Summary of Significant Accounting Policies and Recent Accounting Standards	2. Summary of Significant Accounting Policies and Recent Accounting Standards *Basis of Presentation* The condensed consolidated financial statements of the Company included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been condensed or omitted from this report, as is permitted by such rules and regulations. Accordingly, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025, filed with the SEC on February 26, 2026 (the “Annual Report”). The financial information as of March 31, 2026, and for the three months ended March 31, 2026 and 2025, is unaudited. In the opinion of management, all adjustments (including those which are normal and recurring) considered necessary for a fair presentation of the interim financial information have been included. The balance sheet data as of December 31, 2025, was derived from audited consolidated financial statements. The results of the Company’s operations for any interim periods are not necessarily indicative of the results that may be expected for any other interim period or for a full fiscal year. *Liquidity and going concern* The accompanying unaudited financial statements have been prepared assuming that the Company will continue as a going concern within one year after the date that the financial statements are issued. The Company’s future operations are highly dependent on the success of the Merger and there can be no assurances that the Merger will be successfully consummated. If the Merger is not consummated, the Company may seek other strategic alternatives or pursue a dissolution and liquidation. The Company anticipates that its cash position is sufficient to fund its operations at least through the anticipated closing of the proposed Merger with Eos. However, the Company expects to incur significant costs in connection with the Merger and even if the Merger is ultimately not consummated, including legal and professional services costs related to filing registration statements with the SEC and obtaining shareholder approval. As of March 31, 2026, the Company had $3.3 million in cash and cash equivalents, as well as $0.7 million in restricted cash that would become unrestricted following consummation of the Merger or upon any termination of the Merger Agreement in accordance with its terms. Management believes that, given the Company’s current cash position and forecasted negative cash flows from operating activities over the next twelve months, there is substantial doubt about its ability to continue as a going concern after the date that is one year from the date that these financial statements are issued without the closing of the Merger. The accompanying financial statements do not include any adjustments that might be necessary if the Company is not able to continue as a going concern. In order to continue development of its programs, the Company would need to secure substantial additional funding in the future, from one or more equity or debt financings, collaborations, or other sources. Additional funding may not be available to the Company on acceptable terms, or at all. Should the Company continue development of its product candidates, the Company would be subject to risks and uncertainties. The ongoing research and development activities will be subject to extensive regulation by numerous governmental authorities in the United States. Prior to marketing in the United States, any drug developed by the Company must undergo rigorous preclinical and clinical testing and an extensive regulatory approval process implemented by the United States Food and Drug Administration (“FDA”) under the Food, Drug and Cosmetic Act. The Company has limited experience in conducting and managing the preclinical and clinical testing necessary to obtain regulatory approval. There can be no assurance that the Company will not encounter problems in the clinical trials that will cause the Company or the FDA to delay or suspend clinical trials. The Company’s success in developing its product candidates would depend in part on its ability to obtain patents and product license rights, maintain trade secrets, and operate without infringing on the property rights of others, both in the United States and other countries.

The guidance in ASU 2026-01 clarifies how issuers initially measure paid-in-kind (“PIK”) dividends on equity-classified preferred stock by requiring issuers to use the PIK dividend rate stated in the preferred stock agreement. ASU 2026-01 will be effective for the Company’s annual reporting periods beginning after December 15, 2026, and for interim reporting periods within those annual periods, with early adoption permitted. Entities may apply the amendments on either a prospective basis or a modified retrospective basis for equity-classified preferred stock instruments that are outstanding as of the initial application date. The Company is currently evaluating the impact that adoption of ASU 2026-01 may have on its consolidated financial statements.

The financial information as of March 31, 2026, and for the three months ended March 31, 2026 and 2025, is unaudited. In the opinion of management, all adjustments (including those which are normal and recurring) considered necessary for a fair presentation of the interim financial information have been included. The balance sheet data as of December 31, 2025, was derived from audited consolidated financial statements. The results of the Company’s operations for any interim periods are not necessarily indicative of the results that may be expected for any other interim period or for a full fiscal year.

Liquidity and going concern

The accompanying unaudited financial statements have been prepared assuming that the Company will continue as a going concern within one year after the date that the financial statements are issued. The Company’s future operations are highly dependent on the success of the Merger and there can be no assurances that the Merger will be successfully consummated. If the Merger is not consummated, the Company may seek other strategic alternatives or pursue a dissolution and liquidation.

The Company anticipates that its cash position is sufficient to fund its operations at least through the anticipated closing of the proposed Merger with Eos. However, the Company expects to incur significant costs in connection with the Merger and even if the Merger is ultimately not consummated, including legal and professional services costs related to filing registration statements with the SEC and obtaining shareholder approval.

As of March 31, 2026, the Company had $3.3 million in cash and cash equivalents, as well as $0.7 million in restricted cash that would become unrestricted following consummation of the Merger or upon any termination of the Merger Agreement in accordance with its terms. Management believes that, given the Company’s current cash position and forecasted negative cash flows from operating activities over the next twelve months, there is substantial doubt about its ability to continue as a going concern after the date that is one year from the date that these financial statements are issued without the closing of the Merger.

The accompanying financial statements do not include any adjustments that might be necessary if the Company is not able to continue as a going concern.

In order to continue development of its programs, the Company would need to secure substantial additional funding in the future, from one or more equity or debt financings, collaborations, or other sources. Additional funding may not be available to the Company on acceptable terms, or at all.

Use of Estimates

In preparing the condensed consolidated financial statements in conformity with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, as well as the reported amounts of expenses during the reporting period. Due to inherent uncertainty involved in making estimates, actual results may differ from these estimates. On an ongoing basis, the Company evaluates its estimates and assumptions, with any changes applied prospectively.

Concentrations of Credit Risk

Cash and cash equivalents is a financial instrument that potentially subjects the Company to concentrations of credit risk. For all periods presented, substantially all of the Company’s cash was deposited in accounts at a single financial institution that management believes is creditworthy, and the Company has not incurred any losses to date. The Company is exposed to credit risk in the event of default by this financial institution for amounts in excess of the Federal Deposit Insurance Corporation insured limits.
