Nature of Business and Liquidity

Zynerba Pharmaceuticals, Inc., together with its subsidiary, Zynerba Pharmaceuticals Pty Ltd (“Zynerba”, the “Company”, “we”), is a clinical stage specialty pharmaceutical company focused on the development of pharmaceutically-produced transdermal cannabinoid therapies for rare and near-rare neuropsychiatric disorders, including Fragile X syndrome, autism spectrum disorder, 22q11.2 deletion syndrome, and a heterogeneous group of rare and ultra-rare epilepsies known as developmental and epileptic encephalopathies. The Company was incorporated on January 31, 2007 under the laws of the State of Delaware as AllTranz, Inc. and changed its name to Zynerba Pharmaceuticals, Inc. in August 2014.

The Company has incurred losses and negative cash flows from operations since inception and has an accumulated deficit of $150.8 million as of December 31, 2019. The Company anticipates incurring additional losses until such time, if ever, that it can generate significant revenue from its product candidates currently in development. The Company's primary source of liquidity has been the issuance of equity securities.

On August 30, 2019, the Company entered into a Controlled Equity Offering Sales AgreementSM (the “2019 Sales Agreement”) with Cantor Fitzgerald & Co., Canaccord Genuity, LLC, H.C. Wainwright & Co. LLC and Ladenburg Thalmann & Co. Inc., as sales agents (the “Agents”), pursuant to which the Company may sell, from time to time, up to $75.0 million of its common stock. From December 12, 2019 through March 4, 2020, the Company has sold and issued 353,171 shares of its common stock under the 2019 Sales Agreement in the open market at a weighted average selling price of $5.22 per share, resulting in gross proceeds of $1.8 million. Net proceeds after deducting commissions and offering expenses were $1.6 million. As of December 31, 2019, the Company sold and issued 13,381 shares of its common stock in the open market at a weighted-average selling price of $7.00, for gross and net proceeds of $0.1 million. From January 1, 2020 through March 4, 2020, the Company sold and issued 339,790 shares of its common stock in the open market at a weighted average selling price of $5.15 per share, for gross proceeds of $1.7 million and net proceeds, after deducting commissions and offering expenses, of $1.5 million.

In June 2017, the Company entered into an Open Market Sales Agreement (the “2017 Sales Agreement”) with Jefferies LLC, (“Jefferies”) pursuant to which the Company sold $50.0 million of its common stock. In the first quarter of 2019, the Company sold and issued 3,439,523 shares of common stock under the 2017 Sales Agreement with Jefferies in the open market at a weighted average selling price of $5.44 per share, resulting in gross proceeds of $18.7 million. Net proceeds received after deducting commissions and offering expenses were $18.1 million. In the second quarter of 2019, the Company sold and issued 2,082,031 shares of common stock under the 2017 Sales Agreement with Jefferies in the open market at a weighted average selling price of $13.50 per share, resulting in gross proceeds of $28.1 million. Net proceeds received after deducting commissions and offering expenses were $27.0 million. The last sale under the 2017 Sales Agreement was made on May 16, 2019. From June 2017 through May 16, 2019, the Company has cumulative gross proceeds of $50.0 million from shares sold in the open market under the 2017 Sales Agreement, which was terminated pursuant to its terms.

In July 2018, the Company completed a follow-on public offering, selling 4,062,500 shares of its common stock at an offering price of $8.00 per share, resulting in gross proceeds of $32.5 million. Net proceeds received after deducting underwriting discounts and commissions and offering expenses were $29.9 million.

In July 2019, the Australian government’s Department of Industry, Innovation and Science (“AusIndustry”) responded to an Advance Overseas Finding (“AOF”) application submitted by Zynerba that will allow certain research and development expenses incurred with respect to the Company’s product candidate Zygel™ outside of Australia to be eligible for the Australian research and development tax incentive program. As a result of this finding, the Company is eligible to receive a cash refund from the Australian Taxation Office for the qualifying research and development costs expended outside of Australia in 2018, 2019 and 2020. During the year ended December 31, 2019, the Company recorded $8.3 million as an Incentive and Tax Receivable and recorded a corresponding credit to research and development expense for amounts expected to be received through the AOF for the period January 1, 2018 through December 31, 2019. Although the AOF approval extends into 2020, management believes that substantially all qualifying amounts have been recorded as of December 31, 2019.

Management believes that current cash and cash equivalents and the proceeds anticipated from the AOF are sufficient to fund operations and capital requirements into the second half of 2021. Substantial additional financings will be needed by the Company to fund its operations, to complete clinical development of and to commercially develop its product candidates. There is no assurance that such financing will be available when needed or on acceptable terms.

The Company is subject to those risks associated with any clinical stage pharmaceutical company that has substantial expenditures for research and development. There can be no assurance that the Company's research and development projects will be successful, that products developed will obtain necessary regulatory approval, or that any approved product will be commercially viable. In addition, the Company operates in an environment of rapid technological change and is largely dependent on the services of its employees and consultants.
