Chiplock Mark 4

What Happened
Mark Chiplock, Ameresco’s Executive VP, CFO & CAO, had multiple equity transactions reported. On March 10, 2026 he was granted RSU awards (20,000 and 3,500 RSUs) and converted/exercised 750 derivative securities (reported at $0.00). On March 12, 2026 he sold 273 shares in an open-market transaction at $25.31 per share for a total of $6,910. The 273-share sale was executed pursuant to an automatic sell-to-cover instruction to cover withholding taxes related to RSU vesting.

Key Details

• Transaction dates: March 10, 2026 (awards, conversion/exercise) and March 12, 2026 (open-market sale). Filing date: March 12, 2026 (period of report March 10). Filing appears timely.
• Sale: 273 shares sold @ $25.31 for $6,910 (open market). Footnote F1: sale was automatic sell-to-cover for taxes on RSU vesting.
• Awards/derivatives: Grants of 20,000 RSUs and 3,500 RSUs (each RSU = right to one share; footnote F3). A 750-share exercise/conversion of derivative securities is reported (entries show $0.00 per share).
• Vesting notes: Option/derivative grant noted to vest 20% on each anniversary over five years (F2). RSUs vest over two years with 25% vesting every 6 months (F4).
• Shares owned after transaction: Not specified in the provided filing excerpts.

Context

• The sale was a routine sell-to-cover to satisfy tax withholding tied to RSU vesting, not an open-market sell intended to liquidate a position.
• The filing includes derivative activity (exercise/conversion and RSU awards). For retail investors, RSU grants and option vesting are common compensation events; the sell-to-cover is administrative.
• No indication in the filing of a 10% owner change or gifts. The transactions are compensation-related and administrative rather than an outright discretionary sale signaling intent.
