Investment Goal

This Fund seeks long-term growth of capital.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Examples below. The table and Examples below also do not reflect expenses and charges that are imposed under your variable annuity contract or variable life insurance policy. For information on these expenses and charges, please refer to the applicable contract or policy prospectus. If these fees and expenses were included, the fees and expenses shown would be higher.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

​

1

The investment adviser has agreed to waive 0.015% of its management fee through April 30, 2027. Thereafter, the fee waiver agreement renews annually unless terminated by the investment adviser upon at least 30 days written notice prior to the end of the contract term or upon termination of the investment advisory agreement or by the Trust upon 90 days’ written notice to the investment adviser.​

​

Examples

The Examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other Funds of the Trust or other mutual funds. The Examples assume that you invest $10,000 for the time periods indicated, that your investment has a 5% return each year and that the Fund’s annual operating expenses remain as stated in the previous table for

the time periods shown except for the fee waiver, which is only reflected for the contractual period. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

These Examples do not reflect fees and expenses of any variable annuity contract or variable life insurance policy. If these were included, the expenses (in dollars) shown would be higher. Keep in mind that this is only an estimate; actual expenses and performance may vary.

Your expenses (in dollars) if you buy, sell/redeem or hold all of your shares at the end of each period

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its holdings). During the fiscal year ended December 31, 2025, the portfolio turnover rate was 67% of the average value of the Fund. A higher portfolio turnover rate reflects a greater number of securities being bought or sold, which may indicate higher transaction costs. These costs, which are not reflected in Annual Fund Operating Expenses or in the Examples, affect the Fund’s performance.

Principal Investment Strategies

Under normal circumstances, this Fund invests at least 80% of its assets in securities of companies with small market capitalizations. The sub-adviser generally considers a company to be a small-capitalization company if the company has a market capitalization within the range of companies included in the MSCI Europe, Australasia and Far East (“EAFE”) Small Cap Index or the MSCI All Country World Index (“ACWI”) ex USA Small Cap Index, indices which measure the performance of the small-capitalization segment of the international equity universe. The size of the companies in each index changes with market conditions and the composition of the index. As of

December 31, 2025, the market capitalization range of the MSCI EAFE Small Cap Index was approximately $142.5 million to $15.2 billion, and the market capitalization range of the MSCI ACWI ex USA Small Cap Index was approximately $126.6 million to $15.2 billion. As of December 31, 2025, the weighted average market capitalization of the Fund was approximately $5.5 billion.

Normally, the Fund invests primarily in non-U.S. securities, including securities of issuers located in emerging markets, that may be U.S. dollar or foreign currency-denominated. The Fund normally invests primarily in common stocks. The sub-adviser normally allocates the Fund’s investments across different countries and regions, such as Japan. The sub-adviser anticipates that the Fund will have a focus in and risk exposure to the largest country constituents of the MSCI ACWI ex USA Small Cap Index. These constituents may change over time.

The sub-adviser considers the broad market sectors of investments in its management of the Fund. As of December 31, 2025, a significant portion of the Fund was represented by securities of companies in the Industrial sector.

In buying and selling securities for the Fund, the sub-adviser uses fundamental analysis of factors such as each issuer’s financial condition and industry position, as well as market and economic conditions.

The Fund may lend its portfolio holdings to certain financial institutions.

Principal Risks

As with any mutual fund, the value of the Fund’s investments, and therefore the value of your shares, may go up or down and you could lose money. There is no guarantee that the Fund will achieve its investment goal. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Italicized terms refer to separate Principal Risks that are each defined in the Principal Risks section below.

While the Fund may be subject to various risk exposures at any given time depending on market conditions and other factors impacting holdings and investment strategies, the Fund under normal circumstances is subject to the following principal risks:

•

Equity Securities Risk: Equity securities tend to go up and down in value, sometimes rapidly and unpredictably.

​

•

Foreign (Non-U.S.) Markets Risk: Investing in foreign issuers (companies or other entities) can involve more risks than investing in United States (“U.S.”) issuers, such as risks relating to market, economic, political, regulatory and geopolitical conditions relevant to that market. These factors can make investments in foreign issuers more volatile and less liquid than U.S. investments. Less stringent regulatory, accounting, and disclosure requirements and general supervision for issuers and markets are more common in certain foreign countries. Enforcing legal rights can be difficult, costly, and slow in certain foreign countries, and can be particularly difficult against foreign governments. In addition, foreign markets can react differently to these conditions than the U.S. market. 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, or foreign exchange rates with, another market, country or region.

•

Small-Capitalization Companies Risk: Small-capitalization companies may be more susceptible to liquidity risk and price volatility and be more vulnerable to economic, market and industry changes than larger, more established companies.

​

•

Emerging Markets Risk: Investments in or exposure to investments in emerging market countries may be riskier than investments in or exposure to investments in U.S. and other developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, lower credit quality, a higher degree of political and economic instability, the impact of economic sanctions, less governmental regulation and supervision of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.

​

•

Currency Risk: A decline in the value of a foreign (non-U.S.) currency relative to the U.S. dollar reduces the value in U.S. dollars of the Fund’s investments denominated in or with exposure to that foreign currency.

​

•

Value Companies Risk: Value companies are those that a portfolio manager believes are undervalued and trading for less than their intrinsic values. There is a risk that the determination that a stock is undervalued is not correct or is not recognized in the market.

​

•

Active Management Risk: A portfolio manager’s judgments about the potential value or price appreciation of an investment may prove to be incorrect or fail to have the intended results, which could negatively impact the Fund’s performance.

​

•

Growth Companies Risk: Growth companies are those that a portfolio manager believes have the potential for above average or rapid growth but may be subject to greater price volatility than investments in “undervalued” companies.

​

•

Geographic Focus Risk: If the Fund invests a significant portion of its assets in a single country, limited number of countries, or particular geographic region, then the risk increases that economic, political, social, or other conditions in those countries or that region will have a significant impact on the Fund’s performance. As a result, the Fund’s performance may be more volatile than the performance of more geographically diversified funds.

​

•

Japan Risk: Because the Fund has principal exposure to investments (both directly and indirectly) relating to Japan, the Fund may be impacted by social, economic and political conditions impacting Japan, including governmental policies, currency fluctuations, international relationships, public health risks, natural disasters and other risks.

​

•

Liquidity Risk: Certain holdings may be difficult to purchase, sell and value, particularly during adverse market conditions, because there is a limited market for the investment or there are restrictions on resale. The Fund may not be able to sell a holding quickly at the price it has valued the holding, may be unable to take advantage of market opportunities or may be forced to sell other more desirable, more liquid

​

securities or sell less liquid or illiquid securities at a loss if needed to raise cash to conduct operations, including to meet redemption requests.

•

Industrial Sector Risk: Industrial companies are affected by supply and demand both for their specific product or service and for industrial sector products in general. Government regulation, world events, exchange rates and economic conditions will likewise affect the performance of these companies. For example, aerospace and defense companies can be significantly affected by government spending policies because they rely significantly on government demand for their products and services. Transportation securities, another component of the industrial sector, are cyclical and have occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs.

​

•

Underlying Fund Risk: Because the Fund is available for investment by one or more “fund of funds” of the Trust and thus may have a significant percentage of its outstanding shares held by such fund of funds, a change in asset allocation by the fund of funds could result in large redemptions out of the Fund, causing the sale of securities in a short timeframe and potential increases in expenses to the Fund and its remaining shareholders, both of which could negatively impact performance.

​

•

Securities Lending Risk: The Fund may engage in securities lending, which involves the risk that the Fund may suffer a loss if the borrower fails to return the loaned securities in a timely manner or at all. The Fund could also lose money due to the decline in the value of the collateral provided or a decline in the value of any investments made with cash collateral.

​

Performance

The bar chart and Average Annual Total Returns table below show performance information for the Fund and provide some indication of the risk of investing in the Fund by showing changes in the performance of the Fund from year to year and showing how the Fund’s average annual total returns compare to the returns of:

•

a broad-based international equity market index that represents the overall international equity market (the “Regulatory Index”) which the Fund has included to comply with regulatory requirements and thus may not necessarily represent the Fund’s principal investment strategies; and

​

•

a small-capitalization international equity market index that the Investment Adviser considers to be representative of the small-capitalization international equity markets and the Fund’s principal investment strategies. The Investment Adviser considers this index to be the appropriate benchmark index for the Fund for performance comparison.

​

The bar chart shows the performance of the Fund’s Class I shares. Returns do not reflect fees and expenses of any variable annuity contract or variable life insurance policy; if these fees and expenses were included, the returns shown would be lower. Past performance is not necessarily an indication of how the Fund will perform in the future. Performance reflects fee waivers or expense limitations, if any, that were in effect during the periods presented.

FIAM LLC began managing the Fund on November 1, 2021, and some investment policies changed at that time. Another firm managed the Fund before that date.

Management

Investment Adviser — Pacific Life Fund Advisors LLC

Sub-Adviser — FIAM LLC. The person primarily responsible for day-to-day management of the Fund is:

Purchase and Sale of Fund Shares

The Fund is offered at net asset value (“NAV”) and is available as an underlying investment option for variable life insurance policies and variable annuity contracts (“variable products”) issued by Pacific Life and PL&A. You do not buy, sell or exchange shares of the Fund — you choose investment options through your variable product. The life insurance companies then invest in the Fund if you choose it as an investment option and redeem shares of the Fund if you choose to decrease that investment option. Any minimum initial or subsequent investment requirements and procedures for purchase or redemption of shares of the Fund that apply to your variable product are described in the prospectus for the variable product.

Tax Information

Because the only shareholders of the Fund are the insurance companies offering the variable products and as applicable certain funds of funds of the Trust, no discussion is included here about the federal income tax consequences at the shareholder level. The federal income tax consequences for purchasers of a variable product are described in the prospectus for the variable product.
