Madeco's ADR Program Termination

FOR IMMEDIATE RELEASE

MADECO ANNOUNCES INTENT TO DELIST
FROM NYSE AND TERMINATE ITS ADR PROGRAM
IN THE UNITED STATES


(Santiago, Chile, June 23, 2009) Madeco S.A. (“Madeco” or the ”Company”) (NYSE ticker: MAD) announced that its Board of Directors at its meeting yesterday resolved to voluntarily delist the Company’s ADSs from the New York Stock Exchange (the “NYSE”), terminate its ADR program with the Bank of New York Mellon, as depositary and eventually deregister with the Securities and Exchange Commission (the “SEC”).

The Board’s rationale for terminating the ADR program and delisting from the NYSE is based on a number of factors, the most important being:

Madeco’s common stock will continue to trade on the Santiago Stock Exchange, the Bolsa de Valores de Valparaiso and the Bolsa Electronica de Chile.

The Company is working with the NYSE and the Bank of New York Mellon to create a timeline for the delisting and termination. Madeco will issue a press release when the timeline is finalized.

Upon termination of the ADR program, if the Company can certify that there are fewer than 300 U.S. security holders, the Company intends to deregister and terminate its reporting obligations.

Notwithstanding the termination of the ADR program and delisting from the NYSE, Madeco will continue to comply with SEC reporting requirements until its securities are deregistered.
