American Customer Satisfaction ETF

The American Customer Satisfaction ETF

The American Customer Satisfaction ETF (“ACSI” or the “Fund”) seeks to track the performance of the American Customer Satisfaction Investible Index (the “Index”). The underlying strategy behind the Index was altered, beginning August 24, 2020, as detailed below.

The Fund, via its Index, uses an objective, rules-based methodology to measure the performance of U.S.-listed companies whose customers have been surveyed and who have been assigned a customer satisfaction score as part of the Customer Satisfaction Data (collectively, “ACSI Companies”). Construction of the Index begins with over 400 ACSI Companies across 46 industries and 10 economic sectors. The initial universe is then screened to eliminate companies whose stock is not principally listed on a U.S. exchange, whose market capitalization is less than $1 billion, or for which the Customer Satisfaction Data is statistically insignificant. The Index is comprised of ACSI Companies in the 25 industries (as classified by the Customer Satisfaction Data) with the highest customer retention, and the company(ies) with the highest ACSI Score in each such industry will be included in the Index (the “Index Companies”). One to three ACSI Companies from each industry are included in the Index based on the number of ACSI Companies in a given industry. The Index will generally be comprised of 25 to 35 companies at the time of each rebalance of the Index.

The Advisor believes that companies who possess higher satisfaction among their customers have higher cash flows, higher profitability, and higher relative stock appreciation over the long term. The source of this data – The American Customer Satisfaction Index – is recognized as a world leader in the measurement and analysis of customer satisfaction. It is the only national cross-industry measure of customer satisfaction in the United States.

The information presented in this report relates to the twelve-month period ended September 30, 2021 (the “Fiscal Year”).

For the Fiscal Year, ACSI generated a total return of 31.91% (NAV) and 31.82% (Market). This compares to the 32.82% total return of its Index, and the 30.00% total return of the Fund’s benchmark index, the S&P 500 Index, for the same period.

We are pleased with the performance profile since the Index change that went into effect on August 24, 2020. From a sector perspective, Consumer Discretionary, Financials and Communication Services were the leading contributors while Utilities, Health Care and Industrials were positive, but responsible for the least contribution. In general, we were hurt by our “Allocation effect” (our relative sector weights) particularly being over-weight Consumer Staples and under-weight Energy for this period. However, our “Selection Effect” (relative stock picks within those industries) was extremely positive, particularly in Consumer Discretionary and Information Technology.

Reviewing individual stocks, leading contributors included The Charles Schwab Corp., Alphabet, Inc. and Etsy, Inc. – which had the highest customer satisfaction scores in their aggregate industries. Conversely, leading detractors included Nordstrom, Inc., The Clorox Company, and AT&T, Inc.

The Index is an objective, rules-based methodology to measure the performance of (i) ACSI Companies and (ii) U.S. sector-specific exchange-traded funds (“ETFs”) used by the Index to supplement its exposure to sectors for which there are too few ACSI Companies to achieve the target sector weights at the time of each rebalance. The Index is sector-weighted to reflect the overall U.S. large cap market, and security-weighted based on the Customer Satisfaction Data. You cannot invest directly in an index.

The S&P 500 Index is a widely recognized capitalization-weighted Index of 500 common stock prices in U.S. companies.

Cash flow is the total amount of money being transferred into and out of a business, especially as affecting liquidity.

Fund holdings are subject to change. Please see the Schedule of Investments for a full list of Fund Holdings.

(1)Performance shown for periods prior to May 24, 2021 reflect the historical performance of the then-existing shares of the American Customer Satisfaction ETF, a series of ETF Series Solutions (the predecessor to the Fund and for which CSat Investment Advisory, L.P., doing business as Exponential ETFs, the Fund’s index provider, served as investment adviser).

This chart illustrates the performance of a hypothetical $10,000 investment made on October 31, 2016 (commencement of operations), and is not intended to imply any future performance. The returns shown do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. The chart assumes reinvestment of capital gains, dividends, and return of capital, if applicable, for a fund and dividends for an index.

Performance data quoted represents past performance and does not guarantee future results. The investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Current performance of the Fund may be lower or higher than the performance quoted. Performance data current to the most recent month end may be obtained by calling (800) 617-0004. The Fund’s net expense ratio is 0.66% (as of the Fund’s most recently filed Prospectus dated May 21, 2021).

American Customer Satisfaction ETF

NOTES TO FINANCIAL STATEMENTS September 30, 2021

NOTE 1 – ORGANIZATION

The American Customer Satisfaction ETF (the “Fund”) is a diversified series of shares of beneficial interest of Tidal ETF Trust (the “Trust”). The Trust was organized as a Delaware statutory trust on June 4, 2018 and is registered with the Securities and Exchange Commission (the “SEC”) under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company and the offering of the Fund’s shares are registered under the Securities Act of 1933, as amended. The Fund is an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946 “Financial Services—Investment Companies.” The Fund commenced operations on October 31, 2016.

The investment objective of the Fund is to track the performance, before fees and expenses, of the American Customer Satisfaction Investable Index (the “Index”).

The Trust acquired the American Customer Satisfaction ETF (the “Predecessor Fund”), a series of ETF Series Solutions, in a tax-free reorganization on May 24, 2021 (the “Reorganization”). As a series of the Trust, the Fund is a continuation of the Predecessor Fund (See Note 9).

NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently followed by the Fund. These policies are in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

A.Security Valuation. Equity securities listed on a securities exchange, market or automated quotation system for which quotations are readily available (except for securities traded on the NASDAQ Stock Market, LLC (“NASDAQ”)), including securities traded over the counter, are valued at the last quoted sale price on the primary exchange or market (foreign or domestic) on which they are traded on the valuation date (or at approximately 4:00 p.m. EST if a security’s primary exchange is normally open at that time), or, if there is no such reported sale on the valuation date, at the most recent quoted bid price or mean between the most recent quoted bid and ask prices for long and short positions. For a security that trades on multiple exchanges, the primary exchange will generally be considered the exchange on which the security is generally most actively traded. For securities traded on NASDAQ, the NASDAQ Official Closing Price will be used. Prices of securities traded on the securities exchange will be obtained from recognized independent pricing agents (“Independent Pricing Agents”) each day that the Fund is open for business.

For securities for which quotations are not readily available, a fair value will be determined by the Valuation Committee using the Fair Value Procedures approved by the Trust’s Board of Trustees (the “Board”). When a security is “fair valued,” consideration is given to the facts and circumstances relevant to the particular situation, including a review of various factors set forth in the Fair Value Procedures adopted by the Board. Fair value pricing is an inherently subjective process, and no single standard exists for determining fair value. Different funds could reasonably arrive at different values for the same security. The use of fair value pricing by a fund may cause the net asset value of its shares to differ significantly from the net asset value that would be calculated without regard to such considerations.

As described above, the Fund utilizes various methods to measure the fair value of its investments on a recurring basis. U.S. GAAP establishes a hierarchy that prioritizes inputs to valuation methods. The three levels of inputs are:

Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities that the Fund has the ability to access.

Level 2 – Observable inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These inputs may include quoted prices for the identical instrument on an inactive market, prices for similar instruments, interest rates, prepayment speeds, credit risk, yield curves, default rates and similar data.

Level 3 – Unobservable inputs for the asset or liability, to the extent relevant observable inputs are not available; representing the Fund’s own assumptions about the assumptions a market participant would use in valuing the asset or liability and would be based on the best information available.

American Customer Satisfaction ETF

NOTES TO FINANCIAL STATEMENTS September 30, 2021 (Continued)

The availability of observable inputs can vary from security to security and is affected by a wide variety of factors, including, for example, the type of security, whether the security is new and not yet established in the marketplace, the liquidity of markets, and other characteristics particular to the security. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3.

The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement falls in its entirety, is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

The following is a summary of the inputs used to value the Fund’s investments as of September 30, 2021:


Investments in Securities	Level 1	Level 2	Level 3	Total
Common Stocks⁽¹⁾	$78,181,071	$—	$—	$78,181,071
Short-Term Investments	143,304	—	—	143,304
Total Investments in Securities	$78,324,375	$—	$—	$78,324,375

⁽¹⁾See Schedule of Investments for the industry breakout.

B.Federal Income Taxes. The Fund has elected to be taxed as a “regulated investment company” and intends to distribute substantially all taxable income to its shareholders and otherwise comply with the provisions of the Internal Revenue Code applicable to regulated investment companies. Therefore, no provision for federal income taxes or excise taxes has been made.

In order to avoid imposition of the excise tax applicable to regulated investment companies, the Fund intends to declare as dividends in each calendar year at least 98.0% of its net investment income (earned during the calendar year) and at least 98.2% of its net realized capital gains (earned during the twelve months ended October 31) plus undistributed amounts, if any, from prior years.

As of September 30, 2021, the Fund did not have any tax positions that did not meet the threshold of being sustained by the applicable tax authority. Generally, tax authorities can examine all the tax returns filed for the last three years. The Fund identifies its major tax jurisdiction as U.S. Federal and the Commonwealth of Delaware; however, the Fund is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially.

C.Securities Transactions and Investment Income. Investment securities transactions are accounted for on the trade date. Gains and losses realized on sales of securities are determined on a specific identification basis. Discounts/premiums on debt securities purchased are accreted/amortized over the life of the respective securities using the effective interest method. Dividend income is recorded on the ex-dividend date. Debt income is recorded on an accrual basis. Other non-cash dividends are recognized as investment income at the fair value of the property received. Withholding taxes on foreign dividends have been provided for in accordance with the Trust’s understanding of the applicable country’s tax rules and rates.

D.Distributions to Shareholders. Distributions to shareholders from net investment income, if any, for the Fund are declared and paid annually. Distributions to shareholders from net realized gains on securities, if any, for the Fund normally are declared and paid on an annual basis. Distributions are recorded on the ex-dividend date.

E.Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amount of revenue and expenses during the reporting period. Actual results could differ from those estimates.

F.Share Valuation. The NAV per share of the Fund is calculated by dividing the sum of the value of the securities held by the Fund, plus cash or other assets, minus all liabilities by the total number of shares outstanding for the Fund, rounded to the nearest cent. The Fund’s shares will not be priced on the days on which the New York Stock Exchange (“NYSE”) is closed for trading.

G.Guarantees and Indemnifications. In the normal course of business, the Fund enters into contracts with service providers that contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, based on experience, the Fund expects the risk of loss to be remote.

American Customer Satisfaction ETF

NOTES TO FINANCIAL STATEMENTS September 30, 2021 (Continued)

H.Illiquid Securities. Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a Board-approved Liquidity Risk Management Program (the “Program”) that requires, among other things, that the Fund limit its illiquid investments that are assets to no more than 15% of the value of the Fund’s net assets. An illiquid investment is any security that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. If the Fund should be in a position where the value of illiquid investments held by the Fund exceeds 15% of the Fund’s net assets, the Fund will take such steps as set forth in the Program.

I.Reclassification of Capital Accounts. U.S. GAAP requires that certain components of net assets relating to permanent differences be reclassified between financial and tax reporting. These reclassifications have no effect on net assets or net asset value per share. These differences are primarily due to adjustments for redemptions in-kind. For the year ended September 30, 2021, the following adjustments were made:


Paid-In Capital		Total Distributed (Accumulated) Earnings (Losses)
$16,788,789		$(16,788,789)

During the year ended September 30, 2021, the Fund realized $17,607,305 in net capital gains resulting from in-kind redemptions, in which shareholders exchanged Fund shares for securities held by the Fund rather than for cash. Because such gains are not taxable to the Fund, and are not distributed to shareholders, they have been reclassified from accumulated earnings to paid-in capital.

NOTE 3 – PRINCIPAL INVESTMENT RISKS

A.Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. For example, the global pandemic caused by COVID-19, a novel coronavirus, and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. The COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.

B.ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:

•Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem shares directly from the Fund (know as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

•Costs of Buying or Selling Shares. Due to the costs of buying or selling shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of shares may significantly reduce investment results and an investment in shares may not be advisable for investors who anticipate regularly making small investments.

•Shares May Trade at Prices Other Than NAV. As with all ETFs, shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of shares will approximate the Fund’s NAV, there may be times when the market price of shares is more than the NAV intra-day (premium) or less than the NAV intra-day

American Customer Satisfaction ETF

NOTES TO FINANCIAL STATEMENTS September 30, 2021 (Continued)

(discount) due to supply and demand of shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant.

•Trading. Although shares are listed for trading on Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares.

C.Models and Data Risk. The composition of the Index is heavily dependent on proprietary quantitative models as well as information and data supplied by third parties (“Models and Data”). When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon may lead to securities being included in or excluded from the Index that would have been excluded or included had the Models and Data been correct and complete. If the composition of the Index reflects such errors, the Fund’s portfolio can be expected to reflect the errors, too.

D.Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.

•Consumer Discretionary Sector Risk. The Fund is generally expected to invest significantly in companies in the consumer discretionary sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability. As of September 30, 2021, 28.5% of the Fund’s net assets were invested in the consumer discretionary sector.

•Consumer Staples Sector Risk. The Fund may invest in companies in the consumer staples sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Companies in the consumer staples sector, including those in the food and beverage industries, may be affected by general economic conditions, commodity production and pricing, consumer confidence and spending, consumer preferences, interest rates, product cycles, marketing campaigns, competition, and government regulations.

•Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

NOTE 4 – COMMITMENTS AND OTHER RELATED PARTY TRANSACTIONS

Toroso Investments, LLC (the “Adviser”) serves as investment adviser to the Fund pursuant to an investment advisory agreement between the Adviser and the Trust, on behalf of the Fund (the “Advisory Agreement”), and, pursuant to the Advisory Agreement, has overall responsibility for the general management and administration of the Fund, subject to the direction and control of the Board. The Adviser is also responsible for trading portfolio securities on behalf of the Fund, including selecting broker-dealers to execute purchase and sales transactions, subject to the supervision of the Board. Prior to the Reorganization, CSat Investment Advisory, L.P., doing business as Exponential ETFs, served as investment advisor to the Predecessor Fund.

Pursuant to the Advisory Agreement, the Fund pays the Adviser a unitary management fee (the “Management Fee”) based on the average daily net assets of the Fund at the annualized rate of 0.65%. Out of the Management Fee, the Adviser is obligated to pay or arrange for the payment of substantially all expenses of the Fund, including the cost of transfer agency, custody, fund administration, and all other related services necessary for the Fund to operate. Under the Advisory Agreement, the Adviser has agreed to pay all expenses incurred

NOTES TO FINANCIAL STATEMENTS September 30, 2021 (Continued)

by the Fund except for interest charges on any borrowings, dividends and other expenses on securities sold short, taxes, brokerage commissions and other expenses incurred in placing orders for the purchase and sale of securities and other investment instruments, acquired fund fees and expenses, accrued deferred tax liability, extraordinary expenses, distribution fees, and expenses paid by the Fund under any distribution plan adopted pursuant to Rule 12b-1 under the 1940 Act (the “Excluded Expenses”), and the Management Fee payable to the Adviser. The Management Fees incurred are paid monthly to the Adviser. The Adviser has entered into an agreement with Exponential ETFs, under which Exponential ETFs assumes the obligation of the Adviser to pay all expenses of the Fund, except Excluded Expenses (such expenses of the Fund, except Excluded Expenses, the “Unitary Expenses”). Although Exponential ETFs has agreed to be responsible for the Unitary Expenses, the Adviser retains the ultimate obligation to the Fund to pay such expenses. Exponential ETFs will also provide marketing support for the Fund, including hosting the Fund’s website and preparing marketing materials related to the Fund. For these services and payments, Exponential ETFs is entitled to a fee, to be paid by the Adviser, based on the total management fee earned by the Adviser under the Advisory Agreement less the Unitary Expenses. Exponential ETFs does not make investment decisions, provide investment advice, or otherwise act in the capacity of an investment adviser to the Fund.

Tidal ETF Services LLC (“Tidal”), an affiliate of the Adviser, serves as the Fund’s administrator and, in that capacity, performs various administrative and management services for the Fund. Tidal coordinates the payment of Fund-related expenses and manages the Trust’s relationships with its various service providers. Prior to the Reorganization, U.S. Bancorp Fund Services, LLC, doing business as U.S. Bank Global Fund Services (“Fund Services”), served as the administrator to the Predecessor Fund.

Fund Services serves as the Fund’s sub-administrator, fund accountant and transfer agent. In those capacities Fund Services performs various administrative and accounting services for the Fund. Fund Services prepares various federal and state regulatory filings, reports and returns for the Fund, including regulatory compliance monitoring and financial reporting; prepares reports and materials to be supplied to the Board; and monitors the activities of the Fund’s custodian. U.S. Bank N.A. (the “Custodian”), an affiliate of Fund Services, serves as the Fund’s custodian.

Foreside Fund Services, LLC (the “Distributor”) acts as the Fund’s principal underwriter in a continuous public offering of the Fund’s shares.

Certain officers and a trustee of the Trust are affiliated with the Adviser and Fund Services. Neither the affiliated trustee nor the Trust’s officers receive compensation from the Fund.

NOTE 5 – PURCHASES AND SALES OF SECURITIES

For the year ended September 30, 2021, the cost of purchases and proceeds from the sales or maturities of securities, excluding short-term investments, U.S. government securities, and in-kind transactions were $36,148,366 and $36,616,104, respectively.

For the year ended September 30, 2021, there were no purchases or sales of long term U.S. Government securities.

For the year ended September 30, 2021, in-kind transactions associated with creations and redemptions for the Fund were $64,017,136 and $62,531,268, respectively.

NOTE 6 – INCOME TAXES AND DISTRIBUTIONS TO SHAREHOLDERS

The tax character of distributions paid during the year ended September 30, 2021 and September 30, 2020, are as follows:


Distributions paid from:	September 30, 2021	September 30, 2020
Ordinary income	$554,952	$991,046

American Customer Satisfaction ETF

NOTES TO FINANCIAL STATEMENTS September 30, 2021 (Continued)

As of the year ended September 30, 2021, the components of accumulated earnings/(losses) on a tax basis were as follows:


	September 30, 2021
Cost of investments⁽¹⁾	$73,905,148
Gross tax unrealized appreciation	$8,124,628
Gross tax unrealized depreciation	(3,705,401	)
Net tax unrealized appreciation (depreciation)	4,419,227
Undistributed ordinary income (loss)	234,683
Undistributed long-term capital gain (loss)	—
Total distributable earnings	234,683
Other accumulated gain (loss)	(8,581,966	)
Total accumulated gain (loss)	$(3,928,056	)

⁽¹⁾The difference between book and tax-basis cost of investments was attributable primarily to the treatment of wash sales.

Net capital losses incurred after October 31 and net investment losses incurred after December 31, and within the taxable year, are deemed to arise on the first business day of the Fund’s next taxable year. As of September 30, 2021, the Fund had no late year losses and had short-term and long-term capital loss carryovers of $5,113,979 and $3,467,987, respectively, which do not expire.

NOTE 7 – SHARE TRANSACTIONS

Shares of the Fund are listed and traded on the Exchange. Market prices for the shares may be different from their NAV. The Fund issues and redeems shares on a continuous basis at NAV generally in large blocks of shares, called (“Creation Units”). Creation Units are issued and redeemed principally in-kind for securities included in a specified universe. Once created, shares generally trade in the secondary market at market prices that change throughout the day. Except when aggregated in Creation Units, shares are not redeemable securities of the Fund. Creation Units may only be purchased or redeemed by Authorized Participants. An Authorized Participant is either (i) a broker-dealer or other participant in the clearing process through the Continuous Net Settlement System of the National Securities Clearing Corporation or (ii) a Depository Trust Company participant and, in each case, must have executed a Participant Agreement with the Distributor. Most retail investors do not qualify as Authorized Participants nor have the resources to buy and sell whole Creation Units. Therefore, they are unable to purchase or redeem the shares directly from the Fund. Rather, most retail investors may purchase shares in the secondary market with the assistance of a broker and are subject to customary brokerage commissions or fees.

The Fund currently offers one class of shares, which has no front-end sales load, no deferred sales charge, and no redemption fee. A fixed transaction fee is imposed for the transfer and other transaction costs associated with the purchase or sale of Creation Units. The standard fixed transaction fee for the Fund is $250, payable to the Custodian. The fixed transaction fee may be waived on certain orders if the Fund’s Custodian has determined to waive some or all of the costs associated with the order or another party, such as the Adviser, has agreed to pay such fee. In addition, a variable fee may be charged on all cash transactions or substitutes for Creation Unit of up to a maximum of 2% and for Redemption Units of up to a maximum of 2%, respectively, of the value of the Creation Units and Redemption Units subject to the transaction. Variable fees received by the Fund, if any, are disclosed in the capital shares transactions section of the Statements of Changes in Net Assets. The Fund may issue an unlimited number of shares of beneficial interest, with no par value. All shares of the Fund have equal rights and privileges.

NOTE 8 – COVID-19 PANDEMIC

U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors including the impact of the novel coronavirus (COVID-19) as a global pandemic, which has resulted in public health issues, growth concerns in the U.S. and overseas, layoffs, rising unemployment claims, changed travel and social behaviors, and reduced consumer spending. The recovery from the effects of COVID-19 is uncertain and may last for an extended period of time. These developments as well as other events could result in further market volatility and negatively affect financial asset prices, the liquidity of certain securities and the normal operations of securities exchanges and other markets. As a result, the risk environment remains elevated. The Adviser will monitor developments and seek to manage the Fund in a manner consistent with the Fund’s investment objective but there can be no assurance that it will be successful in doing so.

NOTE 9 – AGREEMENT AND PLAN OF REORGANIZATION

On May 20, 2021, shareholders of the Predecessor Fund approved an Agreement and Plan of Reorganization between the Trust, on behalf of the Fund, and ETF Series Solutions (“ESS”), a Delaware statutory trust, on behalf of the Predecessor Fund. The Agreement and Plan of Reorganization provided for the transfer of all of the assets of the Predecessor Fund to the Fund and the assumption of the liabilities (other than any excluded liabilities) of the Predecessor Fund by the Fund. For financial reporting purposes, assets received and shares issued by the Fund were recorded at fair value; however, the cost basis of the investments received from the Predecessor Fund was carried forward to align ongoing reporting of the Fund’s realized and unrealized gains and losses with amounts distributable to shareholders for tax purposes. The Fund was created to carry out the reorganization and has an identical investment objective and materially identical principal investment strategies as the Predecessor Fund. The reorganization was effective before the start of business on May 24, 2021. The following table illustrates the specifics of the reorganization of the Predecessor Fund into the Fund:


Predecessor Fund Net Assets	Shares Issued to Shareholders of Predecessor Fund	Fund Net Assets	Combined Net Assets⁽³⁾	Tax Status of Transfer
$76,769,627	1,575,000	$ —	$76,769,627	Non-taxable

⁽³⁾Includes accumulated net investment income, accumulated realized losses and unrealized appreciation in the amounts of $(53,148), $25,868,775, and $6,677,215, respectively.

NOTE 10 – MATTERS SUBMITTED TO A SHAREHOLDER VOTE (Unaudited)

A special meeting of shareholders of the Predecessor Fund was held on May 20, 2021, and the following matter was approved:

American Customer Satisfaction ETF

EXPENSE EXAMPLE For the Six Months Ended September 30, 2021 (Unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including brokerage commissions paid on purchases and sales of the Fund’s shares, and (2) ongoing costs, including management fees of the Fund. The 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. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period indicated, which is from April 1, 2021 to September 30, 2021.

Actual Expenses

The first line of the following table provides information about actual account values and actual expenses. To the extent the Fund invests in shares of other investment companies as part of its investment strategy, you will indirectly bear your proportionate share of any fees and expenses charged by the underlying funds in which the Fund invests, in addition to the expenses of the Fund. Actual expenses of the underlying funds are expected to vary among the various underlying funds. These expenses are not included in the example. The example includes, but is not limited to, unitary fees. However, the example does not include portfolio trading commissions and related expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then, multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Period’’ to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the following table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% 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 this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table 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 the Fund’s shares. Therefore, the second line of the following table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. If these transactional costs were included, your costs would have been higher.


	Beginning Account Value April 1, 2021	Ending Account Value September 30, 2021	Expenses Paid During the Period April 1, 2021 – September 30, 2021⁽¹⁾
Actual	$1,000.00	$1,059.60	$3.36
Hypothetical (5% annual return before expenses)	$1,000.00	$1,021.81	$3.29

⁽¹⁾Expenses are equal to the Fund’s annualized net expense ratio for the most recent six-month period of 0.65%, multiplied by the average account value over the period, multiplied by 183/365 (to reflect the most recent six-month period).

American Customer Satisfaction ETF

STATEMENT REGARDING LIQUIDITY RISK MANAGEMENT PROGRAM (Unaudited)

In accordance with Rule 22e-4 under the Investment Company Act of 1940, as amended (“Rule 22e-4”), Tidal ETF Trust (the “Trust”), on behalf of its series, the American Customer Satisfaction ETF, has adopted and implemented a liquidity risk management program (the “Program”). The Program seeks to promote effective liquidity risk management for the Fund and to protect the Fund’s shareholders from dilution of their interests. The Trust’s Board of Trustees (the “Board”) has approved the designation of Toroso Investments, LLC, the Fund’s investment adviser, as the program administrator (the “Program Administrator”). The Program Administrator has further delegated administration of the Program to a Program Administrator Committee composed of certain Trust officers. The Program Administrator is required to provide a written annual report to the Board regarding the adequacy and effectiveness of the Program, including the operation of the highly liquid investment minimum, if applicable, and any material changes to the Program.

On November 19, 2020, the Board reviewed the Program Administrator’s written annual report for the period December 1, 2019 through September 30, 2020 (the “Report”). The Program assesses liquidity risk under both normal and reasonably foreseeable stressed market conditions. The risk is managed by monitoring the degree of liquidity of a fund’s investments, limiting the amount of illiquid investments and utilizing various risk management tools and facilities available to a fund, among other means. The Trust has engaged the services of ICE Data Services, a third-party vendor, to provide daily portfolio investment classification services to assist in the Program Administrator’s assessment. The Report noted that no material changes had been made to the Program during the review period. The Program Administrator determined that the Program is adequately designed and operating effectively.

The American Customer Satisfaction ETF reorganized into the Trust on May 24, 2021 and was not a part of the Report but has adopted the Program upon reorganization into the Trust.

American Customer Satisfaction ETF

APPROVAL OF INVESTMENT ADVISORY AGREEMENT (Unaudited)

The Board of Trustees (the “Board” or the “Trustees”) of Tidal ETF Trust (the “Trust”) met via video conference at a meeting held on March 24, 2021 to consider the initial approval of the Investment Advisory Agreement (the “Advisory Agreement”) between the Trust, on behalf of the American Customer Satisfaction ETF (the “Fund”), a proposed series of the Trust, and Toroso Investments, LLC, the Fund’s proposed investment adviser (the “Adviser”). Prior to this meeting, the Board requested and received materials to assist them in considering the approval of the Advisory Agreement. The materials provided contained information with respect to the factors enumerated below, including a copy of the Advisory Agreement, a memorandum prepared by the Trust’s outside legal counsel to the Trust and Independent Trustees discussing in detail the Trustees’ fiduciary obligations and the factors they should assess in considering the approval of the Advisory Agreement, due diligence materials relating to the Adviser (including the due diligence response completed by the Adviser with respect to a specific request letter from the Trust’s outside legal counsel to the Trust and Independent Trustees, the Adviser’s Form ADV, select ownership, organizational, financial and insurance information for the Adviser, biographical information of the Adviser’s key management and compliance personnel, detailed comparative information regarding the proposed unitary advisory fee for the Fund, and information regarding the Adviser’s compliance program) and other pertinent information. Based on their evaluation of the information provided, the Trustees, by a unanimous vote (including a separate vote of the Trustees who are not “interested persons,” as that term is defined in the Investment Company Act of 1940, as amended (the “Independent Trustees”)), approved the Advisory Agreement for an initial two-year term.

Discussion of Factors Considered

In considering the approval of the Advisory Agreement and reaching their conclusions, the Trustees reviewed and analyzed various factors that they determined were relevant, including the factors enumerated below.

1.Nature, extent and quality of services to be provided. The Board considered the nature, extent and quality of the Adviser’s overall services to be provided to the Fund as well as its specific responsibilities in all aspects of day-to-day investment management of the Fund. The Board considered the qualifications, experience and responsibilities of the Adviser’s investment management team, including Michael Venuto and Charles Ragauss, who will each serve as a portfolio manager of the Fund, as well as the responsibilities of other key personnel of the Adviser to be involved in the day to day activities of the Fund. The Board reviewed due diligence information provided by the Adviser, including information regarding the Adviser’s compliance program, its compliance personnel and compliance record, as well as the Adviser’s cybersecurity program and business continuity plan. The Board noted that the Adviser does not manage any other accounts that utilize a strategy similar to that to be employed by the Fund.

The Board also considered other services to be provided to the Fund, such as monitoring adherence to the Fund’s investment strategy and restrictions, monitoring compliance with various Fund policies and procedures and with applicable securities regulations, and monitoring the extent to which the Fund achieves its investment objective as a passively-managed ETF.

The Board concluded that the Adviser had sufficient quality and depth of personnel, resources, investment methods and compliance policies and procedures essential to performing its duties under the Advisory Agreement and managing the Fund and that the nature, overall quality and extent of the management services to be provided to the Fund, as well as the Adviser’s compliance program, were satisfactory.

2.Investment performance of the Fund and the Adviser. In assessing the portfolio management services to be provided by the Adviser, the Trustees considered the investment management experience of Mr. Ragauss, who will serve as a portfolio manager for the Fund. Because the Fund had not yet commenced operations and did not have its own performance history, the Trustees considered the performance of the American Customer Satisfaction ETF, a series of ETF Series Solutions (the “Predecessor Fund”), managed by Mr. Ragauss. The Trustees noted that the Fund will not commence operations until after the closing of the reorganization of the Predecessor Fund with and into the Fund, at which time the Fund will adopt the performance history of the Predecessor Fund. The Trustees compared the performance of the Predecessor Fund to its underlying index (the American Customer Satisfaction Investable Index (the “ACSI Index”)), its benchmark index (the S&P 500), and in comparison to a peer group of funds in the Predecessor Fund’s current Morningstar category as constructed by data presented by Morningstar Direct (a peer group of U.S. large blend funds), for the year-to-date, six-month, one-year, three-year and since inception periods ended February 28, 2021. The Board also considered that because the Fund is designed to track the performance of the ASCI Index, the performance of the Fund would not be the direct result of investment decisions made by the Adviser. However, with respect to the Fund’s performance, the Board in the future would focus on the Adviser’s trade execution services, including whether the Fund’s performance exhibited significant tracking error.

APPROVAL OF INVESTMENT ADVISORY AGREEMENT (Unaudited) (Continued)

After considering all of the information and noting that past performance is not a guarantee or indication of future results, the Trustees determined that the Fund and its shareholders were likely to benefit from the Adviser’s management.

3.Cost of services to be provided and profits to be realized by the Adviser. The Board considered the cost of services and the structure of the Adviser’s proposed advisory fee, including a review of comparative expenses, expense components and peer group selection. The Board took into consideration that the advisory fee was a “unitary fee,” meaning that the Fund would pay no expenses other than the advisory fee and certain other costs such as interest, brokerage and extraordinary expenses and, to the extent it is implemented, fees pursuant to the Fund’s Rule 12b 1 Plan. The Board noted that the Adviser agreed to pay all other expenses incurred by the Fund. The Board considered comparative information prepared by Fund Services utilizing data provided by Morningstar Direct relating to the cost structure of the Fund relative to a peer group. The Fund was compared to ETFs in the U.S. Fund Large Blend category.

The Board concluded that the Fund’s proposed expense ratio and the advisory fee to be paid to the Adviser were fair and reasonable in light of the comparative expense information and the investment management services to be provided to the Fund by the Adviser given the nature of the Fund’s strategy. The Board also evaluated, based on information provided by the Adviser, the compensation and benefits expected to be received by the Adviser and its affiliates from their relationship with the Fund, taking into account an analysis of the Adviser’s expected profitability with respect to the Fund. The Board further concluded that the Adviser had adequate financial resources to support its services to the Fund from the revenues of its overall investment advisory business.

4.Extent of economies of scale as the Fund grows. The Board considered the potential economies of scale that the Fund might realize under the structure of the proposed advisory fee. The Board noted the advisory fee did not contain any breakpoint reductions as the Fund’s assets grow in size, but that the Adviser would evaluate future circumstances that may warrant breakpoints in the fee structure.

5.The benefits to be derived from the relationship with the Fund. The Board considered the direct and indirect benefits that could be received by the Adviser and its affiliates from association with the Fund. The Board concluded that the benefits the Adviser may receive, such as greater name recognition or the ability to attract additional investor assets, appear to be reasonable and in many cases may benefit the Fund.

Conclusion. Based on the Board’s deliberations and its evaluation of the information described above, with no single factor determinative of a conclusion, the Board, including the Independent Trustees, unanimously concluded that: (a) the terms of the Advisory Agreement are fair and reasonable; (b) the advisory fee is reasonable in light of the services that the Adviser will provide to the Fund; and (c) the approval of the Advisory Agreement for an initial term of two years was in the best interests of the Fund and its shareholders.
