HOW TO ACCESS THE MEETING MATERIALS

We are using the notice-and-access rules permitted by Canadian securities regulators to deliver the materials for our 2023 annual and special meeting of shareholders to our registered and non-registered shareholders. This includes the 2023 management information circular and our audited annual consolidated financial statements for the year ended January 1, 2023. These documents are available on our website (www.gildancorp.com) as well as on SEDAR (www.sedar.com) and EDGAR (www.sec.gov). Online access to the materials reduces paper and mailing costs.

Your package includes a copy of this notice and a proxy form (if you are a registered shareholder) or a voting instruction form (if you are a non-registered or beneficial shareholder, unless you have elected to receive the form electronically). If you are a non-registered shareholder and object to your intermediary disclosing your share ownership information to us, you will not receive these materials unless your intermediary assumes the cost of delivery.

If you would like to receive a printed copy of our 2023 management information circular and 2022 audited financial statements before the meeting, please call 1-866-964-0492 (toll-free in North America) or 1-514-982-8716 (outside North America) and a copy will be sent to you free of charge
