Note 1 Business Description and Basis of Presentation

Business

Anavex Life Sciences Corp. (“Anavex” or the “Company”) is a clinical stage biopharmaceutical company engaged in the development of differentiated therapeutics by applying precision medicine to central nervous system (“CNS”) diseases with high unmet need. Anavex analyzes genomic data from clinical trials to identify biomarkers, which are used in the analysis of its clinical trials for the treatment of neurodegenerative and neurodevelopmental diseases.

The Company’s focus is on developing innovative treatments for Alzheimer’s disease, Parkinson’s disease, schizophrenia, neurodevelopmental, neurodegenerative, and rare diseases, including Rett syndrome, and other central nervous system (CNS) disorders.

Basis of Presentation

These consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and the instructions to Form 10-K and have been prepared under the accounting principles generally accepted in the United States of America (“U.S. GAAP”).

Certain immaterial amounts from prior periods have been reclassified to conform to the current year’s presentation.

Liquidity

All of the Company’s potential drug compounds are in the clinical development stage and the Company cannot be certain that its research and development efforts will be successful or, if successful, that its potential drug compounds will ever be approved for sales to pharmaceutical companies or generate commercial revenues. To date, the Company has not generated any revenue from our operations. The Company expects the business to continue to experience negative cash flows from operations for the foreseeable future and cannot predict when, if ever, its business might become profitable.

Management believes that the current working capital position will be sufficient to meet the Company’s working capital requirements beyond the next 12 months after the date that these consolidated financial statements are issued. The process of drug development can be costly, and the timing and outcomes of clinical trials are uncertain. The assumptions upon which the Company has based its estimates are routinely evaluated and may be subject to change. The actual amount of the Company’s expenditures will vary depending upon a number of factors including but not limited to the design, timing and duration of future clinical trials, the progress of the Company’s research and development programs and the level of financial resources available. The Company has the ability to adjust its operating plan spending levels based on the timing of future clinical trials.

Other than our rights related to the 2025 Sales Agreement and the 2023 Purchase Agreement (as defined below in Note 5), there can be no assurance that additional financing will be available when needed or, if available, that it can be obtained on commercially reasonable terms. The Company will need to file a prospectus supplement in order to access funds under the 2023 Purchase Agreement. If the Company is not able to obtain the additional financing on a timely basis, if and when it is needed, it will be forced to delay or scale down some or all of its research and development activities.
