HOLLISTON, Mass. — Harvard Bioscience, Inc. (Nasdaq:HBIO), a global developer, manufacturer and marketer of a broad range of solutions to advance life science, is set to simultaneously join two broad-market Russell indexes. According to Russell’s preliminary list of additions, the Company is expected to be added to the Russell 3000® Index and the Russell Global Index at the conclusion of the annual Russell indexes reconstitution on June 26, 2015.

Jeffrey A. Duchemin, President and Chief Executive Officer of Harvard Bioscience, said, “We believe inclusion in the Russell 3000 and Russell Global indexes will increase our recognition in the global financial community, much as our global commercial activities have enhanced our market position in the life sciences industry.”

Annual Russell indexes reconstitution captures the 4,000 largest U.S. stocks as of the end of May, 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. Membership in the Russell Global index, which also remains in place for one year, means automatic inclusion in the appropriate large-cap, small-cap, all-cap indexes as well as the applicable style, sector and country 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 $5.7 trillion in assets are benchmarked to the Russell’s U.S. indexes. Russell indexes are part of FTSE Russell, a leading global index provider.
