Ameresco, Inc., a clean technology integrator, provides a portfolio of energy efficiency and renewable energy supply solutions in the United States, Canada, and internationally. It offers energy efficiency, infrastructure upgrades, energy security and resilience, asset sustainability, and renewable energy solutions for businesses and organizations. The company operates through U.S. Regions, U.S. Federal, Canada, and Non-Solar Distributed Generation segments. It designs, develops, engineers, and installs projects that reduce the energy, as well as operations and maintenance (O&M) costs of its customers' facilities. The company's projects primarily include various measures customized for the facility and designed to enhance the efficiency of building systems, such as heating, ventilation, cooling, and lighting systems. It also offers renewable energy solutions and services, such as the construction of small-scale plants that the company owns or develops for customers that produce electricity, gas, heat, or cooling from renewable sources of energy and O&M services; and electricity, processed renewable gas fuel, and heat or cooling produced from renewable sources of energy. In addition, the company sells photovoltaic (PV) solar energy products and systems, as well as provides consulting and enterprise energy management services; and owns and operates a wind power project located in Ireland. It serves the federal, state, and local governments, as well as healthcare and educational institutions, airports, public housing authorities and public universities, and commercial and industrial customers.

Ameresco, Inc. was founded in 2000 and is headquartered in Framingham, Massachusetts.
Ameresco designs and installs energy efficiency and renewable-generation projects for government, corporate, and utility customers, earning upfront construction fees plus long-term maintenance contracts. The mix is lumpy: roughly 58% is one-time project work, while a growing O&M and energy-asset stream provides a recurring floor beneath the construction cycle.
Each project generates a one-time construction margin, but the compounding asset is the O&M backlog that collects a thin recurring fee for the life of every installed system, gradually shifting the revenue base from lumpy EPC work toward annuity-like maintenance income.
| Project Revenue | $0.3B |
| Energy Asset Revenue | $0.1B |
| O&M Revenue | $0.0B |
| Other | $0.0B |
Business quality (Mixed): Thin construction margins (18% gross, 9% operating) and a recurring base still under a quarter of revenue make this a low-multiple business by nature; the data-center pivot aims to raise scale, but has not yet moved the income statement.
Valuation: At 49× earnings, AMRC trades 111% above the Construction average (23×).
