[8-K] Organon & Co. Reports Material Event

Filing Explained

Proxy disclosures are supplemented before the July 23 vote; the merger remains pending and would make Organon Sun Pharma’s wholly owned subsidiary if completed.

Organon is providing supplemental merger-proxy disclosures while its proposed merger with Sun Pharma remains subject to the July 23, 2026 stockholder vote and an unresolved injunction motion; if completed, Organon would become Sun Pharma’s wholly owned subsidiary.

A Form 8-K reports a material event, while a proxy statement presents matters for stockholder vote; this filing adds information to the definitive proxy without reporting that the merger has closed or that the vote has occurred.

The added information includes a preliminary estimate of approximately $700 million of aggregate potential synergies, unaudited projections through 2030, approximately $284.9 million fully diluted shares as of April 24, 2026, and net debt of $7.530 billion as of March 31, 2026.

A complaint was filed on July 6, 2026, and a motion filed on July 13, 2026 seeks to delay the meeting and require further proxy disclosure; the court had not ruled as of July 17, 2026, while Organon denies the allegations and is supplementing the proxy without admitting liability.

This filing does not state the merger consideration or how existing common shares would be treated, so it establishes the proposed ownership transition but not the economic terms for current holders.

The specified near-term milestones are the court’s ruling on the injunction motion and the scheduled July 23, 2026 special meeting.

Item 8.01 Other Events.

As previously disclosed, on April 26, 2026, Organon & Co., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among the Company, Sun Pharmaceutical Holdings USA, Inc. (“Sun Pharma USA”), and Sun Pharma America, Inc., a wholly owned subsidiary of Sun Pharma USA (“Merger Sub”), and, solely for purposes of certain specified provisions of the Merger Agreement, Sun Pharmaceutical Industries Limited, Sun Pharma Canada Inc. and Sun Pharma (Netherlands) B.V., pursuant to which Merger Sub will be merged with and into the Company, with the Company surviving the merger as a wholly owned subsidiary of Sun Pharma USA (the “Merger”). On June 17, 2026, in connection with the Merger, the Company filed with the Securities and Exchange Commission (“SEC”) a definitive proxy statement (as supplemented, the “Definitive Proxy Statement”) with respect to the special meeting of the Company’s stockholders (“Special Meeting”) scheduled to be held on July 23, 2026. Additional information about how to attend the Special Meeting is contained in the Definitive Proxy Statement.

Litigation Relating to the Merger

On July 6, 2026, a complaint was filed in connection with the Merger in the Superior Court of New Jersey, County of Mercer Chancery Division, against the Company, the current members of the board of directors (the “Board”) of the Company, Sun Pharma USA and Merger Sub (collectively, the “Defendants”). The action is captioned Richard Delman v. Robert Essner, et al., No. MER-C-000047-26 (July 6, 2026) (the “Complaint”).

The Complaint alleges, among other things, that certain disclosures in the Definitive Proxy Statement filed by the Company in connection with the Merger were materially incomplete and misleading. The Complaint further alleges violations of the New Jersey Uniform Securities Law, N.J. Stat. § 49:3-71, and, under New Jersey common law, negligent misrepresentation and concealment, general negligence, and civil conspiracy.

The Complaint seeks declaratory and injunctive relief, including enjoining the Defendants from proceeding with the stockholder vote on the Merger unless and until the Company issues a supplemental proxy statement that fully discloses the allegedly omitted material information. The Complaint also seeks an award of attorneys’ and expert fees and expenses. On July 13, 2026, the Plaintiff filed a motion seeking to enjoin preliminarily the holding of our Special Meeting and to require the Company to supplement the Definitive Proxy Statement in certain respects. The court has not ruled on this motion.

The Company believes that the claims and allegations in the Complaint and the assertions in the pending injunction motion are without merit and that no further disclosure is required under applicable law. However, to avoid the risk of the claims delaying or adversely affecting the Merger and to minimize the costs, risks, and uncertainties inherent in litigation, and without admitting any liability or wrongdoing, the Company has determined to voluntarily supplement the Definitive Proxy Statement as described in this Current Report on Form 8-K. Nothing in this Current Report on Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, the Company specifically denies

all allegations in the Complaint and any assertion that additional disclosure was or is required. As of July 17, 2026, the Company was not aware of the filing of other lawsuits challenging the Merger or the Definitive Proxy Statement; however, additional lawsuits arising out of the Merger or the Definitive Proxy Statement may be filed in the future.

Supplemental Disclosures to Definitive Proxy Statement

This supplemental information to the Definitive Proxy Statement should be read in conjunction with the Definitive Proxy Statement, which should be read in its entirety. All page references in the information below are to pages in the Definitive Proxy Statement, and all terms used but not defined below shall have the meanings set forth in the Definitive Proxy Statement. Except as specifically noted herein, the information set forth in the Definitive Proxy Statement remains unchanged.

The disclosure in the section of the Definitive Proxy Statement entitled “The Merger (Proposal 1)—Background of the Merger” is hereby amended and supplemented by adding the following underlined language to the fourth paragraph on page 46 of the Definitive Proxy Statement.

Throughout January, Sun Pharma conducted preliminary diligence and participated in virtual management meetings with Organon. On January 22, 2026, Organon presented potential synergies across a range of business segments to Sun Pharma and identified potential cost synergies across commercial, procurement, R&D and corporate functions, which were preliminarily estimated to be approximately $700 million in the aggregate.

The disclosure in the section of the Definitive Proxy Statement entitled “The Merger (Proposal 1)—Background of the Merger” is hereby amended and supplemented by adding the following underlined language to the last paragraph on page 46 of the Definitive Proxy Statement.

On February 3, 2026, the Board met with representatives of Organon management, S&C, and Morgan Stanley to discuss the January 29 Sun Pharma IOI. At the meeting, a representative of Morgan Stanley updated the Board on recent communications with Sun Pharma, as well as the anticipated timing and next steps in the process for a potential transaction, and reviewed with the Board the updated preliminary financial analyses. The Board also discussed potential synergies from a transaction with Sun Pharma, including the preliminary synergy estimates previously presented to Sun Pharma. The Board then discussed valuation methodologies, synergy analyses, and a set of select companies for potential outreach, along with related recommendations. Following this discussion, the Board determined its strategy for responding to Sun Pharma and agreed that Ms. Cox should convey to Mr. Shanghvi that the Board was not prepared to pursue a transaction at a price of $13.50 per share of Common Stock and that the Board was evaluating a range of other alternatives and had not determined to sell Organon at this time absent receipt of a price it deemed compelling. At that same meeting, a representative of Goldman Sachs presented to the Board regarding sequential transactions involving (i) a merger of equals with an integrated specialty pharmaceutical company, followed by (ii) a divestiture of Established Brands and generics business of the combined company, (iii) acquisitions of innovative pipeline products and (iv) strategic investments in dermatology and women’s health as well as continued development

of Organon’s pipeline products. During the presentation, the Board raised various issues regarding the specific companies evaluated, the geographic scope, the execution risks, the sensitivity of the analysis to Organon’s key product performance and the contemplated transaction structures. Following the presentation and the Board’s discussion of these strategic alternatives, the Board continued to evaluate a range of strategic alternatives, including focusing on Sun Pharma’s proposal. In doing so, the Board considered the significant execution risks associated with the Goldman Sachs strategic alternatives, including the need to identify suitable counterparties for multiple future transactions and successfully execute a series of acquisitions, integrations and other strategic initiatives.

The disclosure in the section of the Definitive Proxy Statement entitled “The Merger (Proposal 1)—Opinion of Morgan Stanley & Co. LLC—Other Information” is hereby amended and supplemented by adding the following underlined language to the last paragraph on page 59 of the Definitive Proxy Statement.

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.

The disclosure in the section of the Definitive Proxy Statement entitled “The Merger (Proposal 1)—Certain Unaudited Financial Information” is hereby amended and supplemented by adding the following underlined language on page 64 of the Definitive Proxy Statement.
