Also includes the impact of a non-recurring refund for overbilling of prior years’ custody out of pocket fees, which enhanced performance for the six- and 12-month periods ended November 30, 2017, by 0.00% and 0.01%, respectively. Includes the impact of proceeds received and credited to the Fund in connection with a third party regulatory settlement, which enhanced performance for the six- and 12-month periods ended November 30, 2017, by 0.02% and 0.02%, respectively.

2 Effective January 31, 2009, Class B shares are no longer available for purchase to new investors. Please see Note A for additional information.

3 Please note that these share classes are for investors purchasing shares through accounts established under certain fee-based programs sponsored and maintained by certain broker-dealers and financial intermediaries, institutional pension plans and/or investment advisory clients of, and certain other persons associated with, the Adviser and its affiliates or the Fund.

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.

INVESTMENT RESULTS

The table above shows the Fund’s performance compared to its primary benchmark, the Standard & Poor’s (“S&P”) 500 Index, and the Russell 1000 Value Index for the six- and 12-month periods ended November 30, 2017.

2    ^|    AB CORE OPPORTUNITIES FUND abfunds.com

For the 12-month period, Class B, Class C and Class R shares underperformed the primary benchmark, while all other share classes outperformed, before sales charges. All class shares outperformed the Russell 1000 Value Index. Security selection contributed, specifically in the Fund’s health care, consumer staples, industrials, technology and real estate holdings, relative to the benchmark. An underweight position in energy and telecommunications, and an overweight in technology, contributed. Stock selection in the energy and consumer discretionary sectors detracted from performance. Sector selection detracted in part due to an underweight in the utilities sector.

For the six-month period, all share classes of the Fund outperformed the primary benchmark and the Russell 1000 Value Index, before sales charges. The Fund’s health care, industrials and consumer staples holdings contributed to performance, while energy and consumer discretionary holdings detracted. From a sector standpoint, underweight positions in the consumer staples and telecommunications sectors contributed. An underweight in the financials sector detracted from performance.

The Fund did not utilize derivatives during either period.

MARKET REVIEW AND INVESTMENT STRATEGY

US equities posted impressive gains over the 12-month period ended November 30, 2017, rallying after Donald Trump was elected president, and excitement regarding his pro-growth agenda gained momentum. Strong global economic data bolstered positive market sentiment. Growth stocks outperformed value, and large-cap stocks outperformed small-caps, in terms of style. Geopolitical tensions and a significant decline in the price of oil weighed on the market midperiod. Corporate earnings generally surprised to the upside and the price of oil later rebounded, pushing stocks higher, especially in emerging markets. Renewed discussion and momentum behind US corporate tax reform near the end of the period propelled equities to all-time highs. In June, the US Federal Reserve (the “Fed”) raised rates for the third consecutive quarter, as expected. In October, the Fed began its balance sheet reduction program. Late in the period, President Trump’s appointment of the next Fed chair was met with enthusiasm by markets.

The Fund’s investment philosophy is focused on identifying companies that meet the criteria of the Fund’s Senior Investment Management Team: healthy balance sheets, competitive advantages, strong cash-flow generation, transparent business models and sustainable growth. The Fund is conservatively positioned in an uncertain environment, with a bias toward companies demonstrating high profitability and dividend growth.

INVESTMENT POLICIES

The Fund invests primarily in the equity securities of US companies that the Adviser believes are undervalued. The Adviser believes that,

over time, a company’s stock price will come to reflect its intrinsic economic value. The Fund may invest in companies of any size and in any industry.

The Adviser depends heavily upon the fundamental analysis and research of its large internal research staff in making investment decisions for the Fund. The research staff follows a primary research universe of approximately 500, largely US, companies. In determining a company’s intrinsic economic value, the Adviser takes into account many fundamental and financial factors that it believes bear on the company’s ability to perform in the future, including earnings growth, prospective cash flows, dividend growth and growth in book value. The Adviser then ranks each of the companies in its research universe in the relative order of disparity between their intrinsic economic values and their current stock prices, with companies with the greatest disparities receiving the highest rankings (i.e., being considered the most undervalued). The Adviser anticipates that the Fund’s portfolio normally will include companies ranking in the top three deciles of the Adviser’s valuation model.

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.

DISCLOSURES AND RISKS

Benchmark Disclosure

The S&P^® 500 Index and the Russell 1000^® Value Index are unmanaged and do not reflect fees and expenses associated with the active management of a mutual fund portfolio. The S&P 500 Index includes 500 US stocks and is a common representation of the performance of the overall US stock market. The Russell 1000 Value Index represents the performance of 1,000 large-cap value companies within the US. An investor cannot invest directly in an index or average, and their results are not indicative of the performance for any specific investment, including the Fund.

A Word About Risk

Market Risk: The value of the Fund’s investments will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events that affect large portions of the market. It includes the risk that a particular style of investing, such as the Fund’s value approach, may be underperforming the market generally.

Focused Portfolio Risk: Investments in a limited number of companies may have more risk because changes in the value of a single security may have a more significant effect, either negative or positive, on the Fund’s net asset value (“NAV”).

Foreign (Non-US) Risk: Investments in securities of non-US issuers may involve more risk than those of US issuers. These securities may fluctuate more widely in price and may be less liquid 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 illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses for the Fund, and may be subject to counterparty risk to a greater degree than more traditional investments.

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.

These risks are fully discussed in the Fund’s prospectus. As with all investments, you may lose money by investing in the Fund.

An Important Note About Historical Performance

The investment return and principal value of an investment in the Fund will fluctuate, so that shares, when redeemed, may be worth more or less than their original cost. Performance shown in this report 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.

All fees and expenses related to the operation of the Fund have been deducted. NAV returns do not reflect sales charges; if sales charges were reflected, the Fund’s quoted performance would be lower. SEC returns reflect the applicable sales charges for each share class: a 4.25% maximum front-end sales charge for Class A shares; the applicable contingent deferred sales charge for Class B shares (4% year 1, 3% year 2, 2% year 3, 1% year 4) and a 1% 1-year contingent deferred sales charge for Class C shares. Returns for the different share classes will vary due to different expenses associated with each class. Performance assumes reinvestment of distributions and does not account for taxes.

EXPENSE EXAMPLE

(unaudited)

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, contingent deferred sales charges on redemptions and (2) ongoing costs, including management fees; distribution (12b-l) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period as indicated below.

Actual Expenses

The table below provides information about actual account values and actual expenses. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The table below also provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed annual rate of return of 5% before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds by comparing this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), or contingent deferred sales charges on redemptions. Therefore, the hypothetical example is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

* Expenses are equal to the classes’ annualized expense ratios multiplied by the average account value over the period, multiplied by 183/365 (to reflect the one-half year period).

** Assumes 5% annual return before expenses.

⁺  In connection with the Fund’s investments in affiliated/unaffiliated underlying portfolios, the Fund incurs no direct expenses, but bears proportionate shares of the fees and expenses (i.e., operating, administrative and investment advisory fees) of the affiliated/unaffiliated underlying portfolios. The Adviser has contractually agreed to waive its fees from the Fund in an amount equal to the Fund’s pro rata share of certain acquired fund fees and expenses of the affiliated underlying portfolios. The Fund’s total expenses are equal to the classes’ annualized expense ratio plus the Fund’s pro rata share of the weighted average expense ratio of the affiliated/unaffiliated underlying portfolios in which it invests, multiplied by the average account value over the period, multiplied by 183/365 (to reflect the one-half year period).

NOTES TO FINANCIAL STATEMENTS

November 30, 2017

NOTE A

Significant Accounting Policies

AB Core Opportunities Fund, Inc. (the “Fund”), organized as a Maryland corporation on July 6, 1999, is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The Fund offers Class A, Class B, Class C, Advisor Class, Class R, Class K, Class I and Class Z shares. Class T shares have been authorized but currently are not offered. Class A shares are sold with a front-end sales charge of up to 4.25% for purchases not exceeding $1,000,000. With respect to purchases of $1,000,000 or more, Class A shares redeemed within one year of purchase may be subject to a contingent deferred sales charge of 1%. Class B shares are currently sold with a contingent deferred sales charge which declines from 4% to zero depending on the period of time the shares are held. Effective January 31, 2009, sales of Class B shares of the Fund to new investors were suspended. Class B shares will only be issued (i) upon the exchange of Class B shares from another AB mutual fund, (ii) for purposes of dividend reinvestment, (iii) through the Fund’s Automatic Investment Program (the “Program”) for accounts that established the Program prior to January 31, 2009, and (iv) for purchases of additional shares by Class B shareholders as of January 31, 2009. The ability to establish a new Program for accounts containing Class B shares was suspended as of January 31, 2009. Class B shares will automatically convert to Class A shares eight years after the end of the calendar month of purchase. Class C shares are subject to a contingent deferred sales charge of 1% on redemptions made within the first year after purchase, and 0% after the first year of purchase. Effective April 10, 2017, Class C shares will automatically convert to Class A shares ten years after the end of the calendar month of purchase. Class R and Class K shares are sold without an initial or contingent deferred sales charge. Advisor Class, Class I and Class Z shares are sold without an initial or contingent deferred sales charge and are not subject to ongoing distribution expenses. All nine classes of shares have identical voting, dividend, liquidation and other rights, except that the classes bear different distribution and transfer agency expenses. Each class has exclusive voting rights with respect to its distribution plan. The financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) which require management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements and amounts of income and expenses during the reporting period. Actual results could differ from those estimates. The Fund is an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies. The following is a summary of significant accounting policies followed by the Fund.

NOTES TO FINANCIAL STATEMENTS (continued)

1. Security Valuation

Portfolio securities are valued at their current market value determined on the basis of market quotations or, if market quotations are not readily available or are deemed unreliable, at “fair value” as determined in accordance with procedures established by and under the general supervision of the Fund’s Board of Directors (the “Board”).

In general, the market values of securities which are readily available and deemed reliable are determined as follows: securities listed on a national securities exchange (other than securities listed on the NASDAQ Stock Market, Inc. (“NASDAQ”)) or on a foreign securities exchange are valued at the last sale price at the close of the exchange or foreign securities exchange. If there has been no sale on such day, the securities are valued at the last traded price from the previous day. Securities listed on more than one exchange are valued by reference to the principal exchange on which the securities are traded; securities listed only on NASDAQ are valued in accordance with the NASDAQ Official Closing Price; listed or over the counter (“OTC”) market put or call options are valued at the mid level between the current bid and ask prices. If either a current bid or current ask price is unavailable, AllianceBernstein L.P. (the “Adviser”) will have discretion to determine the best valuation (e.g., last trade price in the case of listed options); open futures are valued using the closing settlement price or, in the absence of such a price, the most recent quoted bid price. If there are no quotations available for the day of valuation, the last available closing settlement price is used; U.S. Government securities and any other debt instruments having 60 days or less remaining until maturity are generally valued at market by an independent pricing vendor, if a market price is available. If a market price is not available, the securities are valued at amortized cost. This methodology is commonly used for short-term securities that have an original maturity of 60 days or less, as well as short-term securities that had an original term to maturity that exceeded 60 days. In instances when amortized cost is utilized, the Valuation Committee (the “Committee”) must reasonably conclude that the utilization of amortized cost is approximately the same as the fair value of the security. Such factors the Committee will consider include, but are not limited to, an impairment of the creditworthiness of the issuer or material changes in interest rates. Fixed-income securities, including mortgage-backed and asset-backed securities, may be valued on the basis of prices provided by a pricing service or at a price obtained from one or more of the major broker-dealers. In cases where broker-dealer quotes are obtained, the Adviser may establish procedures whereby changes in market yields or spreads are used to adjust, on a daily basis, a recently obtained quoted price on a security. Swaps and other derivatives are valued daily, primarily using independent pricing services, independent pricing models using market inputs, as well as third party broker-dealers or counterparties. Open end

22    ^|    AB CORE OPPORTUNITIES FUND abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

mutual funds are valued at the closing net asset value per share, while exchange traded funds are valued at the closing market price per share.

Securities for which market quotations are not readily available (including restricted securities) or are deemed unreliable are valued at fair value as deemed appropriate by the Adviser. Factors considered in making this determination may include, but are not limited to, information obtained by contacting the issuer, analysts, analysis of the issuer’s financial statements or other available documents. In addition, the Fund may use fair value pricing for securities primarily traded in non-U.S. markets because most foreign markets close well before the Fund values its securities at 4:00 p.m., Eastern Time. The earlier close of these foreign markets gives rise to the possibility that significant events, including broad market moves, may have occurred in the interim and may materially affect the value of those securities. To account for this, the Fund generally values many of its foreign equity securities using fair value prices based on third party vendor modeling tools to the extent available.

2. Fair Value Measurements

In accordance with U.S. GAAP regarding fair value measurements, fair value is defined as the price that the Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a framework for measuring fair value, and a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability (including those valued based on their market values as described in Note A.1 above). Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset or liability. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Fund. Unobservable inputs reflect the Fund’s own assumptions about the assumptions that market participants would use in pricing the asset or liability based on the best information available in the circumstances. Each investment is assigned a level based upon the observability of the inputs which are significant to the overall valuation. The three-tier hierarchy of inputs is summarized below.

• Level 1—quoted prices in active markets for identical investments

• Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

• Level 3—significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

abfunds.com AB CORE OPPORTUNITIES FUND    ^|    23

NOTES TO FINANCIAL STATEMENTS (continued)

Where readily available market prices or relevant bid prices are not available for certain equity investments, such investments may be valued based on similar publicly traded investments, movements in relevant indices since last available prices or based upon underlying company fundamentals and comparable company data (such as multiples to earnings or other multiples to equity). Where an investment is valued using an observable input, such as another publicly traded security, the investment will be classified as Level 2. If management determines that an adjustment is appropriate based on restrictions on resale, illiquidity or uncertainty, and such adjustment is a significant component of the valuation, the investment will be classified as Level 3. An investment will also be classified as Level 3 where management uses company fundamentals and other significant inputs to determine the valuation.

The following table summarizes the valuation of the Fund’s investments by the above fair value hierarchy levels as of November 30, 2017:

(a) See Portfolio of Investments for sector classifications.

(b) Other financial instruments are derivative instruments, such as futures, forwards and swaps, which are valued at the unrealized appreciation/(depreciation) on the instrument. Other financial instruments may also include swaps with upfront premiums, options written and swaptions written which are valued at market value.

(c) There were no transfers between any levels during the reporting period.

The Fund recognizes all transfers between levels of the fair value hierarchy assuming the financial instruments were transferred at the beginning of the reporting period.

The Adviser established the Committee to oversee the pricing and valuation of all securities held in the Fund. The Committee operates under pricing and valuation policies and procedures established by the Adviser and approved by the Board, including pricing policies which set forth the mechanisms and processes to be employed on a daily basis to implement these policies and procedures. In particular, the pricing policies describe how to determine market quotations for securities and other instruments. The Committee’s responsibilities include: 1) fair value and liquidity determinations (and oversight of any third parties to whom any responsibility for

24    ^|    AB CORE OPPORTUNITIES FUND abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

fair value and liquidity determinations is delegated), and 2) regular monitoring of the Adviser’s pricing and valuation policies and procedures and modification or enhancement of these policies and procedures (or recommendation of the modification of these policies and procedures) as the Committee believes appropriate.

The Committee is also responsible for monitoring the implementation of the pricing policies by the Adviser’s Pricing Group (the “Pricing Group”) and any third party which performs certain pricing functions in accordance with the pricing policies. The Pricing Group is responsible for the oversight of the third party on a day-to-day basis. The Committee and the Pricing Group perform a series of activities to provide reasonable assurance of the accuracy of prices including: 1) periodic vendor due diligence meetings, review of methodologies, new developments and processes at vendors, 2) daily comparison of security valuation versus prior day for all securities that exceeded established thresholds, and 3) daily review of unpriced, stale, and variance reports with exceptions reviewed by senior management and the Committee.

In addition, several processes outside of the pricing process are used to monitor valuation issues including: 1) performance and performance attribution reports are monitored for anomalous impacts based upon benchmark performance, and 2) portfolio managers review all portfolios for performance and analytics (which are generated using the Adviser’s prices).

3. Currency Translation

Assets and liabilities denominated in foreign currencies and commitments under forward currency exchange contracts are translated into U.S. dollars at the mean of the quoted bid and ask prices of such currencies against the U.S. dollar. Purchases and sales of portfolio securities are translated into U.S. dollars at the rates of exchange prevailing when such securities were acquired or sold. Income and expenses are translated into U.S. dollars at rates of exchange prevailing when accrued.

Net realized gain or loss on foreign currency transactions represents foreign exchange gains and losses from sales and maturities of foreign fixed income investments, holding of foreign currencies, currency gains or losses realized between the trade and settlement dates on foreign investment transactions, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded on the Fund’s books and the U.S. dollar equivalent amounts actually received or paid. Net unrealized currency gains and losses from valuing foreign currency denominated assets and liabilities at period end exchange rates are reflected as a component of net unrealized appreciation or depreciation of foreign currency denominated assets and liabilities.

4. Taxes

It is the Fund’s policy to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its investment company taxable income and net realized gains, if any, to shareholders. Therefore, no provisions for federal income or excise taxes are required. The Fund may be subject to taxes imposed by countries in which it invests. Such taxes are generally based on income and/or capital gains earned or repatriated. Taxes are accrued and applied to net investment income, net realized gains and net unrealized appreciation/depreciation as such income and/or gains are earned.

In accordance with U.S. GAAP requirements regarding accounting for uncertainties in income taxes, management has analyzed the Fund’s tax positions taken or expected to be taken on federal and state income tax returns for all open tax years (the current and the prior three tax years) and has concluded that no provision for income tax is required in the Fund’s financial statements.

5. Investment Income and Investment Transactions

Dividend income is recorded on the ex-dividend date or as soon as the Fund is informed of the dividend. Interest income is accrued daily. Investment transactions are accounted for on the date the securities are purchased or sold. Investment gains or losses are determined on the identified cost basis. The Fund amortizes premiums and accretes discounts as adjustments to interest income.

6. Class Allocations

All income earned and expenses incurred by the Fund are borne on a pro-rata basis by each outstanding class of shares, based on the proportionate interest in the Fund represented by the net assets of such class, except for class specific expenses which are allocated to the respective class. Realized and unrealized gains and losses are allocated among the various share classes based on respective net assets.

7. Dividends and Distributions

Dividends and distributions to shareholders, if any, are recorded on the ex-dividend date. Income dividends and capital gains distributions are determined in accordance with federal tax regulations and may differ from those determined in accordance with U.S. GAAP. To the extent these differences are permanent, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require such reclassification.

Advisory Fee and Other Transactions with Affiliates

Under the terms of the investment advisory agreement, the Fund pays the Adviser an advisory fee at an annual rate of .55% of the first $2.5 billion, .45% of the next $2.5 billion and .40% in excess of $5 billion, of the Fund’s average daily net assets. The fee is accrued daily and paid monthly. As of July 1, 2013 (effective October 15, 2013 with respect to Class Z shares), the Adviser has agreed to waive its fees and bear certain expenses to the extent necessary to limit total operating expenses (excluding acquired fund fees and expenses other than the advisory fees of any AB mutual funds in which the Fund may invest, interest expense, taxes, extraordinary expenses, and brokerage commissions and other transaction costs) on an annual basis to 1.15%, 1.90%, 1.90%, .90%, 1.40%, 1.15%, .90% and .90% of the daily average net assets for the Class A, Class B, Class C, Advisor Class, Class R, Class K, Class I and Class Z shares, respectively (the “Expense Caps”). Effective February 29, 2016, the Expense Cap for the Class A shares was reduced from 1.20% to 1.15% of the daily average net assets. The Expense Caps will extend through March 1, 2018 and then may be extended by the Adviser for additional one year terms. For the year ended November 30, 2017, such reimbursement waivers amounted to $5,206.

Pursuant to the investment advisory agreement, the Fund may reimburse the Adviser for certain legal and accounting services provided to the Fund by the Adviser. For the year ended November 30, 2017, the reimbursement for such services amounted to $59,048.

The Fund compensates AllianceBernstein Investor Services, Inc. (“ABIS”), a wholly-owned subsidiary of the Adviser, under a Transfer Agency Agreement for providing personnel and facilities to perform transfer agency services for the Fund. ABIS may make payments to intermediaries that provide omnibus account services, sub-accounting services and/or networking services. Such compensation retained by ABIS amounted to $122,330 for the year ended November 30, 2017.

AllianceBernstein Investments, Inc. (the “Distributor”), a wholly-owned subsidiary of the Adviser, serves as the distributor of the Fund’s shares. The Distributor has advised the Fund that it has retained front-end sales charges of $8,913 from the sale of Class A shares and received $5,101, $397 and $2,276 in contingent deferred sales charges imposed upon redemptions by shareholders of Class A, Class B and Class C shares, respectively, for the year ended November 30, 2017.

The Fund may invest in AB Government Money Market Portfolio (the “Government Money Market Portfolio”) which has a contractual annual

NOTES TO FINANCIAL STATEMENTS (continued)

advisory fee rate of .20% of the portfolio’s average daily net assets and bears its own expenses. In connection with the investment by the Fund in the Government Money Market Portfolio, the Adviser has contractually agreed to waive its advisory fee from the Fund in an amount equal to the Fund’ pro rata share of the effective advisory fees of Government Money Market Portfolio, as borne indirectly by the Fund as an acquired fund fee and expense. For the year ended November 30, 2017, such waiver amounted to $85,779.

A summary of the Fund’s transactions in AB mutual funds for the year ended November 30, 2017 is as follows:

Fund	Market Value 11/30/16 (000)		Purchases at Cost (000)		Sales Proceeds (000)		Market Value 11/30/17 (000)		Dividend Income (000)

NOTE C

Distribution Services Agreement

The Fund has adopted a Distribution Services Agreement (the “Agreement”) pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under the Agreement, the Fund pays distribution and servicing fees to the Distributor at an annual rate of up to .30% of the Fund’s average daily net assets attributable to Class A shares, 1% of the Fund’s average daily net assets attributable to both Class B and Class C shares, .50% of the Fund’s average daily net assets attributable to Class R shares and .25% of the Fund’s average daily net assets attributable to Class K shares. There are no distribution and servicing fees on the Advisor Class, Class I and Class Z shares. As of November 1, 2007, with respect to Class B shares, payments to the Distributor are voluntarily being limited to .40% of the average daily net assets attributable to Class B shares. For the year ended November 30, 2017, such waiver amounted to $10,217. Effective

28    ^|    AB CORE OPPORTUNITIES FUND abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

February 29, 2016, payments under the Agreement in respect of Class A shares are limited to an annual rate of .25% of Class A shares’ average daily net assets. The fees are accrued daily and paid monthly. The Agreement provides that the Distributor will use such payments in their entirety for distribution assistance and promotional activities. Since the commencement of the Fund’s operations, the Distributor has incurred expenses in excess of the distribution costs reimbursed by the Fund in the amounts of $89,275 $1,989,007, $235,543 and $67,680 for Class B, Class C, Class R and Class K shares, respectively. While such costs may be recovered from the Fund in future periods so long as the Agreement is in effect, the rate of the distribution and servicing fees payable under the Agreement may not be increased without a shareholder vote. In accordance with the Agreement, there is no provision for recovery of unreimbursed distribution costs incurred by the Distributor beyond the current fiscal year for Class A shares. The Agreement also provides that the Adviser may use its own resources to finance the distribution of the Fund’s shares.

NOTE D

Investment Transactions

Purchases and sales of investment securities (excluding short-term investments) for the year ended November 30, 2017 were as follows:

	Purchases			Sales
Investment securities (excluding U.S. government securities)	$	239,254,299		$	229,377,037
U.S. government securities		– 0	–		– 0	–

The cost of investments for federal income tax purposes, gross unrealized appreciation and unrealized depreciation are as follows:

Gross unrealized appreciation	$	49,164,189
Gross unrealized depreciation		(1,270,559	)
Net unrealized appreciation	$	47,893,630

1. Derivative Financial Instruments

The Fund may use derivatives in an effort to earn income and enhance returns, to replace more traditional direct investments, to obtain exposure to otherwise inaccessible markets (collectively, “investment purposes”), or to hedge or adjust the risk profile of its portfolio.

The Fund did not engage in derivatives transactions for the year ended November 30, 2017.

abfunds.com AB CORE OPPORTUNITIES FUND    ^|    29

NOTES TO FINANCIAL STATEMENTS (continued)

2. Currency Transactions

The Fund may invest in non-U.S. Dollar-denominated securities on a currency hedged or unhedged basis. The Fund may seek investment opportunities by taking long or short positions in currencies through the use of currency-related derivatives, including futures and options on futures, swaps, and other options. The Fund may enter into transactions for investment opportunities when it anticipates that a foreign currency will appreciate or depreciate in value but securities denominated in that currency are not held by the Fund and do not present attractive investment opportunities. Such transactions may also be used when the Adviser believes that it may be more efficient than a direct investment in a foreign currency-denominated security. The Fund may also conduct currency exchange contracts on a spot basis (i.e., for cash at the spot rate prevailing in the currency exchange market for buying or selling currencies).

NOTE E

Securities Lending

The Fund may enter into securities lending transactions. Under the Fund’s securities lending program, all loans of securities will be collateralized continually by cash. The Fund will be compensated for the loan from a portion of the net return from the income earned on cash collateral after a rebate is paid to the borrower (in some cases, this rebate may be a “negative rebate” or fee paid by the borrower to the Fund in connection with the loan), and payments are made for fees of the securities lending agent and for certain other administrative expenses. It is the policy of the Fund to receive collateral consisting of cash in an amount exceeding the value of the securities loaned. The Fund will have the right to call a loan and obtain the securities loaned at any time on notice to the borrower within the normal and customary settlement time for the securities. While the securities are on loan, the borrower is obligated to pay the Fund amounts equal to any income or other distributions from the securities. The Fund will not be able to exercise voting rights with respect to any securities during the existence of a loan, but will have the right to regain ownership of loaned securities in order to exercise voting or other ownership rights. The lending agent has agreed to indemnify the Fund in the case of default of any securities borrower. Collateral received and securities loaned are marked to market daily to ensure that the securities loaned are secured by collateral. The lending agent currently invests the cash collateral received in Government Money Market Portfolio, an eligible money market vehicle, in accordance with the investment restrictions of the Fund, and as approved by the Board. The collateral received on securities loaned is recorded as an asset as well as a corresponding liability in the statement of assets and liabilities. When the Fund lends securities, its investment performance will continue to reflect changes in the value of the securities loaned. At November 30, 2017, the Fund had securities on loan with a value of $4,840,941 and had

30    ^|    AB CORE OPPORTUNITIES FUND abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

received cash collateral which has been invested into Government Money Market Portfolio of $4,927,375. The cash collateral will be adjusted on the next business day to maintain the required collateral amount. The Fund earned securities lending income of $3,306 and $24,602 from the borrowers and Government Money Market Portfolio, respectively, for the year ended November 30, 2017; these amounts are reflected in the statement of operations. In connection with the cash collateral investment by the Fund in the Government Money Market Portfolio, the Adviser has agreed to waive a portion of the Fund’s share of the advisory fees of Government Money Market Portfolio, as borne indirectly by the Fund as an acquired fund fee and expense. For the year ended November 30, 2017, such waiver amounted to $4,787. A principal risk of lending portfolio securities is that the borrower may fail to return the loaned securities upon termination of the loan and that the collateral will not be sufficient to replace the loaned securities.

NOTE G

Risks Involved in Investing in the Fund

Focused Portfolio Risk—Investments in a limited number of companies may have more risk because changes in the value of a single security may have a more significant effect, either negative or positive, on the Fund’s net asset value, or NAV.

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 less liquid 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—The Fund may enter into derivative transactions such as forwards, options, futures and swaps. Derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses for the Fund, and subject to counterparty risk to a greater degree than more traditional investments. Derivatives may result in significant losses, including losses that are far greater than the value of the derivatives reflected on the statement of assets and liabilities.

abfunds.com AB CORE OPPORTUNITIES FUND    ^|    33

NOTES TO FINANCIAL STATEMENTS (continued)

Indemnification Risk—In the ordinary course of business, the Fund enters into contracts that contain a variety of indemnifications. The Fund’s maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these indemnification provisions and expects the risk of loss thereunder to be remote. Therefore, the Fund has not accrued any liability in connection with these indemnification provisions.

NOTE H

Joint Credit Facility

A number of open-end mutual funds managed by the Adviser, including the Fund, participate in a $280 million revolving credit facility (the “Facility”) intended to provide short-term financing, if necessary, subject to certain restrictions in connection with abnormal redemption activity. Commitment fees related to the Facility are paid by the participating funds and are included in miscellaneous expenses in the statement of operations. The Fund did not utilize the Facility during the year ended November 30, 2017.

NOTE I

Distributions to Shareholders

The tax character of distributions paid during the fiscal years ended November 30, 2017 and November 30, 2016 were as follows:

	2017		2016
Distributions paid from:
Ordinary income	$	696,118	$	465,591
Net long-term capital gains		9,488,441		10,470,673
Total taxable distributions paid	$	10,184,559	$	10,936,264

As of November 30, 2017, the components of accumulated earnings/(deficit) on a tax basis were as follows:

Undistributed ordinary income	$	8,087,387
Undistributed capital gains		19,222,761
Unrealized appreciation/(depreciation)		47,893,630	(a)
Total accumulated earnings/(deficit)	$	75,203,778

(a) The difference between book-basis and tax-basis unrealized appreciation/(depreciation) is attributable primarily to the tax deferral of losses on wash sales.

For tax purposes, net realized capital losses may be carried over to offset future capital gains, if any. Funds are permitted to carry forward capital losses for an indefinite period, and such losses will retain their character as either short-term or long-term capital losses. As of November 30, 2017, the Fund did not have any capital loss carryforwards.

During the current fiscal year, permanent differences primarily due to the redesignation of dividends, the offset to capital gains of a net operating loss, the utilization of earnings and profits distributed to shareholders on redemption of shares, and proceeds from a regulatory settlement resulted in a net decrease

34    ^|    AB CORE OPPORTUNITIES FUND abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

in distributions in excess of net investment income, a net decrease in accumulated net realized gain on investment transactions, and a net increase in additional paid-in capital. These reclassifications had no effect on net assets.

NOTE J

Subsequent Events

Management has evaluated subsequent events for possible recognition or disclosure in the financial statements through the date the financial statements are issued. Management has determined that there are no material events that would require disclosure in the Fund’s financial statements through this date.

REPORT OF INDEPENDENT REGISTERED

PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

AB Core Opportunities Fund, Inc.

We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of AB Core Opportunities Fund, Inc. (the “Fund”) as of November 30, 2017, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented therein. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of November 30, 2017, by correspondence with the custodian and others, or by other appropriate auditing procedures where replies from others were not received. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of AB Core Opportunities Fund, Inc. at November 30, 2017, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented therein, in conformity with U.S. generally accepted accounting principles.

Information Regarding the Review and Approval of the Fund’s Advisory Agreement

The disinterested directors (the “directors”) of AB Core Opportunities Fund, Inc. (the “Fund”) unanimously approved the continuance of the Advisory Agreement with the Adviser at a meeting held on May 2-4, 2017 (the “Meeting”).

Prior to approval of the continuance of the Advisory Agreement, the directors had requested from the Adviser, and received and evaluated, extensive materials. They reviewed the proposed continuance of the Advisory Agreement with the Adviser and with experienced counsel who are independent of the Adviser, who advised on the relevant legal standards. The directors also reviewed an independent evaluation prepared by the Fund’s Senior Officer (who is also the Fund’s Independent Compliance Officer), who acted as their independent fee consultant, of the reasonableness of the advisory fee, in which the Senior Officer concluded that the contractual fee for the Fund was reasonable. The directors also discussed the proposed continuance in private sessions with counsel and the Fund’s Senior Officer.

The directors considered their knowledge of the nature and quality of the services provided by the Adviser to the Fund gained from their experience as directors or trustees of most of the registered investment companies advised by the Adviser, their overall confidence in the Adviser’s integrity and competence they have gained from that experience, the Adviser’s initiative in identifying and raising potential issues with the directors and its responsiveness, frankness and attention to concerns raised by the directors in the past, including the Adviser’s willingness to consider and implement organizational and operational changes designed to improve investment results and the services provided to the AB Funds. The directors noted that they have four regular meetings each year, at each of which they review extensive materials and information from the Adviser, including information on the investment performance of the Fund.

The directors also considered all factors they believed relevant, including the specific matters discussed below. During the course of their deliberations, the directors evaluated, among other things, the reasonableness of the advisory fee. The directors did not identify any particular information that was all-important or controlling, and different directors may have attributed different weights to the various factors. The directors determined that the selection of the Adviser to manage the Fund and the overall arrangements between the Fund and the Adviser, as provided in the Advisory Agreement, including the advisory fee, were fair and reasonable in light of the services performed, expenses incurred and such other matters as the directors considered relevant in the exercise of their business judgment. The material factors and conclusions that formed the basis for the directors’ determinations included the following:

Nature, Extent and Quality of Services Provided

The directors considered the scope and quality of services provided by the Adviser under the Advisory Agreement, including the quality of the investment

56    ^|    AB CORE OPPORTUNITIES FUND abfunds.com

research capabilities of the Adviser and the other resources it has dedicated to performing services for the Fund. They also noted the professional experience and qualifications of the Fund’s portfolio management team and other senior personnel of the Adviser. The directors also considered that the Advisory Agreement provides that the Fund will reimburse the Adviser for the cost to it of providing certain clerical, accounting, administrative and other services to the Fund by employees of the Adviser or its affiliates. Requests for these reimbursements are made on a quarterly basis and subject to approval by the directors. Reimbursements, to the extent requested and paid, result in a higher rate of total compensation from the Fund to the Adviser than the fee rate stated in the Advisory Agreement. The directors noted that the methodology used to determine the reimbursement amounts had been reviewed by an independent consultant retained by the Fund’s Senior Officer. The quality of administrative and other services, including the Adviser’s role in coordinating the activities of the Fund’s other service providers, also was considered. The directors concluded that, overall, they were satisfied with the nature, extent and quality of services provided to the Fund under the Advisory Agreement.

Costs of Services Provided and Profitability

The directors reviewed a schedule of the revenues and expenses and related notes indicating the profitability of the Fund to the Adviser for calendar years 2015 and 2016 that had been prepared with an expense allocation methodology arrived at in consultation with an independent consultant retained by the Fund’s Senior Officer. The directors noted the assumptions and methods of allocation used by the Adviser in preparing fund-specific profitability data and understood that there are a number of potentially acceptable allocation methodologies for information of this type. The directors noted that the profitability information reflected all revenues and expenses of the Adviser’s relationship with the Fund, including those relating to its subsidiaries that provide transfer agency, distribution and brokerage services to the Fund. The directors recognized that it is difficult to make comparisons of the profitability of the Advisory Agreement with the profitability of advisory contracts for unaffiliated funds because comparative information is not generally publicly available and is affected by numerous factors. The directors focused on the profitability of the Adviser’s relationship with the Fund before taxes and distribution expenses. The directors concluded that the Adviser’s level of profitability from its relationship with the Fund was not unreasonable.

Fall-Out Benefits

The directors considered the other benefits to the Adviser and its affiliates from their relationships with the Fund, including, but not limited to, benefits relating to soft dollar arrangements (whereby investment advisers receive brokerage and research services from brokers that execute agency transactions for their clients); 12b-1 fees and sales charges received by the Fund’s principal underwriter (which is a wholly owned subsidiary of the

abfunds.com AB CORE OPPORTUNITIES FUND    ^|    57

Adviser) in respect of certain classes of the Fund’s shares; brokerage commissions paid by the Fund to brokers affiliated with the Adviser; and transfer agency fees paid by the Fund to a wholly owned subsidiary of the Adviser. The directors recognized that the Adviser’s profitability would be somewhat lower without these benefits. The directors understood that the Adviser also might derive reputational and other benefits from its association with the Fund.

Investment Results

In addition to the information reviewed by the directors in connection with the Meeting, the directors receive detailed performance information for the Fund at each regular Board meeting during the year.

At the Meeting, the directors reviewed information prepared by an analytical service that is not affiliated with the Adviser (the “15(c) service provider”), showing the performance of the Class A Shares of the Fund against a peer group and a peer universe, and information prepared by the Adviser showing performance of the Class A Shares against a broad-based securities market index, in each case for the 1-, 3-, 5- and 10-year periods ended February 28, 2017 and (in the case of comparisons with the broad-based securities market index) for the period from inception. Based on their review, the directors concluded that the Fund’s investment performance was acceptable.

Advisory Fees and Other Expenses

The directors considered the advisory fee rate paid by the Fund to the Adviser and information prepared by the 15(c) service provider concerning advisory fee rates paid by other funds in the same category as the Fund at a common asset level. The directors recognized that it is difficult to make comparisons of advisory fees because there are variations in the services that are included in the fees paid by other funds. The directors compared the Fund’s contractual effective advisory fee rate with a peer group median and took into account the impact on the advisory fee rate of the administrative expense reimbursement paid to the Adviser in the latest fiscal year.

The directors also considered the Adviser’s fee schedule for institutional clients pursuing a similar investment style. For this purpose, they reviewed the relevant advisory fee information from the Adviser’s Form ADV and the evaluation from the Fund’s Senior Officer and noted the differences between the Fund’s fee schedule, on the one hand, and the institutional fee schedule and the schedule of fees charged to any offshore funds and any sub-advised funds, on the other. The directors noted that the Adviser may, in some cases, agree to fee rates with large institutional clients that are lower than those reviewed by the directors and that they had previously discussed with the Adviser its policies in respect of such arrangements.

58    ^|    AB CORE OPPORTUNITIES FUND abfunds.com

The Adviser reviewed with the directors the significantly greater scope of the services it provides to the Fund relative to institutional, offshore fund and sub-advised fund clients. In light of the substantial differences in services rendered by the Adviser to institutional, offshore fund and sub-advised fund clients as compared to funds such as the Fund, the directors considered these fee comparisons inapt and did not place significant weight on them in their deliberations.

The directors also considered the total expense ratio of the Class A shares of the Fund in comparison to a peer group and a peer universe selected by the 15(c) service provider. The Class A expense ratio of the Fund was based on the Fund’s latest fiscal year and the directors considered the effects of any fee waivers and/or expense reimbursements as a result of the Adviser’s expense cap. The directors noted that it was likely that the expense ratios of some of the other funds in the Fund’s category were lowered by waivers or reimbursements by those funds’ investment advisers, which in some cases might be voluntary or temporary. The directors view expense ratio information as relevant to their evaluation of the Adviser’s services because the Adviser is responsible for coordinating services provided to the Fund by others. Based on their review, the directors concluded that the Fund’s expense ratio was acceptable.

Economies of Scale

The directors noted that the advisory fee schedule for the Fund contains breakpoints that reduce the fee rates on assets above specified levels. The directors took into consideration prior presentations by an independent consultant on economies of scale in the mutual fund industry and for the AB Funds, and by the Adviser concerning certain of its views on economies of scale. The directors also had requested and received from the Adviser certain updates on economies of scale in advance of the Meeting. The directors believe that economies of scale may be realized (if at all) by the Adviser across a variety of products and services, and not only in respect of a single fund. The directors noted that there is no established methodology for setting breakpoints that give effect to the fund-specific services provided by a fund’s adviser and to the economies of scale that an adviser may realize in its overall mutual fund business or those components of it which directly or indirectly affect a fund’s operations. The directors observed that in the mutual fund industry as a whole, as well as among funds similar to the Fund, there is no uniformity or pattern in the fees and asset levels at which breakpoints (if any) apply. The directors also noted that the advisory agreements for many funds do not have breakpoints at all. Having taken these factors into account, the directors concluded that the Fund’s shareholders would benefit from a sharing of economies of scale in the event the Fund’s net assets exceed a breakpoint in the future.
