Organon & Co.

Item 7.01. Regulation FD Disclosure. On July 31, 2026, Organon & Co. (the “Company”) released its financial results for the quarter ended June 30, 2026 with the filing of the Company’s Quarterly Report on Form 10-Q (the “Form 10-Q”) with the Securities and Exchange Commission (the “SEC”). As previously disclosed, in light of the Company’s pending merger with Sun Pharmaceutical Industries Limited, the Company has suspended its customary practice of issuing a quarterly earnings press release and hosting an earnings conference call. As part of the information provided in historic Company earnings press releases, the Company would furnish, together with its U.S. generally accepted accounting principles (“GAAP”) financial information for the reported quarterly period, certain supplemental non-GAAP financial metrics for the same reported period. These supplemental measures have been made available by the Company based on the belief that this information assists in understanding the Company’s financial performance, but not as a substitute for the Company’s financial results under GAAP. To continue this practice, the Company is furnishing certain supplemental non-GAAP metrics for the quarter ended June 30, 2026 that are included in Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference. The non-GAAP financial metrics for the quarter ended June 30, 2026 that are furnished in this Form 8-K should be read together with the Company’s GAAP financial statements and other disclosures that are contained in Exhibit 99.1 and that are more fully disclosed in the Form 10-Q filed with the SEC on July 31, 2026. The information contained in this Item 7.01, including Exhibit 99.1 attached hereto, is considered to be “furnished” and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to liability under that Section. The information in this Current Report shall not be incorporated by reference into any filing or other document pursuant to the Securities Act of 1933, as amended (the “Securities Act”) or the Exchange Act, except as shall be expressly set forth by specific reference in such filing or document. The Current Report on Form 8-K, including Exhibit 99.1, contains forward-looking statements regarding the Company and includes a cautionary statement identifying important factors that could cause actual results to differ materially from those anticipated.
