To uphold corporate compliance and support sustainable business development, Cornerstone has established dedicated whistleblowing channels. We encourage all employees, suppliers, agents, and other stakeholders to report—either anonymously or under their real names—any of the following violations or misconduct:

Scope of Key Reporting Areas:

1. Illegal or Unethical Conduct: Including but not limited to      commercial bribery, improper transfer of benefits, and misappropriation of      duties that violate laws and regulations.

2. Financial Misconduct: Such as falsification of financial      statements, accounting fraud, or embezzlement of assets that compromise      financial integrity.

3. Internal Control Deficiencies: Flaws that may lead to significant      operational risks or systemic failures.

4. Breaches of Business Ethics: Including but not limited to      disclosure of trade secrets, unfair competition, and false advertising.

5. Other Harmful Acts: Any behavior that may damage the      company’s reputation, investor interests, or long-term sustainability.

Our Commitments:

• All reports will be handled with strict      confidentiality.

• Whistleblowers’ legal rights and interests      will be protected in accordance with the law.
