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 was able to increase the reach of its solutions in 2024, generating revenue from provider organizations and has continued the development of a more robust sales and partnership pipeline. To further increase reach and potentially accelerate partnerships and sales cycles, more seasoned sales personnel in the provider and employer verticals were hired in late 2024. In Q1 and Q2 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 the Medicare reimbursement process where the Company received preliminary gapfill pricing from the Centers for Medicare and Medicaid for the Epi+Gen CHD and PrecisionCHD tests, onboarding a new employer client and in setting up our laboratory facility.

On May 6, 2024, FDA published a final rule amending the definition of an in vitro diagnostic (“IVD”) device to include tests manufactured by a clinical laboratory. Pursuant to the rule, laboratory developed tests (“LDTs”), i.e., tests designed, manufactured, and used within a single CLIA-certified high complexity laboratory, are medical devices subject to FDA regulation under the Federal Food, Drug, and Cosmetic Act. The final rule also announced FDA’s intention to apply its medical device requirements to LDTs. Under the final rule, all LDTs, unless subject to a specific exemption, will be subject to premarket authorization requirements (510(k), de novo classification, or PMA) for each LDT performed by the laboratory, and to postmarket registration and listing, medical device reporting, correction, removal, and recall, complaint handling, labeling, investigational device, and quality system requirements. FDA intends to phase in these requirements beginning May 6, 2025. The final rule states that certain categories of LDTs will be subject to enforcement discretion with respect to some or all of these requirements. For example, FDA will apply enforcement discretion to currently marketed LDTs that were first offered prior to May 6, 2024, with respect to most quality system requirements and the requirement for premarket authorization if they are not modified or modified in only limited ways. Laboratories performing these tests are subject to other requirements, including the requirement to submit the labeling for the LDT to FDA for review. FDA will similarly exercise enforcement discretion with respect to premarket authorization for LDTs approved by the New York State Clinical Laboratory Evaluation Program (“NYS-CLEP”).

On February 2, 2024, we closed a private placement with seven accredited investors, whereby we issued a total of 18,727 (561,793 prior to the Reverse Stock Split) units (“Units”), with each Unit consisting of (i) one share of our Common Stock and (ii) one six-year Common Stock purchase warrant having an exercise price of $53.40 ($1.78 prior to the Reverse Stock Split) per share, subject to adjustment (the "Private Placement”). The Private Placement resulted in the issuance to investors of 18,727 (561,793 prior to the Reverse Stock Split) shares of Common Stock and 18,727 (561,793 prior to the Reverse Stock Split) warrants in an unregistered offering of securities. The purchase price of the securities was $53.40 ($1.78 prior to the Reverse Stock Split) Unit, resulting in gross proceeds to the Company of $1,000,000, before deducting placement agent fees (10% or $100,000) and other offering expenses. We used the net proceeds from the Private Placement for working capital and general corporate purposes.

Current wording

On February 2, 2024 (pre-dating the 1-for-30 reverse stock split effected in May 2025), in accordance with executed subscription agreements with seven accredited investors (the “Subscription Agreements”), we closed on the sale of 561,793 units (the “Units”), with each Unit consisting of (i) one share of the Company’s common stock, $0.00001 par value (the “Common Stock”) and (ii) one six year Common Stock purchase warrant (the “Warrants”), which warrants are exercisable until February 2, 2030 at an exercise price of $1.78 ($53.40 on a post-reverse stock split basis) per share, subject to adjustment for stock splits, reverse stock splits and other similar events of recapitalization, including the 1-for-30 reverse stock split we effected on May 12, 2025. The Units were sold to the investors in a private placement at a sale price of $1.78 ($53.40 on a post-reverse stock split basis) per Unit (the “Private Placement”), resulting in gross proceeds to the Company of $1,000,000, before deducting placement agent fees (10% or $100,000) and other offering expenses. We used the net proceeds from the Private Placement for working capital and general corporate purposes. On a post-reverse stock split basis, the Company issued 18,727 shares and warrants that are exercisable for 18,727 shares, all at an exercise price of $53.40 per share. We have subsequently registered the Private Placement Common Stock and the Common Stock issuable upon the exercise of the Private Placement Warrants on a registration statement on Form S-1 that was declared effective by the SEC on December 3, 2024 and subsequently on September 19, 2025.

At the upcoming 2025 annual meeting of stockholders, our stockholders will be asked to approve the future issuance of shares of Common Stock and/or securities convertible into or exercisable for Common Stock equal to 20% or more of the Common Stock outstanding in one or more non-public transactions as required by Nasdaq Marketplace Listing Rule 5635(d) (the "Share Issuance Proposal”). This proposal is identical to the proposals approved by our stockholders in 2023 and 2024, neither of which we relied upon for financing options, and the authorizations provided thereby expired. Any non-public financing transaction undertaken in connection with this approval will be conducted within the parameters set forth in the Share Issuance Proposal described in the proxy statement for the 2025 annual meeting, if the proposal is approved. We currently have no specific plans for such an offering but believe having that option available provides our Board of Directors with added flexibility in meeting the Company’s liquidity needs.

At our 2025 annual meeting of stockholders, our stockholders approved the future issuance of shares of Common Stock and/or securities convertible into or exercisable for Common Stock equal to 20% or more of the Common Stock outstanding in one or more non-public transactions as required by Nasdaq Marketplace Listing Rule 5635(d) (the "Share Issuance Proposal”). This proposal was identical to the proposals approved by our stockholders in 2023 and 2024, neither of which we relied upon for financing options, and the authorizations provided thereby expired. Any non-public financing transaction undertaken in connection with this approval will be conducted within the parameters set forth in the Share Issuance Proposal described in the proxy statement for the 2025 annual meeting. We currently have no specific plans for such an offering but believe having that option available provides our Board of Directors with added flexibility in meeting the Company’s liquidity needs.

Previous wording

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 $3.82 on August 13, 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.

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 six months ended June 30, 2025.
