ANAHEIM – DDi Corp. reported net sales for the fourth quarter of $64.5 million, down 1.8% year-over-year, and down 2.5% sequentially.

Net income was $6.7 million, up 52.3% year-over-year, and up 28.8% sequentially.

Adjusted EBITDA for the fourth quarter of 2011 was $9.6 million, or 14.9% of net sales, compared to $8.7 million, or 13.1% of net sales, in the third quarter of 2011 and $8.4 million, or 12.8% of net sales, in the fourth quarter of 2010.

“In the fourth quarter, we increased our EBITDA more than 10% sequentially and year-over-year, and grew our cash to $31.2 million. As we expected, our fourth quarter’s net sales and bookings were softer than that of prior quarters, reflecting market conditions and the holiday season’s impact,” said Mikel Williams, president and CEO.

As of Dec. 31, DDi sequentially increased its cash and cash equivalents by $2.7 million to $31.2 million.

On Feb. 13, the company completed the purchase of an existing approximately 96,000 sq. ft. building in Anaheim, CA, for $7.5 million, into which it plans to relocate its corporate headquarters and Anaheim manufacturing operations during 2012.
