Rocket Lab backlog hit record $1.85B (69% sequential growth), with 74% from space systems and 26% from launch; SDA Tranche 3 award drives space systems backlog lumpy growth trajectory
Peter Beck· Rocket Lab· Space· 2026-02-27· about Rocket Lab (RKLB)
“We ended Q4 2025 with approximately $1.85 billion in total backlog and impressive 69% growth sequentially, primarily due to our recent SDA Tronche III Tracking Lair Contract Award... Space Systems' backlog in particular can be lumpy given the timing of these increasingly larger needle-moving program opportunities. But once awarded, they can significantly de-risk revenue growth for several years.”
Why it matters
Backlog composition (74% space systems) indicates shift in business mix toward higher-value, longer-duration contracts. However, lumpy awards create visibility and execution challenges.
Investment implication
37% of backlog expected to convert to revenue in next 12 months provides visibility. Investors should model conservative conversion rates (10-40-40-10 bell curve for large programs) rather than straight-line recognition. Execution on SDA Tranche 2 is critical proof point for Tranche 3 revenue recognition.
