Thank you, Jeff. Good afternoon, everyone, and thank you for joining us today. My presentation will start with financial highlights for the second quarter of 2023. After that, I will provide the guidance for the third quarter.
Second quarter revenue decreased 5.5% sequentially in NT or 6.2% in U.S. dollars as our second quarter business was impacted by the overall global economic conditions, which dampened the end market demand and led to customers' ongoing inventory adjustment.
Gross margin decreased 2.2 percentage points sequentially to 54.1%, mainly reflecting lower capacity utilization and higher electricity cost, partially offset by more stringent cost control and a more favorable foreign exchange rate.
Despite the industry's cyclical downturn, we continue to invest in R&D to support our N3 and N2 development. Thus, operating margin was 42%, down 3.5 percentage points sequentially. Overall, our first quarter EPS was NT7.01 and ROE was 23.2%.
Now let's move on to revenue by technology. 5-nanometer process technology contributed 30% of our wafer revenue, excuse m e, in the second quarter, while 7-nanometer accounted for 23%. Advanced technologies, defined as 7-nanometer and below, accounted for 53% of wafer revenue.
