CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Statements made in this Quarterly Report on Form 10-Q, or this Quarterly Report, that are not statements of historical or current facts, such as those under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements discuss our current expectations and projections relating to our financial condition, results of operations, plans, objectives, future performance and business. These statements may be preceded by, followed by or include the words “aim,” “anticipate,” “believe,” “estimate,” “expect,” “forecast,” “intend,” “outlook,” “plan,” “potential,” “project,” “projection,” “seek,” “may,” “could,” “would,” “will,” “should,” “can,” “can have,” “likely,” the negatives thereof and other words and terms of similar meaning.

Forward-looking statements are inherently subject to risks, uncertainties and assumptions; they are not guarantees of performance. You should not place undue reliance on these statements. We have based these forward-looking statements on our current expectations and projections about future events. Although we believe that our assumptions made in connection with the forward-looking statements are reasonable, we cannot assure you that the assumptions and expectations will prove to be correct.

You should understand that the following important factors could affect our future results and could cause those results or other outcomes to differ materially from those expressed or implied in our forward-looking statements:

● our expectations, projections and estimates regarding expenses, future revenue, capital requirements, incentive and other tax credit eligibility, collectability and timing and availability of and the need for additional financing;

● the results, cost and timing of our preclinical studies and clinical trials, including any delays to such clinical trials relating to enrollment or site initiation, as well as the number of required trials for regulatory approval and the criteria for success in such trials;

● our dependence on third parties in the conduct of our preclinical studies and clinical trials;

● legal and regulatory developments in the United States and foreign countries, including any actions or advice that may affect the design, initiation, timing, continuation, progress or outcome of clinical trials or result in the need for additional clinical trials;

● that the results of our preclinical studies and earlier clinical trials of our product candidates may not be predictive of future results and we may not have favorable results in our ongoing or planned clinical trials;

● the difficulties and expenses associated with obtaining and maintaining regulatory approval of our product candidates, and the indication and labeling under any such approval;

● our plans and ability to develop and commercialize our product candidates;

● the successful development of our commercialization capabilities, including sales and marketing capabilities, whether alone or with potential future collaborators;

● the size and growth of the potential markets for our product candidates, the rate and degree of market acceptance of our product candidates and our ability to serve those markets;

● the coverage and reimbursement status for our product candidates from third-party payors;

● the success of competing therapies and products that are or become available;

● our ability to limit our exposure under product liability lawsuits, shareholder class action lawsuits or other litigation;

● our ability to obtain and maintain intellectual property protection for our product candidates;

● legislative changes and recently proposed changes regarding the healthcare system, including changes and proposed changes to the Patient Protection and Affordable Care Act;

● our ability to obtain and maintain third-party manufacturing for our product candidates on commercially reasonable terms;

● delays, interruptions or failures in the manufacture and supply of our product candidates;

● the performance of third parties upon which we depend, including third-party contract research organizations, or CROs, contract manufacturing organizations, or CMOs, contractor laboratories and independent contractors;

● our ability to recruit or retain key scientific, commercial or management personnel or to retain our executive officers;

● our ability to maintain proper functionality and security of our internal computer and information systems and prevent or avoid cyberattacks, malicious intrusion, breakdown, destruction, loss of data privacy or other significant disruption;

3

● the extent to which health epidemics and other outbreaks of communicable diseases, including the ongoing COVID-19 pandemic, could disrupt our operations or materially and adversely affect our business and financial conditions;

● the extent to which inflation, global instability, including political instability, such as a deterioration in the relationship between the U.S. and China or the conflict between Russia and Ukraine, including any additional resulting sanctions, export controls or other restrictive actions that may be imposed by the U.S. and/or other countries against governmental or other entities in, for example, Russia, may disrupt our business operations and/or our financial condition; and

● the other risks, uncertainties and factors discussed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, or our 2021 Annual Report, and our Quarterly Report on Form 10-Q for the three months ended March 31, 2022, under the caption “Item 1A. Risk Factors”.

In light of these risks and uncertainties, expected results or other anticipated events or circumstances discussed in this Quarterly Report (including the exhibits hereto) might not occur. We undertake no obligation, and specifically decline any obligation, to publicly update or revise any forward-looking statements, even if experience or future developments make it clear that projected results expressed or implied in such statements will not be realized, except as may be required by law.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

(1) Nature of Business and Liquidity

Zynerba Pharmaceuticals, Inc., together with its subsidiary, Zynerba Pharmaceuticals Pty Ltd (collectively, “Zynerba,” the “Company,” or “we”), is a clinical stage specialty pharmaceutical company focused on the development of pharmaceutically-produced transdermal cannabinoid therapies for orphan neuropsychiatric disorders, including Fragile X syndrome (“FXS”) and chromosome 22q11.2 deletion syndrome (“22q”). We have been granted orphan drug designations from the United States Food and Drug Administration (“FDA”) and the European Commission for the use of cannabidiol for the treatment of FXS. We have also been granted orphan drug designation from the FDA for the treatment of 22q. In addition, we have received Fast Track designation from the FDA for treatment of behavioral symptoms associated with FXS. The Company has decided to prioritize its resources on FXS and 22q, both of which have no approved products. While the data from the Company’s autism spectrum disorder (“ASD”) clinical development program to date are compelling, given the difficult financial market, the Company has decided to defer the start of the Phase 3 development program in ASD that was previously planned for the second half of 2022.

The Company has incurred losses and negative cash flows from operations since inception and has an accumulated deficit of $257.8 million as of June 30, 2022. 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 May 11, 2021, the Company entered into a Controlled Equity Offering^SM Sales Agreement (the “2021 Sales Agreement”) with Cantor Fitzgerald & Co., Canaccord Genuity, LLC, H.C. Wainwright & Co. LLC and Ladenburg Thalmann & Co. Inc., as sales agents (collectively, the “2021 Sales Agents”), pursuant to which, under a prospectus filed by the Company in May 2022, the Company may sell, from time to time, up to $75.0 million of its common stock. In the first half of 2022, the Company sold and issued 1,345,952 shares of common stock under the 2021 Sales Agreement in the open market at a weighted average selling price of $1.97 per share, resulting in gross proceeds of $2.7 million. Net proceeds after deducting commissions and offering expenses were $2.4 million. From July 1, 2022 through August 8, 2022, the Company sold and issued 1,469,714 shares of its common stock in the open market at a weighted average selling price of $1.19 per share, for gross proceeds of $1.8 million and net proceeds, after deducting commissions and offering expenses, of $1.6 million.

In August 2019, the Company entered into a Controlled Equity Offering^SM Sales Agreement (the “2019 Sales Agreement”) with Cantor Fitzgerald & Co., Canaccord Genuity, LLC, H.C. Wainwright & Co. LLC and Ladenburg Thalmann & Co. Inc., as sales agents (collectively, the “2019 Sales Agents”), pursuant to which the Company sold $75.0 million of its common stock. In the first quarter of 2021, the Company sold and issued 10,244,326 shares of common stock under the 2019 Sales Agreement in the open market at a weighted average selling price of $4.22 per share, resulting in gross proceeds of $43.2 million. Net proceeds after deducting commissions and offering expenses were $42.2 million. As of February 9, 2021, the Company had utilized the entire $75.0 million under the 2019 Sales Agreement.

Management believes that the Company’s cash and cash equivalents as of June 30, 2022 are sufficient to fund operations and capital requirements through the end of 2023 or early 2024, after the expected availability of top line results from its confirmatory pivotal Phase 3 RECONNECT trial of Zygel in patients with FXS. Substantial additional financings will be needed by the Company to fund its operations, and to complete clinical development of and to commercially develop its product candidates. The Company’s ability to raise sufficient additional financing depends on many factors beyond its control, including the current and ongoing volatility in the capital markets as a result of, among other factors, the COVID-19 pandemic and geopolitical tensions or the outbreak of hostilities or war. 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.

(2) Summary of Significant Accounting Policies

a. Basis of Presentation

The accompanying unaudited interim consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. The interim unaudited consolidated financial statements have been prepared on the same basis as the consolidated financial statements as of and for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Annual Report”), filed with the Securities and Exchange Commission (the “SEC”). In the opinion of management, the accompanying consolidated financial statements of the Company include all normal and recurring adjustments (which consist primarily of accruals, estimates and assumptions that impact the consolidated financial statements) considered necessary to present fairly the Company's financial position as of June 30, 2022 its results of operations for the three and six months ended June 30, 2022 and 2021 and cash flows for the six months ended June 30, 2022 and 2021. Operating results for any interim period are not necessarily indicative of results for any future interim period or for the entire year. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the 2021 Annual Report.

b. Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of expenses during the reporting period. Actual results could differ from such estimates.

c. Incentive and Tax Receivables

The Company’s subsidiary, Zynerba Pharmaceuticals Pty Ltd (the “Subsidiary”), is incorporated in Australia. The Subsidiary is eligible to participate in an Australian research and development tax incentive program. As part of this program, the Subsidiary is eligible to receive a cash refund from the Australian Taxation Office (“ATO”) for a percentage of the research and development costs expended by the Subsidiary in Australia. The cash refund is available to eligible companies with an annual aggregate revenue of less than $20.0 million (Australian) during the reimbursable period. The Company estimates the amount of cash refund it expects to receive related to the Australian research and development tax incentive program and records the incentives when it is probable (1) the Company will comply with relevant conditions of the program and (2) the incentive will be received. The Company evaluates its eligibility under tax incentive programs as of each balance sheet date based on the most current and relevant data available. If the Company is deemed to be ineligible or unable to receive the Australian research and development tax credit, or the Australian government significantly reduces or eliminates the tax credit, the actual cash refund the Company receives may materially differ from its estimates.

In December 2018, the Company submitted an Advance Overseas Finding (“AOF”) application to a division of the Australian Government’s Department of Industry, Innovation and Science (“AusIndustry”), for a portion of the Company’s research and development activities incurred outside of Australia, which was approved by AusIndustry in July 2019. 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. In June 2020, the ATO informed the Company that it may not qualify for the AOF program based on their interpretation of certain eligibility requirements and, during the three months ended June 30, 2020, the Company determined it was no longer probable that the AOF claim would be received and the Company recorded a full reserve against the AOF receivable.

During the three months ended March 31, 2022, the Company concluded its conversations with the ATO on these matters and made the decision to no longer pursue the AOF claim, resulting in the write off of both the AOF receivable and the corresponding reserve during the period. During the three months ended March 31, 2022, the Company received a payment of $8.0 million from the ATO for the non-AOF research and development incentive for the years ended December 31, 2018, 2019 and 2020.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The Subsidiary incurs Goods and Services Tax (“GST”) on services provided by Australian vendors. As an Australian entity, the Subsidiary is entitled to a refund of the GST paid. The Company’s estimate of the amount of cash refund it expects to receive related to GST incurred is included in “Incentive and tax receivables” in the accompanying consolidated balance sheets. As of June 30, 2022, incentive and tax receivables included $0.3 million for refundable GST on expenses incurred with Australian vendors during the three months ended June 30, 2022.

Current incentive and tax receivables consisted of the following as of June 30, 2022 and December 31, 2021:

As of June 30, 2022, the Company’s estimate of the amount of cash refund it expects to receive for 2021 eligible spending as part of this incentive program was $1.2 million and was recorded as a current asset. The Company’s estimate of the amount of cash refund it expects to receive for 2022 eligible spending through June 30, 2022 was $0.6 million and was recorded as a non-current asset.

d. Research and Development

Research and development costs are expensed as incurred and are primarily comprised of external research and development expenses incurred under arrangements with third parties, such as contract research organizations, contract manufacturing organizations, consultants and employee-related expenses including salaries and benefits. At the end of each reporting period, the Company compares the payments made to each service provider to the estimated progress towards completion of the related project. Factors that the Company considers in preparing these estimates include the number of patients enrolled in studies, milestones achieved and other criteria related to the efforts of its vendors. These estimates will be subject to change as additional information becomes available. Depending on the timing of payments to vendors and estimated services provided, the Company will record net prepaid or accrued expenses related to these costs. Research and development expenses are recorded net of expected refunds of eligible research and development costs paid pursuant to the Australian research and development tax incentive program and GST incurred on services provided by Australian vendors.

The following table summarizes research and development expenses for the six months ended June 30, 2022 and 2021:

	Six months ended June 30,
	2022		2021
Research and development expenses - before R&D incentive	$	11,176,773	$	10,622,323
Research and development incentive		(583,851)		(561,365)
Total research and development expenses	$	10,592,922	$	10,060,958

e. Net Loss Per Share

Basic net loss per share is determined using the weighted average number of shares of common stock outstanding during each period. Diluted net income per share includes the effect, if any, from the potential exercise or conversion of securities, such as restricted stock and stock options, which would result in the issuance of incremental shares of

11

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

common stock. Basic and dilutive computations of net loss per share are the same in periods in which a net loss exists as the dilutive effects of restricted stock and stock options would be anti-dilutive.

The following potentially dilutive securities outstanding as of June 30, 2022 and 2021 have been excluded from the computation of diluted weighted average shares outstanding, as their effects on net loss per share for the periods presented would be anti-dilutive:

	June 30,
	2022	2021
Stock options	6,276,016	5,225,538
Unvested restricted stock	2,307,476	1,185,822
	8,583,492	6,411,360

f. Recent Accounting Pronouncements

The Company does not expect any recently issued accounting pronouncements to have a significant impact on its future results of operations, financial position or cash flow.

(3) Fair Value Measurements

The Company measures certain assets and liabilities at fair value in accordance with Accounting Standards

Codification (“ASC 820”), Fair Value Measurements and Disclosures. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability (the exit price) in an orderly transaction between market participants at the measurement date. The guidance in ASC 820 outlines a valuation framework and creates a fair value hierarchy that serves to increase the consistency and comparability of fair value measurements and the related disclosures. In determining fair value, the Company maximizes the use of quoted prices and observable inputs. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from independent sources. The fair value hierarchy is broken down into three levels based on the source of inputs as follows:

Level 1 — Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 — Valuations based on observable inputs and quoted prices in active markets for similar assets and liabilities.

Level 3 — Valuations based on unobservable inputs and models that are supported by little or no market activity.

In accordance with the fair value hierarchy described above, the following table sets forth the Company's financial assets measured at fair value on a recurring basis as of June 30, 2022 and December 31, 2021:

			Fair Value Measurement

On May 11, 2021, the Company entered into the 2021 Sales Agreement with the 2021 Sales Agents, pursuant to which, under a prospectus filed by the Company in May 2022, the Company may sell, from time to time, up to $75.0 million of its common stock. In the first half of 2022, the Company sold and issued 1,345,952 shares of common stock under the 2021 Sales Agreement in the open market at a weighted average selling price of $1.97 per share, resulting in gross proceeds of $2.7 million. Net proceeds after deducting commissions and offering expenses were $2.4 million. From July 1, 2022 through August 8, 2022, the Company sold and issued 1,469,714 shares of its common stock in the open market at a weighted average selling price of $1.19 per share, for gross proceeds of $1.8 million and net proceeds, after deducting commissions and offering expenses, of $1.6 million.

In August 2019, the Company entered into the 2019 Sales Agreement with the 2019 Sales Agents pursuant to which the Company sold $75.0 million of its common stock. In the first quarter of 2021, the Company sold and issued 10,244,326

13

ZYNERBA PHARMACEUTICALS, INC.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

shares of common stock under the 2019 Sales Agreement in the open market at a weighted average selling price of $4.22 per share, resulting in gross proceeds of $43.2 million. Net proceeds after deducting commissions and offering expenses were $42.2 million. As of February 9, 2021, the Company had utilized the entire $75.0 million under the 2019 Sales Agreement.

(8) Stock-Based Compensation

The Company maintains the Amended and Restated 2014 Omnibus Incentive Compensation Plan, as amended (the “2014 Plan”), which allows for the granting of incentive stock options, nonqualified stock options, stock appreciation rights, stock awards, stock units, performance units and other stock-based awards to employees, officers, non-employee directors, consultants, and advisors. In addition, the 2014 Plan provides selected executive employees with the opportunity to receive bonus awards that are considered qualified performance-based compensation. The 2014 Plan is subject to automatic annual increases in the number of shares authorized for issuance under the 2014 Plan on the first trading day of January each year equal to the lesser of 1.5 million shares or 10% of the number of shares of common stock outstanding on the last trading day of December of the preceding year. As of January 1, 2022, the number of shares of common stock that may be issued under the 2014 Plan was automatically increased by 1.5 million shares, increasing the total number of shares of common stock available for issuance under the 2014 Plan to 10,804,869 shares. As of June 30, 2022, 1,442,876 shares were available for future issuance under the 2014 Plan.

Options issued under the 2014 Plan have a contractual life of 10 years and may be exercisable in cash or as otherwise determined by the board of directors. The Company has granted options to employees and non-employee directors. Stock options granted to employees primarily vest 25% upon the first anniversary of the grant date and the balance of unvested options vests in quarterly installments over the remaining three years. Stock options granted annually to non-employee directors vest on the earlier of the one-year anniversary of the grant date, or the date of the Company’s next annual stockholders’ meeting that occurs after the grant date. The Company’s non-employee director compensation policy enables directors to receive stock options in lieu of quarterly cash payments. Any option granted to the directors in lieu of cash compensation vests in full on the grant date. The Company records forfeitures as they occur.

Stock-based compensation expense for performance-based grants are recorded when management estimates that the vesting of these shares is probable based on the status of the Company’s research and development programs and other relevant factors, which were established by the Company’s board of directors. The Company’s board of directors determines if the performance conditions have been met.

During the six months ended June 30, 2021, the Company granted 506,911 time-based restricted stock awards to employees with two-year cliff vesting of which 469,911 restricted stock awards remained outstanding as of June 30, 2022. In addition, during the six months ended June 30, 2021, the Company granted 506,911 performance-based restricted stock awards to employees of which 469,911 restricted stock awards remained outstanding as of June 30, 2022. The performance-based conditions for these performance-based grants were deemed probable of achievement during the six months ended June 30, 2021 and, as of June 30, 2022, the Company has recorded $1.6 million in stock-based compensation expense related to these grants. As of June 30, 2022, there was $0.1 million of unrecognized stock-based compensation expense related to these performance-based awards, which will be expensed over the estimated service period related to each performance condition.

During the six months ended June 30, 2022, the Company granted 841,654 time-based restricted stock awards to employees, non-employee directors and consultants of which 824,654 restricted stock awards remained outstanding as of June 30, 2022. In addition, during the six months ended June 30, 2022, the Company granted 556,500 performance-based restricted stock awards to employees of which 548,000 restricted stock awards remained outstanding as of June 30, 2022. As of June 30, 2022, none of the performance-based metrics were deemed probable of achievement.

(9) Operating Lease Obligations

The Company adopted Accounting Standards Update No. 2016-02, Leases (Topic 842), Accounting Standards Codification 842 prospectively using the modified-retrospective method and elected the package of transition practical expedients that does not require reassessment of: (1) whether any existing or expired contracts are or contain leases, (2) lease classification and (3) initial direct costs. In addition, the Company has elected other available practical expedients to not separate lease and nonlease components, which consist principally of common area maintenance charges, and to exclude leases with an initial term of 12 months or less.

The Company leases its headquarters where it occupies 10,877 square feet of office space. On March 1, 2021, the Company extended its lease for three additional years until May 31, 2024. The Company’s lease contains variable lease costs that do not depend on a rate or index and consist primarily of common area maintenance, taxes, and insurance charges. As the implicit rate was not readily determinable for the Company’s lease, the Company used an estimated incremental borrowing rate, or discount rate, to determine the initial present value of the lease payments. The discount rate for the lease was calculated using a synthetic credit rating model.

As of March 1, 2021, the effective date of the lease modification, the Company remeasured the lease liability for the remaining portion of the lease and adjusted the lease liability to $755,085 and right-of-use assets to $752,391, which was recorded net of a deferred rent liability of $2,694. As of June 30, 2022, the Company’s right-of-use asset, net of amortization, was $451,800.

Other operating lease information as of June 30, 2022:

Weighted-average remaining lease term - operating leases	1.9	years
Weighted-average discount rate - operating leases	2.76	%

Note 10 – Subsequent Events

Common Stock Purchase Agreement – Lincoln Park Equity Line of Credit

On July 21, 2022 (the “Effective Date”), the Company entered into a Purchase Agreement (the “Purchase Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”), pursuant to which the Company has the right, but not the

16

ZYNERBA PHARMACEUTICALS, INC.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

obligation, to sell to Lincoln Park, and Lincoln Park is obligated to purchase, up to $20.0 million of the Company’s common stock. Such sales of common stock by the Company, if any, will be subject to certain limitations, and may occur from time to time, at the Company’s sole discretion, over the 36-month period commencing on the Effective Date. Pursuant to the terms of the Purchase Agreement, the Company issued 347,222 shares of its common stock to Lincoln Park as consideration for its commitment to purchase shares of the Company’s common stock under the Purchase Agreement.

Concurrently with entering into the Purchase Agreement, the Company also entered into a registration rights agreement with Lincoln Park (the “Registration Rights Agreement”) pursuant to which the Company agreed to register the sale of the shares of the Company’s common stock that have been and may be issued to Lincoln Park under the Purchase Agreement pursuant to the Company’s existing shelf registration statement on Form S-3 (File No. 333-264966) or a new registration statement.

The number of shares the Company may sell to Lincoln Park on any single business day in a regular purchase is 150,000 shares, but that amount may be increased up to 300,000 shares, depending upon the closing price of the Company’s common stock on the Nasdaq Global Market (“Nasdaq”) and subject to a maximum limit of $2.0 million per regular purchase. The purchase price per share for each such regular purchase will be based on prevailing market prices of the Company’s common stock immediately preceding the time of sale as computed under the Purchase Agreement. In addition to regular purchases, the Company may also direct Lincoln Park to purchase other amounts as accelerated purchases or as additional accelerated purchases.

Under applicable rules of Nasdaq, in no event may the Company issue or sell to Lincoln Park under the Purchase Agreement shares of its common stock, including the Commitment Shares, in excess of 8,898,867 shares, which is equal to 19.99% of the shares of the Company’s common stock outstanding immediately prior to the execution of the Purchase Agreement (the “Exchange Cap”) unless (i) the Company obtains stockholder approval to issue shares of its common stock in excess of the Exchange Cap or (ii) the average price of all shares of the Company’s common stock issued to Lincoln Park under the Purchase Agreement equals or exceeds $1.13 per share (which represents the average of the official closing prices of the Company’s common stock on Nasdaq for the five (5) trading days immediately preceding the signing of the Purchase Agreement), such that the transactions contemplated by the Purchase Agreement are exempt from the Exchange Cap limitation under applicable Nasdaq rules. In any event, the Purchase Agreement specifically provides that the Company may not issue or sell any shares of its common stock under the Purchase Agreement if such issuance or sale would breach any applicable rules or regulations of the Nasdaq.

Actual sales of shares of common stock to Lincoln Park under the Purchase Agreement will depend on a variety of factors to be determined by the Company from time to time, including, among others, market conditions, the trading price of the Company’s common stock and determinations by the Company as to the appropriate sources of funding for the Company and its operations. The Company may not sell shares of its common stock to Lincoln Park under the Purchase Agreement if doing so would result in Lincoln Park beneficially owning more than 9.99% of the Company’s common stock.

The net proceeds, if any, under the Purchase Agreement will depend on the frequency and prices at which the Company sells shares of its common stock to Lincoln Park. The Company intends to use any net proceeds from the sale of its common stock to Lincoln Park for working capital and general corporate purposes, including research and development expenses and capital expenditures. The Company also agreed to reimburse Lincoln Park for a limited portion of the legal fees it incurred in connection with the Purchase Agreement.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited interim consolidated financial statements and related notes appearing elsewhere in this Quarterly Report and the audited consolidated financial statements and notes thereto for the year ended December 31, 2021 and the related Management’s Discussion and Analysis of Financial Condition and Results of Operations, both of which are contained in our 2021 Annual Report. The following discussion contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results and the timing of certain events could differ materially from those anticipated in these forward-looking statements as a result of many factors. We discuss factors that we believe could cause or contribute to these differences below and elsewhere in this Quarterly Report, including those set forth under “Cautionary Note Regarding Forward-looking Statements” and “Risk Factors” in this Quarterly Report and our 2021 Annual Report.

Overview

Company Overview

We are the leader in pharmaceutically-produced transdermal cannabinoid therapies for orphan neuropsychiatric disorders. We are committed to improving the lives of patients and their families living with severe, chronic health conditions, including Fragile X syndrome, or FXS, and chromosome 22q11.2 deletion syndrome, or 22q.

Cannabinoids are a class of compounds derived from Cannabis plants. The two primary cannabinoids contained in Cannabis are cannabidiol and tetrahydrocannabinol, or THC. Clinical and preclinical data suggest that cannabidiol may have positive effects on treating behavioral symptoms of FXS and 22q.

We are currently developing Zygel, the first and only pharmaceutically-produced cannabidiol formulated as a permeation-enhanced gel for transdermal delivery and manufactured without the presence of THC, which is patent protected through 2030. Five additional patents expiring in 2038 are directed to methods of use relating to Zygel, including methods of treating FXS and ASD.

In preclinical animal studies, Zygel’s permeation enhancer increased delivery of cannabidiol through the layers of the skin and into the circulatory system. These preclinical studies suggest increased bioavailability, consistent plasma levels and the avoidance of first-pass liver metabolism of cannabidiol when delivered transdermally. In addition, an in vitro study published in Cannabis and Cannabinoid Research in April 2016 demonstrated that cannabidiol is degraded to THC (the major psychoactive cannabinoid in Cannabis) in an acidic environment such as the stomach. As a result, we believe such degradation may lead to increased psychoactive effects if cannabidiol is delivered orally. These effects may be avoided with the transdermal delivery of Zygel, which maintains cannabidiol in a neutral pH.

Zygel is being developed as a clear gel and is targeting treatment of behavioral symptoms of FXS and 22q. We have received orphan drug designations from the United States Food and Drug Administration, or FDA, for cannabidiol, the active ingredient in Zygel, for the treatment of FXS and 22q. During the first quarter of 2022, we received orphan drug designation from the European Commission for cannabidiol, the active ingredient in Zygel, for the treatment of FXS. In May 2019, we received Fast Track designation from the FDA for treatment of behavioral symptoms associated with FXS. The FDA’s Fast Track program is designed to facilitate the development of drugs intended to treat serious conditions and fill unmet medical needs and can lead to expedited review by the FDA in order to get new important drugs to the patient earlier.

18

Clinical Development Programs

Our clinical programs for Zygel include ongoing and planned clinical trials evaluating Zygel in the treatment of behavioral symptoms of FXS, 22q and ASD.

The Zygel safety database across all clinical studies conducted by us includes data from more than 900 volunteers and patients. Across these clinical studies, Zygel has been well-tolerated with a safety profile that has been consistent across our Phase 2 and Phase 3 clinical trials.

FXS

CONNECT-FX Trial

In June 2020, we announced results of our CONNECT-FX clinical trial, a multi-national randomized, double-blind, placebo-controlled, 14-week study designed to assess the efficacy and safety of Zygel in children and adolescents ages three through 17 years who have full mutation of the FMR1 gene. While Zygel did not achieve statistical significance versus placebo in the primary endpoint of improvement in the Social Avoidance subscale of the Aberrant Behavior Checklist – Community FXS, or ABC-C_FXS, a pre-planned ad hoc analysis of the most severely impacted patients in the trial, as defined by patients having at least 90% methylation (“highly methylated”) of the impacted FMR1 gene, demonstrated that those patients receiving Zygel achieved statistical significance in the primary endpoint of improvement at 12 weeks of treatment in the Social Avoidance subscale of the ABC-C_FXS compared to placebo. We performed a subsequent analysis of the CONNECT-FX population within those patients having 100% or complete methylation of the impacted FMR1 gene, which demonstrated that these patients having complete methylation and receiving Zygel similarly achieved statistical significance in the primary endpoint of improvement at 12 weeks of treatment in the Social Avoidance subscale of the ABC-C_FXS compared to placebo.

RECONNECT Trial

In September 2021, we announced that we had initiated our RECONNECT (A Randomized, Double-Blind, Placebo-Controlled, Multiple-Center, Efficacy and Safety Study of ZYN002 Administered as a Transdermal Gel to Children and Adolescents with Fragile X Syndrome) trial, a pivotal, multi-national, confirmatory Phase 3 trial of Zygel in patients with FXS. The trial is designed to confirm the positive results observed in a population of responders in our CONNECT-FX trial.

RECONNECT is an 18-week trial that is expected to enroll approximately 200 children and adolescents, aged three through 17 years, at approximately 25 clinical sites in the United States, Australia, the United Kingdom and Ireland. Approximately 160 of the patients enrolled will have complete (100%) methylation of their FMR1 gene and

19

approximately 40 patients will have partial methylation of their FMR1 gene. Patients will be randomized 1:1 to either Zygel or placebo. Randomization will be stratified by gender, methylation status and weight.

The primary endpoint for the trial will be the change from baseline to the end of the treatment period in the ABC-C_FXS Social Avoidance subscale in patients who have complete methylation of their FMR1 gene. The ABC-C_FXS Social Avoidance subscale is the same primary endpoint used in the CONNECT-FX trial.

Key secondary efficacy endpoints include: (i) the change from baseline to the end of the treatment period in the ABC-C_FXS Irritability subscale in patients who have complete methylation of their FMR1 gene; (ii) the percent of patients with any improvement on the Caregiver Global Impression of Change, or CaGI-C, at the end of the treatment period for Social Interactions among patients with complete methylation of the FMR1 gene; (iii) the percent of patients rated as improved on the Clinical Global Impression- Improvement, or CGI-I, scale among patients with complete methylation (100%) of the FMR1 gene; and (iv) the change from baseline to the end of the treatment period in the ABC-C_FXS Social Avoidance subscale among all randomized patients (complete and partial methylation of the FMR1 gene).

Top-line results for the RECONNECT trial are expected in the second half of 2023. All patients who complete dosing in the RECONNECT trial will be eligible to enroll in our ongoing open-label extension trial.

22q

Phase 2 INSPIRE Trial

In June 2022, we announced top line results from our open-label Phase 2 INSPIRE clinical trial, a 14-week, open-label clinical trial designed to assess the safety, tolerability and efficacy of Zygel for treatment of behavioral symptoms of 22q. The Phase 2 trial was designed for signal detection by assessing the safety, tolerability and efficacy of Zygel (also known as ZYN002) for the treatment of behavioral symptoms of chromosome 22q11.2 deletion syndrome in children and adolescents. Zygel was administered to patients with 22q as add-on therapy to their standard of care and utilized a variety of efficacy assessments. Key findings from the trial include:

● The total score and all five subscales of the Anxiety, Depression and Mood Scale (ADAMS) showed statistically significant improvements at 14 weeks of treatment compared to baseline;

● All five subscales of the Aberrant Behavior Checklist – Community, or ABC-C, showed statistically significant improvements at 14 weeks of treatment compared to baseline;

● The Pediatric Anxiety Rating Scale (PARS – R) showed statistically significant improvements at 14 weeks of treatment compared to baseline; and

● The majority of patients showed clinically meaningful improvements at week 14 as demonstrated by the CGI-I. Seventy-five percent of patients were rated by the clinicians as “improved,” “much improved” or “very much improved” with nearly two-thirds (62.5%) of the patients being “much improved” or “very much improved.”

Zygel was shown to be well tolerated, and the safety profile was consistent with previously released data from other Zygel clinical trials. Three patients reported treatment related adverse events which were all mild application site adverse events. One patient discontinued treatment due to adverse events not related to Zygel.

Based on the positive Phase 2 data, the Company will request a meeting with the FDA to discuss the data and the regulatory path forward.

ASD

Phase 2 BRIGHT Trial

In May 2020, we reported positive top-line results of our Phase 2 BRIGHT clinical trial, a 14-week, open-label clinical trial designed to assess the safety, tolerability and efficacy of Zygel for the treatment of pediatric and adolescent patients with ASD. Patients treated with Zygel demonstrated statistically significant improvement at week 14 compared to baseline for each ABC-C subscale (Irritability, Inappropriate Speech, Stereotypy, Social Withdrawal and Hyperactivity).

20

The results of the other efficacy assessments were consistent with the results demonstrated in the ABC-C. In September 2021, we reported additional safety and efficacy data from our BRIGHT trial for the 18 patients that continued from week 14 through a longer term, 38-week treatment period, which we refer to as Period 2. In the 18 patients who completed treatment through the 38-week treatment period, statistically significant improvements compared to baseline were sustained in all efficacy measures.

While the data from the Company’s ASD clinical development program to date are compelling, given the difficult financial market, the Company has decided to prioritize its resources on FXS and 22q and defer the start of the Phase 3 development program in ASD that was previously planned for the second half of 2022.

Impact of COVID-19

We continue to closely monitor the status of the COVID-19 pandemic, including its potential impact on our clinical development plans, patient recruitment and overall clinical trial timelines going forward. In response to the impact of COVID-19, for our current clinical development programs, we implemented multiple measures consistent with the FDA’s guidance on the conduct of clinical trials of medical products during the COVID-19 pandemic, including remote site monitoring and patient visits using telemedicine where needed and appropriate, direct-to-patient drug shipments and local study-related clinical laboratory collection.

Operations

We have never been profitable and have incurred net losses since inception. Our net losses were $18.3 million and $17.9 million for the six months ended June 30, 2022 and 2021, respectively. As of June 30, 2022, our accumulated deficit was $257.8 million. We expect to incur losses for the foreseeable future, and we expect these losses to increase as we continue our development of, and seek regulatory approvals for, our product candidates. Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when, or if, we will be able to achieve or maintain profitability.

Financial Operations Overview

The following discussion sets forth certain components of our consolidated statements of operations as well as factors that impact those items.

Research and Development Expenses 

Our research and development expenses relating to our product candidates consisted of the following:

● expenses associated with preclinical development and clinical trials;

● personnel-related expenses, such as salaries, benefits, travel and other related expenses, including stock-based compensation;

● payments to third-party CROs, CMOs, contractor laboratories and independent contractors; and

● depreciation, maintenance and other facility-related expenses.

We expense all research and development costs as incurred. Clinical development expenses for our product candidates are a significant component of our current research and development expenses. Generally, expenses associated with clinical trials will increase as our clinical trials progress. Product candidates in later stage clinical development generally have higher research and development expenses than those in earlier stages of development, primarily due to increased size and duration of the clinical trials. We track and record information regarding external research and development expenses for each grant, study or trial that we conduct. We use third-party CROs, CMOs, contractor laboratories and independent contractors in preclinical studies and clinical trials. We recognize the expenses associated with third parties performing these services for us in our preclinical studies and clinical trials based on the percentage of each study completed at the end of each reporting period.

21

Our Australian subsidiary, Zynerba Pharmaceuticals Pty Ltd, or the Subsidiary, is incorporated in Australia and is eligible to participate in an Australian research and development tax incentive program. As part of this program, the Subsidiary is eligible to receive a cash refund from the Australian Taxation Office, or the ATO, for a percentage of the research and development costs expended by the Subsidiary in Australia. The cash refund is available to eligible companies with an annual aggregate revenue of less than $20.0 million (Australian dollars) during the reimbursable period. We estimate the amount of cash refund we expect to receive related to the Australian research and development tax incentive program and record the incentives when it is probable (1) we will comply with relevant conditions of the program and (2) the incentive will be received. We evaluate the Subsidiary’s eligibility under tax incentive programs as of each balance sheet date based on the most current and relevant data available. If the Subsidiary is deemed to be ineligible or unable to receive the Australian research and development tax credit, or the Australian government significantly reduces or eliminates the tax credit, the actual cash refund we receive may materially differ from our estimates.

The following table summarizes research and development expenses for the six months ended June 30, 2022 and 2021:

	Six months ended June 30,
	2022		2021
Research and development expenses - before R&D incentive	$	11,176,773	$	10,622,323
Research and development incentive		(583,851)		(561,365)
Total research and development expenses	$	10,592,922	$	10,060,958

We expect research and development expenses to increase for the year ending December 31, 2022 as compared to 2021, as we continue to conduct our RECONNECT clinical trial for FXS. These expenditures are subject to numerous uncertainties regarding timing and cost to completion. Completion of our preclinical development and clinical trials may take several years or more and the length of time generally varies according to the type, complexity, novelty and intended use of a product candidate. The cost of clinical trials may vary significantly over the life of a project as a result of differences arising during clinical development, including, among others:

● the number of sites included in the clinical trials;

● the length of time required to enroll suitable patients;

● the size of patient populations participating in the clinical trials;

● the duration of patient follow-ups;

● the development stage of the product candidates; and

● the efficacy and safety profile of the product candidates.

Due to the early stages of our research and development, we are unable to determine the duration or completion costs of our development of our product candidates. As a result of the difficulties of forecasting research and development costs of our product candidates as well as the other uncertainties discussed above, we are unable to determine when and to what extent we will generate revenue from the commercialization and sale of an approved product candidate.

General and Administrative Expenses 

General and administrative expenses consist primarily of salaries, benefits and other related costs, including stock-based compensation, for personnel serving in our executive, finance, legal, human resource, investor relations and commercial functions. Our general and administrative expenses also include facility and related costs not included in research and development expenses, professional fees for legal services, including patent-related expenses, litigation settlement expenses, consulting, tax and accounting services, insurance, market research and general corporate expenses. We expect that our general and administrative expenses will increase for the next several years as we increase our headcount with the continued development and potential commercialization of our product candidates.

22

Interest Income

Interest income primarily consists of interest earned on balances maintained in our money market bank account. 

Foreign Exchange Loss

Foreign exchange loss relates to the effect of exchange rates on transactions incurred by the Subsidiary.

Critical Accounting Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reported period. In accordance with GAAP, we base our estimates on historical experience, known trends and events and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We define our critical accounting policies as those that require us to make subjective estimates and judgments about matters that are uncertain and are likely to have a material impact on our financial condition and results of operations as well as the specific manner in which we apply those principles. Critical accounting estimates and the accounting policies critical to the process of making significant judgments and estimates in the preparation of our consolidated financial statements are discussed in our 2021 Annual Report under Part II, Item 7, “Critical Accounting Policies and Use of Estimates.” During the six months ended June 30, 2022, there have been no material changes to the critical accounting estimates or critical accounting policies discussed in our 2021 Annual Report.

Results of Operations

Comparison of the Three Months Ended June 30, 2022 and 2021

Research and Development Expenses

Research and development expenses for the three months ended June 30, 2022 and 2021 were $5.4 million and $5.5 million, respectively. Decreases in clinical and stock-based compensation expenses were offset by increases in manufacturing costs associated with our Zygel program.

General and Administrative Expenses

General and administrative expenses decreased by $0.7 million, or 15%, to $3.7 million for the three months ended June 30, 2022 from $4.4 million for the three months ended June 30, 2021. The decrease was primarily related to lower stock-based compensation expenses and a decrease in proxy solicitation costs related to our annual meeting partially offset by increased directors’ and officers’ liability insurance costs.

Other Income (Expense)

During the three months ended June 30, 2022 and 2021, we recognized $0.1 million and $5,943, respectively, in interest income. The increase in interest income was due to higher average interest rates earned on our investments. During the three months ended June 30, 2022 and 2021, we recognized foreign currency losses of $0.8 million and $0.1 million, respectively. Foreign currency gains and losses are due primarily to the remeasurement of the Subsidiary’s assets and liabilities, which are denominated in the local currency to the Subsidiary’s functional currency, which is the U.S. dollar.

23

Comparison of the Six Months Ended June 30, 2022 and 2021

Research and Development Expenses

Research and development expenses increased by $0.5 million, or 5%, to $10.6 million for the six months ended June 30, 2022 from $10.1 million for the six months ended June 30, 2021. The increase was primarily related to increases in manufacturing costs associated with our Zygel program and increased employee-related costs partially offset by reductions in clinical and stock-based compensation expenses.

General and Administrative Expenses

General and administrative expenses decreased by $0.2 million, or 2%, to $7.5 million for the six months ended June 30, 2022 from $7.7 million for the six months ended June 30, 2021. The decrease was primarily related to lower stock-based compensation expenses and a decrease in proxy solicitation costs related to our annual meeting partially offset by higher employee-related costs, including recruiting fees and increased directors’ and officers’ liability insurance costs.

Other Income (Expense)

During the six months ended June 30, 2022 and 2021, we recognized $0.2 million and $11,576 respectively, in interest income. The increase in interest income was related to interest income received from the ATO for the payment of prior year’s non-AOF research and development incentives and higher average interest rates earned on our investments. During the six months ended June 30, 2022 and 2021, we recognized foreign currency losses of $0.5 million and $0.2 million, respectively. Foreign currency gains and losses are due primarily to the remeasurement of the Subsidiary’s assets and liabilities, which are denominated in the local currency to the Subsidiary’s functional currency, which is the U.S. dollar.

Liquidity and Capital Resources

Since our inception in 2007, we have devoted most of our cash resources to research and development and general and administrative activities. We have financed our operations primarily with the proceeds from the issuance and sale of equity securities (most notably our initial public offering, our follow-on public offerings and sales under our “at-the-market” offerings), convertible promissory notes, state and federal grants and research services.

To date, we have not generated any revenue from the sale of products, and we do not anticipate generating any revenue from the sales of products for the foreseeable future. We have incurred losses and generated negative cash flows from operations since inception. As of June 30, 2022, our principal sources of liquidity were our cash and cash equivalents of $62.5 million. Our working capital was $56.1 million as of June 30, 2022.

Management believes that cash and cash equivalents as of June 30, 2022 are sufficient to fund operations and capital requirements through the end of 2023 or early 2024, after the expected availability of top line results from its confirmatory pivotal Phase 3 RECONNECT trial of Zygel in patients with FXS. The economic effects of the COVID-19 pandemic remain fluid and management will continue to closely monitor the situation to ensure our cash and cash equivalents will help us manage the impact of the COVID-19 pandemic on our business and related liquidity needs. Substantial additional financings will be needed to fund our operations and to complete clinical development of and to commercially develop our product candidates. There can be no assurance that such financing will be available when needed or on acceptable terms. Our ability to access the capital markets or otherwise raise such capital may be adversely impacted by global economic conditions and the disruptions to, and volatility in, financial markets in the United States and worldwide resulting from, among other factors, inflation, the ongoing COVID-19 pandemic and geopolitical tensions or the outbreak of hostilities or war.

Equity Financings

On May 11, 2021, we entered into a Controlled Equity Offering^SM Sales Agreement, or the 2021 Sales Agreement, with Cantor Fitzgerald & Co., Canaccord Genuity, LLC, H.C. Wainwright & Co. LLC and Ladenburg Thalmann & Co. Inc., as sales agents, pursuant to which, under a prospectus filed in May 2022, we may sell, from time to time, up to $75.0 million of our common stock. In the first half of 2022, we sold and issued 1,345,952 shares of common stock under the 2021 Sales Agreement in the open market at a weighted average selling price of $1.97 per share, resulting in gross

24

proceeds of $2.7 million. Net proceeds after deducting commissions and offering expenses were $2.4 million. From July 1, 2022 through August 8, 2022, we sold and issued 1,469,714 shares of its common stock in the open market at a weighted average selling price of $1.19 per share, for gross proceeds of $1.8 million and net proceeds, after deducting commissions and offering expenses, of $1.6 million.

Debt

We had no debt outstanding as of June 30, 2022 or December 31, 2021.

Future Capital Requirements

During the six months ended June 30, 2022, net cash used in operating activities was $7.7 million, and our accumulated deficit as of June 30, 2022 was $257.8 million. Our expectations regarding future cash requirements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures or investments that we may make in the future. To the extent that we enter into any of those types of transactions, we may need to raise substantial additional capital.

We expect to continue to incur substantial additional operating losses for at least the next several years as we continue to develop our product candidates and seek marketing approval and, subject to obtaining such approval, the eventual commercialization of our product candidates. If we obtain marketing approval for any of our product candidates, we will incur significant sales, marketing and manufacturing expenses. In addition, we expect to incur additional expenses to add operational, financial and information systems and personnel, including personnel to support our planned product commercialization efforts. We also expect to continue to incur significant costs to comply with corporate governance, internal controls and similar requirements associated with operating as a public reporting company.

Our future use of operating cash and capital requirements will depend on many forward-looking factors, including the following:

● the initiation, progress, timing, costs and results of preclinical studies and clinical trials for our product candidates;

● the clinical development plans we establish for these product candidates;

● the number and characteristics of product candidates that we may develop or in-license;

● the terms of any collaboration agreements we may choose to execute;

● the outcome, timing and cost of meeting regulatory requirements established by the FDA, the European Medicines Agency or other comparable foreign regulatory authorities;

● the cost of filing, prosecuting, defending and enforcing our patent claims and other intellectual property rights;

● the cost of defending intellectual property disputes, including patent infringement actions brought by third parties against us;

● costs and timing of the implementation of commercial scale manufacturing activities;

● the cost of establishing, or outsourcing, sales, marketing and distribution capabilities for any product candidates for which we may receive regulatory approval in regions where we choose to independently commercialize our products; and

● the extent to which health epidemics and other outbreaks of communicable diseases, including the ongoing COVID-19 pandemic, could disrupt our operations or materially and adversely affect our business and financial conditions.

To the extent that our capital resources are insufficient to meet our future operating and capital requirements, we will need to finance our cash needs through public or private equity offerings, debt financings, collaboration and licensing

25

arrangements or other financing alternatives. Additional equity or debt financing or collaboration and licensing arrangements may not be available on acceptable terms, if at all.

If we raise additional funds by issuing equity securities, including through the 2021 Sales Agreement, our stockholders may experience dilution.

Cash Flows

The following table summarizes our cash flows from operating, investing and financing activities for the six months ended June 30, 2022 and 2021.

	Six Months Ended June 30,
	2022		2021
Statement of Cash Flows Data:
Total net cash provided by (used in):
Operating activities	$	(7,683,007)	$	(15,576,797)
Investing activities		(51,607)		(47,570)
Financing activities		2,416,249		42,247,891
Net (decrease) increase in cash and cash equivalents	$	(5,318,365)	$	26,623,524

Operating Activities

For the six months ended June 30, 2022, cash used in operating activities was $7.7 million compared $15.6 million of cash used in operating activities for the six months ended June 30, 2021. The change from the comparable 2021 period was primarily due to the Company receiving payment of $8.0 million from the ATO for the non-AOF research and development incentive for the years ended December 31, 2018, 2019 and 2020. Our cash flows used in operations may differ substantially from our net loss due to non-cash charges and changes in balance sheet accounts.

Excluding the $8.0 million of cash received from the ATO in 2022, we expect cash used in operating activities to increase for the year ending December 31, 2022 as compared to 2021, as we continue to conduct our RECONNECT clinical trial for FXS.

Investing Activities

For the six months ended June 30, 2022 and 2021, cash used in investing activities represented the cost of expenditures made for manufacturing equipment.

Financing Activities

Cash provided by financing activities for the six months ended June 30, 2022 consisted of $2.4 million in net proceeds from sales of our shares of common stock under the 2021 Sales Agreement. Cash provided by financing activities for the six months ended June 30, 2021 consisted of $42.2 million in net proceeds from sales of our shares of common stock under the 2019 Sales Agreement.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements or relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities.

Recently Adopted Accounting Pronouncements

For descriptions of recently issued accounting pronouncements, see “Note 2 –Recent Accounting Pronouncements” of our Notes to Unaudited Consolidated Financial Statements included above in Part I of this Quarterly Report.

26

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to various market risks, which may result in potential losses arising from adverse changes in market rates, such as interest rates and foreign exchange rates. We do not enter into derivatives or other financial instruments for trading or speculative purposes nor do we engage in any hedging activities. As of June 30, 2022, we had cash and cash equivalents of $62.5 million, consisting primarily of cash and money market account balances. Because of the short-term maturities of our cash and cash equivalents, we do not believe that an immediate 10% increase in interest rates would have any significant impact on the realized value of our investments. Accordingly, we do not believe we are exposed to material market risk with respect to our cash and cash equivalents.

We have engaged third parties to manufacture our product candidates in Australia, Canada and the United Kingdom and to conduct clinical trials for our product candidates in the United States, Australia and New Zealand. Manufacturing and research costs related to these operations are paid for in a combination of U.S. dollars and local currencies, limiting our foreign currency exchange rate risk, however, our financial statements are reported in U.S. dollars and changes in foreign currency exchange rates could significantly affect our financial condition, results of operations, or cash flows. If we conduct clinical trials and seek to manufacture a more significant portion of our product candidates outside of the United States in the future, we could incur significant foreign currency exchange rate risk.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2022. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the rules and forms, promulgated by the Securities and Exchange Commission. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of June 30, 2022, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting during the three months ended June 30, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

We may become engaged in legal actions arising in the ordinary course of our business (such as, for example, proceedings relating to employment matters or the initiation or defense of proceedings relating to intellectual property rights) from time to time and, while there can be no assurance, we believe that the ultimate outcome of these legal actions will not have a material adverse effect on our business, results of operations, financial condition or cash flows.

Item 1A. Risk Factors.

You should carefully consider the risk factors described in our 2021 Annual Report under the caption “Item 1A. “Risk Factors,” as supplemented by our Quarterly Report on Form 10-Q for the three months ended March 31, 2022. There have been no material changes in our risk factors since we filed those reports. The risks described in those reports are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.

Nature of Business and Liquidity

Nature of Business and Liquidity

(1) Nature of Business and Liquidity

Zynerba Pharmaceuticals, Inc., together with its subsidiary, Zynerba Pharmaceuticals Pty Ltd (collectively, “Zynerba,” the “Company,” or “we”), is a clinical stage specialty pharmaceutical company focused on the development of pharmaceutically-produced transdermal cannabinoid therapies for orphan neuropsychiatric disorders, including Fragile X syndrome (“FXS”) and chromosome 22q11.2 deletion syndrome (“22q”). We have been granted orphan drug designations from the United States Food and Drug Administration (“FDA”) and the European Commission for the use of cannabidiol for the treatment of FXS. We have also been granted orphan drug designation from the FDA for the treatment of 22q. In addition, we have received Fast Track designation from the FDA for treatment of behavioral symptoms associated with FXS. The Company has decided to prioritize its resources on FXS and 22q, both of which have no approved products. While the data from the Company’s autism spectrum disorder (“ASD”) clinical development program to date are compelling, given the difficult financial market, the Company has decided to defer the start of the Phase 3 development program in ASD that was previously planned for the second half of 2022.

The Company has incurred losses and negative cash flows from operations since inception and has an accumulated deficit of $257.8 million as of June 30, 2022. 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 May 11, 2021, the Company entered into a Controlled Equity Offering^SM Sales Agreement (the “2021 Sales Agreement”) with Cantor Fitzgerald & Co., Canaccord Genuity, LLC, H.C. Wainwright & Co. LLC and Ladenburg Thalmann & Co. Inc., as sales agents (collectively, the “2021 Sales Agents”), pursuant to which, under a prospectus filed by the Company in May 2022, the Company may sell, from time to time, up to $75.0 million of its common stock. In the first half of 2022, the Company sold and issued 1,345,952 shares of common stock under the 2021 Sales Agreement in the open market at a weighted average selling price of $1.97 per share, resulting in gross proceeds of $2.7 million. Net proceeds after deducting commissions and offering expenses were $2.4 million. From July 1, 2022 through August 8, 2022, the Company sold and issued 1,469,714 shares of its common stock in the open market at a weighted average selling price of $1.19 per share, for gross proceeds of $1.8 million and net proceeds, after deducting commissions and offering expenses, of $1.6 million.

In August 2019, the Company entered into a Controlled Equity Offering^SM Sales Agreement (the “2019 Sales Agreement”) with Cantor Fitzgerald & Co., Canaccord Genuity, LLC, H.C. Wainwright & Co. LLC and Ladenburg Thalmann & Co. Inc., as sales agents (collectively, the “2019 Sales Agents”), pursuant to which the Company sold $75.0 million of its common stock. In the first quarter of 2021, the Company sold and issued 10,244,326 shares of common stock under the 2019 Sales Agreement in the open market at a weighted average selling price of $4.22 per share, resulting in gross proceeds of $43.2 million. Net proceeds after deducting commissions and offering expenses were $42.2 million. As of February 9, 2021, the Company had utilized the entire $75.0 million under the 2019 Sales Agreement.

Management believes that the Company’s cash and cash equivalents as of June 30, 2022 are sufficient to fund operations and capital requirements through the end of 2023 or early 2024, after the expected availability of top line results from its confirmatory pivotal Phase 3 RECONNECT trial of Zygel in patients with FXS. Substantial additional financings will be needed by the Company to fund its operations, and to complete clinical development of and to commercially develop its product candidates. The Company’s ability to raise sufficient additional financing depends on many factors beyond its control, including the current and ongoing volatility in the capital markets as a result of, among other factors, the COVID-19 pandemic and geopolitical tensions or the outbreak of hostilities or war. 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.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

(2) Summary of Significant Accounting Policies

a. Basis of Presentation

The accompanying unaudited interim consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. The interim unaudited consolidated financial statements have been prepared on the same basis as the consolidated financial statements as of and for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Annual Report”), filed with the Securities and Exchange Commission (the “SEC”). In the opinion of management, the accompanying consolidated financial statements of the Company include all normal and recurring adjustments (which consist primarily of accruals, estimates and assumptions that impact the consolidated financial statements) considered necessary to present fairly the Company's financial position as of June 30, 2022 its results of operations for the three and six months ended June 30, 2022 and 2021 and cash flows for the six months ended June 30, 2022 and 2021. Operating results for any interim period are not necessarily indicative of results for any future interim period or for the entire year. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the 2021 Annual Report.

b. Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of expenses during the reporting period. Actual results could differ from such estimates.

c. Incentive and Tax Receivables

The Company’s subsidiary, Zynerba Pharmaceuticals Pty Ltd (the “Subsidiary”), is incorporated in Australia. The Subsidiary is eligible to participate in an Australian research and development tax incentive program. As part of this program, the Subsidiary is eligible to receive a cash refund from the Australian Taxation Office (“ATO”) for a percentage of the research and development costs expended by the Subsidiary in Australia. The cash refund is available to eligible companies with an annual aggregate revenue of less than $20.0 million (Australian) during the reimbursable period. The Company estimates the amount of cash refund it expects to receive related to the Australian research and development tax incentive program and records the incentives when it is probable (1) the Company will comply with relevant conditions of the program and (2) the incentive will be received. The Company evaluates its eligibility under tax incentive programs as of each balance sheet date based on the most current and relevant data available. If the Company is deemed to be ineligible or unable to receive the Australian research and development tax credit, or the Australian government significantly reduces or eliminates the tax credit, the actual cash refund the Company receives may materially differ from its estimates.

In December 2018, the Company submitted an Advance Overseas Finding (“AOF”) application to a division of the Australian Government’s Department of Industry, Innovation and Science (“AusIndustry”), for a portion of the Company’s research and development activities incurred outside of Australia, which was approved by AusIndustry in July 2019. 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. In June 2020, the ATO informed the Company that it may not qualify for the AOF program based on their interpretation of certain eligibility requirements and, during the three months ended June 30, 2020, the Company determined it was no longer probable that the AOF claim would be received and the Company recorded a full reserve against the AOF receivable.

During the three months ended March 31, 2022, the Company concluded its conversations with the ATO on these matters and made the decision to no longer pursue the AOF claim, resulting in the write off of both the AOF receivable and the corresponding reserve during the period. During the three months ended March 31, 2022, the Company received a payment of $8.0 million from the ATO for the non-AOF research and development incentive for the years ended December 31, 2018, 2019 and 2020.

The Subsidiary incurs Goods and Services Tax (“GST”) on services provided by Australian vendors. As an Australian entity, the Subsidiary is entitled to a refund of the GST paid. The Company’s estimate of the amount of cash refund it expects to receive related to GST incurred is included in “Incentive and tax receivables” in the accompanying consolidated balance sheets. As of June 30, 2022, incentive and tax receivables included $0.3 million for refundable GST on expenses incurred with Australian vendors during the three months ended June 30, 2022.

Current incentive and tax receivables consisted of the following as of June 30, 2022 and December 31, 2021:

	June 30,		December 31,
	2022		2021
Research and development incentive (non-AOF) for the period 1/1/18 - 12/31/18	$	—	$	3,144,152

Goods and services tax		310,005		301,659
Total incentive and tax receivables before reserve for AOF		1,474,328		18,147,311

Total incentive and tax receivables - current assets	$	1,474,328	$	9,580,468

As of June 30, 2022, the Company’s estimate of the amount of cash refund it expects to receive for 2021 eligible spending as part of this incentive program was $1.2 million and was recorded as a current asset. The Company’s estimate of the amount of cash refund it expects to receive for 2022 eligible spending through June 30, 2022 was $0.6 million and was recorded as a non-current asset.

d. Research and Development

Research and development costs are expensed as incurred and are primarily comprised of external research and development expenses incurred under arrangements with third parties, such as contract research organizations, contract manufacturing organizations, consultants and employee-related expenses including salaries and benefits. At the end of each reporting period, the Company compares the payments made to each service provider to the estimated progress towards completion of the related project. Factors that the Company considers in preparing these estimates include the number of patients enrolled in studies, milestones achieved and other criteria related to the efforts of its vendors. These estimates will be subject to change as additional information becomes available. Depending on the timing of payments to vendors and estimated services provided, the Company will record net prepaid or accrued expenses related to these costs. Research and development expenses are recorded net of expected refunds of eligible research and development costs paid pursuant to the Australian research and development tax incentive program and GST incurred on services provided by Australian vendors.

The following table summarizes research and development expenses for the six months ended June 30, 2022 and 2021:

	Six months ended June 30,
	2022		2021
Research and development expenses - before R&D incentive	$	11,176,773	$	10,622,323
Research and development incentive		(583,851)		(561,365)
Total research and development expenses	$	10,592,922	$	10,060,958

e. Net Loss Per Share

Basic net loss per share is determined using the weighted average number of shares of common stock outstanding during each period. Diluted net income per share includes the effect, if any, from the potential exercise or conversion of securities, such as restricted stock and stock options, which would result in the issuance of incremental shares of

common stock. Basic and dilutive computations of net loss per share are the same in periods in which a net loss exists as the dilutive effects of restricted stock and stock options would be anti-dilutive.

The following potentially dilutive securities outstanding as of June 30, 2022 and 2021 have been excluded from the computation of diluted weighted average shares outstanding, as their effects on net loss per share for the periods presented would be anti-dilutive:

	June 30,
	2022	2021
Stock options	6,276,016	5,225,538
Unvested restricted stock	2,307,476	1,185,822
	8,583,492	6,411,360

f. Recent Accounting Pronouncements

The Company does not expect any recently issued accounting pronouncements to have a significant impact on its future results of operations, financial position or cash flow.

Fair Value Measurements

Fair Value Measurements

(3) Fair Value Measurements

The Company measures certain assets and liabilities at fair value in accordance with Accounting Standards

Codification (“ASC 820”), Fair Value Measurements and Disclosures. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability (the exit price) in an orderly transaction between market participants at the measurement date. The guidance in ASC 820 outlines a valuation framework and creates a fair value hierarchy that serves to increase the consistency and comparability of fair value measurements and the related disclosures. In determining fair value, the Company maximizes the use of quoted prices and observable inputs. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from independent sources. The fair value hierarchy is broken down into three levels based on the source of inputs as follows:

Level 1 — Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 — Valuations based on observable inputs and quoted prices in active markets for similar assets and liabilities.

Level 3 — Valuations based on unobservable inputs and models that are supported by little or no market activity.

In accordance with the fair value hierarchy described above, the following table sets forth the Company's financial assets measured at fair value on a recurring basis as of June 30, 2022 and December 31, 2021:

			Fair Value Measurement

Stock-Based Compensation

(8) Stock-Based Compensation

The Company maintains the Amended and Restated 2014 Omnibus Incentive Compensation Plan, as amended (the “2014 Plan”), which allows for the granting of incentive stock options, nonqualified stock options, stock appreciation rights, stock awards, stock units, performance units and other stock-based awards to employees, officers, non-employee directors, consultants, and advisors. In addition, the 2014 Plan provides selected executive employees with the opportunity to receive bonus awards that are considered qualified performance-based compensation. The 2014 Plan is subject to automatic annual increases in the number of shares authorized for issuance under the 2014 Plan on the first trading day of January each year equal to the lesser of 1.5 million shares or 10% of the number of shares of common stock outstanding on the last trading day of December of the preceding year. As of January 1, 2022, the number of shares of common stock that may be issued under the 2014 Plan was automatically increased by 1.5 million shares, increasing the total number of shares of common stock available for issuance under the 2014 Plan to 10,804,869 shares. As of June 30, 2022, 1,442,876 shares were available for future issuance under the 2014 Plan.

Options issued under the 2014 Plan have a contractual life of 10 years and may be exercisable in cash or as otherwise determined by the board of directors. The Company has granted options to employees and non-employee directors. Stock options granted to employees primarily vest 25% upon the first anniversary of the grant date and the balance of unvested options vests in quarterly installments over the remaining three years. Stock options granted annually to non-employee directors vest on the earlier of the one-year anniversary of the grant date, or the date of the Company’s next annual stockholders’ meeting that occurs after the grant date. The Company’s non-employee director compensation policy enables directors to receive stock options in lieu of quarterly cash payments. Any option granted to the directors in lieu of cash compensation vests in full on the grant date. The Company records forfeitures as they occur.

Stock-based compensation expense for performance-based grants are recorded when management estimates that the vesting of these shares is probable based on the status of the Company’s research and development programs and other relevant factors, which were established by the Company’s board of directors. The Company’s board of directors determines if the performance conditions have been met.

During the six months ended June 30, 2021, the Company granted 506,911 time-based restricted stock awards to employees with two-year cliff vesting of which 469,911 restricted stock awards remained outstanding as of June 30, 2022. In addition, during the six months ended June 30, 2021, the Company granted 506,911 performance-based restricted stock awards to employees of which 469,911 restricted stock awards remained outstanding as of June 30, 2022. The performance-based conditions for these performance-based grants were deemed probable of achievement during the six months ended June 30, 2021 and, as of June 30, 2022, the Company has recorded $1.6 million in stock-based compensation expense related to these grants. As of June 30, 2022, there was $0.1 million of unrecognized stock-based compensation expense related to these performance-based awards, which will be expensed over the estimated service period related to each performance condition.

During the six months ended June 30, 2022, the Company granted 841,654 time-based restricted stock awards to employees, non-employee directors and consultants of which 824,654 restricted stock awards remained outstanding as of June 30, 2022. In addition, during the six months ended June 30, 2022, the Company granted 556,500 performance-based restricted stock awards to employees of which 548,000 restricted stock awards remained outstanding as of June 30, 2022. As of June 30, 2022, none of the performance-based metrics were deemed probable of achievement.

For the six months ended June 30, 2022 and 2021, the Company recorded stock-based compensation expense related to its stock option grants and restricted stock awards, as follows:

	Stock Option Grants				Restricted stock awards				Total
	2022		2021		2022		2021		2022			2021

As of June 30, 2022, there was $4.4 million of unrecognized stock-based compensation expense related to stock options, which is expected to be recognized over a weighted-average period of 2.57 years. During the six months ended June 30, 2021, the Company received $47,906 in cash from the exercise of employee stock options.

The following table summarizes the Company’s restricted stock award activity under the 2014 Plan for the six months ended June 30, 2022:

(9) Operating Lease Obligations

The Company adopted Accounting Standards Update No. 2016-02, Leases (Topic 842), Accounting Standards Codification 842 prospectively using the modified-retrospective method and elected the package of transition practical expedients that does not require reassessment of: (1) whether any existing or expired contracts are or contain leases, (2) lease classification and (3) initial direct costs. In addition, the Company has elected other available practical expedients to not separate lease and nonlease components, which consist principally of common area maintenance charges, and to exclude leases with an initial term of 12 months or less.

The Company leases its headquarters where it occupies 10,877 square feet of office space. On March 1, 2021, the Company extended its lease for three additional years until May 31, 2024. The Company’s lease contains variable lease costs that do not depend on a rate or index and consist primarily of common area maintenance, taxes, and insurance charges. As the implicit rate was not readily determinable for the Company’s lease, the Company used an estimated incremental borrowing rate, or discount rate, to determine the initial present value of the lease payments. The discount rate for the lease was calculated using a synthetic credit rating model.

As of March 1, 2021, the effective date of the lease modification, the Company remeasured the lease liability for the remaining portion of the lease and adjusted the lease liability to $755,085 and right-of-use assets to $752,391, which was recorded net of a deferred rent liability of $2,694. As of June 30, 2022, the Company’s right-of-use asset, net of amortization, was $451,800.

Common Stock Purchase Agreement – Lincoln Park Equity Line of Credit

On July 21, 2022 (the “Effective Date”), the Company entered into a Purchase Agreement (the “Purchase Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”), pursuant to which the Company has the right, but not the

obligation, to sell to Lincoln Park, and Lincoln Park is obligated to purchase, up to $20.0 million of the Company’s common stock. Such sales of common stock by the Company, if any, will be subject to certain limitations, and may occur from time to time, at the Company’s sole discretion, over the 36-month period commencing on the Effective Date. Pursuant to the terms of the Purchase Agreement, the Company issued 347,222 shares of its common stock to Lincoln Park as consideration for its commitment to purchase shares of the Company’s common stock under the Purchase Agreement.

Concurrently with entering into the Purchase Agreement, the Company also entered into a registration rights agreement with Lincoln Park (the “Registration Rights Agreement”) pursuant to which the Company agreed to register the sale of the shares of the Company’s common stock that have been and may be issued to Lincoln Park under the Purchase Agreement pursuant to the Company’s existing shelf registration statement on Form S-3 (File No. 333-264966) or a new registration statement.

The number of shares the Company may sell to Lincoln Park on any single business day in a regular purchase is 150,000 shares, but that amount may be increased up to 300,000 shares, depending upon the closing price of the Company’s common stock on the Nasdaq Global Market (“Nasdaq”) and subject to a maximum limit of $2.0 million per regular purchase. The purchase price per share for each such regular purchase will be based on prevailing market prices of the Company’s common stock immediately preceding the time of sale as computed under the Purchase Agreement. In addition to regular purchases, the Company may also direct Lincoln Park to purchase other amounts as accelerated purchases or as additional accelerated purchases.

Under applicable rules of Nasdaq, in no event may the Company issue or sell to Lincoln Park under the Purchase Agreement shares of its common stock, including the Commitment Shares, in excess of 8,898,867 shares, which is equal to 19.99% of the shares of the Company’s common stock outstanding immediately prior to the execution of the Purchase Agreement (the “Exchange Cap”) unless (i) the Company obtains stockholder approval to issue shares of its common stock in excess of the Exchange Cap or (ii) the average price of all shares of the Company’s common stock issued to Lincoln Park under the Purchase Agreement equals or exceeds $1.13 per share (which represents the average of the official closing prices of the Company’s common stock on Nasdaq for the five (5) trading days immediately preceding the signing of the Purchase Agreement), such that the transactions contemplated by the Purchase Agreement are exempt from the Exchange Cap limitation under applicable Nasdaq rules. In any event, the Purchase Agreement specifically provides that the Company may not issue or sell any shares of its common stock under the Purchase Agreement if such issuance or sale would breach any applicable rules or regulations of the Nasdaq.

Actual sales of shares of common stock to Lincoln Park under the Purchase Agreement will depend on a variety of factors to be determined by the Company from time to time, including, among others, market conditions, the trading price of the Company’s common stock and determinations by the Company as to the appropriate sources of funding for the Company and its operations. The Company may not sell shares of its common stock to Lincoln Park under the Purchase Agreement if doing so would result in Lincoln Park beneficially owning more than 9.99% of the Company’s common stock.

The net proceeds, if any, under the Purchase Agreement will depend on the frequency and prices at which the Company sells shares of its common stock to Lincoln Park. The Company intends to use any net proceeds from the sale of its common stock to Lincoln Park for working capital and general corporate purposes, including research and development expenses and capital expenditures. The Company also agreed to reimburse Lincoln Park for a limited portion of the legal fees it incurred in connection with the Purchase Agreement.

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of expenses during the reporting period. Actual results could differ from such estimates.

Incentive and Tax Receivables

c. Incentive and Tax Receivables

The Company’s subsidiary, Zynerba Pharmaceuticals Pty Ltd (the “Subsidiary”), is incorporated in Australia. The Subsidiary is eligible to participate in an Australian research and development tax incentive program. As part of this program, the Subsidiary is eligible to receive a cash refund from the Australian Taxation Office (“ATO”) for a percentage of the research and development costs expended by the Subsidiary in Australia. The cash refund is available to eligible companies with an annual aggregate revenue of less than $20.0 million (Australian) during the reimbursable period. The Company estimates the amount of cash refund it expects to receive related to the Australian research and development tax incentive program and records the incentives when it is probable (1) the Company will comply with relevant conditions of the program and (2) the incentive will be received. The Company evaluates its eligibility under tax incentive programs as of each balance sheet date based on the most current and relevant data available. If the Company is deemed to be ineligible or unable to receive the Australian research and development tax credit, or the Australian government significantly reduces or eliminates the tax credit, the actual cash refund the Company receives may materially differ from its estimates.

In December 2018, the Company submitted an Advance Overseas Finding (“AOF”) application to a division of the Australian Government’s Department of Industry, Innovation and Science (“AusIndustry”), for a portion of the Company’s research and development activities incurred outside of Australia, which was approved by AusIndustry in July 2019. 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. In June 2020, the ATO informed the Company that it may not qualify for the AOF program based on their interpretation of certain eligibility requirements and, during the three months ended June 30, 2020, the Company determined it was no longer probable that the AOF claim would be received and the Company recorded a full reserve against the AOF receivable.

During the three months ended March 31, 2022, the Company concluded its conversations with the ATO on these matters and made the decision to no longer pursue the AOF claim, resulting in the write off of both the AOF receivable and the corresponding reserve during the period. During the three months ended March 31, 2022, the Company received a payment of $8.0 million from the ATO for the non-AOF research and development incentive for the years ended December 31, 2018, 2019 and 2020.

The Subsidiary incurs Goods and Services Tax (“GST”) on services provided by Australian vendors. As an Australian entity, the Subsidiary is entitled to a refund of the GST paid. The Company’s estimate of the amount of cash refund it expects to receive related to GST incurred is included in “Incentive and tax receivables” in the accompanying consolidated balance sheets. As of June 30, 2022, incentive and tax receivables included $0.3 million for refundable GST on expenses incurred with Australian vendors during the three months ended June 30, 2022.

Current incentive and tax receivables consisted of the following as of June 30, 2022 and December 31, 2021:

	June 30,		December 31,
	2022		2021
Research and development incentive (non-AOF) for the period 1/1/18 - 12/31/18	$	—	$	3,144,152

Total incentive and tax receivables - current assets	$	1,474,328	$	9,580,468

As of June 30, 2022, the Company’s estimate of the amount of cash refund it expects to receive for 2021 eligible spending as part of this incentive program was $1.2 million and was recorded as a current asset. The Company’s estimate of the amount of cash refund it expects to receive for 2022 eligible spending through June 30, 2022 was $0.6 million and was recorded as a non-current asset.

Research and Development

d. Research and Development

Research and development costs are expensed as incurred and are primarily comprised of external research and development expenses incurred under arrangements with third parties, such as contract research organizations, contract manufacturing organizations, consultants and employee-related expenses including salaries and benefits. At the end of each reporting period, the Company compares the payments made to each service provider to the estimated progress towards completion of the related project. Factors that the Company considers in preparing these estimates include the number of patients enrolled in studies, milestones achieved and other criteria related to the efforts of its vendors. These estimates will be subject to change as additional information becomes available. Depending on the timing of payments to vendors and estimated services provided, the Company will record net prepaid or accrued expenses related to these costs. Research and development expenses are recorded net of expected refunds of eligible research and development costs paid pursuant to the Australian research and development tax incentive program and GST incurred on services provided by Australian vendors.

The following table summarizes research and development expenses for the six months ended June 30, 2022 and 2021:

	Six months ended June 30,
	2022		2021
Research and development expenses - before R&D incentive	$	11,176,773	$	10,622,323
Research and development incentive		(583,851)		(561,365)
Total research and development expenses	$	10,592,922	$	10,060,958

Net Loss Per Share

e. Net Loss Per Share

Basic net loss per share is determined using the weighted average number of shares of common stock outstanding during each period. Diluted net income per share includes the effect, if any, from the potential exercise or conversion of securities, such as restricted stock and stock options, which would result in the issuance of incremental shares of

common stock. Basic and dilutive computations of net loss per share are the same in periods in which a net loss exists as the dilutive effects of restricted stock and stock options would be anti-dilutive.

The following potentially dilutive securities outstanding as of June 30, 2022 and 2021 have been excluded from the computation of diluted weighted average shares outstanding, as their effects on net loss per share for the periods presented would be anti-dilutive:

	June 30,
	2022	2021
Stock options	6,276,016	5,225,538
Unvested restricted stock	2,307,476	1,185,822
	8,583,492	6,411,360
