T-Mobile US, Inc. (TMUS) Mar 2026 Filing Analysis
Does management do what it says?
T-Mobile completed the Metronet joint acquisition on July 24, 2025 and invested approximately $4.6 billion during the third quarter, matching the stated target and timeline. (5 met across 5 tracked commitments)
“We currently expect total costs to achieve, excluding accelerated depreciation, to be approximately $2.6 billion, currently expected to be comprised of $1.5 billion of UScellular merger-related costs recognized within operating expenses and $1.1 billion of capital expenditures. Our remaining restructuring and integration activities associated with the UScellular Acquisition are expected to occur over the next two years, with substantially all costs incurred and associated cash payments made by the end of fiscal year 2027.”
Nine-month 2025 property-and-equipment purchases were $7.486 billion versus $6.628 billion in the comparable 2024 period, up 13%. Management states that 2025 capital-expenditure investment is expected to remain at the 2024 level, but full-year delivery cannot yet be assessed. The higher year-to-date spend reflects planned second-half timing, greenfield site builds, and incremental UScellular capital expenditures. (5 in progress across 5 tracked commitments)
“We expect to maintain our investment in capital expenditures related to these efforts in 2026 compared to 2025, as we continue our integration efforts, maintain our commitment to build out our nationwide 5G network and continue our digital journey.”
The filing provides concrete evidence that the fiber strategy is operating and contributing to growth, although no explicit customer or penetration target was provided. (1 in progress across 1 tracked commitment)
“We consider postpaid ARPA to be indicative of our revenue growth potential, given management’s priority on growing high-value accounts through deepening customer relationships.”
Through September 30, 2025, T-Mobile had executed $7.528 billion of share repurchases and paid $2.986 billion of dividends, or approximately $10.514 billion combined. The program remained active with up to $3.6 billion available through December 31, 2025. (4 in progress across 4 tracked commitments)
“We expect to enter into up to a total of $1.2 billion in financing lease commitments during the year ending December 31, 2026.”
Maintain sufficient liquidity to fund operations and anticipated longer-term needs, while using funds for capex, spectrum, acquisitions, debt redemption, dividends, and repurchases. (+1 more commitment)
“Excluding liquidity that could be needed for acquisitions of businesses, spectrum and other long-lived assets, or for any potential stockholder returns, we expect our principal sources of funding to be sufficient to meet our anticipated liquidity needs for business operations for the next 12 months, as well as our longer-term liquidity needs.”

What could break the thesis?
The risk was already significant in Q1 2026: property and equipment purchases rose to $2.623 billion from $2.451 billion, while depreciation and amortization increased 19% to $3.817 billion. Management said capital spending included continued 5G build-out and incremental spending following the UScellular acquisition. The later baseline showed capex rising further to $2.7 billion in Q2 and $5.3 billion for the first six months, with additional spectrum and intangible purchases. This indicates intensifying capital requirements. (1 intensifying)
“Purchases of property and equipment... $2,623 ... $2,451. Net cash used in investing activities... primarily from $2.6 billion in Purchases of property and equipment... for the continued build-out of our nationwide 5G network, including for incremental capital expenditures following the UScellular Acquisition.”
