NobelSustainability Trust Chairman Peter Nobel and MFH CSO Wilfred Daye Join Mercurity Fintech Board

Appointmentof prestigious Nobel family leader is a major stepping stone in the convergence of traditional finance and next-gen innovation

NewYork, NY, Aug. 25, 2025 (GLOBE NEWSWIRE) — Mercurity Fintech Holding Inc. (the “Company,” “we,” “us,” “our company,” or “MFH”) (Nasdaq: MFH), a blockchain-powered fintech group and Russell 2000 Index member, today announced the appointment of Peter Nobel as Independent Director and Wilfred Daye, Chief Strategy Officer (CSO) of MFH, as Director to its Board of Directors.

Nobel, Chairman of the Nobel Sustainability Trust Foundation and a core figure of the Nobel family legacy, brings decades of leadership in global sustainability, industrial innovation, and ethical governance. He previously held senior executive roles at leading firms such as Alfa Laval and SWEP International, where he spearheaded transformative growth in clean energy, HVAC systems, and advanced materials.

Peter’s insights will support MFH’s long-term vision of aligning financial innovation with sustainability, transparency, and global institutional standards, as MFH rapidly builds a next-generation financial infrastructure at the intersection of Web3, AI, and digital capital markets. Initiatives include Bitcoin and Solana treasury strategies, AI-driven regulatory technology, and on-chain settlement for tokenized assets.

“Peter Nobel represents something truly unique in our industry – a bridge between the institutional credibility that traditional finance demands and the innovative spirit that digital assets require,” said Shi Qiu, CEO of Mercurity Fintech. “Together with our CSO, Wilfred Daye, now joining the Board, we are strengthening MFH’s governance and strategic capabilities as we build a transparent, responsible financial ecosystem.”

Since founding the Nobel Sustainability Trust in 2007-the only Nobel family-led institution dedicated to global sustainability-Peter Nobel has worked to extend Alfred Nobel’s vision of ‘benefit to humanity’ into modern challenges like climate governance and responsible capital. As the Nobel family’s most visible representative in global business, his move into digital finance marks a natural evolution of the family’s ethical legacy into the defining technologies of our time.

“The evolution of finance through blockchain and digital assets represents one of the most profound shifts in how value moves through our global economy,” said Peter Nobel. “What attracted me to MFH is their understanding that principles of transparency, sustainability, and ethical governance must guide this transformation. The same spirit that drove Alfred Nobel to establish prizes recognizing human achievement now calls us to ensure that financial innovation serves not just efficiency, but humanity’s broader interests. I’m excited to help MFH in this mission.”

“With Nobel and Daye on board, MFH gains both a trusted institutional voice and a seasoned fintech strategist.”
