Stantec’s record $8.6B backlog, up 9.5% YoY, anchors robust growth across water, buildings, and energy transition verticals. As the firm enters 2026, disciplined margin expansion, operational leverage, and AI-driven productivity set the stage for continued outperformance, while management signals strong M&A appetite amid shifting sector multiples.
Summary
- Backlog Expansion Secures Growth: Record $8.6B backlog, up 9.5%, underpins revenue visibility and multi-sector momentum.
- Margin Execution Outpaces Targets: Early achievement of 2026 margin range highlights operational discipline and pricing power.
- M&A and AI Integration Shape Strategic Edge: Leadership prioritizes accretive deals and AI-enabled delivery, reinforcing scale advantages.
Performance Analysis
Stantec delivered double-digit revenue growth and record profitability in 2025, with net revenue up 10.7% to $6.5B and adjusted EBITDA margin reaching 17.9%. Growth was balanced: 5% organic and 3.9% from acquisitions, with all business operating units (BOUs) and regions contributing positively. The water segment, now 22% of total business, continued its multi-year double-digit organic growth streak, while the buildings business benefited from the Page acquisition and sustained demand for mission-critical facilities and data centers.
Cash flow generation was a standout, with operating cash flow up 43.1% and free cash flow conversion at 1.3x net income, reflecting disciplined working capital management. DSO improved by eight days YoY, and net debt/EBITDA of 1.3x leaves significant capacity for future M&A. Dividend growth of 8.9% signals confidence in ongoing cash generation. The $8.6B backlog, representing 13 months of work, was driven by both organic and acquired growth, with notable gains in water, buildings, and global infrastructure.
- Water Business Sustains Leadership: 11% organic growth, now 22% of revenue, driven by large wastewater and infrastructure projects globally.
- Buildings and Mission-Critical Facilities Surge: Over 30% revenue increase, with Page integration and data center wins fueling momentum.
- Operational Leverage Drives Margin: Adjusted EBITDA margin reached the 2026 target range a year early, aided by utilization and cost discipline.
Stantec’s diversified portfolio and global reach have insulated performance from regional volatility, while execution strength and sector tailwinds reinforce the outlook for 2026.

Strategic Positioning
1. Backlog and Sector Diversification
Stantec’s $8.6B backlog, up 9.5% YoY, provides strong revenue visibility and is diversified across water, buildings, infrastructure, and energy transition projects. This breadth supports resilience against sector or geographic shocks and enables proactive resource allocation.
2. Margin Expansion and Operational Discipline
Margin gains were achieved through both project execution and back-office efficiency, with utilization and cost control driving a 90 basis point YoY improvement in adjusted EBITDA margin. Leadership expects further gains as digital strategies and high-value centers scale.
3. AI-Enabled Delivery and Value Pricing
AI is being embedded into workflows, not as a standalone product but as a lever for margin and delivery quality. Management emphasizes that AI enhances throughput and risk management, supporting higher revenue per employee and value-based pricing, especially on fixed-fee projects.
4. M&A as a Growth Lever
Stantec remains highly active in M&A, targeting value-accretive deals that align with strategic verticals and digital capabilities. While public market valuation resets may delay some transactions, management is prepared to act as opportunities arise, especially as AI and scale demands drive sector consolidation.
5. Sector Tailwinds and Geographic Balance
Growth drivers include infrastructure stimulus, defense spending, water security, and energy transition, with the U.S., Canada, and global markets all contributing. Data center and mission-critical facility demand is particularly robust, while mining and energy transition projects in South America and Europe add further growth levers.
Key Considerations
Stantec’s 2025 results position the company for continued outperformance, but the evolving macro and competitive landscape require close monitoring. Investors should weigh the following:
Key Considerations:
- Backlog Quality and Duration: 13 months of work in backlog provides visibility, but sector mix and project timing could impact revenue conversion rates.
- AI Integration as Competitive Moat: Early operationalization of AI enhances delivery, but the pace of industry adoption and client acceptance will shape margin durability.
- M&A Pipeline and Pricing Discipline: Leadership is focused on accretive deals with strategic fit, yet private seller expectations may lag public market resets, affecting timing.
- Infrastructure and Energy Transition Stimulus: U.S. IIJA funding and global energy transition projects provide multi-year tailwinds, but depend on policy continuity and execution.
- Margin Leverage from Utilization and Digitalization: Further gains hinge on continued utilization improvements, scale in high-value centers, and digital workflow adoption.
Risks
Execution risk remains around integrating acquisitions, especially as sector multiples shift and consolidation accelerates. Margin expansion depends on sustained utilization and project discipline, with labor costs and competitive pricing pressure as persistent headwinds. Policy risk—particularly around infrastructure funding and defense spending—could impact backlog conversion and project starts, while AI adoption introduces both efficiency upside and potential disruption if industry norms shift faster than anticipated.
Forward Outlook
For Q1 2026, Stantec guided to:
- Net revenue growth of 8.5% to 11.5%, driven by both organic and acquired contributions.
- Adjusted EBITDA margin in the 17.6% to 18.2% range, reflecting ongoing operational leverage.
For full-year 2026, management expects:
- 15% to 18% adjusted EPS growth, underpinned by backlog execution and efficiency gains.
Management highlighted several factors that will influence 2026:
- Continued strength in water, buildings, and energy transition verticals.
- Active pursuit of value-accretive M&A, with flexibility to deploy capital toward buybacks if share price remains depressed.
Takeaways
Stantec’s record backlog, margin outperformance, and disciplined capital allocation reinforce its status as a consolidator and sector leader.
- Backlog-Driven Visibility: Multi-sector backlog at record levels supports revenue confidence and multi-year growth, especially in water and mission-critical facilities.
- Margin and Productivity Levers: Early achievement of 2026 margin targets and AI-enabled delivery position Stantec to protect and expand profitability even in a competitive labor environment.
- Strategic Flexibility: Capital deployment remains balanced between M&A and opportunistic buybacks, with management signaling readiness to act as sector valuations evolve.
Conclusion
Stantec exits 2025 with robust backlog, sector diversification, and operational momentum, all underpinned by disciplined execution and a clear strategic focus. The company’s proactive embrace of AI and sustained M&A appetite signal continued leadership in an industry facing rapid technological and structural change.
Industry Read-Through
Stantec’s results reinforce that scale, digital enablement, and backlog quality are decisive advantages in the engineering and infrastructure services sector. The company’s experience suggests that AI integration is moving from pilot to production, raising the bar for smaller competitors and likely accelerating sector consolidation. Backlog expansion and high-value project wins in water, energy transition, and mission-critical facilities point to multi-year industry tailwinds, but also highlight the importance of operational discipline as stimulus programs mature and labor markets remain tight. Investors should monitor how leading firms use digital and capital scale to capture share and defend margins as the sector evolves.
