4RETURN TO TABLE OF CONTENTS Q1 2025 OFFICE PROPERTIES INCOME TRUST ANNOUNCES FIRST QUARTER 2025 FINANCIAL RESULTS “OPI's results this quarter reflect the ongoing operational challenges in our portfolio, from tenant non-renewals, continued headwinds in our key markets and increased debt service costs from our re-financing activities. We remain focused on capitalizing on leasing opportunities and tenant retention. During the first quarter, we completed 223,000 square feet of new and renewal leasing at a 13.5% roll-up in rent and a weighted average lease term of over 10 years, ending the quarter with same property portfolio occupancy of 85.4%. Additionally, we completed the sale of three properties, consisting of 249,000 square feet, for $26.9 million, and have agreements in place to sell three more properties, consisting of 376,000 square feet, for a total of $28.9 million. We also continue to work with our financial advisors to evaluate strategies to manage our upcoming debt maturities within the constraints of our limited liquidity and debt covenants."

23RETURN TO TABLE OF CONTENTS Q1 2025 Management: OPI is managed by The RMR Group (Nasdaq: RMR). RMR is an alternative asset management company that is focused on commercial real estate and related businesses. RMR primarily provides management services to publicly traded real estate companies, privately held real estate funds and real estate related operating businesses. As of March 31, 2025, RMR had approximately $40 billion of real estate assets under management and the combined RMR managed companies had more than $5 billion of annual revenues, approximately 1,900 properties and over 18,000 employees. OPI believes that being managed by RMR is a competitive advantage for OPI because of RMR’s depth of management and experience in the real estate industry. OPI also believes RMR provides management services to it at costs that are lower than OPI would have to pay for similar quality services if OPI were self managed.

36RETURN TO TABLE OF CONTENTS Q1 2025 Non-GAAP Financial Measures OPI presents certain “non-GAAP financial measures” within the meaning of the applicable rules of the Securities and Exchange Commission, or the SEC, including NOI, Cash Basis NOI, Same Property NOI, Same Property Cash Basis NOI, EBITDA, EBITDAre, Adjusted EBITDAre, FFO, Normalized FFO and CAD. These measures do not represent cash generated by operating activities in accordance with GAAP and should not be considered alternatives to net income (loss) as indicators of OPI's operating performance or as measures of OPI's liquidity. These measures should be considered in conjunction with net income (loss) as presented in OPI's consolidated statements of income (loss). OPI considers these non-GAAP measures to be appropriate supplemental measures of operating performance for a REIT, along with net income (loss). OPI believes these measures provide useful information to investors because by excluding the effects of certain historical amounts, such as depreciation and amortization expense, they may facilitate a comparison of OPI's operating performance between periods and with other REITs and, in the case of NOI, Cash Basis NOI, Same Property NOI and Same Property Cash Basis NOI reflecting only those income and expense items that are generated and incurred at the property level may help both investors and management to understand the operations of OPI's properties. NOI and Cash Basis NOI The calculations of net operating income, or NOI, and Cash Basis NOI exclude certain components of net income (loss) in order to provide results that are more closely related to OPI's property level results of operations. OPI calculates NOI and Cash Basis NOI as shown on page 25 and Same Property NOI and Same Property Cash Basis NOI as shown on page 26. OPI defines NOI as income from OPI's real estate less OPI's property operating expenses. NOI excludes amortization of capitalized tenant improvement costs and leasing commissions that OPI records as depreciation and amortization expense. OPI defines Cash Basis NOI as NOI excluding non-cash straight line rent adjustments, lease value amortization, lease termination fees, if any, and non-cash amortization included in other operating expenses. OPI calculates Same Property NOI and Same Property Cash Basis NOI in the same manner that OPI calculates the corresponding NOI and Cash Basis NOI amounts, except that OPI only includes same properties in calculating Same Property NOI and Same Property Cash Basis NOI. OPI uses NOI, Cash Basis NOI, Same Property NOI and Same Property Cash Basis NOI to evaluate individual and company-wide property level performance. Other real estate companies and REITs may calculate NOI, Cash Basis NOI, Same Property NOI and Same Property Cash Basis NOI differently than OPI does. EBITDA, EBITDAre and Adjusted EBITDAre OPI calculates earnings before interest, taxes, depreciation and amortization, or EBITDA, EBITDA for real estate, or EBITDAre, and Adjusted EBITDAre as shown on page 28. EBITDAre is calculated on the basis defined by The National Association of Real Estate Investment Trusts, or Nareit, which is EBITDA, excluding gains and losses on the sale of real estate, loss on impairment of real estate assets and adjustments to reflect OPI's share of EBITDAre of its unconsolidated joint venture. In calculating Adjusted EBITDAre, OPI adjusts for the items shown on page 28 and includes business management incentive fees, if any, only in the fourth quarter versus the quarter when they are recognized as expense in accordance with GAAP due to their quarterly volatility not necessarily being indicative of OPI's core operating performance and the uncertainty as to whether any such business management incentive fees will be payable when all contingencies for determining such fees are known at the end of the calendar year. Other real estate companies and REITs may calculate EBITDA, EBITDAre and Adjusted EBITDAre differently than OPI does. FFO and Normalized FFO OPI calculates funds from operations, or FFO, and Normalized FFO as shown on page 29. FFO is calculated on the basis defined by Nareit, which is net income (loss), calculated in accordance with GAAP, plus real estate depreciation and amortization of consolidated properties and OPI's proportionate share of the real estate depreciation and amortization of unconsolidated joint venture properties, but excluding impairment charges on real estate assets and any gain or loss on sale of real estate, as well as certain other adjustments currently not applicable to us. In calculating Normalized FFO, OPI adjusts for the other items shown on page 29 and includes business management incentive fees, if any, only in the fourth quarter versus the quarter when they are recognized as an expense in accordance with GAAP due to their quarterly volatility not necessarily being indicative of OPI's core operating performance and the uncertainty as to whether any such business management incentive fees will be payable when all contingencies for determining such fees are known at the end of the calendar year. FFO and Normalized FFO are among the factors considered by OPI's Board of Trustees when determining the amount of distributions to OPI's shareholders. Other factors include, but are not limited to, requirements to maintain OPI's qualification for taxation as a REIT, limitations in OPI's credit agreement and public debt covenants, the availability to OPI of debt and equity capital, OPI's expectation of its future capital requirements and operating performance and OPI's expected needs for and availability of cash to pay its obligations. Other real estate companies and REITs may calculate FFO and Normalized FFO differently than OPI does. Cash Available for Distribution OPI calculates cash available for distribution, or CAD, as shown on page 29. OPI defines CAD as Normalized FFO minus recurring real estate related capital expenditures and adjusted for other non-cash and non- recurring items and certain amounts excluded from Normalized FFO but settled in cash. CAD is among the factors considered by OPI's Board of Trustees when determining the amount of distributions to OPI's shareholders. Other real estate companies and REITs may calculate CAD differently than OPI does. Non-GAAP Financial Measures and Certain Definitions
