SINGAPORE -- Singapore-based agricultural commodities trader Olam International will acquire a U.S. manufacturer of spices and seasonings for $950 million, the company said Thursday, as it hopes to capture growing demand there by creating an end-to-end supply chain. Olam will buy all the shares of California-headquartered Olde Thompson by the end of June. Olde Thompson is currently 75% owned by Kainos Capital, a U.S. private equity fund, and the rest by the founding family. Spices are among Olam's key trading products, including rice, cacao, coffee and cotton.
