Item2.02. Results of Operations and Financial Condition.

On February 11, 2026, Shuttle Pharmaceuticals Holdings, Inc. (the “Company”) filed a registration statement on Form S-1 disclosing certain preliminary estimated unaudited financial results for the full year ended December 31, 2025. The text of the disclosure of those preliminary estimated unaudited financial results is included below.

PreliminaryEstimated Unaudited Financial Results for the Year Ended December 31, 2025

Set forth below are preliminary estimates of selected unaudited financial and other information as of and for the year ended December 31, 2025 and financial information as of and for the year ended December 31, 2024, certain of which was derived from the audited financial statements previously filed with the Company’s Annual Report on Form 10-K on February 26, 2025. The Company provided a range for the preliminary estimated financial results for 2025 because the Company’s closing procedures for the year ended December 31, 2025 are not yet complete. The following information reflects the Company’s preliminary estimates based on currently available information and is subject to change. The Company’s independent registered public accounting firm has not audited, compiled, reviewed or otherwise applied any procedures to the Preliminary Estimated Unaudited Financial Results presented herein and, accordingly, does not express an opinion or any other form of assurance on it***.***

The following table summarizes the results of operations of the Company:

Researchand Development. For the year ended December 31, 2025, the Company expects to report research and development (“R&D”) expense to be between $3.4 million and $3.9 million, as compared to $3.6 million for the year ended December 31, 2024. While the year-over-year change was nominal, the Company anticipates its research and development activities will decrease until such time as it determines the direction of its preclinical and clinical drug development efforts.

Generaland Administrative Expenses. For the year ended December 31, 2025, the Company expects to report general and administrative expenses to be between $5.2 million and $5.8 million, as compared to $1.4 million for the year ended December 31, 2024. The expected increase in general and administrative expenses was primarily due to costs associated with advertising for investor relations of $3.6 million.

Legaland Professional Expenses. For the year ended December 31, 2025, the Company expects to report legal and professional expenses to be between $2.1 million and $2.3 million, as compared to $2.7 million for the year ended December 31, 2024. The expected decrease in legal and professional fees was primarily due to lower expenses related to the Company’s public filing requirements and financing-related work.

OtherIncome (expense). For the year ended December 31, 2025, the Company expects to report total other expense to be between $0.1 million and $0.2 million, as compared to $1.5 million for the year ended December 31, 2024. The expected decrease was primarily driven by a $1.2 million decrease in interest expense and a $0.8 million decrease in the loss on settlement of convertible debt, each resulting from the settlement of the Alto Convertible Note during the year ended December 31, 2024, partially offset by changes in the fair value of convertible notes and derivative liabilities.

BalanceSheet Data:

As of December 31, 2025, the Company expects to report total current assets of approximately $0.5 million and total current liabilities of approximately $1.2 million to $1.3 million, resulting in working capital deficit between $0.7 million and $0.8 million. As of December 31, 2024, total current assets were $2.2 million and total current liabilities were $1.5 million, resulting in a working capital of $0.7 million. The Company expects that the decrease in working capital is primarily attributable to cash paid for the Molecule.ai asset acquisition of $3.0 million, costs incurred in winding down the Company’s clinical trials, and capital preservation while we work to raise additional financing to fund ongoing business and operations.

As of December 31, 2025, the Company expects to report intangible assets, net to be $9.8 million, comprised of the intangible asset acquired in the Molecule.ai asset acquisition. Further, the Company expects contingent consideration and consideration payable to be $2.0 million and $4.4 million, respectively, each representing consideration currently payable or that the Company expects will be payable under the Molecule.ai asset acquisition.

As of December 31, 2025, the Company expects to report other assets of approximately $0.2 million, primarily comprised of the Company’s right-of-use asset for its operating lease. Further, the Company expects the associated operating lease liability to be $0.2 million. The expected decrease in the carrying value of the asset is primarily attributable to an expected impairment during the year ended December 31, 2025 and the expected decrease in the lease liability is attributable to continued rent payments under the lease.

During the year ended December 31, 2025, all notes payable and accrued interest were paid at maturity and all convertible notes that were previously outstanding converted into shares of common stock therefore we expect the associated liabilities to be $0, compared to $0.2 million and $0.7 million, respectively, as of December 31, 2024.
