EARNINGS RELEASE DELAYED

— Earnings are expected to meet previously announced guidance excluding non-cash items —

WARREN, Ohio – January 25, 2005 – Stoneridge, Inc. (NYSE: SRI) announced today that its fourth-quarter 2004 net income is expected to be within the Company’s previously announced range of $0.12 to $0.22 per diluted share, excluding the impact of certain non-cash items including the pre-tax charge of $175.0 to $195.0 million for the impairment of goodwill, which was previously announced on January 5, 2005. Including the goodwill impairment charge, the Company will report a loss for the fourth quarter and full year 2004. Fourth-quarter sales were approximately $163 million compared with $151.2 million for the fourth quarter of 2003.

The Company has rescheduled its fourth-quarter earnings conference call to February 8, 2005 at 11 a.m. EST. The Company will issue a separate release in the near future with call-in information for the conference call. The delay results from the Company’s need for additional time to finalize the goodwill impairment charge and related matters.
