II ClearBridge All Cap Growth ETF

Fund overview

Q. What is the Fund’s investment strategy?

A. The ClearBridge All Cap Growth ETF (the “Fund”) 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. 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. The bottom-up process that we use relies 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 the 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. For large company growth stocks, the team seeks companies that exhibit superior balance sheets, exceptional management teams and long-term, consistent operating histories. We attempt to complement this core group of 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.

Information showing the number of days the market price of the Fund’s shares was greater than the Fund’s net asset value (“NAV”) and the number of days it was less than the Fund’s NAV (i.e., premium or discount) for various time periods is available by visiting the Fund’s website at www.leggmason.com/etf.

Looking for additional information?

The Fund’s daily NAV is available on-line at www.leggmason.com/etf. The Fund is traded under the symbol “CACG” and its closing market price is available on most financial websites. In a continuing effort to provide information concerning the Fund, shareholders may call 1-877-721-1926 (toll free), Monday through Friday from 8:00 a.m. to 5:30 p.m. Eastern Time, for the Fund’s current NAV, market price and other information.

Thank you for your investment in ClearBridge All Cap Growth ETF. As always, we appreciate that you have chosen us to manage your assets and we remain focused on achieving the Fund’s investment goals.

ClearBridge All Cap Growth ETF 2017 Annual Report 1

Fund overview (cont’d)

Sincerely,

ClearBridge Investments, LLC

October 31, 2017

RISKS: The Fund is newly organized, with a limited history of operations. All investments are subject to risk, including the possible loss of principal. 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. 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 depository 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. 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.

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, 2017 and held for the six months ended September 30, 2017, unless otherwise noted.

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.

Based on actual total return1														Based on hypothetical total return4
Actual Total Return2		Beginning Account Value			Ending Account Value			Annualized Expense Ratio			Expenses Paid During the Period3				Hypothetical Annualized Total Return			Beginning Account Value		Ending Account Value			Annualized Expense Ratio			Expenses Paid During the Period5

¹  For the period May 3, 2017 (inception date) to September 30, 2017.

²  Assumes the reinvestment of all distributions, including returns of capital, if any, at net asset value. Total return is not annualized, as it may not be representative of the total return for the year. 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. Past performance is no guarantee of future results.

³  Expenses (net of fee waivers and/or expense reimbursements) are equal to the Fund’s annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal period (150), then divided by 365.

⁴  For the six months ended September 30, 2017.

⁵  Expenses (net of fee waivers and/or expense reimbursements) are equal to the Fund’s annualized expense ratio multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year (183), then divided by 365.

ClearBridge All Cap Growth ETF 2017 Annual Report 13

Notes to financial statements

1. Organization and significant accounting policies

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 The NASDAQ Stock Market LLC (“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, which may use market prices or broker/dealer quotations or a variety of valuation techniques and methodologies. The independent third party pricing services use inputs that are

14 ClearBridge All Cap Growth ETF 2017 Annual Report

observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar securities. Short-term fixed income securities that will mature in 60 days or less are valued at amortized cost, unless it is determined that using this method would not reflect an investment’s fair value. 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 Legg Mason North Atlantic Fund Valuation Committee (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.

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

ClearBridge All Cap Growth ETF 2017 Annual Report 15

Notes to financial statements (cont’d)

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:

ASSETS
Description	Quoted Prices (Level 1)		Other Significant Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Common stocks†	$	35,706,503		—		—	$	35,706,503
Short-term investments†		909,434		—		—		909,434
Total investments	$	36,615,937		—		—	$	36,615,937

† 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 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.

(c) Security transactions and investment income. Security transactions are accounted for on a trade date basis. Interest income (including interest income from

16 ClearBridge All Cap Growth ETF 2017 Annual Report

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) 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.

(e) 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 and has concluded that as of September 30, 2017, no provision for income tax is required in the Fund’s financial statements.

(f) 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 period ended September 30, 2017, the Fund had no reclassifications.

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 (“Western Asset”) manages the portion of the Fund’s cash and short-term instruments allocated to it. LMPFA, ClearBridge and Western Asset are wholly-owned subsidiaries of Legg Mason, Inc. (“Legg Mason”).

LMPFA provides administrative and certain oversight services to the Fund. LMPFA delegates to the subadviser the day-to-day portfolio management of the Fund. The Fund is responsible for paying interest expenses, taxes, brokerage expenses, future 12b-1 fees (if any), acquired fund fees and expenses, extraordinary expenses and the management fee payable to LMPFA under the investment management agreement. LMPFA has agreed to pay all of the Fund’s organization and offering costs.

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

ClearBridge All Cap Growth ETF 2017 Annual Report 17

Notes to financial statements (cont’d)

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. The Fund pays an investment management fee, calculated daily and paid monthly, at an annual rate of 0.53% of the Fund’s average daily net assets.

As compensation for its subadvisory services, LMPFA pays ClearBridge monthly 70% of the management fee paid by the Fund to LMPFA, net of (i) all fees and expenses incurred by LMPFA under the investment management agreement (including without limitation any subadvisory fee paid to another subadviser to the Fund) and (ii) expense waivers, if any, and reimbursements. LMPFA pays Western Asset monthly a fee of 0.02% of the portion of the Fund’s average daily net assets allocated to Western Asset for the management of cash and other short-term instruments, net of expense waivers, if any, and reimbursements.

Legg Mason Investor Services, LLC, a wholly-owned broker-dealer subsidiary of Legg Mason, serves as the distributor of Creation Units for the Fund on an agency basis.

The Fund’s Board of Trustees has adopted a Rule 12b-1 shareholder services and distribution plan and under that plan, the Fund is authorized to pay service and/or distribution fees calculated at an annual rate of up to 0.25% of its average daily net assets. No service and/or distribution fees are currently paid by the Fund, and there are no current plans to impose these fees.

All officers and one Trustee of the Trust are employees of Legg Mason or its affiliates and do not receive compensation from the Trust.

3. Investments

At September 30, 2017, the aggregate cost of investments and the aggregate gross unrealized appreciation and depreciation of investments for federal income tax purposes were as follows:

	Cost		Gross Unrealized Appreciation		Gross Unrealized Depreciation		Net Unrealized Appreciation
Securities	$	35,315,329	$	2,080,161	$	(779,553)	$	1,300,608

4. Derivative instruments and hedging activities

During the period ended September 30, 2017, the Fund did not invest in derivative instruments.

5. Fund share transactions

At September 30, 2017, the Trust had an unlimited number of shares of beneficial interest authorized with a par value of $0.00001 per share. Fund shares are issued and redeemed by the Fund only in Creation Units or Creation Unit aggregations, where 50,000 shares of the 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 Fund did not make any distributions during the period ended September 30, 2017.

As of September 30, 2017, the components of accumulated earnings (losses) on a tax basis were as follows:

Undistributed ordinary income — net	$	70,172
Deferred capital losses*		(16,891)
Unrealized appreciation (depreciation)(a)		1,300,608
Total accumulated earnings (losses) — net	$	1,353,889

* These capital losses have been deferred in the current year as either short-term or long-term losses. The losses will be deemed to occur on the first day of the next taxable year in the same character as they were originally deferred and will be available to offset future taxable capital gains.

^(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 October 2016, the U.S. Securities and Exchange Commission adopted new rules and amended existing rules (together, the “final rules”) intended to modernize the reporting and disclosure of information by registered investment companies. In part, the final rules amend Regulation S-X and require standardized, enhanced disclosure about derivatives in investment

ClearBridge All Cap Growth ETF 2017 Annual Report 19

Notes to financial statements (cont’d)

company financial statements, as well as other amendments. The compliance date for the amendments to Regulation S-X was August 1, 2017. The Fund has adopted the amendments to Regulation S-X and, upon evaluation, has concluded that the amendments do not materially impact the financial statement amounts; however, as required, additional or enhanced disclosure has been included.

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

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of the ClearBridge All Cap Growth ETF (the “Fund”), a series of Legg Mason ETF Investment Trust, as of September 30, 2017, and the results of its operations, the changes in its net assets and the financial highlights for the period May 3, 2017 (commencement of operations) through September 30, 2017, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit, which included confirmation of securities as of September 30, 2017 by correspondence with the custodian and brokers, provides a reasonable basis for our opinion.

ClearBridge All Cap Growth ETF 2017 Annual Report 21

Board approval of management and subadvisory agreements (unaudited)

At a meeting of the Trust’s Board of Trustees, the Board considered the initial approval for a two-year period of the management agreement pursuant to which Legg Mason Partners Fund Advisor, LLC (the “Manager”) provides the Fund with investment advisory and administrative services, the sub-advisory agreement pursuant to which ClearBridge Investments, LLC (“ClearBridge”) provides day-to-day management of the Fund’s portfolio, and the sub-advisory agreement pursuant to which Western Asset Management Company (“Western Asset” and, together with ClearBridge, the “Sub-Advisers”) provides day-to-day management of the Fund’s cash and short-term instruments allocated to it by the Manager. (The management agreement and sub-advisory agreements are collectively referred to as the “Agreements.”) The Manager and the Sub-Advisers are wholly-owned subsidiaries of Legg Mason, Inc. The Trustees who are not “interested persons” (as defined in the Investment Company Act of 1940, as amended (the “Independent Trustees”)) of the Fund were assisted in their review by Fund counsel and independent legal counsel and met with independent legal counsel in executive sessions separate from representatives of the Manager and the Sub-Advisers. The Independent Trustees requested and received information from the Manager and the Sub-Advisers they deemed reasonably necessary for their review of the Agreements and the services to be provided by the Manager and the Sub-Advisers. Included was information about the Manager, the Sub-Advisers and the Fund’s distributor, as well as the management, sub-advisory and distribution arrangements for the Fund.

In voting to approve the Agreements, the Independent Trustees considered whether the approval of the Agreements would be in the best interests of the Fund and its prospective shareholders, an evaluation based on several factors including those discussed below.

Nature, extent and quality of the services to be provided to the fund under the management agreement and sub-advisory agreements

The Board received and considered information regarding the nature, extent and quality of services to be provided to the Fund by the Manager and the Sub-Advisers under the Management Agreement and Sub-Advisory Agreements, respectively. The Trustees also considered the Manager’s supervisory activities over the Sub-Advisers. In addition, the Independent Trustees received and considered other information regarding the administrative and other services to be rendered to the Fund by the Manager, including services specific to the Fund’s operation as an exchange-traded fund. The Board noted information received at regular meetings throughout the year related to the services rendered by the Manager in its management of other funds in the Legg Mason fund complex, and the Manager’s role in coordinating the activities of the Sub-Advisers and the Fund’s other service providers. The Board’s evaluation of the services to be provided by the Manager and the Sub-Advisers took into account the Board’s knowledge and familiarity gained as Trustees of funds in the Legg Mason fund complex, including the scope and quality of the investment management and other capabilities of the Manager and the Sub-Advisers and the quality of the Manager’s administrative and other services. The Board observed that the scope of services provided by the Manager had expanded over time as a result of regulatory and

22 ClearBridge All Cap Growth ETF

other developments, including maintaining and monitoring its own expanded compliance programs and the compliance program to be implemented for the Fund specific to the Fund’s operation as an exchange-traded fund. The Board reviewed information received from the Manager and the Fund’s Chief Compliance Officer regarding the Fund’s compliance policies and procedures established pursuant to Rule 38a-1 under the Investment Company Act of 1940, as amended.

The Board reviewed the qualifications, backgrounds and responsibilities of the Fund’s senior personnel and the portfolio management team that would be primarily responsible for the day-to-day portfolio management of the Fund. The Trustees then discussed with representatives of management the portfolio management strategy of the Fund’s portfolio managers. The Trustees noted that the Manager and the Sub-Advisers were committed to providing the resources necessary to assist the Fund’s portfolio managers in managing the Fund. The Board also considered, based on its knowledge of the Manager and the Manager’s affiliates, the financial resources available to the Manager’s parent organization, Legg Mason, Inc.

The Board considered the division of responsibilities among the Manager and the Sub-Advisers and the oversight provided by the Manager. The Board also considered the arrangements for communication and processing of orders for creations and redemptions of Fund shares. In addition, management also reported to the Board on, among other things, its business plans regarding exchange-traded funds, recent organizational changes, portfolio manager compensation plan and policy regarding portfolio managers’ ownership of fund shares.

The Board concluded that, overall, it was satisfied with the nature, extent and quality of services expected to be provided under the respective Agreement by the Manager and the Sub-Advisers.

Fund performance

Because the Manager and the Sub-Advisers were newly-appointed, the Trustees could not consider their investment performance in managing the Fund’s portfolio as a factor in evaluating the Agreements during the meeting. The Trustees discussed with representatives of the Manager the investment strategy to be employed by the Manager and the Sub-Advisers in the management of the Fund’s assets. The Trustees noted the reputation and experience of the Manager and the Sub-Advisers, as well as the respective portfolio managers’ experience. The Board determined that these factors also supported a decision to approve the Agreements.

Management fees and expense ratios

The Board reviewed and considered the contractual management fee (the “Contractual Management Fee”) payable by the Fund to the Manager in light of the nature, extent and quality of the management and sub-advisory services expected to be provided by the Manager and the Sub-Advisers, respectively. The Board noted that the Manager, and not

ClearBridge All Cap Growth ETF 23

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

the Fund, pays the sub-advisory fees to the Sub-Advisers and, accordingly, that the retention of the Sub-Advisers would not increase the fees and expenses to be incurred by the Fund. The Board also noted that the Manager will pay all fund expenses, other than the Contractual Management Fee and certain other expenses, and will provide the Fund with regulatory compliance and administrative services, office facilities and Fund officers (including the Fund’s chief financial, chief legal and chief compliance officers), and that the Manager will coordinate and oversee the provision of services to the Fund by other fund service providers, including the Sub-Advisers. Because of the Fund’s “unitary fee” structure, the Board recognized that the Fund’s fees and expenses will vary within a much smaller range and the Manager will bear the risk that Fund expenses may increase over time. On the other hand, the Board noted that it is possible that the Manager could earn a profit on the fees charged under the management agreement and would benefit from any price decreases in third-party services covered by the management agreement.

Management also discussed with the Board the Fund’s proposed distribution arrangements, including how the Fund’s distributor would market the Fund. Additionally, the Board received and considered information comparing the Fund’s Contractual Management Fee with those of a group of active and passive exchange-traded funds, including index-based exchange-traded funds that follow a smart beta strategy (i.e., the index is not strictly capitalization-based) and exchange-traded funds that do not have a “unitary fee” structure such as that for the Fund, which showed that the Fund’s Contractual Management Fee was competitive with the management fees paid by such other funds.

Manager profitability

Because the Manager and the Sub-Advisers were newly-appointed, the Trustees could not consider the profitability of the Manager and its affiliates in providing services to the Fund as a factor in evaluating the Agreements during the meeting.

Economies of scale

The Board discussed any economies of scale or other efficiencies that may result from increases in the Fund’s assets. The Board noted that the Fund’s management agreement did not provide for any breakpoints in the Fund’s Contractual Management Fee to the extent the assets of the Fund increase. The Board noted that should material economies of scale exist in the future, a breakpoint structure for the Fund may be appropriate, and that it would continue to monitor the sharing of economies of scale to determine the appropriateness of adding breakpoints in the future. The Board also noted that there are various ways to share potential economies of scale with Fund shareholders and that it appeared that the benefits of any economies of scale would be appropriately shared with shareholders through increased investment in fund management and administration resources.

Taking all of the above into consideration, the Board determined that the management fee was reasonable in light of the nature, extent and quality of the services expected to be provided to the Fund under the Agreements.

24 ClearBridge All Cap Growth ETF

Other benefits to the manager

The Board considered other benefits expected to be received by the Manager and its affiliates, including the Sub-Advisers, as a result of the Manager’s relationship with the Fund, including the opportunity to offer additional products and services to Fund shareholders. In light of the expected costs of providing investment management and other services to the Fund and the Manager’s commitment to the Fund, the other ancillary benefits that the Manager and its affiliates expect to receive were considered reasonable.

Based on their discussions and considerations, including those described above, the Trustees approved the Management Agreement and the Sub-Advisory Agreements.

No single factor reviewed by the Board was identified by the Board as the principal factor in determining whether to approve the Management Agreement and the Sub-Advisory Agreements.

Change in Independent Registered Public Accounting Firm

On August 14, 2017, KPMG LLP (“KPMG”) resigned, at the request of the Fund, as the independent registered public accounting firm to the Fund. The Audit Committee of the Fund’s Board of Trustees participated in, and approved, the decision to change the independent registered public accounting firm. During the Fund’s interim period from inception May 3, 2017 through August 14, 2017, (i) there were no disagreements with KPMG on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of KPMG, would have caused them to make reference to the subject matter of the disagreements in connection with their report on the Fund’s financial statements for such period, and (ii) there were no “reportable events” of the kind described in Item 304(a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934, as amended.

The Audit Committee of the Fund’s Board of Trustees approved the engagement of PricewaterhouseCoopers LLP (“PwC”) as the Fund’s independent registered public accounting firm for the fiscal year ending September 30, 2017. The selection of PwC does not reflect any disagreements with or dissatisfaction by the Fund or the Board of Trustees with the performance of the Fund’s prior independent registered public accounting firm, KPMG. During the Fund’s interim period from inception May 3, 2017 through August 14, 2017, neither the Fund, nor anyone on its behalf, consulted with PwC on items which: (i) concerned the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Fund’s financial statements; or (ii) concerned the subject of a disagreement (as defined in paragraph (a)(1)(iv) of Item 304 of Regulation S-K) or reportable events (as described in paragraph (a)(1)(v) of said Item 304).

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

a) Audit Fees. The aggregate fees billed in the last fiscal period ending September 30, 2017 (the “Reporting Period”) 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 Period, were $0 in 2017.

b) Audit-Related Fees. The aggregate fees billed in the Reporting Period for assurance and related services by the Auditor that are reasonably related to the performance of the Registrant’s financial statements were $0 in 2017.

(c) Tax Fees. The aggregate fees billed in the Reporting Period for professional services rendered by the Auditor for tax compliance, tax advice and tax planning (“Tax Services”) were $0 in 2017. These services consisted of (i) review or preparation of U.S. federal, state, local and excise tax returns; (ii) U.S. federal, state and local tax planning, advice and assistance regarding statutory, regulatory or administrative developments, and (iii) tax advice regarding tax qualification matters and/or treatment of various financial instruments held or proposed to be acquired or held.

There were no fees billed for tax services by the Auditors to service affiliates during the Reporting Period that required pre-approval by the Audit Committee.

d) All Other Fees. There was no other fee billed in the Reporting Period for products and services provided by the Auditor, other than the services reported in paragraphs (a) through (c) for the Item for the Legg Mason ETF Investment Trust.

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 ETF 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 ETF Investment Trust, the percentage of fees that were approved by the audit committee, with respect to: Audit-Related Fees were 100% for 2017; Tax Fees were 100% for 2017; and Other Fees were 100% for 2017.

(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 $0 in 2016 and $160,000 in 2017.

(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.

CODE OF ETHICS

I. Introduction

A. Individuals Covered by the Code

This Code applies to all employees of Legg Mason & Co., LLC and interested directors of the Proprietary Funds who are not otherwise subject to another code of ethics adopted pursuant to either Rule 17j-1 under the Investment Company Act or Rule 204A-1 under the Investment Advisers Act (“Covered Persons”).

1. Without limiting the generality of the foregoing, this Code covers all employees of Legg Mason & Co., LLC who perform services on behalf of the Proprietary Funds as part of the following regulated entities:

a. Legg Mason Investor Services, LLC (“LMIS”).

b. Legg Mason Partners Fund Advisor, LLC (“LMPFA”).

2. For the avoidance of doubt, each of the Legg Mason Registered Advisers (other than LMPFA) have adopted their own codes of ethics, and employees of the Legg Mason Registered Advisers who are subject to the requirements of those codes of ethics (including any who may be registered representatives of LMIS) are not subject to the requirements of this Code.

B. Standards of Business Conduct

This Code is based on the principle that Legg Mason and its affiliates owe a fiduciary duty to Legg Mason’s clients, and that all Covered Persons must therefore avoid activities, interests and relationships that might (i) present a conflict of interest or the appearance of a conflict of interest, or (ii) otherwise interfere with Legg Mason’s ability to make decisions in the best interests of any of its clients. In particular, Covered Persons must at all times comply with the following standards of business conduct:

1. Compliance with Applicable Law. All Covered Persons must comply with the Federal Securities Laws that apply to the business of Legg Mason.

2. Clients Come First. Covered Persons must scrupulously avoid serving their personal interests ahead of the interests of clients. For example, a Covered Person may not induce or cause a client to take action, or not to take action, for the Covered Person’s personal benefit at the expense of the client’s best interests.

3. Avoid Taking Advantage. Covered Persons may not use their knowledge of the Legg Mason Registered Advisers’ investment activities or client portfolio holdings to profit by the market effect of such activities or to engage in short-term or other abusive trading in Reportable Funds.

4. Avoid Other Inappropriate Relationships or Activities. Covered Persons should avoid relationships or activities that could call into question the Covered Person’s ability to exercise independent judgment in the best interests of Legg Mason’s clients. In particular, Covered Persons should take note of the provisions of the Legg Mason Code of Conduct and the Legg Mason Employee Handbook that pertain to confidentiality, corporate opportunities, gifts and entertainment, insider trading and outside business activities. In addition, Covered Persons who are registered representatives of LMIS should also take note of LMIS’s policies and procedures pertaining to these activities.

1

5. Observe the Spirit of the Code. Doubtful situations should be resolved in favor of Legg Mason’s clients. Technical compliance with the Code’s procedures will not automatically insulate from scrutiny any personal Securities Transactions or other course of conduct that might indicate an abuse of these governing principles.

C. Duty to Report Violations

Covered Persons must promptly report all violations of this Code to the Compliance Department.

D. Fiduciary Duty / Political Contributions

Covered Persons are prohibited from making political contributions for the purpose of obtaining or retaining any Legg Mason Registered Adviser or its affiliates as investment advisers. Covered Persons are specifically prohibited from making political contributions to any person for the purpose of influencing the selection or retention of an investment adviser by a government entity. Covered Persons will be required to certify annually that they have and will comply with this provision.

II. Personal Securities Transactions

A. Prohibited Transactions in Individual Securities

Covered Persons are subject to the following restrictions on their personal trading activities in individual securities:

1. Fraudulent Transactions. In connection with the purchase or sale, directly or indirectly, by a Covered Person of (A) a Reportable Security which, within the most recent fifteen (15) calendar days, (i) is or has been held by a Legg Mason client, or (ii) is being or has been considered by a Legg Mason Registered Adviser for purchase by a client, or (B) an Equivalent Security thereof, Covered Persons are prohibited from:

a. Employing any device, scheme or artifice to defraud Legg Mason’s clients;

b. Making any untrue statement of a material fact or omitting to state a material fact necessary to make the statements made, in light of the circumstances under which they were made, not misleading;

c. Engaging in any act, practice or course of business that operates or would operate as a fraud or deceit on Legg Mason’s clients; or

d. Engaging in any manipulative practice with respect to Legg Mason’s clients.

2. Inside Information. Covered Persons are prohibited from engaging in any transaction in a Security (or Equivalent Security) at a time when the Covered Person is in possession of material non-public information regarding the Security or the issuer of the Security.

3. Market Manipulation. Covered Persons are prohibited from engaging in any transactions in a Security (or Equivalent Security) intended to raise, lower or maintain the price of that Security or to create a false appearance of active trading in that Security.

4. Trading on the Knowledge of Client Transactions. Covered Persons are prohibited from engaging in any transactions in a Security (or an Equivalent Security) on the basis of any information they may be in possession of to the effect that (i) a Legg Mason Registered Adviser is or may be considering an investment in or sale of such Security on behalf of its clients or (ii) has or may have an open order in such Security on behalf of its clients.

2

5. Legg Mason, Inc. Stock. Covered Persons are prohibited from engaging in any transaction in Legg Mason securities that is not in compliance with the “Legg Mason, Inc. Policies and Procedures Regarding Acquisitions and Dispositions of Legg Mason Securities,” as the same may be amended from time to time. A copy of this policy is available on the Legg Mason Legal and Compliance Website.

B. Prohibited Transactions in Reportable Funds

1. Market Timing in Reportable Funds. No Covered Person may use his or her knowledge of the portfolio holdings or investment activities of a Reportable Fund to engage in any short-term or other abusive trading strategy involving such Fund that may conflict with the best interests of the Fund and its shareholders.

2. 60-Day Holding Period for Investments in Proprietary Funds. Subject to the exemptions set forth below, no Covered Person may sell (or exchange out of) shares of a Proprietary Fund in which the Covered Person has a Beneficial Interest if the Covered Person has not held the shares of the same Proprietary Fund for sixty (60) calendar days, including any individual retirement account or 401(k) participant account.

3. Additionally, Proprietary Funds that are sold in the LM 401(k) account are also subject to a 60-day minimum waiting period. No Covered Person may buy (or exchange into) shares of a Proprietary Fund within sixty (60) calendar days of a sell of (or exchange out of) shares of the same Proprietary Fund within the same LM 401(k) account.

The following Securities Transactions involving Proprietary Funds are exempt from the 60-day minimum holding period requirement set forth in this Section II.B.2 and II.B.3:

a. Money Market Funds and Other Short-Term Trading Vehicles. Purchases or redemptions of Proprietary Funds that are money market funds or that hold themselves out as short-term trading vehicles.

b. Managed Accounts. Transactions in Proprietary Funds held in a Managed Account in connection with which the Covered Person has no direct or indirect influence or control over the account, is neither consulted nor advised of the trade before it is executed, and has no knowledge of specific management actions taken by a trustee or investment manager.

c. Systematic Investment. Purchases or redemptions of Proprietary Funds pursuant to an Automatic Investment Plan where a prescribed purchase or sale is made automatically on a regular predetermined basis without affirmative action by the Covered Person or pursuant to a similar arrangement approved by the Compliance Department (for example, automated payroll deduction investments by 401(k) participants or automatic dividend reinvestment).

C. Pre-Approval of Investments in Initial Public Offerings and Private Placements

Covered Persons are prohibited from acquiring a Beneficial Interest in a Reportable Security through an initial public offering (other than a new offering of securities issued by a registered open-end investment company) or Private Placement without the prior written approval of the Compliance Department. Requests for such approval shall be submitted to the Compliance Department through Fidelity National Information Services, Inc. (“FIS”)/PTA using substantially the form of “Request for Approval to Invest in an Initial Public Offering or Private Placement” attached hereto as Appendix A.

3

D. Reporting and Trading Requirements

1. Acknowledgement of Receipt; Initial and Periodic Disclosure of Personal Holdings; Annual Certification.

a. Within ten (10) calendar days of being identified as a Covered Person under this Code, each Covered Person must acknowledge that he or she has received and reviewed a copy of the Code, and has disclosed all Securities holdings in which such Covered Person has a Beneficial Interest..

b. Thereafter, on an annual basis, each Covered Person shall give the same acknowledgements and, in addition, shall certify that he or she has complied with all applicable provisions of the Code.

c. Such acknowledgments and certifications shall be provided through FIS/PTA using substantially the form of the “Acknowledgement of Receipt of Code of Ethics, Personal Holdings Report and Annual Certification” attached hereto as Appendix B.

2. Execution of Personal Securities Transactions.

a. Approved Accounts. Unless one of the following exceptions applies, Covered Persons must execute their personal securities transactions involving any Reportable Securities or Reportable Funds in which they have or acquire a Beneficial Interest through one of the following two types of accounts (“Approved Accounts”):

i. Approved Securities Accounts. Securities accounts (including IRA accounts) with financial intermediaries that have been approved by the Compliance Department (an “Approved Securities Account”); or

ii. Approved Retirement Accounts. Participant accounts in retirement plans approved by the Compliance Department on the grounds that either (i) automated feeds into FIS/PTA have been established, or (ii) sufficient policies and procedures are in place to protect any Reportable Funds that may be in the plan from the types of activities prohibited by Sections A and B above (an “Approved Retirement Account”).1

b. Exceptions. The following types of accounts are exempt from the requirements of section 2.a above, subject to compliance with the conditions set forth below:

i. Mutual Fund-Only and Managed Accounts. Covered Persons may have or acquire a Beneficial Interest in Mutual Fund-Only and Managed Accounts that are not Approved Securities Accounts, provided that the requirement set forth in this Code relating to a Managed Account or Mutual Fund-Only Account, as the case may be, are satisfied. To qualify for this exemption, a Covered Person must deliver to the Compliance Department through FIS/PTA a certification in substantially the form of the “Certificate for Managed Accounts or Mutual Fund-Only Accounts” attached hereto as Appendix D.

ii. Outside Retirement Accounts. Covered Persons may have or acquire a Beneficial Interest in a retirement account other than an Approved Retirement Account (an “Outside Retirement Account”), provided that the Covered Person complies with the certification or reporting requirements set forth in Section 3.c below, and provided further that, for purposes of this Code, an IRA account shall be treated as a securities account and not as a retirement account.

1 A list of the approved financial intermediaries and retirement plans may by found on the Legal and Compliance home page on LMEX.

iii. Dividend Reinvestment Plans. Covered Person may have or acquire a Beneficial Interest in securities held in a dividend reinvestment plan account directly with the issuer of the securities or its transfer agent (a “Dividend Reinvestment Plan”), subject to compliance with the requirements of Section 3.a below.

c. Outside Securities Accounts. Covered Persons that have or acquire a Beneficial Interest in a securities account (including an IRA account) other than an Approved Account, Mutual Fund-Only Account, Managed Account or Outside Retirement Account (an “Outside Securities Account”) must obtain the prior written approval to maintain such account from the Compliance Department.

i. A request for such approval must be submitted to the Compliance Department through FIS/PTA using substantially the form of “Request for Approval for an Outside Securities Account” attached hereto as Appendix C. Such approvals will only be granted in extraordinary circumstances.

ii. If the Compliance Department does not approve such request, the Covered Person must arrange to transfer or convert such account into an Approved Account, Managed Account, Mutual Fund-Only Account or Outside Retirement Account as promptly as practicable.

6. Transaction Reporting Requirements. Covered Persons shall report all Securities Transactions in which they have a Beneficial Interest to the Compliance Department in accordance with the following provisions:

a. Approved Accounts, Managed Accounts, Mutual Fund Only and Dividend Reinvestment Plan Accounts. Covered Persons will not be required to arrange for the delivery of duplicate copies of confirmations or periodic statements for any Approved Accounts, Managed Accounts, Mutual Fund Only Accounts or Dividend Reinvestment Plans in which they have or acquire a Beneficial Interest. However, the existence of all such accounts must be disclosed to the Compliance Department pursuant to either Section II.D.1 above or II.D.4 below. In addition, copies of any statements for any Managed Accounts, Mutual Fund Only Accounts or Dividend Reinvestment Plans must be made available for review at the specific request of the Compliance Department.
