Insights

Equity analyst

Large venture holder reports sizable open‑market sales and a reduced 1.7% position.

Affiliates of New Enterprise Associates, through Growth Equity Opportunities 18 VGE, LLC and related entities, disclosed that GEO sold 17,093,034 Gossamer Bio shares in open‑market transactions on February 23, 2026. The weighted average sale price was $0.3906 per share, with a broad intraday range.

Following these sales, the group reports beneficial ownership of 4,065,134 shares, including 3,065,134 underlying GEO warrants, representing 1.7% of the company’s common stock based on 234,521,381 shares.
