CA Supply Chain Act

Pella Corporation supports the California Transparency in Supply Chains Act of 2010.

Pella Corporation expects its suppliers to have commitment to social responsibility. This would
include sustainable environmental programs to benefit their community and the society at large,
adherence to internationally recognized child labor laws, and practicing diversity and respect
within the workplace. These values and expectations are specifically stated in Pella’s Supply
Management Policies. Pella Corporation’s Purchase Order Terms and Conditions require that all
suppliers adhere to applicable laws, including those relating to human trafficking in any form.

Pella Corporation regularly reviews its supply chain to consider risks and compliance
with both applicable laws and Pella Corporation’s policies and standards. We do not use third
parties to conduct such review. Pella Corporation’s Purchase Order Terms and Conditions give
us the right to audit our suppliers. We do not routinely conduct independent, unannounced
audits of our suppliers but may do so if we have cause to believe they are not in compliance.
Pella Corporation requires its suppliers to warrant that materials comply with the laws regarding
slavery and human trafficking. Our stated policies together with the Purchase Order Terms and
Conditions clearly communicate to suppliers that Pella will not do business with them if they fail
to adhere to such laws. Pella Corporation’s standards and values are incorporated into all
training of employees and managers who have responsibility for supply chain management.
