Exhibit 99.1

Lion Group Holding Ltd. Announces Strategic Treasury Reallocation: Converting SOL and SUI Assets to Hyperliquid (HYPE) following U.S. Institutional Custody Milestone

Singapore – September 8, 2025 – Lion Group Holding Ltd. (NASDAQ: LGHL) (“LGHL” or the “Company”), a leading operator of an all-in-one trading platform, today announced its plan to exchange all of its current Solana (SOL) and Sui (SUI) assets to Hyperliquid (HYPE). This follows the launch of institutional HYPE EVM custody solutions in the U.S. by BitGo Trust Company, Inc. (“BitGo”) and aims to optimize the Company’s cryptocurrency portfolio by leveraging Hyperliquid’s high-performance Layer 1 blockchain and decentralized perpetual futures exchange capabilities.

As part of this reallocation, LGHL will employ an accumulation strategy to convert its SOL and SUI positions into HYPE over time. This approach is designed to lower the average acquisition cost by taking advantage of market volatility and accumulate HYPE at optimal prices. The strategy reflects the Company’s commitment to prudent risk management and long-term value creation in the evolving digital asset landscape.

“We believe Hyperliquid represents the most compelling opportunity in decentralized finance, with its on-chain order book and efficient trading infrastructure,” said Mr. Wilson Wang, CEO of LGHL. “By shifting our holdings from SOL and SUI to HYPE through a disciplined accumulation process, we aim to enhance portfolio efficiency and position the Company for sustained growth in the crypto sector.”

LGHL remains committed to exploring strategic opportunities within the digital asset space and will provide periodic updates as it continues to grow and manage its treasury reserve. This initiative aligns with the Company’s broader mission to provide innovative trading solutions and explore emerging technologies that benefit its corporate clients, individual traders, and retail investors.
