Expanded Production Orders from Lead Silicon Carbide Customer, and Growing Engagement with Leading Automotive Suppliers Highlight Strengthening Silicon Carbide Market

FREMONT, CA / ACCESS Newswire / July 14, 2026 / Aehr Test Systems (NASDAQ:AEHR), a leading provider of test and burn-in solutions for semiconductor devices used in artificial intelligence (AI), silicon photonics, data center, automotive, and industrial applications, today announced it has received more than $8 million in new silicon carbide wafer-level burn-in (WLBI) orders.

The orders include a significant follow-on order for additional FOX WaferPak^™ full wafer Contactors from its lead silicon carbide production customer to support expanded manufacturing capacity for new electric vehicle platforms, particularly those serving the rapidly growing China electric vehicle market. The large WaferPak order reflects increased production activity and utilization at the customer, as demand for silicon carbide power devices continues to improve. In addition to these WaferPak orders, the customer indicated additional future capacity requirements beyond this order in Aehr's current fiscal year. Aehr also received a key order directly from one of the largest automotive companies in the world for multiple WaferPaks to be used in qualification of silicon carbide devices from suppliers for their new generation of electric vehicles using Aehr's FOX wafer level burn-in systems.

Gayn Erickson, President and CEO of Aehr Test Systems, commented, "We are very pleased to announce these new orders, which we believe reflect strengthening momentum in the power semiconductor WLBI market and the beginning of the next phase of growth for this portion of our business. Our lead silicon carbide production customer continues to expand capacity with additional WaferPak orders supporting new electric vehicle programs, particularly in China where electric vehicle adoption continues to accelerate.

"Perhaps even more encouraging is what we are seeing with the new WaferPak order directly from one of the top two leading automotive companies in the world that is using our FOX systems and proprietary WaferPaks to qualify the quality and reliability of multiple silicon carbide companies around the world for their planned electric vehicle expansions. We are actively engaged with several of the world's largest automotive companies, and with several leading silicon carbide device manufacturers who are supporting their next-generation electric vehicle platforms as they evaluate deploying WLBI in production. These companies recognize the increasing importance of screening for early-life failures at the wafer level, before packaging, to improve long-term reliability and reduce manufacturing costs. We believe these engagements represent significant future production opportunities for Aehr as WLBI continues to gain acceptance as a critical manufacturing step for high-reliability automotive power semiconductors.

"We also recently secured our first silicon carbide customer in Taiwan last quarter, expanding our presence in another key semiconductor manufacturing region for automotive and industrial applications. This customer works closely with several automotive manufacturers in Taiwan and China, as well as with other international companies.

"The outlook for electric vehicles continues to improve following a period of inventory adjustments across parts of the automotive market. Industry forecasts point to renewed growth in Europe, increasing electrification initiatives in Japan, and continued leadership by China, where electric vehicles now account for more than half of new passenger vehicle sales. At the same time, the transition toward higher-voltage vehicle architectures, faster charging systems, and improved drivetrain efficiency is increasing demand for advanced silicon carbide power semiconductors that require the highest levels of reliability.

"We are also seeing growing interest in WLBI from customers developing silicon carbide devices for industrial automation, renewable energy, energy storage, charging infrastructure, aerospace, and AI data center power systems. As these markets continue to expand and reliability requirements become increasingly stringent, we believe Aehr is uniquely positioned with the industry's most proven production WLBI solution.

"With an expanding installed base, a growing pipeline of production opportunities, and increasing engagement with both leading automotive suppliers and silicon carbide device manufacturers worldwide, we are excited about the opportunities ahead and believe we are well positioned to benefit as silicon carbide WLBI adoption accelerates."
