No open-market trades were reported. The filing shows an award of 741,545 shares from performance-based PSUs and a tax-withholding disposition of 315,307 shares, which were withheld by the company to satisfy tax obligations rather than sold into the market.

How many Core Scientific (CORZ) shares does CEO Adam Taylor hold after these transactions?

After the reported equity award and tax withholding, Adam Taylor directly holds 4,557,388 shares of Core Scientific Common Stock. This figure reflects his updated ownership position following the vesting and settlement of performance-based PSUs and associated tax-share withholding.

What are the performance-based PSUs mentioned in the Core Scientific Form 4?

The performance-based PSUs are restricted stock units granted on April 28, 2025 that vest only if specific performance criteria are met. On March 31, 2026, the Compensation Committee certified the performance level and approved settlement, resulting in 741,545 shares of Common Stock delivered.

Why were 315,307 CORZ shares withheld in the CEO’s Form 4 filing?

The 315,307 shares were withheld to cover withholding tax obligations triggered by restricted stock unit vesting. Instead of the CEO selling shares in the market, the company retained these shares at $14.96 per share to satisfy required tax liabilities associated with the equity award.

How does this Form 4 impact Core Scientific (CORZ) investors’ view of insider activity?

The Form 4 reflects routine compensation and tax settlement activity, not discretionary buying or selling. Shares were delivered from vested performance-based PSUs and a portion was withheld for taxes, so the filing primarily updates the CEO’s equity holdings rather than signaling market-driven trades.
