Telephone Data (TDS) Q3 2026 Earnings Call Transcript

TDS Telecom added a record 17,000 residential fiber connections in Q3, up 50% year over year, and delivered 76,000 marketable fiber addresses; Array site rental revenue grew 14% to $52.5 million. TDS lowered full-year telecom revenue guidance to $990 million–$1.01 billion and adjusted EBITDA guidance to $290 million–$310 million, citing legacy revenue pressure and higher costs, while raising 2026 telecom CapEx guidance by $100 million from the prior midpoint to $750 million. The board authorized an additional $250 million in share repurchases after the prior $520 million authorization was virtually exhausted.

Analysis

TDS’s key issue is not fiber demand but the lag between construction spend and cash earnings. Record adds and improving churn support the demand case, yet they do not establish attractive returns on the accelerated builds: buried construction, extended service hours, and a larger work-in-progress pipeline are already pressuring EBITDA. The near-term risk is that legacy copper and coax losses persist longer than management’s “around the corner” inflection, leaving TDS to fund growth while profitability contracts. Fixed-wireless offers from T-Mobile and Verizon and satellite broadband are less compelling substitutes where fiber is available, but can constrain pricing and take-up at the margins in expansion markets.

For Array Digital Infrastructure (AD), the operating picture is relatively better, but reported growth should not be extrapolated: the T-Mobile master lease supports revenue while network integration creates a multi-year risk of vacated sites. Ground-lease buyouts can protect tower-level economics, but require capital and do not by themselves replace lost tenants. The failed TDS combination removes a potential simplification catalyst; the separate companies should be valued on their own cash flows. Spectrum monetization is optionality, not a base-case earnings driver until proceeds and terms are disclosed.

Over the next 1–3 months, watch TDS’s Q4 EBITDA and fiber conversion versus build pace, plus year-end spectrum-sale closing. Over 6–18 months, penetration, build cost per passing, and tower tenant replacement determine whether growth converts to returns. The contrarian risk: the market may over-penalize TDS’s investment phase if fiber penetration compounds, but current adds alone are insufficient proof. A sustained EBITDA recovery alongside legacy stabilization would falsify the cautious view; further guidance cuts or rising unit build costs would reinforce it.

Key Decisions for Investors

• TDS: Underweight rather than initiate an aggressive outright short; use rallies to trim until quarterly fiber revenue growth demonstrably offsets legacy declines without further EBITDA deterioration. Reassess on Q4 results and the next guidance update.
• TDS alert: Track build cost per passing, fiber penetration by cohort, and cash expenses. The investment thesis weakens if costs continue rising while new-market penetration falls short of the stated trajectory or legacy losses accelerate; improvement in those measures would argue for adding exposure.
• AD: Hold/watch rather than chase the lease-driven growth. Revisit after clearer disclosure on T-Mobile site designations through January 2028, tenant replacement, and ground-lease buyout returns; a rising number of uneconomic or tenantless sites is the key downside trigger.
• Treat the approved spectrum sale and potential C-band monetization as catalysts only when closing proceeds and terms are public. Do not capitalize unspecified proceeds into either company’s base-case value.
