    Introduction

    Telecom valuation requires a different toolkit than valuing software or internet companies. While SaaS companies trade on revenue multiples and internet platforms on user engagement metrics, telecom carriers are valued primarily on EV/EBITDA because EBITDA captures the operating cash flow generation that drives dividend sustainability, debt service capacity, and network reinvestment potential. The valuation gap within telecom is significant: US wireless carriers trade at 7-10x EV/EBITDA, tower companies at 20-25x AFFO, and European carriers at 5-7x. Understanding why these multiples differ, and what drives them to expand or contract, is essential for TMT analysts covering the sector.

    EV/EBITDA: The Core Telecom Multiple

    Why EV/EBITDA Dominates Telecom Valuation

    EV/EBITDA is preferred over P/E in telecom for several reasons. First, telecom companies carry very different capital structures (AT&T at 3.3x net debt/EBITDA versus T-Mobile at 3.8x), and EV/EBITDA normalizes for leverage by comparing enterprise value (which includes debt) against a pre-interest metric. Second, depreciation and amortization charges in telecom are massive (reflecting decades of network infrastructure investment) but do not accurately represent the true economic cost of maintaining the network, making net income a poor measure of operating performance. Third, tax positions vary significantly across carriers due to spectrum amortization, accelerated depreciation, and deferred tax assets, which distort earnings-based multiples.

    US wireless carrier EV/EBITDA multiples have historically ranged from 6-10x, with the range reflecting each carrier's growth profile and competitive positioning. T-Mobile trades at approximately 10x EV/EBITDA, a premium driven by its faster subscriber growth, higher EBITDA margins (exceeding 39% in 2025, targeting 40-41% in 2026), and lower capex intensity that translates into superior free cash flow conversion. AT&T and Verizon trade at 7-8x, reflecting their mature subscriber bases, higher capex requirements, and legacy business headwinds. Operators that progress on structural unbundling (separating infrastructure from service operations) command EV/EBITDA premiums of 30-50% over integrated peers, which explains much of T-Mobile's valuation advantage.

    European carriers trade at lower multiples (5-7x), reflecting more fragmented markets with 3-4 competitors per country, stricter regulatory environments that limit pricing power, and lower ARPU. The US median EV/EBITDA for technology and telecommunications was approximately 13.3x in 2024, compared to 9.3x in Western Europe.

    EV/Subscriber and Per-Unit Metrics

    Additional per-unit metrics used in telecom valuation include EV/MHz-POP for spectrum holdings (standardizing value across frequency bands and geographic markets), EV/home passed for fiber and cable networks (measuring the value of the network footprint regardless of current penetration), and revenue per tower for tower companies (reflecting the colocation density and rental rates of the portfolio).

    Interview Question #1Easy

    How do you value a telecom company, and what are the key multiples?

    Telecom valuation uses three primary approaches.

    EV/EBITDA is the most common multiple, applied to stabilized telecom carriers. Typical ranges: US wireless carriers (7-8x), European carriers (5-7x, reflecting lower growth and profitability), tower companies (20-30x, reflecting contracted recurring revenue and growth).

    EV/Subscriber values each customer relationship. It is useful for comparing carriers with different ARPU levels and for assessing acquisition pricing. Typical ranges: US wireless subscriber values of $3,000-5,000, European wireless at $1,500-3,000.

    DCF is used for infrastructure assets (towers, fiber) with long-lived, contracted cash flows. Discount rates of 7-9% are typical, reflecting the low-risk, utility-like cash flow profile.

    Key adjustments:

    1. Spectrum normalization. Exclude one-time spectrum purchases from capex to calculate "maintenance capex" for recurring free cash flow.

    2. Lease adjustments. Under IFRS 16/ASC 842, operating leases are capitalized, which affects both EBITDA and debt calculations. Ensure comparability across companies.

    3. Convergence premium/discount. Carriers offering bundled fixed-mobile services may warrant a premium for reduced churn, while pure-play wireless may warrant a premium for higher margins.
