SLB Shares Climb 1.95% Following Significant Subsea Agreement with PTTEP; 870M Trading Volume Places 117th in Market Turnover

Market Overview

On March 10, 2026, SLB (NYSE: SLB) finished the trading day up 1.95%, surpassing the performance of major market indices. The stock traded $0.87 billion in volume, placing it 117th in market activity rankings. This upward movement was driven by news of a substantial contract secured by SLB’s OneSubsea joint venture, which boosted investor optimism regarding the company’s short-term revenue prospects and operational strength in the subsea energy industry.

Main Factors Influencing Performance

SLB’s OneSubsea joint venture recently landed a significant engineering, procurement, and construction (EPC) contract with PTTEP Sabah Oil Limited, a subsidiary of Thailand’s PTT Exploration and Production Public Company Limited (PTTEP). This agreement, part of PTTEP’s ongoing deepwater expansion in Malaysia, is the third major subsea production system (SPS) contract awarded to SLB OneSubsea by PTTEP within the past year. The contract broadens SLB OneSubsea’s responsibilities in delivering integrated subsea infrastructure for the Kikeh 3B Phase 2 project, including subsea trees, manifolds, and control systems. Scheduled for execution throughout 2026 and 2027, the project will utilize SLB OneSubsea’s manufacturing and service facilities in Malaysia, further strengthening the company’s local supply chain and expertise in deepwater operations.

PTTEP’s continued partnership with SLB OneSubsea highlights the joint venture’s established presence in Malaysia’s deepwater sector. Mads Hjelmeland, CEO of SLB OneSubsea, noted the venture’s twenty-year relationship with PTTEP, positioning it to deliver “safe, efficient, and integrated execution” across recent contracts. This ongoing collaboration reflects strong client confidence and operational dependability—essential qualities for large-scale subsea projects where delays or cost overruns can significantly affect profitability. The Kikeh field, Malaysia’s inaugural deepwater oil and gas development, has benefited from SLB OneSubsea’s equipment since 2007. The current initiative builds upon this foundation, operating at depths of 1,300 to 1,400 meters, underscoring SLB’s advanced engineering capabilities.

This contract also supports SLB’s broader strategic goals related to decarbonization and the energy transition. By increasing local production of high-value subsea equipment in Malaysia, SLB OneSubsea is enhancing regional supply chains and minimizing the environmental impact associated with long-distance logistics. This approach aligns with global trends favoring localized manufacturing and sustainable practices, which are increasingly important to investors and regulators. Furthermore, the project’s focus on integrated digital solutions—such as advanced control systems—positions SLB to benefit from the rising demand for technology-driven oil and gas production, a crucial area for growth during the energy transition.

Although the contract is not expected to immediately impact SLB’s earnings in 2026, as execution will take place over 2026 and 2027, the improved long-term revenue outlook likely contributed to the stock’s recent gains. The agreement also signals strong demand for subsea infrastructure in Southeast Asia, where deepwater exploration remains less developed than in other regions. For SLB, this contract reinforces its leadership in subsea technology and validates its joint venture approach, which brings together expertise from SLB, Aker Solutions, and Subsea7. This partnership structure reduces financial risk and provides access to specialized resources, strengthening SLB’s competitive position in a capital-intensive market.

The announcement comes amid favorable industry conditions, including increasing global energy needs and renewed interest in deepwater projects as shallow reserves decline. SLB’s ability to secure repeat contracts from established clients like PTTEP demonstrates its resilience in a cyclical industry and its capacity to maintain market share during volatile periods. However, the company’s forward-looking statements—such as projected timelines and environmental benefits—are subject to risks like regulatory delays, supply chain challenges, and fluctuating commodity prices. Despite these uncertainties, the immediate market response reflects confidence in SLB’s operational execution and its alignment with long-term energy transition objectives.
