The reasons the company gives
The company's own explanation, not something inferred from the numbers.The main factors driving the increase in profit were higher demand, particularly related to AI servers and semiconductors, the benefits of switching to NXTR, and higher sales. These benefits were partially offset by higher material procurement prices, efforts to strengthen the production structure and overseas bases, and increases in research expenses, personnel expenses, packing and freight expenses, and other costs, which weighed on operating income.
