net losses obtained for the period from the acquisition date to December 31, 2016 were S/113.2 million and
S/3.7 million, respectively. If Adexus had been consolidated from January 1, 2016, the balances of revenue and net losses would have been S/272.7 million and S/20.2 million, respectively.

Provided that the distribution of the consideration is divided between the fair values on a
provisional basis for the 2016 financial statements, the Group will complete the distribution process over a period that should not exceed one year as of the acquisition date of Adexus.

During such review period, additional assets and liabilities will be recognized as they may arise from updated data that may be obtained in
relation with the information that existed at the acquisition date and that does not comprise new incidents occurred after the acquisition date; that is, if the Group were to adjust initial amounts recognized at the business combination dates.



| | b) | Acquisition of Morelco S.A.S. -
| | -- | -------------------------------

In December 23, 2014, through subsidiary GyM S.A. the
Company obtained control of Morelco S.A.S. (Morelco) by acquiring 70.00% of its capital shares. Morelco is an entity domiciled in Colombia that is mainly engaged in providing construction and assembly services. This acquisition is part of the
Groups plan to increase its presence in markets that present high growth potential as in Colombia, and in attractive industries, such as mining and energy.

At December 31, 2014 the Company determined goodwill resulting from this acquisition on the basis of an estimated purchase price of
US$93.7 million (equivalent to S/277.1 million), which included cash payments made for US$78.5 million and cash payable estimated to be US$15.1 million (equivalent to S/45.7 million), which, under the agreement of the parties, would
be defined after a review of the acquirees balance sheet, mainly working capital, cash and financial debt as well as the final carrying amount of the acquirees work backlog. The estimated purchase price was allocated to the provisional
carrying amounts of the assets acquired and the liabilities assumed.

As a result of this allocation, the balance of goodwill was
determined to be US$36.1 million (equivalent to S/105.8 million).

In 2015 as part of the review of the provisional allocation of the
purchase price, the following situations arose:



| | a) | The balance at December 31, 2014 of the consideration payable of US$15 million (equivalent to S/46 million) was adjusted in 2015 to US$9.1 million (S/32 million) as a result of the final determination of
the working capital, cash and financial debt balances, under the purchase agreement. This amount was fully paid in 2015.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b) | The provisional fair values of certain assets acquired and liabilities assumed were reviewed.
| | -- | ---------------------------------------------------------------------------------------------

As a result of the above, the purchase price was adjusted to US $87.5 million (equivalent to S/258.6 million); the provisional fair values
of certain asset and liabilities were modified, giving rise to an adjustment of goodwill to US$35.2 million (equivalent to S/103 million).

The table below summarizes the consideration paid by Morelco and the determination of the fair value of the assets acquired and liabilities
assumed as well as a non-controlling interest at the date of acquisition:

Acquisition-related costs of S/4.5 million have been recognized to 2014s profits within
administrative expenses.

If Morelco had been consolidated from January 1, 2014 revenue and profit would have been
S/722.57 million and S/80.8 million, respectively.

Put and call options of
non-controlling interest-

Under the shareholder agreement signed for the acquisition of
Morelco, the subsidiary GyM signed a purchase-sale agreement for 30% of Morelcos capital stock held by the non-controlling shareholders. By this agreement, the
non-controlling shareholders obtained a right to sell their shares over a period and for an amount set in the agreement (put option). The period to exercise the option began on the second anniversary of the
acquisition of the option and expires on its tenth anniversary. The option exercise price is based on a EBITDA multiple less the net debt and until months 51 and 63 until from the date of the agreement a minimum amount is set that is based on the
price per share that GyM paid to buy 70% of Morelcos share capital.

On the other hand, the subsidiary GyM obtains call option to buy
those shares over a period of 10 years and at a price that is determined the same way as the put option price is determined, except for the fact the minimum amount is effective for the entire effective period of the option (call option).

Under the IFRS framework, the put option is for the Company an obligation to purchase non-controlling
interest shares, and therefore, the Group recognizes a liability measured on the basis of the present value of that option. Since the Group arrived at the conclusion that as a result of this agreement, it did not obtained the risks and rewards
inherent to the ownership of this share package underlying the option, initial recognition of this liability was a charge to equity of controlling shareholders within other reserves.

The amount of the liability arising from the put option was estimated at the present value of the redemption amounts expected on the basis of
minimum amount of the Morelcos agreement and the exercise rights of the option. The Company expects that purchase options are to be exercised at the date following the date of transfer. The expected redemption of the non-controlling interest is as follows: 41.66% in the second year, 41.66% in the fourth year and the remaining shares will be sold on the fifth anniversary of the option grant date. The discount rate used to
determine the present value of the expected redemption amounts is a risk-free rate available to comparable market participants and indicates the fact that the Group estimates to pay the minimum price of the agreement. At December 31, 2016 the
liability is estimated to be S/109.9 million, using a 0.78% discount rate for the first year, 1.37% discount rate for the third year and 1.76% for the fourth year (at December 31, 2015 it was S/113.5 million, using a 0.65% discount
rate for the first year, 1.31% discount rate for the third year

and 1.76% for the fourth year). In 2016 the changes in the present value of the put option
estimated to be S/0.7 million were recognized in the statement of income (an expense by S/1 million stated within Other income and expenses, net and an income by S/1.7 million stated within Exchange losses,
net, Note 28).



| | c) | Acquisition of Coasin Instalaciones Ltda.
| | -- | -----------------------------------------

In March 2014, through the subsidiary CAM Chile
S.A., the Group acquired control of Coasin Instalaciones Limited with the purchase of 100% of its capital shares. Coasin is an entity incorporated in Chile and is mainly engaged in providing installation and maintenance services for networks and
equipment related to the telecommunications industry.

This acquisition is part of the Groups plan to increase its market share
considering the significant growth potential in Chile, and in other attractive industries, such as utilities.

During a period of twelve
months after the date of acquisition, the Group reviewed the allocation of the purchase price for the acquisition of Coasin Instalaciones Limitada.

Over a period of twelve months after the acquisition, the Group reviewed the allocation of the purchase price and fair values determined
provisionally for certain assets and liabilities. As a result of this process, the balance of goodwill was changed to US$2.2 million (equivalent to S/6.4 million).

|35 | EARNINGS (LOSSES) PER SHARE
|-- | ---------------------------

Basic earnings per share are calculated by dividing the net
profit of the period attributable to common shareholders of the Group by the weighted average number of common shares outstanding during the year. No diluted earnings per common share were calculated because there are no common or investment shares
with potential dilutive effects (i.e., financial instruments or agreements that give the right to obtain common or investment shares); therefore, it is equal to basic earnings per share.

The basic earnings per share are broken down as follows:

|37 | EVENTS AFTER THE DATE OF THE STATEMENT OF FINANCIAL POSITION
|-- | ------------------------------------------------------------



| | a) | Early termination of the GSPs concession agreement -
| | -- | -----------------------------------------------------

According to a notification
issued by the Ministry of Energy and Mines of Peru on January 24, 2017, the early termination of the Concession Contract was declared, based on the provisions of clause 6.7 of the Concession Agreement Improvements to the countrys
energy security and development of the South Peru Gas Pipeline , as GSP failed to certify the financial closing within the established contractual deadline and proceeded to the immediate execution of the performance guarantee. This situation
generated the execution of the counter-guarantees offered by the Group to the company issuing the performance guarantee of the Concession Contract for US $ 52.5 million (S /. 176.6 million) and US $ 129 million (S / 433.3 million). for the
corporate guarantee of the bridge loan granted to GSP.

On October 11, 2017, the agreement was signed for the delivery of the goods of
the Southern Peru Gas Pipeline concession between GSP and the Ministry of Energy and Mines (MEM). As stated in the agreement, GSP delivered most of the Concession Assets in possession to the administrator designated by the MEM for its custody and
conservation. The assets include all the works, equipment and facilities provided for the execution of the project, as well as the engineering studies that were prepared by the concessionaire company.

After the termination of the contract, the Peruvian Government, in accordance with the contract, had to hire an audit entity of recognized
international prestige to calculate the Net Book Value (VCN for its Spanish definition Valor Contable Neto) of the Concession Assets and the subsequent call for up to three public auctions, being the base amount for the first
of them 100% of the VCN, guaranteeing in any case that after the third auction, in case the concession has not been awarded, the payment to GSP would be at least 72.25% of the VCN. Having elapsed more than a year since the termination of the
contract, the Peruvian Government has not taken any action to calculate the VCN and call for auctions. In the opinion of the external and internal legal advisors, since the previous procedure had not been done within the established deadlines, the
Peruvian Government would be obliged to pay GSP 100% of the VCN. Regarding the amount of the VCN there is a previous calculation commissioned by GSP reviewed by an audit firm as an independent expert as of December 31, 2016, which determined a
VCN of US $ 2,602 million.

GSP as of December 4, 2017 entered into a bankruptcy proceeding that will be carried out by
the National Institute for the Defense of Competition and Intellectual Protection of Peru (hereinafter, INDECOPI), and the Group registered a claim for accounts receivable in 2017 charge for US $ 434,465.77 and the fiduciary based in its capacity as
administrator accounts receivable amounting US $ 169,287,006

(All amounts expressed in thousands of S/ unless otherwise stated)



Based on the amount of the VCN, applying the payments foreseen in the insolvency proceedings,
the subordination contracts and the loan cession agreements between the Group and GSP partners, the assumption that an international arbitration will be required to achieve the payment by the Government, and, in accordance with the conclusions of
the internal and external legal advisors, it is estimated that the international arbitration would take approximately 5 years to resolve. This is why an impairment of the investment was recorded, which includes a finance update and estimation of
costs for US $ 202.3 million before taxes at the income statement, as indicated in notes 13. c) and 16.

In addition, considering the
early termination of the GSP contract, the Group evaluated the impairment of the financial statements of CCDS. As a result, a net loss before taxes of S / 15.2 million was determined (Note 5.1-f), that
was recognized in gross profit in the Engineering and Construction segment.

Same as in the Emergency Decree 003, Law 30737 (see note 1 c)
iii) in its First Section, includes Odebrecht and its related companies, which include GSP. According to this Law, GSP will not be able to make transfers abroad, will require the consent of the Ministry of Justice in case it wishes to sell assets
and must deposit the proceeds of such sale in a guarantee trust. Likewise, the entities of the Government that must make some payment to the entities included in the Law, must withheld according to the contract 10%, equivalent to the net profit
margin, and deposit it in the aforementioned trust in guarantee. According to our internal and external legal advisors, Government payment for the VCN is not within the scope of the withholding, as this payment does not include net profit margin,
nor is a sale of assets.



| | b) | Renegotiations of liabilities and credit lines -
| | -- | ------------------------------------------------



| | i) | Credit Suisse Syndicated Loan
| | -- | -----------------------------

On June 27, 2017, the Company renegotiated the terms of
this loan to clear breaches related to the termination of the GSP concession. The new terms establish repayment by December, 2020. See Note 19-i)



| | ii) | GSP Performance Guarantee
| | --- | -------------------------

On March 31, 2017, the Company renegotiated the terms for
repayment obligations regarding the proportional share of the performance guarantee issued in connection with the GSP concession (Note 22). The new terms require repayment by June 30, 2018, with interest accrual 6% per year, and provide a
security interest over our shares in CAM, and lien on certain assets cash flows.

Oil and Gas Producing Activities

In
accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 932, Extractive Activities-Oil and Gas, and regulations of the U.S. Securities and Exchange
Commission (SEC), the company has included certain supplemental disclosures about its oil and gas exploration and production operations.

All information in the following supplemental disclosures related to Blocks I, III, IV and V. Information with respect to Blocks III and IV
has been included from April 5, 2015, when the company began operating these blocks.



|A. | Reserve Quantity Information
|-- | ----------------------------

Graña y Montero Petrolera S.A. net proved reserves
in the fields in which they operate and changes in those reserves for operations are disclosed below. The net proved reserves represent the companys best estimate of proved oil and natural gas reserves. For 2015 and 2016 reserve estimates have
been evaluated by its technical staff (reservoir engineers and geoscience professionals) and submitted to its Reserve Development Committee. The estimates for all years presented conform to the definitions found in FASB ASC paragraph 932-10-65-1 and Rule 4-10(a) of Regulation S-X.

Proved oil reserves are those quantities of oil, which, by analysis of geosciences and engineering data, can be estimated with reasonable
certainty to be economically producible, based on prices used to estimate reserves, from a given date forward from known reservoirs, and under existing economic conditions, operating methods, and government regulation prior to the time at which
contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain.

The term reasonable
certainty implies a high degree of confidence that the quantities of oil actually recovered will equal or exceed the estimate. To achieve reasonable certainty, the companys engineers and independent petroleum consultants relied on
technologies that have been demonstrated to yield results with consistency and repeatability. The technologies and economic data used to estimate the companys proved reserves include, but are not limited to, well logs, geologic maps, seismic
data, well test data, production data, historical price and cost information and property ownership interests.

|(1) | Proved reserves estimated in oil and gas properties located in Blocks I, III, IV and V (Talara and Paita) under two service contracts and two license contracts with Perupetro. The rights to produce hydrocarbons expire
in December 2021 for Block I, April 2045 for Blocks III and IV, and October 2023 for Block V. The proved reserves estimated in this report constitute all of the proved reserves under contracts by Graña y Montero Petrolera S.A.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(2) | The revisions in reserve estimates are based on new information obtained as a result of drilling activities and workovers. During 2016, proved developed reserves of crude oil increased due to drilling activities in
Block IV and the impact of the higher price in reserve estimations. In 2015, natural gas proved reserves decreased as a result of reviews of Block I oil reserves.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(3) | As of December 31, 2015, the associated gas reserves were 50,103 MMCF and included gas reserves of the Blocks I, III and IV. As of December 31, 2016, associated gas reserves decreased to 10,521 MFCF because
the associated gas reserves of the Blocks III and IV had been re-categorized as resources, due, mainly, to the low certainty that such reserves would be economically producible in the future under existing
commercial conditions, operating methods and regulations. This reduction in gas reserves did not have an impact on the companys financial statements after the results obtained from the impairment tests of the mentioned assets.

|E. | Standardized Measure of Discounted Future Net Cash Flows
|-- | --------------------------------------------------------

The standardized measure of
discounted future net cash flows, related to the proved reserves is based on estimates of net proved reserves and the period during which they are expected to be produced. Future cash inflows are computed by applying the 12 month period unweighted
arithmetic average of the price as of the first day of each month within that 12 month period, unless prices are defined by contractual arrangements, after royalty share of estimated annual future production from proved oil and gas reserves.

Future production and development costs to be incurred in producing and further developing the proved reserves are based on year end cost
indicators. Future income taxes are computed by applying year end statutory tax rates.
