Scope: company / Rocket Lab (RKLB)

## Summary

Rocket Lab's August 10 results reported $234 million of Q2 revenue and $2.36 billion of backlog. The next research question is conversion into launches and spacecraft deliveries.

## What changed

- Q2 revenue increased 62% year over year; backlog increased 137%.
- Management reported more than $437 million in launch contracts across Q2 and post-quarter signings; the figure includes options.
- The release targeted delivery of Neutron to the launch pad in Q4 2026. This is a target, not a completed launch.
- Mynaric and Motiv acquisitions were closed; the Iridium acquisition was announced, not described as closed.

## Why it matters

The release supports Rocket Lab's launch and space-systems role. Contract options and development targets need separate tracking from firm deliveries; backlog growth is not by itself proof of profitable execution.
