Segment Reporting [Abstract]

SEGMENT INFORMATION

SEGMENT INFORMATION

We have three operating segments which are also our reportable segments and reporting units: Electronic Test (which includes our semiconductor test equipment, flying probe and in-circuit testers and the operations of Alfamation™ which we acquired on March 12, 2024 - see “Note (3) Acquisition”), Environmental Technologies (which includes our thermal test, process and storage products) and Process Technologies (which includes our induction heating and video imaging products). We operate our business worldwide and sell our products both domestically and internationally. All of our segments sell to semiconductor manufacturers, third-party test and assembly houses and ATE manufacturers and to a variety of markets outside of the semi market, including the auto/EV, defense/aerospace, industrial, life sciences, safety/security and other markets.

Our management team, including our CEO who is also our Chief Operating Decision Maker as defined under U.S. GAAP, evaluates the performance of our operating segments primarily on income from divisional operations which represents earnings before income tax expense and excludes interest expense, other income (expense), corporate expenses, restructuring costs and acquired intangible amortization.
