Kohjin Bio H1 FY3/2027 earnings summary

China OEM media fall far short

Kohjin Bio Co., Ltd. (TSE: 177A) reported consolidated results for the first half of FY3/2027, April 1 to September 30, 2026, on November 12, 2026. China's regulations on the clinical research and application of new biomedical technologies took effect in May 2026, and medical institutions there that buy its products stopped providing cell therapy, so sales of OEM culture media for China fell well below plan. Tissue Culture sales fell 28.2% to ¥920 million and segment profit 47.6% to ¥263 million. Fewer Chinese visitors to Japan, amid travel restraint and reduced flights, also cut the number of patients receiving self-paid cell therapy at its Japanese customers.

Microbiology, which makes bacterial-test media used in drug-makers' quality testing, saw sales fall 10.0% to ¥618 million, broadly in line with plan, and narrowed its loss to ¥32 million. Cell Processing sales fell 23.6% to ¥410 million and the segment swung to a ¥59 million loss: related products beat plan, but contract processing fell short and its cost exceeded contract revenue. Total assets were ¥9,047 million and the equity ratio 64.9%.
