Rocket Lab USA rockets to record revenue, rising risks

Rocket Lab Usa, Inc. ((RKLB)) has held its Q1 earnings call. Read on for the main highlights of the call.

Rocket Lab Usa, Inc. delivered an upbeat earnings call that balanced record-breaking growth with candid acknowledgment of execution risks. Management highlighted all-time highs in revenue, margins, backlog, cash and booking activity, underlining strong demand for both launch and space systems. They also stressed that heavy Neutron investments, launch lumpiness and mix-driven margin pressure will keep near-term volatility elevated.

Record Revenue Clears New Milestone

Rocket Lab posted its first quarter above the $200 million mark, with Q1 revenue reaching $200.3 million. That represented 63.5% year-over-year growth and roughly 12% sequential growth, and management guided to a further step-up to $225 million–$240 million in Q2, implying about 16% quarter-on-quarter growth at the midpoint.

Margins Outperform on Solar and Launch Mix

Profitability surprised to the upside, with GAAP gross margin landing at 38.2% versus guidance of 34%–36% and non-GAAP gross margin at 43% versus 39%–41%. The beat was driven largely by strong performance in solar products and better absorption in the launch business, though management cautioned that margin mix will be less favorable in coming quarters.

Backlog and Bookings Hit New Highs

Total backlog swelled to about $2.2 billion, up roughly 20% sequentially and 108% year over year, underscoring durable demand. Launch orders represented around 41.5% of that total and Space Systems about 58.5%, with more than 70 launches in backlog after booking 31 Electron or HASTE missions and 5 Neutron contracts in the quarter.

Liquidity War Chest Strengthens

The company exited Q1 with approximately $1.48 billion in cash and equivalents and access to more than $2 billion in total liquidity. This cushion was bolstered by $450.4 million raised via an at-the-market program in the quarter, another $24 million in April, and various structured and convertible-related financings that collectively provide ample runway for Neutron and M&A.

Defense Wins and Program Scale-Ups

Rocket Lab notched several marquee defense wins, including selection for the Space-Based Interceptor program under the Golden Dome initiative with Raytheon. The company also secured a $190 million order for 20 HASTE launches and confirmed a multi-launch Neutron contract combining five Neutron flights and three Electron flights, the largest contract in its history.

Vertical Integration Through Targeted M&A

Management continued to push vertical integration, closing the acquisition of Mynaric to expand its European footprint and entering a definitive deal to buy Motive Space Systems. Several other bolt-on deals added in-house optics, propulsion and subsystems capabilities, all aimed at tightening cost control, scaling production and de-risking supply chains.

Electric Propulsion and Neutron Progress

On the product front, Rocket Lab unveiled its ‘GA’ electric propulsion thruster and set up a 200-unit production line, with initial units already delivered to customers. Neutron development advanced as well, with refinements to the first-stage tank, AFP-built components on the floor, successful stage separation tests, Archimedes engine hot-fires, thermal protection integration for reusable fairings and construction of a landing barge ahead of a first launch targeted later this year.

Profitability Metrics Trend the Right Way

Adjusted EBITDA loss improved to $11.8 million, well ahead of guidance for a loss of $21 million–$27 million and signaling better operating discipline. GAAP EPS loss narrowed to $0.07 from $0.09 in the prior quarter, while non-GAAP free cash flow use improved to $77.4 million from $114.2 million, even as Neutron and M&A spending continued.

Launch Cadence Builds Operational Momentum

Operationally, the company has already flown eight missions this year and expects to surpass last year’s launch record, with an eye on achieving its 100th launch later in the year. The Electron factory is designed for around 52 launches annually, and management indicated that only modest capital expenditure would be needed to further scale capacity.

Launch Revenue Volatility Emerges

Despite strong year-on-year growth, Launch Services revenue fell 16.1% sequentially to $63.7 million due to fewer missions in the quarter. This highlighted that launch-related revenue and margins will naturally exhibit quarter-to-quarter lumpiness, even as long-term demand and backlog trends remain robust.

Margin Headwinds from Space Systems Mix

Non-GAAP gross margin ticked slightly lower sequentially and management guided Q2 GAAP gross margin down to 33%–35% from 38.2% in Q1. The pressure stems from a growing mix of large Space Systems contracts, such as SDA tranches, which carry lower margins and from newly acquired businesses like Mynaric that initially operate at lower profitability.

One-Off Operating Expense Spike

GAAP operating expenses rose to $132.5 million, above prior guidance of $120 million–$126 million, but the increase was driven by a one-time stock-based compensation charge tied to the cancellation of RSUs held by Peter Beck. Management positioned this as a temporary GAAP impact rather than a structural escalation in the cost base.

Cash Burn and CapEx Remain Elevated

The company used $50.3 million of cash in GAAP operating activities and reported non-GAAP free cash flow use of $77.4 million in the quarter. Capital expenditures remain high as Rocket Lab continues to invest in Neutron development, a landing barge and new launch pad infrastructure, and management signaled that negative free cash flow will persist in the near term.

Neutron Reusability Carries Execution Risk

While Neutron’s first launch is targeted for later this year, management acknowledged that critical high-risk campaigns remain, including stage separation trials, engine relight during reentry and barge landing operations. The company aims to achieve reusability by the second flight, but timing and performance depend heavily on data and outcomes from the inaugural mission.

Headcount Shift Toward Production

Total headcount climbed to 2,778, up 176 quarter on quarter, with production-related staffing increasing by about 250 as programs transition from R&D to manufacturing. R&D headcount fell by about 70, reflecting the shift, but these changes raise near-term payroll and production costs as major programs ramp toward volume.

Adjusted EBITDA Still in the Red

Despite better-than-expected results, adjusted EBITDA remained negative and management guided to another loss in Q2, between $20 million and $26 million. Continued investments in Neutron and recently acquired businesses are expected to weigh on reported profitability even as revenue and backlog grow, delaying a clean break into sustained positive EBITDA.

Forward Guidance Emphasizes Growth and Investment

For the second quarter of 2026, Rocket Lab expects revenue of $225 million–$240 million, with GAAP gross margin of 33%–35% and non-GAAP gross margin of 38%–40%. Operating expenses are forecast at $138 million–$144 million on a GAAP basis and $120 million–$126 million non-GAAP, with net interest income of $12.5 million, an adjusted EBITDA loss of $20 million–$26 million and elevated negative free cash flow likely to persist into the fourth quarter as Neutron scaling continues.

Rocket Lab’s earnings call painted the picture of a company in aggressive build-out mode, pairing record revenue, margins and backlog with heavy investment and execution risk on its next-generation rocket. For investors, the story is one of strong demand, deep liquidity and growing strategic relevance offset by near-term losses and volatility as Neutron and new acquisitions work their way toward scale.
