DUCHENE TODD M 4

What Happened
Todd M. Duchene, Core Scientific's Chief Legal and Administrative Officer, reported multiple dispositions at the end of June 2026. On 2026-06-29 he sold 8,800 shares at a reported weighted-average price of $25.99 (proceeds $228,701), 1,100 shares at $27.42 (proceeds $30,162) and 100 shares at $27.95 (proceeds $2,795) — total open-market sales of 10,000 shares for about $261,658. On 2026-06-30 there was a disposition of 5,469 shares reported as payment for tax withholding upon RSU vesting at $25.59 (value $139,952). Combined, the transactions are reported at roughly $401,610. The sales were executed under a pre-arranged Rule 10b5-1 trading plan and the tax-withholding reflects RSU vesting rather than an open-market sale.

Key Details

• Transaction dates: 2026-06-29 (open-market sales) and 2026-06-30 (tax withholding on RSU vesting).
• Prices and proceeds: 8,800 @ $25.99 = $228,701; 1,100 @ $27.42 = $30,162; 100 @ $27.95 = $2,795; 5,469 @ $25.59 = $139,952. Total ≈ $401,610.
• Footnotes: Trades were executed under a Rule 10b5-1 plan adopted 2025-12-05 (F1). Reported sale prices are weighted averages; per-footnote ranges are provided for the sales (F2/F3) and the filer will provide per-price breakdowns on request. F4 notes shares were withheld to satisfy tax withholding on RSU vesting.
• Shares owned after transaction: not specified in the excerpt provided.
• Filing timeliness: Form 4 was filed 2026-07-01 for transactions on 6/29–6/30; this appears to be within the standard Form 4 reporting window (generally two business days).

Context and plain-language notes: Sales made under a Rule 10b5-1 plan are pre-arranged trading programs and are often routine; the 5,469-share disposition was a withholding to cover taxes on vested restricted stock units (not an open-market sale). For most retail investors, purchases tend to be more informative about insider conviction; these reported sales and tax-withholding are consistent with routine compensation and pre-planned selling.
