On March 13, 2024, Artal International S.C.A. purchased 1,150,922 shares of Series A Convertible Preferred Stock (the “Preferred Stock”) of the Issuer for an aggregate purchase price of $124,875,037 representing a purchase price of $108.50 per share.

Item 4. Purpose of Transaction

Item 4 of the Statement is hereby amended and supplemented to include the following:

The information set forth in Items 3 and 6 of the Statement is incorporated herein by reference.

On March 11, 2024, the Issuer entered into a Preferred Stock Purchase Agreement (the “Purchase Agreement”) with certain accredited investors (the “Purchasers”). Pursuant to the Purchase Agreement, the Issuer agreed to sell 2,304,147 shares of Preferred Stock at a price per share of $108.50 in a private placement (the “Private Placement”). Each share of Preferred Stock will automatically convert into 50 shares (subject to adjustments) of Issuer Common Stock immediately following the satisfaction of all of the following conditions: (i) the approval of the Sixth Amended and Restated Certificate of Incorporation of the Issuer (the “New Charter”) by the shareholders of the Issuer at the 2024 annual meeting of stockholders (the “Annual Meeting”); (ii) the adoption of the New Charter by the Issuer’s board of directors; and (iii) the filing and acceptance of the New Charter with and by the Secretary of State of the State of Delaware. The holders of the Preferred Stock are entitled to vote on an as-converted basis on all matters and not as a separate class vote, except as required by Delaware law. The closing of the Private Placement occurred on March 13, 2024.

The Purchase Agreement also contains customary registration rights whereby the Issuer has agreed to file a registration statement with the U.S. Securities and Exchange Commission (the “SEC”), concurrently with or within 10 business days after filing the preliminary proxy statement for the Annual Meeting, thereby registering the resale of the shares of Common Stock issuable upon the conversion of the shares of Preferred Stock issued in the Private Placement.

Artal International S.C.A., one of the Purchasers under the Purchase Agreement, elected to participate in the Private Placement on the same terms as each other Purchaser pursuant to its preemptive right under the Issuer’s Fifth Amended and Restated Certificate of Incorporation to participate in new issuances of the Issuer’s equity securities on a pro rata basis. Pursuant to a Voting Support Agreement, dated March 11, 2024 (the “Support Agreement”), the Invus Parties have agreed to, among other things, vote their shares at the Annual Meeting in favor of the approval of the New Charter and have agreed not to transfer their voting securities (except to affiliates) until the New Charter is approved.

The Purchase Agreement contains customary representations, warranties and agreements by the Issuer and customary conditions to closing, obligations of the parties and termination provisions. The above description of the Purchase Agreement and Support Agreement is qualified in its entirety by reference to the Purchase Agreement and Support Agreement, which are filed as exhibits to this Statement and incorporated herein by reference.
