Summary
AAR Corp has agreed to acquire a 65% controlling interest in aircraft maintenance provider MRO Holdings at a $4 billion implied enterprise value, marking a significant consolidation in the heavy maintenance sector. The Chicago-area company will pay approximately $1.8 billion for its equity stake while assuming roughly $1.3 billion of MRO's existing debt obligations. The transaction preserves Bain Capital's investment position alongside other existing owners, who will maintain minority stakes in the combined platform.

MRO Holdings, currently backed by Bain Capital, operates approximately 10,000 employees providing aircraft maintenance and modifications across five facilities throughout the Americas. AAR, which supplies parts, repair services, and software solutions to commercial aviation and government customers, positions the combined entity as a comprehensive heavy maintenance provider. The acquisition aligns with AAR's strategy to expand its maintenance capabilities and customer service footprint within the aerospace and defense supply chain.

In separate deal activity, private equity firm GTCR has acquired Tactacam, a cellular-connected camera platform, from Bertram Capital and the company's founders for more than $1 billion. Tactacam operates a subscription-based model serving over one million users for trail and security camera applications. CEO and co-founder Jeff Peel and co-founder Ben Thorud will remain active in leadership roles with significant retained ownership, maintaining entrepreneurial continuity following the transition. Bertram Capital, which invested in Tactacam in 2023, exits the investment through the transaction.

Separately, Samsung Electronics has committed $1 billion in long-duration capital to Helix Digital Infrastructure, the AI infrastructure investment platform launched by KKR in June. The investment brings total committed capital to Helix above $10 billion, with anchor investors including KKR, Kuwait Investment Authority, Nvidia, and Vistra. Samsung's participation signals institutional commitment to hyperscale data center, power, connectivity, and related infrastructure development, with potential future collaboration across Samsung's technology, construction, energy storage, and cooling capabilities.
