companies affiliated with Brighthouse Investment Advisers, LLC, and is not intended for use by other investors.

Investment Objective

Long-term 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	Class E
Management Fee	0.75%	0.75%	0.75%
Distribution and/or Service (12b-1) Fees	None	0.25%	0.15%
Other Expenses	0.03%	0.03%	0.03%
Total Annual Portfolio Operating Expenses	0.78%	1.03%	0.93%
Fee Waiver1	(0.08% )	(0.08% )	(0.08% )
Net Operating Expenses	0.70%	0.95%	0.85%

Brighthouse Investment Advisers, LLC has contractually agreed, for the period May 1, 2024 through April 30, 2025, to reduce the Management Fee for each class of the Portfolio. This arrangement may be modified or discontinued prior to April 30, 2025, only with the approval of the Board of Trustees of the Portfolio.

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, that the Portfolio’s operating expenses remain the same, and that all fee waivers for the Portfolio will expire after one year. 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	$72	$241	$425	$959
Class B	$97	$320	$561	$1,252
Class E	$87	$288	$507	$1,136

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 Example, affect the Portfolio’s performance.
During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 22% of the average value of its portfolio.

Principal Investment Strategies

T. Rowe Price Associates, Inc., subadviser to the Portfolio, and T. Rowe Price Investment Management, Inc., sub-subadviser to the Portfolio (together with T. Rowe Price Associates, Inc., “T. Rowe Price” or “Subadviser”), invests, under normal circumstances, at least 80% of the Portfolio’s net assets in a diversified portfolio of common stocks, including common stocks purchased through initial public offerings (“IPOs”), of mid cap companies whose earnings T. Rowe Price expects to grow at a faster rate than the average company. T. Rowe Price defines mid cap companies as those whose market capitalization falls within the range of either the S&P MidCap 400® Index or the Russell Midcap Growth

Index. As of December 31, 2023, the market capitalizations of companies in the S&P MidCap 400 Index ranged from $1.7 billion to $17.9 billion. As of December 31, 2023, the market capitalizations of companies in the Russell Midcap Growth Index ranged from $666 million to $71.1 billion. The market capitalization of the companies and the S&P and Russell indices change over time. The Portfolio will not automatically sell or cease to purchase stock of a company it already owns because the company’s market capitalization grows or falls outside this range. The Portfolio may, from time to time, emphasize one or more sectors.

As “growth” investors, T. Rowe Price believes that when a company’s earnings grow faster than both inflation and the overall economy, the market will eventually reward it with a higher stock price. In selecting investments, T. Rowe Price generally favors companies that:

■

have proven products or services;

■

have a record of above-average earnings growth;

■

have demonstrated potential to sustain earnings growth;

■

have a connection to industries experiencing increasing demand; or

■

have stock prices that appear to undervalue their growth prospects.

In pursuing the Portfolio’s investment objective, T. Rowe Price has the discretion to purchase some securities that do not meet its normal investment criteria, as described above, when it perceives an opportunity for substantial appreciation. These situations might arise when T. Rowe Price believes a security could increase in value for a variety of reasons, including a change in management, an extraordinary corporate event, a new product introduction or innovation, or a favorable competitive development.

While most assets will be invested in U.S. common stocks, other securities may also be purchased, including foreign stocks, in keeping with the Portfolio’s objectives. The Portfolio may invest up to 25% of its assets in foreign securities. The Portfolio may sell securities for a variety of reasons, such as to secure gains, limit losses or redeploy assets into more promising opportunities.

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.

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.

Market Risk. The 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 such as the COVID-19 pandemic. Significant disruptions to the financial markets could adversely affect the liquidity and volatility of securities held by the 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. All of the risks of investing in foreign securities are typically increased by investing in emerging market countries.

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. The Portfolio may outperform or underperform other funds that employ a different investment style.

Focused Investment Risk. Substantial investments in a relatively small number of securities or issuers, or a particular market, industry, group of industries, country, region, group of countries, asset class or sector make the Portfolio’s performance more susceptible to any single economic, market, political or

T. Rowe Price Mid Cap Growth Portfolio

regulatory occurrence affecting those particular securities or issuers or that particular market, industry, group of industries, country, region, group of countries, asset class or sector than a portfolio that invests more broadly.

Past Performance

The information below provides some indication of the risks of investing in the Portfolio by showing changes in the Portfolio’s performance from year to year and how the Portfolio’s average annual returns over time compare with those of a broad-based securities market index. Note that the results in the bar chart and table do not include the effect of Contract charges. If these Contract charges had been included, performance would have been lower. As with all mutual funds, past returns are not a prediction of future returns.

Payments to Broker-Dealers and Other Financial
Intermediaries

The Portfolio is not sold directly to the general public but instead is offered as an underlying investment option for Contracts issued by insurance companies, including insurance companies that are affiliated with the Portfolio and BIA. 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.
