We enable connectivity for millions of people and organizations across the country with our communications infrastructure—helping bridge the digital divide and propel economic, technological and social advancement in communities. That’s why Environmental, Social and Governance (ESG) efforts continue to be a key part of who we are—down to our business model.

With this extensive reach, we have a unique opportunity to make a real impact, like we’ve done by investing ~$10B in communications infrastructure for low-income areas.1 As we grow, we will add to our strong foundation and continue to operate conscientiously with our teammates, environment and communities in mind.
