Reorganization of the wheel business in China
In response to production downsizing caused by the declining market share of Japanese automobile manufacturers in China, the steel wheel production site in Guangzhou, Guangdong Province will be closed, and its equity interest will be transferred to a domestic Chinese company in February 2026.
We plan to strengthen competitiveness through initiatives such as enhancing technical support for aluminum wheel production sites that are equity-method affiliates, alongside consolidating steel wheel operations at the Fujian site, with the goal of rebuilding our China business.
Topy Autoparts Co., Ltd. Wholly owned subsidiary Fuzhou, Fujian

Guangzhou Wheelhorse Asahi Aluminium Co., Ltd.
Equity-method affiliate (49%) Guangzhou, Guangdong Province Aluminum wheel production site
Guangzhou Dicastal Asahi Aluminium Co., Ltd.
Equity-method affiliate (25%) Yingde City, Guangdong Province Aluminum wheel production site
Supplying locally while also providing cost-competitive aluminum wheels to Japan
Point！ Market share of Japanese automobile manufacturers in China: 9%
In China, new energy vehicles (NEVs) account for roughly 40% of total sales, and Japanese automobile manufacturers continue to face difficulties.
Restructuring of the U.S. business
Restructuring of the U.S. subsidiary, which has been experiencing poor business performance due to rising labor costs and declining productivity, is yielding progress in profitability.
Expand sales to local manufacturers in the U.S.

To meet the increasing demand for better-designed and larger-diameter products, TOPY INDUSTRIES KYUSHU has upgraded its painting line, with full-scale operations beginning in November 2025.
The new line, capable of handling sizes up to 24 inches, will enhance product value through superior paint quality.
Promotion of new process development
Construction machinery wheel business
We have revamped the tack welding machine for construction machinery wheels (SW) with fully automated, non-contact operation to boost efficiency and ensure worker safety.
Full-scale implementation is scheduled for FY2026.
Construction machinery undercarriage business
Automated bolt-and-nut tightening has been implemented in the track assembly process.
Through DX (image processing) and robotics, challenges such as bolt-and-nut posture alignment and assembly cycle time have been addressed.
Linking to the front-end automated track shoe loading device has improved efficiency; full operation will commence shortly.
