The revenue of intelligent networking delay management units increased by 54% in 2023, and there is plenty of room to replace electronic detonators overseas.
The company's subsidiary, Semikentuo's intelligent networking delay management unit, increased its revenue by 54% to 112 million yuan in 2023. The product realizes functions such as remote link, accurate delay, and remote detection in the Internet of Things, and is mainly used in digital electronic detonators. According to data from the China Blasting Industry Association, China's electronic detonators have basically been replaced; however, overseas electronic detonators are being promoted slowly, the penetration rate is low, and the market space is large.
Investment advice: The recovery in consumer electronics demand is compounded by the introduction of new products to maintain the “buy” rating. We expect the company's net profit to be 2.78/334/388 million yuan in 2024-2026 (value of 282/339 million yuan before 2024-2025). The PE corresponding to the stock price on April 15, 2024 is 20/16/14x, respectively. The company benefited from the recovery in consumer electronics demand and the smooth introduction of new products, maintaining a “buy” rating.
Risk warning: New product development falls short of expectations; customer verification falls short of expectations; demand falls short of expectations.
