Factors Affecting Performance [Text Block]
What factors influenced Fund performance during the reporting period?
During the 12-month reporting period ended April 30, 2026, the Fund’s performance relative to the FTSE Global Core Infrastructure 50/50 Index (Net) was affected by sector allocation and security selection. Market conditions reflected rising electricity demand driven by continued data center expansion, supporting the Fund’s positioning in utilities and other infrastructure assets that benefited from accelerating investment and earnings growth. Although geopolitical tensions and trade policy uncertainty contributed to market volatility, the Fund’s diversified exposure across utilities, transportation and midstream infrastructure, supported by inflation-linked and regulated revenue streams, further bolstered relative returns.
The following table outlines the key factors (securities, sectors, industries, market events and/or other characteristics) that materially affected the Fund’s performance during the reporting period.
Key Factor Summary Impact
Communications: Americas Positive stock selection, including an out-of-index position in data center owner Equinix, Inc., and underweight exposure to tower companies Contributed
Transportation: Continental Europe Strong selection among European toll road and airport stocks, particularly Ferrovial NV and Flughafen Zurich AG Contributed
Utilities: Americas Positive stock selection, particularly Constellation Energy Corp., The AES Corporation and Entergy Corp. Contributed
Midstream: Americas Positive stock selection undermined by underweight exposure to one of the best-performing sectors globally Detracted
Transportation: Americas Positive stock selection partially offset by underweight exposure to North American railroads Detracted

Factors Affecting Performance [Text Block]
What factors influenced Fund performance during the reporting period?
During the 12-month reporting period ended April 30, 2026, the Fund’s performance relative to the FTSE Global Core Infrastructure 50/50 Index (Net) was affected by sector allocation and security selection. Market conditions reflected rising electricity demand driven by continued data center expansion, supporting the Fund’s positioning in utilities and other infrastructure assets that benefited from accelerating investment and earnings growth. Although geopolitical tensions and trade policy uncertainty contributed to market volatility, the Fund’s diversified exposure across utilities, transportation and midstream infrastructure, supported by inflation-linked and regulated revenue streams, further bolstered relative returns.
The following table outlines the key factors (securities, sectors, industries, market events and/or other characteristics) that materially affected the Fund’s performance during the reporting period.
Key Factor Summary Impact
Communications: Americas Positive stock selection, including an out-of-index position in data center owner Equinix, Inc., and underweight exposure to tower companies Contributed
Transportation: Continental Europe Strong selection among European toll road and airport stocks, particularly Ferrovial NV and Flughafen Zurich AG Contributed
Utilities: Americas Positive stock selection, particularly Constellation Energy Corp., The AES Corporation and Entergy Corp. Contributed
Midstream: Americas Positive stock selection undermined by underweight exposure to one of the best-performing sectors globally Detracted
Transportation: Americas Positive stock selection partially offset by underweight exposure to North American railroads Detracted

What factors influenced Fund performance during the reporting period?
During the 12-month reporting period ended April 30, 2026, the Fund’s performance relative to the FTSE Nareit All Equity REITs Index was driven by strong sector allocation offset by a drag from negative stock selection. Sector allocation benefited from overweight exposure to health care and data centers, as well as an underweight allocation to the underperforming residential sector. Stock selection detracted from relative performance, primarily due to an overweight position in net lease gaming company VICI Properties Inc., partially offset by overweight exposure to senior housing companies Welltower Inc., American Healthcare REIT, Inc., and Janus Living, Inc.
The following table outlines the key factors (securities, sectors, industries, market events and/or other characteristics) that materially affected the Fund’s performance during the reporting period.

Factors Affecting Performance [Text Block]
What factors influenced Fund performance during the reporting period?
During the 12-month reporting period ended April 30, 2026, the Fund’s performance relative to the FTSE Nareit All Equity REITs Index was driven by strong sector allocation offset by a drag from negative stock selection. Sector allocation benefited from overweight exposure to health care and data centers, as well as an underweight allocation to the underperforming residential sector. Stock selection detracted from relative performance, primarily due to an overweight position in net lease gaming company VICI Properties Inc., partially offset by overweight exposure to senior housing companies Welltower Inc., American Healthcare REIT, Inc., and Janus Living, Inc.
The following table outlines the key factors (securities, sectors, industries, market events and/or other characteristics) that materially affected the Fund’s performance during the reporting period.
Key Factor Summary Impact
Health Care Sector Overweight exposure to an outperforming sector Contributed
Welltower Inc. Overweight exposure to an outperforming security Contributed
Residential Sector Underweight exposure to an underperforming sector Contributed
Vornado Realty Overweight exposure to an underperforming security Detracted
Hotel Sector Stock selection in the sector was a detractor Detracted

Fund Performance
The following graph compares the initial and subsequent account values at the end of each of the most recently completed 10 fiscal years of the Fund (or for the life of the Fund, if shorter). It assumes a $10,000 initial investment at the beginning of the first fiscal year in an appropriate, broad-based securities market index and other indexes, if applicable, for the same period and reflects the deduction of all sales charges, where applicable. Effective February 21, 2020, the Voya Real Estate Fund (the "Predecessor Fund") was reorganized into the Fund. As accounting successor to the Predecessor Fund, the Fund has assumed the Predecessor Fund’s historical performance. Therefore, the performance information shown below includes that of the Predecessor Fund, which had a different fee structure than the Fund.

Factors Affecting Performance [Text Block]
What factors influenced Fund performance during the reporting period?
During the 12-month reporting period ended April 30, 2026, the Fund’s performance relative to the internally maintained blend of indices that are taken into account when managing the Fund, as well as the Conservative Allocation Composite Index, was affected by various allocation and selection factors. Most notably, relative returns benefited from effective asset class positioning, specifically tactical exposure to convertible bonds and emerging market debt alongside an overweight in emerging market equities. An internal skew toward quality small-cap U.S. equities acted as a modest headwind.
The following table outlines the key factors (securities, sectors, industries, market events and/or other characteristics) that materially affected the Fund’s performance during the reporting period.
Key Factor Summary Impact
Internal benchmarking Benefited from granular management approach that included mid- and small-cap stocks, emerging-markets equities and high yield Contributed
Overweight in emerging market equities Bolstered particularly by ex-China exposure, with noteworthy gains from chip manufacturers (TSMC, Samsung, SK Hynix) Contributed
Off-benchmark exposure to convertible bonds Sensitivity to growth equities Contributed
Stock/bond blend A modest but persistent tilt favoring stocks over bonds Contributed
Quality An emphasis on quality (positive and relatively stable earnings) within small caps during a period in which unprofitable tech with high growth expectations led the market higher Detracted
Developed international exposure A brief tactical overweight in non-U.S. developed markets, across both large- and small-cap companies Detracted

Factors Affecting Performance [Text Block]
What factors influenced Fund performance during the reporting period?
During the 12-month reporting period ended April 30, 2026, the Fund’s performance relative to the internally maintained blend of indices that are taken into account when managing the Fund, as well as the Conservative Allocation Composite Index, was affected by various allocation and selection factors. Most notably, relative returns benefited from effective asset class positioning, specifically tactical exposure to convertible bonds and emerging market debt alongside an overweight in emerging market equities. An internal skew toward quality small-cap U.S. equities acted as a modest headwind.
The following table outlines the key factors (securities, sectors, industries, market events and/or other characteristics) that materially affected the Fund’s performance during the reporting period.
Key Factor Summary Impact
Internal benchmarking Benefited from granular management approach that included mid- and small-cap stocks, emerging-markets equities and high yield Contributed
Overweight in emerging market equities Bolstered particularly by ex-China exposure, with noteworthy gains from chip manufacturers (TSMC, Samsung, SK Hynix) Contributed
Off-benchmark exposure to convertible bonds Sensitivity to growth equities Contributed
Stock/bond blend A modest but persistent tilt favoring stocks over bonds Contributed
Quality An emphasis on quality (positive and relatively stable earnings) within small caps during a period in which unprofitable tech with high growth expectations led the market higher Detracted
Developed international exposure A brief tactical overweight in non-U.S. developed markets, across both large- and small-cap companies Detracted

5.
The Morningstar Global Moderately Conservative Allocation Category Average is representative of funds in allocation categories that seek to provide both income and capital appreciation by primarily investing in multiple asset classes, including stocks, bonds, and cash. These moderately conservative strategies prioritize the preservation of capital over appreciation. They typically expect volatility similar to a strategic equity exposure between 30% and 50%. Results are based on average total returns of similar funds with all dividends and capital gain distributions reinvested.

Factors Affecting Performance [Text Block]
What factors influenced Fund performance during the reporting period?
During the 12-month reporting period ended April 30, 2026, the Fund’s performance relative to the internally maintained blend of indices that are taken into account when managing the Fund, as well as the Equity Allocation Composite Index, was affected by various allocation and selection factors. Relative returns benefited from exposure to emerging-markets equities. A skew toward quality U.S. small-cap names and a brief tactical tilt favoring non-U.S. developed markets detracted.
The following table outlines the key factors (securities, sectors, industries, market events and/or other characteristics) that materially affected the Fund’s performance during the reporting period.
Key Factor Summary Impact
Internal benchmarking Benefited from granular management approach that included mid- and small-cap stocks, as well as emerging-markets equities Contributed
Overweight in emerging market equities Bolstered particularly by ex-China exposure, with noteworthy gains from chip manufacturers (TSMC, Samsung, SK Hynix) Contributed
Quality An emphasis on quality (positive and relatively stable earnings) within small caps during a period in which unprofitable tech with high growth expectations led the market higher Detracted
Developed international exposure A brief tactical overweight in non-U.S. developed markets, across both large- and small-cap companies Detracted

Factors Affecting Performance [Text Block]
What factors influenced Fund performance during the reporting period?
During the 12-month reporting period ended April 30, 2026, the Fund’s performance relative to the internally maintained blend of indices that are taken into account when managing the Fund, as well as the Moderate Allocation Composite Index, was affected by various allocation and selection factors. Most notably, relative returns benefited from effective asset class positioning, specifically tactical exposure to convertible bonds and emerging market debt alongside an overweight in emerging market equities. An internal skew toward quality small-cap U.S. equities acted as a modest headwind.
The following table outlines the key factors (securities, sectors, industries, market events and/or other characteristics) that materially affected the Fund’s performance during the reporting period.
Key Factor Summary Impact
Internal benchmarking Benefited from granular management approach that included mid- and small-cap stocks, emerging-markets equities and high yield Contributed
Overweight in emerging market equities Bolstered particularly by ex-China exposure, with noteworthy gains from chip manufacturers (TSMC, Samsung, SK Hynix) Contributed
Off-benchmark exposure to convertible bonds Sensitivity to growth equities Contributed
Stock/bond blend A modest but persistent tilt favoring stocks over bonds Contributed
Quality An emphasis on quality (positive and relatively stable earnings) within small caps during a period in which unprofitable tech with high growth expectations led the market higher Detracted
Developed international exposure A brief tactical overweight in non-U.S. developed markets, across both large- and small-cap companies Detracted

Factors Affecting Performance [Text Block]
What factors influenced Fund performance during the reporting period?
During the 12-month reporting period ended April 30, 2026, the Fund’s performance relative to the internally maintained blend of indices that are taken into account when managing the Fund, as well as the Moderate Allocation Composite Index, was affected by various allocation and selection factors. Most notably, relative returns benefited from effective asset class positioning, specifically tactical exposure to convertible bonds and emerging market debt alongside an overweight in emerging market equities. An internal skew toward quality small-cap U.S. equities acted as a modest headwind.
The following table outlines the key factors (securities, sectors, industries, market events and/or other characteristics) that materially affected the Fund’s performance during the reporting period.
Key Factor Summary Impact
Internal benchmarking Benefited from granular management approach that included mid- and small-cap stocks, emerging-markets equities and high yield Contributed
Overweight in emerging market equities Bolstered particularly by ex-China exposure, with noteworthy gains from chip manufacturers (TSMC, Samsung, SK Hynix) Contributed
Off-benchmark exposure to convertible bonds Sensitivity to growth equities Contributed
Stock/bond blend A modest but persistent tilt favoring stocks over bonds Contributed
Quality An emphasis on quality (positive and relatively stable earnings) within small caps during a period in which unprofitable tech with high growth expectations led the market higher Detracted
Developed international exposure A brief tactical overweight in non-U.S. developed markets, across both large- and small-cap companies Detracted

Factors Affecting Performance [Text Block]
What factors influenced Fund performance during the reporting period?
During the 12-month reporting period ended April 30, 2026, the Fund’s performance relative to the internally maintained blend of indices that are taken into account when managing the Fund, as well as the Growth Allocation Composite Index, was affected by various allocation and selection factors. Most notably, relative returns benefited from effective asset class positioning, specifically tactical exposure to convertible bonds and emerging market debt alongside an overweight in emerging market equities. An internal skew toward quality small-cap U.S. equities acted as a modest headwind.
The following table outlines the key factors (securities, sectors, industries, market events and/or other characteristics) that materially affected the Fund’s performance during the reporting period.
Key Factor Summary Impact
Internal benchmarking Benefited from granular management approach that included mid- and small-cap stocks, emerging-markets equities and high yield Contributed
Overweight in emerging market equities Bolstered particularly by ex-China exposure, with noteworthy gains from chip manufacturers (TSMC, Samsung, SK Hynix) Contributed
Off-benchmark exposure to convertible bonds Sensitivity to growth equities Contributed
