IRM Insider Buying & Government Contracts (2026)

IRM insider buying and selling over the past year

Over the past year IRON MOUNTAIN INC insiders filed 16 open-market Form 4 trades — 1 purchases worth $3.0K and 15 sales worth $77.51M — which makes them net sellers by $77.50M.

Most of the selling was pre-scheduled: 14 of the 15 sales (93.3%) 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. Activity clustered in 2026-03 (6 trades) and 2025-11 (3 trades); the latest filing in this window is dated 2026-03-19. The average open-market sale price was $103.02; the last close of $112.68 is 9.4% above that level, so sellers left upside on the table. The single largest trade was a sale of 197,318 shares worth $21.13M on 2026-03-04. Since the most recent filing the stock has moved +7.4%, from $104.94. Insiders paid an average of $89.52 per share for their open-market purchases; against the last close of $112.68 that cost basis is sitting on a gain at +25.9%.
