If you are wondering whether Rocket Lab is priced fairly after its big run, you are not alone. This valuation review looks at that question in more detail.

Recent returns are mixed, with the share price at US$72.88, a 1.3% move over 7 days, 4.2% over 30 days, a 4.1% decline year to date, and a 295.7% gain over the last year, alongside a very large 3 year return and a 5 year gain of more than 5x.

Recent coverage has focused on Rocket Lab as a space and launch services player, with investors paying close attention to how the business model and funding environment relate to these sharp price moves. This has kept the stock firmly on the radar of those watching higher growth names and the risks that can come with them.

Rocket Lab currently has a valuation score of 1 out of 6. This suggests there is more to unpack in how different valuation methods treat the stock. It also sets up a closer look at standard models before finishing with a broader way to think about value that goes beyond just the numbers.

Rocket Lab scores just 1/6 on our valuation checks. See what other red flags we found in the full valuation breakdown.

Approach 1: Rocket Lab Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model takes projections of a company’s future cash flows, then discounts them back to today to estimate what the business might be worth right now. It focuses on cash the company could generate for shareholders over time, rather than accounting earnings.

For Rocket Lab, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections in $. The latest twelve month free cash flow is a loss of about $296 million. Analysts provide forecasts out to 2027, with free cash flow for 2027 projected at $84.9 million, and Simply Wall St then extrapolates further, with projected free cash flow of $295.1 million in 2035.

When all these projected cash flows are discounted back, the model arrives at an estimated intrinsic value of US$7.92 per share. Against the current share price of US$72.88, the implied gap is very large, with the DCF suggesting the stock is more than fully priced using these assumptions.

Approach 2: Rocket Lab Price vs Book (P/B)

For companies where profits are limited or volatile, price based metrics that do not rely on earnings, such as P/B, can be a useful way to cross check valuation. P/B compares the market value of the company with the accounting value of its net assets, which can be especially relevant for asset heavy or capital intensive businesses.

In general, higher growth expectations or lower perceived risk can justify a higher P/B ratio, while slower growth or higher risk tends to line up with a lower P/B. That is why it helps to compare a stock’s P/B to some reference points rather than looking at the number in isolation.

Rocket Lab currently trades at a P/B of 24.10x. This sits above the Aerospace & Defense industry average P/B of 3.96x and below the peer average of 26.50x. Simply Wall St also uses a proprietary “Fair Ratio” for the preferred multiple, which reflects factors such as earnings growth, risks, profit margins, industry and market cap. This Fair Ratio is designed to be more tailored than broad peer or industry comparisons because it adjusts for the company’s specific profile. In this case, the Fair Ratio for Rocket Lab is not available, so it is not possible to formally classify the stock as overvalued, undervalued, or about right on this metric alone.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Rocket Lab Narrative

Earlier it was mentioned that there is an even better way to understand valuation. On Simply Wall St you can use Narratives, where you write your view of Rocket Lab’s story, link that story to specific revenue, earnings and margin forecasts, and arrive at a Fair Value that is then compared to the current share price to help you decide whether the stock looks expensive or cheap on your assumptions.
