SES Set to Join Russell 3000® Index

BOSTON--(BUSINESS WIRE)-- SES AI Corporation (NYSE: SES), headquartered in Boston, a global leader in the development and manufacturing of high-performance lithium-metal (Li-Metal) rechargeable batteries for electric vehicles (EVs) and other applications, today announced it is set to join the broad-market Russell 3000^® Index. SES will be added at the conclusion of the 2023 Russell indexes annual reconstitution, effective after the US market opens on June 26, according to a preliminary list of additions posted by FTSE Russell May 19.

The annual Russell reconstitution captures the 4,000 largest US stocks as of April 28, 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.
