Investment Objective

The Congress Intermediate Bond ETF (the “Intermediate Bond Fund” or “Fund”) seeks to maximize total return.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Intermediate Bond Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Annual Fund Operating Expenses (Expenses that you pay each year as a percentage of the value of your investment)
Management Fees	0.35	%
Distribution and Service (12b-1) Fees	0.00	%
Other Expenses(1)	0.00	%
Total Annual Fund Operating Expenses(2)	0.35	%

(1) Under the Investment Advisory Agreement, Congress Asset Management Company, LLP (the “Adviser”) has agreed to pay all expenses of the Fund except for the fee paid to the Adviser pursuant to the Investment Advisory Agreement, interest charges on any borrowings, taxes, brokerage commissions and other expenses incurred in placing orders for the purchase and sale of securities and other investment instruments, acquired fund fees and expenses, accrued deferred tax liability, extraordinary expenses, and distribution fees and expenses paid by the Fund under any distribution plan adopted pursuant to Rule 12b-1 under the Investment Company Act of 1940, as amended (the “1940 Act”).

Example

The Example below is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% annual return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$36	$113

Portfolio Turnover

The Fund pays transaction costs, such as 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 Fund 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 the Fund has not yet commenced operations, there is no portfolio turnover information to provide at this time.

Principal Investment Strategies

The Fund is an actively-managed exchange-traded fund (“ETF”) that seeks to maximize total return.

The Fund seeks to achieve its investment objective by investing at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities and other instruments that have economic characteristics similar to such securities. The Fund principally invests in U.S.-dollar denominated, investment-grade securities and seeks to typically maintain a dollar-weighted average portfolio maturity of zero to ten years and are rated at time of issuance in the top four rating categories of a Nationally Recognized Statistical Rating Organization, or unrated and deemed to be of comparable quality by the Adviser. The Fund may invest in instruments with a range of maturities, including short-, medium- or long-term maturities. The Fund may also invest in other investment companies, including ETFs, that have a similar policy to invest in at least 80% of their net assets in similar fixed income securities and the Fund may count such holdings towards the Fund’s 80% investment policy. The Fund may invest up to 20% of its net assets in high yield (junk) securities.

The Fund seeks to typically maintain an average portfolio duration of three to five years. Duration is the weighted-average time in years for an investor to recoup the cost of an investment from the cash flows associated with a bond or portfolio of bonds. It can be used as a measure of price sensitivity to changes in yields or interest rates with a lower duration indicating less sensitivity to interest rates. For example, the price of a security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates.

The Fund may, from time to time, have significant exposure to one or more sectors of the market.

The Fund may invest in a variety of fixed income instruments with a fixed or floating (variable) interest rate. The Fund’s investments may include investment-grade U.S. corporate and government debt obligations (including securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities), as well as municipal securities issued by states, U.S. territories, and possessions, general obligation securities and revenue securities. The foregoing may include municipal lease obligations and insured municipal securities. The Fund’s investments may also include cash and cash equivalents, money market mutual funds, taxable or tax-exempt municipal securities, and shares of other ETFs that principally invest in debt securities. The Adviser may buy, hold or sell any Mortgage-Backed Security (MBS) that is explicitly or implicitly guaranteed by the US Government at the time of purchase. This includes, but is not limited to, issuers such as FNMA, GNMA and FHLMC. Additionally, the Adviser may buy, hold or sell other MBS issued by non-US Government entities as long as the security has a credit rating equal to, or greater than, that of the US Government at the time of purchase.

“Investment-grade” debt securities are those rated “Baa3” or “BBB-” or better by Moody’s Investors Service, Inc. (Moody’s) or S&P Global Ratings (S&P), each of which is a Nationally Recognized Statistical Ratings Organization. The Fund may also invest in unrated securities, in which case the Adviser may internally assign ratings to certain of those securities, after assessing their credit quality.

The Adviser may sell a security for a number of reasons including, but not limited to, if a determination is made that the security no longer meets its investment criteria or if a new security is judged more attractive than a current holding. Additionally, a bond may be sold in order to adjust duration of the overall portfolio or alter the portfolio allocation among fixed income asset classes (U.S. Treasuries, Credit, Securitized, etc.).

Principal Risks of Investing in the Intermediate Bond Fund

There is a risk that you could lose all or a portion of your investment in the Intermediate Bond Fund. The following risks are considered principal to the Intermediate Bond Fund and could affect the value of your investment in the Fund:

•Debt Securities Risks:

◦Credit Risk: The risk that an issuer of a fixed income security will fail to make interest payments or repay principal when due, in whole or in part. Changes in an issuer’s financial strength, the market’s perception of an issuer’s creditworthiness, or in a security’s credit rating may affect a security’s value. In addition, investments in sovereign debt involves a heightened risk that the issuer responsible for repayment of the debt may be unable or unwilling to pay interest and repay principal when due, and the Fund may lack recourse against the issuer in the event of default. Investments in sovereign debt are also subject to the risk that the issuer will default independently of its sovereign. Below investment grade securities (high yield/junk bonds) have speculative characteristics, and changes in economic conditions or other circumstances are more likely

to impair the ability of issuers of those securities to make principal and interest payments than is the case with issuers of investment grade securities.

◦Defaulted Securities Risk: The risk of the uncertainty of repayment of defaulted securities (e.g., a security on which a principal or interest payment is not made when due) and obligations of distressed issuers.

◦Extension Risk: The risk that if interest rates rise, repayments of principal on certain debt securities, including, but not limited to, floating rate loans and mortgage-related securities, may occur at a slower rate than expected and the expected maturity of those securities could lengthen as a result. Securities that are subject to extension risk generally have a greater potential for loss when prevailing interest rates rise, which could cause their values to fall sharply.

◦Interest Rate Risk: The risk that debt instruments will change in value because of changes in interest rates. The value of an instrument with a longer duration (whether positive or negative) will be more sensitive to changes in interest rates than a similar instrument with a shorter duration. Bonds and other debt instruments typically have a positive duration. The value of a debt instrument with positive duration will generally decline if interest rates increase. Certain other investments, such as interest-only securities and certain derivative instruments, may have a negative duration. The value of instruments with a negative duration will generally decline if interest rates decrease. Inverse floaters, interest-only and principal-only securities are especially sensitive to interest rate changes, which can affect not only their prices but can also change the income flows and repayment assumptions about those investments.

◦Prepayment Risk: The risk that the issuer of a debt security, including floating rate loans and mortgage-related securities, repays all or a portion of the principal prior to the security’s maturity. In times of declining interest rates, there is a greater likelihood that the Fund’s higher yielding securities will be pre-paid with the Fund being unable to reinvest the proceeds in an investment with as great a yield. Prepayments can therefore result in lower yields to shareholders of the Fund.

•High Yield Securities (“Junk Bond”) Risk: Investing in fixed income securities that are rated below investment grade involves risks such as increased possibility of default, decreased liquidity of the security and changes in value based on public perception of the issuer.

•Sector-Focus Risk: Investing a significant portion of the Fund’s assets in one sector of the market exposes the Fund to greater market risk and potential monetary losses than if those assets were spread among various sectors.

The remaining principal risks are presented in alphabetical order. Each risk summarized below is considered a “principal risk” of investing in the Intermediate Bond Fund, regardless of the order in which it appears.

•ETF Risks: The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:

◦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.

◦Cash Redemption Risk: The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments that cannot be broken up beyond certain minimum sizes needed for transfer and settlement). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may have less cash efficiency and pay out higher annual capital gain distributions to shareholders than if the in-kind redemption process was used. In addition, cash redemption costs could include brokerage costs or taxable gains or losses, which might not have otherwise been incurred if the redemption was fully in-kind.

3

◦Costs of Buying or Selling Shares: Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

◦Shares May Trade at Prices Other Than NAV: As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

◦Trading: Although Shares are listed for trading on NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

•Liquidity Risk: Securities purchased by the Fund may become illiquid particularly during periods of market turbulence. Illiquid investments may be more difficult to trade and value than liquid ones and, if the Fund is forced to sell these investments promptly to meet redemption requests or for other needs, the Fund may incur a loss.

•General Market Risk: Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes due to a number of factors, including: inflation (or expectations for inflation); interest rates; global demand for particular products or resources; natural disasters or events; pandemic diseases; terrorism; regulatory events; and government controls. U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors which has resulted in disruptions to business operations and supply chains, stress on the global health care system, growth concerns in the U.S. and overseas, staffing shortages and the inability to meet consumer demand, and widespread concern and uncertainty. Continuing uncertainties regarding interest rates, rising inflation, political events, rising government debt in the U.S., and trade tensions also contribute to market volatility. Conflict, loss of life and disaster connected to ongoing armed conflict between Ukraine and Russia in Europe and Israel and Hamas in the Middle East could have severe adverse effects on the region, including significant adverse affects on the regional or global economies and the markets for certain securities. The U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to market volatility and may continue to do so.

•Investments in Other Investment Companies: To the extent the Fund invests in shares of other investment companies, you will indirectly bear fees and expenses charged by those investment companies and will be subject to the risks that those investment companies are subject to. With respect to investments in other ETFs, those are also subject to the risks discussed above under “ETF Risks.”

•Management Risk: The Fund is actively-managed and may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.

•Municipal Securities Risk: Investing in various municipal securities may involve risk related to the ability of the municipalities to continue to meet their obligations for the payment of interest and principal when due. A number of municipalities have had significant financial problems recently, and these and other municipalities could, potentially, continue to experience significant financial problems resulting from lower tax revenues and/or decreased aid from state and local governments in the event of an economic downturn. This could decrease the Fund’s income or hurt the ability to preserve liquidity.

4

•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.

•U.S. Government and Agency Issuer Risk: Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Obligations of U.S. Government agencies and authorities are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. Government. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Portfolio Managers

Jeffrey Porter, CFA, Executive Vice President, Adviser; Portfolio Manager for the Fund since its inception in September 2024, and Chair of the Fixed Income Investment Policy Committee.

Purchase and Sale of Fund Shares

Shares are listed on the Exchange, and individual Shares may only be bought and sold in the secondary market through brokers at market prices, rather than NAV. Because Shares trade at market prices rather than NAV, Shares may trade at a price greater than NAV (premium) or less than NAV (discount).

The Fund issues and redeems Shares at NAV only in large blocks known as “Creation Units,” which only APs (typically, broker-dealers) may purchase or redeem. The Fund generally issues and redeems Creation Units in exchange for a portfolio of securities and/or a designated amount of U.S. cash.

Investors 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 or selling Shares in the secondary market (the “bid-ask spread”). Recent information about the Fund, including its NAV, market price, premiums and discounts, and bid-ask spreads is available on the Fund’s website at https://etfs.congressasset.com.

Tax Information

The Fund’s distributions will be taxed as ordinary income or capital gains, unless you are investing through a tax‑deferred arrangement, such as a 401(k) plan or an individual retirement account. Distributions on investments made through tax-deferred arrangements may be taxed later upon withdrawal of assets from those accounts.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the Adviser or its affiliates may pay Intermediaries for certain activities related to the Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the Fund, or for other activities, such as marketing, educational training or other initiatives related to the sale or promotion of Shares. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Any such arrangements do not result in increased Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.
