Investment Objective

Growth of capital.

Fees and Expenses of the Portfolio

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Portfolio. The table and the Example below do not reflect the fees, expenses or withdrawal charges imposed by your variable life insurance policy or variable annuity contract (the “Contract”). If Contract expenses were reflected, the fees and expenses in the table and Example would be higher. See the Contract prospectus for a description of those fees, expenses and charges.

Shareholder Fees

(fees paid directly from your investment)—

None

Annual Portfolio Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
	Class A	Class B
Management Fee	0.07%	0.07%
Distribution and/or Service (12b-1) Fees	None	0.25%
Other Expenses	0.01%	0.01%
Acquired Fund Fees and Expenses (Underlying Portfolio Fees and Expenses)	0.65%	0.65%
Total Annual Portfolio Operating Expenses	0.73%	0.98%

Example

The following Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same. Although

your actual costs may be higher or lower, based on these assumptions, your costs would be:

	1 Year	3 Years	5 Years	10 Years
Class A	$75	$233	$406	$906
Class B	$100	$312	$542	$1,201

Portfolio Turnover

The Portfolio, which operates as a fund of funds, does not pay transaction costs when it buys and sells shares of the investment companies in which the Portfolio invests (the “Underlying Portfolios”) (or “turns over” its portfolio). An Underlying Portfolio pays transaction costs, such as commissions, when it turns over its portfolio, and a higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual portfolio operating expenses or in the Example, affect the performance of both the Underlying Portfolios and the Portfolio. During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 7% of the average value of its portfolio. Some of the Underlying Portfolios, however, may have portfolio turnover rates as high as 100% or more.

Principal Investment Strategies

The Portfolio seeks to achieve its objective by investing substantially all of its assets in Class A shares of the Underlying Portfolios, which are portfolios of Brighthouse Funds Trust I (the “Trust”) and Brighthouse Funds Trust II (“Trust II”). The Portfolio has a target allocation between the broad asset classes of equity and fixed income. Brighthouse Investment Advisers, LLC (“BIA” or “Adviser”), the adviser to the Portfolio, establishes specific target investment percentages for the asset classes and the various components of each asset category. BIA determines these target allocations based on a variety of models and factors, including its long-term outlook for the return and risk characteristics of the various asset classes and the relationship between those asset classes. BIA then selects the Underlying Portfolios in which the Portfolio invests based on, among other

factors, the Underlying Portfolios’ investment objectives, policies, investment processes and portfolio analytical and management personnel.

Under normal circumstances, the Portfolio invests substantially all of its assets in Underlying Portfolios that may hold large cap, small cap, mid cap or foreign equity securities in accordance with target allocations of 100% to equity securities.

The following chart describes the target allocations, as of April 28, 2025, to equity securities. You should note that these percentages do not directly correspond to investment in the Underlying Portfolios because each Underlying Portfolio may contain one or more asset classes (e.g., equity and fixed income) and each Underlying Portfolio may contain various subsets of an asset class (e.g., small cap, mid cap and foreign securities). Although the Portfolio’s investments in the Underlying Portfolios will be made in an attempt to achieve the target allocations, the actual allocations may vary from the Portfolio’s target allocations in the chart below. Deviations from the asset class target allocations will affect the asset class subset target allocations. In addition, the Portfolio’s actual allocations could vary substantially from the target allocations due to market valuation changes.

Asset Class	Target Allocation*
Equity	100%
U.S. Large Cap		43.5%
U.S. Mid Cap		12.5%
U.S. Small Cap		9%
Foreign Equity		35%

Individual figures may not add up to the totals shown due to rounding.

The “Foreign Equity” allocation shown above may be invested in foreign equity securities of any capitalization or country but primarily will be invested in larger capitalization companies of developed countries.

The Portfolio seeks to achieve capital growth through its investments in Underlying Portfolios that invest in equity securities. These investments include Underlying Portfolios that invest in stocks of large established U.S. companies, as well as, to a lesser extent, in stocks of foreign companies, including companies in emerging markets, and small U.S. companies with above-average growth potential.

Periodically, BIA will evaluate the Portfolio’s allocation between equity and fixed income, inclusive of the exposure to various investment styles and asset sectors, relative to the Portfolio’s risk profile. It is anticipated that any changes to the targets for the broad asset classes will be, in any given year, within a range of plus or minus 10% from the current allocations. Concurrently, BIA will consider whether to make changes to the Portfolio’s investments in any of the Underlying Portfolios.

For additional information about the Portfolio’s investment strategies, the names of the Underlying Portfolios in which the Portfolio may invest and where to find more detailed information about the Portfolio’s investments in the Underlying Portfolios, please see “Additional Information about this Portfolio’s Investment Strategies” in the Prospectus.

Principal Risks

As with all mutual funds, there is no guarantee that the Portfolio will achieve its investment objective. You could lose money by investing in the Portfolio. An investment in the Portfolio through a Contract is not a deposit or obligation of, or guaranteed by, any bank, and is not federally insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. Government.

There are direct and indirect risks of investing in the Portfolio. The value of your investment in the Portfolio may be affected by one or more of the following risks, which are described in more detail in “Principal Risks of Investing in the Portfolio” in the Prospectus. The significance of any specific risk to an investment in the Portfolio will vary over time, depending on the composition of the Portfolio, market conditions, and other factors. You should read all of the risk information presented below carefully, because any one or more of these risks could cause the Portfolio’s return, the price of the Portfolio’s shares or the Portfolio’s yield to fluctuate.

Direct risks of investing in the Portfolio include:

Underlying Portfolio Risk. The investment performance of a Portfolio that invests all or substantially all of its assets in Underlying Portfolios may be adversely affected if the Underlying Portfolios are unable to meet their investment objectives or the Portfolio allocates a significant portion of its assets to an Underlying Portfolio that performs poorly, including relative to other Underlying Portfolios. Any Underlying Portfolio may have multiple asset class exposures and such exposures may change over time. In addition, the Portfolio bears its pro-rata portion of the operating expenses of the Underlying Portfolios in which it invests.

Asset Allocation Risk. The Portfolio’s ability to achieve its investment objective depends upon BIA’s analysis of various factors and the mix of asset classes that results from such analysis, which may prove incorrect. The particular asset allocation selected for the Portfolio may not perform as well as other asset allocations that could have been selected for the Portfolio. The Portfolio may experience losses or poor relative performance if BIA allocates a significant portion of the Portfolio’s assets to an asset class that does not perform as BIA anticipated, including relative to other asset classes. The Portfolio may underperform funds that allocate their assets differently than the Portfolio.

Model and Data Risk. When the quantitative models (“Models”) and information and data (“Data”) used in managing the Portfolio contain an error, are input or designed incorrectly, or prove to be incorrect or incomplete, any investment decisions made in reliance on the Models and Data may not produce the desired results and the Portfolio may realize losses. Models may cause the Portfolio to underperform other investment strategies and may not perform as intended in volatile markets. In addition, any hedging based on faulty Models and Data may prove to be unsuccessful. Furthermore, the success of Models that are predictive in nature is dependent largely on the accuracy and reliability of the supplied historical data. All Models are susceptible to input errors which may cause the resulting information to be incorrect.

Indirect risks of investing in the Portfolio (direct risks of investing in the Underlying Portfolios) include:

Market Risk. An Underlying Portfolio’s share price can fall because of, among other things, a decline in the market as a whole, deterioration in the prospects for a particular industry or company, changes in general economic conditions, such as prevailing interest rates or investor sentiment, or other factors including terrorism, war, natural disasters and the spread of infectious illness including epidemics or pandemics. In addition, unexpected political, regulatory, trade and diplomatic events within the United States and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. Significant disruptions to the financial markets could adversely affect the liquidity and volatility of securities held by an Underlying Portfolio.

Foreign Investment Risk. Investments in foreign securities, whether direct or indirect, tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social, economic and other developments abroad, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. To the extent foreign securities are denominated in foreign currencies, their values may be adversely affected by changes in currency exchange rates. To the extent an Underlying Portfolio invests in foreign sovereign debt securities, it is subject to additional risks.

Emerging Markets Risk. In addition to all of the risks of investing in foreign developed markets, emerging market securities involve risks attendant to less mature and stable governments and economies, lower trading volume, trading suspension, security price volatility, proceeds repatriation restrictions, withholding and other taxes, some of which may be confiscatory, inflation, deflation, currency devaluation and adverse government regulations of industries or markets. As a result of these risks, the prices of emerging market securities tend to be more volatile than the securities of issuers located in developed markets.

Market Capitalization Risk. Investing primarily in issuers in one market capitalization category (large, medium or small) carries the risk that due to current market conditions that category will be out of favor with investors. Larger, more established companies may be unable to respond quickly to new competitive challenges or attain the high growth rate of successful smaller companies. Stocks of medium and small capitalization companies may be more volatile than those of larger companies due to, among other things, narrower product lines, more limited financial resources and fewer experienced managers. In addition, there is typically less publicly available information about small capitalization companies, and their stocks may have a more limited trading market than stocks of larger companies.

Investment Style Risk. Different investment styles such as growth or value tend to shift in and out of favor, depending on market and economic conditions as well as investor sentiment. An Underlying Portfolio may outperform or underperform other funds that employ a different investment style.

Real Estate Investment Risk. Investments in real estate investment trusts and other real estate related securities may be adversely impacted by the performance of the real estate market generally or that of a particular sub-sector or geographic region.

Derivatives Risk. An Underlying Portfolio may invest in derivatives to obtain investment exposure, enhance return or “hedge” or protect its assets from an unfavorable shift in the value or rate of a reference instrument or asset. Derivatives can be highly volatile and can significantly increase an Underlying Portfolio’s exposure to market risk, credit and counterparty risk (the risk that a counterparty will default or become less creditworthy) and other risks. Derivatives may be illiquid and difficult to value and can involve risks in addition to, and potentially greater than, the risks of the underlying reference instrument. Because of their complex nature, some derivatives may not perform as intended. As a result, an Underlying Portfolio may not realize the anticipated benefits from a derivative it holds or it may realize losses. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. Derivative transactions may create investment leverage, which increases an Underlying Portfolio’s volatility and may require the Underlying Portfolio to liquidate portfolio securities when it is not advantageous to do so. Government regulation of derivative instruments may limit or prevent an Underlying Portfolio from using such instruments as part of its investment strategies, which could adversely affect the Underlying Portfolio.

Portfolio Turnover Risk. The investment techniques and strategies utilized by the Underlying Portfolios might result in a high degree of portfolio turnover. High portfolio turnover rates will increase the Underlying Portfolios' transaction costs, which can adversely affect the returns on the Portfolio’s investments in those Underlying Portfolios.

The Portfolio and its related companies, including BIA, may make payments to the sponsoring insurance companies (or their affiliates) for distribution and/or other services, and the insurance companies may benefit more from offering the Portfolio as an investment option in the Contracts than offering other portfolios. The benefits to the insurance companies of offering the Portfolio over other portfolios and these payments may be factors that the insurance companies consider in including the Portfolio as an underlying investment option in the Contracts and may create a conflict of interest. The prospectus for your Contract contains additional information about these payments.
