**BitFuFu Announces September 2025 Bitcoin Production and Operation Updates: Bitcoin Holdings Increasing to 1,959 BTC**

● BitFuFu held 1,959 BTC as of September 30, 2025, an increase of 60 BTC from August 31, 2025.

SINGAPORE, October 6, 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 operation updates for September 2025.

"We increased our Bitcoin holdings to 1,959 BTC, up 60 BTC from the prior month," said Leo Lu, Chairman and CEO of BitFuFu. "We are executing our treasury strategy to accumulate BTC through two levers: efficient self-mining, driven by low-cost power and next-generation miners, and disciplined, opportunistic Bitcoin purchases. Together, these actions position us to continue compounding BTC holdings over time."
