convertible senior notes financial

"pricing of its private offering of $1.3 billion aggregate principal amount of 0% Convertible Senior Notes"

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 of 1933"

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

"use a portion of the net proceeds from the offering to pay the approximately $61.2 million cost of the convertible note hedge transactions"

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

"net proceeds to onsemi 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.

senior unsecured obligations financial

"The notes will be onsemi’s senior unsecured obligations and will be guaranteed"

Senior unsecured obligations are loans or bonds that a company promises to pay back with its own money, but without any special guarantees or collateral. If the company runs into financial trouble, these debts are paid after other debts with priority, meaning they are less protected but still important. They matter because they show how risky it is to lend money to a company.

fundamental change regulatory

"If onsemi undergoes a fundamental change (as defined in the indenture governing the notes)"

A fundamental change is a major shift in how a company or economy operates, like a new technology or a big change in leadership. It matters because such changes can affect the value or stability of investments, making them more or less attractive. Think of it like a major upgrade or shift in the rules of a game that can change the outcome.

strike price financial

"The strike price of the warrant transactions will initially be $211.54 per share"

The strike price is the fixed price at which an option gives its holder the right to buy or sell an underlying stock. Think of it like a coupon that lets you transact at a pre-agreed price regardless of the market; for investors it determines whether an option will be profitable, influences potential gains or losses, and is a key factor in the option’s market value and risk profile.

SCOTTSDALE, Ariz., May 06, 2026 (GLOBE NEWSWIRE) -- ON Semiconductor Corporation (Nasdaq: ON) (“onsemi”) announced today the pricing of its private offering of $1.3 billion aggregate principal amount of 0% Convertible Senior Notes due 2031 (the “notes”) at an approximately 52.5% premium to the closing price of onsemi’s common stock on May 6, 2026 of $105.77 per share. The notes were 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 has granted 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. The offering of the notes and the convertible hedge and warrant transactions described below are expected to close on May 11, 2026, subject to customary closing conditions.

onsemi expects the net proceeds from the offering of the notes to be approximately $1,276.4 million (or approximately $1,472.9 million if the initial purchasers exercise their option to purchase the additional notes in full) after deducting the initial purchasers’ discounts and after deducting offering expenses payable by onsemi. onsemi intends to use a portion of the net proceeds from the offering to pay the approximately $61.2 million 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). In addition, onsemi expects to use approximately $331.9 million of the net proceeds from the offering to repurchase approximately 3.1 million 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. onsemi expects to use 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 will not bear regular interest, and the principal amount of the notes will not accrete. Any special interest will be payable semiannually in arrears on May 1 and November 1 of each year, beginning on November 1, 2026 (if and to the extent that special interest is payable). The notes will mature on May 1, 2031, unless earlier repurchased, redeemed or converted. The initial conversion rate is 6.1997 shares of common stock per $1,000 principal amount of notes, which is equivalent to an initial conversion price of approximately $161.30 per share, representing a premium of approximately 52.5% over the closing price of the common stock of $105.77 per share on May 6, 2026. 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 concurrent repurchases described above may have affected the market price of the common stock concurrently with, or shortly after, the pricing of the notes, which may have resulted in a higher initial conversion price for the notes.

onsemi may redeem for cash all or any portion of the notes, at its option at any time and from time to time, on or after May 7, 2029 if the last reported sale price of onsemi’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading-day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which onsemi provides the related notice of redemption at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date. No sinking fund is provided for the notes. If onsemi undergoes a fundamental change (as defined in the indenture governing the notes), holders may require onsemi to repurchase for cash all or part of their notes at a repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the fundamental change repurchase date.

In connection with the pricing of the notes, onsemi has entered into privately negotiated convertible note hedge agreements with certain of the initial purchasers of the notes or their respective affiliates and 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 has entered 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. The strike price of the warrant transactions will initially be $211.54 per share, which represents a premium of 100.0% over the closing price of onsemi’s common stock of $105.77 per share on May 6, 2026 and is subject to certain adjustments under the terms of the warrant transactions. 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 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.
