December 19, 2023

This report provides management’s discussion of fund performance for AB Corporate Income Shares for the semi-annual reporting period ended October 31, 2023. Please note, shares of this Fund are available only to separately managed accounts or participants in “wrap fee” programs or other investment programs approved by the Adviser.

NAV RETURNS AS OF OCTOBER 31, 2023 (unaudited)

	6 Months		12 Months
AB CORPORATE INCOME SHARES		-5.50%		3.39%
Bloomberg US Credit Bond Index		-5.77%		2.69%

INVESTMENT RESULTS

The table above shows the Fund’s performance compared with its benchmark, the Bloomberg US Credit Bond Index, for the six- and 12-month periods ended October 31, 2023.

During both periods, the Fund outperformed the benchmark. Over the six-month period, security selection was the largest contributor, relative to the benchmark, primarily from gains in banking, energy, electric, technology and consumer noncyclical. Industry allocation also contributed, as lack of exposure to supranationals and overweights to media, energy and technology exceeded a loss from exposure to investment-grade credit default swaps. Yield-curve positioning detracted, mostly due to losses from overweights to the three- to five-year and six- to 10-year parts of the curve. An underweight to maturities 10 years and longer detracted more than gains from an underweight to the less-than-one-year to two-year parts of the curve.

Over the 12-month period, security selection contributed the most. Gains from selection in banking, technology, energy and electric added more to performance than losses from selection in real estate investment trusts, basic industry and capital goods. Industry allocation also contributed as a result of gains from lack of exposure to supranationals, provincial bonds and agency government guaranteed bonds. Overweights to basic industry, media, energy and technology contributed more than losses from lack of exposure to sovereign government guaranteed bonds. Yield-curve positioning detracted from performance, primarily from overweights to the three- to four-year and six- to seven-year parts of the curve and an underweight to the seven- to 10-year parts of the curve that were partially offset by gains from overweights to the less-than-one-year and four- to five-year parts of the curve.

During both periods, the Fund used derivatives in the form of futures and credit default swaps for hedging purposes; futures detracted from absolute returns for both periods, while credit default swaps detracted for the six-month period and had no material impact on returns for the 12-month period. During the 12-month period, interest rate swaps were utilized for hedging purposes and added.

MARKET REVIEW AND INVESTMENT STRATEGY

During the six-month period ended October 2023, fixed-income government bond market yields were volatile as investors adjusted their expectations for inflation and economic growth. US Treasury yields led global developed-market yields higher over the period, supported by strong US economic growth in the third calendar quarter, and as the Fed convinced investors that interest rates would stay higher for longer to slow growth. Most developed-market central banks appeared to reach peak interest rates as inflation continued to cool. Government bond returns were negative across all major developed countries, with the largest losses in the US, UK and Canada, while government bonds fell the least in the eurozone as economic growth slowed considerably. Although developed-market investment-grade corporate bonds trailed government bonds, investment-grade corporates in the US outperformed US Treasuries with a smaller loss, while eurozone investment-grade corporates had positive returns and outperformed the negative return of eurozone treasuries. High-yield corporate bonds had positive returns overall and outperformed treasuries in the US and eurozone by a wide margin. Hard-currency emerging-market sovereign bonds outperformed developed-market treasuries. Emerging-market investment-grade and high-yield corporates outperformed respective developed-market returns. Emerging-market local-currency debt trailed other risk sectors as the US dollar gained on almost all currencies.

The Fund’s Senior Investment Management Team (the “Team”) continues to seek attractively priced securities through top-down and bottom-up research, while mitigating overall risk. The Team invests primarily in single-sector, investment-grade issues of global corporates.

INVESTMENT POLICIES

The Fund invests, under normal circumstances, at least 80% of its net assets in US corporate bonds. The Fund may also invest in US government securities (other than US government securities that are mortgage-backed or asset-backed securities), repurchase agreements and forward contracts relating to US government securities. The Fund normally invests all of its assets in securities that are rated, at the time of purchase, at least BBB-or the equivalent by any nationally recognized statistical rating organization. The Fund will not invest

(continued on next page)

in unrated corporate debt securities. The Fund has the flexibility to invest in long-and short-term fixed-income securities. In making decisions about whether to buy or sell securities, the Adviser will consider, among other things, the strength of certain sectors of the fixed-income market relative to others, interest rates and other general market conditions and the credit quality of individual issuers.

The Fund also may: invest in convertible debt securities; invest up to 10% of its assets in inflation-indexed securities; invest up to 5% of its net assets in preferred stock; purchase and sell interest rate futures contracts and options; enter into swap transactions; invest in zero-coupon securities and “payment-in-kind” debentures; make secured loans of portfolio securities; and invest in US dollar-denominated fixed-income securities issued by non-US companies.

DISCLOSURES AND RISKS

Benchmark Disclosure

The Bloomberg US Credit Bond Index is unmanaged and does not reflect fees and expenses associated with the active management of a fund. The Bloomberg US Credit Bond Index represents the performance of the US credit securities within the US fixed-income market. An investor cannot invest directly in an index, and its 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 assets will fluctuate as the stock or bond market fluctuates. 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.

Credit Risk: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security and any accrued interest. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.

Interest-Rate Risk: Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of existing investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest-rate risk is generally greater for fixed-income securities with longer maturities or durations. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the end of a recent period of historically low rates and the effect of potential central bank monetary policy, and government fiscal policy, initiatives and resulting market reactions to those initiatives.

Duration Risk: Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise.

Inflation Risk: This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of

DISCLOSURES AND RISKS (continued)

money. As inflation increases, the value of the Fund’s assets can decline as can the value of the Fund’s distributions. This risk is significantly greater for fixed-income securities with longer maturities.

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 more difficult to trade due to adverse market, economic, political, regulatory or other factors.

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

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

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

EXPENSE EXAMPLE

(unaudited)

As a shareholder of the Fund, you may incur various ongoing non-operating and extraordinary costs. 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 in this line, 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 in the first line 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 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.

	Beginning Account Value May 1, 2023		Ending Account Value October 31, 2023		Expenses Paid During Period*			Annualized Expense Ratio*
Actual	$	1,000	$	945.00	$	– 0	–		0.00	%
Hypothetical**	$	1,000	$	1,025.14	$	– 0	–		0.00	%

* Expenses are equal to the Fund’s annualized expense ratio, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). The Fund’s operating expenses are borne by the Adviser or its affiliates.

** Assumes 5% annual return before expenses.

NOTE A

Significant Accounting Policies

AB Corporate Shares (the “Trust”) is registered under the Investment Company Act of 1940 (the “1940 Act”), as an open-end, diversified management investment company. The Trust, which is a Massachusetts Business Trust, operates as a “series” company currently offering five separate portfolios: AB Corporate Income Shares, AB Municipal Income Shares, AB Taxable Multi-Sector Income Shares, AB Impact Municipal Income Shares and AB Tax-Aware Real Return Income Shares. Each portfolio is considered to be a separate entity for financial reporting and tax purposes. This report relates only to AB Corporate Income Shares (the “Fund”).

Shares of the Fund are offered exclusively to holders of accounts established under wrap-fee programs sponsored and maintained by certain registered investment advisers approved by AllianceBernstein L.P. (the “Adviser”). The Fund’s shares may be purchased at the relevant net asset value without a sales charge or other fee. 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.

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 Trust’s Board of Trustees (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 sale on such day, the securities are valued at the last traded price from the previous day. Securities listed on more

NOTES TO FINANCIAL STATEMENTS (continued)

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

32    ^|    AB CORPORATE INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

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)

The fair value of debt instruments, such as bonds, and over-the-counter derivatives is generally based on market price quotations, recently executed market transactions (where observable) or industry recognized modeling techniques and are generally classified as Level 2. Pricing vendor inputs to Level 2 valuations may include quoted prices for similar investments in active markets, interest rate curves, coupon rates, currency rates, yield curves, option adjusted spreads, default rates, credit spreads and other unique security features in order to estimate the relevant cash flows which are then discounted to calculate fair values. If these inputs are unobservable and significant to the fair value, these investments will be classified as Level 3.

Other fixed income investments, including non-U.S. government and corporate debt, are generally valued using quoted market prices, if available, which are typically impacted by current interest rates, maturity dates and

abfunds.com AB CORPORATE INCOME SHARES    ^|    33

NOTES TO FINANCIAL STATEMENTS (continued)

any perceived credit risk of the issuer. Additionally, in the absence of quoted market prices, these inputs are used by pricing vendors to derive a valuation based upon industry or proprietary models which incorporate issuer specific data with relevant yield/spread comparisons with more widely quoted bonds with similar key characteristics. Those investments for which there are observable inputs are classified as Level 2. Where the inputs are not observable, the investments are classified as Level 3.

The following table summarizes the valuation of the Fund’s investments by the above fair value hierarchy levels as of October 31, 2023:

(a) Other financial instruments include reverse repurchase agreements and 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.

(b) Only variation margin receivable (payable) at period end is reported within the statement of assets and liabilities. This amount reflects cumulative unrealized appreciation (depreciation) on futures and centrally cleared swaps as reported in the portfolio of investments. Where applicable, centrally cleared swaps with upfront premiums are presented here at market value.

3. 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.

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.

4. 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 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.

5. 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.

NOTE B

Advisory Fee and Other Transactions with Affiliates

Under the terms of the Advisory Agreement, the Fund pays no advisory fee to the Adviser and the Adviser reimburses or pays for the Fund’s operating expenses. The Fund is an integral part of separately managed accounts in wrap-fee programs and other investment programs. Typically, participants in these programs pay a fee to their investment adviser for all costs and expenses of the separately managed account, including costs and expenses associated with the Fund, and a fee is paid by their investment adviser to the Adviser. In certain cases, participants may have a direct relationship with the Adviser without the involvement of a third party investment adviser, in which case the participant would pay a fee directly to the Adviser. The Adviser serves as investment manager and adviser of the Fund and continuously furnishes an investment program for the Fund and manages, supervises and conducts the affairs of the Fund, subject to the supervisions of the Fund’s Board. The Advisory Agreement provides that the Adviser or an affiliate will furnish, or pay the expenses of the Fund for, office space, facilities and equipment, services of executive and other personnel of the Fund and certain administrative services.

The Fund has entered into a distribution agreement with AllianceBernstein Investments, Inc., the Fund’s principal underwriter (the “Underwriter”), to permit the Underwriter to distribute the Fund’s shares, which are sold at their

abfunds.com AB CORPORATE INCOME SHARES    ^|    35

NOTES TO FINANCIAL STATEMENTS (continued)

net asset value without any sales charge. The Fund does not pay a fee for this service. The Underwriter is a wholly owned subsidiary of the Adviser.

AllianceBernstein Investor Services, Inc. (“ABIS”), a wholly-owned subsidiary of the Adviser, acts as the Fund’s registrar, transfer agent and dividend-disbursing agent. ABIS registers the transfer, issuance and redemption of Fund shares and disburses dividends and other distributions to Fund shareholders. The Fund does not pay a fee for this service.

NOTE C

Investment Transactions

Purchases and sales of investment securities (excluding short-term investments) for the six months ended October 31, 2023 were as follows:

	Purchases			Sales
Investment securities (excluding U.S. government securities)	$	155,323,959		$	118,519,431
U.S. government securities		– 0	–		– 0	–

The cost of investments for federal income tax purposes was substantially the same as the cost for financial reporting purposes. Accordingly, gross unrealized appreciation and unrealized depreciation are as follows:

Gross unrealized appreciation	$	451,014
Gross unrealized depreciation		(18,485,645	)
Net unrealized depreciation	$	(18,034,631	)

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 principal types of derivatives utilized by the Fund, as well as the methods in which they may be used are:

• Futures

The Fund may buy or sell futures for investment purposes or for the purpose of hedging its portfolio against adverse effects of potential movements in the market. The Fund bears the market risk that arises from changes in the value of these instruments and the imperfect correlation between movements in the price of the futures and movements in the price of the assets, reference rates or indices which they are designed to track. Among other things, the Fund may purchase or sell futures for foreign currencies or options thereon for non-hedging purposes as a means of making direct investment in foreign currencies.

36    ^|    AB CORPORATE INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

At the time the Fund enters into futures, the Fund deposits and maintains as collateral an initial margin with the broker, as required by the exchange on which the transaction is effected. Such amount is shown as cash collateral due from broker on the statement of assets and liabilities. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. Risks may arise from the potential inability of a counterparty to meet the terms of the contract. The credit/counterparty risk for exchange-traded futures is generally less than privately negotiated futures, since the clearinghouse, which is the issuer or counterparty to each exchange-traded future, has robust risk mitigation standards, including the requirement to provide initial and variation margin. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the time it was closed.

Use of long futures subjects the Fund to risk of loss in excess of the amounts shown on the statement of assets and liabilities, up to the notional value of the futures. Use of short futures subjects the Fund to unlimited risk of loss. Under some circumstances, futures exchanges may establish daily limits on the amount that the price of futures can vary from the previous day’s settlement price, which could effectively prevent liquidation of unfavorable positions.

During the six months ended October 31, 2023, the Fund held futures for hedging purposes.

• Swaps

The Fund may enter into swaps to hedge its exposure to interest rates or credit risk. A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. The payment flows are usually netted against each other, with the difference being paid by one party to the other. In addition, collateral may be pledged or received by the Fund in accordance with the terms of the respective swaps to provide value and recourse to the Fund or its counterparties in the event of default, bankruptcy or insolvency by one of the parties to the swap.

Risks may arise as a result of the failure of the counterparty to the swap to comply with the terms of the swap. The loss incurred by the failure of a counterparty is generally limited to the net interim payment to be received by the Fund, and/or the termination value at the end of the contract. Therefore, the Fund considers the creditworthiness of

abfunds.com AB CORPORATE INCOME SHARES    ^|    37

NOTES TO FINANCIAL STATEMENTS (continued)

each counterparty to a swap in evaluating potential counterparty risk. This risk is mitigated by having a netting arrangement between the Fund and the counterparty and by the posting of collateral by the counterparty to the Fund to cover the Fund’s exposure to the counterparty. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying securities. The Fund accrues for the interim payments on swaps on a daily basis, with the net amount recorded within unrealized appreciation/depreciation of swaps on the statement of assets and liabilities, where applicable. Once the interim payments are settled in cash, the net amount is recorded as realized gain/(loss) on swaps on the statement of operations, in addition to any realized gain/(loss) recorded upon the termination of swaps. Upfront premiums paid or received for swaps are recognized as cost or proceeds on the statement of assets and liabilities and are amortized on a straight line basis over the life of the contract. Amortized upfront premiums are included in net realized gain/(loss) from swaps on the statement of operations. Fluctuations in the value of swaps are recorded as a component of net change in unrealized appreciation/depreciation of swaps on the statement of operations.

Certain standardized swaps, including certain interest rate swaps and credit default swaps, are (or soon will be) subject to mandatory central clearing. Cleared swaps are transacted through futures commission merchants (“FCMs”) that are members of central clearinghouses, with the clearinghouse serving as central counterparty, similar to transactions in futures contracts. Centralized clearing will be required for additional categories of swaps on a phased-in basis based on requirements published by the Securities and Exchange Commission and Commodity Futures Trading Commission.

At the time the Fund enters into a centrally cleared swap, the Fund deposits and maintains as collateral an initial margin with the broker, as required by the clearinghouse on which the transaction is effected. Such amount is shown as cash collateral due from broker on the statement of assets and liabilities. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. Risks may arise from the potential inability of a counterparty to meet the terms of the contract. The credit/counterparty risk for centrally cleared swaps is generally less than non-centrally cleared swaps, since the clearinghouse, which is the issuer or counterparty to each centrally cleared swap, has robust risk mitigation standards, including the requirement to provide initial and variation margin. When the contract is closed, the Fund records a

38    ^|    AB CORPORATE INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

realized gain or loss equal to the difference between the value of the contract at the time it was opened and the time it was closed.

Credit Default Swaps:

The Fund may enter into credit default swaps, including to manage its exposure to the market or certain sectors of the market, to reduce its risk exposure to defaults by corporate and sovereign issuers held by the Fund, or to create exposure to corporate or sovereign issuers to which it is not otherwise exposed. The Fund may purchase credit protection (“Buy Contract”) or provide credit protection (“Sale Contract”) on the referenced obligation of the credit default swap. During the term of the swap, the Fund receives/(pays) fixed payments from/(to) the respective counterparty, calculated at the agreed upon rate applied to the notional amount. If the Fund is a buyer/(seller) of protection and a credit event occurs, as defined under the terms of the swap, the Fund will either (i) receive from the seller/(pay to the buyer) of protection an amount equal to the notional amount of the swap (the “Maximum Payout Amount”) and deliver/(take delivery of) the referenced obligation or (ii) receive/(pay) a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation. In certain circumstances Maximum Payout Amounts may be partially offset by recovery values of the respective referenced obligations, upfront premium received upon entering into the agreement, or net amounts received from settlement of buy protection credit default swaps entered into by the Fund for the same referenced obligations with the same counterparty.

Credit default swaps may involve greater risks than if the Fund had invested in the referenced obligation directly. Credit default swaps are subject to general market risk, liquidity risk, counterparty risk and credit risk. If the Fund is a buyer of protection and no credit event occurs, it will lose the payments it made to its counterparty. If the Fund is a seller of protection and a credit event occurs, the value of the referenced obligation received by the Fund coupled with the periodic payments previously received, may be less than the Maximum Payout Amount it pays to the buyer, resulting in a net loss to the Fund.

Implied credit spreads over U.S. Treasuries of comparable maturity utilized in determining the market value of credit default swaps on issuers as of period end are disclosed in the portfolio of investments. The implied spreads serve as an indicator of the current status of the payment/performance risk and typically reflect the likelihood of default by the issuer of the referenced obligation. The implied credit spread of a particular reference obligation also reflects the cost of buying/selling protection and may reflect upfront payments required to be made to enter into the agreement. Widening credit spreads typically represent a

abfunds.com AB CORPORATE INCOME SHARES    ^|    39

NOTES TO FINANCIAL STATEMENTS (continued)

deterioration of the referenced obligation’s credit soundness and greater likelihood of default or other credit event occurring as defined under the terms of the agreement. A credit spread identified as “Defaulted” indicates a credit event has occurred for the referenced obligation.

During the six months ended October 31, 2023, the Fund held credit default swaps for non-hedging purposes.

The Fund typically enters into International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreement”) with its OTC derivative contract counterparties in order to, among other things, reduce its credit risk to OTC counterparties. ISDA Master Agreements include provisions for general obligations, representations, collateral and events of default or termination. Under an ISDA Master Agreement, the Fund typically may offset with the OTC counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment (close-out netting) in the event of default or termination. In the event of a default by an OTC counterparty, the return of collateral with market value in excess of the Fund’s net liability, held by the defaulting party, may be delayed or denied.

The Fund’s ISDA Master Agreements may contain provisions for early termination of OTC derivative transactions in the event the net assets of the Fund decline below specific levels (“net asset contingent features”). If these levels are triggered, the Fund’s OTC counterparty has the right to terminate such transaction and require the Fund to pay or receive a settlement amount in connection with the terminated transaction. If OTC derivatives were held at period end, please refer to netting arrangements by the OTC counterparty table below for additional details.

During the six months ended October 31, 2023, the Fund had entered into the following derivatives:

	Asset Derivatives				Liability Derivatives
Derivative Type	Statement of Assets and Liabilities Location	Fair Value			Statement of Assets and Liabilities Location	Fair Value
Interest rate contracts	Receivable for variation margin on futures	$	355,361	*	Payable for variation margin on futures	$	3,029,333	*
Credit contracts					Payable for variation margin on centrally cleared swaps		9,837	*
Total		$	355,361			$	3,039,170

* Only variation margin receivable/payable at period end is reported within the statement of assets and liabilities. This amount reflects cumulative unrealized appreciation (depreciation) on futures and centrally cleared swaps as reported in the portfolio of investments.

Risks Involved in Investing in the Fund

Market Risk—The value of the Fund’s assets will fluctuate as the stock or bond market fluctuates. 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.

abfunds.com AB CORPORATE INCOME SHARES    ^|    41

NOTES TO FINANCIAL STATEMENTS (continued)

Credit Risk—An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security and any accrued interest. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.

Interest-Rate Risk—Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of existing investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest-rate risk is generally greater for fixed-income securities with longer maturities or durations. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the recent end of a period of historically low rates and the effects of potential central bank monetary policy, and government fiscal policy, initiatives and market reactions to those initiatives.

Duration Risk—Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to the full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise.

Inflation Risk—This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Fund’s assets can decline as can the value of the Fund’s distributions. This risk is significantly greater for fixed-income securities with longer maturities.

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.

Derivatives Risk—Derivatives may be difficult to price or unwind and leveraged so that small changes may produce disproportionate losses for the Fund. A short position in a derivative instrument involves the risk of a theoretically unlimited increase in the value of the underlying asset, which could cause the Fund to suffer a potentially unlimited loss. Derivatives,

42    ^|    AB CORPORATE INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

especially over-the-counter derivatives, are also subject to counterparty risk, which is the risk that the counterparty (the party on the other side of the transaction) on a derivative transaction will be unable or unwilling to honor its contractual obligations to the Fund.

LIBOR Replacement Risk—The Fund may be exposed to debt securities, derivatives or other financial instruments that recently transitioned from the London Interbank Offered Rate, or “LIBOR,” as a “benchmark” or “reference rate” for various interest rate calculations. LIBOR’s administrator, ICE Benchmark Administration, ceased publishing most LIBOR settings (including some U.S. LIBOR settings) by the end of 2021 and the remaining (and most widely used) U.S. Dollar LIBOR settings after June 30, 2023. The United Kingdom Financial Conduct Authority, which regulates LIBOR, will permit the use of synthetic U.S. Dollar LIBOR rates for non-U.S. contracts through September 30, 2024, but any such rates would be considered non-representative of the underlying market. Since 2018 the Federal Reserve Bank of New York has published the Secured Overnight Financing Rate (referred to as SOFR), which is intended to replace U.S. Dollar LIBOR. SOFR is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities in the repurchase agreement (repo) market. There is no assurance that the composition or characteristics of SOFR or any such alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that the market for SOFR-linked financial instruments will have the same volume or liquidity as did the market for LIBOR-linked financial instruments prior to LIBOR’s discontinuance or unavailability. Neither the long-term effects of the LIBOR transition process nor its ultimate success can yet be known.

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, 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.

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 October 31, 2023.

Net long-term capital gains		– 0	–		2,240,925
Total distributions paid	$	6,423,355		$	9,462,001

As of April 30, 2023, the components of accumulated earnings (deficit) on a tax basis were as follows:

Undistributed ordinary income	$	694,916
Accumulated capital and other losses		(25,934,898	)(a)
Unrealized appreciation (depreciation)		(13,221,069	)(b)
Total accumulated earnings (deficit)	$	(38,461,051	)(c)

(a) As of April 30, 2023, the Fund had a net capital loss carryforward of $25,934,898.

(b) The differences between book-basis and tax-basis unrealized appreciation (depreciation) are attributable primarily to the recognition for tax purposes of unrealized gains/losses on certain derivative instruments, the tax treatment of callable bonds, the tax treatment of swaps, and the tax deferral of losses on wash sales.

(c) The difference between book-basis and tax-basis components of accumulated earnings (deficit) is attributable primarily to dividends payable.

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 April 30, 2023, the Fund had a net short-term capital loss carryforward of $11,821,465 and a net long-term capital loss carryforward of $14,113,433, which may be carried forward for an indefinite period.

Operation and Effectiveness of the Fund’s Liquidity Risk Management Program:

In October 2016, the Securities and Exchange Commission (“SEC”) adopted the open-end fund liquidity rule (the “Liquidity Rule”). In June 2018 the SEC adopted a requirement that funds disclose information about the operation and effectiveness of their Liquidity Risk Management Program (“LRMP”) in their reports to shareholders.

One of the requirements of the Liquidity Rule is for the Fund to designate an Administrator of the Fund’s Liquidity Risk Management Program. The Administrator of the Fund’s LRMP is AllianceBernstein L.P., the Fund’s investment adviser (the “Adviser”). The Adviser has delegated the responsibility to its Liquidity Risk Management Committee (the “Committee”).

Another requirement of the Liquidity Rule is for the Fund’s Board of Trustees (the “Fund Board”) to receive an annual written report from the Administrator of the LRMP, which addresses the operation of the Fund’s LRMP and assesses its adequacy and effectiveness. The Adviser provided the Fund Board with such annual report during the first quarter of 2023, which covered the period January 1, 2022 through December 31, 2022 (the “Program Reporting Period”).

The LRMP’s principal objectives include supporting the Fund’s compliance with limits on investments in illiquid assets and mitigating the risk that the Fund will be unable to meet its redemption obligations in a timely manner.

Pursuant to the LRMP, the Fund classifies the liquidity of its portfolio investments into one of the four categories defined by the SEC: Highly Liquid, Moderately Liquid, Less Liquid, and Illiquid. These classifications are reported to the SEC on Form N-PORT.

During the Program Reporting Period, the Committee reviewed whether the Fund’s strategy is appropriate for an open-end structure, incorporating any holdings of less liquid and illiquid assets. If the Fund participated in derivative transactions, the exposure from such transactions were considered in the LRMP.

The Committee also performed an analysis to determine whether the Fund is required to maintain a Highly Liquid Investment Minimum (“HLIM”). The Committee also incorporated the following information when determining the Fund’s reasonably anticipated trading size for purposes of liquidity monitoring: historical net redemption activity, a Fund’s concentration in an issuer, shareholder concentration, investment performance, total net assets, and distribution channels.

The Adviser informed the Fund Board that the Committee believes the Fund’s LRMP is adequately designed, has been implemented as intended,

48    ^|    AB CORPORATE INCOME SHARES abfunds.com

and has operated effectively since its inception. No material exceptions have been noted since the implementation of the LRMP. During the Program Reporting Period, liquidity in all markets was challenged due to rising rates and economic uncertainty. However, markets also remained orderly during the Program Reporting Period. There were no liquidity events that impacted the Fund or its ability to timely meet redemptions during the Program Reporting Period.

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

The disinterested trustees (the “directors”) of AB Corporate Shares (the “Company”) unanimously approved the continuance of the Company’s Advisory Agreement with the Adviser in respect of AB Corporate Income Shares (the “Fund”) at a meeting held in-person on August 1-2, 2023 (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 noted that the Fund is designed as a vehicle for the wrap fee account market (where investors pay fees to a wrap fee sponsor which pays investment fees and expenses from such fee). The directors also noted that no advisory fee is payable by the Fund, that the Advisory Agreement does not include the reimbursement provision for certain administrative expenses included in the advisory agreements of most of the open-end AB Funds, and that the Adviser is responsible for payment of the Fund’s ordinary expenses. The directors noted that the Company acknowledges in the Advisory Agreement that the Adviser and its affiliates expect to receive compensation from third parties in connection with services provided under the Advisory Agreement. The directors further noted that the Adviser receives payments from the wrap fee program sponsors (the “Sponsors”) that use the Fund as an investment vehicle for their clients.

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.

50    ^|    AB CORPORATE INCOME SHARES abfunds.com

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 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 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 2021 and 2022 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. 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.

abfunds.com AB CORPORATE INCOME SHARES    ^|    51

Fall-Out Benefits

The directors considered the other benefits to the Adviser and its affiliates from their relationships with the Fund. The directors noted that the Adviser is compensated by the Sponsors. 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 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 the Fund’s performance against a broad-based securities market index, in each case for the 1-, 3-, 5- and 10-year periods ended May 31, 2023 and (in the case of comparisons with the broad-based securities market index) for the period from inception. The directors were cognizant that the Fund was neither designed nor offered as a standalone investment and was intended to serve solely as a component of certain separately managed accounts (“SMAs”). The Adviser had explained that this attribute made it difficult to select an appropriate benchmark for the Fund. At the directors’ request, the Adviser provided information showing the weighting of the Fund in a current SMA and the overall performance of the SMA versus its stated benchmark. Based on their review, the directors concluded that the Fund’s investment performance was acceptable.

Advisory Fees

The directors considered the advisory fee rate payable by the Fund to the Adviser (zero) and information provided 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 payable by other funds.

The directors noted the unusual arrangements in the Advisory Agreement providing for no advisory fee but were cognizant that the Adviser is indirectly compensated by the Sponsors for its services to the Fund. The directors reviewed the fee arrangements between the Adviser and each of the current Sponsors and noted that such fees were negotiated on an arm’s length basis and were within the range of fees paid by wrap fee sponsors to other advisers of similar funds. While the Adviser’s fee arrangements with the Sponsors vary, the directors acknowledged the Adviser’s view that a portion of such fees (less the expenses of the Fund

52    ^|    AB CORPORATE INCOME SHARES abfunds.com

paid by the Adviser) may reasonably be viewed as compensating the Adviser for advisory services it provides to the Fund (the “implied fee”) and that the Adviser believes that while the Sponsors pay the Adviser different fee rates, the rate of fee attributable to Fund management at the Fund level is the same for all Sponsors. The directors also considered the fee rate schedules used by other registered investment companies that invest in fixed income securities that are advised by the Adviser.

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, on the other. The directors recognized that such information was of limited utility in light of the Fund’s unusual fee arrangement. 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.

The Adviser reviewed with the directors the significantly greater scope of the services it provides to the Fund relative to institutional clients. In this regard, the Adviser noted, among other things, that, compared to institutional 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 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.

The directors did not consider comparative expense information for the Fund because the Fund does not bear ordinary expenses.

Economies of Scale

The directors did not consider the extent to which fee levels in the Advisory Agreement for the Fund reflect economies of scale because the Advisory Agreement does not provide for any compensation to be paid to the

abfunds.com AB CORPORATE INCOME SHARES    ^|    53

Adviser by the Fund and the Fund’s expense ratio is zero. They did note, however, that the fee payable to the Adviser by the current Sponsors declines at a breakpoint based on either individual account sizes or on total assets managed by the Adviser for the Sponsor.

SEMI-ANNUAL REPORT

December 13, 2023

This report provides management’s discussion of fund performance for AB Taxable Multi-Sector Income Shares for the semi-annual reporting period ended October 31, 2023. Please note, shares of this Fund are available only to separately managed accounts or participants in “wrap fee” programs or other investment programs approved by the Adviser.

The Fund’s investment objective is to generate income and price appreciation.

NAV RETURNS AS OF OCTOBER 31, 2023 (unaudited)

	6 Months		12 Months
AB TAXABLE MULTI-SECTOR INCOME SHARES		1.22%		4.85%
Bloomberg US Aggregate ex Government Bond Index		-6.28%		1.01%

INVESTMENT RESULTS

The table above shows the Fund’s performance compared with its benchmark, the Bloomberg US Aggregate ex Government Bond Index, for the six- and 12-month periods ended October 31, 2023.

During both periods, the Fund outperformed the benchmark. In the six-month period, yield-curve positioning was the largest contributor to performance, relative to the benchmark, from an underweight to the two-year part of the yield curve. Security selection contributed from exposure in US municipal bonds, Agency Risk share securities and Investment-grade corporates. Currency decisions did not impact performance during the period.

Over the 12-month period, yield-curve positioning was the greatest contributor to performance, from an underweight to the two-year parts of the curve. Sector allocation contributed positively, due to exposures in municipals, supranationals and mortgage pass throughs. Security selection contributed to performance, primarily from asset-backed securities, investment-grade corporates and high-yield corporates. Currency decisions did not have a meaningful impact on results.

During both periods, the Fund used interest rate swaps for hedging and investment purposes, which detracted from absolute returns. Credit default swaps were used for investment purposes, which added to returns.

MARKET REVIEW AND INVESTMENT STRATEGY

During the six-month period ended October 2023, fixed-income government bond market yields were volatile as investors adjusted their expectations for inflation and economic growth. US Treasury yields led global developed-market yields higher over the period, supported by strong US economic growth in the third calendar quarter, and as the Fed convinced investors that interest rates would stay higher for longer to slow growth. Most developed-market central banks appeared to reach peak interest rates as inflation continued to cool. Government bond returns were negative across all major developed countries, with the largest losses in the US, UK and Canada, while government bonds fell the least in the eurozone as economic growth slowed considerably. Although developed-market investment-grade corporate bonds trailed government bonds, investment-grade corporates in the US outperformed US Treasuries with a smaller loss, while eurozone investment-grade corporates had positive returns and outperformed the negative return of eurozone treasuries. High-yield corporate bonds had positive returns overall and outperformed treasuries in the US and eurozone by a wide margin. Hard-currency emerging-market sovereign bonds outperformed developed-market treasuries. Emerging-market investment-grade and high-yield corporates outperformed respective developed-market returns. Emerging-market local-currency debt trailed other risk sectors as the US dollar gained on almost all currencies.

The Fund’s Senior Investment Management Team (the “Team”) continues to seek attractively priced securities through top-down and bottom-up research, while mitigating overall risk. The Team invests primarily in single-sector, investment-grade issues of global corporates but has leeway to invest in below investment-grade bonds as well.

INVESTMENT POLICIES

The Fund invests, under normal circumstances, at least 80% of its net assets in fixed-income securities. The Fund may invest in a broad range of securities in both developed and emerging markets. The Fund may invest across all fixed-income sectors, including corporate and US and non-US government securities. The Fund may invest up to 50% of its assets in below investment-grade bonds (“junk bonds”). The Fund expects to invest in readily marketable fixed-income securities with a range of maturities from short-to long-term.

The Fund may invest without limit in US dollar-denominated foreign fixed-income securities and may invest up to 50% of its assets in non-US dollar-denominated foreign fixed-income securities. These investments may include, in each case, developed- and emerging-market debt securities.

(continued on next page)

abfunds.com AB TAXABLE MULTI-SECTOR INCOME SHARES     ^|    3

The Adviser selects securities for purchase or sale based on its assessment of the securities’ risk and return characteristics as well as the securities’ impact on the overall risk and return characteristics of the Fund. In making this assessment, the Adviser takes into account various factors, including the credit quality and sensitivity to interest rates of the securities under consideration and of the Fund’s other holdings.

The Fund may also invest in mortgage-related and other asset-backed securities; loan participations; inflation-indexed securities; structured securities; variable-, floating- and inverse-floating-rate instruments; and preferred stock, and may use other investment techniques. The Fund may use leverage for investment purposes. The Fund intends, among other things, to enter into transactions such as reverse repurchase agreements, forward contracts and dollar rolls. The Fund may invest, without limit, in derivatives, such as options, futures contracts, forwards or swap agreements.

Currencies can have a dramatic effect on returns of non-US dollar-denominated fixed-income securities, significantly adding to returns in some years and greatly diminishing them in others. The Adviser evaluates currency and fixed-income positions separately and may seek to hedge the currency exposure resulting from the Fund’s fixed-income securities positions when it finds the currency exposure unattractive. To hedge a portion of its currency risk, the Fund may from time to time invest in currency-related derivatives, including forward currency exchange contracts, futures contracts, options on futures contracts, swaps and options. The Adviser may also seek investment opportunities by taking long or short positions in currencies through the use of currency-related derivatives.

DISCLOSURES AND RISKS

Benchmark Disclosure

The Bloomberg US Aggregate ex Government Bond Index is unmanaged and does not reflect fees and expenses associated with the active management of a fund. The Bloomberg US Aggregate ex Government Bond Index represents the performance of securities within the US investment-grade fixed-rate bond market, with index components for corporate securities, mortgage pass-through securities, asset-backed securities and CMBS. An investor cannot invest directly in an index, and its 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 assets will fluctuate as the stock or bond market fluctuates. 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.

Credit Risk: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security and any accrued interest. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security.

Interest-Rate Risk: Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of existing investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest-rate risk is generally greater for fixed-income securities with longer maturities or durations. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the end of a recent period of historically low rates and the effect of potential central bank monetary policy, and government fiscal policy, initiatives and resulting market reactions to those initiatives.

Duration Risk: Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise.

DISCLOSURES AND RISKS (continued)

Below Investment-Grade Securities Risk: Investments in fixed-income securities with lower ratings (commonly known as “junk bonds”) tend to have a higher probability that an issuer will default or fail to meet its payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest-rate sensitivity, negative perceptions of the junk bond market generally and may be more difficult to trade than other types of securities.

Inflation Risk: This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Fund’s assets can decline as can the value of the Fund’s distributions. This risk is significantly greater for fixed-income securities with longer maturities.

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 more difficult to trade due to adverse market, economic, political, regulatory or other factors.

Emerging-Market Risk: Investments in emerging-market countries may have more risk because the markets are less developed and less liquid as well as being subject to increased economic, political, regulatory or other uncertainties.

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

Mortgage-Related and/or Other Asset-Backed Securities Risk: Investments in mortgage-related and other asset-backed securities are subject to certain additional risks. The value of these securities may be particularly sensitive to changes in interest rates. These risks include “extension risk”, which is the risk that, in periods of rising interest rates, issuers may delay the payment of principal, and “prepayment risk”, which is the risk that in periods of falling interest rates, issuers may pay principal sooner than expected, exposing the Fund to a lower rate of return upon reinvestment of principal. Mortgage-backed securities offered by nongovernmental issuers and other asset-backed securities may be subject to other risks, such as higher rates of default in the mortgages or assets backing the securities or risks associated with the nature and servicing of mortgages or assets backing the securities.

Municipal Market Risk: This is the risk that special factors may adversely affect the value of municipal securities and have a significant effect on the yield or value of the Fund’s investments in municipal securities. These factors include economic conditions, political or legislative changes, public health crises, uncertainties related to the tax status of municipal securities,

DISCLOSURES AND RISKS (continued)

and the rights of investors in these securities. To the extent that the Fund invests more of its assets in a particular state’s municipal securities, the Fund may be vulnerable to events adversely affecting that state, including economic, political and regulatory occurrences, court decisions, terrorism, public health crises (including the occurrence of a contagious disease or illness) and catastrophic natural disasters, such as hurricanes, fires or earthquakes. The Fund’s investments in certain municipal securities with principal and interest payments that are made from the revenues of a specific project or facility, and not general tax revenues, may have increased risks. Factors affecting the project or facility, such as local business or economic conditions, could have a significant effect on the project’s ability to make payments of principal and interest on these securities.

In addition, changes in tax rates or the treatment of income from certain types of municipal securities, among other things, could negatively affect the municipal securities markets.

Sector Risk: The Fund may have more risk because it may invest to a significant extent in one or more particular market sectors. 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.

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

Leverage Risk: To the extent the Fund uses leveraging techniques, its net asset value (“NAV”) may be more volatile because leverage tends to exaggerate the effect of changes in interest rates and any increase or decrease in the value of the Fund’s 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, 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.

EXPENSE EXAMPLE

(unaudited)

As a shareholder of the Fund, you may incur various ongoing non-operating and extraordinary costs. 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 in this line, 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 in the first line 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 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.

	Beginning Account Value May 1, 2023		Ending Account Value October 31, 2023		Expenses Paid During Period*		Annualized Expense Ratio*
Actual	$	1,000	$	1,012.20	$	– 0 –		0.00	%
Hypothetical**	$	1,000	$	1,025.14	$	– 0 –		0.00	%

* Expenses are equal to the Fund’s annualized expense ratio, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). The Fund’s operating expenses are borne by the Adviser or its affiliates.

** Assumes 5% annual return before expenses.

NOTES TO FINANCIAL STATEMENTS

October 31, 2023 (unaudited)

NOTE A

Significant Accounting Policies

AB Corporate Shares (the “Trust”) is registered under the Investment Company Act of 1940 (the “1940 Act”), as an open-end, diversified management investment company. The Trust, which is a Massachusetts Business Trust, operates as a “series” company currently offering five separate portfolios: AB Corporate Income Shares, AB Municipal Income Shares, AB Taxable Multi-Sector Income Shares, AB Impact Municipal Income Shares and AB Tax-Aware Real Return Income Shares. Each portfolio is considered to be a separate entity for financial reporting and tax purposes. This report relates only to AB Taxable Multi-Sector Income Shares (the “Fund”).

Shares of the Fund are offered exclusively to holders of accounts established under wrap fee programs sponsored and maintained by certain registered investment advisers approved by AllianceBernstein L.P. (the “Adviser”). The Fund’s shares may be purchased at the relevant net asset value without a sales charge or other fee. 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 Trust’s Board of Trustees (the “Board”). Pursuant to these procedures, 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 sale on such day, the securities are valued

30    ^|    AB TAXABLE MULTI-SECTOR INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

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

abfunds.com AB TAXABLE MULTI-SECTOR INCOME SHARES     ^|    31

NOTES TO FINANCIAL STATEMENTS (continued)

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)

The fair value of debt instruments, such as bonds, and over-the-counter derivatives is generally based on market price quotations, recently executed market transactions (where observable) or industry recognized modeling techniques and are generally classified as Level 2. Pricing vendor inputs to Level 2 valuations may include quoted prices for similar investments in active markets, interest rate curves, coupon rates, currency rates, yield curves, option adjusted spreads, default rates, credit spreads and other unique security features in order to estimate the relevant cash flows which are then discounted to calculate fair values. If these inputs are unobservable and significant to the fair value, these investments will be classified as Level 3.

Valuations of mortgage-backed or other asset-backed securities, by pricing vendors, are based on both proprietary and industry recognized models

32    ^|    AB TAXABLE MULTI-SECTOR INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

and discounted cash flow techniques. Significant inputs to the valuation of these instruments are value of the collateral, the rates and timing of delinquencies, the rates and timing of prepayments, and default and loss expectations, which are driven in part by housing prices for residential mortgages. Significant inputs are determined based on relative value analyses, which incorporate comparisons to instruments with similar collateral and risk profiles, including relevant indices. Mortgage and asset-backed securities for which management has collected current observable data through pricing services are generally categorized within Level 2. Those investments for which current observable data has not been provided are classified as Level 3.

Other fixed income investments, including non-U.S. government and corporate debt, are generally valued using quoted market prices, if available, which are typically impacted by current interest rates, maturity dates and any perceived credit risk of the issuer. Additionally, in the absence of quoted market prices, these inputs are used by pricing vendors to derive a valuation based upon industry or proprietary models which incorporate issuer specific data with relevant yield/spread comparisons with more widely quoted bonds with similar key characteristics. Those investments for which there are observable inputs are classified as Level 2. Where the inputs are not observable, the investments are classified as Level 3.

The following table summarizes the valuation of the Fund’s investments by the above fair value hierarchy levels as of October 31, 2023:

(a) Other financial instruments include reverse repurchase agreements and 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.

NOTES TO FINANCIAL STATEMENTS (continued)

(b) Only variation margin receivable (payable) at period end is reported within the statement of assets and liabilities. This amount reflects cumulative unrealized appreciation (depreciation) on futures and centrally cleared swaps as reported in the portfolio of investments. Where applicable, centrally cleared swaps with upfront premiums are presented here at market value.

3. 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.

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.

4. 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 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.

5. 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.

NOTE B

Advisory Fee and Other Transactions with Affiliates

Under the terms of the Advisory Agreement, the Fund pays no advisory fee to the Adviser and the Adviser reimburses or pays for the Fund’s operating expenses. The Fund is an integral part of separately managed accounts in

34    ^|    AB TAXABLE MULTI-SECTOR INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

wrap fee programs and other investment programs. Typically, participants in these programs pay a fee to their investment adviser for all costs and expenses of the separately managed account, including costs and expenses associated with the Fund, and a fee is paid by their investment adviser to the Adviser. In certain cases, participants may have a direct relationship with the Adviser without the involvement of a third party investment adviser, in which case the participant would pay a fee directly to the Adviser. The Adviser serves as investment manager and adviser of the Fund and continuously furnishes an investment program for the Fund and manages, supervises and conducts the affairs of the Fund, subject to the supervisions of the Fund’s Board. The Advisory Agreement provides that the Adviser or an affiliate will furnish, or pay the expenses of the Fund for, office space, facilities and equipment, services of executive and other personnel of the Fund and certain administrative services.

The Fund has entered into a distribution agreement with AllianceBernstein Investments, Inc., the Fund’s principal underwriter (the “Underwriter”), to permit the Underwriter to distribute the Fund’s shares, which are sold at their net asset value without any sales charge. The Fund does not pay a fee for this service. The Underwriter is a wholly owned subsidiary of the Adviser.

AllianceBernstein Investor Services, Inc. (“ABIS”), a wholly-owned subsidiary of the Adviser, acts as the Fund’s registrar, transfer agent and dividend-disbursing agent. ABIS registers the transfer, issuance and redemption of Fund shares and disburses dividends and other distributions to Fund shareholders. The Fund does not pay a fee for this service.

The Fund may invest in AB Government Money Market Portfolio (the “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 Government Money Market Portfolio (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 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 Government Money Market Portfolio, the Adviser has contractually agreed to reimburse its advisory fee from the Fund in an amount equal to the Fund’s pro rata share of the effective advisory fee of Government Money Market Portfolio, as borne indirectly by the Fund as an acquired fund fee and expense. For the six months ended October 31, 2023, such reimbursement amounted to $4,888.

Gross unrealized appreciation	$	139,885
Gross unrealized depreciation		(11,565,817	)
Net unrealized depreciation	$	(11,425,932	)

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 principal types of derivatives utilized by the Fund, as well as the methods in which they may be used are:

• Swaps

The Fund may enter into swaps to hedge its exposure to interest rates, credit risk or currencies. The Fund may also enter into swaps for non-hedging purposes as a means of gaining market exposures, making direct investments in foreign currencies, as described below under “Currency Transactions.” A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. The payment flows are usually netted against each other, with the

36    ^|    AB TAXABLE MULTI-SECTOR INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

difference being paid by one party to the other. In addition, collateral may be pledged or received by the Fund in accordance with the terms of the respective swaps to provide value and recourse to the Fund or its counterparties in the event of default, bankruptcy or insolvency by one of the parties to the swap.

Risks may arise as a result of the failure of the counterparty to the swap to comply with the terms of the swap. The loss incurred by the failure of a counterparty is generally limited to the net interim payment to be received by the Fund, and/or the termination value at the end of the contract. Therefore, the Fund considers the creditworthiness of each counterparty to a swap in evaluating potential counterparty risk. This risk is mitigated by having a netting arrangement between the Fund and the counterparty and by the posting of collateral by the counterparty to the Fund to cover the Fund’s exposure to the counterparty. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying securities. The Fund accrues for the interim payments on swaps on a daily basis, with the net amount recorded within unrealized appreciation (depreciation) of swaps on the statement of assets and liabilities, where applicable. Once the interim payments are settled in cash, the net amount is recorded as realized gain/(loss) on swaps on the statement of operations, in addition to any realized gain/(loss) recorded upon the termination of swaps. Upfront premiums paid or received for swaps are recognized as cost or proceeds on the statement of assets and liabilities and are amortized on a straight line basis over the life of the contract. Amortized upfront premiums are included in net realized gain/(loss) from swaps on the statement of operations. Fluctuations in the value of swaps are recorded as a component of net change in unrealized appreciation (depreciation) of swaps on the statement of operations.

Certain standardized swaps, including certain interest rate swaps and credit default swaps, are (or soon will be) subject to mandatory central clearing. Cleared swaps are transacted through futures commission merchants (“FCMs”) that are members of central clearinghouses, with the clearinghouse serving as central counterparty, similar to transactions in futures contracts. Centralized clearing will be required for additional categories of swaps on a phased-in basis based on requirements published by the Securities and Exchange Commission and Commodity Futures Trading Commission.

At the time the Fund enters into a centrally cleared swap, the Fund deposits and maintains as collateral an initial margin with the broker, as required by the clearinghouse on which the transaction is effected. Such amount is shown as cash collateral due from broker on the

abfunds.com AB TAXABLE MULTI-SECTOR INCOME SHARES     ^|    37

NOTES TO FINANCIAL STATEMENTS (continued)

statement of assets and liabilities. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. Risks may arise from the potential inability of a counterparty to meet the terms of the contract. The credit/counterparty risk for centrally cleared swaps is generally less than non-centrally cleared swaps, since the clearinghouse, which is the issuer or counterparty to each centrally cleared swap, has robust risk mitigation standards, including the requirement to provide initial and variation margin. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the time it was closed.

Interest Rate Swaps:

The Fund is subject to interest rate risk exposure in the normal course of pursuing its investment objectives. Because the Fund holds fixed rate bonds, the value of these bonds may decrease if interest rates rise. To help hedge against this risk and to maintain its ability to generate income at prevailing market rates, the Fund may enter into interest rate swaps. Interest rate swaps are agreements between two parties to exchange cash flows based on a notional amount. The Fund may elect to pay a fixed rate and receive a floating rate, or, receive a fixed rate and pay a floating rate on a notional amount.

In addition, the Fund may also enter into interest rate swap transactions to preserve a return or spread on a particular investment or portion of its portfolio, or protecting against an increase in the price of securities the Fund anticipates purchasing at a later date. Interest rate swaps involve the exchange by the Fund with another party of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments) computed based on a contractually-based principal (or “notional”) amount. Interest rate swaps are entered into on a net basis (i.e., the two payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the two payments).

During the six months ended October 31, 2023, the Fund held interest rate swaps for hedging and non-hedging purposes.

Credit Default Swaps:

The Fund may enter into credit default swaps, including to manage its exposure to the market or certain sectors of the market, to reduce its risk exposure to defaults by corporate and sovereign issuers held by the Fund, or to create exposure to corporate or sovereign issuers to which it is not otherwise exposed. The Fund may purchase credit protection (“Buy Contract”) or provide credit protection (“Sale

38    ^|    AB TAXABLE MULTI-SECTOR INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

Contract”) on the referenced obligation of the credit default swap. During the term of the swap, the Fund receives/(pays) fixed payments from/(to) the respective counterparty, calculated at the agreed upon rate applied to the notional amount. If the Fund is a buyer/(seller) of protection and a credit event occurs, as defined under the terms of the swap, the Fund will either (i) receive from the seller/(pay to the buyer) of protection an amount equal to the notional amount of the swap (the “Maximum Payout Amount”) and deliver/(take delivery of) the referenced obligation or (ii) receive/(pay) a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation. In certain circumstances Maximum Payout Amounts may be partially offset by recovery values of the respective referenced obligations, upfront premium received upon entering into the agreement, or net amounts received from settlement of buy protection credit default swaps entered into by the Fund for the same referenced obligations with the same counterparty.

Credit default swaps may involve greater risks than if the Fund had invested in the referenced obligation directly. Credit default swaps are subject to general market risk, liquidity risk, counterparty risk and credit risk. If the Fund is a buyer of protection and no credit event occurs, it will lose the payments it made to its counterparty. If the Fund is a seller of protection and a credit event occurs, the value of the referenced obligation received by the Fund coupled with the periodic payments previously received, may be less than the Maximum Payout Amount it pays to the buyer, resulting in a net loss to the Fund.

Implied credit spreads over U.S. Treasuries of comparable maturity utilized in determining the market value of credit default swaps on issuers as of period end are disclosed in the portfolio of investments. The implied spreads serve as an indicator of the current status of the payment/performance risk and typically reflect the likelihood of default by the issuer of the referenced obligation. The implied credit spread of a particular reference obligation also reflects the cost of buying/selling protection and may reflect upfront payments required to be made to enter into the agreement. Widening credit spreads typically represent a deterioration of the referenced obligation’s credit soundness and greater likelihood of default or other credit event occurring as defined under the terms of the agreement. A credit spread identified as “Defaulted” indicates a credit event has occurred for the referenced obligation.

During the six months ended October 31, 2023, the Fund held credit default swaps for hedging purposes.

NOTES TO FINANCIAL STATEMENTS (continued)

The Fund typically enters into International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreement”) with its OTC derivative contract counterparties in order to, among other things, reduce its credit risk to OTC counterparties. ISDA Master Agreements include provisions for general obligations, representations, collateral and events of default or termination. Under an ISDA Master Agreement, the Fund typically may offset with the OTC counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment (close-out netting) in the event of default or termination. In the event of a default by an OTC counterparty, the return of collateral with market value in excess of the Fund’s net liability, held by the defaulting party, may be delayed or denied.

The Fund’s ISDA Master Agreements may contain provisions for early termination of OTC derivative transactions in the event the net assets of the Fund decline below specific levels (“net asset contingent features”). If these levels are triggered, the Fund’s OTC counterparty has the right to terminate such transaction and require the Fund to pay or receive a settlement amount in connection with the terminated transaction. If OTC derivatives were held at period end, please refer to netting arrangements by the OTC counterparty table below for additional details.

During the six months ended October 31, 2023, the Fund had entered into the following derivatives:

	Asset Derivatives		Liability Derivatives
Derivative Type	Statement of Assets and Liabilities Location	Fair Value	Statement of Assets and Liabilities Location	Fair Value
Interest rate contracts			Payable for variation margin on centrally cleared swaps	$	1,828,919	*
Credit contracts			Market value on credit default swaps		223,957
Total				$	2,052,876

* Only variation margin receivable/payable at period end is reported within the statement of assets and liabilities. This amount reflects cumulative unrealized appreciation (depreciation) on futures and centrally cleared swaps as reported in the portfolio of investments.

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

Risks Involved in Investing in the Fund

Market Risk—The value of the Fund’s assets will fluctuate as the stock or bond market fluctuates. 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.

Credit Risk—An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security and any accrued interest. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security.

42    ^|    AB TAXABLE MULTI-SECTOR INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

Interest-Rate Risk—Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of existing investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest-rate risk is generally greater for fixed-income securities with longer maturities or durations. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the recent end of a period of historically low rates and the effects of potential central bank monetary policy, and government fiscal policy, initiatives and market reactions to those initiatives.

Duration Risk—Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to the full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise.

Below Investment-Grade Securities Risk—Investments in fixed-income securities with lower ratings (commonly known as “junk bonds”) tend to have a higher probability that an issuer will default or fail to meet its payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity and negative perceptions of the junk bond market generally and may be more difficult to trade than other types of securities.

Inflation Risk—This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Fund’s assets can decline, as can the value of the Fund’s distributions. This risk is significantly greater for fixed-income securities with longer maturities.

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.

Emerging-Market Risk—Investments in emerging market countries may have more risk because the markets are less developed and less liquid as well as being subject to increased economic, political, regulatory or other uncertainties.

Currency Risk—Fluctuations in currency exchange rates may negatively affect the value of the Fund’s investments or reduce its returns.

abfunds.com AB TAXABLE MULTI-SECTOR INCOME SHARES     ^|    43

NOTES TO FINANCIAL STATEMENTS (continued)

Mortgage-Related and/or Other Asset-Backed Securities Risk—Investments in mortgage-related and other asset-backed securities are subject to certain additional risks. The value of these securities may be particularly sensitive to changes in interest rates. These risks include “extension risk”, which is the risk that, in periods of rising interest rates, issuers may delay the payment of principal, and “prepayment risk”, which is the risk that in periods of falling interest rates, issuers may pay principal sooner than expected, exposing the Fund to a lower rate of return upon reinvestment of principal. Mortgage-backed securities offered by non-governmental issuers and other asset-backed securities may be subject to other risks, such as higher rates of default in the mortgages or assets backing the securities or risks associated with the nature and servicing of mortgages or assets backing the securities.

Municipal Market Risk—This is the risk that special factors may adversely affect the value of municipal securities and have a significant effect on the yield or value of the Fund’s investments in municipal securities. These factors include economic conditions, political or legislative changes, public health crises, uncertainties related to the tax status of municipal securities, and the rights of investors in these securities. To the extent that the Fund invests more of its assets in a particular state’s municipal securities, the Fund may be vulnerable to events adversely affecting that state, including economic, political and regulatory occurrences, court decisions, terrorism, public health crises (including the occurrence of a contagious disease or illness) and catastrophic natural disasters, such as hurricanes, fires or earthquakes. The Fund’s investments in certain municipal securities with principal and interest payments that are made from the revenues of a specific project or facility, and not general tax revenues, may have increased risks. Factors affecting the project or facility, such as local business or economic conditions, could have a significant effect on the project’s ability to make payments of principal and interest on these securities.

In addition, changes in tax rates or the treatment of income from certain types of municipal securities, among other things, could negatively affect the municipal securities markets.

Sector Risk—The Fund may have more risk because it may invest to a significant extent in one or more particular market sectors. 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.

Derivatives Risk—Derivatives may be difficult to price or unwind and leveraged so that small changes may produce disproportionate losses for the Fund. A short position in a derivative instrument involves the risk of a theoretically unlimited increase in the value of the underlying asset, which

44    ^|    AB TAXABLE MULTI-SECTOR INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

could cause the Fund to suffer a potentially unlimited loss. Derivatives, especially over-the-counter derivatives, are also subject to counterparty risk, which is the risk that the counterparty (the party on the other side of the transaction) on a derivative transaction will be unable or unwilling to honor its contractual obligations to the Fund.

Leverage Risk—When the Fund borrows money or otherwise leverages its investments, its performance may be volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s investments. The Fund may create leverage through the use of reverse repurchase arrangements, forward currency exchange contracts, forward commitments, dollar rolls or futures or by borrowing money. The use of other types of derivative instruments by the Fund, such as options and swaps, may also result in a form of leverage. Leverage may result in higher returns to the Fund than if the Fund were not leveraged, but may also adversely affect returns, particularly if the market is declining.

LIBOR Replacement Risk—The Fund may be exposed to debt securities, derivatives or other financial instruments that recently transitioned from the London Interbank Offered Rate, or “LIBOR,” as a “benchmark” or “reference rate” for various interest rate calculations. LIBOR’s administrator, ICE Benchmark Administration, ceased publishing most LIBOR settings (including some U.S. LIBOR settings) by the end of 2021 and the remaining (and most widely used) U.S. Dollar LIBOR settings after June 30, 2023. The United Kingdom Financial Conduct Authority, which regulates LIBOR, will permit the use of synthetic U.S. Dollar LIBOR rates for non-U.S. contracts through September 30, 2024, but any such rates would be considered non-representative of the underlying market. Since 2018 the Federal Reserve Bank of New York has published the Secured Overnight Financing Rate (referred to as SOFR), which is intended to replace U.S. Dollar LIBOR. SOFR is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities in the repurchase agreement (repo) market. There is no assurance that the composition or characteristics of SOFR or any such alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that the market for SOFR-linked financial instruments will have the same volume or liquidity as did the market for LIBOR-linked financial instruments prior to LIBOR’s discontinuance or unavailability. Neither the long-term effects of the LIBOR transition process nor its ultimate success can yet be known.

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

abfunds.com AB TAXABLE MULTI-SECTOR INCOME SHARES     ^|    45

NOTES TO FINANCIAL STATEMENTS (continued)

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, 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 F

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 October 31, 2023.

NOTE G

Distributions to Shareholders

The tax character of distributions to be paid for the year ending April 30, 2024 will be determined at the end of the current fiscal year. The tax character of distributions paid during the fiscal years ended April 30, 2023 and April 30, 2022 were as follows:

	2023		2022
Distributions paid from:
Ordinary income	$	7,510,630	$	3,392,140
Net long-term capital gains		487,295		1,412,066
Total taxable distributions paid	$	7,997,925	$	4,804,206

As of April 30, 2023, the components of accumulated earnings (deficit) on a tax basis were as follows:

Undistributed ordinary income	$	898,596
Accumulated capital and other losses		(2,978,009	)(a)
Unrealized appreciation (depreciation)		(8,730,221	)(b)
Total accumulated earnings (deficit)	$	(10,809,634	)(c)

(a) As of April 30, 2023, the Fund had a net capital loss carryforward of $2,978,009.

(b) The differences between book-basis and tax-basis unrealized appreciation (depreciation) are attributable primarily to the tax treatment of callable bonds, the tax treatment of swaps, and the tax deferral of losses on wash sales.

(c) The difference between book-basis and tax-basis components of accumulated earnings (deficit) is attributable primarily to dividends payable.

46    ^|    AB TAXABLE MULTI-SECTOR INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

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 April 30, 2023, the Fund had a net short-term capital loss carryforward of $2,978,009, which may be carried forward for an indefinite period.

Recent Accounting Pronouncements

In December 2022, the Financial Accounting Standards Board issued an Accounting Standards Update, ASU 2022-06, “Reference Rate Reform (Topic 848) – Deferral of the Sunset Date of Topic 848”. ASU 2022-06 is an amendment to ASU 2020-04, which provided optional guidance to ease the potential accounting burden due to the discontinuation of the LIBOR and other interbank-offered based reference rates and which was effective as of March 12, 2020 through December 31, 2022. ASU 2022-06 extends the effective period through December 31, 2024. Management is currently evaluating the impact, if any, of applying ASU 2022-06.

NOTE I

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.

Operation and Effectiveness of the Fund’s Liquidity Risk Management Program:

In October 2016, the Securities and Exchange Commission (“SEC”) adopted the open-end fund liquidity rule (the “Liquidity Rule”). In June 2018 the SEC adopted a requirement that funds disclose information about the operation and effectiveness of their Liquidity Risk Management Program (“LRMP”) in their reports to shareholders.

One of the requirements of the Liquidity Rule is for the Fund to designate an Administrator of the Fund’s Liquidity Risk Management Program. The Administrator of the Fund’s LRMP is AllianceBernstein L.P., the Fund’s investment adviser (the “Adviser”). The Adviser has delegated the responsibility to its Liquidity Risk Management Committee (the “Committee”).

Another requirement of the Liquidity Rule is for the Fund’s Board of Trustees (the “Fund Board”) to receive an annual written report from the Administrator of the LRMP, which addresses the operation of the Fund’s LRMP and assesses its adequacy and effectiveness. The Adviser provided the Fund Board with such annual report during the first quarter of 2023, which covered the period January 1, 2022 through December 31, 2022 (the “Program Reporting Period”).

The LRMP’s principal objectives include supporting the Fund’s compliance with limits on investments in illiquid assets and mitigating the risk that the Fund will be unable to meet its redemption obligations in a timely manner.

Pursuant to the LRMP, the Fund classifies the liquidity of its portfolio investments into one of the four categories defined by the SEC: Highly Liquid, Moderately Liquid, Less Liquid, and Illiquid. These classifications are reported to the SEC on Form N-PORT.

During the Program Reporting Period, the Committee reviewed whether the Fund’s strategy is appropriate for an open-end structure, incorporating any holdings of less liquid and illiquid assets. If the Fund participated in derivative transactions, the exposure from such transactions were considered in the LRMP.

The Committee also performed an analysis to determine whether the Fund is required to maintain a Highly Liquid Investment Minimum (“HLIM”). The Committee also incorporated the following information when determining the Fund’s reasonably anticipated trading size for purposes of liquidity monitoring: historical net redemption activity, a Fund’s concentration in an issuer, shareholder concentration, investment performance, total net assets, and distribution channels.

The Adviser informed the Fund Board that the Committee believes the Fund’s LRMP is adequately designed, has been implemented as intended,

50    ^|    AB TAXABLE MULTI-SECTOR INCOME SHARES abfunds.com

and has operated effectively since its inception. No material exceptions have been noted since the implementation of the LRMP. During the Program Reporting Period, liquidity in all markets was challenged due to rising rates and economic uncertainty. However, markets also remained orderly during the Program Reporting Period. There were no liquidity events that impacted the Fund or its ability to timely meet redemptions during the Program Reporting Period.

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

The disinterested trustees (the “directors”) of AB Corporate Shares (the “Company”) unanimously approved the continuance of the Company’s Advisory Agreement with the Adviser in respect of AB Taxable Multi-Sector Income Shares (the “Fund”) at a meeting held in-person on August 1-2, 2023 (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 noted that the Fund is designed as a vehicle for the wrap fee account market (where investors pay fees to a wrap fee sponsor which pays investment fees and expenses from such fee). The directors also noted that no advisory fee is payable by the Fund, that the Advisory Agreement does not include the reimbursement provision for certain administrative expenses included in the advisory agreements of most of the open-end AB Funds, and that the Adviser is responsible for payment of the Fund’s ordinary expenses. The directors noted that the Company acknowledges in the Advisory Agreement that the Adviser and its affiliates expect to receive compensation from third parties in connection with services provided under the Advisory Agreement. The directors further noted that the Adviser receives payments from the wrap fee program sponsors (the “Sponsors”) that use the Fund as an investment vehicle for their clients.

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.

52    ^|    AB TAXABLE MULTI-SECTOR INCOME SHARES abfunds.com

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 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 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 2021 and 2022 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. 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.

abfunds.com AB TAXABLE MULTI-SECTOR INCOME SHARES     ^|    53

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. The directors noted that the Adviser is compensated by the Sponsors. The directors understood that the Adviser also might derive reputational and other benefits from its association with the Fund.

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 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 the Fund’s performance against a broad-based securities market index, in each case for the 1-, 3-, 5- and 10-year periods ended May 31, 2023 and (in the case of comparisons with the broad-based securities market index) for the period from inception. The directors were cognizant that the Fund was neither designed nor offered as a standalone investment and was intended to serve solely as a component of certain separately managed accounts (“SMAs”). The Adviser had explained that this attribute made it difficult to select an appropriate benchmark for the Fund. At the directors’ request, the Adviser provided information showing the weighting of the Fund in a current SMA and the overall performance of the SMA versus its stated benchmark. Based on their review, the directors concluded that the Fund’s investment performance was acceptable.

Advisory Fees

The directors considered the advisory fee rate payable by the Fund to the Adviser (zero) and information provided 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 payable by other funds.

The directors noted the unusual arrangements in the Advisory Agreement providing for no advisory fee but were cognizant that the Adviser is indirectly compensated by the Sponsors for its services to the Fund. The directors reviewed the fee arrangements between the Adviser and each of the current Sponsors and noted that such fees were negotiated on an arm’s length basis and were within the range of fees paid by wrap fee sponsors to other advisers of similar funds. While the Adviser’s fee arrangements with the Sponsors vary, the directors acknowledged the

54    ^|    AB TAXABLE MULTI-SECTOR INCOME SHARES abfunds.com

Adviser’s view that a portion of such fees (less the expenses of the Fund paid by the Adviser) may reasonably be viewed as compensating the Adviser for advisory services it provides to the Fund (the “implied fee”) and that the Adviser believes that while the Sponsors pay the Adviser different fee rates, the rate of fee attributable to Fund management at the Fund level is the same for all Sponsors. The directors also considered the fee rate schedules used by other registered investment companies that invest in fixed income securities that are advised by the Adviser.

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 recognized that such information was of limited utility in light of the Fund’s unusual fee arrangement. 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. The directors also compared the advisory fee rate for the Fund with that for another fund advised by the Adviser utilizing similar investment strategies.

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.

The directors did not consider comparative expense information for the Fund because the Fund does not bear ordinary expenses.

Economies of Scale

The directors did not consider the extent to which fee levels in the Advisory Agreement for the Fund reflect economies of scale because the Advisory Agreement does not provide for any compensation to be paid to the Adviser by the Fund and the Fund’s expense ratio is zero. They did note, however, that the fee payable to the Adviser by the current Sponsors declines at a breakpoint based on either individual account sizes or on total assets managed by the Adviser for the Sponsor.

SEMI-ANNUAL REPORT

December 20, 2023

This report provides management’s discussion of fund performance for AB Municipal Income Shares for the semi-annual reporting period ended October 31, 2023. Please note, shares of this Fund are available only to separately managed accounts or participants in “wrap fee” programs or other investment programs approved by the Adviser.

The investment objective of the Fund is to earn the highest level of current income, exempt from federal taxation, that is available consistent with what the Adviser considers to be an appropriate level of risk.

NAV RETURNS AS OF OCTOBER 31, 2023 (unaudited)

	6 Months		12 Months
AB MUNICIPAL INCOME SHARES		-7.27%		1.42%
Bloomberg Municipal Bond Index		-4.65%		2.64%

INVESTMENT RESULTS

The table above shows the Fund’s performance compared with its benchmark, the Bloomberg Municipal Bond Index, for the six- and 12-month periods ended October 31, 2023.

For the six-month period, the Fund underperformed the benchmark. An overweight to municipal credit and yield-curve positioning detracted, relative to the benchmark. Sector allocation to senior living and industrial development contributed to performance.

For the 12-month period, the Fund underperformed the benchmark. An overweight to municipal credit and yield-curve positioning detracted from performance, while sector allocation to tobacco and industrial development contributed.

The Fund used derivatives for hedging purposes in the form of interest rate swaps, which added to absolute performance for both periods, as well as Consumer Price Index swaps, which had no material impact for either period.

MARKET REVIEW AND INVESTMENT STRATEGY

For the six-month period ending October 31, 2023, the yield on a 10-Year AAA municipal bond rose to 3.61% from 2.36% and the yield on the 10-Year US Treasury rose to 4.91% from 3.60%. After-tax spreads compressed over the period, which indicated the municipals became more expensive relative to Treasuries. However, worries that the US Federal

2    ^|    AB MUNICIPAL INCOME SHARES abfunds.com

Reserve would continue its policy tightening stance longer than anticipated caused a sell-off during the period and was a headwind to performance.

The Fund’s Senior Investment Management Team relies on an investment process that combines quantitative and fundamental research to build effective municipal bond portfolios.

The Fund may purchase municipal securities that are insured under policies issued by certain insurance companies. Historically, insured municipal securities typically received a higher credit rating, which meant that the issuer of the securities paid a lower interest rate. As a result of declines in the credit quality and associated downgrades of most bond insurers, insurance has less value than it did in the past. In purchasing such insured securities, the Adviser evaluates the risk and return of municipal securities through its own research. If an insurance company’s rating is downgraded or the company becomes insolvent, the prices of municipal securities insured by the insurance company may decline. As of October 31, 2023, the Fund’s percentages of investments in municipal bonds that are insured and in insured municipal bonds that have been pre-refunded or escrowed to maturity were 2.49% and 0.00%, respectively.

INVESTMENT POLICIES

The Fund pursues its objective by investing principally in high-yielding municipal securities that may be noninvestment grade or investment-grade. As a matter of fundamental policy, the Fund invests, under normal circumstances, at least 80% of its net assets in municipal securities that pay interest that is exempt from federal income tax. These securities may pay interest that is subject to the federal alternative minimum tax for certain taxpayers.

The Adviser selects securities for purchase or sale based on its assessment of the securities’ risk and return characteristics as well as the securities’ impact on the overall risk and return characteristics of the Fund. In making this assessment, the Adviser takes into account various factors, including the credit quality and sensitivity to interest rates of the securities under consideration and of the Fund’s other holdings.

The Fund may invest without limit in lower-rated securities (“junk bonds”), which may include securities having the lowest rating, and in unrated securities that, in the Adviser’s judgment, would be lower-rated

securities if rated. The Fund may invest in fixed-income securities with any maturity or duration. The Fund will seek to increase income for shareholders by investing in longer maturity bonds. Consistent with its

(continued on next page)

abfunds.com AB MUNICIPAL INCOME SHARES    ^|    3

objective of seeking a higher level of income, the Fund may experience greater volatility and a higher risk of loss of principal than other municipal funds.

The Fund may also invest in tender option bond transactions (“TOBs”); forward commitments; zero-coupon municipal securities and variable-, floating- and inverse-floating-rate municipal securities; certain types of mortgage-related securities; and derivatives, such as options, futures contracts, forwards and swaps.

The Fund may make short sales of securities or maintain a short position, and may use other investment techniques. The Fund may use leverage for investment purposes to increase income through the use of TOBs and derivative instruments, such as interest rate swaps.

DISCLOSURES AND RISKS

Benchmark Disclosure

The Bloomberg Municipal Bond Index is unmanaged and does not reflect fees and expenses associated with the active management of a fund. The Bloomberg Municipal Bond Index represents the performance of the long-term tax-exempt bond market consisting of investment-grade bonds. An investor cannot invest directly in an index, and its 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 assets will fluctuate as the stock or bond market fluctuates. 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.

Credit Risk: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security and any accrued interest. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.

Municipal Market Risk: This is the risk that special factors may adversely affect the value of municipal securities and have a significant effect on the yield or value of the Fund’s investments in municipal securities. These factors include economic conditions, political or legislative changes, public health crises, uncertainties related to the tax status of municipal securities, and the rights of investors in these securities. To the extent that the Fund invests more of its assets in a particular state’s municipal securities, the Fund may be vulnerable to events adversely affecting that state, including economic, political and regulatory occurrences, court decisions, terrorism, public health crises (including the occurrence of a contagious disease or illness) and catastrophic natural disasters, such as hurricanes, fires or earthquakes. The Fund’s investments in certain municipal securities with principal and interest payments that are made from the revenues of a specific project or facility, and not general tax revenues, may have increased risks. Factors affecting the project or facility, such as local business or economic conditions, could have a significant effect on the project’s ability to make payments of principal and interest on these securities.

abfunds.com AB MUNICIPAL INCOME SHARES    ^|    5

DISCLOSURES AND RISKS (continued)

In addition, changes in tax rates or the treatment of income from certain types of municipal securities, among other things, could negatively affect the municipal securities markets.

Tax Risk: There is no guarantee that all of the Fund’s income will remain exempt from federal or state income taxes. From time to time, the US government and the US Congress consider changes in federal tax law that could limit or eliminate the federal tax exemption for municipal bond income, which would in effect reduce the income received by shareholders from the Fund by increasing taxes on that income. In such event, the Fund’s net asset value (“NAV”) could also decline as yields on municipal bonds, which are typically lower than those on taxable bonds, would be expected to increase to approximately the yield of comparable taxable bonds. Actions or anticipated actions affecting the tax-exempt status of municipal bonds could also result in significant shareholder redemptions of Fund shares as investors anticipate adverse effects on the Fund or seek higher yields to offset the potential loss of the tax deduction. As a result, the Fund would be required to maintain higher levels of cash to meet the redemptions, which would negatively affect the Fund’s yield. The federal income tax treatment of payments in respect of certain derivative contracts is unclear.

Below Investment-Grade Securities Risk: Investments in fixed-income securities with lower ratings (commonly known as “junk bonds”) tend to have a higher probability that an issuer will default or fail to meet its payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest-rate sensitivity and negative perceptions of the junk bond market generally and may be more difficult to trade than other types of securities.

Interest-Rate Risk: Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of existing investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest-rate risk is generally greater for fixed-income securities with longer maturities or durations. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the end of a recent period of historically low rates and the effect of potential central bank monetary policy, and government fiscal policy initiatives and resulting market reactions to those initiatives.

Duration Risk: Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise.

6    ^|    AB MUNICIPAL INCOME SHARES abfunds.com

DISCLOSURES AND RISKS (continued)

Inflation Risk: This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Fund’s assets can decline as can the value of the Fund’s distributions. This risk is significantly greater for fixed-income securities with longer maturities.

Leverage Risk: To the extent the Fund uses leveraging techniques, its NAV may be more volatile because leverage tends to exaggerate the effect of changes in interest rates and any increase or decrease in the value of the Fund’s investments.

Illiquid Investments Risk: Illiquid investments risk exists when particular investments, such as lower-rated securities, are or become difficult to purchase or sell, possibly preventing the Fund from selling such investments at an advantageous price. The Fund is subject to illiquid investments risk because the market for municipal securities is generally smaller than many other markets. Derivatives and securities involving substantial market and credit risk tend to involve greater illiquid investments risk than most other types of investments.

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

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

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

EXPENSE EXAMPLE

(unaudited)

As a shareholder of the Fund, you may incur various ongoing non-operating and extraordinary costs. 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 in this line, 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 in the first line 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 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.

	Beginning Account Value May 1, 2023		Ending Account Value October 31, 2023		Expenses Paid During Period*		Annualized Expense Ratio*
Actual	$	1,000	$	927.30	$	0.97		0.20	%
Hypothetical**	$	1,000	$	1,024.13	$	1.02		0.20	%

* Expenses are equal to the Fund’s annualized expense ratio (interest expense incurred) multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). The Fund’s operating expenses are borne by the Adviser or its affiliates.

** Assumes 5% annual return before expenses.

PORTFOLIO SUMMARY

October 31, 2023 (unaudited)

PORTFOLIO STATISTICS

Net Assets ($mil): $9,525.8

1 The Fund’s quality rating breakdown is expressed as a percentage of the Fund’s total investments in municipal securities and may vary over time. The Fund also enters into derivative transactions, which may be used for hedging or investment purposes (see “Portfolio of Investments” section of the report for additional details). The quality ratings are determined by using the S&P Global Ratings (“S&P”), Moody’s Investors Services, Inc.(“Moody’s”) and Fitch Ratings, Ltd.(“Fitch”). The Fund considers the credit ratings issued by S&P, Moody’s and Fitch and uses the highest rating issued by the agencies. These ratings are a measure of the quality and safety of a bond or portfolio, based on the issuer’s financial condition. AAA is the highest (best) and D is the lowest (worst). If applicable, the pre-refunded category includes bonds which are secured by U.S. Government securities and therefore are deemed high-quality investment-grade by the Adviser. If applicable, Not Applicable (N/A) includes non-creditworthy investments such as equities, currency contracts, futures and options. If applicable, the Not Rated category includes bonds that are not rated by a nationally recognized statistical rating organization. The Adviser evaluates the creditworthiness of non-rated securities based on a number of factors including, but not limited to, cash flows, enterprise value and economic environment.

AB Corporate Shares (the “Trust”) is registered under the Investment Company Act of 1940 (the “1940 Act”), as an open-end, diversified management investment company. The Trust, which is a Massachusetts Business Trust, operates as a “series” company currently offering five separate portfolios: AB Corporate Income Shares, AB Municipal Income Shares, AB Taxable Multi-Sector Income Shares, AB Impact Municipal Income Shares and AB Tax-Aware Real Return Income Shares. Each portfolio is considered to be a separate entity for financial reporting and tax purposes. This report relates only to AB Municipal Income Shares (the “Fund”).

Shares of the Fund are offered exclusively to holders of accounts established under wrap fee programs sponsored and maintained by certain registered investment advisers approved by AllianceBernstein L.P. (the “Adviser”). The Fund’s shares may be purchased at the relevant net asset value without a sales charge or other fee. 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 Trust’s Board of Trustees (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 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

126    ^|    AB MUNICIPAL INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

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)

The fair value of debt instruments, such as bonds, and over-the-counter derivatives is generally based on market price quotations, recently executed market transactions (where observable) or industry recognized modeling techniques and are generally classified as Level 2. Pricing vendor inputs to Level 2 valuations may include quoted prices for similar investments in active markets, interest rate curves, coupon rates, currency rates, yield curves, option adjusted spreads, default rates, credit spreads and other unique security features in order to estimate the relevant cash flows which are then discounted to calculate fair values. If these inputs are unobservable and significant to the fair value, these investments will be classified as Level 3.

Valuations of mortgage-backed or other asset-backed securities, by pricing vendors, are based on both proprietary and industry recognized models and discounted cash flow techniques. Significant inputs to the valuation of these instruments are value of the collateral, the rates and timing of delinquencies, the rates and timing of prepayments, and default and loss expectations, which are driven in part by housing prices for residential

NOTES TO FINANCIAL STATEMENTS (continued)

mortgages. Significant inputs are determined based on relative value analyses, which incorporate comparisons to instruments with similar collateral and risk profiles, including relevant indices. Mortgage and assetbacked securities for which management has collected current observable data through pricing services are generally categorized within Level 2. Those investments for which current observable data has not been provided are classified as Level 3.

Other fixed income investments, including non-U.S. government and corporate debt, are generally valued using quoted market prices, if available, which are typically impacted by current interest rates, maturity dates and any perceived credit risk of the issuer. Additionally, in the absence of quoted market prices, these inputs are used by pricing vendors to derive a valuation based upon industry or proprietary models which incorporate issuer specific data with relevant yield/spread comparisons with more widely quoted bonds with similar key characteristics. Those investments for which there are observable inputs are classified as Level 2. Where the inputs are not observable, the investments are classified as Level 3.

The following table summarizes the valuation of the Fund’s investments by the above fair value hierarchy levels as of October 31, 2023:

	Level 1			Level 2			Level 3			Total

NOTES TO FINANCIAL STATEMENTS (continued)

(c) Other financial instruments include reverse repurchase agreements and 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.

(d) Only variation margin receivable (payable) at period end is reported within the statement of assets and liabilities. This amount reflects cumulative unrealized appreciation (depreciation) on futures and centrally cleared swaps as reported in the portfolio of investments. Where applicable, centrally cleared swaps with upfront premiums are presented here at market value.

3. 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.

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.

4. 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 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.

5. 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.

NOTE B

Advisory Fee and Other Transactions with Affiliates

Under the terms of the advisory agreement, the Fund pays no advisory fee to the Adviser and the Adviser reimburses or pays for the Fund’s operating expenses. The Fund is an integral part of separately managed accounts in wrap fee programs and other investment programs. Typically, participants in these programs pay a fee to their investment adviser for all costs and expenses of the separately managed account, including costs and expenses associated with the Fund, and a fee is paid by their investment adviser to the Adviser. In certain cases, participants may have a direct relationship with the Adviser without the involvement of a third party investment adviser, in which case the participant would pay a fee directly to the Adviser. The Adviser serves as investment manager and adviser of the Fund and continuously furnishes an investment program for the Fund and manages, supervises and conducts the affairs of the Fund, subject to the supervisions of the Fund’s Board. The advisory agreement provides that the Adviser or an affiliate will furnish, or pay the expenses of the Fund for, office space, facilities and equipment, services of executive and other personnel of the Fund and certain administrative services.

The Fund has entered into a distribution agreement with AllianceBernstein Investments, Inc., the Fund’s principal underwriter (the “Underwriter”), to permit the Underwriter to distribute the Fund’s shares, which are sold at their net asset value without any sales charge. The Fund does not pay a fee for this service. The Underwriter is a wholly owned subsidiary of the Adviser.

AllianceBernstein Investor Services, Inc. (“ABIS”), a wholly-owned subsidiary of the Adviser, acts as the Fund’s registrar, transfer agent and dividend-disbursing agent. ABIS registers the transfer, issuance and redemption of Fund shares and disburses dividends and other distributions to Fund shareholders. The Fund does not pay a fee for this service.

The Fund may invest in AB Government Money Market Portfolio (the “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 Government Money Market Portfolio (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 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 Government Money Market Portfolio, the Adviser has contractually agreed to reimburse the Fund in an amount

abfunds.com AB MUNICIPAL INCOME SHARES    ^|    131

NOTES TO FINANCIAL STATEMENTS (continued)

equal to the Fund’s pro rata share of the effective advisory fee of Government Money Market Portfolio, as borne indirectly by the Fund as an acquired fund fee and expense. For the six months ended October 31, 2023, such reimbursement amounted to $44,452.

A summary of the Fund’s transactions in AB mutual funds for the six months ended October 31, 2023 is as follows:

Fund	Market Value 4/30/23 (000)		Purchases at Cost (000)		Sales Proceeds (000)		Market Value 10/31/23 (000)		Dividend Income (000)

U.S. government securities		– 0	–		– 0	–

The cost of investments for federal income tax purposes was substantially the same as the cost for financial reporting purposes. Accordingly, gross unrealized appreciation and unrealized depreciation are as follows:

Gross unrealized appreciation	$	197,950,477
Gross unrealized depreciation		(1,542,839,348	)
Net unrealized depreciation	$	(1,344,888,871	)

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 principal types of derivatives utilized by the Fund, as well as the methods in which they may be used are:

• Swaps

The Fund may enter into swaps to hedge its exposure to interest rates or credit risk. A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a

132    ^|    AB MUNICIPAL INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

specified amount of an underlying asset. The payment flows are usually netted against each other, with the difference being paid by one party to the other. In addition, collateral may be pledged or received by the Fund in accordance with the terms of the respective swaps to provide value and recourse to the Fund or its counterparties in the event of default, bankruptcy or insolvency by one of the parties to the swap.

Risks may arise as a result of the failure of the counterparty to the swap to comply with the terms of the swap. The loss incurred by the failure of a counterparty is generally limited to the net interim payment to be received by the Fund, and/or the termination value at the end of the contract. Therefore, the Fund considers the creditworthiness of each counterparty to a swap in evaluating potential counterparty risk. This risk is mitigated by having a netting arrangement between the Fund and the counterparty and by the posting of collateral by the counterparty to the Fund to cover the Fund’s exposure to the counterparty. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying securities. The Fund accrues for the interim payments on swaps on a daily basis, with the net amount recorded within unrealized appreciation/depreciation of swaps on the statement of assets and liabilities, where applicable. Once the interim payments are settled in cash, the net amount is recorded as realized gain/(loss) on swaps on the statement of operations, in addition to any realized gain/(loss) recorded upon the termination of swaps. Upfront premiums paid or received for swaps are recognized as cost or proceeds on the statement of assets and liabilities and are amortized on a straight line basis over the life of the contract. Amortized upfront premiums are included in net realized gain/(loss) from swaps on the statement of operations. Fluctuations in the value of swaps are recorded as a component of net change in unrealized appreciation/depreciation of swaps on the statement of operations.

Certain standardized swaps, including certain interest rate swaps and credit default swaps, are (or soon will be) subject to mandatory central clearing. Cleared swaps are transacted through futures commission merchants (“FCMs”) that are members of central clearinghouses, with the clearinghouse serving as central counterparty, similar to transactions in futures contracts. Centralized clearing will be required for additional categories of swaps on a phased-in basis based on requirements published by the Securities and Exchange Commission and Commodity Futures Trading Commission.

At the time the Fund enters into a centrally cleared swap, the Fund deposits and maintains as collateral an initial margin with the broker, as required by the clearinghouse on which the transaction is effected. Such amount is shown as cash collateral due from broker on the

abfunds.com AB MUNICIPAL INCOME SHARES    ^|    133

NOTES TO FINANCIAL STATEMENTS (continued)

statement of assets and liabilities. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. Risks may arise from the potential inability of a counterparty to meet the terms of the contract. The credit/counterparty risk for centrally cleared swaps is generally less than non-centrally cleared swaps, since the clearinghouse, which is the issuer or counterparty to each centrally cleared swap, has robust risk mitigation standards, including the requirement to provide initial and variation margin. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the time it was closed.

Interest Rate Swaps:

The Fund is subject to interest rate risk exposure in the normal course of pursuing its investment objectives. Because the Fund holds fixed rate bonds, the value of these bonds may decrease if interest rates rise. To help hedge against this risk and to maintain its ability to generate income at prevailing market rates, the Fund may enter into interest rate swaps. Interest rate swaps are agreements between two parties to exchange cash flows based on a notional amount. The Fund may elect to pay a fixed rate and receive a floating rate, or, receive a fixed rate and pay a floating rate on a notional amount.

In addition, the Fund may also enter into interest rate swap transactions to preserve a return or spread on a particular investment or portion of its portfolio, or protecting against an increase in the price of securities the Fund anticipates purchasing at a later date. Interest rate swaps involve the exchange by the Fund with another party of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments) computed based on a contractually-based principal (or “notional”) amount. Interest rate swaps are entered into on a net basis (i.e., the two payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the two payments).

During the six months ended October 31, 2023, the Fund held interest rate swaps for hedging purposes.

Inflation (CPI) Swaps:

Inflation swap agreements are contracts in which one party agrees to pay the cumulative percentage increase in a price index (the Consumer Price Index with respect to CPI swaps) over the term of the swap (with some lag on the inflation index), and the other pays a compounded fixed rate. Inflation swaps may be used to protect the net asset value, or NAV, of a Fund against an unexpected change in

134    ^|    AB MUNICIPAL INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

the rate of inflation measured by an inflation index since the value of these agreements is expected to increase if there are unexpected inflation increases.

During the six months ended October 31, 2023, the Fund held inflation (CPI) swaps for hedging purposes.

The Fund typically enters into International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreement”) with its OTC derivative contract counterparties in order to, among other things, reduce its credit risk to OTC counterparties. ISDA Master Agreements include provisions for general obligations, representations, collateral and events of default or termination. Under an ISDA Master Agreement, the Fund typically may offset with the OTC counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment (close-out netting) in the event of default or termination. In the event of a default by an OTC counterparty, the return of collateral with market value in excess of the Fund’s net liability, held by the defaulting party, may be delayed or denied.

The Fund’s ISDA Master Agreements may contain provisions for early termination of OTC derivative transactions in the event the net assets of the Fund decline below specific levels (“net asset contingent features”). If these levels are triggered, the Fund’s OTC counterparty has the right to terminate such transaction and require the Fund to pay or receive a settlement amount in connection with the terminated transaction. If OTC derivatives were held at period end, please refer to netting arrangements by the OTC counterparty table below for additional details.

During the six months ended October 31, 2023, the Fund had entered into the following derivatives:

	Asset Derivatives				Liability Derivatives
Derivative Type	Statement of Assets and Liabilities Location	Fair Value			Statement of Assets and Liabilities Location	Fair Value
Interest rate contracts	Receivable for variation margin on centrally cleared swaps	$	180,926,596	*	Payable for variation margin on centrally cleared swaps	$	150,389,351	*

NOTE E

Risks Involved in Investing in the Fund

Market Risk—The value of the Fund’s assets will fluctuate as the stock or bond market fluctuates. 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.

Credit Risk—An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security and any accrued interest. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.

Municipal Market Risk—This is the risk that special factors may adversely affect the value of municipal securities and have a significant effect on the yield or value of the Fund’s investments in municipal securities. These factors include economic conditions, political or legislative changes, public health crises, uncertainties related to the tax status of municipal securities, and the rights of investors in these securities. To the extent that the Fund invests more of its assets in a particular state’s municipal securities, the Fund may be vulnerable to events adversely affecting that state, including economic, political and regulatory occurrences, court decisions, terrorism, public health crises (including the occurrence of a contagious disease or illness) and catastrophic natural

abfunds.com AB MUNICIPAL INCOME SHARES    ^|    137

NOTES TO FINANCIAL STATEMENTS (continued)

disasters, such as hurricanes, fires or earthquakes. The Fund’s investments in certain municipal securities with principal and interest payments that are made from the revenues of a specific project or facility, and not general tax revenues, may have increased risks. Factors affecting the project or facility, such as local business or economic conditions, could have a significant effect on the project’s ability to make payments of principal and interest on these securities.

In addition, changes in tax rates or the treatment of income from certain types of municipal securities, among other things, could negatively affect the municipal securities markets.

Tax Risk—There is no guarantee that all of the Fund’s income will remain exempt from federal or state income taxes. From time to time, the U.S. Government and the U.S. Congress consider changes in federal tax law that could limit or eliminate the federal tax exemption for municipal bond income, which would in effect reduce the income received by shareholders from the Fund by increasing taxes on that income. In such event, the Fund’s net asset value, or NAV, could also decline as yields on municipal bonds, which are typically lower than those on taxable bonds, would be expected to increase to approximately the yield of comparable taxable bonds. Actions or anticipated actions affecting the tax exempt status of municipal bonds could also result in significant shareholder redemptions of Fund shares as investors anticipate adverse effects on the Fund or seek higher yields to offset the potential loss of the tax deduction. As a result, the Fund would be required to maintain higher levels of cash to meet the redemptions, which would negatively affect the Fund’s yield. The federal income tax treatment of payments in respect of certain derivative contracts is unclear.

Below Investment-Grade Securities Risk—Investments in fixed-income securities with lower ratings (commonly known as “junk bonds”) tend to have a higher probability that an issuer will default or fail to meet its payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity and negative perceptions of the junk bond market generally and may be more difficult to trade than other types of securities.

Interest-Rate Risk—Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of existing investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest-rate risk is generally greater for fixed-income securities with longer maturities or durations. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the recent end

NOTES TO FINANCIAL STATEMENTS (continued)

of a period of historically low rates and the effects of potential central bank monetary policy, and government fiscal policy, initiatives and market reactions to those initiatives.

Duration Risk—Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to the full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise.

Inflation Risk—This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Fund’s assets can decline as can the value of the Fund’s distributions. This risk is significantly greater for fixed-income securities with longer maturities.

Leverage Risk—When the Fund borrows money or otherwise leverages its investments, its performance may be volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s investments. The Fund may create leverage through the use of reverse repurchase arrangements, forward currency exchange contracts, forward commitments, dollar rolls or futures or by borrowing money. The use of other types of derivative instruments by the Fund, such as options and swaps, may also result in a form of leverage. Leverage may result in higher returns to the Fund than if the Fund were not leveraged, but may also adversely affect returns, particularly if the market is declining.

Illiquid Investments Risk—Illiquid investments risk exists when particular investments, such as lower-rated securities, are or become difficult to purchase or sell, possibly preventing the Fund from selling such investments at an advantageous price. The Fund is subject to illiquid investments risk because the market for municipal securities is generally smaller than many other markets. Derivatives and securities involving substantial market and credit risk tend to involve greater illiquid investments risk than most other types of investments.

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

NOTES TO FINANCIAL STATEMENTS (continued)

LIBOR Replacement Risk—The Fund may be exposed to debt securities, derivatives or other financial instruments that recently transitioned from the London Interbank Offered Rate, or “LIBOR,” as a “benchmark” or “reference rate” for various interest rate calculations. LIBOR’s administrator, ICE Benchmark Administration, ceased publishing most LIBOR settings (including some U.S. LIBOR settings) by the end of 2021 and the remaining (and most widely used) U.S. Dollar LIBOR settings after June 30, 2023. The United Kingdom Financial Conduct Authority, which regulates LIBOR, will permit the use of synthetic U.S. Dollar LIBOR rates for non-U.S. contracts through September 30, 2024, but any such rates would be considered non-representative of the underlying market. Since 2018 the Federal Reserve Bank of New York has published the Secured Overnight Financing Rate (referred to as SOFR), which is intended to replace U.S. Dollar LIBOR. SOFR is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities in the repurchase agreement (repo) market. There is no assurance that the composition or characteristics of SOFR or any such alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that the market for SOFR-linked financial instruments will have the same volume or liquidity as did the market for LIBOR-linked financial instruments prior to LIBOR’s discontinuance or unavailability. Neither the long-term effects of the LIBOR transition process nor its ultimate success can yet be known.

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, 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 F

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

140    ^|    AB MUNICIPAL INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

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 October 31, 2023.

NOTE G

Distributions to Shareholders

The tax character of distributions to be paid for the year ending April 30, 2024 will be determined at the end of the current fiscal year. The tax character of distributions paid during the fiscal years ended April 30, 2023 and April 30, 2022 were as follows:

	2023		2022
Distributions paid from:
Ordinary income	$	26,840,993	$	11,930,509
Total taxable distributions		26,840,993		11,930,509
Tax-exempt income		321,585,581		222,568,440
Total distributions paid	$	348,426,574	$	234,498,949

As of April 30, 2023, the components of accumulated earnings (deficit) on a tax basis were as follows:

Undistributed tax-exempt income	$	33,366,949
Accumulated capital and other losses		(26,050,107	)(a)
Unrealized appreciation (depreciation)		(459,469,225	)(b)
Total accumulated earnings (deficit)	$	(452,152,383	)(c)

(a) As of April 30, 2023, the Fund had a net capital loss carryforward of $26,050,107. During the fiscal year, the Fund utilized $22,650,158 of capital loss carry forwards to offset current year net realized gains.

(b) The differences between book-basis and tax-basis unrealized appreciation (depreciation) are attributable primarily to the tax treatment of tender option bonds, the tax treatment of swaps, and the tax deferral of losses on wash sales.

(c) The differences between book-basis and tax-basis components of accumulated earnings (deficit) are attributable primarily to the tax treatment of defaulted securities and dividends payable.

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 April 30, 2023, the Fund had a net short-term capital loss carryforward of $26,050,107, which may be carried forward for an indefinite period.

NOTE H

Floating Rate Notes Issued in Connection with Securities Held

The Fund may engage in tender option bond (“TOB”) transactions in which the Fund transfers a fixed rate bond (“Fixed Rate Bond”) into a Special

abfunds.com AB MUNICIPAL INCOME SHARES    ^|    141

NOTES TO FINANCIAL STATEMENTS (continued)

Purpose Vehicle (the “SPV”, which is generally organized as a trust). The Fund buys a residual interest in the assets and cash flows of the SPV, often referred to as an inverse floating rate obligation (“Inverse Floater”). The SPV also issues floating rate notes (“Floating Rate Notes”) which are sold to third parties. The Floating Rate Notes pay interest at rates that generally reset weekly and their holders have the option to tender their notes to a liquidity provider for redemption at par. The Inverse Floater held by the Fund gives the Fund the right (1) to cause the holders of the Floating Rate Notes to tender their notes at par, and (2) to have the trustee transfer the Fixed Rate Bond held by the SPV to the Fund, thereby collapsing the SPV. The SPV may also be collapsed in certain other circumstances. In accordance with U.S. GAAP requirements regarding accounting for transfers and servicing of financial assets and extinguishments of liabilities, the Fund accounts for the transaction described above as a secured borrowing by including the Fixed Rate Bond in its portfolio of investments and the Floating Rate Notes as a liability under the caption “Payable for floating rate notes issued” in its statement of assets and liabilities. Interest expense related to the Fund’s liability with respect to Floating Rate Notes is recorded as incurred. The interest expense is also included in the Fund’s expense ratio. At October 31, 2023, the amount of the Fund’s Floating Rate Notes outstanding was $580,230,000 and the related interest rate was 3.80% to 5.50%. For the six months ended October 31, 2023, the average amount of Floating Rate Notes outstanding and the daily weighted average interest rate were $513,071,630 and 3.68%, respectively.

The Fund may also purchase Inverse Floaters in the secondary market without first owning the underlying bond. Such an Inverse Floater is included in the Fund’s portfolio of investments but is not required to be treated as a secured borrowing and reflected in the Fund’s financial statements as a secured borrowing.

NOTE I

Recent Accounting Pronouncements

In December 2022, the Financial Accounting Standards Board issued an Accounting Standards Update, ASU 2022-06, “Reference Rate Reform (Topic 848) – Deferral of the Sunset Date of Topic 848”. ASU 2022-06 is an amendment to ASU 2020-04, which provided optional guidance to ease the potential accounting burden due to the discontinuation of the LIBOR and other interbank-offered based reference rates and which was effective as of March 12, 2020 through December 31, 2022. ASU 2022-06 extends the effective period through December 31, 2024. Management is currently evaluating the impact, if any, of applying ASU 2022-06.

Operation and Effectiveness of the Fund’s Liquidity Risk Management Program:

In October 2016, the Securities and Exchange Commission (“SEC”) adopted the open-end fund liquidity rule (the “Liquidity Rule”). In June 2018 the SEC adopted a requirement that funds disclose information about the operation and effectiveness of their Liquidity Risk Management Program (“LRMP”) in their reports to shareholders.

One of the requirements of the Liquidity Rule is for the Fund to designate an Administrator of the Fund’s Liquidity Risk Management Program. The Administrator of the Fund’s LRMP is AllianceBernstein L.P., the Fund’s investment adviser (the “Adviser”). The Adviser has delegated the responsibility to its Liquidity Risk Management Committee (the “Committee”).

Another requirement of the Liquidity Rule is for the Fund’s Board of Trustees (the “Fund Board”) to receive an annual written report from the Administrator of the LRMP, which addresses the operation of the Fund’s LRMP and assesses its adequacy and effectiveness. The Adviser provided the Fund Board with such annual report during the first quarter of 2023, which covered the period January 1, 2022 through December 31, 2022 (the “Program Reporting Period”).

The LRMP’s principal objectives include supporting the Fund’s compliance with limits on investments in illiquid assets and mitigating the risk that the Fund will be unable to meet its redemption obligations in a timely manner.

Pursuant to the LRMP, the Fund classifies the liquidity of its portfolio investments into one of the four categories defined by the SEC: Highly Liquid, Moderately Liquid, Less Liquid, and Illiquid. These classifications are reported to the SEC on Form N-PORT.

During the Program Reporting Period, the Committee reviewed whether the Fund’s strategy is appropriate for an open-end structure, incorporating any holdings of less liquid and illiquid assets. If the Fund participated in derivative transactions, the exposure from such transactions were considered in the LRMP.

The Committee also performed an analysis to determine whether the Fund is required to maintain a Highly Liquid Investment Minimum (“HLIM”). The Committee also incorporated the following information when determining the Fund’s reasonably anticipated trading size for purposes of liquidity monitoring: historical net redemption activity, a Fund’s concentration in an issuer, shareholder concentration, investment performance, total net assets, and distribution channels.

The Adviser informed the Fund Board that the Committee believes the Fund’s LRMP is adequately designed, has been implemented as intended,

146    ^|    AB MUNICIPAL INCOME SHARES abfunds.com

and has operated effectively since its inception. No material exceptions have been noted since the implementation of the LRMP. During the Program Reporting Period, liquidity in all markets was challenged due to rising rates and economic uncertainty. However, markets also remained orderly during the Program Reporting Period. There were no liquidity events that impacted the Fund or its ability to timely meet redemptions during the Program Reporting Period.

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

The disinterested trustees (the “directors”) of AB Corporate Shares (the “Company”) unanimously approved the continuance of the Company’s Advisory Agreement with the Adviser in respect of AB Municipal Income Shares (the “Fund”) at a meeting held in-person on August 1-2, 2023 (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 noted that the Fund is designed as a vehicle for the wrap fee account market (where investors pay fees to a wrap fee sponsor which pays investment fees and expenses from such fee). The directors also noted that no advisory fee is payable by the Fund, that the Advisory Agreement does not include the reimbursement provision for certain administrative expenses included in the advisory agreements of most of the open-end AB Funds, and that the Adviser is responsible for payment of the Fund’s ordinary expenses. The directors noted that the Company acknowledges in the Advisory Agreement that the Adviser and its affiliates expect to receive compensation from third parties in connection with services provided under the Advisory Agreement. The directors further noted that the Adviser receives payments from the wrap fee program sponsors (the “Sponsors”) that use the Fund as an investment vehicle for their clients.

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.

148    ^|    AB MUNICIPAL INCOME SHARES abfunds.com

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 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 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 2021 and 2022 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. 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.

abfunds.com AB MUNICIPAL INCOME SHARES    ^|    149

Fall-Out Benefits

The directors considered the other benefits to the Adviser and its affiliates from their relationships with the Fund and the underlying fund advised by the Adviser in which the Fund invests. The directors noted that the Adviser is compensated by the Sponsors. 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 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 the Fund’s performance against a broad-based securities market index, in each case for the 1-, 3-, 5- and 10-year periods ended May 31, 2023 and (in the case of comparisons with the broad-based securities market index) for the period from inception. The directors were cognizant that the Fund was neither designed nor offered as a standalone investment and was intended to serve solely as a component of certain separately managed accounts (“SMAs”). The Adviser had explained that this attribute made it difficult to select an appropriate benchmark for the Fund. At the directors’ request, the Adviser provided information showing the weighting of the Fund in a current SMA and the overall performance of the SMA versus its stated benchmark. Based on their review, the directors concluded that the Fund’s investment performance was acceptable.

Advisory Fees

The directors considered the advisory fee rate payable by the Fund to the Adviser (zero) and information provided 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 payable by other funds.

The directors noted the unusual arrangements in the Advisory Agreement providing for no advisory fee but were cognizant that the Adviser is indirectly compensated by the Sponsors for its services to the Fund. The directors reviewed the fee arrangements between the Adviser and each of the current Sponsors and noted that such fees were negotiated on an arm’s length basis and were within the range of fees paid by wrap fee sponsors to other advisers of similar funds. While the Adviser’s fee arrangements with the Sponsors vary, the directors acknowledged the

150    ^|    AB MUNICIPAL INCOME SHARES abfunds.com

Adviser’s view that a portion of such fees (less the expenses of the Fund paid by the Adviser) may reasonably be viewed as compensating the Adviser for advisory services it provides to the Fund (the “implied fee”) and that the Adviser believes that while the Sponsors pay the Adviser different fee rates, the rate of fee attributable to Fund management at the Fund level is the same for all Sponsors. The directors also considered the fee rate schedules used by other registered investment companies that invest in fixed income securities that are advised by the Adviser.

The Adviser informed the directors that there were no institutional products managed by the Adviser that utilize investment strategies similar to those of the Fund.

The directors did not consider comparative expense information for the Fund because the Fund does not bear ordinary expenses.

Economies of Scale

The directors did not consider the extent to which fee levels in the Advisory Agreement for the Fund reflect economies of scale because the Advisory Agreement does not provide for any compensation to be paid to the Adviser by the Fund and the Fund’s expense ratio is zero. They did note, however, that the fee payable to the Adviser by the current Sponsors declines at a breakpoint based on either individual account sizes or on total assets managed by the Adviser for the Sponsor.

SEMI-ANNUAL REPORT

December 11, 2023

This report provides management’s discussion of fund performance for AB Impact Municipal Income Shares for the semi-annual reporting period ended October 31, 2023. Please note, shares of this Fund are available only to separately managed accounts or participants in “wrap fee” programs or other investment programs approved by the Adviser.

The investment objective of the Fund is to earn the highest level of current income, exempt from federal taxation, that is available consistent with what the Adviser considers to be an appropriate level of risk.

NAV RETURNS AS OF OCTOBER 31, 2023 (unaudited)

	6 Months		12 Months
AB IMPACT MUNICIPAL INCOME SHARES		-6.48%		2.30%
Bloomberg Municipal Bond Index		-4.65%		2.64%

INVESTMENT RESULTS

The table above shows the Fund’s performance compared with its benchmark, the Bloomberg Municipal Bond Index, for the six- and 12-month periods ended October 31, 2023.

For the six-month period, the Fund underperformed the benchmark. Duration and yield-curve positioning detracted, relative to the benchmark. An overweight to local general obligation and tax-supported state lease contributed to performance. Security selection in public health care and public higher education detracted.

For the 12-month period, the Fund underperformed the benchmark. Duration and yield-curve positioning detracted, relative to the benchmark. Overall security selection contributed, due to overweights to the toll roads and tax-supported state lease sectors. Underweights to primary/secondary education and water & sewer detracted.

The Fund used derivatives for hedging purposes in the form of interest rate swaps, which added to absolute performance for both periods, as well as Consumer Price Index swaps, which had no material impact for either period.

MARKET REVIEW AND INVESTMENT STRATEGY

For the six-month period ending October 31, 2023, the yield on a 10-Year AAA municipal bond rose to 3.61% from 2.36% and the yield on the 10-Year US Treasury rose to 4.91% from 3.60%. After-tax spreads

compressed over the period, which indicated the municipals became more expensive relative to Treasuries. However, worries that the US Federal Reserve would continue its policy tightening stance longer than anticipated caused a sell-off during the period and was a headwind to performance.

The underlying goals of the Fund are to make environmentally, socially and financially productive investments in historically marginalized and underserved communities to reduce gaps that exist in such areas as academic achievement, economic development or the provision of health care. Essentially, the Fund’s Senior Investment Management Team is looking to create a better tomorrow. Inherent in these goals is to make investments toward improving the quality of life for all by enhancing and promoting civic engagement, an informed citizenry, culture, and the physical and natural sciences.

The Fund may purchase municipal securities that are insured under policies issued by certain insurance companies. Historically, insured municipal securities typically received a higher credit rating, which meant that the issuer of the securities paid a lower interest rate. As a result of declines in the credit quality and associated downgrades of most bond insurers, insurance has less value than it did in the past. In purchasing such insured securities, the Adviser evaluates the risk and return of municipal securities through its own research. If an insurance company’s rating is downgraded or the company becomes insolvent, the prices of municipal securities insured by the insurance company may decline. As of October 31, 2023, the Fund’s percentages of investments in municipal bonds that are insured and in insured municipal bonds that have been pre-refunded or escrowed to maturity were 11.68% and 0.00%, respectively.

INVESTMENT POLICIES

The Fund pursues its objective by investing principally in high-yielding municipal securities of any credit quality that (i) score highly on the Adviser’s environmental, social and corporate governance (“ESG”) criteria and (ii) are deemed by the Adviser to have an environmental or social impact in underserved or low socio-economic communities. As a matter of fundamental policy, the Fund invests, under normal circumstances, at least 80% of its net assets in municipal securities that pay interest that is exempt from federal income tax. These securities may pay interest that is subject to the federal alternative minimum tax for certain taxpayers.

The Adviser evaluates each security in which the Fund invests using both a traditional municipal bond credit analysis and a consideration of the security’s overall ESG score under the Adviser’s ESG evaluation criteria. Under this ESG evaluation, to arrive at an overall ESG score,

(continued on next page)

abfunds.com AB IMPACT MUNICIPAL INCOME SHARES    ^|    3

each security is scored on environmental, social and governance factors, and the scores are weighted based on the Adviser’s assessment of the relevance of each factor within a given sector (e.g., education, health care, renewable energy and mass transit). For example, social factors are weighted more heavily in the overall ESG score for a security of an issuer in the education sector than they are for a security of an issuer in the mass transit sector, where environmental factors predominate. The Adviser regularly reviews the overall ESG scores assigned to securities under consideration for purposes of determining the securities in which to invest for the Fund.

The Adviser’s ESG evaluation is conducted on an industry sector basis and includes the use of key performance indicators that vary in materiality by sector. The Adviser’s environmental evaluation covers issues such as clean and renewable energy, climate change and water conservation. The Adviser’s social evaluation covers issues such as economic impact, high quality safety-net health care and overall community health needs, and the reduction of achievement gaps between wealthy and poor school districts. The Adviser’s governance evaluation covers issues such as stewardship of debt and capital, board governance and transparency.

The Adviser also assesses a security’s risk and return characteristics as well as a security’s impact on the overall risk and return characteristics of the Fund. In making this assessment, the Adviser takes into account various factors including the credit quality, maturity, sensitivity to interest rates and the expected after-tax returns of the security under consideration and of the Fund’s other holdings.

The Fund may invest without limit in lower-rated securities (“junk bonds”), which may include securities having the lowest rating, and in unrated securities that, in the Adviser’s judgment, would be lower-rated securities if rated. The Fund may invest in fixed-income securities with any maturity or duration. The Fund will seek to increase income for shareholders by investing in longer-maturity bonds. Consistent with its objective of seeking a higher level of income, the Fund may experience greater volatility and a higher risk of loss of principal than other municipal funds.

The Fund may also invest in tender option bond transactions (“TOBs”); forward commitments; zero-coupon municipal securities and variable-, floating- and inverse-floating-rate municipal securities; certain types of mortgage-related securities; and derivatives, such as options, futures contracts, forwards and swaps.

(continued on next page)

The Fund may make short sales of securities or maintain a short position, and may use other investment techniques. The Fund may use leverage for investment purposes to increase income through the use of TOBs and derivative instruments, such as interest rate swaps.

DISCLOSURES AND RISKS

Benchmark Disclosure

The Bloomberg Municipal Bond Index is unmanaged and does not reflect fees and expenses associated with the active management of a fund. The Bloomberg Municipal Bond Index represents the performance of the long-term tax-exempt bond market consisting of investment-grade bonds. An investor cannot invest directly in an index, and its 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 assets will fluctuate as the stock or bond market fluctuates. 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.

ESG Risk: Applying ESG and sustainability criteria to the investment process may exclude securities of certain issuers for non-investment reasons and, therefore, the Fund may forgo some market opportunities available to funds that do not use ESG or sustainability criteria. Securities selected based on ESG factors may shift into and out of favor depending on market and economic conditions, and the Fund’s performance may at times be better or worse than the performance of funds that do not use ESG or sustainability criteria. Furthermore, ESG sustainability criteria are not uniformly defined, and the Fund’s ESG and sustainability criteria may differ from those used by other funds. In addition, in evaluating an investment, the Adviser is dependent upon information and data that may be incomplete, inaccurate or unavailable, which could adversely affect the analysis of the ESG and sustainability factors relevant to a particular investment.

Credit Risk: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security and any accrued interest. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.

Municipal Market Risk: This is the risk that special factors may adversely affect the value of municipal securities and have a significant effect on the

6    ^|    AB IMPACT MUNICIPAL INCOME SHARES abfunds.com

DISCLOSURES AND RISKS (continued)

yield or value of the Fund’s investments in municipal securities. These factors include economic conditions, political or legislative changes, public health crises, uncertainties related to the tax status of municipal securities, and the rights of investors in these securities. To the extent that the Fund invests more of its assets in a particular state’s municipal securities, the Fund may be vulnerable to events adversely affecting that state, including economic, political and regulatory occurrences, court decisions, terrorism, public health crises (including the occurrence of a contagious disease or illness) and catastrophic natural disasters, such as hurricanes, fires or earthquakes. The Fund’s investments in certain municipal securities with principal and interest payments that are made from the revenues of a specific project or facility, and not general tax revenues, may have increased risks. Factors affecting the project or facility, such as local business or economic conditions, could have a significant effect on the project’s ability to make payments of principal and interest on these securities.

In addition, changes in tax rates or the treatment of income from certain types of municipal securities, among other things, could negatively affect the municipal securities markets.

Tax Risk: There is no guarantee that all of the Fund’s income will remain exempt from federal or state income taxes. From time to time, the US government and the US Congress consider changes in federal tax law that could limit or eliminate the federal tax exemption for municipal bond income, which would in effect reduce the income received by shareholders from the Fund by increasing taxes on that income. In such event, the Fund’s net asset value (“NAV”) could also decline as yields on municipal bonds, which are typically lower than those on taxable bonds, would be expected to increase to approximately the yield of comparable taxable bonds. Actions or anticipated actions affecting the tax-exempt status of municipal bonds could also result in significant shareholder redemptions of Fund shares as investors anticipate adverse effects on the Fund or seek higher yields to offset the potential loss of the tax deduction. As a result, the Fund would be required to maintain higher levels of cash to meet the redemptions, which would negatively affect the Fund’s yield. The federal income tax treatment of payments in respect of certain derivative contracts is unclear.

Below Investment-Grade Securities Risk: Investments in fixed-income securities with lower ratings (commonly known as “junk bonds”) tend to have a higher probability that an issuer will default or fail to meet its payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest-rate sensitivity, negative perceptions of the junk bond market generally and may be more difficult to trade than other types of securities.

abfunds.com AB IMPACT MUNICIPAL INCOME SHARES    ^|    7

DISCLOSURES AND RISKS (continued)

Interest-Rate Risk: Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of existing investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest-rate risk is generally greater for fixed-income securities with longer maturities or durations. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the end of a recent period of historically low rates and the effect of potential central bank monetary policy, and government fiscal policy, initiatives and resulting market reactions to those initiatives.

Duration Risk: Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise.

Inflation Risk: This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Fund’s assets can decline as can the value of the Fund’s distributions. This risk is significantly greater for fixed-income securities with longer maturities.

Leverage Risk: To the extent the Fund uses leveraging techniques, its NAV may be more volatile because leverage tends to exaggerate the effect of changes in interest rates and any increase or decrease in the value of the Fund’s investments.

Illiquid Investments Risk: Illiquid investments risk exists when particular investments, such as lower-rated securities, are or become difficult to purchase or sell, possibly preventing the Fund from selling such investments at an advantageous price. The Fund is subject to illiquid investments risk because the market for municipal securities is generally smaller than many other markets. Derivatives and securities involving substantial market and credit risk tend to involve greater illiquid investments risk than most other types of investments.

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

DISCLOSURES AND RISKS (continued)

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

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

EXPENSE EXAMPLE

(unaudited)

As a shareholder of the Fund, you may incur various ongoing non-operating and extraordinary costs. 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.

	Beginning Account Value May 1, 2023		Ending Account Value October 31, 2023		Expenses Paid During Period*		Annualized Expense Ratio*
Actual	$	1,000	$	935.20	$	– 0 –		0.00	%
Hypothetical**	$	1,000	$	1,025.14	$	– 0 –		0.00	%

* Expenses are equal to the Fund’s annualized expense ratio, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). The Fund’s operating expenses are borne by the Adviser or its affiliates.

** Assumes 5% annual return before expenses.

PORTFOLIO SUMMARY

October 31, 2023 (unaudited)

PORTFOLIO STATISTICS

Net Assets ($mil): $514.9

1 The Fund’s quality rating breakdown is expressed as a percentage of the Fund’s total investments in municipal securities and may vary over time. The Fund also enters into derivative transactions, which may be used for hedging or investment purposes (see “Portfolio of Investments” section of the report for additional details). The quality ratings are determined by using the S&P Global Ratings (“S&P”), Moody’s Investors Services, Inc. (“Moody’s”) and Fitch Ratings, Ltd. (“Fitch”). The Fund considers the credit ratings issued by S&P, Moody’s and Fitch and uses the highest rating issued by the agencies. These ratings are a measure of the quality and safety of a bond or portfolio, based on the issuer’s financial condition. AAA is the highest (best) and D is the lowest (worst). If applicable, the pre-refunded category includes bonds which are secured by U.S. Government securities and therefore are deemed high-quality investment-grade by the Adviser. If applicable, Not Applicable (N/A) includes non-creditworthy investments such as equities, currency contracts, futures and options. If applicable, the Not Rated category includes bonds that are not rated by a nationally recognized statistical rating organization. The Adviser evaluates the creditworthiness of non-rated securities based on a number of factors including, but not limited to, cash flows, enterprise value and economic environment.

NOTES TO FINANCIAL STATEMENTS

October 31, 2023 (unaudited)

NOTE A

Significant Accounting Policies

AB Corporate Shares (the “Trust”) is registered under the Investment Company Act of 1940 (the “1940 Act”), as an open-end, diversified management investment company. The Trust, which is a Massachusetts Business Trust, operates as a “series” company currently offering five separate portfolios: AB Corporate Income Shares, AB Municipal Income Shares, AB Taxable Multi-Sector Income Shares, AB Impact Municipal Income Shares and AB Tax-Aware Real Return Income Shares. Each portfolio is considered to be a separate entity for financial reporting and tax purposes. This report relates only to AB Impact Municipal Income Shares (the “Fund”).

Shares of the Fund are offered exclusively to holders of accounts established under wrap fee programs sponsored and maintained by certain registered investment advisers approved by AllianceBernstein L.P. (the “Adviser”). The Fund’s shares may be purchased at the relevant net asset value without a sales charge or other fee. 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 Trust’s Board of Trustees (the “Board”). Pursuant to these procedures, 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 sale on such day, the securities are valued at the last traded price from the previous day. Securities listed on more

abfunds.com AB IMPACT MUNICIPAL INCOME SHARES    ^|    33

NOTES TO FINANCIAL STATEMENTS (continued)

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

34    ^|    AB IMPACT MUNICIPAL INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

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)

The fair value of debt instruments, such as bonds, and over-the-counter derivatives is generally based on market price quotations, recently executed market transactions (where observable) or industry recognized modeling techniques and are generally classified as Level 2. Pricing vendor inputs to Level 2 valuations may include quoted prices for similar investments in active markets, interest rate curves, coupon rates, currency rates, yield curves, option adjusted spreads, default rates, credit spreads and other unique security features in order to estimate the relevant cash flows which are then discounted to calculate fair values. If these inputs are unobservable and significant to the fair value, these investments will be classified as Level 3.

Other fixed income investments, including non-U.S. government and corporate debt, are generally valued using quoted market prices, if available,

abfunds.com AB IMPACT MUNICIPAL INCOME SHARES    ^|    35

NOTES TO FINANCIAL STATEMENTS (continued)

which are typically impacted by current interest rates, maturity dates and any perceived credit risk of the issuer. Additionally, in the absence of quoted market prices, these inputs are used by pricing vendors to derive a valuation based upon industry or proprietary models which incorporate issuer specific data with relevant yield/spread comparisons with more widely quoted bonds with similar key characteristics. Those investments for which there are observable inputs are classified as Level 2. Where the inputs are not observable, the investments are classified as Level 3.

The following table summarizes the valuation of the Fund’s investments by the above fair value hierarchy levels as of October 31, 2023:

(a) Other financial instruments include reverse repurchase agreements and 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.

(b) Only variation margin receivable (payable) at period end is reported within the statement of assets and liabilities. This amount reflects cumulative unrealized appreciation (depreciation) on futures and centrally cleared swaps as reported in the portfolio of investments. Where applicable, centrally cleared swaps with upfront premiums are presented here at market value.

3. 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.

36    ^|    AB IMPACT MUNICIPAL INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

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.

4. 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 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.

5. 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 advisory agreement, the Fund pays no advisory fee to the Adviser and the Adviser reimburses or pays for the Fund’s operating expenses. The Fund is an integral part of separately managed accounts in wrap-fee programs and other investment programs. Typically, participants in these programs pay a fee to their investment adviser for all costs and expenses of the separately managed account, including costs and expenses associated with the Fund, and a fee is paid by their investment adviser to the Adviser. In certain cases, participants may have a direct relationship with the Adviser without the involvement of a third party investment adviser, in which case the participant would pay a fee directly to the Adviser. The Adviser serves as investment manager and adviser of the Fund and continuously furnishes an investment program for the Fund and manages, supervises and conducts the affairs of the Fund, subject to the supervisions of the Fund’s Board. The advisory agreement provides

NOTES TO FINANCIAL STATEMENTS (continued)

that the Adviser or an affiliate will furnish, or pay the expenses of the Fund for, office space, facilities and equipment, services of executive and other personnel of the Fund and certain administrative services.

The Fund has entered into a distribution agreement with AllianceBernstein Investments, Inc., the Fund’s principal underwriter (the “Underwriter”), to permit the Underwriter to distribute the Fund’s shares, which are sold at their net asset value without any sales charge. The Fund does not pay a fee for this service. The Underwriter is a wholly owned subsidiary of the Adviser.

AllianceBernstein Investor Services, Inc. (“ABIS”), a wholly-owned subsidiary of the Adviser, acts as the Fund’s registrar, transfer agent and dividend-disbursing agent. ABIS registers the transfer, issuance and redemption of Fund shares and disburses dividends and other distributions to Fund shareholders. The Fund does not pay a fee for this service.

The Fund may invest in AB Government Money Market Portfolio (the “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 Government Money Market Portfolio (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 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 Government Money Market Portfolio, the Adviser has contractually agreed to reimburse the Fund in an amount equal to the Fund’s pro rata share of the effective advisory fee of Government Money Market Portfolio, as borne indirectly by the Fund as an acquired fund fee and expense. For the six months ended October 31, 2023, such reimbursement amounted to $4,602.

A summary of the Fund’s transactions in AB mutual funds for the six months ended October 31, 2023 is as follows:

Fund	Market Value 4/30/23 (000)		Purchases at Cost (000)		Sales Proceeds (000)		Market Value 10/31/23 (000)		Dividend Income (000)

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 principal types of derivatives utilized by the Fund, as well as the methods in which they may be used are:

• Swaps

The Fund may enter into swaps to hedge its exposure to interest rates, credit risk, equity markets or currencies. A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. The payment flows are usually netted against each other, with the difference being paid by one party to the other. In addition, collateral may be pledged or received by the Fund in accordance with the terms of the respective swaps to provide value and recourse to the Fund or its counterparties in the event of default, bankruptcy or insolvency by one of the parties to the swap.

Risks may arise as a result of the failure of the counterparty to the swap to comply with the terms of the swap. The loss incurred by the failure of a counterparty is generally limited to the net interim payment to be received by the Fund, and/or the termination value at the end of the contract. Therefore, the Fund considers the creditworthiness of each counterparty to a swap in evaluating potential counterparty risk.

abfunds.com AB IMPACT MUNICIPAL INCOME SHARES    ^|    39

NOTES TO FINANCIAL STATEMENTS (continued)

This risk is mitigated by having a netting arrangement between the Fund and the counterparty and by the posting of collateral by the counterparty to the Fund to cover the Fund’s exposure to the counterparty. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying securities. The Fund accrues for the interim payments on swaps on a daily basis, with the net amount recorded within unrealized appreciation/depreciation of swaps on the statement of assets and liabilities, where applicable. Once the interim payments are settled in cash, the net amount is recorded as realized gain/(loss) on swaps on the statement of operations, in addition to any realized gain/(loss) recorded upon the termination of swaps. Upfront premiums paid or received for swaps are recognized as cost or proceeds on the statement of assets and liabilities and are amortized on a straight line basis over the life of the contract. Amortized upfront premiums are included in net realized gain/(loss) from swaps on the statement of operations. Fluctuations in the value of swaps are recorded as a component of net change in unrealized appreciation/depreciation of swaps on the statement of operations.

Certain standardized swaps, including certain interest rate swaps and credit default swaps, are (or soon will be) subject to mandatory central clearing. Cleared swaps are transacted through futures commission merchants (“FCMs”) that are members of central clearinghouses, with the clearinghouse serving as central counterparty, similar to transactions in futures contracts. Centralized clearing will be required for additional categories of swaps on a phased-in basis based on requirements published by the Securities and Exchange Commission and Commodity Futures Trading Commission.

At the time the Fund enters into a centrally cleared swap, the Fund deposits and maintains as collateral an initial margin with the broker, as required by the clearinghouse on which the transaction is effected. Such amount is shown as cash collateral due from broker on the statement of assets and liabilities. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. Risks may arise from the potential inability of a counterparty to meet the terms of the contract. The credit/counterparty risk for centrally cleared swaps is generally less than non-centrally cleared swaps, since the clearinghouse, which is the issuer or counterparty to each centrally cleared swap, has robust risk mitigation standards, including the requirement to provide initial and variation margin. When the contract is closed, the Fund records a

40    ^|    AB IMPACT MUNICIPAL INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

realized gain or loss equal to the difference between the value of the contract at the time it was opened and the time it was closed.

Interest Rate Swaps:

The Fund is subject to interest rate risk exposure in the normal course of pursuing its investment objectives. Because the Fund holds fixed rate bonds, the value of these bonds may decrease if interest rates rise. To help hedge against this risk and to maintain its ability to generate income at prevailing market rates, the Fund may enter into interest rate swaps. Interest rate swaps are agreements between two parties to exchange cash flows based on a notional amount. The Fund may elect to pay a fixed rate and receive a floating rate, or, receive a fixed rate and pay a floating rate on a notional amount.

In addition, the Fund may also enter into interest rate swap transactions to preserve a return or spread on a particular investment or portion of its portfolio, or protecting against an increase in the price of securities the Fund anticipates purchasing at a later date. Interest rate swaps involve the exchange by the Fund with another party of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments) computed based on a contractually-based principal (or “notional”) amount. Interest rate swaps are entered into on a net basis (i.e., the two payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the two payments).

During the six months ended October 31, 2023, the Fund held interest rate swaps for hedging purposes.

Inflation (CPI) Swaps:

Inflation swap agreements are contracts in which one party agrees to pay the cumulative percentage increase in a price index (the Consumer Price Index with respect to CPI swaps) over the term of the swap (with some lag on the inflation index), and the other pays a compounded fixed rate. Inflation swaps may be used to protect the net asset value, or NAV, of a Fund against an unexpected change in the rate of inflation measured by an inflation index since the value of these agreements is expected to increase if there are unexpected inflation increases.

During the six months ended October 31, 2023, the Fund held inflation (CPI) swaps for hedging purposes.

The Fund typically enters into International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreement”) with its OTC derivative contract counterparties in order to, among other things, reduce its credit risk to OTC counterparties. ISDA Master Agreements include

abfunds.com AB IMPACT MUNICIPAL INCOME SHARES    ^|    41

NOTES TO FINANCIAL STATEMENTS (continued)

provisions for general obligations, representations, collateral and events of default or termination. Under an ISDA Master Agreement, the Fund typically may offset with the OTC counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment (close-out netting) in the event of default or termination. In the event of a default by an OTC counterparty, the return of collateral with market value in excess of the Fund’s net liability, held by the defaulting party, may be delayed or denied.

The Fund’s ISDA Master Agreements may contain provisions for early termination of OTC derivative transactions in the event the net assets of the Fund decline below specific levels (“net asset contingent features”). If these levels are triggered, the Fund’s OTC counterparty has the right to terminate such transaction and require the Fund to pay or receive a settlement amount in connection with the terminated transaction. If OTC derivatives were held at period end, please refer to netting arrangements by the OTC counterparty table below for additional details.

During the six months ended October 31, 2023, the Fund had entered into the following derivatives:

	Asset Derivatives				Liability Derivatives
Derivative Type	Statement of Assets and Liabilities Location	Fair Value			Statement of Assets and Liabilities Location	Fair Value
Interest rate contracts	Receivable for variation margin on centrally cleared swaps	$	2,431,353	*	Payable for variation margin on centrally cleared swaps	$	3,834,334	*
Total		$	2,431,353			$	3,834,334

* Only variation margin receivable/payable at period end is reported within the statement of assets and liabilities. This amount reflects cumulative unrealized appreciation (depreciation) on futures and centrally cleared swaps as reported in the portfolio of investments.

Risks Involved in Investing in the Fund

Market Risk—The value of the Fund’s assets will fluctuate as the stock or bond market fluctuates. 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.

ESG Risk—Applying ESG and sustainability criteria to the investment process may exclude securities of certain issuers for non-investment reasons and, therefore, the Fund may forgo some market opportunities available to funds that do not use ESG or sustainability criteria. Securities selected based on ESG factors may shift into and out of favor depending on market and economic conditions, and the Fund’s performance may at times be better or worse than the performance of funds that do not use ESG or sustainability criteria. Furthermore, ESG and sustainability criteria are not uniformly defined, and the Fund’s ESG and sustainability criteria may differ from those used by other funds. In addition, in evaluating an investment, the Adviser is dependent upon information and data that may be incomplete, inaccurate or unavailable, which could adversely affect the analysis of the ESG and sustainability factors relevant to a particular investment.

abfunds.com AB IMPACT MUNICIPAL INCOME SHARES    ^|    43

NOTES TO FINANCIAL STATEMENTS (continued)

Credit Risk—An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security and any accrued interest. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.

Municipal Market Risk—This is the risk that special factors may adversely affect the value of municipal securities and have a significant effect on the yield or value of the Fund’s investments in municipal securities. These factors include economic conditions, political or legislative changes, public health crises, uncertainties related to the tax status of municipal securities, and the rights of investors in these securities. To the extent that the Fund invests more of its assets in a particular state’s municipal securities, the Fund may be vulnerable to events adversely affecting that state, including economic, political and regulatory occurrences, court decisions, terrorism, public health crises (including the occurrence of a contagious disease or illness) and catastrophic natural disasters, such as hurricanes, fires or earthquakes. The Fund’s investments in certain municipal securities with principal and interest payments that are made from the revenues of a specific project or facility, and not general tax revenues, may have increased risks. Factors affecting the project or facility, such as local business or economic conditions, could have a significant effect on the project’s ability to make payments of principal and interest on these securities.

In addition, changes in tax rates or the treatment of income from certain types of municipal securities, among other things, could negatively affect the municipal securities markets.

Tax Risk—There is no guarantee that all of the Fund’s income will remain exempt from federal or state income taxes. From time to time, the U.S. Government and the U.S. Congress consider changes in federal tax law that could limit or eliminate the federal tax exemption for municipal bond income, which would in effect reduce the income received by shareholders from the Fund by increasing taxes on that income. In such event, the Fund’s net asset value, or NAV, could also decline as yields on municipal bonds, which are typically lower than those on taxable bonds, would be expected to increase to approximately the yield of comparable taxable bonds. Actions or anticipated actions affecting the tax exempt status of municipal bonds could also result in significant shareholder redemptions of

44    ^|    AB IMPACT MUNICIPAL INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

Fund shares as investors anticipate adverse effects on the Fund or seek higher yields to offset the potential loss of the tax deduction. As a result, the Fund would be required to maintain higher levels of cash to meet the redemptions, which would negatively affect the Fund’s yield. The federal income tax treatment of payments in respect of certain derivative contracts is unclear.

Below Investment-Grade Securities Risk—Investments in fixed-income securities with lower ratings (commonly known as “junk bonds”) tend to have a higher probability that an issuer will default or fail to meet its payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity and negative perceptions of the junk bond market generally and may be more difficult to trade than other types of securities.

Interest-Rate Risk—Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of existing investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest-rate risk is generally greater for fixed-income securities with longer maturities or durations. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the recent end of a period of historically low rates and the effects of potential central bank monetary policy, and government fiscal policy initiatives and resulting market reactions to those initiatives.

Duration Risk—Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to the full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise.

Inflation Risk—This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Fund’s assets can decline, as can the value of the Fund’s distributions. This risk is significantly greater for fixed-income securities with longer maturities.

Leverage Risk—When the Fund borrows money or otherwise leverages its investments, its performance may be volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s investments. The Fund may create leverage through the use of reverse repurchase arrangements, forward currency exchange contracts, forward commitments, dollar rolls or futures or by borrowing money. The use of other types of derivative instruments by the Fund, such as options and swaps, may also result in a form of leverage. Leverage may result in

abfunds.com AB IMPACT MUNICIPAL INCOME SHARES    ^|    45

NOTES TO FINANCIAL STATEMENTS (continued)

higher returns to the Fund than if the Fund were not leveraged, but may also adversely affect returns, particularly if the market is declining.

Illiquid Investments Risk—Illiquid investments risk exists when particular investments, such as lower-rated securities, are or become difficult to purchase or sell, possibly preventing the Fund from selling such investments at an advantageous price. The Fund is subject to illiquid investments risk because the market for municipal securities is generally smaller than many other markets. Derivatives and securities involving substantial market and credit risk tend to involve greater illiquid investments risk than most other types of investments.

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

LIBOR Replacement Risk—The Fund may be exposed to debt securities, derivatives or other financial instruments that recently transitioned from the London Interbank Offered Rate, or “LIBOR,” as a “benchmark” or “reference rate” for various interest rate calculations. LIBOR’s administrator, ICE Benchmark Administration, ceased publishing most LIBOR settings (including some U.S. LIBOR settings) by the end of 2021 and the remaining (and most widely used) U.S. Dollar LIBOR settings after June 30, 2023. The United Kingdom Financial Conduct Authority, which regulates LIBOR, will permit the use of synthetic U.S. Dollar LIBOR rates for non-U.S. contracts through September 30, 2024, but any such rates would be considered non-representative of the underlying market. Since 2018 the Federal Reserve Bank of New York has published the Secured Overnight Financing Rate (referred to as SOFR), which is intended to replace U.S. Dollar LIBOR. SOFR is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities in the repurchase agreement (repo) market. There is no assurance that the composition or characteristics of SOFR or any such alternative reference rate will be similar to or produce the same value or economic equivalence as LIBOR or that the market for SOFR-linked financial instruments will have the same volume or liquidity as did the market for LIBOR-linked financial instruments prior to LIBOR’s discontinuance or unavailability. Neither the long-term effects of the LIBOR transition process nor its ultimate success can yet be known.

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, 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 F

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, if necessary, subject to certain restrictions in connection with abnormal redemption activity. Commitment fees related to the Facility are paid by the Adviser. The Fund did not utilize the Facility during the six months ended October 31, 2023.

(b) The difference between book-basis and tax-basis unrealized appreciation (depreciation) is attributable primarily to the tax treatment of swaps.

(c) The difference between book-basis and tax-basis components of accumulated earnings (deficit) is attributable primarily to dividends payable.

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 April 30, 2023, the Fund had a net short-term capital loss carryforward of $4,437,809, which may be carried forward for an indefinite period.

Operation and Effectiveness of the Fund’s Liquidity Risk Management Program:

In October 2016, the Securities and Exchange Commission (“SEC”) adopted the open-end fund liquidity rule (the “Liquidity Rule”). In June 2018 the SEC adopted a requirement that funds disclose information about the operation and effectiveness of their Liquidity Risk Management Program (“LRMP”) in their reports to shareholders.

One of the requirements of the Liquidity Rule is for the Fund to designate an Administrator of the Fund’s Liquidity Risk Management Program. The Administrator of the Fund’s LRMP is AllianceBernstein L.P., the Fund’s investment adviser (the “Adviser”). The Adviser has delegated the responsibility to its Liquidity Risk Management Committee (the “Committee”).

Another requirement of the Liquidity Rule is for the Fund’s Board of Trustees (the “Fund Board”) to receive an annual written report from the Administrator of the LRMP, which addresses the operation of the Fund’s LRMP and assesses its adequacy and effectiveness. The Adviser provided the Fund Board with such annual report during the first quarter of 2023, which covered the period January 1, 2022 through December 31, 2022 (the “Program Reporting Period”).

The LRMP’s principal objectives include supporting the Fund’s compliance with limits on investments in illiquid assets and mitigating the risk that the Fund will be unable to meet its redemption obligations in a timely manner.

Pursuant to the LRMP, the Fund classifies the liquidity of its portfolio investments into one of the four categories defined by the SEC: Highly Liquid, Moderately Liquid, Less Liquid, and Illiquid. These classifications are reported to the SEC on Form N-PORT.

During the Program Reporting Period, the Committee reviewed whether the Fund’s strategy is appropriate for an open-end structure, incorporating any holdings of less liquid and illiquid assets. If the Fund participated in derivative transactions, the exposure from such transactions were considered in the LRMP.

The Committee also performed an analysis to determine whether the Fund is required to maintain a Highly Liquid Investment Minimum (“HLIM”). The Committee also incorporated the following information when determining the Fund’s reasonably anticipated trading size for purposes of liquidity monitoring: historical net redemption activity, a Fund’s concentration in an issuer, shareholder concentration, investment performance, total net assets, and distribution channels.

The Adviser informed the Fund Board that the Committee believes the Fund’s LRMP is adequately designed, has been implemented as intended,

abfunds.com AB IMPACT MUNICIPAL INCOME SHARES    ^|    51

and has operated effectively since its inception. No material exceptions have been noted since the implementation of the LRMP. During the Program Reporting Period, liquidity in all markets was challenged due to rising rates and economic uncertainty. However, markets also remained orderly during the Program Reporting Period. There were no liquidity events that impacted the Fund or its ability to timely meet redemptions during the Program Reporting Period.

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

The disinterested trustees (the “directors”) of AB Corporate Shares (the “Company”) unanimously approved the continuance of the Company’s Advisory Agreement with the Adviser in respect of AB Impact Municipal Income Shares (the “Fund”) at a meeting held in-person on August 1-2, 2023 (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 noted that the Fund is designed as a vehicle for the wrap fee account market (where investors pay fees to a wrap fee sponsor which pays investment fees and expenses from such fee). The directors also noted that no advisory fee is payable by the Fund, that the Advisory Agreement does not include the reimbursement provision for certain administrative expenses included in the advisory agreements of most of the open-end AB Funds, and that the Adviser is responsible for payment of the Fund’s ordinary expenses. The directors noted that the Company acknowledges in the Advisory Agreement that the Adviser and its affiliates expect to receive compensation from third parties in connection with services provided under the Advisory Agreement. The directors further noted that the Adviser receives payments from the wrap fee program sponsors (the “Sponsors”) that use the Fund as an investment vehicle for their clients.

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.

abfunds.com AB IMPACT MUNICIPAL INCOME SHARES    ^|    53

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 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 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 2020 and 2021 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. 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.

54    ^|    AB IMPACT MUNICIPAL INCOME SHARES abfunds.com

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. The directors noted that the Adviser is compensated by the Sponsors. 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 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 the Fund’s performance against a broad-based securities market index, in each case for the 1-, 3- and 5-year periods ended May 31, 2023 and (in the case of comparisons with the broad-based securities market index) for the period from inception. The directors were cognizant that the Fund was neither designed nor offered as a standalone investment and was intended to serve solely as a component of certain separately managed accounts (“SMAs”). The Adviser had explained that this attribute made it difficult to select an appropriate benchmark for the Fund. At the directors’ request, the Adviser provided information showing the weighting of the Fund in a current SMA and the overall performance of the SMA versus its stated benchmark. Based on their review, the directors concluded that the Fund’s investment performance was acceptable.

Advisory Fees

The directors considered the advisory fee rate payable by the Fund to the Adviser (zero) and information provided 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 payable by other funds.

The directors noted the unusual arrangements in the Advisory Agreement providing for no advisory fee but were cognizant that the Adviser is indirectly compensated by the Sponsors for its services to the Fund. The directors reviewed the fee arrangements between the Adviser and each of the current Sponsors and noted that such fees were negotiated on an arm’s length basis and were within the range of fees paid by wrap fee sponsors to other advisers of similar funds. While the Adviser’s fee arrangements with the Sponsors vary, the directors acknowledged the Adviser’s view that a portion of such fees (less the expenses of the Fund

abfunds.com AB IMPACT MUNICIPAL INCOME SHARES    ^|    55

paid by the Adviser) may reasonably be viewed as compensating the Adviser for advisory services it provides to the Fund (the “implied fee”) and that the Adviser believes that while the Sponsors pay the Adviser different fee rates, the rate of fee attributable to Fund management at the Fund level is the same for all Sponsors. The directors also considered the fee rate schedules used by other registered investment companies that invest in fixed income securities that are advised by the Adviser.

The Adviser informed the directors that there were no institutional products managed by the Adviser that utilize investment strategies similar to those of the Fund.

The directors did not consider comparative expense information for the Fund because the Fund does not bear ordinary expenses.

Economies of Scale

The directors did not consider the extent to which fee levels in the Advisory Agreement for the Fund reflect economies of scale because the Advisory Agreement does not provide for any compensation to be paid to the Adviser by the Fund and the Fund’s expense ratio is zero. They did note, however, that the fee payable to the Adviser by the current Sponsors declines at a breakpoint based on either individual account sizes or on total assets managed by the Adviser for the Sponsor.

SEMI-ANNUAL REPORT

December 20, 2023

This report provides management’s discussion of fund performance for AB Tax-Aware Real Return Income Shares for the semi-annual reporting period ended October 31, 2023. Please note, shares of this Fund are available only to separately managed accounts or participants in “wrap fee” programs or other investment programs approved by the Adviser.

The investment objective of the Fund is to maximize real after-tax return for investors subject to federal income taxation.

NAV RETURNS AS OF OCTOBER 31, 2023 (unaudited)

	6 Months		12 Months
AB TAX-AWARE REAL RETURN INCOME SHARES		-1.24%		2.42%
Bloomberg 1-10 Year TIPS Index		-2.72%		0.88%

INVESTMENT RESULTS

The table above shows the Fund’s performance compared with its benchmark, the Bloomberg 1-10 Year Treasury Inflation Protected Securities (“TIPS”) Index, for the six- and 12-month periods ended October 31, 2023.

For the six-month period, the Fund outperformed the benchmark. An allocation to interest rate swaps and 1-10 Year TIPS contributed to performance, relative to the benchmark, while Consumer Price Index (“CPI”) swaps detracted. Sector and security selection within the Fund’s municipal portfolio were both positive contributors over the period.

For the 12-month period, the Fund outperformed the benchmark. An allocation to 1-10 Year TIPS and interest rate swaps contributed to overall performance, while yield-curve positioning and an allocation to CPI swaps detracted. Sector and security selection within the Fund’s municipal portfolio were both positive contributors over the period.

The Fund used derivatives in form of interest rate swaps and total return swaps for hedging purposes, which had no material impact over both periods. CPI swaps were for hedging purposes, which had no material impact over the six-month period and detracted over the 12-month period.

MARKET REVIEW AND INVESTMENT STRATEGY

For the six-month period ending October 31, 2023, the yield on a 10-Year AAA municipal bond rose to 3.61% from 2.36% and the yield on the 10-Year US Treasury rose to 4.91% from 3.60%. After-tax spreads compressed over the period, which indicated the municipals became more expensive relative to Treasuries. However, worries that the US Federal

2    ^|    AB TAX-AWARE REAL RETURN INCOME SHARES abfunds.com

Reserve would continue its policy tightening stance longer than anticipated caused a sell-off during the period and was a headwind to performance.

The Fund’s Senior Investment Management Team (the “Team”) continues to focus on after-tax return by investing in municipal bonds that generate income exempt from federal income taxes. In seeking to manage volatility and interest-rate risk, the Team focuses on intermediate-term bonds and seeks to provide inflation protection by entering inflation swap agreements or investing in other inflation-protected instruments.

INVESTMENT POLICIES

The Fund seeks real after-tax return for investors who are subject to federal income taxes. Real return is the rate of return after adjusting for inflation. The Fund pursues its objective by investing primarily in municipal securities that pay interest exempt from federal taxation and by using inflation protection derivatives instruments. Municipal securities may pay interest that is subject to the federal alternative minimum tax for certain taxpayers.

The Fund may invest in fixed-income securities with any maturity or duration. The Fund may also invest without limit in fixed-income securities that are rated below investment grade (commonly known as “junk bonds”).

The Adviser selects securities for purchase or sale based on its assessment of the securities’ risk and return characteristics as well as the securities’ impact on the overall risk and return characteristics of the Fund. In making this assessment, the Adviser takes into account various factors, including the credit quality and sensitivity to interest rates of the securities under consideration and of the Fund’s other holdings.

The Fund may make significant use of derivatives, including swaps, futures, options and forwards. To provide inflation protection, the Fund will enter into various kinds of inflation swap agreements. The Fund may use other inflation-protected instruments. Payments to the Fund pursuant to swaps will result in taxable income, either ordinary income or capital gains, rather than income exempt from federal taxation. The Fund may at times seek a substantial amount of inflation protection and, consequently, may generate substantial taxable income. It is expected that the Fund’s primary use of derivatives will be for the purposes of inflation protection.

The Fund may also invest in forward commitments; zero-coupon municipal securities and variable-, floating- and inverse-floating-rate municipal securities; and certain types of mortgage-related securities.

(continued on next page)

abfunds.com AB TAX-AWARE REAL RETURN INCOME SHARES    ^|    3

The Fund may utilize leverage for investment purposes through the use of tender option bond transactions (“TOBs”). The Adviser will consider the impact of TOBs, swaps and other derivatives in making its assessments of the Fund’s risks. The resulting exposures to markets, sectors, issuers or specific securities will be continuously monitored by the Adviser.

DISCLOSURES AND RISKS

Benchmark Disclosure

The Bloomberg 1-10 Year TIPS Index is unmanaged and does not reflect fees and expenses associated with the active management of a fund. The Bloomberg 1-10 Year TIPS Index represents the performance of US Treasury inflation-indexed securities with maturities between one and 10 years. An investor cannot invest directly in an index, and its 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 assets will fluctuate as the stock or bond market fluctuates. 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.

Credit Risk: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security and any accrued interest. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.

Interest-Rate Risk: Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of existing investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest-rate risk is generally greater for fixed-income securities with longer maturities or durations. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the end of a recent period of historically low rates and the effect of potential central bank monetary policy, and government fiscal policy, initiatives and resulting market reactions to those initiatives.

Below Investment-Grade Securities Risk: Investments in fixed-income securities with lower ratings (commonly known as “junk bonds”) tend to have a higher probability that an issuer will default or fail to meet its payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments and negative

abfunds.com AB TAX-AWARE REAL RETURN INCOME SHARES    ^|    5

DISCLOSURES AND RISKS (continued)

perceptions of the junk bond market generally and may be more difficult to trade than other types of securities.

Duration Risk: Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. A short position in a derivative instrument involves the risk of a theoretically unlimited increase in the value of the underlying asset, which could cause the Fund to suffer a potentially unlimited loss. The duration of a fixed-income security may be shorter than or equal to full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise.

Municipal Market Risk: This is the risk that special factors may adversely affect the value of municipal securities and have a significant effect on the yield or value of the Fund’s investments in municipal securities. These factors include economic conditions, political or legislative changes, public health crises, uncertainties related to the tax status of municipal securities, and the rights of investors in these securities. To the extent that the Fund invests more of its assets in a particular state’s municipal securities, the Fund may be vulnerable to events adversely affecting that state, including economic, political and regulatory occurrences, court decisions, terrorism, public health crises (including the occurrence of a contagious disease or illness) and catastrophic natural disasters, such as hurricanes, fires or earthquakes. The Fund’s investments in certain municipal securities with principal and interest payments that are made from the revenues of a specific project or facility, and not general tax revenues, may have increased risks. Factors affecting the project or facility, such as local business or economic conditions, could have a significant effect on the project’s ability to make payments of principal and interest on these securities.

In addition, changes in tax rates or the treatment of income from certain types of municipal securities, among other things, could negatively affect the municipal securities markets.

Inflation Risk: This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Fund’s assets can decline as can the value of the Fund’s distributions. This risk is significantly greater for fixed-income securities with longer maturities.

Derivatives Risk: Derivatives may be difficult to price or unwind and leveraged so that small changes may produce disproportionate losses for the Fund. A short position in a derivative instrument involves the risk of a theoretically unlimited increase in the value of the underlying asset, which could cause the Fund to suffer a potentially unlimited loss. Derivatives, especially over-the-counter derivatives, are also subject to counterparty

6    ^|    AB TAX-AWARE REAL RETURN INCOME SHARES abfunds.com

DISCLOSURES AND RISKS (continued)

risk, which is the risk that the counterparty (the party on the other side of the transaction) on a derivative transaction will be unable or unwilling to honor its contractual obligations to the Fund.

Leverage Risk: To the extent the Fund uses leveraging techniques, such as TOBs, its net asset value (“NAV”) may be more volatile because leverage tends to exaggerate the effect of changes in interest rates and any increase or decrease in the value of the Fund’s investments.

Illiquid Investments Risk: Illiquid investments risk exists when particular investments, such as lower-rated securities, are or become difficult to purchase or sell, possibly preventing the Fund from selling such investments at an advantageous price. The Fund is subject to illiquid investments risk because the market for municipal securities is generally smaller than many other markets. Derivatives and securities involving substantial market and credit risk tend to involve greater illiquid investments risk than most other types of 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, 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.

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

EXPENSE EXAMPLE

(unaudited)

As a shareholder of the Fund, you may incur various ongoing non-operating and extraordinary costs. 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.

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.

Hypothetical**	$	1,000	$	1,025.14	$	– 0	–		0.00	%

* Expenses are equal to the Fund’s annualized expense ratio, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). The Fund’s operating expenses are borne by the Adviser or its affiliates.

** Assumes 5% annual return before expenses.

PORTFOLIO SUMMARY

PORTFOLIO STATISTICS

Net Assets ($mil): $7.8

1 The Fund’s quality rating breakdown is expressed as a percentage of the Fund’s total investments in municipal securities and may vary over time. The Fund also enters into derivative transactions, which may be used for hedging or investment purposes (see “Portfolio of Investments” section of the report for additional details). The quality ratings are determined by using the S&P Global Ratings (“S&P”), Moody’s Investors Services, Inc. (“Moody’s”) and Fitch Ratings, Ltd. (“Fitch”). The Fund considers the credit ratings issued by S&P, Moody’s and Fitch and uses the highest rating issued by the agencies. These ratings are a measure of the quality and safety of a bond or portfolio, based on the issuer’s financial condition. AAA is the highest (best) and D is the lowest (worst). If applicable, the pre-refunded category includes bonds which are secured by U.S. Government securities and therefore are deemed high-quality investment-grade by the Adviser. If applicable, Not Applicable (N/A) includes non-creditworthy investments, such as equities, currency contracts, futures and options. If applicable, the Not Rated category includes bonds that are not rated by a nationally recognized statistical rating organization. The Adviser evaluates the creditworthiness of non-rated securities based on a number of factors including, but not limited to, cash flows, enterprise value and economic environment.

NOTES TO FINANCIAL STATEMENTS

October 31, 2023 (unaudited)

NOTE A

Significant Accounting Policies

AB Corporate Shares (the “Trust”) is registered under the Investment Company Act of 1940 (the “1940 Act”), as an open-end, diversified management investment company. The Trust, which is a Massachusetts Business Trust, operates as a “series” company currently offering five separate portfolios: AB Corporate Income Shares, AB Municipal Income Shares, AB Taxable Multi-Sector Income Shares, AB Impact Municipal Income Shares and AB Tax-Aware Real Return Income Shares. Each portfolio is considered to be a separate entity for financial reporting and tax purposes. This report relates only to AB Tax-Aware Real Return Income Shares (the “Fund”).

Shares of the Fund are offered exclusively to holders of accounts established under wrap-fee programs sponsored and maintained by certain registered investment advisers approved by AllianceBernstein L.P. (the “Adviser”). The Fund’s shares may be purchased at the relevant net asset value without a sales charge or other fee. 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 Trust’s Board of Trustees (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 sale on such day, the securities are valued at the last traded price from the previous day. Securities listed on more

abfunds.com AB TAX-AWARE REAL RETURN INCOME SHARES    ^|    21

NOTES TO FINANCIAL STATEMENTS (continued)

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

22    ^|    AB TAX-AWARE REAL RETURN INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

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)

The fair value of debt instruments, such as bonds, and over-the-counter derivatives is generally based on market price quotations, recently executed market transactions (where observable) or industry recognized modeling techniques and are generally classified as Level 2. Pricing vendor inputs to Level 2 valuations may include quoted prices for similar investments in active markets, interest rate curves, coupon rates, currency rates, yield curves, option adjusted spreads, default rates, credit spreads and other unique security features in order to estimate the relevant cash flows which are then discounted to calculate fair values. If these inputs are unobservable and significant to the fair value, these investments will be classified as Level 3.

Other fixed income investments, including non-U.S. government and corporate debt, are generally valued using quoted market prices, if available, which are typically impacted by current interest rates, maturity dates and

abfunds.com AB TAX-AWARE REAL RETURN INCOME SHARES    ^|    23

NOTES TO FINANCIAL STATEMENTS (continued)

any perceived credit risk of the issuer. Additionally, in the absence of quoted market prices, these inputs are used by pricing vendors to derive a valuation based upon industry or proprietary models which incorporate issuer specific data with relevant yield/spread comparisons with more widely quoted bonds with similar key characteristics. Those investments for which there are observable inputs are classified as Level 2. Where the inputs are not observable, the investments are classified as Level 3.

The following table summarizes the valuation of the Fund’s investments by the above fair value hierarchy levels as of October 31, 2023:

(a) Other financial instruments include reverse repurchase agreements and 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.

(b) Only variation margin receivable (payable) at period end is reported within the statement of assets and liabilities. This amount reflects cumulative unrealized appreciation (depreciation) on futures and centrally cleared swaps as reported in the portfolio of investments. Where applicable, centrally cleared swaps with upfront premiums are presented here at market value.

3. 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.

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 tax year) and has concluded that no provision for income tax is required in the Fund’s financial statements.

4. 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 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.

5. 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.

NOTE B

Advisory Fee and Other Transactions with Affiliates

Under the terms of the Advisory Agreement, the Fund pays no advisory fee to the Adviser and the Adviser reimburses or pays for the Fund’s operating expenses. The Fund is an integral part of separately managed accounts in wrap-fee programs and other investment programs. Typically, participants in these programs pay a fee to their investment adviser for all costs and expenses of the separately managed account, including costs and expenses associated with the Fund, and a fee is paid by their investment adviser to the Adviser. In certain cases, participants may have a direct relationship with the Adviser without the involvement of a third party investment adviser, in which case the participant would pay a fee directly to the Adviser. The Adviser serves as investment manager and adviser of the Fund and continuously furnishes an investment program for the Fund and manages, supervises and conducts the affairs of the Fund, subject to the supervisions of the Fund’s Board. The Advisory Agreement provides that the Adviser or an affiliate will furnish, or pay the expenses of the Fund for, office space, facilities and equipment, services of executive and other personnel of the Fund and certain administrative services.

The Fund has entered into a distribution agreement with AllianceBernstein Investments, Inc., the Fund’s principal underwriter (the “Underwriter”), to permit the Underwriter to distribute the Fund’s shares, which are sold at

abfunds.com AB TAX-AWARE REAL RETURN INCOME SHARES    ^|    25

NOTES TO FINANCIAL STATEMENTS (continued)

their net asset value without any sales charge. The Fund does not pay a fee for this service. The Underwriter is a wholly owned subsidiary of the Adviser.

AllianceBernstein Investor Services, Inc. (“ABIS”), a wholly-owned subsidiary of the Adviser, acts as the Fund’s registrar, transfer agent and dividend-disbursing agent. ABIS registers the transfer, issuance and redemption of Fund shares and disburses dividends and other distributions to Fund shareholders. The Fund does not pay a fee for this service.

The Fund may invest in AB Government Money Market Portfolio (the “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 Government Money Market Portfolio (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 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 Government Money Market Portfolio, the Adviser has contractually agreed to reimburse its advisory fee from the Fund in an amount equal to the Fund’s pro rata share of the effective advisory fee of Government Money Market Portfolio, as borne indirectly by the Fund as an acquired fund fee and expense. For the six months ended October 31, 2023, such reimbursement amounted to $343.

A summary of the Fund’s transactions in AB mutual funds for the six months ended October 31, 2023 is as follows:

Fund	Market Value 4/30/23 (000)		Purchases at Cost (000)		Sales Proceeds (000)		Market Value 10/31/23 (000)		Dividend Income (000)

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 principal types of derivatives utilized by the Fund, as well as the methods in which they may be used are:

• Swaps

The Fund may enter into swaps to hedge its exposure to interest rates, credit risk, equity markets or currencies. A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. The payment flows are usually netted against each other, with the difference being paid by one party to the other. In addition, collateral may be pledged or received by the Fund in accordance with the terms of the respective swaps to provide value and recourse to the Fund or its counterparties in the event of default, bankruptcy or insolvency by one of the parties to the swap.

Risks may arise as a result of the failure of the counterparty to the swap to comply with the terms of the swap. The loss incurred by the failure of a counterparty is generally limited to the net interim payment to be received by the Fund, and/or the termination value at the end of the contract. Therefore, the Fund considers the creditworthiness of each counterparty to a swap in evaluating potential counterparty risk. This risk is mitigated by having a netting arrangement between the Fund and the counterparty and by the posting of collateral by the counterparty to the Fund to cover the Fund’s exposure to the counterparty. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying securities. The Fund accrues for the interim payments on swaps on a daily basis, with the net amount recorded within unrealized appreciation/depreciation of swaps on the statement of assets and liabilities, where applicable. Once the interim payments are settled in cash, the net amount is recorded as realized gain/(loss) on swaps on the statement

abfunds.com AB TAX-AWARE REAL RETURN INCOME SHARES    ^|    27

NOTES TO FINANCIAL STATEMENTS (continued)

of operations, in addition to any realized gain/(loss) recorded upon the termination of swaps. Upfront premiums paid or received for swaps are recognized as cost or proceeds on the statement of assets and liabilities and are amortized on a straight line basis over the life of the contract. Amortized upfront premiums are included in net realized gain/(loss) from swaps on the statement of operations. Fluctuations in the value of swaps are recorded as a component of net change in unrealized appreciation/depreciation of swaps on the statement of operations.

Certain standardized swaps, including certain interest rate swaps and credit default swaps, are (or soon will be) subject to mandatory central clearing. Cleared swaps are transacted through futures commission merchants (“FCMs”) that are members of central clearinghouses, with the clearinghouse serving as central counterparty, similar to transactions in futures contracts. Centralized clearing will be required for additional categories of swaps on a phased-in basis based on requirements published by the Securities and Exchange Commission and Commodity Futures Trading Commission.

At the time the Fund enters into a centrally cleared swap, the Fund deposits and maintains as collateral an initial margin with the broker, as required by the clearinghouse on which the transaction is effected. Such amount is shown as cash collateral due from broker on the statement of assets and liabilities. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. Risks may arise from the potential inability of a counterparty to meet the terms of the contract. The credit/counterparty risk for centrally cleared swaps is generally less than non-centrally cleared swaps, since the clearinghouse, which is the issuer or counterparty to each centrally cleared swap, has robust risk mitigation standards, including the requirement to provide initial and variation margin. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the time it was closed.

Interest Rate Swaps:

The Fund is subject to interest rate risk exposure in the normal course of pursuing its investment objectives. Because the Fund holds fixed rate bonds, the value of these bonds may decrease if interest rates rise. To help hedge against this risk and to maintain its ability to generate income at prevailing market rates, the Fund may enter into interest rate swaps. Interest rate swaps are agreements between two parties to exchange cash flows based on a notional amount. The

28    ^|    AB TAX-AWARE REAL RETURN INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

Fund may elect to pay a fixed rate and receive a floating rate, or, receive a fixed rate and pay a floating rate on a notional amount.

In addition, the Fund may also enter into interest rate swap transactions to preserve a return or spread on a particular investment or portion of its portfolio, or protecting against an increase in the price of securities the Fund anticipates purchasing at a later date. Interest rate swaps involve the exchange by the Fund with another party of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments) computed based on a contractually-based principal (or “notional”) amount. Interest rate swaps are entered into on a net basis (i.e., the two payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the two payments).

During the six months ended October 31, 2023, the Fund held interest rate swaps for hedging purposes.

Inflation (CPI) Swaps:

Inflation swap agreements are contracts in which one party agrees to pay the cumulative percentage increase in a price index (the Consumer Price Index with respect to CPI swaps) over the term of the swap (with some lag on the inflation index), and the other pays a compounded fixed rate. Inflation swaps may be used to protect the net asset value, or NAV, of a Fund against an unexpected change in the rate of inflation measured by an inflation index since the value of these agreements is expected to increase if there are unexpected inflation increases.

During the six months ended October 31, 2023, the Fund held inflation (CPI) swaps for hedging purposes.

Total Return Swaps:

The Fund may enter into total return swaps in order to take a “long” or “short” position with respect to an underlying referenced asset. The Fund is subject to market price volatility of the underlying referenced asset. A total return swap involves commitments to pay interest in exchange for a market linked return based on a notional amount. To the extent that the total return of the security, group of securities or index underlying the transaction exceeds or falls short of the offsetting interest obligation, the Fund will receive a payment from or make a payment to the counterparty.

During the six months ended October 31, 2023, the Fund held total return swaps for hedging purposes.

The Fund typically enters into International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreement”) with its OTC

abfunds.com AB TAX-AWARE REAL RETURN INCOME SHARES    ^|    29

NOTES TO FINANCIAL STATEMENTS (continued)

derivative contract counterparties in order to, among other things, reduce its credit risk to OTC counterparties. ISDA Master Agreements include provisions for general obligations, representations, collateral and events of default or termination. Under an ISDA Master Agreement, the Fund typically may offset with the OTC counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment (close-out netting) in the event of default or termination. In the event of a default by an OTC counterparty, the return of collateral with market value in excess of the Fund’s net liability, held by the defaulting party, may be delayed or denied.

The Fund’s ISDA Master Agreements may contain provisions for early termination of OTC derivative transactions in the event the net assets of the Fund decline below specific levels (“net asset contingent features”). If these levels are triggered, the Fund’s OTC counterparty has the right to terminate such transaction and require the Fund to pay or receive a settlement amount in connection with the terminated transaction. If OTC derivatives were held at period end, please refer to netting arrangements by the OTC counterparty table below for additional details.

During the six months ended October 31, 2023, the Fund had entered into the following derivatives:

Risks Involved in Investing in the Fund

Market Risk—The value of the Fund’s assets will fluctuate as the stock or bond market fluctuates. 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.

Credit Risk—An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security and any accrued interest. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.

Interest-Rate Risk—Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of existing investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest-rate risk is generally greater for fixed-income securities with longer maturities or durations. The Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the recent end

32    ^|    AB TAX-AWARE REAL RETURN INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

of a period of historically low rates and the effects of potential central bank monetary policy, and government fiscal policy, initiatives and resulting market reactions to those initiatives.

Below Investment-Grade Securities Risk—Investments in fixed-income securities with lower ratings (commonly known as “junk bonds”) are subject to a higher probability that an issuer will default or fail to meet its payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments and negative perceptions of the junk bond market generally and may be more difficult to trade than other types of securities.

Duration Risk—Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise.

Municipal Market Risk—This is the risk that special factors may adversely affect the value of municipal securities and have a significant effect on the yield or value of the Fund’s investments in municipal securities. These factors include economic conditions, political or legislative changes, public health crises, uncertainties related to the tax status of municipal securities, and the rights of investors in these securities. To the extent that the Fund invests more of its assets in a particular state’s municipal securities, the Fund may be vulnerable to events adversely affecting that state, including economic, political and regulatory occurrences, court decisions, terrorism, public health crises (including the occurrence of a contagious disease or illness) and catastrophic natural disasters, such as hurricanes, fires or earthquakes. The Fund’s investments in certain municipal securities with principal and interest payments that are made from the revenues of a specific project or facility, and not general tax revenues, may have increased risks. Factors affecting the project or facility, such as local business or economic conditions, could have a significant effect on the project’s ability to make payments of principal and interest on these securities.

In addition, changes in tax rates or the treatment of income from certain types of municipal securities, among other things, could negatively affect the municipal securities markets.

Inflation Risk—This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Fund’s assets can decline as can the value of the Fund’s distributions. This risk is significantly greater for fixed-income securities with longer maturities.

abfunds.com AB TAX-AWARE REAL RETURN INCOME SHARES    ^|    33

NOTES TO FINANCIAL STATEMENTS (continued)

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

Leverage Risk—When the Fund borrows money or otherwise leverages its investments, its performance may be volatile because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s investments. The Fund may create leverage through the use of reverse repurchase arrangements, forward currency exchange contracts, forward commitments, dollar rolls or futures or by borrowing money. The use of other types of derivative instruments by the Fund, such as options and swaps, may also result in a form of leverage. Leverage may result in higher returns to the Fund than if the Fund were not leveraged, but may also adversely affect returns, particularly if the market is declining.

Illiquid Investments Risk—Illiquid investments risk exists when particular investments, such as lower-rated securities, are or become difficult to purchase or sell, possibly preventing the Fund from selling such investments at an advantageous price. The Fund is subject to illiquid investments risk because the market for municipal securities is generally smaller than many other markets. Derivatives and securities involving substantial market and credit risk tend to involve greater illiquid investments risk than most other types of investments.

LIBOR Replacement Risk—The Fund may be exposed to debt securities, derivatives or other financial instruments that recently transitioned from the London Interbank Offered Rate, or “LIBOR,” as a “benchmark” or “reference rate” for various interest rate calculations. LIBOR’s administrator, ICE Benchmark Administration, ceased publishing most LIBOR settings (including some U.S. LIBOR settings) by the end of 2021 and the remaining (and most widely used) U.S. Dollar LIBOR settings after June 30, 2023. The United Kingdom Financial Conduct Authority, which regulates LIBOR, will permit the use of synthetic U.S. Dollar LIBOR rates for non-U.S. contracts through September 30, 2024, but any such rates would be considered non-representative of the underlying market. Since 2018 the Federal Reserve Bank of New York has published the Secured Overnight Financing Rate (referred to as SOFR), which is intended to replace U.S. Dollar LIBOR. SOFR is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities in the repurchase agreement (repo) market. There is no assurance that the composition or characteristics of SOFR or any such alternative reference rate

34    ^|    AB TAX-AWARE REAL RETURN INCOME SHARES abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

will be similar to or produce the same value or economic equivalence as LIBOR or that the market for SOFR-linked financial instruments will have the same volume or liquidity as did the market for LIBOR-linked financial instruments prior to LIBOR’s discontinuance or unavailability. Neither the long-term effects of the LIBOR transition process nor its ultimate success can yet be known.

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, 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 F

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 October 31, 2023.

NOTE G

Distributions to Shareholders

The tax character of distributions to be paid for the year ending April 30, 2024 will be determined at the end of the current fiscal year. The tax character of distributions paid during the fiscal years ended April 30, 2023 and April 30, 2022 were as follows:

	2023		2022
Distributions paid from:
Ordinary income	$	61,828	$	533
Net long-term capital gains		681,098		2,009,261

As of April 30, 2023, the components of accumulated earnings (deficit) on a tax basis were as follows:

Undistributed ordinary income	$	147,607
Undistributed tax-exempt income		127,276
Undistributed capital gains		200,773
Unrealized appreciation (depreciation)		432,986	(a)
Total accumulated earnings (deficit)	$	908,642	(b)

(a) The difference between book-basis and tax-basis unrealized appreciation (depreciation) is attributable primarily to the tax treatment of swaps.

(b) The difference between book-basis and tax-basis components of accumulated earnings (deficit) is attributable primarily to dividends payable.

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 April 30, 2023, the Fund did not have any capital loss carryforwards.

Recent Accounting Pronouncements

In December 2022, the Financial Accounting Standards Board issued an Accounting Standards Update, ASU 2022-06, “Reference Rate Reform (Topic 848)—Deferral of the Sunset Date of Topic 848”. ASU 2022-06 is an amendment to ASU 2020-04, which provided optional guidance to ease the potential accounting burden due to the discontinuation of the LIBOR and other interbank-offered based reference rates and which was effective as of March 12, 2020 through December 31, 2022. ASU 2022-06 extends the effective period through December 31, 2024. Management is currently evaluating the impact, if any, of applying ASU 2022-06.

NOTE I

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.

Operation and Effectiveness of the Fund’s Liquidity Risk Management Program:

In October 2016, the Securities and Exchange Commission (“SEC”) adopted the open-end fund liquidity rule (the “Liquidity Rule”). In June 2018 the SEC adopted a requirement that funds disclose information about the operation and effectiveness of their Liquidity Risk Management Program (“LRMP”) in their reports to shareholders.

One of the requirements of the Liquidity Rule is for the Fund to designate an Administrator of the Fund’s Liquidity Risk Management Program. The Administrator of the Fund’s LRMP is AllianceBernstein L.P., the Fund’s investment adviser (the “Adviser”). The Adviser has delegated the responsibility to its Liquidity Risk Management Committee (the “Committee”).

Another requirement of the Liquidity Rule is for the Fund’s Board of Trustees (the “Fund Board”) to receive an annual written report from the Administrator of the LRMP, which addresses the operation of the Fund’s LRMP and assesses its adequacy and effectiveness. The Adviser provided the Fund Board with such annual report during the first quarter of 2023, which covered the period January 1, 2022 through December 31, 2022 (the “Program Reporting Period”).

The LRMP’s principal objectives include supporting the Fund’s compliance with limits on investments in illiquid assets and mitigating the risk that the Fund will be unable to meet its redemption obligations in a timely manner.

Pursuant to the LRMP, the Fund classifies the liquidity of its portfolio investments into one of the four categories defined by the SEC: Highly Liquid, Moderately Liquid, Less Liquid, and Illiquid. These classifications are reported to the SEC on Form N-PORT.

During the Program Reporting Period, the Committee reviewed whether the Fund’s strategy is appropriate for an open-end structure, incorporating any holdings of less liquid and illiquid assets. If the Fund participated in derivative transactions, the exposure from such transactions were considered in the LRMP.

The Committee also performed an analysis to determine whether the Fund is required to maintain a Highly Liquid Investment Minimum (“HLIM”). The Committee also incorporated the following information when determining the Fund’s reasonably anticipated trading size for purposes of liquidity monitoring: historical net redemption activity, a Fund’s concentration in an issuer, shareholder concentration, investment performance, total net assets, and distribution channels.

The Adviser informed the Fund Board that the Committee believes the Fund’s LRMP is adequately designed, has been implemented as intended,

abfunds.com AB TAX-AWARE REAL RETURN INCOME SHARES    ^|    39

and has operated effectively since its inception. No material exceptions have been noted since the implementation of the LRMP. During the Program Reporting Period, liquidity in all markets was challenged due to rising rates and economic uncertainty. However, markets also remained orderly during the Program Reporting Period. There were no liquidity events that impacted the Fund or its ability to timely meet redemptions during the Program Reporting Period.

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

The disinterested trustees (the “directors”) of AB Corporate Shares (the “Company”) unanimously approved the continuance of the Company’s Advisory Agreement with the Adviser in respect of AB Tax-Aware Real Return Income Shares (the “Fund”) at a meeting held in-person on August 1-2, 2023 (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 noted that the Fund is designed as a vehicle for the wrap fee account market (where investors pay fees to a wrap fee sponsor which pays investment fees and expenses from such fee). The directors also noted that no advisory fee is payable by the Fund to the Adviser, that the Advisory Agreement does not include the reimbursement provision for certain administrative expenses included in the advisory agreements of most of the open-end AB Funds, and that the Adviser is responsible for payment of the Fund’s ordinary expenses. The directors noted that the Company acknowledges in the Advisory Agreement that the Adviser and its affiliates expect to receive compensation from third parties in connection with services provided to the Fund under the Advisory Agreement. The directors further noted that the Adviser receives payments from the wrap fee program sponsors (the “Sponsors”) that use the Fund as an investment vehicle for their clients.

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.

abfunds.com AB TAX-AWARE REAL RETURN INCOME SHARES    ^|    41

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 performing services for the AB Funds. They also noted the professional experience and qualifications of the Fund’s portfolio management team and other senior personnel of the Adviser. 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 2021 and 2022 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. 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 noted that the Fund was not profitable to the Adviser in the periods reviewed.

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. The directors noted that the Adviser is compensated by the Sponsors. 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 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 the Fund’s performance against a broad-based securities market index, in each case for the 1- and 3-year periods ended May 31, 2023 and (in the case of comparisons with the broad-based securities market index) for the period from inception. The directors were cognizant that the Fund was neither designed nor offered as a standalone investment and was intended to serve solely as a component of certain separately managed accounts (“SMAs”). The Adviser had explained that this attribute made it difficult to select an appropriate benchmark for the Fund. At the directors’ request, the Adviser provided information showing the weighting of the Fund in a current SMA and the overall performance of the SMA versus its stated benchmark. Based on their review, the directors concluded that the Fund’s investment performance was acceptable.

Advisory Fees

The directors considered the advisory fee rate payable by the Fund to the Adviser (zero) and information provided by the 15(c) 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 payable by other funds.

The directors noted the unusual arrangements in the Advisory Agreement providing for no advisory fee but were cognizant that the Adviser would be indirectly compensated by the Sponsors for its services to the Fund. The directors reviewed the fee arrangements between the Adviser and each of the current Sponsors and noted that such fees were negotiated on an arm’s length basis and were within the range of fees paid by wrap fee sponsors to other advisers of similar funds. While the Adviser’s fee arrangements with the Sponsors vary, the directors acknowledged the Adviser’s view that a portion of such fees (less the expenses of the Fund

abfunds.com AB TAX-AWARE REAL RETURN INCOME SHARES    ^|    43

paid by the Adviser) may reasonably be viewed as compensating the Adviser for advisory services it provides to the Fund (the “implied fee”) and that the Adviser believes that while the Sponsors pay the Adviser different fee rates, the rate of fee attributable to Fund management at the Fund level is the same for all Sponsors. The directors also considered the fee rate schedules used by other registered investment companies that invest in fixed income securities that are advised by the Adviser.

The Adviser informed the directors that there were no institutional products managed by it that utilize investment strategies similar to those of the Fund.

The directors did not consider comparative expense information for the Fund because the Fund does not bear ordinary expenses.

Economies of Scale

The directors did not consider the extent to which fee levels in the Advisory Agreement for the Fund reflect economies of scale because the Advisory Agreement does not provide for any compensation to be paid to the Adviser by the Fund and the Fund’s expense ratio is zero. They did note, however, that the fee payable to the Adviser by the current Sponsors declines at a breakpoint based on either individual account sizes or on total assets managed by the Adviser for the Sponsor.
