ITEM 1.

BUSINESS

Overview

We design, develop, manufacture, and market modular power components and power systems for converting electrical power (expressed as
“watts,” and represented by the symbol “W”, with wattage being the product of voltage, expressed as “volts,” and represented by the symbol “V,” and
current, expressed as “amperes,” and represented by the symbol “I”).    In electrically-powered devices utilizing alternating current (“AC”) voltage from
a primary AC source (for example, a wall outlet), a power system converts AC voltage into the stable direct current (“DC”) voltage necessary to power
subsystems and/or individual applications and devices (known as “loads”). In many electronic devices, this DC voltage may be further converted to one
or more voltages and currents required by a range of loads. In equipment utilizing DC voltage from a primary DC source (for example, a battery) or a
secondary source (such as an AC-DC converter), the initial DC voltage similarly may require further conversion. A power system most commonly
incorporates four voltage conversion functions: transformation, isolation, rectification, and regulation.

Transformation refers to the process of increasing or decreasing an AC voltage; isolation refers to the electrical separation, for safety, of primary

and secondary voltages in a transformer; rectification refers to the process of converting a voltage from AC to DC and/or from DC to AC; and regulation
refers to the process of providing a near constant voltage under a range of line and load conditions. Because numerous applications requiring different
voltages, currents, and varied power ratings may exist within an electronically-powered device, and system power architectures themselves vary, we
offer an extensive range of products and accessories in numerous application-specific configurations. We believe our product offering is among the most
comprehensive in the market segments we serve.

Our strategy, competitive positioning, and product offerings are all based on highly differentiated product performance, reflecting our anticipation

of the evolution of system power architectures and customer performance requirements. Since the company was founded, we have pursued continuous
innovations in product design and achievements in product performance, largely enabled by our focus on the research and development of advanced
technologies and processes, often implemented in proprietary semiconductor circuitry, materials, and packaging. Reflecting this strategy, we categorize
our offerings as either “Advanced Products” or “Brick Products,” generally based on design, performance, and form factor considerations, as well as the
range of evolving applications for which the products are appropriate.

Our competition varies, depending on the market segment and application. Generally, we compete with developers and manufacturers of
integrated circuits and semiconductor-based modules when addressing the needs of customers in enterprise computing and other market segments with
implementations of our proprietary Factorized Power ArchitectureTM (“FPA”) using Advanced Products. In contrast, we generally compete with
manufacturers of integrated power supplies when addressing the needs of customers, across a wide range of market segments, implementing
conventional power systems architectures (e.g., Centralized Power Architecture (“CPA”), Distributed Power Architecture (“DPA”), and Intermediate
Bus Architecture (“IBA”)) using Brick Products.

Our website, www.vicorpower.com, sets forth detailed information describing our products, the applications for which they may be used, and our

suite of design tools. The information contained on our website is not a part of, nor incorporated by reference into, this Annual Report on Form 10-K
and shall not be deemed “filed” under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

We are headquartered in Andover, Massachusetts, where our manufacturing facility is located. Our wholly-owned subsidiary, VICR Securities

Corporation, also is located in Andover, Massachusetts. Our other domestic offices are located in Santa Clara, California, Lombard, Illinois, and
Lincoln, Rhode Island. Our two Vicor Custom PowerTM subsidiaries, Freedom Power Systems, Inc. and Northwest Power, Inc., are located in Cedar
Park, Texas, and Milwaukie, Oregon, respectively.

We have established individual subsidiaries or unincorporated branch offices outside of the United States, which we call Technical Support
Centers (“TSCs”), to conduct preparatory and auxiliary services in support of the Company. Vicor Japan Company, Ltd. (“VJCL”), our 92.5%-owned
Japanese subsidiary, which is engaged in sales and customer support activities exclusively for the sale of certain products customized by VJCL for the
Japanese market, is headquartered in Tokyo, Japan.

In August 2020, our subsidiary, VLT, Inc., which was a vehicle for licensing technologies, was merged with and into the Company. In June 2019,

our subsidiary, VI Chip Corporation (“VI Chip”), was merged with and into the Company, and its operations and personnel were reassigned. In
December 2019, we closed Vicor B.V., a wholly-owned subsidiary incorporated in the Netherlands, which provided logistical and administrative support
for certain sales in the European Union.

Our remaining subsidiaries and their legal domicile are set forth in Exhibit 21.1 to this Annual Report on Form 10-K. The activities of all of the

above named entities are consolidated in the financial statements presented herein.

Vicor was incorporated in Delaware in 1981, and we completed an initial public offering in May 1991. The Company has two classes of common

stock outstanding: shares of our “Common Stock,” listed on The NASDAQ Stock Market under the ticker symbol VICR, and shares of our Class B
common stock, which are not subject to registration pursuant to the Exchange Act and are not listed on any exchange.

Our Strategy

Our strategy emphasizes demonstrable product differentiation and a value proposition based on competitively superior solution performance,
advantageous design flexibility, and a compelling total cost of ownership (“TCO”). Since the Company was founded, our competitive position has been
maintained by continuous innovations in product design and achievements in product performance, largely enabled by our focus on the research and
development of advanced technologies and processes, often implemented in proprietary semiconductor circuitry, materials, and packaging. Many of our
products incorporate patented or proprietary implementations of high-frequency switching topologies, which enable the design of power system
solutions more efficient and much smaller than conventional alternatives. This efficiency and small size is enabled by our proprietary switching circuitry
and magnetic structures, as well as our use of highly differentiated packaging.    

Power system performance is based primarily on conversion efficiency (i.e., the ratio of output power (i.e., watts) to input power) and power
density (i.e., the amount of output power divided by the volume of the power system). Higher efficiency and density contribute to superior thermal
performance, as the by-product of power conversion and distribution is heat, which must be dissipated in order to assure the performance of the power
system solution itself and the overall system to which it is delivering power. Power system performance also is based on the electrical characteristics of
the power system (and their effect on and compatibility with the customer’s application). Important electrical characteristics include transient
responsiveness (i.e., the reaction of a power system to a sudden change in voltage or current levels) and noise profile (i.e., the level of electromagnetic
interference created by power conversion). We believe the superior performance of our power systems is the most important element of our
differentiation strategy.

Our strategy complements performance superiority with design flexibility (i.e., ease of use), as our products can be utilized individually or
combined, given their level of integration, to create power system solutions specific to a customer’s precise needs. We articulate this positioning through
our “Power Component Design Methodology,” an element of our differentiation strategy, which is our approach to providing our customers the modular
products, design tools, and engineering support to enable the rapid design of advanced power system solutions by customers and, thereby, accelerate
their own product development cycles. Our value proposition is supported by a compelling TCO, representing the cost of acquiring and operating a
power system over its useful life, driven by competitive product pricing, high reliability, and demonstrably lower electricity costs.

Our earliest market focus was on telecommunications infrastructure, which uses a standard DC distribution voltage of 48V (nominally 48V to

54V), the highest distribution voltage that meets Safety Extra-Low Voltage (“SELV”) standard requirements, while leaving sufficient margin for over-
voltage protection circuits. While we offer products addressing other DC voltage standards (e.g., 380V for power distribution in data centers, 110V for
rail applications, 28V for military and avionics applications, and 24V for industrial automation) and a broad range of customer requirements, we
consider our core competencies to be associated with 48V distribution, which offers numerous inherent cost and performance advantages over lower
distribution voltages, while remaining within the 60V SELV safety limit.

Our product portfolio also includes families of “front-end” devices, which address applications requiring the transformation of AC voltages to

regulated DC voltages. Examples of such applications include powering data center server racks, large-scale LED lighting, specialized laboratory,
diagnostic, and test equipment, small-cell wireless base stations, and higher power equipment for defense and industrial use.

Reflecting our strategy, we categorize our offerings as either Advanced Products or Brick Products, generally based on design, performance, and

form factor considerations, as well as the range of evolving applications for which the respective categories are appropriate. The Advanced Products
category consists of our most innovative products, which are used to implement our proprietary distribution architecture, FPA, a highly differentiated
approach to power distribution that enables flexible, rapid power system design using individual components optimized to perform a specific function.
The Brick Products category largely consists of integrated power converters (i.e., “bricks”), incorporating multiple conversion stages, used in
conventional power systems architectures including CPA, DPA, and IBA.

Given the growth profiles and performance requirements of the market segments served with Advanced Products and Brick Products, our strategy

involves a transition in organizational focus, emphasizing investment in Advanced Products design and manufacturing, targeting high growth market
segments with a low-mix, high-volume operational model, while maintaining a profitable business in mature market segments we serve with Brick
Products with a high-mix, low-volume operational model.

Our Products

Reflecting our Power Component Design Methodology, we offer a comprehensive range of modular building blocks enabling rapid design of a
power system specific to a customer’s precise needs. Based on design, performance, and form factor considerations, as well as the range of evolving
applications for which the products are appropriate, we categorize our product portfolios as either Advanced Products or Brick Products. We also sell a
range of electrical and mechanical accessories for use with our products.

Advanced Products

We continue to invest in the research and development of power system technologies and product concepts addressing two accelerating trends, the

first toward higher required conversion efficiencies, and the second toward more and diverse on-board voltages, higher performance demands of
complex loads, and, in particular, higher current requirements of those loads. These trends are most visible in the microprocessor-based applications we
target with Advanced Products, for which energy consumption, energy efficiency, processor performance, and computing density are critical priorities.
Recognizing the performance and scale limitations of conventional power distribution architectures and products, we introduced FPA and a range of
enabling products incorporating our latest advances in power distribution concepts, switching topologies, materials, and packaging.

FPA, which is focused on, but not limited to, 48V DC distribution solutions, increases power system conversion efficiency, density, and power

delivery performance by “factorizing” (i.e., separating) the power conversion process into individual components, reducing the design limitations,
thermal management challenges,

4

 
Table of Contents

and scaling trade-offs associated with conventional architectures for DC voltage distribution. All such architectures follow a sequence whereby a DC
voltage is first transformed, or reduced, and that lower voltage subsequently conducted (i.e., “bussed”) across the circuit to the “load” (i.e., the point of
use), where the voltage is regulated and lowered once more, to the required operating voltage of the load. In a FPA implementation, the sequence is
reversed. Regulation occurs first, and the regulation module can be placed in the optimal position for space utilization and thermal management. A
regulated voltage approaching 48V is bussed across the circuit to the transformation module, which performs what we refer to as current multiplication,
adjacent to the load. Bussing high voltage minimizes the current levels across the circuit, thereby minimizing the potential for distribution losses and
reducing the volume of the conduit (e.g., the copper wire). Placing the relatively low noise, low heat current multiplication module adjacent to the load
further minimizes the potential for distribution losses associated with bussing a low operating voltage to the load and reduces the potential influence of
the power system on the performance of the load.

A typical FPA implementation for delivering 48V DC from a server backplane to a 1.0V microprocessor would consist of three modules: a PRM™

(Pre-Regulator Module) regulator, a VTM™ (Voltage Transformation Module) current multiplier, and a proprietary communications controller. In
contrast, a commodity IBA design for delivering 48V DC from a server backplane to a 1.0V microprocessor requires an additional conversion stage, to
reduce 48V to 12V, and, at the point of load, a voltage regulation module (i.e., a “VRM” consisting of multiple switching regulators, each representing a
phase and consisting of two switching transistors, one or more capacitors, and an inductor, with the transistors switched by pulse width modulation
controller). For a 200W two stage, multiphase application, a 12V commodity IBA implementation would require an intermediate bus converter, to
reduce 48V to 12V, and a VRM solution consisting of parallel phases (i.e., multiple switching regulators) to reduce and regulate the current for use at
1.0V by the microprocessor. Such a commodity IBA implementation requires a significantly higher component count, consumes more motherboard area,
requires more copper conduit, generates more heat due to switching and distribution losses, offers inferior dynamic response, and can be meaningfully
less efficient than a 48V FPA implementation.

The advantages of FPA over legacy power distribution architectures are most evident in high performance computing applications. Our
“Power-on-Package” power system solutions meet the computational performance requirements of artificial intelligence (“AI”). The microprocessors
typically used in AI, particularly in more computationally demanding “machine learning” or “training” applications, are graphics processing units
(“GPUs”) and custom application-specific integrated circuits (“ASICs”). Unlike central processing units (“CPUs”), which are designed for serial
execution of complex and broad instruction sets, GPUs and AI ASICs are designed for massively parallel (i.e., concurrent) processing of repetitive
transactions or calculations. As such, GPUs and AI ASICs generally operate at processing frequencies requiring the higher levels of average and peak
current delivered by our FPA-based solutions. Our most popular Power-on-Package solution, consists of one MCD© (Modular Current Driver) unit,
providing high-bandwidth, low-noise regulation, and two MCM© (Modular Current Multiplier) units, providing high performance current multiplication.
Power-on-Package delivers unprecedented current levels to GPUs and AI ASICs, in part due to the placement of the MCMs directly on the substrate
onto which the processor is mounted, thereby minimizing distribution losses associated with high current levels. Placement of MCM units on the
substrate also reduces the number of GPU or ASIC processor substrate pins required for power, allowing for their use by other functions (e.g., memory
input/output (“I/O”)). This three-module laterally-mounted Power- on-Package configuration, powering an AI accelerator card requiring 350W, delivers
0.7V, 650A average current, and up to 1,200A peak current to the GPU or AI ASIC, with superior transient response and unmatched power density.

We are unaware of any competitive solution for AI acceleration offering the power system performance and density of Power-on-Package, as
IBA-based solutions must increase the number of conversion phases to reach high current levels, thereby increasing component count and motherboard
area used, which contributes to higher switching and distribution losses, inferior dynamic response, and associated heat generation.

Table of Contents

Our latest innovation for powering processors is vertical power delivery, which involves mounting our highest-performance solutions on the
underside of the motherboard, opposite the GPU or AI ASIC, thereby enabling a further reduction in distribution losses at the load, yielding higher
efficiency and unprecedented power density. Vertically-mounting the solution allows unrestricted access to microprocessor input/output I/O pins on the
top side of the motherboard, thereby improving I/O speed and memory access, which are a priority for GPUs and AI ASICs in AI applications. We are in
the final development stages of our vertical power delivery solutions and expect to be shipping released products to customers in 2022.

Our proprietary technologies enable us to offer a range of Advanced Products, in various package formats across functional families, applicable to

other market segments and power distribution architectures other than FPA. Within computing, these market segments include AC to DC voltage
conversion and DC voltage distribution in server racks and high voltage conversion across datacenter infrastructure. We also offer Advanced Product
power system solutions for aerospace and aviation (e.g., for use in satellites, unmanned aerial vehicles, and various airframes, including battery-powered
aircraft, for which small size, light weight, and design flexibility are advantageous); defense electronics (e.g., for use in airborne, seaborne, or field
communications and radar, for which reliability in harsh environments is a priority); industrial automation, instrumentation, and test equipment (e.g., for
use in robotics and semiconductor testing, for which high power levels and precision performance are required); solid state lighting (e.g., for use in large
scale displays and signage, for which, again, small size, light weight, and design flexibility are advantageous); telecommunications and networking
infrastructure (e.g., for use in high-throughput data distribution and pole-mounted small-cell base stations); and vehicles (e.g., in autonomous driving
applications, electric vehicles, and hybrid electric vehicles).

Annual revenue associated with the sale of Advanced Products was approximately 47.4%, 35.8%, and 28.6% of the Company’s consolidated

revenue for the years ended December 31, 2021, 2020, and 2019, respectively. Advanced Products revenue grew in 2021 primarily due to cloud
computing infrastructure growth and the further adoption of AI systems within the cloud.

We anticipate the percentage of periodic revenue associated with the sale of Advanced Products will increase in the future, given our strategic and

organizational focus and the relatively higher expected growth of the market segments we serve.

Brick Products

Brick-format converters provide the integrated transformation, rectification, isolation, regulation, filtering, and/or input protection necessary to

power and protect loads, across a range of conventional power architectures. We offer a wide range of brick-format DC-DC converters, as well as
complementary components providing AC line rectification, input filtering, power factor correction, and transient protection. Wide ranges of input
voltages, output voltages, and output power are offered, allowing end users to select components appropriate to their individual applications. The
products differ in dimensions, temperature grades, maximum power ratings, performance characteristics, pin configuration, and, in certain cases,
characteristics specific to the targeted market.

We also integrate these converters and components into complete power systems representing standard or custom AC-DC and DC-DC solutions

for our customers’ power needs. We refer to such standard products as our “Configurable” product line, while our two Vicor Custom Power subsidiaries
design, sell, and service custom power system solutions.

We market our standard Brick Products emphasizing “mass customization,” using highly automated, efficient, domestic manufacturing to serve

customers with product design and performance requirements, across

6

 
Table of Contents

a wide range of worldwide market segments, which could not be met by high-volume oriented competitors. We focus on distributed power
implementations, for which our brick-format products are well-suited, in market segments such as aerospace and defense electronics, industrial
automation, industrial equipment, instrumentation and test equipment, and transportation (e.g., rail). Our customers range from independent
manufacturers of highly specialized electronic devices to larger original equipment manufacturers (“OEMs”) and their contract manufacturers. Some of
our Brick Product lines have been in production for over a decade, reflecting the maturity of the markets we serve, the long-established relationships we
have with many customers, and the long-standing suitability of our products to demanding applications.

Annual revenue associated with the sale of Brick Products, representing the sum of sales to third-parties of the products previously sold under the

former Brick Business Unit operating segment during periods prior to the second quarter of 2019, inclusive of such sales of our Vicor Custom Power
and VJCL subsidiaries, was approximately 52.6%, 64.2%, and 71.4% of the Company’s consolidated revenue for the years ended December 31, 2021,
2020, and 2019, respectively.

Customers and Backlog

The applications in which our Advanced Products and Brick Products are used are typically in the higher-performance, higher-power segments of

the market segments we serve. With our Advanced Product lines, our customers are concentrated in the data center and hyperscaler segments of
enterprise computing, in which our products are used for voltage distribution on server motherboards, in server racks, and across datacenter
infrastructure, although we also target applications in aerospace and aviation, defense electronics, industrial automation, instrumentation, test equipment,
solid state lighting, telecommunications and networking infrastructure, and vehicles (notably in the autonomous driving, electric vehicle, and hybrid
vehicle niches of the vehicle segment). With our Brick Product lines, we serve customers concentrated in aerospace and defense electronics, industrial
automation, industrial equipment, instrumentation and test equipment, and transportation (notably in rail and heavy equipment applications). With our
strategic emphasis on larger, high-volume customers, we expect to experience a greater concentration of sales among relatively fewer customers.

As of December 31, 2021, the Company’s order backlog was approximately $345,594,000, compared to $147,550,000 as of December 31, 2020.
Backlog, as presented here, consists of orders for products for which shipment is scheduled within the following 12 months, subject to our scheduling
and cancellation policies.

The lead times between receipt and acceptance of an order and our shipment of the product have increased, largely as a consequence of the

COVID-19 pandemic. The COVID-19 pandemic has caused widespread delays in production and delivery. In response, during the second quarter of
2021, we extended our quoted lead times for delivery to customers to 26-32 weeks depending on the product family. Customer demand has outstripped
capacity and semiconductor suppliers have allocated capacity. In addition, suppliers have increased component pricing. In the second quarter of 2021,
we increased our prices in response to component cost increases that could no longer be absorbed.

A portion of our revenue in any quarter is, and will continue to be, derived from “turns” volume, representing either orders booked and shipped in
the same quarter or orders for which customers have requested accelerated delivery from a later quarter to the current quarter. This volume generally has
been associated with orders for Brick Products. Over the past four years, the volume of orders booked and shipped within a quarter has declined steadily,
reflecting lengthened delivery lead times across the electronics industry. However, over the same period, the volume of orders for which customers have
requested accelerated delivery has increased, which we believe to be a reflection of improved conditions in many of the market segments we serve with
Brick Products. An additional influence on turns volume has been our transition to larger OEM customers, which typically schedule large volumes for
delivery over multiple quarters and frequently reschedule deliveries for either earlier or later shipment. Average quarterly turns volume was
approximately 19% of 2021 revenue, approximately 14% of 2020 revenue, and approximately 27% of 2019 revenue.

Competition and Market Characteristics

The competitive characteristics of the markets we serve with Advanced Products and Brick Products can differ significantly. For example, in the

higher-performance segments of computing we serve, our Advanced Products most often compete with solutions offered by large integrated device
manufacturers (“IDMs”), which offer integrated circuits (“ICs”) and semiconductor-based modules. These IDMs generally offer far broader product
portfolios, possess far greater global manufacturing and support resources, and have the ability to aggressively price their products to defend market
share. Accordingly, Advanced Products are positioned as highly differentiated alternatives to commodity solutions for customers seeking high levels of
performance. The customers we serve with Advanced Products, typically on a direct basis, are in market segments generally characterized by an
emphasis on product performance differentiation, a compelling TCO, relatively extended and highly competitive design cycles, and product life cycles
of generally less than three years. In contrast, the Brick Products competitive landscape is relatively fragmented, with large-scale, low-cost global
suppliers of commodity solutions and many smaller manufacturers focused on specialized products or narrowly defined market segments or
geographies. The market segments we serve with Brick Products, typically through sales representatives and distribution partners, generally are
characterized by relatively short design cycles, relatively long (i.e., greater than three years) product life cycles, and, given the maturity of many market
segments and applications, degrees of commoditization and price competition. As such, Brick Products are positioned with an emphasis on mass
customization, through which we offer products with specific features and performance profiles typically not available from catalog-oriented
competitors.

The size and growth characteristics of the markets we serve with Advanced Products and Brick Products also can differ significantly, and the
range and quality of market data is problematic, making summary statements about these markets challenging. We believe our Advanced Products
generally compete with power modules and power ICs developed and manufactured by IDMs and other fabless vendors of power semiconductors. We
believe our Brick Products generally compete with similarly integrated switching power supply products developed and manufactured by large global
competitors and a fragmented group of small regional competitors. The switching power supply market can be segmented by product type (i.e., DC-DC
converters, AC-DC converters, and DC-AC inverters), by output power levels, and by numerous vertical markets (i.e., industry-specific applications).

For 2021, exports to China and Hong Kong were approximately $98,700,000, representing approximately 27.5% of total revenue and an
approximately 6.1% increase over the 2020 total of approximately $93,000,000. We believe this increased volume was primarily associated with the
stimulus spending of the Chinese government, although we also believe an unquantifiable amount of this volume may have been associated with
accelerated purchasing by customers anticipating further deterioration of the trade relationship between China and the U.S. Our belief is based on input
from our distribution partners in China, as well as the mix of products exported over the past three years. Exports to China and Hong Kong peaked at
approximately $109,000,000 in 2018, but that figure included approximately $50,000,000 of exports of Advanced Products to OEM customers and their
contract manufacturers. The majority of the programs associated with this amount were transferred to other countries, as contract manufacturers for the
majority of production programs in China and Hong Kong sought to avoid inbound and outbound tariffs. Current exports to China and Hong Kong are
heavily oriented toward Brick Products for industrial and rail applications, as well as certain aerospace and defense electronics applications permitted
under U.S. export control regulations (our products are designated EAR99 commodities under the Export Administration Regulations of the U.S.
Department of Commerce and are not subject to export licenses).

Despite our minor share in the overall merchant market and the competitive presence of numerous, far larger vendors in the market segments we

serve with both Advanced Products and Brick Products, we believe we maintain an advantageous competitive position in those market segments.
Notably, we believe we have the largest share of 48V power distribution opportunities within the segments of the computing market segments we serve.
However, numerous competitors across these market segments have significantly greater engineering,

financial, manufacturing, and marketing and sales resources, as well as longer operating histories and longer customer relationships than we do.

Marketing and Sales

We reach and serve customers through several sales channels: a direct sales force; a network of independent sales representative organizations in

North America; independent, authorized non-stocking distributors in Europe and Asia; and four authorized stocking distributors world-wide: Arrow
Electronics, Inc., Digi-Key Corporation, Future Electronics Incorporated, and Mouser Electronics, Inc. All sales channels are supported by regional
TSCs, each offering application engineering and sales support for our channel partners. Domestic TSCs are located in: Andover, Massachusetts;
Lombard, Illinois; and Santa Clara, California. International TSCs are located in: Beijing, China; Hong Kong, China; Shanghai, China; Shenzhen,
China; Munich, Germany; Bangalore, India; Milan, Italy; Tokyo, Japan; Seoul, South Korea; Taipei, Taiwan (Republic of China); and Camberley,
United Kingdom. Customers do not place purchase orders with TSCs, but do so directly with the Company or with our channel partners. In Japan,
customers place purchase orders with authorized distributors or, for certain custom products, VJCL.

We generally sell our products on the basis of our standard terms and conditions, and we most commonly warrant our products for a period of two
years. Effective January 1, 2017, we extended the warranty period to three years for a range of H Grade, M Grade, and MI Family DC-DC products sold
after that date. In a limited number of circumstances, we have entered into supply contracts with certain high-volume customers calling for extended
warranty terms. With our distribution partners, we also enter into contracts providing for our product warranties to transfer to the end customer upon
final sale of our product(s) by the distributor.

Because of the technically complex nature of our products and the applications they address, we maintain an extensive staff of Field Applications
Engineers to support our own sales and customer support activities, as well as those of our channel partners. Field Application Engineers, based in our
TSCs, provide direct technical support worldwide by reviewing new applications and technical matters with our channel partners in support of existing
and potential customers. Product Development Engineering is located in our Andover headquarters, where our Product Development Engineers support
the Field Application Engineers assigned to all of our TSCs.

Our direct sales force focuses on higher-volume opportunities involving Advanced Products with global OEMs (and the Original Design
Manufacturers (“ODMs”) and contract manufacturers serving these OEMs). Because of the high level of product differentiation and the increasing
complexity and challenges of customer requirements, we have experienced, and may continue to experience, extended design cycles before production
orders are received.    

We also reach customers through the electronic commerce capabilities of our website, www.vicorpower.com. Registered, qualified customers in

the United States, Canada, and certain European countries are able to purchase selected products online.

Our web-based resources are an important element of our efforts to interact with and support customers. Within our website, the Power System

Designer workspace of tools and references allow engineers to select, architect, and implement power systems using our products. Our highly
differentiated WhiteboardTM tool allows users to configure and analyze their own power system designs or those from an extensive library of designs
addressing a wide range of applications. Users can modify the operating condition for each component of their design to match the intended application
and perform efficiency and loss analysis of individual components and the full power system. We continue to enhance and expand the range and
capabilities of engineering tools we make available online to customers and prospective customers.

As stated, our strategy involves maintaining high levels of customer engagement and support for design and engineering, which has resulted in

significant expansion of our sales and application engineering infrastructure

Table of Contents

over historical levels, notably across Asia. We incurred approximately $46,602,000, $43,396,000, and $43,387,000 in marketing and sales expenses in
2021, 2020, and 2019, respectively, representing approximately 13.0%, 14.6%, and 16.5% of revenues in 2021, 2020, and 2019, respectively.

Manufacturing, Quality Assurance, and Supply Chain Management

Our manufacturing facility, of approximately 320,000 square feet, is located in Andover, Massachusetts, where we are headquartered. In this
facility, we manufacture Brick Products, with the exception of custom products produced by our Vicor Custom Power and VJCL subsidiaries, and
Advanced Products, with the exception of certain products manufactured, packaged, and tested by third party wafer foundries and packaging contractors
in the United States and Asia.

Our primary manufacturing processes involve steps common to automated assembly of electronics devices. We also have developed and employ

proprietary manufacturing processes that contribute to the differentiated performance of our devices, including the innovative electroplating of our
SM-ChiP© modules discussed below. During the third quarter of 2020, we began construction of an addition of approximately 90,000 square feet to our
existing manufacturing facility. We initially planned on taking occupancy of the addition in the first half of 2021, but due to a variety of factors
including the effect of the global pandemic, we now plan to take occupancy of this addition during the first half of 2022.

As previously disclosed, we partner with a highly-specialized third-party developer of electroplating processes and equipment, which performs
certain elements of our proprietary manufacturing process using equipment designed by the developer. In 2019 and 2020, we entered into service and
equipment purchase agreements with this partner. While commodity electroplating services are available from numerous alternate providers, we entered
into these agreements due to the level of our collaboration to date with the partner in the refinement of certain proprietary processes we employ and our
joint commitment to environmentally sound manufacturing minimizing toxic waste. Approximately one-half of the addition to our manufacturing
facility will be allocated to installation of highly-automated equipment scheduled to be delivered by the partner, beginning in the first half of 2022,
which equipment is expected to enable the vertical integration of all manufacturing process steps for SM-ChiP modules. We expect the pre-production
qualification of this installed equipment will begin late during the first half of 2022, with production volumes to follow later in the year. We have relied
on this partner’s services to meet our requirements for SM-ChiP production to date, but we expect to have fully-operational production capabilities on
site. The initial planned installation dates for this equipment in 2021 were, in some cases, delayed due to a variety of factors including the effect of the
global pandemic.

We continue to make investments in automated manufacturing equipment, particularly for expansion of production capacity for Advanced
Products. During 2019, through investment in additional capital equipment, we increased our total manufacturing capacity in our Andover facility by
approximately 35%. The addition of manufacturing lines and the vertical integration of electroplating are expected to increase our Advanced Products
capacity by an additional 100%, based on additional machine capacity and accelerated cycle times due to vertical integration. During 2020, we began
construction of a two-story addition to our Andover manufacturing facility that is intended to expand the Advanced Products production area by
approximately 90,000 square feet. Construction and occupancy were delayed from 2021 to 2022. We have taken occupancy of the expansion and
equipment installation is underway.

Product quality and reliability are critical to our success and, as such, we emphasize quality and reliability in our design and manufacturing
activities. We follow industry best practices in manufacturing and are compliant with ISO 9001 certification standards (as set forth by the International
Organization for Standardization). Our quality assurance practices include rigorous testing and, as necessary, burn-in and temperature cycling (i.e.,
extended operation of a product to confirm performance) of our products using automated equipment. Incoming components, assemblies, and other parts
are subjected to several levels of inspection procedures, and we maintain robust data on our raw material inventories in order to support our quality
assurance procedures.

Table of Contents

Components and materials used in our products are purchased from a variety of domestic and international vendors. Generally, the global
electronics supply chain continued to be impacted by the COVID-19 pandemic in 2021. Lead times for delivery of certain raw materials remain
extended, particularly as a result of the impacts of new COVID-19 variants. Most of these raw materials are available from multiple sources, whether
directly from suppliers or indirectly through distributors, and, during 2021 we continued to opportunistically expand certain raw material inventories to
offset the uncertainties associated with availability and lead times.

Certain Advanced Products and semiconductor devices used in our production are manufactured by a limited number of wafer foundries, with

packaging and test services provided by a limited number of third parties. We rely on these wafer foundries and packaging and test providers for supply
continuity of these critical semiconductor devices. Throughout 2021, the semiconductor test and packaging segment of the global electronics supply
chain experienced well-publicized capacity constraints, and, as a result, we have continued to experience unpredicted delays in receipt of certain
semiconductor components from our packaging and test vendors. To date, these delays have not had a material impact on our ability to meet customer
delivery requirements. In response to current schedule uncertainties, we are seeking alternate providers of packaging and test services and may further
increase inventory levels for these semiconductor components, when possible. Should these capacity constraints continue or worsen and we are unable
to obtain the necessary volumes of required semiconductor components, we may not be able to meet delivery commitments for certain customers and
may not be able to reduce delivery lead times for the foreseeable future.

To date, we have not experienced material delays or reduced raw material availability as a result of trade disputes between the U.S. and China,

including the imposition in 2018 of import tariffs under the provisions of Section 301 of the Trade Act of 1974 (19 U.S.C. § 2411) (“Section 301
Tariffs”) on certain Chinese goods imported into the United States. For the year ended December 31, 2021, costs associated with tariffs totaled
approximately $6,678,000, a decrease of 8% over the $7,259,000 in costs incurred for the year ended December 31, 2020. We continue to assess the
impact of these costs and are actively evaluating alternative sources of raw materials. We also have filed “duty drawback” applications with U.S.
Customs and Border Protection for the recovery of tariffs paid on raw materials used to produce products we subsequently exported. We have recovered
$676,000 through December 31, 2021, however, we are not able to estimate the amount or timing of any additional recoveries, and there can be no
assurance that there will be any additional recoveries.

Intellectual Property

Our competitive positioning has been, and will continue to be, supported by our long-standing commitment to research and development of power

distribution architectures, power conversion technologies, advanced packaging and manufacturing, and innovative approaches to solving customer
problems. Our research and development activities have resulted in important domestic and foreign patents protecting our products and enabling
technologies, as well as proprietary trade secrets associated with our use of certain components and materials of our own design and proprietary
manufacturing, packaging, and testing processes. We incurred approximately $53,114,000, $50,916,000, and $46,588,000 in research and development
expenses in 2021, 2020, and 2019, respectively, representing approximately 14.8%, 17.2%, and 17.7% of revenues in 2021, 2020, and 2019,
respectively.

We believe our intellectual property affords advantages by building fundamental and multilayered barriers to competitive encroachment upon key

features and performance benefits of our principal product families. Our patents cover the fundamental switching topologies used to achieve the
performance attributes of our converter product lines; converter array architectures; product packaging design; product construction; high frequency
magnetic structures; and automated equipment and methods for circuit and product assembly.

As of December 31, 2021, in the United States, we have been issued 121 patents having expirations scheduled between 2022 and 2038 and have

filed a number of patent applications which are still pending, many of which are to issue as patents in 2022. We have vigorously protected our rights
under these patents and will

11

 
Table of Contents

continue to do so. Although we believe patents are an effective way of protecting our technology, there can be no assurances our patents will prove to be
enforceable in any given jurisdiction.

In addition to generating revenue from product sales, we seek to license our intellectual property. In granting licenses, we generally retain the right

to use our patented technologies and manufacture and sell our products in all licensed geographic areas and fields of use. Revenues from licensing
arrangements have not exceeded 10% of our consolidated revenues in any of the last three fiscal years.

Human Capital Management

High-caliber employees are important to achieving Vicor’s mission of providing the highest performance power solutions to meet the

requirements of the most demanding applications. In order to maintain leadership in power systems design in a highly competitive employment market,
attracting and retaining the best team worldwide is critical. Accordingly, we offer compelling compensation and benefits, foster a culture of innovation
in which employees are empowered to do (and are rewarded for) their best work, and seek to establish Vicor as a meaningful contributor to the
communities in which we operate, further strengthening the bonds between employees and the Company.

As of December 31, 2021, we had 1,027 full-time employees, of which 924 were in the U.S. and 103 were in our international locations. None of

our employees are represented by a labor union or covered by a collective bargaining agreement.

We recruit from colleges and universities, with a focus on specific engineering disciplines. In collaboration with certain universities, we maintain a

student “Co-Op” program, whereby qualifying undergraduate and graduate students work at our Andover facilities for one or two semesters, receiving
course credit towards their graduation. In recent years, we have had as many as approximately two dozen participants per semester, with a substantial
percentage of participants receiving offers of full-time employment.

Our compensation program is designed to attract and reward talented individuals who possess the skills necessary to support our business
objectives, assist in the achievement of our strategic goals, and create long-term value for our stockholders. We provide employees with compensation
packages that include a competitive base salary or wage rate and benefits such as life and health (medical, dental, and vision) insurance, supplemental
insurance, paid time off, paid parental leave, and a 401(k) plan (with Company match). Generally (and subject to local laws), new employees are
awarded non-qualified options for the purchase of the Company’s common stock. Depending on an employee’s role, he or she may be eligible for annual
incentive bonuses and periodic awards of non-qualified options based on the performance of the Company and that of the employee. We believe a
compensation program with appropriate long-term incentives aligns employee and stockholder interests in increasing the value of the Company.

We emphasize and encourage employee development and training. To empower employees to reach their potential, we provide a range of
development programs and opportunities, including in-house training programs and tuition reimbursement for those pursuing outside certification or
degrees.

We seek to support the communities in which we operate and believe this commitment contributes to our efforts to attract and retain employees.

We support our employees in volunteer initiatives. We also partner with a range of non-profit organizations and have had notable success in our
collaboration for over two decades with the Crest Collaborative of Methuen, MA, a local advocacy agency, in providing enriching employment
opportunities for individuals with disabilities.

ITEM 1A.

RISK FACTORS

This Annual Report on Form 10-K contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Exchange Act. Actual results could differ materially from those projected in the forward-looking statements as a result
of, among other factors, the risk factors set forth below.

Operational Risks

Our future operating results are difficult to predict and are subject to fluctuations.

Our operating results, including revenues, gross margins, operating expenses, and net income (loss), have fluctuated on a quarterly and annual

basis. Our strategic focus on higher volume opportunities with OEMs, ODMs, and contract manufacturers has caused the actions of a relative few such
customers to disproportionately influence our operating results. Unanticipated delays in purchase orders from, and shipments to, certain large customers
have resulted in lower than expected revenue. Similarly, our strategic focus on the development of market-leading technologies and manufacturing
processes, often implemented in proprietary semiconductor circuitry, materials, and packaging, has exposed the Company to the risks and costs of delays
in such development and the use of a relatively few number of suppliers of proprietary circuits and materials or providers of proprietary services.

Despite recent profitability trends, we cannot predict if we will maintain sustained profitability. Our future operating results may be materially

influenced by a number of factors, many of which are beyond our control, including:

•

•

•

•

•

•

•

•

•

•

  changes in demand for our products and for our customers’ end-products incorporating our products, as well as our ability to respond

efficiently to such changes in demand, including changes in delivery lead times and the volume of product for which orders are accepted
and the product shipped within an individual quarter;

  our ability to manage our supply chain, inventory levels, and our own manufacturing capacity or that of third-party partners, particularly in
the event of delays or cancellation of significant customer orders or in the event of delays or cost increases associated within our supply
chain;

  our ability to effectively coordinate changes in the mix of products we manufacture and sell, while managing our ongoing transition in

organizational focus and manufacturing infrastructure to Advanced Products from Brick Products;

  our ability to provide and maintain a high level of sales and engineering support to an increasing number of demanding, high volume

customers;

  the ability of our third party suppliers and service subcontractors to provide us sufficient quantities of high quality products, components,

and/or services on a timely and cost-effective basis;

  the effectiveness of our ongoing efforts to continuously reduce manufacturing costs and manage operating expenses;

  our ability to utilize our manufacturing facilities and personnel at efficient levels, maintaining sufficient production capacity and necessary

manufacturing yields;

  our ability to plan, schedule, and execute capacity expansion, including the anticipated addition in 2022 of approximately 90,000 square

feet to our Andover manufacturing facility;

  the timing of our new product introductions and our ability to meet customer expectations for timely delivery of fully qualified products;

  the timing of new product introductions or other competitive actions (e.g., product price reductions) by our competitors;

•

•

  the ability to hire, retain, and motivate qualified employees to meet the demands of our customers;

  intellectual property disputes;

  litigation-related costs, which may be significant;

  adverse economic conditions in the U.S. and those foreign countries in which we operate, as well as our ability to respond to unanticipated

developments, such as the imposition of tariffs or trade restrictions;

  adverse budgetary conditions within the U.S. government, particularly the Department of Defense, which continue to influence spending

on current and anticipated programs into which we sell or anticipate to sell our products;

  costs related to compliance with increasing worldwide governance, quality, environmental, and other regulations;

  costs and consequences of disruption by third-parties of our global computer network and related resources; and

  the effects of events outside of our control, including public health emergencies, natural disasters, terrorist activities, political risks,

international conflicts, information security breaches, communication interruptions, and other force majeure.

As a result of these and other factors, we cannot assure you we will not experience significant fluctuations in future operating results on a
quarterly or annual basis. In addition, if our operating results do not meet the expectations of investors, the market price of our Common Stock may
decline.

Global economic uncertainty associated with the COVID-19 pandemic could materially and adversely affect our business and consolidated
operating results.

During 2020, global economic conditions varied by region, and were rapidly and significantly influenced by the COVID-19 pandemic. The
COVID-19 pandemic and the response of governments worldwide to contain its spread negatively influenced our financial and operational performance
for all four quarters of 2020, and future developments may have a potentially more substantial negative influence on our financial and operational
performance over an unknown period of time.

Our deliveries to and orders from North American industrial and defense electronics customers declined sharply at the onset of the pandemic,
during the first quarter of 2020, given reduced manufacturing activity and broad uncertainty. The second half of 2020 saw a recovery of North American
activity to pre-pandemic levels. Further growth continued through 2021.

Trading conditions in China (inclusive of Hong Kong, our largest international market), had deteriorated through 2019 due to macroeconomic and

trade-related uncertainties. At the beginning of 2020, trading conditions were significantly further affected by the COVID-19 pandemic, with much of
the country’s manufacturing disrupted for January and February 2020. By late March 2020, after aggressive measures to contain the coronavirus, the
Chinese government quickly implemented economic stimulus measures, and we experienced a rapid recovery of demand from China and Hong Kong.
This demand was sustained through the first part of 2021 before subsiding in late 2021. As addressed in our discussion herein of market characteristics,
exports to China and Hong Kong for 2021 totaled approximately $98,700,000, representing approximately 27.5% of total revenue for the year. We
believe this volume was primarily associated with the stimulus spending of the Chinese government, although we also believe an unquantifiable amount
of this volume may have been associated with accelerated purchasing by customers anticipating further deterioration of the trade relationship between
China and the U.S., which, if it were to occur, could substantially limit purchases by such customers. Our belief is based on input from our distribution
partners in China, as well as the mix of products exported over the past four years,

15

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

reflecting the transfer by our OEM customers for Advanced Products (and their contract manufacturers) of the majority of production programs from
China and Hong Kong to other countries in order to avoid inbound and outbound tariffs. Exports to China and Hong Kong peaked at approximately
$109,000,000 in 2018, but that figure included approximately $50,000,000 of exports of Advanced Products to OEM customers and their contract
manufacturers.

We anticipate demand in 2022 from China and Hong Kong will decline, based on information from our customers and distribution partners.
Should China’s economic stimulus policies change or if there is a further deterioration of trade relations between the U.S. and China, such demand may
further decline. However, we cannot predict if or when circumstances may change, nor can we predict the amount by which bookings or shipments may
change.

We have taken action to protect the health and safety of our workforce and to otherwise minimize the potential impact of the coronavirus on our

operations, the costs of which, to date, have not had a material effect on our financial performance. We expect to maintain the measures put in place until
we determine the COVID-19 pandemic is adequately contained for purposes of our business, and we may take further actions we consider to be in the
best interests of our employees, customers, business partners, and suppliers or in response to government mandate or requirement. Such further actions
may have a negative influence on our costs and productivity and, in turn, our financial and operational performance.

Our customers, business partners, and suppliers have been and may continue to be adversely affected by the COVID-19 pandemic, which also

may contribute to a negative influence on our future financial and operational performance.    

Global economic and political uncertainties, notably those associated with trade policy, could materially and adversely affect our business and
consolidated operating results.

For the years ended December 31, 2021, 2020, and 2019, revenues from sales outside the United States were 67.0%, 64.4%, and 53.7%,

respectively, of our total revenues. Net revenues from customers in China and Hong Kong, our largest international market, accounted for approximately
27.5% in 2021, approximately 31.4% in 2020, and approximately 22.1% in 2019, respectively, of total net revenues. We expect international sales,
notably in Asia, will continue to be a significant component of total sales, since many of the OEMs and ODMs we target as customers are domiciled
offshore, and such customers increasingly utilize offshore contract manufacturers, and rely upon those contract manufacturers to place orders directly
with us. We also expect international revenue from our distributors to continue to increase.

To date, we have not experienced material delays or reduced raw material availability as a result of trade disputes between the U.S. and China,

including the imposition in 2018 of import tariffs under the provisions of Section 301 of the Trade Act of 1974 (19 U.S.C. § 2411) (“Section 301
Tariffs”) on certain Chinese goods imported into the United States. However, the costs of Section 301 Tariffs have had a material impact on our
profitability. For the year ended December 31, 2021, Section 301 Tariffs totaled approximately $6,678,000, a decrease of 8% over the $7,259,000
incurred for 2020. For 2021, 2020 and 2019, Section 301 Tariffs totaled approximately 1.9%, 2.4% and 2.0%, respectively, of annual revenue,
representing a material reduction in our gross profit margin as a percentage of annual revenue.

We continue to evaluate alternative sources of raw materials, and in 2020 and 2021, we qualified non-Chinese vendors for certain high-volume

raw materials and components. We anticipate a reduction in Section 301 Tariffs we incur during 2022, given the ongoing transition to non-Chinese
vendors, but we are not able to estimate the amount of such reduction, if any. Similarly, we cannot predict if or when the U.S. government may reduce or
eliminate Section 301 Tariffs.

We also have filed “duty drawback” applications with U.S. Customs and Border Protection for the recovery of Section 301 Tariffs paid on raw

materials and components used to produce products we subsequently

16

 
Table of Contents

exported. We have recovered $676,000 through December 31, 2021, however, we are not able to estimate the amount or timing of any additional
recoveries, and there can be no assurance that there will be any additional recoveries.

In 2019, China implemented reciprocal inbound tariffs of up to 25% on products exported from the U.S., including all of our products. We do not
believe these tariffs, incurred by our Chinese and Hong Kong distributors, have had a material impact on the unit volume or dollar value of our exports
to China, which we attribute to the differentiated performance of our products in market segments in which we have an established presence. However,
we cannot predict the long-term influence of these tariffs on our competitive position in China, especially in light of the increased pressure by the
Chinese government on Chinese manufacturers to meet the “China 2025” mandate for targeted development of Chinese technology sectors. Under this
mandate, domestic technology vendors are explicitly favored over foreign vendors such as Vicor. We believe we experienced reduced demand in certain
segments (e.g., rail), notably in 2019, reflecting the significant role of state-owned enterprises in those segments. We regularly assess the competitive
position and profitability of certain product lines sold in China and Hong Kong, and may choose to reduce our product offerings if competitive
conditions and reduced profitability so warrant.

Uncertain macroeconomic conditions, extended trade disputes, and the relative strength of the U.S. Dollar may reduce end-demand for our
customers’ products and, in turn, their purchases of our products, thereby reducing our revenues and earnings. In addition, such adverse conditions may,
among other things, result in increased price competition for our products, notably in Brick Product categories, increased risk of excess and obsolete
inventories, increased risk in the collectability of our accounts receivable from our customers, increased risk in potential reserves for doubtful accounts
and write-offs of accounts receivable, and higher operating costs as a percentage of revenues.

Our operating results recently have been influenced by a limited number of customers, and our future results may be similarly influenced.

Since the introduction of our Advanced Products, the Company has derived the majority of its revenue from Advanced Products in any given year

from either one customer or a limited number of customers, whether through sales directly to the customer(s) or indirectly to the customers’ contract
manufacturers. This concentration of revenue is a reflection of the relatively early stage of adoption of the Advanced Products and the associated
technologies and power system architectures, and our targeting of market leading innovators as initial customers.

Our current sales and marketing efforts are focused primarily on accelerating the adoption of Advanced Products by a diversified customer base,

across a number of identified market segments. While we believe we have been successful to date in diversifying our Advanced Products customer base
beyond early adopters, we cannot assure you our strategy will be successful and further diversification of customers will be achieved.

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.

The power systems industry, and the electronics industry as a whole, can be subject to pronounced, lengthy business cycles and otherwise subject

to sudden and sharp changes in demand. Our success, in part, is dependent on our ability to forecast and procure inventories of components and
materials to match production schedules and customer delivery requirements. Many of our products require raw materials supplied by a limited number
of vendors and, in some instances, a single vendor. During certain periods, key components or materials required to build our products may become
unavailable in the timeframe required for us to meet our customers’ needs. Our inability to secure sufficient raw materials to manufacture products for
our customers has reduced, in the past, our revenue and profitability and could do so again. Over the course of the last year there have been
circumstances where supply disruptions, often associated with the global pandemic, have impacted our results.

17

 
Table of Contents

We may choose, and have chosen, to mitigate our inventory risks by increasing the levels of inventory for certain components and materials. Such

increased inventory levels may increase the potential risk for excess or obsolete inventories, should our forecasts fail to materialize or if there are
negative factors impacting our customers’ end markets, leading to order cancellation. If we identify excess inventory or determine certain inventory is
obsolete (i.e., unusable), we likely will record additional inventory reserves (i.e., expenses representing the write-off of the excess or obsolete
inventory), which could have an adverse effect on our gross margins and on our operating results.

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.

We depend on third-party vendors and subcontractors to supply components, assemblies, and services used to manufacture our products, some of

which are supplied by a single vendor. We have experienced shortages of certain semiconductor components and delays in service delivery, have
incurred additional and unexpected costs to address the shortages and delays, and have experienced our own delays in production and shipping.

If suppliers or subcontractors cannot provide their products or services on time or to our specifications, we may not be able to meet the demand for
our products and our delivery times may be negatively affected. In addition, we cannot directly control the quality of the products and services provided
by third parties. In order to expand revenue, we likely will need to identify and qualify new suppliers and subcontractors to supplant or replace existing
suppliers and subcontractors, which may be a time-consuming and expensive process. In addition, any qualification of new suppliers may require
customers of our products utilizing products and services from new suppliers and service providers to undergo a re-qualification process. Such
circumstances likely would lead to disruptions in our production, increased manufacturing costs, delays in shipping to our customers, and/or increases in
prices paid to third parties for products and services.

As previously disclosed, we rely on a third-party partner to provide certain manufacturing steps associated with a proprietary Advanced Products

packaging process. This process, developed with the third-party partner, involves complex electroplating, performed on equipment developed by the
third-party partner. An important, differentiating benefit of this proprietary process is that it does not generate problematic effluent, resulting in an
environmentally safe approach to electroplating, with minimal waste. We have entered into agreements with the third-party partner for production and
transfer of technologies and process know-how, including the purchase of the enabling equipment developed by the third-party partner.    

To date, we have successfully relied upon this third-party partner to perform these manufacturing steps, although we have experienced delivery
delays and higher costs associated with the third-party partner’s volume constraints. This experience has caused us to establish our own high-volume
capabilities in-house, modifying, in 2020, our construction plans to accommodate a dedicated, on-premises electroplating process facility. This project is
nearing completion, as discussed elsewhere. We expect to rely on our third-party partner for production requirements through the installation and
qualification for production of the enabling equipment in the addition to our Andover manufacturing facility. We may also rely on our third-party partner
in the future for surge capacity requirements.

If the third-party partner cannot deliver sufficient volumes to us, if we are unable to complete our facility expansion in a timely manner, or if we
are unable to effectively implement the new manufacturing processes, we may not be able to achieve the expected volumes or production capacity and,
as a result, may experience reduced manufacturing yields, delays in product deliveries, and/or increased expenses, any of which could negatively
influence our financial condition and results of operations.

Extended interruption of production at our manufacturing facility in Andover, Massachusetts, could materially reduce our revenue, increase our
costs, and, potentially, negatively impact our customers.

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.

18

 
Table of Contents

Substantial damage to our existing manufacturing facility due to fire, natural disaster, power loss, or other events, including disruptive events
associated with our ongoing expansion of the facility, could interrupt manufacturing, contributing to lengthy shipment delays that could have a negative
impact on customers and, in turn, our customer relationships. While we have never experienced any meaningful interruption of manufacturing in our
history, any prolonged inability to utilize all or a significant portion of our Andover facility could have a material adverse effect on our results of
operations.

An extended delay in completing our capacity expansion could have a material adverse effect on our results of operations and negatively impact
our ability to execute on our Advanced Products strategy.

We have been making and will continue to make capital investments for the expansion of manufacturing capacity for the production of Advanced
Products at our Andover facility. Based on our extended long-term volume forecast, we anticipate additional capacity will be required to meet expected
customer requirements. During the second quarter of 2020, we began construction of an approximately 90,000 square foot, two-story addition to our
existing plant, and that construction continues on a modified schedule, which accounts for a delay in completing construction from 2021 to 2022, and
reflects an expectation that production will begin later this year.

The addition to our facility includes installation of certain equipment and implementation of certain manufacturing steps associated with
Advanced Products manufacturing processes we currently outsource to a third-party partner, as described above. These manufacturing processes are
associated with a proprietary packaging approach requiring complex electroplating processes using environmentally safe technologies. Given our
volume expectations and the proprietary elements of these processes, we have chosen to accelerate the development of a captive capacity that we expect
will exceed the total capacity available from our third-party partner. Today, we own and operate, with our employees, certain equipment on premises at
our third-party partner and, as such, have established a level of operational competence we believe will enable us to successfully install and implement
these manufacturing processes internally. However, we may experience delays and incur additional costs during 2022 in implementing the
manufacturing processes, given the complexity of the installation and qualification of the equipment.

Once the facility expansion has been completed and all manufacturing equipment installed and qualified for volume production, we may not

achieve the anticipated production volumes and operating efficiencies. As we qualify equipment and bring production online, any delay in achieving
anticipated operating efficiencies associated with added capacity may cause manufacturing costs to be higher than expected for some period of time,
thereby potentially negatively influencing our operating and financial results.

Disruption of our information technology infrastructure could adversely affect our business.

We depend heavily on our computing and communications infrastructure to achieve our business objectives, particularly for our financial and

operational record keeping, our computer-integrated manufacturing processes controlling all aspects of our operations in our manufacturing facility in
Andover, Massachusetts, our public website, and our email communications. We also rely on trusted third parties to provide certain infrastructure
support services to us. If we or a third party service provider encounter a problem that impairs this infrastructure, the resulting disruption could impede
the accuracy and timeliness of our financial reporting processes, and our ability to record or process customer orders, manufacture, and ship in a timely
manner, or otherwise carry on business in the normal course. Our image and reputation also could be negatively affected by such circumstances.
Additionally, we could incur material liabilities associated with the harm such impairment and disruption of our infrastructure may have on third parties
including those associated with the unintentional release of confidential information and or sensitive data. While we carry business interruption
insurance to offset financial losses from such an interruption, and cyber-risk insurance to address potential liabilities from such circumstances, such
insurance may be insufficient to compensate us for the potentially significant costs or liabilities incurred. Any such events, if prolonged, could have a
material and adverse effect on our operating results and financial condition.

19

 
Table of Contents

On December 24, 2019, elements of our network were compromised by a form of malware referred to as “ransomware.” In close collaboration

with our service provider, we had restored computing and network functions to full operational status by the afternoon of December 27, 2019.
Subsequent analysis by management and the forensic specialists we retained allowed us to conclude the incident had no material impact on our
operations, financial condition and performance, or the integrity of our financial reporting systems. In response to the vulnerabilities identified, we have
substantially enhanced network and file security through expanded and improved system monitoring, network and file access procedures, user training,
and emergency response protocols. However, even with our expanded commitment to continuous improvement of the security of our information
technology infrastructure, we can offer no assurance that we will be successful in detecting or preventing network security incidents and associated
disruptions in the future.

Our systems are designed to protect us from network security incidents and associated disruptions. However, as evidenced by the ransomware

incident described above, we remain vulnerable to computer viruses and related software-based challenges to the integrity of our systems, unauthorized
or illegal break-ins, or malicious network hacking, equipment or software sabotage, acts of vandalism to our systems by third parties, and, in the
extreme, forms of cyber-terrorism. Our security measures or those of our third party service provider detected, but did not prevent, the network security
incident and the associated disruptions described above and may not detect or prevent such incidents and disruptions in the future.

As of December 31, 2021, we were compliant with the comprehensive requirements for the protection of controlled unclassified information
(“CUI”) as set forth in Special Publication 800-171 of the National Institute of Standards and Technology (“NIST”). The Company provides confidential
information to third party business partners and/or receives confidential information from third party business partners in certain circumstances, when
doing so is necessary to conduct business, particularly with departments of agencies of the U.S. Government. While we employ confidentiality
agreements to protect other sensitive information (i.e., information not considered CUI), our own security measures or those of our third party service
providers may not be sufficient to protect such information in the event the computing infrastructure of these third party business partners is
compromised. Security incidents involving our computing and communications infrastructure or that of a third party business partner or service provider
could result in the misappropriation or unauthorized release of confidential information belonging to us or to our employees, partners, customers or
suppliers, which could result in an interruption to our operations, result in a violation of privacy or other laws, expose us to a risk of litigation, or
damage our reputation, any of which could have a material and adverse effect on our operating results and financial condition. Our network segmented
NIST 800-171 environment was not impacted by the December 2019 ransomware incident, but there can be no assurance that it will not be impacted by
similar incidents in the future, which could have a material and adverse effect on our operating results and financial condition for the reasons described
above.

We may face legal claims and litigation from product warranty or other claims that could be costly to resolve.

We have in the past and may in the future encounter legal action from customers, vendors, or others concerning product warranty or other claims.

We generally offer a two-year warranty from the date title passes from us for all of our standard products. Effective January 1, 2017, we extended the
warranty period to three years for a range of H Grade, M Grade and MI Family DC-DC legacy products sold after that date. In a limited number of
circumstances, we have entered into supply contracts with certain high-volume customers calling for extended warranty terms. With our distribution
partners, we also enter into contracts providing for our product warranties to transfer to the end customer upon final sale of our product(s) by the
distributor.

We invest significant resources in the testing of our products; however, if any of our products contain defects, we may be required to incur
additional development and remediation costs, pursuant to our warranty policies. These issues may divert our technical and other resources from other
product development efforts and could result in claims against us by our customers or others, including liability for costs associated with product

20

 
Table of Contents

returns, which may adversely influence our operating results. If any of our products contain defects, or have reliability, quality, or compatibility
problems, the Company’s reputation may be damaged, which could make it more difficult for us to sell our products to existing and prospective
customers and could adversely affect our operating results. We are currently party to a limited number of supply agreements with certain customers
contractually committing us to warranty and indemnification requirements exceeding those to which we have been exposed in the past. While we
maintain insurance coverage for such exposure, we could incur significant financial cost beyond the limits of such coverage, as well as operational
disruption and damage to our competitive position and image if faced with a significant product warranty or other claim.

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 success depends on our ability to retain the services of our executive officers. The loss of one or more members of senior management could

materially adversely influence our business and financial results. In particular, we are dependent on the services of Dr. Vinciarelli, our founder,
Chairman of the Board, Chief Executive Officer, and President. The loss of the services of Dr. Vinciarelli could have a material adverse effect on our
development of new products and on our results of operations. In addition, our research and development and marketing and sales activities depend on
highly skilled engineers and other personnel with technical skills, who are in high demand and are difficult to replace. Our continued operations and
growth depend on our ability to attract and retain skilled and experienced personnel in a very competitive employment market. If we are unable to attract
and retain such employees, our ability to successfully implement our business strategy may be harmed. The labor market for skilled and unskilled
workers has been very tight over the past year, and at times we have experienced longer than normal times in recruiting necessary resources, and have
had to increase compensation to attract and retain employees.

Competitive Risks

We compete with many companies possessing far greater resources.

Some of our competitors have far greater financial, manufacturing, technical, and sales and marketing resources than we possess or have access to.

Our Brick Products compete with those products offered by domestic and foreign manufacturers of integrated power supplies and related power
conversion components. With our Advanced Product lines, we compete with global IDMs and fabless developers of semiconductor-based power
management modules and power management ICs. These competitors have far larger organizations and broader semiconductor-based product lines.
Competition is generally based on product performance, design flexibility (i.e., ease of use), product price, and product availability, but with the relative
importance of these factors varying among products, markets, and customers.

Existing or new competitors may develop products or technologies that more effectively address the demands of our customers and markets with

enhanced performance, features and functionality, or lower cost. Larger competitors frequently seek to maintain market share and protect customer
relationships through heavily-discounted pricing, which we may not be able to match. If we fail to develop and commercialize leading-edge
technologies and products that are cost effective and maintain high standards of quality, and introduce them to the market on a timely basis, our
competitive position and results of operations could be materially adversely affected.

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.

The power system industry and the industries in which many of our customers operate are characterized by intense competition, rapid

technological change, quickened product obsolescence, and price erosion for mature

21

 
Table of Contents

products, each of which could have an adverse effect on our results of operations. We are following a strategy based on the development of
differentiated Advanced Products addressing what we believe to be the long-term limitations of traditional power architectures, while at the same time
sustaining sales and profitability of our well-established Brick Products. The development of new, innovative products is often a complex, time-
consuming, and costly process involving significant investment in research and development, with no assurance of return on investment. Although we
have introduced many Advanced Products over recent years, there can be no assurance we will be able to continue to develop and introduce new and
improved products and power system concepts in a timely or efficient manner. Similarly, there can be no assurance recently introduced or to be
developed products will achieve customer acceptance.

Our future success depends substantially upon further customer acceptance of our innovative Advanced Products including our Power-on-Package

concept for the computing market and Advanced Products supporting the electrification of automobiles. As we have been in the early stages of market
penetration for these and other Advanced Products, we have experienced lengthy periods during which we have focused our product development efforts
on the specific requirements of a limited number of large customers, followed by further periods of delay before meaningful purchase orders are
received. These lengthy development and sales cycle times increase the possibility a customer may decide to cancel or change product plans, which
could reduce or eliminate our sales to that customer. As a result, we may incur significant product development expenses, as well as significant sales and
marketing expenses, before we generate the related revenues for these products. Furthermore, we may never generate the anticipated revenues from a
product after incurring such expenses if our customer cancels or changes its product plans.

In 2021, we continued our expansion of a dedicated sales effort to penetrate the automotive market with our Advanced Products, notably in the
electrification of passenger automobiles. Our Power Component Design Methodology provides conversion solutions for 800V, 400V, and 48V within
advanced electric vehicles. The automotive market is dominated by relatively few global OEMs and “tiers” of well-established suppliers. Penetrating
this market will be challenging and we may not be successful in doing so.

We continue to shift our go-to-market strategy to focus on larger opportunities with global OEMs, ODMs, and contract manufacturers. Our growth
is therefore dependent on: the pace at which these OEMs and ODMs develop their own new products; the acceptance of our Advanced Products by these
OEMs and ODMs; and the success of the customers’ products incorporating our Advanced Products. If we fail to anticipate changes in our customers’
businesses and their changing product needs or do not successfully identify and enter new markets, our results of operations and financial position could
be negatively impacted.

We cannot offer any assurance the markets we currently serve will grow in the future, our Advanced Products or Brick Products will meet

respective market requirements, or we can maintain adequate gross margins or operating profits in these markets.

Intellectual Property Risks

We may be unable to adequately protect our proprietary rights, which may limit our ability to compete effectively.

We operate in an industry in which the ability to compete depends on the development or acquisition of proprietary technologies that must be
protected to preserve the exclusive use of such technologies. We devote substantial resources to establish and protect our patents and proprietary rights,
and we rely on patent and intellectual property law to protect such rights. This protection, however, may not prevent competitors from independently
developing products similar or superior to our products. We may be unable to protect or enforce current patents, may rely on unpatented technology that
competitors could restrict or replicate, or may be unable to acquire patents in the future, all of which may have a material adverse effect on our
competitive position. In addition, the intellectual property laws of foreign countries may not protect our rights to the same extent as those

22

 
Table of Contents

of the United States. We have been defending and may need to continue to defend or challenge patents. We have incurred and expect to incur significant
financial costs in the defense of our patented technologies and have devoted and expect to devote significant resources to these efforts which, if
unsuccessful, may have a material adverse effect on our operating results and financial position.

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.

The power supply industry is characterized by vigorous protection and pursuit of intellectual property rights. We have in the past and may in the

future receive communications from third parties asserting that our products or manufacturing processes infringe on a third party’s patent or other
intellectual property rights. Such assertions, if publicly disclosed, have in the past and may in the future inhibit the willingness of potential customers to
purchase certain of our products. In the event a third party makes a valid intellectual property claim against us and a license is not available to us on
commercially reasonable terms, or at all, we could be forced to either redesign or stop production of products incorporating that technology, and our
operating results could be materially and adversely affected. In addition, litigation may be necessary to defend us against claims of infringement, and
this litigation could be costly, extend over a lengthy period of time, and divert the attention of key personnel. An adverse outcome in these types of
matters could have a material adverse impact on our operating results and financial condition.

Please see Note 15 — Commitments and Contingencies, to the Consolidated Financial Statements for information regarding current litigation

related to our intellectual property.

Any expenses or liability resulting from the outcome of litigation could adversely influence our operating results and financial condition.

From time to time, we may be subject to claims or litigation, including intellectual property litigation as described elsewhere in this Annual Report

on Form 10-K. Any such claims or litigation may be time-consuming and costly, divert management resources, require us to change our products, or
have other adverse effects on our business. Any of the foregoing could have a material adverse effect on our operating results and could require us to
pay significant monetary damages.

The outcomes of legal proceedings and claims brought against us are subject to significant uncertainty. An estimated loss from a loss contingency

such as a legal proceeding or claim is accrued by a charge to income if it is considered probable an asset has been impaired or a liability has been
incurred and the amount of the loss can be reasonably estimated. Disclosure of a contingency is required if there is at least a reasonable possibility that a
loss has been incurred. In determining whether a loss should be accrued, we evaluate, among other factors, the degree of probability of an unfavorable
outcome and the ability to make a reasonable estimate of the amount of loss. Changes in these factors could materially impact our financial statements.
As of December 31, 2021, our evaluation led us to conclude no accrual of a loss contingency was warranted.

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.

An effective internal control environment is necessary for us to produce reliable financial reports and is an important part of our effort to prevent
financial fraud. Section 404 of the Sarbanes-Oxley Act of 2002 (“SOX”) requires our management to report on, and our independent registered public
accounting firm to attest to, the effectiveness of our internal control over financial reporting.

23

 
Table of Contents

We have an ongoing program to perform the system and process evaluation and testing necessary to comply with the requirements of SOX and to

continuously improve and, when necessary, remediate internal controls over financial reporting.

While management evaluates the effectiveness of our internal controls on a regular basis, these controls may not always be effective. There are
inherent limitations on the effectiveness of internal controls, including collusion, management override, and failure in human judgment. In addition,
control procedures are designed to reduce rather than eliminate business risks. In the event our Chief Executive Officer or Chief Financial Officer, our
certifying officers under SOX, or our independent registered public accounting firm determines our internal controls over financial reporting are not
effective as defined under Section 404, we may be unable to produce reliable financial reports or prevent fraud, which could materially harm our
business. In addition, we may be subject to sanctions or investigation by government authorities or self-regulatory organizations, such as the SEC, the
Financial Industry Regulatory Authority, or The NASDAQ Stock Market LLC. Any such actions could affect investor perceptions of the Company and
result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements, which could cause the
market price of our Common Stock to decline or limit our access to capital.

Regulations related to conflict minerals could adversely impact our business.

The Dodd-Frank Wall Street Reform and Consumer Protection Act contains provisions to improve transparency and accountability concerning the

supply of certain minerals, known as conflict minerals (including gold, tantalum, tin, and tungsten, and their related ores), originating from the
Democratic Republic of Congo (“DRC”) and adjoining countries. As a result, in August 2012 the SEC released final rules for annual disclosure and
reporting for those companies who use conflict minerals mined from the DRC and adjoining countries in their products. We began to implement
processes within our supply chain to comply with these rules beginning in 2012, filed our initial Form SD in May 2014, and have filed Form SD
annually since then. There have been and will continue to be costs associated with complying with these disclosure requirements, including due
diligence to determine the sources of conflict minerals used in our products and other potential changes to products, processes, or sources of supply as a
consequence of such verification activities. The implementation of these rules could adversely affect the sourcing, supply, and pricing of materials used
in our products. As there may be only a limited number of suppliers offering “conflict free” conflict minerals, we cannot be certain we will be able to
obtain necessary conflict minerals from such suppliers in sufficient quantities or at competitive prices. Also, we may face reputational challenges if we
determine that certain of our products contain minerals not determined to be conflict free or if we are unable to sufficiently verify the origins for all
conflict minerals used in our products through the procedures we may implement.

Risks Related to Share Value

The price of our Common Stock has been volatile and may fluctuate in the future.

Because of the factors set forth above and below, among others, the trading price of our Common Stock has fluctuated and may continue to

fluctuate significantly:

•

•

•

•

•

  volatility of the financial markets, notably the equity markets in the U.S.;

  uncertainty regarding the prospects of domestic and foreign economies, including the impact of volatile currency exchange rates;

  uncertainty regarding domestic and international political conditions, including tax, trade, and tariff policies;

  actual or anticipated fluctuations in our operating performance or that of our competitors;

  the performance and prospects of our major customers, including their adoption of technologies or standards other than those in which we

specialize;

24

 
 
 
 
 
 
 
 
 
 
 
Table of Contents

•

•

•

•

•

  announcements by us or our competitors of significant new products, technical innovations, or litigation;

  investor perception of the Company and the industry in which we operate;

  the liquidity of the market for our Common Stock, reflecting a relatively low trading float and relatively low average trading volumes;

  the uncertainty of the declaration and payment of future cash dividends on our Common Stock; and

  the concentration of ownership of our Common Stock by Dr. Vinciarelli, our Chairman of the Board, Chief Executive Officer, and

President.

In the past, we have declared and paid cash dividends on our Common Stock. The payment of dividends is based on the periodic determination by

our Board of Directors that we have adequate capital to fund anticipated operating requirements and that excess cash is available for distribution to
stockholders via a dividend. We have no formal policy regarding dividends and, as such, investors cannot make assumptions regarding the possibility of
future dividend payments nor the amounts and timing thereof. As of December 31, 2021, we have no plans to declare or pay a cash dividend.

The ownership of our Common Stock is concentrated between Dr. Vinciarelli and a limited number of institutional investors. As of December 31,

2021, Dr. Vinciarelli was the beneficial owner of 9,592,017 shares of our Common Stock, plus 273,394 shares which Dr. Vinciarelli has the right to
acquire upon exercise of options to purchase Common Stock within 60 days of December 31, 2021. He also holds 11,023,648 shares of our unregistered
Class B Common Stock (which may only be sold or transferred after required conversion, on a one-for-one basis, into registered shares of Common
Stock), which together with his ownership of Common Stock, represents 48.1% of our total issued and outstanding shares of capital stock. Accordingly,
the market float for our Common Stock and average daily trading volumes are relatively small, which may negatively impact investors’ ability to buy or
sell shares of our Common Stock in a timely manner.

Dr. Vinciarelli owns 93.8% of the issued and outstanding shares of our Class B Common Stock, which possess 10 votes per share. Dr. Estia J.

Eichten, a member of our Board of Directors, owns the majority of the balance of the Class B Common Stock issued and outstanding. As such,
Dr. Vinciarelli, controlling in aggregate 80.0% of our outstanding voting securities, has effective control of our governance.

PROPERTIES

Our corporate headquarters building in Andover, Massachusetts, which we own, provides approximately 90,000 square feet of office space for our

sales, marketing, engineering, and administrative personnel. We also own a building of approximately 320,000 square feet in Andover, Massachusetts,
including the expansion discussed below, which houses all Massachusetts manufacturing activities.

Current capital investments are focused on the expansion of manufacturing capacity for the production of Advanced Products at our Andover

facility. Based on our long-term forecast of production levels, we anticipate substantial additional capacity will be required to meet expected
requirements beyond 2023. During 2020, we began construction of a two-story addition to our Andover manufacturing facility that is intended to expand
the Advanced Products production area by approximately 90,000 square feet. Completion of the construction and production have been delayed from
2021 to 2022. We have received an occupancy permit, though, for the addition and therefore equipment installation is underway. We also are proceeding
with the evaluation of alternative projects for the addition of another, larger manufacturing facility to be focused on Advanced Products for automotive
applications, should we anticipate the need based on our forecasts for capacity beyond 2023.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

A discussion regarding our results of operations for the year ended December 31, 2020, compared to the year ended December 31, 2019, was included
in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, on pages 35-37 under Part II, Item 7, “Management’s
Discussion and Analysis of Financial Condition and Results of Operations”, which was filed with the SEC on March 1, 2021.

We design, develop, manufacture, and market modular power components and power systems for converting electrical power for use in

electrically-powered devices. Our competitive position is supported by innovations in product design and achievements in product performance, largely
enabled by our focus on the research and development of advanced technologies and processes, often implemented in proprietary semiconductor
circuitry, materials, and packaging. Many of our products incorporate patented or proprietary implementations of high-frequency switching topologies
enabling power system solutions that are more efficient and much smaller than conventional alternatives. Our strategy emphasizes demonstrable product
differentiation and a value proposition based on competitively superior solution performance, advantageous design flexibility, and a compelling total
cost of ownership. While we offer a wide range of alternating current (“AC”) and direct current (“DC”) power conversion products, we consider our
core competencies to be associated with 48V DC distribution, which offers numerous inherent cost and performance advantages over lower distribution
voltages. However, we also offer products addressing other DC voltage standards (e.g., 380V for power distribution in data centers, 110V for rail
applications, 28V for military and avionics applications, and 24V for industrial automation).

Based on design, performance, and form factor considerations, as well as the range of evolving applications for which our products are

appropriate, we categorize our product portfolios as either “Advanced Products” or “Brick Products.” The Advanced Products category consists of our
more recently introduced products, which are largely used to implement our proprietary Factorized Power Architecture™ (“FPA”), an innovative power
distribution architecture enabling flexible, rapid power system design using individual components optimized to perform a specific conversion function.

The Brick Products category largely consists of our broad and well-established families of integrated power converters, incorporating multiple
conversion stages, used in conventional power systems architectures. Given the growth profiles of the markets we serve with our Advanced Products
line and our Brick Products line, our strategy involves a transition in organizational focus, emphasizing investment in our Advanced Products line and
targeting high growth market segments with a low-mix, high-volume operational model, while maintaining a profitable business in the mature market
segments we serve with our Brick Products line with a high-mix, low-volume operational model.

The applications in which our Advanced Products and Brick Products are used are typically in the higher-performance, higher-power segments of

the market segments we serve. With our Advanced Products, we generally serve large Original Equipment Manufacturers (“OEMs”), Original Design
Manufacturers (“ODMs”), and their contract manufacturers, with sales currently concentrated in the data center and hyperscaler segments of enterprise
computing, in which our products are used for voltage distribution on server motherboards, in server racks, and across datacenter infrastructure. We have
established a leadership position in the emerging market segment for powering high-performance processors used for acceleration of applications
associated with artificial intelligence (“AI”). Our customers in the AI market segment include the leading innovators in processor and accelerator design,
as well as early adopters in cloud computing and high performance computing. We also target applications in aerospace and aviation, defense
electronics, industrial automation, instrumentation, test equipment, solid state lighting, telecommunications and networking infrastructure, and vehicles
(notably in the autonomous driving, electric vehicle, and hybrid vehicle niches of the vehicle segment). With our Brick Products, we generally serve a
fragmented base of large and small customers, concentrated in aerospace and

29

 
Table of Contents

defense electronics, industrial automation, industrial equipment, instrumentation and test equipment, and transportation (notably in rail and heavy
equipment applications). With our strategic emphasis on larger, high-volume customers, we expect to experience over time a greater concentration of
sales among relatively fewer customers.

Our quarterly consolidated operating results can be difficult to forecast and have been subject to significant fluctuations. We plan our production

and inventory levels based on management’s estimates of customer demand, customer forecasts, and other information sources. Customer forecasts,
particularly those of OEM, ODM, and contract manufacturing customers to which we supply Advanced Products in high volumes, are subject to
scheduling changes on short notice, contributing to operating inefficiencies and excess costs. In addition, external factors such as supply chain
uncertainties, which are often associated with the cyclicality of the electronics industry, regional macroeconomic and trade-related circumstances, and
force majeure events (most recently evidenced by the COVID-19 pandemic), have caused our operating results to vary meaningfully. Our quarterly
gross margin as a percentage of net revenues may vary, depending on production volumes, average selling prices, average unit costs, the mix of products
sold during that quarter, and the level of importation of raw materials subject to tariffs. Our quarterly operating margin as a percentage of net revenues
also may vary with changes in revenue and product level profitability, but our operating costs are largely associated with compensation and related
employee costs, which are not subject to sudden or significant changes.

Ongoing / Potential Impacts of the COVID-19 Pandemic on the Company

As of the date of this report, the number of Company employees diagnosed with COVID-19 and the corresponding absenteeism due to COVID-19
are negligible. We did experience higher rates of absenteeism in January 2022, as experienced in many parts of the country during that period. While the
productivity of our factory is not currently impacted by COVID-19, productivity may be reduced if quarantine rates increase or if the number of
employees diagnosed with COVID-19 requires further implementation of restrictive health and safety measures, including factory closure. We continue
to operate with three shifts in our factory, and, with very few exceptions, our engineering, sales, and administrative personnel are working from the
Company’s offices.

We are closely monitoring the operating performance and financial health of our customers, business partners, and suppliers, but an extended

period of operational constraints brought about by the pandemic could cause financial hardship within our customer base and supply chain. Such
hardship may continue to disrupt customer demand and limit our customers’ ability to meet their obligations to us. Similarly, such hardship within our
supply chain could continue to restrict our access to raw materials or services. Additionally, restrictions or disruptions of transportation, such as reduced
availability of cargo transport by ship or air, could result in higher costs and inbound and outbound delays. We have taken steps to address certain supply
chain risks, and we believe our actions have mitigated those risks to date; however, there are no assurances that those steps will continue to mitigate
risks in 2022 and beyond.

Although there is uncertainty regarding the extent to which the pandemic will continue to impact our operational and financial results in the
future, the Company’s high level of liquidity, flexible operational model, existing raw material inventories, and increased use of second sources for
critical manufacturing inputs together support management’s belief the Company will be able to effectively conduct business until the pandemic passes.

We are monitoring the rapidly changing circumstances, and may take additional actions to address COVID-19 risks as they evolve. Because much

of the potential negative impact of the pandemic is associated with risks outside of our control, we cannot estimate the extent of such impact on our
financial or operational performance, or when such impact might occur.

2021 Financial Highlights

•

  Net revenues increased 21.2% to $359,364,000 for 2021, from $296,576,000 for 2020. The increase was primarily in sales of Advanced

Products, due to an increase in new orders for the year ended

30

 
 
 
Table of Contents

December 31, 2021, compared to the year ended December 31, 2020. Net revenues for Brick Products for 2021 decreased slightly
compared to 2020.    The increase in orders of Advanced Products largely reflected our customers’ response to the 20% to 30% increase in
lead-times, as well as growth in our data center and high performance computing business for Advanced Products.

  Export sales, as a percentage of total revenues, represented approximately 67.0% in 2021 and 64.4% in 2020.

  Gross margin increased to $178,200,000 for 2021, from $131,447,000 for 2020. Gross margin, as a percentage of net revenues increased to
49.6% for 2021 from 44.3% for 2020. The increase in gross margin dollars and gross margin percentage was primarily due to the increase
in net revenues, an improved mix of higher-margin products shipped, process yield improvements and lower tariff charges.

  Backlog, representing the total of orders for products received for which shipment is scheduled within the next 12 months, was

approximately $345,594,000 at the end of 2021, as compared to $147,550,000 at the end of 2020, due to the significant increase in orders
in 2021 compared to 2020.

  Operating expenses for 2021 increased $8,519,000, or 7.5%, to $122,598,000 from $114,079,000 for 2020, due to increases in selling,
general, and administrative expenses of $6,321,000 and research and development expenses of $2,198,000. Compensation and related
personnel costs closely track headcount and annual merit-based increases in salary and wages, which did increase in 2021 compared to
2020 for both selling, general, and administrative and research and development expenses. However, certain other expenses, such as
prototyping costs in research and development, or advertising and promotion costs associated with sales initiatives, can vary meaningfully
period to period.

  We reported net income for 2021 of $56,625,000, or $1.26 per diluted share, compared to net income of $17,910,000, or $0.41 per diluted

share, for 2020.

  In 2021, as a result of activities associated with our construction and capacity expansion, depreciation and amortization totaled
$11,705,000, and capital expenditures were $47,761,000, compared to $11,056,000 and $28,653,000, respectively, for 2020.

  Inventories increased by approximately $10,053,000, or 17.6%, to $67,322,000 at the end of 2021, as compared to $57,269,000 at the end

of 2020, primarily due to vendor component supply issues and limitations with our factory capacity, both of which contributed to
production delays. We expect these issues will continue to negatively impact production in 2022.

Management’s Discussion and Analysis of Financial Condition and Results of Operations is based upon our Consolidated Financial Statements,
which have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The preparation of these
financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses,
and

31

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
 
  
 
 
  
  
  
  
  
 
 
 
Table of Contents

related disclosures of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and assumptions, and our associated judgments,
including those related to inventories, income taxes, contingencies, and litigation. We base our estimates, assumptions, and judgments on historical
experience, knowledge of current conditions, and on various other factors we believe to be reasonable under the circumstances, the results of which
form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results
may differ from these estimates under different assumptions or conditions. We also have other policies we consider key accounting policies (See Note 2
to the Consolidated Financial Statements – Significant Accounting Policies –Recently Adopted Accounting Standards). However, the application of these
other policies does not require us to make significant estimates and assumptions difficult to support quantitatively.

Inventories

We employ a variety of methodologies to evaluate inventory that is estimated to be excess, obsolete or unmarketable, in order to write down that
inventory to net realizable value. Our estimation process for assessing net realizable value is based upon forecasted future usage which we derive based
on backlog, historical consumption, and expected market conditions. For both Brick and Advanced product lines, the methodology used compares
on-hand quantities to forecasted usage and historical consumption, such that amounts of inventory on hand in excess of management’s estimate of
expected future utility, are fully reserved. While we have used our best efforts and believe we have used the best available information to estimate future
demand, due to uncertainty in the economy and our business and the inherent difficulty in forecasting future usage, it is possible actual demand for our
products will differ from our estimates. If actual future demand or market conditions are less favorable than those projected by management, additional
inventory reserves for existing inventories may need to be recorded in future periods.

Evaluation of the Realizability of Deferred Tax Assets

Significant management judgment is required in determining whether deferred tax assets will be realized in full or in part. We assess the need for a
valuation allowance on a quarterly basis. We record a valuation allowance to reduce our deferred tax assets to the amount we believe is more likely than
not to be realized. In assessing the need for a valuation allowance, we consider all positive and negative evidence, including scheduled reversals of
deferred tax liabilities, projected future taxable income, tax planning strategies, and past financial performance. Despite recent positive operating results
as a result of increases in bookings, the Company is in a cumulative loss position as of December 31, 2021, primarily due to tax deductions on 2020 and
2021 exercises of stock-based compensation. The Company faces uncertainties in forecasting its operating results due to vendor supply and factory
capacity constraints, certain process issues with the production of Advanced Products and the unpredictability in certain markets. This operating
uncertainty also makes it difficult to predict the availability and utilization of tax benefits over the next several years. As a result, management has
concluded, at this time, is more likely than not the Company’s net domestic deferred tax assets will not be realized, and a full valuation allowance
against all net domestic deferred tax assets is still warranted as of December 31, 2021. The valuation allowance against these deferred tax assets may
require adjustment in the future based on changes in the mix of temporary differences, changes in tax laws, and operating performance. If the positive
operating results and increases in bookings continue, and the Company’s concerns about industry uncertainty and world events, supply and capacity
constraints, and process issues with the production of Advanced Products are resolved, and the amount of tax benefits the Company is able to utilize to
the point that the Company believes future taxable income can be more reliably forecasted, the Company may release all or a portion of the valuation
allowance in the near-term. Certain state tax credits, though, will likely never be released by the valuation allowance. If and when the Company
determines the valuation allowance should be released (i.e., reduced), the adjustment would result in a tax benefit reported in that period’s Consolidated
Statements of Operations, the effect of which would be an increase in reported net income.

The amount of any such tax benefit associated with release of our valuation allowance in a particular quarter may be material.

New Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) that we adopt as of the
specified effective date. Unless otherwise discussed, we believe the impact of recently issued accounting standards will not have a material impact on
our future financial condition and results of operations. See Note 2 – Significant Accounting Policies – Impact of recently issued accounting standards,
to the Consolidated Financial Statements for a description of recently issued and adopted accounting pronouncements, including the dates of adoption
and expected impact on our financial position and results of operations.

Other new pronouncements issued but not effective until after December 31, 2021 are not expected to have a material impact on our consolidated

financial statements.

Year ended December 31, 2021 compared to Year ended December 31, 2020

Consolidated net revenues for 2021 were $359,364,000, an increase of $62,788,000, or 21.2%, as compared to $296,576,000 for 2020.

Net revenues, by product line, for the years ended December 31 were as follows (dollars in thousands):

The increase in net revenues for Advanced Products was primarily the result of growth in the data center and high performance computing
business, in the United States and Asia Pacific markets. The decrease in net revenues for Brick Products was primarily due to a decrease in net revenues
from customers in the United States and Asia Pacific markets, partially offset by increases from customers in Europe. The increase in net revenues for
Advanced Products was also the result of increases in new orders for Advanced Products for the year ended December 31, 2021 compared to the year
ended December 31, 2020. The increase in orders largely reflected our customers’ response to the 20% to 30% increase in lead-times and growth in our
data center and high performance computing business for Advanced Products.

Gross margin for 2021 increased $46,753,000, or 35.6%, to $178,200,000 from $131,447,000 in 2020. Gross margin as a percentage of net
revenues increased to 49.6% in 2021 from 44.3% in 2020. The increase in gross margin dollars and gross margin percentage was primarily due to the
increase in net revenues, an improved mix of higher-margin products shipped, process yield improvements and lower tariff charges.

Selling, general, and administrative expenses were $69,484,000 for 2021, an increase of $6,321,000, or 10.0%, as compared to $63,163,000 for
2020. As a percentage of net revenues, selling, general, and administrative expenses decreased to 19.3% in 2021 from 21.3% in 2020, primarily due to
the increase in net revenues.

Interest income increased due to an increase in interest bearing investments in 2021 compared to 2020, due to the investment of the net proceeds

of approximately $109.7 million from our underwritten public offering of our Common Stock completed in June 2020. Our exposure to market risk
fluctuations in foreign currency exchange rates relates to the operations of VJCL, for which the functional currency is the Japanese Yen, and all other
subsidiaries in Europe and Asia, for which the functional currency is the U.S. Dollar. These subsidiaries in Europe and Asia experienced more
unfavorable foreign currency exchange rate fluctuations in 2021 compared to 2020.

Income before income taxes was $56,805,000 in 2021, as compared to $18,461,000 in 2020.

The provision for income taxes and the effective income tax rate for the years ended December 31 were as follows (dollars in thousands):

The effective tax rates were lower than the statutory tax rates for the year ended December 31, 2021 and 2020 primarily due to the Company’s full
valuation allowance position against domestic deferred tax assets and for excess tax benefits related to stock based compensation during both years. The
provision for income taxes for the years ended December 31, 2021 and 2020 included estimated federal, state and foreign income taxes in jurisdictions
in which the Company does not have sufficient tax attributes to fully offset taxable income.

See Note 14 to the Consolidated Financial Statements for disclosure regarding our current assessment of the valuation allowance against all

domestic deferred tax assets, and the possible release (i.e., reduction) of the allowance in the future.

At December 31, 2021, we had $182,418,000 in cash and cash equivalents and $45,215,000 of highly liquid short-term investments. The ratio of

current assets to current liabilities was 7.3:1 at December 31, 2021, as compared to 7.8:1 at December 31, 2020. Net working capital increased
$31,248,000 to $307,667,000 at December 31, 2021 from $276,419,000 at December 31, 2020.

The primary working capital changes were due to the following (in thousands):

Cash and cash equivalents
Short-term investments
Accounts receivable
Inventories
Other current assets
Accounts payable
Accrued compensation and benefits
Accrued expenses
Sales allowances
Short-term lease liabilities
Income taxes payable
Short-term deferred revenue and customer prepayments

The primary sources of cash for the year ended December 31, 2021 were $75,000,000 of cash from the sale or maturities of short-term

investments, $54,444,000 of cash generated from operations, and $10,243,000 of cash received in connection with the exercise of options to purchase
our Common Stock awarded under our stock option plans and the issuance of Common Stock under our 2017 Employee Stock Purchase Plan. The
primary uses of cash during the year ended December 31, 2021 were $70,900,000 for the purchases of short-term investments and $47,761,000 for the
purchase of property and equipment.

In November 2000, our Board of Directors authorized the repurchase of up to $30,000,000 of Common Stock (the “November 2000 Plan”). The

November 2000 Plan authorizes us to make such repurchases from time to time in the open market or through privately negotiated transactions. The
timing of such repurchases and the number of shares purchased in each transaction are at the discretion of management based on its view of economic
and financial market conditions. We did not repurchase shares of Common Stock under the November 2000 Plan during the year ended December 31,
2021. As of December 31, 2021, we had approximately $8,541,000 remaining for share purchases under the November 2000 Plan.

As of December 31, 2021, we had a total of approximately $32,949,000 of capital expenditure commitments, principally for manufacturing and

production equipment, which we intend to fund with existing cash, and approximately $4,803,000 of capital expenditure items which had been received
and included in Property, plant and equipment in the accompanying Consolidated Balance Sheets, but not yet paid for. As of December 31, 2021 we
have approximately $36,600,000 of remaining capital expenditures expected to be incurred through the first half of 2022 associated with the
construction of a 90,000 sq. ft. addition to the Company’s existing manufacturing facility and the installation of new production equipment. Of this
expected amount, which is primarily for the new production equipment, approximately $24,000,000 has been approved and is included in the aggregate
total of $32,949,000 of capital expenditure commitments above. The remaining amount of approximately $12,600,000 is expected to be approved in
2022. Our primary needs for liquidity are for

making continuing investments in manufacturing and production equipment and for funding the construction of the additional manufacturing space
adjoining our existing Andover manufacturing facility (as described above), including architectural and construction costs. We believe cash generated
from operations together with our available cash and cash equivalents and short-term investments will be sufficient to fund planned operational needs,
capital equipment purchases, and the planned construction, for the foreseeable future.

We do not consider the impact of inflation and changing prices on our business activities or fluctuations in the exchange rates for foreign currency

transactions to have been significant during the last three fiscal years.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to a variety of market risks, including changes in interest rates affecting the return on our cash and cash equivalents, short-term

investments and fluctuations in foreign currency exchange rates. As our cash and cash equivalents and short-term investments consist principally of cash
accounts, money market securities and U.S. Treasury securities, which are short-term in nature, we believe our exposure to market risk on interest rate
fluctuations for these investments is not significant. As of December 31, 2021, our long-term investment portfolio, recorded on our Consolidated
Balance Sheet as “Long-term investment, net”, consisted of a single auction rate security with a par value of $3,000,000, purchased through and held in
custody by a broker-dealer affiliate of Bank of America, N.A., that has experienced failed auctions (the “Failed Auction Security”) since February 2008.
While the Failed Auction Security is Aaa/AA+ rated by major credit rating agencies, collateralized by student loans and guaranteed by the U.S.
Department of Education under the Federal Family Education Loan Program, continued failure to sell at its periodic auction dates (i.e., reset dates) could
negatively impact the carrying value of the investment, in turn leading to impairment charges in future periods. Periodic changes in the fair value of the
Failed Auction Security attributable to credit loss (i.e., risk of the issuer’s default) are recorded through earnings as a component of “Other income
(expense), net”, with the remainder of any periodic change in fair value not related to credit loss (i.e., temporary “mark-to-market” carrying value
adjustments) recorded in “Accumulated other comprehensive income (loss)”, a component of Vicor Corporation Stockholders’ Equity. Should we
conclude a decline in the fair value of the Failed Auction Security is other than temporary, such losses would be recorded through earnings as a
component of “Other income (expense), net”. We do not believe there was an “other-than-temporary” decline in value in this security as of
December 31, 2021.

We estimate our annual interest income would change by approximately $30,000 in 2021 for each 100 basis point increase or decrease in interest

rates.

Our exposure to market risk for fluctuations in foreign currency exchange rates relates primarily to the operations of VJCL, for which the

functional currency is the Japanese Yen, and changes in the relative value of the Yen to the U.S. Dollar. Relative to our Yen exposure as of December 31,
2021, we estimate a 10% unfavorable movement in the value of the Yen relative to the U.S. Dollar would increase our foreign currency loss by
approximately $211,000. The functional currency of all other subsidiaries in Europe and other subsidiaries in Asia is the U.S. Dollar. While we believe
risk to fluctuations in foreign currency rates for these subsidiaries is generally not significant, they can be subject to substantial currency changes, and
therefore foreign exchange exposures.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors
Vicor Corporation:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Vicor Corporation and subsidiaries (the Company) as of December 31, 2021 and
December 31, 2020, the related consolidated statements of operations, comprehensive income, cash flows, and equity for each of the years in the three-
year period ended December 31, 2021, and the related notes and financial statement schedule listed in Item 15(a)(2) (collectively, the consolidated
financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company
as of December 31, 2021 and December 31, 2020, and the results of its operations and its cash flows for each of the years in the three-year period ended
December 31, 2021, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s
internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 1, 2022 expressed an
unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent
with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange
Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits
included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures
in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable
basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were
communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated
financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does
not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters
below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Realizability of raw materials inventory

As discussed in Note 2 to the consolidated financial statements, the Company values inventories at the lower of cost, determined using the first-in,
first-out method, or net realizable value. The Company’s estimation process for assessing net realizable value is based upon expected future utility,
which was derived based on backlog, historical consumption and expected market conditions. As disclosed in Note 3 to the consolidated financial
statements, approximately 76%, or $51.3 million, of the Company’s total inventory balance is comprised of raw materials.

We identified the evaluation of the realizability of raw materials inventory to be a critical audit matter. Subjective auditor judgement was required
as a result of uncertainty in market conditions used to estimate forecasted future usage and the long lead times to acquire raw materials within the
global electronics supply chain. Changes in forecasted future usage could have a significant impact on the realizability of raw materials inventory.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating
effectiveness of certain internal controls related to the critical audit matter. This included controls related to the Company’s process to develop its
forecast of usage, including estimates of the projected demand based on historical usage and the potential impact of market conditions. We
evaluated the Company’s estimate of the realizability of raw materials by:

•

•

•

•

  assessing historical consumption as a predictor of future product demand by comparing it to trends in industry publications

  examining the historical accuracy of the Company’s prior estimates by considering subsequent sales and write off activity

  evaluating the adjustments made to forecast future demand based on historical usage data

  interviewing operational personnel of the Company involved in purchasing and manufacturing to evaluate product innovations,

changes in customer mix, and other factors that may impact expected future sales and usage of raw material inventory.

Realizability of domestic deferred tax assets

As discussed in Note 14 to the consolidated financial statements, the Company had a valuation allowance of $43.3 million against all domestic
deferred tax assets, for which realization cannot be considered more likely than not. In assessing the need for a valuation allowance, the Company
considers all positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning
strategies, and past financial performance.

We identified the evaluation of the realizability of the domestic deferred tax assets as a critical audit matter due to the subjectivity involved in
assessing the recoverability of those deferred tax assets. Subjective

auditor judgement was required to evaluate the uncertainty inherent in estimating the Company’s ability to generate sufficient domestic taxable
income exclusive of reversing temporary differences of the appropriate character in the future.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating
effectiveness of certain internal controls related to the Company’s income tax process, including a control related to the assessment of the
realizability of deferred tax assets and the application of relevant tax regulations. To assess the Company’s ability to forecast its financial
performance used to determine future domestic taxable income, we compared the Company’s previous forecasts to actual results, and evaluated
the Company’s consideration of the impact of industry and global economic conditions through inquiry with operational personnel and inspection
of third-party publications. We involved federal and state income tax professionals with specialized skills and knowledge, who assisted in
assessing the Company’s application of the relevant tax regulations and evaluating the realizability of deferred tax assets.

The deferred tax assets associated with cumulative foreign currency translation gains and cumulative unrealized losses on available for sale
securities are completely offset by a tax valuation allowance as of December 31, 2021, 2020, and 2019. Therefore, there is no income tax benefit
(provision) recognized in any of the three years ended December 31, 2021.

1.  DESCRIPTION OF BUSINESS

VICOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Vicor Corporation (the “Company” or “Vicor”) designs, develops, manufactures, and markets modular power components and power systems for

converting electrical power. The Company also licenses certain rights to its technology in return for recurring royalties. The principal markets for the
Company’s power converters and systems are large original equipment manufacturers (“OEMs”), original design manufacturers (“ODMs”) and their
contract manufacturers, and smaller, lower volume users, which are broadly distributed across several major market areas.

2.  SIGNIFICANT ACCOUNTING POLICIES

Principles of consolidation

The Consolidated Financial Statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have

been eliminated upon consolidation.

Use of estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires

management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingencies at the date of
the financial statements and the reported amounts of revenue and expenses during the reporting period. Such estimates and assumptions relate to the
useful lives of fixed assets and identified intangible assets, recoverability of long-lived assets, fair value of short-term and long-term investments,
allowances for doubtful accounts, potential excess, obsolete or unmarketable inventory, potential reserves relating to litigation matters, accrued
liabilities, accrued taxes, deferred tax valuation allowances, assumptions pertaining to share-based payments, and other reserves. Actual results could
differ from those based on these estimates and assumptions, and such differences may be material to the financial statements.

Foreign currency translation

The financial statements of Vicor Japan Company, Ltd. (“VJCL”), a majority-owned subsidiary, for which the functional currency is the Japanese

Yen, have been translated into U.S. Dollars using the exchange rate in effect at the balance sheet date for balance sheet amounts and the average
exchange rates in effect during the year for income statement amounts. The gains and losses resulting from the changes in exchange rates from year to
year have been reported in other comprehensive income.

Transaction gains and losses resulting from the remeasurement of foreign currency denominated assets and liabilities of the Company’s foreign
subsidiaries where the functional currency is the U.S. Dollar are included in other income (expense), net. Foreign currency (losses) gains included in
other income (expense), net, were approximately $(336,000), $181,000, and $(108,000) in 2021, 2020, and 2019, respectively.

Investments

The Company’s principal sources of liquidity are its existing balances of cash and cash equivalents and short-term investments, as well as cash
generated from operations. Consistent with the guidelines of the Company’s investment policy, the Company can invest, and has historically invested, its
cash balances in demand deposit accounts, money market funds, government debt securities, and auction rate securities meeting certain quality criteria.

Cash and Cash Equivalents

VICOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Cash and cash equivalents are highly liquid investments with insignificant interest rate risk and maturities of 90 days or less at the time of
acquisition. Cash and cash equivalents include funds held in disbursement (i.e., checking) and money market accounts, certificates of deposit, and debt
securities with maturities of less than three months at the time of purchase. Cash and cash equivalents are valued at cost, approximating market value.
The Company’s money market securities are purchased and redeemed at par value. Their estimated fair value is equal to their cost, and, due to the nature
of the securities and their classification as cash equivalents, there are no unrealized gains or losses recorded at the balance sheet dates.

Short-term Investments

The Company’s short-term investments, consisting of obligations of the U.S. Treasury, are debt securities with original maturities greater than

three months but less than one year at the time of purchase.

Long-term Investment

The Company’s long-term investment is an auction rate debt security with a maturity of greater than one year and is subject to credit, liquidity,

market, and interest rate risk.

Available-For-Sale Securities

Certain of the cash and cash equivalents, all of the short-term investments and the long-term investment are classified as available-for-sale
securities (“AFS”). These securities are recorded at fair value, with unrealized gains and losses, net of tax, attributable to credit loss recorded through
the Consolidated Statement of Operations and unrealized gains and losses, net of tax, attributable to other non-credit factors recorded in “Accumulated
other comprehensive loss,” a component of Total Equity. Given the nature of the cash and cash equivalents and the short-term investments designated as
AFS, credit losses are not considered to be material. In determining the amount of credit loss for the long-term investment, the Company compares the
present value of cash flows expected to be collected to the amortized cost basis of the security, considering credit default risk probabilities and changes
in credit ratings, among other factors.

The Company periodically evaluates the long-term investment to determine if impairment is required, whether an impairment is other than
temporary, and the measurement of an impairment loss. The Company considers a variety of impairment indicators such as, but not limited to, a
significant deterioration in the earnings performance, credit rating, or asset quality of the investment.

The amortized cost of the debt securities are adjusted for amortization of premiums and accretion of discounts to maturity, the net amount of

which, along with interest and realized gains and losses, is included in “Other income (expense), net” in the Consolidated Statements of Operations.

Fair value measurements  

The Company accounts for certain financial assets at fair value, defined as the price that would be received to sell an asset or paid to transfer a

liability (i.e., an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants
on the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants
would use in pricing an asset or liability. A three-level hierarchy is used to show the extent and level of judgment used to estimate fair value
measurements:  

Level 1

Inputs used to measure fair value are unadjusted quoted prices available in active markets for the identical assets or liabilities as
of the reporting date.

48 

 
  
 
Table of Contents

VICOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Level 2

Level 3

Inputs used to measure fair value, other than quoted prices included in Level 1, are either directly or indirectly observable as of
the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets
and quoted prices in inactive markets. Level 2 also includes assets and liabilities valued using models or other pricing
methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and
volatility factors, are corroborated by readily observable data from actively quoted markets for substantially the full term of the
financial instrument.

Inputs used to measure fair value are unobservable inputs supported by little or no market activity and reflect the use of
significant management judgment. These values are generally determined using pricing models for which the assumptions utilize
management’s estimates of market participant assumptions.

The carrying amounts of cash and cash equivalents, short-term investments, accounts receivable, and accounts payable approximate fair value

because of the short maturities of these financial instruments.

Inventories

Inventories are valued at the lower of cost (determined using the first-in, first-out method) or net realizable value. Fixed production overhead is

allocated to the inventory cost per unit based on the normal capacity of the production facilities. Abnormal production costs, including fixed cost
variances from normal production capacity, if any, are charged to cost of revenues in the period incurred. All shipping and handling costs incurred in
connection with the sale of products are included in cost of revenues.

Inventory estimated to be excess, obsolete, or unmarketable is written down to net realizable value. The Company’s estimation process for
assessing net realizable value is based upon management’s estimate of expected future utility which is derived based on backlog, historical consumption
and expected market conditions. If the Company’s estimated demand and/or market expectations were to change or if product sales were to decline, the
Company’s estimation process may cause larger inventory reserves to be recorded, resulting in larger charges to cost of revenues.

Concentrations of risk

Financial instruments potentially subjecting the Company to significant concentrations of credit risk consist principally of cash and cash

equivalents and short-term investments, of which a significant portion are held by three financial institutions, its long-term investment, and trade
accounts receivable. The Company maintains cash and cash equivalents, short-term investments and certain other financial instruments with high credit
counterparties, and continuously monitors the amount of credit exposure to any one issuer and diversifies its investments in order to minimize its credit
risk. Generally, amounts invested with these financial institutions are in excess of federal deposit insurance limits. The Company has not experienced
any losses in such accounts, and management believes the Company is not exposed to significant credit risk. The Company’s long-term investment as of
December 31, 2021 consists of a single auction rate security with a par value of $3,000,000, which is collateralized by student loans. It is a highly rated
(Aaa/AA+) municipal and corporate debt security. Through December 31, 2021, auctions held for the Company’s auction rate security have failed. The
funds associated with an auction rate security that has failed auction may not be accessible until a successful auction occurs, a buyer is found outside of
the auction process, the security is called, or the underlying securities have matured. If the credit rating of the issuer of the auction rate security held
deteriorates, the Company may be

49

 
  
 
 
  
 
Table of Contents

VICOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

required to adjust the carrying value of the investment for an other-than-temporary decline in value through an impairment charge. The Company’s
investment policy, approved by the Board of Directors, limits the amount the Company may invest in any issuer, thereby reducing credit risk
concentrations.

The Company’s products are sold worldwide to customers ranging from smaller, independent manufacturers of highly specialized electronic
devices, to larger OEMs, ODMs and their contract manufacturers. See Note 17, Segment Information, for a discussion of a change to segment reporting
in the second quarter of 2019. The Company’s Brick Products’ customers are primarily concentrated in the following industries: aerospace and defense
electronics, industrial automation, industrial equipment, instrumentation and test equipment, and transportation (notably in rail and heavy equipment
applications). The Company’s Advanced Products’ customers are concentrated in the data center and hyperscaler segments of enterprise computing, in
which the Company’s products are used for voltage distribution on server motherboards, in server racks, and across datacenter infrastructure The
Company also targets applications in aerospace and aviation, defense electronics, industrial automation, instrumentation, test equipment, solid state
lighting, telecommunications and networking infrastructure, and vehicles (notably in the autonomous driving, electric vehicle, and hybrid vehicle niches
of the vehicle segment). While, overall, the Company has a broad customer base and sells into a variety of industries, a substantial portion of the
Company’s revenue from its Advanced Products line has been derived from a limited number of customers. This concentration of revenue is a reflection
of the relatively early stage of adoption of the technologies, architectures and products offered in the Advanced Products line, and the Company’s
strategy of targeting market leading innovators as initial customers for its Advanced Products. Concentrations of credit risk with respect to trade
accounts receivable are limited due to the number of entities comprising the Company’s customer base. As of December 31, 2021 and 2020, one
customer accounted for approximately 10.0% and 24.1%, respectively, of trade account receivables.

Components and materials used in the Company’s products are purchased from a variety of vendors. While most of the components are available
from multiple sources, some key components for certain Advanced Products, in particular, are supplied by single vendors. In instances of single source
items, the Company maintains levels of inventories management considers appropriate to enable meeting the delivery requirements of customers. If
suppliers or subcontractors cannot provide their products or services on time or to the required specifications, the Company may not be able to meet the
demand for its products and its delivery times may be negatively affected.

Long-lived assets

The Company reviews property, plant and equipment and finite-lived intangible assets for impairment whenever events or changes in

circumstances indicate the carrying value of such assets may not be recoverable. Management determines whether the carrying value of an asset or asset
group is recoverable based on comparison to the undiscounted expected future cash flows the assets are expected to generate over their remaining
economic lives. If an asset value is not recoverable, the impairment loss is equal to the amount by which the carrying value of the asset exceeds its fair
value, which is determined by either a quoted market price, if any, or a value determined by utilizing a discounted cash flow technique. Evaluation of
impairment of long-lived assets requires estimates of future operating results that are used in the preparation of the expected future undiscounted cash
flows. Actual future operating results and the remaining economic lives of our long-lived assets could differ from the estimates used in assessing the
recoverability of these assets. These differences could result in impairment charges, which could be material.

Intangible assets

Values assigned to patents are amortized using the straight-line method over periods ranging from three to 20 years. Patents and other intangible

assets are included in “Other assets” in the accompanying Consolidated Balance Sheets.

Product warranties

VICOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The Company generally offers a two-year warranty for all of its products, though it has extended the warranty period to three years for certain
military grade products. The Company is party to a limited number of supply agreements with certain customers contractually committing the Company
to warranty and indemnification requirements exceeding those to which the Company has been exposed in the past. The Company provides for the
estimated cost of product warranties at the time product revenue is recognized. Factors influencing the Company’s warranty reserves include the number
of units sold, historical and anticipated rates of warranty returns, and the cost per return. The Company periodically assesses the adequacy of warranty
reserves and adjusts the amounts as necessary. Warranty obligations are included in “Accrued expenses” in the accompanying Consolidated Balance
Sheets.

Revenue recognition

Revenue is recognized when control of the promised goods or services is transferred to a customer, in an amount that reflects the consideration the

Company expects to be entitled to in exchange for those goods or services. Sales, value add, and other taxes collected concurrent with revenue
producing activities are excluded from revenue. The expected costs associated with product warranties continue to be recognized at the time product
revenue is recognized. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are
accounted for as a fulfillment cost and are included in cost of revenues.

The Company’s primary source of net revenue comes from the sale of products, which are modular power components and power systems for

converting, regulating and controlling electric current. The principal customers for the Company’s power converters and systems are large OEMs,
ODMs and the original design manufacturers and contract manufacturers serving them, and smaller, lower volume users, which are broadly distributed
across several major market areas. The Company recognizes revenue for product sales at a point in time following the transfer of control of such
products to the customer, including sales to stocking distributors, which typically occurs upon shipment or delivery, depending on the terms of the
underlying contract. The Company establishes sales allowances on shipments to stocking distributors for estimated future product returns including
distributor returns and price adjustment credits, primarily based upon historical and anticipated rates of product returns and allowances.

Certain contracts with customers contain multiple performance obligations, which typically may include a combination of non-recurring
engineering services (“NRE”), prototype units, and production units. For these contracts, the individual performance obligations are accounted for
separately if they are distinct. Generally, the Company has determined the NRE and prototype units represent one distinct performance obligation and
the production units represent a separate distinct performance obligation. For such arrangements, revenue is allocated to each performance obligation
based on its relative standalone selling price, based on prices charged to customers or using the expected cost plus a margin approach. The Company
delays revenue recognition for NRE and prototype units until the point in time at which the final milestone under the NRE arrangement is completed and
control is transferred to the customer, which is generally the shipment or delivery of the prototype. Revenue for production units is recognized upon
shipment or delivery, consistent with product revenue summarized above.

The Company licenses its intellectual property under right to use licenses, in which royalties due to the Company are based upon a percentage of

the licensee’s sales. The Company utilizes the exception under the revenue recognition guidance for the recognition of sales- or usage-based royalties, in
which the royalties are not recognized until the later of when 1) the customer’s subsequent sales or usages occur, or 2) the performance obligation to
which some or all of the sales- or usage-based royalty has been allocated is satisfied or partially satisfied.

Accounts receivable includes amounts billed and currently due from customers. The amounts due are stated at their estimated realizable value.
The Company’s payment terms vary by the type and location of its customers and the products or services offered, although terms generally include a
requirement of payment within 30 to 60 days. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability
of its customers to make required payments, based on assessments of customers’ credit-risk profiles and payment histories. If the financial condition of
the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The
Company does not require collateral from its customers, although there have been circumstances when the Company has required cash in advance (i.e., a
partial down-payment) to facilitate orders in excess of a customer’s established credit limit. To date, such amounts have not been material.

The Company records deferred revenue, which represents a contract liability, when cash payments are received or due in advance of performance
under a contract with a customer. During the years ended December 31, 2021 and 2020, the Company recognized revenue of approximately $4,087,000
and $3,550,000, respectively, that was included in deferred revenue at the beginning of the respective period.

The Company applies the practical expedient for the incremental costs of obtaining a contract for sales commissions, which are expensed when

incurred because the amortization period is generally less than one year. These costs are included in selling, general and administrative expenses.

The Company also applies another practical expedient and does not disclose the value of unsatisfied performance obligations for contracts with an

original expected length of one year or less.

Advertising expense

The cost of advertising is expensed as incurred. The Company incurred approximately $2,994,000, $2,637,000, and $2,749,000 in advertising

costs during 2021, 2020, and 2019, respectively.

Legal Costs

Legal costs in connection with litigation are expensed as incurred.

Stock-based compensation

The Company uses the Black-Scholes option-pricing model to calculate the fair value of stock option awards, whether they possess time-based

vesting provisions or performance-based vesting provisions, and awards granted under the Vicor Corporation 2017 Employee Stock Purchase Plan
(“ESPP”), as of their grant date. For stock options with time-based vesting provisions, the calculated compensation expense, net of expected forfeitures,
is recognized on a straight-line basis over the service period of the award, which is generally five years for stock options. For stock options with
performance-based vesting provisions, recognition of compensation expense, net of expected forfeitures, commences if and when the achievement of the
performance criteria is deemed probable. For stock options with performance-based vesting provisions, compensation expense, net of expected
forfeitures, when recognized, is recognized over the relevant performance period.

Income taxes

Deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and

are measured using the enacted income tax rates and laws expected to

52

 
 
Table of Contents

VICOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

be in effect when the temporary differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance if management determines
it is more likely than not that some portion or all of the deferred tax assets will not be realized. All deferred tax assets and liabilities are classified as
noncurrent.

The Company follows a two-step process to determine the amount of tax benefit to recognize. The first step is to evaluate the tax position to
determine the likelihood it would be sustained upon examination by a tax authority. If the tax position is deemed “more-likely-than-not” to be sustained,
the second step is to assess the tax position to determine the amount of tax benefit to be recognized in the financial statements. The amount of the benefit
that may be recognized is the largest amount that possesses greater than 50 percent likelihood of being realized upon ultimate settlement. If the tax
position does not meet the “more-likely-than-not” threshold, then it is not recognized in the financial statements. Additionally, the Company accrues
interest and penalties, if any, related to unrecognized tax benefits as a component of income tax expense. The unrecognized tax benefits, including
accrued interest and penalties, if any, are included in “Long-term income taxes payable” in the accompanying Consolidated Balance Sheets.

Net income per common share

The Company computes basic net income per share using the weighted average number of common shares outstanding and diluted net income per
share using the weighted average number of common shares outstanding plus the effect of outstanding dilutive stock options, if any. The following table
sets forth the computation of basic and diluted net income per share for the years ended December 31 (in thousands, except per share amounts):

The components of comprehensive income (loss) include, in addition to consolidated net income (loss), unrealized gains and losses on

investments, net of tax and foreign currency translation adjustments related to VJCL, net of tax.

Impact of recently issued accounting standards

In December 2019, the FASB issued guidance designed to simplify the accounting for income taxes by eliminating certain exceptions to the
general principles in Topic 740, Income Taxes, and also improve consistent application of and simplify U.S. GAAP for other areas of Topic 740 by
clarifying and amending existing guidance. This new guidance was effective for the Company for its fiscal year beginning after December 15, 2020,
with early adoption permitted. The Company adopted the new guidance as of January 1, 2021. The adoption did not have a material impact on the
Company’s consolidated financial statements and disclosures.

Other new pronouncements issued but not effective until after December 31, 2021 are not expected to have a material impact on the Company’s

consolidated financial statements.

4.  SHORT-TERM AND LONG-TERM INVESTMENTS

As of December 31, 2021 and 2020, the Company held $45,215,000 and $50,166,000, respectively, of short-term investments, consisting of
obligations of the U.S. Treasury, all of which were debt securities with original maturities greater than three months but less than one year at the time of
purchase.

As of December 31, 2021 and 2020, the Company held one auction rate security with a par value of $3,000,000 and an estimated fair value of

approximately $2,639,000, and $2,517,000, respectively, purchased through and held in custody by a broker-dealer affiliate of Bank of America, N.A.,
that has experienced failed auctions (the “Failed Auction Security”) since February 2008. The Failed Auction Security held by the Company is
Aaa/AA+ rated by major credit rating agencies, is collateralized by student loans, and is guaranteed by the U.S. Department of Education under the
Federal Family Education Loan Program. Management is not aware of any reason to believe the issuer of the Failed Auction Security is presently at risk
of default. Through December 31, 2021, the Company has continued to receive interest payments on the Failed Auction Security in accordance with the
terms of its indenture. Management believes the Company ultimately should be able to liquidate the Failed Auction Security without significant loss
primarily due to the overall quality of the issue held and the collateral securing the substantial majority of the underlying obligation. Changes in the
estimated fair value of the Failed Auction Security have not been significant in the past three years. However, current conditions in the auction rate
securities market have led management to conclude the recovery period for the Failed Auction Security exceeds 12 months. As a result, the Company
continued to classify the Failed Auction Security as long-term as of December 31, 2021.

At this time, the Company has no intent to sell the Failed Auction Security and does not believe it is more likely than not the Company will be

required to sell the security. If current market conditions deteriorate further, the Company may be required to record additional unrealized losses. If the
credit rating of the security deteriorates, the Company may be required to adjust the carrying value of the investment through impairment charges
recorded in the Consolidated Statement of Operations, and any such impairment adjustments may be material.

The Company accounts for certain financial assets at fair value, defined as the price that would be received to sell an asset or paid to transfer a

liability (i.e., an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants
on the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions market participants would
use in pricing an asset or liability. A three-level hierarchy is used to show the extent and level of judgment used to estimate fair value measurements.

Each share of Common Stock entitles the holder thereof to one vote on all matters submitted to the stockholders.

Each share of Class B Common Stock entitles the holder thereof to ten votes on all such matters.

Shares of Class B Common Stock are not transferable by a stockholder except to or among the stockholder’s spouse, certain of the stockholder’s

relatives, and certain other defined transferees. Class B Common Stock is not listed or traded on any exchange or in any market. Class B Common Stock
is convertible at the option of the holder thereof at any time and without cost to the stockholder into shares of Common Stock on a one-for-one basis.

In November 2000, the Board of Directors of the Company authorized the repurchase of up to $30,000,000 of the Company’s Common Stock (the

11.  STOCK-BASED COMPENSATION AND EMPLOYEE BENEFIT PLANS

Vicor currently grants options for the purchase of Common Stock (i.e., “stock options”) under the following equity compensation plans that are

stockholder-approved:

Amended and Restated 2000 Stock Option and Incentive Plan, as amended and restated (the “2000 Plan”) — Under the 2000 Plan, the
Board of Directors or the Compensation Committee of the Board of Directors may grant stock incentive awards based on the Company’s Common
Stock, including stock options, stock appreciation rights, restricted stock, performance shares, unrestricted stock, deferred stock, and dividend
equivalent rights. Awards may be granted to employees and other key persons, including non-employee directors. Incentive stock options may be
granted to employees at a price at least equal to the fair market value per share of the Common Stock on the date of grant, and non-qualified
options may be granted to non-employee directors at a price at least equal to 85% of the fair market value of the Common Stock on the date of
grant. A total of 10,000,000 shares of Common Stock have been reserved for issuance under the 2000 Plan. The period of time during which an
option may be exercised and the vesting periods are determined by the Compensation Committee. The term of each option may not exceed 10
years from the date of grant.

to participate. The ESPP is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code. The ESPP
operates in successive periods of approximately six months, each referred to as an “offering period.” Generally, offering periods commence on or
around September 1 and March 1 and end on or around the following February 28 or August 31, respectively. Under the ESPP, an option is
granted to participating employees on the first day of an offering period to purchase shares of the Company’s Common Stock at the end of that
offering period at a purchase price equal to 85% of the lesser of the fair market value of a share of Common Stock on either the first day or the last
day of that offering period. The purchase of shares is funded by means of periodic payroll deductions, which may not exceed 15.0% of the
employee’s eligible compensation, as defined in the Plan. Among other provisions, the Plan limits the number of shares that can be purchased by a
participant during any offering period and cumulatively for any calendar year.

VI Chip was a privately held, majority-owned subsidiary of Vicor until June 28, 2019, at which date it was merged with and into Vicor, and its

separate corporate existence ceased (see Note 18). Until that time, VI Chip could grant stock options under the VI Chip Corporation Amended and
Restated 2007 Stock Option and Incentive Plan (the “2007 VI Chip Plan”), that had been approved by its Board of Directors. All awards thereunder
were approved by the Compensation Committee of the Company’s Board of Directors. To effect the merger, holders of VI Chip common stock and VI
Chip stock options received an equivalent value of Vicor Common Stock and Vicor stock options, respectively, pursuant (with respect to the stock
options) to the assumption of the 2007 VI Chip Plan, and options outstanding thereunder, by Vicor. No additional awards will be granted under the
assumed and restated 2007 VI Chip Plan.

Picor was a privately held, majority-owned subsidiary of Vicor until May 30, 2018, at which date it was merged with and into Vicor, and its
separate corporate existence ceased (see Note 18). Until that time, Picor could grant stock options under the Picor Corporation Amended and Restated
2001 Stock Option and Incentive Plan (the “2001 Picor Plan”) that had been approved by its Board of Directors. All awards thereunder were approved
by the Compensation Committee of the Company’s Board of Directors. To effect the merger, holders of Picor common stock and Picor stock options
received an equivalent value of Vicor Common Stock and Vicor stock options, respectively, pursuant (with respect to the stock options) to the
assumption of the 2001 Picor Plan, and options outstanding thereunder, by Vicor. No additional awards will be granted under the assumed and restated
2001 Picor Plan.

All time-based (i.e., non-performance-based) options for the purchase of Vicor common stock are granted at an exercise price equal to or greater

than the market price for Vicor Common Stock at the date of the grant. All time-based (i.e., non-performance-based) options for the purchase of VI Chip
common stock and Picor common stock prior to the mergers and assumptions of the 2007 VI Chip Plan and of the 2001 Picor Plan, respectively, had
been granted at an exercise price equal to or greater than the estimated fair market value of the respective share price, based on valuation methodologies
consistent with U.S. GAAP and the requirements of Section 409A of the Internal Revenue Code, as amended (the “Code”).

VICOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The increase in stock option compensation expense in 2021 compared to 2020, was primarily due to an increase in the number of stock

options granted and higher stock-based compensation expense associated with June 2021 stock option awards.

Compensation expense by type of award for the years ended December 31 was as follows (in thousands):

Stock options

$3,036 

The fair value for non-performance-based stock options awarded under the 2000 Plan for the years shown below was estimated at the date of grant

using the Black-Scholes option pricing model with the following weighted-average assumptions:

Risk-free interest rate
Expected dividend yield
Expected volatility
Expected lives (years)

Risk-free interest rate:

2021 
  0.8%  
  — 
  49%  
  4.9 

2020 
  0.5%  
  — 
  48%  
  6.1 

2019 
  1.8% 
  — 
  42% 
  6.3 

The Company uses the yield on zero-coupon U.S. Treasury “Strip” securities for a period that is commensurate with the expected term assumption

for each vesting period.

Expected dividend yield:

The Company determines the expected dividend yield by annualizing the most recent prior cash dividends declared by the Company’s Board of

Directors, if any, and dividing that result by the closing stock price on the date of that dividend declaration. Dividends are not paid on options.

Expected volatility:

Vicor uses historical volatility to estimate the grant-date fair value of the options, using the expected term for the period over which to calculate
the volatility (see below). The Company does not expect its future volatility to differ from its historical volatility. The computation of the Company’s
volatility is based on a simple average calculation of monthly volatilities over the expected term.

Expected term:

The Company uses historical employee exercise and option expiration data to estimate the expected term assumption for the Black-Scholes grant-
date valuation. The Company believes this historical data is currently the best estimate of the expected term of options, and all groups of the Company’s
employees exhibit similar exercise behavior.

Forfeiture rate:

The amount of stock-based compensation recognized during a period is based on the value of the portion of the awards that are ultimately

expected to vest. Forfeitures are estimated at the time of grant and revised, if

necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” or “expirations”
and represents only the unvested portion of the surrendered option. The forfeiture analysis is re-evaluated annually and the forfeiture rate is adjusted as
necessary. Ultimately, the actual expense recognized over the vesting period will only be for those shares that vest.

Based on an analysis of historical forfeitures, the Company applied an annual forfeiture rate of 4.85% in 2021, estimating approximately 86% of

its options would actually vest. For 2020 and 2019, the Company applied an annual forfeiture rate of 5.25%, estimating approximately 85% of its
options would actually vest in those two years. 

A summary of the activity under the 2000 Plan as of December 31, 2021 and changes during the year then ended, is presented below (in thousands

In addition to the vested options, the Company expects a portion of the unvested options to vest at some point in the future. The number of options
expected to vest is calculated by applying an estimated forfeiture rate to the unvested options.

As of December 31, 2020 and 2019, the Company had options exercisable for 924,964 and 1,475,947 shares respectively, for which the weighted

average exercise prices were $9.05 and $8.74, respectively.

During the years ended December 31, 2021, 2020, and 2019, the total intrinsic value of Vicor options exercised (i.e., the difference between the

market price at exercise and the price paid by the employee to exercise the options) was approximately $56,933,000, $50,410,000, and $6,636,000,
respectively. The total amount of cash received by the Company from options exercised in 2021, 2020, and 2019, was $7,616,000, $9,127,000, and
$2,437,000, respectively. The total grant-date fair value of stock options granted during the years ended December 31, 2021, 2020, and 2019 was
approximately $10,506,000, $10,847,000, and $1,657,000, respectively.

As of December 31, 2021, there was approximately $15,019,000 of total unrecognized compensation cost related to unvested non-performance

based awards for Vicor. That cost is expected to be recognized over a weighted-average period of 1.6 years for those awards. The expense will be
recognized as follows: $6,837,000 in 2022, $4,142,000 in 2023, $2,478,000 in 2024, $1,260,000 in 2025, and $302,000 in 2026.

The weighted-average fair value of Vicor options granted was $39.27, $30.63, and $14.30, in 2021, 2020, and 2019, respectively.

401(k) Plan

VICOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The Company sponsors a savings plan available to all domestic employees, which qualifies under Section 401(k) of the Code. Employees may

contribute to the plan in amounts representing from 1% to 80% of their pre-tax salary, subject to statutory limitations. The Company matches employee
contributions to the plan at a rate of 50%, up to the first 6% of an employee’s compensation. The Company’s matching contributions currently vest at a
rate of 20% per year, based upon years of service. The Company’s contributions to the plan were approximately $1,593,000, $1,031,000, and $1,001,000
in 2021, 2020, and 2019, respectively.

Stock Bonus Plan

Under the Company’s 1985 Stock Bonus Plan, as amended, shares of Common Stock may be awarded to employees from time to time as
determined by the Board of Directors. On December 31, 2021, 109,964 shares were available for further award. All shares awarded to employees under
this plan have vested. No further awards are contemplated under this plan at the present time.

12.  LEASES

Substantially all of the Company’s leases are classified as operating leases. The majority of the Company’s leases are for office and manufacturing
space, along with several automobiles and certain equipment. Leases with initial terms of less than twelve months are not recorded on the balance sheet.
Expense for these leases is recognized on a straight-line basis over the lease term. The Company’s leases have remaining terms of less than one year to
just over six years. The majority of the Company’s leases do not have options to renew, although several have renewal terms to extend the lease for one
five-year term, and one lease contains two five-year renewal options. None of the renewal options are included in determining the term of the lease, used
for calculating the associated lease liabilities. None of the Company’s leases include variable payments, residual value guarantees or restrictive
covenants. A number of the Company’s leases for office and manufacturing space include provision for common area maintenance (“CAM”). The
Company accounts for CAM separately from lease payments, and therefore costs for CAM are not included in the determination of lease liabilities. The

As of December 31, 2021, the Company has a valuation allowance of approximately $43,329,000 against all net domestic deferred tax assets, for
which realization cannot be considered more likely than not at this time. Management assesses the need for the valuation allowance on a quarterly basis.
In assessing the need for a valuation allowance, the Company considers all positive and negative evidence, including scheduled reversals of deferred tax
liabilities, projected future taxable income, tax planning strategies, and past financial performance. Despite recent positive operating results, as a result
of increases in bookings, the Company is in a cumulative loss position as of December 31, 2021, primarily due to tax deductions on 2020 and 2021
exercises of stock-based compensation. The Company faces uncertainties in forecasting its operating results due to vendor supply and factory capacity
constraints, certain process issues with the production of Advanced Products and the unpredictability in certain markets. This operating uncertainty also
makes it difficult to predict the availability and utilization of tax benefits over the next several years. As a result, management has concluded, at this
time, is more likely than not the Company’s net domestic deferred tax assets will not be realized, and a full valuation allowance against all net domestic
deferred tax assets is still warranted as of December 31, 2021. The valuation allowance against these deferred tax assets may require adjustment in the
future based on changes in the mix of temporary differences, changes in tax laws, and operating performance. If the positive operating results and
increases in bookings continue, and the Company’s concerns about industry uncertainty and world events, supply and capacity constraints, and process
issues with the production of Advanced Products are resolved, and the amount of tax benefits the Company is able to utilize to the point that the
Company believes future taxable income can be more reliably forecasted, the Company may release all or a portion of the valuation allowance in the
near-term. Certain state tax credits, though, will likely never be released by the valuation allowance. If and

when the Company determines the valuation allowance should be released (i.e., reduced), the adjustment would result in a tax benefit reported in that
period’s Consolidated Statements of Operations, the effect of which would be an increase in reported net income.

The state and federal research and development tax credit carryforwards of approximately $13,970,000 and $24,807,000, respectively, expire

beginning in 2021 for state purposes and in 2025 for federal purposes. The Company has federal net operating loss carryforwards generated after 2017
of approximately $25,963,000, which have an indefinite carryforward period and certain state operating loss carryforwards of approximately
$24,804,000, which expire beginning in 2025.

The Company has reviewed the tax positions taken, or to be taken, in its tax returns for all tax years currently open to examination by a taxing
authority. The total amount of unrecognized tax benefits, that is the aggregate tax effect of differences between tax return positions and the benefits
recognized in the Company’s financial statements, as of December 31, 2021, 2020, and 2019 of $3,246,000, $2,297,000, and $2,070,000, respectively, if
recognized, may decrease the Company’s income tax provision and effective tax rate. None of the unrecognized tax benefits as of December 31, 2021
are expected to significantly change during the next twelve months.

The Company recognizes accrued interest and penalties, if any, related to unrecognized tax benefits as a component of income tax expense.
During the years ended December 31, 2021, 2020, and 2019, the Company recognized approximately $19,000, $17,000, and $7,000, respectively, in net
interest expense. As of December 31, 2021 and 2020, the Company had accrued approximately $52,000 and $58,000, respectively, for the potential
payment of interest.

The Company files income tax returns in the United States and various foreign tax jurisdictions. These tax returns are generally open to

examination by the relevant tax authorities from three to seven years from the date they are filed. The tax filings relating to the Company’s federal and
state taxes are currently open to examination for tax years 2018 through 2020 and 2012 through 2020, respectively. In addition, the Company generated
federal research and development credits in tax years 2005 through 2017. These years may also be subject to examination when the credits are carried
forward and utilized in future years.

The Company was informed in September 2021 by the Internal Revenue Service of their intention to examine the Company’s 2019 Federal

income tax return. The examination is in its early stages. There are no other audits or examinations in process in any other jurisdiction.

approximately $4,803,000 of capital expenditure items which had been received and included in Property, plant and equipment in the accompanying
Consolidated Balance Sheets, but not yet paid for. 

The Company is the defendant in a patent infringement lawsuit originally filed on January 28, 2011 by SynQor, Inc. (“SynQor”) in the U.S.
District Court (the “District Court”) for the Eastern District of Texas (the “Texas Action”). The complaint, as amended, alleges that the Company’s
products, including but not limited to, unregulated bus converters used in intermediate bus architecture power supply systems, infringe SynQor’s U.S.
patent numbers 7,072,190, 7,272,021, 7,564,702, and 8,023,290 (“the ‘190 patent”, “the ‘021 patent”, “the ‘702 patent”, and “the ‘290 patent”,
respectively). SynQor’s complaint sought an injunction against further infringement and an award of unspecified compensatory and enhanced damages,
interest, costs and attorney fees. The Company has denied that its products infringe any of the SynQor patents, and has asserted that the SynQor patents
are invalid and/or unenforceable. The Company has also asserted counterclaims seeking damages from SynQor for deceptive trade practices and tortious
interference with prospective economic advantage arising from SynQor’s attempted enforcement of its patents against the Company.

On November 24, 2015, the District Court ordered the Texas Action stayed pending completion of certain inter partes reexamination (“IPRx”)

proceedings initiated by the Company at the United States Patent and Trademark Office (“USPTO”). In these IPRx proceedings, the Company
challenged the validity of the SynQor patent claims asserted in the Texas Action. On November 16, 2021 the District Court issued an order lifting the
stay. At a hearing on February 2, 2022, the District Court issued an order denying all pending summary judgment and other pre-trial motions without
prejudice, and instructed the parties to propose a new case schedule with a trial date of October 17, 2022. The District Court further authorized Vicor to
file new motions for summary judgment, to be considered on an expedited schedule. Vicor filed a motion for summary judgment of non-infringement on
February 4, 2022. The Court has not yet ruled on that motion.

The current status of the IPRx proceedings is as follows:

•

•

•

•

  190 patent: Certain claims of the ‘190 patent were found unpatentable by the Federal Circuit Court of Appeals (“Federal Circuit”) in a
decision issued on March 13, 2015. The court remanded the remaining claims to the USPTO for further consideration. On February 20,
2019, the Patent Trial and Appeal Board (“PTAB”) of the USPTO issued a decision finding that all of the remaining challenged claims
were unpatentable. SynQor appealed that decision. On February 22, 2021, the Federal Circuit issued a decision in that appeal. In a 2-1
ruling, the Federal Circuit vacated and remanded the PTAB’s decision, finding that the reasoning the PTAB had relied on in reaching its
decision was precluded by certain prior PTAB rulings regarding the ‘290 and ‘702 patents and remanded the case to the PTAB for further
proceedings. On April 7, 2021, the Company filed a petition for panel rehearing and rehearing en banc of the Federal Circuit’s
February 22, 2021 decision. The Federal Circuit denied that petition on June 7, 2021. Accordingly, that matter has been remanded to the
PTAB for further proceedings.

  ‘021 patent: On August 30, 2017, the Federal Circuit issued a final decision finding all of the asserted claims of the ‘021 patent

unpatentable.

  ‘702 patent: On August 30, 2017, the Federal Circuit issued a final decision finding all of the asserted claims of the ‘702 patent to be

patentable.

  ‘290 patent: On June 16, 2021, the PTAB issued a decision finding all of the claims of the ‘290 patent unpatentable. SynQor has filed an

appeal of that decision to the Federal Circuit, where it remains pending.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

On January 23, 2018, the 20-year terms of the ‘190 patent, the ‘021 patent, the ‘702 patent and the ‘290 patent expired. As a consequence of these

expirations, the Company cannot be liable under any of the SynQor patents for allegedly infringing activities occurring after that date. In addition, any
amended claims that may issue as a result of any of the still-pending IPRx proceedings will have no effective term and cannot be the basis for any
liability by the Company. As noted above, the IPRx’s relating to the asserted claims of the ‘190 and ‘290 patents remain pending or on appeal. In
addition, SynQor attempted to add new claims during the IPRx of the ‘021 patent. Those claims were rejected by the PTAB. SynQor subsequently filed
an appeal with the Federal Circuit seeking to vacate that rejection as moot, in view of the expiry of the term of the ‘021 patent, and that appeal remains
pending.

The Company continues to believe none of its products, including its unregulated bus converters, infringe any valid claim of the asserted SynQor

patents, either alone or when used in an intermediate bus architecture implementation. The Company believes SynQor’s claims lack merit and, therefore,
it continues to vigorously defend itself against SynQor’s patent infringement allegations. The Company does not believe a loss is probable or reasonably
possible for this matter. If a loss were to be incurred, however, the Company cannot estimate the amount of possible loss or range of possible loss at this
time.

In addition to the SynQor matter, the Company is involved in certain other litigation and claims incidental to the conduct of its business. While the

outcome of lawsuits and claims against the Company cannot be predicted with certainty, management does not expect any current litigation or claims
will have a material adverse impact on the Company’s financial position or results of operations.

16.  VI CHIP MERGER

On June 28, 2019, the Company’s Board of Directors unanimously approved the merger of VI Chip, a subsidiary of Vicor that was fully
consolidated for financial reporting purposes, with and into the Company. The merger was completed as of June 28, 2019, at which time the separate
corporate existence of VI Chip ceased. To effect the merger, holders of VI Chip common stock and VI Chip stock options received an equivalent value
of Vicor Common Stock and Vicor stock options, respectively, pursuant (with respect to the stock options) to the assumption of the 2007 VI Chip Plan,
and options outstanding thereunder, by the Company.

There was no net impact on the Company’s consolidated financial statements for the year ended December 31, 2019 as a result of the merger.

17.  SEGMENT INFORMATION

In the second quarter of 2019, management determined, with the approval of the Company’s Board of Directors and Chief Operating Decision

Maker (“CODM”), Dr. Vinciarelli, the Company would report as one segment, rather than under the three segment approach previously employed since
2007. The Company’s strategy had evolved with a transition in organizational focus, emphasizing investment in Advanced Products, targeting high
growth market segments with a low-mix, high-volume operational model, while maintaining a profitable business in mature market segments the
Company serves with Brick Products with a high-mix, low-volume operational model. Dr. Vinciarelli and management began to make incremental
changes in management practices and organizational structure based on a management plan established in 2018 for the definitive reconfiguration of the
three business units into one business focused on the Advanced Products and Brick Products product line categorizations, including three significant
changes: the merger of Picor with and into Vicor, which was completed on May 25, 2018; the reconfiguration of the Company’s internal reporting
systems, which was completed on December 31, 2018; and the merger of VI Chip with and into Vicor, which was completed on June 28, 2019. Our
CODM now determines the allocation of resources of the Company based upon the two

product groupings, which constitute one segment. Both product lines are built in the Company’s manufacturing facility in Andover, Massachusetts
employing similar processing and production techniques, and are supported by the same sales and marketing organizations. As such, the Company has
conformed the segment reporting to the new reporting structure utilized by the CODM. Accordingly, three-segment information for prior periods has not
been presented, to conform with the new presentation.

ITEM 9A.

CONTROLS AND PROCEDURES

Attached as exhibits to this Annual Report on Form 10-K are certifications of our CEO and Chief Financial Officer (“CFO”), which are required

in accordance with Rule 13a-14 of the Exchange Act. This “Controls and Procedures” section includes information concerning the controls and controls
evaluation referred to in the certifications.

(a) Evaluation of disclosure controls and procedures

As required by Rule 13a-15 under the Exchange Act, management, with the participation of our CEO and CFO, conducted an evaluation regarding

the effectiveness of our disclosure controls and procedures, as of the end of the last fiscal year. The term “disclosure controls and procedures,” as
defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that
information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and
reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include,
without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or
submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal
financial officers, as appropriate to allow timely decisions regarding required disclosure. We recognize any controls and procedures, no matter how well
designed and operated, can provide only reasonable assurance of achieving their objectives and we necessarily apply our judgment in evaluating the
cost-benefit relationship of possible controls and procedures. Based on the evaluation of the Company’s disclosure controls and procedures as of
December 31, 2021, the CEO and CFO concluded, as of such date, the Company’s disclosure controls and procedures were effective at the reasonable
assurance level.

(b) Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance

regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally
accepted accounting principles. Internal control over financial reporting includes those policies and procedures: (a) pertaining to the maintenance of
records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; (b) providing reasonable assurance that
transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and
that receipts and expenditures are being made only in accordance with authorizations of our management and Board of Directors; and (c) providing
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material
effect on our financial statements.

Management assessed our internal control over financial reporting as of December 31, 2021, the end of our fiscal year. Management based its
assessment on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the
Treadway Commission (“COSO”). Management’s assessment included evaluation of such elements as the design and operating effectiveness of key

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors
Vicor Corporation:

Opinion on Internal Control Over Financial Reporting

We have audited Vicor Corporation and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2021, based on criteria
established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In
our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on
criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway
Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated
balance sheets of the Company as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive income, cash
flows, and equity for each of the years in the three-year period ended December 31, 2021, and the related notes and financial statement schedule listed in
Item 15(a)(2) (collectively, the consolidated financial statements), and our report dated March 1, 2022 expressed an unqualified opinion on those
consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness
of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our
responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm
registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal
control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material
weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included
performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our
opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s
internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and
expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a
material effect on the financial statements.

75

 
Table of Contents

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation
of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

(c) Inherent Limitations on Effectiveness of Controls

The Company’s management, including the CEO and CFO, does not expect that our disclosure controls or our internal control over financial

reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not
absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource
constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no
evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of
fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty
and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by
collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain
assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all
potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become
inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

(d) Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the fiscal quarter ended December 31, 2021, that has

materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

SUMMARY OF COMPENSATION AGREEMENT
BETWEEN VICOR CORPORATION AND ANDREW D’AMICO

Exhibit 10.13

The following is a description of the compensation agreement between Vicor Corporation (the “Company”) and Andrew D’Amico, provided pursuant to
Item 601(b)(10)(iii)(A) of Regulation S-K promulgated by the Securities and Exchange Commission, which requires a written description of a
compensatory agreement when no formal document exists.

Mr. D’Amico has served in the role of general counsel for the Company for intellectual property matters since January 2006. Pursuant to an informal
compensation agreement between the Company and Mr. D’Amico (the “Agreement”), in exchange for his services as general counsel, the Company has
agreed to pay Mr. D’Amico a fee of $31,000 per month (subject to annual adjustment), as well as reimbursement of expenses incurred in connection
with his provision of services to the Company. Also pursuant to the Agreement, Mr. D’Amico is entitled to an incentive fee equal to 3% of the royalties
received by the Company pursuant to certain license agreements negotiated by Mr. D’Amico on behalf of the Company. The aggregate amount of such
incentive fees is limited to $1,000,000, although this amount may be increased by mutual agreement in certain circumstances, including the negotiation
of additional license agreements by Mr. D’Amico. As of December 31, 2021, the amount of such incentive fees payable to Mr. D’Amico is immaterial.
The Company expects to continue the Agreement, under the same terms and conditions, for the remainder of 2022.

Mr. D’Amico also serves as a non-employee director of the Company and, as such, he is eligible to participate in, and receive cash and equity
compensation in accordance with, the Company’s standard non-employee director compensation programs.
