Quality vs sector
—

This company's sector comes from its SIC code, unreviewed, or has too few comparable companies: we do not compare it with its sector.

Figures from the statements the company filed with the SEC (10-K, 10-Q). Free cash flow = operating cash flow − capital expenditures; empty if the company does not report capex. “Quality vs sector”: 0 to 100, the average of its percentiles in ROE, operating margin, free-cash-flow margin, revenue and earnings growth and net debt / EBITDA (at least 3 needed) against companies in its sector above $300M. How each figure is calculated

Earnings quality and debt

Operating cash flow ÷ net income (12 months)
1.76
Interest coverage (operating income ÷ interest)
360 timesfiscal 2025
Debt due within 12 months
$8.3M0.02 times cash and investments

From the figures the company filed with the SEC. Cash flow over net income near or above 1 means earnings are collected in cash; far below, that part is accounting. Coverage says how many times operating income pays the latest fiscal year's interest. Maturities come from the debt note of the latest annual report, counted from its closing date. “No data” never means zero.
