To The Moon

On Friday 6 November, Firefly Aerospace ( $Firefly Aerospace Inc.(FLY)$ ) announced a deal worth more than $1.3 billion with AST SpaceMobile ( $AST SpaceMobile, Inc.(ASTS)$ ): 36 rocket engines, a licence for AST to build those engines itself, and three years of engineering support. Firefly closed up 29.19% and AST up 6.10%, per The Wall Street Journal. The easy read is "big order, buy the stock". The read that matters is stranger: a satellite operator just paid a launch company to stop being its launch supplier, because access to orbit — not demand for its service — is holding its constellation back. Is Firefly now a propulsion merchant, or has it handed a customer its crown jewels?

What Was Actually Signed

Strip out the adjectives and the contract has four moving parts: 36 engines over three years — 27 Miranda and nine vacuum-variant Vira, enough for AST's first three rockets — a licence for AST to manufacture the engines itself, three years of engineering support, and full IP ownership retained by Firefly. Both companies describe the arrangement as "non-competitive by design", per Firefly's release.

The payment is where the structure gets interesting. AST will pay more than $1.3 billion in a mix of cash and AST Class A common stock, with the shares subject to various lock-up periods, according to the release. Via Satellite's reporting breaks the schedule down further: roughly $400 million in cash up front, 10 million to 14 million shares, $250 million on delivery of engines for the first three rockets, and $250 million over three years for engineering support services.

Add those itemised pieces and you get $900 million — against a headline of "more than $1.3 billion". The $300 million-plus gap is not broken out. That is a reminder that "deal value" in aerospace press releases is a ceiling assembled from milestones, not a purchase order.

Why AST SpaceMobile Stopped Renting Its Ride to Orbit

AST SpaceMobile is not buying engines because engines are cheap; it is buying them because its launch supply broke. Blue Origin's New Glenn is out of service, and it lost one of AST's commercial satellites in April, placing it into the wrong orbit on the first commercial New Glenn mission, Via Satellite reported. AST had expected 45 BlueBird satellites in orbit by year-end.

That is the thesis: a direct-to-device constellation is a manufacturing-and-launch race, and AST was winning the first half while losing the second. In July it began studying vertical integration and a capital raise to fund partnerships or acquisitions. It had more than $3.7 billion in cash at the end of June — the reason it can buy its way out of a supplier failure at all.

The vehicle that came out of that process is called Blacklift: roughly a 20-ton rocket designed to carry five BlueBird satellites per launch, with missions targeted to begin in late 2028, according to Via Satellite. Firefly supplies the propulsion; AST assembles the rocket and eventually manufactures the engines under licence. Abel Avellan, AST's chief executive, framed the choice as scarcity: Firefly is "one of a few companies in the United States with a proven liquid engine of this scale".

Firefly Is Repricing Itself as a Propulsion Merchant

For Firefly, the shift is bigger than the cash. The company has been judged as a launch provider — only as good as your last flight and your next slip. This contract makes it a supplier of a component other people's rockets cannot fly without, paid partly up front for the privilege.

The engineering case is real, and it is what the licence is priced against. Miranda is a 230,000-pound-force-thrust engine that has completed more than 175 hot-fire tests for more than 4,200 seconds, including a flight-like test at 110% of rated performance that ran 20 seconds beyond the nominal 206-second flight duration, per Firefly. Both Miranda and Vira scale from the company's flight-proven Reaver and Lightning engines, using Firefly's patented tap-off cycle.

The money goes to capacity, not distributions: more test bays at the Rocket Ranch in Briggs, Texas, long-lead materials bought ahead of schedule, and a larger engineering headcount, per the release. Firefly chief executive Jason Kim described it as supercharging production so the company can "build and test faster across our launch portfolio".

The asymmetry matters. Firefly keeps its IP and keeps selling engines to government and commercial launch customers. AST gets a licence to manufacture, not the patent portfolio — the difference between selling a factory and selling a copy of the drawings, and the detail that decides whether this is a one-off or a franchise.

Bull Case

1. The cash arrives before the work does. About $400 million up front, per Via Satellite, funds capacity in a business where capacity is the constraint — money Firefly does not have to raise.

2. Firefly keeps the IP and keeps selling. The release is explicit that Firefly retains full ownership. AST is a licensee, not an owner — the same engine can be sold again.

3. AST's decision validates launch scarcity. A satellite operator building a 20-ton rocket to secure five satellites per launch does not expect the launch market to clear by 2028.

4. The deal is a public reference customer. A named, listed counterparty committed to Firefly's engine architecture for three rockets shortens the sales cycle with every other constellation operator.

5. There is a dated catalyst. Firefly's Q3 2026 earnings call is at 5 p.m. ET on Tuesday 10 November, with the agreement on the agenda — the first chance to see how management books the revenue.

Bear Case

1. Part of the payment is someone else's stock. AST pays in cash and AST Class A shares subject to lock-ups; Firefly's "$1.3 billion" contains equity price risk it cannot hedge until the lock-ups lapse.

2. The customer's balance sheet is not infinite. The deal is worth about 35% of the $3.7 billion AST reported at June 30 — my arithmetic on Via Satellite's figure — on top of Blacklift programme costs. More AST capital raises are plausible, and dilution would hit the stock component of Firefly's consideration.

3. The licence caps the annuity. AST gets a perpetual licence to manufacture the engines, per Via Satellite. After the first three rockets, Firefly's largest engine customer can become its newest competitor for its own design.

4. Firefly's own rocket competes for the same resources. Test bays, engineers and long-lead materials are finite; work for AST is work not done on Firefly's own vehicles — and speed is a promise, not a schedule.

5. Nothing flies until late 2028. Both companies are asking investors to underwrite three years of execution across two organisations.

Strategic Slam

$Firefly Aerospace Inc.(FLY)$ — the stock is no longer a pure launch bet. It is a launch company with a contracted propulsion business attached, funded partly in advance, IP still on its own books. The condition that matters is the 10 November call: if management quantifies how much of the $1.3 billion is recognised in 2027 versus 2028, the re-rating has a floor; if not, the market is left holding a press release.

$AST SpaceMobile, Inc.(ASTS)$ — buying schedule control is the right call for a constellation let down by a launch provider. It also converts a satellite operator into a rocket developer — a harder business with a longer feedback loop. Watch cash: $3.7 billion at June 30, now funding a rocket as well as a constellation.

Verdict

This is a genuine business-model event for Firefly, and a rational, expensive admission of failure by AST SpaceMobile. The market underweights the licence: Firefly sold manufacturing rights to its most important engine while keeping ownership — cash today, control tomorrow. It overweights the headline number, a ceiling built from milestones and stock. After a 29% session, the easy money has been made; what remains is a three-year execution trade, and the next honest data point is the 10 November call, not the press release.

Key Takeaways

1. Firefly will deliver 36 engines — 27 Miranda and nine Vira — plus a manufacturing licence and three years of support to AST SpaceMobile.

2. The announced payment schedule itemises $900 million of a headline "more than $1.3 billion"; the rest is undisclosed milestones.

3. AST is buying launch independence after New Glenn went out of service and one of its satellites was lost to a wrong orbit.

4. Firefly keeps its engine IP and can sell the same design to other customers; AST gets a perpetual licence to build it.

5. The commitment equals roughly a third of AST's June cash pile, and the first Blacklift flight is not targeted until late 2028.

The open question for the comment section: if a customer will pay $1.3 billion to own your engine design, is that proof your technology is scarce — or the first sign that your best customer is becoming your competitor?
