Proceeds to Advance Clinical Development of Gedatolisib
Including Forthcoming Phase 3 Clinical Study (VIKTORIA-1)

MINNEAPOLIS, MN / ACCESSWIRE / May 16, 2022 / Celcuity Inc. (Nasdaq:CELC), a clinical-stage biotechnology company pursuing an integrated therapeutic and companion diagnostic strategy for treating patients with cancer, today announced that it has entered into a definitive securities purchase agreement with certain institutional and other accredited investors in a private placement for the purchase of common stock, preferred stock that may be convertible into common stock and warrants initially exercisable for preferred stock that is expected to result in aggregate proceeds to the Company of $100 million, before deducting placement agent fees and other offering expenses. The Company expects to use the net proceeds to advance clinical development of gedatolisib, including its planned Phase 3 clinical study (VIKTORIA-1), and for general corporate purposes.

Venrock Healthcare Capital Partners is the lead investor in the private placement, and Commodore Capital, New Enterprise Associates (NEA), RA Capital Management, Soleus Capital and Brian Sullivan, the Company's Chief Executive Officer, are also participating. Investors will purchase shares of common stock and preferred stock at a price per share of $5.75 (on an as converted to common stock basis). For each share of common stock and each 1/10 of a share of preferred stock purchased, investors will receive a warrant initially exercisable for preferred stock equivalent to 0.40 shares of common stock on an as converted basis. The exercise price of the warrants will be at a 40% premium to the price paid by investors for the initial shares of common stock purchased in the private placement. The preferred stock will be convertible into common stock at the holder's election, subject to certain limitations such as beneficial ownership and the approval by the Company's stockholders to increase the number of authorized shares of common stock sufficient to cover the shares of common stock issuable upon conversion of (i) the preferred stock purchased in the private placement and (ii) the shares of preferred stock that may be issued upon exercise of warrants purchased in the private placement. The warrants are initially exercisable for preferred stock and will convert into warrants to purchase common stock if the proposed increase in the Company's authorized common stock is approved by stockholders.

The closing of the private placement is expected to occur shortly after the first patient enrolled in the Company's forthcoming Phase 3 clinical study (VIKTORIA-1) receives their first dose of treatment at a clinical site located in the United States, provided that such date must occur on or before December 31, 2022. The Company expects to activate the VIKTORIA-1 study in mid-2022 and that the first patient receiving their first dose is expected to occur six to ten weeks later. The Company expects to report results for the first primary analysis of the VIKTORIA-1 clinical study in the second half of 2024. Additional details regarding the private placement will be included in a Form 8-K to be filed by the Company with the Securities and Exchange Commission.

Jefferies LLC acted as the sole placement agent for the private placement.

About Celcuity

Celcuity is a clinical-stage biotechnology company seeking to extend the lives of cancer patients by pursuing an integrated therapeutic and companion diagnostic strategy. The company's lead therapeutic candidate is gedatolisib, a potent, reversible dual inhibitor that selectively targets all Class I isoforms of PI3K and mTOR. Its mechanism of action and pharmacokinetic properties are highly differentiated from other currently approved and investigational therapies that target PI3K or mTOR alone or together. The company expects to initiate a Phase 3 study evaluating gedatolisib in patients with HR+/HER2- advanced breast cancer in 2022. Its CELsignia companion diagnostic platform is uniquely able to analyze live patient tumor cells to identify new groups of cancer patients likely to benefit from already approved targeted therapies.
