Dividend yield stands at 1.28%, reflecting moderate shareholder returns with some caution needed on payout sustainability.
Tower Semiconductor Ltd.
Tower Semiconductor presents a strong net margin (14.47%) and excellent interest coverage (31.57), but its high PE ratio (27.54) raises valuation concerns. The company has a very high current ratio (6.18), flagged as unfavorable possibly due to inefficient asset use. It does not pay dividends, likely reinvesting profits to support growth and R&D priorities.
Which one has the best ratios?
Both companies receive a slightly favorable global assessment, but STMicroelectronics benefits from more balanced valuation and dividend metrics, while Tower Semiconductor’s higher net margin contrasts with its elevated PE and liquidity imbalances. The choice depends on investor preference for valuation discipline versus growth reinvestment.
