NASDAQ: OPI

Chapter 11 Bankruptcy Proceedings

On October 30, 2025, or the Petition Date, OPI and certain of its subsidiaries, or the Debtors, voluntarily commenced cases, or the Chapter 11 Cases, under chapter 11 of title 11, or Chapter 11, of the United States Code, or the Bankruptcy Code, in the United States Bankruptcy Court for the Southern District of Texas, Houston Division, or the Bankruptcy Court. In connection with the filing of the Chapter 11 Cases, OPI entered into a Restructuring Support Agreement, or the RSA, with certain holders of our 9.00% senior secured notes due September 2029, or the September 2029 Notes, to implement a court-supervised financial restructuring pursuant to the transactions contemplated in the RSA. In connection with the Chapter 11 Cases, certain holders of the September 2029 Notes provided OPI with a $125.0 million debtor-in-possession financing, or the DIP Facility, which was approved by the Bankruptcy Court on a final basis on February 4, 2026. For more information regarding the DIP Facility, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources” included in Part II, Item 7 of this Annual Report on Form 10-K and Note 9 to the Notes to Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10-K.

The Debtors continue to operate their businesses as debtors-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. As debtors-in-possession, the Debtors are authorized to pay all debts and honor all obligations arising in the ordinary course of our business after the Petition Date. However, generally, the Debtors may not pay third-party claims or creditors on account of obligations arising before the Petition Date or engage in transactions outside the ordinary course of business without prior approval of the Bankruptcy Court.

While the commencement of the Chapter 11 Cases constituted an event of default under certain of our debt agreements, enforcement of any remedies in respect of which is automatically stayed during the pendency of the Chapter 11 Cases. There are a number of risks and uncertainties associated with our bankruptcy proceedings, including, among others, that our prearranged plan of reorganization may not become effective.

On April 21, 2026, the Debtors filed the Fourth Amended Joint Chapter 11 Plan of Reorganization of Office Properties Income Trust and Its Debtor Affiliates, or the Plan. On April 22, 2026, the Bankruptcy Court entered the Order Confirming Fourth Amended Joint Chapter 11 Plan of Reorganization of Office Properties Income Trust and Its Debtor Affiliates confirming the Plan. After the satisfaction or waiver of the conditions precedent to the effectiveness of the Plan, the Debtors intend to effect the transactions contemplated by the Plan and emerge from Chapter 11 protection. There are a number of risks and uncertainties associated with our bankruptcy proceedings, including, among others, that the Plan may not become effective.

The Plan generally contemplates, among other things, that the following transactions and creditor treatment will be implemented:

•Holders of the September 2029 Notes will convert their debt into (i) $300 million in newly issued 10.000% senior secured notes due 2031, or the Secured Exit Notes, and (ii) up to $120 million of Secured Exit Notes and $98 million in newly issued shares of the reorganized common equity (subject to dilution pursuant to the Plan), or the Recovery

Pool; certain holders of the September 2029 Notes will be able to elect any combination of Secured Exit Notes and reorganized common equity up to their pro rata portion of the Recovery Pool, while the non-electing holders will receive their fixed pro rata portion of the Recovery Pool;

•Holders of our 3.25% Senior Secured Notes due 2027, will convert their debt into $385 million in newly issued 8.375% senior secured notes due 2029, or the New 2029 Secured Notes, to be issued by a wholly owned subsidiary of OPI;

•Holders of our 8.00% senior priority guaranteed unsecured notes due 2030, or the 2030 Notes, will receive 100% of their claims in newly issued shares of the reorganized common equity (subject to dilution pursuant to the Plan);

•Our existing secured revolving credit facility and term loan will be amended and restated;

•Our 9.00% Senior Secured Notes due March 2029, or the March 2029 Notes, will be reinstated and rendered unimpaired;

•Our mortgage notes will be unimpaired;

•Holders of DIP Facility claims, or DIP Claims, will receive (x) newly issued shares of the reorganized common equity (subject to dilution pursuant to the Plan) at a discount to Plan value of 37%; (y) in respect of the upfront fee under the DIP Facility, reorganized common equity (subject to dilution pursuant to the Plan) to be issued at a discount to Plan value of 37%, and (z) in respect of the anchor capital commitment fee and the exit fee under the DIP Facility, reorganized common equity (subject to dilution pursuant to the Plan) to be issued at Plan value;

•Holders of our other series of unsecured notes and certain unsecured deficiency claims will be treated as follows:

▪Holders of our other series of unsecured notes will receive their pro rata share of 6.3% of newly issued shares of the reorganized common equity (subject to dilution pursuant to the Plan), new warrants and the opportunity to participate in an equity rights offering in the aggregate amount of $35 million;

▪Holders of unsecured deficiency claims relating to the September 2029 Notes will receive their pro rata share of 5.3% of newly issued shares of the reorganized common equity (subject to dilution pursuant to the Plan);

•Allowed administrative claims, priority tax claims, other secured claims, trade and vendor claims and other priority claims will be paid in full in cash or receive such other treatment reinstating such claims or rendering such claims unimpaired;

•Other general unsecured claims that are allowed for $25,000 or less will be paid in full in cash and other general unsecured claims that are allowed for more than $25,000 may receive $25,000 in cash; and

•Holders of our common shares prior to the effective date of the Plan will not receive any distribution and such common shares will be cancelled, released and discharged on the effective date of the Plan.

The Plan also contemplates a new business management agreement and new property management agreements with The RMR Group LLC, or RMR, which agreements would take effect upon effectiveness of the Plan. The initial term of the new management agreements will be five years, with the annual fee under the business management agreement set at $14 million per year for the first two years and the fees under our property management agreements being consistent with the fees under the existing property management agreement. In addition to the management fees, the Plan contemplates that we will issue to RMR, on the effective date of the Plan, 2% of the reorganized common equity, and, following the effective date of the Plan, we may issue up to an additional 8% of the reorganized common equity based on the satisfaction of certain financial tests. Our current management agreements with RMR will remain in effect during the pendency of the Chapter 11 Cases, and RMR will continue to manage our business in the ordinary course. See Note 6 to the Notes to Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10-K for more information regarding our existing management agreements with RMR.

As discussed above, the Plan contemplates a new capital structure for the reorganized company, which reduces the outstanding debt of the reorganized company by approximately $700 million. The Plan has not yet become effective as of the date of filing of this Annual Report on Form 10-K. Effectiveness of the Plan is subject to a number of conditions precedent. There can be no assurance that all conditions to the effectiveness of the Plan will be satisfied or waived, or that the Plan will become effective on the timeline currently contemplated, or at all. Accordingly, the ultimate business plan for the reorganized

company is still uncertain, and the discussion of our investment and financing policies included below are subject to inherent risks and potential change.

Nasdaq Delisting

On September 25, 2025, The Nasdaq Stock Market LLC, or Nasdaq, notified us that our common shares were subject to delisting. We did not appeal Nasdaq’s determination, and our common shares were delisted from Nasdaq effective October 6, 2025.

Our Business Strategy

Our business plan is to focus on owning and leasing high-quality office and mixed-use properties in select, growth-oriented U.S. markets. We seek to diversify our revenue base across geographies with ownership in central business district, urban infill and suburban locations. Our approach emphasizes properties, markets or locations with high barriers to entry, qualities and characteristics to attract and retain talent and investment toward sustainability efforts.

Our internal growth strategy is to increase the rents and corresponding cash flows we receive from our current properties and to increase occupancy by leasing vacant space. To achieve these increases, we may invest in our properties through improvements requested by existing tenants or induce lease renewals or new tenant leases when our current leases expire or through development, redevelopment or repositioning activities. As our lease expirations approach, we will attempt to evaluate the highest and best use for a property and focus on proactive asset management to renew our leases with existing tenants or to enter leases with new tenants to enhance long-term cash flow growth and asset values. Our ability to renew leases with our existing tenants or to enter new leases with new tenants and the rents we are able to charge will depend in large part upon market conditions, which are beyond our control. We believe that if a property previously occupied by a single or majority tenant becomes vacant, it may be capital and time intensive to restabilize, redevelop or reposition depending on various factors including market conditions.

Our external growth strategy is defined by our acquisition, disposition and financing policies as described below. Our investment, financing and disposition policies and business strategies are established by our Board of Trustees and may be changed by our Board of Trustees at any time without shareholder approval.

Commercial Real Estate and Capital Markets

Certain shifts in office space utilization, including increased remote work arrangements and tenants consolidating their real estate footprint, as well as, declining rents and increasing costs to re-lease space when new tenants can be identified continue to impact the market. The demand for office space continues to face headwinds and the duration and ultimate impact of current trends on the demands for office space at our properties remains uncertain and subject to change. Accordingly, we do not yet know what the full extent of the impacts will be on our or our tenants’ businesses and operations nor the long-term outlook for leasing our properties. Higher interest rates, inflationary pressures, government policies (including the potential reduction of U.S. federal office leases), geopolitical events, an economic recession or disruptions in the financial markets could adversely affect our and our tenants’ financial condition and the ability or willingness of our tenants to renew our leases or pay rent to us. Deteriorating office fundamentals, high interest rates and market sentiment towards the office sector may restrict our access to, and increase our cost of, capital and may cause the values of our properties and our securities to decline.

Our Investment Policies

Our primary investment objectives include increasing cash flows from operations from stable and diverse sources. Although our business plan does not currently contemplate the acquisition of additional properties, we may acquire additional properties in the future to enhance our overall portfolio composition and produce greater returns than those properties or portfolios we may sell. To achieve these objectives, we may seek to: (a) invest in institutional quality properties with an emphasis on high credit quality tenants; (b) use proceeds from asset sales to manage leverage levels; (c) when market conditions permit, refinance debt with long term debt or additional equity; and (d) pursue capital allocation strategies so that our cash flow from operations comes from a diversified portfolio of properties, geographies, industries and tenants.

Acquisition Policies. We intend to focus future investments primarily in U.S. office, mixed-use or similar type properties in markets we believe have strong economic fundamentals to support growth, including (1) properties leased to a single or majority tenant that are strategic to that tenant and which may include built-to-suit, specialty use or corporate or regional headquarters and properties where the tenant has invested meaningful capital, with a minimum remaining lease term of at least seven years and (2) properties with specialty uses or those deemed to be mission critical to a user.

In implementing an acquisition strategy, we would consider a range of factors relating to proposed property purchases, including:

•our cost of capital compared to the projected returns we may realize by owning the property;

•the historic and projected rents received and likely to be received from the property;

•the historic and expected operating expenses, incurred and expected to be incurred at the property;

•the remaining term of the lease(s) at the property and other lease terms;

•the experience and credit quality of the property’s tenant(s);

•the pricing of comparable properties as evidenced by recent arm’s length market sales;

•the price at which the property may be acquired or redeveloped;

•the existence of alternative sources, uses or needs for our capital, including our debt leverage;

•the ongoing and expected capital requirements for the property;

•the return on the properties being sold to finance acquisitions or property developments, redevelopments or repositionings compared to the projected returns we may realize by owning the property we would acquire or develop, redevelop or reposition;

•the current or potential market position of the property;

•the type of property (e.g., single tenant, multi-tenant, specialty use, etc.);

•the likelihood of the tenant(s) renewing at lease expiration;

•the market location of the property and our assessment of rent growth for that market;

•the industry(ies) in which the tenant(s) operate;

•the strategic fit of the property with the rest of our properties and how it may strategically improve key attributes of our portfolio, including alignment with our Environmental, Social and Governance, or ESG, principles;

•the current and expected future space utilization at the property by its tenant(s);

•the use and size of the property;

•the construction quality, physical condition, age and design of the property;

•the growth, tax and regulatory environments of the market in which the property is located;

•the occupancy and demand for similar properties in the same or nearby markets; and

•the estimated replacement cost of the property.

Other Acquisitions. We prefer wholly owned investments in fee interests. However, we may consider investing in leaseholds, joint ventures, mortgages and other real estate interests. As of December 31, 2025, we owned a 51% interest in an unconsolidated joint venture. In the future, we may invest in or enter into additional real estate joint ventures if we conclude that by doing so we may benefit from the participation of co-venturers, or that our opportunity to participate in the investment is contingent on the use of a joint venture structure or that pre-existing joint venture arrangements may be part of an acquisition or development we wish to pursue. We may invest in participating, convertible or other types of mortgages if we conclude that by doing so, we may benefit from the cash flow or appreciation in the value of a property which is not available for purchase.

We have in the past considered, and may in the future consider, the possibility of entering into mergers or strategic combinations with other companies. The principal goals of any such transaction will be to increase our cash flow from operations and to further diversify our revenue sources.

We have no policies which specifically limit the percentage of our assets that may be invested in any individual property, in any one type of property, in properties managed by or leased to any one entity, in properties managed by or leased to any affiliated group of entities or in securities of one or more other persons.

Our Board of Trustees may change our acquisition policies without a vote of, or notice to, our shareholders.

Disposition Policies. We expect to sell properties, or sell an interest in properties through joint venture arrangements, from time to time, in order to manage leverage levels or to recycle capital into properties that we believe have better long term earnings potential or that we believe will help diversify our revenue base, improve the average age of our properties, lengthen the weighted average term of our leases, reduce our ongoing capital requirements and/or increase our distributions to shareholders. We make disposition decisions based on a number of factors including, but not limited to, the following:

•the estimated sales price or value we may receive by selling the property;

•the capital required to maintain the property;

•our expectation regarding tenant lease renewals or the likelihood of finding (a) replacement tenant(s) if the property has significant vacancies or is likely to become substantially vacant;

•our evaluation of future rent for the property relative to leasing costs;

•the strategic fit of the property or investment with the rest of our portfolio;

•the remaining length of the current lease(s) and its (their) other terms;

•the potential costs associated with finding (a) replacement tenant(s), including tenant improvements, leasing commissions and concessions, the cost to operate the property while vacant and building improvement capital, as compared to our projected returns from future rents;

•the occupancy of the property;

•the future expected space utilization of the tenant(s) and the potential impact that may have on occupancy at the property;

•whether the property’s tenant(s) is (are) current on its (their) lease obligation(s);

•our evaluation of the property’s tenant(s) ability to pay its (their) contractual rents;

•the highest and best use of the property;

•our intended use of the proceeds we may realize from the sale of a property;

•the tax implications to us and our shareholders of any proposed dispositions;

•our financial position and needs from time to time; and

•the existence of alternative sources, uses or needs for capital, including our debt leverage.

Our Board of Trustees may change our disposition policies without a vote of, or notice to, our shareholders.

Our Financing Policies

To qualify for taxation as a REIT under the United States Internal Revenue Code of 1986, as amended, or the IRC, we must distribute at least 90% of our annual REIT taxable income (excluding net capital gains). Accordingly, we generally will not be able to retain sufficient cash to fund our operations, repay our debts, invest in our properties and fund acquisitions and development, redevelopment and repositioning efforts. We generally expect to repay our debts, invest in our properties and fund acquisitions and development, redevelopment and repositioning efforts with proceeds from debt or equity we may issue, proceeds from our asset sales or retained cash from operations that may exceed any distributions we may pay. Our ability to issue additional indebtedness, dispose of assets or access capital markets is substantially limited as a result of the Chapter 11

Cases and will require Bankruptcy Court approval in most instances. Accordingly, our liquidity primarily depends on cash generated from operating activities and borrowings under the DIP Facility.

For more information regarding our financing sources and activities, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in Part II, Item 7 and Note 9 to the Notes to Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10-K.

Our Board of Trustees may change our financing policies at any time without a vote of, or notice to, our shareholders.

Other Information

Employees. We have no employees. Services which would otherwise be provided to us by employees are provided by RMR and by our Managing Trustees and officers. As of December 31, 2025, RMR had nearly 900 full time employees in its headquarters and regional offices located throughout the United States.

Our Manager. The RMR Group Inc., or RMR Inc., is a holding company and substantially all of its business is conducted by its majority owned subsidiary, RMR. The Chair of our Board of Trustees and one of our Managing Trustees, Adam D. Portnoy, is the sole trustee, an officer and the controlling shareholder of ABP Trust, which is the controlling shareholder of RMR Inc., the chair of the board of directors, a managing director and the president and chief executive officer of RMR Inc. and an officer and employee of RMR. Yael Duffy, our other Managing Trustee and our President and Chief Executive Officer, is also an executive officer of RMR Inc. and as an officer and employee of RMR, and each of our other officers is also an officer and employee of RMR. Our day to day operations are conducted by RMR. RMR originates and presents investment and divestment opportunities to our Board of Trustees and provides management and administrative services to us. RMR has a principal place of business at Two Newton Place, 255 Washington Street, Suite 300, Newton, Massachusetts 02458-1634, and its telephone number is (617) 796-8390.

RMR is an alternative asset management company that is focused on both commercial and residential real estate and related businesses. RMR or its subsidiaries also act as a manager to other publicly traded real estate companies, privately held real estate funds and real estate related operating businesses. As of May 18, 2026, the executive officers of RMR are: Adam Portnoy, president and chief executive officer; Christopher J. Bilotto, executive vice president; Matthew C. Brown, executive vice president, chief financial officer and treasurer; Yael Duffy, executive vice president; Lindsey Getz, executive vice president, general counsel and secretary; Matthew P.

Donley, is a senior vice president of RMR. Ms. Duffy, Mr. Donley and other officers of RMR also serve as officers of other companies to which RMR or its subsidiaries provide management services.

Corporate Sustainability. Our manager, RMR, periodically publishes its Sustainability Report, which summarizes the environmental, social and governance initiatives employed by RMR and its client companies, including us. RMR’s Sustainability Report may be accessed on the RMR Inc. website at www.rmrgroup.com/corporate-sustainability/default.aspx. The information on or accessible through RMR Inc.’s website is not incorporated by reference into this Annual Report on Form 10-K.

We believe corporate sustainability is a strategic part of our focus on operational practices, enhancing our competitive position, development and redevelopment efforts and economic performance. Our sustainability practices, which align with those of our manager, RMR — minimizing our impact on the environment, embracing the communities where we operate and attracting top professionals — are critical elements supporting our long-term success.

We recognize our responsibility to minimize the impact of our business on the environment and seek to preserve natural resources and maximize efficiencies in order to reduce the impact our properties have on the planet. Our environmental sustainability strategies and best practices help to mitigate our properties’ environmental footprint, optimize operational efficiency and enhance our competitiveness in the marketplace. Our sustainability and community engagement strategies focus on a complementary set of objectives, including the following:

•Responsible Investment. We seek to invest capital in our properties that both improves environmental performance and enhances asset value. During the property acquisition due diligence and annual budgeting processes, RMR assesses, among other things, environmental sustainability opportunities and physical and policy driven climate related risks.

•Environmental Stewardship. We seek to improve the environmental footprint of our properties, including by reducing carbon emissions, energy consumption and water usage, especially when doing so may reduce operating

costs and exposure to policies that call for a carbon tax or other emissions-based penalties and enhance the properties’ competitive position. Our existing business practices are intended to align with the Task Force on Climate-Related Financial Disclosures framework across both the physical and transition risks and opportunities. With respect to our development and redevelopment activities, RMR considers how to best incorporate sustainability goals as part of the overall goal of any development or redevelopment project at our properties.

We and our manager, RMR, drive value, manage risk and benchmark the performance of our properties by effectively capturing and managing data and by achieving environmental and energy efficiency certifications and designations. RMR’s real-time energy monitoring program, or RTM, facilitates advanced data analytics to detect faults and inefficiencies in equipment operations while enhancing building system control in a cost-effective and scalable way. RMR’s RTM program captures 41 of our properties totaling approximately 71% of our annual electricity spend and generating approximately $2.1 million in annual savings.

Furthermore, properties that reach specified levels of sustainability and energy efficiency may receive potential environmental designations and certifications, such as Leadership in Energy and Environmental Design, or LEED®, designations and/or “ENERGY STAR” certifications. LEED designations are administered by the U.S. Green Building Council. The ENERGY STAR program is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy which is focused on promoting energy efficient products and properties. The U.S. government’s “green lease” policies permit government tenants to require LEED® designation in selecting new premises or renewing leases at existing premises and the General Services Administration gives preference to properties for lease that have received an ENERGY STAR certification. As of December 31, 2025, our LEED designations and ENERGY STAR certifications were as follows:

•LEED: 47 properties containing 6.7 million rentable square feet (43.5% and 45.0% of our total properties and total rentable square feet, respectively).

•ENERGY STAR: 33 properties containing 5.3 million rentable square feet (33.0% and 37.6% of our eligible properties and eligible rentable square feet, respectively).

In 2024, we were recognized as an Energy Star® Partner of the Year for the seventh consecutive year and a Sustained Excellence honoree for the fifth consecutive year.

•Investments in Human Capital. We have no employees. We rely on our manager, RMR, to hire, train, and develop a workforce that meets the needs of our business, contributes positively to our society and helps reduce our impact on the natural environment.

•Corporate Citizenship. We seek to be a responsible corporate citizen and to strengthen the communities in which we own properties. Our manager, RMR, regularly encourages its employees to engage in a variety of charitable and community programs, including participation in a company-wide service day and a charitable giving matching program.

•Diversity & Inclusion. We value a diversity of backgrounds, experience and perspectives. As of December 31, 2025, our Board of Trustees was comprised of nine Trustees, of which seven were independent trustees, four, or approximately 44%, were female and one, or approximately 11%, was a member of under-represented communities. RMR is an equal opportunity employer, with all qualified applicants receiving consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability or protected veteran status.

For more information, see “Risk Factors—Risks Related to Our Business—Sustainability initiatives, requirements and market expectations may impose additional costs and expose us to new risks.” included in Part I, Item 1A of this Annual Report on Form 10-K.

Competition. Investing in and operating real estate properties is a highly competitive business. We compete against publicly traded and private REITs, numerous financial institutions, individuals and public and private companies, including entities funded by both domestic and foreign capital, who are actively engaged in this business. Some of our competitors may have greater financial and other resources, or lower costs of capital than us. Also, we compete for investments based on a number of factors, including purchase prices, closing terms, underwriting criteria and our and RMR’s reputations. Our ability to successfully compete is also materially impacted by the availability and cost of capital to us. We do not believe we have a dominant position in any of the geographic markets in which we operate, but some of our competitors are dominant in selected markets. We believe the experience and abilities of our management and our manager, the quality of our properties, the

diversity and credit qualities of our tenants, and the structure of our leases may afford us some competitive advantages and allow us to operate our business successfully despite the competitive nature of our business. For additional information about competition and other risks associated with our business, see “Risk Factors” included in Part I, Item 1A of this Annual Report on Form 10-K.

Leases. We have leases with government entities, including the U.S. government, state governments and other government tenants as well as non-government tenants. Some of our leases allow tenants to vacate the leased premises before the stated expirations of their leases with little or no liability, or with penalty, by exercising early termination rights. For additional information about our tenants’ rights to terminate leases early, see “Risk Factors—Risks Related to Our Business—Some tenants have the right to terminate their leases prior to their lease expiration date” included in Part I, Item 1A and “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Overview—Property Operations” included in Part II, Item 7 of this Annual Report on Form 10-K.

Other Matters. Legislative and regulatory developments may occur at the federal, state and local levels that have direct or indirect impact on the ownership, leasing and operation of our properties. We may need to make expenditures, to the extent these costs are not paid by our tenants, due to changes in government regulations, or the application of such regulations to our properties, including the Americans with Disabilities Act, fire and safety regulations, building codes, land use regulations or environmental regulations on containment, abatement or removal.

Segment Information. As of December 31, 2025, we had one operating segment: direct ownership of real estate properties. For more information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in Part II, Item 7 and our Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10-K.
