|99.1        |  | Press Release dated May 8, 2003, announcing financial
        results for the quarter and year ended March 28, 2003 (furnished pursuant
        to Item 12 of Form 8-K, under Item 9 of this report).

|Item 9.  Regulation FD Disclosure.
|----------------------------------



|Pursuant to Exchange Act Release 34-47583,
Zarlink Semiconductor Inc. (Zarlink  or the Company) is
furnishing the information required by Item 12 of Form 8-K,  Results of Operations
and Financial Condition, under this Item 9.
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|Zarlink has issued a press release announcing
its financial results for the  quarter and year ended March 28, 2003, and a copy of the
press release is being  furnished as Exhibit 99.1 to this report and incorporated herein
by reference.  The press release contains disclosure of cash assets (comprised of cash,
cash  equivalents, short-term investments and restricted cash). The combination of  cash,
cash equivalents, short-term investments and restricted cash is not a  measure of cash or
cash flow calculated in accordance with accounting principles  generally accepted in the
United States (GAAP). Attached as a supplementary  schedule to the press release is a
detailed reconciliation of the Companys  calculation of combined cash, cash equivalents,
short-term investments and  restricted cash. The Company believes that this supplementary
measure allows it  to more effectively manage its total cash assets. However, this
measure of cash,  cash equivalents, short-term investments and restricted cash combined
does not  have any standardized meaning prescribed by GAAP and is therefore unlikely to
be  comparable to similar measures prescribed by other companies. This measure  should
not be considered as a substitute or alternative for the Companys  consolidated
statement of cash flows.

Company is furnishing the  information required by this Item 12 under Item 9 of Form 8-K,
