Cable One Stock Falls: Why Is the Penny Stock Lower After a Collapse in October?

Cable One (NYSE:CABO) shares are trading 4.22% lower at $4.88 on Wednesday, October 28, 2026, implying a prior close of about $5.10 (calculated). No new company release accompanied the move, which extends a steep October decline from a 52-week high of $167.36.

Cable One, based in Phoenix, supplies broadband, video and business data services under the Sparklight brand to residential and business customers across its footprint. Market capitalisation was about $25.7 million at the October 27 quote.

Mega Broadband Purchase Blocked: What Triggered the October Plunge?

Cable One signed a purchase agreement on January 3, 2026 to acquire the remaining equity of Mega Broadband Investments (MBI) after a put option was exercised on January 2. An 8-K signed October 2 moved the expected closing from October 1 to October 9 and said financing talks tied to the purchase had ended.

Shares fell about 9% to $12.03 on a media report that roughly $1.25 billion of first-lien financing was close, with trading halted several times. A federal court in New York then issued a temporary restraining order on October 9 after lender CoBank sued to block the deal, and shares dropped about 30% to $10.74 in early trading. The stock closed at $7.23 on October 16, down 14.64% that day.

Short Interest at 32.43% of Float: What Could It Mean for CABO?

The latest short-interest data, updated October 17, 2026, shows 1.48 million shares sold short, up from 842,479 a month earlier. That equals 26.01% of shares outstanding and 32.43% of the 4.55 million share float, with 3.95 days to cover.

With a float this small, short covering can amplify rallies, while continued selling can extend declines. A large shareholder also filed an exit notice on October 19 after selling shares between October 13 and 19 at weighted average prices that fell from about $13.02 to $6.07.

Second-Quarter Losses and $3.06 Billion in Debt: How Strained Is the Balance Sheet?

For the quarter ended June 30, 2026, reported August 6, revenue fell 8.4% to $348.9 million and adjusted EBITDA was $173.5 million, a 49.7% margin versus 53.3%. The net loss was $1.16 billion, driven by about $1.19 billion of pre-tax non-cash impairments and fair value adjustments. Residential customers fell by 17,000 to 870,000.

Gross debt was $3.06 billion, including about $1.66 billion of term loans, $550 million of revolver draws, $503 million of unsecured notes and $345 million of convertible notes. Cash was $166.2 million, with $700 million undrawn on a $1.25 billion revolver, and net leverage was 4.2 times.
