Item 3.03         Material Modifications to Rights of Security Holders.

To the extent required by Item 3.03 of Form 8-K, the information regarding the Reverse Stock Split (as defined below) contained in Item 5.03 of this Current Report on Form 8-K is incorporated by reference herein.

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

On February 23, 2023, Windtree Therapeutics, Inc. (the “Company”) announced that it intends to effect a reverse stock split (the “Reverse Stock Split”) of its issued and outstanding shares of common stock, par value $0.001 per share (the “Common Stock”) at a ratio of 1 post-split share for every 50 pre-split shares. The Common Stock will continue to be traded on the Nasdaq Capital Market under the symbol “WINT” and will begin trading on a split-adjusted basis when the market opens on Friday, February 24, 2023, under a new CUSIP number, 97382D 402.

At a special meeting of stockholders held on February 7, 2023, the Company’s stockholders granted the Company’s Board of Directors (the “Board”) the discretion to effect a reverse stock split of the Common Stock through an amendment (the “Amendment”) to the Company’s Amended and Restated Certificate of Incorporation at a ratio of any whole number between 1-for-20 and 1-for-50, with such ratio to be determined by the Board.

On February 22, 2023, the Company filed the Amendment for the Reverse Stock Split 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 12:01 AM Eastern Time on February 24, 2023 (the “Effective Time”).

At the Effective Time, every 50 shares of the Company’s issued and outstanding Common Stock will be converted automatically into one issued and outstanding share of Common Stock, but without any change in the par value per share. Proportional adjustments will be made to the number of shares of Common Stock issuable upon exercise of the Company’s outstanding stock options, RSUs and warrants, as well as the applicable exercise price.

Continental Stock Transfer & Trust Company is acting as transfer and exchange agent for the Reverse Stock Split. Stockholders who hold their shares in book-entry form or in “street name” (through a broker, bank or other holder of record) are not required to take any action. The Reverse Stock Split will affect all stockholders uniformly and will not alter any shareholder’s percentage interest in the Company’s equity, except to the extent that the Reverse Stock Split would result in a shareholder owning a fractional share. No fractional shares will be issued in connection with the Reverse Stock Split. Stockholders who would otherwise be entitled to receive a fractional share will instead receive one whole share of Common Stock in lieu of any fractional share.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment, which is filed as Exhibit 3.1 to this Current Report on Form 8-K and incorporated by reference herein.
