Dear Directors,

As long-term owners of Gildan, we are deeply disappointed that the Board of a major corporation and a true Canadian success story has chosen to pursue a strategy that we believe is aimed at disenfranchising its shareholders by denying them the opportunity to allow their voices to be heard. It is a simple request – hold the requisitioned meeting of Gildan shareholders (the “Meeting) as you are required by statute to do, to allow shareholders to vote on the composition of the Board.

The Company’s latest disclosures suggest it may seize on a purported “foot fault”, under the guise of protecting “shareholder value”, to deny shareholder Browning West’s requisition for a Meeting. But in reality, your response is nothing more than an attempt to entrench yourselves. The Board is well aware of the widespread loss of confidence in its stewardship, made evident in the unprecedented public and private statements by a substantial percentage of Gildan’s shareholders.

You are entitled to make your case as to the reasons behind your ill-conceived, value destructive decision to terminate Gildan’s founder and CEO of over 20 years. But you are not entitled to stop the shareholders from voting on who they wish to represent them on the board of their company. And while we respect your right to communicate your reasons, we urge you to conduct yourselves in a professional manner. Your current destructive PR campaign of inferences and innuendo is, quite frankly, embarrassing to the Company and to each of you. For the sake of each of your reputations, and for the sake of the Company, we urge you to end it.

Members of the Board, do the right thing – call the Meeting without delay. Allow the shareholders, the owners of the Company, to exercise their statutory rights to vote for their representatives. You have a legal and moral responsibility to act as independent fiduciaries for shareholders, even when those shareholders disagree with you and seek to have you replaced. There is still time to change course and preserve your professional reputations. Do not let your advisors push you into an ugly and costly proxy fight that you are unlikely to win.

Sincerely,

Turtle Creek Asset Management
