More about Aehr Test Systems
Revenue is primarily generated from system sales (capital equipment) plus recurring sales of proprietary contactors/carriers, spares, and related services.
Market Position
Aehr competes in reliability / burn-in and high-parallelism semiconductor test niches, differentiated by proprietary full-wafer contact (WaferPak) and integrated automation (e.g., WaferPak Aligners) that enable parallel test/burn-in of many devices simultaneously. It is expanding packaged-part reliability offerings for AI accelerators/HPC via the Sonoma family (from the Incal Technology acquisition).
Key Segments
Aehr’s portfolio centers on (1) wafer-level / die-level test & burn-in systems (FOX family) and (2) packaged-part reliability / burn-in systems (including Sonoma and Tahoe) with associated consumables (WaferPak/DiePak) and support services.

Change in closing price from the first day shown, or with Price the closing price itself. Prices: Yahoo Finance, to Nov 12, 2026. Dashed lines: the days the company released earnings (its SEC 8-K filings); EPS estimates: Yahoo Finance. The stock's move after a release runs from the last close before its day to the close the day after (or five days after), so a release before the open counts like one after the close.

Targets, ratings and earnings estimates: Yahoo Finance. Rating and target changes: Yahoo Finance's list of upgrades and downgrades. The average target on each day is the average of every listed firm's latest target set in the 180 days before it, so it counts fewer analysts than the average target above, and the band is the middle half of those targets (a quarter of the firms are above it, a quarter below); a target set before a stock split is divided by the split. Expected figures: the average of the analysts' estimates (Yahoo Finance). Their EPS is adjusted, as analysts estimate it, so it is set against the adjusted EPS Yahoo reports for the same quarters, not the GAAP EPS of the growth and valuation sections; revenue against the SEC filings. No change is given against a quarter whose reported EPS was more than 50% off its own estimate (often a one-off gain or charge), nor against a year that counts one. Each estimate is pinned to its fiscal period by the report date or the period's end, and one that cannot be is left out.
Financial health
Current ratio 10.3, no pressure to repay short-term debt; debt-to-equity 0.0, debt is very low and the balance sheet is solid.
Assets that can be turned into cash soon are 10.3x what is owed within a year. 1.5 or higher is comfortable; below 1 needs watching.
For every $1 of shareholder funds, there is $0.0 of debt (leases not counted). The higher the number, the more pressure when the economy weakens.
Cash and short-term investments of $116M and no debt. Lease obligations of $10M are not counted: they are rent owed, not money borrowed.

From the 13F filings of the 83 funds Hunch tracks, not of every institution: each fund's shares of AEHR at its latest quarter end against the quarter before, as filed (long positions only, options left out), the quarter before put on the latest quarter's share count across a split. A fund files 45 days after its quarter ends, so some have a newer quarter than others. Value is at the quarter end.
