United States Oil Fund, LP - 10-K

Item 1A. Risk Factors.

The following risk factors should be read in connection with the other information included in this annual report on Form 10-K, including Management’s Discussion and Analysis of Financial Condition and Results of Operations and USO’s financial statements and the related notes.

USO’s investment objective is for the daily percentage changes in the NAV per share to reflect the daily percentage changes of the spot price of light, sweet crude oil, as measured by the daily percentage changes in the price of Benchmark Oil Futures Contract, plus interest earned on USO’s collateral holdings, less USO’s expenses. USO seeks to achieve its investment objective by investing so that the average daily percentage change in USO’s NAV for any period of 30 successive valuation days will be within plus/minus ten percent (10%) of the average daily percentage change in the price of the Benchmark Oil Futures Contract over the same period. As a result, investors should be aware that USO would meet its investment objective even if there are significant deviations between changes in its daily NAV and changes in the daily price of the Benchmark Oil Futures Contract provided that the average daily percentage change in USO’s NAV over 30 successive valuation days is within plus/minus ten percent (10%) of the average daily percentage change in the price of the Benchmark Oil Futures Contract over the same period.

Following the significant market volatility that occurred in the Spring of 2020 and the market conditions, regulatory requirements and risk mitigation measures taken by USO and USO’s FCM that impacted USO as a result thereof, USO disclosed its parameters for making decisions regarding the permitted investments USO would hold, including the intended order of priority in selecting investments and the type of investments to be held in its portfolio. Beginning with the monthly roll in September 2023 and ending with the monthly roll in January 2024, USO transitioned its investment portfolio to primarily invest in the Benchmark Oil Futures Contract, consistent with USO’s investment strategy prior to the Spring of 2020. However, USO has had, and will continue to have, the ability to invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract and Other Oil-Related Investments, such as OTC swaps, and USO may make such investments if market conditions (including but not limited to those allowing USO to obtain greater liquidity (i.e., liquidity requirements) or to execute transactions with more favorable pricing), regulatory requirements (including, but not limited to, exchange accountability levels and position limits imposed by NYMEX as well as statutory or regulatory limits), risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants), liquidity requirements, or other factors require USO to do so in order to meet its investment objective. USO may invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract, and/or Other Oil-Related Investments, as a result or in response to any of the foregoing factors.

Table of Contents

USO will continue to disclose its end of day portfolio on its website, www.uscfinvestments.com. The end of day portfolio disclosed on USO’s website would reflect any investments in Oil Futures Contracts beyond the Benchmark Oil Futures Contract, and/or Other Oil-Related Investments, including any made in light of market conditions, regulatory requirements, risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants), liquidity requirements, or other factors. Independent of the USO website, USO may make available portfolio holdings information to Authorized Participants that reflects the Fund’s anticipated holdings on the following business day.

An investment in USO involves investment risk similar to a direct investment in Oil Futures Contracts and Other Oil-Related Investments but it is not a proxy for investing in the oil markets. Investing in USO also involves correlation risk, or the risk that investors purchasing shares to hedge against movements in the price of crude oil will have an efficient hedge only if the price they pay for their shares closely correlates with the price of crude oil. In addition to investment risk and correlation risk, an investment in USO involves tax risks, OTC risks, and other risks.

Investment Risk

The NAV of USO’s shares relates directly to the daily changes in the price of the Benchmark Oil Futures Contracts and other assets held by USO and fluctuations in the prices of these assets could materially adversely affect an investment in USO’s shares. Past performance is not necessarily indicative of future results; all or substantially all of an investment in USO could be lost.

The net assets of USO consist primarily of investments in Oil Futures Contracts and, to a lesser extent, in Other Oil-Related Investments. The NAV of USO’s shares relates directly to the value of these assets (less liabilities, including accrued but unpaid expenses), which in turn relates to the price of light, sweet crude oil in the marketplace. Crude oil prices depend on local, regional and global events or conditions that affect supply and demand for oil.

Economic conditions impacting crude oil. The demand for crude oil correlates closely with general economic growth rates. The occurrence of recessions or other periods of low or negative economic growth will typically have a direct adverse impact on crude oil demand and, therefore, may have an adverse impact on crude oil prices. Other factors that affect general economic conditions in the world or in a major region, such as changes in population growth rates, periods of civil unrest, military conflicts, war (such as the Russia-Ukraine war) pandemics (e.g., the COVID-19 pandemic), government austerity programs, trade wars between nations, or currency exchange rate fluctuations, can also impact the demand for crude oil. Sovereign debt downgrades, defaults, inability to access debt markets due to credit or legal constraints, liquidity crises, the breakup or restructuring of fiscal, monetary, or political systems such as the European Union, and other events or conditions that impair the functioning of financial markets and institutions also may adversely impact the demand for crude oil.

Other crude oil demand-related factors. Other factors that may affect the demand for crude oil and therefore its price, include technological improvements in energy efficiency; seasonal weather patterns, which affect the demand for crude oil associated with heating and cooling; increased competitiveness of alternative energy sources that have so far generally not been competitive with oil without the benefit of government subsidies or mandates; and changes in technology or consumer preferences that alter fuel choices, such as toward alternative fueled vehicles or electric transportation and broad-based changes in personal income levels.

Other crude oil supply-related factors. Crude oil prices also vary depending on a number of factors affecting supply, including geopolitical risk associated with wars (such as the Russia-Ukraine war), terrorist attacks and tensions between countries, including sanctions imposed as a result of the foregoing, any of which can adversely affect crude oil and other energy trade flows by limiting or disrupting trade between countries or regions. World crude oil supplies can also be affected by other factors that reduce available supplies, such as natural disasters, disruptions in competitors’ operations, or unexpected unavailability of distribution channels. Technological change can also alter the relative costs for companies in the crude oil industry to find, produce, and transport crude oil, which in turn may affect the supply of and demand for crude oil. For example, increased supply from the development of new oil supply sources and technologies to enhance recovery from existing sources tends to reduce crude oil prices to the extent such supply increases are not offset by commensurate growth in demand. Similarly, increases in industry refining or petrochemical manufacturing capacity may impact the supply of crude oil.

Other factors impacting the crude oil market. The supply of and demand for crude oil may also be impacted by changes in interest rates, inflation, and other local or regional market conditions, as well as by the development of alternative energy sources.

Table of Contents

Price volatility may possibly cause the total loss of your investment. Futures contracts have a high degree of price variability and are subject to occasional rapid and substantial changes. Consequently, you could lose all or substantially all of your investment in USO. Market volatility is attributable to things like the COVID-19 pandemic and related supply chain disruptions, war (such as the Russia-Ukraine war), continuing disputes among oil-producing countries, the introduction of or changes in tariffs or trade barriers, and trade wars between nations. Events such as these, and others, could cause volatility in the future, which may affect the value, pricing and liquidity of some investments or other assets, including those held by or invested in by USO and the impact of which could limit USO’s ability to have a substantial portion of its assets invested in the Benchmark Oil Futures Contract. In such a circumstance, USO could, if it determined it appropriate to do so in light of market conditions and regulatory requirements, invest in other Futures Contracts and/or Other Oil-Related Investments, such as OTC swaps.

Natural disasters, public health disruptions (such as the COVID-19 pandemic), and international armed conflicts could impact the price of commodities and/or the value, pricing and liquidity of USO’s investments or assets which, in turn, could cause the loss of your investment in USO.

Natural or environmental disasters, such as earthquakes, fires, floods, hurricanes, tsunamis and other severe weather-related phenomena generally, and widespread disease, including public health disruptions, pandemics and epidemics (for example, the COVID-19 pandemic), can be highly disruptive to economies and markets. Such events can, directly or indirectly, negatively impact, and/or cause volatility in, the price of commodities such as crude oil and the value, pricing, and liquidity of the investments or other assets held by USO.

Geopolitical conflict, including war and armed conflicts (such as the Russia-Ukraine war, conflicts in the Middle East, and the expansion of such conflicts in surrounding areas), sanctions, the introduction of or changes in tariffs or trade barriers, global or local recessions, and acts of terrorism, can also, directly or indirectly, negatively impact, and/or cause volatility in, the price of commodities such as crude oil and the value, pricing, and liquidity of the investments or other assets held by USO.

A negative impact on, or volatility in, the price of crude oil or the value, pricing and liquidity of USO’s investments or other assets resulting from the occurrence of any of the aforementioned events, or similar events, could cause you to lose all, or substantially all, of your investment in USO.

Historical performance of USO and the Benchmark Oil Futures Contract is not indicative of future performance.

Past performance of USO or the Benchmark Oil Futures Contract is not necessarily indicative of future results. Therefore, past performance of USO or the Benchmark Oil Futures Contract should not be relied upon in deciding whether to buy shares of USO.

Correlation Risk

An investment in USO may provide little or no diversification benefits. Thus, in a declining market, USO may have no gains to offset losses from other investments, and an investor may suffer losses on an investment in USO while incurring losses with respect to other asset classes.

Investors purchasing shares to hedge against movements in the price of crude oil will have an efficient hedge only if the price investors pay for their shares closely correlates with the price of crude oil. Investing in USO’s shares for hedging purposes includes the following risks:

The market price at which the investor buys or sells shares may be significantly less or more than NAV.

Daily percentage changes in NAV may not closely correlate with daily percentage changes in the price of the Benchmark Oil Futures Contracts.

Daily percentage changes in the price of the Benchmark Oil Futures Contract may not closely correlate with daily percentage changes in the price light, sweet crude oil.

Historically, Oil Futures Contracts and Other Oil-Related Investments have generally been non-correlated to the performance of other asset classes such as stocks and bonds. Non-correlation means that there is a low statistically valid relationship between the performance of futures and other commodity interest transactions, on the one hand, and stocks or bonds, on the other hand.

Table of Contents

However, there can be no assurance that such non-correlation will continue during future periods. If, contrary to historic patterns, USO’s performance were to move in the same general direction as the financial markets, investors will obtain little or no diversification benefits from an investment in USO’s shares. In such a case, USO may have no gains to offset losses from other investments, and investors may suffer losses on their investment in USO at the same time they incur losses with respect to other investments.

Variables such as drought, floods, weather, military conflicts, pandemics (such as the COVID-19 pandemic), embargoes, tariffs and other political events may have a larger impact on crude oil prices and crude oil-linked instruments, including Oil Futures Contracts and Other Oil-Related Investments, than on traditional securities. These additional variables may create additional investment risks that subject USO’s investments to greater volatility than investments in traditional securities.

Non-correlation should not be confused with negative correlation, where the performance of two asset classes would be opposite of each other. There is no historical evidence that the spot price of crude oil and prices of other financial assets, such as stocks and bonds, are negatively correlated. In the absence of negative correlation, USO cannot be expected to be automatically profitable during unfavorable periods for the stock market, or vice versa.

The market price at which investors buy or sell shares may be significantly less or more than NAV.

USO’s NAV per share will change throughout the day as fluctuations occur in the market value of USO’s portfolio investments. The public trading price at which an investor buys or sells shares during the day from their broker may be different from the NAV of the shares, which is also the price shares can be redeemed with USO by Authorized Participants in Redemption Baskets. Generally, price differences may relate to supply and demand forces at work in the secondary trading market for shares that are closely related to, but not identical to, the same forces influencing the prices of light, sweet crude oil and the Benchmark Oil Futures Contract at any point in time. USCF expects that exploitation of certain arbitrage opportunities by Authorized Participants and their clients will tend to cause the public trading price to track NAV per share closely over time, but there can be no assurance of that. For example, a shortage of USO shares in the market and other factors could cause USO’s shares to trade at a premium. Investors should be aware that such premiums can be transitory. To the extent an investor purchases shares that include a premium (e.g., because of a shortage of shares in the market due to the inability of Authorized Participants to purchase additional shares from USO that could be resold into the market) and the cause of the premium no longer exists causing the premium to disappear (e.g., because more shares are available for purchase from USO by Authorized Participants that could be resold into the market) such investor’s return on its investment would be adversely impacted due to the loss of the premium.

The NAV of USO’s shares may also be influenced by non-concurrent trading hours between the NYSE Arca and the various futures exchanges on which light, sweet crude oil is traded. While the shares trade on the NYSE Arca from 9:30 a.m. to 4:00 p.m. Eastern Time, the trading hours for the futures exchanges on which light, sweet crude oil trades may not necessarily coincide during all of this time. For example, while the shares trade on the NYSE Arca until 4:00 p.m. Eastern Time, liquidity in the global light, sweet crude oil market may be reduced after the determination of the settlement price by the NYMEX at 2:30 p.m. Eastern Time. USO’s NAV is calculated based on the settlement price of Oil Futures Contracts at 2:30 p.m. Eastern Time and the closing share price of USO on the NYSE Arca takes into account changes in the price of Oil Futures Contracts that occur after the settlement price is determined. As a result, during periods when the NYSE Arca is open and the futures exchanges on which light, sweet crude oil is traded are closed, trading spreads and the resulting premium or discount on the shares may widen and, therefore, increase the difference between the price of the shares and the NAV of the shares.

Daily percentage changes in USO’s NAV may not correlate with daily percentage changes in the price of the Benchmark Oil Futures Contract.

It is possible that the daily percentage changes in USO’s NAV per share may not closely correlate to daily percentage changes in the price of the Benchmark Oil Futures Contract. Non-correlation may be attributable to disruptions in the market for light, sweet crude oil, the imposition of position or accountability limits by regulators or exchanges, or other extraordinary circumstances. As USO approaches or reaches position limits with respect to the Benchmark Oil Futures Contract and other Oil Futures Contracts or in view of market conditions, regulatory requirements, risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants) and other conditions as described herein, USO has and may invest in Oil Futures Contracts other than the Benchmark Oil Futures Contact and Other Oil-Related Investments which may cause less correlation with daily percentage changes in the price of the Benchmark Oil Futures Contract than investments in the Benchmark Oil Futures Contract. In addition, USO is not able to replicate exactly the changes in the price of the Benchmark Oil Futures Contract because the total return generated by USO is reduced by expenses and transaction costs, including those incurred in connection with USO’s trading activities, and increased by interest income from USO’s holdings of Treasuries (defined below).

Table of Contents

Daily percentage changes in the price of the Benchmark Oil Futures Contract may not correlate with daily percentage changes in the spot price of light, sweet crude oil.

The correlation between changes in price of the Benchmark Oil Futures Contract and the spot price of light, sweet crude oil may at times be only approximate. The degree of imperfection of correlation depends upon circumstances such as variations in the speculative crude oil market, supply of and demand for Oil Futures Contracts (including the Benchmark Oil Futures Contract) and Other Oil-Related Investments, and technical influences in gasoline futures trading.

An investment in USO is not a proxy for investing in the oil markets, and the daily percentage changes in the price of the Benchmark Oil Futures Contract, or the NAV of USO, may not correlate with daily percentage changes in the spot price of light, sweet crude oil .

An investment in USO is not a proxy for investing in the oil markets. To the extent that investors use USO as a means of indirectly investing in crude oil, there is the risk that the daily changes in the price of USO’s shares on the NYSE Arca, on a percentage basis, will not closely track the daily changes in the spot price of light, sweet crude oil on a percentage basis. This could happen if the price of shares traded on the NYSE Arca does not correlate closely with the value of USO’s NAV; the changes in USO’s NAV do not correlate closely with the changes in the price of the Benchmark Oil Futures Contract; or the changes in the price of the Benchmark Oil Futures Contract do not closely correlate with the changes in the cash or spot price of crude oil. This is a risk because if these correlations do not exist, then investors may not be able to use USO as a cost-effective way to indirectly invest in crude oil or as a hedge against the risk of loss in crude oil-related transactions. The degree of correlation among USO’s share price, the price of the Benchmark Oil Futures Contract and the spot price of crude oil depends upon circumstances such as variations in the speculative oil market, supply of and demand for Oil Futures Contracts (including the Benchmark Oil Futures Contract) and Other Oil-Related Investments, and technical influences on trading oil futures contracts. Investors who are not experienced in investing in oil futures contracts or the factors that influence that market or speculative trading in the crude oil markets and may not have the background or ready access to the types of information that investors familiar with these markets may have and, as a result, may be at greater risk of incurring losses from trading in USO shares than such other investors with such experience and resources.

Natural forces in the oil futures market known as “backwardation” and “contango” may increase USO’s tracking error and/or negatively impact total return.

USO’s Benchmark Oil Futures Contract is the near month contract to expire until the near month contract approaches expiration when, over a five-day period beginning on the first business day of each month, the Benchmark Oil Futures Contract transitions to the next month contract to expire and remains that contract until the next roll period. Between roll periods, the near month contract expires and the next near month contract becomes the near month. In the event of a crude oil futures market where near month contracts trade at a higher price than next month to expire contracts, a situation described as “backwardation” in the futures market, then absent the impact of the overall movement in light, sweet crude oil prices the value of the benchmark contract would tend to rise as it approaches expiration. Conversely, in the event of a crude oil futures market where near month contracts trade at a lower price than next month contracts, a situation described as “contango” in the futures market, then absent the impact of the overall movement in crude oil prices, the value of the benchmark contract would tend to decline as it approaches expiration.

While contango and backwardation are consistently present in trading in the futures markets, such conditions can be exacerbated by market forces. For example, extraordinary market conditions in the crude oil markets, including “super contango” (a higher level of contango arising from the overabundance of oil being produced and the limited availability of storage for such excess supply), occurred in the crude oil futures markets in April 2020 due to over-supply of crude oil in the face of weak demand during the COVID-19 pandemic when disputes among oil-producing countries regarding limitations on the production of oil also were occurring.

When compared to total return of other price indices, such as the spot price of crude oil, the impact of backwardation and contango may cause the total return of USO’s per share NAV to vary significantly. Moreover, absent the impact of rising or falling oil prices, a prolonged period of contango could have a significant negative impact on USO’s per share NAV and total return and investors could lose part or all of their investment. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this annual report on Form 10-K for a discussion of the potential effects of contango and backwardation.

Accountability levels, position limits, and daily price fluctuation limits set by the exchanges have the potential to cause tracking error, by limiting USO’s investments, including its ability to fully invest in the Benchmark Oil Futures Contract, which means that changes in the price of shares could substantially vary from the changes in the price of the Benchmark Oil Futures Contract.

Designated contract markets, such as the NYMEX and ICE Futures, have established accountability levels and position limits on the maximum net long or net short futures contracts in commodity interests that any person or group of persons under common trading control (other than as a hedge, which an investment by USO is not) may hold, own or control. These levels and position limits apply to the futures contracts that USO invests in to meet its investment objective. In addition to accountability levels and position limits, the NYMEX and ICE Futures may also set daily price limits on futures contracts. The daily price fluctuation limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price. Once the daily price fluctuation limit has been reached in a particular futures contract, no trades may be made at a price beyond that limit. 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 NYMEX 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 Europe 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 USO’s and the Related Public Funds’ investments in the futures contracts for light, sweet crude oil, the NYMEX and ICE Futures Europe will monitor such exposure and may ask for further information on 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 Europe, USO could be required to reduce its net futures contracts back to the accountability level.

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 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.

Part 150 of the CFTC’s regulations (the “Position Limits Rule”) establishes federal position limits for 25 core referenced futures contracts (comprised of agricultural, energy and metals futures contracts), futures and options linked to the core referenced futures contracts, and swaps that are economically equivalent to the core referenced futures contracts that all market participants must comply with, with certain exemptions.

The Benchmark Oil Futures Contract is subject to position limits under the Position Limits Rule, and USO’s trading does not qualify for an exemption therefrom. Accordingly, the Position Limits Rule could inhibit USO’s ability to invest in the Benchmark Oil Futures Contract and thereby could negatively impact the ability of USO to meet its investment objective.

USO has not limited the size of its offering and intends to utilize substantially all of its proceeds to purchase Oil Futures Contracts and Other Oil-Related Investments to the extent possible. If USO encounters accountability levels, position limits (including those set by the Position Limits Rule), or price fluctuation limits for Oil Futures Contracts on the NYMEX or ICE Futures, it may then, if permitted under applicable regulatory requirements, purchase Oil Futures Contracts on other exchanges that trade listed crude oil futures or enter into swaps or other permitted investments to meet its investment objective. In addition, if USO exceeds accountability levels on either the NYMEX or ICE Futures and is required by such exchanges to reduce its holdings, such reduction could potentially cause a tracking error between the price of USO’s shares and the price of the Benchmark Oil Futures Contract.

Table of Contents

Risk mitigation measures that could be imposed by USO’s FCMs have the potential to cause tracking error by limiting USO’s investments, including its ability to fully invest in the Benchmark Oil Futures Contract and other Oil Futures Contracts, which means that the changes in the price of USO’s shares could substantially vary from changes in the price of the Benchmark Oil Futures Contract.

USO’s FCMs have discretion to impose limits on the positions that USO may hold in the Benchmark Oil Futures Contract as well as certain other months. USO’s FCMs have in the past imposed, and may in the future impose, limits on the positions that USO may hold in the Benchmark Oil Futures Contract as well as certain other months that constrain USO’s ability to invest in the Benchmark Oil Futures Contract and other Oil Futures Contracts. For example, in the Spring of 2020, RBC Capital Markets, LLC (“RBC”) expressly informed USO that USO could not hold positions in the June Benchmark Oil Futures Contract expiring on May 19, 2020. At the time RBC imposed this restriction, RBC continued to trade and clear other Oil Futures Contracts for USO, including in connection with rolls and rebalances of its portfolio. At that time, RBC advised USO that, going forward, USO may only purchase additional Benchmark Oil Futures Contracts and other Oil Futures Contracts through RBC for rolls and rebalances of USO’s portfolio and not as investments for the proceeds of new Creation Baskets. The limits imposed by RBC on holdings in USO’s portfolio applied regardless of whether the Oil Futures Contracts purchased would be within the accountability levels and position limits permitted by NYMEX and ICE. Since then, RBC allowed USO to resume purchasing Oil Futures Contracts, including the Benchmark Oil Futures Contract, for investment of the proceeds from Creation Baskets.

Since 2020, USO has entered into agreements with additional FCMs, none of which have precluded USO from purchasing, holding, or reinvesting the proceeds from the purchases of Creation Baskets in Oil Futures Contracts, including the Benchmark Oil Futures Contract. However, limits could be imposed by any of USO’s FCMs that limit USO’s ability to have a substantial portion of its assets invested in the Benchmark Oil Futures Contract. USO cannot predict with any certainty whether, or to what extent, any limitations may be imposed on USO by any FCM in the future.

In addition, when offering Creation Baskets for purchase, limitations imposed by exchanges and/or any of USO’s FCMs could limit USO’s ability to invest the proceeds of the purchases of Creation Baskets in Benchmark Oil Futures Contracts and other Oil Futures Contracts. If this were the case, USO may invest in other permitted investments, including Other Oil-Related Investments, and may hold larger amounts of Treasuries, cash and cash equivalents, which could impair USO’s ability to meet its investment objective.

Tax Risk

An investor’s tax liability may exceed the amount of distributions, if any, on its shares.

Cash or property will be distributed at the sole discretion of USCF. USCF has not and does not currently intend to make cash or other distributions with respect to shares. Investors will be required to pay U.S. federal income tax and, in some cases, state, local, or non-U.S.income tax, on their allocable share of USO’s taxable income, without regard to whether they receive distributions or the amount or value of any such distributions. Therefore, the tax liability of an investor with respect to its shares may exceed the amount of cash or value of property (if any) distributed with respect to such shares.

An investor’s allocable share of taxable income or loss may differ from its economic income or loss on the shares.

Due to the application of the assumptions and conventions applied by USO in making allocations for U.S. federal income tax purposes and other factors, an investor’s allocable share of USO’s income, gain, deduction, loss, or credit may be different than its economic profit or loss from the shares for a taxable year. This difference could be temporary or permanent and, if permanent, may subject an investor to tax on amounts in excess of its economic income.

Items of income, gain, deduction, loss and credit with respect to shares could be reallocated, for U.S. federal income tax purposes, and USO could be liable for U.S. federal income tax, if the IRS does not accept the assumptions and conventions applied by USO in allocating those items, with potential adverse consequences for an investor.

USO applies certain assumptions and conventions in an attempt to comply with the intent of the applicable rules and to report taxable income, gains, deductions, losses and credits in a manner that properly reflects shareholders’ economic gains and losses. It is possible that the IRS could successfully challenge the application by USO of these assumptions and conventions as not fully complying with all aspects of the Internal Revenue Code of 1986, as amended (the “Code”), and applicable U.S. Treasury Regulations, which would require USO to reallocate items of income, gain, deduction, loss or credit in a manner that adversely affects investors. If this occurs, investors may be required to file an amended U.S. federal income tax return and to pay additional taxes, plus deficiency interest, and may be subject to penalties.

Table of Contents

USO may be liable for U.S. federal income tax on any “imputed underpayment” of tax resulting from an adjustment as a result of an IRS audit. The amount of the imputed underpayment generally includes increases in allocations of items of income or gain to any investor and decreases in allocations of items of deduction, loss, or credit to any investor without any offset for any corresponding reductions in allocations of items of income or gain to any investor or increases in allocations of items of deduction, loss, or credit to any investor. If USO is required to pay any U.S. federal income taxes on any imputed underpayment, the resulting tax liability would reduce the net assets of USO and would likely have an adverse impact on the value of the shares. Under certain circumstances, USO may be eligible to make an election to cause the investors to take into account the amount of any imputed underpayment, including any associated interest and penalties. The ability of a publicly traded partnership such as USO to elect this treatment is uncertain. If the election is made, USO would be required to provide investors who owned beneficial interests in the shares in the year to which the adjusted allocations relate with a statement setting forth their proportionate shares of the adjustment (“Adjusted K-1s”). The investors would be required to take the adjustment into account in the taxable year in which the Adjusted K-1s are issued.

USO could be treated as a corporation for U.S. federal income tax purposes, which may substantially reduce the value of the shares.

USO has received an opinion of counsel that, under current U.S. federal income tax laws, USO will be treated as a partnership that is not taxable as a corporation for U.S. federal income tax purposes, provided that (i) at least 90 percent of USO’s annual gross income will be derived from (a) income and gains from commodities (not held as inventory) or futures, forwards, options, swaps and other notional principal contracts with respect to commodities, and (b) interest income (“qualifying income”); (ii) USO is organized and operated in accordance with its governing agreements and applicable law; and (iii) USO does not elect to be taxed as a corporation for U.S. federal income tax purposes. Although USCF anticipates that USO has satisfied and will continue to satisfy the “qualifying income” requirement for all of its taxable years, that result cannot be assured. USO has not requested and will not request any ruling from the IRS with respect to its classification as a partnership for U.S. federal income tax purposes. If the IRS were to successfully assert that USO is taxable as a corporation for U.S. federal income tax purposes in any taxable year, rather than passing through its income, gains, losses, deductions, and credits proportionately to its shareholders, USO would be subject to U.S. federal income tax imposed at the applicable corporate rates on its net income for the year. In addition, although USCF does not currently intend to make distributions with respect to USO shares, if USO were treated as a corporation for U.S. federal income tax purposes, any distributions made with respect to USO shares would be taxable to shareholders as dividend income to the extent of USO’s current and accumulated earnings and profits. Taxation of USO as a corporation could materially reduce the after-tax return on an investment in shares and could substantially reduce the value of the shares.

USO is organized and operated as a limited partnership in accordance with the provisions of the LP Agreement and applicable state law, and therefore, USO has a more complex tax treatment than traditional mutual funds.

USO is organized and operated as a limited partnership in accordance with the provisions of the LP Agreement and applicable state law, and is treated as a partnership for U.S. federal income tax purposes. No U.S. federal income tax is paid by USO on its income. Instead, USO will furnish shareholders each year with tax information on IRS Schedules K-1 and/or K-3 (Form 1065), as applicable, and each U.S. shareholder is required to report on its U.S. federal income tax return its allocable share of the income, gain, loss, deduction, and credit of USO.

These amounts must be reported without regard to the amount of cash or value of property the shareholder receives (if any) as a distribution from USO during the taxable year. A shareholder, therefore, may be allocated income or gain by USO but receive no cash distribution with which to pay the tax liability resulting from the allocation, or may receive a distribution that is insufficient to pay such liability.

In addition to U.S. federal income taxes, shareholders may be subject to other taxes, such as state and local income taxes, unincorporated business taxes, business franchise taxes and estate, inheritance or intangible taxes that may be imposed by the various jurisdictions in which USO does business or owns property or where the shareholders reside. Although an analysis of those various taxes is not presented here, each prospective shareholder should consider their potential impact on its investment in USO. It is each shareholder’s responsibility to file the appropriate U.S. federal, state, local and non-U.S.tax returns.

Table of Contents

If USO is required to withhold tax with respect to any non-U.S. shareholders, the cost of such withholding may be borne by all shareholders.

Under certain circumstances, USO may be required to pay withholding tax with respect to allocations to non-U.S. shareholders. Although the LP Agreement provides that any such withholding will be treated as being distributed to the non-U.S. shareholder, USO may not be able to cause the economic cost of such withholding to be borne by the non-U.S. shareholder on whose behalf such amounts were withheld since it does not generally expect to make any distributions. Under such circumstances, the economic cost of the withholding may be borne by all shareholders, not just the shareholders on whose behalf such amounts were withheld. This could have a material impact on the value of the shares.

The impact of changes in U.S. federal income tax laws on USO is uncertain.

In general, legislative or other actions relating to U.S. federal income taxes could have a negative effect on USO or its investors. Matters pertaining to U.S. federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Treasury Department. The Trump Administration has proposed significant changes to the Code and existing U.S federal income tax regulations and there are a number of proposals in Congress that, if enacted, would similarly modify the Code. The likelihood of any such legislation being enacted is uncertain, but new legislation and any U.S. Treasury regulations, administrative interpretations or court decisions interpreting such legislation could result in adverse tax consequences to USO and its investors. Investors are urged to consult with their tax advisor with respect to the status of legislative, regulatory or administrative developments and proposals and their potential effect on an investment in shares of USO.

OTC Contract Risk

USO will be subject to credit risk with respect to counterparties to OTC contracts entered into by USO.

USO faces the risk of non-performance by counterparties to its OTC contracts. Unlike in futures contracts, the counterparty to OTC contracts is generally a single bank or other financial institution, rather than a clearing organization backed by a group of financial institutions. As a result, there will be greater counterparty credit risk in these transactions. A counterparty may not be able to meet its obligations to USO, in which case USO could suffer significant losses on these contracts. The two-way margining requirements imposed by U.S. regulators, discussed in “Item 1. Business – Commodities Regulation,” are intended to mitigate this risk.

If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, USO may experience significant delays in obtaining recovery in a bankruptcy or other reorganization proceeding. USO may obtain only limited recovery or may obtain no recovery in such circumstances.

USO mitigates these risks by typically entering into transactions only with major global financial institutions.

Valuing OTC derivatives may be less certain than valuing exchange-traded and/or cleared financial instruments.

In general, valuing OTC derivatives is less certain than valuing actively traded financial instruments such as exchange traded futures contracts and securities or cleared swaps because, for OTC derivatives, the price and terms on which such OTC derivatives are entered into or can be terminated are individually negotiated, and those prices and terms may not reflect the best price or terms available from other sources. In addition, while market makers and dealers generally quote indicative prices or terms for entering into or terminating OTC contracts, they typically are not contractually obligated to do so, particularly if they are not a party to the transaction. As a result, it may be difficult to obtain an independent value for an outstanding OTC derivatives transaction.

USO’s rights under an OTC contract may be restricted by regulations.

Regulations adopted by global prudential regulators that are now in effect require certain prudentially regulated entities and certain of their affiliates and subsidiaries (including swap dealers) to include in their derivatives contracts and certain other financial contracts terms that delay or restrict the rights of counterparties (such as USO) to terminate such contracts, foreclose upon collateral, exercise other default rights or restrict transfers of credit support in the event that the prudentially regulated entity and/or its affiliates are subject to certain types of resolution or insolvency proceedings. Similar regulations and laws have been adopted in non-U.S. jurisdictions that may apply to USO’s counterparties located in those jurisdictions. These requirements could adversely affect USO’s ability to terminate existing derivatives contracts, exercise default rights, or satisfy obligations owed to it with collateral received under such contracts if USO’s counterparty and/or its affiliates is subject to resolution or insolvency proceedings.

Table of Contents

The use of swap agreements may expose USO to early termination risk, which could result in significant losses to USO.

Swap agreements do not have uniform terms. A swap counterparty may have the right to close out USO’s position due to the occurrence of certain events (for example, if USO defaults on certain terms of the swap agreement, or if there is a material decline in USO’s NAV on a particular day) and request immediate payment of amounts owed by USO under the agreement. If the level of USO’s NAV has a dramatic intraday move, the terms of the swap agreement may permit the counterparty to close out a transaction with USO at a price calculated by the counterparty that, in good faith, represents such counterparty’s loss, but such loss may not represent fair market value.

Other Risks

USO is not leveraged, but it could become leveraged if it had insufficient assets to completely meet its margin or collateral requirements relating to its investments.

Although permitted to do so under its LP Agreement, USO has not leveraged, and does not intend to leverage, its assets through borrowings or otherwise, and USO makes its investments accordingly. Consistent with the foregoing, USO’s investments will take into account the need for USO to maintain adequate liquidity to meet its margin and collateral requirements and to avoid, to the extent reasonably possible, USO becoming leveraged. If market conditions require it, USO may implement risk reduction procedures, which may include changes to USO’s investments, and such changes may occur on short notice.

USO does not and will not borrow money or use debt to satisfy its margin or collateral obligations in respect of its investments, but it could become leveraged if USO were to hold insufficient assets that would allow it to meet not only the current, but also future, margin or collateral obligations required for such investments. Such a circumstance could occur if USO were to hold assets that have a value of less than zero.

USCF endeavors to have the value of USO’s Treasuries, cash and cash equivalents, whether held by USO or posted as margin or other collateral, at all times approximate the aggregate market value of its obligations under its Oil Futures Contracts and Other Oil-Related Investments.

USO may temporarily limit the offering of Creation Baskets.

USO may determine to limit the issuance of its shares through the offering of Creation Baskets to its Authorized Participants in order to allow it to reinvest the proceeds from sales of its Creation Baskets in currently permitted assets in a manner that meets its investment objective. USO will announce to the market through the filing of a Current Report on Form 8-K if it intends to limit the offering of Creation Baskets at any time. In such case, orders for Creation Baskets will be considered for acceptance in the order they are received by USO and USO would continue to accept requests for redemption of its shares from Authorized Participants through Redemption Baskets during the period of the limited offering of Creation Baskets.

Certain of USO’s investments could be illiquid, which could cause large losses to investors at any time or from time to time.

Futures positions cannot always be liquidated at the desired price. It is difficult to execute a trade at a specific price when there is a relatively small volume of buy and sell orders in a market. A market disruption, such as a war or a foreign government taking political actions that disrupt the market for its currency, its crude oil production or exports, or another major export, can also make it difficult to liquidate a position. Because both Oil Futures Contracts and Other Oil-Related Investments may be illiquid, USO’s Oil Interests may be more difficult to liquidate at favorable prices in periods of illiquid markets and losses may be incurred during the period in which positions are being liquidated. The large size of the positions that USO may acquire increases the risk of illiquidity both by making its positions more difficult to liquidate and by potentially increasing losses while trying to do so.

OTC contracts that are not subject to clearing may be even less marketable than futures contracts because they are not traded on an exchange, do not have uniform terms and conditions, and are entered into based upon the creditworthiness of the parties and the availability of credit support, such as collateral, and in general, they are not transferable without the consent of the counterparty. These conditions make such contracts less liquid than standardized futures contracts traded on an exchange and could adversely impact USO’s ability to realize the full value of such contracts. In addition, even if collateral is used to reduce counterparty credit risk, sudden changes in the value of OTC transactions may leave a party open to financial risk due to a counterparty default since the collateral held may not cover a party’s exposure on the transaction in such situations.

Table of Contents

USO is not actively managed and its investment objective is to track the Benchmark Oil Futures Contract so that the average daily percentage change in USO’s NAV for any period of 30 successive valuation days will be within plus/minus ten percent (10%) of the average daily percentage change in the price of the Benchmark Oil Futures Contract over the same period.

USO is not actively managed by conventional methods. Accordingly, if USO’s investments in Oil Interests are declining in value, in the ordinary course, USO will not close out such positions except in connection with paying the proceeds to an Authorized Participant upon the redemption of a basket or closing out its positions in Oil Futures Contracts and other permitted investments (i) in connection with the monthly change in the Benchmark Oil Futures Contract; (ii) when USO otherwise determines it would be appropriate to do so, e.g., due to regulatory requirements or risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants); or (iii) to avoid USO becoming leveraged, and it reinvests the proceeds in new Oil Futures Contracts or Other Oil-Related Investments to the extent possible. USCF will seek to cause the NAV of USO’s shares to track the Benchmark Oil Futures Contract during periods in which its price is flat or declining as well as when the price is rising.

USO has always had the ability to invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract and in Other Oil-Related Investments, such as OTC swaps. USO may invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract, and/or Other Oil-Related Investments, and/or USO may need to hold significant portions of its portfolio in cash beyond what it has historically held for reasons including (but not limited to) the need to address the changes in market conditions, regulatory requirements or risk mitigation measures (including those that may be taken by market participants generally including USO), or the need to satisfy potential margin requirements. USO’s ability to invest in the Benchmark Oil Futures Contract and/or Other Oil-Related Investments, could be limited as a result of any or all of the above reasons.

USO may not meet the listing standards of NYSE Arca, which would adversely impact an investor’s ability to sell shares.

USO’s shares are listed for trading on the NYSE Arca under the market symbol “USO.” NYSE Arca may suspend USO’s shares from trading on the exchange with or without prior notice to USO, upon failure of USO to comply with the NYSE’s listing requirements, or when in its sole discretion, the NYSE Arca determines that such suspension of dealings is in the public interest or otherwise warranted. There can be no assurance that the requirements necessary to maintain the listing of USO’s shares will continue to be met or will remain unchanged. If USO were unable to meet the NYSE’s listing standards and were to become delisted, an investor’s ability to sell its shares would be adversely impacted.

The NYSE Arca may halt trading in USO’s shares, which would adversely impact an investor’s ability to sell shares.

Trading in shares may be halted due to market conditions or, in light of NYSE Arca rules and procedures, for reasons that, in the view of the NYSE Arca, make trading in shares inadvisable. In addition, trading is subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules that require trading to be halted for a specified period based on a specified market decline.

The liquidity of USO’s shares may also be affected by the withdrawal from participation of Authorized Participants, which could adversely affect the market price of the shares.

In the event that one or more Authorized Participants which have substantial interests in the shares withdraw from participation, the liquidity of USO’s shares will likely decrease, which could adversely affect the market price of the shares and result in investors incurring a loss on their investment.

Shareholders that are not Authorized Participants may only purchase or sell their shares in secondary trading markets, and the conditions associated with trading in secondary markets may adversely affect investors’ investment in the shares.

Only Authorized Participants may directly purchase shares from or redeem shares with, USO through Creation Baskets or Redemption Baskets, respectively. All other investors that desire to purchase or sell shares must do so through the NYSE Arca or in other markets, if any, in which the shares may be traded. Shares may trade at a premium or discount relative to NAV per share.

The lack of an active trading market for USO’s shares may result in losses on an investor’s investment in USO at the time the investor sells the shares.

Although USO’s shares are listed and traded on the NYSE Arca, there can be no guarantee that an active trading market for the shares will be maintained. If an investor needs to sell shares at a time when no active trading market for them exists, the price the investor receives upon sale of the shares, assuming they were able to be sold, likely would be lower than if an active market existed.

Limited partners and shareholders do not participate in the management of USO and do not control USCF, so they do not have any influence over basic matters that affect USO.

The limited partners and shareholders take no part in the management or control, and have a minimal voice in USO’s operations or business. Limited partners and shareholders must therefore rely upon the duties and judgment of USCF to manage USO’s affairs. Limited partners and shareholders have no right to elect USCF on an annual or any other continuing basis. If USCF voluntarily withdraws, however, the holders of a majority of USO’s outstanding shares (excluding for purposes of such determination shares owned, if any, by the withdrawing general partner and its affiliates) may elect its successor. USCF may not be removed as general partner except upon approval by the affirmative vote of the holders of at least 66 2/3 percent of USO’s outstanding shares (excluding shares, if any, owned by USCF and its affiliates), subject to the satisfaction of certain conditions set forth in the LP Agreement.

Limited partners may have limited liability in certain circumstances, including potentially having liability for the return of wrongful distributions.

Under Delaware law, a limited partner might be held liable for USO’s obligations as if it were a general partner if the limited partner participates in the control of the partnership’s business and the persons who transact business with the partnership think the limited partner is the general partner.

A limited partner will not be liable for assessments in addition to its initial capital investment in any of USO’s shares. However, a limited partner may be required to repay to USO any amounts wrongfully returned or distributed to it under some circumstances. Under Delaware law, USO may not make a distribution to limited partners if the distribution causes USO’s liabilities (other than liabilities to partners on account of their partnership interests and nonrecourse liabilities) to exceed the fair value of USO’s assets. Delaware law provides that a limited partner who receives such a distribution and knew at the time of the distribution that the distribution violated the law will be liable to the limited partnership for the amount of the distribution for three years from the date of the distribution.

USCF’s LLC Agreement provides limited authority to the Non-Management Directors, and any Director of USCF may be removed by USCF’s parent company, which is wholly owned by The Marygold Companies, Inc., a controlled public company where the majority of shares are owned by Nicholas D. Gerber along with certain of his family members and certain other shareholders.

USCF’s Board of Directors currently consists of four Management Directors, who are also executive officers or employees of USCF, and three Non-Management Directors, who are considered independent for purposes of applicable NYSE Arca and SEC rules. Under USCF’s LLC Agreement, the Non-Management Directors have only such authority as the Management Directors expressly confer upon them, which means that the Non-Management Directors may have less authority to control the actions of the Management Directors than is typically the case with the independent members of a company’s Board of Directors. In addition, any Director may be removed by written consent of USCF Investments, Inc. (“USCF Investments”), formerly Wainwright Holdings, Inc., which is the sole member of USCF. The sole shareholder of USCF Investments is The Marygold Companies, Inc., formerly Concierge Technologies, Inc. (“Marygold”), a company publicly traded under the ticker symbol “MGLD.” Mr. Nicholas D. Gerber, along with certain of his family members and certain other shareholders, owns the majority of the shares in Marygold, which is the sole shareholder of USCF Investments, the sole member of USCF. Accordingly, although USCF is governed by the USCF Board of Directors, which consists of both Management Directors and Non-Management Directors, pursuant to the LLC Agreement, it is possible for Mr. Gerber to exercise his indirect control of USCF Investments to effect the removal of any Director (including the Non-Management Directors which comprise the Audit Committee) and to replace that Director with another Director. Having control in one person could have a negative impact on USCF and USO, including their regulatory obligations.

There is a risk that USO will not earn trading gains sufficient to compensate for the fees and expenses that it must pay and as such USO may not earn any profit.

USO pays brokerage charges of approximately 0.10% of average total net assets based on brokerage fees of $3.50 per buy or sell, management fees of 0.45% of NAV on its average net assets, and OTC spreads and extraordinary expenses (e.g., subsequent offering expenses, other expenses not in the ordinary course of business, including the indemnification of any person against liabilities and obligations to the extent permitted by law and required under the LP Agreement and under agreements entered into by USCF on USO’s behalf and the bringing and defending of actions at law or in equity and otherwise engaging in the conduct of litigation and the incurring of legal expenses and the settlement of claims and litigation) that cannot be quantified.

These fees and expenses must be paid in all cases regardless of whether USO’s activities are profitable. Accordingly, USO must earn trading gains sufficient to compensate for these fees and expenses before it can earn any profit.

Table of Contents

USO is subject to extensive regulatory reporting and compliance.

USO is subject to a comprehensive scheme of regulation under the federal commodities and securities laws. USO could be subject to sanctions for a failure to comply with those requirements, which could adversely affect its financial performance (in the case of financial penalties) or ability to pursue its investment objective (in the case of a limitation on its ability to trade).

Because USO’s shares are publicly traded, USO is subject to certain rules and regulations of federal, state and financial market exchange entities charged with the protection of investors and the oversight of companies whose securities are publicly traded. These entities include the Public Company Accounting Oversight Board (the “PCAOB”), the SEC, the CFTC, the NFA, and NYSE Arca and these authorities have continued to develop additional regulations or interpretations of existing regulations. USO’s ongoing efforts to comply with these regulations and interpretations have resulted in, and in the future, may result in, a diversion of management’s time and attention from revenue-generating activities to compliance related activities.

USO is responsible for establishing and maintaining adequate internal control over financial reporting. USO’s internal control system is designed to provide reasonable assurance to its management regarding the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective may provide only reasonable assurance with respect to financial statement preparation and presentation.

Regulatory changes or actions, including the implementation of new legislation are impossible to predict but may significantly and adversely affect USO.

The futures markets are subject to comprehensive statutes, regulations, and margin requirements. Such statutes, regulations and requirements are subject to ongoing modification by governmental and judicial action. This is particularly so whenever there is a change in presidential administration, which can lead to changes in regulatory priorities and policy. The effect of any future regulatory change on USO is impossible to predict, but it could be substantial and adverse. In addition, the CFTC SEC, futures exchanges, and other entities are authorized to take extraordinary actions in the event of a market emergency including, for example, the retroactive implementation of speculative position limits or higher margin requirements, the establishment of daily price limits and the suspension of trading. For a more detailed discussion of the regulations to be imposed by the CFTC and the SEC and the potential impacts thereof on USO, please see “Item 1. Business - Commodities Regulation” in this annual report on Form 10-K.

USO is not a registered investment company so shareholders do not have the protections of the 1940 Act.

USO is not an investment company subject to the 1940 Act. Accordingly, investors do not have the protections afforded by that statute, which, for example, requires investment companies to have a majority of disinterested directors and regulates the relationship between the investment company and its investment manager.

Trading in international markets could expose USO to credit and regulatory risk.

USO invests primarily in Oil Futures Contracts, a significant portion of which are traded on United States exchanges, including the NYMEX. However, a portion of USO’s trades may take place on markets and exchanges outside the United States. Trading on such non-U.S. markets or exchanges presents risks because they are not subject to the same degree of regulation as their U.S. counterparts, including potentially different or diminished investor protections. In trading contracts denominated in currencies other than U.S. dollars, USO is subject to the risk of adverse exchange-rate movements between the U.S. dollar and the functional currencies of such contracts. Additionally, trading on non-U.S. exchanges is subject to the risks presented by exchange controls, expropriation, increased tax burdens and exposure to local economic declines and political instability. An adverse development with respect to any of these variables could reduce the profit or increase the loss earned on trades in the affected international markets.

USO and USCF may have conflicts of interest, which may permit them to favor their own interests to the detriment of shareholders.

USO is subject to actual and potential inherent conflicts involving USCF, various commodity futures brokers and Authorized Participants. USCF’s officers, directors and employees do not devote their time exclusively to USO and also are directors, officers or employees of other entities that may compete with USO for their services. They could have a conflict between their responsibilities to USO and to those other entities. As a result of these and other relationships, parties involved with USO have a financial incentive to act in a manner other than in the best interests of USO and the shareholders. USCF has not established any formal procedure to resolve conflicts of interest. Consequently, investors are dependent on the good faith of the respective parties subject to such conflicts of interest to resolve them equitably. Although USCF attempts to monitor these conflicts, it is extremely difficult, if not impossible, for USCF to ensure that these conflicts do not, in fact, result in adverse consequences to the shareholders.

Table of Contents

USCF serves as the general partner or sponsor to each of USO and the Related Public Funds. USCF may have a conflict to the extent that its trading decisions for USO may be influenced by the effect they would have on the other funds it manages. By way of example, if, as a result of reaching position limits imposed by the NYMEX, USO purchased oil futures contracts, this decision could impact USO’s ability to purchase additional oil futures contracts if the number of contracts held by funds managed by USCF reached the maximum allowed by the NYMEX. Similar situations could adversely affect the ability of the Related Public Funds to track their benchmark futures contract(s).

USO may also be subject to certain conflicts with respect to its FCMs, including, but not limited to, conflicts that result from the FCM receiving greater amounts of compensation from other clients, or purchasing opposite or competing positions on behalf of third-party accounts traded through the FCMs. In addition, USCF’s principals, officers, directors or employees may trade futures and related contracts for their own account. A conflict of interest may exist if their trades are in the same markets and at the same time as USO trades using the clearing broker to be used by USO. A potential conflict also may occur if USCF’s principals, officers, directors or employees trade their accounts more aggressively or take positions in their accounts which are opposite, or ahead of, the positions taken by USO.

USO could terminate at any time and cause the liquidation and potential loss of an investor’s investment and could upset the overall maturity and timing of an investor’s investment portfolio.

USO may terminate at any time, regardless of whether USO has incurred losses, subject to the terms of the LP Agreement. In particular, unforeseen circumstances, including, but not limited to, (i) market conditions, regulatory requirements, risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants) that would lead USO to determine that it could no longer foreseeably meet its investment objective or that USO’s aggregate net assets in relation to its operating expenses or its margin or collateral requirements make the continued operation of USO unreasonable or imprudent, or (ii) adjudication of incompetence, bankruptcy, dissolution, withdrawal, or removal of USCF as the general partner of USO could cause USO, to terminate unless a majority interest of the limited partners within 90 days of the event elects to continue the partnership and appoints a successor general partner, or the affirmative vote of a majority in interest of the limited partners subject to certain conditions. However, no level of losses will require USCF to terminate USO. USO’s termination would cause the liquidation and potential loss of an investor’s investment. Termination could also negatively affect the overall maturity and timing of an investor’s investment portfolio.

USO does not expect to make cash distributions.

USO has not previously made any cash distributions and intends to reinvest any realized gains in additional Oil Interests rather than distributing cash to limited partners, or other shareholders. Therefore, unlike mutual funds, commodity pools or other investment pools that actively manage their investments in an attempt to realize income and gains from their investing activities and distribute such income and gains to their investors, USO generally does not expect to distribute cash to limited partners. An investor should not invest in USO if the investor will need cash distributions from USO to pay taxes on its share of income and gains of USO, if any, or for any other reason. Nonetheless, although USO does not intend to make cash distributions, the income earned from its investments held directly or posted as margin may reach levels that merit distribution, e.g., at levels where such income is not necessary to support its underlying investments in Oil Interests and investors adversely react to being taxed on such income without receiving distributions that could be used to pay such tax. If this income becomes significant then cash distributions may be made.

An unanticipated number of Redemption Basket requests during a short period of time could have an adverse effect on USO’s NAV.

If a substantial number of requests for redemption of Redemption Baskets are received by USO during a relatively short period of time, USO may not be able to satisfy the requests from USO’s assets not committed to trading. As a consequence, it could be necessary to liquidate positions in USO’s trading positions before the time that the trading strategies would otherwise dictate liquidation.

Table of Contents

The suspension in the ability of Authorized Participants to purchase Creation Baskets could cause USO’s NAV to differ materially from its trading price.

In the event that there was a suspension in the ability of Authorized Participants to purchase additional Creation Baskets, Authorized Participants and other groups that make a market in shares of USO would likely still continue to actively trade the shares. However, in such a situation, Authorized Participants and other market makers may seek to adjust the market they make in the shares. Specifically, such market participants may increase the spread between the prices that they quote for offers to buy and sell shares to allow them to adjust to the potential uncertainty as to when they might be able to purchase additional Creation Baskets of shares. In addition, Authorized Participants may be less willing to offer to quote offers to buy or sell shares in large numbers. The potential impact of either wider spreads between bid and offer prices, or reduced number of shares on which quotes may be available, could increase the trading costs to investors in USO compared to the quotes and the number of shares on which bids and offers are made if the Authorized Participants still were able to freely create new baskets of shares. In addition, there could be a significant variation between an the market price at which shares are traded and the shares’ NAV, which is also the price at which shares can be redeemed with USO by Authorized Participants in Redemption Baskets. The foregoing could also create significant deviations from USO’s investment objective. Any potential impact to the market for shares of USO that could occur from Authorized Participant’s inability to create new baskets would likely not extend beyond the time when USO resumes selling Creation Baskets.

For example, USO suspended purchases of Creation Baskets in April 2020 as a result of the exhaustion of available SEC registered shares that could be issued by USO due to unexpected demand during the aforementioned market volatility arising from the COVID-19 pandemic, related supply chain disruptions, war and disputes among oil-producing countries. This resulted in the market price of USO shares on April 21, 2020 trading at 36% higher than USO’s reported end-of-day per share NAV. The high premium that occurred in the Spring of 2020 was short-lived and fell almost immediately, notwithstanding the suspension of sales of Creation Baskets. On April 22, 2020, the market price of USO shares fell to a level of 8.66% above the per share NAV, and, from April 23, 2020, continued its decline to 1.45% on May 1, 2020. For the period beginning May 1, 2020 and ending May 29, 2020 the premium averaged 2.25%, and for the period from beginning June 30, 2020 through December 31, 2020, the premium averaged -0.14%. Investors should be aware that high premiums such as those that occurred in April 2020 can be transitory. Any potential premium or impact to the market in shares of USO that could occur from the Authorized Participants’ inability to purchase new Creation Baskets would likely not extend beyond the time when USO resumes selling Creation Baskets.

USO may determine that, to allow it to reinvest the proceeds from sales of its Creation Baskets in currently permitted assets in a manner that meets its investment objective, it may limit or suspend its offers of Creation Baskets.

USO may determine to limit the issuance of its shares through the offering of Creation Baskets to its Authorized Participants. As a result of certain circumstances described herein, including (1) the need to comply with regulatory requirements (including, but not limited to, exchange accountability levels and position limits as well as statutory or regulatory limits); (2) market conditions (including but not limited to those allowing USO to obtain greater liquidity or to execute transactions with more favorable pricing); and (3) risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants) that limit USO and other market participants from investing in particular crude oil futures contracts, USO’s management may determine that it will limit the issuance of shares and the offerings of Creation Baskets because it is unable to invest the proceeds from such offerings in investments that would permit it to reasonably meet its investment objective.

If such a determination is made, the same consequences associated with a suspension of the offering of Creation Baskets, as described in the foregoing risk factor, “The suspension in the ability of Authorized Participants to purchase Creation Baskets could cause USO’s NAV to differ materially from its trading price,” could also occur as a result of USO determining to limit the offering of Creation Baskets.

Table of Contents

USO may be subject to interest rate risk, which may prevent USO from investing fully at prevailing rates until any current investments in Treasuries mature in order to avoid selling those investments at a loss.

Interest rate risk is the risk that fixed income securities and other investments in USO’s portfolio will fluctuate in value because of a change in interest rates. Interest rate changes can be sudden and unpredictable, and USO may lose money because of movements in interest rates. When interest rates rise, the value of fixed income securities typically falls. In a rising interest rate environment, USO may not be able to fully invest at prevailing rates until any current investments in Treasuries mature in order to avoid selling those investments at a loss. Interest rate risk is generally lower for shorter term investments and higher for longer term investments. In addition, in rising interest rate environments, it is possible that the Treasuries held by USO will decline in value. When interest rates fall, USO may be required to reinvest the proceeds from the sale, redemption or early prepayment of a Treasuries or money market security at a lower interest rate.

As inflation increases, the present value of USO’s assets may decline.

Inflation is a general increase in the overall price level of goods and services in the economy. The United States Federal Reserve has a stated goal of maintaining a two percent increase in inflation over the long run, as measured by the annual change in the price index for personal consumption expenditures.

Following the COVID-19 pandemic, the United States experienced inflation above the Federal Reserve’s stated two percent goal. Other world economies similarly experienced elevated inflation rates. The Federal Reserve increased interest rates and successfully reduced inflation so that it is close to the stated two percent goal. As a result, in 2024, the Federal Reserve began reducing interest rates. However, the rate of inflation in the United States is still above the stated two percent goal. Inflation has the effect of eroding the value of cash or bonds. In a high inflation environment, the value of USO’s cash and Treasury investments may decline.

USO may potentially lose money by investing in government money market funds.

USO invests in government money market funds. Although such government money market funds seek to preserve the value of an investment at $1.00 per share, there is no guarantee that they will be able to do so and USO may lose money by investing in a government money market fund. An investment in a government money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation (the “FDIC”), or any other government agency. The share price of a government money market fund can fall below the $1.00 share price. USO cannot rely on or expect a government money market fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the government money market fund’s $1.00 share price. The credit quality of a government money market fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the government money market fund’s share price. Due to fluctuations in interest rates, the market value of securities held by a government money market fund may vary. A government money market fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets.

The failure or bankruptcy of a clearing broker could result in a substantial loss of USO’s assets and could impair USO in its ability to execute trades.

The CEA and CFTC regulations impose several requirements on FCMs and clearing houses that are designed to protect customers, including mandating the implementation of risk management programs, internal monitoring and controls, capital and liquidity standards, customer disclosures, and auditing and examination programs. In particular, the CEA and CFTC regulations require FCMs and clearing houses to segregate all funds received from customers from proprietary assets. There can be no assurance that the requirements imposed by the CEA and CFTC regulations will prevent losses to, or not materially adversely affect, USO or its investors.

In particular, in the event of an FCM’s or clearing house’s bankruptcy, USO could be limited to recovering either a pro rata share of all available funds segregated on behalf of the FCM’s combined customer accounts or USO may not recover any assets at all. USO may also incur a loss of any unrealized profits on its open and closed positions. This is because if such a bankruptcy were to occur, USO would be afforded the protections granted to customers of an FCM, and participants to transactions cleared through a clearing house, under the United States Bankruptcy Code and applicable CFTC regulations. Such provisions generally provide for a pro rata distribution to customers of customer property held by the bankrupt FCM or an Exchange’s clearing house if the customer property held by the FCM or the Exchange’s clearing house is insufficient to satisfy all customer claims.

Table of Contents

Bankruptcy of a clearing FCM can be caused by, among other things, the default of one of the FCM’s customers. In this event, the Exchange’s clearing house is permitted to use the entire amount of margin posted by USO (as well as margin posted by other customers of the FCM) to cover the amounts owed by the bankrupt FCM. Consequently, USO could be unable to recover amounts due to it on its futures positions, including assets posted as margin, and could sustain substantial losses.

Notwithstanding that USO could sustain losses upon the failure or bankruptcy of its FCM, the majority of USO’s assets are held in Treasuries, cash and/or cash equivalents with USO’s Custodian and would not be impacted by the bankruptcy of an FCM.

The failure or bankruptcy of USO’s Custodian could result in a substantial loss of USO’s assets.

The majority of USO’s assets are held in Treasuries, cash and/or cash equivalents with the Custodian. The insolvency of the Custodian could result in a complete loss of USO’s assets held by that Custodian, which, at any given time, would likely comprise a substantial portion of USO’s total assets.

Competing claims of intellectual property rights may adversely affect USO and an investment in USO’s shares.

USCF believes that it has properly licensed or obtained the appropriate consent of all necessary parties with respect to intellectual property rights. However, other third parties could allege ownership as to such rights and may bring legal action asserting their claims. The expenses in litigating, negotiating, cross-licensing or otherwise settling such claims may adversely affect USO. Additionally, as a result of such action, USO could potentially change its investment objective, strategies or benchmark. Each of these factors could have a negative impact on the performance of USO.

Due to the increased use of technologies, intentional and unintentional cyber-attacks pose operational and information security risks.

With the increased use of technologies such as the Internet and the dependence on computer systems to perform necessary business functions, USO is susceptible to operational and information security risks. In general, cyber incidents can result from deliberate attacks or unintentional events such as a cyber-attack against USO, a natural catastrophe, an industrial accident, failure of USO’s disaster recovery systems, or consequential employee error. Cyber-attacks include, but are not limited to, gaining unauthorized access to digital systems for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyber - attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites. Cyber security failures or breaches of USO’s clearing broker or third party service provider (including, but not limited to, index providers, the administrator and transfer agent, the custodian), have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, the inability of USO shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, and/or additional compliance costs. Adverse effects can become particularly acute if those events affect USO’s electronic data processing, transmission, storage, and retrieval systems, or impact the availability, integrity, or confidentiality of our data.

In addition, a service provider that has experienced a cyber-security incident may divert resources normally devoted to servicing USO to addressing the incident, which would be likely to have an adverse effect on USO’s operations. Cyber-attacks may also cause disruptions to the futures exchanges and clearinghouses through which USO invests in futures contracts, which could result in disruptions to USO’s ability to pursue its investment objective, resulting in financial losses to USO and its shareholders.

In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. USO and its shareholders could be negatively impacted as a result. While USCF and the Related Public Funds, including USO, have established business continuity plans, there are inherent limitations in such plans, including the possibility that certain risks have not been identified or that new risks will emerge before countervailing measures can be implemented. Furthermore, USO cannot control cybersecurity plans and systems of its service providers, market makers or Authorized Participants.

USO’s investment returns could be negatively affected by climate change and greenhouse gas restrictions.

Driven by concern over the risks of climate change, a number of countries have adopted, or are considering the adoption of, regulatory frameworks to reduce greenhouse gas emissions or production and use of oil and gas. These include adoption of cap and trade regimes, carbon taxes, trade tariffs, minimum renewable usage requirements, restrictive permitting, increased efficiency standards, and incentives or mandates for renewable energy. Political and other actors and their agents increasingly seek to advance climate change objectives indirectly, such as by seeking to reduce the availability of or increase the cost for, financial and investment in the oil and gas sector and taking actions intended to promote changes in business strategy for oil and gas companies. Many governments are also providing tax advantages and other subsidies to support transitioning to alternative energy sources or mandating the use of specific fuels other than oil or natural gas. Depending on how policies are formulated and applied, they could have the potential to negatively affect USO’s investment returns and make oil and natural gas products more expensive or less competitive.

USO and USCF are subjects of class action, derivative and other litigation. In light of the inherent uncertainties involved in litigation matters, an adverse outcome in this litigation could materially adversely affect USO’s and USCF’s financial condition.

USO, USCF and USCF’s directors and certain of its officers are currently subject to litigation. Estimating an amount or range of possible losses resulting from litigation proceedings to USO and USCF is inherently difficult and requires an extensive degree of judgment, particularly where the matters involve indeterminate claims for monetary damages and are subject to appeal. In addition, because most legal proceedings are resolved over extended periods of time, potential losses are subject to change due to, among other things, new developments, changes in legal strategy, the outcome of intermediate procedural and substantive rulings and other parties’ settlement posture and their evaluation of the strength or weakness of their case against USO and USCF. For these reasons, we are currently unable to predict the ultimate timing or outcome of, or reasonably estimate the possible losses or a range of possible losses resulting therefrom. In light of the inherent uncertainties involved in such matters, an adverse outcome in this litigation could materially adversely affect USO’s or USCF’s financial condition, results of operations or cash flows in any particular reporting period. In addition, litigation could result in substantial costs and divert USCF’s management’s attention and resources from conducting USCF’s operations, including the management of USO and the Related Public Funds. For more information, see “Item 3. Legal Proceedings” in this annual report on Form 10-K.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion should be read in conjunction with the financial statements and the notes thereto of USO included elsewhere in this annual report on Form 10-K.

Forward-Looking Information

This annual report on Form 10-K, including this “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” contains “forward-looking statements” which generally relate to future events or future performance. In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential” or the negative of these terms or other comparable terminology. All statements (other than statements of historical fact) included in this annual report on Form 10-K that address activities, events or developments that will or may occur in the future, including such matters as changes in inflation in the United States, movements in the stock market, movements in U.S. and foreign currencies, and market volatility in the commodities markets and futures markets and indexes that track such movements, the Russia-Ukraine war and conflicts in the Middle East, USO’s operations, USCF’s plans and references to USO’s future success and other similar matters, are forward-looking statements. These statements are only predictions. Actual events or results may differ materially. These statements are based upon certain assumptions and analyses USCF has made based on its perception of historical trends, current conditions and expected future developments, as well as other factors appropriate in the circumstances. Whether or not actual results and developments will conform to USCF’s expectations and predictions, however, is subject to a number of risks and uncertainties, including the special considerations discussed in this annual report on Form 10-K, general economic, market and business conditions, changes in laws or regulations, including those concerning taxes, made by governmental authorities or regulatory bodies, and other world economic and political developments. Consequently, all the forward-looking statements made in this annual report on Form 10-K are qualified by these cautionary statements, and there can be no assurance that the actual results or developments USCF anticipates will be realized or, even if substantially realized, that they will result in the expected consequences to, or have the expected effects on, USO’s operations or the value of its shares.

USO has based the forward-looking statements included in this annual report on Form 10-K on information available to it on the date of this annual report on Form 10-K, and USO assumes no obligation to update any such forward-looking statements. Although USO undertakes no obligation to revise or update any forward-looking statements, whether as a result of new information, future events or otherwise, investors are advised to consult any additional disclosures that USO may make directly to them or through reports that USO files in the future with the SEC, including annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K.

Introduction

USO, a Delaware limited partnership, is a commodity pool that issues shares that may be purchased and sold on the NYSE Arca. The investment objective of USO is for the daily changes in percentage terms of its shares’ per share NAV to reflect the daily changes in percentage terms of the spot price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the daily changes in the price of the futures contract for light, sweet crude oil traded on the NYMEX that is the near month contract to expire and changes, over a five-day period, into the NYMEX futures contract that is the next month to expire (the “Benchmark Oil Futures Contract”), plus interest earned on USO’s collateral holdings, less USO’s expenses. The change from the near month contract to the next month contract occurs at the beginning of each month and will be approximately proportional, relative to total net assets, over each day of the five-day roll period. “Near month contract” means the next contract traded on the NYMEX due to expire. “Next month contract” means the first contract traded on the NYMEX due to expire after the near month contract. USO seeks to achieve its investment objective by investing so that the average daily percentage change in USO’s NAV for any period of 30 successive valuation days will be within plus/minus ten percent (10%) of the average daily percentage change in the price of the Benchmark Oil Futures Contract over the same period. As a result, investors should be aware that USO would meet its investment objective even if there are significant deviations between changes in its daily NAV and changes in the daily price of the Benchmark Oil Futures Contract provided that the average daily percentage change in USO’s NAV over 30 successive valuation days is within plus/minus ten percent (10%) of the average daily percentage change in the price of the Benchmark Oil Futures Contract over the same period.

USO invests primarily in futures contracts for light, sweet crude oil, other types of crude oil, heating oil, gasoline, natural gas and other petroleum-based fuels that are traded on the NYMEX, ICE Futures or other U.S. and foreign exchanges (collectively, “Oil Futures Contracts”) and to a lesser extent, in order to comply with regulatory requirements, risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants), liquidity requirements, or in view of market conditions, other oil - related investments such as cash-settled options on Oil Futures Contracts, forward contracts for oil, cleared swap contracts and OTC swaps that are based on the price of oil, other petroleum-based fuels, Oil Futures Contracts and indices based on the foregoing (collectively, “Other Oil-Related Investments”). For convenience and unless otherwise specified, Oil Futures Contracts and Other Oil-Related Investments collectively are referred to as “Oil Interests” in this annual report on Form 10-K.

USO’s investment objective is not for its NAV or market price of shares to equal, in dollar terms, the spot price of light, sweet crude oil or any particular futures contract based on light, sweet crude oil, nor is USO’s investment objective for the percentage change in its NAV to reflect the percentage change of the price of any particular futures contract as measured over a time period greater than one day. The general partner of USO, United States Commodity Funds, LLC (“USCF”), believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Oil Futures Contracts and Other Oil-Related Investments.

In addition, USCF believes that market arbitrage opportunities will cause daily changes in USO’s share price on the NYSE Arca on a percentage basis to closely track daily changes in USO’s per share NAV. USCF further believes that the daily changes in the price of the Benchmark Oil Futures Contract have historically closely tracked the daily changes in spot prices of light, sweet crude oil. USCF believes that the net effect of these relationships will be that the daily changes in the price of USO’s shares on the NYSE Arca on a percentage basis will closely track the daily changes in the spot price of a barrel of light, sweet crude oil on a percentage basis, plus interest earned on USO’s collateral holdings, less USO’s expenses.

Table of Contents

The following chart shows, for the period ending December 31, 2025, the rolling 30-day average difference between USO’s NAV and the Benchmark Oil Futures Contract. This is measured by subtracting the return of the Benchmark Oil Futures Contract from the return on USO’s NAV for each of the last thirty business days, and then averaging those thirty differences. The calculation is repeated daily.

Following the significant market volatility that occurred in the Spring of 2020 and the market conditions, regulatory requirements and risk mitigation measures taken by USO and USO’s FCM that impacted USO as a result thereof, USO disclosed its parameters for making decisions regarding the permitted investments USO would hold, including the intended order of priority in selecting investments and the type of investments to be held in its portfolio. Beginning with the monthly roll in September 2023 and ending with the monthly roll in January 2024, USO transitioned its investment portfolio to primarily invest in the Benchmark Oil Futures Contract, consistent with USO’s investment strategy prior to the Spring of 2020. However, USO has had, and will continue to have, the ability to invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract and Other Oil-Related Investments, such as OTC swaps, and USO may make such investments if market conditions (including but not limited to those allowing USO to obtain greater liquidity (i.e., liquidity requirements) or to execute transactions with more favorable pricing), regulatory requirements (including, but not limited to, exchange accountability levels and position limits imposed by NYMEX as well as statutory or regulatory limits), risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants), liquidity requirements, or other factors require USO to do so in order to meet its investment objective. USO may invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract, and/or Other Oil-Related Investments, as a result of, or in response to, any of the foregoing factors. In addition, USO may need to hold significant portions of its portfolio in cash beyond what it has historically held for reasons including (but not limited to) the need to address changes in market conditions, regulatory requirements or risk mitigation measures or the need to satisfy potential margin requirements.

Investments in Oil Futures Contracts beyond the Benchmark Oil Futures Contract and Other Oil-Related Investments could result in wider deviations between the performance of USO’s investments and the Benchmark Oil Futures Contract than if USO’s investments primarily consisted of the Benchmark Oil Futures Contract, and changes in USO’s share price may not be able to track changes in the price of the Benchmark Oil Futures Contract within as narrow a percentage change difference for any period of 30 successive valuation days as it would if USO’s investments primarily consisted of the Benchmark Oil Futures Contract.

Although permitted to do so under its LP Agreement, USO has not leveraged, and does not intend to leverage, its assets through borrowings or otherwise, and USO makes its investments accordingly. Consistent with the foregoing, USO’s investments will take into

Table of Contents

account the need for USO to maintain adequate liquidity to meet its margin and collateral requirements and to avoid, to the extent reasonably possible, USO becoming leveraged. If market conditions require it, these risk reduction procedures, including changes to USO’s investments, may occur on short notice.

Regulatory Disclosure

The regulation of commodity interest trading in the United States and other countries is an evolving area of the law. Below are certain key regulatory requirements that are, or may be, relevant to USO. The various statements made in this summary are subject to modification by legislative action and changes in the rules and regulations of the SEC, Financial Industry Regulatory Authority (“FINRA”), CFTC, NFA, the futures exchanges, clearing organizations and other regulatory bodies. Pending final resolution of all applicable regulatory requirements, some examples of how new rules and regulations could impact USO are discussed in “Item 1. Business” in this annual report on Form 10-K.

Exchange Accountability Levels, Position Limits and Price Fluctuation Limits . Designated contract markets (“DCMs”), such as the NYMEX and ICE Futures, have established accountability levels and position limits on the maximum net long or net short futures contracts in commodity interests that any person or group of persons under common trading control (other than as a hedge, which an investment by USO is not) may hold, own or control. These levels and position limits apply to the futures contracts that USO invests in to meet its investment objective. In addition to accountability levels and position limits, the NYMEX and ICE Futures also set daily price fluctuation limits on futures contracts. The daily price fluctuation limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price. Once the daily price fluctuation limit has been reached in a particular futures contract, no trades may be made at a price beyond that limit.

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 December 31, 2025, USO held 13,180 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 year ended December 31, 2025, including when it held a maximum of 16,767 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.

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 year ended December 31, 2025, 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.

Federal Position Limits

Part 150 of the CFTC’s regulations (the “Position Limits Rule”) establishes federal position limits for 25 core referenced futures contracts (comprised of agricultural, energy and metals futures contracts), futures and options linked to the core referenced futures contracts, and swaps that are economically equivalent to the core referenced futures contracts that all market participants must comply with, with certain exemptions. The Benchmark Oil Futures Contract is subject to position limits under the Position Limits Rule, and

Table of Contents

USO’s trading does not qualify for an exemption therefrom. Accordingly, the Position Limits Rule could inhibit USO’s ability to invest in the Benchmark Oil Futures Contract and thereby could negatively impact the ability of USO to meet its investment objective.

Position limits may potentially cause a tracking error between the price of USO’s shares and the price of the Benchmark Oil Futures Contract. This may in turn prevent investors from being able to effectively use USO as a way to hedge against crude oil related losses or as a way to indirectly invest in crude oil.

USO has not limited the size of its offering and intends to utilize substantially all of its proceeds to purchase Oil Futures Contracts and Other Oil-Related Investments to the extent possible. If USO encounters accountability levels, position limits (including those set by the Position Limits Rule), or price fluctuation limits for Oil Futures Contracts on the NYMEX or ICE Futures, it may then, if permitted under applicable regulatory requirements, purchase Oil Futures Contracts on other exchanges that trade listed crude oil futures or enter into swaps or other permitted investments to meet its investment objective. In addition, if USO exceeds accountability levels on either the NYMEX or ICE Futures and is required by such exchanges to reduce its holdings, such reduction could potentially cause a tracking error between the price of USO’s shares and the price of the Benchmark Oil Futures Contract.

Margin for OTC Swaps

Rules put in place by U.S. federal banking regulators, the CFTC and the SEC require the daily exchange of variation margin and initial margin for swaps between swap dealers, major swap participants, security-based swap dealers, and major security-based swap participants (“Swap Entities”) and swaps between Swap Entities and their counterparties that are “financial end-users” (such rules, the “Margin Rules”). The Margin Rules require Swap Entities to exchange variation margin with all of their counterparties who are financial end-users. The minimum variation margin amount is the daily mark-to-market change in the value of the swap, taking into account the amount of variation margin previously posted or collected. Swap Entities are required to exchange initial margin with their financial end-users who have “material swaps exposure” (i.e., an average daily aggregate notional of $8 billion or more in non-cleared swaps calculated in accordance with the Margin Rules). The Margin Rules specify the types of collateral that may be posted or collected as initial margin or variation margin (generally cash, certain government, government-sponsored enterprise securities, certain liquid debt, certain equity securities, certain eligible publicly traded debt, and gold) and sets forth haircuts for certain collateral asset classes.

USO is not a Swap Entity under the Margin Rules, but it is a financial end-user. Accordingly, USO will be subject to the variation margin requirements of the Margin Rules for any swaps that it enters into. However, USO does not have material swaps exposure under the Margin Rules and, accordingly, USO will not be subject to the initial margin requirements of the Margin Rules.

Mandatory Trading and Clearing of Swaps

CFTC regulations require that certain swap transactions be executed on organized exchanges or “swap execution facilities” and cleared through regulated clearing organizations (“derivative clearing organizations” (“DCOs”)), if the CFTC mandates the central clearing of a particular class of swap and such swap is “made available to trade” on a swap execution facility. Currently, swap dealers, major swap participants, commodity pools, certain private funds and entities predominantly engaged in activities that are financial in nature are required to execute on a swap execution facility, and clear, certain interest rate swaps and index-based credit default swaps. As a result, if USO enters into an interest rate or index-based credit default swap that is subject to these requirements, such swap will be required to be executed on a swap execution facility and centrally cleared. Mandatory clearing and “made available to trade” determinations with respect to additional types of swaps may be issued in the future, and, when finalized, could require USO to electronically execute and centrally clear certain OTC instruments presently entered into and settled on a bi-lateral basis. If a swap is required to be cleared, initial and variation margin requirements are set by the relevant clearing organization, subject to certain regulatory requirements and guidelines. Additional margin may be required and held by USO’s FCMs.

Other Requirements for Swaps

In addition to the margin requirements described above, swaps that are not required to be cleared and executed on a SEF but that are executed bilaterally are also subject to various requirements pursuant to CFTC regulations, including, among other things, reporting and recordkeeping requirements and, depending on the status of the counterparties, trading documentation requirements and dispute resolution requirements.

Derivatives Regulations in Non-U.S. Jurisdictions

In addition to U.S. laws and regulations, USO may be subject to non-U.S. derivatives laws and regulations if it engages in futures and/or swap transactions with non-U.S. persons. For example, USO may be impacted by European laws and regulations to the extent that it

Table of Contents

engages in futures transactions on European exchanges or derivatives transactions with European entities. Other jurisdictions impose requirements applicable to futures and derivatives that are similar to those imposed by the U.S., including position limits, margin, clearing and trade execution requirements.

The CFTC is generally prohibited by statute from regulating trading on non-U.S. futures exchanges and markets. The CFTC, however, has adopted regulations relating to the marketing of non-U.S. futures contracts in the United States. These regulations permit certain contracts on non-U.S. exchanges to be offered and sold in the United States.

Natural disasters, public health disruptions (such as the COVID-19 pandemic), and international armed conflicts could impact the price of commodities and/or the value, pricing and liquidity of USO’s investments or assets which, in turn, could cause the loss of your investment in USO.

Natural or environmental disasters, such as earthquakes, fires, floods, hurricanes, tsunamis and other severe weather-related phenomena generally, and widespread disease, including public health disruptions, pandemics and epidemics (for example, the COVID-19 pandemic), can be highly disruptive to economies and markets. Such events can, directly or indirectly, negatively impact, and/or cause volatility in, the price of commodities such as crude oil and the value, pricing, and liquidity of the investments or other assets held by USO.

Geopolitical conflict, including war and armed conflicts (such as the Russia-Ukraine war, conflicts in the Middle East, and the expansion of such conflicts in surrounding areas), sanctions, the introduction of or changes in tariffs or trade barriers, global or local recessions, and acts of terrorism, can also, directly or indirectly, negatively impact, and/or cause volatility in, the price of commodities such as crude oil and the value, pricing, and liquidity of the investments or other assets held by USO. A negative impact on, or volatility in, the price of crude oil or the value, pricing and liquidity of USO’s investments or other assets resulting from the occurrence of any of the aforementioned events, or similar events, could cause you to lose all, or substantially all, of your investment in USO.

USO may be subject to interest rate risk, which may prevent USO from investing fully at prevailing rates until any current investments in Treasuries mature in order to avoid selling those investments at a loss.

Interest rate risk is the risk that fixed income securities and other investments in USO’s portfolio will fluctuate in value because of a change in interest rates. Interest rate changes can be sudden and unpredictable, and USO may lose money because of movements in interest rates. When interest rates rise, the value of fixed income securities typically falls. In a rising interest rate environment, USO may not be able to fully invest at prevailing rates until any current investments in Treasuries mature in order to avoid selling those investments at a loss. Interest rate risk is generally lower for shorter term investments and higher for longer term investments. In addition, in rising interest rate environments, it is possible that the Treasuries held by USO will decline in value. When interest rates fall, USO may be required to reinvest the proceeds from the sale, redemption or early prepayment of a Treasury Bill or money market security at a lower interest rate.

As inflation increases, the present value of USO’s assets may decline.

Inflation is a general increase in the overall price level of goods and services in the economy. The United States Federal Reserve has a stated goal of maintaining a two percent increase in inflation over the long run, as measured by the annual change in the price index for personal consumption expenditures. Following the COVID-19 pandemic, the United States experienced inflation above the Federal Reserve’s stated two percent goal. Other world economies similarly experienced elevated inflation rates. The Federal Reserve increased interest rates and successfully reduced inflation so that it is close to the stated two percent goal. As a result, in 2024, the Federal Reserve began reducing interest rates. However, the rate of inflation in the United States is still above the stated two percent goal. Inflation has the effect of eroding the value of cash or bonds. In a high inflation environment, the value of USO’s cash and Treasury investments may decline.

USO may potentially lose money by investing in government money market funds.

USO invests in government money market funds. Although such government money market funds seek to preserve the value of an investment at $1.00 per share, there is no guarantee that they will be able to do so and USO may lose money by investing in a government money market fund. An investment in a government money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation (the “FDIC”) or any other government agency. The share price of a government money market fund can fall below the $1.00 share price. USO cannot rely on or expect a government money market fund’s adviser or its affiliates to enter into support agreements or take other actions to maintain the government money market fund’s $1.00 share price. The credit quality of a government money market fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact

Table of Contents

on the government money market fund’s share price. Due to fluctuations in interest rates, the market value of securities held by a government money market fund may vary. A government money market fund’s share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets.

Price Movements

Crude oil futures prices were volatile during the year ended December 31, 2025. The price of the Benchmark Oil Futures Contract started the year at $71.72 per barrel. The high of the year was on January 15, 2025 when the price reached $78.84 per barrel. The low for the year was on December 16, 2025, which was $55.13 per barrel. The year ended with the Benchmark Oil Futures Contract at $57.42 per barrel, a decrease of approximately (19.94)% over the year. USO’s per share NAV began the year at $75.45 and ended the year at $69.10 on December 31, 2025, a decrease of approximately (8.42)% over the year. The Benchmark Oil Futures Contract prices listed above began with the February 2025 contracts and ended with the February 2026 contracts. The decrease of approximately (19.94)% 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.”

During the year ended December 31, 2025, the crude oil futures market experienced states of mild contango. On days when the market was in contango the price of the near month crude Oil Futures Contract was lower than the price of the next month crude Oil Futures Contract, or contracts further away from expiration. On days when the market was in backwardation, the price of the near month crude Oil Futures Contract was higher than the price of the next month crude Oil Futures Contract or contracts further away from expiration. For a discussion of the impact of backwardation and contango on total returns, see “Term Structure of Crude Oil Prices and the Impact on Total Returns” below.

Valuation of Oil Futures Contracts and the Computation of the Per Share NAV

The per share NAV of USO’s shares is calculated once each NYSE Arca trading day. The per share NAV for a particular trading day is released after 4:00 p.m. New York time. Trading during the core trading session on the NYSE Arca typically closes at 4:00 p.m. New York time. USO’s Administrator uses the settlement price determined by NYMEX at 2:30 p.m. Eastern time for the Oil Futures Contracts held on the NYMEX and the settlement price determined by ICE Futures at 2:30 p.m. Eastern time for the Oil Futures Contracts held on ICE Futures, but calculates or determines the value of all other USO investments, other futures contracts, as of the earlier of the close of the NYSE Arca or 4:00 p.m. New York time.

Results of Operations and the Crude Oil Market

Results of Operations.

As of December 31, 2025, USO had 12,823,603 shares outstanding. On August 29, 2023, the SEC declared effective a registration statement filed by USO that registered an unlimited number of shares. As a result, USO has an unlimited number of shares that can be issued in the form of Creation Baskets. More shares may have been issued by USO than are outstanding due to the redemption of shares.

On April 28, 2020, after the close of trading on the NYSE Arca, USO effected a 1-for-8 reverse share split and post-split shares of USO began trading on April 29, 2020. As a result of the reverse share split, every eight pre-split shares of USO were automatically exchanged for one post-split share. Immediately prior to the reverse split, there were 1,482,900,000 shares of USO issued and outstanding, representing a per share NAV of $2.04. Immediately after the effect of the reverse share split, the number of issued and outstanding shares of USO decreased to 185,362,500, not accounting for fractional shares, and the per share NAV increased to $16.35.

Portfolio Expenses. USO’s expenses consist of investment management fees, brokerage fees and commissions, certain offering costs, licensing fees, registration fees, the fees and expenses of the independent directors of USCF and expenses relating to tax accounting and reporting requirements. The management fee that USO pays to USCF is calculated as a percentage of the total net assets of USO. The fee is accrued daily and paid monthly.

The decrease in the per share NAV for the year ended December 31, 2025, compared to the year ended December 31, 2024, was due primarily to lower prices for WTI crude oil and the related decrease in the value of the Oil Futures Contracts in which USO held and traded.

Average interest rates earned on short-term investments held by USO, including cash, cash equivalents and Treasuries, were lower during the year ended December 31, 2025, compared to the year ended December 31, 2024. As a result, the amount of income earned by USO as a percentage of average daily total net assets was lower during the year ended December 31, 2025, compared to the year ended December 31, 2024. To the degree that the aggregate yield is lower, the net expense ratio, inclusive of income, will be higher.

The decrease in total fees and other expenses excluding management fees for the year ended December 31, 2025, compared to the year ended December 31, 2024 was due primarily to a decrease in tax reporting and professional fees.

The decrease in total commissions accrued to brokers for the year ended December 31, 2025, compared to the year ended December 31, 2024, was due primarily to the number of Oil Futures Contracts being held and traded.

Tracking USO’s Benchmark

USCF seeks to manage USO’s portfolio such that changes in its average daily per share NAV, on a percentage basis, closely track the daily changes in the average price of the Benchmark Oil Futures Contract, also on a percentage basis. Specifically, USCF seeks to manage the portfolio such that over any rolling period of 30-valuation days, the average daily change in USO’s per share NAV is within a range of 90% to 110% (0.9 to 1.1) of the average daily change in the price of the Benchmark Oil Futures Contract. As an example, if the average daily movement of the price of the Benchmark Oil Futures Contract for a particular 30-valuation day time period was 0.50% per day, USCF would attempt to manage the portfolio such that the average daily movement of the per share NAV during that same time period fell between 0.45% and 0.55% (i.e., between 0.9 and 1.1 of the benchmark’s results). USO’s portfolio management goals do not include trying to make the nominal price of USO’s per share NAV equal to the nominal price of the current Benchmark Oil Futures Contract or the spot price for light, sweet crude oil. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Oil Futures Contracts and Other Oil-Related Investments.

For the 30-valuation days ended December 31, 2025, the average daily change in the Benchmark Oil Futures Contract was 0.115%, while the average daily change in the per share NAV of USO over the same time period was (0.104)%. 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 December 31, 2025, the average daily change in the Benchmark Oil Futures Contract was 0.001%, while the average daily change in the per share NAV of USO over the same time period was (0.010)%. 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.

The following two charts demonstrate the correlation between the changes in USO’s NAV and the changes in the Benchmark Oil Futures Contract. The first chart below shows the daily movement of USO’s per share NAV versus the daily movement of the Benchmark Oil Futures Contract for the 30 valuation day period ended December 31, 2025. The second chart below shows the monthly total returns of USO as compared to the monthly value of the Benchmark Oil Futures Contract for the five years ended December 31, 2025.

An alternative tracking measurement of the return performance of USO versus the return of its Benchmark Oil Futures Contract can be calculated by comparing the actual return of USO, measured by changes in its per share NAV, versus the expected changes in its per

Table of Contents

share NAV under the assumption that USO’s returns had been exactly the same as the daily changes in its Benchmark Oil Futures Contract.

For the year ended December 31, 2025, the actual total return of USO as measured by changes in its per share NAV was (8.42)%. 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 December 31, 2025 of $69.10. 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 $67.49 as of December 31, 2025, for a total return over the relevant time period of (10.55)% The difference between the actual per share NAV total return of USO of (8.42)% and the expected total return based on the Benchmark Oil Futures Contract of (10.55)% was a difference over the time period of 2.13%, 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 lower than daily changes in the price of the Benchmark Oil Futures Contract.

By comparison, for the year ended December 31, 2024, the actual total return of USO as measured by changes in its per share NAV was 12.76%. This is based on an initial per share NAV of $66.91 as of December 31, 2023 and an ending per share NAV as of December 31, 2024 of $75.45. 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 $71.25 as of December 31, 2024, for a total return over the relevant time period of 6.47%. The difference between the actual per share NAV total return of USO of 12.76% and the expected total return based on the Benchmark Oil Futures Contract of 6.47% was a difference over the time period of 6.29%, 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 Futures contract tended 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.

As a result of market conditions and the regulatory response that occurred in March 2020 and thereafter, large numbers of USO shares that were purchased during a short period of time, and regulatory accountability levels and position limits on oil futures contracts that were imposed on USO, and risk mitigation measures imposed by its FCMs, USO invested in Oil Futures Contracts in months other than the Benchmark Oil Futures Contract.

Beginning with the monthly roll in September 2023 and ending with the monthly roll in January 2024, USO transitioned its investment portfolio to primarily invest in the Benchmark Oil Futures Contract, consistent with USO’s investment strategy prior to the Spring of 2020. However, USO has had, and will continue to have, the ability to invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract and Other Oil-Related Investments, such as OTC swaps, and USO may make such investments if market conditions (including but not limited to those allowing USO to obtain greater liquidity (i.e., liquidity requirements) or to execute transactions with more favorable pricing), regulatory requirements (including, but not limited to, exchange accountability levels and position limits imposed by NYMEX as well as statutory or regulatory limits), risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants), liquidity requirements, or other factors require USO to do so in order to meet its investment objective. USO may invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract, and/or Other Oil-Related Investments, as a result of, or in response to, any of the foregoing factors. In addition, USO may need to hold significant portions of its portfolio in cash beyond what it has historically held for reasons including (but not limited to) the need to address the changes in market conditions, regulatory requirements or risk mitigation measures or the need to satisfy potential margin requirements.

During the fourth quarter of 2025 the rolling 30 day average daily difference between the return of USO’s NAV and the Benchmark Oil Futures Contract was (0.01)% or (1.0) basis points).

There are three factors that typically have impacted or are most likely to impact USO’s ability to accurately track Benchmark Oil Futures Contract in addition to the foregoing.

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

Table of Contents

higher or lower relative to the daily changes in the Benchmark Oil Futures Contract. During the year ended December 31, 2025, 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 year ended December 31, 2025. 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 year ended December 31, 2025, 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.

Term Structure of Crude Oil Futures Prices and the Impact on Total Returns. Several factors determine the total return from investing in futures contracts. One factor arises from “rolling” futures contracts that will expire at the end of the current month (the “near” or “front” month contract) forward each month prior to expiration. For a strategy that entails holding the near month contract, the price relationship between that futures contract and the next month futures contract will impact returns. For example, if the price of the near month futures contract is higher than the next futures month contract (a situation referred to as “backwardation”), then absent any other change, the price of a next month futures contract tends to rise in value as it becomes the near month futures contract and approaches expiration. Conversely, if the price of a near month futures contract is lower than the next month futures contract (a situation referred to as “contango”), then absent any other change, the price of a next month futures contract tends to decline in value as it becomes the near month futures contract and approaches expiration.

As an example, assume that the price of crude oil for immediate delivery, is $50 per barrel, and the value of a position in the near month futures contract is also $50. Over time, the price of crude oil will fluctuate based on a number of market factors, including demand for oil relative to supply. The value of the near month futures contract will likewise fluctuate in reaction to a number of market factors. If an investor seeks to maintain a position in a near month futures contract and not take delivery of physical barrels of crude oil, the investor must sell the current near month futures contract as it approaches expiration and invest in the next month futures contract. In order to continue holding a position in the current near month futures contract, this “roll” forward of the futures contract must be executed every month.

Contango and backwardation are natural market forces that have impacted the total return on an investment in USO’s shares during the past year relative to a hypothetical direct investment in crude oil. In the future, it is likely that the relationship between the market price of USO’s shares and changes in the spot prices of light, sweet crude oil will continue to be impacted by contango and backwardation. It is important to note that this comparison ignores the potential costs associated with physically owning and storing crude oil, which could be substantial.

Table of Contents

If the futures market is in backwardation, e.g., when the price of the near month futures contract is higher than the price of the next month futures contract, the investor would buy a next month futures contract for a lower price than the current near month futures contract. Assuming the price of the next month futures contract was $49 per barrel, or 2% cheaper than the $50 near month futures contract, then, hypothetically, and assuming no other changes (e.g., to either prevailing crude oil prices or the price relationship between the spot price, the near month contract and the next month contract, and, ignoring the impact of commission costs and the income earned on cash and/or cash equivalents), the value of the $49 next month futures contract would rise to $50 as it approaches expiration. In this example, the value of an investment in the next month futures contract would tend to outperform the spot price of crude oil. As a result, it would be possible for the new near month futures contract to rise 12% while the spot price of crude oil may have risen a lower amount, e.g., only 10%. Similarly, the spot price of crude oil could have fallen 10% while the value of an investment in the futures contract might have fallen another amount, e.g., only 8%. Over time, if backwardation remained constant, this difference between the spot price and the futures contract price would continue to increase.

If the futures market is in contango, an investor would be buying a next month futures contract for a higher price than the current near month futures contract. Again, assuming the near month futures contract is $50 per barrel, the price of the next month futures contract might be $51 per barrel, or 2% more expensive than the front month futures contract. Hypothetically, and assuming no other changes, the value of the $51 next month futures contract would fall to $50 as it approaches expiration. In this example, the value of an investment in the second month would tend to underperform the spot price of crude oil. As a result, it would be possible for the new near month futures contract to rise only 10% while the spot price of crude oil may have risen a higher amount, e.g., 12%. Similarly, the spot price of crude oil could have fallen 10% while the value of an investment in the second month futures contract might have fallen another amount, e.g., 12%. Over time, if contango remained constant, this difference between the spot price and the futures contract price would continue to increase.

The chart below compares the daily price of the near month crude oil futures contract to the price of the 13 th month crude oil futures contract (i.e., a contract one year forward) over the last 10 years. When the price of the near month futures contract is higher than the price of the 13 th month futures contract, the market would be described as being in backwardation. When the price of the near month futures contract is lower than the 13 th month futures contract, the market would be described as being in contango. Although the price of the near month futures contract and the price of the 13 th month futures contract tend to move together, it can be seen that at times the near month futures contract prices are higher than the 13 th month futures contract prices (backwardation) and, at other times, the near month futures contract prices are lower than the 13 th month futures contract prices (contango).

An alternative way to view the same data is to subtract the dollar price of the 13 th  month crude oil futures contract from the dollar price of the near month crude oil futures contract, as shown in the chart below. When the difference is positive, the market is in backwardation. When the difference is negative, the market is in contango. The crude oil market spent time in both backwardation and contango during the last ten years.

*PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

An investment in a portfolio that owned only the near month crude oil futures contract would likely produce a different result than an investment in a portfolio that owned an equal number of each of the near 12 months of crude oil futures contracts. Generally speaking, when the crude oil futures market is in backwardation, a portfolio of only the near month crude oil futures contract may tend to have a higher total return than a portfolio of 12 months of the crude oil futures contract. Conversely, if the crude oil futures market was in contango, the portfolio containing only 12 months of crude oil futures contracts may tend to outperform the portfolio holding only the near month crude oil futures contract.

Historically, the crude oil futures markets have experienced periods of contango and backwardation, with backwardation being in place somewhat less often than contango since oil futures trading started in 1983. Following the global financial crisis in the fourth quarter of 2008, the crude oil market moved into contango and remained primarily in contango until 2013. In 2014, global crude oil inventories grew rapidly after the Organization of the Petroleum Exporting Countries (“OPEC”) voted to defend its market share against U.S. shale-oil producers, resulting in another period during which the crude oil market remained primarily in contango. This period of contango continued through December 31, 2017. Declining global crude oil inventories caused the market to flip into backwardation at the beginning of 2018 through late October 2018, at which point ongoing supply growth in the U.S., combined with increased OPEC

production, once again led market participants to fear another global glut of crude oil. The crude oil market was primarily in contango the first half of 2019 and in backwardation during the second half of 2019. Crude oil flipped back into contango in January 2020 and remained predominantly in contango throughout 2020.

In March 2020, contango dramatically increased and reached historic levels during the economic crisis arising from the COVID-19 pandemic, related supply chain disruptions and ongoing disputes among oil producing countries. This level of contango was due to significant market volatility that occurred in crude oil markets as well as oil futures markets. Crude oil prices collapsed in the wake of the COVID-19 demand shock, which reduced global petroleum consumption, and the price war launched by Saudi Arabia at the beginning of March 2020 in response to Russia’s unwillingness to participate in extending previously agreed upon supply cuts. An estimated twenty million barrels a day of crude demand evaporated as a result of quarantines and massive drops in industrial and manufacturing activity. Eventually, the United States, OPEC, Russia, and other oil producers around the world agreed to a historic 9.7 million barrel per day cut to crude supply. The supply cut along with the partial reopening of economies during the third quarter of 2020 reduced some of the unprecedented volatility that oil markets experienced in the Spring of 2020.

During the twelve months ended December 31, 2020, the crude oil futures market spent time in both a state of contango and backwardation as measured by the difference between the front month and the second month contract, whereas the crude oil futures market has primarily been in a state of backwardation since 2021 as measured by the difference between the front month and the second month contract.

As a result of market and regulatory conditions, including significant market volatility, large numbers of USO shares purchased during a short period of time, applicable regulatory accountability levels and position limits on oil futures contracts and risk mitigation measures that were taken by USO and USO’s FCM in 2020, USO invested in Oil Futures Contracts with expiration dates for months later than that of the Benchmark Oil Futures Contract. Holdings in later month contracts will typically cause USO to experience lesser effects from contango and backwardation than would be the case if USO’s holdings were primarily in oil futures contracts in the first month or second month. Beginning with the monthly roll in September 2023 and ending with the monthly roll in January 2024, USO transitioned its investment portfolio to primarily invest in the Benchmark Oil Futures Contract, consistent with USO’s investment strategy prior to the Spring of 2020. However, USO has had, and will continue to have, the ability to invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract and Other Oil-Related Investments, such as OTC swaps, and USO may make such investments if market conditions (including but not limited to those allowing USO to obtain greater liquidity (i.e., liquidity requirements) or to execute transactions with more favorable pricing), regulatory requirements (including, but not limited to, exchange accountability levels and position limits imposed by NYMEX as well as statutory or regulatory limits), risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants), liquidity requirements, or other factors require USO to do so in order to meet its investment objective. USO may invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract, and/or Other Oil-Related Investments, as a result of, or in response to, any of the foregoing factors. In addition, USO may need to hold significant portions of its portfolio in cash beyond what it has historically held for reasons including (but not limited to) the need to address the changes in market conditions, regulatory requirements or risk mitigation measures or the need to satisfy potential margin requirements.

Crude Oil Market . During the year ended December 31, 2025, the price of the front month WTI crude oil futures contract traded in a range between $55.27 to $80.04. Prices decreased (19.94)% from December 31, 2024 through December 31, 2025, finishing the year at $57.42.

In 2025, growing supplies weighed on crude oil prices. Supply exceeded demand throughout the year and the gap between output and consumption widened significantly from 0.6 mbd excess supply at the end of 2024 to 2.8 mbd by the end of 2025. U.S. crude oil production averaged 13.5 mbd. U.S. production rose significantly over the last five years. OPEC crude production declined from late 2022 through the third quarter of 2024 as the cartel supported prices with overall quotas and voluntary output cuts by certain countries, particularly Saudi Arabia. OPEC output rose from approximately 27.5 mbd to 29.0 mbd during 2025, but remained below pre- and post-pandemic highs. The cartel announced plans to begin unwinding voluntary cuts and increasing quotas in 2024 and began to do so after delaying and adjusting these plans several times. While OPEC steadily increased output several times in 2025, it has also reaffirmed its commitment to maintaining oil market stability and retains the flexibility to change plans as market conditions warrant. Nevertheless, the long-expected and repeatedly delayed reduction of quotas and voluntary cuts is finally underway. While not a complete policy reversal, the “OPEC put” which kept a floor on prices over the last several years has likely moved lower. 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, and production may not rise as much in the future as it has in the recent past. Technology, geology, and economics tend to be

Table of Contents

larger determinants of U.S. production levels than political policy. 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 would reduce demand for crude oil.

Geopolitics continue to add complexity to the supply-demand equation. Tensions and flare ups supported prices and contributed to price volatility through 2025. As an example, in June of 2025, Israel and the United States attacked Iran’s nuclear facilities, raising speculation that Iran might attempt to close the Strait of Hormuz. As approximately 20% of global petroleum consumption transits the Strait daily, this could have had a significant effect on prices. As it stands, Iran did not close the Strait, and prices fell back to the mid-$65 range after briefly topping $75. Starting off 2026, the U.S.’s latest posturing against Iran and its actions in Venezuela, as well as ongoing conflicts in Ukraine and the Middle East continue to raise uncertainty about future supply. Ongoing global tensions, with existing and potential conflicts in various regions, remain a flash point for risk to crude oil supply, which could raise prices. Conversely, any resolution of geopolitical conflicts could ease supply disruptions, sanctions, and price volatility, which could lower prices.

Crude Oil Price Movements in Comparison to Other Energy Commodities and Investment Categories. USCF believes that investors frequently measure the degree to which prices or total returns of one investment or asset class move up or down in value in concert with another investment or asset class. Statistically, such a measure is usually done by measuring the correlation of the price movements of the two different investments or asset classes over some period of time. The correlation is scaled between 1 and -1, where 1 indicates that the two investment options move up or down in price or value together, known as “positive correlation,” and -1 indicates that they move in completely opposite directions, known as “negative correlation.” A correlation of 0 would mean that the movements of the two are neither positively nor negatively correlated, known as “non-correlation.” That is, the investment options sometimes move up and down together and other times move in opposite directions.

For the ten-year time period between December 31, 2015 and December 31, 2025, the table below compares the monthly movements of crude oil prices versus the monthly movements of the prices of several other energy commodities, such as natural gas, diesel-heating oil, and unleaded gasoline, as well as several major non-commodity investment asset classes, such as large cap U.S. equities, U.S. government bonds and global equities.

Investors are cautioned that the historical price relationships between crude oil and various other energy commodities, as well as other investment asset classes, as measured by correlation may not be reliable predictors of future price movements and correlation results. The results pictured above would have been different if a different range of dates had been selected. USCF believes that crude oil has historically not demonstrated a strong correlation with equities or bonds over long periods of time. However, USCF also believes that in the future it is possible that crude oil could have long term correlation results that indicate prices of crude oil more closely track the movements of equities or bonds. In addition, USCF believes that, when measured over time periods shorter than ten years, there will always be some periods where the correlation of crude oil to equities and bonds will be either more strongly positively correlated or more strongly negatively correlated than the long term historical results suggest.

The correlations between crude oil, natural gas, diesel-heating oil and gasoline are relevant because USCF endeavors to invest USO’s assets in Oil Futures Contracts and Other Oil-Related Investments so that daily changes in percentage terms in USO’s per share NAV correlate as closely as possible with daily changes in percentage terms in the price of the Benchmark Oil Futures Contract. If certain other fuel-based commodity futures contracts do not closely correlate with the crude-oil futures contract, then their use could lead to greater tracking error. As noted above, USCF also believes that the changes in percentage terms in the price of the Benchmark Oil Futures Contract will closely correlate with changes in percentage terms in the spot price of light, sweet crude oil.

Preparation of the financial statements and related disclosures in compliance with accounting principles generally accepted in the United States of America requires the application of appropriate accounting rules and guidance, as well as the use of estimates. USO’s application of these policies involves judgments and actual results may differ from the estimates used.

USCF has evaluated the nature and types of estimates that it makes in preparing USO’s financial statements and related disclosures and has determined that the valuation of its investments, which are not traded on a United States or internationally recognized futures exchange (such as forward contracts and OTC swaps) involves a critical accounting policy. The values which are used by USO for its Oil Futures Contracts are provided by its commodity broker who uses market prices when available, while OTC swaps are valued based on the present value of estimated future cash flows that would be received from or paid to a third party in settlement of these derivative contracts prior to their delivery date and valued on a daily basis. In addition, USO estimates interest and dividend income on a daily basis using prevailing rates earned on its cash and cash equivalents. These estimates are adjusted to the actual amount received on a monthly basis and the difference, if any, is not considered material.

Liquidity and Capital Resources

USO has not made, and does not anticipate making, use of borrowings or other lines of credit to meet its obligations. USO has met, and it is anticipated that USO will continue to meet, its liquidity needs in the normal course of business from the proceeds of the sale of its

investments, or from the Treasuries, cash and/or cash equivalents that it intends to hold at all times. USO’s liquidity needs include: redeeming shares, providing margin deposits for its existing Oil Futures Contracts or the purchase of additional Oil Futures Contracts and posting collateral for its OTC swaps, if applicable, and payment of its expenses, summarized below under “Contractual Obligations.”

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 year ended December 31, 2025, 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 year ended December 31, 2025, USO did not use other assets to pay expenses. To the extent income exceed expenses, USO’s NAV will be positively impacted.

Although permitted to do so under its LP Agreement, USO has not leveraged, and does not intend to leverage, its assets through borrowings or otherwise, and USO makes its investments accordingly. Consistent with the foregoing, USO’s investments will take into account the need for USO to maintain adequate liquidity to meet its margin and collateral requirements and to avoid, to the extent reasonably possible, USO becoming leveraged. If market conditions require it, these risk reduction procedures, including changes to USO’s investments, may occur on short notice.

USO does not and will not borrow money or use debt to satisfy its margin or collateral obligations in respect of its investments, but it could become leveraged if USO were to hold insufficient assets that would allow it to meet not only the current, but also future, margin or collateral obligations required for such investments. Such a circumstance could occur if USO were to hold assets that have a value of less than zero.

USCF endeavors to have the value of USO’s Treasuries, cash and cash equivalents, whether held by USO or posted as margin or other collateral, at all times approximate the aggregate market value of its obligations under its Oil Futures Contracts and Other Oil-Related Investments.

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 year ended December 31, 2025, 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.

Since the March 23, 2007, USO has been responsible for expenses relating to: (i) management fees, (ii) brokerage fees and commissions, (iii) licensing fees for the use of intellectual property, (iv) ongoing registration expenses in connection with offers and sales of its shares subsequent to the initial offering, (v) other expenses, including tax reporting costs, (vi) fees and expenses of the independent directors of USCF and (vii) other extraordinary expenses not in the ordinary course of business.

USO may terminate at any time, regardless of whether USO has incurred losses, subject to the terms of the LP Agreement. In particular, unforeseen circumstances, including, but not limited to, (i) market conditions, regulatory requirements, risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants) that would lead USO to determine that it could no longer foreseeably meet its investment objective or that USO’s aggregate net assets in relation to its operating expenses or its margin or collateral requirements make the continued operation of USO unreasonable or imprudent, or (ii) adjudication of incompetence, bankruptcy, dissolution, withdrawal, or removal of USCF as the general partner of USO could cause USO, to terminate unless a majority interest of the limited partners within 90 days of the event elects to continue the partnership and appoints a successor general partner, or the affirmative vote of a majority in interest of the limited partners subject to certain conditions. However, no level of losses will require USCF to terminate USO. USO’s termination would cause the liquidation and potential loss of an investor’s investment. Termination could also negatively affect the overall maturity and timing of an investor’s investment portfolio.

Market Risk

Trading in Oil Futures Contracts and Other Oil-Related Investments, such as forwards, involves USO entering into contractual commitments to purchase or sell oil at a specified date in the future. The aggregate market value of the contracts will significantly exceed USO’s future cash requirements since USO intends to close out its open positions prior to settlement. As a result, USO is generally only subject to the risk of loss arising from the change in value of the contracts. USO considers the “fair value” of its derivative instruments to be the unrealized gain or loss on the contracts. The market risk associated with USO’s commitments to purchase oil is limited to the aggregate market value of the contracts held. However, should USO enter into a contractual commitment to sell oil, it would be required to make delivery of the oil at the contract price, repurchase the contract at prevailing prices or settle in cash. Since there are no limits on the future price of oil, the market risk to USO could be unlimited.

USO’s exposure to market risk depends on a number of factors, including the markets for oil, the volatility of interest rates and foreign exchange rates, the liquidity of the Oil Futures Contracts and Other Oil-Related Investments markets and the relationships among the contracts held by USO. Drastic market occurrences could ultimately lead to the loss of all or substantially all of an investor’s capital.

Credit Risk

When USO enters into Oil Futures Contracts and Other Oil-Related Investments, it is exposed to the credit risk that the counterparty will not be able to meet its obligations. The counterparty for the Oil Futures Contracts traded on the NYMEX and on most other futures exchanges is the clearinghouse associated with the particular exchange. In general, in addition to margin required to be posted by the clearinghouse in connection with cleared trades, clearinghouses are backed by their members who may be required to share in the financial burden resulting from the nonperformance of one of their members and, therefore, this additional member support should significantly reduce credit risk. USO is not currently a member of any clearinghouse. Some foreign exchanges are not backed by their clearinghouse members but may be backed by a consortium of banks or other financial institutions. There can be no assurance that any counterparty, clearinghouse, or their members or their financial backers will satisfy their obligations to USO in such circumstances.

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.

USO may purchase OTC swaps in the future periods, see “Item 3 Quantitative and Qualitative Disclosures About Market Risk” in this annual report on Form 10-K for a discussion of OTC swaps.

As of December 31, 2025, USO held cash deposits and short - term investments in the amount of $892,556,521 with the custodian and FCMs. Some or all of these amounts held by a custodian or an FCM, as applicable, may be subject to loss should USO’s custodian or FCMs, as applicable, cease operations.

Off Balance Sheet Financing

As of December 31, 2025, USO had no loan guarantee, credit support or other off-balance sheet arrangements of any kind other than agreements entered into in the normal course of business, which may include indemnification provisions relating to certain risks that service providers undertake in performing services which are in the best interests of USO. While USO’s exposure under these indemnification provisions cannot be estimated, they are not expected to have a material impact on USO’s financial position.

Redemption Basket Obligation

In order to meet its investment objective and pay its contractual obligations described below, USO requires liquidity to redeem shares, which redemptions must be in blocks of 100,000 shares called “Redemption Baskets.” USO has to date satisfied this obligation by

paying from the cash or cash equivalents it holds or through the sale of its Treasuries in an amount proportionate to the number of shares being redeemed.

Contractual Obligations

USO’s primary contractual obligations are with USCF. In return for its services, USCF is entitled to a management fee calculated daily and paid monthly as a fixed percentage of USO’s NAV, currently 0.45% of NAV on its average daily total net assets.

USCF agreed to pay the start-up costs associated with the formation of USO, primarily its legal, accounting and other costs in connection with USCF’s registration with the CFTC as a CPO and the registration and listing of USO and its shares with the SEC, FINRA and NYSE Arca (formerly, AMEX), respectively. However, since USO’s initial offering of shares, offering costs incurred in connection with registering and listing additional shares of USO have been directly borne on an ongoing basis by USO, and not by USCF.

USCF pays the fees of the Marketing Agent as well as BNY Mellon’s fees for performing administrative, custodial, and transfer agency services. BNY Mellon’s fees for performing administrative services include those in connection with the preparation of USO’s financial statements and its SEC, NFA and CFTC reports. USCF and USO have also entered into a licensing agreement with the NYMEX pursuant to which USO and the Related Public Funds, other than BNO, USCI and CPER, pay a licensing fee to the NYMEX. USO also pays the fees and expenses associated with its tax accounting and reporting requirements.

In addition to USCF’s management fee, USO pays its brokerage fees (including fees to FCMs), OTC dealer spreads, any licensing fees for the use of intellectual property, and, subsequent to the initial offering, registration and other fees paid to the SEC, FINRA, or other regulatory agencies in connection with the offer and sale of shares, as well as legal, printing, accounting and other expenses associated therewith, and extraordinary expenses. The latter are expenses not incurred in the ordinary course of USO’s business, including expenses relating to the indemnification of any person against liabilities and obligations to the extent permitted by law and under the LP Agreement, the bringing or defending of actions in law or in equity or otherwise conducting litigation and incurring legal expenses and the settlement of claims and litigation. Commission payments to FCMs are on a contract-by-contract, or round turn, basis. USO also pays a portion of the fees and expenses of the independent directors of USCF. See Note 3 to the Notes to Financial Statements in Item 8 of this annual report on Form 10-K.

The parties cannot anticipate the amount of payments that will be required under these arrangements for future periods, as USO’s per share NAVs and trading levels to meet its investment objective will not be known until a future date. These agreements are effective for a specific term agreed upon by the parties with an option to renew, or, in some cases, are in effect for the duration of USO’s existence. Either party may terminate these agreements earlier for certain reasons described in the agreements.

As of December 31, 2025, USO’s portfolio held 13,180 Oil Futures Contracts traded on the NYMEX. As of December 31, 2025 USO did not hold any Oil Futures Contracts traded on the ICE Futures. For a list of USO’s current holdings, please see USO’s website at www.uscfinvestments.com.

The end of day portfolio disclosed on USO’s website would reflect any investments in Futures Contracts beyond the Benchmark Oil Futures Contract, and/or Other Oil-Related Investments, including any made in light of market conditions, regulatory requirements, risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants), liquidity requirements, or other factors. Independent of the USO website, USO may make available portfolio holdings information to Authorized Participants that reflects USO’s anticipated holdings.
