Pafitis Demosthenis, Chief Technology Officer at SLB (formerly Schlumberger), has demonstrated a consistent pattern of selling activity in the company’s stock over the past two years, with no recorded purchases. SEC filings reveal 25 transactions totaling $7.77 million in sales, all involving SLB shares. The largest single sale occurred on May 14, 2024, when Demosthenis disposed of shares worth $3.04 million. Other notable dispositions include a $1.59 million sale on January 19, 2024, and an $884,299 transaction on January 23, 2026. The most recent filing, dated March 13, 2026, shows a $52,577 sale, continuing the trend of periodic divestments.
The transactions are primarily coded as "F" (dispositions under Rule 16b-3), with several "A" (awards or grants) and "M" (exercises of derivative securities) filings showing no monetary value, suggesting these represent stock awards or option exercises rather than open-market purchases. The absence of buy transactions and the recurring sales—particularly the multi-million-dollar dispositions—indicate a clear reduction in Demosthenis’s SLB holdings over time. While the filings do not specify the reasons for these sales, the pattern aligns with executives periodically liquidating equity compensation. The activity remains confined to SLB, with no trades in other securities disclosed in the filings.
