Dierker Richard A

Routine dominates Richard A. Dierker's record: the Church & Dwight CFO's Form 4 history is entirely concentrated in one company — 337 transactions since 2016, with 20,950 shares bought against 636,677 sold, a lifetime pattern consistent with a long-tenured executive whose sales substantially outweigh routine compensation-linked buys. What stands out is a single transaction coded "P" — a genuine open-market purchase, not a grant or vesting event — of 5,470 shares on August 12, 2025 at $91.57 per share, worth roughly $501,000. That's a meaningfully different signal than the routine, recurring small "A" acquisitions of roughly 40-46 shares that appear almost every two weeks in this data (consistent with an ongoing stock purchase or dividend-reinvestment-style plan), or the larger periodic awards like the 2,690-share grant on January 27, 2026 and the 1,038-share tax-withholding transaction ("F") on March 3, 2026 at $103.02.
