Hokkaidenko had a strong year to March 2026: net sales reached ¥72.45bn, ordinary profit ¥5.19bn, profit attributable to owners of parent ¥3.72bn, and total assets ¥55.20bn.
The annual report's five-year summary shows sales were ¥68.93bn a year earlier and ¥60.10bn two years earlier, while ordinary profit was ¥3.65bn last year and ¥3.04bn two years earlier. The filing does not say which projects drove the jump, but it does show a much stronger latest year on both revenue and earnings.
A separate internal-control report suggests the result remains concentrated in the parent company's core contracting operations. Hokkaidenko said the parent represents roughly 90% or more of consolidated sales, and it focused control testing on completed-work revenue, construction costs, receivables, work in progress, materials inventory, construction payables and provisions for construction-contract losses. Management judged financial-reporting controls effective at March 31.
One small consolidated subsidiary, equal to 0.9% of sales, was excluded from the company-wide control scope as immaterial. For readers tracking electrical-construction groups, the message is simple: a strong year, heavily anchored in the main business, with the finer detail on end-markets still missing from this packet.
