Shares of Cable One (NYSE: CABO) plummeted 13.66% in Thursday's after-hours trading following the release of the company's disappointing first-quarter 2025 financial results. The dramatic sell-off came as the broadband communications provider reported earnings that fell significantly short of analyst expectations.

Cable One's Q1 net income saw a steep decline, dropping to just $2.607 million from $37.350 million in the same period last year, representing a 93% decrease. The company's earnings per share (EPS) came in at $0.46, far below the analyst consensus estimate of $8.41. Revenue for the quarter also missed the mark, totaling $380.601 million compared to the expected $386.9 million, and down 5.9% from the previous year.

The company's performance was further marred by a decrease in its residential data subscriber base and revenue. Cable One reported a 2.3% year-over-year decline in residential data subscribers, while residential data revenue fell by 4.5%. These metrics are particularly concerning for investors, as they indicate potential challenges in the company's core business segments.

Adding to the negative sentiment, Cable One's adjusted EBITDA of $202.712 million also fell short of the $206.7 million analyst estimate. This combination of missed targets across multiple financial metrics likely contributed to the sharp decline in the stock price, as investors reassessed their outlook on the company's near-term growth prospects and profitability.
