Amendment Description United States Cellular Corporation (UScellular) filed its Annual Report on Form 10-K for the year ended December 31, 2024 on February 21, 2025 (Original Form 10-K). General Instruction G. (3) of Form 10-K provides that the information required by Part III (Items 10 through 14) may be incorporated by reference from the registrant's definitive proxy statement (filed or required to be filed pursuant to Regulation 14A), which involves the election of directors, if such definitive proxy statement is filed with the Securities and Exchange Commission (SEC) no later than 120 days after the end of the fiscal year covered by the Form 10-K. However, General Instruction G. (3) of Form 10-K also provides that the Items comprising the Part III information may be filed as part of the Form 10-K, or as an amendment to the Form 10-K and, in such case, must be filed no later than the end of such 120-day period. In UScellular’s Original Form 10-K, UScellular had disclosed that it intended to incorporate such information from its Notice of Annual Meeting of Shareholders and Proxy Statement (Proxy Statement) for the 2025 Annual Meeting of Shareholders. However, UScellular has instead determined to file the information required by Part III, Items 10 through 14 in this Amendment No. 1 to UScellular's 2024 Form 10-K. Accordingly, this Amendment No. 1 is being filed for the sole purpose of filing the information required by Part III, Items 10 through 14. Other than the items outlined above, UScellular has not modified or updated disclosures presented in the Original Form 10-K in this Form 10-K/A. Accordingly, this Form 10-K/A does not modify or update the disclosures in the Original Form 10-K to reflect subsequent events, results or developments or facts that have become known after the date of the Original Form 10-K. Therefore, this Form 10-K/A should be read in conjunction with any documents incorporated by reference in the Original Form 10-K and our filings made with the SEC subsequent to the Original Form 10-K.
