Rocket Lab Corporation (RKLB) Down 17.7% Since Last Earnings Report: Can It Rebound?

RKLB has dropped 17.7% since its September 2026 earnings report, lagging the S&P 500 despite strong operational results. The stock decline creates a potential entry point as the company posted Q2 2026 revenue of $234.1 million, up 62% year-over-year, while narrowing losses and beating expectations.

The company ended the quarter with a record backlog of $2.36 billion and total liquidity of $2.4 billion. Management raised Q3 guidance following the results. Analysts responded by lifting estimates 21.43% and assigning RKLB a Zacks Rank #2 (Buy) rating, which typically indicates potential for above-average returns. The company continues to underperform on VGM scores, which measure value, growth, and momentum metrics.

The divergence between operational performance and stock price creates tension heading into the next earnings cycle. Revenue growth at 62% year-over-year and a backlog exceeding $2.3 billion suggest demand remains robust, while the post-earnings selloff may have discounted near-term execution risks or broader market rotation.
