A potential Infineum sale carries an indicative valuation near $8 billion, a development that could change ownership of the U.K. additives producer jointly held by Shell and ExxonMobil.
Bank of America has an advisory role in the process. Private-equity firms may be interested, though no buyer has been named. The parties have not agreed on a purchase price, and a transaction is not assured.
Infineum's products serve fuel and lubricant markets. Infineum products are sold in more than 90 countries; the joint venture was formed in January 1999.
