Exhibit 99.1

Star Holdings

Pro Forma Financial Information

In December 2023, Star Holdings (the “Company”) transferred the ownership interests in a subsidiary land owner to a third-party venture (the “Venture”) for its development and construction of a multifamily project in Asbury Park, NJ (the “Project”). In connection with this transfer, the Company (i) provided the Venture with a $10.6 million mezzanine loan that was fully funded at closing and was secured by the ownership interests in the subsidiary land owner and scheduled to mature in June 2033; and (ii) provided a completion and carry guaranty (the “Guaranty”) on the Venture’s $80.0 million senior construction mortgage loan with a third-party lender in return for a fee. The Company was a non-member manager of the Venture and entitled to certain fees, but otherwise had no expected member-related economics.

The Company determined that the Venture (and its consolidated subsidiaries developing the Project) was a variable interest entity for which the Company was the primary beneficiary and thus consolidated it under Accounting Standards Codification 810 (“ASC 810”). As a result, for accounting purposes, the Venture was recorded in the Company’s consolidated financial statements and the mezzanine loan eliminated in consolidation. On March 27, 2026, the mezzanine loan was repaid in full and the Guaranty was released. The Company also resigned as manager of the Venture in conjunction with the repayment of the mezzanine loan and the release of the Guaranty. As such, the Company no longer controls the decision-making of the Venture and the Venture was deconsolidated in accordance with ASC 810.

The unaudited condensed consolidated pro forma balance sheet and the unaudited condensed consolidated pro forma statement of operations assume that the deconsolidation of the Venture occurred on December 31, 2025 and January 1, 2025, respectively. The unaudited pro forma adjustments are based on available information and certain estimates and assumptions that the Company believes are directly attributable to the transaction.

Pro forma adjustments include: (i) the derecognition of all assets, liabilities, noncontrolling interests, revenues and expenses associated with the Venture; (ii) the transfer of miscellaneous operating accounts such as prepaid expenses and other assets, accrued expenses, unearned rents and other items; (iii) the recognition of a sale of a land and development asset to the Venture; and (iv) the transfer of restricted cash to unrestricted cash.

The pro forma consolidated balance sheet and statement of operations are presented for informational purposes only in accordance with Article 11 of Regulation S-X and is not necessarily indicative of what the Company's financial position or operations would have been for the periods presented, nor does it purport to represent the future financial position or operations of the Company. The pro forma financial information should be read in conjunction with the historical consolidated financial statements and notes thereto as filed in the Company's 2025 Annual Report on Form 10-K.

The pro forma impact to the Company’s consolidated balance sheet, assuming the deconsolidation of the Venture occurred on December 31, 2025, would be as follows: (in thousands)
