Rocket Lab plans to shift Neutron spending from R&D into production inventory throughout 2026, with Q1 2026 expected to mark peak R&D spending; signals transition to manufacturing phase
Peter Beck· Rocket Lab· Space· 2026-02-27· about Rocket Lab, Neutron program (RKLB)
“we expect to see a shift in spending from R&D and into flight to inventory throughout 2026, which is an encouraging sign of progress as we move closer toward neutron's first flight and adjusted EBITDA positivity as a result. I'm optimistic that with the impressive strides we've made towards this milestone, and currently expect Q1 to mark peak neutron R&D spending.”
Why it matters
Shift from R&D to production inventory signals Rocket Lab expects first flight in Q4 2026 and is preparing for follow-on production. This increases capital intensity of the business in near term but supports gross margin expansion if production cadence accelerates post-first-flight.
Investment implication
Suppliers of production materials, components, and manufacturing services should expect accelerating orders from Rocket Lab through 2026-2027. Tooling and test equipment manufacturers should bid on Neutron-related contracts now. Negative free cash flow will remain elevated through 2026, supporting Rocket Lab's recent $280M equity raise.
