Ameresco (AMRC) Director Nickolas Stavropoulos Exercises Options, Sells Shares

What Happened

Nickolas Stavropoulos, a director of Ameresco (AMRC), exercised stock options and sold the resulting shares. He exercised 16,100 options (400 on Feb 19, 15,700 on Feb 20) at $16.33 per share, costing $262,913 in aggregate, and sold those 16,100 shares in open-market transactions for a combined reported proceeds of $549,755 (sales ranged $34.00–$34.53).
The filing also shows matching derivative “Disposed” entries at $0.00 for the exercised shares (typical when shares are surrendered/withheld in connection with an exercise or tax withholding). Rough arithmetic from reported amounts implies roughly $287k in net proceeds (sales minus exercise cost).

Context

This sequence (exercise of options followed by immediate open-market sales under a 10b5-1 plan) is a common way insiders realize option value while complying with prearranged trading rules. The derivative “Disposed” lines at $0.00 typically reflect shares withheld or surrendered to cover taxes/exercise obligations rather than a market sale.
