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,
         they 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 only
         normal recurring adjustments) considered necessary for a fair
         presentation have been included. Operating results for the three- and
         nine-month periods ended September 30, 2001 are not necessarily
         indicative of the results that may be expected for the year ended
         December 31, 2001. For further information, refer to the consolidated
         financial statements and notes thereto included in the Company's
         audited financial statements for the year ended December 31, 2000,
         contained in the Company's annual report filed on Form 10-K (File No.
         0-18277) with the Securities and Exchange Commission.

4. COMPREHENSIVE INCOME

         Total comprehensive income was $417,000 and $1,372,000 for the three
         and nine months ended September 30, 2001, respectively, and $9,931,000
         and $25,010,000 for the three and nine months ended September 30, 2000,
         respectively. Other comprehensive income consisted principally of
         adjustments for foreign currency translation gains (losses) in the
         amounts of $231,000 and ($5,000) and unrealized gains on available for
         sale securities in the amounts of $64,000 and $129,000 for the three
         and nine months ended September 30, 2001, respectively.


5. IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

         In July 2001, the Financial Accounting Standards Board issued Statement
         of Financial Accounting Standards No. 141, (FAS 141), "Business
         Combinations" and No. 142, (FAS 142) "Goodwill and Other Intangible
         Assets." FAS 141 eliminates the pooling-of-interests methods of
         accounting for business combinations, except for qualifying business
         combinations, and further clarifies the criteria to recognize
         intangible assets separately from goodwill. FAS 142 eliminates the
         amortization of goodwill and indefinite lived intangible assets and
         requires periodic review for impairment. The Company is currently in
         the process of evaluating the impact FAS 142 will have on its financial
         position and results of operations.

         In October 2001, the Financial Accounting Standards Board issued
         Statement of Financial Accounting Standards No. 144, (FAS 144),
         "Accounting for the Impairment or Disposal of Long-Lived Assets." FAS
         144 supersedes FAS 121, "Accounting for the Impairment of Long-Lived
         Assets and for Long-Lived Assets to Be Disposed Of" and provides a
         single accounting model for long-lived assets to be disposed of. The
         Company is required to adopt FAS 144 for the fiscal year beginning
         after December 15, 2001 and is currently in the process of evaluating
         the impact on its consolidated financial statements.

RESULTS OF OPERATIONS

THREE MONTHS ENDED SEPTEMBER 30, 2001 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 2000

Net revenues for the third quarter of 2001 were $51,599,000, a decrease of
$16,252,000 (24.0%) as compared to $67,851,000 for the same period a year ago.
The decrease in net revenues resulted primarily from a decrease in unit
shipments of standard and custom products of approximately $14,573,000 and a
decrease in license revenue of $1,679,000. The Company experienced a continued
reduction in demand for its first-generation products which began in the fourth
quarter of 2000. In addition, the Company experienced a reduction in demand for
its second-generation products in the third quarter of 2001. The decrease in
licensing revenue was principally due to the recognition of the final amounts
under the license agreement with Reltec Corporation during the first quarter of
2001.

Gross margin decreased $14,045,000 (46.8%) to $15,985,000 from $30,030,000, and
decreased as a percentage of net revenues from 44.3% to 31.0%. The primary
components of the decreases in gross margin dollars and the corresponding
decrease in percentage were the decrease in net revenues and changes in the
revenue mix resulting from the reduced demand for first-generation products. The
Company continues to refine the design, processes, equipment and parts
associated with second-generation products and is taking steps to increase the
capacity and lower the costs of second-generation manufacturing. Until the
Company achieves higher production volumes, higher yield levels and component
cost reductions on second-generation products, gross margins will continue to be
adversely affected.



                                                                   FORM 10-Q
                                                                   PART I
                                                                   ITEM 2
                                                                   PAGE 7

                                   (continued)



Selling, general and administrative expenses were $11,111,000 for the period, a
decrease of $44,000 (0.4%) over the same period in 2000. As a percentage of net
revenues, selling, general and administrative expenses increased to 21.5% from
16.4%. The principal components of the $44,000 decrease were $376,000 (20.5%) in
decreased sales commission costs and $270,000 (94.8%) in decreased payroll tax
expense associated with the exercise of stock options. The principal components
offsetting the above decreases were $494,000 (108.3%) of increased legal expense
and $144,000 (3.9%) of increased compensation expense.

Research and development expenses decreased $221,000 (4.5%) to $4,741,000 and
increased as a percentage of net revenues to 9.2% from 7.3%. The principal
component of the $221,000 decrease was $308,000 (100.0%) of decreased research
and development expense associated with the operations of Vicor Japan Co., Ltd.
("VJCL") due to a realignment of their activities to applications engineering
beginning in the second quarter of 2001, which is included in selling, general
and administrative expenses. This was offset by $70,000 (14.0%) of increased
project materials costs.

Other income decreased $701,000 (94.3%) from the same period a year ago to
$42,000. Other income is primarily comprised of interest income derived from
invested cash and cash equivalents and short-term investments, as well as a note
receivable associated with the Company's real estate transaction. Other income
for the period included the write-down of an investment of $600,000, for a
decline judged to be other than temporary, and obsolete equipment of $360,000.
The decrease in other income from the same period in 2000 was due to the
write-down of the investment and lower interest income due to a decrease in
average interest rates.

Income before income taxes was $175,000, a decrease of $14,481,000 (98.8%)
compared to income before taxes of $14,656,000 for the same period in 2000. As a
percentage of net revenues, income before income taxes decreased to 0.3% from
21.6% primarily due to the gross margin decrease as discussed above.

The effective tax rate for the third quarter of 2001 was 30.3%, compared to
31.5% for the same period in 2000 due to the lower forecasted income for the
full year 2001 and the effect of expected tax credits and other tax attributes.

Net income per share (diluted) was $.00 for the third quarter of 2001, compared
to $.23 for the third quarter of 2000, a decrease of $.23.

NINE MONTHS ENDED SEPTEMBER 30, 2001 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
2000

Net revenues for the first nine months of 2001 were $156,878,000, a decrease of
$31,537,000 (16.7%) as compared to $188,415,000 for the same period a year ago.
The decrease in net revenues resulted primarily from a decrease of unit
shipments of standard and custom products of approximately $26,749,000 and a
decrease in license revenue of $4,788,000. The decrease in licensing revenue was
primarily due to recognition of the final amounts under the license agreement
with Reltec Corporation during the first quarter of 2001.

                                   (continued)



Gross margin decreased $33,938,000 (41.4%) to $48,015,000 from $81,953,000 and
decreased as a percentage of net revenues from 43.5% to 30.6%. The primary
components of the decreases in gross margin dollars and percentage were due to
the decrease in net revenues, changes in the revenue mix resulting from the
reduced demand for first-generation products and additional provisions for
inventory reserves for potential excess raw materials.

Selling, general and administrative expenses were $32,767,000 for the period, an
increase of $732,000 (2.3%) over the same period in 2000. As a percentage of net
revenues, selling, general and administrative expenses increased to 20.9% from
17.0%. The principal components of the $732,000 increase were $1,102,000 (70.0%)
of increased legal expense and $1,041,000 (9.9%) of increased compensation
expense, offset by a $805,000 (16.3%) decrease in sales commission costs and
$494,000 (79.8%) in decreased payroll tax expense associated with the exercise
of stock options. The increase in legal expense in 2001 was in connection with
activity related to the Company's patent infringement actions (see Part II -
Other Information, Item 1 - Legal Proceedings).

Research and development expenses decreased $55,000 (0.4%) to $15,526,000 and
increased as a percentage of net revenues to 9.9% from 8.3%. The principal
component of the $55,000 decrease was $711,000 (76.6%) of decreased research and
development expense associated with the operations of VJCL due to a realignment
of their activities to applications engineering beginning in the second quarter
of 2001, which is included in selling, general and administrative expenses. This
was offset by $388,000 (4.5%) of increased compensation expense and $190,000
(292.3%) of increased personnel related expenses, principally for employment
recruiting, advertising and relocation expenses.

Other income decreased $636,000 (23.6%) from the same period a year ago to
$2,062,000. Other income is primarily comprised of interest income derived from
invested cash and cash equivalents and short-term investments as well as a note
receivable associated with the Company's real estate transaction. Other income
decreased principally due to lower interest income due to a decrease in average
interest rates.

Income before income taxes was $1,784,000, a decrease of $35,251,000 (95.2%)
compared to the same period in 2000. As a percentage of net revenues, income
before income taxes decreased from 19.7% to 1.1% primarily due to the gross
margin decrease as discussed above.

The effective tax rate for the nine months ended September 30, 2001 was 30.0%,
compared to 31.5% for the same period in 2000. The decrease in the effective tax
rate was due to the impact of expected tax credits in 2001.

Net income per share (diluted) was $.03 for the nine months ended September 30,
2001, compared to $.59 for the same period in 2000, a decrease of $.56.

LIQUIDITY AND CAPITAL RESOURCES

At September 30, 2001 the Company had $63,909,000 in cash and cash equivalents.
The ratio of current assets to current liabilities was 9.2:1 at September 30,
2001 compared to 7.3:1 at December 31, 2000. Working capital increased
$7,577,000, from $146,478,000 at December 31, 2000 to $154,055,000 at September
30, 2001. The primary factors affecting the working capital increase were an
increase in cash, cash equivalents and short-term investments of $9,322,000, the
reclassification of a note receivable of $7,500,000 to a current asset as it is
now due within one year and the decrease in current liabilities of $4,398,000,
offset by a decrease in accounts receivable of $15,663,000. The primary sources
of cash were $26,030,000 from operating activities and $1,371,000 from the
issuance of Common Stock upon the exercise of stock options. The primary uses of
cash for the nine months ended September 30, 2001 were for the purchases of
short-term investments of $8,200,000 and additions to property and equipment of
$18,265,000.

The Company's primary liquidity needs are for making continuing investments in
manufacturing equipment, much of which is built internally, particularly for the
Company's second-generation products. The internal construction of manufacturing
machinery, in order to provide for additional manufacturing capacity, is a
practice which the Company expects to continue over the next several years.
While manufacturing capacity for second-generation products has increased over
the past several quarters, the Company continues to take steps to increase the
capacity of second-generation manufacturing, which includes adding equipment and
re-deploying equipment from first-generation production. In February 2001,
management approved approximately $16 million in new capital expenditures to
execute this plan. Through September 30, 2001, the Company has spent
approximately $7,000,000 under this plan and anticipates additional spending of
approximately $2,000,000 through the end of 2001.

In November 2000, the Board of Directors of the Company authorized the
repurchase of up to $30,000,000 of the Company's Common Stock (the "November
2000 Plan). The November 2000 Plan authorizes the Company to make such
repurchases from time to time in the open market or through privately negotiated
transactions. The timing of this program and the amount of the stock that may be
repurchased are at the discretion of management based on its view of economic
and financial market conditions. There were no stock repurchases during the nine
months ended September 30, 2001.

The Company believes that cash generated from operations and the total of its
cash and cash equivalents, together with other sources of liquidity, will be
sufficient to fund planned operations and capital equipment purchases for the
foreseeable future. At September 30, 2001, the Company had approximately
$1,800,000 of capital expenditure commitments.

The Company does not consider the impact of inflation and changing prices on its
business activities or fluctuations in the exchange rates for foreign currency
transactions to have been significant during the last three fiscal years.

COST REDUCTION PLAN

In October 2001, the Company announced a cost reduction plan which included the
following temporary steps: (1) a reduced work schedule for hourly employees, (2)
mandatory use of accrued personal time by salaried employees and (3) a 10% pay
reduction for the Company's officers. The Company expects that additional stock
options will be granted from time to time to the Company's employees in
connection with the Cost Reduction Plan.


ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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. The Company's exposure to
market risk for a change in interest rates relates primarily to the Company's
cash and cash equivalents and short-term investments.

As the Company's cash and cash equivalents consist principally of money market
securities, which are short-term in nature, the Company's exposure to market
risk on interest rate fluctuations is not significant. The Company's exposure to
market risk for fluctuations in foreign currency exchange rates relates
primarily to the operations of VJCL. The Company believes that this market risk
is currently not material due to the relatively small size of VJCL's operations.

                               September 30, 2001


ITEM 1 - LEGAL PROCEEDINGS

         As previously disclosed in the Company's Forms 10-Q for the fiscal
         quarters ended March 31 and June 30, 2001, in June 1998 the Company and
         VLT Corporation (which has since merged with and into VLT, Inc., a
         wholly-owned subsidiary of the Company) filed a lawsuit in the United
         States District Court of Massachusetts alleging that Unitrode
         Corporation ("Unitrode") has infringed and is infringing U.S. Reissue
         Patent No. 36,098 (the "Reset Patent") entitled "Optimal Resetting of
         the Transformer's Core in Single Ended Forward Converters." The Reset
         Patent is a reissue of U.S. Patent No. 4,441,146, which issued on April
         3, 1984. On January 24, 2001, the Court issued a summary judgment
         decision in which the Court concluded that the Reset Patent is not
         anticipated by certain prior art. The Court further concluded that the
         Reset Patent is not invalid for failure to disclose the best mode of
         practicing the invention, nor is it invalid for indefiniteness. The
         Court also concluded that certain single-ended forward converters,
         built by Unitrode and four of its customers using certain Unitrode
         integrated circuits ("chips"), had infringed the Reset Patent. The
         Court declined to rule on certain other matters relating to the Reset
         Patent, and those matters were made the subject of a jury trial, which
         concluded on May 25, 2001 with the jury rendering a verdict in which it
         upheld the validity of the Reset Patent. The jury also found that
         Unitrode had not induced the four customers to infringe the Reset
         Patent. On September 4, 2001, Unitrode filed a notice of appeal in the
         US Court of Appeals for the Federal Circuit seeking to overturn the May
         25, 2001 jury verdict of patent validity. Vicor opposed Unitrode's
         appeal and filed a cross-appeal seeking to overturn the May 25, 2001
         jury verdict of non-inducement. On October 23, 2001 the Company
         announced that it had entered into a settlement with Unitrode, under
         which the parties agreed to withdraw their respective appeals and
         dismiss their respective claims. The Company has retained its right to
         recover damages directly from infringers using Unitrode chips.

         Given the validity verdict, Vicor and VLT, Inc. are pursuing their
         infringement claims directly against Artesyn Technologies, Lambda
         Electronics, Lucent Technologies and Power-One in the United States
         District Court in Boston, Massachusetts. The lawsuit against Lucent was
         filed in May 2000 and the lawsuits against the other defendants were
         filed in February and March 2001. On April 6, 2001, Vicor and VLT moved
         to add Tyco Electronics Power Systems, Inc. as a defendant in the
         Lucent proceeding. Tyco Electronics Power Systems, Inc. is the entity
         which now operates the former power component business of Lucent. Vicor
         and VLT, Inc. are seeking monetary damages and injunctive relief in
         these suits.

         On July 23, 2001, the Company announced that it had entered into a
         license agreement with Siemens Corporation under which Siemens acquired
         worldwide, non-exclusive rights to use power conversion technology
         covered by the Reset Patent. In connection with entering into this
         license agreement, the Company and VLT, Inc. agreed to dismiss their
         patent infringement claims against Siemens which were filed in the
         United States District Court in Boston, Massachusetts in March 2001.

         On October 2, 2001, the Company announced that it had entered into a
         license agreement with Magnetek, Inc. under which Magnetek acquired
         worldwide, non-exclusive rights to use power conversion technology
         covered by the Reset Patent. In connection with entering into this
         license agreement, the Company and VLT, Inc. agreed to dismiss their
         patent infringement claims against Magnetek which were filed in the
         United States District Court in Boston, Massachusetts in February 2001.

         The Company is involved in certain other litigation incidental to the
         conduct of its business. While the outcome of these lawsuits against
         the Company cannot be predicted with certainty, management does not
         expect these lawsuits to have a material adverse impact on the Company.
