FOR IMMEDIATE RELEASE

STONERIDGE REPORTS STRONG FIRST-QUARTER 2012 RESULTS

AS NET SALES INCREASE MORE THAN 35 PERCENT

- Improved operating performance drives EPS growth -

- Company maintains full-year sales and EPS guidance -

WARREN, Ohio – May 1, 2012 – Stoneridge, Inc. (NYSE: SRI) today announced strong financial results for the first quarter ended March 31, 2012.

Net sales in the first quarter of 2012 increased $69.2 million, or 35.9%, to $262.3 million, compared with $193.0 million for the first quarter of 2011. The increase in net sales reflects the consolidation of the operating results of PST, the Brazilian joint venture in which the Company now has a controlling ownership interest. Excluding the results of PST in the first quarter of 2012, net sales were $208.6 million, an increase of $15.6 million, or approximately 8%, from a year ago as a result of increased production volumes in most of the Company’s served markets.

Net income for the first quarter of 2012 was $5.9 million, or $0.22 per diluted share, compared with a net income of $2.9 million, or $0.12 per diluted share, in the first quarter of 2011. The increase in net income was primarily due to improved operational profitability in the wiring business, as well as more favorable copper costs and Mexican peso exchange rate compared with the first quarter of 2011.

As of March 31, 2012, Stoneridge’s consolidated cash position was $42.9 million, which was $35.8 million lower than its 2011 year-end balance of $78.7 million. The change in the cash balance was primarily the result of the $19.8 million in cash used to fund the final portion of the PST transaction, which was completed on January 5, 2012, and higher accounts receivable from increased sales.

Outlook

“I am pleased with our performance and execution in the first quarter,” said John C. Corey, president and chief executive officer. “The hard work by our team to enhance our wiring business margins is clearly paying off as evidenced by the return of our gross margin to more normal levels in the first quarter. As expected, we have also benefited from the moderating costs for copper and the Mexican peso.

“As we look ahead at the balance of 2012, we now see some near-term softness, especially in the Brazilian and European markets, that may impact our quarterly performance,” said Corey. “However, we still anticipate achieving our previous full-year sales guidance in the range of $1.060 billion to $1.120 billion. We remain confident in our ability to continue to improve operations and execute against our growth strategy while managing our cost structures. As a result, we are maintaining our full-year earnings guidance of $1.10 to $1.30 per diluted share.”
