Recently you received proxy materials for the upcoming Annual Meeting of Stockholders of Walgreens Boots Alliance, Inc. (the “Company”) to be held May 28, 2015. It has come to our attention that, due to our inadvertent clerical error, the materials you received contained a proxy card that included an incorrect telephone number to be called to vote by telephone, one of the three ways presented to vote your shares. The correct telephone number to vote by telephone is 1-800-690-6903. This telephone number is correctly reflected on the proxy card included in this envelope. No other changes have been made to the proxy card. This clerical error affected the proxy card distributed to holders of, in the aggregate, less than 1% of the Company’s outstanding shares.

If you have not already voted, you may vote your shares by following the instructions on the enclosed proxy card. If you have already submitted a proxy card or voted by telephone or the Internet, you do not need to vote again unless you wish to change your vote. You may change your vote at any time prior to the Annual Meeting. See “Can I change my vote after I return the proxy card, or after voting by telephone or electronically?” under “Questions and Answers about the Proxy Materials and the Annual Meeting” on page 7 of the Proxy Statement the Company filed with the Securities and Exchange Commission and first distributed to stockholders on or about April 17, 2015. The Proxy Statement contains important information that should be read before voting.

Please note that Broadridge Financial Solutions, Inc., not the Company, will bear the cost of this additional mailing to the affected stockholders. We apologize for any inconvenience this may have caused you.
