Uniti’s Fiber Expansion Is Outrunning Its Internal Cash Generation

Uniti is building fiber faster than its operations are generating cash. The company spent about $1.4 billion on property and equipment over the 12 months through June 2026, according to the original analysis, while quarterly free cash flow remained negative for four consecutive periods.

The expansion has a clear operating goal. Uniti’s Kinetic business aims to pass 3.5 million homes with fiber by the end of 2029, up from roughly 2.1 million at the end of June 2026. Management has pointed to accelerating demand from hyperscalers, neocloud providers and residential customers. The second-quarter release also showed Fiber Infrastructure revenue of $234.1 million with a contribution margin near 52%.

The balance sheet makes the pace important. The original report calculated about $11.1 billion of debt and lease obligations against roughly $600 million of cash. Uniti has discussed asset sales over a 12-to-36-month window, which could provide liquidity, but proceeds, timing and the effect on future earnings remain uncertain. The Windstream merger also complicates year-over-year comparisons because much of the reported sales growth reflects the larger combined company.

Management’s 2026 spending plan was about $1.525 billion net of upfront customer payments, with part of the Kinetic build pulled forward from 2027. Pulling work forward can accelerate service availability, but it also concentrates cash needs before the network reaches mature penetration.

The investment case therefore rests on conversion. Homes passed must become paying customers, contracted fiber capacity must produce cash margins, and any asset sales must strengthen rather than hollow out the business. Until those measures improve, revenue growth alone will not prove that the construction program is earning an adequate return.
