PDS BIOTECHNOLOGY CORPORATION AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1 – Nature of Operations

PDS Biotechnology Corporation, a Delaware corporation (the “Company” or “PDS”), is a clinical-stage immunotherapy company developing a growing pipeline of cancer immunotherapies and infectious disease vaccines designed to overcome the well-established limitations of current immunotherapy technologies.  PDS owns Versamune®, a proprietary T-cell activating platform designed to train the immune system to better attack and destroy disease. When paired with an antigen, which is a disease-related protein that is recognizable by the immune system, Versamune® has been shown to induce, in vivo, large quantities of high-quality, highly potent polyfunctional CD8+ killer T-cells, a specific sub-type of CD8+ killer T-cell that is more effective at killing infected or target cells. Our immuno-oncology products can potentially be used as a component of combination products with other leading technologies to provide effective treatments across a range of advanced cancer types. We believe our product candidates are of interest for potential treatments in relation to Human Papillomavirus (HPV)-associated cancers, melanoma, colorectal, lung, breast and prostate cancers or as monotherapies in early-stage disease.  PDS is working to progress its infectious disease development program, which includes novel vaccines for COVID-19 and universal influenza.

From the Company’s inception, it has devoted substantially all of its efforts to drug development, business planning, engaging regulatory, manufacturing and other technical consultants, acquiring operating assets, planning and executing clinical trials and raising capital.

In December 2019, a novel (new) coronavirus known as SARS-CoV-2 was first detected in Wuhan, Hubei Province, People’s Republic of China, causing outbreaks of the coronavirus disease, known as COVID-19, that has now spread globally. On January 30, 2020, the World Health Organization (WHO) declared COVID-19 a public health emergency. The Secretary of Health and Human Services declared a public health emergency on January 31, 2020, under section 319 of the Public Health Service Act (42 U.S.C. 247d), in response to the COVID-19 outbreak. On March 11, 2020, the WHO declared COVID-19 a pandemic and on March 13 the President declared a national emergency in response to the pandemic. We continue to learn more about the full impact of the COVID-19 pandemic which has continued to evolve due to the emergence of variants of concern, resulting in new waves of infection regionally and globally. The COVID-19 pandemic has and could continue to negatively affect the Company’s liquidity and operations.  To date, two of the three recently initiated PDS0101 clinical trials were delayed, specifically as a result of the adverse impact the COVID-19 pandemic has had on clinical trial operations for cancer indications in the United States. The FDA issued and has since updated guidance to assist sponsors in assuring the safety of trial participants, maintaining compliance with Good Clinical Practice (GCP) and minimizing risks to trial integrity.  Clinical trial sites have implemented institution-specific measures securing the safety of patients and staff to ensure the integrity of the trials in the face of the ongoing pandemic. All three studies have since been initiated despite the pandemic challenges; however, the evolving COVID-19 pandemic has impacted the pace of enrollment in clinical trials in general and we may be negatively affected with our trials. COVID-19 related travel and other restrictions may also impact the potential for on-site monitoring visiting and audits and inspections by us, third parties, and government regulators. There may be shortages of site personnel and equipment necessary for the timely completion of our trials. We are providing support to address these challenges, but these mitigation measures may not overcome the obstacles that the pandemic has wrought which continue to impede progress of clinical trials.

Although there is uncertainty related to the anticipated impact of the COVID-19 pandemic on our future results, we believe our current cash reserves leave us well-positioned to manage our business through this crisis as it continues to unfold. However, the impacts of the COVID-19 pandemic are broad-reaching and continuing and the financial impacts associated with the COVID-19 pandemic are still uncertain.

Note 2 – Summary of Significant Accounting Policies

(A) Unaudited interim financial statements:

The interim balance sheet at June 30, 2021, the statements of operations and comprehensive loss and changes in stockholders’ equity for the three and six months ended June 30, 2021 and 2020, and cash flows for the six months ended June 30, 2021 and 2020 are unaudited. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP, in accordance with the requirements of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. GAAP can be condensed or omitted. These condensed consolidated financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments that are necessary for a fair statement of its financial information. The results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the year ending December 31, 2021 or for any other future annual or interim period. The balance sheet as of December 31, 2020 included herein was derived from the audited condensed consolidated financial statements as of that date. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2020, filed by the Company with the SEC in its Annual Report on Form 10-K on March 18, 2021.

(B) Use of estimates:

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of expenses at the date of the consolidated financial statements and during the reporting periods, and to disclose contingent assets and liabilities at the date of the consolidated financial statements. Actual results could differ from those estimates.

(C) Significant risks and uncertainties:

The Company’s operations are subject to a number of factors that may affect its operating results and financial condition. Such factors include, but are not limited to: the clinical and regulatory development of its products, the Company’s ability to preserve its cash resources, the Company’s review of strategic alternatives, the Company’s ability to add product candidates to its pipeline, the Company’s intellectual property, the ability to efficiently and effectively conduct its clinical trials, competition from products manufactured and sold or being developed by other companies, the price of, and demand for, Company products if approved for sale, the Company’s ability to negotiate favorable licensing or other manufacturing and marketing agreements for its products, the Company’s ability to raise capital, and the effects of health epidemics, pandemics, or outbreaks of infectious diseases, including the recent COVID-19 pandemic.

The Company currently has no commercially approved products. As such, there can be no assurance that the Company’s future research and development programs will be successfully commercialized. Developing and commercializing a product requires significant time and capital and is subject to regulatory review and approval as well as competition from other biotechnology and pharmaceutical companies. The Company operates in an environment of rapid change and is dependent upon the continued services of its employees and consultants and obtaining and protecting its intellectual property.

(D) Cash equivalents and concentration of cash balance:

The Company considers all highly liquid securities with a maturity weighted average of less than three months to be cash equivalents. The Company’s cash and cash equivalents in bank deposit accounts, at times, may exceed federally insured limits.

9

(E) Research and development:

Costs incurred in connection with research and development activities are expensed as incurred. These costs include licensing fees to use certain technology in the Company’s research and development projects as well as fees paid to consultants and entities that perform certain research and testing on behalf of the Company.

Costs for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using data, such as patient enrollment, clinical site activations or information provided by vendors on their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred.

(F) Patent costs:

The Company expenses patent costs as incurred and classifies such costs as general and administrative expenses in the accompanying statements of operations and comprehensive loss.

(G) Stock-based compensation:

The Company accounts for its stock-based compensation in accordance with ASC Topic 718, Compensation—Stock Compensation (“ASC 718”). ASC 718 requires all stock-based payments to employees, directors and non-employees to be recognized as expense in the consolidated statements of operations and comprehensive loss based on their grant date fair values. In order to determine the fair value of stock options on the date of grant, the Company uses the Black-Scholes option-pricing model. Inherent in this model are assumptions related to expected stock-price volatility, option term, risk-free interest rate and dividend yield. While the risk-free interest rate and dividend yield are less subjective assumptions that are based on factual data derived from public sources, the expected stock-price volatility and option term assumptions require a greater level of judgment. The Company expenses the fair value of its stock-based compensation awards to employees and directors on a straight-line basis over the requisite service period, which is generally the vesting period. The Company recognizes forfeitures as they occur.

(H) Net income (loss) per common share:

Basic and diluted net loss per common share is determined by dividing net loss attributable to common stockholders by the weighted average common shares outstanding during the period. For all periods presented, the common shares underlying the preferred stock, common stock options and warrants have been excluded from the calculation because their effect would be anti-dilutive. Therefore, the weighted average shares outstanding used to calculate both basic and diluted loss per common share are the same.

The potentially dilutive securities excluded from the determination of diluted loss per share as their effect is antidilutive, are as follows:

	As of June 30,
	2021		2020
Stock options to purchase Common Stock		3,209,248		1,639,753
Warrants to purchase Common Stock		197,518		197,518
Total		3,406,766		1,837,271

Note 3 – Liquidity

As of June 30, 2021, the Company had $74.7 million of cash and cash equivalents. The Company’s primary uses of cash are to fund operating expenses, primarily research and development expenditures. Cash used to fund operating expenses is impacted by the timing of when the Company pays these expenses, as reflected in the change to the Company’s outstanding accounts payable and accrued expenses.

On July 29, 2019, we entered into a common stock purchase agreement, or the Aspire Purchase Agreement, with Aspire Capital pursuant to which, we have the right, in our sole discretion, to present Aspire Capital Fund, LLC, or Aspire Capital, with a purchase notice, directing Aspire Capital (as principal) to purchase up to 100,000 shares of our common stock per business day, in an aggregate amount of up to $20.0 million of our common stock, or the Purchased Shares, over the term of the Aspire Purchase Agreement. We may sell an aggregate of 1,034,979 shares of our common stock (which represented 19.99% of our outstanding shares of common stock on the date of the Aspire Purchase Agreement) without stockholder approval. We may sell additional shares of our common stock above the 19.99% limit provided that (i) we obtain stockholder approval or (ii) stockholder approval has not been obtained at any time the 1,034,979 share limitation is reached and at all times thereafter the average price paid for all shares issued under the Aspire Purchase Agreement, is equal to or greater than $5.76, which was the consolidated closing bid price of our common stock on July 26, 2019. The minimum price at which we can sell shares under the Aspire Purchase Agreement is $0.50. On July 29, 2019, we issued 100,654 shares of our common stock to Aspire Capital, as consideration for entering into the Aspire Purchase Agreement, which we refer to as the Commitment Shares. We recorded the fair value of the shares at July 29, 2019 of $603,924 as an expense in the third quarter of 2019. Concurrently with the Aspire Purchase Agreement, we entered into a registration rights agreement with Aspire Capital, or the Registration Rights Agreement. In accordance with the Registration Rights Agreement, on August 20, 2019 we filed a Registration Statement on Form S-1 (File No. 333-232988) to cover the resale of the Commitment Shares and any Purchased Shares issuable to Aspire Capital under the Aspire Purchase Agreement. There is market uncertainty regarding the utilization of financing associated from the Aspire Purchase Agreement. As of June 30, 2021, no Purchase Shares have been sold to Aspire Capital under the Aspire Purchase Agreement.

In February 2020, we completed an underwritten public offering, in which we sold 10,000,000 shares of common stock at a public offering price of $1.30 per share. The shares sold included 769,230 shares issued upon the exercise by the underwriter of its option to purchase additional shares at the public offering price, minus underwriting discounts and commissions. We received gross proceeds of approximately $13 million and net proceeds of approximately $11.9 million after deducting underwriting discounts and commissions.

In July 2020, we filed a shelf registration statement, or the 2020 Shelf Registration Statement, with the SEC, for the issuance of common stock, preferred stock, warrants, rights, debt securities and units, which we refer to collectively as the Shelf Securities, up to an aggregate amount of $100 million. The 2020 Shelf Registration Statement was declared effective on July 31, 2020.

In August 2020, the Company sold 6,900,000 shares of its common stock at a public offering price of $2.75 per share pursuant to the 2020 Shelf Registration Statement, which includes 900,000 shares issued upon the exercise by the underwriter of its option to purchase additional shares at the public offering price, minus underwriting discounts and commissions. We received gross proceeds of approximately $19.0 million and net proceeds of approximately $17.1 million, after deducting underwriting discounts and offering expenses.

In May 2021, we received approximately $4.5 million from the net sale of tax benefits to an unrelated, profitable New Jersey corporation pursuant the Company’s participation in the New Jersey Technology Business Tax Certificate Transfer Net Operating Loss (NOL) program for State Fiscal Year 2020.

In June 2021, we completed an underwritten public offering in which we sold 6,088,235 shares of common stock at a public offering price of $8.50 per share pursuant to the 2020 Shelf Registration Statement, which includes 794,117 shares issued upon the exercise by the underwriter of its option to purchase additional shares at the public offering price, minus underwriting discounts and commissions. We received gross proceeds of approximately $51.7 million and net proceeds of approximately $48.5 million, after deducting underwriting discounts and offering expenses. Approximately $29,300,000 of Shelf Securities remain available for future sale under the 2020 Shelf Registration Statement.

Our primary uses of cash are to fund operating expenses, primarily research and development expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable and accrued expenses.

We evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year beyond the filing of this Quarterly Report on Form 10-Q.  Our budgeted cash requirements in 2021 and beyond include expenses related to continuing development and clinical studies.  Based on our available cash resources and cash flow projections as of the date the consolidated financial statements were available for issuance, we believe there are sufficient funds to continue operations and research and development programs for at least 12 months from the date of this report.

We plan to continue to fund our operations and capital funding needs through equity and/or debt financings. However, the Company cannot be certain that additional financing will be available when needed or that, if available, financing will be obtained on terms favorable to the Company or its existing stockholders.  We may also enter into government funding programs and consider selectively partnering for clinical development and commercialization. The sale of additional equity would result in additional dilution to our stockholders. Incurring debt financing would result in debt service obligations, and the instruments governing such debt could provide for operating and financing covenants that would restrict our operations. If we are unable to raise additional capital in sufficient amounts or on acceptable terms, we may be required to delay, limit, reduce, or terminate our product development or future commercialization efforts or grant rights to develop and market immunotherapies that we would otherwise prefer to develop and market ourselves. Any of these actions could harm our business, results of operations and prospects. Failure to obtain adequate financing also may adversely affect our ability to operate as a going concern.

Note 5 – Leases

On July 8, 2019, the Company entered into a lease termination agreement for its office space located at 300 Connell Drive, Suite 4000, Berkeley Heights, NJ 07922 effective August 31, 2019 (the “Lease Termination Agreement”). Pursuant to the Lease Termination Agreement, the Company was required to pay 50 percent of the remaining lease payments of $665,802 over three installments on September 1, 2019, December 1, 2019, and March 1, 2020, which was recorded as lease termination costs in the third quarter of 2019. The Company entered into a temporary month-to-month lease as of September 1, 2019 for office space located at 830 Morris Turnpike, Short Hills, NJ 07078 until the Company entered into a new lease for permanent office space. This lease was terminated on May 31, 2020.

Effective March 5, 2020, the Company entered into a sublease for approximately 11,200 square feet of office space located at 25B Vreeland Road, Suite 300, Florham Park, NJ. The sublease commenced on May 1, 2020 and will continue for a term of forty (40) months with an option to renew through October 31, 2027. As of June 30, 2021 there are twenty-six (26) months remaining in the lease term. Upon inception of the lease, the Company recognized approximately $0.7 million of a ROU asset and operating lease liabilities. The discount rate used to measure the operating lease liability as of May 1, 2020 was 9.15%. Throughout the period described above the Company has maintained, and continues to maintain, a month-to-month lease for its research facilities at the Princeton Innovation Center BioLabs located at 303A College Road E, Princeton NJ, 08540.

Note 7 – Stock-Based Compensation

The Company has three equity compensation plans: the 2009 Stock Option Plan, 2014 Equity Incentive Plan and the 2018 Stock Incentive Plan (the “Plans”).

In 2014, the Company’s stockholders approved the 2014 Equity Incentive Plan pursuant to which the Company may grant up to 91,367 shares as ISOs, NQs and restricted stock units (“RSUs”), subject to increases as hereafter described (the “Plan Limit”). In addition, on January 1, 2015 and each January 1 thereafter and prior to the termination of the 2014 Equity Incentive Plan, pursuant to the terms of the 2014 Equity Incentive Plan, the Plan Limit was and shall be increased by the lesser of (x) 4% of the number of shares of Common Stock outstanding as of the immediately preceding December 31 and (y) such lesser number as the Board of Directors may determine in its discretion. In March 2019, the Plan was amended and restated which removed the annual increase component and was limited to 826,292 shares.

As previously disclosed, on December 8, 2020, the Board of Directors of the Company adopted, subject to stockholder approval, the Second Amended and Restated PDS Biotechnology Corporation 2014 Equity Inventive Plan (the “Restated Plan”), which would amend and restate the Amended and Restated PDS Biotechnology Corporation 2014 Equity Incentive Plan (the “Current Plan”). The Company held its annual meeting of stockholders on June 17, 2021 (the “Annual Meeting”).  The stockholders voted to approve the Restated Plan at the Annual Meeting.  The Restated Plan is identical to the Current Plan in all material respects, except as follows: (a) the number of shares of Common Stock authorized for issuance under the Restated Plan will increase from 826,292 shares to 3,339,243 shares, plus the total number of shares that remained available for issuance, that are not covered by outstanding awards issued under the Current Plan, immediately prior to December 8, 2020; and (b) the Restated Plan will terminate on December 7, 2030, unless earlier terminated. Please reference the disclosure in Note 9 of this Quarterly Report on Form 10-Q for further disclosure regarding the Restated Plan.

In 2018, the Company’s stockholders approved the 2018 Stock Incentive Plan pursuant to which the Company may grant up to 558,071 shares as (i) Stock Options, (ii) Stock Appreciation Rights, (iii) Restricted Stock, (iv) Preferred Stock, (v) Stock Reload Options and/or (vi) Other Stock-Based Awards.

13

 Pursuant to the terms of the Plans, ISOs have a term of ten years from the date of grant or such shorter term as may be provided in the option agreement. Unless specified otherwise in an individual option agreement, ISOs generally vest over a four year term and NQs generally vest over a  one to five year terms. Unless terminated by the Board, the Plans shall continue to remain effective for a term of ten years or until such time as no further awards may be granted and all awards granted under the Plans are no longer outstanding. As of June 30, 2021, there were 190,799 shares available for grant under the 2018 Stock Incentive Plan.

 On June 17, 2019, the Board adopted the 2019 Inducement Plan (the “Inducement Plan”). The Inducement Plan provides for the grant of non-qualified stock options. The Inducement Plan was recommended for approval by the Compensation Committee of the Board and subsequently approved and adopted by the Board without stockholder approval pursuant to Rule 5635(c)(4) of the Nasdaq Listing Rules.

On December 9, 2020, the Company amended the Inducement Plan solely to increase the total number of shares of Common Stock reserved for issuance under the Inducement Plan from 200,000 shares to 500,000 shares. The 2019 Inducement Plan is administered by the Compensation Committee of the Board. In accordance with Rule 5635(c)(4) of the Nasdaq Listing Rules, non-qualified stock options under the 2019 Inducement Plan may only be made to an employee who has not previously been an employee or member of the Board (or any parent or subsidiary of the Company), or following a bona fide period of non-employment by the Company (or a parent or subsidiary of the Company), if he or she is granted such non-qualified stock options in connection with his or her commencement of employment with the Company or a subsidiary and such grant is an inducement material to his or her entering into employment with the Company or such subsidiary. As of June 30, 2021, there were 223,700 shares available for grant under the 2019 Inducement Plan.

The Company’s stock-based compensation expense related to stock options was recognized in operating expense as follows:

At June 30, 2021 there was approximately $11,174,767 of unamortized stock option compensation expense, which is expected to be recognized over a remaining average vesting period of 3.20 years.

Note 8 – Income Taxes

In assessing the realizability of the net deferred tax assets, the Company considers all relevant positive and negative evidence to determine whether it is more likely than not that some portion or all of the deferred income tax assets will not be realized. The realization of the gross deferred tax assets is dependent on several factors, including the generation of sufficient taxable income prior to the expiration of the net operating loss carryforwards. The Company expects to have a loss for 2021 and there will be no current income tax expense. Additionally, there was a full valuation allowance against the net deferred tax assets as of June 30, 2021 and December 31, 2020. In May 2021, in accordance with the State of New Jersey’s Technology Business Tax Certificate Program, which allowed certain high technology and biotechnology companies to sell unused NOL carryforwards to other New Jersey-based corporate taxpayers, the Company sold New Jersey NOL carryforwards, resulting in the recognition of $4.5 million of income tax benefit, net of transaction costs.

The Company’s U.S. statutory rate is 21%. The effective tax rate, excluding the benefit of the sale of any New Jersey net operating losses, for the three and six months ended June 30, 2021 is 0%.  The primary factor impacting the effective tax rate is the anticipated full year operating loss which will require a full valuation allowance against any associate deferred tax asset.

Entities are also required to evaluate, measure, recognize and disclose any uncertain income tax provisions taken on their income tax returns. The Company has analyzed its tax positions and has concluded that as of June 30, 2021, there were no uncertain positions. The Company’s U.S. federal and state net operating losses have occurred since its inception and as such, tax years subject to potential tax examination could apply from that date because the utilization of net operating losses from prior years opens the relevant year to audit by the IRS and/or state taxing authorities. The Company did not have any unrecognized tax benefits and has not accrued any interest or penalties for the three and six months ended June 30, 2021 and for the year ended December 31, 2020.

Note 9 – Commitments and Contingencies

Rent

For month-to-month arrangements not impacted by the adoption of ASC 842, rent for the three and six months ended June 30, 2021 was $42,477 and $78,493, respectively, compared to the three and six months ended June 30, 2020 of $46,337 and $104,978.

Legal Proceedings

On July 23, 2021, David R. Rosener, a purported stockholder of PDS, filed a putative class action and shareholder derivative complaint in the Court of Chancery of the State of Delaware (C.A. No. 2021-0644 JRS)  against PDS and all of our directors and certain of our executive officers. The plaintiff named all current directors of PDS as defendants as well as PDS’s Chief Scientific Officer and Chief Medical Officer as defendants and also named PDS as a nominal defendant.  The plaintiff claims that PDS’s bylaws required tabulation of broker non-votes on Proposal 3 of the proxy, which sought shareholder approval of the Second Amended and Restated PDS Biotechnology Corporation 2014 Equity Incentive Plan (the “Restated Plan”) that was voted upon at the 2021 annual stockholder meeting on June 17, 2021.  In addition, the complaint asserts claims for breach of fiduciary duties, declaratory judgment, waste of corporate assets and unjust enrichment in connection with the Restated Plan and the granting of an aggregate award of 1,040,700 stock options to certain executive officers pursuant to the Restated Plan.  The plaintiff seeks unspecified monetary damages, seeks to have the Restated Plan declared void, and seeks recission of the grant of stock options as ultra vires.  Given the early stage of this lawsuit, PDS is unable to reasonably estimate the costs associated with the lawsuit or predict the outcome.  Each of the Company, its directors and the named executives intend to defend this action vigorously.  There can be no guarantee as to the timing of any resolution.

Note 10 – Retirement Plan

The Company has a 401(k) defined contribution plan for the benefit for all employees and permits voluntary contributions by employees subject to IRS-imposed limitations. The 401(k) employer contributions were $0 and $35,747 for the three and six months ended June 30, 2021, respectively, compared to the three and six months ended June 30, 2020 of $10,168 and $19,967, respectively.

Company Overview

We are a clinical-stage immunotherapy company developing a growing pipeline of cancer immunotherapy and infectious disease vaccine candidates designed to overcome the limitations of current immunotherapy technologies. Our Versamune^® technology is a proprietary T-cell activating platform designed to train the immune system to better attack and destroy disease. When paired with an antigen (which is a disease-related protein that is recognizable by the immune system) Versamune^® induces, in vivo, large quantities of high-quality, highly potent polyfunctional CD8+ killer T-cells, a specific sub-type of T-cell that is more effective at killing infected or targeted cancer cells. Versamune^® has also been shown in pre-clinical studies to induce antigen-specific highly potent polyfunctional CD4+ helper T-cells as well as neutralizing antibodies. PDS0101 in its first human clinical trial provided data supporting the earlier promising preclinical study results and demonstrated the unique in vivo induction of high levels of active HPV-specific CD8+ T-cells in humans.  Positive preliminary clinical results of PDS0101 in combination with investigational immune-modulating agents Bintrafusp alfa (M7824), and NHS-IL12 (M9241), discussed in more detail below, suggest that PDS0101 induction of in vivo highly active tumor-attacking HPV16 killer (CD8+) T-cells even in extensively treated and immunologically limited patients has the potential for effective disease reduction and ongoing responses.

We believe that the Versamune® platform has the potential to become an industry-leading immuno-oncology technology, It is currently being applied to the development of a robust pipeline of valuable “new-generation, multi-functional” immunotherapies, potentially as single agents and as part of combination therapies with other leading immuno-oncology technologies and standard of care therapies. We believe our product candidates could be of interest for potential combination therapies in relation to advanced, recurrent or metastatic HPV-associated cancers, melanoma, colorectal, lung, breast and prostate cancers or as monotherapies in earlier-stage disease.

PDS0101 in Combination with KEYTRUDA^® Clinical Trial:

In November 2020, our VERSATILE-002 Phase 2 clinical trial evaluating the combination of PDS0101 (Versamune^® plus a mixture of HPV16 antigens) in combination with Merck’s anti-PD-1 therapy, KEYTRUDA^® (pembrolizumab) for first-line treatment of recurrent/ metastatic HPV16-positive head and neck cancer opened and is actively recruiting patients.   The clinical trial will evaluate the efficacy and safety of this therapeutic combination as a first-line treatment in patients with recurrent or metastatic head and neck cancer and high-risk HPV16 infection.

In this sponsored trial, patients whose cancer has returned or spread following initial treatment, will take this combination of two immuno-therapy drugs in lieu of chemotherapy. Enrolling patients with more functional immune systems earlier in disease recurrence that have not been compromised by extensive chemotherapy may allow improved efficacy of the combination.  Patients in the study will receive a total of 5 cycles of combination therapy in the context of standard of care KEYTRUDA™ therapy administered every three weeks until disease progression or intolerance to therapy.

The original study design for this combination trial was restricted to patients naïve to checkpoint inhibitor (CPI) therapy.  PDS amended the protocol in May 2021 to expand this study to include patients with advanced head and neck cancer who have failed multiple treatments, including CPI therapy (CPI refractory patients), a treatment refractory population with extremely high unmet medical need.  The amended study design is a Simon two stage design that will evaluate objective response rate- or ORR – at six months following initiation of treatment in both the original CPI naïve arm and in the expansion CPI refractory arm.  Objective response is measured by radiographic tumor responses according to RECIST 1.1.   There will be a lead-in cohort of 12 patients for the entire study to assess the safety of the combination.  In the CPI naïve arm of the study, the first seventeen (17) patients will be evaluated for efficacy with a minimum of four (4) or more patients with documented objective response required to progress to full enrollment of this arm.  In the expansion CPI refractory arm, the first twenty-one (21) patients will be evaluated for efficacy with a minimum of two (2) or more patients with documented objective response required to progress to full enrollment of this arm.

If the endpoints are achieved, this study may serve as confirmation that PDS0101 enhances the therapeutic benefit of checkpoint inhibitors and could expand evaluation of Versamune®-based therapies in multiple cancer indications.  Total enrollment of both study arms is expected to be approximately ninety-five (95) patients, essentially unchanged from the accrual target of ninety-six (96) patients in the original study design. Preliminary data is expected between the fourth quarter of 2021 and the first quarter of 2022.

PDS0101 in Combination with Bintrafusp alfa (M7824) and NHS-IL12 Clinical Trial:

In June 2020, the first patient was dosed under a PDS0101 Cooperative Research and Development Agreement, which we refer to as the CRADA, in a National Cancer Institute, or NCI, led Phase 2 clinical study evaluating PDS0101, in combination with two investigational immune-modulating agents Bintrafusp alfa (M7824), a bifunctional “trap” fusion protein targeting TGF-β and PD-L1, and NHS-IL12 (M9241), a tumor-targeting immune-cytokine. Bintrafusp alfa is being jointly developed by Merck KGaA, Darmstadt, Germany, and GlaxoSmithKline; NHS-IL12 is being developed by Merck KGaA, Darmstadt, Germany.  The trial is evaluating the treatment combination in both CPI naïve and refractory patients with advanced HPV-associated cancers that have progressed or returned after treatment. Most types of HPV-related cancers (anal, cervical, head and neck, vaginal and vulvar cancers) are represented among the study subjects to date.  Objective response (tumor reduction > 30%) is measured by radiographic tumor responses according to RECIST 1.1.  Full enrollment of a total of 56 patients is expected to be completed between the fourth quarter of 2021 and the first quarter of 2022.

The study was accepted for oral presentation at the 2021 meeting of the American Society of Clinical Oncology (ASCO) held June 4-8, 2021.  On May 20, 2021, we announced the abstract summarizing interim data of 14 patients from the study.  Objective responses were observed in 83% (5 of 6) of HPV16-positive checkpoint inhibitor naïve patients with advanced disease.  The reported objective response rate with current standard of care checkpoint inhibitor treatment is 12-24%.  Objective responses were observed in 63% (5 of 8) of HPV16-positive advanced cancer patients who had also failed checkpoint inhibitor therapy.  The reported objective response rate with current standard of care treatment in CPI refractory patients is even lower at 5-12%.

On June 7, 2021 updated interim data (Abstract 2501) was presented at ASCO by the study’s Principal Investigator Dr. Julius Strauss.  This data included an update on the initial 14 patients with an additional four (4) CPI refractory HPV16-positive patients whose data became available after the abstract submission as well as an additional seven (7) HPV16-negative patients (patients whose cancer was not caused by HPV16 infection) who were not discussed in the abstract.  Tumor reduction and objective response was seen in 83% (5/8) of CPI naïve patients with one (1) achieving a complete response.  After a median of eight (8) months of follow-up, 100% (6/6) of these patients were alive, compared to a historical median survival of 7-11 months. In the CPI refractory arm, tumor reduction was observed in 58% (7/12) patients.  These 12 patients included the initial 8 patients reported in the abstract where 5 of 8, or 63% had tumor reduction.  Of the 4 additional patients in this updated data set, 2 patients already have ongoing tumor reduction but have not yet met the criteria for objective response.  Objective response was achieved in 42% (5/12) patients with one (1) achieving a complete response in this refractory arm.  The objective response rates reported in checkpoint refractory, advanced HPV-cancer patients are lower than those naïve to checkpoint inhibitors, generally only 5-12%.  Importantly, 83% (10/12) of all checkpoint inhibitor refractory patients were still alive at median eight (8) months of follow-up; historic average median survival for this patient population is 3-4 months.  Overall, tumor reduction occurred in 67% (12/18) of CPI naïve and CPI refractory patients who had HPV16-positive cancer.  Of note, in the 7 HPV16-negative patients- those with an HPV type other than HPV16 that do not express the molecular target of PDS0101, zero (0) of seven (7) patients experienced tumor reduction or an objective response, providing insight into the potential role of PDS0101 in the observed activity of the triple combination.  These observations suggest that HPV16-specific CD8+ and CD4+ T-cell induction by PDS0101 as predicted by preclinical studies may promote tumor reduction and enhanced clinical benefit of the triple combination.

Moreover, PDS0101 did not appear to compound the toxicities already reported to be induced by Bintrafusp alfa and NHS-IL12.  This is an important consideration for combination oncology treatment regimens where a key goal is to avoid additional or excess toxicity associated with limited anti-tumor activity.  As would be expected with both PDS0101 and M9241 being delivered subcutaneously, injection site reactions were seen in 20% of patients.  No new or additional toxicities have been observed to date from the addition of PDS0101 to the combination of the other two immunotherapies.

PDS0101 in Combination with Chemo-Radiotherapy Clinical Trial:

In October 2020, a third PDS0101 Phase 2 clinical trial was initiated with The University of Texas MD Anderson Cancer Center and is actively recruiting patients. This clinical trial is investigating the safety and preliminary anti-tumor efficacy of PDS0101 in combination with standard-of-care chemo-radiotherapy, or CRT, and their correlation with critical immunological biomarkers in patients with locally advanced cervical cancer. The study goals include evaluation of the rate of regression in patients with a primary tumor that is greater than or equal to 5cm among approximately thirty-five (35) patients.  The rate of complete response is measured by PET-CT at 6 months and rate of tumor volume reduction evaluated by MRI at 30-40 days from the start of treatment.  Preliminary data is expected from this study in the first half of 2022. We believe that Versamune^®’s strong T-cell induction has the potential to meaningfully enhance efficacy of the current standard of care CRT treatment in this indication.

Other Versamune^® Products Under Development:

PDS0102 – Versamune^® + TARP antigens

The TARP antigen is over-expressed in acute myelogenous leukemia (AML), prostate and breast cancers. In the U.S. 450,000 patients are projected to be diagnosed with prostate or breast cancer this year and 19,900 patients are projected to be diagnosed with AML. One hundred percent of adult and pediatric AML overexpress the TARP tumor antigen while approximately 90% of prostate cancers and 50% of breast cancers overexpress TARP, providing a potentially significant therapeutic opportunity to impact these diseases. In an early human clinical study, the National Cancer Institute demonstrated that its proprietary TARP antigens were  recognized by the immune system in prostate cancer patients with PSA biochemical recurrence leading to a notable reduction in tumor growth rates. In preclinical studies, a dramatically enhanced TARP-specific CD8+ killer T-cell response was observed when our designed TARP antigens were combined with Versamune® (PDS0102). Preclinical development is ongoing.

PDS0103 – Versamune^® + MUC1 antigens

In April 2020, the PDS-NCI CRADA was expanded beyond PDS0101 to include clinical and preclinical development of PDS0103.  PDS0103 is an investigational immunotherapy owned by PDS and designed to treat cancers associated with the mucin-1, or MUC1, oncogenic protein.  PDS0103 combines Versamune^® with novel highly immunogenic agonist epitopes of MUC1 developed by the NCI and licensed by PDS.  MUC1 is highly expressed in multiple solid tumors and has been shown to be associated with drug resistance and poor disease prognosis in breast, colorectal, lung and ovarian cancers, for which PDS0103 is being developed.  In preclinical studies, and similarly to PDS0101 and PDS0102, PDS0103 demonstrated the ability to generate powerful MUC1-specific CD8+ killer T-cells.  PDS0103 is currently in late preclinical development.

PDS0104 – Versamune^® + TRP-2 and melanoma antigens

Rates of melanoma have been rising rapidly over the past few decades and approximately 96,480 new melanomas will be diagnosed this year alone. More than 7,000 of these will prove fatal. PDS0104 combines Versamune ® with various melanoma antigens including the Tyrosinase-related protein 2 (TRP2) antigen which is highly expressed in melanoma. In pre-clinical B16 animal models of aggressive melanoma, PDS0104 has been shown to have unique and significant anti-tumor activity as a monotherapy and has also demonstrated strong anti-tumor synergy in combination with checkpoint inhibitors. As the first approval indications for checkpoint inhibitors occurred in melanoma, there is a growing unmet medical need to identify combination regimens with potential activity in checkpoint inhibitor refractory patients with this disease.  Preclinical development is ongoing.

Infectious Diseases

Our focus remains on developing our oncology products and progressing the clinical trials described above. However we are also developing preventative vaccines to address several infectious diseases. Based on the key characteristics of Versamune^® we are progressing preclinical development of PDS0202, a universal influenza vaccine candidate, which combines Versamune^® with novel influenza vaccine antigens.  PDS0202 pre-clinical development is being supported by an agreement with the National Institute of Allergy and Infectious Diseases Collaborative Influenza Vaccine Innovation Centers, or CIVIC program, with a goal of progressing into a human clinical trial.

PDS0203 is being designed with the goal to potentially provide long-term and broad protection against infection from COVID-19 and its potential mutations, based on the understood potential of Versamune^® to prime the immune system to generate both antibodies for near term protection and T-cell responses for immune memory and long term protection against pathogens.  Farmacore Biotechnology has licensed Versamune^® in Latin America to develop PDS0203 in Brazil.  Farmacore is developing and manufacturing the antigen component of the vaccine, leads all regulatory and clinical trial efforts in Brazil and has selected a top clinical research organization, to conduct clinical trials.

On March 11, 2021, we announced that the COVID-19 vaccine consortium consisting of PDS, Farmacore Biotechnology and Blanver Farmoquímica, received a commitment from the Secretary for Research and Scientific Training of The Ministry of Science, Technology and Innovation of Brazil (“MCTI”) to fund up to approximately US$60 million to support the clinical development and commercialization of a Versamune®-based COVID-19 vaccine in Brazil.  All funding is contingent on the availability of financial resources within the MCTI and subject to negotiations among Farmacore, Blanver and MCTI.  We are monitoring the evolving political and public health situation in Brazil that may pose challenges to developing PDS0203, such as the Brazilian Senate’s vote for compulsory licensing for COVID-19 vaccine technology (legislative process is ongoing).

20

MCTI indicated that it intends to make the funding available to perform a combined Phase 1/2 clinical trial, upon authorization by the Brazilian regulatory agency, Agência Nacional de Vigilância Sanitária (ANVISA) to initiate the proposed clinical program in Brazil.  Additional capital planned to be provided by MCTI will fund the manufacturing process scale up, production and the Phase 3 trial, pending the results of the Phase 1/2 trial. We will contribute scientific expertise and operational support and oversee scale up of the manufacturing process for Phase 3 and commercial production. Blanver Farmoquímica will manufacture, promote, distribute, and commercialize the Versamune®-based COVID-19 vaccine in Latin America. We have not received confirmation of the availability of financial resources within the MCTI to support the clinical development and commercialization of a Versamune®-based COVID-19 vaccine in Brazil; therefore, the clinical development and commercialization of a Versamune®-based COVID-19 vaccine in Brazil has not been initiated. We will be conducting a review of the program with Farmacore to assess progress and next steps.

Our current pipeline of Versamune^®-based therapies is as follows:

Corporate Information

From the Company’s inception, it has devoted substantially all of its efforts to drug development, business planning, engaging regulatory, manufacturing and other technical consultants, acquiring operating assets, planning and executing clinical trials and raising capital.  We currently operate the existing business of Private PDS (as defined below) as a publicly traded company under the name PDS Biotechnology Corporation. We were incorporated as Edge Therapeutics, Inc., or Edge, on January 22, 2009. On March 15, 2019, privately held PDS Biotechnology Corporation, or Private PDS, completed a reverse merger, or the Merger, with Edge, pursuant to which Private PDS survived as a wholly owned subsidiary of Edge. Under the terms of the Merger, Edge changed its name to PDS Biotechnology Corporation and Private PDS changed its name to PDS Biotechnology Corporation.

We have never been profitable and have incurred net losses in each year since inception. Our net losses were $0.6 million, and $3.7 million for the six months ended June 30, 2021 and 2020, respectively. As of June 30, 2021, we had an accumulated deficit of $47.5 million. Substantially all of our net losses have resulted from costs incurred in connection with its research and development programs and from general and administrative costs associated with these operations.

As of June 30, 2021, we had $74.7 million in cash and cash equivalents.

Our future funding requirements will depend on many factors, including the following:

● the timing and costs of our planned clinical trials;

● the timing and costs of our planned preclinical studies of our Versamune® platform;

● the outcome, timing and costs of seeking regulatory approvals;

● the terms and timing of any future collaborations, licensing, consulting or other arrangements that we may enter into;

● the amount and timing of any payments we may be required to make in connection with the licensing, filing, prosecution, maintenance, defense and enforcement of any patents or patent applications or other intellectual property rights; and

● the extent to which we license or acquire other products and technologies.

KEY COMPONENTS OF OUR STATEMENT OF OPERATIONS

Revenue

We have not generated any revenues from commercial product sales and do not expect to generate any such revenue in the near future. We may generate revenue in the future from a combination of research and development payments, license fees and other upfront payments or milestone payments.

Research and Development Expenses

Research and development expenses include employee-related expenses, licensing fees to use certain technology in our research and development projects, costs of acquiring, developing and manufacturing clinical trial materials, as well as fees paid to consultants and various entities that perform certain research and testing on our behalf. Costs for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations or information provided by vendors on their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are reflected in the consolidated financial statements as prepaid or accrued expenses. Costs incurred in connection with research and development activities are expensed as incurred.

We expect that our research and development expenses will increase significantly over the next several years as we advance our Versamune®-based immuno-oncology, or I-O, candidates into and through clinical trials, pursues regulatory approval of our investigational Versamune® candidates and prepare for a possible commercial launch, all of which will also require a significant investment in contract and internal manufacturing and inventory related costs.

The process of conducting human clinical trials necessary to obtain regulatory approval is costly and time consuming. We may never succeed in achieving marketing approval for our injectable I-O candidates. The probability of successful commercialization of our I-O candidates may be affected by numerous factors, including clinical data obtained in future trials, competition, manufacturing capability and commercial viability. As a result, we are unable to determine the duration and completion costs of our research and development projects or when and to what extent we will generate revenue from the commercialization and sale of any of our product candidates.

Research and Development Expenses

Research and development (R&D) expenses increased to $2.8 million for the three months ended June 30, 2021 from $1.4 million for the three months ended June 30, 2020. The increase of $1.3 million in 2021 was primarily attributable to an increase of $0.2 million in personnel costs, $1.0 in clinical studies and $0.1 million in manufacturing.

22

General and Administrative Expenses

General and administrative expenses increased to $2.3 million for the three months ended June 30, 2021 from $1.5 million for the three months ended June 30, 2020. The increase of $0.8 million is primarily attributable to an increase in personnel costs of $0.6 million and an increase in professional services of $0.2 million, which includes legal fees of $0.1 million and consultants of $0.1 million.

Benefit from Income Taxes

Income tax benefit was $4.5 million for the three months ended June 30, 2021 and $0 million for the three months ended June 30, 2020. An increase of $4.5 million was due to the sale of Net Operating Losses (NOL) accumulated through 2019.

Comparison of the Six Months Ended June 30, 2021 and 2020

The following table summarizes the results of our operations for the six months ended June 30, 2021 and 2020:

Research and Development Expenses

Research and development (R&D) expenses increased to $4.2 million for the six months ended June 30, 2021 from $3.4 million for the same period in 2020. The increase of $0.8 million was primarily attributable to an increase in personnel costs of $0.2 million, clinical studies of $1.2 million, offset by decreases in professional consulting of $0.2 million and decrease in manufacturing of $0.4 million.

General and Administrative Expenses

General and administrative expenses increased to $4.0 million for the six months ended June 30, 2021 from $3.6 million for the same period in 2020. The $0.4 million increase was primarily attributable to an increase in personnel costs of $0.8 million, offset by a decrease in professional services of $0.4 million.

Benefit from Income Taxes

Income tax benefit was $4.5 million for the six months ended June 30, 2021 and $0 million for the six months ended June 30, 2020. An increase of $4.5 million was due to the sale of Net Operating Losses (NOL) accumulated through 2019.

23

Liquidity and Capital Resources

On July 29, 2019, we entered into a common stock purchase agreement, or the Aspire Purchase Agreement, with Aspire Capital pursuant to which, we have the right, in our sole discretion, to present Aspire Capital Fund, LLC, or Aspire Capital, with a purchase notice, directing Aspire Capital (as principal) to purchase up to 100,000 shares of our common stock per business day, in an aggregate amount of up to $20.0 million of our common stock, or the Purchased Shares, over the term of the Aspire Purchase Agreement. We may sell an aggregate of 1,034,979 shares of our common stock (which represented 19.99% of our outstanding shares of common stock on the date of the Aspire Purchase Agreement) without stockholder approval. We may sell additional shares of our common stock above the 19.99% limit provided that (i) we obtain stockholder approval or (ii) stockholder approval has not been obtained at any time the 1,034,979 share limitation is reached and at all times thereafter the average price paid for all shares issued under the Aspire Purchase Agreement, is equal to or greater than $5.76, which was the consolidated closing bid price of our common stock on July 26, 2019. The minimum price at which we can sell shares under the Aspire Purchase Agreement is $0.50. On July 29, 2019, we issued 100,654 shares of our common stock to Aspire Capital, as consideration for entering into the Aspire Purchase Agreement, which we refer to as the Commitment Shares. We recorded the fair value of the shares at July 29, 2019 of $603,924 as an expense in the third quarter of 2019. Concurrently with the Aspire Purchase Agreement, we entered into a registration rights agreement with Aspire Capital, or the Registration Rights Agreement. In accordance with the Registration Rights Agreement, on August 20, 2019 we filed a Registration Statement on Form S-1 (File No. 333-232988) to cover the resale of the Commitment Shares and any Purchased Shares issuable to Aspire Capital under the Aspire Purchase Agreement. There is market uncertainty regarding the utilization of financing associated from the Aspire Purchase Agreement. As of September 30, 2020, no Purchase Shares have been sold to Aspire Capital under the Aspire Purchase Agreement.

In February 2020, we completed an underwritten public offering, in which we sold 10,000,000 shares of common stock at a public offering price of $1.30 per share. The shares sold included 769,230 shares issued upon the exercise by the underwriter of its option to purchase additional shares at the public offering price, minus underwriting discounts and commissions. We received gross proceeds of approximately $13 million and net proceeds of approximately $11.9 million after deducting underwriting discounts and commissions. Our operations have also been financed from cash of $29.1 million from the consummation of the Merger in March 2019.

In July, 2020, we filed a shelf registration statement, or the 2020 Shelf Registration Statement, with the SEC, for the issuance of common stock, preferred stock, warrants, rights, debt securities and units, which we refer to collectively as the Shelf Securities, up to an aggregate amount of $100 million. The 2020 Shelf Registration Statement was declared effective on July 31, 2020. On August 13, 2020, we sold 6,900,000 shares of its common stock at a public offering price of $2.75 per share pursuant to the 2020 Shelf Registration Statement, which includes 900,000 shares issued upon the exercise by the underwriter of its option to purchase additional shares at the public offering price, minus underwriting discounts and commissions. We received gross proceeds of approximately $19.0 million and net proceeds of approximately $17.1 million, after deducting underwriting discounts and offering expenses.

In June 2021, we sold 6,088,235 shares of our common stock at a public offering price of $8.50 per share pursuant to the 2020 Shelf Registration Statement, which includes 794,117 shares issued upon the exercise by the underwriter of its option to purchase additional shares at the public offering price, minus underwriting discounts and commissions. We received gross proceeds of approximately $51.7 million and net proceeds of approximately $48.5 million, after deducting underwriting discounts and offering expenses. Approximately $29,300,000 of Shelf Securities remain available for future sale under the 2020 Shelf Registration Statement.

In May 2021 we received approximately $4.5 million from the net sale of tax benefits to an unrelated, profitable New Jersey corporation pursuant the Company’s participation in the New Jersey Technology Business Tax Certificate Transfer Net Operating Loss (NOL) program for State Fiscal Year 2020.

As of June 30, 2021, we had $74.7 million in cash and cash equivalents. Our primary uses of cash are to fund operating expenses, primarily research and development expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable and accrued expenses.

We evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern within one year beyond the filing of this Quarterly Report on Form 10-Q.  Based on such evaluation and our current plans, which are subject to change, management believes that our existing cash and cash equivalents as of June 30, 2021 will be sufficient to satisfy our operating cash needs for at least one year after the filing of this Quarterly Report on Form 10-Q.

We plan to continue to fund our operations and capital funding needs through equity and/or debt financings. However, we cannot be certain that additional financing will be available when needed or that, if available, financing will be obtained on terms favorable to us or our existing stockholders.  We may also enter into government funding programs and consider selectively partnering for clinical development and commercialization. The sale of additional equity would result in additional dilution to our stockholders. Incurring debt financing would result in debt service obligations, and the instruments governing such debt could provide for operating and financing covenants that would restrict our operations. If we are unable to raise additional capital in sufficient amounts or on acceptable terms, we may be required to delay, limit, reduce, or terminate our product development or future commercialization efforts or grant rights to develop and market immunotherapies that we would otherwise prefer to develop and market ourselves. Any of these actions could harm our business, results of operations and prospects.

Cash Flows

The following table shows a summary of our cash flows for each of the periods indicated (in thousands):

	Six Months Ended June 30,
	2021			2020
Net cash used in operating activities	$	(2,856	)	$	(7,268	)
Net cash provided by investing activities		–			–
Net cash provided by financing activities		48,766			12,040
Net increase in cash	$	45,910		$	4,772

Net Cash Used in Operating Activities

Net cash used in operating activities was $2.9 million and $7.3 million for the six months ended June 30, 2021 and 2020, respectively. The decrease in cash used in operating activities of $4.4 million includes the $4.5 million NOL sale. Excluding the NOL sale, net cash used in operating activities increased $0.1 million primarily due to an increase in stock-based compensation of $0.5 million, accounts payables and accruals of $0.7 million offset by an increase in prepaid expenses of $0.7 and a decrease in restructuring reserve of $0.4 million.

Net Cash Provided by Financing Activities

Net cash provided by financing activities for the six months ended June 30, 2021 was due to the receipt of net proceeds from the issuance of common stock of $48.5 million.

Net cash provided by financing activities for the six months ended June 30, 2020 was primarily due to the receipt of net proceeds of $12.0 million due to the issuance of common stock.

Operating Capital Requirements

To date, we have not generated any product revenue. We do not know when, or if, we will generate any product revenue and we do not expect to generate significant product revenue unless and until we obtain regulatory approval and commercialize one of our current or future product candidates. We anticipate that we will continue to generate losses for the foreseeable future, and we expect the losses to increase as we continue the development of, and seek regulatory approvals for, our tablet vaccine candidates, and begin to commercialize any approved vaccine candidates. We are subject to all of the risks incident to the development of new products, and may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may harm our business. We expect to incur additional costs associated with operating as a public company and anticipate that we will need substantial additional funding in connection with our continuing operations.

We evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year beyond the filing of this Quarterly Report.  Our budgeted cash requirements in 2021 and beyond include expenses related to continuing development and clinical studies.  We believe that our existing cash and cash equivalents as of June 30, 2021 are sufficient to continue operations and research and development programs for at least the next 12 months from the date of this Quarterly Report. Until we can generate significant cash from our operations, we expect to continue to fund our operations with available financial resources. These financial resources may not be adequate to sustain our operations.

25

We have based our projections of operating capital requirements on assumptions that may prove to be incorrect and we may use all of our available capital resources sooner than we expect. Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on many factors, including, but not limited to:

● the initiation, progress, timing, costs and results of our planned clinical trials;

● the effects of health epidemics, pandemics, or outbreaks of infectious diseases, including the recent COVID-19 pandemic, on our business operations, financial condition, results of operations and cash flows;

● the outcome, timing and cost of meeting regulatory requirements established by the U.S. Food and Drug Administration, or FDA, the European Medicines Agency, or EMA, and 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 potential intellectual property disputes, including patent infringement actions brought by third parties against us now or in the future;

● the effect of competing technological and market developments;

● the cost of establishing sales, marketing and distribution capabilities in regions where we choose to commercialize our products on our own; and

● the initiation, progress, timing and results of our commercialization of our product candidates, if approved, for commercial sale.

Please see the section titled “Risk Factors” elsewhere in the Quarterly Report and Annual Report for additional risks associated with our operations.

Contractual Obligations and Commitments

The following is a summary of our contractual obligations as of the date indicated:

As of June 30, 2021	Total		Less than One Year		1-3 Years		3-5 Years		More than 5 Years
Operating lease obligations	$	552,977	$	157,663	$	395,314	$	–	$	–
Total contractual obligations	$	552,977	$	157,663	$	395,314	$	–	$	–

Purchase Commitments

We have no material non-cancelable purchase commitments with service providers as we have generally contracted on a cancelable, purchase order basis.

Critical Accounting Polices and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported revenue generated and expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

There have been no material changes to our critical accounting policies and estimates during the six months ended June 30, 2021 from those disclosed in our Annual Report on - Form 10-K for the year ended December 31, 2020.

26

Impact of the CARES Act

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act, or the CARES Act, was enacted and signed into law, and GAAP requires recognition of the tax effects of new legislation during the reporting period that includes the enactment date. The CARES Act, among other things, includes changes to the tax provisions that benefits business entities and makes certain technical corrections to the 2017 Tax Cuts and Jobs Act, including, permitting net operating losses, or NOLs, carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. The CARES Act provides other reliefs and stimulus measures. We have evaluated the impact of the CARES Act, and do not expect that any provision of the CARES Act would result in a material cash benefit to us or have a material impact on our financial statements or internal control over financial reporting.

Operations and Liquidity

While the potential economic impact brought by and over the duration of the COVID-19 pandemic may be difficult to assess or predict, the COVID-19 pandemic has resulted in significant disruption of global financial markets, which could in the future negatively affect our liquidity. In addition, a recession or market volatility resulting from the COVID-19 pandemic could affect our business. We have taken proactive, aggressive action throughout the COVID-19 pandemic to protect the health and safety of our employees and expect to continue to implement these measures until we determine that the COVID-19 pandemic is adequately contained for purposes of our business. We may take further actions as government authorities require or recommend or as we determine to be in the best interests of our employees. Given the nature and type of our short-term investments, we do not believe that the COVID-19 pandemic will have a material impact on our current investment liquidity.

Outlook and Impact of COVID-19 on our Business

In December 2019, a novel (new) coronavirus known as SARS-CoV-2 was first detected in Wuhan, Hubei Province, People’s Republic of China, causing outbreaks of the coronavirus disease, known as COVID-19, that has now spread globally. On January 30, 2020 the World Health Organization (WHO) declared COVID-19 a public health emergency. The Secretary of Health and Human Services declared a public health emergency on January 31, 2020, under section 319 of the Public Health Service Act (42 U.S.C. 247d), in response to the COVID-19 outbreak. On March 11, 2020, the WHO declared COVID-19 a pandemic. The full impact of the COVID-19 pandemic is unknown and rapidly evolving. The COVID-19 pandemic has and could continue to negatively affect the Company’s liquidity and operations. To date, two of the three currently planned PDS0101 clinical trials have been delayed, specifically as a result of the adverse impact the COVID-19 pandemic has had on clinical trial operations for cancer indications in the United States.  Even though both of these studies have since been initiated despite the pandemic challenges, the evolving COVID-19 pandemic has also impacted the pace of enrollment in clinical trials and we may be affected by similar delays as patients may avoid or may not be able to travel to healthcare facilities and physicians’ offices unless due to a health emergency and clinical trial staff can no longer get to the clinic.

Although there is uncertainty related to the anticipated impact of the COVID-19 pandemic on our future results, we believe our current cash reserves, leave us well-positioned to manage our business through this crisis as it continues to unfold. However, the impacts of the COVID-19 pandemic are broad-reaching and continuing and the financial impacts associated with the COVID-19 pandemic are still uncertain.

Despite the economic uncertainty resulting from the COVID-19 pandemic, we intend to continue to focus on the development of our product candidates and we have expanded our infectious disease pipeline since the pandemic brought renewed resources and interest on technologies such as the Versamune® platform in the context of research and development in prevention of COVID-19. We licensed Versamune to Farmacore in Brazil to develop PDS0203; a vaccine for the prevention of COVID-19.  The Secretary for Research and Scientific Training of The Ministry of Science, Technology and Innovation of Brazil provided a commitment to fund up to approximately US$60 million to support the clinical development and commercialization of a Versamune®-based COVID-19 vaccine in Brazil. We have not received confirmation of the availability of financial resources within the MCTI to support the clinical development and commercialization of a Versamune®-based COVID-19 vaccine in Brazil; therefore, the clinical development and commercialization of a Versamune®-based COVID-19 vaccine in Brazil has not been initiated. We will be conducting a review of the program to assess progress and next steps.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.

Smaller Reporting Company

As of January 1, 2021, we are no longer an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. However, we remain a “smaller reporting company,” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended. We will cease to be a smaller reporting company if we have a non-affiliate public float in excess of $250 million and annual revenues in excess of $100 million, or a non-affiliate public float in excess of $700 million, determined on an annual basis. Even though we no longer qualify as an emerging growth company, we may still qualify as a smaller reporting company. As a smaller reporting company, we are permitted and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not smaller reporting companies. We expect to continue to take advantage of some or all of the available exemptions

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The primary objectives of our investment activities are to ensure liquidity and to preserve principal, while at the same time maximizing the income we receive from our cash and marketable securities without significantly increasing risk. As of June 30, 2021, we had cash equivalents of $74.7 million that were held in a non-interest-bearing money operating account and an institutional U.S. Treasury money market fund. Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates. Due to the short-term maturities of our cash equivalents and the low risk profile of our investments, we do not believe that an immediate 100 basis point change in interest rates would have a material effect on the fair market value of our cash equivalents. To minimize the risk in the future, we intend to maintain our portfolio of cash equivalents and short-term investments in institutional market funds that are comprised of U.S. Treasury and Treasury backed repurchase agreements.

ITEM 4: CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

An evaluation was carried out, under the supervision of and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15 (e)) under the Securities Exchange Act of 1934, or the Exchange Act, as of the end of the period covered by this report. Based on the evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures are effective to ensure that the information required to be disclosed by us in the reports we file or submit under the Exchange Act was recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) identified in connection with the evaluation identified above that occurred during the quarter ended June 30, 2021 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

On July 23, 2021, David R. Rosener, a purported stockholder of PDS, filed a putative class action and shareholder derivative complaint in the Court of Chancery of the State of Delaware (C.A. No. 2021-0644) JRS against PDS and all of our directors and certain of our executive officers. The plaintiff named all current directors of PDS as defendants as well as PDS’s Chief Scientific Officer and Chief Medical Officer as defendants and also named PDS as a nominal defendant.  The plaintiff claims that PDS’s bylaws required tabulation of broker non-votes on Proposal 3 of the proxy, which sought shareholder approval of the Second Amended and Restated PDS Biotechnology Corporation 2014 Equity Incentive Plan (the “Restated Plan”) that was voted upon at the 2021 annual stockholder meeting on June 17, 2021.  In addition, the complaint asserts claims for breach of fiduciary duties, declaratory judgment, waste of corporate assets and unjust enrichment in connection with the Restated Plan and the granting of an aggregate award of 1,040,700 stock options to certain executive officers pursuant to the Restated Plan.  The plaintiff seeks unspecified monetary damages, seeks to have the Restated Plan declared void, and seeks recission of the grant of stock options as ultra vires.  Given the early stage of this lawsuit, PDS is unable to reasonably estimate the costs associated with the lawsuit or predict the outcome.  Each of the Company, its directors and the named executives intend to defend this action vigorously.  There can be no guarantee as to the timing of any resolution.

PDS may be involved, from time to time, in legal proceedings and claims arising in the ordinary course of its business. Such matters are subject to many uncertainties and outcomes are not predictable with assurance.

ITEM 1A. RISK FACTORS

There have been no material changes from our risk factors as previously reported in our Annual Report on Form 10-K for the year ended December 31, 2020. However, any investment in our business involves a high degree of risk. Before making an investment decision, you should carefully consider the information we include in this Quarterly Report on Form 10-Q, including our unaudited interim condensed consolidated financial statements and accompanying notes, our Annual Report on Form 10-K for the year ended December 31, 2020 filed on March 18, 2021, including our financial statements and related notes contained therein, and the additional information in the other reports we file with the Securities and Exchange Commission. These risks may result in material harm to our business and our financial condition and results of operations. In this event, the market price of our common stock may decline and you could lose part or all of your investment. Additional risks that we currently believe are immaterial may also impair our business operations. Our business, financial conditions and future prospects and the trading price of our common stock could be harmed as a result of any of these risks.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

There were no unregistered sales of the Company’s equity securities during the six months ended June 30, 2021.

When paired with an antigen, which is a disease-related protein that is recognizable by the immune system, Versamune® has been shown to induce, in vivo, large quantities of high-quality, highly potent polyfunctional CD8+ killer T-cells, a specific sub-type of CD8+ killer T-cell that is more effective at killing infected or target cells. Our immuno-oncology products can potentially be used as a component of combination products with other leading technologies to provide effective treatments across a range of advanced cancer types. We believe our product candidates are of interest for potential treatments in relation to Human Papillomavirus (HPV)-associated cancers, melanoma, colorectal, lung, breast and prostate cancers or as monotherapies in early-stage disease.  PDS is working to progress its infectious disease development program, which includes novel vaccines for COVID-19 and universal influenza.

From the Company’s inception, it has devoted substantially all of its efforts to drug development, business planning, engaging regulatory, manufacturing and other technical consultants, acquiring operating assets, planning and executing clinical trials and raising capital.

In December 2019, a novel (new) coronavirus known as SARS-CoV-2 was first detected in Wuhan, Hubei Province, People’s Republic of China, causing outbreaks of the coronavirus disease, known as COVID-19, that has now spread globally. On January 30, 2020, the World Health Organization (WHO) declared COVID-19 a public health emergency. The Secretary of Health and Human Services declared a public health emergency on January 31, 2020, under section 319 of the Public Health Service Act (42 U.S.C. 247d), in response to the COVID-19 outbreak. On March 11, 2020, the WHO declared COVID-19 a pandemic and on March 13 the President declared a national emergency in response to the pandemic. We continue to learn more about the full impact of the COVID-19 pandemic which has continued to evolve due to the emergence of variants of concern, resulting in new waves of infection regionally and globally. The COVID-19 pandemic has and could continue to negatively affect the Company’s liquidity and operations.  To date, two of the three recently initiated PDS0101 clinical trials were delayed, specifically as a result of the adverse impact the COVID-19 pandemic has had on clinical trial operations for cancer indications in the United States. The FDA issued and has since updated guidance to assist sponsors in assuring the safety of trial participants, maintaining compliance with Good Clinical Practice (GCP) and minimizing risks to trial integrity.  Clinical trial sites have implemented institution-specific measures securing the safety of patients and staff to ensure the integrity of the trials in the face of the ongoing pandemic. All three studies have since been initiated despite the pandemic challenges; however, the evolving COVID-19 pandemic has impacted the pace of enrollment in clinical trials in general and we may be negatively affected with our trials. COVID-19 related travel and other restrictions may also impact the potential for on-site monitoring visiting and audits and inspections by us, third parties, and government regulators. There may be shortages of site personnel and equipment necessary for the timely completion of our trials. We are providing support to address these challenges, but these mitigation measures may not overcome the obstacles that the pandemic has wrought which continue to impede progress of clinical trials.

Although there is uncertainty related to the anticipated impact of the COVID-19 pandemic on our future results, we believe our current cash reserves leave us well-positioned to manage our business through this crisis as it continues to unfold. However, the impacts of the COVID-19 pandemic are broad-reaching and continuing and the financial impacts associated with the COVID-19 pandemic are still uncertain.

Summary of Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 2 – Summary of Significant Accounting Policies

(A) Unaudited interim financial statements:

The interim balance sheet at June 30, 2021, the statements of operations and comprehensive loss and changes in stockholders’ equity for the three and six months ended June 30, 2021 and 2020, and cash flows for the six months ended June 30, 2021 and 2020 are unaudited. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP, in accordance with the requirements of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. GAAP can be condensed or omitted. These condensed consolidated financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments that are necessary for a fair statement of its financial information. The results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the year ending December 31, 2021 or for any other future annual or interim period. The balance sheet as of December 31, 2020 included herein was derived from the audited condensed consolidated financial statements as of that date. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2020, filed by the Company with the SEC in its Annual Report on Form 10-K on March 18, 2021.

(B) Use of estimates:

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of expenses at the date of the consolidated financial statements and during the reporting periods, and to disclose contingent assets and liabilities at the date of the consolidated financial statements. Actual results could differ from those estimates.

(C) Significant risks and uncertainties:

The Company’s operations are subject to a number of factors that may affect its operating results and financial condition. Such factors include, but are not limited to: the clinical and regulatory development of its products, the Company’s ability to preserve its cash resources, the Company’s review of strategic alternatives, the Company’s ability to add product candidates to its pipeline, the Company’s intellectual property, the ability to efficiently and effectively conduct its clinical trials, competition from products manufactured and sold or being developed by other companies, the price of, and demand for, Company products if approved for sale, the Company’s ability to negotiate favorable licensing or other manufacturing and marketing agreements for its products, the Company’s ability to raise capital, and the effects of health epidemics, pandemics, or outbreaks of infectious diseases, including the recent COVID-19 pandemic.

The Company currently has no commercially approved products. As such, there can be no assurance that the Company’s future research and development programs will be successfully commercialized. Developing and commercializing a product requires significant time and capital and is subject to regulatory review and approval as well as competition from other biotechnology and pharmaceutical companies. The Company operates in an environment of rapid change and is dependent upon the continued services of its employees and consultants and obtaining and protecting its intellectual property.

(D) Cash equivalents and concentration of cash balance:

The Company considers all highly liquid securities with a maturity weighted average of less than three months to be cash equivalents. The Company’s cash and cash equivalents in bank deposit accounts, at times, may exceed federally insured limits.

(E) Research and development:

Costs incurred in connection with research and development activities are expensed as incurred. These costs include licensing fees to use certain technology in the Company’s research and development projects as well as fees paid to consultants and entities that perform certain research and testing on behalf of the Company.

Costs for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using data, such as patient enrollment, clinical site activations or information provided by vendors on their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred.

(F) Patent costs:

The Company expenses patent costs as incurred and classifies such costs as general and administrative expenses in the accompanying statements of operations and comprehensive loss.

(G) Stock-based compensation:

The Company accounts for its stock-based compensation in accordance with ASC Topic 718, Compensation—Stock Compensation (“ASC 718”). ASC 718 requires all stock-based payments to employees, directors and non-employees to be recognized as expense in the consolidated statements of operations and comprehensive loss based on their grant date fair values. In order to determine the fair value of stock options on the date of grant, the Company uses the Black-Scholes option-pricing model. Inherent in this model are assumptions related to expected stock-price volatility, option term, risk-free interest rate and dividend yield. While the risk-free interest rate and dividend yield are less subjective assumptions that are based on factual data derived from public sources, the expected stock-price volatility and option term assumptions require a greater level of judgment. The Company expenses the fair value of its stock-based compensation awards to employees and directors on a straight-line basis over the requisite service period, which is generally the vesting period. The Company recognizes forfeitures as they occur.

(H) Net income (loss) per common share:

Basic and diluted net loss per common share is determined by dividing net loss attributable to common stockholders by the weighted average common shares outstanding during the period. For all periods presented, the common shares underlying the preferred stock, common stock options and warrants have been excluded from the calculation because their effect would be anti-dilutive. Therefore, the weighted average shares outstanding used to calculate both basic and diluted loss per common share are the same.

The potentially dilutive securities excluded from the determination of diluted loss per share as their effect is antidilutive, are as follows:

	As of June 30,
	2021		2020
Stock options to purchase Common Stock		3,209,248		1,639,753
Warrants to purchase Common Stock		197,518		197,518
Total		3,406,766		1,837,271

Liquidity [Abstract]

Liquidity

Note 3 – Liquidity

As of June 30, 2021, the Company had $74.7 million of cash and cash equivalents. The Company’s primary uses of cash are to fund operating expenses, primarily research and development expenditures. Cash used to fund operating expenses is impacted by the timing of when the Company pays these expenses, as reflected in the change to the Company’s outstanding accounts payable and accrued expenses.

On July 29, 2019, we entered into a common stock purchase agreement, or the Aspire Purchase Agreement, with Aspire Capital pursuant to which, we have the right, in our sole discretion, to present Aspire Capital Fund, LLC, or Aspire Capital, with a purchase notice, directing Aspire Capital (as principal) to purchase up to 100,000 shares of our common stock per business day, in an aggregate amount of up to $20.0 million of our common stock, or the Purchased Shares, over the term of the Aspire Purchase Agreement. We may sell an aggregate of 1,034,979 shares of our common stock (which represented 19.99% of our outstanding shares of common stock on the date of the Aspire Purchase Agreement) without stockholder approval. We may sell additional shares of our common stock above the 19.99% limit provided that (i) we obtain stockholder approval or (ii) stockholder approval has not been obtained at any time the 1,034,979 share limitation is reached and at all times thereafter the average price paid for all shares issued under the Aspire Purchase Agreement, is equal to or greater than $5.76, which was the consolidated closing bid price of our common stock on July 26, 2019. The minimum price at which we can sell shares under the Aspire Purchase Agreement is $0.50. On July 29, 2019, we issued 100,654 shares of our common stock to Aspire Capital, as consideration for entering into the Aspire Purchase Agreement, which we refer to as the Commitment Shares. We recorded the fair value of the shares at July 29, 2019 of $603,924 as an expense in the third quarter of 2019. Concurrently with the Aspire Purchase Agreement, we entered into a registration rights agreement with Aspire Capital, or the Registration Rights Agreement. In accordance with the Registration Rights Agreement, on August 20, 2019 we filed a Registration Statement on Form S-1 (File No. 333-232988) to cover the resale of the Commitment Shares and any Purchased Shares issuable to Aspire Capital under the Aspire Purchase Agreement. There is market uncertainty regarding the utilization of financing associated from the Aspire Purchase Agreement. As of June 30, 2021, no Purchase Shares have been sold to Aspire Capital under the Aspire Purchase Agreement.

In February 2020, we completed an underwritten public offering, in which we sold 10,000,000 shares of common stock at a public offering price of $1.30 per share. The shares sold included 769,230 shares issued upon the exercise by the underwriter of its option to purchase additional shares at the public offering price, minus underwriting discounts and commissions. We received gross proceeds of approximately $13 million and net proceeds of approximately $11.9 million after deducting underwriting discounts and commissions.

In July 2020, we filed a shelf registration statement, or the 2020 Shelf Registration Statement, with the SEC, for the issuance of common stock, preferred stock, warrants, rights, debt securities and units, which we refer to collectively as the Shelf Securities, up to an aggregate amount of $100 million. The 2020 Shelf Registration Statement was declared effective on July 31, 2020.

In August 2020, the Company sold 6,900,000 shares of its common stock at a public offering price of $2.75 per share pursuant to the 2020 Shelf Registration Statement, which includes 900,000 shares issued upon the exercise by the underwriter of its option to purchase additional shares at the public offering price, minus underwriting discounts and commissions. We received gross proceeds of approximately $19.0 million and net proceeds of approximately $17.1 million, after deducting underwriting discounts and offering expenses.

In May 2021, we received approximately $4.5 million from the net sale of tax benefits to an unrelated, profitable New Jersey corporation pursuant the Company’s participation in the New Jersey Technology Business Tax Certificate Transfer Net Operating Loss (NOL) program for State Fiscal Year 2020.

In June 2021, we completed an underwritten public offering in which we sold 6,088,235 shares of common stock at a public offering price of $8.50 per share pursuant to the 2020 Shelf Registration Statement, which includes 794,117 shares issued upon the exercise by the underwriter of its option to purchase additional shares at the public offering price, minus underwriting discounts and commissions. We received gross proceeds of approximately $51.7 million and net proceeds of approximately $48.5 million, after deducting underwriting discounts and offering expenses. Approximately $29,300,000 of Shelf Securities remain available for future sale under the 2020 Shelf Registration Statement.

Our primary uses of cash are to fund operating expenses, primarily research and development expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable and accrued expenses.

We evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year beyond the filing of this Quarterly Report on Form 10-Q.  Our budgeted cash requirements in 2021 and beyond include expenses related to continuing development and clinical studies.  Based on our available cash resources and cash flow projections as of the date the consolidated financial statements were available for issuance, we believe there are sufficient funds to continue operations and research and development programs for at least 12 months from the date of this report.

We plan to continue to fund our operations and capital funding needs through equity and/or debt financings. However, the Company cannot be certain that additional financing will be available when needed or that, if available, financing will be obtained on terms favorable to the Company or its existing stockholders.  We may also enter into government funding programs and consider selectively partnering for clinical development and commercialization. The sale of additional equity would result in additional dilution to our stockholders. Incurring debt financing would result in debt service obligations, and the instruments governing such debt could provide for operating and financing covenants that would restrict our operations. If we are unable to raise additional capital in sufficient amounts or on acceptable terms, we may be required to delay, limit, reduce, or terminate our product development or future commercialization efforts or grant rights to develop and market immunotherapies that we would otherwise prefer to develop and market ourselves. Any of these actions could harm our business, results of operations and prospects. Failure to obtain adequate financing also may adversely affect our ability to operate as a going concern.

Stock-Based Compensation

Note 7 – Stock-Based Compensation

The Company has three equity compensation plans: the 2009 Stock Option Plan, 2014 Equity Incentive Plan and the 2018 Stock Incentive Plan (the “Plans”).

In 2014, the Company’s stockholders approved the 2014 Equity Incentive Plan pursuant to which the Company may grant up to 91,367 shares as ISOs, NQs and restricted stock units (“RSUs”), subject to increases as hereafter described (the “Plan Limit”). In addition, on January 1, 2015 and each January 1 thereafter and prior to the termination of the 2014 Equity Incentive Plan, pursuant to the terms of the 2014 Equity Incentive Plan, the Plan Limit was and shall be increased by the lesser of (x) 4% of the number of shares of Common Stock outstanding as of the immediately preceding December 31 and (y) such lesser number as the Board of Directors may determine in its discretion. In March 2019, the Plan was amended and restated which removed the annual increase component and was limited to 826,292 shares.

As previously disclosed, on December 8, 2020, the Board of Directors of the Company adopted, subject to stockholder approval, the Second Amended and Restated PDS Biotechnology Corporation 2014 Equity Inventive Plan (the “Restated Plan”), which would amend and restate the Amended and Restated PDS Biotechnology Corporation 2014 Equity Incentive Plan (the “Current Plan”). The Company held its annual meeting of stockholders on June 17, 2021 (the “Annual Meeting”).  The stockholders voted to approve the Restated Plan at the Annual Meeting.  The Restated Plan is identical to the Current Plan in all material respects, except as follows: (a) the number of shares of Common Stock authorized for issuance under the Restated Plan will increase from 826,292 shares to 3,339,243 shares, plus the total number of shares that remained available for issuance, that are not covered by outstanding awards issued under the Current Plan, immediately prior to December 8, 2020; and (b) the Restated Plan will terminate on December 7, 2030, unless earlier terminated. Please reference the disclosure in Note 9 of this Quarterly Report on Form 10-Q for further disclosure regarding the Restated Plan.

In 2018, the Company’s stockholders approved the 2018 Stock Incentive Plan pursuant to which the Company may grant up to 558,071 shares as (i) Stock Options, (ii) Stock Appreciation Rights, (iii) Restricted Stock, (iv) Preferred Stock, (v) Stock Reload Options and/or (vi) Other Stock-Based Awards.

 Pursuant to the terms of the Plans, ISOs have a term of ten years from the date of grant or such shorter term as may be provided in the option agreement. Unless specified otherwise in an individual option agreement, ISOs generally vest over a four year term and NQs generally vest over a  one to five year terms. Unless terminated by the Board, the Plans shall continue to remain effective for a term of ten years or until such time as no further awards may be granted and all awards granted under the Plans are no longer outstanding. As of June 30, 2021, there were 190,799 shares available for grant under the 2018 Stock Incentive Plan.

 On June 17, 2019, the Board adopted the 2019 Inducement Plan (the “Inducement Plan”). The Inducement Plan provides for the grant of non-qualified stock options. The Inducement Plan was recommended for approval by the Compensation Committee of the Board and subsequently approved and adopted by the Board without stockholder approval pursuant to Rule 5635(c)(4) of the Nasdaq Listing Rules.

On December 9, 2020, the Company amended the Inducement Plan solely to increase the total number of shares of Common Stock reserved for issuance under the Inducement Plan from 200,000 shares to 500,000 shares. The 2019 Inducement Plan is administered by the Compensation Committee of the Board. In accordance with Rule 5635(c)(4) of the Nasdaq Listing Rules, non-qualified stock options under the 2019 Inducement Plan may only be made to an employee who has not previously been an employee or member of the Board (or any parent or subsidiary of the Company), or following a bona fide period of non-employment by the Company (or a parent or subsidiary of the Company), if he or she is granted such non-qualified stock options in connection with his or her commencement of employment with the Company or a subsidiary and such grant is an inducement material to his or her entering into employment with the Company or such subsidiary. As of June 30, 2021, there were 223,700 shares available for grant under the 2019 Inducement Plan.

The Company’s stock-based compensation expense related to stock options was recognized in operating expense as follows:

Income Taxes [Abstract]

Income Taxes

Note 8 – Income Taxes

In assessing the realizability of the net deferred tax assets, the Company considers all relevant positive and negative evidence to determine whether it is more likely than not that some portion or all of the deferred income tax assets will not be realized. The realization of the gross deferred tax assets is dependent on several factors, including the generation of sufficient taxable income prior to the expiration of the net operating loss carryforwards. The Company expects to have a loss for 2021 and there will be no current income tax expense. Additionally, there was a full valuation allowance against the net deferred tax assets as of June 30, 2021 and December 31, 2020. In May 2021, in accordance with the State of New Jersey’s Technology Business Tax Certificate Program, which allowed certain high technology and biotechnology companies to sell unused NOL carryforwards to other New Jersey-based corporate taxpayers, the Company sold New Jersey NOL carryforwards, resulting in the recognition of $4.5 million of income tax benefit, net of transaction costs.

The Company’s U.S. statutory rate is 21%. The effective tax rate, excluding the benefit of the sale of any New Jersey net operating losses, for the three and six months ended June 30, 2021 is 0%.  The primary factor impacting the effective tax rate is the anticipated full year operating loss which will require a full valuation allowance against any associate deferred tax asset.

Entities are also required to evaluate, measure, recognize and disclose any uncertain income tax provisions taken on their income tax returns. The Company has analyzed its tax positions and has concluded that as of June 30, 2021, there were no uncertain positions. The Company’s U.S. federal and state net operating losses have occurred since its inception and as such, tax years subject to potential tax examination could apply from that date because the utilization of net operating losses from prior years opens the relevant year to audit by the IRS and/or state taxing authorities. The Company did not have any unrecognized tax benefits and has not accrued any interest or penalties for the three and six months ended June 30, 2021 and for the year ended December 31, 2020.

On July 23, 2021, David R. Rosener, a purported stockholder of PDS, filed a putative class action and shareholder derivative complaint in the Court of Chancery of the State of Delaware (C.A. No. 2021-0644 JRS)  against PDS and all of our directors and certain of our executive officers. The plaintiff named all current directors of PDS as defendants as well as PDS’s Chief Scientific Officer and Chief Medical Officer as defendants and also named PDS as a nominal defendant.  The plaintiff claims that PDS’s bylaws required tabulation of broker non-votes on Proposal 3 of the proxy, which sought shareholder approval of the Second Amended and Restated PDS Biotechnology Corporation 2014 Equity Incentive Plan (the “Restated Plan”) that was voted upon at the 2021 annual stockholder meeting on June 17, 2021.  In addition, the complaint asserts claims for breach of fiduciary duties, declaratory judgment, waste of corporate assets and unjust enrichment in connection with the Restated Plan and the granting of an aggregate award of 1,040,700 stock options to certain executive officers pursuant to the Restated Plan.  The plaintiff seeks unspecified monetary damages, seeks to have the Restated Plan declared void, and seeks recission of the grant of stock options as ultra vires.  Given the early stage of this lawsuit, PDS is unable to reasonably estimate the costs associated with the lawsuit or predict the outcome.  Each of the Company, its directors and the named executives intend to defend this action vigorously.  There can be no guarantee as to the timing of any resolution.

Summary of Significant Accounting Policies [Abstract]

Unaudited Interim Financial Statements

(A) Unaudited interim financial statements:

The interim balance sheet at June 30, 2021, the statements of operations and comprehensive loss and changes in stockholders’ equity for the three and six months ended June 30, 2021 and 2020, and cash flows for the six months ended June 30, 2021 and 2020 are unaudited. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP, in accordance with the requirements of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. GAAP can be condensed or omitted. These condensed consolidated financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments that are necessary for a fair statement of its financial information. The results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the year ending December 31, 2021 or for any other future annual or interim period. The balance sheet as of December 31, 2020 included herein was derived from the audited condensed consolidated financial statements as of that date. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2020, filed by the Company with the SEC in its Annual Report on Form 10-K on March 18, 2021.

Use of Estimates

(B) Use of estimates:

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of expenses at the date of the consolidated financial statements and during the reporting periods, and to disclose contingent assets and liabilities at the date of the consolidated financial statements. Actual results could differ from those estimates.

Significant Risks and Uncertainties

(C) Significant risks and uncertainties:

The Company’s operations are subject to a number of factors that may affect its operating results and financial condition. Such factors include, but are not limited to: the clinical and regulatory development of its products, the Company’s ability to preserve its cash resources, the Company’s review of strategic alternatives, the Company’s ability to add product candidates to its pipeline, the Company’s intellectual property, the ability to efficiently and effectively conduct its clinical trials, competition from products manufactured and sold or being developed by other companies, the price of, and demand for, Company products if approved for sale, the Company’s ability to negotiate favorable licensing or other manufacturing and marketing agreements for its products, the Company’s ability to raise capital, and the effects of health epidemics, pandemics, or outbreaks of infectious diseases, including the recent COVID-19 pandemic.

The Company currently has no commercially approved products. As such, there can be no assurance that the Company’s future research and development programs will be successfully commercialized. Developing and commercializing a product requires significant time and capital and is subject to regulatory review and approval as well as competition from other biotechnology and pharmaceutical companies. The Company operates in an environment of rapid change and is dependent upon the continued services of its employees and consultants and obtaining and protecting its intellectual property.

Cash Equivalents and Concentration of Cash Balance

(D) Cash equivalents and concentration of cash balance:

The Company considers all highly liquid securities with a maturity weighted average of less than three months to be cash equivalents. The Company’s cash and cash equivalents in bank deposit accounts, at times, may exceed federally insured limits.

Research and Development

(E) Research and development:

Costs incurred in connection with research and development activities are expensed as incurred. These costs include licensing fees to use certain technology in the Company’s research and development projects as well as fees paid to consultants and entities that perform certain research and testing on behalf of the Company.

Costs for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using data, such as patient enrollment, clinical site activations or information provided by vendors on their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred.

Patent Costs

(F) Patent costs:

The Company expenses patent costs as incurred and classifies such costs as general and administrative expenses in the accompanying statements of operations and comprehensive loss.

Stock-Based Compensation

(G) Stock-based compensation:

The Company accounts for its stock-based compensation in accordance with ASC Topic 718, Compensation—Stock Compensation (“ASC 718”). ASC 718 requires all stock-based payments to employees, directors and non-employees to be recognized as expense in the consolidated statements of operations and comprehensive loss based on their grant date fair values. In order to determine the fair value of stock options on the date of grant, the Company uses the Black-Scholes option-pricing model. Inherent in this model are assumptions related to expected stock-price volatility, option term, risk-free interest rate and dividend yield. While the risk-free interest rate and dividend yield are less subjective assumptions that are based on factual data derived from public sources, the expected stock-price volatility and option term assumptions require a greater level of judgment. The Company expenses the fair value of its stock-based compensation awards to employees and directors on a straight-line basis over the requisite service period, which is generally the vesting period. The Company recognizes forfeitures as they occur.

Net Income (Loss) per Common Share

(H) Net income (loss) per common share:

Basic and diluted net loss per common share is determined by dividing net loss attributable to common stockholders by the weighted average common shares outstanding during the period. For all periods presented, the common shares underlying the preferred stock, common stock options and warrants have been excluded from the calculation because their effect would be anti-dilutive. Therefore, the weighted average shares outstanding used to calculate both basic and diluted loss per common share are the same.

The potentially dilutive securities excluded from the determination of diluted loss per share as their effect is antidilutive, are as follows:

	As of June 30,
	2021		2020
Stock options to purchase Common Stock		3,209,248		1,639,753
Warrants to purchase Common Stock		197,518		197,518
