Confidence rating:

The majority of Wang's fortune is derived from his control of Amer International Group, the closely held copper miner and processor he founded in 1994. The company is 90% owned by Wang and 10% by a sibling about whom little is known. 

Amer had revenue of about $112 billion and stockholder equity of $19.6 billion in 2021, according to a Fortune Global 500 ranking. The base valuation is calculated based on the reported equity value and this is adjusted to reflect changes in the BI Global Copper Competitive Peer Group index.

Wang also owns a 27% stake of publicly-traded Jiangsu Jiuding, according to a Dec. 7, 2022 filing. About one-quarter of his stake is pledged and removed from the calculation. He acquired the stake in November 2019, according to a company disclosure.

The billionaire also owns property assets through Singapore-based investment company, Wen Way. These are valued at their 2013 purchase price in 2013, according to its website. The costs of Wen Way's land acquisitions and industrial parks construction in China are included as liabilities.

Fan Xinlan, a spokesperson for Amer, declined to comment on the billionaire's net worth.

Wang Wenyin was born in Anqing, a city in the Chinese province of Anhui, on March 2, 1968, according to filings with the UK's Companies House.
