LONDON BTC COMPANY LIMITED

Appointment of Marex as Joint Corporate Adviser and US Capital Markets Progress

London, New York, 20 January 2026 - London BTC Company Limited ("Company") (BTC: LSE, VINZF: OTCQB), the London Stock Exchange Main Market-listed bitcoin treasury and mining company with expanding operations across North America, is pleased to announce the appointment of Marex as joint Corporate Adviser and Broker, alongside an update on its US capital markets strategy.

Appointment of Marex as Joint Corporate Adviser and Broker

The Company has appointed Marex as its joint Corporate Adviser and Broker with immediate effect.

Marex is a Nasdaq-listed global financial services platform with a substantial presence across the United States, Europe and Asia, and operates across commodities, financial markets, execution, and capital markets advisory. The Company believes that Marex's appointment may provide the Company with enhanced access to strategic advisory services, particularly in relation to US capital markets, institutional investor access, and international market positioning.

The Board believes that Marex's global footprint, US capital markets experience and deep institutional relationships make it a strong partner as the Company continues to scale its bitcoin treasury and mining platform.

The Company also notes Marex's recent acquisition of Winterflood Securities, one of the UK's leading equity market maker and retail execution platform. This transaction enhances Marex's UK cash equities capabilities and strengthens its ability to support liquidity, distribution and execution for listed growth companies.

The appointment of Marex is intended to complement the Company's existing advisory and broking relationships while adding significant depth across both UK and US capital markets.

US Capital Markets and Nasdaq Planning

The Company continues to progress workstreams relating to a potential dual listing on Nasdaq, including adviser engagement, structural planning and preparatory work. The involvement of a Nasdaq-listed adviser with a substantial US footprint is expected to support this process and broaden access to deeper pools of institutional capital over time.

No formal decision has been taken regarding any additional listing, and the Company will update shareholders as appropriate.

Hewie Rattray, CEO of London BTC Company Limited, comments:

"We are deliberately building London BTC Company Limited to operate credibly across both UK and US capital markets. Appointing Marex as Corporate Adviser significantly strengthens our advisory team, particularly given their Nasdaq listing experience, US presence and institutional reach. As we continue to grow our bitcoin per share and scale our platform, we believe this positions the Company well for the next phase of its development."

The directors of London BTC Company Limited accept responsibility for this announcement.
