SUBSEQUENT EVENT

In December 2019, the Company, through HEICO Electronic, acquired 80.1% of the stock of Quell Corporation ("Quell"). Quell designs and manufactures electromagnetic interference (EMI)/radio-frequency interference (RFI) and transient protection solutions for a wide variety of connectors that principally serve customers within the aerospace and defense markets. The remaining 19.9% continues to be owned by certain members of Quell's management team. The purchase price of this acquisition was paid using cash provided by operating activities and the total consideration for the acquisition is not material or significant to the Company’s consolidated financial statements.
