Biguet Stephane, EVP & CFO at SLB (formerly Schlumberger), has demonstrated a consistent pattern of selling activity in the company’s stock, with no recorded purchases across 27 reported transactions. Since 2024, Biguet has executed multiple sales totaling over $13.6 million, with the most recent transactions occurring in early 2026. Notably, on January 26, 2026, Biguet sold shares worth approximately $3.03 million, following a $1.03 million sale on January 23, 2026, and a $297,254 transaction on January 18, 2026. These disposals align with earlier sales in November 2025 ($1.41 million) and January 2025 ($1.97 million), reinforcing a multi-year trend of reducing holdings.
The filings also show derivative transactions, primarily involving the exercise of options (coded "F") and awards (coded "A"), though these did not result in additional equity acquisitions. For instance, on March 13, 2026, a $60,979 derivative transaction was reported alongside a $0 award, mirroring similar activity in prior years. Biguet’s sales have been concentrated in January and March, suggesting potential alignment with corporate vesting schedules or trading windows. With no buys and repeated sales—including a $3.04 million disposal in February 2024 and a $329,875 sale in January 2024—the data reflects a clear divestment strategy in SLB shares over the observed period.
