Investment Objective

The fund seeks to provide long-term capital growth by investing primarily in the common stocks of growth companies.

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold shares of the fund.

Fees and Expenses of the Fund’s I Class

Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment)
Management fees	0.64%
Distribution and service (12b-1) fees	0.00%
Other expenses	0.31%
Total annual fund operating expenses	0.95%
Fee waiver/expense reimbursement	(0.26)%a
Total annual fund operating expenses after fee waiver/expense reimbursement	0.69%a

aThrough April 30, 2018, T. Rowe Price Associates, Inc. has agreed to pay the operating expenses of the fund’s I Class excluding management fees; interest; expenses related to borrowings, taxes and brokerage; nonrecurring, extraordinary expenses; and acquired fund fees and expenses (“I Class Operating Expenses”), to the extent the I Class Operating Expenses exceed 0.05% of the class’ average daily net assets. Any expenses paid under this agreement are subject to reimbursement to T.  Rowe Price Associates, Inc. by the fund or class whenever the fund’s I Class Operating Expenses are below 0.05%. However, no reimbursement will be made more than three years after the payment of the I Class Operating Expenses or if such reimbursement would cause the fund’s I Class Operating Expenses to exceed 0.05%. The agreement may be terminated at any time beyond April 30, 2018, with approval by the fund’s Board of Directors.

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, that the fund’s operating expenses remain the same, and the expense limitation currently in place is not renewed. 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:

1 year	3 years	5 years	10 years
$70	$249	$473	$1,117

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 period December 17, 2015 through December 31, 2015, the fund’s portfolio turnover rate was 81.0% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment StrategiesThe fund invests primarily (at least 65% of its total assets) in common stocks of U.S. companies operating in those sectors of the economy that, in the view of the fund’s adviser are the fastest growing or have the greatest growth potential. The U.S. economy continues to evolve, in part because of the application of new technologies and scientific advances. Growing companies that are positioned to benefit from dynamic technological, social, medical, and business developments that help define the current U.S. economic landscape can be found across an array of industries. The fund’s allocation to industry sectors will generally reflect such factors as the overall revenue growth of the component companies in a sector and the sector’s contribution to U.S. gross domestic product from year to year, although the fund may at times invest significantly in stocks of technology companies.

Holdings range from large-cap to small-cap companies. In selecting stocks, we look for many characteristics, typically including, but not limited to:

·earnings growth rates that generally exceed that of the average company in the S&P 500 Stock Index;

·favorable company fundamentals, such as a strong balance sheet, sound business strategy, and promising competitive positioning;

·effective management; or

·stock valuations, such as price/earnings or price/cash flow ratios, that seem reasonable relative to the company’s prospects.

In pursuing its investment objective, the fund has the discretion to deviate from its normal investment criteria. These situations might arise when the fund’s adviser believes a security could increase in value for a variety of reasons, including an extraordinary corporate event, a new product introduction or innovation, a favorable competitive development, or a change in management.

While most assets will typically be invested in U.S. common stocks, the fund may invest in foreign stocks in keeping with the fund’s objectives.

The fund may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities.

Principal Risks As with any mutual fund, there is no guarantee that the fund will achieve its objective. 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 are summarized as follows:

Summary 3

Active management riskThe fund is subject to the risk that the investment adviser’s judgments about the attractiveness, value, or potential appreciation of the fund’s investments may prove to be incorrect. If the investments selected and strategies employed by the fund fail to produce the intended results, the fund could underperform in comparison to other funds with similar objectives and investment strategies.

Risks of U.S. 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 a stock in which the fund invests may decline due to general weakness in the U.S. stock market, such as when the U.S. financial markets decline, or because of factors that affect a particular company or industry.

Investment style risk Different investment styles tend to shift in and out of favor depending on market conditions and investor sentiment. The fund’s growth approach to investing could cause it to underperform other stock funds that employ a different investment style. Growth stocks tend to be more volatile than certain other types of stocks, and their prices may fluctuate more dramatically than the overall stock market. A stock with growth characteristics can have sharp price declines due to decreases in current or expected earnings and may lack dividends that can help cushion its share price in a declining market.

Market capitalization risk Because the fund may invest in companies of any size, its share price could be more volatile than a fund that invests only in large companies. Small- and medium-sized companies often have less experienced management, narrower product lines, more limited financial resources, and less publicly available information than larger companies. Larger companies may not be able to attain the high growth rates of successful smaller companies, especially during strong economic periods, and they may be less capable of responding quickly to competitive challenges and industry changes.

Industry risk To the extent the fund invests in specific industries or sectors, it may be more susceptible to developments affecting those industries and sectors. For example, the fund may at times have significant investments in technology companies, which could result in the fund performing poorly during a downturn in one or more of the industries that heavily impact technology companies. Technology companies can be adversely affected by, among other things, intense competition, earnings disappointments, and rapid obsolescence of products and services due to technological innovations or changing consumer preferences.

Foreign investing risk This is the risk that the fund’s investments in foreign securities may be adversely affected by local, political, social, and economic conditions overseas, greater volatility, reduced liquidity, or decreases in foreign currency values relative to the U.S. dollar.

Performance The New American Growth Fund—I Class incepted on December 17, 2015, and does not have a full calendar year of performance history. Performance for the class will be presented after the class has been in operation for one full calendar year. As a point of comparison, however, the following bar chart and table show calendar year returns and average annual total returns for the existing Investor Class of the New American Growth Fund (“Investor Class”). Because the New American Growth Fund—I Class is expected to have lower expenses than the Investor Class, its performance, had it existed over the periods shown, would have been higher. The Investor Class and the New American Growth Fund—I Class share the same portfolio. The bar chart and table provide some indication of the risks of investing in the fund by showing how much returns can differ from year to year and how the Investor Class’ average annual returns for certain periods compare with the returns of a relevant broad-based market index, as well as with the returns of one or more other comparative indexes that have investment characteristics similar to those of the fund.

The fund can also experience short-term performance swings, as shown by the best and worst calendar quarter returns during the years depicted for the Investor Class.

Performance information represents only past performance (before and after taxes) and does not necessarily indicate future results.

In addition, the average annual total returns table shows hypothetical after-tax returns to demonstrate how taxes paid by a shareholder may influence returns. 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. After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as a 401(k) account or individual retirement

account. In some cases, the figure shown for “returns after taxes on distributions and sale of fund shares” may be higher than the figure shown for “returns before taxes” because the calculations assume the investor received a tax deduction for any loss incurred on the sale of shares.
