Rowe Price Communications & Technology Fund, Inc. 2024-05-01 Communications & Technology Fund Investment Objective(s) The fund seeks to provide long-term capital growth. 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. Shareholder fees (fees paid directly from your investment) 20 0 Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0064 0.0064 0.0018 0.0004 0.0082 0.0068 -0.0005 0 0.0077 0.0068 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, that your investment has a 5% return each year, and that the fund’s operating expenses remain the same. The example also assumes that any current expense limitation arrangement remains in place for the period noted in the previous table; therefore, the figures have been adjusted to reflect fee waivers or expense reimbursements only in the periods for which the expense limitation arrangement is expected to continue. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 79 247 440 1000 69 218 379 847 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 33.9% of the average value of its portfolio. 0.339 Principal Investment Strategies The fund normally invests at least 80% of its net assets (including any borrowings for investment purposes) in securities of communications and technology companies. These companies can be involved in a variety of industries, including, but not limited to, Internet-related industries such as digital advertising, e-commerce and streaming services; media, including studios, publishers, music labels and advertising agencies; telecommunications services and infrastructure providers; payment networks; enterprise software and services; computer hardware; semiconductor design and manufacturing; and components and equipment. Stock selection is based on fundamental, bottom-up analysis that seeks to identify companies with good appreciation prospects. The portfolio manager may use both growth and value approaches to stock selection. When assessing opportunities among growth stocks, the portfolio manager generally seeks to identify companies with capable management, attractive business niches, sound financial and accounting practices, and a demonstrated ability to increase revenues, earnings, and cash flow consistently. In looking for value stocks, the portfolio manager will seek companies whose current stock prices appear undervalued in terms of earnings, projected cash flow, or asset value per share, and with growth potential temporarily unrecognized by the market. The portfolio manager also seeks to invest in companies whose stock prices may be temporarily depressed.The fund’s portfolio may hold stocks of either U.S. or non-U.S. companies, and may at times consist of a relatively small number of holdings. Although the fund typically invests a greater portion of its assets in U.S. stocks, there is no limit on the fund’s investments in non-U.S. securities.The fund may, to a limited extent, invest in privately held companies and companies that only recently began to trade publicly.The fund is “nondiversified,” meaning it may invest a greater portion of its assets in fewer issuers than is permissible for a “diversified” fund. Principal Risks The fund’s share price fluctuates, which means you could lose money by investing in the fund. Communications and technology companies: A fund that focuses its investments in specific industries or sectors is more susceptible to adverse developments affecting those industries and sectors than a more broadly diversified fund. Because the fund invests significantly in communications and technology companies, the fund may perform poorly during a downturn in the communications and technology industries. Communications and technology companies can be adversely affected by, among other things, changes in government regulations or increased government scrutiny; dependency on patent protection and intellectual property rights; intense competition; and rapid obsolescence of products and services due to product compatibility, technological innovations, or changing consumer preferences. Communications and technology companies may also be more susceptible than companies in other sectors to hacking attempts and potential theft of proprietary or consumer information, or disruptions in service, which could have a material adverse effect on their businesses. 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 economic, political, or regulatory developments, recessions, inflation, rapid interest rate changes, war, military conflict, 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. Private placements and IPOs: Investments in the stocks of privately held companies and in companies that only recently began to publicly trade, such as initial public offerings or IPOs, involve greater risks than investments in stocks of companies that have traded publicly on an exchange for extended time periods. There is significantly less information available about these companies’ business models, quality of management, earnings growth potential, and other criteria that are normally considered when evaluating the investment prospects of a company. Private placements and other restricted securities held by the fund are typically considered to be illiquid and tend to be difficult to value since there are no market prices and less overall financial information available. The adviser evaluates a variety of factors when assigning a value to these holdings, but the determination involves some degree of subjectivity and the value assigned for the fund may differ from the value assigned by other mutual funds holding the same security. Liquidity: A particular investment or an entire market segment may become less liquid or even illiquid, sometimes abruptly, which could limit the fund’s ability to purchase or sell holdings in a timely manner at a desired price. An inability to sell a portfolio holding can adversely affect the fund’s overall value or prevent the fund from being able to take advantage of other investment opportunities. Liquidity risk may be magnified during periods of substantial market volatility and unexpected episodes of illiquidity may limit the fund’s ability to pay redemption proceeds without selling holdings at an unfavorable time or at a suitable price. Large redemptions may also have a negative impact on the fund’s overall liquidity. Investing style: Because the fund may hold stocks with either growth or value characteristics, it could underperform other funds that take a strictly growth or value approach to investing when one style is currently in favor. Growth stocks tend to be more volatile than the overall stock market and can have sharp price declines as a result of earnings disappointments. Value stocks carry the risk that the market will not recognize their intrinsic value for a long time (or at all) or that they are actually appropriately priced at a low level. International investing: Non-U.S. securities tend to be more volatile and have lower overall liquidity than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. In addition, investments outside the U.S. are subject to settlement practices and regulatory and financial reporting standards that differ from those of the U.S. The risks of investing outside the U.S. are heightened for any investments in emerging markets, which are susceptible to greater volatility than investments in developed markets. 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. Stock investing: Stocks generally fluctuate in value more than bonds and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. The value of stocks held by the fund may decline due to general weakness or volatility in the stock markets in which the fund invests or because of factors that affect a particular company or industry. Nondiversification: As a nondiversified fund, the fund has the ability to invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. As a result, poor performance by a single issuer could adversely affect fund performance more than if the fund were invested in a larger number of issuers. The fund’s share price can be expected to fluctuate more than that of a similar fund that is more broadly diversified. Cybersecurity breaches: The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the fund’s assets, confidential 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.
