Kari Hämäläinen joins with a strong track record of building growth in global technology and industrial companies — scaling operations across markets, leading strategic entries into new regions, and driving long-term revenue expansion through organic growth and acquisitions.

His appointment directly supports Temet's strategic growth objectives as demand for integrated civil, defence and industrial protective infrastructure accelerates globally.

Juha Simola will continue in a new capacity until Q4 2026, providing support to the CEO in strategic market expansion and associated priorities.

"We are at an inflection point. Governments and organisations that carry the duty to protect their people need a partner who can deliver to a standard of protective infrastructure that holds under all conditions. That is what Temet has defined and delivered since 1953. My focus is on building on what seventy years of standard-setting has created, and taking this organisation to the global scale its expertise deserves," said Kari Hämäläinen.

"Temet is growing faster than at any point in our recent history, and the global environment is creating demand that requires both operational scale and leadership of the highest calibre. Kari brings the international experience and strategic clarity to lead this organisation through an ambitious and important next chapter," said Harri Väistö, Chairman of the Board.
