Oklo (OKLO) CTO Patrick Schweiger Receives RSUs, Sells Shares for Taxes

What Happened

Patrick Schweiger, Chief Technology Officer of Oklo Inc. (OKLO), had 2,884 restricted stock units (RSUs) release/vest on March 6, 2026. Of those, 1,280 shares were surrendered to cover tax withholding at $58.26 per share, totaling $74,573. The net shares delivered to Schweiger from this vesting were 1,604 shares.
The filing also reports RSU grants dated December 22, 2025 (see footnotes), including a 27,500‑RSU award and an 8,652‑RSU award with various vesting schedules; those are awards (not open‑market buys or sales).

Key Details

Transaction dates: RSU vest/conversion and tax withholding occurred on 2026-03-06; grants were dated 2025-12-22 (reported in this filing).
Prices/values: Tax withholding resulted from surrender of 1,280 shares at $58.26/share = $74,573. The RSU grants are $0 exercise price (they are awards).
Net shares received from the March 6 vesting: 1,604 shares (2,884 vested − 1,280 withheld).
Shares owned after the transactions: not specified in the excerpt of the filing.
Footnotes: F1 confirms 2,884 RSUs were released on March 6, 2026; F2/F4 describe separate RSU grants dated December 22, 2025 with multi‑year vesting schedules; F3 reiterates that each RSU converts to one share.
Timeliness: The March 6, 2026 vesting/tax withholding was reported on Form 4 filed March 10, 2026 (appears within the normal 2‑business‑day window). The December 22, 2025 grants, however, were reported later (filed March 10, 2026) and thus the grant reporting is delayed.

Context

These entries are RSU vesting and tax‑withholding transactions (derivative conversion and share surrender for taxes), not open‑market purchases or sales for investment. RSUs convert into shares when they vest; it is common for companies to withhold a portion of vested shares to satisfy tax obligations.
Awards/grants and routine tax withholding generally do not by themselves indicate buying or selling sentiment by the insider.
