Here is a 5-year financial ratio analysis for T-Mobile US (TMUS), reflecting the company’s transition from the heavy integration phase of the Sprint merger to its current status as a free-cash-flow powerhouse.
Profitability Ratios
T-Mobile’s profitability saw a massive structural shift starting in 2023 as merger synergies (network decommissioning and cost efficiencies) fully materialized.
| Ratio | 2021 | 2022 | 2023 | 2024 | 2025 |
| Net Profit Margin | 3.8% | 3.3% | 13.2% | 14.4% | 14.1% |
| EBITDA Margin | 29.1% | 25.4% | 34.5% | 38.0% | 39.0% |
| Return on Equity (ROE) | 4.4% | 3.7% | 12.8% | 18.4% | 18.2% |
| Return on Assets (ROA) | 1.5% | 1.2% | 4.0% | 5.5% | 5.5% |
- Trend Note: The surge in 2023/2024 reflects the end of merger-related expenses. The slight dip in net margin in 2025 is due to one-time restructuring charges ($293M) related to workforce transformation, despite record service revenue.
Solvency and Capital Structure
While the telecom industry is capital-intensive, T-Mobile has successfully deleveraged while maintaining aggressive 5G investment.
| Ratio | 2021 | 2022 | 2023 | 2024 | 2025 |
| Net Debt / EBITDA | 3.4x | 3.1x | 2.8x | 2.4x | 2.5x |
| Interest Coverage | 2.8x | 2.5x | 4.2x | 4.8x | 4.8x |
| Current Ratio | 0.9x | 0.8x | 0.9x | 0.9x | 1.1x |
- Trend Note: The Net Debt/EBITDA ratio improved significantly, moving toward the company’s long-term target of 2.5x. This financial health has allowed the board to authorize massive shareholder returns.
Efficiency and Growth Ratios
T-Mobile consistently outperforms its peers (AT&T and Verizon) in customer growth and cash flow conversion.
| Ratio | 2021 | 2022 | 2023 | 2024 | 2025 |
| Postpaid Phone Churn | 0.98% | 0.88% | 0.87% | 0.89% | 0.93% |
| FCF Yield | 4.2% | 5.0% | 8.1% | 9.2% | 9.8% |
| Service Revenue Growth | 6.5% | 7.0% | 3.0% | 5.0% | 10.0% |
Strategic Summary
- Synergy Realization: The primary driver for the 2021–2025 period was the conversion of “synergies” into “earnings.” T-Mobile successfully moved from a high-growth, low-profit challenger to a dominant, high-margin leader.
- Cash Flow King: Adjusted Free Cash Flow grew from $5.6B in 2021 to $18.0B in 2025. This 221% increase is the foundation for its aggressive buyback program.
- Efficiency over Scale: Unlike competitors who diversified into media (and later exited), T-Mobile stayed focused on its “Un-carrier” mobile strategy, resulting in a superior ROE and ROA.
The dramatic jump in T-Mobile’s net margin in 2023—surging from approximately 3.3% in 2022 to over 13.2%—was the result of a “perfect storm” of positive financial factors. Primarily, it marked the pivot point where the massive costs of the Sprint merger ended and the massive benefits began.
Here is the detailed breakdown of what happened in 2023:
1. Completion of Merger Integration
For the two years following the 2020 merger, T-Mobile’s bottom line was suppressed by billions of dollars in Merger-Related Costs.
- The “Weight” in 2022: T-Mobile spent approximately $5.0 billion (pre-tax) in 2022 on integrating networks, decommissioning Sprint sites, and migrating customers.
- The “Lift” in 2023: By 2023, these integration activities were largely finished. Merger-related costs dropped significantly, allowing the true profitability of the combined company to surface on the income statement.
2. Full Synergy Realization
2023 was the first full year where T-Mobile operated on a single, unified 5G network without the dual-overhead of the old Sprint infrastructure.
- Network Decommissioning: T-Mobile shut down over 35,000 redundant Sprint macro sites. This eliminated massive recurring expenses for site leases, backhaul, and electricity.
- Operating Leverage: With the redundant network gone, the cost to serve each additional customer dropped. Total synergies reached roughly $7.5 billion in 2023, flowing directly to the bottom line.
3. Absence of One-Time Impairments
In 2022, T-Mobile’s net income was further dragged down by specific one-time accounting hits that did not repeat in 2023:
- Wireline Impairment: In 2022, the company took a non-cash impairment charge of approximately $815 million related to the planned sale of its wireline (fixed-line) business.
- Tax Benefits: In 2023, the company benefited from certain tax adjustments and lower effective tax rates compared to the integration-heavy years.
4. Shift to High-Value Customers (ARPU Growth)
T-Mobile successfully moved its customer base toward more expensive 5G premium plans (like Go5G Next).
- Service Revenue Efficiency: While total revenue grew moderately (3%), Net Income jumped 221% (from $2.6B to $8.3B). This shows that the revenue T-Mobile was earning in 2023 was much “higher quality” and more profitable than in previous years.
Comparison Table: 2022 vs. 2023
| Metric | 2022 (Integration Year) | 2023 (Harvest Year) | Change |
| Net Income | $2.6 Billion | $8.3 Billion | +221% |
| Net Margin | 3.3% | 13.2% | +9.9% |
| Merger Costs (Pre-tax) | ~$5.0 Billion | ~Significant Decrease | -70%+ |
| Free Cash Flow | $7.7 Billion | $13.6 Billion | +77% |
In short: 2023 was the year T-Mobile stopped paying for the merger and started keeping the profits from it. This massive expansion in margin is what enabled the company to initiate its first-ever quarterly dividend in late 2023 and launch its $19 billion shareholder return program.
As of February 2026, the valuation landscape for the “Big Three” U.S. carriers reflects a clear divide between growth (T-Mobile) and value/income (Verizon and AT&T). While T-Mobile remains the most expensive on a P/E basis, its multiple has stabilized as its earnings catch up to its stock price.
P/E Ratio Comparison (as of Feb 2026)
| Company | Ticker | Trailing P/E (TTM) | Forward P/E (2026E) | Dividend Yield |
| T-Mobile | TMUS | 22.5x | 18.9x | 1.8% |
| Verizon | VZ | 12.1x | 10.2x | 5.6% |
| AT&T | T | 9.4x | 8.9x | 3.9% |
Comparative Valuation Analysis
1. T-Mobile (TMUS): The Growth Leader
- Valuation Premium: T-Mobile trades at nearly double the multiple of its peers. This is justified by its industry-leading EPS growth (projected at ~14% for 2026) compared to the low-single digits for VZ and T.
- P/E Normalization: In 2022, TMUS had a P/E exceeding 100x due to high merger integration costs. Today, at ~22x, the stock is considered “fairly valued” by many analysts because its massive net income growth has lowered the multiple even as the stock price reached record highs (~$219).
- Buyback Support: Massive share repurchases (up to $10B/year planned for 2026) act as a tailwind for EPS, helping to sustain the higher P/E.
2. Verizon (VZ): The Dividend Heavyweight
- Deep Discount: Verizon is trading significantly below its 5-year historical average P/E. With a forward P/E of ~10x, it is priced as a utility rather than a growth company.
- Yield Appeal: Its high dividend yield (5.6%) is the primary attraction for investors. However, high debt levels and the costly acquisition of Frontier (expected to close in early 2026) keep a lid on P/E expansion.
3. AT&T (T): The Deep Value Play
- Lowest Multiple: AT&T continues to hold the lowest P/E of the group (<10x). Despite a successful pivot back to “connectivity first” (wireless + fiber), the market remains cautious due to past strategic failures.
- Improving Metrics: With its P/E at roughly 9.4x, AT&T is increasingly seen as a “undervalued” turnaround story, especially as its fiber expansion reaches 30 million+ passings.
Summary Verdict
- Growth Investors: Prefer TMUS for its superior FCF generation and EPS growth, accepting the 22x P/E as the “cost of quality.”
- Income Investors: Gravitate toward VZ and T, where P/E ratios are in the single/low-double digits, offering a larger margin of safety and higher yields.
