Koike-ya Q1 Net Profit Jumps 87% as Potato Yield Fix Cuts Costs

Koike-ya Inc. (TSE: 2226), the Japanese snack maker best known for potato chips and corn snacks and a consolidated subsidiary of Nissin Foods Holdings, reported consolidated first-quarter results for the three months to June 30, 2026 under Japanese GAAP. Revenue rose 2.0% to ¥15,316 million, operating profit climbed 33.6% to ¥936 million, ordinary profit gained 30.7% to ¥907 million, and net profit attributable to owners of the parent jumped 87.1% to ¥623 million.

Profit growth far outran the top line

The gap between the two lines is the striking feature of the quarter. A 2.0% revenue gain translated into a one-third rise in operating profit and near-doubling of the bottom line — a pattern that points to cost and mix effects rather than volume. Gross profit rose only modestly, to ¥3,660 million from ¥3,623 million, so the leverage came from further down the income statement and from the shift toward higher-priced products.

The potato-storage fix behind the margin

The single biggest contributor was an operational repair rather than a marketing win. Koike-ya had been losing value to deterioration in the quality of potatoes held in long-term storage — tubers harvested in one season and drawn down over many months, with the poorer ones trimmed away or rejected before they reach the fryer. In the quarter the company tightened monitoring of storage conditions from the growing region through to the factory and overhauled the warehouse environment itself, achieving a measurable quality improvement. Higher usable yield per tonne of raw potato cut unit costs materially and did most of the work behind the margin expansion.

Domestic: flat sales, sharply better profit

The domestic segment posted revenue of ¥13,597 million, up just 0.5%, but segment profit of ¥649 million, up 18.8% — the same flat-revenue, rising-profit shape as the group. The company has designated "continued expansion of high-value-added brands" and "stable potato procurement and quality improvement" as its two top priorities for FY3/2027. In the quarter it ran a "Godzilla" collaboration on the "Mucho" brand, with new products and limited-edition packaging that reached new customer groups and lifted brand-wide sales; renewed "Polinky" in April alongside a social-media promotion that drove strong sales; and grew "Scorn" sharply year on year, helped by a new television commercial featuring a popular male idol. Sales of the high-value-added "Koikeya Pride Potato" line continued to expand. Persistent inflation, compounded by heightened Middle East tension, kept input-cost pressure high, and the company is pursuing cost reduction across the group.

Overseas: the fastest-growing piece

Overseas revenue rose 15.7% to ¥1,718 million and segment profit 70.4% to ¥276 million, with aggressive expansion of launch areas and sales channels outpacing global cost inflation. Taiwan struggled against intensifying competition among major retailers and left revenue and profit roughly flat. Vietnam grew on continued strong exports plus momentum in the domestic modern-trade channel. Thailand grew on channel diversification and strong existing products. The U.S. business widened both its product range and its sales territory, beating budget on revenue and profit.

Balance sheet and guidance

Total assets stood at ¥46,832 million at June 30, down ¥531 million over the three months: construction in progress rose ¥308 million, while notes and accounts receivable fell ¥379 million and raw materials and supplies fell ¥319 million. Liabilities fell ¥692 million to ¥25,044 million as short-term borrowings dropped ¥500 million and the bonus provision fell ¥414 million, partly offset by a ¥373 million rise in accounts payable. Net assets edged up ¥161 million to ¥21,787 million, leaving an equity ratio of 45.7%. Full-year FY3/2027 guidance is unchanged from the forecast published on May 13, 2026; the company did not restate specific full-year figures in this filing. A special quarterly accounting treatment was applied for tax expense, with an estimated effective tax rate applied to pre-tax quarterly profit.
