SECTION 1. CONFLICT MINERALS DISCLOSURE

Item 1.01. Conflict Minerals Disclosure and Report

Pursuant to Rule 13p-1 and Section 13(p) of the Securities Exchange Act of 1934, as amended, which implements Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Conflict Regulations”), ON Semiconductor Corporation (the “Company”) was required to make certain inquiries and perform certain due diligence with respect to any “conflict minerals” (as defined by paragraph (d)(3) of Item 1.01 of Form SD) that are necessary to the functionality or production of a product manufactured (or contracted to be manufactured) by the Company or any of its subsidiaries.

As a result of its inquiry, the Company determined that conflict minerals are necessary to the functionality of the Company’s products. After conducting a country of origin and a supply chain due diligence inquiry, the Company has been unable to conclusively determine that certain of its conflict minerals did not originate in the Democratic Republic of the Congo or an adjoining an country, or that such conflict minerals did not directly or indirectly finance or benefit armed groups in the Democratic Republic of the Congo or an adjoining an country. Accordingly, because of the foregoing determinations, the Company is describing its products as “DRC conflict undeterminable” as such designations exists under the Conflict Regulations.
