NOTES TO FINANCIAL STATEMENTS

January 31, 2025 (unaudited)

NOTE A

Significant Accounting Policies

The AB Discovery Growth Fund, Inc. (the “Fund”) is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The Fund offers Class A, Class C, Advisor Class, Class I and Class Z shares. Class B, Class R, Class K and Class T shares have been authorized but currently are not offered. Effective May 20, 2024, Class R & Class K were liquidated. 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 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. Class C shares automatically convert to Class A shares eight years after the end of the calendar month of purchase. 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.

1. Security Valuation

Portfolio securities are valued at market value determined on the basis of market quotations or, if market quotations are not readily available or are unreliable, at “fair value” as determined in accordance with procedures approved by and under the oversight of the Fund’s Board of Directors (the “Board”). Pursuant to these procedures, AllianceBernstein L.P. (the “Adviser”) serves as the Fund’s valuation designee pursuant to Rule 2a-5 of the 1940 Act. In this capacity, the Adviser is responsible, among other things, for making all fair value determinations relating to the Fund’s portfolio investments, subject to the Board’s oversight.

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

ABFunds.com AB Discovery Growth Fund 9

NOTES TO FINANCIAL STATEMENTS (continued)

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, 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. 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 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)

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.

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

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.

12 AB Discovery Growth Fund ABFunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

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. Non-cash dividends, if any, are recorded on the ex-dividend date at the fair value of the securities received. The Fund amortizes premiums and accretes discounts as adjustments to interest income. The Fund accounts for distributions received from real estate investment trust (“REIT”) investments or from regulated investment companies as dividend income, realized gain, or return of capital based on information provided by the REIT or the investment company.

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.

8. Cash and Short-Term Investments

Cash and short-term investments include cash on hand and short-term investments with maturities of less than one year when purchased.

9. Segment Information

The Fund represents a single operating segment. An operating segment is defined in U.S. GAAP as a component of a public entity that engages in

ABFunds.com AB Discovery Growth Fund 13

NOTES TO FINANCIAL STATEMENTS (continued)

business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by the public entity’s chief operating decision maker (“CODM”) to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available. The Fund’s President is the CODM. The CODM monitors the operating results of the Fund as a whole and the pre-determined Fund’s long term investoment strategy, which is executed by the portfolio management group. The qualitative and quantitative information contained within the financial statements is used by the CODM to assess the segments performance versus the Fund’s comparative benchmark and to make resource allocation decisions. Segment assets are reflected on the statement of assets and liabilities and segment expenses are listed on the statement of operations.

NOTE B

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 .75% on the first $500 million of average daily net assets, .65% on the next $500 million of average daily net assets and .55% on average daily net assets in excess of $1 billion. Such fee is accrued daily and paid monthly.

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 six months ended January 31, 2025, the reimbursement for such services amounted to $40,648.

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 $336,768 for the six months ended January 31, 2025.

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 $2,309 from the sale of Class A shares and received $2,806 and $-0- in contingent deferred sales charges imposed upon redemptions by shareholders of Class A and Class C shares, respectively, for the six months ended January 31, 2025.

The Fund may invest in AB Government Money Market Portfolio which has a contractual annual advisory fee rate of .20% of the portfolio’s average daily net assets and bears its own expenses. The Adviser had contractually agreed to waive .10% of the advisory fee of AB Government Money Market Portfolio

NOTES TO FINANCIAL STATEMENTS (continued)

(resulting in a net advisory fee of .10%) until August 31, 2023. Effective September 1, 2023, the Adviser has contractually agreed to waive .05% of the advisory fee of AB Government Money Market Portfolio (resulting in a net advisory fee of .15%) until August 31, 2024. In connection with the investment by the Fund in AB Government Money Market Portfolio, the Adviser has contractually agreed to waive its advisory fee from the Fund in an amount equal to the Fund’s pro rata share of the effective advisory fee of AB Government Money Market Portfolio, as borne indirectly by the Fund as an acquired fund fee and expense. For the six months ended January 31, 2025, such waiver amounted to $42,764.

NOTE C

Distribution Services Agreement

The Fund has adopted a Distribution Services Agreement (the “Agreement”) pursuant to Rule 12b-1 under the 1940 Act. 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 Class C shares. There are no distribution and servicing fees on the Advisor Class, Class I and Class Z shares. The fees are accrued daily and paid monthly. Payments under the Agreement in respect of Class A shares are currently limited to an annual rate of .23% of Class A shares’ average daily net assets. 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 $3,111,526, for Class C shares. While such costs may be recovered from the Fund in future periods so long as the Agreement is in effect, and the share class is active, 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

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 six months ended January 31, 2025.

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 forward currency exchange contracts, 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 collateral and/or non-cash collateral. Non-cash collateral will include only securities issued or guaranteed by the U.S. government or its agencies or instrumentalities. If the Fund cannot sell or repledge any non-cash collateral, such collateral will not be reflected in the portfolio of investments. If a loan is collateralized 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. If the Fund receives non-cash collateral, the Fund will receive a fee from the borrower generally equal to a negotiated percentage of the market value of the loaned securities. 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 dividend income or other distributions from the securities; however, these distributions will not be afforded the same preferential tax treatment as qualified dividends. 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. 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 AB 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. The collateral will be adjusted the next business day to maintain the required collateral amount. The amounts of securities lending income from the borrowers and AB Government Money Market Portfolio are reflected in the statement of operations. When the Fund earns net securities lending income from AB Government Money Market Portfolio, the income is inclusive of a rebate expense paid to the borrower. In connection with the cash collateral investment by the Fund in AB Government Money Market Portfolio, the Adviser has agreed to waive a portion of the Fund’s share of the advisory fees of AB Government Money Market Portfolio, as borne indirectly by the Fund as an acquired fund fee and expense. When the Fund lends securities, its investment performance will continue to reflect changes in the value of the securities loaned. 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. The lending agent has agreed to indemnify the Fund in the case of default of any securities borrower.

Risks Involved in Investing in the Fund

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 industrials or 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.

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

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.

ABFunds.com AB Discovery Growth Fund 19

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.

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.

NOTE H

Joint Credit Facility

A number of open-end mutual funds managed by the Adviser, including the Fund, participate in a $325 million revolving credit facility (the “Facility”) intended to provide short-term financing related to redemptions and other short-term liquidity requirements, subject to certain restrictions. 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 six months ended January 31, 2025.

NOTE I

Distributions to Shareholders

The tax character of distributions to be paid for the year ending July 31, 2025 will be determined at the end of the current fiscal year. The tax character of distributions paid during the fiscal years ended July 31, 2024 and July 31, 2023 were as follows:

Other losses		(3,280,049	)(b)
Unrealized appreciation (depreciation)		372,145,103	(c)
Total accumulated earnings (deficit)	$	323,812,130

(a) As of July 31, 2024, the Fund had a net capital loss carryforward of $45,052,924. During the fiscal year, the Fund utilized $151,369,992 of capital loss carry forwards to offset current year net realized gains.

(b) As of July 31, 2024, the Fund had a qualified late-year ordinary loss deferral of $3,280,049.

(c) The differences between book-basis and tax-basis unrealized appreciation (depreciation) are attributable primarily to the tax treatment of passive foreign investment companies (PFICs) and 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 July 31, 2024, the Fund had a net short-term capital loss carryforward of $45,052,924 which may be carried forward for an indefinite period.

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

The disinterested directors (the “directors”) of AB Discovery Growth Fund, Inc. (the “Fund”) unanimously approved the continuance of the Fund’s Advisory Agreement with the Adviser at a meeting held by video conference on May 7-9, 2024 (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 additional materials, including comparative analytical data prepared by the Senior Vice President of the Fund. The directors also discussed the proposed continuance in private sessions with counsel.

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 and the money market fund advised by the Adviser in which the Fund invests a portion of its assets.

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 research capabilities of the Adviser and the other resources it has dedicated to

28 AB Discovery Growth Fund ABFunds.com

performing services for the Fund. The directors noted that the Adviser from time to time reviews the Fund’s investment strategies and from time to time proposes changes intended to improve the Fund’s relative or absolute performance for the directors’ consideration. 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 at the request of the directors. 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 2022 and 2023 that had been prepared with an expense allocation methodology arrived at in consultation with an independent consultant at the request of the directors. 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 fund 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 and the money market fund advised by the Adviser in which the Fund invests, 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

ABFunds.com AB Discovery Growth Fund 29

clients); 12b-1 fees and sales charges received by the Fund’s principal underwriter (which is a wholly owned subsidiary of the 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 performance information prepared by an independent service provider (the “15(c) service provider”), showing the performance of the Advisor Class shares of the Fund against a group of similar funds (“peer group”) and a larger group of similar funds (“peer universe”), each selected by the 15(c) service provider, and information prepared by the Adviser showing performance of the Advisor Class shares against a broad-based securities market index, in each case for the 1-, 3-, 5- and 10-year periods ended February 29, 2024 (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 payable by the Fund to the Adviser and information prepared by the 15(c) service provider concerning advisory fee rates payable by other funds in the same category as the Fund. 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 noted that it was lower than the median. They also noted that the Adviser’s total rate of compensation, taking into account the impact of the administrative expense reimbursement paid to the Adviser in the latest fiscal year, was lower than the median.

The directors also considered the Adviser’s fee schedule for other clients utilizing investment strategies similar to those of the Fund. For this purpose, they reviewed the relevant advisory fee information from the Adviser’s Form ADV and in a report from the Fund’s Senior Vice President and noted the differences between the Fund’s fee schedule, on the one hand, and the Adviser’s institutional fee schedule and the schedule of fees charged by the Adviser to any offshore funds and for services to any sub-advised funds utilizing investment strategies similar to those of the Fund, 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.

30 AB Discovery Growth 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 this regard, the Adviser noted, among other things, that, compared to institutional and offshore or sub-advisory accounts, the Fund (i) demands considerably more portfolio management, research and trading resources due to significantly higher daily cash flows; (ii) has more tax and regulatory restrictions and compliance obligations; (iii) must prepare and file or distribute regulatory and other communications about fund operations; and (iv) must provide shareholder servicing to retail investors. The Adviser also reviewed the greater legal risks presented by the large and changing population of Fund shareholders who may assert claims against the Adviser in individual or class actions, and the greater entrepreneurial risk in offering new fund products, which require substantial investment to launch, may not succeed, and generally must be priced to compete with larger, more established funds resulting in lack of profitability to the Adviser until a new fund achieves scale. In light of the substantial differences in services rendered by the Adviser to institutional, offshore fund and sub-advised fund clients as compared to the Fund, and the different risk profile, the directors considered these fee comparisons inapt and did not place significant weight on them in their deliberations.

In connection with their review of the Fund’s advisory fee, the directors also considered the total expense ratio of the Advisor Class shares of the Fund in comparison to the medians for a peer group and a peer universe selected by the 15(c) service provider. The Advisor Class expense ratio of the Fund was based on the Fund’s latest fiscal year. 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. The directors noted that the Fund’s expense ratio was lower than the medians. 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 and that the Fund’s net assets were higher than the breakpoint levels. Accordingly, the Fund’s current effective advisory fee rate reflected a reduction due to the breakpoints and would be further reduced to the extent the net assets of the Fund increase. 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 presentations from time to time 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

ABFunds.com AB Discovery Growth Fund 31

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 breakpoint arrangements were acceptable and provide a means for sharing of any economies of scale.
