Aon has appointed Karl Hamann as chief executive officer of its Philippines business, effective 1 April, subject to regulatory approval, the firm announced on Tuesday.

Hamann first joined Aon in 2022 as chief executive of Indonesia. The incoming CEO will relocate to Manila and continue to report to Andrew Minnitt, Aon’s head of Southeast Asia. He succeeds Darren Oliver, who will move into a newly created role as head of market development for APAC Health Solutions, based in Singapore.

“Karl brings a rare combination of on-the-ground experience, commercial discipline and an ability to lead with clarity through change,” Minnitt said. “His familiarity with the Philippines market and his track record across the region make him exceptionally well placed to guide the business forward.”

Hamann said he would focus on building on the existing platform established by the local team. “The Philippines has been an important part of my professional journey, and I’m excited to re-engage with the market in this new capacity,” Hamann said.

Prior to his time at Aon, Hamann held chief executive roles across Asia-Pacific markets, including QBE Insurance in Malaysia and Singapore.

The appointment comes amid a broader series of leadership changes at Aon in the Asia-Pacific region. This includes Alexander Krasavin’s recent promotion to Asia-Pacific Regional Managing Director, where he will lead integration of human capital solutions for multinational clients across the region, and Alistair Clarke’s move from the UK to Australia to take up a specialty leadership role in that market.
