**EXHIBIT 99.1**

**T-Mobile Delivers Best-in-Class Customer Results in Q4, Translating into Durable and Profitable Financial Growth Driven By Widening Differentiation**

***Q4 Yet Another Proof Point of the Un-carrier's Widening Pillars of Differentiation Leading to Sustained Outperformance, Including First-Ever J.D. Power Award for Highest Network Quality, Positioning T-Mobile for Continued Profitable Growth in 2026 and Beyond***

**<u>Industry-Leading Customer Growth Fueled by Widening Differentiation in Best Network, Best Value and Best Experiences Combination</u>**<sup>(1)</sup>

• Total postpaid net customer additions of 2.4 million in Q4 2025 and 7.8 million in 2025, both industry best

• Postpaid phone net customer additions of 962 thousand in Q4 2025 and 3.3 million in 2025, both industry best

• Postpaid net account additions of 261 thousand in Q4 2025 and 1.2 million in 2025, both industry best

• Total broadband net customer additions of 558 thousand in Q4 2025 and 2.0 million in 2025, both industry best

**<u>Translating Industry-Leading Customer Growth into Durable and Profitable Financial Growth</u>**

• Service revenues of $18.7 billion in Q4 2025 and $71.3 billion in 2025, both industry-leading growth

• Postpaid service revenues of $15.4 billion in Q4 2025 and $57.9 billion in 2025, both industry-leading growth

• Strong net income of $2.1 billion in Q4 2025 and $11.0 billion in 2025

**<u>Extending Overall Network Lead with Best Assets, Customer Centricity and Technology Leadership</u>**

• For the first time ever, customers have rated T-Mobile highest for network quality in five of six regions in the J.D. Power 2026 U.S. Wireless Network Quality Study. This milestone reflects the impact of T-Mobile's long-term network strategy, as customers rated the company highest for network quality across more U.S. regions than at any point in its history—well above its previous high of two regions and notably ending a run of 35 consecutive reports with a competitor leading the category.

• T-Mobile won all five overall network experience categories from Opensignal, along with 5G Coverage Experience and 5G Availability. Network consistency remains a key differentiator as T-Mobile was awarded back-to-back outright wins in both Reliability Experience and Consistent Quality.

• T-Mobile once again recognized as the Best Mobile Network in the U.S. according to Ookla's latest Speedtest Connectivity report after an initial win in July 2025 in the largest, most-comprehensive tests of their kind, each leveraging half a billion real world data points on millions of devices measuring speed and experience. In addition, T-Mobile was awarded the best and fastest 5G network, alongside other awards for best mobile gaming and video streaming experience.

**Bellevue, WA — February 11, 2026** — T-Mobile US, Inc. (NASDAQ: TMUS) reported fourth quarter and full year 2025 results today, delivering industry-leading customer results across the board, in postpaid net account additions, total postpaid net customer additions, postpaid phone net customer additions, and total broadband net customer additions. The company's industry-leading customer and customer account growth contributed to industry-best service revenue growth, which grew at a rate multiple times that of its closest wireless competitors, strong net income, industry-leading Core Adjusted EBITDA growth, strong net cash provided by operating activities and industry-leading Adjusted Free Cash Flow margin in 2025, while fueling stockholder returns of $14.0 billion. The Company will also provide an update to its multi-year guidance through 2027, originally presented at its September 2024 Capital Markets Day, during its upcoming Capital Markets Day Update event which will be available via webcast and in a separate press release concurrent with the event on the Investor Relations website, in addition to the company's release earlier this morning announcing a first-of-its-kind network-integrated service that enables real-time translation during phone calls, here.

"Q4 was a great proof point of our winning formula – and we see significant runway ahead to widen our margin of differentiation, including through maintaining our tremendous momentum in network perception gains and in our digital transformation and simplification," said Srini Gopalan, CEO of T-Mobile. "In 2025, more new postpaid customers chose the Un-carrier than ever before, driven by outstanding momentum across all categories. As we look to 2026, we're even more confident that the future is brighter than ever before. We see continued opportunity to eliminate customer pain points, introduce even more consumers to the Un-carrier ethos, and further extend our network leadership while accelerating our digital transformation to drive durable and outsized profitable growth. I'm tremendously excited to share more during our expanded format earnings call and 2024 Capital Markets Day halftime check-in - stay tuned."

(1)AT&T Inc. does not disclose postpaid net account additions. Comcast and Charter do not disclose postpaid phone net customer additions. Industry-leading claims are based on consensus expectations if results are not yet reported.

(2)Core Adjusted EBITDA and Adjusted Free Cash Flow are non-GAAP financial measures. These non-GAAP financial measures should be considered in addition to, but not as a substitute for, the information provided in accordance with GAAP. Reconciliations for these non-GAAP financial measures to the most directly comparable GAAP financial measures are provided in the Reconciliation of Non-GAAP Financial Measures to GAAP Financial Measures tables. We are not able to forecast Net income on a forward-looking basis without unreasonable efforts due to the high variability and difficulty in predicting certain items that affect Net income, including, but not limited to, Special Items, Income tax expense and Interest expense. Core Adjusted EBITDA should not be used to predict Net income as the difference between this measure and Net income is variable.

See 5G device, coverage, and access details at T-Mobile.com. J.D. Power Award: The 2026 U.S. Wireless Network Quality Performance Study—Volume 1 is based on responses from 20,050 wireless customers. Carrier performance is examined in six regions: Mid-Atlantic, North Central, Northeast, Southeast, Southwest and West. In addition to evaluating the network quality experienced by customers with wireless phones, the study also measures the network performance of tablets and mobile broadband devices.

**<u>Strong Outlook for 2026 with Continued Industry-Leading Growth</u>**

• Postpaid net account additions are expected to be between 900 thousand and 1.0 million.

• Core Adjusted EBITDA, which is Adjusted EBITDA less lease revenues, is expected to be between $37.0 billion and $37.5 billion, up 10% year-over-year at the midpoint.

• Net cash provided by operating activities, including payments for UScellular merger-related costs, is expected to be between $28.0 billion and $28.7 billion.

• Cash purchases of property and equipment, including capitalized interest, are expected to be approximately $10.0 billion.

• Adjusted Free Cash Flow, including payments for UScellular merger-related costs, is expected to be between $18.0 billion and $18.7 billion. Adjusted Free Cash Flow guidance does not assume any material net cash inflows from securitization.

The company will also provide an update to its multi-year guidance through 2027, originally presented at its September 2024 Capital Markets Day, during its upcoming Capital Markets Day Update event which will be available via webcast and in a separate press release concurrent with the event on the Investor Relations website, in addition to the company's release earlier this morning announcing a first-of-its-kind network-integrated service that enables real-time translation during phone calls, here.

(1)T-Mobile is not able to forecast Net income on a forward-looking basis without unreasonable efforts due to the high variability and difficulty in predicting certain items that affect GAAP Net income, including, but not limited to, Special Items, Income tax expense and Interest expense. Core Adjusted EBITDA should not be used to predict Net income as the difference between this measure and Net income is variable.

(2)Management uses Core Adjusted EBITDA as a measure to monitor the financial performance of company operations, excluding the impact of lease revenues from related device financing programs.

(3)Capital expenditures means cash purchases of property and equipment, including capitalized interest.

**Reconciliation of Non-GAAP Financial Measures to GAAP Financial Measures**

**(Unaudited)**

This Press Release includes non-GAAP financial measures, including Adjusted EBITDA, Core Adjusted EBITDA, Adjusted Free Cash Flow and Adjusted Free Cash Flow margin. The non-GAAP financial measures should be considered in addition to, but not as a substitute for, the information provided in accordance with GAAP. Reconciliations for the non-GAAP financial measures to the most directly comparable GAAP financial measures are provided below. T-Mobile is not able to forecast Net income on a forward-looking basis without unreasonable efforts due to the high variability and difficulty in predicting certain items that affect GAAP net income, including, but not limited to, Special Items, Income tax expense and Interest expense. Adjusted EBITDA and Core Adjusted EBITDA should not be used to predict Net income as the difference between either of these measures and Net income is variable.

Adjusted EBITDA and Core Adjusted EBITDA are reconciled to Net income as follows:

(1)Stock-based compensation includes payroll tax impacts and may not agree to stock-based compensation expense in the Condensed Consolidated Financial Statements. Additionally, certain stock-based compensation expenses associated with the Sprint merger have been included in Merger-related costs (gain), net.

(2)Merger-related costs (gain), net includes Sprint merger-related costs and UScellular merger-related costs.

(3)Merger-related costs (gain), net, for the three months ended June 30, 2024 and the year ended December 31, 2024, includes the $100 million gain recognized for the extension fee previously paid by DISH associated with the DISH License Purchase Agreement.

(4)In Q4 2025, we began implementing network restructuring initiatives as a result of recent technological advancements that enhanced our Customer-Driven Coverage insights. Network restructuring initiative costs consist of network decommissioning and contract termination costs related to the rationalization of our network and backhaul services and the elimination of duplicative costs.

(5)Legal-related expenses (recoveries), net consists of the settlement of certain litigation and compliance costs associated with the August 2021 cyberattack, net of insurance recoveries.

(6)Other, net, primarily consists of certain severance, restructuring and other expenses, gains and losses, not directly attributable to the Sprint merger or UScellular acquisition, which are not reflective of T-Mobile's ongoing core business activities and are, therefore, excluded from Adjusted EBITDA and Core Adjusted EBITDA. Other, net for the three months and year ended December 31, 2025, includes $390 million of severance and related costs associated with the 2025 workforce reduction.

Adjusted EBITDA represents earnings before Interest expense, net of Interest income, Income tax expense, Depreciation and amortization, stock-based compensation and certain expenses, gains and losses, which are not reflective of our ongoing operating performance ("Special Items"). Special Items include Merger-related costs (gain), net, costs associated with the network restructuring initiative (as discussed above), certain legal-related expenses and recoveries, Impairment expense, restructuring costs not directly attributable to the Sprint merger or UScellular acquisition (including severance), and other non-core gains and losses. Core Adjusted EBITDA represents Adjusted EBITDA less device lease revenues. Core Adjusted EBITDA and Adjusted EBITDA are non-GAAP financial measures utilized by T-Mobile's management, including our chief operating decision maker, to monitor the financial performance of our operations and allocate resources of the company as a whole. T-Mobile uses Core Adjusted EBITDA and Adjusted EBITDA as benchmarks to evaluate T-Mobile's operating performance in comparison to its competitors. T-Mobile also uses Core Adjusted EBITDA internally as a measure to evaluate and compensate its personnel and management for their performance. Management believes analysts and investors use Core Adjusted EBITDA and Adjusted EBITDA as supplemental measures to evaluate overall operating performance and to facilitate comparisons with other wireless communications and broadband services companies because they are indicative of T-Mobile's ongoing operating performance and trends by excluding the impact of Interest expense from financing, non-cash depreciation and amortization from capital investments, non-cash stock-based compensation, and Special Items. Management believes analysts and investors use Core Adjusted EBITDA because it normalizes for the transition in the company's device financing strategy, by excluding the impact of device lease revenues from Adjusted EBITDA, to align with the related depreciation expense on leased devices, which is excluded from the definition of Adjusted EBITDA. Core Adjusted EBITDA and Adjusted EBITDA have limitations as analytical tools and should not be considered in isolation or as substitutes for Net income or any other measure of financial performance reported in accordance with U.S. Generally Accepted Accounting Principles ("GAAP").

Effective November 1, 2024, following amendments to the company's Equipment Installment Plan Sale and Service Receivable Sale arrangements, all cash proceeds associated with the sale of such receivables, a portion of which was previously recognized as Proceeds related to beneficial interests in securitization transactions within investing cash flows, were recognized as operating cash flows. These amendments did not have a net impact on Adjusted Free Cash Flow.

Adjusted Free Cash Flow - Net cash provided by operating activities less Cash purchases of property and equipment, plus Proceeds related to beneficial interests in securitization transactions. Adjusted Free Cash Flow is utilized by T-Mobile's management, investors and analysts to evaluate cash available to pay debt, repurchase shares, pay dividends and provide further investment in the business.

Adjusted Free Cash Flow margin - Adjusted Free Cash Flow divided by Service revenues. Adjusted Free Cash Flow margin is utilized by T-Mobile's management, investors, and analysts to evaluate the company's ability to convert service revenue efficiently into cash available to pay debt, repurchase shares and provide further investment in the business.

The guidance range for Adjusted Free Cash Flow is calculated as follows:

During Q2 2025, we acquired 85,000 postpaid accounts from Lumos.

During Q3 2025, we acquired 1,448,000 postpaid accounts, net of certain base adjustments, through the UScellular acquisition.

During Q3 2025, we acquired 633,000 postpaid accounts from Metronet and other acquisitions.

**Year-Over-Year**

**Continued growth in Postpaid accounts with net additions relatively flat primarily due to:**

**■**Higher account deactivations driven by the impact from a growing account base, including following the UScellular acquisition, and higher industry switching

**■**Mostly offset by higher gross account additions, including fiber account additions following the acquisitions of Metronet and Lumos

**Sequential**

**Continued growth in Postpaid accounts with a decrease in net additions primarily due to:**

**■**Higher account deactivations, including seasonal trends, higher industry switching and the impact from a growing account base

**Year-Over-Year**

**Postpaid ARPA increased 3% primarily due to:**

**■**The positive impact from rate plan optimizations and higher fee revenue, including from the adoption of new tax and fee exclusive plans

**■**An increase in customers per account, including from the continued adoption of 5G broadband and continued growth of T-Mobile for Business customers, partially offset by fiber and UScellular accounts with fewer customers per account

■Partially offset by increased promotional activity, including the success of bundled offerings

**Postpaid phone ARPU increased 2% primarily due to:**

■The positive impact from rate plan optimizations and higher fee revenue, including from the adoption of new tax and fee exclusive plans

(1)We are not able to forecast Net income on a forward-looking basis without unreasonable efforts due to the high variability and difficulty in predicting certain items that affect GAAP Net income, including, but not limited to, Special Items, Income tax expense and Interest expense. Core Adjusted EBITDA should not be used to predict Net income as the difference between this measure and Net income is variable.

(2)Management uses Core Adjusted EBITDA as a measure to monitor the financial performance of our operations, excluding the impact of lease revenues from our related device financing programs.

(3)Capital expenditures means cash purchases of property and equipment, including capitalized interest.

**Reconciliation of Non-GAAP Financial Measures to GAAP Financial Measures**

**(Unaudited)**

This Investor Factbook includes non-GAAP financial measures, including Adjusted EBITDA, Core Adjusted EBITDA, Net Debt, Adjusted Free Cash Flow and Adjusted Free Cash Flow margin. The non-GAAP financial measures should be considered in addition to, but not as a substitute for, the information provided in accordance with GAAP. Reconciliations for the non-GAAP financial measures to the most directly comparable GAAP financial measures are provided below. T-Mobile is not able to forecast Net income on a forward-looking basis without unreasonable efforts due to the high variability and difficulty in predicting certain items that affect GAAP net income, including, but not limited to, Special Items, Income tax expense and Interest expense. Adjusted EBITDA and Core Adjusted EBITDA should not be used to predict Net income, as the difference between either of these measures and Net income is variable.

Adjusted EBITDA and Core Adjusted EBITDA are reconciled to Net income as follows:

(1)Stock-based compensation includes payroll tax impacts and may not agree to stock-based compensation expense on the Consolidated Financial Statements. Additionally, certain stock-based compensation expenses associated with the Sprint merger have been included in Merger-related costs (gain), net.

(2)Merger-related costs (gain), net, for the three months ended June 30, 2024 and the year ended December 31, 2024, includes the $100 million gain recognized for the extension fee previously paid by DISH associated with the license purchase agreement for 800 MHz spectrum licenses, which was not purchased.

(3)In Q4 2025, we began implementing network restructuring initiatives as a result of recent technological advancements that enhanced our Customer-Driven Coverage insights. Network restructuring initiative costs consist of network decommissioning and contract termination costs related to the rationalization of our network and backhaul services and the elimination of duplicative costs.

(4)Legal-related expenses (recoveries), net, consists of the settlement of certain litigation and compliance costs associated with the August 2021 cyberattack and is presented net of insurance recoveries.

(5)Other, net, primarily consists of certain severance, restructuring and other expenses, gains and losses, not directly attributable to the Sprint merger or UScellular acquisition, which are not reflective of T-Mobile's ongoing core business activities and are, therefore, excluded from Adjusted EBITDA and Core Adjusted EBITDA. Other, net, for the three months ended and year ended December 31, 2025, includes $390 million of severance and related costs associated with the 2025 workforce transformation.

**Definitions of Terms**

Operating and financial measures are utilized by T-Mobile's management to evaluate its operating performance and, in certain cases, its ability to meet liquidity requirements. Although companies in the telecommunications industry may not define measures in precisely the same way, T-Mobile believes the measures facilitate key operating performance comparisons with other companies in the telecommunications industry to provide management, investors and analysts with useful information to assess and evaluate past performance and assist in forecasting future performance.

**1. Account** - A billing account number that generates revenue. Postpaid accounts generally consist of customers that are qualified for postpaid service utilizing phones, 5G broadband gateways, fiber connections, mobile internet devices, including tablets and hotspots, wearables, DIGITS or other connected devices, including SyncUP and IoT, where they generally pay after receiving service.

**2. Customer** - A SIM number with a unique T-Mobile identifier which is associated with an account that generates revenue. Customers are qualified either for postpaid service utilizing phones, 5G broadband gateways, fiber connections, mobile internet devices, including tablets and hotspots, wearables, DIGITS or other connected devices, including SyncUP and IoT, where they generally pay after receiving service, or prepaid service, where they generally pay in advance of receiving service.

**3. Churn** - The number of customers whose service was deactivated as a percentage of the average number of customers during the specified period further divided by the number of months in the period. The number of customers whose service was deactivated is presented net of customers that subsequently have their service restored within a certain period of time and excludes customers who received service for less than a certain minimum period of time.

**4. Postpaid Average Revenue Per Account ("ARPA")** - Average monthly postpaid service revenue earned per account. Postpaid service revenues for the specified period divided by the average number of postpaid accounts during the period, further divided by the number of months in the period.

**Average Revenue Per User ("ARPU")** - Average monthly service revenue earned per customer. Service revenues for the specified period divided by the average number of customers during the period, further divided by the number of months in the period.

Postpaid phone ARPU excludes postpaid other customers and related revenues.

**Service revenues** - Postpaid, including handset insurance, prepaid, wholesale and other service revenues.

**5. Cost of services** - Costs directly attributable to providing wireless communications and broadband services, including direct switch and cell site costs, such as rent, network access and transport costs, utilities, maintenance, associated labor costs, long distance costs, regulatory program costs, roaming fees paid to other carriers and data content costs.

**Cost of equipment sales** - Costs of devices and accessories sold to customers and dealers, device costs to fulfill insurance and warranty claims, write-downs of inventory related to shrinkage and obsolescence, and shipping and handling costs.

**Selling, general and administrative expenses** - Costs not directly attributable to providing wireless communications and broadband services for the operation of sales, customer care and corporate activities. These include all commissions paid to dealers and retail employees for activations and upgrades, labor and facilities costs associated with retail sales force and administrative space, marketing and promotional costs, customer support and billing, bad debt expense and administrative support activities.

**6. Net income margin** - Net income divided by Service revenues.

**7. Adjusted EBITDA and Core Adjusted EBITDA** - Adjusted EBITDA represents earnings before Interest expense, net of Interest income, Income tax expense, Depreciation and amortization, stock-based compensation and Special Items. Core Adjusted EBITDA represents Adjusted EBITDA less device lease revenues. Core Adjusted EBITDA and Adjusted EBITDA are non-GAAP financial measures utilized by T-Mobile's management, including our chief operating decision maker, to monitor the financial performance of our operations and allocate resources of the Company as a whole. T-Mobile historically used Adjusted EBITDA and T-Mobile currently uses Core Adjusted EBITDA internally as a measure to evaluate and compensate its personnel and management for their performance. T-Mobile uses Adjusted EBITDA and Core Adjusted EBITDA as benchmarks to evaluate its operating performance in comparison to competitors. Management believes analysts and investors use Core Adjusted EBITDA and Adjusted EBITDA as supplemental measures to evaluate overall operating performance and to facilitate comparisons with other wireless communications and broadband services companies because they are indicative of T-Mobile's ongoing operating performance and trends by excluding the impact of Interest expense from financing, non-cash depreciation and amortization from capital investments, non-cash stock-based compensation and Special Items. Management believes analysts and investors use Core Adjusted EBITDA because it normalizes for the transition in the company's device financing strategy, by excluding the impact of device lease revenues from Adjusted EBITDA, to align with the related depreciation expense on leased devices, which is excluded from the definition of Adjusted EBITDA. Core Adjusted EBITDA and Adjusted EBITDA have limitations as analytical tools and should not be considered in isolation or as a substitute for Income from operations, Net income or any other measure of financial performance reported in accordance with U.S. Generally Accepted Accounting Principles ("GAAP").

**8. Special Items** - Certain expenses, gains, and losses which are not reflective of our ongoing performance. Special Items include Merger-related costs (gain), net, network restructuring initiative costs (as discussed above), certain legal-related recoveries and expenses, Impairment expense, restructuring costs not directly attributable to the Sprint merger or UScellular acquisition (including severance), and other non-core gains and losses.

**9. Adjusted EBITDA margin and Core Adjusted EBITDA margin** - Adjusted EBITDA margin is calculated as Adjusted EBITDA divided by Service revenues. Core Adjusted EBITDA margin is calculated as Core Adjusted EBITDA divided by Service revenues. Adjusted EBITDA margin and Core Adjusted EBITDA margin are non-GAAP financial measures utilized by T-Mobile's management, including our chief operating decision maker, to monitor the financial performance of our operations and allocate resources of the Company as a whole.

**10. Net cash provided by operating activities margin** - Net cash provided by operating activities margin is calculated as Net cash provided by operating activities divided by Service revenues.

**11. Adjusted Free Cash Flow** - Net cash provided by operating activities less cash payments for purchases of property and equipment, plus proceeds related to beneficial interests in securitization transactions. Adjusted Free Cash Flow is utilized by T-Mobile's management, investors, and analysts of our financial information to evaluate cash available to pay debt, repurchase shares, pay dividends and provide further investment in the business.

Adjusted Free Cash Flow margin is utilized by T-Mobile's management, investors, and analysts to evaluate the company's ability to convert service revenue efficiently into cash available to pay debt, repurchase shares, pay dividends and provide further investment in the business.

**13. Net debt** - Short-term debt, short-term debt to affiliates, long-term debt (excluding tower obligations), and long-term debt to affiliates, short-term financing lease liabilities and financing lease liabilities, less cash and cash equivalents.

**14. Merger-related costs** include Sprint merger-related costs and UScellular merger-related costs.
