In the past 5 years, revenue has grown for 4 years except for a significant decline of 41% in 2021, with an average growth rate of 25%. Operating profit fluctuated significantly due to gross margin fluctuations, resulting in a loss in 2021. Net income also experienced losses in 2018 and 2019, in addition to 2021, due to interest expenses. In 2022, interest expenses accounted for 19% of operating profit, indicating a heavy interest burden. The return on net assets is very high at 29.3%, but the previous profitability was low.
