News Releases

MONMOUTH JUNCTION, N.J., June 28, 2011 /PRNewswire/ -- Insmed Incorporated (Nasdaq CM: INSM), a biopharmaceutical company, today announced that it has been added to the Russell 3000® Index following Russell Investments' reconstitution of its comprehensive set of U.S. and global equity indexes on June 24, 2011.  Membership in the Russell 3000, which remains in place for one year, means Insmed is automatically included in the small-cap Russell 2000® Index, as well as the appropriate growth and value style indexes.  Insmed was also added to the Russell Global® and Russell Microcap® Indexes.

Annual reconstitution of Russell's U.S. indexes captures and ranks the 4,000 largest U.S. stocks by total market capitalization as of the end of May.  Russell determines membership for its equity indexes primarily by objective, market capitalization rankings and style attributes.

"We believe this accomplishment is a strong indicator that the Insmed story is beginning to gain traction with institutional investors," said Timothy Whitten, Insmed's President and CEO.  "As we are preparing to begin the phase 3 program for ARIKACE® in cystic fibrosis patients who have Pseudomonas lung infections and patients with non-TB mycobacteria (NTM) lung infections in the second half of this year, we expect the addition of Insmed to the Russell 3000 Index will increase our visibility among investors, provide an opportunity to broaden our shareholder base and, ultimately, advance our efforts to enhance shareholder value."

The Russell 3000 also serves as the U.S. component to the Russell Global Index.  Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies.  An industry-leading $3.9 trillion in institutional assets currently are benchmarked to them.  These investment tools originated from Russell's multi-manager investment business in the early 1980s when the company saw the need for a more objective, market-driven set of benchmarks in order to evaluate outside investment managers.
