DDi Corp. Announces Second Quarter 2010 Results

ANAHEIM, Calif., July 29, 2010 – DDi Corp. (NASDAQ: DDIC), a leading provider of time-critical, technologically advanced electronic interconnect design, engineering and manufacturing services, today reported financial results for the second quarter ended June 30, 2010.

Second Quarter 2010 Highlights:

Mikel Williams, President and Chief Executive Officer of DDi Corp., stated, “We are extremely pleased to achieve another quarter of strong operating and financial performance. Through the ongoing execution of our business strategy, we have continued to build upon our financial position having delivered four consecutive quarters of increasing sales, expanding margins and controlled operating expenses. Our solid performance has been driven by robust customer demand for our products and services coupled with strong operational execution of our business plan. Highlighting our continued focus on developing leading electronic interconnect solutions, during the second quarter we continued to introduce cutting-edge capabilities that underpin DDi’s position in the market place. As an example, we passed the $1 million mark in customer orders in 2010 for our new and disruptive NextGen-SMV^® technology, and we look forward to further extending this enabling technology to our customers going forward.”

Mr. Williams continued, “Importantly, with second quarter bookings of approximately $69.7 million and indications of continued solid demand in the marketplace, we are optimistic about our prospects for the second half of 2010. Based upon our performance to-date, we are increasing

our 2010 estimate for net sales growth, and now expect net sales growth of 20% to 25% over 2009 pro-forma net sales of $220 million.”

Second Quarter Results

Net sales for the second quarter of 2010 were $68.4 million, an 84% increase over the prior year quarter and a 5.7% increase sequentially. The sequential increase reflects continued strength in the end-market, particularly within the Company’s commercial segment, as well as continued progress in targeted vertical markets such as the military/aerospace sector.

Gross margin for the second quarter of 2010 increased 443 basis points year-over-year to 22.4% of net sales from 18.0% of net sales in the prior year period. Sequentially, gross margin increased 77 basis points from 21.6% of net sales. The sequential and year-over-year improvement in gross margin was primarily driven by improved operational efficiencies derived from the net sales increase and operating expense controls. This was partially offset by a decline in gross margin for the Company’s Toronto based facilities, resulting from the facilities’ ongoing integration and consolidation efforts.

Operating income in the second quarter of 2010 was $6.8 million, or 9.9% of net sales, compared to operating income of $0.8 million, or 2.2% of net sales, in the prior year period. Operating income in the first quarter of 2010 was $4.9 million, or 7.5% of net sales.

Adjusted EBITDA for the second quarter of 2010 was $9.8 million, or 14.3% of net sales, compared to $3.6 million, or 9.6% of net sales, in the prior year period. Adjusted EBITDA for the first quarter of 2010 was $8.4 million, or 13.0% of net sales. Reconciliations of this non-GAAP measure are provided after the GAAP condensed consolidated financial statements below and exclude non-recurring costs associated with the Coretec acquisition, including facility closure, severance and professional fees.

Net income in the second quarter of 2010 was $6.0 million, or $0.29 per share, compared to net income of $0.4 million, or $0.02 per share, in the prior year period. Net income in the first quarter of 2010 was $3.8 million, or $0.19 per share.

Second Quarter Balance Sheet and Liquidity

As of June 30, 2010, DDi had total cash and cash equivalents of $15.5 million and total debt of $12.1 million. Net working capital as of June 30, 2010 was $45.5 million, an increase of $5.0 million from March 31, 2010.

For the three and six months ended June 30, 2010, capital expenditures totaled $2.3 million and $3.6 million, respectively.

On May 13, 2010, the Company announced that its Board of Directors approved the initiation of a cash dividend to its shareholders. The quarterly dividend of $0.06 per share was paid on July 6, 2010, to shareholders of record on the close of business on June 21, 2010.

Non-GAAP Financial Measures

This release includes ‘adjusted EBITDA’, a non-GAAP financial measure as defined in Regulation G of the Securities Exchange Act of 1934. Management believes that the disclosure of non-GAAP financial measures, when presented in conjunction with the corresponding GAAP measures, provide useful information to the Company, investors and other users of the financial statements and other financial information in identifying and understanding operating performance for a given level of net sales and business trends. Management believes that adjusted EBITDA is an important factor of the Company’s business because it reflects financial performance that is unencumbered by debt service and other non-cash, non-recurring or unusual items. This financial measure is commonly used in the Company’s industry. However, adjusted EBITDA should not be considered as an alternative to cash flow from operating activities, as a measure of liquidity or as an alternative to net income as a measure of operating results in accordance with generally accepted accounting principles. The Company’s definition of adjusted EBITDA may differ from definitions of such financial measure used by other companies. The Company has provided a reconciliation of adjusted EBITDA to GAAP financial information in the attached Schedule of Non-GAAP reconciliations.

“Safe Harbor” Statement under the Private Securities Litigation Reform Act of 1995

Except for historical information contained in this release, statements in this release may constitute forward-looking statements regarding the Company’s assumptions, projections, expectations, targets, intentions or beliefs about future events. Words or phrases such as “anticipates,” “believes,” “estimates,” “expects,” “intends,” “plans,” “predicts,” “projects,” “targets,” “will likely result,” “will continue,” “may,” “could” or similar expressions identify forward-looking statements.

The Company cautions that while it makes such statements in good faith and it believes such statements are based on reasonable assumptions, including without limitation, management’s examination of historical operating trends, data contained in records, and other data available from third parties, it cannot assure you that the Company’s projections will be achieved. In addition to other factors and matters discussed from time to time in the Company’s filings with the U.S. Securities and Exchange Commission, or the SEC, some important factors that could cause actual results or outcomes for DDi or its subsidiaries to differ materially from those discussed in forward-looking statements include changes in general economic conditions in the markets in which it may compete and fluctuations in demand in the electronics industry; the Company’s ability to sustain historical margins; increased competition; increased costs; loss or retirement of key members of management; currency exchange rate fluctuations; integration of acquired operations; international operations; compliance with environmental regulations; increases in the Company’s cost of borrowings or unavailability of additional debt or equity capital on terms considered reasonable by management; and adverse state, federal or foreign legislation or regulation or adverse determinations by regulators. Any forward-looking statement speaks only as of the date on which such statement is made, and, except as required by law, the Company undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for management to predict all such factors.
