AB 2020 Form 10-K

Report of Independent Registered Public Accounting Firm To the Board of Directors and Shareholders of AB Private Credit Investors Corporation Opinion on the Financial Statements We have audited the accompanying consolidated statements of assets and liabilities, including the consolidated schedules of investments, of AB Private Credit Investors Corporation and its subsidiaries (the “Fund”) as of December 31, 2020 and 2019, and the related consolidated statements of operations, changes in net assets and cash flows for each of the three years in the period ended December 31, 2020 , including the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Fund as of December 31, 2020 and 2019, and the results of its operations, changes in its net assets and its cash flows for each of the three years in the period ended December 31, 2020 in conformity with accounting principles generally accepted in the United States of America. Basis for Opinion These consolidated financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our procedures included confirmation of securities owned as of December 31, 2020 and 2019 by correspondence with the administrative agents and portfolio company investees. We believe that our audits provide a reasonable basis for our opinion. /s/ PricewaterhouseCoopers LLP New York, New York March 30, 2021 We have served as the Fund’s auditor since 2016. 99
