#### News Release

#### onsemi Announces Proposed Private Offering of $1.3 Billion of Convertible Senior Notes
**SCOTTSDALE – May 6, 2026** – ON Semiconductor Corporation (Nasdaq: ON) ("onsemi") announced today that it intends to offer, subject to market and other conditions, $1.3 billion aggregate principal amount of Convertible Senior Notes due 2031 (the "notes") in a private offering. The notes will be offered only to persons reasonably believed to be qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"). onsemi also expects to grant to the initial purchasers of the notes an option to purchase, within a 13-day period beginning on, and including, the date on which the notes are first issued, up to an additional $200.0 million aggregate principal amount of the notes.

onsemi intends to use the net proceeds from the offering (i) to pay the cost of the convertible note hedge transactions described below (after such cost is partially offset by the net proceeds to onsemi from the sale of the warrant transactions described below), (ii) to repurchase up to $400.0 million of shares of onsemi's common stock, par value $0.01 per share (the "common stock"), concurrently with the pricing of the offering in privately negotiated transactions effected with or through one of the initial purchasers or its affiliate and (iii) the remainder of the net proceeds for general corporate purposes, including the repayment of outstanding indebtedness. If the initial purchasers exercise their option to purchase additional notes, onsemi expects to enter into additional convertible note hedge transactions and warrant transactions, and intends to use a portion of the net proceeds from the sale of any such additional notes to pay the cost of such additional convertible note hedge transactions (which would be partially offset by the net proceeds to onsemi from the sale of additional warrant transactions).

The notes will be onsemi's senior unsecured obligations and will be guaranteed by certain of its subsidiaries. The notes are expected to pay interest semiannually in arrears and to mature on May 1, 2031, unless earlier repurchased, redeemed or converted. onsemi will satisfy any conversion elections by paying cash up to the aggregate principal amount of the notes to be converted, and paying or delivering, as the case may be, cash, shares of common stock or a combination of cash and shares of common stock, at onsemi's election, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the notes to be converted. The initial conversion rate and other terms of the notes will be determined by negotiations between onsemi and the initial purchasers of the notes. The concurrent repurchases of common stock described above could affect the market price of the common stock concurrently with, or shortly after, the pricing of the notes and could result in a higher effective conversion price for the notes.

In connection with the pricing of the notes, onsemi expects to enter into privately negotiated convertible note hedge agreements with certain of the initial purchasers of the notes or their respective affiliates and/or certain other financial institutions (the "hedge counterparties"). The convertible note hedge transactions will cover, subject to customary anti-dilution adjustments, the number of shares of common stock that initially underlie the notes, and are expected to reduce the potential dilution to the common stock and/or offset potential cash payments in excess of the principal amount upon conversion of the notes.

onsemi also expects to enter into warrant transactions with the hedge counterparties relating to the same number of shares of common stock, subject to customary anti-dilution adjustments. The warrant transactions could have a dilutive effect on the common stock to the extent that the market price per share of the common stock exceeds the strike price of the warrants on the applicable expiration dates. If the initial purchasers exercise their option to purchase additional notes, onsemi expects to enter into additional convertible note hedge and warrant transactions.

In connection with establishing their initial hedge of the convertible note hedge and warrant transactions, the hedge counterparties, or their affiliates, expect to purchase shares of the common stock and/or enter into various derivative transactions with respect to the common stock concurrently with or shortly after the pricing of the notes. These activities could have the effect of increasing, or reducing the size of any decline in, the market price of the common stock or the notes at that time. In addition, the hedge counterparties, or their affiliates, may modify their hedge positions by entering into or unwinding various derivative transactions with respect to the common stock and/or by purchasing or selling the common stock or other securities of onsemi in secondary market transactions following the pricing of the notes and prior to the maturity of the notes, and are likely to do so during any observation period related to a conversion of notes. The effect, if any, of these activities on the market price of the common stock or the notes will depend in part on market conditions and cannot be ascertained at this time, but any of these activities could cause or prevent an increase or decline in the market price of the common stock or the notes, which could affect holders' ability to convert the notes and, to the extent the activity occurs during any observation period related to a conversion of notes, it could affect the amount of cash and the number and value of shares of the common stock, if any, that holders will receive upon conversion of the notes.

The notes, guarantees and any shares of the common stock issuable upon conversion of the notes have not been registered under the Securities Act or under any U.S. state securities laws or other jurisdiction and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.

This press release is neither an offer to sell nor a solicitation of an offer to buy any of these securities nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or jurisdiction.
