Summary

Organon filed supplemental merger proxy disclosures in response to a shareholder lawsuit filed July 6, 2026 in New Jersey Superior Court. The plaintiff alleges the original proxy statement omitted material information and filed a motion July 13 seeking to enjoin the July 23 special meeting vote on the Sun Pharma acquisition.

While Organon denies the claims, the company is voluntarily supplementing the proxy to avoid potential delays and litigation costs as the shareholder vote approaches. The supplemental disclosures provide additional context around the merger negotiations and Board deliberations. Organon presented preliminary cost synergy estimates of approximately $700 million to Sun Pharma during January 2026 diligence meetings.

The Board also evaluated a complex alternative strategy involving a merger of equals followed by divestitures and multiple acquisitions, but determined the execution risks were significant. The filing also clarifies certain financial advisor methodologies and provides updated financial metrics including fully diluted shares of approximately 284.9 million and net debt of $7,530 million as of March 31, 2026. These are procedural supplements to existing merger disclosures rather than material changes to the transaction terms or timeline.

Morgan Stanley observed additional factors that were not considered as part of Morgan Stanley’s financial analyses with respect to its opinion, but which were noted as reference data for the Board, including the following information described in the sections entitled “—Publicly Traded Companies Analysis,” “—Precedent Transactions Analysis,” “—Premia Paid Analysis,” “—Analysts’ Price Targets,” and “—Historical Trading Range.” These additional factors were provided as supplemental reference data to assist the Board in connection with its evaluation of the Merger. Such additional factors were not considered as part of Morgan Stanley’s financial analyses with respect to its opinion because the material financial analyses performed by Morgan Stanley in connection with its oral opinion and the preparation of its written opinion letter were deemed by Morgan Stanley, in its professional judgment, to provide a sufficient basis for rendering its opinion.

Morgan Stanley clarified that certain analyses in the proxy were reference data for the Board but not part of the formal fairness opinion. The financial advisor deemed its core analyses sufficient for rendering its opinion without incorporating the supplemental reference data.
