Organization, Consolidation and Presentation of Financial Statements [Abstract]

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.

Basis of Presentation

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.

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.

Liabilities Subject to Compromise.

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	$	1,519,069	$	1,519,069
Accrued interest	42,230		42,230
Accounts payable and other liabilities	8,108		16,834
Total liabilities subject to compromise	$	1,569,407	$	1,578,133

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

Contractual interest. Effective as of the Petition Date, we ceased accruing interest expense on our unsecured debt instruments.

Reorganization items

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.

Revenue

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.
