SK Hynix Inc. today announced financial results for its first quarter 2015 ended March 31, 2015.

Nevertheless, year-on-year the revenue rose 29% as well as operating profit totaled 1.59 trillion won increased 50%.

Operating margin for the quarter was 33% improved from 32% of the previous quarter and 28% of the last year thanks to elevated cost efficiency through enhanced products portfolio and yield rate. Net income amounted to 1.3 trillion won with net margin of 27% reflecting income tax expenses.

Quarter-over-quarter, DRAM bit shipment and the average selling price decreased 5% and 4% respectively.
