How many Steel Dynamics (STLD) shares were granted to Richard Poinsatte?

Richard Poinsatte was granted 6,253 shares of Steel Dynamics common stock. The award was issued under the company’s 2023 Equity Incentive Plan and approved by the Compensation Committee, representing stock-based compensation rather than an open-market purchase transaction by the executive.

Why were 2,744 STLD shares withheld in Poinsatte’s Form 4?

The 2,744 Steel Dynamics shares were withheld to pay Poinsatte’s tax liability on his equity award. The company retained these shares, as allowed under its plan terms and Compensation Committee approvals, instead of Poinsatte selling shares in the open market to cover those taxes.

Did Richard Poinsatte buy or sell STLD shares on the open market?

The filing shows no open-market buys or sells by Richard Poinsatte. He received 6,253 shares as an equity grant, and 2,744 shares were withheld by the issuer for tax purposes, which is a non-market disposition back to the company, not an exchange-traded sale.

How many Steel Dynamics shares does Poinsatte own after these transactions?

After the grant and tax withholding, Richard Poinsatte directly holds 30,918 Steel Dynamics common shares. This figure reflects his updated ownership position following receipt of 6,253 awarded shares and the withholding of 2,744 shares returned to the issuer for tax obligations.

What is the significance of codes A and F in this STLD Form 4?

Code A indicates an acquisition as a grant or award of stock to Poinsatte. Code F reflects shares withheld by the issuer to pay taxes tied to that grant, meaning the disposition is to the company for tax purposes rather than a discretionary market sale.
