This report represents our commitment to enhancing stakeholder awareness of our sustainability priorities and describes how
our performance is contributing to long-term value creation and a sustainable, responsible, and customer-centric business model.
Letter from our President and CEO
As I reflect on the past year, we have continued to navigate a complex and rapidly changing global landscape. From geopolitical tensions and economic shifts to the increasing frequency of extreme weather, our company, customers, and communities face significant challenges.
At Iron Mountain, we are driven every day by our purpose: to protect and elevate the power of our customers' work. We foster a culture of inclusion and belonging, which fuels innovation and supports our growth.
In these times, our commitment to operating responsibly-ensuring the safety of our Mountaineers and steadfastly pursuing our long-term sustainability goals-has never been more vital. I am incredibly proud that in 2025, we recorded our safest year on record in terms of both total recordable incident rate and lost time incident rate. This achievement underscores our core value of "owning safety and security" and our dedication to protecting each other and our customers' assets as if they were our own.
Expanding our solutions
We continue to scale our service offerings to help our customers achieve both their business and sustainability objectives. This includes broadening the reach of our Asset Lifecycle Management (ALM) business to address the interconnected challenges of data security, affordability, and sustainability.
Furthermore, as we embrace AI-led solutions and processes that drive value for our customers and shareowners, we remain dedicated to the highest standards of data privacy and ethical information governance.
Delivering on our commitments
We remain steadfast in our sustainability commitments. We continue to make progress toward our near-term emissions reduction and Net Zero by 2040 targets, which are validated by the Science Based Targets initiative (SBTi). To date, we have achieved a 16% reduction in greenhouse gas (GHG) emissions since our 2022 baseline. We are pioneering innovative strategies to accelerate this progress, such as deploying electric and hybrid mobile shred units (MSUs) and developing a concept-stage Battery Energy Storage System (BESS) for our data centers to enhance local grid resilience.
Collaborating with partners
Collaboration is key to securing a sustainable future. We are holding our suppliers to the same high standards we set for ourselves, recognizing they are an essential extension of our business. By expanding our supply chain due diligence and engaging critical partners, we reduce risk and support our climate targets.
This report provides a comprehensive overview of our progress and our aspirations for the future. We invite you to join us as we continue to climb higher, building a more resilient and sustainable world for everyone.
Yours sincerely,

About Iron Mountain
Our purpose
To protect and elevate the power of our customers' work
Every day, organizations generate more content, data, devices, documents, archives, and digital artifacts-adding complexity, not clarity. Most of it remains unseen, underused, and scattered across systems or lost in storage. In a world defined by speed and AI, progress doesn't come from more information but from unlocking the value in what already exists.
At Iron Mountain, we believe information has power when it's protected, connected, and activated. And we've been building on this belief for over 70 years as the trusted steward of the world's most valuable assets.
We help organizations of all sizes seamlessly manage their digital and physical assets across their lifecycle-making them visible, secure, accessible, and AI ready.
From payments to pathology, mortgages to media, fine art to IT-we are the trusted partner to 95% of the Fortune 1000 to unlock the value from what's already within reach. Transforming information into intelligence and assets into advantage.

Decarbonizing our operations
Greener fleet
Vehicles play an essential role in our operations. We depend on our fleet to deliver exceptional service to our customers worldwide. In 2025, vehicle emissions accounted for 41.9% of our Scope 1 and 2 greenhouse gas emissions, making our fleet a key focus area of our emissions-reduction strategy. We are taking action to achieve a 20% reduction of Scope 1 fleet emissions by 2030 from our 2022 baseline.
Innovation in mobile shred vehicles
Over the last several years, we have been investigating options to reduce emissions in our fleet operations. In 2025, we took the next step in this journey by evaluating solutions to reduce emissions from the idling of our mobile shred units (MSU) during onsite shredding services. We tested a prototype of a fully electric mobile shred unit and launched two hybrid units into service. This innovation is key to developing a more sustainable path for our fleet.
These next-generation MSUs offer tangible benefits for both our customers and the environment. Our onsite shredding customers appreciate the significantly quieter processing capabilities of these new units, which enhances their service experience while also reducing fossil fuel consumption. We look forward to continuing to work with the manufacturers on adjustments that would enable us to deploy these vehicles more broadly across our operations.
In 2025, 18% of our global light-duty fleet, including vans, trucks, and company cars, were electric and we increased the use of biofuels by 186% since 2022.
Our greener fleet focus areas include:
Fleet electrification | We now have over 335 electric vehicles in service, or on order, across 31 countries.

In 2025, Iron Mountain's Global Real Estate (GRE) team reached a major milestone in our onsite clean energy generation journey by successfully completing our first solar project in Thailand.
The 250 kilowatt-peak (kWp) solar system, installed at our IC1+IC2 facility in Soi Wat Nam Daeng, became operational in July. In its first two months alone, the installation generated approximately 55,000 kilowatt-hours (kWh) of clean power, successfully covering 33% of the site's energy needs. Beyond the environmental benefits, the project is projected to deliver approximately $44,000 in annual utility savings.
By retaining all environmental attributes generated by the system, we ensure that every kilowatt produced directly supports our sustainability roadmap and the decarbonization of the APAC region. By expanding onsite solar capacity, we aren't just reducing our carbon footprint; we are supporting resilient, clean energy infrastructure that allows
Iron Mountain to lead by example.

Supporting grid resilience
24/7 Carbon-Free Energy Data Centers
Conventional clean power solutions are designed to match a buyer's load annually. This approach does not account for whether clean power is available when clients use electricity, and as a result, doesn't help decarbonize the grid.
Iron Mountain's Data Center division became a founding signatory to the UN Compact on 24/7 Carbon-Free Energy, committing to seeking hour-by-hour matching of our site consumption with local carbon-free energy (CFE) by 2040. This approach not only supports the decarbonization of the grid, but allows us to offer the Green Power Pass product to customers. They can then report-at any Iron Mountain Data Center-the power they consume as clean power in their public reporting, making Iron Mountain an important part of their decarbonization roadmaps and commitments.
The tools used to monitor our progress toward our 24/7 CFE commitment of our data centers is also creating valuable insights for other facilities. We currently have over 201 locations globally, including over 137 locations in the United States, with the ability to track and match clean energy usage on an hourly basis.
Battery storage
Iron Mountain's data center division designed an innovative grid-enhancing Battery Energy Storage Systems (BESS) that delivered up to 100 megawatt (MW) of grid support across our Virginia campuses, the largest data center market in the world. BESS played a crucial role in stabilizing electricity grids and facilitating the integration of clean energy. While still at the concept stage, this R&D has the potential to significantly enhance the sustainability and resilience of the local grids we operate within. We are also developing a 12 MW battery storage solution at our New Jersey facility, scheduled for deployment in 2027.

Clean energy procurement
Our portfolio of clean energy solutions includes onsite generation, direct-to-supplier energy contracting, and virtual power purchase agreements for wind, solar, and hydropower.
In 2025, 93% of our global electricity consumption was covered by clean energy sources.
As of 2025, there were 65 facilities with onsite solar arrays in our global real estate portfolio, representing a cumulative system size of more than
24.6 MW.
Greener fleet
We have a comprehensive approach to reducing emissions from our fleet, including fleet electrification, the use of biofuels, dynamic routing that improves efficiency, and eco-friendly driving practices.
We now have 335 electric vehicles in service, or on order, across 31 countries.
Over the last two years we have been testing a fully-electric mobile shred unit as well as hybrid mobile shred units, in order to reduce emissions and noise from idling while servicing onsite shredding customers.
Water conservation and management
Remote monitoring of our irrigation systems allows us to customize irrigation schedules, taking into account weather, climate, soil, and plant types to fit each site's needs.
We have completed our evaluation and site implementation for our irrigation management program. As a result of the program, we have installed smart irrigation controls at 25 sites, which is estimated to save 12.6 million gallons of water annually. These prevent over watering, provide utility savings, and identify leaks and other potential issues early, minimizing impact.
The Iron Mountain Data Center team continued to align all new facility designs with the Climate-Neutral Data Centre Pact targets for Power Usage Effectiveness (PUE) and Water Usage Effectiveness (WUE). WUE overall improved from 1.81 to 0.996 globally from 2017 to 2024.
Waste reduction
Our strategy for waste management maximizes diversion and the reach of our recycling programs. We completed an analysis to identify top waste sources and opportunities for circular solutions.
Facility consolidations can generate one-time waste, potentially lowering our landfill diversion rates. In 2025, we recycled 32,300 tons of metal racking.
We recycled 515,375 pounds of secure shredding toters at the end of their useful life into reusable plastic pallets for our operations and resold or scrapped 460,300 pounds of powered industrial transport equipment from our facilities.
We partnered with Habitat for Humanity to donate more than 16,930 pounds of repurposed materials. We also provided the Salvation Army Disaster Relief Center with containers that were no longer in use, so they could become tornado relief kits, recycling more than 2,900 pounds of plastics.
