Fees and Expenses of the Fund

The following 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.

ANNUAL FUND OPERATING EXPENSES (Expenses that you pay each year as a percentage of the value of your investment)
	Class R2	Class R3	Class R4	Class R5	Class R6
Management Fees	0.75%	0.75%	0.75%	0.75%	0.75%
Distribution (Rule 12b-1) Fees	0.50	0.25	NONE	NONE	NONE
Other Expenses	0.37	0.35	0.35	0.19	0.09
Service Fees	0.25	0.25	0.25	0.10	NONE
Remainder of Other Expenses	0.12	0.10	0.10	0.09	0.09
Total Annual Fund Operating Expenses	1.62	1.35	1.10	0.94	0.84
Fee Waivers and/or Expense Reimburse- ments 1	-0.07	-0.05	-0.05	-0.04	-0.04
Total Annual Fund Operating Expenses after Fee Waivers and/or Expense Reimbursements 1	1.55	1.30	1.05	0.90	0.80

The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding acquired fund fees and expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 1.55%, 1.30%, 1.05%, 0.90% and 0.80% of the average daily net assets of Class R2, Class R3, Class R4, Class R5 and Class R6 Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds.

These waivers are in effect through 10/31/26, at which time it will be determined whether such waivers will be renewed or revised. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the fee table through 10/31/26 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR COST WOULD BE:
	1 Year	3 Years	5 Years	10 Years
CLASS R2 SHARES ($)	158	504	875	1,916
CLASS R3 SHARES ($)	132	423	735	1,620
CLASS R4 SHARES ($)	107	345	601	1,336
CLASS R5 SHARES ($)	92	296	516	1,151
CLASS R6 SHARES ($)	82	264	462	1,033

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 35% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund seeks to achieve its objective by investing in common stocks of U.S. companies that the Fund’s sub-adviser, Fuller & Thaler Asset Management, Inc. (FullerThaler), believes have value characteristics. Such common stocks often include, but are not limited to, stocks of small capitalization companies,

similar to those that are included in the Russell 2000® Value Index. FullerThaler's strategy focuses on, but is not limited to, the Fund investing in small capitalization companies; additionally, the Fund may buy, continue to hold, as well as make additional investments in, a stock if it is above, or has appreciated beyond the market capitalization of the largest company included in the Russell 2000® Value Index. The Fund may also invest in real estate investment trusts (REITs).

A REIT is a pooled investment vehicle that generally invests in income-producing real estate or real estate-related loans or interests. REITs are classified as equity REITs, mortgage REITs or hybrid REITs. Equity REITs, which invest the majority of their assets directly in real property, derive their income primarily from rents.

In selecting stocks for the Fund, FullerThaler applies principles based on behavioral finance. FullerThaler believes that behavioral biases on the part of investors may cause the market to overreact to old, negative information and underreact to new, positive information concerning a company. In an effort to take advantage of such behavioral biases, FullerThaler generally utilizes a three-pronged approach that includes (i) positive signals such as significant share purchases by company insiders or stock repurchase activity by the company, (ii) evidence of overreaction due to behavioral factors that have resulted in an absolute or relative decline in valuation and (iii) analysis of the company fundamentals with regard to business model, valuation and credit risk.

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 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, sanctions and other trade barriers, 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.

Behavioral Strategy Risk. When taking investment positions, FullerThaler will apply principles based on behavioral finance. In order to take advantage of behavioral biases, FullerThaler generally focuses on certain markers of possible under and overreaction by investors. Securities identified using this type of strategy may perform differently from the market for various reasons, including the criteria used in the analysis, the weight placed on each criterion, and changes in the criterion’s historical trends. The criteria used in implementing this strategy and the weight placed on those criteria may not be predictive of a security’s value, and the effectiveness of the criteria can change over time. These changes may not be reflected in the current analytical approach used to implement the behavioral strategy. FullerThaler’s strategy based on behavioral finance may be less effective in certain market environments. For example, the Fund invests when FullerThaler believes other investors are over-reacting to significant negative news coverage about a security. As a result, the Fund may experience substantial under-performance during such periods of investor “overreaction,” including as compared to the market overall, the Fund's benchmark and/or to other funds that do not employ a behavioral finance strategy. There can be no guarantee that FullerThaler will be successful in applying behavioral finance principles in managing the Fund.

Smaller Company Risk. Investments in securities of smaller companies (mid cap and small cap companies) may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than securities of 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, changes in the price of securities issued by such companies may be more sudden or erratic than the prices of securities of larger companies, especially over the short term. These risks are higher for small cap companies.

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Larger Capitalization Company Risk. Although the Fund invests primarily in securities of small cap companies, it may invest in equity investments of larger capitalization companies and, to the extent it does, it may underperform other funds during periods when the Fund's larger capitalization securities are out of favor.

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, decreases in real estate values, overbuilding, increased competition and other risks related to local or general economic conditions, increases in operating costs and property taxes, changes in zoning laws, casualty or condemnation losses, possible environmental liabilities, regulatory limitations on rent, possible lack of availability of mortgage financing, market saturation, fluctuations in rental income and the value of underlying properties and extended vacancies of properties, and the management skill and creditworthiness 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.

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. In particular, small capitalization value funds and indices typically have a large weighting in both the financials sector as well as the banking industry. Due to the Fund’s emphasis on small capitalization value stocks, the Fund will typically have a large weighting in the financials sector as well as the banking industry. Developments affecting the financial sector or banking industry may have a significant impact on the value of the Fund’s shares. Those developments may include changes in economic or business conditions, financial markets, government policy and regulations, competition, and interest rates. The Fund may from time to time hold either a larger or smaller weight in the financials sector or banking industry group compared to its benchmark, the Russell 2000® Value Index.

Industrials Sector Risk. The industrials sector may be adversely affected by changes in the supply of and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities 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.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

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 R2 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 the Russell 2000® Value Index. The Russell 3000 Index serves as the Fund’s regulatory index and provides a broad measure of market performance. The Russell 2000 Value Index is the Fund’s additional index and is more representative of the Fund’s investment universe than the regulatory index. The performance of Class R3 Shares prior to its inception is based on the performance of the Class A Shares (which are not offered in this prospectus). The actual returns of Class R3 Shares would have been similar to those shown because Class R3 Shares have similar expenses to Class A Shares. The performance of Class R4 Shares is based on the performance of the Class I Shares (which are not offered in this prospectus). The actual returns of Class R4 Shares would have been similar to those shown because Class R4 Shares have similar expenses to Class I Shares. The performance of Class R5 Shares prior to its inception is based on the performance of the Class L Shares (which are not offered in this prospectus). The actual returns of Class R5 Shares would have been similar than those shown because Class R5 Shares have similar expenses than Class L Shares. 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.
