1. Basis of Presentation

     The accompanying unaudited condensed consolidated financial statements 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. 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, 2010, are not necessarily indicative of the results that may be expected for any other interim period or the year ending December 31, 2010. The balance sheet at December 31, 2009, 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, 2009, (File No. 0-18277) filed by the Company with the Securities and Exchange Commission.

2. Short-Term and Long-Term Investments

     The Company’s principal sources of liquidity are its existing balances of cash, cash equivalents and short-term investments, as well as cash generated from operations. Consistent with the Company’s investment policy guidelines, the Company can and has historically invested its substantial cash balances in demand deposit accounts, money market funds and auction rate securities meeting certain quality criteria. All of the Company’s investments are subject to credit, liquidity, market, and interest rate risk.

     The Company’s short-term and long-term investments are classified as either trading or available-for-sale securities. 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 “Accumulated other comprehensive loss”, a component of Stockholders’ 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 credit default risk probabilities and changes in credit ratings as significant inputs, among other factors. Trading securities are recorded at fair value, with unrealized gains and losses recorded through the Condensed Consolidated Statements of Operations each reporting period. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization, along with interest and realized gains and losses, are included in “Other income, net” 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.

     The following is a summary of available-for-sale securities (in thousands):

						Gross				Gross				Estimated

(unaudited)

     As of June 30, 2010, the Company held $27,900,000 of auction rate securities at par value, of which $19,300,000 are held by a broker-dealer affiliate of Bank of America (the “BofA ARS”) and $8,600,000 were held by a broker-dealer affiliate of UBS AG (the “UBS ARS”). 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 days. The auction rate securities held by the Company traded at par prior to February 2008 and are callable at par at the option of the issuer. On June 30, 2010, the majority of the auction rate 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.

     Until February 2008, the auction rate securities market was liquid, as the investment banks conducting the periodic “Dutch auctions” 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 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) 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) the interest rate on the security generally resets to an interest rate set forth in each security’s indenture.

     As of June 30, 2010, the Company held auction rate securities that had experienced failed auctions totaling $27,900,000 at par value (the “Failed Auction Securities”), of which $50,000 of the BofA ARS were redeemed by the issuer at par subsequent to June 30, 2010. The Company’s remaining $8,600,000 of UBS ARS were purchased by UBS at par on June 30, 2010, pursuant to an earlier rights agreement with UBS, with a trade settlement date of July 1, 2010. Accordingly, the UBS ARS were recorded at par and classified as short-term investments as of June 30, 2010.

     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 June 30, 2010, the Company has continued to receive interest payments on the Failed Auction Securities in accordance with the terms of their respective indentures. Management believes the Company ultimately should be able to liquidate all of its auction rate security investments 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 June 30, 2010, except for the $8,650,000 in redemptions, noted above, which were reclassified to short-term.

     Based on the fair value measurements described in Note 3, the fair value of the BofA ARS on June 30, 2010, with a par value of $19,300,000, was estimated by the Company to be approximately $16,408,000, a decrease in fair value of $260,000, net of $400,000 of redemptions from December 31, 2009. The gross unrealized loss of $2,892,000 on the BofA ARS consists of two types of estimated loss: an aggregate credit loss of $506,000 and an aggregate temporary impairment of $2,386,000. For the six months ended June 30, 2010, the aggregate credit loss on the BofA ARS increased by a net amount of $42,000, which was recorded in “Net impairment losses recognized in earnings” 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).

VICOR CORPORATION

Notes to Condensed Consolidated Financial Statements

     The following table sets forth activity related to the estimated credit loss on the BofA ARS recognized in earnings on available-for-sale auction rate securities held by the Company for the three and six months ended June 30, 2010 (in thousands):

		Three Months Ended												Six Months Ended
		June 30,												June 30,
		2010												2010
Balance at the beginning of the period						$	507											$	464
Reductions for securities sold during the period							—												(12	)
Reduction for accretion of subsequent credit loss recovery
Additions for the amount related to credit (gain) loss for which other-than-temporary impairment was not previously recognized							(1	)											54
Balance at the end of the period						$	506											$	506

     For the second quarter, the Company decreased the temporary impairment recorded in “Accumulated other comprehensive (loss) income” in the Condensed Consolidated Balance Sheet by $123,000 to reflect an increase in the estimated value of the BofA ARS.

     At this time, the Company has no intent to sell any of the impaired BofA ARS and does not believe that it is more likely than not that 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.

     Based on the Company’s ability to access cash and other short-term investments 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’s ability to execute its current operating plan.

3. 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.

     The Company uses the fair value option for certain financial assets, which allows an entity the irrevocable option to elect fair value for the initial and subsequent measurement for specified financial assets and liabilities on a case-by-case basis.

     As of June 30, 2010, there was insufficient observable auction rate security market information available to determine the fair value of the Failed Auction Securities and the ARS Right using Level 1 or Level 2 inputs. As such, the Company’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’s interest rate was set). Management utilized a probability weighted discounted cash flow (“DCF”) model to determine the estimated fair value of these securities as of June 30, 2010. 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% for AAA rated securities, the rate of return required by investors to own these securities in the current environment, which we estimate 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.

(2) Options to purchase 368,452 and 780,148 shares of Common Stock for the three months ended June 30, 2010 and June 30, 2009, respectively, were not included in the computation of diluted income per share because the options’ exercise prices were greater than the average market price of the Common Stock and, therefore, the effect would be antidilutive. Options to purchase 512,859 shares of Common Stock for the six months ended June 30, 2010 were not included in the computation of diluted income per share because the options’ exercise prices were greater than the average market price of the Common Stock and, therefore, the effect would be antidilutive. Options to purchase 884,875 shares of Common Stock were outstanding for the six months ended June 30, 2009, but were not included in the calculation of net loss per share as the effect would have been antidilutive.

6. Inventories

     Inventories are valued at the lower of cost (determined using the first-in, first-out method) or net realizable value. The Company provides reserves for inventories estimated to be excess, obsolete or unmarketable. The Company’s estimation process for assessing net realizable value is based upon its known backlog, projected future demand and expected market conditions. If the Company’s estimated demand and / or market expectation were to change or if product sales were to decline, the Company’s estimation process may cause larger inventory reserves to be recorded, resulting in larger charges to cost of revenues.

7. Other Investments

     The Company’s gross investment in non-voting convertible preferred stock of Great Wall Semiconductor Corporation (“GWS”) totaled $5,000,000 as of June 30, 2010, and December 31, 2009, 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 (“CEO”), 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, and the Company purchases certain components from GWS. Purchases from GWS totaled approximately $1,333,000 and $491,000 for the six months ended June 30, 2010, and 2009, respectively.

     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’s assessment were that the CEO of GWS has: (i) the power to direct the activities of GWS that most significantly impact its economic performance, and (ii) has an obligation to absorb losses or the right to receive benefits from GWS, respectively, that could potentially be significant to GWS.

     There was no allocation of equity method income (loss) for the six months ended June 30, 2010 and 2009, as GWS incurred a net loss in each period. Due to an adjustment to the investment for a decline in value judged to be other than temporary during the fourth quarter of 2008, the amounts included in “Other assets” in the accompanying Condensed Consolidated Balance Sheets related to the net GWS investment were zero as of June 30, 2010, and December 31, 2009.

8. Severance Charges

     During 2009, the Company initiated workforce reductions and pre-tax charges were recorded for the cost of severance and other employee-related costs involving cash payments during 2009 and 2010 based on each employee’s respective length of service. Total severance charges of $4,099,000 were recorded in 2009, of which $3,957,000 was recorded through the first six months of 2009. These charges were recorded as “Severance charges” in the Condensed Consolidated Statement of Operations. The related liability is presented as “Accrued severance charges” in the Condensed Consolidated Balance Sheets.

9. Product Warranties

     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’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 “Accrued expenses” in the accompanying Condensed Consolidated Balance Sheets.

     Product warranty activity for the three and six months ended June 30, were as follows (in thousands):

		Three Months Ended																Six Months Ended
		June 30,																June 30,
		2010								2009								2010								2009
Balance at the beginning of the period						$	720							$	904							$	772							$	896

Balance at the end of the period						$	1,038							$	899							$	1,038							$	899

10. Income Taxes

     In 2010, the tax provision is based on the estimated annual effective tax rate for 2010, which includes estimated federal, state and foreign income taxes on the Company’s projected annual pre-tax income and estimated federal and state income taxes for certain minority-owned subsidiaries that are not part of the Company’s consolidated income tax returns, offset by the expected utilization of federal and foreign net operating loss carryforwards. The tax provision in 2009 provided for estimated income taxes due in various state and international taxing jurisdictions for which losses incurred by the Company cannot be offset, and for estimated federal and state income taxes for certain minority-owned subsidiaries that are not part of the Company’s consolidated income tax returns. The 2010 and 2009 tax provisions also include discrete items, principally expense for net increases in state taxes and accrued interest for potential liabilities.

     The Company recorded income tax expense for the three and six months ended June 30, 2009, based on a discrete-period computation because it believed a reliable estimate of its effective annual tax rate could not be made at that time. This was due to the difficulty in accurately forecasting the expected ordinary income (loss) for the year and that small variations in any forecast would have caused wide variability in the estimated tax rate. That variability in the estimated effective annual tax rate is more limited when projecting annual pre-tax income for 2010 and, thus, the Company utilized the effective tax rate method in calculating the tax provision for the three and six months ended June 30, 2010.

VICOR CORPORATION

(unaudited)

     The provision for income taxes and the effective income tax rate for the three and six months ended June 30, were as follows (in thousands):

		Three Months Ended								Six Months Ended
		June 30								June 30
		2010				2009				2010				2009
Provision for income taxes		$	319			$	544			$	957			$	972
Effective income tax rate			6.3%				23.6%				12.4%				167.9%

     The decrease in the provision for income taxes and effective income tax rates for the three and six months ended June 30, 2010 compared to 2009 was principally due to the impact of using the effective tax rate method in 2010 versus a discrete-period computation in 2009 and lower tax expense in 2010 for one of the minority-owned subsidiaries that is not part of the Company’s consolidated income tax returns.

     The Company continues to maintain a valuation allowance against a significant portion of its deferred tax assets. Management assesses the need for the valuation allowance on a quarterly basis. If and when management determines the valuation allowance should be released, in light of the Company’s continued positive operating performance and other factors, the adjustment would result in a tax benefit in the Consolidated Statements of Operations and may include a portion to be accounted for through “Additional paid-in capital”, a component of Stockholders’ Equity. The amount of the tax benefit to be recorded in a particular quarter could be material.

     In January 2010, the Company received notices from the Commonwealth of Massachusetts and the State of New York that its Massachusetts corporate excise tax returns and New York corporate tax returns, respectively, for tax years 2006 and 2007 had been selected for audit. In April 2010, Vicor Japan Company, Ltd. received notice from the Regional Taxation Bureau that its corporate tax and tax returns, respectively, for tax years from 2007 to 2009 have been selected for audit. The audits with the State of New York and the Regional Taxation Bureau of Japan were both settled in the second quarter for immaterial amounts. While the Massachusetts audit was underway as of June 30, 2010, there are no other income tax audits currently in process.

Unrealized gains (losses) (net of tax) on available-for-sale securities			119				1,342				(254	)			1,176
Comprehensive income			5,001				3,150				6,666				688

Comprehensive income (loss) attributable to Vicor Corporation		$	4,988			$	2,735			$	6,596			$	(125	)

12. Commitments and Contingencies

     At June 30, 2010, the Company had approximately $1,789,000 of capital expenditure commitments.

     On February 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 29, 2007, after a court ordered mediation, the Company paid $50,000,000 to Ericsson, of which $12,800,000 was reimbursed by the Company’s insurance carriers. Accordingly, the Company recorded a net loss of $37,200,000 from the litigation-related settlements in the fourth quarter of 2006. The Company has been seeking further reimbursement from its insurance carriers. On November 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 2, 2009, the judge in the case rendered his decision on the subsequent motions, reducing the jury award by $4,000,000. On March 26, 2009, the U.S. District Court, District of Massachusetts issued its judgment in the matter, affirming the award of $13,300,000, plus prejudgment interest from the date of breach on March 29, 2007, through March 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.

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

13. Segment Information

     The Company has organized its business segments according to its key product lines. The Brick Business Unit segment (“BBU”) designs, develops, manufactures and markets the Company’s modular power converters and configurable products, and also includes the operations of the Company’s Westcor division, the six entities comprising Vicor Custom Power, and Vicor Japan Company, Ltd. (“VJCL”). V*I Chip designs, develops, manufactures and markets the Company’s Factorized Power Architecture

(“FPA”) products. Picor designs, develops, manufactures and markets power management integrated circuits and related products for use in a variety of power system applications. Picor develops these products to be sold as part of Vicor’s products or to third parties for separate applications.

     The following table provides significant segment financial data as of and for the three months ended June 30, 2010 and 2009 (in thousands):

		BBU				V*I Chip				Picor				Corporate				Eliminations				Total
2010:
Net revenues		$	51,857			$	6,024			$	2,873			$	-			$	(3,377	)		$	57,377

Depreciation and amortization			1,391				728				96				394				-				2,609

     The following table provides significant segment financial data as of and for the six months ended June 30, 2010 and 2009 (in thousands):

		BBU				V*I Chip				Picor				Corporate				Eliminations				Total
2010:
Net revenues		$	99,034			$	11,304			$	4,683			$	-			$	(5,935	)		$	109,086
Income (loss) from operations			21,868				(13,247	)			(987	)			(283	)			(134	)			7,217
Total assets			213,636				23,358				8,564				97,479				(149,814	)			193,223
Depreciation and amortization			2,310				1,688				213				746				-				4,957
2009:
Net revenues		$	96,382			$	6,962			$	2,899			$	-			$	(5,168	)		$	101,075
Income (loss) from operations			13,833				(11,873	)			(2,299	)			(339	)			946				268
Total assets			187,022				14,330				9,244				95,667				(131,677	)			174,586
Depreciation and amortization			2,808				1,463				188				775				-				5,234

     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 receivables due to BBU for the funding of V*I Chip operations and for the purchase of equipment for both V*I Chip and Picor.

     For the period ended June 30, 2009, the Company restated its total assets by segment for the BBU (decrease of $4,917,000, or 2.8% of total assets), Corporate (increase of $1,655,000, or 0.9% of total assets) and Eliminations (increase of $3,262,000, or 1.9% of total assets) due to an error in the calculation of this segment data. The error did not have any impact on the condensed consolidated financial statements for the period ending June 30, 2009, and management does not believe the error is material to the segment information taken as a whole.

14. Impact of Recently Issued Accounting Standards

     Effective January 1, 2010, the Company adopted new accounting guidance related to the Consolidation of Variable Interest Entities. The new accounting standard replaces the quantitative-based risks and rewards calculation for determining which enterprise, if any, has a controlling financial interest in a variable interest entity with an approach focused on identifying which enterprise has the power to direct the activities of a variable interest entity that most significantly impact the entity’s economic performance and (1) the obligation to absorb losses of the entity or (2) the right to receive benefits from the entity. The new standard also provides additional reconsideration events for determining whether an entity is a variable interest entity and requirements for ongoing assessments of whether an enterprise is the primary beneficiary of a variable interest entity. The adoption of this new accounting guidance did not have a material effect on the Company’s financial position or results of operations.

     Effective January 1, 2010, the Company adopted new accounting guidance on fair value measurements and disclosures. The new guidance requires more robust disclosures about (1) the different classes of assets and liabilities measured at fair value, (2) the valuation techniques and inputs used, (3) the activity in Level 3 fair value measurements, and (4) the transfers between Levels 1, 2, and 3. The adoption of this new accounting guidance did not have a material effect on the Company’s financial position or results of operations.

15. Dividends

     On June 28, 2010, the Company announced that its Board of Directors had approved a cash dividend of $.30 per share of the Company’s stock. The aggregate dividend of approximately $12,506,000 is payable on July 30, 2010 to shareholders of record at the close of business on July 16, 2010.

     Dividends are declared at the discretion of the Company’s Board of Directors and depend on actual cash from operations, the Company’s financial condition and capital requirements and any other factors the Company’s Board of Directors may consider relevant.

     During the second quarter ended June 30, 2010, a subsidiary paid a dividend of $1,650,000, of which $297,000 was paid to an outside shareholder and accounted for as a reduction in noncontrolling interests.

Management’s Discussion and Analysis of
Financial Condition and Results of Operation
June 30, 2010

     Revenues for the second quarter increased by 13.3% to $57,377,000, compared to $50,627,000 for the corresponding period a year ago, and increased 11.0% on a sequential basis from $51,709,000 for the first quarter of 2010. Gross margin increased to $25,739,000 for the second quarter of 2010, compared to $22,598,000 for the corresponding period a year ago, and increased on a sequential basis from $23,324,000 for the first quarter of 2010. Gross margin, as a percentage of revenue, increased to 44.9% for the second quarter of 2010 compared to 44.6% for the second quarter of 2009, but decreased on a sequential basis from 45.1% for the first quarter of 2010. Net income (loss) attributable to Vicor Corporation for the second quarter was $4,747,000, or $0.11 per diluted share, compared to net income (loss) attributable to Vicor Corporation of $1,341,000, or $0.03 per diluted share, for the corresponding period a year ago and net income (loss) attributable to Vicor Corporation of $1,952,000, or $0.05 per diluted share, for the first quarter of 2010.

     Revenues for the six months ended June 30, 2010 increased by 7.9% to $109,086,000, compared to $101,075,000 for the corresponding period a year ago. Gross margin increased to $49,063,000 for the six months ended June 30, 2010, compared to $44,429,000 for the corresponding period a year ago. Gross margin, as a percentage of revenue, increased to 45.0% for the six months ended June 30, 2010 compared to 44.0% for the corresponding period a year ago. Net income (loss) attributable to Vicor Corporation for the six months ended June 30, 2010 was $6,699,000, or $0.16 per diluted share, compared to net income (loss) attributable to Vicor Corporation of $(1,202,000), or $(0.03) per diluted share, for the corresponding period a year ago. The net loss for the six months ended June 30, 2009 was primarily due to an aggregate pre-tax charge of $3,957,000 for the cost of severance and other employee-related costs in connection with the Company’s workforce reductions implemented in the first and second quarters of 2009.

     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 1.43:1 for the second quarter of 2010, compared to 1.39:1 for the first quarter of 2010. The book-to-bill ratio for the six months ended June 30, 2010 was 1.41:1 compared to 1.18:1 for the six months ended December 31, 2009. Backlog, representing the total of purchase orders received for which product has not yet been shipped, was $103,227,000 at the end of the second quarter of 2010, as compared to $78,407,000 at the end of the first quarter of 2010.

     Operating expenses for the three months ended June 30, 2010 increased $609,000, or 3.0%, to $21,098,000 from $20,489,000 in 2009, principally due to an increase in research and development expenses of $1,426,000, partially offset by a pre-tax charge of $859,000 recorded in the second quarter of 2009 for severance and other employee-related costs in connection with a workforce reduction implemented during that quarter. The key increases in research and development expenses were compensation expenses of $498,000, project materials of $294,000, deferred costs of $166,000 and outside services of $160,000.

     Operating expenses for the six months ended June 30, 2010 decreased $2,315,000, or 5.2%, to $41,846,000 from $44,161,000 in 2009, principally due to a pre-tax charge of $3,957,000 recorded for the six months ended June 30, 2009 for severance and other employee-related costs in connection with workforce reduction implemented during the six months ended June 30, 2009 and a decrease in selling, general and administrative expenses of $901,000, partially offset by an increase in research and development expenses of $2,543,000.

VICOR CORPORATION

Management’s Discussion and Analysis of
Financial Condition and Results of Operation
June 30, 2010

     For the six months ended June 30, 2010, depreciation and amortization was $4,957,000 and capital additions were $4,814,000, compared to $5,234,000 and $2,749,000, respectively, for the first six months of 2009.

     Inventories increased by approximately $4,329,000 or 20.3% to $25,686,000 as compared with $21,357,000 at December 31, 2009 in order to meet the increase in demand. The increase was primarily attributed to increases in BBU and V*I Chip’s inventories of approximately $2,142,000 and $1,979,000, respectively.

Critical Accounting Policies and Estimates

     Please refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2009, for a complete summary of the critical accounting policies and estimates.

Three months ended June 30, 2010, compared to three months ended June 30, 2009

     Net revenues for the second quarter of June 30, 2010, were $57,377,000, an increase of $6,750,000 or 13.3%, as compared to $50,627,000 for the same period a year ago, and an increase of 11.0% on a sequential basis from the first quarter of 2010.

     The components of revenue were as follows (dollars in thousands):

		Three Months Ended
		June 30,								Increase (decrease)
		2010				2009				$				%
BBU		$	51,857			$	47,621			$	4,236				8.9	%
V*I Chip			4,322				2,431				1,891				77.8	%
Picor			1,198				575				623				108.3	%
Total		$	57,377			$	50,627			$	6,750				13.3	%

     The increased revenues in each of the three business units reflects increases in bookings over the last several quarters. Orders during the three months ended June 30, 2010 increased by 14.8% compared with the first quarter of 2010. This increase was caused by increases during the period in BBU and Picor orders of 19.6% and 102.4%, respectively, offset by a decrease in V*I Chip orders of 19.5%. The consolidated book to bill ratio for the three months ending June 30, 2010, was 1.43:1, as compared to 0.79:1 for the corresponding period a year ago, and 1.39:1 for the first quarter of 2010. The quarterly book-to-bill ratio has been volatile and management believes the ratio is not always an accurate indicator of the amount or timing of future revenue.

     Gross margin for the second quarter of 2010 increased $3,141,000, or 13.9%, to $25,739,000 from $22,598,000 in the second quarter of 2009. Gross margin, as a percentage of net revenues, increased to 44.9% from 44.6% as a percentage of net revenues. The primary component of the increase in gross margin dollars and percentage was the increase in net revenues and lower brick production costs.

     Selling, general and administrative expenses were $12,061,000 for the quarter ended June 30, 2010, an increase of $42,000, or 0.3%, as compared to $12,019,000 for the same period in 2009. Selling, general and administrative expenses as a percentage of net revenues, decreased to 21.0% from 23.7% for the same period in 2009, primarily due to the increase in net revenues.

VICOR CORPORATION

Management’s Discussion and Analysis of
Financial Condition and Results of Operation
June 30, 2010

     The unrealized gains (losses) and estimated credit loss on the Company’s auction rate securities and securities rights result from the change in the estimated fair value of these investments during the quarter ended June 30, 2010. The decrease in interest income is due to lower average balances on the Company’s short and long-term investments as well as a decrease in interest rates. The Company’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’s subsidiaries in Europe and Hong Kong is the U.S. dollar.

     Income (loss) before income taxes was $5,066,000 for the second quarter of 2010 compared to $2,302,000 for the same period in 2009.

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

		Three Months Ended
		June 30,
		2010				2009
Provision for income taxes		$	319			$	544
Effective income tax rate			6.3%				23.6%

     The decrease in the provision for income taxes and the effective income tax rate for the three months ended June 30, 2010, compared to 2009, was principally due to the impact of using an effective tax rate method in 2010 versus a discrete-period computation in 2009 and lower tax expense in 2010 for one of the minority-owned subsidiaries that is not part of the Company’s consolidated income tax returns.

     The Company continues to maintain a valuation allowance against a significant portion of its deferred tax assets. Management assesses the need for the valuation allowance on a quarterly basis. If and when management determines the valuation allowance should be released, in light of the Company’s continued positive operating performance and other factors, the adjustment would result in a tax benefit in the Consolidated Statements of Operations and may include a portion to be accounted for through “Additional paid-in capital”, a component of Stockholders’ Equity. The amount of the tax benefit to be recorded in a particular quarter could be material.

     Net income of noncontrolling interest decreased $417,000 to zero in the second quarter of 2010. This was due to lower net income at certain entities in which the Company holds a noncontrolling interest.

     Basic and diluted income (loss) per share attributable to Vicor Corporation was $0.11 for the second quarter of 2010 compared to $0.03 for the second quarter of 2009.

Six months ended June 30, 2010 compared to Six months ended June 30, 2009

     Net revenues for the six months of 2010 were $109,086,000, an increase of $8,011,000 or 7.9%, as compared to $101,075,000, for the same period a year ago.

Total		$	109,086			$	101,075			$	8,011				7.9	%

     The increased revenues in each of the three business units reflects increases in bookings over the last several quarters. Orders during the six months ending June 30, 2010 increased by 35.1% compared with the second half of 2009. This increase was caused by increases in BBU, V*I Chip, and Picor orders of 20.7%, 193.4%, and 401.2%, respectively. The consolidated book to bill ratio for the six months ending June 30, 2010, was 1.41:1, as compared to 0.89:1 for the corresponding period a year ago, and 1.18:1 for the second half of 2009. The quarterly book-to-bill ratio has been volatile, and management believes the ratio is not always an accurate indicator of the amount or timing of future revenue.

     Gross margin for the first six months of 2010 increased $4,634,000, or 10.4%, to $49,063,000 from $44,429,000 compared to the same period a year ago. Gross margin, as a percentage of net revenues, increased to 45.0% from 44.0% as a percentage of net revenues. The primary component of the increase in gross margin dollars and percentage was the increase in net revenues and lower brick production costs.

Selling, general and administrative expenses as a percentage of net revenues, decreased to 21.9% from 24.6% for the same period in 2009 due to the increase in net revenues and decrease in expenses.
