Rocket Lab Corp A (RKLB) surged 6.40% to $85.39 in a volatile session driven by a series of high-impact announcements and growing investor interest in the space sector. The stock opened with a modest 0.7% gap up and climbed steadily throughout the morning, reaching a session high of $85.42. The move coincided with reports of a major contract with Viasat to build a satellite bus for the U.S. Space Force and progress on the Iridium acquisition, which has bolstered investor sentiment.

What Happened

Rocket Lab announced that Viasat has selected it to build a satellite bus for the U.S. Space Force’s Protected Tactical SATCOM-Global program. The contract, disclosed on May 22, includes the development of one of the first small geostationary satellites, along with five years of operations and cybersecurity support. The company also reported progress on its Iridium acquisition, signaling strategic momentum. Additionally, Cathie Wood’s ARK Investment Management purchased 292,000 shares of Rocket Lab on the same day, further fueling market optimism. Rocket Lab also launched eight satellites under a $143 million deal with MDA Space for the Globalstar constellation, marking a key milestone in its contract fulfillment.

What The Data Shows

The stock has traded within a 52-week range of $37.57 to $151.00 and is currently up 15% year to date. Despite a trailing twelve-month revenue increase of 45.8%, Rocket Lab remains unprofitable with a net loss margin of -26.9%. The stock’s beta of 2.63 indicates high volatility relative to the broader market. Intraday volume of 3.0 million shares was significantly below the 3-month average. Unusual options activity included a notable $315,000 call premium, reflecting speculative positioning. Insiders have sold $351.0 million in shares over the last 90 days, with no insider purchases reported.

What To Watch

Rocket Lab has no scheduled earnings date in the immediate outlook. Investors should monitor the breadth of coverage and any further developments in its Iridium acquisition and satellite contracts.
