(1)
The deferred tax assets associated with foreign currency translation losses 
and unrealized gains on available-for-sale securities are completely offset by 
a tax valuation allowance as of
March 31, 2024 and 2023
. Therefore, there is
no
income tax benefit (provision) recognized for the three months ended
March 31, 2024 and 2023
.

Basis of Presentation
The accompanying unaudited Condensed Consolidated Financial Statements of 
Vicor Corporation and its consolidated subsidiaries (collectively, the 
"Company") have been prepared in accordance with generally accepted accounting 
principles for interim financial information and pursuant to the rules and 
regulations of the Securities and Exchange Commission (the "SEC"). 
Accordingly, these interim financial statements do not include all of the 
information and footnotes required by generally accepted accounting principles 
for complete financial statements.
In the opinion of management, all adjustments (consisting of normal recurring 
adjustments) considered necessary for a fair presentation have been included. 
Operating results for the three months ended March 31, 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 March 31, 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 $
2,622,000
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
March 31, 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
March 31, 2024.

Fair Value Measurements
The Company accounts for certain financial assets at fair value, defined as 
the price that would be received to sell an asset or paid to transfer a 
liability (i.e., an exit price) in the principal or most advantageous market 
for the asset or liability in an orderly transaction between market 
participants on the measurement date. As such, fair value is a market-based 
measurement that should be determined based on assumptions market participants 
would use in pricing an asset or liability. A three-level hierarchy is used to 
show the extent and level of judgment used to estimate fair value measurements.

Assets and liabilities measured at fair value on a recurring basis included 
the following as of
March 31, 2024 (in thousands):

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 $
360,000
and approximately $
1,609,000
for the three months ended
March 31, 2024 and 2023
, respectively, that was included in deferred revenue at the beginning of the 
respective period.

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.

facility leased to a third party in California, was approximately $
198,000
for each of the three month periods ended
March 31, 2024 and 2023.

8.
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):

                                       -

                                 8.0                 


The effective tax rates differ from the statutory tax rates for the three 
months ended March 31, 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 March 31, 2024 and 2023 
included estimated federal, state and foreign income taxes in jurisdictions in 
which the Company does not have sufficient tax attributes.
As of March 31, 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. 
Despite recent positive operating results, the Company faces uncertainties in 
forecasting its operating results due to supply and factory capacity 
constraints, certain process issues with the production of Advanced Products 
and the unpredictability in certain markets. This operating uncertainty also 
makes it difficult to predict the availability and utilization of tax benefits 
over the next several years. As a result, management has concluded, as of 
March 31, 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
March 31, 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 positive 
operating results continue, and the Company's concerns about industry 
uncertainty and world events, supply and factory capacity constraints, and 
process issues with the production of Advanced Products are resolved, and the 
amount of tax benefits the Company is able to utilize to the point that the 
Company believes future taxable income can be more reliably forecasted, the 
Company may release all or a portion of the valuation allowance in the 
near-term. If and when the Company determines the valuation allowance should 
be released (i.e., reduced), the adjustment would result in a tax benefit 
reported in that period's Condensed Consolidated Statements of Operations, the 
effect of which would be an increase in reported net income.
The Company was informed in September 2021 by the Internal Revenue Service of 
their intention to examine the Company's 2019 Federal income tax return. The 
IRS is in the process of closing examination of the 2019 tax year with no 
material adjustments. There are no other audits or examinations in process in 
any other jurisdiction.

Commitments and Contingencies
At March 31, 2024
, the Company had approximately $
11,475,000
of cancelable and non-cancelable capital expenditure commitments, principally 
for manufacturing 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 "District Court"). The complaint, as 
amended, alleged that the Company's unregulated bus converters used in 
intermediate bus architecture power supply systems infringed SynQor's U.S. 
patent numbers 7,072,190, 7,272,021, 7,564,702, and 8,023,290 ("the `190 
patent", "the `021 patent", "the `702 patent", and "the `290 patent", 
respectively, and collectively the "SynQor Patents"). The Company asserted 
counterclaims against SynQor alleging unfair competition and tortious 
interference with business relations (the "Counterclaims"). As a result of 
certain actions by the United States Patent and Trademark Office ("USPTO") and 
the District Court, SynQor's infringement allegations regarding the `021 
patent and the `290 patent were dismissed from the case prior to the beginning 
of trial. Specifically, the USPTO invalidated all the asserted claims of the 
`021 patent and that decision was upheld on appeal on August 30, 2017. In 
addition, on October 5, 2022, the District Court issued an order involuntarily 
dismissing the `290 patent infringement allegations on grounds of equitable 
and judicial estoppel, in view of representations by SynQor to the District 
Court agreeing to such dismissal as a condition of lifting a prior stay of the 
lawsuit. On January 18, 2023, the United States Court of Appeals for the 
Federal Circuit issued a decision upholding a decision of the Patent Trial and 
Appeal Board of the USPTO invalidating all claims of the `290 patent.
A trial in the District Court began on October 17, 2022 on the asserted claims 
of the `190 patent and the `702 patent, as well as on the Company's 
Counterclaims. The District Court dismissed the Company's Counterclaims on 
October 25, 2022. On October 26, 2022, the jury returned a verdict on SynQor's 
patent infringement claims, finding that the Company willfully infringed the 
`702 patent, but did not infringe the `190 patent. The jury verdict awarded 
SynQor damages in the amount of $
6,500,000
for infringement of the `702 patent. All of the SynQor Patents expired in 2018.
On December 23, 2022, SynQor filed in the District Court (a) a motion for 
judgment as a matter of law that the Company infringed the `190 patent, (b) a 
motion requesting the District Court to award SynQor treble damages, as well 
as pre- and post-judgment interest, (c) a motion requesting the District Court 
to award SynQor its attorneys' fees, and (d) a motion for a new trial. On 
December 23, 2022, the Company filed in the District Court (a) a motion 
requesting judgment as a matter of law that it did not infringe the `702 
patent, and (b) a motion requesting judgment with respect to its defenses of 
equitable estoppel and waiver. On January 8, 2024, the District Court issued 
orders denying (a) SynQor's motion for judgment as a matter of law, (b) the 
Company's
                                       -

motion for judgment as a matter of law, (c) the Company's motion for judgment 
with respect to its defenses of equitable estoppel and waiver and (d) SynQor's 
motion for a new trial.
On April 24, 2024, the District Court issued an order granting SynQor's 
motions for enhanced damages, pre-judgment and post-judgment interest, costs 
and attorneys' fees. Specifically, the District Court determined that the 
jury's damages award of $
6,500,000
should be enhanced by $
4,500,000
. The District Court also granted SynQor an award of costs in the amount of 
approximately $
87,000
. The District Court also awarded SynQor pre-judgment interest at the 2009 
prime rate, compounded quarterly beginning in July 2009, as well as 
post-judgment interest at the statutory rate. The District Court also awarded 
SynQor its attorneys' fees relating to the assertion of the `702 patent, in an 
amount to be determined based upon the District Court's consideration of 
subsequent submissions by SynQor.
The Company anticipates appealing the District Court's final judgment to the 
United States Court of Appeals for the Federal Circuit.
In accordance with applicable accounting standards, the Company recorded a 
litigation related accrual of $
6,500,000
in the third quarter of 2022 and an incremental litigation related accrual of $
17,200,000
in the first quarter of 2024 as its estimate based on the awarded judgments, 
including enhanced damages, pre-judgment interest, costs and estimated 
attorneys' fees. The final determination of attorneys' fees and any associated 
pre-judgment and post-judgment interest will depend on the District Court's 
determination of those fees and interest amounts, subject to appeal, and could 
differ from the recorded liability.
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 has not yet determined the impact of this 
ASU on the Company's consolidated financial statements and disclosures.
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

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 ArchitectureTM ("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.
Changes from Previously Disclosed Results
As discussed below, we reported a net loss for the first quarter of 2024 of 
$(14,473,000), or $(0.33) per diluted share, compared to $11,244,000, or $0.25 
per diluted share, for the first quarter of 2023. Initially, in our earnings 
release issued on April 23, 2024, we disclosed net income for the first 
quarter of 2024 of $2,604,000, or $0.06 per diluted share. On April 24, 2024, 
after the issuance of our earnings release and completion of the related 
earnings call, the U.S. District Court for the Eastern District of Texas (the 
"District Court") issued an order granting SynQor, Inc.'s motions for enhanced 
damages, pre-judgment and post-judgment interest, costs and attorneys' fees. 
The District Court also entered a final judgment reflecting these rulings. The 
Company anticipates appealing the District Court's final judgment to the 
United States Court of Appeals for the Federal Circuit.
In light of this judgment, in accordance with applicable accounting standards, 
we recorded an incremental litigation related loss reserve of $17,200,000 in 
the first quarter of 2024, resulting in the decrease in our reported net 
income and net income per share from the amounts previously disclosed in our 
earnings release, as well as a corresponding $17,200,000 increase in operating 
expenses to $61,238,000 from the previously disclosed $44,038,000. See Note 10 
to the Condensed Consolidated Financial Statements for additional information 
regarding the SynQor litigation and loss reserve.
Summary of First Quarter 2024 Financial Performance Compared to Fourth Quarter 
2023 Financial Performance
The following summarizes our financial performance for the first quarter of 
2024, compared to the fourth quarter of 2023:
.
Net revenues decreased 9.5% to $83,872,000 for the first quarter of 2024, from 
$92,652,000 for the fourth quarter of 2023. Net revenues for Brick Products 
decreased 11.7% compared to the fourth quarter of 2023, primarily due to 
reduced market demand and lower available backlog. Advanced Products net 
revenues decreased 7.3% compared to the fourth quarter of 2023, primarily due 
to our continued softness in underpenetrated markets, partially offset by 
increased royalty revenue in the quarter.
.
Export sales represented approximately 42.6% of total net revenues in the 
first quarter of 2024 as compared to 56.5% in the fourth quarter of 2023.
.
Gross margin decreased to $45,123,000 for the first quarter of 2024 from 
$47,344,000 for the fourth quarter of 2023, with gross margin, as a percentage 
of net revenues, increasing to 53.8% for the first quarter of 2024 from 51.1% 
for the fourth quarter of 2023. The decrease in gross margin dollars was 
primarily the result of lower sales volume in the first quarter of 2024, with 
the increase in gross margin percentage primarily attributable to improved 
sales mix on that volume and a reduction of freight-in and tariff spending of 
$153,000 (net of approximately $0 in duty drawback recovery in the first 
quarter of 2024 and $1,239,000 in duty drawback recovery in the fourth quarter 
of 2023 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 
$150,340,000 at the end of the first quarter of 2024, as compared to 
$160,805,000 at the end of the fourth quarter of 2023.
.
Operating expenses for the first quarter of 2024 increased $22,543,000, or 
56.4%, to $62,538,000 from $39,995,000 for the fourth quarter of 2023. 
Selling, general and administrative expenses increased approximately 
$3,305,000, primarily due to an increase in legal expenses. Research and 
development expenses increased approximately $738,000, primarily due to an 
increase in compensation expense. Litigation-contingency expense related to 
the SynQor litigation was $17,200,000 for the first quarter of 2024, with no 
comparable expense in the fourth quarter of 2023. See Note 10 to the Condensed 
Consolidated Financial Statements for additional information.

.
We reported a net loss for the first quarter of 2024 of $(14,473,000), or 
$(0.33) per diluted share, compared to net income of $8,668,000, or $0.19 per 
diluted share, for the fourth quarter of 2023.
.
For the first quarter of 2024, depreciation and amortization totaled 
$4,614,000 and capital additions totaled $7,270,000 as compared to 
depreciation and amortization of $4,038,000 and capital additions of 
$7,163,000 for the fourth quarter of 2023.
.
Inventories increased by approximately $5,737,000, or 5.4%, to $112,316,000 at 
March 31, 2024, compared to $106,579,000 at December 31, 2023.
Three Months Ended March 31, 2024 Compared to Three Months Ended March 31, 2023
Net revenues for the first quarter of 2024 were $83,872,000, a decrease of 
$13,944,000, or 14.3%, as compared to $97,816,000 for the first quarter of 
2023. Net revenues, by product line, for the three months ended March 31, 2024 
and 2023 were as follows (dollars in thousands):


                                               Decrease

Advanced Products  $ 43,280    $ 51,291   $  (8,011 )   (15.6 )%
Brick Products       40,592      46,525      (5,933 )   (12.8 )%
Total              $ 83,872    $ 97,816   $ (13,944 )   (14.3 )%


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. The decrease in net revenues for Brick 
Products was primarily due to reduced market demand and lower available 
backlog.
Gross margin for the first quarter of 2024 decreased $1,411,000, or 3.0%, to 
$45,123,000, from $46,534,000 for the first quarter of 2023. Gross margin, as 
a percentage of net revenues, increased to 53.8% for the first quarter of 
2024, compared to 47.6% for the first quarter of 2023. The decrease in gross 
margin dollars was primarily the result of lower sales volume in the first 
quarter 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 quarter of 2023 and certain reductions in supply chain 
costs, including a reduction of $1,185,000 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 $1,222,000 (net of approximately $0 in duty drawback recovery in the first 
quarter of 2024 and $2,965,000 in duty drawback recovery in the first quarter 
of 2023 of previously paid tariffs).
Selling, general and administrative expenses were $25,999,000 for the first 
quarter of 2024, an increase of $5,776,000, or 28.6%, from $20,223,000 for the 
first quarter of 2023. Selling, general and administrative expenses as a 
percentage of net revenues increased to 31.0% for the first quarter of 2024 
from 20.7% for the first quarter of 2023. The components of the $5,776,000

  $ 2,724   $ 1,950   $ 774 


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 more unfavorable foreign currency 
exchange rate fluctuations in the first quarter of 2024 compared to the first 
quarter of 2023. Interest income for the three months ended March 31, 2024 
increased due to higher interest rates received on the cash and cash 
equivalents balance the Company holds.
Loss before income taxes was $(13,391,000) for the first quarter of 2024,
as compared to income before taxes of $12,392,000 for the first quarter of 2023.
The provision for income taxes and the effective income tax rates for the 
three months ended March 31, 2024 and 2023 were as follows (dollars in 
thousands):


                             2024        2023    
Provision for income taxes  $ 1,071     $ 1,141  
Effective income tax rate      (8.0 )%      9.2 %


The effective tax rates differ from the statutory tax rates for the three 
months ended March 31, 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 March 31, 2024 and 2023 
included estimated federal, state and foreign income taxes in jurisdictions in 
which the Company does not have sufficient tax attributes.
See Note 8 to the Condensed Consolidated Financial Statements for disclosure 
regarding our current assessment of the valuation allowance against all 
domestic deferred tax assets, and the possible release (i.e., reduction) of 
the allowance in the future.
We reported net loss for the first quarter of 2024 of $(14,473,000), or 
$(0.33) per diluted share, compared to $11,244,000, or $0.25 per diluted 
share, for the first quarter of 2023.
Liquidity and Capital Resources
As of March 31, 2024, we had $239,172,000 in cash and cash equivalents. The 
ratio of total current assets to total current liabilities was 6.7:1 as of 
March 31, 2024 and 9.5:1 as of December 31, 2023. Working capital, defined as 
total current assets less total current liabilities, decreased $12,013,000 to 
$364,184,000 as of March 31, 2024 from $376,197,000 as of December 31, 2023.

The primary sources of cash for the three months ended March 31, 2024 were 
$2,582,000 generated from operations, and $1,756,000 received in connection 
with the exercise of options to purchase our Common Stock awarded under our 
stock option plans and the issuance of Common Stock under our 2017 Employee 
Stock Purchase Plan. The primary uses of cash during the three months ended 
March 31, 2024 were for the purchase of property and equipment of $7,270,000.

In November 2000, our Board of Directors authorized the repurchase of up to 
$30,000,000 of our Common Stock (the "November 2000 Plan"). The November 2000 
Plan authorizes us to make such repurchases from time to time in the open 
market or through privately negotiated transactions. The timing and amounts of 
Common Stock repurchases are at the discretion of management based on its view 
of economic and financial market conditions. We did not repurchase shares of 
Common Stock under the November 2000 Plan during the three months ended March 
31, 2024. As of March 31, 2024, we had approximately $8,541,000 remaining 
available for repurchases of our Common Stock under the November 2000 Plan.

As of March 31, 2024, we had a total of approximately $11,475,000 of 
cancelable and non-cancelable capital expenditure commitments, principally for 
manufacturing and production equipment, which we intend to fund with existing 
cash, and approximately $1,983,000 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 March 31, 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 Qu
alitative Disclosures About Market Risk
We are exposed to a variety of market risks, including changes in interest 
rates affecting the return on our cash and cash equivalents, our short-term 
investments and fluctuations in foreign currency exchange rates. As our cash 
and cash equivalents and short-term investments consist principally of cash 
accounts, money market securities, and U.S. Treasury securities, which are 
short-term in nature, we believe our exposure to market risk on interest rate 
fluctuations for these investments is not significant. As of March 31, 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 March 31, 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 - Contr
ols and Procedures
(a)
Disclosure regarding controls and procedures.
As required by Rule 13a-15 under the Securities Exchange Act of 1934, as 
amended (the "Exchange Act"), management, with the participation of our Chief 
Executive Officer ("CEO") (who is our principal executive officer) and Chief 
Financial Officer ("CFO") (who is our principal financial officer), conducted 
an evaluation of the effectiveness of our disclosure controls and procedures 
as of the end of the last fiscal quarter (i.e., March 31, 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 March 31, 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.

(b)
Changes in internal control over financial reporting.
There was no change in our internal control over financial reporting that 
occurred during the fiscal quarter ended March 31, 2024, that has materially 
affected, or is reasonably likely to materially affect, our internal control 
over financial reporting.

                     CHIEF EXECUTIVE OFFICER CERTIFICATION                      
I,
Patrizio Vinciarelli
, certify:
1.
I have reviewed this Quarterly Report on Form 10-Q of Vicor Corporation;
2.
Based on my knowledge, this report does not contain any untrue statement of a 
material fact or omit to state a material fact necessary to make the 
statements made, in light of the circumstances under which such statements 
were made, not misleading with respect to the period covered by this report;

3.
Based on my knowledge, the financial statements, and other financial 
information included in this report, fairly present in all material respects 
the financial condition, results of operations and cash flows of the 
registrant as of, and for, the periods presented in this report;
4.
The registrants other certifying officer and I are responsible for 
establishing and maintaining disclosure controls and procedures (as defined in 
Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over 
financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) 
for the registrant and have:
a)
Designed such disclosure controls and procedures, or caused such disclosure 
controls and procedures to be designed under our supervision, to ensure that 
material information relating to the registrant, including its consolidated 
subsidiaries, is made known to us by others within those entities, 
particularly during the period in which this report is being prepared;

b)
Designed such internal control over financial reporting, or caused such 
internal control over financial reporting to be designed under our 
supervision, to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external 
purposes in accordance with generally accepted accounting principles;
c)
Evaluated the effectiveness of the registrants disclosure controls and 
procedures and presented in this report our conclusions about the 
effectiveness of the disclosure controls and procedures, as of the end of the 
period covered by this report based on such evaluation; and
d)
Disclosed in this report any change in the registrants internal control over 
financial reporting that occurred during the registrants most recent fiscal 
quarter (the registrants fourth fiscal quarter in the case of an annual 
report) that has materially affected, or is reasonably likely to materially 
affect, the registrants internal control over financial reporting; and
5.
The registrants other certifying officer and I have disclosed, based on our 
most recent evaluation of internal control over financial reporting, to the 
registrants auditors and the audit committee of the registrants board of 
directors (or persons performing the equivalent functions):
a)
All significant deficiencies and material weaknesses in the design or 
operation of internal control over financial reporting which are reasonably 
likely to adversely affect the registrants ability to record, process, 
summarize and report financial information; and
b)
Any fraud, whether or not material, that involves management or other 
employees who have a significant role in the registrants internal control over 
financial reporting.

                     CHIEF FINANCIAL OFFICER CERTIFICATION                      
I,
James F. Schmidt
, certify:
1.
I have reviewed this Quarterly Report on Form 10-Q of Vicor Corporation;
2.
Based on my knowledge, this report does not contain any untrue statement of a 
material fact or omit to state a material fact necessary to make the 
statements made, in light of the circumstances under which such statements 
were made, not misleading with respect to the period covered by this report;

3.
Based on my knowledge, the financial statements, and other financial 
information included in this report, fairly present in all material respects 
the financial condition, results of operations and cash flows of the 
registrant as of, and for, the periods presented in this report;
4.
The registrants other certifying officer and I are responsible for 
establishing and maintaining disclosure controls and procedures (as defined in 
Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over 
financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) 
for the registrant and have:
a)
Designed such disclosure controls and procedures, or caused such disclosure 
controls and procedures to be designed under our supervision, to ensure that 
material information relating to the registrant, including its consolidated 
subsidiaries, is made known to us by others within those entities, 
particularly during the period in which this report is being prepared;

b)
Designed such internal control over financial reporting, or caused such 
internal control over financial reporting to be designed under our 
supervision, to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external 
purposes in accordance with generally accepted accounting principles;
c)
Evaluated the effectiveness of the registrants disclosure controls and 
procedures and presented in this report our conclusions about the 
effectiveness of the disclosure controls and procedures, as of the end of the 
period covered by this report based on such evaluation; and
d)
Disclosed in this report any change in the registrants internal control over 
financial reporting that occurred during the registrants most recent fiscal 
quarter (the registrants fourth fiscal quarter in the case of an annual 
report) that has materially affected, or is reasonably likely to materially 
affect, the registrants internal control over financial reporting; and
5.
The registrants other certifying officer and I have disclosed, based on our 
most recent evaluation of internal control over financial reporting, to the 
registrants auditors and the audit committee of the registrants board of 
directors (or persons performing the equivalent functions):
a)
All significant deficiencies and material weaknesses in the design or 
operation of internal control over financial reporting which are reasonably 
likely to adversely affect the registrants ability to record, process, 
summarize and report financial information; and
b)
Any fraud, whether or not material, that involves management or other 
employees who have a significant role in the registrants internal control over 
financial reporting.
