Hello, the company's external legal documents must be signed by the legal representative or the person authorized by the legal representative, but they must be stamped with the official seal to be effective on behalf of the company.

According to what you said, we think that if the official seal is true, the statement will have the effect of representing the company. Even if the official seal is forged, don't worry too much. We can also ask the other party for settlement through the actual project results.
