BitFuFu Announces US$5 Million Share RepurchaseProgram

SINGAPORE, June 22, 2026 (GLOBE NEWSWIRE) — BitFuFu Inc. (“BitFuFu” or the “Company”) (NASDAQ: FUFU), a world-leading Bitcoin miner and mining services innovator, today announced that on June 22, 2026, its board of directors approved a share repurchase program, pursuant to which the Company may repurchase up to US$5 million worth of its Class A ordinary shares, par value $0.0001 per share, during a 24-month period starting from June 24, 2026. The share repurchase program aims to demonstrate the Company’s confidence in its long-term business prospect and to deliver value to shareholders.

The Company’s proposed repurchases may be made from time to time through open market purchases, in privately negotiated transactions, or by other means, including through the use of trading plans, intended to qualify under Rule 10b-18 under the Securities Exchange Act of 1934, as amended, in accordance with applicable securities laws and other restrictions. The timing and amount of any repurchases will depend upon business, economic and market conditions, corporate, legal and regulatory requirements, prevailing stock prices, trading volume, and other considerations. The Company’s board of directors will review the share repurchase program periodically and may authorize adjustments of its terms and size. The Company expects to utilize its existing cash and cash equivalents to fund any repurchases under the share repurchase program.

“The Board’s authorization of this share repurchase program reflects our confidence in BitFuFu’s fundamentals and growth prospects, as well as our commitment to disciplined capital allocation. While current market conditions may present short-term fluctuations in operating metrics, our solid financial position enables us to repurchase shares opportunistically while continuing to invest in key business initiatives, including expanding our global infrastructure platform and increasing hashrate capacity. We believe this balanced approach can support shareholder value while maintaining the financial strength to advance our strategic roadmap,” said Leo Lu, Chairman and CEO of BitFuFu.
