## Geography

Ameresco operates primarily across North America and Europe, with revenue disclosed by reportable segment rather than by country. In 2025, North America Regions and U.S. Federal remained the largest revenue pools, while Europe grew sharply and became a much more important contributor. The business is exposed to regional construction cycles, weather patterns, and public-sector procurement timing, which can affect project execution and revenue recognition. Its European activity appears to be expanding through project business and joint ventures, while North American demand is tied to government, utility, and institutional infrastructure spending.

- **North America Regions** (45.8%) — 2025 segment revenue share based on disclosed segment revenues.
- **U.S. Federal** (15.2%) — 2025 segment revenue share based on disclosed segment revenues.
- **Europe** (27.4%) — 2025 segment revenue share based on disclosed segment revenues.
- **Renewable Fuels** (8.2%) — Primarily North American operating assets.
- **All Other** (3.5%) — Residual segment, mostly North America based on disclosure.

- North America is the core operating region and includes U.S. regions and Canada
- U.S. Federal is a separate revenue segment tied to federal procurement
- Europe is a growing market and expanded materially in 2025
- Operations are influenced by winter weather, storms, and construction seasonality
- Regional public-sector budgets and procurement cycles affect project timing
- No country-level revenue disclosure was provided in the excerpts

## Strategy

Ameresco’s strategy is centered on expanding its role as a full-service energy infrastructure partner rather than a pure installer. The company emphasizes budget-neutral structures such as ESPCs and PPAs, which help win projects where customers want savings and decarbonization without upfront capital. It is also growing through renewable energy development, owned assets, and long-term O&M contracts that create more recurring revenue. Acquisitions and joint ventures are used to broaden service capabilities and extend geographic reach, especially in Europe.

- **Expand budget-neutral project pipeline** (short-term) — ESPCs and PPAs reduce customer capex barriers and are central to winning large public-sector projects.
- **Increase recurring revenue from owned assets and O&M** (medium-term) — Long-term contracts and energy asset revenue improve visibility versus one-time project work.
- **Broaden geographic and technical capabilities** (medium-term) — Acquisitions and joint ventures help the company enter new markets and offer a wider solution set.

- Win larger, multi-year projects through budget-neutral financing structures
- Expand recurring revenue from O&M and energy supply contracts
- Grow owned renewable energy assets and distributed generation portfolio
- Use acquisitions and joint ventures to add capabilities and geography
- Deepen relationships with public-sector, utility, and institutional customers
- Invest in technical expertise and employee training to support complex projects

## Risks

Ameresco’s revenue depends on continued demand for energy efficiency and renewable solutions, so slower market adoption or weaker public-sector spending would reduce project flow. The business also has a long and variable sales cycle, which makes revenue timing sensitive to procurement delays, permitting, and customer decision-making. A large portion of revenue comes from government entities, so contract terms, funding availability, and compliance requirements can materially affect results. In addition, the company faces execution risk from construction cycles, supply-chain disruptions, inflation, weather, and cybersecurity threats across both owned assets and third-party systems.

- **Weak demand for energy efficiency and renewable solutions** [high] — The company’s growth depends on continued customer adoption of these projects; slower market growth would reduce bookings and revenue.
- **Long and variable selling cycle** [high] — Projects often require audits, proposals, approvals, and financing arrangements before revenue can be realized.
- **Government contracting and funding risk** [high] — About 61% of revenue came from government entities, so changes in budgets, procurement rules, or contract disputes can materially affect results.
- **Construction, weather, and seasonality risk** [medium] — Project execution depends on weather, site access, and construction cycles, which can delay completion and increase costs.
- **Supply-chain and inflation pressure** [medium] — Delays and higher input costs can compress margins on fixed-price or long-duration projects.
- **Cybersecurity risk** [medium] — The company owns and operates energy assets and relies on digital systems and vendors, increasing exposure to attacks and outages.

- Demand risk if energy efficiency and renewable project markets grow more slowly than expected
- Long sales and procurement cycles can delay contract awards and revenue recognition
- Government contracting exposure creates compliance, funding, and contract-termination risk
- Construction and weather seasonality can delay project completion and increase costs
- Supply-chain disruptions and inflation can raise material, shipping, and labor costs
- Cybersecurity incidents could disrupt owned assets, operations, or sensitive data

## Accounting

Ameresco’s reported results are highly sensitive to revenue recognition timing because many projects are accounted for over time based on costs incurred relative to expected total costs. That means quarterly revenue can move materially when project phases change, when customer approvals are delayed, or when a project is no longer probable, as seen in the reversal of previously recognized revenue on a solar project. The company also has meaningful seasonality and construction-cycle effects, so winter weather and site access can shift revenue and margin between quarters. In addition, project financing, owned energy assets, and long-term contracts require judgment around capitalization, asset values, and the timing of financing-related cash flows and related obligations.

- **Revenue recognition on long-duration projects** — Quarterly revenue and margin volatility
- **Revenue reversals and project probability assessments** — Reported revenue and earnings
- **Seasonality and construction-cycle timing** — Quarter-to-quarter comparability
- **Project financing and owned asset accounting** — Leverage, asset base, and financing cash flows

- Over-time revenue recognition on project work can shift revenue between quarters
- Revenue reversals can occur if a project closing or sale is no longer probable
- Seasonality and construction cycles affect comparability across quarters
- Owned energy assets and project financings require judgment on asset values and obligations
- Long-term O&M and energy supply contracts create recurring revenue timing considerations
- Estimates of total project costs affect margin recognition and reported profitability
