Management Comments

• Edward Chin, Founder and CEO of Parataxis Holdings, and Co-Founder & CEO of Parataxis Capital, stated: 'Following the recent transaction that created our franchises inaugural Bitcoin treasury platform, Parataxis Korea, Inc., we are excited to announce Parataxis ETH, Inc. as an independent, differentiated Ethereum treasury platform that will bridge traditional institutional finance and the on-chain digital economy of Ethereum.'
• Edward Chin also noted: 'Ethereum continues to play a central role in major use cases such as stablecoins, decentralized finance, and gaming, supported by growing institutional participation. With this Transaction, the Parataxis Holdings team is proud to bring the two most dominant digital assets in Bitcoin and Ethereum to the South Korean public markets.'
• Michael Lee, incoming CEO of the Company, commented: 'Building on the foundation established by Parataxis Koreas Bitcoin treasury, we believe the natural evolution for institutional capital is to further expand into productive digital assets. While Bitcoin serves as the premier store of value, Ethereum represents the engine of the digital economy.'
• Michael Lee further added: 'We see South Korea as the ideal market to pioneer this dual-pillar approach. Our mandate is to capture the unique utility and yield-bearing properties of the Ethereum ecosystem to provide our shareholders with diversified and institutional-grade exposure that complements existing digital asset strategies.'

Industry Context

This transaction signifies a strategic expansion into the digital asset sector, specifically targeting the Ethereum ecosystem, following a previous move into Bitcoin treasuries. It positions Parataxis to capitalize on the growing institutional interest in digital assets and blockchain technology, particularly in South Korea, which is identified as an ideal market for this 'dual-pillar approach.' The move reflects a broader trend of traditional financial entities seeking structured exposure to cryptocurrencies beyond just Bitcoin, recognizing Ethereum's role in decentralized finance (DeFi) and the broader digital economy.

Comparison to Industry Standards

• The creation of South Korea's first Ethereum-based treasury platform listed on public markets sets a new benchmark for digital asset integration within traditional financial structures in the region.
• The 'dual-pillar approach' of establishing both Bitcoin and Ethereum treasury platforms differentiates Parataxis from many single-asset focused crypto investment vehicles, offering a more diversified exposure similar to broader digital asset funds.
• The involvement of US-based institutional investors with significant experience in digital asset management aligns with global best practices for bringing institutional rigor to the nascent crypto investment space, comparable to firms like Grayscale or Fidelity Digital Assets in their structured product offerings.
