Insights

Equity ownership and governance analyst

Major shareholder reports sizeable sales but remains a 25.4% holder.

Column Group–related entities disclose updated positions in Tenaya Therapeutics. TCG III LP and TCG III-A LP sold blocks of stock on February 10–11, 2026 at weighted-average prices of $0.8161 and $0.6808 per share, for several million shares in total.

After these transactions, Tim Kutzkey and Peter Svennilson each report beneficial ownership of 54,313,559 shares, or 25.4% of Tenaya’s common stock, based on 213,744,535 shares outstanding as of December 15, 2025. A separate Column Group opportunity fund holds 49,313,559 shares, or 23.1%.

The filing also highlights warrants to purchase 53,571,426 additional shares held by a Column Group opportunity fund that are currently blocked by Beneficial Ownership Limitations and therefore excluded from beneficial ownership. Future portfolio decisions by these funds will appear in subsequent ownership updates rather than being outlined here.
