RESTON, Va., May 27, 2025 (GLOBE NEWSWIRE) -- Lightbridge Corporation (“Lightbridge” or the “Company”) (Nasdaq: LTBR), an advanced nuclear fuel technology company, has been added as a member of the broad-market Russell 3000® Index and the small-cap Russell 2000® Index, effective after the US market opens on June 30, as part of the 2025 Russell indexes reconstitution.

The annual reconstitution of the Russell US indexes captures the 4,000 largest US stocks as of April 30, 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 and the appropriate growth and value style indexes. FTSE Russell determines membership for its Russell indexes primarily by objective, market-capitalization rankings, and style attributes.

Seth Grae, President & Chief Executive Officer of Lightbridge Corporation, commented, "Being added to the Russell 2000® Index and Russell 3000® Index represents an important milestone for Lightbridge and reflects our growing market presence as we advance our transformative nuclear fuel technology. This inclusion validates our progress and enhances our visibility among institutional investors at a pivotal time for nuclear energy. As we continue executing our mission to deliver more power and optimize nuclear fuel performance and safety, we are pleased to have achieved this recognition that comes with expanded access to capital markets and increased liquidity for our shareholders."

Investment managers and institutional investors widely use Russell indexes for index funds and as benchmarks for active investment strategies. According to data as of the end of June 2024, about $10.6 trillion in assets are benchmarked against the Russell US indexes, which belong to FTSE Russell, the global index provider.

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 the indexes maintain an accurate representation of the market. The transition to a semi-annual reconstitution frequency from 2026 will ensure our indexes continue to represent the market and maintain the purpose of the index as a portfolio benchmark.”
