Technological disruption from sustainable aviation fuels (SAF) and hydrogen propulsion: LEAP engines certified for 50% SAF blends, but 100% SAF or hydrogen would require new engine architectures by 2035-2040, potentially stranding €15B+ R&D investment and installed base economics
Regulatory pressure on aviation emissions: EU ETS carbon costs, CORSIA offsetting requirements, and potential jet fuel taxes could suppress air travel demand growth from 4-5% historical to 2-3% annually, reducing aftermarket growth trajectory
Geopolitical fragmentation of aerospace supply chains: 40% of CFM engine content sourced from US (GE partnership), 30% from Europe, creating exposure to export controls, tariffs, and US-China decoupling
Pratt & Whitney GTF engine reliability improvements: current shop visit issues provide competitive advantage for LEAP, but resolution could shift A320neo market share from 60/40 LEAP/GTF to 50/50 by 2028-2030
Chinese COMAC C919 and Russian MC-21 substitution: domestic engines (CJ-1000A, PD-14) could displace CFM in 15-20% of narrowbody market by 2035 if geopolitical tensions persist
OEM vertical integration: Boeing and Airbus increasing in-house capabilities in avionics, electrical systems, and nacelles, threatening 15-20% of Safran's equipment revenue
Pension obligations: €8B defined benefit liabilities (France, UK) with 4.5% discount rate assumptions; 50bps rate decline would increase obligations by €800M-1B
Working capital volatility: OEM production rate changes create €1-2B quarterly swings in advance payments and inventory; 737 MAX or A320 production cuts would consume €500M-1B cash
Currency exposure: 65% revenue in USD/GBP, 55% costs in EUR; 10% USD weakness reduces operating income by €300-400M annually despite hedging program covering 80% of 12-month exposure
