Organization and Basis of Presentation	1. Organization and Basis of Presentation The condensed consolidated financial statements of Lixte Biotechnology Holdings, Inc., a Delaware corporation), including its wholly-owned Delaware subsidiary, Lixte Biotechnology, Inc. (collectively, the “Company”), at June 30, 2024, and for the three months and six months ended June 30, 2024 and 2023, are unaudited. In the opinion of management of the Company, all adjustments, including normal recurring accruals, have been made that are necessary to present fairly the financial position of the Company as of June 30, 2024, and the results of its operations for the three months and six months ended June 30, 2024 and 2023, and its cash flows for the six months ended June 30, 2024 and 2023. Operating results for the interim periods presented are not necessarily indicative of the results to be expected for a full fiscal year. The condensed consolidated balance sheet at December 31, 2023 has been derived from the Company’s audited consolidated financial statements at such date. The condensed consolidated financial statements and related notes have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the financial statements and other information included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, as filed with the SEC. *Business* The Company is a clinical-stage biopharmaceutical company focused on identifying new targets for cancer drug development and developing and commercializing cancer therapies. The Company’s corporate office is located in Pasadena, California.

The Company believes that inhibitors of protein phosphatases have significant therapeutic potential for a broad range of cancers. The Company is focusing on the clinical development of a specific protein phosphatase inhibitor, referred to as LB-100, which has been shown to have clinical anti-cancer activity at doses that produce little or no toxicity.

In addition, Nasdaq has other continued listing requirements, one of which is maintaining a minimum net stockholders’ equity of $2,500,000.

Because the Company is currently engaged in various early-stage clinical trials, it is expected that it will take a significant amount of time and resources to develop any product or intellectual property capable of generating sustainable revenues. Accordingly, the Company’s business is unlikely to generate any sustainable operating revenues in the next several years and may never do so. Even if the Company is able to generate revenues through licensing its technology, product sales or other commercial activities, there can be no assurance that the Company will be able to achieve and maintain positive earnings and operating cash flows. At June 30, 2024, the Company’s remaining financial contractual commitments pursuant to clinical trial agreements and clinical trial monitoring agreements not yet incurred aggregated approximately $3,614,000 (see Note 8), which are currently scheduled to be incurred through approximately December 31, 2027.

The consolidated financial statements also do not reflect any adjustments relating to the recoverability of assets and liabilities that might be necessary if the Company is unable to continue as a going concern. The Company has no recurring source of revenues and has experienced negative operating cash flows since inception.

The Company’s ability to continue as a going concern is dependent upon its ability to raise additional equity capital to fund its research and development activities and to ultimately achieve sustainable operating revenues and profitability.

As existing cash resources will not be sufficient to complete the clinical development of, and obtain regulatory approval for, the Company’s product candidate, the Company will need to raise additional capital in one or more tranches to fund its operations in the near-term in order to be able to effectively manage its current business plan during the remainder of 2024, the full year 2025, and thereafter. In addition, the Company’s operating plans and capital requirements may change as a result of many factors that are currently unknown and/or outside of the control of the Company. The Company is considering various strategies and alternatives to obtain the required additional capital. As market conditions present uncertainty as to the Company’s ability to secure additional funds, there can be no assurance that the Company will be able to secure additional financing on acceptable terms, as and when necessary, to continue to conduct operations. If cash resources are insufficient to satisfy the Company’s ongoing cash requirements, the Company would be required to scale back or discontinue its clinical trial program, or obtain funds, if available, through strategic alliances or joint ventures that could require the Company to relinquish rights to and/or control of LB-100, or to discontinue operations entirely.
