The performance shown above represents past performance and does not guarantee future results. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by visiting www.abfunds.com. The investment return and principal value of an investment in the Portfolio will fluctuate, so that your shares, when redeemed, may be worth more or less than their original cost. Advisor Class shares have no front-end or contingent deferred sales charges; however, when purchased through a financial advisor, additional fees may apply. Returns for other share classes will vary due to different charges and expenses. Performance assumes reinvestment of distributions and does not account for taxes. Please keep in mind that high, double-digit returns are highly unusual and cannot be sustained. Investors should also be aware that these returns were primarily achieved during favorable market conditions. †This reflects the Advisor’s contractual waiver of a portion of its advisory fee and/or reimbursement of a portion of the Fund’s operating expenses. This waiver extends through October 31, 2018, and may be extended by the Advisor for additional one-year terms. Absent reimbursements or waivers, performance would have been lower. Net expense is actual cost paid by investor, displayed as a percentage of the Fund’s net assets. The Fund’s Advisor Class share inception date is December 12, 2012 Relative to the Morningstar US Fund Long/Short Equity category. Funds within the category generally have similar investment objectives, although some may have different investment policies. Source: Morningstar, S&P and AB For home office use only.

Investors should consider the investment objectives, risks, charges and expenses of the Fund/Portfolio carefully before investing. For copies of our prospectus or summary prospectus, which contain this and other information, visit us online at www.abfunds.com or contact your AB representative. Please read the prospectus and/or summary prospectus carefully before investing.

A Word About Risk Market Risk: The market values of the Portfolio’s holdings rise and fall from day to day, so investments may lose value. Capitalization-Size Risk (Small/Mid): Small- and mid-cap stocks are often more volatile than large-cap stocks—smaller companies generally face higher risks due to their limited product lines, markets and financial resources. Foreign (Non-US) Risk: Non-US securities may be more volatile because of the political, regulatory, market and economic uncertainties associated with such securities. Fluctuations in currency exchange rates may negatively affect the value of the investment or reduce returns. These risks are magnified in emerging or developing markets. Derivatives Risk: Investing in instruments such as options, futures, forwards or swaps can be riskier than traditional investments, and may be more volatile, especially in a down market.

The specific securities identified and described in this presentation do not represent all of the securities purchased, sold or recommended for the portfolio, and it should not be assumed that investments in the securities identified were or will be profitable.
