Cullinan Therapeutics Dropped from Multiple Russell Indices

September 21, 2025
On June 30, 2025, Cullinan Therapeutics, Inc. was dropped from several prominent Russell indices, including the Russell Microcap Growth Index, Russell 3000E Growth Index, Russell 2000 Growth Index, Russell 2500 Growth Index, Russell 3000 Growth Index, and Russell Small Cap Comp Growth Index. This removal from multiple indices is a consequence of the company's reclassification as a "smaller reporting company," which is effective December 31, 2025. Such reclassifications can impact a company's investment profile. The change in index inclusion could potentially make Cullinan Therapeutics' common stock less attractive to some institutional investors who track these indices, possibly leading to a less active trading market and increased stock price volatility.
