1. NATURE AND CONTINUANCE OF OPERATIONS

Bright Minds Biosciences Inc. (the "Company") was incorporated under the Business Corporations Act of British Columbia on May 31, 2019. The Company's objective is to generate income and achieve long term profitable growth through the development of therapeutics to improve the lives of patients with certain severe and life-altering diseases. On November 8, 2021, the Company started trading on the NASDAQ under the symbol "DRUG". The registered address of the Company is located at 1500 - 1055 West Georgia Street, Vancouver, British Columbia, V6E 4N7, Canada. The head office address of the Company is located at 19 Vestry Street, New York, NY 10013, USA.

These consolidated financial statements have been prepared on a going concern basis which assumes that the Company will be able to realize its assets and discharge its liabilities in the normal course of business for the foreseeable future. As at December 31, 2025, the Company is not able to finance day to day activities through operations and has comprehensive loss of $7,565,318 for three months ended December 31, 2025 (2024 - $49,610 net income). The Company has a deficit of $54,143,635 since inception and negative operating cash flows. As at December 31, 2025, the Company has working capital of $89,205,114 (September 30, 2025 - $81,974,204). The continuing operations of the Company are dependent upon its ability to attain profitable operations and generate funds therefrom. Management intends to finance operating costs with equity financings, loans from directors and companies controlled by directors and/or private placement of common shares.

2. STATEMENT OF COMPLIANCE AND BASIS OF PREPARATION

Statement of compliance

The Company applies IFRS Accounting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB"). These unaudited condensed interim consolidated financial statements have been prepared in accordance with International Accounting Standard 34 - Interim Financial Reporting. Accordingly, they do not include all of the information required for full annual financial statements required by IFRS as issued by the IASB. The policies applied in these unaudited condensed interim consolidated financial statements are based on IFRSs issued and outstanding as of February 12, 2026, the date the Board of Directors approved the statements. The same accounting policies and methods of computation are followed in these unaudited condensed interim consolidated financial statements as compared with the most recent annual financial statements as at and for the year ended September 30, 2025 except as noted below. Any subsequent changes to IFRS that are given effect in the Company's annual financial statements for the year ending September 30, 2026 could result in restatement of these unaudited condensed interim consolidated financial statements.

Basis of preparation

Depending on the applicable IFRS requirements, the measurement basis used in the preparation of these condensed interim consolidated financial statements is cost, net realizable value, fair value or recoverable amount. These condensed interim consolidated financial statements, except for the statement of cash flows, are based on the accrual basis.

3. MATERIAL ACCOUNTING POLICY INFORMATION

Basis of consolidation

These consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries Bright Minds Biosciences LLC, a Delaware limited liability company, and Bright Minds Bioscience Pty Ltd., a proprietary company registered under the Corporations Act of Australia on June 24, 2021. On June 10, 2021, the Chief Executive Officer of the Company transferred, assigned and conveyed all of his membership interests in Bright Minds Biosciences LLC to the Company.

A subsidiary is an entity that the Company controls, either directly or indirectly, where control is defined as the power to govern the financial and operating policies of an entity so as to obtain benefits from its activities. The financial results of the Company's subsidiaries are included in the consolidated financial statements from the date that control commences until the date that control ceases. The accounting policies of the Company's subsidiaries have been aligned with the policies adopted by the Company. When the Company ceases to control a subsidiary, the financial statements of that subsidiary are de-consolidated.

Inter-company balances and transactions, and any income and expenses arising from inter-company transactions, have been eliminated in these consolidated financial statements.

Significant accounting estimates

The preparation of the consolidated financial statements in conformity with IFRS requires management to make estimates, judgments and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected.

Certain of the Company's accounting policies and disclosures require key assumptions concerning the future and other estimates that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities or disclosures within the next fiscal year. Where applicable, further information about the assumptions made is disclosed in the notes specific to that asset or liability. The significant accounting estimates and judgments set out below have been applied consistently to all periods presented in these consolidated financial statements.

Ability to continue as a going concern

Evaluation of the ability of the Company to realize its strategy for funding its future needs for working capital involves making judgments.

Share-based compensation

The fair value of stock options is measured using a Black Scholes option pricing model. Measurement inputs include the common share price on the grant date, the exercise price of the instrument, the expected common share price volatility, the weighted average expected life of the instruments, the expected dividends and the risk-free interest rate. Service and non-market performance conditions are not taken into account in determining fair value. The fair value of equity settled Restricted Share Units ("RSUs") is measured based on management's best estimate of the Company's share price on the grant date.

The share-based compensation recognized is also determined based on management's grant date estimate of the forfeitures that are expected to occur over the life of the stock options and equity settled RSUs. Cash settled RSUs outstanding are fair valued using a mark-to-market calculation based on the Company's closing common share price at the end of the period. The number of stock options and RSUs that actually vest could differ from the estimated number of awards expected to vest and any differences between the actual and estimated forfeitures are recognized prospectively as they occur.

3. MATERIAL ACCOUNTING POLICY INFORMATION (continued)

Foreign currency translation

The functional currency of the Company, Bright Minds Biosciences LLC and Bright Minds Bioscience Pty Ltd. is the Canadian dollar and the presentation currency of the Company is the Canadian dollar. Transactions in currencies other than the functional currency are recorded at the rates of exchange prevailing on the transaction date. Monetary assets and liabilities that are denominated in foreign currencies are translated at the rates prevailing at each reporting date. Non-monetary assets and liabilities denominated in foreign currencies that are measured at fair value are retranslated to the functional currency at the exchange rate at the date the fair value was determined. Non-monetary items that are measured in terms of historical cost in a foreign currency are not retranslated. Foreign currency translation differences are recognized in profit or loss.

Please refer to Note 3 of the audited consolidated financial statements of the company for the year ended September 30, 2025 for full disclosure of the material accountability policy information.

Accounting Standards, Amendments and Interpretations

The following amendments were adopted by the Company:

a) Disclosure of Accounting Policies (Amendments to IAS 1 and IFRS Practice Statement 2) - the amendments require that an entity discloses its material accounting policies, instead of its significant accounting policies. Further amendments explain how an entity can identify a material accounting policy.

b) Definition of Accounting Estimates (Amendments to IAS 8) - the amendments replace the definition of a change in accounting estimates with a definition of accounting estimates. Under the new definition, accounting estimates are "monetary amounts in consolidated financial statements that are subject to measurement uncertainty". Entities develop accounting estimates if accounting policies require items in consolidated financial statements to be measured in a way that involves measurement uncertainty. The amendments clarify that a change in accounting estimate that results from new information or new developments is not the correction of an error.

There was no impact on the Company's condensed interim consolidated financial statements upon the adoption of these amendments.

Accounting Pronouncements Not Yet Adopted

IFRS 18, Presentation and Disclosure in Financial Statements, which will replace IAS 1, Presentation of Financial Statements aims to improve how companies communicate in their financial statements, with a focus on information about financial performance in the statement of profit or loss, in particular additional defined subtotals, disclosures about management-defined performance measures and new principles for aggregation and disaggregation of information. IFRS 18 is accompanied by limited amendments to the requirements in IAS 7 Statement of Cash Flows. IFRS 18 is effective from January 1, 2027. Companies are permitted to apply IFRS 18 before that date.

In January 2020, the IASB issued amendments to IAS 1, Presentation of Financial Statements, to provide a more general approach to the presentation of liabilities as current or non current based on contractual arrangements in place at the reporting date.

specify that the rights and conditions existing at the end of the reporting period are relevant in determining whether the Company has a right to defer settlement of a liability by at least twelve months;

provide that management's expectations are not a relevant consideration as to whether the Company will exercise its rights to defer settlement of a liability; and

clarify when a liability is considered settled.
