Ralston Dianne B.

Ralston Dianne B., Chief Legal Officer & Secretary, has demonstrated a consistent pattern of selling activity in SLB (Schlumberger Limited) shares, with no recorded purchases across 25 transactions since early 2024. SEC filings reveal $10.1 million in total sales, with recent dispositions including a $921,541 sale on January 26, 2026, and an $887,766 transaction three days prior. The transactions follow a recurring schedule, with notable sales occurring in January and March annually—such as the $1.89 million disposition on January 21, 2025, and $1.43 million sold on September 12, 2025. Smaller transactions, often coded as derivative dispositions (Code F), appear alongside these larger outright sales (Code S), including a $557,61 transaction on March 13, 2026, and multiple sub-$400,000 dispositions in prior years. The absence of buy transactions suggests Ralston has been systematically reducing exposure to SLB equity. The sales are executed at regular intervals, frequently clustered in Q1, which may align with vesting schedules or tax planning. While derivative transactions (Code F) represent smaller amounts—such as $171,859 on January 18, 2026, or $325,756 on March 1, 2024—they reinforce the overall trend of divestment. The activity remains confined to SLB, with no diversification into other securities. The pattern reflects a disciplined approach to reducing holdings rather than short-term trading, with no countervailing acquisitions to offset the sales.
