Actionable Insight • Neutral

This insider selling cluster is too small to warrant a trading signal. Monitor for any material increase in selling volume (e.g., >$50M in a month) or a change in pattern (e.g., CEO accelerating sales ahead of earnings). For now, treat as noise.

Executive Summary

CEO William Meaney and EVP Mark Kidd sold a combined $1.98M in open-market shares over a 7-day window ending September 1, 2026. The total represents ~0.006% of IRM's $33.3B market cap, making this a routine, immaterial cluster. Additional same-day sales by Meaney (including option exercises) brought total insider cash-out to ~$5.66M, still trivial relative to market cap.

Key Facts

  • CEO William Meaney sold 11,332 shares at $113.45 for $1.29M on 2026-09-01
  • EVP Mark Kidd sold 6,000 shares at $115.60 for $694K on 2026-09-01
  • Total cluster value $1.98M equals ~0.006% of IRM's $33.3B market cap
  • Cross-filing context shows additional CEO sales and option exercises totaling ~$5.66M on the same day, still immaterial
  • No 10b5-1 plan or routine pattern identified; sales appear discretionary but insignificant in size

Financial Impact

Insider selling of $1.98M (cluster) to $5.66M (including cross-filing context) is negligible relative to $33.3B market cap

dilution

Risk Factors

  • CEO exercised options and sold shares, which could indicate tax planning rather than a bearish view
  • If insider selling accelerates to >0.5% of market cap, it would become a meaningful signal
