Supplier Code of Conduct

LAST UPDATED: March 17, 2021

It is the intention of PDF Solutions, Inc. to select and retain suppliers (“Suppliers”) who share and embrace the letter and spirit of the Company’s commitment to integrity. The Company’s Code of Ethics is a general guide to PDF Solutions’ standards of business practices and regulatory compliance. Its requirements apply to PDF Solutions, Inc. and all subsidiaries, and to all directors, officers, and employees of each. All references to “PDF Solutions”, “the Company”, “we”, “us” or “our” include PDF Solutions, Inc. and all subsidiaries unless otherwise specified. When used in this document, “Suppliers” includes Suppliers’ Representatives, unless the context indicates otherwise. Suppliers’ employees, agents, and subcontractors shall hereinafter be referred to collectively as “Representatives.”

We understand that Suppliers are independent entities; however, the business practices and actions of a Supplier may impact and/or reflect upon PDF Solutions. Because of this, we require all Suppliers to adhere to standards of business conduct and compliance while they are conducting business with and/or on behalf of PDF Solutions, similar to what PDF Solutions expects from its own directors, officers, and employees, including as supplemented by the RBA Code of Conduct described below.

In addition, there may be other conduct not specifically listed that will be considered unacceptable for a Supplier. PDF Solutions requires that Suppliers conduct themselves in a professional manner at all times while on PDF Solutions property or while conducting business with and/or on behalf of PDF Solutions. Suppliers with questions regarding the standards for Suppliers should contact the Corporate Legal Department (“CLD”) of PDF Solutions at legal.department@pdf.com.

RBA CODE OF CONDUCT

The PDF Solutions’ Board of Directors recently adopted the Responsible Business Alliance (or RBA) (formerly, the Electronics Industry Citizenship Coalition or EICC) Code of Conduct to supplement our Code of Ethics, including the specific policies of the RBA Code relating to the five critical areas of corporate social responsibility: labor, health and safety, environment, management systems, and ethics. All PDF Solutions’ Suppliers will be required to inform their Representatives about the RBA Code of Conduct and, when appropriate, train them to ensure they understand and comply with it. We also expect PDF Solutions’ Suppliers to require their own suppliers to adhere to the RBA Code of Conduct. The RBA Code of Conduct is maintained by the RBA here.
