Ameresco, Inc.

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.

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.
