Insights

onsemi plans a sizable $1.3B convertible note deal with hedges and buybacks.

onsemi is proposing $1.3 billion of senior unsecured convertible notes due 2031, plus an option for an extra $200 million. This raises long-term capital while deferring dilution decisions through a flexible cash-or-stock conversion settlement structure.

The company intends to use proceeds for convertible note hedge and warrant transactions, to repurchase up to $400.0 million of common stock at pricing, and for general corporate purposes including debt repayment. The hedge is designed to reduce dilution or excess cash outlay on conversion, while warrants and buybacks influence future share count dynamics.

Hedge counterparties may buy or sell stock and derivatives around pricing and during conversion observation periods, which the disclosure notes could affect trading prices of the stock and notes. Actual impact will depend on market conditions and future investor conversion behavior.

Convertible Senior Notes financial
"aggregate principal amount of Convertible Senior Notes due 2031"
Convertible senior notes are a type of loan that a company issues to investors, which can be turned into company shares later on. They are called "senior" because they are paid back before other debts if the company runs into trouble. This allows investors to earn interest like a loan but also have the chance to own part of the company if its value rises.
Rule 144A regulatory
"qualified institutional buyers in accordance with Rule 144A under the Securities Act"
Rule 144A is a regulation that makes it easier for companies to sell private bonds to large investors without going through all the usual rules that apply to public sales. It matters because it helps companies raise money more quickly and privately, often attracting big investors looking for special deals.
convertible note hedge transactions financial
"to pay the cost of the convertible note hedge transactions described below"
Convertible note hedge transactions are agreements made alongside convertible debt that limit the market impact when those notes convert into shares by using separate contracts that offset or neutralize the new stock issuance (for example, arranging share sales, purchases, or option contracts). Investors care because these hedges can reduce or delay dilution and dampen price swings—think of them like insurance that limits how much a conversion can dilute existing owners or move the stock price.
warrant transactions financial
"from the sale of the warrant transactions described below"
Warrant transactions are the issuance, sale, transfer, exercise or cancellation of warrants — contracts that give a holder the right to buy a company’s shares at a set price for a set period. Investors care because exercising warrants can raise cash for the company but also increase the number of shares outstanding, diluting existing ownership and potentially affecting the stock price; think of warrants like gift certificates that can be turned in later for a product at a fixed cost.
forward-looking statements regulatory
"This press release includes “forward-looking statements,” as that term is defined"
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

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.
