FANCL stock: Data breach affects 368,184 members

FANCL disclosed on October 16, 2026, that unauthorized access to its e-commerce site had exposed member information. The disclosure, summarized by Japan IR, said 393,785 FANCL records covering 368,184 people were affected.

Data Breach Reaches FANCL Members

The affected information included email addresses, names, addresses, telephone numbers, dates of birth, gender and other membership details. Payment and transaction information was not affected, and the company said no significant operational impact had been confirmed at the time of the notice.

FANCL established an emergency response headquarters to prevent a recurrence. The company reported the incident to Japan's Personal Information Protection Commission and consulted with police. The impact on consolidated financial results remained under examination, with separate disclosure planned if a material effect is identified.

Delisting Limits Equity-Market Access

For investors, the incident has a different market context because FANCL shares were delisted from the Prime Market of the Tokyo Stock Exchange on December 18, 2024. FANCL's investor-relations page links the delisting to the company's transformation under its new ownership following Kirin's takeover.

The Nikkei 225 provides the broader Japanese equity-market context.
