Analysis
Iron Mountain reported broad second-quarter growth. Total Revenues were $2,029 million, up 19%, with Storage Rental Revenue of $1,135 million, up 12%, and Service Revenue of $894 million, up 27%. The release states that total reported revenue increased 17.6% excluding foreign currency exchange and that organic revenue growth was 16.8% year over year. Service revenue expanded faster than storage rental revenue, while data center, digital, and ALM growth businesses collectively grew more than 50% year over year.
Profitability improved materially from the prior-year period. Net Income was $106 million versus a Net Loss of $(43) million, which the company attributed primarily to increased Operating Income. Adjusted EBITDA increased to $727 million from $628 million, and Adjusted EPS increased to $0.60 from $0.48. Adjusted EBITDA Margin was 35.8%, compared with 36.7%, a change of -90 bps, despite the reported operating leverage from transformation activities.
Cash-generation measures also increased. AFFO was $433 million, up 17%, and AFFO per share was $1.44, up 16%. FFO (Normalized) per share was $1.01 compared with $0.87. Year-to-date results similarly showed Total Revenues of $3,965 million, Adjusted EBITDA of $1,435 million, and AFFO of $859 million, each above the respective prior-year amounts reported in the release.
Management raised full-year 2026 guidance to $7,940 - $8,010 in Total Revenue, $2,945 - $2,975 in Adjusted EBITDA, $1,760 - $1,780 in AFFO, and $5.87 - $5.93 in AFFO Per Share. Q3 2026 guidance calls for approximately $1,980 in Total Revenue, approximately $745 in Adjusted EBITDA, approximately $440 in AFFO, and approximately $1.47 in AFFO Per Share. The company also highlighted 110 megawatts of data center leasing year to date through July, including 75 megawatts in July.
Capital returns included a third-quarter quarterly cash dividend of $0.864 per share of common stock, payable on October 2, 2026, to shareholders of record on September 15, 2026. The principal reported point of attention is the Adjusted EBITDA Margin decline, while the raised guide, strong service revenue growth, and stated acceleration in data center leasing frame the operational outlook.

Background
This SEC 8-K includes Iron Mountain’s Q2 2026 earnings press release and supplemental financial information (Item 2.02).
Ticker impact

No specific regional shock described; impact is company-specific.
Limited global spillover beyond the data center leasing and enterprise services theme.
Counterpoint
Margin metrics show Adjusted EBITDA margin down year over year (35.8% vs 36.7%), which could temper enthusiasm despite revenue growth.
