SharkWater Trading  •  Space Desk • ASTS and FLY AST SpaceMobile Buys Its Own Rocket Engine License From Firefly for $800 Million November 7, 2026 Bottom Line Up Front AST SpaceMobile (NASDAQ: ASTS) said on November 6, 2026 that it will build its own 20-ton reusable rocket, Blacklift, on engines licensed from Firefly Aerospace (NASDAQ: FLY). The license costs about $800 million upfront: $400 million in cash plus 10 to 14 million Class A shares priced off a forward VWAP. A supply deal adds $250 million for engines on the first three launches and $250 million for three years of engineering support. The total is $1.3 billion, which matches Firefly's headline. The release names no financing source for ASTS and gives no price for the shares. Both gaps close in the next six days: Firefly reports Tuesday, and ASTS unveils the rocket Thursday. What the 8-K Exhibit Says The source is Exhibit 99.1 to an AST SpaceMobile Form 8-K, datelined Midland, Texas, November 6, 2026. AST will build a reusable launch vehicle to put up to five BlueBird satellites per flight, starting in late 2028. The company calls it the final step of its end-to-end vertical integration. Outside launch contracts for more than 100 BlueBird satellites between 2027 and 2028 stay in place. Piece of the deal Amount Terms as filed Engine license (Miranda and Vira) about $800M upfront $400M cash plus 10 to 14M Class A shares, set by forward VWAP Engine supply $250M Engines for the first three Blacklift launches Engineering services $250M Over three years Total (my arithmetic) $1,300M Firefly headline: more than $1.3 billion Source: AST SpaceMobile 8-K Exhibit 99.1, dated Nov 6, 2026. The $400M share value is implied by subtracting cash from the $800M total. The exhibit gives no per-share price, so the dollar value of the shares is not determinable from it. Firefly's own release body was not read; only its headline was seen on its investor page. The Part the Release Skips The exhibit does not say how ASTS pays the $400 million in cash, and it does not mention a capital raise. I could not find a primary source that does. The only equity element in the document is the 10 to 14 million shares handed to Firefly. Treat anything you read about a larger raise as unconfirmed until it shows up in a filing. Timing matters too. First launch of Blacklift is late 2028. Satellites that need to fly in 2027 and 2028 ride on other companies' rockets. The new rocket does not help the near-term deployment schedule. It is the difference between chartering a boat and buying the shipyard. Owning the yard ends the dependence on other captains, but the first hull does not float for two years. Why the Date Stack Matters Date Event Source Mon Nov 9 Rocket Lab earnings, carried from earlier scans Not re-verified today Tue Nov 10, 5:00 PM ET Firefly Q3 2026 results call Firefly investor page Thu Nov 12 ASTS unveils Blacklift in New York, webcast ASTS 8-K exhibit Thu Nov 12 Nebius Q3 results, call 8:00 AM ET Nebius release, Oct 30 Dates as listed on the issuers' own pages when read on Nov 7, 2026. Firefly's call lands first. The question for that call is how much of the $400 million cash and the $500 million of supply and services is recurring revenue versus a one-time license payment. A perpetual license is paid once. The supply and services lines are the only parts that repeat. Market Backdrop Friday was a repair day. Per CBS News (updated 4:32 PM EST, press report, not exchange data), the S&P 500 rose 0.3 percent to 7,377, the Nasdaq Composite rose 1.1 percent and the Dow fell 0.5 percent. The October jobs report showed 165,000 new jobs against an estimate of 65,000, with unemployment at 4.1 percent, per Fox Business and CBS. The Cboe VIX read 25.64 on its November 6 page stamped 9:15 PM ET, down 9.01 percent from a 28.18 prior close. I could not verify how ASTS or FLY traded on the news. The Bull Case Control of launch. ASTS owns a perpetual engine license and a dedicated engine plant, which removes a bottleneck on its own constellation. Real money for Firefly. $400 million cash upfront plus $500 million of contracted supply and services is hard revenue, not a memorandum of understanding. Dilution is capped on paper. The share component is 10 to 14 million Class A shares, a stated range rather than an open-ended issuance. The Bear Case Unfunded cash outlay. No financing source is named for the $400 million cash plus $500 million of supply and services. Late and unproven. First Blacklift flight is late 2028 and it adds a rocket program to a company still deploying satellites. Value is unpriced. The VWAP formula leaves the real cost of the share component unknown until it settles. The SharkWater Take On the paper alone, Firefly got the better deal. It collects cash now and keeps a revenue line for three years, while ASTS signs up for a rocket program that cannot fly until late 2028 and names no way to pay for it. I am not taking a side on either stock this weekend. I do not know how either one traded Friday, and I do not know where the $400 million comes from. If Firefly's call and the Thursday unveiling answer the funding question, I will revisit. If they dodge it, the vertical integration story is a bill with no payer. Tight lines.
