Drinks heavyweight Diageo has announced a US$500 million cost savings program over the next three years as the company braces for trade tariffs. The cost-cutting will enable the company to reinvest in future growth and improved operating leverage. The British multinational, which owns brands such as Guinness, Johnnie Walker, and Smirnoff, has estimated that the impact of US tariffs, in their current form, will be around US$150 million annually.
