CIBC announces Senior Executive Leadership Changes
Enhancing connectivity and
collaboration to accelerate momentum
TORONTO, May 28, 2026 /CNW/ - CIBC (TSX: CM)
(NYSE: CM) today announced senior leadership changes to its Group Executive Leadership Team. These changes will position the bank to further
leverage its purpose-led and client-focused team and strong North American platform to accelerate execution, building on the bank's strong
business performance and clear momentum.
"Across each of our businesses in Canada, the
U.S., and globally, the disciplined execution of our strategy and a deep commitment to our clients have driven strong business results
across our bank," said Harry Culham, President and CEO of CIBC. "The changes we are announcing today are focused on accelerating
our progress as a client-focused, connected, and performance-driven bank that creates value for all our stakeholders."
The following changes are effective May 28, 2026:
Strategic Business Units
These changes will reinforce the connectivity that
has become a clear differentiator for CIBC in serving clients across North America and around the world.
- Susan Rimmer has been appointed Senior Executive Vice-President
and Group Head, Commercial Banking, as she continues to lead Commercial Banking in Canada, and also assumes accountability for Commercial
Banking in the U.S., as well as the Office of the CEO (OCEO).
"Susan is recognized for her client-focused approach," said Mr. Culham. "Commercial enterprises are at the heart of
economic growth, and we're committed to building on our legacy as the bank of commerce to help these businesses thrive. Bringing together
our Commercial Banking business on both sides of the border will further our ability to provide our clients with the solutions, insights,
and advice they need to succeed."
- Eric Belanger has been appointed Senior Executive Vice-President
and Group Head, Wealth Management, as he assumes accountability for Wealth Management in Canada and the U.S., including Global Asset Management,
U.S. Private Wealth, Wood Gundy, Private Banking & Family Office, Investor's Edge, and CIBC Private Investment Counsel.
"Eric has spent more than 30 years with our bank in a range of leadership roles and has a strong track record of building innovative
solutions, deepening client relationships, and delivering growth," said Mr. Culham. "Aligning our North American Wealth
businesses will strengthen connectivity and collaboration as we bring the best of our bank to clients, and support continued growth in
Canada and the U.S."
- Kevin Li will continue in his role as Senior Executive
Vice-President and Group Head, U.S. Region, and President and CEO, CIBC Bank USA.
"Kevin will continue in his current role overseeing our U.S. Region as we leverage our connectivity across businesses to deepen and
expand client relationships," said Mr. Culham. "Kevin's exceptional client-focus, relationships across the U.S., Canada,
and Europe, and his disciplined execution will be invaluable as we further scale our growth in the U.S. across Commercial Banking, Capital
Markets, and Wealth Management."
CIBC will have four business segments for financial
reporting purposes (in addition to Corporate and Other): Canadian Personal and Business Banking, Commercial Banking, Wealth Management,
and Capital Markets. We expect to update our segment reporting in accordance with the new structure in the fourth quarter of 2026 upon
completion of supporting changes in our internal management reporting processes, and to provide a restated Supplementary Financial Information
package reflecting the new reporting structure prior to the issuance of the bank's Q4 results on December 3, 2026.
Infrastructure Groups
These changes align teams against key priorities,
and enable strong execution of the bank's client-focused strategy.
- Christina Kramer, Senior Executive Vice-President and Chief
Administrative Officer (CAO), will transition to the role of Special Advisor and leave the bank on October 31. Christina dedicated her
40-year career to our bank, making significant contributions in leadership roles across Human Resources, Personal and Business Banking,
Technology, Operations, and most recently as CAO.
"Across both business and infrastructure leadership roles, Christina has consistently put our clients at the centre of our efforts,
and has led key teams across our bank with a collaborative approach to executing on our strategy," said Mr. Culham. "In
each of her leadership roles, she has set a high standard for operating with excellence and reflecting our purpose-led, genuinely caring
culture. We are a stronger bank today thanks to her contributions."
- Amy South has been appointed Senior Executive Vice-President,
CAO and Chief of Staff, and will maintain oversight of CIBC Mellon. She will have accountability for Business Enablement and Governance;
Brand, Community, Client Experience; Communications; Corporate Security; Enterprise Real Estate; Infrastructure and Modernization; Procurement
and Enterprise Projects, and Global Government Relations.
"Amy brings deep experience across client-facing, CAO and Finance roles at our bank," said Mr. Culham. "Her breadth of
experience and enterprise perspective will be invaluable as she and her team help to accelerate the execution of our strategy."

current roles and take on additional accountabilities:

Technology and Information Officer, Global Technology, Data and AI, will add responsibility for the Chief Security Office.
