Consolidated Financial Statements





For the Years Ended December 31, 2016, and 2015



---

Management Report

The annual report, including the consolidated financial statements and Managements Discussion and Analysis (MD&A), is the responsibility of the
management of the Company. The consolidated financial statements were prepared by management in accordance with International Financial Reporting Standards. Where alternative accounting methods exist, management has chosen those it considers most
appropriate in the circumstances. The significant accounting policies used are described in note 4 to the consolidated financial statements. Certain amounts in the financial statements are based on estimates and judgments relating to matters not
concluded by year-end. The integrity of the information presented in the financial statements is the responsibility of management. Financial information presented elsewhere in this annual report has been
prepared by management and is consistent with the information in the consolidated financial statements.

The board of directors is responsible for ensuring
that management fulfills its responsibilities and for providing final approval of the annual consolidated financial statements. The board has appointed an Audit and Risk Committee comprising four directors; none are officers or employees of the
Company or its subsidiaries. The Audit and Risk Committee meets at least four times each year to discharge its responsibilities under a written mandate from the board of directors. The Audit and Risk Committee meets with management and with the
external auditors to satisfy itself that it is properly discharging its responsibilities; reviews the consolidated financial statements, MD&A, and Independent Auditors Report; and examines other auditing and accounting matters. The Audit
and Risk Committee has reviewed the audited consolidated financial statements with management and discussed the quality of the accounting principles as applied and the significant judgments affecting the consolidated financial statements. The Audit
and Risk Committee has discussed with the external auditors the external auditors judgments of the quality of those principles as applied and the judgments noted above. The consolidated financial statements and MD&A have been reviewed by
the Audit and Risk Committee and approved by the board of directors of Stantec Inc.

The consolidated financial statements have been examined by the
shareholders auditors, Ernst & Young LLP, Chartered Professional Accountants. The Independent Auditors Report outlines the nature of their examination and their opinion on the consolidated financial statements of the Company.
The external auditors have full and unrestricted access to the Audit and Risk Committee, with or without management being present.

Managements Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining an adequate system of internal control over financial reporting. The 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 International Financial Reporting
Standards. Management conducted an evaluation of the effectiveness of the system of internal control over financial reporting based on the framework in Internal Control  Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (2013 framework). Based on this evaluation, management concluded that the Companys system of internal control over financial reporting was effective as at December 31, 2016.

Ernst & Young LLP, which has audited the consolidated financial statements of the Company for the year ended December 31, 2016, has also issued a
report on the effectiveness of the Companys internal control over financial reporting.

As permitted by published guidance of the U.S. Securities and
Exchange Commission (SEC), managements evaluation of and conclusions on the effectiveness of internal control over financial reporting did not include the internal controls of Bury Holdings, Inc.; MWH Global, Inc.; VOA Associates, Inc.;
Edwards and Zuck, P.C.; and Edwards and Zuck Consulting Engineers, D.P.C. acquisitions which are included in the Companys 2016 consolidated financial statements. The aggregate assets acquired were $818.7 million, representing 19.1% of the
Companys total assets as at December 31, 2016. The gross revenue earned from their dates of acquisition to December 31, 2016, constituted 32.3% of the Companys gross revenue for the year ended December 31, 2016.

Independent Auditors Report of Registered

Public Accounting Firm

To the
Board of Directors and Shareholders of Stantec Inc.:

We have audited the accompanying consolidated financial statements of Stantec Inc., which
comprise the consolidated statements of financial position as at December 31, 2016 and 2015, and the consolidated statements of income, comprehensive income, shareholders equity and cash flows for the years ended December 31, 2016
and 2015, and a summary of significant accounting policies and other explanatory information.

Managements Responsibility for the
Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated financial
statements in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, and for such internal control as management determines is necessary to enable the preparation of consolidated
financial statements that are free from material misstatement, whether due to fraud or error.

Auditors Responsibility

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with Canadian
generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance
about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence
about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditors judgment, including the assessment of the risks of material misstatement of the consolidated financial statements,
whether due to fraud or error. In making those risk assessments, the auditors consider internal control relevant to the entitys preparation and fair presentation of the consolidated financial statements in order to design audit procedures that
are appropriate in the circumstances. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, evaluating the appropriateness of accounting policies used and the
reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.

We
believe that the audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the
consolidated financial statements present fairly, in all material respects, the financial position of Stantec Inc. as at December 31, 2016 and 2015, and its financial performance and its cash flows for the years ended December 31, 2016 and
2015 in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

Other Matter

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Stantec Inc.s
internal control over financial reporting as at December 31, 2016, based on the criteria established inInternal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013
framework) and our report dated February 22, 2017 expressed an unqualified opinion on Stantec Inc.s internal control over financial reporting.

Independent Auditors Report on Internal Control over

Financial Reporting

(Under the standards of
the Public Company Accounting Oversight Board (United States))

To the Board of Directors and Shareholders of Stantec Inc.:

We have audited Stantec Inc.s internal control over financial reporting as at December 31, 2016, based on criteria established in Internal
ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). Stantec Inc.s management is responsible for maintaining effective internal control over
financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Managements Annual Report on Internal Control over Financial Reporting. Our responsibility is to express
an opinion on the Companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of
the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material
respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the
assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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 International Financial Reporting Standards as issued by the International Accounting Standards Board (IFRS). A companys internal control over
financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with IFRS, and that receipts and expenditures of the company are being made only in accordance with authorizations of
management and directors of the company; and (3) 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.

As indicated in the accompanying Managements Annual Report on Internal Control over Financial Reporting, managements assessment of and conclusion
on the effectiveness of internal control over financial reporting did not include the internal controls of Bury Holdings, Inc.; MWH Global, Inc.; VOA Associates, Inc.; Edwards and Zuck, P.C.; and Edwards and Zuck Consulting Engineers, D.P.C. which
are included in the 2016 consolidated financial statements of Stantec Inc. The total assets acquired from these specified acquisitions represented 19.1% of Stantec Inc.s consolidated total assets at December 31, 2016 and 32.3% of Stantec
Inc.s consolidated gross revenue for the year then ended not subject to managements assessment of and conclusion on the effectiveness of internal control over financial reporting. Our audit of internal control over financial reporting of
Stantec Inc. also did not include an evaluation of the internal control over financial reporting of these specified acquisitions.

In our opinion, Stantec
Inc. maintained, in all material respects, effective internal control over financial reporting as at December 31, 2016, based on the COSO criteria.

We also have audited, in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board
(United States), the consolidated statements of financial position of Stantec Inc. as at December 31, 2016 and 2015, and the consolidated statements of income, comprehensive income, shareholders equity and cash flows for the years ended
December 31, 2016 and 2015, and our report dated February 22, 2017, expressed an unqualified opinion thereon.

Notes to the Consolidated Financial Statements

1. CORPORATE INFORMATION

The consolidated financial statements of
Stantec Inc. (the Company) for the year ended December 31, 2016, were authorized for issue in accordance with a resolution of the Companys board of directors on February 22, 2017. The Company was incorporated under the Canada
Business Corporations Act on March 23, 1984. Its shares are traded on the Toronto Stock Exchange (TSX) and New York Stock Exchange (NYSE) under the symbol STN. The Companys registered office is located at 10160  112 Street,
Edmonton, Alberta. The Company is domiciled in Canada.

The Company is a provider of comprehensive professional services in the area of infrastructure and
facilities for clients in the public and private sectors. The Companys services include engineering, architecture, interior design, landscape architecture, surveying, environmental sciences, construction services, project management, and
project economics, from initial project concept and planning through to design, construction, commissioning, maintenance, decommissioning, and remediation.

2.
BASIS OF PREPARATION

These consolidated financial statements were prepared in accordance with International Financial Reporting Standards (IFRS) as
issued by the International Accounting Standards Board (IASB). The accounting policies adopted in these consolidated financial statements are based on IFRS effective as at December 31, 2016.

The consolidated financial statements have been prepared on a historical cost basis, unless otherwise stated in the significant accounting policies. The
consolidated financial statements are presented in Canadian dollars, and all tabular values are rounded to the nearest thousand ($000).

3. BASIS OF
CONSOLIDATION

The consolidated financial statements include the accounts of the Company, its subsidiaries, and its structured entities as at
December 31, 2016.

Subsidiaries and structured entities are fully consolidated from the date of acquisition, which is the date the Company obtains
control, and continue to be consolidated until the date that such control ceases. The financial statements of the subsidiaries and structured entities are prepared as at December 31, 2016. All intercompany balances are eliminated.

Joint ventures are accounted for using the equity method, and joint operations are accounted for by the Company recognizing its share of assets, liabilities,
revenue, and expenses of the joint operation.

4. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

a) Cash and cash equivalents

Cash and cash equivalents include cash
and unrestricted investments. Such investments are carried at fair value.

b) Property and equipment

Property and equipment are recorded at cost less accumulated depreciation and any impairment losses. Cost includes the cost of replacing parts of property and
equipment. When significant parts of property and equipment are required to be replaced in intervals, the Company recognizes such parts as individual assets with specific useful lives and depreciation, respectively. All other repair and maintenance
costs are recognized in the consolidated statements of income as incurred.



|                                                                 |  |      |  |             
|---------------------------------------------------------------- |  | ---- |  | ------------
|Notes to the Consolidated Financial Statements
December 31, 2016 |  | F-10 |  | Stantec Inc.



---

Depreciation is calculated at annual rates designed to write off the costs of assets over their estimated useful
lives as follows:



|                       |  |            |  |                                                                                              |  | 
|---------------------- |  | ---------- |  | -------------------------------------------------------------------------------------------- |  | 
|Engineering equipment  |  | 20% to 30% |  | Declining balance                                                                            |  | 
|Office equipment       |  | 20% to 30% |  | Declining balance                                                                            |  | 
|Leasehold improvements |  |            |  | Straight-line over term of lease to a maximum of 15 years or the improvements economic life |  | 
|Other                  |  | 10% to 30% |  | Declining balance                                                                            |  | 

The assets residual values, useful lives, and methods of depreciation are reviewed at each financial year-end and adjusted prospectively, if appropriate.

c) Intangible assets

Intangible assets acquired separately are measured on initial recognition at cost. The cost of a finite and indefinite intangible asset acquired in a business
combination is its fair value as at the date of acquisition. Following initial recognition, finite intangible assets are carried at cost less any accumulated amortization and any impairment losses and indefinite intangible assets are carried at cost
less any impairment loss.

The Companys intangible assets with finite lives are amortized over their useful economic lives on a straight-line basis.
The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at each financial year-end.

Intangible assets acquired from business combinations

The Companys policy is to amortize client relationships with finite lives over periods ranging from 10 to 15 years. Contract backlog and finite
trademarks are amortized over estimated lives of generally 1 to 3 years. Advantageous leasehold commitments are amortized over estimated lives of 1 to 10 years. The Company assigns value to acquired intangibles using the income approach, which
involves quantifying the present value of net cash flows attributed to the subject asset. This, in turn, involves estimating the revenues and earnings expected from the asset. Recognition of the contributory assets, such as workforce, working
capital, and property and equipment required and used to generate the expected after-tax earnings, is included since these assets also require a return based on their fair values. Expected earnings after
contributory charges and income taxes are discounted by the appropriate after-tax discount rate to arrive at the fair value.

Intangible assetsSoftware

For internally generated
software, research costs are expensed as incurred. Development expenditures on an individual project are recognized as an intangible asset when the Company can demonstrate



| |  |  | The technical feasibility of completing the intangible asset so that it will be available for use
| | - |  | -------------------------------------------------------------------------------------------------

| |  |  | Its intention to complete and its ability to use the asset
| | - |  | ----------------------------------------------------------

| |  |  | How the asset will generate future economic benefits
| | - |  | ----------------------------------------------------

| |  |  | The availability of resources to complete the asset
| | - |  | ---------------------------------------------------

| |  |  | The ability to reliably measure the expenditure during development
| | - |  | ------------------------------------------------------------------

Following the initial recognition of the
development expenditure as an asset, it is carried at cost less any accumulated amortization and any impairment losses. Amortization of the asset begins when development is complete and the asset is available for use. The Company amortizes certain
purchased and internally generated software on a straight-line basis over periods ranging from three to seven years.

The Company also incurs costs for
third-party internet-based cloud computing services. These costs are expensed as incurred in administrative and marketing expenses.

d) Leases

The determination of whether an arrangement is or contains a lease is based on the substance of the arrangement at the inception date. A lease is an agreement
whereby the lessor conveys to the lessee, in return for a payment or series of payments, the right to use an asset for an agreed period of time.



|                                                                 |  |      |  |             
|---------------------------------------------------------------- |  | ---- |  | ------------
|Notes to the Consolidated Financial Statements
December 31, 2016 |  | F-11 |  | Stantec Inc.



---

Finance leases, which transfer to the Company substantially all the risks and benefits incidental to ownership of
the leased items, are capitalized at the inception of the lease at the fair value of the leased asset or, if lower, at the present value of the minimum lease payments. Lease payments are apportioned between finance charges and reduction of the lease
liability, achieving a constant rate of interest on the remaining balance of the liability. Finance charges are recognized in the consolidated statements of income.

Leased assets are depreciated over their useful lives. However, if there is no reasonable certainty that the Company will obtain ownership of the asset by the
end of the lease term, the asset is depreciated over the shorter of either its estimated useful life or the lease term. The Companys finance leases are for certain office and automotive equipment and are depreciated on a 20%-to-30% declining balance basis. The Company also has finance leases for software, which are depreciated on a straight-line basis over periods ranging from three to seven
years.

Rental payments under operating leases are expensed evenly over the lease term.

From time to time, the Company enters into or renegotiates premises operating leases that result in receiving lease inducement benefits. These benefits are
accounted for as a reduction of rental expense over the terms of the associated leases. As well, from time to time, the Company enters into or renegotiates premises operating leases that include escalation clauses. The scheduled rent increases
pursuant to lease escalation clauses are recognized on a straight-line basis over the lease terms.

e) Investments in joint arrangements and associates

Each joint arrangement of the Company is classified as either a joint venture or joint operation based on the rights and obligations arising from the
contractual obligations between the parties to the arrangement. A joint arrangement that provides the Company with rights to the net assets of the arrangement is classified as a joint venture, and a joint arrangement that provides the Company with
rights to the individual assets and obligations arising from the arrangement is classified as a joint operation.

The Company accounts for a joint venture
using the equity method (described below). The Company accounts for a joint operation by recognizing its share of assets, liabilities, revenues, and expenses of the joint operation and combining them line by line with similar items in the
Companys consolidated financial statements.

Investments in associated companies, over which the Company is able to exercise significant influence
but not control, are accounted for using the equity method, which reflects the Companys investment at original cost plus postacquisition changes in the Companys share of the net assets of the associate. The share of the profit of
associates is recorded in the consolidated statements of income. Since this is profit attributable to the equity holders of the associate, it is profit after tax. Adjustments are made in the Companys consolidated financial statements to
eliminate its share of unrealized gains and losses resulting from transactions with its associates.

If the financial statements of associates or joint
arrangements are prepared for a date that is different from the Companys date, adjustments are made for the effects of significant transactions or events that occur between that date and the date of the Companys financial statements.
When necessary, adjustments are made to bring the accounting policies in line with the Companys.

f) Investments held for self-insured liabilities

In other financial assets, the Company has investments held for self-insured liabilities that are categorized as available for sale and are recorded
at fair value, with associated unrealized gains or losses reported in other comprehensive income until disposed of, at which time realized gains or losses are recognized in income. These investments consist of government and corporate bonds, equity
securities, and term deposits.

g) Provisions

General

Provisions are recognized when the Company has a present legal or constructive obligation as a result of a past event, it is probable that an outflow
of resources embodying economic benefits will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation. When the Company expects some or all of a provision to be reimbursedfor example, under an
insurance contractand when the reimbursement is virtually certain, the reimbursement is recognized as a separate asset. The expense relating to any provision is presented in the consolidated statements of income net of any reimbursement. If
the effect of the time value of money



|                                                                 |  |      |  |             
|---------------------------------------------------------------- |  | ---- |  | ------------
|Notes to the Consolidated Financial Statements
December 31, 2016 |  | F-12 |  | Stantec Inc.



---

is material, provisions are discounted using a current pretax rate that reflects, where appropriate, the risks specific to the liability. When discounting is used, the increase in the provision
due to the passage of time is recognized as a finance cost.

Provision for self-insured liabilities

The Company self-insures certain risks related to professional liability, automobile physical damages, and employment practices liability. The provision for
self-insured liabilities includes estimates of the costs of reported claims (including potential claims that are probable of being asserted) and is based on estimates of loss using assumptions made by management, including consideration of actuarial
projections. The provision for self-insured liabilities does not include unasserted claims where assertion by a third party is not probable.

The Company
invests funds to support the provision for self-insured liabilities. These investments are recorded at fair value in other financial assets as investments held for self-insured liabilities.

Provisions for claims

The Company has claims that are
not covered by its provisions for self-insured liabilities, including claims that are subject to exclusions under the Companys commercial and captive insurance policies. Provisions are recognized for these claims in accordance with the
preceding description of provisions under General.

Contingent liabilities recognized in a business combination

A contingent liability recognized in a business combination is initially measured at its fair value. Subsequently, it is measured in accordance with the
preceding description of provisions under General.

Onerous contracts

The Companys onerous contracts consist of lease exit liabilities and sublease losses. For lease exit liabilities, the Company accrues charges when it
ceases to use an office space under an operating lease arrangement. Included in the liability is the present value of the remaining lease payments offset by the present value of estimated future rental income.

From time to time, the Company may sublet a portion of office space that is under an operating lease arrangement. The Company accrues a liability, a sublease
loss, if the costs to be incurred under an operating lease will exceed the anticipated revenue on the sublease. Included in the liability is the present value of the remaining lease payments offset by the present value of the future rental income.

h) Foreign currency translation

The Companys
consolidated financial statements are presented in Canadian dollars, which is also the parent Companys functional currency. Each entity in the Company determines its own functional currency, and items included in the financial statements of
each entity are measured using that functional currency.

Transactions and balances

Transactions in foreign currencies (i.e., different than an entitys functional currency) are initially translated into the functional currency of an
entity using the foreign exchange rate at the transaction date. Subsequent to the transaction date, foreign currency transactions are measured as follows:



| |  |  | On the consolidated statements of financial position, monetary items are translated at the rate of exchange in effect at the reporting date. Non-monetary items at cost are
translated at historical exchange rates. Non-monetary items at fair value are translated at rates in effect at the date the fair value is determined. Any resulting realized and unrealized foreign exchange
gains or losses are included in income in the period incurred. The exception is unrealized foreign exchange gains and losses on non-monetary investments (equity investments) classified as available for sale,
which are included in other comprehensive income.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Revenue and expense items are translated at the exchange rate on the transaction date, except for depreciation and amortization, which are translated at historical exchange rates.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|                                                                 |  |      |  |

The Companys foreign operations are translated into its reporting currency (Canadian dollar) as follows:



| |  |  | Assets and liabilities are translated at the rate of exchange in effect at each consolidated statement of financial position date
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | Revenue and expense items (including depreciation and amortization) are translated at the average rate of exchange for the month
| | - |  | --------------------------------------------------------------------------------------------------------------------------------

The resulting unrealized exchange gains and losses on foreign subsidiaries are recognized in other comprehensive income.

i) Financial instruments

Initial recognition and subsequent
measurement

The Company classifies its financial instruments as follows:



| |  |  | Cash and cash equivalents and cash in escrow are classified as financial assets at fair value through profit and loss (FVPL) and are recorded at fair value, with realized and unrealized gains and losses reported in
income.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Trade and other receivables are classified as receivables and are initially accounted for at fair value and subsequently adjusted for any allowance for doubtful accounts, with allowances reported in administrative and
marketing expenses.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Investments held for self-insured liabilities, consisting of bonds, equity securities, and term deposits, are classified as financial assets available for sale and are recorded at fair value, with accumulated unrealized
gains and losses reported in other comprehensive income until disposed of; at this time, the realized gains and losses are recognized in other income for equity securities and in finance income for bonds and term deposits. Interest income is
recorded in finance income, and dividends are recorded in other income.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Trade and other payables are classified as other financial liabilities and are recorded at fair value and subsequently recorded at amortized cost using the effective interest rate (EIR) method. Realized gains and losses
are reported in income. The EIR method discounts estimated future cash payments or receipts through the expected life of a financial instrument, thereby calculating the amortized cost and subsequently allocating the interest income or expense over
the life of the instrument.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Long-term debts are classified as loans and borrowings and are initially recorded at fair value and subsequently recorded at amortized cost using the EIR method. EIR amortization and realized gains and losses are
reported in net finance expense.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Fair value

All financial assets are recognized initially at fair value plus directly attributable transaction costs, except for financial assets at FVPL, for which
transaction costs are expensed. Purchases or sales of financial assets are accounted for at trade dates. All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings, net of directly attributable
transaction costs.

After initial recognition, the fair values of financial instruments are based on the bid prices in quoted active markets for financial
assets and on the ask prices for financial liabilities. For financial instruments not traded in active markets, fair values are determined using appropriate valuation techniques, which may include recent
arms-length market transactions, reference to the current fair value of another instrument that is substantially the same, and discounted cash flow analysis; however, other valuation models may be used.
The fair values of the Companys derivatives are based on third-party indicators and forecasts. The fair values of cash and cash equivalents, cash in escrow, trade and other receivables, and trade and other payables approximate their carrying
amounts because of the short-term maturity of these instruments. The carrying amounts of bank loans approximate their fair values because the applicable interest rate is based on variable reference rates. The carrying amounts of other financial
assets and financial liabilities approximate their fair values except as otherwise disclosed in the consolidated financial statements.

Derivatives

From time to time, the Company enters into foreign currency forward contracts to manage risk associated with net operating assets or liabilities denominated in
foreign currencies. The Companys policy is not to use these derivatives for trading or speculative purposes. In addition, the Company enters into software licensing agreements that have foreign currencyembedded derivatives. During 2016,
these software licensing derivatives did not have a material impact on the Companys financial position or performance.

j) Impairment

The carrying amounts of the Companys assets or group of assets, other than deferred tax assets, are reviewed at each reporting date to determine whether
there is an indication of impairment. An asset may be impaired if there is objective evidence of impairment as a result of one or more events that have occurred after the initial recognition of the asset (referred to as a loss event) and
if that loss event has an impact on the estimated future cash flows of the financial asset. When an indication of impairment exists or annual impairment testing for an asset is required, the assets recoverable amount is estimated.

Trade and other receivables

The Company maintains an
allowance for doubtful accounts on trade receivables. The estimate is based on the best assessment of the collectibility of the related receivable balance based in part on the age of the outstanding receivables and the Companys historical
collection and loss experience. When the carrying amount of the receivable is reduced through the allowance, the reduction is recognized in administrative and marketing expenses in the consolidated statements of income.

Non-financial assets

For non-financial assets such as property and equipment, goodwill, investments in joint ventures and associates, and
intangible assets, the recoverable amount is the higher of an assets or cash-generating units (CGUs) value in use or its fair value less costs of disposal. The recoverable amount is determined for an individual asset, unless the
asset does not generate cash inflows that are largely independent of those from other assets or groups of assets. Where the carrying amount of an asset or CGU exceeds its recoverable amount, the asset is considered impaired and is written down to
its recoverable amount. To assess value in use, the estimated future cash flows are discounted to their present value using a pretax discount rate that reflects current market assessments of the time value of money and the risks specific to the
asset. To determine fair value less costs of disposal, an appropriate valuation model is used. The results of these valuation techniques are corroborated by the market capitalization of comparable public companies and arms-length transactions
of comparable companies. Impairment losses are recognized in the consolidated statements of income in those expense categories that are consistent with the nature of the impaired asset.

Goodwill is not amortized but is evaluated for impairment annually (as at October 1) or more frequently if circumstances indicate that an impairment may occur
or if a significant acquisition occurs between the annual impairment test date and December 31. The Company considers the relationship between its market capitalization and its book value, as well as other factors, when reviewing for indicators of
impairment. Goodwill is assessed for impairment based on the CGUs or group of CGUs to which the goodwill relates. Any potential goodwill impairment is identified by comparing the recoverable amount of a CGU or a group of CGUs to its carrying value
including the allocated goodwill. If the recoverable amount is less than its carrying value, an impairment loss is recognized.

An impairment loss of
goodwill is not reversed. For other assets, an impairment loss may be reversed if the estimates used to determine the recoverable amount have changed. The reversal is limited so that the carrying amount of the asset does not exceed its recoverable
amount or the carrying amount that would have been determined, net of amortization or depreciation, had no impairment loss been recognized for the asset in prior years. The reversal is recognized in the consolidated statements of income.

Available-for-sale financial investments

For equity investments classified as available for sale, objective evidence of impairment includes a significant or prolonged decline in the fair value of the
investment below its cost. Significant is evaluated against the original cost of the investment and prolonged against the period in which the fair value has been below its original cost.



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

---

Where there is evidence of impairment, the cumulative loss is removed from other comprehensive income and
recognized in the consolidated statements of income. Impairment losses on equity investments are not reversed through the consolidated statements of income; increases in their fair value after impairment are recognized directly in other
comprehensive income.

For debt instruments (such as bonds) classified as available for sale, the Company first assesses individually whether objective
evidence of impairment exists for debt instruments that are individually significant or collectively for debt instruments that are not individually significant. If an impairment loss has occurred, the amount recorded is the cumulative loss, measured
as the difference between the amortized cost and the current fair value, less any previously recognized impairment loss. This amount is removed from other comprehensive income and recognized in the consolidated statements of income.

Future interest income continues to be accrued based on the reduced carrying amount of the asset applying the rate of interest used to discount the future
cash flows for the purpose of measuring the impairment loss. If the fair value of a debt instrument increases in a subsequent year and the increase can be objectively related to an event occurring after the impairment loss was recognized, the
impairment loss is reversed in the consolidated statements of income.

k) Revenue recognition

While providing services, the Company incurs certain direct costs for subconsultants, subcontractors, and other expenditures that are recoverable directly from
clients. These direct costs are included in the Companys gross revenue. Since these direct costs can vary significantly from contract to contract, changes in gross revenue may not be indicative of the Companys revenue trends. Therefore,
the Company also reports net revenue, which is gross revenue less subconsultants, subcontractors, and other direct expenses.

Revenue is recognized to the
extent that it is probable that the economic benefits will flow to the Company and the revenue can be reliably measured. Revenue is measured at the fair value of the consideration received, excluding discounts, duty, and taxes collected from clients
that are reimbursable to government authorities. The Company assesses its revenue arrangements against specific criteria to determine if it is acting as a principal or an agent. The Company has concluded that it is acting as a principal in all of
its revenue arrangements.

Revenue from fixed-fee and variable-fee-with-ceiling contracts is recognized by referring to the stage of completion using the revenue cost approach. Stage of completion is measured using labor costs incurred to date as a percentage of
total estimated labor costs for each contract. Where the contract outcome cannot be measured reliably, revenue is recognized only to the extent that the expenses incurred are eligible to be recovered. Provisions for estimated losses on incomplete
contracts are made in the period that the losses are determined. Revenue from time-and-material contracts without stated ceilings is recognized as costs are incurred.
Revenue is calculated based on billing rates for the services performed.

Unbilled revenue represents work in progress that has been recognized as revenue
but has not yet been invoiced to clients. Billings in excess of costs represent amounts that have been invoiced to clients but not yet recognized as revenue.

l)
Employee benefits plans

Defined benefit plans

The Company sponsors defined benefit pension plans covering certain full-time employees and past employees, primarily in the United Kingdom. Benefits are based
on final compensation and years of service. Benefit costs (determined separately for each plan using the projected unit credit method) are recognized over the periods that employees are expected to render services in return for those benefits.

Remeasurements, comprising of actuarial gains and losses and the return on the plan assets (excluding interest), are recognized immediately in the
consolidated statements of financial position with a corresponding debit or credit to other comprehensive income in the period in which they occur. Remeasurements are not reclassified to net income in subsequent periods.

Past service costs are recognized in net income on the earlier of the date of the plan amendment or curtailment and the date that the Company recognizes
related restructuring costs.



|                                                                 |  |      |  |             
|---------------------------------------------------------------- |  | ---- |  | ------------
|Notes to the Consolidated Financial Statements
December 31, 2016 |  | F-16 |  | Stantec Inc.



---

Net interest is calculated by applying the discount rate to the net defined benefit liability or asset, adjusted
for benefit and contribution payments during the year. The Company recognizes the following changes in the net defined benefit obligations under administrative and marketing expenses in the consolidated statements of income: service costs comprising
current service costs, past service costs, gains and losses on curtailments and non-routine settlements; net interest expense or income; and administrative expenses paid directly by the pension plans.

Defined contribution plans

The Company also contributes
to group retirement savings plans and an employee share purchase plan. Certain plans are based on the amount of employee contributions and subject to maximum limits per employee. The Company accounts for defined contributions as an expense in the
period in which the contributions are made.

m) Taxes

Current income tax

Current income tax assets and
liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted at
the reporting date in the countries where the Company operates and generates taxable income.

Current income tax that relates to items recognized directly
in equity is recognized in equity and not in the consolidated statements of income. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and
establishes an uncertain tax liability where appropriate.

Deferred tax

Deferred tax is determined using the liability method for temporary differences at the reporting date between the tax bases of assets and liabilities and their
carrying amounts for financial reporting purposes. Deferred tax liabilities are generally recognized for all taxable temporary differences. Deferred tax assets are recognized for all deductible temporary differences, carryforward of unused tax
credits and unused tax losses, to the extent that it is probable that taxable profit will be available against which the deductible temporary differences and the carryforward of unused tax credits and unused tax losses can be utilized. Deferred
taxes are not recognized for the initial recognition of goodwill; the initial recognition of assets or liabilities, outside of a business combination, that affect neither accounting nor taxable profit; or the differences relating to investments in
associates and interests in joint ventures to the extent that the reversal can be controlled and it is probable that it will not reverse in the foreseeable future.

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable
profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are reassessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits
will allow the deferred tax asset to be recovered.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the
year when the asset is realized or the liability is settled and are based on tax rates and tax laws that have been enacted or substantively enacted at the reporting date.

Deferred tax relating to items recognized in equity is also recognized in equity. Deferred tax items are recognized in correlation to the underlying
transaction either in other comprehensive income or directly in equity.

Deferred tax assets and deferred tax liabilities are offset if a legally
enforceable right exists to set off tax assets against tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

Sales tax

Revenues, expenses, and assets, except trade
receivables, are recognized net of the amount of sales tax recoverable from or payable to a taxation authority. Trade receivables and trade payables include sales tax. The net amount of sales tax recoverable from or payable to a taxation authority
is included as part of trade receivables or trade payables (as appropriate) in the consolidated statements of financial position.



|                                                                 |  |      |  |

n) Share-based payment transactions

Under the Companys share option plan, the board of directors may grant to officers and employees remuneration in the form of share-based payment
transactions, whereby officers and employees render services as consideration for equity instruments (equity-settled transactions).

Under the
Companys deferred share unit plan, the directors of the board of the Company may receive deferred share units (DSUs) equal to one common share. Before 2014, the chief executive officer could also receive DSUs. For the restricted share unit
plan, senior vice presidents may be granted share units that are to be settled after a two-year period. Under the Companys long-term incentive plan, certain members of the senior leadership teams,
including the chief executive officer, are granted performance share units (PSUs) that vest and are to be settled after a three-year period. The DSUs, restricted share units (RSUs), and PSUs are share appreciation rights that can be settled only in
cash (cash-settled transactions).

Equity-settled transactions

The cost of equity-settled transactions awards is measured at fair value at the grant date using a Black-Scholes option-pricing model. The cost of
equity-settled transactions, together with a corresponding increase in equity, is recognized over the period in which the service conditions are fulfilled (the vesting period). For equity-settled transactions, the cumulative expense recognized at
each reporting date until the vesting date reflects the extent to which the vesting period has expired and reflects the Companys best estimate of the number of equity instruments that will ultimately vest. The expense or credit to income for a
period represents the movement in cumulative expense recognized as at the beginning and end of that period and is recorded in administrative and marketing expenses. No expense is recognized for awards that do not ultimately vest.

Cash-settled transactions

The cost of cash-settled
transactions is measured initially at fair value at the grant date using a Black-Scholes option-pricing model. This fair value is expensed upon issue with the recognition of a corresponding liability. The liability is remeasured to fair value at
each reporting date, up to and including the settlement date, with changes in fair value recognized in administrative and marketing expenses.

o) Earnings per
share

Basic earnings per share is computed based on the weighted average number of common shares outstanding during the year. Diluted earnings per
share is computed using the treasury stock method, which assumes that the cash that would be received on the exercise of options is applied to purchase shares at the average price during the year and that the difference between the number of shares
issued on the exercise of options and the number of shares obtainable under this computation, on a weighted average basis, is added to the number of shares outstanding. Antidilutive options are not considered in computing diluted earnings per share.

p) Business combinations and goodwill

Business combinations
are accounted for using the acquisition method. The cost of an acquisition is measured as the consideration transferred at fair value at the acquisition date. Any contingent consideration to be transferred by the Company is recognized at fair value
at the acquisition date. Subsequent changes to the fair value of the contingent consideration are recognized in other income. Acquisition costs are expensed when incurred in administrative and marketing expenses.

Goodwill is initially measured at cost, which is the excess of the consideration transferred over the fair value of a Companys net identifiable assets
acquired and liabilities assumed. If this consideration is lower than the fair value of the net assets acquired, the difference is recognized in income.

After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a
business combination is, from the acquisition date, allocated to each CGU or group of CGUs that is expected to benefit from the synergies of the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to those
units. Each CGU or group of CGUs represents the lowest level at which management monitors the goodwill.



|                                                                 |  |      |  |

q) Dividends

Dividends
on common shares are recognized in the Companys consolidated financial statements in the period the dividends are declared by the Companys board of directors.

5. SIGNIFICANT ACCOUNTING JUDGMENTS, ESTIMATES, AND ASSUMPTIONS

Preparation of the Companys consolidated financial statements requires management to make judgments, estimates, and assumptions that affect the reported
amounts of revenues, expenses, assets, and liabilities, as well as the disclosure of contingent liabilities at the end of the reporting year. However, uncertainty about these assumptions and estimates could result in outcomes that require a material
adjustment to the carrying amount of the asset or liability affected in future periods.

Discussed below are the key management judgments and assumptions
concerning the future and other key sources of estimation uncertainty at the reporting date that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year.

a) Revenue recognition

The Company accounts for its revenue in
accordance with IAS 11Construction Contracts, which requires estimates to be made for contract costs and revenues. Revenue from fixed-fee and variable-fee-with-ceiling contracts is recognized using the percentage of completion method based on the ratio of labor costs incurred to total estimated labor costs. Estimating total direct labor costs is
subjective and requires the use of managements best judgments based on the information available at that time. The Company also provides for estimated losses on incomplete contracts in the period in which such losses are determined. Changes in
the estimates are reflected in the period in which they are made and affect the Companys revenue and unbilled revenue.

b) Allowance for doubtful accounts

The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability to collect on its trade receivables. The
Company uses estimates in arriving at its allowance for doubtful accounts. The estimates are based on the age of the outstanding receivables and on the Companys historical collection and loss experience. Future collections of receivables that
differ from the Companys current estimates would affect the results of its operations in future periods as well as the Companys trade receivables and administrative and marketing expenses.

c) Provision for self-insured liabilities

The Company self-insures
certain risks, including professional liability, automobile liability, and employment practices liability. The accrual for self-insured liabilities includes estimates of the costs of reported claims and is based on estimates of loss using
managements assumptions, including consideration of actuarial projections. These estimates of loss are derived from loss history that is then subjected to actuarial techniques to determine the proposed liability. Estimates of loss may vary
from those used in the actuarial projections and result in a larger loss than estimated. Any increase in loss would be recognized in the period in which the loss is determined and increase the Companys self-insured liabilities and reported
expenses.

d) Share-based payment transactions

The Company
measures the cost of share-based payment transactions by reference to the fair value of the equity instruments at the grant date. Estimating fair value for share-based payment transactions requires determining the most appropriate valuation model,
which is dependent on the terms and conditions of the grant. The Company has chosen the Black-Scholes option-pricing model for equity-settled and cash-settled share-based payment transactions.

Estimating fair value also requires determining the most appropriate inputs to the valuation modelincluding volatility in the price of the
Companys shares, a risk-free interest rate, and the expected hold period to exerciseand making assumptions about them. The expected volatility is based on the historical volatility of the Companys shares over a period commensurate
with the expected term of the share option. The risk-free interest rate for the expected life of the options is based on the yield available on government bonds, with an approximate equivalent remaining term at the time of the grant. Historical data
is used to estimate the expected life of the option. As well, the Company estimates its forfeiture rate for equity-settled transactions based on historical experience to determine the



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

---

compensation expense arising from the share-based awards. Changes to estimates are recorded in the period in which they are made and would affect the Companys administrative and marketing
expenses, contributed surplus, and other liabilities.

e) Business combinations

In a business combination, the Company may acquire certain assets and assume certain liabilities of an acquired entity. The estimate of fair values for these
transactions involves judgment to determine the fair values assigned to the tangible and intangible assets (i.e., backlog, client relationships, and favorable and unfavorable leases) acquired and the liabilities assumed on the acquisition.
Determining fair values involves a variety of assumptions, including revenue growth rates, expected operating income, and discount rates. During a measurement period, not to exceed one year, adjustments of the initial estimates may be required to
finalize the fair value of assets acquired and liabilities assumed. After the measurement period, a revision of fair value may impact the Companys net income.

f) Impairment of non-financial assets

Impairment exists when the carrying amount of an asset or CGU exceeds its recoverable amount, which is the higher of its fair value less costs of disposal or
its value in use. Fair value less costs of disposal is based on available data from binding sales transactions in an arms-length transaction of similar assets or observable market prices less incremental
costs for disposing of the asset. In the absence of this data, other valuation techniques can be used to estimate fair value less costs of disposal. The value in use calculation is based on a discounted cash flow model. The cash flows are derived
from budgets over an appropriate number of years and do not include restructuring activities that the Company is not yet committed to or significant future investments that will enhance the assets performance of the CGU being tested.

When based on a discounted cash flow methodology, the recoverable amount is most sensitive to the expected future cash inflows, the growth rate used for
extrapolation purposes, and the discount rate. To arrive at cash flow projections, the Company uses estimates of economic and market information over the projection period, including growth rates in revenues, estimates of future expected changes in
operating margins, and cash expenditures. Other significant estimates and assumptions include future estimates of capital expenditures and changes in future working capital requirements.

g) Employee benefit plans

The cost of the defined benefit pension
plans and the present value of the pension obligations are determined separately for each plan using actuarial valuations. An actuarial valuation involves making various assumptions that may differ from actual future developments. These include
determining the discount rate, mortality rates, future salary increases, inflation, and future pension increases. Due to the complexities involved in the valuation and its long-term nature, the defined benefit obligation and cost are highly
sensitive to changes in these assumptions, particularly to the discount and mortality rates (although a portion of the pension plans has protection against improving mortality rates by utilizing guaranteed annuity rate contracts with an insurance
company). All assumptions are reviewed annually.

In determining the appropriate discount rate, management considers the interest rates of corporate bonds
in currencies consistent with the currencies of the post-employment obligation with an AA rating or above, as set by an internationally acknowledged rating agency, and extrapolated as needed along the yield curve to correspond with the
expected term of the benefit obligation.

The mortality rate is based on publicly available information in the actuarial professions publications
plus any special geographical or occupational features of each plans membership. Mortality tables tend to change only at intervals in response to demographic changes. Future salary increases reflect the current estimate of management. Pension
increases are calculated based on the terms of the individual plans and estimated future inflation rates.

h) Fair value of financial instruments

When the fair value of financial assets and financial liabilities recorded in the consolidated statements of financial position cannot be derived from active
markets, it is determined using valuation techniques, including the discounted cash flow model. The inputs to these models are taken from observable markets if possible, but when this is not feasible, a degree of judgment is required to establish
fair values. The judgments include considering inputs such as liquidity risk, credit risk, and volatility. Changes in assumptions about these factors could affect the reported fair value of financial instruments and reported expenses and income.

i) Taxes

Uncertainties
exist with respect to the interpretation of complex tax regulations and the amount and timing of deferred taxable income. The Companys income tax assets and liabilities are based on interpretations of income tax legislation across various
jurisdictions, primarily in Canada and the United States. The Companys effective tax rate can change from year to year based on the mix of income among different jurisdictions, changes in tax laws in these jurisdictions, and changes in the
estimated value of deferred tax assets and liabilities. The Companys income tax expense reflects an estimate of the taxes it expects to pay for the current year, as well as a provision for changes arising in the values of deferred tax assets
and liabilities during the year. The tax value of these assets and liabilities is impacted by factors such as accounting estimates inherent in these balances, managements expectations about future operating results, previous tax audits, and
differing interpretations of tax regulations by the taxable entity and the responsible tax authorities. Differences in interpretation may arise for a wide variety of issues, depending on the conditions prevailing in the respective legal
entitys domicile. On a regular basis, management assesses the likelihood of recovering value from deferred tax assets, such as loss carryforwards, as well as from deferred tax depreciation of capital assets, and adjusts the tax provision
accordingly.

Deferred tax assets are recognized for all unused tax losses to the extent that it is probable that taxable profit will be available against
which the losses can be utilized. Significant management judgment is required to determine the amount of deferred tax assets that can be recognized based on the likely timing and the level of future taxable profits, together with future tax-planning strategies. If estimates change, the Company may be required to recognize an adjustment to its deferred income tax asset or liability and income tax expense.

j) Interests in other entities

The Company determines whether it
has control over another entity by making judgments about what the relevant activities of that entity are and which party or parties have power to direct those activities, as well as whether the Company is exposed to variable returns of the entity.
The Company assesses whether it has control, significant influence, or joint control over an entity based on the individual facts and circumstances of each agreement. In the case of a joint arrangement, the Company makes judgments to determine if
the arrangement is a joint venture or joint operation, including whether it has rights to the individual assets or liabilities or to the net assets of the entity and whether unanimous consent is required to make decisions about relevant activities.

6. RECENT ACCOUNTING PRONOUNCEMENTS AND CHANGES TO ACCOUNTING POLICIES

Recently adopted

The following amendments have been adopted by the
Company effective January 1, 2016. The adoption of these amendments did not have an impact on the financial position or performance of the Company.



| |  | In May 2014, the IASB issued Accounting for Acquisitions of Interests in Joint Operations (Amendments to IFRS 11). The amendments provide guidance on accounting for acquisitions of interests in joint operations
in which the activity constitutes a business, as defined by IFRS 3 Business Combinations(IFRS 3). The acquirer applies all principles on business combinations accounting in IFRS 3 and other IFRSs, except for those principles that conflict
with the guidance in IFRS 11 Joint Arrangements. In addition, the acquirer must disclose the information required by IFRS 3 and other IFRSs for business combinations.

Future adoptions

The listing below includes standards, amendments,
and interpretations that the Company reasonably expects to be applicable at a future date and intends to adopt when they become effective. The Company is currently considering the impact of adopting these standards, amendments, and interpretations
on its consolidated financial statements and cannot reasonably estimate the effect at this time unless specifically mentioned below.

| |  | In May 2014, the IASB issued IFRS 15 Revenue from Contracts with Customers(IFRS 15). In April 2016, the IASB issued amendments to clarify the standard and provide additional transition relief for modified
contracts and completed contracts. IFRS 15 applies to all revenue contracts with customers and provides a model for the recognition and measurement of the sale of some non-financial assets such as property,
plant, and equipment, and intangible assets. It sets out a five-step model for revenue recognition and applies to all industries. The core principle is that revenue should be recognized to depict the transfer of promised goods or services to
customers in an amount that reflects the consideration that the entity expects to be entitled to in exchange for those goods or services. IFRS 15 requires numerous disclosures, such as the disaggregation of total revenue, disclosures about
performance obligations, changes in contract asset and liability account balances, and key judgments and estimates. The Company has established a cross-functional IFRS 15 implementation team that provides regular updates to the Audit and Risk
Committee, including reports on the progress made on the implementation projects detailed work plan.

Major provisions
of IFRS 15 include determining which goods and services are distinct and require separate accounting (performance obligations), determining the total transaction price, estimating and recognizing variable consideration, identifying and accounting
for contract modifications, and determining whether revenue should be recognized at a point in time or over time (including guidance on measuring the stage of completion). The Company is currently assessing the potential effect of these requirements
on its consolidated financial statements. It is also in the process of formulating policies and practices for estimating variable consideration and applying the constraint thereto. At this time, the Company expects to continue to recognize revenue
over time for fixed-fee and variable-fee-with-ceiling contracts by referring to the stage of completion. For time-and-material contracts without stated ceilings, the Company is currently assessing whether a practical expedient could be applied which would allow the recognition of
revenue in the amount for which it has the right to invoice, consistent with current practices for such contracts. As the Companys assessment of IFRS 15 is in process, the above may not fully describe the potential effect of IFRS 15 on the
Companys accounting policies and is subject to change with new facts and circumstances.

The mandatory effective date of IFRS 15 is
January 1, 2018, with earlier application permitted. This standard may be adopted using a full retrospective or modified retrospective approach. The Company has not yet selected which transition method it will apply or quantified the financial
reporting impact of adopting this standard.



| |  | In July 2014, the IASB issued IFRS 9 Financial Instruments(IFRS 9) to introduce new requirements for the classification and measurement of financial assets and financial liabilities, including derecognition.
IFRS 9 requires that all financial assets be subsequently measured at amortized cost or fair value. The new standard also requires that changes in fair value attributable to a financial liabilitys credit risk be presented in other
comprehensive income, rather than in profit or loss. In addition, it includes a single expected-loss impairment model and a reformed approach to hedge accounting. This standard is effective on or after January 1, 2018, on a retrospective basis
subject to certain exceptions.
|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Company is in the process of completing an initial diagnostic assessment on IFRS 9. As a
result, the Company is assessing the impact the new expected-loss impairment model will have on the timing of recognition of allowance for doubtful accounts. The Company has investments held for self-insured liabilities including equity securities
and bonds. The Company is in the process of evaluating whether to classify these equities at fair value through profit and loss (FVTPL) or at fair value through other comprehensive income (FVTOCI). If the election for FVTOCI is chosen, any
subsequent gains or losses on disposal will not be recycled to income. In addition, these equity securities will no longer require an impairment test under either option. With regards to bonds, the Company is in the process of determining whether
they will be classified at amortized cost, FVTOCI, or at FVTPL.



| |  | In January 2016, the IASB issued IFRS 16 Leases(IFRS 16) which requires lessees to recognize assets and
liabilities for most leases. Lessees will have a single accounting model for all leases, with certain exemptions. For lessors, there is little change to the existing accounting in IAS 17 Leases.The new standard is effective January 1,
2019, with limited early application permitted. The new standard permits lessees to use either a full

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



| |  | In January 2016, the IASB issued Recognition of Deferred Tax Assets for Unrealized Losses (Amendments to IAS 12).The amendments clarify requirements for the recognition of deferred tax assets for unrealized
losses on debt instruments measured at fair value. These amendments are effective January 1, 2017, on a retrospective basis subject to certain exceptions.
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | In January 2016, the IASB issued Disclosure Initiative (Amendments to IAS 7). These amendments clarify IAS 7 in order to improve information provided to users of financial statements about an entitys
financing activities. These amendments are effective January 1, 2017, with earlier application permitted.
|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | In June 2016, the IASB issued Classification and Measurement of Share-based Payment Transactions (Amendments to IFRS 2). The amendments clarify how to account for the effects of vesting and non-vesting conditions on the measurement of cash-settled share-based payments, share-based payment transactions with a net settlement feature for withholding tax obligations, and a modification to the terms and
conditions of a share-based payment that changes the classification of the transaction from cash-settled to equity-settled. This amendment is effective on or after January 1, 2018, with earlier application permitted.

Reporting Standards(IFRS 1), IFRS 12 Disclosure of Interests in Other Entities(IFRS 12), and IAS 28 Investments in Associates and Joint Ventures(IAS 28). The amendment to IFRS 12 is effective January 1, 2017, on a
retrospective basis. The amendments to IFRS 1 and IAS 28 are effective January 1, 2018, on a retrospective basis.

| |  | In December 2016, the International Financial Reporting Interpretations Committee (IFRIC) issued an interpretation IFRIC 22 Foreign Currency Transactions and Advance Consideration(IFRIC 22). This interpretation
clarifies that for non-monetary assets or non-monetary liabilities, the transaction date is the date used to determine the exchange rate on which a company initially
recognizes a prepayment or deferred income arising from an advance consideration. The interpretation is effective January 1, 2018, and entities may use either a retrospective or prospective approach on transition, with earlier application
permitted.

7. BUSINESS ACQUISITIONS

Acquisitions are accounted for under the acquisition method of accounting and the results of operations since the respective dates of acquisition are included
in the consolidated statements of income. From time to time, as a result of the timing of acquisitions in relation to the Companys reporting schedule, certain estimates of fair values of assets and liabilities acquired may not be finalized at
the initial time of reporting. These estimates are completed after the vendors final financial statements and income tax returns have been prepared and accepted by the Company, after detail project portfolio reviews are performed, and when the
valuations of intangible assets and other assets and liabilities acquired are finalized. The preliminary fair values are based on managements best estimates of the acquired identifiable assets and liabilities at the acquisition date. During a
measurement period not to exceed one year, adjustments to the initial estimates may be required to finalize the fair value of assets and liabilities acquired. The Company will revise comparative information if these measurement period adjustments
are material.

The consideration paid for acquisitions may be subject to price adjustment clauses included in the purchase agreements and may extend over
a number of years. At each consolidated statement of financial position date, these price adjustment clauses are reviewed. This may result in an increase in or a reduction of the notes payable consideration (recorded on the acquisition date) to
reflect either more or less non-cash working capital than was originally recorded. Since these adjustments are a result of facts and circumstances occurring after the acquisition date, they are not considered
measurement period adjustments.

For some acquisitions, additional payments may be made to the employees of an acquired company that are based on the
employees continued service over an agreed time period. These additional payments are not included in the purchase price. They are expensed as compensation when services are provided by the employees.

Measurement period adjustments

The
preliminary fair values of the net assets recognized in the Companys consolidated financial statements were based on managements best estimates of the acquired identifiable assets and liabilities at the acquisition date. At
December 31, 2016, management has finalized the fair value assessment for the following assets and liabilities acquired from MWH: other financial assets, long-term debt, net employee defined benefit liability, and other financial liabilities.
For all other assets and liabilities acquired from the MWH acquisition the fair value estimates are still preliminary. As well, for all other acquisitions (Bury, Edwards & Zuck, VOA and Arch|TB) the fair value estimates are still
preliminary pending the preparation of their final tax returns, a detailed review of their project portfolio, and the valuation of intangible assets and other assets and liabilities. From the date of acquisition to December 31, 2016,
adjustments to acquisitions were identified as follows.

In September 2016, the Company obtained actuarial valuations of its defined benefit pension plans (the Plans) at May 6, 2016 (the date of the MWH
acquisition). The fair value of the Plans was $43,823,000, which was $15,382,000 more than the preliminary estimate. As a result, the Company revised the purchase price allocation for MWH by increasing the net employee defined-benefit liability by
$15,382,000, deferred tax assets by $2,835,000, and goodwill by $12,547,000.

Management is in the process of finalizing the valuation of acquired
intangibles related to the MWH acquisition. As a result, the Company revised the purchase price allocation for MWH by increasing client relationships by $36,518,000 and software by $13,991,000, and decreasing backlog by $12,713,000, other
intangibles by $601,000, deferred tax assets by $13,341,000, and goodwill by $23,854,000.

Management is in the process of performing a detailed review of
MWHs major projects portfolio and has identified that, for certain projects, the cost-to-complete estimates for revenue recognition, provisions for receivables,
and project claims did not reflect all the facts and circumstances at the acquisition date. Based on the review performed to date, the Company revised the purchase price allocation for MWH by decreasing the fair value of accounts receivable by
$4,151,000 and costs in excess of billing by $3,347,000, and increasing billings in excess of costs by $8,005,000, trade and other payables by $2,340,000 provisions by $4,654,000, deferred tax assets by $5,495,000, and goodwill by $17,002,000.

Management is in the process of finalizing the income tax returns for MWH and assessing uncertain tax liabilities at May 6, 2016. As a result, the
Company revised the preliminary purchase price for MWH by increasing the estimates used for the fair value of deferred tax assets by $6,715,000 and investment tax credits by $10,807,000 and decreasing other liabilities by $2,506,000, trade and other
receivables by $2,984,000, current income taxes recoverable by $9,218,000 and goodwill by $7,826,000.

Other acquisitions

Management has completed a detailed review of Kellogg Brown & Root Services, Inc.s (KBR) major projects portfolio and has identified that, for
certain projects, the cost-to-complete estimates for revenue recognition and provisions for claims did not reflect all the facts and circumstances at the acquisition
date. Based on the review performed to date, the Company revised the purchase price allocation for KBR by increasing billings in excess of costs by $597,000, provisions by $4,844,000, and goodwill by $6,441,000 and decreasing deferred tax assets by
$1,000,000. Measurement period adjustments impacting goodwill for all other acquisitions were immaterial.

For all the above measurement period
adjustments from the date of acquisition to December 31, 2016, management does not consider the impact to net income and other comprehensive income to be material for restating prior periods.

Other information

Trade receivables assumed from acquired companies
are recognized at fair value at the time of acquisition. Trade receivables acquired from MWH had a fair value of $209,325,000 and gross value of $219,265,000. In 2016, trade receivables acquired from other companies had a fair value of $54,111,000
and gross value of $59,390,000.

Goodwill consists of the value of expected synergies arising from an acquisition, the expertise and reputation of the
assembled workforce acquired, and the geographic location of the acquiree. No amount of goodwill and intangible assets resulting from the MWH acquisition is deductible for income tax purposes. For all other acquisitions completed during 2016,
$110,214,000 is deductible for income tax purposes.

The fair values of provisions are determined at the acquisition date. These liabilities relate to
claims that are subject to legal arbitration and onerous contracts. The Company assumed $16,493,000 in provisions for claims relating to MWH. For all other acquisitions completed during 2016, the Company assumed $7,146,000 in provisions. At the
reporting date, provisions for claims outstanding relating to all prior acquisitions were reassessed and determined to be $31,037,000 based on their expected probable outcome. Certain of these claims are indemnified by the acquiree (note 14).

The Company estimates that gross revenue earned since the date of acquisition for MWH is $1,293,110,000 and for all other acquisitions completed during 2016
is $95,741,000. The Company is in the process of integrating the

operations and systems of MWH and has substantially integrated the other acquisitions; therefore, it is impracticable to disclose the acquirees earnings in the Companys consolidated
financial statements since the acquisition date.

If the business combinations that occurred in 2016 had taken place at the beginning of 2016, gross
revenue from continuing operations for 2016 would have been $4,984,600,000 and profit from continuing operations would have been $136,614,000.

In 2016,
directly attributable acquisition-related costs of $14,110,000 for MWH and $438,000 for all other acquisitions have been expensed and are included in administrative and marketing expenses. These costs consist primarily of legal, accounting, and
financial advisory fees and costs directly related to the acquisitions.

The Company maintains an allowance for estimated losses on trade receivables. The estimate is based on the best assessment of
the collectibility of the related receivable balance, which is determined in part based on the age of the outstanding receivables and the Companys historical collection and loss experience.

The following table provides a reconciliation of changes to the Companys allowance for doubtful accounts.

Goodwill arising from acquisitions includes factors such as the expertise and reputation of the assembled workforce acquired,
the geographic location of the acquiree, and the expected synergies.

CGUs are defined based on the smallest identifiable group of assets that generates
cash inflows that are largely independent of the cash inflows from other assets or groups of assets. Other factors are considered, including how management monitors the entitys operations. In 2015 and the first quarter of 2016, the Company had
three CGUs: Canada, the United States, and International. Effective the second quarter of 2016, in connection with the MWH acquisition, the Company has six CGUs. Three of the six CGUs are grouped into Consulting ServicesGlobal for the purposes
of allocating goodwill and impairment testing. The Company does not monitor goodwill at, or allocate goodwill to, its business operating units.

On
October 1, 2016, and October 1, 2015, the Company performed its annual goodwill impairment test in accordance with its policy described in note 4. Based on the results of the 2016 and 2015 tests, the Company concluded that the recoverable
amount of each CGU or group of CGUs exceeded its carrying amount and, therefore, goodwill was not impaired.

Goodwill is allocated to each CGU or group of
CGUs as follows:

Management believes that the methodology used to test impairment of goodwill, which involves a significant number of judgments
and estimates, provides a reasonable basis for determining whether an impairment has occurred. Many factors used to determine whether goodwill is impaired are outside of managements control and involve inherent uncertainty. Therefore, actual
results could differ from those estimated.

Valuation techniques

When performing the goodwill impairment test, if the carrying amount of a CGU or group of CGUs is higher than its recoverable amount, an impairment charge is
recorded as a reduction in the carrying amount of the goodwill on the consolidated statements of financial position and recognized as a non-cash impairment charge in income.

The Company estimates the recoverable amount by using the fair value less costs of disposal approach. It
estimates fair value using market information and discounted after-tax cash flow projections, which is known as the income approach. The income approach uses a CGUs projection of estimated operating
results and discounted cash flows based on a discount rate that reflects current market conditions and the risk of achieving the cash flows. The Company uses cash flow projections covering a five-year period from financial forecasts approved by
senior management. For its October 1, 2016, and October 1, 2015, impairment tests, the Company discounted the cash flows for each CGU or group of CGUs using an after-tax discount rate ranging from
9.0% to 13.7%. To arrive at cash flow projections, the Company used estimates of economic and market information over the projection period (note 5).

The
Company validates its estimate of the fair value of each CGU or group of CGUs under the income approach by comparing the resulting multiples to multiples derived from comparable public companies and comparable company transactions. The Company
reconciles the total fair value of all CGUs with its market capitalization to determine if the sum is reasonable. If the reconciliation indicates a significant difference between the external market capitalization and the fair value of the CGUs or
group of CGUs, the Company reviews and adjusts, if appropriate, the discount rate of the CGU or group of CGUs and considers whether the implied acquisition premium is reasonable in light of current market conditions. The fair value measurement was
categorized as a level 3 fair value based on the significant inputs in the valuation technique used (note 25).

If market and economic conditions
deteriorate or if volatility in the financial markets causes declines in the Companys share price, increases the weighted average cost of capital, or changes valuation multiples or other inputs to its goodwill assessment, the Company may need
to test its goodwill for impairment between its annual test dates. In addition, changes in the numerous variables associated with the judgments, assumptions, and estimates made by management in assessing the fair value could cause them to be
impaired. Goodwill impairment charges are non-cash charges that could have a material adverse effect on the Companys consolidated financial statements but in themselves do not have any adverse effect on
its liquidity, cash flows from operating activities, or debt covenants and will not have an impact on its future operations.

Key assumptions

The calculation of fair value less costs of disposal is most sensitive to the following assumptions:



| |  |  | Operating margins based on actual experience and managements long-term projections.
| | - |  | ------------------------------------------------------------------------------------



| |  |  | Discount rates reflecting investors expectations when discounting future cash flows to a present value, taking into consideration market rates of return, capital structure, company size, and industry risk. If
necessary, a discount rate is further adjusted to reflect risks specific to a CGU or group of CGUs when future estimates of cash flows have not been adjusted.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Growth rate estimates based on actual experience and market analysis. Projections are extrapolated beyond five years using a growth rate that typically does not exceed 3.0%.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Sensitivity to changes in assumptions

As at October 1, 2016,
the recoverable amount of each CGU and group of CGUs exceeded their carrying amount. For the assessment of fair value less costs of disposal, management believes that no reasonably possible change in any of the above key assumptions would have
caused the carrying amount of a CGU or group of CGUs to exceed its recoverable amount.

Once an intangible asset is fully amortized, the gross carrying amount and related accumulated amortization are removed from
the accounts. A $10,433,000 trademark intangible asset with an indefinite life has been recorded in Other. Included in Software are finance leases with a net book value of $23,018,000 (2015  $22,560,000) and $117,000 (2015  $1,099,000)
in internally generated software that is not ready for use and, therefore, is not being amortized.

In accordance with its accounting policies in note 4,
the Company tests intangible assets for recoverability when events or changes in circumstances indicate that their carrying amount may not be recoverable. To determine indicators of impairment of intangible assets, the Company considers external
sources of information such as prevailing economic and market conditions and internal sources of information such as the historical and expected financial performance of the intangible assets. If indicators of impairment are present, the Company
determines recoverability based on an estimate of discounted cash flows, using the higher of either the value in use or the fair value less costs of disposal methods. The measurement of impairment loss is based on the amount that the carrying amount
of an intangible asset exceeds its recoverable amount. As part of the impairment test, the Company updates its future cash flow assumptions and estimates, including factors such as current and future contracts with clients, margins, market
conditions, and the useful lives of the assets. During 2016, the Company concluded that there were no material indicators of impairment to intangible assets.

Notes payable

Notes payable
consists primarily of notes payable for acquisitions (note 7). The weighted average rate of interest on the notes payable at December 31, 2016, was 3.45% (2015  3.63%). The notes may be supported by promissory notes and are due at various
times from 2017 to 2019. The aggregate maturity value of the notes at December 31, 2016, was $129,413,000 (2015  $126,840,000). At December 31, 2016, $122,333,000 (US$91,110,000) (2015  $117,282,000 (US$84,741,000)) of the
notes carrying amount was payable in US funds.

Revolving credit facilities and term loan

On May 6, 2016, the Company entered into an agreement for new $1.25 billion syndicated senior secured credit facilities (New Credit Facilities)
consisting of a senior secured revolving credit facility in the maximum amount of $800 million and a $450 million senior secured term loan in three tranches. This agreement allows the Company access to an additional $200 million,
subject to approval, under the same terms and conditions. The revolving credit facility expires on May 6, 2020, and may be repaid from time to time at the option of the Company. The facility is available for future acquisitions, working capital
needs, and general corporate purposes. Tranches A and B of the term loan were drawn in Canadian funds of $150 million each (due May 6, 2018, and May 6, 2019, respectively), and tranche C was drawn in US funds of $116.7 million
(due May 6, 2020). The term loan was recorded net of transaction costs of $3,341,000, which are amortized over the life of the three tranches.

The
New Credit Facilities may be drawn in Canadian dollars as either a prime rate loan or a bankers acceptance; in US dollars as either a US base rate or a LIBOR advance; or, in the case of the revolving credit facility, in sterling or euros as a
LIBOR advance; and by way of letters of credit. Depending on the form under which the credit facilities are accessed, rates of interest vary between Canadian prime, US base rate, and LIBOR or bankers acceptance rates, plus specified basis
points. The specified basis points vary, depending on the Companys leverage ratio (a non-IFRS measure), from 0 to 175 for Canadian prime and US base rate loans, and from 100 to 275 for bankers
acceptances, LIBOR advances, and letters of credit. As security for the obligations under these facilities, the Company and certain of its subsidiaries granted the lenders a first-ranking security interest over all present and after-acquired assets,
property, and undertakings subject to customary carve-outs. The New Credit Facilities contain restrictive covenants (note 27).

The Company previously entered into an agreement for a $350 million revolving credit facility expiring in
August 2018. This facility allowed the Company access to an additional $150 million under the same terms and conditions on approval from its lenders. Depending on the form under which the credit facility was accessed, rates of interest varied
between Canadian prime, US base rate, and LIBOR or bankers acceptance rates, plus specified basis points. The specified basis points varied, depending on the Companys level of consolidated debt to EBITDA (a
non-IFRS measure), from 20 to 125 for Canadian prime and US base rate loans, and from 120 to 225 for bankers acceptances, LIBOR loans, and letters of credit. EBITDA represents net income before interest
expense, income taxes, depreciation of property and equipment, amortization of intangible assets, and goodwill and intangible impairment. This revolving credit facility was repaid with the proceeds from the New Credit Facilities.

At December 31, 2016, $114,130,000 (US$85,000,000) of the revolving credit facility was payable in US funds and $302,000,000 was payable in Canadian
funds. At December 31, 2015, $71,968,000 (US$52,000,000) of the revolving credit facility was payable in US funds and $25,000,000 was payable in Canadian funds. At December 31, 2016, $156,693,000 (US$116,700,000) (2015  nil) of the
term loan was payable in US funds and $300,000,000 (2015  nil) was payable in Canadian funds. The average interest rate applicable at December 31, 2016, for the New Credit Facilities was 3.13% (2015  1.72%).

The funds available under the revolving credit facility are reduced by any outstanding letters of credit issued pursuant to the facility agreement. At
December 31, 2016, the Company had issued and outstanding letters of credit that expire at various dates before January 2018, are payable in various currencies, and total $54,729,000 (2015  $919,000). These letters of credit were issued
in the normal course of operations, including the guarantee of certain office rental obligations. At December 31, 2016, $329,141,000 (2015  $252,113,000) was available in the new revolving credit facility for future activities.

At December 31, 2016, there were $3,628,000 (2015  nil) in additional letters of credit issued and outstanding, outside of the Companys
revolving credit facility. These were issued in various currencies and expire at various dates before November 2017.

The Company previously had a bid
bond facility expiring on August 31, 2018, in the amount of $15 million. This facility allowed the Company access to an additional $5 million under the same terms and conditions upon approval from its lenders. It was used for the
issuance of bid bonds, performance guarantees, letters of credit, and documentary credits in foreign currencies. As a result of entering into the agreement for the New Credit Facilities, this facility was cancelled during the quarter ended
June 30, 2016. At December 31, 2015, $10,828,000 was issued under this bid bond facility, which was payable in various currencies and set to expire at various dates before April 2017.

Senior secured notes

The Company previously issued $70 million
of 4.332% senior secured notes due May 10, 2016, and $55 million of 4.757% senior secured notes due May 10, 2018. These amounts were recorded net of transaction costs of $1,115,000. The senior secured notes were issued pursuant to an
indenture dated May 13, 2011, between the Company, as issuer, and BNY Trust Company of Canada, as trustee and collateral agent; they were ranked pari passuwith the Companys existing revolving credit facility; and they contained
restrictive covenants (note 27). Interest on the senior secured notes was payable semi-annually in arrears on May 10 and November 10 until maturity or the earlier of payment, redemption, or purchase in full of the senior secured notes.

The senior secured notes were redeemable by the Company, in whole at any time or in part from time to time, at specified redemption prices and subject to
certain conditions required by the indenture, with an option for the Company to purchase the notes for cancellation at any time. The senior secured notes were redeemed with the proceeds from the New Credit Facilities (described above). The breakage
fee paid on redemption was $3,926,000 and was recorded in net interest expense.

Surety facilities

The Company has surety facilities to facilitate, as part of the normal course of operations, the issuance of bonds for certain types of project work. At
December 31, 2016, the Company issued bonds under these surety facilities

totaling $162,000 (2015  $387,000) in Canadian funds and $430,630,000 (US$320,719,000) (2015  $4,726,000 (US$3,415,000)) in US funds and $1,320,000 in other foreign currencies. These
bonds expire at various dates before November 2020.

Finance lease obligations

The Company has finance leases for software and for automotive and office equipment. At December 31, 2016, finance lease obligations included finance
leases bearing interest at rates ranging from 1.37% to 5.93% (2015  0.66% to 9.08%). These finance leases expire at various dates before November 2021.

Future minimum lease payments under finance leases and the present value of the net minimum lease payments are as follows:

In the normal conduct of operations, various legal claims are pending against the Company, alleging, among other things,
breaches of contract or negligence in connection with the performance of consulting and construction services. The Company carries professional liability insurance, subject to certain deductibles and policy limits, and has a captive insurance
company that provides insurance protection against such claims. In some cases, the Company may be subject to claims for which it is only partly insured or completely insured. Damages assessed in connection with, and the cost of defending, such
actions could be substantial and possibly in excess of policy limits, for which a range of possible outcomes are either not able to be estimated or not expected to be significant. However, based on advice and information provided by legal counsel,
the Companys previous experience with the settlement of similar claims, and the results of the annual actuarial review, management believes that the Company has recognized adequate provisions for probable and reasonably estimated liabilities
associated with these claims. In addition, management believes that it has appropriate insurance in place to respond to and offset the cost of resolving these claims.

Due to uncertainties in the nature of the Companys legal claims, such as the range of possible outcomes and the progress of the litigation, provisions
accrued involve estimates. The ultimate cost to resolve these claims may exceed or be less than that recorded in the consolidated financial statements. Management believes that the ultimate cost to resolve these claims will not materially exceed the
insurance coverage or provisions accrued and, therefore, would not have a material adverse effect on the Companys consolidated statements of income and financial position.

Management regularly reviews the timing of the outflows of these provisions. Cash outflows for existing
provisions are expected to occur within the next one to five years, although this is uncertain and depends on the development of the various claims. These outflows are not expected to have a material impact on the Companys cash flows.

19. NET EMPLOYEE DEFINED BENEFIT LIABILITY

Resulting from the MWH acquisition on May 6, 2016, the Company became the sponsor of defined benefit pension plans (the Plans) covering certain full-time
employees and past employees, primarily in the United Kingdom. The benefits for the defined benefit pension plans are based on final compensation and years of service. The Plans ceased all future service benefits, although the future salary link has
been retained for certain continuing active members.

The Plans are governed by the laws of the United Kingdom. Each pension plan has a board of trustees,
consisting of four employer-appointed trustees (of which one is a professional trustee) and two-member nominated trustees, that is responsible for administering the plan assets and defining the Plans
investment policies.

The funding objective of each pension plan is to have sufficient and appropriate assets to meet actuarial liabilities. The board of
trustees reviews the level of funding required based on separate triennial actuarial valuations for funding purposes; the most recent was completed as at March 31, 2014. The Plans require that contributions be made to separately administered
funds, which are maintained independently with custodians. The Company expects to contribute $11,800,000 to the Plans in 2017.

The Plans expose the
Company to a number of risks, including: changes to long-term UK interest rates and inflation expectations, movements in global investment markets, changes in life expectancy rates, foreign exchange risk, and regulatory risk from changes in UK
pension legislation. As the plan assets include significant investments in equities, the Company is also exposed to price risk.

Guaranteed annuities are
purchased for certain plan members upon retirement which protects a portion of the Plans from changes in interest rates and longevity post retirement. Post-retirement benefits that are fully matched with insurance policies have been included in both
the asset and liability figures in the following tables.

A program of liability-driven investments (LDIs) has been implemented to hedge a portion of the
Plans long-term interest rate risk. The LDI program is at a relatively early stage and relates to only a portion of the Plans investments; therefore, the Plans remain exposed to significant interest rate risk, along with the other risks
mentioned above.



|                                                                 |  |      |  |

The investment policy for the Plans is to balance risk and return. Approximately 40% of the Plans assets are invested in
mutual funds and exchange-traded funds (both of which are fair valued using quoted market prices) or held in cash. Approximately 30% of the Plans assets are held in annuity policies which are purchased for certain plan members upon retirement.
The fair value of these policies reflects the value of the obligation for these retired plan members determined using actuarial techniques and guaranteed annuity rates. The remaining assets of the Plans are invested in a wholly insured with-profits
insurance contract with a major insurance company. Contributions made to this contract are invested in insurance policies administered by third parties, which provide for a declared rate of interest. The yields on the investments are intended to
provide for a steady return on the assets, which is not wholly dependent on stock market fluctuations, to reflect the long-term performance of the investment. The insurance contract is fair valued using valuation techniques with market observable
inputs.

The present value of the defined benefit obligation is determined by discounting the estimated future cash flows using actuarial valuations. The
principal assumptions used in determining pension benefit obligations for the Plans are shown below (expressed as weighted averages):

The sensitivity analyses above have been determined based on a method that extrapolates the impact on the defined benefit
obligation as a result of reasonable changes in key assumptions occurring at the end of the reporting period. The sensitivity analyses are based on a change in a significant assumption, keeping all other assumptions constant, and may not be
representative of an actual change in the defined benefit obligation as it is unlikely that changes in assumptions would occur in isolation of one another.

21. DERIVATIVE FINANCIAL INSTRUMENTS

During the year ended December 31, 2016, the Company entered into US$773 million foreign currency forward contract agreements to purchase
US$773 million for $1,009 million at fixed rates varying from 1.3236 to 1.28655 that matured on May 6, 2016. These derivative financial instruments were entered into to mitigate foreign currency fluctuation risk on the purchase price
of MWH that was to be paid in US dollars. The fair value of the contracts resulted in a realized loss of $10,244,000. The Company designated these foreign currency forward contracts as a cash flow hedge against the purchase price of MWH; therefore,
the unrealized loss relating to these derivative financial instruments was recorded in other comprehensive income until it was realized on the maturity date. The hedging relationship was effective to the date of maturity.

22. COMMITMENTS

The Company has various operating lease
commitments, including commitments for annual basic premises rent under long-term leases and equipment and vehicle operating leases. The Company also has purchase obligations for cloud services, software support, and equipment. Depending on the
agreement, the Company may enter into renewal options or escalation clauses.

23. CONTINGENCIES AND GUARANTEES

The nature of the Companys
legal claims and the provisions recorded for these claims are described in note 18. Although the Company accrues adequate provisions for probable legal claims, it has contingent liabilities relating to reported legal incidents that, based on current
known facts, are not probable to result in future cash outflows. The Company is monitoring these incidents and will accrue no provision until further information results in a situation in which the criteria required to record a provision is met. Due
to the nature of these incidents, such as the range of possible outcomes and the possibility of litigation, it is not practicable for management to estimate the financial effects of these incidents, the amount and timing of future outflows, and the
possibility of any reimbursement of these outflows.

In the normal course of business, the Company provides indemnifications and, in limited
circumstances, surety bonds and guarantees. These are often standard contractual terms and are provided to counterparties in transactions such as purchase and sale contracts for assets or shares, service agreements, and leasing transactions. The
Company also indemnifies its directors and officers against any and all claims or losses reasonably incurred in the performance of their service to the Company to the extent permitted by law. These indemnifications may require the Company to
compensate the counterparty for costs incurred as a result of various events, including changes to or in the interpretation of laws and regulations, or as a result of damages or statutory sanctions that may be suffered by the counterparty as a
consequence of the transaction. The terms of these indemnifications and guarantees will vary based on the contract, the nature of which prevents the Company from making a reasonable estimate of the maximum potential amount that it could be required
to pay to counterparties. In most cases, the potential payment amount of an outstanding indemnification or guarantee is limited to the remaining cost of work to be performed under engineering and construction contracts. The Company carries liability
insurance, subject to certain deductibles and policy limits, that provides protection against certain insurable indemnifications. Historically, the Company has not made any material payments under such indemnifications or guarantees, and no amounts
have been accrued in the consolidated financial statements with respect to these indemnifications and guarantees.

Common shares

During 2015, the
Company filed a Normal Course Issuer Bid with the TSX, which enabled it to purchase up to 3,774,179 common shares during the period of November 10, 2015, to November 9, 2016. During 2016, 572,825 common shares were repurchased for
cancellation pursuant to the ongoing Normal Course Issuer Bid at a cost of $18,210,000. Of this amount, $1,754,000 and $95,000 reduced the share capital and contributed surplus accounts, respectively, with $16,361,000 being charged to retained
earnings. On November 9, 2016, the Company received approval from the TSX respecting the renewal of the Companys Normal Course Issuer Bid which enables it to purchase up to 3,418,357 common shares during the period November 14, 2016,
to November 13, 2017. No common shares were repurchased for cancellation in 2015.

During 2016, the Company filed a short-form prospectus with
securities regulators in Canada and the United States to allow for the issuance of 17,360,000 in subscription receipts for $525,140,000, representing the right of the holder to

receive, without payment of additional consideration, one common share of the Company upon closing of the MWH
acquisition. After share issuance costs of $22,781,000, the net proceeds to the Company were $502,359,000. The underwriters exercised their option to purchase an overallotment of 2,604,000 subscription receipts for $78,771,000 under the same terms
as above. After share issuance costs of $3,069,000, the net proceeds on the overallotment were $75,702,000. Therefore, the total price to the public, the issuance costs, and the net proceeds to the Company were $603,911,000, $25,850,000, and
$578,061,000, respectively.

During 2016, the Company recognized a share-based compensation expense of $8,912,000 (2015  $11,200,000) in
administrative and marketing expenses in the consolidated statements of income. Of the amount expensed, $4,418,000 (2015  $5,238,000) related to the fair value of options granted and $4,494,000 (2015  $5,962,000) related to the
cash-settled share-based compensation (DSUs, RSUs, and PSUs).

The fair value of options granted was reflected through contributed surplus, and the
cash-settled share-based compensation was reflected through other liabilities. Upon the exercise of share options, for which a share-based compensation expense has been recognized, the cash paid, together with the related portion of contributed
surplus, is credited to share capital.

Holders of
common shares are entitled to receive dividends when declared by the Companys board of directors.

The fair value of options granted is determined at the date of grant using the Black-Scholes option-pricing model. The model
was developed to use when estimating the fair value of traded options that have no vesting restrictions and are fully transferable. Option valuation models require the input of highly subjective assumptions.

In 2016, the Company granted 995,904 (2015  965,064) share options. The estimated fair value of options granted at the share market price on the grant
date was $5.22 (2015  $5.86) and was determined using the weighted average assumptions indicated below:



|                                                    |  |       |  |

|Risk-free interest rate (%)                         |  | 0.76  |  | 0.59 
|Expected hold period to exercise (years)            |  | 3.50  |  | 4.50

|Exercise price ($)                                  |  | 32.83 |  | 32.01

The expected volatility was based on the historical volatility of the Companys shares over a period commensurate with
the expected hold period of the share options. The risk-free interest rate for the expected hold period of the options was based on the yield available on government bonds, with an approximate equivalent remaining term at the time of the grant.
Historical data was used to estimate the expected hold period before exercising the options. The options have a contractual life of five years.

A summary
of the status of the Companys non-vested options as at December 31, 2016, and of changes in the period are as follows:

As at December 31, 2016, 1,826,629 (2015  1,722,237) options remained unvested. As at December 31, 2016, a
total compensation cost of $3,938,000 (2015  $3,501,000) relating to the Companys share option plans remained unrecognized. This cost is expected to be recognized over a weighted average period of 0.98 years (2015  0.86 years).

Under the Companys restricted share unit (RSU) plan, senior vice presidents (SVPs) received RSUs. An RSU is equal to one common share. After two years
from the date granted, SVPs received a cash payment equivalent to the weighted-by-volume average of the closing price of the Companys common shares for the last 10
trading days before the units release date. The RSUs vested on their grant date since the SVPs were not required to complete a specified period of service. The units were recorded at fair value. RSUs were adjusted for dividends as they arose,
based on the number of units outstanding on the record date.

During 2016, no RSUs (2015  494) were issued and 38,450 RSUs were paid at an
intrinsic value of $1,137,000 (2015  50,535 units paid at an intrinsic value of $1,647,000). At December 31, 2016, no RSUs were outstanding (2015  38,450 RSUs were outstanding at a fair value of $1,135,000).

c) Performance share units

Under the Companys Long-Term
Incentive Plan, certain members of the senior leadership teams, including the chief executive officer (CEO), may be granted performance share units (PSUs). These units are adjusted for dividends as they arise, based on the number of units held on
the record date. PSUs vest upon completing a three-year service condition that starts on the grant date. The number of units that vest is subject to a percentage that can range from 0% to 200%, depending on achieving two equally weighted three-year
performance objectives based on net income growth and return on equity. For units that vest, unit holders receive a cash payment based on the closing price of the Companys common shares on the third anniversary date of issue. The fair value of
these units is expensed over their three-year vesting period.

During 2016, 233,255 PSUs were issued (2015  197,370) and 5,243 units were forfeited
(2015  5,064). At December 31, 2016, 576,055 PSUs were outstanding at a fair value of $15,452,000 (2015  348,043 PSUs were outstanding at a fair value of $9,962,000).

d) Deferred share units

The Company also has a deferred share unit
(DSU) plan; directors of the board may receive DSUs. A DSU is equal to one common share. Before 2014, the CEO could also receive DSUs. These units vest on their grant date and are paid in cash to the CEO and directors of the board on their death or
retirement, or in the case of the CEO, in cash on termination. They are valued at the weighted-by-volume average of the closing market price of the Companys common
shares for the last 10 trading days of the month of death, retirement, or termination. These units are recorded at fair value. DSUs are adjusted for dividends as they arise, based on the number of units outstanding on the record date.

During 2016, 37,325 DSUs (2015  57,073) were issued. At December 31, 2016, 466,365 DSUs were outstanding at the fair value of $16,150,000 (2015
 476,777 DSUs were outstanding at a fair value of $16,550,000).

25. FAIR VALUE MEASUREMENTS

All financial instruments carried at fair value are categorized into one of the following three categories:



| |  |  | Level 1  quoted market prices in active markets for identical assets or liabilities at the measurement date
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | Level 2  observable inputs other than quoted prices included within level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical assets or liabilities that
are not active, or other inputs that are observable directly or indirectly
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3  unobservable inputs for the assets and liabilities that reflect the reporting entitys own assumptions and are not based on observable market data
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------

When forming estimates, the Company uses the most observable inputs available for valuation purposes. If a fair value measurement reflects inputs of different
levels within the hierarchy, the financial instrument is categorized based on the lowest level of significant input.



|                                                                 |  |      |  |

---

When determining fair value, the Company considers the principal or most advantageous market in which it would
transact and the assumptions that market participants would use when pricing the asset or liability. The Company measures certain financial assets at fair value on a recurring basis. During 2016, no change was made to the method of determining fair
value.

For financial instruments recognized at fair value on a recurring basis, the Company determines whether transfers have occurred between levels in
the hierarchy by reassessing categorizations at the end of each reporting period. During the year ended December 31, 2016, no transfers were made between levels 1 and 2 fair value measurements.

The following table summarizes the Companys fair value hierarchy for those assets and liabilities measured and adjusted to fair value on a recurring
basis as at December 31, 2016:



|                                              |  |       |    |  |                 |  |         |                                                          |  |  |                                             |  |  |                                           |         |  |  |  |   |

Investments held for self-insured liabilities consist of government and corporate bonds, equity securities, and term deposits.
Fair value of equities is determined using the reported net asset value per share of the investment funds. The funds derive their value from the observable quoted prices of the equities owned that are traded in an active market. Fair value of bonds
is determined using observable prices of debt with characteristics and maturities that are similar to the bonds being valued.

The following table
summarizes the Companys fair value hierarchy for those liabilities that were not measured at fair value but are required to be disclosed at fair value on a recurring basis as at December 31, 2016:



|                                   |  |      |    |  |                                |  |         |                                                          |  |  |                                             |  |  |                                           |         |  |  |  |   |

The fair values of notes payable are determined by calculating the present value of future payments using observable benchmark
interest rates and credit spreads for debt with similar characteristics and maturities.

26. FINANCIAL INSTRUMENTS

Credit risk

Credit risk is the risk of financial loss to the
Company if a counterparty to a financial instrument fails to meet its contractual obligation. Financial instruments that subject the Company to credit risk consist primarily of cash and cash equivalents, cash in escrow, trade and other receivables,
investments held for self-insured liabilities, holdbacks on long-term contracts, and indemnifications.



|                                                                 |  |      |  |             
|---------------------------------------------------------------- |  | ---- |  | ------------
|Notes to the Consolidated Financial Statements
December 31, 2016 |  | F-47 |  | Stantec Inc.



---

The Companys maximum amount of credit risk exposure is limited to the carrying amount of these financial
instruments, which, at December 31, 2016, was $1,203,532,000 (2015  $785,795,000).

The Company limits its exposure to credit risk by placing
its cash and cash equivalents in and entering into derivative agreements with high-quality credit institutions. Investments held for self-insured liabilities include corporate bonds, equities, and term deposits. The risk associated with corporate
bonds, equities, and term deposits is mitigated by the overall quality and mix of the Companys investment portfolio.

The Company mitigates the risk
associated with trade and other receivables and holdbacks on long-term contracts by providing services to diverse clients in various industries and sectors of the economy. The Company does not concentrate its credit risk in any particular client,
industry, or economic or geographic sector. In addition, management reviews trade and other receivables past due on an ongoing basis to identify matters that could potentially delay the collection of funds at an early stage. The Company monitors
trade receivables to an internal target of days of revenue in trade receivables, which, at December 31, 2016, was 57 days (2015  68 days).

Liquidity
risk

Liquidity risk is the risk that the Company will not be able to meet obligations associated with its financial liabilities as they fall due. The
Company meets its liquidity needs through a variety of sources, including cash generated from operations, long- and short-term borrowings from its $800 million revolving credit facility and term loan, and the issuance of common shares. The
unused capacity of the revolving credit facility at December 31, 2016, was $329,141,000 (2015  $252,113,000). The Company believes that it has sufficient resources to meet its obligations associated with its financial liabilities.
Liquidity risk is managed according to the Companys internal guideline of maintaining a net debt to EBITDA ratio of less than 2.5 (note 7).

The
timing of undiscounted cash outflows relating to financial liabilities is outlined in the table below:



|                                   |  |           |  |                  |  |              |  |

In addition to the financial liabilities listed in the table, the Company will pay interest on the revolving credit facility

and term loan outstanding in future periods. Further information on long-term debt is included in note 17.

Interest rate risk

Interest rate risk is the risk that the fair
value of the future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Company is subject to interest rate cash flow risk to the extent that its revolving credit facility and term loan are based on
floating interest rates. The Company is also subject to interest rate pricing risk to the extent that its investments held for self-insured liabilities include fixed-rate government and corporate bonds and term deposits.

If the interest rate on the Companys revolving credit facility and term loan balances at December 31, 2016, was 0.5% higher, with all other
variables held constant, net income would have decreased by $2,390,000. If it was 0.5% lower, an equal and opposite impact on net income would have occurred.



|                                                                 |  |      |  |

---

Foreign exchange risk

Foreign exchange risk is the risk that the fair value of the future cash flows of a financial instrument will fluctuate because of changes in foreign exchange
rates. Foreign exchange gains or losses in net income arise on the translation of foreign currencydenominated assets and liabilities (such as trade and other receivables, trade and other payables, and long-term debt) held in the Companys
Canadian operations and foreign subsidiaries. The Company minimizes its exposure to foreign exchange fluctuations on these items by matching foreign currency assets with foreign currency liabilities and, when appropriate, by entering into forward
contracts.

If exchange rates were 1.0% lower at December 31, 2016, with all other variables held constant, net income would have decreased by
$129,000. If they were 1.0% higher, an equal and opposite impact on net income would have occurred.

Foreign exchange fluctuations may also arise on the
translation of the Companys US-based subsidiaries or other foreign subsidiaries, where the functional currency is different from the Canadian dollar, and are recorded in other comprehensive income. The
Company does not hedge for this foreign exchange risk.

Price risk

The Companys investments held for self-insured liabilities are exposed to price risk arising from changes in the market values of the equity funds. This
risk is mitigated because the portfolio of equity funds is monitored regularly and is appropriately diversified. A 1.0% increase in equity prices at December 31, 2016, would have increased the Companys comprehensive income by $337,000. A
1.0% decrease would have had an equal and opposite impact on comprehensive income.

27. CAPITAL MANAGEMENT

The Companys objective when managing capital is to provide sufficient capacity to cover normal operating and capital expenditures, acquisition growth,
and payment of dividends, while maintaining an adequate return for shareholders. The Company defines its capital as the aggregate of long-term debt (including the current portion) and shareholders equity.

The Company manages its capital structure to maintain the flexibility to adjust to changes in economic conditions and acquisition growth and to respond to
interest rate, foreign exchange, credit, and other risks. To maintain or adjust its capital structure, the Company may purchase shares for cancellation pursuant to Normal Course Issuer Bids, issue new shares, or raise or retire debt.

The Company periodically monitors capital by maintaining the following ratio targets:

| |  |  | Net debt to EBITDA ratio below 2.5
| | - |  | ----------------------------------

| |  |  | Return on equity (ROE) at or above 12%
| | - |  | --------------------------------------

These targets are established annually and monitored quarterly. The
Company revised its target for ROE from at or above 14% that was set for 2015 to at or above 12% for 2016. ROE is impacted by net income and by fluctuations in the Canadian dollar since the resulting unrealized gains or losses on the translation of
the Companys foreign subsidiaries impacts shareholders equity. As well, ROE is impacted by remeasurements of the Companys defined benefit pension plans.

Net debt to EBITDA ratio, a non-IFRS measure, is calculated as the sum of (1) long-term debt, including current
portion, plus bank indebtedness, less cash and cash equivalents and cash in escrow, divided by (2) EBITDA, calculated as income before income taxes, net interest expense, amortization of intangible assets, depreciation of property and
equipment, and goodwill and intangible asset impairment. The Companys net debt to EBITDA ratio at December 31, 2016, was 2.38 (2015  0.94), calculated on a trailing four-quarter basis. Going forward, there may be occasions when the
Company exceeds its target by completing acquisitions that increase its debt level above the target for a period of time.

ROE, a non-IFRS measure, is calculated as net income for the last four quarters, divided by average shareholders equity over each of those quarters. The Companys ROE for the year ended December 31, 2016,
was 7.8%



|                                                                 |  |      |  |             
|---------------------------------------------------------------- |  | ---- |  | ------------
|Notes to the Consolidated Financial Statements
December 31, 2016 |  | F-49 |  | Stantec Inc.



---

(2015  12.9%). The Company did not meet its ROE target since net income was impacted by acquisition-related costs and additional shares issued that primarily related to the MWH acquisition.

The Company is subject to restrictive covenants related to its New Credit Facilities that are measured quarterly. These covenants include, but are not
limited to, a leverage ratio and an interest coverage ratio (non-IFRS measures). The leverage ratio is calculated as consolidated debt to EBITDA, and the interest coverage ratio is calculated as EBITDA to
interest expense. Failure to meet the terms of one or more of these covenants may constitute a default, potentially resulting in accelerating the repayment of the debt obligation.

The Company was also subject to restrictive covenants related to its $350 million revolving credit facility and its senior secured notes that were
measured quarterly. These facilities were repaid and redeemed, respectively, during the second quarter of 2016. These covenants included, but were not limited to, consolidated debt to EBITDA and EBITDAR to consolidated debt service ratio (non-IFRS measures). EBITDAR was calculated as EBITDA, plus building rental obligations net of common area costs, taxes, charges, and levies. Failure to meet the terms of one or more of these covenants may have
constituted a default, potentially resulting in accelerating the repayment of the debt obligation.

The Company was in compliance with the covenants under
these agreements as at and throughout the year ended December 31, 2016.

28. INCOME TAXES

The effective income tax rate in the consolidated statements of income differs from statutory Canadian tax rates as a result of the following:

|                                                  |  |                                |  |       |  |  |  |

engineering, planning, and project management. These entities have been designed so that voting rights are not the dominant factor in deciding who controls the entity. Each entity has a management agreement in place that provides the Company with
control over the relevant activities of the entity where it has been assessed that the Company is exposed to variable returns of the entity and can use its power to influence the variable returns. The Company receives a management fee generally
equal to the net income of the entities and has an obligation regarding the liabilities and losses of the entities. Based on these facts and circumstances, management determined that the Company controls these entities, and they are consolidated in
the Companys consolidated financial statements. The Company does not have any unconsolidated structured entities.

The following is a list of
structured entities that are consolidated in the Companys financial statements.

assessing performance. The chief operating decision maker is the CEO of the Company, and the Companys operating segments are based on its two primary service offerings and regional geographic areas.

In 2015 and the first quarter of 2016, the Company had three operating segments: Canada, the United States, and International. These operating segments were
aggregated into one reportable segment: Consulting Services. Effective the second quarter of 2016, in connection with the MWH acquisition, the Company has four reportable segments: Construction Services and Consulting Services by
geographyCanada, the United States, and Global. No operating

segments are aggregated to form the reportable segments. Comparative information was restated to conform to this presentation.

The three Consulting Services reportable segments provide professional consulting in engineering, architecture, interior design, landscape architecture,
surveying, environmental sciences, project management, and project economics services in the area of infrastructure and facilities. The Construction Services reportable segment provides construction management
at-risk services primarily on water-related projects.

Segment performance is evaluated by the CEO based on gross
margin and is measured consistently with gross margin in the consolidated financial statements. Transfer prices between reportable segments are on an arms-length basis in a manner similar to transactions
with third parties. Inter-segment revenues are eliminated on consolidation and reflected in the adjustments and eliminations column.
