SK hynix’s operating profit in 2019 plummeted 87 percent to 2.7 trillion won ($2.2 billion), amid the continued fall in memory chip prices and lower demand, the company said on Friday in its earnings report.

The world’s second-biggest memory provider raised 26.9 trillion won in annual sales last year, a 33.3 percent plunge from 2018. The net profit dived 87 percent to 2.02 trillion won for the whole year.

The company’s operating margin also dropped to 10 percent from 52 percent in 2018, it added.

In the fourth quarter, SK hynix marked an operating profit of 236 billion won, down 95 percent on-year. The sales during the October-December period also fell by 30 percent on-year to 6.93 trillion won. When compared to the third quarter, the sales were up 1 percent, but the operating profit fell by 50 percent.

The chipmaker swung to a deficit of 118.2 billion won in the final quarter, from a surplus of 3.39 trillion won a year earlier.

“The sluggish performance in the fourth quarter is attributed to the weak dollar, as well as costs spent on adjusting its production lines to produce 1y-nanometer DRAM and 96-layer NAND products,” said Vice President and CFO Cha Jin-seok.

The virus outbreak has caused no production disruptions at Hynix, which has a chip plant in the eastern Chinese city of Wuxi, but manufacturing could be hit if the situation was prolonged, Cha Jin-seo said.

SK hynix said global demand in the DRAM and NAND markets is expected to recover throughout the year, which could help the company restore its earnings.

This year, SK hynix plans to increase the proportion of 1y-nm products, while beginning mass-production of 1z-nm products within 2020. SK hynix will also aim to strengthen its foothold in the growing Low Power Double Data Rate 5 (LPDDR5) market.

In the NAND sector, SK hynix will ramp up the proportion of 96-layered products in its portfolio, while starting mass-production of 128-layer products this year.
