Gogo (GOGO) Q4 2025 earnings review
Heavy Investment Cycle Concludes; Focus Shifts to 2026 Inflection
Gogo closed out a transformative 2025 by launching its long-awaited 5G and Galileo (LEO) networks. Q4 revenue grew 67% YoY to $230.6M (or +3% pro-forma, accounting for the Satcom Direct acquisition), while FY25 Free Cash Flow hit $89.2M, successfully reaching the high end of prior guidance. However, Q4 net income dropped to -$10.0M due to a hefty $10M litigation accrual and -$4M convertible note write-down. Free Cash Flow briefly reversed into negative territory (-$4.9M) as the company aggressively built inventory ahead of the 2026 Galileo hardware ramp. Guidance for 2026 projects modest ~2% revenue growth but a solid 12% acceleration in Free Cash Flow as R&D and CapEx phase out.
🐂 Bull Case
The 3-year heavy investment phase is over. 5G activated in January 2026, and Galileo shipments are accelerating (158 in Q4, targeting ~900 in 2026). FCF is set to accelerate 12% as CapEx requirements collapse.
MilGov revenue jumped 34% YoY. A newly won C-130 approval unlocks a 1,000+ airframe TAM, proving Gogo's multi-orbit strategy is highly attractive to defense customers demanding network redundancy.
🐻 Bear Case
Total Air-to-Ground (ATG) aircraft online dropped 9% YoY. While management insists this is a managed upgrade cycle, failing to migrate these legacy 'Classic' users to LTE/5G before network switch-offs will permanently destroy high-margin recurring revenue.
A sudden $10M litigation settlement accrual and an ongoing $8.4M quarterly legal expense severely impacted Q4 profitability. Margins are also pressured by the equipment mix shift, which operates at near-cost.
⚖️ Verdict: ⚪
Neutral to Bullish. 2025 was a transition year successfully executed. While Q4 optics are clouded by litigation and inventory build costs, the operational milestones—launching 5G, scaling LEO, and integrating Satcom Direct—set up a highly visible, cash-generative 2026.
Key Themes
Galileo LEO & 5G Rollout Set for 2026 Acceleration
The highly anticipated new product cycle is finally active. Gogo shipped 158 Galileo HDX/FDX units in Q4 (+80% QoQ) and expects to ship nearly 900 in 2026, aiming for 700 online by year-end. 5G commenced service in January 2026, targeting 400 aircraft online this year. Management expects combined new product activations to act as a significant high-margin service revenue driver over the next decade.
Legacy ATG Fleet Bleed is a Race Against Time
Total ATG Aircraft Online (AOL) is decelerating, down 9% YoY to 6,402. Gogo is racing to upgrade its remaining ~1,100 'Classic' legacy customers to AVANCE or C-1 units before the upcoming LTE network cutover. While AVANCE units grew 8% YoY, they haven't entirely offset the legacy churn. Gogo assumes Classic AOL will reach zero by Q4 2026, making conversion execution critical.
Military & Government Evolving from Niche to Core
The Satcom Direct acquisition has fundamentally transformed Gogo's MilGov exposure. MilGov revenue grew 34% YoY to $31.2M in Q4. Recent strategic wins, including a $33M Space Force contract and C-130 hatch mount approvals (1,000+ airframe TAM), show that government agencies highly value Gogo's multi-orbit redundancy (PACE protocol). This segment offers a stable, high-value growth engine to offset business aviation cyclicality.
Litigation and Legacy Write-Downs Crush Q4 Profits
Net Income reversed into negative territory (-$10.0M) due to a sudden pile-up of non-operational costs. This included a $10M litigation settlement accrual, an ongoing $8.4M quarterly litigation operating expense, and a $4M hit on a convertible note investment. Equipment margins also turned negative in Q4 due to legacy hardware write-offs. Investors need visibility into when these legal headwinds will fully abate.
Pricing Power adjustments ahead of 5G
ATG ARPU declined 3% YoY to $3,378. Management confirmed this was largely due to price reductions on unlimited plans designed to bridge customers toward the new $5,500/month 5G unlimited plans. While it compresses near-term yields, it's a strategic move to lock in customer real-estate prior to the 5G service switch-on.
Other KPIs
Reversing. FCF dropped from $30.6M in Q3 to negative $4.9M in Q4. Management flagged that this was an intentional $17.1M working capital build-up (inventory) specifically to secure hardware for the impending 2026 Galileo rollout. Full-year FCF still hit the high end of their promised $60-$90M range at $89.2M.
Accelerating. Up 104% YoY and 15% sequentially. ATG equipment shipments hit an all-time record of 472 units. This reflects massive dealer activity pushing C-1 box swaps and AVANCE upgrades ahead of the 2026 LTE cutover.
Net leverage ratio stood at 3.3x, within management's target range of 2.5x - 3.5x. With roughly $250M in total liquidity (including a $122M undrawn revolver), management signaled a priority to use 2026 excess cash to refinance debt and eventually return capital to shareholders.
Guidance
Stable. The midpoint of $925M implies roughly 1.6% growth over FY25's $910.5M. The growth rate is optically low because 2026 will suffer the remaining roll-off of legacy ATG and narrowband revenue, which is masking the underlying growth of the new Galileo and 5G product ramps.
Stable. The midpoint of $208M is slightly below FY25's actual $217.8M. This incorporates $3M in strategic investments and $5M in ongoing litigation expense, combined with a heavier mix of lower-margin equipment sales early in the year as the new fleets are seeded.
Accelerating. Midpoint implies 12% YoY growth from FY25. Driven directly by the collapse of strategic investment spend (Galileo OpEx dropping from $10M to $1.5M, 5G CapEx halving) and robust run-rate synergies from the Satcom Direct acquisition.
Decelerating significantly. This low number is achieved by an anticipated $45 million reimbursement from the FCC Reimbursement Program, marking the final major phases of the LTE ground network build.
Key Questions
Classic Fleet Conversion Mechanics
Of the roughly 1,100 legacy 'Classic' aircraft remaining, what is the exact conversion rate to C-1 or AVANCE versus outright churn to competitors like Starlink?
Litigation Runway
With an $8.4M quarterly expense and a $10M settlement accrual in Q4 alone, what is the projected timeline to resolve the ongoing litigation, and is the $5M guided for 2026 a firm ceiling?
GEO ARPU Cannibalization
As customers upgrade large jets to multi-orbit LEO/GEO setups, how rapidly do you expect standalone GEO ARPU to compress, and at what blended rate do you expect the multi-orbit ARPU to stabilize?
Working Capital Normalization
Given the $17M inventory build in Q4, at what point in 2026 will inventory levels peak and working capital become a tailwind for Free Cash Flow?
