FAQ

What insider transactions did Matthew M. Dannegger report for Landstar (LSTR)?

Matthew M. Dannegger reported one stock grant and one tax-withholding transaction. He acquired 1,175 Landstar common shares on January 30, 2026, then 357 shares were withheld on January 31, 2026 to cover tax obligations, leaving him with 5,556 directly owned shares.

How many Landstar (LSTR) shares does Matthew M. Dannegger own after this Form 4?

After the reported transactions, Dannegger directly owns 5,556 Landstar shares. His holdings rose with a 1,175-share acquisition, then fell when 357 shares were withheld for tax obligations, resulting in a net reported direct ownership of 5,556 common shares.

What does the tax withholding transaction on Landstar (LSTR) shares mean?

The filing states that 357 shares were withheld to pay tax withholding obligations. This means shares were not sold as a discretionary trade, but retained by or delivered to satisfy taxes due in connection with his equity compensation, reducing his net share count.

At what price were the Landstar (LSTR) shares withheld for taxes?

The 357 Landstar shares withheld for taxes are reported at $148.91 per share. This per-share value is used in the Form 4 to reflect the transaction coded “F,” which the footnote explains relates to covering tax withholding obligations on his equity award.

Was Matthew M. Dannegger’s Landstar (LSTR) stock acquisition a purchase?

The Form 4 shows an acquisition of 1,175 shares at a price of $0. A zero-price acquisition typically reflects equity compensation, such as vested stock or awards, rather than an open-market purchase funded with cash, increasing his direct holdings before tax withholding.

Does this Landstar (LSTR) Form 4 indicate a large insider sale?

The Form 4 does not show a large discretionary insider sale. It reports 357 shares disposed of in a transaction coded “F,” which the footnote clarifies were withheld solely to satisfy tax withholding obligations, not an open-market sale initiated for portfolio reasons.
