ITEM 1. BUSINESS. 

BUSINESS OVERVIEW

We help organizations around the world protect their information, reduce storage costs, comply with regulations, facilitate corporate 
disaster recovery, and better use their information and IT infrastructure for business advantages, regardless of its format, location 
or life cycle stage. We do this by storing physical records and data backup media, offering information management solutions, and 
providing data center space for enterprise-class colocation and hyperscale deployments. We offer comprehensive records and 
information management services and data management services, along with the expertise and experience to address complex 
storage and information management challenges such as rising storage rental costs, legal and regulatory compliance, and disaster 
recovery requirements. We provide secure and reliable data center facilities to protect digital information and ensure the continued 
operation of our customers’ IT infrastructure, with reliable and flexible deployment options. Our asset lifecycle management ("ALM") 
business allows us to provide end-to-end asset lifecycle services for hyperscale, corporate data center and corporate end-user 
device assets.

Founded in an underground facility near Hudson, New York in 1951, Iron Mountain Incorporated, a Delaware corporation, has more 
than 225,000 customers in a variety of industries in 60 countries around the world, as of December 31, 2022. We currently serve 
customers across an array of market verticals - commercial, legal, financial, healthcare, insurance, life sciences, energy, business 
services, entertainment and government organizations, including approximately 95% of the Fortune 1000. As of December 31, 
2022, we employed approximately 26,000 people. We are listed on the New York Stock Exchange (the "NYSE") and are a 
constituent of the Standard & Poor’s 500 Index and the MSCI REIT index. As of December 31, 2022, we were number 652 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 
are a different company to the one we have been in our past. The strategic journey we are on is driving this change and our focus 
remains on the four pillars outlined below to grow our business.

Continued growth in physical storage 
through revenue management as well 
as volume growth achieved in faster 
growing emerging markets and 
consumer and complementary 
business growth in developed markets

Utilizing our global scale as well as 
over 70 years of customer trust to 
deliver differentiated data center 
offerings

• We are establishing and enhancing leadership positions in higher-growth 

markets such as central and eastern Europe, Latin America, Asia and Africa, 
through both organic expansion and acquisitions in countries where GDP growth 
is faster and outsourcing information management is at an earlier stage.

• 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 digital services and our 
ALM, Entertainment Services, Fine Arts and Consumer Storage (each as 
defined below) businesses.

• We have made significant progress in scaling our Global Data Center Business 
through acquisitions and organic growth, with 21 operating data centers across 
19 global markets, either directly or through unconsolidated joint ventures. 
• As of December 31, 2022, approximately 92% of our data center capacity was 
leased. With total potential capacity of 747 megawatts ("MW") in land and 
buildings currently owned or operated by us, we are among the largest global 
data center operators.

Part I

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

• 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.

Increased 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 
enabled by the success of Project Summit, which was completed in 2021, and 
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 will focus on transforming our operating model to a global operating model. Project Matterhorn will 
focus 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 will be investing to accelerate growth and to capture a greater share of the 
large, global addressable markets in which we operate. We expect to incur approximately $150.0 million in costs annually related to 
Project Matterhorn from 2023 through 2025. 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 our growth initiatives. Total costs related to Project Matterhorn during the year ended 
December 31, 2022 were approximately $41.9 million.

BUSINESS SEGMENTS

The amount of revenues derived from our business segments and other relevant data, including financial information about 
geographic areas and product and service lines, for the years ended December 31, 2022, 2021 and 2020, are set forth in Note 11 
to Notes to Consolidated Financial Statements included in this Annual Report.

containers we provide and is a natural extension of our hardcopy records management operations, completing the lifecycle of a 
record. Through a combination of shredding facilities and mobile shredding units consisting of custom built trucks, we are able to 
offer secure shredding services to our customers.

GLOBAL DATA CENTER BUSINESS

The Global Data Center Business segment provides enterprise-class data center facilities and hyperscale-ready capacity to protect 
mission-critical assets and ensure the continued operation of our customers’ IT infrastructure with secure, reliable and flexible data

Part I

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 $5.1 billion in 
annual revenue in 2022. Our business has a highly diverse customer base of more than 225,000 
customers - with no single customer accounting for more than approximately 1% of revenue 
during the year ended December 31, 2022 - and operates in 60 countries globally. This presents 
a significant cross-sell opportunity for our expanding solutions, including digital, data center and 
ALM.

Recurring, Durable 
Revenue Stream

We generate a majority of our revenues from contracted storage rental fees, via agreements that 
generally range from one to five years in length. Historically, in our Records Management 
business, we have seen strong customer retention (of approximately 98%) and solid physical 
records retention; more than 50% of physical records that entered our facilities 15 years ago are 
still with us today. We have also seen strong customer retention in our Global Data Center 
Business.

Comprehensive 
Information
Management Solution

As an S&P 500 REIT with approximately 1,400 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 97 million square feet of real estate worldwide. Our owned real estate 
footprint spans nearly 23 million square feet.

Limited Revenue 
Cyclicality

Historically, economic downturns have not significantly affected our storage rental business. Due 
to the durability of our total global physical volumes, the success of our revenue management 
initiatives, and the growth of our Global Data Center Business, we believe we can continue to 
grow organic storage rental revenue over time.

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. These business lines, including Global Data 
Center, ALM, Fine Arts, Entertainment Services and Consumer Storage, represent markets with 
strong secular growth.

In addition, our Global Data Center Business has the following attributes:

Large Data Center
Platform with Significant
Expansion Opportunity

As of December 31, 2022, we had 192 MW of leasable capacity with an additional 556 
MW under construction or held for development.

Differentiated Compliance
and Security

Efficient Access
and Flexibility

100% Green Powered
Data Centers

COMPETITION

We offer comprehensive compliance support and physical and cyber security. Our 
Security-in-Depth approach to security includes a combination of technical and human 
security measures, and experienced senior military and public sector security leaders 
oversee our security. As of December 31, 2022, our data centers comply with one of the 
most comprehensive compliance programs in the industry, including enterprise-wide 
certified ISO 14001 and 50001 environmental and energy management systems. We 
also report globally on service organizational controls, as well as global ISO 27001 
certification, and PCI-DSS compliance, and meet FISMA HIGH and FedRAMP controls 
in the United States.

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 and IT.

As of December 31, 2022, our Global Data Center platform continues to match 100% of 
its consumption with renewable electricity procurement and benefits from low power 
usage effectiveness ("PUE"). We are one of the top 30 buyers of renewable energy 
among the Fortune 1000 and offer the Green Power Pass, which allows customers to 
include the power they consume at any Iron Mountain data centers as green power in 
their CDP, RE100, GRI, or other sustainability reporting.

We compete with thousands of storage and information management services providers around the world as well as storage and 
information management services managed and operated internally by organizations. We believe that competition for records and 
information customers is based on price, reputation and reliability, quality and security of storage, quality of service and 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 similar to ours in 
some 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 considerations, location, connectivity and rental rates, and we generally believe we compete 
effectively in each of these areas. Additionally, we believe our strong brand, global footprint and excellent commercial relationships 
enable us to compete successfully and provide significant cross-sell opportunities with our existing customer base.

Similarly, in our ALM business, we compete with both hyperscalers and individual corporate clients who manage their own asset 
recycling and management, as well as external competitors.

HUMAN CAPITAL MANAGEMENT

EMPLOYEES

As of December 31, 2022, we employed approximately 10,000 employees in the United States and approximately 16,000 
employees outside of the United States. As of December 31, 2022, approximately 400 employees were represented by unions in 
North America and approximately 1,200 employees were represented by unions in Latin America. All union employees are currently 
under renewed labor agreements or operating under an extension agreement.

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 recognize that an inspired culture is foundational to how we deliver on our purpose and create sustained growth and value for 
our shareholders. Iron Mountain's culture is deeply rooted in its enduring values: Act with Integrity, Own Safety and Security, Build 
Customer Value, Take Ownership and Promote Inclusion and Teamwork. While Iron Mountain is a culture of learning, 
collaboration, diversity and well-being, we know that culture overall comes down to what it feels like to work at Iron Mountain. This 
is why we celebrate and recognize our employees who consistently demonstrate Iron Mountain's values in measurable ways while 
inspiring others to do the same. We commit significant resources to sustaining a culture that enables voice and innovation, and 
facilitates trust, engagement, belonging and performance. We regularly survey our employees on a range of topics to measure our 
engagement and effectiveness and to obtain their views. In addition, we use data to gain insight to the global distribution of our 
employees, where they work, how they work and cost to serve. We use all of this information to drive increased employee 
engagement and success, as well as to refine our approach. 

DIVERSITY, EQUITY AND INCLUSION 

At Iron Mountain, we believe that an inclusive environment with diverse teams produces more creative solutions, results in better, 
more innovative products and services and is crucial to our efforts to attract and retain key talent. As one of our five core company 
values, Promoting Inclusion and Teamwork is a behavior all of our employees are expected to demonstrate every day. We have 
prioritized diversity, equity and inclusion ("DEI") as part of our corporate-wide strategic goals. Steps we have taken to create and 
sustain a more diverse, equitable and inclusive environment include: hiring a Global Chief Diversity, Equity & Inclusion Officer with 
significant DEI experience to lead our cultural transformation, and to lead us on the path to creating an environment of 
inclusiveness and belonging. Our Global Chief Diversity, Equity & Inclusion Officer works closely with our executive team, Human 
Resources, Environmental, Social and Governance ("ESG") and the DEI Councils and our Employee Resource Groups, all of 
whom support our DEI strategy in a variety of capacities. We also have a Global DEI Council which is comprised of the executive 
team and is chaired by our Chief Executive Officer. The Global DEI Council supports our DEI strategy and initiatives, monitors the 
progress of DEI initiatives and the enterprise goals, ensures accountability based upon identified measures and goals and 
communicates DEI progress to stakeholders. In 2021, we established the following goals: by 2025, women will represent at least 
40% of global leadership roles and individuals from historically underrepresented groups will represent at least 30% of US 
leadership roles. The Global DEI Council is not only responsible for providing the resources to help us reach our goals but also 
acting aggressively to retain our talent. We review and revise our systems, policies and processes to ensure that our organizational 
structures facilitate inclusiveness and accountability. We ensure that our recruiting efforts reflect our diversity goals and we launch, 
expand and support Employee Resource Groups, who meet and connect on shared characteristics and life experiences that can 
prove impactful to our business, our customers and our employees.

COMMUNITY INVOLVEMENT

We are committed to integrating responsible and sustainable practices throughout our organization to help our operations to 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 that 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

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.

For example, some of our current 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 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.

ITEM 1A. RISK FACTORS.

We face many risks. If any of the events or circumstances described below actually occur, we and our businesses, financial 
condition or results of operations could suffer, and the trading price of our debt or equity securities could decline. Our current and 
potential investors should consider the following risks and the information contained under the heading "Cautionary Note Regarding 
Forward-Looking Statements" before deciding to invest in our securities.

BUSINESS RISKS

Failure to execute our strategic growth plan may adversely impact our financial condition and results of operations.

As part of our strategic growth plan, including Project Matterhorn, we expect to invest in our existing businesses, including records 
and information management storage and services businesses in our higher-growth markets, data centers, ALM business and 
other complementary businesses, and in new businesses, business strategies, products, services, technologies and geographies. 
These initiatives may involve significant risks and uncertainties, including:

• 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 and 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 may shift from paper and tape storage to alternative technologies that may shift our revenue mix away from storage 
revenue.

We derive substantial revenues from rental fees for the storage of physical records and computer backup media and from storage 
related services. Storage volume and/or demand for our traditional storage related services may decline as our customers adopt 
alternative storage technologies or as retention requirements evolve, which may require significantly less space than traditional 
physical records and tape storage. While volumes in our Global RIM Business segment were relatively steady in 2022 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 data privacy regulations, and that we assume higher liability under our contracts. 

We have an established privacy compliance framework 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 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.

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.

Our reputation for providing secure information storage to customers is critical to the success of our business. Our reputation or 
brand, and specifically, the trust our customers place in us, could be negatively impacted in the event of perceived or actual failures 
by us to store information securely. Although we seek to prevent and detect attempts by unauthorized users to gain access to our 
IT systems, and incur significant costs to do so, our IT and network infrastructure has in the past been and may in the future be 
vulnerable to attacks by hackers, including state-sponsored organizations with significant financial and technological resources, 
breaches due to employee error, fraud or malice or other disruptions (including, but not limited to, computer viruses and other 
malware, denial of service, and ransomware), which may involve a privacy breach requiring us to notify regulators, clients or 
employees and enlist identity theft protection. Moreover, until we have migrated businesses we acquire onto our IT systems or 
ensured compliance with our information technology security standards, we have in the past and may in the future face additional 
risks because of the continued use of predecessor IT systems. We have outsourced, and expect to continue to outsource, certain 
support services, including cloud storage systems and cloud computing services, to third parties, which has in the past and may in 
the future subject our IT and other sensitive information to additional risk. In addition, the continuation of remote work 
arrangements following the COVID-19 pandemic has increased and could further increase our cybersecurity risks. A successful 
breach of the security of our IT systems could lead to theft or misuse of our customers’ proprietary or confidential information or our 
employees’ personal information and result in third party claims against us, regulatory penalties, and reputational harm. Although 
we maintain insurance coverage for various cybersecurity risks, there is no guarantee that all costs or losses incurred will be fully 
insured. Damage to our reputation could make us less competitive, which could negatively impact our business, financial condition 
and results of operations.

Failure to successfully integrate acquired businesses could negatively impact our balance sheet and results of operations.

Strategic acquisitions are an important element of our growth strategy and the success of any acquisition we make depends in part 
on our ability to integrate the acquired business and realize anticipated synergies. The process of integrating acquired businesses, 
particularly in new markets or for new offerings, may involve unforeseen difficulties and may require a disproportionate amount of 
our management’s attention and our financial and other resources.

                                                                                                                                                                                                                                  Part I

For example, the success of our significant acquisitions depends, in large part, on our ability to realize the anticipated benefits, 
including cost savings or revenue acceleration from combining the acquired businesses with ours. To realize these anticipated 
benefits, we must be able to successfully integrate our business and the acquired businesses, and this integration is complex and 
time-consuming. We may encounter challenges in the integration process including the following:

• challenges and difficulties associated with managing our larger, more complex, company;

• conforming standards, controls, procedures and policies, business cultures and compensation and benefits structures between 

the two businesses;

• consolidating corporate and administrative infrastructures;

• coordinating geographically dispersed organizations;

•

retaining critical acquired talent;

• potential unknown liabilities and unforeseen expenses or delays associated with an acquisition; and

• our ability to deliver on our strategy going forward.

Further, our acquisitions subject us to liabilities (including tax liabilities) that may exist at an acquired company, some of which may 
be unknown. Although we and our advisors conduct due diligence on the businesses we acquire, there can be no guarantee that 
we are aware of all liabilities of an acquired company. These liabilities, and any additional risks and uncertainties related to an 
acquired company not known to us or that we may deem immaterial or unlikely to occur at the time of the acquisition, could 
negatively impact our future business, financial condition and results of operations.

We can give no assurance that we will ultimately be able to effectively integrate and manage the operations of any acquired 
business or realize anticipated synergies. The failure to successfully integrate the cultures, operating systems, procedures and 
information technologies of an acquired business could have a material adverse effect on our financial condition and results of 
operations.

Our future growth depends in part upon our ability to continue to effectively manage and execute on revenue management.

Over the past several years, our organic revenue growth has been positively impacted by our ability to effectively introduce, expand 
and monitor revenue management. If we are not able to continue and effectively manage pricing, our results of operations could be 
adversely affected and we may not be able to execute on our strategic growth plan.

Our customer contracts may not always limit our liability and may sometimes contain terms that could lead to disputes in contract 
interpretation.

Our customer contracts typically contain standardized provisions limiting our liability regarding the services we perform and the loss 
or destruction of, or damage to, records, information, or other items stored with us; however, some of our contracts with large 
customers and some of the contracts assumed in our acquisitions contain no such limits or contain non-standard limits. We can 
provide no assurance that our limitation of liability provisions will be enforceable in all instances or, if enforceable, that they would 
otherwise protect us from liability. In the past, we have had relatively few disputes with our customers regarding the terms of their 
customer contracts, and most disputes to date have not been material, but we can provide no assurance that we will not have 
material disputes in the future. Moreover, as we expand our operations into new businesses, including digital solutions and the 
storage of valuable items, and respond to customer demands for higher limitation of liability, our exposure to contracts with higher 
or no limitations of liability and disputes with customers over contract interpretation may increase. Although we maintain a 
comprehensive insurance program, we can provide no assurance that we will be able to maintain insurance policies on acceptable 
terms or with high enough coverage amounts to cover losses to us in connection with customer contract disputes.

Part I

As a global company, we are subject to the unique risks of operating in many countries.

As of December 31, 2022, we operated in 60 countries. The global nature of our business and our growth strategy, which includes 
continued acquisitions and investments in countries where we do not currently operate, is subject to numerous risks, including:

•

•

fluctuations of currency exchange rates in the markets in which we operate;

the impact of laws and regulations that apply to us in countries where we operate; in particular, we are subject to sanctions and 
anti-corruption laws, such as the Foreign Corrupt Practices Act and the United Kingdom Bribery Act, and, although we have 
implemented internal controls, policies and procedures and training to deter prohibited practices, our employees, partners, 
contractors or agents may violate or circumvent such policies and the law; 

• costs and difficulties associated with managing global operations, including cross border sales;

•

the volatility of certain economies in which we operate;

• political uncertainties and changes in the global political climate or other global events, such as trade wars or global pandemics, 
which may create additional risk in relation to our global operations, which may become more pronounced as we consolidate 
operations across countries and need to move data across borders; 

•

the risk that business partners upon whom we depend for technical assistance or management and acquisition expertise in 
some markets will not perform as expected;

• difficulties attracting and retaining local management and key employees to operate our business in certain countries; and

• cultural differences and differences in business practices and operating standards, as well as risks and challenges in expanding 

into countries where we have no prior operational experience.

If we fail to meet our commitment to transition to more renewable and sustainable sources of energy, it may negatively impact our 
ability to attract and retain customers, employees and investors who focus on this commitment. 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.

We have made a commitment to prioritize sustainable energy practices, reduce our carbon footprint and transition to more 
renewable and sustainable sources of energy, particularly in our Global Data Center Business. We have made progress towards 
reducing our carbon footprint, but if we are not successful in continuing this reduction or if our customers, employees and investors 
are not satisfied with our sustainability efforts, it may negatively impact our ability to attract and retain customers, employees and 
investors who focus on this commitment. This could negatively impact our results of operations and the trading of our stock.

Furthermore, changes in environmental laws in any jurisdiction in which we operate could increase compliance costs or impose 
limitations on our operations. For example, our emergency generators at our data centers are subject to regulations and permit 
requirements governing air pollutants, and the heating, ventilation and air conditioning and fire suppression systems at some of our 
data centers and data management locations may include ozone-depleting substances that are subject to regulation. While 
environmental regulations do not normally impose material costs upon operations at our facilities, unexpected events, equipment 
malfunctions, human error and changes in law or regulations, among other factors, could result in unexpected costs, which could 
be material.

Our use of joint ventures could expose us to additional risks and liabilities, including our reliance on joint venture partners who may 
have economic and business interests that are inconsistent with our business interests, our lack of sole decision-making authority, 
and disputes between us and our joint venture partners.

As part of our growth strategy, particularly in connection with our international and data center expansion, we currently, and may in 
the future, co-invest with third parties using joint ventures. These joint ventures can result in our holding non-controlling interests in, 
or having shared responsibility for managing the affairs of, a property or portfolio of properties, business, partnership, joint venture 
or other entity. As a result, in connection with our pursuit or entrance into any such joint venture, we may be subject to additional 
risks, including:

• our ability to sell our interests in the joint venture may be limited by the joint venture agreement;  

• we may not have the right to exercise sole decision-making authority regarding the properties, business, partnership, joint 

venture or other entity;

•

if our partners become bankrupt or fail to fund their share of required capital contributions, we may choose or be required to 
contribute unplanned capital; and

• our partners may have economic, tax or other interests or goals that are inconsistent with our interests or goals, and that could 

affect our ability to negotiate satisfactory joint venture terms, to operate the property or business or maintain our qualification for 
taxation as a REIT.

Each of these factors may result in returns on these investments being less than we expect or in losses, and our financial and 
operating results may be adversely affected.

Significant costs or disruptions at our data centers could adversely affect our business, financial condition and results of operations.

Our Global Data Center Business depends on providing customers with highly reliable facilities, power infrastructure and 
operations solutions, and we will need to retain and hire qualified personnel to manage our data centers. Service interruptions or 
significant equipment damage could result in difficulty maintaining service level commitment obligations that we owe to certain of 
our customers. Service interruptions or equipment damage may occur at one or more of our data centers because of numerous 
factors, including: human error; equipment failure; physical, electronic and cyber security breaches; fire, hurricane, flood, 
earthquake and other natural disasters; water damage; fiber cuts; extreme temperatures; power loss or telecommunications failure; 
war, terrorism and any related conflicts or similar events worldwide; and sabotage and vandalism. 

We purchase significant amounts of electricity and water for cooling from suppliers that are subject to environmental laws, 
regulations and permit requirements. These environmental requirements are subject to material change, which could result in 
increases in our suppliers’ compliance costs that may be passed through to us or otherwise constrain the availability of such 
resources. In addition, climate change may increase the likelihood that our data centers are affected by some of these factors.

While these risks could impact our overall business, they could have a more significant impact on our Global Data Center 
Business, where we have service level commitment obligations to certain of our customers. As a result, service interruptions or 
significant equipment damage at our data centers could result in difficulty maintaining service level commitments to these 
customers and potential claims related to such failures. Because our data centers are critical to many of our customers’ 
businesses, service interruptions or significant equipment damage at our data centers could also result in lost profits or other 
indirect or consequential damages to our customers, which could in turn result in contractual liability to our customers or impair our 
ability to obtain and retain customers, which would adversely affect both our ability to generate revenue and our results of 
operations.

We also rely on third party telecommunications carriers to provide internet connectivity to our customers. These carriers may elect 
not to offer or to restrict their services within our data centers or may elect to discontinue such services. Furthermore, carriers may 
face business difficulties, which could affect their ability to provide telecommunications services or the quality of such services. If 
connectivity is interrupted or terminated, our financial condition and results of operations may be adversely affected. Events such 
as these may also impact our reputation as a data center provider which could adversely affect our results of operations.

Our Global Data Center Business is susceptible to regional costs of power, power shortages, planned or unplanned power outages 
and limitations on the availability of adequate power resources. We rely on third parties to provide power to our data centers. We 
are therefore subject to an inherent risk that such third parties may fail to deliver such power in adequate quantities or on a 
consistent basis. If the power delivered to our data centers is insufficient or interrupted, we would be required to provide power 
through the operation of our on-site generators, generally at a significantly higher operating cost. Additionally, global fluctuations in 
the price of power can increase the cost of energy, and we may be limited in our ability to, or may not always choose to, pass these 
increased costs on to our customers. 

We face additional risks in expanding our Global Data Center Business, including the significant amount of capital required.

Expanding our Global Data Center Business requires significant capital commitments. In addition, we may be required to commit 
significant operational and financial resources in connection with the organic growth of our Global Data Center Business, generally 
12 to 18 months in advance of securing customer contracts, and we may not have enough customer demand to support these data 
centers when they are built. We are currently experiencing rising construction costs which reflect the increase in cost of labor and 
raw materials, as well as supply chain and logistical challenges. Additional or unexpected disruptions to our supply chain or 
continued inflationary pressures could significantly affect the cost or timing of our planned expansion projects and interfere with our 
ability to meet commitments to customers who have contracted for space in new data centers under construction. 

All construction related data center projects require us to carefully select and rely on the experience of one or more design firms, 
general contractors, and associated subcontractors during the design and construction process. Should a design firm, general 
contractor, significant subcontractor, or key supplier experience financial or operational problems during the design or construction 
process, fail to perform properly or at all, we could experience significant delays, increased costs to complete the project, and other 
negative impacts to the expected return on our committed capital. 

There can be no assurance we will have sufficient customer demand to support the data centers we have acquired, or that we will 
not be adversely affected by the risks noted above under "Significant costs or disruptions at our data centers could adversely affect 
our business, financial condition and results of operations", which could make it difficult for us to realize expected returns on our 
investments, if any.

Our ALM business may be subject to additional risks, including those related to its client and geographic concentration,  
government trade policies, and macroeconomic conditions. 

A significant portion of the revenue from our ALM business is derived from a limited number of clients and tied to cyclical projects 
involving the decommissioning and destruction of IT assets and the disposition of components of such assets to purchasers in 
concentrated geographies. Though we generally enter into long-term contracts with such clients, the volume of work we perform for 
specific clients may vary over the life of each contract due to various factors including changes in client behavior or macroeconomic 
conditions impacting the availability of new IT assets in the marketplace. There can be no assurance that we will be able to retain 
our current volumes, existing clients or that, if we were to lose one or more of our significant clients, we would be able to replace 
such clients with clients that generate a comparable amount of revenue. Further, many of the purchasers of the decommissioned IT 
asset components are geographically concentrated, particularly within mainland China. If governments enact trade policies that 
restrict the export of IT assets into China or other markets in which we sell decommissioned IT asset components, or increase the 
enforcement of such policies, then the revenue from the sale of these assets may be negatively impacted. Additionally, uncertain 
macroeconomic conditions, particularly within mainland China, may reduce our purchasers’ demand for the IT asset components 
that we sell, thereby reducing our revenues and earnings.

Failure to comply with certain regulatory and contractual requirements under our United States Government contracts could 
adversely affect our revenues, operating results and financial position and reputation.

Having the United States Government as a customer subjects us to certain regulatory and contractual requirements. Failure to 
comply with these requirements could subject us to investigations, price reductions, up to treble damages, and civil penalties. 
Noncompliance with certain regulatory and contractual requirements could also result in us being suspended or debarred from 
future United States Government contracting. We may also face private derivative securities claims because of adverse 
government actions. Any of these outcomes could have a material adverse effect on our revenues, operating results, financial 
position and reputation.

We may be subject to certain costs and potential liabilities associated with the real estate required for our business.

As of December 31, 2022, we operated approximately 1,400 facilities worldwide, including approximately 600 in the United States, 
and face special risks attributable to the real estate we own or lease. Such risks include:

• acquisition and occupancy costs that make it difficult to meet anticipated margins and difficulty locating suitable facilities due to a 

relatively small number of available buildings having the desired characteristics in some real estate markets; 

•

increases in rent expense and property taxes as a result of the increasing demand for industrial real estate;

• uninsured losses or damage to our storage facilities due to an inability to obtain full coverage on a cost-effective basis for some 
casualties, such as fires, hurricanes and earthquakes, or any coverage for certain losses, such as losses from riots or terrorist 
activities;

•

•

inability to use our real estate holdings effectively and costs associated with vacating or consolidating facilities if the demand for 
physical storage were to diminish;

liability under environmental laws for the costs of investigation and cleanup of contaminated real estate owned or leased by us, 
whether or not (i) we know of, or were responsible for, the contamination, or (ii) the contamination occurred while we owned or 
leased the property; and

• costs of complying with fire protection and safety standards.

Some of our current 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 an environmental review of all of our properties, including those we have acquired. We therefore may be potentially 
liable for environmental costs like those discussed above and may be unable to sell, rent, mortgage or use contaminated real 
estate owned or leased by us. 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.

Unexpected events, including those resulting from climate change or geopolitical events, could disrupt our operations and 
adversely affect our reputation and results of operations.

Unexpected events, including fires or explosions at our facilities, war or other military conflict, terrorist activities, natural disasters 
such as earthquakes and wildfires, unplanned power outages, supply disruptions, failure of equipment or systems, and severe 
weather events, such as droughts, heat waves, hurricanes, and flooding, could adversely affect our reputation and results of 
operations through physical damage to our facilities and equipment and through physical damage to, or disruption of, local 
infrastructure. During the past several years we have seen an increase in the frequency and intensity of severe weather events and 
we expect this trend to continue due to climate change. Some of our key facilities worldwide are vulnerable to severe weather 
events, and global weather pattern changes may also pose long-term risks of physical impacts to our business. Our customers rely 
on us to securely store and timely retrieve their critical information, and, while we maintain disaster recovery and business 
continuity plans that would be implemented in these situations, these unexpected events could result in customer service 
disruption, physical damage to one or more key operating facilities and the information stored in those facilities, the temporary 
closure of one or more key operating facilities or the temporary disruption of information systems, each of which could negatively 
impact our reputation and results of operations. In addition, these unexpected events could negatively impact our reputation if such 
events result in adverse publicity, governmental investigations or litigation or if customers do not otherwise perceive our response 
to be adequate. 

Fluctuations in commodity prices may affect our operating revenues and results of operations.

Our operating revenues and results of operations are impacted by significant changes in commodity prices. In particular, our secure 
shredding operations generate revenue from the sale of shredded paper for recycling. Further, significant declines in the cost of 
paper may continue to negatively impact our revenues and results of operations, and increases in other commodity prices, 
including steel, may negatively impact our results of operations.

Failure to manage and adequately implement our new IT systems could negatively affect our business.

We rely on IT infrastructure, including hardware, networks, software, people and processes, to provide information to support 
assessments and conclusions about our operating performance. We are in the process of upgrading a number of our IT systems, 
including consolidating our existing finance operations platforms, and we face risks relating to these transitions. For example, we 
may incur greater costs than we anticipate training our personnel on the new systems, we may experience service disruptions or 
errors in accurately capturing data or retaining our records, and we may be delayed in meeting our various reporting obligations. 
There can be no assurance that we will manage our IT systems and implement these new systems as planned or that we will do so 
without disruptions to our operations, which could have an adverse effect on our business, financial condition, results of operations 
and cash flows.

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.

As of December 31, 2022, our total long-term debt was approximately $10,650.3 million, stockholders equity was approximately 
$636.7 million and we had cash and cash equivalents of approximately $141.8 million. Our indebtedness could have important 
consequences to our current and potential investors. These risks include:

•

•

•

•

•

•

•

•

inability to satisfy our obligations with respect to our various debt instruments;

inability to make borrowings to fund future working capital, capital expenditures and strategic growth opportunities, including 
acquisitions, further organic development of, and investment into, our Global Data Center Business, ALM and Fine Arts 
businesses and other service offerings, and other general corporate requirements, including possible required repurchases, 
redemptions or prepayments of our various indebtedness;

limits on our distributions to stockholders; in this regard if these limits prevented us from satisfying our REIT distribution 
requirements, we could fail to remain qualified for taxation as a REIT or, if these limits do not jeopardize our qualification for 
taxation as a REIT but do nevertheless prevent us from distributing 100% of our REIT taxable income, we will be subject to 
federal corporate income tax, and potentially a nondeductible excise tax, on the retained amounts;

limits on future borrowings under our existing or future credit arrangements, which could affect our ability to pay our 
indebtedness or to fund our other liquidity needs;

inability to generate sufficient funds to cover required interest payments;

restrictions on our ability to refinance our indebtedness on commercially reasonable terms;

limits on our flexibility in planning for, or reacting to, changes in our business and the information management services industry; 
and

inability to adjust to adverse economic conditions that could place us at a disadvantage to our competitors with less debt and 
who, therefore, may be able to take advantage of opportunities that our indebtedness prevents us from pursuing.

Certain of our indebtedness, including indebtedness under our credit agreement, is paid at floating interest rates, and as a result, 
our interest expense or the cost of our debt may increase due to rising interest rates or changes to benchmark rates.

Restrictive debt covenants may limit our ability to pursue our growth strategy.

Our Credit Agreement and our indentures contain covenants restricting or limiting our ability to, among other things:

•

incur additional indebtedness;

• pay dividends or make other restricted payments;

• make asset dispositions;

• create or permit liens;

• sell, transfer or exchange assets;

• guarantee certain indebtedness;

• make acquisitions and other investments; and

• enter into partnerships and joint ventures.

These restrictions and our long-term commitment to reduce our leverage ratio may adversely affect our ability to pursue our 
acquisition and other growth strategies, including our strategic growth plan.

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.

Upon the occurrence of a "change of control", as defined in our indentures, we will be required to offer to repurchase all of our 
outstanding senior notes. However, it is possible that we will not have sufficient funds at the time of a change of control to make the 
required repurchase of any outstanding notes or that restrictions in our Credit Agreement will not allow such repurchases. Certain 
important corporate events, however, such as leveraged recapitalizations that would increase the level of our indebtedness, would 
not constitute a "change of control" under our indentures.

Iron Mountain Incorporated ("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.

IMI is a holding company; substantially all of its assets consist of the equity in its subsidiaries, and substantially all of its operations 
are conducted by its direct and indirect consolidated subsidiaries. As a result, its ability to make payments on its debt obligations 
will be dependent upon the receipt of sufficient funds from its subsidiaries, whose ability to distribute funds may be limited by local 
capital requirements, joint venture structures and other applicable restrictions. However, our various debt obligations are 
guaranteed, on a joint and several and full and unconditional basis, by IMI’s U.S. subsidiaries that represent the substantial 
majority of its U.S. operations.

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.

We have elected to be taxed as a REIT for federal income tax purposes beginning with our 2014 taxable year. We believe that our 
organization and method of operation comply with the rules and regulations promulgated under the Internal Revenue Code of 
1986, as amended (the "Code"), such that we will continue to qualify for taxation as a REIT. However, we can provide no assurance 
that we will remain qualified for taxation as a REIT. We also have invested in a subsidiary that intends to elect to be taxed as a 
REIT and therefore must independently satisfy all REIT qualification requirements. If such subsidiary REIT were to fail to qualify as 
a REIT, it may cause us to fail to remain qualified for taxation as a REIT. If we fail to remain qualified for taxation as a REIT, 
including as a result of a cascading failure of any subsidiary REIT to remain qualified as a REIT, we will be subject to federal 
income taxation at corporate income tax rates unless certain relief provisions apply.

Qualification for taxation as a REIT involves the application of highly technical and complex provisions of the Code to our 
operations as well as various factual determinations concerning matters and circumstances not entirely within our control. There 
are limited judicial or administrative interpretations of applicable REIT provisions of the Code.

If, in any taxable year, we fail to remain qualified for taxation as a REIT and are not entitled to relief under the Code:

• we will not be allowed a deduction for distributions to stockholders in computing our taxable income;

• we will be subject to federal and state income tax on our taxable income at regular corporate income tax rates; and

• we would not be eligible to elect REIT status again until the fifth taxable year that begins after the first year for which we failed to 

qualify for taxation as a REIT.

Any such corporate tax liability could be substantial and would reduce the amount of cash available for other purposes. If we fail to 
remain qualified for taxation as a REIT, we may need to borrow additional funds or liquidate some investments to pay any 
additional tax liability. Accordingly, funds available for investment and distributions to stockholders could be reduced.

                                                                                                                                                                                                                                  Part I

As a REIT, failure to make required distributions would subject us to federal corporate income tax.

We expect to continue paying regular quarterly distributions; however, the amount, timing and form of our regular quarterly 
distributions will be determined, and will be subject to adjustment, by our board of directors. To remain qualified for taxation as a 
REIT, we are generally required to distribute at least 90% of our REIT taxable income (determined without regard to the dividends 
paid deduction and excluding net capital gain) each year, or in limited circumstances, the following year, to our stockholders. 
Generally, we expect to distribute all or substantially all of our REIT taxable income. If our cash available for distribution falls short 
of our estimates, we may be unable to maintain distributions that approximate our REIT taxable income and may fail to remain 
qualified for taxation as a REIT. In addition, our cash flows from operations may be insufficient to fund required distributions as a 
result of differences in timing between the actual receipt of income and the payment of expenses and the recognition of income and 
expenses for federal income tax purposes, or the effect of nondeductible expenditures.

To the extent that we satisfy the 90% distribution requirement but distribute less than 100% of our REIT taxable income, we will be 
subject to federal corporate income tax on our undistributed taxable income. In addition, we will be subject to a 4% nondeductible 
excise tax on our undistributed taxable income if the actual amount that we distribute to our stockholders for a calendar year is less 
than the minimum amount specified under the Code.

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.

In order to satisfy our REIT distribution requirements and maintain our qualification and taxation as a REIT, or to fund capital 
expenditures, future growth and expansion initiatives, we may need to borrow funds, sell assets or raise equity, even if our financial 
condition or the then-prevailing market conditions are not favorable for these borrowings, sales or offerings. Furthermore, the REIT 
distribution requirements and our commitment to investors on dividend growth may result in increasing our financing needs to fund 
capital expenditures, future growth and expansion initiatives, which would increase our indebtedness. An increase in our 
outstanding debt could lead to a downgrade of our credit ratings, which could negatively impact our ability to access credit markets. 
Further, certain of our current debt instruments limit the amount of indebtedness we and our subsidiaries may incur. Additional 
financing, therefore, may be unavailable, more expensive or restricted by the terms of our outstanding indebtedness. For a 
discussion of risks related to our substantial level of indebtedness, see "Risks Related to Our Indebtedness".

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.

To remain qualified for taxation as a REIT, we must satisfy tests concerning, among other things, the sources of our income, the 
nature and diversification of our assets and the amounts we distribute to our stockholders. Thus, compliance with these tests may 
require us to refrain from certain activities and may hinder our ability to make certain attractive investments, including the purchase 
of non-REIT qualifying operations or assets, the expansion of non-real estate activities, and investments in the businesses to be 
conducted by our taxable REIT subsidiaries ("TRSs"), and, to that extent, limit our opportunities and our flexibility to change our 
business strategy and execute on our strategic growth plan. This may restrict our ability to acquire certain businesses, enter into 
joint ventures or acquire minority interests of companies. Furthermore, acquisition opportunities in domestic and international 
markets may be adversely affected if we need or require the target company to comply with some REIT requirements prior to 
closing.

We conduct a significant portion of our business activities, including our information management services businesses and several 
of our international operations, through domestic and foreign TRSs. Under the Code, no more than 20% of the value of the assets 
of a REIT may be represented by securities of one or more TRSs. Similar rules apply to other nonqualifying assets. These 
limitations may affect our ability to make additional investments in non-REIT qualifying operations or assets or in international 
operations through TRSs.

If we fail to comply with specified asset ownership tests applicable to REITs as measured at the end of any calendar quarter, we 
generally must correct such failure within 30 days after the end of the applicable calendar quarter or qualify for statutory relief 
provisions to avoid losing our qualification for taxation as a REIT. As a result, we may be required to liquidate assets or to forgo our 
pursuit of otherwise attractive investments or executing on portions of our strategic growth plan. These actions may 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 ability to receive distributions from our TRSs is limited by the rules with which we must comply to maintain our qualification for 
taxation as a REIT. In particular, at least 75% of our gross income for each taxable year as a REIT must be derived from real 
estate, which generally includes gross income from providing customers with secure storage space or colocation or wholesale data 
center space. Consequently, no more than 25% of our gross income may consist of dividend income from our TRSs and other 
nonqualifying types of income. Thus, our ability to receive distributions from our TRSs may be limited, which may impact our ability 
to fund distributions to our stockholders using cash flows from our TRSs. Specifically, if our TRSs become highly profitable, we 
might become limited in our ability to receive net income from our TRSs in an amount required to fund distributions to our 
stockholders commensurate with that profitability.

IRON MOUNTAIN 2022 FORM 10-K

Part I

In addition, a significant amount of our income and cash flows from our TRSs is generated from our international operations. In 
many cases, there are local withholding taxes and currency controls that may impact our ability or willingness to repatriate funds to 
the United States to help satisfy REIT distribution requirements.

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.

Our operations include an extensive use of TRSs. The net income of our TRSs is not required to be distributed to us, and income 
that is not distributed to us generally is not subject to the REIT income distribution requirement. However, there may be limitations 
on our ability to accumulate earnings in our TRSs and the accumulation or reinvestment of significant earnings in our TRSs could 
result in adverse tax treatment. In particular, if the accumulation of cash in our TRSs causes (i) the fair market value of our 
securities in our TRSs to exceed 20% of the fair market value of our assets or (ii) the fair market value of our securities in our TRSs 
and other nonqualifying assets to exceed 25% of the fair market value of our assets, then we will fail to remain qualified for taxation 
as a REIT. Further, a substantial portion of our operations are conducted overseas, and a material change in foreign currency rates 
could also affect the value of our foreign holdings in our TRSs, negatively impacting our ability 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.

Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes, including 
taxes on any undistributed income, and state, local or foreign income, franchise, property and transfer taxes. In addition, we could 
in certain circumstances be required to pay an excise or penalty tax, which could be significant in amount, in order to utilize one or 
more relief provisions under the Code to maintain our qualification for taxation as a REIT.

A portion of our business is conducted through TRSs because certain of our business activities could generate nonqualifying REIT 
income as currently structured and operated. The income of our domestic TRSs will continue to be subject to federal and state 
corporate income taxes. In addition, our international assets and operations will continue to be subject to taxation in the foreign 
jurisdictions where those assets are held or those operations are conducted. Any of these taxes would decrease our earnings and 
our available cash.

We will also be subject to a federal corporate level income tax at the highest regular corporate income tax rate on gain recognized 
from a sale of a REIT asset where our basis in the asset is determined by reference to the basis of the asset in the hands of a C 
corporation (such as an asset that we hold in one of our qualified REIT subsidiaries ("QRSs") following the liquidation or other 
conversion of a former TRS). This tax is generally applicable to any disposition of such an asset during the five-year period after 
the date we first owned the asset as a REIT asset, to the extent of the built-in-gain based on the fair market value of such asset on 
the date we first held the asset as a REIT asset. In addition, any depreciation recapture income that we recognize because of 
accounting method changes that we make in connection with our acquisition activities will be fully subject to this tax.

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.

The REIT provisions of the Code limit our ability to hedge assets, liabilities, revenues and expenses. Generally, income from 
hedging transactions that we enter into to manage risk of interest rate changes with respect to borrowings made or to be made by 
us to acquire or carry real estate assets and income from certain currency hedging transactions related to our non-United States 
operations, as well as income from qualifying counteracting hedges, do not constitute "gross income" for purposes of the REIT 
gross income tests. To the extent that we enter into other types of hedging transactions, the income from those transactions is likely 
to be treated as nonqualifying income for purposes of the REIT gross income tests. As a result of these rules, we may need to limit 
our use of advantageous hedging techniques or implement those hedges through our TRSs. This could increase the cost of our 
hedging activities because our TRSs would be subject to tax on income or gains resulting from hedges entered into by them and 
may expose us to greater risks associated with changes in interest rates or exchange rates than we would otherwise want to bear. 
In addition, hedging losses in any of our TRSs generally will not provide any tax benefit, except for being carried forward for 
possible use against future income or gain in the TRSs.

Distributions payable by REITs generally do not qualify for preferential tax rates.

Dividends payable by United States corporations to noncorporate stockholders, such as individuals, trusts and estates, are 
generally eligible for reduced United States federal income tax rates applicable to "qualified dividends". Distributions paid by REITs 
generally are not treated as "qualified dividends" under the Code, and the reduced rates applicable to such dividends do not 
generally apply. However, for tax years beginning before 2026, REIT dividends paid to noncorporate stockholders that meet 
specified holding period requirements are generally taxed at an effective tax rate lower than applicable ordinary income tax rates 
due to the availability of a deduction under the Code for specified forms of income from passthrough entities. More favorable rates 
will nevertheless continue to apply to regular corporate "qualified" dividends, which may cause some investors to perceive that an 
investment in a REIT is less attractive than an investment in a non-REIT entity that pays dividends, thereby reducing the demand 
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.

In order for us to remain qualified for taxation as a REIT, no more than 50% of the value of outstanding shares of our capital stock 
may be owned, beneficially or constructively, by five or fewer individuals at any time during the last half of each taxable year. In 
addition, rents from "affiliated tenants" will not qualify as qualifying REIT income if we own 10% or more by vote or value of the 
customer, whether directly or after application of attribution rules under the Code. Subject to certain exceptions, our certificate of 
incorporation prohibits any stockholder from owning, beneficially or constructively, more than (i) 9.8% in value of the outstanding 
shares of all classes or series of our capital stock or (ii) 9.8% in value or number, whichever is more restrictive, of the outstanding 
shares of any class or series of our capital stock. We refer to these restrictions collectively as the "ownership limits" and we 
included them in our certificate of incorporation to facilitate our compliance with REIT tax rules. The constructive ownership rules 
under the Code are complex and may cause the outstanding stock owned by a group of related individuals or entities to be deemed 
to be constructively owned by one individual or entity. As a result, the acquisition of less than 9.8% of our outstanding common 
stock (or the outstanding shares of any class or series of our capital stock) by an individual or entity could cause that individual or 
entity or another individual or entity to own constructively in excess of the relevant ownership limits. Any attempt to own or transfer 
shares of our common stock or of any of our other capital stock in violation of these restrictions may result in the shares being 
automatically transferred to a charitable trust or may be void. Even though our certificate of incorporation contains the ownership 
limits, there can be no assurance that these provisions will be effective to prevent our qualification for taxation as a REIT from 
being jeopardized, including under the affiliated tenant rule. Furthermore, there can be no assurance that we will be able to monitor 
and enforce the ownership limits. If the restrictions in our certificate of incorporation are not effective and, as a result, we fail to 
satisfy the REIT tax rules described above, then, absent an applicable relief provision, we will fail to remain qualified for taxation as 
a REIT.

In addition, the ownership and transfer restrictions could delay, defer or prevent a transaction or a change in control that might 
involve a premium price for our stock or otherwise be in the best interest of our stockholders. As a result, the overall effect of the 
ownership and transfer restrictions may be to render more difficult or discourage any attempt to acquire us, even if such acquisition 
may be favorable to the interests of our stockholders. 

Legislative or other actions affecting REITs could have a negative effect on us or our stockholders.

At any time, the federal or state income tax laws governing REITs, the administrative interpretations of those laws, or local laws 
impacting our REIT structure for our international operations may be amended. Federal, state and local tax laws are constantly 
under review by persons involved in the legislative process, the IRS, the United States Department of the Treasury ("Treasury") 
and state and local taxing authorities. Changes to the tax laws, regulations and administrative interpretations or local laws 
governing our international operations, which may have retroactive application, could adversely affect us. In addition, some of 
these changes could have a more significant impact on us as compared to other REITs due to the nature of our business and our 
substantial use of TRSs, particularly non-United States TRSs, or how we have structured our operations outside the United States 
to comply with REIT qualification requirements. We cannot predict with certainty whether, when, in what forms, or with what 
effective dates, the tax laws, regulations, administrative interpretations or local laws applicable to us may be changed or if such 
laws would impact our ability to remain qualified for taxation as a REIT or the costs of doing so. 

GENERAL RISK FACTORS

Our cash distributions are not guaranteed and may fluctuate.

As a REIT, we are generally required to distribute at least 90% of our REIT taxable income to our stockholders. Furthermore, we 
are committed to growing our dividends, and have stated this publicly.

Our board of directors, in its sole discretion, will determine, on a quarterly basis, the amount of cash to be distributed to our 
stockholders based on a number of factors including, but not limited to, our results of operations, cash flow and capital 
requirements, economic conditions, tax considerations, borrowing capacity and other factors, including debt covenant restrictions 
that may impose limitations on cash payments, future acquisitions and divestitures, any stock repurchase program and general 
market demand for our space and related services. Consequently, our distribution levels may fluctuate and we may not be able to 
meet our public commitments with respect to dividend growth.

Our business could be adversely impacted if there are deficiencies in our disclosure controls and procedures or internal control 
over financial reporting.

The design and effectiveness of our disclosure controls and procedures and internal control over financial reporting may not 
prevent all errors, misstatements or misrepresentations. While management will continue to review the effectiveness of our 
disclosure controls and procedures and internal control over financial reporting, there can be no guarantee that our internal control 
over financial reporting will be effective in accomplishing all control objectives all of the time. Furthermore, our disclosure controls 
and procedures and internal control over financial reporting with respect to entities that we do not control or manage may be 
substantially more limited than those we maintain with respect to the subsidiaries that we have controlled or managed over the 
course of time. Deficiencies, including any material weakness, in our internal control over financial reporting which may occur in the 
future could result in misstatements of our results of operations, restatements of our financial statements, a decline in our stock 
price, or otherwise materially adversely affect our business, reputation, results of operations, financial condition or liquidity.

We face competition for customers.

We compete with multiple businesses in all geographic areas where we operate; our current or potential customers may choose to 
use those competitors instead of us. In addition, if we are successful in winning customers from competitors, the process of moving 
their stored records into our facilities is often costly and time consuming. We also compete, in some of our business lines, with our 
current and potential customers’ internal storage and information management services capabilities and their cloud-based 
alternatives. These organizations may not begin or continue to use us for their future storage and information management service 
needs.

The performance of our businesses relies on our ability to attract, develop, and retain talented personnel, while controlling our labor 
costs.

We are highly dependent on skilled and qualified personnel to operate our businesses. Furthermore, our contracts with the United 
States Government require us to use personnel with security clearances, and we may not be successful or may experience delays 
in attracting, training or retaining qualified personnel with the requisite skills or security clearances. The failure to attract and retain 
qualified employees or to effectively control our labor costs could negatively affect our competitive position and operating results. 
Our ability to control labor costs and attract qualified personnel is subject to numerous external factors, including prevailing wages, 
labor shortages, the impact of legislation or regulations governing wages and hours, labor relations, immigration, healthcare and 
other benefits, other employment-related costs and the hiring practices of our competitors.

ITEM 1B. UNRESOLVED STAFF COMMENTS.

Business (20) and Corporate and Other (57). These facilities contain a total of approximately 96.8 million square feet of space. A

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.

Our total building utilization and total racking utilization as of December 31, 2022 in Records Management and Data Management 
are as follows:

See Note 2.j. to Notes to Consolidated Financial Statements included in this Annual Report for information regarding our minimum 
annual lease commitments as a lessee.

See Schedule III—Schedule of Real Estate and Accumulated Depreciation in this Annual Report for information regarding the cost,

The following table sets forth a summary of the lease expirations for leases in place related to our Global Data Center Business, for 
which we are the lessor, as of December 31, 2022. The information set forth in the table assumes that tenants exercise no renewal 
options and all early termination rights.

OVERVIEW

PROJECT MATTERHORN

Part II

In September 2022, we announced Project Matterhorn, our global program designed to accelerate the growth of our business. 
Project Matterhorn investments will focus on transforming our operating model to a global operating model. Project Matterhorn 
will focus 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 will be investing to accelerate growth and to capture a greater share of 
the large, global addressable markets in which we operate. We expect to incur approximately $150.0 million in costs annually 
related to Project Matterhorn from 2023 through 2025. 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 our growth initiatives. Total costs related to Project Matterhorn during 
the year ended December 31, 2022 were approximately $41.9 million and are included in Restructuring and other transformation 
in our Consolidated Statement of Operations. There were no Restructuring and other transformation costs related to Project 
Matterhorn for the year ended December 31, 2021.

ACQUISITION OF ITRENEW

On January 25, 2022, in order to expand our ALM operations, we acquired an approximately 80% interest in Intercept Parent, Inc. 
("ITRenew"). From January 25, 2022, we consolidate 100% of the revenues and expenses associated with this business. ITRenew 
is presented in Corporate and Other and primarily operates in the United States. See Acquisitions within the Liquidity and Capital 
Resources section below for additional information.

PROJECT SUMMIT 

In October 2019, we announced Project Summit, our global program designed to better position us for future growth and 
achievement of our strategic objectives. As of December 31, 2021, we completed Project Summit. As a result of the program, we 
simplified our global structure, rebalanced resources to focus on higher growth areas, realigned our management structure to 
create a more dynamic, agile organization, made investments to enhance the customer experience and leveraged new technology 
solutions that enabled us to modernize our service delivery model and more efficiently utilize our fleet, labor and real estate. Project 
Summit improved annual Adjusted EBITDA (as defined below) by approximately $375.0 million exiting 2021, of which 
approximately $50.0 million and $160.0 million were realized in 2022 and 2021, respectively.

The implementation of Project Summit resulted in total restructuring costs of approximately $450.0 million that primarily consisted 
of: (i) employee severance costs; (ii) internal costs associated with the development and implementation of Project Summit 
initiatives; (iii) professional fees, primarily related to third party consultants who assisted with the design and execution of various 
initiatives as well as project management activities and (iv) system implementation and data conversion costs. Total restructuring 
costs included in Restructuring and other transformation in our Consolidated Statements of Operations for the year ended 
December 31, 2021 were $206.4 million. As Project Summit was completed as of December 31, 2021, there were no restructuring 
costs for Project Summit for the year ended December 31, 2022.

DIVESTMENTS AND DECONSOLIDATIONS

OSG RECORDS MANAGEMENT (EUROPE) LIMITED DECONSOLIDATION

On March 24, 2022, as a result of our loss of control, we deconsolidated the businesses included in our acquisition of OSG 
Records Management (Europe) Limited, excluding Ukraine ("OSG Deconsolidation"). We recognized a loss of approximately 
$105.8 million associated with the deconsolidation to Other (income) expense, net in the first quarter of 2022 representing the 
difference between the net asset value prior to the deconsolidation and the subsequent remeasurement of the retained investment 
to a fair value of zero. These businesses represented approximately $44.9 million of total revenues and $7.2 million of total net 
income for the year ended December 31, 2021.

INTELLECTUAL PROPERTY MANAGEMENT BUSINESS DIVESTMENT

On June 7, 2021, we sold our Intellectual Property Management ("IPM") business, which we predominantly operated in the United 
States, for total gross consideration of approximately $215.4 million (the "IPM Divestment"). As a result of the IPM Divestment, we 
recorded a gain on sale of approximately $179.0 million to Other (income) expense, net during the year ended December 31, 2021, 
representing the excess of the fair value of the consideration received over the sum of the carrying value of the IPM business. Our 
IPM business represented approximately $14.2 million and $6.8 million of total revenues and total net income, respectively, for the 
year ended December 31, 2021.

GENERAL

RESULTS OF OPERATIONS - KEY TRENDS 

• We have experienced steady volume in our Global RIM Business segment, with organic storage rental revenue growth driven 

primarily by revenue management. We expect organic storage rental revenue growth to benefit from revenue management and 
volume to be relatively stable in the near term.

• Our organic service revenue growth is primarily due to increases in our service activity. We expect organic service revenue 

growth in 2023 to benefit from our new and existing digital offerings, as well as our traditional services.

• We expect continued total revenue and Adjusted EBITDA growth in 2023 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.

• We expect the impact of a stronger US dollar to create headwinds on reported total revenue and Adjusted EBITDA growth in 

2023 against prior periods.

Our revenues consist of storage rental revenues as well as 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 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) destruction services, consisting primarily of (i) secure shredding of sensitive documents and the 
subsequent sale of shredded paper for recycling, the price of which can fluctuate from period to period, and (ii) the 
decommissioning, data erasure, processing and disposition or sale of IT hardware and component assets; (3) digital solutions, 
including the scanning, imaging and document conversion services of active and inactive records, and consulting services; and (4) 
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. 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. While customers continue to store their records and tapes with us, they are less likely than they have been in the 
past to retrieve records for research and other purposes, thereby reducing service activity levels.

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), 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 and data processing, travel, professional 
fees, bad debts, training, office equipment and supplies.

IRON MOUNTAIN 2022 FORM 10-K

Table of Contents

Part II

Cost of sales (excluding depreciation and amortization) and Selling, general and administrative expenses for the year ended 
December 31, 2022 consists of the following:

COST OF SALES

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

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; and
the levels of utilization of these properties.

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.

The expansion of our international businesses has impacted the major cost of sales components and selling, general and 
administrative expenses.

• Our international operations are more labor intensive relative to revenue than our operations in North America and, 

therefore, labor costs are a higher percentage of international operational revenue.

• The overhead structure of our expanding international operations has generally not achieved the same level of overhead 

leverage as our North American operations, which may result in an increase in selling, general and administrative expenses 
as a percentage of revenue as our international operations become a larger percentage of our consolidated results.

Our depreciation and amortization charges result primarily from depreciation related to storage systems, which include racking 
structures, buildings, building and leasehold improvements and computer systems hardware and software. Amortization relates 
primarily to customer and supplier relationship intangible assets, contract fulfillment costs and data center lease-based intangible 
assets. Both depreciation and amortization are impacted by the timing of acquisitions. 

Our consolidated revenues and expenses are subject to the net effect of foreign currency translation related to our operations 
outside the United States. It is difficult to predict the future fluctuations of foreign currency exchange rates and how those 
fluctuations will impact our Consolidated Statements of Operations. As a result of the relative size of our international operations, 
these fluctuations may be material on individual balances. Our revenues and expenses from our international operations are 
generally denominated in the local currency of the country in which they are derived or incurred. Therefore, the impact of currency 
fluctuations on our operating income and operating margin is partially mitigated. In order to provide a framework for assessing how 
our underlying businesses performed excluding the effect of foreign currency fluctuations, we compare the percentage change in 
the results from one period to another period in this report using constant currency presentation. The constant currency growth 
rates are calculated by translating the 2021 results at the 2022 average exchange rates. Constant currency growth rates are a non-
GAAP measure.

NON-GAAP MEASURES

ADJUSTED EBITDA

Part II

Adjusted EBITDA is defined as net income (loss) before interest expense, net, provision (benefit) for income taxes, depreciation 
and amortization (inclusive of our share of Adjusted EBITDA from our unconsolidated joint ventures), and excluding certain items 
we do not believe to be indicative of our core operating results, specifically:

EXCLUDED

• Acquisition and Integration Costs (as defined below)

• Other (income) expense, net

• Restructuring and other transformation

• Stock-based compensation expense

•

(Gain) loss on disposal/write-down of property, plant and 
equipment, net (including real estate)

Adjusted EBITDA Margin is calculated by dividing Adjusted EBITDA by total revenues. We also show Adjusted EBITDA and 
Adjusted EBITDA Margin for each of our reportable segments under "Results of Operations – Segment Analysis" below.

Adjusted EBITDA excludes both interest expense, net and the provision (benefit) for income taxes. These expenses are associated 
with our capitalization and tax structures, which we do not consider when evaluating the operating profitability of our core 
operations. Adjusted EBITDA also does not include depreciation and amortization expenses, in order to eliminate the impact of 
capital investments, which we evaluate by comparing capital expenditures to incremental revenue generated and as a percentage 
of total revenues. Adjusted EBITDA and Adjusted EBITDA Margin should be considered in addition to, but not as a substitute for, 
other measures of financial performance reported in accordance with accounting principles generally accepted in the United States 
of America ("GAAP"), such as operating income, net income (loss) or cash flows from operating activities (as determined in 
accordance with GAAP).

FFO (NAREIT) AND FFO (NORMALIZED)

Funds from operations ("FFO") is defined by the National Association of Real Estate Investment Trusts as net income (loss) 
excluding depreciation on real estate assets, losses and gains on sale of real estate, net of tax, and amortization of data center 
leased-based intangibles ("FFO (Nareit)"). We calculate our FFO measures, including FFO (Nareit), adjusting for our share of 
reconciling items from our unconsolidated joint ventures. FFO (Nareit) does not give effect to real estate depreciation because 
these amounts are computed, under GAAP, to allocate the cost of a property over its useful life. Because values for well-
maintained real estate assets have historically increased or decreased based upon prevailing market conditions, we believe that 
FFO (Nareit) provides investors with a clearer view of our operating performance. Our most directly comparable GAAP measure to 
FFO (Nareit) is net income (loss).

We modify FFO (Nareit), as is common among REITs seeking to provide financial measures that most meaningfully reflect their 
particular business ("FFO (Normalized)"). Our definition of FFO (Normalized) excludes certain items included in FFO (Nareit) that 
we believe are not indicative of our core operating results, specifically:

EXCLUDED
• Acquisition and Integration Costs

• Stock-based compensation expense

• Restructuring and other transformation

• Non-cash amortization related to derivative instruments

CRITICAL ACCOUNTING ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based upon our Consolidated Financial 
Statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to 
make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and 
related disclosure of contingent assets and liabilities at the date of the financial statements and for the period then ended. On an 
ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, actuarial estimates, current 
conditions and various other assumptions that we believe to be reasonable under the circumstances. These estimates form the 
basis for making judgments about the carrying values of assets and liabilities and are not readily apparent from other sources. 
Actual results may differ from these estimates. The following should be read in conjunction with Note 2 to Notes to Consolidated 
Financial Statements included in this Annual Report, which provides a summary of our significant accounting policies. Our critical 
accounting estimates include the following, which are listed in no particular order: 

REVENUE RECOGNITION 

Revenue is recognized when or as control of promised goods or services is transferred to the customer, in an amount that reflects 
the consideration we expect to be entitled to in exchange for those goods or services. See Note 2.s. to Notes to Consolidated 
Financial Statements included in this Annual Report for additional details on our revenue recognition policies. Revenue for all our 
lines of business, with the exception of storage revenues in our Global Data Center Business (which is subject to leasing 
guidance), is recognized in accordance with Accounting Standards Codification ("ASC") 606, Revenue from Contracts with 
Customers ("ASC 606"), the application of which requires that we make estimates and judgements that may affect the amount and 
timing of revenue we recognize. 

We have determined that the majority of our contracts contain series performance obligations which qualify to be recognized under 
a practical expedient available in ASC 606 known as the "right to invoice". This determination allows variable consideration in such 
contracts to be allocated to and recognized in the period to which the consideration relates, which is typically the period in which it 
is billed, rather than requiring estimation of variable consideration at the inception of the contract. Revenue from product sales, the 
significant majority of which are shred paper and IT asset sales, is recognized at the point in time at which control transfers to the 
customer, which is generally upon shipment. 

From time to time, we make payments to entities that are also customers under a revenue contract. These payments are primarily 
comprised of (i) Customer Inducements (as defined in Note 2.m. to Notes to Consolidated Financial Statements included in this 
Annual Report) and (ii) payments to customers of our ALM business under revenue sharing arrangements for the remarketing of 
the customer's disposed IT assets. Customer Inducements do not represent payments for a distinct service, and, as such, are 
treated as a reduction of the transaction price over periods ranging from one to 10 years. Payments for disposed IT assets are for a 
distinct good and, as such, are expensed as cost of goods sold in the period the revenue share is known or estimable.

Contract Fulfillment Costs (as defined in Note 2.s. to Notes to Consolidated Financial Statements included in this Annual Report) 
are generally amortized over a three year term, which we have determined is consistent with the transfer of the underlying 
performance obligations to which the assets relate. Different determinations on term length would result in differences in the 
amount and timing of amortization expense recognized.

ACCOUNTING FOR ACQUISITIONS

Part of our growth strategy has been to acquire businesses. The purchase price of each acquisition is determined after due 
diligence of the target business, market research, strategic planning and the forecasting of expected future results and synergies. 
Estimated future results and expected synergies are subject to revisions as we integrate each acquisition and attempt to leverage 
resources. 

Accounting for acquisitions of a business has resulted in the capitalization of the cost in excess of the estimated fair value of the 
net assets acquired in each of these acquisitions as goodwill. We estimate the fair values of the assets acquired in each acquisition 
as of the date of acquisition and these estimates are subject to adjustment based on the final assessments of the fair value of 
intangible assets (primarily customer and supplier relationship and data center lease-based intangible assets), property, plant and 
equipment (primarily building, building improvements, leasehold improvements, data center infrastructure and racking structures), 
operating leases, contingencies and income taxes (primarily deferred income taxes). See Note 3 to Notes to Consolidated 
Financial Statements included in this Annual Report for a description of recent acquisitions. 

Determining the fair values of the net assets acquired requires management’s judgment and often involves the use of assumptions 
with respect to future cash inflows and outflows, discount rates and market data, among other items. As it relates to our data center 
acquisitions, the fair values of the net assets acquired requires management’s judgment and often involves the use of assumptions 
with respect to (i) certain economic costs (as described more fully in Note 2.m. to Notes to Consolidated Financial Statements 
included in this Annual Report) avoided by acquiring a data center operation with active tenants that would have otherwise been 
incurred if the data center operation was purchased vacant, (ii) market rental rates and (iii) expectations of lease renewals and 
extensions. Due to the inherent uncertainty of future events, actual values of net assets acquired could be different from our 
estimated fair values and could have a material impact on our financial statements.

Part II

Of the net assets acquired in our acquisitions, the fair value of owned buildings, including building improvements, customer and 
supplier relationship and data center lease-based intangible assets, racking structures and operating leases are generally the most 
common and most significant. For significant acquisitions or acquisitions involving new markets or new products, we generally use 
third parties to assist us in estimating the fair value of owned buildings, including building improvements, customer and supplier 
relationship and lease-based intangible assets and market rental rates for acquired operating leases. For acquisitions that are not 
significant or do not involve new markets or new products, we generally use third parties to assist us in estimating the fair value of 
acquired owned buildings, including building improvements, and market rental rates for acquired operating leases. When not using 
third party appraisals of the fair value of acquired net assets, the fair value of acquired customer and supplier relationship intangible 
assets, above and below market in-place operating leases, and racking structures is determined internally. We use discounted cash 
flow models to determine the fair value of customer and supplier relationship intangible assets, which requires a significant amount 
of judgment by management, including estimating expected lives of the relationships, expected future cash flows and discount 
rates. The fair value of above and below market in-place operating leases is determined internally using a discounted cash flow 
model, utilizing the difference in cash flows between the contractual lease payments over the remaining lease term and estimated 
market rental rates on comparable assets at the time of the acquisition. The fair value of acquired racking structures is determined 
internally by taking current estimated replacement cost at the date of acquisition for the quantity of racking structures acquired, 
discounted to take into account the quality (e.g. age, material and type) of the racking structures. We determine the fair value of 
tangible data center assets using an estimated replacement cost at the date of acquisition, then discounting for age, economic and 
functional obsolescence.

The fair value of the Deferred Purchase Obligation associated with the ITRenew Transaction (each as defined below) was 
determined utilizing a Monte-Carlo simulation model and takes into account our forecasted projections as it relates to the 
underlying performance of the business. The Monte-Carlo simulation model incorporates assumptions as to expected gross profits 
over the applicable achievement period, including adjustments for the volatility of timing and amount of the associated revenue and 
costs, as well as discount rates that account for the risk of the underlying arrangement and overall market risks.

Our estimates of fair value are based upon assumptions believed to be reasonable at that time but which are inherently uncertain 
and unpredictable. Assumptions may be incomplete or inaccurate, and unanticipated events and circumstances may occur, which 
may affect the accuracy of such assumptions. Total customer and supplier relationship intangible assets acquired in our 2022 
acquisitions were approximately $491.3 million.

IMPAIRMENT OF TANGIBLE AND INTANGIBLE ASSETS 

ASSETS SUBJECT TO DEPRECIATION OR AMORTIZATION 

We review long-lived assets and finite-lived intangible assets for impairment whenever events or changes in circumstances indicate 
the carrying amount of such assets may not be recoverable. Examples of events or circumstances that may be indicative of 
impairment include, but are not limited to:

• A significant decrease in the market price of an asset;

• A significant change in the extent or manner in which a long-lived asset is being used or in its physical condition;

• A significant adverse change in legal factors or in the business climate that could affect the value of the asset;

• An accumulation of costs significantly greater than the amount originally expected for the acquisition or construction of an asset;

• A current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast 

that demonstrates continuing losses associated with the use of a long-lived asset; and

• A current expectation that, more likely than not, an asset will be sold or otherwise disposed of significantly before the end of its 

previously estimated useful life.

If events indicate the carrying value of such assets may not be recoverable, recoverability of these assets is determined by 
comparing the sum of the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying 
amount. The operations are generally distinguished by the business segment and geographic region in which they operate. If it is 
determined that we are unable to recover the carrying amount of the assets, the long-lived assets are written down, on a pro rata 
basis, to fair value. Fair value is determined based on discounted cash flows or appraised values, depending upon the nature of the 
assets.

We did not record impairment charges for any of our long-lived assets or finite-lived intangibles during the years ended December 
31, 2022 and 2021.

GOODWILL AND OTHER INDEFINITE-LIVED INTANGIBLE ASSETS NOT SUBJECT TO 
AMORTIZATION

Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment, or more frequently if 
impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not 
amortized. See Note 2.l. to Notes to Consolidated Financial Statements included in this Annual Report for additional details on our 
goodwill and other indefinite-lived intangible assets policies.  

We have selected October 1 as our annual goodwill impairment review date. We have performed our annual goodwill impairment 
review as of October 1, 2022 and 2021. We concluded that as of October 1, 2022 and 2021, goodwill was not impaired.

Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2022 were as follows:

• North American Records and Information Management reporting 

• Asia, Australia and New Zealand Records and Information 

unit ("North America RIM")

Management reporting unit ("APAC RIM")

• Europe and South Africa Records and Information Management 

• Entertainment Services

reporting unit ("ESA RIM")

• Middle East, North Africa and Turkey Records and Information 

Management reporting unit ("MENAT RIM")

• Latin America Records and Information Management reporting 

unit ("Latin America RIM")

• Global Data Center

• Fine Arts

• ALM

See Note 2.l. to Notes to Consolidated Financial Statements included in this Annual Report for a description of our reporting units.

Based on our goodwill impairment analysis as of October 1, 2022, all of our reporting units had estimated fair values exceeding 
their carrying values by greater than 20%. Our Global Data Center and ALM reporting units had an estimated fair value that 
exceeded their respective carrying values by approximately 20.4% and 28.0%, respectively. The Global Data Center and ALM 
reporting units represented approximately $995.9 million, or 20.4%, of our consolidated goodwill balance at December 31, 2022. 
The following is a summary of the Global Data Center and ALM reporting units including the goodwill balance (in thousands), the 
percentage by which the fair value of the reporting units exceeded their carrying values and certain key assumptions used by us in 
determining the fair value of the reporting units as of October 1, 2022:

For purposes of our goodwill impairment analysis, the term "capital expenditures" includes both growth investment and recurring capital expenditures. The capital 
expenditure assumptions in our goodwill impairment analysis for our Global Data Center reporting unit include significant growth investment in the next three years. 

Terminal growth rates are applied after year 10 of our discounted cash flow analysis.

The fair values of our reporting units are generally determined using a combined approach based on the present value of future 
cash flows (the "Discounted Cash Flow Model") and market multiples (the "Market Approach"). There are inherent uncertainties and 
judgments involved when determining the fair value of the reporting units for purposes of our annual goodwill impairment testing. 
The following includes supplemental information to the table above for the Global Data Center and ALM reporting units where the 
estimated fair value exceeded its carrying value by approximately 20.4% and 28.0%, respectively, as of October 1, 2022. The fair 
value of our Global Data Center reporting unit was determined using a combined Discounted Cash Flow Model and Market 
Approach, while the fair value of our ALM reporting unit was determined using a Discounted Cash Flow Model approach. The 
success of these businesses and the achievement of certain key assumptions developed by management and used in the 
Discounted Cash Flow Model are contingent upon various factors including, but not limited to, (i) achieving growth from existing 
customers, (ii) sales to new customers, (iii) increased market penetration and (iv) accurately timing the capital investments related 
to expansions.

GLOBAL DATA CENTER

Part II

Our Global Data Center Business operates in 21 data centers across 19 global markets, either directly or through unconsolidated 
joint ventures. We provide enterprise-class data center facilities and hyperscale-ready capacity to protect mission-critical assets 
and ensure the continued operation of our customers’ IT infrastructure with secure, reliable and flexible data center options. Data 
centers are highly specialized and secure assets that serve as centralized repositories of server, storage and network equipment. 
They are capital intensive and designed to provide the space, power, cooling and network connectivity necessary to efficiently 
operate mission-critical IT equipment. The demand for data center infrastructure is being driven by many factors, but most 
importantly by significant growth in data as well as an increased demand for outsourcing. In order to attract and retain customers, 
as well as sustain growth in our existing and new markets, we must have the capability to tailor our facilities and invest capital to 
meet our customers’ needs. Our estimate of fair value reflects the expected growth in each of our data center markets along with 
the corresponding capital investments required to meet demand. 

ALM

Our ALM business provides hyperscale and corporate IT infrastructure managers with services and solutions that enable the 
decommissioning, data erasure, processing and disposition or sale of IT hardware and component assets. ALM services are 
enabled by: (i) secure logistics, chain of custody and complete asset traceability practices; (ii) environmentally-responsible asset 
processing and recycling; and (iii) data sanitization and asset refurbishment services that enable value recovery through asset 
remarketing. The assumptions we used in determining fair value reflect the ongoing and anticipated expansion of these services, 
the timing of reopening of supply chains due to closures associated with border restrictions, particularly in mainland China, in 
connection with the COVID-19 pandemic, the maintenance and further development of the supplier relationships required to 
expand this business and meet customer demand and decommissioning schedules of our supplier's IT hardware and component 
assets, as well as associated market pricing and demand for such assets at that time. Our ALM business is substantially comprised 
of the ITRenew Transaction entered into during the first quarter of 2022; therefore, we would expect, at this time, that the fair value 
of this reporting unit would closely approximate its carrying value.

KEY ASSUMPTIONS

Key factors that could reasonably be expected to have a negative impact on the estimated fair value of these reporting units and 
potentially result in impairment charges include, but are not limited to: (i) a deterioration in general economic conditions, (ii) 
significant adverse changes in regulatory factors or in the business climate, and (iii) adverse actions or assessment by regulators, 
all of which could result in adverse changes to the key assumptions used in valuing the reporting units. The inability to meet the 
assumptions used in the Discounted Cash Flow Model and Market Approach for each of the reporting units, or future adverse 
market conditions not currently known, could lead to a fair value that is less than the carrying value in any one of our reporting 
units. 

The Discounted Cash Flow Model incorporates significant assumptions including future revenue growth rates, operating margins, 
discount rates and capital expenditures. The Market Approach requires us to make assumptions related to Adjusted EBITDA 
multiples. Changes in economic and operating conditions impacting these assumptions or changes in multiples could result in 
goodwill impairments in future periods. In conjunction with our annual goodwill impairment reviews, we reconcile the sum of the 
valuations of all of our reporting units to our market capitalization as of such dates.

Although we believe we have sufficient historical and projected information available to us to test for goodwill impairment, it is 
possible that actual results could differ from the estimates used in our impairment tests. Of the key assumptions that impact the 
goodwill impairment test, the expected future cash flows and discount rate are among the most sensitive and are considered to be 
critical assumptions, as changes to these estimates could have an effect on the estimated fair value of each of our reporting units. 
We have assessed the sensitivity of these assumptions on each of our reporting units as of October 1, 2022.

We noted that, based on the estimated fair value of these reporting units determined as of 
October 1, 2022:

• a hypothetical decrease of 10% in the expected annual future cash flows of these reporting 
units, with all other assumptions unchanged, would have decreased the estimated fair value 
of these reporting units as of October 1, 2022 by a range of approximately 9.8% to 10.4% 
but would not, however, have resulted in the carrying value of any of these reporting units 
exceeding their estimated fair value;

• a hypothetical increase of 100 basis points in the discount rate, with all other assumptions 
unchanged, would have decreased the estimated fair value of these reporting units as of 
October 1, 2022 by a range of approximately 3.7% to 10.1% but would not, however, have 
resulted in the carrying value of any of these reporting units exceeding their estimated fair 
value.

Global Data Center

We noted that, as of October 1, 2022, the estimated fair value of the reporting unit:

• exceeds its carrying value by approximately 20.4%.

Accordingly, any significant negative change in either the expected annual future cash flows of 
the reporting unit or the discount rate may result in the carrying value of the reporting unit 
exceeding its estimated fair value.

ALM

We noted that, as of October 1, 2022, the estimated fair value of the reporting unit:

• exceeds its carrying value by approximately 28.0%.

Accordingly, any significant negative change in either the expected annual future cash flows of 
the reporting unit or the discount rate may result in the carrying value of the reporting unit 
exceeding its estimated fair value.

At December 31, 2022, no factors were identified that would alter the conclusions of our October 1, 2022 goodwill impairment 
analysis. In making this assessment, we considered a number of factors including operating results, business plans, anticipated 
future cash flows, transactions and marketplace data. There are inherent uncertainties related to these factors and our judgment in 
applying them to the analysis of goodwill impairment.

INCOME TAXES

As a REIT, we are generally permitted to deduct from our federal taxable income the dividends we pay to our stockholders. The 
income represented by such dividends is not subject to federal taxation at the entity level but is taxed, if at all, at the stockholder 
level. The income of our domestic TRSs, which hold our domestic operations that may not be REIT-compliant as currently operated 
and structured, is subject, as applicable, to federal and state corporate income tax. In addition, we and our subsidiaries continue to 
be subject to foreign income taxes in other jurisdictions in which we have business operations or a taxable presence, regardless of 
whether assets are held or operations are conducted through subsidiaries disregarded for federal income tax purposes or TRSs. 
We will also be subject to a separate corporate income tax on any gains recognized on the sale or disposition of any asset 
previously owned by a C corporation during a five-year period after the date we first owned the asset as a REIT asset that are 
attributable to "built-in gains" with respect to that asset on that date. We will also be subject to a built-in gains tax on our 
depreciation recapture recognized into income as a result of accounting method changes in connection with our acquisition 
activities. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income tax at regular corporate income 
tax rates. Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and foreign taxes on 
our income and property in addition to taxes owed with respect to our TRS operations. In particular, while state income tax regimes 
often parallel the federal income tax regime for REITs, many states do not completely follow federal rules and some do not follow 
them at all. See Note 10 to Notes to Consolidated Financial Statements included in this Annual Report for additional details on our 
tax policies.

Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences 
of temporary differences between the tax and financial reporting bases of assets and liabilities and for loss and credit 
carryforwards. We measure deferred tax assets and liabilities using enacted tax rates expected to be applied to taxable income in 
the years in which those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred 
tax assets and liabilities as a result of a change in tax rates is recognized in income in the period that the change is enacted. 
Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not standard as 
defined in GAAP. Valuation allowances would be reversed as a reduction to the provision for income taxes if related deferred tax 
assets are deemed realizable based on changes in facts and circumstances relevant to the recoverability of the asset.

Part II

At December 31, 2022, we have federal net operating loss carryforwards of $63.5 million, which can be carried forward indefinitely, 
of which $57.1 million is expected to be realized to reduce future federal taxable income. We have assets for foreign net operating 
losses of $81.9 million, with various expiration dates (and in some cases no expiration date), subject to a valuation allowance of 
approximately 56.0%. If actual results differ unfavorably from certain of our estimates used, we may not be able to realize all or part 
of our net deferred income tax assets and additional valuation allowances may be required. Although we believe our estimates are 
reasonable, no assurance can be given that our estimates reflected in the tax provisions and accruals will equal our actual results. 
These differences could have a material impact on our income tax provision and operating results in the period in which such 
determination is made.

The evaluation of an uncertain tax position is a two-step process. The first step is a recognition process whereby we determine 
whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals 
or litigation processes, based on the technical merits of the position. The second step is a measurement process whereby a tax 
position that meets the more likely than not recognition threshold is calculated to determine the amount of benefit to recognize in 
the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being 
realized upon ultimate settlement.

We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various 
tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of 
additional assessments by tax authorities and provide for these matters as appropriate. As of both December 31, 2022 and 2021, 
we had approximately $27.8 million of reserves related to uncertain tax positions. The reversal of these reserves will be recorded 
as a reduction of our income tax provision if sustained. Although we believe our tax estimates are appropriate, the final 
determination of tax audits and any related litigation could result in changes in our estimates.

During 2021, as a result of the enactment of a tax law and the closing of various acquisitions, we concluded that it is no longer our 
intention to reinvest our undistributed earnings of our foreign TRSs indefinitely outside the United States. As a REIT, future 
repatriation of incremental undistributed earnings of our foreign subsidiaries will not be subject to federal or state income tax, with 
the exception of foreign withholding taxes. However, such future repatriations may require distributions to our stockholders in 
accordance with REIT distribution rules, and any such distribution may then be taxable, as appropriate, at the stockholder level. We 
expect to provide for foreign withholding taxes on the current and future earnings of all of our foreign subsidiaries as the result of 
such reassessment.

STORAGE RENTAL REVENUES • organic storage rental revenue growth driven by increased volume in faster growing 
markets and our Global Data Center Business segment and revenue management;
• a 0.4% increase in total global volume excluding deconsolidations (also excluding 

acquisitions, total global volume increased 0.4%); and

• a decrease of $81.5 million due to foreign currency exchange rate fluctuations.

SERVICE REVENUES

• organic service revenue growth reflecting increased service activity levels;

• an increase of $213.1 million due to our acquisition of ITRenew; and

• a decrease of $49.5 million due to foreign currency exchange rate fluctuations.

Primary factors influencing the change in reported Selling, general and administrative expenses for the year ended December 31, 
2022 compared to the year ended December 31, 2021 include the following: 

• an increase in general, administrative and other expenses, driven by recent acquisitions, higher wages and benefits, employee 

related costs, information technology costs and professional fees, partially offset by benefits from Project Summit; 

• an increase in sales, marketing and account management expenses, driven by higher compensation expense, primarily 

reflecting increased wages and benefits and recent acquisitions; and

• a decrease of $24.5 million due to foreign currency exchange rate fluctuations. 

DEPRECIATION AND AMORTIZATION

Our depreciation and amortization charges result primarily from depreciation related to storage systems, which include racking 
structures, buildings, building and leasehold improvements and computer systems hardware and software. Amortization relates 
primarily to customer and supplier relationship intangible assets, contract fulfillment costs and data center lease-based intangible 
assets. Both depreciation and amortization are impacted by the timing of acquisitions.

Depreciation expense increased $13.9 million, or 3.0%, on a reported dollar basis for the year ended December 31, 2022 
compared to the year ended December 31, 2021. See Note 2.i. to Notes to Consolidated Financial Statements included in this 
Annual Report for additional information regarding the useful lives over which our property, plant and equipment is depreciated. 

Amortization expense increased $33.3 million, or 15.4%, on a reported dollar basis for the year ended December 31, 2022 
compared to the year ended December 31, 2021, primarily related to the amortization of intangible assets acquired as part of the 
acquisition of ITRenew. 

ACQUISITION AND INTEGRATION COSTS

Acquisition and Integration Costs for the years ended December 31, 2022 and 2021 was approximately $47.7 million and $12.8 
million, respectively. 

RESTRUCTURING AND OTHER TRANSFORMATION

Restructuring and other transformation costs for the years ended December 31, 2022 and 2021 were approximately $41.9 million 
and $206.4 million, respectively, and related to operating expenses associated with the implementation of Project Matterhorn in 
2022 and Project Summit in 2021.

OTHER EXPENSES, NET

INTEREST EXPENSE, NET

Interest expense, net increased $70.1 million to $488.0 million for the year ended December 31, 2022 from $418.0 million for the 
year ended December 31, 2021. The increase is primarily due to higher average debt outstanding during the year ended December 
31, 2022 compared to the prior year period as well as an increase in our weighted average interest rate. Our weighted average 
interest rate, inclusive of the fees associated with our outstanding letters of credit, was 5.1% and 4.7% at December 31, 2022 and 
2021, respectively. See Note 7 to Notes to Consolidated Financial Statements included in this Annual Report for additional

FOREIGN CURRENCY TRANSACTION (GAINS) LOSSES, NET 

We recorded net foreign currency transaction gains of $61.7 million in the year ended December 31, 2022, based on period-end 
exchange rates. These gains resulted primarily from the impact of changes in the exchange rate of the Euro and the British pound 
sterling against the United States dollar compared to December 31, 2021 on our intercompany balances with and between certain 
of our subsidiaries.

OTHER, NET

Part II

Other, net for the year ended December 31, 2022 consists primarily of (i) a gain of approximately $93.6 million associated with the 
remeasurement of the Deferred Purchase Obligation (as defined below) to the present value of our best estimate of fair value and 
(ii) a gain of approximately $35.8 million associated with the Clutter Transaction (as defined below), partially offset by (iii) a loss of 
approximately $105.8 million associated with the OSG Deconsolidation (as defined in Note 4) and (iv) losses on our equity method 
investments. Other, net for the year ended December 31, 2021 consists primarily of (i) a gain of approximately $179.0 million 
associated with our IPM Divestment and (ii) a gain of approximately $20.3 million associated with the loss of control and related 
deconsolidation, as of May 18, 2021, of one of our wholly owned Netherlands subsidiaries, for which we had value-added tax 
liability exposure that was recorded in 2019, partially offset by (iii) losses on our equity method investments.

PROVISION (BENEFIT) FOR INCOME TAXES

Our effective tax rates for the years ended December 31, 2022 and 2021 were 11.0% and 28.0%, respectively. Our effective tax 
rate is subject to variability in the future due to, among other items: (i) changes in the mix of income between our QRSs and our 
TRSs, as well as among the jurisdictions in which we operate; (ii) tax law changes; (iii) volatility in foreign exchange gains and 
losses; (iv) the timing of the establishment and reversal of tax reserves; (v) our ability to utilize net operating losses that we 
generate and (vi) the taxability or deductibility of significant transactions.

The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate were:

YEAR ENDED DECEMBER 31,

2022
The benefits derived from the dividends paid deduction of $82.6 million 
and the differences in the tax rates to which our foreign earnings are 
subject of $22.2 million. In addition, there were gains and losses 
recorded in Other (income) expense, net and Gain (loss) on disposal/
write-down of property, plant and equipment, net during the period for 
which there were insignificant tax impacts. 

2021

The benefit derived from the dividends paid deduction of $8.2 million 
which was offset by (i) the impact of differences in the tax rates at 
which our foreign earnings are subject to, resulting in a tax provision 
of $9.9 million, and (ii) foreign withholding taxes of $23.7 million, 
which were either paid during the year or accrued, for the deferred tax 
liability for the U.S. tax impact of undistributed earnings of foreign 
TRSs that are no longer intended to be permanently reinvested 
outside the United States. 

As a REIT, we are entitled to a deduction for dividends paid, resulting in a substantial reduction of federal income tax expense. As a 
REIT, substantially all of our income tax expense will be incurred based on the earnings generated by our foreign subsidiaries and 
our domestic TRSs.

We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various 
tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of 
additional assessments by tax authorities and provide for these matters as appropriate. Although we believe our tax estimates are 
appropriate, the final determination of tax audits and any related litigation could result in changes in our estimates.

LIQUIDITY AND CAPITAL RESOURCES

GENERAL

We expect to meet our short-term and long-term cash flow requirements through cash generated from operations, cash on hand, 
borrowings under our Credit Agreement (as defined below) and proceeds from monetizing a small portion of our total industrial real 
estate assets, as well as other potential financings (such as the issuance of debt). Our cash flow requirements, both in the near 
and long term, include, but are not limited to, capital expenditures, the repayment of outstanding debt, shareholder dividends, 
potential business acquisitions and normal business operation needs.

PROJECT MATTERHORN

As disclosed above, in September 2022, we announced Project Matterhorn. We estimate that the implementation of Project 
Matterhorn will result in costs of approximately $150.0 million per year from 2023 through 2025. In 2022, we incurred approximately 
$41.9 million of Restructuring and other transformation costs related to Project Matterhorn which 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 our growth initiatives.

A. CASH FLOWS FROM OPERATING ACTIVITIES

For the year ended December 31, 2022, net cash flows provided by operating activities increased by $168.8 million compared to 
the prior year period primarily due to an increase in net income (excluding non-cash charges) of $289.6 million, partially offset by a 
decrease in cash from working capital of $120.8 million, primarily related to the timing of accounts receivable collections and timing 
of accrued expenses.

B. CASH FLOWS FROM INVESTING ACTIVITIES

Our significant investing activities during the year ended December 31, 2022 are highlighted below:

• We paid cash for capital expenditures of $875.4 million. Additional details of our capital spending are included in the "Capital 

Expenditures" section below.

• We paid cash for acquisitions (net of cash acquired) of $803.7 million, primarily funded by the issuance of the 5% Notes due 

2032 (as defined below). 

• We received $170.4 million in proceeds from sales of property, plant and equipment, primarily related to proceeds from sale and 
sale-leaseback transactions. See the Gain on disposal/write-down of property, plant and equipment, net section of Results of 
Operations for further details.

C. CASH FLOWS FROM FINANCING ACTIVITIES

Our significant financing activities for the year ended December 31, 2022 included:

• Net proceeds of $1,356.3 million primarily associated with borrowings under the Revolving Credit Facility and the Accounts 

Receivable Securitization Program.

• Payment of dividends in the amount of $724.4 million on our common stock.

CAPITAL EXPENDITURES

Part II

We present two categories of capital expenditures: (1) Growth Investment Capital Expenditures and (2) Recurring Capital 
Expenditures with the following sub-categories: (i) Data Center; (ii) Real Estate; (iii) Innovation and Other (for Growth Investment 
Capital Expenditures only); and (iv) Non-Real Estate (for Recurring Capital Expenditures only). 

GROWTH INVESTMENT CAPITAL EXPENDITURES:

• Data Center: Expenditures primarily related to investments in the construction of data center facilities (including the acquisition 

of land), as well as investments to drive revenue growth, expand capacity or achieve operational or cost efficiencies.

• Real Estate: Expenditures primarily related to investments in land, buildings, building improvements, leasehold improvements 

and racking structures to grow our revenues, extend the useful life of an asset or achieve operational or cost efficiencies.

•

Innovation and Other: Discretionary capital expenditures for significant new products and services as well as computer 
hardware and software to support new products and services or to achieve operational or cost efficiencies. Restructuring and 
other transformation costs, including Project Matterhorn and Project Summit, and integration costs of acquisitions are also 
included.

RECURRING CAPITAL EXPENDITURES:

• Real Estate: Expenditures primarily related to the replacement of components of real estate assets such as buildings, building 

improvements, leasehold improvements and racking structures.

• Non-Real Estate: Expenditures primarily related to the replacement of containers and shred bins, warehouse equipment, 

fixtures, computer hardware, or third-party or internally-developed software assets that support the maintenance of existing 
revenues or avoidance of an increase in costs.  

• Data Center: Expenditures related to the replacement of equivalent components and overall maintenance of existing data 

center assets.

CREDIT AGREEMENT

Our credit agreement (the "Credit Agreement") consists of a revolving credit facility (the "Revolving Credit Facility"), a term loan A 
(the "Term Loan A") and a term loan B (the "Term Loan B"). On March 18, 2022, we entered into an amendment to the Credit 
Agreement which included the following changes:

(i) extended the maturity date of the Revolving Credit Facility and the Term Loan A from June 3, 2023 to March 18, 2027;

(ii) refinanced and increased the borrowing capacity that IMI and certain of its United States and foreign subsidiaries are 
able to borrow under the Revolving Credit Facility from $1,750.0 million to $2,250.0 million;

(iii) refinanced the existing Term Loan A with a new $250.0 million Term Loan A; and

(iv) increased the net total lease adjusted leverage ratio maximum allowable from 6.5x to 7.0x and removed the net 
secured lease adjusted leverage ratio requirement.

The Revolving Credit Facility enables IMI and certain of its subsidiaries to borrow in United States dollars and (subject to sublimits) 
Canadian dollars in an aggregate outstanding amount not to exceed $2,250.0 million. Additionally, the Credit Agreement permits us 
to incur incremental indebtedness thereunder by adding new term loans or revolving loans or by increasing the principal amount of 
any existing loans thereunder. The Revolving Credit Facility and the Term Loan A are scheduled to mature on March 18, 2027, at 
which point all obligations become due. On March 18, 2022, we borrowed the full amount of the Term Loan A of $250.0 million. The 
Term Loan A is to be paid in quarterly installments in an amount equal to $3.1 million per quarter. IMI’s wholly owned subsidiary, 
Iron Mountain Information Management, LLC ("IMIM"), is the borrower under the Term Loan B, which has a principal amount of 
$700.0 million. The Term Loan B, which matures on January 2, 2026, was issued at 99.75% of par. Principal payments on the Term 
Loan B are to be paid in quarterly installments of $1.8 million.

Part II

IMI and certain subsidiaries of IMI that represent the substantial majority of our operations in the United States, Canada and the 
United Kingdom guarantee all obligations under the Credit Agreement. The interest rate on borrowings under the Revolving Credit 
Facility varies depending on our choice of interest rate benchmark and currency options, plus an applicable margin, which varies 
based on our consolidated leverage ratio. The Term Loan A bears interest at the Secured Overnight Financing Rate ("SOFR") plus 
a credit spread adjustment of 0.1% plus 1.75%. The Term Loan B bears interest at the London Inter-Bank Offered Rate ("LIBOR") 
plus 1.75%. Additionally, the Credit Agreement requires the payment of a commitment fee on the unused portion of the Revolving 
Credit Facility, which fee ranges from 0.2% to 0.3% based on our consolidated leverage ratio. 

As of December 31, 2022, we had $1,072.2 million, $240.6 million and $666.1 million outstanding under the Revolving Credit 
Facility, the Term Loan A and Term Loan B, respectively. At December 31, 2022, we had various outstanding letters of credit totaling 
$3.8 million under the Revolving Credit Facility. The remaining amount available for borrowing under the Revolving Credit Facility 
as of December 31, 2022, which is based on IMI’s leverage ratio, the last 12 months' earnings before interest, taxes, depreciation 
and amortization and rent expense ("EBITDAR"), other adjustments as defined in the Credit Agreement and current external debt, 
was $1,174.0 million (which amount represents the maximum availability as of such date). Available borrowings under the 
Revolving Credit Facility are subject to compliance with our indenture covenants as discussed below. The weighted average 
interest rate in effect under the Revolving Credit Facility as of December 31, 2022 was 6.2%. The interest rates in effect under the 
Term Loan A and the Term Loan B as of December 31, 2022 were 6.2% and 4.8%, respectively.

VIRGINIA CREDIT AGREEMENT

On October 31, 2022, Iron Mountain Data Centers Virginia 4/5 Subsidiary, LLC, a wholly owned subsidiary of Iron Mountain Data 
Centers Virginia 4/5 JV, LP, entered into a credit agreement (the "Virginia Credit Agreement") in order to finance the construction of 
two data center facilities in Virginia. The Virginia Credit Agreement consists of a term loan and a letter of credit facility with the first 
borrowing under the term loan expected to occur in the third quarter of 2023. Borrowings under the Virginia Credit Agreement are 
guaranteed by Iron Mountain Data Centers Virginia 4/5 JV, LP, a special purpose vehicle, and not by IMI or any other subsidiary of 
IMI. We have the option to borrow, in the form of term loans, an aggregate outstanding amount not to exceed approximately $205.0 
million. At December 31, 2022, we had approximately $6.4 million in outstanding letters of credit under the Virginia Credit 
Agreement. The Virginia Credit Agreement requires the payment of a commitment fee on any unused commitments at a rate of 
0.4875%. We have the option to select between various base rates for any given borrowing under the Virginia Credit Agreement, 
and the interest rate and applicable margin on such borrowings vary depending on the chosen base rate. The Virginia Credit 
Agreement is scheduled to mature on October 31, 2025, at which point all obligations will become due. We have two one-year 
options that allow us to extend the maturity date beyond the October 31, 2025 expiration date, subject to the conditions specified in 
the Virginia Credit Agreement, including the lender's consent. As of December 31, 2022, we have no outstanding borrowings under 
the Virginia Credit Agreement.

AUSTRALIAN DOLLAR TERM LOAN

Iron Mountain Australia Group Pty, Ltd. ("IM Australia"), a wholly owned subsidiary of IMI, has an AUD term loan with an original 
principal balance of 350.0 million Australian dollars ("AUD Term Loan"). All indebtedness associated with the AUD Term Loan was 
issued at 99% of par. Principal payments on the AUD Term Loan are to be paid in quarterly installments in an aggregate amount of 
7.7 million Australian dollars per year. 

On March 18, 2022, IM Australia amended its AUD Term Loan to (i) extend the maturity date from September 22, 2022 to 
September 30, 2026 and (ii) decrease the interest rate from BBSY (an Australian benchmark variable interest rate) plus 3.875% to 
BBSY plus 3.625%. The interest rate in effect under the AUD Term Loan was 6.9% as of December 31, 2022.

UK BILATERAL REVOLVING CREDIT FACILITY

Iron Mountain (UK) PLC ("IM UK") and Iron Mountain (UK) Data Centre Limited (collectively, the "UK Borrowers") have a 140.0 
million British pounds sterling Revolving Credit Facility (the "UK Bilateral Revolving Credit Facility") with Barclays Bank PLC. The 
maximum amount permitted to be borrowed under the UK Bilateral Revolving Credit Facility is 140.0 million British pounds sterling, 
which was fully drawn as of December 31, 2022. We have the option to request additional commitments of up to 125.0 million 
British pounds sterling, subject to the conditions specified in the UK Bilateral Revolving Credit Facility. The UK Bilateral Revolving 
Credit Facility is secured by certain properties in the United Kingdom. IMI and subsidiaries of IMI that represent the substantial 
majority of our operations in the United States and the United Kingdom guarantee all obligations under the UK Revolving Credit 
Bilateral Facility.

The UK Bilateral Revolving Credit Facility was previously scheduled to mature on September 24, 2023, at which point all 
obligations were to become due, with the option to extend the maturity date for an additional year, subject to the conditions 
specified in the UK Bilateral Revolving Credit Facility, including the lender’s consent. On September 22, 2022, the UK Borrowers 
exercised their option to extend the maturity date from September 24, 2023 to September 24, 2024. The interest rate in effect 
under the UK Bilateral Revolving Credit Facility was 5.5% as of December 31, 2022.

Part II

ACCOUNTS RECEIVABLE SECURITIZATION PROGRAM

We participate in an accounts receivable securitization program (the "Accounts Receivable Securitization Program") involving 
several of our wholly owned subsidiaries and certain financial institutions. Under the Accounts Receivable Securitization Program, 
certain of our subsidiaries sell substantially all of their United States accounts receivable balances to our wholly owned special 
purpose entities, Iron Mountain Receivables QRS, LLC and Iron Mountain Receivables TRS, LLC (the "Accounts Receivable 
Securitization Special Purpose Subsidiaries"). The Accounts Receivable Securitization Special Purpose Subsidiaries use the 
accounts receivable balances to collateralize loans obtained from certain financial institutions. The Accounts Receivable 
Securitization Special Purpose Subsidiaries are consolidated subsidiaries of IMI. IMIM retains the responsibility of servicing the 
accounts receivable balances pledged as collateral for the Accounts Receivable Securitization Program and IMI provides a 
performance guaranty. The maximum availability allowed is limited by eligible accounts receivable, as defined under the terms of 
the Accounts Receivable Securitization Program.

On June 29, 2022, we amended the Accounts Receivable Securitization Program to (i) increase the maximum borrowing capacity 
from $300.0 million to $325.0 million, with an option to increase the borrowing capacity to $400.0 million, (ii) change the interest 
rate under Accounts Receivable Securitization Program from LIBOR plus 1.0% to SOFR plus 0.95%, with a credit spread 
adjustment of 0.10% and (iii) extend the maturity date from July 1, 2023 to July 1, 2025, at which point all obligations become due. 
As of December 31, 2022, the maximum availability allowed and amount outstanding under the Accounts Receivable Securitization 
Program were $325.0 million and $314.7 million, respectively. Commitment fees at a rate of 35 basis points are charged on 
amounts made available but not borrowed under the Accounts Receivable Securitization Program.

CASH POOLING

Certain of our subsidiaries participate in cash pooling arrangements (the "Cash Pools") to help manage global liquidity 
requirements. We utilize the following Cash Pools: (i) two Cash Pools with Bank Mendes Gans, an independently operated wholly 
owned subsidiary of ING Group, one of which we use to manage global liquidity requirements for our QRSs and the other for our 
TRSs; (ii) two Cash Pools with JP Morgan Chase Bank, N.A. ("JPM"), one of which we use to manage liquidity requirements for our 
QRSs in the Asia Pacific region and the other for our TRSs in the Asia Pacific region; and (iii) two Cash Pools with JPM, which we 
entered into in the third quarter of 2022, one of which we use to manage liquidity requirements for our QRSs in the Europe, Middle 
East, and Africa regions and the other for our TRSs in the Europe, Middle East, and Africa regions. 

Under each of the Cash Pools, cash deposited by participating subsidiaries with certain financial institutions is pledged as security 
against the debit balances of other participating subsidiaries with legal rights of offset provided to the financial institutions, and, 
therefore, such amounts are presented in our Consolidated Balance Sheets on a net basis. Each subsidiary receives interest on 
the cash balances held on deposit or pays interest on its debit balances based on an applicable rate as defined in the Cash Pools.

LETTERS OF CREDIT

As of December 31, 2022, we had outstanding letters of credit totaling $39.8 million, of which $3.8 million reduce our borrowing 
capacity under the Revolving Credit Facility (as described above). The letters of credit expire at various dates between January 
2023 and March 2025.

DEBT COVENANTS

The Credit Agreement, our bond indentures and other agreements governing our indebtedness contain certain restrictive financial 
and operating covenants, including covenants that restrict our ability to complete acquisitions, pay cash dividends, incur 
indebtedness, make investments, sell assets and take other specified corporate actions. The covenants do not contain a rating 
trigger. Therefore, a change in our debt rating would not trigger a default under the Credit Agreement, our bond indentures or other 
agreements governing our indebtedness. The Credit Agreement requires that we satisfy a net total lease adjusted leverage ratio 
and a fixed charge coverage ratio on a quarterly basis and our bond indentures require that, among other things, we satisfy a 
leverage ratio (not lease adjusted) or a fixed charge coverage ratio (not lease adjusted), as a condition to taking actions such as 
paying dividends and incurring indebtedness.

54

IRON MOUNTAIN 2022 FORM 10-K

Table of Contents

Part II

The Credit Agreement uses EBITDAR-based calculations and the bond indentures use earnings before interest, taxes, depreciation 
and amortization ("EBITDA") based calculations as the primary measures of financial performance for purposes of calculating 
leverage and fixed charge coverage ratios. The EBITDAR- and EBITDA-based leverage calculations include our consolidated 
subsidiaries, other than those we have designated as "Unrestricted Subsidiaries" as defined in the Credit Agreement and bond 
indentures. Generally, the Credit Agreement and the bond indentures use a trailing four fiscal quarter basis for purposes of the 
relevant calculations and require certain adjustments and exclusions for purposes of those calculations, which make the calculation 
of financial performance for purposes of those calculations under the Credit Agreement and bond indentures not directly 
comparable to Adjusted EBITDA as presented herein. These adjustments can be significant. For example, the calculation of 
financial performance under the Credit Agreement and certain of our bond indentures includes (subject to specified exceptions and 
caps) adjustments for non-cash charges and for expected benefits associated with (i) completed acquisitions, (ii) certain executed 
lease agreements associated with our data center business that have yet to commence and (iii) restructuring and other strategic 
initiatives. The calculation of financial performance under our other bond indentures includes, for example, adjustments for non-
cash charges and for expected benefits associated with (i) completed acquisitions, and (ii) events that are extraordinary, unusual or 
non-recurring.

Our leverage and fixed charge coverage ratios under the Credit Agreement as of December 31, 2022 are as follows:

Net total lease adjusted leverage ratio

Fixed charge coverage ratio

DECEMBER 31, 2022 MAXIMUM/MINIMUM ALLOWABLE

5.1 

2.4 

Maximum allowable of 7.0

Minimum allowable of 1.5

We are in compliance with our leverage and fixed charge coverage ratios under the Credit Agreement, our bond indentures and 
other agreements governing our indebtedness as of December 31, 2022. Noncompliance with these leverage and fixed charge 
coverage ratios would have a material adverse effect on our financial condition and liquidity.

___________________________________________________________________________________________________

Our ability to pay interest on or to refinance our indebtedness depends on our future performance, working capital levels and 
capital structure, which are subject to general economic, financial, competitive, legislative, regulatory and other factors which may 
be beyond our control. There can be no assurance that we will generate sufficient cash flow from our operations or that future 
financings will be available on acceptable terms or in amounts sufficient to enable us to service or refinance our indebtedness or to 
make necessary capital expenditures.

DERIVATIVE INSTRUMENTS

INTEREST RATE SWAP AGREEMENTS

In November 2022, we entered into a forward-starting interest rate swap agreement to limit our exposure to changes in interest 
rates on future borrowings under our Virginia Credit Agreement. The forward-starting interest rate swap agreement commences in 
July 2023 and expires in October 2025 (the "October 2025 Interest Rate Swap Agreement"). The October 2025 Interest Rate Swap 
Agreement has an initial notional value of $4.8 million, which is contracted to increase in monthly increments beginning in August 
2023 to June 2025 to a total notional value of $153.8 million. Under the October 2025 Interest Rate Swap Agreement, we will 
receive variable rate interest payments based upon SOFR, in exchange for the payment of a fixed interest rate as specified in the 
October 2025 Interest Rate Swap Agreement.

In March 2018, we entered into interest rate swap agreements to limit our exposure to changes in interest rates on a portion of our 
floating rate indebtedness. These swap agreements expired in March 2022. In July 2019, we entered into forward-starting interest 
rate swap agreements to limit our exposure to changes in interest rates on a portion of our floating rate indebtedness. These 
forward-starting interest rate swap agreements commenced in March 2022. As of December 31, 2022, we have $350.0 million in 
notional value outstanding on the interest rate swap agreements, which expire in March 2024 (the "March 2024 Interest Rate Swap 
Agreements"). Under the March 2024 Interest Rate Swap Agreements, we receive variable rate interest payments associated with 
the notional amount of each interest rate swap, based upon one-month LIBOR, in exchange for the payment of fixed interest rates 
as specified in the March 2024 Interest Rate Swap Agreements.

We have designated each of the interest rate swap agreements described above as cash flow hedges.

CROSS-CURRENCY SWAP AGREEMENTS

We enter into cross-currency swap agreements to hedge the variability of exchange rate impacts between the United States dollar 
and the Euro. The cross-currency swap agreements are designated as a hedge of net investment against certain of our Euro 
denominated subsidiaries and require an exchange of the notional amounts at maturity.

Table of Contents

Part II

In August 2019, we entered into cross-currency swap agreements whereby we notionally exchanged $110.0 million at an interest 
rate of 6.0% for approximately 99.1 million Euros at a weighted average interest rate of approximately 3.65%. These cross-
currency swap agreements expire in August 2023. In October 2022, one of these cross-currency swap agreements was amended 
to increase the notional value exchanged from approximately 49.5 million Euros at an interest rate of 3.6% to approximately 55.5 
million Euros at an interest rate of (9.5%), resulting in a total notional value exchanged of approximately 105.0 million Euros at a 
weighted average interest rate of approximately (3.3%).

In September 2020, we entered into cross-currency swap agreements whereby we notionally exchanged approximately $359.2 
million at an interest rate of 4.5% for 300.0 million Euros at a weighted average interest rate of approximately 3.4%. These cross-
currency swap agreements expire in February 2026. In May 2022, these cross-currency swaps were amended to increase the 
notional value exchanged to approximately 340.5 million Euros at a weighted average interest rate of approximately 1.2%. In 
October 2022, these cross-currency swaps were further amended to increase the notional value exchanged to approximately 362.1 
million Euros at a weighted average interest rate of approximately 0.2%.

See Note 6 to Notes to Consolidated Financial Statements included in this Annual Report for additional information on our 
derivative instruments. 

ACQUISITIONS  

See Note 3 to Notes to Consolidated Financial Statements included in this Annual Report for information regarding our 2022 
acquisitions.

ITRENEW

On January 25, 2022, in order to expand our ALM operations, we acquired an approximately 80% interest in ITRenew, at an agreed 
upon purchase price of $725.0 million, subject to certain working capital adjustments at, and subsequent to, the closing (the 
"ITRenew Transaction"). At closing, we paid approximately $748.8 million and acquired approximately $30.7 million of cash on 
hand, for a net purchase price of approximately $718.1 million for the ITRenew Transaction. The acquisition agreement provides us 
the option to purchase, and provides the shareholders of ITRenew the option to sell, the remaining approximately 20% interest in 
ITRenew as follows: (i) approximately 16% on or after the second anniversary of the ITRenew Transaction and (ii) approximately 
4% on or after the third anniversary of the ITRenew Transaction (collectively, the "Remaining Interests"). The total payments for the 
Remaining Interests, based on the achievement of certain targeted performance metrics, will be no less than $200.0 million and no 
more than $531.0 million (the "Deferred Purchase Obligation"). From January 25, 2022, we consolidate 100% of the revenues and 
expenses associated with this business. The Deferred Purchase Obligation is reflected as a long-term liability in our Consolidated 
Balance Sheet at December 31, 2022, and, accordingly, we have not reflected any non-controlling interests associated with the 
ITRenew Transaction as the Remaining Interests have non-substantive equity interest rights. Subsequent increases or decreases 
in the fair value estimate of the Deferred Purchase Obligation are included as a component of Other (income) expense, net in our 
Consolidated Statements of Operations until the Deferred Purchase Obligation is settled or paid.

XDATA PROPERTIES

On October 5, 2022, in order to further expand our data center operations in Europe, we completed the acquisition of XData 
Properties S.L.U., a data center colocation space and solutions provider with a data center in Spain, which we accounted for as an 
asset acquisition, for (i) cash consideration of 78.9 million Euros (or approximately $78.2 million, based upon the exchange rate 
between the Euro and the United States dollar on the closing date of this acquisition), subject to adjustments, and (ii) up to 10.0 
million Euros (or approximately $9.9 million, based upon the exchange rate between the Euro and the United States dollar on the 
closing date of this acquisition) of additional consideration, payable based on the achievement of certain power connection 
milestones through December 2024.

OTHER 2022 ACQUISITIONS

In addition to the transactions noted above, during the year ended December 31, 2022, in order to enhance our existing operations 
in Morocco and expand our fine arts operations in China - Hong Kong S.A.R. and North America, we completed the acquisition of a 
records management company, a fine arts company and the assets of a second fine arts company, for a total combined purchase 
price of approximately $11.6 million, including deferred purchase obligations, purchase price holdbacks and other deferred 
payments of approximately $4.6 million.

INVESTMENTS

Part II

See Note 5 to Notes to Consolidated Financial Statements included in this Annual Report for information regarding our joint 
ventures.

CLUTTER JOINT VENTURE

In February 2022, the joint venture formed by MakeSpace Labs, Inc. and us (the "MakeSpace JV") entered into an agreement with 
Clutter, Inc. ("Clutter") pursuant to which the equityholders of the MakeSpace JV contributed their ownership interests in the 
MakeSpace JV and Clutter’s shareholders contributed their ownership interests in Clutter to create a newly formed venture (the 
"Clutter JV"). In exchange for our 49.99% interest in the MakeSpace JV, we received an approximate 27% interest in the Clutter JV 
(the "Clutter Transaction"). As a result of the Clutter Transaction, we recognized a gain related to our contributed interest in the 
MakeSpace JV of approximately $35.8 million, which was recorded to Other, net, a component of Other expense (income), net 
during the year ended December 31, 2022.

WEB WERKS JOINT VENTURE

In April 2021, we closed on an agreement to form a joint venture (the "Web Werks JV") with the shareholders of Web Werks India 
Private Limited, a colocation data center provider in India. In connection with the formation of the Web Werks JV, we made an initial 
investment of approximately 3,750.0 million Indian rupees (or approximately $50.1 million, based upon the exchange rate between 
the United States dollar and Indian rupee on the closing date of the initial investment) in exchange for a noncontrolling interest in 
the form of convertible preference shares in the Web Werks JV. In August 2022, we made an additional investment of 
approximately 3,750.0 million Indian rupees (or approximately $46.1 million, based upon the exchange rate between the United 
States dollar and Indian rupee on the date of the additional investment) in exchange for an additional interest in the form of 
convertible preference shares in the Web Werks JV (the "Second Web Werks JV Investment"). Under the terms of the Web Werks 
JV shareholder agreement, we are required to make an additional investment of approximately 3,750.0 million Indian rupees by 
May 2023. Subsequent to the Second Web Werks JV Investment, the shareholders of Web Werks retained control of the financial 
and operating decisions of the Web Werks JV through their control of Web Werks JV's board of directors. As we do not control the 
board of directors or the key management decisions of the Web Werks JV, we account for our interest in the Web Werks JV as an 
equity method investment.

JOINT VENTURE SUMMARY

The following joint ventures are accounted for as equity method investments and are presented as a component of Other within

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. The only significant concentrations of liquid investments as of 
December 31, 2022 related to cash and cash equivalents held in money market funds. 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, 2022, our cash and 
cash equivalents balance was $141.8 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, 2022, we had $2,341.4 million of variable rate debt outstanding with a weighted average variable interest rate 
of approximately 5.8%, and $8,308.9 million of fixed rate debt outstanding. As of December 31, 2022, approximately 78% of our 
total debt outstanding was fixed. 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, 2022 would have been reduced by approximately $17.3 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, 2022.

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, Brazilian real and the 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 the Euro. These cross-currency swap agreements are designated as a hedge of net investment against certain of 
our Euro 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.

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 2022 functional currencies, relative to the United 
States dollar, would result in a reduction in our equity of approximately $377.4 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, 2022 (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, 2022.

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, 2022, 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, 2022, 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, 2022, of the Company and our report 
dated February 23, 2023, 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, 2022 and 2021, the related consolidated statements of operations, comprehensive income (loss), equity, and 
cash flows, for each of the three years in the period ended December 31, 2022, 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, 2022 and 2021, and the results of its operations and 
its cash flows for each of the three years in the period ended December 31, 2022, 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, 2022, 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 23, 2023, 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 MATTERS

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that 
were communicated or required to be communicated to the audit committee and that (1) relate 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 matters below, providing a separate opinion on the critical audit matters or on the 
accounts or disclosures to which they relate.

Part IV

GOODWILL - GLOBAL DATA CENTER AND ASSET LIFECYCLE MANAGEMENT 
REPORTING UNITS - 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 each reporting unit to its carrying 
value. The Company determined the fair value of the Global Data Center reporting unit using a combined approach based on the 
present value of future cash flows (the "Discounted Cash Flow Model") and market multiples (the "Market Approach"). The 
Company determined the fair value of the Asset Lifecycle Management reporting unit using 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, discount rates and capital expenditures. The determination of the fair 
value using the Market Approach requires management to make significant assumptions related to adjusted earnings before 
interest, taxes, depreciation and amortization ("Adjusted EBITDA") multiples. Changes in economic and operating conditions 
impacting these assumptions or changes in multiples could result in goodwill impairments in future periods. The goodwill balances 
allocated to the Global Data Center and Asset Lifecycle Management reporting units were $408 million and $617 million, 
respectively, as of October 1, 2022 (goodwill impairment testing date). The fair value of both the Global Data Center and Asset 
Lifecycle Management reporting units exceeded its respective carrying value as of the measurement date and, therefore, no 
impairment was recognized.

The fair value exceeded the carrying value of the Global Data Center and Asset Lifecycle Management reporting units by less than 
30%, accordingly, auditing the assumptions used in the goodwill impairment analysis for this reporting unit involved especially 
subjective judgment.

HOW THE CRITICAL AUDIT MATTER WAS ADDRESSED IN THE AUDIT

Our audit procedures related to future revenue growth rates, operating margins and capital expenditures (collectively, the 
"Projected Cash Flows"), the selection of discount rates, and Adjusted EBITDA multiples for these reporting units included the 
following, among others: 

• We evaluated management’s ability to accurately forecast by comparing actual results to management’s historical forecasts. 

• We evaluated the reasonableness of management’s Projected Cash Flows by comparing it to (1) historical results, (2) internal 

communications to management and the Board of Directors, and (3) forecasted information included in Company press releases 
and industry reports of the Company and companies in its peer group.

• With the assistance of our fair value specialists, we evaluated the discount rates, including testing the underlying source 

information and the mathematical accuracy of the calculations, and developing a range of independent estimates and comparing 
those to the discount rates selected by management.

• With the assistance of our fair value specialists, we evaluated the Adjusted EBITDA multiples, including testing the underlying 
source information and mathematical accuracy of the calculations and comparing the multiples selected by management to its 
guideline companies for the Global Data Center reporting unit.

• We tested the effectiveness of controls over the evaluation of goodwill for impairment, including those over the Projected Cash 
Flows and discount rates and, additionally, for the Global Data Center reporting unit, the selection of the Adjusted EBITDA 
multiples. 

ACQUISITIONS - ITRENEW BUSINESS - SUPPLIER RELATIONSHIP INTANGIBLE ASSET-
REFER TO NOTE 3 TO THE FINANCIAL STATEMENTS

CRITICAL AUDIT MATTER DESCRIPTION

The Company completed the acquisition of 80% of the ITRenew business for $725 million on January 25, 2022. The acquisition 
included a deferred purchase obligation for the Company to acquire the remaining ownership percentage based on achievement of 
certain performance targets. The Company determined that the fair value of the deferred purchase obligation was $275 million. The 
Company accounted for the acquisition under the acquisition method of accounting for business combinations. Accordingly, the 
purchase price was allocated to the assets acquired and liabilities assumed based on their respective fair values, including a 
supplier relationship intangible asset of $472 million. Management estimated the fair value of the supplier relationship intangible 
asset using the multi-period excess earnings method, which is a specific discounted cash flow method. The fair value determination 
of the supplier relationship intangible asset required management to make significant estimates and assumptions related to future 
cash flows and the selection of the discount rate.

68

IRON MOUNTAIN 2022 FORM 10-K

Table of Contents

Part IV

We identified the supplier relationship intangible asset for ITRenew business as a critical audit matter because of the significant 
estimates and assumptions management made to determine the fair value of the asset. This required a high degree of auditor 
judgment and an increased extent of effort, including the need to involve our fair value specialists, when performing audit 
procedures to evaluate the reasonableness of management’s forecasts of future cash flows and the selection of the discount rate 
for the supplier relationship intangible asset.

HOW THE CRITICAL AUDIT MATTER WAS ADDRESSED IN THE AUDIT

Our audit procedures related to the forecasts of future cash flows and the selection of the discount rate for the supplier relationship 
intangible asset included the following, among others:

• We assessed the reasonableness of management’s forecasts of future cash flows by comparing the projections to historical 

results and certain external market information. 

• With the assistance of our fair value specialists, we evaluated the reasonableness of the (1) valuation methodology and (2) 

discount rate by:

◦ Testing the source information underlying the determination of the discount rate and testing the mathematical accuracy 

of the calculation.

◦ Developing a range of independent estimates and comparing those to the discount rate selected by management.

• We evaluated whether the estimated future cash flows were consistent with evidence obtained in other areas of the audit.

• We tested the effectiveness of controls over the valuation of the supplier relationship intangible asset, including management’s 

controls over forecasts of future cash flows and selection of the discount rate.

Part IV

IRON MOUNTAIN INCORPORATED
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2022
(In thousands, except share and per share data) 

1. NATURE OF BUSINESS

The accompanying financial statements represent the consolidated accounts of Iron Mountain Incorporated, a Delaware 
corporation ("IMI"), and its subsidiaries ("we" or "us"). 

We help organizations around the world protect their information, reduce storage costs, comply with regulations, facilitate corporate 
disaster recovery, and better use their information and information technology ("IT") infrastructure for business advantages, 
regardless of its format, location or life cycle stage. We do this by storing physical records and data backup media, offering 
information management solutions, and providing data center space for enterprise-class colocation and hyperscale deployments. 
We offer comprehensive records and information management services and data management services, along with the expertise 
and experience to address complex storage and information management challenges such as rising storage rental costs, legal and 
regulatory compliance, and disaster recovery requirements. We provide secure and reliable data center facilities to protect digital 
information and ensure the continued operation of our customers’ IT infrastructure, with reliable and flexible deployment options. 
Our asset lifecycle management ("ALM") business allows us to provide end-to-end asset lifecycle services for hyperscale, 
corporate data center and corporate end-user device assets.

In September 2022, we announced a global program designed to accelerate the growth of our business ("Project Matterhorn"). 
Project Matterhorn will focus 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 will be investing to accelerate growth and to capture a 
greater share of the large, global addressable markets in which we operate. See Note 13.

We have been organized and have operated as a real estate investment trust for United States federal income tax purposes 
("REIT") beginning with our taxable year ended December 31, 2014.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A. PRINCIPLES OF CONSOLIDATION

The accompanying financial statements reflect our financial position, results of operations, comprehensive income (loss), equity 
and cash flows on a consolidated basis. The accompanying financial statements include the results of those entities over which we 
have a controlling financial interest and we are deemed to be the primary beneficiary. All intercompany transactions and account 
balances have been eliminated.

B. USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 
("GAAP") requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, 
revenues and expenses, and related disclosure of contingent assets and liabilities at the date of the financial statements and for 
the period then ended. On an ongoing basis, we evaluate the estimates used. We base our estimates on historical experience, 
actuarial estimates, current conditions and various other assumptions that we believe to be reasonable under the circumstances. 
These estimates form the basis for making judgments about the carrying values of assets and liabilities and are not readily 
apparent from other sources. Actual results may differ from these estimates.

C. FOREIGN CURRENCY

Local currencies are the functional currencies for our operations outside the United States, with the exception of certain foreign 
holding companies, whose functional currency is the United States dollar. In those instances where the local currency is the 
functional currency, assets and liabilities are translated at period-end exchange rates, and revenues and expenses are translated 
at average exchange rates for the applicable period. See Note 2.r.

(In thousands, except share and per share data)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

D. CASH AND CASH EQUIVALENTS

Cash and cash equivalents include cash on hand and cash invested in highly liquid short-term securities, which have remaining 
maturities at the date of purchase of less than 90 days. Cash and cash equivalents are carried at cost, which approximates fair 
value. 

E. ALLOWANCE FOR DOUBTFUL ACCOUNTS AND CREDIT MEMO RESERVES

We maintain an allowance for doubtful accounts and a credit memo reserve for estimated losses resulting from the potential 
inability of our customers to make required payments and potential disputes regarding billing and service issues. We calculate and 
monitor our allowance considering future potential economic and macroeconomic conditions and reasonable and supportable 
forecasts for expected future collectability of our outstanding receivables, in addition to considering our past loss experience, 
current and prior trends in our aged receivables and credit memo activity. Our considerations when calculating our allowance 
include, but are not limited to, the following: the location of our businesses, the composition of our customer base, our product and 
service lines, potential future economic unrest, and potential future macroeconomic factors, including natural disasters. Continued 
adjustments will be made should there be any material change to reasonable and supportable forecasts that may impact our 
likelihood of collection, as it becomes evident. Our highly diverse global customer base, with no single customer accounting for 
more than approximately 1% of revenue during the years ended December 31, 2022, 2021 and 2020, limits our exposure to 
concentration of credit risk. Additionally, we write off uncollectible balances as circumstances warrant, generally no later than one 
year past due.

The rollforward of the allowance for doubtful accounts and credit memo reserves is as follows:

(1) Primarily consists of the issuance of credit memos, the write-off of accounts receivable and the impact associated with currency translation adjustments.

F. INVENTORY

Inventory is stated at the lower of cost or net realizable value, based on a first-in, first-out methodology. Our inventory primarily 
consists of IT-related assets including memory, central processing units, hard drives, adaptors and networking. All of our inventory 
is considered finished goods. Inventory is included as a component of Prepaid expenses and other in our Consolidated Balance 
Sheets. At December 31, 2022, we have inventory of approximately $11,726, net of related reserves for obsolete, excess and slow-
moving inventory, related to our ALM business. We had no inventory as of December 31, 2021.

G. CONCENTRATIONS OF 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. The only significant concentrations of liquid investments as of 
December 31, 2022 and 2021 related to cash and cash equivalents held in money market funds. 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 $75,000. See Note 2.p.

CAPITALIZED INTEREST

We capitalize interest expense during the active construction period of major capital projects. Capitalized interest is added to the 
cost of the underlying assets and is amortized over the useful lives of the assets. During the years ended December 31, 2022, 
2021 and 2020, capitalized interest is as follows:

14,078  $ 

12,673  $ 

14,321 

INTERNAL USE SOFTWARE

We develop various software applications for internal use. Computer software costs associated with internal use software are 
expensed as incurred until certain capitalization criteria are met. Third party consulting costs, as well as payroll and related costs 
for employees directly associated with, and devoting time to, the development of internal use computer software projects (to the 
extent time is spent directly on the project) are capitalized. Capitalization begins when the design stage of the application has been 
completed and it is probable that the project will be completed and used to perform the function intended. Capitalization ends when 
the asset is ready for its intended use. Depreciation begins when the software is placed in service. Computer software costs that 
are capitalized are periodically evaluated for impairment.

During the years ended December 31, 2022, 2021 and 2020, capitalized costs associated with the development of internal use 
computer software projects are as follows:

ASSET RETIREMENT OBLIGATIONS

Entities are required to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. Asset 
retirement obligations represent the costs to replace or remove tangible long-lived assets required by law, regulatory rule or 
contractual agreement. Our asset retirement obligations are primarily the result of requirements under our facility lease agreements 
which generally have "return to original condition" clauses which would require us to remove or restore items such as shred pits, 
vaults, demising walls and office build-outs, among others. The significant assumptions used in estimating our aggregate asset 
retirement obligations are the timing of removals, the probability of a requirement to perform, estimated cost and associated 
expected inflation rates that are consistent with historical rates and credit-adjusted risk-free rates that approximate our incremental 
borrowing rate. Our asset retirement obligations at December 31, 2022 and 2021 were $36,119 and $36,493, respectively, and are 
included in Other Long-term Liabilities in our Consolidated Balance Sheets.

J. LEASES

We lease facilities for certain warehouses, data centers and office space. We also have land leases, including those on which 
certain facilities are located. The majority of our leased facilities are classified as operating leases that, on average, have initial 
lease terms of five to 10 years, with one or more lease renewal options to extend the lease term. Our lease renewal option terms 
generally range from one to five years. The exercise of the lease renewal option is at our sole discretion and may contain fixed 
rent, fair market value based rent or Consumer Price Index rent escalation clauses. We include option periods in the lease term 
when our failure to renew the lease would result in an economic disincentive, thereby making it reasonably certain that we will 
renew the lease. We recognize straight line rental expense over the life of the lease and any fair market value or Consumer Price 
Index rent escalations are recognized as variable lease expense in the period in which the obligation is incurred. In addition, we 
lease certain vehicles and equipment. Vehicle and equipment leases typically have lease terms ranging from one to seven years.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

We account for all leases, both operating and financing, in accordance with Accounting Standards Codification ("ASC") Topic 842 
Leases, ("ASC 842"). Our accounting policy provides that leases with an initial term of 12 months or less will not be included within 
the lease right-of-use assets and lease liabilities recognized on our Consolidated Balance Sheets. We recognize the lease 
payments for those leases with an initial term of 12 months or less in our Consolidated Statements of Operations on a straight-line 
basis over the lease term.

The lease right-of-use assets and related lease liabilities are classified as either operating or financing. Lease right-of-use assets 
are calculated as the net present value of future payments plus any capitalized initial direct costs less any tenant improvements or 
lease incentives. Lease liabilities are calculated as the net present value of future payments. In calculating the present value of the 
lease payments, we utilize the rate stated in the lease (in the limited circumstances when such rate is explicitly stated) or, if no rate 
is explicitly stated, we utilize a rate that reflects our securitized incremental borrowing rate by geography for the lease term. We 
account for nonlease components (which include common area maintenance, taxes, and insurance) with the related lease 
component. Any variable nonlease components are not included within the lease right-of-use asset and lease liability on our 
Consolidated Balance Sheets, and instead, are reflected as an expense in the period incurred.

Operating and financing lease right-of-use assets and lease liabilities as of December 31, 2022 and 2021 are as follows:

K. LONG-LIVED ASSETS

We review long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of such 
assets may not be recoverable. Recoverability of these assets is determined by comparing the sum of the forecasted undiscounted 
net cash flows of the operation to which the assets relate to their carrying amount. The operations are generally distinguished by 
the business segment and geographic region in which they operate. If it is determined that we are unable to recover the carrying 
amount of the assets, the long-lived assets are written down, on a pro rata basis, to fair value. Fair value is determined based on 
discounted cash flows or appraised values, depending upon the nature of the assets. Long-lived assets, including finite-lived 
intangible assets, are amortized over their useful lives. Annually, or more frequently if events or circumstances warrant, we assess 
whether a change in the lives over which long-lived assets, including finite-lived intangible assets, are amortized is necessary.

through sale and sale-leaseback transactions. The terms for these leases are consistent with the terms of our lease portfolio, which are disclosed in Note 2.j.

L. GOODWILL AND OTHER INDEFINITE-LIVED INTANGIBLE ASSETS

Goodwill and intangible assets with indefinite lives are not amortized but are reviewed annually for impairment, or more frequently if 
impairment indicators arise. Other than goodwill, we currently have no intangible assets that have indefinite lives and which are not 
amortized.

We test goodwill annually on October 1, and more frequently if impairment indicators arise that would require an interim test. The 
following is a discussion regarding (i) interim goodwill impairment review for our Fine Arts reporting unit during the first quarter of 
2020, (ii) the reporting units at which level we tested goodwill for impairment as of October 1, 2021 and the composition of these 
reporting units at December 31, 2021 (including the amount of goodwill associated with each reporting unit), (iii) interim reporting 
unit changes and goodwill impairment review during the second quarter of 2022 and (iv) the reporting units at which level we tested 
goodwill for impairment as of October 1, 2022 and the composition of these reporting units at December 31, 2022 (including the 
amount of goodwill associated with each reporting unit).

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

I. INTERIM GOODWILL IMPAIRMENT REVIEW - FINE ARTS, FIRST QUARTER OF 2020

During the first quarter of 2020, we concluded that we had a triggering event related to our Fine Arts reporting unit, requiring us to 
perform an interim goodwill impairment test. The primary factor contributing to our conclusion was the expected impact of the 
COVID-19 pandemic to this particular business and its customers and revenue sources, which caused us to believe it was more 
likely than not that the carrying value of our Fine Arts reporting unit exceeded its fair value. During the first quarter of 2020, we 
performed an interim goodwill impairment test for our Fine Arts reporting unit utilizing a discounted cash flow model, with updated 
assumptions on future revenues, operating expenditures and capital expenditures. We concluded that the fair value of our Fine Arts 
reporting unit was less than its carrying value, and, therefore, we recorded a $23,000 impairment charge on the goodwill 
associated with this reporting unit during the first quarter of 2020. Factors that may impact these assumptions include, but are not 
limited to: (i) our ability to maintain, or grow, storage and retail service revenues in this reporting unit in line with current 
expectations and (ii) our ability to manage our fixed and variable costs in this reporting unit in line with potential future revenue 
declines.

II. REPORTING UNITS AS OF OCTOBER 1, 2021

Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2021 were as follows: 

• North America Records and Information Management ("North 

• Asia Records and Information Management ("Asia RIM")

• Europe Records and Information Management ("Europe RIM")

• Latin America Records and Information Management ("Latin 

America RIM")

• Australia and New Zealand Records and Information 

Management ("ANZ RIM")

• Global Data Center

• Fine Arts

• Entertainment Services

We concluded that the goodwill associated with each of our reporting units was not impaired as of such date. There were no 
changes to the composition of our reporting units between October 1, 2021 and December 31, 2021.

III. 2022 REPORTING UNIT CHANGES

During the second quarter of 2022, as a result of the realignment of our global managerial structure, we reassessed the 
composition of our reportable segments (see Note 11 for a description and definition of our reportable segments) as well as our 
reporting units. 

We note the following changes to our reporting units as a result of the reassessment described above:

• our former Europe RIM reporting unit is now managed as two separate reporting units: (i) our Middle East, North Africa and 
Turkey ("MENAT") businesses will comprise our "MENAT RIM" reporting unit and (ii) our other businesses in Europe and 
South Africa ("ESA") will comprise our "ESA RIM" reporting unit;

• our former ANZ RIM and Asia RIM reporting units are now managed as one "APAC RIM" reporting unit; and

• our ALM business, which includes our legacy secure IT asset disposition business (which was previously primarily included in 

our North America RIM reporting unit) and the business acquired through our acquisition of Intercept Parent, Inc. 
("ITRenew"), will comprise our newly formed "ALM" reporting unit. 

There were no changes to our Latin America RIM, Global Data Center and Fine Arts reporting units. We have reassigned goodwill 
associated with the reporting units impacted by the reorganization on a relative fair value basis, where appropriate. The fair value 
of each of our new reporting units was determined based on the application of a combined weighted average approach of 
preliminary fair value multiples of revenue and earnings and discounted cash flow techniques. These fair values represent our best 
estimate and preliminary assessment of goodwill allocations to each of the new reporting units on a relative fair value basis. We 
have completed an interim goodwill impairment analysis before and after the reporting unit changes, and we have concluded that 
the goodwill associated with each of our reporting units was not impaired.

IV. REPORTING UNITS AS OF OCTOBER 1, 2022

Our reporting units at which level we performed our goodwill impairment analysis as of October 1, 2022 were as follows: 

• North America RIM

• ESA RIM

• MENAT RIM

• Latin America RIM

• APAC RIM

• Entertainment Services

• Global Data Center

• Fine Arts

• ALM

We concluded that the goodwill associated with each of our reporting units was not impaired as of such date. There were no 
changes to the composition of our reporting units between October 1, 2022 and December 31, 2022.

The fair value of our reporting units has generally been determined using a combined approach based on the present value of 
future cash flows (the "Discounted Cash Flow Model") and market multiples (the "Market Approach"). 

The Discounted Cash Flow Model incorporates significant 
assumptions including future revenue growth rates, 
operating margins, discount rates and capital expenditures. 

The Market Approach requires us to make assumptions 
related to Adjusted EBITDA (as defined in Note 11) 
multiples. 

Changes in economic and operating conditions impacting these assumptions or changes in multiples could result in goodwill 
impairments in future periods. In conjunction with our annual goodwill impairment reviews, we reconcile the sum of the valuations 
of all of our reporting units to our market capitalization as of such dates.

M. FINITE-LIVED INTANGIBLE ASSETS AND LIABILITIES

I. CUSTOMER AND SUPPLIER RELATIONSHIP INTANGIBLE ASSETS

Customer and supplier relationship intangible assets, which are acquired through either business combinations or acquisitions of 
customer relationships, are amortized over periods ranging from 10 to 30 years. Customer and supplier relationship intangible 
assets are recorded based upon estimates of their fair value.

II. CUSTOMER INDUCEMENTS

Payments that are made to a customer in order to terminate the customer’s storage of records with its current records management 
vendor ("Permanent Withdrawal Fees"), or direct payments to a customer for which no distinct benefit is received in return, are 
collectively referred to as "Customer Inducements". Customer Inducements are treated as a reduction of the transaction price over 
periods ranging from one to 10 years and are included in storage and service revenue in the accompanying Consolidated 
Statements of Operations. If the customer terminates its relationship with us, the unamortized carrying value of the Customer 
Inducement intangible asset is charged to revenue. However, in the event of such termination, we generally collect, and record as 
income, Permanent Withdrawal Fees that generally equal or exceed the amount of the unamortized Customer Inducement 
intangible asset.

III. DATA CENTER INTANGIBLE ASSETS AND LIABILITIES

Finite-lived intangible assets associated with our Global Data Center Business consist of the following:

DATA CENTER IN-PLACE LEASE INTANGIBLE ASSETS AND DATA CENTER TENANT RELATIONSHIP INTANGIBLE 
ASSETS

Data Center In-Place Lease Intangible Assets ("Data Center In-Place Leases") and Data Center Tenant Relationship Intangible 
Assets ("Data Center Tenant Relationships") reflect the value associated with acquiring a data center operation with active tenants 
as of the date of acquisition. The value of Data Center In-Place Leases is determined based upon an estimate of the economic 
costs (such as lost revenues, tenant improvement costs, commissions, legal expenses and other costs to acquire new data center 
leases) avoided by acquiring a data center operation with active tenants that would have otherwise been incurred if the data center 
operation was purchased vacant. Data Center In-Place Leases are amortized over the weighted average remaining term of the 
acquired data center leases. The value of Data Center Tenant Relationships is determined based upon an estimate of the 
economic costs avoided upon lease renewal of the acquired tenants, based upon expectations of lease renewal. Data Center 
Tenant Relationships are amortized over the weighted average remaining anticipated life of the relationship with the acquired 
tenant.

DATA CENTER ABOVE-MARKET AND BELOW-MARKET IN-PLACE LEASE INTANGIBLE ASSETS

We record Data Center Above-Market In-Place Lease Intangible Assets ("Data Center Above-Market Leases") and Data Center 
Below-Market In-Place Lease Intangible Assets ("Data Center Below-Market Leases") at the net present value of the difference 
between (i) the contractual amounts to be paid pursuant to each in-place lease and (ii) management’s estimate of the fair market 
lease rates for each corresponding in-place lease. Data Center Above-Market Leases and Data Center Below-Market Leases are 
amortized over the remaining non-cancellable term of the acquired in-place lease to storage revenue.

The gross carrying amount and accumulated amortization of our finite-lived intangible assets as of December 31, 2022 and 2021, 
respectively, are as follows:

N. DEFERRED FINANCING COSTS

Deferred financing costs are amortized over the life of the related debt. If debt is retired early, the related unamortized deferred 
financing costs are written-off in the period the debt is retired to Other (income) expense, net. See Note 7.

O. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Every derivative instrument is required to be recorded in the balance sheet as either an asset or a liability measured at its fair 
value. Periodically, we acquire derivative instruments that are intended to hedge either cash flows or values that are subject to 
foreign exchange or other market price risk and not for trading purposes. We have formally documented our hedging relationships, 
including identification of the hedging instruments and the hedged items, as well as our risk management objectives and strategies 
for undertaking each hedge transaction. 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, thereby preserving our long-
term returns on invested capital. We may use interest rate swaps as a tool to maintain our targeted level of fixed rate debt. In 
addition, we may enter into cross-currency swaps to hedge the variability of exchange rates between the United States dollar and 
the currencies of our foreign subsidiaries, as well as interest rates. We may also use borrowings in foreign currencies, either 
obtained in the United States or by our foreign subsidiaries, to hedge foreign currency risk associated with our international 
investments. As of December 31, 2022 and 2021, none of our derivative instruments contained credit-risk related contingent 
features. See Note 6.

P. FAIR VALUE MEASUREMENTS

Entities are permitted under GAAP to elect to measure certain financial instruments and certain other items at either fair value or 
cost. We have elected the cost measurement option in all circumstances where we had an option. 

Our financial assets or liabilities that are carried at fair value are required to be measured using inputs from the three levels of the 
fair value hierarchy. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input 
that is significant to the fair value measurement. The three levels of the fair value hierarchy are as follows:

Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access at 
the measurement date.

Level 2—Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets 
or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest 
rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data by correlation or 
other means (market corroborated inputs).

Level 3—Unobservable inputs that reflect our assumptions about the assumptions that market participants would use in pricing the 
asset or liability. 

The assets and liabilities carried at fair value and measured on a recurring basis as of December 31, 2022 and 2021, respectively, 
are as follows:

(1) Money market funds and time deposits are measured based on quoted prices for similar assets and/or subsequent transactions.

(2) Certain trading securities are measured at fair value using quoted market prices.

(3) Certain trading securities are measured based on inputs other than quoted market prices that are observable.

(4) Derivative assets and liabilities include (i) interest rate swap agreements, including our forward-starting interest rate swap agreement, to limit our exposure to 

changes in interest rates on a portion of our floating rate indebtedness and on future borrowings from our Virginia Credit Agreement (as defined in Note 7) and (ii) 
cross-currency swap agreements to hedge the variability of exchange rate impacts between the United States dollar and the Euro and certain of our Euro 
denominated subsidiaries. Our derivative financial instruments are measured using industry standard valuation models using market-based observable inputs, 
including interest rate curves, forward and spot prices for currencies and implied volatilities. Credit risk is also factored into the determination of the fair value of our 
derivative financial instruments. See Note 6 for additional information on our derivative financial instruments.

(5) Primarily relates to the fair value of the Deferred Purchase Obligation associated with the ITRenew Transaction (each as defined in Note 3), which was determined 

utilizing a Monte-Carlo model and takes into account our forecasted projections as it relates to the underlying performance of the business. The Monte-Carlo 
simulation model incorporates assumptions as to expected gross profits over the applicable achievement period, including adjustments for the volatility of timing and 
amount of the associated revenue and costs, as well as discount rates that account for the risk of the underlying arrangement and overall market risks. Any material 
change to these assumptions may result in a significantly higher or lower fair value of the Deferred Purchase Obligation. During the fourth quarter of 2022, we 
recorded a change in the estimated fair value of the Deferred Purchase Obligation as described in Note 2.v.

There were no material items that were measured at fair value on a non-recurring basis for the years ended December 31, 2022 
and 2021, with the exception of: (i) the reporting units as presented in our goodwill impairment analysis (as disclosed in Note 2.l.); 
(ii) assets acquired and liabilities assumed through our acquisitions (as disclosed in Note 3); (iii) the redemption value of certain 
redeemable noncontrolling interests (as disclosed in Note 2.q.); (iv) our investments in the Frankfurt JV, the Clutter JV and the Web 
Werks JV (each as defined in Note 5); and (v) the fair value of our retained investment of our deconsolidated businesses (as 
described in Note 4), all of which are based on Level 3 inputs.

The fair value of our long-term debt, which was determined based on either Level 1 inputs or Level 3 inputs, is disclosed in Note 7. 
Long-term debt is measured at cost in our Consolidated Balance Sheets as of December 31, 2022 and 2021. 

Q. REDEEMABLE NONCONTROLLING INTERESTS

Certain unaffiliated third parties own noncontrolling interests in certain of our consolidated subsidiaries. The underlying agreements 
between us and our noncontrolling interest shareholders for these subsidiaries contain provisions under which the noncontrolling 
interest shareholders can require us to purchase their respective interests in such subsidiaries at certain times and at a purchase 
price as stipulated in the underlying agreements (generally at fair value). These put options make these noncontrolling interests 
redeemable and, therefore, these noncontrolling interests are classified as temporary equity outside of stockholders’ equity. 
Redeemable noncontrolling interests are reported at the higher of their redemption value or the noncontrolling interest holders’ 
proportionate share of the underlying subsidiaries net carrying value. Increases or decreases in the redemption value of the 
noncontrolling interest are offset against Additional Paid-in Capital.

In 2018, one of our noncontrolling interest shareholders exercised its option to put its ownership interest back to us. Upon the 
exercise of the put option, this noncontrolling interest became mandatorily redeemable by us, and, therefore, was accounted for as 
a liability rather than a component of redeemable noncontrolling interests. In May 2021, we agreed to final settlement terms and 
paid the put option price for the noncontrolling interest shares.

S. REVENUES

Our revenues consist of storage rental revenues as well as 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 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) destruction services, consisting primarily of (i) secure shredding of sensitive documents and the 
subsequent sale of shredded paper for recycling, the price of which can fluctuate from period to period, and (ii) the 
decommissioning, data erasure, processing and disposition or sale of IT hardware and component assets; (3) digital solutions, 
including the scanning, imaging and document conversion services of active and inactive records, and consulting services; and (4) 
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. 

We account for our revenue in accordance with ASC 606, Revenue from Contracts with Customers ("ASC 606"), with the exception 
of our data center revenue, as described below. Customers are generally billed monthly based on contractually agreed-upon terms, 
and storage rental and service revenues are recognized in the month the respective storage rental or service is provided, in line 
with the transfer of control to the customer. When storage rental fees or services are billed in advance, amounts related to future 
storage rental or prepaid service contracts are accounted for as deferred revenue and recognized upon the transfer of control to 
the customer, generally ratably over the contract term. Customer contracts generally include promises to provide monthly recurring 
storage and related services that are essentially the same over time and have the same pattern of transfer of control to the 
customer; therefore, most performance obligations represent a promise to deliver a series of distinct services over time (as 
determined for purposes of ASC 606, a "series"). For those contracts that qualify as a series, we apply the "right to invoice" 
practical expedient as we have a right to consideration from the customer in an amount that corresponds directly with the value of 
the underlying performance obligation transferred to the customer to date. Additionally, each purchasing decision is fully in the 
control of the customer; therefore, consideration beyond the current reporting period is variable and allocated to the specific period 
to which the consideration relates, which is consistent with the practical expedient. Revenue from product sales, the significant 
majority of which are shred paper and IT asset sales, is recognized at the point in time at which control transfers to the customer, 
which is generally upon shipment.

Our Global Data Center Business features storage rental provided to the customer at contractually specified rates over a fixed 
contractual period. Storage rental revenue related to the storage component of our Global Data Center Business is recognized on a 
straight-line basis over the contract term in accordance with ASC 842. The revenue related to the service component of our Global 
Data Center Business is recognized in the period the related services are provided.

The costs associated with the initial movement of customer records into physical storage and certain commissions are considered 
costs to obtain or fulfill customer contracts ("Contract Fulfillment Costs"). The following describes our significant Contract Fulfillment 
Costs:

INTAKE COSTS (AND ASSOCIATED DEFERRED REVENUE)

The costs of the initial intake of customer records into physical storage ("Intake Costs") are deferred and amortized as a 
component of depreciation and amortization in our Consolidated Statements of Operations generally over three years, consistent 
with the transfer of the performance obligation to the customer to which the asset relates. In instances where such Intake Costs are 
billed to the customer, the associated revenue is deferred and recognized over the same three-year period.

COMMISSIONS

Certain commission payments that are directly associated with the fulfillment of long-term contracts are capitalized and amortized 
as a component of depreciation and amortization in our Consolidated Statements of Operations generally over three years, 
consistent with the transfer of the performance obligation to the customer to which the asset relates. Certain direct commission 
payments associated with contracts with a duration of one year or less are expensed as incurred under the practical expedient 
which allows an entity to expense as incurred an incremental cost of obtaining a contract if the amortization period of the asset that 
the entity otherwise would have recognized is one year or less.

Contract Fulfillment Costs, which are included as a component of Other within Other Assets, Net, as of December 31, 2022 and

DATA CENTER LESSOR CONSIDERATIONS

Our Global Data Center Business features storage rental provided to customers at contractually specified rates over a fixed 
contractual period. Our data center revenue contracts are accounted for in accordance with ASC 842. ASC 842 provides a practical 
expedient which allows lessors to account for nonlease components (such as power and connectivity, in the case of our Global 
Data Center Business) with the related lease component if both the timing and pattern of transfer are the same for nonlease 
components and the lease component, and the lease component, if accounted for separately, would be classified as an operating 
lease. The single combined component is accounted for under ASC 842 if the lease component is the predominant component and 
is accounted for under ASC 606 if the nonlease components are the predominant components. We have elected to take this 
practical expedient. Our data center revenue contracts may contain Consumer Price Index rent escalation clauses. Consumer 
Price Index rent escalation clauses are recognized as income in the period earned.

Storage rental revenue, including revenue associated with power and connectivity, associated with our Global Data Center 
Business for the years ended December 31, 2022, 2021 and 2020 are as follows:

• Upon an employee’s retirement on or after attaining age 55 with at least five years of service, if the sum of (i) the award 

recipient’s age at retirement and (ii) the award recipient’s years of service with us totals at least 65, the award recipient is entitled 
to continued vesting of any outstanding Employee Stock-Based Awards, provided that their retirement occurs on or after a 
minimum of six months from the grant date (the "Retirement Criteria").

• Accordingly, (i) grants of Employee Stock-Based Awards to an employee who has met the Retirement Criteria on or before the 

date of grant, or will meet the Retirement Criteria before the six month anniversary in the year of the grant, will be expensed over 
six months from the date of grant and (ii) grants of Employee Stock-Based Awards to employees who will meet the Retirement 
Criteria during the award’s normal vesting period will be expensed between the date of grant and the date upon which the award 
recipient meets the Retirement Criteria.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

• Stock options and RSUs granted to award recipients who meet the Retirement Criteria will be delivered to the award recipient 
based upon the original vesting schedule. If an award recipient retires and has met the Retirement Criteria, stock options will 
remain exercisable until the original expiration date of the stock options. PUs granted to award recipients who meet the 
Retirement Criteria will be delivered in accordance with the original vesting schedule of the applicable PU award and remain 
subject to the same performance conditions.

Stock-based compensation expense for Employee Stock-Based Awards included in the accompanying Consolidated Statements of 
Operations for the years ended December 31, 2022, 2021 and 2020 is as follows:

The substantial majority of stock-based compensation expense for Employee Stock-Based Awards is included in Selling, general 
and administrative expenses in the accompanying Consolidated Statements of Operations.

STOCK OPTIONS

Options are generally granted with exercise prices equal to the market price of the stock on the date of grant; however, in certain 
instances, options are granted at prices greater than the market price of the stock on the date of grant. The substantial majority of 
options we issue become exercisable ratably over a period three years from the date of grant and have a contractual life of 10 
years from the date of grant, unless the holder’s employment is terminated sooner. Our non-employee directors are considered 
employees for purposes of our stock option plans and stock option reporting.

Our stock options outstanding at December 31, 2022 are based on the three-year vesting period (10 year contractual life) 
described above. 

Our equity compensation plans generally provide that, upon a vesting change in control (as defined in each plan), any unvested 
options and other awards granted thereunder shall vest immediately if an employee is terminated as a result of the change in 
control or terminates their own employment for good reason (as defined in each plan). On January 20, 2015, our stockholders 
approved the adoption of the Iron Mountain Incorporated 2014 Stock and Cash Incentive Plan, as amended (the "2014 Plan"). 

In May 2021, our stockholders approved an amendment to the 2014 Plan to (i) increase the number of shares of our common stock 
authorized for issuance thereunder by 8,000,000 from 12,750,000 to 20,750,000, (ii) extend the termination date of the 2014 Plan 
from May 24, 2027 to May 12, 2031, (iii) provide that, other than in specified circumstances, no equity-based award will vest before 
the first anniversary of the date of grant and (iv) provide that dividends and dividend equivalents are not paid with respect to stock 
options or stock appreciation rights.

A total of 20,750,000 shares of common stock have been reserved for grants of options and other rights under our various stock 
incentive plans, including the 2014 Plan. The number of shares available for grant under our various stock incentive plans at 
December 31, 2022 was 7,981,518.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

The weighted average fair value of stock options granted in 2022, 2021 and 2020 was $7.44, $3.23 and $2.35 per share, 
respectively. These values were estimated on the date of grant using the Black-Scholes option pricing model. The weighted 
average assumptions used for grants in the years ended December 31, 2022, 2021 and 2020 are as follows:

(1) Expected volatility is calculated utilizing daily historical volatility over a period that equates to the expected life of the option. 

(2) Risk-free interest rate is based on the United States Treasury interest rates whose term is consistent with the expected life (estimated period of time outstanding) of 

the stock options. 

(3) Expected dividend yield is considered in the option pricing model and represents our current annualized expected per share dividends over the current trade price of 

our common stock. 

(4) Expected life of the stock options granted is estimated using the historical exercise behavior of employees.

Our RSUs generally have a vesting period of three years from the date of grant. However, RSUs granted to our non-employee 
directors vest immediately upon grant. All RSUs accrue dividend equivalents associated with the underlying stock as we declare 
dividends. Dividends will generally be paid to holders of RSUs in cash upon the vesting date of the associated RSU and will be 
forfeited if the RSU does not vest. The fair value of RSUs is the excess of the market price of our common stock at the date of 
grant over the holder's purchase price (which is typically zero).

The fair value of RSUs vested during the years ended December 31, 2022, 2021 and 2020, are as follows:

The PUs we issue vest based on our performance against predefined operational and share based targets. The vesting is subject 
to a minimum level of return on invested capital in the third year of the performance period, and thereafter the number of PUs 
earned is based on (i) the revenue performance for each year averaged at the end of the three-year performance period, (ii) the 
total return on our common stock in relation to the MSCI United States REIT Index and (iii) for grants issued in 2021 and 2020, the 
revenue exit rate of new products in the last quarter of the three-year performance period. The number of PUs earned may range 
from 0% to approximately 238% of the initial award.

All of our PUs will be settled in shares of our common stock and are subject to cliff vesting three years from the date of the original 
PU grant. PUs are generally expensed over the three-year performance period. As detailed above, PUs granted are subject to the 
Retirement Criteria. PUs granted to recipients who meet the Retirement Criteria will continue to vest and be delivered in 
accordance with the original vesting schedule of the applicable PU award and remain subject to the same performance conditions. 

All PUs accrue dividend equivalents associated with the underlying stock as we declare dividends. Dividends will generally be paid 
to holders of PUs in cash upon the settlement date of the associated PU and will be forfeited if the PU does not vest.

During the years ended December 31, 2022, 2021 and 2020, we issued 435,675, 488,953 and 425,777 PUs, respectively. We 
forecast the likelihood of achieving the predefined targets for our PUs in order to calculate the expected PUs to be earned. We 
record a compensation charge based on either the forecasted PUs to be earned (during the performance period) or the actual PUs 
earned (at the three-year anniversary of the grant date) over the vesting period for each of the awards. The fair value of PUs based 
on our performance against predefined targets is the excess of the market price of our common stock at the date of grant over the 
purchase price (which is typically zero). For PUs earned based on a market condition, we utilize a Monte Carlo simulation to fair 
value these awards at the date of grant, and such fair value is expensed over the three-year performance period. 

The fair value of earned PUs that vested during the years ended December 31, 2022, 2021 and 2020, is as follows:

EMPLOYEE STOCK PURCHASE PLAN

We offer an Employee Stock Purchase Plan ("ESPP") in which participation is available to substantially all United States and 
Canadian employees who meet certain service eligibility requirements. Shares of our common stock may be purchased by eligible 
employees at six-month intervals at 95% of the fair market price at the end of each six-month period, without a look-back feature, 
up to a maximum of 15% of their gross compensation during the offering period. We do not recognize compensation expense for 
the ESPP shares purchased. In May 2021, our stockholders approved an amendment to the ESPP to increase the number of 
shares of Common Stock authorized for issuance thereunder from 1,000,000 to 2,000,000. For the years ended December 31, 
2022, 2021 and 2020, there were 112,486, 112,297 and 159,853 shares, respectively, purchased under the ESPP. As of 
December 31, 2022, we have 991,504 shares available under the ESPP.

As of December 31, 2022, unrecognized compensation cost related to the unvested portion of our Employee Stock-Based Awards 
was $49,455 and is expected to be recognized over a weighted-average period of 2.0 years.

We issue shares of our common stock for the exercises of stock options, and the vesting of RSUs, PUs and shares of our common 
stock under our ESPP from unissued reserved shares.

U. ACQUISITION AND INTEGRATION COSTS

Acquisition and integration costs represent operating expenditures directly associated with the closing and integration activities of 
our business acquisitions that have closed, or are highly probable of closing, and include (i) advisory, legal and professional fees to 
complete business acquisitions and (ii) costs to integrate acquired businesses into our existing operations, including move, 
severance and system integration costs (collectively, "Acquisition and Integration Costs"). Acquisition and integration costs for the 
year ended December 31, 2022, 2021 and 2020 were $47,746, $12,764 and $0, respectively.

Netherlands subsidiaries, for which we had value-added tax liability exposure that was recorded in 2019, partially offset by (iii) losses on our equity method 
investments.

W. INCOME TAXES

Accounting for income taxes requires the recognition of deferred tax assets and liabilities for the expected future tax consequences 
of temporary differences between the tax and financial reporting bases of assets and liabilities and for loss and credit 
carryforwards. Valuation allowances are provided when recovery of deferred tax assets does not meet the more likely than not 
standard as defined in GAAP. We have elected to recognize interest and penalties associated with uncertain tax positions as a 
component of the Provision (benefit) for income taxes in the accompanying Consolidated Statements of Operations.

X. INCOME (LOSS) PER SHARE—BASIC AND DILUTED

Basic income (loss) per common share is calculated by dividing income (loss) by the weighted average number of common shares 
outstanding. The calculation of diluted income (loss) per share is consistent with that of basic income (loss) per share but gives 
effect to all potential common shares (that is, securities such as stock options, RSUs, PUs, warrants or convertible securities) that 
were outstanding during the period, unless the effect is antidilutive. 

The calculation of basic and diluted income (loss) per share for the years ended December 31, 2022, 2021 and 2020 is as follows:

Y. NEW ACCOUNTING PRONOUNCEMENTS

NOT YET ADOPTED ACCOUNTING PRONOUNCEMENTS

In December 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 
2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with 
Customers ("ASU 2021-08"). ASU 2021-08 requires that an entity recognize and measure contract assets and contract liabilities 
acquired in a business combination in accordance with ASU 2014-09 and for the related revenue contracts in accordance with ASU 
2014-09 as if it had originated the contracts. ASU 2021-08 will be effective for us on January 1, 2023, with early adoption permitted. 
We do not expect ASU 2021-08 to have a material impact on our consolidated financial statements upon its adoption.

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) ("ASU 2020-04"). ASU 2020-04 provides 
optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions, for a limited 
period of time, to ease the potential burden of recognizing the effects of reference rate reform on financial reporting. The 
amendments in ASU 2020-04 apply to contracts, hedging relationships and other transactions that reference the London Inter-Bank 
Offered Rate ("LIBOR") or another reference rate expected to be discontinued due to the global transition away from LIBOR and 
certain other interbank offered rates. Under ASU 2020-04, an entity could elect to apply the amendments beginning March 12, 
2020 through December 31, 2022. In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848), 
Deferral of the Sunset Date of Topic 848 ("ASU 2022-06") to defer the sunset date of Topic 848 from December 31, 2022 to 
December 31, 2024, after which entities will no longer be permitted to apply the relief in Topic 848. We are currently evaluating 
these amendments as they relate to our contracts, hedging relationships and other transactions that reference LIBOR, as well as 
the impact of ASU 2020-04 and ASU 2022-06 on our consolidated financial statements, but we do not expect the impact to be 
material.

3. ACQUISITIONS

We account for acquisitions using the acquisition method of accounting, and, accordingly, the assets and liabilities acquired are 
recorded at their estimated fair values and the results of operations for each acquisition have been included in our consolidated 
results from their respective acquisition dates. 

A. ACQUISITIONS COMPLETED DURING THE YEAR ENDED DECEMBER 31, 2022  

ITRENEW

On January 25, 2022, in order to expand our ALM operations, we acquired an approximately 80% interest in ITRenew at an agreed 
upon purchase price of $725,000, subject to certain working capital adjustments at, and subsequent to, the closing (the "ITRenew 
Transaction"). At closing, we paid $748,846 and acquired $30,720 of cash on hand, for a net purchase price of $718,126 for the 
ITRenew Transaction. The acquisition agreement provides us the option to purchase, and provides the shareholders of ITRenew 
the option to sell, the remaining approximately 20% interest in ITRenew as follows: (i) approximately 16% on or after the second 
anniversary of the ITRenew Transaction and (ii) approximately 4% on or after the third anniversary of the ITRenew Transaction 
(collectively, the "Remaining Interests"). The total payments for the Remaining Interests, based on the achievement of certain 
targeted performance metrics, will be no less than $200,000 and no more than $531,000 (the "Deferred Purchase Obligation"). 
From January 25, 2022, we consolidate 100% of the revenues and expenses associated with this business. The Deferred 
Purchase Obligation is reflected as a long-term liability in our Consolidated Balance Sheet at December 31, 2022, and, accordingly, 
we have not reflected any non-controlling interests associated with the ITRenew Transaction as the Remaining Interests have non-
substantive equity interest rights. Subsequent increases or decreases in the fair value estimate of the Deferred Purchase 
Obligation are included as a component of Other (income) expense, net in our Consolidated Statements of Operations until the 
Deferred Purchase Obligation is settled or paid. See Note 2.v.

PRO FORMA FINANCIAL INFORMATION 

The unaudited consolidated pro forma financial information (the "Pro Forma Financial Information") below summarizes the 
combined results of Iron Mountain and ITRenew on a pro forma basis as if the ITRenew Transaction had occurred on January 1, 
2021. The Pro Forma Financial Information is presented for informational purposes and is not necessarily indicative of the results 
of operations that would have been achieved if the acquisition had taken place on January 1, 2021. The Pro Forma Financial 
Information, for the periods presented, includes purchase accounting adjustments (including amortization of acquired customer and 
supplier intangible assets and depreciation of acquired property, plant and equipment) and related tax effects. Through December 
31, 2022, we and ITRenew collectively incurred $59,370 of operating expenditures to complete the ITRenew Transaction (including 
advisory and professional fees). These operating expenditures have been reflected within the results of operations in the Pro 
Forma Financial Information as if they were incurred on January 1, 2021.

In addition to our acquisition of ITRenew, we completed certain other acquisitions during the years ended December 2022, 2021 
and 2020. The Pro Forma Financial Information does not reflect these acquisitions due to the insignificant impact of these 
acquisitions on our consolidated results of operations.

XDATA PROPERTIES

On October 5, 2022, in order to further expand our data center operations in Europe, we completed the acquisition of XData 
Properties S.L.U., a data center colocation space and solutions provider with a data center in Spain, which we accounted for as an 
asset acquisition, for (i) cash consideration of 78,900 Euros (or approximately $78,200, based upon the exchange rate between the 
Euro and the United States dollar on the closing date of this acquisition), subject to adjustments, and (ii) up to 10,000 Euros (or

acquisition) of additional consideration, payable based on the achievement of certain power connection milestones through 
December 2024.

OTHER 2022 ACQUISITIONS

In addition to the transactions noted above, during the year ended December 31, 2022, in order to enhance our existing operations 
in Morocco and expand our fine arts operations in China - Hong Kong S.A.R. and North America, we completed the acquisition of a 
records management company, a fine arts company and the assets of a second fine arts company, for a total combined purchase 
price of approximately $11,600, including deferred purchase obligations, purchase price holdbacks and other deferred payments of 
approximately $4,600.

B. ACQUISITIONS COMPLETED DURING THE YEAR ENDED DECEMBER 31, 2021

On September 15, 2021, in order to further expand our records management operations in the Middle East and North Africa, we 
acquired Information Fort, LLC, a records and information management provider, for approximately $90,300.

On September 23, 2021, in order to further enhance our data center operations in Germany, we completed the acquisition of assets 
of a Frankfurt data center for approximately 77,900 Euros (or approximately $91,300, based upon the exchange rate between the 
Euro and the United States dollar on the closing date of this acquisition).

In addition to the transactions noted above, during the year ended December 31, 2021, in order to enhance our existing operations 
in the United Kingdom and Indonesia and to expand our operations into Morocco, we completed the acquisition of two records 
management companies and one art storage company for total cash consideration of approximately $45,100.

C. ACQUISITIONS COMPLETED DURING THE YEAR ENDED DECEMBER 31, 2020

Prior to January 9, 2020, we owned a 25% equity interest in OSG Records Management (Europe) Limited ("OSG"). On January 9, 
2020, we acquired the remaining 75% equity interest in OSG for cash consideration of approximately $95,500 (the "OSG 
Acquisition"). The OSG Acquisition enabled us to extend our Global RIM Business in Russia, Ukraine, Kazakhstan, Belarus, and 
Armenia. The results of OSG are fully consolidated within our consolidated financial statements from the closing date of the OSG 
Acquisition. In connection with the OSG Acquisition, our previously held 25% equity investment in OSG was remeasured to fair 
value at the closing date of the OSG Acquisition; as a result, we recorded a gain of approximately $10,000 during the first quarter of 
2020, which is included as a component of Other (income) expense, net in our Consolidated Statements of Operations. The fair 
value of the 25% equity investment in OSG was determined based on the purchase price of the OSG Acquisition. 

On February 17, 2020, in order to enhance our existing operations in the United Arab Emirates, we acquired Glenbeigh Records 
Management DWC-LLC, a storage and records management company, for total cash consideration of approximately $29,100.

In 2022, Deferred purchase obligation, purchase price holdbacks and other includes $275,100 related to the original fair value estimate of the Deferred Purchase 
Obligation for the Remaining Interests and approximately $13,600 of deferred purchase obligation, purchase price holdbacks and other associated with our other 
business and asset acquisitions completed in 2022.

(3) The weighted average lives of customer and supplier relationship intangible assets associated with acquisitions in 2022, 2021 and 2020 was 12 years, 11 years and 

14 years, respectively.

(4) The weighted average lives of data center Iease-based intangible assets associated with acquisitions in 2022 and 2021 was four years and five years, respectively.

(5) The weighted average lives of other intangible assets associated with acquisitions in 2022 was five years.

Allocations of the purchase price for acquisitions are based on estimates of the fair value of the net assets acquired and are subject 
to adjustment upon the finalization of the purchase price allocations. The accounting for business combinations requires estimates 
and judgments regarding expectations for future cash flows of the acquired business, and the allocations of those cash flows to 
identifiable tangible and intangible assets, in determining the assets acquired and liabilities assumed. The fair values assigned to 
tangible and intangible assets acquired and liabilities assumed, including contingent consideration, are based on management’s 
best estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary 
valuation procedures and techniques. The estimates and assumptions underlying the initial valuations are subject to the collection 
of information necessary to complete the valuations within the measurement periods, which are up to one year from the respective 
acquisition dates.

3. ACQUISITIONS (CONTINUED)

As the valuation of certain assets and liabilities for purposes of purchase price allocations are preliminary in nature, they are 
subject to adjustment as additional information is obtained about the facts and circumstances regarding these assets and liabilities 
that existed at the acquisition date. Any adjustments to our estimates of purchase price allocation will be made in the periods in 
which the adjustments are determined and the cumulative effect of such adjustments will be calculated as if the adjustments had 
been completed as of the acquisition dates. Purchase price allocation adjustments recorded during the fourth quarter of 2022 and 
year ended December 31, 2022 were not material to our balance sheet or results from operations.

4. DIVESTMENTS AND DECONSOLIDATIONS

OSG RECORDS MANAGEMENT (EUROPE) LIMITED DECONSOLIDATION

On March 24, 2022, as a result of our loss of control, we deconsolidated the businesses included in our acquisition of OSG, 
excluding Ukraine ("OSG Deconsolidation"). We recognized a loss of approximately $105,800 associated with the deconsolidation 
to Other (income) expense, net in the first quarter of 2022 representing the difference between the net asset value prior to the 
deconsolidation and the subsequent remeasurement of the retained investment to a fair value of zero. We have concluded that the 
deconsolidation does not meet the criteria to be reported as discontinued operations in our consolidated financial statements, as it 
does not represent a strategic shift that will have a major effect on our operations and financial results. Accordingly, the revenues 
and expenses associated with these businesses are presented as a component of Operating income (loss) in our Consolidated 
Statements of Operations through the date of deconsolidation and the cash flows associated with these businesses are presented 
as a component of Cash flows from operations in our Consolidated Statements of Cash Flows through the date of the 
deconsolidation. 

INTELLECTUAL PROPERTY MANAGEMENT BUSINESS DIVESTMENT

On June 7, 2021, we sold our Intellectual Property Management ("IPM") business, which we predominantly operated in the United 
States, for total gross consideration of approximately $215,400 (the "IPM Divestment"). As a result of the IPM Divestment, we 
recorded a gain on sale of approximately $179,000 to Other (income) expense, net during the year ended December 31, 2021, 
representing the excess of the fair value of the consideration received over the sum of the carrying value of the IPM business. We 
have concluded that the IPM Divestment does not meet the criteria to be reported as discontinued operations in our consolidated 
financial statements, as our decision to divest this business does not represent a strategic shift that will have a major effect on our 
operations and financial results.

5. INVESTMENTS

CLUTTER JOINT VENTURE

In February 2022, the joint venture formed by MakeSpace Labs, Inc. and us (the "MakeSpace JV") entered into an agreement with 
Clutter, Inc. ("Clutter") pursuant to which the equityholders of the MakeSpace JV contributed their ownership interests in the 
MakeSpace JV and Clutter’s shareholders contributed their ownership interests in Clutter to create a newly formed venture (the 
"Clutter JV"). In exchange for our 49.99% interest in the MakeSpace JV, we received an approximate 27% interest in the Clutter JV 
(the "Clutter Transaction"). As a result of the Clutter Transaction, we recognized a gain related to our contributed interest in the 
MakeSpace JV of approximately $35,800, which was recorded to Other, net, a component of Other expense (income), net during 
the year ended December 31, 2022.

5. INVESTMENTS

WEB WERKS JOINT VENTURE

In April 2021, we closed on an agreement to form a joint venture (the "Web Werks JV") with the shareholders of Web Werks India 
Private Limited ("Web Werks"), a colocation data center provider in India. In connection with the formation of the Web Werks JV, we 
made an initial investment of approximately 3,750,000 Indian rupees (or approximately $50,100, based upon the exchange rate 
between the United States dollar and Indian rupee on the closing date of the initial investment) in exchange for a noncontrolling 
interest in the form of convertible preference shares in the Web Werks JV (the "Initial Web Werks JV Investment"). In August 2022, 
we made an additional investment of approximately 3,750,000 Indian rupees (or approximately $46,100, based upon the exchange 
rate between the United States dollar and Indian rupee on the date of the additional investment) in exchange for an additional 
interest in the form of convertible preference shares in the Web Werks JV (the "Second Web Werks JV Investment"). Under the 
terms of the Web Werks JV shareholder agreement, we are required to make an additional investment of approximately 3,750,000 
Indian rupees by May 2023. The shares we received from the Initial Web Werks JV Investment and the Second Web Werks JV 
Investment converted to 382,574 equity shares, representing a 53.58% ownership in the JV as of December 31, 2022, determined 
by a valuation based upon the earnings before interest, taxes, depreciation and amortization ("EBITDA") of the Web Werks JV for 
the trailing twelve months ending July 31, 2022. Subsequent to the Second Web Werks JV Investment, the shareholders of Web 
Werks retained control of the financial and operating decisions of the Web Werks JV through their control of Web Werks JV's board 
of directors. As we do not control the board of directors or the key management decisions of the Web Werks JV, we account for our 
interest in the Web Werks JV as an equity method investment.

FRANKFURT JOINT VENTURE

In October 2020, we formed a joint venture (the "Frankfurt JV") with AGC Equity Partners ("AGC") to design and develop a 280,000 
square foot, 27 megawatt, hyperscale data center, which is currently under development in Frankfurt, Germany (the "Frankfurt JV 
Transaction"). AGC acquired an 80% equity interest in the Frankfurt JV, while we retained a 20% equity interest (the "Frankfurt JV 
Investment"). The total cash consideration for the 80% equity interest sold to AGC was approximately $105,000. We received 
approximately $93,300 (gross of certain transaction expenses) upon the closing of the Frankfurt JV, and we are entitled to receive 
an additional approximately $11,700 upon the completion of development of the data center, which we expect to occur in the first 
quarter of 2023. In connection with the Frankfurt JV Transaction, we also entered into agreements whereby we will earn various 
fees, including property management and construction and development fees, for services we are providing to the Frankfurt JV. 

As a result of the Frankfurt JV Transaction, we recognized a gain during the year ended December 31, 2020 of approximately 
$24,100, representing the excess of the fair value of the consideration received over the carrying value of the assets, which 
consisted primarily of land and land development assets which were previously included within our Global Data Center Business 
segment. 

JOINT VENTURE SUMMARY

The joint ventures referred to above are accounted for as equity method investments and are presented as a component of Other 
within Other assets, net in our Consolidated Balance Sheets. The carrying values and equity interests in our joint ventures at

6. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Derivative instruments we are party to include: (i) interest rate swap agreements (which are designated as cash flow hedges) and 
(ii) cross-currency swap agreements (which are designated as net investment hedges).

INTEREST RATE SWAP AGREEMENTS DESIGNATED AS CASH FLOW HEDGES

In November 2022, we entered into a forward-starting interest rate swap agreement to limit our exposure to changes in interest 
rates on future borrowings under our Virginia Credit Agreement (as defined in Note 7). The forward-starting interest rate swap 
agreement commences in July 2023 and expires in October 2025 (the "October 2025 Interest Rate Swap Agreement"). The 
October 2025 Interest Rate Swap Agreement has an initial notional value of $4,800, which is contracted to increase in monthly 
increments beginning in August 2023 to June 2025 to a total notional value of $153,800. Under the October 2025 Interest Rate 
Swap Agreement, we will receive variable rate interest payments based upon SOFR, in exchange for the payment of a fixed 
interest rate as specified in the October 2025 Interest Rate Swap Agreement.

In March 2018, we entered into interest rate swap agreements to limit our exposure to changes in interest rates on a portion of our 
floating rate indebtedness. These swap agreements expired in March 2022. In July 2019, we entered into forward-starting interest 
rate swap agreements to limit our exposure to changes in interest rates on a portion of our floating rate indebtedness. These 
forward-starting interest rate swap agreements commenced in March 2022. As of December 31, 2022 we have $350,000 in 
notional value outstanding on these interest rate swap agreements, which expire in March 2024 (the "March 2024 Interest Rate 
Swap Agreements"). Under the March 2024 Interest Rate Swap Agreements, we receive variable rate interest payments associated 
with the notional amount of each interest rate swap, based upon one-month LIBOR, in exchange for the payment of fixed interest 
rates as specified in the March 2024 Interest Rate Swap Agreements.

We have designated each of the interest rate swap agreements described above as cash flow hedges. These interest rate swap 
agreements are marked to market at the end of each reporting period, representing the fair values of the interest rate 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, while unrealized losses are recognized as liabilities. 

CROSS-CURRENCY SWAP AGREEMENTS DESIGNATED AS A HEDGE OF NET 
INVESTMENT

In August 2019, we entered into cross-currency swap agreements to hedge the variability of exchange rate impacts between the 
United States dollar and the Euro. Under the terms of the cross-currency swap agreements, we notionally exchanged $110,000 at 
an interest rate of 6.0% for approximately 99,055 Euros at a weighted average interest rate of approximately 3.65%. These cross-
currency swap agreements expire in August 2023 (the "August 2023 Cross Currency Swap Agreements"). In October 2022, one of 
these August 2023 Cross Currency Swap Agreements was amended to increase the notional value exchanged from approximately 
49,500 Euros at an interest rate of 3.6% to approximately 55,466 Euros at an interest rate of (9.5%), resulting in a total notional 
value exchanged under the August 2023 Cross Currency Swap Agreements of approximately 105,020 Euros at a weighted average 
interest rate of approximately (3.3%).

In September 2020, we entered into cross-currency swap agreements to hedge the variability of exchange rate impacts between 
the United States dollar and the Euro. Under the terms of these cross-currency swap agreements, we notionally exchanged 
approximately $359,200 at an interest rate of 4.5% for 300,000 Euros at a weighted average interest rate of approximately 3.4%. 
These cross-currency swap agreements expire in February 2026 (the "February 2026 Cross Currency Swap Agreements"). In May 
2022, the February 2026 Cross-Currency Swap Agreements were amended to increase the notional value exchanged to 
approximately 340,500 Euros at a weighted average interest rate of approximately 1.2%. In October 2022, the February 2026 
Cross-Currency Swap Agreements were further amended to increase the notional value exchanged to approximately 362,083 
Euros at a weighted average interest rate of approximately 0.2%.

6. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

We have designated these cross-currency swap agreements as hedges of net investments in certain of our Euro denominated 
subsidiaries and they 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 while unrealized losses are recognized as liabilities. The excluded component of our cross-currency swap 
agreements is recorded in Accumulated other comprehensive items, net and amortized to interest expense on a straight-line basis.

Net assets (liabilities) recognized in our Consolidated Balance Sheets as of December 31, 2022 and 2021, by derivative 
instrument, are as follows:

EURO NOTES DESIGNATED AS A HEDGE OF NET INVESTMENT 

Prior to their redemption in August 2020, we designated a portion of our Euro Notes as a hedge of net investment of certain of our 
Euro denominated subsidiaries. From January 1, 2020 through the date of redemption we designated, on average, 300,000 Euros, 
of our Euro Notes as a hedge of net investment of certain of our Euro denominated subsidiaries. As a result, for the year ended 
December 31, 2020, we recorded a foreign exchange loss of $17,005 related to the change in fair value of such debt due to 
currency translation adjustments as a component of Accumulated other comprehensive items, net. As of December 31, 2022, 
cumulative net gains of $3,256, net of tax, are recorded in Accumulated other comprehensive items, net associated with this net 
investment hedge.

A. CREDIT AGREEMENT

Our credit agreement (the "Credit Agreement") consists of a revolving credit facility (the "Revolving Credit Facility"), a term loan A 
(the "Term Loan A") and a term loan B (the "Term Loan B"). On March 18, 2022, we entered into an amendment to the Credit 
Agreement which included the following changes:

(i) extended the maturity date of the Revolving Credit Facility and the Term Loan A from June 3, 2023 to March 18, 2027;

(ii) refinanced and increased the borrowing capacity that IMI and certain of its United States and foreign subsidiaries are 
able to borrow under the Revolving Credit Facility from $1,750,000 to $2,250,000;

(iii) refinanced the existing Term Loan A with a new $250,000 Term Loan A; and

(iv) increased the net total lease adjusted leverage ratio maximum allowable from 6.5x to 7.0x and removed the net 
secured lease adjusted leverage ratio requirement.

The Revolving Credit Facility enables IMI and certain of its subsidiaries to borrow in United States dollars and (subject to sublimits) 
Canadian dollars in an aggregate outstanding amount not to exceed $2,250,000. Additionally, the Credit Agreement permits us to 
incur incremental indebtedness thereunder by adding new term loans or revolving loans or by increasing the principal amount of 
any existing loans thereunder. The Revolving Credit Facility and the Term Loan A are scheduled to mature on March 18, 2027, at 
which point all obligations become due. On March 18, 2022, we borrowed the full amount of the Term Loan A of $250,000. The 
Term Loan A is to be paid in quarterly installments in an amount equal to $3,125 per quarter. IMI’s wholly owned subsidiary, Iron 
Mountain Information Management, LLC ("IMIM"), is the borrower under the Term Loan B, which has a principal amount of 
$700,000. The Term Loan B, which matures on January 2, 2026, was issued at 99.75% of par. Principal payments on the Term 
Loan B are to be paid in quarterly installments of $1,750.

7. DEBT (CONTINUED)

IMI and certain subsidiaries of IMI that represent the substantial majority of our operations in the United States, Canada and the 
United Kingdom guarantee all obligations under the Credit Agreement. The interest rate on borrowings under the Revolving Credit 
Facility varies depending on our choice of interest rate benchmark and currency options, plus an applicable margin, which varies 
based on our consolidated leverage ratio. The Term Loan A bears interest at the Secured Overnight Financing Rate ("SOFR") plus 
a credit spread adjustment of 0.1% plus 1.75%. The Term Loan B bears interest at a rate of LIBOR plus 1.75%. Additionally, the 
Credit Agreement requires the payment of a commitment fee on the unused portion of the Revolving Credit Facility, which fee 
ranges from 0.2% to 0.3% based on our consolidated leverage ratio. 

As of December 31, 2022, we had $1,072,200, $240,625 and $666,073 outstanding under the Revolving Credit Facility, the Term 
Loan A and the Term Loan B, respectively. At December 31, 2022, we had various outstanding letters of credit totaling $3,824 
under the Revolving Credit Facility. The remaining amount available for borrowing under the Revolving Credit Facility as of 
December 31, 2022, which is based on IMI’s leverage ratio, the last 12 months' earnings before interest, taxes, depreciation and 
amortization and rent expense ("EBITDAR"), other adjustments as defined in the Credit Agreement and current external debt, was 
$1,173,976 (which amount represents the maximum availability as of such date). Available borrowings under the Revolving Credit 
Facility are subject to compliance with our indenture covenants as discussed below. The weighted average interest rate in effect 
under the Revolving Credit Facility as of December 31, 2022 was 6.2%. The interest rate in effect under the Term Loan A as of 
December 31, 2022 and 2021 was 6.2% and 1.9%, respectively. The interest rate in effect under the Term Loan B as of 
December 31, 2022 and 2021 was 4.8% and 3.1%, respectively.

B. VIRGINIA CREDIT AGREEMENT

On October 31, 2022, Iron Mountain Data Centers Virginia 4/5 Subsidiary, LLC, a wholly owned subsidiary of Iron Mountain Data 
Centers Virginia 4/5 JV, LP, entered into a credit agreement (the "Virginia Credit Agreement") in order to finance the construction of 
two data center facilities in Virginia. The Virginia Credit Agreement consists of a term loan and a letter of credit facility with the first 
borrowing under the term loan expected to occur in the third quarter of 2023. Borrowings under the Virginia Credit Agreement are 
guaranteed by Iron Mountain Data Centers Virginia 4/5 JV, LP, a special purpose vehicle, and not by IMI or any other subsidiary of 
IMI. We have the option to borrow, in the form of term loans, an aggregate outstanding amount not to exceed approximately 
$205,000. At December 31, 2022, we had approximately $6,400 in outstanding letters of credit under the Virginia Credit 
Agreement. The Virginia Credit Agreement requires the payment of a commitment fee on any unused commitments at a rate of 
0.4875%. We have the option to select between various base rates for any given borrowing under the Virginia Credit Agreement, 
and the interest rate and applicable margin on such borrowings vary depending on the chosen base rate. The Virginia Credit 
Agreement is scheduled to mature on October 31, 2025, at which point all obligations will become due. We have two one-year 
options that allow us to extend the maturity date beyond the October 31, 2025 expiration date, subject to the conditions specified in 
the Virginia Credit Agreement, including the lender's consent. As of December 31, 2022, we have no outstanding borrowings under 
the Virginia Credit Agreement.

Revolving Credit Facility (the "UK Bilateral Revolving Credit Facility") with Barclays Bank PLC. The maximum amount permitted to 
be borrowed under the UK Bilateral Revolving Credit Facility is 140,000 British pounds sterling. We have the option to request 
additional commitments of up to 125,000 British pounds sterling, subject to conditions specified in the UK Bilateral Revolving Credit 
Facility. The UK Bilateral Revolving Credit Facility is secured by certain properties in the United Kingdom. IMI and subsidiaries of 
IMI that represent the substantial majority of our operations in the United States and the United Kingdom guarantee all obligations 
under the UK Bilateral Revolving Credit Facility. The UK Bilateral Revolving Credit Facility bears interest at the Sterling Overnight 
Index Average plus 2.0%. 

The UK Bilateral Revolving Credit Facility was previously scheduled to mature on 
September 24, 2023, at which point all obligations were to become due, with the option 
to extend the maturity date for an additional year, subject to the conditions specified in 
the UK Bilateral Revolving Credit Facility, including the lender’s consent. On September

F. ACCOUNTS RECEIVABLE SECURITIZATION PROGRAM 

We participate in an accounts receivable securitization program (the "Accounts Receivable Securitization Program") involving 
several of our wholly owned subsidiaries and certain financial institutions. Under the Accounts Receivable Securitization Program, 
certain of our subsidiaries sell substantially all of their United States accounts receivable balances to our wholly owned special 
purpose entities, Iron Mountain Receivables QRS, LLC and Iron Mountain Receivables TRS, LLC (the "Accounts Receivable 
Securitization Special Purpose Subsidiaries"). The Accounts Receivable Securitization Special Purpose Subsidiaries use the 
accounts receivable balances to collateralize loans obtained from certain financial institutions. The Accounts Receivable 
Securitization Special Purpose Subsidiaries are consolidated subsidiaries of IMI. The Accounts Receivable Securitization Program 
is accounted for as a collateralized financing activity, rather than a sale of assets, and therefore: (i) accounts receivable balances 
pledged as collateral are presented as assets and borrowings are presented as liabilities on our Consolidated Balance Sheets, (ii) 
our Consolidated Statements of Operations reflect the associated charges for bad debt expense related to pledged accounts 
receivable (a component of selling, general and administrative expenses) and reductions to revenue due to billing and service 
related credit memos issued to customers and related reserves, as well as interest expense associated with the collateralized 
borrowings and (iii) receipts from customers related to the underlying accounts receivable are reflected as operating cash flows and 
borrowings and repayments under the collateralized loans are reflected as financing cash flows within our Consolidated Statements 
of Cash Flows. IMIM retains the responsibility of servicing the accounts receivable balances pledged as collateral for the Accounts 
Receivable Securitization Program and IMI provides a performance guaranty. The maximum availability allowed is limited by 
eligible accounts receivable, as defined under the terms of the Accounts Receivable Securitization Program. 

On June 29, 2022, we amended the Accounts Receivable Securitization Program to (i) 
increase the maximum borrowing capacity from $300,000 to $325,000, with an option 
to increase the borrowing capacity to $400,000, (ii) change the interest rate under 
Accounts Receivable Securitization Program from LIBOR plus 1.0% to SOFR plus 
0.95%, with a credit spread adjustment of 0.10% and (iii) extend the maturity date from

G. CASH POOLING

Certain of our subsidiaries participate in cash pooling arrangements (the "Cash Pools") to help manage global liquidity 
requirements. We utilize the following Cash Pools: (i) two Cash Pools with Bank Mendes Gans, an independently operated wholly 
owned subsidiary of ING Group, one of which we use to manage global liquidity requirements for our qualified REIT subsidiaries 
("QRSs") and the other for our taxable REIT subsidiaries ("TRSs"); (ii) two Cash Pools with JP Morgan Chase Bank, N.A. ("JPM"), 
one of which we use to manage liquidity requirements for our QRSs in the Asia Pacific region and the other for our TRSs in the 
Asia Pacific region; and (iii) two Cash Pools with JPM, which we entered into in the third quarter of 2022, one of which we use to 
manage liquidity requirements for our QRSs in the Europe, Middle East, and Africa regions and the other for our TRSs in the 
Europe, Middle East, and Africa regions. 

Under each of the Cash Pools, cash deposited by participating subsidiaries with certain financial institutions is pledged as security 
against the debit balances of other participating subsidiaries with legal rights of offset provided to the financial institutions, and, 
therefore, such amounts are presented in our Consolidated Balance Sheets on a net basis. Each subsidiary receives interest on 
the cash balances held on deposit or pays interest on its debit balances based on an applicable rate as defined in the Cash Pools.

The net cash position balances as of December 31, 2022 and 2021 are reflected as Cash and cash equivalents in our 
Consolidated Balance Sheets. 

H. LETTERS OF CREDIT

As of December 31, 2022, we had outstanding letters of credit totaling $39,795, of which $3,824 reduce our borrowing capacity 
under the Revolving Credit Facility (as described above). The letters of credit expire at various dates between January 2023 and 
March 2025.

I. DEBT COVENANTS

The Credit Agreement, our bond indentures and other agreements governing our indebtedness contain certain restrictive financial 
and operating covenants, including covenants that restrict our ability to complete acquisitions, pay cash dividends, incur 
indebtedness, make investments, sell assets and take other specified corporate actions. The covenants do not contain a rating 
trigger. Therefore, a change in our debt rating would not trigger a default under the Credit Agreement, our bond indentures or other 
agreements governing our indebtedness. The Credit Agreement requires that we satisfy a net total lease adjusted leverage ratio 
and a fixed charge coverage ratio on a quarterly basis and our bond indentures require that, among other things, we satisfy a 
leverage ratio (not lease adjusted) or a fixed charge coverage ratio (not lease adjusted), as a condition to taking actions such as 
paying dividends and incurring indebtedness. 

The Credit Agreement uses EBITDAR-based calculations and the bond indentures use EBITDA-based calculations as the primary 
measures of financial performance for purposes of calculating leverage and fixed charge coverage ratios. The EBITDAR- and 
EBITDA-based leverage calculations include our consolidated subsidiaries, other than those we have designated as "Unrestricted 
Subsidiaries" as defined in the Credit Agreement and bond indentures. Generally, the Credit Agreement and the bond indentures 
use a trailing four fiscal quarter basis for purposes of the relevant calculations and require certain adjustments and exclusions for 
purposes of those calculations, which make the calculation of financial performance for purposes of those calculations under the 
Credit Agreement and bond indentures not directly comparable to Adjusted EBITDA as presented herein. We are in compliance 
with our leverage and fixed charge coverage ratios under the Credit Agreement, our bond indentures and other agreements 
governing our indebtedness as of December 31, 2022. Noncompliance with these leverage and fixed charge coverage ratios would 
have a material adverse effect on our financial condition.

B. SELF-INSURED LIABILITIES

We are self-insured up to certain limits for costs associated with workers’ compensation claims, vehicle accidents, property and 
general business liabilities, and benefits paid under employee healthcare and short-term disability programs. At December 31, 
2022 and 2021, there were $46,663 and $46,797, respectively, of self-insurance accruals reflected in Accrued expenses on our 
Consolidated Balance Sheets. The measurement of these costs requires the consideration of historical cost experience and 
judgments about the present and expected levels of cost per claim. We account for these costs primarily through actuarial 
methods, which develop estimates of the undiscounted liability for claims incurred, including those claims incurred but not reported. 
These methods provide estimates of future claim costs based on claims incurred as of the balance sheet date.

C. LITIGATION—GENERAL

We are involved in litigation from time to time in the ordinary course of business, including litigation arising from damage to 
customer assets in our facilities caused by fires and other natural disasters. 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. Our policy is to establish reserves for loss contingencies when the losses are both probable and 
reasonably estimable. We record legal costs associated with loss contingencies as expenses in the period in which they are 
incurred. While the outcome of litigation is inherently uncertain, we do not believe any current litigation will have a material adverse 
effect on our consolidated financial condition, results of operations or cash flows. We have estimated a reasonably possible range 
for all loss contingencies and believe it is reasonably possible that we could incur aggregate losses in addition to amounts currently 
accrued for all matters up to an additional $21,500 over the next several years. 

9. STOCKHOLDERS’ EQUITY MATTERS 

Our board of directors has adopted a dividend policy under which we have paid, and in the future intend to pay, quarterly cash 
dividends on our common stock. The amount and timing of future dividends will continue to be subject to the approval of our board 
of directors, in its sole discretion, and to applicable legal requirements.

9. STOCKHOLDERS’ EQUITY MATTERS (CONTINUED)

During the years ended December 31, 2022, 2021 and 2020, we declared dividends in an aggregate and per share amount, based 
on the weighted average number of common shares outstanding during each respective year, as follows:

For federal income tax purposes, distributions to our stockholders are generally treated as nonqualified ordinary dividends 
(potentially eligible for the lower effective tax rates available for "qualified REIT dividends"), qualified ordinary dividends or return of 
capital. The United States Internal Revenue Service requires historical C corporation earnings and profits to be distributed prior to 
any REIT distributions, which may affect the character of each distribution to our stockholders, including whether and to what extent 
each distribution is characterized as a qualified or nonqualified ordinary dividend. In addition, certain of our distributions qualify as 
capital gain distributions. For the years ended December 31, 2022, 2021 and 2020, the dividends we paid on our common shares 
were classified as follows:

Dividends paid during the years ended December 31, 2022, 2021 and 2020 which were classified as qualified ordinary dividends 
for federal income tax purposes primarily related to the distribution of historical C corporation earnings and profits related to certain 
acquisitions completed during the years ended December 31, 2022, 2021 and 2020. In 2022, the percentage of our dividend that 
was classified as a capital gain was 9.6% and was primarily related to the sale of land and buildings in the United States and 
Canada. In 2021, the percentage of our dividend that was classified as a capital gain was 21.8% and primarily related to the sale of 
land and buildings in the United States and the United Kingdom. In 2020, the percentage of our dividend that was classified as a 
capital gain was 49.5% and primarily related to the sale of land and buildings in the United States.

10. INCOME TAXES

We have been organized and have operated as a REIT effective beginning with our taxable year that ended on December 31, 
2014. As a REIT, we are generally permitted to deduct from our federal taxable income the dividends we pay to our stockholders. 
The income represented by such dividends is not subject to federal taxation at the entity level but is taxed, if at all, at the 
stockholder level. The income of our domestic TRSs, which hold our domestic operations that may not be REIT-compliant as 
currently operated and structured, is subject, as applicable, to federal and state corporate income tax. In addition, we and our 
subsidiaries continue to be subject to foreign income taxes in other jurisdictions in which we have business operations or a taxable 
presence, regardless of whether assets are held or operations are conducted through subsidiaries disregarded for federal income 
tax purposes or TRSs. We will also be subject to a separate corporate income tax on any gains recognized on the sale or 
disposition of any asset previously owned by a C corporation during a five-year period after the date we first owned the asset as a 
REIT asset that are attributable to "built-in gains" with respect to that asset on that date. We will also be subject to a built-in gains 
tax on our depreciation recapture recognized into income as a result of accounting method changes in connection with our 
acquisition activities. If we fail to remain qualified for taxation as a REIT, we will be subject to federal income tax at regular 
corporate income tax rates. Even if we remain qualified for taxation as a REIT, we may be subject to some federal, state, local and 
foreign taxes on our income and property in addition to taxes owed with respect to our TRS operations. In particular, while state 
income tax regimes often parallel the federal income tax regime for REITs, many states do not completely follow federal rules and 
some do not follow them at all.

The significant components of our deferred tax assets and deferred tax liabilities as of December 31, 2022 and 2021 are presented 
below:

Deferred Tax Assets:

Accrued liabilities and other adjustments

Net operating loss carryforwards

At December 31, 2022, we have federal net operating loss carryforwards of $63,497, which can be carried forward indefinitely, of 
which $57,132 is expected to be realized to reduce future federal taxable income. We have assets for foreign net operating losses 
of $81,872, with various expiration dates (and in some cases no expiration date), subject to a valuation allowance of approximately 
56.0%. If actual results differ unfavorably from certain of our estimates used, we may not be able to realize all or part of our net 
deferred income tax assets and additional valuation allowances may be required. Although we believe our estimates are 
reasonable, no assurance can be given that our estimates reflected in the tax provisions and accruals will equal our actual results. 
These differences could have a material impact on our income tax provision and operating results in the period in which such 
determination is made.

Our effective tax rates for the years ended December 31, 2022, 2021 and 2020 were 11.0%, 28.0% and 7.9%, respectively. Our 
effective tax rate is subject to variability in the future due to, among other items: (i) changes in the mix of income between our 
QRSs and our TRSs, as well as among the jurisdictions in which we operate; (ii) tax law changes; (iii) volatility in foreign exchange 
gains and losses; (iv) the timing of the establishment and reversal of tax reserves; (v) our ability to utilize net operating losses that 
we generate and (vi) the taxability or deductibility of significant transactions.

The primary reconciling items between the federal statutory tax rate of 21.0% and our overall effective tax rate were:

2022
The benefits derived from the dividends paid 
deduction of $82,620 and the differences in 
the tax rates to which our foreign earnings 
are subject of $22,227. In addition, there 
were gains and losses recorded in Other 
(income) expense, net and Gain (loss) on 
disposal/write-down of property, plant and 
equipment, net during the period for which 
there were insignificant tax impacts.

YEAR ENDED DECEMBER 31,

2021
The benefit derived from the dividends paid 
deduction of $8,203 which was offset by (i) 
the impact of differences in the tax rates at 
which our foreign earnings are subject to, 
resulting in a tax provision of $9,856, and (ii) 
foreign withholding taxes of $23,654, which 
were either paid during the year or accrued, 
for the deferred tax liability for the U.S. tax 
impact of undistributed earnings of foreign 
TRSs that are no longer intended to be 
permanently reinvested outside the United 
States.

2020
The benefit derived from the dividends paid 
deduction of $60,378 and the impact of 
differences in the tax rates at which our 
foreign earnings are subject to, resulting in a 
tax provision of $9,472. 

As a REIT, we are entitled to a deduction for dividends paid, resulting in a substantial reduction of federal income tax expense. As a 
REIT, substantially all of our income tax expense will be incurred based on the earnings generated by our foreign subsidiaries and 
our domestic TRSs.

10. INCOME TAXES (CONTINUED)

During 2021, as a result of the enactment of a tax law and the closing of various acquisitions, we concluded that it is no longer our 
intention to reinvest our undistributed earnings of our foreign TRSs indefinitely outside the United States. As a REIT, future 
repatriation of incremental undistributed earnings of our foreign subsidiaries will not be subject to federal or state income tax, with 
the exception of foreign withholding taxes. However, such future repatriations may require distributions to our stockholders in 
accordance with REIT distribution rules, and any such distribution may then be taxable, as appropriate, at the stockholder level. We 
expect to provide for foreign withholding taxes on the current and future earnings of all of our foreign subsidiaries as the result of 
such reassessment.

The Organization for Economic Co-operation and Development (the "OECD"), an international association comprised of 38 
countries, including the United States, has issued proposals that change long-standing tax principles including on a global 
minimum tax initiative. On December 12, 2022, the European Union member states agreed to implement the OECD’s Base Erosion 
and Profit Shifting ("BEPS") 2.0 Pillar Two global corporate minimum tax rate of 15% on companies with revenues of at least 
$790,000, which would go into effect in 2024. Other countries are also actively considering changes to their tax laws to adopt 
certain parts of the OECD’s proposals. In December 2022, South Korea enacted new global minimum tax rules to align with OECD 
BEPS 2.0 Pillar Two. We will continue to monitor regulatory developments to assess potential impacts of OECD proposals on us.

The evaluation of an uncertain tax position is a two-step process. The first step is a recognition process whereby we determine 
whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals 
or litigation processes, based on the technical merits of the position. The second step is a measurement process whereby a tax 
position that meets the more likely than not recognition threshold is calculated to determine the amount of benefit to recognize in 
the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being 
realized upon ultimate settlement.

We have elected to recognize interest and penalties associated with uncertain tax positions as a component of the provision 
(benefit) for income taxes in the accompanying Consolidated Statements of Operations. We recorded increases of $90 and $823 
for gross interest and penalties for the years ended December 31, 2022 and 2021, respectively. We recorded a decrease of $1,499 
for gross interest and penalties for the years ended December 31, 2020. We had $6,635 and $6,805 accrued for the payment of 
interest and penalties as of December 31, 2022 and 2021, respectively.

A summary of tax years that remain subject to examination by major tax jurisdictions is as follows:

TAX YEARS

See Below

2019 to present

2015 to present

TAX JURISDICTION

United States—Federal and State

United Kingdom

Canada

The normal statute of limitations for United States federal tax purposes is three years from the date the tax return is filed; however, 
the statute of limitations may remain open for periods longer than three years in instances where a federal tax examination is in 
progress. The 2021, 2020 and 2019 tax years remain subject to examination for United States federal tax purposes as well as net 
operating loss carryforwards utilized in these years. The normal statute of limitations for state purposes is between three to five 
years. However, certain of our state statute of limitations remain open for periods longer than this when audits are in progress.

We are subject to income taxes in the United States and numerous foreign jurisdictions. We are subject to examination by various 
tax authorities in jurisdictions in which we have business operations or a taxable presence. We regularly assess the likelihood of 
additional assessments by tax authorities and provide for these matters as appropriate. As of December 31, 2022, we had $27,753 
of reserves related to uncertain tax positions, of which $24,671 and $3,082 is included in other long-term liabilities and deferred 
income taxes, respectively, in the accompanying Consolidated Balance Sheet. As of December 31, 2021, we had $27,772 of 
reserves related to uncertain tax positions, of which $24,627 and $3,145 is included in other long-term liabilities and deferred 
income taxes, respectively, in the accompanying Consolidated Balance Sheet. Although we believe our tax estimates are 
appropriate, the final determination of tax audits and any related litigation could result in changes in our estimates.

The reversal of these reserves of $27,753 as of December 31, 2022 will be recorded as a reduction of our income tax provision, if 
sustained. We believe that it is reasonably possible that an amount up to approximately $5,977 of our unrecognized tax positions 
may be recognized by the end of 2023 as a result of a lapse of statute of limitations or upon closing and settling significant audits in 
various worldwide jurisdictions.

to be indicative of our core operating results, specifically: 

EXCLUDED

• Acquisition and Integration Costs

• Other (income) expense, net

• Restructuring and other transformation

• Stock-based compensation expense

•

•

Intangible impairments

• COVID-19 Costs (as defined below)

(Gain) loss on disposal/write-down of property, plant and 
equipment, net (including real estate)

12. RELATED PARTY TRANSACTIONS

In October 2020, in connection with the Frankfurt JV Transaction, we entered into agreements whereby we earn various fees, 
including (i) special project revenue and (ii) property management and construction and development fees for services we are 
providing to the Frankfurt JV (the "Frankfurt JV Agreements").

In March 2019, in connection with the formation of the MakeSpace JV, we entered into a storage and service agreement with the 
MakeSpace JV to provide certain storage and related services to the MakeSpace JV (the "MakeSpace Agreement"). In February 
2022, in connection with the formation of the Clutter JV, we terminated the MakeSpace Agreement and entered into a storage and 
service agreement with the Clutter JV to provide certain storage and related services to the Clutter JV (the "Clutter Agreement").

Revenue recognized in the accompanying Consolidated Statements of Operations under these agreements for the years ended 
December 31, 2022, 2021 and 2020 is as follows (approximately):

13. RESTRUCTURING AND OTHER TRANSFORMATION

PROJECT MATTERHORN

In September 2022, we announced Project Matterhorn, our global program designed to accelerate the growth of our business. 
Project Matterhorn investments will focus on transforming our operating model to a global operating model. Project Matterhorn will 
focus 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 will be investing to accelerate growth and to capture a greater share of the 
large, global addressable markets in which we operate. We expect to incur approximately $150,000 in costs annually related to 
Project Matterhorn from 2023 through 2025. 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

In October 2019, we announced Project Summit, our global program designed to better position us for future growth and 
achievement of our strategic objectives. We expanded Project Summit during the first quarter of 2020 to include additional 
opportunities to streamline our business and operations, as well as accelerated the timing of certain opportunities previously 
identified. As of December 31, 2021, we completed Project Summit. As a result of the program, we simplified our global structure, 
rebalanced resources to focus on higher growth areas, realigned our management structure to create a more dynamic, agile 
organization, made investments to enhance the customer experience and leveraged new technology solutions that enabled us to 
modernize our service delivery model and more efficiently utilize our fleet, labor and real estate.  

The implementation of Project Summit resulted in total restructuring costs of approximately $450,000 that primarily consisted of: (i) 
employee severance costs; (ii) internal costs associated with the development and implementation of Project Summit initiatives; (iii) 
professional fees, primarily related to third party consultants who assisted with the design and execution of various initiatives as 
well as project management activities and (iv) system implementation and data conversion costs. 

Restructuring costs for Project Summit are included as a component of Restructuring and other transformation in the 
accompanying Consolidated Statements of Operations for the years ended December 31, 2021 and 2020, and from the inception 
of Project Summit through December 31, 2021 is as follows:

DECEMBER 31, 2022
(Dollars in thousands)

Schedule III - Schedule of Real Estate and Accumulated Depreciation ("Schedule III") reflects the cost and associated accumulated 
depreciation for the real estate facilities that are owned. The gross cost included in Schedule III includes the cost for land, land 
improvements, buildings, building improvements and racking. Schedule III does not reflect the 1,143 leased facilities in our real 
estate portfolio. In addition, Schedule III does not include any value for financing leases for property that is classified as land, 
buildings and building improvements in our consolidated financial statements.

The following table presents a reconciliation of the gross amount of real estate assets, as presented in Schedule III below, to the 
sum of the historical book value of land, buildings and building improvements, racking and construction in progress as disclosed in 
Note 2.i. to Notes to Consolidated Financial Statements as of December 31, 2022:
