Analysis
Three defense-and-space companies priced within days of each other this week, and the spread between them is the clearest numbers-driven read yet on how differently private and public markets are treating the sector right now, per Value Add Pulse's own IPO tracking.
Castelion, the hypersonic-missile startup founded by former SpaceX executives, is still building out its New Mexico manufacturing capacity, but that hasn't slowed its private-market pricing:
- Round -- $1B Series C, co-led by Andreessen Horowitz, Carlyle and JPMorgan
- Valuation -- $13B
- Secured US military contracts -- $500M+
- Implied multiple -- roughly 26x contracted revenue
That's aggressive private-market pricing by any measure.
Days earlier, Lyntris, a defense-tech roll-up, priced its actual public IPO at $17.50 a share -- below its $19-to-$22 target range -- raising roughly $297.5 million ahead of its NYSE debut. A below-range public print, landing in the same week as Castelion's rich private valuation, is a real-time gut check: public investors did not extend Castelion-level enthusiasm to a comparable defense name once it actually had to clear a bookbuilt IPO process rather than a private round negotiated directly with a small group of investors.
Gravitics adds a third, different data point: a $125 million Nasdaq listing via reverse merger, priced against zero disclosed revenue and a $24.5 million six-month net loss -- reaching public markets through a faster, less price-discovery-intensive structure than either Castelion's private round or Lyntris's traditional IPO used.
What the spread says
The pattern across all three: capital is still flowing hardest toward private companies with the most direct, largest-dollar Pentagon relationships, while public markets are pricing more cautiously on names without an equivalent contract base to point to -- Lyntris's below-range print and Gravitics's zero-revenue reverse-merger path both reflect a public market less willing to extend Castelion's 26x private multiple to companies it can actually vote on with real-time demand. Private investors, negotiating directly and taking a longer view, are still willing to underwrite growth stories public bookbuilding hasn't yet validated at the same multiple.
