Rocket Lab Keeps Flying While Its CEO Warns the Space Trade Is Overheating

Rocket Lab flew its 95th mission and launched a new solar cell, but CEO Peter Beck flagged "very high" sector valuations as Neutron slips to Q4 2026.

Rocket Lab has spent the past few weeks doing what it does best: launching rockets and shipping hardware. On Friday the company completed its 16th Electron mission of 2026, lifting the "Happily Ever Faster" flight from Launch Complex 1 at 15:28 New Zealand time and placing an Earth-observation satellite for a confidential customer into a circular orbit 500 kilometers up. It marked the 95th launch in company history, and another commercial constellation operator mission is already booked for later this month.

The cadence has become routine. On September 2, Rocket Lab wrapped up its 94th Electron flight overall, carrying the StriX satellite for Japanese partner Synspective into a 575-kilometer orbit — the eleventh successful mission for that single customer. Reliability, at this point, is the product.

A CEO's Unusual Warning

Yet the loudest signal this week came not from the pad but from the executive suite. Founder Peter Beck said Thursday that the AI and space boom is "piping hot" and that sector valuations are "very high," cautioning that sentiment could turn at any moment. Coming from the head of one of the sector's most heavily traded names, the remark landed with unusual force — a founder effectively flagging froth in his own backyard.

The stock's recent trajectory gives that caution some context. Shares closed Thursday at EUR 53.40 and added 2.8% on Friday to trade around EUR 53.80, a modest bounce after a bruising 30-day stretch that saw the equity shed 22%. The paper now sits roughly 60% below its 52-week high of EUR 133.80, touched in May, while remaining well clear of the November low of EUR 32.60 — a reminder that the pullback began from elevated ground. Year-to-date, the shares are down about 11%.

Solar Cells, Defense Contracts, and a Second Leg to Stand On

Operationally, Rocket Lab is broadening its base beyond launch revenue. Production release for its IMM Apex space solar cell came on September 8. The germanium-free cell delivers an initial efficiency of 31.5% and weighs roughly 40% less than comparable triple-junction products, sidestepping a raw material whose supply is largely controlled by China. The underlying technology is already flight-proven — it powered NASA's Mars helicopter Ingenuity — and Rocket Lab solar modules supply more than 1,100 satellites in orbit, including the James Webb Space Telescope. Manufacturing runs out of Albuquerque, New Mexico, targeting output in the range of several hundred kilowatts per year.

The defense side is expanding in parallel. Earlier this month, Rocket Lab was selected for the US Space Force's Space Data Network consortium, backed by two delivery orders in August worth a combined USD 12 million in support of the so-called backbone network, with an in-orbit demonstration slated for 2027. A larger Space Force award worth USD 266 million already underpins the company's backlog.

Institutions Buy, Insiders Sell, and the Numbers Cut Both Ways

Capital flows reflect the split mood. The Arizona State Retirement System picked up roughly 267,700 shares in early September, and ARK Investment Management added across several ETFs on September 2, though reported share counts vary slightly between outlets. Berenberg initiated coverage on September 2 with a buy rating and a USD 83 price target, providing at least a one-day tailwind.

Working the other direction, CFO Adam Spice sold 140,157 shares in early September under a Rule 10b5-1 trading plan, after exercising options at USD 1.09 apiece — a payout of roughly USD 8.77 million. Such pre-scheduled disposals are standard fare for executives, but they tend to sit awkwardly beside upbeat headlines. Sector-wide headwinds add to the drag: Blue Origin's capture of a NASA Mars telecommunications network contract worth up to USD 700 million was read by market watchers as a sentiment hit across the space industry, a pointed reminder that Rocket Lab competes against far larger rivals.

The second quarter of 2026 illustrated the tension in the business itself. Revenue hit a record USD 234.1 million, up about 62% year over year, while free cash flow came in at negative USD 110.1 million, steeper than the prior quarter's negative USD 77.4 million — growth, in other words, still consumes capital. Backlog stands at USD 2.36 billion. Of roughly USD 2.4 billion in liquidity, USD 1.08 billion stems from an ATM equity placement tied to the planned acquisition of Iridium, a deal valued at around USD 8 billion.

Neutron Slips Again

For investors, the pivotal unknown remains the maiden flight of the Neutron rocket, now pushed to the fourth quarter of 2026. Until Neutron flies, Rocket Lab stays operationally anchored to Electron and its component business — including that new solar cell. The company keeps proving it can execute at pace; the open question is whether the market still has the patience to reward it.
