Lumos Networks Preparing for Strong Bandwidth Demand from the Virginia Beach Undersea Cable Landing Site (“CLS”) into Richmond and Ashburn, VA

WAYNESBORO, Va., March 07, 2018 (GLOBE NEWSWIRE) — Lumos Networks Corp. (“Lumos Networks” or the “Company”), a leading fiber-based service provider in
the Mid-Atlantic region, announced that it plans to connect the Company’s fiber network to an existing building at 1632 Corporate Landing Parkway in Virginia Beach, Va. This building is currently being converted into a carrier-neutral co-location facility operated as Globalinx.

The Globalinx co-location facility is a short distance from the Cable Station Landing Station (“CLS”), which is operated by Telxius and located at 1900 Corporate
Landing Parkway. Consequently, upon the completion of connectivity into the Globalinx facility, Lumos Networks will be on-net and connected to the CLS.

“The necessary permitting and engineering efforts are underway and we expect to connect our fiber network to the Globalinx Co-location facility at 1632 Corporate
Landing Parkway during the back half of 2018,” said Timothy G. Biltz, CEO of Lumos Networks. “Once we have completed our short build of about ¼ mile into the
Globalinx facility, we will have the ability to route bandwidth traffic from the Cable Landing Station all the way to numerous data centers in Ashburn, Virginia. It is estimated that 70% of total global Internet traffic passes through the Ashburn area.”

Greg Twitt, Founder and President of Globalinx commented, “We are excited to partner with Lumos Networks to provide our customers direct access to Lumos
Networks’ expansive network from Virginia Beach to Ashburn, Richmond and beyond. Virginia Beach is becoming the new Continental Edge where the subsea
networks from around the world can handoff the international traffic directly and seamlessly to terrestrial networks at Globalinx colocation facility.”

Mr. Biltz continued, “In addition to Ashburn connectivity, we are seeing a sharp increase in data center and hyperscale activity in the Richmond Virginia metro market and they are seeking advanced fiber connectivity to both Ashburn and the CLS in Virginia Beach. Given our 500 mile dense fiber footprint in the Richmond metro area, we are poised to benefit from this explosive growth in content delivery.”

Currently, there are two undersea cables that are expected to be carrying traffic to the Virginia Beach CLS during 2018:

1) MAREA: jointly owned by Telefonica (Telxius), Microsoft and Facebook, is expected to become operational in the first quarter of 2018 and will connect the CLS with Spain;

2) BRUSA: 100% owned by Telefonica (Telxius) is expected to become operational in the back half of 2018 and will connect the CLS with Brazil

“We continue to see a growing pipeline of hyperscale providers, enterprises and carriers seeking both lit and dark fiber connectivity options from the Cable Landing Site in Virginia Beach to the extensive data center ecosystem in Northern Virginia, particularly in Ashburn Virginia,” said Joseph E. McCourt, Chief Revenue Officer of Lumos Networks. During the course of 2018 and beyond, we expect to utilize our extensive fiber footprint in the eastern half of the state of Virginia to meet the growing bandwidth needs of this diverse customer base.”

Warren Harris, Director of Virginia Beach Economic Development said, “Our goal is to make the City of Virginia Beach an International Connectivity gateway for the
mid-Atlantic and we are very pleased to see partners like Lumos Networks and Globalinx Data Centers are helping us realize that goal. We envision the convergence
of subsea and terrestrial networks to take place in Virginia Beach, eventually making it the diverse connectivity destination of the highly connected world.”
