Supplemental Financial Information (Form 8-K)

Supplemental Financial Information

This exhibit provides certain supplemental non-GAAP financial measures for the quarter ended June 30, 2026. As disclosed in the accompanying Current Report on Form 8-K, Organon & Co. (the "Company") is furnishing this information in lieu of including such supplemental measures in a quarterly earnings release. As referenced below, the Company believes that these supplemental measures assist in understanding its financial performance, but that such measures should not be considered as a substitute for the Company's financial results prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). Accordingly, these supplemental measures are intended by the Company to accompany, and should be considered together with, the Company's GAAP financial results and disclosures referenced in this Exhibit, as well as contained in the Company's Quarterly Report on Form 10-Q for the quarter ended June 30, 2026 that has been filed with the Securities and Exchange Commission on July 31, 2026.
