Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) 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.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness 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.

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying consolidated balance sheets of FS KKR Capital Corp. and subsidiaries (the “Company”), including the consolidated schedules of investments, as of December 31, 2025 and 2024, 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, 2025, the financial highlights for each of the five years in the period ended December 31, 2025, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations, changes in net assets, and its cash flows for each of the three years in the period ended December 31, 2025, and the financial highlights for each of the five years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 25, 2026 expressed an unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements and financial highlights based on our audits. We are a public accounting firm registered with the 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 audits 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 and financial highlights are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, 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 and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of investments owned as of December 31, 2025 and 2024, by correspondence with the custodian, loan agents, and borrowers; when replies were not received, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

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 2, 6, and 8 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 less liquid corporate bonds and loans, unlisted equity securities, and derivatives that lack observable market prices. 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, such as selected discount rates, projected future cash flows, and comparable company multiples, to estimate the fair value as of December 31, 2025. This required a high degree of auditor judgment and extensive audit effort, including the need to involve fair value specialists who possess significant valuation experience, to evaluate the appropriateness of the valuation techniques and the significant unobservable inputs, when performing audit procedures to audit management’s estimate of fair value of Level 3 investments.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to valuation techniques and unobservable inputs used by management to estimate the fair value of Level 3 investments included the following, among others:

•We tested the effectiveness of controls over management’s valuation of Level 3 investments, including those related to valuation techniques and significant unobservable inputs.

•We evaluated the appropriateness of the valuation techniques used for Level 3 investments and tested the related significant unobservable inputs by comparing these inputs to external sources. We evaluated the reasonableness of any significant changes in valuation techniques or significant unobservable inputs. For a selected sample of Level 3 investments, we performed these procedures with the assistance of our fair value specialists.

•In instances where the selection of valuation techniques or significant unobservable inputs were more subjective, with the assistance of our fair value specialists, we developed an independent estimate of the fair value and compared our estimates to management’s estimates.

•We evaluated management’s ability to reasonably estimate fair value by comparing management’s historical estimates to subsequent transactions, taking into account changes in market or investment specific conditions, where applicable.

We have served as the auditor of one or more investment companies within the group of investment companies since 2019.

We have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of FS KKR Capital Corp. and subsidiaries (the "Company"), including the consolidated schedules of investments, as of December 31, 2025 and 2024, and the related consolidated statements of operations, changes in net assets, and cash flows, for each of the three years in the period then ended, financial highlights for each of the five years in the period then ended, and the related notes, and in our report dated February 25, 2026, we expressed an unqualified opinion thereon. We have also previously audited, in accordance with the standards of the PCAOB, the consolidated balance sheet, including the consolidated schedules of investments, as of December 31, 2023, 2022, 2021, 2020, and 2019, and the related statements of operations, cash flows, and changes in net assets for the years ended December 31, 2023, 2022, 2021, 2020, and 2019, and the related notes (none of which are presented herein) and we expressed unqualified opinions on those consolidated financial statements. In our opinion, the information set forth in the senior securities table of the Company for each of the five years in the period ended December 31, 2025, appearing on page 66 of this Form 10-K, is fairly stated, in all material respects, in relation to the consolidated financial statements from which it has been derived.
