---

<sup>(1)</sup> Fees have been restated to reflect current fees.

<sup>(2)</sup> Principal Global Investors, LLC ("PGI"), the investment advisor, has contractually agreed to limit the Fund's expenses by paying, if necessary, expenses normally payable by the Fund (excluding interest expense, expenses related to fund investments, acquired fund fees and expenses, expenses related to the ReFlow liquidity program, and tax reclaim recovery expenses and other extraordinary expenses) to maintain a total level of operating expenses (expressed as a percent of average net assets on an annualized basis) not to exceed 1.39% for Institutional Class shares. In addition, for Class R-6, the expense limit will maintain "Other Expenses" (expressed as a percent of average net assets on an annualized basis) not to exceed 0.04% (excluding interest expense, expenses related to fund investments, acquired fund fees and expenses, expenses related to the ReFlow liquidity program, and tax reclaim recovery expenses and other extraordinary expenses). It is expected that the expense limits will continue through the period ending December 30, 2026; however, Principal Funds, Inc. and PGI, the parties to the agreement, may mutually agree to terminate the expense limits prior to the end of the period. Subject to applicable expense limits, the Fund may reimburse PGI for expenses incurred during the current fiscal year.

**Example**

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual 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 end 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. The calculation of costs takes into account any applicable contractual fee waivers and/or expense reimbursements for the period noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | &nbsp;&nbsp;&nbsp;**1 year** | &nbsp;&nbsp;&nbsp;**3 years** | &nbsp;&nbsp;&nbsp;**5 years** | &nbsp;&nbsp;&nbsp;**10 years** |
| **Class A** | $549 | $914 | $1303 | $2391 |
| **Institutional Class** | 150 | 467 | 807 | 1768 |
| **Class R-6** | 135 | 483 | 854 | 1898 |

---

**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 138.7% of the average value of its portfolio.

**Principal Investment Strategies**

Principal Global Investors, LLC ("PGI"), the Fund's investment advisor, seeks to combine diversified investment strategies efficiently and systematically so that the Fund generates a positive total return with relatively low volatility and low sensitivity or correlation to market indices. In managing the Fund, PGI allocates the Fund's assets among the investment strategies described below, which are executed by PGI or one or more of the Fund's sub-advisors. PGI has considerable latitude in allocating the Fund's assets. The Fund will use strategies and sub-advisors to varying degrees and may change allocations, add new or eliminate existing strategies and sub-advisors, and temporarily or permanently reduce allocations from time to time such that the Fund would have little or no assets allocated to a particular strategy or sub-advisor.

The Fund invests in a broad range of instruments, including, but not limited to, equities, bonds, currencies, commodities, convertible securities, and bank loans. Under normal market conditions, the Fund invests in securities of issuers located throughout the world, including the U.S., invests at least 30% of its net assets in foreign and emerging market securities, and holds investments tied economically to at least twenty countries.

2 of 8

------

The Fund invests in equity securities regardless of market capitalization size (small, medium, or large) and style (growth or value). The Fund invests in investment-grade and below-investment-grade bonds (sometimes called "high yield bonds" or "junk bonds"), which are rated at the time of purchase Ba1 or lower by Moody's Investors Service, Inc. ("Moody's") and BB+ or lower by S&P Global Ratings ("S&P Global"). If the bond has been rated by only one of the rating agencies, that rating will determine the bond's rating; if the bond is rated differently by the rating agencies, the highest rating will be used; and if the bond has not been rated by either of the rating agencies, those selecting such investments will determine the bond's quality. The fixed-income portion of the Fund is not managed to a particular maturity or duration. The Fund's strategies may result in the active and frequent trading of the Fund's portfolio securities.

The Fund invests in derivative instruments. A derivative is a financial arrangement, the value of which is derived from, or based on, a traditional security, asset, or market index. The strategies use different types of derivative instruments for various purposes, including to gain exposure to securities and to attempt to reduce risk. The Fund may invest in money market funds in order to provide collateral for certain derivative positions and other financial instruments.

The Fund takes long and short positions in securities and derivative instruments. Short positions benefit from a decrease in price of the underlying instrument and lose value if the price of the underlying instrument increases. Long positions profit if the value of the instrument increases. Simultaneously engaging in long investing and short selling reduces the net exposure to general market movements. The Fund also takes relative value positions in an effort capitalize on price differences between similar securities or relative value among securities of the same company. The Fund also invests a portion of the proceeds it receives from a short position into long positions.

**Relative Value.** This strategy uses a flexible approach to invest primarily in fixed-income securities and instruments related to credit, currencies, and interest rates, while employing risk-management strategies. This strategy uses a variety of techniques to obtain market exposure, such as derivative instruments, including options, futures, forwards, and swaps (including credit default swaps); entering into a series of purchase and sale contracts; purchasing securities on a when-issued, delayed delivery, or forward-commitment basis; and taking short positions in such instruments. This strategy may obtain investment exposure substantially through derivatives instruments, may use such instruments in an effort to minimize volatility, and may use equity futures for hedging purposes.

A portion of this strategy takes long and short positions in selected emerging market issuers when those selecting such investments identify factors (such as macro-economic factors, country-specific factors, or credit-specific factors) that they believe will drive substantial appreciation or depreciation of the particular exposure. The strategy's geographic focus is derived from economic and political developments and the specific nature of local jurisdictions in the emerging markets.

**Equity Long/Short.** This strategy provides long and short exposure to a diversified portfolio of U.S. and foreign, including emerging market, equity securities. Those selecting such investments simultaneously invest long in equities they expect to increase in value and either short sell equities they expect to decrease in value, or hedge equity market exposure another way (for example, by using derivatives such as futures, options, or swaps). This strategy uses two methods of analysis: fundamental analysis, which examines a company's financial statements and operations, especially sales, earnings, products, management, and competition; and quantitative analysis, which uses mathematical models to evaluate a company's measurable characteristics such as revenue, earnings, margins, and market share.

**Event-Driven.** This strategy invests in securities on the basis that a specific event or catalyst will affect future prices. This strategy attempts to capitalize on price discrepancies and returns generated by corporate activity, such as merger arbitrage, where the Fund holds a long/short portfolio of securities of companies involved in mergers.

**Global Macro.** This strategy provides long and short exposure to a broad spectrum of global assets (including equities, currencies, fixed-income securities, bonds, commodities, and interest rates) in an effort to profit from movement in the prices of securities that are highly sensitive to macroeconomic conditions. The managed futures portion of this strategy uses quantitative selection models to help predict movements in these markets. In pursuing this strategy, the Fund, either directly or through its wholly-owned subsidiary organized under the laws of the Cayman Islands (the "Cayman Subsidiary"), invests in commodity-linked derivatives and in instruments such as fixed-income securities, cash and cash equivalents, and/or U.S. government securities, either as investments or to serve as margin or collateral for derivative positions.

3 of 8

------

Commodities are assets that have tangible properties, such as oil, coal, natural gas, agricultural products, industrial metals, livestock, and precious metals. In pursuing certain commodity strategies, the Fund invests its assets in the Cayman Subsidiary to gain exposure to the commodity markets within the limitations of the federal tax law requirements applicable to regulated investment companies under the Internal Revenue Code. The Fund's investments in its Cayman Subsidiary at any time will not exceed 25% of the Fund's net assets.

**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.

**Arbitrage Trading Risk.** The underlying relationships between securities in which the Fund takes arbitrage investment positions may change in an adverse manner, in which case the Fund may realize losses.

**Asset Allocation Risk.** A fund's selection and weighting of asset classes and allocation among sub-advisors may cause it to underperform other funds with a similar investment objective.

**Bank Loans Risk.** Changes in economic conditions are likely to cause issuers of bank loans (also known as senior floating rate interests) to be unable to meet their obligations. In addition, the value of the collateral securing the loan (if any) may decline, causing a loan to be substantially unsecured. Underlying credit agreements governing the bank loans, reliance on market makers, priority of repayment, and overall market volatility may harm the liquidity of loans.

**Cayman Subsidiary Risk.** The Fund is subject to the particular risks associated with the investments of the Fund's wholly-owned Cayman Subsidiary, namely commodity-related investments risk, counterparty risk, and derivatives risk. The Cayman Subsidiary is not registered under the Investment Company Act of 1940 and is not subject to all the investor protections of the Investment Company Act of 1940. The laws of the Cayman Islands and/or the United States (including the IRS position on income earned from wholly-owned subsidiaries described in past IRS private letter rulings) may change, resulting in the inability of the Fund and/or the Cayman Subsidiary to operate as described in this Prospectus.

**Commodity-Related Investments Risk.** The value of commodities investments will generally be affected by overall market movements and factors specific to a particular industry or commodity, which may include weather, embargoes, tariffs, and economic health, political, international, regulatory, and other developments. Exposure to the commodities markets may subject the Fund to greater volatility than investments in traditional securities.

**Convertible Securities Risk.** Convertible securities are securities that are convertible into common stock. Convertible securities are subject to credit and interest rate risks associated with fixed-income securities and to stock market risk associated with equity securities.

**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.

**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.

• **Currency Contracts.** Derivatives related to currency contracts involve the specific risk of government action that would restrict the ability of the Fund to deliver or receive currency.

4 of 8

------

• **Forward Contracts, Futures, and Swaps.** Forward contracts, futures, and swaps 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 forward contract, future, or swap; possible lack of a liquid secondary market for a forward contract, future, or swap and the resulting inability to close a forward contract, future, or swap 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.

• **Options.** Options 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 options; counterparty risk; difference in trading hours for the options markets and the markets for the underlying securities (rate movements can take place in the underlying markets that cannot be reflected in the options markets); and an insufficient liquid secondary market for particular options.

**Emerging Markets Risk.** Investments in emerging markets may have more risk than those in developed markets because the emerging markets are less developed and more illiquid. Emerging markets can also be subject to increased social, economic, regulatory, and political uncertainties and can be extremely volatile. The U.S. Securities and Exchange Commission, the U.S. Department of Justice, and other U.S. authorities may be limited in their ability to pursue bad actors in emerging markets, including with respect to fraud.

**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.

• **Smaller Companies Risk.** Investments in smaller companies may involve greater risk and price volatility than investments in larger, more mature companies. Smaller companies may have limited product lines, markets, or financial resources; lack the competitive strength of larger companies; have less experienced managers; or depend on a few key employees. Their securities often are less widely held and trade less frequently and in lesser quantities, and their market prices often fluctuate more, than securities of larger companies.

• **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.

**Event-Driven Trading Risk.** Event-driven trading involves the risk that the special situation may not occur as anticipated, if at all, and that the market price of a stock declines.

**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 Currency Risk.** Risks of investing in securities denominated in, or that trade in, foreign (non-U.S.) currencies include changes in foreign exchange rates and foreign exchange restrictions.

**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.

5 of 8

------

**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.

**High Yield Securities Risk.** High yield fixed-income securities (commonly referred to as "junk bonds") are subject to greater credit quality risk than higher rated fixed-income securities and should be considered speculative.

**Investment Company Securities Risk.** A fund that invests in another investment company (for example, another fund or an exchange-traded fund (or ETF)) is subject to the risks associated with direct ownership of the securities in which such investment company invests. Fund shareholders indirectly bear their proportionate share of the expenses of each such investment company.

**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 redeem or purchase shares in large quantities. These transactions may cause the Fund to sell securities to meet redemptions or to invest additional cash at times it would not otherwise do so, which may result in increased transaction costs, increased expenses, changes to expense ratios, and adverse effects to Fund performance. Such transactions may also accelerate the realization of taxable income if sales of portfolio securities result in gains. Moreover, reallocations by large shareholders among share classes of a fund may result in changes to the expense ratios of affected classes, which may increase the expenses paid by shareholders of the class that experienced the redemption.

**Securitized Products Risk.** Investments in securitized products are subject to risks similar to traditional fixed-income securities, such as credit, interest rate, liquidity, prepayment, extension, and default risk, as well as additional risks associated with the nature of the assets and the servicing of those assets. Unscheduled prepayments on securitized products may have to be reinvested at lower rates. A reduction in prepayments may increase the effective maturities of these securities, exposing them to the risk of decline in market value over time (extension risk). With respect to securities that are delivered in TBA transactions, there is a risk that the actual securities received by the Fund may be less favorable than what was anticipated when entering into the transaction.

**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.

**Performance**

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/mutualfundperformance.

The bar chart shows the investment returns of the Fund's Class A shares for each full calendar year of operations for 10 years (or, if shorter, the life of the Fund). These annual returns do not reflect sales charges on Class A shares; if they did, results would be lower. 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.

6 of 8

------

For periods prior to the inception date of Class R-6 shares (June 12, 2017), the performance shown in the table for Class R-6 shares is that of the Fund's Institutional Class shares, adjusted to reflect the fees and expenses of the Class R-6 shares. However, where this adjustment for fees and expenses results in performance for Class R-6 that is higher than the historical performance of the Institutional Class shares, the historical performance of the Institutional Class shares is used. These adjustments result in performance for such periods that is no higher than the historical performance of the Institutional Class shares, which were first sold on October 24, 2011.

You may purchase or redeem shares on any business day (normally any day when the New York Stock Exchange is open for regular trading) through your plan, intermediary, or Financial Professional by sending a written request to Principal Funds at P.O. Box 219971, Kansas City, MO 64121-9971 (regular mail) or 801 Pennsylvania Ave., Ste. 219971, Kansas City, MO 64105-1307 (overnight mail); calling us at 1-800-222-5852; or accessing our website (www.principal.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 (such as a bank), 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, or to recommend one share class of the Fund over another share class. Ask your salesperson or visit your financial intermediary's website for more information.
