United Microelectronics Corplooks reasonably valued for a mature semiconductor name, with FY 2025 EV/EBITDA at 5.05x, P/E at 15.09x, and P/S at 2.56x. Growth was mixed: revenue growth was 6.89%, but earnings growth declined by 13.31%, showing profits lagged sales.

Cash generation was a bright spot, as free cash flow growth surged 523.78%, even though free cash flow yield was only 0.06, which suggests the cash return to shareholders is still limited. Profitability stayed healthy, with gross margin at 29.01%, operating margin at 18.50%, and ROIC at 12.78%.

Overall, United Microelectronics Corpshowed solid operating efficiency and improved cash generation in FY 2025, but earnings growth weakened and valuation still reflects a business priced for steady rather than explosive expansion.
