Insider cluster: 2 insiders, $4.6M total
Actionable Insight • Neutral

The sales align with typical post-exercise divestment by executives and are not unusually large relative to Iron Mountain's $31B market cap (~0.015% of market cap). No immediate red flags, but monitor for additional selling or absence of buying in next quarter.
