Risk factors and legal proceedings

The risks INTRUSION INC names in Item 1A of its 10-K filed Mar 25, 2026: 27 risks under these headings, as written.3

  • Risks Related to our Financial Position and Liquidity
  • The Company’s ability to implement its current business plan is dependent on our ability to raise additional funds through additional public or private financings, which raises substantial doubt that the Company may not be able to continue as a going concern.
  • We are subject to certain regulatory limitations that may affect our ability to consummate future financings.
  • We must increase revenue levels in order to finance our current operations and to implement our business strategies.
  • Business and Operational Risks
  • Most of our current revenues are generated from one family of solutions with a limited number of customers, and the decrease of revenue from sales of this family of solutions could materially harm our business and prospects.
  • We may not be successful in our efforts to broaden the marketing and sale of the INTRUSION Shield.
  • The current geo-political climate may add uncertainty in the dealings of our customers and could cause them to delay indefinitely certain cybersecurity initiatives or to determine not to introduce or implement any new or innovative cyber-solution products into their information networks.
  • A large percentage of our current revenues are received from U.S. government entities, and the loss of these customers or our failure to widen the scope of our customer base to include general commercial enterprises could negatively affect our revenues.
  • A decline in federal, state, or local government spending would likely negatively affect our product revenues and earnings.
  • We are highly dependent on sales of our current solutions through indirect channels, the loss of which would materially adversely affect our operations.
  • Our business depends on the continued service of our key management and technical personnel.
The other 17 risks
  • We could experience damage to our reputation in the cybersecurity industry in the event that our INTRUSION Shield solution fails to meet our customers’ needs or to achieve market acceptance.
  • If we fail to respond to rapid technological changes in the network security industry, we may lose customers, or our solutions may become obsolete.
  • We must expend time and resources addressing potential cybersecurity risks, and any breach of our information security safeguards could have a material adverse effect on the Company.
  • A breach of network security could harm public perception of our cybersecurity solutions, which could cause us to lose revenues.
  • If our solutions do not interoperate with our customers’ networks, installations will be delayed or cancelled and could harm our business.
  • We face intense competition from both start-up and established companies that may have significant advantages over us and our solutions.
  • If we are unable to implement and maintain effective internal control over financial reporting in the future, investors may lose confidence in the accuracy and completeness of our financial reports, and the market price of our common stock may decline.
  • Scarcity of products and materials in the supply chain could hinder or prevent the deployment of our INTRUSION Shield for our customers who elect to use the wired version of our solution.
  • We incur significantly increased costs because of operating as a public company, and our management is required to devote substantial time to compliance matters and initiatives.
  • Investment Risks
  • We experience volatility in the market for our common stock, particularly with respect to swings in the market price as well as volatility in the trading of our common stock.
  • Shares eligible for future sale may adversely affect the market.
  • You may experience dilution as a result of future equity offerings.
  • We have never paid dividends on our common stock and have no plans to do so in the future.
  • We are a “smaller reporting company,” and reduced disclosure requirements may make our common stock less attractive.
  • Risks Related to our Intellectual Property
  • We must adequately protect our intellectual property to prevent loss of valuable proprietary information.
  • We may incur substantial expenses defending ourselves against claims of infringement.
  • Our solutions are highly technical and if they contain undetected errors, our business could be adversely affected, and we might have to defend lawsuits or pay damages in connection with any alleged or actual failure of our solutions and services.

Legal proceedings

We may be subject to various claims that arise in the ordinary course of business. We do not believe that any claims exist where the outcome of such matters would have a material adverse effect on our consolidated financial position, operating results, or cash flows. However, there can be no assurance such legal proceedings will not have a material impact on our future results.
