<div align='center'>Brightstar Lottery PLC Announces Accelerated Share Repurchase Program</div>

On July 29, 2025, Brightstar Lottery PLC (NYSE: BRSL) (the “Company”) entered into an accelerated share repurchase (“ASR”) agreement with Banco Santander, S.A. (“Santander”) to repurchase an aggregate of $250 million of the Company’s outstanding ordinary shares, nominal value USD 0.10 per share, under the Company’s existing $500 million share repurchase authorization, which was announced on July 1, 2025.

Under the ASR agreement, the Company will make an upfront payment of $250 million to Santander and expects to receive, as an initial delivery of shares, a significant portion of the total number of ordinary shares deliverable to the Company. The total number of ordinary shares deliverable to the Company will ultimately depend on the average of the daily volume-weighted average prices of the ordinary shares during the term of the ASR, less a discount, and subject to possible adjustments under the ASR agreement.

Under certain circumstances, the ASR is subject to cancellation or early termination, in which case value may be owed by either party depending on, among other factors, when the ASR agreement is cancelled or
