DALLAS--(BUSINESS WIRE)-- Granite Ridge Resources, Inc. (“Granite Ridge” or the “Company”) (NYSE: GRNT) today announced that it is set to join the broad-market Russell 3000^® Index 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 May 19.

Annual Russell indexes reconstitution captures the 4,000 largest US stocks as of April 28, ranking them by total market capitalization.

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.
