Celcuity Inc. Announces Concurrent Public Offerings of Convertible Senior Notes Due 2031 and Common Stock

MINNEAPOLIS, July 28, 2025 (GLOBE NEWSWIRE) -- Celcuity Inc. (NASDAQ:CELC) (the "Company"), a clinical-stage biotechnology company pursuing development of targeted therapies for oncology, today announced proposed underwritten public offerings of $150,000,000 aggregate principal amount of its convertible senior notes due 2031 (the "Convertible Notes" and such offering, the "Convertible Notes Offering") and $75,000,000 of shares of its common stock (the "Common Stock" and, such offering, the "Common Stock Offering").

The Company intends to grant the underwriters of the offerings a 30-day option to purchase up to an additional $22,500,000 aggregate principal amount of Convertible Notes, solely to cover over-allotments, if any, in the Convertible Notes Offering, and a 30-day option to purchase up to an additional $11,250,000 of shares of Common Stock in the Common Stock Offering.

The Convertible Notes will be general, unsecured, senior obligations of the Company and interest will be payable semi-annually in arrears. The Convertible Notes will mature on August 1, 2031, unless earlier converted, redeemed or repurchased by the Company. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of 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.

The Company intends to use the net proceeds from the Convertible Notes Offering and the Common Stock Offering (i) to pay the cost of the capped call transactions described below, and (ii) the remainder for working capital and general corporate purposes, which may include clinical trial expenditures, commercial launch expenditures, research and development expenditures, capital expenditures, expansion of business development activities and other general corporate purposes.

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

In connection with the pricing of the Convertible Notes, the Company expects to enter into capped call transactions (the "capped call transactions") with one or more of the underwriters of the Convertible Notes or affiliates thereof and/or other financial institutions (the "option counterparties"). The capped call transactions will cover, subject to customary adjustments, the number of shares of the Common Stock initially underlying the notes. The capped call transactions are expected generally to reduce the potential dilution to the shares of the Common Stock upon any conversion of the Convertible Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted Convertible Notes, as the case may be, with such reduction and/or offset subject to a cap. If the underwriters exercise their over-allotment option, the Company expects to use a portion of the net proceeds from the sale of the additional Convertible Notes, to enter into additional capped call transactions with the option counterparties.

In connection with establishing their initial hedges of the capped call transactions, the Company expects the option counterparties and/or their respective affiliates will enter into various derivative transactions with respect to the Common Stock and/or purchase shares of the Common Stock concurrently with or shortly after the pricing of the Convertible Notes, including with, or from, as the case may be, certain investors in the Convertible Notes. This activity could increase (or reduce the size of any decrease in) the market price of the Common Stock or the Convertible Notes at that time.

In addition, the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to the Common Stock and/or by purchasing or selling the Common Stock or other securities of the Company in secondary market transactions following the pricing of the Convertible Notes and prior to the maturity of the Convertible Notes (and are likely to do so during the 50 trading day period beginning on the 51st scheduled trading day prior to the maturity date of the Convertible Notes, or, to the extent the Company exercises the relevant election under the capped call transactions, following any repurchase, redemption or conversion of the Convertible Notes). This activity could also cause or avoid an increase or a decrease in the market price of the Common Stock or the Convertible Notes, which could affect the holder's ability to convert the Convertible Notes and, to the extent the activity occurs during any observation period related to a conversion of the Convertible Notes, could affect the number of shares, if any, and value of the consideration that the holder will receive upon conversion of the Convertible Notes.

Jefferies, TD Cowen and Leerink Partners are acting as joint book-running managers for the Convertible Notes Offering and the Common Stock Offering. LifeSci Capital is acting as lead manager for the Convertible Notes Offering and passive bookrunner for the Common Stock Offering.
