IRON MOUNTAIN INC 8-K

What Happened
Iron Mountain Incorporated announced on June 26, 2026 that it completed a private offering of $1,500,000,000 aggregate principal amount of 6.250% Senior Notes due January 15, 2035. The Notes were sold at par and were issued under an indenture dated June 26, 2026; interest accrues from June 26, 2026 and is payable semi‑annually on January 15 and July 15 (first payment January 15, 2027). The company intends to use the roughly $1,481.8 million of net proceeds to repay all or part of outstanding borrowings under its revolving credit facility and to pay related fees and expenses, with any remainder for general corporate purposes.

Key Details

• Offering size and price: $1.50 billion of 6.250% Senior Notes, sold at 100.00% of par; net proceeds ≈ $1,481.8 million.
• Maturity and payments: Matures January 15, 2035; interest 6.250% per year, paid semi‑annually (Jan 15 / Jul 15).
• Security and ranking: Unsecured senior obligations, initially jointly and severally guaranteed by U.S. subsidiaries that cover the substantial majority of U.S. operations; pari passu with other senior debt, senior to subordinated debt, but effectively subordinated to secured debt and structurally subordinated to non‑guarantor subsidiaries.
• Offering mechanics and protections: Sold in a private placement to qualified institutional buyers (Rule 144A) and non‑U.S. persons (Reg S); includes customary redemption features (make‑whole prior to July 15, 2029; specified redemptions thereafter), change‑of‑control repurchase provisions, events of default and customary restrictive covenants (e.g., limits on liens and sale‑leaseback transactions).

Why It Matters
This filing creates a new, long‑dated senior unsecured debt obligation for Iron Mountain and is a source of liquidity used primarily to reduce short‑term borrowings under its revolver. For investors, the key takeaways are the interest cost (6.25%), the long maturity (2035), and the notes’ unsecured status and subordination to secured creditors—factors that affect credit risk and priority in a downside scenario. The private placement limits immediate market liquidity for the notes (sold to QIBs and non‑U.S. investors), and the indenture’s covenants and redemption terms define the company’s flexibility to manage this debt.
