Currency Presentation and Currency Translation

Unless otherwise indicated, all references to “dollars,” “$,” “U.S. $” or “U.S. dollars” are to the lawful currency of the United States. All references in this Report to “euro” or “€” are to the currency introduced at the start of the third stage of the European Economic and Monetary Union pursuant to the Treaty establishing the European Community, as amended. We prepare our financial statements in U.S. dollars.

The functional currency for most of our operations is the euro. With respect to our financial statements, the translation from the euro to U.S. Dollars is performed for balance sheet accounts using exchange rates in effect at the balance sheet date and for revenue and expense accounts using a weighted average exchange rate during the period. The resulting translation adjustments are recorded as a component of other comprehensive income.

Where in this Report we refer to amounts in euros, we have for your convenience also in certain cases provided a conversion of those amounts to U.S. Dollars in parentheses. Where the numbers refer to a specific balance sheet account date or financial statement account period, we have used the exchange rate that was used to perform the conversions in connection with the applicable financial statement. In all other instances, unless otherwise indicated, the conversions have been made using the noon buying rate of €1.00 to U.S. $1.11038 based on www.oanda.com as of June 30, 2016.

Forward Looking Statements

This section and other parts of this Quarterly Report on Form 10-Q contains forward looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that involve risks and uncertainties, principally in the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” All statements other than statements of historical fact contained in this Quarterly Report on Form 10-Q, including statements regarding future events, our future financial performance, expectations for growth and revenues, anticipated timing and amounts of milestone and other payments under collaboration agreements, business strategy and plans, objectives of management for future operations, timing and outcome of legal and other proceedings, and our ability to finance our operations are forward-looking statements. We have attempted to identify forward-looking statements by terminology including “anticipates,” “believes,” “can,” “continue,” “ongoing,” “could,” “estimates,” “expects,” “intends,” “may,” “appears,” “future,” “likely,” “plans,” “potential,” “projects,” “predicts,” “should,” “would,” or “will” or the negative of these terms or other comparable terminology. Although we do not make forward-looking statements unless we believe we have a reasonable basis for doing so, we cannot guarantee their accuracy. These statements are only predictions and involve known and unknown risks, uncertainties and other factors, including the risks outlined under “Risk Factors” or elsewhere in our most recent Annual Report on Form 10-K, which may cause our or our industry’s actual results, levels of activity, performance or achievements expressed or implied by these forward-looking statements to differ materially.

Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time and it is not possible for us to predict all risk factors, nor can we address the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause our actual results to differ materially from those contained in any forward-looking statements. Actual results could differ materially from our forward-looking statements due to a number of factors, including, without limitation, risks related to: the results of our research and development activities, including uncertainties relating to the discovery of potential drug candidates and the preclinical and ongoing or planned clinical testing of our drug candidates; the early stage of our drug candidates presently under development; our ability to obtain and, if obtained, maintain regulatory approval of our current drug candidates and any of our other future drug candidates; our need for substantial additional funds in order to continue our operations and the uncertainty of whether we will be able to obtain the funding we need; our future financial performance; our ability to retain or hire key scientific or management personnel; our ability to protect our intellectual property rights that are valuable to our business, including patent and other intellectual property rights; our dependence on third-party manufacturers, suppliers, research organizations, testing laboratories and other potential collaborators; our ability to successfully market and sell our drug candidates in the future as needed; the size and growth of the potential markets for any of our approved drug candidates, and the rate and degree of market acceptance of any of our approved drug candidates; competition in our industry; and regulatory developments in the U.S. and foreign countries.

You should not place undue reliance on any forward-looking statement, each of which applies only as of the date of this Quarterly Report on Form 10-Q. Before you invest in our securities, you should be aware that the occurrence of the events described in Part I, Item 1A (Risk Factors) of our Annual Report on Form 10-K for the year ended December 31, 2015 filed on March 23, 2016 could negatively affect our business, operating results, financial condition and stock price. All forward-looking statements included in this document are based on information available to us on the date hereof, and except as required by law, we undertake no obligation to update or revise publicly any of the forward-looking statements after the date of this Quarterly Report on Form 10-Q to conform our statements to actual results or changed expectations.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. Interim Consolidated Financial Statements

The accompanying unaudited interim condensed consolidated financial statements of Pieris Pharmaceuticals, Inc. (“Pieris” or the “Company”) were prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information. All significant intercompany balances and transactions have been eliminated in the consolidation. Certain information and footnotes normally included in financial statement prepared in accordance with U.S. GAAP have been omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete annual consolidated financial statements. It is recommended that these financial statements be read in conjunction with the consolidated financial statements and related footnotes that appear in the Annual Report on Form 10-K of the Company for the year ended December 31, 2015 filed with the SEC on March 23, 2016 (the “2015 Annual Report”).

In the opinion of management, the unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited condensed consolidated financial statements for the year ending December 31, 2015, and all adjustments, including normal recurring adjustments, considered necessary for the fair presentation of the Company’s unaudited interim consolidated financial statements have been included. The results of operations for the six months ended June 30, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016 or any future period.

Use of estimates

The preparation of the condensed consolidated financial statements in accordance with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the reported amounts of revenues and expenses in the financial statements and disclosures in the accompanying notes. Significant estimates are used for, but are not limited to, revenue recognition, deferred tax assets, liabilities and valuation allowances, fair value of stock options and various accruals. Management evaluates its estimates on an ongoing basis. Actual results and outcomes could differ materially from management’s estimates, judgments and assumptions.

2. Critical Accounting Policies

Research and development expenses

Research and development expenses are charged to the statement of operations as incurred. Research and development expenses are comprised of costs incurred in performing research and development activities, including salaries and benefits, facilities costs, pre-clinical and clinical costs, contract services, consulting, depreciation and amortization expense, and other related costs. Costs associated with acquired technology, in the form of upfront fees or milestone payments, are charged to research and development expense as incurred.

3. Revenues

General

Pieris, to date has not generated revenues from product sales. Pieris has generated revenues pursuant to (i) license and collaboration agreements, which include upfront payments for licenses or options to obtain licenses, payments for research and development services and milestone payments, and (ii) government grants.

Multiple element arrangements, such as license and development arrangements are analyzed to determine whether the deliverables, which often include a license and performance obligations such as research and steering committee services, can be separated or whether they must be accounted for as a single unit of accounting in accordance with generally accepted accounting principles, or U.S. GAAP. The Company recognizes up-front license payments as revenue upon delivery of the license only if the license has stand-alone value. If the license is considered to not have stand-alone value, the arrangement would then be accounted for as a single unit of accounting and the license payments and payments for performance obligations are recognized as revenue over the estimated period of when the performance obligations are performed.

If the Company is involved in a steering committee as part of a multiple element arrangement, the Company assesses whether its involvement constitutes a performance obligation or a right to participate. Steering committee services that are determined to be performance obligations are combined with other research services or performance obligations required under an arrangement, if any, in determining the level of effort required in an arrangement and the period over which the Company expects to complete its aggregate performance obligations.

Whenever the Company determines that an arrangement should be accounted for as a single unit of accounting, it must determine the period over which the performance obligations will be performed and revenue will be recognized. Revenue will be recognized using either a relative performance or straight-line method. The Company recognizes revenue using the relative performance method provided that the Company can reasonably estimate the level of effort required to complete its performance obligations under an arrangement and such performance obligations are provided on a best-efforts basis. Full-time equivalents are typically used as the measure of performance.

If the Company cannot reasonably estimate when its performance obligation either ceases or becomes inconsequential and perfunctory, then revenue is deferred until the Company can reasonably estimate when the performance obligation ceases or becomes inconsequential. Revenue is then recognized over the remaining estimated period of performance.

Significant management judgment is required in determining the level of effort required under an arrangement and the period over which the Company is expected to complete its performance obligations under an arrangement.

F.Hoffmann-La Roche Ltd. and Hoffmann- La Roche Inc.

In December 2015, the Company entered into a Research Collaboration and License Agreement (the “Roche Agreement”) with F.Hoffmann- La Roche Ltd. and Hoffmann- La Roche Inc., (“Roche”), for the research, development and commercialization of Anticalin-based drug candidates against a predefined, undisclosed target in cancer immune therapy. The parties will jointly pursue a preclinical research program with respect to the identification and generation of Anticalins that bind to a specific target for an expected period of 20 months, which may be extended by Roche for up to an additional 12 months. Roche has the ability to continue exclusivity rights for up to an additional 5 years. Both Roche and the Company will participate in a joint research committee in connection with this agreement. Following the research program, Roche will be responsible for subsequent pre-clinical and clinical development of any product developed through the research plan and will have worldwide commercialization rights to any such product.

Roche has paid $6.5 million of an upfront payment for the research collaboration. Additionally, Roche will pay Pieris for research services provided by Pieris in conjunction with the research program. Roche will also pay Pieris for certain milestones relating to development, regulatory and sales milestones as they are achieved.

Pieris recorded $1.1 million and $2.3 million in revenue for the three and six months ended June 30, 2016, respectively, related to the recognition of the upfront Roche payment during those periods. Revenue recognized is associated with the portion of the research services performed during the periods as well as the value of research services provided by Pieris in connection with the ongoing research program. No revenues were recorded for the three and six months ended June 30, 2015.

The Company identified the research and commercial licenses, performance of R&D services, and participation in the joint research committee as deliverables under the Roche Agreement. For revenue recognition purposes, management has determined that there are two units of accounting at the inception of the agreement representing (i) the research and commercial licenses and the performance of R&D services which do not have standalone value, and (ii) the participation in the joint research committee.

In addition to the upfront payment, under the Roche Agreement, the Company is eligible to receive research funding, development and regulatory, and sales based milestone payments up to approximately $416.8 million, plus royalties on future sales of any commercial products. The total potential milestones are categorized as follows: development and regulatory milestones—$289.2 million; and sales milestones—$122.6 million. Management has determined that the development milestones are not substantive because they do not relate solely to past performance of the Company and that the Company’s involvement in the achievement is limited to progress reports and other updates. Non-substantive milestones will be recognized when achieved to the extent the Company has no remaining performance obligations under the arrangement.

4. Net Loss per Common Share

Basic net loss per share was determined by dividing net loss by the weighted average common shares outstanding during the period. Diluted net loss per share was determined by dividing net loss by diluted weighted average shares outstanding. Diluted weighted average shares reflect the dilutive effect, if any, of common stock options based on the treasury stock method.

For all financial statement periods presented the number of basic and diluted weighted average shares outstanding was the same because any increase in the number of shares of common stock equivalents for any period presented would be antidilutive based on the net loss for the period.

For the six months ended June 30, 2016 and 2015, approximately 5.9 million and 0.9 million weighted average shares subject to stock options and warrants, respectively, as calculated using the treasury stock method, were excluded from the calculation of diluted weighted average common shares outstanding as their effect would have been antidilutive.

5. Fair Value Measurement

ASC Topic 820 Fair Value Measurement defines fair value as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at the measurement date. Pieris applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. The standard describes the following fair value hierarchy based on three levels of input, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

Level 1 inputs are quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 utilizes quoted market prices in markets that are not active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency.

Level 3 inputs are unobservable inputs for the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date.

For the periods presented in these interim financial statements Pieris has no cash equivalents and debt instruments as of each balance sheet date presented.

All of other current assets and current liabilities on our consolidated balance sheets approximate their respective carrying amounts.

6. Related-Party Transactions

Research and License Agreement with Technische Universität München (“TUM”)

On July 4, 2003, the Company entered into a research and licensing agreement with TUM, which was subsequently renewed and, on July 26, 2007, superseded and replaced. The agreement established a joint research effort led by Prof. Arne Skerra, Chair of Biological Chemistry of TUM, to optimize Anticalin technologies for use in therapeutic, prophylactic and diagnostic applications and as research reagents, and to gain fundamental insights in lipocalin scaffolds. Prof. Dr. Skerra was a member of the Company´s supervisory board when the parties entered into such agreement and during the period covered by the consolidated financial statements in this report. The Company provided certain funding for TUM research efforts performed under the agreement.

As a result of research efforts to date under the agreement, the Company holds a worldwide exclusive license under its license agreement with TUM to multiple patents and patent applications, including an exclusive license to an issued U.S. patent, which patent will expire in 2027 (subject to a possible term adjustment period). The Company also holds an exclusive license to an issued U.S. patent No. 8,420,051, which patent is expected to expire in 2029. The Company bears the costs of filing, prosecution and maintenance of patents assigned or licensed to the Company under the agreement.

As consideration for the assigned patents and licenses above, the Company is required to pay certain development milestones to TUM. The Company also is obliged to pay low-single-digit royalties, including annual minimum royalties, on sales of such products incorporating patented technologies. If the Company grants licenses or sublicenses to those patents to third parties, the Company will be obliged to pay a percentage of the resulting revenue to TUM. The Company’s payment obligations are reduced by the Company’s proportionate contribution to a joint invention. Payment obligations terminate on expiration or annulment of the last patent covered by the agreement. The Company can terminate the licenses to any or all licensed patents upon specified advance notice to TUM. TUM may terminate the license provisions of the agreement only for cause. Termination of the agreement does not terminate the rights in patents assigned to the Company.

Effective as of the fourth quarter of 2015, Pieris no longer deems TUM a related party due to Prof. Dr. Skerra no longer having a supervisory board position in Pieris GmbH or other direct relationship with the Company since its initial public offering in December 2014. Therefore no expenses to TUM as a related party were incurred during the three and six months ended June 30, 2016. The Company incurred expenses related to TUM as a related party of approximately $14,000 and $28,000 for the three and six months ended June 30, 2015.

Consulting Contract between Prof. Dr. Arne Skerra and Pieris AG

In 2001, the Company entered into a Consulting Agreement with Prof. Dr. Arne Skerra, pursuant to which Prof. Dr. Arne Skerra provides advice regarding the use of new proteins, in particular Anticalin proteins and antibodies, for the purpose of research and development. As of the fourth quarter of 2015, Pieris no longer deems Prof. Dr. Skerra a related party due to Prof. Dr. Skerra no longer having a supervisory board position in Pieris GmbH or other direct relationship with the Company after its initial public offering in December 2014. Therefore no expenses to Prof. Dr. Skerra as a related party were incurred during the three and six months ended June 30, 2016. The Company incurred and paid to Prof. Dr. Skerra consulting fees of approximately $6,000 and $11,000 for the three and six months ended June 30, 2015.

7. Accrued expenses

The Company has recorded the following accrued expenses as of June 30, 2016 and December 31, 2015, respectively:

8. Stock-based compensation

2014 Stock Plan

Pieris granted 88,853 and 1,157,734 options to employees, consultants, and directors under its 2014 Employee, Director and Consultant Equity Incentive Plan, (the “2014 Plan”) during the three and six months ended June 30, 2016, respectively. Pieris granted 72,235 and 25,000 options to employees, consultants, and directors under the 2014 Employee, Director and Consultant Equity Incentive Plan, (the “Plan”) during the three and six months ended June 30, 2015, respectively.

The 2014 Plan was terminated on June 28, 2016 when the Company adopted its 2016 Employee, Director and Consultant Equity Incentive Plan, (the “2016 Plan”).

2016 Stock Plan

In June 2016, the Company adopted the 2016 Plan which provides for the grant of stock options, restricted and unrestricted stock awards and other stock-based awards to employees of the Company, non-employee directors of the Company and certain other consultants performing services for the Company as designated by the Compensation Committee of the Board of Directors or the Board of Directors.

At June 30, 2016, the number of common shares reserved for issuance under the 2016 Plan was 3,750,000. The vesting periods of equity incentives issued under the 2016 Plan are determined by the Compensation Committee of the Company’s Board of Directors, with stock options generally vesting over a four-year period. In September 2015, a stock option to purchase 450,000 shares of the Company’s common stock, par value $0.001 (the “Common Stock”) was granted to a newly–hired executive officer subject to certain restrictions on exercise that required the Company’s shareholders to approve an increase in the number of shares authorized under the 2014 Plan. Upon the Company’s adoption of the 2016 Plan, this stock option was amended and issued under the 2016 Plan and the total shares available under the 2016 Plan reflect the issuance of this option. No stock options were granted under the 2016 Plan during the three and six months ended June 30, 2015. As of June 30, 2016, there were 3,305,000 shares available for future grant under the 2016 Plan.

Stock-based compensation expense for the three and six months ended June 30, 2016 was $0.6 million and $1.0 million, respectively, and was $0.3 million and $0.5 million for the three and six-months ended June 30, 2015, respectively.

Total stock-based compensation expense was recorded to operating expenses based upon the functional responsibilities of the individuals holding the respective options as follows:


	Three months ended June 30,				Six months ended June 30,
	2016		2015		2016		2015
Research and Development	$	175,498	$	78,348	$	301,939	$	129,185
General and administrative		436,347		189,691		678,290		356,189

Total stock-option expense	$	611,845	$	268,039	$	980,229	$	485,374

There were no options exercised during the three and six months ended June 30, 2016 and 2015, respectively.

The Company uses the Black-Scholes option pricing model to determine the estimated fair value for stock-based awards. Option-pricing models require the input of various subjective assumptions, including the option’s expected life, expected dividend yield, price volatility, risk free interest rate and forfeitures of the underlying stock. Accordingly, the weighted-average fair value of the options granted during the three and six months ended June 30, 2016 was $1.09 and $1.01, respectively. The weighted-average fair value of the options granted during the three and six months ended June 30, 2015 was $1.81 and $1.82, respectively. The calculation was based on the following assumptions:


	Three months ended June 30,				Six months ended June 30,
	2016		2015		2016		2015
Dividend yield		0.0%		0.0%		0.0%		0.0%
Expected volatility		75.12% - 75.53%		73.43% - 75.07%		75.12% - 76.00%		73.43% - 75.07%
Weighted average risk-free interest rate		1.13% - 1.49%		1.49% - 1.79%		1.13% - 1.61%		1.49% - 1.79%
Expected term		5.0 - 5.7 years		5.3 - 5.8 years		5.0 - 5.7 years		5.3 - 5.8 years

Option-pricing models require the input of various subjective assumptions, including the option´s expected life and the price volatility of the underlying stock. Pieris’ estimated expected stock price volatility is based on the average volatilities of other guideline companies in the same industry. Pieris’ expected term of options granted during the three and six months ended June 30, 2016 and 2015, respectively was derived using the SEC’s simplified method. The risk-free rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

The Company’s stock options have a maximum term of ten years from the date of grant. Stock options granted under the 2016 Plan may be either incentive stock options (“ISOs”), or nonqualified stock options. The exercise price of stock options granted under the 2016 Plan must be at least equal to the fair market value of the common stock on the date of grant. The Company’s general policy is to issue common shares upon the exercise of stock options.

9. Consulting Shares

In March 2015, the Company entered into an independent consulting agreement (the “Consulting Agreement”) with the Del Mar Consulting Group, Inc. and Alex Partners, LLC (the “Consultants”), pursuant to which the Company issued 150,000 shares of common stock, to the Consultants (the “Consulting Shares”). The Company agreed to retain the Consultants to provide investor relations consulting to the Company for a period commencing on March 6, 2015 (the “Commencement Date”) and ending thirteen months after the Commencement Date (such period, the “Term”). The shares issued in connection with the Consulting Agreement were deemed to be exempt from registration in reliance upon Section 4(a)(2) of the Securities Act as a transaction by an issuer not involving any public offering.

The Company recognized expenses in connection with the issuance of the Consulting Shares of $0.1 million and $0.4 million for the three and six months ended June 30, 2015 in general and administrative expenses. No expenses were recognized during the 2016 period as the remaining shares vested on September 2, 2015 and the remaining expense was recorded based on the fair value of the shares on that date.

10. Private Placement

In June 2016, the Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) for a private placement of the Company’s securities with a select group of institutional investors (the “2016 PIPE”). The 2016 PIPE sale transaction, by the Company, consisted of 8,188,804 units at a price of $2.015 per unit for gross proceeds, to the Company, of approximately $16.5 million. After deducting for placement agent fees and offering expenses, the aggregate net proceeds from the private placement was approximately $15.3 million.

Each unit consisted of (i) one share of the Company’s Common Stock or non-voting series A convertible preferred stock (the “Series A Convertible Preferred Stock”) which are convertible into one share of common stock, (ii) one warrant to purchase 0.4 shares of Common Stock at an exercise price of $2.00 per share and (iii) one warrant to purchase 0.2 shares of Common Stock at an exercise price of $3.00 per share . The warrants will be exercisable for a period of five years from the date of issuance. Each share of Series A Convertible Preferred Stock was issued at a price of $2.015 per share, and is convertible into 1,000 shares of common stock, provided the holder and/or its affiliates do not own greater than 9.99% of the total number of Pieris common stock then outstanding. The Series A Convertible Preferred Stock has no registration or voting rights. In event of a true liquidation or winding down of the business, holders of Series A Convertible Preferred Stock will be paid prior to the holders of Common Stock. In connection with the 2016 PIPE, the Company issued 3,225,804 shares of Common Stock and 4,963 shares of Series A Convertible Preferred Stock to the 2016 PIPE investors.

The Company expects to use the proceeds from the 2016 PIPE towards further development and pre-clinical and clinical work of the Company´s proprietary Anticalin ^® product portfolio, including the lead candidates as well as the development of other programs and product candidates, and general corporate purposes.

As a result of the 2016 PIPE the number of common stock outstanding increased by 3,225,804 shares and the number of Series A Convertible Preferred Stock outstanding increased by 4,963 shares for the three and six months ended June 30, 2016.

11. License and Transfer Agreement

On April 18, 2016 the Company entered into a license and transfer agreement (the “Original Agreement”) with Enumeral Biomedical Holdings, Inc. (“Enumeral”), pursuant to which the Company acquired a non-exclusive worldwide license to use specified patent rights and know-how owned by Enumeral to research, develop and market fusion protein. As contemplated by the terms of the Original Agreement, the Company entered into a definitive license and transfer agreement (the “Definitive Agreement”) with Enumeral on June 6, 2016, to expand the scope of the Company’s option to license additional antibodies from Enumeral. Under the Definitive Agreement, Enumeral has granted Pieris options to license two additional undisclosed Enumeral antibodies (each, a “Subsequent Option”). The Subsequent Options expire on May 31, 2017. If Pieris licenses an additional antibody pursuant to a Subsequent Option, Pieris must pay to Enumeral an additional undisclosed option exercise payment, and any resulting fusion protein products will be subject to royalties and development and sales milestones in the same amounts applicable to the fusion proteins consisting of an Enumeral’s PD-1 antibody linked to one or more Anticalin ^® proteins.

Under the terms of the Original Agreement, the Company agreed to pay Enumeral an upfront license fee of $250,000 upon signing in April 2016 and subsequently elected to pay a $750,000 maintenance fee in May 2016. The terms of the Definitive Agreement, were essentially unchanged from the Original Agreement, the Company has agreed to pay Enumeral development milestones up to an aggregate of $37.8 million and sales milestones up to an aggregate of $67.5 million. Consistent with the terms of the Original Agreement, the Company also agreed to pay Enumeral royalties within a range in the low to lower-middle single digits as a percentage of net sales depending on the amount of net sales in the applicable years. In the event that the Company is required to pay a license fee or royalty to any third party related to the licensed products, the royalty payment due to Enumeral shall be reduced by the amount of such third party fees or payments, up to 50% of the royalty payment for each calendar year due to Enumeral.

The term of the Definitive Agreement ends upon the expiration of the last to expire patent covered under the license. The Definitive Agreement may be terminated by the Company on 30 days’ notice and by Enumeral upon 60 days’ notice of a material breach by the Company (or 30 days with respect to a breach of payment obligations by the Company), provided that the Company has not cured such breach and dispute resolution procedures specified in the Agreement have been followed. The Agreement will also automatically terminate if the Company fails to make the maintenance fee payment described above.

All amounts paid related to the Agreement have been expensed as research and development expense as incurred. The Company incurred $1.0 million for the three and six months ended June 30, 2016.

12. Recent Accounting Pronouncements

In August 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-15, “Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern” which is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. Substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its financial obligations as they become due within one year after the date that the financial statements are issued (or are available to be issued). ASU No. 2014-15 provides guidance to an organization’s management, with principles and definitions intended to reduce diversity in the timing and content of disclosures commonly provided by organizations in the footnotes of their financial statements. ASU No. 2014-15 is effective for annual reporting periods ending after December 15, 2016, and for annual and interim periods thereafter. Early adoption is permitted. Had this standard been adopted as of June 30, 2016, the Company does not believe it would have been required to make any additional disclosures.

In February 2016, the FASB issued ASU No. 2016-02, “ Leases (Topic 842) ”. Under the amendments in ASU 2016-02 lessees will be required to recognize (i) a lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term for all leases (with the exception of short-term leases) at the commencement date. This guidance is effective for fiscal years beginning after December 15, 2019 including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the potential impact the adoption of this standard will have on its financial statements and related disclosures.

In March 2016, the FASB issued ASU No. 2016-08, “Revenues from Contract with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” . The amendments are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations by amending certain existing illustrative examples and adding additional illustrative examples to assist in the application of the guidance. This guidance is effective for fiscal years beginning after December 15, 2018 including interim periods within those fiscal years. The Company is currently evaluating the potential impact the adoption of this standard will have on its financial statements and related disclosures.

In March 2016, the FASB issued ASU No. 2016-09, “Compensation – Stock Compensation (Topic 718): Improvement to Employee Share-Based Payment Accounting”. Under the amendments in ASU 2016-09 several aspects of the accounting for share-based payment award transactions are simplified, including (i) income tax consequences, (ii) classification of awards as either equity or liabilities and (iii) classification on the statement of cash flows. This guidance is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any interim or annual period. The Company is currently evaluating the potential impact the adoption of this standard will have on its financial statements and related disclosures.

In April 2016, the FASB issued ASU. No. 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing” . The amendments in ASU 2016-10 add further guidance on identifying performance obligations and also to improve the operability and understandability of the licensing implementation guidance. The amendments do not change the core principle of the guidance in Topic 606. This guidance is effective for annual periods beginning after December 15, 2018, including interim reporting periods therein. The Company is currently evaluating the potential impact the adoption of this standard will have on its financial statements and related disclosures.

In May 2016, the FASB issued ASU No. 2016-12, “Revenue from Contracts with Customer (Topic 606): Narrow-Scope Improvements and Practical Expedients”. The amendments in ASU 2016-12 address narrow-scope improvements to the guidance on collectability, noncash consideration, and completed contracts at transition. Additionally, the amendments in this update provide a practical expedient for contract modifications at transition and an accounting policy election related to the presentation of sales taxes and other similar taxes collected from customers. This guidance is effective for annual periods beginning after December 15, 2018, including interim reporting periods therein. The Company is currently evaluating the potential impact the adoption of this standard will have on its financial statements and related disclosures.

Pieris has considered other recent accounting pronouncements and concluded that they are either not applicable to the business, or that the effect is not expected to be material to the unaudited condensed consolidated financial statements as a result of future adoption.

13. Subsequent Events

On July 25, 2016, the Board of Directors of the Company, following the recommendation of the Nominating and Corporate Governance Committee of the Board, elected Julian Adams, Ph.D., President of Research & Development of Infinity Pharmaceuticals, Inc., to the Company’s Board to serve as a Class I Director of the Company with a term expiring at the 2018 annual meeting of stockholders.

Company Overview

We are a clinical-stage biopharmaceutical company that discovers and develops Anticalin ^® protein-based drugs to target validated disease pathways in a unique and transformative way. Our pipeline includes immune-oncology multi-specifics tailored for the tumor micro-environment, an inhaled Anticalin to treat uncontrolled asthma and a half-life-optimized Anticalin to treat anemia. Proprietary to Pieris, Anticalin proteins are a novel class of low molecular-weight therapeutic proteins derived from lipocalins, which are naturally occurring low-molecular weight human proteins typically found in blood plasma and other bodily fluids.

Each of our development programs focus on the following:

•

300-Series oncology drug candidates are multispecific Anticalin ^® -based proteins designed to engage immunomodulatory targets and consist of a variety of multifunctional biotherapeutics that genetically link two distinct Anticalin proteins together or an antibody with one or more Anticalin proteins, thereby constituting a multispecific protein;

•

PRS-343 our lead immune-oncology program is a 4-1BB/HER2 bispecific, comprised of a HER2-targeting antibody genetically linked to a 4-1BB-targeting Anticalin, in which tumor-targeted drug clustering mediated by HER2 expressed on certain solid tumors is intended to drive tumor localized T cell activation for patient unresponsive to current standard of care. PRS-343 is currently in IND enabling studies and we expect to initiate a Phase 1 clinical trial in the first half of 2017; and

•

PRS-342 is a 4-1BB/GPC3 bispecific comprised of a GPC3-targeting Anticalin genetically linked via an antibody Fc domain to a 4-1BB-targeting Anticalin, in which tumor-targeted drug clustering mediated by GPC3 expressed on certain solid tumors is intended to drive tumor-localized T cell activation for patients unresponsive to current standard of care. PRS-342 is currently in preclinical studies; and

•

PRS-332 our lead dual checkpoint antagonist program, defines a series of fusion proteins, each of which comprises a PD-1 targeting antibody genetically linked to an Anticalin that engages an undisclosed immune checkpoint. We expect to nominate a bispecific development candidate and initiate IND enabling studies for that candidate by the end of 2016; and

•

PRS-080 is an Anticalin protein that binds to hepcidin, a natural regulator of iron in the blood. It has been designed to target hepcidin for the treatment of functional iron deficiency in anemic patients with chronic kidney disease particularly in end-stage renal disease patients requiring dialysis; and

•

PRS-060 is a drug candidate that binds to the IL-4RA receptor, thereby inhibiting the signaling of IL-4 and IL-13, two cytokines (small proteins mediating signaling between cells within the human body) known to be key mediators in the inflammatory cascade that causes asthma and other inflammatory diseases.

Our programs are in varying stages:

•

300-Series—We are conducting activities relating to lead candidate identification, lead candidate optimization, preclinical evaluation and IND filing preparation on several of our 300-Series lead candidates. For our lead candidate, PRS-343we expect to complete IND enabling studies in 2017 and plan a Phase I clinical study to begin in the first half of 2017;

•

PRS-080—We completed a Phase Ia single-ascending dose clinical trial with PRS-080 in healthy volunteers in 2015. Based on the data obtained we are now continuing further development of PRS-080 in a Ib clinical study in CKD5 patients requiring hemodialysis and which we expect to complete by the end of 2016, which we expect will be followed by a multi-dose trial in the same patient population in 2017; and

•

PRS-060—We have formulated PRS-060 for pulmonary delivery by inhalation, and we are currently manufacturing bulk drug substance for GLP inhalation toxicology studies and for the manufacture of Drug Product for clinical studies. We intend to begin a Phase I clinical trial with this program in mid-2017.

Our core Anticalin ^® technology and platform was developed in Germany, and we have partnership arrangements with major multi-national pharmaceutical companies headquartered in the U.S., Europe and Japan and with regional pharmaceutical companies headquartered in India. These include existing agreements with Daiichi Sankyo Company Limited, (“Daiichi Sankyo”), and Sanofi Group, (“Sanofi”), pursuant to which our Anticalin platform has consistently achieved its development milestones. Furthermore, we established a collaboration with F.Hoffman – La Roche Ltd. and Hoffmann – La Roche Inc., (“Roche”) in December 2015. We have discovery and preclinical collaboration and service agreements with both academic institutions and private firms in Australia.

Since inception, we have devoted nearly all of our efforts and resources to our research and development activities. We have incurred significant net losses since inception. For the three and six months ended June 30, 2016 we reported a net loss of $5.9 million and $10.0 million, respectively. For the three and six months ended June 30, 2015 we reported a net loss of $3.5 million and $7.2 million, respectively. As of June 30, 2016, we had an accumulated deficit of $89.9 million.

We expect to continue incurring substantial losses for the next several years as we continue to develop our clinical and preclinical drug candidates and programs. Our operating expenses are comprised of research and development expenses and general and administrative expenses.

We have not generated any revenues from product sales to date, and we do not expect to generate revenues from product sales for at least the next several years. Our revenues for the periods presented were primarily from license and collaboration agreements with our partners, and, to a lesser extent, from grants from government agencies.

A significant portion of our operations are conducted in countries other than the United States. Since we conduct our business in U.S. dollars, our main exposure, if any, results from changes in the exchange rates between the euro and the U.S. dollar. All assets and liabilities denominated in euros are translated into U.S. dollars at the exchange rate on the balance sheet date. Revenues and expenses are translated at the average rate during the period. Equity transactions are translated using historical exchange rates. Adjustments resulting from translating foreign currency financial statements into U.S. dollars are included in accumulated other comprehensive loss. We may incur negative foreign currency translation changes as a result of changes in currency exchange rates.

Financial Operations Overview

The following discussion summarizes the key factors our management believes are necessary for an understanding of our consolidated financial statements.

Revenues

We have not generated any revenues from product sales to date, and we do not expect to generate revenues from product sales for the foreseeable future. Our revenues for the last two years have been primarily from the license and collaboration agreements with Sanofi, Daiichi Sankyo, Roche and, to a much lesser extent, grants from government agencies.

The revenues from Sanofi, Daiichi Sankyo and Roche have been comprised primarily of upfront payments, research and development services and, to a lesser extent, milestone payments. We recognized revenues from upfront payments under these agreements based on multiple-element arrangement guidance as we have determined that the licenses to which the payments related did not have standalone value. Research service revenue is recognized when the costs are incurred and the services have been performed. Revenue from milestone payments is recognized when all of the following conditions are met: (1) the milestone payments are non-refundable, (2) the probability of the achievement of the milestone is near certain , (3) substantive effort on our part is involved in achieving the milestone, (4) the amount of the milestone payment is reasonable in relation to the effort expended or the risk associated with achievement of the milestone, and (5) a reasonable amount of time passes between the up-front license payment and the first milestone payment.

We expect our revenues for the next several years to consist of upfront payments, research funding and milestone payments from strategic collaborations we currently have or may establish in the future.

Research and Development Expenses

The process of researching and developing drugs for human use is lengthy, unpredictable and subject to many risks. We expect to continue incurring substantial expenses for the next several years as we continue to develop our clinical and preclinical drug candidates and programs. We are unable with any certainty to estimate either the costs or the timelines in which those costs will be incurred. Our current development plans focus on three lead drug programs: PRS-080, PRS-060 and 300-series. These programs consume a large proportion of our current, as well as projected, resources.

Our research and development costs include costs that are directly attributable to the creation of certain of our Anticalin ^® drug candidates and are comprised of:

•

internal recurring costs, such as labor and fringe benefits, materials and supplies, facilities and maintenance costs; and

•

fees paid to external parties who provide us with contract services, consulting services, such as preclinical testing, manufacturing and related testing, and clinical trial activities.

General and Administrative Expenses

General and administrative expenses consist primarily of payroll, employee benefits, equity compensation, and other personnel-related costs associated with executive, administrative and other support staff. Other significant general and administrative expenses include the costs associated with professional fees for accounting, auditing, insurance costs, consulting, and legal services.

•

The $0.7 million increase in revenues from upfront payments in the three months ended June 30, 2016 compared to the three months ended June 30, 2015 relates to the recognition of an upfront payment under our collaboration with Roche, which commenced in January 2016 . The revenue for the upfront payment is recorded based on the proportionate performance method using the full-time equivalents as a measure to spread the upfront payment over the research term. No upfront payments were recognized for the three months ended June 30, 2015.

•

The $0.4 million increase in revenues from research and development services in the three months ended June 30, 2016 compared to the three months ended June 30, 2015 mainly relates to research and development services being provided to Roche pursuant to the Roche Agreement. No research and development services were recognized for the three months ended June 30, 2015.

The decrease in revenues from grants in the three months ended June 30, 2016 compared to the three months ended June 30, 2015 results from the end of the Seventh Research Framework Program (“FP7”) under which the Company recognized $0.2 million in the three months ended June 30, 2015. No grant revenues were recognized for the three months ended June 30, 2016 as the Company received the last tranche under the FP7 program in November 2015 and no other programs under which the Company could receive government grants are currently in place. The following table provides a comparison of revenues for the six months ended June 30, 2016 and 2015, respectively (in thousands):


	Six months ended June 30, 2016		Six months ended June 30, 2015		$ Change			% Change

•

The $1.5 million increase in revenues from upfront payments in the six months ended June 30, 2016 compared to the six months ended June 30, 2015 relates to the recognition of an upfront payment under our collaboration with Roche, which commenced in January 2016 . The revenue for the upfront payment is recorded based on the proportionate performance method using the full-time equivalents as a measure to spread the upfront payment over the research term. No upfront payments were recognized for the six months ended June 30, 2015.

The $0.8 million increase in revenues from research and development services in the six months ended June 30, 2016 compared to the six months ended June 30, 2015 mainly relates to research and development services being provided to Roche pursuant to the Roche Agreement. No research and development services were recognized for the six months ended June 30, 2015.

•

The decrease in revenues from grants in the six months ended June 30, 2016 compared to the six months ended June 30, 2015 resulted from the end of the Seventh Research Framework Program, or FP7, under which the Company recognized $0.4 million in the six months ended June 30, 2015. No grant revenues were recognized for the six months ended June 30, 2016 as the Company received the last tranche under the FP7 program in November 2015 and no other programs under which the Company could receive government grants are currently in place.

Research and Development

The following table provides a comparison of the research and development expenses for our drug candidates and projects for the three months ended June 30, 2016 and 2015, respectively (in thousands):


	Three months ended June 30, 2016		Three months ended June 30, 2015		$-Change			%-Change
PRS-060	$	566	$	—	$	566			100	%
PRS-080		223		641		(418	)		(187	%)
PRS-300 series		1,084		540		544			50	%
Other R&D activities		2,627		545		2,082			382	%

Total	$	4,500	$	1,726	$	2,774			161	%

Total research and development expenses were $4.5 million for the three months ended June 30, 2016 as compared to $1.7 million for the three months ended June 30, 2015.

The $2.8 million increase in total research and development expenses in the three months ended June 30, 2016 compared to the three months ended June 30, 2015 is primarily due to:

•

increased chemistry, manufacturing and controls (“CMC”) and other preclinical costs associated with PRS-060, as we carry out IND enabling studies;

•

increased preclinical and CMC costs for PRS-343 as we carry out our IND enabling studies and development costs for other 300 -Series programs ;

•

offset by decreased expenses for PRS-080, as the Phase Ia trial has been completed and Phase Ib trial has recently started; and

•

increase in other R&D activities of $2.1 million. This increase is due to a $0.6 million increase in personnel-related expenses, including stock-based compensation expense due to the hiring of additional R&D staff, as well as an increase of $1.0 million for license fees related to Enumeral. General lab supplies increased by $0.1 million, consulting costs by $0.2 million and travel costs and other costs by $0.2 million.

The following table provides a comparison of the research and development expenses for the six months ended June 30, 2016 and 2015, respectively (in thousands):


	Six months ended June 30, 2016		Six months ended June 30, 2015		$-Change			%-Change
PRS-060	$	906	$	22	$	884			98	%
PRS-080		572		1,254		(682	)		(119	%)
PRS-300 series		2,177		969		1,208			55	%
Other R&D activities		4,505		1,005		3,500			348	%

Total	$	8,160	$	3,250	$	4,910			151	%

Total research and development expenses were $8.2 million for the six months ended June 30, 2016 as compared to $3.3 million for the six months ended June 30, 2015.

The $4.9 million increase in total research and development expenses in the six months ended June 30, 2016 compared to the three months ended June 30, 2015 is primarily due to:

•

increased chemistry, manufacturing and controls (“CMC”) and other preclinical costs associated with PRS-060, as we carry out IND enabling studies;

•

increased preclinical and CMC costs for PRS-343 as we carry out our IND enabling studies and development costs for other PRS-300-Series programs;

•

offset by decreased expenses for PRS-080, as the Phase Ia trial has been completed and Phase Ib has recently begun; and

•

increase in other R&D activities of $3.5 million. This increase is due to a $1.3 million increase in personnel-related expenses, including stock-based compensation expense due to the hiring of additional R&D staff, as well as an increase in license fees related to TUM and Enumeral of $1.3 million. General lab supplies increased $0.2 million as well as travel and consulting costs of $0.4 million and various facility and other costs of $0.3 million.

As of June 30, 2016, we employed 31 full-time employees and 2 consultants in our research and development group compared to 29 full-time and 5 part-time employees in our research and development group as of June 30, 2015.

General and Administrative

General and administrative expenses were $2.4 million for the three months ended June 30, 2016 compared to $2.0 million for the three months ended June 30, 2015. The increase of $0.4 million resulted primarily from an increase of $0.4 million in higher personnel related costs, including an increase in stock compensation expense due to the hiring of additional G&A staff and $0.1 million in transaction expenses related to Enumeral license and trans2fer agreement. These amounts are offset by $0.1 million in lower legal and other costs.

General and administrative expenses were $4.3 million for the six months ended June 30, 2016 compared to $4.4 million for the six months ended June 30, 2015. General and administrative expenses decreased due to $0.7 million of lower legal, consulting and other costs offset by higher personnel related costs of $0.4 million, including an increase in stock compensation expense due to the hiring of additional G&A staff and increased transaction and investor relation expenses of $0.2 million.

Non-operating income (expenses), net

Non-operating other expenses increased to $0.1 million in the three months ended June 30, 2016 from a gain of approximately $4,000 of non-operating income for the three months ended June 30, 2015. This increase is mainly a result of net foreign currency transaction losses related to the weakness of the Euro against the U.S. dollar at the end of the second quarter of 2016.

Non-operating income increased to $0.1 million in the six months ended June 30, 2016 from approximately $1,000 of non-operating income for the six months ended June 30, 2015. This increase is mainly a result of net foreign currency transaction gains related to the strengthening of the Euro against the U.S. dollar in the periods presented.

Liquidity and Capital Resources

Through June 30, 2016, we have funded our operations with $192.3 million of cash that we obtained from the following main sources: $118.0 million from sales of equity; $6.5 million from loans; $14.2 million from grants from government agencies; and $53.6 million in total payments received under license and collaboration agreements, including $12.6 million for research and development services costs we received from our collaboration partners. We expect that reimbursements of our development costs by Daiichi Sankyo and Sanofi will decline going forward, and we do not expect such reimbursements to be a significant source of funding in the future.

As of June 30, 2016, we had a total of $40.4 million in cash.

We have experienced operating losses since our inception and had a total accumulated deficit of $89.9 million as of June 30, 2016. We expect to incur additional costs and will require additional capital. We have incurred losses in nearly every period since inception including the three and six months ended June 30, 2016. These losses have primarily resulted in significant cash used in operations. Due to the upfront payment received from Roche during the six months ended June 30, 2016 offset with our net losses for the period, our cash used in operating activities was $3.9 million. During the six months ended June 30, 2015, our cash used in operations was $6.7 million. We have several research and development programs underway in varying stages of development and we expect they will continue to consume increasing amounts of cash for development, conducting clinical trials and the testing and manufacturing of product material. As we continue to conduct these activities necessary to pursue FDA approval of our 300-Series, including PRS-343, PRS- 342 and PRS-332, and PRS-080 and PRS-060 and our other product candidates, we expect the cash needed to fund operations to increase significantly over the next several years.

On July 6, 2015 we closed a public offering of an aggregate of 9,090,909 shares of our common stock, par value $0.001 per share, or the Common Stock, at a purchase price of $2.75 per share. On July 28, 2015 the underwriters exercised their option to purchase an additional 1,211,827 shares of common stock at the public offering price of $2.75 per share. Gross proceeds from the offering, including the over-allotment option, were $28.3 million and net proceeds were approximately $25.8 million.

In June 2016, we entered into a securities purchase agreement for a private placement with a select group of institutional investors. The private placement, referred to as the 2016 PIPE, consisted of the sale of 8,188,804 units at a price of $2.015 per unit for gross proceeds to us of approximately $16.5 million. After deducting for placement agent fees and offering expenses, the aggregate net proceeds from the 2016 PIPE was approximately $15.3 million.

Each unit consisted of (i) one share of common stock or non-voting series A convertible preferred stock, par value $0.001 per share, or the series A preferred shares, which are convertible into one share of common stock, (ii) one warrant to purchase 0.4 shares of common stock at an exercise price of $2.00 per share, and (iii) one warrant to purchase 0.2 shares of common stock at an exercise price of $3.00 per share. The 2016 PIPE transaction closed on June 8, 2016.

We will need to obtain additional funding in order to continue our operations and pursue our business plans. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce, or eliminate our research and development programs or future commercialization efforts.

We expect that our existing cash and cash equivalents will enable us to fund our operations and capital expenditure requirements for at least the next twelve months. Our requirements for additional capital will depend on many factors, including the following:

•

the scope, rate of progress, results, timing and cost of our clinical studies, preclinical testing and other related activities;

•

the cost of manufacturing clinical supplies, and establishing commercial supplies, of our drug candidates and any products that we may develop;

•

the number and characteristics of drug candidates that we pursue;

•

the cost, timing and outcomes of regulatory approvals;

•

the cost and timing of establishing sales, marketing and distribution capabilities;

•

the terms and timing of any collaborative, licensing and other arrangements that we may establish;

•

the timing, receipt and amount of sales, profit sharing or royalties, if any, from our potential products;

•

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

•

the extent to which we acquire or invest in businesses, products or technologies, although we currently have no commitments or agreements relating to any of these types of transactions.

We cannot be sure that future funding will be available to us on acceptable terms, or adequate enough at all. Due to often volatile nature of the financial markets, equity and debt financing may be difficult to obtain. In addition, any unfavorable development or delay in the progress for our 300-Series programs, including PRS-343, PRS-342 and PRS-332, and PRS-080 and PRS-060 could have a material adverse impact on our ability to raise additional capital.

We may seek to raise any necessary additional capital through a combination of private or public equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other marketing and distribution arrangements. To the extent that we raise additional capital through marketing and distribution arrangements or other collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our drug candidates, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. If we raise additional capital through private or public equity offerings, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Critical Accounting Policies and Estimates

Refer to Part II, Item 7, “Critical Accounting Policies and Estimates” of our Annual Report on Form 10-K for the fiscal year ended on December 31, 2015 for a discussion of our critical accounting policies and estimates. There were no significant changes to our Critical Accounting Policies and Estimates in the six months ended June 30, 2016.

Recently Issued Accounting Pronouncements

We review new accounting standards to determine the expected financial impact, if any, that the adoption of each such standard will have. For the recently issued accounting standards that we believe may have an impact on our consolidated financial statements, see “Note12—Recently Issued Accounting Pronouncements” in our consolidated financial statements.

Emerging Growth Company and Smaller Reporting Company Status

The Jumpstart Our Business Startups Act of 2012, or the JOBS Act, establishes a class of company called an “emerging growth company,” which generally is a company whose initial public offering was completed after December 8, 2011 and had total annual gross revenues of less than $1 billion during its most recently completed fiscal year. Additionally, Section 12b-2 of the Exchange Act establishes a class of company called a “smaller reporting company,” which generally is a company with a public float of less than $75 million as of the last business day of its most recently completed second fiscal quarter or, if such public float is $0, had annual revenues of less than $50 million during the most recently completed fiscal year for which audited financial statements are available. We currently qualify as both an emerging growth company and a smaller reporting company.

As an emerging growth company and a smaller reporting company, we are eligible to take advantage of certain exemptions from various reporting requirements that are not available to public reporting companies that do not qualify for those classifications, including without limitation the following:

•

An emerging growth company is exempt from any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and financial statements, commonly known as an “auditor discussion and analysis.”

•

An emerging growth company is not required to hold a nonbinding advisory stockholder vote on executive compensation or any golden parachute payments not previously approved by stockholders.

•

Neither an emerging growth company nor a smaller reporting company is required to comply with the requirement of auditor attestation of management’s assessment of internal control over financial reporting, which is required for other public reporting companies by Section 404 of the Sarbanes-Oxley Act.

•

A company that is either an emerging growth company or a smaller reporting company is eligible for reduced disclosure obligations regarding executive compensation in its periodic and annual reports, including without limitation exemption from the requirement to provide a compensation discussion and analysis describing compensation practices and procedures.

•

A company that is either an emerging growth company or a smaller reporting company is eligible for reduced financial statement disclosure in registration statements, which must include two years of audited financial statements rather than the three years of audited financial statements that are required for other public reporting companies. Smaller reporting companies are also eligible to provide such reduced financial statement disclosure in annual reports on Form 10-K.

For as long as we continue to be an emerging growth company and/or a smaller reporting company, we expect that we will take advantage of the reduced disclosure obligations available to us as a result of those respective classifications. We will remain an emerging growth company until the earlier of (i) December 31, 2019, the last day of the fiscal year following the fifth anniversary of the date of the first sale of our common stock pursuant to an effective registration statement under the Securities Act; (ii) the last day of the fiscal year in which we have total annual gross revenues of $1 billion or more; (iii) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under applicable SEC rules. We expect that we will remain an emerging growth company for the foreseeable future, but cannot retain our emerging growth company status indefinitely and will no longer qualify as an emerging growth company on or before December 31, 2019. We will remain a smaller reporting company until we have a public float of $75 million or more as of the last business day of our most recently completed second fiscal quarter, and we could retain our smaller reporting company status indefinitely depending on the size of our public float.

Emerging growth companies may elect to take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to take advantage of the benefits of this extended transition period. Our financial statements may therefore not be comparable to those of companies that comply with such new or revised accounting standards.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Not applicable.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining “disclosure controls and procedures”, as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, as well as for establishing and maintaining “adequate internal control over financial reporting” as such term is defined in Rule 13a-15(f) under the Exchange Act. The Company’s system of internal controls over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements in accordance with generally accepted accounting principles.

Because of the inherent limitations surrounding internal controls over financial reporting, our disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Our management, under the supervision of and with the participation of the Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of the Company’s internal control over financial reporting and disclosure controls and procedures as of June 30, 2016. In making this assessment, management used the updated criteria set forth in 2013 by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework.

Based on our assessment under the COSO Internal Control-Integrated Framework, management believes that, as of June 30, 2016, our internal control over financial reporting was not effective, as described below.

A material weakness is a deficiency, or a combination of deficiencies, in internal controls over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim consolidated financial statements would not be prevented or detected on a timely basis.

In connection with the preparation of our financial statements for the three and six months ended June 30, 2016, we concluded that we had a material weakness relating to the technical accounting for complex transactions. During the period we noted an error in the accounting for our equity transaction. The error was corrected in the financial statements prior to their issuance. We have developed and implemented a remediation plan for this material weakness. We will continue to execute our remediation plan, which includes, among other things, engagement of additional technical expertise, as needed, on complex accounting matters to support the accounting and finance team and the internal control environment.

Notwithstanding this material weakness, we have concluded that the financial statements and other financial information included in this Quarterly Report on Form 10-Q, fairly present in all material respects our financial condition, results of operations and cash flows as of, and for, the periods presented.

Changes in Internal Control over Financial Reporting

Except for material weakness described above, there were no changes in our internal control over financial reporting identified in connection with the evaluation of such internal control required by Rules 13a-15(d) and 15d-15(d) under the Exchange Act that occurred during the quarter ended June 30, 2016 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

Claims and lawsuits are filed against our Company from time to time. Although the results of pending claims are always uncertain, we believe that we have adequate reserves or adequate “insurance coverage” in respect of these claims, but no assurance can be given as to the sufficiency of such reserves or insurance coverage in the event of any unfavorable outcome resulting from these actions.

Item 1A. Risk Factors

There have been no material changes from the risk factors previously disclosed in Part I, Item 1A (Risk Factors) of our Annual Report on Form 10-K for the fiscal year ended December 31, 2015.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

On June 8, 2016, we entered into a securities purchase agreement for a private placement with a select group of institutional investors. The private placement, which we refer to as the 2016 PIPE, consisted of the sale of 8,188,804 units at a price of $2.015 per unit for gross proceeds to us of approximately $16.5 million. After deducting for placement agent fees and offering expenses, the aggregate net proceeds from the 2016 PIPE was approximately $15.3 million.

Each unit consisted of (i) one share of our common stock, par value $0.001 per share, or the Common Stock, or one share of our non-voting series A convertible preferred stock, par value $0.001 per share, or the Series A Preferred Shares, which are convertible into one share of Common Stock, (ii) one warrant to purchase 0.4 shares of Common Stock at an exercise price of $2.00 per share, and (iii) one warrant to purchase 0.2 shares of Common Stock at an exercise price of $3.00 per share. The 2016 PIPE closed on June 8, 2016.

The sale and issuance of the securities set forth above were deemed to be exempt from registration under the Securities Act of 1933, as amended, or the Securities Act, by virtue of Section 4(2) or Rule 506 promulgated under Regulation D promulgated thereunder. Each of the recipients of securities in these transactions was an accredited investor within the meaning of Rule 501 of Regulation D under the Securities Act and had adequate access, through employment, business or other relationships, to information about us. No underwriters were involved in these transactions.

Item 3. Defaults Upon Senior Securities

CERTIFICATE OF DESIGNATION OF

SERIES A CONVERTIBLE PREFERRED STOCK

PIERIS PHARMACEUTICALS, INC.

Pieris Pharmaceuticals, Inc., a Nevada corporation (the “ Corporation ”), in accordance with the provisions of Nevada Revised Statutes (“ NRS ”) 78.195 and 78.1955, does hereby certify that, pursuant to the authority conferred upon the board of directors of the Corporation (the “ Board of Directors ”) by the Corporation’s articles of incorporation, as heretofore amended to date (the “ Articles of Incorporation ”), the Board of Directors has, by a resolution duly adopted pursuant thereto, established a series of the Corporation’s preferred stock consisting of four thousand nine hundred sixty three (4,963) shares of the Corporation’s preferred stock, par value $0.001 per share, designated as “Series A Convertible Preferred Stock” and having the voting powers, designations, preferences, privileges, limitations, restrictions and relative rights set forth as follows, in addition to any provisions of the Articles of Incorporation applicable to all classes and series of Preferred Stock (all capitalized terms used but not defined herein shall have the meanings set forth in the Articles of Incorporation):

a.

Each share of Series A Preferred Stock shall have a par value of $0.001 per share.

b. The Corporation shall register shares of the Series A Preferred Stock in the name of the Holders thereof from time to time upon records to be maintained by the Corporation for that purpose (the “ Series A Preferred Stock Register ”). The Series A Preferred Stock shall be issued in book entry only, provided that the Corporation shall issue one or more certificates representing shares of Series A Preferred Stock, to the extent such issuance is requested by a given Holder. References herein to certificates representing the Series A Preferred Stock shall apply only if such shares have been issued in certificated form. The Corporation may deem and treat the registered Holder of shares of Series A Preferred Stock as the absolute owner thereof for the purpose of any conversion thereof and for all other purposes. The Corporation shall register the transfer of any shares of Series A Preferred Stock in the Series A Preferred Stock Register, upon surrender of the certificates evidencing such shares to be transferred, duly endorsed by the Holder thereof, to the Corporation at its address specified herein. Upon any such registration or transfer, a new certificate evidencing the shares of Series A Preferred Stock so transferred shall be issued to the transferee (if requested) and a new certificate evidencing the remaining portion of the shares not so transferred, if any, shall be issued to the transferring Holder, in each case, within three Business Days. The provisions of this Certificate of Designation are intended to be for the benefit of all Holders from time to time and shall be enforceable by any such Holder.

Section 3. Dividends . Holders be entitled to receive when, as and if dividends are declared and paid on the Corporation’s Common Stock, an equivalent dividend (with the same dividend declaration date and payment date), calculated on an as-converted basis. Other than the foregoing, the Holders of Series A Preferred Stock shall not be entitled to receive any dividends in respect of the Series A Preferred Stock, unless and until specifically declared by the Board of Directors of the Corporation to be payable to the Holders of the Series A Preferred Stock.

Section 4. Voting Rights . Except as otherwise provided herein or as otherwise required by the NRS, the Series A Preferred Stock shall have no voting rights. However, as long as any shares of Series A Preferred Stock are outstanding, the Corporation shall not, without the affirmative vote of the Holders of a majority of the then outstanding shares of the Series A Preferred Stock, (a) alter or change adversely the powers, preferences or rights given to the Series A Preferred Stock or alter or amend this Certificate of Designation, (b) increase the number of authorized shares of Series A Preferred Stock, or (c) enter into any agreement with respect to any of the foregoing.

Section 5. Rank; Liquidation .

a. The Series A Preferred Stock shall rank (i) senior to the Common Stock, and (ii) senior to any class or series of capital stock of the Corporation hereafter created specifically ranking by its terms junior to any Series A Preferred Stock (“ Junior Securities ”); (iii) on parity with any class or series of capital stock of the Corporation hereafter created specifically ranking by its terms on parity with the Series A Preferred Stock (“ Parity Securities ”); and (iv) junior to any class or series of capital stock of the Corporation hereafter created specifically ranking by its terms senior to any Series A Preferred Stock (“ Senior Securities ”), in each case, as to distributions of assets upon liquidation, dissolution or winding up of the Corporation, whether voluntarily or involuntarily.

b. Subject to the prior and superior rights of the holders of any Senior Securities of the Corporation, upon liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, each Holder shall be entitled to receive, in preference to any distributions of any of the assets or surplus funds of the Corporation to the holders of the Common Stock and Junior Securities and pari passu with any distribution to the holders of Parity Securities, an amount equal to $0.001 per share of Series A Preferred Stock, plus an additional amount equal to any dividends declared but unpaid on such shares, before any payments shall be made or any assets distributed to holders of any class of Common Stock or Junior Securities. If, upon any such liquidation, dissolution or winding up of the Corporation, the assets of the Corporation shall be insufficient to pay the holders of shares of the Series A Preferred Stock the amount required under the preceding sentence, then all remaining assets of the Corporation shall be distributed ratably to holders of the shares of the Series A Preferred Stock and Parity Securities.

Section 6. Conversion .

a. Conversions at Option of Holder . Each share of Series A Preferred Stock shall be convertible, at any time and from time to time from and after the Issuance Date, at the option of the Holder thereof, into a number of shares of Common Stock equal to the Conversion Ratio. Holders shall effect conversions by providing the Corporation with the form of conversion notice attached hereto as Annex A (a “ Notice of Conversion ”), duly completed and executed. Other than a conversion following a Fundamental Transaction or following a notice provided for under Section 7(d)(ii) hereof, the Notice of Conversion must specify at least a number of shares of Series A Preferred Stock to be converted equal to the lesser of (x) 100 shares (such number subject to appropriate adjustment following the occurrence of an event specified in Section 7(a) hereof) and (y) the number of shares of Series A Preferred Stock then held by the

Holder. Provided the Corporation’s transfer agent is participating in the Depository Trust Company (“ DTC ”) Fast Automated Securities Transfer program, the Notice of Conversion may specify, at the Holder’s election, whether the applicable Conversion Shares shall be credited to the account of the Holder’s prime broker with DTC through its Deposit Withdrawal Agent Commission system (a “ DWAC Delivery ”). The “ Conversion Date ”, or the date on which a conversion shall be deemed effective, is defined as the Trading Day that the Notice of Conversion, completed and executed, is sent by facsimile to, and received during regular business hours by, the Corporation; provided that if such shares of Series A Preferred Stock were issued in certificated form, then the original certificate(s) representing such shares of Series A Preferred Stock being converted, duly endorsed, and the accompanying Notice of Conversion, are received by the Corporation within two Trading Days thereafter. In all other cases, the Conversion Date shall be defined as the Trading Day on which the original certificates (if any) representing the shares of Series A Preferred Stock being converted, duly endorsed, and the accompanying Notice of Conversion, are received by the Corporation. The calculations set forth in the Notice of Conversion shall control in the absence of manifest or mathematical error.

b. Conversion Ratio . The “ Conversion Ratio ” for each share of Series A Preferred Stock shall be equal to the Stated Value divided by the Conversion Price.

c. Beneficial Ownership Limitation . Notwithstanding anything in this Certificate of Designation to the contrary, the Corporation shall not effect any conversion of the Series A Preferred Stock, and a Holder shall not have the right to convert any portion of the Series A Preferred Stock, to the extent that, after giving effect to an attempted conversion set forth on an applicable Notice of Conversion, such Holder (together with such Holder’s Affiliates, and any other Person whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act and the applicable regulations of the Commission, including any “group” of which the Holder is a member) would beneficially own a number of shares of Common Stock in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder and its Affiliates shall include the number of shares of Common Stock issuable upon conversion of the Series A Preferred Stock subject to the Notice of Conversion with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (A) conversion of the remaining, unconverted Series A Preferred Stock beneficially owned by such Holder or any of its Affiliates, and (B) exercise or conversion of the unexercised or unconverted portion of any other securities of the Corporation (including any warrants) beneficially owned by such Holder or any of its Affiliates that are subject to a limitation on conversion or exercise similar to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this Section 6(c), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the applicable regulations of the Commission. In addition, for purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and the applicable regulations of the Commission. For purposes of this Section 6(c), it is understood that the number of shares of Common Stock beneficially owned by each Holder shall be aggregated with each other Holder for purposes of Section 13(d) of the Exchange Act. For purposes of this Section 6(c), in determining the number of outstanding shares of Common Stock, absent actual knowledge of such Holder to the contrary, a Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (A) the Corporation’s most recent periodic or

annual filing with the Commission, as the case may be, (B) a more recent public announcement by the Corporation that is filed with the Commission, or (C) a more recent notice by the Corporation or the Corporation’s transfer agent to the Holder setting forth the number of shares of Common Stock then outstanding. Upon the written request of a Holder (which may be by email), the Corporation shall, within three Trading Days thereof, confirm in writing to such Holder (which may be via email) the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to any actual conversion or exercise of securities of the Corporation, including shares of Series A Preferred Stock, by such Holder or its Affiliates since the date as of which such number of outstanding shares of Common Stock was last publicly reported or confirmed to the Holder. The initial “ Beneficial Ownership Limitation ” shall be 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock pursuant to such Notice of Conversion (to the extent permitted pursuant to this Section 6(c)). By written notice to the Corporation, which will not be effective until the 61st day after such notice is delivered to the Corporation, a Holder may increase or decrease the Beneficial Ownership Limitation applicable solely to such Holder to such other percentage limit as may be determined by the Holder, not to exceed 19.99%, provided that any increase in the Beneficial Ownership Limitation shall not be effective until the 61st day after such notice is delivered to the Corporation. The Corporation shall be entitled to rely on representations made to it by the Holder in any Notice of Conversion regarding its Beneficial Ownership Limitation.

d. Mechanics of Conversion

i. Delivery of Certificate or Electronic Issuance Upon Conversion . Not later than three Trading Days after the applicable Conversion Date, or if the Holder requests the issuance of physical certificate(s), two Trading Days after receipt by the Corporation of the original certificate(s) representing such shares of Series A Preferred Stock being converted, duly endorsed, and the accompanying Notice of Conversion (the “ Share Delivery Date ”), the Corporation shall (a) deliver, or cause to be delivered, to the converting Holder a physical certificate or certificates representing the number of Conversion Shares being acquired upon the conversion of shares of Series A Preferred Stock or (b) in the case of a DWAC Delivery, electronically transfer such Conversion Shares by crediting the account of the Holder’s prime broker with DTC through its DWAC system. If in the case of any Notice of Conversion such certificate or certificates are not delivered to or as directed by or, in the case of a DWAC Delivery, such shares are not electronically delivered to or as directed by, the applicable Holder by the Share Delivery Date, the applicable Holder shall be entitled to elect to rescind such Conversion Notice by written notice to the Corporation at any time on or before its receipt of such certificate or certificates for Conversion Shares or electronic receipt of such shares, as applicable, in which event the Corporation shall promptly return to such Holder any original Series A Preferred Stock certificate delivered to the Corporation and such Holder shall promptly return to the Corporation any Common Stock certificates or otherwise direct the return of any shares of Common Stock delivered to the Holder through the DWAC system, representing the shares of Series A Preferred Stock unsuccessfully tendered for conversion to the Corporation.

ii. Obligation Absolute . Subject to Section 6(c) hereof and subject to Holder’s right to rescind a Conversion Notice pursuant to Section 6(d)(i) above, the Corporation’s obligation to issue and deliver the Conversion Shares upon conversion of Series A

Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by a Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by such Holder or any other Person of any obligation to the Corporation or any violation or alleged violation of law by such Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Corporation to such Holder in connection with the issuance of such Conversion Shares. Subject to Section 6(c) hereof and subject to Holder’s right to rescind a Conversion Notice pursuant to Section 6(d)(i) above, in the event a Holder shall elect to convert any or all of its Series A Preferred Stock, the Corporation may not refuse conversion based on any claim that such Holder or any one associated or affiliated with such Holder has been engaged in any violation of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and/or enjoining conversion of all or part of the Series A Preferred Stock of such Holder shall have been sought and obtained by the Corporation, and the Corporation posts a surety bond for the benefit of such Holder in the amount of 150% of the value of the Conversion Shares into which would be converted the Series A Preferred Stock which is subject to such injunction, which bond shall remain in effect until the completion of arbitration/litigation of the underlying dispute and the proceeds of which shall be payable to such Holder to the extent it obtains judgment. In the absence of such injunction, the Corporation shall, subject to Section 6(c) hereof and subject to Holder’s right to rescind a Conversion Notice pursuant to Section 6(d)(i) above, issue Conversion Shares upon a properly noticed conversion. Nothing herein shall limit a Holder’s right to pursue actual damages for the Corporation’s failure to deliver Conversion Shares within the period specified herein and such Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief; provided that Holder shall not receive duplicate damages for the Corporation’s failure to deliver Conversion Shares within the period specified herein. The exercise of any such rights shall not prohibit a Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

iii. Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Conversion . If the Corporation fails to deliver to a Holder the applicable certificate or certificates or to effect a DWAC Delivery, as applicable, by the Share Delivery Date pursuant to Section 6(d)(i) (other than a failure caused by incorrect or incomplete information provided by Holder to the Corporation), and if after such Share Delivery Date such Holder is required by its brokerage firm to purchase (in an open market transaction or otherwise), or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by such Holder of the Conversion Shares which such Holder was entitled to receive upon the conversion relating to such Share Delivery Date (a “ Buy-In ”), then the Corporation shall (A) pay in cash to such Holder (in addition to any other remedies available to or elected by such Holder) the amount by which (x) such Holder’s total purchase price (including any brokerage commissions) for the shares of Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common Stock that such Holder was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of such Holder, either reissue (if surrendered) the shares of Series A Preferred Stock equal to the number of shares of Series A Preferred Stock submitted for conversion or deliver to such

Holder the number of shares of Common Stock that would have been issued if the Corporation had timely complied with its delivery requirements under Section 6(d)(i). For the avoidance of doubt, this Section 6(d)(ii) shall not apply if the Corporation does not effect a conversion pursuant to the limitations of Section 6(c). For example, if a Holder purchases shares of Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Series A Preferred Stock with respect to which the actual sale price (including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, the Corporation shall be required to pay such Holder $1,000. The Holder shall provide the Corporation written notice, within three (3) Trading Days after the occurrence of a Buy-In, indicating the amounts payable to such Holder in respect of such Buy-In together with applicable confirmations and other evidence reasonably requested by the Corporation. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Corporation’s failure to timely deliver certificates representing shares of Common Stock upon conversion of the shares of Series A Preferred Stock as required pursuant to the terms hereof; provided, however, that the Holder shall not be entitled to both (i) require the reissuance of the shares of Series A Preferred Stock submitted for conversion for which such conversion was not timely honored and (ii) receive the number of shares of Common Stock that would have been issued if the Corporation had timely complied with its delivery requirements under Section 6(d)(i).

iv. Reservation of Shares Issuable Upon Conversion . The Corporation covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of the Series A Preferred Stock, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holders of the Series A Preferred Stock, not less than such aggregate number of shares of the Common Stock as shall be issuable (taking into account the adjustments of Section 7) upon the conversion of all outstanding shares of Series A Preferred Stock. The Corporation covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and nonassessable.

v. Fractional Shares . No fractional shares or scrip representing fractional shares of Common Stock shall be issued upon the conversion of the Series A Preferred Stock. As to any fraction of a share which a Holder would otherwise be entitled to receive upon such conversion, the Corporation shall pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Conversion Price.

vi. Transfer Taxes . The issuance of certificates for shares of the Common Stock upon conversion of the Series A Preferred Stock shall be made without charge to any Holder for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificates, provided that the Corporation shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the registered Holder(s) of such shares of Series A Preferred Stock and the Corporation shall not be required to issue or deliver such certificates unless or until the Person or Persons requesting the issuance thereof shall have paid to the Corporation the amount of such tax or shall have established to the satisfaction of the Corporation that such tax has been paid.

e. Status as Stockholder . Upon each Conversion Date, (i) the shares of Series A Preferred Stock being converted shall be deemed converted into shares of Common Stock and (ii) the Holder’s rights as a holder of such converted shares of Series A Preferred Stock shall cease and terminate, excepting only the right to receive certificates for such shares of Common Stock and to any remedies provided herein or otherwise available at law or in equity to such Holder because of a failure by the Corporation to comply with the terms of this Certificate of Designation. In all cases, the Holder shall retain all of its rights and remedies for the Corporation’s failure to convert Series A Preferred Stock.

Section 7. Certain Adjustments .

a. Stock Dividends and Stock Splits . If the Corporation, at any time while any Series A Preferred Stock is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Corporation upon conversion of any Series A Preferred Stock) with respect to the then outstanding shares of Common Stock; (ii) subdivides outstanding shares of Common Stock into a larger number of shares; or (iii) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding any treasury shares of the Corporation) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event (excluding any treasury shares of the Corporation). Any adjustment made pursuant to this Section 7(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination.

b. Fundamental Transaction . If, at any time while any Series A Preferred Stock is outstanding, (i) the Corporation effects any merger or consolidation of the Corporation with or into another Person (other than a merger in which the Corporation is the surviving or continuing entity and its Common Stock is not exchanged for or converted into other securities, cash or property), (ii) the Corporation effects any sale of all or substantially all of its assets in one transaction or a series of related transactions, (iii) any tender offer or exchange offer (whether by the Corporation or another Person) is completed pursuant to which all of the Common Stock is exchanged for or converted into other securities, cash or property, or (iv) the Corporation effects any reclassification of the Common Stock or any compulsory share exchange pursuant (other than as a result of a dividend, subdivision or combination covered by Section 7(a) above) to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (in any such case, a “ Fundamental Transaction ”), then, upon any subsequent conversion of Series A Preferred Stock the Holders shall have the right to receive, in lieu of the right to receive Conversion Shares, for each Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence of such Fundamental Transaction, the same kind and amount of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of one share of Common Stock (the “ Alternate Consideration ”). For purposes of any such subsequent conversion, the determination of the Conversion Ratio shall be appropriately adjusted to apply to such Alternate

Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Corporation shall adjust the Conversion Ratio in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holders shall be given the same choice as to the Alternate Consideration it receives upon any conversion of Series A Preferred Stock following such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Corporation or surviving entity in such Fundamental Transaction shall file a new Certificate of Designation with the same terms and conditions and issue to the Holders new preferred stock consistent with the foregoing provisions and evidencing the Holders’ right to convert such preferred stock into Alternate Consideration. The terms of any agreement to which the Corporation is a party and pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this Section 7(b) and insuring that the Series A Preferred Stock (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction. The Corporation shall cause to be delivered to each Holder, at its last address as it shall appear upon the stock books of the Corporation, written notice of any Fundamental Transaction at least 10 calendar days prior to the date on which such Fundamental Transaction is expected to become effective or close.

c. Calculations . All calculations under this Section 7 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 7, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding any treasury shares of the Corporation) issued and outstanding.

d. Notice to the Holders .

i. Adjustment to Conversion Price . Whenever the Conversion Price is adjusted pursuant to any provision of this Section 7, the Corporation shall promptly deliver to each Holder a notice setting forth the Conversion Ratio after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

ii. Other Notices . If (A) the Corporation shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Corporation shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Corporation shall authorize the granting to all holders of the Common Stock of rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Corporation shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Corporation is a party, any sale or transfer of all or substantially all of the assets of the Corporation, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, or (E) the Corporation shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Corporation, then, in each case, the Corporation shall cause to be filed at each office or agency maintained for the purpose of conversion of the Series A Preferred Stock, and shall cause to be delivered to each Holder at its last address as it shall appear upon the stock books of the Corporation, at least 10 calendar days prior to the

applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange, provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice.

Section 8. Miscellaneous .

a. Redemption . The Series A Preferred Stock is not redeemable.

b. Notices . Any and all notices or other communications or deliveries to be provided by the Holders hereunder including, without limitation, any Notice of Conversion, shall be in writing and delivered personally, via email, by facsimile, or sent by a nationally recognized overnight courier service, addressed to the Corporation, at 225 State Street, 9 ^th Floor, Boston, MA, email deptula@pieris.com , or such other facsimile number or address as the Corporation may specify for such purposes by notice to the Holders delivered in accordance with this Section. Any and all notices or other communications or deliveries to be provided by the Corporation hereunder shall be in writing and delivered personally, by facsimile, or sent by a nationally recognized overnight courier service addressed to each Holder at the facsimile number or address of such Holder appearing on the books of the Corporation, or if no such facsimile number or address appears on the books of the Corporation, at the principal place of business of such Holder. Any notice or other communication or deliveries hereunder shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in this Section prior to 5:30 p.m. (New York City time) on any date, (ii) the date immediately following the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in this Section between 5:30 p.m. and 11:59 p.m. (New York City time) on any date, (iii) the second Business Day following the date of mailing, if sent by nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom such notice is required to be given.

c. Lost or Mutilated Series A Preferred Stock Certificate . If a Holder’s Series A Preferred Stock certificate shall be mutilated, lost, stolen or destroyed, the Corporation shall execute and deliver, in exchange and substitution for and upon cancellation of a mutilated certificate, or in lieu of or in substitution for a lost, stolen or destroyed certificate, a new certificate for the shares of Series A Preferred Stock so mutilated, lost, stolen or destroyed, but only upon receipt of evidence of such loss, theft or destruction of such certificate, and of the ownership thereof, reasonably satisfactory to the Corporation and, in each case, customary and reasonable indemnity, if requested. Applicants for a new certificate under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable third-party costs as the Corporation may prescribe.

d. Waiver . Any waiver by the Corporation or a Holder of a breach of any provision of this Certificate of Designation shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Certificate of Designation or a waiver by any other Holders. The failure of the Corporation or a Holder to insist upon strict adherence to any term of this Certificate of Designation on one or more occasions shall not be considered a waiver or deprive that party (or any other Holder) of the right thereafter to insist upon strict adherence to that term or any other term of this Certificate of Designation. Any waiver by the Corporation or a Holder must be in writing. Notwithstanding any provision in this Certificate of Designation to the contrary, any provision contained herein and any right of the Holders of Series A Preferred Stock granted hereunder may be waived as to all shares of Series A Preferred Stock (and the Holders thereof) upon the written consent of the Holders of not less than a majority of the shares of Series A Preferred Stock then outstanding, unless a higher percentage is required by the NRS, in which case the written consent of the Holders of not less than such higher percentage shall be required.

e. Severability . If any provision of this Certificate of Designation is invalid, illegal or unenforceable, the balance of this Certificate of Designation shall remain in effect, and if any provision is inapplicable to any Person or circumstance, it shall nevertheless remain applicable to all other Persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder violates the applicable law governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum rate of interest permitted under applicable law.

f. Next Business Day . Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day.

g. Headings . The headings contained herein are for convenience only, do not constitute a part of this Certificate of Designation and shall not be deemed to limit or affect any of the provisions hereof.

h. Status of Converted Series A Preferred Stock . If any shares of Series A Preferred Stock shall be converted or reacquired by the Corporation, such shares shall, without need for any action by the Board of Directors or otherwise, resume the status of authorized but unissued shares of preferred stock and shall no longer be designated as Series A Preferred Stock.

OF SERIES A PREFERRED STOCK)

The undersigned Holder hereby irrevocably elects to convert the number of shares of Series A Convertible Preferred Stock indicated below, represented by stock certificate No(s). (the “ Preferred Stock Certificates ”), into shares of common stock, par value $0.001 per share (the “ Common Stock ”), of Pieris Pharmaceuticals, Inc., a Nevada corporation (the “ Corporation ”), as of the date written below.

5.2. Payment Currency . All payments due under this Agreement will be paid in U.S. Dollars. Conversion of foreign currency to U.S. Dollars will be made at the conversion rate existing in the United States (as reported in the Wall Street Journal) on the last working day of the applicable Calendar Quarter. Such payments will be without deduction of exchange, collection or other charges.

5.3. Records . Pieris shall maintain, and shall, if applicable, cause its Affiliates to maintain, complete and accurate records of Products that are sold, leased or transferred under this Agreement, any amounts payable to Enumeral in relation to such Products, which records shall contain sufficient information to permit Enumeral to confirm the accuracy of any reports or notifications delivered to Enumeral under Section 5.1. Pieris and its Affiliates, as applicable, shall retain such records relating to a given Calendar Quarter for at least [***] years after the conclusion of that Calendar Quarter, during which time Enumeral will have the right, at its expense, to cause an independent, certified public accountant to inspect such records of Pieris during normal business hours for the purposes of verifying the accuracy of any reports and payments delivered under this Agreement and Pieris’ compliance with the terms hereof. Such accountant or other auditor, as applicable, shall not disclose to Enumeral any information other than information relating to the accuracy of reports and payments delivered under this Agreement. The Parties shall reconcile any underpayment or overpayment within [***] days after the accountant delivers the results of the audit. If any audit performed under this Section 5.3 reveals an underpayment in excess of [***] in any calendar year, Pieris shall reimburse Enumeral for all amounts incurred in connection with such audit. For avoidance of doubt, Enumeral shall not have the right to audit or inspect Sublicensee(s) directly but may audit or inspect any applicable materials received from Sublicensee and in the possession of Pieris. Pieris, however, shall audit Sublicensees and require royalty and milestone reports in connection with any Sublicense. Enumeral may exercise its rights under this Section 5.3 only once every 12-month period and only with reasonable prior notice.

5.4. Late Payments . Any payments by Pieris that are not paid on or before the date such payments are due under this Agreement will bear interest at [***] per month. Interest will accrue beginning on the first day following the due date for payment and will be compounded quarterly. Payment of such interest by Pieris shall not limit, in any way, Enumeral’s right to exercise any other remedies Enumeral may have as a consequence of the lateness of any payment.

5.5. Payment Method . Each payment due to Enumeral under this Agreement shall be paid by check or wire transfer of funds to Enumeral’s account in accordance with written instructions provided by Enumeral. If made by wire transfer, such payments shall be marked so as to refer to this Agreement.

5.6. Withholding and Similar Taxes . Enumeral will be responsible for and will pay all applicable taxes on all payments received from Pieris in connection with this Agreement. If Pieris is required to withhold any amounts payable hereunder to Enumeral due to the applicable laws of any country, such amount will be deducted from the payment to be made by Pieris and remitted to the appropriate taxing authority for the benefit of Enumeral. Pieris will withhold only such amounts as are required to be withheld by applicable law in the
