Rocket Lab (RKLB) Stock Could Trade At A Premium As Its 12x 3 Year Run Continues
Rocket Lab stock has delivered a very large 3 year gain, yet the latest valuation work sends a mixed message, with an intrinsic value estimate based on a Discounted Cash Flow (DCF) model pointing to upside while market multiples suggest the shares already trade at a premium.
- Rocket Lab has returned about 12x over the past 3 years, which puts extra focus on whether the current price still offers a reasonable margin of safety.
- Winning sizeable U.S. Space Force and other government contracts can support longer term cash flow expectations, while execution risk around new rockets and acquisitions may affect how quickly that cash flow shows up.
- On Simply Wall St's broader checks, Rocket Lab screens as a mixed picture rather than a clear bargain or clear overvaluation, with the stock judged attractively valued on 3 of 6 measures here.
The issue now is whether investors should treat the recent price as closer to the DCF intrinsic value or to the richer signal coming from market multiples.
Does Rocket Lab Look Undervalued on Cash Flow?
The Discounted Cash Flow (DCF) model estimates what Rocket Lab might be worth based on the cash it could generate for shareholders over time. For Rocket Lab, the model starts from the latest twelve month free cash flow, which was a cash outflow of about $370.5 million. It then assumes recovering and growing cash flows that turn positive and scale meaningfully over the next decade.
Based on these cash flow projections, the 2 Stage Free Cash Flow to Equity model arrives at an estimated intrinsic value of about $116 per share in dollar terms. With the current share price sitting well below that level, the DCF suggests the stock is trading at roughly a 31.3% discount, so the model indicates that Rocket Lab appears undervalued on a cash flow basis. The recent $397 million U.S. Space Force contract provides clearly defined work, which helps explain why the long term cash flow outlook in the model is relatively strong compared to today’s price.
On this DCF view, Rocket Lab stock screens as undervalued relative to the cash flows analysts expect it to produce over time.
Our Discounted Cash Flow (DCF) analysis suggests Rocket Lab is undervalued by 31.3%. Track this in your watchlist or portfolio, or discover 49 more high quality undervalued stocks.
Does Rocket Lab Look Pricey on Book Value?
P/B is a useful cross-check for Rocket Lab because investors are paying for a large base of space assets and acquired businesses that sit on the balance sheet. Rocket Lab currently trades on a P/B of about 13.7x, compared with an Aerospace & Defense sector average near 3.8x and a peer group average around 21.2x. That places the stock well above the industry but below the peer sample.
The model flags this as an expensive reading rather than a precise target. The gap indicates that investors are paying a high price for each dollar of Rocket Lab’s equity, while the business is still working through losses and heavy investment. Taken together with the very rich industry comparison, the P/B signal is more consistent with caution than with value.
On balance, Rocket Lab stock appears overvalued when judged against sector and peer P/B multiples.

The Bottom Line
Rocket Lab sits in a genuine valuation tug of war. The Discounted Cash Flow (DCF) view points to meaningful upside based on future cash flows, while traditional market multiples, especially P/B, flag the stock as overvalued relative to sector and peers. Broader checks sit in the middle, which keeps the focus on why the models diverge so sharply, from funding needs and capital intensity through to rich expectations already embedded in the price. The crux from here is whether Rocket Lab can turn heavy investment into reliable, scalable cash generation before sentiment or comparison with other space companies shifts against it.
