Ionis announces proposed private placement of convertible notes

CARLSBAD, Calif., June 6, 2023 /PRNewswire/ -- Ionis Pharmaceuticals, Inc. (NASDAQ: IONS) announced today that it intends to offer, subject to market conditions and other factors, $500.0 million aggregate principal amount of Convertible Senior Notes due 2028 (the "notes") in a private placement (the "offering") to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"). Ionis also intends to grant the initial purchasers of the notes an option to purchase, within the 13-day period beginning on, and including, the first date on which the notes are issued, up to an additional $75.0 million principal amount of notes.

The notes will be general unsecured obligations of Ionis and will accrue interest payable semiannually in arrears. Upon conversion, Ionis will pay or deliver, as the case may be, cash, shares of its common stock or a combination of cash and shares of its common stock, at its election. The interest rate, initial conversion rate and other terms of the notes will be determined at the time of pricing of the offering.

Ionis expects to use a portion of the net proceeds from the offering to repurchase for cash certain of its 0.125% Convertible Senior Notes due 2024 (the "2024 notes") in privately negotiated transactions. Ionis expects to use the remaining net proceeds from the offering for additional repurchases of the 2024 notes from time to time following the offering, including the repayment of any remaining 2024 notes at maturity, and for general corporate purposes.

In connection with any repurchase of the 2024 notes, Ionis expects that holders of the 2024 notes who agree to have their 2024 notes repurchased and who have hedged their equity price risk with respect to such notes (the "hedged holders") will unwind all or part of their hedge positions by buying Ionis' common stock and/or entering into or unwinding various derivative transactions with respect to Ionis' common stock. The amount of Ionis' common stock to be purchased by the hedged holders or in connection with such derivative transactions may be substantial in relation to the historic average daily trading volume of Ionis' common stock. This activity by the hedged holders could increase (or reduce the size of any decrease in) the market price of Ionis' common stock, including concurrently with the pricing of the notes, resulting in a higher effective conversion price of the notes. Ionis cannot predict the magnitude of such market activity or the overall effect it will have on the price of the notes or Ionis' common stock.

The notes and any shares of Ionis' common stock issuable upon conversion of the notes have not been and will not be registered under the Securities Act, any state securities laws or the securities laws of any other jurisdiction, and unless so registered, may not be offered or sold in the United States absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws.

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 thereof under the securities laws of any such state or jurisdiction.
