The AI test opportunity is the main new growth lever, but the base business remains tied to the EV power semiconductor cycle. ## Quote | Field | Value | | --- | --- | | Price (EOD close) | $53.57 | | Change 1d | +8.97% | | Change 7d | -2.40% | | Change 30d | -38.57% | | Change 1y | +118.83% | | 52-week high | $145.61 | | 52-week low | $19.40 | | Market cap | $1.7B | | P/E | n/a | | EPS | $-0.23 | | Next earnings | 2026-11-02 | Quote as of 2026-11-06. ## Company | Field | Value | | --- | --- | | Exchange | NASDAQ | | Sector | Technology | | Headquarters | Fremont, California | | CEO | Gayn Erickson | | Employees | 138 | | Website | https://www.aehr.com | | Buildout layers | [Chip Equipment & Foundries](https://supercyclehq.com/category/chip-equipment) | ## What the company does Aehr Test Systems makes semiconductor test equipment, specifically wafer-level burn-in systems that stress chips before they ship to catch early failures. It earns revenue selling these systems and their consumable WaferPak contactors to chipmakers. Its product line includes the FOX-XP test platform, WaferPak burn-in contactors, and systems for testing silicon carbide and gallium nitride devices. That SiC and GaN focus ties it to power chips for electric vehicles and AI power infrastructure, and it is now expanding into burn-in for AI processors. Founded in 1977 and headquartered in Fremont, California, Aehr trades on the NASDAQ and employs about 138 people. ## Role in the AI buildout Aehr sits in the Chip Equipment & Foundries layer of the buildout on the test and reliability side. Its wafer-level burn-in systems historically served silicon carbide chips for EVs, and the company is now extending the same approach to AI processors, which is its main new growth lever. The base business still follows the EV power semiconductor cycle, so Supercycle scores its AI exposure at 35 out of 100. ## Recent news - [Aehr Stock Jumps Into Focus After Earnings Beat And Higher Revenue Outlook](https://finance.yahoo.com/markets/stocks/articles/aehr-stock-jumps-focus-earnings-151728257.html?.tsrc=rss) (source, 2026-11-05) - [Aehr Test Systems (AEHR) Stock Sees Modest Fair Value Cut As Analysts Trim Multiples](https://finance.yahoo.com/markets/stocks/articles/aehr-test-systems-aehr-stock-011116262.html?.tsrc=rss) (source, 2026-11-05) - [Is Aehr Test Systems (AEHR) Priced For Perfection After 194% Run?](https://finance.yahoo.com/markets/stocks/articles/aehr-test-systems-aehr-priced-190834773.html?.tsrc=rss) (source, 2026-11-04) - [AEHR Stock Jumps as Aehr Systems Reports Blockbuster Q3 Revenue](https://www.barchart.com/story/news/8644575/aehr-stock-jumps-as-aehr-systems-reports-blockbuster-q3-revenue?.tsrc=rss) (source, 2026-11-04) - [Aehr Test Systems (AEHR) (Q1 2027) Earnings Call Highlights: Record Revenue, Raised Guidance ...](https://finance.yahoo.com/markets/stocks/articles/aehr-test-systems-aehr-q1-050209271.html?.tsrc=rss) (source, 2026-11-04) ## FAQ ### What does Aehr Test Systems do?
