Oilfield services provider Halliburton (HAL.N) missed analysts' estimates for third-quarter profit on Thursday, weighed down by a slowdown in drilling activity in North America and the impact of a previously disclosed hack.
The company's shares slipped 1.5% to $30.05 in premarket trading.
Halliburton in August disclosed a cyberattack where an unauthorized third party accessed and removed data from its systems. The incident had caused disruptions and limited access to portions of its business applications.
The company recorded a pre-tax charge of $35 million in the quarter linked to expenses from the attack.
"We experienced a $0.02 per share impact to our adjusted earnings from lost or delayed revenue due to the August cybersecurity event and storms in the Gulf of Mexico," said Halliburton CEO Jeff Miller.
The Houston-based firm posted an adjusted profit of 73 cents per share for the three months ended Sept. 30, missing analysts' average estimate of 75 cents, according to data compiled by LSEG.
Meanwhile, Halliburton's North America revenue fell 8.5% to $2.39 billion.
The decline was primarily driven by decreased pressure pumping services in U.S. land, in addition to lower activity across product service lines in the Gulf of Mexico partly due to hurricanes Francine and Helene.
In contrast, revenue from international markets rose 3.6% to $3.31 billion.
Exploration and drilling in international markets such as the Middle East and Asia have driven increased demand for oilfield services, as producers seek to secure new oil and gas deposits.
Halliburton's rivals Baker Hughes (BKR.O) and SLB (SLB.N) posted third-quarter profit beat on sustained demand from international markets.
