Catenai PLC (AIM: CTAI), the AIM-quoted provider of technology and digital solutions, is pleased to announce that it has made a further investment of £250,000 (the "Investment") into Alludium Ltd ("Alludium), a developer of a no-code AI Agent Operating System.

The Investment is part of a £1 million fundraising by Alludium at a pre-money valuation of £9 million, which will increase Catenai's shareholding from approximately 13% to 16.1%. The Investment follows Alludium's successful public-commercial launch, announced on 10 March 2026, with the funds to be used for marketing initiatives and to further enhance the Alludium platform.

Alludium is a pre-revenue company and its first full year results have been published and report a loss of approximately £33,000 for the year ended 31 August 2024.

The Investment will be made from existing cash reserves and Catenai confirms that it continues to have sufficient cash resources to cover corporate costs beyond the next 18 months from the date of this announcement.

Company Update

Furthermore, Klarian Limited ("Klarian"), a company to which Catenai provided a £450,000 unsecured convertible loan note facility, will provide an update in early April 2026 and will be followed by a presentation via the Investor Meet Company platform. As announced on 5 January 2026, Klarian is due to repay Catenai the £624,250 under the convertible loan note agreement announced on 25 April 2024, and related fees by 31 March 2026, with an additional fee of £74,910 as part of an arrangement if the repayment was to occur after 28 February 2026.

The Company is also pleased to advise that its client, Charlton Athletic Community Trust, has engaged the Company to undertake a new technology services project. The Company will receive a modest cash fee for the project.

Separately, the Board is reviewing the Company's Bitcoin treasury policy, having not yet made any purchases, and will update the market in due course.
