POON CHRISTINE A

Christine A. Poon (CIK 0001189014, 449 transactions) has a five-issuer Form 4 file where the only market-priced directional transaction in the recent record is a paired Regeneron Pharmaceuticals (REGN) option exercise and partial sale in late October 2025. On October 29–30, 2025 she exercised 9,212 shares via two M-code entries (2,712 at $520.01 and 6,500 at undisclosed price) and concurrently sold 5,500 shares in five S-code legs at prices ranging from $652.68 to $657.29 — netting a partial liquidation after exercise rather than a full disposition. Her Prudential Financial (PRU) transactions in the same period — 243 lifetime events — reduce almost entirely to 'A' plan awards totaling under 6,000 shares across multiple small 2026 dates, with one 'D' code stock dividend event at $102.58, none of which carries any directional read on PRU itself. Against a REGN lifetime aggregate of 655 buy-side versus 99,953 sell-side shares, the October 2025 exercise-with-partial-sale reads as a modest diversification step at the margin, not a repudiation of the REGN position.
