AEHR TEST SYSTEMS Business Summary

Aehr Test Systems (AEHR) generates revenue through the sale of high-performance semiconductor test and burn-in systems, consumable contactors, and lifecycle services. The company’s primary business segments include Wafer-Level Burn-In (WLBI) and Packaged-Part Burn-In (PPBI), anchored by its flagship FOX-XP and Sonoma platforms. As of February 2026, Aehr has strategically pivoted from a heavy concentration in silicon carbide (SiC) for electric vehicles toward the high-growth AI and hyperscale data center markets, recently securing major production orders for next-generation AI ASIC testing. In the competitive landscape, Aehr contends with industry giants such as Teradyne, Advantest, Cohu, and FormFactor; however, it maintains a distinct market position as a niche leader in massively parallel wafer-level testing, offering superior cost-of-test efficiencies for complex, high-power semiconductors. Founded in 1977 by Rhea Posedel, who currently serves as the Independent Chairman of the Board, Aehr is led by President and CEO Gayn Erickson, a veteran with over 35 years of experience from Agilent Technologies and Hewlett-Packard. The executive team includes CFO Chris Siu, who oversees financial strategy during the company's AI-driven expansion, and CTO Donald P. Richmond II, a specialist in wafer-level reliability with a background at ChipScale and TEAM Holdings. Operational execution is managed by COO Adil Engineer, formerly of KLA-Tencor and Tecan. The company’s board of directors features notable industry figures such as Dr. Laura Oliphant, a former Investment Director at Intel Capital, and Mario M. Rosati, a prominent Silicon Valley legal and corporate strategist, reflecting a leadership pedigree deeply rooted in semiconductor capital equipment and venture-backed growth.
