Expense information has been restated to reflect current contractual rates.

Voya Investments, LLC (the "Investment Adviser") is contractually obligated to limit expenses to 1.49%, 0.99%, 0.99%, 1.24%, and 1.39% for Class ADV, Class I, Class R6, Class S, and Class S2 shares, respectively, through May 1, 2028 (the "Expense Limitation Agreement"). The limitation does not extend to interest, taxes, other investment-related costs, leverage expenses, extraordinary expenses such as litigation or other expenses not incurred in the ordinary course of business, and expenses of any counsel or other persons or services retained by the Directors who are not "interested persons" as that term is defined by the Investment Company Act of 1940, as amended. Modification of the Expense Limitation Agreement requires written agreement signed by each of the parties and approval by the Portfolio's Board of Directors (the "Board"). The Expense Limitation Agreement shall terminate with respect to the Portfolio upon termination of the Portfolio's advisory agreement with the Investment Adviser, or it may be terminated by Voya Partners, Inc. (the "Company"), without payment of any penalty, upon written notice to the Investment Adviser at its principal place of business.

**Expense Example**

------

This Example is intended to help you compare the cost of investing in shares of the Portfolio with the costs of investing in other mutual funds. The Example does not reflect expenses and charges which are, or may be, imposed under your Variable Contract or Qualified Plan. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated. The Example also assumes that your investment had a 5% return each year and that the Portfolio's operating expenses remain the same. The Example reflects applicable expense limitation agreements and/or waivers in effect, if any, for the one-year period and the first two years of the time periods indicated. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

**Portfolio Turnover**

------

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio Operating Expenses or in the Expense Example, affect the Portfolio's performance.

During the most recent fiscal year, the Portfolio's portfolio turnover rate was 13% of the average value of its portfolio.

**Principal Investment Strategies**

The Portfolio is a diversified fund that, under normal circumstances, invests primarily in equity securities of U.S. small-sized growth companies. For this Portfolio, the sub-adviser (the "Sub-Adviser") defines small capitalization companies as those, at the time of purchase, with market capitalizations up to the largest market cap stock in the Russell 2000<sup>®</sup> Growth Index at reconstitution, or companies with market capitalizations up to $2.5 billion, whichever is larger. The Portfolio will not sell positions just because their market values have increased. Because of its long-term approach, the Portfolio could have a significant percentage of its assets invested in securities that have appreciated beyond their market capitalizations at the time of the Portfolio's investment.

The Portfolio may invest in American Depository Receipts, Global Depository Receipts, European Depository Receipts or directly in the securities of non-US issuers, provided that the aggregate amount of such investments does not exceed 35% of the portfolio's respective total assets at the time of purchase. Depositary receipts are receipts issued by a bank or a trust company reflecting ownership of underlying securities issued by foreign (non-U.S.) companies. The Portfolio may invest in real estate-related securities, including real estate investment trusts ("REITs").

The Portfolio may invest in other investment companies, including exchange-traded funds ("ETFs"), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder.

The Sub-Adviser seeks to invest in businesses it believes have significant opportunities for growth, sustainable competitive advantages, strong, exceptional management, and an attractive valuation. The Portfolio purchases stocks that the Sub-Adviser believes are undervalued relative to their businesses' long-term growth prospects, future cash flows and asset values. The Sub-Adviser seeks to invest in businesses before their long-term growth prospects are appreciated by other investors. The Portfolio may make significant investments in companies in which the Sub-Adviser has great conviction.

The Sub-Adviser may sell assets for a variety of reasons, including in response to a change in the Sub-Adviser's original investment considerations, to limit losses, to adjust the characteristics of the overall portfolio, or redeploy assets into different opportunities.

The Portfolio may lend portfolio securities on a short-term or long-term basis, up to 33 <sup>1</sup>∕3% of its total assets.

**Pending Merger** - On November 13, 2025, the Portfolio's Board of Directors approved a proposal to reorganize the Portfolio into Voya MidCap Opportunities Fund (a series of Voya Equity Trust), subject to approval by the Portfolio's shareholders. If approved, it is expected that the reorganization will take place on or about July 17, 2026 (the "Closing Date"). Prior to the Closing Date, a large portion of the Portfolio's assets may be placed in temporary investments. During such a time, the Portfolio may not be pursuing its investment objective and strategies. After the reorganization shareholders that hold shares of the Portfolio on the Closing Date will hold shares of Voya MidCap Opportunities Fund. For more information regarding Voya MidCap Opportunities Fund, please contact a Shareholder Services representative at 1-800-992-0180 or your financial professional.

VY<sup>®</sup> Baron Growth Portfolio

**Principal Risks**

You could lose money on an investment in the Portfolio. Any of the following risks, among others, could affect Portfolio performance or cause the Portfolio to lose money or to underperform market averages of other funds. The principal risks are presented in alphabetical order to facilitate readability, and their order does not imply that the realization of one risk is more likely to occur or have a greater adverse impact than another risk.

**Company:** The price of a company's stock could decline or underperform for many reasons, including, among others, poor management, financial problems, reduced demand for the company's goods or services, regulatory fines and judgments, or business challenges. If a company is unable to meet its financial obligations, declares bankruptcy, or becomes insolvent, its stock could become worthless.

**Currency:** To the extent that the Portfolio invests directly or indirectly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those foreign (non-U.S.) currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged by the Portfolio through foreign currency exchange transactions.

**Focused Investing:** To the extent that a Portfolio invests a substantial portion of its assets in securities of a particular industry, sector, market segment, or geographic area, the Portfolio may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters, affecting issuers in a particular industry, sector, market segment, or geographic area in which the Portfolio focuses its investments, and if securities of such industry, sector, market segment, or geographic area fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that has greater diversification.

• **Financials Sector:** Investments in the financials sector may be subject to credit risk, interest rate risk, and regulatory risk, among others. Banks and other financial institutions can be affected by such factors as downturns in the U.S. and foreign economies and general economic cycles, fiscal and monetary policy (including the effects of changes in interest rates), adverse developments in the real estate market, the deterioration or failure of other financial institutions, and changes in banking or securities regulations.

**Foreign (Non-U.S.) Investments:** Investing in foreign (non-U.S.) securities may result in the Portfolio experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due, in part, to: smaller markets; differing reporting, accounting, auditing and financial reporting standards and practices; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; and political changes or diplomatic developments, which may include the imposition of economic sanctions (or the threat of new or modified sanctions) or other measures by the U.S. or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region.

**Growth Investing:** Prices of growth-oriented stocks are more sensitive to investor perceptions of the issuer's growth potential and may fall quickly and significantly if investors suspect that actual growth may be less than expected. There is a risk that funds that invest in growth-oriented stocks may underperform other funds that invest more broadly. Growth-oriented stocks tend to be more volatile than value-oriented stocks, and may underperform the market as a whole over any given time period.

**Liquidity:** If a security is illiquid, the Portfolio might be unable to sell the security at a time when the Portfolio's manager might wish to sell, or at all. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, exposing the Portfolio to the risk that the prices at which it sells illiquid securities will be less than the prices at which they were valued when held by the Portfolio, which could cause the Portfolio to lose money. The prices of illiquid securities may be more volatile than more liquid securities, and the risks associated with illiquid securities may be greater in times of financial stress. Certain securities that are liquid when purchased may later become illiquid, particularly in times of overall economic distress or due to geopolitical events such as sanctions, trading halts, or wars. In addition, markets or securities may become illiquid quickly.

**Market:** The market values of securities will fluctuate, sometimes sharply and unpredictably, based on overall economic conditions, governmental actions or intervention, market disruptions caused by trade disputes or other factors, political developments, and other factors. Prices of equity securities tend to rise and fall more dramatically than those of debt instruments. Additionally, legislative, regulatory or tax policies or developments may adversely impact the investment techniques available to a manager, add to costs, and impair the ability of the Portfolio to achieve its investment objectives.

**Summary Prospectus**

VY<sup>®</sup> Baron Growth Portfolio

------

**Market Disruption and Geopolitical:** The Portfolio is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Due to the increasing interdependence among global economies and markets, conditions in one country, market, or region might adversely impact markets, issuers and/or foreign exchange rates in other countries, including the United States. Wars, terrorism, global health crises and pandemics, trade disputes, tariffs and other restrictions on trade or economic sanctions, rapid technological developments (such as artificial intelligence technologies), and other geopolitical events that have led, and may continue to lead, to increased market volatility and may have adverse short- or long-term effects on U.S. and global economies and markets, generally. For example, the COVID-19 pandemic resulted in significant market volatility, exchange suspensions and closures, declines in global financial markets, higher default rates, supply chain disruptions, and a substantial economic downturn in economies throughout the world. The economic impacts of COVID-19 have created a unique challenge for real estate markets. Many businesses have either partially or fully transitioned to a remote-working environment and this transition may negatively impact the occupancy rates of commercial real estate over time. Natural and environmental disasters and systemic market dislocations are also highly disruptive to economies and markets. Military action by Russia in Ukraine, the prolonged conflict between Hamas and Israel, the Iranian conflict that commenced in February 2026, and political upheaval in Venezuela have resulted, and may continue to result, in sanctions, market disruptions, declines in regional and global stock markets, unusual volatility in global commodity markets, and disruptions to energy production or transportation, including through key shipping routes, any of which could adversely affect the value of the Portfolio's investments, including beyond the Portfolio's direct exposure to issuers in the affected regions. The escalation or expansion of hostilities including the involvement of additional nations, could introduce further uncertainty and volatility in global energy, commodity, and financial markets. The extent and duration of these conflicts, related sanctions, and resulting market disruptions are impossible to predict but could be substantial. A number of U.S. domestic banks and foreign (non-U.S.) banks have experienced financial difficulties and, in some cases, failures. There can be no certainty that the actions taken by regulators to limit the effect of those financial difficulties and failures on other banks or other financial institutions or on the U.S. or foreign (non-U.S.) economies generally will be successful. It is possible that more banks or other financial institutions will experience financial difficulties or fail, which may affect adversely other U.S. or foreign (non-U.S.) financial institutions and economies. These events as well as other changes in foreign (non-U.S.) and domestic economic, social, and political conditions also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of the Portfolio's investments. Any of these occurrences could disrupt the operations of the Portfolio and of the Portfolio's service providers. Recent technological developments in, and the increasingly widespread use of, artificial intelligence, including machine learning technology and generative artificial intelligence ("AI"), may pose risks to the Portfolio. For instance, the economy may be significantly impacted by the advanced development and increased regulation of AI. As AI is used more widely, the profitability and growth of Portfolio holdings may be impacted, which could significantly impact the overall performance of the Portfolio. The legal and regulatory frameworks within which AI operates continue to rapidly evolve, and it is not possible to predict the full extent of current or future risks related thereto.

**Other Investment Companies:** The main risk of investing in other investment companies, including ETFs, is the risk that the value of an investment company's underlying investments might decrease. Shares of investment companies that are listed on an exchange may trade at a discount or premium from their net asset value. You will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the Portfolio's expenses. The investment policies of the other investment companies may not be the same as those of the Portfolio; as a result, an investment in the other investment companies may be subject to additional or different risks than those to which the Portfolio is typically subject. In addition, shares of ETFs may trade at a premium or discount to net asset value and are subject to secondary market trading risks. Secondary markets may be subject to irregular trading activity, wide bid/ask spreads, and extended trade settlement periods in times of market stress because market makers and authorized participants may step away from making a market in an ETF's shares, which could cause a material decline in the ETF's net asset value.

**Real Estate Companies and Real Estate Investment Trusts:** Investing in real estate companies and REITs may subject the Portfolio to risks similar to those associated with the direct ownership of real estate, including losses from casualty or condemnation, changes in local and general economic conditions, supply and demand, market interest rates, zoning laws, regulatory limitations on rents, property taxes, overbuilding, high foreclosure rates, and operating expenses in addition to terrorist attacks, wars, or other acts that destroy real property. In addition, REITs may also be affected by tax and regulatory requirements in that a REIT may not qualify for favorable tax treatment or regulatory exemptions. Investments in REITs are affected by the management skill of the REIT's sponsor. The Portfolio will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests.

**Summary Prospectus**

**Securities Lending:** Securities lending involves two primary risks: "investment risk" and "borrower default risk." When lending securities, the Portfolio will receive cash or U.S. government securities as collateral. Investment risk is the risk that the Portfolio will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Portfolio will lose money due to the failure of a borrower to return a borrowed security. Securities lending may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing the Portfolio to be more volatile. The use of leverage may increase expenses and increase the impact of the Portfolio's other risks.

**Small-Capitalization Company:** Investments in small-capitalization companies may involve greater risk than is customarily associated with larger, more established companies due to the greater business risks of a limited operating history, small size, limited markets and financial resources, narrow product lines, less management depth and more reliance on key personnel. The securities of small-capitalization companies are subject to liquidity risk as they are often traded over-the-counter and may not be traded in volumes typically seen on national securities exchanges.

*An investment in the Portfolio is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency*.

**Performance Information**

The following information is intended to help you understand the risks of investing in the Portfolio. The following bar chart shows the changes in the Portfolio's performance from year to year, and the table compares the Portfolio's performance to the performance of a broad-based securities market index and additional indices with investment characteristics similar to those of the Portfolio for the same period. In 2024, the Investment Adviser changed the Portfolio's primary benchmark from the Russell 2000<sup>®</sup> Growth Index to the Russell 3000<sup>®</sup> Index in accordance with changes to regulatory disclosure requirements. The Portfolio continues to use the Russell 2000<sup>®</sup> Growth Index as an additional benchmark that the Investment Adviser believes more closely reflects the Portfolio's principal investment strategies. The Portfolio's performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The bar chart shows the performance of the Portfolio's Class ADV shares. Performance for other share classes would differ to the extent they have differences in their fees and expenses. The Class R6 shares performance shown for the period prior to their inception date is the performance of Class I shares without adjustment for any differences in expenses between the two classes. If adjusted for such differences, returns would be different.

Performance shown in the bar chart and in the Average Annual Total Returns table does not include insurance-related charges imposed under a Variable Contract or expenses related to a Qualified Plan. If these charges or expenses were included, performance would be lower. Thus, you should not compare the Portfolio's performance directly with the performance information of other investment products without taking into account all insurance-related charges and expenses payable under your Variable Contract or Qualified Plan. The Portfolio's past performance is no guarantee of future results.

**Purchase and Sale of Portfolio Shares**

Shares of the Portfolio are not offered directly to the public. Purchase and sale of shares may be made only by separate accounts of insurance companies serving as investment options under Variable Contracts or by Qualified Plans, custodian accounts, and certain investment advisers and their affiliates, other investment companies, or permitted investors. Please refer to the prospectus for the appropriate insurance company separate account, investment company, or your plan documents for information on how to direct investments in, or sale from, an investment option corresponding to the Portfolio and any fees that may apply. Participating insurance companies and certain other designated organizations are authorized to receive purchase orders on the Portfolio's behalf.

**Tax Information**

Distributions made by the Portfolio to a Variable Contract or Qualified Plan, and exchanges and redemptions of Portfolio shares made by a Variable Contract or Qualified Plan, ordinarily do not cause the corresponding contract holder or plan participant to recognize income or gain for U.S. federal income tax purposes. See the Variable Contract prospectus or the governing documents of your Qualified Plan for information regarding the U.S. federal income tax treatment of the distributions to your Variable Contract or Qualified Plan and the holders of the contracts or plan participants.

**Payments to Broker-Dealers and Other Financial Intermediaries**

If you invest in the Portfolio through a Variable Contract issued by an insurance company or through a Qualified Plan that, in turn, was purchased or serviced through an insurance company, broker-dealer or other financial intermediary, the Portfolio and its Investment Adviser or distributor or their affiliates may: (1) make payments to the insurance company issuer of the Variable Contract or to the company servicing the Qualified Plan and (2) make payments to the insurance company, broker-dealer, or other financial intermediary. These payments may create a conflict of interest by: (1) influencing the insurance company
