ABOUT THIS PROSPECTUS SUPPLEMENT

This document is in two parts. The first part, the prospectus supplement, describes the specific terms of the notes we are offering and certain other matters relating to Franklin Resources, Inc. The second part, the base prospectus, gives more general information about securities we may offer from time to time, some of which do not apply to the notes we are offering. Generally, when we refer to the prospectus, we are referring to both parts of this document combined. Before purchasing any notes, you should carefully read both this prospectus supplement and the accompanying base prospectus. If the description of the notes in the prospectus supplement differs from the description in the base prospectus, the description in the prospectus supplement supersedes the description in the base prospectus.

You should rely only on the information contained or incorporated by reference in this prospectus supplement and the accompanying base prospectus and in any free writing prospectus that we prepare or authorize. We have not, and the underwriters have not, authorized anyone to provide you with different or additional information. We and the underwriters take no responsibility for any other information that others may provide to you. We and the underwriters are not making an offer to sell, or seeking offers to buy, the notes in any jurisdiction where the offer and sale is not permitted. You should not assume that the information contained in this prospectus supplement, the accompanying base prospectus, any free writing prospectus and any information in the documents incorporated by reference herein and in the accompanying base prospectus is accurate as of any date other than their respective dates. Our business, financial condition, results of operations and prospects may have changed since those dates.

The distribution or possession of this prospectus supplement and the accompanying base prospectus in or from certain jurisdictions may be restricted by law. Persons into whose possession this prospectus supplement and the accompanying base prospectus come are required by us and the underwriters to inform themselves about, and to observe any such restrictions, and neither we nor any of the underwriters accepts any liability in relation thereto. See “Underwriting.”

Unless otherwise expressly stated herein or the context otherwise requires, all references in this prospectus to “Franklin Resources,” “we,” “us,” “our,” “our Company” or “the Company” refer to Franklin Resources, Inc., a Delaware corporation, and its direct and indirect subsidiaries. However, for purposes of the section entitled “Summary – The Offering” and “Description of the Notes,” whenever we refer to “Franklin Resources,” “we,” “us,” “our,” “our Company” or “the Company,” we are referring only to Franklin Resources, Inc. and not to any of its direct or indirect subsidiaries. All references in this prospectus to “Legg Mason” refer to Legg Mason, Inc., a Maryland corporation and a wholly owned subsidiary of Franklin Resources.

Unless otherwise indicated, our “funds” means the funds offered under our various brand names. We offer our services and products under our various distinct brand names, including, but not limited to, Franklin^®, Templeton^®, Balanced Equity Management^®, Benefit Street Partners^®, Darby^®, Edinburgh Partners^™, Fiduciary Trust^™, Franklin Bissett^®, Franklin Mutual Series^®, K2^®, Legg Mason^® and LibertyShares^®.

In this prospectus supplement, any amounts shown on a “pro forma as adjusted” basis have been adjusted to reflect: (i) the consummation of our acquisition of Legg Mason and (ii) the issuance of the notes in this offering.

NOTICE TO PROSPECTIVE INVESTORS IN THE EUROPEAN ECONOMIC AREA

AND THE UNITED KINGDOM

None of this prospectus supplement, the accompanying base prospectus nor any related free writing prospectus is a prospectus for the purposes of the Prospectus Regulation (as defined below). This prospectus

S-1

supplement, the accompanying base prospectus and any related free writing prospectus have been prepared on the basis that any offer of notes in any Member State of the European Economic Area (the “EEA” and each, a “Member State”) or the United Kingdom will only be made to a legal entity which is a qualified investor under the Prospectus Regulation (“Qualified Investors”). Accordingly any person making or intending to make an offer in that Member State or the United Kingdom of notes which are the subject of the offering contemplated in this prospectus supplement, the accompanying base prospectus and any related free writing prospectus may only do so with respect to Qualified Investors. Neither we nor the underwriters have authorized, nor do we or they authorize, the making of any offer of notes other than to Qualified Investors. The expression “Prospectus Regulation” means Regulation (EU) 2017/1129.

Prohibition of Sales to EEA and United Kingdom Retail Investors – The notes are not intended to be offered, sold or otherwise made available to and should not be offered sold or otherwise made available to any retail investor in the EEA or the United Kingdom. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU, as amended (“MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a Qualified Investor. Consequently no key information document required by Regulation (EU) No. 1286/2014, as amended (the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA or the United Kingdom has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA or the United Kingdom may be unlawful under the PRIIPs Regulation.

References to regulations or directives include, in relation to the United Kingdom, those regulations or directives as they form part of United Kingdom domestic law by virtue of the European Union (Withdrawal) Act 2018 or have been implemented in United Kingdom domestic law, as appropriate.

The above selling restriction is in addition to any other selling restrictions set out below.

FORWARD-LOOKING INFORMATION

Some of the statements included in this prospectus supplement, the accompanying base prospectus and the documents incorporated by reference herein and therein, may include forward-looking statements that reflect the Company’s current views with respect to future events and financial performance that are provided under the “safe harbor” protection of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include all statements that do not relate solely to historical or current facts and generally can be identified by words or phrases generally written in the future tense and/or preceded by words such as “anticipate,” “believe,” “could,” “depends,” “estimate,” “expect,” “intend,” “likely,” “may,” “plan,” “potential,” “seek,” “should,” “will,” “would,” or other similar words or variations thereof, or the negative thereof, but these terms are not the exclusive means of identifying such statements.

Forward-looking statements involve a number of known and unknown risks, uncertainties and other important factors that may cause actual results and outcomes to differ materially from any future results or outcomes expressed or implied by such forward-looking statements. The forward-looking statements contained in this prospectus supplement and the accompanying base prospectus or that are incorporated by reference herein or therein are qualified in their entirety by reference to the risks and uncertainties disclosed herein and in our filings with the SEC that are incorporated by reference herein and therein, including those discussed in such filings under the headings “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition” and “Quantitative and Qualitative Disclosures About Market Risk.”

While forward-looking statements are our best prediction at the time that they are made, you should not rely on them and are cautioned against doing so. Forward-looking statements are based on our current expectations and assumptions regarding our business, the economy and other possible future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. They are neither statements of historical fact nor guarantees or assurances of future performance. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them.

If a circumstance occurs after the date of this prospectus supplement or the date of the respective documents incorporated by reference herein that causes any of our forward-looking statements to be inaccurate, whether as a result of new information, future developments or otherwise, we undertake no obligation to announce publicly the change to our expectations, or to make any revision to our forward-looking statements, to reflect any change in assumptions, beliefs or expectations, or any change in events, conditions or circumstances upon which any forward-looking statement is based, unless required by law.

RISK FACTORS

You should carefully consider the following risks and the specific risks described in our Annual Report on Form 10-K for the fiscal year ended September 30, 2019, our subsequent Quarterly Reports on Form 10-Q and any risk factors set forth in our other filings with the SEC pursuant to Sections 13(a), 13(c) or 15(d) of the Exchange Act, which are incorporated herein by reference, before making an investment decision. Certain statements in “Risk Factors” are forward-looking statements. See “Forward-Looking Statements.”

Risks Related to the Notes

Our holding company structure results in structural subordination of our debt and may affect our ability to make payments on notes.

The notes are obligations exclusively of Franklin Resources, Inc. We are a holding company and, accordingly, substantially all of our operations are conducted through our subsidiaries. As a result, our cash flow and our ability to service our debt, including the notes, depend upon the earnings of our subsidiaries. In addition, we depend on the distribution of earnings, loans or other payments by our subsidiaries to us.

Our subsidiaries are separate and distinct legal entities. Our subsidiaries have no obligation to pay any amounts due on the notes or to provide us with funds for our payment obligations. In addition, any payment of dividends, distributions, loans or advances by our subsidiaries to us could be subject to statutory or contractual restrictions, including regulatory capital requirements. Payments to us by our subsidiaries will also be contingent upon our subsidiaries’ earnings and business considerations. Our right to receive any assets of any of our subsidiaries, as an equity holder of such subsidiaries, upon their liquidation or reorganization, and therefore the right of the holders of the notes to participate in those assets, will be effectively subordinated to the claims of that subsidiary’s creditors, including trade creditors, and to that subsidiary’s preferred stockholders, if any. The notes do not restrict the ability of our subsidiaries to incur additional indebtedness or issue preferred stock. In addition, the notes are unsecured. Thus, even if we were a creditor of any of our subsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of our subsidiaries and any indebtedness of our subsidiaries senior to that held by us.

As of June 30, 2020, on a pro forma basis to reflect our acquisition of Legg Mason, our subsidiaries had $2,324.4 million of indebtedness outstanding. The indebtedness of Legg Mason is recorded on a pro forma basis at its fair value as of the date of our acquisition of Legg Mason, and it includes a $324.4 million premium over the $2,000.0 million aggregate principal amount of the indebtedness of Legg Mason.

The notes are unsecured.

The notes are unsecured. The indenture for the notes does not restrict our ability to incur additional indebtedness, including secured indebtedness generally. Holders of any secured indebtedness will have claims that are prior to your claims as holders of the notes, to the extent of the value of the assets securing such indebtedness, in the event of any bankruptcy, liquidation or similar proceeding involving us.

We may issue additional notes.

Under the terms of the indenture, we may from time to time without notice to, or the consent of, the holders of the notes, create and issue additional notes of a new or existing series, which notes, if of an existing series, will be equal in rank to the notes of that series in all material respects, and the new notes may be consolidated and form a single series with such notes and have the same terms as to status, redemption or otherwise as such notes; provided that, any such additional notes shall be issued under a separate CUSIP or ISIN number unless the additional notes are issued pursuant to a “qualified reopening” of the existing series, are otherwise treated as part of the same “issue” of debt securities as the existing series or are issued with no more than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

S-12

The notes do not restrict our ability to incur additional debt or to take other actions that could negatively affect holders of the notes.

We are not restricted under the terms of the notes from incurring additional unsecured indebtedness, including other senior indebtedness or secured indebtedness. In addition, the limited covenants applicable to the notes do not restrict our ability to pay dividends, issue or repurchase stock or other securities, granting security interests over our assets or require us to achieve or maintain any minimum financial results relating to our financial position or results of operations. In addition, the notes will not be subject to redemption or repurchase upon a change of control. Our ability to recapitalize, incur additional debt and take a number of other actions that are not limited by the terms of the notes could have the effect of diminishing our ability to make payments on the notes when due. Although the notes do not contain such financial and other restrictive covenants, future indebtedness could include such covenants. If we incur additional indebtedness or other liabilities, our ability to pay our obligations on our outstanding indebtedness could be adversely affected.

There is no public market for the notes.

We have not applied and do not intend to apply for listing of the notes on any securities exchange or automated quotation system. As a result, we can give no assurances concerning the liquidity of any market that may develop for the notes offered hereby, your ability to sell the notes, or the price at which you would be able to sell them. If a market for the notes does not develop, you may be unable to resell the notes for an extended period of time, if at all. If a market for the notes does develop, it may not continue or it may not be sufficiently liquid to allow holders to resell any of the notes. Consequently, you may not be able to liquidate your investment readily, and lenders may not readily accept the notes as collateral for loans.

The market price of the notes may be volatile.

The market price of the notes will depend on many factors that may vary over time and some of which are beyond our control, including our financial performance, the amount of indebtedness we and our subsidiaries have outstanding, market interest rates, the market for similar securities, competition and general economic conditions. The capital and credit markets continue to experience volatility and disruption worldwide.

As a result of these factors, you may only be able to sell your notes at a price below that you believe to be appropriate, including a price below the price you paid for them.

An increase in interest rates could result in a decrease in the relative value of the notes.

In general, as market interest rates rise, notes bearing interest at a fixed rate generally decline in value because the premium, if any, over market interest rates will decline. Consequently, if you purchase the notes and market interest rates increase, the market value of your notes may decline. We cannot predict the future level of market interest rates.

Ratings of the notes may not reflect all risks of an investment in the notes.

We expect that the notes will be rated by at least one nationally recognized statistical rating organization. Credit ratings are limited in scope, and do not address all material risks to an investment in the notes, and only reflect the view of a rating organization at the time the rating is issued. We can provide no assurance that a credit rating will remain in effect for any period of time or that a rating will not be lowered, suspended or withdrawn by the applicable rating organization if, in such organization’s judgment, circumstances so warrant. Any rating is not a recommendation to purchase, sell, or hold the notes. The ratings do not correspond to market price or suitability for a particular investor. In addition, actual or anticipated changes or downgrades of our credit ratings, including any announcement that our ratings are under review for a downgrade, could affect the market prices or marketability of the notes and increase our borrowing costs.

Redemption may adversely affect your return on the notes.

We have the right to redeem some or all of the notes prior to maturity, as described under “Description of the Notes—Optional Redemption” in this prospectus supplement. We may redeem the notes at times when

S-13

prevailing interest rates may be relatively low. Accordingly, you may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as that of the notes.

Risks Related to the Company

Our business is subject to uncertainties and risks. You should carefully consider and evaluate all of the information included and incorporated by reference in this prospectus supplement, including the section entitled “Risk Factors” incorporated by reference from our most recent Annual Report on From 10-K, Quarterly Reports on Form 10-Q and other SEC filings filed after such annual report.

Our business and operations are subject to adverse effects from the outbreak and spread of contagious diseases such as COVID-19, and we expect such adverse effects to continue.

The outbreak and spread of contagious diseases such as the novel coronavirus (“COVID-19”), a highly transmissible and pathogenic disease, has adversely affected, and we expect will continue to adversely affect, our business, financial condition and results of operations. The COVID-19 pandemic has resulted and will likely continue to result in a widespread national and global public health crisis. Such infectious illness outbreaks or other adverse public health developments in countries where we operate, as well as local, state and/or national government restrictive measures implemented to control such outbreaks, could adversely affect the economies of many nations or the entire global economy, the financial condition of individual issuers or companies and capital markets, in ways that cannot necessarily be foreseen, and such impacts could be significant and long term. Such extraordinary events and their aftermaths can cause investor fear and panic, which can further adversely affect the operations and performance of companies, sectors, nations, regions and financial markets in general and in ways that cannot necessarily be foreseen. The COVID-19 pandemic has already adversely affected and will likely continue to adversely affect global economies and markets, and has resulted in a global economic downturn and disruptions in commerce that will continue to evolve, including with respect to financial and other economic activities, services, travel and supply chains. Global and national health concerns, and uncertainty regarding the impact of COVID-19, could lead to further and/or increased volatility in global capital and credit markets, adversely affect our key executives and other personnel, clients, investors, providers, suppliers, lessees, and other third parties, and negatively impact our AUM, revenues, income, business and operations.

Our business has been and will likely continue to be negatively impacted by the current COVID-19 pandemic, including by the potential reoccurrence of periods of increased spread of COVID-19, and ensuing economic downturn in global financial markets. The global spread of COVID-19, and the various governmental actions and economic effects related to the pandemic, have had, and are expected to continue to have, negative impacts on our business and operations, including volatility in asset values, reduced demand for our products and services, concerns for and restrictions on our personnel (including health concerns, quarantines, shelter-in-place orders and restrictions on travel), and increased cybersecurity risks. Past economic downturns have caused, and the current economic downturn is causing and is expected to continue to cause, periods of significant volatility in our stock price, decreases and fluctuations in our AUM, revenues and income, increased liquidity risks and redemptions in our funds and other products (which could result in difficulties obtaining cash to settle redemptions), poor investment performance of our products and corporate investments, increased focus on expense management, capital resources and related planning, and could cause reputational harm, legal claims, and other factors that may arise or develop. Current increased liquidity risks and redemptions in our funds and other products have required, and may continue to require, increased cash in the form of loans or other lines of credit for them to draw on to help settle redemptions and for other related purposes. We have in some cases voluntarily determined to, and without obligation could in the future, extend such loans. In addition, such increased liquidity risks and redemptions have caused, and could continue to cause, fund closures, and related regulatory and governmental reviews or investigations and legal claims or actions subject us to legal and regulatory risks and potential financial exposure.

Our business operations are complex and conducted in numerous countries around the globe, and in order to remain competitive, we must continue to perform our asset management and related business responsibilities for

S-14

our clients and investors properly and effectively throughout the course of the COVID-19 pandemic, which, among other matters, is dependent on the health and safety of our personnel, the ability of our personnel to work remotely successfully, and our ability to have our personnel return to work at our offices safely and effectively in compliance with applicable requirements. We have implemented our business continuity plans globally to manage our business during this pandemic, including broad and extended work-from-home capabilities for our personnel where feasible and, as governmental shelter-in-place restrictions have been lifted in various jurisdictions, we have implemented measures for the return of a portion of our personnel to certain of our offices. We can provide no assurance that our efforts and planning for either environment will be sufficient to protect the health and safety of our personnel and maintain the success of our business. Further, we depend on a number of third-party providers to support our operations, and any failure of our providers to fulfill their obligations could adversely impact our business. Moreover, we now have an increased dependency on remote equipment and connectivity infrastructure to access critical business systems that may be subject to failure, disruption or unavailability that could negatively impact our business operations. Additionally, multiple regions in which we operate have shelter-in-place movement restrictions on our personnel and third-party vendors and service providers that may impact our ability to satisfy or respond timely to potential technology issues or needs impacting our business and operations. Further, we, like many others during this time, have been subject to an increase in phishing and other social engineering attempts by malicious actors to manipulate individuals into divulging confidential or personal information. If our cybersecurity diligence and efforts to offset the increased risks associated with greater reliance on mobile, collaborative and remote technologies during this health crisis are not effective or successful, we may be at increased risk for cybersecurity or data privacy incidents.

Any inability to recover successfully following the COVID-19 pandemic with respect to the economic, investment or operational impacts to our company or industry could further negatively impact our business and operations. As of the time of this filing, as the COVID-19 pandemic continues to evolve, it is not possible to predict the extent to which the coronavirus will adversely impact our business, liquidity, capital resources, financial results and operations, which impacts will depend on numerous developing factors that are highly uncertain and rapidly changing. The impacts and risks described herein relating to COVID-19 augment the discussion of overlapping risks in our risk factors incorporated by reference from our recent Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and other SEC filings filed after such annual report.

Regulatory and governmental examinations and/or investigations, litigation and the legal risks associated with our business, could adversely impact our AUM, increase costs and negatively impact our profitability and/or our future financial results.

We operate in a highly-regulated industry and routinely receive and respond to regulatory and governmental requests for documents or other information, subpoenas, examinations and investigations in connection with our business activities. In addition, from time to time, we are named as a party in litigation. Even if claims made against us are without merit, litigation typically is an expensive process. Risks associated with legal liability often are difficult to assess or quantify and their existence and magnitude can remain unknown for significant periods of time. Eventual financial exposures from and expenses incurred relating to any examinations, investigations, litigation, and/or settlements could adversely impact our AUM, increase costs and/or negatively impact our profitability and financial results. Allegations, findings or judgments of wrongdoing by regulatory or governmental authorities or in litigation against us, or settlements with respect thereto, could affect our regulatory licenses, reputation, increase our costs of doing business and/or negatively impact our revenues, any of which could have a material negative impact on our financial results.

Effective April 24, 2020, a subsidiary of Franklin, Franklin Templeton Trustee Services Private Limited (“FTTS”), announced its decision to wind up six fixed income mutual fund schemes of the Franklin Templeton Mutual Fund in India (referred to herein as the “Funds” or the “India Fixed Income Funds”), which at the time had collective assets under management of approximately USD $3.4 billion. FTTS took action to convene unitholder meetings for the Funds to approve the appointment of liquidators as required by law, and the asset management company to the Funds, Franklin Templeton Asset Management (India) Private Limited (“FTAMI”),

S-15

ceased earning investment management fees on the Funds. Certain unitholders and others subsequently commenced multiple writ petition actions in India (some of which have since been dismissed) challenging the decision to wind up the Funds and alleging that the Company respondents violated various regulations of the Securities and Exchange Board of India (“SEBI”), mismanaged the Funds, misrepresented or omitted certain information relating to the Funds, and engaged in other alleged misconduct. The petitioners seek a wide range of relief, including, among other items, an order quashing the windup notice and blocking the unitholder voting process, directing regulatory and governmental entities to initiate investigations into the Company respondents, and allowing the unitholder petitioners to redeem their investments with interest.

On June 3, 2020, the High Court of Gujarat granted an ex parte interim injunction order staying the operation and implementation of the unitholder voting process. On June 19, 2020, all of the petitions were transferred to the High Court of Karnataka for hearing and resolution. In the course of the hearings, on September 24, 2020, the Company learned that a “first information report” or “FIR” had been registered by the Economic Offenses Wing of the Chennai police department against certain of the Company respondents in connection with a complaint made by one of the petitioners in the action. In light of the registration of the FIR, which is the preliminary step in an investigation, the court disposed of the petition that had sought an order for such an investigation. Hearings before the court on all of the petitions concluded on September 24, 2020, and the matters are now under submission with the court for its judgment.

Separately, on May 27, 2020, SEBI initiated a forensic audit/inspection of the Franklin Templeton Mutual Fund, FTAMI, and FTTS and appointed an outside auditor to conduct the review. The auditor submitted a confidential report to SEBI containing certain observations, to which SEBI sought responses from FTAMI and FTTS and such responses were provided in September 2020. The matter is currently under review by SEBI.

Management strongly believes that the petitions are without merit, and that the decision to wind up the India Fixed Income Funds was taken in the best interests of investors and fully pursuant to applicable SEBI regulations. Nonetheless, a judgment voiding the windup determination, if not stayed pending any appeal and ultimately reversed, could lead to significant redemption pressures on the Funds. If the Funds are unable to meet all investor redemption requests or to meet them in an orderly fashion, additional litigation and/or regulatory or governmental investigations and proceedings could be initiated. In addition, if the SEBI were to commence a regulatory proceeding in connection with the audit and ultimately conclude that the respondents violated applicable regulations, it is possible that certain Company subsidiaries and related individuals could be subject to the imposition of regulatory sanctions. While the Company believes that it would have meritorious defenses to any such actions, such matters could involve risk of significant financial penalties and other liabilities, reputational harm, and restrictions on the Company’s asset management activities in India, all of which could adversely impact the Company’s financial results. The Company cannot at this time predict the eventual outcome of the matters described above or reasonably estimate the possible loss or range of loss that may arise from any negative outcome of such matters, including due to the current stage of these matters.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Summary of Transaction

On July 31, 2020, Franklin Resources completed its acquisition of Legg Mason (the “Acquisition”) pursuant to the terms and conditions of the Merger Agreement. The EnTrust business was acquired by its management concurrent with the closing of the Acquisition.

The foregoing description of the Acquisition is qualified in its entirety by reference to the full text of the Merger Agreement, which was filed as Exhibit 2.1 to the Company’s Current Report on Form 8-K on February 18, 2020.

Pro Forma Information

The unaudited pro forma condensed combined statements of income for the fiscal year ended September 30, 2019 and the nine months ended June 30, 2020 combine the historical consolidated statements of income of Franklin Resources and Legg Mason, giving effect to the Acquisition as if it had occurred on October 1, 2018. The unaudited pro forma condensed combined balance sheet as of June 30, 2020 combines the historical consolidated balance sheets of Franklin Resources and Legg Mason, giving effect to the Acquisition as if it had occurred on June 30, 2020.

The unaudited pro forma condensed combined financial information (“pro forma information”) is based on, and should be read in conjunction with, the following historical consolidated financial statements and accompanying notes:

Franklin Resources and Legg Mason have differing fiscal years. Franklin Resources’ fiscal year end is September 30 and, prior to the closing of the Acquisition, Legg Mason’s fiscal year end was March 31. The Legg Mason results of operations included in the unaudited pro forma condensed combined statements of income reflect the results for the nine months ended June 30, 2020 and the year ended September 30, 2019 as derived from Legg Mason’s previously reported results of operations. See Note 4 – Legg Mason Results of Operations for further information.

Certain reclassifications have been made to the historical consolidated statements of income and consolidated balance sheet of Legg Mason to align their presentation in the pro forma information to Franklin Resources’ presentation. See Note 5 – Reclassifications for further information.

S-19

The historical consolidated financial information has been adjusted in the pro forma information to give effect to pro forma events that are directly attributable to the Acquisition, factually supportable, and with respect to the unaudited pro forma condensed combined statements of income, expected to have a continuing impact on the combined results of operations of more than one year.

The pro forma information has been prepared using the acquisition method of accounting in accordance with accounting principles generally accepted in the United States of America. The acquisition method of accounting is dependent upon certain valuations that are provisional and subject to change. The pro forma adjustments are based on the assumptions and information available at the time of the filing of our Current Report on Form 8-K/A on October 6, 2020. Franklin Resources will finalize the acquisition accounting within the required measurement period, but no later than July 31, 2021.

The unaudited pro forma condensed combined statements of income do not reflect any potential cost savings or synergies that may be realized as a result of the Acquisition and also do not reflect any integration-related costs to achieve those potential cost savings or synergies. The integration-related costs will continue to be expensed as incurred in the appropriate accounting periods following completion of the Acquisition. Although Franklin projects that cost savings and synergies will result from the Acquisition, there can be no assurance that they will be achieved and such potential cost savings or synergies are subject to risks, uncertainties and other factors. For a detailed discussion of these risk factors, please refer to the risk, uncertainties and other factors described in the Company’s filings with the Securities and Exchange Commission. There were no material transactions between Franklin Resources and Legg Mason during the periods presented in the pro forma information.

The pro forma information should be read in conjunction with the accompanying notes to the pro forma information. The pro forma information is not necessarily indicative of what the financial position or results of operations would have been had the Acquisition occurred as of the dates indicated nor does it project the future financial position or operating results of the combined company.

FRANKLIN RESOURCES, INC.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Note 1 – Description of Transaction

On July 31, 2020, Franklin Resources, Inc. (the “Company” or “Franklin”) completed its acquisition (the “Acquisition”) of Legg Mason, Inc. (“Legg Mason”) pursuant to the terms and conditions of the Agreement and Plan of Merger (the “Merger Agreement”), dated as of February 17, 2020, by and among the Company, Legg Mason and Alpha Sub, Inc. (“Merger Sub”).

Pursuant to the Merger Agreement, on July 31, 2020, Merger Sub merged with and into Legg Mason (the “Merger”), with Legg Mason surviving the Merger as a wholly-owned subsidiary of the Company. At the effective time of the Merger (the “Effective Time”), each outstanding share of common stock, par value $0.10 per share of Legg Mason (the “Legg Mason Common Stock”), other than shares directly owned and held by the Company or Merger Sub, was cancelled, retired and converted into the right to receive $50.00 in cash, without interest (the “Merger Consideration”).

In addition, all issued and outstanding options (the “Legg Mason Options”) to purchase shares of Legg Mason Common Stock were automatically terminated and cancelled at the Effective Time and each holder of Legg Mason Options with a per share exercise price that was less than the Merger Consideration became entitled to receive a lump sum cash payment (less any applicable withholding taxes) in an amount equal to the product of (A) the number of shares of Legg Mason Common Stock underlying such Legg Mason Options, and (B) an amount equal to the Merger Consideration minus the applicable exercise price of such Legg Mason Options.

All issued and outstanding or payable restricted stock units in respect of Legg Mason Common Stock (the “Legg Mason RSUs”) were automatically terminated and cancelled at the Effective Time and each holder of a Legg Mason RSU became entitled to receive a lump sum cash payment (less any applicable withholding taxes) in an amount equal to (A) the product of (i) the Merger Consideration and (ii) the number of shares of Legg Mason Common Stock subject to such Legg Mason RSU, plus (B) any accrued but unpaid dividend equivalent rights in respect of such Legg Mason RSUs.

All issued and outstanding or payable performance restricted stock units in respect of Legg Mason Common Stock (the “Legg Mason PSUs”) were automatically terminated and cancelled at the Effective Time and each holder of a Legg Mason PSU became entitled to receive a lump sum cash payment (less any applicable withholding taxes) in an amount equal to the product of (A) the Merger Consideration and (B) the target number of shares of Legg Mason Common Stock subject to such Legg Mason PSUs.

The EnTrust business (the “Divested Business”) was acquired by its management concurrent with the closing of the Acquisition in exchange for future cash payments not to exceed $50.0 million.

The foregoing description of the Acquisition does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which was filed as Exhibit 2.1 to the Company’s Current Report on Form 8-K on February 18, 2020.

Note 2 – Basis of Presentation

Pro Forma Presentation

The unaudited pro forma condensed combined financial information (“pro forma information”) has been prepared in accordance with Article 11, Pro Forma Financial Information, under Regulation S-X of the Securities and Exchange Act of 1934 (the “Exchange Act”), and is for informational purposes only. Certain reclassifications have been made to the historical statements of Legg Mason to conform to Franklin’s presentation, which are discussed in more detail in Note 5 – Reclassifications.

S-24

The unaudited pro forma condensed combined statements of income for the fiscal year ended September 30, 2019 and the nine months ended June 30, 2020 combine the historical consolidated statements of income of Franklin and Legg Mason, giving effect to the Acquisition as if it had occurred on October 1, 2018. The unaudited pro forma condensed combined balance sheet as of June 30, 2020 combines the historical consolidated balance sheets of Franklin and Legg Mason, giving effect to the Acquisition as if it had occurred on June 30, 2020.

The historical consolidated financial information has been adjusted in the pro forma information to give effect to pro forma events that are directly attributable to the Acquisition, factually supportable, and with respect to the unaudited pro forma condensed combined statements of income, expected to have a continuing impact on the results of operations of the combined company of more than one year.

The pro forma information has been prepared using the acquisition method of accounting in accordance with accounting principles generally accepted in the United States of America. Under the acquisition method of accounting, the Acquisition is accounted for by recognizing the acquired assets, including separately identifiable intangible assets, and assumed liabilities at their acquisition-date fair values. Any excess of the purchase consideration over the acquisition-date fair values of these identifiable assets and liabilities is recognized as goodwill. The pro forma adjustments are based upon the assumptions and information available at the time of the preparation of our Current Report on Form 8-K/A filed on October 6, 2020 and may be subject to change. The Company will finalize the acquisition accounting within the required measurement period, but no later than July 31, 2021. Differences between these estimates of fair value and the final acquisition accounting may occur, and those differences could have a material impact on the pro forma information and the combined company’s future results of operations and financial position. At the time of the filing of the Form 8-K/A on October 6, 2020, the Company does not expect material changes to the assets acquired or liabilities assumed, with the exception of deferred tax assets and liabilities which were valued using preliminary assumptions.

The unaudited pro forma condensed combined statements of income do not reflect any potential cost savings or synergies that may be realized as a result of the Acquisition and also do not reflect any integration-related costs to achieve those potential cost savings or synergies. Integration-related costs will continue to be expensed as incurred in the appropriate accounting periods following completion of the Acquisition. Although Franklin projects that cost savings and synergies will result from the Acquisition, there can be no assurance that they will be achieved and such potential cost savings or synergies are subject to risks, uncertainties and other factors. For a detailed discussion of these risk factors, please refer to the risk, uncertainties and other factors described in the Company’s filings with the Securities and Exchange Commission. There were no material transactions between Franklin and Legg Mason during the periods presented in the pro forma information.

Accounting policies

Franklin has completed the review of Legg Mason’s detailed accounting policies and concluded that the differences between the accounting policies of the two companies are not material. The accounting policies used in the presentation of the pro forma information are those disclosed in Franklin’s audited consolidated financial statements for the fiscal year ended September 30, 2019. Certain reclassifications of amounts contained in Legg Mason’s historical financial statements have been made to conform to Franklin’s presentation. See Note 5 – Reclassifications for further information.

Note 3 – Estimated Fair Value of Assets Acquired and Liabilities Assumed

The unaudited pro forma condensed combined financial information includes various assumptions, including those related to the preliminary purchase price allocation of the assets acquired and liabilities assumed from Legg Mason based on management’s best estimates of fair value. The final purchase price allocation may vary based on final valuations and analyses of the fair value of the acquired assets and assumed liabilities. Accordingly, the pro forma adjustments are preliminary.

S-25

The components of the consideration transferred to effect the Acquisition are as follows:

The following table shows the preliminary allocation of the purchase price for Legg Mason to the acquired identifiable assets, assumed liabilities and pro forma goodwill.

The intangible assets relate to acquired investment management contracts and trade names. Indefinite-lived intangible assets represent contracts for which there is no foreseeable limit on the contract period. Definite-lived intangible assets are amortized over their estimated useful lives, which range from 5.0 years to 7.0 years for those related to the contracts and 5.0 years to 20.0 years for those related to trade names. The definite-lived intangible assets related to the contracts and trade names have estimated weighted-average useful lives of 5.9 years and 14.5 years, respectively.

The debt of Legg Mason has a maturity value of $2,000.0 million and is recorded at fair value on acquisition date. The acquisition-date fair value includes a premium of $324.4 million which will be amortized as a reduction to interest expense over the remaining terms of the notes.

Note 4 – Legg Mason Results of Operations

The Company and Legg Mason have differing fiscal years. The Company’s fiscal year end is September 30 and, prior to the closing of the Acquisition, Legg Mason’s fiscal year end was March 31. The Legg Mason results

of operations included in the unaudited pro forma condensed combined statements of income reflect the results for the nine months ended June 30, 2020 and the year ended September 30, 2019 as derived from Legg Mason’s previously reported results of operations, calculated as follows:
