Factors Affecting Performance [Text Block]

How did the Fund perform last year and what affected its performance?

Class A shares of the Fund returned 8.63% (unadjusted for sales charges) for the period ended July 31, 2026. The Fund's broad-based index, the Russell 1000^® Index, returned 18.94% for the same period, while the Fund's additional, more narrowly based index, the Russell 1000^® Growth Index, returned 8.03%.

Stock selection was the primary driver of the Fund’s performance relative to the Russell 1000^® Growth Index. The Fund produced the best results in the industrials sector, led by its holding in Bloom Energy Corp. (0.8%). The company’s solid oxide fuel cells, which provide on-site electricity, have seen rising demand due to the need for off-grid solutions for data centers. Vertiv Holdings Co. (1.6%), Modine Manufacturing Co. (1.4%), and Comfort Systems USA, Inc. (1.3%), all of which make and install products used in data centers, were also top contributors in both the sector and the Fund as a whole.

The Fund also outperformed in information technology, with all of the advantage coming from a position in Micron Technology, Inc. (1.1%). The company benefited as strong demand from the AI infrastructure buildout helped fuel rising prices for its memory chips. A zero weighting in Oracle Corp. further helped relative performance, as the stock lagged its sector peers by a wide margin. Guardant Health, Inc. (1.4%), which generated robust growth behind strength in its blood-based oncology diagnostics testing business, was the top contributor in the portfolio as a whole. Exact Sciences Corp.,* which was taken over at a premium, was an additional contributor of note.

On the negative side, the Fund underperformed in the real estate sector due to a position in the analytics and information provider CoStar Group, Inc.* The company experienced weakness in its Homes.com unit and was pressured by competitive threats, causing it to cut its guidance. Holdings in a number of software companies — including ServiceNow, Inc. (1.3%), Atlassian Corp.,* and Snowflake, Inc.* — also hurt results amid concerns that the broader industry would face headwinds from AI. An underweight in Apple, Inc. (8.0%) and a zero weighting in Advanced Micro Devices, Inc. further weighed on relative performance.

Percentages in parentheses are based on the Fund’s net assets as of July 31, 2026.

* Not held at July 31, 2026.
