On March 28, 2024, Kiromic BioPharma, Inc. (the “Company”) entered into an Exchange Agreement (the “Exchange Agreement”) with the holder of promissory notes of the Company (the “Holder”) pursuant to which the Holder agreed to exchange aggregate principal amount of $8 million of the Company’s 25% Senior Secured Convertible Promissory Notes (the “Exchange Notes”) for 8,000 shares of Series D Convertible Voting Preferred Stock (the “Series D Preferred Stock”).  

The foregoing description of the Exchange Agreement is qualified in its entirety by reference to the full text of such Exchange Agreement, a copy of which is attached hereto as Exhibit 10 and incorporated herein by reference.

​

Reference is made to the disclosure set forth under Item 1.01 above, which disclosure is incorporated herein by reference. The exchange of the Exchange Notes for Series D Preferred Stock was made in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended.

​

The information contained above in Item 1.01 is hereby incorporated by reference into this Item 5.03.

Pursuant to the Exchange Agreement, on April 1, 2024, the Company filed the Certificate of Designation with the Delaware Secretary of State designating 8,000 shares of its authorized and unissued preferred stock as Series D Convertible Voting Preferred Stock.  The Certificate of Designation sets forth the rights, preferences and limitations of the shares of Series D Preferred Stock. Terms not otherwise defined in this item shall have the meanings given in the Certificate of Designation.

The following is a summary of the terms of the Series D Preferred Stock:

Dividends. Dividends will accrue, on all issued and outstanding shares of Series D Preferred Stock, prior to and in preference to all other shares of capital stock of the Company, at an annual rate of twenty-five percent (25%) compounded annually on the Original Per Share Price (plus any such accreted compounded amounts).  If such dividends are not declared and paid in cash, the dividend amounts will be added to the aggregate Liquidation Preference then outstanding of the Series D Preferred Stock (such dividends will accumulate and will be included in the payments made upon redemption or Liquidation.

​

At all times following the Issuance Date, while shares of Series D Preferred Stock are issued and outstanding, holders of Series D Preferred Stock shall be entitled to receive, and the Company shall pay, dividends on shares of Series D Preferred Stock equal (on an as-if-converted-to-Common-Stock basis and without regard to any limitations on conversion set forth herein or otherwise) to and in the same form as dividends (other than dividends in the form of Common Stock, which shall be made in accordance with the terms of the Certificate of Designation) actually paid on shares of the Common Stock when, as and if such dividends (other than dividends in the form of Common Stock, which shall be made in accordance with the terms of the Certificate of Designation) are paid on shares of the Common Stock.

​

Voting Rights. Subject to certain limitations described in the Certificate of Designation, the Series D Preferred Stock is voting stock. Holders of the Series D Preferred Stock are entitled to vote together with the Common Stock on an as-if-converted-to-Common-Stock basis. Holders of Common Stock are entitled to one vote for each share of Common Stock held on all matters submitted to a vote of stockholders. Accordingly, holders of Series D Preferred Stock will be entitled to one vote for each whole share of Common Stock into which their Series D Preferred Stock is then-convertible on all matters submitted to a vote of stockholders.

​

Liquidation. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company, including a change of control transaction, or Deemed Liquidation Event (any such event, a “Liquidation”) the holders of shares of Series D Preferred Stock then outstanding shall be entitled to be paid out of the assets of the Company available

​

for distribution to its stockholders, and in the event of a Deemed Liquidation Event, the holders of shares of Series D Preferred Stock then outstanding shall be entitled to be paid out of the consideration payable to stockholders in such Deemed Liquidation Event or the other proceeds available for distribution to stockholders, before any payment shall be made to the holders of any other shares of capital stock of the Company by reason of their ownership thereof, an amount per share equal to the greater of (i) one times (1x) the Original Per Share Price, plus any Accruing Dividends accrued but unpaid thereon, whether or not declared, together with any other dividends declared but unpaid thereon (the “Liquidation Preference”) or (ii) such amount per share as would have been payable had all shares of Series D Preferred Stock been converted into Common Stock (without regard to any limitations on conversion set forth in the Certificate of Designation or otherwise) immediately prior to such Liquidation (the amount payable pursuant to this sentence is hereinafter referred to as the “Series A Liquidation Amount”). If upon any such Liquidation, the assets of the Company available for distribution to its stockholders shall be insufficient to pay the holders of shares of Series D Preferred Stock the full Liquidation Preference, the holders of shares of Series D Preferred Stock shall share ratably in any distribution of the assets available for distribution in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full. After the payment in full of all Series D Liquidation Amount, the remaining assets of the Company available for distribution to its stockholders or, in the case of a Deemed Liquidation Event, the consideration not payable to the holders of shares of Series D Preferred Stock pursuant to the Certificate of Designation shall be distributed among the holders of shares of Common Stock, pro rata based on the number of shares held by each such holder.

​

Upon any Liquidation, the assets of the Company available for distribution to its stockholders shall be distributed among the holders of the shares of Series D Preferred Stock and Common Stock, pro rata based on the number of shares held by each such holder, treating for this purpose all shares of Series D Preferred Stock as if they had been converted to Common Stock pursuant to the terms of the Certificate of Designation immediately prior to such Liquidation, without regard to any limitations on conversion set forth in the Certificate of Designation or otherwise.

​

Conversion.  Each share of Series D Preferred Stock shall be convertible into the number of shares of Common Stock equal to the quotient of (A) the Liquidation Preference as of the Conversion Date divided by (B) the Conversion Price on the Conversion Date.

​

Conversion Price. The Conversion Price for the Series D Preferred Stock is $2.50 per share.

​

Redemption. Unless prohibited by Delaware law governing distributions to stockholders, the Company may redeem 100% of the shares of Series D Preferred Stock at any time at a price equal to the then Liquidation Preference.

​

The foregoing summary of the terms of the Series D Preferred Stock is qualified in its entirety by reference to the text of the Certificate of Designation, which is filed hereto as Exhibit 3.1 and is incorporated herein by reference.

​

shall be credited to the DTC participant account nominated by the Holder through DTC’s Deposit Withdrawal Agent Commission system (a “DWAC Delivery”). The date on which such a conversion shall be deemed effective (an “Optional Conversion Date”, and together with the Automatic Conversion Date, a “Conversion Date”), shall be defined as the Trading Day that the Notice of Conversion, completed and executed, is sent by facsimile or other electronic transmission to, and received during regular business hours by, the Corporation and its transfer agent. The calculations set forth in the Notice of Conversion shall control in the absence of manifest or mathematical error.

​

(ii)Delivery of Electronic Issuance Upon Conversion. Not later than two (2) Trading Days after the applicable Conversion Date (the “Share Delivery Date”), the Corporation’s transfer agent shall (a) in the case of a DWAC Delivery (if so requested by the Holder), electronically transfer such Conversion Shares by crediting the DTC participant account nominated by the Holder through DTC’s DWAC system or (b) if the shares of Series D Preferred Stock being converted have been issued in global form eligible for book-entry settlement with DTC, the Conversion Shares shall be delivered to the Holder through book-entry transfer through the facilities of DTC. If 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 and its transfer agent at any time on or before its electronic receipt of such shares, as applicable, in which event the Corporation’s transfer agent shall promptly direct the return of any shares of Common Stock delivered to the Holder through the DWAC system, representing the shares of Series D Preferred Stock unsuccessfully tendered for conversion to the Corporation.

​

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

​

(iv)Intentionally omitted.

​

(v)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 D Preferred Stock, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holders of the Series D 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 D Preferred Stock. Such reservation shall comply without regard to the provisions of Section 6(f). The Corporation covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid, non-assessable and free and clear of all liens and other encumbrances.

​

(vi)Fractional Shares. No fractional shares or scrip representing fractional shares of Common Stock shall be issued upon the conversion of the Series D Preferred Stock. All fractional shares shall be rounded down to the nearest whole shares of Common Stock.

​

(vii)Transfer Taxes. The issuance of book entry notations for shares of the Common Stock upon conversion of the Series D 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 book entry notation, provided that the Corporation shall not be required to pay any tax that may be payable in respect of any transfer involved in

​

5

the issuance and delivery of any such book entry notation upon conversion in a name other than that of the registered Holder(s) of such shares of Series D Preferred Stock and the Corporation shall not be required to issue or deliver such book entry notation 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 in which the Series D Preferred Stock converts into Common Stock: (i) the shares of Series D 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 D Preferred Stock shall cease and terminate, excepting only the right to receive book entry notations 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 D Preferred Stock.

​

(f)Limitations on Conversion. Except as set forth in this Section 6(f), a Holder shall not have the right to convert any portion of the Series D Preferred Stock and such Series D Preferred Stock shall not be automatically converted, to the extent that after giving effect to such conversion, such Holder (together with such Holder’s Affiliates, any other Persons acting as a group together, and any other Persons whose beneficial ownership of Common Stock would be aggregated with the Holder’s and the other Attribution Parties for purposes of Section 13(d) of the Exchange Act (such Persons, “Attribution Parties”)) would beneficially own in excess of 19.99% (the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such conversion. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such Person and its Affiliates shall include the number of shares of Common Stock issuable upon conversion of the Series D Preferred Stock with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon (i) exercise of the remaining, unconverted portion of the Series D Preferred Stock beneficially owned by such Person and its Affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Corporation beneficially owned by such Person and its Affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. For purposes of this Section 6(f), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Corporation’s most recent Form 10-K, Proxy Statement, Form 10-Q, Current Report on Form 8-K or other public filing with the Commission, as the case may be, (2) a more recent public announcement by the Corporation or (3) any other notice by the Corporation or the Corporation’s transfer agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request of a Holder, where such request indicates that it is being made pursuant to this Section 6(f), the Corporation shall within one (1) Trading Day confirm orally and in writing to such Holder 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 the conversion or exercise of securities of the Corporation, including the Series D Preferred Stock, by a Holder and its Affiliates since the date as of which such number of outstanding shares of Common Stock was reported. Upon delivery of a written notice to the Corporation, a Holder may from time to time increase or decrease the Maximum Percentage to any other percentage as specified in such notice; provided that (i) any such increase in the Maximum Percentage will not be effective until the sixty-first (61st) day after such notice is delivered to the Corporation and (ii) any such increase or decrease will apply only to such Holder and not to any other holder of Series D Preferred Stock. For purposes of clarity, the shares of Common Stock issuable pursuant to the terms hereof in excess of the Maximum Percentage shall not be deemed to be beneficially owned by a Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the Exchange Act. No prior inability to convert Series D Preferred Stock pursuant to this Section 6(f) shall have any effect on the applicability of the provisions of this Section 6(f) with respect to any subsequent determination of whether Series D Preferred Stock may be converted. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 6(f) to the extent necessary to correct this paragraph or any portion of this paragraph which may be defective or inconsistent with the intended beneficial ownership limitation contained in this Section 6(f) or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations set forth in this Section 6(f) shall not apply to any conversions of the Series D Preferred that occur prior to and expressly in connection with a Deemed Liquidation Event.

​

​

(a)Stock Dividends and Stock Splits. If the Corporation, at any time while any shares of Series D Preferred Stock are outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions payable in shares of Common 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)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.

​

​

7

(b)Redemption Notice. The Corporation shall send written notice of the redemption (the “Redemption Notice”) to each holder of record of Series D Preferred Stock not less than forty (40) days prior to the Redemption Date. The Redemption Notice shall state:

​

(i)the number of shares of Series D Preferred Stock held by the holder that the Corporation shall redeem on the Redemption Date specified in the Redemption Notice;

(ii)the Redemption Price;

(iii)the date upon which the holder’s right to convert such shares terminates (which shall be the date that is one Business Day immediately preceding the Redemption Date); and

(iv)for holders of shares in certificated form, that the holder is to surrender to the Corporation, in the manner and at the place designated, his, her or its certificate or certificates representing the shares of Series D Preferred Stock to be redeemed.

(c)Surrender of Certificates; Payment. On or before the Redemption Date, each holder of shares of Series D Preferred Stock to be redeemed on the Redemption Date, unless such holder has exercised his, her or its right to convert such shares as provided in Section 6, shall, if a holder of shares in certificated form, surrender the certificate or certificates representing such shares (or, if such registered holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Corporation to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate) to the Corporation, in the manner and at the place designated in the Redemption Notice, and thereupon the Redemption Price for such shares shall be payable to the order of the person whose name appears on such certificate or certificates as the owner thereof. In the event less than all of the shares of Series D Preferred Stock represented by a certificate are redeemed, a new certificate, instrument, or book entry representing the unredeemed shares of Series D Preferred Stock shall promptly be issued to such holder.

(d)Interest. If any shares of Series D Preferred Stock are not redeemed for any reason on the Redemption Date, all such unredeemed shares shall remain outstanding and entitled to all the rights and preferences provided herein, and the Corporation shall pay interest on the Redemption Price applicable to such unredeemed shares at an aggregate per annum rate equal to 10% (increased by one percent (1%) each month following the Redemption Date until the Redemption Price, and any interest thereon, is paid in full), with such interest to accrue daily in arrears and be compounded annually; provided, however, that in no event shall such interest exceed the maximum permitted rate of interest under applicable law (the “Maximum Permitted Rate”), provided, however, that the Corporation shall take all such actions as may be necessary, including without limitation, making any applicable governmental filings, to cause the Maximum Permitted Rate to be the highest possible rate. In the event any provision hereof would result in the rate of interest payable hereunder being in excess of the Maximum Permitted Rate, the amount of interest required to be paid hereunder shall automatically be reduced to eliminate such excess; provided, however, that any subsequent increase in the Maximum Permitted Rate shall be retroactively effective to the Redemption Date to the extent permitted by law.

(e)Rights Subsequent to Redemption. If the Redemption Notice shall have been duly given, and if on the Redemption Date the Redemption Price (including any accrued and unpaid interest as provided in Section 9(d) above) payable upon redemption of the shares of Series D Preferred Stock to be redeemed on the Redemption Date is paid or tendered for payment or deposited with an independent payment agent so as to be available therefor in a timely manner, then notwithstanding that any certificates evidencing any of the shares of Series D Preferred Stock so called for redemption shall not have been surrendered, dividends with respect to such shares of Series D Preferred Stock shall cease to accrue after the Redemption Date and all rights with respect to such shares shall forthwith after the Redemption Date terminate, except only the right of the holders to receive the Redemption Price (plus accrued and unpaid interest as provided in Section 9(d) above) upon surrender of any such certificate or certificates therefor.

​

Section 10. Intentionally omitted.

​

​

Section 11. Miscellaneous.

​

(a)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 D Preferred Stock granted hereunder may be waived as to all shares of Series D Preferred Stock (and the Holders thereof) upon the written consent of the Holders of a majority of the shares of Series D Preferred Stock then outstanding, unless a higher percentage is required by the DGCL, in which case the written consent of the Holders of not less than such higher percentage shall be required.

​

(b)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.

​

(c)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.

​

(d)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.

​

(e)Status of Converted Series D Preferred Stock. If any shares of Series D Preferred Stock shall be converted or redeemed by the Corporation, such shares shall resume the status of authorized but unissued shares of preferred stock and shall no longer be designated as Series D Preferred Stock.

​

7. Release by Holder. In consideration of the foregoing, each Holder releases and discharges Company, Company’s officers, directors, principals, control persons, past and present employees, insurers, successors, and assigns (“Company Parties”) from all actions, cause of action, suits, debts, dues, sums of money, accounts, reckonings, bonds, bills, specialties, covenants, contracts, controversies, agreements, promises, variances, trespasses, damages, judgments, extents, executions, claims, and demands whatsoever, in law, admiralty or equity, which against Company Parties ever had, now have or hereafter can, shall or may, have for, upon, or by reason of any matter, cause or thing whatsoever, whether or not known or unknown, arising under the Exchange Securities.
