| Amendment Description | EXPLANATORY NOTE Sprouts Farmers Market, Inc. (the “Company”) is filing this Amendment No. 1 on Form 10-K/A (the “Amendment”) to amend its Annual Report on Form 10-K for the year ended December 29, 2019 (the “Form 10-K”), which was originally filed with the Securities and Exchange Commission (the “Commission”) on February 20, 2020. Due to a production error, the table in Item 2 of Part I listing our store properties contains information from the prior year. Item 2 of Part I of the Form 10-K is hereby amended to correct the error by the deletion of such table and the introductory text that appeared in the Form 10-K and the addition of the introductory text and table that appear below. No other changes have been made to Item 2 or the remainder of the Form 10-K. This Amendment speaks as of the filing date of the Form 10-K, does not update information in the Form 10-K to reflect events that have occurred subsequent to the filing date of the Form 10-K, and does not modify or update in any way the financial statements or any other disclosures made in the Form 10-K. Except as described above, no other amendments are being made to the Form 10-K. Accordingly, this Amendment should be read in conjunction with the Form 10-K and the Company’s subsequent filings made with the Commission since February 20, 2020. In connection with the filing of this Form 10-K/A, we are including as exhibits currently dated certifications of our chief executive officer and interim chief financial officer. |
