Note 2. Summary of Significant Accounting Policies

Basis of presentation

The unaudited consolidated financial statements include the accounts of CytoDyn Inc. and its wholly owned subsidiary, CytoDyn Operations Inc. All intercompany transactions and balances are eliminated in consolidation. The consolidated financial statements reflect all normal recurring adjustments which are, in the opinion of management, necessary for a fair statement of the results of operations for the interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP” or “GAAP”) have been omitted in accordance with the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The interim financial information and notes thereto should be read in conjunction with the Company's latest Annual Report on Form 10-K for the fiscal year ended May 31, 2024, as amended by Amendment No. 1 on Form 10-K/A (the “2024 Form 10-K”). The results of operations for the periods presented are not necessarily indicative of results to be expected for the entire fiscal year or for any other future annual or interim period.

Going concern

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. As presented in the accompanying consolidated financial statements, the Company had losses for all periods presented, except for the current period. The Company has an accumulated deficit of approximately $872.3 million as of August 31, 2024. These factors, among others, including the various matters discussed in Note 9, Commitments and Contingencies, raise substantial doubt about the Company’s ability to continue as a going concern. The consolidated financial statements do not include any adjustments relating to the recoverability of assets and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

The Company’s continuance as a going concern is dependent upon its ability to obtain additional operating capital, complete the development of its product candidate, leronlimab, obtain approval to commercialize leronlimab from regulatory agencies, continue to outsource manufacturing of leronlimab, and ultimately generate revenues and attain profitability. The Company plans to continue to engage in research and development activities related to leronlimab and a new or modified longer-acting therapeutic for multiple indications and expects to incur significant research and

development expenses in the future, primarily related to its regulatory compliance, including performing additional pre-clinical and clinical studies in various indications, and seeking regulatory approval for its product candidate for commercialization. These research and development activities are subject to significant risks and uncertainties. The Company intends to finance its future development activities and its working capital needs primarily from the sale of equity and debt securities, combined with additional funding from other sources. However, there can be no assurance that the Company will be successful in these endeavors.

Use of estimates

The unaudited consolidated financial statements have been prepared in accordance with GAAP, which requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, and the disclosure of contingent assets and liabilities at the date of consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Estimates are assessed each period and updated to reflect current information, such as the status of our analysis of the results of our clinical trials and/or discussions with the U.S. Food and Drug Administration (“FDA”), which could have an impact on the Company’s significant accounting estimates and assumptions. The Company’s estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Significant estimates include, but are not limited to, those relating to stock-based compensation, the assumptions used to value warrants and warrant modifications. Actual results could differ from these estimates.

Restricted cash

As of August 31, 2024, the Company had no restricted cash. The restricted cash in the prior period was related to cash that was being held as collateral in connection with a surety bond that was posted as required in the Amarex Clinical Research L.L.C. (“Amarex”) litigation and was released in full on July 2, 2024, as part of the settlement agreement.

Fair value of financial instruments

In accordance with the prescribed accounting guidance, the Company measured fair value of derivative instruments using fair value hierarchy which include:

Level 1. Quoted prices in active markets for identical assets or liabilities.

Recent Accounting Pronouncements

In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-06, Disclosure Improvements – Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. The amendments clarify or improve disclosure and presentation requirements on various disclosure areas, including the statement of cash flows, earnings per share, debt, equity, and derivatives. The amendments will align the requirements in the FASB Accounting Standards Codification (“ASC”) with the SEC’s regulations. The amendments in this ASU will be effective on the date the related disclosures are removed from

Regulation S-X or Regulation S-K by the SEC and will not be effective if the SEC has not removed the applicable disclosure requirement by June 30, 2027. Early adoption is prohibited. The Company is currently evaluating the impact of the amendments on its financial statement disclosures.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). The standard is intended to improve annual and interim reportable segment disclosure requirements regardless of the number of reporting units, primarily through enhanced disclosure of significant expenses. The amendment requires public entities to disclose significant segment expenses that are regularly provided to the CODM and included with each reported measure of segment profit and loss. The standard is effective for annual periods beginning after December 15, 2023. Early adoption is permitted and the amendments in this update should be applied retrospectively to all periods presented. The Company is currently evaluating the impact of this update on its financial statement disclosures but does not believe it will materially impact the financial statements.

On December 14, 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures, which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. The ASU is effective for annual periods beginning after December 15, 2024, and allows for adoption on a prospective basis, with a retrospective option. The Company is currently evaluating the effect of this update on its consolidated financial statements and related disclosures.
