Five-year path

Need two annual 10-Ks to draw a path. The desk will pull this issuer’s filings rather than invent a series.

Overview

rule-v1

TANTECH HOLDINGS LTD is on classic Z at 5.65 (safe) for FY2025, from an SEC 10-K. Book equity / liabilities is the line that sets the print. This is the first live year on the desk. No market tape loaded. Classic Z was fit on manufacturers; buybacks can send retained earnings negative at otherwise healthy issuers, and X4 is book equity, not market cap.

Book screen Safe; market PD —. Tape not priced — not a single default call.

Market DD · naive Merton

No market tape yet.

Pull a year of closes (Yahoo, Nasdaq if Yahoo is limited) and size equity from Nasdaq cap or EDGAR shares. Distance-to-default and 1-year PD stay blank until then.
