The risks most specific to Vicor
- Operational Risks
Our operating results recently have been influenced by a limited number of customers, and our future results may be similarly influenced
Advanced Products revenue has historically depended on one or a limited number of customers, including through contract manufacturers and royalties.
- Operational Risks
Global economic and political uncertainties, notably those associated with trade policy, could materially and adversely affect our business and consolidated operating results
International exposure and trade-policy changes threaten results; 48.2% of 2024 revenue was outside the United States and China/Hong Kong contributed 12.6%.
- Operational Risks
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
Demand swings could cause component shortages or excess and obsolete inventory, requiring reserve charges that reduce profitability.
- Operational Risks
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
Third-party vendors and subcontractors, including single-source suppliers, may provide components or services late, at higher cost, or with inadequate quality.
- Operational Risks
The majority of our power components and power systems, whether for direct sale to customers or for sale to our subsidiaries for incorporation into their respective products, are manufactured in our Andover facility
Most power components and systems are manufactured at the Andover facility, so damage or power loss could halt production and delay shipments.
- Operational Risks
Disruption of our information technology infrastructure could adversely affect our business
Failures or breaches affecting IT, email, the website, financial records, or Andover’s computer-integrated manufacturing systems could disrupt operations.
- Operational Risks
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
The company depends on key personnel, particularly founder, Chairman, CEO, and President Dr. Vinciarelli, whose departure could harm results.
- Operational Risks
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
Worldwide requirements covering intellectual property, tariffs, exports, taxes, anti-corruption, data privacy, employment, and products could restrict operations or increase costs.
- Operational Risks
We may be unable to adequately protect our proprietary rights, which may limit our ability to compete effectively
Failure to protect patents and proprietary technologies could let competitors use Vicor innovations and weaken its ability to compete.
- Operational Risks
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
Third parties may claim Vicor products or manufacturing processes infringe patents or other intellectual property, causing disruption and legal expense.

About this page
Item 1A of the 10-K on EDGAR was split into its risk factors and, where the company's previous 10-K is on file, each heading was matched to last year's and the text compared word for word. The headings are the filing's own. The one-line readings and the overview were written by a language model from the text of the new, dropped, and rewritten risks; they refer to risks by position and cannot misquote a heading.
