Change of governance effective July 1, 2025


Guillemot Corporation S.A., a leading player in the gaming accessories and digital audio space, is
today announcing a significant change in its governance arrangements.

The company is notifying its shareholders that the Board of Directors, at its meeting of June 5, 2025,
decided to separate the roles of Chairman of the Board of Directors and Chief Executive Officer.

At that same meeting, the Board of Directors agreed that Claude Guillemot should continue to serve
as Chairman of the Board of Directors and voted to appoint Valentin Guillemot as Chief Executive
Officer with effect from July 1, 2025.

Claude Guillemot has grown the company thanks to his ambitious strategic and financial goals. His
flair for innovation enabled the business to establish itself in the market while remaining true to its
values. As Chairman of the Board of Directors, he will continue to guide the company’s overall
direction, working closely with senior management.

Valentin Guillemot, who since joining the Group has steadily taken on more responsibility, will be
able to realize his full potential as Chief Executive Officer.

Having joined the Group in 2022, Valentin Guillemot gradually took charge of operations of the
Canadian subsidiary Guillemot Inc., becoming its Vice President in 2024.

From its earliest days, the company has always been guided by strong values: innovation, passion,
quality and an openness to users’ needs. Even now, these principles remain at the heart of the
company’s commitments.

About Claude Guillemot

Claude Guillemot has a master’s degree in economics from Université de Rennes 1 and a university

In 1984, together with his four brothers, he founded the Guillemot Corporation Group in Carentoir,

would go on to become a major player in downloadable video games for smartphones.

As well as Chairman and Chief Executive Officer of Guillemot Corporation, Claude Guillemot is also

His experience has given him a 360-degree view of the product life cycle and corporate strategy. His
new position will enable him to fully harness his ambition and innovative thinking to drive the Group’s
performance.
