2023 Annual Report

2023 A historic year
2023 was a historic year for T‑Mobile with record financial results, incredible business momentum, and significant returns for stockholders.
We delivered best-in-industry customer growth with more people than ever continuing to choose T‑Mobile—including large-scale enterprises and people across urban, suburban, and smaller markets. This growth was enabled by both the value we deliver customers and our industry-leading network, which has been recognized by independent experts as the best OVERALL network in the U.S.
We did it all while effectively completing the integration of the biggest, most successful telecommunications merger in the world.

We also added over 2.1M High-Speed Internet customers in 2023, our biggest growth year yet, and more than all our competitors combined. That’s what happens when customers get more value for their money on the leading 5G network in America.

Growth leadership that delivers
In 2023, not only did we deliver industry-leading customer growth—we also translated that into best-in-class financial growth—through strong execution, and all while accelerating and effectively completing the merger integration.
Our focus on driving profitable growth scored record results across many of the most critical metrics including Service Revenues (up 3% to $63.2B), Postpaid Service Revenues (up 6% to $48.7B), Core Adjusted EBITDA (up 10% to $29.1B), and Adjusted Free Cash Flow (up 77% to 13.6B). These results enabled us to execute on our substantial stockholder return model which delivered $14B to stockholders, including our first-ever quarterly dividend in Q4.
At a time when customers are winning from healthy competition that delivers more value and better networks,
As we look ahead to 2024, we expect yet another profitable year as we continue delivering on our unique combination of best network, best value, and best customer experiences, all while executing on our differentiated growth strategies to reach more people in more places. A win-win all around for customers, employees, and stockholders!

Our superpower is 5G
At the end of 2023,
There’s good reason why customers choose us.
On top of all that, our 5G dominance has put us in a position to completely transform the internet landscape. We’ve become the fastest-growing internet provider in the country, welcoming more home broadband customers in 2023 than Comcast, Charter, AT&T, and Verizon combined.
Our network now has a differentiated competitive advantage that complements our well-established value leadership. With the largest, fastest, and most awarded 5G network in the U.S., we’re committed to maintaining our network leadership in 2024 and beyond.

We also launched the first ever 5G network slicing beta program for developers with an initial focus on advancing video calling application technology.

Creating Brand Love
In 2023,
Last year marked 10 years since the Un-carrier movement was first launched. In 2013, we announced our first industry-rocking Un-carrier move—eliminating annual service contracts. And, through the steady drumbeat of big, bold moves that followed, we changed wireless for good and forced the competition to follow. In 2023, we continued shaking up the status quo. With Phone Freedom, we unveiled our Go5G Plus plan, giving customers the ability to upgrade their phone every 2 years (vs. the competitors’ 3-year wait), while also guaranteeing the same great device deals for both new and existing customers—now and in the future. Soon after that, we launched our premium Go5G Next plan, giving customers the freedom to upgrade every year.

Merger completed. History made.
In 2023 we effectively completed the biggest and most successful telecommunications merger integration in the world.Just three years later (and ahead of schedule), we’ve done what many said was impossible: effectively completing the integration of the biggest telecommunications merger in the world, and creating more competition, more choice, and more value for consumers and businesses. We realized synergies bigger and faster than even our own ambitious goals, accelerating 5G investment in the U.S. and delivering industry-leading growth and record low churn.
There is a reason why International Data Corporation (IDC), the premier global provider of market intelligence for the telecommunications industry, called this merger one of the most successful in wireless! At every step of our integration journey, we’ve always had a relentless focus on customers, which allowed us to bring competition and a 5G network to America that would not have ever been possible without this merger.
In 2023, the team drove unprecedented execution and completion of major integration milestones including billing migration to simplify frontline operations and customer care, and transitioning customers from device leasing to EIP and retail rationalization.
Most of all, we realized the dream of what this merger was always about—we smashed THE biggest pain point in the history of wireless by finally giving customers both the best network AND the best value.
Empowering our people and customers
In the ever-evolving telecommunications landscape,
As part of our innovative retail strategy, we continued transforming our approach to better serve customers in a digital-first era.

A force for good
As the Un‑carrier, we’re committed to using our network, scale, and resources for good while building a more connected, equitable, and sustainable future for all.


Bridging the Digital Divide With Purpose
Connectivity is essential in today’s digital-first world, so we’re doing our part to help close the digital divide. In 2020 T‑Mobile launched Project 10Million, a $10.7B initiative offering free internet connectivity to students who lack equal access. By the end of 2023, T‑Mobile connected nearly 6M students across the U.S. and invested $6.4B through Project 10Million and other education initiatives.
We also support Welcome.US, a digital equity initiative that connects immigrants and refugees with crucial supplies and services needed to start their new lives in the U.S. We have pledged to provide up to 200,000 lines of free talk and text service for refugees and partnered with Google to offer wireless devices.

Strength in Who We Are
We embed Diversity, Equity, and Inclusion (DE&I) into everything we do, from hiring and developing talent to embracing a diverse workforce that fuels our Un‑carrier spirit.
Our Equity in Action (EIA) plan serves as our five-year roadmap for prioritizing our people first and placing DE&I at the center of everything we do. By the end of 2023, we successfully met 80% of our 54 EIA promises and are on track to complete the remaining promises by 2025.
Recognized as a military-friendly employer, we’re dedicated to hiring and building lasting careers for those who have served, and by the end of 2023, we met our goal of hiring 10,000 veterans and military spouses.
And in recognition of creating an equitable workplace, T‑Mobile received a score of 100% on the Human Rights Campaign’s 2023-2024 Corporate Equality Index and on the Disability:IN 2023 Disability Index.
In 2023, T‑Mobile was accepted into the Billion Dollar Roundtable, a nonprofit that recognizes corporations for efforts to create supply chain diversity.

Prioritizing Our Planet
T‑Mobile was the first in U.S. wireless to set a goal to achieve net-zero emissions target (validated by the Science Based Targets initiative) across the company’s entire footprint by 2040.
In 2023, we continued to make progress toward net-zero emissions and have reduced total scope 1, 2, and 3 emissions by 30% since 2020. In recognition of this work, JUST Capital ranked T‑Mobile #31 overall on its 2024 list of America’s most JUST companies—and we ranked #1 in the telecommunications industry for environmental impact.
T‑Mobile also received an A- on our 2023 CDP Climate Change response, ranking number one out of 400 companies
Room to run
As we continue into the next chapter of the Un‑carrier, our mission remains the same: to be the best in the world at connecting customers to their world.
Our 2023 results are proof that it’s better over here at T‑Mobile—for customers, employees, and investors.
We’re winning share at record rates, and we will continue to take advantage of our momentum to keep growing and delivering profitable results—while acting as a champion for customers and the industry.
The pace of innovation right now is incredible and what customers want and need is changing rapidly. As we look ahead to 2024 and beyond, T‑Mobile will continue to deliver new, innovative, high-value experiences for consumers and businesses—all powered by the leading overall network in the country.
