Factors Affecting Performance [Text Block]

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

Class A shares of the Fund returned 8.83% (unadjusted for sales charges) for the period ended September 30, 2025. The Fund's broad-based index, the Russell 1000^® Index, returned 17.75% for the same period, while the Fund's additional, more narrowly based index, the Russell 1000^® Value Index, returned 9.44%.

Stock selection contributed to the Fund’s performance relative to the Russell 1000^® Value Index, while sector allocations detracted. We produced the strongest results in financials, where Synchrony Financial (2.6%) was the leading contributor thanks to better-than-expected earnings. Holdings in State Street Corp. (2.6%) and Discover Financial Services* helped performance, as well. The Fund further benefited from stock selection in communication services, where shares of Fox Corp. (3.6%) rallied on the strength of its strong affiliate fees and rising revenues. Warner Bros. Discovery, Inc. (2.4%), which gained significantly late in the period on expectations that the company would be taken over, also aided results. Overweight positions in Meta Platforms, Inc. (0.6%) and Google parent Alphabet, Inc. (3.6%), both of which participated in the rally in mega-cap, technology-related stocks, were additional contributors of note. Positioning in the consumer discretionary sector also added value due in large part to holdings in Boyd Gaming Corp. (2.6%) and the luxury brand company Tapestry, Inc. (0.3%).

On the other hand, the Fund’s holdings in information technology lagged the broader sector by a wide margin. Cognizant Technology Solutions, Inc. (4.6%), which was seen as being a potential victim of the growth in artificial intelligence, was a notable laggard. We were also hurt by having an average overweight in Apple, Inc.,* as the stock declined in the first half of the period on concerns about weaker sales growth in China. Consumer staples was another area of underperformance, largely as a result of downturns in spirits producers and packaged food companies. Both categories trailed the sector and the broader market on worries about slowing sales. Positioning in energy also hurt results, primarily due to a downturn in the pipeline company ONEOK, Inc. (2.3%).

With respect to sector allocation, the majority of the shortfall came from an underweight in financials and an overweight in healthcare. An overweight in the outperforming communication services sector contributed positively.

Percentages in parentheses are based on the Fund’s net assets as of September 30, 2025.
