Item 1.01. Entry into a Material Definitive Agreement.

On October 1, 2019, Progenics Pharmaceuticals, Inc. (“Progenics”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Lantheus Holdings, Inc. (“Lantheus Holdings”) and Plato Merger Sub, Inc., a wholly owned subsidiary of Lantheus Holdings (“Merger Sub”). The Merger Agreement provides, among other things, that on the terms and subject to the conditions set forth therein, Merger Sub will merge with and into Progenics, with Progenics surviving as a wholly-owned subsidiary of Lantheus Holdings (the “Merger”).

In the Merger, each share of Progenics common stock issued and outstanding immediately prior to the effective time of the Merger (other than certain excluded shares as described in the Merger Agreement) will automatically be converted into the right to receive 0.2502 of a share of Lantheus Holdings common stock (the “Exchange Ratio”). In addition, upon the closing of the Merger, all Progenics stock options, whether vested or unvested, will be assumed by Lantheus Holdings and converted into options to purchase Lantheus Holdings shares of common stock. The number of shares subject to the assumed stock options and the exercise price of such stock options will be adjusted upon the closing of the Merger based on the Exchange Ratio. Such options will otherwise have the same vesting and other terms as applied to the Progenics stock options prior to the closing.

At the effective time of the Merger, the board of directors of Lantheus Holdings (the “Lantheus Board”) will appoint one member who is (i) a member of the board of directors of Progenics as of the date of the Merger Agreement, (ii) mutually agreed to by Progenics and Lantheus Holdings, acting in good faith, and (iii) reasonably approved by the Nominating and Corporate Governance Committee of the Lantheus Board.

Completion of the Merger is subject to customary closing conditions, including (among others) (1) the adoption of the Merger Agreement by a majority of the holders of the outstanding shares of Progenics common stock, (2) approval of the issuance of Lantheus Holdings common stock issued in the Merger by a majority of the votes cast by Lantheus Holdings stockholders on the matter, (3) approval for listing on the Nasdaq Global Market of Lantheus Holdings common stock, (4) the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (5) accuracy of the other party’s representations and warranties, subject to certain materiality standards set forth in the Merger Agreement, (6) compliance in all material respects with the other party’s obligations under the Merger Agreement and (7) the absence of a material adverse effect on Progenics.

Either Progenics or Lantheus Holdings may terminate the Merger Agreement in certain circumstances, including if (1) the Merger is not completed by July 1, 2020, (2) Progenics’ stockholders fail to adopt the Merger Agreement, (3) Lantheus Holdings’ stockholders fail to approve the share issuance in connection with the Merger, (4) a governmental authority of competent jurisdiction has issued a final non-appealable governmental order prohibiting the Merger, (5) the other party breaches its representations, warranties or covenants in the Merger Agreement in a way that would entitle the party seeking to terminate the Merger Agreement not to consummate the Merger, subject to the right of the breaching party to cure the breach, (6) the other party’s board of directors has changed its recommendation in favor of the Merger or (7) the other party willfully and materially breaches certain covenants contained in the Merger Agreement. In the event of a termination of the Merger Agreement under certain specified circumstances, including a termination by Lantheus Holdings following a change in recommendation by Progenics’ board of directors or a willful and material breach of the no-solicitation provision applicable to Progenics, Progenics may be required to pay Lantheus Holdings a termination fee equal to $18,340,000 (the “Company Termination Fee”). In the event of a termination of the Merger Agreement under certain specified circumstances, including a termination by Progenics following a change in recommendation by Lantheus Holdings’ board of directors or a willful and material breach of the no-solicitation provision applicable to Lantheus Holdings, Lantheus Holdings may be required to pay Progenics a termination fee equal to $18,340,000. In the event of a termination of the Merger Agreement as a result of Progenics stockholders failing to adopt the Merger Agreement, Progenics may be required to reimburse the reasonable and documented out-of-pocket expenses incurred by Parent and its subsidiaries in connection with the Merger Agreement not to exceed $5,240,000.

If Progenics willfully and materially breaches the Merger Agreement and the Merger Agreement is thereafter terminated, Progenics may be required to pay damages to Lantheus Holdings equal to $18,340,000, net of any previously paid expense reimbursement paid to Lantheus Holdings by Progenics, unless Progenics has previously paid the Company Termination Fee.

The foregoing description of the Merger and the Merger Agreement is not complete and is qualified in its entirety by the full text of the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1 and the terms of which are incorporated herein by reference.

Important Statement Regarding the Merger Agreement

The Merger Agreement has been included to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about Lantheus Holdings, Merger Sub, Progenics or their respective subsidiaries and affiliates. The Merger Agreement contains representations and warranties by Lantheus Holdings and Merger Sub, on the one hand, and by Progenics, on the other hand, made solely for the benefit of the other. The assertions embodied in those representations and warranties are qualified by information in confidential disclosure schedules delivered by each party in connection with the signing of the Merger Agreement. Moreover, certain representations and warranties in the Merger Agreement were made as of a specified date, may be subject to a contractual standard of materiality different from what might be viewed as material to stockholders or may have been used for the purpose of allocating risk between Lantheus Holdings and Merger Sub, on the one hand, and Progenics, on the other hand. Accordingly, the representations and warranties in the Merger Agreement are not necessarily characterizations of the actual state of facts about Lantheus Holdings or Progenics at the time they were made or otherwise. In addition, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Lantheus Holdings’ or Progenics’ public disclosures. The Merger Agreement should not be read alone but should instead be read in conjunction with the other information regarding the Merger Agreement, the Merger, Lantheus Holdings, Progenics, their respective affiliates and their respective businesses, that will be contained in, or incorporated by reference into, the Registration Statement on Form S-4 that will include a joint proxy statement of Progenics and Lantheus Holdings and a prospectus of Lantheus Holdings, as well as in the Forms 10-K, Forms 10-Q and other filings that each of Lantheus Holdings and Progenics make with the Securities and Exchange Commission (“SEC”).

Item 5.03. Amendments to Articles of incorporation or Bylaws; Change in Fiscal Year.

On October 1, 2019, Progenics’ board of directors approved an amendment to Progenics’ By-laws (the “Bylaw Amendment”). The Bylaw Amendment became effective on October 1, 2019.

The Bylaw Amendment provides that, among other things, unless the Progenics consents in writing to the selection of an alternative forum, the Court of Chancery in the State of Delaware will, to the fullest extent permitted by law, be the sole and exclusive forum for (1) any derivative action or proceeding brought on behalf of the Progenics, (2) any action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, other employee or stockholder of Progenics to Progenics or Progenics’ stockholders, (3) any action asserting a claim arising pursuant to any provision of the General Corporation Law of the State of Delaware, the Certificate of Incorporation or these Bylaws or as to which the General Corporation Law of the State of Delaware confers jurisdiction on the Court of Chancery of the State of Delaware, or (4) any action asserting a claim arising out of or relating to Progenics’ the internal affairs.

The foregoing description of the Bylaw Amendment does not purport to be complete and is qualified in its entirety by reference to the Bylaw Amendment, which is filed as Exhibit 3.2 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 8.01. Other Events.

On October 2, 2019, Lantheus Holdings and Progenics issued a joint press release announcing the execution of the Merger Agreement as described above. A copy of the press release is attached as Exhibit 99.1 and incorporated herein by reference.
