Management Discussion

Prashant Kohli, Chief Executive Officer of Acasti, said, After receiving positive clarifying feedback from the FDA on the proposed Phase 3 Safety Study for GTX-104 whereby they concurred with the suitability of the 505(b)(2) regulatory pathway and that Acasti's GTX-104-002 PK study may have met the criteria for a scientific bridge, we moved swiftly to submit the full protocol for our pivotal Phase 3 Safety Study in May 2023. Further, we implemented a strategic realignment plan to maximize shareholder value, including a strategic transformation of Acasti's operating model to that of an agile biopharma company which we believe allows our cash runway to be sufficient to achieve a potential NDA filing for GTX-104 in 2025. Our new, highly motivated, and energized organization is entirely focused on achieving critical value inflection milestones in the quarters and years to come.

FY 2023 Financial Results

The Company's consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America and are presented in U.S. dollars.

Research and development expenses, net of government assistance for the twelve months ended March 31, 2023, totaled $9.9 million compared to $5.6 million for the twelve months ended March 31, 2022. Our research and development during the year ended March 31, 2023 was focused primarily on three clinical development programs GTX-104, GTX-102, and GTX-101 drug candidates. Due to the strategic realignment announced on April 4, 2023, the Company will focus its future research and development expenses exclusively on GTX-104. Future development of GTX-102 and GTX-101 will depend on additional dedicated funding or the signing of a strategic partnership. Research and development expenses during the year ended March 31, 2022, related to the completion of our TRILOGY Phase 3 clinical program for our former drug candidate CaPre, as well as the initiation and progression of development work related to GTX-104, GTX-102 and GTX-101.

General and administrative expenses for the twelve months ended March 31, 2023 were $7.6 million compared to $9.3 million for the twelve months ended March 31, 2022. The decrease was primarily a result of decreased legal, tax, accounting and other professional fees related to the Grace merger for the year ended March 31, 2022. Due to the strategic realignment announced on April 4, 2023, the Company is over time discontinuing its operations in Canada and has proceeded to lay off substantially all its workforce, allowing Acasti's new management team to rebuild a leaner organization in the United States.

As a result of the strategic realignment plan announced on April 4, 2023 to prioritize resources to GTX-104, and away from GTX-101 and GTX-102, the company incurred an impairment of intangible assets of $28.7 million, and an impairment of goodwill of $4.8 million, for the period ended March 31, 2023.

Loss from operating activities for the twelve months ended March 31, 2023 was $52.1 million compared to a loss of $15.6 million for the twelve months ended March 31, 2022. The change is primarily a result of the combined $33.5 million impairments to intangible assets and goodwill mentioned.

For the twelve months ended March 31, 2022, a financial gain of $5.1 million resulted mostly due to the decrease in the fair value of the derivative warrant liabilities.

Net loss and total comprehensive loss for the twelve months ended March 31, 2023 was $(42.4) million, or $(0.95) loss per share, compared to a net loss of $(9.8) million, or $(0.27) income per share, for the twelve months ended March 31, 2022. The change is primarily a result of the combined $33.5 million impairments to intangible assets and goodwill mentioned.

Cash, cash equivalents and short-term investments totaled $27.9 million as of March 31, 2023, compared to $43.7 million in cash, cash equivalents and short-term investments as of March 31, 2022. Based on management's current projections, current cash, cash equivalents and short-term investments are expected to be sufficient to fund the Company through calendar Q2 2025, facilitating achievement of critical value inflection milestones, including a potential New Drug Application (NDA) filing for GTX-104.

Acasti is a late-stage biopharma company with drug candidates addressing rare and orphan diseases. Acasti's novel drug delivery technologies have the potential to improve the performance of currently marketed drugs by achieving faster onset of action, enhanced efficacy, reduced side effects, and more convenient drug delivery. Acasti's lead clinical assets have each been granted Orphan Drug Designation by the FDA, which provides seven years of marketing exclusivity post-launch in the United States, and additional intellectual property protection with over 40 granted and pending patents. Acasti's lead clinical asset, GTX-104, is an intravenous infusion targeting aneurysmal Subarachnoid Hemorrhage (aSAH), a rare and life-threatening medical emergency in which bleeding occurs over the surface of the brain in the subarachnoid space between the brain and skull.
