Better Space Stock: Rocket Lab vs. Firefly Aerospace

Rocket Lab generated $403M in space equipment revenue and $199M in launch revenue in 2025 and recorded a $200M net loss, while Firefly posted $160M revenue and nearly $300M net loss after raising $868M in its public offering last year. Rocket Lab trades at a P/S of ~60 versus Firefly's ~32 and is favored here due to a stronger commercial launch track record and higher cadence of Electron launches, despite both stocks appearing richly valued.

Analysis

Public appetite for “space” is driving valuations that price long-dated execution rather than near-term cashflow, so the key discriminant is path-to-cashflow visibility and optionality on government/defense awards. Second-order winners are not just launchers: avionics and composite suppliers, launch-site services, and satellite-integration specialists will see margin expansion if launch cadence scales; conversely, insurance/reinsurance and legacy prime integrators face renewed pricing pressure and procurement re-optimization. Execution risk is asymmetric — a single failed mission or missed development milestone can wipe out multiple years of implied upside for high-multiple names, while defense contract awards can create step-function revenue inflection points that equity markets rerate within days. Capital markets dynamics matter: frequent equity raises at steep discounts are the most likely path to dilution for weaker balance sheets, while clearer backlog conversion and margin improvement can compress implied volatility and lift equity multiples quickly.

Key Decisions for Investors

• Initiate a tactical long in RKLB sized 1.5% NAV with a 12–36 month horizon; hedge downside by buying 9–12 month ATM puts equal to 50% of notional to cap a 30–40% equity drawdown. R/R: target 2.5x upside if execution continues and market narrows multiples; pain-case is capital raises or a launch failure within 6 months.
• Establish a dollar-neutral pair: long RKLB / short FLY (1:1) sized 1% NAV each, horizon 9–18 months. Rationale: capture relative execution and commercialization divergence while minimizing sector beta; trim if RKLB/FLY spread compresses by 30% or if either announces a material defense contract.
• Buy an RKLB 18-month call-debit spread (buy LEAP call / sell higher strike LEAP) to express convex upside while limiting premium. Size to 0.75% NAV; payoff targets >3x premium if cadence and service revenue accelerate; max loss = premium paid if sector derates.
• Short FLY via put-spread or small outright position (0.5–1% NAV) rather than naked short to limit blow-ups; cap risk by buying a long-dated call as protection. Catalysts to watch: cash raises, NASA/DoD award announcements, and any M&A rescue — exit or hedge immediately on those events.
