REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Stellus Capital Investment Corporation

Opinion on the financial statements

We have audited the accompanying consolidated statement of assets and liabilities of Stellus Capital Investment Corporation and subsidiaries (the “Company”), including the consolidated schedule of investments, as of December 31, 2024, the related consolidated statements of operations, changes in net assets, and cash flows for the year ended December 31, 2024, the financial highlights (in Note 8) for the year ended December 31, 2024, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024, and the results of its operations, changes in its net assets, and its cash flows for the year ended December 31, 2024, and its financial highlights for the year ended December 31, 2024 in conformity with accounting principles generally accepted in the United States of America.

Basis for opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. 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 Company 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 audit 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 financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, 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 Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the 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 financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

Critical audit matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Fair Value – Level 3 Investments – Refer to Notes 1 and 6 to the financial statements

Critical Audit Matter Description

The Company held investments classified as Level 3 investments under accounting principles generally accepted in the United States of America. These investments included debt and equity securities with unique contract terms and conditions and/or complexity that considers a combination of multiple levels of market and asset specific inputs. The

valuation techniques used in estimating the fair value of these investments vary and certain significant inputs used were unobservable.

We identified the valuation of Level 3 investments as a critical audit matter because of the judgments necessary for management to select valuation techniques and to use significant unobservable inputs to estimate the fair value. This required a high degree of auditor judgement and extensive audit effort to audit management’s estimate of fair value of Level 3 investments, including the need to involve fair value specialists possessing relevant valuation experience to evaluate the appropriateness of the valuation techniques and the significant unobservable inputs used in the valuation of certain investments.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the fair value of certain Level 3 investments included the following, among others:
