Crispr Therapeutics prices upsized convertible senior notes offering

CRISPR Therapeutics (CRSP) announced the pricing of $550M aggregate principal amount of its convertible senior notes due 2031 in a private offering to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The Company also granted the initial purchasers of the notes an option to purchase, for settlement within a period of 13 days from, and including, the date the notes are first issued, up to an additional $50M aggregate principal amount of the notes. The sale of the notes is expected to close on March 16, 2026, subject to the satisfaction of customary closing conditions. The offering was upsized from the previously announced offering of $350M aggregate principal amount of notes. The notes will be senior, unsecured obligations of the Company. The investors in the notes agreed to an effective coupon of 1.125%. Because of anticipated 35% withholding on interest payments on the notes under Swiss tax law, the Company agreed to increase the coupon by 0.6058% to 1.7308% to effectively eliminate the impact of such anticipated withholding on any noteholders who are not eligible to receive a refund. Interest will be payable semiannually in arrears on March 1 and September 1 of each year, beginning on September 1, 2026. The notes will mature on March 1, 2031, unless earlier converted, redeemed or repurchased.
