Unlocking Value Through Separation: GCI Liberty and Liberty Broadband Post-Spinoff

The spinoff of GCI Liberty from Liberty Broadband on July 14, 2025, marks a pivotal moment for two companies now positioned to capitalize on distinct growth trajectories. By separating its Alaska-based telecommunications monopoly (GCI Liberty) from its Charter Communications stake (Liberty Broadband), the parent company has created two standalone entities with clearer strategic identities and investment opportunities. This move not only simplifies operational complexity but also unlocks value in two underappreciated sectors: regional broadband expansion and merger arbitrage. Below, we dissect the implications for investors.

The Spinoff Mechanics: A Clean Break

The separation was finalized after securing regulatory approval from Alaska's Regulatory Commission on June 27, 2025—a critical hurdle for GCI Liberty's independence. Shareholders of record as of June 30 received 0.2 shares of GCI Liberty's Series A (GLIBA), B (GLIBB), and C (GLIBK) common stock for each share of Liberty Broadband held. GLIBA and GLIBK began trading on Nasdaq on July 15, while GLIBB launched on the OTC Markets days later. The split ensures Liberty Broadband retains its Charter stake, now free to accelerate its merger with Charter's Cox Communications acquisition, while GCI Liberty pursues its $4.7 billion fiber rollout in Alaska.

GCI Liberty: A Monopoly in Motion

GCI's dominance in Alaska's telecom market—serving over 200 communities—is a rare asset in an era of fragmented broadband competition. With $4.7 billion allocated to fiber expansion, the company aims to modernize infrastructure in one of the U.S.'s most underserved regions. Unlike national players like AT&T or Verizon, GCI faces minimal competition, enabling pricing power and steady cash flows. Its network investments align with federal broadband subsidies, such as those under the Infrastructure Investment and Jobs Act, which could further subsidize rural deployment.

Why GLIBA/K is Undervalued:
GCI's enterprise value relative to its addressable market is striking. With ~90% market share in Alaska's broadband and wireless sectors, its valuation lags behind peers like Frontier Communications (FTR) or Windstream (WIN). Post-spinoff, GCI's standalone financials—unburdened by Liberty Broadband's Charter stake—may attract investors seeking exposure to a “last-mile” infrastructure play. The $4.7 billion investment, if executed, could transform Alaska into a high-margin, low-growth-risk operation.

Liberty Broadband: Merger Arbitrage Meets Simplification

With GCI now independent, Liberty Broadband's sole focus is its Charter stake, which stands to benefit from the accelerated merger with Cox Communications. The spinoff's timing was no accident: separating GCI likely streamlined regulatory approvals for Charter's deal, as Liberty Broadband's reduced complexity made it an easier partner.

Investors in Liberty Broadband (LBRDA) now benefit from two catalysts:
1. Merger Arbitrage: Charter's merger with Cox is expected to close by year-end, with LBRDA holders entitled to a premium upon completion.
2. Focus on Core Assets: Liberty Broadband's reduced portfolio removes distractions, allowing management to optimize its Charter stake, which already represents ~85% of its asset value.

Strategic Benefits of Separation

The split achieves two critical goals:
1. Operational Clarity: GCI can now pursue its fiber rollout without cross-subsidizing Charter's national ambitions, while Liberty Broadband's singular focus on Charter's merger reduces strategic misalignment.
2. Reduced Complexity: Regulatory scrutiny and investor confusion over Liberty Broadband's dual mandates (GCI vs. Charter) are eliminated, potentially improving credit ratings and access to capital for both entities.

Investment Thesis: Two Plays for Two Markets

• GCI Liberty (GLIBA/GLIBK): Investors seeking exposure to a “moaty” regional telecom with high growth in underserved markets should consider GLIBA/K. The shares offer a rare pure-play on rural broadband expansion, with upside from federal subsidies and organic growth.
• Liberty Broadband (LBRDA): Arbitrageurs should monitor LBRDA's convergence toward Charter's merger premium. With Charter's stock trading at a discount to its implied value post-Cox integration, LBRDA's upside is binary but substantial.

Risks and Considerations

• Regulatory Hurdles: While Alaska's approval was secured, future state or federal rules on telecom pricing or infrastructure could pressure GCI.
• Merger Delays: Charter's Cox deal faces antitrust scrutiny, and delays could compress LBRDA's premium.
• Valuation Pressures: GCI's reliance on federal funding and Alaska's small population cap long-term growth, while LBRDA's success hinges entirely on Charter's execution.

Conclusion: A Strategic Divorce with Clear Winners

The GCI Liberty spinoff is a masterclass in value creation through separation. GCI emerges as a disciplined infrastructure bet in a monopolistic market, while Liberty Broadband becomes a merger vehicle with a clear endgame. For investors, both stocks represent asymmetric opportunities: GLIBA/K for growth in a niche sector and LBRDA for short-term arbitrage. As the dust settles post-spinoff, these companies are now positioned to deliver on their distinct, unburdened visions.
