Rocket Lab Insiders Cash Out $18 Million Despite Record $2.2 Billion Backlog

Rocket Lab finds itself caught in a peculiar moment — a record $2.2 billion order book coexists with an $18 million insider sell-off that has helped wipe 21% off the stock in a single week. The company’s pivot from pure-play launch provider to vertically integrated defense contractor has never looked stronger on paper, but the share price tells a different story.

Between late May and early June, four insiders executed a flurry of 18 separate transactions offloading stock worth roughly $17.9 million. The largest single sale hit $5.96 million on May 28. On June 1, the selling accelerated: director Alexander Slusky cashed out 60,000 shares for around $8.96 million, while president Marvin Bradford Clevenger sold 3,500 shares worth about $513,000. Chief operating officer Frank Klein and general counsel Arjun Kampani also trimmed positions, all via pre-arranged Rule 10b5-1 trading plans. Not a single insider bought during the period — a pattern that unnerves retail investors.

The exits landed in an already brittle sector environment. A rocket explosion at Blue Origin rekindled fears about satellite launch schedules, while the SpaceX IPO roadshow — targeting a valuation around $1.75 trillion to $1.8 trillion — triggered a broad reassessment across space equities. Elon Musk disputed the lower-than-expected valuation reports, but the uncertainty lingered. With that kind of capital rotating toward the sector’s biggest name, Rocket Lab’s stock took a direct hit.

The timing is especially stark because the underlying business continues to strengthen. Rocket Lab’s space systems division posted $136.7 million in Q1 revenue, more than double the $63.7 million from its launch segment. The company has successfully transformed itself from a rocket-launch specialist into a satellite manufacturer and defense supplier. On the military side, it passed the system requirements review for the Space Development Agency’s TRKT3 program in May — a contract worth around $816 million for missile-warning and tracking satellites. Added to the existing Transport Layer Beta program (roughly $515 million), Rocket Lab’s SDA commitments now exceed $1.3 billion. Its total backlog has swelled to a record $2.2 billion.

Should investors sell immediately? Or is it worth buying Rocket Lab?

That backlog helped earn the company a rating upgrade from Seeking Alpha on Wednesday, which moved to “Buy.” The analysts argued that Rocket Lab now looks more like a stable defense contractor than a speculative launch stock, thanks to the recurring revenue embedded in its space-systems business. The US Space Force has also selected Rocket Lab for the Space Based Interceptor Demonstration program, developing counter-hypersonic missile systems. The high switching costs in these national-security contracts offer a durable competitive moat, even as new players eye the medium-lift segment.

Institutionally, the picture is mixed. During Q1 2026, 541 institutional investors increased their stakes while 363 reduced them. Capital World Investors sold roughly 8.96 million shares — a 55.3% cut — yet Capital International Investors added 6.7 million shares, and BlackRock boosted its position by 4.9 million shares, a 14.8% increase. The analyst consensus from S&P Global stands at “Buy” with an average price target of €103.91, though the range spans €60 to €150, reflecting deep disagreement about valuation for a company that, despite strong top-line growth, still operates at a loss.

The stock recently traded at €100.00, up 1.21% on the day but nursing a 21.38% weekly loss. It remains 20.81% above its 50-day moving average of €82.78 and a hefty 63% above the 200-day line at €61.35. The relative strength index sits at 49.1 — neutral territory — suggesting the selling has temporarily exhausted itself. But the 30-day annualized volatility stands at 131%, warning that calm may be fleeting.

All eyes now turn to the Neutron rocket, whose first flight slipped to the fourth quarter of 2026 after a structural failure during a pressure test in January. A successful launch would reset the narrative around Rocket Lab’s growth trajectory, but the SpaceX roadshow runs through June 11, keeping the entire sector on edge. Meanwhile, the company’s record backlog provides a foundation, but it has yet to convince the insiders — or the broader market — to hold steady.
