BAY SHORE, N.Y., Dec. 7, 2010 (GLOBE NEWSWIRE) -- Del Global Technologies Corp. (OTCBB:DGTC) ("Del Global" or "the Company") today announced financial results for its fiscal 2011 first quarter.  

FINANCIAL RESULTS

Consolidated net sales for the fiscal 2011 first quarter increased 34.3% to $15.6 million from $11.6 million in the first quarter of fiscal 2010, due primarily to increased volume at the Medical Systems Group, where net sales increased 40.2% to $13.3 million from $9.5 million in the prior year's first quarter, as a result of increased international customer orders. The Medical Systems Group consists solely of the Villa Sistemi Medicali S.p.A. ("Villa") subsidiary. Sales at the Power Conversion Group, which encompasses the operations of  the Company's RFI Corporation subsidiary ("RFI"), for the first quarter of fiscal 2011 were $2.2 million,  compared to $2.1 million, or 7.7% higher than the prior year's first quarter.

Consolidated gross margin for the fiscal 2011 first quarter was 22.5% as compared to 22.2% in the same period last year.  The Medical Systems Group's first quarter 2011 gross margin of 22.2% was higher than the gross margin of 20.3% in the first quarter of fiscal 2010 due primarily to higher sales volume. The Power Conversion Group's gross margin for the first quarter of fiscal 2011 was 24.1%, versus 31.1% in the prior year first quarter due to higher employee costs, primarily medical insurance expense.

Total operating expenses in the fiscal 2011 first quarter were $2.7 million, or 17.4% of total sales, compared to $2.7 million, or 23.1% of total sales, in the prior year's first quarter.  

Operating income for the fiscal 2011 first quarter was $0.8 million, as compared to an operating loss of $0.1 million in the first quarter of fiscal 2010. The Medical Systems Group generated operating income of $1.3 million in the fiscal 2011 first quarter compared to operating income of $0.2 million for the first quarter of fiscal 2010. The Power Conversion Group posted an operating loss of $0.2 million in the fiscal 2011 first quarter as compared to operating income of $0.1 million in the comparable period last year. Unallocated corporate expenses for the first quarter of fiscal 2011 totaled $0.3 million, as compared to $0.4 million in the prior year.

The discontinued operations had no profit or loss during the first quarter of fiscal 2011. The discontinued operations loss of $3.1 million in the first quarter of fiscal 2010 reflects a $1.3 million loss from operations on sales of $3.5 million and $1.8 million from the write-down of assets to net realizable value.

Net income in the first quarter of fiscal 2011, from continuing operations, was $0.3 million, or $0.01 per basic and diluted share, compared to a net loss of $0.4 million, or $0.02 per diluted share in the prior year period.

In addition, we anticipate closing the $15 million rights offering before the end of the calendar year. This will provide the capital to allow us to consider strategic acquisition alternatives to complement the Company's organic growth plans. We are pleased with the progress of our business unit strategy deployment initiatives, our new product development projects and our lean implementation efforts. We remain concerned about the strength of the worldwide economic recovery and the potential impact U.S. Dept. of Defense efforts to reduce spending may have on our business."
