Rowe Price Tax-Free Short-Intermediate Fund, Inc. 2022-07-01 Tax-Free Short-Intermediate Fund Investment Objective(s) The fund seeks to provide, consistent with modest price fluctuation, a high level of income exempt from federal income taxes by investing primarily in short- and intermediate-term investment-grade municipal securities. Fees and Expenses This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the fund. You may also incur brokerage commissions and other charges when buying or selling shares of the fund, which are not reflected in the table or example below.

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, that your investment has a 5% return each year, and that the fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 48 151 263 591 36 113 197 443 80 249 433 966 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 the fund’s shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 23.9% of the average value of its portfolio. 0.239 Principal Investment Strategies The fund invests primarily in short-term municipal securities (maturities of less than three years) and intermediate-term municipal securities (maturities between three and ten years). The fund’s weighted average maturity normally ranges from two to five years and is not expected to exceed five years. Most investments are in investment-grade securities, which are securities rated in one of the four highest credit rating categories as determined by at least one established credit rating agency or, if unrated, deemed by T. Rowe Price to be of comparable quality. T. Rowe Price’s active investment management approach emphasizes the value of in-depth fundamental credit research, diversification, and risk management practices. By using fundamental research, T. Rowe Price seeks to select investments for the fund’s portfolio based on its outlook for the different sectors of the tax-free municipal market (for example, T. Rowe Price may emphasize revenue bonds instead of state and local general obligation debt) and specific issuers or securities. The goal of this approach is to seek higher yields while taking a risk-conscious approach. Risk management practices include managing the fund’s duration (which is a measurement of the price sensitivity of a bond or bond fund to changes in interest rates), while also focusing on striking a balance between (i) investing more heavily in certain sectors or issuers and (ii) diversifying the fund’s investments across the broader municipal market.Normally, at least 80% of the fund’s income will be exempt from federal income taxes. However, up to 20% of the fund’s income could be derived from securities subject to the alternative minimum tax. From time to time, the fund may invest a significant portion of its assets in sectors with special risks, such as health care, transportation, utilities, or private activity bonds. Principal Risks As with any fund, there is no guarantee that the fund will achieve its objective(s). The fund’s share price fluctuates, which means you could lose money by investing in the fund. The principal risks of investing in this fund, which may be even greater in bad or uncertain market conditions, are summarized as follows:Municipal securities The fund may be highly impacted by events tied to the overall municipal securities markets, which can be very volatile and significantly affected by unfavorable legislative or political developments and adverse changes in the financial conditions of municipal securities issuers and the global, national, and/or local economies. Income from municipal securities held by the fund could become taxable because of changes in tax laws or interpretations by taxing authorities, or noncompliant conduct of a state or municipality. Other changes in tax laws, including changes to individual or corporate tax rates, could alter the attractiveness and overall demand for municipal bonds. Certain sectors of the municipal bond market have special risks and could be affected by certain developments more significantly than the market as a whole. For example: health care can be negatively impacted by rising expenses and dependency on third party reimbursements; transportation can be negatively impacted by declining revenues or unexpectedly high construction or fuel costs; utilities are subject to governmental rate regulation; and private activity bonds (including industrial development bonds) rely on project revenues and the creditworthiness of the corporate user as opposed to governmental support. Investing significantly in municipal obligations backed by revenues of similar types of industries or projects may make the fund more susceptible to developments affecting those industries and projects. Market conditions The value of the fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of the fund’s holdings and markets generally, including political or regulatory developments, recessions, inflation, rapid interest rate changes, war, military conflict, or acts of terrorism, natural disasters, and outbreaks of infectious illnesses or other widespread public health issues such as the coronavirus pandemic and related governmental and public responses (including sanctions). Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns.Interest rates The prices of, and the income generated by, debt instruments held by the fund may be affected by changes in interest rates. A rise in interest rates typically causes the price of a fixed rate debt instrument to fall and its yield to rise. Conversely, a decline in interest rates typically causes the price of a fixed rate debt instrument to rise and the yield to fall. Generally, funds with longer weighted average maturities and durations carry greater interest rate risk. Changes in monetary policy made by central banks and/or governments, such as the discontinuation and replacement of benchmark rates, are likely to affect the interest rates or yields of the securities in which the fund invests.Callable bonds While a rise in interest rates is the principal source of interest rate risk for bond funds, falling rates bring the possibility that a bond may be “called,” or redeemed before maturity, and that the proceeds may need to be reinvested in lower-yielding securities.Credit quality An issuer of a debt instrument could suffer an adverse change in financial condition that results in a payment default (failure to make scheduled interest or principal payments), rating downgrade, or inability to meet a financial obligation. Securities that are rated below investment grade carry greater risk of default and should be considered speculative. Economic downturns often result in reduced levels of taxes collected and revenues earned by municipalities and insufficient funding to meet pension or health care obligations, which could lessen the overall financial strength of a municipality and increase the credit risk of the securities it issues. The fund’s credit risk is increased to the extent it invests in securities that are not backed by the taxing power of the municipal issuer.Liquidity The fund may not be able to sell a holding in a timely manner at a desired price. Reduced liquidity in the bond markets can result from a number of events, such as limited trading activity, reductions in bond inventory, and rapid or unexpected changes in interest rates. The secondary market for certain municipal bonds tends to be less developed and less liquid than many other bond markets. Less liquid markets could lead to greater price volatility and limit the fund’s ability to sell a holding at a suitable price.Sector exposure At times, the fund may have a significant portion of its assets invested in securities of issuers conducting business in a broadly related group of industries within the same economic sector. Issuers in the same economic sector may be similarly affected by economic or market events, making the fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly. Alternative minimum tax Although the fund seeks to distribute tax-exempt income, a portion of the fund’s otherwise tax-exempt dividends may be taxable to those shareholders subject to the federal alternative minimum tax.Active management The fund’s overall investment program and holdings selected by the fund’s investment adviser may underperform the broad markets, relevant indices, or other funds with similar objectives and investment strategies.Cybersecurity breaches The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the fund’s assets, customer data and confidential shareholder information, or other proprietary information. In addition, a cybersecurity breach could cause one of the fund’s service providers or financial intermediaries to suffer unauthorized data access, data corruption, or loss of operational functionality. The fund’s share price fluctuates, which means you could lose money by investing in the fund.
