Risk factors and legal proceedings

The risks Vicor Corporation names in Item 1A of its 10-K filed Mar 2, 2026: 18 risks under these headings, as written.19

  • Operational Risks
  • Our future operating results are difficult to predict and are subject to fluctuations.
  • Global economic and political uncertainties, notably those associated with trade policy, could materially and adversely affect our business and consolidated operating results.
  • Our operating results recently have been influenced by a limited number of customers, and our future results may be similarly influenced.
  • We may not be able to procure necessary key components or raw materials, or we may purchase excess raw material inventory or unusable inventory, which increases the risk of reserve charges to reduce the value of any inventory deemed excess or obsolete, thereby reducing our profitability.
  • We rely on third-party vendors and subcontractors for supply of components, assemblies, and services and, therefore, cannot control the availability or quality of such components, assemblies, and services.
  • Extended interruption of production at our manufacturing facility in Andover, Massachusetts, or a failure to achieve anticipated efficiencies could materially reduce our revenue, increase our costs, and, potentially, negatively impact our customers.
  • Disruption of our information technology infrastructure could adversely affect our business.
  • Integrating artificial intelligence ("AI") and machine learning presents significant strategic advantages, yet necessitates a proactive approach to mitigating multifaceted business, financial, and legal risks.
  • We may face legal claims and litigation from product warranty or other claims that could be costly to resolve and could impact our business.
  • Our ability to successfully implement our business strategy may be limited if we do not retain our key personnel and attract and retain skilled and experienced personnel.
  • Our operations could be affected by the complex laws, rules and regulations to which our business is subject, and political and other actions may adversely impact our business.
The other 7 risks
  • Competitive Risks
  • We compete with many companies possessing far greater resources.
  • Our future success depends upon our ability to develop and market differentiated, leading-edge power conversion products for larger customers, potentially contributing to lengthy product development and sales cycles that may result in significant expenditures before revenues are generated. Our future operating results are dependent on the growth in such customers’ businesses and on our ability to profitably develop and deliver products meeting customer requirements.
  • Intellectual Property Risks
  • We may be unable to adequately protect our proprietary rights, which may limit our ability to compete effectively.
  • We face intellectual property infringement claims that could be disruptive to operations and costly to resolve and may encounter similar infringement claims in the future.
  • Any expenses or liability resulting from the outcome of litigation could adversely influence our operating results and financial condition.
  • Regulatory Risks
  • If we fail to maintain an effective system of internal controls over financial reporting or discover material weaknesses in our internal controls over financial reporting, we may not be able to report our financial results accurately or timely or detect fraud, which could have a material adverse effect on our business.
  • Risks Related to Share Value
  • The price of our Common Stock has been volatile and may fluctuate in the future.
