Mercurity Fintech Announces $800 Million FinancingPlan for Bitcoin Treasury; Achieves Preliminary Inclusion in the U.S. Russell 2000 Index

New York, NY, June 11, 2025 (GLOBE NEWSWIRE) — Mercurity Fintech Holding Inc. (the “Company,” “we,” “us,” “our company,” or “MFH”) (Nasdaq: MFH), a digital fintech group, today announced its plans to raise $800 million to establish a long-term Bitcoin treasury reserve. Through this fundraising effort, MFH aims to leverage its established expertise in blockchain-driven financial infrastructure to strategically acquire and manage Bitcoin assets. The Company also plans to integrate these holdings into its digital reserve framework through blockchain-native custody, staking integration, and tokenized treasury management services.

Additionally, through this fundraising effort, the Company intends to systematically build a Bitcoin reserve position and implement an integrated digital asset treasury framework. This will involve deploying institutional-grade custodial infrastructure, blockchain-native liquidity protocols, and staking-enabled capital efficiency tools. The objective is to transition a portion of the Company’s treasury into a yield-generating, blockchain-aligned reserve structure that reinforces long-duration asset exposure and balance sheet resilience.

“We’re building this Bitcoin treasury reserve based on our belief that Bitcoin will become an essential component of the future financial infrastructure,” said Shi Qiu, CEO of the Company. “We are positioning our company to be a key player in the evolving digital financial ecosystem.”

Concurrently, according to FTSE Russell’s preliminary 2025 annual reconstitution list, the Company is poised to be included in the broad-market Russell 3000^®^and Russell 2000^®^ Index, representing an upgrade from its prior classification within the Russell Microcap Index. The index reclassification and upgrade could broaden the Company’s exposure to institutional investors, including those managing index-linked and actively managed funds. Furthermore, the Company believes that such inclusion signals to the market that MFH is demonstrating consistent execution capability and growing relevance of its blockchain-based infrastructure strategy within the public markets.

“Moving from the Russell Microcap to the Russell 2000 shows that investors recognize the value we are creating in blockchain finance,” Qiu added. “Our Bitcoin treasury reserve initiative is the next logical step in this evolution.”
