Samsung has revealed a sharp decline in profit for 2022, mainly due to the weak demand for its chips and smartphones, which are the company's main moneymakers. The Korean tech giant has posted KRW 302.23 trillion (US$245.4 billion) in annual revenue, which is a new record high for the company, in its latest earnings report. But it has also reported an operating profit of KRW 43.38 trillion (US$35 billion) for all of 2022, down KRW 8.5 trillion (US$6.9 billion) from the year before.
