Item 1.01. Entry Into a Material Definitive Agreement.

On August 7, 2024, Pieris Pharmaceuticals, Inc. (the “Company”) entered into a Subscription and Investment Representation Agreement (the “Subscription Agreement”) with James Geraghty (the “Purchaser”), Chairman of the Company’s Board of Directors (the “Board”), pursuant to which the Company agreed to issue and sell one (1) share of the Company’s Series F Preferred Stock, par value $0.001 per share (the “Preferred Stock”), to the Purchaser for $1.00 cash. The sale closed on August 7, 2024. Additional information regarding the rights, preferences, privileges and restrictions applicable to the Preferred Stock is contained in Item 5.03 of this Current Report on Form 8-K (the “Report”) and incorporated by reference herein.

The Subscription Agreement contains customary representations and warranties and certain indemnification rights and obligations of the parties. The Subscription Agreement also provides that the Purchaser shall (a) attend any special meeting of the stockholders of the Company upon which the Authorized Share Increase (as defined below) is scheduled to be voted, (b) vote the Preferred Stock with regard to the Authorized Share Increase in the manner set forth in the Certificate of Designation (as defined below) and (c) upon request by the Company, grant an irrevocable proxy to vote the Preferred Stock in accordance with the foregoing to a designee of the Company.

The foregoing description of the Subscription Agreement does not purport to be complete and is subject to, and qualified by, the full text of such document, a copy of which is filed as Exhibit 10.1 hereto and incorporated by reference herein.

Item 3.02 Unregistered Sales of Equity Securities.

The information contained in Item 1.01 of this Report is incorporated by reference herein.  Based in part upon the representations of the Purchaser in the Subscription Agreement, the offering and sale of the Preferred Stock was exempt from registration under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”).

Item 3.03 Material Modifications to Rights of Security Holders.

The information contained in Item 5.03 of this Report is incorporated by reference herein.

Certificate of Designation

On August 7, 2024, the Company filed a certificate of designation (the “Certificate of Designation”) with the Nevada Secretary of State, effective as of the time of filing, designating the rights, preferences, privileges and restrictions of the share of Preferred Stock. The Certificate of Designation provides that the share of Preferred Stock will have 25,000,000 votes and will vote together with the outstanding shares of the Company’s common stock as a single class exclusively with respect to any proposal to amend the Company’s Amended and Restated Articles of Incorporation to effect an increase in the number of authorized shares of the Company’s common stock (the “Authorized Share Increase”). The Preferred Stock will be voted, without action by the holder, on any such proposal in the same proportion as shares of common stock are voted (excluding any shares of common stock that are not voted “for” or “against” the Authorized Share Increase for any reason, including, without limitation, any abstentions or broker non-votes). The Preferred Stock otherwise has no other voting rights except as otherwise mandated by applicable law, and any rights to vote except as described above with respect to the Authorized Share Increase are specifically denied.

The Preferred Stock is not convertible into, or exchangeable for, shares of any other class or series of stock or other securities of the Company. The Preferred Stock has no rights with respect to any distribution of assets of the Company, including upon a liquidation, bankruptcy, reorganization, merger, acquisition, sale, change of control, dissolution or winding up of the Company, whether voluntarily or involuntarily. The holder of the Preferred Stock will not be entitled to receive dividends of any kind.

The outstanding share of Preferred Stock may be redeemed in whole, but not in part, upon the earlier to occur of: (i) the order of the Board in its sole discretion, automatically and effective at such date and time as is determined and specified by the Board in its sole discretion and (ii) automatically and effective immediately after the effectiveness of the Authorized Share Increase. Upon such redemption, the holder of the Preferred Stock would receive consideration of $0.01 in cash.

The foregoing description of the Certificate of Designation does not purport to be complete and is subject to, and qualified by, the full text of such document, a copy of which is filed as Exhibit 3.1 hereto and is incorporated by reference herein.

Exhibit 10.1

Pieris Pharmaceuticals, Inc.

Series F Preferred Stock

SUBSCRIPTION AND INVESTMENT REPRESENTATION AGREEMENT

THIS AGREEMENT, dated as of August 7, 2024, is by and between Pieris Pharmaceuticals, Inc., a Nevada corporation (the “Company”), and the undersigned subscriber (the “Subscriber”). In consideration of the mutual promises contained herein, and other good, valuable and adequate consideration, the parties hereto agree as follows:

1. Agreement of Sale; Closing. The Company agrees to sell to Subscriber, and Subscriber agrees to purchase from the Company, one (1) share of the Company’s Series F Preferred Stock, par value $0.001 per share (the “Securities”), which shall have the rights, preferences, privileges and restrictions set forth in the Certificate of Designation attached hereto as Exhibit A (the “Certificate of Designation”). Subscriber hereby acknowledges and agrees to the entire terms of the Certificate of Designation, including, without limitation, the voting rights in Section 3 thereof, the restrictions on transfer of the Securities in Section 5 thereof and the redemption of the Securities pursuant to Section 6 thereof. The purchase price will be paid by the Subscriber to the Company in cash at the price of $1.00 in the aggregate.

2. Voting Agreement. Subscriber agrees to (a) attend any special meeting of the stockholders of the Company upon which the Authorized Stock Increase (as such term is defined in the Certificate of Designation) is scheduled to be voted, (b) vote all Securities with regard to the Authorized Stock Increase in the manner set forth in the Certificate of Designation and (c) upon request by the Company, grant an irrevocable proxy to vote the Securities in accordance with the foregoing to a designee of the Company

3. Representations and Warranties of Subscriber. In consideration of the Company’s offer to sell the Securities, and in addition to the purchase price to be paid, Subscriber hereby covenants, represents and warrants to the Company as follows: 

a. Information About the Company.

i. Subscriber is aware that the Company is not profitable and that its financial projections and future are purely speculative.

ii. Subscriber has had an opportunity to ask questions of, and receive answers from, the Company concerning the business, management, and financial and compliance affairs of the Company and the terms and conditions of the purchase of the Securities contemplated hereby. Subscriber has had an opportunity to obtain, and has received, any additional information deemed necessary by the Subscriber to verify such information in order to form a decision concerning an investment in the Company. 

b. Restrictions on Transfer. Subscriber covenants, represents and warrants that the Securities are being purchased for Subscriber’s own personal account and for Subscriber’s individual investment and without the intention of reselling or redistributing the same, that Subscriber has made no agreement with others regarding any of such Securities, and that Subscriber’s financial condition is such that it is not likely that it will be necessary to dispose of any of the Securities in the foreseeable future. Moreover, Subscriber acknowledges that any of the aforementioned actions may require the prior written consent of the Company’s board of directors pursuant to the Certificate of Designation. Subscriber is aware that, in the view of the Securities and Exchange Commission, a purchase of the Securities with an intent to resell by reason of any foreseeable specific contingency or anticipated change in market values, or any change in the condition of the Company, or in connection with a contemplated liquidation or settlement of any loan obtained by Subscriber for the acquisition of the Securities and for which the Securities were pledged as security, would represent an intent inconsistent with the covenants, warranties and representations set forth above. Subscriber understands that the Securities have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state or foreign securities laws in reliance on exemptions from registration under these laws, and that, accordingly, the Securities may not be resold by the undersigned (i) unless they are registered under both the Securities Act and applicable state or foreign securities laws or are sold in transactions which are exempt from such registration, and (ii) except in compliance with Section 5 of the Certificate of Designation, which may require the prior written consent of the Company’s board of directors. Subscriber therefore agrees not to sell, assign, transfer or otherwise dispose of the Securities (i) unless a registration statement relating thereto has been duly filed and become effective under the Securities Act and applicable state or foreign securities laws, or unless in the opinion of counsel satisfactory to the Company no such registration is required under the circumstances, and (ii) except in compliance with Section 5 of the Certificate of Designation. There is not currently, and it is unlikely that in the future there will exist, a public market for the Securities; and accordingly, for the above and other reasons, Subscriber may not be able to liquidate an investment in the Securities for an indefinite period.

1

d. High Degree of Economic Risk. Subscriber realizes that an investment in the Securities involves a high degree of economic risk to the Subscriber, including the risks of receiving no return on the investment and/or of losing Subscriber’s entire investment in the Company. Subscriber is able to bear the economic risk of investment in the Securities, including the total loss of such investment. The Company can make no assurance regarding its future financial performance or as to the future profitability of the Company.

e. Suitability. Subscriber has such knowledge and experience in financial, legal and business matters that Subscriber is capable of evaluating the merits and risks of an investment in the Securities. Subscriber has obtained, to the extent deemed necessary, Subscriber’s own personal professional advice with respect to the risks inherent in, and the suitability of, an investment in the Securities in light of Subscriber’s financial condition and investment needs. Subscriber believes that the investment in the Securities is suitable for Subscriber based upon Subscriber’s investment objectives and financial needs, and Subscriber has adequate means for providing for Subscriber’s current financial needs and personal contingencies and has no need for liquidity of investment with respect to the Securities. Subscriber understands that no federal or state agency has made any finding or determination as to the fairness for investment, nor any recommendation or endorsement, of the Securities.

f. Tax Liability. Subscriber has reviewed with Subscriber’s own tax advisors the federal, state, local and foreign tax consequences of this investment and the transactions contemplated by this Agreement, and has and will rely solely on such advisors and not on any statements or representations of the Company or any of its agents, representatives, employees, affiliates or subsidiaries. Subscriber understands that Subscriber (and not the Company) shall be responsible for Subscriber’s own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement. Under penalties of perjury, Subscriber certifies that Subscriber is not subject to back-up withholding either because Subscriber has not been notified that Subscriber is subject to back-up withholding as a result of a failure to report all interest and dividends, or because the Internal Revenue Service has notified Subscriber that Subscriber is no longer subject to back-up withholding.

g. Limitation Regarding Representations. Except as set forth in this Agreement, no covenants, representations or warranties have been made to Subscriber by the Company or any agent, representative, employee, director or affiliate or subsidiary of the Company and in entering into this transaction, Subscriber is not relying on any information, other than that contained herein and the results of independent investigation by Subscriber without any influence by Company or those acting on Company’s behalf. Subscriber agrees it is not relying on any oral or written information not expressly included in this Agreement, including but not limited to the information which has been provided by the Company, its directors, its officers or any affiliate or subsidiary of any of the foregoing.

h. Authority.

i. Entity. If the undersigned is not an individual but an entity, the individual signing on behalf of such entity and the entity jointly and severally agree and certify that (a) the undersigned was not organized for the specific purpose of acquiring the Securities and (b) this Agreement has been duly authorized by all necessary action(s) on the part of the undersigned, has been duly executed by an authorized officer, agent or representative of the undersigned, and is a legal, valid and binding obligation of the undersigned enforceable in accordance with its terms.

ii. Individual. If the undersigned is an individual, the undersigned is of legal age.

Moreover, these Securities may be transferred only in accordance with the terms of the Company’s Certificate of Designation of Series F Preferred Stock, a copy of which is on file with the Secretary of the Company.

THE UNDERSIGNED AGREES TO FURNISH ANY ADDITIONAL INFORMATION THAT THE COMPANY AND ITS COUNSEL DEEM NECESSARY TO VERIFY THE RESPONSES SET FORTH BELOW

5. Accredited Status. Subscriber covenants, represents and warrants that it qualifies as an “accredited investor” as that term is defined in Regulation D under the Securities Act. The information provided under this section of the Agreement is required in connection with the exemptions from the Securities Act and state securities laws being relied on by the Company with respect to the offer and sale of the Securities. The undersigned agrees to furnish any additional information which the Company or its legal counsel deem necessary in order to verify the responses set forth above.

6. Holding Status. Subscriber desires that the Securities be held as set forth on the signature page hereto.

7. Confidentiality. Subscriber will make no written or other public disclosures regarding the Company and its business, the terms or existence of the proposed or actual sale of Securities or regarding the parties to the proposed or actual sale of Securities to any individual or organization without the prior written consent of the Company, except as may be required by law.

8. Notice. Correspondence regarding the Securities should be directed to Subscriber at the address provided by Subscriber to the Company in writing.

9. No Assignment or Revocation; Binding Effect. Neither this Agreement, nor any interest herein, shall be assignable or otherwise transferable, restricted or limited by Subscriber without prior written consent of the Company. Subscriber hereby acknowledges and agrees that Subscriber is not entitled to cancel, terminate, modify or revoke this Agreement in any way and that the Agreement shall survive the death, incapacity or bankruptcy of Subscriber. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto, and their respective heirs, legal representatives, successors and assigns.

10. Indemnification. The Company agrees to indemnify and hold harmless the Subscriber and each current and future officer, director, employee, agent and representative, if any, of the Subscriber from and against any and all costs, expenses, loss, damage, judgments or liability associated with this Agreement and the issuance and voting of the Securities.

11. Modifications. This Agreement may not be changed, modified, released, discharged, abandoned or otherwise amended, in whole or in part, except by an instrument in writing, signed by the Subscriber and the Company.
