Classic Z factor contributions
X1 Working capital / assets
Short-term liquidity versus the size of the balance sheet.
0.951.2 × = 1.14X2 Retained earnings / assets
Cushion from years of profits. Share buybacks can push this negative at otherwise healthy firms.
−0.581.4 × = −0.82X3 EBIT / assets
Operating return on assets. Highest weight in the original model.
−0.253.3 × = −0.84X4 Book equity / liabilities
Book equity versus the liability stack. Mega-caps often look greyer here than they would if X4 used market cap.
23.190.6 × = 13.91X5 Sales / assets
Asset turnover — how much revenue the asset base supports.
0.001 × = 0.00
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
MBX Biosciences, Inc. is on classic Z at 13.40 (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.
