United States Oil Fund LP

There have been no material changes to the risk factors previously disclosed in USO’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed on February 29, 2024 (the “Form 10-K”), except as follows:

The Russia-Ukraine war and sanctions brought by the United States and other countries against Russia and others, the terror attacks by Hamas on Israel and ensuing conflict in the Middle East, and other geopolitical tensions, political unrest, and attacks or threats of attack by terrorists, are factors that could contribute to supply constraints, worker shortages, infrastructure and manufacturing energy usage and increase volatility in certain commodity prices. The Russia-Ukraine war and sanctions have adversely impacted and are expected to continue to adversely impact the economies of Russia and Ukraine. In addition, the Russia-Ukraine war and the Middle East conflict, any sanctions, future market or supply disruptions, and the potential for wider conflicts may increase financial market volatility

generally, have severe adverse effects on regional and global economic markets, and could lead to further volatility, including in the markets for commodities, commodity futures, and the NAV or share price of USO.

However, if a resolution to the conflicts were to occur, volatility could decrease and prices could decline in a short period of time. The longer-term impact on commodities and futures prices, including the prices of the Benchmark Oil Futures Contracts, is difficult to predict and depends on a number of factors that may have a negative impact on USO in the future.
