Further re Acquisition of Opus Technology Group Limited

On 2 March 2015, Castleton (AIM: CTP) announced the acquisition of Opus Technology Group Limited ("Opus") the provider of software solutions to the social housing market (the "Acquisition").

Opus has performed strongly since Acquisition with 6 new customers having signed orders with a total order value of £0.5 million. In the year to 30 September 2015 Opus achieved £0.2 million of EBITDA, representing an increase of over 300% when compared to the previous 12 month period. The earn-out that was put in place at the time of the Acquisition has therefore been achieved and as a result, £0.4 million of convertible loan notes ("Loan Notes") have been issued to the vendors of Opus. Furthermore, the Company will pay £0.1 million in cash to the vendors; £0.05 million in January 2016 and £0.05 million in January 2017.

The Loan Notes can be redeemed in cash or converted into new ordinary shares of 2 pence each in the capital of Castleton ("Ordinary Shares") at 40 pence per Ordinary Share in various tranches; £0.15 million on 30 September 2016, £0.15 million on 30 September 2017 and £0.1 million on 30 September 2018. The new Ordinary Shares arising from conversion of the Loan Notes will be subject to a 12 month orderly market agreement.
