Vault Ventures PLC

("Vault Ventures" or the "Company")

Solana Purchase

Vault Ventures plc (AQSE:VULT), a London based technology developer focused on blockchain and fintech innovation, is pleased to announce that it has purchased Solana ("SOL"). This forms part of the Company's broader digital asset treasury strategy, as announced on 26 June 2025, which includes holdings in Bitcoin ("BTC") and Ethereum ("ETH").

Solana has been selected for its staking functionality and growing relevance within blockchain infrastructure, offering additional diversification and growth potential for the Company's treasury strategy whose primary purpose is to support the operations of the Company.

The following purchase of SOL was made:

○    Number of SOL purchased: 881.10

○    Average Purchase Price: £109.60 per SOL ($149.45)

The total assets in Treasury following the purchases above are:

○    Number of ETH: 437.843 (c.75.17%)

○    Number of BTC: 2.076 (c.15.68%)

○    Number of SOL: 881.10 (c.9.14%)

Market-to-Net-Asset-Value Ratio (mNAV)

As at 2 July 2025, the value of Vault's treasury holdings totals approximately £1,042m comprising 2.076 BTC, 881.10 SOL and 437.843 ETH. The Company's market capitalisation at the time of this announcement is approximately £3.28 million, resulting in a market-to-net-asset-value (mNAV) ratio of 3.15.

mNAV is calculated by dividing the Company's market capitalisation by its net asset value, in this calculation we have used Vault's value of its digital asset treasury following the above-mentioned purchase. This ratio provides a simple measure of how a company's market capitalisation compares to the assets it holds. A lower mNAV may indicate a closer alignment between the Company's market value and its digital asset treasury.

Chair, Brian Stockbridge commented:

ÒAdding Solana to our treasury strategy is a natural progression for Vault. Solana is a high-utility network with strong developer activity, growing institutional recognition, and a staking structure that aligns well with our yield-generating approach.

Importantly, Vault continues to maintain a disciplined structure, with its current market capitalisation reflecting an M/NAV ratio of 3.15. This in our opinion compares favourably with other AQSE-listed companies with announced digital asset treasury strategies and underscores the Board's view that Vault's valuation is well-aligned with the value of its treasury holdings.
