*<u>Rigel License Agreement</u>*

On May 11, 2026, Arvinas, Inc., a Delaware corporation ("Arvinas"), and Arvinas' direct subsidiaries, Arvinas Operations, Inc. ("Operations") and Arvinas Estrogen Receptor, Inc. ("Arvinas ER," together with Arvinas and Operations, the "Company"), together with Pfizer Inc. ("Pfizer"), entered into a license agreement (the "License Agreement") with Rigel Pharmaceuticals, Inc. ("Rigel"). Pursuant to the License Agreement, the Company and Pfizer will grant to Rigel a license for the exclusive global development, manufacturing and commercialization rights for VEPPANU™ (vepdegestrant), an orally bioavailable PROteolysis TArgeting Chimera (PROTAC), estrogen receptor degrader approved in the U.S. for use as a monotherapy in the treatment of adults with estrogen receptor–positive (ER+), human epidermal growth factor receptor 2–negative (HER2-), ESR1-mutated advanced or metastatic breast cancer, as detected by an FDA-authorized test, with disease progression following at least one line of endocrine therapy.

Under the terms of the License Agreement, Rigel will be responsible for the launch and commercialization of VEPPANU in the U.S. and will own global rights with the ability to sublicense to potential partners to further develop and commercialize VEPPANU outside of the U.S. The Company and Pfizer will be entitled to a percentage of sublicensing revenue generated outside the U.S. The Company and Pfizer will continue to be responsible for current ongoing development activities and Rigel will contribute up to $40.0 million towards these activities.

Under the terms of and as consideration for entering into the License Agreement, Rigel will pay to the Company and Pfizer a one-time, upfront payment in the aggregate amount of $70.0 million. In addition, the Company and Pfizer will receive an additional payment in the amount of $15.0 million from Rigel upon successful completion of select development and manufacturing transition activities. The Company and Pfizer will also be eligible to receive up to an additional $320.0 million as contingent payments based on future development, regulatory and commercial milestones being met, as well as tiered royalties in the mid-teens to mid-20s based upon worldwide net sales of VEPPANU, subject to reduction under certain circumstances as provided in the License Agreement. All payments under the License Agreement will be distributed evenly between the Company and Pfizer. The milestones and royalty payments under the License Agreement replace any unearned future amounts that may be owed by Pfizer to the Company under the collaboration agreement, dated as of July 21, 2021, by and between the Company, certain of the Company's subsidiaries and Pfizer.

Closing of the License Agreement transaction is subject to customary closing conditions, including the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

The License Agreement will become effective upon satisfaction of such closing conditions and will expire on a country-by-country and licensed product-by-licensed product basis until the expiration of the applicable royalty term. The License Agreement contains customary termination provisions, including that Rigel may terminate the License Agreement upon the material breach of the Company and/or Pfizer and the Company and Pfizer may terminate the License Agreement upon the material breach of Rigel. Additionally, Rigel may terminate the License Agreement for convenience subject to a written notice period, following a pre-defined period of time.

The foregoing summary of the License Agreement is not complete and is qualified in its entirety by reference to the full text of the License Agreement, a copy of which the Company expects to file with the U.S. Securities and Exchange Commission as an exhibit to its Quarterly Report on Form 10-Q for the quarter ending June 30, 2026.
