Cogent intends to grant the underwriters a 30-day option to purchase up to an additional $30 million aggregate principal amount of Convertible Notes, solely to cover over-allotments in the Convertible Notes Offering, and a 30-day option to purchase up to an additional $30 million of shares of common stock in the Equity Offering.

The closing of neither the proposed Convertible Notes Offering nor the Equity Offering is conditioned upon the closing of the other offering. The proposed offerings are subject to market and other conditions, and there can be no assurance as to whether or when the proposed offerings may be completed, or as to the actual size or terms of the offerings.

The Convertible Notes will be general, unsecured, senior obligations of Cogent and interest will be payable semi-annually in arrears. The Convertible Notes will mature on November 15, 2031, unless earlier converted, redeemed, or repurchased by Cogent. Upon conversion, Cogent will pay or deliver, as applicable, cash, shares of its common stock or a combination of cash and shares of common stock, at its election. The interest rate, conversion rate, offering price and other terms are to be determined upon the pricing of the Convertible Notes.

Cogent intends to use the net proceeds from the proposed Convertible Notes Offering and the proposed Equity Offering to repay $50 million of loans outstanding under its existing term loan facility, plus accrued interest and associated fees, and the remainder for development and regulatory activities relating to bezuclastinib and other product candidates, the anticipated commercial launch and commercialization of bezuclastinib, as well as for working capital and general corporate purposes.
