$RKLB is a real space business, but the stock is already priced like Neutron works

Rocket Lab is one of the few public space companies where the business is already real. Revenue exists, launches are happening, government customers are involved, and the backlog is large enough to matter.

That still does not make the stock cheap.

The company reported about $602M of revenue in 2025, up 38% YoY, and ended the year with roughly $1.85B of backlog. It also completed 21 Electron / HASTE launches in 2025 with a 100% mission success rate, according to the company's FY2025 release.

Those numbers separate Rocket Lab from the weaker "space is the future" names. This is not just a story stock with a deck.

The valuation is where the argument gets harder. Based on the May 5 close, RKLB was around a $45B company. Against about $602M of 2025 revenue, that is roughly 75x trailing sales.

At that level, the market is not just paying for Electron launches. It is paying for Rocket Lab to become a much larger space infrastructure company.

That distinction matters. Electron gets the attention because rockets are easy to understand, but small launch alone is not enough to support this kind of valuation. Launch is operationally difficult, scheduling is messy, delays happen, and pricing power is not unlimited.

The more important part of the story is Space Systems. Satellites, spacecraft components, solar, mission services, and government space work make Rocket Lab more than a launch provider. That is the part that can make the company look closer to a space infrastructure platform instead of a niche rocket company.

The positive case is that Rocket Lab already has execution credibility. The SDA satellite contract helps because it shows the company can win serious government work beyond small launch. The backlog also gives revenue visibility that many public space names do not have.

Neutron is the real swing factor. If Neutron works commercially, Rocket Lab moves into a much bigger launch market and the current valuation becomes easier to justify. If Neutron slips, underperforms, or takes too long to commercialize, the stock has much less room for error.

That is the core tension.

Rocket Lab can be a strong company and still be an expensive stock. At roughly 75x trailing revenue, the market is already assuming strong execution across Space Systems, backlog conversion, margin improvement, and Neutron progress.

The next report is important because Q1 2026 revenue guidance is $185M-$200M. The revenue number matters, but the cleaner signal is whether Space Systems keeps scaling and whether margins start moving in the right direction. Neutron commentary will probably matter just as much as the quarter itself.

Current read: RKLB deserves a premium versus most public space names because the company has real operating traction. But the stock is already priced for a lot of success.

Strong company. Demanding stock.
