Operating margin is operating income as a share of revenue. Free cash flow is cash from operations minus capital spending. Return on capital is after-tax operating income as a share of the money invested in the business: debt plus equity, minus cash.
About these figures. Tower Semiconductor is a foreign company: it files an annual report on Form 20-F, prepared under US accounting standards (US GAAP), instead of a 10-K, and no quarterly reports, so this page has fiscal years only. Its shares trade in the US as American depositary shares (ADSs), and one ADS can stand for several ordinary shares, so per-share figures are per ordinary share and the page has no market value, P/E or valuation model.

US$ millions unless stated, at each fiscal year end. Net debt to EBITDA is debt minus cash, divided by operating income before depreciation and amortization: roughly how many years of those earnings the net debt equals. Debt to equity is debt as a multiple of shareholders' equity. Interest coverage is operating income divided by interest expense. The current ratio is current assets over current liabilities; the quick ratio leaves out inventory.
Piotroski F-score
The F-score counts how many of nine simple tests of profitability, funding and efficiency a company passed in a year (Piotroski, 2000). The more tests passed, the stronger the year: 8 or 9 is strong, 0 to 2 weak. Companies that report no gross profit are scored on the other eight.
