Item 8.01 Other Events. Accelerated Share Repurchase Agreement As part of its previously announced share repurchase plans, on September 10, 2026, Signet Jewelers Limited (the “Company”) entered into a master confirmation and supplemental confirmation (collectively, the “ASR Agreement”) with JPMorgan Chase Bank, National Association (“JPMorgan”) to repurchase $125 million of the Company’s common shares (the “Common Shares”). Under the ASR Agreement, the Company made a payment of $125 million to JPMorgan on September 11, 2026 and received an initial delivery of approximately 1,023,000 Common Shares on September 11, 2026. The total number of Common Shares that the Company will repurchase under the ASR Agreement will generally be based on the average of the daily volume-weighted average prices of the Common Shares during the calculation period under the ASR Agreement, less a discount, subject to adjustments upon the occurrence of certain events pursuant to the terms of the ASR Agreement. Upon final settlement of the transactions under the ASR Agreement, JPMorgan may be required to deliver additional Common Shares to the Company, or, under certain circumstances, the Company may be required to deliver Common Shares or make a cash payment to JPMorgan. Final settlement of the transactions under the ASR Agreement is expected to occur between September 25, 2026 and December 2, 2026, subject to postponement, adjustment, cancellation or early termination upon the occurrence of certain events as provided in the ASR Agreement. Upon completion of the ASR Agreement, the Company will have approximately $575 million in share repurchase authorization remaining under its 2017 Share Repurchase Program, subject to any further repurchases that are made during the term of the ASR Agreement, and additional repurchases may be made through additional accelerated share repurchase programs, open market purchases, through 10b5-1 plans, through block trades or otherwise for programmatic and opportunistic repurchases. The timing, manner, price and amount of any share repurchases will be determined by the Company at its discretion and will be subject to economic and market conditions, stock prices, applicable legal requirements and other factors.
