Rhea-AI Filing Summary

William L. Meaney, President and CEO of Iron Mountain Inc. (IRM), reported stock option activity on Form 4. On 09/03/2025 he exercised options to acquire 69,125 shares at an exercise price of $36.588 per share under a Rule 10b5-1 trading plan adopted August 18, 2023, and concurrently sold 69,125 shares at $89.564 per share. Following these transactions Meaney directly beneficially owns 69,125 shares and indirectly owns 295,650 shares transferred to a Grantor Retained Annuity Trust (GRAT) on 11/29/2024 (that transfer is exempt under Rule 16a-13). The filing notes the option pool includes a fully vested option right to purchase 829,506 shares and shows 207,375 option shares remain held directly after the reported transactions.

Positive

Transaction executed pursuant to a Rule 10b5-1 plan, providing pre-arranged trading plan disclosure (adopted August 18, 2023).
Exercise used vested options; filing states the option right to purchase 829,506 shares is fully vested.

Negative

Sale of 69,125 shares at $89.564 reduced immediate direct holdings to 69,125 shares.
Large indirect holding placed in a GRAT (295,650 shares transferred 11/29/2024) which may limit direct voting control (transfer noted as exempt under Rule 16a-13).

Insights

TL;DR Insider exercised vested options and sold an equal amount under a 10b5-1 plan, realizing the spread between $36.588 and $89.564.

The filing documents a routine executive exercise-and-sale where 69,125 option shares were exercised at $36.588 and sold at $89.564 on 09/03/2025 under a previously adopted 10b5-1 plan. The report confirms the transaction mechanics, post-transaction direct beneficial ownership of 69,125 shares, and an indirect holding of 295,650 shares placed in a GRAT on 11/29/2024 (exempt under Rule 16a-13). These are transactional disclosures rather than operational or financial results.

TL;DR Transactions were executed under a documented 10b5-1 plan and include a GRAT transfer previously reported as exempt.

The Form 4 shows compliance with Section 16 reporting: the exercise and sale were conducted pursuant to a 10b5-1 plan adopted August 18, 2023, and the GRAT transfer dated 11/29/2024 is explicitly identified as exempt under Rule 16a-13. Signature and POA information are present. The filing provides transparent reporting of insider liquidity and estate-planning activity without introducing new governance items.
