Notes to Condensed Consolidated Financial Statements

March 31, 2023

(unaudited)

1. Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements of Vicor Corporation and its consolidated subsidiaries (collectively, the “Company”) have been prepared in accordance with generally accepted accounting principles for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, these interim financial statements do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.

In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for any other interim period or the year ending December 31, 2023. The balance sheet at December 31, 2022 presented herein has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. For further information, refer to the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 filed by the Company with the SEC on February 28, 2023 (“2022 Form 10-K”).

2. Inventories

Inventories were as follows (in thousands):

	March 31, 2023		December 31, 2022
Raw materials	$	85,833	$	82,181
Work-in-process		12,101		10,456
Finished goods		9,448		8,773
	$	107,382	$	101,410

3. Long-Term Investments

As of March 31, 2023 and December 31, 2022, the Company held one auction rate security with a par value of $3,000,000 and an estimated fair value of approximately $2,631,000 and $2,622,000, 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 March 31, 2023, 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. 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 March 31, 2023.

4. 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 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.

Assets and liabilities measured at fair value on a recurring basis included the following as of March 31, 2023 (in thousands):

The effective tax rates were lower than the statutory tax rates for the three months ended March 31, 2023 and 2022 primarily due to the Company’s full valuation allowance position against domestic deferred tax assets. The provision (benefit) for income taxes for the three months ended March 31, 2023 and 2022 included estimated federal, state and foreign income taxes in jurisdictions in which the Company does not have sufficient tax attributes.

As of March 31, 2023, the Company has a valuation allowance of approximately $47,413,000 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, the Company faces uncertainties in forecasting its operating results due to 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, as of March 31, 2023, it 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 March 31, 2023. 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 continue, and the Company’s concerns about industry uncertainty and world events, supply and factory 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. 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 Condensed Consolidated Statements of Operations, the effect of which would be an increase in reported net income.

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 IRS is in the process of closing examination of the 2019 tax year with no material adjustments. There are no other audits or examinations in process in any other jurisdiction.

Diluted net income per share	$	0.25	$	0.11

(1) Denominator represents the weighted average number of shares of Common Stock and Class B Common Stock outstanding. 

(2) Options to purchase 1,035,618 and 291,880 shares of Common Stock for the three months ended March 31, 2023 and 2022, respectively, were not included in the calculations of net income per share as the effect would have been antidilutive.

10. Commitments and Contingencies

At March 31, 2023, the Company had approximately $19,325,000 of cancelable and non-cancelable capital expenditure commitments, principally for manufacturing equipment, and approximately $2,083,000 of capital expenditure items which had been received and included in Property, plant and equipment in the accompanying Condensed 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 complaint, as amended, alleged that the Company’s unregulated bus converters used in intermediate bus architecture power supply systems infringed 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, and collectively the “SynQor Patents”). The Company asserted counterclaims against SynQor alleging unfair competition and tortious interference with business relations (the “Counterclaims”). As a result of certain actions by the United States Patent and Trademark Office (“USPTO”) and the District Court, SynQor’s infringement allegations regarding the ‘021 patent and the ‘290 patent were dismissed from the case prior to the beginning of trial. Specifically, the USPTO invalidated all the asserted claims of the ‘021 patent and that decision was upheld on appeal on August 30, 2017. In addition, on October 5, 2022, the District Court issued

-14-

VICOR CORPORATION

Notes to Condensed Consolidated Financial Statements

(unaudited)

an order involuntarily dismissing the ‘290 patent infringement allegations on grounds of equitable and judicial estoppel, in view of representations by SynQor to the District Court agreeing to such dismissal as a condition of lifting a prior stay of the lawsuit. On January 18, 2023, the United States Court of Appeals for the Federal Circuit issued a decision upholding a decision of the Patent Trial and Appeal Board of the USPTO invalidating all claims of the ‘290 patent.

A trial in the District Court began on October 17, 2022 on the asserted claims of the ‘190 patent and the ‘702 patent, as well as on the Company’s Counterclaims. The District Court dismissed the Company’s Counterclaims on October 25, 2022. On October 26, 2022, the jury returned a verdict on SynQor’s patent infringement claims, finding that the Company willfully infringed the ‘702 patent, but did not infringe the ‘190 patent. The jury awarded SynQor damages in the amount of $6,500,000 for infringement of the ‘702 patent. All of the SynQor Patents expired in 2018.

On December 23, 2022, SynQor filed in the District Court (a) a motion for judgment as a matter of law that the Company infringed the ‘190 patent, (b) a motion requesting the District Court to award SynQor treble damages, as well as pre- and post-judgment interest, (c) a motion requesting the District Court to award SynQor its attorneys’ fees, and (d) a motion for a new trial. On December 23, 2022, the Company filed in the District Court (a) a motion requesting judgment as a matter of law that it did not infringe the ‘702 patent, and (b) a motion requesting judgment with respect to its defenses of equitable estoppel and waiver. The Court has not yet acted on any of these motions. To the extent that the District Court ultimately rules against the Company with respect to any of the aforementioned motions, the Company anticipates appealing those rulings to the United States Court of Appeals for the Federal Circuit. The Company similarly anticipates appealing the District Court’s order dismissing the Company’s Counterclaims against SynQor.

In accordance with applicable accounting standards, the Company recorded a litigation related accrual of $6,500,000 in the third quarter of 2022 as its estimate based on the jury award, using estimated outcomes ranging from $0 to treble damages plus attorney fees.

In addition, the Company is involved in certain other litigation and claims incidental to the conduct of its business. While the outcome of such other lawsuits and claims against the Company cannot be predicted with certainty, management does not expect such litigation or claims will have a material adverse impact on the Company’s financial position or results of operations.

11. Impact of Recently Issued Accounting Standards

New pronouncements issued but not effective until after March 31, 2023 are not expected to have a material impact on the Company’s consolidated financial statements.

Management’s Discussion and Analysis of

Financial Condition and Results of Operation

March 31, 2023

Overview

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 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. Supply chain disruptions, including those associated with our reliance on outsourced package process steps that are essential in the production of some of our Advanced Products, and those relating, for example, to the procurement of raw material, have in the past negatively impacted and may in the

future negatively impact our operating results. We have taken steps to mitigate the impact of supply chain disruptions by, among other things and in varying degrees, moving outsourced manufacturing steps in-house to the Company, ordering supplies with extended lead times, paying higher prices for certain supplies or outsourced production, and expediting deliveries at a cost premium. The resulting impact of the steps taken to mitigate supply chain disruptions have, to varying degrees and at different times, reduced our revenue, gross margin, operating profit and cash flow and may continue to do so in the future. While we continue to make progress in moving outsourced manufacturing steps in-house to the Company, we are still experiencing long lead times on certain raw material components, and uncertainty of output from our outsourced manufacturing supplier. 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. 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 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, have resulted and may continue to result in higher costs and inbound and outbound delays.

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.

Summary of First Quarter 2023 Financial Performance Compared to Fourth Quarter 2022 Financial Performance

The following summarizes our financial performance for the first quarter of 2023, compared to the fourth quarter of 2022:

• Net revenues decreased 7.3% to $97,816,000 for the first quarter of 2023, from $105,493,000 for the fourth quarter of 2022. Net revenues for Brick Products increased 10.9% compared to the fourth quarter of 2022, primarily due to the ability to shift manufacturing resources to focus on available backlog, as well as favorable market conditions. Advanced Products net revenue decreased 19.3% compared to the fourth quarter of 2022 primarily due to continued supply constraints leading to longer cycle-times and schedule delays.

• Export sales represented approximately 64.3% of total net revenues in the first quarter of 2023 as compared to 59.8% in the fourth quarter of 2022.

• Gross margin decreased to $46,534,000 for the first quarter of 2023 from $49,139,000 for the fourth quarter of 2022, but gross margin, as a percentage of net revenues, increased to 47.6% for the first quarter of 2023 from 46.6% for the fourth

quarter of 2022. The decrease in gross margin dollars and the increase in gross margin percentage were primarily a result of the unfavorable impact from lower sales volume offset by reduced freight-in and tariff spending of $3,927,000 (net of approximately $3,000,000 in duty drawback recovery of previously paid tariffs).

• Backlog, which represents the total value of orders for products for which shipment is scheduled within the next 12 months, was approximately $271,283,000 at the end of the first quarter of 2023, as compared to $304,392,000 at the end of the fourth quarter of 2022.

• Operating expenses for the first quarter of 2023 decreased $4,928,000, or 12.0%, to $36,092,000 from $41,020,000 for the fourth quarter of 2022. Selling, general, and administrative expenses decreased approximately $4,719,000, primarily due to a decrease in legal fees. Research and development expenses decreased approximately $209,000, primarily due to a decrease in engineering supplies.

• We reported net income for the first quarter of 2023 of $11,244,000, or $0.25 per diluted share, compared to net income of $8,062,000, or $0.18 per diluted share, for the fourth quarter of 2022.

• For the first quarter of 2023, depreciation and amortization totaled $4,199,000 and capital additions totaled $10,089,000 as compared to depreciation and amortization of $3,526,000 and capital additions of $12,687,000 for the fourth quarter of 2022.

• Inventories increased by approximately $5,972,000, or 5.9%, to $107,382,000 at March 31, 2023, compared to $101,410,000 at December 31, 2022, primarily consisting of raw materials.

Three Months Ended March 31, 2023 Compared to Three Months Ended March 31, 2022

Net revenues for the first quarter of 2023 were $97,816,000, an increase of $9,534,000, or 10.8%, as compared to $88,282,000 for the first quarter of 2022. Net revenues, by product line, for the three months ended March 31, 2023 and 2022 were as follows (dollars in thousands):

					Increase (decrease)
	2023		2022		$			%
Advanced Products	$	51,291	$	52,925	$	(1,634	)		(3.1	)%
Brick Products		46,525		35,357		11,168			31.6	%
Total	$	97,816	$	88,282	$	9,534			10.8	%

The decrease in net revenues for Advanced Products was primarily due to manufacturing constraints and schedule delays. The increase in net revenues for Brick Products was primarily due to the ability to shift manufacturing resources to focus on available backlog, as well as favorable market conditions.

Gross margin for the first quarter of 2023 increased $8,933,000, or 23.8%, to $46,534,000, from $37,601,000 for the first quarter of 2022. Gross margin, as a percentage of net revenues, increased to 47.6% for the first quarter of 2023, compared to 42.6% for the first quarter of 2022. The increase in gross margin dollars and gross margin percentage was primarily due to favorable higher sales volume, improved production efficiencies, and reduced freight-in and tariff spending of $3,791,000 (net of approximately $3,000,000 in duty drawback recovery of previously paid tariffs), partially offset by an unfavorable sales mix.

The effective tax rates were lower than the statutory tax rates for the three months ended March 31, 2023 and 2022 primarily due to the Company’s full valuation allowance position against domestic deferred tax assets. The provision (benefit) for income taxes for the three months ended March 31, 2023 and 2022 included estimated federal, state and foreign income taxes in jurisdictions in which the Company does not have sufficient tax attributes.

See Note 8 to the Condensed 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.

We reported net income for the first quarter of 2023 of $11,244,000, or $0.25 per diluted share, compared to $4,999,000, or $0.11 per diluted share, for the first quarter of 2022.

As of March 31, 2023, we had $192,897,000 in cash and cash equivalents. The ratio of total current assets to total current liabilities was 6.8:1 as of March 31, 2023 and 5.6:1 as of December 31, 2022. Working capital, defined as total current assets less total current liabilities, increased $14,643,000 to $312,698,000 as of March 31, 2023 from $298,055,000 as of December 31, 2022.

The changes in working capital from December 31, 2022 to March 31, 2023 were as follows (in thousands):

	Increase (decrease)
Cash and cash equivalents	$	2,286
Accounts receivable		(4,368	)
Inventories		5,972
Other current assets		(124	)
Accounts payable		5,417
Accrued compensation and benefits		(475	)
Accrued expenses		3,844
Short-term deferred revenue		3,432
Other		(1,341	)
	$	14,643

The primary sources of cash for the three months ended March 31, 2023 were $10,113,000 generated from operations, and $2,261,000 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 three months ended March 31, 2023 were for the purchase of property and equipment of $10,089,000.

In November 2000, our Board of Directors authorized the repurchase of up to $30,000,000 of our 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 and amounts of Common Stock repurchases 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 three months ended March 31, 2023. As of March 31, 2023, we had approximately $8,541,000 remaining available for repurchases of our Common Stock under the November 2000 Plan.

As of March 31, 2023, we had a total of approximately $19,325,000 of cancelable and non-cancelable capital expenditure commitments, principally for manufacturing and production equipment, which we intend to fund with existing cash, and approximately $2,083,000 of capital expenditure items which had been received and included in Property, plant and equipment in the accompanying Condensed Consolidated Balance Sheets, but not yet paid for. 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, including architectural and construction costs. We believe cash generated from operations together with our available cash and cash equivalents will be sufficient to fund planned operational needs, capital equipment purchases, and the planned construction, for both the short and long term.

We do not consider the impact of inflation or fluctuations in the exchange rates for foreign currency transactions to have been significant during the last three fiscal years.

Critical Accounting Policies and Estimates

There have been no material changes in our judgments and assumptions associated with the development of our critical accounting estimates during the period ended March 31, 2023. Refer to the section entitled “Critical Accounting Policies and Estimates” in Part II, Item 7 – “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

Item 3 — 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, our 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 March 31, 2023, our long-term investment portfolio, recorded on our Condensed 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 loss”, a component of 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 March 31, 2023.

Our exposure to market risk for fluctuations in foreign currency exchange rates relates 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. The functional currency of all other subsidiaries in Europe and other subsidiaries in Asia is the U.S. Dollar. While we believe the risk of fluctuations in foreign currency exchange rates for these subsidiaries is generally not significant, they can be subject to substantial currency changes, and therefore foreign exchange exposures.

Item 4 — Controls and Procedures

(a) Disclosure regarding controls and procedures.

As required by Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), management, with the participation of our Chief Executive Officer (“CEO”) (who is our principal executive officer) and Chief Financial Officer (“CFO”) (who is our principal financial officer), conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the last fiscal quarter (i.e., March 31, 2023). 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 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 information required to be disclosed by a company in the reports 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. Management recognizes any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2023, our CEO and CFO concluded, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

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. Accordingly, management, including the CEO and CFO, recognizes our disclosure controls or our internal control over financial reporting may not prevent or detect all errors and all fraud. The design of a control system must reflect the fact 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 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

-24-

Vicor Corporation

March 31, 2023

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 control’s 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.

(b) 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 March 31, 2023, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Long-Term Investments

3. Long-Term Investments

As of March 31, 2023 and December 31, 2022, the Company held one auction rate security with a par value of $3,000,000 and an estimated fair value of approximately $2,631,000 and $2,622,000, 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 March 31, 2023, 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. 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 March 31, 2023.

Fair Value Measurements

4. 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 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.

Assets and liabilities measured at fair value on a recurring basis included the following as of March 31, 2023 (in thousands):

	Using
	Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total Fair Value as of March 31, 2023

The change in the estimated fair value calculated for the investment valued on a recurring basis utilizing Level 3 inputs (i.e., the Failed Auction Security) for the three months ended March 31, 2023 was as follows (in thousands):

Balance at the beginning of the period	$	2,622
Credit gain on available-for-sale security included in Other income (expense), net		9
Balance at the end of the period	$	2,631

Management utilized a probability weighted discounted cash flow model to determine the estimated fair value as of March 31, 2023.

8. Income Taxes

The provision (benefit) for income taxes is based on the estimated annual effective tax rate for the year, which includes estimated federal, state and foreign income taxes on the Company’s projected pre-tax income.

The provision (benefit) for income taxes and the effective income tax rates were as follows (dollars in thousands):

	Three Months Ended March 31,
	2023			2022
Provision (benefit) for income taxes	$	1,141		$	(48	)
Effective income tax rate		9.2	%		(1.0	)%

The effective tax rates were lower than the statutory tax rates for the three months ended March 31, 2023 and 2022 primarily due to the Company’s full valuation allowance position against domestic deferred tax assets. The provision (benefit) for income taxes for the three months ended March 31, 2023 and 2022 included estimated federal, state and foreign income taxes in jurisdictions in which the Company does not have sufficient tax attributes.

As of March 31, 2023, the Company has a valuation allowance of approximately $47,413,000 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, the Company faces uncertainties in forecasting its operating results due to 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, as of March 31, 2023, it 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 March 31, 2023. 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 continue, and the Company’s concerns about industry uncertainty and world events, supply and factory 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. 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 Condensed Consolidated Statements of Operations, the effect of which would be an increase in reported net income.

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 IRS is in the process of closing examination of the 2019 tax year with no material adjustments. There are no other audits or examinations in process in any other jurisdiction.

Commitments and Contingencies

10. Commitments and Contingencies

At March 31, 2023, the Company had approximately $19,325,000 of cancelable and non-cancelable capital expenditure commitments, principally for manufacturing equipment, and approximately $2,083,000 of capital expenditure items which had been received and included in Property, plant and equipment in the accompanying Condensed 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 complaint, as amended, alleged that the Company’s unregulated bus converters used in intermediate bus architecture power supply systems infringed 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, and collectively the “SynQor Patents”). The Company asserted counterclaims against SynQor alleging unfair competition and tortious interference with business relations (the “Counterclaims”). As a result of certain actions by the United States Patent and Trademark Office (“USPTO”) and the District Court, SynQor’s infringement allegations regarding the ‘021 patent and the ‘290 patent were dismissed from the case prior to the beginning of trial. Specifically, the USPTO invalidated all the asserted claims of the ‘021 patent and that decision was upheld on appeal on August 30, 2017. In addition, on October 5, 2022, the District Court issued

an order involuntarily dismissing the ‘290 patent infringement allegations on grounds of equitable and judicial estoppel, in view of representations by SynQor to the District Court agreeing to such dismissal as a condition of lifting a prior stay of the lawsuit. On January 18, 2023, the United States Court of Appeals for the Federal Circuit issued a decision upholding a decision of the Patent Trial and Appeal Board of the USPTO invalidating all claims of the ‘290 patent.

A trial in the District Court began on October 17, 2022 on the asserted claims of the ‘190 patent and the ‘702 patent, as well as on the Company’s Counterclaims. The District Court dismissed the Company’s Counterclaims on October 25, 2022. On October 26, 2022, the jury returned a verdict on SynQor’s patent infringement claims, finding that the Company willfully infringed the ‘702 patent, but did not infringe the ‘190 patent. The jury awarded SynQor damages in the amount of $6,500,000 for infringement of the ‘702 patent. All of the SynQor Patents expired in 2018.

On December 23, 2022, SynQor filed in the District Court (a) a motion for judgment as a matter of law that the Company infringed the ‘190 patent, (b) a motion requesting the District Court to award SynQor treble damages, as well as pre- and post-judgment interest, (c) a motion requesting the District Court to award SynQor its attorneys’ fees, and (d) a motion for a new trial. On December 23, 2022, the Company filed in the District Court (a) a motion requesting judgment as a matter of law that it did not infringe the ‘702 patent, and (b) a motion requesting judgment with respect to its defenses of equitable estoppel and waiver. The Court has not yet acted on any of these motions. To the extent that the District Court ultimately rules against the Company with respect to any of the aforementioned motions, the Company anticipates appealing those rulings to the United States Court of Appeals for the Federal Circuit. The Company similarly anticipates appealing the District Court’s order dismissing the Company’s Counterclaims against SynQor.

In accordance with applicable accounting standards, the Company recorded a litigation related accrual of $6,500,000 in the third quarter of 2022 as its estimate based on the jury award, using estimated outcomes ranging from $0 to treble damages plus attorney fees.

In addition, the Company is involved in certain other litigation and claims incidental to the conduct of its business. While the outcome of such other lawsuits and claims against the Company cannot be predicted with certainty, management does not expect such litigation or claims will have a material adverse impact on the Company’s financial position or results of operations.
