MIRMMirum Pharmaceuticals, Inc.
Is it safe?
Forensics clean, with a caveat: a safe balance sheet, but heavy debt (CCC).
Financially healthy, low distress risk Altman Z-score, a bankruptcy-risk model from five balance-sheet ratios.
Insiders were net sellers (-$10.8M, 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.
Moderate price swings, typical volatility. Worst drawdown -64% · now 30% below its 52-week high.
Unless marked, from SEC EDGAR, as of Dec 31, 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.
