Fees and Expenses of the Fund

These tables describe the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees (including on Class R6 and Advisor Class shares), such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales charge discounts in Class A if you and your family invest, or agree to invest in the future, at least $25,000 in Franklin Templeton funds and certain other funds distributed through Franklin Distributors, LLC, the Fund’s distributor. More information about these and other discounts is available from your financial professional and under “Your Account” on page 30 in the Fund’s Prospectus and under “Buying and Selling Shares” on page 44 of the Fund’s Statement of Additional Information. In addition, more information about sales charge discounts and waivers for purchases of shares through specific financial intermediaries is set forth in Appendix A – “Intermediary Sales Charge Discounts and Waivers” to the Fund’s prospectus.

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

FRANKLIN REAL ESTATE SECURITIES FUND
SUMMARY PROSPECTUS

^1. The investment manager has agreed to reduce its fees to reflect reduced services resulting from the Fund’s investments in Franklin Templeton affiliated funds. In addition, the transfer agency fees on Class R6 shares of the Fund have been capped so that transfer agency fees for that class do not exceed 0.03%. These arrangements are expected to continue until August 31, 2025. During the terms, the fee waiver and expense reimbursement agreements may not be terminated or amended without approval of the board of trustees except to add series or classes, to reflect the extension of termination dates or to lower the waiver and expense limitation (which would result in lower fees for shareholders).

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 and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects adjustments made to the Fund's operating expenses due to the fee waivers and/or expense reimbursements by management for the 1 Year numbers only. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 most recent fiscal year, the Fund's portfolio turnover rate was 17.38% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets in equity securities of companies operating in the real estate industry predominantly in the United States, including: companies qualifying under federal tax law as real estate investment trusts (REITs); and companies that derive at least half of their assets or revenues from the ownership, construction, management, operation, development or sale of commercial or residential real estate (such as real estate operating or service companies, homebuilders, lodging providers, and developers).

FRANKLIN REAL ESTATE SECURITIES FUND
SUMMARY PROSPECTUS

A REIT is a type of real estate company that is dedicated to owning and usually operating income-producing real estate such as apartments, hotels, industrial properties, office building or shopping centers. REITs typically concentrate on a specific geographic region or property type. The Fund's investments in REITs also include non-traditional REITs such as those that focus on storage and self-storage facilities, cell tower owners and data center owners. While the Fund is not limited to investing in REITs and REIT-like entities, it is expected that the Fund currently will focus on these types of entities. The Fund may also invest up to 20% of its net assets in equity securities of issuers engaged in businesses whose products and services are closely related to the real estate industry. These include companies that provide brokerage, leasing, advisory and management services to commercial and residential customers, companies that design and operate software platforms used by landlords and real estate service providers, and companies whose principal business is unrelated to the real estate industry but which have significant real estate holdings (at least 50% of their assets).

The Fund is a "non-diversified" fund, which means it generally invests a greater portion of its assets in the securities of one or more issuers and may invest overall in a smaller number of issuers than a diversified fund.

The Fund concentrates in securities of companies in the real estate industry, primarily REITs. The Fund currently expects to be invested predominantly in equity securities. The Fund may invest a small portion of its assets in securities of issuers in any foreign country, developed or developing, and in American, European and Global Depositary Receipts. In addition, certain U.S. REITs may hold significant positions in securities of foreign issuers.

When selecting investments for the Fund’s portfolio, the investment manager uses a “bottom-up" security selection process that incorporates macro-level views in the evaluation process. The investment manager’s portfolio construction process combines: bottom-up analysis of individual stock and real estate market fundamentals; and top-down macro overlays to provide regional, property type, and company size perspectives in identifying local cyclical and thematic trends that highlight investment opportunities.

Principal Risks

You could lose money by investing in the Fund. Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.

Real Estate Securities: By concentrating in the real estate industry, the Fund carries much greater risk of adverse developments in the real estate industry than

FRANKLIN REAL ESTATE SECURITIES FUND
SUMMARY PROSPECTUS

a fund that invests in a wide variety of industries. Because the Fund concentrates in the real estate industry, there is also the risk that the Fund will perform poorly during a slump in demand for real estate securities. To the extent that the Fund focuses on a particular geographical region of a country, the Fund may be subject to greater risks of adverse developments in that area than a fund that does not focus its investments in a particular region. Real estate values rise and fall in response to a variety of factors, including: local, regional, national and global economic conditions; interest rates; tax and insurance considerations; changes in zoning and other property-related laws; environmental regulations or hazards; overbuilding; increases in property taxes and operating expenses; or value decline in a neighborhood. When economic growth is slow, demand for property decreases and prices may decline.

REITs: A REIT’s performance depends on the types, values and locations of the properties and companies it owns and how well those properties and companies are managed. A decline in rental income may occur because of extended vacancies, increased competition from other properties, tenants’ failure to pay rent or poor management. Because a REIT may be invested in a limited number of projects or in a particular market segment, it may be more susceptible to adverse developments affecting a single project or market segment than more broadly diversified investments. Loss of status as a qualified REIT under the U.S. federal tax laws could adversely affect the value of a particular REIT or the market for REITs as a whole. These risks may also apply to securities of REIT-like entities domiciled outside the U.S.

Market: The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

Stock prices tend to go up and down more dramatically than those of debt securities. A slower-growth or recessionary economic environment could have an adverse effect on the prices of the various stocks held by the Fund.

Foreign Securities (non-U.S.): Investing in foreign securities typically involves more risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations. The risks of investing in foreign securities are typically greater in less developed or emerging market countries.

FRANKLIN REAL ESTATE SECURITIES FUND
SUMMARY PROSPECTUS

Trade disputes and the imposition of tariffs on goods and services can affect the economies of countries in which the Fund invests, particularly those countries with large export sectors, as well as the global economy. Trade disputes can result in increased costs of production and reduced profitability for non-export-dependent companies that rely on imports to the extent a country engages in retaliatory tariffs. Trade disputes may also lead to increased currency exchange rate volatility.

Non-Diversification: Because the Fund is non-diversified, it may be more sensitive to economic, business, political or other changes affecting individual issuers or investments than a diversified fund, which may negatively impact the Fund's performance and result in greater fluctuation in the value of the Fund’s shares.

Management: The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.

Cybersecurity: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents occurring from time to time.

SUMMARY PROSPECTUS

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund's performance from year to year for Class A shares. The table shows how the Fund's average annual returns for 1 year, 5 years, 10 years or since inception, as applicable, compared with those of a broad measure of market performance and an additional index with characteristics relevant to the Fund. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. You can obtain updated performance information at www.franklintempleton.com or by calling (800) DIAL BEN/342-5236.

Sales charges are not reflected in the bar chart, and if those charges were included, returns would be less than those shown.

Class A Annual Total Returns

FRANKLIN REAL ESTATE SECURITIES FUND
SUMMARY PROSPECTUS

Average Annual Total Returns

(figures reflect sales charges)

For periods ended December 31, 2023

¹ The inception date of the MSCI US IMI Real Estate 25/50 Index was September 1, 2016; however, the performance prior to its inception has been calculated by MSCI for purposes of the table above.

The figures in the average annual total returns table above reflect the Class A shares maximum front-end sales charge of 5.50%. Prior to September 10, 2018, Class A shares were subject to a maximum front-end sales charge of 5.75%. If the prior maximum front-end sales charge of 5.75% was reflected, performance for Class A shares in the average annual total returns table would be lower.

The after-tax returns presented in the table are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A and after-tax returns for other classes will vary.

Taxes

The Fund’s distributions are generally taxable to you as ordinary income, capital gains, or some combination of both, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account, in which case your distributions would generally be taxed when withdrawn from the tax-advantaged account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your financial advisor or visit your financial intermediary's website for more information.
