Risk factors and legal proceedings

The risks Lumexa Imaging Holdings, Inc. names in Item 1A of its 10-K filed Mar 30, 2026: 50 risks under these headings, as written.6

  • Risks Related to Our Business and Our Industry
  • Our ability to generate revenue depends in large part on referrals from physicians and other healthcare providers.
  • Because many of our costs are fixed, lower scan volumes or other decreases to revenues could adversely affect the profitability of our business.
  • Our ability to maintain and attract new business depends upon the quality of our services, our reputation and the reputations of our radiologists, joint venture partners and the third-party providers with whom we contract.
  • If our contracted radiology practices terminate their agreements with us, our business could be negatively impacted.
  • We are dependent on our and our contracted radiology practices’ ability to hire and retain qualified radiologists and radiologic technologists, as well as our ability to hire and retain key personnel.
  • Our labor costs have been, and we expect they will continue to be, adversely affected by competition for staffing, the nationwide shortage of radiologists and experienced and skilled healthcare professionals and regulatory activity, including changes in minimum wage laws.
  • Our joint ventures depend on existing relationships with key health system partners. If we are unable to maintain synergistic relationships with these health systems, or enter into new relationships with health systems, we may be unable to implement our business strategies successfully.
  • Adverse changes in general domestic and worldwide economic conditions could adversely affect our business, financial condition, results of operations, liquidity and stock price.
  • We experience competition from other diagnostic imaging companies, hospitals and physician’s practices, and this competition could adversely affect our revenue and business.
  • If reimbursement rates paid by third-party governmental or commercial payors are reduced or if we fail to successfully manage the reimbursement and collections processes, our business, financial condition, results of operations, liquidity and stock price could be harmed.
  • There are risks associated with our current and potential future use of AI.
The other 39 risks
  • Hospitals may terminate their agreements with us, modify the types or reduce the volume of services requested or reduce fees paid to us.
  • We may be unable to effectively maintain our equipment or generate revenue when our equipment is not operational or being upgraded.
  • A disruption to the availability of medical equipment could cause a loss of revenue, which could adversely affect our business, financial condition, results of operations, liquidity and stock price.
  • Technological change in our industry could reduce the demand for our services and require us to incur significant costs to upgrade our equipment.
  • We may become subject to professional malpractice liability and other litigation claims, which could be costly and negatively impact our reputation and business.
  • If we are unable to obtain insurance, or if insurance becomes more costly for us to obtain, our business may be adversely affected.
  • Business interruptions due to natural disasters, including floods, fires, hurricanes and severe winter storms or other external events beyond our control, can adversely affect our business, financial condition, results of operations, liquidity and stock price.
  • Consolidation in the healthcare industry could adversely affect our business, financial condition, results of operations, liquidity and stock price.
  • We may not be able to successfully complete acquisitions or enter into new joint ventures on acceptable terms, which may slow our growth rate.
  • We may face risks with respect to our expansion strategy of opening de novo centers.
  • A restriction in our ability to make capital expenditures would restrict our growth and could adversely affect our business.
  • We may fail to realize all of the anticipated benefits of our past and any future acquisitions, or those benefits may take longer to realize than expected. We may also encounter significant difficulties in integrating these acquired businesses into our operations.
  • Our debt obligations could expose us to risks that could materially adversely affect our liquidity and financial condition.
  • We may be required to recognize an impairment of our goodwill, other intangible assets, or other long-lived assets, which could have an adverse effect on our business, financial condition, and results of operations, liquidity and stock price.
  • Our business exhibits seasonal fluctuations that could cause significant fluctuation in our quarterly operating results, which could increase the volatility of our stock price and cause losses to our stockholders.
  • Data Protection and Cybersecurity Related Risks
  • Cybersecurity threats and other disruption or malfunctions in our information technology systems could adversely affect our business.
  • Actual or perceived failures to comply with applicable data protection, privacy and security laws, regulations, standards and other requirements could adversely affect our business, financial condition, results of operations, liquidity and stock price.
  • Healthcare and Regulatory Related Risks
  • The regulatory framework in which we operate is uncertain and continually evolving and complying with federal and state regulations is an expensive and time-consuming process.
  • If we fail to comply with various licensure, certification and accreditation standards, we may be subject to loss of licensure, certification or accreditation, which would adversely affect our operations.
  • Our operations and relationships with radiologists must be structured to avoid the corporate practice of medicine and fee-splitting and ensure compliance with other federal and state laws. Any violation of these laws would subject us to potential damages, injunction or civil and criminal penalties and could require us to restructure our operations or relationships with radiologists in a way that would affect the control or quality of our services.
  • State efforts to regulate the construction or expansion of healthcare facilities could impair our ability to operate and expand our operations.
  • Some of our imaging modalities use radioactive materials, which generate regulated waste and could subject us to liabilities for injuries or violations of environmental and health and safety laws.
  • Government authorities or other parties may assert that our business practices violate antitrust laws.
  • Risks Relating to the Ownership Our Common Stock
  • An active trading market for our common stock may not be sustained, and you may not be able to resell your shares of our common stock at or above the initial offering price you paid.
  • Our operating results and share price may be volatile.
  • If our operating and financial performance in any given period does not meet the guidance that we provide to the public, the price of our common stock may decline.
  • Future sales, or the perception of future sales, of our common stock may depress the price of our common stock. In addition, a significant portion of our common stock is restricted from immediate resale but may be sold into the market in the near future. This could cause the market price of our common stock to drop significantly, even if our business is doing well.
  • If securities or industry analysts do not publish research or publish misleading or unfavorable research about our business, our share price and trading volume may decline.
  • We do not intend to pay cash dividends for the foreseeable future, and accordingly, stockholders must rely on stock appreciation for any return on their investment.
  • We will continue to incur significant costs as a result of operating as a public company.
  • The accuracy of our financial statements and related disclosures could be affected if the judgments, assumptions or estimates used in our critical accounting policies are inaccurate.
  • We have identified material weaknesses in our internal control over financial reporting. If we are unable to remediate these material weaknesses, or if we identify additional material weaknesses in the future or otherwise continue to fail to maintain effective internal control over financial reporting, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect our business and share price.
  • Our failure to maintain effective internal controls over financial reporting could have an adverse impact on us.
  • We are an “emerging growth company” and our election of reduced reporting requirements applicable to emerging growth companies may make our common stock less attractive to investors.
  • WCAS and management own a significant percentage of our common stock and will be able to exert significant control over matters subject to stockholder approval and their interests may conflict with your interests as an owner of our common stock.
  • Certain of our directors may have conflicts of interest because of their ownership of equity interests of, and their employment with, WCAS and its affiliates.
  • Our amended and restated certificate of incorporation contains exclusive forum provisions that may limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, stockholders, officers or other employees.
  • Our amended and restated certificate of incorporation contains a provision renouncing our interest and expectancy in certain corporate opportunities.
  • Some provisions of Delaware law and our governing documents could discourage a takeover that stockholders may consider favorable.

Legal proceedings

We are subject to litigation arising in the ordinary course of our business, including litigation principally relating to professional liability. There can be no assurance that our insurance coverage and self-insured liabilities will be adequate to cover all liabilities occurring out of such claims. From time to time, we receive requests for information from government agencies in connection with their regulatory or investigational authority. Such requests can include subpoenas or demand letters for documents to assist the government in audits or investigations. We review such requests and notices and take appropriate action. We have been subject to certain requests for information and investigations and could be subject to such requests for information and investigations in the future. In the opinion of management, we are not engaged in any legal proceedings that we expect will have a material adverse effect on our business, financial condition, cash flows or results of our operations.
