NOVI, Mich., Feb. 25, 2013 - Cooper-Standard Holdings Inc. (OTCBB: COSH), the parent company of Cooper Standard Automotive, a leading global supplier of systems and components for the automotive industry, today announced financial results for the fourth quarter and year ended December 31, 2012. The Company also provided its 2013 outlook.

“The company’s global investments in 2012 highlight our strategic focus on growth, emerging market expansion and support of our global customers,” said Jeffrey Edwards, CEO, Cooper Standard. “We will continue to work closely with our customers to identify profitable growth opportunities in 2013.”

Fourth quarter and 2012 results

Cooper Standard reported revenue of $697.1 million for the fourth quarter of 2012 as compared to $695.7 million in the same quarter of the previous year. Sales reflect increased OEM production volume in North America, offset by volume declines in Europe and $10.8 million of unfavorable foreign exchange. For the full year, revenue was $2.9 billion, up slightly from the previous year. On a comparable basis, revenue was up 5.5 percent when adjusted for $129.4 million of unfavorable foreign exchange during the year. In addition to the aforementioned factors, the businesses acquired by the Company in 2011 also contributed favorably to 2012.

Gross profit for the quarter ended December 31, 2012 was $99.7 million or 14.3 percent of sales as compared to $97.6 million or 14 percent of sales for the fourth quarter of 2011. Lean savings contributed to the increase in gross profit, offset primarily by customer pricing and vehicle launch and expansion expense.

For the full year 2012, the Company generated a gross profit of $438.9 million, representing 15.2 percent of sales, compared to $450.6 million in 2011, or 15.8 percent of sales. Factors affecting gross profit in the year include increased production volume in North America and lean savings, offset by lower European volumes, unfavorable foreign exchange, customer pricing and expenses associated with vehicle launches, manufacturing transfers and expansion activities.

The Company reported net loss of $9.9 million in the fourth quarter of 2012, compared to net income of $23.2 million in 2011. Net income for the quarter was affected by after tax charges of $12.5 million in connection with the Company’s European restructuring initiatives and $9.1 million of impairment charges relating to the Company’s South American business and one of its European facilities. Selling, administration and engineering expenses increased to $74.8 million in the fourth quarter of 2012, compared to $66.7 million in 2011, as the Company increased staffing and investments to support its customers and growth initiatives.

Net income to adjusted EBITDA reconciliation

The following table provides a reconciliation of EBITDA and adjusted EBITDA to net income, which is the most comparable U.S. GAAP financial measure (dollars in millions):

Management considers EBITDA and adjusted EBITDA as key indicators of the Company’s operating performance and believes that these and similar measures are widely used by investors, securities analysts and other interested parties in evaluating the Company’s performance. Adjusted EBITDA is defined as net income adjusted to reflect income tax expense, interest expense net of interest income, depreciation and amortization, and certain non-recurring items that management does not consider to be reflective of the Company’s core operating performance.

When analyzing the Company’s operating performance, investors should use EBITDA and adjusted EBITDA in addition to, and not as alternatives for, net income, operating income, or any other performance measure derived in accordance with GAAP, or as an alternative to cash flow from operating activities as a measure of the Company’s performance. EBITDA and adjusted EBITDA have limitations as analytical tools and should not be considered in isolation or as substitutes for analysis

of the Company’s results of operations as reported under GAAP. Other companies may report EBITDA and adjusted EBITDA differently and therefore Cooper Standard’s results may not be comparable to other similarly titled measures of other companies. In addition, in evaluating adjusted EBITDA, it should be noted that in the future Cooper Standard may incur expenses similar to or in excess of the adjustments in the above presentation. This presentation of adjusted EBITDA should not be construed as an inference that Cooper Standard’s future results will be unaffected by unusual or non-recurring items.
