**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS** 

**(dollars in thousands, except per share data)**

**(unaudited)**

**Note 1. Basis of Presentation**

The accompanying condensed consolidated financial statements of Office Properties Income Trust and its subsidiaries, or OPI, we, us or our, are unaudited. Certain information and disclosures required by U.S. generally accepted accounting principles, or GAAP, for complete financial statements have been condensed or omitted. We believe the disclosures made are adequate to make the information presented not misleading. However, the accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes contained in our Annual Report on Form 10-K for the year ended December 31, 2025, or our 2025 Annual Report. In the opinion of management, all adjustments, consisting of normal recurring accruals considered necessary for a fair statement of results for the interim period have been included. All intercompany transactions and balances with or among our consolidated subsidiaries have been eliminated. Our operating results for interim periods are not necessarily indicative of the results that may be expected for the full year.

The preparation of these financial statements in conformity with GAAP requires us to make estimates and assumptions that affect reported amounts. Actual results could differ from those estimates. Significant estimates in the condensed consolidated financial statements include purchase price allocations, useful lives of fixed assets and assessment of impairment of real estate and the related intangibles.

*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 $125,000 debtor-in-possession financing, or the DIP Facility, which was approved by the Bankruptcy Court on a final basis on February 4, 2026. See Note 7 for more information regarding the DIP Facility.

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Holders of the September 2029 Notes will convert their debt into (i) $300,000 in newly issued 10.000% senior secured notes due 2031, or the Secured Exit Notes, and (ii) up to $120,000 of Secured Exit Notes and $98,000 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Holders of our 3.25% Senior Secured Notes due 2027 will convert their debt into $385,000 in newly issued 8.375% senior secured notes due 2029, to be issued by a wholly owned subsidiary of OPI;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our 9.00% Senior Secured Notes due March 2029 will be reinstated and rendered unimpaired;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Any claims under our mortgage notes will be unimpaired;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Holders of DIP Facility 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;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ 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 $35,000;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ 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);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 $14,000 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 9 for more information regarding our existing management agreements with RMR.

**(DEBTOR-IN-POSSESSION)**

**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)**

**(dollars in thousands, except per share data)**

**(unaudited)**

Under the Bankruptcy Code, we may assume, modify, assign or reject certain executory contracts and unexpired leases, including, without limitation, leases of real property and equipment, subject to the approval of the Bankruptcy Court and to certain other conditions. Generally, the rejection of an executory contract or unexpired lease is treated as a pre-petition breach of such executory contract or unexpired lease and, subject to certain exceptions, relieves us from performing the future obligations under such executory contract or unexpired lease but entitles the contract counterparty or lessor to a pre-petition general unsecured claim for damages caused by such deemed breach. Generally, the assumption of an executory contract or unexpired lease requires us to cure existing monetary defaults under such executory contract or unexpired lease and provide adequate assurance of future performance. Accordingly, any description of an executory contract or unexpired lease in these financial statements including, where applicable, the express termination rights thereunder or a quantification of their obligations, must be read in conjunction with, and is qualified by, any overriding rejection rights we have under the Bankruptcy Code.

The Plan has not yet become effective as of the date of filing of this Quarterly Report on Form 10-Q. 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.

*Going Concern*

Substantial doubt about our ability to continue as a going concern exists due to (1) insufficient liquidity to satisfy our obligations as they come due, (2) limited alternatives available to us to obtain debt or equity financing, (3) inability to refinance our maturing debt, and (4) the resulting Chapter 11 Cases. Our ability to continue as a going concern is contingent upon, among other things, our ability to implement the Plan and generate sufficient liquidity following the reorganization to meet our obligations, restructured debt obligations and operating needs.

The transactions contemplated by the Plan are subject to certain conditions. Accordingly, no assurance can be given that the transactions described therein will be consummated. As a result, we have concluded that management's plans at this stage do not alleviate substantial doubt about our ability to continue as a going concern.

The accompanying unaudited condensed consolidated financial statements are prepared in accordance with GAAP applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business, and do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

*Bankruptcy Accounting*

Effective on the Petition Date, we applied Financial Accounting Standards Board Accounting Standards Codification Topic 852, *Reorganizations,* or ASC 852, which specifies the accounting and financial reporting requirements for entities reorganizing through Chapter 11 bankruptcy proceedings. These requirements include distinguishing transactions directly associated with the reorganization reported separately as reorganization items, net in the condensed consolidated statement of comprehensive income (loss) and the condensed consolidated balance sheet must distinguish certain liabilities subject to compromise, or LSTC. See Note 2 for more information.

Upon emergence from bankruptcy on the effective date of the Plan, we expect to qualify for fresh-start reporting. In order to qualify for fresh-start reporting (i) the holders of existing voting shares of OPI prior to its emergence must receive less than 50% of the outstanding voting shares of the reorganized company following its emergence from bankruptcy and (ii) the reorganization value of OPI's assets immediately prior to confirmation of the Plan must be less than the post-petition liabilities and allowed claims. Under the principles of fresh-start reporting, a new reporting entity, or the Successor, will be considered to have been created, and, as a result, the Successor will allocate the reorganization value of the Successor to its individual assets based on their estimated fair values.

**Note 2. Chapter 11 Cases**

*Liabilities Subject to Compromise.* As of March 31, 2026 and December 31, 2025, we reclassified certain LSTC in our condensed consolidated balance sheets. These liabilities are reported at the amounts expected to be allowed as claims by the Bankruptcy Court. The amounts are preliminary and may be subject to future adjustments depending on Bankruptcy Court actions, developments with respect to disputed claims, determinations of the secured status of certain claims, the values of any collateral securing such claims, rejection of executory contracts, continued reconciliation or other events. The following table presents LSTC as of March 31, 2026 and December 31, 2025:

---

| | | |
|:---|:---|:---|
| | **As of March 31, 2026** | **As of December 31, 2025** |
| Debt | $1519069 | $1519069 |
| Accrued interest | 42230 | 42230 |
| Accounts payable and other liabilities | 8108 | 16834 |
| &nbsp;&nbsp;Total liabilities subject to compromise | $1569407 | $1578133 |

---

The determination of how liabilities will ultimately be settled or treated cannot be made until the Plan becomes effective. Accordingly, we cannot determine the ultimate amount of such liabilities at this time.

*Contractual interest.* Effective as of the Petition Date, we ceased accruing interest expense on our unsecured debt instruments. As a result, we did not recognize $5,111 of aggregate contractual interest expense during the three months ended March 31, 2026 that would have otherwise been recorded under these instruments.

*Reorganization items, net.* Reorganization items, net represent amounts incurred after the Petition Date as a direct result of the Chapter 11 Cases and are comprised of bankruptcy-related professional fees and adjustments to reflect the carrying value of LSTC at their estimated allowed claim amounts. The following table presents reorganization items, net during the three months ended March 31, 2026:

|:---|:---|
| | **Three Months Ended March 31, 2026** |
| Professional fees | $57829 |

**Note 3. Per Common Share Amounts**

We calculate basic earnings per common share using the two class method. We calculate diluted earnings per common share using the more dilutive of the two class method or the treasury stock method. Unvested share awards and other potentially dilutive common shares, together with the related impact on earnings, are considered when calculating diluted earnings per common share. The calculation of basic and diluted earnings per common share is as follows (amounts in thousands, except per share data):

**Note 4. Real Estate Properties**

As of March 31, 2026, our 122 wholly owned properties contained approximately 17,113,000 rentable square feet, with an undepreciated carrying value of $3,681,681. We also had a noncontrolling ownership interest of 51% in an unconsolidated joint venture that owned two properties containing approximately 346,000 rentable square feet. We generally lease space at our properties on a gross lease, modified gross lease or net lease basis pursuant to fixed term contracts expiring between 2026 and 2044. Some of our leases generally require us to pay all or some property operating expenses and to provide all or most property management services. During the three months ended March 31, 2026, we entered into 13 leases for approximately 212,000 rentable square feet for a weighted (by rentable square feet) average lease term of 4.5 years, and we made commitments of $4,516 for leasing related costs. As of March 31, 2026, we had estimated unspent leasing related obligations of $54,390.

We regularly evaluate whether events or changes in circumstances have occurred that could indicate an impairment in the value of long lived assets. Impairment indicators may include declining tenant occupancy, lack of progress re-leasing vacant space, tenant bankruptcies, low long term prospects for improvement in property performance, weak or declining tenant profitability, cash flow or liquidity, our decision to dispose of an asset before the end of its estimated useful life and legislative, market or industry changes that could permanently reduce the value of a property. If there is an indication that the carrying value of an asset is not recoverable, we estimate the projected undiscounted cash flows to determine if an impairment loss should be recognized. The future net undiscounted cash flows are subjective and are based in part on assumptions regarding hold periods, market rents and terminal capitalization rates. We determine the amount of any impairment loss by comparing the historical carrying value to estimated fair value. We estimate fair value through an evaluation of recent financial performance and projected discounted cash flows using standard industry valuation techniques. In addition to consideration of impairment upon the events or changes in circumstances described above, we regularly evaluate the remaining useful lives of our long lived assets. If we change our estimate of the remaining useful lives, we allocate the carrying value of the affected assets over their revised remaining useful lives.

*Dispositions*

We did not sell any properties during the three months ended March 31, 2026. As of May 18, 2026, we had one property in Reston, VA containing approximately 275,000 rentable square feet under agreement to sell for a sales price of $18,125, excluding closing costs. This pending sale is subject to conditions; accordingly, we cannot be sure that we will complete this sale or that this sale will not be delayed or the pricing will not change.

*Unconsolidated Joint Venture*

As of March 31, 2026, we owned an interest in one joint venture that owned two properties. We accounted for this investment under the equity method of accounting.

As of March 31, 2026 and December 31, 2025, our investment in our unconsolidated joint venture is as follows:

As of March 31, 2026 and December 31, 2025, the mortgage debt of our unconsolidated joint venture is as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Joint Venture** | **Interest Rate** <sup>(1)</sup> | **Maturity Date** | **Principal Balance at March 31, 2026** <sup>(2)</sup> | **Principal Balance at December 31, 2025** <sup>(2)</sup> |
| Prosperity Metro Plaza | 4.09% | 12/1/2029 | $48877 | $49106 |

---

(1)Includes the effect of mark to market purchase accounting.

(2)Reflects the entire balance of the debt secured by the properties and is not adjusted to reflect the interest in the joint venture we did not own. None of the debt is recourse to us.

The filing of the Chapter 11 Cases constituted an event of default under the mortgage note secured by the properties owned by the Prosperity Metro Plaza joint venture. The Prosperity Metro Plaza joint venture remains current on debt service under this mortgage note and continues to own, operate and lease the collateral properties.

As of March 31, 2026, the unamortized basis difference of our joint venture of $638 was primarily attributable to the difference between the amount we paid to purchase our interest in the joint venture, including transaction costs, and the historical carrying value of the net assets of the joint venture. The difference is being amortized over the remaining useful life of the related property and the resulting amortization expense is included in equity in net losses of investees in our condensed consolidated statements of comprehensive income (loss).

**Note 5. Leases**

Our leases provide for base rent payments and, in addition, may include variable payments. Rental income from operating leases, including any payments derived by index or market-based indices, is recognized on a straight line basis over the lease term once we have determined that the collectability of substantially all of the lease payments is probable. Some of our leases have options to extend or terminate the lease exercisable at the option of our tenants, which are considered when determining the lease term. Allowances for bad debts are recognized as a direct reduction of rental income. In certain circumstances, some leases provide the tenant with the right to terminate if the legislature or other funding authority does not appropriate the funding necessary for the tenant to meet its lease obligations; we have determined the fixed non-cancelable lease term of these leases to be the full term of the lease because we believe the occurrence of early terminations to be a remote contingency based on both our historical experience and our assessments of the likelihood of lease cancellation on a separate lease basis.

We recorded rental income under our leases of $101,766 and $106,462 during the three months ended March 31, 2026 and 2025, respectively, including adjustments to increase rental income to record revenue on a straight line basis by $1,936 and $6,856 during the three months ended March 31, 2026 and 2025, respectively. Rents receivable included $153,461 and $151,525 of straight line rent receivables at March 31, 2026 and December 31, 2025, respectively.

**(unaudited)**

We do not include in our measurement of our lease receivables certain variable payments, including payments determined by changes in the index or market-based indices after the inception of the lease, certain tenant reimbursements and other income until the specific events that trigger the variable payments have occurred. Such payments totaled $19,377 and $19,854 for the three months ended March 31, 2026 and 2025, respectively, of which tenant reimbursements totaled $18,567 and $19,092, respectively.

**Note 6. Concentration** 

*Tenant and Credit Concentration* 

As of March 31, 2026 and 2025, the U.S. government and certain state and other government tenants combined were responsible for approximately 26.1% and 25.1%, respectively, of our annualized rental income. The U.S. government is our largest tenant by annualized rental income and represented approximately 17.5% and 16.8% of our annualized rental income as of March 31, 2026 and 2025, respectively. We define annualized rental income as the annualized contractual base rents from our tenants pursuant to our lease agreements as of the measurement date, plus straight line rent adjustments and estimated recurring expense reimbursements to be paid to us, and excluding lease value amortization.

*Geographic Concentration* 

As of March 31, 2026, our 122 wholly owned properties were located in 29 states and the District of Columbia. Properties located in Virginia, California, Georgia, Illinois and Texas were responsible for approximately 14.3%, 11.4%, 10.8%, 10.4% and 10.2% of our annualized rental income as of March 31, 2026, respectively.

**Note 7. Indebtedness**

*Credit Agreement, Senior Notes and Mortgage Notes*

Our principal debt obligations as of March 31, 2026 were: (1) $325,000 of outstanding borrowings under our $325,000 secured revolving credit facility; (2) $100,000 outstanding principal amount under our secured term loan; (3) $1,819,069 aggregate outstanding principal amount of senior notes; (4) $177,320 aggregate outstanding principal amount of mortgage notes; and (5) $86,913 outstanding principal amount under our secured debtor-in-possession term loan.

Our $325,000 secured revolving credit facility and $100,000 secured term loan are governed by a credit agreement, or our credit agreement, with a syndicate of institutional lenders. As collateral for all loans and other obligations under our credit agreement, certain of our subsidiaries pledged all of their respective equity interests in certain of our direct and indirect property owning subsidiaries, and our pledged subsidiaries provided first mortgage liens on 19 properties that had a gross book value of real estate assets of $1,035,771 as of March 31, 2026. The maturity date of our credit agreement is January 29, 2027. Our credit agreement contains a number of covenants, including covenants that require us to maintain certain financial ratios, restrict our ability to incur additional debt in excess of calculated amounts and, subject to limited exceptions, restrict our ability to increase our distribution rate above $0.01 per common share per quarter and enter into share repurchases. Availability of borrowings under our credit agreement is subject to ongoing minimum performance and market values of the 19 collateral properties, our satisfying certain financial covenants and other credit facility conditions.

Interest payable on borrowings under our credit agreement was previously at a rate of the secured overnight financing rate plus a margin of 350 basis points through the Petition Date. Effective on the Petition Date, interest payable on borrowings under our credit agreement changed to a rate of the U.S. federal prime rate plus a margin of 250 basis points. Effective February 4, 2026, in accordance with an order entered by the Bankruptcy Court, the margin increased to 450 basis points pursuant to the default rate stipulated in our credit agreement. We are also required to pay an unused facility fee on the amount of total lending commitments of 25 basis points per annum based on amounts outstanding. As of March 31, 2026 and May 18, 2026, our $325,000 revolving credit facility was fully drawn and $100,000 was outstanding under our term loan. As of March 31, 2026, the annual interest rate payable on borrowings under our credit agreement was 11.3%. The weighted average annual interest rate for borrowings under our credit agreement for the three months ended March 31, 2026 and 2025 was 10.6% and 7.9%, respectively.

Our credit agreement and senior notes indentures and their supplements provide for acceleration of payment of all amounts due thereunder upon the occurrence and continuation of certain events of default, such as, in the case of our credit agreement, a change of control of us, which includes RMR ceasing to act as our business and property manager. Our credit agreement and senior notes indentures and their supplements also contain covenants, including covenants that restrict our ability to incur debts, require us to comply with certain financial covenants and, in the case of our credit agreement, restrict our ability to increase our distribution rate above the level of $0.01 per common share per quarter. The filing of the Chapter 11 Cases constituted an event of default under our credit agreement and senior notes indentures and their supplements which accelerated amounts due under the applicable agreements. Efforts to enforce financial obligations under the applicable agreements are stayed as a result of the filing of the Chapter 11 Cases and the creditors' rights of enforcement are subject to the applicable provisions of the Bankruptcy Code. Our credit agreement is being amended and restated pursuant to the Plan to resolve any defaults thereunder and address certain terms to facilitate the Debtors' restructuring. The amended and restated credit agreement will become effective on the effective date of the Plan.

As of March 31, 2026, seven of our properties with an aggregate gross book value of real estate assets of $305,938 were encumbered by mortgage notes, or our Mortgage Notes, with an aggregate principal amount of $177,320. Our Mortgage Notes are non-recourse, subject to certain limited exceptions and do not contain any material financial covenants. The borrowers under our Mortgage Notes, or the Mortgage Note Borrowers, are certain of our subsidiaries that are not included in the Chapter 11 Cases. However, we provide certain guarantees under our Mortgage Notes, and as a result, the filing of the Chapter 11 Cases constituted an event of default under our Mortgage Notes and each Mortgage Note was transferred to special servicing. The Mortgage Note Borrowers continue to own, operate and lease the applicable collateral properties and remain current on their debt service obligations. As of May 18, 2026, two of the Mortgage Note Borrowers have entered into waiver agreements with their respective lenders. We remain in negotiation with the special servicers and lenders of our other Mortgage Notes regarding potential waiver agreements.

Our senior secured notes due 2027 require quarterly principal repayments of $6,500. We did not make any required principal payments during the three months ended March 31, 2026.

*DIP Term Loan Credit Agreement*

On November 5, 2025, the Bankruptcy Court entered an interim order allowing us to enter into a second debtor-in-possession term loan credit agreement, or the Initial DIP Credit Agreement. The Initial DIP Credit Agreement provided for a multiple draw secured debtor-in-possession term loan facility in an aggregate principal amount of up to $125,000. An initial borrowing of $10,000 was made following the entry of the interim order and our entry into the Initial DIP Credit Agreement on November 6, 2025.

On February 5, 2026, we entered into an amended and restated DIP term loan credit agreement, or the A&R DIP Credit Agreement pursuant to a final order entered by the Bankruptcy Court on February 4, 2026. The A&R DIP Credit Agreement provides for the DIP Facility, a multiple draw secured debtor-in-possession term loan facility in an aggregate principal amount of up to $125,000, of which: (a) we borrowed $10,000 on November 6, 2025 pursuant to an interim order entered by the Bankruptcy Court; (b) $75,000 was made available to us and drawn as follows: (i) we borrowed $64,300 on February 5, 2026, and (ii) we borrowed $10,700 on March 13, 2026; and (c) we borrowed $40,000, or the Tranche B Term Loan, on April 7, 2026. The DIP Facility had an original maturity date of May 4, 2026, with the option to extend under circumstances. In May 2026, the maturity date was extended to May 31, 2026. Borrowings under the DIP Facility may be repaid in reorganized common equity or cash, at the Debtors' election. On April 5, 2026, the Debtors filed and notice of their intent to equitize the DIP Facility with the Bankruptcy Court.

Borrowings under the DIP Facility bear interest, payable in cash, at a rate of 12.00% per annum. Fees and expenses under the DIP Facility include: (a) an upfront fee equal to (i) cash at 2.25% of the lenders' commitments or (ii) common equity of the reorganized OPI in an aggregate amount equal to 3.60% of the commitments, which fee was earned upon the initial funding of each loan under the DIP Facility and is payable in kind; (b) an anchor capital commitment fee of 10.00% of the lenders' commitments under the DIP Facility payable to certain backstop parties, which was earned upon the initial funding of the DIP Facility, and may be paid, at our election, in cash or common equity of the reorganized company; and (c) an exit fee of 4.50% of the aggregate borrowings under the DIP Facility, which is due and payable upon the repayment of any loans under the DIP Facility, at our election, in cash or common equity of the reorganized company. In the event of a voluntary prepayment, we are required to pay, for the ratable account of each lender, in cash a prepayment premium equal to 1.0% multiplied by the sum of the principal amount of the borrowings that are being repaid at such time. A commitment fee is also due for the ratable account of each Tranche B Term Loan lender, in an aggregate amount equal to 0.75% per annum times the actual daily amount of the aggregate undrawn Tranche B Term Loan commitments.

The DIP Facility contains customary conditions precedent, representations and warranties, affirmative and negative covenants, milestones for the Chapter 11 Cases, events of default and other terms and conditions customary for financings of this type. The DIP Facility obligations are entitled to superpriority administrative expense claims and secured by first-priority liens on certain of our unencumbered assets and junior-priority liens on certain of our encumbered assets.

(1)Includes net unamortized debt premiums, discounts and issuance costs totaling $20,449 and $22,115 as of March 31, 2026 and December 31, 2025, respectively.

We estimated the fair values of our senior notes (except for our senior priority guaranteed unsecured notes due 2030 and senior unsecured notes due 2050) using an average of the bid and ask price of the notes (Level 2 inputs as defined in the fair value hierarchy under GAAP) as of the measurement date. We estimated the fair value of our senior unsecured notes due 2050 based on the closing price on the OTC Pink Market, (Level 2 inputs as defined in the fair value hierarchy under GAAP) as of the measurement date. We estimated the fair values of our senior unsecured notes due 2030 and our mortgage notes payable using discounted cash flow analyses and currently prevailing market rates (Level 3 inputs as defined in the fair value hierarchy under GAAP) as of the measurement date. Because Level 3 inputs are unobservable, our estimated fair values may differ materially from the actual fair values. The fair values presented are estimates and may not represent what investors may expect to receive as a result of the Chapter 11 Cases.

**Note 9. Business and Property Management Agreements with RMR**

We have no employees. The personnel and various services we require to operate our business are provided to us by RMR. We have two agreements with RMR to provide management services to us: (1) a business management agreement, which relates to our business generally; and (2) a property management agreement, which relates to our property level operations.

We are generally responsible for all of our operating expenses, including certain expenses incurred or arranged by RMR on our behalf. We are generally not responsible for payment of RMR's employment, office or administrative expenses incurred to provide management services to us, except for the employment and related expenses of RMR's employees assigned to work exclusively or partly at our properties, our share of the wages, benefits and other related costs of RMR's centralized accounting personnel, our share of RMR's costs for providing our internal audit function and as otherwise agreed. Our property level operating expenses are generally incorporated into the rents charged to our tenants, including certain payroll and related costs incurred by RMR.

For the three months ended March 31, 2026 and 2025, the business management fees, property management fees and construction supervision fees and expense reimbursements recognized in our condensed consolidated financial statements were as follows:

(1)The net business management fees we recognized for the three months ended March 31, 2026 and 2025 each reflect a reduction of $151 for the amortization of the liability we recorded in connection with our former investment in The RMR Group Inc., or RMR Inc.

(2)The net property management fees we recognized for the three months ended March 31, 2026 and 2025 each reflect a reduction of $121 for the amortization of the liability we recorded in connection with our former investment in RMR Inc.

(3)Amounts capitalized as buildings and improvements are depreciated over the estimated useful lives of the related assets.

Based on our common share total return, as defined in our business management agreement, as of March 31, 2026, no estimated incentive fees are included in the net business management fees we recognized for the three months ended March 31, 2026. The actual amount of annual incentive fees for 2026, if any, will be based on our common share total return for the three year period ending December 31, 2026, and will be payable in January 2027. We did not incur an incentive fee payable to RMR for the year ended December 31, 2025. See Note 1 for further information regarding our agreements with RMR as it relates to the Plan.

*Management Agreement Between Our Joint Venture and RMR*. RMR provides management services to our unconsolidated joint venture. We are not obligated to pay management fees to RMR under our management agreement with RMR for the services it provides regarding the joint venture. The joint venture pays management fees directly to RMR.

**Note 10. Related Person Transactions**

We have relationships and historical and continuing transactions with RMR, RMR Inc. and others related to them, including other companies to which RMR or its subsidiaries provide management services and some of which have trustees, directors or officers who are also our Trustees or officers.

Board of Trustees and one of our Managing Trustees, Adam 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 vice president of RMR Inc. and an officer and employee of RMR. Each of our other officers is also an officer and employee of RMR. Some of our Independent Trustees also serve as independent trustees of other public companies to which RMR or its subsidiaries provide management services. Mr. Portnoy serves as chair of the boards and as a managing trustee of these public companies. Other officers of RMR, including Ms. Duffy, serve as managing trustees or officers of certain of these public companies.

*Our Manager, RMR.* We have two agreements with RMR to provide management services to us. RMR also provides management services to our unconsolidated joint venture. See Note 10 for more information regarding our and our unconsolidated joint venture's management agreement with RMR.

*Leases with RMR.* We lease office space to RMR in certain of our properties for RMR's property management offices. Pursuant to our lease agreements with RMR, we recognized rental income from RMR for leased office space of $180 and $201 for the three months ended March 31, 2026 and 2025, respectively.

*Sonesta.* Sonesta International Hotels Corporation, or Sonesta, operates a 246,000 square foot hotel within a mixed-use property in Washington D.C. under a management agreement that expires on December 31, 2040, and includes two 10-year renewal options. The Sonesta Management Agreement provides that we are paid an annual owner's priority return if gross revenues of the hotel, after payment of hotel operating expenses and management and related fees (other than Sonesta's incentive fee, if applicable), are sufficient to do so. The Sonesta Management Agreement further provides that we are paid an additional return of the operating profits, as defined therein, after paying the owner's priority return, reimbursing owner or manager advances, funding furniture, fixtures and equipment, or FF&E, reserves and paying Sonesta's incentive fee, if applicable. The stated annual owner's priority return is $7,500 and increases by 8.0% of our out-of-pocket capital expenditures and will increase annually to 102% of our prior year's annual owner's priority return. We recognized $7,102 and $7,153 of hotel operating revenues for the three months ended March 31, 2026 and 2025, respectively, which is included in rental income in our condensed consolidated statements of comprehensive income (loss). We realized returns under the Sonesta Management Agreement of $815 and $910 during the three months ended March 31, 2026 and 2025, respectively. We are responsible for any capital expenditures in excess of available funds in the FF&E reserve. Our annual priority return under the Sonesta Management Agreement as of March 31, 2026 was $7,637. The Sonesta Management Agreement requires that 1.0% of gross revenues for 2025, 3.0% of gross revenues for 2026 and 4.0% of gross revenues for each calendar year thereafter be escrowed for future capital expenditures as FF&E reserves. FF&E escrow deposits of $213 and $81 were required during the three months ended March 31, 2026 and 2025, respectively. Sonesta owed us $685 and $231 in returns under the Sonesta Management Agreement as of March 31, 2026 and December 31, 2025, respectively. Amounts due from Sonesta are included in due from related persons in our condensed consolidated balance sheets.

Pursuant to the Sonesta Management Agreement, we are required to pay Sonesta, after payment of hotel operating expenses, a base management fee equal to 1.5% of gross revenues, as defined in the Sonesta Management Agreement, for 2025 and 3.0% of gross revenues each calendar year thereafter. Additionally, we are required to pay (i) an incentive fee equal to 20% of net operating profit, as defined in the Sonesta Management Agreement, in excess of the annual owner's priority; (ii) a brand promotion fee of 1.75% of gross revenues for 2025 and 3.5% of gross revenues for each calendar year thereafter; and (iii) a loyalty fee of the greater of 1.0% of room revenues or 4.5% of qualified room revenues from guests participating in certain loyalty programs. Sonesta's incentive management fee, but not its other fees, is earned only after our annual owner's priority return is paid. The Sonesta Management Agreement also provides that the pro rata costs Sonesta incurs for advertising, marketing, promotional and public relations programs and campaigns, including its Rewards Program, for the benefit of this hotel are subject to reimbursement by us or are otherwise treated as hotel operating expenses.

We incurred management, brand promotion and loyalty fees of $446 and $361 for the three months ended March 31, 2026 and 2025, respectively. These fees and costs are included in other operating expenses in our condensed consolidated statements of comprehensive income (loss). We are required to maintain working capital under the Sonesta Management Agreement and advanced $548 of working capital in 2025 to meet the cash needs for hotel operations.

We are amortizing a straight line rent receivable through July 2053, the original expiration date of a prior lease for the hotel with Sonesta, as an increase to other operating expenses in our condensed consolidated statements of comprehensive income (loss).

**Note 11. Segment Reporting**

We manage our business on a consolidated basis and therefore have one reportable segment: ownership and leasing of real estate properties. The chief operating decision maker, or CODM, is our President and Chief Executive Officer. The CODM assesses performance, allocates resources and makes strategic decisions based on net income (loss) as shown in our condensed consolidated statements of comprehensive income (loss). The CODM is also regularly provided with information on expenses related to our management agreements with RMR, which are detailed in Note 10. The measure of segment assets is reported as total assets in our condensed consolidated balance sheets.

**Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations**

The following information should be read in conjunction with our Condensed Consolidated Financial Statements and accompanying notes included in Part I, Item 1 of this Quarterly Report on Form 10-Q and with our 2025 Annual Report.

**OVERVIEW (dollars in thousands, except per share and per square foot data)**

We are a REIT organized under Maryland law. As of March 31, 2026, our wholly owned properties were comprised of 122 properties and we had a noncontrolling ownership interest of 51% in an unconsolidated joint venture that owned two properties containing approximately 346,000 rentable square feet. As of March 31, 2026, our properties are located in 29 states and the District of Columbia and contain approximately 17,113,000 rentable square feet. As of March 31, 2026, our properties were leased to 209 different tenants with a weighted average remaining lease term (based on annualized rental income) of approximately 6.4 years. The U.S. government is our largest tenant, representing approximately 17.5% of our annualized rental income as of March 31, 2026. The term annualized rental income as used herein is defined as the annualized contractual base rents from our tenants pursuant to our lease agreements as of March 31, 2026, plus straight line rent adjustments and estimated recurring expense reimbursements to be paid to us, and excluding lease value amortization.

Leases representing approximately $22,248, or 5.7%, of our annualized rental income, are scheduled to expire on or before March 31, 2027 and we may be unable to renew leases or find replacement tenants. Certain shifts in office space utilization, including increased remote work arrangements and tenants consolidating their real estate footprint, as well as ongoing market and economic conditions, including government spending and budget priorities, continue to impact the office sector and our portfolio. The demand for office space continues to face headwinds, including in markets where we have a concentration of properties, such as Washington, D.C., and declining rents and increasing costs to relet space when tenants can be identified continue to impact the market. The duration and ultimate impact of current trends on the demand for office space at our properties remains uncertain and subject to change. Higher interest rates, inflationary pressures, changes in government policies including the potential reduction of U.S. federal office leases and potential impacts from tariffs, geopolitical events or an economic recession, continue to cause disruptions in 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. In addition, prospective tenants may delay their decision to lease space due to current economic conditions. 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 at our properties.

*Chapter 11 Bankruptcy Proceedings*

On the Petition Date, the Debtors voluntarily commenced the Chapter 11 Cases. In connection with the filing of the Chapter 11 Cases, we entered into the RSA with certain holders of the September 2029 Notes to implement a court-supervised financial restructuring pursuant to the transactions contemplated in the RSA.

We continue to operate our 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, we are authorized to pay all debts and honor all obligations arising in the ordinary course of our business after the Petition Date. However, generally, we 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 these proceedings 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 the Plan may not become effective.

The Plan has not yet become effective as of the date of filing of this Quarterly Report on Form 10-Q. 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. For more information regarding the Chapter 11 Cases, the RSA and the Plan, including the material terms thereof, see Note 1 to our Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

*Going Concern*

Substantial doubt about our ability to continue as a going concern exists due to (1) insufficient liquidity to satisfy our obligations as they come due, (2) limited alternatives available to us to obtain debt or equity financing, (3) inability to refinance our maturing debt, and (4) the resulting Chapter 11 Cases. Our ability to continue as a going concern is contingent upon, among other things, our ability to, subject to the approval by the Bankruptcy Court, implement a plan of reorganization, emerge from

------

<u>[**Table of Contents**](#i344599fd3d9f4b58890a408cc8032277_10)</u>

the Chapter 11 proceedings and generate sufficient liquidity following the reorganization to meet our obligations, restructured debt obligations and operating needs.

The transactions contemplated by the Plan are subject to approval by the Bankruptcy Court, among other conditions. Accordingly, no assurance can be given that the transactions described therein will be consummated. As a result, we have concluded that management's plans at this stage do not alleviate substantial doubt about our ability to continue as a going concern.

For more information about the risks relating to these dynamics and conditions and their impacts on us and our business, see Part I, Item IA, "Risk Factors", of our 2025 Annual Report.

*Nasdaq Delisting*

On September 25, 2025, 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.

During the three months ended March 31, 2026 and 2025, amounts capitalized at our properties for lease related costs, building improvements and development, redevelopment and other activities were as follows:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** |
| | **2026** | **2025** |
| Lease related costs <sup>(1)</sup> | $8458 | $10727 |
| Building improvements <sup>(2)</sup> | 2350 | 3011 |
| &nbsp;&nbsp;&nbsp;Recurring capital expenditures | 10808 | 13738 |
| Development, redevelopment and other activities <sup>(3)</sup> | 109 | 83 |
| &nbsp;&nbsp;&nbsp;Total capital expenditures | $10917 | $13821 |

---

(1)Lease related costs generally include capital expenditures used to improve tenants' space or amounts paid directly to tenants to improve their space and leasing related costs, such as brokerage commissions and other tenant inducements.

(2)Building improvements generally include expenditures to replace obsolete building components and expenditures that extend the useful life of existing assets.

(3)Development, redevelopment and other activities generally include capital expenditure projects that reposition a property or result in new sources of revenue.

As of March 31, 2026, we had estimated unspent leasing related obligations of $54,390, of which we expect to spend $35,186 over the next 12 months.

As of March 31, 2026, we had leases at our properties totaling approximately 801,000 rentable square feet that were scheduled to expire on or before March 31, 2027. As of May 18, 2026, we expect tenants with leases totaling approximately 196,000 rentable square feet that are scheduled to expire on or before March 31, 2027, excluding space that has been re-leased and space for which we are in advanced negotiations to re-lease, not to renew or to downsize their leased space upon expiration, and we cannot be sure as to whether other tenants will renew their leases upon expiration. We continue to proactively engage with our existing tenants and are focused on overall tenant retention. Prevailing market conditions and our tenants' needs at the time we negotiate and enter leases or lease renewals will generally determine rental rates and demand for leased space at our properties, all of which are beyond our control. Whenever we renew or enter into new leases for our properties, we intend to seek rents which are equal to or higher than our historical rents for the same properties; however, our ability to maintain or increase the rents for our properties will depend in large part upon market conditions, which are beyond our control. We cannot be sure of the rental rates that will result from our ongoing negotiations regarding lease renewals or any new or renewed leases we may enter. Also, we may experience material declines in our rental income due to vacancies upon lease expirations, early terminations or lower rents upon lease renewal or reletting. Additionally, we may incur significant costs and make significant concessions to renew leases with current tenants or attract new tenants to our properties.

---

(1)The year of lease expiration is pursuant to current contract terms. Some of our leases allow the tenants to vacate the leased premises before the stated expirations of their leases with little or no liability. As of March 31, 2026, tenants occupying approximately 2.2% of our rentable square feet and responsible for approximately 2.8% of our annualized rental income as of March 31, 2026 had exercisable rights to terminate their leases before the stated terms of their leases expire. Also, in 2026, 2027, 2028, 2029, 2030, 2031, 2032, 2034, 2035, 2036 and 2037, early termination rights become exercisable by other tenants who occupied an additional approximately 0.5%, 1.5%, 5.3%, 3.2%, 2.4%, 0.7%, 4.3%, 0.3%, 1.1%, 0.2% and 0.2%, of our rentable square feet, respectively, and contributed an additional approximately 0.9%, 2.2%, 6.4%, 3.1%, 3.0%, 0.8%, 5.6%, 0.9%, 1.6%, 0.4% and 0.3% of our annualized rental income, respectively, as of March 31, 2026. In addition, as of March 31, 2026, pursuant to leases with six of our tenants, these tenants had rights to terminate their leases if their respective legislature or other funding authority does not appropriate rent amounts in their respective annual budgets. These six tenants occupied approximately 4.5% of our rentable square feet and contributed approximately 4.9% of our annualized rental income as of March 31, 2026.

(2)Leased square feet is pursuant to leases existing as of March 31, 2026, and includes (i) space being fitted out for tenant occupancy pursuant to our lease agreements, if any, and (ii) space which is leased, but is not occupied or is being offered for sublease by tenants, if any. Square feet measurements are subject to changes when space is remeasured or reconfigured for new tenants.

We generally will seek to renew or extend the terms of leases at properties with tenants when they expire. However, market and economic factors, along with increases in remote work, changes in space utilization and government policies, spending and budget priorities, may cause our tenants not to renew or extend their leases when they expire, or to seek to renew their leases for less space than they currently occupy. If we are unable to extend or renew our leases, or we renew leases for reduced space, it may be time consuming and expensive to relet our properties.

As of March 31, 2026, we derived 23.2% of our annualized rental income from our properties located in the metropolitan Washington, D.C. market area, which includes Washington, D.C., Northern Virginia and suburban Maryland. Current economic conditions in this area or a possible recession could reduce demand from tenants at our properties, reduce rents that our tenants are willing to pay when our leases expire or increase lease concessions for new leases and renewals. Additionally, although the current administration has issued so called return to work mandates, there has been a decrease in demand for leased office space by the U.S. government, including in the metropolitan Washington, D.C. market area, which could increase competition for government tenants and adversely affect our ability to retain government tenants or maintain or increase our rents when leases expire.

Our manager, RMR, employs a tenant review process for us. RMR assesses tenants on an individual basis based on various applicable credit criteria. In general, depending on facts and circumstances, RMR evaluates the creditworthiness of a tenant based on information concerning the tenant that is provided by the tenant and, in some cases, information that is publicly available or obtained from third party sources. We consider investment grade tenants to include: (a) investment grade rated tenants; (b) tenants with investment grade rated parent entities that guarantee the tenant's lease obligations; and/or (c) tenants with investment grade rated parent entities that do not guarantee the tenant's lease obligations. As of March 31, 2026, tenants contributing 59.6% of annualized rental income were investment grade rated (or their payment obligations were guaranteed by an investment grade rated parent) and tenants contributing an additional 0.5% of annualized rental income were subsidiaries of an investment grade rated parent (although these parent entities were not liable for the payment of rents).

n/m - not meaningful

(1)Comparable properties consists of 117 properties we owned on March 31, 2026 and which we owned continuously since January 1, 2025 and excludes five properties affected by significant redevelopment activities and two properties owned by an unconsolidated joint venture in which we own a 51% interest.

(2)Our definition of net operating income, or NOI, and our reconciliation of Net loss to NOI are included below under the heading "Non-GAAP Financial Measures."

References to changes in the income and expense categories below relate to the comparison of consolidated results for the three months ended March 31, 2026, compared to the three months ended March 31, 2025.

*Rental income.* Rental income decreased $4,157 for comparable properties as a result of increased vacancies and lower rents from lease renewals at certain of our properties in the 2026 period and $590 related to our property disposition activities. Rental income includes non-cash straight line rent adjustments totaling $1,936 in the 2026 period and $6,856 in the 2025 period, and amortization of acquired real estate leases and assumed real estate lease obligations totaling $140 in the 2026 period and $123 in the 2025 period.

------

<u>[**Table of Contents**](#i344599fd3d9f4b58890a408cc8032277_10)</u>

*Real estate taxes.* Real estate taxes decreased $249 related to our property disposition activities, $74 for comparable properties and $41 for properties affected by significant redevelopment activities.

*Utility expenses.* Utility expenses increased $1,731 for comparable properties due to higher electricity usage and rates in the 2026 period, partially offset by decreases of $144 for properties affected by significant redevelopment activities and $75 related to our property disposition activities.

*Other operating expenses.* Other operating expenses decreased $730 for comparable properties due to lower repairs and maintenance costs in the 2026 period and $298 related to our property disposition activities, partially offset by an increase of $105 related to properties affected by significant redevelopment activities.

*Depreciation and amortization.* Depreciation and amortization increased $424 for comparable properties and $110 for properties affected by significant redevelopment activities related to improvements made at certain of our properties since January 1, 2025, partially offset by a decrease of $184 related to our property disposition activities.

*Transaction related costs.* Transaction related costs in the 2025 period consist of costs related to our evaluation of potential financing transactions.

*General and administrative.* The decrease in general and administrative expenses is primarily the result of a decrease in base business management fees resulting from a decrease in average total market capitalization, lower public company costs during the pendency of the Chapter 11 Cases and a decrease in share-based compensation in the 2026 period compared to the 2025 period.

*Loss on sale of real estate.* We recorded a $4,737 loss on sale of real estate resulting from the sale of one property in the 2025 period.

*Interest and other income.* The decrease in interest and other income is primarily due to lower cash balances invested and the effect of lower interest rates earned on cash balances invested in the 2026 period compared to the 2025 period.

*Interest expense.* The decrease in interest expense is primarily due to our adoption of Financial Accounting Standards Board Accounting Standards Codification, or ASC, Topic 852, *Reorganizations,* or ASC 852, as a result of the Chapter 11 Cases, pursuant to which we ceased recognition of interest expense on our senior unsecured notes and wrote-off unamortized discounts and issuance costs related to liabilities subject to compromise, or LSTC, as of the Petition Date, resulting in lower amortization expense in the 2026 period. For more information regarding our adoption of ASC 852 and the Chapter 11 Cases, see Notes 1 and 2 to our Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

*Net loss on early extinguishment of debt*. We recorded a net loss on early extinguishment of debt of $243 in the 2025 period related to a senior note exchange and the write off of unamortized discounts and issuance costs related to the partial redemption of our senior secured notes due 2027.

*Reorganization Items, net.* Reorganization items, net represent amounts incurred after the Petition Date as a direct result of the Chapter 11 Cases and are comprised of bankruptcy-related professional fees and adjustments to reflect the carrying value of LSTC at their estimated allowed claim amounts. For more information regarding reorganization items, net and the Chapter 11 Cases, see Notes 1 and 2 to our Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

*Income tax benefit (expense).* Income tax benefit (expense) is primarily the result of operating income earned in jurisdictions where we are subject to state income taxes and can fluctuate based on the timing of our income, including as a result of gains or losses on the sale of real estate or the repayment of debt.

*Equity in net earnings (losses) of investees.* Equity in net earnings (losses) of investees represents our proportionate share of earnings (losses) from our investment in our unconsolidated joint venture.

*Net loss.* Net loss and net loss per basic and diluted common share changed in the 2026 period compared to the 2025 period primarily as a result of the changes noted above.

**Non-GAAP Financial Measures**

We present certain "non-GAAP financial measures" within the meaning of the applicable SEC rules, including the calculations below of NOI, funds from operations, or FFO, and normalized funds from operations, or Normalized FFO. 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 our operating performance or as measures of our liquidity. These measures should be considered in conjunction with net income (loss) as presented in our condensed consolidated statements of comprehensive income (loss). We consider these non-GAAP measures to be appropriate supplemental measures of operating performance for a REIT, along with net income (loss). We believe 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 our operating performance between periods and with other REITs and, in the case of 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 our properties.

*Net Operating Income* 

The calculation of NOI excludes certain components of net income (loss) in order to provide results that are more closely related to our property level results of operations. We calculate NOI as shown below. We define NOI as income from our rental of real estate less our property operating expenses. NOI excludes amortization of capitalized tenant improvement costs and leasing commissions that we record as depreciation and amortization expense. We use NOI to evaluate individual and company-wide property level performance. Other real estate companies and REITs may calculate NOI differently than we do.

The following table presents the reconciliation of net loss to NOI for the three months ended March 31, 2026 and 2025:

---

*Funds From Operations and Normalized Funds From Operations*

We calculate FFO and Normalized FFO as shown below. FFO is calculated on the basis defined by The National Association of Real Estate Investment Trusts, which is net income (loss), calculated in accordance with GAAP, plus real estate depreciation and amortization of consolidated properties and our 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, we adjust for the other items shown below and include 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 our 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 our Board of Trustees when determining the amount of distributions to our shareholders. Other factors include, but are not limited to, requirements to maintain our qualification for taxation as a REIT, limitations in our credit agreement and public debt covenants, the availability to us of debt and equity capital, our expectation of our future capital requirements and operating performance and our expected needs for and availability of cash to pay our obligations. Other real estate companies and REITs may calculate FFO and Normalized FFO differently than we do.

The following table presents the reconciliation of net income (loss) to FFO and Normalized FFO for the three months ended March 31, 2026 and 2025:

**LIQUIDITY AND CAPITAL RESOURCES**

***Our Operating Liquidity and Resources (dollar amounts in thousands, except per share amounts)***

Our historical principal sources of funds to meet operating and capital expenses, pay debt service obligations and make distributions to our shareholders are the operating cash flows we generate from our properties, net proceeds from property sales and borrowings under our revolving credit facility.

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, until the effectiveness of the Plan, will require Bankruptcy Court approval in most instances. Accordingly, our liquidity primarily depends on cash generated from operating activities and borrowings under our DIP Facility. The filing of the Chapter 11 Cases constituted an event of default under our credit agreement, senior notes indentures and their supplements and mortgage notes which accelerated amounts due under the applicable agreements. Efforts to enforce financial obligations under the applicable agreements are stayed as a result of the filing of the Chapter 11 Cases and the creditors' rights of enforcement are subject to the applicable provisions of the Bankruptcy Code. Our credit agreement is being amended and restated pursuant to the Plan to resolve any defaults thereunder and address certain terms to facilitate the Debtors' restructuring. The amended and restated credit agreement will become effective on the effective date of the Plan.

------

<u>[**Table of Contents**](#i344599fd3d9f4b58890a408cc8032277_10)</u>

Our future cash flows from operating activities will depend primarily upon:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to collect rent from our tenants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to maintain or increase the occupancy of, and the rental rates at, our properties;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to control operating and capital expenses at our properties; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to successfully sell properties that we market for sale.

The office industry has been adversely affected by shifts in office space utilization, including increased remote work arrangements and tenants consolidating their real estate footprint, as well as ongoing market and economic conditions, including government spending and budget priorities. Demand for office space continues to face headwinds, including in markets where we have a concentration of properties, such as Washington, D.C., and the duration and ultimate impact of current trends on our properties remains uncertain and subject to change. These conditions continue to have a significant negative impact on our results of operations, financial position and cash flows.

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 improve our liquidity. As of May 18, 2026, we have entered into an agreement to sell one property containing approximately 275,000 rentable square feet for a sales price of $18,125, excluding closing costs. We expect to sell this property in 2027. This pending sale is subject to conditions; accordingly, we cannot be sure that we will complete this sale or that this sale will not be delayed or the pricing will not change. We are also at various stages of marketing for sale 31 properties with a total of approximately 3,416,000 square feet. We expect to use the net sales proceeds from property sales to repay debt. There can be no assurance we will be successful selling any of these properties or what the amount of proceeds we may realize will be.

The following is a summary of our sources and uses of cash flows for the periods presented, as reflected in our condensed consolidated statements of cash flows:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** |
| | **2026** | **2025** |
| Cash, cash equivalents and restricted cash at beginning of period | $80661 | $275165 |
| Net cash provided by (used in): |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Operating activities | (52942) | (28588) |
| &nbsp;&nbsp;&nbsp;&nbsp;Investing activities | (15029) | 15034 |
| &nbsp;&nbsp;&nbsp;&nbsp;Financing activities | 75000 | (184957) |
| Cash, cash equivalents and restricted cash at end of period | $87690 | $76654 |

---

The increase in cash used in operating activities in the 2026 period was primarily due to professional fees paid in connection with the Chapter 11 Cases and decreased NOI related to reductions in occupied space at certain of our properties in the 2026 period. The change from cash provided by investing activities in the 2025 period to cash used in investing activities in the 2026 period was primarily due to lower proceeds from property sales and increased capital expenditures in the 2026 period. The change from cash used in financing activities in the 2025 period to cash provided by financing activities in the 2026 period was primarily due to the repayment of our senior unsecured notes due 2025 in the 2025 period and borrowings under our DIP Facility in the 2026 period.

***Our Investment and Financing Liquidity and Resources (dollar amounts in thousands, except per share amounts)***

In order to meet cash needs to pay operating or capital expenses during the pendency of the Chapter 11 Cases, we have relied on borrowings under our secured $125,000 DIP Facility. We have made the following borrowings under the DIP Facility: (a) we borrowed $10,000 on November 6, 2025 pursuant to an interim order entered by the Bankruptcy Court; (b) $75,000 was made available to us and drawn as follows: (i) we borrowed $64,300 on February 5, 2026, and (ii) we borrowed $10,700 on March 13, 2026; and (c) we borrowed $40,000, or the Tranche B Term Loan, on April 7, 2026. Borrowings under the DIP Facility bear interest, payable in cash, at a rate of 12.00% per annum. The DIP Facility had an original maturity date of May 4, 2026, with the option to extend under certain circumstances. In May 2026, the maturity date was extended to May 31, 2026. Borrowings under the DIP Facility may be repaid in reorganized common equity or cash, at the Debtors' election. On April 5, 2026, the Debtors filed a notice of their intent to equitize the DIP Facility with the Bankruptcy Court. Fees and expenses under the DIP Facility include: (a) an upfront fee equal to (i) cash at 2.25% of the lenders' commitments or (ii) common equity of the

------

<u>[**Table of Contents**](#i344599fd3d9f4b58890a408cc8032277_10)</u>

reorganized OPI in an aggregate amount equal to 3.60% of the commitments, which fee was earned upon the initial funding of each loan under the DIP Facility and is payable in kind; (b) an anchor capital commitment fee of 10.00% of the lenders' commitments under the DIP Facility payable to certain backstop parties, which was earned upon the initial funding of the DIP Facility, and may be paid, at our election, in cash or common equity of the reorganized company; and (c) an exit fee of 4.50% of the aggregate borrowings under the DIP Facility, which is due and payable upon the repayment of any loan under the DIP Facility, at our election, in cash or common equity of the reorganized company. In the event of a voluntary prepayment, we are required to pay, for the ratable account of each lender, in cash a prepayment premium equal to 1.0% multiplied by the sum of the principal amount of the borrowings that are being repaid at such time. A commitment fee is also due for the ratable account of each Tranche B Term Loan lender, in an aggregate amount equal to 0.75% per annum times the actual daily amount of the aggregate undrawn Tranche B Term Loan commitments. As of March 31, 2026 and May 18, 2026, the outstanding principal balance under our DIP Facility was $86,913 and $127,813, respectively, including fees payable in kind.

Historically, in order to meet cash needs to pay operating or capital expenses and make distributions, we have maintained a revolving credit facility under our credit agreement. Our obligations under our credit agreement are secured by a pledge by certain of our subsidiaries of all of their respective equity interests in certain of our direct and indirect property owning subsidiaries and first mortgage liens on 19 properties owned by the pledged subsidiaries with a gross book value of real estate assets of $1,035,771 as of March 31, 2026. The maturity date of our credit agreement is January 29, 2027. Our credit agreement contains a number of covenants, including covenants that require us to maintain certain financial ratios, restrict our ability to incur additional debt in excess of calculated amounts and, subject to limited exceptions, restrict our ability to increase our distribution rate above $0.01 per common share per quarter and enter into share repurchases. Availability of borrowings under our credit agreement is subject to ongoing minimum performance and market values of the 19 collateral properties, our satisfying certain financial covenants and other credit facility conditions.

Interest payable on borrowings under our credit agreement was at a rate of the secured overnight financing rate plus a margin of 350 basis points through the Petition Date. Effective on the Petition Date, interest payable on borrowings under our credit agreement changed to a rate of the U.S. federal prime rate plus a margin of 250 basis points. Effective February 4, 2026, in accordance with an order entered by the Bankruptcy Court, the margin increased to 450 basis points pursuant to the default rate stipulated in our credit agreement. We are also required to pay an unused facility fee on the amount of total lending commitments, which was 25 basis points per annum at March 31, 2026. As of March 31, 2026, the annual interest rate payable on borrowings under our credit agreement was 11.3%. As of March 31, 2026, and May 18, 2026, our $325,000 revolving credit facility was fully drawn and $100,000 was outstanding under our term loan.

Our senior secured notes due 2027 require quarterly principal repayments of $6,500 and an additional $117,502 principal repayment in March 2026. As of March 31, 2026, we have made $19,500 of scheduled quarterly principal repayments on these notes in 2025. We ceased scheduled quarterly principal payments and did not make the additional March 2026 principal repayment following the commencement of the Chapter 11 Cases.

As of March 31, 2026, our debt maturities (other than our revolving credit facility), consisting of senior notes, our DIP Facility, a term loan and mortgage notes, were as follows:

---

| | |
|:---|:---|
| **Year** | **Debt Maturities** |
| 2026 | $220842 |
| 2027 | 596300 |
| 2028 | 123487 |
| 2029 | 910278 |
| 2030 | 14739 |
| 2031 and thereafter | 317656 |
| &nbsp;&nbsp;&nbsp;Total | $2183302 |

---

None of our unsecured debt obligations require sinking fund payments prior to their respective maturity dates. Our mortgage notes currently require monthly payments of interest only; however, certain of our mortgage notes will require payments of principal and interest after a specified date through maturity.

------

<u>[**Table of Contents**](#i344599fd3d9f4b58890a408cc8032277_10)</u>

In addition to our debt obligations, as of March 31, 2026, we had estimated unspent leasing related obligations of $54,390, of which we expect to spend $35,186 over the next 12 months.

As of May 18, 2026, our total available liquidity was comprised of $118,501, which included $56,253 of unrestricted cash and $62,248 of restricted cash. Substantial doubt about our ability to continue as a going concern exists due to (1) insufficient liquidity to satisfy our obligations as they come due, (2) limited alternatives available to us to obtain debt or equity financing, (3) inability to refinance our maturing debt, and (4) the resulting Chapter 11 Cases. Our ability to continue as a going concern is contingent upon, among other things, our ability to implement the Plan, emerge from the Chapter 11 proceedings and generate sufficient liquidity following the reorganization to meet our obligations, restructured debt obligations and operating needs.

We owned a 51% interest in an unconsolidated joint venture which owned two properties at March 31, 2026. As of March 31, 2026, the properties owned by this joint venture were encumbered by $48,877 principal amount of mortgage indebtedness, none of which is recourse to us. As of March 31, 2026, we did not control the activities that are most significant to this joint venture and, as a result, we accounted for our investment in this joint venture under the equity method of accounting. The filing of the Chapter 11 Cases constituted an event of default under the mortgage note secured by the properties owned by this joint venture. This joint venture remains current on debt service under this mortgage note and continues to own, operate and lease the collateral properties. For more information on the financial condition and results of operations of this joint venture, see Note 4 to our Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q. Other than this joint venture, as of March 31, 2026, we had no off balance sheet arrangements that have had or that we expect would be reasonably likely to have a material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

***Debt Covenants***

Our principal debt obligations as of March 31, 2026 consisted of (i) $325,000 of borrowings outstanding under our revolving credit facility, (ii) $100,000 outstanding principal amount under our secured term loan, (iii) an outstanding principal balance of $1,819,069 of senior notes, (iv) $86,913 outstanding under our DIP Facility and (v) mortgage notes with an outstanding principal balance of $177,320. Also, the two properties owned by the joint venture in which we own a 51% interest secure an additional mortgage note. Our senior notes are governed by indentures and their supplements. Our credit agreement, senior notes indentures and their supplements and the amended and restated debtor-in-possession term loan credit agreement governing our DIP Facility, or the DIP Credit Agreement, provide for acceleration of payment of all amounts due thereunder upon the occurrence and continuation of certain events of default, such as, in the case of our credit agreement, a change of control of us, which includes RMR ceasing to act as our business and property manager. Our credit agreement, senior notes indentures and their supplements and the DIP Credit Agreement also contain covenants, including covenants that restrict our ability to incur debts, require us to comply with certain financial covenants and, in the case of our credit agreement, restrict our ability to increase our distribution rate above the level of $0.01 per common share per quarter. The filing of the Chapter 11 Cases constituted an event of default under our credit agreement and senior notes indentures which accelerated amounts due under the applicable agreements. Efforts to enforce financial obligations under the applicable agreements are stayed as a result of the filing of the Chapter 11 Cases and the creditors' rights of enforcement are subject to the applicable provisions of the Bankruptcy Code.

***Related Person Transactions***

We have relationships and historical and continuing transactions with RMR, RMR Inc. and others related to them. For more information about these and other such relationships and related person transactions, see Notes 10 and 11 to our Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q, our 2025 Annual Report and our other filings with the SEC. In addition, see the section captioned "Risk Factors" in Part I, Item 1A of our 2025 Annual Report for a description of risks that may arise as a result of these and other related person transactions and relationships. We may engage in additional transactions with related persons, including businesses to which RMR or its subsidiaries provide management services.

***Critical Accounting Estimates***

The preparation of our Condensed Consolidated Financial Statements in conformity with GAAP requires us to make estimates and assumptions that affect reported amounts. Actual results could differ from those estimates. Significant estimates in the Condensed Consolidated Financial Statements include purchase price allocations, useful lives of fixed assets and assessment of impairment of real estate and the related intangibles.

A discussion of our critical accounting estimates is included in our 2025 Annual Report. There have been no significant changes in our critical accounting estimates since the year ended December 31, 2025.

**Item 3. Quantitative and Qualitative Disclosures About Market Risk** 

As a smaller reporting company, we are not required to make disclosures under this Item.

**Item 4. Controls and Procedures**

As of the end of the period covered by this Quarterly Report on Form 10-Q, our management carried out an evaluation, under the supervision and with the participation of our President and Chief Executive Officer and our Chief Financial Officer and Treasurer, of the effectiveness of our disclosure controls and procedures pursuant to Rules 13a-15 and 15d-15 under the Securities Exchange Act of 1934, as amended. Based upon that evaluation, our President and Chief Executive Officer and our Chief Financial Officer and Treasurer concluded that our disclosure controls and procedures were not effective as of such date due to our inability to file our periodic reports under the Exchange Act on a timely basis while we relied on the reporting accommodation available to certain registrants in Chapter 11 proceedings.

Notwithstanding the foregoing, our President and Chief Executive Officer and our Chief Financial Officer and Treasurer concluded that we maintained effective internal control over financial reporting as of the end of the period covered by this Quarterly Report on Form 10-Q.

There have been no changes in our internal control over financial reporting during the quarter ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

<u>Warning Concerning Forward-Looking Statements</u>

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and other securities laws that are subject to risks and uncertainties. These statements may include words such as "believe", "expect", "anticipate", "intend", "plan", "estimate", "will", "may" and negatives or derivatives of these or similar expressions.

Some of the risks, uncertainties and other factors that may cause our actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements include, but are not limited to, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The likelihood that our government tenants will be negatively impacted by government budget constraints, or changes in the use of real estate by government agencies,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to increase or maintain occupancy at our properties on terms desirable to us, and our ability to increase rents when our leases expire or renew,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Actual and potential conflicts of interest with our related parties, including our Managing Trustees, RMR, Sonesta and others affiliated with them,

The information contained in our filings with the SEC, including under the caption "Risk Factors" in the 2025 Annual Report and our other periodic reports, or incorporated herein or therein, identifies important factors that could cause differences from the forward-looking statements in this Quarterly Report on Form 10-Q. Our filings with the SEC are available on the SEC's website at www.sec.gov.

You should not place undue reliance upon our forward-looking statements.

Except as required by law, we do not intend to update or change any forward-looking statements as a result of new information, future events or otherwise.
