Princeton, NJ, September 26, 2023 (GLOBE NEWSWIRE)-- Acasti Pharma Inc. (Nasdaq: ACST) (Acasti or the Company), a late-stage, biopharma company advancing GTX-104, its novel formulation of nimodipine that addresses the high unmet medical needs for a rare disease, aneurysmal subarachnoid hemorrhage (aSAH), today announced that it has closed a private placement of the Company's securities pursuant to the terms of a securities purchase agreement, dated September 24, 2023, by and between the Company and certain institutional and accredited investors (the “Purchase Agreement”). Pursuant to the terms of the Purchase Agreement, the Company issued and sold an aggregate of 1,951,371 common shares, no par value per share, pre-funded warrants (the “Pre-funded Warrants”) to purchase up to an aggregate of 2,106,853 common shares, each at a purchase price of $1.8481 per common share or Pre-funded Warrant (less $0.0001 per Pre-funded Warrant) and accompanying common warrants (the “Common Warrants”) to purchase up to an aggregate of 2,536,391 common shares, in a private placement priced at-the-market under Nasdaq rules. The private placement closed on September 25, 2023.

Each Pre-funded Warrant is exercisable for one common share at an exercise price of $0.0001 per common share, will be immediately exercisable and will expire once exercised in full. Each Common Warrant is exercisable for one common share at an exercise price of $3.003 per common share, will be immediately exercisable and will expire on the earlier of (i) the 60th day after the date of the acceptance by the U.S. Food and Drug Administration (“FDA”) of a New Drug Application for the Company's product candidate GTX-104 or (ii) five years from the date of issuance.

The offer and sale of the foregoing securities in the private placement were made in a transaction not involving a public offering under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”) and/or Rule 506(b) of Regulation D promulgated thereunder, and such securities have not been registered under the Securities Act or applicable state securities laws. Accordingly, the securities in the private placement may not be reoffered or resold in the United States except pursuant to an effective registration statement with the Securities and Exchange Commission (the “SEC”) or an applicable exemption from the registration requirements of the Securities Act and such applicable state securities laws.

The Company has agreed to file an initial registration statement with the SEC covering the resale of the common shares and the common shares underlying the Pre-funded Warrants and Common Warrants issued in the private placement no later than 30 days following the closing date of the private placement.

The gross proceeds to the Company from the private placement were approximately $7.5 million, before deducting fees and expenses. The Company currently intends to use the net proceeds from the private placement for clinical trial expenses to further the Phase 3 clinical trial for GTX-104, the Company's lead product candidate, pre-commercial planning, working capital and other general corporate purposes.

This press release shall not constitute an offer to sell or a solicitation of an offer to buy these securities, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or jurisdiction.
