Direxion Shares ETF Trust – Direxion MU Defined Income Boost ETF is a non-diversified, non-leveraged exchange-traded fund that seeks daily investment results, before fees and expenses, corresponding to the performance of the Cboe MU Defined Income Index. The Fund provides income-oriented exposure linked to Micron Technology, Inc. common stock by obtaining exposure to a rules-based index strategy that writes weekly out-of-the-money call options on Micron Technology shares and employs daily delta hedging through long positions in the underlying security; it seeks to generate option-premium income while retaining partial participation in Micron Technology share-price movements. The Fund targets an annualized distribution yield of 20%, as set by Cboe Global Indices, LLC, and intends to make distributions twice monthly; distribution amounts and character, including potential return of capital, are not guaranteed. Its investment instruments may include swaps, options-related exposures, Micron Technology shares, cash and cash-management investments, and other assets used to replicate the Index’s performance. The Fund primarily serves investors seeking an exchange-traded, income-focused implementation of a single-stock options strategy within the information technology and semiconductor sectors. Direxion MU Defined Income Boost ETF commenced operations on July 29, 2026, trades under the ticker MUIB, and is offered by Direxion Shares ETF Trust; Rafferty Asset Management, LLC serves as investment adviser and ALPS Distributors, Inc. serves as distributor. The Fund has a gross expense ratio of 0.99% and a net expense ratio of 0.97%, with an operating-expense limitation arrangement in effect through September 1, 2027. The Fund’s principal office is in the United States.
