and each Fund's Summary Prospectus

(each, as previously supplemented)

Effective September 26, 2024, each Fund's name will be revised as set forth in the following table:

Current Fund Name	New Fund Name

Effective September 26, 2024, the ticker symbol for the Defiance S&P 500 Enhanced Options & 0DTE Income ETF will be changed from JEPY to WDTE.

Effective immediately, each Fund's principal investment strategy is supplemented to reflect the use of options that expire on the same date (ODTE). In particular,

●	The third sentence of the third paragraph is revised to read as follows: "This opportunity exists until the option's expiration date, which is typically the next day or the same day (0DTE)."

●

Under the heading "The Fund's Use of Index Option Contracts," the fifth sentence of the first paragraph is revised to read as follows: "The expiration dates at the time of purchase for the Fund's sold puts will range from same day expiration to a week." In addition, the last sentence of the third paragraph is revised to read as follows: "The Fund would be obligated to cash settle the put option the difference between the strike price and the actual level of the Index, multiplied by the contract multiplier (usually 100 for equity index options)."

●	Under the heading "Fund's Return Profile vs the Index," the last paragraph is revised to read as follows:

However, the Fund's notional exposure will drift during each trading day. The Fund will reallocate its portfolio either during the day's trading session (intraday) or at the end of each trading day. That is, the Fund will allow each day's options to expire and then settle them in cash before entering into new put options. At times, the Fund may close out existing options positions and enter into new ones intraday. By settling expiring options in cash either intraday or at the end of the day, the Fund can seek to reduce execution costs and minimize trading drift.

Effective immediately, each Fund's principal investment strategy is revised to reflect that it will seek to provide weekly distributions. As a result, all references in the prospectus and SAI to monthly distributions are hereby changed to weekly distributions.

Effective immediately, each Fund will seek a minimum daily income of 0.15%. All references in the prospectus to seeking a minimum daily income are revised accordingly.
