Luc Themelin, CEO of Mersen

Message from the CEO

Sustainable growth

“There are many different ways to develop a group, from driving up volumes to broadly diversifying product lines or frantically acquiring assets.

Mersen defined its road map several years ago and chose a path of sustainable, profitable growth.

Today, our strong and controlled development is proof of Mersen’s commitment to corporate social responsibility from day one, of a commitment we have continued to honor over the years and that is now shared by all our employees.

Our CSR approach, present at every level of our business, helps us grow while remaining faithful to our values: responsible and ethical development for lasting growth.”
