AMT insider buying and selling over the past year

Over the past year AMERICAN TOWER CORP /MA/ insiders filed 8 open-market Form 4 trades — 2 purchases worth $1.49M and 6 sales worth $21.86M — which makes them net sellers by $20.37M.

Most of the selling was pre-scheduled: 5 of the 6 sales (83.3%) were flagged as Rule 10b5-1 plan trades, which are set up in advance and say less about an insider's current view than discretionary sales.

The average open-market sale price was $190.39; the last close of $185.27 is 2.7% below that level, so sellers exited above the current price. The single largest trade was a sale of 41,209 shares worth $7.87M on 2026-03-02. Since the most recent filing the stock has moved -0.5%, from $186.12. Insiders paid an average of $181.04 per share for their open-market purchases; against the last close of $185.27 that cost basis is sitting on a gain at +2.3%.
