RE:

Notice of Change of Financial Year-End pursuant to Section 4.8 of National Instrument 51-102 – Continuous Disclosure Obligations (“NI 51-102”)

1.	Reporting Issuer Change of Financial Year-End

Gildan Activewear Inc. (“Gildan”) hereby provides notice pursuant to Section 4.8 of NI 51-102 that it has changed its financial year-end from the first Sunday following September 28 to the closest Sunday to December 31.

2.	Reason for the Change

The change in year-end recognizes that the seasonality of the overall consolidated sales revenues for Gildan is changing due to the increasing importance of the Branded Apparel segment. Gildan's business planning cycle is becoming more aligned with the calendar year, and this change will provide better visibility on retail program placements and cotton fixations. In addition, the change in year-end will be better aligned with Gildan's industry comparables.
