American Express Global Business Travel Expected to Join the Russell 2000® and 3000® Indexes

American Express Global Business Travel, which is operated by Global Business Travel Group, Inc. (NYSE: GBTG) (“Amex GBT” or the “Company”), the world’s leading B2B travel platform, today announced it is expected to join the Russell 2000^® and 3000^® Indexes on June 23, 2023, after the market closes, according to a preliminary list of additions posted by the FTSE Russell on May 19, 2023.

Annual Russell indexes reconstitution captures the 4,000 largest US stocks as of April 28, 2023, ranking them by total market capitalization. Membership in the US all-cap Russell 3000^® Index, which remains in place for one year, means automatic inclusion in the large-cap Russell 1000^® Index or small-cap Russell 2000^® Index as well as the appropriate growth and value style indexes. FTSE Russell determines membership for its Russell indexes primarily by objective, market-capitalization rankings and style attributes.

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies. Approximately $12.1 trillion in assets are benchmarked against Russell’s US indexes. Russell indexes are part of FTSE Russell, a leading global index provider.

The information contained in the press release regarding FTSE Russell and the Russell indexes was supplied by FTSE Russell. For more information on the Russell 3000^® Index and the Russell indexes reconstitution, go to the “Russell Reconstitution” section on the FTSE Russell website.
