T-Mobile US, Inc. (NASDAQ:TMUS) shares rallied on Tuesday after the carrier expanded its fiber broadband push through new partnerships aimed at widening its next-generation home internet footprint. The company disclosed two major strategic fiber joint ventures.

The first is a 50/50 partnership with Oak Hill Capital to acquire and combine GoNetspeed and Greenlight Networks, while the second is a 50/50 JV with Wren House to acquire i3 Broadband.

Overall, these transactions further support T-Mobile's long-term goal of reaching 18–19 million total broadband customers by 2030, including 3–4 million fiber subscribers.

JV With Oak Hill Capital

Under the arrangement, T-Mobile will acquire a 50% stake in a combined entity that brings together Oak Hill's fiber assets GoNetspeed and Greenlight Networks.

The platform will expand T-Fiber's residential broadband footprint across attractive Northeastern U.S. markets, including Connecticut, Maine, Maryland, Massachusetts, New Jersey, New York, Pennsylvania, and Rhode Island.

The combined network is projected to reach more than 1.3 million homes passed by the end of 2026.

The transaction is expected to close in the first half of 2027. At which point, T-Mobile plans to invest about $2.0 billion to acquire a 50% stake in the joint venture along with substantially all existing residential fiber customers.

Wren House JV

In a separate deal, T-Mobile will enter into a 50/50 joint venture with global infrastructure investor Wren House to acquire i3 Broadband, a fiber-to-the-premises provider serving residential customers.

The transaction adds i3 to T-Mobile's expanding fiber portfolio, further strengthening its base of scalable FTTP assets supported by experienced operators and long-term infrastructure investment.

i3 Broadband is expected to reach around 500,000 homes passed by the end of 2026 across its existing footprint, including markets in Missouri, Illinois, and Rhode Island.

The Wren House deal is expected to close in the second half of 2026. At that time, the company will invest around $700 million for a 50% interest in the JV and substantially all current residential fiber subscribers.

T-Mobile US reported $5.6 billion in cash and cash equivalents for the fiscal quarter ending in December 2025.

T-Mobile Technical Analysis

T-Mobile is sitting near the bottom of its 52-week range after a sharp drawdown, which keeps the longer-term trend tilted lower. The stock is trading 5.9% below its 20-day simple moving average (SMA) and 8.6% below its 100-day SMA, a setup that leans toward sellers still controlling the intermediate trend even with today's bounce.

The relative strength index (RSI), a momentum gauge, is 30.82, which is near the oversold threshold and can coincide with short-term stabilization attempts. RSI at 30.82 shows selling pressure has been heavy enough that rebounds can appear quickly, even if the bigger trend hasn't flipped.

The death cross that formed in October 2025 (50-day SMA below the 200-day SMA) still hangs over the chart, which is consistent with a market that has been rewarding rallies less and punishing weakness more. Over the past 12 months, the stock is down 21.76%, reinforcing that this is still a longer-term repair story rather than a clean uptrend.

  • Key Resistance: $207.00 — a prior ceiling where rebounds have struggled to keep traction.
  • Key Support: $181.50 — a nearby floor where buyers have recently shown up.

TMUS ETF Exposure: Key Funds to Watch

  • The Communication Services Select Sector SPDR Fund (NYSE:XLC): 4.55% Weight
  • State Street Communication Services Select Sector SPDR ETF (NYSE:XLC): 4.56% Weight
  • iShares U.S. Telecommunications ETF (BATS:IYZ): 4.10% Weight

Significance: Because TMUS carries significant weight in these funds, any significant inflows or outflows for these ETFs will likely force automatic buying or selling of the stock.

TMUS Stock Price Activity: T-Mobile US shares were up 1.53% at $185.55 at the time of publication on Tuesday, according to Benzinga Pro data.
