Previous wording

Cardio was formed to further develop and commercialize a series of products for major types of cardiovascular disease and associated co-morbidities, including coronary heart disease (“CHD”), stroke, heart failure and diabetes, by leveraging our Artificial Intelligence (“AI”)-driven Integrated Genetic-Epigenetic Engine™. As a company, we aspire to give every American adult insight into their unique risk for various cardiovascular diseases. Cardio aims to become one of the leading medical technology companies for enabling improved prevention, early detection and treatment of cardiovascular disease. Cardio is transforming the approach to cardiovascular disease from reactive to proactive and hope to accelerate the adoption of Precision Medicine for all. We believe that incorporating Cardio’s solutions into routine practice in primary care and prevention efforts can help alter the trajectory that nearly one in two Americans is expected to develop some form of cardiovascular disease by 2035.

Cardio launched its first clinical test, Epi+Gen CHD™, a three-year symptomatic CHD risk assessment clinical blood test targeting CHD events, including heart attacks, in 2021 during the Covid-19 pandemic. As a result, the initial strategy for commercialization involved launching the test via telemedicine and in smaller provider practices such as concierge medicine practices. The volume of tests through these channels were minimal, and as the circumstances around Covid-19 pandemic improved, management re-vamped the Company’s go-to-market strategy to include other healthcare verticals and stakeholders beyond patients and small providers, including larger provider organizations, group purchasing organizations, employers, payors and life insurers. This new approach allowed Cardio to expand the reach of our solutions beyond the initial focus areas. Beyond the launch of Epi+Gen CHD, in March 2023, we announced the launch of our second product, PrecisionCHD™, an integrated epigenetic-genetic clinical blood test for the detection of coronary heart disease. The Epi+Gen CHD™ and PrecisionCHD™ tests are coupled to Actionable Clinical Intelligence (“ACI”), a platform that offers new epigenetic and genetic insights to clinicians prescribing the to personalize patient management and help improve chronic care management. In May 2023, we launched CardioInnovate360™, a research-use-only (“RUO”) solution to support the discovery, development and validation of novel biopharmaceuticals for the assessment and management of cardiovascular diseases. In February 2024, we announced the launch of HeartRisk™, a cardiovascular disease risk intelligence platform. We believe that our Epi+Gen CHD™ and PrecisionCHD™ tests are categorized as laboratory-developed tests, or “LDTs.” The new go-to-market strategy is also being implemented for these products. Despite long partnership and sales cycles, in some instance as long as 14 months, Cardio has been able to increase the number of provider organizations offering its tests and has continued the development of a more robust sales and partnership pipeline. In the nine months ended September 30, 2025, the focus of the Company remained in driving adoption of our clinical solutions, predominantly among providers, channel partners and employers. In addition, the Company made progress in its ongoing expansion to additional markets such as the VA and international, partnering with the YMCA of East Tennessee to offer testing to its members and community, and in setting up our laboratory facility.

Finally, the setup of the Company’s new high complexity CLIA lab was completed with the initial CLIA survey conducted by a CLIA compliance manager and found no deficiencies. In addition to the federal certification requirements, the laboratory also received its out-of-state licenses from California, Maryland, Pennsylvania, and Rhode Island. Testing of patient samples have commenced at this facility for samples…

We have had, and expect that we will continue to have, an ongoing need to raise additional cash from outside sources to fund our operations and grow our business. We expect that our primary cash needs for the remainder of 2025 and for the foreseeable future will be for funding day-to-day operations and working capital requirements, funding our growth strategy, paying the setup expenses of our internal laboratory and paying expenses incurred in connection with our ongoing FDA submission activities. We explore our financing options on an ongoing basis. However, given recent stock prices and the extreme volatility of our stock, it continues to be challenging to balance cash that could be raised and the dilution that might be required to close a particular transaction. We expect that for the remainder of 2025, we will rely primarily on the ongoing ATM Offering, provided that market conditions are favorable.

In order to have sufficient cash to fund our operations beyond the next 12 months and grow our business, we will need to raise additional funds through the issuance of equity and/or debt. We cannot provide any assurance that we will be successful in doing so.

The exercise prices of our currently outstanding warrants range from a high of $345 to a low of $53.40 (a high of $11.50 to a low of $1.78 before the Reverse Stock Split) (subject to adjustment) per share of Common Stock. The likelihood that warrant holders will exercise their warrants, and therefore the amount of cash proceeds that we might receive, is dependent upon the trading price of our Common Stock, the last reported sales price for which was 3.86 on November 10, 2025. If the trading price of our Common Stock is less than the respective exercise prices of our outstanding warrants, which has been the case for a substantial period of time, we believe holders of any of our warrants will be unlikely to exercise their warrants. There is no guarantee that the warrants will be in the money prior to their respective expiration dates, and as such, the warrants may expire worthless, and we may receive no proceeds from the exercise of warrants. Given the current differential between the trading price of our Common Stock and the Warrant exercise prices and the volatility of our stock price, we are not making strategic business decisions based on an expectation that we will receive any cash from the exercise of warrants. However, we will use any cash proceeds received from the exercise of warrants for general corporate and working capital purposes, which would increase our liquidity. We will continue to evaluate the probability of warrant exercises and the merit of including potential cash proceeds from the exercise of the warrants in our future liquidity projections.

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 is currently contending 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. No legal proceedings have been instigated by either party, and Cardio believes that the final outcome will not have a material adverse impact on its financial condition.

On June 25, 2022, a plaintiffs’ securities law firm sent a demand letter to the Company alleging that the Company’s Registration Statement on Form S-4 filed (the “S-4 Registration Statement”) with the Securities and Exchange Commission (“SEC”) on May 31, 2022 omitted material information with respect to the Business Combination and demanding that the Company and its Board of Directors immediately provide corrective disclosures in an amendment or supplement to the Registration Statement. 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 believes 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.

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 believes 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.

Our senior management has reviewed the critical accounting policies and estimates with the Audit Committee of our Board of Directors. For a description of the Company’s critical accounting policies and estimates, refer to “Part II—Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates” in our most recent Annual Report on Form 10-K for the year ended December 31, 2024, which was filed with the SEC on March 20, 2025. Critical accounting policies are those that are most important to the portrayal of our financial condition, results of operations and cash flows and require management’s most difficult, subjective and complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. If actual results were to differ significantly from estimates made, the reported results could be materially affected. There were no significant changes to our critical accounting policies and estimates during the three and nine months ended September 30, 2025.
