SLB SCHLUMBERGER LIMITED/NV Insider Trading

SLB CEO sells 25,000 shares ($1.4M) on scheduled 10b5-1 plan; stock up 9.7% in 90 days.

Peuch Olivier Le, CEO of SLB LIMITED/NV, sold 25,000 shares at $56.99 on 2026-05-27, reducing holdings to 1,366,328 shares. This sale is part of a pre-arranged 10b5-1 trading plan adopted on 2025-03-25, meaning the transaction was scheduled and not discretionary. The stock has appreciated 9.7% over the past 90 days and currently trades at $56.50, only 3.9% below its 52-week high of $58.82. Across his prior four trades at SLB, the insider's 90-day post-trade returns averaged +2.7% to +14.7%, indicating a pattern of selling before continued appreciation; his broader cross-ticker track record shows 4 prior sales with an average 90-day return of +9.8%, similar to the current 90-day move. Given the scheduled nature of this sale under a 10b5-1 plan, no timing inference is warranted. The transaction represents a modest 1.8% reduction in his SLB stake while the company reports $8.7B quarterly revenue, $752.0M net income, and a $84.5B market cap.

SLB EVP Gassen sells 53,379 shares at $56.16–$56.19 for $2,998,766.01; halves holdings to 47,421 shares

Gassen Steve Matthew, EVP of Geographies at SLB, executed 2 separate sales on 2026-05-01 totaling 53,379 shares for $2,998,766.01 at prices between $56.16 and $56.19, reducing his holdings from 100,800 shares to 47,421 shares. This represents a -53.0% reduction in his pre-transaction position. The transaction occurred at prices near the 52-week high of $56.92, and follows a period of significant stock appreciation: 30-day change of +13.8% and 90-day change of +17.6%. The scale and discretionary nature of this multi-tranche sale—executed at market-peak pricing—merit investor attention, particularly given Gassen's senior role in a capital-intensive energy-services business with a P/E of 25.52 and a market cap of $85.1B.

SLB CEO Olivier Le Peuch sells $1.41M in stock near 52-week highs.

Olivier Le Peuch, SLB's Chief Executive Officer, sold a meaningful block of shares near the company's recent highs, after the stock has recovered roughly 10% over the past three months. The sale represents less than 2% of his holdings, suggesting this is portfolio rebalancing rather than panic liquidation. Against this context, the timing merits scrutiny: Le Peuch is divesting while the stock sits just below its 52-week peak and the company demonstrates solid profitability with growing revenues. This combination—a C-suite executive taking chips off the table at elevated valuations—is a common signal of conviction that current prices reflect fair or full value, though not necessarily a red flag of distress. Without visibility into Le Peuch's broader compensation strategy or vesting schedule, a single $1.4M sale from the CEO is routine corporate governance activity, but investors should monitor whether additional insiders follow suit.

CEO Le Peuch sold 25,000 SLB shares at $50.56; retains 1,416,328 shares; stock at 52-week high.

Le Peuch Olivier, CEO of SLB Limited/NV, sold 25,000 shares on 2026-03-25 at $50.56, valued at $1,264,000.00, reducing holdings by 1.7% to 1,416,328 shares. The sale occurred as the stock trades at $51.89, at the 52-week high of $51.89, following a 36.7% gain over 90 days and a 1.3% gain over 30 days. His same-ticker history shows two prior sales on 2026-02-25 and 2026-01-28, with the January sale posting a 30-day return of +1.9%; outcomes from the February sale remain unmeasurable. The CEO retains substantial equity in the firm and the company posted solid quarterly net income of $739,000,000 despite annual revenue declining 1.6% year-over-year; at a P/E of 30.35 and market cap of $77,592,750,756.65, the valuation is elevated relative to historical baseline.

SLB CEO Le Peuch Olivier sold 25,000 shares (25.0K) at $52.00 for $1,300,000, reducing stake from 1.46M to 1.43M shares

Le Peuch Olivier, Chief Executive Officer of SLB LIMITED/NV, executed an open-market sale of 25,000 shares at $52.00 on 2026-02-25, reducing his holdings by 1.7% to 1,434,044 shares post-transaction. The sale occurred near the 52-week high ($51.85), with the stock at $51.66 currently (+3.9% over 30 days, +44.9% over 90 days), suggesting the trade took place during a period of upward momentum. The insider's cross-ticker track record shows only 1 prior sell, with same-ticker history at SLB limited to a prior sell on 2026-01-28 whose outcome is not yet measurable. The company reported revenue of $8,928,000,000 and net income of $739,000,000 in the latest quarter, with a P/E of 30.21 and market cap of $77,248,824,515.10; however, annual revenue declined 1.6% year-over-year. The modest sale size relative to his 1.43M remaining shares and sparse prior selling activity at this ticker provide limited basis for pattern interpretation.

SLB CEO Le Peuch sold 25,000 shares at $50.40 for $1.3M, retaining 1.46M shares post-transaction

CEO Le Peuch sold 25,000 shares (25.0K shares) at $50.40 on 2026-01-28, representing a -1.7% reduction in his holdings of 1,484,044 shares. The sale occurred near the 52-week high of $50.66 and well above the current price of $48.87, suggesting execution at a favorable price point in the context of recent momentum. The company carries a P/E of 28.58 against annual revenue growth of -1.6%, a combination that warrants attention to the cost of capital relative to organic growth. The CEO's retention of 1,459,044 shares (1.46M shares) post-transaction indicates substantial personal economic alignment, though the modest scale of the sale leaves the overall directional signal ambiguous without additional context on his recent activity or scheduled trading arrangements.

SLB CFO Stephane Biguet sells 61,017 shares at $49.70; stock at 52-week high, prior sales at this ticker were well-timed

Stephane Biguet, EVP & CFO of SLB Limited/NV, sold 61,017 shares at $49.70 on 2026-01-26 for total value of $3,032,544.90, reducing holdings by 28.2% from 216,565 shares to 155,548 shares. The sale occurred with SLB trading at its 52-week high of $50.66, after a 34.1% surge over the prior 30 days and 37.6% over 90 days. Notably, across Biguet's four prior SLB trades, three were well-timed at the 90-day mark (stock declined after each sale), most recently on 2025-01-21 where the stock fell 21.1% over the subsequent 90 days. This consistent timing pattern at the same ticker warrants attention as a potential signal of threshold-based decision-making or market awareness, particularly given the stock's current position at its annual peak. The P/E of 29.63 and annual revenue decline of 1.6% provide contextual fundamentals for evaluating whether the timing reflects broader valuation concerns.

EVP Merad Abdellah sells 60,000 SLB shares ($3.0M) at $49.70; stock now at $50.66, near 52-week high.

Merad Abdellah, EVP of Core Services & Equipment, sold 60,000 shares (−29.9% of his pre-transaction holdings) at $49.70 on 2026-01-26 for $2,982,000. The stock has since appreciated 0.0% from the 52-week high of $50.66 and is up +34.1% over the prior 30 days and +37.6% over 90 days. Across his same-ticker history at SLB, Abdellah's prior three completed sales were well-timed at the 90-day horizon (3 of 3 measured outcomes showed negative 90-day returns after each sale), suggesting a demonstrated pattern of selling before subsequent declines. However, this particular sale occurred near the 52-week high, and the stock's strong recent momentum (up +34.1% in 30 days) occurred after the transaction, making this sale's timing outcome not yet conclusive as measurable outcomes remain pending. The company trades at a P/E of 29.63 on $8.9B quarterly revenue with annual revenue growth of −1.6%, contextualizing the transaction within a mature, high-valuation environment.

SLB CLO Ralston sold 18,617 shares at $49.50 on 2026-01-26 for $921,541.50; holds 224,097 shares post-transaction.

Ralston Dianne B., Chief Legal Officer & Secretary of SLB, sold 18,617 shares (-7.7% of pre-transaction holdings) at $49.50, reducing her position from 242,714 to 224,097 shares. The transaction came as SLB stock trades near its 52-week high of $50.66, having appreciated 34.1% over the prior 30 days and 37.6% over 90 days. Her cross-ticker track record across all tickers shows 2 prior sells with a 50.00% well-timed rate at the 90-day mark and an average 90-day return of -4.7%, but at SLB specifically her timing has been mixed: one prior 90-day sale outcome was negative (-21.2% on the 2025-01-21 sell) while the other was positive (+11.8% on the 2025-09-12 sell). The sale occurs against a backdrop of modest fundamentals—SLB reported $8.9B in quarterly revenue and $739.0M in net income, with annual revenue declining 1.6% year-over-year and a P/E of 29.63. The transaction represents a discretionary reduction of equity exposure at elevated valuations rather than a substantial portfolio restructuring.

SLB CFO Stephane Biguet sells 38,447 shares for $1.4M; prior three trades at SLB all showed negative 90-day returns.

Stephane Biguet, EVP & CFO of SLB Limited, sold 38,447 shares at $36.75 on 2025-11-13, reducing his holdings by 18.0% from 214.1K to 175.7K shares.

The current stock is trading at $36.94, down 16.7% from its 52-week high of $44.33, though up 13.4% over the past 30 days.

The insider's historical pattern warrants attention as the stock approaches a 90-day evaluation window.
