Strategy. The Fund employs a passive management or indexing investment approach designed to track the performance of the Index. The Fund generally uses a representative sampling strategy to achieve its investment objective, meaning it generally will invest in a sample of the securities in the Index whose risk, return, and other characteristics resemble the risk, return, and other characteristics of the Index as a whole.

The Fund generally uses a representative sampling strategy to achieve its investment objective, meaning it generally will invest in a sample of the securities in the Index whose risk, return, and other characteristics resemble the risk, return, and other characteristics of the Index as a whole. WisdomTree, Inc. (WisdomTree), the index provider and the parent company of the Funds investment adviser, WisdomTree Asset Management, Inc. (WisdomTree Asset Management or the Adviser), designed the Index to provide exposure to equity securities of exchange-listed companies globally, which are primarily involved in cybersecurity and security-oriented technology that generate a meaningful part of their revenue from security protocols that prevent intrusion and attacks to systems, networks, applications, computers, and mobile devices (collectively, cybersecurity activities) and are experiencing revenue growth. The cybersecurity themes used as guidelines to determine if a company is primarily involved in cybersecurity activities are described in detail in the Additional Information About the Funds Investment Strategies section of the Prospectus. To be eligible for inclusion in the Index, a company must meet the following criteria as of the Index screening date: (i) derive at least 50% of their revenue from cybersecurity activities; (ii) revenue growth greater than or equal to 7% over the trailing three years for new constituents and revenue growth greater than or equal to 5% over the trailing three years for existing Index constituents; (iii) have a market capitalization of at least $300 million; and (iv) have a median daily dollar trading volume of at least $1 million for each of the preceding three months. The Index is reconstituted and rebalanced semi-annually. The index provider currently uses the Global Industry Classification Standard (GICS ), a widely recognized industry classification methodology developed by MSCI, Inc. and Standard & Poors Financial Services LLC, to identify the extent of the Indexs exposure to a sector or industry. A GICS sector typically is composed of multiple industries. Because the Fund seeks to track the Index, it is expected to have the same sector and industry exposure as the Index. While the Indexs and the Funds sector exposure may vary from time to time, as of September 30, 2025, the Index, and, therefore, the Fund, had significant exposure ( e.g. , approximately 15% or more of the Indexs total weight) to the Information Technology Sector. To the extent the Index is concentrated in the securities of companies assigned to a particular industry or group of industries, the Fund will seek to concentrate its investments ( i.e. , invest more than 25% of its assets) in such industry or group of industries to approximately the same extent as the Index. As of September 30, 2025, the Index, and, therefore, the Fund, concentrates in companies in the Software & Services Industry Group. As of September 30, 2025, the equity securities of companies that conduct their Primary Business Activities in the United States comprised a significant portion of the Funds holdings ( e.g. , approximately 15% or more), although the Funds geographic exposure may change from time to time.
