WARREN, Ohio – February 7, 2013 – Stoneridge, Inc. (NYSE: SRI) today announced that it expects 2013 sales to be in the range of $939 million to $974 million and earnings per share to be in the range of $0.75 to $0.95 per share. See financial schedule below:

2013 Sales and Earnings Guidance:

“Though the markets we serve remain uncertain, we expect the improved earnings on a minimal sales increase in 2013 to result largely from the cost actions implemented in 2012 and the continuous operating improvements we are driving in all of our operations,” said John C. Corey, President and Chief Executive Officer. “We expect our sales and earnings cadence to be stronger in the latter half of 2013 as our major markets improve. We also expect our first-half earnings performance in 2013 to exceed our first-half earnings performance in 2012, though on a lower sales level. We remain cautiously optimistic about our markets and enthusiastic about our ability to deliver improved earnings performance and strong cash flow. Our long-term growth opportunities remain intact as we have the right strategy, people and investments in place to support our plans for future growth and are positive about 2013 financial and operational results.”

Fourth-Quarter Update:

“We finished 2012 with strong cash flow and we have exceeded our debt reduction targets. We finished the year generating approximately $49.3 million in free cash flow (cash flow from operations less capital expenditures) and our debt reduction in 2012 was approximately $65.7 million; $38.0 million from our asset-based lending facility in the U.S. and the remaining $27.7 million primarily from PST debt,” Corey said.

“We continued to see improvement in the fourth quarter compared with the second and third quarters. We currently estimate fourth-quarter sales to approximate $224.0 million and earnings per share to be in the range of $0.10 to $0.14 per diluted share, which are below our expectations and our previously published guidance, due primarily to a slower recovery in the Brazilian market than anticipated,” Corey noted. “The Company’s margins were also affected by lower-than-expected sales in its core businesses (Electronics and Control Devices segments), primarily in its European operations, as European OEMs extended their holiday shutdown longer than we expected, but both gross margin and operating margin continued to improve in the fourth quarter compared with the second and third quarters.”

Corey added, “We continued to see improvement in PST’s sales and earnings in the fourth quarter. Sales increased by about 6% over the third quarter but were affected by continued weakness in GDP growth in Brazil, which was in the 1.0% to 1.2% range. However, due to the lower-than-expected sales and the corresponding drop in operating income at PST, most of the variance from our consolidated guidance was attributed to our PST operation. We believe that with the cost initiatives that have been implemented and an improving Brazilian market, PST will improve at the operating income line with 2013 sales being equal to or down compared with 2012. Though PST has experienced significant market headwinds this year, we are pleased with PST’s response to the changing economic conditions and look forward to improved financial performance as the Brazilian economy improves and new product sales in cargo tracking and home security systems are introduced. We will elaborate further on our fourth-quarter results during our conference call scheduled for March 1, 2013.”
