Dorman Products, Inc. Reports Record Sales and Earnings for the First Quarter Ended March 31, 2012

Colmar, Pennsylvania (May 1, 2012) – Dorman Products, Inc. (NASDAQ:DORM) today announced financial results for the first quarter ended March 31, 2012.

Revenues for the first quarter ended March 31, 2012 increased 10% over the prior year to $137.0 million from $124.4 million. Reported net income in the first quarter increased 26% to $15.6 million from $12.4 million. Reported diluted earnings per share increased 25% to $0.85 in 2012 from $0.68 in the prior year.

Excluding the favorable impact of $0.9 million in reductions to certain reserves associated with the exit of our Swedish business as shown in the reconciliation of non-GAAP measures below, adjusted net income increased 19% to $14.7 million in 2012 from $12.4 million last year. Adjusted diluted earnings per share increased 19% to $0.81 in 2012 from $0.68 in 2011. The exit is expected to be completed in the second quarter.

For the thirteen weeks ended March 31, 2012 and March 26, 2011:

• Gross profit margin was 37.5% in 2012 compared to 36.5% in 2011. Adjusted gross profit margin excluding 0.6%, or $0.8 million, in favorable reductions of certain inventory reserves associated with the exit of our Swedish business was 36.9%. The increase in the gross profit margin in 2012 is primarily related to lower provisions for excess and obsolete inventory.

• Selling, general and administrative expenses increased 3% to $26.9 million from $26.2 million, but declined to 19.6% of sales from 21.1% last year.

• Operating cash flow for 2012 increased to $14.0 million from $9.2 million in 2011.

Mr. Steven Berman, Chairman and Chief Executive Officer, said, “We continue to be pleased with our reported results. Strong demand for our hard parts product lines along with revenues from

new products resulted in a double-digit sales increase over the first quarter of 2011. We are pleased with this result in light of the fact that our revenue for the first quarter of 2011 was 26% greater than our revenue for the first quarter of 2010. A strong focus on expense control despite continued investment in our new product development capabilities enabled us to further leverage our sales growth as well in the first quarter.”
