capAI to commence trading today in the US on OTCQB Venture Market

capAI (LSE: CPAI) is pleased to announce that trading in the Company's ordinary shares of nominal value £0.0001 each ("Ordinary Shares") will commence today, at market open on the OTCQB Venture Market ("OTCQB") in the US at 2.30 p.m. (GMT) / 9.30 a.m. (Eastern Standard Time).

The Ordinary Shares will trade on OTCQB under the ticker "CPIQF".

There is no associated capital raise with this cross trade on OTCQB and the Ordinary Shares will continue to trade on the Company's primary listing market, the main market for listed securities of London Stock Exchange plc ("Main Market") under the ticker "CPAI".

OTCQB is provided through OTC Markets Group Inc. ("OTC Markets"), located in New York, US.

OTC Markets operates the world's largest electronic interdealer quotation system for US broker dealers and offers multiple media channels to increase the visibility of OTC-listed companies. OTCQB is a well-established market designed to provide enhanced visibility and liquidity for international companies seeking to broaden their US investor base. Recent market activity on OTCQB and analyst sentiment has shown a strong US investor interest in artificial intelligence ("AI") companies. Trading on OTCQB is expected to enhance the Company's international presence, liquidity and access to additional AI-focused investors.

The OTCQB offers transparent trading in entrepreneurial and development stage companies that have met a minimum bid price test, are current in their financial reporting and have undergone an annual verification and management certification process. The Ordinary Shares will be available via the OTCQB to US investors during US working hours and priced in US Dollars, and thus this cross-listing has the potential to enable greater liquidity in the Ordinary Shares on the Main Market by easing cross-border trading for potential US investors.

Richard Edwards, Executive Chairman of capAI, commented:

"Our OTCQB quotation broadens capAI's access to the US investor community with minimal additional costs, enhancing our visibility, liquidity, and alignment with global AI capital markets."
