Conflict Minerals Policy Statement

AAON, Inc., including its subsidiaries, is committed to ethical business practices and compliance with applicable laws and regulations.

In July 2010, the United States passed the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank”). In August 2012, as directed by Section 1502 of Dodd-Frank, theU.S. Securities and Exchange Commission (“SEC”) adopted final rules regarding ConflictMinerals (the “Conflict Minerals Rule”). “Conflict Minerals” refers to gold, tin, tantalum and tungsten, as well as the derivatives of cassiterite, columbite-tantalite and wolframite, regardless of where they are sourced.

The Conflict Minerals Rule requires publicly traded companies and their suppliers to report annually on the presence of Conflict Minerals in the products they manufacture, and to demonstrate the proper level of due diligence in determining whether such Conflict Minerals originate from an area described as the “Covered Countries” (which is defined as the DemocraticRepublic of Congo and adjoining countries).

AAON does not directly source any of these materials, but does use refined metals in the manufacturing of its products. As a result, suppliers of metals used in the manufacture of AAON products (specifically gold, tin, tantalum, and tungsten) must demonstrate that they understand the Conflict Minerals Rule and will not knowingly procure specified metals that originate from any of the Covered Countries.

AAON will perform regular due diligence with its suppliers to verify compliance with theConflict Minerals Rule and will take appropriate actions in the event any of its suppliers fail to comply with the Conflict Minerals Rule.

AAON suppliers and other interested third parties may contact us at with any questions or for more information.
