HALLIBURTON CO

We are exposed to market risks primarily associated with changes in foreign currency exchange rates. We selectively

manage these exposures through the use of derivative instruments, including forward foreign exchange contracts and foreign

exchange options. The objective of our risk management strategy is to minimize the volatility from fluctuations in foreign

currency. We do not use derivative instruments for trading purposes. The counterparties to our forward contracts and options

are global commercial and investment banks.

We use a sensitivity analysis model to measure the impact of potential adverse movements in foreign currency

exchange rates. With respect to foreign exchange sensitivity, after consideration of the impact from our forward foreign

exchange contracts and options, a hypothetical 10% adverse change in the value of all our foreign currency positions relative to

the U.S. dollar as of December 31,2025 would result in a$81 million, pre-tax loss for our net monetary assets denominated in

currencies other than U.S. dollars.

There are certain limitations inherent in the sensitivity analysis presented, primarily due to the assumption that

exchange rates change instantaneously in an equally adverse fashion. In addition, the analysis is unable to reflect the complex

market reactions that normally would arise from the market shifts modeled. While this is our best estimate of the impact of the

various scenarios, this estimate should not be vieweda forecast.
