Vicor Corporation Reports Results for the Fourth Quarter Ended December 31, 2012

ANDOVER, MA -- (Marketwire - February 26, 2013) - Vicor Corporation (NASDAQ: VICR) today reported financial results for the fourth quarter and year ended December 31, 2012.

Revenues for the fourth fiscal quarter ended December 31, 2012, decreased to $50,424,000, compared to $58,551,000 for the corresponding period a year ago, and decreased from $52,948,000 for the third quarter of 2012.

Gross margin decreased to $20,125,000 for the fourth quarter of 2012, compared to $24,491,000 for the corresponding period a year ago, and decreased from $22,953,000 for the third quarter of 2012. Gross margin, as a percentage of revenue, decreased to 39.9% for the fourth quarter of 2012 compared to 41.8% for the fourth quarter of 2011, and decreased on a sequential basis from 43.4% for the third quarter of 2012.

Net loss for the fourth quarter was ($4,814,000), or ($0.12) per share, compared to net income of $677,000, or $0.02 per diluted share, for the corresponding period a year ago and net income of $191,000, or $0.00 per diluted share, for the third quarter of 2012. Contributing to the net loss in the fourth quarter were non-cash charges for an impairment to goodwill related to the Company's subsidiary in Japan of $2,012,000, an increase in the Company's tax valuation allowance against certain deferred tax assets of $1,489,000, and an increase to inventory reserves of approximately $1,400,000 for potential excess and obsolete inventories, charged against cost of revenues. These charges were partially offset by a gain from litigation-related settlement, as Vicor settled its lawsuit against its insurance carriers, receiving a cash payment of $1,975,000 in October 2012.

Revenues for the year ended December 31, 2012, decreased by 13.6% to $218,507,000 from $252,968,000 for the corresponding period a year ago. Net loss for the year was ($4,077,000), or ($0.10) per share, compared to net income of $8,843,000 or $0.21 per diluted share, for the corresponding period a year ago.

Total backlog at the end of the fourth quarter was $31,405,000, compared to $54,234,000, at the end of 2011 and $42,880,000 at the end of the third quarter of 2012.

Commenting on the fourth quarter, Patrizio Vinciarelli, Chief Executive Officer, stated, "Our fourth quarter results reflect depressed bookings in the second half of 2012. Poor capacity utilization during the quarter caused our actual loss from operations to be larger than forecast, and substantial non-cash charges pushed our net loss to the level reported. Based upon a 27% decline in fourth quarter bookings and an anticipated partial recovery in first quarter bookings, we are expecting first quarter revenue and operating results to be sequentially lower than in the fourth quarter. We do not expect improved consolidated performance until the markets and applications on which we have traditionally focused strengthen and our new products and market initiatives build adequate momentum. We have confidence in these initiatives in part because of the high level of interest already established with key customers and applications and remain focused on executing our plan."

Depreciation and amortization for the fourth quarter of 2012 was approximately $2,553,000, and capital additions totaled $2,558,000. In 2012, depreciation and amortization was $10,423,000 and capital additions totaled $7,396,000, compared to $11,005,000 and $7,466,000, respectively, for 2011. Cash and cash equivalents increased by $12,646,000 to approximately $84,554,000 at the end of 2012 from $71,908,000 at the end of 2011. There were no share repurchases during the quarter, and approximately $8,500,000 remains authorized for additional purchases.

In February 2013, reflecting near term demand expectations, the Company undertook a reduction in force. The Company expects to record a pre-tax charge in the first quarter of 2013 of approximately $1,300,000 for the cost of severance and other employee-related costs, based on each employee's respective length of service.
