News Release Details

PITTSBURGH, PA, Jul 01, 2009 (MARKETWIRE via COMTEX) -- Koppers Holdings Inc. (NYSE: KOP) announced today that it filed a shelf registration statement on Form S-3 with the Securities and Exchange Commission, which, if and when declared effective, will permit the Company, from time to time, to offer and sell up to $325 million of debt securities, equity securities and other financial instruments. No securities may be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. The shelf registration statement will provide the Company with greater flexibility to raise capital to take advantage of potential opportunities such as debt refinancing or acquisitions. When it becomes effective, the new shelf registration statement will replace the Company's previously filed shelf registration, which will expire on September 7, 2009. The Company does not currently have any plans to make any offers or sales under the new shelf registration statement. Once the registration statement becomes effective, the terms of any future offering pursuant to the registration statement would be established at the time of the offering.

This press release shall not constitute an offer to sell or a solicitation of an offer to buy nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

A copy of the prospectus included in the registration statement may be obtained on the SEC's website at www.sec.gov subsequent to the actual filing. In addition, the Company would file a prospectus supplement with the SEC in connection with any offering under the shelf registration statement. The information on the Company's web site is not a part of the registration statement, the prospectus or any prospectus supplement which may be issued under the registration statement.
