**INVESTMENT OBJECTIVE**

The Optimal Tax Managed Equity ETF (the "Fund") seeks to achieve long-term capital appreciation.

**FEES AND EXPENSES**

This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund ("Shares"). **You may also pay brokerage commissions on the purchase and sale of Shares, which are not reflected in the table or example.**

---

| | |
|:---|:---|
| **Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)** | **Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)** |
| Management Fee | 0.49% |
| Distribution and/or Service (12b-1) Fees |  |
| Other Expenses<sup>1</sup> | 0.00% |
| **Total Annual Fund Operating Expenses** | **0.49%** |

---

<sup>1</sup> Estimated for the current fiscal year.

**EXAMPLE**

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 for the time periods indicated and then hold or sell all of your Shares at the end of those periods. The example also assumes that the Fund provides a return of 5% a year and that operating expenses remain the same. You may also pay brokerage commissions on the purchase and sale of Shares, which are not reflected in the example. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

| **One Year:** | **Three Years:** |
| $50 | $157 |

**PORTFOLIO TURNOVER**

The Fund may pay transaction costs, including commissions when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. As of the date of this Prospectus, the Fund has not yet commenced operations and portfolio turnover data therefore is not available.

**PRINCIPAL INVESTMENT STRATEGIES**

The Fund is an actively-managed exchange-traded fund ("ETF") that principally invests in the U.S.-listed equity securities of profitable large-, mid-, and small-capitalization companies based on a proprietary model developed by the Fund's sub-adviser, Optimal Tax Asset Management, Inc. (the "Sub-Adviser").

------

The Sub-Adviser's model screens for companies that demonstrate profitability through one of two pathways:

---

| | |
|:---|:---|
| *GAAP Profitability:* | For companies in any sector, inclusion is permitted if the company has (i) trailing twelve-month net income greater than zero and (ii) most-recent-quarter net income greater than zero. |
| *Rule of 40 Bypass:* | For high-growth technology, healthcare, and communications services companies that have not yet achieved GAAP profitability, inclusion is permitted if a company demonstrates (i) a "Rule of 40" score (Revenue Growth % + Free Cash Flow Margin %) of 40% or higher for two or more consecutive quarters, (ii) a gross margin of 50% or higher, and (iii) revenue growth that is stable or accelerating quarter-over-quarter. |

---

After applying the model screens (i.e., dual-path qualification system) to identify profitable companies, the Fund expects to allocate capital across the following three sleeves of U.S. equity exposure:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Mega-Cap Core Beta:** The Sub-Adviser expects to invest more than 50% of the Fund's net assets in approximately 200 companies that are within the top 70% of the most profitable U.S.-listed mega-capitalization companies. These companies are among the largest in the United States and generally have a market capitalization in excess of $25 billion. Companies in this sleeve will generally employ a float-adjusted market capitalization weighting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Large/Mid Cap Momentum:** A portion of the Fund's net assets will be invested in approximately 80 large- or mid-capitalization companies that are demonstrating price momentum. These companies generally have a market capitalization greater than $2 billion and less than the market capitalizations of the mega-capitalization companies described above. This sleeve targets companies in their acceleration phase using risk-adjusted 12-month price momentum (excluding the most recent month to avoid short-term reversal effects), with volatility screening to exclude the most volatile names.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **SMID-Cap Quality:** A portion of the Fund's net assets will be invested in approximately 100 small- or mid-capitalization companies that satisfy an additional quality screen. The quality screening process first excludes the bottom 20% of the GAAP profitable small-cap companies based on analyses of their operating profitability relative to their peers and the difference in returns between companies that are conservative in their capital investments (e.g., those with lower asset growth and disciplined capital spending) and those that are aggressive (e.g., those with rapid asset expansion, elevated capital expenditures, or acquisition-driven growth). The remaining companies are further screened to identify the highest-quality companies based on their cash-based profitability metrics (which are harder to manipulate than accounting earnings), conservative accruals, and conservative asset growth. Financial sector companies are excluded from this sleeve.

In addition to the U.S. equity exposure sleeves described above, the Fund may also maintain the following non-U.S. equity exposure:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Non-U.S. Equity Component:** The Fund may allocate a smaller portion of its assets (typically less than 10%) to investments with exposure to non-U.S. companies. Such exposure will generally be accomplished through investments in other ETFs and may include exposure to companies in both developed and emerging markets.

At times, the Fund may also invest in mega-, large-, or mid-capitalization companies that have recently completed an initial public offering ("IPO").

The percentage and number of securities allocated to each sleeve, as noted above, may vary over time depending on market conditions. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities.

Although the Fund will not concentrate its investments in a particular industry, the Sub-Adviser anticipates that the Fund's investment process for individual stock selection may lead to the portfolio being focused on a small number of sectors. These sectors will likely be different over time, as the economic and market environment changes. The Fund is non-diversified and therefore may invest a larger percentage of its assets in the securities of a single company than diversified funds.

**PRINCIPAL INVESTMENT RISKS**

An investment in the Fund involves risk, including those described below. *There is no assurance that the Fund will achieve its investment objective*. An investor may lose money by investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any government agency. More complete risk descriptions are set forth below under the heading "*Additional Information About the Fund's Principal Investment Risks.*"

**Mega- and Large-Capitalization Stock Risk.** Mega- and large-capitalization stocks may trail the returns of the overall stock market. Mega- and large-capitalization stocks tend to go through cycles of doing better — or worse — than the stock market in general. These periods have, in the past, lasted for as long as several years.

------

**Mid-Capitalization Companies Risk.** Investing in securities of mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies. Often mid-capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions.

**Small-Capitalization Companies Risk.** Investing in securities of small-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. Small-capitalization companies often have less predictable earnings, more limited product lines, markets, distribution channels and financial resources, and the management of such companies may be dependent upon one or few people. Price movements of small-capitalization companies may be more volatile than mid-capitalization and large-capitalization companies.

**Investment Risk.** When you sell your Shares, they could be worth less than what you paid for them. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular asset classes or industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security. Geopolitical and other risks, including war, terrorism, trade disputes, political or economic dysfunction within some nations, public health crises, and environmental disasters such as earthquakes, fire, and floods, may add to instability in world economies and volatility in markets generally. Changes in trade policies and international trade agreements could affect the economies of many countries in unpredictable ways. The value of a security may also decline due to factors that affect a particular industry or group of industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected. Therefore, you may lose money by investing in the Fund.

**Asset Allocation Risk.** The Fund is also subject to asset allocation risk, which is the chance that the selection of investments, and the allocation of assets to such investments, will cause the Fund to underperform other funds with a similar investment objective.

**Non-Diversification Risk.** Because the Fund is non-diversified, it may be more sensitive to economic, business, political or other changes affecting individual issuers or investments than a diversified fund, which may result in greater fluctuation in the value of the Shares and greater risk of loss.

**Equity Investing Risk.** An investment in the Fund involves risks similar to those of investing in any fund holding equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices. The values of equity securities could decline generally or could underperform other investments. In addition, securities may decline in value due to factors affecting a specific issuer, market or securities markets generally.

**Growth Stock Investment Risk**. Growth-oriented common stocks may involve larger price swings and greater potential for loss than other types of investments. Growth stocks tend to trade at a premium when analyzed using traditional valuation metrics such as price-to-earnings ratio and price-to-book ratio. Due to this premium valuation, growth stocks tend to be more susceptible to big price swings. In bull markets, they tend to rise at a much faster pace than the overall market, and they tend to decline at a more rapid rate in bear markets.

**Quality Stocks Risk.** Stocks included in the Fund are deemed by the Sub-Adviser to be quality stocks, but there is no guarantee that the past performance of these stocks will continue. Companies that issue these stocks may experience a decline in value, as well as increased leverage, resulting in lower than expected or negative returns to Fund shareholders. Many factors can affect a stock's quality and performance, and the impact of these factors on a stock or its price can be difficult to predict.

**Quantitative Security Selection Risk.** Data for some companies may be less available and/or less current than data for companies in other markets. The Sub-Adviser uses quantitative models, and its processes could be adversely affected if erroneous or outdated data is utilized. In addition, securities selected using a quantitative model could perform differently from the financial markets as a whole as a result of the characteristics used in the analysis, the weight placed on each characteristic and changes in the characteristic's historical trends.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Profitability Screen Risk.* The Fund's universal profitability requirement will exclude unprofitable companies that may subsequently appreciate significantly. Some transformational companies operate at a loss during growth phases; while the Rule of 40 bypass addresses this for eligible technology, healthcare, and communications services companies, unprofitable companies in other sectors will be excluded regardless of growth potential.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Rule of 40 Risk.* The Rule of 40 bypass relies on metrics (revenue growth and free cash flow margin) that may not accurately predict future profitability or business sustainability. Companies qualifying via Rule of 40 may never achieve GAAP profitability.

------

**ETF Risks.**

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** *Premium-Discount Risk.* The Shares may trade above or below their net asset value ("NAV"). The market prices of Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on New York Stock Exchange (the "Exchange") or other securities exchanges. The trading price of Shares may deviate significantly from NAV during periods of market volatility or limited trading activity in Shares. In addition, you may incur the cost of the "spread," that is, any difference between the bid price and the ask price of the Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Cost of Trading Risk.* Investors buying or selling Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Trading Risk.* Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of its underlying portfolio holdings, which can be less liquid than Shares, potentially causing the market price of Shares to deviate from its NAV. The spread varies over time for Shares of the Fund based on the Fund's trading volume and market liquidity and is generally lower if the Fund has high trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity (which is often the case for funds that are newly launched or small in size).

**Risk of Investing in Other ETFs.** Because the Fund may invest in other ETFs, the Fund's investment performance is impacted by the investment performance of the selected underlying ETFs. An investment in the Fund is subject to the risks associated with the ETFs that then-currently comprise the Fund's portfolio. At times, certain of the segments of the market represented by the Fund's underlying ETFs may be out of favor and underperform other segments. The Fund will indirectly pay a proportional share of the expenses of the underlying ETFs in which it invests (including operating expenses and management fees).

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

**Momentum Investing Risk**. The Fund may pursue momentum and trend following strategies that seek to identify securities that have had higher recent price performance compared to other securities. These securities may be more volatile than a broad cross-section of securities. High momentum may also be a sign that the securities' prices have peaked. Momentum can turn quickly and cause significant variation from other types of investments. The Fund may experience significant losses if momentum stops, turns or otherwise behaves differently than predicted.

**Management Risk.** The Fund is actively-managed and may not meet its investment objective based on the Adviser's, Sub-Adviser's, or portfolio manager's success or failure to implement investment strategies for the Fund. The success of the Fund's investment program depends largely on the investment techniques and risk analyses applied by the Adviser, Sub-Adviser, and the portfolio manager and the skill of the Adviser, Sub-Adviser, and/or portfolio manager in evaluating, selecting, and monitoring the Fund's assets. The Fund could experience losses (realized and unrealized) if the judgment of the Adviser, Sub-Adviser, or portfolio manager about markets or sectors or the attractiveness of particular investments made for the Fund's portfolio prove to be incorrect. It is possible the investment techniques and risk analyses employed on behalf of the Fund will not produce the desired results. Absent unusual circumstances (*e.g.*, the Adviser determines a different security has higher liquidity but offers a similar investment profile as a recommended security), the Adviser will generally follow the Sub-Adviser's investment recommendations to buy, hold, and sell securities and financial instruments.

**Foreign Investment Risk.** Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Investments in or exposures to foreign securities are subject to special risks, including risks associated with foreign securities generally, including differences in information available about issuers of securities and investor protection standards applicable in other jurisdictions; capital controls risks, including the risk of a foreign jurisdiction imposing restrictions on the ability to repatriate or transfer currency or other assets; currency risks; political, diplomatic and economic risks; regulatory risks; and foreign market and trading risks, including the costs of trading and risks of settlement in foreign jurisdictions.

------

**Periodic Reallocation Risk**. Because the Sub-Adviser will generally reallocate the Fund's portfolio on a periodic basis, generally each quarter, (i) the Fund's market exposure may be affected by significant market movements promptly following the periodic reconstitution that are not predictive of the market's performance for the subsequent period and (ii) changes to the Fund's market exposure may lag a significant change in the market's direction (up or down) by as long as a month if such changes first take effect promptly following the periodic reallocation. Such lags between market performance and changes to the Fund's exposure may result in significant underperformance relative to the broader equity or fixed income market.

**New Fund Risk.** The Fund is a recently organized investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision. There can be no assurance that the Fund will grow to or maintain an economically viable size.

**New Sub-Adviser Risk.** The Sub-Adviser is a newly-formed entity that has not previously been the adviser or sub-adviser to an ETF, which may create additional risks for the Fund.

**In-Kind Contribution Risk.** At its launch, the Fund expects to acquire a material amount of assets through one or more in-kind contributions that are intended to qualify as tax-deferred transactions governed by Section 351 of the Internal Revenue Code of 1986, as amended. If one or more of the in-kind contributions were to fail to qualify for tax-deferred treatment, then the Fund would not take a carryover tax basis in the applicable contributed assets and would not benefit from a tacked holding period in those assets. This could cause the Fund to incorrectly calculate and report to shareholders the amount of gain or loss recognized and/or the character of gain or loss (*e.g.*, as long-term or short-term) on the subsequent disposition of such assets. In addition, the failure of a contribution to satisfy the requirements of Section 351 could cause the contribution to be treated as a taxable event for the contributing shareholder at the time of contribution. If such failure is not discovered until a later time, this could also cause the contributing shareholder to incorrectly calculate and report gain or loss on the shareholder's disposition of Fund shares.

**PERFORMANCE**

Performance information is not provided below because the Fund has not yet been in operation for one full calendar year. When provided, the information will provide some indication of the risks of investing in the Fund by showing how the Fund's average annual returns compare with a broad measure of market performance. Past performance does not necessarily indicate how the Fund will perform in the future. Updated performance information will be available at https://o.tax.

**INVESTMENT ADVISER & INVESTMENT SUB-ADVISER**

Investment Adviser: Empowered Funds, LLC dba EA Advisers (the "Adviser") <br> Investment Sub-Adviser: Optimal Tax Asset Management, Inc. (the "Sub-Adviser")

**PORTFOLIO MANAGER**

Austin S. Collins is the portfolio manager and the person primarily responsible for the day-to-day management of the Fund. Mr. Collins has served as portfolio manager of the Fund since its inception.

**PURCHASE AND SALE OF SHARES** 

Individual Shares are listed on a national securities exchange and may only be purchased and sold in the secondary market through a broker-dealer at a market price. Because Shares trade at market prices rather than NAV, Shares may trade at a price greater than NAV (at a "premium") or less than NAV (at a "discount"). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying and selling Shares in the secondary market (the "bid/ask spread").

**TAX INFORMATION** 

The Fund's distributions generally are taxable to you as ordinary income, capital gain, or some combination of both, unless your investment is made through an Individual Retirement Account ("IRA") or other tax-advantaged account. However, subsequent withdrawals from such a tax-advantaged account may be subject to U.S. federal income tax. You should consult your own tax advisor about your specific tax situation.

**PURCHASES THROUGH BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES** 

If you purchase Shares through a broker-dealer or other financial intermediary, the Fund and its related companies may pay the intermediary for the sale of Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend Shares over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
