SEC filingRevenue grew 13.5% YoY driven by Advanced Products and a $45M patent settlement, boosting gross margin to 57.3%.
Vicor Corporation designs, develops, manufactures, and markets modular power components and power systems for converting electrical power. The company’s offerings include a range of products for AC-DC and DC-DC conversion, with a focus on high-efficiency, high-density solutions. Vicor categorizes its portfolio into Advanced Products and Brick Products, reflecting differences in design, performance, form factor, and target applications.
The Company manages its business through two product categories: Advanced Products and Brick Products. Advanced Products contributed approximately 61.0% of total net revenues in 2025 (55.0% in 2024, 55.3% in 2023), while Brick Products contributed 39.0% (45.0% in 2024, 44.7% in 2023). Advanced Products include the Factorized Power Architecture (FPA) and related modules, and also include royalty revenue from licensing arrangements. Brick Products consist of integrated brick-format DC-DC converters and complementary components, as well as custom power solutions through Vicor Custom Power subsidiaries and VJCL in Japan.
Vicor’s Advanced Products are built around its proprietary Factorized Power Architecture (FPA), which separates the power conversion process into individual components. Key products include the PRM (Pre-Regulator Module) regulator, VTM (Voltage Transformation Module) current multiplier, and a proprietary communications controller. For high-performance computing and AI, the Company offers Power-on-Package solutions using MCD (Modular Current Driver) and MCM (Modular Current Multiplier) units, and is developing vertical power delivery solutions. Other Advanced Products serve aerospace, defense, industrial, telecom, and vehicle markets. Brick Products include a wide range of DC-DC converters, AC-DC front ends, and configurable power systems. The Company also provides design tools such as the Whiteboard tool within its Power System Designer workspace.
Vicor reaches customers through a direct sales force, authorized distributors (including Arrow, Digi-Key, Avnet, and Mouser), and Technical Support Centers (TSCs) located domestically and internationally. In Japan, sales are handled via authorized distributors or VJCL for custom products. Customers include OEMs, ODMs, and contract manufacturers across various segments. For Advanced Products, customers are concentrated in data center and hyperscaler computing, while Brick Products serve aerospace, defense, industrial, instrumentation, and transportation. The Company expects increasing customer concentration as it targets larger, high-volume customers. Exports to China and Hong Kong were $48.3 million (11.9% of revenues) in 2025, primarily Brick Products.
Advanced Products compete with large integrated device manufacturers (IDMs) offering ICs and semiconductor-based modules. These competitors have broader portfolios and greater resources, positioning Vicor’s Advanced Products as highly differentiated solutions. Brick Products compete in a fragmented market with large-scale global suppliers and smaller specialized manufacturers, with Vicor emphasizing mass customization. The Company believes its differentiated technology provides an advantageous competitive position despite having a minor overall market share.
Vicor’s strategy centers on product differentiation through superior performance (efficiency, power density, thermal management), design flexibility (Power Component Design Methodology), and compelling total cost of ownership. The Company focuses on 48V DC distribution and high-performance computing, particularly AI and machine learning applications. It plans to continue transitioning investment toward Advanced Products with a low-mix, high-volume operational model, while maintaining profitability in Brick Products via a high-mix, low-volume model. The Company also leverages its intellectual property portfolio through licensing and patent enforcement.
As of December 31, 2025, Vicor had 1,092 full-time employees (1,006 in the U.S., 86 internationally) and 23 part-time temporary employees. None are unionized or covered by a collective bargaining agreement. The Company emphasizes college recruiting, co-op programs, competitive compensation (base salary, bonuses, stock options), and benefits including health insurance, paid time off, and a 401(k) plan. Employee development is supported through in-house training and tuition reimbursement.
For the year ended December 31, 2025, Vicor Corporation reported total net revenues of $407.7 million, a 13.5% increase from $359.1 million in 2024. The growth was primarily driven by a 26.0% surge in Advanced Products revenue, which reached $248.6 million, fueled by improved market demand and higher royalty revenue. Brick Products revenue declined 1.6% to $159.1 million due to reduced market demand.
Gross margin expanded significantly to 57.3% from 51.2% in the prior year, reflecting a $75.4 million increase in gross profit. The improvement was largely attributable to a $45.0 million patent litigation settlement payment received in the second quarter of 2025, along with favorable sales volume and mix, including royalty revenue. These gains were partially offset by $3.9 million in higher freight-in and tariff spending (net of duty drawback recoveries).
Operating expenses decreased 4.2% to $177.6 million, primarily because litigation-contingency expense fell to $0 from $19.5 million in 2024 (related to the SynQor litigation). Selling, general and administrative expenses rose 2.2% to $99.0 million, while research and development expenses increased 14.0% to $78.6 million, driven by higher outside services, compensation, and supplies.
Net income soared to $118.6 million ($2.61 per diluted share) from $6.1 million ($0.14 per diluted share) in 2024. The sharp increase was aided by a $43.6 million reversal of the valuation allowance on deferred tax assets, partially offset by estimated income taxes. Income before income taxes was $94.6 million versus $10.5 million in the prior year.
Advanced Products, which includes royalty revenue, demonstrated strong momentum with 26.0% revenue growth, reflecting Vicor's strategic focus on high-growth segments such as data center and AI processor power delivery. The company noted a leadership position in powering high-performance processors for AI applications. Brick Products, serving more mature markets like aerospace/defense and industrial equipment, experienced a 1.6% revenue decline, consistent with the company's strategy of maintaining profitability in a high-mix, low-volume model while shifting investment toward Advanced Products.
The MD&A does not provide explicit forward guidance for future periods. However, management highlighted a backlog of $176.9 million at year-end 2025, up 13.8% from $155.5 million at year-end 2024, indicating continued demand. The company expects greater customer concentration over time as it focuses on large, high-volume customers. Capital expenditures were $20.3 million in 2025, and management believes cash from operations and existing cash ($402.8 million at year-end) will be sufficient to fund planned operational needs and capital equipment purchases for both the short and long term.
As of December 31, 2025, Vicor held $402.8 million in cash and cash equivalents, up from $277.3 million a year earlier. The company also maintains a long-term investment of $2.5 million (failed auction rate security). Inventory decreased to $91.3 million from $106.0 million, driven by raw material reductions. The company has no debt. Short-term deferred revenue and customer prepayments stood at $3.4 million.
Vicor reported $3.9 million in cancelable and non-cancelable capital expenditure commitments, primarily for manufacturing equipment. A significant litigation accrual of $28.3 million relates to the SynQor patent infringement judgment, including post-judgment interest. The company also has unrecognized tax benefits of $5.0 million.
In July 2024, the board authorized a new $100 million share repurchase program, replacing the prior plan. During 2025, Vicor repurchased $35.2 million of common stock, leaving $64.3 million remaining. No dividends were paid or declared. Capital expenditures totaled $20.3 million (5.0% of revenue), including $3.7 million in investment tax credit receivables. The company has no debt and no debt-related activity.
Vicor operates as a single segment. For 2025, total net revenues were $407.7 million, with 49.2% from the United States, 39.9% from Asia Pacific, and 10.5% from Europe. The company categorizes products into Advanced Products ($248.6M) and Brick Products ($159.1M). Royalty revenue contributed $57.4 million. One customer accounted for 11.1% of total revenue.
Vicor faces significant tariff exposure, with Section 301 tariffs costing $7.4M in 2025 (1.8% of revenue), a 76% increase from 2024. The company relies on duty drawback applications for recovery, but only $0.9M was recovered in 2025, and future recoveries are uncertain. International sales constitute 50.8% of revenue, with China/Hong Kong at 11.9%, making the company vulnerable to trade disputes, export controls, and geopolitical tensions. The U.S. government's Entity List expansions and evolving export controls on advanced semiconductors add further uncertainty.
Operational risks are broad: the company depends on single or limited vendors for key components, and past supply disruptions have reduced revenue. Manufacturing is concentrated at the Andover, MA facility; any prolonged interruption would materially impact results. The company is expanding capacity and bringing outsourced steps in-house, but may not achieve anticipated efficiencies. Inventory risk is elevated due to strategic stockpiling, which could lead to excess or obsolete inventory charges.
Vicor's strategy focuses on Advanced Products for large OEMs/ODMs, resulting in customer concentration—most Advanced Products revenue comes from one or a few customers. Diversification is not assured. The company faces intense competition from larger players with greater resources. Product development and sales cycles are lengthy, with no guarantee of customer adoption. The new AI integration risk factor highlights potential security, data, IP, and compliance issues from adopting AI tools.
The company's operating results are inherently volatile due to order timing, product mix, and customer concentration. Founder Dr. Vinciarelli controls 79.6% of voting power, creating governance concentration risk. The stock has low trading float and average daily volumes, contributing to price volatility. No dividends are planned. Cybersecurity and IT disruptions could impair financial reporting and operations, though no material incidents have occurred to date.
