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).
