Rocket Pharmaceuticals to Join Russell 3000® and 2000® Indexes

Russell US Indexes are widely used by investment managers and institutional investors as the basis for index funds and as benchmarks for active investment strategies. Approximately $9 trillion in assets are benchmarked against Russell US Indexes. Russell US Indexes are part of FTSE Russell, a leading global index provider. Rocket’s addition to these indexes will increase the Company’s already growing visibility and presence with institutional investors and greater financial community.

Annual Russell US Indexes reconstitution captures the 4,000 largest US stocks as of May 11, ranking them by total market capitalization. Membership in the 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 US Indexes primarily by objective, market-capitalization rankings and style attributes.

For more information on the Russell 3000^® Index and the Russell US Indexes reconstitution, go to the “Russell Reconstitution” section on the FTSE Russell website.
