ClearBridge All Cap Growth ESG ETF

Fund overview

Q. What is the Fund's investment strategy?

A. The ClearBridge All Cap Growth ESG ETF (the "Fund") (prior to July 1, 2021, known as ClearBridge All Cap Growth ETF) seeks to achieve long-term capital appreciation. The Fund seeks to invest in a diversified portfolio of large, medium and small capitalization stocks that have the potential for above-average long-term earnings and/or cash flow growth and meet its financial and environmental, social and governance ("ESG") criteria. Under normal circumstances, the Fund invests at least 80% of its net assets in securities that meet its financial and ESG criteria.

We at ClearBridge Investments, LLC ("ClearBridge"), the Fund's subadviser, use a bottom-up investment process that seeks to find inefficiently priced companies with strong fundamentals, incentive-driven management teams, dominant positions in niche markets and/or goods and services that are in high customer demand. We rely on extensive fundamental research that looks to identify companies with a range of growth opportunities while evaluating the company's business model, financial structure and management acumen. Research is conducted by our portfolio managers with input from the sector analysts of ClearBridge's Fundamental Research Team. The team utilizes proprietary and independent research to identify companies whose projected rapid growth in earnings and cash flow is based on their participation in new products or markets.

The ESG evaluation is integrated into a thorough assessment of investment worthiness based on financial criteria as well as ESG considerations including innovative workplace policies, employee benefits and programs; environmental management system strength, eco-efficiency, and life-cycle analysis; community involvement, strategic philanthropy, and reputation management; and strong corporate governance and independence of the board. The ESG analysis is conducted by the fundamental analyst platform on a sector-specific basis, and a proprietary ESG rating is assigned to each company.

For large company growth stocks, the team seeks companies that exhibit superior balance sheets, exceptional management teams and long-term, consistent operating histories. We seek to complement a core group of large capitalization companies with tactical stocks that reflect themes within the prevailing market environment. When looking at small- and medium-sized company growth stocks, we focus on companies with rapid earnings growth potential, unrecognized values, industry leadership and management teams that have a significant ownership stake. The Fund may invest up to 25% of its net assets (at the time of investment) in the equity securities of foreign issuers, either directly or through depositary receipts. We anticipate using a long-term approach to investing that typically results in low portfolio turnover. However, we may take a more active approach to the portfolio, depending upon market conditions.

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

A. Equities delivered robust performance as easy monetary policy and ambitious fiscal spending to ward off the stubborn COVID-19 pandemic and support an economic recovery helped the S&P 500 Indexi to a gain of 30.00%. Growth stocks also delivered stout returns but trailed their value counterparts with the benchmark Russell 3000 Growth Indexii advancing 27.57% compared to a return of 36.64% for the Russell 3000 Value Indexiii.

Fund overview (cont'd)

The period began with positive developments for COVID-19 vaccines and resolution of the U.S. election, which led to a broadening of market leadership. The mega cap and momentum trades that had lifted markets for the last several years and presented relative headwinds for the Fund showed signs of fatigue, with value stocks outperforming growth stocks in the fourth quarter of 2020 for the first time since 2018. Stocks benefited as Joe Biden won the race for president and looked set to govern with a small majority in Congress. Meanwhile, more fiscal stimulus along with 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. Subsequent U.S. Food and Drug Administration ("FDA") approval and initial distribution of the vaccines in December further bolstered the upswing.

The vaccine-propelled rotation in market leadership continued to gain strength in the first quarter of 2021, with efforts to reflate the economy through fiscal and monetary stimulus providing a bid to attractively priced growth companies. Energy was the best performer in the benchmark as crude oil prices rose 21%, while the Information Technology ("IT") and Consumer Discretionary sectors, prime beneficiaries of the work-from-home and e-commerce boom during the pandemic, underperformed.

Ongoing stimulus and easy monetary policy continued to provide support in the spring and summer of 2021, with strong earnings also having a salutary effect on market returns. Growth stocks began to rebound from oversold levels following better than expected first-quarter earnings reports and continued to rise through August after the Federal Reserve Board (the "Fed")iv signaled its vigilance in monitoring a recent spike in inflation. Fed Chairman Jerome Powell's acknowledgement of the inflation threat and the potential to move up the planned timeline of interest rate increases initially spooked markets. Investors soon became convinced, however, that policymakers won't tolerate runaway inflation and will address the risk progressively rather than wait too long and have to hike rates aggressively.

After the yield curvev flattened in the second quarter, rising signs of inflation and a change of tone from the Fed about plans to scale back its accommodative monetary policy caused yields to rise to the end of the reporting period, pressuring most growth stocks.

The cyclical Energy (+91.89%) sector, which has only a minimal weighting in the Russell 3000 Growth Index, was the strongest performer, lifted by a more than 100% jump in crude oil prices. Among sectors with more meaningful exposures, Communication Services (+46.21%) and IT (+30.07%) also outperformed. The Health Care (+23.87%), Consumer Discretionary (+21.48%) and Industrials (+19.92%) sectors, meanwhile, trailed the benchmark.

ClearBridge All Cap Growth ESG ETF 2021 Annual Report

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

A. We took advantage of the market rotation toward value stocks and cyclicals that we saw to start the period, using the rebound in commodity prices, namely oil and steel, to exit longstanding positions in energy and materials companies, NOV Inc. and Nucor, respectively, as well as financials names, Charles Schwab and American Express. In our efforts to increase the up capture of the portfolio and improve our relative performance during strong market periods, proceeds from these sales were directed into disruptive companies with large addressable markets as well as established growth companies with leading positions in the secular growth areas of digital transformation, including software, e-commerce and digital services. We believe these moves should provide greater balance and growth participation for the Fund going forward.

One such example is DocuSign, the leading provider of electronic agreement services for businesses. DocuSign was a new purchase in the first calendar quarter of 2021 that we have subsequently added to significantly. DocuSign's eSignature offering allows agreements to be transacted digitally and is appealing to both small and large organizations. We have been following the company since it was private. Although the growth of its e-signature business accelerated during COVID-19 lockdowns, DocuSign is targeting additional markets in today's anywhere economy and its strong recent results eased fears that the company was simply a pandemic beneficiary.

Within the broader digital services space, we initiated a position in Netflix where we believe the risk/reward is compelling after the stock traded sideways over the last year due to muted recent subscriber growth resulting from COVID-19-related content production delays. Netflix operates a high-quality subscription business with room for continued growth in a large addressable market. We believe Netflix has a strategic advantage in scaling its business given its large content library and lead versus peers in establishing local content studios and partnerships. The company is also entering the video game market with a focus on mobile games, which could open up new growth opportunities and lower subscriber churn over time. Despite still-heavy content investments, Netflix was free cash flow positive in 2020 and is expected to grow free cash flows in 2022 and beyond. In addition, its progress on margin expansion remains underappreciated.

We have also been looking for multiyear secular trends outside of the IT and Internet sectors to help us maintain a portfolio that can perform well in markets with varied sector or factor leadership. In particular, electrification of the global economy and the transition to electric vehicles (EVs) are areas where we continue to add exposure. We are investing in the brains behind EVs through NXP in the control center, Wolfspeed for power management and Aptiv for safety features. Global rideshare leader Uber will also be a key player in the transition from internal combustion engines to EVs. We extended our exposure to electricity infrastructure critical to power EVs with the purchase of Eaton, a manufacturer of power management products for a variety of end markets.

Fund overview (cont'd)

Given the many uncertainties facing investors in the current environment, we would not be surprised to see continued volatility going forward. Regardless of whether market leadership broadens again from the mega cap growth names, we expect to be opportunistic during market and short-term stock dislocations to continue to seed the portfolio with attractive growth businesses that can thrive regardless of investor flows or general sentiment. As growth becomes scarcer and earnings start to normalize, we are gravitating to companies that can continue to post strong results through the cycle. Active management is essential to take advantage of volatility to create attractive entry points in competitively advantaged businesses in growing end markets and those where we see a multiyear improvement story.

* Total returns are based on changes in NAV or market price, respectively. Returns reflect the deduction of all Fund expenses. Returns do not reflect the deduction of brokerage commissions or taxes that investors pay on distributions or the sale of shares.

† Total return assumes the reinvestment of all distributions at NAV.

‡ Total return assumes the reinvestment of all distributions at market price, which typically is based upon the official closing price of the Fund's shares.

Q. What were the leading contributors to performance?

A. On an absolute basis, the Fund's positions in all ten sectors in which it was invested (out of eleven sectors in total) contributed positively to performance for the period. The greatest contributions to absolute returns came from the Fund's holdings in the IT and Communication Services sectors.

Relative to the benchmark, Russell 3000 Growth Index, stock selection in the Materials and Industrials sectors, an overweight allocation to Communication Services and an underweight allocation to the Consumer Staples sector contributed to returns.

In terms of individual Fund holdings, leading contributors to performance for the period included positions in Amazon.com in the Consumer Discretionary sector, the UnitedHealth Group in the Health Care sector, Microsoft, Seagate Technology and Broadcom in the IT sector as well as Facebook in the Communication Services sector.

Q. What were the leading detractors from performance?

A. Relative to the benchmark index, the Fund's overall stock selection and sector allocation detracted from performance. In particular, stock selection in the Health Care sector was the primary headwind to results. Stock selection in the Consumer Discretionary, Communication Services and IT sectors and the Fund's cash positions also had negative impacts on relative returns.

In terms of individual Fund holdings, leading detractors from performance for the period included positions in Vertex Pharmaceuticals in the Health Care sector, Alibaba in the Consumer Discretionary sector as well as Citrix Systems, Splunk and Fidelity National Information Services in the IT sector.

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

A. Over the course of the reporting period, we established new positions in Atlassian, DocuSign, HubSpot, ASML and Workday in the IT sector, Netflix, Sea Limited and Match Group in the Communication Services sector as well as Lyft and Eaton in Industrials sector. We also closed positions in Freeport McMoRan and Nucor in the Materials sector, Zoetis, Amgen, Alexion Pharmaceuticals and BioMarin Pharmaceutical in the Health Care sector, VMware, Nutanix, Texas Instruments and Nuance Communications in the IT sector, Alibaba in the Consumer Discretionary sector, Charles Schwab and American Express in the Financial sector, Anheuser-Busch InBev and Costco Wholesale in the Consumer Staples sector, and Raytheon Technologies, L3Harris Technologies and C.H. Robinson Worldwide and NOV Inc. in the Energy sector.

Fund overview (cont'd)

RISKS:Equity securities are subject to market and price fluctuations. In addition to investments in large-capitalization companies, investments may be made in speculative and/or small-cap and mid-cap companies which involve a higher degree of risk and volatility than investments in larger, more established companies. The Fund's growth-oriented investment style may increase the risks of investing in the Fund. Growth securities typically are very sensitive to market movements because their market prices tend to reflect future expectations. When it appears, those expectations will not be met, the prices of growth securities typically fall. Growth stocks as a group may be out of favor and underperform the overall equity market while the market concentrates on value stocks. The Fund's environmental, social and governance ("ESG") investment strategy may limit the types and number of investment opportunities available to the Fund and, as a result, may underperform funds that are not subject to such criteria. The Fund's ESG investment strategy may result in the Fund investing in securities or industry sectors that underperform the market as a whole, or forgoing opportunities to invest in securities that might otherwise be advantageous to buy. The Fund may also underperform other funds screened for different ESG standards. In addition, the subadviser may be unsuccessful in creating a portfolio composed of companies that exhibit positive ESG characteristics. Although the Fund will not concentrate its investments in any one industry or industry group, it may, like many growth funds, weight its investments toward certain industries, thus increasing its exposure to factors adversely affecting issuers within those industries. Investments may also be made in depositary receipts and other securities of non-U.S. companies in developed and emerging markets which involve risks in addition to those ordinarily associated with investing in domestic securities, including the potentially negative effects of currency fluctuation, political and economic developments, foreign taxation and differences in auditing and other financial standards. 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. Active management and diversification do not ensure gains or protect against market declines. Distributions are not guaranteed and are subject to change. Please see the Fund's prospectus for a more complete discussion of these and other risks and the Fund's investment strategies.

Portfolio holdings and breakdowns are as of September 30, 2021 and are subject to change and may not be representative of the portfolio manager's current or future investments. The Fund's top ten holdings (as a percentage of net assets) as of September 30, 2021 were: Amazon.com Inc. (7.5%), UnitedHealth Group Inc. (5.6%), Facebook Inc. (5.0%), Microsoft Corp. (4.4%), Broadcom Inc. (3.2%), Twitter Inc. (3.1%), Comcast Corp. (3.0%), Visa Inc. (2.7%), NVIDIA Corp. (2.7%) and salesforce.com Inc. (2.4%). Please refer to pages 14 through 17 for a list and percentage breakdown of the Fund's holdings.

The mention of sector breakdowns is for informational purposes only and should not be construed as a recommendation to purchase or sell any securities. The information provided regarding such sectors is not a sufficient basis upon which to make an investment decision. Investors seeking financial advice regarding the appropriateness of investing in any securities or investment strategies discussed should consult their financial professional. The Fund's top five sector holdings (as a percentage of net assets) as of September 30, 2021 were: Information Technology (42.4%), Communication Services (16.8%), Health Care (15.1%), Consumer Discretionary (13.0%) and Industrials (7.7%).

Fund expenses (unaudited)

Example

As a shareholder of the Fund, you may incur two types of costs: (1) transaction costs, such as brokerage commissions paid on purchases and sales of Fund shares; and (2) ongoing costs, including management 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 funds.

This example is based on an investment of $1,000 invested on April 1, 2021 and held for the six months ended September 30, 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 brokerage commissions paid on purchases and sales of Fund shares. 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.

Investors buy and sell shares of the Fund at market price, not NAV, in the secondary market throughout the trading day. These shares are not individually available for direct purchase from or direct redemption to the Fund. The Fund's per share NAV is the value of one share of the Fund and is calculated by dividing the value of total assets less total liabilities by the number of shares outstanding. The NAV return is based on the NAV of the Fund and effective July 1, 2020, market price returns typically are based upon the official closing price of the ETF's shares. Prior to July 1, 2020, market price returns generally were based upon the mid-point between the bid and ask on the Fund's principal trading market when the Fund's NAV was determined, which was typically 4:00 p.m. Eastern time (U.S.). Market price performance reported for periods prior to July 1, 2020 continue to reflect market prices calculated based upon the mid-point between the bid and ask on the Fund's principal trading market typically as of 4:00 p.m. Eastern time (U.S.). These returns do not represent investors' returns had they traded shares at other times. NAV and market price returns assume that dividends and capital gain distributions have been reinvested in the Fund at NAV and market price, respectively. As with other exchange-traded funds, NAV returns and market price returns may differ because of factors such as the supply and demand for Fund shares and investors' assessment of the underlying value of the Fund's portfolio securities.

Investment returns and principal value of an investment will fluctuate so that an investor's shares, when sold, may be worth more or less than their original cost. NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at NAV. The returns shown do not reflect the deduction of brokerage commissions or taxes that investors would pay on distributions or the sale of shares. Performance figures may reflect fee waivers and/or expense reimbursements. In the absence of fee waivers and/or expense reimbursements, the total return would have been lower.

Hypothetical illustration of $10,000 invested in ClearBridge All Cap Growth ESG ETF on May 3, 2017 (inception date), assuming the reinvestment of all distributions, including returns of capital, if any, at net asset value through September 30, 2021. The hypothetical illustration also assumes a $10,000 investment in the Russell 3000 Growth Index. The Fund's per share NAV is the value of one share of the Fund and is calculated by dividing the value of total assets less total liabilities by the number of shares outstanding. The NAV return is based on the NAV of the Fund. The Russell 3000 Growth Index (the "Index") measures the performance of the broad growth segment of the U.S. equity universe. It includes those Russell 3000 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 not subject to the same management and trading expenses as a fund. An index is a statistical composite that tracks a specified financial market, sector, or rules based investment process. Unlike a fund, an index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by a fund. These expenses negatively impact fund performance. All index performance reflects no deduction for fees, expenses or taxes. Please note that an investor cannot invest directly in an index.

ClearBridge All Cap Growth ESG ETF 2021 Annual Report 21

Notes to financial statements

1. Organization and significant accounting policies

ClearBridge All Cap Growth ESG ETF (prior to July 1, 2021, the Fund was known as ClearBridge All Cap Growth ETF) (the "Fund") is a separate diversified investment series of Legg Mason ETF 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.

The Fund is an actively managed exchange-traded fund ("ETF"). ETFs are funds that trade like other publicly-traded securities. Unlike shares of a mutual fund, which can be bought from and redeemed by the issuing fund by all shareholders at a price based on net asset value ("NAV"), shares of the Fund may be directly purchased from and redeemed by the Fund at NAV solely by certain large institutional investors who have entered into agreements with the Fund's distributor ("Authorized Participants"). Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

Shares of the Fund are listed and traded at market prices on NASDAQ. The market price for the Fund's shares may be different from the Fund's NAV. The Fund issues and redeems shares at NAV only in blocks of a specified number of shares or multiples thereof ("Creation Units"). Only Authorized Participants may purchase or redeem Creation Units directly with the Fund at NAV. Creation Units are created and redeemed principally in-kind (although under some circumstances its shares are created and redeemed partially for cash). Except when aggregated in Creation Units, shares of the Fund are not redeemable securities. Shareholders who are not Authorized Participants may not redeem shares directly from the Fund at NAV.

The Fund seeks to achieve long-term capital appreciation through investing in a diversified portfolio of large, medium and small capitalization stocks that have the potential for above-average long-term earnings and/or cash flow growth.

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,

22 ClearBridge All Cap Growth ESG ETF 2021 Annual Report

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 use the currency exchange rates, generally determined as of 4:00 p.m. (London 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 (formerly 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 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.

ClearBridge All Cap Growth ESG ETF 2021 Annual Report 23

Notes to financial statements (cont'd)

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.

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

Description Quoted Prices
(Level 1)

Total Investments $ 218,617,506 - - $ 218,617,506

See Schedule of Investments for additional detailed categorizations.

(b) 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.

24 ClearBridge All Cap Growth ESG ETF 2021 Annual Report

(c) 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.

(d) 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.

(e) 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.

(f) 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 September 30, 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.

Under the applicable foreign tax laws, a withholding tax may be imposed on interest, dividends and capital gains at various rates.

ClearBridge All Cap Growth ESG ETF 2021 Annual Report 25

Notes to financial statements (cont'd)

(g) 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) $ (10,852,812) $ 10,852,812

Under the investment management agreement and subject to the general supervision of the Fund's Board of Trustees, LMPFA provides or causes to be furnished all investment management, supervisory, administrative and other services reasonably necessary for the operation of the Fund, including certain distribution services (provided pursuant to a separate distribution agreement) and investment advisory services (provided pursuant to separate subadvisory agreements) under a unitary fee structure.

ClearBridge All Cap Growth ESG ETF 2021 Annual Report 27

Notes to financial statements (cont'd)

Fund constitute a Creation Unit. Such transactions are made principally on an in-kind basis and under some circumstances partially on a cash basis, with a separate cash payment, which is a balancing cash component to equate the transaction to the net asset value per share of the Fund on the transaction date. Transactions in capital shares of the Fund are disclosed in detail in the Statement of Changes in Net Assets. Authorized Participants are subject to standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. Creations and redemptions for cash (when cash creations and redemptions are available or specified) may be subject to an additional variable fee.

6. Income tax information and distributions to shareholders

The tax character of distributions paid during the fiscal years ended September 30, was as follows:

2021 2020
Distributions paid from:
Ordinary income $ 960,002 $ 938,004
Net long-term capital gains - 158,742
Total distributions paid $ 960,002 $ 1,096,746

As of September 30, 2021, the components of distributable earnings (loss) on a tax basis were as follows:

Undistributed ordinary income - net $ 921,289
Undistributed long-term capital gains - net 4,877,296
Total undistributed earnings $ 5,798,585
Unrealized appreciation (depreciation)(a) 63,941,827
Total distributable earnings (loss) - net $ 69,740,412
(a)

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

7. 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 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.

8. 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.

9. Subsequent event

In September 2021, the Fund's Board of Trustees approved changing the Fund's fiscal year end from September 30th to March 31st.

Report of independent registered public accounting firm

To the Board of Trustees of Legg Mason ETF Investment Trust and Shareholders of ClearBridge All Cap Growth ESG ETF

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of ClearBridge All Cap Growth ESG ETF (one of the funds constituting Legg Mason ETF Investment Trust, referred to hereafter as the "Fund") as of September 30, 2021, the related statement of operations for the year ended September 30, 2021, the statement of changes in net assets for each of the two years in the period ended September 30, 2021, including the related notes, and the financial highlights for the four years ended September 30, 2021 and the period May 3, 2017 (inception date) through September 30, 2017 (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 September 30, 2021, the results of its operations for the year then ended, the changes in its net assets for each of the two years ended September 30, 2021 and the financial highlights for each of the four years in the period ended September 30, 2021 and for the period May 3, 2017 (inception date) through September 30, 2017 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 September 30, 2021 by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion.

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 ETF Investment Trust, the percentage of fees that were approved by the audit committee, with respect to: Audit-Related Fees were 100% and 100% for September 30, 2020 and September 30, 2021; Tax Fees were 100% and 100% for September 30, 2020 and September 30, 2021; and Other Fees were 100% and 100% for September 30, 2020 and September 30, 2021.
(f) N/A
(g) Non-audit fees billed by the Auditor for services rendered to Legg Mason ETF Investment Trust, LMPFA and any entity controlling, controlled by, or under common control with LMPFA that provides ongoing services to Legg Mason ETF Investment Trust during the reporting period were $707,833 in September 30, 2020 and $643,089 in September 30, 2021.
(h) Yes. Legg Mason ETF 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 ETF Investment Trust or to Service Affiliates, which were required to be pre-approved, were pre-approved as required.
