Investment Objective

The WisdomTree U.S. Efficient Core Fund (the "Fund") seeks total return.

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	0.20%
Distribution and/or Service (12b-1) Fees	None
Other Expenses	0.00%
Total Annual Fund Operating Expenses	0.20%

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
$ 20	$ 64	$ 113	$ 255

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 15% 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 actively managed using a model-based approach. The Fund seeks to achieve its investment objective by investing in large-capitalization U.S. equity securities and U.S. Treasury futures contracts.

The Fund invests in a representative basket of U.S. equity securities of large-capitalization companies generally weighted by market capitalization. Under normal circumstances, the Fund invests approximately 90% of its net assets in U.S. equity securities.

The remainder of the net assets, which WisdomTree Asset Management, Inc., the Fund's investment adviser ("WisdomTree Asset Management" or the "Adviser"), expects to be in cash and cash equivalents, will serve as collateral for U.S. Treasury futures contracts of varying maturities ranging from 2 to 30 years, which are selected to achieve a target duration of 3 to 8 years. Duration is a measure used to determine the sensitivity of a portfolio to changes in interest rates with a longer duration portfolio being more sensitive to changes in interest rates. Under normal circumstances, the aggregate U.S. Treasury futures contracts positions will represent a notional exposure (i.e., the total underlying amount of exposure created by a derivatives trade) of approximately 60% of the Fund's net assets. The notional exposure of a futures contract is calculated by multiplying the size of the futures contract by the market price for future delivery of the underlying U.S. Treasuries. The Adviser expects that the level of interest rate risk offered by the weighted positions in the U.S. Treasury futures contracts will be set and maintained at risk levels consistent with intermediate term fixed income securities. It is anticipated that the U.S. Treasury futures contracts will be rolled as they near expiry into new contracts, with the size of the futures positions at different maturity points adjusted to maintain the desired interest rate risk exposure.

The Fund's portfolio will be rebalanced quarterly to implement the results of the model. As a result, between quarterly rebalances, the Fund's allocations to U.S. equity securities and U.S. Treasury futures contracts may vary from the targeted 90%/60% allocations, and the targeted duration of and level of interest rate risk associated with the fixed income portion of the Fund may vary from their respective targets stated herein. To the extent exposure of the equity and fixed income portions of the Fund deviates from the targeted 90% equity and 60% U.S. Treasury futures contracts allocations noted above by 5% or greater, it is anticipated that the Fund will be rebalanced intra-quarter to more closely align its portfolio with the target allocations.

As of September 30, 2025, companies in the Information Technology Sector comprised a significant portion (e.g., approximately 15% or more) of the Fund's assets; however, the Fund's sector exposure may change from time to time.

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. 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 net asset value per share ("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."

■	Derivatives Risk. Derivatives are financial instruments that derive their performance from an underlying reference asset, such as a treasury security. 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 U.S. Treasury futures contracts to implement its principal investment strategy. A bond futures contract, such as a U.S. Treasury future, is an exchange-traded contract that provides for the future purchase or sale of the reference asset, at a specified price set at the time of contract. U.S. Treasury futures contracts are subject to the risk of imperfect correlation between the movements in the price of the futures contract and the underlying U.S. Treasury security.
■	Leveraging Risk. Certain transactions of the Fund, such as the use of derivative instruments, will give rise to leverage, magnifying gains and losses and causing the Fund to be more volatile than if it had not been leveraged. This means that leverage entails a heightened risk of loss.
■	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 exchange-traded funds ("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. 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.

■

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.

■

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.

■	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.

Investments in the United States
The economic, political, regulatory and other events and conditions that affect issuers and investments in the United States differ significantly from those associated with other countries and regions. For example, routine political events, such as a presidential election, can have a significant effect on the U.S. markets and lead to periods of increased volatility. U.S. financial markets also have become increasingly globalized, hosting participants from all over the world and on a more macro level, becoming more tightly integrated with financial markets around the world. As a result, U.S. financial markets are also increasingly vulnerable to the risks that may affect non-U.S. financial markets. Any event or condition that affects the U.S. economy, whether originating from within or outside of the United States, may have an adverse effect on the Fund's investments in the United States and thus, the Fund's performance.

■

Geopolitical Risk. The United States has 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.

■

Information Technology Sector Risk. The Fund currently invests a significant portion of its assets in the Information Technology Sector, and therefore, the Fund's performance could be negatively impacted by events affecting this sector. The Information Technology Sector includes, for example, companies that offer software and information technology services, manufacturers and distributors of technology hardware and equipment such as communications equipment, cellular phones, computers and peripherals, electronic equipment and

related instruments, and semiconductors and related equipment and materials. This sector can be significantly affected by, among other things, the supply and demand for specific products and services, the pace of technological development, and government regulation.

■

Interest Rate Risk. Interest rate risk is the risk that fixed income securities, and financial instruments related to 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. For example, the price of a security with an eight-year duration would be expected to drop by approximately 8% in response to a 1% increase in interest rates.

■	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.

■

Large-Capitalization Investing Risk. The Fund invests primarily in the securities of large-capitalization companies. As a result, the Fund's performance may be adversely affected if securities of these companies underperform securities of smaller capitalization companies or the market as a whole. Large-capitalization companies may adapt more slowly to new competitive challenges and be subject to slower growth during times of economic expansion.

■

Models and Data Risk. The Fund uses an investment model to implement its investment strategy. The Fund is subject to the risk that the investment model may not perform as intended, including because the model may not adequately take into consideration certain factors relevant to the Fund's investment strategy, investments, or the market environment, contains design flaws or incorporates faulty assumptions, or is informed by inaccurate or incomplete data. Errors in the data, assumptions and/or the design of the model may occur from time to time and may not be identified and/or corrected by the Sub-Adviser (defined below) or the Adviser for a significant period or at all, which may magnify the adverse effect on the Fund of any investment decisions made in reliance on the erroneous model results. Any of these circumstances may lead to investment decisions or the inclusion or exclusion of securities that adversely affect 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.

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 since the Fund commenced operations. 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 S&P 500^® Index, a broad-based securities market index intended to represent the overall domestic equity market. Performance is also shown for the 60% S&P 500^® Index / 40% Bloomberg U.S. Aggregate Index Composite, 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 16.13%.

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

	Return	Quarter/Year
Highest Return	19.31%	2Q/2020
Lowest Return	(17.50)%	2Q/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 U.S. Efficient Core Fund	1 Year	5 Years	Since Inception August 2, 2018
Return Before Taxes Based on NAV	19.76%	10.87%	11.58%
Return After Taxes on Distributions	19.41%	10.57%	11.25%
Return After Taxes on Distributions and Sale of Fund Shares	11.90%	8.60%	9.29%
60% S&P 500® Index / 40% Bloomberg U.S. Aggregate Index Composite (Reflects no deduction for fees, expenses or taxes)	15.31%	8.45%	8.86%
S&P 500® Index (Reflects no deduction for fees, expenses or taxes)	25.02%	14.53%	13.99%

Management

Investment Adviser and Sub-Adviser

WisdomTree Asset Management 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 Equity Index Strategies 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 October 2020.

David France, CFA, a Senior Vice President, Senior Portfolio Manager and Team Manager, has been a portfolio manager of the Fund since June 2021.

Todd Frysinger, CFA, a Senior Vice President, Senior Portfolio Manager and Team Manager, has been a portfolio manager of the Fund since June 2021.

Vlasta Sheremeta, CFA, a Senior Vice President, Senior Portfolio Manager and Team Manager, has been a portfolio manager of the Fund since June 2021.

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, Inc. (the "Listing Exchange"), 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, qualified dividend 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.
