Rishang Group: US Department of Commerce initiates circumvention investigation on certain steel wheels from Vietnam, potential adverse impact on subsidiary’s 2026 sales revenue

Rishang Group announced that on March 16, 2026, the US Department of Commerce initiated a circumvention investigation on steel wheels produced in Vietnam using Chinese hot-rolled steel and exported to the US. From January to September 2025, the sales revenue from Vietnamese subsidiary Xin Changcheng’s exports of 22.5-inch and 24.5-inch steel wheels accounted for less than 5% of the company’s unaudited operating income. Before a final ruling, US customs may suspend clearance and require prepayment of cash deposits, possibly causing downstream importers to halt imports, which could negatively affect the subsidiary’s 2026 sales revenue. However, it will not significantly impact the company’s overall operations or financial condition.

Yingxin Development (Rights Protection): Subsidiary’s final appeal maintains original judgment, litigation amount of 454 million yuan

As of the announcement date, other undisclosed lawsuits amount to 454 million yuan, accounting for 9.29% of the latest audited net assets.
