LightPath Technologies Joins Russell 3000 and 2000 Indexes

The transition marks a significant milestone for the firm, which specializes in infrared optics and imaging systems for defense and commercial sectors. Membership in the Russell 3000 automatically secures the company a spot in the small-cap Russell 2000 index, along with various growth and value style benchmarks. FTSE Russell selects these constituents based on objective market-capitalization data and specific style attributes.

President and CEO Sam Rubin stated that the move reflects the company’s recent business expansion and its role as a provider of infrared optics to the United States and its allies. Management expects the shift to increase institutional visibility and improve trading liquidity. With approximately $12.2 trillion in assets benchmarked against the Russell US indexes as of June 2025, the indices serve as primary trackers for both active investment strategies and passive index funds.
