Cyberattack leaves timing and scope of impact of FY2027-H1 results announcement undetermined

The company suffered a cyberattack on 5 October 2026, causing system disruptions and postponing the announcement of its results for the second quarter of the fiscal year ending March 2027, originally scheduled for 9 November 2026. The post-postponement announcement date will be determined based on progress in restoring the overall system, and no specific date has been disclosed as of now. The company has also indicated that the announcement is expected to come more than 45 days after the end of the interim period. The next disclosure will therefore need to be reviewed not only for the announcement date but also for its relationship with the filing status of the semi-annual report.

The information released to date does not include FY2027-H1 revenue, operating profit, ordinary profit, net income or segment results. The postponement itself therefore does not support an inference of deteriorating results or an accounting problem. The preceding FY2027-Q1 recorded revenue of ¥12,024 million, operating profit of ¥545 million, ordinary profit of ¥808 million and net income attributable to owners of the parent of ¥355 million. In the next results announcement, it will be important to distinguish which processes, including order intake, manufacturing, shipping, customer acceptance and financial reporting, were affected by the system disruption, using these Q1 results as a reference point.

Regarding information leakage, it has been reported that electronic files suspected of having been leaked were posted online. An attack group claims to hold approximately 5.8 TB of data, but neither this volume nor the authenticity of all the data has been corroborated by a company announcement. The next disclosure should distinguish the external party's claims from facts confirmed by the company and clarify the types of files involved, whether personal information or business-partner information was included, and the status of the company's response to the Personal Information Protection Commission and the police.

The final issue for investors is not limited to when the results announcement will resume. The operating margin as of FY2027-Q1 was approximately 4.53%, and operating profit had reached 11.4% of the full-year plan of ¥4,800 million. If the cyberattack has resulted in additional costs, a period of business suspension, delays in revenue recognition or system recovery costs, it will be necessary to determine on an amount basis how these are reflected in operating expenses, extraordinary losses or revenue recognition in the following quarters.
