Iron Mountain (IRM) Financials

Iron Mountain’s latest statements show a business that has expanded substantially since 2023, with stronger revenue, operating income and operating cash flow. However, that growth has been accompanied by higher capital spending, a larger debt load and persistently negative common equity.

• Revenue growth remains strong. Q2 2026 revenue reached $2.03 billion, up from $1.36 billion in Q2 2023 and $1.71 billion in Q2 2025. This represents approximately 49% growth over three years and 18% growth year over year.
• Operating profitability has improved. Operating income increased to $373.5 million in Q2 2026 from $212.5 million in Q2 2023. The operating margin improved to approximately 18.4% from 15.6%, helped by revenue growth and lower selling, general and administrative costs as a percentage of sales.
• Operating cash flow has strengthened. Q2 2026 operating cash flow was $549.3 million, compared with $375.1 million in Q2 2025, $382.2 million in Q2 2024 and $317.3 million in Q2 2023. This provides meaningful internal funding for dividends, debt service and investment.
• Reported earnings have recovered from the prior-year loss. Restated Q2 2025 results showed a $43.3 million net loss, or a $0.15 loss per share. Q2 2026 produced $106.1 million of net income and $0.34 of diluted earnings per share. Restructuring expense also fell to zero in both Q1 and Q2 2026, compared with substantial charges throughout 2024 and 2025.
• The company continues to invest in its asset base. Net property, plant and equipment increased to $10.27 billion in Q2 2026 from $5.60 billion in Q2 2023. This investment may support future storage, data center and information-management revenue, although it requires significant upfront cash.
• Cash generation is heavily offset by capital expenditures. Q2 2026 capital expenditures were $588.2 million, versus $556.8 million in Q2 2025 and $334.9 million in Q2 2023. Operating cash flow less capital expenditures was approximately negative $38.9 million in Q2 2026. The gap has narrowed from roughly negative $181.6 million in Q2 2025, but the company is not consistently producing positive quarterly free cash flow after capital spending.
• Working-capital needs are increasing. Accounts receivable reached $1.49 billion in Q2 2026, up from $1.18 billion in Q2 2023. The increase is consistent with the company’s larger revenue base, but investors should monitor collections and cash conversion as the receivables balance grows.
• Leverage remains the primary financial risk. Short- and long-term debt totaled approximately $17.35 billion in Q2 2026, up from about $11.55 billion in Q2 2023. Cash interest paid reached $119.7 million in Q2 2026, compared with $65.2 million in Q2 2023, increasing the pressure on cash flow.
• Financing activity shows continued dependence on refinancing. Q1 and Q2 2026 included multi-billion-dollar debt issuances and repayments. Although this may reflect refinancing rather than equivalent net borrowing, it highlights the company’s exposure to credit-market conditions and interest rates.
• Common equity remains negative. Total common equity was negative $1.28 billion at June 30, 2026, compared with negative $767.4 million at June 30, 2025 and positive $211.6 million at year-end 2023. Total liabilities of $22.85 billion also exceeded total assets of $21.96 billion, leaving limited balance-sheet equity protection for common shareholders.

Overall, Iron Mountain’s operating performance is moving in a favorable direction: revenue and operating cash flow are growing, margins have improved and recent earnings have returned to positive territory. The main offset is the company’s capital-intensive and highly leveraged financial structure. For investors, the key indicators to watch are sustained free cash flow after capital expenditures, debt reduction, interest costs and whether growing revenue can continue without further deterioration in common equity.
