Aerospace & Defense Deal Count Doubles as the Iran War Pours Fuel on a Hot Sector

What's New

Defense dealmaking is booming. Aerospace & defense (A&D) private equity deal count more than doubled in Q1 2026 to an estimated 143 transactions — a 123% jump from the 64 confirmed deals in Q1 2025 — even as total deal value fell, according to PitchBook's Q1 2026 Aerospace & Defense Report. The driver is unmistakable: the Iran war is adding fuel to an already-hot sector.

Why It Matters

The split between soaring deal count and falling deal value reveals the PE playbook in defense: with primes off-limits, sponsors are buying smaller component and subcomponent makers and building platforms to scale. It's a land grab for the supply chain rather than the marquee contractors.

Big Picture Drivers

Geopolitical tailwind: Heightened conflict is lifting demand across the A&D vertical.
Smaller-deal strategy: Rising count and falling value show PE targeting bolt-ons over big-ticket deals.
Supply-chain access: Unable to own prime contractors, sponsors invest in component and subcomponent manufacturers.
European angle: The report flags improving European defense conditions as a positive for PE investors.

By The Numbers

143 deals: Estimated Q1 2026 A&D PE count (100 confirmed + 43 estimated).
+123% YoY: Versus 64 confirmed deals in Q1 2025; also up 22% over Q4 2025.
$11.3B: Q1 2026 deal value, down 26% YoY and 7.4% below Q4 2025's $12.2B.

Key Trends to Watch

Platform building: Expect continued roll-ups of smaller defense suppliers into scaled platforms.
"Operation Epic Fury": The report details PE implications rippling across the A&D vertical.
Issue spreads: Financing conditions remain supportive, though the Iran war adds near-term macro uncertainty.

The Wrap

Defense is one of the few corners of private markets where geopolitics is a direct accelerant. With deal count surging and sponsors methodically assembling supply-chain platforms, A&D looks set for a sustained PE run — even if individual checks stay small. The sector's momentum is structural, and the conflict has only sharpened it.
