Iron Mountain Marks Fifth Consecutive Year of Record Highs Propelled by Data Center Expansion

Iron Mountain Inc (NYSE:IRM) unveiled fourth-quarter financial results that significantly exceeded Wall Street forecasts, underscoring the company’s resilience and the surging demand for data infrastructure. The company reported adjusted earnings per share of $0.61, climbing from $0.50 in the prior year and surpassing the $0.59 consensus estimate. More impressively, adjusted funds from operations (AFFO) per share jumped to $1.44 from $1.24 year-over-year, while total revenue reached $1.843 billion against a projected $1.803 billion.

This marks the fifth consecutive year that Iron Mountain has delivered all-time highs across revenue, adjusted EBITDA, and AFFO—a testament to the company’s strategic positioning in the booming data center sector. The company’s adjusted EBITDA margin remained stable at 38.3%, with operating income hitting $341.04 million.

Diversified Revenue Streams Power Growth Trajectory

Iron Mountain’s revenue expansion reflects strength across multiple business lines. Storage rental revenue surged 13% to $1.06 billion, while service revenue accelerated 22% to $782 million, demonstrating robust demand for both traditional records management and value-added services.

By business segment, Global Records and Information Management (RIM) revenue climbed to $1.37 billion from $1.26 billion. However, the standout performer was the Global Data Center segment, which jumped to $237 million from $170 million—a 39% year-over-year surge that signals extraordinary momentum in the company’s highest-growth business. Corporate and Other revenue increased to $234 million from $153 million.

Data Center Capacity Expansion and Dividend Signal Confidence

The company declared a quarterly cash dividend of $0.86 per share for the first quarter, reinforcing management’s confidence in sustained cash generation. CEO William L. Meaney emphasized that Iron Mountain’s performance reflects the macro tailwinds propelling data center demand globally. The company enters 2026 with 400 megawatts of new data center capacity scheduled to come online over the next 24 months, positioning it to capture incremental leasing opportunities in an increasingly capacity-constrained market.

Guidance Points to Double-Digit Growth in 2026

Iron Mountain provided forward guidance that outpaces analyst consensus. For fiscal 2026, the company expects revenue between $7.625 billion and $7.775 billion, compared to the $7.596 billion analyst estimate, and AFFO per share of $5.69 to $5.79 versus the consensus of $4.22. For the first quarter specifically, management projects revenue of $1.86 billion (against the $1.797 billion forecast) and AFFO per share of $1.39 (aligned with the $1.40 estimate).

The divergence between Iron Mountain’s outlook and Wall Street expectations highlights management’s confidence in accelerating data center leasing dynamics and continued expansion in its recurring records storage base. This positions the company to sustain double-digit revenue and profit growth throughout 2026.

Market Reaction Validates Strategic Positioning

Iron Mountain shares surged approximately 9% to $109 on Thursday, reflecting market enthusiasm for the company’s growth trajectory and the structural tailwinds supporting data infrastructure demand. With significant capacity coming online and management guiding above consensus, Iron Mountain appears well-positioned to extend its streak of record-breaking years into the foreseeable future.
