CORE MOLDING TECHNOLOGIES REVISES ANNUAL SALES FORECAST

COLUMBUS, Ohio – July 25, 2005 – Core Molding Technologies, Inc. (AMEX: CMT) today announced that it is downwardly adjusting its annual sales forecast due to the decision of a customer to move some of its business to alternative manufacturers.

The Company has adjusted its 2005 revenue projection to a range of approximately $120 million to $122 million, down from $125 million. The company reported 2004 revenues of $111.8 million. The revised annualized forecast excludes the 2005 expected revenue of $ 6 million to $7 million from the Company’s previously announced Letter of Intent to acquire certain assets of the Cincinnati Fiberglass Division of Diversified Glass (CFG).

Yamaha, which accounted for $13.7 million of sales in 2004, has recently elected to purchase a portion of its requirements from other suppliers. Core anticipates sales to Yamaha at approximately $6 million to $7 million on an annual basis going forward.

“We believe our near term outlook continues to appear favorable,” said James L. Simonton, president and chief executive officer. “While we are disappointed whenever a customer chooses an alternative supplier, Yamaha remains an important and valued customer. We still expect that 2005 will be a record year for revenues. We expect to continue growing our business through diversification of our customer base and process capabilities and by benefiting from the general economic recovery.”

The company also stated that it continues to move forward with the CFG acquisition. Core previously announced that CFG’s fiscal year 2004 annual sales were approximately $16 million, primarily in the heavy-duty truck market.
