Iron Mountain Incorporated (IRM) falls on deep earnings beat
Iron Mountain Incorporated (IRM) beat EPS expectations, but shares fell as investors focused on revenue outlook, valuation, and a softer fourth-quarter guide. This deep-dive examines segment growth, margin expansion, AFFO strength, and why a modest beat wasn’t enough to lift the stock.
Iron Mountain Incorporated (NYSE: IRM) posted a third-quarter EPS beat and matched revenue expectations, but the stock fell 11.49% as investors zeroed in on fourth-quarter revenue guidance that came in below consensus. The quarter still showed strong underlying execution, with data centers and Asset Lifecycle Management driving growth, margins expanding, and full-year guidance raised, but the market is signaling that the bar for IRM is now higher.
Iron Mountain Incorporated (IRM) earnings: stock falls after EPS beat. Iron Mountain delivered third-quarter EPS of $0.64 versus the $0.612 estimate, while revenue matched consensus at $1.99B. Still, IRM falls 11.49% to $105.03 in the Nov. 5 regular session, with volume above its average. The sharp move shows that a small earnings beat carries less weight when investors focus on forward revenue and valuation expectations.
Key Takeaways
EPS reached $0.64 against the $0.612 consensus estimate. Revenue came in at $1.99B, matching estimates.
Data centers led segment growth with revenue up 34% year over year to $274M. Asset Lifecycle Management revenue rose 43% to $241M.
Adjusted EBITDA reached $748M, up 13%, while the adjusted EBITDA margin expanded to 37.6%.
Iron Mountain raised full-year 2026 guidance to $7.95B to $8.02B in revenue and $5.94 to $6.00 in AFFO per share.
The company projects fourth-quarter revenue of about $2.03B, below the $2.05B consensus cited by Investing.com.
CEO William Meaney stressed data center, digital, and ALM growth. CFO Barry Hytinen emphasized record AFFO and operating cash flow.
The analyst consensus remains Buy, with 14 Buy ratings, 2 Holds, and 5 Sells. Public tracking showed no immediate post-earnings upgrade or downgrade.
Financial Performance: Revenue, Margins, and EPS
Iron Mountain generated $1.99B in third-quarter revenue, up $237M from the prior year. Revenue grew 13% on both a reported and organic basis. The result matched the $1.99B consensus estimate, so the quarter's headline beat came from earnings rather than sales.
The quarterly financial series records revenue of $2.03B in the second quarter and $1.94B in the first quarter. Therefore, third-quarter revenue fell below the second-quarter figure but stayed above the first-quarter result. The broader trend remains higher, with prior-quarter revenue listed at $1.84B, $1.75B, and $1.71B.
Global Records and Information Management remained the largest segment. Revenue reached $1.4B, up 7% year over year on both reported and organic measures. Storage revenue rose 5%, while service revenue increased 10% on a reported basis and 9% organically. The segment produced a record $630M of adjusted EBITDA, equal to a 44% margin.
Global Data Center revenue rose 34% to $274M. Lease commencements and strong pricing drove the gain. Iron Mountain commenced 58 leases totaling 29 megawatts during the quarter. The company also renewed 168 leases totaling 9 megawatts, with pricing spreads of 10% on a cash basis and 15% on a GAAP basis. Data Center adjusted EBITDA reached $154M, producing a 56.3% margin.
ALM revenue rose 43% to $241M, or 38% organically. Enterprise ALM grew more than 50% organically, according to CFO Barry Hytinen. Data center decommissioning posted low double-digit growth, despite a $30M revenue shift discussed in August. After adjusting for that shift, management said decommissioning growth exceeded 50%.
Profitability also improved. Adjusted EBITDA increased $88M to $748M, and the margin expanded by nearly 200 basis points sequentially. AFFO reached $458M, up 17% year over year. AFFO per share rose 16% to $1.53, a new record. Year-to-date operating cash flow reached $1.2B, up $364M, while free cash flow improved by nearly $400M.
The earnings-surprise history also shows four straight quarters with actual EPS above estimates. That record gives the $0.64 result credibility, even though the market reaction focused on the outlook rather than the quarter alone.
Market Reaction and Analyst Response to IRM Earnings
At 2:30 p.m. ET on Nov. 5, IRM traded at $105.03, down 11.49%. Trading volume reached 2,168,477 shares against an average of 1,495,950. The move was therefore substantial in both price and participation.
The reaction looks especially severe beside the operating results. EPS beat estimates, adjusted EBITDA grew 13%, AFFO grew 17%, and full-year guidance increased. However, the fourth-quarter revenue target of about $2.03B sits below the $2.05B consensus cited by . That gap gives short-term sellers a clear point of focus.
The broader analyst view remains positive. The current consensus lists 14 Buy ratings, 2 Holds, and 5 Sells. Before the earnings date, visible bullish actions included Rothschild & Co initiating coverage at Buy with a $132 target on Sept. 21. Barclays raised its target from $143 to $144, Truist lifted its target from $140 to $155, Wells Fargo moved from $135 to $140, and J.P. Morgan raised its target from $121 to $138.
Benzinga's pre-earnings tracker showed an average price target of $126.17, based on 10 Buy ratings and 1 Sell rating. The target actions point to a strong prior bullish setup. As a result, the earnings beat had to clear a high bar. The absence of immediate post-earnings downgrades supports the view that analysts have not broadly abandoned the growth thesis.

CEO William Meaney framed Iron Mountain as a growth platform with a recurring records business underneath it. He said growth businesses will represent more than one-third of total revenue in 2026. He also said those businesses will contribute 11 of the 16 percentage points of projected consolidated growth.
"These high-growth businesses have continued to exceed our targets and represent an increasingly large portion of our total revenue as well as our total addressable market of $170 billion." - William Meaney, CEO, Earnings Call
Meaney's strategic case rests on several engines. Data center leasing reached 102 megawatts in the quarter and 137 megawatts year to date. The company added a second new hyperscale relationship in 2026 and signed 74 megawatts in India. It also expects about 325 megawatts of leasable capacity to energize within 24 months.
"Revenue increased 13% on both a reported and an organic basis, and adjusted EBITDA and AFFO grew 13% and 17%, respectively." - William Meaney, CEO, Earnings Call
CFO Barry Hytinen supplied the financial detail behind that narrative. He highlighted the $748M adjusted EBITDA result, the sequential margin expansion, and record AFFO per share. He also provided the clearest segment outlook, with ALM revenue now projected to finish modestly above $1B for the full year.
"Based on our continued strong growth, we now project ALM revenue to be modestly ahead of $1 billion for the full year." - Barry Hytinen, CFO, Earnings Call
Hytinen also explained why cash generation improved. Matterhorn restructuring costs totaled $152M during the first nine months of 2025 and $0 during the comparable period of 2026. That change, along with business growth and a better cash conversion cycle, drove the year-to-date cash flow improvement.
"This marks the best year-to-date operating cash flow the company has ever achieved." - Barry Hytinen, CFO, Earnings Call
Iron Mountain's third quarter combined an EPS beat, record AFFO, stronger margins, and raised full-year guidance. Yet the 11.49% decline shows that the stock had already priced in much of the growth story, while the softer fourth-quarter revenue target created a near-term pressure point.The investment case still rests on data center leasing, ALM expansion, digital solutions, and durable records cash flow. Execution on the 325-megawatt capacity pipeline and the $1B-plus ALM target will shape whether IRM can turn its strong operating results into renewed share-price momentum.
