Prospectus Supplement

**John Hancock Variable Insurance Trust (the Trust)** <br>**Managed Volatility Growth Portfolio**

**Supplement dated December 11, 2025 to the current Summary Prospectus, as may be supplemented (the Summary Prospectus)**

The following information supplements and supersedes any information to the contrary relating to the funds contained in the Summary Prospectus.

At its meeting held on December 9-11, 2025, the Trust's Board of Trustees (the Board) approved changes to the fund's principal investment strategies and certain related changes. The fund's new principal investment strategies will be effective immediately; however, the fund's portfolio may not fully reflect the new principal investment strategies until the completion of a transition period on July 1, 2026 (the Effective Date).

In addition, at its meeting held on December 9-11, 2025, the Board approved a change to replace an additional benchmark with one that more closely correlates to the fund's investments, also effective on the Effective Date.

In connection with the change described above, as of the Effective Date, the paragraph below under the heading "Past performance" in the "Fund summary" section is amended and restated as follows:

The following information illustrates the variability of the fund's returns and provides some indication of the risks of investing in the fund by showing changes in the fund's performance from year to year and by showing how the fund's average annual returns compared with a broad-based securities market index. Past performance does not indicate future results. The Morningstar U.S. Moderately Aggressive Target Allocation Index and the fund's custom blended benchmark, the "John Hancock Lifestyle Growth Index," show how the fund's performance compares against the returns of similar investments. All figures assume dividend reinvestment. The performance information below does not reflect fees and expenses of any variable insurance contract which may use JHVIT as its underlying investment option. If such fees and expenses had been reflected, performance would be lower.

Additionally, as of the Effective Date, the "Average annual total returns" table for the fund under the heading "Past performance" in the "Fund summary" section is replaced in its entirety with the following:

---

| | | | |
|:---|:---|:---|:---|
| **Average annual total returns (%)—as of 12/31/2024** | **1 year** | **5 year** | **10 year** |
| **Series I** | 11.95 | &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;3.80 | &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;4.65 |
| **Series II** | 11.69 | &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;3.60 | &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;4.44 |

Prior to July 1, 2026, the fund's additional benchmark was the 49% Russell 3000 Index/21% MSCI EAFE Index/30% Bloomberg U.S. Aggregate Bond Index. Effective July 1, 2026, the fund's additional benchmark is the John Hancock Lifestyle Growth Index. The John Hancock Lifestyle Growth Index better reflects the universe of investment opportunities based on the fund's investment strategy. As of January 1, 2025, the John Hancock Lifestyle Growth Index comprises 41.6% of the S&P 500 Index, 15.7% of the MSCI World ex-USA Index, 11.6% of the Russell 2500 Index, 7.1% of the MSCI Emerging Markets Index, 4.0% of the John Hancock Real Asset Blended Index, 1.5% of the ICE BofA U.S. High Yield Index, 1.5% of the JPMorgan EMBI Global Index, 1.5% of the S&P/LSTA Leveraged Loan Index, 11.5% of the Bloomberg U.S. Aggregate Bond Index, 2.0% of the ICE BofA Long U.S. STRIPS Index, and 2.0% of the Bloomberg 1-5 Year TIPS Index.

Moreover, effective immediately, the disclosure under "Principal investment strategies" in the "Fund summary" section is revised and restated in its entirety as follows:

The Managed Volatility Growth Portfolio, except as otherwise described below, normally invests primarily in underlying funds that invest primarily in equity securities ("Equity Funds") and underlying funds that invest primarily in fixed-income securities ("Fixed-Income Funds"). The fund may also use certain risk management techniques to seek to manage the volatility of returns (i.e., standard deviation) and limit the magnitude of portfolio losses.

As described below, the fund may directly hold derivative instruments and collateral for these derivative instruments. The fund's economic exposure to equities and fixed-income securities may fluctuate due to its risk management strategy as noted below. The fund may employ a risk management strategy to attempt to manage the volatility of returns and limit the magnitude of portfolio losses. The risk management strategy may cause the

------

fund's economic exposure to equity securities, fixed-income securities and cash and cash equivalents (either directly or through investment in underlying funds or derivatives) to fluctuate, and during extreme market volatility, the fund's economic exposure to either equity or fixed-income securities could be reduced to 0% and its economic exposure to cash and cash equivalents could increase to 100%. The subadvisor normally will seek to limit the fund's exposure to equity securities (either directly or through investment in underlying funds or derivatives) to no more than 88% and normally will seek to reduce any equity exposure in excess of this amount as soon as practicable. However, the subadvisor may determine in light of market or economic conditions that the limit should be exceeded to achieve the fund's investment objective.

The fund seeks long term growth of capital while attempting to manage the volatility of returns and limit the magnitude of portfolio losses. The fund seeks to limit the volatility of returns to a range of 12.5% to 14.5% (as measured by annualized standard deviation of the fund's returns). However, during periods of prolonged low market volatility the actual volatility experienced by the fund may fall below the range due to maximum limits on equity and fixed-income exposures.

Volatility is a measure of the magnitude of up and down fluctuations in the fund's NAV over time as measured by the annualized standard deviation of its returns. Higher volatility generally indicates higher risk. The more a fund's returns vary from the fund's average return, the more volatile the fund and the higher the standard deviation. The purpose of managing the volatility of returns is to attempt to limit exposure to more volatile asset classes, including both equities and fixed-income asset classes, during periods of high volatility and protect the fund from losses during market declines. The fund also seeks to limit the magnitude of portfolio losses in order to limit exposure during market declines. There can be no assurance that the risk management strategy will be successful in managing the volatility of returns and limiting the magnitude of portfolio losses.

In seeking to manage the volatility of returns and limit the magnitude of portfolio losses, the fund may employ certain risk management techniques using derivative instruments and may reallocate assets between the underlying Equity and Fixed-Income Funds. These derivatives may be used to increase or decrease the fund's net equity exposure and will typically consist of stock index futures, but may also include stock index options, options on stock index futures, and stock index swaps. The fund may also employ risk management techniques using derivatives that may increase or decrease the fund's exposure to certain types of fixed-income securities. These instruments may include government bond futures, swaps, and credit default swaps. For more information about these derivative instruments in which the fund may invest, please see the "Hedging And Other Strategic Transactions" risk section in the Statement of Additional Information. Fund assets employed for its risk management strategy include not only derivative instruments but also fixed-income instruments. Because equity and fixed-income derivative instruments may be purchased with a fraction of the assets that would be needed to purchase the securities directly, the remainder of the assets used for the risk management strategy will be invested in a variety of fixed-income instruments. The fund may be required to hold cash or other liquid assets and post these assets with a broker as collateral to cover its obligation under the futures contracts. The fund's risk management strategy could limit the upside participation of the fund in strong, rising markets with high volatility and could underperform funds that do not use a risk management strategy.

The use of derivatives may be combined with asset allocation techniques. The timing and extent of these techniques will depend on several factors, including market movements. In general, when equity markets are more volatile or are declining, assets may be reallocated to Fixed-Income Funds, cash and/or cash equivalents, and short positions in equity derivative instruments. When equity markets rise, or if volatility is lower, assets may be reallocated to Equity Funds and stock index futures, options, and swaps. Similarly, if fixed-income markets are volatile or are declining, assets may be reallocated to Equity Funds, cash and cash equivalents, and short positions in fixed-income derivative instruments. Even in periods of low volatility, the subadvisor may continue to use risk management techniques to protect against sudden market movements, preserve gains after favorable market conditions, and reduce losses in adverse market conditions. Due to the leverage provided by derivatives, the notional value of the fund's derivative positions could exceed 100% of the fund's assets.

In determining when to employ risk management techniques and/or reallocate assets between Equity Funds and Fixed-Income Funds, the subadvisor may use quantitative models that use historical factors such as market movements, and historical changes in the NAV of the fund to make this determination.

The subadvisor selects the percentage level to be maintained in specific underlying Equity Funds and Fixed-Income Funds, and cash and cash equivalents and may from time to time change the allocation in specific underlying funds or rebalance the underlying funds. From time to time, a significant portion of the fund's underlying fixed income assets may be managed by an affiliated subadvisor. To maintain a target allocation in the underlying funds, daily cash flows for the fund may be directed to its underlying funds that most deviate from target.

The fund may invest in various Equity Funds that as a group hold a wide range of equity type securities. These include small-, mid- and large-capitalization stocks, domestic and foreign securities (including emerging market securities), and sector holdings such as utilities, science, and technology stocks. Each of these Equity Funds has its own investment strategy which, for example, may focus on growth stocks or value stocks or may employ a strategy combining growth and income stocks and/or may invest in derivatives such as options on securities and futures contracts. The fund may also invest in Fixed-Income Funds that as a group hold a wide range of fixed-income securities including investment grade and below-investment-grade debt securities with maturities that range from short to longer term. The Fixed-Income Funds collectively hold various types of debt instruments, such as corporate bonds, mortgage backed securities, U.S. and foreign government issued securities, domestic and international (including emerging markets) securities, inflation-protected securities, and bank loans. Equity Funds and Fixed-Income Funds may

------

include funds that employ a passive investment style (i.e., index funds and exchange-traded funds (ETFs)) and at times most of the fund's assets may be invested in index funds.

The fund may also invest in the securities of other investment companies including ETFs and may invest directly in other types of investments, such as equity and fixed-income securities including U.S. government securities, inflation-protected securities, closed-end funds, exchange-traded notes, and partnerships. See "Other Permitted Investments by the Funds of Funds." The fund may also engage in short selling. The fund may engage in active and frequent trading of portfolio securities and other instruments to achieve its primary investment strategies.

The fund bears its own expenses and, in addition, indirectly bears its proportionate share of the expenses of the underlying funds in which it invests.

*Use of Risk Management and Other Strategic Transactions.* In addition to the risk management techniques described above, the fund is authorized to use other investment strategies referred to under "Hedging And Other Strategic Transactions" risk section including, without limitation, investing in foreign currency forward contracts, futures contracts including stock index and foreign currency futures, swaps including interest rate swaps, stock index swaps and credit default swaps and options including stock index options and options on stock index futures, among others.

The manager considers environmental, social, and/or governance (ESG) factors, alongside other relevant factors, as part of its investment process. ESG factors may include, but are not limited to, matters regarding board diversity, climate change policies, and supply chain and human rights policies. The ESG characteristics utilized in the fund's investment process may change over time and one or more characteristics may not be relevant with respect to all issuers that are eligible fund investments. Because ESG factors are considered alongside other relevant factors, the manager may determine that an investment is appropriate notwithstanding its relative ESG characteristics.

Additionally, effective immediately, the following risk is added to the fund's "PRINCIPAL RISKS OF INVESTING IN THE FUNDS OF FUNDS" section under "Principal risks" in the "Fund summary" section:

**Inflation-protected securities risk.** Increases in real interest rates generally cause the price of inflation-protected debt securities to decrease.

Furthermore, effective immediately, the following risk is added to the fund's "PRINCIPAL RISKS OF INVESTING IN THE UNDERLYING FUNDS" section under "Principal risks" in the "Fund summary" section:

**Loan participations risk.** Participations and assignments involve special types of risks, including credit risk, interest-rate risk, counterparty risk, liquidity risk, risks associated with extended settlement, and the risks of being a lender.
