From Rockets to Space Infrastructure: More Than Just a Rocket Company

When we think about space companies, it is easy to think about rockets first.

Rocket Lab is increasingly becoming a different kind of business.

Today, only around 25% of its revenue comes from launch.

The other 75% comes from Space Systems, designing satellites, manufacturing components, and supplying critical infrastructure.

And that distinction matters.

The rocket is only one part of the story:

Rocket Lab’s first major product was Electron, a small satellite launch vehicle.

The idea was fairly simple.

Not every customer needs a giant rocket.

Companies such as Planet Labs may only need to put relatively small satellites into orbit. Paying for excess capacity on a large rocket doesn’t always make sense.

Electron was built specifically for this market.

It gave Rocket Lab a dedicated small-launch platform at a time when most of the industry was focused on heavy rockets.

The company also introduced reusability in 2023.

And the numbers suggest that the economics are improving.

Rocket Lab conducted around 10 launches in 2023, with gross margins of roughly 11%.

In 2024, launches increased to 16 and margins improved to around 27%.

By 2025, with roughly 20–21 launches, gross margins moved towards 35–40%.

That is the part we find interesting.

As launch frequency increases, the economics are getting better.

More launches mean better utilisation, more experience, and the ability to spread fixed costs across a larger number of missions.

Then comes Neutron:

But Electron alone isn’t enough to build a truly large space business.

This is where Neutron comes in.

Neutron is Rocket Lab’s medium-lift rocket, designed to compete more directly with Falcon 9.

The rocket has faced delays, moving from 2024 to 2025 and now to 2026, so execution remains the biggest question mark.

The opportunity, however, is significant.

Neutron is expected to target a launch price of roughly $50 million, compared with around $62–67 million for Falcon 9.

And there is already demand.

Rocket Lab has secured five government contracts even before Neutron has flown.

That gives us some confidence that there is a real market waiting for the rocket.

But there is an obvious problem.

SpaceX.

Falcon 9 has years of flight experience and an enormous advantage in reusability.

So even if Neutron launches successfully, competing with SpaceX on cost and reliability will not be easy.

The more interesting business is Space Systems:

This is where Rocket Lab starts looking much less like a traditional rocket company.

Space Systems has become the majority of revenue, and its margins have improved dramatically.

Margins have gone from roughly 16% in 2021 to around 40% in 2025.

At the same time, the backlog has grown from around $1.8 billion to $2.2 billion in just one quarter.

And the customer base isn’t dependent on one company.

Government and commercial customers are both contributing to the business.

This is important because satellite infrastructure can create more recurring and predictable revenue than launches.

Instead of simply getting paid every time a rocket flies, Rocket Lab can make money from the components, satellites, and systems that go into the broader space ecosystem.

The rocket gets the attention. The Space Systems business may be what makes the company financially interesting.

But the stock has already figured out the story:

And this is where we need to be careful.

Rocket Lab is still not profitable.

Neutron remains an execution risk.

We have already seen how sensitive the stock can be to delays. A payload-approval issue in 2025 triggered a roughly 40–50% drawdown in the stock.

And after rising around 300% over the past year, expectations are clearly high.

The market isn’t valuing Rocket Lab as a small rocket company anymore.

It is valuing it as a future end-to-end space infrastructure company.

That distinction is important.

If Neutron works, Space Systems continues to scale, and margins keep improving, the opportunity could be much larger than what Electron alone represents.

But if Neutron gets delayed again, or SpaceX continues to widen its cost advantage, the valuation can come under pressure very quickly.

Our takeaway:

Rocket Lab is probably one of the more interesting space companies outside SpaceX.

The reason isn’t simply that it has rockets.

It is because the company is building across the entire space stack: launch, satellites, components and defence infrastructure.

The Space Systems business is already showing better margins and a growing backlog, while Neutron could open up a much larger market.

The question is whether Neutron can execute well enough to justify the expectations already built into the stock.

And that is something we would be watching very closely.
