Wendell Huang - VP & CFO
Thank you, Jeff. Good afternoon, everyone. Thank you for joining us today. My presentation will start with the financial highlights for the first quarter 2023. After that, I will provide the guidance for the second quarter 2023.
First quarter revenue decreased 18.7% sequentially in NT or 16.1% in U.S. dollar as our first quarter business was impacted by weakening macroeconomic conditions and softening end market demand, which led customers to adjust their demand accordingly. Gross margin decreased 5.9 percentage points sequentially to 56.3%, mainly reflecting lower capacity utilization and a less favorable foreign exchange rate, partially offset by a more stringent cost controls.
Total operating expenses accounted for 10.8% of net revenue, which is lower than the 12% implied in our first quarter guidance mainly due to stringent expense control and lower employee profit sharing. Operating margin was 45.5%, down 6.5 percentage points from the previous quarter.
Overall, our first quarter EPS was TWD 7.98 and ROE was 27.5%. Now let's move on to revenue by technology. 5-nanometer process technology contributed 31% of wafer revenue in the first quarter, while 7-nanometer accounted for 20%. Advanced Technologies, defined as 7-nanometer and below, accounted for 51% of wafer revenue.
