Mobix Labs Added to Russell® Microcap Index and Russell 3000E Index Growth Benchmark
Mobix Labs, Inc. (NASDAQ:MOBX) announced it has been added to the Russell Microcap® Index, effective with the market’s opening on June 29, as part of the 2026 Russell indexes reconstitution. Through its addition to the Microcap Index, Mobix Labs is also included in the Russell 3000E® Index, which provides the broadest coverage of investable US equities.
Russell Indexes Attract Significant Investment
Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies. Approximately $12 trillion in assets are currently benchmarked to or invested in products tracking Russell U.S. indexes.
Russell Microcap® Index
Membership in the Russell Microcap® Index remains in place for half a year and means automatic inclusion in the appropriate growth and value style indexes. FTSE Russell determines membership for its indexes primarily by objective, market-capitalization rankings and style attributes. As of April 30, 2026, the Russell Microcap® Index included 1,375 securities with market caps ranging from $1.1B to $30.1M.
Russell 3000E® Index
The Russell 3000E® Index is an ultra-broad market benchmark that tracks the performance of the largest publicly traded U.S. companies. It combines the Russell 3000® Index with the Russell Microcap® Index to provide the broadest coverage of investable US equities, including up to the 4,000 largest US stocks by total market capitalization as of the reconstitution rank date. Mobix Labs has been included in the Russell 3000E Growth Benchmark, a growth-oriented segment of the Russell 3000E® Index.
Mobix President and CFO, Keyvan Samini, commented, "We are pleased to be included in the Russell Microcap and 3000E Indexes. We believe our membership could be helpful in expanding Mobix Labs’ exposure to institutional investors and the broader investment community, in addition to index funds and ETFs that utilize Russell indexes to manage a substantial pool of global assets."
Fiona Bassett, CEO of FTSE Russell, an LSEG business, commented, "The Russell indexes have continuously adapted to the evolving dynamic US economy, and it’s crucial to fully recalibrate the suite of Russell US Indexes, ensuring they maintain an accurate representation of the market. The transition to a semi-annual reconstitution frequency this year will ensure our indexes continue to represent the market and maintain the purpose of the index as a portfolio benchmark."
