Seoul, Jan 31 (IANS): Samsung Electronics said on Wednesday its fourth-quarter operating profit sank 34.4 per cent from a year earlier due largely to sluggish semiconductor business but its memory chip segment turned to the black on recovering demand.

The world's largest mobile phone and memory chip maker's operating profit amounted to 2.82 trillion won ($2.12 billion) for the October-December period, compared to 4.3 trillion won a year earlier, according to the company in a regulatory filing.

It is the first time that Samsung Electronics logged an annual operating profit of less than 10 trillion won since 2008, when the company recorded 6.03 trillion won in the midst of the global financial crisis.

Its net profit tumbled 73.4 percent on-year to 6.34 trillion won and sales decreased 3.8 percent to 67.77 trillion won.

Samsung Electronics said it has invested 7.55 trillion won into research and development for the quarter ending December, marking the largest quarterly investment, reports Yonhap news agency.

For all of 2023, Samsung Electronics posted 258.93 trillion won in sales, down 14.3 percent from a year earlier.

Its annual operating profit dived 84.9 percent on-year to 6.56 trillion won and net profit tumbled 72.2 percent to 15.48 trillion won.

It is the first time that Samsung Electronics logged an annual operating profit of less than 10 trillion won since 2008, when the company recorded 6.03 trillion won in the midst of the global financial crisis.

Samsung said its chip business earned 21.7 trillion won in sales for the three-month period through December, with an operating loss of 2.18 trillion won.

But the company said the DRAM business turned to a profit in the fourth quarter for the first time since the first quarter's loss.

It has experienced a rebound in demand for memory chips used in personal computers, mobile gadgets and generative AI servers, with decreasing inventories.

Increasing sales of premium products, including high bandwidth memory (HBM) chips and double data rate 5 (DDR5) products, lent support to the improved bottom line for the fourth quarter.

Its foundry, or contract chip manufacturing, businesses achieved a record number of orders in the quarter, but its earnings remained sluggish over the three-month period due to a global slowdown. The company did not provide exact figures.

Samsung Electronics' mobile and other device business posted 39.5 trillion won in sales and 2.6 trillion won in operating profit.

The smartphone segment saw its revenue and profit decrease due to lower smartphone sales in the fourth quarter, but demand for new tablet models and wearable products was solid over the cited period.

Earnings from the TV and home appliances business retreated due to intensified competition and waning market demand.

In the first quarter, Samsung Electronics is forecast to shift to a net profit in its memory chip business thanks to recovering demand for DRAM products. But the NAND flash memory sector is expected to remain in the doldrums.

Samsung said it will also make concerted effort to boost sales of its latest Galaxy S24 smartphones, the first on-device AI model launched earlier this month, to maintain the lead in the AI smartphone market.
