• If you are wondering whether Rocket Lab's current share price lines up with its underlying value, it helps to separate the story from the numbers and look at what recent price moves and valuation checks are really saying.
• The stock closed at US$105.05, with the price down 8.4% over the past week and 10.5% over the past month, yet still up 38.2% year to date and 284.0% over the last year. These moves can shift how investors think about both upside potential and risk.
• Recent news around the broader "new space" sector and attention on competitors has kept Rocket Lab in focus for investors, especially as capital markets reassess which space companies might justify higher valuations. Coverage has also highlighted how space infrastructure, launch services and satellite platforms tie into long term themes, giving more context to the sharp gains already on the board.
• In that context, Rocket Lab currently records a valuation score of 0 out of 6. The next step is to look at how different valuation approaches assess the stock today and, later in the article, consider an even broader way to think about what "fair value" might mean for you.

Rocket Lab scores just 0/6 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, or DCF, model estimates what a stock might be worth by projecting future cash flows and then discounting them back to today using a required return. It is essentially asking what all those future dollars are worth in present terms.

For Rocket Lab, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The company currently reports trailing twelve month free cash flow of a loss of $300.81 million. Analyst estimates and extrapolations then project free cash flow moving to $1,198 million in 2030, with a path laid out for each year in between in dollar terms. Simply Wall St extrapolates beyond the explicit analyst window to fill out the 10 year view.

Pulling those projected cash flows together, the DCF model arrives at an estimated intrinsic value of $72.94 per share, compared with a current share price of $105.05. On this basis, the stock screens as about 44.0% above the DCF estimate.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Rocket Lab may be overvalued by 44.0%. Discover 48 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Rocket Lab Price vs Book

For companies that are still building toward consistent profitability, valuation based on the balance sheet can be more useful than earnings-based metrics. The price-to-book (P/B) ratio compares the stock price to the accounting value of net assets, so it focuses on what investors are paying relative to the capital already in the business rather than current profits.

Growth expectations and risk still matter, because investors usually accept a higher or lower P/B depending on how quickly a company is expected to grow and how uncertain that path might be. For Rocket Lab, the current P/B ratio is 26.86x, compared with an Aerospace & Defense industry average of 3.63x and a peer group average of 19.03x.

Simply Wall St also calculates a proprietary Fair Ratio, which is the P/B multiple it would expect for Rocket Lab after accounting for factors such as earnings growth, industry, profit margins, market capitalization and company-specific risks. This Fair Ratio can be more useful than a simple industry or peer comparison because it adjusts for the company’s own profile rather than assuming all stocks in the sector deserve similar valuations. In this case, the actual 26.86x P/B is assessed as higher than the Fair Ratio.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Rocket Lab Narrative

Earlier the article mentioned that there is an even better way to understand valuation. Meet Narratives, which let you attach a clear story about Rocket Lab to concrete assumptions for future revenue, earnings and margins. You can connect that story to a financial forecast and a Fair Value, then compare it with the current price in a simple view on Simply Wall St’s Community page. Narratives update automatically as new news or earnings arrive. Different investors can see, for example, one Rocket Lab Narrative with a Fair Value of about US$7.31 per share alongside another closer to US$149.03, reflecting very different views on Neutron, defense contracts and long term profitability.

For Rocket Lab however, we’ll make it really easy for you with previews of two leading Rocket Lab Narratives:

Start by asking which version of the future feels closer to how you see the business, the sector, and your own risk tolerance. Then compare that story with the current price and the DCF and P/B results above.

Fair Value: US$149.03

Implied upside vs current price: about 29.5% below this narrative fair value.

Revenue growth assumption: 38.81% a year.

• Sees Neutron and vertical integration as the core of a long runway in national security and constellation contracts, with an emphasis on high margin, end to end offerings.
• Builds in faster improvement in revenue and earnings than consensus, including a shift from current losses to positive earnings with higher profit margins over the next few years.
• Accepts higher execution, regulatory and funding risks in exchange for the potential that large government and defense programs support a higher long term valuation multiple.

Fair Value: US$97.83

Implied downside vs current price: about 7.4% above this narrative fair value.

Revenue growth assumption: 55.0% a year.

• Focuses on Rocket Lab as a key part of the wider space economy, but frames success as depending heavily on Neutron reaching low cost, reliable operations while keeping working capital under control.
• Highlights that competition, contract timing and the difficulty of space flight could limit how quickly revenue targets and margin improvements are achieved.
• Views fair value as materially below the current share price even with strong long term growth assumptions, so any setback on Neutron, contracts or profitability could weigh on returns.
