Neuren Pharmaceuticals Annual Report 2023

1. NATURE OF BUSINESS Neuren Pharmaceuticals Limited (Neuren or the Company, and its subsidiaries, or the Group) is a publicly listed biopharmaceutical company developing drugs for neurological disorders. The Company is a limited liability company incorporated in New Zealand. The address of its registered office in New Zealand is at the offices of Lowndes Jordan, Level 15 HSBC Tower, 188 Quay Street, Auckland 1141. Neuren ordinary shares are listed on the Australian Securities Exchange (ASX code: NEU). These consolidated financial statements have been approved for issue by the Board of Directors on 29 February 2024. Material Uncertainties – The Group’s licensing and research and development activities involve inherent risks. These risks include, among others: dependence on the sales made by licensees, the Group’s ability to retain key personnel; the Group’s ability to protect its intellectual property and prevent other companies from using the technology; part of the Group’s business is based on novel and yet to be proven technology; the Group’s ability to sufficiently complete the clinical trials process; and technological developments by the Group’s competitors could render its products obsolete. – The Group’s revenue from licence agreements includes quarterly royalty income contingent on the amount of ongoing sales, whilst other milestone payments are contingent on future sales and events and will be intermittent. The business plan therefore may require expenditure in excess of revenue and in the future the Group may need to raise further financing through other public or private equity financings, collaborations or other arrangements with corporate sources, or other sources of financing to fund operations. There can be no assurance that such additional financing, if available, can be obtained on terms reasonable to the Group. 2.

Critical accounting estimates The preparation of financial statements requires the use of certain critical accounting estimates.

The areas involving a higher degree of judgement or complexity, or areas where assumptions and estimates are significant to the financial statements are disclosed in Note 19. Going concern basis The directors monitor the Group’s cash position and initiatives to ensure that adequate funding continues to be available for the Group to meet its business objectives. The Group recorded a profit after tax of $157.0 million for the year ending 31 December 2023 and had positive operating cash flows of $184.9 million for the year ended 31 December 2023. The Group had cash of $17.1 million and short-term investments (term deposits) of $211.5 million at 31 December 2023.
