Kia Corp., South Korea's second-biggest carmaker, said Wednesday its fourth-quarter net profit rose 30 percent from a year earlier on a weak won and increased SUV sales.

Net profit for the three months ended in December jumped to 1.248 trillion won ($1.04 billion) from 961.6 billion won during the same period of last year, the company said in a statement.

"A combination of a weak won, improved product mix and reduced incentives helped offset the impact of chip supply chain problems and the coronavirus pandemic," the statement said.

But operating profit fell 8.3 percent to 1.175 trillion won in the fourth quarter from 1.282 trillion won a year ago due to one-off costs, such as research & development costs and bonuses for employees, it said.

Sales were up 1.6 percent to 17.188 trillion won from 16.910 trillion won during the same period.

For the whole of 2021, net income more than tripled to 4.760 trillion won from 1.488 trillion won a year earlier. Operating profit more than doubled to 5.065 trillion won from 2.066 trillion won during the cited period. Sales rose 18 percent to 69.862 trillion from 59.168 trillion won.

In 2022, Kia aims to achieve an operating profit of 6.5 trillion won on sales of 83.1 trillion won by focusing on SUV models and environment-friendly vehicles. (Yonhap)
