What this transaction means for investors
This sale shouldn’t concern investors. It was executed under a Rule 10b5-1 plan that insiders commonly use to execute pre-planned transactions for personal financial management purposes, avoiding concerns about acting on non-public information.
Moreover, the executive retained a large stake of more than 95,000 shares in the company’s stock.
Importantly, Iron Mountain continues to expand. TTM revenue grew 17% year over year to $7.6 billion. Its operating profit grew 35%, reaching $1.4 billion, demonstrating a highly profitable business model.
However, the stock may need to cool off before heading higher. The strong run over the past few years has lifted its valuation to expensive levels on a price-to-earnings basis. Analysts are only expecting earnings to grow at an annualized rate of 12% in the coming years. Overall, Iron Mountain is solidly positioned to continue benefiting from growing demand for its physical storage business.
