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 Fund ("Shares"). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table or the example below.

Annual Fund Operating Expenses

(expenses that you pay each year as a percentage of the value of your investment)

Management Fees			0.19%
Other Expenses			0.00%
Total Annual Fund Operating Expenses (1)			0.19%

(1)The investment management agreement (the "Management Agreement") between the Fund and Principal Global Investors, LLC ("PGI") provides that, for the duration of the Management Agreement, PGI will pay all operating expenses of the Fund, except for the management fee, payments made under the Fund's Rule 12b-1 plan (if or when such fees are imposed), brokerage commissions and other expenses connected to the execution of portfolio transactions, interest expense, taxes, acquired fund fees and expenses, litigation expenses, tax reclaim recovery expenses and other extraordinary expenses.

Example

This 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 in the Fund for the time periods indicated and then redeem all of your shares at the ends of those periods. The Example also assumes that your investment has a 5% 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			5 years			10 years
Principal Investment Grade Corporate Active ETF			$19			$61			$107			$243

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. During the most recent fiscal year, the Fund's portfolio turnover rate was 102.6% of the average value of its portfolio.

Principal Investment Strategies

The Fund is an actively managed exchange-traded fund ("ETF") that seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets, plus any borrowings for investment purposes, in investment-grade corporate bonds and other fixed-income securities. "Investment grade" securities are rated BBB- or higher by S&P Global Ratings ("S&P Global") or Baa3 or higher by Moody's Investors Service, Inc. ("Moody's"). If a security has been rated by only one of the rating agencies, that rating will determine the security's rating; if the security is rated differently by the rating agencies, the highest rating will be used; and if the security has not been rated by either of the rating agencies, those selecting such investments will determine the security's quality.

The fixed-income securities in which the Fund invests include foreign securities, corporate securities, securities issued or guaranteed by the U.S. government or its agencies and instrumentalities, and securities issued or guaranteed by foreign governments payable in U.S. dollars. The portfolio is not managed to a particular maturity. Under normal circumstances, the Fund maintains an average portfolio duration that is within +/- 10% of the duration of the Bloomberg U.S. Corporate Investment Grade Bond Index, which as of September 30, 2025 was 6.81 years. The Fund actively trades securities.

The Fund invests in derivatives, including treasury futures for hedging or to otherwise manage fixed-income exposure, as well as credit default swaps and credit index futures, including buying and selling on individual securities and/or baskets of securities, to efficiently manage exposures to certain sectors or individual issuers. A derivative is a financial arrangement, the value of which is derived from, or based on, a traditional security, asset, or market index.

The Fund's strategies may result in the active and frequent trading of the Fund's portfolio securities.

Principal Risks

The value of your investment in the Fund changes with the value of the Fund's investments. Many factors affect that value, and it is possible to lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund are listed below in alphabetical order and not in order of significance.

Active Management Risk. There is no guarantee that the investment techniques, analyses, or judgments that the Fund's investment advisor and/or sub-advisor applies in making investment decisions for the Fund will produce the intended outcome or that the investments the advisor selects for the Fund will perform as well as other securities that were not selected for the Fund. The Fund may not achieve its investment objective, and it is not intended to be a complete investment program.

Counterparty Risk. Counterparty risk is the risk that the counterparty to a contract or other obligation will be unable or unwilling to honor its obligations.

2 of 5

Derivatives Risk. Derivatives may not move in the direction anticipated by the portfolio manager. Transactions in derivatives may increase volatility, cause the liquidation of portfolio positions when not advantageous to do so, and result in disproportionate losses that may be substantially greater than a fund's initial investment.

•Credit Default Swaps. Credit default swaps involve special risks in addition to those associated with swaps generally because they are difficult to value, are highly susceptible to liquidity and credit risk, and generally pay a return to the party that has paid the premium only in the event of an actual default by the issuer of the underlying obligation (as opposed to a credit downgrade or other indication of financial difficulty). The protection "buyer" in a credit default contract may be obligated to pay the protection "seller" an up-front payment or a periodic stream of payments over the term of the contract, provided, generally, that no credit event on a reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the "par value" (i.e., full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be required to deliver the related net cash amount, if the swap is cash settled. The Fund may be either the buyer or seller in the transaction.

•Futures. Futures contracts involve specific risks, including: the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract; possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; counterparty risk; and if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements.

Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate, credit quality, and liquidity risks. The market value of fixed-income securities generally declines when interest rates rise, and increased interest rates may adversely affect the liquidity of certain fixed-income securities. Moreover, an issuer of fixed-income securities could default on its payment obligations due to increased interest rates or for other reasons.

Foreign Securities Risk. The risks of foreign securities include loss of value as a result of: political or economic instability; nationalization, expropriation, or confiscatory taxation; settlement delays; and limited government regulation (including less stringent reporting, accounting, and disclosure standards than are required of U.S. companies).

Hedging Risk. A fund that implements a hedging strategy using derivatives and/or securities could expose the fund to the risk that can arise when a change in the value of a hedge does not match a change in the value of the asset it hedges. In other words, the change in value of the hedge could move in a direction that does not match the change in value of the underlying asset, resulting in a risk of loss to the Fund.

High Portfolio Turnover Risk. High portfolio turnover (more than 100%) caused by active and frequent trading of portfolio securities may result in accelerating the realization of taxable gains and losses, lower fund performance, and increased brokerage costs.

Market Trading Risks. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, and disruption to the activities of market makers, limited pool of authorized participants, or other participants and in the creation/redemption process of the Fund. ANY OF THESE FACTORS MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Portfolio Duration Risk. Portfolio duration is a measure of the expected life of a fixed-income security and its sensitivity to changes in interest rates. The longer a fund's average portfolio duration, the more sensitive the fund will be to changes in interest rates, which means funds with longer average portfolio durations may be more volatile than those with shorter durations.

Redemption and Large Transaction Risk. Ownership of the Fund's shares may be concentrated in one or a few large investors (such as funds of funds, institutional investors, and asset allocation programs) that may sell or purchase Fund shares in large quantities on the secondary market. These secondary market transactions may cause authorized participants to increase their purchases and redemptions of creation units

3 of 5

from the Fund. Purchases and redemptions of creation units primarily with cash rather than through in-kind delivery of portfolio securities may cause the Fund to incur certain costs, such as brokerage costs or taxable gains or losses that it might not have incurred if it had made a redemption in kind. These costs could be imposed on the Fund and thus decrease its NAV to the extent that the costs are not offset by a transaction fee payable by an authorized participant.

U.S. Government Securities Risk. Yields available from U.S. government securities are generally lower than yields from many other fixed-income securities. The value of U.S. government securities may be adversely impacted by changes in interest rates, changes in the credit rating of the U.S. government, or a default by the U.S. government.

U.S. Government-Sponsored Securities Risk. Securities issued by U.S. government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association, and the Federal Home Loan Banks are not issued or guaranteed by the U.S. government.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. The after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

The Bloomberg U.S. Aggregate Index is the Fund's primary broad-based securities market index. The Bloomberg U.S. Corporate Investment Grade Bond Index is included as an additional index for the Fund as it shows how the Fund's performance compares with the returns of an index of funds with similar investment objectives.

Purchase and Sale of Fund Shares

The Fund issues and redeems Shares at net asset value ("NAV") only with authorized participants ("APs") who have entered into agreements with the Fund's distributor and only in blocks of 50,000 Shares (each block of Shares is called a "Creation Unit"), or multiples thereof ("Creation Unit Aggregations"), in exchange for the deposit or delivery of a basket of securities that the Fund specifies each day. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund. Typically, the basket of assets will be made up of securities, but may include a cash component. (See "Purchase and Redemption of Creation Units" in the Statement of Additional Information for more information.)

Shares of the Fund are listed for trading on NYSE Arca, Inc. Individual Shares may only be bought and sold in the secondary market through a broker or dealer at a market price. Because Shares trade at market prices rather than NAV, Shares may trade at prices greater than NAV (at a premium), at NAV, 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 or selling Shares on the secondary market (the bid-ask spread).

You can access recent information, including information on the Fund's net asset value, market price, premiums and discounts, and bid-ask spreads at www.PrincipalAM.com.

Tax Information

The Fund's distributions you receive are generally subject to federal income tax as ordinary income or capital gain and may also be subject to state and local taxes, unless you are tax-exempt or your account is tax-deferred in which case your distributions would be taxed when withdrawn from the tax-deferred account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary, the Fund and its related companies may pay the intermediary for the sale of Fund 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 the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
