Satellite Manufacturing

COMMERCIAL · 59 operators · HHI LOW

Design, manufacture, and integration of satellite buses and complete spacecraft, together with the merchant component supply chain that feeds them - solar cells and arrays, batteries and power systems, reaction wheels, star trackers, optical communications terminals, electric propulsion, and flight computers. Revenue comes from fixed-price productized bus sales, prime contracts for proliferated defense constellations, and recurring merchant component orders. Demand is anchored by the Space Development Agency's tranche procurement cadence - recompeted transport and tracking layers that reward standardized, high-rate production - plus commercial broadband and direct-to-device constellation buildouts. The sector's defining tension is vertical integration: constellation operators in-house production while defense primes acquire merchant suppliers, shrinking the open merchant market even as newly funded productized entrants scale up.

UNIT ECONOMICS — FORMULA + NUMBER + SOURCE

• $/satellite by class (formula: contract value / units, from SDA award releases and company PRs): cubesat/microsat bus ~ EUR 0.44M (NanoAvionics-SpinLaunch: EUR 122.5M / 280 buses = EUR 437K/bus); SDA transport class ~ $9-10M/sat (York T1: $382M / 42 = $9.1M; T2 Alpha: $615M / 62 = $9.9M); SDA with full in-house subsystems $28.6M/sat (Rocket Lab T2TL-Beta: $515M / 18); missile-tracking class ~ $41M/sat (Sierra T2 Tracking: $740M / 18); MicroGEO $50-100M class (Astranis, >$1B backlog reported by the company); heritage GEO $150-300M (Lanteris 1300 class).
• Implied $/kg ladder (derived from the $/sat anchors above over typical bus masses): ~$2-4K/kg (Starlink, internal, estimate) to ~$30-45K/kg (SDA transport, ~250 kg class) to ~$50-80K/kg (GEO/missile-tracking).
• Margins, reported actuals: York FY25 gross margin 19.5% with adjusted EBITDA at -2.1% of revenue at $386M scale (8-K); Rocket Lab FY25 GAAP gross margin 34.4% / non-GAAP 39.7% blended across launch + components at $602M revenue with $1.85B backlog (FY25 earnings release); MDA FY25 adjusted EBITDA margin 19.8% at CA$1.63B revenue with CA$4.0B backlog (earnings release).
• Underwriting rule of thumb for a bus integrator (derived from the reported actuals above): gross margin 15-25%; EBITDA breakeven only above ~$400-500M revenue; working capital negative during ramps because milestone billing lags bill-of-materials buys; capacity capex ~CA$225-275M for a 400-satellite/yr line (MDA 2026 guidance).

KEY RISKS — INCLUDING THE INSURANCE ANGLE

• Monopsony / sole-source drift: SpaceX MILNET capturing transport demand kills the recompete cycle merchant builders priced for — York's post-IPO fade ($38 open to ~$26.5 by Feb 2026) is the market repricing exactly this risk.
• Anchor-customer credit: OneWeb's Chapter 11 (2020) and Rivada's unfunded $2.4B order at Terran Orbital are the canonical losses — backlog is only as good as the counterparty's financing.
• Fixed-price defense work at immature rate lines produces negative-margin backlog (Terran Orbital's pre-acquisition history).
• Component bottlenecks: Orbion states electric-propulsion demand exceeds industry-wide capacity; Blue Canyon is quadrupling reaction-wheel output — schedule liquidated damages flow up to bus primes.
• Insurance angle: ground/transit and pre-launch insurance demand grows with factory throughput — AIT damage and TVAC/vibration test failures are insurable events. The on-orbit market remains hard after the 2023-24 GEO losses, pushing constellation operators to self-insure, which means manufacturing defects increasingly hit operators' P&L directly — raising the value of quality/test infrastructure and creating an opening for test-services entrants.
• Valuation froth: Apex $2.3B, K2 $3B, Sierra Space $8B, Astranis $2.8B (press-reported) against zero or minimal disclosed revenue, vs York at roughly 2x EV/backlog at IPO — the private-public multiple gap implies markdown risk in any 2026-27 risk-off.

THESIS: Gemma (cached)

HHI estimated from ARI-weighted market-share proxy (ARI × data-coverage, normalized). 0 = perfectly competitive, 1 = single-operator monopoly. Banding: <0.15 Low, 0.15-0.25 Moderate, 0.25-0.50 High, >0.50 Concentrated.

• 01 The next quarterly earnings print from the top public Satellite Manufacturing operators — backlog, guidance, and any cash-runway inflection will mark comps for the entire peer group.
• 02 Government contract renewals and new-start awards inside Satellite Manufacturing — each award validates or resets the anchor-demand assumption that underwrites the sector's valuations.
• 03 Any primary funding round inside Satellite Manufacturing, particularly down-rounds or pro-rata waivers — these reset cap tables and tell us where late-stage capital is willing to clear.
