## Questions

### Who runs investment decisions at Aehr Test Systems?

As a publicly traded corporation, capital allocation decisions are made by Gayn Erickson as CEO alongside the board of directors. Erickson has held the chief executive role since 2012 and has driven the strategic pivot toward silicon carbide test equipment that defines the company's current posture. The firm's R&D spend and capacity expansion plans are approved through standard corporate governance channels.

### How does Aehr Test Systems source its equipment orders?

Aehr's customer relationships are deeply embedded in the semiconductor procurement cycle — automakers and Tier 1 suppliers specify the Fox-XP platform directly within their device qualification flows. The company also uses an equipment leasing program to seed adoption, allowing device makers to run production-validated output on a Fox-XP before committing to a multi-system purchase. Referral from existing customers within the tight-knit SiC ecosystem drives the majority of new business.

### Does the wealth come from a single family or operating business?

There is no underlying family wealth. Aehr Test Systems generates its balance sheet through operating revenue from semiconductor manufacturers who purchase its wafer-level burn-in and test equipment. The company has been listed on public markets for decades and has no single-family controlling shareholder.

### What is Aehr's known posture on acquisitions or external investments?

Aehr has historically grown organically by extending its Fox-XP platform into adjacent semiconductor materials like silicon carbide and gallium nitride rather than through acquisition. The company has not disclosed a dedicated corporate venture arm or M&A strategy, focusing internal capital on R&D for its core wafer-level test technology.

### Which sectors does Aehr explicitly avoid?

Aehr does not participate in conventional packaged-part semiconductor test — that segment is dominated by large automated test equipment (ATE) players like Teradyne and Advantest. The firm also does not offer system-level test for consumer electronics or memory, having exited legacy memory burn-in markets to focus entirely on wafer-level reliability screening for wide-bandgap power semiconductors and silicon photonics.
