SAN DIEGO, Nov. 8, 2021 – Ensysce Biosciences, Inc. (“Ensysce” or the “Company”) (NASDAQ: ENSC, OTC: ENSCW), a clinical-stage biotech company with proprietary technology platforms to reduce the economic and social burden of prescription drug abuse and overdose, announced today that it has completed its previously announced private placement under a securities purchase agreement with institutional investors (“Investors”) for senior secured convertible notes (the “Notes”) and warrants exercisable for Ensysce common stock (the “Warrants”) for an aggregate investment of $15 million. The final funding by the Investors of $10 million, prior to fees and offering expenses, occurred on November 5, 2021.

The Notes are convertible into shares of Ensysce common stock at a conversion price of $5.87, a 30% premium to the base price set at the time of the initial closing. The Notes have a maturity date of 21 months from the applicable closing date and will bear interest from date of issuance at 5.0% per annum, with monthly principal payments in cash or common stock beginning approximately 90 days after the initial closing. The Notes were issued with an original discount of six percent (6%). The Warrants have the right to purchase shares of common stock at an exercise price of $7.63, a 30% premium to the conversion price. The Warrants are exercisable for five years following the date of issuance.

The total gross proceeds from the issuance of the Notes pursuant to the securities purchase agreement, totaling $15 million before fees and expenses, will be used for general working capital purposes. The first closing on September 24, 2021 provided $5 million of funding and the second closing on November 5, 2021 provided $10 million of funding. At the second closing, the Company issued to the institutional investors referenced above, (i) Notes in the aggregate principal amount of $10.6 million for an aggregate purchase price of $10 million and (ii) Warrants to purchase 722,317 shares of the Company’s common stock at an exercise price of $7.63.

“The completion of our financing provides us with additional and necessary proceeds to continue our advancement of our lead clinical trial programs, including completion of our PF614-102 bioequivalence study and our nasal and oral human abuse liability studies, as a well as to continue the clinical development of our overdose protection platform with our lead product PF614-MPAR,” said Dr. Lynn Kirkpatrick, CEO of Ensysce Biosciences. “We remain focused on our commitment to stem the prescription drug abuse epidemic by bringing our unique pipeline of products to the industry, which will ultimately provide safer options for both prescribers and patients.”
