Bloomberg Indices announced the following changes to the Bloomberg 500 (B500) Index, effective prior to the open of trading on Thursday, September 10, 2026, to coincide with the September reconstitution of the index. The B500 contains 500 of the most highly capitalized US companies, weighted by float-adjusted market capitalization, representing more than USD 60 trillion in aggregate market capitalization.

Ten new firms will enter the index: Revolution Medicines Inc. (RVMD UW Equity), Flex Ltd. (FLEX UW Equity), Credo Technology Group Holding Ltd (CRDO UW Equity), Casey's General Stores Inc. (CASY UW Equity), Sunbelt Rentals Holdings Inc. (SUNB UN Equity), Carpenter Technology (CRS UN Equity), Curtiss-Wright Corp. (CW UN Equity), ATI Inc.

The additions span the Industrials, Financials, Technology, Consumer Staples, Materials and HealthCare Bloomberg Industry Classification System (BICS) sectors, in descending order of representation. The additions of Flex Ltd. and Casey's General Stores will double the representation of the Electronics Manufacturing Services/Original Design Manufacturer and Food & Drug Stores BICS sub-industries, respectively.

Thirteen firms will be removed from the index, with removals concentrated primarily in the Consumer Discretionary, Technology and Industrials BICS sectors. The removal of APIV PLC and Versigent PLC will result in the two securities currently representing the Auto Parts BICS sub-industry leaving the index.
