Firefly Aerospace Grows Q3 Revenue 259% and Builds a Record $1.7 Billion Backlog as Alpha Flight 8 Slips to 2027

Firefly Aerospace (NASDAQ: FLY) reported third-quarter revenue of $110.7 million on Tuesday, up 259% from $30.8 million a year earlier and ahead of Wall Street’s roughly $102 million estimate. The space and defense company also grew its backlog to a record $1.7 billion and raised the low end of its full-year guidance. However, its next Alpha rocket launch has moved to the first quarter of 2027, so investors now face a tradeoff between a strong spacecraft business and a later launch schedule.

Key Points

• Q3 revenue rose 259% to $110.7 million and beat consensus. This was Firefly’s second straight quarter above $100 million.
• Backlog reached a record $1.7 billion, up from $1.5 billion last quarter and $1.3 billion a year ago. Firefly booked more than $300 million in new contracts during the quarter.
• 2026 revenue guidance is now $440 million to $450 million, up from $420 million to $450 million. That lifts the midpoint to $445 million.
• Alpha Flight 8 moved to Q1 2027 at a national security customer’s direction, and Q4 guidance assumes no Alpha launches.
• Net loss narrowed to $94.2 million from $133.4 million a year earlier, while gross profit nearly tripled to $25.3 million.

Spacecraft Work Drives Firefly (FLY) Growth

Spacecraft generated $106 million of the quarter’s revenue, while launch contributed just $4.7 million. Firefly is currently running five Moon missions in parallel. It also finished expanding its spacecraft cleanroom, which can now assemble up to 12 lunar landers and orbital vehicles at the same time. A non-dilutive Texas Space Commission grant paid for the expansion.

Year-to-date revenue reached $309.2 million, up 203% from the same period in 2025. CEO Jason Kim said the company is “converting our pipeline and backlog into results,” and pointed to its lunar programs, the SciTec defense unit and its recent $1.3 billion deal with AST SpaceMobile (NASDAQ: ASTS).

A Deeper Contract Pipeline

Several wins pushed the backlog to its record. Lockheed Martin extended its agreement for up to 25 Alpha launches through 2031. In addition, Firefly signed its first European launch contracts with Sweden’s SSC Space, won a $94 million Space Force radar digitization award and received a third hypersonic test task order for Alpha. The company also joined NASA’s $10 billion CLPS 2 lunar program, which PMV covered on Monday.

Costs Climb as Next-Gen Rockets Advance

Firefly is still spending heavily. Operating expenses rose to $104 million from $94.3 million in the second quarter, mostly because of research and development on Alpha Block II and the larger Eclipse rocket. As a result, the operating loss widened to $78.7 million from $70.4 million in Q2.

Alpha Flight 8 Moves to 2027

The launch timeline remains the main open question. Flight 8, the debut of the redesigned Alpha Block II, is now scheduled for the first quarter of 2027. Management said a national security customer requested the change. Meanwhile, production continues: Flights 9 through 12 are in various stages of manufacturing, and Firefly describes Alpha demand as the most supply-constrained in its history.

Because Q4 guidance assumes no launches, the implied fourth quarter of $130.8 million to $140.8 million depends on spacecraft and software revenue alone.

Investor Takeaway

For Firefly Aerospace (NASDAQ: FLY), the quarter showed that the spacecraft business can carry growth while the launch business waits. FLY closed Tuesday at $23.70 and traded near $24 premarket, as a revenue beat and record backlog offset a guidance range that roughly matched consensus. The next catalysts are a successful Alpha Block II debut and continued conversion of the $1.7 billion backlog for investors following the PRISM Aerospace and Defense Index and the PRISM Space Index.
