Examples

The Examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Examples assume 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 Examples also assume that your investment has a 5% return each year and that the Fund's operating expenses stay the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

		Class A			Class C			Advisor Class			Class I
After 1 Year		$	569			$	327	*		$	125			$	122
After 3 Years		$	873			$	700			$	390			$	381
After 5 Years		$	1,199			$	1,200			$	676			$	660
After 10 Years		$	2,118			$	2,383			$	1,489			$	1,455

*	If you did not redeem your shares at the end of the period, your expenses would be decreased by approximately $100.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys or 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 transaction costs, which are not reflected in the Annual Fund Operating Expenses or in the Examples, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 171% of the average value of its portfolio.

PRINCIPAL STRATEGIES

Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of U.S. companies. For purposes of this policy, equity securities include common stock, preferred stock and derivatives related to common and preferred stocks.

The Adviser selects investments for the Fund through an intensive "bottom-up" approach that places an emphasis on companies that are engaged in business activities with solid long-term growth potential and operating in industries with high barriers to entry, that have strong cash flows and other financial metrics, and that have transparent financial statements and business models. The Adviser also evaluates the quality of company management based on a series of criteria, including: (1) management's focus on shareholder returns, such as through a demonstrated commitment to dividends and dividend growth, share buybacks or other shareholder-friendly corporate actions; (2) management's employment of conservative accounting methodologies; (3) management incentives, such as direct equity ownership; and (4) management accessibility. The Adviser seeks to identify companies where events or catalysts may drive the company's share price higher, such as earnings and/or revenue growth above consensus forecasts, potential market recognition of undervaluation or overstated market-risk discount, or the institution of shareholder-focused changes discussed in the preceding sentence. In light of this catalyst-focused approach, the Adviser expects to engage in active and frequent trading for the Fund.

The Adviser may reduce or eliminate the Fund's holdings in a company's securities for a number of reasons, including if its evaluation of the above factors changes adversely, if the anticipated events or catalysts do not occur or do not affect the price of the securities as expected, or if the anticipated events or catalysts do occur and cause the securities to be, in the Adviser's view, overvalued or fully valued. At any given time the Fund may emphasize growth stocks over value stocks, or vice versa.

The Fund's investments will be focused on securities of companies with large and medium market capitalizations, but it may also invest in securities of small-capitalization companies. The Fund may invest in non-U.S. companies, but will limit its investments in such companies to no more than 10% of its net assets. The Fund may purchase securities in initial public offerings ("IPOs") and expects to do so on a regular basis.

PRINCIPAL RISKS

•

Market Risk: The value of the Fund's assets will fluctuate as the market or markets in which the Fund invests fluctuate. The value of the Fund's investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events, including public health crises (including the occurrence of a contagious disease or illness) and regional and global conflicts, that affect large portions of the market. It includes the risk that a particular style of investing may be underperforming the market generally.

•

Sector Risk: The Fund may have more risk because it may invest to a significant extent in one or more particular market sectors, such as the information technology sector. To the extent it does so, market or economic factors affecting the relevant sector(s) could have a major effect on the value of the Fund's investments.

S-2

•

Capitalization Risk: Investments in small- and mid-capitalization companies may be more volatile than investments in large-capitalization companies. Investments in these companies may have additional risks because these companies may have limited product lines, markets or financial resources.

•

Active Trading Risk: The Fund expects to engage in active and frequent trading of its portfolio securities and its portfolio turnover rate may greatly exceed 100%. A higher rate of portfolio turnover increases transaction costs, which may negatively affect the Fund's return. In addition, a high rate of portfolio turnover may result in substantial short-term gains, which may have adverse tax consequences for Fund shareholders.

•

IPO Risk: Securities purchased in an IPO may be subject to substantial price volatility due to one or more factors such as unseasoned trading in the securities, the lack of investor knowledge of the issuer, the lack of an operating history of the issuer, and the dependence of the issuer on key personnel, suppliers or a limited number of customers.

•

Management Risk: The Fund is subject to management risk because it is an actively-managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Fund, but there is no guarantee that its techniques will produce the intended results. Some of these techniques may incorporate, or rely upon, quantitative models, but there is no guarantee that these models will generate accurate forecasts, reduce risk or otherwise perform as expected.

As with all investments, you may lose money by investing in the Fund.

BAR CHART AND PERFORMANCE INFORMATION

The bar chart and performance information provide an indication of the historical risk of an investment in the Fund by showing:

•

how the Fund's performance changed from year to year over ten years; and

•

how the Fund's average annual returns for one, five and ten years compare to those of a broad-based securities market index.

You may obtain updated performance information on the Fund's website at www.abfunds.com (click on "Investments-Mutual Funds").

The Fund's past performance before and after taxes, of course, does not necessarily indicate how it will perform in the future.

Bar Chart

The annual returns in the bar chart are for the Fund's Class A shares and do not reflect sales loads. If sales loads were reflected, returns would be less than those shown. Through September 30, 2024, the year-to-date unannualized return for Class A shares was 23.25%.

During the period shown in the bar chart, the Fund's:

Best Quarter was up 17.40%, 2nd quarter, 2020; and Worst Quarter was down -19.59%, 1st quarter, 2020.
