Company Summary 

Lumos is on a mission to deliver lightning-fast, 100% Fiber Optic internet to the communities that need it most. After the merger of Lumos Networks and North State in 2022, we quickly rose to become a leading fiber internet provider. And as of April 1, 2025, we’ve joined forces with T-Mobile to launch T-Fiber—a joint venture that blends Lumos’ infrastructure expertise with T-Mobile’s national reach to bring fiber to more homes than ever before.

We currently connect over 475,000 homes, businesses, and multi-family buildings across nine states in the East and Midwest. With major growth in markets like Ohio, Alabama, Florida, and Georgia—and a shared goal of reaching 12 to 15 million homes by 2030—Lumos is playing a vital role in closing the digital divide.

Our Mission and Values

At Lumos, we are driven by our commitment to a brighter tomorrow. We take pride in being the first to deliver 100% Fiber Optic Internet for families, small businesses, and communities. We know the possibilities of tomorrow can’t be built on the infrastructure of yesterday. And when we deliver uninterrupted Internet and limitless capacity, we create new opportunities for everyone.

We believe that the past is over, and the future is fast. That’s why we are who we are: the disruptors of the status quo. Guided by our purpose and startup mindset, we step up, move first, and adapt as we go. Here, there’s no hierarchy, only hustle.

We are all servant leaders, confident in our purpose and humble enough to pay close attention to the details. We all have the power to help solve problems and find solutions for our customers and teammates - and we do - by putting people first and doing whatever it takes to build loyalty with our customers and within our team.

We’re passionate about our customers’ experience. Their futures don’t stand still, and neither do ours. We’ll never stop reinventing ourselves to meet our customers’ evolving needs - because we know that our work, delivering 100% fiber optic internet, truly changes people’s lives.
