Exhibit 99.1 - Stantec Inc.’s Management's Discussion and Analysis

Management’s Discussion and Analysis

August 10, 2022

This discussion and analysis of Stantec Inc.’s (Stantec or the Company) operations, financial position, and cash flows for the quarter and the two quarters ended June 30, 2022, dated August 10, 2022, should be read in conjunction with the Company’s unaudited interim condensed consolidated financial statements and related notes for the quarter and the two quarters ended June 30, 2022, and the Management’s Discussion and Analysis (MD&A) and audited consolidated financial statements and related notes included in our 2021 Annual Report filed on February 23, 2022.

Our unaudited interim consolidated financial statements and related notes for the quarter and the two quarters ended June 30, 2022, are prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). We continue to apply the same accounting policies as those used in 2021. Amendments to accounting standards adopted in the quarter and disclosed in note 3 of our unaudited interim consolidated financial statements for the quarter ended June 30, 2022 (incorporated here by reference), did not have a material impact on the Company's consolidated financial statements or accounting policies. All amounts shown in this report are in Canadian dollars unless otherwise indicated.

Additional information regarding our Company, including our Annual Information Form, is available on SEDAR at sedar.com and on EDGAR at sec.gov. Such additional information is not incorporated here by reference, unless otherwise specified, and should not be deemed to be part of this MD&A. Stantec trades on the TSX and the NYSE under the symbol STN. Visit us at stantec.com or find us on social media.

Non-IFRS and Other Financial Measures

The Company reports its financial results in accordance with IFRS. However, certain indicators used by the Company to analyze and evaluate its results are non-IFRS or other financial measures, including: adjusted EBITDA, adjusted net income, adjusted earnings per share (EPS), adjusted return on invested capital (ROIC), net debt to adjusted EBITDA, days sales outstanding (DSO), free cash flow, margin (percentage of net revenue), organic growth (retraction), acquisition growth, measures described as on a constant currency basis and the impact of foreign exchange or currency fluctuations, compound annual growth rate (CAGR), total capital managed, working capital, and current ratio, as well as measures and ratios calculated using these non-IFRS or other financial measures. These measures are described in the Definitions of Non-IFRS and Other Financial Measures (“Definitions”) and Liquidity and Capital Resources sections of this MD&A and, where applicable, reconciliations from the non-IFRS measure to the most directly comparable measure calculated in accordance with IFRS are provided (see the Financial Highlights, Financial Performance, Liquidity and Capital Resources, and Definitions sections).

These non-IFRS and other financial measures do not have a standardized meaning under IFRS and, therefore, may not be comparable to similar measures presented by other issuers. Management believes that, in addition to conventional measures prepared in accordance with IFRS, these non-IFRS and other financial measures provide useful information to investors to assist them in understanding components of our financial results. These measures should not be considered in isolation or viewed as a substitute for the related financial information prepared in accordance with IFRS.

Business Update

COVID-19 Pandemic

We continue to monitor regional public health guidelines as we transition out of the crisis phase of the pandemic. We remain strongly positioned to capture opportunities arising from infrastructure and stimulus spending, particularly opportunities related to sustainability and resilience. Stantec offices across the globe are open following local re-entry plans and protocols, and our people are attending our offices either full- or part-time according to our flexible work model.

War in Ukraine

Stantec has no offices, employees, or project work in Ukraine, Russia, or Belarus. Therefore, we do not expect the current conflict or economic sanctions will directly affect operations. Management is monitoring the situation for potential impacts and remains diligent in ensuring we are not working with any sanctioned entities or individuals. We have also added the Ukraine conflict to our Risk Factors (see page M-24).

Looking Ahead

As an industry leader in sustainable engineering and through synergies gained with our acquisitions, we are well positioned to address the pipeline of opportunities arising from various stimulus programs, market momentum, and growing demands for sustainable and climate change solutions. Integration activity has also been high, and we remain on schedule to complete the integration of Cardno and several other recently acquired firms.

Q2 2022 compared to Q2 2021

We achieved adjusted diluted EPS of $0.83 in Q2 2022, a $0.21 per share or 33.9% increase from $0.62 in Q2 2021, reflecting strong net revenue growth, solid execution of our strategic growth initiatives, and focused project execution.

•Net revenue increased 22.9% or $208.4 million to $1.1 billion compared to Q2 2021, driven by 9.4% organic growth and 12.4% acquisition growth. Consistent with the first quarter of this year, every one of our regional and business operating units delivered organic growth, most notably in Global and in Water and Environmental Services where organic growth was in the double-digits.

•Project margin increased $119.4 million or 24.7% to $602.7 million as a result of net revenue growth and solid project execution. As a percentage of net revenue, we delivered a 54.0% project margin, an 80 basis point increase from Q2 2021.

•Adjusted EBITDA increased $40.1 million or 27.4% to $186.7 million and achieved a margin of 16.7% compared to 16.1% in the prior period, resulting from strong performance across the business.

•Net income decreased 4.0%, or $2.5 million, to $60.7 million, and diluted EPS decreased 3.5%, or $0.02, to $0.55. Acquisition-related expenses (namely integration, depreciation and amortization, and interest

Management’s Discussion and Analysis June 30, 2022 M-4 Stantec Inc.

expenses), coupled with a net unrealized fair value loss associated with our equity investments held for self-insured liabilities, more than offset increased project margin and lower income tax expense.

•Adjusted net income grew 33.0%, or $23.0 million, to $92.6 million, achieving 8.3% of net revenue compared to 7.7% in Q2 2021, and adjusted diluted EPS increased 33.9% to $0.83 from $0.62 in Q2 2021.

•Contract backlog stands at $5.8 billion at June 30, 2022, a new record reflecting 13.0% organic growth from December 31, 2021. Like net revenue, organic backlog growth was achieved across all our regional and business operating units. Our US operations led with 14.8% organic backlog growth. Global's backlog exceeded $1 billion, a high-water mark, reflecting 13.4% organic growth. Infrastructure, Buildings, and Energy & Resources achieved double-digit organic backlog growth. Contract backlog represents approximately 14 months of work—an increase of one month from December 31, 2021.

•Operating cash flows amounted to an outflow of $4.4 million compared to an inflow of $78.2 million in the prior period reflecting the expected disruptions from the Cardno integration, particularly the financial system migration. Cash outflow was also driven by the increased investment in net working capital to support organic revenue growth and an increase in days sales outstanding (DSO).

•DSO was 79 days, remaining within our expectations, and represents an increase of 4 days from 75 days at December 31, 2021.

•Net debt to adjusted EBITDA (on a trailing twelve-month basis) at June 30, 2022 was 2.0x, remaining within our internal target range of 1.0x to 2.0x.

•In Q2 2022, we repurchased 625,019 common shares at a cost of $36.7 million under our normal course issuer bid (NCIB).

•On April 1, 2022, we acquired Barton Willmore, the UK's leading planning and design consultancy firm. This acquisition added approximately 300 team members across the UK providing services for both public and private clients across all development sectors, which strategically complements our existing business in Infrastructure.

•On August 10, 2022, our Board of Directors declared a dividend of $0.18 per share, payable on October 17, 2022, to shareholders of record on September 29, 2022.

Year-to-date Q2 2022 compared to year-to-date Q2 2021

•Net revenue increased 21.3% or $379.8 million to $2.2 billion compared to 2021 year to date, driven by 7.9% organic growth and 13.2% acquisition growth. All of our regional and business operating units delivered organic growth, most notably in Global and in Environmental Services and Water.

•Project margin increased $220.1 million to $1.2 billion as a result of net revenue growth and solid project execution. As a percentage of net revenue, we delivered 54.0% project margin, a 90 basis point increase.

•Adjusted EBITDA increased $63.2 million or 22.9% to $338.9 million and achieved a margin of 15.6% compared to 15.4% in the prior period, resulting from strong performance across the business.

•Net income decreased 7.5%, or $8.6 million, to $105.5 million, and diluted EPS decreased by 6.9% or $0.07, to $0.95. Acquisition-related expenses (namely integration, depreciation and amortization, and interest expenses), coupled with a net unrealized fair value loss associated with our equity investments held for self-insured liabilities, more than offset increased project margin and lower income tax expense.

Management’s Discussion and Analysis June 30, 2022 M-5 Stantec Inc.

•Adjusted net income grew 28.1%, or $35.3 million, to $161.0 million, achieving 7.4% of net revenue from 7.0%, and adjusted diluted EPS increased 29.5%, or $0.33, to $1.45.

•Operating cash flows amounted to net inflows of $1.6 million compared to $133.9 million in the prior period reflecting the expected disruptions from the Cardno integration, particularly the financial system migration. Cash flow was also lower due to the increased investment in net working capital to support organic revenue growth and due to an increase in DSO.

•Year-to-date Q2 2022, we repurchased 1,085,676 of our common shares under our NCIB program at a cost of $65.3 million.

Financial Targets

We provided our annual targets for 2022 on page M-11 in our 2021 Annual Report (incorporated here by reference). Our year-to-date progress toward these targets in Q2 2022 is as follows:

	2022 Annual Range	Results for the two quarters ended June 30, 2022
Targets
Net revenue growth	18% to 22%	21.3%
Adjusted EBITDA as % of net revenue (note)	15.3% to 16.3%	15.6%
Adjusted net income as % of net revenue (note)	At or above 7.5%	7.4%
Adjusted ROIC (note)	Above 10.5%	(note)

In setting our targets and guidance, the average value for the US dollar is assumed to be $1.25 and for the GBP to be $1.73 (see Assumptions included on page M-26).

note: Adjusted EBITDA, adjusted net income, and adjusted ROIC are non-IFRS measures discussed in the Definitions section of this MD&A. Adjusted ROIC is calculated annually at the end of the year.

Outlook

We reaffirm our guidance provided in the Outlook section of our 2021 Annual Report (incorporated here by reference). Our annual targets and guidance were based on our diversified business, our position as an industry leader to support the growing demands for sustainable solutions, record high backlog, and our continued integration efforts and synergies achieved from acquisitions completed.

We expect net revenue growth between 18% to 22% and that organic net revenue growth will be in the mid to high-single digits, supported by momentum from record-high US backlog and project opportunities arising from the US infrastructure stimulus bill, continued robust activities in Canada, and strong economic growth from continued demand and stimulus in infrastructure sectors in Global. Increased inflation in many geographies has not slowed project opportunities, as the urgency for addressing aging infrastructure, climate risk resiliency, healthcare, and onshoring for supply chain security has not abated. Our ability to meet the growing demand for our services is dependent on our highly skilled workforce. While we are seeing increased competition for staff and a higher wage environment in key geographies, we believe we continue to be well positioned to retain and attract new employees on the strength of our reputation and people-centric corporate culture, and mitigate these effects on project margins. We continue to expect to deliver annual adjusted EBITDA margin in the range of 15.3% to 16.3% and adjusted net income to be at or above 7.5% driving to growth in adjusted diluted EPS between 22% to 26%.

Our year-to-date Q2 2022 results are in line with our expectations reflecting a protracted ramp-up of US activities for projects awarded in the second half of 2021 and the fact that the first quarter of the year typically has lower levels of activity. While the fourth quarter also typically has lower levels of activity, we expect to be in the higher end of the ranges in the second half of 2022 as the year progresses and activities increase.

Management’s Discussion and Analysis June 30, 2022 M-8 Stantec Inc.

Financial Performance

The following sections outline specific factors that affected the results of our operations in the second quarter of 2022 and Q2 2022 year to date.

Gross and Net Revenue

While providing professional services, we incur certain direct costs for subconsultants, equipment, and other expenditures that are recoverable directly from our clients. Revenue associated with these direct costs is included in gross revenue. Because these direct costs and associated revenue can vary significantly from contract to contract, changes in gross revenue may not be indicative of our revenue trends. Accordingly, we also report net revenue (which is gross revenue less subconsultant and other direct expenses) and analyze results in relation to net revenue rather than gross revenue.

We generate approximately 75% of our gross revenue in foreign currencies, primarily in US dollars, British pounds (GBP), and Australian (AU) dollars. Fluctuations in these and other currencies had a net $10.1 million positive impact on our net revenue results in Q2 2022 compared to Q2 2021 and a net $3.2 million positive impact year to date in 2022 compared to 2021:

•The US dollar averaged $1.23 in Q2 2021 and $1.28 in Q2 2022—a 4.1% increase. Year to date, the US dollar averaged $1.25 in Q2 2021 and $1.27 in Q2 2022—a 1.6% increase. The strengthening US dollar compared to the Canadian dollar had a positive effect on gross and net revenues.

•The GBP averaged $1.72 in Q2 2021 and $1.60 in Q2 2022—a 7.0% decrease. Year to date, the GBP averaged $1.73 in Q2 2021 and $1.65 in Q2 2022—a 4.6% decrease. The weakening GBP compared to the Canadian dollar had a negative effect on gross and net revenues.

•The AU dollar averaged $0.94 in Q2 2021 and $0.91 in Q2 2022—a 3.2% decrease. Year to date, the AU dollar averaged $0.96 in Q2 2021 and $0.91 in Q2 2022—a 5.2% decrease. The weakening AU dollar compared to the Canadian dollar had a negative effect on gross and net revenues.

Fluctuations in other foreign currencies did not have a material impact on our gross and net revenue.

Revenue earned by acquired companies in the first 12 months following an acquisition is reported as revenue from acquisitions and thereafter as organic revenue.

Comparative figures for gross and net revenue by business operating unit have been reclassified due to a realignment of several business lines and to conform to the presentation adopted for the current year.

Acquisitions in 2021 and strengthening market conditions in all of our geographies and businesses contributed to a 22.9% net revenue increase in Q2 2022 compared to Q2 2021 and a 21.3% increase year to date. Drivers contributing to growth included robust public infrastructure spending and private investment; growing project work related to the re-shoring of domestic production to strengthen local supply chain resilience and security, climate change and sustainability, global food security, and the energy transition. Opportunities have also increased in archeological, permitting, and compliance work, as well as building and designing facilities and communities to meet growing civic, healthcare, residential, and industrial markets.

Management’s Discussion and Analysis June 30, 2022 M-11 Stantec Inc.

Canada

In Canada, we achieved 4.9% organic net revenue growth in the quarter and 5.9% year to date, as both private and public spending remained robust. Environmental Services achieved double-digit growth, capitalizing on high demand for permitting work and continued archeological work to support a midstream energy project. A strong housing market in western Canada and continued recovery efforts associated with the extreme flooding in British Columbia late last year drove growth in Infrastructure. Buildings continued to deliver organic growth on the strength of major public sector projects in healthcare while growing momentum behind the energy transition is spurring growth in Energy & Resources.

United States

Net revenue increased 27.2% in the quarter and 21.9% year to date, reflecting acquisition and organic growth and the positive impact of foreign exchange. Strong performance and improving market conditions contributed to achieving organic growth in each of our business units, particularly in Environmental Services and Water, where we drove double-digit growth in the quarter. In Environmental Services, demand continued to be strong for expertise in environmental assessments, permitting, and ecological work, and expanding opportunities in the remediation sector contributed to strong growth. The ramp up of public sector and industrial projects previously delayed by the pandemic and our work in certain large-scale water-scarcity projects in western US boosted growth in Water. Infrastructure also delivered solid organic growth on the strength of major projects in Transportation and industrial and residential land development activities in Community Development. Buildings continued its post-pandemic recovery, achieving growth from increasing investments in healthcare, civic, industrial, and science and technology sectors.

Global

In our Global operations, we achieved net revenue growth of 39.9% in the quarter and 42.8% year to date, reflecting strong acquisition and organic net revenue growth, partly offset with foreign exchange impacts.

Growth momentum from 2021 continued into 2022 and contributed to organic net revenue growth of 16.7% in the quarter and 15.1% year to date, with strong performances in all our business units. Our industry-leading Water business delivered very strong organic growth across the UK, Australia, and New Zealand, while increased demand drove significant organic growth in Buildings and our Community Development sector. Our Mining sector also continued to deliver strong organic growth, driven by high copper and other metal prices, as well as client diversification, increased field services, and fewer pandemic-related restrictions.        

Backlog

We define “backlog” as the total value of secured work that has not yet been completed where we have an executed contract or a letter of intent that management is reasonably assured will be finalized in a formal contract.

(In millions of Canadian dollars, except percentages)	Jun 30, 2022	Dec 31, 2021	Total Change		Change Due to Foreign Exchange		Change Due to Organic Growth		% of Organic Growth
Canada	1,264.7	1,169.1	95.6		n/a		95.6		8.2	%
United States	3,521.1	3,016.9	504.2		57.9		446.3		14.8	%
Global	1,034.6	948.3	86.3		(41.1)		127.4		13.4	%
Total	5,820.4	5,134.3	686.1		16.8		669.3
Percentage Growth			13.3	%	0.3	%	13.0	%

Our contract backlog at June 30, 2022 of $5.8 billion grew organically 13.0%, or $669.3 million, and represents approximately 14 months of work, an increase of one month from December 31, 2021.

Management’s Discussion and Analysis June 30, 2022 M-12 Stantec Inc.

Increases in our contract backlog in Canada were primarily in Infrastructure and Environmental Services. We continued to strengthen our US backlog with new contract awards contributing to double-digit organic growth, particularly in Buildings, Energy & Resources, and Infrastructure. Global backlog organic growth was primarily driven by Energy & Resources, Buildings, and Infrastructure.

Major Project Awards

Major projects awarded in the quarter reflect our expertise in climate-related solutions and our ability to capitalize on growing public infrastructure spending and private investment in key markets. We also continued to leverage client relationships and expand our work on projects related to domestic manufacturing re-shoring and supply chain resilience.

In Canada, our Water business was successful in winning two significant projects: the Buffalo Pound Water Treatment Plant Renewal Project in Saskatchewan and program management consulting for the Iona Island Wastewater Treatment Plant Projects in Vancouver, Metro Vancouver’s largest capital program ever undertaken. Our Environmental Services team was selected to provide professional services for traffic light, telecommunications infrastructure, and mobility projects in Montreal. Other major wins in the quarter included engineering and architecture design services for a major industrial operations facility and professional services for the Lakehaven community development project, Ontario's first mixed-ownership development to improve housing affordability.

Project award highlights in the United States include a contract with the Nebraska Department of Natural Resources to conduct floodplain modeling and mapping and several major wins in our Water business. These include design services for the next phase of the Boston Water and Sewer Commission's East Boston Sewer Separation project and a multi-year task order awarded by the US Army Corps of Engineers Alaska District to provide architecture and engineering services related to critical civil works involving flood and storm damage protection and watershed studies. We also extended our work on Hawaii's driverless electric light-rail transit project and were selected to lead construction management on the zero-emission Blue Line Bus Rapid Transit project in Indianapolis.

In our Global operations, project award highlights from the second quarter include a significant Mining win in Australia. Our team was awarded a contract to design a new hydrofloat system that will improve plant feed rates at the Carrapateena Copper mine in South Australia. In the UK, we were awarded several multi-disciplinary frameworks to support community development and infrastructure improvement. Also, we were awarded a transportation framework project in western Scotland to support climate change adaptation and decarbonization.

Project Margin

In general, project margin fluctuations depend on the particular mix of projects in progress during any quarter and on project execution. The fluctuations reflect our business model, which is based on providing services across diverse geographic locations, business operating units, and all phases of the infrastructure and facilities project life cycle. For a definition of project margin, refer to the Financial Performance section of our 2021 Annual Report (incorporated here by reference).

Project Margin by Reportable Segment

Total	602.7	54.0	%	483.3	53.2%	1,169.8	54.0	%	949.7	53.1%

Comparative figures for project margin by business operating unit have been reclassified due to a realignment of several business lines and to conform to the presentation adopted for the current year.

In the quarter, project margin increased $119.4 million, or 24.7%, and as a percentage of net revenue, project margin increased 80 basis points to 54.0%. Year to date, project margin increased $220.1 million or 23.2% and as a percentage of net revenue, project margin increased 90 basis points to 54.0%. Net revenue growth driven by the global economic recovery and acquisitions contributed to the project margin increase. Favorable project mix, increased selectivity in project pursuits, and continued discipline in our project execution resulted in higher project margin as a percentage of net revenue.

In Canada, project margin in the quarter increased $5.3 million to $154.6 million and year to date increased $13.8 million to $299.7 million. As a percentage of net revenue, project margin was 53.0% in the quarter and year to date, a 70 and 50 basis point decrease, respectively, compared to the prior periods due primarily to changes in estimates to complete on discrete projects in Environmental Services and Energy & Resources.

Project margin in the US operations increased $74.4 million or 31.5%, and increased 180 basis points to 54.9% as a percentage of net revenue in the quarter. We drove solid project performance across all of our businesses, particularly in Infrastructure and Environmental Services.

In our Global operations, project margin increased $39.7 million to $137.2 million and increased 30 basis points to 52.9% as a percentage of net revenue in the quarter. Margin expansion was driven largely by strengthened project execution in Buildings and in our Community Development sector.

Administrative and Marketing Expenses

Administrative and marketing expenses increased $90.3 million and as a percentage of net revenue were 38.6% in Q2 2022 compared to 37.6% in Q2 2021. Year to date, administrative and marketing expenses increased $174.9 million and as a percentage of net revenue were 39.6% compared to 38.2% in the same period in 2021. The increases were largely attributed to business development efforts on major programs and bids, discretionary spending, integration costs of $6.0 million and $6.8 million respectively, increased provisions for claims estimates, investments in internal resources to support growth and cybersecurity, and higher subscription costs for software solutions that are now cloud-based and expensed as incurred. Partly offsetting these increases was a lower share-based compensation cost of $0.6 million in the quarter and $9.8 million year to date.

Amortization of Intangible Assets

The timing of completed acquisitions, size of acquisitions, and type of intangible assets acquired impact the amount

of amortization of intangible assets in a period. Client relationships are amortized over estimated useful lives ranging from 10 to 15 years and contract backlog are amortized over an estimated useful life of 1 to 3 years. Consequently, the impact of amortization can be significant in the reporting periods following an acquisition.

Management’s Discussion and Analysis June 30, 2022 M-14 Stantec Inc.

	Quarter Ended Jun 30,		Two Quarters Ended Jun 30,
(In millions of Canadian dollars)	2022	2021	2022	2021
Client relationships	11.5	7.8	22.6	15.6
Backlog and other	9.1	1.1	17.0	1.9
Total amortization of acquired intangible assets	20.6	8.9	39.6	17.5
Software	5.6	4.8	10.9	9.5
Total amortization of intangible assets	26.2	13.7	50.5	27.0

Acquisitions completed in 2021 and 2022 added $162.9 million to client relationships and $53.5 million to backlog and contributed to an increase in intangible amortization during the quarter and the first two quarters of 2022 compared to the same periods in the prior year.

Depreciation of Lease Assets

Depreciation of lease assets increased $3.6 million in the quarter and $7.3 million in the first two quarters compared to the same periods in 2021. The increase in depreciation is primarily due to acquisitions made in 2021 which increased lease assets by approximately $80 million.

Net Interest Expense

Net interest expense increased $4.8 million in the quarter and $7.9 million in the first two quarters compared to the same periods in 2021. This was primarily due to higher draws on the revolving credit facility to fund the Cardno, CMEC, and Barton Willmore acquisitions and share repurchases under our NCIB, and higher interest rates on our credit facilities.

Other Income

Other income from our investments held for self-insured liabilities included a net loss of $4.0 million year to date compared to a net gain of $10.4 million in the same period in 2021. In the current period, unrealized losses of $18.5 million were partly offset by realized gains of $14.5 million from the sale of equity securities. Unrealized gains and losses are non-cash adjustments and represent the fair value fluctuations in the equity markets.

Income Taxes

Our effective income tax rate decreased from 23.9% in Q2 2021 to 23.6% in Q2 2022 and year to date from 24.5% in 2021 to 23.7% in 2022 as a result of our continuing tax planning and optimization strategies, and remained consistent with the annual effective tax rate of 23.7% in 2021.

Summary of Quarterly Results

The following table presents selected data derived from our consolidated financial statements for each of the eight most recently completed quarters. This information should be read in conjunction with the applicable interim unaudited and annual audited consolidated financial statements and related notes.

note: Adjusted net income and adjusted EPS are non-IFRS measures further discussed in the Definitions section of this MD&A.

Quarterly EPS and adjusted EPS are not additive and may not equal the annual EPS reported. This is a result of the effect of shares issued on the weighted average number of shares. Quarterly and annual diluted EPS and adjusted EPS are also affected by the change in the market price of our shares since we do not include dilutive options when the exercise price of the option is not in the money.

The table below compares quarters, summarizing the impact of acquisitions, organic growth, and foreign exchange on net revenue:

	Q2 2022	Q1 2022	Q4 2021	Q3 2021
	vs.	vs.	vs.	vs.

Total net increase in net revenue	208.4	171.4	54.5	16.4

We experience variability in our results of operations from quarter to quarter due to the nature of the sectors and geographic locations we operate in. In the first and fourth quarters, we see slowdowns related to winter weather conditions in the northern hemisphere and holiday schedules. The net increase in net revenue from Q2 2022 compared to Q2 2021 primarily reflects acquisition growth from revenues contributed by acquisitions completed in the last twelve months, organic growth, and positive foreign exchange impact. (See additional information on the operating results in our MD&A for each respective quarter.)

Statements of Financial Position

The following table highlights the major changes to assets, liabilities, and equity since December 31, 2021:

(In millions of Canadian dollars)	Jun 30, 2022	Dec 31, 2021
Total current assets	1,840.1	1,664.4
Property and equipment	227.5	233.7

Deferred tax liability	59.1	77.5
Other liabilities	24.9	38.0
Equity	2,007.6	2,001.7
Non-controlling interests	0.4	0.5
Total liabilities and equity	5,318.6	5,226.4

Refer to the Liquidity and Capital Resources section of this MD&A for an explanation of the changes in current assets, current liabilities, and shareholders’ equity.

The carrying amounts of assets and liabilities for our US and other foreign subsidiaries on our consolidated statements of financial position decreased slightly primarily due to the weakening of the British pound and Australian dollar relative to the Canadian dollar, partially offset by the strengthening of the US dollar relative to the Canadian dollar. Other factors that impacted our long-term assets and liabilities are indicated below.

The impact of the Barton Willmore acquisition and measurement period adjustments for prior acquisitions increased intangible assets by $12.8 million and goodwill by $48.6 million. These values are based on a preliminary purchase price allocation and are pending a final determination of the fair value of the assets and liabilities acquired. The final allocation may differ from the preliminary allocation.

Additions of engineering equipment and leasehold improvements in property and equipment, lease additions and modifications, and software additions and acquired assets in intangible assets were offset by depreciation and amortization expense. Total current and long-term portions of other assets decreased mainly as a result of decreases in investments held for self-insured liabilities, including net sales of investments and unrealized fair value losses.

Management’s Discussion and Analysis June 30, 2022 M-17 Stantec Inc.

Total current and long-term portions of long-term debt increased $144.2 million due primarily to an increase in draws on our revolving credit facility, largely used to finance the Barton Willmore acquisition and share repurchases under our NCIB and due to the Cardno integration. Total current and long-term portions of lease liabilities decreased $53.7 million due to lease payments made, partly offset by additions, modifications, and interest accretion.

Net employee defined benefit liability decreased $10.0 million, and net employee defined benefit asset decreased $1.8 million for a combined net decrease in employee benefit obligations of $8.2 million. The decrease was primarily due to contributions made to the defined benefit pension plans.

Total current and long-term portions of other liabilities decreased $20.1 million due primarily to a decrease in liabilities for cash-settled share-based compensation as a result of payments of $23.3 million in the period.

Net deferred taxes decreased $21.9 million, including a reduction in net deferred taxes related to the amortization of previously acquired intangible assets, partly offset by an increase in deferred tax assets related to measurement period adjustments on prior acquisitions.

Liquidity and Capital Resources

We are able to meet our liquidity needs through various sources, including cash generated from operations, long- and short-term borrowings from our $800 million revolving credit facility (with access to an additional $600 million subject to approval), our $310 million senior term loan, proceeds from the $300 million private placement of our senior unsecured notes, and the issuance of common shares. We use funds primarily to pay operational expenses; complete acquisitions; sustain capital spending on property, equipment, and software; repay long-term debt; repurchase shares; and pay dividend distributions to shareholders.

We believe that internally generated cash flows, supplemented by borrowings, if necessary, will be sufficient to cover our normal operating and capital expenditures. However, under certain favorable market conditions, we do consider issuing common shares to facilitate acquisition growth or to reduce borrowings under our credit facilities.

Working Capital

The following table summarizes working capital information at June 30, 2022, compared to December 31, 2021:

(In millions of Canadian dollars, except ratios)	Jun 30, 2022	Dec 31, 2021
Current assets	1,840.1	1,664.4
Current liabilities	1,196.7	1,179.4
Working capital (note)	643.4	485.0
Current ratio (note)	1.54	1.41

Note: Working capital is a non-IFRS measure that does not have a standardized meaning under IFRS and, therefore, may not be comparable to similar measures presented by other issuers. We use working capital as a measure for assessing overall liquidity and it calculated by subtracting current liabilities from current assets. There is no directly comparable IFRS measure for working capital. Current ratio is calculated by dividing current assets by current liabilities.

The carrying amounts of assets and liabilities for our US subsidiaries and other foreign subsidiaries on our consolidated statements of financial position decreased slightly primarily due to the weakening of the British pound and Australian dollar relative to the Canadian dollar, partially offset by the strengthening of the US dollar relative to the Canadian dollar. Other factors that impacted our current assets and liabilities are indicated below.

Management’s Discussion and Analysis June 30, 2022 M-18 Stantec Inc.

Current assets increased primarily because of a collective $190.6 million increase in trade and other receivables, unbilled receivables, and contract assets. This was partly offset by a decrease in cash and deposits of $24.7 million (explained in the Cash Flows section of this MD&A).

•Our DSO, defined in the Definitions section of this MD&A, was 79 days at June 30, 2022, an increase of 4 days from December 31, 2021 and 3 days from June 30, 2021. The increase in DSO is primarily driven by the integration of Cardno, particularly the financial system migration.

•The aging of total trade receivables greater than 30 days remained consistent with December 31, 2021, with slight movements between aging categories.

The increase in current liabilities included an increase in bank indebtedness (explained in the Cash Flows section of this MD&A). Provisions also increased, primarily due to settlements of claims that we are in the process of finalizing or negotiating for which we have third-party insurer coverage and a corresponding insurance recovery recorded in trade and other receivables, and an increase in estimates for claim provisions. These increases were offset by decreases in trade and other payables, other liabilities, and the current portions of lease liabilities and long-term debt (explained in the Statement of Financial Position section of this MD&A).

Cash Flows

Our cash flows from and used in operating, investing, and financing activities are reflected in the consolidated statements of cash flows and are summarized below:

	Quarter Ended Jun 30,			Two Quarters Ended Jun 30,
(In millions of Canadian dollars)	2022	2021	Change	2022	2021	Change
Cash (used in) flows from operating activities	(4.4)	78.2	(82.6)	1.6	133.9	(132.3)
Cash flows used in investing activities	(40.0)	(30.3)	(9.7)	(11.6)	(53.9)	42.3
Cash flows from (used in) financing activities	14.3	(87.4)	101.7	(10.0)	(149.3)	139.3

Cash Flows From Operating Activities

Cash flows from operating activities for the year to date were $1.6 million, which decreased $132.3 million compared to 2021, reflecting the expected disruptions from the Cardno integration, particularly the financial system migration. Cash flow was also lower due to the increased investment in net working capital to support organic revenue growth and an increase in DSO. Employee incentive payments related to prior years' performance were also higher in 2022 compared to 2021.

Cash Flows Used in Investing Activities

Cash flows used in investing activities for the year to date were $11.6 million, a $42.3 million decrease compared to 2021. This was due primarily to an increase in net proceeds from investments held for self-insured liabilities of $63.0 million, offset by increases in cash used for business acquisitions of $12.6 million and to purchase of property and equipment and intangible assets of $7.9 million.

Cash Flows Used in Financing Activities

Cash flows used in financing activities for the year to date were $10.0 million, a $139.3 million decrease compared to 2021. Higher draws on our revolving credit facility and bank indebtedness of $186.5 million were partly offset by an increase of $14.6 million in repayments for notes payable, software financing obligations and leases, an increase of $14.6 million in repurchases of shares for cancellation, and lower proceeds of $15.3 million from the exercise of share options.

Management’s Discussion and Analysis June 30, 2022 M-19 Stantec Inc.

Capital Management

Our objective in managing Stantec's capital is to provide sufficient capacity to cover normal operating and capital expenditures and to have flexibility for financing future growth. We focus our capital allocations on increasing shareholder value through funding accretive acquisitions in pursuit of our growth strategy while maintaining a strong balance sheet, repurchasing shares opportunistically, and managing dividend increases to our target payout ratio in a sustainable manner.

We manage our capital structure according to our internal guideline of maintaining a net debt to adjusted EBITDA (actual trailing twelve months) of less than 2.0 to 1.0. There may be occasions when we exceed our target by completing acquisitions that increase our debt level for a period of time.

(In millions of Canadian dollars, except ratios)	Jun 30, 2022	Dec 31, 2021
Current and non-current portion of long-term debt	1,389.3	1,245.1
Less: cash and deposits	(169.2)	(193.9)
Bank indebtedness	43.2	7.2
Net debt	1,263.3	1,058.4
Shareholders' equity	2,007.6	2,001.7
Total capital managed	3,270.9	3,060.1
Trailing twelve months adjusted EBITDA from continuing operations (note)	637.0	573.8
Net debt to adjusted EBITDA ratio (note)	2.0	1.8

See the Definitions section of this MD&A for our discussion of non-IFRS measures used.

At June 30, 2022, our net debt to adjusted EBITDA was 2.0x, falling within our stated internal guideline. Our acquisition of Barton Willmore, NCIB share repurchases, and integration of Cardno resulted in higher year to date draws on our revolving credit facility. We expect cash flows from operations and the completion of the Cardno integration to reduce our leverage ratio by the end of this year.

Stantec has senior unsecured notes of $300 million outstanding and syndicated credit facilities consisting of a senior revolving credit facility of a maximum of $800 million, a $310 million term loan in two tranches, and access to additional funds of $600 million through an accordion feature.

We are required to comply with certain covenants as part of our syndicated credit facilities and notes. The key financial covenants include, but are not limited to, ratios that measure our debt relative to our profitability (as defined by the credit facilities agreement).

At June 30, 2022, $53.4 million was available in our revolving credit facility, and we were in compliance with the covenants related to our credit facilities as at and throughout the period ended June 30, 2022.

Shareholders’ Equity

Shareholders’ equity is consistent with December 31, 2021. Net income of $105.5 million earned in the first two quarters of 2022 and share options exercised for cash of $15.4 million were partly offset by shares repurchased under our NCIB of $65.3 million, dividends declared of $39.9 million, and an other comprehensive loss of $8.6 million related to exchange differences on translation of our foreign subsidiaries and unrealized losses on bond investments held for self-insured liabilities.

Our NCIB on the TSX was renewed on November 9, 2021, enabling us to repurchase up to 5,559,312 of our common shares during the period November 16, 2021, to November 15, 2022. We also have an Automatic Share Purchase Plan with a broker that allows the purchase of common shares for cancellation under the NCIB at any time during predetermined trading blackout periods within certain pre-established parameters.

Management’s Discussion and Analysis June 30, 2022 M-20 Stantec Inc.

We believe that, from time to time, the market price of our common shares does not fully reflect the value of our business or future business prospects and that, at such times, the repurchase of outstanding common shares are an appropriate use of available Company funds. We repurchased 1,085,676 common shares for an aggregate price of $65.3 million during the first two quarters of 2022 compared to repurchases of 939,482 common shares for an aggregate price of $50.7 million in the same period of 2021.

Other

Outstanding Share Data

At June 30, 2022, 110,730,097 common shares and 359,984 share options were outstanding. From July 1, 2022, to August 10, 2022, no share options were exercised or forfeited and no shares were repurchased under our Automatic Share Purchase Plan. As such, there were no changes to our common shares and share options since June 30, 2022.

Contractual Obligations

The nature and extent of our contractual obligations did not change materially from those described in the Contractual Obligations section of our 2021 Annual Report (incorporated here by reference). Management believes sufficient liquidity is available to meet our contractual obligations as at June 30, 2022.

Off-Balance Sheet Arrangements

The nature and extent of our off-balance sheet arrangements did not change materially from those described in the Off-Balance Sheet Arrangements section of our 2021 Annual Report (incorporated here by reference).

Financial Instruments and Market Risk

At June 30, 2022, the nature and extent of our use of financial instruments did not change materially from those described in the Financial Instruments and Market Risk section of our 2021 Annual Report (incorporated here by reference).

We continue to hold an interest rate swap to manage the fluctuation in floating interest rates on Tranche C of our term loan. The agreement matures on June 27, 2023 and has the effect of converting the variable interest rate associated with $160 million of our term loan into a fixed interest rate of 2.295% plus an applicable basis points spread.

We also continue to hold total return swap (TRS) agreements with a financial institution to manage a portion of our exposure to changes in the fair value of our shares for certain cash-settled share-based payment obligations. The TRS agreements fix the impact that our share price has on the payments required to settle the obligations for the majority of our restricted share units and deferred share units.

Related-Party Transactions

Transactions with subsidiaries, structured entities, associated companies, joint ventures, and key management personnel are further described in note 34 of our audited consolidated financial statements for the year ended December 31, 2021 (included in our 2021 Annual Report and incorporated here by reference). At June 30, 2022, the nature and extent of these transactions were not materially different from those disclosed in the 2021 Annual Report.

Critical Accounting Estimates, Developments, and Measures

Critical Accounting Estimates

The preparation of consolidated financial statements in accordance with IFRS requires us to make various estimates and assumptions. However, future events may result in significant differences between estimates and actual results.

There has been no significant change in our critical accounting estimates in Q2 2022 from those described in our 2021 Annual Report in the Critical Accounting Estimates, Developments, and Measures section and in note 5 of our December 31, 2021, audited consolidated financial statements (incorporated here by reference), which included considerations for the impacts of the continuing COVID-19 pandemic. The Russian invasion of Ukraine has also contributed to increased economic and financial volatility. These disruptions are expected to be near term and the extent of the impacts on financial performance will depend on certain developments, including the duration of the pandemic, and the resolution of the war in Ukraine and broad sanctions against Russia. Uncertainty remains on the length of time it will take for the financial impacts to reverse. We will continue to monitor the impact on our operations and financial position. Actual results could differ from estimates.

Recent Accounting Pronouncements

Certain amendments disclosed in note 3 of our unaudited interim consolidated financial statements for the quarter ended June 30, 2022 (incorporated by reference) had an effective date of January 1, 2022, but did not have a material impact on the consolidated financial statements or accounting policies for the two quarters ended June 30, 2022.

Future Adoptions

Standards, amendments, and interpretations that we reasonably expect to be applicable at a future date and intend to adopt when they become effective are described in note 6 of our 2021 audited consolidated financial statements (incorporated here by reference).

Definitions of Non-IFRS and Other Financial Measures

This MD&A includes references to and uses measures and terms that are not specifically defined in IFRS and do not have any standardized meaning prescribed by IFRS. These measures and terms are defined below. These non-IFRS and other financial measures may not be comparable to similar measures presented by other companies. We believe that the measures defined here are useful for providing investors with additional information to assist them in understanding components of our financial results.

Adjusted Measures

We use several adjusted financial measures because we believe they are useful for providing securities analysts, investors, and other interested parties with additional information to assist them in understanding components of our financial results (including a more complete understanding of factors and trends affecting our operating performance). These adjusted measures also provide supplemental measures of operating performance and improve comparability of operating results from one period to another, thus highlighting trends that may not otherwise be apparent when relying solely on IFRS financial measures. Unless otherwise noted, a reconciliation of these adjusted measures to the most directly comparable IFRS measure is included on page M-7.

Adjusted EBITDArepresents netincome from continuing operations before interest expense, income taxes, depreciation of property and equipment, depreciation of lease assets, amortization of intangible assets, impairment charges and reversals thereof, acquisition, integration and restructuring costs, and other adjustments for other specific items that are significant but are not reflective of our underlying operations. Specific items are subjective; however, we use our judgement and informed decision-making when identifying items to be excluded in calculating our adjusted measures. We use adjusted EBITDA as a measure of pre-tax operating cash flow. There is no directly comparable IFRS measure for adjusted EBITDA.

Management’s Discussion and Analysis June 30, 2022 M-22 Stantec Inc.

Adjusted Net Incomerepresents net income from continuing operations excluding the amortization of intangibles acquired through acquisitions, impairment charges and reversals thereof, acquisition, integration and restructuring costs, and adjustments for other specific items that are significant but are not reflective of our underlying operations, all on an after-tax basis. Specific items are subjective; however, we use our judgement and informed decision-making when identifying items to be excluded in calculating our adjusted measures. We use adjusted net income as a measure of overall profitability. The most comparable IFRS measure for adjusted net income is net income.

Adjusted Earnings Per Share (EPS) is calculated by dividing adjusted net income (defined above) by the basic and diluted weighted average number of shares outstanding, respectively. The most comparable IFRS measure for adjusted EPS is earnings per share.

Adjusted Return on Invested Capital (ROIC) represents our full year adjusted net income (defined above) before tax-adjusted interest relative to our average aggregate net debt and adjusted shareholders’ equity, determined annually. Average net debt and adjusted shareholders’ equity are calculated using balances from past years. Adjusted shareholders’ equity includes the impact of adjusted net income from continuing operations (as defined above). We use adjusted ROIC to evaluate annual returns generated on our debt and equity capital. There is no directly comparable IFRS measure for adjusted ROIC or adjusted net income before tax-adjusted interest. The most directly comparable measure for adjusted shareholders’ equity is shareholders’ equity.

Net Debt to Adjusted EBITDA. As part of our assessment of our capital structure, we monitor net debt to adjusted EBITDA. It is defined as the sum of (1) long-term debt, including current portion, and bank indebtedness, less cash and deposits, divided by (2) adjusted EBITDA (as defined above). There is no directly comparable IFRS measure for net debt to adjusted EBITDA. Net debt to adjusted EBITDA is quantified in the Liquidity and Capital Resources section on page M-18.

Days Sales Outstanding (DSO). DSO is a metric we use to evaluate the efficiency of our working capital. It represents the average number of days to convert our trade and other receivables, unbilled receivables, contract assets, and deferred revenue to cash. We calculate DSO by annualizing gross revenue for the quarter as reported under IFRS. There is no directly comparable IFRS measure for DSO.

Free Cash Flow. Free cash flow is a non-IFRS measure we use to monitor the availability of discretionary cash as part of our capital management. It is defined as operating cash flows less capital expenditures and net lease payments. There is no directly comparable IFRS measure for free cash flow. A reconciliation of cash flows from operating activities as reported under IFRS to free cash flow is included in the Additional Reconciliations of Non-IFRS Financial Measures on page M-24.

Margin. We calculate margin as a percentage of net revenue and apply this calculation to various non-IFRS and other financial measures. We monitor margin or percentages of net revenue for adjusted EBITDA, adjusted net income, project margin and administrative and marketing expenses in comparison to our internal targets. There is no directly comparable IFRS measure for margin.

Organic Growth (Retraction) and Acquisition Growth. To evaluate our performance, we quantify the change in revenue and backlog as either related to organic growth (retraction), acquisition growth, or the impact of foreign exchange. Revenue earned by acquired companies in the first 12 months following an acquisition is reported as growth from acquisitions and thereafter as organic growth (retraction). Backlog from acquired companies is reported as growth from acquisitions in the quarter acquired and thereafter as organic growth (retraction). Organic growth (retraction) excludes the impact of foreign currency fluctuations. From time to time, we also quantify the impacts of certain unusual events to organic growth (retraction) to provide useful information to investors to help better understand our financial results. There are no directly comparable IFRS measures. Reconciliations of net revenue by reportable segment and business operating unit and additional information on backlog are included in the Financial Performance section for revenue on pages M-10 to M-11 and for backlog on page M-12.

Management’s Discussion and Analysis June 30, 2022 M-23 Stantec Inc.

Constant Currency Basis and Impact of Foreign Exchange. We monitor the impact of changing foreign exchange rates, quantify foreign exchange impacts, and, from time to time, prepare analyses on a constant currency basis (i.e., excluding the impact of foreign exchange) to better understand changes in activity. There are no directly comparable IFRS measures.

Compound Annual Growth Rate (CAGR). CAGR is a metric we use to evaluate the growth in our business. It represents the growth rate over a period of time on an annual compounded basis. There is no directly comparable IFRS measure for CAGR.

Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our CEO and CFO evaluated our disclosure controls and procedures (defined in the US Securities Exchange Act Rules 13a–15(e) and 15d–15(e)) as of the end of the period covered by this quarterly report. Based on the evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective at such date.

Changes in Internal Controls over Financial Reporting

There has been no change in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Rules 13a–15 or 15d–15 under the Securities Exchange Act of 1934 that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Risk Factors

For the two quarters ended June 30, 2022, there has been no significant change in our risk factors from those described in our 2021 Annual Report (incorporated here by reference), except for the following:

War in Ukraine may result in additional risks to our business.

Many countries around the world, including the US, Canada and the UK, have implemented sanctions on conducting business with Russian and Belarusian entities and individuals. Non-compliance with such sanctions may expose Stantec to government enforcement as well as reputational risk.

Stantec does not currently have any offices, projects, or clients in Ukraine, Russia or Belarus. We will continue to perform due diligence to ensure that we are not working with any sanctioned entities or individuals.

These describe the management expectations and targets by which we measure our success and assist our shareholders in understanding our financial position as at and for the periods ended on the dates presented in this report. Readers are cautioned that this information may not be appropriate for other purposes.

By their nature, forward-looking statements require us to make assumptions and are subject to inherent risks and uncertainties. There is a significant risk that predictions, forecasts, conclusions, projections, and other forward-looking statements will not prove to be accurate. We caution readers of this report not to place undue reliance on our forward-looking statements since a number of factors could cause actual future results, conditions, actions, or events to differ materially from the targets, expectations, estimates, or intentions expressed in these forward-looking statements.

Future outcomes relating to forward-looking statements may be influenced by many factors and material risks. For the two quarters ended June 30, 2022, there has been no significant change in our risk factors from those described in our 2021 Annual Report (incorporated here by reference).

Assumptions

In determining our forward-looking statements, we consider material factors, including assumptions about the

performance of Canadian, US, and various international economies and their effect on our business. The assumptions we made at the time of publishing our annual targets and outlook for 2022 are listed in the Cautionary Note Regarding Forward-Looking Statements section of our 2021 Annual Report (incorporated here by reference). The following information updates and therefore supersedes those assumptions.

•In our 2021 Annual Report, our outlook forecast assumed that the Canadian dollar would strengthen compared to the US dollar and weaken compared to the British pound. In the first two quarters of 2022, the average US dollar increased from $1.25 (US$0.80) reported in 2021 to $1.27 (US$0.79) and the average British pound decreased slightly from $1.73 (£0.58) reported in 2021 to $1.65 (£0.61).

•Our effective income tax rate, without discrete transactions, is expected to be in the range of 23.2% to 24.2% and was considered based on the tax rates in place as of December 31, 2021, as well as our mix of expected average earnings for the countries we operate in.

•The Canadian unemployment rate—5.9% at the end of 2021—improved to 4.9% as of June 2022 and is expected to further improve in 2022. In the United States, the unemployment rate—3.9% at the end of 2021—improved to 3.6% as of June 2022.

•In the United States, the forecasted seasonally adjusted annual rate of total housing starts for 2022 was expected to be 1.6 million. This has since been revised to 1.5 million at June 2022. In Canada, the number of total housing starts in 2022 was forecasted to be in line with 2021. As of Q2 2022, new housing construction in Canada decreased 7% over year-to-date Q2 2021.

Management’s Discussion and Analysis June 30, 2022 M-26 Stantec Inc.

•The American Institute of Architects ABI (architectural billing index) has decreased to 53.2 as of June 2022 from 58.0 at the end of March 2022, as rising inflation, interest rates, and shortage of certain building materials leave the future looking increasingly unclear.

The preceding list of factors is not exhaustive. Investors and the public should carefully consider these factors, other uncertainties and potential events, and the inherent uncertainty of forward-looking statements when relying on these statements to make decisions with respect to our Company. The forward-looking statements contained herein represent our expectations as of August 10, 2022, and, accordingly, are subject to change after such date. Except as may be required by law, we do not undertake to update any forward-looking statement, whether written or verbal, that may be made from time to time. In the case of the ranges of expected performance for fiscal year 2022, it is our current practice to evaluate and, where we deem appropriate, to provide updates. However, subject to legal requirements, we may change this practice at any time at our sole discretion.
