Amendment Description	We are filing this Amendment No. 2 to Annual Report on Form 10-K/A (this “Amended Form 10-K”) to amend our Annual Report on Form 10-K for the fiscal year ended December 30, 2023, as originally filed with the Securities and Exchange Commission (the “SEC”) on March 29, 2024 (the “Original Form 10-K”), to include the information required by Items 10 through 14 of Part III of Form 10-K. This information was previously omitted from the Original Form 10-K in reliance on General Instruction G(3) to Form 10-K, which permits the information in Part III to be incorporated by reference in the Form 10-K from our definitive proxy statement if such statement is filed no later than 120 days after our fiscal year-end. We are filing this Amended Form 10-K to include the Part III information in our Form 10-K because we do not intend to file a definitive proxy statement within 120 days of December 30, 2023. The reference on the cover of the Original Form 10-K to the incorporation by reference to portions of our definitive proxy statement into Part III of the Original Form 10-K is hereby deleted. In accordance with Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Part III, Items 10 through 14 of Part III of the Original Form 10-K are hereby amended and restated in their entirety, and Part IV, Item 15 of the Original Form 10-K is hereby amended and restated in its entirety. This Amended Form 10-K does not amend or otherwise update any other information in the Original Form 10-K. Accordingly, this Amended Form 10-K should be read in conjunction with the Original Form 10-K, Amendment No. 1 to Annual Report on Form 10-K/A filed with the SEC on April 1, 2024 and with our subsequent filings with the SEC. All capitalized terms used but not defined herein shall have the meanings ascribed to them in the Original Form 10-K.
