Gross margin, as a percentage of revenue, increased to 47.2% for the second quarter of 2015, compared to 42.5% for the second quarter of 2014, and increased from 45.1% for the first quarter of 2015.

Net income for the second quarter was $805,000, or $0.02 per diluted share, compared to a net loss of ($4,835,000), or ($0.13) per share, for the corresponding period a year ago and net income of $3,371,000, or $0.09 per diluted share, for the first quarter of 2015.

Revenues for the six months ended June 30, 2015, increased by 12.7% to $120,136,000 from $106,594,000 for the corresponding period a year ago. Net income for the six month period was $4,176,000, or $0.11 per diluted share, compared to a net loss of ($10,213,000), or ($0.26) per share, for the corresponding period a year ago.

Commenting on recent results, Dr. Patrizio Vinciarelli, Chief Executive Officer, stated, "Vicor's second quarter performance reflects the circumstances described during our February and April earnings calls as the pull-in of shipments from Q2 into Q1 of our Gen 3 VTM/PRM solution for data center servers and a delayed transition from the current voltage regulation standard, VR 12.5, to Intel's next generation standard, VR 13.0, have caused a temporary reduction in revenues and bookings. We are prepared to ship our next generation solution meeting VR 13.0 requirements, but await definiteness as to the exact timing of the expected ramp for data center servers due to ship in robust volumes in 2016."

"Despite near-term disappointment in our revenue levels and bottom line, I continue to see escalating interest in Vicor power components and system products. We are achieving design wins in numerous applications across targeted market segments, which I am confident will expand our revenue, while diversifying our customer base. We will be rolling out exciting new products through the second half of the year at a pace similar to that achieved for the first half, with high performance SiP (System in Package), ChiP (Converter housed in Package™) solutions for motherboard applications and VIA (Vicor Integrated Adapter™) front-end systems. I am pleased Vicor was profitable and generated cash for the second quarter, despite short-term challenges. I also am pleased the organization is focused on our long-term objective of redefining the market for high performance, cost effective modular power solutions."
