Liberty Broadband Corporation experienced a sharp decline of approximately 26% on Friday, closely tracking the steep drop in Charter Communications. The sell-off was triggered by Charter's first-quarter earnings report, which revealed a larger-than-expected loss of broadband subscribers, intensifying concerns about the cable operator's growth trajectory and directly impacting the value of the pending all-stock merger between the two companies.
Subscriber Losses Exceed Expectations
Charter Communications, the parent company of Spectrum, reported losing 120,000 internet customers during the first quarter, significantly surpassing the 100,036 decline that analysts had anticipated, according to Visible Alpha data cited by Reuters. This marks a continuing challenge for the cable industry as fixed wireless access, or home internet delivered via mobile networks, increasingly siphons off customers from traditional cable providers.
The subscriber shortfall weighed heavily on Charter's financial results. First-quarter revenue dipped 1% to $13.6 billion, while adjusted EBITDA, a key profitability metric, fell 2.2% to $5.6 billion. Free cash flow also declined to $1.4 billion from $1.6 billion in the same period last year. Charter's shares closed down 26% at $179.04.
Merger Mechanics Amplify the Impact
For Liberty Broadband shareholders, the decline is particularly consequential because the merger agreement stipulates an all-stock transaction. Under the terms, each Liberty common share will be exchanged for 0.236 of a Charter Class A share. This structure means Liberty's stock price is directly tied to Charter's share performance, leaving investors with no cash option and little ability to decouple from Charter's market movements.
Following the sell-off, Liberty's Class A shares traded near $41.65, while Class C shares were just above at $41.67. The implied value of the 0.236 exchange ratio, based on Charter's closing price, worked out to approximately $42.25 per Liberty share, closely matching Liberty's own trading level and leaving minimal room for independent price action.
Broader Industry Pressure
The weakness wasn't confined to Charter and Liberty. Comcast shares also slid on Friday as the broader cable sector faced headwinds from aggressive competition by telecom giants such as AT&T and T-Mobile, which have been luring customers with wireless deals and broadband bundles.
During Charter's earnings call, CEO Chris Winfrey defended the company's position, expressing confidence in its long-term growth prospects. “We like cable as an investment. We think it's a great business,” he said, while also acknowledging that Charter remains interested in acquiring more cable assets if the price and terms are favorable. The company is currently pursuing the acquisition of Cox Communications' assets, having secured federal and state approvals but still awaiting sign-off from California. Charter aims to close that deal this summer and plans to introduce its Spectrum branding and pricing in Cox territories.
Execution Risks Loom
Liberty's exposure to Charter's performance is not limited to subscriber trends. Both companies have highlighted in proxy filings that any delays in closing the merger could expose Charter's stock to additional volatility, leaving Liberty shareholders uncertain about the final value of their payout. Charter itself has flagged the Liberty Broadband merger and the Cox transactions as risk factors, warning that deal conditions might not be met on schedule—or possibly not at all.
Liberty has already cleared a major hurdle by divesting GCI, its Alaska-based communications unit, on July 14, 2025. Post-transaction, Liberty's sole reportable segment is its equity-method stake in Charter, making the company a pure play on Charter's performance. As a result, Friday's decline snapped Liberty back into its traditional role as a leveraged proxy for Charter, with investor attention now squarely focused on Charter's ability to stem broadband subscriber losses, close the Cox deal, and keep the merger process on track.
