Rocket Lab Stock: Bull vs. Bear

Rocket Lab reported Q2 2026 revenue of $234M, up 62% YoY, and increased backlog 137% YoY to a record $2.36B, while guiding Q3 revenue of $250M-$265M. The stock remains expensive at ~51x trailing sales and posted a $49M net loss in Q2. The company also delayed Neutron, with the earliest launch now in Q4 2026 and a potential slip into 2027, but secured $266M and $397M defense/space contracts in July and August to support growth.

Analysis

RKLB is trading like a duration asset, not a normal aerospace contractor: the market is paying today for a future step-up in launch economics and margin that still depends on an unproven flagship vehicle. That makes the stock unusually sensitive to schedule drift; every quarter of delay pushes out the EBITDA inflection, increases capital intensity, and raises the odds of equity dilution if management keeps building ahead of cash flow.

The likely second-order winners are the lower-risk ways to own the same budget pool. If defense and government spending remain the cleanest demand driver, prime contractors like LMT, NOC, and RTX can absorb incremental space-related dollars without binary launch execution risk, while broader aerospace/defense proxies such as ITA or XAR can capture the rotation if investors de-risk out of pure plays. A clean first flight would reverse this quickly, but until then the market is paying full multiple for an option that has not yet cleared its key technical hurdle.

The contrarian miss is that backlog alone is not the thesis; contract quality and cash conversion are. Fixed-price space contracts can expand revenue while still compressing margins if development timelines slip, and the stock’s premium leaves little room for “good enough” execution. The key falsifier is a verified Neutron flight plus credible guidance that adjusted EBITDA turns positive on schedule; absent that, any additional delay or funding signal should drive multiple compression, not just volatility.

Key Decisions for Investors

• Do not chase RKLB strength ahead of the next launch window; use any rally into event dates to trim exposure unless there is a clearly documented, near-term flight path.
• For bearish expression, buy a 3-6 month RKLB put spread rather than shorting outright; the position is designed to monetize another delay or dilution cue while limiting squeeze risk.
• Pair trade: long LMT/NOC/RTX or ITA/XAR vs. short RKLB for investors who want space-defense exposure with lower execution risk over the next 1-3 months.
• Set an alert on any Neutron schedule change or financing commentary; if the first flight slips again or capital needs rise, treat that as a thesis break and add to the bearish position.
• If Neutron flies cleanly before year-end and management reiterates the post-launch EBITDA inflection, cover bearish trades quickly; that is the one catalyst that can justify the premium multiple.
