• If you are wondering whether Rocket Lab's current share price still makes sense after such a strong run, you are not alone. This article is going to focus squarely on what you are paying versus what you are getting.
• The stock closed at US$68.93, with returns of a 1.7% decline over 7 days, a 4.7% decline over 30 days, a 9.3% decline year to date and 286.6% over 1 year. The 3 year return is very large and the 5 year return is also very large, which naturally raises questions about how much future upside or downside is already priced in.
• Recent coverage has focused on Rocket Lab's position as a listed space company and its growing role in launch and space systems contracts, which helps explain why sentiment has been so sensitive to news flow. Investors have been weighing these developments against the share price moves, trying to judge whether expectations have run ahead of fundamentals or still lag behind them.
• Even so, Rocket Lab currently scores just 1 out of 6 on our valuation checks. We will look at what different methods such as multiples and cash flow based models suggest about fair value, and then finish with an approach that can give you an even clearer picture of what the market might be missing.

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 estimates of a company’s future cash flows, then discounts them back into today’s dollars to arrive at an implied value per share.

For Rocket Lab, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is a loss of $296 million, so the story here is built around what future cash flows could look like rather than current profitability. Analysts and internal estimates project free cash flow moving to $84.9 million by the 2027 financial year, with a series of further annual projections out to 2035, all expressed in $ and mostly in the tens or low hundreds of millions each year.

When all of those projected cash flows are discounted back, the model arrives at an estimated intrinsic value of about $7.90 per share. Compared with the recent share price of $68.93, this implies the stock is far above this estimate of fair value, with an intrinsic discount of about 772.8%.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Rocket Lab may be overvalued by 772.8%. 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 where earnings are not yet a reliable guide, price based on book value can be a useful cross check because it anchors the share price to the net assets on the balance sheet rather than current profits.

In general, investors tend to pay a higher or lower P/B depending on what they expect for future growth and how risky those future cash flows appear. Higher growth and lower perceived risk can justify a richer multiple, while lower growth or higher uncertainty usually points to a more modest level.

Rocket Lab currently trades on a P/B of 22.72x, compared with an Aerospace & Defense industry average of 4.24x and a peer group average of 29.04x. Simply Wall St’s Fair Ratio is designed to refine this comparison by estimating what a more tailored P/B might look like after factoring in elements such as earnings growth, industry, profit margins, market cap and company specific risks, rather than relying only on broad peer or sector averages.

Because the Fair Ratio figure is not available here, it is not possible to reach a clear conclusion on whether Rocket Lab’s 22.72x P/B points to the shares being overvalued, undervalued or roughly in line with expectations.

Result: ABOUT RIGHT

Upgrade Your Decision Making: Choose your Rocket Lab Narrative

Earlier we mentioned that there is an even better way to understand valuation. Narratives let you attach a clear story about Rocket Lab to the numbers you see by linking your view of its business, your forecast for revenue, earnings and margins, and your own fair value estimate. You can then compare that to the current price to help you decide whether the stock looks attractive or stretched.

On Simply Wall St’s Community page, used by millions of investors, Narratives are an easy tool where you can set out your assumptions and see an instant fair value that updates automatically when new information such as news or earnings comes in. Your thinking stays current without needing to rebuild a model from scratch.

For Rocket Lab, one investor might look at the company’s cash position, Neutron development and backlog and land on a fair value around US$7.31 per share. Another might focus on the potential for Neutron, vertical integration and long term space demand and arrive at a fair value closer to US$120. Both Narratives sit side by side so you can judge which story, and which set of assumptions, feels closer to your own view.

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

Together they show how different assumptions on revenue, margins and fair value can lead to very different conclusions, even when both are built on the same core facts about the business.

Fair value: US$97.83

Implied undervaluation vs last close: about 30% below this fair value estimate

Revenue growth used in the narrative: 55%

• Sees Rocket Lab building a vertically integrated position across the US$800b space backbone, with both launch and space systems feeding into long term demand from satellite and services customers.
• Assumes Neutron scales to around 40 launches a year and supports a much larger, higher margin space systems segment, with the company eventually reaching US$6b revenue and strong net margins.
• Views SpaceX as the main competitor but not a direct roadblock, arguing that Rocket Lab can follow a lower cost, uncrewed, services focused path while benefiting from broader growth in the space economy.

Fair value: US$16.25

Implied overvaluation vs last close: more than 3x this fair value estimate

Revenue growth used in the narrative: 30%

• Accepts the long term potential of a vertically integrated space business, but argues that a lot of this is already reflected in the share price and that the current valuation assumes very smooth execution.
• Highlights Neutron as the key swing factor, with schedule slips, possible launch issues and the need for additional capital all flagged as risks that could affect timing of profitability and cash flow.
• Points out that Space Systems provides useful higher margin revenue, but that competition from SpaceX and the stock being seen as priced for perfection could lead to significant share price volatility.

If you want to see how other investors are joining the debate, there are more Narratives beyond these two, with a mix of bullish and cautious views that you can compare against your own assumptions.
