Halliburton Q3 revenue rises 1.8% to $5.70B as international strength lifts margins

Halliburton reported third-quarter 2026 revenue of $5.70 billion, up 1.8% year on year and above analyst estimates of $5.59 billion. Adjusted earnings per share were $0.60, against expectations of $0.58. Operating margin rose to 10.9% from 6.4% a year earlier. Adjusted EBITDA was $1.03 billion, an 18% margin. Strong international demand, led by the Middle East and Latin America, drove the results, while North American hydraulic fracturing stayed soft. Chief executive officer Jeffrey Allen Miller said business outside North America fracturing is "the strongest they have been in many years." The company expects mid-single-digit revenue growth next year and assumes flat North American activity. About half of its margin improvement is expected to come from cost savings.

Halliburton Q3 revenue hits $5.7B as international growth offsets North America slump

Halliburton reported third-quarter 2026 revenue of $5.7 billion, ahead of expectations, with adjusted operating income of $731 million. International revenue rose 9% year-over-year to $3.5 billion, while North America fell 9% to $2.2 billion as the frac market failed to recover as expected. The company repurchased about $250 million of stock and spent $266 million on capital expenditures. Free cash flow fell from the second quarter, hit by lower collections and inventory build-up tied to its SAP implementation. For the fourth quarter, Halliburton expects flat revenue of about $5.7 billion and earnings per share of $0.62 to $0.64. For 2027, it forecasts mid-single-digit revenue growth and operating margins up about 200 basis points to roughly 15%, helped by cost savings and new contract startups.

Halliburton targets mid-single-digit 2027 growth and $500M–$600M profit gain without a frac rebound

Halliburton expects mid-single-digit revenue growth in 2027, it said on its third-quarter earnings call on October 20, 2026. The energy services provider plans this without any recovery in North American hydraulic fracturing. It projects operating margins to rise by 2 percentage points, or 200 basis points, yielding $500 million to $600 million in operating profit. About half of that comes from structural cost cuts and the wind-down of its SAP S/4 software programme. Revenue should end 2026 near $22.5 billion, with about $1 billion more in 2027. International markets are also set to add growth. Halliburton generated revenue in Venezuela in the third quarter across multiple product lines, and chief operating officer Shannon Slocum expects solid growth there.

Halliburton targets 200bps margin gain in 2027 as North America revenue falls 9% in Q3

Halliburton said international revenue rose 3% year over year in the third quarter of 2026, while North America revenue fell 9%. The company blamed a softer-than-expected hydraulic fracturing market and downtime while it moved crews to higher-priced contracts. For 2027, management expects mid-single-digit revenue growth and about 200 basis points of operating margin expansion, to roughly 15%. About half should come from structural cost savings, including $120 million to $150 million from its SAP S/4 transition and $100 million to $150 million from operational rightsizing. The company repurchased about $250 million of stock in the quarter. It is on track to add $3 billion in annual revenue by 2028 from four international growth engines. Management also sees Venezuela as a major opportunity, noting that the market was historically a $5 billion business for Halliburton.

Halliburton targets 15% operating margin in 2027 after $5.7B third-quarter revenue

Halliburton expects revenue to grow at a mid-single-digit rate in 2027, with operating margin reaching about 15%, up roughly 2 percentage points. Chief executive Jeff Miller said the outlook assumes a flat North American market and needs no recovery in hydraulic fracturing. Third-quarter revenue was $5.7 billion, broadly unchanged from the second quarter. Adjusted earnings per share rose to $0.60 from $0.55, and adjusted net income increased to $501 million from $461 million. Net income fell to $417 million from $534 million, after $107 million in pre-tax charges, mainly for severance and an inventory write-down. North American revenue fell 5% to $2.2 billion, while international revenue rose 3% to $3.5 billion. Free cash flow was $156 million, and the company bought back about $250 million of shares.
