WARRINGTON, Pa., July 22, 2024 (GLOBE NEWSWIRE) -- Windtree Therapeutics, Inc. (“Windtree” or “the Company”) (NasdaqCM: WINT), a biotechnology company focused on advancing early and late-stage innovative therapies for critical conditions and diseases, today announced the closing of a private placement of (i) 16,099 shares of the Company’s Series C Convertible Preferred Stock, $0.001 par value (the “Series C Preferred Stock”), and (ii) warrants (the “Warrants”) to acquire up to the aggregate number of 3,440,631 additional shares of the Company’s common stock, $0.001 par value per share (the “Common Stock”), for aggregate gross proceeds of approximately $12.9 million, including $9.5 million through the cancellation and extinguishment of certain holders’ (x) outstanding (i) 10% senior convertible notes due January 2025, (ii) senior secured notes due June 2025, (iii) senior unsecured promissory notes due July 2025, and (iv) senior secured notes due July 2025, and (y) 5,500 shares of the Company’s Series B Convertible Preferred Stock. The Warrants will have an exercise price of $4.11 per share, subject to customary adjustments, will become exercisable on the six month and one day anniversary of the issuance date (the “Initial Exercisability Date”), and expire on the fifth anniversary of the Initial Exercisability Date. The Company filed a Current Report on Form 8-K with the Securities and Exchange Commission on July 22, 2024, with additional details of the transaction. The Company agreed to seek stockholder approval for the issuance of all of the shares of Common Stock issuable upon conversion of the Series C Preferred Stock and exercise of the Warrants in accordance with the rules and regulations of the Nasdaq Stock Market. The Company intends to use the gross proceeds from the private placement for working capital and general corporate purposes. Kingswood Capital Partners, LLC acted as placement agent for the transaction.

Additionally, on June 26, 2024, Windtree entered into a Common Stock Purchase Agreement with an equity line investor (the “Purchaser”), whereby the Company has the right, but not the obligation, to sell to the Purchaser, and, subject to limited exceptions, the Purchaser is obligated to purchase, up to $35 million of newly issued shares of the Company’s common stock. The Company does not have a right to commence any sales of Common Stock to the Purchaser until the time when all of the conditions to the Company’s right to commence sales of Common Stock to the Purchaser set forth in the Purchase Agreement have been satisfied, including that a registration statement covering the resale of such shares is declared effective by the SEC and the final form of prospectus contained therein is filed with the SEC. Actual sales of shares of Common Stock to the Purchaser under the Purchase Agreement will depend on a variety of factors to be determined by the Company from time to time, including, among others, market conditions, the trading price of the Common Stock and determinations by the Company as to the appropriate sources of funding and the Company’s operations.

“We are pleased to announce this private placement and the equity line of credit as they accomplish several important objectives for the company,” said Craig Fraser, CEO. “First, the private placement delivers needed capital to support company operations, including the active Phase 2b clinical trial for istaroxime in cardiogenic shock. Second, the transaction fully converted and eliminated senior notes, including senior secured notes we used as bridge financing over the past several months eliminating this debt from our balance sheet.” Mr. Fraser further added, “Looking forward, the Phase 2b clinical trial in early cardiogenic shock is planned to complete enrollment in the next several weeks and report topline data by the end of this quarter. The equity line of credit, as well as the warrants that came with each newly issued share in the private placement, could potentially be utilized as additional sources of capital to fund continued development of our portfolio.”
