Management, including the CODM, reviews operating results solely by monthly revenue and operating results of the Company and, as such, the Company has determined that the Company has one operating segment (product testing) as defined by ASC Topic 280 “Segment Reporting”.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">One hundred percent of the Company’s revenues are generated from products testing for major types of cardiovascular disease, and therefore the Company has one operating segment for financial reporting purposes. The Company’s principal products are its Epi+Gen CHD and PrecisionCHD tests. Epi+Gen CHD assesses the risk for a coronary heart disease event, including a heart attack, in the next three years. PrecisionCHD aids in diagnosing and managing coronary heart disease. The tests can be paid for by provider organizations, patients, and/or employers. Customers are generally charged for tests utilized or for the minimum committed test volume and the pricing can vary based on organization type, size and volume.<b> </b></p> <p style="font: 10pt Times New Roman, Times, Serif;

margin: 0pt 0">At the commencement of efforts to pursue what ultimately ended in a terminated business acquisition, Legacy Cardio entered into a Placement Agent and Advisory Services Agreement (the “Placement Agent Agreement”), dated April 12, 2021, with Boustead Securities, LLC ("Boustead Securities”). This agreement was terminated in April 2022, when Legacy Cardio terminated the underlying agreement and plan of merger and the accompanying escrow agreement relating to that proposed business acquisition after efforts to complete the transaction failed, despite several extensions of the closing deadline.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Under the terminated Placement Agent Agreement, Legacy Cardio agreed to certain future rights in favor of Boustead Securities, including (i) a two-year tail period during which Boustead Securities would be entitled to compensation if Cardio were to close on a transaction (as defined in the Placement Agent Agreement) with any party that was introduced to Legacy Cardio by Boustead Securities; and (ii) a right of first refusal to act as the Company’s exclusive placement agent for 24-months from the end of the term of the Placement Agent Agreement (the “right of first refusal”). Cardio has taken the position that due to Boustead Securities’ failure to perform as contemplated by the Placement Agent Agreement, these provisions purporting to provide future rights are null and void.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0">Boustead Securities responded to the termination of the Placement Agent Agreement by disputing Legacy Cardio’s contention that it had not performed under the Placement Agent Agreement because, among other things, Boustead Securities had never sought out prospective investors. In its response, Boustead Securities included a list of funds that they had supposedly contacted on Legacy Cardio’s behalf. While Boustead Securities’ contention appears to contradict earlier communications from Boustead Securities in which they indicated that they had not made any such contacts or introductions, Boustead Securities contended that they are due success fees for two years following the termination of the Placement Agent Agreement on any transaction with any person on the list of supposed contacts or introductions. Legacy Cardio strongly disputes this position. Notwithstanding the foregoing, the Company has not consummated any transaction, as defined, with any potential party that purportedly was a contact of Boustead Securities in connection with the Placement Agent Agreement and has no plans to do so at any time during the tail period.

In addition, the Amendment Engagement provided that Benchmark has been granted a right of first refusal to act as lead or joint-lead investment banker, lead or joint-lead book- runner and/or lead or joint-lead placement agent for all future public and private equity and debt offerings through October 25, 2023.</span> Based on the right of first refusal, Benchmark alleges that it is owed damages because the Company entered into the Yorkville Convertible Debenture Transaction without first offering Benchmark the right to serve as the lead or joint-lead placement agent for the transaction.

Subsequent thereto, the Company filed amendments to the S-4 Registration Statement on July 27, 2022, August 23, 2022, September 15, 2022, October 4, 2022 and October 5, 2022 in which it responded to various comments of the SEC staff and otherwise updated its disclosure. In October 2022, the SEC completed its review and declared the S-4 registration statement effective on October 6, 2022. On February 23, 2023 and February 27, 2023, plaintiffs’ securities law firm contacted the Company’s counsel asking who will be negotiating a mootness fee relating to the purported claims set forth in the June 25, 2022 demand letter. The Company vigorously denies that the S-4 Registration Statement, as amended and declared effective, is deficient in any respect and that no additional supplemental disclosures are material or required. The Company believes that the claims asserted in the Demand Letter are without merit and that no further disclosure was required to supplement the S-4 Registration Statement under applicable laws. As of the date of filing of this Quarterly Report on Form 10-Q, no lawsuit has been filed against the Company by that firm. The firm has indicated its willingness to litigate the matter if a mutually satisfactory resolution cannot be agreed upon; however, Cardio believes that the final outcome will not have a material adverse impact on its financial condition.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><b><span style="text-decoration: underline">Northland Securities, Inc.</span></b></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In January 2024, following the Company’s termination of its agreement with Yorkville and in connection with the Company’s at the market offering and/or its February 2024 private placement, a managing director of Northland Securities, Inc.
