Signet Jewelers Limited ("Signet" or the "Company") (NYSE:SIG) today announced that its Board of Directors ("Board") has appointed Jeffrey Gennette to the Board, effective May 6, 2026. A former Chairman and Chief Executive Officer of Macy's, Inc., Mr. Gennette brings more than four decades of leadership experience at one of the world's most recognized omnichannel retailers, further strengthening Signet's Board as the Company continues to execute on its Grow Brand Love strategy.

Mr. Gennette has been appointed to the Board's Human Capital Management and Compensation Committee and the Finance Committee, bringing deep expertise across merchandising, marketing, digital transformation, and store operations to support Signet's long‑term growth priorities and capital allocation decisions.

"Signet's Board is committed to ongoing refreshment and we are delighted to welcome Jeff as a director," said Helen McCluskey, Chair of the Board. "Jeff is a highly respected retail leader who brings a deep familiarity with the jewelry category and a proven track record of leading large, complex consumer businesses through transformation. His perspective on building brands, engaging customers across channels, and driving operational excellence will be invaluable as we advance our strategy."

"Jeff's experience leading one of the largest omnichannel retailers in the U.S. brings powerful insight to Signet," said Signet CEO J.K. Symancyk. "As we continue to strengthen our brands, enhance our digital and store experiences, and grow share in a dynamic retail environment, Jeff's guidance, passion for jewelry, and expertise will be a tremendous asset to our team and our Board."

The Company also disclosed that Nancy Reardon, who has served as a director since March 2018, has informed the Board that she will not stand for re-election at the Annual General Meeting. The Board has been expanded to 12 directors following Mr. Gennette's appointment and will be reduced to 11 directors immediately following the departure of Ms. Reardon at the conclusion of the Annual General Meeting on June 26, 2026.

"We are deeply grateful to Nancy for her dedicated service and contributions over the past several years, including as Chair of the Board's Human Capital Management and Compensation Committee," said McCluskey.
