PART I
Item 1. BUSINESS.
BUSINESS OVERVIEW
Iron Mountain Incorporated, a Delaware corporation ("IMI"), was founded in an underground facility near Hudson, New York in 1951 where it stored business records. Today, we are a global leader in information management services, and we are trusted by more than 240,000 customers in 61 countries, including approximately 95% of the Fortune 1000, to help unlock value and intelligence from their assets through services that transcend the physical and digital worlds. Our broad range of solutions address their information management, digital transformation, information security, data center and asset lifecycle management (“ALM”) needs. Our longstanding commitment to safety, security, sustainability and innovation in support of our customers underpins everything we do. We currently serve customers across an array of market verticals — commercial, legal, financial, healthcare, technology, insurance, life sciences, energy, business services, entertainment and government organizations.
We are listed on the New York Stock Exchange (the "NYSE") and are a constituent of the Standard & Poor’s 500 Index, the Morgan Stanley Capital International ("MSCI") REIT index and the FTSE EPRA Nareit Global Real Estate Index. As of December 31, 2024, we were number 604 on the Fortune 1000. We have been organized and have operated as a REIT beginning with our taxable year ended December 31, 2014.
BUSINESS STRATEGY
OVERVIEW
Our company has been a market leader in the physical ecosystem supporting information storage and retrieval, as most businesses have relied on paper documents or computer tapes to store their valuable information. Over time, customers are increasing their digital information, with the new information storage ecosystem being a hybrid of physical and digital media. We have evolved our business to meet our customers' needs while remaining focused on driving growth supported by our four pillars outlined below.
| Continued revenue growth in physical storage through revenue management actions as well as volume growth achieved in faster growing markets and our consumer business, as well as complementary business growth | •We are establishing and enhancing leadership positions in higher-growth markets such as central and eastern Europe, Latin America, Asia, the Middle East and Africa. •We continue to identify, acquire, incubate and scale complementary businesses and products to support our long-term growth objectives and drive solid returns on invested capital. These opportunities include our Global Digital Solutions, ALM, Fine Arts and Consumer Storage (each as defined below) businesses. | ||||
| Utilizing our global scale as well as over 70 years of customer trust to deliver differentiated data center offerings | •We have made significant progress in scaling our Global Data Center Business through acquisitions and organic growth, with 29 operating data centers across 21 global markets, either directly or through unconsolidated joint ventures. •As of December 31, 2024, we had leased approximately 96% of the existing 416 megawatt ("MW") capacity of our data centers. With a total potential capacity of 1,280 MW in land and buildings currently owned or operated by us, we are among the largest global data center operators. | ||||
| Establishing and maintaining a leadership position in critical digital infrastructure as well as developing and offering new products and services that allow our customers to achieve reliable and secure information management solutions in an increasingly hybrid physical and digital world | •We are positioned to take advantage of the secular growth trends of the changing nature of digital infrastructure. We continue to scale our Global Digital Solutions business to complement our existing offerings in records and information management, ALM, and our Global Data Center business in order to respond to our customers’ growing interest and need to react to environmental, social and corporate governance considerations. This full suite of complementary businesses puts Iron Mountain in a unique position to cross sell our products and services to our customers. •Our customers are faced with navigating a more complex regulatory environment, and one in which hybrid physical and digital solutions have become the norm. Our strategy is underpinned by our persistent focus on best-in-class customer experience, as we continue to seek innovative solutions to help our customers progress on their journey from physical storage to a digital ecosystem. | ||||

Part I
| Continued investment in our growth agenda, our business and customer-centric solutions | •We have established an investment strategy to fuel our growth. The investments we outlined in our plan for Project Matterhorn (as defined below) have been informed by our established leadership position in the physical storage business, our expanding services such as Global Digital Solutions and ALM and our significant progress in the Global Data Center Business. | ||||
PROJECT MATTERHORN
In September 2022, we announced a global program designed to accelerate the growth of our business ("Project Matterhorn"). Project Matterhorn investments focus on transforming our operating model to a global operating model. Project Matterhorn focuses on the formation of a solution-based sales approach that is designed to allow us to optimize our shared services and best practices to better serve our customers' needs. We are investing to accelerate growth and to capture a greater share of the large, global addressable markets in which we operate. We have incurred approximately $378.5 million in Restructuring and other transformation costs from the inception of Project Matterhorn through December 31, 2024. We expect to incur approximately $150.0 million in costs related to Project Matterhorn during the year ending December 31, 2025, at which point the program is expected to be completed. Costs are comprised of (1) restructuring costs, which include (i) site consolidation and other related exit costs, (ii) employee severance costs and (iii) certain professional fees associated with these activities, and (2) other transformation costs, which include professional fees such as project management costs and costs for third party consultants who are assisting in the enablement of our growth initiatives. Total costs related to Project Matterhorn during the years ended December 31, 2024 and 2023 were approximately $161.4 million and $175.2 million, respectively.

BUSINESS ATTRIBUTES
Our business has the following attributes:
Large, Diversified, Global Business ![]() | The world’s most heavily regulated organizations trust us with the storage of their records. Our mission-critical storage offerings and related services generated approximately $6.1 billion in annual revenue in 2024. Our business has a highly diverse customer base of more than 240,000 customers - with no single customer accounting for more than approximately 1% of revenue during the year ended December 31, 2024 - and operates in 61 countries globally. This presents a significant cross-sell opportunity for our expanding solutions, including digital, data center and ALM.![]() | ||||
Recurring, Durable Revenue Stream ![]() | A majority of our revenue is recurring in nature. In our Records Management business, our contracted storage rental fee agreements generally range from one to five years in length. As of December 31, 2024, we stored more than 730 million cubic feet of physical volume and we have consistently experienced strong customer retention levels. In our Global Data Center Business, our lease durations vary by customer, with a weighted average lease expiration of 10.6 years as of December 31, 2024. | ||||
Comprehensive Information Management Solution ![]() | As an S&P 500 REIT with approximately 1,350 locations globally and with offerings spanning physical storage, digitization solutions and digital storage, we are positioned to provide a holistic offering to our customers. We are able to cater to our customers’ physical and digital needs and to help guide their digital transformation journey. | ||||
Significant Owner and Operator of Real Estate ![]() | We operate approximately 98 million square feet of real estate worldwide. Our owned real estate footprint spans to over 24 million square feet. | ||||
Limited Revenue Cyclicality ![]() | Historically, economic downturns have not significantly affected our storage rental business.

Shifting Revenue Mix ![]() | We have identified a number of areas where we see opportunity for growth as we position ourselves to unlock greater value for our customers.

Part I
In addition, our Global Data Center Business has the following attributes:
Large Data Center Platform with Significant Expansion Opportunity ![]() | As of December 31, 2024, we had 416 MW of leasable capacity with an additional 864 MW under construction or held for development. | ||||
Differentiated Compliance and Security ![]() | We offer comprehensive compliance support as well as physical and cybersecurity. Our Security-in-Depth strategy integrates both technical and human security measures, with oversight provided by senior security leaders with military and public sector backgrounds. As of December 31, 2024, our data center portfolio has achieved numerous certifications and received third party assurance reports, making it one of the most comprehensive compliance programs in the industry. These certifications and reports on compliance include the global ISO 27001, ISO 22301, ISO 9001, SOC 2 and PCI-DSS standards, as well as HIPAA, NIST 800-53 and FISMA HIGH in the United States.

Efficient Access and Flexibility ![]() | We have the ability to provide customers with a range of deployment options from one cabinet to an entire building, leveraging our global portfolio of hyperscale-ready and underground data centers. We also provide access to numerous carriers, cloud providers and peering exchanges with migration support. | ||||
100% Clean Energy Data Centers ![]() | We have matched 100% of the energy consumption in our data centers with clean energy annually since 2017. This approach enables our Green Power Pass offering, which allows customers to report the power they consume at any Iron Mountain Data Center as clean power in their public reporting, making Iron Mountain a key part of their decarbonization roadmaps and goals. Our data center business is a founding signatory to the UN Compact on 24/7 Carbon-Free Energy (“CFE”), which seeks hour-by-hour matching of site consumption with local CFE by 2040. | ||||
COMPETITION
We face competition from numerous storage and information management services providers globally, as well as storage and information management services that are managed and operated internally by organizations. Competition for records and information customers is driven by factors such as pricing, reputation and reliability, the quality and security of storage solutions and the scope and scale of technology. While the majority of our competitors operate in only one market or region, we believe we provide a differentiated global offering that competes effectively in these areas.
We also compete with numerous data center developers, owners and operators, many of whom own properties comparable to ours in several of the same metropolitan areas where our facilities are located. We believe that competition for data center customers is based on availability of power, security measures, location, connectivity and rental rates, and we are confident in our ability to compete effectively in each of these areas. Additionally, we believe our strong brand, global footprint and excellent commercial relationships empower us to compete successfully and provide significant cross-selling opportunities with our existing customer base.
In our ALM business, we compete with both hyperscalers and individual corporate clients who manage their own asset recycling, disposition and management, in addition to external competitors.
HUMAN CAPITAL MANAGEMENT
EMPLOYEES
As of December 31, 2024, we employed approximately 11,150 employees in the United States and approximately 17,700 employees outside of the United States. As of December 31, 2024, approximately 375 employees were represented by unions in North America and approximately 1,375 employees were represented by unions in Latin America. All union employees are currently under renewed labor agreements or operating under an extension agreement.
| IRON MOUNTAIN 2024 FORM 10-K | 5 |
Part I
BENEFIT PROGRAMS
We provide our employees with benefits that are designed to support their overall physical, financial, emotional and social well-being. These benefits vary by location but generally include health and welfare benefits, paid time off and programs to support financial security. Additionally, employees are able to access emotional well-being resources through global employee assistance programs. Certain unionized employees receive benefits through unions and are not eligible to participate in our benefit programs. In addition to base compensation and other usual benefits, a significant portion of full-time employees participate in some form of incentive-based compensation program that provides payments based on revenues, profits or attainment of specific objectives for the unit in which they work.
COMPANY CULTURE
We are committed to making a meaningful impact on our customers, our people and our business by cultivating a culture that is firmly grounded in our values: Acting with Integrity, Owning Safety and Security, Building Customer Value, Taking Ownership and Promoting Inclusion and Teamwork.
While we foster an environment of learning, collaboration, diversity and wellbeing, we know culture truly thrives in the everyday experience of working at Iron Mountain.
Our culture encourages open communication and innovation while fostering trust, engagement and exceptional performance. We evaluate this through regular employee surveys and by leveraging data to gain a deeper understanding of our global workforce, and how they work. These insights collectively enable us to drive enhanced employee engagement, measure effectiveness and refine our approach for sustained success.
Led by our President and CEO, William Meaney, our Inclusive Leadership Alliance (the "Alliance") includes members of the Executive Leadership Team and plays a pivotal role in advancing our culture and driving growth. The Alliance reviews and supports key initiatives, monitors progress toward enterprise goals, ensures accountability through measurable targets and communicates achievements to stakeholders.
Our volunteer-based global employee resource groups play an essential role in supporting talent attraction, retention and development, and serving as valuable allies across our company. Each group is sponsored by one or more members of Iron Mountain’s Executive Leadership Team.
COMMUNITY INVOLVEMENT
We are committed to integrating responsible and sustainable practices throughout our organization to help our operations have a positive impact on the environment and the communities in which we operate. We aim to give back to the communities where we live and work and believe that this commitment helps in our efforts to attract and retain employees. We offer philanthropic support to our global community through our Living Legacy Initiative, which is our commitment to help preserve and make accessible cultural and historical information and artifacts. We encourage volunteerism in the communities in which we live and work through our Moving Mountains volunteer program, offering paid time off for employees to help community-based and civic-minded organizations.
INSURANCE
For strategic risk transfer purposes, we maintain a comprehensive insurance program with insurers that we believe to be reputable and which have adequate capitalization in amounts that we believe to be appropriate. Property insurance is purchased on a comprehensive basis, including flood and earthquake (including excess coverage), subject to certain policy conditions, sublimits and deductibles. Property is insured based upon the replacement cost of real and personal property, including leasehold improvements, business income loss and extra expense. Other types of insurance that we carry, which are also subject to certain policy conditions, sublimits and deductibles, include medical, workers’ compensation, general liability, umbrella, automobile, professional, cyber, warehouse legal liability and directors’ and officers’ liability policies.
GOVERNMENT REGULATION
We are required to comply with numerous laws and regulations covering a wide variety of subject matters which may have a material effect on our capital expenditures, earnings and competitive position.
| 6 | IRON MOUNTAIN 2024 FORM 10-K |
Part I
For example, some of our currently and formerly owned or leased properties were previously used by entities other than us for industrial or other purposes, or were affected by waste generated from nearby properties, that involved the use, storage, generation and/or disposal of hazardous substances and wastes, including petroleum products. In some instances, this prior use involved the operation of underground storage tanks or the presence of asbestos-containing materials. Where we are aware of environmental conditions that require remediation, we undertake appropriate activity, in accordance with all legal requirements. Although we have from time to time conducted limited environmental investigations and remedial activities at some of our former and current facilities, we have not undertaken environmental reviews of all of our properties. We therefore may be potentially liable for environmental costs and may be unable to sell, rent, mortgage or use contaminated real estate owned or leased by us. Under various federal, state and local environmental laws, we may be liable for environmental compliance and remediation costs to address contamination, if any, located at owned and leased properties as well as damages arising from such contamination, whether or not we know of, or were responsible for, the contamination, or the contamination occurred while we owned or leased the property. Environmental conditions for which we might be liable may also exist at properties that we may acquire in the future. In addition, future regulatory action and environmental laws may impose costs for environmental compliance that do not exist today.
We transfer a portion of our risk of financial loss due to currently undetected environmental matters by purchasing an environmental impairment liability insurance policy, which covers all owned and leased locations. Coverage is provided for both liability and remediation costs.
In addition, we are subject to numerous laws and regulations relating to data privacy and cybersecurity, which are complex, change frequently and have tended to become more stringent over time. We have an established global privacy compliance framework and devote substantial resources, and may in the future have to devote significant additional resources, to facilitate compliance with these laws and regulations, and to investigate, defend or remedy actual or alleged violations or breaches. Any failure by us to comply with, or remedy any violations or breaches of, these laws and regulations could negatively impact our operations, result in the imposition of fines and penalties, liability and litigation, significant costs and expenses and reputational harm.
For more information about laws and regulations that could affect our business, see "Item 1A. Risk Factors" included in this Annual Report.
SUSTAINABILITY
At Iron Mountain, we are using our influence and expertise to drive innovations that protect and elevate the effectiveness of our customers’ endeavors, while also creating a meaningful, positive impact on individuals, the environment, and our overall performance. Iron Mountain is committed to sustainable growth, and this is highlighted through initiatives and targets within our company. We aim to minimize our environmental impact, foster a culture and processes that support the well-being of our global teams, and to be a catalyst for positive change within our communities.
We transparently report on our sustainability efforts and the advancement of our objectives by using widely adopted reporting frameworks such as the Global Reporting Initiative, CDP and EcoVadis. In addition, we continue to further align our reporting with the recommendations of the Financial Stability Board’s Task Force on Climate-related Financial Disclosures.
Our work continues to receive recognition. In 2024, the Science Based Targets initiative ("SBTi") validated our targets, which are aligned with the Paris Climate Agreement aspiration of limiting the global temperature increase to 1.5 degrees Celsius. Our data center team was recognized with the Decarbonization of Electricity award from BroadGroup International for their work and thought leadership on carbon-free energy.
As of December 31, 2024, we are a constituent of multiple indexes that focus on corporate sustainability standards, including several MSCI All Country World Indexes (ACWI), such as the ACWI Low Carbon Leaders, ACWI Climate Paris Aligned, ACWI ESG Leaders and ACWI Socially Responsible Index (SRI). We have also been a constituent of the FTSE4Good Index for more than ten years. A copy of our sustainability report is available on the "Who we are" section of our website, www.ironmountain.com, under the heading "Sustainability". We are not including the information contained on or available through our website as part of, or incorporating such information by reference into, this Annual Report.

our inability to maintain relationships with key customers and suppliers or to execute on our plan to incorporate the digitization of our customers’ records and new digital information technologies into our offerings;
-
failure to achieve satisfactory returns on new product offerings, acquired companies, joint ventures, growth initiatives or other investments, particularly in markets where we do not currently operate or have a substantial presence;
-
our inability to identify suitable companies to acquire, invest in or partner with;
-
our inability to complete acquisitions or investments on satisfactory terms;
-
our inability to structure acquisitions or investments in a manner that complies with our debt covenants or is consistent with our leverage ratio goals;
-
challenges in managing costs to offset the impact of inflationary pressure;
-
increased demands on our management, operating systems, internal controls and financial and physical resources and, if necessary, our inability to successfully expand our infrastructure;
-
incurring additional debt necessary to acquire suitable companies or make other growth investments if we are unable to pay the purchase price or make the investment out of working capital or the issuance of our common stock or other equity securities;
-
our inability to manage the budgeting, forecasting and other process control issues presented by future growth, particularly with respect to new lines of business;
-
insufficient revenues to offset expenses and liabilities associated with new investments; and
-
our inability to attract, develop and retain skilled employees to lead and support our strategic growth plan, particularly in new businesses, technologies, products or offerings outside our core competencies.
Our new ventures are inherently risky and we can provide no assurance that such strategies and offerings will be successful in achieving the desired returns within a reasonable timeframe, if at all, and that they will not adversely affect our business, reputation, financial condition and operating results.
If stored records and tapes become less active, our service revenue growth and profits from related services may decline.
Our Records Management and Data Management service revenue growth is being negatively impacted by declining activity rates as stored records and tapes are becoming less active and more archival. The amount of information available to customers digitally or in their own information systems has been steadily increasing in recent years, and we believe this trend will continue. As a result, our customers are less likely than they have been in the past to retrieve records and rotate tapes, thereby reducing their activity levels. At the same time, many of our costs related to records and tape related services remain relatively fixed. In addition, our reputation for providing secure information storage is critical to our success, and actions to manage cost structure, such as outsourcing certain transportation, security or other functions, could negatively impact our reputation and adversely affect our business, and, if we are unable to appropriately align our cost structure with decreased levels of service activity, our operating results could be adversely affected.

Part I
Our customers continue to evolve the way they store records, which could impact our storage revenue.
We derive substantial revenues from rental fees for the storage of physical records and computer backup media and from storage related services. Volume in and demand for our traditional storage related services has evolved as our customers adopt alternative storage technologies or as retention requirements change, which may require significantly less space than traditional physical records and tape storage; however, volumes in our Global RIM Business segment were relatively steady in 2024 and we expect them to remain relatively consistent in the near term. We can provide no assurance that our customers will continue to store most or a portion of their records as paper documents or as tapes, or that the paper documents or tapes they do store with us will require our storage related services at the same levels as they have in the past. A significant shift by our customers to storage of data through non-paper or non-tape-based technologies, whether now existing or developed in the future, could adversely affect our businesses. In addition, the digitization of records may shift our revenue mix from the more predictable storage revenue to service revenue, which is inherently more volatile.
We and our customers are subject to laws and governmental regulations 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.
We and our customers are subject to numerous laws and regulations relating to data privacy and cybersecurity. These regulations are complex, change frequently and have tended to become more stringent over time. In addition, a growing number of regulatory bodies have adopted data breach notification requirements and increased enforcement of regulations regarding the use, access, accuracy and security of personal information. Finally, as a result of the continued emphasis on information security and instances in which personal information has been compromised, our customers are requesting that we take increasingly sophisticated measures to enhance security and comply with cybersecurity and data privacy regulations and that we assume higher liability under our contracts.
We have an established global privacy compliance program and devote substantial resources, and may in the future have to devote significant additional resources, to facilitate compliance with global laws and regulations, our customers’ data privacy, data residency and security demands, and to investigate, defend or remedy actual or alleged violations or breaches. Any failure by us to comply with, or remedy any violations or breaches of, laws and regulations or customer requirements could negatively impact our operations, result in the imposition of fines and penalties, contractual liability and litigation, significant costs and expenses and reputational harm.
Expansion into Global Digital Solutions and ALM services means that our privacy and security risk profile is increasing. In particular, we are hosting increasing volumes of customer digital data, including sensitive and confidential data, and disposing of customer data-bearing devices. This may result in increased regulatory exposure, contractual liability and security expectations from customers. Finall

Item 1C. CYBERSECURITY.
RISK MANAGEMENT AND STRATEGY
We maintain a robust information security program that is designed to protect our information and the information of our customers. Our information security program is based on a recognized cybersecurity framework established by the National Institute of Standards and Technology ("NIST") and establishes controls to mitigate critical areas of cybersecurity risk. Our information security program has adopted all elements of the NIST cybersecurity framework, including the six functions of identify, protect, detect, respond, recover and govern, as well as each of the categories and control groups thereunder. This does not imply that we meet any particular technical standards, specifications, or requirements, but only that we use the NIST framework as a guide to ensure our information security program is designed to manage cybersecurity risks relevant to our business. Among other things, the cybersecurity controls in our information security program address information access rights, incident monitoring and response processes, information technology system configuration, network security, security architecture planning, mobile device security and compliance with information security policy requirements and protocols. These cybersecurity controls are designed to oversee, identify and mitigate risks from all cybersecurity threats, including those arising from our use of third-party service providers. Our cybersecurity controls are evaluated regularly by our internal information security team, and we engage a third party examiner to assess the maturity of our information security program against the NIST cybersecurity framework no less frequently than bi-annually. Additionally, our information security program is assessed periodically by a federal regulator in the United States as part of its routine audit of the Company. In addition to our internal assessments, we also assess our third-party service providers on a regular basis using a risk-based approach that assigns a risk calculation to each such service provider. The results of our assessments are tracked and evaluated to ensure these third parties comply with our cybersecurity standards. We require all employees to undertake data protection and cybersecurity training and compliance programs annually.

Part I
Our reputation for providing secure information storage to customers is critical to the success of our business, and protecting against material cybersecurity risks is an integral part of maintaining that reputation. A successful cybersecurity breach could lead to theft or misuse of our or our customers’ proprietary or confidential information or our employees’ personal information and result in third-party claims against us, regulatory penalties and reputational harm. As part of our information security program, we also actively monitor emerging cyberattack patterns to develop custom detection capabilities and mitigation techniques to protect against material risk of cybersecurity threats. Upon encountering a cybersecurity incident, our information security team responds using our detailed cybersecurity incident response plan ("CSIRP"), which is based on industry best practices, relevant legal requirements and our contractual commitments. Among other things, the CSIRP sets forth the specific criteria used to assess a cybersecurity incident, mitigate risks of adverse consequences associated with any such incident, protocols to escalate the management of the incident and the process to inform our executive management team and any impacted functions of our business. All cybersecurity incidents are assessed to determine whether disclosure is required pursuant to any contractual or regulatory requirements and any material cybersecurity incident is also reported to our board of directors (our "Board").
To date, our information security program has been successful in protecting against risks from cybersecurity threats, and we have not had any cybersecurity incidents that have materially affected or are reasonably likely to materially affect our business strategy, results of operations or financial condition. Additional information about cybersecurity risks we face is discussed in Item 1A of Part I, “Risk Factors,” under the heading “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”, which should be read in conjunction with the information above.
GOVERNANCE
Our Board reviews and discusses significant risks with executive management, including cybersecurity risk, that affect us. Although our executive management team and our Board work together on risk matters, our Board has the ultimate oversight authority over all enterprise risks, including cybersecurity risk. Our Board reserves the right to, and periodically does, consult with third-party advisors and experts to assist our Board in understanding and anticipating future cybersecurity threats and trends. The risk and safety committee of our Board (the "RSC") is specifically tasked with reviewing and monitoring cybersecurity and information security risk, as well as the risk management strategies, systems and policies, and processes implemented, established and reported on by our executive management team. The RSC is also primarily responsible for assisting our Board with oversight of our enterprise risk management program.
Our executive management team, with oversight from our Board, is responsible for our enterprise risk management process and the day-to-day supervision and mitigation of enterprise risks, including cybersecurity risk. Our enterprise risk management program includes our executive management team receiving regular reports from our operations personnel. As part of our enterprise risk program, our executive management team has established an enterprise risk committee (the "ERC"), which is chaired by our Chief Risk Officer and is otherwise composed of each of our other executive vice presidents. The ERC oversees our risk and compliance activities to ensure that management has appropriate policies and management plans in place for managing risks of the business, including cybersecurity risk, as well as reviewing and prioritizing significant risks and allocating resources for risk mitigation.
Our Chief Risk Officer provides reports at each meeting of the RSC on areas of potential risks to us, including cybersecurity risk, and our Chief Information Security Officer provides quarterly reports to the RSC on the key performance indicators of our information security program to facilitate the RSC’s oversight of the program through objective measurements, including metrics regarding software patching, IT asset management, cyber incident management and cybersecurity training. Reports by our Chief Information Security Officer also include detailed information on the activities of our cyber incident response team to allow for analysis of trends and the identification of any control gaps that require remediation.
We also maintain a business information security committee (the "ISC") with employee representation across geographies, business lines and business functions. The ISC includes a cross functional group of our employees with expertise and responsibilities in areas such as operations, digital product solutions, information technology, compliance, security, finance, privacy, internal audit and legal risk mitigation. The ISC is managed by our Chief Information Security Officer and meets regularly to receive updates on our cybersecurity posture, emerging risks and new cybersecurity capabilities. Members of the ISC act as points of contact during incident response activities to provide oversight and logistical support to the information security team.
The information security team is made primarily of full-time employees; however, we routinely engage consultants to provide supplemental labor and additional expertise in specific areas on an as-needed basis. Our information security team is organized based on industry best practices in alignment with NIST recommendations. All of the leaders in our information security team have over 10 years of cybersecurity experience and most of our information security staff maintain cybersecurity program certifications such as CMU Cybersecurity Executive Certification, ISACA Certifications (CISSP & CISM) and other relevant vendor certifications. Our information security team also regularly undergoes continuing education to ensure our implementation of best-in-class techniques.

The leased facilities typically have initial lease terms of five to 10 years with one or more renewal options. In addition, some of the leases contain either a purchase option or a right of first refusal upon the sale of the property. We believe that the space available in our facilities is adequate to meet our current needs, although future growth may require that we lease or purchase additional real property.

OVERVIEW
PROJECT MATTERHORN
In September 2022, we announced Project Matterhorn, a global program designed to accelerate the growth of our business. Project Matterhorn investments focus on transforming our operating model to a global operating model. Project Matterhorn focuses on the formation of a solution-based sales approach that is designed to allow us to optimize our shared services and best practices to better serve our customers' needs. We are investing to accelerate growth and to capture a greater share of the large, global addressable markets in which we operate. We have incurred approximately $378.5 million in Restructuring and other transformation costs from the inception of Project Matterhorn through December 31, 2024. We expect to incur approximately $150.0 million in costs related to Project Matterhorn during the year ending December 31, 2025, at which point the program is expected to be completed. Costs are comprised of (1) restructuring costs, which include (i) site consolidation and other related exit costs, (ii) employee severance costs and (iii) certain professional fees associated with these activities, and (2) other transformation costs, which include professional fees such as project management costs and costs for third party consultants who are assisting in the enablement of our growth initiatives. The following chart presents (in thousands) total Restructuring and other transformation costs related to Project Matterhorn from the inception of Project Matterhorn through December 31, 2024 and for the years ended December 31, 2024 and 2023:

GENERAL
RESULTS OF OPERATIONS - KEY TRENDS
-
Our organic storage rental revenue growth is primarily driven by revenue management in our Global RIM Business segment, where we expect volume to be relatively stable in the near term, as well as by growth in our Global Data Center Business segment, primarily driven by lease commencements.
-
Our organic service revenue growth is primarily due to increases in our service activity. We expect organic service revenue growth in 2025 to benefit from our new and existing Global Digital Solutions offerings and ALM, as well as our traditional services.
-
We expect continued total revenue and Adjusted earnings before interest, taxes, depreciation and amortization ("EBITDA") growth in 2025 as a result of our focus on new product and service offerings, innovation, customer solutions and market expansion in line with our Project Matterhorn objectives.
Our revenues consist of storage rental revenues and service revenues and are reflected net of sales and value-added taxes. Storage rental revenues, which are considered a key driver of financial performance for the storage and information management services industry, consist primarily of recurring periodic rental charges related to the storage of materials or data (generally on a per unit basis) that are typically retained by customers for many years and of revenues associated with our data center operations. Service revenues include charges for related service activities, the most significant of which include: (1) the handling of records, including the addition of new records, temporary removal of records from storage, refiling of removed records, customer termination and permanent withdrawal fees, project revenues and courier operations, consisting primarily of the pickup and delivery of records upon customer request; (2) secure shredding of sensitive documents and the subsequent sale of shredded paper for recycling, the price of which can fluctuate from period to period; (3) the decommissioning, data erasure, processing and disposition, and recycling or sale of IT hardware and component assets; (4) digital solutions, including the scanning, imaging and document conversion services of active and inactive records, consulting services and the sale of software as a service; and (5) data center services, including set up, monitoring and support of our customers' assets which are protected in our data center facilities, and special project services, including data center fitout.
Cost of sales (excluding depreciation and amortization) consists primarily of labor, including wages and benefits for field personnel, facility occupancy costs (including rent and utilities), data center pass-through power costs, transportation expenses (including vehicle leases and fuel), other product cost of sales and other equipment costs and supplies. Of these, labor and facility occupancy costs are the most significant. Selling, general and administrative expenses consist primarily of wages and benefits for management, administrative, IT, sales, account management and marketing personnel, as well as expenses related to communications, travel, professional fees, bad debts, training, office equipment and supplies.

| Trends in facility occupancy costs are impacted by: •the total number of facilities we occupy; •the mix of properties we own versus properties we lease; •fluctuations in per square foot occupancy costs; •the levels of utilization of these properties; and •data center power costs. Trends in total wages and benefits in dollars and as a percentage of total revenue are influenced by: •changes in headcount and compensation levels; •achievement of incentive compensation targets; •workforce productivity; and •variability in costs associated with medical insurance and workers’ compensation. | |||||
Our depreciation and amortization charges result primarily from depreciation related to storage systems, which include buildings, building and leasehold improvements, data center infrastructure, racking structures and computer systems hardware and software. Amortization relates primarily to customer and supplier relati

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.
CREDIT RISK
Financial instruments that potentially subject us to credit risk consist principally of cash and cash equivalents (including money market funds and time deposits) and accounts receivable. We had no significant concentrations of liquid investments as of December 31, 2024. As per our risk management investment policy, we limit exposure to concentration of credit risk by limiting the amount invested in any one mutual fund to a maximum of 1% of the fund's total assets or in any one financial institution to a maximum of $75.0 million. As of December 31, 2024, our cash and cash equivalents balance was $155.7 million.
INTEREST RATE RISK
Given the recurring nature of our revenues and the long-term nature of our asset base, we have the ability and the preference to use long-term, fixed interest rate debt to finance our business at attractive rates, thereby helping to preserve our long-term returns on invested capital. Occasionally, we may use interest rate swaps as a tool to maintain our targeted level of fixed rate debt.
As of December 31, 2024, approximately 14.4%, or $1,989.4 million, of our total long-term debt outstanding was subject to variable interest rates. If the weighted average variable interest rate on our variable rate debt had increased by 1%, our net income for the year ended December 31, 2024 would have been reduced by approximately $23.2 million.
See Note 6 to Notes to Consolidated Financial Statements included in this Annual Report for a discussion on our interest rate swaps and Note 7 to Notes to Consolidated Financial Statements included in this Annual Report for a discussion of our long-term indebtedness, including the fair values of such indebtedness as of December 31, 2024.
CURRENCY RISK
Our international investments may be subject to risks and uncertainties related to fluctuations in currency valuation. Our reporting currency is the United States dollar. However, our international revenues and expenses are generated in the currencies of the countries in which we operate, primarily the British pound sterling, Euro, Canadian dollar and Australian dollar. Declines in the value of the local currencies in which we are paid relative to the United States dollar will cause revenues in United States dollar terms to decrease and dollar-denominated liabilities to increase in local currency. The impact of currency fluctuations on our earnings is mitigated by the fact that most operating and other expenses are also incurred and paid in the local currency. We also have several intercompany obligations with and between certain of our subsidiaries of differing functional currencies, resulting in foreign transaction gains or losses based on period-end exchange rates.
We have adopted and implemented a number of strategies to mitigate the risks associated with fluctuations in foreign currency exchange rates. One strategy is to finance certain of our international subsidiaries with debt that is denominated in local currencies, thereby providing a natural hedge. In determining the amount of any such financing, we take into account local tax considerations, among other factors. Another strategy we utilize is for IMI or IMIM to borrow in foreign currencies to hedge our intercompany financing activities. In addition, on occasion, we enter into currency swaps to temporarily or permanently hedge an overseas investment, such as a major acquisition, to lock in certain transaction economics. IM UK has financed a portion of its capital needs through the issuance of the GBP Notes and through borrowings under the UK Bilateral Revolving Credit Facility, each of which are denominated in British pounds sterling. Our Australian business has financed a portion of its capital needs through direct borrowings in Australian dollars under the AUD Term Loan. This creates a tax efficient natural currency hedge.
We have entered into cross-currency swap agreements to hedge the variability of exchange rate impacts between the United States dollar and certain of our functional foreign currencies, including the Euro and the Canadian dollar. These cross-currency swap agreements are designated as a hedge of net investment against certain of our Euro and Canadian dollar denominated subsidiaries and require an exchange of the notional amounts at maturity. These cross-currency swap agreements are marked to market at the end of each reporting period, representing the fair values of the cross-currency swap agreements, and any changes in fair value are recognized as a component of Accumulated other comprehensive items, net. Unrealized gains are recognized as assets, which are recorded as either a component of (i) Prepaid expenses and other or (ii) Other within Other assets, net, while unrecognized losses are recognized as liabilities, which are recorded as either a component of (i) Accrued expenses and other current liabilities or (ii) Other long-term liabilities in our Consolidated Balance Sheets.
See Note 6 to Notes to Consolidated Financial Statements included in this Annual Report for a discussion on our cross-currency swap agreements.
| 56 | IRON MOUNTAIN 2024 FORM 10-K |
Part II
The impact of devaluation or depreciating currency on an entity depends on the residual effect on the local economy and the ability of an entity to raise prices and/or reduce expenses. Due to our constantly changing currency exposure and the potential substantial volatility of currency exchange rates, we cannot predict the effect of exchange fluctuations on our business. The effect of a change in foreign currency exchange rates on our net investment in foreign subsidiaries is reflected in the "Accumulated Other Comprehensive Items, net" component of equity. A 10% depreciation in year-end 2024 functional currencies, relative to the United States dollar, would result in a reduction in our equity of $335.6 million.

Item 9A. CONTROLS AND PROCEDURES.
DISCLOSURE CONTROLS AND PROCEDURES
The term "disclosure controls and procedures" is defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. These rules refer to the controls and other procedures of a company that are designed to ensure that information is recorded, processed, accumulated, summarized, communicated and reported to management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding what is required to be disclosed by a company in the reports that it files under the Exchange Act. As of December 31, 2024 (the "Evaluation Date"), we carried out an evaluation, under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of our disclosure controls and procedures. Based upon that evaluation, our chief executive officer and chief financial officer concluded that, as of the Evaluation Date, our disclosure controls and procedures are effective.
MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
Our management, with the participation of our principal executive officer and principal financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our internal control system is designed to provide reasonable assurance to our management and board of directors regarding the preparation and fair presentation of published financial statements. Due to their inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions or that the degree of compliance with policies or procedures may deteriorate. Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2024.
The effectiveness of our internal control over financial reporting has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which is included in this Annual Report.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the shareholders and the Board of Directors of Iron Mountain Incorporated
OPINION ON INTERNAL CONTROL OVER FINANCIAL REPORTING
We have audited the internal control over financial reporting of Iron Mountain Incorporated and subsidiaries (the "Company") as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2024, of the Company and our report dated February 14, 2025, expressed an unqualified opinion on those financial statements.
BASIS FOR OPINION
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
DEFINITION AND LIMITATIONS OF INTERNAL CONTROL OVER FINANCIAL REPORTING
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the shareholders and the Board of Directors of Iron Mountain Incorporated
OPINION ON THE FINANCIAL STATEMENTS
We have audited the accompanying consolidated balance sheets of Iron Mountain Incorporated and subsidiaries (the "Company") as of December 31, 2024 and 2023, the related consolidated statements of operations, comprehensive income (loss), (deficit) equity, and cash flows, for each of the three years in the period ended December 31, 2024, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 14, 2025, expressed an unqualified opinion on the Company's internal control over financial reporting.
BASIS FOR OPINION
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
CRITICAL AUDIT MATTER
The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Part IV
GOODWILL - ASSET LIFECYCLE MANAGEMENT REPORTING UNIT - REFER TO NOTE 2.L. TO THE FINANCIAL STATEMENTS
CRITICAL AUDIT MATTER DESCRIPTION
The Company’s evaluation of goodwill for impairment involves the comparison of the fair value of the reporting unit to its carrying value. The Company determined the fair value of the Asset Lifecycle Management reporting unit based on the present value of future cash flows (the "Discounted Cash Flow Model"). The determination of the fair value using the Discounted Cash Flow Model requires management to make significant assumptions related to future revenue growth rates, operating margins, and discount rates. Changes in economic and operating conditions impacting these assumptions could result in goodwill impairment in future periods. The goodwill balance allocated to the Asset Lifecycle Management reporting unit was $748.0 million as of October 1, 2024 (goodwill impairment testing date). The fair value of the Asset Lifecycle Management reporting unit exceeded its carrying value as of the measurement date and, therefore, no impairment was recognized.
We identified the evaluation of goodwill for the Asset Lifecycle Management reporting unit for impairment as a critical audit matter because of the significant judgments made by management to estimate the fair value of the Asset Lifecycle Management reporting unit. Performing audit procedures to evaluate the reasonableness of management’s estimates and assumptions related to selection of the discount rate and forecasts of future revenue and operating margin of the Asset Lifecycle Management reporting unit required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists.
