Investment Objective

The WisdomTree Bloomberg U.S. Dollar Bullish Fund (the "Fund") seeks to provide total returns, before fees and expenses, that exceed the performance of the Bloomberg Dollar Total Return Index (the "Index").

Fees and Expenses of the Fund

The following table describes the fees and expenses you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below. The fees are expressed as a percentage of the Fund's average net assets.

Shareholder Fees (fees paid directly from your investment)	None
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees	0.50%
Distribution and/or Service (12b-1) Fees	None
Other Expenses	0.00%
Acquired Fund Fees and Expenses	0.01%
Total Annual Fund Operating Expenses	0.51%1

1

The Total Annual Fund Operating Expenses in this fee table may not correlate to the expense ratios in the Fund's financial highlights and financial statements because the financial highlights and financial statements reflect only the operating expenses of the Fund and do not include Acquired Fund Fees and Expenses, which are fees and expenses incurred indirectly by the Fund through its investments in certain underlying investment companies.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes you invest $10,000 in the Fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year	3 Years	5 Years	10 Years
$ 52	$ 164	$ 285	$ 640

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Fund's Annual Fund Operating Expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 185% of the average value of its portfolio, excluding the value of portfolio securities received or delivered as a result of in-kind creations or redemptions of the Fund's capital shares.

Principal Investment Strategies of the Fund

The Fund is an actively managed exchange-traded fund ("ETF") that seeks to provide total returns, before fees and expenses, that exceed the performance of the Index. The Index is structured to potentially benefit as the U.S. dollar appreciates relative to a basket of global currencies. The Index tracks a long position in the U.S. dollar measured against a basket of developed and emerging market currencies which (i) have the highest liquidity in the currency markets and (ii) represent countries that make the largest contribution to trade flows with the United States. The Index also incorporates levels and differences in short-term interest rates between the U.S. and the countries (or regions) represented by the foreign currencies. To implement its methodology, the Index combines a basket of one-month currency forward contracts between the U.S. dollar and the individual constituent currencies of the Index and a U.S. dollar cash component invested at the 4-week Treasury Bill funding rate.

The Fund will seek exposure to both the U.S. dollar and global currencies held by the Index through investing, under normal circumstances, at least 80% of its assets in money market securities and other liquid securities, such as short-term investment grade government and corporate debt securities, combined with currency forward contracts in the individual constituent currencies of the Index (a currency forward contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract). If a sufficiently liquid futures contract on the Index or related index is later developed, the Fund may invest in such futures contract as a substitute for or in combination with forward contracts on the individual currencies. The Fund also may enter into repurchase agreements, which are transactions in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations. If, subsequent to an investment, the 80% requirement is no longer met, the Fund's future investments will be made in a manner that will bring the Fund into compliance with this policy.

The Fund's positioning for a stronger U.S. dollar through a mixture of securities and financial instruments is intended to provide a return reflective of the change in the value of the U.S. dollar relative to the basket of global currencies while incorporating differences in money market rates between the U.S. and the countries (or regions) represented by the foreign currencies. The Fund can also generate return from investments into high quality, short-term U.S. fixed income investments held in support of its currency positions. The Fund expects its holdings to represent between 8 to 20 currencies at any given time, with the euro expected to represent the largest exposure in the global basket of currencies. Since its inception, the Index has included exposures to approximately 10 to 12 currencies per year. The Fund, similar to the Index, is not designed to benefit if the value of the basket of global currencies appreciates relative to the U.S. dollar.

The Fund generally will maintain a weighted average portfolio maturity with respect to short-term investment grade government and corporate debt securities of two (2) years or less and money market securities of 180 days or less on average (not to exceed 18 months) and will not purchase any money market securities with a remaining maturity of more than 397 calendar days. The "average portfolio maturity" of the Fund will be the average of all current maturities of the individual securities in the Fund's portfolio. The Fund's actual portfolio duration may be longer or shorter depending on market conditions.

Principal Risks of Investing in the Fund

You can lose money on your investment in the Fund. While certain of the risks are prioritized in terms of their relevance to the Fund's investment strategies, most risks are presented in alphabetical order. This ordering approach is designed to both facilitate an investor's understanding of the Fund's risks and enable an investor to easily locate and compare risks among funds. Further, although the Fund invests primarily in money market securities, the Fund is NOT a money market fund and does NOT seek to maintain a stable net asset value per share ("NAV"). Each risk summarized below is considered a "principal risk" of investing in the Fund, regardless of the order in which it appears. Some or all of these risks may adversely affect the Fund's NAV, trading price, yield, total return and/or ability to meet its investment objective. For more information about the risks of investing in the Fund, see the sections in the Fund's Prospectus titled "Additional Principal Risk Information About the Funds" and "Additional Non-Principal Risk Information."

■	Currency Exchange Rate Risk. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund's investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may also change quickly, unpredictably, and without warning, and you may lose money.
■	Investment Risk. As with all investments, an investment in the Fund is subject to loss, including the possible loss of the entire principal amount of an investment, over short or long periods of time.

■

Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors, such as economic, financial or political events that impact the entire market, market segments, or specific issuers. The Fund's NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

■

Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, Fund shares may be bought and sold in the secondary market at market prices. The market prices of the Fund's shares in the secondary market generally differ from the Fund's daily NAV, and there may be times when the market price of the shares is more than the NAV (premium) or less than the NAV (discount). This risk is heightened in times of market volatility or periods of steep market declines. Because securities held by the Fund trade on, or have exposure to, foreign exchanges that are closed when the Fund's primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs. Additionally, in stressed market conditions, the market for the Fund's shares may become less liquid in response to deteriorating liquidity in the markets for the Fund's underlying portfolio holdings.

■	Active Management Risk. The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.

■

Capital Controls and Sanctions Risk. Economic conditions, such as volatile currency exchange rates and interest rates, political events, military action and other conditions may, without prior warning, lead to foreign government intervention (including intervention by the U.S. government with respect to foreign governments, economic sectors, foreign companies and related securities and interests) and the imposition of capital controls and/or sanctions, which may also include retaliatory actions of one government against another government, such as seizure of assets. Capital controls and/or sanctions include the prohibition of, or restrictions on, the ability to own or transfer currency, securities or other assets, which may potentially include derivative instruments related thereto. Capital controls and/or sanctions may also impact the ability of the Fund to buy, sell, transfer, receive, deliver or otherwise obtain exposure to, foreign securities or currency, negatively impact the value and/or liquidity of such instruments, adversely affect the trading market and price for shares of the Fund, and cause the Fund to decline in value.

■

Cash Redemption Risk. The Fund generally redeems shares for cash or otherwise includes cash as part of its redemption proceeds. The Fund may be required to sell or unwind its portfolio investments to obtain the cash needed to pay out redemption proceeds. This may cause the Fund to recognize capital gains that it might not have recognized if it had satisfied such redemption requests with securities held by the Fund (i.e., redeemed its shares in kind). As a result, the Fund may pay out higher annual capital gains distributions than a fund that redeems its shares in kind.

■

Counterparty and Issuer Credit Risk. As a result of its financial condition, the issuer of a debt security or other instrument, or the counterparty to a derivative or other contract, may default, become unable to pay interest or principal due or otherwise fail to honor its obligations or be perceived (whether by market participants, rating agencies, pricing services or otherwise) as being in such situations. The value of an investment in the Fund may change quickly and without warning in response to issuer or counterparty defaults, changes in the credit ratings of the Fund's portfolio investments and/or perceptions related thereto.

■

Cybersecurity Risk. The Fund and its service providers may be susceptible to operational and information security risks resulting from a breach in cybersecurity, including cyber-attacks. A breach in cybersecurity, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund's operational capacity, loss of proprietary information, theft or corruption of data, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund's third-party service providers, market makers, institutional investors authorized to purchase and redeem shares directly from the Fund (i.e., Authorized Participants), or the issuers of securities in which the Fund invests may subject the Fund to many of the same risks associated with direct cybersecurity breaches.

■

Derivatives Risk. Derivatives are financial instruments that derive their performance from an underlying reference asset, such as a commodity, index, interest rate, or inflation rate. Generally, derivatives are sophisticated investments that may pose risks that are different from or greater than those posed by investing directly in the underlying reference asset. For example, the return on a derivative instrument may not correlate with that of its underlying reference asset, and minimal requisite initial investments necessary to purchase derivatives positions may expose the Fund to losses in excess of those amounts. Derivatives also can be volatile and may be less liquid than other investments. As a result, the value of an investment in the Fund may change

quickly and without warning and you may lose money. The Fund expects to use forward currency contracts and futures contracts to implement its principal investment strategies. The successful use of forward currency contracts, in particular, depends in large part on the adviser's and the sub-adviser's ability to predict movements in the prices of relevant currencies, fluctuations in relevant markets, and movements in interest rates. Other risks specific to these types of derivatives instruments, as well as other risks of derivatives, generally, such as counterparty and issuer credit risk, interest rate risk, market risk, and issuer-specific risk, are described in greater detail elsewhere in the Fund's Prospectus.

■

Emerging Markets Risk. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Fund shares and cause the Fund to decline in value.

■

Foreign Securities Risk. Investments in non-U.S. securities involve political, regulatory, and economic risks that may not be present in investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to currency fluctuations, political or economic instability, or geographic events that adversely impact issuers of foreign securities. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These additional risks may make investments in the Fund more volatile and potentially less liquid than other types of investments. These risks may be heightened to the extent the Fund invests in companies domiciled in or otherwise tied to developing or emerging market countries.

■	Geographic Investment Risk. To the extent the Fund invests a significant portion of its assets in securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region.

■

Geopolitical Risk. Some countries and regions in which the Fund invests have and may continue to experience security concerns, war, threats of war, aggression and/or conflict, terrorism, economic uncertainty, sanctions or the threat of sanctions, natural and environmental disasters, the spread of infectious illness, widespread disease or other public health issues and/or systemic market dislocations that lead to increased short-term market volatility, have adverse long-term effects on the U.S. and world economies, and disrupt the orderly functioning of securities markets generally, which may negatively impact the Fund's investments.

■

Interest Rate Risk. Interest rate risk is the risk that fixed income securities will decline in value because of an increase in interest rates and changes to other factors, such as perception of an issuer's creditworthiness. Interest rates may change suddenly or unexpectedly and have unpredictable impacts on the financial markets and the Fund's investments. To the extent that the Fund holds fixed income securities with longer durations, such securities generally are subject to greater interest rate risk.

■	Issuer-Specific Risk. Issuer-specific events, including changes in the actual or perceived financial condition of an issuer, can have a negative impact on the value of the Fund.

■

Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers, and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.

■

Portfolio Turnover Risk. The Fund's investment strategy may result in a high portfolio turnover rate. Higher portfolio turnover may result in the Fund paying higher transaction costs and the distribution of additional capital gains, which may generate greater tax liabilities for shareholders who hold the shares in taxable accounts. Increased transaction costs and distributions of capital gains may negatively affect the Fund's performance.

■

Repurchase Agreement Risk. The Fund's investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.

■	Sovereign Debt Risk. The debt securities issued by sovereign entities may decline as a result of default or other adverse credit event resulting from a sovereign debtor's unwillingness or inability to repay principal and pay

interest in a timely manner, which may be affected by a variety of factors, including its cash flows, the extent of its reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the sovereign debtor's policy toward international lenders, and the political constraints to which a sovereign debtor may be subject. The risk associated with sovereign debt is heightened with respect to emerging market issuers.

■

U.S. Government Securities Risk. U.S. government securities may or may not be backed by the full faith and credit of the U.S. government. U.S. government securities are subject to the risks associated with fixed income and debt securities, particularly interest rate risk and credit risk. In addition, U.S. government securities not backed by the full faith and credit of the U.S. government involve credit risk that is greater than other types of U.S. government securities.

Fund Performance

Historical Fund performance, which varies over time, can provide an indication of the risks of investing in the Fund. The bar chart below shows the annual total returns of the Fund for each full calendar year for the past 10 years. The table that follows the bar chart shows the Fund's average annual total returns, both before and after taxes. This table also shows how the Fund's performance compares to that of the Index, a broad-based securities market index intended to represent the global currency market. Performance also is shown for the Bloomberg Dollar Spot Index, which more closely represents the investment exposure sought by the Fund. Index returns do not reflect deductions for fees, expenses, or taxes. All returns assume reinvestment of dividends and distributions. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information for the Fund is available online on the Fund's website at www.wisdomtree.com/investments.

The Fund's year-to-date total return as of September 30, 2025 was (4.66)%.

Best and Worst Quarter Returns (for the periods reflected in the bar chart above)

	Return	Quarter/Year
Highest Return	8.50%	4Q/2024
Lowest Return	(5.68)%	4Q/2022

After-tax returns are calculated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown and are not relevant if you hold your shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. In some cases, the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.

Average Annual Total Returns for the periods ending December 31, 2024

WisdomTree Bloomberg U.S. Dollar Bullish Fund	1 Year	5 Years	10 Years
Return Before Taxes Based on NAV	14.46%	4.52%	3.18%
Return After Taxes on Distributions	12.67%	3.08%	2.12%
Return After Taxes on Distributions and Sale of Fund Shares	8.55%	2.91%	2.06%
Bloomberg Dollar Spot Index (Reflects no deduction for fees, expenses or taxes)	7.98%	2.02%	1.48%
Bloomberg Dollar Total Return Index (Reflects no deduction for fees, expenses or taxes)	15.03%	4.79%	3.28%

Management

Investment Adviser and Sub-Adviser

WisdomTree Asset Management, Inc. ("WisdomTree Asset Management" or the "Adviser") serves as investment adviser to the Fund. Mellon Investments Corporation (the "Sub-Adviser") serves as the investment sub-adviser to the Fund.

Portfolio Managers

The Fund is managed by the Sub-Adviser's Fixed Income portfolio management team. The individual members of the team jointly and primarily responsible for the day-to-day management of the Fund's portfolio are identified below.

Marlene Walker-Smith, a Senior Director and Chief Investment Officer, has been a portfolio manager of the Fund since June 2025.

David Nieman, Vice President and Portfolio Manager, has been a portfolio manager of the Fund since November 2020.

Gregg Lee, CFA, Senior Vice President and Senior Portfolio Manager, has been a portfolio manager of the Fund since January 2021.

William Newton, CFA, Vice President, Portfolio Manager, has been a portfolio manager of the Fund since January 2024.

Bryan Steele, Senior Vice President and Senior Portfolio Manager, Fixed Income, has been a portfolio manager of the Fund since May 2026.

Buying and Selling Fund Shares

The Fund is an ETF. This means that individual shares of the Fund are listed for trading on a national securities exchange, currently NYSE Arca, and may only be purchased and sold in the secondary market through a broker-dealer at market prices. Because Fund shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (premium) or less than NAV (discount). In addition, an investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares (bid) and the lowest price a seller is willing to accept for shares (ask) when buying and selling shares in the secondary market (the "bid/ask spread"). Recent information regarding the Fund, including its NAV, market price, premiums and discounts, and bid/ask spreads, is available on the Fund's website at www.wisdomtree.com/investments.

The Fund issues and redeems shares at NAV only in large blocks of shares ("Creation Units"), which only certain institutions or large investors (typically market makers or other broker-dealers) may purchase or redeem. The Fund issues and redeems Creation Units in exchange for a portfolio of securities and/or U.S. cash.

Tax Information

The Fund intends to make distributions that may be taxed as ordinary income or capital gains.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank) (an "Intermediary"), WisdomTree Asset Management or its affiliates may pay Intermediaries for certain activities related to the Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange-traded products, including the Fund, or for other activities, such as marketing, educational training or other initiatives related to the sale or promotion of Fund shares. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Any such arrangements do not result in increased Fund expenses. Ask your salesperson or visit the Intermediary's website for more information.
