(a) Purchases of Class A shares in amounts of $1,000,000 or more, or by certain group retirement plans, may be subject to
a 1%, 1-year contingent deferred sales charge, or CDSC, which may be subject to waiver in certain circumstances.

------

(b) For Class C shares, the CDSC is 0% after the first year. Class C shares automatically convert to Class A
shares after eight years.

(c) Effective August 1, 2024, the Adviser has contractually agreed to waive 0.025% of its management fee from the Fund
until February 28, 2027. This waiver agreement may be terminated or changed only with the consent of the Board of Directors.

(d) The Adviser has contractually agreed to waive its management fees and/or bear certain expenses of the Fund to the extent
necessary to prevent total Fund operating expenses (excluding acquired fund fees and expenses other than the advisory fees of any AB Funds in which the Fund may invest, interest expense, taxes, extraordinary expenses, and brokerage commissions and
other transaction costs), on an annualized basis, from exceeding 0.90%, 1.65%, 0.65%, 0.65% and 0.65% of average daily net assets, respectively, for Class A, Class C, Advisor Class, Class I and Class Z shares. The agreement will remain in
effect until February 28, 2027 and may only be terminated or changed with the consent of the Fund's Board of Directors. In addition, the agreement will be automatically extended for one-year terms unless the Adviser provides notice of
termination to the Fund at least 60 days prior to the end of the period.

**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, that the Fund's operating expenses stay the same and that any fee waiver and/or expense limitation is in effect for only the first year. 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** | **Class Z** |
|  After 1 Year | $510 | $266 \* | $63 | $66 | $60 |
|  After 3 Years | $691 | $514 | $198 | $217 | $189 |
|  After 5 Years | $887 | $886 | $346 | $380 | $329 |
| After 10 Years | $1452 | $1730 | $774 | $855 | $738 |

---

\* 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 35% of the average value of its portfolio.

**PRINCIPAL STRATEGIES** 

The Fund invests primarily in a diversified portfolio of equity securities of U.S. companies. Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities. The Fund invests primarily in income-producing securities, targeting an investment in such securities of at least 65% of its total assets. The Fund seeks current income and capital growth from investments in a wide range of industries.

The Fund invests in companies that the Adviser determines to be undervalued, using the fundamental value approach of the Adviser. The fundamental value approach seeks to identify a universe of securities that are considered to be undervalued because they are attractively priced relative to their future earnings power and dividend-paying capability. In selecting securities for the Fund's portfolio, the Adviser uses fundamental and quantitative research to identify and invest in those companies whose long-term earnings power and dividend-paying capability are not reflected in the current market price of these securities.

The Adviser's fundamental analysis depends heavily upon its large internal research staff. The research staff of company and industry analysts covers a research universe drawn primarily from the S&P 500 Index. The Adviser typically projects a company's financial performance over a full economic cycle, including a trough and a peak. The Adviser's research staff focuses on the valuations implied by the current price, relative to the earnings the company will be generating five years from now, or "normalized" earnings, assuming average mid-economic cycle growth for the fifth year.

The Fund's management team and other senior investment professionals work in close collaboration to weigh each investment opportunity identified by the research staff relative to the entire portfolio and determine the timing and position size for purchases and sales. Analysts remain responsible for monitoring new developments that would affect the securities they cover. The team will generally sell a security when it no longer meets appropriate valuation criteria, although sales may be delayed when positive return trends are favorable.

The Fund may invest in securities of non-U.S. companies, but will limit its investments in any one non-U.S. country to no more than 15% of its net assets.

The Fund may enter into derivatives transactions, such as options, futures contracts, forwards, and swaps. The Fund may use options strategies involving the purchase and/or writing of various combinations of call and/or put options, including on individual securities and stock indices, futures contracts (including futures contracts on individual securities and stock indices) or shares of

------

exchange-traded funds ("ETFs"). These transactions may be used, for example, in an effort to earn extra income, to adjust exposure to individual securities or markets, or to protect all or a portion of the Fund's portfolio from a decline in value, sometimes within certain ranges.

The Fund may, at times, invest in shares of ETFs in lieu of making direct investments in equity securities. ETFs may provide more efficient and economical exposure to the type of companies and geographic locations in which the Fund seeks to invest than direct investments.

**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), terrorism, war, changing interest rate levels, the imposition of new or additional tariffs, 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.

• **Foreign (Non-U.S.) Risk:** Investments in securities of non-U.S. issuers may involve more risk than those of
U.S. issuers. These securities may fluctuate more widely in price and may be more difficult to trade due to adverse market, economic, political, regulatory or other factors.

• **Currency Risk:** Fluctuations in currency exchange rates may negatively affect the value of the Fund's
investments or reduce its returns.

• **Derivatives Risk:** Derivatives may be difficult to price or unwind and leveraged so that small changes may
produce disproportionate losses for the Fund. A short position in a derivative instrument involves the risk of a theoretically unlimited increase in the value of the underlying asset, reference rate or index, which could cause the Fund to suffer a
potentially unlimited loss. Derivatives, especially over-the-counter derivatives, are also subject to counterparty risk, which is the risk that the counterparty (the party on the other side of the transaction) on a derivative transaction will be
unable or unwilling to honor its contractual obligations to the Fund.

• **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.

• **Capital Gain Risk:** As of the date of the Fund's Prospectus, a substantial portion of the
Fund's net asset value is attributable to realized and/or net unrealized capital gains on portfolio securities. If the Fund realizes capital gains in excess of realized capital losses in any fiscal year, it generally expects to make capital
gain distributions to shareholders. You may receive distributions that are attributable to appreciation of portfolio securities that happened before you made your investment. Unless you purchase shares through a tax-advantaged account (such as an
IRA or 401(k) plan), these distributions will be taxable to you even though they economically represent a return of a portion of your investment. You should consult your tax professional about your investment in the Fund.

• **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, 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 <u>www.abfunds.com</u> (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.

\* After-tax returns:

– Are shown for Class A shares only and will vary for the other Classes of shares because these Classes have different expense ratios;

– Are estimates based on the highest historical individual federal marginal income tax rates, and do not reflect the impact of state and local taxes; actual after-tax returns depend on an individual investor's tax situation and are likely to differ from those shown; and

– Are not relevant to investors who hold fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.
