The filing reports open market sales of **Codexis (CDXS)** common stock by entities affiliated with a **Director**. Across 11/07/2025, 11/10/2025, and 11/11/2025, Opaleye, L.P. sold 296,682, 205,000, and 535,000 shares, respectively, and a managed account sold 10,000, 3,318, and 13,211 shares.

Post-transaction, the filing shows indirect beneficial ownership of 11,508,318 shares via Opaleye, L.P. and 223,461 shares via the managed account. Ownership is reported as indirect, with customary disclaimers of beneficial ownership except to the extent of pecuniary interest. The form is filed by one reporting person and indicates the relationship as Director; it does not mark 10% owner.

The key takeaway is a sizable net reduction by a Director-affiliated holder over three trading days at approximately $1.68–$1.81. Items to watch: any subsequent Form 4s indicating continued selling, updates to beneficial ownership amounts, and whether future filings disclose plan-based trading. The next relevant checkpoint is any new transactions filed after 11/11/2025.
