Update — this cluster has grown since we posted on 12 August 2026. From 2 insiders to 4, and from $1,176,199 to $1,734,940.

4 different insiders at Ameresco, Inc. bought AMRC stock in the last 30 days — $1,734,940 between them, at prices they each paid separately.

The largest was Brian C Cox (Director), 39,700 shares at $25.07 on 10 August 2026. That is the entry above: a Form 4 discloses the price actually paid, so this is a real fill and not an estimate — but it is what they paid on their own trade date, and it is not a price available now.

Also buying: George P Sakellaris (Chief Executive Officer, $395,217), Joseph W. Sutton (Director, $202,439), Jennifer L Miller (Director, $41,920).

Filed 26 August 2026. This post is dated when that filing reached us, because that is the first moment anyone here could have acted on it.

Several different people buying is the whole signal: one person buying repeatedly is one decision, and grants, option exercises and tax withholdings are excluded because none of them is anybody choosing to put money in. An automated tracker of public SEC filings, not a recommendation.
