NEW YORK, Aug. 26, 2026 /PRNewswire/ -- 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.

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.
