Strong Fourth-Quarter Performance as Global Activity Stabilizes

"SLB concluded the year with very strong fourth-quarter results driven by Production Systems, Digital and Reservoir Performance," said SLB Chief Executive Officer Olivier Le Peuch.

"Fourth-quarter revenue increased sequentially across all four geographies for the first time since the second quarter of 2024, reflecting stabilized global upstream activity. We saw revenue growth both in North America and international markets, further supported by an additional month of ChampionX revenue. Strong year-end product and digital sales in Latin America, the Middle East & Asia, Sub-Saharan Africa and offshore North America also contributed to this performance.

"Although 2025 presented a challenging backdrop for the industry - with lower commodity prices, geopolitical uncertainty and an oversupplied oil market - we continued to build resilience across our portfolio by accelerating our strategy. This included a growing emphasis on production and recovery, increased deployment of AI solutions, and the rapid expansion of our Data Center Solutions business.

"For the full year, lower upstream spending resulted in modest declines in revenue and adjusted EBITDA margin. Nevertheless, we delivered strong cash flow performance, generating $6.5 billion of cash flow from operations and $4.1 billion of free cash flow, enabling us to return $4.0 billion to shareholders. The addition of ChampionX activity and growth in the Digital and Data Center Solutions businesses mostly offset notable revenue declines in Saudi Arabia, Mexico and across Sub-Saharan Africa.

"As we move into 2026, we believe that the headwinds we experienced in key regions in 2025 are behind us. In particular, we expect rig activity in the Middle East to increase compared to today's level, and our footprint in the region puts us in a strong position to benefit from this recovery," Le Peuch said.

Industry is Prioritizing Production and Recovery

"As economics remain challenged, production and recovery activity is becoming a strategic priority for our customers in order to unlock incremental barrels at the lowest cost. This is translating into higher demand particularly for intervention services, artificial lift, production chemicals and SLB OneSubsea?.

"We have already benefited from the strategic addition of ChampionX, which contributed $1.5 billion in revenue with accretive margins for the Production Systems Division and the Core since the closing of the acquisition in July 2025. We expect the positive impact of ChampionX to continue to accelerate in 2026 as we capture further synergies and extend its leading capabilities into additional international markets," Le Peuch said.

Digital and Data Center Solutions Creating Pathways for Growth

"Digital revenue increased 9% on a full-year basis with an adjusted EBITDA margin of 35% driven by significant uptake in Digital Operations as well as steady growth in Platforms & Applications as customers continued to invest in AI and automated solutions to improve performance and efficiency. As these solutions become increasingly intertwined with our customers' operations, we were proud to see our Digital annualized recurring revenue (ARR) exceed $1 billion at the end of the fourth quarter which increased 15% year on year.

"Meanwhile, our Data Center Solutions business grew 121% year on year. This business is expanding rapidly as we strengthen strategic partnerships with hyperscalers to deliver modular data center manufacturing solutions.

"We expect that Data Center Solutions will be our fastest growing business for years to come, and Digital will continue to grow at highly accretive margins. Both present differentiated growth opportunities for SLB in 2026 and beyond," said Le Peuch.

Returns to Shareholders to Exceed $4 Billion in 2026

"SLB has consistently proven that the unique strengths of our portfolio enable us to create differentiated value and generate significant cash flow in varied market conditions.

"As we move through the year, we anticipate that activity will gradually improve in the key markets where we operate, giving us the confidence that we will generate strong cash flows, once again, in 2026.

"Aligned with our clear priority to create value for investors, we are committed to returning more than $4 billion to shareholders in 2026 through dividends and share repurchases, and we are starting the year with an increase of 3.5% to our quarterly dividend as approved by our Board of Directors," Le Peuch concluded.

Other Events

For the full year of 2025, SLB repurchased a total of 60 million shares of its common stock for a total purchase price of $2.41 billion.

On January 22, 2026, SLB's Board of Directors approved a 3.5% increase in quarterly cash dividend from $0.285 per share of outstanding common stock to $0.295 per share, beginning with the dividend payable on April 2, 2026, to stockholders of record on February 11, 2026.

Fourth-Quarter Revenue by Geographical Area

Fourth-quarter revenue of $9.75 billion increased 9% sequentially with international revenue increasing 8% and North America revenue increasing 15%. These results reflect a full quarter of activity from the acquired ChampionX businesses, which contributed $879 million of revenue, consisting of $583 million in North America and $266 million in the international markets. Third-quarter 2025 revenue reflects two months of activity from ChampionX, which contributed revenue of $579 million, consisting of $387 million in North America and $171 million in the international markets.

Excluding the impact of this acquisition, international fourth-quarter 2025 revenue increased 7% and North America fourth-quarter 2025 revenue increased 6% sequentially. Fourth-quarter revenue increased sequentially across all geographical areas for the first time since the second quarter of 2024 as global upstream markets have stabilized. Organic sequential revenue growth both in North America and in the international markets was driven by higher offshore activity and strong year-end product and digital sales, most notably in Latin America, the Middle East & Asia, across Sub-Saharan Africa and in the Gulf of America.

International

Latin America

Revenue in Latin America of $1.68 billion increased 12% sequentially, driven by increased sales of completions and subsea production systems in Brazil, as well as the resumption of production in the Asset Peformance Solutions (APS) projects in Ecuador following the prior quarter's pipeline-related disruption.

Year over year, revenue declined 1%, primarily due to a significant reduction in land activity in Mexico, almost fully offset by increased offshore activity in Guyana and robust hydraulic fracturing activity in Argentina.

Europe & Africa

Revenue in Europe & Africa of $2.53 billion increased 3% sequentially, supported by improved activity across deepwater Sub-Saharan Africa and Europe, partially offset by lower activity in North Africa and Scandinavia.

Year over year, revenue declined 1%, as strong activity in Nigeria and Azerbaijan was more than offset by lower activity in North Africa, Europe and Scandinavia.

Middle East & Asia

Revenue in the Middle East & Asia of $3.23 billion increased 7% sequentially, driven by a rebound in Saudi Arabia, along with robust activity in East Asia, Egypt, Australia, United Arab Emirates and Indonesia.

Year over year, revenue decreased 7%, as higher activity in East Asia, Iraq, United Arab Emirates, Oman and India was more than offset by significantly reduced activity in Saudi Arabia.

North America

Revenue in North America of $2.21 billion increased 4% sequentially, due to higher offshore activity driven by increased digital exploration sales, higher drilling activity and increased sales of production systems, while U.S. land revenue remained flat.

Year over year, revenue declined 4%, primarily due to the divestiture of the APS project in Canada in the second quarter of 2025 and a sharp reduction in U.S. land drilling activity, partially offset by growth in Data Center Solutions.

-0- *T 11)What are the revenue categories in the Digital Division that offer solutions to SLB's customers?Within Digital, revenue is generated from four key solutions - Platforms & Applications, Digital Operations, Digital Exploration and Professional Services. Platforms & Applications includes SLB's cloud technologies such as the Delfi? and Lumi platforms, along with a suite of specialized, domain-focused applications such as Petrel? and Techlog? offered as SaaS subscription or perpetual licenses. These platforms and applications automate complex models to simulate the impact of reservoir development plans and aid in the planning of key operations such as drilling, completion and production designs. Additionally, they unlock data and utilize AI and machine learning to reduce cycle time and improve efficiency of workflows to allow customers to make better, faster decisions to improve their project economics and reservoir performance. Revenue is recurring (with exception of one-off license sales) underpinned by a substantial base of ARR from a globally installed base, complemented by customer adoption of new cloud-based capabilities and IoT-enabled solutions. This category has best-in-class retention rates and limited churn. Digital Operations combines the unique strengths of SLB's oilfield services with advanced digital technologies to deliver more reliable, efficient and autonomous field operations. By integrating connected solutions with Performance Live? digital service delivery centers, customers gain real-time monitoring, remote decision making and automated execution across their workflows from autonomous drilling to automated well intervention, all while reducing costs and improving project economics. Revenue is generated from the same customer base as the Core divisions and is, therefore, repeatable. Additionally, a portion of the revenue is recurring in nature. To incentivize the Core divisions - Well Construction, Reservoir Performance and Production Systems - and Digital to develop and promote this category, the resulting revenue is recognized in both the respective Core division as well as in the Digital Division. This effect is eliminated in consolidation. Digital Exploration represents SLB's exploration data business. The exploration data library is a differentiated asset library of seismic surveys and other subsurface data that customers rely on for better exploration and development decisions. These licensed datasets also support carbon storage design and monitoring. The library covers key exploration and producing basins worldwide and datasets are refreshed and reprocessed to benefit from the latest imaging algorithms and AI technologies, enabled by high performance cloud computing. Revenue is generated from one-time, non-transferable license sales and is therefore non-recurring in nature. Professional Services includes consulting and other services required to support customers' digital transformations. These services include transition support from on-prem to cloud-based digital solutions, data clean-up and migration, workflow automation - including deployment of workflow solutions built within SLB's global network of Innovation Factori workspaces - and training to further enable customers' digital transformations. Revenue in this category is largely project-based, and repetitive engagements with the same customers are common. These services generate pull-through opportunities across other digital revenue streams. 12)How much revenue was generated from each of the categories comprising the Digital Division in 2025 and 2024? What is the pretax operating income and adjusted EBITDA of the Digital Division for those periods?Digital revenue, pretax operating income, and adjusted EBITDA in 2025 and 2024 are detailed as follows:*T

This is calculated based on the trailing twelve months revenue and excludes one-time license sales and variable usage fees. ARR as of December 31, 2025, was $1.00 billion, compared to $876 million as of December 31, 2024, resulting in a 15% increase year over year. 14)What is the Data Center Solutions business and where is it reported?The Data Center Solutions business designs and manufactures critical infrastructure components - such as modular data center enclosures, cooling systems and other hardware - for hyperscalers and enterprises. By leveraging scalable, standardized production with rapid lead times, and rigorous quality assurance, SLB provides configurable solutions that balance cost efficiency, reliability and customization to meet accelerating data center demand. AI-driven data demand is fueling rapid growth, and this business is going to be a material and meaningful contributor to SLB's portfolio in the future. This business is reported in All Other category. 15)How much revenue was generated from the Data Center Solutions business?Data Center Solutions revenue was $460 million for the full year of 2025 and $208 million for the full year of 2024, representing a 121% increase year on year. 16)What Divisions comprise SLB's Core business and what were their revenue and pretax operating income for the fourth quarter of 2025, the third quarter of 2025, the fourth quarter of 2024, the full year of 2025 and the full year of 2024?SLB's Core business comprises the Reservoir Performance, Well Construction, and Production Systems Divisions.
