Exhibit 99.1
BitFuFu Announces November 2025 Bitcoin Productionand Operational Updates
SINGAPORE, December 5, 2025 (GLOBE NEWSWIRE) — BitFuFu Inc. (“BitFuFu” or the “Company”) (NASDAQ: FUFU), a world-leading Bitcoin miner and mining services innovator, today announced its unaudited production and mining operational updates for November 2025.
“Over the past month we accelerated sales of legacy S19 series miners and are replacing them with next-generation S21 miners. The transition created a temporary dip in total hashrate under management, but our upgrade plan is on track and positions us to mine more efficiently going forward,” said Leo Lu, Chairman and CEO of BitFuFu.
“In parallel, we have taken a deliberately conservative approach to third-party hash-rate purchases, avoiding higher-cost commitments while Bitcoin prices are under pressure. Our priority is to remain profitable across bull and bear markets, and we continue to see a very compelling long-term outlook for Bitcoin. We are also advancing opportunities to expand our hash-rate footprint globally, which we believe can further diversify our cost base and support future growth.”
November 2025 Highlights (as of November 30, 2025)
Bitcoin Holdings and Production:
Consistent with its disciplined treasury practices, the Company opportunistically sold 205 BTC in November 2025 at an average price of $107,000 to fund supplier obligations and prudently manage risk amid temporary market volatility.

| --- | --- |
Hashrate Overview:

|---|---|
| o | Self-Owned Hashrate^2^:<br> 3.7 EH/s, a decrease of 1.3 EH/s from October 31, 2025, as a result of an ongoing upgrade<br> of self-owned mining machines, where some S19 XP miners were sold and will be replaced with<br> new-generation models in the near term. |
