Why did Churchill's net profit surge in Q4 despite high expenses?

Churchill's net profit surged in Q4 despite high expenses due to a significant increase in revenue from its mobile games and advertising business. The company's continued improvement in commercialization efficiency led to a 26% year-on-year growth in net revenue, which was a key driver for the adjusted net income turning positive for the first time. This growth in revenue outweighed the impact of high expenses, resulting in a net profit surge.
