Leonardo's core advantage is real and threefold: installed-base lock-in, program incumbency, and multi-domain integration breadth — strongest in electronics and mission systems, weaker in lower-value manufacturing and civil-exposed aerostructures. Once sovereign customers operate Leonardo's radars, electronic-warfare systems, and helicopters, they need years of spares, software upgrades, training, and support — switching costs rooted in certification and mission assurance rather than brand preference, reflected in support and service revenue running around 26% of the total in 2024. Program incumbency in Eurofighter, the F-35 supply chain, and GCAP rests on decades of qualification, export approvals, and government relationships a competitor cannot simply out-bid. A third layer — electronics as the connective tissue integrating sensors, communications, and command systems across air, land, sea, and space — showed up concretely in Q1 2026, when Electronics Europe grew orders 19.7% and revenue 14.7%. The report is explicit about what is not a moat, though: GCAP's cash realization sits too far out to protect shareholders today, and state backing helps access but constrains capital flexibility rather than functioning as an economic moat.
Over three to five years, the moat is modestly widening at the core — the rearmament cycle deepens installed-base lock-in, and the land-systems push extends the integration franchise into a new domain — but not group-wide. "Other activities" ran a -48.7% EBITA margin in 2025 and remains an unresolved drag, aerostructures stays civil-exposed and weak, and land-platform integration carries real execution risk. Meanwhile the valuation gap to Thales and BAE Systems (trailing P/E near 30.9x versus roughly 29.2x for both peers) has already closed, even though the report argues the underlying quality and moat gap has not — meaning the market may be pricing convergence ahead of it actually happening.
