The Quarter That Has to Bridge the Story

Rocket Lab is now valued at about $48.4 billion, and trades at a multiple that assumes Neutron and defense scale up on schedule.

If management delivers a tight Neutron update, holds margins inside guidance, and converts backlog into recognized revenue, the next leg of the narrative writes itself. Guidance will be really important tonight for the stock.

Investors are watching Rocket Lab (NASDAQ: RKLB | RKLB Price Prediction) ahead of first-quarter 2026 results due May 7. After a record fourth quarter and a stumble by Neutron, this earnings report will test whether momentum still outweighs execution risk.

Record Backlog Meets a Neutron Setback

Rocket Lab closed 2025 strong. Q4 revenue hit $179.65 million, up 35.7% year over year, with non-GAAP gross margin of 44.3% and an EPS loss of -$0.09, beating the -$0.098 estimate. Full-year revenue reached $601.8 million (+37.96%) on 21 launches with 100% success.

The bigger story is the pipeline. Backlog ended at $1.85 billion, up 73% year over year, anchored by the $816 million Space Development Agency Tranche 3 award. Offsetting that, a stage-1 tank test failure pushed Neutron’s first launch to Q4 2026. Shares have absorbed the news, climbing 16.29% over the past month and 250.36% over the past year.

Q1 2026 Company Guidance

Neutron, Margins, and Defense Wins

I’ll be watching three things. First, I’ll be looking for an updated timeline for Neutron, along with a capex framework. Cash sits at $828.66 million, but FY2025 free cash flow was -$321.8 million, and capex was $156.3 million. The burn pace matters.

Second, margins. Q4’s 44.3% non-GAAP gross margin set a high bar, and Q1 guidance calls for a step down to 39%–41%. Investors will look at the mix between Space Systems and Launch, as well as how the $325 million Geost acquisition fits into the new Payloads unit.

Third, defense conversion. The SDA Tranche 3 kickoff and SHIELD selection by the Missile Defense Agency positioned Rocket Lab as a prime contractor. Backlog growth from 30+ new launch contracts signed in 2025 should keep flowing.

Sentiment has cooled. Reddit chatter shifted from very bullish in mid-April (sentiment score of 88) to neutral (45–54) as concerns about the SpaceX IPO competition dominated pre-earnings discussion. Analyst consensus target sits at $87.56 with 12 buys and 5 holds.
