SHAREHOLDER LETTER

NOVEMBER 30, 2022 (UNAUDITED)

Fellow shareholders,

One Rock Fund returned -39.91% for the twelve months ended November 30, 2022. This was below all the major indices. It was a challenging 12 months. Our investments in futures, options, and selling short were profitable and benefited the portfolio, which only highlights the drastic decline of the stock investments.

Last year was largely a reverse of 2020. The Federal Reserve raised interest by historic proportions and initiated quantitative tightening, opposite of what happened two years ago. In general, those companies who benefitted most in 2020 from the government-induced lockdowns and dislocations had the worst stock performance as most nations resumed some form of normalcy. Likewise, those who struggled the most in 2020 had the strongest relative performance as travel, in-person shopping, and oil demand rebounded.

Despite the poor results, I'm pleased with many of the actions taken during the year. It could have easily been much worse. The types of companies that we typically invest in, often technology-oriented and rapidly growing, had a terrible year. You'd have to go back to the 2000-2002 bear market to find a comparable period. Many of these companies missed revenue/earnings expectations or guided down expectations for future periods. We thankfully avoided a disproportionate number of these fundamental "misses". In addition, we increased our exposure into sectors that are experiencing better business momentum such as travel, steel and industrial. And I'm thankful our non-stock holdings in futures and options made money.

The Fund, as of November 30, 2022, has over $2 million in combined realized and unrealized capital losses. This means that those losses will have to be offset with future realized capital gains before there are any further capital gain distributions. This is an inherent tax benefit for non-retirement, taxable accounts.

One Rock Fund hit its all-time high in mid-November, 2021 and sunk to its lowest level of this bear market in mid-October, 2022. The stock market provided remarkable returns following the bear markets of 2000-2002 and 2007-2009. Unless the Lord returns, I would expect the same following this challenging period. Regardless of when it happens, there are many very attractive investment opportunities in the market currently which I would expect will provide strong returns for someone with a long-term investment outlook.

Thank you to all shareholders for your patience during a tough year and I especially thank the Lord Jesus for his wonderful blessings regardless of the stock market. Please continue to pray for our nation.

NOVEMBER 30, 2022

NOTE 1. ORGANIZATION

The One Rock Fund (the "Fund") is a non-diversified series of the MSS Series Trust (the "Trust") and commenced operations on March 6, 2020. The Trust is an open-end investment company registered under the Investment Company Act of 1940, as amended (the "1940 Act"), established under the laws of Ohio by an Agreement and Declaration of Trust dated June 20, 2006 (the "Trust Agreement"). The Trust Agreement permits the Board of Trustees (the "Board" or "Trustees") to authorize and issue an unlimited number of shares, without par value, of beneficial interest of each separate series. There are currently six separate series offered by the Trust. The investment adviser to the Fund is Wrona Investment Management, LLC (the "Adviser").

The Fund's investment objective is to seek capital appreciation.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of the Fund's significant accounting policies. These policies are in conformity with accounting principles generally accepted in the United States of America ("GAAP").

As an investment company, the Fund follows the investment company accounting and reporting requirements of the Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 946, "Financial Services - Investment Companies" including FASB Accounting Standards Update ("ASU") 2013-08.

SECURITY VALUATIONS: All investments in securities are recorded at their estimated fair value, as described in Note 3.

SECURITY TRANSACTION TIMING: For financial reporting purposes, investment transactions are accounted for on the trade date on the last business day of the reporting period. Dividend income and distributions to shareholders are recognized on the ex-dividend date. Non-cash dividend income is recorded at fair market value of the securities received. Interest income is recognized on an accrual basis. The Fund uses the specific identification method in computing gain or loss on sale of investment securities. Discounts and premiums on securities purchased are accreted or amortized over the life of the respective securities using the effective interest method. Withholding taxes on foreign dividends have been provided for in accordance with the Fund's understanding of the appropriate country's rules and tax rates.

FEDERAL INCOME TAXES: The Fund makes no provision for federal income or excise tax. The Fund intends to qualify each year as a "regulated investment company" ("RIC") under subchapter M of the Internal Revenue Code of 1986, as amended, by complying with the requirements applicable to RICs and by distributing substantially all of their taxable income. The Fund also intends to distribute sufficient net investment income and net capital gains, if any, so that they will not be subject to excise tax on undistributed income and gains. If the required amount of net investment income or gains is not distributed, the Fund could incur a tax expense. Therefore, no federal income tax or excise provision is required.

The Fund recognizes the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained, assuming examination by tax authorities. Management has

Annual Report | 12

ONE ROCK FUND

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

NOVEMBER 30, 2022

analyzed the Fund's tax positions and concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions expected to be taken on the return filed for the open tax years (2020-2021) or expected to be taken in the Fund's 2022 tax return. The Fund identifies its major tax jurisdiction as U.S. federal, and 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.

The Fund recognizes interest and penalties, if any, related to unrecognized tax benefits as income tax expense in the Statement of Operations. During the year ended November 30, 2022, the Fund did not incur any interest or penalties.

SHARE 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 (the "NYSE") (generally 4:00 p.m. Eastern Time) on each day the NYSE is open. The NAV is determined by totaling the value of all portfolio securities, cash and other assets held by the Fund, and subtracting from that total all liabilities, including accrued expenses. The total net assets are divided by the total number of shares outstanding for the Fund to determine the NAV.

DISTRIBUTIONS TO SHAREHOLDERS: The Fund typically distributes substantially all of its net investment income and realized gains in the form of dividends and taxable capital gains to its shareholders. The Fund intends to distribute dividends and capital gains at least annually. Distributions to shareholders, which are determined in accordance with income tax regulations, are recorded on the ex-dividend date. The treatment for financial reporting purposes of distributions made to shareholders during the year from net investment income or net realized capital gains may differ from their ultimate treatment for federal income tax purposes. These differences are caused primarily by differences in the timing of the recognition of certain components of income, expense or realized capital gain for federal income tax purposes. Where such differences are permanent in nature, they are reclassified in the components of the net assets based on their ultimate characterization for federal income tax purposes. Any such reclassifications will have no effect on net assets, results of operations or NAV per share of the Fund.

NON-DIVERSIFICATION RISK: As a non-diversified fund, the Fund may invest more than 5% of its total assets in the securities of one or more issuers. The Fund's performance may be more sensitive to any single economic, business, political or regulatory occurrence than the value of shares of a diversified investment company. The Fund's performance may be affected disproportionately by the performance of relatively few stocks. In addition, the volatility of the Fund may be greater than the overall volatility of the market.

EXPENSES: Expenses incurred by the Trust that do not relate to a specific fund of the Trust will be allocated to the individual funds based on each fund's relative net assets or another appropriate basis (as determined by the Trustees).

USE OF ESTIMATES: The preparation of financial statements in conformity with 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 increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS: The Fund maintains its cash in an account at a custodian bank which, at times, may exceed federally insured limits. The Fund has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk on its cash deposits.

NOTE 3. SECURITY VALUATIONS

Processes and Structure

The Board has adopted guidelines for valuing securities including circumstances in which market quotes are not readily available and has delegated to the Adviser the responsibility for determining fair value prices, subject to oversight by the Board.

Fair Value Pricing Policy

The Board has adopted guidelines for fair value pricing and has delegated to the Adviser the responsibility for determining fair value prices, subject to oversight by the Board. If market quotations are not readily available, the security will be valued at fair value (the amount which the owner might reasonably expect to receive for the security upon its current sale) as determined in good faith by the Adviser ("Fair Value Pricing"), subject to oversight by the Board. The Adviser must use reasonable diligence in determining whether market quotations are readily available. If, for example, the Adviser determines that one source of market value is unreliable, the Adviser must diligently seek market quotations from other sources, such as other brokers or pricing services, before concluding that market quotations are not available. Fair Value Pricing is not permitted when market quotations are readily available.

Fixed income securities generally are valued using market quotations provided by a pricing service. If the Adviser decides that a price provided by the pricing service does not accurately reflect the fair market value of the securities, when prices are not readily available from a pricing service, or when restricted or illiquid securities are being valued, securities are valued at fair value as determined in good faith by the Adviser, in conformity with guidelines adopted by and subject to oversight of the Board.

Short term investments in fixed income securities with maturities of less than 60 days when acquired, or which subsequently are within 60 days of maturity, may be valued by using the amortized cost method of valuation, when the Board has determined that it will represent fair value.

Financial Futures Contracts - The Fund may invest in financial and stock futures contracts. Upon entering into a financial futures contract, the Fund is required to pledge to the broker an amount of cash, U.S. government securities, or other assets, equal to a certain percentage of the contract amount (initial margin deposit). The contracts are marked-to-market daily and the resulting changes in value are accounted for as unrealized gains and losses. Subsequent payments, known as "variation margin," are made or received by the Fund each day, depending on the daily fluctuations in the fair value of the underlying security. The Fund recognizes a gain or loss equal to the daily variation margin. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the amount invested in the contract. Should market conditions move unexpectedly, the Fund may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. The use of futures transactions involves the risk of imperfect correlation in movements in the price of futures contracts, interest rates, and the underlying

hedged assets. Refer to the Fund's Schedule of Investments for details regarding open futures contracts as of November 30, 2022.

The Fund may buy or sell stock index futures to increase exposure to the broad equity market, hedge market exposure of an existing portfolio, or decrease overall market exposure. The Adviser may invest in stock index futures in this way to achieve a desired portfolio stock, or stock equivalent, exposure. The Fund's use of futures involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) leverage risk (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the futures contract may not correlate perfectly with the underlying index. Investments in futures involve leverage, which means a small percentage of assets invested in futures can have a disproportionately large impact on the Fund. This risk could cause the Fund to lose more than the principal amount invested. Futures contracts may become mispriced or improperly valued when compared to the adviser's expectation and may not produce the desired investment results. Additionally, changes in the value of futures contracts may not track or correlate perfectly with the underlying index because of temporary, or even long-term, supply and demand imbalances and because futures do not pay dividends unlike the stocks upon which they are based.

The Fund also invests in short-term opportunities through the trading of common stocks and/or stock index futures in situations that the Adviser believes to be a market overreaction to recently disclosed public news. Such situations can be caused for many reasons including earnings reports, analyst rating changes, competitor changes in business outlook, secondary stock offerings, industry headline news, extraordinary events, economic reports or monetary actions. In these circumstances, business momentum may not be a factor and the expectation is for a short-term trade.

Options - When the Fund writes an option, an amount equal to the premium received by the Fund is recorded as a liability and is subsequently adjusted to the current fair value of the option written. Premiums received from writing options that expire unexercised are treated by the Fund on the expiration date as realized gains from investments. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or, if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security or currency in determining whether the Fund has realized a gain or loss. If a put option is exercised, the premium reduces the cost basis of the securities purchased by the Fund. The Fund as writer of an option bears the market risk of an unfavorable change in the price of the security underlying the written option. See Note 4 for additional disclosure on the Fund's options transactions during the period.

Short Sales of Investments - The Fund may make short sales of investments, which are transactions in which a Fund sells a security it does not own in anticipation of a decline in the fair value of that security. To complete such a transaction, the Fund must borrow the security to make delivery to the buyer. The Fund is then obligated to replace the security borrowed by purchasing it at the market price at the time of replacement. The broker retains the proceeds of short sales to the extent necessary to meet margin requirements until the short position is closed out.

Annual Report | 15

ONE ROCK FUND

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

NOVEMBER 30, 2022

If a security pays a dividend while the Fund holds it short, the Fund will need to pay the dividend to the original owner of the security. Since the Fund borrowed the shares and sold them to a third party, the third party will receive the dividend from the security and the Fund will pay the original owner the dividend directly. The Fund is not entitled to the dividend because it does not own the shares. A gain, limited to the price at which the Fund sold the security short, or a loss, unlimited in size, will be recognized upon the termination of a short sale.

Short sales and written options are collateralized by pledged securities held at Interactive Brokers, LLC. The collateral required is determined daily by reference to the market value of the short and written positions. The Fund is required to maintain margin cash balances at the prime broker sufficient to satisfy its short sales positions on a daily basis. Refer to the Statement of Assets and Liabilities for amounts due to/from broker.

Fair Value Measurements

GAAP defines fair value as the price that the Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date and also establishes a framework for measuring fair value, and a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability. The three-tier hierarchy seeks to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. 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 are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the Fund's own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.

Equity securities (common stocks). Securities traded on a national securities exchange (or reported on the NASDAQ national market) are stated at the last reported sales price on the day of valuation. To the extent these securities are actively traded, and valuation adjustments are not applied, they are categorized in Level 1 of the fair value hierarchy. Certain foreign securities may be fair valued using a pricing service that considers the correlation of the trading patterns of the foreign security to the intraday trading in the U.S. markets for investments such as American Depositary Receipts, financial futures, exchange traded funds, and the movement of the certain indexes of securities based on a statistical analysis of the historical relationship and that are categorized in Level 2. Preferred stock and other equities traded on inactive markets or valued by reference to similar instruments are also categorized in Level 2.

Short-term investments. Short term investments are valued using amortized cost, which approximates fair value. These securities will be categorized in Level 1 of the fair value hierarchy.

Derivative instruments (future contracts and options). Listed derivative instruments that are actively traded, including futures contracts, are valued based on quoted prices from the exchange and are categorized in Level 1 of the fair value hierarchy. Options are valued at the

ONE ROCK FUND

last sales prices on the valuation date if the last sales price is between the closing bid and asked prices. Otherwise, options are valued at the closing bid price. These securities will be categorized in Level 2 of the fair value hierarchy if valued at other than closing price.

A description of the valuation techniques applied to the Fund's major categories of assets and liabilities and other financial instruments measured at fair value on a recurring basis follows.

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

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

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

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

The following table presents information about the Fund's investments measured at fair value as of November 30, 2022, by major security type:

* Industry classifications of these categories are detailed on the Fund's Schedule of Investments.

NOTE 4. DERIVATIVE TRANSACTIONS

The effect of derivative instruments on the Statements of Operations for the year ended November 30, 2022, and related activity was as follows:

The Fund considers the average quarter-end notional amounts during the period, categorized by primary underlying risk, to be representative of its derivative activities during the year ended November 30, 2022.

The Adviser consistently assesses the value of existing positions in the Fund. Generally, the Adviser exercises patience when fundamentals are stable but prices are volatile. The Adviser may at times write covered call options on a small portion of existing common stock positions in the Fund to generate premium. The Fund may trade financial instruments where they are considered to be a seller of credit derivatives in accordance with authoritative guidance under GAAP on derivatives and hedging. The Fund may purchase and write (i.e., sell) put and call options. Such options may relate to particular securities or stock indices, and may or may not be listed on a domestic or foreign securities exchange and may or may not be issued by Interactive Brokers, LLC. Option trading is a highly specialized activity that entails greater than ordinary investment risk. Options may be more volatile than the underlying instruments, and therefore, on a percentage basis, an investment in options may be subject to greater fluctuation than an investment in the underlying instruments themselves.

A call option for a particular security gives the purchaser of the option the right to buy, and the writer (seller) the obligation to sell, the underlying security at the stated exercise price at any time prior to the expiration of the option, regardless of the market price of the security. The premium paid to the writer is in consideration for undertaking the obligation under the option contract. A put option for a particular security gives the purchaser the right to sell the security at the stated exercise price at any time prior to the expiration date of the option, regardless of

The Fund may buy or sell stock index futures to increase exposure to the broad equity market, hedge market exposure of an existing portfolio, or decrease overall market exposure. The Adviser may invest in stock index futures in this way to achieve a desired portfolio stock, or stock equivalent, exposure.

NOTE 5. RELATED PARTY TRANSACTIONS

Pursuant to a management agreement (the "Management Agreement"), the Fund pays the Adviser, an investment advisory fee, computed and accrued daily and paid monthly, at an annual rate of 1.00% of the Fund's average daily net assets. The Adviser has contractually agreed to reduce its fees and to reimburse expenses, at least through December 31, 2024 to ensure that total annual Fund operating expenses after fee waiver and reimbursement (acquired fund fees and expenses, interest expenses, dividend expenses on short sales, taxes, brokerage commissions, expenses incurred in connection with any merger or reorganization, or extraordinary expenses such as litigation) will not exceed 1.75% for shares of the average daily net assets. The fee waiver and expense reimbursement is subject to possible recoupment from the Fund within three years after the date on which the waiver or reimbursement occurs, if such recoupment can be achieved within the lesser of the foregoing expense limit or the expense limits in place at the time of recoupment.

This reclassification has no impact on the net asset value of the Fund and is designed generally to present undistributed income and net realized gains on a tax basis, which is considered to be more informative to shareholders.

Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States.

The tax character of distributions paid during the years ended November 30, 2022, and 2021 were as follows:

NOTE 9. CONTINGENCIES AND COMMITMENTS

The Fund indemnifies the Trust's officers and Trustees for certain liabilities that might arise from their performance of their duties to the Fund. Additionally, in the normal course of business the Fund enters into contracts that contain a variety of representations and warranties and which provide 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 that have not yet occurred. However, based on experience, the Fund expects the risk of loss to be remote.

10. MARKET AND GEOPOLITICAL RISK

The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund may

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

NOVEMBER 30, 2022

underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years, such as terrorist attacks around the world, natural disasters, social and political discord or debt crises and downgrades, among others, may result in market volatility and may have long term effects on both the U.S. and global financial markets. It is difficult to predict when similar events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund. The novel coronavirus (COVID-19) global pandemic and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, as well as the forced or voluntary closure of, or operational changes to, many retail and other businesses, had negative impacts, and in many cases severe negative impacts, on markets worldwide. It is not known how long such impacts, or any future impacts of other significant events described above, will or would last, but there could be a prolonged period of global economic slowdown, which may impact your investment. Therefore, the Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates can have the same impact on all types of securities and instruments. In times of severe market disruptions, you could lose your entire investment.

NOTE 11. SECTOR CONCENTRATION RISK

Sector concentration risk is the possibility that securities within the same sector will decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund's share price may fluctuate more widely than the value of the shares of a mutual fund that invests in a broader range of sectors. Additionally, some sectors could be subject to greater government regulation than other sectors. Therefore, changes in regulatory policies for those sectors may have a material effect on the value of securities issued by companies in those sectors.

As of November 30, 2022, the Fund had 62.09% of its investments invested in the technology sector. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

NOTE 12. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Fund through the issuance date of these financial statements and has noted no additional events requiring accounting or disclosure.

a series of MSS Series Trust

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of the One Rock Fund (the "Fund"), a series of MSS Series Trust, including the schedule of investments and schedule of written options as of November 30, 2022, the related statement 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 related notes (collectively referred to as the "financial statements"), and the financial highlights the period March 6, 2020 (commencement of investment operations) through November 30, 2020 and for each of the two years in the period ended November 30, 2022. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the One Rock Fund, a series of MSS Series Trust, as of November 30, 2022, the results of its operations for the year then ended, the changes in net assets for each of the two years in the period then ended and the financial highlights for the period March 6, 2020 (commencement of investment operations) through November 30, 2020 and for each of the two years in the period ended November 30, 2022, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. 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 Fund in accordance with 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 Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, 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 Fund's internal control over financial reporting. Accordingly, we express no such opinion.

Our audit 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 procedures included confirmation of securities and cash owned as of November 30, 2022, by correspondence with the custodian and brokers. 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. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more of the

EXPENSE ILLUSTRATION

NOVEMBER 30, 2022 (UNAUDITED)

Expense Example

As a shareholder of the Fund, you incur ongoing costs which consist of, management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the six-month period and held for the entire period, June 1, 2022 through November 30, 2022.

Actual Expenses

The first line of the table below 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 paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During the Period" to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table below provides information about hypothetical account values and hypothetical expenses based on each Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in each Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

INVESTMENT ADVISORY AGREEMENT RENEWAL

At its meeting held on September 21, 2022, Legal Counsel directed the Trustees attention to the renewal of the investment advisory agreement between Wrona and the Trust, on behalf of One Rock (the "One Rock Management Agreement").

Nature, Extent and Quality of Service. The Trustees noted the experience of the personnel responsible for servicing the Fund, noting that the Adviser continued to serve as the president, portfolio manager, and chief compliance officer. They reviewed the Adviser's compliance practices, including its daily checks and interactions with the Fund's CCO. Counsel noted that the adviser did not report any litigations or regulatory examinations. After a discussion, the Trustees agreed that the services provided by the Adviser have been satisfactory.

Performance. The Trustees next considered the performance of the One Rock Fund. They noted that the One Rock Fund had underperformed the S&P 500 Index, but had outperformed its peer group and the Morningstar Category Average for the one-year period ended July 31, 2022, while underperforming the peer group average for the same time period. The Trustees further examined the Fund's performance, noting that it outperformed the S&P 500 Index and the peer group average since inception. After further discussion, the Trustees agreed that performance was not unsatisfactory.

Fees and Expenses. The Trustees noted that the Fund's advisory fee is 1.00% and observed that the Fund's advisory fee was lower than the Fund's peer group average. Counsel indicated that Wrona had agreed to an expense limitation agreement, whereby the Adviser agreed to limit the Fund's expenses to 1.75% until December 31, 2024. After a further discussion, the Trustees agreed that the advisory fee was not unreasonable.

Profitability. The Trustees reviewed Wrona's profitability analysis with respect to the Fund during the past 12 months of operations. The Trustees noted that Wrona earned a profit during that period. After a discussion, the Trustees determined the Adviser's profitability with respect to its management of the Fund was not excessive.

Economies of Scale. The Trustees considered whether the Fund would experience economies of scale at a certain asset level. Counsel stated for the benefit of the Trustees that the Adviser indicated that it would be open to discussing the implementation of economies of scale as assets increased. The Trustees concluded that the absence of breakpoints at this time was reasonable.

Conclusion. Having requested and received such information from the Adviser as the Trustees believed reasonably necessary to evaluate the terms of One Rock Management Agreement, and as assisted by the advice of counsel, the Trustees concluded that the fee structure was reasonable, and that approval of the One Rock Management Agreement was in the best interests of the shareholders of the One Rock Fund.
