As a result of a series of mergers on May 6, 2024 (the "Mergers"), the Fund acquired all of the assets, subject to the liabilities, of First Trust Energy Income and Growth Fund, First Trust MLP and Energy Income Fund, First Trust New Opportunities MLP & Energy Fund and First Trust Energy Infrastructure Fund, each a closed-end investment management company. As a result of the Mergers, the Fund has assumed the performance history of First Trust Energy Infrastructure Fund (the "Predecessor Fund"), which had an inception date of September 27, 2011. As the Predecessor Fund and Fund have a number of differences, including investment policies and practices and that the Predecessor Fund is a closed-end fund which utilizes leverage while the Fund is an exchange-traded fund which does not utilize leverage, the Predecessor Fund's past performance is not indicative of how the Fund will, or is expected to, perform in the future. Accordingly, any Fund performance and historical returns shown that incorporates Predecessor Fund performance prior to May 6, 2024 is not indicative of the performance that the Fund would have generated.
