Yeoh family
Yeoh Tiong Lay, from a family of Chinese immigrants from Kinmen, founded a small construction firm in 1955 at age 25 during Malaysia's post-independence infrastructure push. The firm survived the 1970s oil-crisis shocks and was incorporated as Yeoh Tiong Lay Sdn Bhd in 1972, going public and restructuring as YTL Corporation by 1985.
How the fortune was built
YTL diversified into power generation, cement, property, hospitality, and telecommunications, and in 1996 became the first non-Japanese Asian company listed on the Tokyo Stock Exchange. Its most significant move came in 2002, winning a competitive bid against roughly two dozen rivals to acquire UK utility Wessex Water for £1.2 billion, giving YTL a stable, regulated cash-flow asset and transforming it into a cross-border infrastructure group, now led by Francis Yeoh.
Where the family invests today
The group's most notable recent pivot is AI infrastructure: Nvidia and YTL announced a roughly $4.3 billion plan to build AI data-center capacity in Johor, Malaysia, with over $2 billion already spent on 200-plus megawatts of operational capacity. YTL Power has also earmarked around $2.4 billion for AI infrastructure and services, including Malaysia's first large language model. Wessex Water separately plans an estimated £3.5 billion in UK infrastructure investment over the next five years.
