Kampani Arjun, SVP & General Counsel at Rocket Lab (RKLB), has been a persistent seller of the company’s stock over the past several months, with no corresponding open-market purchases. Across 40 Form 4 filings, Arjun has disposed of approximately $34.5 million in RKLB shares, all coded as open-market sales (“S”). The most recent activity, clustered in late May and June 2026, shows a heavy concentration of selling: a single transaction on June 18 accounted for $9.5 million, while a series of eight separate sales on May 28 ranged from roughly $30,000 to $988,000, totaling about $3.5 million. Earlier in the same week, sales on May 27 and May 26 added another $10.2 million and $4.1 million, respectively. The pattern extends back to early March, with multiple sales on March 4 and March 2 totaling roughly $3.1 million combined.
Notably, the only non-sale transaction in the recent window was a grant (“A”) on March 24, valued at $0, which represents compensation rather than a discretionary buy. There are no recorded purchases, option exercises, or acquisitions in the data, underscoring a one-directional bias toward liquidation. The dollar amounts vary widely, from small sales of a few thousand dollars to the eight-figure June transaction, suggesting a mix of routine position trimming and larger block disposals. While the filings do not indicate whether these sales were executed under a pre-arranged 10b5-1 plan, the sheer frequency—24 sales in the recent period alone—points to an ongoing, deliberate reduction of the insider’s stake in Rocket Lab.
