Explanatory Note

This Current Report on Form 8-K/A is being filed as an amendment (“Amendment No. 1”) to the Current Report on Form 8-K filed by Sprouts Farmers Market, Inc. (the “Company”) with the Securities and Exchange Commission on May 16, 2014 (the “Original Form 8-K”). This Amendment No. 1 updates “Item 5.07 - Submission of Matters to a Vote of Security Holders” in the Original Form 8-K to disclose the decision of the Company’s Board of Directors (the “Board”) regarding how frequently the Company will conduct future non-binding advisory votes on the compensation paid to its named executive officers. No other changes have been made to the Original Form 8-K.

Item 5.07. Submission of Matters to a Vote of Security Holders.

As previously reported in the Original Form 8-K, at the Company’s May 15, 2014 annual meeting of stockholders (the “Annual Meeting”), a non-binding, advisory vote was conducted concerning the frequency of the vote regarding the compensation paid to the Company’s named executive officers. In the Company’s proxy statement furnished to stockholders in connection with the Annual Meeting, the Board recommended a vote for every year. At the Annual Meeting, “one year” received the greatest number of votes. After considering the preferences expressed at the Annual Meeting, the Board has determined to hold future non-binding, advisory votes on the compensation paid to its named executive officers every year, so that the next such vote will be held at its 2015 annual meeting of stockholders. Under Section 14A(a)(2) of the Securities Exchange Act of 1934, as amended, the Company will hold another vote on the frequency of the vote regarding the compensation paid to its named executive officers no later than its 2020 annual meeting of stockholders.
