Iron Mountain heads into its November 5 earnings report with a calm lending market, easing short interest, and an analyst community that has spent most of 2026 steadily lifting its price targets, yet the stock trades roughly 22% below where the Street thinks it should be.
The positioning picture is about as relaxed as it gets for a REIT of this size. Short interest has fallen nearly 8% over the past week to 2.5% of the free float, a low level by any measure, and well down from the roughly 8.1 million shares borrowed in early October. Availability is extraordinarily wide at 5,559%, meaning the lending pool holds far more shares than the market is currently borrowing. Borrowing costs have ticked up 35% week-on-week to 0.54%, and are up sharply over the past month, but in absolute terms the rate remains negligible for professional shorts. Options traders are slightly less defensive than usual: the put/call ratio of 1.28 is modestly below its 20-day average of 1.42, a shift in direction worth noting given how elevated protection-buying was through September, when the ratio ran above 1.9. That rotation looks more like normalization than conviction either way.
The most interesting tension this week is between where the stock is trading and what analysts have been arguing all year. The mean price target has reached $144, implying around 28% upside from the October 16 close of $112.51. Almost every recent analyst move has been an upgrade or a target raise. Barclays has lifted its Overweight target twice in 2026, most recently to $144 in early September. Truist raised to $155 in August, the most bullish on the Street. Wells Fargo and JPMorgan have both nudged targets higher after quarterly prints. Rothschild initiated with a Buy and a $132 target in late September. Not one firm has cut a rating or lowered a target in this dataset. The analyst recommendation divergence factor scores in the 100th percentile of the ORTEX universe, meaning the Street's directional alignment on IRM is about as uniform as it ever gets. Where the picture is more mixed: the EV/EBIT factor scores in the 19th percentile, flagging that the market is not cheap on an earnings-to-enterprise-value basis, and EPS surprise ranks in the 31st percentile, suggesting the company has not been a consistent beater on the bottom line.
Insider activity adds a layer of nuance. The 90-day net insider position is minus 149,261 shares worth roughly $17.4 million, driven almost entirely by CEO William Meaney, who sold shares across three tranches on October 1 totalling around $4.2 million, alongside a pre-arranged option exercise. The Chief Commercial Officer and the EVP running the data center business also sold on the same date and again in September. All trades carry the 10b5-1 pre-arranged plan flag, so these are scheduled liquidations rather than discretionary calls, and the significance scores on each transaction are low. The pattern reduces but does not eliminate the signal: senior management has been methodically reducing equity exposure even as the analyst community has been methodically lifting targets.
Institutional ownership is concentrated and broadly constructive. BlackRock held 11.3% as of September 30, adding 550,000 shares in the period. Vanguard entities together account for roughly 15.5% of shares, also adding through the quarter. State Street and Dimensional have both been buyers. Cohen & Steers, the specialist REIT manager, trimmed its stake from 6.46% to 4.89% as of its most recent filing in May, a more notable move given its sector focus, though the filing is now several months old.
The data-center REIT peer group has been softer on the week. Close peer DLR slipped 1.6% over seven days, and EQIX fell nearly 4%, leaving IRM's modest 1.7% weekly decline broadly in line with the group. The August earnings print produced a 1-day drop of 2.8% that largely recovered within five days, a pattern that positions the November 5 release as a test of whether that resilience holds, or whether the gap between the mean target and the current price begins to close.
What to watch into the print: whether CEO share sales continue through October, and whether the put/call ratio reverses back toward its September highs as the reporting date approaches.
