NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

The TappAlpha SPY Growth & Daily Income ETF (the "Fund") is a non-diversified series of ETF Opportunities Trust, a Delaware statutory trust (the "Trust") which was organized on March 18, 2019 and is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company. The offering of the Fund's shares is registered under the Securities Act of 1933, as amended. The Fund commenced operations on August 15, 2024.

The Fund's investment objective is to seek current income while maintaining prospects for capital appreciation. The Fund's secondary investment objective is to seek exposure to the performance of the SPDR S&P 500® ETF Trust ("SPY"), subject to a limit on potential investment gains.

The Fund is deemed to be an individual reporting segment and is not part of a consolidated reporting entity. The objective and strategy of the Fund is used by Tapp Finance, Inc. d/b/a TappAlpha (the "Advisor") to make investment decisions, and the results of the Fund's operations, as shown in its Statement of Operations and Financial Highlights, is the information utilized for the day-today management of the Fund. Due to the significance of oversight and its role in the Fund's management, the Advisor's portfolio manager is deemed to be the Chief Operating Decision Maker.

The following is a summary of significant accounting policies consistently followed by the Fund. The policies are in conformity with accounting principles generally accepted in the United States of America ("GAAP"). The Fund follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 946 "Financial Services - Investment Companies".

Security Valuation

The Fund records investments at fair value. Generally, the Fund's domestic securities (including underlying ETFs which hold portfolio securities primarily listed on foreign (non-U.S.) exchanges) are valued each day at the last quoted sales price on each security's primary exchange. Securities traded or dealt in upon one or more securities exchanges for which market quotations are readily available and not subject to restrictions against resale are valued at the last quoted sales price on the primary exchange or, in the absence of a sale on the primary exchange, at the mean between the current bid and ask prices on such exchange. If market quotations are not readily available, securities will be

8

FINANCIAL STATEMENTS | June 30, 2025

TappAlpha SPY Growth & Daily Income ETF

Notes to Financial Statements - continuedJune 30, 2025 (unaudited)​

valued at their fair market value as determined in good faith under procedures approved by the Trust's Board of Trustees (the "Board"). Although the Board is ultimately responsible for fair value determinations under Rule 2a-5 of the 1940 Act, the Board has delegated day-to-day responsibility for oversight of the valuation of the Fund's assets to the Advisor as the Valuation Designee pursuant to the Fund's policies and procedures. Securities that are not traded or dealt in any securities exchange (whether domestic or foreign) and for which over-the-counter market quotations are readily available generally are valued at the last sale price or, in the absence of a sale, at the mean between the current bid and ask price on such over-the-counter market.

The Fund has a policy that contemplates the use of fair value pricing to determine the net asset value ("NAV") per share of the Fund when market prices are unavailable as well as under special circumstances, such as: (i) if the primary market for a portfolio security suspends or limits trading or price movements of the security; and (ii) when an event occurs after the close of the exchange on which a portfolio security is principally traded, but prior to the time as of which the Fund's NAV is calculated, that is likely to have changed the value of the security.

When the Fund uses fair value pricing to determine the NAV per share of the Fund, securities will not be priced on the basis of quotations from the primary market in which they are traded, but rather may be priced by another method that the Valuation Designee believes accurately reflects fair value. Any method used will be approved by the Board and results will be monitored to evaluate accuracy. The Fund's policy is intended to result in a calculation of the Fund's NAV that fairly reflects security values as of the time of pricing.

Accounting standards establish an authoritative definition of fair value and set out a hierarchy for measuring fair value. These standards require additional disclosures about the various inputs used to develop the measurements of fair value, which are summarized in the three broad levels listed below.

Various inputs are used in determining the value of the Fund's investments. GAAP established a three-tier hierarchy of inputs to establish a classification of fair value measurements for disclosure purposes. Level 1 includes quoted prices in active markets for identical securities. Level 2 includes other significant observable market-based inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.). Level 3 includes significant unobservable inputs (including the Fund's own assumptions in determining fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the level of inputs used to value the Fund's investments as of June 30, 2025:

Refer to the Fund's Schedule of Investments for a listing of the securities by type and sector. The Fund held no Level 3 securities at any time during the six months ended June 30, 2025.

Cash at Brokers

Cash at brokers is held as collateral for options written. As of June 30, 2025, $33,071 were cash deposits with a broker.

Security Transactions and Income

Security transactions are accounted for on the trade date. The cost of securities sold is determined generally on specific identification basis. Realized gains and losses from security transactions are determined on the basis of identified cost for book and tax purposes. Dividends are recorded on the ex-dividend date. Interest income is recorded on an accrual basis.

Accounting Estimates

In preparing financial statements in conformity with GAAP, management makes 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, as well as the reported amounts of investment income and expenses during the reporting period. Actual results could differ from those estimates.

Notes to Financial Statements - continuedJune 30, 2025 (unaudited)​

Federal Income Taxes

The Fund intends to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income to its shareholders. The Fund also intends to distribute sufficient net investment income and net capital gains, if any, so that it will not be subject to excise tax on undistributed income and gains. Therefore, no federal income tax or excise provision is required.

Management has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken in the Fund's tax returns. The Fund has no examinations in progress and management is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. Interest and penalties, if any, associated with any federal or state income tax obligations are recorded as income tax expense as incurred.

Reclassification of Capital Accounts

GAAP requires that certain components of net assets relating to permanent differences be reclassified between financial and tax reporting. For the six months ended June 30, 2025, there were no such reclassifications.

Dividends and Distributions

Dividends from net investment income, if any, are declared and paid at least monthly by the Fund. The Fund distributes its net realized capital gains, if any, to shareholders annually. The Fund may also pay a special distribution at the end of a calendar year to comply with federal tax requirements. All distributions are recorded on the ex-dividend date.

Creation Units

The Fund issues and redeems shares to certain institutional investors (typically market makers or other broker-dealers) only in large blocks of at least 10,000 shares known as "Creation Units." Purchasers of Creation Units ("Authorized Participants") will be required to pay to U.S. Bank, N.A. (the "Custodian") a fixed transaction fee ("Creation Transaction Fee") in connection with creation orders that is intended to offset the transfer and other transaction costs associated with the issuance of Creation Units. The standard Creation Transaction Fee will be the same regardless of the number of Creation Units purchased by an investor

11

FINANCIAL STATEMENTS | June 30, 2025

TappAlpha SPY Growth & Daily Income ETF

Notes to Financial Statements - continuedJune 30, 2025 (unaudited)​

on the applicable Business Day. The Creation Transaction Fee charged by the Custodian for each creation order is $300. Authorized Participants wishing to redeem shares will be required to pay to the Custodian a fixed transaction fee ("Redemption Transaction Fee") to offset the transfer and other transaction costs associated with the redemption of Creation Units. The standard Redemption Transaction Fee will be the same regardless of the number of Creation Units redeemed by an investor on the applicable Business Day. The Redemption Transaction Fee charged by the Custodian for each redemption order is $300.

Except when aggregated in Creation Units, shares are not redeemable securities. Shares of the Fund 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 ("DTC") participant and, in each case, must have executed an agreement with the Fund's principal underwriter (the "Distributor") with respect to creations and redemptions of Creation Units ("Participation Agreement"). Most retail investors will not qualify as Authorized Participants or have the resources to buy and sell whole Creation Units. Therefore, they will be unable to purchase or redeem the shares directly from the Fund. Rather, most retail investors will purchase shares in the secondary market with the assistance of a broker and will be subject to customary brokerage commissions or fees. The following table discloses the Creation Unit breakdown based on the NAV as of June 30, 2025:

To the extent contemplated by a participant agreement, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the shares comprising a Creation Unit to be redeemed to the Distributor, on behalf of the Fund, by the time as set forth in a participant agreement, the Distributor may nonetheless accept the redemption request in reliance on the undertaking by the Authorized Participant to deliver the missing shares as soon as possible, which undertaking shall be secured by the Authorized Participant's delivery and maintenance of collateral equal to a percentage of the value of the missing shares as specified in the participant agreement. A participant agreement may permit the Fund to use such collateral to purchase the missing shares, and could subject an Authorized Participant to liability for any shortfall between the cost of the Fund acquiring such shares and

the value of the collateral. Amounts are disclosed as Segregated Cash Balance from Authorized Participants for Deposit Securities and Collateral Payable upon Return of Deposit Securities on the Statement of Assets and Liabilities, when applicable.

Derivatives

The Fund is an actively managed exchange-traded fund ("ETF") that seeks to achieve its investment objectives through the use of a call option strategy that combines a long position in SPY, an exchange-traded fund designed to track the performance of the S&P 500® Index, with short positions in certain call options. The strategy is a daily covered call option strategy that sells "out of the money" call options with zero days to expiration each day, known as a "daily call". Daily call options having zero days to expiration are also known as "0DTE" options. In general, an option is a contract that gives the purchaser of the option, in return for a premium, the right to buy from the seller (writer) of the option the security underlying the option at a specified exercise price (the "strike price") at a specified expiration date. Through this call option strategy, the Fund sells or "writes" exchange-traded call options to generate income from option premiums. These may include but are not limited to selling call options on SPY, or selling call options on the S&P 500 Index ("SPX") or selling Cboe Mini-SPX Index call options ("XSP"). XSP options are designed to track the S&P 500 Index but trade at a smaller size compared to a standard SPX options contract.

The following are the derivatives held by the Fund on June 30, 2025:

*Statement of Assets and Liabilities location: Options written at value.

The effect of derivative instruments on the Statement of Operations and whose underlying risk exposure is equity price risk for the six months ended June 30, 2025, is as follows:

*Statement of Operations location: Net realized gain (loss) on options written.

**Statement of Operations location: Net change in unrealized appreciation (depreciation) on options written.

Officers and Trustees Indemnification

Under the Trust's organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Fund. In addition, in the normal course of business, the Fund enters into contracts with its vendors and others that provide for general indemnifications. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund. However, based on experience, the Fund expects that risk of loss to be remote.

NOTE 4 - DISTRIBUTIONS TO SHAREHOLDERS AND TAX COMPONENTS OF CAPITAL

Distributions are determined on a tax basis and may differ from net investment income and realized capital gains for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain or loss are recognized in different periods for financial statement and tax purposes; these differences will reverse at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes. The tax character of distributions paid during the six months ended June 30, 2025 and period ended December 31, 2024, were as follows:
