FOR IMMEDIATE RELEASE

6 April 2018

Fidessa group plc ("Fidessa")

New date for Shareholder Meetings

On 21 February 2018, the boards of Fidessa and Temenos announced that they had reached an agreement on the terms of a recommended all cash acquisition by Temenos, through its wholly-owned subsidiary Temenos Holdings UK Limited ("Temenos Bidco"), of the entire issued and to be issued ordinary share capital of Fidessa (the "Temenos Acquisition"). It is intended that the Temenos Acquisition will be implemented by way of a Court-sanctioned scheme of arrangement under Part 26 of the Companies Act 2006 (the "Scheme").

On 5 April 2018, the Scheme Court Meeting and the General Meeting to approve the Temenos Acquisition were adjourned in order to allow Fidessa to explore in more detail possible offers from Ion Investment Group Limited ("ION") and SS&C Technologies Holdings, Inc. ("SS&C").

Fidessa announces today that the Scheme Court Meeting and the General Meeting to approve the Temenos Acquisition will be held on 27 April 2018. Further details, including a revised expected timetable in respect of the Scheme, are set out below.

Fidessa remains in discussions with ION and SS&C about possible alternative offers for Fidessa. There can be no certainty that an offer will be made by either ION or SS&C, nor as to the terms of any offer.

Enquiries

Temenos Scheme Court Meeting and General Meeting

Action required

As described in the Scheme Document posted on 13 March 2018, the Scheme will require the approval of the Fidessa Shareholders at the Scheme Court Meeting and the passing of a special resolution at the General Meeting, and then the sanction of the Court.

The Scheme Court Meeting and the General Meeting to approve the Scheme (and the steps contemplated by the Scheme) will be reconvened to be held at 9.30 a.m. and 9.45 a.m. (or as soon thereafter as the Scheme Court Meeting has concluded or been adjourned), respectively, on 27 April 2018 at the offices of Cleary Gottlieb Steen & Hamilton LLP, 2 London Wall Place, London EC2Y 5AU. A notice (in the form of a supplementary circular) reconvening the meetings will be posted to Fidessa shareholders shortly.

If you have already submitted Forms of Proxy for the Scheme Court Meeting and/or the General Meeting and do not wish to change your voting instructions you need take no further action as your Forms of Proxy will continue to be valid in respect of the Reconvened Scheme Court Meeting and Reconvened General Meeting.

If you have submitted Forms of Proxy for the Scheme Court Meeting and General Meeting and now wish to change your voting instructions, or if you have misplaced your Forms of Proxy, you should contact Fidessa's registrars, Equiniti, on 0371 384 2898 (from within the UK) or +44 121 415 0259 (from outside the UK) to obtain new Forms of Proxy.

If you are yet to submit either or both Forms of Proxy and whether or not you plan to attend the Reconvened Scheme Court Meeting and Reconvened General Meeting, you are strongly encouraged to sign and return your Forms of Proxy (or appoint a proxy, electronically, as referred to in the Scheme Document) as soon as possible and in any event so as to be received by Fidessa's registrars, Equiniti, by the following times and dates:

· Blue Forms of Proxy for the Reconvened Scheme Court Meeting: 9.30 a.m. on 25 April 2018;

· White Forms of Proxy for the Reconvened General Meeting: 9.45 a.m. on 25 April 2018,

(or in the case of a further adjourned meeting, not later than 48 hours prior to the time and date set out for the adjourned meeting).

Further details will be included in the supplementary circular.

If you have any questions about the supplementary circular, the Scheme Document, the Reconvened Scheme Court Meeting or the Reconvened General Meeting, or how to complete the Forms of Proxy, please call Equiniti on 0371 384 2898 (from within the UK) or +44 121 415 0259 (from outside the UK).

The Scheme Document is and will remain available on Fidessa's website (www.fidessa.com) up to and including the end of the Offer Period.

Capitalised terms used but not defined in this announcement have the meaning given to them in the Scheme Document.

EXPECTED TIMETABLE OF PRINCIPAL EVENTS FOR THE TEMENOS ACQUISITION

The following indicative timetable sets out expected dates for the implementation of the Scheme. All references to times are to London time unless otherwise stated.

The following dates and times associated with the Scheme are subject to change and will depend, amongst other things, on the date on which regulatory (and other) Conditions to the Scheme are satisfied or, if capable of waiver, waived and on the date on which the Court sanctions the Scheme and the Scheme Court Order is delivered to the Registrar of Companies. Fidessa will give adequate notice of all of these dates and times, when known, by issuing an announcement through a Regulatory Information Service and on its website (www.fidessa.com). Further updates and changes to these times shall, at Fidessa's discretion, be notified in the same way.

Notes:

(1) The dates and times given are indicative only and are based on Fidessa's current expectations and may be subject to change (including as a result of changes to the timetable related to the satisfaction of the Conditions). If any of the times and/or dates above change, the revised times and/or dates will be notified to Fidessa Shareholders by announcement through a Regulatory Information Service and on its website (www.fidessa.com).

(2) The Blue Form of Proxy for the Reconvened Scheme Court Meeting may, alternatively, be handed to Fidessa's Registrars, Equiniti, or the Chairman of the Reconvened Scheme Court Meeting, at the start of the Reconvened Scheme Court Meeting (or any adjournment thereof). However, if possible, Fidessa Shareholders are requested to lodge the Blue Forms of Proxy at least 48 hours before the time appointed for the Reconvened Scheme Court Meeting.

(3) The White Form of Proxy for the Reconvened General Meeting must be lodged with Fidessa's Registrars, Equiniti, by no later than 9.45 a.m. on 25 April 2018 in order for it to be valid, or, if the Reconvened General Meeting is adjourned, no later than 48 hours before the time fixed for the holding of the adjourned meeting. If the White Form of Proxy is not returned by such time, it will be invalid.

(4) If either Fidessa Meeting is further adjourned, the Voting Record Time for the adjourned Fidessa Meeting will be 6.30 p.m. on the date which is two days before the date set for the adjourned Fidessa Meeting.

(5) To commence at the time fixed or, if later, immediately after the conclusion or adjournment of the Reconvened Scheme Court Meeting.

(6) The Court Hearing to sanction the Scheme is expected to be held no later than 14 days after the satisfaction or waiver (where applicable) of Condition 3(d), as set out in Part IV (Conditions and Certain Further Terms of the Scheme and the Acquisition) of the Scheme Document. Any references to "D" or to a day after "D" are references to a Business Day.

 (7) This date will be the date on which the Scheme Court Order is delivered to the Registrar of Companies. The Effective Date of the Scheme is expected to occur in the second quarter of 2018.

 (8) This is the latest date by which the Acquisition may become Effective unless Fidessa and Temenos Bidco agree, and (if required) the Court and the Panel allow, a later date.
