The Fund's Prospectus and Statement of Additional Information, both dated November 1, 2026, as may be amended or supplemented, are incorporated by reference into this Summary Prospectus.

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.

(2)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, and tax reclaim recovery expenses and other extraordinary expenses.

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:

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 23.9% of the average value of its portfolio.

Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of U.S. companies with very large ("mega") market capitalizations. The Fund considers a company to be a mega-cap company if its market capitalization falls within the range of market capitalizations of the largest 50 companies included in the S&P 500 ® Index or a market capitalization of at least $250 billion. As of September 30, 2026, the market capitalization range of the companies in the largest 50 companies in the S&P 500 ® Index was between approximately $163.4 billion and $5.5 trillion.

For security selection and portfolio construction, Principal Global Investors, LLC ("PGI") uses a proprietary quantitative model. The model is designed to identify equity securities of companies in the S&P 500 ® Index that have the largest market capitalizations, while typically applying higher weight to securities that PGI ranks higher on financial strength measures, including but not limited to a company’s balance sheet and its ability to meet short and long term debt obligations, cash flow, and pricing power. "Pricing power" refers to the extent to which a company can raise the prices of its products without reducing the demand for them. The Fund invests in equity securities of different styles (growth or value).

The Fund's holdings are expected to be rebalanced at least annually. However, PGI may make any adjustments to the model and Fund holdings at its discretion. In constructing and revising the model and managing the Fund’s investments, PGI uses insights from diverse sources, including internal investment research, industry reports, and data from third-party consultants and other service providers, to develop and refine its investment themes and identify and take advantage of trends that may impact the Fund and its holdings.

The Fund is considered non-diversified, which means it can invest a higher percentage of assets in securities of individual issuers than a diversified fund. As a result, changes in the value of a single investment could cause greater fluctuations in the Fund's share price than would occur in a more diversified fund.

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. The Fund's investments are actively managed by the investment team and do not track an index. Consequently, 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.

Equity Securities Risk. A variety of factors can negatively impact the value of equity securities held by a fund, including a decline in the issuer’s financial condition, unfavorable performance of the issuer’s sector or industry, or changes in response to overall market and economic conditions. A fund’s principal market segment(s) (such as market capitalization or style) may underperform other market segments or the equity markets as a whole.

•Growth Style Risk. Growth investing entails the risk that if growth companies do not increase their earnings at a rate expected by investors, the market price of their stock may decline significantly, even if earnings show an absolute increase. Growth company stocks also typically lack the dividend yield that can lessen price declines in market downturns.

•Value Style Risk. Value investing entails the risk that value stocks may continue to be undervalued by the market for extended periods, including the entire period during which the stock is held by a fund, or the events that would cause the stock price to increase may not occur as anticipated or at all. Moreover, a stock that appears to be undervalued actually may be appropriately priced at a low level and, therefore, would not be profitable for the fund.

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.

Model Risk. Because PGI uses quantitative models to select and hold investments, the Fund may hold investments that present risks that an investment advisor researching individual investments might seek to avoid. Moreover, models may be predictive in nature and depend heavily on the accuracy and reliability of historical data that is supplied by others and may be incorrect or incorrectly input. The Fund bears the risk that the quantitative models used will not be successful in identifying trends or in determining the size and direction of investment positions that will enable the Fund to achieve its investment objective.

Non-Diversification Risk. A non-diversified fund may invest a high percentage of its assets in the securities of a small number of issuers and is more likely than diversified funds to be significantly affected by a specific security’s poor performance.

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 from the Fund. Redemptions by large shareholders could have a significant negative impact on the Fund, including on the Fund’s liquidity. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the Fund's exchange and may, therefore, have a material upward or downward effect on the market price of the shares.

The following information provides some indication of the risks of investing in the Fund. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. You may get updated performance information at www.principalam.com/etfperformance.

The bar chart shows the investment returns of the Fund’s shares for each full calendar year of operations for 10 years (or, if shorter, the life of the Fund). The table shows for the last one, five, and ten calendar year periods (or, if shorter, the life of the Fund), how the Fund’s average annual total returns compare with those of one or more broad measures of market performance.

Prior to June 10, 2022, the objective and strategy of the Fund differed from its current objective and strategy. Accordingly, performance of the Fund for periods prior to that date may not be representative of the performance the Fund would have achieved had the Fund been following its current objective and strategy.

(1)Prior to June 10, 2022, the objective and strategy of the Fund differed from its current objective and strategy. Accordingly, performance of the Fund for periods prior to that date may not be representative of the performance the Fund would have achieved had the Fund been following its current objective and strategy.

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 Fund issues and redeems Shares at net asset value ("NAV") only with authorized participants who have entered into agreements with the Fund's distributor 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 The Nasdaq Stock Market LLC. 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.

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.

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.
