Item 3.03. Material Modifications of Rights of Security Holders.

To the extent required by Item 3.03 of Form 8-K, the information contained in Item 5.03 herein is incorporated by reference into this Item 3.03.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

At the Moleculin Biotech, Inc. (the “Company”) special meeting of stockholders completed on October 3, 2023, the stockholders of the Company approved an amendment to the Company’s amended and restated certificate of incorporation (the “Amendment”) to effect the reverse stock split at a ratio in the range of 1-for-5 to 1-for-20, with such ratio to be determined in the discretion of the Company’s board of directors and with such reverse stock split to be effected at such time and date, if at all, as determined by the Company’s board of directors in its sole discretion prior to the one-year anniversary of the special meeting.

Pursuant to such authority granted by the Company’s stockholders, the Company’s board of directors approved a one-for-fifteen (1:15) reverse stock split (the “Reverse Stock Split”) of the Company’s common stock and the filing of the Amendment to effectuate the Reverse Stock Split. The Amendment was filed with the Secretary of State of the State of Delaware and the Reverse Stock Split will become effective in accordance with the terms of the Amendment at 11:59 p.m. Eastern Time on March 21, 2024 (the “Effective Time”), and the Company’s common stock will open for trading on The Nasdaq Capital Market on March 22, 2024 on a post-split basis, under the existing ticker symbol “MBRX” but with a new CUSIP number 60855D309. The Amendment provides that, at the Effective Time, every fifteen shares of the Company’s issued and outstanding common stock will automatically be combined into one issued and outstanding share of common stock, without any change in par value per share, which will remain $0.001.

As a result of the Reverse Stock Split, the number of shares of common stock outstanding will be reduced from approximately 33.4 million shares to approximately 2.2 million shares, and the number of authorized shares of common stock will remain at 100 million shares. As a result of the Reverse Stock Split, proportionate adjustments will be made to the per share exercise price and/or the number of shares issuable upon the exercise or vesting of all outstanding stock options, restricted stock unit awards and warrants, which will result in a proportional decrease in the number of shares of the Company’s common stock reserved for issuance upon exercise or vesting of such stock options, restricted stock unit awards and warrants, and, in the case of stock options and warrants, a proportional increase in the exercise price of all such stock options and warrants. In addition, the number of shares reserved for issuance under the Company’s equity compensation plan immediately prior to the Effective Time will be reduced proportionately.

No fractional shares will be issued as a result of the Reverse Stock Split. Stockholders of record who would otherwise be entitled to receive a fractional share will be entitled to the rounding up of the fractional share to the nearest whole number. 

The summary of the of Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment, a copy of which is attached hereto as Exhibit 3.1 and is incorporated herein by reference.
