In 2025, Rocket Lab’s share count surged to reflect a remarkable 173.9% gain over the prior year, driven by an accelerated launch cadence and stronger-than-expected revenue growth. The company completed 20 Electron rocket missions last year, up from 12 in 2024, achieving a mission success rate of 98%. This ramp-up in launch frequency translated into annual sales growth of 62%, as payload deliveries to both commercial and government customers expanded rapidly.

Rocket Lab solidified its position in the small- and medium-lift market by securing four new launch service agreements valued at more than $1.1 billion combined. Major wins included multi-launch deals with a leading defense agency and a satellite constellation operator. As of year-end, the company’s contracted backlog reached $2.8 billion, a 45% increase versus the previous twelve months, ensuring visibility into revenue streams through 2028.

Investor enthusiasm has pushed Rocket Lab’s valuation multiple toward historical highs, reflecting expectations of continued market share gains. However, the forward revenue multiple now exceeds 20 times consensus estimates, raising questions about downside risk if growth slows. Key factors that could influence the stock’s trajectory in 2026 include successful maiden flights of the Neutron vehicle, margin expansion through production efficiencies, and progress toward a broader space systems business beyond launch services.
