Dated June 8, 2026

As described in the Fund's prospectus, Fund shareholders are subject to an upside return cap that represents the maximum percentage return an investor can achieve from an investment in the Fund for a given buffer and Target Outcome Period. On June 18, 2026, the Fund's current Target Outcome Period will end, and a new Target Outcome Period will begin as of June 22, 2026. The new Target Outcome Period will end on June 18, 2027. While the actual caps and buffers will not be determined until the first day of the new Target Outcome Period, set forth below are the anticipated cap and buffer ranges for the Fund for the Target Outcome Period beginning on June 22, 2026. A supplement to the Fund's prospectus will be filed on June 22, 2026 that will include the actual cap and buffer for the new Target Outcome Period, which may be higher or lower than the anticipated cap and buffer ranges set forth below.
