[4-connected board Dongan Power: Not engaged in the flying car business, only matching range extenders for customers’ flying cars under development] On October 21st, Dongan Power (600178.SH) announced that the company’s stock has been at the daily limit for 4 consecutive days since October 16, with a cumulative increase of 46.46%, but the fundamentals have not changed significantly. Recently, we have noticed that some media have listed the company as a flying car concept stock. We hereby clarify the following: The company is a listed company of auto parts. Its main business is the production and sales of automobile engines and transmissions. It is not engaged in the flying car business. It only matches the range extender for the flying car under development by the customer. This series of range extenders are the company's existing products and are currently mainly used for range extenders. For automobiles, this use of flying cars is a moderate expansion of existing product application scenarios. It only requires adaptive development and does not involve major technical changes. Currently, the product is still in the trial production and tooling prototype stage, and has not yet formed mass production. From January to September 2026, the business has not yet generated revenue, and there is great uncertainty in the subsequent business development.
