Notice Regarding the Commencement of Discussions for Advancing enish's Solana Treasury Strategy

SOL Planet Inc. ("SOL Planet") announces that it has commenced discussions with enish Inc. (Code: 3667, listed on the Tokyo Stock Exchange Growth Market, hereinafter referred to as "enish") regarding the advancement of enish's Solana digital asset treasury strategy, as detailed below.

1. Background of Discussion Commencement In recent years, initiatives for Digital Asset Treasury (DAT), which incorporates crypto assets into balance sheets, have been rapidly expanding, particularly among listed companies both domestically and internationally. However, conventional DAT models have been criticized for their high dependence on valuation gains from rising crypto asset prices and challenges in linking with continuous corporate value enhancement. SOL Planet's primary business objective is to support the realization of "DAT 2.0," which goes beyond the "holding-centric" DAT (DAT 1.0) to achieve a cycle of revenue generation and business growth utilizing digital assets. Leveraging its strengths of over four years of continuous validator operation on the Solana network and its knowledge of collaborations with major DeFi protocols and ecosystems both domestically and internationally, SOL Planet has initiated discussions with enish to support the advancement of their Solana digital asset strategy.

2. Purpose of Discussions The purpose of these discussions is for SOL Planet to provide technical and operational expertise on the Solana network to improve the effectiveness and sustainability of enish's active treasury business. Furthermore, these discussions are positioned not as a means to achieve short-term revenue, but as a strategic initiative for enish to build a medium-to-long-term digital asset management foundation while deepening its collaboration with the Solana ecosystem.

3. Main Discussion Contents (1) Provision of Solplanet White Label Validation Program The Solplanet White Label Validation Program offered by SOL Planet is an infrastructure solution for enterprises that supports the construction and operation of Solana validators under their own brand. It comprehensively supports validator design, node construction, monitoring and failure response, performance improvement, staking and delegation design, visualization of on-chain operational status, and ecosystem collaboration for acquiring delegations. In discussions with enish, SOL Planet will explore the advancement of enish's SOL staking operations, the potential for acquiring external delegations in the future, and the possibilities for validator-related businesses and white-label validation businesses.

(2) Solana Ecosystem Collaboration Support Leveraging SOL Planet's expertise in collaborating with major overseas Solana projects, Liquid Staking Tokens (LSTs), and DeFi protocols, SOL Planet will explore the potential for enish to connect with the Solana ecosystem. From a broad perspective encompassing staking, delegation, validation, and DeFi, SOL Planet will support the establishment of an operational framework that emphasizes availability, transparency, decentralization, and governance.

As of the current date, no specific business launch, service provision, revenue recognition, or partnership agreements have been decided.
