Item 8.01

Other Events.

As previously disclosed, on March 12, 2023, Seagen Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among the Company, Pfizer Inc., a Delaware corporation (“Pfizer”) and Aris Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Pfizer (“Merger Sub”). Pursuant to the Merger Agreement, Merger Sub will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly-owned subsidiary of Pfizer.

Also, as previously disclosed, on May 12, 2023, the Company and Pfizer each filed with the Federal Trade Commission (“FTC”) and Department of Justice (“DOJ”) a Notification and Report Form relating to the Merger Agreement and the Merger as required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”).

As agreed with the Company, Pfizer withdrew its Notification and Report Form and will refile that form today, June 14, 2023. Accordingly, the statutory waiting period under the HSR Act will be scheduled to expire at 11:59pm ET on July 14, 2023. This statutory waiting period may be extended if the FTC issues a request for additional information and documentary material.

Additionally, on June 1, 2023, the Company and Pfizer referred the Merger to the European Commission (the “EC”) for review under Article 4(5) of the EU Merger Regulation. If the EC obtains jurisdiction to review the Merger as a result of such referral, receipt of approval from the EC for the Merger would become a condition for the closing of the Merger.

As previously disclosed, the Company continues to expect that the Merger will be completed in late 2023 or early 2024, subject to fulfillment of customary closing conditions, including receipt of required regulatory approvals.
