Ameresco (AMRC) EVP David Corrsin Exercises Options

What Happened

David J. Corrsin, EVP, General Counsel and a director of Ameresco (AMRC), exercised options on February 27, 2026 to acquire 20,000 shares of Class A common stock at an exercise price of $4.64 per share, paying $92,800. The filing also shows a contemporaneous disposition of 20,000 derivative shares at $0.

Context

For retail investors: an option exercise is an acquisition of shares by an insider. When an equal number of shares are shown as disposed at $0 in the same filing, it most often reflects share withholding or surrender to satisfy tax withholding or exercise costs (a net/settlement), not necessarily an open‑market sale.
The filing is informational and factual — it shows the mechanics of option exercise and related settlement; it does not state the insider’s market view.
