About
Iron Mountain Incorporated is a global storage and information management services company that has evolved from a physical records storage business into a hybrid physical-and-digital infrastructure REIT, founded in 1951 by Herman Knaust in an abandoned iron ore mine in Livingston, New York, and now headquartered in Boston, Massachusetts, trading on NYSE (IRM). The company generated approximately $6.1 billion in revenues for FY2024 under CEO William Meaney, managing over 1,450 facilities across 60+ countries. Iron Mountain's physical Records Management segment—storing approximately 750 million cubic feet of physical records in its vast warehouse network and providing secure document destruction through Recall and SFG subsidiaries—generates highly predictable, recurring storage rental revenues from long-term contracts with corporations, healthcare providers, government agencies, and financial institutions obligated by regulatory retention requirements to preserve documents for decades.

About
Public Storage is a Glendale, California-based self-storage real estate investment trust — publicly traded on the New York Stock Exchange (NYSE: PSA) as an S&P 500 Real Estate component — owning and operating approximately 3,300 self-storage facilities containing 240+ million net rentable square feet across the United States, and holding an equity interest in Shurgard Self Storage (EURONEXT: SHUR) — Europe's largest self-storage operator — through approximately 5,000 employees. Public Storage is the largest self-storage company in the world by square footage and market capitalization, founded in 1972 by Wayne Hughes and B. Wayne Hughes Jr., maintaining leadership through continuous facility acquisitions and development across high-demand storage markets (California, Florida, Texas, New York, Chicago). In fiscal year 2024, Public Storage reported revenues of approximately $4.1 billion and same-store net operating income declining slightly as new self-storage supply (record self-storage construction from 2021-2023 starts) competed with Public Storage's existing portfolio for customers, creating the storage supply cycle headwind that follows periods of elevated construction activity. CEO Joe Russell's capital allocation strategy in 2024 included the acquisition of Simply Self Storage ($2.2 billion from Blackstone Real Estate — adding 127 properties primarily in Southeast and Midwest markets) and the ongoing development pipeline of new Public Storage facilities in high-barrier-to-entry urban and first-ring suburban markets where land scarcity limits new competition. Public Storage's brand (the orange cube — instantly recognizable logo with over 50 years of consumer awareness) and digital marketing dominance (PS.com as the #1 self-storage website by traffic) drive customer acquisition at lower cost than smaller operators competing with Public Storage for the same storage customer.
