CALIFORNIA MUNICIPAL FUND
Objective
The Fund seeks to provide as high a level of current income that is exempt from federal and state personal income tax as is consistent with prudent investment management and preservation of capital.
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. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in Class A Shares of Principal Funds, Inc. More information about these and other discounts is available from your financial intermediary and in “Choosing a Share Class and The Costs of Investing” beginning on page 426 of the Fund’s Prospectus, Appendix B to the Prospectus titled “Intermediary-Specific Sales Charge Waivers and Reductions,” and “Multiple Class Structure” beginning on page 70 of the Fund’s Statement of Additional Information.

If you purchase Institutional Class shares through certain programs offered by certain financial intermediaries, you may be required to pay a commission and/or other forms of compensation to the broker, or to your Financial Professional or other financial intermediary.

(2)    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, 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 0.46% for Institutional Class shares. It is expected that the expense limit will continue through the period ending February 28, 2025; however, Principal Funds, Inc. and PGI, the parties to the agreement, may mutually agree to terminate the expense limit 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 assumes conversion of the Class C shares to Class A shares after the eighth year. 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:
1 year
3 years
5 years
10 years
Class A $462 $648 $850 $1,430
Class C 276 545 939 1,818
Institutional Class 64 210 369 831
With respect to Class C shares, you would pay the following expenses if you did not redeem your shares (all other classes would be the same as in the above example):
1 year
3 years
5 years
10 years
Class C  $176  $545  $939  $1,818
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 31.5% of the average value of its portfolio.
Principal Investment Strategies
Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in California municipal obligations (securities issued by or on behalf of state or local governments and other public authorities) at the time of purchase. Generally, these municipal obligations pay interest that is exempt from state personal income tax and federal income tax. These obligations may include bonds that generate interest payments that are subject to the federal individual alternative minimum tax. The Fund’s investment in municipal obligations include industrial revenue bonds. The Fund invests up to 20% of its assets in 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 Fund also invests in inverse floating rate obligations (variable rate debt instruments that pay interest at rates that move in the opposite direction of prevailing interest rates), which are generally more volatile than other types of municipal obligations and may involve leverage.
Under normal circumstances, the Fund maintains an average portfolio duration that is within ±50% of the duration of the Bloomberg California Municipal Bond Index, which as of January 31, 2024 was 5.26 years. The Fund is not managed to a particular maturity.
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.
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.
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.
6


Geographic Concentration Risk. A fund that invests significant portions of its assets in municipal obligations and bonds in particular geographic areas (a particular state, such as California, or a particular country or region) has greater exposure than other funds to economic conditions and developments in those areas.
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.
Industrial Revenue Bond Risk. The Fund will be sensitive to, and its performance will depend to a greater extent on, the overall condition and performance of industrial revenue bonds. These revenue bonds are issued by or on behalf of public authorities to obtain funds to finance various public and/or privately operated facilities, including those for business and manufacturing, housing, sports, pollution control, airport, mass transit, port, and parking facilities. These bonds are normally secured only by the revenues from the project and not by state or local government tax payments. Consequently, the credit quality of these bonds is dependent upon the ability of the user of the facilities financed by the bonds and any guarantor to meet its financial obligations.
Inverse Floating Rate Investments Risk. Inverse floating rate investments are extremely sensitive to changes in interest rates and, in some cases, their market value may be extremely volatile.
Leverage Risk. Leverage created by borrowing or certain types of transactions or investments may impair the fund’s liquidity, cause it to liquidate positions at an unfavorable time, increase volatility of the fund’s net asset value, or diminish the fund’s performance.
Municipal Obligations Risk. Principal and interest payments on municipal securities may not be guaranteed by the issuing body and may be payable only from a particular source. That source may not perform as expected, and payment obligations may not be made or made on time.
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.
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.
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.
For periods prior to the inception date of Institutional Class shares (March 1, 2015), the performance shown in the table for Institutional Class shares is that of the Fund’s Class A shares, adjusted to reflect the fees and expenses of Institutional Class shares. However, where the adjustment for fees and expenses results in performance for Institutional Class shares that is higher than the historical performance of the Class A shares, the historical performance of Class A shares is used (without respect to sales charges, which are not applicable to Institutional Class shares). These adjustments result in performance for such periods that is no higher than the historical performance of the Class A shares.

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. After-tax returns are shown for Class A shares only and would be different for the other share classes.
Effective March 1, 2024, the Fund changed its primary broad-based index to the Bloomberg Municipal Bond Index in order to meet the revised definition of “broad-based securities market index.” The Bloomberg California Municipal 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.

Box 219971, Kansas City, MO 64121-9971 (regular mail) or 430 W. 7th Street, Ste. 219971, Kansas City, MO 64105-1407 (overnight mail); calling us at 1-800-222-5852; or accessing our website (www.principal.com).
Class C shares are subject to an 8-year automatic conversion plan whereby Class C shares held for eight years after purchase will automatically convert to Class A shares of the same Fund. See Purchase of Fund Shares for more information.
Tax Information
While the Fund intends to distribute income that is exempt from regular federal and California income taxes, a portion of the Fund’s distributions may be subject to California or federal income taxes or to the federal individual alternative minimum tax.
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.

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 9.9% of the average value of its portfolio.
Principal Investment Strategies
Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in fixed-income securities. The Fund invests primarily in a diversified pool of investment-grade fixed-income securities, including corporate securities, U.S. government securities, asset-backed securities and mortgage-backed securities (securitized products) (including collateralized mortgage obligations), and foreign 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”), at the time of purchase. If the 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 is 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 Fund is not managed to a particular maturity. Under normal circumstances, the Fund maintains an average portfolio duration that is within ±25% of the duration of the Bloomberg U.S. Aggregate Bond Index, which as of January 31, 2024 was 6.11 years.
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.
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).
11


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.
Real Estate Securities Risk. Investing in real estate securities subjects the fund to the risks associated with the real estate market (which are similar to the risks associated with direct ownership in real estate), including declines in real estate values, loss due to casualty or condemnation, property taxes, interest rate changes, increased expenses, cash flow of underlying real estate assets, regulatory changes (including zoning, land use, and rents), and environmental problems, as well as to the risks related to the management skill and creditworthiness of the issuer.
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).
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.
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.
For periods prior to the inception date of Class R-6 shares (November 25, 2014), the performance shown in the table for Class R-6 shares is that of the Fund’s Class A shares, adjusted to reflect the fees and expenses of Class R-6 shares. However, where the adjustment for fees and expenses results in performance for Class R-6 shares that is higher than the historical performance of the Class A shares, the historical performance of the Class A shares is used (without respect to sales charges, which are not applicable to Class R-6 shares). These adjustments result in performance for such periods that is no higher than the historical performance of the Class A shares.

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:
1 year
3 years
5 years
10 years
Class A  $454  $660  $884  $1,526
Class J  191  284  493  1,096
Institutional Class  49  178  318  727
Class R-1  133  415  718  1,579
Class R-3  102  318  552  1,225
Class R-4  83  259  450  1,002
Class R-5  70  221  384  859
With respect to Class J shares, you would pay the following expenses if you did not redeem your shares (all other classes would be the same as in the above example):
1 year
3 years
5 years
10 years
Class J  $91  $284  $493  $1,096
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 156.0% of the average value of its portfolio.
Principal Investment Strategies
Under normal circumstances, the Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in bonds or other debt securities at the time of purchase. Such investments include securities issued or guaranteed by the U.S. government or its agencies or instrumentalities; asset-backed securities and mortgage-backed securities (securitized products, including collateralized mortgage obligations); corporate bonds; and foreign securities, including emerging market securities. The Fund invests in investment-grade securities and, with respect to up to 25% of its assets, in below-investment-grade securities (sometimes called “high yield” or “junk”), 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 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 Fund is not managed to a particular maturity. Under normal circumstances, the Fund maintains an average portfolio duration that is within ±25% of the duration of the Bloomberg U.S. Aggregate Bond Index, which as of January 31, 2024 was 6.11 years. The Fund’s strategies may result in the active and frequent trading of the Fund’s portfolio securities.
The Fund enters into dollar roll transactions, which may involve leverage. The Fund invests in derivatives, including Treasury futures and interest rate swaps to manage the fixed-income exposure (including for hedging purposes) and credit default swaps to increase or decrease, in an efficient manner, 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.
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.
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.
16


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 and Swaps. These derivative instruments 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 instruments; possible lack of a liquid secondary market for an instrument and the resulting inability to close it when desired; counterparty risk; and if the fund has insufficient cash, it may have to sell securities from its portfolio to meet any applicable daily variation margin requirements.
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.
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.
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.
Leverage Risk. Leverage created by borrowing or certain types of transactions or investments may impair the fund’s liquidity, cause it to liquidate positions at an unfavorable time, increase volatility of the fund’s net asset value, or diminish the fund’s performance.
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.
Real Estate Securities Risk. Investing in real estate securities subjects the fund to the risks associated with the real estate market (which are similar to the risks associated with direct ownership in real estate), including declines in real estate values, loss due to casualty or condemnation, property taxes, interest rate changes, increased expenses, cash flow of underlying real estate assets, regulatory changes (including zoning, land use, and rents), and environmental problems, as well as to the risks related to the management skill and creditworthiness of the issuer.
17


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).
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.

(2)    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, 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 0.68% 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 0.02%, (excluding interest expense, expenses related to fund investments, acquired fund fees and expenses, and tax reclaim recovery expenses and other extraordinary expenses). It is expected that the expense limits will continue through the period ending February 28, 2025; 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 assumes conversion of the Class C shares to Class A shares after the eighth year. 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:
1 year
3 years
5 years
10 years
Class A  $478  $697  $933  $1,609
Class C  284  569  980  1,927
Institutional Class 72 241 425 959
Class R-6 70 227 398 892
With respect to Class C shares, you would pay the following expenses if you did not redeem your shares (all other classes would be the same as in the above example):
1 year
3 years
5 years
10 years
Class C $184 $569 $980 $1,927
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 75.1% of the average value of its portfolio.
Principal Investment Strategies
The Fund generally invests a majority of its assets in fixed-income securities, such as investment-grade corporate bonds, high yield bonds (also known as “junk” bonds), preferred securities, securitized products, and emerging market debt securities, in an effort to provide incremental yields over a portfolio of government securities. Such securities include instruments with variable or floating interest rates. The fixed-income portion of the Fund is not managed to a particular maturity or duration. The Fund invests in foreign, including emerging market, securities. The Fund uses derivative strategies. A derivative is a financial arrangement, the value of which is derived from, or based on, a traditional security, asset, or market index.
In managing the Fund, Principal Global Investors, LLC (“PGI”), the Fund’s investment advisor, determines the Fund's strategic asset allocation among actively managed and passively managed (index) strategies that are executed by PGI and multiple sub-advisors. PGI has considerable latitude in allocating the Fund's assets among the general investment categories listed below. The Fund uses 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.
•Investment-grade corporate securities, which are rated at the time of purchase Baa3 or higher by Moody’s Investors Service (“Moody’s”) or BBB- or higher by S&P Global Ratings (“S&P Global”).
•High yield and other income-producing securities, including bank loans and corporate bonds. “High yield” securities are below investment grade securities (sometimes called “junk”), which are rated at the time of purchase Ba1 or lower by Moody's and BB+ or lower by S&P Global. These securities offer a higher yield than other, higher rated securities, but they carry a greater degree of risk and are considered speculative with respect to the issuer's ability to pay interest and to repay principal. This portion of the Fund also invests in currency forwards and currency options to hedge currency risk.
•Preferred securities, focusing primarily on the financial services and utility industries.
21


•Diversified portfolio of fixed-income securities, including those issued by governments and their agencies and corporate entities in emerging markets. This portion of the Fund also invests in interest rate swaps or Treasury futures to manage fixed-income exposure; credit default swaps to increase or decrease in an efficient manner exposures to certain sectors or individual issuers; total return swaps to increase or decrease in an efficient manner exposures to certain sectors; and currency forwards and currency options to hedge currency risk and express views on the direction of currency.
•Securitized products such as asset-backed securities and mortgage-backed securities, including commercial mortgage-backed securities, which are bonds secured by first mortgages on commercial real estate.
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.
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.
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 through exchange controls that would restrict the ability of the fund to deliver or receive currency.
•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.
22


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.
Floating and Variable Rate Securities Risk. The market prices of securities with variable and floating interest rates are generally less sensitive to interest rate changes than are the market prices of securities of fixed interest rates. Floating and variable rate securities may decline in value if market interest rates or interest rates paid by them do not move as expected. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund’s ability to sell the securities at any given time.
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.
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.
Index (Passive) Strategy Risk. An index (passive) fund (or passive strategy that is part of a fund) has operating and other expenses while an index does not. As a result, over time, index funds tend to underperform the index. The correlation between an index strategy’s performance and index performance may also be affected by the type of passive investment approach used (sampling or replication), changes in securities markets, changes in the composition of the index, and the timing of purchases and sales of shares.
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.
Preferred Securities Risk. Because preferred securities have a lower priority claim on assets or earnings than senior bonds and other debt instruments in a company’s capital structure, they are subject to greater credit and liquidation risk than more senior debt instruments. In addition, preferred securities are subject to other risks, such as limited or no voting rights, deferring or skipping distributions, interest rate risk, and redeeming the security prior to any stated maturity date.
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).

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.
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 Class R-6 shares. These adjustments result in performance for such periods that is no higher than the historical performance of the Institutional Class shares.

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 42.2% of the average value of its portfolio.
Principal Investment Strategies
The Fund invests primarily in foreign equity securities. The Fund has no limitation on the percentage of assets that are invested in any one country or denominated in any one currency, but the Fund typically invests in foreign securities of at least 20 countries. Primary consideration is given to securities of issuers of developed areas (for example, Japan, Western Europe, Canada, Australia, Hong Kong, and Singapore); however, the Fund also invests in emerging market securities. The Fund invests in equity securities regardless of market capitalization size (small, medium, or large) and style (growth or value).
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.
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.
27


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.
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).
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.
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.
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.
For periods prior to the inception date of Class R-6 shares (March 1, 2019), the performance shown in the table for Class R-6 shares is that of the Fund’s Class R-3 shares, adjusted to reflect the fees and expenses of Class R-6 shares. However, where the adjustment for fees and expenses results in performance for Class R-6 shares that is higher than the historical performance of the Class R-3 shares, the historical performance of the Class R-3 shares is used. These adjustments result in performance for such periods that is no higher than the historical performance of the Class R-3 shares.

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.
