(1) Principal Global Investors, LLC ("PGI"), the investment advisor, has contractually agreed to waive a portion of the Fund's management fees through the period ending February 28, 2027. The fee waiver will reduce the Fund's management fees by 0.02% (expressed as a percent of average net assets on an annualized basis). It is expected that the fee waiver will continue through the period disclosed; however, Principal Funds, Inc. and PGI, the parties to the agreement may mutually agree to terminate the fee waiver prior to the end of the period.

(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, 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 0.69% for Institutional Class shares. It is expected that the expense limit will continue through the period ending February 28, 2027; 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.

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	$652	$873	$1,111	$1,793
Class J	189	282	491	1,094
Institutional Class	70	236	415	936
Class R-3	122	385	668	1,476
Class R-5	91	288	502	1,118
Class R-6	65	209	366	821

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 79.6% 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 value companies with medium market capitalizations (MidCap). For this Fund, value companies with medium market capitalizations are (i) those with market capitalizations within the range of companies comprising the Russell MidCap ® Index (as of January 30, 2026, this range was between approximately $1.2 billion and $88.7 billion), and (ii) included within at least one of the following value indices: the MSCI All Country World IMI Value Index, the S&P 1500 Value Index, or the Russell 3000 Value Index. The Fund invests in value equity securities, an investment strategy that emphasizes buying equity securities that appear to be undervalued.

The Fund is primarily actively managed by the sub-advisors. In addition, Principal Global Investors, LLC may invest up to 30% of the Fund’s assets using an index sampling strategy designed to match the performance of the Russell MidCap® Value Index.

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.

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.

•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.

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.

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 Institutional Class 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.

For periods prior to the inception date of Classes A and R-6 shares (April 2, 2019), the performance shown in the table for these newer classes is that of the Fund’s Institutional Class shares, adjusted to reflect the fees and expenses of the newer class. These adjustments result in performance for such periods that is no higher than the historical performance of the Institutional Class shares.


	1 Year	5 Years	10 Years
Institutional Class Return Before Taxes	6.09%	10.23%	9.96%
Institutional Class Return After Taxes on Distributions	4.38%	7.67%	7.91%
Institutional Class Return After Taxes on Distributions and Sale of Fund Shares	4.83%	7.64%	7.60%
Class A Return Before Taxes	(0.14)%	8.60%	8.94%
Class J Return Before Taxes	4.89%	10.05%	9.72%
Class R-3 Return Before Taxes	5.51%	9.70%	9.41%
Class R-5 Return Before Taxes	5.87%	10.04%	9.75%
Class R-6 Return Before Taxes	6.06%	10.30%	10.03%
Russell 3000 Index (reflects no deduction for fees, expenses, or taxes)	17.15%	13.15%	14.29%

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 Institutional Class shares only and would be different for the other share classes.

The Russell 3000 Index is the Fund's primary broad-based securities market index. The Russell MidCap Value 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.

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 (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.
