Grzebinski David W, President & CEO of Kirby Corporation (KEX), has demonstrated a clear selling bias in his recent insider transactions, with $14.2 million in total sales outweighing $4.7 million in purchases across 36 filings. His activity has been exclusively concentrated in KEX shares, with no trades in other companies. The most significant disposals occurred on February 24, 2026 ($4.44 million sale and $2.50 million via market trade) and November 21, 2025 ($3.16 million sale with $2.18 million in market transactions). Smaller but notable sales include a $1.54 million transaction on February 12, 2024, and a $593,040 sale on February 6, 2024.
The pattern shows Grzebinski has not made any open market purchases in recent years, with all acquisitions appearing to be through derivative transactions (code F) such as option exercises, including a $1.07 million acquisition on February 3, 2026, and a $773,658 transaction on February 3, 2025. The absence of recent buys and the continuation of sales—particularly the two multimillion-dollar disposals in early 2026—suggest a sustained reduction in his KEX holdings. While some transactions involved market sales (code S), others were automatic dispositions (code M), indicating a mix of discretionary and non-discretionary sales. The data reflects a consistent trend of decreasing equity exposure rather than accumulation.
