(unaudited)

Basis of Presentation

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~~nine months ended ~~June~~September 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~~bu

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):

(unaudited)

As of ~~June~~September 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~~September 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~~long

-term as of ~~June~~

September 30, 2021.

Based on the fair value measurements described in Note 4, the fair value of the Failed Auction Security on ~~June~~September 30, 2021, with a par value of $3,000,000, was estimated by the Company to be approximately ~~$2,561,000.~~$2,598,000. The gross unrealized loss of ~~$439,000~~$402,000 on the Failed Auction Security consists of two types of estimated loss: an aggregate credit loss of ~~$31,000~~$30,000 and an aggregate temporary impairment of ~~$408,000.~~$372,000. 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.

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.

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 ~~June~~September 30, 2021 (in thousands):

As of ~~June~~September 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~~September 30, 2021. The major assumptions used in preparing the DCF model were similar to those described in

Note 5—5 - Fair Value

Measurements in the Notes to the Consolidated Financial Statements contained in the Company’s 2020 Form

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

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~~

The effective tax rates were lower than the statutory tax ~~rates~~r

tes for the three and ~~six~~nine months ended ~~June~~September 30, 2021 and 2020 primarily due to the Company’s full valuation allowance position against domestic deferred tax ~~assets.~~assets and excess tax benefits related to stock based compensation during those periods. The (benefit) provision ~~(benefit)~~ for income taxes for the three and ~~six~~nine months ended ~~June~~September 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~~September 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~~September 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~~September 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.

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. There are no other audits or examinations in process in any other jurisdiction.

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~~

“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 June 29, 2021,August 30, 2017, 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~~final decision finding all of the ~~challenged~~asserted claims of the ‘702 patent ~~were~~to be 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.

‘290 patent: On June 16, 2021, the PTAB issued a decision ~~affirming the examiner’s rejection of~~finding all of the claims of the ‘290 ~~patent.~~patent unpatentable. SynQor has filed an appeal of that decision to the Federal Circuit, where it remains pending.

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

As noted above, the IPRx’s relating to the asserted claims of the ‘190 and ‘290 patents remain pending or on appeal. In addition, SynQor attempted to add new claims during the IPRx of the ‘021 patent. Those claims were rejected by the PTAB. SynQor subsequently filed an appeal with the Federal Circuit seeking to vacate that rejection as moot, in view of the expiry of the term of the ‘021 patent, and that appeal remains pending.

~~(unaudited)~~

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.

Management’s Discussion and Analysis of

Financial Condition and Results of Operation

~~June~~September 30, 2021

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~~We have taken steps to address certain supply chain risks, and we believe our actions have mitigated those risks ~~particularly for the second half of 2020;~~to date; however, there are no assurances that those steps will continue to mitigate risks infor the remainder of 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~~Third Quarter 2021 Financial Performance Compared to ~~First~~Second Quarter 2021 Financial Performance

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

Net revenues ~~increased 7.4%~~decreased 11.0% to $84,911,000 for the third quarter of 2021, from $95,376,000 for the second quarter of ~~2021, from $88,796,000~~2021. Net revenues for ~~the first quarter of 2021, as total bookings for the quarter increased 51.0% as compared to the first quarter of 2021,~~Brick Products decreased 23.7%, primarily due to ~~a 99.3% increase~~market conditions in ~~Advanced Products bookings in the second quarter of 2021 compared to the first quarter of 2021.~~Europe and Asia Pacific. Advanced Products revenue rose ~~19.7%~~6.0% sequentially compared to the ~~first~~second 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%~~62.4% of total net revenues in the ~~second~~third quarter of 2021 as compared to ~~69.4%~~64.3% in the ~~first~~second quarter of 2021.

Gross margin ~~increased~~decreased to $42,813,000 for the third quarter of 2021 from $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~~decreased to 50.4% for the third quarter of 2021 from 52.3% for the second quarter of ~~2021 from 50.3% for the first quarter of~~ 2021. Both the ~~increase~~decrease in gross margin dollars and the ~~increased~~decreased gross margin percentage were primarily due to the ~~increase~~decrease in net revenues ~~an improved product mix, a reduction in cost variances~~ and ~~process yield improvements.~~lower absorption of overhead expenses.

Backlog, which represents the total value of orders for products for which shipment is scheduled within the next 12 months, was approximately $295,695,000 at the end of the third quarter of 2021, as compared to $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.~~

~~June~~September 30, 2021

Operating expenses for the third quarter of 2021 increased $979,000, or 3.3%, to $30,841,000 from $29,862,000 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,~~2021. Selling, general, and administrative expenses ~~of $365,000,~~increased approximately $733,000, primarily due to increases in compensation, outside services, legal fees and sales commissions. Research and development expenses increased approximately $246,000, primarily due to an increase in compensation expense, partially offset by ~~an increase~~a decrease in ~~research~~project and ~~development expenses of $247,000.~~pre-production materials.

We reported net income for the ~~second~~third quarter of 2021 of ~~$19,394,000,~~$13,259,000, or ~~$0.43~~$0.29 per diluted share, compared to net income of ~~$15,092,000~~$19,394,000 or ~~$0.34~~$0.43 per diluted share, for the ~~first~~second quarter of 2021.

For the ~~second~~third quarter of 2021, depreciation and amortization totaled ~~$2,812,000,~~$2,946,000 and capital additions totaled ~~$14,994,000,~~$15,160,000 as compared to depreciation and amortization of ~~$2,806,000~~$2,812,000 and ~~$9,264,000~~$6,518,000 of capital additions for the ~~first~~second quarter of 2021.

Inventories increased by approximately ~~$2,873,000,~~$6,280,000, or ~~5.3%~~11.0%, to $63,409,000 at September 30, 2021, compared to $57,129,000 at June 30, 2021, ~~compared~~primarily with raw materials, due to ~~$54,256,000 at March 31, 2021.~~the revenue in the third quarter of 2021 falling below expectations, primarily caused by component and capacity issues which contributed to production delays.

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

Net revenues for the ~~second~~third quarter of 2021 were ~~$95,376,000,~~$84,911,000, an increase of ~~$24,615,000,~~$6,799,000, or ~~34.8%~~8.7%, as compared to ~~$70,761,000~~$78,112,000 for the ~~second~~third quarter of 2020. Net revenues, by product line, for the three months ended ~~June~~September 30, 2021 and 2020 were as follows (dollars in thousands):


					Increase

The increase in net revenues for Advanced Products was primarily the result of growth in the data center and high performance computing business, ~~while~~primarily in the United States and Asia Pacific markets. The decrease in net revenues for Brick Products ~~increase~~ was primarily due to ~~continued favorable~~unfavorable market ~~conditions. The increases in net revenues for both product lines are also reflected~~conditions in the ~~bookings patterns of~~Asia Pacific markets, offset by increases from customers in 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~~United States 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.Europe.

Gross margin for the ~~second~~third quarter of 2021 increased ~~$19,553,000,~~$9,466,000, or ~~64.5%~~28.4%, to ~~$49,871,000,~~$42,813,000, from ~~$30,318,000~~$33,347,000 for the ~~second~~third quarter of 2020.

Our exposure to market risk fluctuations in foreign currency exchange rates relates to the operations of Vicor Japan Company, Ltd.

~~June~~September 30, 2021

Income before income taxes was $12,366,000 for the third quarter of 2021, as compared to $6,437,000 for the third quarter of 2020.

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

(Benefit) provision for income taxes							$	(886	)	$	651
Effective income tax rate		4.9	%		(17.9	)%		(7.2	)%		10.1	%

The effective tax rates were lower than the statutory tax rates for the three months ended ~~June~~September 30, 2021 and 2020 primarily due to the Company’s full valuation allowance position against domestic deferred tax ~~assets.~~assets and excess tax benefits related to stock based compensation during those periods. The (benefit) provision ~~(benefit)~~ for income taxes for the three months ended ~~June~~September 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~~third quarter of 2021 of ~~$19,394,000,~~$13,259,000, or ~~$0.43~~$0.29 per diluted share, compared to ~~$2,667,000,~~$5,785,000, or ~~$0.06~~$0.13 per diluted share, for the ~~second~~third quarter of 2020.

The increase in net revenues for Advanced Products was primarily the result of growth in the data center and high performance computing business, in the United States and Asia Pacific markets. The increase in net revenues for Brick Products was primarily due to increases from customers in the United States and Europe, offset by a decrease in net revenues from customers in the European markets. The increases in net revenues for both Brick Products and Advanced Products were ~~principally due to~~also the result of increases in new orders for Advanced Products ~~of 126.9%~~ and Brick Products ~~of 13.9%~~ for the ~~six~~nine months ended ~~June~~September 30, 2021 compared to the ~~six~~nine months ended ~~June~~September 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.

~~Management’s Discussion and Analysis of~~

~~Financial Condition and Results of Operation~~

~~June 30, 2021~~

The primary sources of cash for the ~~six~~nine months ended ~~June~~September 30, 2021 were ~~$30,115,000 of cash generated through operating activities, $30,000,000~~$50,000,000 from the sale or maturities of short-term investments, $40,227,000 of cash generated from operations, and ~~$4,751,000~~$8,621,000 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~~nine months ended ~~June~~September 30, 2021 were $50,706,000 for the purchases of short-term investments and ~~$15,782,000~~$30,942,000 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~~nine months ended ~~June~~September 30, 2021. As of ~~June~~September 30, 2021, we had approximately $8,541,000 remaining available for repurchases of our Common Stock under the November 2000 Plan.

As of ~~June~~September 30, 2021, we had approximately ~~$21,524,000~~$22,046,000 of capital expenditure commitments, principally for manufacturing equipment, which we intend to fund with existing cash, and approximately ~~$8,476,000~~$6,607,000 of capital ~~expenditures~~expenditure items which ~~have~~had been received and ~~reflected~~included in Property, plant and equipment in the accompanying Condensed Consolidated Balance Sheets, but not yet paid for. In addition to these commitments, we ~~had,~~have, in aggregate, approximately ~~$28,000,000~~$20,000,000 of remaining budgeted capital expenditures ~~in 2021~~expected to be incurred through the first half of 2022 associated with the construction of a 90,000 sq. ft. addition to the Company’s existing manufacturing facility and the installation of new production equipment. 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~~September 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~~September 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)~~

(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~~September 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~~September 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

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.
