Grzebinski David W

Grzebinski David W, President and CEO of Kirby Corporation (KEX), has filed 36 Form 4 transactions over the past two years, all in the single industrial services company. The pattern is unambiguous: zero open-market purchases, zero acquisitions, and roughly $9.7 million in total sales. The selling bias is consistent across the reporting window, with the most recent cluster of four transactions in February 2026 reinforcing the trend. The largest single disposal came on February 24, 2026, when Grzebinski sold KEX shares worth $4.44 million, paired with an option exercise valued at $2.50 million on the same day—a classic exercise-and-sell structure. That followed a November 21, 2025 sale of $3.16 million alongside a $2.18 million option exercise. Earlier transactions show smaller but steady monetization: $1.54 million on February 12, 2024, and $593,040 on February 6, 2024. Interspersed are numerous zero-value option exercises (code M) and tax-withholding sales (code F), such as $1.07 million on February 3, 2026, and $417,503 on January 24, 2026, which are mechanical rather than discretionary. The data reveals a CEO who regularly converts vested equity into cash, but never adds to his position through open-market buys. The February 2026 sale, at $4.44 million, is the largest single transaction in the dataset, suggesting an acceleration in the pace of monetization. While the exercise-and-sell pattern is typical for executives managing concentrated stock positions, the complete absence of any purchase activity—even at lower price points in 2024—indicates a sustained one-way flow of shares out of Grzebinski's hands.
