(the &#147;Company&#148;) 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

information and footnotes required by generally accepted accounting principles for complete
financial statements.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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&nbsp;31, 2011, are not necessarily indicative of the results that may be expected
for any other interim period or the year ending December&nbsp;31, 2011. The balance sheet at December
31, 2010, 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

</DIV>



<!-- xbrl,body -->
<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;s principal sources of liquidity are its existing balances of cash and cash
equivalents and short-term investments, as well as cash generated from operations. Consistent
with the Company&#146;s investment policy guidelines, the Company can invest, and has historically
invested, its cash balances in demand deposit accounts, money market funds and auction rate
securities meeting certain quality criteria. All of the Company&#146;s investments are subject to
credit, liquidity, market, and interest rate risk.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;s long-term investments are classified as available-for-sale.
Available-for-sale securities are recorded at fair value, with unrealized gains and losses, net
of tax, attributable to credit loss recorded through the statement of operations and unrealized
gains and losses, net of tax, attributable to other non-credit factors recorded in &#147;Accumulated
other comprehensive loss&#148;, a component of Stockholders&#146; Equity. 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 securities, considering, among other factors, credit default risk
probabilities and changes in credit ratings as significant inputs.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The amortized cost of debt securities is adjusted for amortization of premiums and accretion
of discounts to maturity, the net amount of which, along with interest and realized gains and
losses, is included in &#147;Other income (expense), net&#148; in the Condensed Consolidated Statements of
Operations. The Company periodically evaluates investments to determine if impairment is
required, whether an impairment is other than temporary, and the measurement of an impairment
loss. The Company considers a variety of impairment indicators such as, but not limited to, a
significant deterioration in the earnings performance, credit rating, or asset quality of the
investment.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of March&nbsp;31, 2011, the Company held par value of $18,975,000 of auction rate securities.
These auction rate securities consist of collateralized debt obligations, supported by pools of
student loans, sponsored by state student loan agencies and corporate student loan servicing
firms. The interest rates for these securities are reset at auction at regular intervals ranging
from seven to 90&nbsp;days. The auction rate securities held by the Company traded at par prior to
February&nbsp;2008 and are callable at par at the option of the issuer.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Until February&nbsp;2008, the auction rate securities market was liquid, as the investment banks
conducting the periodic &#147;Dutch auctions&#148; by which interest rates for the securities had been
established had committed their capital to support such auctions in the event of insufficient
third-party investor demand. Starting the week of February&nbsp;11, 2008, a substantial number of
auctions failed, as demand from third-party investors weakened and the investment banks
conducting the auctions chose not to commit capital to support such auctions (i.e., investment
banks chose not to purchase securities themselves in order to balance supply and demand, thereby
facilitating a successful auction, as they had done in the past). The consequences of a failed
auction are (a)&nbsp;an investor must hold the specific security until the next scheduled auction
(unless that investor chooses to sell the security to a third party outside of the auction process) and (b)&nbsp;the interest rate on the security generally resets
to an interest rate set forth in each security&#146;s indenture.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of March&nbsp;31, 2011, the Company held auction rate securities that had experienced failed
auctions totaling $18,975,000 at par value, all of which had been purchased through and are held
by a broker-dealer affiliate of Bank of America, N.A. (the &#147;Failed Auction Securities&#148;). As of
March&nbsp;31, 2011, the majority of the Failed Auction Securities held by the Company were AAA/Aaa
rated by the major credit rating agencies, with all of the securities collateralized by student
loans, of which most are guaranteed by the U.S. Department of Education under the Federal Family
Education Loan Program. Management is not aware of any reason to believe any of the issuers of
the Failed Auction Securities held by the Company are presently at risk of default. Through
March&nbsp;31, 2011, the Company has continued to receive interest payments on the Failed Auction
Securities in accordance with the terms of their respective indentures. In April&nbsp;2011, two of
the Failed Auction Securities outstanding as of March&nbsp;31, 2011 with an aggregate par value of
$5,500,000 were redeemed at par. Management believes the Company ultimately should be able to
liquidate all of its Failed Auction Securities without significant loss primarily due to the
overall quality of the issues held and the collateral securing the substantial majority
of the underlying obligations. However, current conditions in the auction rate securities market
have led management to conclude the recovery period for the Failed Auction Securities exceeds 12
months. As a result, the Company continued to classify the Failed Auction Securities as
long-term as of March&nbsp;31, 2011.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Based on the fair value measurements described in Note 3, the fair value of the Failed
Auction Securities on March&nbsp;31, 2011, with a par value of $18,975,000, was estimated by the
Company to be approximately $16,251,000, an increase in fair value of $32,000, net of $100,000 of
redemptions from December&nbsp;31, 2010. The gross unrealized loss of $2,724,000 on the Failed Auction
Securities consists of two types of estimated loss: an aggregate credit loss of $603,000 and an
aggregate temporary impairment of $2,121,000. For the three months ended March&nbsp;31, 2011, the
aggregate credit loss on the Failed Auction Securities decreased by a net amount of $7,000, which
was recorded in &#147;Net impairment gains (losses)&nbsp;recognized in earnings&#148; in the Condensed
Consolidated Statement of Operations. 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 securities, considering credit default risk probabilities and changes in credit ratings as
significant inputs, among other factors (See Note 3).

&#147;Accumulated other comprehensive loss&#148; in the Condensed Consolidated Balance Sheet by $132,000 to
reflect an increase in the estimated fair value of the Failed Auction Securities.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At this time, the Company has no intent to sell any of the impaired Failed Auction
Securities and does not believe it is more likely than not the Company will be required to sell
any of these securities. Management expects the securities to regain liquidity as the financial
markets recover from the current economic downturn. If current market conditions deteriorate
further, the Company may be required to record additional unrealized losses. If the credit
rating of the security deteriorates, or the anticipated recovery in the market values does not
occur, the Company may be required to adjust the carrying value of these investments through
impairment charges recorded in the Condensed Consolidated Statement of Operations, and any such
impairment adjustments may be material.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Based on the Company&#146;s ability to access cash and cash equivalents and its expected
operating cash flows, management does not anticipate the current lack of liquidity associated
with the Failed Auction Securities held will affect the Company&#146;s ability to execute its current
operating plan.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company has brokered certificates of deposit that are classified as Level 2 due to the
fact that the fair value for these investments is determined utilizing observable inputs from
non-active markets. The fair values fluctuate with changes in market interest rates which are
derived from information available in publicly quoted markets.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of March&nbsp;31, 2011, there was insufficient observable auction rate security market
information available to determine the fair value of the Failed Auction Securities using Level 1
or Level 2 inputs. As such, the Company&#146;s investments in Failed Auction Securities were deemed
to require valuation using Level 3 inputs. Management, after consulting with advisors, valued
the Failed Auction Securities 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&#146;s interest rate was set). Management
utilized a probability weighted discounted cash flow (&#147;DCF&#148;) model to determine the estimated
fair value of these securities as of March&nbsp;31, 2011. The major assumptions used in preparing the
DCF model included estimates for the amount and timing of future interest and principal payments
based on default probability assumptions used to measure the credit loss of approximately 3%, the
rate of return required by investors to own these securities in the current environment, which
management estimates to be 5% above the risk free rate of return, and the estimated timeframe for
successful auctions for these securities to occur being three to five years. In making these
assumptions, management considered relevant factors including: the formula applicable to each
security defining the interest rate paid to investors in the event of a failed auction; forward
projections of the interest rate benchmarks specified in such formulas; the likely timing of
principal repayments; the probability of full repayment considering the guarantees by the U.S.
Department of Education of the underlying student loans, guarantees by other third parties, and
additional credit enhancements provided through other means; and publicly available pricing data
for recently issued student loan asset-backed securities not subject to auctions. The estimate
of the rate of return required by investors
to own these securities also considered the currently reduced liquidity for auction rate
securities. An increase or decrease in the liquidity risk premium (i.e., the discount rate) of
100 basis points as used in the model would decrease or increase, respectively, the fair value of
the Failed Auction Securities by approximately $800,000.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">During the third quarter of 2010, the Company granted 1,243,750 non-qualified stock options
under the Vicor Corporation Amended and Restated 2000 Stock Option and Incentive Plan (the &#147;2000
Plan&#148;), with performance-based vesting provisions tied to achievement of certain quarterly
revenue targets by the Brick Business Unit. Under the accounting rules for performance-based
awards, the Company is required to assess, on an ongoing basis, the probability of whether the
performance criteria will be achieved. If and when achievement is deemed probable, the Company
will begin to recognize the associated compensation expense for the stock options over the
relevant performance period. As of March&nbsp;31, 2011, the Company determined that it was not
probable that the revenue targets could be achieved and, accordingly, has not recorded any
compensation expense relating to these options since the grant date. The unrecognized
compensation expense of these performance-based options was approximately $7,790,000 as of March
31, 2011.

that it was probable that the margin targets could be achieved and, accordingly, began recording
compensation expense relating to these options beginning January&nbsp;1, 2011. The unrecognized
compensation expense of these performance-based options was approximately $1,410,000 as of March

value is based upon its known backlog, projected future demand and expected market conditions.
If the Company&#146;s estimated demand and / or market expectation were to change or if product sales
were to decline, the Company&#146;s estimation process may cause larger inventory reserves to be
recorded, resulting in larger charges to cost of revenues.

Semiconductor Corporation (&#147;GWS&#148;) totaled $5,000,000 as of March&nbsp;31, 2011, and December&nbsp;31, 2010,
giving the Company an approximately 30% ownership interest in GWS. GWS and its subsidiary design
and sell semiconductors, conduct research and development activities, develop and license
patents, and litigate against those who infringe upon patented technology. A director of the
Company is the founder, Chairman of the Board, President and Chief Executive Officer (&#147;CEO&#148;), as
well as the majority voting shareholder, of GWS. The Company and GWS are parties to an
intellectual property cross-licensing agreement, a license agreement and two supply agreements
under which the Company purchases certain components from GWS. Purchases from GWS totaled
approximately $804,000 and $671,000 for the three months ended March&nbsp;31, 2011, and 2010,
respectively.
</DIV>



<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;
The Company accounts for its investment in GWS under the equity method of accounting. The
Company has determined that, while GWS is a variable interest entity, the Company is not the
primary beneficiary. The key factors in the Company&#146;s assessment were that the CEO of GWS has:
(i)&nbsp;the power to direct the activities of GWS that most significantly impact its economic
performance, and (ii)&nbsp;has an obligation to absorb losses or the right to receive benefits from
GWS, respectively, that could potentially be significant to GWS.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
There was no allocation of equity method income (loss)&nbsp;for the three months ended March&nbsp;31,
2011 and 2010, as GWS incurred a net loss in each period. The balance in the Company&#146;s
investment in GWS was zero as of March&nbsp;31, 2011 and December&nbsp;31, 2010.

The Company generally offers a two-year warranty for all of its products. The Company
provides for the estimated cost of product warranties at the time product revenue is recognized.
Factors that affect the Company&#146;s warranty reserves include the number of units sold, historical
and anticipated rates of warranty returns, and the cost per return. The Company periodically
assesses the adequacy of the warranty reserves and adjusts the amounts as necessary. Warranty
obligations are included in &#147;Accrued expenses&#148; in the accompanying Condensed Consolidated Balance
Sheets.

increased due to the increase in income before income taxes and the increase in the effective
income tax rate. The increase in the effective tax rate was primarily due to the complete
utilization of remaining federal, foreign and a significant portion of remaining state net
operating loss carryforwards through the end of 2010, which lowered the income tax provision in
2010.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of March&nbsp;31, 2011, the Company had a remaining valuation allowance of approximately
$10,600,000 against certain deferred tax assets, for which realization cannot be considered more
likely than not at this time. Such deferred tax assets principally relate to tax credit
carryforwards in certain state tax jurisdictions for which sufficient taxable income for
utilization cannot be projected at this time or the credits may expire without being utilized.
Management assesses the need for the valuation allowance on a quarterly basis. If and when
management determines the valuation allowance should be released, the adjustment would result in
a tax benefit in the Consolidated Statements of Operations and may include a portion to be
accounted for through &#147;Additional paid-in capital&#148;, a component of Stockholders&#146; Equity. The
amount of the tax benefit to be recorded in a particular quarter could be material.

Massachusetts corporate excise tax returns, for tax years 2006 and 2007 had been selected for

other income tax audits currently in process.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At March&nbsp;31, 2011, the Company had approximately $1,192,000 of capital expenditure
commitments.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On February&nbsp;22, 2007, the Company announced it had reached an agreement in principle with
Ericsson, Inc., the U.S. affiliate of LM Ericsson, to settle a lawsuit brought by Ericsson
against the Company in California state court. Under the terms of the settlement agreement
entered into on March&nbsp;29, 2007, after a court ordered mediation, the Company paid $50,000,000 to
Ericsson, of which $12,800,000 was reimbursed by&nbsp;the Company&#146;s insurance carriers.
Accordingly, the Company recorded a net loss of $37,200,000 from the litigation &#151; related
settlements in the fourth quarter of 2006. The Company has been seeking further reimbursement
from its insurance carriers. On November&nbsp;14, 2008, a jury in the United States District Court for
the District of Massachusetts found in favor of the Company in a lawsuit against certain of its
insurance carriers with respect to the Ericsson settlement. The jury awarded $17,300,000 in
damages to Vicor, although the verdict is subject to challenge in the trial court and on appeal.
Both parties filed certain motions subsequent to the ruling and, on March&nbsp;2, 2009, the judge in
the case rendered his decision on the subsequent motions, reducing the jury award by $4,000,000.
On March&nbsp;26, 2009, the U.S. District Court, District of Massachusetts (&#147;the Court&#148;) issued its
judgment in the matter, affirming the award of $13,300,000, plus prejudgment interest from the
date of breach on March&nbsp;29, 2007, through March&nbsp;26, 2009, the date of judgment in the amount of
approximately $3,179,000. The insurance carriers have filed their appeal to this total judgment
in the amount of approximately $16,479,000. No final and collectible judgment has been entered by
the Court yet.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On January&nbsp;28, 2011, SynQor, Inc. (&#147;SynQor&#148;) filed a complaint for patent infringement
against Ericsson, Inc. (&#147;Ericsson&#148;), Cisco Systems, Inc. (&#147;Cisco&#148;) and Vicor in U.S. District
Court for the Eastern District of Texas. This immediately followed a complaint filed by the
Company on January&nbsp;26, 2011 in U.S. District Court for the District of Massachusetts, in which
the Company sought a declaratory judgment that its bus converter products do not infringe any
valid claim of certain of SynQor&#146;s U.S. patents, and that the claims of those patents are
invalid. With respect to Vicor, SynQor&#146;s complaint alleges that Vicor&#146;s products, including, but
not limited to, unregulated bus converters used in intermediate bus architecture power supply
systems, infringe certain SynQor patents. SynQor seeks, amongst other items, an injunction
against further infringement and an award of unspecified compensatory and enhanced damages,
interest, costs and attorney
fees. On February&nbsp;8, 2011, SynQor filed a motion for preliminary injunction seeking an order
enjoining Vicor from manufacturing, using, selling, and offering for sale in the United States
and/or importing into the United States certain identified unregulated bus converters, as well as
any other bus converters not significantly different from those products. On February&nbsp;17, 2011,
the Company dismissed its Massachusetts action without prejudice to allow the litigation to
proceed in Texas. An initial hearing has been scheduled for late May&nbsp;2011 in Marshall, Texas.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">Vicor does not believe any of its products, including its unregulated bus converters,
infringe any valid claim of the SynQor patents, either alone or when used in an intermediate bus
architecture implementation. Vicor believes SynQor&#146;s claims lack merit and therefore the Company
plans to vigorously defend itself against SynQor&#146;s patent infringement allegations.

be predicted with certainty, management does not expect any current litigation or claims to have
a material adverse impact on the Company&#146;s financial position or results of operations.

revenues for shipments of V*I Chip products by VJCL in the V*I Chip segment, along with an
allocation of certain VJCL operating expenses from the BBU to the V*I Chip segment. Previously,
all VJCL operating activity had been included in the BBU segment. The segment information for the

    <TD>During the fourth quarter of 2010, the Company completed a recapitalization of V*I
Chip. The impact of the recapitalization on V*I Chip was to eliminate its intercompany
payable to BBU of approximately $172,100,000 and institute capital accounts totaling
$50,000,000 as of December&nbsp;31, 2010. There was no impact on the consolidated financial
statements as a result of this recapitalization.</TD>

    <TD>The elimination for net revenues is principally related to inter-segment revenues of
Picor to BBU and V*I Chip and for inter-segment revenues of V*I Chip to BBU. The
elimination for total assets is principally related to inter-segment accounts
receivable due to BBU for the funding of V*I Chip operations and for the purchase of
equipment for both V*I Chip and Picor.</TD>

forward-looking statements. Forward-looking statements also include statements regarding the
derivation of a portion of the Company&#146;s sales in each quarter from orders booked in the same
quarter, the Company&#146;s plans to invest in research and development and manufacturing equipment, the
Company&#146;s belief regarding market risk being mitigated because of limited foreign exchange
fluctuation exposure, the Company&#146;s continued success depending in part on its ability to attract
and retain qualified personnel, the Company&#146;s belief that cash generated from operations and the
total of its cash and cash equivalents and short-term investments will be sufficient for the
foreseeable future, the Company&#146;s intention regarding protecting its rights under its patents and
the Company&#146;s expectation that no current litigation or claims will have a material adverse impact
on its financial position or results of operations. These statements are based upon the Company&#146;s
current expectations and estimates as to the prospective events and circumstances which may or may
not be within the Company&#146;s control and as to which there can be no assurance. Actual results
could differ materially from those projected in the forward-looking statements as a result of
various factors, including our ability to develop and market new products and technologies cost
effectively, to leverage design wins into increased product sales, to continue to make progress
with key customers and prospects, to decrease manufacturing costs, to enter into licensing
agreements that amplify the market opportunity and accelerate market penetration, to realize
significant royalties under license agreements, to achieve a sustainable increased bookings rate
over a longer period, to hire key personnel and to continue to build our three business units, to
successfully enforce our intellectual property rights, to successfully defend outstanding
litigation, to successfully leverage the V<B>*</B>I Chips in standard products to promote market
acceptance of Factorized Power Architecture, to develop or maintain an effective system of internal
controls, to obtain required financial information for certain investments on a timely basis, and
factors impacting the Company&#146;s various end markets, the impact of write-downs in the value of
assets, the effects of equity accounting with respect to certain affiliates, the failure of auction
rate securities to sell at their reset dates as well as those factors described in the risk
factors set forth in the Company&#146;s Annual Report on Form 10-K for the year ended December&nbsp;31, 2010,

be exhaustive. Therefore, the information contained in this report should be read together with
other reports and documents that the Company files with the Securities and Exchange Commission from
time to time, including Forms 10-Q, 8-K and 10-K, which may supplement, modify, supersede or update

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Revenues for the first quarter increased by 36.3% to $70,455,000, compared to $51,709,000 for
the corresponding period a year ago, but decreased by 3.5% on a sequential basis from $72,975,000
for the fourth quarter of 2010. Gross margin increased to $30,454,000 for the first quarter of
2011, compared to $23,324,000 for the corresponding period a year ago, but decreased on a
sequential basis from $32,984,000 for the fourth quarter of 2010. Gross margin, as a percentage of
revenue, decreased to 43.2% for the first quarter of 2011 compared to 45.1% for the first quarter
of 2010 and decreased on a sequential basis from 45.2% for the fourth quarter of 2010. Net income
attributable to Vicor Corporation for the first quarter was $4,018,000, or $0.10 per diluted share,
compared to net income attributable to Vicor Corporation of $1,952,000, or $0.05 per diluted share,
for the corresponding period a year ago and net income attributable to Vicor Corporation of
$10,807,000, or $0.26 per diluted share, for the fourth quarter of 2010.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The book-to-bill ratio, calculated by the dollar amount of orders placed with scheduled
delivery dates within one year divided by the net revenues in the respective period, was 0.94:1 for
the first quarter of 2011, compared to 0.66:1 for the fourth quarter of 2010. Backlog,
representing the total of purchase orders received for which product has not yet been shipped, was
$74,757,000 at the end of the first quarter of 2011, as compared to $78,876,000 at the end of the
fourth quarter of 2010.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Operating expenses for the three months ended March&nbsp;31, 2011 increased $3,286,000, or 15.8%,
to $24,034,000 from $20,748,000 in 2010, principally due to an increase in selling, general and
administrative expenses of $2,300,000, and research and development expenses of $986,000. The key
increases in selling, general and administrative expenses were in compensation expense of
$1,029,000, legal expense of $871,000, and commissions expense of $318,000, partially offset by a
decrease in audit and tax fees of $75,000. The key increases in research and development expenses
were in compensation expense of $705,000, deferred costs of $80,000, depreciation and amortization
of $60,000, project materials of $58,000, and computer expense of $36,000, partially offset by a
decrease in outside services of $87,000.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Other income (expense), net for the three months ended March&nbsp;31, 2011 decreased $265,000 to
$(198,000) from $67,000 in the corresponding period in 2010. The primary reasons for the decrease
were an increase in foreign currency losses of $239,000 and a decrease in interest income of
$71,000, partially offset by an increase in credit gain on available-for-sale securities of
$50,000.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;For the three months ended March&nbsp;31, 2011, depreciation and amortization was $2,628,000 and
capital additions were $2,973,000, compared to $2,432,000 and $2,429,000, respectively, for the
first three months of 2010.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Inventories increased by approximately $121,000 or 0.3% to $35,610,000 as compared with
$35,489,000 at December&nbsp;31, 2010. This increase was primarily attributed to an increase in BBU
inventories of $478,000, partially offset by a decrease in V*I Chip and Picor inventories of
approximately $320,000, and $37,000, respectively.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Orders during the three months ending March&nbsp;31, 2011 increased by 37.1% compared with the
fourth quarter of 2010. This increase was caused by increases during the period in BBU, V*I Chip,
and Picor orders of 21.5%, 118.7% and 212.7%, respectively. The consolidated book to bill ratio
for the three months ended March&nbsp;31, 2011, was 0.94:1, as compared to 1.39:1 for the corresponding
period a year ago, and 0.66:1 for the fourth quarter of 2010. The quarterly book-to-bill ratio has
been volatile and management believes that the ratio is not always an accurate indicator of the
amount or timing of future revenue.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Gross margin for the first quarter of 2011 increased $7,130,000, or 30.6%, to $30,454,000 from
$23,324,000 in the first quarter of 2010. Gross margin, as a percentage of net revenues, decreased
to 43.2% from 45.1% as a percentage of net revenues. The increase in gross margin dollars was
primarily due to the increase in net revenues. The decrease in gross margin percentage was
primarily due to a shift in product mix to a higher proportion of lower margin V*I Chip products,
partially offset by lower average unit costs of both BBU and V*I Chip products, in the first
quarter of 2011 compared to 2010. In addition, during the first quarter of 2011, the Company
increased inventory and warranty reserves by approximately $743,000 through charges to cost of
revenues for inventory to be scrapped and for expected future replacements of certain products
under warranty, both of which were manufactured with a component that exhibited a higher than
expected failure rate.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Selling, general and administrative expenses were $14,180,000 for the quarter ended March&nbsp;31,
2011, an increase of $2,300,000, or 19.4%, as compared to $11,880,000 for the same period in 2010.
Selling, general and administrative expenses as a percentage of net revenues, decreased to 20.1%
from 23.0% for the same period in 2010, primarily due to the increase in net revenues.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;s exposure to market risk for fluctuations in foreign currency exchange rates
relates primarily to the operations of VJCL. The functional currency of the Company&#146;s subsidiaries
in Europe and Hong Kong is the U.S. dollar. The decrease in interest income is due to lower
average balances on the Company&#146;s short and long-term investments as well as a decrease in interest
rates. The estimated credit gains (losses)&nbsp;on the Company&#146;s other auction rate securities result
from the change in the estimated fair value of these investments at March&nbsp;31, 2011 and March&nbsp;31,
2010, compared to December&nbsp;31, 2010 and December&nbsp;31, 2009, respectively.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;For the three months ended March&nbsp;31, 2011 compared to 2010, the provision for income taxes
increased due to the increase in income before income taxes and the increase in the effective
income tax rate. The increase in the effective tax rate was primarily due to the complete
utilization of remaining federal, foreign and a significant portion of remaining state, net
operating loss carryforwards through the end of 2010, which lowered the income tax provision in
2010.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Net income of noncontrolling interest increased $98,000 to $151,000 in the first quarter of
2011 from $53,000 for the same period in 2010. This was due to higher net income at certain
entities in which the Company holds a noncontrolling interest.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Basic and diluted income per share attributable to Vicor Corporation was $0.10 for the first
quarter of 2011 compared to $0.05 for the first quarter of 2010.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><U>Liquidity and Capital Resources</U>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At March&nbsp;31, 2011, the Company had $56,400,000 in cash and cash equivalents. The ratio of
current assets to current liabilities was 5.3:1 as of March&nbsp;31, 2011, and 5.6:1 as of December&nbsp;31,
2010. Working capital increased $5,316,000 to $110,770,000 as of March&nbsp;31, 2011, from $105,454,000
as of December&nbsp;31, 2010. The primary factors affecting the working capital increase were increases
in cash and cash equivalents of $7,121,000, accounts receivable of $971,000, deferred tax assets of
$335,000 and inventories of $121,000, partially offset by increases in accrued expenses of
$1,098,000, accounts payable of $795,000, accrued compensation and benefits of $717,000, and income
taxes payable of $667,000. The primary source of cash for the three months ended March&nbsp;31, 2011,
was $9,906,000 from operating activities. The primary use of cash for the three months ended March
31, 2011 was $2,973,000 for the purchase of equipment.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of March&nbsp;31, 2011, the Company held $18,975,000 of auction rate securities at par value
classified as long-term investments. Please see Note 2 of the Company&#146;s Condensed Consolidated
Financial Statements for a discussion of the securities and the Company&#146;s accounting treatment
thereof.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In November&nbsp;2000, the Board of Directors of the Company authorized the repurchase of up to
$30,000,000 of the Company&#146;s Common Stock (the &#147;November&nbsp;2000 Plan&#148;). The November&nbsp;2000 Plan
authorizes the Company to make such repurchases from time to time in the open market or through
privately negotiated transactions. The timing and amounts of stock repurchases are at the
discretion of management based on its view of economic and financial market conditions. The Company
did not repurchase shares of Common Stock during the three months ended March&nbsp;31, 2011. As of
March&nbsp;31, 2011, the Company had approximately $8,541,000 remaining under the November&nbsp;2000 Plan.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;s primary liquidity needs are for making continuing investments in manufacturing
equipment, particularly equipment to increase capacity for our V*I Chip products. The Company
believes cash generated from operations and the total of its cash and cash equivalents will be
sufficient to fund planned operations and capital equipment purchases for the foreseeable future.
The Company had approximately $1,192,000 of capital expenditure commitments, principally for
manufacturing equipment, as of March&nbsp;31, 2011.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company is exposed to a variety of market risks, including changes in interest rates
affecting the return on its cash and cash equivalents and fluctuations in foreign currency exchange
rates. As the Company&#146;s cash and cash equivalents consist principally of money market securities,
which are short-term in nature, the Company believes its exposure to market risk on interest rate
fluctuations for these investments is not significant. The Company&#146;s long-term investments consist
mainly of municipal and corporate debt securities, of which the Failed Auction Securities represent
a significant portion. While the Failed Auction Securities are all highly rated investments,
generally with AAA/Aaa ratings, continued failure to sell at their reset dates could negatively
impact the carrying value of the investments, in turn leading to impairment charges in future
periods. Changes in the fair value of the Failed Auction Securities attributable to credit loss are
recorded through earnings, with the remainder of any change recorded in &#147;Accumulated other
comprehensive loss&#148;, a component of Stockholders&#146; Equity. Should a decline in the value of the
Failed Auction Securities be other than temporary, the losses would be recorded in &#147;Other income
(expense), net.&#148; The Company does not believe there was an &#147;other-than-temporary&#148; decline in value
in these securities as of March&nbsp;31, 2011.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;s exposure to market risk for fluctuations in foreign currency exchange rates
relates primarily to the operations of VJCL and changes in the dollar/yen exchange rate, as the
functional currency of the Company&#146;s subsidiaries in Europe and Hong Kong is the U.S. dollar.
Therefore, the Company believes market risk is mitigated since these operations are not materially
exposed to foreign exchange fluctuations.

the participation of the Company&#146;s Chief Executive Officer (&#147;CEO&#148;) and Chief Financial Officer
(&#147;CFO&#148;), conducted an evaluation of the effectiveness of the Company&#146;s disclosure controls and
procedures, as of the end of the last fiscal quarter (i.e., March&nbsp;31, 2011). In designing and
evaluating the Company&#146;s disclosure controls and procedures, the Company and its management
recognize that any controls and procedures, no matter how well designed and operated, can provide
only reasonable assurance of achieving the desired control objectives, and management necessarily
was required to apply its judgment in evaluating and implementing possible controls and procedures.
Based upon that evaluation, management, including the Company&#146;s CEO and CFO, has concluded the
Company&#146;s disclosure controls and procedures as of March&nbsp;31, 2011, were reasonably effective to
ensure that information required to be disclosed by the Company in the reports 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&#146;s rules and forms. Management intends to
continue to review and document the Company&#146;s disclosure controls and procedures, including
internal controls over financial reporting, and may from time to time make changes to the
disclosure controls and procedures to enhance their effectiveness and to ensure that the Company&#146;s
systems evolve with its business.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A control system, no matter how well designed and operated, can provide only reasonable, not
absolute, assurance that the control system&#146;s objectives will be met. Accordingly, management,
including the CEO and CFO, recognizes the Company&#146;s disclosure controls or its 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 that 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 that 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&#146;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.
