COOPER STANDARD REPORTS SECOND QUARTER 2012 FINANCIAL RESULTS

NOVI, Mich., Aug. 9, 2012—Cooper-Standard Holdings Inc. (OTCBB: COSH), the parent company of Cooper Standard Automotive, a leading global supplier of automotive sealing, fluid and anti-vibration systems, today announced financial results for the second quarter ended June 30, 2012. The Company also reaffirmed its previous outlook for 2012.

“Cooper Standard again achieved double-digit EBITDA margins in the second quarter, despite a fragile and challenging European business environment and softness in other regions,” said Jim McElya, chairman and chief executive officer, Cooper Standard. “Our innovative product offering, global footprint and strategic investments will drive Cooper Standard’s future growth.”

Second quarter and six months ended June 30, 2012 results

The Company reported revenue of $734.5 million for the second quarter of 2012, compared to $760.5 million in the second quarter of 2011. Sales were up 4.3 percent in the quarter when adjusted for $59 million of unfavorable foreign currency movements. Improved sales in North America along with contributions from acquisitions more than offset weakness in Europe.

Revenue for the six months ended June 30, 2012 was $1.50 billion, compared to $1.45 billion in the same period in 2011, reflecting strong vehicle demand in North America and sales from acquired businesses, offsetting varying volume and mix in other regions, and unfavorable foreign currency movement.

Gross profit for the quarter was $114.4 million or 15.6 percent of sales, compared to $123.7 million or 16.3 percent of sales in the second quarter of 2011. Gross profit was impacted by lower European volumes, unfavorable foreign currency movement, increased raw material prices, higher operating costs associated with vehicle launches, production transfers and expansion activities. These negative factors were partially offset by increased vehicle production volume, primarily in North America, and lean initiatives.

The aforementioned factors also contributed to a reduction of gross profit for the six-month period, moving to $236.1 million from $244.5 million in last year’s comparable period.

The Company reported net income of $77.3 million or $3.28 per share on a fully diluted basis in the second quarter of 2012, compared to $19.0 million or $0.71 per share in 2011. Current quarter net income reflected a $53.4 million benefit related to the reversal of the valuation allowance on the Company’s deferred income tax assets in the United States and lower restructuring

expenses, which were partially offset by higher selling, general and administrative expense, unfavorable foreign currency movement and the gross profit items mentioned above. Net income for the six months ended June 30, 2012 was $101.1 million, compared to $64.0 million in the same prior year period. This is primarily reflective of the aforementioned items on a year-to-date basis.

Adjusted EBITDA for the second quarter was $74.1 million, as compared to $90.3 million in 2011. For the six-month period, adjusted EBITDA was $157.3 million, compared to $182.2 million in the prior year period.

2012 guidance

The Company reaffirms its outlook for 2012. Assuming slightly higher North American vehicle production volume of 14.9 million units and European production volume of 18.9 million units, the Company expects:

Net income to adjusted EBITDA reconciliation

The following table provides a reconciliation of EBITDA and adjusted EBITDA to net income, which is the most directly 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.
