Ralston Dianne B. 4

What Happened

• Dianne B. Ralston, Chief Legal Officer and Secretary of SLB (SLB), received a grant of 23,987 restricted stock units (RSUs) on January 21, 2026. The award is reported as an acquisition (transaction code A) and no dollar price or immediate cash value was reported in the Form 4.

Key Details

• Transaction date: January 21, 2026 (reported on Form 4 filed January 23, 2026). The filing appears to meet the typical two-business-day Form 4 deadline.
• Securities granted: 23,987 restricted stock units (RSUs); price reported as N/A (award, not an open-market trade).
• Vesting: 100% of the RSUs vest on January 21, 2029 (see footnote).
• Footnotes: F1 — each RSU equals the right to receive one share at settlement; F2 — award granted Jan 21, 2026 and vests fully Jan 21, 2029.
• Shares owned after transaction: not specified in the filing.

Context

• RSU awards are a form of compensation, not an immediate market purchase or sale. These units convert into actual shares only when they vest (here, in three years), and do not necessarily indicate near-term buying or selling by the insider.
