Globalstar (GSAT) Q4 2025 earnings review
Wholesale Engine Powers Record Year, But Legacy Drag Persists
Globalstar delivered a strong finish to a transformational 2025, beating revenue records with $273.0 million for the full year (+9% YoY) and hitting its 50% Adjusted EBITDA margin target. The Q4 narrative is defined by a 17% acceleration in service revenue, almost entirely bankrolled by its unnamed primary wholesale customer (widely known as Apple). However, the underlying unit economics tell a divided story: while Commercial IoT and wholesale capacity are surging, legacy retail segments (SPOT and Duplex) are steadily bleeding subscribers. Management is aggressively pivoting from groundwork to growth, but FY26 guidance of $280-$305 million implies a decelerating top-line growth rate of ~7% as the company waits for new technologies like XCOM RAN and two-way IoT to become material revenue contributors.
🐂 Bull Case
The company’s massive $550.4M CapEx spend in 2025 was effectively neutralized by $430.6M in infrastructure prepayments from its wholesale partner. Globalstar is building a next-generation C-3 satellite network with minimal balance sheet risk.
Commercial IoT hardware sales jumped 50% YoY in 2025, and average subscribers grew 6% YoY in Q4. The rollout of the RM200M two-way module significantly expands the Total Addressable Market into command-and-control applications.
🐻 Bear Case
Wholesale capacity services now account for nearly 69% of total service revenue. The company’s financial health is inextricably tied to the continued deployment and reimbursement schedules of a single partner.
Operating expenses (excluding non-cash items) jumped $8.8M in Q4. Investments in unproven terrestrial technologies like XCOM RAN are preventing the 50% Adjusted EBITDA margin from expanding despite higher overall revenue.
⚖️ Verdict: ⚪
Neutral/Bullish. The core wholesale business is a highly reliable cash engine funding a massive infrastructure upgrade. However, until XCOM RAN or two-way IoT proves it can move the needle independently, the stock remains a single-customer infrastructure play with a decelerating growth profile for 2026.
Key Themes
The Wholesale Capacity Juggernaut
Wholesale capacity is the undisputed engine of Globalstar. It generated $46.3M in 25Q4 (up 28% YoY from $36.2M in 24Q4). This segment benefits from performance bonuses and the steady reimbursement of network-related costs. This predictable revenue stream is what allows management to fund their $550M annual capital expenditure without destroying free cash flow.
Two-Way IoT Commercialization (Tech Innovation)
Globalstar completed the commercial rollout of the RM200M module, introducing two-way satellite IoT capabilities. This is a critical technological leap. Historically restricted to one-way asset tracking (pinging a location), two-way capability allows enterprise and industrial customers to send command-and-control signals (e.g., remotely shutting off a pipeline valve). This moves Globalstar into higher-ARPU, mission-critical enterprise use cases.
XCOM RAN Defense & Private 5G Ecosystem
The long-gestating XCOM RAN technology is finally showing tangible commercial ecosystem progress. Boingo completed a proof-of-concept to power next-gen private 5G deployments, opening doors to high-density environments like stadiums and airports. More importantly, defense contractor Virewirx (formerly XCOM Labs) won a $1.9M Phase II DoD contract utilizing Globalstar's platform. This validates the technology in high-capacity, RF-congested defense environments.
The Legacy Anchor Contradicts Growth Narrative
Management frequently highlights total subscriber growth, but specific data points contradict this rosy narrative. The legacy retail segments are a shrinking iceberg. SPOT average subscribers decelerated from 235.8K in 24Q4 to 215.6K in 25Q4. Duplex subscribers collapsed from 24.9K to 18.3K in the same period. The Commercial IoT segment is being forced to work overtime just to mask the churn in these legacy divisions.
Tariff Costs Hitting the Bottom Line (Macro)
The evolving global trade environment directly impacted Q4 results. Globalstar recorded a $1.1M expense in the cost of subscriber equipment sales related to tariffs on equipment imported and re-exported to foreign subsidiaries. These were previously logged as recoverable duty drawbacks but are no longer deemed probable of being refunded. While currently small, this exposes a vulnerability in their global hardware supply chain.
XCOM RAN Upfront Costs Constrain Margins
Adjusted EBITDA grew 7% in Q4, lagging the 17% overall revenue growth. The primary culprit is the $8.8M increase in operating expenses (excluding non-cash items). Management explicitly noted that they are incurring elevated personnel and development costs for XCOM RAN 'in advance of significant revenue.' Until this terrestrial product scales commercially, it will act as a margin ceiling.
Other KPIs
Accelerating significantly from $131.9M in FY24. This figure is highly adjusted, benefiting heavily from $45.0M in accelerated service payments from the updated services agreements. It proves the company can manage its aggressive $550M CapEx program without tapping traditional debt or equity markets, keeping the balance sheet healthy.
Reversing the massive -$50.2M loss from 24Q4. The dramatic YoY improvement is largely optical, driven by the absence of a $27.4M non-cash loss on debt extinguishment that occurred in late 2024, alongside favorable foreign currency remeasurements.
Stable. Down slightly from $417.5M at the end of 2024. Scheduled recoupments of $34.6M under the 2021 funding agreement were partially offset by a new $27.1M issuance in August 2025.
Guidance
Decelerating. The midpoint of $292.5 million implies a +7.1% YoY growth rate, stepping down from the 9% growth achieved in FY25. This suggests that near-term upside from the two-way IoT launch and XCOM RAN commercialization will be modest, or that legacy segment churn will offset early gains.
Stable. Matches the exact 50% margin delivered in FY25. Management's guidance indicates that any gross margin benefits from scaling wholesale services will be entirely reinvested into XCOM RAN and terrestrial network development.
Key Questions
XCOM RAN Revenue Inflection
You noted that XCOM RAN development costs are currently weighing on operating expenses in advance of significant revenue. At what specific milestone or timeframe in FY26 do you expect this product to cross the breakeven point and become accretive to EBITDA?
Legacy Churn Floor
SPOT and Duplex subscribers continue to decline at a steady clip. Is there a structural floor to this churn, and does FY26 guidance assume these segments eventually stabilize, or are you planning for a managed phase-out?
Supply Chain and Tariffs
With the $1.1M tariff charge realized in Q4 on re-exported equipment, what permanent supply chain routing changes or vendor shifts are being implemented in FY26 to ensure this doesn't become a recurring margin headwind for the hardware division?
