Insider sale adds nuance to strong share performance

As of September 18, 2026, Iron Mountain shares had climbed from USD 83.05 at the start of 2026 to about USD 114.30, an increase of approximately 37.6% that significantly outpaces the broader S&P 500 benchmark over the same period according to MarketBeat.

A notable development for investors is a recent insider transaction: Mark Kidd, EVP and GM Data Centers and ALM at Iron Mountain, sold 6,000 shares of common stock at a weighted-average price of USD 115.60 per share on September 1, 2026, under a Rule 10b5-1 trading plan, realizing a transaction value of around USD 694,000 according to a Form 4 summary reported by The Globe and Mail.

Following this sale, Mark Kidd continues to hold 95,507 Iron Mountain shares directly, corresponding to a post-transaction market value of roughly USD 10.9 million based on the September 1, 2026 closing price of USD 114.22 reported in the same company snapshot, indicating that the sale represented only about 6% of his direct equity position.

Dividend and fundamental context support the investment case

Iron Mountain combines its share-price strength with a regular income component. According to a recent overview from MarketBeat, the company declared a quarterly dividend of USD 0.864 per share for stockholders of record on September 15, 2026, with the ex-dividend date also on September 15, 2026, and a forward annualized dividend indicated at about USD 3.46 per share.

From a fundamental standpoint, Iron Mountain’s trailing twelve-month revenue stands at approximately USD 7.6 billion and net income at around USD 435.5 million, according to the company snapshot cited by The Globe and Mail, underscoring the scale and profitability supporting its real estate investment trust structure.

The same snapshot puts Iron Mountain’s market capitalization at about USD 34.0 billion as of early September 2026, a figure broadly in line with the USD 34.03 billion market cap reported for September 2026 by CompaniesMarketCap, which notes that the company’s market value has increased by roughly 40.45% in 2026.

Analyst targets and trading metrics frame current valuation

Recent institutional flows also highlight confidence in the stock.
