AURORA, CO -- Advanced Circuits saw revenue climb 6% year-over-year in the second quarter, boosted by acquisitions, company executives said.

For the quarter ended June 30, printed circuit board fabricator's revenue increased to $21.2 million, mainly due to the acquisition of Universal Circuits, which was completed in May. Income from operations was $5.9 million, down from $6.8 million in 2011, driven by promotional pricing largely for customers in the firm's Tempe, AZ, facility and for transaction expenses related to the Universal acquisition.

For the first half, revenue was $40.6 million, essentially flat as compared to $40.3 million in the prior year. Income from operations was $12.1 million, down from $13.9 million last year.

Operating margins for the period slipped several hundred basis points below what the firm had experienced for the past several quarters on price discounts in the defense business and the acquisition of Universal Circuits, which operates on lower margins.

The printed circuit board fabricator "continues to see steady demand for its core quickturn business, but lower revenues and margin pressures in the defense business. We expect these conditions to remain in place for the remainder of 2012," said Elias Sabo, partner at Compass Group Management, the holding company that owns Advanced Circuits.

Advanced Circuits acquired Maple Plain, MN-based Universal Circuits in May for $2.3 million.
