Eikon Therapeutics to Join the Russell 3000® Index

Addition reflects Eikon’s progress as a publicly traded company and increasing visibility within the investment community

MILLBRAE, Calif., June 25, 2026 (GLOBE NEWSWIRE) — Eikon Therapeutics, Inc. (Nasdaq: EIKN) (“Eikon”), a late-stage clinical biopharmaceutical company dedicated to developing innovative medicines to address serious unmet medical needs, today announced that it will be added to the broad-market Russell 3000^® Index following the annual reconstitution, effective after the US market closes on June 26, 2026.

The Russell US Indexes, from mega cap to microcap, serve as leading benchmarks for institutional investors. The modular index construction allows investors to track current and historical market performance by specific market segment or investment style (growth/value/defensive/dynamic). The Russell 3000 Index measures the performance of approximately 3,000 stocks, designed to represent 98% of the investable US equity market, and includes large-cap, mid-cap and small-cap US equities. Like all Russell Indexes, the Russell 3000 is fully reconstituted each year in June (and will be subject to semi-annual reconstitution beginning in December 2026) to ensure accurate reflection of the targeted market segment.
