CORE MOLDING TECHNOLOGIES REPORTS SECOND QUARTER 2010 RESULTS

COLUMBUS, Ohio – August 11, 2010 – Core Molding Technologies, Inc. (NYSE Amex: CMT) today announced results for the second quarter and six months ended June 30, 2010.

The Company recorded net income for the second quarter of 2010 of $441,000, or $.06 per basic and diluted share, compared with a net loss of $845,000, or $.12 per basic and diluted share, in the second quarter of 2009. Total net sales for the second quarter were $23,476,000, compared with $17,300,000 in the same quarter of 2009. Product sales for the three months ended June 30, 2010 increased 29 percent, to $21,473,000, from $16,644,000 for the same period one year ago. The increase in sales is primarily due to a higher demand in the North American medium and heavy-duty truck market. Negatively impacting the second quarter’s results were approximately $1,000,000 of expense for transfer costs associated with the previously announced move of certain product lines from the Company’s Columbus, Ohio production facility to the Company’s Matamoros, Mexico production facility.

For the first six months of 2010, net income was $304,000, or $.04 per basic and diluted share, compared with net loss of $1,482,000, or $.22 per basic and diluted share, for the first six months of 2009. Excluding a one-time non-cash income tax charge of $1,021,000 related to changes in U.S. healthcare legislation in the first quarter of 2010, net income for the first six months of 2010 was $1,325,000 or $.19 per share. Total net sales for the first half of 2010 were $43,918,000, compared with $35,684,000 in the first half of 2009. Product sales for the first six months of 2010 increased 19 percent, to $41,169,000 compared to $34,474,000 for the same period in 2009. Negatively impacting the first six months results were approximately $1,320,000 of expense for transfer costs associated with the move of certain production between the Company’s facilities as noted above.

Barnett, President and Chief Executive Officer. “While the market has not fully recovered, we are seeing some positive signs of improvement,” Barnett continued. “As we continue to look forward to a full market recovery, our efforts will remain focused on identifying new opportunities, on serving our current customers and improving our operations,” Barnett said.
