Financial Information

Our consolidated financial statements included in this annual report have been prepared in nuevos 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, 2013, 2014 and 2015 have been audited by
Gaveglio, Aparicio y Asociados S.C. de R.L., a member firm of PricewaterhouseCoopers in accordance with the standards of the Public Company Accounting Oversight Board (United States).

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 6 to our audited annual consolidated financial statements.

In this annual report, we present Adjusted 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 Adjusted 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. Our management uses Adjusted EBITDA, among other measures, for internal planning and performance
measurement purposes. Adjusted 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). Adjusted EBITDA, as calculated by us, may not be comparable to similarly titled measures reported by other companies. For our definition of Adjusted EBITDA and a reconciliation of Adjusted
EBITDA to the most directly comparable IFRS financial measure, see Item 3.A. Key InformationSelected Financial DataNon-GAAP Financial Measure and Reconciliation.

We have translated some of the nuevos soles amounts contained in this annual report into U.S. dollars for convenience purposes only. Unless
otherwise indicated or the context otherwise requires, the rate used to translate nuevos soles amounts to U.S. dollars was S/.3.413 to US$1.00, which was the exchange rate reported for December

##### Table of Contents

31, 2015 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 nuevos 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 nuevos 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 nuevos 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 nuevos 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 nuevos soles to U.S. dollars.

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.

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 is jointly
controlled. 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,

Non-GAAP Financial Measure and
Reconciliation

In this annual report, we present Adjusted 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 Adjusted EBITDA as net profit
plus: financial (expense) income, net; income tax; depreciation and amortization; and certain other adjustments described below.

Our
Adjusted EBITDA includes the following other adjustments: (i) in our Infrastructure segment, in Mass Transit, we add back to net profit the components of our tariff for the Lima Metro that relate to the Peruvian governments repayment of
the amounts we invest to purchase trains and other infrastructure, since we do not amortize these investments, and the interest we charge the Peruvian government in connection with the amounts we invest for such purposes. For a description of the
components of our tariff for the Lima Metro, see Item 5.A. Operating and Financial Review and ProspectsOperating ResultsFactors Affecting our Results of

OperationsInfrastructure; and (ii) in our Real Estate segment, we add back to net profit the portion of our costs of sales related to our cost to purchase land, as we recognize
land purchases as inventory and, accordingly, do not mark-to-market or depreciate the value of our land.

We present Adjusted 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. Our management uses Adjusted EBITDA, among other measures,
for internal planning and performance measurement purposes. Adjusted 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). Adjusted 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 Adjusted EBITDA on a consolidated basis.

Exchange Rates

The Peruvian nuevo 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.

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. 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 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 may not be able to continue the historic growth of our business

We have experienced rapid growth in our operations in recent years and our strategy is to continue to grow our operations, including through
international expansion. However, our growth rate has slowed recently and we may not be able to continue to grow our business at the same pace as in recent years, or at all. Our organic revenues (i.e., excluding the results of all acquisitions since
2011) grew at a CAGR of 13.2% from 2011 to 2015 (under IFRS). Our organic revenues grew 5.4% in 2015 from 2014. The pace at which we are able to grow our business could be adversely affected by numerous factors, some of which are beyond our control,
including, among others, the slowdown in Perus recent rapid economic growth and the postponement in investment in infrastructure, as well as increased competition and our capacity to increase scale and manage growth in our company.

Growth can place significant demands on our management and operating structure, and too rapid growth may overwhelm our operating capacity. In
addition, sustained growth will require us to recruit a large number of talented professionals and we cannot assure you that we will be able to hire sufficient engineers or other personnel with the expertise and experience we require. Nor can we
assure you that as our company continues to grow we will be able to maintain our performance standards and corporate values across our entire organization. Failure to manage our growth effectively could adversely affect the quality of our products
and services, which would have a material adverse effect on our business.

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 regulation, 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. The second round of presidential elections in Peru between Keiko Fujimori and Pedro Pablo Kuczynski is scheduled to take place on June 5, 2016. We cannot assure you who
will be elected the new President of Peru, nor can we assure you the newly elected administration will maintain current government policies.

Social
conflicts may disrupt infrastructure projects

Despite Perus ongoing economic growth and stabilization, high levels of
poverty and unemployment and

##### Table of Contents

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.

We may not be able to successfully expand outside of Peru

One of our key strategies is to continue to expand our operations outside of Peru, particularly in Chile and Colombia, and we expect that our
international operations will 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 strategy is 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.

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 nuevos soles or other local currencies. As a result, any depreciation of local currency would diminish the amount of revenues eventually earned relative to backlog. Moreover,
as of December 31, 2015, one client, Ecopetrol, concentrated 84.1% of Morelcos backlog, and another client, Rio Alto, concentrated 58.7% of Stracons backlog. Additionally, as of such date, a 29% participation in the construction
consortium of the Gasoducto del Sur Peruano project, constituted 25.3% of our backlog as of December 31, 2015. Finally, 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 not grow at recent historic rates and may decline. We cannot assure you that we will be able to
continue obtaining sufficient contracts in the future in number and magnitude to continue 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.

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 2016 and 2017 to backlog as of December 31, 2015 that is currently expected to be realized in each of those years 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 (including, among others, our Chairman and our Chief Executive Officer). 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. The loss of the services of some of our senior
management or members of our board of directors could have a material adverse effect on our business and financial performance. 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.

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, and 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 of these inputs



25



---

##### Table of Contents

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 recently, but we cannot assure you that oil prices will not 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 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 has
begun to increase target interest rates in the United States. Most emerging economies 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 once we have won awards in arbitration proceedings, particularly claims
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 joint operations 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 joint operation 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 joint operations or other strategic alliances, our ability to compete for new business may be adversely affected.

##### Table of Contents

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

Joint operations 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 joint operations 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 joint operation 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 joint operation 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 joint
operation or other strategic alliances.

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

We rely on third-party suppliers to provide much 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 instance of the judicial proceeding we had initiated to contest such administrative proceeding. We
appealed the adverse judgment and are currently in



27



---

##### Table of Contents

appeal 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. Furthermore, in March 2014, the regional government of Cusco provided us with a notice that they had terminated one of Concars toll road operation and maintenance
contracts, representing a backlog loss of US$48.4 million. We believe this termination is invalid, since we had previously terminated the contract due to a lack of payment and failure to provide access to the related road. All of these procedures
remain pending as of the date of this annual report. A significant part of our revenues on a consolidated basis is derived from public sector contracts in Peru. 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.

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 against financial market risks

Our operations are exposed to financial market risks, such as risks related to exchange rates, commodity



28



---

##### Table of Contents

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 realize 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 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



29



---

##### Table of Contents

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 we have in the past 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 biding for a project or concession, the government may subsequently declare the process void for political,
budgetary or other reasons and may withdraw 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 sixteen 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.

We have made significant investments in the Gasoducto Sur Peruano project and we cannot assure you that the project will be completed as expected

We have made significant investments in the Gasoducto Sur Peruano project and we cannot assure you that the project will be
completed as expected. In September 29, 2015 we acquired a 20% stake in Concesionaria Gasoducto Sur Peruano S.A. which represented an investment commitment of US$215 million. The other participants in this concessionaire are Odebrecht Latinvest
with a 55% stake and Enagas with a 25% stake. Along with this acquisition we also acquired, via our E&C segment, a 29% participation in the construction consortium of the Gasoducto del Sur Peruano project which added an approximate US$ 1.0
billion to our backlog. Although we have invested and committed substantial amounts into this project, as we hold a minority position in the consortium, we cannot control the timings and deadlines of the project or the expenses incurred in its
development or construction. Moreover, the Gasoducto Sur Peruano project may face financing challenges due to the recent criminal conviction by Brazilian courts of the ex-president and other former key executives of Odebrecht S.A., for charges of
corruption, money laundering and criminal organization. Reputational concerns derived from such convictions and investigations could affect the availability of, or increase the cost of, financing for the Gasoducto Sur Peruano project.

Our reputation could be affected by our past and current consortia with Odebrechts affiliates in Peru.

We have participated in the past, and are currently participating, in consortia controlled and operated by Odebrecht affiliates in Peru. Our
reputation may be affected due to the recent criminal convictions by Brazilian courts of the ex-president and other former executives of Odebrecht S.A. for charges of corruption, money laundering and criminal organization. In addition, according to
news reports, the Peruvian congress has initiated an investigation into the dealings of Odebrechts affiliates in Peru. We cannot assure you that these investigations will not be broadened to include other entities relating to Odebrechts
consortia in the country, including, among others, our subsidiary GyM. Although we have not received any notification of this investigation, news report indicate that the investigation includes the concessions for Interoceanica Norte and
Interoceanica Sur highways, in which our subsidiary GyM held a minority non-operating participation in consortia led by Odebrecht affiliates from 2005 to 2011, when we sold our stakes. We cannot assure you that our reputation will not be affected by
our consortia with Odebrecht.

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 recent decline in prices for minerals or oil and gas
(including the recent steep decline in global oil and gas prices) 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. Such declines
in investment have particularly affected our subsidiary Vial y Vives. 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.

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



31

##### Table of Contents

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 months, with the average Brent crude prices declining from US$111.65 in 2012, US$108.64 in 2013 and
US$99.02 in 2014 to US$ 50.85 per barrel in 2015 and US$ 43.19 per barrel on April 21, 2016. 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, 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 revoke the agreement for certain reasons set forth in the relevant documentation contract and in 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



33



---

##### Table of Contents

may terminate and/or repossess a concession at any time, if, in accordance with applicable law, it 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. Moreover, 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. 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 2017, with a new public biding expected to take place at the end of 2016 or the beginning of 2017. 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, in particular the concession for the Via Expresa Javier Prado. A contract for the Via Expresa Javier Prado 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 related to traffic volumes prior to approving the project. Such studies are currently being prepared. We cannot assure you that the Ministry will approve the contract under the current terms or
at all. We may not be able to negotiate contracts terms that are favorable to us or at all. In addition, these projects may suffer long delays or suspension as a result of political considerations or other factors.

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



34

##### Table of Contents

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. 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 16 real estate projects in various stages of development. We have not yet initiated the administrative processes before the appropriate authorities, or such procedures are pending approval,
for two of these developments, including our Project Espacio (formerly Cuartel San Martín), a multi-use development project, as they are still in the early stages of development. A denial or an extended delay by applicable administrative
authorities may render land unsuitable for development or 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 2015, approximately
98% 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.



35

##### 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 that in effect altered their contractual arrangements with purchasers, including one determination against Viva GyM which we are currently challenging in the judicial system. Moreover, some purchasers of our real estate have recently
filed complaints against us before INDECOPI and/or made claims in the media with the objective of obtaining not only compensation for alleged deficiencies in housing construction but also improved terms from those that they originally agreed to,
which may have a negative impact on our real estate business. An increase in consumer complaints and consumer protective measures, particularly those that alter contractual terms, if we are not able to counter these claims, may affect our ability to
enforce our contracts under existing terms, which 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, 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.

##### Table of Contents

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 service contracts if the government decides not to award additional public-sector road contracts or, to a lesser extent, 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.

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 business-friendly and open-market policies that stimulate economic growth and
social stability.

Political developments in Peru following the presidential election could adversely affect the Peruvian
economy

The second round of presidential elections in Peru between Keiko Fujimori and Pedro Pablo Kuczynski is scheduled to take
place on June 5, 2016. We cannot assure you who will be elected the new President of Peru. Nor can we assure you that the newly elected administration will maintain current government policies. Each of the presidential candidates have announced
significant economic and policy reforms. The impact that these measures and any future measures taken by the newly elected administration will have on the Peruvian economy cannot be predicted. Political uncertainty in Peru relating to the measures
to be taken by the new administration in respect of the Peruvian economy could lead to volatility in the market prices of securities of Peruvian companies, including ours.

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

Fluctuations in the value of the nuevo sol relative to the U.S. dollar could adversely affect Perus economy. In addition, fluctuations
in the value of the nuevo sol to the U.S. dollar can materially adversely affect our results of operations. In 2015, 56.8% and 43.2% of our revenues were denominated in nuevos soles and U.S. dollars, respectively, whereas 72.7% and 27.3% of our
costs of sales were denominated in nuevos soles and U.S. dollars, respectively. In the past the exchange rate between the nuevo sol and the U.S. dollar has fluctuated significantly. We cannot assure you that the value of nuevo 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.

In addition, although Peruvian law currently imposes no restrictions on the ability to convert nuevos 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 4.7% in 2011, 2.6% in 2012, 2.9% in 2013, 3.2% in 2014 and 4.4% in 2015, 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



38

##### Table of Contents

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 that 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 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, 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 may reduce the confidence of
foreign investors, causing volatility in the securities markets and affecting the ability of companies to obtain financing globally. 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

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 directors and senior management, directly and indirectly, own approximately 32.28% of our common shares as of December 31, 2015, and
our Chairman owns, directly and indirectly, 17.81% of our common shares. 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 twenty-five
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 attribute 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
nuevos 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

##### Table of Contents

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.

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 evaluation of our internal control over financial reporting as of December 31, 2015, our Chief Executive Officer and Chief
Financial Officer concluded that, as of such date, our internal control over financial reporting was not effective at the reasonable assurance level due to a control deficiency that constituted a material weakness, as a result of inadequate controls
over segregation of duties in certain activities within four of our subsidiaries, namely, Survial, GMP, GYM Ferrovias and Vial y Vives. In particular, certain persons at such subsidiaries had access to conduct conflicting accounting operations,
which would be against our accounting policies. The internal controls we had in place to detect these conflicts in our segregation of duties failed, because we failed to gather all of the applicable information, as a consequence of the process of
information gathering being conducted manually. 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 implementing certain measures to address this material weakness, such as the review of employee access to our accounting systems and the deployment of IT tools in order to
improve controls over segregation of duties, especially regarding activities that are conducted manually.

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 controls, 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 as required by Section 404 of the U.S. Sarbanes-Oxley Act of 2002, investors could lose confidence in the reliability of our consolidated financial statements, which could result in a
decrease in the value of our ADSs.

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



42

##### Table of Contents

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, our officers and directors or our 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 our 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 nuevos 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 nuevos soles. Under Peruvian exchange control limitations, an obligation in Peru to pay amounts denominated in a currency other than nuevos 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 2015, and the largest publicly-traded
engineering and construction company in Latin America as measured by market capitalization as of December 31, 2015, 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 3,600 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.

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, Colombia and Brazil. 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. We expect to continue to selectively undertake projects and pursue acquisitions and strategic alliances in Latin America to further
expand our company outside Peru, with a particular focus on Chile and Colombia.

The tables below show our backlog, revenues and Adjusted
EBITDA from 2011 to 2015.

Backlog (in millions of S/.)
                Revenues (in millions of S/.)         Adjusted EBITDA (in millions of S/.)



LOGO

During 2015, we generated revenues of S/.7,832.4 million (US$ 2,294.9 million), Adjusted EBITDA of S/.778.4
million (US$228.1 million), and net profit of S/.141.7 million (US$41.5 million) including net profit attributable to controlling interest of S/.88.2 million (US$25.8 million). From 2011 through 2015, our revenues and Adjusted EBITDA grew at a
compounded annual growth rate (CAGR) of 16.6% (12.6% excluding acquisitions) and of 4.1% (3.1% excluding acquisitions), respectively. From 2014 through 2015, our revenues grew 11.8% (3.1% excluding acquisitions) and our Adjusted EBITDA declined
14.6% (7.8% excluding acquisitions).

Our Strengths

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

Leader in fast-growing markets

We are the largest engineering and construction company in Peru as measured by revenues during 2015, and the largest publicly-traded
engineering and construction company in Latin America as measured by market capitalization as of December 31, 2015. Peru is undergoing a period of unparalleled development, with over 4.8% average annual real GDP growth between 2009 and 2015 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, the largest 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 top ten most admired companies in Peru through a survey conducted by PwC in 2012, 2013, 2014 and 2015. In addition, Merco ranked us seventh out of 100 companies with
the best reputations in Peru in 2012, 2013, 2014 and 2015. We believe that our track record and the reputation we have earned in our markets 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.

Growth and profitability with strong
financial position

Our operations have grown over the last several years, with our consolidated revenues and Adjusted EBITDA
growing at CAGR of 16.6% (12.6% excluding acquisitions) and 3.8% (3.1% excluding acquisitions) from 2011 to 2015, respectively. During 2015, we continued to grow in revenues but our adjusted EBITDA declined. We have achieved this growth with low
levels of indebtedness, relying mainly on cash flow from operations to fund our growth. As of December 31, 2015, our net debt to Adjusted EBITDA ratio was 2.6x, with net debt of S/.(2,021.4) million (US$(592.3) million). In 2015, we achieved an
Adjusted EBITDA margin (i.e., Adjusted EBITDA as a percentage of revenues) of 10.0%.

Robust backlog and significant additional potential projects

We have a robust backlog which amounted to US$4,486.0 million as of December 31, 2015. We believe that our backlog, which as
of December 31, 2015 represented approximately 2.0x our related 2015 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. Approximately, 80.7% of our backlog as of December 31, 2015 is comprised of contracts with the private sector, strategically targeted to our key end-markets, such as mining, infrastructure, power,
energy and real estate. In addition to our backlog, we also have significant potential projects in our pipeline. We have already been awarded a concession for the Via Expresa Javier Prado project, for which we are currently in the contract
negotiation stage. We are also in the process of obtaining the necessary licenses to begin construction of our Project Espacio (formerly Cuartel San Martín), a large multi-use real estate development. 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. In addition, on September 29, 2015 we acquired a 20% stake in Concesionaria Gasoducto Sur Peruano S.A. which represented an investment commitment of US$ 215 million. Along with
this acquisition we also acquired, via our E&C segment, a 29% participation in the construction consortium of the Gasoducto del Sur Peruano project, which represented 25.3% of our backlog as of December 31, 2015. 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 as we continue to expand our operations in Latin America.

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

Our senior management team has an average tenure within our company of approximately 20 years. Euromoney recognized us in March 2014 as the
best managed company in Latin America, the first time a Peruvian company has received this recognition, and in 2015 the best managed company in the construction and cement sectors in Latin America. For the third consecutive year, we were recognized
by PWC as one of the ten most admired companies in Peru, with an outstanding ranking in the corporate governance category. Also, we received an award from LatinFinance magazine for being the corporate with the best equity market strategy, as well as
the Andean corporate with the best capital markets strategy, as part of the 2014 LatinFinance Best Corporates survey. In addition, for the third year (2014, 2010, 2009) we were granted the Llave de la BVL award by the Lima Stock Exchange
for good corporate governance as well as for the liquidity of our shares. 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 3,600 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 been listed on the Lima Stock Exchange since 1997 and the New York Stock Exchange since 2013. We abide by the highest corporate
governance standards in Peru, and we are one of only 15 companies in Latin America, and one of only three in Peru, that form part of the Companys Circle, which recognizes companies for their high corporate governance standards and is sponsored
by the International Finance Corporation (IFC), the Organization for Economic Co-operation and Development (OECD) and the Global Corporate Governance Forum. In addition, we won the best corporate governance award in the South American construction
sector granted by the Ethical Boardroom Corporate Governance Awards; and we were named both a Leading Company in Sustainability and a Leading Company in Corporate Governance by Alas20, a Latin America-wide organization that evaluates and qualifies
sustainability and corporate governance matters in the region. In 2015, we came in tenth place in the ranking of most responsible companies and the ranking of the companies with best corporate governance, both by Merco Reputación, a Spanish
consulting company that prepares corporate governance rankings, and which processes are verified and audited by KPMG. We won the first place for social responsibility and sustainable development among companies in the Employees category, in the
Perú 2021 awards organized by Asociación Perú 2021, a Peruvian non profit which is a member of the World Business Council for Sustainable Development and PUCP (Pontificia Universidad Católica del Perú). In
addition, we were placed 9th in the ranking of the 100 best companies to work in Peru, according to the Merco People reputation monitor and we were named Best Managed Company in the Latin American Cement and Construction Sector by Euromoney.

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 2015, we had an accident incidence rate of 0.39, calculated over 127,379,277 hours worked.

Our Strategies

Our vision is to be the most reliable engineering services company in Latin America. Our key 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.

Further expand our infrastructure-related businesses to increase activity across our business segments and generate more stable cash flows

We plan to continue to expand our infrastructure-related businesses to capitalize on private and public investments in Peru, including in toll
roads, airports, ports, railroads, hospitals, water utility companies, and other power and oil and gas infrastructure assets. In addition to providing more recurring and predictable cash flows, our Infrastructure segment generates additional
business opportunities for our E&C and Technical Services segments.

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. We intend to remain financially disciplined by limiting substantially all our debt incurrence to identified projects with repayment sources.

Selectively pursue international opportunities, focusing on Chile and Colombia

We intend to leverage the capabilities and experience we have in Peru, particularly providing engineering and construction services to the
mining, oil and gas and infrastructure end-markets, to continue evaluating and selectively pursuing opportunities in other markets. We expect to focus our efforts primarily on Chile and Colombia, which we believe offer attractive opportunities in
these end-markets. We intend to evaluate other international opportunities on a case-by-case basis.

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. In 2012, the Inter-American Federation of the Construction Industry recognized us
for our corporate strategy and promotion of citizenship with the Latin American Social Responsibility award. In addition, in 2014, KPMG ranked us eleventh among the 100 most responsible companies and with the best corporate governance in Peru, and
the firm Merco, with the support of KPMG, placed us seventh in the ranking of the 100 Peruvian companies with the best reputation. In 2015 Alas20 named us Leading Company in Sustainability and Leading Company in Corporate Governance and Merco
Reputación ranked us tenth place in the 2015 ranking of most responsible companies and with best corporate governance. 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.

Engineering and Construction

Our E&C segment has a more than 80-year track record and is the largest player in Peru as measured by revenues during 2015, according to
our estimates based on Peru: The Top 10,000 Companies 2015, undertaking a

##### Table of Contents

broad range of activities relating to: engineering; civil construction; electromechanic construction; building construction; and contract mining. We provide E&C services for a diverse range
of end-markets, focusing on the mining, power, oil and gas, transportation, real estate and other infrastructure sectors. The following chart sets forth our 2015 revenues by end-market.

2015 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 2015,
approximately US$460 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$45 billion between 2015 and 2019, 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 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 Xstrata, Sociedad Minera Cerro Verde, Guyana Goldfields, Luz Del Sur, Kallpa Generación, Samsung Engineering, Rio Alto, Chinalco Mining, Hudbay Minerals, Red Eagle Mining Corporation, among others. We have a
well-diversified client base, as none of our engineering and construction clients accounted for 12% or more of our consolidated revenues in 2015.

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 95% of our 2015 revenues came from private-sector projects. 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 costs.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | 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.

Operations.

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.

##### Table of Contents

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 Besalco S.A., Odebrecht S.A., Andrade
Gutierrez S.A., Obrascón Huarte Lain S.A., JJC Contratistas Generales S.A., Cosapi S.A., Techint SAC, SSK Montajes e Instalaciones S.A.C., Skanska del Perú S.A., Mota-Engil Peru S.A., Grupo San Jose, Salfacorp S.A., Constructores
Interamericanos S.A.C. (COINSA), and San Martín Contratistas Generales. 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 ten multiple fuel storage facilities, four producing oil fields under long-term government contracts and we own a gas processing plant, and are
part of the consortium for the construction of the southern gas pipeline project.

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, 2015.

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 Enagas and CPPIB whereby we acquired 51% of Tecgas, the current operator of TGP and owner of 100%
of the shares of COGA, while Enagas 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 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. As of the date of this Annual Report, we have funded an approximate amount of US$183.2 million of the
total committed amount. The other participants in the consortium are Odebrecht Latinvest with a 55% stake and Enagas with a 25% stake. Concesionaria Gasoducto Sur Peruano S.A. is responsible for the design, construction and operation of the southern
gas pipeline, a project which will bring natural gas to the southern region of Peru, particularly to the provinces of Cuzco, Arequipa, Puno and Moquegua. The expected date of completion of the pipeline is during the first quarter of 2019. As we hold
a minority stake in Concesionaria Gasoducto Sur Peruano S.A., we do not include the results of this venture in our consolidated results under our Infrastructure segment.

Principal 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.

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.



LOGO

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 nuevo 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 in the third quarter of 2016.We estimate that our capital investment for the second stage
will be approximately US$100 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 2013, 2014 and 2015.

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 2013, 2014 and 2015 the fee amounted to US$20.7 million, US$8.9 million and US$33.9 million,
respectively. Our revenue in this concession does not depend on traffic volume. Additionally, we had a one-time income in 2013 for catastrophic events relating to heavy rains that impacted the highway in prior years, which amounted to US$15.8
million.

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 2013, 2014 and 2015, the fee amounted to US$1.8 million, US$1.4 million and US$1.3 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 Via 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 of approximately US$200 million. Such investment will be made during the construction phase, which is expected 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 guarantee a minimum annual revenue of US$18 million during the first two years of the concession term and US$19.6 million for the third year and for an additional period, the term of
which is being negotiated. 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. Completion of the project is
subject to expropriation of the land necessary for the construction of the road.

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. 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. Such studies are currently being prepared. We cannot assure you that
the Ministry will approve the contract under the current terms or at all.According to estimates from the Municipality of Lima, the total investment in the concession is expected to amount to approximately US$700 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. We cannot assure you if or when the concession contract 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 25th of 2014.

##### Table of Contents

The construction of the first and second stretches of Line One was carried out by our Engineering
and Construction 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.

LOGO

As of December 31, 2015, GyM Ferrovías had spent a total of S/.591.0 million (US$173.2 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 kms 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./78.34.

Pursuant to the concession, we must comply with certain
requirements in the operation of the trains. According to the concession, at least 95% of our trains must be running and available for use and not less than 85% of our trains that are available for use must arrive to destination on scheduled time.

Trujillo Urban Transportation

In October 2014, our subsidiary GMD S.A. was awarded a concession for the electronic collection of public transportation fares in the city of
Trujillo in northern Peru for a period of twenty 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. Nonetheless, we have committed to renew the equipment upon its wear down due to
common use. Such technological renovation is estimated at US$18 million, which will be paid over the following eight years. The contract was signed in April 2016.

Water Treatment

In 2012, 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 project and our partner
Acciona Agua holds the remaining 50%. The plant is expected to be operational in July 2016.

We estimate that La Chiras total
investment in the concession will amount to approximately US$83.1 million. Once the project is completed, La Chira will be entitled to collect (i) an annual payment for the investment

energy businesses within our Infrastructure segment. We operate and extract oil from four 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 onshore oil producing fields, Blocks I and V. We have two
long-term license contracts with Perupetro for the two other blocks, Block III and IV, which started operations in April 2015. Aggregate average production in 2015 was approximately 1,566 bbl per day prior to the start of operations of Blocks III
and IV, and approximately 3,306 bbl per day from April to December 2015, following the start of operations. We also own and operate a gas processing plant which processes and fractions natural gas from its liquids in northern Peru 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 Consorcio Terminales and Terminales del Peru both of which have contracts with Petroperú, the other
state owned oil and gas company, to operate fuel storage terminals.

LOGOLOGO

Oil and Gas Production

We operate and extract oil from four 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, which 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 100 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 2015 was 1,389 barrels of crude oil. We operate 236 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 from April to December 2015, following the start of operations in April 2015, was 1,175 barrels of
crude oil. We operate 198 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 between the
provinces of Talara and Paita, department of Piura, in northern Peru, approximately eighteen 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 from April to December 2015, following the start of operations in April 2015, was 612 barrels of crude oil. We operate 236 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 nine 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 2015 in this field was
162 barrels of crude oil. We operate 52 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.

##### Table of Contents

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 prices, which include Fortis Blend, Suez Blend and Oman crudes. During 2013, 2014 and 2015, we received an average fee of US$84.99, US$ 77.33 and US$45.59 per barrel
of extracted oil, which was equivalent to approximately 78.2%, 78.1 % and 84.26%, respectively, of average Brent crude prices in the same years. According to our hydrocarbons development contracts, we are required to deliver all the oil and gas we
produce, regardless of its quantity, to Perupetro. Therefore, we are not committed to provide a fixed and determinable quantity of oil or gas in the near future under existing contracts.

We produce natural gas as a byproduct of the production of crude oil (an average of 9.5 MMCF per day during 2015). 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.

Estimated Proved Reserves:

The
following table sets forth estimated proved crude oil and natural gas reserves in Blocks I, III, IV and V as of December 31, 2015. We have only included estimates of proved and have not included any estimates of probable and possible reserves.

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 2015, which, pursuant to our contractual agreements, resulted in average oil and gas prices of US$ 54.11 per barrel and US$1.08 per Mcf, respectively, throughout the remaining terms of our service and license
contracts.

Proved undeveloped reserves in the fields as of December 31, 2015 were 19,317 Mboe, consisting of 14,559 Mbbl of crude oil and
26,720 MMcf of natural gas. We estimate that during 2015 approximately 174 Mboe, or 108 Mbbl, of crude oil and 458 MMcf, or 81 Mboe, of natural gas of proved undeveloped reserves, were converted into proved developed reserves. Due mainly to the
start of operations of Blocks III and IV in April 2015, we estimate that during 2015 proved undeveloped reserves increased 19,138 Mboe, consisting of an increase of 4,759 Mboe (26,720 MMcf) of natural gas and an increase of 14,559 Mbbl of crude oil.
Capital expenditures, for both drilling activities and workovers, made during 2015 to convert undeveloped reserves to prove developed reserves amounted to approximately US$4.7 million.

The principal changes in proved undeveloped reserves during 2015 were:



| | ● |  | Crude oil reserves: proved undeveloped crude oil reserves increased 14,559 Mbbl during 2015 mainly as a result of the start of operations of Blocks III and IV in 2015.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Natural associated gas reserves: proved undeveloped natural gas reserves increased 4,759 Mboe (26,720 MMcf) during 2015 mainly as a result of the starts of operations of Blocks III and IV in 2015.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For changes in proved developed and undeveloped reserves from December 31, 2012 to December 31, 2015, see supplementary data (unaudited)
annexed to our audited annual consolidated financial statements included in this annual report.

Qualifications of Technical Persons and
Internal Controls Over Reserves Estimation Process:

The reserves estimates shown in this annual report have been prepared internally by
our engineers in accordance with the definitions and guidelines of the SEC. Our reservoir engineers and geoscience professionals have worked to ensure the integrity, accuracy and timeliness of the data, methods and assumptions used in the
preparation of the reserves estimates. Mr. Victor Salirrosas is our Reservoir Engineer and head of our staff of reservoir engineers and geoscience professionals. The reserves estimate report was submitted to our Committee of Reserves Development,
which is formed by Mr. Iván Miranda Zuzunaga (Exploration and Production Manager), Mr. Jose Pisconte Lomas (Chief of Geology) and independent consultants (including Mr. Humberto Barbis Valderrama, GMPs former Exploration and Production
Manager until December 2013). The Committee of Reserves Development reviews the report and relays it for approval to the board of directors of GMP together with its recommendations with respect to the estimation and categorization of reserves. Mr.
Salirrosas holds a Petroleum Engineering degree from Universidad Nacional de Ingeniería in Lima, Peru and has 42 years of experience, most of it as a reservoir engineer at Perupetro and GMP. Mr. Salirrosas is also a professor of reservoir
engineering and enhanced oil recovery in the Petroleum Engineering School of Universidad Nacional de Ingeniería in Lima, Peru. In addition, Mr. Miranda Zuzunaga, our Exploration and Production Manager, holds a degree in Petroleum Engineering
from Universidad Nacional de Ingeniería in Lima and a Petroleum Engineering Masters degree from Texas A&M University of Texas, and has 33 years of experience in the oil industry. Mr. Pisconte Lomas, Chief of Geology, holds a
Geologist Engineering degree and a Regional Geology masters degree from Universidad Nacional Mayor de San Marcos and has 26 years of experience in the oil industry. Furthermore, the board of directors of GMP has in the past contracted two
independent extraction consultants who are highly experienced in the oil and gas industry and who review the methodology used for the estimation of reserves.

|(2) | Hydrocarbons extracted from Blocks I and V belong to Perupetro, which in turns pays us a per barrel fee for lifted hydrocarbons. Hydrocarbons extracted from Blocks III and IV belong to GMP, which in turn pays Perupetro
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.

##### Table of Contents

During 2013, 2014 and 2015 we invested US$17.8 million, US$25.6 million and US$3.8 million,
respectively, in drilling activities. We drilled a total of four wells during 2015 (three of them located in Block I and one located in Block V). All of them are productive wells.

The company is drilling an average of 0.33 wells per month in its quest to recover some proved reserves. Most of the drilling is undertaken in
Block I where environmental permits allow us to drill up to 96 new wells. From time to time, based on geological analysis, we try to obtain more oil by increasing the depth of our productive formations. In this way, we minimize exploratory risks.

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, 2015, we estimated that we will be required to close 65 wells in Block I in December 2021 and 13 wells in Block V in October 2023, out of approximately 332 wells currently not in production. We have created a
provision in our financial statements for the costs relating to those well closings. See notes 4.1 (d) and 17 to our audited annual consolidated financial statements included in this annual report. As of December 31, 2015 we did not have an
estimation regarding the number of wells required to be closed for Blocks III and IV.

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 18.1 MMcf per day during 2013, 27.3 MMcf
per day during 2014, and 31.7 MMcf per day during 2015. 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,

while the total amount of the additional investment, which will be reimbursed, is approximately US$ 186 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 for an additional year until August 2015, which was then extended for two more years until August 2017 through a contract amendment subscribed in 2015. The total amount of the
additional investment required during this two year period, which will be reimbursed, is approximately US$ 25 million. A new public biding has not been scheduled but is expected to take place at the end of 2016 or during 2017. We cannot assure you
that we will be awarded the new contract or that the terms of such potential new contract will not differ materially from those of our current contract.

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.

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 2013, 2014 and 2015 Consorcio Terminales and Terminales del Perú generated revenues of US$48.7 million, US$44.5
million and US$66.8 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 2015, this terminal dispatched 27.8 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 2015 dispatched 31,601 tonnes of sodium hydrosulfide for international mining companies. During 2013, 2014 and 2015
these activities generated revenues in the aggregate of approximately US$4.2 million, US$4.1 million and US$2.3 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.

Real Estate

Our Real Estate segment is
one of the largest apartment building developers in Peru, in terms of number of units sold and value of sales in 2015, and is focused on the development and sale of affordable housing and housing as well as other real estate projects. Since
commencing our operations in 1987, we have developed approximately 656,793 m2 of affordable housing (approximately 9,926 units); approximately 310,478 m2 of housing (approximately 1,574 units); approximately 162,875 m2 of office space (approximately
884 offices); and approximately 43,000 m2 of shopping centers (three shopping centers). Moreover, we are currently building approximately 80,790 m2 of affordable housing (approximately 1,276 units); approximately 49,743 m2 of housing (approximately
148 units); and approximately 3,631 m2 of office space (approximately 17 offices, with an average size of 214 m2 each). Our Real Estate segment also owns significant land parcels in Lima, comprising of approximately 862 hectares as of December 31,
2015, and we have sold undeveloped land in the past and intend to continue such sales in the future.

Principal Real Estate Activities

Our real estate developments include the following products:

| | ● |  | 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 14 affordable housing projects. As of December 31, 2015, we are developing eight affordable housing projects, which are in various stages of development, including seven which are in the construction phase
and one for which we have purchased land, but are 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/.51,800 and S/.259,000). 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).

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/.1,860) 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/.15,400 and S/.19,250). 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, 2015, we are developing two 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.

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 two office buildings 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.); and Panorama project, which is in the development phase, and expected to be two 17-floor
towers of office buildings including a shopping zone (35% of which is owned by us and 65% of which is owned by Inversiones Maje S.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, 2015, we owned approximately 943 hectares, of which 81% is located in Lima and 19% outside of Lima. We continually evaluate opportunities
to purchase new land for our real estate development projects

We have a 50.0% interest in Project Espacio (formerly known as Cuartel San
Martín) with Urbi Propiedades S.A. of Intergroup Financial Services Corp. owning the remaining 50.0%. Espacio Project is a 68,000 m2 former ex-military base located in Limas upscale Miraflores district, where we plan to invest
approximately US$680 million to develop a premium mixed-use development consisting of approximately 98,000 m2 of housing, 68,000 m2 of office towers, a 61,000 m2 shopping mall, and a 48,000 m2 luxury hotel and conference center. Although we are
still in the pre-construction approval phase and have not yet obtained all required building permits, we plan to begin construction of this project in the fourth quarter of 2016 and expect to complete the project through multiple stages within seven
years.

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.

We also own a minority 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. We expect to develop affordable housing projects on the land once water and sewage services become available. Our
proportional interest in this land is not included in our land bank.

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, Inmobiliari S.A., 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. 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 5,332 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) 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. Nowadays our main focus is 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.

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%.

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 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 nuevos 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.

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, 2015 was US$4,037.8 million. We expect to recognize as revenues 38.0% of our backlog by December 31, 2016, 32.0% of our backlog by December 31, 2017, and 30.0% of our backlog thereafter. The following table
sets forth the growth of our consolidated backlog from December 31, 2011 to December 31, 2015.

Our backlog may not grow at recent historic rates and may decline. We cannot assure you that we
will be able to continue obtaining sufficient contracts in the future in number and magnitude to continue 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. The chart below sets forth our consolidated backlog breakdown by end-market, geography and client sector as of December 31, 2015.

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, 2015 was
US$3,129.4 million. We expect to recognize as revenues 37% of our backlog by December 31, 2016, 31% of our backlog by December 31, 2017 and 32% of our backlog thereafter. The following table sets forth the growth of our E&C backlog from December

E&C Backlog Growth (in US$ million)

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 Gasoducto Sur Peruano project, and, as a result,
we incorporated US$1.0 billion in backlog.

The following pie charts set forth our E&C backlog breakdown by end-market, geography,
client sector and contract type as of December 31, 2015.

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.

##### Table of Contents

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.

Corporate Social Responsibility

We seek
to create value in the long-term, conducting business in an economically viable manner, which is also beneficial to society at large and respectful of the environment. We aim to continue building trust among our stakeholders. In order to achieve
these objectives, we have formulated a strategy based on two fundamental pillars: (1) ensuring responsible management of our operations (which we call the internal front), and (2) sharing welfare with society through education and civic behavior
(which we call the external front).

To encourage a responsible management we have defined six priorities on which we focus our internal
management efforts: ethical behavior, personal development, operational excellence, health and safety, environment and communication. We also seek to transcend our businesses, promoting the growth of our different stakeholders through training and
community involvement. To achieve this goal, our companies deploy various programs that respond not only to the needs of their business and operations but also to the needs of the communities of which they form part. Some of these programs are:



| | ● |  | Our social support program Ayni is intended to achieve the sustainability of our affordable housing projects by encouraging responsible and committed participation of the new owners of our real estate
projects. As part of this initiative, we offer them training on legal and administrative matters, conflict management and leadership, and provide them with continuing support to foster a better quality of life in these urban spaces. In 2015, 2,107
families were trained in leadership skills and harmonious coexistence under this program.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Through our Metro Culture program, we transform our trains and train stations into centers of social and cultural education. According to two 2015 polls, an average of 88.5% of the users of the Lima
Metro think we have contributed to generate better citizens.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Our Road Education program seeks to transfer our culture of accident prevention by training users and communities in the vicinity of the roads we operate or maintain. In order to implement this
initiative, we have established partnerships with local school boards and use the Ministry of Educations Guidelines on Road Safety Education.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Our Development of Local Labor Capacity (Programa Desarrollando capacidades Laborales en las Zonas de Influencia) program improves the employability of the local population, providing training
that directly promotes their employment in our projects as well as providing other construction-related workshops which contribute to their involvement in community affairs. Since its creation in 2006, more than 21,000 persons have participated in
this program, receiving more than 962,000 hours of training.Thanks to the program, in 2015, 54% of those trained were able to work on GyM projects, substantial amounts of the skilled labor (assistant or workman category) was obtained
from local communities.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Through our Construction Management Educational program, we developed and imparted the technical career Planning and control of construction projects, which seeks to increase employability
of low income youth. This program, which we carry out in alliance with Fe y Alegría, has a 2-year duration and is mostly taught by our employees, who participate as internal teachers. It also includes professional apprenticeships in our
company and enables graduates to obtain a mid-level technician certification from the Ministry of Education.

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, govern 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.

The selection processes are established in Article 32
of Supreme Decree No. 350-2015-EF as follows:



| | ● |  | public biddings (licitación pública), applicable to goods and works;
| | - |  | --------------------------------------------------------------------



| | ● |  | public tenders (concurso público), applicable to services, including consulting services;
| | - |  | -----------------------------------------------------------------------------------------



| | ● |  | simplified award (adjudicación simplificada), applicable to (i) goods, if the value is greater than S/. 31,600 and less than S/. 400,000; (ii) services, if the value is greater than S/. 31,600 and less
than S/. 400,000; and (iii) works, if the value is greater than S/. 31,600 and less than S/. 180,000;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | ● |  | direct contracting (contratación directa), applicable to goods and services, in situations of emergency arising from catastrophic events, involvement of national security, shortages, among other similar
reasons.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

With the exception set forth in Article 49 of the Supreme Decree No. 350-2015-EF, the selection processes include
the following phases:



| | ● |  | in the case of public biddings, public tenders and simplified award: notice; registration of participants; submission and reply of inquiries; submission and reply of comments; preparation of the terms and
conditions of the selection process; submission of bids; evaluation and qualification of bids; and adjudication;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | in the case of the selection of individual consultants: notice; registration of participants; submission of bids; evaluation and qualification of bids; and adjudication; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | in the case of price comparison: notice; submission of bids; and adjudication.
| | - |  | ------------------------------------------------------------------------------

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 construction and a consulting company, respectively.

Article 14 of the Supreme Decree No. 350-2015-EF establishes the types of contracts that may be entered into by public entities:



| | ● |  | lump-sum (sistema a suma alzada), applicable when the amounts, magnitudes and quality are determined in the terms and conditions of the selection process. The bidder submits its proposal indicating a fixed amount
and a term for the completion of the agreement;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | unit price, rates or percentages (sistema de precio unitario, tarifas o porcentajes), applicable when the nature of the service to be provided does not allow accurate determination of the required quantities; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



95

##### Table of Contents

| | ● |  | lump-sum and unit price, rates or percentages mix (esquema mixto de suma alzada y precios unitarios), applicable when accurate determination of the quantities required for some of the components cannot be made.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Article 15 of 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 Controller (Contraloría General de la
República) regarding violations to the regulation when damages are caused against the state.

At 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 (in reciprocal obligations neither party is in default, except when one of them has either
fulfilled its obligation or delivered a guarantee of fulfillment). GyM, GMI and Stracon GyM 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), declared that construction activities in Peru are in the public interest and of preferential national interest. 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
regulation; (ii) possessing the organization and infrastructure that guarantee the feasibility of the project;

##### Table of Contents

(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 the construction including the work 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.

Safety
Regulation in Construction Projects



| | ● |  | The Law on Safety and Health at Work (Law No. 29783) is intended to promote workplace accident prevention and applies to all business sectors. The principal safety rules applicable to construction projects include the
following:
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | companies with 20 or more employees must establish a committee for the promotion of workplace safety and health that oversees the implementation of the required internal safety and health regulation policy;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | all projects must have a safety and health plan consisting of all the technical and administrative mechanisms to guarantee the physical integrity and health of workers and third parties during project execution;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

approved by Supreme Decree No. 005-2012-TR, and with Occupational Health Manual, approved by Ministerial Resolution No. 510-2005-MINSA;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | companies must provide for medical examinations of its employees prior to, during and at the termination of their employment;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| | ● |  | companies must show a safety and health plan; an index of frequency; and the companys performance in safety and health in order to be awarded public and private projects;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | use of individual protective equipment, including gloves, safety goggles, boots and helmets, is mandatory when risks to safety and health cannot be prevented by other means; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | personnel responsible for safety must comply with all requirements in Rule NTP 399.010.1 for fire prevention.
| | - |  | -------------------------------------------------------------------------------------------------------------

The Peruvian Ministry of Labor and Employment Promotion, the National Superintendence of Labor Inspection (SUNAFIL) and the Peruvian Ministry
of Health are the competent organisms in the safety and health fields, respectively.

evaluating and remedying potential sources of danger.

Mining

GyM and Stracon GyM must comply with the Mining Occupational Health and Safety Regulation, approved by Supreme Decree No. 055-2010-EM, and
other related regulations for their mining-related construction activities including the construction of mineral processing plants and other mining-related buildings, among others. In developing mining projects, our subsidiaries personnel must
follow the safety programs and be familiar with internal rules from their mining client. The Peruvian Ministry of Labor and Employment Promotion and OSINERGMIN are the authorities responsible for supervising and enforcing compliance of the foregoing
rules. The most relevant of the safety rules with which GyM and Stracon GyM must comply include: (i) creating an internal safety and health regulation policy and selecting a manager responsible for its implementation; (ii) monitoring and recording
workplace accidents and occupational diseases; (iii) providing information to employees regarding the safety risks related to their work; (iv) providing employees necessary first aid and medical attention in the event of a workplace accident; (v)
providing employees the necessary tools, equipment or materials to perform their activities safely; (vi) evaluating risks in order to establish accident prevention and mitigation plans.

Oil and Gas

GyM must
comply with the Hydrocarbons Safety Regulations, as approved by Supreme Decree No. 043-2007-EM, which are enforced by the OSINERGMIN. The most relevant safety rules with which GyM must comply include: (i) assuring that senior project managers are

98



---

##### Table of Contents

According to Supreme Decree No. 005-2008-EM mining contractors must register with the National
Mining Contractors and Specialized Companies Registry. GyM and Stracon GyM are currently registered. Proper registration requires the filing of a request with the Regional Agency of Energy and Mines with jurisdiction in the area where the mining
activities will take place. In addition, within five days upon commencement of construction, GyM and Stracon GyM must provide in writing their employees with the following information: (i) the companys legal name; (ii) the scope of the
contract; (iii) the place of execution; (iv) the applicable health and safety regulations; (v) the Safe Work Written Procedures (PETS); and, (vi) risk insurance policies.

Labor Law Requirements in Civil Construction

Labor law requirements in civil construction consist of the specific legal framework for civil construction workers and the general legal
framework applicable to the administrative personnel in the civil construction sector set forth in the Single Revised Text of the Labor Productivity and Competitiveness, approved by Supreme Decree No. 003-97-TR.

Seasonality of services is one of the main features in the specific legal framework 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) remuneration increase; (ii) bonuses for employees working 28 consecutive days or more in
projects with difficult access; and (iii) paid leave in case of the 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 and Stracon GyM have 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 the compliance and enforces
environmental rules related to mining, oil and gas, and electricity.

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

Civil Construction

The
Supreme Decree No. 015-2012-VIVIENDA (modified by Supreme Decree No. 004-2015-VIVIENDA) regulates the environmental aspects of projects related to housing, urbanism, construction and sanitation activities in



99



---

##### Table of Contents

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 initiating construction works: (i) projects expected to cause minor environmental impacts require an environmental impact statement; (ii) projects expected to cause moderate environmental impacts require an
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 they operate, GyM and Stracon GyM are 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 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 its 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

supervising and enforcing compliance, of any suspicious activity.

Infrastructure

Infrastructure and Public Services through Private-Public 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, ancillary services, applied research projects and/or technological innovation, through Public-Private Partnerships (PPP) and Projects with State Assets. This new legal framework has been in
force since December 28, 2015, and we anticipate that it will have positive effects for the public administration and, as a consequence, for our projects, as it is expected to improve the Peruvian states administrative procedures and budget
management.

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



| | 1. | The Ministry of Economy and Finance (Ministerio de Economia 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, 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, 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: (i)
in the case of self-financed projects, taxes and tolls to be collected from final consumers; (ii) in the case of co-financed projects, subsidies and payments from the public entity awarding the project; and (iii) any other financing structure agreed

Each of our
subsidiaries Norvial, Survial, Canchaque and GyM Ferrovías has entered into a concession agreement with ProInversión and the Peruvian Ministry of Transport 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 Transport 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 principal 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.



102

##### Table of Contents

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.

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



103

##### Table of Contents

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)according to the applicable law.

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



| | ● |  | filing 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

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 fifteen years; however the parties agreed to extend the duration of the agreement to an
additional eighteen 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 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



105

##### Table of Contents

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, US$8
million, US$0.8 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 the urban areas under their jurisdiction. Peruvian
regulation establishes that urban zoning refers to the division of a municipal jurisdiction in zones for specific usages, such as residential, commercial, industrial or mixed-use.

The main zoning rules applicable to our real estate projects include 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 required to obtain an environmental
authorization from the Housing, Urbanism, Regularization or Construction National Directorate of the Peruvian Ministry of Housing, Construction and Sanitation and to comply with the provisions set forth in the corresponding environmental impact
assessment.

|A. | Operating Results
|-- | -----------------

Overview

We are the largest engineering and construction company in Peru as measured by revenues during 2015, and the largest publicly traded
engineering and construction company in Latin America as measured by market capitalization as of December 31, 2015, 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.

Factors Affecting Our
Results of Operations

General

Peruvian and Chilean Economic Conditions

85.0%, 80.1% and 72.9% of our revenues in 2013, 2014 and 2015 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 10.6%, 14.4%, and 12.1% of our revenues

##### Table of Contents

in 2013, 2014 and 2015 were derived from activities in Chile. Our percentage of Chilean revenues has grown as a result of our acquisition of Vial y Vives in October 2012 and DSD Construcciones y
Montajes in August 2013. Following our acquisition of Morelco in December 2014, 9.3% of our revenues in 2015 were derived from activities in Colombia.

The Peruvian economy has been one of the fastest growing economies globally over the past decade, with the Peruvian real GDP growing at an
average rate of 3.8% during the three years from 2013 to 2015 as a result of, among other factors, robust domestic demand and increased private and public investment. With increasing disposable income and an expanding middle class, private
consumption grew at an average annual rate of 4.3% in real terms from 2013 to 2015. In 2013 private investment increased at an average rate of 6.5% in real terms, driven by an increase in projects primarily in the mining, oil and gas, energy,
transportation, telecommunications and manufacturing sectors. In 2014 and 2015 private investment decreased at an average rate of 2.2% and 4.3%, 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 2.9% in 2013, 3.2% in 2014 and 4.4% in 2015. The nuevo sol depreciated versus the U.S. dollar by 9.6% in 2013, 6.9% in 2014, and 14.1% in 2015. Given its recent performance with regard to fiscal
balance, debt/GDP ratio, net reserves and high liquidity, Perus sovereign debt is rated investment grade and was upgraded to BBB+ by S&P and Fitch in August 2013 and October 2013, respectively, and Baa2 by Moodys in August 2012.
According to the IMF, the Peruvian economy is projected to grow at rates of 4.2% and 5.0% in 2016 and 2017, respectively.

The Chilean
economy grew at an average annual rate of 2.9% during the three years from 2013 to 2015 in real terms, mainly driven by strong domestic demand. Total fixed investment grew at an annual average rate of 1.1% in real terms during the three years from
2013 to 2015. Inflation in Chile, as measured by the change in the consumer price index, was 3.0% in 2013, 4.6% in 2014 and 4.3% in 2015. The Chilean peso depreciated versus the U.S. dollar by 9.4% in 2013, 16.0% in 2014 and 17.0% in 2015. Chilean
sovereign debt was rated A+ by Fitch in October 2013, AA- by S&P in December 2013 and Aa3 by Moodys in October 2013, the highest sovereign debt ratings in Latin America.

The Colombian real GDP grew at an average annual rate of 4.1% during the three years from 2013 to 2015. Inflation has increased during recent
years, with inflation of 1.9% in 2013, 3.6% in 2014 and 6.7% in 2015. The Colombian peso depreciated against the U.S. dollar by 9.3% in 2013, 23.0% in 2014 and by 34.1% in 2015. Colombias sovereign debt was rated BBB by Fitch in December 2013
and S&P in April 2013, and Baa2 by Moodys in July 2014.

From 2011 to 2015 our revenues grew at a CAGR of 16.6% (13.2% excluding
acquisitions)

##### Table of Contents

under IFRS. Our organic revenues grew 5.4% in 2015 from 2014. We expect, but cannot assure you, that in the future our business will tend to grow in line with the performance of and investment in
the end-markets we serve.

Fluctuations in Exchanges Rates

We estimate that in 2015, 56.6%, 21.0% and 22.4% of our revenues were denominated in nuevos soles, U.S. dollars and other currencies
respectively, while 71.1%, 5.9% and 23.0% of our cost of sales during the year were denominated in nuevos soles, U.S. dollars and other currencies. In addition, as of December 31, 2015, 56.0%, 33.1% and 11.0% of our total debt was denominated in
nuevos 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 nuevo sol appreciates against the U.S. dollar, our operating margins
tend to decrease; when the nuevo sol depreciates against the U.S. dollar, our operating margins tend to increase (if everything else were held equal). Conversely, the appreciation of the nuevo sol against the U.S. dollar tends to decrease our
indebtedness and financial expenses as expressed in nuevos soles; and the depreciation of the nuevo sol against the U.S. dollar tends to increase our indebtedness and financial expenses as expressed in nuevos soles. We enter into derivatives, from
time to time, to hedge part of our financial exposure to currency fluctuations. The value of the nuevo sol to the U.S. dollar depreciated in 2013, 2014 and 2015, 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 and Chilean 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 2015 represented 29.8% of our cost of sales and 52.0% of our administrative expenses;
services provided by third parties, which in 2015 represented 41.0% of our cost of sales and 33.4% of our administrative expenses; and inputs (including raw materials), which in 2015 represented 15.4% of our cost of sales. For a breakdown of our
cost of sales and administrative expenses, see note 26 to our audited annual consolidated financial statements included in this annual report.



115

##### Table of Contents

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 2013 to 2014 our personnel charges increased by 22.1% and from 2014 to 2015 our personnel charges increased by 14.2%.
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 2013 to 2014 our costs related to
services provided by third parties increased by 38.5% and from 2014 to 2015 our costs related to services provided by third parties increased by 38.9%. The principal inputs we use are fuel, cement and steel, which in the aggregate represented a
majority of our total input costs in 2015. Our costs for these inputs are affected by, among other factors, the growth 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 2013 to 2014, our input costs increased by 1.1% and from 2014 to 2015, our input costs decreased by 4.7%.

Acquisitions

We acquired a 75.0%
interest in CAM in February 2011 for US$10.8 million, after post-closing adjustments. In 2011, as a result of the excess over fair value of the assets and liabilities we acquired in the CAM acquisition over the consideration paid, we recognized a
gain of S/.45.2 million, which is reflected in gain from business combination. In 2012, 2013, 2014 and 2015, we reversed provisions amounting to S/.68.0 million, S/.13.7 million, S/.9.4 million and S/.7.8 million, respectively, relating
to labor and tax contingencies and trade liabilities that we had reflected on our balance sheet in connection with the CAM acquisition because we determined that the underlying contingencies and liabilities had become remote, expired or been
resolved; these reversals are reflected under other income (expenses). For further information, see notes 28 and 32 to our audited annual consolidated financial statements included in this annual report.

In addition, we acquired a 74.0% interest in Vial y Vives in October 2012 for US$55.6 million and an additional 6.4% interest in Vial y Vives
between June and August 2013 for US$3.4 million. The inclusion of Vial y Vives further increased and diversified our revenues, in addition to complementing our expertise in the E&C mining sector; however, the historic operating margins of Vial y
Vives have tended to be lower than those of our E&C segment because of its relatively higher administrative expenses.

In August 2013,
we acquired an 86.0% interest in DSD Construcciones y Montajes for US$37.2 million. DSD Construcciones y Montajes is an entity headquartered in Chile whose main business activities are electromechanical works and assemblies in construction projects
of oil refineries, pulp and paper, power plants and mining plants in Chile and Latin America. This acquisition is part of our plan to increase our presence in markets that present high growth potential, such as Chile, and in attractive industries,

such as energy and mining. Accordingly, DSD Construcciones y Montajes results are only reflected in our results of operations for four months in 2013 and for the full year in 2014 and 2015. In
2015, Vial y VivesDSD represented 7.5% of our consolidated revenues, while it caused a decrease of 2.2% in our consolidated gross profit and of 20.8% of our consolidated operating income.

In December 2013, we acquired an additional 16.9% interest in Norvial from the former shareholder Besco S.A. for S/.51.4 million (US$18.4
million), increasing our stake in Norvial to 67.0%. 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 March 2014, we acquired control of Coasin for an amount of US$2.1 million.

In December 2014, we acquired a 70% interest in Morelco for S/.277.1 million (US$93.7 million). Morelco is an engineering and construction
company focused in the Colombian oil and gas and other energy sectors. 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 2015, Morelco represented 8.1% of our consolidated revenues, 11.3% of our consolidated gross profit and 15.3% of our consolidated operating income.

In December 2014, we 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 includes goodwill resulting from the purchase amounting to S/.61.4 million. COGA is a jointly controlled entity and accordingly we will reflect its results in Share of the profit or loss in associates and
joint ventures under the equity method of accounting. For a description of our alliance with CCPIB, see Item 4.B. Information on the CompanyBusiness OverviewInfrastructure.

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. In addition, our subsidiary GyM S.A. participates with a 29% stake in the construction consortium for this project, which represented approximately US$1.0 billion of our backlog as of
December 31, 2015.

In August 2015, we acquired 44% of Adexus S.A., an information technology firm in Chile, for an approximate value of
US$13.8 million (S/. 44.1 million). In January 2016 we acquired an additional 8% stake in Adexus for an approximate value of US$ 2.5 million.

Cyclicality

Our Engineering and
Construction segment is cyclical as a result of being closely

##### Table of Contents

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 2015, we identified a material weakness 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

##### Table of Contents

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 2013 to 2015, our E&C segment has trended towards contractual arrangements that pose less risk for us (i.e.,
costplus fee and, to a lesser extent, unit price), which provide more stability to our results but lower gross margins. 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, have increased financing needs for working capital. We managed to stabilize working capital requirements by the end of 2015.

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 2.4% from 2013 to 2014 and 6.6% from 2014 to 2015 (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 nuevo 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.

##### Table of Contents

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 in the third quarter of 2016. We estimate that Norvials capital
investment for the second stage will be approximately US$100 million.

On August 8, 2013, we obtained a 40-year term concession for
designing, financing, building, operating and maintaining the infrastructure associated with the Vía Expresa Sur project. This project involves the second stage expansion of the Via ExpresaPaseo de la República, between Av.
República de Panamá and Panamericana highway. The estimated investment in this concession is expected to be US$196.8 million. The contract gives us the right to charge public service users according to a pre-defined price list;
however, the grantor (government) has agreed to pay the difference if the revenues generated during the operation stage are lower than US$18 million in the first two years and US$19.7 million from the third year until the fifteenth year. Revenue for
the construction activities and other initial activities are accounted for as a financial asset for the portion that the government guarantees, and as an intangible for the unguaranteed investment. The project is expected to be in operation by the
end of 2018.

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 2013 and 2015 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. In 2013, we generated losses as a result of delays in the start of operations of new trains, which was postponed because of delays in approvals from the
Ministry of Transportation. However, during the fourth quarter of 2013, with a larger quantity of trains in operation, our results improved and generated operating profits for the year. 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, 2015, GyM Ferrovías has spent a total of US$195.5 million in capital expenditures in connection with the Lima Metro.

Energy

A part of the
revenues in our Infrastructure segment depends on global prices for

##### Table of Contents

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 licensing 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 2013, 2014, and 2015 average Brent crude prices were approximately US$108.64, US$99.02, and US$52.46 per barrel and the average fee we received in these years was US$84.99, US$77.33 and US$43.35 per barrel
of extracted oil, respectively. As of April 14th, 2016, the Brent crude price was approximately US$42.82 per barrel and our fee was approximately US$40.53 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
18.1 MMcf per day during 2013, 27.3 MMcf per day during 2014, and 31.67 MMcf per day during 2015.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; however, our contract for the operation of the South terminals expires in August 2017.

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, 2015, we have seven concessions as well as long-term government contracts in this segment, including the concession for Via Expresa Sur, the terms of
which was agreed in August 2013 and the concession for Chavimochic, which was agreed in May 2014. 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 and we are currently providing information requested by the Peruvian Ministry of Economy and Finance prior to the projects approval. We believe this concession will increase the
results of operations of our Infrastructure segment. However, we cannot assure you that we will be able to negotiate this contract on favorable terms or at all. In addition, our government contract to operate the South fuel storage terminal is
scheduled to expire in August 2017, and we cannot assure you that it will be extended or renewed 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, which includes the design, financing, engineering and procurement, and the operation and maintenance of the project until 2048. The southern gas pipeline is scheduled to begin operations in 2018.

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 1,757, 831 and 835 units in 2013, 2014 and 2015, respectively.

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.

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 obtained three public-sector road contracts at the
end of 2010 as well as three new public-sector road contracts at the end of 2012; however, two public sector road contracts expired in December 2012 and were not renewed until May and June, respectively, of 2013, and, as a result, impacted our
results of operations during 2013. 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 different contracts with Provías
Nacional (Sullana, La Merced, Iacapal and Bappo). 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.

Critical Accounting Estimates and Judgments

Estimates and judgments used in connection with the preparation of our financial statements 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.

Critical Accounting Estimates and Assumptions

We make estimates and assumptions concerning our future economic performance. These estimates and assumptions are required to be made because
the information used in the presentation of the financial information is currently not available, is dependent on future events, or cannot be calculated with a high degree of accuracy. The resulting accounting estimates will, by definition, seldom
equal the related actual results. If outcomes in the next fiscal year are much different than current assumptions, a material adjustment might be required to the carrying amount of the assets and liabilities. The estimates and assumptions that have
a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities in subsequent years are addressed below.

Estimated Impairment of Goodwill and Other Intangible Assets with Indefinite Useful Life

Impairment reviews are undertaken annually or more frequently if there is a triggering event, to determine if goodwill arising from business
acquisitions and other intangible assets with indefinite useful life have suffered any impairment, in accordance with the policy described in note 2.15 (a) to our audited annual consolidated financial statements included in this annual report. For
this purpose, goodwill is attributed to the different cash-generating units to which it relates, while other intangible assets with indefinite useful life are assessed individually. The recoverable amounts of the cash-generating units and of other
intangible assets with indefinite useful life have been determined based on the higher of: (i) their value-in-use and (ii) their fair value less costs of sale. This evaluation requires the exercise of our 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 the preparation of future cash flows, macro-economic forecasts as well as defining the interest rate at which said cash flows
will be discounted.

Value in use is usually determined on the basis of discounted estimated future net cash flows. Determination as to
whether and how much an asset is impaired involves our management estimates of highly uncertain matters such as future commodity prices, the effects of inflation on operating expenses, discount rates, production profiles and the outlook for global
or regional market supply-and-demand conditions for crude oil, natural gas and refined products.

If we experience a significant drop in
revenues or a drastic increase in costs or changes in other factors the fair value of business units might decrease. If our 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 the 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
necessary.

##### Table of Contents

Based on the impairment tests performed by our management, no goodwill nor intangible
(trademarks) impairment losses were required to be recognized because the recoverable amount of the cash-generating units subject to testing was substantially higher than their related carrying amounts. We have not had any impairment to goodwill or
intangibles over the last three years.

The most significant assumptions are: revenue, gross margin, growth rate and discount rate which
are included in note 17 of our audited annual consolidated financial statements included in this annual report. We have performed a sensitivity analysis, increasing or decreasing the assumptions of gross margin, discount rate and revenue by 10%,
with all the other variables held constant, which is included below:



| | a. | Gross Margin: Our fair value is above its carrying amount and, if the gross margin were adjusted down by 10%, the fair value would be 26.04% higher than the carrying amount and, if the gross margin were adjusted up by
10%, the fair value would be 88.26% higher than carrying amount. Therefore our businesses would still be greater than the carrying amount even under a significant decline in our gross margin and we would not need to impair our goodwill.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b. | Discount Rate: Our fair value is significantly above its carrying amount and, if the discount rate were adjusted down by 10%, the fair value would be 76.64% higher than the carrying amount, and if the discount rate were
adjusted up by 10%, the fair value would be 39.42% higher than carrying amount. Therefore our businesses would still be greater than the carrying amount even under a significant upward adjustment to the discount rate in value and we would not need
to impair our goodwill.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c. | The group would have recorded a provision for impairment of goodwill resulting from the Engineering and Construction cash generation unit.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------



| | d. | In 2014, if gross margin had been 10% less than managements estimates, the group would have recorded a provision for impairment of goodwill resulting from the cash generation unit of IT goods and services.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As a result of our sensitivity analysis, provisions for impairment of goodwill and/or trademarks would have not been necessary to be
recorded under any other scenarios.

Income Taxes

Determination of the tax obligations and expenses requires interpretations of the applicable tax laws and regulations. We seek legal tax
counsels advice before making any decision on tax matters. Although our 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 by taking the temporary
differences of the tax basis of assets and liabilities and the financial statement basis using the tax rates in effect for each of the years in which the difference is expected to reverse. Any change in tax rates will affect the deferred tax assets
and liabilities. This change will be recognized in income in the period 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, we take into consideration all available positive
and negative 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.

Our maximum exposure related to tax contingencies amounts to S/.37.9 million (US$11.1 million).

Percentage-of-Completion Revenue Recognition

Revenue from construction contracts is recognized under the percentage-of-completion method which requires the final margin from construction
contracts to be estimated. Projections of these margins are performed by our management based on work execution budgets and adjusted periodically based on updated information reflecting the actual performance of work. The estimated contract revenue
and total cost estimates are reviewed often as work progresses and is approved. In this regard, our management considers that the estimates made at the year-end closing are reasonable. When unapproved change orders occur, revenue is recognized equal
to costs incurred (no profit component recognized) until the additional work is approved.

Contract revenue is recognized as revenue in
the income statement in the accounting periods in which the work is performed. Contract costs are recognized as cost of sales in the income statement in the accounting period in which the work to which they relate is performed. However, any expected
and probable excess of total contract costs over total contract revenue for the contract is expensed immediately. Furthermore, any changes in contract estimates are recognized as a change in accounting estimates and recognized in the period the
change is made and in future periods as applicable. In certain construction contracts, the terms of these agreements allow for an amount to be withheld by the customers until construction has been completed. Under these contracts the full amount may
not be recognized until the next operating cycle. As of December 31, 2013, 2014 and 2015, a sensitivity analysis was performed considering a 10% increase/decrease in our gross margins as follows:

Provision for Well Closure Costs

We estimate the present value of our 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 our statement of financial position. The discount pre-tax rate used for the present value calculation was 2.09% based on the 7 year bond
rate as of December 2015 (2.17% based on the 10 year bond rate as of December 2014). As of December 31, 2015 the present value of the estimated provision for closure activities for 78 wells amounted to S/. 7.3 million (S/.7.2 million as of December
31, 2014 for closure activities for 78 wells). The well closure liability is adjusted to reflect the changes that resulted from the passage of time and from revisions of either the date of occurrence or the amount of the present value of the
obligations originally estimated.

##### Table of Contents

If, at December 31, 2015 and 2014, the estimated rate would have increased or decreased by 10%,
with all variables held constant, the impact on pre-tax profit would have not been significant.

During 2015, the Company recorded a
provision amounting to S/0.1 million to reflect the estimated obligation to close productive wells included in the service agreements for Blocks I and V (S/2.7 million in 2014). The provision for Blocks III and IV at December 31, 2015 is nil because
at year-end 2015 there was no available information regarding the number of wells required to be closed.

Critical Judgments in Applying Accounting
Policies

Consolidation of Entities in Which We Holds Less Than 50%

We own certain direct and indirect subsidiaries that we control even though we have less than 50% of the voting rights. These are mainly
related to indirect subsidiaries in our Real Estate segment that are owned through Viva GyM, where, even though we hold an interest between 30% and 50%, we have the power to affect the relevant activities that mostly impact such subsidiaries
returns. Additionally, we have de facto control of Promotora Larcomar S.A. in which we hold 46.6% of equity interest, considering the fact that the ownership of the other 53.5% is disperse.

New Accounting Pronouncements, Amendments and Interpretations

New standards, amendments and interpretations adopted by us in 2015

We used for the first time the following IFRS and amendments to IFRS in the preparation of our financial statements for 2015:



| | ● |  | IFRS annual improvements for 2010-2012 and 2011-2013 cycles.
| | - |  | ------------------------------------------------------------



| | ● |  | Defined Benefit Plans: Employee contributions  amendment to IAS 19, Employee Benefits.
| | - |  | -----------------------------------------------------------------------------------------

Adoption of annual improvement for the 2010-2012 and 2011-2013 cycles have only required additional minor disclosures. These improvements have
not had a significant impact on the current and prior years and they are not likely to affect future periods.

New standards and amendments and
interpretations effective for the financial statements for annual periods beginning on or after January 1, 2016 not yet adopted

The
following new standards and amendments and interpretations effective for the financial statements for annual periods beginning on or after January 1, 2016 have not yet adopted by the group, and have not been applied in preparing the consolidated
financial statements included in this annual report:



| | ● |  | IFRS 9, Financial instruments, addresses the classification, measurement and recognition of financial assets and financial liabilities. The complete version of IFRS 9 was issued in July 2015. It replaces the
guidance in IAS 39 that relates to the classification and measurement of financial instruments.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | IFRS 9 retains but simplifies the mixed measurement model and establishes three primary measurement categories
for financial assets: amortized cost, fair value through Other Comprehensive Income and fair value through Profit and Loss. The basis of classification depends on the entitys business model and the contractual cash flow characteristics of the
financial asset. Investments in equity instruments are required to be measured at fair value through profit or loss with the irrevocable option at inception to present changes in fair value in Other Comprehensive Income not recycling. There is now a
new expected credit losses model that replaces the incurred loss impairment model used in IAS 39. For financial liabilities there were no changes to classification and measurement except for the recognition of changes in own credit risk in other
comprehensive income, for liabilities designated at fair value through profit or loss. IFRS 9 relaxes the requirements for hedge effectiveness by replacing the bright line hedge effectiveness tests. It requires an economic relationship between the
hedged

| | item and hedging instrument and for the hedged ratio to be the same as the one management actually use for risk management purposes. Contemporaneous documentation is still required
but is different to that currently prepared under IAS 39. The standard is effective for accounting periods beginning on or after January 1, 2018. Early adoption is permitted. We are assessing the impact of this new standard.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | IFRS 15, Revenue from contracts with customers. The standard replaces IAS 18 Revenue and IAS 11 Construction contracts and related interpretations. The new standard is based on the
principle that revenue is recognized when control of a good or service transfers to a customer  so the notion of control replaces the existing notion of risks and rewards. The newly issued standard introduces a five-step process for revenue
recognition, as follows: (i) identifying the contract with a customer, (ii) identifying separate performance obligation, (iii) determining the transaction price, (iv) allocate the transaction price to the separate performance obligations and (v)
Recognize Revenue When (or as) Performance Obligations Are Satisfied. The application of IFRS 15 may have an effect on the timing and amount of revenue recognition as well as on the business processes, systems and internal controls that may require
changes for adequately meeting the new requirements. Entities have the option of a full retrospective application and a retrospective application with additional disclosures. The standard is effective for annual periods beginning on or after January
1, 2018 and earlier application is permitted. We are assessing the impact of IFRS 15, and is not expected to have a significant impact on revenue recognition. We are considering transition options established for IFRS 15 and the effect on the
current contracts signed with the other subsidiaries.

| | ● |  | Amendments to IFRS 11, Joint arrangements. The amendments to IFRS 11 clarify the accounting for the acquisition of an interest in a joint operation where the activities of the operation constitute a
business. They require an investor to apply the principles of business combination accounting (NIIF 3) when it acquires an interest in a joint operation that constitutes a business. This includes: (i) measuring identifiable assets and liabilities at
fair value, (ii) expensing acquisition-related costs, (iii) recognizing deferred tax, and (iv) recognizing the residual as goodwill, and testing this for impairment annually. Existing interests in the joint operation are not remeasured on
acquisition of an additional interest, provided joint control is maintained. The amendments also apply when a joint operation is formed and an existing business is contributed.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | IAS 1 Presentation of financial statements disclosure initiative. The amendments to IAS 1 Presentation of Financial Statements are made in the context of the IASBs Disclosure Initiative, which explores
how financial statement disclosures can be improved. The amendments provide clarifications on a number of issues, including:
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Materiality: an entity should not aggregate or disaggregate information in a manner that obscures useful information. Where items are material, sufficient information must be provided to explain the impact on the
financial position or performance.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Disaggregation and subtotals: line items specified in IAS 1 may need to be disaggregated where this is relevant to an understanding of the entitys financial position or performance. There is also new guidance on
the use of subtotals.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | OCI arising from investments accounted for under the equity method: The amendments require that the share of other comprehensive income arising from investments accounted for under the equity method is grouped based on
whether the items will or will not subsequently be reclassified to profit or loss. Each group should then be presented as a single line item in the statement of other comprehensive income.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Notes: confirmation that the notes do not need to be presented in a particular order.
| | - |  | -------------------------------------------------------------------------------------



| | ● |  | IFRS 16 Leases. On January 13, 2016, IFRS 16, Leases (IFRS 16) was issued replacing the
current guidance (IAS 17, Leases and IFRIC 4, Determining whether an arrangement contains a lease and other related standards). IFRS 16 introduces a new definition of a lease and a new accounting model that will have a
material impact on lessees. As a result of the new accounting treatment, an entity is required to recognize in the statement of financial position, at the inception of the lease, an asset for the right of use of the leased asset and a

| | liability for the obligations to make future contractual payments. At initial recognition, the asset and liability will be measured at the present value of the minimum lease payment under
contract. As a result of this change, a large number of leases classified as operating leases under the current standards will be shown on the face of the statement of financial position from the inception of the lease. This new
accounting model is applicable to all contracts qualifying as leases, excepted for those contracts with an effective period of less than 12 months (considering in that determination the likelihood of contract extension) and lease contracts of assets
that are considered immaterial. The standard applies to annual periods beginning on or after January 1, 2019, with earlier application permitted if IFRS 15, Revenue from Contracts with Customers, is also applied.

We are currently evaluating the impact these standards may have on the preparation of our financial statements. There are no other IFRSs
or IFRIC interpretations that are not yet effective that would be expected to have a material impact on our financial statements.

Accounting for
Subsidiaries, Joint Operations and Associated Companies

Results of our subsidiaries, joint operations and associated companies are
reflected in our financial results. We refer to our subsidiaries as those entities over which we exercise control, principally GyM, Stracon GyM, Morelco, GMP, GMD and Concar. 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. We refer to business activities in which we share control with
unrelated entities as joint operations. Our joint operations are 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. Our principal joint operations are Consorcio Terminales, Consorcio Constructor Chavimochic and Concesionaria La Chira. 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 of which the principal are Promoción Inmobiliaria del Sur S.A, Bechtel V&V and Panorama Plaza Negocios S.A., 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, see note 2.2 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 2015, we obtained 5.3% of the revenues in our E&C segment from the construction of La Chira waste water treatment plant for our Infrastructure segment and the construction of
real estate for our Real Estate segment; 28.2% 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 14.4% 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 6 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 10% of the contract price, 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.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | On August 8, 2013, we obtained the concession for a 40-year term for designing, financing, building, operating and maintaining the infrastructure associated with Vía Expresa Sur. We are currently working to
obtain the necessary rights of way for the highway. Revenue for the construction activities and other initial activities are accounted for as a financial asset for the portion that the government guarantees to us, and as an intangible for the
unguaranteed investment.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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 and other infrastructure for the Peruvian
government; and (iii) fees related to interest we charge the Peruvian government in connection with the amounts we invest to purchase such trains and other infrastructure. In 2015, the fees related to items (i), (ii) and (iii) were S/.164.02
million, S/.0.0 million and S/.42.7 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. 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: Beginning in March 2012, we obtained 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 begins operations, which is expected to occur at the beginning of 2016, we
will obtain revenues only for operation and maintenance services, which we will recognize in the period in which the services are performed. During the construction phase, cost of sales for La Chira includes 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 will 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 2015, our cost of land that is allocated to units delivered during these periods amounted to S/.20.3 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 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.

(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 increased by 11.8%, or S/. 823 million, from S/.7,008.7 million for 2014 to S/.7,832.4 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 17.7%, or S/.1,072.5 million, S/.6,057.1 million for 2014 to S/.7,129.6 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 26.1%, or S/.248.8 million, from S/.951.6 million for 2014 to S/.702.7 million for 2015. Our gross margin (i.e. gross profit as a percentage of revenues) for 2015 was 9.0% 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.

Administrative Expenses

Our administrative expenses decreased by 2.0%, or S/.8.0 million, from S/.421.4 million for 2014 to S/.412.4 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/.41.2 million, from S/.15.1 million for 2014 to S/.57.3 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/.30.6 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 37.9% or S/.206.9 million, from S/.545.3 million for 2014 to S/.338.4 million for 2015. Our operating margin
(i.e., operating profit as a percentage of revenues) was 4.3% 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 16.0%, or S/.805.9 million, from S/.5,035.7 million for 2014
to S/.5,841.6 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.

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

E&C Activities: For 2015, approximately 2.9%, 27.6%, 23.7%, 35.4% and 10.8% of our E&C revenues were derived from: engineering
services; electromechanic construction; civil construction; contract mining; and building construction activities, respectively. For 2014, approximately 7.2%, 21.6%, 35.0%, 26.2% and 10.1% of our E&C revenues were derived from: engineering
services; electromechanic construction; civil construction; contract mining; and building construction activities, respectively. For 2013, approximately 6.4%, 17.8%, 29.5%, 29.3% and 17.0% of our E&C revenues were derived from: engineering
services; electromechanic construction; civil construction; contract mining; and building construction activities, respectively. Despite variations in the proportional weight of our various E&C activities, the revenues derived from most of our
E&C activities increased in absolute terms during 2015, except for engineering services and civil construction, which decreased 58.3% and 32.1%, respectively. For a description of our E&C business activities, see Item 4.B. Information
on the CompanyBusiness OverviewEngineering and ConstructionPrincipal Engineering and Construction Activities;

E&C Contracts: For 2015, approximately 28.1%, 49.2%, 10.9%, 9.0% and 3.0% of our E&C revenues were derived from: cost-plus fee;
unit price; lump-sum; EPC contracts and other contracts, respectively. For 2014, approximately 43.9%, 29.5%, 11.4% and 15.3% of our E&C revenues were derived from: cost-plus fee; unit price; lump-sum; and EPC contracts, respectively. For 2013,
approximately 53.0%, 30.9%, 7.3% and 8.8% of our E&C revenues were derived from: cost-plus fee; unit price; lump-sum; and EPC contracts, respectively. During 2015 we continued to derive significant revenues from unit price, cost-plus fee
contracts and lump-sum contracts. For a description of our contractual arrangements, see Item 4.B. Information on the CompanyBusiness OverviewEngineering and ConstructionContracts and Factors Affecting our
Results of OperationsEngineering and Construction;

E&C End-Markets: For 2015, approximately 60.0%, 9.0%, 10.0%,
16.0%, 3.0%, 2.0% and 1.0%, of our E&C revenues were derived from: mining; real estate buildings; power; oil and gas; transportation; water

and sewage; and other end-markets, respectively. For 2014, approximately 70.4%, 10.4%, 10.2%, 2.6%, 4.2%, 1.2% and 1.1%, of our E&C revenues were derived from: mining; real estate buildings;
power; oil and gas; transportation; water and sewage; and other end-markets, respectively. For 2013, approximately 54.5%, 17.1%, 7.6%, 6.6%, 9.3%, 4.4% and 0.6%, of our E&C revenues were derived from: mining; real estate buildings; power; oil
and gas; transportation; water and sewage; and other end-markets, respectively. During 2015 we experienced growth in the revenues from the oil and gas end-market. Revenues in 2015 derived from the real estate buildings, oil and gas, water and
transportation end-markets decreased in comparison with 2014.

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 33.0%, or S/.178.1 million, from S/.535.4 million for 2014 to S/.357.3 million for
2015. Our E&C gross margin for 2015 was 6.1% compared to 10.6% for 2014. This decrease in E&C gross margin was primarily due to lower margins in two civil construction projects as a result of higher than expected costs.

Operating Profit. Our E&C operating profit decreased 63.0%, or S/.168.3 million, from S/.267.0 million for 2014 to S/.98.7 million
for 2015. Our E&C administrative expenses decreased 12.0%, or S/.30.6 million, which resulted in administrative expenses as a percentage of revenues of 4.9% 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 1.7% 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.

##### Table of Contents

Our Infrastructure revenues increased 15.6% or S/.138.3 million, from S/.884.8 million for 2014
to S/.1,023.2 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 26.5%, or S/.44.3 million, increase in revenues, from S/.167.0 million for 2014 to S/.211.0 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

Our Infrastructure gross profit decreased 21.4%, or S/.52.6 million, from S/.245.6 million for 2014 to
S/.193.0 million for 2015. Our Infrastructure gross margin was 18.9% 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 65.2%, or S/.30.7 million, from net financial expenses of S/.47.1 million for 2014 to net financial expenses of S/.16.4 million for 2015. Our net exchange
difference decreased S/.20.0 million, from a loss of S/.44.3 million for 2014 to a loss of S/.24.3 million for 2015. This decrease is due to both the depreciation of the nuevo sol against the U.S. dollar from 2014 to 2015, partially offset by the
replacement of dollar-denominated debt with nuevos soles denominated debt.

Share of Profit and Loss in Associates

Our share of profit and loss in associates decreased S/.35.8 million from a profit of S/.53.4 million in 2014 to a profit of S/.17.6 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, partially offset by profits generated by Gasoducto Sur Peruano.

Income Tax

Our income tax decreased 48.3%, or S/.70.6 million, from S/.146.2 million for 2014 to S/.75.6 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 34.8% and 28.8%, respectively.

Net Profit

Our net profit decreased 60.8%, or S/.219.4 million, from S/.361.1 million for 2014 to S/.141.7 million for 2015. Net profit
attributable to controlling interests decreased 70.6%, while net profit attributable to non-controlling interests decreased 12.8%. Net profit attributable to non-controlling interests decreased primarily due to our E&C and Real Estate segments.

Revenues

Our total revenues increased by 17.4%, or S/.1,041.2 million, from S/.5,967.5 million for 2013 to S/.7,008.7 million for 2014. This increase
was due mainly to growth in our E&C segment, primarily due to an increase in electromechanic construction and civil construction activities. In addition, we experienced growth in our Infrastructure segment, primarily due to an increase in
revenues from the Lima Metro, as a result of the increase in trains in operation, Survial, as a result of higher levels of maintenance for the road, and Norvial, as a result of the recognition of the work progress for the second stage of the road.

We estimate that fluctuations among the nuevo sol and the U.S. dollar and the Chilean peso between the 2013 and 2014 resulted in an
increase in our consolidated revenues, as expressed in nuevos soles, of approximately S/.217.8 million, or 3.1%, during 2014, as the nuevo sol depreciated against the U.S. dollar by approximately 6.9% and appreciated against the Chilean peso by
approximately 7.7%.

The following table sets forth a breakdown of our revenues by segment for 2013 and 2014.

Cost of Sales

Our total cost of sales increased by 22.0%, or S/.1,093.7 million, from S/.4,963.4 million for 2013 to S/.6,057.1 million for 2014. 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.

We estimate that fluctuations among the nuevo sol and the U.S. dollar and the Chilean peso between 2013 and 2014 resulted in an increase in
our consolidated cost of sales, as expressed in nuevos soles, of approximately S/.56.4 million, or 0.9%, during 2014.

Gross Profit

Our gross profit decreased by 5.2%, or S/.52.5 million, from S/.1,004.1 million for 2013 to S/.951.6 million for 2014. Our gross margin for
2014 was 13.6% compared to 16.8% for 2013. 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, our Technical Services segment,
primarily due to the impact of the cancellation of one of the road maintenance contracts, and our Real Estate segment, primarily due to lower margins in the units delivered and the lower number of units.

Administrative Expenses

Our administrative expenses increased by 16.5%, or S/.59.6 million, from S/.361.8 million for 2013 to S/.421.4 million for 2014, primarily due
to the increase of administrative expenses in the E&C segment, specifically in Vial y Vives  DSD; and an increase in administrative expenses in our Infrastructure segment, specifically our subsidiaries GyM Ferrovías and Canchaque.
As a percentage of revenues, our administrative expenses decreased to 6.0% in 2014 from 6.1% in 2013.

Other Income (Expenses)

Our other income (expenses) decreased S/.10.2 million, from S/.25.3 million for 2013 to S/.15.1 million for 2014. This decrease was primarily
due to a decrease in our E&C segment, from a S/.10.5 million profit to a S/. 9.9 million loss, as a result of a lower reversal of provisions in connection with the Vial y Vives acquisition and a lower reversal of provisions in connection with
the CAM acquisition, as well as a lower reversal of provisions in connection with tax and labor-related contingencies. For further information, see Factors Affecting Our Results of OperationsAcquisitions.

Operating Profit

Our operating
profit decreased 19.0% or S/.128.0 million, from S/.673.3 million for 2013 to S/.545.3 million for 2014. Our operating margin (i.e., operating profit as a percentage of revenues) was 7.8% for 2014 compared to 11.3% for 2013. This decrease is
primarily due to the decrease in gross profit and by the increase in administrative expenses in our E&C and Infrastructure segments and lower other income (expenses). The following table sets forth a breakdown of our operating profit by segment
for 2013 and 2014.

Revenues. Our E&C revenues increased 23.6%, or S/.960.4 million, from S/.4,075.3 million for 2013
to S/.5,035.7 million for 2014, primarily due to the growth in revenues in our electromechanic and civil works activities and, to a lesser extent, to contract mining activity as well as the S/.679.6 million in revenues from Vial y VivesDSD in
which we acquired controlling interests in October 2012 and August 2013, respectively.

We estimate that fluctuations among the nuevo sol
and the U.S. dollar between 2013 and 2014 resulted in an increase in our E&C revenues, as expressed in nuevos soles, of approximately S/.223.2 million, or 4.4%, during 2014.

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

E&C Activities: For 2014, approximately 7.2%, 21.6%, 35.0%, 26.2% and 10.1% of our E&C revenues were derived from: engineering
services; electromechanic construction; civil construction; contract mining; and building construction activities, respectively. For 2013, approximately 6.4%, 17.8%, 29.5%, 29.3% and 17.0% of our E&C revenues were derived from: engineering
services; electromechanic construction; civil construction; contract mining; and building construction activities, respectively. Despite variations in the proportional weight of our various E&C activities, the revenues derived from most of our
E&C activities increased in absolute terms during 2014, except for building construction activity which decreased 31.3%. For a description of our E&C business activities, see Item 4.B. Information on the CompanyBusiness
OverviewEngineering and ConstructionPrincipal Engineering and Construction Activities;

E&C Contracts: For
2014, approximately 43.9%, 29.5%, 11.4% and 15.3% of our E&C revenues were derived from: cost-plus fee; unit price; lump-sum; and EPC contracts, respectively. For 2013, approximately 53.0%, 30.9%, 7.3% and 8.8% of our E&C revenues were
derived from: cost-plus fee; unit price; lump-sum; and EPC contracts, respectively. During 2014 we continued to derive significant revenues

from cost-plus fee and unit price contracts, with a significant increase in EPC and lump-sum contracts. For a description of our contractual arrangements, see Item 4.B. Information on the
CompanyBusiness OverviewEngineering and ConstructionContracts and Factors Affecting our Results of OperationsEngineering and Construction; and

E&C End-Markets: For 2014, approximately 70.4%, 10.4%, 10.2%, 2.6%, 4.2%, 1.2% and 1.1%, of our E&C revenues were derived from:
mining; real estate buildings; power; oil and gas; transportation; water and sewage; and other end-markets, respectively. For 2013, approximately 54.5%, 17.1%, 7.6%, 6.6%, 9.3%, 4.4% and 0.6%, of our E&C revenues were derived from: mining; real
estate buildings; power; oil and gas; transportation; water and sewage; and other end-markets, respectively. During 2014 we experienced growth in the revenues from the mining and power end-markets. Revenues in 2014 derived from the real estate
buildings, oil and gas, water and transportation end-market decreased in comparison with 2013.

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 4.3%, or S/.24.1 million, from S/.559.5 million for 2013 to S/.535.4
million for 2014. Our E&C gross margin for 2014 was 10.6% compared to 13.7% for 2013. This decrease in E&C gross margin was primarily due to lower margins in two civil construction projects as a result of higher than expected costs.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2013 and 2014 resulted in an increase in our E&C cost of
sales, as expressed in nuevos soles, of approximately S/.71.5 million, or 1.6%, during 2014.

Operating Profit. Our E&C
operating profit decreased 24.2%, or S/.85.4 million, from S/.352.4 million for 2013 to S/.267.0 million for 2014. Our E&C administrative expenses increased 18.6%, or S/.40.6 million, which resulted in administrative expenses as a percentage
revenues of 5.1% for 2014 compared to 5.3% for 2013, due to the increase in administrative expenses of Vial y Vives  DSD as a result of the consolidation of DSD in 2014 (in 2013 it was consolidated as from September 2013). Our E&C
operating profit for 2014 was negatively impacted by S/.9.9 million in other income, mainly resulting from the reversal of provisions in connection with the Vial y Vives acquisition. Our E&C operating margin for 2014 was 5.3% compared to 8.6%
for 2013.

In addition, our E&C segment had S/.48.2 million in profit from minority interests held by Vial y Vives in several of its
projects undertaken in 2014 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 29.9% or S/.203.8 million, from S/.681.0 million for 2013 to S/.884.8
million for 2014. The variation in our Infrastructure revenues principally reflected the following:



| | ● |  | Toll Roads: a 72.6%, or S/.142.3 million, increase in revenues, from S/.195.9 million for 2013 to S/.338.2 million for 2014, primarily due to the recognition of the work progress for the second stage of the
Norvial toll road and an increase in the revenues of Survial due to higher levels of maintenance activities, specifically construction activities in the area of Urcos and related to catastrophic events that occurred in 2010;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Mass Transit: a 40.9%, or S/.48.5 million, increase in revenues, from S/.118.5 million for 2013 to S/.167.0 million for 2014, primarily due to the increase of trains in operation from five trains in 2012 to 14
(including two backup trains) beginning in September 2013 to 24 trains (including the backup trains) in September 2014;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Water Treatment: a 35.6%, or S/.16.2 million, decrease in revenues, from S/.45.5 million for 2013 to S/.29.3 million for 2014, primarily due to progress in the construction of the La Chira waste water treatment
plant; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Energy:a 9.1%, or S/.29.2 million, increase in revenues, from S/.321.1 million for 2013 to S/.350.3 million for 2014 primarily due to a 10.0% growth in our barrel daily production (BDP 1,754 vs BDP 1,595 in
2013) resulting from increased drilling of wells and the performance of certain wells, despite a decrease in international oil prices (average price per basket of oils of US$97.1 bbl vs. US$107.4 bbl), in addition to higher processing levels at the
our gas processing plant which increased from 6,603.4 MMcf in 2013 to 9,999.2 MMcf in 2014.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We estimate that fluctuations
among the nuevo sol and the U.S. dollar between 2013 and 2014 resulted in an increase in our Infrastructure revenues, as expressed in nuevos soles, of approximately S/.25.8 million, or 2.9%, during 2014.

Revenues. Our Real Estate revenues decreased 28.4%, or S/.89.1 million, from to S/.313.7 million for
2013 to S/.224.6 million for 2014. This decrease was primarily due to a 52.7% decrease in the number of units delivered, with 831 units delivered in 2014 compared to 1,757 units delivered in 2013. This decrease in delivered units is due to the
timing of completion of units and the effects of the deceleration of the Peruvian economy. In addition, this decrease in revenues of our Real Estate segment results from sales by Almonte in 2013 of S/.16.3 million compared to S/.0.6 million in 2014.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2013 and 2014 resulted in an increase in our Real Estate
revenues, as expressed in nuevos soles, of approximately S/.3.4 million, or 1.5%, during 2014.

Gross Profit. Our Real Estate gross
profit decreased 45.1%, or S/.51.3 million, from S/.113.7 million for 2013 to S/.62.4 million for 2014, mainly as a result of the decrease in the number of units delivered and lower margins in units delivered in 2014 compared to 2013, when more
affordable housing units with higher margins were delivered. Our Real Estate gross margin was 27.8% for 2014 compared to 36.2% for 2013.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2013 and 2014 resulted in an increase in our Real Estate cost of
sales, as expressed in nuevos soles, of approximately S/.1.2 million, or 0.8%, during 2014.

Our Technical Services operating profit decreased 64.0%, or S/.45.7 million, from S/.71.4 million
for 2013 to S/.25.7 million for 2014. Our Technical Services operating margin for 2014 was 2.1% compared to 6.1% for 2013. The variation in our Technical Services operating profit principally reflected the following:



| | ● |  | Operation and Maintenance of Infrastructure Assets: a 280.6%, or S/.34.8 million, decrease in operating profit, from a S/.12.4 million profit for 2013 to a S/.22.4 million loss for 2014, primarily due to the
impact generated because of the cancellation of one of the road maintenance contracts. Our Operation and Maintenance of Infrastructure Assets operating margin was (6.1)% for 2014 compared to 2.9% for 2013;

| | ● |  | IT Services: a 18.6%, or S/.3.6 million, decrease in operating profit, from S/.19.4 million for 2013 to S/.15.8 million for 2014, primarily due to the decrease in the gross profit. Our IT Services operating
margin was 6.4% for 2014 compared to 8.6% for 2013; and

| | ● |  | Electricity Networks Services: a 18.4%, or S/.7.3 million, decrease in operating profit, from S/.39.6 million for 2013 to S/.32.3 million for 2014, primarily due to lower reversal of provisions in 2014 (S/.9.4
million) than in 2013 (S/.13.6 million) in connection with the CAM acquisition which offset the increase in gross profit between the two periods; and also explained by the sale of CAM Peru, with a loss of S/2.1, as described in Factors
Affecting Our Results with OperationAcquisitions. Our Electricity Network Services operating margin was 5.4% for 2014 compared to 7.7% for 2013.

Financial (Expense) Income, Net

Our net financial expense decreased S/.21.0 million from net financial expenses of S/.112.4 million in 2013 to net financial expenses of
S/.91.4 million in 2014. Excluding foreign exchange differences, our net financial expense increased 9.0%, or S/.3.9 million, from net financial expenses of S/.43.2 million for 2013 to net financial expenses of S/.47.1 million for 2014. This
increase was primarily due to additional debt incurred in the Lima Metro for project financing and the E&C segment for working capital purposes. Our exchange difference, net decreased S/.26.1 million, from a loss of S/.70.4 million for 2013 to a
loss of S/.44.3 million for 2014. This decrease is due to both the depreciation of the nuevo sol against the U.S. dollar from 2013 to 2014, partially offset by the replacement of dollar-denominated debt to nuevos soles.

Share of Profit and Loss in Associates

Our share of profit and loss in associates increased S/.18.7 million from a profit of S/.33.6 million in 2013 to a profit of S/.53.4 million
in 2014. This increase is primarily due to our Real Estate segment, the sale of a parcel of land in the south of Lima, property of Prinsur, company where we hold minority participation, as well as certain engineering and construction projects in
Vial y Vives where we have a minority participation.

Income Tax

Our income tax decreased 19.8%, or S/.36.1 million, from S/.182.3 million for 2013 to S/.146.2 million for 2014. This decrease in income tax
was primarily due to a decrease in profit before tax. Our effective tax rates for 2013 and 2014 were 30.7% and 28.8%, respectively.

Net Profit

Our net profit decreased 12.4%, or S/.51.0 million, from S/.412.1 million for 2013 to S/.361.1 million for 2014. Net profit
attributable to controlling interests decreased 6.3%, while net profit attributable to non-controlling interests decreased 33.2%. Net profit attributable to non-controlling interests decreased primarily due to our E&C and Real Estate segments.

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 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. Delays in obtaining payments from our E&C clients during 2015, in particular in the mining sector, have increased financing needs for working capital. We managed to stabilize working capital requirements by the end of 2015. 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, and our current financing sources are
sufficient to satisfy our current capital expenditures and debt service obligations through the next twelve months. We anticipate financing future acquisitions, infrastructure investments and land purchases with a combination of cash from
operations, additional indebtedness and/or financial contributions from partners.

At December 31, 2015, our cash and cash equivalents
totaled S/.554.1 million (US$162.3 million), of which S27.9 million (US$8.2 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 2013, 2014 and 2015.

Cash Flow from Operating Activities

Net cash flow used in operating activities in 2015 was higher than in 2014. For 2015 this reflects an increase in accounts payable, accounts
receivables and inventory of S/.47.6 million, mainly related to the proportional consolidation of Consorcio Constructor Ductos del Sur. In addition to this, efforts from GyM S.A. to collect account receivables was successful enough to reduce them in
S/. 112.6 million.

Net cash flow used in operating activities in 2014 was lower than in 2013. For 2014 this reflects an increase in
accounts payable of S/.120.7 million mainly related to the reduction of the advance payments from clients in our E&C segment, and the increase in accounts receivables of S/.578.1 million mainly due to our E&C segment.

Cash Flow from Investing Activities

Net
cash flow used in investing activities in 2015 was higher than in 2014. This mainly reflects the purchase of a 20% stake of Concesionaria Gasoducto Sur Peruano.

Net cash flow used in investing activities in 2014 was higher than in 2013. This primarily reflects the purchase of machinery and equipment,
and acquisition of COGA, Morelco, Coasin and the additional stake in Stracon GyM.

Cash Flow from Financing Activities

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.

Net cash flow provided by financing activities in 2014 was
lower than in 2013. This is primarily due to the issuance of ADSs in 2013. In 2014, we financed our investing activities with the proceeds from the issuance of ADSs plus an increase in our indebtedness.

Indebtedness

As of December 31,
2015, we had a total outstanding indebtedness of S/.2,575.4 million (US$754.6 million) as set forth in the table below.

##### Table of Contents

Leasing. As of December 31, 2015, we were party to numerous leasing agreements with
several financial institutions which in the aggregate amounted to approximately S/.295.3 (US$ 86.5 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/.56.7 million (US$16.6 million) as of December 31, 2015.This loan accrues interest at an annual rate of three month LIBOR plus: (i) 1.75% if, at the installment
payment date, the exchange rate between the nuevo 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: (1) Leverage Ratio (as defined therein) shall not be greater than 1.50;
(2) DebtService Coverage Ratio (as defined therein) shall not be less than 1.20; (3) Liquidity Ratio (as defined therein) shall not be less than 1.10; and (4) Debt Coverage Ratio (as defined therein) shall not be greater than 2.20. As
of the date of this annual report, we were in compliance with these financial covenants.

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 the third disbursement for S/.80 million is due in July 2016. 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. Part of 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 is expected to be used to finance the construction of the second stage of Ancon  Huacho Pativilca
highway and the financing of the value added tax linked to the implementation of the project expenses.

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 Graña y Montero S.A.A. 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 we have to
quarterly fund the debt service reserve account 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.

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; and (iv) liens on certain accounts. The agreement contains certain
covenants, including the obligation by G&M to maintain the following financial ratios during the term of the agreement: (1) the Consolidated EBITDA to Consolidated Interest Expense Ratio (as defined therein) shall not be less than 3.5:1.0 at any
time; (2) the Consolidated Leverage Ratio (as defined therein) shall not be greater than 4.5:1.0 at any time during the period commencing on the closing date and ending on March 31, 2016; 3.5:1.0 at any time between April 1, 2016 and December 31,

In August

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 the foreign exchange risk on the amount to be received in U.S. dollars as proceeds from a loan agreement with Banco de Crédito del Peru in connection with the construction of

we will find opportunities on terms that we consider to be favorable to us, whether we will be able to take advantage of such opportunities should they arise, or the timing of and funds required by such opportunities. In addition, we expect to
finance these opportunities with a combination of cash on hand, new borrowings and/or financial contributions from partners, depending on a variety of commercial considerations at such time. See Part I. IntroductionForward-Looking
Statements.

Our Main Market: Peru

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 2011 to 2015. According to the Peruvian Central Bank, Peruvian real GDP grew at an average rate of 4.8% 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.

In addition, the countrys strong economic growth has led to a 2.3% increase in GDP per capita from US$5,881 in 2011 to
US$6,017 in 2015. Average annual inflation, measured by the change in the CPI index, was 3.6% in the period from 2011 to 2015.On the other hand, Perus Nuevo Sol, depreciated from an average of S/.2.75 per US$1.00 in 2011 to
an average of S/.3.19 per US$1.00 in 2015, a depreciation of 15.7%. Perus sovereign debt has been granted investment grade rating by S&P, Fitch and Moodys. At the end of 2015, 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 2011 to 2015.

This expansion was mainly driven by a strong domestic demand in real terms: fixed investment grew on average at 4.6%per year and total consumption grew on average at 4.7%per year during the five years from 2011 to 2015. Inflation has remained stable since 2011, averaging 3.6%between 2011 and 2015, in line with the Chilean Central Banks inflation target of 3% +/- 1%. Chiles
sovereign debt has the highest rating in the region, rated AA- by S&P (December 2012), Aa3 by Moodys (October 2013) and A+ by Fitch (October 2013).

|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.



163

##### Table of Contents

Directors are elected at a shareholders meeting and hold office for three years. Directors
may be elected to multiple terms. Our bylaws allow a Board with a number of Directors ranging between seven and nine. Our current board of directors is composed of eight directors with no alternates. We elected nine Directors for the current period
but one of them (Mr. Jose Chlimper) resigned in December 2015 to participate in the presidential campaign of Keiko Fujimori, and no replacement has been designated as of the date of this annual report. 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 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.

Board of Directors

The following sets forth our directors and their respective positions as of the date of this annual report. All directors were elected at our
annual shareholders meeting held on March 28, 2014, and their term expires in March 2017, on the third anniversary from the date of election. Mr. José Chlimper resigned from its position in December 2015 to participate in the
presidential campaign of Keiko Fujimori, and no replacement has been designated as of the date of this annual report.

our subsidiaries board of directors. In 2015, total compensation paid to our executive officers amounted to S/.25,559,169. See Item 4.B Information on the CompanyBusiness OverviewRegulatory MattersLabor
Regulations for additional information on profit sharing regulatory requirements.

Neither we nor any of our subsidiaries have
entered into any agreement that provides for any benefit or compensation to any director or senior executive upon expiration of his or her term or termination of employment. Under Peruvian law, unless we dismiss someone for justified cause, we are
required to pay the dismissed employee (but not directors) 1.5x annual salary for every year with the company for a period not to exceed 12 years. We are not required to make such payments in the event of voluntary termination. Although we have no
ongoing obligation to do so, in the past we have provided, and in the future we may provide, such benefits to our executive officers upon their retirement. We have not set aside or reserved any amounts to provide for pension, retirement or other
similar benefits.

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.

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 and Social Responsibility Committee of our board of directors.

|D. | Employees
|-- | ---------

We have developed an extensive and talented team, including more than 3,600
engineers, that 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, 2015, we had a total of 32,906 full-time employees, including approximately 11,206 manual laborers, a number that
fluctuates depending on our project backlog. At such date, we also worked with 3,857 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, 2015, 42% of our employees worked outside Peru. The following table sets forth a breakdown of our employees by
category as of December 31, 2015.

Total Employees

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 eightyears 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 2015, 72% 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, and GMD were recognized by Great Place to Work
® as being among the 45 best companies to work for in Peru. In April 2015, our subsidiary Viva GyM was recognized by Great Place to Work among the best 25 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 2015, we invested more than US$7.5 million in
continuing education, reaching approximately 386,047 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 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 the personnel in our gas processing plant belongs to the labor union Unicode Workers Union GMP S.A. In addition, 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 2015, the Graña y Montero Group (including our four business areas) reached
a total of 127,379,277 hours worked. During this period, we reported an accident frequency index (FI) of 0.39 accidents calculated over 200,000 hours worked. In 2014, we completed 124,422,434 hours worked with an accident frequency index of
0.59 accidents calculated over 200,000 hours worked. In 2013, our frequency index was 0.49 calculated over 117,584,768 hours worked.

Our
occupational health and safety management system in our subsidiaries GyM, GMP, GMI, GMD and CAM and Vial y Vives  DSD and Morelco 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. We train our employees in safety, environment, occupational health and related topics, and have trained and certified experts in risk management and prevention
who disseminate and regulate risk prevention standards and procedures. To ensure safe conditions, we perform preventive and routine maintenance on all of our properties, worksites, systems and machinery, and make repairs and replacements when
necessary or appropriate. We also conduct routine and required inspections of those properties in accordance with applicable regulation. Furthermore, we continually monitor, test, and record the effectiveness of our safety measures and assure that
the highest risk segments receive the highest priority for scheduling internal inspections or tests for integrity.

|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).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



180



---

##### Table of Contents

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.

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 and Social Responsibility 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.

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. As of December 31,
2015, we had recorded provisions amounting to S/.15.0 million in connection with legal and administrative proceedings. See note 22 to our audited annual consolidated financial statements included in this annual report.

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. 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.

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.

##### Table of Contents

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.

corporate status to a publicly held corporation. As of December 31, 2015, Lima Stock Exchange had a share capital of S/. 71,482,810, divided into 68,172,377 class A shares and 3,310,433 class B shares of par value S/.1.00
each. Class A shares are entitled to one vote per share while class B shares do not have voting rights. As of December 31, 2015, the Lima Stock Exchange had 147 class A shareholders and 63 class B
shareholders.

Trading on the Lima Stock Exchange is primarily done on an electronic trading system that became operational in August
1995. From the second Sunday of March through the first Sunday of November of each year, trading hours are Monday through Friday (except holidays) as follows: 8:20 a.m.-8:30 a.m. (pre-market ordering); 8:30 a.m.-2:55 p.m. (trading); 2:55 p.m.-3:00

Substantially all of the transactions on the Lima
Stock Exchange are traded on the electronic system. Transactions during the electronic sessions are executed through brokerage firms and stock brokers on behalf of their clients. Brokers submit orders in the order in which they are received. The
orders must specify the type of security as well as the amount and price of the proposed sale or purchase. In order to control price volatility, the Lima Stock Exchange imposes a 15-minute suspension on trading when the price of a security varies on
a single day by more than 15% for Peruvian companies and 30% for non-Peruvian companies.

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 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; (iii) local and international offerings, including simultaneous offerings; (iv) the Public Registry of Securities (the Registro
Público del Mercado de Valores); (v) reporting obligations of material information (hechos de importancia) by the issuers of securities recorded in the Public Registry of Securities and by the entities that are subject to the
regulation and supervision of the Peruvian Securities Commission; (vi) the enforcement of insider trading; (vii) privileged information and confidentiality regulations and prohibitions against price manipulation, (viii) the broker-dealers; (ix) the
Lima Stock Exchange; (x) CAVALI (the settlement and registry entity for transactions executed on the Lima Stock Exchange); (xi) other entities that are required to be registered at the Public Registry of Securities; (xii) capital market instruments
and operations, including securitizations; and (xiii) mutual funds and investments funds publicly placed and their respective management companies.

The Peruvian securities market is regulated and supervised by the Peruvian Securities Commission, 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.

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, 2015, we had 660,053,790 common shares outstanding. As of December 31, 2015, there were 1,819 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.

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.

##### Table of Contents

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.

##### Table of Contents

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.

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.

##### Table of Contents

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



193



---

##### Table of Contents

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 (a) holds
or has the power to exercise directly or indirectly 25%, 50% or 60% of the voting rights in a listed company, or (b) 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 (a) 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; (b) as a consequence of a public sale offer, or (c) 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: (a) shareholders
representing 100% of the voting rights consent in writing, (b) voting shares are acquired by a depositary in order to subsequently issue ADSs, or (c) voting shares are acquired pursuant to the exercise of preemptive rights.

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.



194



---

##### Table of Contents

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:

|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 has 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.

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 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 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. 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 entities resident in Peru are subject to Peruvian income tax on their
worldwide income while Non-Peruvian Holders are subject to Peruvian income tax only on their Peruvian source income.



196



---

##### Table of Contents

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 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 consummated 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 Law 30341, capital gains resulting from a transfer of common shares through the Lima Stock Exchange will be exempt of income tax, provided
that the following conditions are met: (i) in any 12 month period, neither the seller or any person related to him or her must dispose of more than 10% of the total number of common shares issued by the company, and (ii) the shares must have a
market presence, meaning that transactions in respect of those shares for a value exceeding 4 Tax Units (currently, PEN 15,800) shall have occurred in at least 27 business days out of any 180 business days period comprising 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.

Any Non-Peruvian Holder 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 such 30 day period, the tax basis calculation presented for
approval by the transferor is deemed automatically approved.

In any transaction relating to Peruvian securities through the Lima Stock
Exchange, CAVALI (the Peruvian clearing house) will act as withholding agent of the Peruvian income tax. If the purchaser is 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 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;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | an estate the income of which is subject to United States federal income taxation regardless of its source; or
| | - |  | --------------------------------------------------------------------------------------------------------------



| | ● |  | a trust if it (1) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust, or (2) has a valid
election in effect under applicable United States Treasury regulations to be treated as a United States person.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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:



| | ● |  | a dealer in securities or currencies;
| | - |  | -------------------------------------



| | ● |  | a financial institution;
| | - |  | ------------------------



| | ● |  | a regulated investment company;
| | - |  | -------------------------------



| | ● |  | a real estate investment trust;
| | - |  | -------------------------------



| | ● |  | an insurance company;
| | - |  | ---------------------



| | ● |  | a tax-exempt organization;
| | - |  | --------------------------



| | ● |  | a person holding our common shares or ADSs as part of a hedging, integrated or conversion transaction, a constructive sale or a straddle;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | a trader in securities that has elected the mark-to-market method of accounting for your securities;
| | - |  | ----------------------------------------------------------------------------------------------------



| | ● |  | a person liable for alternative minimum tax;
| | - |  | --------------------------------------------



| | ● |  | a person who owns or is deemed to own 10% or more of our voting stock;
| | - |  | ----------------------------------------------------------------------



| | ● |  | a partnership or other pass-through entity for United States federal income tax purposes; or

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.

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, will be listed on a securities market



199

##### Table of Contents

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 nuevos soles will equal the U.S. dollar value of the nuevos 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 nuevos soles are converted into U.S. dollars at
that time. If the nuevos 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 nuevos 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 nuevos 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 nuevos 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.

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.

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 file reports and other information with the SEC, including annual reports on Form 20-F and reports on Form 6-K. You may inspect and copy reports and other
information to be filed with 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
intend 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 will not be subject to Section 16 of the Exchange Act relating to insider short-swing profit disclosure and recovery regime.

##### Table of Contents

We will 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 will make all these notices, reports and communications
that it receives from us available for inspection by registered holders of ADSs at its office. The depositary will mail 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 will 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 5 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 nuevos soles, U.S. dollars, Chilean pesos and, to a lesser extent, other currencies. In 2015, 56.6%, 21.0% and 22.4%% of our revenues were denominated in nuevos soles, U.S. dollars and other currencies (principally
Chilean pesos), respectively, while 75.3%, 23.1% and 1.6% of our cost of sales during the year were denominated in nuevos soles, U.S. dollars and other currencies. In addition, as of December 31, 2015, 56.0%, 33.1% and 11.0% of our total debt was
denominated in nuevos soles, U.S. dollars and other currencies, respectively. If, at December 31, 2015, the nuevo 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/.1.7 million



202

##### Table of Contents

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, 2015, 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/.91.6 million annually. This
sensitivity analysis does not take into account indebtedness that we incur subsequent to December 31, 2015

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 2015. We do not have long-term contracts for the supply of these key inputs. Based upon our consumption of these inputs during 2015, a 10% increase/decrease in the prices of each of oil, steel and cement would
have increased/decreased our costs of sales by S/.75.4 million, S/.7.8 million and S/.1.8 million, respectively. However, based on our production of oil during 2015, a 10% increase/decrease in the price of oil would have increased/decreased our
revenues by S/.87.2 million.

General

JPMorgan Chase Bank, N.A., as depositary, has issued ADSs. Each ADS represents an ownership interest in five common shares deposited with the
custodian, Citibank del Perú S.A., as agent of the depositary, under the deposit agreement among us, the depositary and you as an ADS holder. In the future, each ADS will also represent any

##### Table of Contents

securities, cash or other property deposited with the depositary but which they have not distributed directly to you. Unless certificated ADRs are specifically requested by you, all ADSs will be
issued on the books of our depositary in book-entry form and periodic statements will be mailed to you which reflect your ownership interest in such ADSs. In this description, references to ADRs, shall include the statements you will receive which
reflect your ownership of ADSs.

The depositarys office is located at 1 Chase Plaza, Floor 58, New York, New York 10005-1401, United
States.

You may hold ADSs either directly or indirectly through your broker or other financial institution. If you hold ADSs directly, by
having an ADS registered in your name on the books of the depositary, you are an ADR holder. This description assumes you hold your ADSs directly. If you hold the ADSs through your broker or financial institution nominee, you must rely on the
procedures of such broker or financial institution to assert the rights of an ADR holder described in this section. You should consult with your broker or financial institution to find out what those procedures are.

As an ADR holder, we will not treat you as a shareholder of ours and you will not have any shareholder rights. Peruvian law governs
shareholder rights. ADR holders have no direct ownership interest in our common shares and only have such rights as specified in the deposit agreement. Your rights are those of an ADR holder. Such rights derive from the terms of the deposit
agreement entered into among us, the depositary and all registered holders from time to time of ADSs issued under the deposit agreement. The obligations of the depositary and its agents are also set out in the deposit agreement. Because the
depositary or its nominee are actually the registered owner of the common shares, you must rely on the depositary or its nominee to exercise the rights of a shareholder on your behalf. The deposit agreement and the ADSs are governed by the law of
the State of New York. However, our obligations to the holders of common shares represented by the ADSs are governed by the laws of Peru, which may be different from the law of the State of New York.

The following is a summary of what we believe to be the material terms of the deposit agreement. This summary is qualified in its entirety by

Dividends and Other Distributions

We may make various types of distributions with respect to our securities. The depositary has agreed that, to the extent practicable, it will
pay to you the cash dividends or other distributions it or the custodian receives on common shares or other deposited securities, after converting any cash received into U.S. dollars and, in all cases, making any necessary deductions provided for in
the deposit agreement. You will receive these distributions in proportion to the number of underlying securities that your ADSs represent.

Except as stated below, the depositary will deliver such distributions to ADR holders in proportion to their interests in the following
manner:

Distribution of Cash. The depositary will distribute any U.S. dollars available to it resulting from a cash dividend or
other cash distribution or the net proceeds of sales of any other distribution or portion thereof (to the extent applicable), on an averaged or other practicable basis, subject to (i) appropriate adjustments for taxes withheld, (ii) such
distribution being impermissible or impracticable with respect to certain registered ADR holders, and (iii) deduction of the depositarys and/or its agents expenses in (1) converting any foreign currency to U.S. dollars to the extent that
it determines that such conversion may be made on a reasonable basis, (2) transferring foreign currency or U.S. dollars to the United States by such means as the depositary may determine to the extent that it determines that such transfer may be
made on a reasonable basis, (3) obtaining any approval or license of any governmental authority required for such conversion or transfer, which is obtainable at a reasonable cost and within a reasonable time, and (4) making any sale by public or
private means in any commercially reasonable manner. If exchange rates fluctuate during a time when the depositary cannot convert a foreign currency, you may lose some or all of the value of the distribution.

Distribution of Common Shares. In the case of a distribution of common shares, the depositary will issue additional ADRs to evidence
the number of ADSs representing such common shares. Only whole ADSs will be issued. Any common shares which would result in fractional ADSs will be sold and the net proceeds will be distributed in the same manner as cash to the ADR holders entitled
thereto.

No distribution of ADRs as described above will be made if it violates U.S. securities laws, or any other law, or if it is not
operationally practicable. If the depositary does not distribute new ADRs as described above, it will use its best efforts to sell the common shares received and distribute the proceeds of the sale in the same manner as a cash distribution.

Rights to Receive Additional Common Shares. In the case of a distribution of



205



---

##### Table of Contents

rights to subscribe for additional common shares or other rights, if we provide evidence satisfactory to the depositary that it may lawfully distribute such rights, the depositary will distribute
warrants or other instruments in the discretion of the depositary representing such rights. If we do not furnish such evidence, the depositary may:



| | ● |  | sell such rights if practicable and distribute the net proceeds in the same manner as cash distributions to the ADR holders entitled thereto; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | if the sale of such rights cannot practicably be accomplished by reason of the non-transferability of the rights, limited markets therefor, their short duration or otherwise, do nothing and allow such rights to lapse,
in which case ADR holders will receive nothing.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Other Distributions. In the case of a distribution of securities or
property other than those described above, the depositary may either (i) distribute such securities or property in any manner it deems equitable and practicable or (ii) to the extent the depositary deems distribution of such securities or property
not to be equitable and practicable, sell such securities or property and distribute any net proceeds in the same manner it distributes cash. If the depositary determines that any distribution described above is not practicable with respect to any
specific registered ADR holder, the depositary may choose any method of distribution that it deems practicable for such ADR holder, including the distribution of foreign currency, securities or property, or it may retain such items, without paying
interest on or investing them, on behalf of the ADR holder as deposited securities, in which case the ADSs will also represent the retained items.

U.S. dollars will be distributed by checks drawn on a bank in the United States for whole U.S. dollars and cents. Fractional cents will be
withheld without liability and dealt with by the depositary in accordance with its then current practices.

We have no obligation to file
a registration statement under the Securities Act in order to make any rights, securities or other property available to ADR holders.

The
depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADR holders.

The
depositary may use a division, branch or affiliate of JPMorgan Chase Bank, N.A. to direct manage and/ or execute any public and/or private sale of securities.

There can be no assurance that the depositary will be able to convert any currency at a specified exchange rate or sell any property, rights,
common shares or other securities at a specified price, nor that any of such transactions can be completed within a specified time period.

Issuance of
ADSs upon Deposit of Common Shares

The depositary will issue ADSs if you or your broker deposit common shares or evidence of rights
to receive common shares with the custodian and pay the fees and expenses owing to the depositary in connection with such issuance.

Common shares deposited in the future with the custodian must be accompanied by the delivery of certain documentation and shall, at the time
of such deposit, be registered in the name of JPMorgan Chase Bank, N.A., as depositary for the benefit of holders of ADRs or in such other name as the depositary shall direct.

The custodian will hold all deposited common shares for the account of the depositary. ADR holders thus have no direct ownership interest in
our common shares and only have such rights as are contained in the deposit agreement. The custodian will also hold any additional securities, property and cash received on or in substitution for the deposited common shares. The deposited common
shares and any such additional items are referred to as deposited securities.



206



---

##### Table of Contents

Upon each deposit of common shares, receipt of related documentation and compliance with the
other provisions of the deposit agreement, including the payment of the fees and charges of the depositary and any taxes or other fees or charges owing, the depositary will issue an ADR or ADRs in the name or upon the order of the person entitled
thereto evidencing the number of ADSs to which such person is entitled. All of the ADSs issued will, unless specifically requested to the contrary, be part of the depositarys direct registration system, and a registered holder will receive
periodic statements from the depositary which will show the number of ADSs registered in such holders name. An ADR holder can request that the ADSs not be held through the depositarys direct registration system and that a certificated
ADR be issued.

The term common shares in this section shall also refer to preliminary stock certificates (certificados
provisionales), which will be converted to common shares once the capital increase is registered with the Peruvian public registry and new common shares are listed on the Lima Stock Exchange and registered in the CAVALI S.A. ICLV book-entry
settlement system.

Withdrawal of Common Shares upon Cancellation of ADSs

When you turn in your ADR certificate at the depositarys office, or when you provide proper instructions and documentation in the case
of direct registration ADSs, the depositary will, upon payment of certain applicable fees, charges and taxes, deliver the underlying common shares to you upon your written order. Delivery of common shares in certificated form will be made at the
custodians office. At your risk, expense and request, the depositary may deliver deposited securities at such other place as you may request.

The depositary may only restrict the withdrawal of deposited securities in connection with:



| | ● |  | temporary delays caused by closing our transfer books or those of the depositary or the deposit of common shares in connection with voting at a shareholders meeting, or the payment of dividends;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | the payment of fees, taxes and similar charges; or
| | - |  | --------------------------------------------------



| | ● |  | compliance with any Peruvian, U.S. or other foreign laws or governmental regulations relating to the ADRs or to the withdrawal of deposited securities.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------

Notwithstanding the foregoing, no withdrawal of deposited securities shall be permitted until the preliminary stock certificates
(certificados provisionales) have been converted to common shares once the capital increase has been recorded with the Peruvian public registry.

This right of withdrawal may not be limited by any other provision of the deposit agreement.

Record Dates

The depositary may, after
consultation with us if practicable, fix record dates for the determination of the registered ADR holders who will be entitled (or obligated, as the case may be) to:



| | ● |  | receive any distribution on or in respect of common shares;
| | - |  | -----------------------------------------------------------



| | ● |  | give instructions for the exercise of voting rights at a meeting of holders of common shares;
| | - |  | ---------------------------------------------------------------------------------------------



| | ● |  | pay the fee assessed by the depositary for administration of the ADR program and for any expenses as provided for in the ADR; or
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| | ● |  | receive any notice or to act in respect of any other matter, in each case, subject to the provisions of the deposit agreement.

Voting Rights

A holder of an ADR representing common shares will generally have the right under the deposit agreement to instruct the depositary to exercise
the voting rights for the underlying common shares represented by such ADRs. The voting rights of holders of common shares are described under Description of our Share Capital.

If you are an ADR holder and the depositary asks you to provide it with voting instructions, you may instruct the depositary how to exercise
the voting rights for the common shares which underlie your ADSs. As soon as practicable after receiving notice of any meeting or solicitation of consents or proxies from us, the depositary will distribute to the registered ADR holders a notice
stating such information as is contained in the voting materials received by the depositary and describing how you may instruct the depositary to exercise the voting rights for the common shares which underlie your ADSs, including instructions for
giving a discretionary proxy to a person designated by us. For instructions to be valid, the depositary must receive them in the manner and on or before the date specified. The depositary will try, as far as is practical, subject to the provisions
of and governing the underlying common shares or other deposited securities and Peruvian law, to vote or to have its agents vote the common shares or other deposited securities as you instruct. The depositary will only vote or attempt to vote as you
instruct. The depositary will not itself exercise any voting discretion. Furthermore, neither the depositary, nor its agents, are responsible for any failure to carry out any voting instructions, for the manner in which any vote is cast or for the
effect of any vote, other than for failure caused directly by gross negligence, bad faith or willful misconduct on the part of the depositary or its agents. Notwithstanding anything contained in the deposit agreement or any ADR, the depositary may,
to the extent not prohibited by law or applicable regulations, or by the requirements of the stock exchange on which the ADSs are listed, in lieu of distribution of the materials provided to the depositary in connection with any meeting of, or
solicitation of consents or proxies from, holders of deposited securities, distribute to the registered holders of ADRs a notice that provides such holders with, or otherwise publicizes to such holders, instructions on how to retrieve such materials
or receive such materials upon request (i.e., by reference to a website containing the materials for retrieval or a contact for requesting copies of the materials).

There is no assurance that you will receive voting materials in time to instruct the depositary to vote and it is possible that you, or
persons who hold their ADSs through brokers, dealers or other third parties, will not have the opportunity to exercise a right to vote.

Reports and
Other Communications

The depositary will make available for inspection by ADR holders at the offices of the depositary and the
custodian the deposit agreement, the provisions of or governing deposited securities, and any written communications from us which are both received by the custodian or its nominee as a holder of deposited securities and made generally available to
the holders of deposited securities.

Additionally, if we make any written communications generally available to holders of our common
shares, and we furnish copies thereof (or English translations or summaries) to the depositary, it will distribute the same to registered ADR holders.

Fees and Expenses

The depositary may
charge each person to whom ADSs are issued, including, without limitation, issuances against deposits of common shares, issuances in respect of common share distributions, rights and other distributions, issuances pursuant to a stock dividend or
stock split declared by us or issuances pursuant to a merger, exchange of securities or any other transaction or event affecting the ADSs or deposited securities, and each person surrendering ADSs for withdrawal of deposited securities or whose ADRs
are cancelled or reduced for any other reason, US$5.00 or less for each 100 ADSs (or any portion thereof) issued, delivered, reduced, cancelled or surrendered, as the case may be. The depositary may sell (by public or private sale) sufficient
securities and property received in respect of a common share distribution, rights and/or other distribution prior to such deposit to pay such charge.

##### Table of Contents

The following additional charges shall be incurred by the ADR holders, by any party depositing or
withdrawing common shares or by any party surrendering ADSs or to whom ADSs are issued (including, without limitation, issuance pursuant to a stock dividend or stock split declared by us or an exchange of stock regarding the ADRs or the deposited
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);
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | a fee for the distribution or sale of securities pursuant to paragraph 10 of the deposit agreement, such fee being in an amount equal to the US$0.05 per ADS issuance fee for the execution and delivery of ADSs which
would have been charged as a result of the deposit of such securities (treating all such securities as if they were common shares) but which securities or the net cash proceeds from the sale thereof are instead distributed by the depositary to those
holders entitled thereto;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | stock transfer or other taxes and other governmental charges;
| | - |  | -------------------------------------------------------------



| | ● |  | cable and facsimile transmission and delivery charges incurred at your request in connection with the deposit or delivery of common shares;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | transfer or registration fees for the registration of transfer of deposited securities on any applicable register in connection with the deposit or withdrawal of deposited securities; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | 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 2015, the depositary reimbursed us for expenses in an aggregate amount of US$88,219.

Payment of Taxes

ADS holders or ADR
holders, as the case may be, must pay any tax or other governmental charge (including any penalties and/or interest) payable by the custodian or the depositary on any ADS or ADR, deposited security or distribution. By holding or having held an ADS
or an ADR, as the case be, the holders agree to indemnify, defend and save harmless each of the depositary and its agents in respect thereof. If an ADS holder or ADR holder, as the case may be, owes any tax or other governmental charge, the
depositary may (i) deduct the amount thereof from any cash distributions, or (ii) sell deposited securities (by public or private sale) and deduct the amount owing from the net proceeds of such sale. In either case the ADS holder or ADR holder, as
the case may be, remains liable for any shortfall. If any tax or governmental charge is unpaid, the depositary may also refuse to effect any registration, registration of transfer, split up or combination of deposited securities or withdrawal of
deposited securities until such payment is made. If any tax or governmental charge is required to be withheld on any cash distribution, the depositary may deduct the amount required to be withheld from any cash distribution or, in the case of a
non-cash distribution, sell the distributed property or securities (by public or private sale) to pay such taxes and distribute any remaining net proceeds to the ADS holders or the ADR holders entitled thereto.

By holding an ADR or an ADS, as the case may be, or an interest therein, you will be agreeing to indemnify us, the depositary, the custodian
and any of our or their respective directors, employees, agents and affiliates against, and hold each of them harmless from, any claims by any governmental authority with respect to taxes, additions to tax, penalties or interest arising out of any
refund of taxes, reduced rate of withholding at source or other tax benefit obtained.

Reclassifications, Recapitalizations and Mergers

If we take certain actions that affect the deposited securities, including (i) any change in par value, split up, consolidation, cancellation
or other reclassification of deposited securities or (ii) any distributions not made to holders of ADRs or (iii) any recapitalization, reorganization, merger, consolidation, liquidation, receivership, bankruptcy or sale of all or substantially all
of our assets, then the depositary may choose to:



| | ● |  | amend the form of ADR;
| | - |  | ----------------------



| | ● |  | distribute additional or amended ADRs;
| | - |  | --------------------------------------



| | ● |  | distribute cash, securities or other property it has received in connection with such actions;
| | - |  | ----------------------------------------------------------------------------------------------



| | ● |  | sell any securities or property received and distribute the proceeds as cash; or
| | - |  | --------------------------------------------------------------------------------



| | ● |  | none of the above.
| | - |  | ------------------

If the depositary does not choose any of the above options, any of the
cash, securities or other property it receives will constitute part of the deposited securities and each ADS will then represent a proportionate interest in such property.

##### Table of Contents

Amendment and Termination

We may agree with the depositary to amend the deposit agreement and the ADSs without your consent for any reason. ADR holders must be given at
least 30 days notice of any amendment that imposes or increases any fees or charges (other than stock transfer or other taxes and other governmental charges, transfer or registration fees, cable, telex or facsimile transmission costs, delivery
costs or other such expenses), or otherwise prejudices any substantial existing right of ADR holders. Such notice need not describe in detail the specific amendments effectuated thereby, but must give ADR holders a means to access the text of such
amendment. If an ADR holder continues to hold an ADR or ADRs after being so notified, such ADR holder is deemed to agree to such amendment and to be bound by the deposit agreement as so amended. Notwithstanding the foregoing, if any governmental
body or regulatory body should adopt new laws, rules or regulations which would require amendment or supplement of the deposit agreement or the form of ADR to ensure compliance therewith, we and the depositary may amend or supplement the deposit
agreement and the ADR at any time in accordance with such changed laws, rules or regulations, which amendment or supplement may take effect before a notice is given or within any other period of time as required for compliance. No amendment,
however, will impair your right to surrender your ADSs and receive the underlying securities, except in order to comply with mandatory provisions of applicable law.

The depositary may, and shall at our written direction, terminate the deposit agreement and the ADRs by mailing notice of such termination to
the registered holders of ADRs at least 30 days prior to the date fixed in such notice for such termination; provided, however, if the depositary shall have (1) resigned as depositary under the deposit agreement, notice of such termination by the
depositary shall not be provided to registered holders unless a successor depositary shall not be operating under the deposit agreement within 60 days of the date of such resignation, and (2) been removed as depositary under the deposit agreement,
notice of such termination by the depositary shall not be provided to registered holders of ADRs unless a successor depositary shall not be operating under the deposit agreement on the 60th day after our notice of removal was first provided to the
depositary. After termination, the depositarys only responsibility will be (1) to deliver deposited securities to ADR holders who surrender their ADRs, and (2) to hold or sell distributions received on deposited securities. As soon as
practicable after the expiration of six months from the termination date, the depositary will sell the deposited securities which remain and hold the net proceeds of such sales (as long as it may lawfully do so), without liability for interest, in
trust for the ADR holders who have not yet surrendered their ADRs. After making such sale, the depositary shall have no obligations except to account for such proceeds and other cash.

Limitations on Obligations and Liability to ADR Holders

Prior to the issue, registration, registration of transfer, split-up, combination, or cancellation of any ADRs, or the delivery of any
distribution in respect thereof, and from time to time, we or the depositary or the custodian may require:



| | ● |  | payment with respect thereto of (i) any stock transfer or other tax or other governmental charge, (ii) any stock transfer or registration fees in effect for the registration of transfers of common shares or other
deposited securities upon any applicable register and (iii) any applicable fees and expenses described in the deposit agreement;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | the production of proof satisfactory to it of (i) the identity of any signatory and genuineness of any signature and (ii) such other information, including without limitation, information as to citizenship, residence,
exchange control approval, beneficial ownership of any securities, compliance with applicable law, regulations, provisions of or governing deposited securities and terms of the deposit agreement and the ADRs, as it may deem necessary or proper; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | compliance with such regulations as the depositary may establish consistent with the deposit agreement.

The issuance of ADRs, the acceptance of deposits of common shares, the registration, registration
of transfer, split-up or combination of ADRs or the withdrawal of common shares, may be suspended, generally or in particular instances, when the ADR register or any register for deposited securities is closed or when any such action is deemed
advisable by the depositary or when reasonably requested by us in order to enable us to comply with applicable law; provided that the ability to withdraw common shares may only be limited under the following circumstances: (i) temporary delays
caused by closing transfer books of the depositary or our transfer books or the deposit of common shares in connection with voting at a shareholders meeting, or the payment of dividends, (ii) the payment of fees, taxes, and similar charges,
and (iii) compliance with any laws or governmental regulations relating to ADRs or to the withdrawal of deposited securities.

The deposit
agreement expressly limits the obligations and liability of the depositary, ourselves and our respective agents. Neither we nor the depositary nor any such agent will be liable if:



| | ● |  | any present or future law, rule, regulation, fiat, order or decree of the United States, Peru or any other country, or of any governmental or regulatory authority or securities exchange or market or automated quotation
system, the provisions of or governing any deposited securities, any present or future provision of our charter, any act of God, war, terrorism, nationalization, expropriation, currency restrictions, work stoppage, strike, civil unrest, revolutions,
rebellions, explosions, computer failure or other circumstance beyond our, the depositarys or our respective agents control shall prevent or delay, or shall cause any of them to be subject to any civil or criminal penalty in connection
with, any act which the deposit agreement or the ADRs provide shall be done or performed by us, the depositary or our respective agents (including, without limitation, voting);

practicable;

| | ● |  | it performs its obligations under the deposit agreement and ADRs issued thereunder without gross negligence, bad faith or willful misconduct;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | it takes any action or refrains from taking any action in reliance upon the advice of or information from legal counsel, accountants, any person presenting common shares for deposit, any registered holder of ADRs, or
any other person believed by it to be competent to give such advice or information; or

Neither the depositary nor its agents have any obligation to appear in, prosecute or defend any action, suit or other proceeding in respect of
any deposited securities or the ADRs. We and our agents shall only be obligated to appear in, prosecute or defend any action, suit or other proceeding in respect of any deposited securities or the ADRs, which in our opinion may involve us in expense
or liability, if indemnity satisfactory to us against all expense (including fees and disbursements of counsel) and liability is furnished as often as may be required. The depositary and its agents may fully respond to any and all demands or
requests for information maintained by or on its behalf in connection with the deposit agreement, any registered holder or holders of ADRs, any ADRs or otherwise related to the deposit agreement or ADRs to the extent such information is requested or
required by or pursuant to any lawful authority, including, without limitation, laws, rules, regulations, administrative or judicial processes, banking, securities or other regulators. The depositary shall not be liable for the acts or omissions
made by, or the insolvency of any securities depository, clearing agency or settlement system in connection with or arising out of book-entry settlement of deposited securities or otherwise. Furthermore, the depositary shall not be responsible for,
and shall incur no liability in connection with or arising from, the insolvency of any custodian that is not a branch or affiliate of JPMorgan Chase Bank, N.A. The depositary and the custodian may use third party delivery services and providers of
information regarding matters such as pricing, proxy voting, corporate actions, class action litigation and other services in connection with the ADRs and the deposit agreement, and use local agents to provide extraordinary services such as
attendance at annual meetings of issuers of securities. The

depositary and the custodian are required to use reasonable care in the selection and retention of such third party providers and local agents, but neither the depositary nor the custodian will
be responsible for any error or omissions made by such third party providers or local agents in providing the relevant information or services. The depositary shall not be responsible for, and shall incur no liability in connection with or arising
from, any act or omission to act on the part of the custodian except to the extent that (A) the custodian has been determined by a final non-appealable judgment of a court of competent jurisdiction to have (i) committed fraud or willful misconduct
in the provision of custodial services to the depositary or (ii) failed to use reasonable care in the provision of custodial services to the depositary as determined in accordance with the standards prevailing in the jurisdiction in which the
custodian is located and (B) we or the registered holders of ADRs have incurred direct damages as a result of such act or omission to get on the part of the custodian.

The depositary shall be under no obligation to inform holders of ADSs regarding the requirements of Peruvian law, rules or regulations or any
changes therein or thereunder.

Additionally, none of us, the depositary or the custodian will be liable for the failure by any registered
holder of ADRs or beneficial owner therein to obtain the benefits of credits on the basis of non-U.S. tax paid against such holders or beneficial owners income tax liability. Neither we nor the depositary shall incur any liability for
any tax consequences that may be incurred by holders or beneficial owners on account of their ownership of ADRs or ADSs.

The depositary
shall not incur any liability for the content of any information submitted to it by us or on our behalf for distribution to the holders of ADRs or for any inaccuracy of any translation thereof, for any investment risk associated with acquiring an
interest in the deposited securities, for the validity or worth of the deposited securities, for the credit-worthiness of any third party, for allowing any rights to lapse upon the terms of the deposit agreement or for the failure or timeliness of
any notice from us. Further, the depositary shall not have any liability for the price received in connection with any sale of securities or the timing thereof.

Neither the depositary nor its agents will be responsible for any failure to carry out any instructions to vote any of the deposited
securities, for the manner in which any such vote is cast or for the effect of any such vote. None of us, the depositary, or our agents shall be liable to registered holders of ADRs or beneficial owners of interests in ADSs for any indirect,
special, punitive or consequential damages (including, without limitation, lost profits) of any form incurred by any person or entity, whether or not foreseeable and regardless of the type of action in which such a claim may be brought.

The depositary shall not be liable for any acts or omissions made by a successor depositary whether in connection with a previous act or
omission of the depositary or in connection with any matter arising wholly after the removal or resignation of the depositary, provided that in connection with the issue out of which such potential liability arises the depositary performed its
obligations without negligence while it acted as depositary.

In the deposit agreement each party thereto (including, for avoidance of
doubt, each holder and beneficial owner and/or holder of interests in ADRs) irrevocably waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in any suit, action or proceeding against the depositary
and/or us directly or indirectly arising out of or relating to the common shares or other deposited securities, the ADSs or the ADRs, the deposit agreement or any transaction contemplated therein, or the breach thereof (whether based on contract,
tort, or common law or any other theory).

The depositary may rely upon instructions from us or our counsel in respect of any governmental
or agency approval or license required for any currency conversion, transfer or distribution.

The depositary may own and deal in any
class of our securities and in ADSs.

Disclosure of Interest in ADSs

To the extent that the provisions of, or governing, any deposited securities may require disclosure of or impose limits on beneficial or other
ownership of deposited securities, other common shares and other securities and may provide for blocking transfer, voting or other rights to enforce such disclosure or limits, you agree to comply with all such disclosure requirements and ownership
limitations and to comply with any reasonable instructions we may provide in respect thereof. We reserve the right to instruct you to deliver your ADSs for cancellation and withdrawal of the deposited securities so as to permit us to deal with you
directly as a holder of common shares and, by holding an ADS or an interest therein, you will be agreeing to comply with such instructions.

Books of
Depositary

The depositary or its agent will maintain a register for the registration, registration of transfer, combination and
split-up of ADRs, which register shall include the depositarys direct registration system. Registered holders of ADRs may inspect such records at the depositarys office at all reasonable times, but solely for the purpose of communicating
with other holders in the interest of the business of our company or a matter relating to the deposit agreement. Such register may be closed from time to time, when deemed expedient by the depositary.

The depositary will maintain facilities for the delivery and receipt of ADRs.

Pre-Release of ADSs

In its capacity as
depositary, the depositary shall not lend common shares or ADSs; provided, however, that the depositary may (i) issue ADSs prior to the receipt of common shares and (ii) deliver common shares prior to the receipt of ADSs for withdrawal of deposited
securities, including ADSs which were issued under (i) above but for which common shares may not have been received (each such transaction a prerelease). The depositary may receive ADSs in lieu of common shares under (i) above (which
ADSs will promptly be canceled by the depositary upon receipt by the depositary) and receive common shares in lieu of ADSs under (ii) above. Each such pre-release will be subject to a written agreement whereby the person or entity (the
applicant) to whom ADSs or common shares are to be delivered (1) represents that at the time of the pre-release the applicant or its customer owns the common shares or ADSs that are to be delivered by the applicant under such
pre-release, (2) agrees to indicate the depositary as owner of such common shares or ADSs in its records and to hold such common shares or ADSs in trust for the depositary until such common shares or ADSs are delivered to the depositary or the
custodian, (3) unconditionally guarantees to deliver to the depositary or the custodian, as applicable, such common shares or ADSs, and (4) agrees to any additional restrictions or requirements that the depositary deems appropriate. Each such
pre-release will be at all times fully collateralized with cash, U.S. government securities or such other collateral as the depositary deems appropriate, terminable by the depositary on not more than five business days notice and subject to
such further indemnities and credit regulations as the depositary deems appropriate. The depositary will normally limit the number of ADSs and common shares involved in such pre-release at any one time to 30% of the ADSs outstanding (without giving
effect to ADSs outstanding under (i) above), provided, however, that the depositary reserves the right to change or disregard such limit from time to time as it deems appropriate. The depositary may also set limits with respect to the number of ADSs
and common shares involved in pre-release with any one person on a case-by-case basis as it deems appropriate. The depositary may retain for its own account any compensation received by it in conjunction with the foregoing. Collateral provided in
connection with pre-release transactions, but not the earnings thereon, shall be held for the benefit of the registered holders of ADRs (other than the applicant).

Appointment

In the deposit agreement,
each registered holder of ADRs and each person holding an interest in ADSs, upon acceptance of any ADSs (or any interest therein) issued in accordance with the terms and conditions of the deposit agreement will be deemed for all purposes to:



| | ● |  | be a party to and bound by the terms of the deposit agreement and the applicable ADR or ADRs; and
| | - |  | -------------------------------------------------------------------------------------------------



| | ● |  | appoint the depositary as its attorney-in-fact, with full power to delegate, to act on its behalf and to take any

Governing Law

The deposit agreement and
the ADRs are governed by and construed in accordance with the laws of the State of New York. In the deposit agreement, we have submitted to the jurisdiction of the courts of the State of New York and appointed an agent for service of process on our
behalf. By holding an ADS or an interest therein, registered holders of ADRs and beneficial owners of ADSs each irrevocably agree that any legal suit, action or proceeding against or involving us or the depositary, arising out of or based upon the
deposit agreement or the transactions contemplated thereby, may only be instituted in a state or federal court in New York, New York, and each irrevocably submits to the exclusive jurisdiction of such courts in any such suit, action or proceeding.

Use of Proceeds

On July 23 and 24,
2013, the Registration Statements on Form F-1 (File No. 333-189067) filed by us with the SEC covering the initial public offering in the United States of up to 22,465,117 ADSs, representing 112,325,585 common shares, were declared effective. 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, through a syndicate of underwriters led by Credit Suisse Securities (USA) LLC, J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC and BTG Pactual S.A.  Cayman Branch, as joint book-running managers.
BBVA Banco Continental, BCP Capital Financial Services S.A. and Banco Internacional del Perú  Interbank acted as co-managers.

We received approximately US$411.3 million in net proceeds from our initial public offering of ADSs in the United States. These proceeds have,
consistent with our disclosure in the Registration Statement, been used as follows: in the Infrastructure segment, the purchase of trains for Line 1 of the Lima Metro (US$178.4 million), the purchase of an additional stake of Norvial (US$18.6
million), the purchase of an additional stake in TGP (US$20 million), an investment in COGA (US$ 25.3 million), the initial equity investment in Via Expresa Sur (US$10 million) and the equity contribution of GSP (US$ 65.3 million); in the Real
Estate segment, the purchase of land (US$15.2 million); and in the E&C segment the acquisition of Morelco in Colombia (US$78.5 million).

We expect to use the remaining net proceeds from the offering for capital expenditures, including potential investments and acquisitions, and
other general corporate purposes in our business segments, in order to take advantage of growth opportunities that we foresee in our markets.

|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, 2015, our disclosure
controls and procedures were not effective as a result of the material weakness in internal control 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, management has conducted an assessment, including
testing, using the 1992 criteria in Internal Control-Integrated Framework, 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 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 internal
controls over financial reporting as of December 31, 2015, we determined that a control deficiency existed that constituted a material weakness, as a result of inadequate controls over segregation of duties in certain activities within four of our
subsidiaries, namely, Survial, GMP, GYM Ferrovias and Vial y Vives. In particular, certain persons at such subsidiaries had access to conduct conflicting accounting operations, which would be against our accounting policies. The internal controls we
had in place to detect these conflicts in our segregation of duties failed, because we failed to gather all of the applicable information, as a consequence of the process of information gathering being conducted manually. 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.

As a result of the material weakness described above, management has concluded that we did not maintain effective internal
control over financial reporting as of December 31, 2015, based on the 1992 criteria in Internal Control-Integrated Framework, issued by the COSO.

Management has concluded that, regardless of the material weakness described above, the financial statements fairly present, in all material
respects, our financial condition, results of operations and cash flows for the periods presented in this report.

We continue to evaluate
our internal control over financial reporting and are taking remedial actions to address the material weakness that has been identified. To this end, in particular, we are in the process of reviewing our employees access throughout our
accounting systems. We also plan to deploy new information technology tools in order to improve our control over the segregation of accounting duties. We are particularly focused on activities that are currently undertaken manually. Furthermore,
moving forward, we will continue to monitor and assess our remediation activities to address the material weakness discussed above through remediation as soon as practicable.

The implementation of these measures may not fully address the existing material weakness in our internal control over financial reporting and
we cannot yet conclude that it has been, nor can we ensure by what date it 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.D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. 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.

Gaveglio, Aparicio y Asociados S.C. de R.L., a member of PricewaterhouseCoopers, an independent registered public accounting firm, which has
audited and reported on the consolidated financial statements contained in this annual report on Form 20-F, has issued an attestation report on managements assessment of our internal control over financial reporting.

during the year ended December 31, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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 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, however we do have a majority of independent directors in our board. Additionally, our Audit and Process Committee is comprised completely of independent directors, while our Investment and Risk Committee is
comprised by a majority of independent 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 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.

##### Table of Contents

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 OFINDEPENDENTREGISTEREDPUBLICACCOUNTINGFIRM

To Graña y Montero S.A.A. Board of Directors and Shareholders

In our opinion, the accompanying consolidated statements of financial position and the related consolidated statements of income and other comprehensive
income, of changes in shareholders equity and of cash flows present fairly, in all material respects, the financial position of Graña y Montero S.A.A. and its subsidiaries at December 31, 2015 and 2014, and the results of their
operations and their cash flows for each of the three years in the period ended December 31, 2015 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, based on criteria established in Internal Control - Integrated Framework (1992) issued by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO) because a material weakness in internal control over financial reporting related to inadequate controls over segregation of duties in certain activities in some subsidiaries
existed as of that date. 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 weakness referred to above is described in Managements Annual Report on Internal Control over Financial Reporting appearing under Item 15 of this Annual Report on
Form 20F. We considered this material weakness in determining the nature, timing, and extent of audit tests applied in our audit of the December 31, 2015 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. 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 managements report 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 integrated audits (which were integrated audits in 2015 and 2014). We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board
(United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was
maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant
estimates made by management, and evaluating the overall financial statement presentation. 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.

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.

|1 | GENERAL INFORMATION
|- | -------------------

|2 | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
|- | ------------------------------------------

The principal accounting policies applied
in the preparation of these consolidated financial statements are set out below. These policies have been consistently applied to all the years presented, unless otherwise stated.



| | 2.1 | Basis of preparation -
| | --- | ----------------------

The consolidated financial statements of the Company have been
prepared in accordance with International Financial Reporting Standards (IFRS) and interpretations issued by the IFRS Interpretations Committee (IFRIC) applicable to companies reporting under IFRS. The financial statements comply with IFRS as issued
by the IASB.

The consolidated financial statements have been prepared under the historical cost convention, except for derivative
financial instruments, financial assets at fair value through profit and loss, available-for-sale financial assets measured at fair value and liabilities for a put option and pension plans that are measured at fair value. The financial statements
are presented in thousands of Peruvian Soles, unless otherwise stated.

The preparation of the consolidated financial statements in
conformity with IFRS requires the use of certain critical accounting estimates. It also requires Management to exercise its judgment in the process of applying the Groups accounting policies. The areas involving a higher degree of judgment or
complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in Note 4.



| | 2.2 | Consolidation of financial statements -
| | --- | ---------------------------------------



| | a) | Subsidiaries -
| | -- | --------------

Subsidiaries are all entities over which the Group has control. The Group
controls an entity when the group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. 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. The consideration transferred for the acquisition of a subsidiary is the fair value of the assets transferred, the liabilities assumed to the former owners of the acquiree and the equity
instruments issued by the Group. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement in favor of the selling party. Identifiable assets acquired,liabilities and
contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date.

The Group
assesses the measurement of any non-controlling interest in the acquiree on an acquisition-by-acquisition basis, either at fair value or at the non-controlling interests proportionate share of the recognized amounts of the acquirers
identifiable net assets or the fair value of the shares held by non-controlling shareholders. At December 31, 2015 and 2014 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.

Acquisition-related costs
are expensed as incurred.

If the business combination is achieved in stages, the carrying amount of the acquirers previously held
equity interest in the acquiree is re-measured to fair value at the acquisition date; any gains or losses arising from such re-measurement are recognized in profit or loss.

(All amounts expressed in thousands of S/ unless otherwise stated)



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 either in 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 as a bargain purchase 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, that is, as transactions with the 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 to 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 have 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 other comprehensive income. When the Groups share of losses in a joint venture equals or exceeds its interests in the joint ventures (which includes any long-term
interests that, in substance, form part of the groups net investment in the joint ventures), the Group does not recognize further losses, unless it has incurred obligations or made payments on behalf of the joint ventures. The Group investment
includes identified goodwill in its acquisition.

(All amounts expressed in thousands of S/ unless otherwise stated)



Unrealized gains on transactions between the Group and its joint ventures are eliminated to
the extent of the Groups interest in the joint ventures. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of the joint ventures have been changed
where necessary to ensure consistency with the policies adopted by the Group.

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 operation is a joint arrangement whereby the parties that have joint control of the arrangement, have rights to the assets, and
obligations for the liabilities, relating to the arrangement. Each party recognizes its assets, liabilities, revenue and expenses and its share of any asset and liability jointly held and of any revenue or expense arisen from the joint operation.



| | 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 above section d).

If ownership interest in an associate is reduced but significant influence is retained, only a proportionate share of the amounts previously
recognized in other comprehensive income is reclassified to profit or loss, where appropriate. The Groups share of post-acquisition profit or loss is recognized in profit or loss, and its share of post-acquisition movements in profit or loss
is recognized in other comprehensive income with a corresponding adjustment to the cost of the investment. When the Groups share of losses in an associate equals or exceeds its interest in the associate, including any other unsecured
receivables, the Group does not recognize further losses, unless it has incurred legal or assumed obligations or made payments on behalf of the associate.

Profits and losses resulting from upstream and downstream 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.

Dilution gains and losses arising in
investments in associates are recognized in profit or loss.

Impairment losses are measured and recorded in accordance with section d)
above.



| | 2.3 | Segment reporting -
| | --- | -------------------

Operating segments are reported in a manner consistent with the
internal reporting provided to the chief operating decision-maker 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 -
| | -- | --------------------------------------

Items included in the financial statements of each of
the Groups entities are measured using the currency of the primary economic environment in which each entity operates (the functional 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 prevailing 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 and from the changes at year-end exchange
rates of monetary assets and liabilities denominated in foreign currencies are recognized in the income statement, except when deferred in equity as qualifying cash flow hedges.

Foreign exchange gains and losses of all monetary items are presented in the income statement within financial expenses and financial income.



| | 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 the financial position presented are translated using the closing rate at the date of the 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 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 resulting exchange differences are recognized as separate components in other comprehensive income.
| | --- | -------------------------------------------------------------------------------------------------------

Goodwill and fair value adjustments arising because of 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 arising are recognized in other comprehensive income.

Exchange differences arising on loans from the Parent 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 qualifying as part of the net investment of the foreign operation.

| | 2.5 | Public services concession agreements -
| | --- | ---------------------------------------

Concession agreements signed between the Group
and the Peruvian Government entitles the Group, as a Concessionaire, to assume obligations for the construction or improvement of infrastructure and which qualify as public service concessions 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), as set forth below.

Under these agreements (the grantor), the government controls and regulates services provided by the Group with the infrastructure and
dictates to whom it must provide them and at what price. The concession agreement establishes the obligation for the Group to return the infrastructure to the grantor at the end of the concession period or when there is an expiration event.

This feature gives the grantor control of the risks and rewards of the residual value of the assets at the end of the concession period. For
this reason, the Group will not recognize the infrastructure as part of its property, plant and equipment.

The Group manages three types
of concessions which accounting recognition is as follows:



| | a) | Recognizes a financial asset to the extent that it has a contractual right to receive cash or another 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 statement of 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 financial statements, bank overdrafts are included in the balance of
financial obligations as current liabilities in the statement of financial position.



| | 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 financial statements, the Group has classified its financial assets in the following three categories:



| | a) | Financial assets at fair value through profit or loss -
| | -- | -------------------------------------------------------



F-14



---

##### Table of Contents

(All amounts expressed in thousands of S/ unless otherwise stated)



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. The changes in their fair value are recognized in profit or loss in item Other income and expenses, net in the income
statement.



| | 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 which maturity is greater than 12 months after the statement of financial position. These are classified as
non-current assets. 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 unless Management intends to dispose of 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
when the groups right to receive payments is established.

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

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 is impaired. If a financial asset or a group of financial assets is impaired, the impairment losses are incurred 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.



F-15



---

##### Table of Contents

(All amounts expressed in thousands of S/ unless otherwise stated)



Evidence of impairment may include indications that the debtors or a group of debtors is
experiencing significant financial difficulty, default or delinquency in interest or principal payments, the probability that they will enter bankruptcy or other financial reorganization, and where observable data indicate that there is a measurable
decrease in the estimated future cash flows, such as changes in arrears or economic conditions that correlate with defaults.

For the
loans and receivables category, the amount of the 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.

If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be
related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtors credit rating), the reversal of the previously recognized impairment loss is recognized in the income statement.



| | 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 and available for sale is impaired.

For debt securities, if any such evidence exist 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. If, in a subsequent period, the fair value of a debt instrument classified
as available for sale increases and the increase can be objectively related to an event occurring after the impairment loss was recognized in profit or loss, the impairment loss is reversed through the income statement.

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. 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).

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-16



---

##### 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 7. 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 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 (losses) gains- 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 (see Note 2.25
for detail on Revenue from construction activities)



| | 2.12 | Inventories -
| | ---- | -------------

Inventory mainly includes land, work in progress and finished properties
which is assigned to the real- estate activity. 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.



F-17



---

##### Table of Contents

(All amounts expressed in thousands of S/ unless otherwise stated)



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, (directly attributable to the acquisition, construction and production of qualified assets), other indirect costs and general expenses related to the construction and do
not include exchange differences.

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:
these 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.

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. When a decline in the price of materials indicates that the cost of the finished products exceeds net their realizable value, the materials are written down to their replacement cost.



| | 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. A propertys carrying amount is written down immediately to its recoverable amount if the propertys carrying amount is greater than its estimated recoverable amount.

The cost and accumulated depreciation on disposals are eliminated from the respective accounts and the resulting gain or loss is recognized in
profit or loss for the period. The depreciation of this asset is calculated under the straight-line method at a rate that is considered sufficient to absorb the propertys cost over its estimated useful life and considering its significant
components with substantially different useful lives (each component is treated separately for depreciation purposes and depreciated over its individual useful life). The estimated useful life of investments properties fluctuate between 5 and 50
years.

The Group maintains only one investment property, a Shopping Mall owned by the subsidiary Viva GyM S.A. Its fair value amounted to
US$16.7 million at December 31, 2015 (US$19 million at December 31, 2014). The stores in this mall are leased to third parties under operating leases.



| | 2.14 | Property, plant and equipment -
| | ---- | -------------------------------

Property, plant and equipment are stated at historical
cost less depreciation. 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. The carrying amount of the replaced asset is derecognized. All other repairs and maintenance are charged to the income statement during the financial period in which they are incurred.

##### Table of Contents

(All amounts expressed in thousands of S/ unless otherwise stated)



Assets in the construction stage 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.

Land is not depreciated. 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:



YearsBuildings and facilities

Between 3 and 50Machinery and equipment

Between 4 and 10Vehicles

Between 2 and 10Furniture and fixtures

Between 2 and 10Other equipment

Between 2 and 10


The assets residual values and useful lives are reviewed, and adjusted as appropriate, at each
date of the statement of financial position. An assets carrying amount is written-down immediately to its recoverable amount if the assets carrying amount is greater than its estimated recoverable amount. Gains and losses on disposals
are determined by comparing the proceeds with the carrying amount and are recognized in Other income and expenses in the income statement.

Non-current assets (or disposal groups) are classified as non-current assets held for sale when its carrying amount is recovered mainly
through a sale operation and this sale is considered highly probable. These are estimated through the lowest carrying amount and the fair value amount less sale costs.



| | 2.15 | Intangible assets -
| | ---- | -------------------



| | a) | Goodwill -
| | -- | ----------

Goodwill arises on the acquisition of subsidiaries and represents the excess of
the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the identifiable net 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 of the cash-generating
units (CGU), or group of CGUs, that is expected to benefit from the synergies of the combination. Each unit or group of units to which the goodwill is allocated represents the lowest level within the entity at which the goodwill is monitored for
internal management purposes. Goodwill is monitored at the operating segment level.

Goodwill impairment reviews are undertaken annually
or more frequently if events or changes in circumstances indicate a potential impairment. The carrying value of goodwill is compared to its recoverable amount, which is the higher of its value in use and its fair value less costs of disposal. Any
impairment is recognized immediately as an expense in item other income and expenses and is not subsequently reversed.

| | b) | Trademarks -
| | -- | ------------

Separately acquired trademarks are shown at historical cost. Trademarks acquired
in a business combination are recognised at fair value at the acquisition date. Trademarks have an indefinite useful life.



| | c) | Concession rights -
| | -- | -------------------

The intangible asset related to the right to charge users for the
services related to service concessions agreements (Note 2.5 and Note 5.b) is initially recorded at the fair value of construction or improvement services. It is amortized under the straight-line method, from the date when toll collection started
using the lower of its estimated expected useful life or effective period of the concession agreement.



| | d) | 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 future cash flows expected from those relationships 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 2 and 5 years). The useful life and the impairment of these assets are individually assessed.



| | e) | Cost of development of wells -
| | -- | ------------------------------

Costs incurred to prepare the wells to extract the
hydrocarbons associated with Block I and Block V, are capitalized as intangible assets. The Company capitalizes the development stage costs associated with preparing the wells for extraction. These costs are amortized based on the useful life of the
wells (9 and 10 years for Blocks I and V, respectively), which is less than the overall period of the service contract with Perupetro.



| | f) | Internally generated software and development costs -
| | -- | -----------------------------------------------------

Costs associated with maintaining
computer software programs are recognized as an expense as incurred. 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 generate probable future economic benefits;
| | - |  | ------------------------------------------------------------------------------------------------

| | ● |  | adequate technical, financial and other resources to complete the development and to use or sell the software product are available; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------

| | ● |  | the expenditure attributable to the software product during its development can be reliably measured.
| | - |  | -----------------------------------------------------------------------------------------------------

Directly attributable costs, such as development employee costs and an appropriate portion of relevant overhead, are capitalized as part of
the software.

Other development expenditures that do not meet these recognition 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 not exceeding three years.

(All amounts expressed in thousands of S/ unless otherwise stated)



| | g) | Rights of use of land -
| | -- | -----------------------

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 their effective period may be extended if agreed by 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 tested 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. The recoverable
amount is the higher of an assets fair value less costs to sell and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units).
Non-financial assets other than goodwill that were adjusted for impairment are reviewed for possible reversal of such impairment at each reporting date.



| | 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.

Trade payables are recognized initially at fair value and subsequently measured at amortized cost using the
effective interest method, except for payables of less than one year that are stated at nominal amount which is similar to their fair values since they are short term.



| | 2.18 | Other financial liabilities -
| | ---- | -----------------------------

They comprise 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 proceeds (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.

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

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 assets in which the Group proceeds to capitalize borrowing costs are intangible assets and inventories (Note 17 and 14). The Company suspends capitalization of a qualifying asset during periods
in which active 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. All other borrowing costs are recognized in profit or loss in the period in which they are incurred.

| | 2.20 | Current and deferred income tax -
| | ---- | ---------------------------------

The tax expense for the period comprises
current and deferred tax. Tax is recognized in the income statement, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In this case, the tax is also recognized in the statement of
comprehensive income or directly in equity, respectively.

The current income tax charge 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 income tax is recognized, using the liability method, 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 the deferred income tax liability 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.

The
deferred income tax arising from the temporary differences in investments in subsidiaries, associates and interest in joint-controlled businesses is not recognized as the tax legislation in Chile, Colombia, Panama, Brazil, Bolivia, Guyana, Dominican
Republic and Peru does not consider the income from dividends as a taxable item and the Group expects to recover the investment through the dividends rather than their sale.



| | 2.21 | Employee benefits -
| | ---- | -------------------



| | a) | Profit sharing -
| | -- | ----------------

The 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% of the taxable income determined separately by each of the Groups Peruvian entities, according to the income
tax law currently in force. The branch based in the Dominican Republic has a similar profit sharing scheme, which rate is 10% of the taxable income. For the particular case of Chile, workers profit sharing is a component of remuneration
(equivalent to 4.75% of the minimum annual salarie) rather than a percentage based on profit. In Brazil, Colombia and Guyana no such benefits are paid to workers. In Bolivia workers profit sharing is equivalent to a one-month salary and their
total amount cannot exceed 25% of profits.

| | b) | Bonuses -
| | -- | ---------

The Peruvian entities of the Group recognize an expense and the related liability
for statutory bonuses based on applicable laws and regulations effective in Peru. Statutory bonuses comprise two additional one-month salaries paid every year in July and December, respectively. According to Chilean legislation, employees receive a
fixed amount in September and December. In Brazil, Colombia and Dominican Republic these benefits are not provided to employees. In Brazil, Colombia and Dominican Republic no such benefits are paid to workers. In Bolivia a statutory bonus is paid to
workers that equals an additional one-month salary and settled net every December, without deductions per year of service as well as an additional one-month salary, which is dependent on the country growth to be equal or above 4.5%. In Guyana,
statutory bonuses are paid once in December (equivalent to a one-month salary) and the second one is prorated on a monthly basis along the year (also equivalent to a one-month salary).



| | c) | Severance indemnities -
| | -- | -----------------------

The employees severance payments for time of service of the
Groups Peruvian staff comprise their indemnification rights, calculated in accordance with the regulations in force, which have to be credited to the bank accounts designated by workers in May and November each year. The compensation for time
of service amounts to an additional one-months salary effective at the date of bank deposits. In Colombia, this is 1.11 times the monthly remuneration and in Chile i is 3.8% of the monthly salary. There is no such benefit in Guyana. The Group
does not have any additional payment obligation once the annual deposits are made of the amounts workers are entitled to.



| | d) | Vacation leave -
| | -- | ----------------

Annual vacation leave is recognized on an accrual and cumulative 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 and Brazilian employees and fifteen days for Chilean, Dominican and Colombian
employees per year. In Bolivia vacation leave depends on seniority of a worker and range 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 defined benefit obligation is calculated annually by independent actuaries using the projected unit credit method. 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.

Remeasurements 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.

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

Group entities recognize 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 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, according to IFRIC 1 Changes in Existing Decommissioning, Restoration and Similar
Liabilities; 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, according to the guidelines of IAS 36, Impairment of
assets (Note 2.16).



| | c) | Provision for periodic maintenance -
| | -- | ------------------------------------

The service concession arrangement of Norvial has
maintenance obligations that it must fulfill during the operation phase to maintain the infrastructure to a specific level of service at all times and to restore the infrastructure to a specified level condition before it is handed back to the
grantor. The Group recognizes and measures such obligations, except for an upgrade element, in accordance with IAS 37, Provisions, contingent assets and liabilities. The Company apply a criteria of maintenance provision based on the use of the
infrastructure, so the level of use of the road is the fact that determines the amount of the obligation over the time.



| | 2.23 | Put option arrangement -
| | ---- | ------------------------

This liability is measured by the expected cash outflows that
would be required if the option is exercised discounted at the date of the financial statements. Subsequently, the financial liability is updated for changes in the expected cash outflows that would be required and the financial component for the
passage of time. The effects of this update are recognized in profit or loss.

| | 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. Revenue is stated net of sales rebates, discounts and value added taxes and after eliminating sales between Group companies.

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 of the contract based on the completion of a physical proportion of the contract work considering total costs and revenues estimated at the end of the project, in accordance with IAS 11, Construction Contracts.
Under the physical proportion method revenues are determined based on the proportion of actual physical completion compared to the total contract physical construction commitment.

When it is probable that the total costs of 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 are 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 in-process 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 payables.

Accounts receivable derived from work
services are shown net of the advances received from customers to the extent the related contracts include settlement provisions.

A
variation is an instruction by the customer for a change in the scope of the work to be performed under the contract. A variation 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.

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

For sales
of services, revenue is recognized in the accounting period in which the services are rendered.



| | iii) | Sales of 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 as a percentage of the total services to be performed during the period of service.



| | v) | Interest income -
| | -- | -----------------

Revenue from interest is recognized on a time-proportion basis, using the
effective interest method.



| | vi) | Revenue for concession services -
| | --- | ---------------------------------

Revenue for 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 -
| | ---- | -----------------------------

Construction contract costs are recognized as an expense
in the period in which they are incurred.

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.

(All amounts expressed in thousands of S/ unless otherwise stated)



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.

Changes in contract
relating to the work to be performed, lawsuits and payment of incentives are included in the revenue from the contract to the extent that they have been agreed with the client and can be measured reliably.



| | 2.27 | 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 (net of any incentives received from the lessor) are charged to the profit or loss of the period on a straight-line basis over the period of the
lease. The Groups major operating leases are computer and printing equipment leases and the temporary rent of the facilities in the district of Miraflores.

The Group leases certain property, plant and equipment. Leases of property, plant and equipment where the Group has substantially assumed all
the risks and rewards of ownership are classified as finance leases. Finance leases are capitalized at the leases commencement at the lower of the fair value of the leased property and the present value of the minimum lease payments.

Each lease payment is allocated between the liability and finance charges in order to obtain a constant rate on the balance pending payment.
The corresponding rental obligations, net of finance charges, are included in other long-term payables. The interest element of the finance cost is charged to the income statement 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 are depreciated over the shorter of the useful life of the asset and the lease term.



| | 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 better understanding of the Groups financial performance. These material items are income or expenses shown separately due to the significance of their nature or amount.



| | 2.30 | New standards, amendments and interpretations -
| | ---- | -----------------------------------------------



| | a) | New standards, amendments and interpretations adopted by the Group in 2015
| | -- | --------------------------------------------------------------------------

The Company has
used for the first time the following IFRS and amendments to IFRS in the preparation of its financial statements for 2015:



| | - | IFRS annual improvements for 2010-2012 and 2011-2013 cycles.
| | - | ------------------------------------------------------------



| | - | Defined Benefit Plans: Employee contributions  amendment to IAS 19, Employee Benefits.
| | - | -----------------------------------------------------------------------------------------

Adoption of annual improvement for the 2010-2012 and 2011-2013 cycles have only required additional minor disclosures. This improvements have
not had a significant impact on the current and prior years and they are not likely to affect future periods.

| | b) | New standards and amendments and interpretations effective for the financial statements for annual periods beginning on or after January 1, 2016 not yet adopted -
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | - | IFRS 9, Financial instruments, addresses the classification, measurement and recognition of financial assets and financial liabilities. The complete version of IFRS 9 was issued in July 2015. It replaces the
guidance in IAS 39 that relates to the classification and measurement of financial instruments.
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

IFRS 9 retains but
simplifies the mixed measurement model and establishes three primary measurement categories for financial assets: amortized cost, fair value through Other Comprehensive Income and fair value through Profit and Loss. The basis of classification
depends on the entitys business model and the contractual cash flow characteristics of the financial asset. Investments in equity instruments are required to be measured at fair value through profit or loss with the irrevocable option at
inception to present changes in fair value in Other Comprehensive Income not recycling. There is now a new expected credit losses model that replaces the incurred loss impairment model used in IAS 39. For financial liabilities there were no changes
to classification and measurement except for the recognition of changes in own credit risk in other comprehensive income, for liabilities designated at fair value through profit or loss. IFRS 9 relaxes the requirements for hedge effectiveness by
replacing the bright line hedge effectiveness tests. It requires an economic relationship between the hedged item and hedging instrument and for the hedged ratio to be the same as the one management actually use for risk management
purposes. Contemporaneous documentation is still required but is different to that currently prepared under IAS 39.

The standard is
effective for accounting periods beginning on or after January 1, 2018. Early adoption is permitted. As part of the evaluation of the impact of to this standard, the Group does not expect the changes introduced by the IFRS 9 may have a material
impact on the criteria and measurement of financial assets and liabilities that are currently applied by the Group.



| | - | IFRS 15, Revenue from contracts with customers
| | - | ------------------------------------------------

The standard replaces IAS 18
Revenue and IAS 11 Construction contracts and related interpretations. The new standard is based on the principle that revenue is recognized when control of a good or service transfers to a customer  so the notion of
control replaces the existing notion of risks and rewards. The newly issued standard introduces a five-step process for revenue recognition, as follows: (i) identifying the contract with a customer, (ii) identifying separate performance
obligation, (iii) determining the transaction price, (iv) allocate the transaction price to the separate performance obligations and (v) Recognize Revenue When (or as) Performance Obligations Are Satisfied. The application of IFRS 15
may have an effect on the timing and amount of revenue recognition as well as on the business processes, systems and internal controls that may require changes for adequately meeting the new requirements. Entities have the option of a full
retrospective application and a retrospective application with additional disclosures. The standard is effective for annual periods beginning on or after January 1, 2018 and earlier application is permitted. The Group is assessing the impact of
IFRS 15 application of which is not expected to have a significant impact on revenue recognition. The Company is considering transition options established for IFRS 15 and the effect on the current contracts signed with the other subsidiaries.

| | - | Amendments to IFRS 11, Joint arrangements.
| | - | --------------------------------------------

The amendments to IFRS 11 clarify the
accounting for the acquisition of an interest in a joint operation where the activities of the operation constitute a business. They require an investor to apply the principles of business combination accounting (NIIF 3) when it acquires an interest
in a joint operation that constitutes a business. This includes: (i) measuring identifiable assets and liabilities at fair value, (ii) expensing acquisition-related costs, (iii) recognizing deferred tax, and (iv) recognizing the
residual as goodwill, and testing this for impairment annually. Existing interests in the joint operation are not remeasured on acquisition of an additional interest, provided joint control is maintained. The amendments also apply when a joint
operation is formed and an existing business is contributed.



| | - | IAS 1 Presentation of financial statements disclosure initiative.
| | - | -------------------------------------------------------------------

The amendments
to IAS 1 Presentation of Financial Statements are made in the context of the IASBs Disclosure Initiative, which explores how financial statement disclosures can be improved. The amendments provide clarifications on a number of issues,
including:



| | (i) | Materiality: an entity should not aggregate or disaggregate information in a manner that obscures useful information. Where items are material, sufficient information must be provided to explain the impact on the
financial position or performance.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (ii) | Disaggregation and subtotals: line items specified in IAS 1 may need to be disaggregated where this is relevant to an understanding of the entitys financial position or performance. There is also new
guidance on the use of subtotals.
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (iii) | OCI arising from investments accounted for under the equity method: The amendments require that the share of other comprehensive income arising from investments accounted for under the equity method is grouped
based on whether the items will or will not subsequently be reclassified to profit or loss. Each group should then be presented as a single line item in the statement of other comprehensive income.
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (iv) | Notes: confirmation that the notes do not need to be presented in a particular order.
| | ---- | -------------------------------------------------------------------------------------



| | - | IFRS 16 Leases
| | - | ----------------

On January 13, 2016, IFRS 16, Leases (IFRS 16)
was issued replacing the current guidance (IAS 17, Leases and IFRIC 4, Determining whether an arrangement contains a lease and other related standards). IFRS 16 introduces a new definition of a lease and a new accounting
model that will have a material impact on lessees. As a result of the new accounting treatment, an entity is required to recognize in the statement of financial position, at the inception of the lease, an asset for the right of use of the leased
asset and a liability for the obligations to make future contractual payments. At initial recognition, the asset and liability will be measured at the present value of the minimum lease payment under contract. As a result of this change, a large
number of leases classified as operating leases under the current standards will be shown on the face of the statement of financial position from the inception of the lease.

This new accounting model is applicable to all contracts qualifying as leases, excepted for those contracts with an effective period of less
than 12 months (considering in that determination the likelihood of contract extension) and lease contracts of assets that are considered immaterial.

The standard applies to annual periods beginning on or after January 1, 2019, with earlier application permitted if IFRS 15, Revenue from
Contracts with Customers, is also applied.

The Group is currently evaluating the impact these standards may have on the preparation of
its financial statements. There are no other IFRSs or IFRIC interpretations that are not yet effective that would be expected to have a material impact on the Groups financial statements.



| | 2.31 | Reclassifications -
| | ---- | -------------------

The Group has changed its accounting policy for the presentation
of interest payments in the Statement of Cash Flows under Operating activities. Until 2014, interest payments were presented under Financing activities; the change in 2015 resulted from Managements assessment that interest payable on obtaining
notes and bank borrowings are mainly related and have been used to meet working capital needs for the concession projects signed with the Peruvian Government and other major projects in the Construction segment; accordingly, the change is intended
to provide the financial statements users with more relevant and consistent information by presenting interest within cash flows from operating activities considering their nature and main purpose. For comparison purposes the change in accounting
policy has been applied to 2013 and 2014 figures.

Additionally, due the review of the provisional allocation of the purchase price in
business combination transactions some assets and liabilities of 2014 figures were adjusted (note 32-a).



|3 | 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.



| | 3.1 | 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, 2015 and 2014, this exposure is mainly concentrated in fluctuations of the U.S. dollar, Chilean and Colombian Pesos. The foreign exchange
risk of the investments in Brazil, Bolivia, Panama and Dominican Republic are not significant due their level of operations.

As of
December 31, 2015, the consolidated statement of financial position includes assets and liabilities in foreign currency (mainly in U.S.dollar) equivalent to S/1,659 million and S/2,404 million, respectively (S/1,316 million and S/1,677 million,
respectively, as of December 31, 2014) equivalent to US$486.7 million and US$704.5 million respectively (US$455.5 million and US$580 million, respectively as of December, 2014).

During 2015, the Peruvian Sol the Chilean and Colombian Pesos have been exposed against the U.S. dollar. The Groups exchange gains and
losses for 2015 amounted to S/427.2 million and S/510.1 million, respectively (S/357.3 million and S/401.6 million, respectively in 2014, and S/431 million and S/501 million, respectively in 2013).

(All amounts expressed in thousands of S/ unless otherwise stated)



If, at December 31, 2015, the Peruvian Sol and the Chilean and Colombian Pesos had
strengthened/weakened by 2% against the U.S. dollar, with all variables held constant, the pre-tax profit for the year would have increased/decreased by S/1.7 million (S/0.9 million in 2014 and S/1.4 million in 2013).

As of December 31, 2015, the consolidated statement of changes in equity comprises a foreign currency translation adjustment originated
by its subsidiaries. Their financial position include assets and liabilities in functional currency equivalent to Ch$85,238 million and Ch$80,378 million, respectively (Ch$109,187 million and Ch$62,163 million, respectively as of December, 2014),
Col$265,370 million and Col$309,446 million respectively (Col$189,649 million and Col$149,150 million, respectively as of December, 2014), b$61.4 million and b$92.6 million respectively (b$0.1 million and b$0.2 million, respectively as of December,
2014). At the end of 2015, the Group does not maintain records in reales (R$20.1 million and R$7.1 million respectively, as of December, 2014).

The Group ́s foreign exchange translation adjustment for 2015 amounted to S/44.6 million (S/20.5 million in 2014 and S/1.1 million in
2013).



| | 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 in fixed rate instruments; 72.7% of total debt in 2015 (97% in 2014) was contracted at fixed rates and 27.3% at variable rates (3% in 2014), which is comprised of a 23.6% rate plus VAC (adjusted for inflation) and the remaining 3.7% at
variable rate.

The debt subject to rate + VAC is the interest rate on a bond issued in Peruvian soles to finance the Metro Line 1 Project
(GyM Ferrovías). 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 2015 and 2014 the Groups 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. The increase or decrease of 5% in interest rate would not have a material effect on the Groups results. There was no
material ineffectiveness on cash flow hedges occurred in fiscal years 2015 and 2014.



| | 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.

For accounts receivable, Management of each of the Groups companies evaluates the credit quality of the
client taking into consideration its financial position, past experience and other factors. Individual risk limits are set based on internal or external ratings in accordance with limits set by the board. The utilization of credit limits is
regularly monitored.

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.



| | 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. In this sense, the Group has no significant liquidity risks given the fact that
historically its cash flows have enabled it to maintain sufficient cash to meet its obligations.

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 committed borrowing facilities (Note 18), 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 following table 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.

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.

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.

As of December 31, 2015, the gearing ratio is presented below indicating
the Companys strategy to keep it in a range from 0.10 to 0.70.

As of December 31, the gearing ratio was as follows:

| | 3.3 | 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 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. The fair value of financial liabilities, disclosed in Note 18-c) and Note 19, 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).



|4 | 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.



| | 4.1 | 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 have suffered any impairment, in accordance with the policy described in Note 2.15-a). For this purpose, goodwill is attributed 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 sale. 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 the preparation of 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 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 the 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 necessary.

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 are revenue, gross margin, growth rate and discount rate which are included in Note 17.

In 2015, if the gross margin and discount rate had been 10% less than Managements estimates, the Group
would have recorded a provision for impairment of goodwill resulting from CGU Engineering and Construction. In 2014 if gross margin had been 10% less than Managements estimates, the Group would have recorded a provision for impairment of
goodwill resulting from the CGU of IT goods and services.

As a result of our sensitivity analysis, provision for impairment of goodwill
and/or trademarks would have not been necessary to be recorded under any other scenarios.



| | b) | Income taxes -
| | -- | --------------

Determination of the tax obligations and expenses requires interpretations of
the applicable tax laws and regulations. The Company seeks legal tax counsels advice 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 by taking the temporary differences of the tax basis of assets and liabilities and the financial statement basis using the tax rates in effect for each of the years in which the difference is expected to reverse. Any
change in tax rates will affect the deferred tax assets and liabilities. This change will be recognized in income in the period 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 positive and negative 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 maximum exposure of the Group related to tax contingencies amounts to S/37.9 million.

| | c) | Percentage of completion revenue recognition -
| | -- | ----------------------------------------------

Revenue from construction contracts is
recognized under the percentage-of-completion method which requires the final margin from construction contracts to be estimated. Projections of these margins are performed by Management based on work execution budgets and adjusted periodically
based on updated information reflecting the actual performance of work. In this regard, Management considers that the estimates made at the year-end closing are reasonable. When unapproved change orders occur, revenue is recognized equal to costs
incurred (no profit component recognized) until the additional work is approved.

Contract revenue is recognized as revenue in the income
statement in the accounting periods in which the work is performed. Contract costs are recognized as cost of sales in the income statement in the accounting period in which the work to which they relate is performed. However, any expected and
probable excess of total contract costs over total contract revenue for the contract is expensed immediately. Furthermore, any changes in contract estimates are recognized as a change in accounting estimates and recognized in the period the change
is made and in future periods as applicable. In certain construction contracts, the terms of these agreements allow for an amount to be withheld by the customers until construction has been completed. Under these contracts the full amount may not be
recognized until the next operating cycle. As of December 31, 2015, 2014 and 2013, a sensitivity analysis was performed considering a 10% increase/decrease in the Groups gross margins, as follows:

| | d) | Provision for well closure costs -
| | -- | ----------------------------------

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 discount
pre-tax rate used for the present value calculation was 2.09% based on the 7 year bond rate as of December, 2015 (2.17% based on the 10 year bond rate as of December, 2014).

At December 31, 2015 the present value of the estimated provision for closure activities for 78 wells amounted to S/7.3 million (S/7.2
million as of December 31, 2014 for closure activities for 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 obligations originally estimated (Note 17).

If, at December 31, 2015 and 2014, the estimated rate would have
increased or decreased by 10%, with all variables held constant, the impact on pre-tax profit would have not been significant.

During
2015, the Company recorded a provision amounting to S/0.1 million to reflect the estimated obligation to close productive wells included in the service agreements for Blocks I and V (S/2.7 million in 2014). The provision for blocks III and IV at
December 31, 2015 is nil because at year - end 2015 there is no available information regarding well numbers requiring to be closed.

|9 | OTHER FINANCIAL ASSETS
|- | ----------------------

This account comprises the investment held by the Company,
directly and indirectly, in Transportadora de Gas del Perú S.A. (TGP), a Peruvian entity engaged in providing gas transportation services.

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
(S/93.1 million at December 31, 2014). The information used in the calculation is 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 is 7.5% corresponding to estimated TGPs WACC (8.1% at December 31, 2014).
| | - | -------------------------------------------------------------------------------------------------

| | - | The interest of the Company in TGP is 1.64% at December 31, 2015 and 2014.
| | - | --------------------------------------------------------------------------

The
fluctuation in the fair value of this investment in 2015 amounts 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), plus the adjustment for changes in income tax rate (see note
29-b) amounting to S/1.1 million, which has been recognized in the statement of other comprehensive income.

The most significant
assumptions are the discount rate and cash flows affected by the U.S. Wholesale Price Index; the Group has performed a sensitivity analysis on this assumptions: if the discount rate was adjusted down by 5% the fair value would be 7.4% lower and if
the discount rate was 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.

Collection rights as of December 31, 2015 mainly comprises GyM Ferrovías S.A.,GMD
S.A., GMI S.A. and Survial for S/65 million, S/37 million, S/22 million and S/16 million respectively (GyM Ferrovías S.A., CAM Holding S.A, GMD S.A., GMI S.A., Concar S.A., Viva GyM S.A. and Canchaque for S/116 million, S/51 million, S/31
million, S/37 million, S/35 million, S/6 million and S/2 million respectively in 2014).

The collection rights that arise from GyM
Ferrovías S.A., a concession signed with the Peruvian Government comprising Line 1 of the Lima Metro (train line), by which this entity has to acquire, on the Governments behalf, certain infrastructure needed for the implementation of
the transport system that will be operated by the GyM Ferrovías S.A once completed (Note 5-b). This account will be amortized through the cash flows determined at the inception of the concession under the price per kilometer
traveled method (PKT).

Collection rights from Survial S.A. consists of the PAMO provision, specifically the last instalment for the
current year (October  December) set forth under the Concession Agreement; which is billed and actually cashed the month following the end of the quarter. At the reporting date, the October  December installment has already been
invoiced.

For this purpose, the subsidiary has applied certain criteria to determine the amount of the interest to be accrued on the
outstanding balances and the beginning of the collection of the amounts pending. These balances bear interest at a 7.7% rate and their collection began in 2014 jointly with the beginning of operation.

(All amounts are expressed in thousands of S/ unless otherwise stated)



Rights receivable correspond to the unbilled rights for services rendered by the Engineering
and Construction Segment. Each month, under the percentage of completion method, the Company estimates the work completed to date. Based on its monthly estimates, the Company recognizes the corresponding revenue. Until such revenue is billed, it is
recorded in the account rights receivable.

At December 31, 2015 and 2014, unbilled work in progress are presented net of advances
received from clients for S/42.5 million and S/334 million, respectively the terms of which vary based on each contract. These advances substantially correspond to those received by subsidiary GyM S.A.

At December 31, 2015, advances amounting to S/33 million, correspond to a scheme by mean of which certain customers agree to grant
revolving monthly advances which are settled with the amount billed the month following the reception of the advance (S/305 million at December 31, 2014). Other advances received from customers are recognized netting the corresponding
receivables and are offset following the pattern of actual services provided. In these cases, if the contract is terminated, the amount received in advance is offset against any receivable balance determined by the work in progress at termination
date.

Deferred costs of work in progress include all those expenditures incurred by the Group that relate to future activities to be
performed under current construction contracts. At December 31, 2015, the balance mainly comprises costs incurred in the following projects: Kellar, Costa Norte, Proyecto Nuis, Menegua, Poliductos, Red de Gas de Contugas, Servicio Carretera
Quinua San Francisco Tranch 2 and Incolur for S/38.4 million, S/34.1 million, S/28.8 million, S/27.3 million, S/21.8 million, S/17.3 million, S/7.6 million and S/1.8 million, respectively (concentrating Plant Cerro Verde, Las Bambas, Machu Picchu,
Servicios Cerro del Águila and Chile Spa for S/53.8 million, S/32.9 million, S/31.4 million, S/22.3 million and S/12.7 million, respectively at December 31, 2014).

Other smaller projects for which certain cost amounting to S/6.8 million have been deferred are: CH Santa Teresa 90MW, Cerro Verde 2
Concentrating Plant Phase 1 and improvement and expansion of INEN (S/52 million for Red Gas Contugas, Preliminary work Aurora Gold, Pad I FASE III Cerro Verde at December 31, 2014).

The non-current portion mainly comprises the expenditures incurred by Concesionaria Vía Expresa Sur S.A. for S/19.0 million (S/10.5
million at December 31,2014) that related to future activities to be performed under the construction contract (implementation of the 4.6 km extension of Vía Expresa Sur connecting the district of San Juan de Miraflores).
This Project is expected to be completed in August 2018.

Additionally the non-current portion comprises the expenditures incurred by the
subsidiary GMP S.A. for S/40.7 million for work in progress related to Transportadora de Gas Natural Comprimido Andino Concession (S/25.4 million at December 31, 2014). This Concession is in a pre-operative stage.

Other receivables do not have past due nor impaired. Other non-current accounts receivable have maturities
between 2 and 5 years. Companys Management estimates that the fiscal credit will be applied against the credit balance of the corresponding tax over the medium term.

The fair value of the short-term receivables approximates to the carrying amount due to its short-term maturity. Non-current portion is not
significant for the financial statements for any period shown.

Maximum exposure to credit risk at the reporting date is the carrying
amount of each class of other receivables mentioned. The Group does not require guarantees.

The most significant associates are described as follows:



| | i) | Gasoducto Sur Peruano S.A. -
| | -- | ----------------------------

In November 2015 the Group acquired a 20% interest in Gasoducto
Sur Peruano S.A. (GSP), an entity which, on July 22, 2014, signed a concession agreement with the Peruvian Government (Grantor) to build, operate and maintain the natural gas pipeline transportation system to satisfy the demand of the Peruvian
southern region cities, such as: Quillabamba, Cusco, Puno, Arequipa, Moquegua and Tacna. Under the provisions of the concession agreement, the Grantor guarantee GSP returns on the investment made. The term of the concession is 34 years and
GSPs current activities substantially involve those needed for the constructions of the pipeline transport system.

(All amounts are expressed in thousands of S/ unless otherwise stated)



The estimated investment in constructing this infrastructure approximately amounts to US$
5,900 million. In carrying out major activities for the construction and implementation of the pipeline transportation system, GSP has signed an engineering, procurement and construction contract (EPC) with Consorcio Constructor Ductos del Sur
(CCDS). In conjunction with the acquisition of 20% interest in GSP, the Group obtains 29% interest in CCDS through its subsidiary GyM S.A.

This acquisition is part of the Groups strategy to provide services to the energy sector; also, this acquisition has enabled the Group
to increase its backlog volume relating to the engineering and construction segment.

GSP was originally incorporated by two entities,
Inversiones en Infraestructura de Transporte de Ductos S.A.C. (IITD) and Enagás. The Groups acquisition of GSP interest was made as a result of IITDs assignment to the Group of its preferred subscription right to increase capital
in GSP. According to the contract signed in November 2015, the economic impact for the Group from the acquisition of GSP is summarized as follows:



| | (a) | With respect to GSP acquisition, the Group has made capital contributions of US$131 million (equivalent to S/438 million) which includes premium on the par values of the subscribed shares. It is expected that additional
contributions of the Group to GSPs share capital during the Projects construction phase amount to US$84 million, which would represent a total investment of the Group in GSP of US$215 million.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | The Group has the obligation to assume 20% of the performance bond required under the concession agreement and 20% of the collateral of a bridge loan obtained by GSP for US$600 million, and,
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | With respect to the assignment of the preferred subscription right by IITD, the Group has the obligation to pay US$2.9 million (equivalent to S/ 9.7) and assumes an obligation with IITD to pay at the end of the first
year of commercial operation of the concession, which is expected to begin on year 2018, or on the date the Group decides to sell part or the entirety of the acquired investment, 20% of the difference arising from the fair value of the acquired
shares at that date and the expected fair value that those shares would have at the end of the first year of commercial operation, according to a valuation performed in 2014 by an appraiser.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

At the acquisition date, the Group allocated the purchase price to the provisional determination of the fair values of the acquired assets and
liabilities assumed.



| | ii) | Asociación en Participación Panorama Plaza de Negocios -
| | --- | --------------------------------------------------------

It is through this
associate that the Panorama real estate property Project is being developed, comprising the construction and sales of offices and commercial spaces in the district of Santiago de Surco. This Project was initially developed by a third party but in
2014 the Group joined the Project through its subsidiary Viva GyM S.A. and with a capital contribution of S/37.8 million; as a result the Group obtained 35% interest in the Project as well as significant influence in the operating decision-making.

On December 17, 2015 given the interest of both parties to directly and actively take part in the implementation and management of
the Project, the decision was made to change its corporate structure, which resulted in the extinction of the associate and the formation of a joint operation that enabled the parties to have control over the joint operation without affecting their
share in profits. From that date on, the Group has ceased to apply the equity method of accounting to recognize this investment and is recognizing it as a joint operation.

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

24,957,300 m2 located in Lurin, which will be used for real estate developments. Based on recent appraisals of the property, Management believes that the commercial value of this property is
higher that its carrying amount.



| | iv) | Concesionaria Chavimochic S.A.C. -
| | --- | ----------------------------------

An entity that was awarded with the implementation of the
Chavimochic irrigation Project, including: a) design and construction of the work required for the third-phase of the Chavimochic irrigation project in the province of La Libertad; b) operation and maintenance of works; and c) water supply to the

##### Table of Contents

(All amounts are expressed in thousands of S/ unless otherwise stated)



In 2015 and 2014, additions to cost correspond to the acquisition of fixed assets under
finance leases and by direct acquisition.

The balance of work in progress at December 31, 2015, relates mainly to investments made
by the subsidiary GMP S.A. for S/3 million (S/47.4 million at December 31, 2014) for the activities of oil drilling in order to increase exploitation of oil and gas (4 wells in 2015 and 25 wells in 2014). Additionally, the balance includes the
construction work of Larcomar Hotel Project for S/11.0 million (S/9.3 in 2014). At December 31, 2014 the balance included the construction of the offices in the new administrative headquarters of the Company in Petit Thouars Avenue, amounting
to S/28.9 million and the subsidiary GyM S.A. maintained a balance of S/12.4 million relating to the construction of a corrective-preventive maintenance at the Constancia mine.

In 2015 the sale of fixed assets amounted to S/55.8 million (S/124.2 million and S/47.3 million in 2014 and 2013, respectively), resulting in
a profit of S/17.4 million (a profit of S/4.9 million and S/0.7 million in 2014 and 2013, respectively), which is shown in the income statement under other income and expenses (Note 28).

Depreciation of fixed assets and investment properties for the year is broken down in the statement of income as follows:

| | a) | Goodwill -
| | -- | ----------

Management reviews the results of its businesses based on the type of economic
activity carried out.

Goodwill from cash-generating units is allocated to the following segments:



|                                               |  |                 |         |  |      |  |         |

|                                               |  |                 | 180,149 |  |      |  | 184,808 | 
|                                               |  |                 |         |  |      |  |         | 

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 (CGU) is determined based on the higher of its value in use and fair value less cost to sale. 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 no provisions for impairment were required.

The main criteria used by the Group to determine the value in use
are as follows:

These assumptions have been used for the analysis of each CGU included in the operating segments for a
period of 5 years.

Management determines the budgeted gross margins based on past results and market development expectations. Average
growth rates are consistent with those prevailing in the industry. Discount rates used are pre-tax and reflect the specific risk related to the assessed CGUs.



| | b) | Trademarks -
| | -- | ------------

The Group acquired trademarks from the business combination processes of Vial y
Vives S.A.C. (S/75.4 million) in October 2012 and of Morelco (S/33.3 million) in December 2014. Management has determined that both brands have indefinite lives; consequently, annual impairment tests are performed on these intangibles, as described
in paragraph a) above. As a result of these tests, no provision for impairment was considered necessary to be recorded at December 31, 2015 and 2014.

| | c) | Concessions -
| | -- | -------------

This intangible asset mainly includes the value attributable to the concession
for the Ancón-Huacho-Pativilca road section of the Panamericana Norte highway. During 2015, the Company has capitalized financing costs for these concessions amounting to S/7.7 million at interest rates between 6.75% and 8.375% (S/0.7 million
in 2014 at interest rate of 6.32%).

Intangibles arising from this concession as of December 31, 2015 mainly comprise i) the EPC
contract for S/317.5 million (S/184.1 million as of December 31, 2014) by the construction of the second section of Ancón-Huacho-Pativilca highway, with an addition of S/133.2 million net of amortization, made effective in
2015 (an investment of S/82.7 in 2014) and, ii) improving road by S/19.6 million as of December 31, 2015 (S/21.5 million as of December 31, 2014). Under those contracts, the Concessionaire has to construct, improve and rehabilitate the
road infrastructure over the effective period of the concession.

During the course of 2015 investments were made in concession Vía
Expresa Sur for S/6.2 million (S/15.8 million in 2014) involving the extension of the Vía Expresa Sur to connect the district of San Juan de Miraflores, those amounts comprises an unsecured portion (53%) for the concessionaire
(bifurcated model).



| | d) | Costs of development of wells -
| | -- | -------------------------------

Through one of its subsidiaries, the Group operates and
extracts oil from two 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 - Perupetro) located in the Talara, Piura basin.

Based on its winning technical - economic proposal,
GMP was to begin drilling activities in 230 development wells in Block III and in 330 development wells in Block IV for 10 years. The expected total investment in both blocks totals US$560 million. Operations started in April 2015 in both blocks
with a production of 1,700 bpd while the drilling obligation comes into effect one year after the beginning of operations.

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 to be able to render hydrocarbons exploitation services which will be capitalized as in intangible at a
carrying amount of S/110.2 million, S/0.1 million, S/0.2 million and S/7.9 million at December 31, 2015, respectively (S/125.1 million and S/6.2 million At December 31, 2014 in blocks I and V, respectively). All blocks are amortized on the
basis of the useful lives of the wells (estimated to be 5 years), which is less than the total effective period of the service agreement with Perupetro. Regarding Blocks III and IV those costs have not been amortized in 2015 because the investment
was actually performed on December 31, 2015.

Legal claims

Legal claims maintained at December 31, 2015 mainly comprise provisions for labor liabilities and tax claims recorded by subsidiaries GyM
S.A., GMP S.A. and CAM Chile for S/5 million, S/6.1 million and S/3.0 million, respectively (S/5 million, S/6.8 million and S/1.3 million at December 31, 2014, respectively).

Provisions related to GyM S.A. comprise claims from the tax authority which have been accounted for based on management estimates of the
amounts the Company would most likely be required to pay for these cases. Regarding tax claims, due to the fact those amounts will depend on the tax authority, the Group does not have an estimated timing of when these outflows will take place.

With respect to GMP, legal claims consists of court actions brought against the Company by the Peruvian energy regulator (OSINERGMIN)
resulting from the storage of hydrocarbons and the applicable environmental laws and regulations.

Contingent liabilities MORELCO

At the end of December 2014, the Groups subsidiary, GyM S.A. acquired control of Morelco S.A.S. by purchasing 70.00% of its equity
shares. As a result of the acquisition, tax contingencies were recorded for S/17.2 million, labor contingencies for S/5.7 million and legal contingencies for S/0.5 million. During 2015, a total of S/5.2 million tax contingencies were cancelled and
S/1.2 million was reversed for labor contingencies that expired during the year.

Contingent liabilities CAM

In 2015 the Company recognized a reversal of approximately S/7.8 million (S/9.4 million in 2014 and S/13.6 million in 2013) in provisions that
were accounted for in the acquisition of CAM Chile and affiliates in 2011 that related to labor and tax contingencies which related liabilities expired during the year.

Provision for well closure

Comprise the obligation of GMP with Perupetro relating to the abandonment of the wells of Block I and V. Under a preliminary estimate, 70
wells of Block I and 15 wells of Block V should be closed. The closure process for both wells began in 2013 and it is expected to be completed in 2021 and 2023, respectively. In 2015 no well has been closed (4 wells in Block I and 1 well in
Block V for 2014 and 1 well for each block were closed in 2013).

The provisional payment on absorbed profits (hereinafter PPUA) comprises the recovery of the first-category
income tax (Chilean corporate tax) on own profits and profits obtained from other entities in which the entity has an interest (third-party attributable profits) and which have been partially or fully absorbed against tax losses. In 2014, VyV-DSD
S.A. have recognized PPUA on carried forward tax losses of Ingeniería y Construcción Vial y Vives S.A as a result of the re-organization of the Chilean entities for S/5.9 million .

VyV  DSD S.A. has a tax goodwill credit balance (higher acquisition valued paid over the acquirees own tax capital) which arose
from the reorganization of entities that took place in 2014, which, under Chilean applicable tax laws and regulations is not considered a loss in the period in which it is generated and was proportionally allocated to the non-monetary assets
received from the acquiree up to the market price of those assets, increasing the tax cost of those assets; any reversals will affect profit or loss. The unallocated portion will be considered as deferred expenses and will be deducted as a tax
expenses over a period of 10 years. The allocation performed was as follows: S/8,560 investments, S/2,114 fixed assets and S/9,768 deferred expenses (non-attributable portion).

purchase price allocation process and based on external lawyers reports, the Company accounted for a provision amounting to S/102.7 million for contingent liabilities mainly related to labor and tax issues considered as possible and probable as
stated by IAS 37, which have expiration dates according to legal requirements between 2012 and 2016. Most of the amount shown in this account corresponds to the reversal of this provision. The amount recognized as other income and expenses
mainly corresponds to the reversal of such original registry amounted to S/7.8 million in 2015 (S/9 million in 2014 and S/13.6 million in 2013, respectively); and primarily reflects the liabilities that expired under the laws of each country during
year 2012, 2013 and 2014.

(TGP) classified as available for sale financial assets for S/7.2 million (S/9.4 million and S/1.1 million in 2014 and 2013, respectively) and recognized a commission fee for S/7.5 million) (Note 9).

| | 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.



| | c) | Amendments to Income Tax Law in Chile -
| | -- | ---------------------------------------

On September 29, 2014, Law No 20780 was enacted by
which certain changes are made to the Chilean tax system, such as: changes in the Income Tax Law, VAT Law and Tax Code. Also, on February 01, 2016 Law No 20899 was enacted to simplify and define the application of the above-mentioned tax
reform. With respect to income tax, two systems have been established:



| | i) | Attributable income system: the tax rate 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. The tax rate 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.

| | d) | Changes in the Income Tax Law in Colombia -
| | -- | -------------------------------------------

In December 2014 Law No 1739 was enacted amending
the Tax Code and introducing diverse temporary changes in Income Tax, CREE (Tax on income for equity) and includes the tax on wealth (Impuesto a la Riqueza). Major changes are as follows:



| | - | Setting the CREE tax rate at 9% and creating an incremental additional overrate effective until 2018, as follows: for fiscal 2015, 2016, 2017 and 2018 the applicable CREE tax overrate will be 5%, 6%, 8% and 9%,
respectively.
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | - | 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.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Based on the above, the Group has assessed the future realization of its temporary items underlying its deferred income tax based on the
application of the new tax rates and is determining the required adjustments that will result from the expected changes in tax rates.



| | e) | The income tax expense shown in the consolidated income statement comprises:

In December 2015 the subsidiary CAM Chile Spa sold its entire stake in CAM Brazil which gave rise to a tax
loss of S/119 million (23,863 million Chilean pesos). This tax loss mainly resulted from the higher tax cost of the shares in this subsidiary given the fact under Chilean tax laws, the historical cost of investments overseas should be adjusted
for changes in the exchange rates at each period-end; this difference is recognized as income or expense for tax purposes. In this sense, considering the weakening of the Chilean Peso against the U.S. dollar, the currency in which the investment was
acquired, tax cost was significant. The PPUA recognized for this tax loss was S/19.4 million.

VyV-DSD has reported tax losses in
fiscal 2015 as a result of the negative margin obtained from the higher costs incurred in project called Hidro Ñuble of S/111 million (22,205 million Chilean pesos) and for this reason it has recognized a PPUA of S/21.9 million.

| | g) | 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 2011 through 2015 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 2012 to 2014 and
those to be filed for fiscal year 2015 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 2013
and 2014 are open for tax audit by Colombian tax authorities; fiscal 2015 will be open for audit too. Colombian tax authorities are entitled to audit two consecutive years following the date the income tax return was filed.

| | h) | As established under regulations in force in Peru, for purposes of determining income tax and the general sales tax, transfer pricing must be taken into account for operations with related parties and/or tax havens,
which must have documentation and information supporting the methods and valuation criteria applied in their determination. Peruvian tax authorities are entitled to request such information from the taxpayer.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | i) | Temporary tax on net assets -
| | -- | -----------------------------

The temporary tax on net assets is applied by the companies
which operate in Peru, to third category income generators subject to the Peruvian Income Tax General Regime. Effective in the year 2012, the tax rate is 0.4%, applicable to the amount of the net assets exceeding S/1 million.

The amount effectively paid may be used as a credit against payments on account of income tax under the General Regime or against the
provisional tax payment of the income tax of the related period.



| | j) | The weighted-average tax rate was 35% (29.30% in 2014 and 30.7% in 2013). The higher income tax rate in relation with the previous year mainly reflects the lower consolidated pre-tax profits during 2015 and the net tax
adjustments not accepted by the Peruvian Tax Authorities are proportionally lower than what was determined for fiscal 2014.

|32 | BUSINESS COMBINATIONS
|-- | ---------------------



| | a) | 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, goodwill of US$36.1 million (equivalent to S/105.8 million) was determined.

In 2015 as part of the review of the provisional allocation of the purchase price, the following situations arose:



| | b) | The balance at December 31, 2014 of the consideration payable of US$15 million (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, according to the purchase agreement. This amount was fully paid in 2015.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c) | 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).

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 obtain 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 begins 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 fair 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
the weighted average forecast profits to be obtained by Morelco and the exercise rights of the option. The Company expects that purchase options are to be exercise 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 all risks have been included in the weighted estimates of future cash flows. At December 31, 2015 the liability is estimated to
be 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 (at December 31, 2014 it was S/113.8 million at a 1.65% discount rate). In 2015 the change in the liability
amount includes the passage of time component, of S/2.1 million that is included within financial expenses and an estimate updating component with an effect of S/18.6 million that is included within Other income and expenses in profit and loss (Note
21).



| | d) | 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 100.00% 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 presence in markets that present high growth potential as 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, 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 amount of goodwill was changed to US$2.2 million (equivalent to S/6.4 million).

| | e) | Acquisition of DSD Construcciones y Montajes S.A. (DSD)
| | -- | -------------------------------------------------------

In August 2013, through the
subsidiaries GyM Minería S.A., Ingeniería y Construcción Vial y Vives S.A. and GyM Chile S.p.A., the Group acquired control of DSD with the purchase of 85.95% of its equity shares. DSD is an entity domiciled in Chile whose main
economic activity is the execution of electromechanical works and assemblies in construction projects of oil refineries, pulp and paper, power plants and mining plants.

This acquisition is part of the Groups plan to increase its presence in markets that present high growth potential as in Chile, and in
attractive industries, such as mining and energy.

During the twelve-month period after the acquisition date, the Group reviewed the
allocation of the purchase price for the acquisition of DSD Construcciones y Montajes S.A. carried out in August 2014 and modified goodwill for a net decrease of S/1.7 million (net of tax impact of S/0.5 million and non-controlling interest of S/0.3
million) adjusting the values of fixed assets, intangibles, trade receivables, other receivables and contingent liabilities for S/0.4 million, S/1.9 million, S/0.2 million, S/3.5 million and S/3 million, respectively.

The consideration provided by GyM to purchase DSD Construcciones y Montajes S.A. amounted to US$37.2 million (equivalent to S/103.9
million). The final attribution of the price paid between fair values after the review period resulted in the recognition of goodwill for S/6.1 million which is illustrated below:

|34 | EARNINGS 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:

| | e) | Deconsolidation of subsidiaries
| | -- | -------------------------------

In 2014 the Group assessed its interest in the joint venture
Red Vial 1  Cusco, which was considered and reported as a subsidiary at December 31, 2013. As a result of this assessment, the Group concluded that the rights entitled in such business do not grant control, joint control or
significant influence. In addition Management ́s conclusion is that Company ́s interest in this business is that of a financial asset (receivable). In 2014, assets and liabilities of Red Víal 1 - Cusco previously
consolidated and the non-controlling interest amounted to S/2,284 which was eliminated.

In 2013 the Group assessed its interests in
Concesión La Chira S.A. and Logistica Quimica del Sur S.A.C (LQS). The interests in these concessions were accounted for as if they were under control of the Group (subsidiaries). Subsequent that assessment it was determined that the
interests correspond to a joint operation and joint venture, respectively under the provisions of IFRS 11. As of December 31, 2013 assets and liabilities of non-controlling interest amounted to S/12,535 for La Chira and S/6,842 for LQS.



| | f) | Dividends

Seguridad Energética del País y Desarrollo del Gasoducto Sur Peruano). In February 2016, the Company has partially received U$120 million of the total subscribed contract.

Supplementary Data (Unaudited)

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 relate 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 2014 and 2015 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.

|(2) | The revisions in reserve estimates are based on new information obtained as a result of drilling activities and workovers. During 2015, proved developed reserves of crude oil decreased due to the impact of the lower
price in reserve estimations, mainly in Block I. In 2015, natural gas proved reserves decreased as a result of reviews of Block I oil reserves.

| | 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 twelve month period
unweighted arithmetic average of the price as of the first day of each month within that twelve 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.
