Ameresco

What Ameresco does

Ameresco, Inc. (NYSE: AMRC) is a publicly traded, full-service energy infrastructure solutions provider founded in 2000 and headquartered in Framingham, Massachusetts. The company designs, builds, finances, owns, and operates energy efficiency, distributed generation, renewable energy, and storage assets for federal, state and municipal governments, electric utilities, data centers, K-12 and higher education institutions, healthcare facilities, public housing authorities, and commercial/industrial customers across North America and Europe. Core product lines include solar PV, battery energy storage systems (BESS), microgrids with island-mode capability, geothermal heat pumps, cogeneration/CHP, renewable natural gas (RNG), biomass, hydropower, wind, LED lighting retrofits, HVAC and building controls, advanced metering infrastructure (AMI), EV charging, and emerging small modular reactor (SMR/MMR) deployments, all supported by the proprietary AssetPlanner enterprise asset management SaaS platform.

The company monetizes work through a mix of one-time project revenue (construction of solar, storage, geothermal, and ESPC projects), long-duration recurring Operations & Maintenance (O&M) contracts, and revenue from 750 MW of owned energy generation assets including solar, battery storage, and RNG facilities. Customer-facing commercial structures include Energy Savings Performance Contracts (ESPCs), Power Purchase Agreements (PPAs), Design-Build-Own-Operate-Maintain (DBOOM) arrangements, and Energy-as-a-Service (EaaS), enabling budget-neutral infrastructure modernization. Roughly 64% of EBITDA is derived from recurring revenue sources, providing cash-flow stability layered on top of project-driven lumpiness. Ameresco supplements project economics with tax-credit transfer monetization (ITCs) under a private shelf facility with CounterpointeSRE and Barings, and partners with infrastructure capital providers including HASI, Nuveen, and Bank of America for debt and balance-sheet support.

The customer base is heavily weighted toward U.S. federal and municipal government projects (e.g., U.S. Army Fort Polk geothermal, U.S. Navy/Hawaiian Electric Kūpono project, Cook County, Miami-Dade, Montgomery County Public Schools), with supplementary utility (Southern California Edison, Vattenfall) and industrial (Republic Services) contracts. As of FY2025, the company reported $1.93 billion in revenue (up 9% year-over-year), a project backlog exceeding $5 billion, total revenue visibility over $10 billion, and 140+ million metric tons of CO₂ equivalent avoided since inception. The company completed its 25th anniversary in 2026 and underwent a leadership restructuring effective April 1, 2026, appointing two Co-Presidents and a new COO while spinning off its biofuels business into the $1.8 billion Neogenyx Fuels joint venture with HASI.
