JMS fell into a ¥783mn loss attributable to owners in the year to March 2026, reversing a ¥89mn profit a year earlier, according to its annual securities report. Net sales slipped to ¥65.85bn from ¥69.75bn, while ordinary income dropped to ¥356mn from ¥514mn.
The filing also shows basic loss per share of ¥31.97, compared with positive earnings per share of ¥3.65 a year earlier. That leaves JMS looking less like a business hit by a single bad quarter and more like one with profitability that has turned erratic: the same five-year summary includes a small ¥36mn loss in the year to March 2024 before last year's brief return to profit.
Sales, at least, have not collapsed across the whole period. JMS reported ¥58.17bn in net sales in 2022, climbing to last year's ¥69.75bn before slipping back this year. For readers, that makes the filing's main signal fairly plain: the sharper deterioration is in earnings, not simply in scale.
