Browning West, LP (together with its affiliates, “Browning West” or “we”), which is a long-term shareholder of Gildan Activewear Inc. (NYSE: GIL) (TSX: GIL) (“Gildan” or the “Company”) and beneficially owns approximately 5.0% of the Company’s outstanding shares, today announced that its slate of director candidates released a presentation detailing its five-pillar plan to increase Gildan’s share price to more than $60 USD by the end of 2025 and more than $100 USD within the next five years. Browning West’s slate is releasing its operating plan now so that shareholders can understand the Company’s strong standalone prospects under our slate’s leadership relative to an outcome that likely undervalues the Company under the current Board of Directors’ reactionary sale process.

As a reminder, Browning West is seeking to elect eight highly qualified and independent director candidates to Gildan’s Board of Directors at the Annual Meeting of Shareholders on May 28, 2024. Browning West’s director candidates possess strong track records of value creation, expertise in successful succession planning, relevant industry and governance experience, as well as proven management and board service pedigrees in Canada and the U.S.
