SUPPLEMENT DATED APRIL 1, 2024

TO THE STATEMENT OF ADDITIONAL INFORMATION (“SAI”) OF

CLEARBRIDGE SMALL CAP FUND AND CLEARBRIDGE VALUE FUND

DATED MARCH 1, 2024

The following information supplements the funds’ SAI:

At the special meeting of shareholders of the ClearBridge Small Cap Fund and ClearBridge Value Fund (each a “Fund” and collectively, the “Funds”) held on April 1, 2024, shareholders approved the proposals to approve: (1) a new management agreement with Franklin Templeton Fund Adviser, LLC (“FTFA”) whereby FTFA will provide overall management and administrative services to the Funds; (2) a new subadvisory agreement between FTFA and ClearBridge Investments, LLC (“ClearBridge”) whereby ClearBridge will provide day-to-day portfolio management services to the Funds as a subadviser to the Funds; (3) a new cash management subadvisory agreement between FTFA and Western Asset Management Company, LLC (“Western Asset”) whereby Western Asset will provide cash management services to the Funds with respect to those assets that are allocated to Western Asset; (4) changes to each Fund’s fundamental investment policies relating to borrowing money, underwriting, lending, issuing senior securities, real estate, commodities, and concentration; and (5) an authorization for the Funds to rely on a “Manager of Managers” exemptive order, which would allow the Funds’ manager to appoint affiliated and unaffiliated subadvisers to provide subadvisory services to the Funds, without a shareholder vote, but subject to the approval of the Funds’ Board of Trustees.

As a result, effective April 1, 2024, the following changes are made to the Funds’ SAI.

I. The following text supplements and supersedes any information to the contrary in the section of the Funds’ SAI titled “Investment Policies – Fundamental Investment Policies”:

Fundamental Investment Policies – Small Cap Fund and Value Fund

The Fund’s fundamental investment policies are as follows:

• Borrowing: The Fund may not borrow money except as permitted by (i) the 1940 Act, or interpretations or modifications by the SEC, SEC staff or other authority with appropriate jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority.

• Underwriting: The Fund may not engage in the business of underwriting the securities of other issuers except as permitted by (i) the 1940 Act, or interpretations or modifications by the SEC, SEC staff or other authority with appropriate jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority.

• Loans: The Fund may lend money or other assets to the extent permitted by (i) the 1940 Act, or interpretations or modifications by the SEC, SEC staff or other authority with appropriate jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority.

• Senior Securities: The Fund may not issue senior securities except as permitted by (i) the 1940 Act, or interpretations or modifications by the SEC, SEC staff or other authority with appropriate jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority.

• Real Estate: The Fund may not purchase or sell real estate except as permitted by (i) the 1940 Act, or interpretations or modifications by the SEC, SEC staff or other authority with appropriate jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority.

• Commodities: The Fund may purchase or sell commodities or contracts related to commodities to the extent permitted by (i) the 1940 Act, or interpretations or modifications by the SEC, SEC staff or other authority with appropriate jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC staff or other authority.

• Concentration: Except as permitted by exemptive or other relief or permission from the SEC, SEC staff or other authority with appropriate jurisdiction, the Fund may not make any investment if, as a result, the Fund’s investments will be concentrated in any one industry.

With respect to the fundamental policy relating to borrowing money set forth above, the 1940 Act permits a fund to borrow money in amounts of up to one-third of the fund’s total assets from banks for any purpose, and to borrow up to 5% of the fund’s total assets from banks or other lenders for temporary purposes. (A fund’s total assets include the amounts being borrowed.) To limit the risks attendant to borrowing, the 1940 Act requires a fund to maintain an “asset coverage” of at least 300% of the amount of its borrowings, provided that in the event that the fund’s asset coverage falls below 300%, the fund is required to reduce the amount of its borrowings so that it meets the 300% asset coverage threshold within three days (not including Sundays and holidays). Asset coverage means the ratio that the value of a fund’s total assets (including amounts borrowed), minus liabilities other than borrowings, bears to the aggregate amount of all borrowings. Certain trading practices and investments, such as reverse repurchase agreements, may be considered to be borrowing and thus subject to the 1940 Act restrictions. Borrowing money to increase portfolio holdings is known as “leveraging.” Borrowing, especially when used for leverage, may cause the value of the Fund’s shares to be more volatile than if the Fund did not borrow. This is because borrowing tends to magnify the effect of any increase or decrease in the value of the Fund’s portfolio holdings. Borrowed money thus creates an opportunity for greater gains, but also greater losses. To repay borrowings, the Fund may have to sell securities at a time and at a price that is unfavorable to the Fund. There also are costs associated with borrowing money, and these costs would offset and could eliminate the Fund’s net investment income in any given period. Currently, the Fund does not contemplate borrowing money for leverage, but if the Fund does so, it will not likely do so to a substantial degree. The policy above will be interpreted to permit the Fund to engage in trading practices and investments that may be considered to be borrowing to the extent permitted by the 1940 Act. Short-term credits necessary for the settlement of securities transactions and arrangements with respect to securities lending will not be considered to be borrowings under the policy. Practices and investments that may involve leverage but are not considered to be borrowings are not subject to the policy.

With respect to the fundamental policy relating to underwriting set forth above, the 1940 Act does not prohibit a fund from engaging in the underwriting business or from underwriting the securities of other issuers; in fact, the 1940 Act permits a fund to have underwriting commitments of up to 25% of its assets under certain circumstances. Those circumstances currently are that the amount of the fund’s underwriting commitments, when added to the value of the fund’s investments in issuers where the fund owns more than 10% of the outstanding voting securities of those issuers, cannot exceed the 25% cap. A fund engaging in transactions involving the acquisition or disposition of portfolio securities may be considered to be an underwriter under the 1933 Act. Under the 1933 Act, an underwriter may be liable for material omissions or misstatements in an issuer’s registration statement or prospectus. Securities purchased from an issuer and not registered for sale under the 1933 Act are considered restricted securities. There may be a limited market for these securities. If these securities are registered under the 1933 Act, they may then be eligible for sale but participating in the sale may subject the seller to underwriter liability. These risks could apply to a fund investing in restricted securities. Although it is not believed that the application of the 1933 Act provisions described above would cause the Fund to be engaged in the business of underwriting, the policy above will be interpreted not to prevent the Fund from engaging in transactions involving the acquisition or disposition of portfolio securities, regardless of whether the Fund may be considered to be an underwriter under the 1933 Act.

2

With respect to the fundamental policy relating to lending set forth above, the 1940 Act does not prohibit a fund from making loans; however, SEC staff interpretations currently prohibit funds from lending more than one-third of their total assets, except through the purchase of debt obligations or the use of repurchase agreements. (A repurchase agreement is an agreement to purchase a security, coupled with an agreement to sell that security back to the original seller on an agreed-upon date at a price that reflects current interest rates. The SEC frequently treats repurchase agreements as loans.) While lending securities may be a source of income to the Fund, as with other extensions of credit, there are risks of delay in recovery or even loss of rights in the underlying securities should the borrower fail financially. However, loans would be made only when the Fund’s Manager or a Subadviser believes the income justifies the attendant risks. The Fund also will be permitted by this policy to make loans of money, including to other funds. The Fund would have to obtain exemptive relief from the SEC to make loans to other funds. The policy above will be interpreted not to prevent the Fund from purchasing or investing in debt obligations and loans. In addition, collateral arrangements with respect to options, forward currency and futures transactions and other derivative instruments, as well as delays in the settlement of securities transactions, will not be considered loans.

With respect to the fundamental policy relating to issuing senior securities set forth above, “senior securities” are defined as fund obligations that have a priority over the fund’s shares with respect to the payment of dividends or the distribution of fund assets. The 1940 Act prohibits a fund from issuing senior securities except that the fund may borrow money in amounts of up to one-third of the fund’s total assets from banks for any purpose. A fund also may borrow up to 5% of the fund’s total assets from banks or other lenders for temporary purposes, and these borrowings are not considered senior securities. The issuance of senior securities by a fund can increase the speculative character of the fund’s outstanding shares through leveraging. Leveraging of the Fund’s portfolio through the issuance of senior securities magnifies the potential for gain or loss on monies, because even though the Fund’s net assets remain the same, the total risk to investors is increased to the extent of the Fund’s gross assets. The policy above will be interpreted not to prevent collateral arrangements with respect to swaps, options, forward or futures contracts or other derivatives, or the posting of initial or variation margin.

With respect to the fundamental policy relating to real estate set forth above, the 1940 Act does not prohibit a fund from owning real estate; however, a fund is limited in the amount of illiquid assets it may purchase. Investing in real estate may involve risks, including that real estate is generally considered illiquid and may be difficult to value and sell. Owners of real estate may be subject to various liabilities, including environmental liabilities. To the extent that investments in real estate are considered illiquid, an SEC rule limits a fund’s purchases of illiquid securities to 15% of net assets. The policy above will be interpreted not to prevent the Fund from investing in real estate-related companies, companies whose businesses consist in whole or in part of investing in real estate, instruments (like mortgages) that are secured by real estate or interests therein, or real estate investment trust securities.

With respect to the fundamental policy relating to commodities set forth above, the 1940 Act does not prohibit a fund from owning commodities, whether physical commodities and contracts related to physical commodities (such as oil or grains and related futures contracts), or financial commodities and contracts related to financial commodities (such as currencies and, possibly, currency futures). However, a fund is limited in the amount of illiquid assets it may purchase. To the extent that investments in commodities are considered illiquid, an SEC rule limits a fund’s purchases of illiquid securities to 15% of net assets. If the Fund were to invest in a physical commodity or a physical commodity-related instrument, the Fund would be subject to the additional risks of the particular physical commodity and its related market. The value of commodities and commodity-related instruments may be extremely volatile and may be affected either directly or indirectly by a variety of factors. There also may be storage charges and risks of loss associated with physical commodities. The policy above will be interpreted to permit investments in exchange traded funds that invest in physical and/or financial commodities.

With respect to the fundamental policy relating to concentration set forth above, the 1940 Act does not define what constitutes “concentration” in an industry. The SEC staff has taken the position that investment of 25% or more of a fund’s total assets in one or more issuers conducting their

3

principal activities in the same industry or group of industries constitutes concentration. It is possible that interpretations of concentration could change in the future. A fund that invests a significant percentage of its total assets in a single industry may be particularly susceptible to adverse events affecting that industry and may be more risky than a fund that does not concentrate in an industry. The policy above will be interpreted to refer to concentration as that term may be interpreted from time to time. The policy also will be interpreted to permit investment without limit in the following: securities of the U.S. government and its agencies or instrumentalities; securities of state, territory, possession or municipal governments and their authorities, agencies, instrumentalities or political subdivisions; securities of foreign governments; and repurchase agreements collateralized by any such obligations. Accordingly, issuers of the foregoing securities will not be considered to be members of any industry. There also will be no limit on investment in issuers domiciled in a single jurisdiction or country; however, the Trust understands that the SEC staff considers securities issued by a foreign government to be in a single industry for purposes of calculating applicable limits on concentration. To the extent that the Fund invests in a private activity municipal debt security issued by a non-governmental entity, the Fund will, to the extent practicable, look through to such non-governmental issuer’s industry for purposes of applying the Fund’s concentration policy. The policy also will be interpreted to give broad authority to the Fund as to how to classify issuers within or among industries.

II. The following text replaces any information to the contrary in the section of the Funds’ SAI titled “Investment Management and Service Provider Information – Manager and Sub-Administrator”:

Manager – Small Cap Fund and Value Fund

Prior to April 1, 2024, Franklin Templeton Fund Adviser, LLC (“FTFA”) provided administrative services through its role as sub-administrator to the Funds and ClearBridge Investments, LLC (“ClearBridge”) provided investment advice through its role as manager of the Funds.

Effective April 1, 2024, FTFA (for purposes of this section and the following section, the “Manager”), serves as investment manager to the Fund and provides administrative and certain oversight services to the Fund, pursuant to an investment management agreement (for purposes of this section, the “Management Agreement”). FTFA has offices at 280 Park Avenue, New York, New York, 10017 and also serves as the investment manager of other Franklin Templeton funds. FTFA is an indirect, wholly-owned subsidiary of Franklin Resources, a Delaware corporation.

The Manager has agreed, under the Management Agreement, subject to the supervision of the Board, to provide the Fund with investment research, advice, management and supervision, furnish a continuous investment program for the Fund’s portfolio of securities and other investments consistent with the Fund’s investment objectives, policies and restrictions, and place orders pursuant to its investment determinations. The Manager is permitted to enter into contracts with subadvisers or subadministrators, subject to the Board’s approval. The Manager has entered into subadvisory agreements, as described below.

As compensation for services performed, facilities furnished and expenses assumed by the Manager, the Fund pays the Manager a fee computed daily at an annual rate of the Fund’s average daily net assets as described below.

The Management Agreement will continue in effect for its initial term and thereafter from year to year, provided continuance is specifically approved at least annually (a) by the Board or by a 1940 Act Vote, and (b) in either event, by a majority of the Independent Trustees casting votes in accordance with applicable law.

The Management Agreement provides that the Manager may render services to others. The Management Agreement is terminable without penalty by the Board or by vote of a majority of the outstanding voting securities of the Fund on not more than 60 days’ nor less than 30 days’ written notice to the Manager, or by the Manager on not less than 90 days’ written notice to the Fund as applicable, and will automatically terminate in the event of its assignment (as defined in the 1940 Act) by the Manager. No Management Agreement is assignable by the Trust except with the consent of the Manager.

The Management Agreement provides that the Manager, its affiliates performing services contemplated by the Management Agreement, and the partners, shareholders, directors, officers and employees of the Manager and such affiliates, will not be liable for any error of judgment or mistake of law, for any loss arising out of any investment, or for any act or omission in the execution of securities transactions for the Fund, but the Manager is not protected against any liability to the Fund to which the Manager would be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under the Management Agreement.

For its services under the Management Agreement, the Manager receives an investment management fee calculated daily and paid monthly according to the following schedule:

Subadviser – Small Cap Fund and Value Fund

Effective April 1, 2024, ClearBridge serves as the subadviser to the Fund (for purposes of this section, the “Subadviser”) pursuant to a subadvisory agreement between the Manager and the Subadviser (the “Subadvisory Agreement”). The Subadviser has offices at 620 Eighth Avenue, New York, New York 10018. The Subadviser is an indirect, wholly-owned subsidiary of Franklin Resources.

As compensation for its services, the Manager pays to the Subadviser a fee equal to 70% of the management fee paid to the Manager by the Fund, net of any waivers and expense reimbursements.

Effective April 1, 2024, Western Asset Management Company, LLC, organized under the laws of the State of California (“Western Asset” and together with the Subadviser, the “Subadviser”), manages the portion of the Fund’s cash and short-term instruments allocated to it pursuant to a separate subadvisory agreement between the Manager and Western Asset (the “Western Asset Agreement” and together with the Subadvisory Agreement, the “Subadvisory Agreement”). Western Asset, established in 1971, has offices at 385 East Colorado Boulevard, Pasadena, California 91101 and 620 Eighth Avenue, New York, New York 10018. Western Asset acts as investment adviser to institutional accounts, such as corporate pension plans, mutual funds and endowment funds. Western Asset is an indirect, wholly-owned subsidiary of Franklin Resources. Under the Western Asset

5

Agreement, Western Asset is responsible, subject to the general supervision of the Manager and the Board, for the management of the portion of the Fund’s cash and short term instruments allocated to it. For Western Asset’s services to the Fund, the Manager, not the Fund, pays Western Asset 0.02% of the portion of the Fund’s average daily net assets that are allocated to Western Asset by the Manager, net of expense waivers and reimbursements.

Under the Subadvisory Agreement, subject to the supervision of the Board and the Manager, the Subadviser regularly provides with respect to the portion of the Fund’s assets allocated to it by the Manager, investment research, advice, management and supervision; furnishes a continuous investment program for the allocated assets consistent with the Fund’s investment objectives, policies and restrictions; and places orders pursuant to its investment determinations. The Subadviser may delegate to companies that the Subadviser controls, is controlled by, or is under common control with, certain of the Subadviser’s duties under a Subadvisory Agreement, subject to the Subadviser’s supervision, provided the Subadviser will not be relieved of its duties or obligations under the Subadvisory Agreement as a result of any delegation.

The Subadvisory Agreement will continue in effect for its initial term and thereafter from year to year provided such continuance is specifically approved at least annually (a) by the Board or by a majority of the outstanding voting securities of the Fund (as defined in the 1940 Act), and (b) in either event, by a majority of the Independent Trustees casting votes in accordance with applicable law. The Board or a majority of the outstanding voting securities of the Fund (as defined in the 1940 Act) may terminate the Subadvisory Agreement without penalty, in each case on not more than 60 days’ nor less than 30 days’ written notice to the Subadviser. The Subadviser may terminate the respective Subadvisory Agreement, on 90 days’ written notice to the Fund and the Manager. The Subadvisory Agreement may be terminated upon the mutual written consent of the Manager and the Subadviser. The Subadvisory Agreement will terminate automatically in the event of assignment (as defined in the 1940 Act) by the applicable Subadviser, and shall not be assignable by the Manager without the consent of the Subadviser.

The Subadvisory Agreement provides that the Subadviser, its affiliates performing services contemplated by the Subadvisory Agreement, and the partners, shareholders, directors, officers and employees of the Subadviser and such affiliates will not be liable for any error of judgment or mistake of law, for any loss arising out of any investment, or for any act or omission in the execution of securities transactions for the Fund, but the Subadviser is not protected against any liability to the Fund or the Manager to which the Subadviser would be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under the Subadvisory Agreement.
