What Could T-Mobile Stock Be Worth In Three Years?

T-Mobile US (TMUS) stock lost 30.1% over the year to October 15, 2026, dividends included. During the same period, the S&P 500 gained 17.9%. The decline has left a company still growing its sales priced below its own historical baseline: the shares currently trade at 16.2 times earnings, against an average of 21.9 across its last twelve fiscal quarter-ends. So how much of that lost ground could T-Mobile win back over the next three years.
