ClearBridge Small Cap Growth Fund III

Fund overview

Q. What is the Fund’s investment strategy?

A. The Fund seeks long-term growth of capital. Under normal circumstances, the Fund invests at least 80% of its assets in equity securities of companies with small market capitalizations and related investments. We use a growth-oriented investment style that emphasizes small U.S. companies. Some of the sought characteristics for individual security selection include:

• Superior management teams

• Good prospects for growth

• Predictable, growing demand for their products or services

• Dominant position in a niche market or customers that are very large companies

• Earnings and revenue recovery potential due to exposure to economical cyclical end markets

• Strong or improving financial conditions

In addition, the Fund may invest in companies that we believe to be emerging in new or existing markets.

The Fund may invest in companies we believe to be undervalued relative to their peers. The Fund may continue to hold securities of issuers that become medium capitalization or large capitalization issuers if, in our judgment, these securities remain good investments for the Fund.

We generally use a “bottom-up” approach when selecting securities for the Fund. We focus on individual security selection rather than allow macro-economic considerations to strongly influence sector weights or individual security selection.

The Fund expects that, under normal market conditions the equity securities in which it invests will typically be common stocks. The Fund may invest up to 20% of its net assets in equity securities of companies that are not considered to be small capitalization companies. The Fund may invest up to 20% of its assets in non-convertible bonds, notes and debt. The Fund may invest up to 20% of its net assets (at the time of investment) in foreign securities. The Fund may invest directly in foreign issuers or invest in depositary receipts.

Q. What were the overall market conditions during the Fund’s reporting period?

A. Positive performance for the S&P 500 Indexⁱ, which advanced 10.14% for the twelve months ended October 31, 2023, overlooked broader weakness across the rest of the U.S. equity market. Tightening financial conditions, sparked by aggressive interest rate increases by the Federal Reserve Board (the “Fed”) and the failure of two regional banks, weighed heavily on smaller cap companies with the Russell 2000 Indexⁱⁱ returning -8.56% for the reporting period. Small cap growth stocks held up better than their value counterparts but still suffered losses with the benchmark Russell 2000 Growth Indexⁱⁱⁱ returning -7.63% while

ClearBridge Small Cap Growth Fund 2023 Annual Report 1

Fund overview (cont’d)

the Russell 2000 Value Index^iv returned -9.93%. Within the benchmark, the defensive consumer staples (+9.81%) and energy (+0.17%) sectors as well as the artificial intelligence (AI) enthusiasm-supported information technology (“IT”) (+1.05%) sector outperformed along with industrials (+0.90%). Meanwhile, the normally resilient health care sector (-18.21%) was the worst performer while materials (-14.23%) and communication services (-10.44%) also underperformed.

Initial signs of progress in the Fed’s efforts to tame generationally high inflation supported equities in the fourth quarter of 2022 and the first quarter of 2023, with strong performance among defensive and cyclical¹ stocks.

In March, markets focused on the U.S. banking system after significant market losses in Silicon Valley Bank’s securities portfolio spurred a run on the bank’s deposits and resulted in the second-largest bank failure in U.S. history. This sparked a crisis of confidence across small and midsize regional banks, as consumers shifted their deposits to larger banks perceived to be more stable. Although contagion concerns had eased by the end of the month, the crisis intensified concern over the probability and severity of a recession as banks are likely to tighten lending standards.

Stocks rose in the second quarter as investors took cooling inflation to mean the Fed’s tightening cycle was nearing its conclusion. Simultaneously, enthusiasm grew over the potential applications and benefits of AI. The result was positive overall market performance with gains particularly concentrated in a handful of mega cap companies in the IT, consumer discretionary and communication services sectors.

Market leadership began to broaden by the beginning of the third quarter as better-than-expected corporate earnings and cooling inflation created a growing chorus for a soft landing for the economy (rather than a recession). This helped provide a bid to smaller and more economically sensitive stocks on the hopes that the Fed would reach its rate hike zenith, or even reduce rates, before the end of the year. However, as the quarter wore on, stubborn inflationary data, continued economic resiliency and surging Treasury yields pushed out rate cut expectations further into the future.

Q. How did we respond to these changing market conditions?

A. In addition to the latest reporting period ended October 31, 2023, the Fund has had three prior periods of significant underperformance. Those occurred during the second half of 2008, the first half of 2015 and most recently the fourth quarter of 2020 into early 2021. Needless to say, we are disappointed and frustrated during these periods of subpar performance. Yet the small cap growth market (and the broader equity market) sometimes moves in mysterious ways during concentrated timeframes.

¹  Cyclical consists of the following industries: automotive, entertainment, gaming, home construction, lodging, retailers, restaurants, textiles and other consumer services.

2 ClearBridge Small Cap Growth Fund 2023 Annual Report

We have found that sticking to our investment disciplines has led to a relative performance recovery for our clients. We have continued to exercise judgment and patience to ensure we have 1) the right balance of opportunity and risk in the Fund, and 2) properly capitalized investments with substantial intermediate- to long-term growth opportunities. Our activity during the year was guided by these principles, leading to fourteen new investments that remained in the Fund at the end of the reporting period.

One positive during the year was the reopening of the new issues market after a near standstill during the throes of the COVID-19 pandemic and recovery. We participated in the initial public offerings of Klaviyo, a software and database platform that provides marketing automation solutions primarily to smaller e-commerce customers that we had owned as a private placement, and Oddity Tech, an already profitable direct to consumer cosmetics business that uses AI and related technologies to connect with customers.

Another notable addition was BWX Technologies, a manufacturer of naval reactors and components for the U.S. Navy and commercial players. With roughly 80% of revenues tied to a highly visible & well-funded defense priority (nuclear submarines), the company should drive steady and defensive growth with multiple upside drivers from greater acceptance of nuclear energy’s role in the energy transition coupled with technology advances in micro-reactors and small modular reactors.

We also exited sixteen positions for both positive and negative reasons. On the constructive side, several stocks were the targets of acquisitions (New Relic, Syneos Health, AeroJet RocketDyne) while one increased in value out of the Fund’s market cap range (HubSpot). We were expeditious in selling out of names due to new risks, such as the regional banking crisis in March that negatively impacted Western Alliance Bancorp, as well as the early August revelation that the GLP-1 diabetes and obesity treatments had potentially important cardiovascular benefits which led to pervasive selling of a plethora of medical technology stocks. In response to the negative sentiment across the health care sector, we closed out of Silk Road Medical and STAAR Surgical. Similarly, the threat of disintermediation from AI led us to exit online education provider Chegg.

A combination of idiosyncratic individual stock moves, a lower-quality small cap rally and Russell index rebalancing were among the main drivers of underperformance during the year. We have taken appropriate repositioning moves as described above while reaffirming the long-term appeal of many of the short-term stock underperformers. As such, we maintain meaningful exposure to software and semiconductor stocks in IT and non-therapeutic areas of health care.

Performance review

For the twelve months ended October 31, 2023, Class A shares of ClearBridge Small Cap Growth Fund, excluding sales charges, returned -13.09%. The Fund’s unmanaged benchmark, the Russell 2000 Growth Index, returned -7.63% for the same period.

The performance shown represents past performance. Past performance is no guarantee of future results and current performance may be higher or lower than the performance shown above. Principal value and investment returns will fluctuate and investors’ shares, when redeemed, may be worth more or less than their original cost. To obtain performance data current to the most recent month-end, please visit our website at www.franklintempleton.com.

All share class returns assume the reinvestment of all distributions at net asset value and the deduction of all Fund expenses. Returns have not been adjusted to include sales charges that may apply or the deduction of taxes that a shareholder would pay on Fund distributions. If sales charges were reflected, the performance quoted would be lower. Performance figures for periods shorter than one year represent cumulative figures and are not annualized.

Fund performance figures reflect fee waivers and/or expense reimbursements, without which the performance would have been lower.

 Total Annual Operating Expenses (unaudited)

As of the Fund’s current prospectus dated March 1, 2023, gross total annual fund operating expense ratios for Class 1, Class A, Class C, Class FI, Class R, Class I and Class IS shares were 0.89%, 1.18%, 1.99%, 1.20%, 1.48%, 0.90% and 0.78%, respectively.

Actual expenses may be higher. For example, expenses may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile.

Q. What were the leading contributors to performance?

A. Relative to the benchmark, overall sector allocation contributed to performance for the reporting period. In particular, an overweight allocation to the consumer staples sector and underweights to the energy and health care sectors were the primary driver of results.

Leading individual stock contributors included positions in XPO in the industrials sector, Hamilton Lane in the financials sector, Monolithic Power Systems in the IT sector, Casey’s General Stores in the consumer staples sector and ICON in the health care sector.

¹  Class 1 shares of the Fund are closed to all purchases or incoming exchanges. Investors owning Class 1 may continue to maintain their then-current Class 1 shares, but are no longer permitted to add to their Class 1 share positions, except through dividend reinvestment.

Q. What were the leading detractors from performance?

A. Relative to the benchmark, overall stock selection had a negative impact on performance. In particular, stock selection in the consumer discretionary, consumer staples, industrials, health care, IT and communication services sectors detracted the most from performance for the year.

The leading detractors from performance for the period included National Vision Holdings in the consumer discretionary sector, Silk Road Medical in the health care sector, Western Alliance Bancorp and Trupanion in the financials sector and Xometry in the industrials sector.

Q. Were there any significant changes to the Fund during the reporting period?

A. The largest additions to the Fund’s portfolio were Element Solutions and Livent in the materials sector, Integral Ad Science Holding in the communication services sector, Definitive Healthcare in the health care sector and BWX Technologies in the industrials sector. The largest positions closed during the period were Silk Road Medical, Syneos Health and STAAR Surgical in the health care sector, New Relic in the IT sector and Western Alliance Bancorp in the financials sector.

RISKS: Equity securities are subject to price and market fluctuations. Investments in small- and medium-capitalization companies may involve a higher degree of risk and volatility than investments in larger, more established companies. Investments in foreign securities are subject

ClearBridge Small Cap Growth Fund 2023 Annual Report 5

Fund overview (cont’d)

to certain risks of overseas investing, including currency fluctuations and changes in political, social and economic conditions, which could result in significant market fluctuations. These risks are magnified in emerging markets. Emerging market countries tend to have economic, political, and legal systems that are less developed and are less stable than those of more developed countries. The Fund may use derivatives, such as options and futures, which can be illiquid, may disproportionately increase losses, and have a potentially large impact on Fund performance. The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to changes in general market conditions, overall economic trends or events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes or other factors, political developments, armed conflicts, economic sanctions and countermeasures in response to sanctions, major cybersecurity events, investor sentiment, the global and domestic effects of a pandemic, and other factors that may or may not be related to the issuer of the security or other asset. Please see the Fund’s prospectus for a more complete discussion of these and other risks and the Fund’s investment strategies.

Fund expenses (unaudited)

Example

As a shareholder of the Fund, you may incur two types of costs: (1) transaction costs, including front-end and back-end sales charges (loads) on purchase payments; and (2) ongoing costs, including management fees; service and/or distribution (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

This example is based on an investment of $1,000 invested on May 1, 2023 and held for the six months ended October 31, 2023.

Actual expenses

The table below titled “Based on actual total return” provides information about actual account values and actual expenses. You may use the information provided in this table, together with the amount you invested, to estimate the expenses that you paid over the period. To estimate the expenses you paid on your account, divide your ending account value by $1,000 (for example, an $8,600 ending account value divided by $1,000 = 8.6), then multiply the result by the number under the heading entitled “Expenses Paid During the Period”.

Hypothetical example for comparison purposes

The table below titled “Based on hypothetical total return” provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio and an assumed rate of return of 5.00% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use the information provided in this table to compare the ongoing costs of investing in the Fund and other funds. To do so, compare the 5.00% hypothetical example relating to the Fund with the 5.00% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table below are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as front-end or back-end sales charges (loads). Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transaction costs were included, your costs would have been higher.

The Russell 2000 Growth Index (the “Index”) measures the performance of the small-cap growth segment of the U.S. equity universe. It includes those Russell 2000 Index companies with higher price-to value ratios and higher forecasted growth values. The Index is unmanaged and is not subject to the same management and trading expenses as a mutual fund. Please note that an investor cannot invest directly in an index. The performance of the Fund’s other classes may be greater or less than the Class A and C shares’ performance indicated on this chart depending on whether greater or lesser sales charges and fees were incurred by shareholders investing in the other classes.

In the absence of compensating balance arrangements, fee waivers and/or expense reimbursements, the total return would have been lower. Past performance is no guarantee of future results.

³  As a result of an expense limitation arrangement, the ratio of total annual fund operating expenses, other than interest, brokerage commissions, taxes, extraordinary expenses and acquired fund fees and expenses, to average net assets of Class 1 shares did not exceed the ratio of total annual fund operating expenses of Class A shares. This expense limitation arrangement cannot be terminated prior to December 31, 2025 without the Board of Trustees’ consent. In addition, the manager has agreed to waive the Fund’s management fee to an extent sufficient to offset the net management fee payable in connection with any investment in an affiliated money market fund.

⁵  Excludes securities delivered as a result of a redemption in-kind.

28 ClearBridge Small Cap Growth Fund 2023 Annual Report

Notes to financial statements

1. Organization and significant accounting policies

ClearBridge Small Cap Growth Fund (the “Fund”) is a separate diversified investment series of Legg Mason Partners Investment Trust (the “Trust”). The Trust, a Maryland statutory trust, is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company.

As of October 1, 2013, the Fund is open for purchases and incoming exchanges only by existing Fund shareholders and certain categories of investors, with certain exceptions. For more information, please see the prospectus supplement dated March 1, 2023.

The Fund follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, Financial Services – Investment Companies (“ASC 946”). The following are significant accounting policies consistently followed by the Fund and are in conformity with U.S. generally accepted accounting principles (“GAAP”), including, but not limited to, ASC 946. Estimates and assumptions are required to be made regarding assets, liabilities and changes in net assets resulting from operations when financial statements are prepared. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ. Subsequent events have been evaluated through the date the financial statements were issued.

(a) Investment valuation. Equity securities for which market quotations are available are valued at the last reported sales price or official closing price on the primary market or exchange on which they trade. The valuations for fixed income securities (which may include, but are not limited to, corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and certain derivative instruments are typically the prices supplied by independent third party pricing services, which may use market prices or broker/dealer quotations or a variety of valuation techniques and methodologies. The independent third party pricing services typically use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar securities. Investments in open-end funds are valued at the closing net asset value per share of each fund on the day of valuation. When the Fund holds securities or other assets that are denominated in a foreign currency, the Fund will normally use the currency exchange rates as of 4:00 p.m. (Eastern Time). If independent third party pricing services are unable to supply prices for a portfolio investment, or if the prices supplied are deemed by the manager to be unreliable, the market price may be determined by the manager using quotations from one or more broker/dealers or at the transaction price if the security has recently been purchased and no value has yet been obtained from a pricing service or pricing broker. When reliable prices are not readily available, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the Fund calculates its net asset value, the Fund values these securities as determined in accordance with procedures approved by the Fund’s Board of Trustees.

ClearBridge Small Cap Growth Fund 2023 Annual Report 29

Notes to financial statements (cont’d)

Pursuant to policies adopted by the Board of Trustees, the Fund’s manager has been designated as the valuation designee and is responsible for the oversight of the daily valuation process. The Fund’s manager is assisted by the Global Fund Valuation Committee (the “Valuation Committee”). The Valuation Committee is responsible for making fair value determinations, evaluating the effectiveness of the Fund’s pricing policies, and reporting to the Fund’s manager and the Board of Trustees. When determining the reliability of third party pricing information for investments owned by the Fund, the Valuation Committee, among other things, conducts due diligence reviews of pricing vendors, monitors the daily change in prices and reviews transactions among market participants.

The Valuation Committee will consider pricing methodologies it deems relevant and appropriate when making fair value determinations. Examples of possible methodologies include, but are not limited to, multiple of earnings; discount from market of a similar freely traded security; discounted cash-flow analysis; book value or a multiple thereof; risk premium/yield analysis; yield to maturity; and/or fundamental investment analysis. The Valuation Committee will also consider factors it deems relevant and appropriate in light of the facts and circumstances. Examples of possible factors include, but are not limited to, the type of security; the issuer’s financial statements; the purchase price of the security; the discount from market value of unrestricted securities of the same class at the time of purchase; analysts’ research and observations from financial institutions; information regarding any transactions or offers with respect to the security; the existence of merger proposals or tender offers affecting the security; the price and extent of public trading in similar securities of the issuer or comparable companies; and the existence of a shelf registration for restricted securities.

For each portfolio security that has been fair valued pursuant to the policies adopted by the Board of Trustees, the fair value price is compared against the last available and next available market quotations. The Valuation Committee reviews the results of such back testing monthly and fair valuation occurrences are reported to the Board of Trustees quarterly.

The Fund uses valuation techniques to measure fair value that are consistent with the market approach and/or income approach, depending on the type of security and the particular circumstance. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.

GAAP establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are summarized in the three broad levels listed below:

• Level 1 — unadjusted quoted prices in active markets for identical investments

• Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

• Level 3 — significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used in valuing the Fund’s assets carried at fair value:

† See Schedule of Investments for additional detailed categorizations.

(b) Written options. The Fund may write option contracts generally to gain or reduce exposure to types of investments or market factors or as a means of attempting to enhance returns. When the Fund writes an option, an amount equal to the premium received by the Fund is recorded as a liability, the value of which is marked-to-market daily to reflect the current market value of the option written. If the option expires, the premium received is recorded as a realized gain. When a written call option is exercised, the difference between the premium received plus the option exercise price and the Fund’s basis in the underlying security (in the case of a covered written call option), or the cost to purchase the underlying security (in the case of an uncovered written call option), including brokerage commission, is recognized as a realized gain or loss. When a written put option is exercised, the amount of the premium received is subtracted from the cost of the security purchased by the Fund from the exercise of the written put option to form the Fund’s basis in the underlying security purchased. The writer or buyer of an option traded on an exchange can liquidate the position before the exercise of the option by entering into a closing transaction. The cost of a closing transaction is deducted from the original premium received resulting in a realized gain or loss to the Fund.

The risk in writing a covered call option is that the Fund may forego the opportunity of profit if the market price of the underlying security increases and the option is exercised. The risk in writing a put option is that the Fund may incur a loss if the market price of the underlying security decreases and the option is exercised. The risk in writing an uncovered call option is that the Fund is exposed to the risk of loss if the market price of the underlying security increases. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market.

(c) Foreign investment risks. The Fund’s investments in foreign securities may involve risks not present in domestic investments. Since securities may be denominated in foreign currencies, may require settlement in foreign currencies or may pay interest or dividends in

ClearBridge Small Cap Growth Fund 2023 Annual Report 31

Notes to financial statements (cont’d)

foreign currencies, changes in the relationship of these foreign currencies to the U.S. dollar can significantly affect the value of the investments and earnings of the Fund. Foreign investments may also subject the Fund to foreign government exchange restrictions, expropriation, taxation or other political, social or economic developments, all of which affect the market and/or credit risk of the investments.

(d) Counterparty risk and credit-risk-related contingent features of derivative instruments. The Fund may invest in certain securities or engage in other transactions where the Fund is exposed to counterparty credit risk in addition to broader market risks. The Fund may invest in securities of issuers, which may also be considered counterparties as trading partners in other transactions. This may increase the risk of loss in the event of default or bankruptcy by the counterparty or if the counterparty otherwise fails to meet its contractual obligations. The Fund’s subadviser attempts to mitigate counterparty risk by (i) periodically assessing the creditworthiness of its trading partners, (ii) monitoring and/or limiting the amount of its net exposure to each individual counterparty based on its assessment and (iii) requiring collateral from the counterparty for certain transactions. Market events and changes in overall economic conditions may impact the assessment of such counterparty risk by the subadviser. In addition, declines in the values of underlying collateral received may expose the Fund to increased risk of loss.

With exchange traded and centrally cleared derivatives, there is less counterparty risk to the Fund since the exchange or clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the credit risk is limited to failure of the clearinghouse. While offset rights may exist under applicable law, the Fund does not have a contractual right of offset against a clearing broker or clearinghouse in the event of a default of the clearing broker or clearinghouse.

The Fund has entered into master agreements, such as an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement, with certain of its derivative counterparties that govern over-the-counter (“OTC”) derivatives and provide for general obligations, representations, agreements, collateral posting terms, netting provisions in the event of default or termination and credit related contingent features. The credit related contingent features include, but are not limited to, a percentage decrease in the Fund’s net assets or net asset value per share over a specified period of time. If these credit related contingent features were triggered, the derivatives counterparty could terminate the positions and demand payment or require additional collateral.

Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. However, absent an event of default by the counterparty or a termination of the agreement, the terms of the ISDA Master Agreements do not result in an offset of reported amounts of financial assets and financial liabilities in the Statement of Assets and Liabilities across transactions between the Fund and the applicable counterparty. The enforceability of the right to offset may vary by jurisdiction.

32 ClearBridge Small Cap Growth Fund 2023 Annual Report

Collateral requirements differ by type of derivative. Collateral or margin requirements are set by the broker or exchange clearinghouse for exchange traded derivatives while collateral terms are contract specific for OTC traded derivatives. Cash collateral that has been pledged to cover obligations of the Fund under derivative contracts, if any, will be reported separately in the Statement of Assets and Liabilities. Securities pledged as collateral, if any, for the same purpose are noted in the Schedule of Investments.

As of October 31, 2023, the Fund did not have any open OTC derivative transactions with credit related contingent features in a net liability position.

(e) Security transactions and investment income. Security transactions are accounted for on a trade date basis. Interest income (including interest income from payment-in-kind securities) is recorded on the accrual basis. Amortization of premiums and accretion of discounts on debt securities are recorded to interest income over the lives of the respective securities, except for premiums on certain callable debt securities which are amortized to the earliest call date. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. Foreign dividend income is recorded on the ex-dividend date or as soon as practicable after the Fund determines the existence of a dividend declaration after exercising reasonable due diligence. The cost of investments sold is determined by use of the specific identification method. To the extent any issuer defaults or a credit event occurs that impacts the issuer, the Fund may halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.

(f) Distributions to shareholders. Distributions from net investment income and distributions of net realized gains, if any, are declared at least annually. Distributions to shareholders of the Fund are recorded on the ex-dividend date and are determined in accordance with income tax regulations, which may differ from GAAP.

(g) Share class accounting. Investment income, common expenses and realized/ unrealized gains (losses) on investments are allocated to the various classes of the Fund on the basis of daily net assets of each class. Fees relating to a specific class are charged directly to that share class.

(h) Compensating balance arrangements. The Fund has an arrangement with its custodian bank whereby a portion of the custodian’s fees is paid indirectly by credits earned on the Fund’s cash on deposit with the bank.

(i) Federal and other taxes. It is the Fund’s policy to comply with the federal income and excise tax requirements of the Internal Revenue Code of 1986 (the “Code”), as amended, applicable to regulated investment companies. Accordingly, the Fund intends to distribute its taxable income and net realized gains, if any, to shareholders in accordance with timing requirements imposed by the Code. Therefore, no federal or state income tax provision is required in the Fund’s financial statements.

Management has analyzed the Fund’s tax positions taken on income tax returns for all open tax years and has concluded that as of October 31, 2023, no provision for income tax is required in the Fund’s financial statements. The Fund’s federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

Notes to financial statements (cont’d)

(j) Reclassification. GAAP requires that certain components of net assets be reclassified to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset value per share. During the current year, the following reclassifications have been made:

	Total Distributable Earnings (Loss)		Paid-in Capital
(a)	$	(12,439,706)	$	12,439,706

^(a)  Reclassifications are due to a tax net operating loss and book/tax differences in the treatment of an in-kind distribution of securities.

2. Investment management agreement and other transactions with affiliates

Legg Mason Partners Fund Advisor, LLC (“LMPFA”) (effective November 30, 2023, renamed Franklin Templeton Fund Adviser, LLC) is the Fund’s investment manager and ClearBridge Investments, LLC (“ClearBridge”) is the Fund’s subadviser. Western Asset Management Company, LLC (“Western Asset”) manages the portion of the Fund’s cash and short-term instruments allocated to it. LMPFA, ClearBridge and Western Asset are indirect, wholly-owned subsidiaries of Franklin Resources, Inc. (“Franklin Resources”).

Under the investment management agreement, the Fund pays an investment management fee, calculated daily and paid monthly, at an annual rate of 0.75% of the Fund’s average daily net assets.

LMPFA provides administrative and certain oversight services to the Fund. LMPFA delegates to the subadviser the day-to-day portfolio management of the Fund, except for the management of the portion of the Fund’s cash and short-term instruments allocated to Western Asset. For its services, LMPFA pays ClearBridge a fee monthly, at an annual rate equal to 70% of the net management fee it receives from the Fund. For Western Asset’s services to the Fund, LMPFA pays Western Asset monthly 0.02% of the portion of the Fund’s average daily net assets that are allocated to Western Asset by LMPFA.

As a result of expense limitation arrangements between the Fund and LMPFA, the ratio of total annual fund operating expenses, other than interest, brokerage commissions, taxes, extraordinary expenses and acquired fund fees and expenses, to average net assets of Class A, Class C, Class FI, Class R, Class I and Class IS shares did not exceed 1.28%, 2.09%, 1.35%, 1.60%, 1.00% and 0.90%, respectively. In addition, the ratio of total annual fund operating expenses for Class IS shares did not exceed the ratio of total annual fund operating expenses for Class I shares and the ratio of total annual fund operating expenses for Class 1 shares did not exceed the ratio of total annual fund operating expenses for Class A shares. These expense limitation arrangements cannot be terminated prior to December 31, 2025 without the Board of Trustees’ consent. In addition, the manager has agreed to waive the Fund’s management fee to an extent sufficient to offset the net management fee payable in connection with any investment in an affiliated money market fund (the “affiliated money market fund waiver”). The affiliated money market fund waiver is not subject to the recapture provision discussed below.

34 ClearBridge Small Cap Growth Fund 2023 Annual Report

During the year ended October 31, 2023, fees waived and/or expenses reimbursed amounted to $12,186, all of which was an affiliated money market fund waiver.

LMPFA is permitted to recapture amounts waived and/or reimbursed to a class during the same fiscal year if the class’ total annual fund operating expenses have fallen to a level below the expense limitation (“expense cap”) in effect at the time the fees were earned or the expenses incurred. In no case will LMPFA recapture any amount that would result, on any particular business day of the Fund, in the class’ total annual fund operating expenses exceeding the expense cap or any other lower limit then in effect.

Franklin Distributors, LLC (“Franklin Distributors”) serves as the Fund’s sole and exclusive distributor. Franklin Distributors is an indirect, wholly-owned broker-dealer subsidiary of Franklin Resources. Franklin Templeton Investor Services, LLC (“Investor Services”) serves as the Fund’s shareholder servicing agent and acts as the Fund’s transfer agent and dividend-paying agent. Investor Services is an indirect, wholly-owned subsidiary of Franklin Resources. For the year ended October 31, 2023, the Fund incurred transfer agent fees as reported on the Statement of Operations, of which $38,412 was earned by Investor Services.

There is a maximum initial sales charge of 5.50% for Class A shares. There is a contingent deferred sales charge (“CDSC”) of 1.00% on Class C shares, which applies if redemption occurs within 12 months from purchase payment. In certain cases, Class A shares have a 1.00% CDSC, which applies if redemption occurs within 18 months from purchase payment. This CDSC only applies to those purchases of Class A shares, which, when combined with current holdings of other shares of funds sold by Franklin Distributors, equal or exceed $1,000,000 in the aggregate. These purchases do not incur an initial sales charge.

For the year ended October 31, 2023, sales charges retained by and CDSCs paid to Franklin Distributors and its affiliates, if any, were as follows:

The Fund, together with other U.S. registered and foreign investment funds (collectively, the “Borrowers”) managed by Franklin Resources or its affiliates, is a borrower in a joint syndicated senior unsecured credit facility totaling $2.675 billion (the “Global Credit Facility”). The Global Credit Facility provides a source of funds to the Borrowers for temporary and emergency purposes, including the ability to meet future unanticipated or unusually large redemption requests. Unless renewed, the Global Credit Facility will terminate on February 2, 2024.

Under the terms of the Global Credit Facility, the Fund shall, in addition to interest charged on any borrowings made by the Fund and other costs incurred by the Fund, pay its share of fees and expenses incurred in connection with the implementation and maintenance of the Global Credit Facility, based upon its relative share of the aggregate net assets of all the Borrowers, including an annual commitment fee of 0.15% based upon the unused portion of the Global Credit Facility. These fees are reflected in the Statement of Operations. The Fund did not utilize the Global Credit Facility during the year ended October 31, 2023.

11. Redemptions in-kind

The Fund may make payment for Fund shares redeemed wholly or in part by distributing portfolio securities to shareholders.

Unrealized appreciation (depreciation)(b)		618,412,843
Total distributable earnings (loss) — net	$	613,912,446

^(a)  Other book/tax temporary differences are attributable to the deferral of certain late year losses for tax purposes and book/tax differences in the timing of the deductibility of various expenses.

^(b)  The difference between book-basis and tax-basis unrealized appreciation (depreciation) is attributable to the tax deferral of losses on wash sales and the difference between the book and tax cost basis of certain investments.

13. Recent accounting pronouncement

In June 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2022-03, Fair Value Measurement (Topic 820) – Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. The amendments in the ASU clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, should not be considered in measuring fair value. The ASU is effective for interim and annual reporting periods beginning after December 15, 2023, with the option of early adoption. Management has reviewed the requirements and believes that the adoption of the ASU will not have a material impact on the financial statements.

42 ClearBridge Small Cap Growth Fund 2023 Annual Report

Board approval of management and subadvisory agreements (unaudited)

At an in-person meeting of the Board of Trustees of Legg Mason Partners Investment Trust (the “Trust”) held on May 3-4, 2023, the Board, including the Trustees who are not considered to be “interested persons” of the Trust (the “Independent Trustees”) under the Investment Company Act of 1940, as amended (the “1940 Act”), approved for an annual period the continuation of the management agreement (the “Management Agreement”) between the Trust and Legg Mason Partners Fund Advisor, LLC (the “Manager”) with respect to ClearBridge Small Cap Growth Fund, a series of the Trust (the “Fund”), and the sub-advisory agreement pursuant to which ClearBridge Investments, LLC (“ClearBridge”) provides day-to-day management of the Fund’s portfolio, and the sub-advisory agreement pursuant to which Western Asset Management Company, LLC (“Western Asset” and, together with ClearBridge, the “Sub-Advisers”) provides day-to-day management of the Fund’s cash and short-term instruments allocated to it by the Manager. The management agreement and sub-advisory agreements are collectively referred to as the “Agreements.”

Background

The Board received extensive information in advance of the meeting to assist it in its consideration of the Agreements and asked questions and requested additional information from management. Throughout the year the Board (including its various committees) had met with representatives of the Manager and the Subadvisers, and had received information relevant to the renewal of the Agreements. Prior to the meeting the Independent Trustees met with their independent legal counsel to discuss and consider the information provided and submitted questions to management, and they considered the responses provided. The Board received and considered a variety of information about the Manager and the Subadvisers, as well as the management, advisory and sub-advisory arrangements for the Fund and other funds overseen by the Board, certain portions of which are discussed below. The information received and considered by the Board both in conjunction with the May 2023 meeting and throughout the year was both written and oral. The contractual arrangements discussed below are the product of multiple years of review and negotiation and information received and considered by the Board during those years.

The information provided and presentations made to the Board encompassed the Fund and all funds for which the Board has responsibility. The discussion below covers both the advisory and the administrative functions being rendered by the Manager, both of which functions are encompassed by the Management Agreement, as well as the advisory functions rendered by the Subadvisers pursuant to the Sub-Advisory Agreements.

Board approval of management agreement and sub-advisory agreements

The Independent Trustees were advised by separate independent legal counsel throughout the process. Prior to voting, the Independent Trustees received a memorandum from their independent legal counsel discussing the legal standards for their consideration of the proposed continuation of the Agreements. The Independent Trustees also reviewed the

ClearBridge Small Cap Growth Fund 43

Board approval of management and subadvisory agreements (unaudited) (cont’d)

proposed continuation of the Management Agreement and the Sub-Advisory Agreements in private sessions with their independent legal counsel at which no representatives of the Manager and Subadvisers were present. The Independent Trustees considered the Management Agreement and each Sub-Advisory Agreement separately in the course of their review. In doing so, they noted the respective roles of the Manager and the Subadvisers in providing services to the Fund.

In approving the Agreements, the Board, including the Independent Trustees, considered a variety of factors, including those factors discussed below. No single factor reviewed by the Board was identified by the Board as the principal factor in determining whether to approve the Management Agreement and the Sub-Advisory Agreements. Each Trustee may have attributed different weight to the various factors in evaluating the Management Agreement and each Sub-Advisory Agreement.

After considering all relevant factors and information, the Board, exercising its business judgment, determined that the continuation of the Agreements was in the best interests of the Fund and its shareholders and approved the continuation of each such agreement for another year.

Nature, extent and quality of the services under the management agreement and sub-advisory agreements

The Board received and considered information regarding the nature, extent and quality of services provided to the Fund by the Manager and the Subadvisers under the Management Agreement and the Sub-Advisory Agreements, respectively, during the past year. The Board noted information received at regular meetings throughout the year related to the services rendered by the Manager in its management of the Fund’s affairs and the Manager’s role in coordinating the activities of the Fund’s other service providers. The Board’s evaluation of the services provided by the Manager and the Subadvisers took into account the Board’s knowledge gained as Trustees of funds in the fund complex overseen by the Trustees, including knowledge gained regarding the scope and quality of the investment management and other capabilities of the Manager and the Subadvisers, and the quality of the Manager’s administrative and other services. The Board observed that the scope of services provided by the Manager and the Subadvisers, and of the undertakings required of the Manager and Subadvisers in connection with those services, including maintaining and monitoring their own and the Fund’s compliance programs, liquidity management programs, derivatives risk management programs, cybersecurity programs and valuation-related policies, had expanded over time as a result of regulatory, market and other developments. The Board also noted that on a regular basis it received and reviewed information from the Manager regarding the Fund’s compliance policies and procedures established pursuant to Rule 38a-1 under the 1940 Act. The Board also considered the risks associated with the Fund borne by the Manager and its affiliates (such as entrepreneurial, operational, reputational, litigation and regulatory risk), as well as the Manager’s and each Subadviser’s risk management processes.

The Board reviewed the qualifications, backgrounds and responsibilities of the Manager’s and each Subadviser’s senior personnel and the team of investment professionals primarily responsible for the day-to-day portfolio management of the Fund. The Board also considered, based on its knowledge of the Manager and the Manager’s affiliates, the financial resources of Franklin Resources, Inc., the parent organization of the Manager and the Subadvisers. The Board recognized the importance of having a fund manager with significant resources.

The Board considered the division of responsibilities among the Manager and the Subadvisers and the oversight provided by the Manager. The Board also considered the policies and practices of the Manager and the Subadvisers regarding the selection of brokers and dealers and the execution of portfolio transactions. The Board considered management’s periodic reports to the Board on, among other things, its business plans, any organizational changes and portfolio manager compensation.

The Board received and considered performance information for the Fund as well as for a group of funds (the “Performance Universe”) selected by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent provider of investment company data, based on classifications provided by Thomson Reuters Lipper (“Lipper”). The Board was provided with a description of the methodology used to determine the similarity of the Fund with the funds included in the Performance Universe. It was noted that while the Board found the Broadridge data generally useful, they recognized its limitations, including that the data may vary depending on the end date selected and that the results of the performance comparisons may vary depending on the selection of the peer group and its composition over time. The Board also noted that it had received and discussed with management information throughout the year at periodic intervals comparing the Fund’s performance against its benchmark and against the Fund’s peers. The Board also considered the Fund’s performance in light of overall financial market conditions.

The information comparing the Fund’s performance to that of its Performance Universe, consisting of funds (including the Fund) classified as small-cap growth funds by Lipper, showed, among other data, that the performance of the Fund’s Class I shares for the 1-, 3-, 5- and 10-year periods ended December 31, 2022 was below the median performance of the funds in the Performance Universe for the 1-year period and above the median performance of the funds in the Performance Universe for the 3-, 5- and 10-year periods, and ranked in the first quintile of the funds in the Performance Universe for the 5- and 10-year periods. The Board noted the explanations from the Manager and ClearBridge concerning the reasons for the Fund’s relative performance versus the peer group for the various periods. The Board also noted that the Fund’s performance was ahead of its benchmark for the quarter ended March 31, 2023.

Board approval of management and subadvisory agreements (unaudited) (cont’d)

The Board concluded that, overall, the nature, extent and quality of services provided (and expected to be provided), including performance, under the Management Agreement and each Sub-Advisory Agreement were sufficient for renewal.

Management fees and expense ratios

The Board reviewed and considered the contractual management fee payable by the Fund to the Manager (the “Contractual Management Fee”) and the actual management fees paid by the Fund to the Manager after giving effect to breakpoints and waivers, if any (the “Actual Management Fee”), in light of the nature, extent and quality of the management and sub-advisory services provided by the Manager and the Subadvisers, respectively. The Board also noted that the compensation paid to the Subadvisers is the responsibility and expense of the Manager, not the Fund.

The Board received and considered information provided by Broadridge comparing the Contractual Management Fee and the Actual Management Fee and the Fund’s total actual expenses with those of funds in both the relevant expense group and a broader group of funds, each selected by Broadridge based on classifications provided by Lipper. It was noted that while the Board found the Broadridge data generally useful, they recognized its limitations, including that the data may vary depending on the selection of the peer group. The Board also reviewed information regarding fees charged by the Manager and/or the Subadvisers to other U.S. clients investing primarily in an asset class similar to that of the Fund, including, where applicable, institutional separate and commingled accounts and retail managed accounts.

The Manager reviewed with the Board the differences in services provided to these different types of accounts, noting that the Fund is provided with certain administrative services, office facilities, and Fund officers (including the Fund’s chief executive, chief financial and chief compliance officers), and that the Manager coordinates and oversees the provision of services to the Fund by other Fund service providers. The Board considered the fee comparisons in light of the differences in management of these different types of accounts, and the differences in the degree of entrepreneurial and other risks borne by the Manager in managing the Fund and in managing other types of accounts.

The Board considered the overall management fee, the fees of each of the Subadvisers and the amount of the management fee retained by the Manager after payment of the subadvisory fees, in each case in light of the services rendered for those amounts. The Board also received an analysis of complex-wide management fees provided by the Manager, which, among other things, set out a framework of fees based on asset classes.

46 ClearBridge Small Cap Growth Fund

The Board also received and considered information comparing the Fund’s Contractual Management Fee and Actual Management Fee as well as its actual total expense ratio with those of a group of funds consisting of 19 small-cap growth funds (including the Fund) selected by Broadridge to be comparable to the Fund (the “Expense Group”), and a broader group of funds selected by Broadridge consisting of small-cap growth funds (including the Fund) (the “Expense Universe”). This information showed that the Fund’s Contractual Management Fee was approximately equivalent to the median of management fees payable by the funds in the Expense Group and that the Fund’s Actual Management Fee was below the median of management fees paid by the funds in the Expense Group and at the median of management fees paid by the funds in the Expense Universe. This information also showed that the Fund’s actual total expense ratio was approximately equivalent to the median of the total expense ratios of the funds in the Expense Group and below the median of the actual total expense ratios of the funds in the Expense Universe.

Taking all of the above into consideration, as well as the factors identified below, the Board determined that the management fee and the subadvisory fees for the Fund were reasonable in light of the nature, extent and quality of the services provided to the Fund under the Management Agreement and the Sub-Advisory Agreements.

Manager profitability

The Board received and considered an analysis of the profitability of the Manager and its affiliates in providing services to the Fund. The Board also received profitability information with respect to the Legg Mason Funds complex as a whole. The Board received information with respect to the Manager’s allocation methodologies used in preparing this profitability data. It was noted that the allocation methodologies had previously been reviewed by an outside consultant. The profitability of the Manager and its affiliates was considered by the Board not excessive in light of the nature, extent and quality of the services provided to the Fund.

Economies of scale

The Board received and discussed information concerning whether the Manager realizes economies of scale with respect to the management of the Fund as the Fund’s assets grow.

The Board determined that the management fee structure for the Fund was reasonable.

Other benefits to the manager and the subadvisers

The Board considered other benefits received by the Manager, the Subadvisers and their affiliates as a result of their relationship with the Fund, including the opportunity to offer additional products and services to Fund shareholders, including the appointment of an affiliate of the Manager as the transfer agent of the Fund.

ClearBridge Small Cap Growth Fund 47

Board approval of management and subadvisory agreements (unaudited) (cont’d)

In light of the costs of providing investment management and other services to the Fund and the ongoing commitment of the Manager and the Subadvisers to the Fund, the Board considered that the ancillary benefits that the Manager, the Subadvisers and their affiliates received were reasonable.

48 ClearBridge Small Cap Growth Fund

Statement regarding liquidity risk management program (unaudited)

Each of the Franklin Templeton and Legg Mason Funds has adopted and implemented a written Liquidity Risk Management Program (the “LRMP”) as required by Rule 22e-4 under the Investment Company Act of 1940 (the “Liquidity Rule”). The LRMP is designed to assess and manage each Fund’s liquidity risk, which is defined as the risk that the Fund could not meet requests to redeem shares issued by the Fund without significant dilution of remaining investors’ interests in the Fund. In accordance with the Liquidity Rule, the LRMP includes policies and procedures that provide for: (1) assessment, management, and review (no less frequently than annually) of each Fund’s liquidity risk; (2) classification of each Fund’s portfolio holdings into one of four liquidity categories (Highly Liquid, Moderately Liquid, Less Liquid, and Illiquid); (3) for Funds that do not primarily hold assets that are Highly Liquid, establishing and maintaining a minimum percentage of the Fund’s net assets in Highly Liquid investments (called a “Highly Liquid Investment Minimum” or “HLIM”); and (4) prohibiting the Fund’s acquisition of Illiquid investments that would result in the Fund holding more than 15% of its net assets in Illiquid assets. The LRMP also requires reporting to the Securities and Exchange Commission (“SEC”) (on a non-public basis) and to the Board if the Fund’s holdings of Illiquid assets exceed 15% of the Fund’s net assets. Funds with HLIMs must have procedures for addressing HLIM shortfalls, including reporting to the Board and, with respect to HLIM shortfalls lasting more than seven consecutive calendar days, reporting to the SEC (on a non-public basis).

The Director of Liquidity Risk within the Investment Risk Management Group (the “IRMG”) is the appointed Administrator of the LRMP. The IRMG maintains the Investment Liquidity Committee (the “ILC”) to provide oversight and administration of policies and procedures governing liquidity risk management for Franklin Templeton and Legg Mason products and portfolios. The ILC includes representatives from Franklin Templeton’s Risk, Trading, Global Compliance, Legal, Investment Compliance, Investment Operations, Valuation Committee, Product Management and Global Product Strategy.

In assessing and managing each Fund’s liquidity risk, the ILC considers, as relevant, a variety of factors, including the Fund’s investment strategy and the liquidity of its portfolio investments during both normal and reasonably foreseeable stressed conditions; its short and long-term cash flow projections; and its cash holdings and access to other funding sources including the Funds’ interfund lending facility and line of credit. Classification of the Fund’s portfolio holdings in the four liquidity categories is based on the number of days it is reasonably expected to take to convert the investment to cash (for Highly Liquid and Moderately Liquid holdings) or sell or dispose of the investment (for Less Liquid and Illiquid investments), in current market conditions without significantly changing the investment’s market value.

ClearBridge Small Cap Growth Fund 49

Statement regarding liquidity risk management program (unaudited) (cont’d)

Each Fund primarily holds liquid assets that are defined under the Liquidity Rule as “Highly Liquid Investments,” and therefore is not required to establish an HLIM. Highly Liquid Investments are defined as cash and any investment reasonably expected to be convertible to cash in current market conditions in three business days or less without the conversion to cash significantly changing the market value of the investment.

At meetings of the Funds’ Board of Trustees held in May 2023, the Program Administrator provided a written report to the Board addressing the adequacy and effectiveness of the program for the year ended December 31, 2022. The Program Administrator report concluded that (i.) the LRMP, as adopted and implemented, remains reasonably designed to assess and manage each Fund’s liquidity risk; (ii.) the LRMP, including the Highly Liquid Investment Minimum (“HLIM”) where applicable, was implemented and operated effectively to achieve the goal of assessing and managing each Fund’s liquidity risk; and (iii.) each Fund was able to meet requests for redemption without significant dilution of remaining investors’ interests in the Fund.

(e) Audit Committee’s pre–approval policies and procedures described in paragraph (c) (7) of Rule 2-01 of Regulation S-X.

(1) The Charter for the Audit Committee (the “Committee”) of the Board of each registered investment company (the “Fund”) advised by LMPFA or one of their affiliates (each, an “Adviser”) requires that the Committee shall approve (a) all audit and permissible non-audit services to be provided to the Fund and (b) all permissible non-audit services to be provided by

the Fund’s independent auditors to the Adviser and any Covered Service Providers if the engagement relates directly to the operations and financial reporting of the Fund. The Committee may implement policies and procedures by which such services are approved other than by the full Committee.

The Committee shall not approve non-audit services that the Committee believes may impair the independence of the auditors. As of the date of the approval of this Audit Committee Charter, permissible non-audit services include any professional services (including tax services), that are not prohibited services as described below, provided to the Fund by the independent auditors, other than those provided to the Fund in connection with an audit or a review of the financial statements of the Fund. Permissible non-audit services may not include: (i) bookkeeping or other services related to the accounting records or financial statements of the Fund; (ii) financial information systems design and implementation; (iii) appraisal or valuation services, fairness opinions or contribution-in-kind reports; (iv) actuarial services; (v) internal audit outsourcing services; (vi) management functions or human resources; (vii) broker or dealer, investment adviser or investment banking services; (viii) legal services and expert services unrelated to the audit; and (ix) any other service the Public Company Accounting Oversight Board determines, by regulation, is impermissible.

Pre-approval by the Committee of any permissible non-audit services is not required so long as: (i) the aggregate amount of all such permissible non-audit services provided to the Fund, the Adviser and any service providers controlling, controlled by or under common control with the Adviser that provide ongoing services to the Fund (“Covered Service Providers”) constitutes not more than 5% of the total amount of revenues paid to the independent auditors during the fiscal year in which the permissible non-audit services are provided to (a) the Fund, (b) the Adviser and (c) any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund during the fiscal year in which the services are provided that would have to be approved by the Committee; (ii) the permissible non-audit services were not recognized by the Fund at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Committee and approved by the Committee (or its delegate(s)) prior to the completion of the audit.

(2) None of the services described in paragraphs (b) through (d) of this Item were performed in reliance on paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not applicable.

(g) Non-audit fees billed by the Auditor for services rendered to Legg Mason Partners Investment Trust, LMPFA and any entity controlling, controlled by, or under common control with LMPFA that provides ongoing services to Legg Mason Partners Investment Trust during the reporting period were $785,604 in October 31, 2022 and $799,106 in October 31, 2023.

(h) Yes. Legg Mason Partners Investment Trust’s Audit Committee has considered whether the provision of non-audit services that were rendered to Service Affiliates, which were not pre-approved (not requiring pre-approval), is compatible with maintaining the Accountant’s independence. All services provided by the Auditor to the Legg Mason Partners Investment Trust or to Service Affiliates, which were required to be pre-approved, were pre-approved as required.

(i) Not applicable.
