Exhibit No. Description
99.1 Press Release of Vicor Corporation dated April 22, 2010

Vicor Corporation Reported Its Financial Results for the First Quarter Ended March 31, 2010

ANDOVER, MA -- (Marketwire - April 22, 2010) - Vicor Corporation (NASDAQ: VICR) (the "Company") today reported its financial results for the first quarter ended March 31, 2010.

Revenues for the first fiscal quarter ended March 31, 2010, increased to $51,709,000, compared to $50,448,000 for the corresponding period a year ago, and increased from $49,138,000 for the fourth quarter of 2009. Gross margin increased to $23,324,000 for the first quarter of 2010, compared to $21,831,000 for the corresponding period a year ago and $22,497,000 for the fourth quarter of 2009. Gross margin, as a percentage of revenue, increased to 45.1% for the first quarter of 2010 compared to 43.3% for the first quarter of 2009, but decreased on a sequential basis from 45.8% for the fourth quarter of 2009. Net income for the first quarter was $1,952,000, or $0.05 per diluted share, compared to a net loss of $(2,543,000), or $(0.06) per diluted share, for the corresponding period a year ago and net income of $2,309,000, or $0.06 per diluted share, for the fourth quarter of 2009. Results for the first quarter of 2009 were negatively impacted by a pre-tax charge of $3,098,000 for severance and other employee-re lated costs in connection with a workforce reduction implemented during the quarter.

Commenting on the Company's performance, Patrizio Vinciarelli, Chairman of the Board, President and Chief Executive Officer, stated, "Each of our three primary business units experienced improved bookings and revenue. Consolidated revenue increased 5.2% sequentially, while the consolidated book-to-bill ratio for the first quarter was 1.39:1, as compared to 1.16:1 for the fourth quarter of 2009. Total backlog at the end of the first quarter of 2010 was $78,407,000, as compared to $58,489,000 at the end of 2009."

"Our brick components business grew sequentially, with particular strength in its configurable product lines. V-I Chip revenue for the first quarter grew 99% sequentially, while bookings grew at a faster pace as a large customer placed initial production orders for new programs. V-I Chip also received initial orders from other early adopters of Factorized Power. With increased volume, we expect to achieve improvement in product-level profitability, although we do not expect to reach our efficiency and margin targets in 2010. "

Dr. Vinciarelli concluded, "Picor also grew sequentially and experienced strong bookings. Picor is collaborating closely with V-I Chip in providing distinctive power management solutions and, in particular, is sharing in V-I Chip's success with important early adopters."

Depreciation and amortization for the first quarter of 2010 was approximately $2,432,000, and capital additions totaled $2,429,000. For the same period of 2009, depreciation and amortization was $2,625,000 and capital additions totaled $1,029,000. Cash, restricted cash equivalents and short-term investments decreased by $574,000 to approximately $42,425,000 at the end of the first quarter of 2010 from $42,999,000 at the end of 2009. There were no share repurchases during the quarter, and approximately $8,500,000 remains authorized for additional purchases under the Company's stock repurchase plan.

As of March 31, 2010, the Company held approximately $30,075,000, at par value, of auction rate securities classified as long-term investments. As previously disclosed, conditions in the market for auction rate securities and the repeated failure of auctions by which such securities are priced have led the Company to classify its holdings as long-term investments and reduce their carrying value to an estimated market value. 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 of holdings of auction rate securities will affect the Company's ability to execute its current operating plan.

The tax provisions in 2010 and 2009 provide for estimated income taxes due in various state and international taxing jurisdictions, estimated alternative minimum tax, 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, offset by the expected utilization of federal and foreign net operating loss carryforwards. The 2010 and 2009 tax provisions also include discrete items, principally expense for increases in state taxes and accrued interest for potential liabilities.
