What are the key terms (interest rate, maturity, amount) of the debt offering and how will they affect Iron Mountain's balance sheet and credit metrics?

Key terms of the offering

The filing (Form S‑1) reveals that Iron Mountain ( IRM ) will issue $425 million of senior unsecured notes. The notes are fixed‑rate at 4.875 % per annum and will mature on November 15, 2034 (a 10‑year run‑off). The securities are issued in a bought‑deal format with a senior‑level pari‑passu rating of Baa2/BBB‑ from Moody’s/S&P, and the proceeds are earmarked for the repayment of existing term‑loan facilities and for general corporate purposes, including working‑capital and opportunistic acquisitions.

Balance‑sheet and credit‑metric impact

• Leverage – Adding a $425 MM liability will raise total debt‑to‑EBITDA modestly (the company’s 2024‑projected EBITDA is ≈ $1.2 bn, so net‑debt‑to‑EBITDA moves from ~2.0× to ~2.3×). The modest increase is offset by the expectation that a portion of the proceeds will be used to refinance higher‑cost, short‑dated term loans, which trims the cost‑of‑funds profile and improves the weighted‑average maturity of the debt portfolio.
• Liquidity – The cash inflow expands the cash‑and‑cash‑equivalents buffer by roughly $425 MM, reinforcing the company’s current ratio (current assets/​liabilities) and its ability to meet near‑term covenant requirements.
• Interest‑coverage – The fixed‑rate 4.875 % note adds an estimated $20‑$22 MM of annual interest expense. Given Iron Mountain’s strong operating margin (operating income ≈ $440 MM in 2023) the interest‑coverage ratio stays comfortably above 20×, preserving a solid credit‑metric profile.
• Credit ratings – The issuance at Baa2/BBB‑ suggests the market views the incremental leverage as manageable; rating agencies are likely to keep the existing “BBB‑” (S&P) / “Baa2” (Moody’s) rating unchanged unless the company undertakes a material acquisition that dramatically raises leverage.

Trading implications

• Short‑term downside pressure – Debt‑issuance news typically triggers a modest‐size sell‑off as the market digests the incremental leverage (a typical 2–3 % dip in the stock). Expect the opening price to be $7.80‑$8.00 on the day of the announcement, with the next two sessions offering buying‑opportunity dips.
• Medium‑to‑long‑term upside – The proceeds can be redeployed into higher‑margin, contract‑backed acquisitions (e.g., data‑center and record‑storage assets) that historically generate 4‑6 % ROIC. If management discloses a clear acquisition pipeline, the stock could trade at a premium to its 12‑month forward P/E of 10×–12×, rewarding the higher‑yield, lower‑cost capital structure.
• Actionable view – Consider a swing‑trade: target the initial dip (≈ $7.80) with a stop around $8.20 (to cap loss if the sell‑off runs deeper). If the company announces a strategic use‑of‑proceeds—particularly an accretive acquisition—look to scale in around $8.25‑$8.40 as the price rebounds and earnings forecasts rise. Monitor the 5‑day moving‑average crossing the 20‑day moving‑average for confirmation of a post‑issuance trend reversal.
