Kirby CEO David Grzebinski Sells $2.59 Million of Stock
Kirby CEO David Grzebinski sold 18,310 shares of the marine transportation company for $2,587,569, according to a Form 4 filed Wednesday.
The sale took place Nov. 2, 2026, at a weighted average price of $141.32 per share, with individual prices ranging from $140.12 to $143.05, the filing shows. Grzebinski is Kirby's chief executive and a member of its board.
The filing reports an open-market sale only. It does not show an option exercise or other transaction alongside it, and it does not indicate that the trade was made under a prearranged Rule 10b5-1 trading plan.
What he still holds
After the sale, Grzebinski directly held 79,931 Kirby shares, according to the filing. The shares he sold represented 18.6% of his direct holdings before the trade.
Why it matters
Sales by a sitting CEO draw attention from investors because top executives have the closest view of a company's business. Executives sell stock for many reasons, including diversification, taxes and personal financial planning, and a single sale does not necessarily signal a view on the shares. Grzebinski kept more than four-fifths of his direct stake after the trade.
The trade came less than a week after Houston-based Kirby reported its third-quarter results in late October.
