United States Oil Fund, LP

Previous wording

The accountability levels for the Benchmark Oil Futures Contract and other Oil Futures Contracts traded on U.S.-based futures exchanges, such as the NYMEX, are not a fixed ceiling, but rather a threshold above which the NYMEX may exercise greater scrutiny and control over an investor’s positions. The current accountability level for investments for any one month in the Benchmark Oil Futures Contract is 10,000 contracts. In addition, the NYMEX imposes an accountability level for all months of 20,000 net futures contracts for light, sweet crude oil. In addition, the ICE Futures maintains the same accountability levels, position limits and monitoring authority for its futures contracts for light, sweet crude oil contract as the NYMEX. If USO and the Related Public Funds exceed these accountability levels for investments in the futures contracts for light, sweet crude oil, the NYMEX and ICE Futures will monitor such exposure and may ask for further information on USO’s and the Related Public Funds’ activities including the total size of all positions, investment and trading strategy, and the extent of liquidity resources of USO and the Related Public Funds. If deemed necessary by the NYMEX and/or ICE Futures, USO could be required to reduce its aggregate position in Crude Oil Futures CL contracts back to the 10,000 single month and/or 20,000 all month accountability level. As of March 31, 2026, USO held 23,766 NYMEX WTI Crude Oil Futures CL contracts and did not hold any ICE WTI Crude Oil Futures contracts. USO exceeded accountability levels of the NYMEX during the three months ended March 31, 2026, including when it held a maximum of 26,969 Crude Oil Futures CL contracts on the NYMEX, exceeding the “any one” month limit. No action was taken by the NYMEX and USO did not have to reduce the number of positions held.

USO exceeded accountability levels of the NYMEX during the six months ended June 30, 2026, including when it held a maximum of 27,286 Crude Oil Futures CL contracts on the NYMEX, exceeding the “any” month limit. No action was taken by the NYMEX and USO did not have to reduce the number of positions held.

Previous wording

Position limits differ from accountability levels in that they represent fixed limits on the maximum number of futures contracts that any person may hold and cannot allow such limits to be exceeded without express CFTC authority to do so. In addition to accountability levels and position limits that may apply at any time, the NYMEX and ICE Futures impose position limits on contracts held in the last few days of trading in the near month contract to expire. Investors should note that the foregoing accountability levels and position limits are subject to change, which in turn could change the amount and type of permitted investments in which USO invests. For the three months ended March 31, 2026, USO did not exceed any position limits imposed by the NYMEX and ICE Futures. The foregoing accountability levels and position limits are subject to change. Due to evolving market conditions, remaining within relevant accountability levels and position limits, and, any additional or different risk mitigation measures taken by USO’s FCMs in the future with respect to USO acquiring additional Oil Futures contracts, USO has invested and intends to invest in other permitted investments, beyond the Benchmark Oil Futures Contract.

Crude oil futures prices were volatile during the three months ended March 31, 2026. The price of the Benchmark Oil Futures Contract started the period at $57.42 per barrel. The high of the period was on March 30, 2026 when the price reached $102.88 per barrel. The low of the period was on January 7, 2026 when the price dropped to $55.94 per barrel. The period ended with the Benchmark Oil Futures Contract at $101.38 per barrel, an increase of approximately 76.56% over the period. USO’s per share NAV began the period at $69.10 and ended the period at $126.39 on March 31, 2026, an increase of approximately 82.91% over the period. The Benchmark Oil Futures Contract prices listed above began with the February 2026 contracts and ended with the May 2026 contracts. The increase of approximately 76.56% on the Benchmark Oil Futures Contract listed above is a hypothetical return only and could not actually be achieved by an investor holding Oil Futures Contracts. An investment in Oil Futures Contracts would need to be rolled forward during the time period described in order to simulate such a result. Furthermore, the change in the nominal price of these differing Oil Futures Contracts, measured from the start of the year to the end of the year, does not represent the actual benchmark results that USO seeks to track, which are more fully described below in the section titled “Tracking USO’s Benchmark.”

For the 30-valuation days ended March 31, 2026, the average daily change in the Benchmark Oil Futures Contract was 1.822%, while the average daily change in the per share NAV of USO over the same time period was 1.832%. The average daily difference was 0.010%% (or 1.0 basis points, where 1 basis point equals 1/100 of 1%), meaning that over this time period USO’s NAV performed within the plus or minus 10% range established as its benchmark tracking goal.

Current wording

For the 30-valuation days ended June 30, 2026, the average daily change in the Benchmark Oil Futures Contract was (1.090)%, while the average daily change in the per share NAV of USO over the same time period was (1.079)%. The average daily difference was 0.011% (or 1.1 basis points, where 1 basis point equals 1/100 of 1%), meaning that over this time period USO’s NAV performed within the plus or minus 10% range established as its benchmark tracking goal.

Since the commencement of the offering of USO’s shares to the public on April 10, 2006 to March 31, 2026, the average daily change in the Benchmark Oil Futures Contract was 0.014%, while the average daily change in the per share NAV of USO over the same time period was 0.003%. The average daily difference was 0.011% (or 1.1 basis points, where 1 basis point equals 1/100 of 1%), meaning that over this time period USO’s NAV performed within the plus or minus 10% range established as its benchmark tracking goal.

Previous wording

For the three months ended March 31, 2026, the actual total return of USO as measured by changes in its per share NAV was 82.91%. This is based on an initial per share NAV of $69.10 as of December 31, 2025 and an ending per share NAV as of March 31, 2026 of $126.39. During this time period, USO made no distributions to its shareholders. However, if USO’s daily changes in its per share NAV had instead exactly tracked the changes in the daily total return of the Benchmark Oil Futures Contract, USO would have had an estimated per share NAV of $125.62 as of March 31, 2026, for a total return over the relevant time period of 81.80%. The difference between the actual per share NAV total return of USO of 82.91% and the expected total return based on the Benchmark Oil Futures Contract of 81.80% was a difference over the time period of 1.11%, which is to say that USO’s actual total return outperformed its benchmark by that percentage. USO incurs expenses primarily composed of the management fee, brokerage commissions for the buying and selling of futures contracts, and other expenses. The impact of these expenses, offset by interest and dividend income, and net of positive or negative execution, and net the difference in returns between USO’s current holdings and the Benchmark Oil Futures contract tended to cause daily changes in the per share NAV of USO to track slightly higher/lower than daily changes in the price of the Benchmark Oil Futures Contract.

Current wording

For the six months ended June 30, 2026, the actual total return of USO as measured by changes in its per share NAV was 52.68%. This is based on an initial per share NAV of $69.10 as of December 31, 2025 and an ending per share NAV as of June 30, 2026 of $105.50. During this time period, USO made no distributions to its shareholders. However, if USO’s daily changes in its per share NAV had instead exactly tracked the changes in the daily total return of the Benchmark Oil Futures Contract, USO would have had an estimated per share NAV of $104.09 as of June 30, 2026, for a total return over the relevant time period of 50.63%. The difference between the actual per share NAV total return of USO of 52.68% and the expected total return based on the Benchmark Oil Futures Contract of 50.63% was a difference over the time period of 2.05%, which is to say that USO’s actual total return outperformed its benchmark by that percentage. USO incurs expenses primarily composed of the management fee, brokerage commissions for the buying and selling of futures contracts, and other expenses. The impact of these expenses, offset by interest and dividend income, and net of positive or negative execution, and net the difference in returns between USO’s current holdings and the Benchmark Oil Futures Contract tended to cause daily changes in the per share NAV of USO to track slightly higher than daily changes in the price of the Benchmark Oil Futures Contract.

By comparison, for the three months ended March 31, 2025, the actual total return of USO as measured by changes in its per share NAV was 2.52%. This is based on an initial per share NAV of $75.45 as of December 31, 2024 and an ending per share NAV as of March 31, 2025 of $77.35. During this time period, USO made no distributions to its shareholders. However, if USO’s daily changes in its per share NAV had instead exactly tracked the changes in the daily total return of the Benchmark Oil Futures Contract, USO would have had an estimated per share NAV of $76.16 as of March 31, 2025, for a total return over the relevant time period of 0.94%. The difference between the actual per share NAV total return of USO of 2.52% and the expected total return based on the Benchmark Oil Futures Contract of 0.94% was a difference over the time period of 1.58%, which is to say that USO’s actual total return outperformed its benchmark by that percentage. USO incurs expenses primarily composed of the management fee, brokerage commissions for the buying and selling of futures contracts, and other expenses.

By comparison, for the six months ended June 30, 2025, the actual total return of USO as measured by changes in its per share NAV was (2.92)%. This is based on an initial per share NAV of $75.45 as of December 31, 2024 and an ending per share NAV as of June 30, 2025 of $73.25. During this time period, USO made no distributions to its shareholders. However, if USO’s daily changes in its per share NAV had instead exactly tracked the changes in the daily total return of the Benchmark Oil Futures Contract, USO would have had an estimated per share NAV of $71.59 as of June 30, 2025, for a total return over the relevant time period of (5.12)%. The difference between the actual per share NAV total return of USO of (2.92)% and the expected total return based on the Benchmark Oil Futures Contract of (5.12)% was a difference over the time period of 2.20%, which is to say that USO’s actual total return outperformed its benchmark by that percentage.

Previous wording

First, USO may buy or sell its holdings in the then current Benchmark Oil Futures Contract at a price other than the settlement price of that contract on the day during which USO executes the trade. In that case, USO may pay a price that is higher or lower, than the closing settlement price of the Benchmark Oil Futures Contract, which could cause the changes in the daily per share NAV of USO to either be higher or lower relative to the daily changes in the Benchmark Oil Futures Contract. During the three months ended March 31, 2026, USCF attempted to minimize the effect of these transactions by seeking to execute its purchase or sale of Oil Futures Contracts at, or as close as possible to, the end of the day settlement price. However, it may not always be possible for USO to obtain the settlement price and there is no assurance that failure to obtain the closing settlement price in the future will not adversely impact USO’s attempt to track the Benchmark Oil Futures Contract.

Second, USO incurs expenses primarily composed of the management fee, brokerage commissions for the buying and selling of futures contracts, and other expenses. The impact of these expenses tends to cause daily changes in the per share NAV of USO to track slightly lower than daily changes in the price of the Benchmark Oil Futures Contract. At the same time, USO earns dividend and interest income on its cash, cash equivalents and Treasuries. USO is not required to distribute any portion of its income to its shareholders and did not make any distributions to shareholders during the three months ended March 31, 2026. Interest payments, and any other income, were retained within the portfolio and added to USO’s NAV. When this income exceeds the level of USO’s expenses for its management fee, brokerage commissions and other expenses (including ongoing registration fees, licensing fees and the fees and expenses of the independent directors of USCF), USO will realize a net yield that will tend to cause daily changes in the per share NAV of USO to track slightly higher than daily changes in the Benchmark Oil Futures Contract. If short-term interest rates rise above these levels, the level of deviation created by the yield would increase. Conversely, if short-term interest rates were to decline, the amount of error created by the yield would decrease. When short-term yields drop to a level lower than the combined expenses of the management fee and the brokerage commissions, then the tracking error becomes a negative number and would tend to cause the daily returns of the per share NAV to underperform the daily returns of the Benchmark Oil Futures Contract. USCF anticipates that interest rates may continue to stagnate over the near future. It is anticipated that fees and expenses paid by USO may continue to be lower than interest earned by USO. As such, USCF anticipates that USO could possibly outperform its benchmark so long as interest earned is greater than the fees and expenses paid by USO.

Third, USO may hold Other Oil-Related Investments in its portfolio that may fail to closely track the Benchmark Oil Futures Contract’s total return movements. In that case, the error in tracking the Benchmark Oil Futures Contract could result in daily changes in the per share NAV of USO that are either too high, or too low, relative to the daily changes in the Benchmark Oil Futures Contract. During the three months ended March 31, 2026, USO held OTC swaps, which are considered Other Oil-Related Investments. If USO increases in size, and due to its obligations to comply with market conditions, regulatory limits, and risk mitigation measures imposed by its FCMs, USO may invest in additional Other Oil-Related Investments, such as OTC swaps, which may have the effect of increasing transaction related expenses and may result in increased tracking error. OTC swaps increase transaction-related expenses due to the fact that USO must pay to the swap counterparty certain fees that USO does not have to pay for transactions executed on an exchange.

Previous wording

The Iran War was the primary driver of crude oil prices during the first quarter of 2026. Global crude oil supply exceeded demand in January and February of 2026. Supply plunged below demand after the start of hostilities and Iran’s closure of the Strait of Hormuz, which threatens approximately 20% of the world’s oil supply. The U.S. Energy Information Association estimated that Iraq, Saudi Arabia, Kuwait, the United Arab Emirates, Qatar, and Bahrain collectively shut in 7.5 million barrels per day (mbd) of crude oil production by March 31, 2026. The daily amount of crude oil supply impacted by the war is expected to increase the longer the Strait of Hormuz remains closed and infrastructure in oil producing countries remains offline. U.S. crude oil production averaged approximately 13.7 mbd in the first quarter of 2026, down from an all-time high of 13.8 mbd reached in October of 2025. However, U.S. production has increased significantly over the last five years. OPEC crude production, which had been rising since 2024, dropped significantly from 29.6 mbd in February to 22.1 mbd in March. OPEC output had been rising prior to the war as the cartel continued to gradually unwind voluntary cuts and quotas that were established to support market prices between 2022 and 2024. Russia and OPEC have still not returned to pre-pandemic production levels, while the U.S. has become the world’s largest crude oil producing nation and other oil producing nations have also increased their output. In the U.S., the Trump administration has aggressively called for increased domestic production, and its actions have and will continue to make more drilling possible. However, U.S. drillers have shown restraint in recent years, so production may not rise as much in the future as it has in the recent past. Technology, geology, and economics tend to be larger determinants of U.S. production levels than political policy. The potential impact of the Iran war on producer’s appetites for increased drilling remains uncertain. Other Trump administration policies have introduced uncertainty into crude oil markets, including on-and-off tariffs and tariff threats. The overall impact of the administration’s actions could increase the risk of a global economic slowdown or recession, which could reduce demand for crude oil. Ongoing global tensions, with existing and potential conflicts in various regions, could increase supply disruptions, which could raise prices. Conversely, any resolution of geopolitical conflicts could further ease supply disruptions, sanctions, and price volatility, which could lower prices.

Current wording

U.S. crude oil production remained near record levels, averaging approximately 13.7 mbd in the second quarter of 2026. U.S. production has increased significantly over the last five years. Conversely, Bloomberg data shows that OPEC crude production dropped from 29.6 mbd in February to a low of 16.4 mbd in late spring. OPEC output had been rising prior to the war as the cartel continued to gradually unwind voluntary cuts and quotas that were established to support market prices between 2022 and 2024. Russia and OPEC have still not returned to pre-pandemic production levels, while the U.S. has become the world's largest crude oil producing nation and other oil producing nations have also increased their output. In the U.S., the Trump administration has encouraged increased domestic production, and its actions may facilitate more drilling activity. However, U.S. drillers have shown restraint in recent years, so production may not rise as much in the future as it has in the recent past. Technology, geology, and economics tend to be significant determinants of U.S. production levels. Increased global demand for U.S. crude, if it is sustained over the long-term, could also motivate increased drilling. Other Trump administration policies have introduced uncertainty into crude oil markets, including tariffs and tariff threats. If the administration's actions increase the risk of a global economic slowdown or recession, demand for crude oil could decline. Ongoing global tensions, with existing and potential conflicts in various regions, could increase supply disruptions, which could raise prices. Conversely, any resolution of geopolitical conflicts could further ease supply disruptions, sanctions, and price volatility, which could lower prices.

USO currently generates cash primarily from: (i) the sale of baskets consisting of 100,000 shares (“Creation Baskets”) and (ii) income earned on Treasuries, cash and/or cash equivalents. USO has allocated substantially all of its net assets to trading in Oil Interests. USO invests in Oil Interests to the fullest extent possible without being leveraged or unable to satisfy its current or potential margin or collateral obligations with respect to its investments in Oil Futures Contracts and Other Oil-Related Investments. A significant portion of USO’s NAV is held in cash and cash equivalents that are used as margin and as collateral for its trading in Oil Interests. The balance of the assets is held in USO’s account at its custodian bank and in investments in money market funds and Treasuries at the FCMs. Income received from USO’s investments in money market funds and Treasuries is paid to USO. During the three months ended March 31, 2026, USO’s expenses did not exceed the income USO earned and the cash earned from the sale of Creation Baskets and the redemption of Redemption Baskets. During the three months ended March 31, 2026, USO did not use other assets to pay expenses. To the extent income exceeds expenses, USO’s NAV will be positively impacted.

USO invests in Oil Interests to the fullest extent possible without being leveraged or unable to satisfy its current or potential margin or collateral obligations with respect to its investments in Oil Futures Contracts and Other Oil-Related Investments. A significant portion of USO’s NAV is held in cash and cash equivalents that are used as margin and as collateral for its trading in Oil Interests. The balance of the assets is held in USO’s account at its custodian bank and in investments in money market funds and Treasuries at the FCMs. Income received from USO’s investments in money market funds and Treasuries is paid to USO. During the six months ended June 30, 2026, USO’s expenses did not exceed the income USO earned and the cash earned from the sale of Creation Baskets and the redemption of Redemption Baskets. During the six months ended June 30, 2026, USO did not use other assets to pay expenses. To the extent income exceeds expenses, USO’s NAV will be positively impacted.

Previous wording

USO’s investments in Oil Interests may be subject to periods of illiquidity because of market conditions, regulatory considerations and other reasons. For example, most commodity exchanges limit the fluctuations in futures contracts prices during a single day by regulations referred to as “daily limits.” During a single day, no trades may be executed at prices beyond the daily limit. Once the price of a futures contract has increased or decreased by an amount equal to the daily limit, positions in the contracts can neither be taken nor liquidated unless the traders are willing to effect trades at or within the specified daily limit. Such market conditions could prevent USO from promptly liquidating its positions in Futures Contracts. During the three months ended March 31, 2026, USO did not purchase or liquidate any of its positions while daily limits were in effect; however, USO cannot predict whether such an event may occur in the future.

USCF attempts to manage the credit risk of USO by following various trading limitations and policies. In particular, USO generally posts margin and/or holds liquid assets that are approximately equal to the market value of its obligations to counterparties under the Oil Futures Contracts and Other Oil-Related Investments it holds. USCF has implemented procedures that include, but are not limited to, executing and clearing trades only with creditworthy parties and/or requiring the posting of collateral or margin by such parties for the benefit of USO to limit its credit exposure. An FCM, when acting on behalf of USO in accepting orders to purchase or sell Oil Futures Contracts on United States exchanges, is required by CFTC regulations to separately account for and segregate as belonging to USO, all assets of USO relating to domestic Oil Futures Contracts trading. These FCMs are not allowed to commingle USO’s assets with their other assets. In addition, the CFTC requires FCMs to hold in a secure account USO’s assets related to foreign Oil Futures Contracts and, in some cases, to cleared swaps executed through the FCMs. Similarly, under its current OTC agreements, USO requires that collateral it posts or receives be posted with its custodian, and under agreements among the custodian, USO and its counterparties, such collateral is segregated.
