CIEN Altman Z-score: 11.66.

TECHi computes a non-financial-company Altman-style score from working capital, retained earnings, EBIT, market value, liabilities, revenue, and assets. It is not a bankruptcy prediction, but it gives pro readers a fast stress screen that most quote pages do not show beside live valuation metrics.

Profitability read

CIEN converts 8.0% of revenue into net income.

Margins in the high single-digits to high-teens are the bulk of the index. The differentiated reads here are operating-margin direction (improving = leverage) and ROE — the latter tells you how much equity capital management actually needs.
