ALLIANCEBERNSTEIN HOLDING LP

Disclosure Controls and Procedures

Each of AB Holding and AB maintains a system of disclosure controls and procedures that is designed to ensure that information required to be disclosed in our reports under the Exchange Act is (i) recorded, processed, summarized and reported in a timely manner, and (ii) accumulated and communicated to management, including the Chief Executive Officer (“CEO”) and the Interim Chief Financial Officer (“CFO”), to permit timely decisions regarding our disclosure.

As of the end of the period covered by this report, management carried out an evaluation, under the supervision and with the participation of the CEO and the CFO, of the effectiveness of the design and operation of disclosure controls and procedures. Based on this evaluation, the CEO and the CFO concluded that the disclosure controls and procedures are effective.

Management’s Report on Internal Control Over Financial Reporting

Management acknowledges its responsibility for establishing and maintaining adequate internal control over financial reporting for each of AB Holding and AB.

Internal control over financial reporting is a process designed by, or under the supervision of, a company’s CEO and CFO, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and includes those policies and procedures that:

•Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;

•Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with US GAAP and receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

•Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those internal control systems determined to be effective can provide only reasonable assurance with respect to the reliability of financial statement preparation and presentation. Because of these inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness of internal control to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of AB Holding’s and AB’s internal control over financial reporting as of December 31, 2023. In making its assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013) (the“COSO criteria”).

Based on its assessment, management concluded that, as of December 31, 2023, each of AB Holding and AB maintained effective internal control over financial reporting based on the COSO criteria.

PricewaterhouseCoopers LLP (PCAOB ID No.238), the independent registered public accounting firm that audited the 2023 financial statements included in this Form 10-K, has issued an attestation report on the effectiveness of each of AB Holding’s and AB’s internal control over financial reporting as of December 31, 2023. The reports pertaining to AB Holding and AB each can be foundin Item 8 of this Form 10-K.

Changes in Internal Control Over Financial Reporting

No changes in our internal control over financial reporting occurred during the fourth quarter of 2023 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
