Item 2 of the 10-K filed Feb 12, 2026.16

The story

Founding and early years (1951–1970)

The company was started by Herman Knaust, who had made his fortune growing and marketing mushrooms. He purchased a depleted iron ore mine and 100 acres (0.40 km2) of land in Kingston, New York, for $9,000 in 1936. By 1950, the mushroom market had shifted, and Knaust was looking for alternative uses for his mine, which he had named "Iron Mountain." Knaust saw a business opportunity amidst widespread Cold War fears to protect corporate information from nuclear attack and other disasters.

The company was originally founded in 1951 as Iron Mountain Atomic Storage Corporation; it opened its first underground "vaults" in 1951 and its first sales office in the Empire State Building, about 125 miles (201 km) south. Iron Mountain's first customer was East River Savings Bank, which brought microfilm copies of deposit records and duplicate signature cards in armored cars for storage in the mountain facility.

Middle years (1970–2000)

This first iteration of Iron Mountain was bankrupt by the early 1970s and was wholly acquired by Vincent J. Ryan through his holdings in Schooner Capital Corporation, Boston, Massachusetts. At the time, it consisted of the original facility in Livingston, New York and IMAR (Iron Mountain at Rosendale), a former limestone mine and mushroom cave outside of Kingston, New York.

In 1978, the company opened its first above-ground records-storage facility. In 1980, it expanded to Rhode Island through the purchase of a former Industrial National Bank (a precursor to FleetBoston) cold site and data tape repository in Glocester, Rhode Island. It had many Fortune 500 clients at the time, and its revenue was in the $6 million range in the early 1980s.

In the mid-1980s, it convinced Manufacturers Hanover Bank to move all its paper records out of Manhattan to an above-ground facility, a former strip mall in Port Ewen, New York. This was the first time a records management company used barcodes to enable real-time access to shipped boxes and the documents inside.

During the 1980s, the company expanded beyond New York, opening facilities throughout New York and New England, and in 1988, extended its reach into 12 more U.S. markets by acquiring Bell & Howell Records Management, Inc. The firm went public on January 31, 1996. In 1997, Iron Mountain became a leading software escrow company with the acquisition of Data Securities International (DSI). In 1998, Iron Mountain made its first overseas acquisition by buying British Data Management, Ltd. The company reported a $423 million revenues by the end of the same fiscal year of its acquisition.

Expansion and consolidation (2000–present)

In February 2000, Iron Mountain Incorporated announced the completion of its acquisition of Pierce Leahy Corp. (NYSE:PLH) in a stock-for-stock merger valued at approximately $1.1 billion. In 2004, Iron Mountain formed a digital assets division called "Iron Mountain Digital", following the acquisition of Connected Corporation, a maker of online PC backup software. In 2005, Iron Mountain Digital bought LiveVault, a provider of online backup software for server data. In 2007 Iron Mountain acquired Stratify Inc., one of the larger e-discovery service providers at the production end of the Electronic Discovery Reference Model (EDRM). The acquired businesses of LiveVault and Stratify Inc. were consolidated into Iron Mountain Digital. In 1981, Richard Reese became the company's CEO. In 1995, he concurrently assumed the position of chairman. He remained as CEO until June 2008, when he was replaced by Bob Brennan, but he remained in the chairman's seat. In April 2011, the company announced Brennan's departure, and Reese resumed his former title.

In February 2010, Iron Mountain acquired California-based eDiscovery and content archiving software provider, Mimosa Systems. The acquisition, too, was absorbed into Iron Mountain Digital. In May 2011, Iron Mountain divested Iron Mountain Digital, which was acquired by the British enterprise search and knowledge management firm Autonomy Corporation for $380 million. In August 2011, Hewlett-Packard acquired the Cambridge-based Autonomy, and amalgamated the operations of Autonomy (which included Iron Mountain Digital) into HP's enterprise software division. In May 2012, Iron Mountain expanded its high-security storage facility business through the acquisition of three records storage firms—File House Offsite Record Storage in Fredericksburg, Virginia; and Document Systems Inc. in Columbia, South Carolina; and First National Safe Deposit in Philadelphia. In November 2013, Iron Mountain announced it would be shutting down its Saint John, New Brunswick, contact center in 2014.

As of January 1, 2014, Iron Mountain successfully converted to a real estate investment trust after approval of private letter ruling requests by the IRS to classify steel racking structures as qualified real estate assets.

At the end of April 2015, Iron Mountain announced it would acquire Australian data protection services provider Recall Holdings for around $2.2 billion in cash and stock. At the end of March 2016, the Australian Competition & Consumer Commission released a statement saying it would not block the acquisition of Recall pursuant to Iron Mountain's agreement to divest most of its Australian business. At the same time, the Canadian Competition Bureau announced it entered an agreement with Iron Mountain to allow the acquisition as long as Iron Mountain divested records management assets in the markets in which it found the acquisition would limit effective remaining competitors: Toronto, Montreal, Ottawa, Calgary, Edmonton and Vancouver.

The US Department of Justice agreed to allow the acquisition, provided that Iron Mountain divested records management assets in the 15 markets where Iron Mountain and Recall were two of the top three competitors. These markets include Detroit; Kansas City, Missouri; Charlotte, North Carolina; Durham, North Carolina; Raleigh, North Carolina; Buffalo, New York; Tulsa, Oklahoma; Pittsburgh; Greenville/Spartanburg, South Carolina; Nashville, Tennessee; San Antonio, Texas; Richmond, Virginia; San Diego; Atlanta; and Seattle.

The UK's Competition and Markets Authority approved the acquisition pending an investigation into the acquisition's effect on competition in the UK. In June 2016, the Competition and Markets Authority determined the acquisition would create a "substantial lessening of competition" in Aberdeen and Dundee. In response to this report, Iron Mountain and the Competition and Markets Authority reached an agreement whereby Iron Mountain would sell Recall's existing operations in Aberdeen and Dundee (known as C21 Data Services). On May 2, 2016, Iron Mountain announced the completion of the $2 billion (US) merger, mostly in stock.

In 2016, Fortune magazine listed Iron Mountain at number 729 on its list of the largest 1000 public companies in the United States. In September 2016, the unpublished recordings of musician Prince, consisting of over $200 million worth of recorded music and film, were moved to an Iron Mountain facility in Los Angeles, due to water damage and poor storage conditions in Prince's Paisley Park recording facility, in Chanhassen, Minnesota. In December 2017, the company purchased IO Data Centers' US division for $1.3 billion, which includes four colocation data centers in New Jersey, Ohio and two in Arizona. In February 2021, the company purchased Infofort, an information management solutions provider in the Middle East, North Africa and Turkey (MENAT) region. As of 2023, Iron Mountain's headquarters are located in Portsmouth, New Hampshire. In 2024, Iron Mountain acquired IT asset disposition (ITAD) services provider Regency Technologies for $200 million.

Products and brands

Iron Mountain has underground storage facilities in the United States and the rest of the world, but most of the company's over 1,500 storage locations are in above-ground leased warehouse space located near customers. Its storage location in Dighton, Massachusetts was once a missile storage battery during the Cold War.

The best-known Iron Mountain storage facility is a 1.7 million sq. ft. high-security storage facility in a former limestone quarry at Boyers, Pennsylvania, near the city of Butler in the United States (41.093°N 79.911°W / 41.093; -79.911). The facility features climate controlled storage areas protected by armed guards. It began storing records in 1954 and was purchased by Iron Mountain in 1998. It is here that Bill Gates stores his Corbis photographic collection in a refrigerated cave 220 feet (67 m) underground, as well as where Universal Music Group stores its United States masters.

Nearby, the U.S. Office of Personnel Management leases another cavern to store, and process government employee retirement papers. Appearing at an event in the Oval Office alongside President Donald Trump in February 2025, Elon Musk criticized the OPM's use of this facility. In a Special Report episode Musk and his team ridiculed "the mine," insinuating it was the bottleneck limiting the number of retirement applications that could be processed. The factual accuracy of some aspects of Musk's account have been disputed by journalists and former government employees, although the Government Accountability Office noted problems with the OPM's handling of paperwork in 2019.

The company stores the wills of Princess Diana, Charles Dickens, and Charles Darwin. It also houses the original recordings of Frank Sinatra, as well as master recordings from Sony Music Entertainment (over a million recordings; reportedly in Rosendale, New York), Universal Music Group (in Butler), and Warner Music Group (in southern California). In order to protect the masters, Iron Mountain equips some of its music-holding facilities with professional studios so the masters never have to leave the premises. Over 1,800 cans of unclaimed nitrate film formerly held by Iron Mountain now make up the Iron Mountain Collection at the Academy Film Archive.

Risk factors and legal proceedings

The risks Iron Mountain Incorporated names in Item 1A of its 10-K filed Feb 12, 2026: 39 risks under these headings, as written.16

  • BUSINESS RISKS
  • Failure to execute our strategic growth plan may adversely impact our financial condition and results of operations.
  • As stored records and tapes become less active, our service revenue growth and profits from related services may decline.
  • Our customers continue to evolve the way they store records, which could impact our storage revenue.
  • We and our customers are subject to laws and governmental regulations, including laws relating to data privacy and cybersecurity, and our customers’ demands in this area are increasing. This may cause us to incur significant expenses and non-compliance with such regulations and demands could harm our business.
  • Attacks on our internal IT systems could damage our reputation, cause us to lose revenues and adversely affect our business, financial condition and results of operations.
  • The development and use of AI in our business and operations presents risks and challenges that may adversely impact our business and operating results.
  • Failure to successfully integrate acquired businesses could negatively impact our balance sheet and results of operations.
  • Our future growth depends in part upon our ability to continue to effectively manage and execute on revenue management.
  • Our customer contracts do not always limit our liability and sometimes contain terms that could subject us to significant liability or lead to disputes in contract interpretation.
  • As a global company, we are subject to the unique risks of operating in many countries.
  • If we fail to transition to more sustainable sources of energy, it may negatively impact our ability to attract and retain certain of our customers, employees and investors. Furthermore, changes to environmental laws and standards may increase the cost to operate some of our businesses. This could impact our results of operations, our competitiveness and the trading value of our stock.
The other 28 risks
  • Our use of joint ventures or other co-investment vehicles could expose us to additional risks and liabilities, including our lack of sole decision-making authority and our reliance on joint venture or other co-investment vehicle partners who may have economic and business interests that are inconsistent with our business interests.
  • Significant costs or disruptions at our data centers could adversely affect our business, financial condition and results of operations.
  • We face additional risks in expanding our Global Data Center Business, including the significant amount of capital required.
  • Our ALM business may be subject to additional risks, including those related to its client and geographic concentration, government trade policies, and macroeconomic conditions.
  • Failure to comply with certain regulatory and contractual requirements under our government contracts could adversely affect our revenues, operating results and financial position and reputation.
  • We may be subject to certain costs and potential liabilities associated with the real estate required for our business.
  • Unexpected events, including those resulting from climate change or geopolitical events, could disrupt our operations and adversely affect our reputation and results of operations.
  • Fluctuations in commodity prices may affect our operating revenues and results of operations.
  • Failure to manage and adequately implement our new IT systems could negatively affect our business.
  • RISKS RELATED TO OUR INDEBTEDNESS
  • Our indebtedness could adversely affect our financial health and prevent us from fulfilling our obligations under our various debt instruments.
  • Restrictive debt covenants may limit our ability to pursue our growth strategy.
  • We may not have the ability to raise the funds necessary to finance the repurchase of outstanding senior notes upon a change of control event as required by our indentures.
  • IMI is a holding company, and, therefore, its ability to make payments on its various debt obligations depends in large part on the operations of its subsidiaries.
  • RISKS RELATED TO OUR TAXATION AS A REIT
  • If we fail to remain qualified for taxation as a REIT, we will be subject to tax at corporate income tax rates and will not be able to deduct distributions to stockholders when computing our taxable income.
  • As a REIT, failure to make required distributions would subject us to federal corporate income tax.
  • We may be required to borrow funds, sell assets or raise equity to satisfy our REIT distribution requirements, to comply with asset ownership tests or to fund capital expenditures, future growth and expansion initiatives.
  • Complying with REIT requirements may limit our flexibility, cause us to forgo otherwise attractive opportunities that we would otherwise pursue to execute our strategic growth plan, or otherwise reduce our income and amounts available for distribution to our stockholders.
  • As a REIT, we are limited in our ability to fund distribution payments using cash generated through our TRSs.
  • Our extensive use of TRSs, including for certain of our international operations, may cause us to fail to remain qualified for taxation as a REIT.
  • Even if we remain qualified for taxation as a REIT, some of our business activities are subject to corporate level income tax and foreign taxes, which will continue to reduce our cash flows, and we will have potential deferred and contingent tax liabilities.
  • Complying with REIT requirements may limit our ability to hedge effectively and increase the cost of our hedging and may cause us to incur tax liabilities.
  • Distributions payable by REITs generally do not qualify for preferential tax rates, which could reduce the demand for and market price of our common stock.
  • The ownership and transfer restrictions contained in our certificate of incorporation may not protect our qualification for taxation as a REIT, could have unintended antitakeover effects and may prevent our stockholders from receiving a takeover premium.
  • Legislative or other actions affecting REITs could have a negative effect on us or our stockholders.
  • GENERAL RISK FACTORS
  • Our cash distributions are not guaranteed and may fluctuate.
  • Our business could be adversely impacted if there are deficiencies in our disclosure controls and procedures or internal control over financial reporting.
  • We face competition for customers.
  • The performance of our businesses relies on our ability to attract, develop, and retain talented personnel, while controlling our labor costs.

Legal proceedings

We are involved in litigation from time to time in the ordinary course of business. A portion of the defense and/or settlement costs associated with such litigation is covered by various commercial liability insurance policies purchased by us and, in limited cases, indemnification from third parties. In the opinion of management, no material legal proceedings are pending to which we, or any of our properties, are subject.
