Iron Mountain to Post Q2 Earnings: What's in the Cards for the Stock?

Iron Mountain (IRM) is forecast to report Q2 2025 revenue growth of 9.3% to $1.68 billion and increased adjusted funds from operations (AFFO) per share, driven by robust data center leasing and a diversified revenue base. Despite these positive trends, the REIT faces headwinds from an estimated 9.4% rise in interest expenses and shifts in physical storage demand. The Zacks consensus estimate for AFFO per share is $1.19, though the quantitative model does not predict an earnings surprise, indicating current expectations are largely priced into the stock.

Analysis

Iron Mountain (IRM) is approaching its second-quarter 2025 earnings release with expectations of robust top-line growth contrasted by significant bottom-line pressures. Consensus estimates project a 9.3% year-over-year increase in total revenues to $1.68 billion, driven by strong performance across all key segments. The global data center business is a notable catalyst, with expected revenue of $189.7 million, up from $152.7 million in the prior-year period, fueled by high demand for connectivity and colocation. However, this growth narrative is tempered by considerable headwinds, primarily a projected 9.4% year-over-year rise in interest expenses, which is expected to weigh on profitability. This is compounded by high SG&A costs from international expansion and the secular decline in physical record storage. While the consensus Adjusted Funds From Operations (AFFO) estimate of $1.19 per share represents year-over-year growth, analyst confidence has slightly waned, as reflected by a one-cent downward revision over the past three months. Critically, the Zacks quantitative model does not predict an earnings surprise, citing a neutral 0.00% Earnings ESP and a Zacks Rank #3 (Hold), suggesting that current market expectations are likely aligned with the forthcoming results.

Key Decisions for Investors

• Investors should weigh the company's strong projected revenue growth, particularly from the high-demand data center segment, against the significant margin pressure from an estimated 9.4% rise in interest expenses.
• Given the quantitative model's prediction of no earnings surprise and the recent downward revision in the AFFO consensus, it may be prudent to anticipate that the stock's performance will align closely with current estimates, potentially limiting the catalyst for a post-earnings rally.
• Upon the earnings release, focus on management's guidance regarding the trajectory of interest expenses and data center leasing momentum, as these are the primary opposing factors shaping the company's near-term profitability.
• Note the contrast with peers like PLYM and COLD, for which the same quantitative model indicates a higher probability of an earnings beat, a factor to consider when allocating capital within the REIT sector.
