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.
