Management's discussion of fund performance
The fund’s Class A shares gained 22.59% for the year ended April 30, 2026. That result compares with a 31.05% gain for the S&P 500 Index. For information on returns for additional periods, including the fund lifetime, please refer to .

What factors influenced results
U.S. equities reached record highs, supported by strong corporate earnings and accelerating AI‑driven investment, which helped offset volatility stemming from the conflict in Iran. Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.
Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.
Conversely, holdings within health care lagged. Returns from consumer staples and financials sectors, though positive, were lower than the overall portfolio’s return.

The fund’s Class 529-T shares gained 22.84% for the year ended April 30, 2026. That result compares with a 31.05% gain for the S&P 500 Index.
What factors influenced results
U.S. equities reached record highs, supported by strong corporate earnings and accelerating AI‑driven investment, which helped offset volatility stemming from the conflict in Iran. Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.
Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.
Conversely, holdings within health care lagged. Returns from consumer staples and financials sectors, though positive, were lower than the overall portfolio’s return.

The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.
Conversely, holdings within health care lagged. Returns from consumer staples and financials sectors, though positive, were lower than the overall portfolio’s return.

Changes in and disagreements with accountants
On July 3, 2025, PricewaterhouseCoopers (“PwC”) was dismissed and Deloitte & Touche LLP was appointed as the fund’s independent registered public accounting firm for the fiscal year ending April 30, 2026 audit. The change in the fund’s independent registered public accounting firm was approved by the fund’s board of trustees, including a majority of the independent trustees, upon recommendation of the audit committee, as part of a broader effort to update board oversight and fund operations. At no point during the fund’s fiscal years ended April 30, 2024 and April 30, 2025 and the subsequent interim period through July 3, 2025, were there any disagreements between management and PwC on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure.

What factors influenced results
U.S. equities reached record highs, supported by strong corporate earnings and accelerating AI‑driven investment, which helped offset volatility stemming from the conflict in Iran. Gains were broad-based, with growth sectors providing the highest returns. Energy stocks also advanced sharply as Middle East tensions drove oil prices higher and increased inflation concerns. U.S. economic growth remained solid although a softening labor market prompted the U.S. Federal Reserve (Fed) to deliver three 25‑basis‑point rate cuts during the fund’s fiscal year.
Within the fund, most sectors contributed to the portfolio, with information technology being particularly additive. Returns from the industrials, communication services and energy sectors were also positive. The utilities and real estate sectors also posted double-digit gains but had a less meaningful impact on portfolio results due to low relative exposure.
