SLB's General Counsel Sold $1.1 Million in Stock With No Preset Plan
As seen on the 24/7 Wall St. homepage on October 30, 2026.
SLB's legal chief trimmed about 10% of her stake at $53.57 a share, with no 10b5-1 plan disclosed on the filing. She still holds roughly 205,000 shares, so this reads as a sizable discretionary trim, and it lands while the offshore and digital growth story is doing the heavy lifting for the stock.

Dianne B. Ralston, SLB's chief legal officer, sold shares on October 30 for just over $1.1 million in proceeds. The filing disclosed no 10b5-1 plan, so this was not a pre-scheduled, rules-based transaction set up in advance.
Sales made outside a 10b5-1 plan are discretionary: the seller chose the timing and price without a pre-arranged schedule. A trim of roughly 10% of a senior executive's stake on that basis tends to get attention.

Ralston still holds approximately 205,000 shares after the transaction, so she retains a substantial personal stake in the company's performance. The size of her remaining position means her financial interests remain closely tied to where the stock goes from here.
The sale lands while SLB's offshore drilling and digital growth segments have been carrying much of the weight for the stock's investment thesis. The filing states no reason for the transaction, and the facts do not support reading further into it than what the document shows.
