AEHRAehr Test Systems, Inc.
Is it safe?
Accounting red flags: accounting red flags, quality weak, and heavy debt (CCC). Everything else is secondary until this clears.
Financially healthy, low distress risk Altman Z-score, a bankruptcy-risk model from five balance-sheet ratios.
Several accounting flags in the manipulation-likely range Beneish M-score, a forensic model that detects earnings-manipulation patterns (receivables outrunning sales, margins slipping, accrual-heavy profit).
Weak, deteriorating fundamentals Piotroski F-score, nine pass/fail tests of year-over-year financial health across profitability, balance sheet and efficiency. 7 to 9 is strong, 0 to 3 weak.
Insiders were net sellers (-$18.9M, 90 days to Oct 8, 2026), selling is often routine.
Debt against weak or negative operating profit. A rule of thumb on leverage, not a credit rating.
Large price swings, high volatility. Worst drawdown -87% · now 42% below its 52-week high.
Unless marked, from SEC EDGAR, as of May 30, 2025.
Against the whole market›
Percentile against every name Ryufin tracks. Higher is better; the tick marks the middle of the market. Context, not one of the checks above.
Where this answer is blind. Altman sits structurally low for utilities and pipelines; Beneish runs high for fast growers, since sales growth alone lifts it; banks and REITs are excluded.
