* This calculation is based on 205,632,943 shares of Common Stock outstanding as of October 31, 2015 (as reported by the Issuer in its Annual Report on Form 10-K for the fiscal year ended September 30, 2015 filed with the SEC on November 24, 2015), plus 22,696,912 shares of Common Stock issuable upon the exercise of warrants (Warrant 1) that may be deemed to be beneficially owned by the Reporting Person that are exercisable within 60 days of the date of this Amendment No. 2, which shares are deemed to be outstanding for the purpose of computing the percentage of outstanding shares beneficially owned by the Reporting Person in accordance with Exchange Act Rule 13d-3(d)(1)(i).

This Amendment No. 2 to Schedule 13D (this “Amendment No. 2”) amends and supplements the Schedule 13D (the “Schedule 13D”) relating to the common stock, $0.01 par value per share (“Common Stock”), of AmerisourceBergen Corporation, a Delaware corporation (the “Issuer”), originally filed with the Securities and Exchange Commission (the “SEC”) on April 9, 2014, as amended by Amendment No. 1 thereto filed with the SEC on January 16, 2015. Terms used but not defined in this Amendment No. 2 have the respective meanings given to such terms in the original Schedule 13D, as amended by Amendment No. 1 thereto.

Explanatory Note

This Amendment No. 2 is being filed because, pursuant to Rule 13d-3(d) under the Exchange Act, shares underlying warrants that become exercisable within 60 days are deemed beneficially owned for purposes of Section 13(d) of the Exchange Act and, as previously disclosed in the Schedule 13D, Warrant 1 will by its terms become exercisable in March 2016. Accordingly, pursuant to Rule 13d-3(d) under the Exchange Act, certain of the Reporting Persons may, as disclosed herein, be deemed to be the beneficial owner of the shares of Common Stock underlying Warrant 1 (in addition to their previously-reported beneficial ownership) as of the filing of this Amendment No. 2. This Amendment No. 2 also reflects the completion of an internal reorganization of certain subsidiaries of Walgreens Boots Alliance, Inc., a Delaware corporation (“WBA”), and the transfer of certain securities of the Issuer between wholly-owned subsidiaries of WBA in accordance with the Framework Agreement and related agreements.

Item 2. Identity and Background.

During the last five years, each Reporting Person and, to the knowledge of such Reporting Person, each person listed in Annex A with respect to such Reporting Person, has not been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors) and has not been a party to a civil proceeding of any judicial or administrative body of competent jurisdiction as a result of which such person was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding of any violation with respect to such laws.

Item 5. Interest in Securities of the Issuer

Item 5 is hereby amended by adding the following:

(a) and (b). The ownership percentages set forth below are based on 205,632,943 shares of Common Stock outstanding as of October 31, 2015, as reported by the Issuer on its Annual Report on Form 10-K for the fiscal year ended September 30, 2015, filed by the Issuer with the SEC on November 24, 2015, plus, where applicable, the number of shares of Common Stock issuable upon the exercise of warrants that may be deemed to be beneficially owned by certain of the Reporting Persons that are exercisable within 60 days of the date of this Amendment No. 2, which shares are deemed to be outstanding for the purpose of computing the percentage of outstanding shares beneficially owned by the Reporting Person in accordance with Exchange Act Rule 13d-3(d)(1)(i).

WBA Holdings may be deemed to beneficially own 11,461,043 outstanding shares of Common Stock. In addition, WBA Holdings is the holder of Warrant 1, which, as previously disclosed in the Schedule 13D, will by its terms become exercisable in March 2016. Therefore, pursuant to Rule 13d-3(d) under the Exchange Act, the 22,696,912 shares of Common Stock underlying Warrant 1 may be deemed to be beneficially owned by WBA Holdings as of the filing of this Amendment No. 2. As a result, WBA Holdings may be deemed to beneficially own an aggregate of 34,157,955 shares of Common Stock (representing approximately 14.96% of the total number of shares of Common Stock outstanding, assuming the exercise in full of Warrant 1) as of the filing of this Amendment No. 2.

By virtue of relationships reported in Item 2, each of WPS, Bond Drug, WEC, WADC, WHC, Walgreen and WBA may be deemed to share the power to vote or direct to vote or to direct the voting of, and to dispose of or to direct the disposition of and, accordingly, may be deemed to beneficially own the 11,461,043 outstanding shares of Common Stock held by WBA Holdings and the 22,696,912 shares of Common Stock underlying Warrant 1 held by WBA Holdings. As a result of the foregoing, each of WPS, Bond Drug, WEC, WADC, WHC, Walgreen and WBA may be deemed to beneficially own an aggregate of 34,157,955 shares of Common Stock (representing approximately 14.96% of the total number of shares of Common Stock outstanding, assuming the exercise in full of Warrant 1) as of the filing of this Amendment No. 2.

As a result of the completion of the internal reorganization, each of AB Luxembourg, AB Holdings, AB UK Holdco, Superior Acquisitions, AB International, AB Limited, AB UK Topco, AB Luxco 1, Alliance Boots, Walgreen Swiss, Superior, Walgreen International, Superior Bermuda, Superior Luxco 3, WBA Scottish, WBA Scottish 1, Superior Luxco 2, Superior Luxco 1, Walgreen Investments Lux, Walgreen International Investments, WBA Investments and WIC no longer beneficially own any shares of Common Stock of the Issuer as of the filing of this Amendment No. 2.

Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by any Reporting Person (other than WBA Holdings) that it is the beneficial owner of any shares of Common Stock for purposes of Section 13(d) of the Exchange Act, or for any other purpose, and such beneficial ownership is expressly disclaimed.

(c), (d) and (e). The information set forth in the third paragraph of Item 2 of this Amendment No. 2 is incorporated herein by reference. With respect to each Reporting Person, such Reporting Person and, to the knowledge of such Reporting Person, the persons listed in Annex A hereto with respect to such Reporting Person, have not otherwise effected any transaction in shares of Common Stock in the past 60 days.

Other than WBA Holdings, WPS, Bond Drug, WEC, WADC, WHC, Walgreen and WBA and the persons listed in Annex A hereto with respect thereto, no other person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of the shares of Common Stock covered by this Schedule 13D.
