Stack BTC Plc (STAK), the UK-listed company building a Bitcoin treasury for long
-term shareholders, announces that it has completed a subscription raising gross
proceeds of £6,000 at a price of £0.01 (1 pence) per share.

The fundraise comprises a small equity participation by an investor whilst the
Company continues to develop its strategy.

As part of the fundraise, the Company will issue 600,000 warrants to the
investor on the basis of one warrant for each New Ordinary share subscribed for
under the Investment, with each warrant entitling the holder to subscribe for
one new Ordinary Share pursuant to the terms of the relevant warrant instrument.

The proceeds of the fundraise will provide additional working capital required
for the Company’s short-term requirements. The Company intends to raise further
funds in due course.

Shares in Issue and Total Voting Rights

Application will be made for the New Ordinary shares to be admitted to trading
on the Aquis Growth Market and Admission is expected to occur on 11 February
2026.

Following Admission, the Company will have 20,600,000 ordinary shares in issue,
each with one voting right. The Company does not hold any shares in treasury and
