How Long Can Rocket Lab Stock Wait On Neutron?

Rocket Lab (RKLB) has fallen about 49% over the past three months, while signing the biggest launch contract in its history. The risk sits in the gap between those two facts. The threat is not on the demand side. It is that the company spends far ahead of Neutron, the rocket meant to turn its cash around, and Neutron has not flown.

Rocket Lab Has Never Sold This Much

Revenue in the second quarter of 2026 was a record $234 million, up 62% year over year. Backlog closed the period at $2.36 billion, and management says more than $1 billion of new contracts were signed in that quarter and the weeks after it. The largest launch contract is a $266 million award for up to 18 suborbital missions for the Space Force.

The wins are broadening by mission type too, expanding into space-based airborne threat tracking under a new Space Force program utilizing Rocket Lab’s Flatellite buses.

But Rocket Lab’s Heaviest Backlog Programs Earn The Least

GAAP gross margin was 36.1% in the second quarter of 2026. For the third quarter of 2026 management has guided it to 29% to 31%. The reason it gives is mix: higher-volume delivery on the SDA Tranche 2 and Tranche 3 satellite programs—which the CFO puts in the mid-30s, well below higher-margin Space Systems components that run north of 70 points—alongside lower-margin launch cadence and initial production ramp costs that pull the consolidated blend below the mid-30s floor.

Management expects the mix to turn beneficial beyond the third quarter. Even so, the biggest pieces of the backlog are the mid-30s kind, and Space Systems is scaling through its thinner half.

Rocket Lab’s Cash Flow Inflection Hinges On Neutron’s Post-Launch Horizon

Non-GAAP free cash flow was a use of $110.1 million in the second quarter of 2026 against $77.4 million in the first, and management expects it to stay elevated in the third quarter. The money goes into Neutron development and into building later Neutron vehicles.

The sequence management gives matters more than the burn itself. By the CFO’s account, on a stand-alone basis, adjusted EBITDA turns positive in the quarter after Neutron’s first successful test flight, and cash flow roughly 18 to 24 months after that. None of it starts without a launch, and the CEO has said the window for one before the end of 2026 is narrowing.

The cushion is smaller than the headline number. Of roughly $2.4 billion of cash and securities at the end of the second quarter of 2026, $1.08 billion raised via recent equity offerings is earmarked for strategic outlays—namely the pending Iridium transaction and other acquisition targets—leaving a much leaner buffer for ongoing operational burn.

The stock is still up 28.7% over the past twelve months against 19.1% for the S&P 500. At about 51 times trailing sales the stock is still priced as though the wait ends well. Watch the first Neutron flight. Every other date is measured from it.

So How Much Of Your Money Is Riding On One Launch Date?

The launch will not answer that for you. The answer depends on what else you hold, how long you can wait, and whether you would still hold if the date moved again.

Weighing that name by name is the job a portfolio does for you. Since its inception, our rule-based High Quality Portfolio has outperformed its benchmark, a blend of three major indices.
