Vicor Corporation Announces Third Qtr Results

    ANDOVER, Mass.--(BUSINESS WIRE)--Oct. 19, 2004--Vicor Corporation
(NASDAQ: VICR) today announced its financial results for the quarter
ended September 30, 2004. Revenues for the quarter increased to
$43,048,000 compared with $35,877,000 for the corresponding period a
year ago. The Company reported a net loss for the quarter of $572,000
compared with a net loss of $7,120,000 in the corresponding period of
2003, and a diluted loss per share of $.01 compared with a diluted
loss per share of $.17 in the corresponding period of 2003.
    For the nine months ended September 30, 2004 revenues increased to
$130,943,000 from $112,310,000 for the same period of 2003. The
Company reported a net loss for the period of $1,701,000 compared with
a net loss of $19,707,000 in 2003, and a diluted loss per share of
$.04 compared with a diluted loss per share of $.47 in 2003.
    In the third quarter, revenues increased by 20.0% from the third
quarter of 2003, but decreased by 5.1% on a sequential basis from the
second quarter of 2004. The book to bill ratio for the third quarter
was .94:1 as compared with 1.05:1 in the third quarter of 2003 and
..97:1 in the second quarter of 2004. The Company ended the third
quarter with approximately $38.7 million in backlog compared to $41.2
million at the end of the second quarter and $37.0 million at the end
of 2003.
    In the third quarter, gross margin improved to 37.7%, compared
with 23.9% in the third quarter of 2003.
    Depreciation and amortization in the quarter was $5.2 million and
capital additions were $1.0 million. Depreciation expense decreased
approximately $300,000 from the third quarter of 2003 and decreased
approximately $96,000 from the second quarter of 2004. For the nine
months ended September 30, 2004 depreciation and amortization was
$15.9 million and capital additions were $3.3 million. This compares
with depreciation and amortization of $16.8 million and capital
additions of $4.6 million in the corresponding period of 2003.
    The Company reported a loss before taxes of $72,000 for the
quarter compared with a loss before taxes of $7,803,000 in the
corresponding period of 2003. Tax provisions in 2004 are required as
the Company operates in various state and international taxing
jurisdictions, subject to a variety of income and related taxes, and
due to federal and state taxes for certain minority-owned subsidiaries
that are not part of the Company's consolidated income tax returns.
During the third quarter of 2004, the Company provided additional tax
expense for potential tax liabilities for certain jurisdictions with
open tax periods.
    Inventories increased by approximately $3.9 million to $26.0
million as compared with $22.1 million at the end of 2003 and
increased by approximately $2.2 million from the end of the second
quarter of 2004. The increase in inventories was primarily due to raw
materials and reduced levels of production. The slow down in demand
from major markets and geographies that manifested itself at the end
of the second quarter gained momentum in the third quarter with
customers in affected market segments delaying purchases in the face
of adverse or uncertain market conditions.
    Cash and short-term investments were $114.4 million, a decrease of
approximately $3.0 million from the end of the second quarter of 2004
and an increase of approximately $5.7 million from the end of 2003.
During the quarter, the Company declared and paid a dividend of
approximately $3.4 million, made an additional $1.0 million investment
in a related entity and repurchased 56,900 shares of its Common Stock
for a total of $606,000. The Company has approximately $25.4 million
remaining on its authorized stock buy-back plan.
    During the quarter the Company sampled additional V.I Chips,
including PRM and VTM models. These Factorized Power Architecture
components are slated for general introduction at Electronica, the
World's foremost trade show for assemblies and components in
electronics, taking place in Munich from November 9th to 12th. At
Electronica the Company will also unveil the first family of
VIC-Bricks, DC-to-DC converters made of a PRM and a VTM in an industry
standard Quarter Brick package. VIC-Bricks offer performance and cost
advantages relative to traditional brick assemblies while
demonstrating the power of V.I Chips in the familiar context of an old
standard package. The Company is continuing to develop additional V.I
Chips and increase the breadth of its product offering.
