Rocket Lab’s Shift to Space Systems Lifts Gross Margins as $2.2 Billion Order Book Builds

Rocket Lab's Q1 revenue hit $200.3M, with Space Systems leading at $136.7M. Backlog swelled to $2.2B. Despite insider selling, institutions increased stakes. Stock is up over 400% from lows but faces valuation concerns.

Rocket Lab’s transformation from a pure-play launch provider to a diversified space infrastructure company is gaining traction, with first-quarter results showing that its higher-margin Space Systems division has become the primary revenue driver. The company reported revenue of $200.3 million, up 63.5% year over year, with Space Systems contributing $136.7 million. The shift is reflected in a sharp improvement in adjusted gross margins, which climbed to 43% from 33.4% a year earlier.

The order book tells a similar story. Rocket Lab’s total backlog swelled to $2.2 billion in May, a sequential increase of 20.2%, fueled by new contracts for its Electron and upcoming Neutron rockets. The company signed 31 firm launch agreements for Electron and HASTE missions and five for Neutron, with the first-quarter volume already exceeding all contracts signed in 2025.

To support its growing production demands, Rocket Lab is deepening its vertical integration. The company recently agreed to acquire Motiv Space Systems for up to $60 million, adding key components for satellite manufacturing. This follows the milestone of producing the 1,000th Rutherford engine, underlining the scalability of its in-house operations.

Despite the operational momentum, the stock’s meteoric rise has prompted some insiders to cash out. CEO Peter Beck sold approximately $143 million worth of shares over the past six months, while CFO Adam Spice liquidated an estimated $110 million. Large institutional investors, however, have been adding to their positions. CloudAlpha Capital Management built a new stake in the double-digit millions, and Vanguard increased its holding by over 13% to roughly 47 million shares. Institutions now control 71.78% of outstanding shares, according to the latest filings.

The stock itself has been on a tear. It hit a 52-week high of €115.20 in recent trading, representing a gain of more than 400% from last summer’s low. Shares have risen 69.85% since the start of the year. The valuation has stretched to a price-to-sales ratio above 70, far exceeding the industry average.

That rich multiple has divided analysts. New Street Research has set a bullish price target of $150, but other market observers warn that a correction toward $100 is possible given the pace of the rally. The company’s market capitalization stands in the range of $73.6 billion to $76.7 billion.

Looking ahead, Rocket Lab has a busy schedule of near-term milestones. The annual general meeting is set for May 20, 2026, followed by the next Electron launch, dubbed ‘Viva La StriX’, on May 22 from New Zealand. That mission will deploy a radar satellite for Japanese Earth-observation company Synspective, marking the ninth launch for that constellation. The company is also working with NASA and Eta Space on the LOXSAT mission to test cryogenic propellant storage in orbit, a technology critical for future deep-space missions.

Later this year, the spotlight will shift to the maiden flight of the Neutron rocket, slated for the fourth quarter of 2026. The debut comes as SpaceX prepares for its own initial public offering in June, drawing Wall Street’s attention to the broader space sector. Rocket Lab is widely viewed as the most significant publicly traded alternative to Musk’s empire, controlling the small-satellite launch niche with its Electron vehicle. The combination of a record order book, expanding margins, and strategic acquisitions has positioned the company as a key player in the new space economy, even as its stock price tests the limits of investor patience.
