Alerian MLP ETF

INVESTMENT OBJECTIVE

The Alerian MLP ETF (the “Fund” or “AMLP”) seeks investment results that correspond (before fees and expenses) generally to the price and yield performance of its underlying index, the Alerian MLP Infrastructure Total Return Index (the “Underlying Index” or “AMZI”). The shares of the Fund are listed and trade on the NYSE Arca, Inc. (“NYSE”) under the ticker symbol AMLP. The Fund will normally invest at least 90% of its total assets in securities that comprise the Underlying Index.

The Underlying Index is a rules based, modified capitalization weighted, float-adjusted index intended to give investors a means of tracking the overall performance of the United States energy infrastructure Master Limited Partnership (“MLP”) asset class. The Underlying Index is comprised of energy infrastructure MLPs that earn a majority of their cash flow from the transportation, storage, and processing of energy commodities.

PERFORMANCE OVERVIEW

During the twelve-month period from December 1, 2020, to November 30, 2021, the Fund delivered a total return of 38.04% (37.97% NAV). This compares to the Fund’s Underlying Index, which increased 28.42% on a price-return basis and 39.34% on a total-return basis. The difference in performance between the AMZI and AMLP is primarily attributable to the Fund’s operating expenses and the tax impact of the Fund’s C-Corporation structure.

During the period, the Fund paid four distributions:

Distributions from AMZI constituents were largely stable during the Fund's fiscal year as reflected by steady payouts from the Fund. In the latest distribution announcements for 3Q21 (paid in 4Q21), four constituents grew their payouts sequentially – MPLX (MPLX), Magellan Midstream Partners (MMP), Western Midstream Partners (WES), and Cheniere Energy Partners (CQP) – and the other constituents maintained their payouts. MPLX also announced a special distribution for the quarter. This helped drive the increased Fund distribution in November 2021.

During the fiscal year, NGL Energy Partners (NGL) was removed from the Underlying Index during a quarterly rebalancing, while TC PipeLines (TCP) and Noble Midstream Partners (NBLX) were removed from the Underlying Index in relation to their acquisition by another entity. There were no updates to the Underlying Index methodology.

In 2021, energy infrastructure MLPs continued to recover from the pandemic-related headwinds that weighed on 2020 performance. The widespread availability of COVID-19 vaccines supported energy demand as daily activities resumed and travel increased. US energy production largely stabilized, as capital discipline by producers kept volume growth in check. Producer discipline and improving demand was supportive for commodity prices and energy stocks in turn. After starting 2021 below $50 per barrel (bbl), West Texas Intermediate (WTI) oil prices had reached $70/bbl by mid-year and a multi-year high of $85/bbl in October. Even after a significant late November sell-off on Omicron variant concerns, WTI oil prices were up 36.40% year-to-date through November 30, 2021. Natural gas prices also strengthened to multi-year highs in 2021, briefly touching $6 per million British thermal unit in October. Rising energy prices contributed to mounting inflation concerns as the year progressed, which also boded well for energy infrastructure MLPs given their real asset exposure and the inflation adjustments often built into their contracts.

In addition to a supportive energy macro backdrop, energy infrastructure MLPs benefitted from company-level tailwinds as well. Free cash flow remained in focus for AMZI constituents, with many generating free cash flow even after generous distributions. Excess cash flow has been deployed for debt reduction and returning cash to shareholders, with many constituents active with buybacks. As of November 30, nearly 70% of the AMZI by weighting has a buyback authorization in place. AMZI constituents have also made strides with reporting environmental, social and governance metrics, while also pursuing energy transition opportunities in areas like carbon capture and renewable fuels. An ongoing recovery in energy markets broadly and company-level tailwinds from strong free cash flow generation could lend continued support to energy infrastructure MLPs.

Performance (as of November 30, 2021)

Total Expense Ratio (per the current prospectus) is 0.90%.

Performance data quoted represents past performance. Past performance does not guarantee future results. Total return figures assume reinvestment of dividends, if any. The table does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when sold or redeemed, may be worth more or less than the original cost. Current performance data may be higher or lower than actual data quoted. For the most current month-end performance data please visit www.alpsfunds.com or call 1.877.398.8461. The Fund accrues deferred income taxes for future tax liabilities associated with the portion of MLP distributions considered to be a tax-deferred return of capital and for any net operating gains as well as capital appreciation of its investment. This deferred tax liability is reflected in the daily NAV and as a result the fund's after-tax performance could differ significantly from the underlying assets even if the pre-tax performance is closely tracked.

NAV is an exchange-traded fund’s per-share value. The per-share dollar amount of the Fund is derived by dividing the total value of all the securities in its portfolio, less any liabilities, by the number of Fund shares outstanding. Market Price is the price at which a share can currently be traded in the market. Information detailing the number of days the Market Price of the Fund was greater than the Fund’s NAV and the number of days it was less than the Fund’s NAV can be obtained at www.alpsfunds.com.

The Alerian MLP Infrastructure Total Return Index is comprised of 16 midstream energy Master Limited Partnerships and provides investors with an unbiased benchmark for the infrastructure component of this emerging asset class. Total return assumes reinvestment of any dividends and distributions realized during a given time period.

The Alerian MLP Total Return Index is recognized as a leading gauge of energy infrastructure Master Limited Partnerships (MLPs). The capped, float-adjusted, capitalization-weighted index, whose constituents earn the majority of their cash flow from midstream activities involving energy commodities, is reported on a total-return basis (AMZX), which assumes reinvestment of any dividends and distributions realized during a given period.

The index is not actively managed and does not reflect any deductions for fees, expenses or taxes. One cannot invest directly in an index. Index performance does not reflect fund performance.

The Fund’s shares are not individually redeemable. Investors buy and sell shares of the Fund on a secondary market. Only market makers or “authorized participants” may trade directly with the Fund, typically in blocks of 25,000 shares.

The Alerian MLP ETF is not suitable for all investors. Investments in the Fund are subject to investment risks, including possible loss of the principal amount invested.

Alerian Energy Infrastructure ETF

INVESTMENT OBJECTIVE

The Alerian Energy Infrastructure ETF (the “Fund” or “ENFR”) seeks investment results that correspond (before fees and expenses) generally to the price and yield performance of its underlying index, the Alerian Midstream Energy Select Total Return Index (the “Underlying Index” or “AMEI”). As a secondary objective, the Fund seeks to provide total return through income and capital appreciation. The Shares of the Fund are listed and trade on the NYSE Arca, Inc. (“NYSE”) under the ticker symbol ENFR. The Fund will normally invest at least 90% of its total assets in securities that comprise the Underlying Index.

The Underlying Index is a composite of North American energy infrastructure companies engaged in midstream activities involving energy commodities, including gathering and processing, liquefaction, pipeline transportation, rail terminaling, and storage (also known as “midstream energy businesses”). Midstream energy companies include midstream MLPs and midstream corporations, either based in the United States or Canada. The Underlying Index has a 25% limit for companies taxed as pass-through entities.

PERFORMANCE OVERVIEW

During the twelve-month period from December 1, 2020, to November 30, 2021, the Fund delivered a total return of 38.91% (38.93% NAV). This compares to the Fund’s Underlying Index, which increased 31.64% on a price-return basis and 40.13% on a total-return basis.

During the period, the Fund paid four quarterly distributions:

AMEI constituents largely maintained or increased their dividends during the fiscal year. In the latest distribution announcements for 3Q21 (paid in 4Q21), five constituents increased their payouts sequentially, and there were no dividend cuts for the quarter. The Fund’s February and November distributions were augmented by special dividends from Macquarie Infrastructure Corporation (MIC). MIC paid out special dividends of $11.00 per share in January and $37.39 per share in October as the company essentially sold itself in parts. Additionally, MPLX paid out a special distribution for 3Q21 that also contributed to the higher distribution from the Fund in November 2021.

During the fiscal year, Altus Midstream Company (ALTM) and Oasis Midstream Partners (OMP) were added to the Underlying Index while Delek Logistics Partners (DKL) was removed during quarterly rebalancings. Inter Pipeline (IPL CN) and Noble Midstream Partners (NBLX) were removed from the Underlying Index in relation to their acquisition by another entity. There were no updates to the Underlying Index methodology.

In 2021, energy infrastructure companies continued to recover from the pandemic-related headwinds that weighed on 2020 performance. The widespread availability of COVID-19 vaccines supported energy demand as daily activities resumed and travel increased. US energy production largely stabilized, as capital discipline by producers kept volume growth in check.

Even after a significant late November sell-off on Omicron variant concerns, WTI oil prices were up 36.40% year-to-date through November 30, 2021. Natural gas prices also strengthened to multi-year highs in 2021, briefly touching $6 per million British thermal unit in October. Rising energy prices contributed to mounting inflation concerns as the year progressed, which also boded well for energy infrastructure companies given their real asset exposure and the inflation adjustments often built into their contracts.

In addition to a supportive energy macro backdrop, energy infrastructure companies benefitted from company-level tailwinds as well. Free cash flow remained in focus for AMEI constituents, with many generating free cash flow even after generous dividends. Excess cash flow has been deployed for debt reduction and returning cash to shareholders, with many constituents active with buybacks. As of November 30, approximately 64% of the AMEI Index by weighting has a buyback authorization in place.

AMEI constituents have also made strides with reporting environmental, social and governance metrics, and multiple constituents have targets to achieve net-zero emissions by 2050. Constituents are also pursuing energy transition opportunities in areas like carbon capture, hydrogen, and renewable fuels. The large Canadian constituents, Enbridge (ENB) and TC Energy (TRP), have been particularly active on this front. An ongoing recovery in energy markets broadly and company-level tailwinds from strong free cash flow generation could lend continued support to energy infrastructure corporations and MLPs.

Shareholder Expense Example: As a shareholder of a Fund, you incur certain ongoing costs, including management fees and other Fund expenses. These examples are 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. It is based on an investment of $1,000 invested at the beginning of the (six month) period and held through November 30, 2021.

Actual Return: The first line of the table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you incurred 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 Period” to estimate the expenses attributable to your investment during this period.

Hypothetical 5% Return: The second line of the 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 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 other funds.

The expenses shown in the table are meant to highlight ongoing Fund costs only and do not reflect any transaction costs, such as brokerage commissions and other fees to financial intermediaries. Therefore, the second line 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 costs were included, your costs would have been higher.

To the Board of Trustees of ALPS ETF Trust and the shareholders of Alerian MLP ETF and Alerian Energy Infrastructure ETF:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statements of assets and liabilities, including the schedule of investments, of Alerian MLP ETF and Alerian Energy Infrastructure ETF (the "Funds"), two of the funds constituting the ALPS ETF Trust as of November 30, 2021, the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, and the related notes.

In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Funds as of November 30, 2021, and the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended in conformity with accounting principles generally accepted in the United States of America.

We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Funds are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Funds’ internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of November 30, 2021, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures.

1. ORGANIZATION

ALPS ETF Trust (the “Trust”), a Delaware statutory trust, is an open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). As of November 30, 2021, the Trust consisted of eighteen separate portfolios. Each portfolio represents a separate series of the Trust. This report pertains to the Alerian MLP ETF and the Alerian Energy Infrastructure ETF (each a “Fund” and collectively, the “Funds”).

The investment objective of the Alerian MLP ETF is to seek investment results that correspond (before fees and expenses) generally to the price and yield performance of its underlying index, the Alerian MLP Infrastructure Total Return Index. The investment objective of the Alerian Energy Infrastructure ETF is to seek investment results that correspond (before fees and expenses) generally to the price and yield performance of its underlying index, the Alerian Midstream Energy Select Total Return Index. The investment advisor uses a “passive management” or indexing investment approach to try to achieve each Fund’s investment objective. Each Fund is considered non-diversified and may invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

Each Fund’s Shares (“Shares”) are listed on the NYSE Arca, Inc. (“the NYSE Arca”). Each Fund issues and redeems Shares at net asset value (“NAV”), in blocks of 25,000 Shares, each of which is called a “Creation Unit”. Creation Units are issued and redeemed principally in-kind for securities included in the Underlying Index. Except when aggregated in Creation Units, Shares are not redeemable securities of the Fund. On October, 1, 2021, Alerian Energy Infrastructure ETF reduced its Creation Unit size from 50,000 to 25,000 shares.

The Board authorized a one-for-five reverse stock split of Alerian MLP ETF that was effective at the market open on May 18, 2020. The impact of the reverse stock split was to decrease the number of shares outstanding by a factor of five, while increasing the NAV of shares outstanding by a factor of five, resulting in no effect to the net assets of the Fund. The financial statements of the Fund have been adjusted to reflect the reverse stock split.

Pursuant to the Trust’s organizational documents, its Officers and Trustees are indemnified against certain liability arising out of the performance of their duties to the Trust. Additionally, in the normal course of business, the Trust enters into contracts with service providers that contain general indemnification clauses. The Trust’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Trust that have not yet occurred.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of the financial statements. The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates. Each Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946.

A. Portfolio Valuation

Each Fund’s NAV is determined daily, as of the close of regular trading on the New York Stock Exchange (“NYSE”), normally 4:00 p.m. Eastern Time, on each day the NYSE is open for trading. The NAV is computed by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding.

Portfolio securities listed on any exchange other than the NASDAQ Stock Market LLC (“NASDAQ”) are valued at the last sale price on the business day as of which such value is being determined. If there has been no sale on such day, the securities are valued at the mean of the most recent bid and ask prices on such day. Securities traded on the NASDAQ are valued at the NASDAQ Official Closing Price as determined by NASDAQ. Portfolio securities traded on more than one securities exchange are valued at the last sale price on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities. Portfolio securities traded in the over-the-counter market, but excluding securities traded on the NASDAQ, are valued at the latest quoted sale price in such market.

20 | November 30, 2021

Alerian Exchange Traded Funds

The Funds’ investments are valued at market value or, in the absence of market value with respect to any portfolio securities, at fair value according to procedures adopted by the Trust’s Board of Trustees (the “Board”). When market quotations are not readily available or when events occur that make established valuation methods unreliable, securities of the Funds may be valued in good faith by or under the direction of the Board. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market price is not available from a pre-established primary pricing source or the pricing source is not willing to provide a price; a security with respect to which an event has occurred that is most likely to materially affect the value of the security after the market has closed but before the calculation of the Funds’ NAV or make it difficult or impossible to obtain a reliable market quotation; or a security whose price, as provided by the pricing service, does not reflect the security’s “fair value” due to the security being de-listed from a national exchange or the security’s primary trading market is temporarily closed at a time when, under normal conditions, it would be open. As a general principle, the current “fair value” of a security would be the amount which the owner might reasonably expect to receive from the sale on the applicable exchange or principal market. A variety of factors may be considered in determining the fair value of such securities.

B. Fair Value Measurements

Each Fund discloses the classification of its fair value measurements following a three-tier hierarchy based on the inputs used to measure fair value. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability that are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability that are developed based on the best information available.

Valuation techniques used to value the Funds’ investments by major category are as follows:

Equity securities, including restricted securities, and Limited Partnerships for which market quotations are readily available, are valued at the last reported sale price or official closing price as reported by a third party pricing vendor on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. In the event there were no sales during the day or closing prices are not available, securities are valued at the mean of the most recent quoted bid and ask prices on such day and are generally categorized as Level 2 in the hierarchy. Investments in open-end mutual funds are valued at their closing NAV each business day and are categorized as Level 1 in the hierarchy.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy.

Various inputs are used in determining the value of the Funds’ investments as of the end of the reporting period. When inputs used fall into different levels of the fair value hierarchy, the level in the hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The designated input levels are not necessarily an indication of the risk or liquidity associated with these investments.

These inputs are categorized in the following hierarchy under applicable financial accounting standards:

21 | November 30, 2021

Alerian Exchange Traded Funds

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

Alerian MLP ETF

Alerian Energy Infrastructure ETF

The Funds did not have any securities that used significant unobservable inputs (Level 3) in determining fair value and there were no transfers into or out of Level 3 during the year ended November 30, 2021.

C. Foreign Currency Translation

The books and records of the Funds are maintained in U.S. dollars. Investment valuations and other assets and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. The portion of realized and unrealized gains or losses on investments due to fluctuations in foreign currency exchange rates is not separately disclosed and is included in realized and unrealized gains or losses on investments, when applicable.

D. Securities Transactions and Investment Income

Securities transactions are recorded as of the trade date. Realized gains and losses from securities transactions are recorded on the specific identification in accordance with GAAP. Dividend income and capital gains distributions, if any, are recorded on the ex-dividend date, net of any foreign taxes withheld. Interest income, if any, is recorded on the accrual basis, including amortization of premiums and accretion of discounts.

E. Dividends and Distributions to Shareholders

Each Fund intends to declare and make quarterly distributions, or as the Board may determine from time to time. Distributions of net realized capital gains earned by the Alerian Energy Infrastructure ETF, if any, are distributed at least annually. Distributions from net investment income and capital gains are determined in accordance with income tax regulations, which may differ from U.S. GAAP. These differences are primarily due to differing treatments of income and gains on various investment securities held by the Funds, timing differences and differing characterization of distributions made by the Funds.

Distributions received from each Fund’s investments in Master Limited Partnerships (“MLPs”) may be comprised of both income and return of capital. Each Fund records investment income and return of capital based on estimates made at the time such distributions are received. Such estimates are based on historical information available from each MLP and other industry sources. These estimates may subsequently be revised based on information received from MLPs after their tax reporting periods are concluded.

The Funds each expect a portion of its distributions to shareholders might be comprised of tax deferred return of capital. Return of capital distributions are not taxable income to the shareholder, but reduce the investor’s tax basis in the investor’s Fund Shares. Such a reduction in tax basis will result in larger taxable gains and/or lower tax losses on a subsequent sale of Fund Shares. Shareholders who periodically receive the payment of dividends or other distributions consisting of a return of capital may be under the impression that they are receiving net profits from the Funds when, in fact, they are not. Shareholders should not assume that the source of the distributions is from the net profits of the Funds.

F. Federal Income Taxation and Tax Basis Information

Alerian MLP ETF

The Fund is taxed as a regular C-corporation for federal income tax purposes and as such is obligated to pay federal and state income tax. This treatment differs from most investment companies, which elect to be treated as “regulated investment companies” under the Internal Revenue Code of 1986, as amended (the “Code”) in order to avoid paying entity level income taxes. Under current law, the Fund is not eligible to elect treatment as a regulated investment company due to its investments primarily in MLPs invested in energy assets. The Fund expects that substantially all of the distributions it receives from MLPs may be treated as a tax-deferred return of capital, thus reducing the Fund’s current tax liability. However, the amount of taxes paid by the Fund will vary depending on the amount of income and gains derived from investments and/or sales of MLP interests and such taxes will reduce your return from an investment in the Fund.

Since the Fund will be subject to taxation on its taxable income, the NAV of the Fund shares will also be reduced by the accrual of any deferred tax liabilities. The Underlying Index however is calculated without any deductions for taxes. As a result, the Fund's after tax performance could differ significantly from the Underlying Index even if the pretax performance of the Fund and the performance of Underlying Index are closely related.

Cash distributions from MLPs to the Fund that exceed the Fund’s allocable share of such MLP’s net taxable income are considered a tax deferred return of capital that will reduce the Fund’s adjusted tax basis in the equity securities of the MLP. These reductions in the Fund’s adjusted tax basis in the MLP equity securities will increase the amount of any taxable gain (or decrease the amount of any tax loss) recognized by the Fund on a subsequent sale of the securities. The Fund will accrue deferred income taxes for any future tax liability associated with (i) that portion of MLP distributions considered to be a tax-deferred return of capital as well as (ii) capital appreciation of its investments. Upon the sale of an MLP security, the Fund may be liable for previously deferred taxes. The Fund will rely to some extent on information provided by the MLPs, which is not necessarily timely, to estimate the deferred tax liability for purposes of financial statement reporting and determining the Fund’s NAV. From time to time, the Adviser will modify the estimates or assumptions related to the Fund’s deferred tax liability as new information becomes available. The Fund will generally compute deferred income taxes based on the federal income tax rate applicable to corporations and an assumed rate attributable to state taxes.

The Fund’s income tax expense/(benefit) consists of the following:

Deferred income taxes reflect the net tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting and tax purposes.

Components of the Fund’s deferred tax assets and liabilities are as follows:

Due to the activities of the MLPs that the fund is invested in, the Fund is required to pay franchise tax in certain states. Generally speaking, franchise tax expense is a tax on equity of a corporation, or base minimum fees, imposed by various jurisdictions. The amounts of the tax are estimated throughout the year based upon the Fund's estimate of underlying activities conducted in the states and reconciled to actual amounts paid upon the filing of the tax returns for the states. These taxes are paid as either estimated tax payments, extension payments, or with the tax return filings of the various states.

The capital loss carryforward is available to offset future taxable income. The capital loss can be carried forward for 5 years and, accordingly, would begin to expire as of November 30, 2022. The Fund has net capital loss carryforwards for federal income tax purposes as follows:

The net operating loss carryforward is available to offset future taxable income. The Fund has net operating loss carryforwards for federal income tax purposes as follows:

The Fund also has state tax net operating loss carryforwards of various amounts per state. The Deferred Tax Assets associated with these state tax net operating losses are as follows:

The Tax Cuts and Jobs Act (“TCJA”) was signed into law on December 22, 2017. The TCJA made modifications to the net operating loss (“NOL”) deduction. The TCJA eliminated the NOL carryback ability and replaced the 20 year carryforward period with an indefinite carryforward period for any NOLs arising in tax years beginning after December 31, 2017. The TCJA also established a limitation for any NOLs generated in tax years beginning after December 31, 2017 to the lesser of the aggregate of available NOLs or 80% of taxable income before any NOL utilization. The Coronavirus Aid, Relief, and Economic Stability Act (“CARES Act”) was signed into law on March 27, 2020. The CARES Act delays the application of the 80% net operating loss limitation, established under TCJA, to tax years ending November 30, 2022 and beyond.

The Fund reviews the recoverability of its deferred tax assets based upon the weight of available evidence. When assessing the recoverability of its deferred tax assets, significant weight was given to the effects of potential future realized and unrealized gains on investments and the period over which these deferred tax assets can be realized. Currently, any capital losses that may be generated by the Fund are eligible to be carried back up to three years and can be carried forward for five years to offset capital gains recognized by the Fund in those years.

Based upon the Fund’s assessment, it has determined that it is “more-likely-than-not” that a portion of its deferred tax assets will not be realized through future taxable income of the appropriate character. Accordingly, a valuation allowance has been established for the Fund’s deferred tax assets. The Fund will continue to assess the need for a valuation allowance in the future. Significant increases in the fair value of its portfolio of investments may change the Fund’s assessment of the recoverability of these assets and may result in the removal of the valuation allowance against all or a portion of the Fund’s gross deferred tax assets.

Total income tax expense/(benefit) (current and deferred) differs from the amount computed by applying the federal statutory income tax rate of 21% to net investment income and realized and unrealized gain/(losses) on investment before taxes as follows:

The following is a tabular reconciliation of the total amounts of unrecognized tax benefits:

The Fund recognizes interest accrued related to unrecognized tax benefits and penalties as income tax expense. For the year ended November 30, 2021, the Fund paid $12,356 in penalties and interest.

The Fund recognizes the tax benefits of uncertain tax positions only where the position is “more-likely-than-not” to be sustained assuming examination by tax authorities. Management has analyzed the Fund’s tax positions, and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on U.S. tax returns and state tax returns filed since inception of the Fund. Tax periods ended November 30, 2018 through November 30, 2020 remain subject to examination by tax authorities in the United States. Due to the nature of the Fund’s investments, the Fund may be required to file income tax returns in several states. 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 in the next 12 months.

Alerian Energy Infrastructure ETF

The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. GAAP. Reclassifications are made to the Fund’s capital accounts for permanent tax differences to reflect income and gains available for distribution (or available capital loss carryforwards) under income tax regulations.

No provision for income taxes is included in the accompanying financial statements, as the Alerian Energy Infrastructure ETF intends to distribute to shareholders all taxable investment income and realized gains and otherwise comply with Subchapter M of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies. The Alerian Energy Infrastructure ETF evaluates tax positions taken (or expected to be taken) in the course of preparing the Fund’s tax returns to determine whether these positions meet a “more-likely-than-not” standard that, based on the technical merits, have a more than fifty percent likelihood of being sustained by a taxing authority upon examination. A tax position that meets the “more-likely-than-not” recognition threshold is measured to determine the amount of benefit to recognize in the financial statements.

As of and during the year ended November 30, 2021, the Alerian Energy Infrastructure ETF did not have a liability for any unrecognized tax benefits. The Alerian Energy Infrastructure ETF files U.S. federal, state, and local tax returns as required. The Fund’s tax returns are subject to examination by the relevant tax authorities until expiration of the applicable statute of limitations, which is generally three years after the filing of the tax return, but may extend to four years in certain jurisdictions. Tax returns for open years have incorporated no uncertain tax positions that require a provision for income taxes.

For the year ended November 30, 2021, permanent book and tax differences resulting primarily from differing treatment of investments in partnerships and redemptions in kind were identified and reclassified among components of the Fund’s net assets as follows:

The tax character of the distributions paid during the fiscal year ended November 30, 2021 and November 30, 2020 was as follows:

The character of distributions made during the year may differ from its ultimate characterization for federal income tax purposes.

Under current law, capital losses maintain their character as short-term or long-term and are carried forward to the next tax year without expiration. As of November 30, 2021, the following amounts are available as carry forwards to the next tax year:

As of November 30, 2021, the components of distributable earnings on a tax basis were as follows:

As of November 30, 2021, the costs of investments for federal income tax purposes and accumulated net unrealized appreciation/(depreciation) on investments were as follows:

The difference between cost amounts for financial statement purposes is due primarily to the recognition of pass-through income from a Fund’s investments in master limited partnerships and wash sales.

G. Lending of Portfolio Securities

The Alerian Energy Infrastructure ETF has entered into a securities lending agreement with State Street Bank & Trust Co. (“SSB”), the Fund’s lending agent. The Fund may lend its portfolio securities only to borrowers that are approved by SSB. The Fund will limit such lending to not more than 33 1/3% of the value of its total assets. The Fund’s securities held at SSB as custodian shall be available to be lent except those securities the Fund or ALPS Advisors, Inc. specifically identifies in writing as not being available for lending. The borrower pledges and maintains with the Fund collateral consisting of cash (U.S. Dollars only), securities issued or guaranteed by the U.S. government or its agencies or instrumentalities, and cash equivalents (including irrevocable bank letters of credit) issued by a person other than the borrower or an affiliate of the borrower. The initial collateral received by the Fund is required to have a value of no less than 102% of the market value of the loaned securities for U.S equity securities and a value of no less than 105% of the market value for non-U.S. equity securities. The collateral is maintained thereafter, at a market value equal to not less than 102% of the current value of the U.S. equity securities on loan and not less than 105% of the current value of the non-U.S. equity securities on loan. The market value of the loaned securities is determined at the close of each business day and any additional required collateral is delivered to the Fund on the next business day. During the term of the loan, the Fund is entitled to all distributions made on or in respect of the loaned securities. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the customary time period for settlement of securities transactions.

Alerian Exchange Traded Funds

Any cash collateral received is reinvested in a money market fund managed by SSB as disclosed in the Fund’s Schedule of Investments and is reflected in the Statements of Assets and Liabilities as a payable for collateral upon return of securities loaned. Non-cash collateral, in the form of securities issued or guaranteed by the U.S. government or its agencies or instrumentalities, is not disclosed in the Fund’s Statements of Assets and Liabilities as it is held by the lending agent on behalf of the Fund, and the Fund does not have the ability to re-hypothecate these securities. Income earned by the Fund from securities lending activity is disclosed in the Statement of Operations.

The following is a summary of the Fund's securities lending agreement and related cash and non-cash collateral received as of November 30, 2021:

The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, the Fund benefits from a borrower default indemnity provided by SSB. SSB’s indemnity allows for full replacement of securities lent wherein SSB will purchase the unreturned loaned securities on the open market by applying the proceeds of the collateral, or to the extent such proceeds are insufficient or the collateral is unavailable, SSB will purchase the unreturned loan securities at SSB’s expense. However, the Fund could suffer a loss if the value of the investments purchased with cash collateral falls below the value of the cash collateral received.

The following table reflects a breakdown of transactions accounted for as secured borrowings, the gross obligation by the type of collateral pledged or securities loaned, and the remaining contractual maturity of those transactions as of November 30, 2021:

3. INVESTMENT ADVISORY FEE AND OTHER AFFILIATED TRANSACTIONS

ALPS Advisors, Inc. (the “Adviser”) serves as the Funds’ investment adviser pursuant to an Investment Advisory Agreement with the Trust on behalf of each Fund (the “Advisory Agreement”). Pursuant to the Advisory Agreement, each Fund pays the Adviser an annual management fee for the services and facilities it provides, payable on a monthly basis as a percentage of the relevant Fund’s average daily net assets as set out below.

27 | November 30, 2021

Alerian Exchange Traded Funds

Out of the unitary management fees, the Adviser pays substantially all expenses of each Fund, including the cost of transfer agency, custody, fund administration, legal, audit, trustees and other services, except for interest expenses, distribution fees or expenses, brokerage expenses, taxes and extraordinary expenses not incurred in the ordinary course of each Fund's business. The Adviser’s unitary management fee is designed to pay substantially all of each Fund’s expenses and to compensate the Adviser for providing services for each Fund.

ALPS Fund Services, Inc., an affiliate of the Adviser, is the administrator of the Funds.

Each Trustee receives (1) a quarterly retainer of $10,000, (2) a per meeting fee of $5,000, (3) $1,500 for any special meeting held outside of a regularly scheduled board meeting, and (4) reimbursement for all reasonable out-of-pocket expenses relating to attendance at meetings. In addition, the Chairman of the Board and Chairman of the Audit Committee each receives a quarterly retainer of $2,000, in connection with their respective roles.

4. PURCHASES AND SALES OF SECURITIES

For the year ended November 30, 2021, the cost of purchases and proceeds from sales of investment securities, excluding short-term investments and in-kind transactions, were as follows:

For the year ended November 30, 2021, the cost of in-kind purchases and proceeds from in-kind sales were as follows:

For the year ended November 30, 2021, the Alerian Energy Infrastructure ETF had in-kind net realized gain of $2,600,602.

Gains on in-kind transactions are not considered taxable for federal income tax purposes and losses on in-kind transactions are also not deductible for tax purposes.

5. MASTER LIMITED PARTNERSHIPS

MLPs are publicly traded partnerships engaged in, among other things, the transportation, storage and processing of minerals and natural resources, and are treated as partnerships for U.S. federal income tax purposes. By confining their operations to these specific activities, their interests, or units, are able to trade on public securities exchanges exactly like the shares of a corporation, without entity level taxation. To qualify as a MLP and to not be taxed as a corporation, a partnership must receive at least 90% of its income from qualifying sources as set forth in Section 7704(d) of the Code. These qualifying sources include, among other things, natural resource-based activities such as the processing, transportation and storage of mineral or natural resources. MLPs generally have two classes of owners, the general partner and limited partners. The general partner of an MLP is typically owned by a major energy company, an investment fund, the direct management of the MLP, or is an entity owned by one or more of such parties. The general partner may be structured as a private or publicly traded corporation or other entity. The general partner typically controls the operations and management of the MLP through an up to 2% equity interest in the MLP plus, in many cases, ownership of common units and subordinated units. Limited partners typically own the remainder of the partnership, through ownership of common units, and have a limited role in the partnership’s operations and management.

MLPs are typically structured such that common units and general partner interests have first priority to receive quarterly cash distributions up to an established minimum amount (“minimum quarterly distributions” or “MQD”). Common and general partner interests also accrue arrearages in distributions to the extent the MQD is not paid. Once common and general partner interests have been paid, subordinated units receive distributions of up to the MQD; however, subordinated units do not accrue arrearages. Distributable cash in excess of the MQD is distributed to both common and subordinated units and generally on a pro rata basis. The general partner is also eligible to receive incentive distributions if the general partner operates the business in a manner which results in distributions paid per common unit surpassing specified target levels. As the general partner increases cash distributions to the limited partners, the general partner receives an increasingly higher percentage of the incremental cash distributions.

6.  CAPITAL SHARE TRANSACTIONS

Shares are created and redeemed by each Fund only in Creation Unit size aggregations of 25,000 Shares. On October 1, 2021, Alerian Energy Infrastructure ETF reduced its Creation Unit size from 50,000 to 25,000 Shares. Only broker-dealers or large institutional investors with creation and redemption agreements called Authorized Participants (“AP”) are permitted to purchase or redeem Creation Units from the Funds. Such transactions are generally permitted on an in-kind basis, with a balancing cash component to equate the transaction to the NAV per unit of each Fund on the transaction date. Cash may be substituted equivalent to the value of certain securities generally when they are not available in sufficient quantity for delivery, not eligible for trading by the AP or as a result of other market circumstances.

7.  RELATED PARTY TRANSACTIONS

The Funds engaged in cross trades between other funds in the Trust during the year ended November 30, 2021 pursuant to Rule 17a-7 under the 1940 Act. Cross trading is the buying or selling of portfolio securities between funds to which the Adviser serves as the investment adviser. The Board previously adopted procedures that apply to transactions between the Funds of the Trust pursuant to Rule 17a-7. These transactions related to cross trades during the period complied with the requirements set forth by Rule 17a-7 and the Trust’s procedures.

Transactions related to cross trades during the year ended November 30, 2021, were as follows:

8.  AFFILIATED COMPANIES

As defined by the Investment Company Act of 1940, an affiliated person, including an affiliated company, is one in which a Fund owns 5% or more of the outstanding voting securities, or a company which is under common ownership or control with the Fund.

For the year ended November 30, 2021, the Alerian MLP ETF held shares in the following affiliates, as defined by the Investment Company Act of 1940.

9. MARKET DISRUPTIONS RISK

The Funds are subject to investment and operational risks associated with financial, economic and other global market developments and disruptions, including the recent spread of an infectious respiratory illness caused by a novel strain of coronavirus (known as COVID-19), which can negatively impact the securities markets and cause each Fund to lose value.

The spread of COVID-19 has caused volatility, severe market dislocations and liquidity constraints in many markets, including markets for the securities each Fund holds, and may adversely affect each Fund’s investments and operations. The transmission of COVID-19 and efforts to contain its spread have resulted in travel restrictions and disruptions, closed international borders, enhanced health screenings at ports of entry and elsewhere, disruption of and delays in healthcare service preparation and delivery, quarantines, event and service cancellations or interruptions, disruptions to business operations and supply chains, and a reduction in consumer and business spending, as well as general concern and uncertainty that has negatively affected the economy. These disruptions have led to instability in the market place and the jobs market. The impact of COVID-19 could adversely affect the economies of many nations or the entire global economy, the financial well-being and performance of individual issuers, borrowers and sectors and the health of the markets generally in potentially significant and unforeseen ways.

The foregoing could lead to a significant economic downturn or recession, increased market volatility, a greater number of market closures, higher default rates and adverse effects on the values and liquidity of each Fund’s securities or other assets. Such impacts may adversely affect the performance of the Funds.
