Five9 Announces Exercise of the Option to Purchase Additional 1.00% Convertible Notes Due 2029

Five9, Inc. (NASDAQ: FIVN), the Intelligent CX Platform provider, today announced the exercise of the entire $97.5 million aggregate principal amount option to purchase additional 1.00% convertible senior notes due 2029 (the "notes") in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933 (the "Act"), resulting in a total offering size of $747.5 million. The notes to be sold in connection with the exercise of the option to purchase additional notes have the same terms in all respects as the other notes to be sold in the offering. The total offering of $747.5 million aggregate principal amount of notes is expected to settle on March 1, 2024.

The net proceeds from the sale of notes in connection with the exercise of the option to purchase additional notes is expected to result in approximately $95.3 million of additional net proceeds. Five9 expects to use a portion of the net proceeds from the sale of the additional notes to enter into additional capped call transactions with one of the initial purchasers in the offering and other financial institutions. The remainder of the additional net proceeds from the sale of the additional notes is expected to be used for working capital and other general corporate purposes.

The notes were and will be offered only to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Act. Neither the notes nor the shares of common stock issuable upon conversion of the notes, if any, have been, nor will be, registered under the Act or the securities laws of any other jurisdiction and may not be offered or sold in the United States absent registration or an applicable exemption from such registration requirements.

This announcement is neither an offer to sell nor a solicitation of an offer to buy any of these securities and shall not constitute an offer, solicitation, or sale in any jurisdiction in which such offer, solicitation, or sale is unlawful.
