Notes to Condensed Consolidated Financial Statements

June 30, 2024

(unaudited)

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, 2024 are not necessarily indicative of the results that may be expected for any other interim period or the year ending December 31, 2024. The balance sheet at December 31, 2023 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, 2023 filed by the Company with the SEC on February 28, 2024.

Long-Term Investments

As of June 30, 2024 and December 31, 2023, the Company held one auction rate security with a par value of $3,000,000 and an estimated fair value of approximately $2,600,000 and $2,530,000, respectively, purchased through and held in custody by a broker-dealer affiliate of Bank of America, N.A., that has experienced failed auctions (the “Failed Auction Security”) since February 2008. The Failed Auction Security held by the Company is Aaa/AA+ rated by major credit rating agencies, is collateralized by student loans, and is guaranteed by the U.S. Department of Education under the Federal Family Education Loan Program. Management is not aware of any reason to believe the issuer of the Failed Auction Security is presently at risk of default. Through June 30, 2024, 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, 2024. -7-

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, 2024 (in thousands):

Stock-Based Compensation

The Company uses the Black-Scholes option pricing model to calculate the fair value of stock option awards, whether they possess time-based vesting provisions or performance-based vesting provisions, and awards granted under the Vicor Corporation 2017 Employee Stock Purchase Plan (“ESPP”), as of their grant date.

Rental Income

Income, net under the Company’s operating lease agreement, for its owned facility leased to a third party in California, was approximately $227,000 and $198,000 for the three month periods ended June 30, 2024 and 2023, respectively, and $424,000 and $396,000 for the six month periods ended June 30, 2024 and 2023, respectively. The initial term of the lease agreement expired on May 31, 2024 and was extended for an additional eighty-four (84) months, commencing June 1, 2024 and ending May 31, 2031.

Income Taxes

The provision 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 (loss).

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

	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2024			2023			2024			2023
Provision for income taxes	$	4,216		$	2,537		$	5,287		$	3,678
Effective income tax rate		139.6	%		12.9	%		(51.0	)%		11.5	%

The effective tax rates differ from the statutory tax rates for the three and six months ended June 30, 2024 and 2023 primarily due to the Company’s full valuation allowance position against domestic deferred tax assets. The provision for income taxes for the three and six months ended June 30, 2024 and 2023 included estimated federal, state and foreign income taxes in jurisdictions in which the Company does not have sufficient tax attributes.

expense. This is further compounded by the Company not getting a deferred tax benefit from temporary differences due to the full valuation allowance on domestic deferred tax assets.

As of June 30, 2024, the Company had a valuation allowance of approximately $52,291,000 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. The Company faces uncertainties in forecasting its operating results due to supply and factory capacity constraints, certain process issues with the production of Advanced Products and the unpredictability in certain markets. This operating uncertainty also makes it difficult to predict the availability and utilization of tax benefits over the next several years. As a result, management has concluded, as of June 30, 2024, it is more likely than not the Company’s net domestic deferred tax assets will not be realized, and a full valuation allowance against all net domestic deferred tax assets is still warranted as of June 30, 2024. 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 Company’s concerns about industry uncertainty and world events, supply and factory capacity constraints, and process issues with the production of Advanced Products are resolved, and the amount of tax benefits the Company is able to utilize to the point that the Company believes future taxable income can be more reliably forecasted, the Company may release all or a portion of the valuation allowance in the near-term. If and when the Company determines the valuation allowance should be released (i.e., reduced), the adjustment would result in a tax benefit reported in that period’s Condensed Consolidated Statements of Operations, the effect of which would be an increase in reported net income.

The Company was informed in September 2021 by the Internal Revenue Service of their intention to examine the Company’s 2019 Federal income tax return. The IRS has closed examination of the 2019 tax year with no material adjustments. There are no other audits or examinations in process in any other jurisdiction.

shares of Common Stock for the three and six months ended June 30, 2023, respectively, were not included in the calculation of net income per share as the effect would have been antidilutive.

Commitments and Contingencies

At June 30, 2024, the Company had approximately $14,986,000 of cancelable and non-cancelable capital expenditure commitments, principally for manufacturing equipment.

As previously reported in its Quarterly Reports on Form 10-Q and Annual Reports on Form 10-K, 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 “District Court”). SynQor alleged that certain Vicor products infringed certain United States Patents owned by SynQor.

On October 26, 2022, after a trial in the District Court, the jury returned a verdict finding that the Company willfully infringed one SynQor patent, and awarding SynQor damages in the amount of $6,500,000.

On May 20, 2024, the District Court issued an Amended Corrected Final Judgment, awarding SynQor actual damages of $6,500,000, enhanced damages of $4,500,000, costs in the amount of approximately $87,000, attorney fees in the amount of $9,500,000, and pre-judgment interest of approximately $5,400,000, for a total judgment of approximately $26,000,000. In addition, the Court ordered that post-judgment interest would accrue at an amount of $2,323 per day starting on April 24, 2024 until the judgment is paid, compounded annually, and that additional post-judgment interest in the amount of $1,351 per day would accrue starting on May 20, 2024 until the judgment is paid, compounded annually.

On May 22, 2024, the Company filed an appeal of the District Court’s judgment to the United States Court of Appeals for the Federal Circuit. That appeal remains pending.

In accordance with applicable accounting standards, the Company recorded a litigation related accrual of $6,500,000 in the third quarter of 2022 and incremental litigation related accruals of $17,200,000 in the first quarter of 2024 and $2,300,000 in the second quarter of 2024 when the Amended Corrected Final Judgment was issued, for a total of $26,000,000, as its estimate based on the awarded judgments, including enhanced damages, pre-judgment interest, costs and attorney fees. The final determination of the litigation related accrual amount will be subject to appeal and could differ from the recorded liability.

Consistent with the court order, post-judgment interest will accrue on the pre-judgment amount until paid and the Company has recorded post judgment interest of approximately $212,000 in the second quarter of 2024 within the Selling, general and administrative expenses on the Statement of Operations and the associated Accrued litigation account.

On July 11, 2024, purported stockholders of the Company filed a putative class action lawsuit in the U.S. District Court for the Northern District of California against the Company and the Company’s Chief Executive Officer, President and Chairman. On July 25, 2024, a purported stockholder of the Company filed a putative class action lawsuit in the U.S. District Court for the District of Massachusetts against the Company; the Company’s Chief Executive Officer, President and Chairman; the Company’s Chief Financial Officer, Treasurer, Secretary and Director; and the Company’s Vice President of Global Sales and Marketing and Director. The plaintiffs allege violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), due to allegedly false and misleading statements during earnings calls in 2023 about the Company’s commercial relationship with an existing customer. The complaints seek damages, interest and attorneys’ fees and costs. The plaintiffs are in the process of serving their complaints, and no substantive proceedings have taken place. The Company believes the plaintiffs’ claims are without merit and intends to vigorously defend against the lawsuits.

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

Impact of Recently Issued Accounting Standards

On November 27, 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which enhances segment disclosures and requires additional disclosures of segment expenses. This ASU is effective for annual periods in fiscal years beginning after December 15, 2023, and interim periods thereafter. Early adoption is permitted. The Company expects this ASU to impact disclosures with no impact to the Company’s consolidated financial statements.

In December 2023, FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which focuses on the rate reconciliation and income taxes paid. ASU No. 2023-09 requires a public business entity (PBE) to disclose, on an annual basis, a tabular rate reconciliation using both percentages and currency amounts, broken out into specified categories with certain reconciling items further broken out by nature and jurisdiction to the extent those items exceed a specified threshold. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by federal, state/local, and foreign and by jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. For PBEs, the new standard is effective for annual periods beginning after December 15, 2024, with early adoption permitted. An entity may apply the amendments in this ASU prospectively by providing the revised disclosures for the period ending December 31, 2025 and continuing to provide the pre-ASU disclosures for the prior periods, or may apply the amendments retrospectively by providing the revised disclosures for all period presented. The Company expects this ASU to impact disclosures with no impact to the Company’s consolidated financial statements.

Other new pronouncements issued but not effective until after June 30, 2024 are not expected to have a material impact on the Company’s consolidated financial statements.

Subsequent Event

In November 2000, the Company’s Board of Directors authorized the repurchase of up to $30,000,000 of the Company’s Common Stock (the “November 2000 Plan”). The November 2000 Plan authorized the Company to make such repurchases from time to time in the open market or through privately negotiated transactions. As of June 30, 2024, the Company had approximately $8,541,000 remaining available for repurchases of the Company’s Common Stock under the November 2000 Plan. In July 2024, the Company’s Board of Directors authorized the repurchase of up to $100,000,000 of the Company’s Common Stock (the “New Repurchase Authorization”), which replaces, in its entirety, the November 2000 Plan. No further repurchases will be made pursuant to the November 2000 Plan. The timing and amounts of Common Stock repurchases pursuant to the New Repurchase Authorization are at the discretion of the Company’s President and Chief Executive Officer based upon economic and financial market conditions. The New Repurchase Authorization does not expire.

Management’s Discussion and Analysis of

Financial Condition and Results of Operations

June 30, 2024

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

Our quarterly consolidated operating results can be difficult to forecast and have been subject to significant fluctuations. We plan our production and inventory levels based on management’s estimates of customer demand, customer forecasts, and other information sources. Customer forecasts, particularly those of OEM, ODM, and contract manufacturing customers to which we supply Advanced Products in high volumes, are subject to scheduling changes on short notice, contributing to operating inefficiencies and excess costs. In addition, external factors such as supply chain uncertainties, which are often associated with the cyclicality of the electronics industry, regional macroeconomic and trade-related circumstances, and force majeure events (most recently evidenced by the COVID-19 pandemic), have caused our operating results to vary meaningfully. Supply chain disruptions, including those associated with our reliance on outsourced package process steps that are essential in the production of some of our Advanced Products, and those relating, for example, to the procurement of raw material, have in the past negatively impacted and may in the future negatively impact our operating results. We have taken steps to mitigate the impact of supply chain disruptions by, among other things and in varying degrees, moving outsourced manufacturing steps in-house to the Company, ordering supplies with extended lead times, paying higher prices for certain supplies or outsourced production, and expediting deliveries at a cost premium. The resulting

impact of the steps taken to mitigate supply chain disruptions have, to varying degrees and at different times, reduced our revenue, gross margin, operating profit and cash flow and may continue to do so in the future. While we continue to make progress in moving outsourced manufacturing steps in-house to the Company, we are still experiencing long lead times on certain raw material components, and uncertainty of output from our outsourced manufacturing supplier. Our quarterly gross margin as a percentage of net revenues may vary, depending on production volumes, average selling prices, average unit costs, the mix of products sold during that quarter, and the level of importation of raw materials subject to tariffs. Our quarterly operating margin as a percentage of net revenues also may vary with changes in revenue and product level profitability, but our operating costs are largely associated with compensation and related employee costs, which are not subject to sudden or significant changes.

Summary of Second Quarter 2024 Financial Performance Compared to First Quarter 2024 Financial Performance

The following summarizes our financial performance for the second quarter of 2024, compared to the first quarter of 2024:

Net revenues increased 2.4% to $85,854,000 for the second quarter of 2024, from $83,872,000 for the first quarter of 2024. Net revenues for Brick Products decreased 2.7% compared to the first quarter of 2024, primarily due to reduced market demand. Advanced Products net revenues increased 7.1% compared to the first quarter of 2024, primarily due to reduced manufacturing constraints and increased royalty revenue in the second quarter of 2024.
Export sales represented approximately 43.3% of total net revenues in the second quarter of 2024 as compared to 42.6% in the first quarter of 2024.
Gross margin decreased to $42,771,000 for the second quarter of 2024 from $45,123,000 for the first quarter of 2024, with gross margin, as a percentage of net revenues, decreasing to 49.8% for the second quarter of 2024 from 53.8% for the first quarter of 2024. The decrease in gross margin dollars and gross margin percentage was primarily attributable to the overall unfavorable sales mix on slightly higher sales volume in the second quarter of 2024, offset by production efficiencies and lower supply chain costs, including a reduction of freight-in and tariff spending of $1,041,000 (net of approximately $662,000 in duty drawback recovery in the second quarter of 2024 and $0 in duty drawback recovery in the first quarter of 2024 of previously paid tariffs).
Backlog, which represents the total value of orders for products for which shipment is scheduled within the next 12 months, was approximately $153,794,000 at the end of the second quarter of 2024, as compared to $150,340,000 at the end of the first quarter of 2024.
Operating expenses for the second quarter of 2024 decreased $18,681,000, or 30.5%, to $42,557,000 from $61,238,000 for the first quarter of 2024. Selling, general and administrative expenses decreased approximately $2,681,000, primarily due to a decrease in legal expenses. Research and development expenses decreased approximately $1,100,000, primarily due to a decrease in project and pre-production materials. Litigation-contingency expense related to the litigation with SynQor, Inc. ("SynQor") was $2,300,000 for the second quarter of 2024, compared to $17,200,000 for the first quarter of 2024. See Note 10 to the Condensed Consolidated Financial Statements for additional information.
We reported a net loss for the second quarter of 2024 of $(1,196,000), or $(0.03) per diluted share, compared to a net loss of $(14,473,000), or $(0.33) per diluted share, for the first quarter of 2024.
For the second quarter of 2024, depreciation and amortization totaled $4,661,000 and capital additions totaled $6,141,000 as compared to depreciation and amortization of $4,614,000 and capital additions of $7,270,000 for the first quarter of 2023.
Inventories decreased by approximately $3,232,000, or 2.9%, to $109,084,000 at June 30, 2024, compared to $112,316,000 at March 31, 2024.

Three Months Ended June 30, 2024 Compared to Three Months Ended June 30, 2023

Net revenues for the second quarter of 2024 were $85,854,000, a decrease of $20,893,000, or 19.6%, as compared to $106,747,000 for the second quarter of 2023. Net revenues, by product line, for the three months ended June 30, 2024 and 2023 were as follows (dollars in thousands):

Total	$	85,854	$	106,747	$	(20,893	)	(19.6	)%

The decrease in net revenues for Advanced Products was primarily due to our continued softness in underpenetrated markets, partially offset by increased royalty revenue in the quarter.

Gross margin for the second quarter of 2024 decreased $12,402,000, or 22.5%, to $42,771,000, from $55,173,000 for the second quarter of 2023. Gross margin, as a percentage of net revenues, decreased to 49.8% for the second quarter of 2024, compared to 51.7% for the second quarter of 2023. The decrease in gross margin dollars and gross margin percentage was primarily attributable to lower sales volume and to a lesser extent an unfavorable sales mix on that sales volume, offset by higher royalty revenue and production efficiencies and supply chain costs, including a reduction of $782,000 in outsourced manufacturing costs partially offset by incremental costs of bringing production in-house for certain Advanced Products, and an increase in freight-in and tariff spending of $710,000 (net of approximately $662,000 in duty drawback recovery in the second quarter of 2024 and $2,750,000 in duty drawback recovery in the second quarter of 2023 of previously paid tariffs).

Selling, general and administrative expenses were $23,318,000 for the second quarter of 2024, an increase of $2,943,000, or 14.4%, from $20,375,000 for the second quarter of 2023. Selling, general and administrative expenses as a percentage of net revenues increased to 27.2% for the second quarter of 2024 from 19.1% for the second quarter of 2023. The components of the $2,943,000 increase in selling, general and administrative expenses for the second quarter of 2024 from the second quarter of 2023 were as follows (dollars in thousands):

The significant components of ''Other income (expense), net'' for the three months ended June 30, 2024 and 2023 and the changes between the periods were as follows (in thousands):

	2024			2023			Increase (decrease)

Our exposure to market risk fluctuations in foreign currency exchange rates relates to the operations of Vicor Japan Company, Ltd. (“VJCL”), for which the functional currency is the Japanese Yen, and all other subsidiaries in Europe and Asia, for which the functional currency is the U.S. Dollar. These subsidiaries in Europe and Asia experienced less unfavorable foreign currency exchange rate fluctuations in the second quarter of 2024 compared to the second quarter of 2023. Interest income for the three months ended June 30, 2024 increased due to higher balances of cash and cash equivalents held by the Company.

Income before income taxes was $3,021,000 for the second quarter of 2024, as compared to $19,639,000 for the second quarter of 2023.

The provision for income taxes and the effective income tax rates for the three months ended June 30, 2024 and 2023 were as follows (dollars in thousands):

	2024			2023
Provision for income taxes	$	4,216		$	2,537
Effective income tax rate		139.6	%		12.9	%

The effective tax rates differ from the statutory tax rates for the three months ended June 30, 2024 and 2023 primarily due to the Company’s full valuation allowance position against domestic deferred tax assets. The provision for income taxes for the three months ended June 30, 2024 and 2023 included estimated federal, state and foreign income taxes in jurisdictions in which the Company does not have sufficient tax attributes.

The Company’s tax expense and the rate for the quarter continues to be negatively impacted by the capitalization of research and development expenses under Section 174 in the U.S., which given the Company’s close to breakeven performance, is having an outsized impact on the rate by effectively moving from a book loss to a taxable income position, which causes a significant tax expense. This is further compounded by the Company not getting a deferred tax benefit from temporary differences due to the full valuation allowance on domestic deferred tax assets.

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 a net loss for the second quarter of 2024 of $(1,196,000), or $(0.03) per diluted share, compared to net income of $17,101,000, or $0.38 per diluted share, for the second quarter of 2023.

The decrease in net revenues for Advanced Products was primarily due to continued softness in underpenetrated markets, partially offset by increased royalty revenue. The decrease in net revenues for Brick Products was primarily due to reduced market demand.

Gross margin for the six months ended June 30, 2024 decreased $13,813,000, or 13.6%, to $87,894,000 from $101,707,000 for the six months ended June 30, 2023. Gross margin, as a percentage of net revenues, increased to 51.8% for the six month period ended June 30, 2024, as compared to 49.7% for the six month period ended June 30, 2023. The decrease in gross margin dollars was primarily the result of lower sales volume in the first six months of 2024, with the increase in gross margin percentage primarily attributable to improved sales mix on that volume, including royalty revenue, compared to the first six months of 2023 and certain reductions in supply chain costs, including a reduction of $1,967,000 in outsourced manufacturing costs partially offset by incremental costs of bringing production in-house for certain Advanced Products, and an increase in freight-in and tariff spending of $1,932,000 (net of approximately $662,000 in duty drawback recovery in the first six months of 2024 and $5,715,000 in duty drawback recovery in the first six months of 2023 of previously paid tariffs).

Selling, general and administrative expenses were $49,317,000 for the six months ended June 30, 2024, an increase of $8,719,000, or 21.5%, compared to $40,598,000 for the six months ended June 30, 2023.

The effective tax rates differ from the statutory tax rates for the six months ended June 30, 2024 and 2023 primarily due to the Company’s full valuation allowance position against domestic deferred tax assets. The provision for income taxes for the six months ended June 30, 2024 and 2023 included estimated federal, state and foreign income taxes in jurisdictions in which the Company does not have sufficient tax attributes.

This is further compounded by the Company not getting a deferred tax benefit from temporary differences due to the full valuation allowance on domestic deferred tax assets.

We reported a net loss for the six months ended June 30, 2024 of $(15,669,000), or $(0.35) per diluted share, as compared to net income of $28,345,000, or $0.63 per diluted share, for the six months ended June 30, 2023.

Liquidity and Capital Resources

As of June 30, 2024, we had $251,884,000 in cash and cash equivalents. The ratio of total current assets to total current liabilities was 6.4:1 as of June 30, 2024 and 9.5:1 as of December 31, 2023. Working capital, defined as total current assets less total current liabilities, decreased $8,698,000 to $367,499,000 as of June 30, 2024 from $376,197,000 as of December 31, 2023.

The primary sources of cash for the six months ended June 30, 2024 were $18,148,000 generated from operations, and $5,138,000 received in connection with the exercise of options to purchase our Common Stock awarded under our stock option plans and the issuance of Common Stock under our 2017 Employee Stock Purchase Plan. The primary uses of cash during the six months ended June 30, 2024 were for the purchase of property and equipment of $13,411,000.

In November 2000, our Board of Directors authorized the repurchase of up to $30,000,000 of our Common Stock (the “November 2000 Plan”). The November 2000 Plan authorized us to make such repurchases from time to time in the open market or through privately negotiated transactions. We did not repurchase shares of Common Stock under the November 2000 Plan during the

three months ended June 30, 2024. As of June 30, 2024, we had approximately $8,541,000 remaining available for repurchases of our Common Stock under the November 2000 Plan.

In July 2024, our Board of Directors authorized the repurchase of up to $100,000,000 of our Common Stock (the “New Repurchase Authorization”). The New Repurchase Authorization replaces the November 2000 Plan in its entirety and no further repurchases will be made pursuant to the November 2000 Plan. See Note 12 to the Condensed Consolidated Financial Statements for additional information.

The timing and amounts of Common Stock repurchases under the New Repurchase Authorization are at the discretion of the Company’s President and Chief Executive Officer based upon economic and financial market conditions.

As of June 30, 2024, we had a total of approximately $14,986,000 of cancelable and non-cancelable capital expenditure commitments, principally for manufacturing and production equipment, which we intend to fund with existing cash, and approximately $2,133,000 of capital expenditure items and internal-use software which had been received and included in Property, plant and equipment, net in the accompanying Condensed Consolidated Balance Sheets, but not yet paid for. Our primary needs for liquidity are for making continuing investments in manufacturing and production equipment. We believe cash generated from operations together with our available cash and cash equivalents will be sufficient to fund planned operational needs and capital equipment purchases, for both the short and long term.

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

Critical Accounting Policies and Estimates

There have been no material changes in our judgments and assumptions associated with the development of our critical accounting estimates during the period ended June 30, 2024. Refer to the section entitled “Critical Accounting Policies and Estimates” in Part II, Item 7 – “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

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, 2024, our long-term investment portfolio, recorded on our Condensed Consolidated Balance Sheet as “Long-term investment, net”, consisted of a single auction rate security with a par value of $3,000,000, purchased through and held in custody by a broker-dealer affiliate of Bank of America, N.A., that has experienced failed auctions (the “Failed Auction Security”) since February 2008. While the Failed Auction Security is Aaa/AA+ rated by major credit rating agencies, collateralized by student loans and guaranteed by the U.S. Department of Education under the Federal Family Education Loan Program, continued failure to sell at its periodic auction dates (i.e., reset dates) could negatively impact the carrying value of the investment, in turn leading to impairment charges in future periods. Periodic changes in the fair value of the Failed Auction Security attributable to credit loss (i.e., risk of the issuer’s default) are recorded through earnings as a component of “Other income (expense), net”, with the remainder of any periodic change in fair value not related to credit loss (i.e., temporary “mark-to-market” carrying value adjustments) recorded in “Accumulated other comprehensive loss”, a component of Stockholders’ Equity. Should we conclude a decline in the fair value of the Failed Auction Security is other than temporary, such losses would be recorded through earnings as a component of “Other income (expense), net”. We do not believe there was an “other-than-temporary” decline in value in this security as of June 30, 2024.

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

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, 2024). 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, 2024, 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.

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, 2024, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
