Vicor Corp: what insiders have been doing
Vicor Corp, founded in 1981, is a Technology company based in Andover, United States. Its directors and officers file their transactions with SEC (Form 4). The last twelve months, up to 18 October 2026, brought 322 filings signed by 25 insiders.
All open-market trades in the period are sales: 206 sales worth €77.0M, by 14 insiders, with no purchase on record. No amount is published for 10 filings, which the totals therefore leave out. The largest single trade was a sale of €2.4M by Tuozzolo Claudio, published on 27 April 2026, equal to 0.021% of the market capitalisation.
Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
Across the 5,811 companies tracked on its exchange, the median is 19 filings; at 322 filings, this issuer sits above that mark. Over the whole record (from 2021), the tally stands at 2 purchases and 262 sales. The 10-K for the year ended 31 December 2025 shows 452.7 m USD of revenue and 118.6 m USD of net income.
For comparison within the same sector, see the insider buying recorded at Core Scientific, Inc./tx and Gitlab Inc. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.

About Vicor Corp
Vicor Corp. (ticker: VICR) is a U.S.-based technology company listed on the NASDAQ market in the United States. The company designs and manufactures high-performance power conversion and power delivery solutions for applications where efficiency, power density, and compact form factors are critical. Its business model is built around a modular design methodology that enables Vicor to assemble application-specific power architectures, with two main product families: Advanced Products and Brick Products. In its most recent annual filing, Vicor reports operating as a single reportable segment, supported by a centralized manufacturing base in Andover, Massachusetts, which is also the company’s headquarters.
Founded decades ago, Vicor has developed its market position through continuous innovation in product design, manufacturing processes, and proprietary semiconductor circuitry, materials, and packaging. That engineering-led culture is a central part of its competitive moat versus suppliers of power modules, power ICs, and integrated switching power supplies. The company serves technically demanding end markets, including computing, data center infrastructure, electric vehicles, industrial equipment, robotics, specialty vehicles, aerospace, and defense.

From a product standpoint, Vicor’s Advanced Products represent the strategic growth engine. Management highlights solutions for computing power delivery, including Power-on-Package concepts, as well as platforms supporting automotive electrification, including conversion architectures for 800V, 400V, and 48V systems. Brick Products remain important in more mature market segments, where Vicor focuses on profitable participation through highly customized, mass-customized offerings. This two-tier structure allows the company to address both short design-cycle opportunities and longer-life industrial applications.
Vicor’s geographic footprint is global. The company sells into the United States, Europe, and Asia-Pacific through direct customers, contract manufacturers, and distributors, and it maintains operational and commercial locations across North America, Europe, and Asia. That global reach is important because Vicor’s customer base includes large OEMs and supply-chain partners operating in multiple regions.
Recent highlights include Vicor’s latest Form 10-K for fiscal 2025, which showed continued top-line growth and a revenue mix that remains meaningfully international, with the United States and Asia-Pacific as major contributors. The filing also reinforces Vicor’s strategy of investing in Advanced Products while preserving a profitable base in its legacy product lines. For investors, VICR is best viewed as a specialized power semiconductor and power architecture company with differentiated technology, niche leadership potential, and exposure to long-term electrification and high-performance computing trends.
