Jos Dijsselhof appointed new CEO of SIX

The Board of Directors of SIX have announced strategic and organizational changes so as to
strengthen the competitiveness of SIX and the Swiss financial centre in a changing business
environment. SIX will focus on infrastructure services for its shareholders and the financial
centre in securities, payments services and financial information. SIX will also increase its
commitment to innovation by launching a CHF 50 million venture fund and establishing
dedicated units to develop services to cover specific shareholder requirements.

Jos Dijsselhof, who will begin his role as CEO of SIX from the start of 2018, is an experienced
manager and succeeds Urs Rüegsegger, who announced in May that he would step down.
SIX represents the joint, successful commitment of Swiss banks to sustaining a strong Swiss
financial centre. Since its foundation ten years ago, the environment SIX operates in has changed
fundamentally (in terms of technology, new competitors, regulation and pressure on margins). As
part of a strategy and organization review, the Board of Directors has, since the beginning of the
year, been analysing the changing requirements that banks and the market are placing on SIX. The
Board of Directors has taken a clear stance in favour of a strong, shared financial market
infrastructure in Switzerland and has adopted a number of strategic and organizational measures
aimed at perfectly equipping SIX for the future.

In this realignment, SIX will focus consistently on infrastructure services for its shareholders and the
financial centre in securities, payment services and financial information, which form the company’s
core business. In future, the company will operate on the market exclusively under the “SIX” brand.
The changes will create synergies and efficiencies that boost the attractiveness of the offering of SIX
to clients and shareholders. This approach will create the perfect environment to develop innovative
services which can be quickly introduced to the market.
The main elements of this realignment are:

 The bundling of all activities in the securities business. The merger of exchange trading and
post-trading areas into one organizational unit, with all securities trading services now provided
from a single source.
 The reorganization of the payments business. SIX is creating a competence centre for
operations, development and greater innovation in Swiss payments. This will include the
infrastructure for interbank payments, for connections to the SEPA region and for card-based
and mobile payments. For e-bills and direct debits, the collaboration with PostFinance to
standardize and bundle infrastructure will be continued.
 The card business (merchant acquiring and international card processing) will be separated from
the core organization and, with the aim of creating a leading European provider, further developed as part of a strategic partnership. Integration of the latest acquisitions (Aduno, VÖB-
ZVD) will go ahead as planned.

 The consolidation of the strong market position of SIX in the data business, in particular in
international reference data. SIX intends to utilize the resulting synergies to provide even better
solutions to respond to the demand from banks for high quality at attractive conditions.
 The establishment of an innovation unit. Aside from bundling its own innovation projects, SIX
will also establish a CHF 50 million venture fund to promote innovation within Switzerland’s
financial centre. This new innovation unit will also develop services to cover specific
shareholders requirements, which can then be hived off in collaboration with the relevant
shareholders.

These measures are due to be fully implemented in the second quarter of 2018. Until then, SIX will
continue to operate with its current organization and business models.

Romeo Lacher, Chairman of the Board of Directors: “SIX has developed very successfully since its
inception. What we are doing now is setting the course for SIX to continue to play a major part in
assuring the quality and success of the Swiss financial centre.”

To implement these changes, the Board of Directors of SIX has appointed Jos Dijsselhof CEO with effect from 1 January 2018. He succeeds Urs Rüegsegger, who announced in May 2017 that he would be retiring. A Dutch citizen, Jos Dijsselhof, 52, holds degrees in computer science and Business Administration, and has a long track record in international management in the financial sector. He has previously held positions at ABN Amro Bank, Royal Bank of Scotland and ANZ Australia & New Zealand Banking Group in various countries, including Hong Kong and Singapore. His most recent role was Chief Operating Officer (2014–June 2017) and CEO ad interim (2015) for Euronext in Amsterdam. During his career, Jos Dijsselhof has successfully headed several change projects and gained a wealth of experience in securities and financial data, as well as the payments business, so he is fully familiar with the business models of SIX.

Romeo Lacher, Chairman of the Board of Directors: “I am delighted to have found in Jos Dijsselhof
an experienced manager for SIX with strong leadership qualities and an outstanding track record. I
would also like to thank Urs Rüegsegger for his service and dedication. Under his leadership, SIX
was able to lay a solid
