VICOR CORPORATION

Notes to Condensed Consolidated Financial Statements

June 30, 2021

(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 and six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for any other interim period or the year ending December 31, 2021. The balance sheet at December 31, 2020 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, 2020 filed by the Company with the SEC on March 1, 2021 (“2020 Form 10-K”).

2.	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, handling and customs (e.g., tariff) costs incurred in connection with the sale of products are included in cost of revenues.

Inventory that is 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 expectation 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.

Inventories were as follows (in thousands):

	June 30, 2021		December 31, 2020
Raw materials	$	42,530	$	42,556
Work-in-process		10,101		7,424
Finished goods		4,498		7,289
	$	57,129	$	57,269
3.	Short-Term and Long-Term Investments
---	---

As of June 30, 2021, the Company held $70,469,000 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 June 30, 2021 and December 31, 2020, the Company held one 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. 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 June 30, 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. 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 June 30, 2021.

Based on the fair value measurements described in Note 4, the fair value of the Failed Auction Security on June 30, 2021, with a par value of $3,000,000, was estimated by the Company to be approximately $2,561,000. The gross unrealized loss of $439,000 on the Failed Auction Security consists of two types of estimated loss: an aggregate credit loss of $31,000 and an aggregate temporary impairment of $408,000. In determining the amount of credit loss, the Company compared 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 as significant inputs, among other factors.

The following table represents a rollforward of the activity related to the credit loss recognized in earnings on the Failed Auction Security for the six months ended June 30 (in thousands):

	2021			2020
Balance at the beginning of the period	$	33		$	37
Reductions in the amount related to credit gain for which other-than- temporary impairment was not previously recognized		(2	)		(2	)
Balance at the end of the period	$	31		$	35

At this time, the Company has no intent to sell the impaired Failed Auction Security and does not believe it is more likely than not the Company will be required to sell this 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 Condensed Consolidated Statements of Operations, and any such impairment adjustments may be material.

Based on the Company’s ability to access cash and cash equivalents, its short-term investments and its expected operating cash flows, management does not anticipate the current lack of liquidity associated with the Failed Auction Security held will affect the Company’s ability to execute its current operating plan.

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 June 30, 2021 (in thousands):

As of June 30, 2021, there was insufficient observable auction rate security market information available to determine the fair value of the Failed Auction Security using Level 1 or Level 2 inputs. As such, the Company’s investment in the Failed Auction Security was deemed to require valuation using Level 3 inputs. Management, after consulting with advisors, valued the Failed Auction Security using analyses and pricing models similar to those used by market participants (i.e., buyers, sellers, and the broker-dealers responsible for execution of the Dutch auction pricing mechanism by which each issue’s interest rate was set). Management utilized a probability weighted discounted cash flow (“DCF”) model to determine the estimated fair value of this security as of June 30, 2021. The major assumptions used in preparing the DCF model were similar to those described in Note 5—Fair Value Measurements in the Notes to the Consolidated Financial Statements contained in the Company’s 2020 Form 10-K.

Quantitative information about Level 3 fair value measurements as of June 30, 2021 is as follows (dollars in thousands):

	Fair Value		Valuation<br> Technique	Unobservable<br> <br>Input
Failed Auction Security	$	2,561	Discounted cash flow	Cumulative probability of earning the maximum rate until maturity	0.15	%
				Cumulative probability of principal return prior to maturity	94.27	%
				Cumulative probability of default	5.58	%
				Liquidity risk premium	5.00	%
				Recovery rate in default	40.00	%

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 six months ended June 30, 2021 was as follows (in thousands):

Balance at the beginning of the period	$	2,517
Credit gain on <br>available-for-sale<br> security included in Other income (expense), net		2
Gain included in Other comprehensive income		42
Balance at the end of the period	$	2,561

The Company has classified its contingent consideration obligations as Level 3 because the fair value for these liabilities was determined using unobservable inputs. The liabilities were based on estimated sales of legacy products over the period of royalty payments at the royalty rate, discounted using the Company’s estimated cost of capital.

The change in the estimated fair value c alculated for the liabilities valued on a recurring basis utilizing Level 3 inputs

(i.e., the Contingent consideration obligations) for the six months ended June 30, 2021 was as follows (in thousands):

The increase in accounts receivable was primarily due to an increase in net revenues of approximately $15,381,000 in May-June 2021 compared to November-December 2020. The decrease in short-term deferred revenue and customer prepayments was primarily due to the recognition of the associated revenue in the second quarter of 2021, as noted below. The increase in sales allowances was primarily due to the increase in the net revenues for the six months ended June 30, 2021.

Deferred expenses are included in Other current assets in the accompanying Condensed Consolidated Balance Sheets.

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. The Company recognized revenue of approximately $2,410,000 and $3,081,000 for the three and six months ended June 30, 2021, respectively, and $1,700,000 and $1,736,000 for the three and six months ended June 30, 2020, respectively, that was included in deferred revenue at the beginning of each respective period.

6.	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 t heir

grant date. Stock-based compensation expense was as follows (in thousands):

	Three Months Ended<br> June 30,				Six Months Ended<br> June 30,
	2021		2020		2021		2020
Cost of revenues	$	252	$	277	$	480	$	396
Selling, general and administrative		779		1,030		1,632		1,467
Research and development		536		629		1,026		783
Total stock-based compensation	$	1,567	$	1,936	$	3,138	$	2,646

Compensation expense by type of award was as follows (in thousands):

	Three Months Ended<br> June 30,				Six Months Ended<br> June 30,
	2021		2020		2021		2020
Stock options	$	1,336	$	1,737	$	2,667	$	2,243
ESPP		231		199		471		403
Total stock-based compensation	$	1,567	$	1,936	$	3,138	$	2,646

The increase in stock option compensation expense for the six months ended June 30, 2021 compared to the six months ended June 30, 2020, was primarily due to an increase in the number of stock options granted and higher stock-based compensation expense associated with June 2020 stock option awards.

7.	Rental Income

Income, net under the Company’s operating lease agreement, for its owned facility leased to a third party in California, was approximately $198,000 and $396,000 for the three and six months ended June 30, 2021 and 2020, respectively.

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<br> June 30,						Six Months Ended<br> June 30,
	2021			2020			2021			2020
Provision (benefit) for income taxes	$	999		$	(406	)	$	856		$	(900	)
Effective income tax rate		4.9	%		(17.9	)%		2.4	%		(2,195.1	)%

The effective tax rates were lower than the statutory tax rates for the three and six months ended June 30, 2021 and 2020 primarily due to the Company’s full valuation allowance position against domestic deferred tax assets. The provision (benefit) for income taxes for the three and six months ended June 30, 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.

As of June 30, 2021, the Company had a valuation allowance of approximately $37,856,000 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. While recent positive operating results, as a result of increases in bookings, caused the Company to be in a cumulative income position as of June 30, 2021, the Company faces uncertainties in forecasting its operating results due to continued negative impacts on the Company’s supply chain, 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, 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 was still warranted as of June 30, 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 quarterly earnings and increases in bookings continue, and the Company’s concerns about industry uncertainty and world events, including continued negative impacts on the Company’s supply chain, 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. However, the valuation allowance against certain state tax credits will likely never be released due to uncertainty on the utilization of these credits. 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.

10.	Commitments and Contingencies
---	---

At June 30, 2021, the Company had approximately $21,524,000 of capital expenditure commitments, principally for manufacturing equipment, and approximately

$8,476,000 of capital expenditures items which have been received and reflected in the accompanying Condensed Consolidated Balance Sheets, but not yet paid for. In addition to these commitments, the Company had, in the aggregate, approximately $28,000,000 of remaining budgeted capital expenditures in 2021 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.

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 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 May 23, 2016, after extensive discovery, the Texas Action was stayed by the court pending completion of certain inter partes reexamination (“IPRx”) proceedings at the United States Patent and Trademark Office (“USPTO”) (including any appeals from such proceedings to the Federal Circuit (as defined below)) concerning the SynQor patents, which are described below. That stay remains in force. On March 17, 2021, SynQor filed a motion to lift the stay in the Texas Action. The Company has opposed that motion, which remains pending.

In 2011, in response to the filing of the Texas Action, the Company initiated IPRx proceedings at the USPTO challenging the validity of all claims that were asserted against the Company by SynQor. The current status of these proceedings is as follows. Regarding the ‘190 patent IPRx, the United States Court of Appeals for the Federal Circuit (the “Federal Circuit”) issued a decision on March 13, 2015, determining that certain claims were invalid and remanding the matter to the Patent Trial and Appeal Board (“PTAB”) of the USPTO for further proceedings. On February 20, 2019, the PTAB 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. 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.

On August 30, 2017, the Federal Circuit issued rulings with regard to the IPRx proceedings for the ’021, ‘702 and ‘290 patents. With respect to the ‘021 patent, the Federal Circuit affirmed the PTAB’s determination that all of the challenged claims of the ‘021 patent were invalid. The Federal Circuit remanded the case to the PTAB for further consideration of the patentability of certain claims that had been added by amendment during the reexamination. On February 20, 2019, the PTAB issued a decision affirming the examiner’s rejections of all challenged claims. SynQor has filed an appeal of that decision in the Federal Circuit. That appeal has been stayed pending resolution of the pending appeal regarding the ‘190 patent IPRx. On June 29, 2021, the Federal Circuit issued an order lifting the stay and setting a briefing scheduling for the appeal.

With respect to the ‘702 patent, the Federal Circuit affirmed the PTAB’s determination that all of the challenged claims of the ‘702 patent were patentable. With respect to the ‘290 patent, the Federal Circuit vacated the PTAB’s decision upholding the patentability of the ‘290 patent claims, and remanded the case to the PTAB for further consideration. On February 20, 2019, the PTAB issued a decision reversing its prior affirmance of the examiner’s non-adoption of rejections with respect to the ‘290 patent, and entering rejections of all of the claims of the ‘290 patent. On May 20, 2019, as permitted by USPTO rules, SynQor requested the USPTO to reopen prosecution of this proceeding to address the new rejections made by the PTAB. On September 28, 2020, the examiner issued a decision reaffirming the PTAB’s rejection of all of the claims of the ‘290 patent. On March 18, 2021, SynQor appealed this decision to the PTAB. On June 16, 2021, the PTAB issued a decision affirming the examiner’s rejection of all of the claims of the ‘290 patent.

On October 31, 2017, the Company filed a request with the USPTO for ex parte reexamination (“EPRx”) of the asserted claims of the ‘702 patent, based on different prior art references than had been at issue in the previous IPRx of the ‘702 patent. On August 6, 2018, the Company filed a similar request with the USPTO for EPRx of the asserted claims of the ‘190 patent, based on different prior art references than had been at issue in the previous IPRx of the ‘190 patent. On December 18, 2020, the PTAB issued rulings upholding the validity of the asserted claims in the EPRx proceedings for both the ‘702 and ‘190 patents. Accordingly, both of those proceedings are now terminated.

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 reexamination proceedings will have no effective term and cannot be the basis for any liability by the Company.

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 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.

11.	Impact of Recently Issued Accounting Standards

In December 2019, the Financial Accounting Standards Board (“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 June 30, 2021 are not expected to have a material impact on the Company’s consolidated financial statements.

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. 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 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 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. During 2020, we took steps to address certain supply chain risks, and we believe our actions mitigated those risks, particularly for the second half of 2020; however, there are no assurances that those steps will continue to mitigate risks in 2021 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 and/or increase again. 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 Second Quarter 2021 Financial Performance Compared to First Quarter 2021 Financial Performance

The following summarizes our financial performance for the second quarter of 2021, compared to the first quarter of 2021:

•	Net revenues increased 7.4% to $95,376,000 for the second quarter of 2021, from $88,796,000 for the first quarter of 2021, as total bookings for the quarter increased 51.0% as compared to the first quarter of 2021, primarily due to a 99.3% increase in Advanced Products bookings in the second quarter of 2021 compared to the first quarter of 2021. Advanced Products revenue rose 19.7% sequentially compared to the first quarter of 2021. This growth, though, continued to be constrained by limited component availability due to global semiconductor supply allocation issues experienced during the quarter, along with certain internal processing and testing constraints.
•	Export sales represented approximately 64.3% of total net revenues in the second quarter of 2021 as compared to 69.4% in the first quarter of 2021.
---	---
•	Gross margin increased to $49,871,000 for the second quarter of 2021 from $44,700,000 for the first quarter of 2021, and gross margin, as a percentage of net revenues, increased to 52.3% for the second quarter of 2021 from 50.3% for the first quarter of 2021. Both the increase in gross margin dollars and the increased gross margin percentage were primarily due to the increase in net revenues, an improved product mix, a reduction in cost variances and process yield improvements.
---	---
•	Backlog, which represents the total value of orders for products for which shipment is scheduled within the next 12 months, was approximately $210,565,000 at the end of the second quarter of 2021, as compared to $157,134,000 at the end of the first quarter of 2021. The increase in backlog was primarily due to the increased bookings, discussed above.

•	Operating expenses for the second quarter of 2021 decreased $118,000, or 0.4%, to $29,862,000 from $29,980,000 for the first quarter of 2021, due to a decrease in selling, general, and administrative expenses of $365,000, partially offset by an increase in research and development expenses of $247,000.
•	We reported net income for the second quarter of 2021 of $19,394,000, or $0.43 per diluted share, compared to net income of $15,092,000 or $0.34 per diluted share, for the first quarter of 2021.
---	---
•	For the second quarter of 2021, depreciation and amortization totaled $2,812,000, and capital additions totaled $14,994,000, as compared to depreciation and amortization of $2,806,000 and $9,264,000 of capital additions, for the first quarter of 2021.
---	---
•	Inventories increased by approximately $2,873,000, or 5.3%, to $57,129,000 at June 30, 2021, compared to $54,256,000 at March 31, 2021.
---	---

Three Months Ended June 30, 2021 Compared to Three Months Ended June 30, 2020

Net revenues for the second quarter of 2021 were $95,376,000, an increase of $24,615,000, or 34.8%, as compared to $70,761,000 for the second quarter of 2020. Net revenues, by product line, for the three months ended June 30, 2021 and 2020 were as follows (dollars in thousands):


	2021		2020		%
Brick Products	$	54,352	$	46,428		17.1	%
Advanced Products		41,024		24,333		68.6	%
Total	$	95,376	$	70,761		34.8	%

All values are in US Dollars.

The increase in net revenues for Advanced Products was primarily the result of growth in the data center and high performance computing business, while the Brick Products increase was primarily due to continued favorable market conditions. The increases in net revenues for both product lines are also reflected in the bookings patterns of the second quarter of 2021. Total bookings for the second quarter of 2021 increased 70.8% from the second quarter of 2020, primarily due to an increase of Advanced Products and Brick Products bookings of 181.6% and 4.6%, respectively. The increase in bookings largely reflected our customers’ response to the 20% to 30% increase in lead-times for our Brick Products and Advanced Products, respectively, plus growth in our data center business, for Advanced Products.

Gross margin for the second quarter of 2021 increased $19,553,000, or 64.5%, to $49,871,000, from $30,318,000 for the second quarter of 2020. Gross margin, as a percentage of net revenues, increased to 52.3% for the second quarter of 2021, compared to 42.8% for the second quarter of 2020. The increase in gross margin dollars and gross margin percentage was primarily due to the increase in net revenues, an improved product mix and process yield improvements.

The provision (benefit) for income taxes and the effective income tax rates for the three months ended June 30, 2021 and 2020 were as follows (dollars in thousands):

	2021			2020
Provision (benefit) for income taxes	$	999		$	(406	)
Effective income tax rate		4.9	%		(17.9	)%

The effective tax rates were lower than the statutory tax rates for the three months ended June 30, 2021 and 2020 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 June 30, 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 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 second quarter of 2021 of $19,394,000, or $0.43 per diluted share, compared to $2,667,000, or $0.06 per diluted share, for the second quarter of 2020.

Six Months Ended June 30, 2021 Compared to Six Months Ended June 30, 2020

Net revenues for the six

months ended June 30, 2021 were $184,172,000, an increase of $50,010,000, or 37.3%, from $134,162,000 for the six months ended June 30, 2020. Net revenues, by product line, for the six months ended June 30, 2021 and the six months ended June 30, 2020 were as follows (dollars in thousands):


	2021		2020		%
Brick Products	$	108,811	$	91,945		18.3	%
Advanced Products		75,361		42,217		78.5	%
Total	$	184,172	$	134,162		37.3	%

All values are in US Dollars.

The increases in net revenues for Brick Products and Advanced Products were principally due to increases in new orders for Advanced Products of 126.9% and Brick Products of 13.9% for the six months ended June 30, 2021 compared to the six months ended June 30, 2020. The increase in bookings largely reflected our customers’ response to the 20% to 30% increase in lead-times for our Brick Products and Advanced Products, respectively, plus growth in our data center business, for Advanced Products.

Gross margin for the six months ended June 30, 2021 increased $36,922,000, or 64.0%, to $94,571,000 from $57,649,000 for the six months ended June 30, 2020. Gross margin, as a percentage of net revenues, increased to 51.3% for the six month period ended June 30, 2021, as compared to 43.0% for the six month period ended June 30, 2020. The increase in gross margin dollars and gross margin percentage was primarily due to the increase in net revenues, an improved product mix, process yield improvements and lower tariff charges.

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 other subsidiaries in Europe and Asia have experienced more unfavorable foreign currency exchange rate fluctuations in 2021 compared to 2020. Interest income increased due to an increase in interest bearing investments in 2021 compared to 2020, due to the net proceeds of approximately $109.7 million from our underwritten public offering of our Common Stock completed in June 2020.

Income before income taxes was $35,334,000 for the six months ended June 30, 2021, as compared to $41,000 for the six months ended June 30, 2020.

Management’s Discussion and Analysis of

Financial Condition and Results of Operation

June 30, 2021

The provision (benefit) for income taxes and the effective income tax rates for the six months ended June 30, 2021 and 2020 were as follows (dollars in thousands):

	2021			2020
Provision (benefit) for income taxes	$	856		$	(900	)
Effective income tax rate		2.4	%		(2,195.1	)%

The effective tax rates were lower than the statutory tax rates for the six months ended June 30, 2021 and 2020 primarily due to the Company’s full valuation allowance position against domestic deferred tax assets. The provision (benefit) for income taxes for the six months ended June 30, 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.

We reported net income for the six months ended June 30, 2021 of $34,486,000, or $0.77 per diluted share, as compared to $932,000, or $0.02 per diluted share, for the six months ended June 30, 2020.

Liquidity and Capital Resources

As of June 30, 2021, we had $159,763,000 in cash and cash equivalents and $70,469,000 of highly liquid short-term investments. The ratio of total current assets to total current liabilities was 7.0:1 as of June 30, 2021 and 7.8:1 as of December 31, 2020. Working capital, defined as total current assets less total current liabilities, increased $22,834,000 to $299,253,000 as of June 30, 2021 from $276,419,000 as of December 31, 2020.

The changes in working capital from December 31, 2020 to June 30, 2021 were as follows (in thousands):

Management’s Discussion and Analysis of

Financial Condition and Results of Operation

June 30, 2021

The primary sources of cash for the six months ended June 30, 2021 were $30,115,000 of cash generated through operating activities, $30,000,000 from the sale or maturities of short-term investments and $4,751,000 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 six months ended June 30, 2021 were $50,706,000 for the purchases of short-term investments and $15,782,000 for the purchase of property and equipment.

In November 2000, our Board of Directors authorized the repurchase of up to $30,000,000 of 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 six months ended June 30, 2021. As of June 30, 2021, we had approximately $8,541,000 remaining available for repurchases of our Common Stock under the November 2000 Plan.

As of June 30, 2021, we had approximately $21,524,000 of capital expenditure commitments, principally for manufacturing equipment, which we intend to fund with existing cash, and approximately $8,476,000 of capital expenditures items which have been received and reflected in the accompanying Condensed Consolidated Balance Sheets, but not yet paid for. In addition to these commitments, we had, in aggregate, approximately $28,000,000 of remaining budgeted capital expenditures in 2021 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. Our primary needs for liquidity are for making continuing investments in manufacturing equipment and for funding the construction of the additional manufacturing space adjoining our existing Andover manufacturing facility, noted 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.

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 June 30, 2021, our long-term investment portfolio, recorded on our Condensed Consolidated Balance Sheet as “Long-term investments, 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 June 30, 2021.

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., June 30, 2021). 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 June 30, 2021, 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

-32-

Vicor Corporation

June 30, 2021

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 June 30, 2021, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
