The reasons the company gives
The company's own explanation, not something inferred from the numbers.Net sales increased on growing demand for exhaust-gas valves for the marine market, price revisions and a focus on higher-value-added products. On the profit side, higher raw material prices and manufacturing costs, SG&A expenses including personnel and R&D costs, foreign exchange losses caused by the weaker yen, and the absence of the previous fiscal year’s gain on the sale of securities weighed on profit.
