What Stack BTC does
Stack BTC PLC is a UK-listed Bitcoin treasury company on the Aquis Stock Exchange Growth Market (ticker: AQSE: STAK), headquartered in London. Founded in 2025 as a successor to Kasei Digital Assets PLC, the company operates a dual-engine model combining an M&A engine — acquiring established, profitable, cash-generative businesses across the Bitcoin economy (exchanges, payments, custody, mining, pensions, hedge funds, asset management, brokerage) — with a Bitcoin engine that recycles 100% of acquired-business retained earnings into a Bitcoin treasury held primarily in multi-signature cold storage. The company measures success using a proprietary 'Bitcoin per Share' (BTC/s) metric and M/NAV ratio, with the explicit goal of growing BTC backing per share without issuing new shares for operational accumulation.
As of April 2026, Stack BTC holds 68.19 BTC (current value approximately £3.24M at an average cost of £53,526.95 per BTC) against a market capitalization of roughly £5.83M, with 87.38 million shares outstanding. The company has completed three equity funding rounds in early 2026 totaling approximately £4.18 million, with notable participation from Executive Chairman Kwasi Kwarteng (former UK Chancellor of the Exchequer, ~5.4% stake), founder and CSO Paul Withers (£620,000 commitment), Nigel Farage (6.31% stake through Thorn In The Side Ltd), and strategic investor Blockchain.com (an FCA-registered crypto business). Marketing and investor distribution is conducted through the public Aquis listing (accessible via UK brokerages and ISA/SIPP wrappers), a comprehensive investor centre, educational content via the Learning Hub, and extensive earned media coverage across Financial Times, BBC, Reuters, Bloomberg, Forbes, and Sky News.
The business model depends on continued public equity issuance to fund acquisitions and direct Bitcoin purchases, combined with operational cash flow from acquired businesses to compound BTC per share over time. The company has not yet completed any operating-business acquisitions, and revenue is not disclosed. Notable risks include a pending FCA market abuse investigation request from the Liberal Democrats over Nigel Farage's promotional activities while holding equity, a -11.3% unrealized loss on the Bitcoin treasury, and a recent CEO transition from founder Jai Patel to public-market operator David Galan.

Product overview
Stack BTC PLC operates as a single unified Bitcoin treasury product — a UK Aquis-listed investment vehicle that acquires established, profitable, cash-generative businesses and channels their retained profits into a Bitcoin treasury.

The product is structured around the 'Stack Model' — a four-step compounding cycle: Acquire, Operate, Recycle, Compound — designed to grow Bitcoin per Share without diluting existing shareholders.
