Proposed Change of Name & Notice of GM

Castle Street Investments plc

("Castle Street", "the Company" or "the Group")

Proposed Change of Name &

Notice of General Meeting

Castle Street today announces the Company's intention to change its name to CORETX Holdings plc. The proposed name change is subject to shareholder approval at a General Meeting which will take place at 11.00 a.m. on 11 April 2016 at the offices of DAC Beachcroft LLP, 100 Fetter Lane, London EC4A 1BN.

A copy of the Circular and Notice of the General Meeting has been posted to shareholders and will be made available on the Company's website at www.castlestreetinvestments.com.

 Presently there are three different company names in use being Castle Street Investments, Selection Services and C4L. This can be confusing for both customers and prospects, and does not support the strategy of presenting a unified portfolio of products and services from Selection Services and C4L to the market. Accordingly the Board believes it would be more effective to go to market under one brand.

In addition to this, Castle Street Investments has no connection with Castle Street and having invested in two ICT companies in January and February 2016 its principle activities are the provision of Managed IT, Network and Hosting Services to Public and Private Companies.

At the core of the Company's activities is the network built by C4L limited, CORETX, which offers clients fast access to their data across networks managed by the Group. The Directors therefore feel it would be appropriate to change the name of the ultimate parent company to CORETX Holdings plc and go to market under the single brand name CORETX.

Subject to shareholder approval, Selection Services Limited will be renamed CORETX Manage Limited and C4L Limited will be renamed CORETX Connect Limited and all other Group entities will adopt the CORETX name.
