Acasti Pharma Schedules Conference Call for August 4th at 1:00 PM ET to Discuss Planned Acquisition of Grace Therapeutics

All shareholders are strongly encouraged to vote in advance of the August 26, 2021, annual and special meeting of shareholders

LAVAL, Québec, July 23, 2021 (GLOBE NEWSWIRE) — Acasti Pharma Inc. (“Acasti” or the “Company”) (Nasdaq: ACST and TSX-V: ACST) announces it will host a business update conference call on Wednesday, August 4^th at 1:00 PM ET to discuss the planned acquisition of Grace Therapeutics, Inc. (“Grace”), a privately held emerging biopharmaceutical company focused on developing innovative drug delivery technologies for the treatment of rare and orphan diseases.

Acasti plans to provide additional context on the proposed Grace acquisition and its benefits, including Grace’s:

• diversified drug pipeline with multiple, high quality clinical assets;
• significant addressable market opportunities;
• three clinical stage assets with a potentially shorter timeline to key milestones;
• efficient and lower-cost clinical and regulatory pathway;
• and a strong and growing intellectual property portfolio.

Additionally, management plans to discuss how this acquisition represents a unique opportunity for Acasti and its shareholders to build a new, late-stage specialty pharma company focused on rare diseases, by combining Acasti’s extensive drug development, manufacturing, commercialization capabilities and strong balance sheet with Grace’s drug delivery technologies and deep product pipeline. Following the merger, Acasti expects to have more than $60 million in cash, which should provide at least two years of operating runway and enable the Company to deliver meaningful catalysts including the completion of development and NDA filing for GTX-104, Grace’s lead clinical asset, as well as advance other drug candidates in the Grace pipeline to key, value-enhancing milestones.

Acasti strongly encourages all investors to vote in advance of the August 26, 2021 annual and special meeting of shareholders, in order to ensure the quorum requirements are met to approve the transaction. In order for shares to be voted at the annual and special meeting, a proxy must be received (whether delivered by mail, telephone or internet) by no later than 5:00 p.m. Eastern Time on August 24, 2021 by Acasti’s registrar and transfer agent, Computershare Investor Services Inc., Attention: Proxy Department, 100 University Avenue, 9th Floor, Toronto, Ontario, M5J 2Y1, telephone number: 1-866-732-VOTE (8683), website: www.investorvote.com.

Cautionary Statement Regarding Forward-Looking Statements

These statements may discuss goals, intentions and expectations as to future plans, trends, events, results of operations or financial condition, or otherwise, based on current beliefs of the management of Acasti, as well as assumptions made by, and information currently available to, management. Forward-looking statements generally include statements that are predictive in nature and depend upon or refer to future events or conditions, and include words such as “may,” “will,” “should,” “would,” “expect,” “estimate,” “plan,” “believe,” “anticipate,” “intend,” “look forward,” and other similar expressions among others. Statements that are not historical facts are forward-looking statements. Forward-looking statements are based on current beliefs and assumptions that are subject to risks and uncertainties and are not guarantees of future performance.

Forward-looking statements contained in this document may include, without limitation, statements regarding the proposed merger between Acasti and Grace; the timing and financial and strategic benefits thereof; the expected impact of the transaction on the cash balance of Acasti following the merger; Acasti’s future strategy, plans and expectations after the merger; and the anticipated timing of clinical trials and approvals for, and the commercial potential of, Acasti’s products and pipeline product candidates and those of its subsidiaries (including Grace, if the merger is completed). Actual results could differ materially from those contained in any forward-looking statement as a result of various factors, including the failure to receive, on a timely basis or otherwise, the required approvals by Acasti shareholders or Grace stockholders, as applicable, in connection with the merger; the risk that a condition to closing of the merger may not be satisfied; the possibility that the anticipated benefits of the proposed merger may not be fully realized or may take longer to realize than expected; the possibility that costs or difficulties related to the integration of the businesses of Acasti and Grace will be greater than expected; the ability of the companies following the merger to commercialize drug candidates in line with the companies’ expectations; the ability to retain and hire key personnel and maintain relationships with customers, key opinion leaders, suppliers or other business partners; the impact of legislative, regulatory, competitive and technological changes; and other risk factors relating to the companies’ businesses and the biopharmaceutical industry, as detailed from time to time in Acasti’s reports filed with the SEC and the Canadian Securities Administrators, which you are encouraged to review. Investors should not place undue reliance on forward-looking statements.

For a discussion of the factors that may cause Acasti’s, Grace’s or the combined company’s actual results, performance or achievements to differ materially from any future results, performance or achievements expressed or implied in such forward-looking statements, and for a discussion of risks associated with the ability of Acasti and Grace to complete the merger and the effect of the merger on the business of Acasti, Grace and the combined company, see the section titled “Risk Factors” in the prospectus / proxy statement.

The forward-looking statements reflect management’s current knowledge, assumptions, beliefs, estimates and expectations and express management’s current view of future performance, results and trends. If any of these risks or uncertainties materializes or any of these assumptions proves incorrect, the results of Acasti, Grace or the combined company could differ materially from the forward-looking statements. All forward-looking statements in this document are current only as of the date on which the statements were made, or in the case of a document incorporated by reference, as of the date of that document. Except as required by applicable law, neither Acasti nor Grace undertakes any obligation to update publicly any forward-looking statements for any reason after the date of this document or to conform these statements to actual results or to changes in expectations.
