Key Takeaways
- • T-Mobile invested $950 million for a 50% equity stake in a joint venture with EQT to acquire fiber operator Lumos, with an additional $500 million planned between 2027 and 2028 to support network expansion.
- • The Lumos joint venture targets 3.5 million homes by the end of 2028, building on Lumos' current 7,500-mile fiber network serving 475,000 homes across the Mid-Atlantic region.
- • Combined with T-Mobile's separate $4.9 billion joint venture with KKR to acquire Metronet (which now passes 3 million locations after acquiring US Internet), the two fiber deals provide T-Mobile with infrastructure passing approximately 15 million locations.
- • The strategy positions T-Mobile to transition Lumos to a wholesale model with T-Mobile as the anchor tenant, leveraging the carrier's retail footprint, brand, and customer service capabilities to drive subscriber acquisition across underserved markets.
- • T-Mobile expects to add at least 100,000 net new fiber connections by year-end 2025, representing a modest but disciplined approach to fiber profitability compared to Verizon and AT&T's larger fiber investments.
Summary
T-Mobile closed a major fiber-to-the-home acquisition on April 1, 2025, finalizing its joint venture with EQT to acquire Lumos Networks for approximately $950 million in initial T-Mobile equity investment. The deal represents a critical infrastructure milestone for the Un-carrier's broadband diversification strategy, complementing its fixed wireless offerings with a wired fiber backbone.
Under the transaction structure, T-Mobile acquired a 50% equity stake in the joint venture while committing an additional $500 million between 2027 and 2028 for continued network buildout. Lumos currently operates a 7,500-mile fiber network providing high-speed connectivity to 475,000 homes across the Mid-Atlantic region. The joint venture aims to expand this footprint to 3.5 million homes by the end of 2028, leveraging EQT's infrastructure investment expertise and Lumos' proven build capabilities alongside T-Mobile's retail, marketing, and customer experience assets. Following the close, Lumos will transition to a wholesale operating model with T-Mobile as the anchor tenant and primary customer interface, allowing the carrier to deploy its nationwide brand and sales infrastructure to capture new subscribers in previously underserved markets.
The Lumos transaction follows T-Mobile's separate $4.9 billion joint venture with investment firm KKR to acquire Metronet, which closed in mid-2024. Metronet has achieved a three million location reach across 19 states and over 300 communities, including through its September 2024 acquisition of Minneapolis-based US Internet. Combined, these two fiber initiatives provide T-Mobile with infrastructure passing approximately 15 million locations, establishing the carrier as a meaningful competitor in fiber-to-the-home markets despite still lagging behind Verizon and AT&T in absolute fiber deployment.
T-Mobile management has adopted a measured near-term revenue approach, with CEO guidance targeting at least 100,000 net new fiber connections by the end of 2025. This disciplined posture contrasts with competitors' more aggressive fiber spending strategies and reflects management's focus on achieving value accretion while building scalable infrastructure for longer-term broadband revenue growth.
