Cable One Q3 2026 Revenue Plunges 11.7%, Posts $432M Net Loss

What happened

Cable One's third-quarter 2026 revenue fell 11.7% year-over-year to $332.2 million, accelerating from prior declines as competitive pressures intensified. The company swung to a net loss of $431.8 million from a profit of $86.5 million a year earlier, driven by a massive non-cash impairment charge that reflects reduced expectations for future cash flows. Even excluding the charge, the steep revenue decline suggests the subscriber base contracted more sharply than feared, likely outpacing management's earlier forecast of low-single-digit declines. This result directly undercuts the thesis that broadband losses were stabilizing; instead, the erosion appears to be worsening, with both units and pricing under pressure. The balance sheet implications are severe, as lower EBITDA will push leverage higher and complicate the 2028-2029 maturity wall and MBI obligations, collapsing the margin of safety that existed at the start of 2026.

Implication

The Q3 2026 results confirm that competitive erosion is accelerating, not stabilizing, with revenue down double digits and a massive impairment signaling management's own reduced outlook. With EBITDA likely falling below $600 million on an annualized basis, net leverage could exceed 5x, making the 2028-2029 debt maturities and MBI consolidation increasingly difficult to fund. The equity now resembles a deeply out-of-the-money call option on a turnaround that shows no evidence of materializing within the expected window. Even at seemingly cheap multiples, the lack of free cash flow and high refinancing risk argue against any new position, and existing holders should reassess the opportunity cost of remaining invested. Only a dramatic reversal in subscriber trends or a credible deleveraging plan would change this negative view.

Thesis delta

The prior 'wait' stance hinged on seeing either stabilizing broadband units or meaningful deleveraging within 12-18 months. The Q3 2026 results show neither, with revenue declining at a double-digit rate and a large impairment confirming a lower enterprise value. This shifts the probability toward the bear case, and the stock no longer offers a reasonable risk-reward even as a distressed option.
