Aehr Test Systems: what insiders have been doing
This page follows insider dealings at Aehr Test Systems as filed with SEC (Form 4), a company from the Technology sector based in Fremont, United States. 22 insiders have disclosed 243 filings since 18 October 2025.
Only sales appear on the open market, 60 sales in all totalling €49.5M, filed by 12 insiders. The largest single trade was a sale of €5.8M by Erickson Gayn, published on 14 April 2026, equal to 0.20% of the market capitalisation.
Compared with its exchange (5,812 companies, median 19 filings), a count of 243 filings is above the norm. Over the whole record (from 2021), the tally stands at 4 purchases and 159 sales. For the fiscal year to 29 May 2026, the annual 10-K puts revenue at 50.0 m USD and net income at -7.1 m USD.
Typically, a trade is published a median of 1 day after it takes place. The legal deadline for a Form 4 is two business days after the transaction. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.
In the same sector, recent insider purchases at Core Scientific, Inc./tx and Gitlab Inc. also feature in our signals. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.

About Aehr Test Systems
Aehr Test Systems is a United States-based company listed on the NASDAQ under the ticker AEHR. It is focused on semiconductor test, burn-in, and stabilization equipment, serving a highly specialized but strategically important niche in the chip supply chain. Headquartered in Fremont, California, in the heart of Silicon Valley, Aehr positions itself as a technology supplier that helps chip makers improve reliability before devices are deployed in demanding end markets. Its solutions are used for wafer-level, singulated die, and packaged-part testing.
The company has been active in semiconductor test and burn-in for more than four decades, giving it meaningful historical depth in a technically demanding segment. While the business is rooted in the United States, Aehr states that it has installed thousands of systems worldwide, indicating an international customer base and a broad geographic footprint. This global reach is important because its products are tied to worldwide investment cycles in semiconductors, electric vehicles, data centers, renewable energy, and artificial intelligence infrastructure.

Aehr’s core product families include the FOX-P platform and its FOX-XP, FOX-NP, and FOX-CP systems. These platforms are designed to test, burn in, and stabilize a wide range of devices, including silicon carbide power semiconductors, AI processors, memory chips, microcontrollers, sensors, system-on-chip devices, and photonic and optical devices. The company also sells complementary hardware such as WaferPak and DiePak products, plus loaders and aligners that support its test architecture. That product ecosystem is important because it gives Aehr an integrated offering rather than a single-point test tool.
From a competitive standpoint, Aehr operates in a market with high technical barriers, where performance, throughput, and reliability matter more than scale alone. Its competitive position is supported by proprietary know-how in massively parallel test and burn-in solutions, especially for advanced power semiconductors and emerging AI-related applications. Demand drivers highlighted by the company include electric vehicles, EV charging infrastructure, solar and wind power, computing, advanced AI processors, telecom and data infrastructure, and solid-state memory. In 2025, Aehr said it was expanding its total addressable market and diversifying its customer base, while also announcing orders related to AI processors and next-generation power semiconductor applications. For French-speaking investors, Aehr stands out as a US-listed NASDAQ technology specialist with exposure to semiconductor quality assurance, electrification, and AI-led infrastructure growth.
