Rocket Lab Breaks Space Force Records as Insider Sells and Sector Headwinds Sink the Stock

Rocket Lab's stock drops over 37% from highs amid insider selling and sector headwinds, even as revenue surges 63% and Neutron launch looms.

The gulf between mission execution and market reception is widening at Rocket Lab. On June 19, the company launched “Victus Haze” for the U.S. Space Force in just 16 hours and 42 minutes after receiving the official order — shattering the previous tactical responsive space record by more than ten hours and achieving military readiness in less than half the 72-hour target. CEO Peter Beck called the feat “transformative” for national security. Yet the stock has slumped more than 37% from its 52-week high of €133.80 hit in late May, trading recently at €84.10 — roughly 8.6% below its 50-day moving average.

Two separate forces are compounding the selloff. First, a relentless wave of insider selling has seen executives unload stock 130 times over the past six months with not a single purchase. CFO Adam Spice alone sold approximately $116 million worth of equity in that period, while COO Frank Klein offloaded around $24.8 million. Most recently, SVP and General Counsel Arjun Kampani transferred 88,000 shares at $107.98 each into an exchange fund on June 18, under a subscription agreement dated March 2026. Over the trailing 90 days, insider disposals totaled $76.4 million from 573,515 shares. While selling after a more-than-doubling year-to-date rally is normal, the complete absence of any insider buying makes the pattern stand out.

The second weight is sector-wide. SpaceX’s post-IPO slide of nearly 30% in three trading days has dragged down the entire space industry, hitting peers such as Redwire and Firefly as well. Investors are also wary of Rocket Lab’s $3 billion at-the-market equity program, which raises dilution concerns and has added to the skepticism. The Nasdaq-100 index inclusion — normally a catalyst for ETF inflows and institutional demand — fizzled into a classic sell-the-news event, with shares opening down more than 8% on June 22, the effective date.

Underneath the noise, the business is delivering. Q1 2026 revenue hit $200.3 million, a 63.5% year-over-year surge, and the backlog reached a record $2.2 billion — up 20% from the prior quarter. Major contracts include an $816 million Space Force deal, a $190 million hypersonic program with the Department of Defense, and a $24 million development contract for the Neutron upper stage. For Q2, management guided $225 million to $240 million in sales, about 12% above the consensus at the time.

The next pivotal catalyst is Neutron. Rocket Lab has filed with the FAA for a launch window running July 1 to December 31, 2026 — the first formal regulatory step — with the maiden flight penciled in for Q4. The Q2 earnings report, expected around August, will offer another key data point. If Neutron succeeds, the current valuation debate may quickly shift from concerns about insider sales and sector rotation to a fundamentally new growth narrative.
