Ameresco director and general counsel retires, remains as special legal advisor

This is a leadership transition, not an operating update. David J. Corrsin resigned as a Class II director and retired as executive vice president and general counsel effective August 17, 2026. 〔0〕

The practical impact is softened by continued access to his expertise. Corrsin will remain with Ameresco as a special legal advisor, limiting the immediate loss of institutional and legal knowledge. 〔1〕

Versus expectations, this is best read as neutral. The filing contains no financial guidance, strategic change, stated disagreement, or indication of a board dispute. Corrsin had served as a director since Ameresco’s formation in 2000, so the main change is the formal loss of a longtime board and executive role rather than an abrupt operational disruption. 〔2〕
