Risk factors and legal proceedings
The risks Cardio Diagnostics Holdings, Inc. names in Item 1A of its 10-K filed Mar 13, 2026: 67 risks under these headings, as written.4
- Risks Related to Our Limited Operating History and Early Stage of Growth
- We are a medical diagnostic testing company with a limited operating history and have not yet generated significant revenue from product sales. We have incurred operating losses since our inception and may never achieve or maintain profitability.
- The healthcare commercialization process is inherently lengthy and subject to regulatory, reimbursement, evidentiary and behavioral factors, which, combined with clinical adoption of novel diagnostic technologies that frequently spans multiple years, results in a lengthy period from initial development to widespread utilization and ultimately to revenue generation, which, in some cases, may span a decade or more.
- We believe our long-term value as a company will be greater if we focus on growth, which has in the past, and may continue to negatively impact our results of operations in the near term.
- Our business and the markets in which we operate are new and rapidly evolving, which make it difficult to evaluate our future prospects and the risks and challenges we may encounter.
- Our limited operating history makes it difficult to evaluate our future prospects and the risks and challenges we may encounter.
- Our quarterly results may fluctuate significantly and may not fully reflect the underlying performance of our business.
- We expect to need to raise additional capital to fund our existing operations or develop and commercialize new services or expand our operations.
- We may invest in or acquire other businesses, and our business may suffer if we are unable to successfully integrate an acquired business into our company or otherwise manage the growth associated with multiple acquisitions.
- We may experience difficulties in managing our growth and expanding our operations.

- We have an unproven business model with no assurance of significant revenues or operating profit.
The other 57 risks
- The market for epigenetic tests is fairly new and unproven, and it may decline or experience limited growth, which would adversely affect our ability to fully realize the potential of our platform.
- The estimates of market opportunity and forecasts of market growth included in this Annual Report on Form 10-K may prove to be inaccurate, and even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates, if at all.
- If we are not able to enhance or introduce new products that achieve market acceptance and keep pace with technological developments, our business, results of operations and financial condition could be harmed.
- The success of our business depends on our ability to expand into new vertical markets and attract new customers in a cost-effective manner.
- Consolidation in the health care industry could have a material adverse effect on our business, financial condition and results of operations.
- If we are not able to compete effectively, our business and operating results will be harmed.
- Our business depends on customers increasing their use of our solutions, and we may experience loss of customers or decline in their use of our solutions.
- Our technologies and products leverage and incorporate AI and machine learning, and their development, maintenance, and operational success are subject to various risks and uncertainties, some of which are beyond our control and may adversely affect our business, results of operations and financial condition, and may also result in reputational harm and liability.

- The information that we provide to our customers could be inaccurate or incomplete, which could harm our business reputation, financial condition, and results of operations.
- Our proprietary applications may not operate properly, which could damage our reputation, give rise to a variety of claims against us, or divert our resources from other purposes, any of which could harm our business and operating results.
- If we do not keep pace with technological changes, our solutions may become less competitive, and our business may suffer.
- Our growth strategy may not prove viable and expected growth and value may not be realized.
- Market and economic conditions may negatively impact our business, financial condition and stock price.

- Our future growth could be harmed if we lose the services of our key personnel.
- If we are unable to hire, retain and motivate qualified personnel, our business will suffer.
- If we cannot maintain our corporate culture as it grows, we could lose the innovation, teamwork, passion and focus on execution that it believes contribute to its success, and its business may be harmed.

- Our Board of Directors may change its strategies, policies, and procedures without stockholder approval, and we may become highly leveraged, which may increase our risk of default under our existing or future obligations.
- We may need to seek alternative business opportunities and change the nature of our business.
- Any legal proceedings or claims against us could be costly and time-consuming to defend and could harm our reputation regardless of the outcome.
- Risks Related to our Intellectual Property
- Our license agreement with the University of Iowa Research Foundation includes a non-exclusive license of “technical information” that potentially could grant unaffiliated third parties access to materials and information considered derivative work made by us, which could be used by such licensees to develop competitive products.
- We could incur substantial costs in protecting or defending our intellectual property rights, and any failure to protect or defend our intellectual property could adversely affect our business, results of operations and financial condition.
- Assertions by third parties of infringement or other violations by us of its intellectual property rights could result in significant costs and harm our business and operating results.
- Certain of our core technology is licensed, and that license may be terminated if we were to breach our obligations under the license.
- Some of our technologies incorporate “open-source” software or other similar licensed technologies, which could become unavailable or subject us to increased costs, delays in production or assessment or litigation.
- Intellectual property that is in-licensed may have been made using government funding and, thus, may be subject to federal regulations under the Bayh-Dole Act.
- Risks Related to Government Regulation
- We conduct business in a heavily regulated industry, and if we fail to comply with these laws and government regulations, we could incur penalties or be required to make significant changes to our operations or experience adverse publicity, which could have a material adverse effect on our business, financial condition, and results of operations.
- If the FDA were to begin actively regulating our tests or software, we could incur substantial costs and delays associated with trying to obtain premarket 510(k) clearance, de novo classification, or premarket approval and incur costs associated with complying with post-market controls.
- If our products do not receive adequate coverage and reimbursement from third-party payors, our ability to expand access to our tests beyond the initial sales channels will be limited and our overall commercial success will be limited.
- Our products may fail to achieve the degree of market acceptance necessary for commercial success.
- Risks Related to Customer Privacy, Cybersecurity and Data
- Our use and disclosure of personally identifiable information, including health information, is subject to federal and state privacy and security regulations, and our failure to comply with those regulations or to adequately secure the information we hold could result in significant liability or reputational harm and, in turn, a material adverse effect on our customer base and revenue.
- Privacy and data security laws and regulations could require us to make changes to our business, impose additional costs on us and reduce the demand for our tests and services.
- General Risks Affecting Our Company
- A pandemic, epidemic or outbreak of an infectious disease in the United States or worldwide, including the re-emergence of the novel strain of coronavirus disease, COVID-19, could adversely affect our business.
- Changes in accounting standards and subjective assumptions, estimates and judgments by management related to complex accounting matters could significantly affect our financial results or financial condition.
- Risks Related to Our Securities
- We are an “emerging growth company” and “smaller reporting company” within the meaning of the Securities Act, and if we take advantage of certain exemptions from disclosure requirements available to emerging growth companies, it could make our securities less attractive to investors and may make it more difficult to compare our performance to the performance of other public companies.
- Our stock price may be volatile and may decline regardless of our operating performance.
- An active trading market for our Common Stock may not be created or sustained.
- Future sales of Common Stock in the public market could cause our share price to decline significantly, even if our business is doing well.
- If securities or industry analysts either do not publish research about us or publish inaccurate or unfavorable research about us, our business, or our market, or if they change their recommendations regarding our Common Stock adversely, the trading price or trading volume of our Common Stock could decline.
- Delaware law and provisions in our Charter and Bylaws could make a merger, tender offer, or proxy contest difficult, thereby depressing the trading price of our Common Stock.
- Our Bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between the Company and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with the Company or our directors, officers or employees.
- We do not intend to pay dividends for the foreseeable future.
- We may issue additional shares of our Common Stock or other equity securities without your approval, which would dilute your ownership interests and may depress the market price of our Common Stock.
- We may redeem the Public Warrants and the Sponsor Warrants prior to their exercise at a time that is disadvantageous to you, as a warrant holder, thereby making your Public Warrants or Sponsor Warrants worthless.
- Exercise of our Warrants is dependent upon the trading price of our Common Stock. Because of the disparity between the current stock price and the respective Warrant exercise prices, the Warrants may never be in the money and may expire worthless.
- The Warrant Agreement designates the courts of the State of New York or the United States District Court for the Southern District of New York as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by holders of the Warrants, which could limit the ability of warrant holders to obtain a favorable judicial forum for disputes with our Company.
- Financial reporting obligations of being a public company in the United States are expensive and time-consuming, and our management will be required to devote substantial time to compliance matters.
- If we fail to comply with the rules under Sarbanes-Oxley related to accounting controls and procedures in the future, or, if we discover material weaknesses and other deficiencies in our internal control and accounting procedures, our stock price could decline significantly and raising capital could be more difficult.
- We will need to grow the size of our organization and may experience difficulties in managing this growth.
- There can be no assurance that we will be able to comply with the continued listing standards of Nasdaq, and delisting of our securities could become more likely if a proposed Nasdaq rule currently being considered is adopted, as expected .
