Item 8.01 Other Events.

Pursuant to the terms of the Indenture, dated as of December 17, 2015, between Walgreens Boots Alliance, Inc. (the “Company”) and Wells Fargo Bank, National Association, as trustee (the “trustee”) together with the terms of the applicable notes set forth in an officers’ certificate (collectively, the “indenture”), governing the Company’s $1.25 billion aggregate principal amount of 1.750% notes due 2018, $1.5 billion aggregate principal amount of 2.600% notes due 2021 and $0.75 billion aggregate principal amount of 3.100% notes due 2023 (collectively, the “notes”) issued by the Company on June 1, 2016, the Company is required, because the pending acquisition of Rite Aid Corporation (“Rite Aid”) was not consummated on or before June 1, 2017 (the first anniversary of the issuance of the notes), to redeem all of the notes. Each series of the notes is subject to a special mandatory redemption at a redemption price of 101% of the principal amount thereof, plus accrued and unpaid interest to, but excluding, the date of redemption. Pursuant to the terms of the indenture, the Company provided notice of the special mandatory redemption to the trustee and the holders of the notes on June 2, 2017. The date of redemption will be June 5, 2017.

The Company expects to have sufficient available resources from its cash, investment balances and availability under existing credit facilities and arrangements to consummate the pending acquisition of Rite Aid and, accordingly, does not currently plan to issue additional securities to replace the notes being redeemed. The transaction remains subject to the expiration or termination of applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, approval by the holders of Rite Aid’s common stock and other closing conditions, and there can be no assurance that these conditions to closing will be satisfied.

Such statements include, but are not limited to, statements regarding the expected timing of the closing of the transactions contemplated by the pending merger agreement between the Company and Rite Aid and related financing matters; the ability of the parties to complete the transactions considering the various closing conditions; and the outcome of legal and regulatory matters, including with respect to the outcome of discussions with the Federal Trade Commission and otherwise in connection with the pending acquisition of Rite Aid by the Company.

Such risks include, but are not limited to, risks related to the proposed transactions and acquisitions generally, including the risk that the transactions may not close due to one or more closing conditions to the transactions not being satisfied or waived, such as certain regulatory approvals not being obtained, on a timely basis or otherwise, or that a governmental entity prohibited, delayed or refused to grant approval for the consummation of the transactions or required certain conditions, limitations or restrictions in connection with such approvals, or that the required approval of the amended merger agreement by the stockholders of Rite Aid was not obtained and, accordingly, there can be no assurance that these conditions to closing will be satisfied; the risk that the merger agreement may be terminated in certain circumstances that require a party to pay the other party a termination fee pursuant to the merger agreement; the risk that there may be a material adverse change of Rite Aid or the stores proposed to be sold to Fred’s, Inc. (“Fred’s”) pursuant to that certain Asset Purchase Agreement, dated as of December 19, 2016, by and among Rite Aid, the Company, Fred’s, and AFAE, LLC, or the business of Rite Aid or the stores proposed to be sold to Fred’s may suffer as a result of uncertainty surrounding the transactions; risks related to the ability to realize the anticipated benefits of the proposed transactions; risks associated with the financing of the proposed transactions; the outcome of legal and regulatory matters, including with respect to the outcome of discussions with the FTC and otherwise in connection with the pending acquisition of Rite Aid by the Company; the number of stores divested in connection with such pending acquisition and the terms, timing and consummation of such transactions; the risk of unexpected costs, liabilities or delays, changes in management’s assumptions; the risks associated with the integration of complex businesses; and risks associated with changes in laws, regulations or interpretations thereof. These and other risks, assumptions and uncertainties are described in Item 1A (Risk Factors) of the Company’s Annual Report on Form 10-K for the fiscal year ended August 31, 2016, which is incorporated herein by reference, and in other documents that the Company files or furnishes with the Securities and Exchange Commission.
