On November 16, 2020, Mylan N.V. (“Mylan”) completed the transaction pursuant to which Mylan combined with Pfizer Inc.’s (“Pfizer”) Upjohn business (the “Upjohn Business”) in a Reverse Morris Trust transaction (the “Combination”) and Upjohn Inc. (“Upjohn”) became the parent entity of the combined Upjohn Business and Mylan business and was renamed “Viatris Inc.” (“Viatris”). Pursuant to the terms of the Business Combination Agreement (as amended), dated July 29, 2019, by and among Mylan, Pfizer, Upjohn and certain other affiliated entities, Upjohn and Mylan effected the Combination through a series of transactions, including that Mylan merged with and into Mylan II B.V. surviving the merger as the legal successor of Mylan.

On November 16, 2020, The Nasdaq Stock Market filed a Form 25 to remove Mylan II B.V.’s ordinary shares, nominal value €0.01, from listing and registration pursuant to 17 CFR 240.12d-2-2(a)(3).

Pursuant to the Combination Mylan II B.V. has become a wholly owned subsidiary of Viatris Inc. and, as such, has fewer than 300 record holders. Therefore, Mylan II B.V.’s Section 15(d) reporting obligation for its ordinary shares, nominal value €0.01, has been suspended pursuant to Rule 12g-4(a)(1) and Rule 12h-3(b)(1)(i).

Pursuant to the requirements of the Securities Exchange Act of 1934 Mylan II B.V. has caused this certification/notice to be signed on its behalf by the undersigned duly authorized person.
