EXPLANATORY NOTE

Check-Cap Ltd. (“Check-Cap”, the “Company” or “we”) is a clinical stage medical diagnostics company with a limited operating history. On June 6, 2023, we announced that after further review of additional data and interaction with the Food and Drug Administration on a revised pivotal study protocol together with the anticipated time and investment necessary to further develop the technology, we were reducing our workforce significantly to reduce cash burn, concentrating our resources on essential research activities, discontinuing our calibration studies, and evaluating and pursuing strategic options. As a result of our evaluation and pursuit of strategic options, on August 16, 2023, we entered into a business combination agreement (the “Keystone BCA”) with Keystone Dental Holdings, Inc. (“Keystone”), Capstone Dental PubCo, Inc (“PubCo”) and other direct, wholly owned subsidiaries of PubCo. At our 2023 annual general meeting of shareholders, such business combination transactions did not receive the requisite majority required for approval under Section 320 of the Israeli Companies Law 5759-1999. On December 24, 2023, we received a notice on behalf of Keystone, terminating the Keystone BCA in light of the results. On March 25, 2024, we entered into a business combination agreement with Apollo Technology Capital Corporation (formerly known as Nobul AI Corp.) (“Nobul”), a private Ontario corporation (the “Business Combination”). If the Business Combination is consummated, Check-Cap’s ordinary shares will be delisted from Nasdaq and deregistered under the Securities Exchange Act of 1934, as amended, and Check-Cap will no longer be required to file periodic reports with the U.S. Securities and Exchange Commission. Given that this Annual Report on Form 20-F provides the financial statements for the fiscal years ended December 31, 2024, 2023, and 2022, we have elected to discuss the significant aspects of our historical business as well as the current state of our business.

FORWARD-LOOKING STATEMENTS

This Annual Report contains forward-looking statements about our expectations, beliefs or intentions regarding, among other things, our plans with respect to the our evaluation and pursuit of strategic options including the transactions contemplated by our Business Combination Agreement with Nobul, our ongoing and planned product development and clinical trials and lack thereof; the timing of, and our ability to make, regulatory filings and obtain and maintain regulatory approvals for our product candidates; our intellectual property position; the degree of clinical utility of our products, particularly in specific patient populations; our ability to develop commercial functions; expectations regarding product launch and revenue; our results of operations; cash needs; financial condition, liquidity, prospects, growth and strategies; the industry in which we operate; and the trends that may affect the industry or us. In addition, from time to time, we or our representatives have made or may make forward-looking statements, orally or in writing. Forward-looking statements can be identified by the use of forward-looking words such as “believe,” “expect,” “intend,” “plan,” “may,” “should” or “anticipate” or their negatives or other variations of these words or other comparable words or by the fact that these statements do not relate strictly to historical or current matters. These forward-looking statements may be included in, but are not limited to, various filings made by us with the U.S. Securities and Exchange Commission, or the SEC, press releases or oral statements made by or with the approval of one of our authorized executive officers. Forward-looking statements relate to anticipated or expected events, activities, trends or results as of the date they are made. Because forward-looking statements relate to matters that have not yet occurred, these statements are inherently subject to risks and uncertainties that could cause our actual results to differ materially from any future results expressed or implied by the forward-looking statements. Many factors could cause our actual activities or results to differ materially from the activities and results anticipated in forward-looking statements, including, but not limited to, the factors summarized below.

This Annual Report identifies important factors which could cause our actual results to differ materially from those indicated by the forward-looking statements, particularly those set forth under the heading “Risk Factors.” The risk factors included in this Annual Report are not necessarily all of the important factors that could cause actual results to differ materially from those expressed in any of our forward-looking statements. Given these uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements. Factors that could cause our actual results to differ materially from those expressed or implied in such forward-looking statements include, but are not limited to:

vi

All forward-looking statements attributable to us or persons acting on our behalf speak only as of the date of this Annual Report and are expressly qualified in their entirety by the cautionary statements included in this Annual Report. We undertake no obligations to update or revise forward-looking statements to reflect events or circumstances that arise after the date made or to reflect the occurrence of unanticipated events. In evaluating forward-looking statements, you should consider these risks and uncertainties.

MARKET AND INDUSTRY DATA

Market data and certain industry data and forecasts used throughout this Annual Report were obtained from internal company surveys, market research, consultant surveys commissioned by the Company, publicly available information, reports of governmental agencies and industry publications and surveys. Industry surveys, publications, consultant surveys commissioned by the Company and forecasts generally state that the information contained therein has been obtained from sources believed to be reliable. However, this information may prove to be inaccurate because of the method by which some of the data for the estimates is obtained or because this information cannot always be verified with complete certainty due to the limits on the availability and reliability of raw data, the voluntary nature of the data gathering process and other limitations and uncertainties. As a result, the market and industry data and forecasts included or incorporated by reference in this Annual Report, and estimates and beliefs based on that data, may not be reliable. We have relied on certain data from third-party sources, including internal surveys, industry forecasts and market research, which we believe to be reliable based on our management’s knowledge of the industry. However, we have not ascertained the underlying economic assumptions relied upon therein. Forecasts are particularly likely to be inaccurate, especially over long periods of time. In addition, we do not necessarily know what assumptions regarding general economic growth were used in preparing the forecasts we cite. Statements as to our market position are based to the best of our knowledge on the most currently available data. While we are not aware of any misstatements regarding the industry data presented in this Annual Report, our estimates involve risks and uncertainties and are subject to change based on various factors, including those discussed under the heading “Risk Factors” in this Annual Report.
