T-Mobile US (TMUS)

T-Mobile is the fastest-growing wireless carrier in the U.S. (post-Sprint): the best 5G network (leadership in 2.5GHz mid-band spectrum), the lowest churn in the industry (0.93%), sustained market-share gains, and fixed wireless broadband (FWA, +31%) as a new growth engine. The moat is spectrum + network scale + the 3-carrier oligopoly. The Sprint synergies have already been captured → Adjusted FCF inflected to $18bn. It is capital-heavy (low ROIC ~10%) and heavily levered. Deutsche Telekom controls 53% — the governance question mark.

A capital-heavy wireless carrier is valued on EV/EBITDA (the telecom convention): the low multiple charges for the network's heavy capex — EBITDA ignores capex (§4), so at ~8× EBITDA one is effectively paying ~15× operating income (capex ~$12.5bn ≈ depreciation ~$14bn). It is EV-level: net debt ~$88.6bn (a heavily levered balance sheet) is subtracted from enterprise value. GAAP EBITDA is ~$32bn; at ~$182 the EV/EBITDA is ~9× — a premium over Verizon/AT&T (~5.5-7×, mature/declining) justified by the growth.

The base case projects EBITDA compounding ~5-6%/year (share gains + FWA + ARPA + already-captured synergies) to ~$41bn in five years, at an 8× exit multiple (the top of the telecom band, as the growth carrier — but disciplined, compressing from ~9× today toward the peer group as the industry matures). The aggressive buyback (~$12bn/year, ~3.5% of shares) compounds the per-share value above the EBITDA growth rate. That gives ~$270/share → a total return of +11%/year.

It trades at a real discount to value, though short of the required margin of safety. At ~$182 (after falling ~28% from its $262 high) T-Mobile trades at ~9× EV/EBITDA — a compressed multiple for the country's best carrier, driven by a governance overhang (the possible DT merger), not by fundamental deterioration (which keeps compounding: EBITDA +7%, FCF +6%, share gains, FWA +31%). The verdict is Undervalued: the fundamentals are attractive at this price, but Deutsche Telekom's control (53% of shares, 57% of votes, with the right to consent to M&A and even CEO appointments) is a genuine and possibly persistent discount. The adverse scenario (DT imposes a stock-for-stock merger that undervalues minorities, or saturation + price competition compress EBITDA + the multiple to 7×) takes the value below the price; the favorable one (the merger resolves fairly or does not happen, and FCF growth + the buyback + FWA compound + a re-rating) is a clear upside. The asymmetry is favorable operationally — the overhang discount is the opportunity — but DT's control is the risk that must be accepted.

Three things, with governance at the forefront. The Deutsche Telekom merger (the central disconfirming risk) — if DT proceeds with a stock-for-stock offer, the terms (does it reflect T-Mobile's standalone value, or does it dilute minorities with DT's lower-margin operations?) determine everything; a fair resolution (or the status quo) unlocks the value, an unfavorable one destroys it. Operating fundamentals — churn (0.93%, industry-leading), postpaid account gains, and FWA broadband (+31%) are the metrics showing the engine keeps running; a slowdown from saturation/competition is the operating risk. And cash flow + the buyback — Adjusted FCF ($18bn) and its deployment (~$30bn of buyback+dividend in 2026-27 + $22bn discretionary) compound the per-share value; if debt or the merger divert that capital, the compounding stalls. If the DT overhang resolves fairly, T-Mobile at this price is the best carrier at a discount; if DT imposes an unfavorable transaction, the minority shareholder pays the price.
