Xylem has appointed two new commercial and segment leaders to its executive team.

Hayati Yarkadas is the new senior vice president, and president, Water Infrastructure & Europe Commercial Team, while Matthew Pine has been appointed SVP and president, Applied Water Systems & Americas Commercial Team.

Yarkadas was most recently president of Performance Materials at Trinseo, based in Switzerland. Pine joins Xylem from United Technologies, where he was president of the Carrier Residential business.

“As the transformation of the water sector accelerates, world-class talent and executive leadership are essential elements of our growth platform,” said Patrick Decker, president and CEO of Xylem. “Hayati brings years of multi-billion-dollar international commercial leadership, alongside rich experience and insight in the European market. And Matthew joins us with deep channel management expertise, having delivered robust, market-centered, sustainable growth in challenging end-markets.”

Yarkadas takes over from David Flinton, who was serving in the role on an interim basis. Flinton remains SVP and chief innovation, technology and product management officer.

Pine succeeds Ken Napolitano, who is retiring after working for Xylem for four decades.

“Ken started as an intern and grew with the company for forty years, delivering inestimable value to Xylem, our customers and our shareholders over that time,” said Decker. “The board and I, all Ken’s executive peers, and a generation of Xylem colleagues are deeply grateful for Ken’s principled leadership.”
