**1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES** 

The RBB Fund, Inc. ("RBB" or the "Company") was incorporated under the laws of the State of Maryland on February 29, 1988 and is registered under the Investment Company Act of 1940, as amended, (the "1940 Act"), as an open-end management investment company. RBB is a "series fund," which is a mutual fund divided into separate portfolios. Each portfolio is treated as a separate entity for certain matters under the 1940 Act, and for other purposes, and a shareholder of one portfolio is not deemed to be a shareholder of any other portfolio. Currently, RBB has 71 separate investment portfolios, including the SGI Enhanced Market Leader ETF (the "Fund").

Effective as of the close of business on May 2, 2025, the Chestnut Street Exchange Fund (the "Predecessor Fund"), an open-end management investment company established as a California Limited Partnership, was reorganized into the Fund as a new series of RBB in a tax-free reorganization (the "Reorganization"). The Fund acquired all the assets and liabilities of the Predecessor Fund in exchange for shares of the Fund, which were distributed pro rata by the Predecessor Fund to its shareholders in complete liquidation and termination of the Predecessor Fund. The agreement and plan of reorganization pursuant to which the Reorganization was accomplished was approved by shareholders of the Predecessor Fund on April 9, 2025. The Predecessor Fund commenced operations on December 29, 1976. As a result of the Reorganization, the performance and accounting history of the Predecessor Fund was assumed by the Fund.

As a tax-free reorganization, any unrealized appreciation or depreciation on the securities held by the Predecessor Fund on the date of Reorganization was treated as a non-taxable event, thus the cost basis of the securities held reflects their historical cost basis as of the date of Reorganization. As a result of the Reorganization, the Fund is the accounting successor. The Reorganization was accomplished by a tax-free exchange of the Fund's shares and value of net assets for the same shares and value of the Predecessor Fund's shares. 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 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. Immediately prior to the Reorganization, the net assets, fair value of investments, net unrealized appreciation and fund shares outstanding of the Predecessor Fund were as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Net Assets** | **Fair Value of <br> Investments** | **Net Unrealized <br> Appreciation** | **Fund Shares <br> Outstanding** |
| $166962449 | $166921998 | $146065549 | 6175830 |

---

RBB has authorized capital of one hundred billion shares of common stock of which 94.823 billion shares are currently classified into two hundred and fifty-five classes of common stock. Each class represents an interest in an active or inactive RBB investment portfolio.

The investment objective of the Fund is to seek capital appreciation and current income.

The Fund is an investment company and follows accounting and reporting guidance in the Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 946 "Financial Services - Investment Companies."

The end of the reporting period for the Fund is June 30, 2025, and the period covered by these Notes to Financial Statements is the six months ended June 30, 2025 (the "current fiscal period").

**PORTFOLIO VALUATION** – The Fund's net asset value ("NAV") is calculated once daily at the close of regular trading hours on the New York Stock Exchange ("NYSE") (generally 4:00 p.m. Eastern time) on each day the NYSE is open. Securities held by the Fund are valued using the closing price or the last sale price on a national securities exchange or the National Association of Securities Dealers Automatic Quotation System ("NASDAQ") market system where they are primarily traded. Equity securities traded in the over-the-counter ("OTC") market are valued at their closing prices. If there were no transactions on that day, securities traded principally on an exchange or on NASDAQ will be valued at the mean of the last bid and ask prices prior to the market close. Fixed income securities are valued using an independent pricing service, which considers such factors as security prices, yields, maturities and ratings, and

**SGI** **Enhanced Market Leaders** **ETF** 

**Notes to Financial Statements (Continued)** 

**June 30, 2025 (Unaudited)**

are deemed representative of market values at the close of the market. Investments in exchange-traded funds ("ETFs") are valued at their last reported sale price. Investments in other open-end investment companies, if any, are valued based on the NAV of those investment companies (which may use fair value pricing as disclosed in their prospectuses). Options for which the primary market is a national securities exchange are valued at the last sale price on the exchange on which they are traded, or, in the absence of any sale, will be valued at the mean of the last bid and ask prices prior to the market close. Options not traded on a national securities exchange are valued at the last quoted bid price for long option positions and the closing ask price for short option positions. Futures contracts are generally valued using the settlement price determined by the relevant exchange. If market quotations are unavailable or deemed unreliable, securities will be valued by the Valuation Designee (as defined below) in accordance with procedures adopted by the Company's Board of Directors (the "Board" or "Directors"). Relying on prices supplied by pricing services or dealers or using fair valuation may result in values that are higher or lower than the values used by other investment companies and investors to price the same investments.

The Board has adopted a pricing and valuation policy for use by each Fund and its Valuation Designee (as defined below) in calculating the Fund's NAV. Pursuant to Rule 2a-5 under the 1940 Act, the Board has designated Summit Global Investments, LLC (the "Adviser" or "Summit") as its "Valuation Designee" to perform all of the fair value determinations as well as to perform all of the responsibilities that may be performed by the Valuation Designee in accordance with Rule 2a-5. The Valuation Designee is authorized to make all necessary determinations of the fair values of portfolio securities and other assets for which market quotations are not readily available or if it is deemed that the prices obtained from brokers and dealers or independent pricing services are unreliable.

**FAIR VALUE MEASUREMENTS** — The inputs and valuation techniques used to measure the fair value of the Fund's investments are summarized into three levels as described in the hierarchy below:

● Level 1 — Prices are determined using quoted prices in active markets for identical securities.

● Level 2 — Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).

● Level 3 — Prices are determined using significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments).

The inputs or methodologies 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 inputs used, as of the end of the current fiscal period, in valuing each Fund's investments carried at fair value:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **Level 1** | **Level 2** | **Level 3** | **Total** |
|  **Assets:** |  |  |  |  |
|  <u><u>Investments:</u></u> |  |  |  |  |
| &nbsp;&nbsp;&nbsp; Common Stocks | $178782129 | $— | $— | $178782129 |
| &nbsp;&nbsp;&nbsp; Exchange Traded Funds | 2172690 |  |  | 2172690 |
| &nbsp;&nbsp;&nbsp; Money Market Funds | 175763 |  |  | 175763 |
|  Total Investments | $181130582 | $— | $— | $181130582 |

---

Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the Fund's investments may fluctuate from period to period. Additionally, the fair value of investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values the Fund's may ultimately realize. Further, such investments may be subject to legal and other restrictions on resale or otherwise less liquid than publicly traded securities.

**SGI** **Enhanced Market Leaders** **ETF** 

**Notes to Financial Statements (Continued)** 

**June 30, 2025 (Unaudited)**

For fair valuations using significant unobservable inputs, U.S. generally accepted accounting principles ("U.S. GAAP") requires each Fund to present a reconciliation of the beginning to ending balances for reported market values that presents changes attributable to total realized and unrealized gains or losses, purchase and sales, and transfers in and out of Level 3 during the period. Transfers in and out between levels are based on values at the end of the period. A reconciliation of Level 3 investments is presented only if a Fund had an amount of Level 3 investments at the end of the reporting period that was meaningful in relation to its net assets. The amounts and reasons for all Level 3 transfers are disclosed if a Fund had an amount of total Level 3 transfers during the reporting period that was meaningful in relation to its net assets as of the end of the reporting period.

During the current fiscal period, the Fund had no Level 3 purchases, sales, or transfers.

**DISCLOSURES ABOUT DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES** 

Derivative instruments are defined as financial instruments whose value and performance are based on the value and performance of another security or financial instrument. Derivative instruments that the Fund used during the period included options.

The following tables provide quantitative disclosures about fair value amounts of, and gains and losses on, the Fund's derivative instruments as of and for the current fiscal period.

The following table lists the fair values of the Fund's derivative holdings as of the end of the current fiscal period, grouped by contract type and risk exposure category.

The following table lists the amounts of realized gains/(losses) included in net increase/(decrease) in net assets resulting from operations during the current fiscal period.

---

| | | | |
|:---|:---|:---|:---|
| **FUND** | **DERIVATIVE TYPE** | **STATEMENT OF OPERATIONS <br> LOCATION** | **VALUE** |
| **Realized Gain (Loss)**  | **Realized Gain (Loss)**  | **Realized Gain (Loss)**  | **Realized Gain (Loss)**  |
|  SGI Enhanced Market Leaders ETF | Written Options | Net realized gain/(loss) from written options | $(182) |
|  **Total Realized Gain/(Loss)** |  |  | $(182) |

---

For financial reporting purposes, the Fund does not offset fair value amounts recognized for derivative instruments and fair value amounts recognized for the right to reclaim cash collateral (receivables) or the obligation to return cash collateral (payables) arising from derivative instruments recognized at fair value executed with the same counterparty and master netting arrangement.

**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 and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and those differences could be significant.

**INVESTMENT TRANSACTIONS, INVESTMENT INCOME AND EXPENSES** — The Fund records security transactions based on trade date for financial reporting purposes. The cost of investments sold is determined by use of the specific identification method for both financial reporting and income tax purposes in determining realized gains and losses on investments. Interest income (including amortization of premiums and accretion of discounts) is accrued when earned. Dividend income is recorded on the ex-dividend date. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The Fund's investment income, expenses (other than class specific expenses) and unrealized and realized gains and losses are allocated daily to each class of shares based upon the relative proportion of net assets of each class at the beginning of the day. Certain expenses are shared with The RBB Trust (the "Trust"), a series trust of affiliated funds. Expenses

**SGI** **Enhanced Market Leaders** **ETF** 

**Notes to Financial Statements (Continued)** 

**June 30, 2025 (Unaudited)**

incurred on behalf of a specific class, fund or fund family of the Trust or RBB are charged directly to the class, fund or fund family (in proportion to net assets). Expenses incurred for all funds (such as director or professional fees) are charged to all funds in proportion to their average net assets of the Trust and RBB, or in such other manner as the Board deems fair or equitable. Expenses and fees, including investment advisory and administration fees, are accrued daily and taken into account for the purpose of determining the NAV of the Fund.

**DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS** — Dividends from net investment income and distributions from net realized capital gains, if any, are declared and paid at least annually to shareholders and recorded on the ex-dividend date. Income dividends and capital gain distributions are determined in accordance with U.S. federal income tax regulations, which may differ from U.S. GAAP.

**U.S. TAX STATUS** — No provision is made for U.S. income taxes as it is each Fund's intention to continue to qualify for and elect the tax treatment applicable to regulated investment companies under Subchapter M of the Internal Revenue Code of 1986, as amended, and make the requisite distributions to its shareholders which will be sufficient to relieve it from U.S. income and excise taxes.

**SEC RULE 18F-4** — Effective August 19, 2022, the U.S. Securities and Exchange Commission (the "SEC") implemented Rule 18f-4 under the 1940 Act ("Rule 18f-4"), providing for the regulation of a registered investment company's use of derivatives and certain related instruments. Among other things, Rule 18f-4 limits a fund's derivatives exposure through a value-at-risk test and requires the adoption and implementation of a derivatives risk management program for certain derivatives users. The Fund, as a full derivatives user (as defined in Rule 18f-4), are subject to the full requirements of Rule 18f-4. The Fund is required to comply with Rule 18f-4 and has adopted procedures for investing in derivatives and other transactions in compliance with Rule 18f-4.

**WRITTEN OPTIONS** — The Fund may enter into options written for: bona fide hedging; attempting to offset changes in the value of securities held or expected to be acquired or be disposed of; attempting to minimize fluctuations in foreign currencies; attempting to gain exposure to a particular market, index or instrument; or other risk management purposes. Such options may relate to particular securities or domestic stock indices and may or may not be listed on exchanges regulated by the Commodity Futures Trading Commission or on other non-U.S. exchanges. An option on a futures contract gives the purchaser the right, in return for the premium paid, to assume a position in the contract (a long position if the option is a call and a short position if the option is a put) at a specified exercise price at any time during the option exercise period. The writer of the option is required upon exercise to assume a short futures position (if the option is a call) or a long futures position (if the option is a put). Upon exercise of the option, the accumulated cash balance in the writer's futures margin account is delivered to the holder of the option. That balance represents the amount by which the market price of the futures contract at exercise exceeds, in the case of a call, or is less than, in the case of a put, the exercise price of the option. The maximum risk of loss associated with writing put options is limited to the exercised fair value of the option contract. The maximum risk of loss associated with writing call options is potentially unlimited. The Fund also has the additional risk of being unable to enter into a closing transaction at an acceptable price if a liquid secondary market does not exist. The Fund also may write OTC options where completing the obligation depends upon the credit standing of the other party. Option contracts also involve the risk that they may result in loss due to unanticipated developments in market conditions or other causes. Written options are initially recorded as liabilities to the extent of premiums received and subsequently marked to market to reflect the current value of the option written. Gains or losses are realized when the option transaction expires or closes. When an option is exercised, the proceeds on sales for a written call option or the purchase cost for a written put option is adjusted by the amount of the premium received. Listed option contracts present minimal counterparty credit risk since they are exchange traded and the exchange's clearinghouse, as counterparty to all exchange-traded options, guarantees the options against default. As of the end of the reporting period, all of the Fund's written options are exchange-traded options.

**CASH AND CASH EQUIVALENTS** — Cash and cash equivalents are valued at cost plus accrued interest, which approximates market value.

**SGI** **Enhanced Market Leaders** **ETF** 

**Notes to Financial Statements (Continued)** 

**June 30, 2025 (Unaudited)**

**OTHER** — In the normal course of business, the Fund may enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is dependent on claims that may be made against the Fund in the future, and, therefore, cannot be estimated; however, the Fund expect the risk of material loss from such claims to be remote.

**2. INVESTMENT ADVISER AND OTHER SERVICES** 

Effective May 5, 2025, Summit Global Investments LLC serves as the Adviser to the Fund. SG Trading Solutions, LLC ("SG Trading Solutions" or "Sub-Adviser") serves as the investment sub-adviser to the Fund. Subject to the supervision of the Board, the Adviser manages the overall investment operations of the Fund in accordance with the Fund's respective investment objective and policies and formulates a continuing investment strategy for the Fund pursuant to the terms of the Investment Advisory Agreement between the Adviser and the Company on behalf of the Fund (the "Advisory Agreement"). The Fund compensates the Adviser with a unitary management fee for its services at an annual rate of 0.50% of the average daily net assets of the Fund. The fee is calculated daily and paid monthly in arrears. From the unitary management fee, the Adviser pays most of the expenses of the Fund, including the cost of sub-advisory fees to SG Trading Solutions, transfer agency, custody, fund administration, legal, audit and other services. However, under the Investment Advisory Agreement, the Adviser is not responsible for interest expenses, brokerage commissions and other trading expenses, taxes and other extraordinary costs such as litigation and other expenses not incurred in the ordinary course of business. The Sub-Adviser is an affiliate of the Adviser. The Sub-Adviser implements rigorous quantitative and fundamental analysis to achieve best execution, and is subject to oversight by the Adviser and the Board. Under the Sub-Advisory Agreement, the Sub-Adviser receives a fee from the Adviser, calculated daily and paid monthly, equal to 0.05% of the average daily net assets of the Fund.

Prior to May 5, 2025, pursuant to an investment advisory agreement with Mitchell Sinkler &, Inc. ("MS&S") on behalf of the Managing General Partners of the Predecessor Fund (the "Prior Advisory Agreement"), the Predecessor Fund compensated MS&S at an annual rate of 0.10% of the average daily net assets of the Predecessor Fund.

U.S. Bancorp Fund Services, LLC, doing business as U.S. Bank Global Fund Services ("Fund Services"), serves as administrator for the Fund. For providing administrative and accounting services, Fund Services is entitled to receive a monthly fee, subject to certain minimum and out of pocket expenses.

Fund Services serves as the Fund's transfer and dividend disbursing agent. For providing transfer agent services, Fund Services is entitled to receive a monthly fee, subject to certain minimum and out of pocket expenses.

U.S. Bank, N.A. (the "Custodian") provides certain custodial services to the Fund. The Custodian is entitled to receive a monthly fee, subject to certain minimum and out of pocket expenses.

Quasar Distributors, LLC (the "Distributor"), a wholly-owned broker-dealer subsidiary of Foreside Financial Group, LLC, serves as the principal underwriter and distributor of the Fund's shares pursuant to a Distribution Agreement with RBB.

Effective May 5, 2025, under the Fund's unitary fee, the Adviser compensates Fund Services and the Custodian for services provided.

**3. PURCHASES AND SALES OF INVESTMENT SECURITIES** 

There were no purchases and sales of investment securities (excluding short-term obligations and redemptions in-kind) for the period ended June 30, 2025.

**SGI** **Enhanced Market Leaders** **ETF** 

**Notes to Financial Statements (Continued)** 

**June 30, 2025 (Unaudited)**

**4. SHARE TRANSACTIONS** 

Shares of the Fund are listed and traded on the NASDAQ, Inc. Market prices for the shares may be different from their NAV. The Fund issues and redeems shares on a continuous basis at NAV only in blocks of 5,000 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 certain financial institutions ("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 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 $300, payable to the Custodian. In addition, a variable fee may be charged on all cash transactions or substitutes for Creation Units of up to a maximum of 2% as a percentage of the value of the Creation Units subject to such transaction. Variable fees are imposed to compensate the Fund for the transaction costs associated with the cash transactions. Variable fees received by the Fund, if any, are displayed 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 $0.001 par value per share. Shares of the Fund have equal rights and privileges.

Effective May 5, 2025, the Fund underwent a 40 for 1 share split. The effect of the share split transaction was to multiply the number of outstanding shares of the Fund by a split factor of 40:1, with a corresponding decrease in net asset value (NAV) per share. This event does not impact the overall net assets of each class. The per share data presented in the Financial Highlights have been retroactively adjusted to reflect this share split.

**5. INDEMNIFICATIONS** 

In the ordinary course of business, the Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is dependent on claims that may be made against the Fund in the future, and therefore, cannot be estimated. However, based on experience, the risk of material loss for such claims is considered remote.

**6. FEDERAL INCOME TAX INFORMATION** 

The Fund intends to comply with the requirements of the Internal Revenue Code necessary to qualify as a regulated investment company and, as such, will not be subject to federal income taxes on otherwise taxable income which is distributed to shareholders. The Fund currently intends to retain all of its net long-term capital gains and pay the income tax at the applicable corporate income tax rate. The Fund may change this policy at any time and distribute up to all of its net long-term gains to shareholders.

For the years 2023 and 2024, the Fund did not distribute net long-term capital gains, and did not retain any gains. As such, the Fund did not pay any tax at the corporate income tax rate.

During the year ended December 31, 2024, the Fund utilized no capital loss carryover from prior years and has no capital loss carryover as of December 31, 2024.

**June 30, 2025 (Unaudited)**

Management has analyzed the Fund's tax positions taken on federal income tax returns for all open tax years (December 31, 2021–2024) and has concluded that no provision for federal income tax is required in the Fund's financial statements, except as noted above. The Fund's federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

On December 31, 2024, distributable earnings were decreased by $7,497,536 and additional paid in capital was increased by $7,497,536 due to permanent book and tax treatment of realized gains and losses attributable to redemptions in kind and differences in book and tax cost of securities. Net Assets of the Fund were unaffected by this change.

Net investment income and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. The primary difference applicable to the Fund's distributions is the requirement to pass through 40% of its aggregate expenses to the partners of the Fund. This is required because the Fund has fewer than 500 partners and does not continuously offer shares. The partners have treated this pass-through of expenses as a distribution of net investment income and a corresponding miscellaneous itemized deduction of investment expense, however, in tax years 2019 through 2025, as a result of the Tax Cuts and Jobs Act of 2017, the investment expenses are no longer deductible.

The tax character of distributions paid during 2024 and 2023 were as follows:

---

| | | |
|:---|:---|:---|
|  | **2024** | **2023** |
|  Ordinary income  | $2208778 | $2454366 |
|  Return of capital  | $27206 | $— |
|  Distributed to partners  | $2235984 | $2454366 |

---

For federal income tax purposes, distributions of net investment income and short-term capital gains are treated as ordinary income dividends.

**Approval of Agreements and Other Actions in Connection with the Approval of the New SGI Enhanced Market Leaders ETF** 

As required by the 1940 Act, the Board, including all of the Directors who are not "interested persons" of the Company, as that term is defined in the 1940 Act (the "Independent Directors"), considered the approval of (i) a new Investment Advisory Agreement (the "Investment Advisory Agreement") by and between Summit Global Investments, LLC ("SGI") and the Company, on behalf of the new SGI Enhanced Market Leaders ETF (the "Fund"), and (ii) a new investment sub-advisory agreement (the "Sub-Advisory Agreement") between SGI and SG Trading Solutions, LLC ("SGTS"), on behalf of the Fund at a meeting held on September 11-12, 2024 (the "Meeting"). At the Meeting, the Board, including all of the Independent Directors, approved the Investment Advisory Agreement and the Sub-Advisory Agreement for an initial period ending August 16, 2026. The Board's decision to approve the Investment Advisory Agreement and the Sub-Advisory Agreement reflects the exercise of its business judgment. In approving the Investment Advisory Agreement and the Sub-Advisory Agreement, the Board considered information provided by SGI and SGTS, with the assistance and advice of counsel to the Independent Directors and the Company.

In considering the approval of the Investment Advisory Agreement between the Company and SGI with respect to the Funds, and the Sub-Advisory Agreement among the Company, SGI and SGTS with respect to the Fund, the Directors took into account all materials provided prior to and during the Meeting and at other meetings throughout the past year, the presentations made during the Meeting, and the discussions held during the Meeting. The Directors reviewed these materials with management of SGI and discussed the Investment Advisory Agreement and Sub-Advisory Agreement with counsel in executive sessions, at which no representatives of SGI or SGTS were present. The Directors considered whether approval of the Investment Advisory Agreement and Sub-Advisory Agreement would be in the best interests of the Fund and its shareholders and the overall fairness of the Investment Advisory Agreement and Sub-Advisory Agreement. Among other things, the Directors considered (i) the nature, extent, and quality of services to be provided to the Fund by SGI and SGTS; (ii) descriptions of the experience and qualifications of the personnel providing those services; (iii) SGI's and SGTS's investment philosophies and processes; (iv) SGI's and SGTS's assets under management and client descriptions; (v) SGI's and SGTS's soft dollar commission and trade allocation policies, as applicable; (vi) SGI's and SGTS's advisory fee arrangements with the Company and other similarly managed clients, as applicable; (vii) SGI's and SGTS's compliance procedures; (viii) SGI's and SGTS's financial information and insurance coverage; (ix) SGI's profitability analysis relating to its proposed provision of services to the Fund; and (x) the extent to which economies of scale are relevant to the Fund. The Directors noted that the Fund had not yet commenced operations and, consequently, there was no performance information to review with respect to the Fund.

**SGI** **Enhanced Market Leaders** **ETF** 

**Other Information (Unaudited) (Concluded)**

As part of their review, the Directors considered the nature, extent and quality of the services to be provided by SGI and SGTS. The Directors concluded that SGI and SGTS had sufficient resources to provide services to the Fund.

The Board also took into consideration that the advisory fee for the Fund was a "unitary fee," meaning the Fund would pay no expenses other than the advisory fee and certain other costs such as interest, brokerage and extraordinary expenses. The Board noted that SGI would be responsible for compensating the Fund's other service providers and paying other expenses of the Fund out of SGI's own fees and resources.

After reviewing the information regarding SGI's and SGTS's estimated costs, profitability and economies of scale, and after considering the services to be provided by SGI and SGTS, the Directors concluded that the investment advisory fees to be paid by the Fund to SGI and the sub-advisory fees to be paid by SGI to SGTS were fair and reasonable and that the Investment Advisory Agreement and Sub-Advisory Agreement should be approved for an initial period ending August 16, 2026.

**PROXY VOTING RESULTS** 

A special meeting of partners (the "Special Meeting") of the Chestnut Street Exchange Fund (the "Predecessor Fund") was held on April 9, 2025.

At the Special Meeting, partners of the Predecessor Fund voted on proposal 1 to approve the Agreement and Plan of Reorganization (the "Plan of Reorganization") between the Company, on behalf of the Fund, and the Predecessor Fund providing for (i) the acquisition by the Fund of all of the assets and assumption of the liabilities of the Predecessor Fund, in exchange solely for shares of the Fund; (ii) the pro rata distribution of such shares to the partners of the Predecessor Fund; and (iii) the complete liquidation and dissolution of the Predecessor Fund. At the Special Meeting, the proposal was approved by partners of the Predecessor Fund as follows:
