Gooch & Housego shares climb as defence order book drives growth

Gooch & Housego's order book has increased to £168.3m since 1 October (from £142.3m at year-end), fuelling a 7.41% share rise to 812p as aerospace and defence demand in the US and Europe strengthens. The AIM-listed photonics group reported firm demand across precision optics, optical systems and advanced imaging, capacity expansions at recent acquisitions (Global Photonics, Phoenix Optical), resolved supply-chain issues for Pockels cell orders with production to ramp in H2 FY2026, and net debt excluding leases reduced to £28.0m (31 Jan 2026) from £29.9m (Sept 2025). The board left full-year expectations unchanged, citing the larger order book, operational improvements and a growing pipeline of potential multi-year contracts.

Analysis

Market structure: Gooch & Housego (AIM:GHH) is a direct beneficiary of rising US/EU defence procurement and a nascent H2 2026 semiconductor recovery; its orderbook rising from £142.3m to £168.3m (+18%) since 1 Oct implies multi-quarter revenue visibility and greater pricing leverage in precision optics. Suppliers of defence-grade photonics, aerospace OEMs and recently-acquired Global Photonics/Phoenix Optical gain scale; commoditised optical component makers and low-margin subcontractors face pricing compression.

Risk assessment: Tail risks include contract cancellations, integration failure of acquisitions, or renewed supply-chain stoppages for Pockels cells — any of which could flip a back-end weighted FY2026 into a revenue miss. Near-term (days–weeks) risk is sentiment-driven around orderbook/earnings commentary; medium-term (3–9 months) is execution on capacity expansion and deferred-consideration cash outflows; long-term (>12 months) is sustainability of defence-funded demand.

Trade implications: Prefer a company-specific long with market-hedge rather than broad sector exposure — GHH’s orderbook and modest net debt (£28.0m ex-leases) support a 6–12 month bullish thesis, but hedge execution risk via puts or index futures. Rotate modest overweight into Aerospace & Defence names (BAE Systems LSE:BA, RTX NYSE:RTX) and underweight cyclical semiconductor equipment (ASML, LRCX) until H1 2026 bookings confirm the recovery.

Contrarian angle: Consensus may underweight integration and capex strain — capacity increases can depress margins short-term and deferred consideration payments can spike cash outflows if milestone timing slips. The 7% intraday move is reasonable but not extreme; mispricings will appear on any orderbook slowdown or missed Pockels-cell ramp, creating tactical short/option plays.

Key Decisions for Investors

• Establish a 2–3% long position in Gooch & Housego (AIM:GHH) within next 2–6 weeks; target 20–30% upside (≈980–1,050p) over 6–12 months and set a tactical stop at -12–15% (≈700–710p).
• If liquid, implement a capped-call spread to reduce cash outlay: buy 9–12 month GHH ATM call and sell a 1,100p call (size 0.5–1% portfolio risk); if options illiquid, buy the stock and hedge with a 6–9 month protective put at ~12–15% OTM.
• Hedge market/beta: short FTSE futures or buy FTSE put options sized to offset ~50% of market exposure of the GHH position for 3–6 months to isolate company-specific upside during possible market volatility.
• Rotate 1–2% into Defence primes over next 3 months: buy BAE Systems (LSE:BA) and RTX (NYSE:RTX) to capture sustained defence spend, and reduce 1–2% exposure to semiconductor-equipment names (ASML, LRCX) until H1 2026 equipment-booking indicators confirm recovery.
• Trigger-based sizing: if GHH orderbook expands another ≥10% or net debt falls below £20m within 90 days, scale position up to 4–5%; conversely reduce/remove exposure if Pockels-cell volumes fail to ramp by end-FY2026 or a major contract is delayed.
