HEICO (NYSE: HEI) is trading higher today as investors re-rate the company on fresh M&A momentum in defense-tilted aerospace niches. In the past week, HEICO disclosed two acquisitions: its Flight Support Group bought 80% of Sherwood Avionics and Accessories, a defense and select commercial aviation repair operation focused on APU and component overhaul, and its Electronic Technologies Group bought 90% of Southwest Antennas, a maker of rugged RF and microwave antennas used in defense, law enforcement, and other mission-critical applications.

The pair of transactions reinforces HEICO’s playbook of acquiring specialized, high-reliability suppliers and aftermarket service providers—segments that can be less cyclical than OEM build rates and can generate repeat demand tied to installed fleets. Investors appear to be responding to the expanded exposure to defense-related communications hardware and repair/overhaul services, which typically carry sticky customer relationships and long program lives.

The next major catalyst is earnings. Market calendars currently point to HEICO’s next earnings release on June 2, 2026, which could clarify near-term integration priorities, acquisition financing, and whether management expects these deals to be accretive on an operating basis in the current fiscal year.
