United States Cellular Corp (USM) saw its stock plummet by 5.65% in pre-market trading on Friday, following the release of its fourth-quarter earnings results and a gloomy outlook for the future.

The mobile telecommunications company reported a net income of $5 million, or $0.05 per diluted share, for the fourth quarter of 2024, down significantly from the $14 million, or $0.16 per share, recorded in the same period a year earlier. This disappointing performance missed analysts' expectations of a loss of $0.03 per share.

Total operating revenue for the quarter also declined to $970 million, compared to $1 billion in the previous year, although it slightly exceeded analysts' projections of $960.3 million.

The company's weak performance was further compounded by a lack of guidance for the upcoming year, as United States Cellular stated that due to the pending transaction with T-Mobile, it would not provide any financial projections for 2025. This decision has left investors uncertain about the company's future prospects, contributing to the sharp sell-off in pre-market trading.

Despite the disappointing results, United States Cellular highlighted some positive developments during the year, including improved wireless operating results, ongoing 5G mid-band network deployment, and progress in its strategic alternatives review. However, these efforts appear to have been overshadowed by the company's lackluster financial performance and uncertain outlook.
