Trading of Zarlink Semiconductor Common Shares Will Be Suspended from the New York Stock Exchange

OTTAWA, CANADA (NYSE: ZL) today announced that it has been advised by the New York Stock Exchange Regulation, Inc. (NYSE Regulation) that trading of the common shares of Zarlink Semiconductor Inc., ticker symbol ZL, on the New York Stock Exchange (NYSE) will be suspended prior to the opening on Tuesday, July 29, 2008.

Zarlink has advised the NYSE that its common shares will continue to be traded on the Toronto Stock Exchange (TSX), where such shares have been listed since August 13, 1979. The TSX represents in excess of 75 percent of the Company's total daily trading volume.

The decision was reached in view of the fact that the Company has fallen below the NYSE's continued listing standard regarding average share price over a consecutive 30 trading-day period of not less than US$1.00. The Company effected an action plan to address non-compliance with NYSE's continued listing standards. However, after the elapsing of the prescribed time the continued listing standard was not met and the NYSE decided to proceed with suspension and delisting.

"The technology advances in equities trading mitigates the requirement for Zarlink to continue to be listed on multiple exchanges," said Kirk Mandy, President and CEO, Zarlink Semiconductor. "This decision will not impact the financial status of Zarlink or affect the way it conducts its business."

Application to the U.S. Securities and Exchange Commission to delist the issue from the NYSE is pending the completion of applicable procedures. The NYSE noted that it may, at any time, suspend a security if it believes that continued dealings in the security on the NYSE are not advisable.
