Agility's contracts with the US army were not limited to Iraq and stretched to other areas such as Afghanistan and Germany, Sultan said, also mitigating the impact of any pullout.
Senior US officials said on Thursday the new administration of President Barack Obama had not yet decided whether to withdraw combat troops from Iraq in 16 months, as he promised during his election campaign.
Agility, the Gulf's biggest logistics firm, has spent billions of dollars on acquisitions in the past few years and now operates in 100 countries, according to its website.
The firm has bought a string of logistics companies in Asia and other emerging markets to reduce its dependence on US government deals to feed troops in Iraq and Afghanistan.
Global Investment House expects Agility's fourth-quarter net profit to fall by 12.4 per cent, according to a Reuters survey last month.
Sultan said the firm met its 2008 revenue target of $7 billion.
