Supplement dated October 16, 2025, to the Fund's Summary Prospectus, Prospectus

and Statement of Additional Information, each dated April 30, 2025

This supplement is intended to provide information to shareholders regarding changes to the name and principal investment strategies of the Gabelli Automation ETF (the "Fund"), as approved by the Board of Trustees (the "Board") of the Gabelli ETFs Trust.

Change in Name and Principal Investment Strategies

On or about December 15, 2025, the Fund's name will change to the Gabelli Global Technology Leaders ETF.

As of the same date, the Fund's Principal Investment Strategies section will be deleted in its entirely and replaced as follows:

The Fund is an actively managed exchange-traded fund ("ETF"). Under normal market conditions, the Fund invests at least 80% of the value of its net assets in the securities of companies principally engaged in the group of industries comprising the technology sector. As a fundamental policy, the Fund will concentrate (invest at least 25% of the value of its net assets) in the securities of companies principally engaged in the group of industries comprising the technology sector. The Fund invests primarily in common stocks of foreign and domestic small capitalization, mid capitalization, and large capitalization issuers. As a "global" fund, the Fund invests in securities of issuers, or related investments thereof, located in at least three countries, and at least 40% of the Fund's total net assets are invested in securities of non-U.S. issuers or related investments thereof. The Fund will favor investing in companies that the Adviser believes possess market leadership and competitive advantages. The Fund may invest in the equity securities of such companies, such as common stock, or preferred stock of such companies in accordance with the foregoing 80% policy. The Fund may also invest in foreign securities, including, but not limited to: (i) direct investments in securities of foreign issuers principally located in Japan, the United Kingdom, and Europe; and (ii) investments in American Depositary Receipts that represent indirect investments in securities of foreign issuers. The Fund may invest in companies without regard to market capitalization.

The Fund considers a company to be principally engaged in the group of industries comprising the technology sector if it devotes a significant portion of its assets to, or derives a significant portion of its revenues from the development, research, and/or distribution of technology and related goods and services. The Fund considers a company to be principally engaged in the group of industries comprising the technology sector if it devotes 50% of its assets to, or derives 50% of its revenues from, hardware, software and related services, data storage, and peripherals; communications services and equipment; semiconductors; and electronic equipment, instruments and components.

The Fund invests in equity securities of companies that the Adviser believes are leaders within their respective industries as demonstrated by the ability to deliver high relative returns on invested capital and proprietary technology, the proficiency to leverage technological expertise into a competitive advantage, and/or a proven track record of research and development resulting in new products, services, or technologies.

The Adviser's investment philosophy with respect to buying and selling equity securities is to identify assets that are selling in the public market at a discount to their private market value ("PMV"). The Adviser defines PMV as the value informed purchasers are willing to pay to acquire assets with similar characteristics. The Adviser considers factors such as price, earnings expectations, earnings and price histories, balance sheet characteristics, and perceived management skills. The Adviser also considers changes in economic and political outlooks as well as individual corporate developments. Further, the Adviser looks for a catalyst, something indigenous to the company, its industry or geographic positioning that may surface additional value, including, but not limited to, industry developments, regulatory changes, changes in management, sale or spin-off of a division, or the development of a profitable new business. The Adviser expects to seek to sell any Fund investments that lose their perceived value relative to other investments, which could occur because of, among other things, a security reaching a predetermined price target, a change to a company's fundamentals that make the risk/reward profile unattractive, or a need to improve the overall risk/reward profile of the Fund.

The Fund's investment objective, fees and expenses will not change as a result of the changes to the Fund as described above.
