Portfolio Turnover

The Fund 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 and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund's performance. During the Fund's most recent fiscal year, the Fund's portfolio turnover rate was 97% of the average value of its portfolio.

What are the Fund's main investment strategies?

Under normal circumstances, the Fund invests at least 80% of its Assets in equity securities of small cap U.S. companies. Small cap companies are companies with market capitalizations similar to those within the universe of the Russell 2000® Index at the time of purchase. As of the reconstitution of the Russell 2000 Index on September 30, 2026, the market capitalizations of the companies in the index ranged from $5.62 million to $85.78 billion. "Assets" means net assets, plus the amount of borrowings for investment purposes. Sector by sector, the Fund's weightings are similar to those of the Russell 2000® Index. The Fund can moderately underweight or overweight sectors when it believes it will benefit performance. The Fund pursues returns that exceed those of the Russell 2000® Index while seeking to limit its volatility relative to this index. In implementing its main strategies, the Fund's investments are primarily in common stocks and real estate investment trusts (REITs).

Derivatives, which are instruments that have a value based on another instrument, exchange rate or index, may be used as substitutes for securities in which the Fund can invest. The Fund may use futures contracts to gain or reduce exposure to its index, maintain liquidity and minimize transaction costs. In managing cash flows, the Fund buys futures contracts to invest incoming cash in the market or sells futures contracts in response to cash outflows, thereby gaining market exposure to the index while maintaining a cash balance for liquidity.

An issuer of a security will be deemed to be located in the United States if: (i) the principal trading market for the security is in the United States, (ii) the issuer is organized under the laws of the United States, or (iii) the issuer derives at least 50% of its revenues or profits from the United States or has at least 50% of its total assets situated in the United States.

Investment Process: In managing the Fund, the adviser employs a process that ranks stocks based on its proprietary stock ranking system. The rankings are then reviewed and adjusted utilizing fundamental research conducted by the investment team to enhance accuracy and consistency. The adjusted rankings are used to place stocks into portfolios.

As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser's assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund's investments in issuers and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive, and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors.

In general, stocks are purchased when they are among the top ranked within their sector. Stocks become candidates for sale when their ranking falls, when they appear unattractive or when the company is no longer a small cap company. The Fund may continue to hold the securities if it believes further substantial growth is possible. Risk factor exposures are managed through portfolio construction. Portfolio constraints control for sector weights, position sizes and/or style characteristics of the Fund.

The Fund's Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser's expectations regarding particular instruments or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

The Fund is subject to the main risks noted below, any of which may adversely affect the Fund's net asset value (NAV), market price, performance and ability to meet its investment objective.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company's financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund's portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund's securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund's portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due

to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, trade wars, retaliatory trade measures, sanctions and other trade barriers, supply chain disruptions, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund's investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or the threat or potential of one or more such factors and occurrences.

Smaller Company Risk. Investments in smaller companies may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than investments in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, the share price changes may be more sudden or erratic than the prices of securities of larger companies, especially over the short term.

Real Estate Securities Risk. The Fund's investments in real estate securities, including REITs, are subject to the same risks as direct investments in real estate and mortgages, and their value will depend on the value of the underlying real estate interests. These risks include default, prepayments, changes in value resulting from changes in interest rates and demand for real and rental property, and the management skill and credit-worthiness of REIT issuers. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

Derivatives Risk. Derivatives, including futures contracts, may be riskier than other types of investments and may increase the volatility of the Fund. Derivatives may be sensitive to changes in economic and market conditions and may create leverage, which could result in losses that significantly exceed the Fund's original investment. The Fund may be more volatile than if the Fund had not been leveraged because the leverage tends to exaggerate any effect on the value of the Fund's portfolio securities. Certain derivatives expose the Fund to counterparty risk, which is the risk that the derivative counterparty will not fulfill its contractual obligations (and includes credit risk associated with the counterparty). Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund to risks of mispricing or improper valuation. Derivatives also can expose the Fund to derivative liquidity risk, which includes risks involving the liquidity demands that derivatives can create to make payments of margin, collateral, or settlement payments to counterparties, legal risk, which includes the risk of loss resulting from insufficient or unenforceable contractual documentation, insufficient capacity or authority of the Fund's counterparty and operational risk, which includes documentation or settlement issues, system

failures, inadequate controls and human error. Certain of the Fund's transactions in foreign currency derivatives and other derivatives could also affect the amount, timing and character of distributions to shareholders which may result in the Fund realizing more ordinary income and short-term capital gain subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund's after-tax returns.

Industry and Sector Focus Risk. At times, the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, contagion risk within a particular industry or sector or to other industries or sectors, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of the Fund's shares may fluctuate in response to events affecting that industry or sector.

Healthcare Sector Risk. Companies in the healthcare sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services. Companies in the healthcare sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of these companies. Healthcare companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the healthcare sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market.

Financials Sector Risk. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change or due to increased competition. In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financials sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with

investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities or liquidating other investments to meet redemption requests. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

The Fund's Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund's Class L Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares the Fund's performance to the performance of the Russell 3000® Index and Russell 2000® Index. The Russell 3000® Index serves as the Fund's regulatory index and provides a broad measure of market performance. The Russell 2000® Index is the Fund's additional index and is more representative of the Fund's investment universe than the regulatory index. Past performance (before and after taxes) is not necessarily an indication of how any class of the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.
