Core Molding Technologies Set to Join Russell 3000® Index

COLUMBUS, Ohio–(BUSINESS WIRE)–Core Molding Technologies, Inc. (NYSE MKT:CMT) (“Core Molding” or the
“Company”) is set to join the broad-market Russell 3000^®
Index at the conclusion of the Russell indexes’ annual reconstitution,
effective after the US market opens on June 26^th.

Annual reconstitution of the Russell US indexes captures the 4,000
largest US stocks as of the end of May, ranking them by total market
capitalization. Membership in the US all-cap Russell 3000^®
Index, which remains in place for one year, means automatic inclusion in
the large-cap Russell 1000^® Index or small-cap Russell 2000^®
Index as well as the appropriate growth and value style indexes. FTSE
Russell determines membership for its Russell indexes by objective,
market-capitalization rankings and style attributes.

“We are extremely pleased to be added to the Russell 3000^®
Index to raise Core Molding Technologies’ profile and visibility within
the investment community,” said Kevin Barnett, President and Chief
Executive Officer. “We look forward to the opportunity to articulate the
Core story to a broader shareholder base.”

Russell indexes are widely used by investment managers and institutional
investors for index funds and as benchmarks for active investment
strategies. Approximately $8.4 trillion in assets are benchmarked
against Russell’s US indexes. Russell indexes are part of FTSE Russell,
a leading global index provider.
