Description of Business, Basis of Presentation and Going Concern	Description of Business, Basis of Presentation and Going Concern Description of Business Exicure, Inc. has historically been an early-stage biotechnology company focused on developing nucleic acid therapies targeting ribonucleic acid against validated targets. In September 2022, the Company announced a significant reduction in force, suspension of preclinical activities and halting of all research and development, and that the Company was exploring strategic alternatives to maximize stockholder value. While the foregoing efforts are continuing, with respect to the Company’s historical assets, the Company does not expect they will generate significant value for stockholders. Therefore, the Company is engaging in a broader exploration of strategic alternatives. This effort involves exploring growth through transactions with potential partners that see opportunity in joining an existing, publicly-traded organization. The Company is exploring transactions in industries unrelated to its historical operations. Throughout these consolidated financial statements, the terms the “Company,” and “Exicure” refer to Exicure, Inc. and where appropriate, its wholly owned subsidiary, Exicure Operating Company. Exicure Operating Company holds all material assets and conducts all business activities and operations of Exicure, Inc. Basis of Presentation These consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission and accounting principles generally accepted in the United States of America (“US GAAP”) as defined by the Financial Accounting Standards Board (“FASB”) within the FASB Accounting Standards Codification (“ASC”) and are presented in thousands, except number of shares and per share data. Principles of Consolidation The accompanying consolidated financial statements include the accounts of Exicure, Inc. and its wholly owned subsidiary, Exicure Operating Company. All intercompany transactions and accounts are eliminated in consolidation. Reclassification Certain accounts in the prior period consolidated financial statements have been reclassified to conform to the presentation of the current year consolidated financial statements. These reclassifications had no effect on the previously reported operating results. Going Concern At each reporting period, the Company evaluates whether there are conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern for a period of one year after the date that the financial statements are issued. The Company is required to make certain additional disclosures if it concludes substantial doubt exists and it is not alleviated by the Company’s plans or when its plans alleviate substantial doubt about the Company’s ability to continue as a going concern. The accompanying financial statements have been prepared assuming that the Company will continue as a going concern for a period of one year after the date that the financial statements are issued. As of December 31, 2023, the Company expects to incur significant expenses and negative cash flows for the foreseeable future. As of December 31, 2023, the Company’s cash and cash equivalents were $816. Management believes that given the Company’s current cash position, operating plans and forecasted negative cash flows from operating activities over the next twelve months, there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date these financial statements are issued. The Company has no committed sources of additional capital at this time and substantial additional financing will be needed by the Company to fund its operations. Management believes that the Company’s existing cash and cash equivalents are insufficient to continue to fund its operating expenses and additional funding is needed in the very near term. The Company has already engaged in significant cost reductions, so our ability to further cut costs and extend the Company’s operating runway is limited. As a result, substantial additional financing will be needed by the Company in the very near term to pay expenses, fund the ongoing exploration of strategic alternatives and pursue any alternatives that may be identified. There can be no assurance that such additional financing will be available and, if available, can be obtained on acceptable terms. The accompanying consolidated financial statements have been prepared as though the Company will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern. Use of Estimates The preparation of the financial statements in conformity with US GAAP requires management 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Management bases its estimates on certain assumptions which it believes are reasonable in the circumstances and while actual results could differ from those estimates, management does not believe that any change in those assumptions in the near term would have a significant effect on the Company’s financial position, results of operations or cash flows. Actual results in future periods could differ from those estimates.
