PESI PermaFix Environmental Services Inc

Perma-Fix Environmental Services, Inc. (NASDAQ: PESI) (the “Company”) announces it has been added as a member of the Russell 3000 Index, effective after the US market opens today, July 1, as part of the 2024 Russell indexes reconstitution.

The annual reconstitution of the Russell US indexes captures the 4,000 largest US stocks as of April 30, ranking them by total market capitalization. Membership in the Russell 3000® Index, which remains in place for one year, means Perma-Fix’s automatic inclusion in the 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.

Mark Duff, President and CEO of Perma-Fix, commented, “We are honored to report Perma-Fix's inclusion in the Russell 3000 Index, which underscores our commitment to solving some of the nation’s and the world’s most pressing environmental challenges. We believe this milestone reflects the dedication of our team and the progress of our strategic initiatives.”

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies. According to data as of the end of December 2023, about $10.5 trillion in assets are benchmarked against the Russell US indexes, which belong to FTSE Russell, a prominent global index provider.

Fiona Bassett, CEO of FTSE Russell, an LSEG Business, comments: “Russell indexes–now in their 40th year–continue to evolve to reflect the dynamic US economy. Annual rebalancing plays a vital role in establishing accurate benchmarks, ensuring they correctly mirror their designated market segments and remain unbiased in terms of size and style.”
