TMX Group Limited has  announced executive changes, including new
strategic and expanded responsibilities for several members of the company’s senior management team.

“Today marks an important milestone for TMX Group as we continue to position our organization to achieve sustainable, long-term success,” said Lou Eccleston, Chief Executive Officer, TMX Group.

“Over the past two years, a dynamic new senior management team has taken shape at TMX Group. In our constantly-evolving marketplace, we are leveraging the individual strengths, unique talents, impressive tenure and diverse expertise we have among our leadership group to embrace innovation and seize opportunities to grow into the future.”

The following changes are effective immediately:

In recognition of his strong track record for driving innovation and executing significant change
initiatives in his time as President and CEO of Global Enterprise Services, Jean Desgagné will now
move into the newly created position of President and CEO, TMX Global Solutions, Insights and
Analytics Strategies.

The mandate for this new leadership position is to implement and oversee a cohesive TMX
enterprise approach to innovative technology and data driven solutions. The purpose is to enrich
the client experience across TMX’s vast capital markets community by providing ready access to
benchmark data and analytics products. Jean and his team will work in collaboration across TMX’s
business areas to develop and deliver solutions and strategies that benefit the organization at
large. Jean assumes oversight of the existing Market Insights business.
Jean will continue to report directly to Lou Eccleston and sit on the TMX Executive Committee.

With Jean’s new mandate, John McKenzie will now add to his current role as Chief Financial Officer (CFO) and responsibility for TMX Group’s finance function, by taking on administrative oversight of TMX Group’s equities, fixed income and derivatives clearing businesses. Glenn Goucher continues in his role as the head of The Canadian Depository for Securities Limited (CDS) and the Canadian Derivatives Clearing Corporation (CDCC), reporting to the boards of the two clearing houses.

An employee of the company for seventeen years, Mr. McKenzie’s TMX Group career includes
senior roles in finance as well as serving as President of CDS. He will continue to report to Lou
Eccleston and sit on the TMX Executive Committee.

Cheryl Graden’s mandate will be expanded to include oversight of enterprise risk management,
as Senior Vice President, Group Head of Legal and Business Affairs, Enterprise Risk Management
and Government Relations.

Cheryl joined the company in 2004, and held senior roles in the Calgary and Toronto offices,
before being promoted to the TMX Executive Committee in 2015. Cheryl will continue to report
to Lou Eccleston and sit on the TMX Executive Committee.

Jay Rajarathinam, who joined TMX Group from NYSE/Intercontinental Exchange in July, 2016, as
Chief Information Officer, will be promoted to the TMX Executive Committee and will now report
directly to Lou Eccleston.

In addition to the above changes, Eric Sinclair, President, TMX Market Insights has announced that he is retiring at the end of August. Over the past 14 years with TMX Group, Mr. Sinclair has made significant contributions to the company. He led the growth of the fledgling data business by establishing a strong client focus, developing new products and services and implementing a professional sales force, while applying highly effective fiscal management.

“On behalf of The Board of Directors and the entire team at TMX, I want to thank Eric Sinclair for his years of dedicated service to TMX Group and acknowledge his impressive track record of success in building TMX’s Datalinx and Market Insights business,” said Mr. Eccleston.
