Rocket Lab (RKLB) Stock May Be 24% Undervalued As Space Force Deal Lands
Rocket Lab stock has delivered a very large 3-year gain while its valuation checks now show a split picture, with an intrinsic value estimate from a Discounted Cash Flow (DCF) model pointing to upside and market multiples suggesting the shares trade at a premium.
- Rocket Lab is up roughly 7x over the past three years, which puts extra attention on whether the current price still reflects a reasonable margin of safety.
- New U.S. Space Force contracts and progress on the Neutron rocket and Iridium acquisition can support long-term cash flow expectations, but the capital needs and execution risk around larger launch vehicles and integration may weigh on valuation if progress is slower or more costly than expected.
- The stock appears undervalued on the Discounted Cash Flow (DCF) estimate by about 23.6%, while market multiples lean expensive and the broader checks are mixed, with Rocket Lab passing 3 of 6 valuation tests on Simply Wall St, so it is neither a clear bargain nor clearly overpriced.
The key question is whether Rocket Lab’s current price better reflects the intrinsic value estimate or the more expensive signal coming from traditional market multiples.
Is Rocket Lab a Bargain on Cash Flow?
The Discounted Cash Flow (DCF) method estimates what Rocket Lab is worth today based on projected future cash the business could generate. For Rocket Lab, the latest twelve month free cash flow is a loss of about $300.8 million, so the model assumes a recovering trajectory from negative to positive cash generation over the coming years.
On those projections, the DCF points to an intrinsic value of about $83.68 per share, which is roughly 23.6% above the current share price and indicates the stock trades below this cash flow based estimate. The recent $266 million U.S. Space Force suborbital launch contract is one factor behind the relatively supportive cash flow expectations in the model despite the current cash outflow.
Overall, the Discounted Cash Flow valuation indicates Rocket Lab stock is priced below its estimated intrinsic value based on this model.

Does Rocket Lab Look Pricey on Book Value?
P/B is a useful cross check for Rocket Lab because the stock is still loss making, so book value can offer a clearer reference point than P/E. Rocket Lab currently trades around 16.9x P/B, which is far above the Aerospace & Defense industry average of about 3.7x P/B and slightly below the closer peer group average of about 19.0x.
This gap indicates that investors are paying a premium for Rocket Lab’s assets, even compared with other higher multiple peers, while traditional defense and aerospace companies trade at much lower book multiples. The market is effectively assigning a higher value per dollar of equity to Rocket Lab’s launch infrastructure, contracts and planned Iridium acquisition than to the sector overall. On this basis, the stock appears expensive on a P/B comparison.
On the P/B multiple alone, Rocket Lab appears overvalued compared with both the wider industry and its higher multiple peer group.

The Rocket Lab Narrative: What Would Justify Today's Price?
Simply Wall St Narratives pick up where Rocket Lab's valuation puzzle leaves off by spelling out which expectations for growth, margins and earnings would need to hold for the stock to be worth materially more or less than today's price, and they sit on the company's Community page. Each one treats Rocket Lab's fair value as a thesis about the business that can be revisited over time, rather than a single static number.
The Rocket Lab community is split between a wide runway for growth and a fragile story that depends heavily on one rocket.

The Bottom Line
Rocket Lab sits in a genuine valuation tug of war, with the Discounted Cash Flow (DCF) intrinsic value pointing to a 23.6% discount while rich market multiples flag the stock as overvalued. The gap largely reflects how differently cash flow models and P/B multiples treat heavy upfront investment, funding needs and current losses after a very large 3 year move. With broader checks coming through as mixed, the key question for you is whether Rocket Lab can turn its capital intensive launch and satellite roadmap into durable cash generation fast enough to justify today’s premium multiples, or whether the more cautious market view proves correct.
