What Happened
William Carroll Murphy, Oklo’s Chief Legal & Strategy Officer, had 5,191 restricted stock units (RSUs) released (converted to shares) on March 6, 2026. To satisfy tax withholding related to RSU settlement, 5,191 shares were withheld/disposed and on March 9, 2026 he sold 2,820 shares in the open market at $56.69 each for proceeds of $159,866. Separately, Murphy was granted 27,500 RSUs on December 22, 2025 (vesting schedule described below).

Key Details

• Filing date: March 10, 2026 (reporting period listed as 2025-12-22).
• RSU release/conversion: 5,191 RSUs released to the reporting person on March 6, 2026 (footnote F1).
• Withholding/disposition: 5,191 shares were disposed at $0 to satisfy withholding/tax obligations upon settlement (Table II derivative disposition, footnote F2).
• Open-market sale: 2,820 shares sold on March 9, 2026 at $56.69 per share, totaling $159,866 (footnote F2 states this was a "sell-to-cover" to satisfy tax withholding and not a discretionary sale).
• Grant: 27,500 RSUs granted December 22, 2025, vesting one-third on March 31, 2027 and thereafter in two substantially equal annual installments (footnote F5). Other RSU grants referenced in footnotes (F3) include smaller earlier awards.
• Shares owned after transaction: not specified in the provided excerpt of the filing.
• Notable: The sale is labeled a sell-to-cover for tax withholding (not a market-timed divestiture); RSUs are a contingent right to one share each (footnotes F1, F4).

Context

• RSUs are equity awards that convert to shares when they vest; companies commonly withhold or sell some shares to cover taxes. Such sell-to-cover transactions are routine and do not necessarily signal insider sentiment about the company.
• The filing shows conversion/settlement of RSUs and related withholding plus a market sale to cover remaining tax obligations. No discretionary purchase of stock is reported.
