Full Analysis
T-Mobile US (TMUS) shares fell 7.7% on Friday, October 23, 2026, driven by reports that SpaceX is seeking to lease at least 80,000 U.S. cell sites to build a fourth nationwide wireless carrier. The company did not report earnings on this day, but the news raised concerns about potential fierce competition for postpaid service revenue from the industry's big three carriers. Management had previously noted on the July 23, 2026 call that postpaid service revenue rose 13% in the second quarter. However, the stock has struggled recently, dropping 16.8% from July 27 to October 23, 2026, while the S&P 500 gained 3.1%. Friday's close of $146.54 marked the stock's lowest price in a year. T-Mobile trades at 1.7 times its sales over the last twelve months, significantly lower than the S&P 500 multiple of 3.2 times. The company is scheduled to report its third-quarter results later in October 2026, with management expecting net postpaid account additions of about 250,000 for that quarter. Account growth is expected to be held back by a temporary rise in churn resulting from the company's rate plan modernization. This figure remains the primary metric investors will watch when the earnings report is released later this month.
