Item 1.01

Entry into a Material Definitive Agreement

On September 23, 2025, Semiconductor Components Industries, LLC, a wholly-owned subsidiary (“SCI LLC”) of ON Semiconductor Corporation (“onsemi”), entered into a Master Framework Agreement (the “Master Framework Agreement”) with Ningbo Aura Semiconductor Co., Ltd., Aura Semiconductor Pvt. Ltd., Shaoxing Yuanfang Semiconductor Co. Ltd., Aura Semiconductor Limited and Aim Core Holdings Limited (collectively, the “Aura Entities”) whereby, among other things, SCI LLC will purchase certain assets of the Aura Entities and the Aura Entities will grant SCI LLC an intellectual property license for Vcore power management components and systems (the “Transaction”). Total consideration payable by SCI LLC with respect to the Transaction is a maximum of $144 million, subject to customary purchase price adjustments. Of this amount, $72 million is tied to the delivery and acceptance of specified products and the remaining $72 million is contingent upon the achievement of certain revenue milestones. The amount delivered at closing will depend upon the number of products delivered and accepted at closing.

Completion of the Transaction is subject to the satisfaction of customary closing conditions. Both SCI LLC and the Aura Entities are subject to certain restrictive covenants from the date of closing to December 31, 2030, and the Master Framework Agreement may be terminated under certain circumstances.

SCI LLC and the Aura Entities have each made customary representations, warranties, covenants and indemnities for a transaction of this type in the Master Framework Agreement.

The performance of all obligations and liabilities of the Aura Entities under the Master Framework Agreement and related ancillary agreements is jointly and severally guaranteed by certain individuals and affiliates of the Aura Entities.

In connection with the Master Framework Agreement, it is anticipated that SCI LLC and the Aura Entities will enter into a Support Services Agreement (the “Support Services Agreement”), pursuant to which certain of the Aura Entities will provide services to SCI LLC to facilitate the license and the orderly transfer of certain assets pursuant to the Master Framework Agreement. The Support Services Agreement shall be effective from the date of closing until December 31, 2030 and may be terminated under certain circumstances.

The foregoing descriptions of the Transaction, the Master Framework Agreement and the Support Services Agreement do not purport to be complete and are qualified in their entirety by reference to the Master Framework Agreement and the Support Services Agreement, which are attached to, and incorporated by reference into, this Current Report on Form 8-K (this “Form 8-K”) as Exhibit 10.1 and Exhibit 10.2, respectively. The Master Framework Agreement and the Support Services Agreement have been incorporated into this Form 8-K by reference to provide information regarding the respective terms and are not intended to modify or supplement any factual disclosures about SCI LLC or onsemi in any public reports filed with the Securities and Exchange Commission (the “SEC”) by onsemi.
