To Our Valued Shareholders

Fellow Shareholders:

Thank you for your continued confidence in Halliburton. On behalf of our Board of Directors, management team, and more

than 46,000 empl oyees worldwide, we appreciate your investment.

In 2025, Halliburton delivered solid results through clear strategy and disciplined execution. We generated$22.2 billion in

total company revenue. We achieved another year of strong free cash flow through cost and capital discipline. We returned

$1.6 billion, or nearly 85% of our free cash flow, to shareholders in dividends and share repurchases, underscoring our

priority to return cash to shareholders.

We see a strong future for our business. We expect oil and gas will remain essential in the global energy mix for decades to

come. The shift from idealism to pragmatism reflects reality and creates opportunity. Our strategy is clear: deliver profitable

international growth, maximize value in North America, increase capital efficiency, deploy digital and automation solutions,

and advance a sustainable energy future.

In all markets, our value proposition–to collaborate and engineer solutions to maximize asset value for our customers–

enables us to deliver leading returns and capitalize on future growth opportunities. In international markets, our technology

performs, and our growth engines provide a clear line of sight to outgrow the market. In North America, we will maximize

value by prioritizing returns and by deploying differentiated technologies that solve for our customers’ greatest opportunities.

Your vote is important regardless of how many shares you own. We invite you to attend our Annual Meeting on

May 20, 2026, at our corporate office in Houston, Texas. Whether or not you are able to join us in person, please review

the proxy materials and vote as soon as possible. You may vote by phone, online, or if you received a paper proxy, through

the mail. See the Notice of Annual Meeting for instructions on how to vote.

On behalf of the Board of Directors, thank you for your confidence in Halliburton.

Sincerely,
