Rocket Lab (RKLB) just checked two big boxes for investors, qualifying its world first reusable Neutron fairing and successfully flying JAXA’s dedicated RAISE And Shine mission, together strengthening its case for higher margin, repeat business.

See our latest analysis for Rocket Lab.

The latest pullback, with a roughly 9.9% one day share price return decline after the JAXA success, looks more like profit taking than a change in thesis. This is especially the case given Rocket Lab’s triple digit year to date share price return and huge multi year total shareholder return, which suggests momentum is still broadly building rather than fading.

If this kind of space momentum has you rethinking your portfolio, it could be a good time to explore aerospace and defense stocks for other potential beneficiaries of the sector’s tailwinds.

With shares up more than 120% this year and trading only modestly below analyst targets despite ongoing losses, the key question now is simple: is Rocket Lab still an underappreciated growth story, or has the market already priced in liftoff?

Most Popular Narrative Narrative: 43.4% Undervalued

KiwiInvest’s narrative points to a fair value far above Rocket Lab’s last close, framing today’s price as a steep discount on long term potential.

These estimates produce a current fair value of ~$98 per share. The main determinant of daily stock prices over the next 10 years will be the PE ratio the market ascribes to Rocket Labs. This will fluctuate massively over time as an amplified measure of current investor confidence in the spaceflight business, the space economy, the global economy and global markets in general. Throughout Rocket Lab will continue to innovate and grow. Periods of lower PEs will offer good buying opportunities. Only extremely high PEs represent true overvalued status, given the long term prospects of this company.

Want to see how ambitious revenue expansion, rich margins and a premium future earnings multiple combine into that price target? The underlying forecasts might surprise you.

Result: Fair Value of $98 (UNDERVALUED)

However, persistent losses, Neutron setbacks, or fiercer price competition from SpaceX could quickly erode the bullish long term valuation narrative around Rocket Lab.

Another Lens on Valuation

While KiwiInvest sees Rocket Lab as deeply undervalued, our SWS DCF model paints a cooler picture, with fair value at $37.84 versus a $55.41 share price, implying the stock is overvalued on this view. Is the market already paying up for future Neutron wins?
