Live Earnings: Complete Rocket Lab (RKLB) Coverage

Rocket Lab USA (NASDAQ: RKLB | RKLB Price Prediction) reports Q4 FY2025 earnings today, and the stakes are high. With shares up 230% over the past year but down nearly 12% over the past month, investors want answers on Neutron, margins, and the path forward.

A Record Quarter Sets a High Bar

Last quarter, Rocket Lab delivered record revenue of $155.08 million, up 48% year over year, beating estimates by a hair. More importantly, GAAP gross margin hit 37%, also a record, showing the business is scaling with discipline. EPS came in at -$0.03, beating the -$0.11 estimate by a wide margin.

For Q4, management guided to revenue of $170 million to $180 million with GAAP gross margins of 37% to 39%. That midpoint implies roughly 34% year-over-year growth, a step down from Q3’s torrid pace but still exceptional for a company this size. Analysts are largely aligned, with consensus revenue estimates sitting around $176 to $178 million.

Consensus Estimates

5 Things to Watch

1. Neutron Timeline After the Tank Rupture

This is the biggest wildcard heading into the call. Last quarter, Peter Beck told investors that Neutron was on track for a pad arrival in Q1 2026. Since then, reports surfaced of a Stage 1 tank rupture during testing. That kind of incident is not automatically catastrophic, Beck himself said the point of ground testing is to find problems before flight, but it does raise questions about whether the Q1 timeline holds. I’ll be listening closely for how management characterizes the incident and whether they update the launch window.

2. Gross Margin Expansion

Rocket Lab guided for non-GAAP gross margins of 43% to 45% in Q4, a meaningful step up from Q3’s 41.9%. The drivers are higher Electron launch cadence, better average selling prices, and overhead absorption. CFO Adam Spice has laid out a long-term target of 45% to 50% non-GAAP gross margins for Electron at scale. Watch whether Q4 results keep that trajectory intact.

3. Electron Momentum and the 50th Mission

Electron just hit its 50th mission milestone, a meaningful proof point for a rocket that launched for the first time in 2017. The company secured 17 new launch contracts in Q3 alone, a record, and total backlog stood at 49 launches on contract. Investors will be watching whether Q4 contract signings sustain that pace and whether management raises the annual cadence target beyond 30 flights.

4. Defense Exposure and SDA Tranche 3

Rocket Lab’s positioning in government programs is becoming a core part of the bull thesis. The Geost acquisition, closed last quarter for $325 million, strengthens the company’s standing as a prime contractor for programs like Golden Dome and Space Development Agency constellations. Beck called it “well-timed, strategic M&A in growth areas aligned with next-generation defense programs.” SDA Tranche 3 would be the largest contract in company history. Any update on timing matters.

5. The Path to Profitability

Rocket Lab is burning cash. Adjusted EBITDA loss guidance for Q4 is -$23 million to -$29 million, and free cash flow will remain negative as Neutron development spending stays elevated. The company has over $1 billion in liquidity, so there’s no near-term crisis, but investors are watching for any narrowing of the loss trajectory. Prediction markets are pricing an 84.5% probability of an earnings beat, which sets a high bar.

Rocket Lab is at an inflection point. The Electron business is operationally strong and gaining global momentum. The space systems segment is growing with real defense tailwinds. But Neutron is the variable that could either accelerate the stock’s re-rating or reset expectations sharply. With shares trading at $72.29 against an analyst target of $83.96, the market is pricing in execution. This quarter, management needs to show it can deliver on both the numbers and the narrative.
