Aehr Test Systems Dossier
Qualitative Analysis
Business overview
Aehr Test Systems (NASDAQ: AEHR) is a leading global provider of advanced test and burn-in solutions for the semiconductor manufacturing industry. The company specializes in designing, manufacturing, and marketing wafer-level and package-level parallel test and burn-in systems. Its core product portfolio includes the FOX-P family of test and burn-in systems (FOX-XP, FOX-NP, and FOX-CP), the FOX WaferPak Aligner, FOX WaferPak Contactors, and FOX DiePak Carriers. These systems enable semiconductor manufacturers to perform full-wafer and singulated die/module testing, burn-in, and stabilization. Aehr's technology is critical for high-growth, mission-critical applications including silicon carbide (SiC) and gallium nitride (GaN) power semiconductors, silicon photonics optical transceivers, advanced artificial intelligence (AI) processors, and automotive/mobility integrated circuits. Following its acquisition of Incal Technology, Inc., Aehr has expanded its footprint into high-power package-level reliability and burn-in test solutions, notably with its Sonoma family of test solutions targeting AI accelerators, GPUs, and high-performance computing (HPC) processors.

Strategic Initiatives
Growth programs, investments, and their expected impact
Leveraging the newly acquired Incal Technology packaged-part reliability and burn-in test solutions (including the Sonoma, Tahoe, and Echo series) to address ultra-high-power requirements of AI accelerators, GPUs, and HPC processors.
Expected impact: Diversifies revenue away from historical concentration in silicon carbide for electric vehicles and establishes Aehr as a turnkey provider in the rapidly growing AI hardware market.
Deploying high-power FOX-XP wafer-level burn-in systems configured to test nine wafers in parallel to support the transition from copper interconnects to fiber optic communication links in hyperscale data centers.
Expected impact: Positions Aehr as the market leader in wafer-level burn-in for silicon photonics transceivers, creating a meaningful long-term growth driver.
