IMPRO PRECISION (01286) saw its shares fall by nearly 6% in Hong Kong trading. At the time of writing, the stock was down 4.76% to HK$8, with a turnover of HK$21.85 million. The company recently released its annual results, reporting revenue of HK$5.096 billion, a year-on-year increase of 8.72%, and a profit attributable to shareholders of HK$726 million, up 12.71% compared to the previous year. A notable highlight was the strong performance of its high-horsepower engine business, which benefited from the rapid expansion of the global AIDC market. Revenue from this segment surged 43% year-on-year to HK$1.126 billion, accounting for 22% of total revenue. However, Jefferies noted in a research report that the stock's volatility following the earnings release may be linked to a slowdown in high-horsepower engine business revenue growth in the fourth quarter. Management attributed this slowdown to customer destocking activities at year-end. The company has observed that growth momentum resumed in January and February of this year. IMPRO PRECISION has provided guidance for full-year 2026 revenue growth of approximately 15% year-on-year.
