Summary
Mario Mancuso, CEO and co-founder of DealSage and a former leader of the CFIUS and national security practice at Kirkland & Ellis, says aerospace and defense (A&D) transactions face more caution ahead, particularly those involving legacy players, if Congress is led by the Democratic Party. In remarks reported by Steve Gelsi, Mancuso argued that the added scrutiny is likely to be targeted rather than systemic.

Despite the expected caution in A&D, Mancuso expects overall M&A volume to stay robust. In his view, buyers will continue to seek out faster-growing businesses, which should sustain deal activity across sectors. The article is limited to these views and does not provide transaction values, deal counts, or specific regulatory actions.

For institutional investors and deal professionals, the key distinction is between legacy A&D assets, which may face heavier review, and higher-growth targets, which are expected to remain attractive to acquirers.
