Ameresco (AMRC) CFO Mark Chiplock Converts 1,625 RSUs

What Happened

• Mark Chiplock, EVP, Chief Financial Officer & Chief Accounting Officer of Ameresco, had 1,625 derivative units converted into 1,625 shares on 2026-09-10 (transaction code M — exercise/conversion of derivative). The same reporting line shows 1,625 shares disposed the same day. The Form 4 lists $0.00 per share for both the acquisition and disposition (consistent with RSU conversion mechanics where there is no exercise price).

Key Details

• Transaction date: 2026-09-10; Form 4 filed: 2026-09-14 (timely; filed two business days after the transaction).
• Price reported: $0.00 for both acquired and disposed shares (reflects RSU conversion rather than a cash purchase).
• Shares acquired: 1,625; shares disposed: 1,625 (both reported as derivative transactions).
• Shares owned after the transaction: not specified in the filing excerpt provided.
• Footnotes (from the filing): F1 — each RSU represents a contingent right to one share; F2 — RSUs vest over two years (25% every six months); F3 — these RSUs were granted on various dates.
• Transaction code: M = exercise or conversion of a derivative security (here, RSUs).

Context

• This filing documents RSU conversions (no exercise price) rather than a cash purchase or sale for market gain. The matching acquired and disposed amounts at $0.00 commonly reflect conversion of vested RSUs and same-day share surrender/net settlement for tax withholding or settlement mechanics; the filing does not state an open-market sale or sale price. As always, conversions/withholdings are routine compensation events and do not alone signal the insider’s market view.
