Frontier Communications has no plans to upgrade most of their legacy copper DSL internet customers this year, leaving customers in many markets stuck at speeds as low as 1-3 Mbps.

Frontier CEO Dan McCarthy told analysts in a late afternoon conference call Tuesday that around one million homes have access to Frontier’s 100 Mbps DSL service, and six million can sign up for DSL at or above 25 Mbps. McCarthy considers those customers valuable targets for marketing campaigns because most are not Frontier customers. For the rest of Frontier’s legacy copper areas that cannot access those speeds, Frontier will have little to offer in 2019.

“I don’t think you’re going to see us do a lot of significant copper upgrades this year,” McCarthy admitted. “Our big focus is really future proofing kind of the [California, Texas, and Florida] fiber markets. So, we’re spending the money to upgrade th[ose markets] to 10 Gbps capability.”

Frontier reported another quarter of poor results late yesterday, widely missing analyst expectations. Frontier’s share price lost 26.8% of its value overnight in heavy trading. Over the last 12 months, Frontier’s share price has dropped by 77%.

Analysts remain deeply concerned about Frontier’s customer defections, which have persisted for several years and show no signs of ending. Even more daunting, Frontier’s high debt levels are still a problem. A major tranche of Frontier’s debt comes due for repayment in 2022, and there are concerns Frontier may not be able to cover it, which could force the company into bankruptcy. In February, Bloomberg News ranked Frontier No. 1 on the list of deeply distressed debt issuers in North America.

While cable companies can count on quarterly boosts in the number of customers signing up for broadband, Frontier shareholders have become accustomed to reading about subscriber losses. The company lost 38,000 broadband subscribers in the last quarter, including in its fiber to the home markets. Most of Frontier’s losses are Charter Spectrum and Comcast’s gains. Frontier also reported landline and video customer losses.
