What Happened
Robert J. Braithwaite Jr., SVP, Marketing & Sales of Core Natural Resources (CNR), received a grant of 4,440 restricted stock units (RSUs) on 2026-02-17 (code A). On 2026-02-18, 774 shares were withheld to satisfy tax obligations from prior RSU vesting (two withholdings: 310 shares and 464 shares) at $88.96 per share, totaling $68,855 (codes F).

Key Details

• Transaction dates: RSU grant on 2026-02-17; tax-withholding disposals on 2026-02-18. Form filed 2026-02-19 (reporting period 02-17).
• Prices/values: RSU grant reported at $0.00 (typical for awards); withheld shares sold/retained at $88.96 each — 310 shares = $27,578; 464 shares = $41,277; total ~$68,855.
• Shares reported after transactions: 16,290 total reported beneficially owned; of those, 8,169 are unvested RSUs (per filing footnote).
• Footnotes: F1 — RSUs vest annually in equal installments over three years beginning on the first anniversary of the grant. F2 — withheld shares represent tax withholding on vesting. F3 — breakdown of reported shares (see above).
• Transaction codes: A = award/grant; F = tax withholding (not an open-market sale). No indication in the filing that this was a late report.

Context
RSUs are contingent rights to receive shares upon vesting; the 4,440 RSUs will vest in scheduled installments (three-year cliff/installment per F1), so this is a compensation award rather than a market purchase. The withheld-share transactions are routine tax-withholding actions (cashless/share withholding) and do not necessarily indicate insider sentiment about the company. Purchases (P) are typically more informative about bullish conviction than awards or routine tax withholdings.
