Summary
Advent International, a leading global private equity firm, acquired a 7% stake in Avio, an Italian aerospace and defense manufacturer, for €109 million. The investment was structured as part of a capital increase executed by Avio, with parent company Leonardo conducting an accelerated bookbuilding placement to facilitate the transaction. Leonardo maintained operational and strategic control of the business while diversifying its shareholder base and accessing growth capital.
The transaction aligns with Advent's established investment thesis in the defense and national security sector. In March 2026, Advent announced a commitment to invest up to €1 billion in next-generation defense technology companies, with initial commitments to Shield AI and Saronic, a maritime autonomous systems developer. The Avio investment represents a complementary position in traditional aerospace and defense infrastructure, positioning Advent to capture exposure across both emerging defense technologies and mature, mission-critical industrial assets.
Avio operates as a vertically integrated aerospace and defense supplier, producing propulsion systems and advanced materials for commercial and defense applications. Its position within the broader Leonardo group—Italy's primary defense contractor—provides strategic visibility into European defense procurement cycles and NATO modernization spending. The capital increase signals confidence in Avio's growth trajectory amid sustained elevated defense budgets and multi-year procurement cycles across allied nations.
The transaction reflects broader institutional appetite for aerospace and defense assets in an environment characterized by sustained geopolitical tension, defense budget expansions, and strategic focus on industrial resilience and supply chain sovereignty among NATO members. Advent's entry as a minority shareholder provides operational flexibility while maintaining Leonardo's strategic oversight of the subsidiary.
