Will operating profit growth continue despite lower revenue? Verify the earnings mix in FY2027-H1

Revenue in FY2027 1Q was ¥7,382 million, down ¥950 million, or 11.4%, from ¥8,332 million in the year-earlier quarter. Operating profit, meanwhile, rose ¥169 million, or 9.9%, to ¥1,874 million from ¥1,705 million. The operating margin rose 4.9 percentage points, from approximately 20.5% to approximately 25.4%, indicating that the earnings mix shifted toward more profitable products rather than being driven by volume or overall revenue.

By business category, marine internal-combustion engine revenue was ¥2,811 million, down 39.7% year on year, while repair and parts revenue was ¥4,571 million, up 24.5%. The company attributed the decline in marine internal-combustion engine revenue to the allocation of part of its factory production line to demonstration operations for the first commercial hydrogen-fueled engine, as well as changes in the timing of revenue recognition resulting from customer-requested delivery schedules. Meanwhile, after-sales services supported by high vessel utilization, orders, manufacturing and sales by overseas licensees, key-component supplies and royalty income contributed to growth in repair and parts.

For FY2026 as a whole, marine internal-combustion engine revenue was ¥14,170 million, down 15.6% year on year, while repair and parts revenue was ¥15,536 million, up 28.6%. The company secured total revenue of ¥29,707 million and operating profit of ¥5,458 million. However, the company reports a single segment and has not disclosed operating profit, gross margin or the amount of profit contributed by licensing revenue for marine internal-combustion engines and repair and parts separately. It is therefore not yet possible to determine whether the 1Q margin improvement resulted from temporary revenue-recognition timing or product mix, or from a structural improvement in the profitability of after-sales services and licensing.

In FY2027-H1, the recovery in marine internal-combustion engine deliveries and the continuation of revenue growth in repair and parts need to be assessed separately. Key points will be how far marine internal-combustion engine revenue, which declined to ¥2,811 million in 1Q, recovers on a first-half cumulative basis, whether repair and parts revenue of ¥4,571 million can maintain its strong growth, and how the revenue mix and operating margin of the two categories change. If segment-level profit or the amounts attributable to changes in profit are disclosed with the first-half results, the repeatability of the latest operating profit growth can be assessed more specifically.
