FLY Stock Upgraded to $35 on AST SpaceMobile Major Rocket Deal, as Jefferies Supports Firefly Aerospace
Firefly Aerospace (FLY) shares rose 36% after a $1.3B deal with AST SpaceMobile (ASTS) for rocket engines and tech. FLY will supply 36 engines, receive $800M upfront. Jefferies reiterated a $35 target. FLY's Q3 earnings are due Nov 10, with expected revenue of $103M and negative EBITDA.
How this was made

The 30-second read
Why it matters
The deal provides upfront cash and stock consideration plus delivery and engineering payments, which the article says Firefly will use to expand hiring, equipment, and engine-testing capacity. It also sets up near-term catalysts: FLY’s Nov 10 Q3 earnings and AST’s Nov 12 Blacklift unveiling.
Market read
Traders can reassess near-term momentum and earnings expectations for FLY based on a large, specific engine-supply agreement and a reiterated analyst target, with additional program headlines expected next week.
What to watch
Execution and manufacturing cost risk remain, and the article flags development and scheduling risk for Blacklift, which can cap how much the market extrapolates from the deal.
Background
Firefly Aerospace has been in a prolonged decline since May, and the article frames the Nov 6 rally as an attempt to reverse that trend after the AST SpaceMobile agreement.
Ticker impact
Firefly Aerospace shares surged after a three-year, $1.3B AST SpaceMobile deal for 36 rocket engines plus engineering support and tech licensing.
Likely continued upside bias while traders price in deal funding and engine IP validation, with volatility around the Nov 10 earnings report.
The article provides deal size, engine scope, funding components, and a near-term catalyst (earnings) tied directly to FLY.
AST SpaceMobile is the counterparty to the three-year agreement, paying for engine deliveries and engineering services for its Blacklift heavy-lift rocket.
Likely modest positive read-through as the market treats the engine supply agreement as incremental program validation.
The article details AST’s payments and licensing path, but the main trading focus is the FLY stock reaction and FLY earnings.
Market effects
Reinforces demand visibility for launch-vehicle engine suppliers and highlights the role of engine IP and manufacturing licensing in heavy-lift programs.
No specific regional market linkage beyond US-listed space/defense supply chain sentiment.
Supports broader satellite broadband and launch-capacity narratives, though the article is company-specific rather than a global policy or supply shock.
Counterpoint
The contract value is described as potential, not already-earned revenue, so the stock rebound may fade if near-term financials do not translate into measurable progress.
