LightPath Technologies Joins Russell 3000® Index

Inclusion Reflects LightPath's Significant Growth and Expanding Role in Defense and Commercial Optics

ORLANDO, Fla., June 29, 2026 /PRNewswire/ -- LightPath Technologies, Inc. (NASDAQ: LPTH) ("LightPath," the "Company," or "we"), a leading provider of next-generation optics and imaging systems for both defense and commercial applications, today announced that it has joined the small-cap Russell 2000^® Index and the broad-market Russell 3000^® Index, effective with the opening of US equity markets today, Monday, June 29, 2026, marking the conclusion of the 2026 Russell indexes reconstitution.

The June reconstitution of the Russell US Indexes captures up to the 4,000 largest US stocks as of April 30, 2026, ranking them by total market capitalization. LightPath's membership in the Russell 3000^® Index, which remains in place for half a year beginning 2026, means automatic inclusion in the small-cap Russell 2000^® Index, as well as the appropriate growth and value style indexes. FTSE Russell determines membership for its Russell indexes primarily by objective market-capitalization rankings and style attributes.

Sam Rubin, President and Chief Executive Officer of LightPath, commented: "We are pleased to join the Russell 2000 and 3000 indices, a milestone that reflects the significant growth in our business and market capitalization over the past year as we scaled our business into a leading IR optics provider to the United States and its allies. We believe our inclusion in these widely followed indices will enhance LightPath's visibility within the institutional investment community, expand our shareholder base and improve trading liquidity as we continue executing on our strategy to build a vertically integrated leader in next-generation optical solutions."

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies. According to data as of the end of June 2025, approximately $12.2 trillion in assets are benchmarked against the Russell US indexes, which belong to FTSE Russell, the global index provider.
