Organon & Co.

Our management, with the participation of our Chief Executive Officer (“CEO”) (our principal executive officer) and Chief Financial Officer (“CFO”) (our principal financial officer), evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act of 1934, as amended (the “Exchange Act”)) as of September 30, 2026. Based upon that evaluation, our CEO and our CFO concluded that, as of September 30, 2026, the end of the period covered by this report, our disclosure controls and procedures were effective and provide reasonable assurance that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our CEO and our CFO, as appropriate, to allow timely decisions regarding required disclosure.

During the quarter ended September 30, 2026, there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
