ClearBridge Mid Cap Growth Fund    III 

Fund overview

Q. What is the Fund’s investment strategy?

A. The Fund seeks long-term capital growth. The Fund’s portfolio emphasizes equity securities of medium capitalization companies that we believe have the ability to grow their revenues, earnings or cash flow at above average rates over a multi-year time horizon. In conjunction with research resources at ClearBridge Investments, LLC, the Fund’s subadviser, we take a flexible approach designed to identify companies with superior prospects for capital appreciation. In selecting individual companies for investment, some of the sought-after characteristics include:

• Attractive valuations

• Favorable growth and risk/reward profiles

• Strong free cash flow and balance sheets

We use a concentrated bottom-up approach for the Fund. We focus on individual security selection rather than allow macroeconomic considerations to strongly influence sector weights or individual security selection. We utilize the fundamental research analysts who, using their industry expertise, determine the material ESG (environmental, social and governance) factors facing both individual companies and industry sectors and engage with company management regarding the extent to which they promote best practices of such factors. ESG factors may include, but are not necessarily limited to, environmentally - friendly product initiatives, labor audits of overseas supply chains and strong corporate governance. The choice of ESG factors for any particular company reflects the specific industry.

Under normal circumstances, the Fund invests at least 80% of its net assets, plus borrowings for investment purposes, if any, in equity securities of medium capitalization companies or other investments with similar economic characteristics. The Fund may invest up to 20% of the value of its net assets in equity securities of companies that are not considered to be medium capitalization companies. The Fund normally invests in a relatively small number of stocks selected for their long-term growth potential. The Fund invests in common stocks, but may invest in other types of equity securities. The Fund may invest up to 25% of its net assets in the securities of foreign issuers directly or in the form of depositary receipts representing an interest in those securities. The Fund may invest up to 20% of its net assets in debt securities, including debt securities of foreign issuers.

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

A. Equities delivered robust performance during the twelve-month reporting period ended October 31, 2021, as the approval and subsequent rollout of multiple COVID-19 vaccines combined with accommodative monetary policy and ambitious fiscal spending helped the Russell Midcap Indexⁱ to a gain of 45.40%. The market was led by cyclical¹ stocks benefiting from the economic recovery, as reopened businesses, greater mobility and a

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

ClearBridge Mid Cap Growth Fund 2021 Annual Report 1

Fund overview (cont’d)

healthy consumer encouraged spending and production, and high-growth technology stocks benefiting from strong secular trends as well as a lingering stay-at-home environment. More defensive, non-cyclical² sectors trailed. For the reporting period, mid cap growth stocks as measured by the benchmark Russell MidCap Growth Indexⁱⁱ (+39.43%) trailed mid cap value stocks as measured by the Russell Midcap Value Indexⁱⁱⁱ (+48.60%).

The reporting period began with positive developments for COVID-19 vaccines and resolution of the U.S. election, which led to a broadening of market leadership from the mega cap growth stocks that had soared during the height of pandemic lockdowns. Positive COVID-19 vaccine trial results from Pfizer/BioNTech and Moderna increased optimism about an eventual return to normal economic activity, sparking a rally in cyclical areas of the market. In the fourth quarter of 2020, value stocks, led by energy and financials, outperformed growth stocks for the first time since 2018. Stocks also benefited as Joe Biden won the race for president and looked set to govern with a small majority in Congress.

Aggressive fiscal and monetary policies continued unabated in early 2021, helping support consumer demand that, combined with stop-and-start supply chain recovery as COVID-19 rippled through global regions, raised inflation concerns and led to soaring commodity prices. Despite waves of COVID-19 periodically offering a bid to tech stocks that would benefit from a stay-at-home environment, inflation worries led to a steepening yield curve, weighing on high-multiple growth stocks and supporting cyclicals. Amid easing business restrictions and accommodating fiscal and monetary policies, the U.S. economy picked up steam, with business confidence and new jobs numbers increasing steadily.

Markets wavered in September after the Delta variant of COVID-19 put a pause on recovery plays and higher inflation coincided with signals from the Federal Reserve Board that it would reduce its bond buying as early as November and potentially raise the federal funds rate in late 2022 or 2023. Equities delivered a flattish third quarter of 2021, as already- challenging labor and supply shortages and broad-based inflationary pressures intensified, weighing on industrials and materials companies. Robust third-quarter 2021 corporate earnings, however, suggesting companies have largely been able to absorb inflationary pressures, led to strong gains in October and brought the reporting period to a close on a high note.

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

A. This has been a challenging overall market to navigate as businesses that were highly advantaged by conditions in 2020 (think all things digital) continue to prosper but face “tough comps” and the dreaded “negative second derivative” of growth. The balance in the Fund helped during the year as illustrated by the diversity of contributors including both disruptive growth companies that were last year’s strong performers as well as holdings in more defensive areas of the mid cap market.

²  Non-cyclicals consists of the following industries: consumer products, food/beverage, health care, pharmaceuticals, supermarkets and tobacco.

2 ClearBridge Mid Cap Growth Fund 2021 Annual Report

Supporting our approach of seeking to participate in a broad range of growth opportunities among mid cap companies, we established seventeen new positions during the year that were still in the Fund at the reporting period end. Many of these positions were in software companies that continue to play a key role in digital transformation across the economy. We also added a number of health care companies that play a role in supporting biopharmaceutical drug development or harness technology to enhance health care management.

We seek to promote consistent performance by applying discipline and diligence in managing the construction of the Fund. Earnings results and forward guidance have been strong among many of our holdings. We have been parsing which companies have come through the challenges of 2020 much stronger versus those enjoying a cyclical recovery. We trimmed back several of our big winners from 2020 (ServiceNow, MercadoLibre) and have been vetting growth companies with more reasonable valuations.

The Fund outperformed for the year as our preference for sturdy fundamentals and value-creating management teams provided ballast amid rising speculation in newly public risk assets favored on online message boards. The work our team has done over the last several quarters to maintain a high-quality, diversified portfolio while paying close attention to risk has contributed to this resilience through the regular rotation in leadership we have seen in the mid cap market.

DocuSign, for example, delivered first-quarter results that blew past expectations, quelling fears the e-signature provider was simply a COVID-19 beneficiary that would struggle to beat tougher comparisons. Instead, DocuSign highlighted new cloud-based functionality covering the full lifecycle of agreements that doubles its addressable market. The company has already made the investments to expand from its initial business of streamlining the signing of contracts to offer business intelligence and analytics that can help companies run their operations more efficiently. We expect revenues from this new market will begin to ramp up in 2022.

Performance review

For the twelve months ended October 31, 2021, Class A shares of ClearBridge Mid Cap Growth Fund, excluding sales charges, returned 50.73%. The Fund’s unmanaged benchmark, the Russell Midcap Growth Index, returned 39.43% for the same period. The Lipper Mid-Cap Growth Funds Category Average^iv returned 38.94% over the same time frame.

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, 2021, the gross total annual fund operating expense ratios for Class A, Class C, Class R, Class I and Class IS shares were 1.43%, 2.16%, 1.95%, 1.13% and 1.08%, 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.

As a result of expense limitation arrangements, the ratio of total annual fund operating expenses, other than interest, brokerage, taxes, extraordinary expenses and acquired fund fees and expenses, to average net assets will not exceed 1.20% for Class A shares, 1.95% for Class C shares, 1.45% for Class R shares, 0.85% for Class I shares and 0.75% for Class IS shares. In addition, the ratio of total annual fund operating expenses for Class IS shares will not exceed the ratio of total annual fund operating expenses for Class I shares. These expense limitation arrangements cannot be terminated prior to December 31, 2023 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. This management fee waiver is not subject to the recapture provision discussed below.

4 ClearBridge Mid Cap Growth Fund 2021 Annual Report

The manager 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 the manager 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.

Q. What were the leading contributors to performance?

A. On an absolute basis, the Fund produced positive returns in ten of eleven sectors, in which it was invested during the reporting period, with the greatest contributions to returns coming from the information technology (IT), health care and consumer discretionary sectors.

Relative to the Fund’s benchmark, Russell Midcap Growth Index, overall stock selection and sector allocation were beneficial. In particular, stock selection in the health care, consumer discretionary, IT, industrials and consumer staples sectors as well as an underweight to consumer staples and an overweight to real estate drove relative performance.

In terms of individual stocks, leading contributors to performance for the reporting period included positions in Fortinet, Atlassian, Marvell Technology and Palo Alto Networks in the IT sector and United Rentals in the industrials sector.

Q. What were the leading detractors from performance?

A. Relative to the Fund’s benchmark, stock selection in the real estate sector hurt relative performance.

The leading detractors from performance for the reporting period included holdings in Splunk and Wix.com in the IT sector, Teladoc Health in the health care sector, Lyft in the industrials sector and Zynga in the communication services sector.

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

A. The largest additions to the Fund’s portfolio were HubSpot, Avalara and Five9 in the IT sector as well as Etsy and Petco Health and Wellness in the consumer discretionary sector. The largest positions closed during the period were PPD and BioMarin Pharmaceutical in the health care sector, Arista Networks and Citrix Systems in the IT sector and Progressive in the financials sector.

6 ClearBridge Mid Cap Growth Fund 2021 Annual Report

RISKS: The Fund invests in equity securities, which are subject to market and price fluctuations. Mid-cap stocks involve greater risks and volatility than large-cap stocks. International investments are subject to special risks including currency fluctuations and social, economic and political uncertainties, which could increase volatility. These risks are magnified in emerging markets. Emerging markets countries tend to have economic, political and legal systems that are less developed and are less stable than those of more developed countries. Fixed income securities involve interest rate, credit, inflation and reinvestment risks. As interest rates rise, the value of income securities falls. Derivatives, such as options, can be illiquid, may disproportionately increase losses and have a potentially large impact on Fund performance. The Fund tends to invest in a smaller number of stocks than do many mutual funds. As a result, changes in the value of individual stocks may have a significant impact on your investment. 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, 2021 and held for the six months ended October 31, 2021.

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.

All figures represent past performance and are not a guarantee of future results. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. The returns shown do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. Performance figures may reflect compensating balance arrangements, fee waivers and/or expense reimbursements. In the absence of compensating balance arrangements, fee waivers and/or expense reimbursements, the total return would have been lower.

Fund performance (unaudited) (cont’d)

† Hypothetical illustration of $10,000 invested in Class A and C shares and $1,000,000 invested in Class I shares of ClearBridge Mid Cap Growth Fund on October 31, 2011, assuming the deduction of the maximum initial sales charge of 5.75% at the time of investment for Class A shares and the reinvestment of all distributions, including returns of capital, if any, at net asset value through October 31, 2021. The hypothetical illustration also assumes a $10,000 or $1,000,000 investment, as applicable, in the Russell Midcap Growth Index. The Russell Midcap Growth Index (the “Index”) measures the performance of those Russell Midcap Index companies with higher price-to-book ratios and higher forecasted growth values. (A price-to-book ratio is the price of a stock compared to the difference between a company’s assets and liabilities). 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, C and I shares performance indicated on these charts depending on whether greater or lesser sales charges and fees were incurred by shareholders investing in the other classes.

ClearBridge Mid Cap Growth Fund 2021 Annual Report 27

Notes to financial statements

1. Organization and significant accounting policies

ClearBridge Mid Cap Growth Fund (the “Fund”) is a separate diversified investment series of Legg Mason Partners Investment Trust (prior to September 1, 2021, known as Legg Mason Partners Equity 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.

The following are significant accounting policies consistently followed by the Fund and are in conformity with U.S. generally accepted accounting principles (“GAAP”). 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.

The Board of Trustees is responsible for the valuation process and has delegated the supervision of the daily valuation process to the Global Fund Valuation Committee (known as Legg Mason North Atlantic Fund Valuation Committee prior to March 1, 2021) (the “Valuation Committee”). The Valuation Committee, pursuant to the policies adopted by the Board of Trustees, is responsible for making fair value determinations, evaluating the effectiveness of the Fund’s pricing policies, and reporting to the Board of Trustees. When determining the reliability of third party pricing information for investments owned by the

28 ClearBridge Mid Cap Growth Fund 2021 Annual Report

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 — 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.

ClearBridge Mid Cap Growth Fund 2021 Annual Report 29

Notes to financial statements (cont’d)

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

ASSETS
Description	Quoted Prices (Level 1)		Other Significant Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Common Stocks†	$	193,747,736		—		—	$	193,747,736
Short-Term Investments†		6,946,376		—		—		6,946,376
Total Investments	$	200,694,112		—		—	$	200,694,112

† See Schedule of Investments for additional detailed categorizations.

(b) Purchased options. When the Fund purchases an option, an amount equal to the premium paid by the Fund is recorded as an investment on the Statement of Assets and Liabilities, the value of which is marked-to-market to reflect the current market value of the option purchased. If the purchased option expires, the Fund realizes a loss equal to the amount of premium paid. When an instrument is purchased or sold through the exercise of an option, the related premium paid is added to the basis of the instrument acquired or deducted from the proceeds of the instrument sold. The risk associated with purchasing put and call options is limited to the premium paid.

(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 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

   30  ClearBridge Mid Cap Growth Fund 2021 Annual Report

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.

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, 2021, 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), adjusted for amortization of premium and accretion of discount, is recorded on the accrual basis. 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.

Notes to financial statements (cont’d)

(f) REIT distributions. The character of distributions received from Real Estate Investment Trusts (‘‘REITs’’) held by the Fund is generally comprised of net investment income, capital gains, and return of capital. It is the policy of the Fund to estimate the character of distributions received from underlying REITs based on historical data provided by the REITs. After each calendar year end, REITs report the actual tax character of these distributions. Differences between the estimated and actual amounts reported by the REITs are reflected in the Fund’s records in the year in which they are reported by the REITs by adjusting related investment cost basis, capital gains and income, as necessary.

(g) 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.

(h) 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.

(i) 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.

(j) 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, 2021, 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.

(k) 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)	$	49,809	$	(49,809)

^(a)  Reclassifications are due to a tax net operating loss.

2. Investment management agreement and other transactions with affiliates

Legg Mason Partners Fund Advisor, LLC (“LMPFA”) 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, in accordance with the following breakpoint schedule:

Average Daily Net Assets	Annual Rate
First $1 billion		0.750	%
Next $1 billion		0.700
Next $3 billion		0.650
Next $5 billion		0.600
Over $10 billion		0.550

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, taxes, extraordinary expenses and acquired fund fees and expenses, to average net assets of Class A, Class C, Class R, Class I and Class IS shares did not exceed 1.20%, 1.95%, 1.45%, 0.85% and 0.75%, 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. These expense limitation arrangements cannot be terminated prior to December 31, 2023 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.

During the year ended October 31, 2021, fees waived and/or expenses reimbursed amounted to $269,378, which included an affiliated money market fund waiver of $75.

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.

10. Recent accounting pronouncement

In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2020-04, Reference Rate Reform (Topic 848) – Facilitation of the Effects of Reference Rate Reform on Financial Reporting. In January 2021, the FASB issued ASU No. 2021-01, with further amendments to Topic 848. The amendments in the ASUs provide optional temporary accounting recognition and financial reporting relief from the effect of certain types of contract modifications due to the planned discontinuation of

   38  ClearBridge Mid Cap Growth Fund 2021 Annual Report

the LIBOR and other interbank-offered based reference rates as of the end of 2021 and 2023. The ASUs are effective for certain reference rate-related contract modifications that occur during the period March 12, 2020 through December 31, 2022. Management has reviewed the requirements and believes the adoption of these ASUs will not have a material impact on the financial statements.

11. Other matter

The outbreak of the respiratory illness COVID-19 (commonly referred to as “coronavirus”) has continued to rapidly spread around the world, causing considerable uncertainty for the global economy and financial markets. The ultimate economic fallout from the pandemic, and the long-term impact on economies, markets, industries and individual issuers, are not known. The COVID-19 pandemic could adversely affect the value and liquidity of the Fund’s investments, impair the Fund’s ability to satisfy redemption requests, and negatively impact the Fund’s performance. In addition, the outbreak of COVID-19, and measures taken to mitigate its effects, could result in disruptions to the services provided to the Fund by its service providers.

Shareholders of ClearBridge Mid Cap Growth Fund

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of ClearBridge Mid Cap Growth Fund (one of the funds constituting Legg Mason Partners Investment Trust, referred to hereafter as the “Fund”) as of October 31, 2021, the related statement of operations for the year ended October 31, 2021, the statement of changes in net assets for each of the two years in the period ended October 31, 2021, including the related notes, and the financial highlights for each of the five years in the period ended October 31, 2021 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of October 31, 2021, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended October 31, 2021 and the financial highlights for each of the five years in the period ended October 31, 2021 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of October 31, 2021 by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion.

Statement regarding liquidity risk management program (unaudited)

Each Fund 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.

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

   42  ClearBridge Mid Cap Growth Fund

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/Directors held in November 2021, the Program Administrator provided a written report to the Board addressing the adequacy and effectiveness of the program for the year ended December 31, 2020. 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.

Legg Mason Funds Privacy and Security Notice

Your Privacy and the Security of Your Personal Information is Very Important to the Legg Mason Funds

This Privacy and Security Notice (the “Privacy Notice”) addresses the Legg Mason Funds’ privacy and data protection practices with respect to nonpublic personal information the Funds receive. The Legg Mason Funds include any funds sold by the Funds’ distributor, Franklin Distributors, LLC, as well as Legg Mason-sponsored closed-end funds. The provisions of this Privacy Notice apply to your information both while you are a shareholder and after you are no longer invested with the Funds.

The Type of Nonpublic Personal Information the Funds Collect About You

The Funds collect and maintain nonpublic personal information about you in connection with your shareholder account. Such information may include, but is not limited to:

• Personal information included on applications or other forms;

• Account balances, transactions, and mutual fund holdings and positions;

• Bank account information, legal documents, and identity verification documentation;

• Online account access user IDs, passwords, security challenge question responses; and

• Information received from consumer reporting agencies regarding credit history and creditworthiness (such as the amount of an individual’s total debt, payment history, etc.).

How the Funds Use Nonpublic Personal Information About You

The Funds do not sell or share your nonpublic personal information with third parties or with affiliates for their marketing purposes, or with other financial institutions or affiliates for joint marketing purposes, unless you have authorized the Funds to do so. The Funds do not disclose any nonpublic personal information about you except as may be required to perform transactions or services you have authorized or as permitted or required by law.

The Funds may disclose information about you to:

• Employees, agents, and affiliates on a “need to know” basis to enable the Funds to conduct ordinary business, or to comply with obligations to government regulators;

• Service providers, including the Funds’ affiliates, who assist the Funds as part of the ordinary course of business (such as printing, mailing services, or processing or servicing your account with us) or otherwise perform services on the Funds’ behalf, including companies that may perform statistical analysis, market research and marketing services solely for the Funds;

• Permit access to transfer, whether in the United States or countries outside of the United States to such Funds’ employees, agents and affiliates and service providers as required to enable the Funds to conduct ordinary business, or to comply with obligations to government regulators;

• The Funds’ representatives such as legal counsel, accountants and auditors to enable the Funds to conduct ordinary business, or to comply with obligations to government regulators;

• Fiduciaries or representatives acting on your behalf, such as an IRA custodian or trustee of a grantor trust.

Legg Mason Funds Privacy and Security Notice (cont’d)

Except as otherwise permitted by applicable law, companies acting on the Funds’ behalf, including those outside the United States, are contractually obligated to keep nonpublic personal information the Funds provide to them confidential and to use the information the Funds share only to provide the services the Funds ask them to perform. The Funds may disclose nonpublic personal information about you when necessary to enforce their rights or protect against fraud, or as permitted or required by applicable law, such as in connection with a law enforcement or regulatory request, subpoena, or similar legal process. In the event of a corporate action or in the event a Fund service provider changes, the Funds may be required to disclose your nonpublic personal information to third parties. While it is the Funds’ practice to obtain protections for disclosed information in these types of transactions, the Funds cannot guarantee their privacy policy will remain unchanged.

Keeping You Informed of the Funds’ Privacy and Security Practices

The Funds will notify you annually of their privacy policy as required by federal law. While the Funds reserve the right to modify this policy at any time they will notify you promptly if this privacy policy changes.

The Funds’ Security Practices

The Funds maintain appropriate physical, electronic and procedural safeguards designed to guard your nonpublic personal information. The Funds’ internal data security policies restrict access to your nonpublic personal information to authorized employees, who may use your nonpublic personal information for Fund business purposes only.

Although the Funds strive to protect your nonpublic personal information, they cannot ensure or warrant the security of any information you provide or transmit to them, and you do so at your own risk. In the event of a breach of the confidentiality or security of your nonpublic personal information, the Funds will attempt to notify you as necessary, so you can take appropriate protective steps. If you have consented to the Funds using electronic communications or electronic delivery of statements, they may notify you under such circumstances using the most current email address you have on record with them.

In order for the Funds to provide effective service to you, keeping your account information accurate is very important. If you believe that your account information is incomplete, not accurate or not current, if you have questions about the Funds’ privacy practices, or our use of your nonpublic personal information, write the Funds using the contact information on your account statements, email the Funds by clicking on the Contact Us section of the Funds’ website at www.franklintempleton.com, or contact the Fund at 1-877-721-1926.

dealer, agent, fiduciary, or representative acting by or on behalf of, or for, the account of any other person(s) or household, or a financial advisor, or if you have otherwise provided personal information to us separate from the relationship we have with personal investors, the provisions of this Privacy Policy apply to your personal information (as defined by the CCPA).

• In addition to the provisions of the Legg Mason Funds Security and Privacy Notice, you may have the right to know the categories and specific pieces of personal information we have collected about you.

• You also have the right to request the deletion of the personal information collected or maintained by the Funds.

If you wish to exercise any of the rights you have in respect of your personal information, you should advise the Funds by contacting them as set forth below. The rights noted above are subject to our other legal and regulatory obligations and any exemptions under the CCPA. You may designate an authorized agent to make a rights request on your behalf, subject to the identification process described below. We do not discriminate based on requests for information related to our use of your personal information, and you have the right not to receive discriminatory treatment related to the exercise of your privacy rights.

We may request information from you in order to verify your identity or authority in making such a request. If you have appointed an authorized agent to make a request on your behalf, or you are an authorized agent making such a request (such as a power of attorney or other written permission), this process may include providing a password/passcode, a copy of government issued identification, affidavit or other applicable documentation, i.e. written permission. We may require you to verify your identity directly even when using an authorized agent, unless a power of attorney has been provided. We reserve the right to deny a request submitted by an agent if suitable and appropriate proof is not provided.

For the 12-month period prior to the date of this Privacy Policy, the Legg Mason Funds have not sold any of your personal information; nor do we have any plans to do so in the future.

The aggregate fees billed in the last two fiscal years ending October 31, 2020 and October 31, 2021 (the “Reporting Periods”) for professional services rendered by the Registrant’s principal accountant (the “Auditor”) for the audit of the Registrant’s annual financial statements, or services that are normally provided by the Auditor in connection with the statutory and regulatory filings or engagements for the Reporting Periods, were $325,110 in October 31, 2020 and $325,110 in October 31, 2021.

All Other Fees. There were no other non-audit services rendered by the Auditor to Legg Mason Partners Fund Advisors, LLC (“LMPFA”), and any entity controlling, controlled by or under common control with LMPFA that provided ongoing services to Legg Mason Partners Investment Trust requiring pre-approval by the Audit Committee in the Reporting Period.

(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) For the Legg Mason Partners Investment Trust, the percentage of fees that were approved by the audit committee, with respect to: Audit-Related Fees were 100% and 100% for October 31, 2020 and October 31, 2021; Tax Fees were 100% and 100% for October 31, 2020 and October 31, 2021; and Other Fees were 100% and 100% for October 31, 2020 and October 31, 2021.

(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.
