Rocket Lab (RKLB) has just expanded its national security work by joining the U.S. Space Force’s NITE-STAR test and training contract and winning new roles on Viasat’s Protected Tactical SATCOM-Global program.

Despite this contract momentum, Rocket Lab’s share price has been under pressure, with a 7 day share price return down 15.47% and a 90 day share price return down 55.46%, even as the 1 year total shareholder return is 39.02%. This suggests long term holders have still seen very strong gains.

Bulls point to Rocket Lab’s growing government backlog and improving cash burn, while bears focus on ongoing losses and recent equity dilution. Which side looks more convincing once you compare those facts with today’s share price?

Most Popular Narrative: 21.3% Undervalued

According to the most followed Rocket Lab narrative, a fair value of $85.04 sits well above the last close at $66.91, which frames the current pullback as a discount rather than a warning sign.

Rocket Lab is mid transformation from a small launch specialist into a vertically integrated space and defense prime, with Space Systems now ~67% of revenue and growing fastest.

A $1.85B backlog (+73% YoY) anchored by the $816M SDA Tranche 3 award provides multi-year revenue visibility that the current trailing P/S of ~72x does not yet fully reflect.

The fair value story leans heavily on accelerating revenue, rising margins and a bigger share of defense work. One piece of that financial puzzle carries most of the weight. The rest is about how long the current contract pipeline can support that trajectory.

Result: Fair Value of $85.04 (UNDERVALUED)

However, Rocket Lab’s fair value story hinges on smooth execution of Neutron and timely conversion of its government backlog, and setbacks on either front could quickly challenge this 21.3% undervalued narrative.
