What happened: Rocket Lab shares fell more than 6% in after-hours trading on November 9 after the company reported a wider-than-expected quarterly loss, despite record revenue and rising Neutron demand. Key numbers: Q3 revenue $267.83 million, up 73% year over year, above estimates of about $257 million. Why it matters: Higher research and development and operating expenses weighed on profitability, raising investor concerns about the cost of scaling the business. The Neutron maiden flight slipped to 2027 after defects were found in the first-stage tank's forward dome.
