Halliburton, an American oil service company, has reported a significant sequential improvement in its fourth-quarter (Q4) 2025 earnings, posting a net income of $589 million, compared to $18 million in the previous quarter, according to a press release by the company.

Jeff Miller, Chairman, President, and CEO of Halliburton, attributed the strong finish to the year to the company’s strategy and resilient international franchise.

Excluding impairments and tax adjustments, the company’s adjusted net income reached $576 million, up from the adjusted $496 million reported in the third quarter (Q3). Revenue for the quarter climbed to $5.7 billion, while adjusted operating income surged to $829 million.

For the full year of 2025, Halliburton generated $22.2 billion in total revenue, a slight decline from the $22.9 billion recorded in 2024. Adjusted operating income for the year stood at $3.1 billion, compared to $3.9 billion in the prior year. Despite the year-over-year (YoY) dip, the company returned 85% of its free cash flow to shareholders, including $1 billion in share repurchases.

Regional performance highlighted a divergence between international and domestic markets. Revenue from the Europe, Africa, and Commonwealth of Independent States (CIS) region, which includes nations such as Kazakhstan, Azerbaijan, and Uzbekistan, jumped 12% sequentially to $928 million.

This growth was driven by higher completion tool sales in the North Sea, improved well construction in Africa, and increased stimulation activity in Angola. Similarly, Middle East and Asia revenue rose 3% to $1.5 billion, boosted by well interventions in Saudi Arabia and stimulation projects in the UAE.

Founded in 1919 by Erle P. Halliburton in Duncan, Oklahoma, the company has evolved from a pioneering oil well cementing operation into a global leader in drilling, evaluation, and production services. Today, Halliburton employs approximately 48,000 personnel worldwide, maintaining its position as a major innovator in the energy sector.
