Iron Mountain (IRM) Earnings Date & Reports

Key Takeaways

• Iron Mountain (IRM) reports third quarter 2026 results on Thursday, November 5, 2026, before the market opens.
• Consensus estimates call for earnings of approximately $0.61 per share on revenue of roughly $1.99 billion.
• The company has beaten consensus earnings per share (EPS) estimates in five of its last eight quarters.
• Investors are focused on momentum in data centers, asset lifecycle management (ALM), and digital services, which now represent about 35% of total revenue.
• Full-year 2026 guidance was raised in August, adding pressure on the company to confirm that outlook this quarter.

Earnings Context and Why It Matters

Iron Mountain, historically known for physical records storage, has repositioned itself as a fast-growing digital and data infrastructure company. Its higher-growth segments — data centers, ALM, and digital solutions — grew more than 50% combined in recent quarters and are reshaping the revenue mix. This makes the quarterly report a key checkpoint for investors assessing whether that transformation remains on track. With full-year guidance raised in August and a premium valuation relative to peers, the upcoming print will test whether the company's growth narrative can keep pace with elevated market expectations.

Earnings Expectations

Analysts expect Iron Mountain to report earnings of about $0.61 per share on revenue of roughly $1.99 billion for the third quarter of 2026. A year earlier, the company posted EPS of $0.54 on revenue of $1.80 billion, implying healthy year-over-year growth on the top line.

The company's most recent report offers useful context. In the second quarter, Iron Mountain delivered EPS of $0.60, beating the consensus estimate of roughly $0.54, while revenue of $2.03 billion came in above the $1.97 billion Wall Street was modeling. Management also issued third-quarter revenue guidance of about $1.98 billion and raised its full-year outlook to revenue of $7.94 billion to $8.01 billion.

Beyond headline figures, investors will be watching several company-specific metrics. Because Iron Mountain operates as a real estate investment trust (REIT), funds from operations (FFO) and adjusted funds from operations (AFFO) — measures that add back non-cash charges like depreciation to reflect recurring cash earnings — matter more than traditional EPS. Adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization) and data center leasing activity, measured in megawatts, will also draw close attention.

Market Reaction and Investor Sentiment

Sentiment heading into the print is cautiously optimistic but reflects the stock's elevated valuation. Iron Mountain shares have pulled back from earlier 2026 highs even as the company has consistently topped estimates, a sign that some investors have been locking in gains after a strong multi-year run. The stock has shown notable sensitivity around earnings, making the November report a potential catalyst in either direction.

Key risk factors heading into the release include the pace of data center leasing, margin trends as the revenue mix shifts toward capital-intensive businesses, and whether the company reaffirms its raised full-year guidance. Any sign of slowing growth in the data center segment or softer-than-expected AFFO could weigh on the stock given how much of the current narrative is tied to that business.

Forward Outlook and Key Factors to Monitor

Following this report, investors should focus on the trajectory of Iron Mountain's growth segments and the durability of its guidance. Data center demand remains the central theme, with leasing activity and pre-leasing rates serving as leading indicators of future revenue. Management's commentary on power availability, construction timelines, and customer demand will be closely parsed.

Margin performance also warrants attention. As data centers and ALM grow as a share of the business, the company's cost structure and capital expenditures will shape both adjusted EBITDA margins and AFFO growth. Investors will want to see that top-line acceleration is translating into cash earnings rather than simply absorbing higher costs.

Finally, watch the balance sheet. Iron Mountain reduced net lease-adjusted leverage to about 4.8x in recent quarters, its lowest level since converting to a REIT structure in 2014. Sustaining that discipline while funding data center expansion will be important for investor confidence. Combined, these factors will determine whether the company can maintain the momentum that has supported its stock through 2026.
