Dear Shareholder:

We previously sent to you proxy materials for the Annual General Meeting of Shareholders (“AGM”) and the Extraordinary General Meeting of Shareholders (“EGM”) of Mylan N.V., each to be held on June 30, 2020. Your Board of Directors unanimously recommends that shareholders vote FOR all items on the AGM and EGM agendas.

Your vote is important, no matter how many shares you may own. Since the AGM and EGM voting deadlines are fast approaching, we encourage you to vote TODAY by telephone or via the Internet, to ensure that your shares are represented. You may also sign, date and return the enclosed single proxy card in the postage-paid envelope provided.

Thank you for your support.

Very truly yours,

Joseph F. Haggerty

Corporate Secretary
