Management’s Discussion and Analysis should be read in conjunction with ITEM 8. CONSOLIDATED FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA. This discussion contains forward-looking statements and involves numerous risks and uncertainties, including, but not limited to, those described in “ITEM 1A. RISK FACTORS.” Actual results may differ materially from those contained in any forward-looking statements.

Overview

Sixth Street Specialty Lending, Inc. is a Delaware corporation formed on July 21, 2010. The Adviser is our external manager. We have four wholly owned subsidiaries, TC Lending, LLC, a Delaware limited liability company, which holds a California finance lender and broker license, Sixth Street SL SPV, LLC, a Delaware limited liability company, Sixth Street SL Holding, LLC, a Delaware limited liability company, and Sixth Street Specialty Lending Sub, LLC, a Cayman Islands limited liability company.

We have elected to be regulated as a BDC under the 1940 Act and as a RIC under the Code. We made our BDC election on April 15, 2011. As a result, we are required to comply with various statutory and regulatory requirements, such as:

the requirement to invest at least 70% of our assets in “qualifying assets”;

source of income limitations;

asset diversification requirements; and

the requirement to distribute (or be treated as distributing) in each taxable year at least 90% of our investment company taxable income and tax-exempt interest for that taxable year.

Our shares are listed on the NYSE under the symbol “TSLX.”

Our Investment Framework

Our investment objective is to generate current income by targeting investments with favorable “risk-adjusted returns,” which are

expected returns that are adjusted based on the levels of risk associated with the investments. Since we began our investment activities in July 2011, through December 31, 2025, we have originated more than $53.3 billion aggregate principal amount of investments and retained approximately $11.8 billion aggregate principal amount of these investments on our balance sheet prior to any subsequent exits and repayments. We seek to generate current income primarily in U.S.-domiciled middle-market companies through direct investment originations of senior secured loans and, to a lesser extent, originations of mezzanine and unsecured loans and investments in corporate bonds, equity securities, and other instruments.

By “middle-market companies,” we mean companies that have annual EBITDA, which we believe is a useful proxy for cash flow, of $10 million to $250 million, although we may invest in larger or smaller companies on occasion. As of December 31, 2025, our core portfolio companies, which exclude certain investments that fall outside of our typical borrower profile and represent 87.9% of our total investments based on fair value, had weighted average annual revenue of $449.2 million and weighted average annual EBITDA of $127.3 million. As of December 31, 2025, our core portfolio companies had a median annual revenue of $159.4 million and a median annual EBITDA of $48.0 million.

We invest in first-lien debt, second-lien debt, mezzanine and unsecured debt and equity and other investments. Our first-lien debt may include stand-alone first-lien loans; “last out” first-lien loans, which are loans that have a secondary priority behind super-senior “first out” first-lien loans; “unitranche” loans, which are loans that combine features of first-lien, second-lien and mezzanine debt, generally in a first-lien position; and secured corporate bonds with similar features to these categories of first-lien loans. Our second-lien debt may include secured loans, and, to a lesser extent, secured corporate bonds, with a secondary priority behind first-lien debt.

The debt in which we invest typically is not rated by any rating agency, but if these instruments were rated, they would likely receive a rating of below investment grade (that is, below BBB- or Baa3 as defined by Standard & Poor’s and Moody’s Investors Services, respectively), which is often referred to as “junk.”

The companies in which we invest use our capital to support organic growth, acquisitions, market or product expansion and recapitalizations (including restructurings). As of December 31, 2025, the largest single investment based on fair value represented 2.4% of our total investment portfolio.

As of December 31, 2025, the average investment size in each of our portfolio companies was approximately $23.4 million based on fair value. Portfolio companies includes investments in structured credit investments, which include each series of collateralized loan obligation as a portfolio company investment. When excluding investments in structured credit investments, the average investment in our remaining portfolio companies was approximately $30.4 million as of December 31, 2025.

Through our Adviser, we consider potential investments utilizing a four-tiered investment framework and against our existing portfolio as a whole:

Business and sector selection. We focus on companies with enterprise value between $50 million and $1 billion. When reviewing potential investments, we seek to invest in businesses with high marginal cash flow, recurring revenue streams and where we believe credit quality will improve over time. We look for portfolio companies that we think have a sustainable competitive advantage in growing industries or distressed situations. We also seek companies where our investment will have a low loan-to-value ratio.

We currently do not limit our focus to any specific industry and we may invest in larger or smaller companies on occasion. We classify the industries of our portfolio companies by end-market (such as healthcare, and business services) and not by the products or services (such as software) directed to those end-markets.

As of December 31, 2025, the largest industry represented 18.3% of our total investment portfolio based on fair value.

Investment Structuring. We focus on investing at the top of the capital structure and protecting that position. As of December 31, 2025, approximately 90.1% of our portfolio was invested in secured debt, including 89.2% in first-lien debt investments. We carefully perform diligence and structure investments to include strong investor covenants. As a result, we structure investments with a view to creating opportunities for early intervention in the event of non-performance or stress. In addition, we seek to retain effective voting control in investments over the loans or particular class of securities in which we invest through maintaining affirmative voting positions or negotiating consent rights that allow us to retain a blocking position. We also aim for our loans to mature on a medium term, between two to seven years after origination. For the year ended December 31, 2025, the weighted average term on new investment commitments in new portfolio companies was 6.4 years.

Deal Dynamics. We focus on, among other deal dynamics, direct origination of investments, where we identify and lead the investment transaction. A substantial majority of our portfolio investments are sourced through our direct or proprietary relationships.

Risk Mitigation. We seek to mitigate non-credit-related risk on our returns in several ways, including call protection provisions to protect future interest income. As of December 31, 2025, we had call protection on 78.9% of our debt investments based on fair value, with weighted average call prices of 107.9% for the first year, 104.3% for the second year and 101.7% for the third year, in each case from the date of the initial investment. As of December 31, 2025, 96.3% of our debt investments based on fair value bore interest at floating rates, with 100.0% of these subject to interest rate floors, which we believe helps act as a portfolio-wide hedge against inflation.

Relationship with our Adviser and Sixth Street

Our Adviser is a Delaware limited liability company. Our Adviser acts as our investment adviser and administrator and is a registered investment adviser with the SEC under the Advisers Act. Our Adviser sources and manages our portfolio through a dedicated team of investment professionals predominately focused on direct lending, which we refer to as our Investment Team. Our Investment Team is led by our Adviser’s Co-Founding Partner, Co-President and Co-Chief Investment Officer Joshua Easterly, our Co-Head of Sixth Street Direct Lending and Co-Head of Growth Robert “Bo” Stanley, Co-Head of Direct Lending Michael Griffin, and our Adviser’s Co-Founding Partner, Chief Executive Officer, and Co-Chief Investment Officer Alan Waxman, all of whom have substantial experience in credit origination, underwriting and asset management. Our investment decisions are made by our Investment Review Committee, which includes senior personnel of our Adviser and affiliates of Sixth Street Partners, LLC, or “Sixth Street.”

Sixth Street is a global investment business with over $125 billion of assets under management as of December 31, 2025. Sixth Street’s direct lending platforms include Sixth Street Specialty Lending and Sixth Street Lending Partners, which are aimed at U.S. middle-market loan originations and upper middle-market loan originations, respectively, Sixth Street Specialty Lending Europe, which is aimed at European middle-market loan originations. Additional Sixth Street core platforms include Sixth Street TAO, which has the flexibility to invest across all of Sixth Street’s private credit market investments, Sixth Street Opportunities, which focuses on actively managed opportunistic investments across the credit cycle, Sixth Street Credit Market Strategies, which is the firm’s “public-side” credit investment platform focused on investment opportunities in broadly syndicated leveraged loan markets, Sixth Street Growth, which provides financing solutions to growing companies, Sixth Street Fundamental Strategies, which primarily invests in secondary credit, and Sixth Street Agriculture, which invests in niche agricultural opportunities. Sixth Street has a long-term oriented,

highly flexible capital base that allows it to invest across industries, geographies, capital structures and asset classes. Sixth Street has extensive experience with highly complex, global public and private investments executed through primary originations, secondary market purchases and restructurings, and has a team of over 740 investment and operating professionals. As of December 31, 2025, seventy-eight (78) of these personnel are dedicated to direct lending, including sixty-three (63) investment professionals.

Our Adviser consults with Sixth Street in connection with a substantial number of our investments. The Sixth Street platform provides us with a breadth of large and scalable investment resources. We believe we benefit from Sixth Street’s market expertise, insights into industry, sector and macroeconomic trends and intensive due diligence capabilities, which help us discern market conditions that vary across industries and credit cycles, identify favorable investment opportunities and manage our portfolio of investments. Sixth Street and its affiliates will refer all middle-market loan origination activities for companies domiciled in the United States to us and conduct those activities through us. The Adviser will determine whether it would be permissible, advisable or otherwise appropriate for us to pursue a particular investment opportunity allocated to us.

On May 6, 2025, we, the Adviser and certain of our affiliates were granted an exemptive order from the SEC that allows us to co-invest, subject to certain conditions, with certain of our affiliates (including affiliates of Sixth Street) in middle-market loan origination activities for companies domiciled in the United States.

We believe our ability to co-invest with Sixth Street affiliates is particularly useful where we identify larger capital commitments than otherwise would be appropriate for us. We expect that with the ability to co-invest with Sixth Street affiliates we will continue to be able to provide “one-stop” financing to a potential portfolio company in these circumstances, which may allow us to capture opportunities where we alone could not commit the full amount of required capital or would have to spend additional time to locate unaffiliated co-investors.

Under the terms of the Investment Advisory Agreement and Administration Agreement, the Adviser’s services are not exclusive, and the Adviser is free to furnish similar or other services to others, so long as its services to us are not impaired. Under the terms of the Investment Advisory Agreement, we will pay the Adviser the base management fee (the “Management Fee”), and may also pay certain incentive fees (the “Incentive Fees”).

Under the terms of the Administration Agreement, the Adviser also provides administrative services to us. These services include providing office space, equipment and office services, maintaining financial records, preparing reports to stockholders and reports filed with the SEC, and managing the payment of expenses and the oversight of the performance of administrative and professional services rendered by others. Certain of these services are reimbursable to the Adviser under the terms of the Administration Agreement.

Key Components of Our Results of Operations

Investments

We focus primarily on the direct origination of loans to middle-market companies domiciled in the United States.

Our level of investment activity (both the number of investments and the size of each investment) can and does vary substantially from period to period depending on many factors, including the amount of debt and equity capital generally available to middle-market companies, the level of merger and acquisition activity for such companies, the general economic environment and the competitive environment for the types of investments we make.

In addition, as part of our risk strategy on investments, we may reduce certain levels of investments through partial sales or syndication to additional investors.

Revenues

We generate revenues primarily in the form of interest income from the investments we hold. In addition, we may generate income from dividends on direct equity investments, capital gains on the sale of investments and various loan origination and other fees. Our debt investments typically have a term of two to seven years, and, as of December 31, 2025, 96.3% of these investments based on fair value bore interest at a floating rate, with 100.0% of these subject to interest rate floors. Interest on debt investments is generally payable monthly or quarterly. Some of our investments provide for deferred interest payments or PIK interest. For the years ended December 31, 2025, 2024 and 2023, 5.7%, 6.1% and 4.5%, respectively, of our total investment income was comprised of PIK interest.

Changes in our net investment income are primarily driven by the spread between the payments we receive from our investments in our portfolio companies against our cost of funding, rather than by changes in interest rates. Our investment portfolio primarily

consists of floating rate loans, and our Revolving Credit Facility, 2026 Notes 2028 Notes, 2029 Notes, and 2030 Notes after taking into account the effect of the interest rate swaps we have entered into in connection with these securities, all bear interest at floating rates. Macro trends in base interest rates like SOFR or other reference rates may affect our net investment income over the long term. However, because we generally originate loans to a limited number of portfolio companies each quarter, and those investments also vary in size, our results in any given period—including the interest rate on investments that were sold or repaid in a period compared to the interest rate of new investments made during that period—often are idiosyncratic, and reflect the characteristics of the particular portfolio companies that we invested in or exited during the period and not necessarily any trends in our business.

In addition to interest income, our net investment income is also driven by prepayment and other fees, which also can vary significantly from quarter to quarter. The level of prepayment fees is generally correlated to the movement in credit spreads and risk premiums, but also will vary based on corporate events that may take place at an individual portfolio company in a given period—e.g., merger and acquisition activity, initial public offerings and restructurings. As noted above, generally a small but varied number of portfolio companies may make prepayments in any quarter, meaning that changes in the amount of prepayment fees received can vary significantly between periods and can vary without regard to underlying credit trends.

Loan origination fees, original issue discount and market discount or premium are capitalized, and we accrete or amortize such amounts as interest income using the effective interest method for term instruments and the straight-line method for revolving or delayed draw instruments. Repayments of our debt investments can reduce interest income from period to period. We record prepayment premiums on loans as interest income when earned. We also may generate revenue in the form of commitment, amendment, structuring, syndication or due diligence fees, fees for providing managerial assistance and consulting fees. The frequency or volume of these items of revenue may fluctuate significantly.

Dividend income on common equity investments is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies.

Our portfolio activity also reflects the proceeds of sales of investments. We recognize realized gains or losses on investments based on the difference between the net proceeds from the disposition and the amortized cost basis of the investment without regard to unrealized gains or losses previously recognized. We record current period changes in fair value of investments that are measured at fair value as a component of the net change in unrealized gains (losses) on investments in the Consolidated Statements of Operations.

Expenses

Our primary operating expenses include the payment of fees to our Adviser under the Investment Advisory Agreement, expenses reimbursable under the Administration Agreement and other operating costs described below. Additionally, we pay interest expense on our outstanding debt. We bear all other costs and expenses of our operations, administration and transactions, including those relating to:

calculating individual asset values and our net asset value (including the cost and expenses of any independent valuation firms);

expenses, including travel expenses, incurred by the Adviser, or members of our Investment Team, or payable to third parties, in respect of due diligence on prospective portfolio companies and, if necessary, in respect of enforcing our rights with respect to investments in existing portfolio companies;

the costs of any public offerings of our common stock and other securities, including registration and listing fees;

the Management Fee and any Incentive Fee;

certain costs and expenses relating to distributions paid on our shares;

administration fees payable under our Administration Agreement;

costs of preparing financial statements and maintaining books and records and filing reports or other documents with the SEC (or other regulatory bodies) and other reporting and compliance costs, and the compensation of professionals responsible for the preparation of the foregoing, including the allocable portion of the compensation of our Chief Financial Officer, Chief Compliance Officer and other professionals who spend time on those related activities (based on the percentage of time those individuals devote, on an estimated basis, to our business and affairs);

debt service and other costs of borrowings or other financing arrangements;

the Adviser’s allocable share of costs incurred in providing significant managerial assistance to those portfolio companies that request it;

amounts payable to third parties relating to, or associated with, making or holding investments;

transfer agent and custodial fees;

costs of hedging;

commissions and other compensation payable to brokers or dealers;

taxes;

Independent Director fees and expenses;

the costs of any reports, proxy statements or other notices to our stockholders (including printing and mailing costs), the costs of any stockholders’ meetings and the compensation of investor relations personnel responsible for the preparation of the foregoing and related matters;

our fidelity bond;

directors and officers/errors and omissions liability insurance, and any other insurance premiums;

indemnification payments;

direct costs and expenses of administration, including audit, accounting, consulting and legal costs; and

all other expenses reasonably incurred by us in connection with making investments and administering our business.

We expect that during periods of asset growth, our general and administrative expenses will be relatively stable or will decline as a percentage of total assets, and will increase as a percentage of total assets during periods of asset declines.

Leverage

While as a BDC the amount of leverage that we are permitted to use is limited in significant respects, we use leverage to increase our ability to make investments. The amount of leverage we use in any period depends on a variety of factors, including cash available for investing, the cost of financing and general economic and market conditions, however, under the 1940 Act, our total borrowings are limited so that our asset coverage ratio cannot fall below 150% immediately after any borrowing, as defined in the 1940 Act. In any period, our interest expense will depend largely on the extent of our borrowing and we expect interest expense will increase as we increase leverage over time within the limits of the 1940 Act. In addition, we may dedicate assets as collateral to financing facilities from time to time.

Market Trends

We believe trends in the middle-market lending environment, including the limited availability of capital from traditional regulated financial institutions, strong demand for debt capital and specialized lending requirements, are likely to continue to create favorable opportunities for us to invest at attractive risk-adjusted rates.

Subsequent to the global financial crisis, the implementation of regulatory changes such as Basel III requirements, Leverage Lending Guidance, and the Volcker Rule, tightened risk appetites and reduced the capacity of traditional lenders to serve middle-market companies. We believe that these dynamics create a significant opportunity for us to directly originate investments. We also believe that the large amount of uninvested capital held by private equity firms will continue to drive deal activity, which may in turn create additional demand for debt capital.

This market dynamic is further exacerbated by the specialized due diligence and underwriting capabilities, as well as extensive ongoing monitoring, required for middle-market lending. We believe middle-market lending is generally more labor-intensive than lending to larger companies due to smaller investment sizes and the lack of publicly available information on these companies. As a result, the opportunities for dedicated private lenders such as us has continued to expand.

An imbalance between the supply of, and demand for, middle-market debt capital creates attractive pricing dynamics for investors such as BDCs. The negotiated nature of middle-market financings also generally provides for more favorable terms to the lenders, including stronger covenant and reporting packages, better call protection and lender-protective change of control provisions. We believe that BDCs have flexibility to develop loans that reflect each borrower’s distinct situation, provide long-term relationships and a potential source for future capital, which renders BDCs, including us, attractive lenders.

Loans are generally placed on non-accrual status when principal or interest payments are past due 30 days or more or when management has reasonable doubt that the borrower will pay principal or interest in full. Accrued and unpaid interest is generally reversed when a loan is placed on non-accrual status. Non-accrual loans are restored to accrual status when past due principal and interest has been paid and, in management’s judgment, the borrower is likely to make principal and interest payments in the future. Management may determine to not place a loan on non-accrual status if, notwithstanding any failure to pay, the loan has sufficient collateral value and is in the process of collection. See “–Critical Accounting Estimates – Interest and Dividend Income Recognition.”

The Adviser monitors our portfolio companies on an ongoing basis. The Adviser monitors the financial trends of each portfolio company to determine if it is meeting its business plans and to assess the appropriate course of action for each company. The Adviser has a number of methods of evaluating and monitoring the performance of our investments, which may include the following:

assessment of success of the portfolio company in adhering to its business plan and compliance with covenants;

periodic and regular contact with portfolio company management and, if appropriate, the financial or strategic sponsor, to discuss financial position, requirements and accomplishments;

comparisons to other companies in the industry;

attendance at, and participation in, board meetings; and

review of monthly and quarterly financial statements and financial projections for portfolio companies.

As part of the monitoring process, the Adviser regularly assesses the risk profile of each of our investments and, on a quarterly basis, grades each investment on a risk scale of 1 to 5. Risk assessment is not standardized in our industry and our risk assessment may not be comparable to ones used by our competitors. Our assessment is based on the following categories:

An investment is rated 1 if, in the opinion of the Adviser, it is performing as agreed and there are no concerns about the portfolio company’s performance or ability to meet covenant requirements. For these investments, the Adviser generally prepares monthly reports on investment performance and intensive quarterly asset reviews.

An investment is rated 2 if it is performing as agreed, but, in the opinion of the Adviser, there may be concerns about the company’s operating performance or trends in the industry. For these investments, in addition to monthly reports and quarterly asset reviews, the Adviser also researches any areas of concern with the objective of early intervention with the portfolio company.

An investment will be assigned a rating of 3 if it is paying its obligations to us as agreed but a material covenant violation is expected. For these investments, in addition to monthly reports and quarterly asset reviews, the Adviser also adds the investment to its “watch list” and researches any areas of concern with the objective of early intervention with the portfolio company.

An investment will be assigned a rating of 4 if a material covenant has been violated, but the company is making its scheduled payments on its obligations to us. For these investments, the Adviser generally prepares a bi-monthly asset review email and generally has monthly meetings with the portfolio company’s senior management. For investments where there have been material defaults, including bankruptcy filings, failures to achieve financial performance requirements or failure to maintain liquidity or loan-to-value requirements, the Adviser often will take immediate action to protect its position. These remedies may include negotiating for additional collateral, modifying investment terms or structure, or payment of amendment and waiver fees.

A rating of 5 indicates an investment is in default on its interest and/or principal payments. For these investments, our Adviser reviews the investments on a bi-monthly basis and, where possible, pursues workouts that achieve an early resolution to avoid further deterioration of our investment. The Adviser retains legal counsel and takes actions to preserve our rights, which may include working with the portfolio company to have the default cured, to have the investment restructured or to have the investment repaid through a consensual workout. Investments that carry a rating of 5 would typically indicate the position has been placed on non-accrual status (for investments that otherwise would be income producing).

The following table shows the distribution of our investments on the 1 to 5 investment performance rating scale at fair value as of December 31, 2025 and December 31, 2024. Investment performance ratings are accurate only as of those dates and may change due to subsequent developments relating to a portfolio company’s business or financial condition, market conditions or developments, and other factors.

Structured Credit Partners JV, LLC (“SCP”)

On December 23, 2025, affiliates of Sixth Street, including us, and affiliates of Carlyle entered into the Limited Liability Company Agreement, to co-manage SCP, a joint venture focused on investing in broadly syndicated first lien senior secured loans, financed with long-term, non-mark-to-market, and predominantly investment grade rated CLO debt managed by affiliates of Sixth Street or Carlyle on a no-fee basis. SCP is managed by a board of managers, consisting of an equal number of representatives appointed by the Sixth Street-affiliated members of SCP and the Carlyle-affiliated members of SCP and which acts unanimously. Portfolio construction and investment decisions must be unanimously approved by SCP’s investment committee, as delegated by SCP’s board of managers. Our investment in SCP is made with certain of our affiliates in accordance with the terms of the exemptive relief that we received from the SEC. We do not consolidate our non-controlling interest in SCP. As of December 31, 2025, SCP had not commenced operations and no capital had been contributed to SCP.

Interest from investments, which includes amortization of upfront fees and prepayment fees, decreased from $423.0 million for the year ended December 31, 2024 to $400.8 million for the year ended December 31, 2025. The decrease in interest from investments was primarily the result of a decrease in reference rates for the year ended December 31, 2025 compared to 2024. Paid-in-kind interest income decreased from $29.3 million for the year ended December 31, 2024 to $25.6 million for the year ended December 31, 2025 due to decreased PIK election. Dividend income decreased from $11.7 million for the year ended December 31, 2024 to $2.3 million for the year ended December 31, 2025 due to decreased investments in dividend yielding securities in 2025. Other income increased from $18.5 million for the year ended December 31, 2024 to $20.3 million for the year ended December 31, 2025, primarily due to increased miscellaneous fees earned during 2025.

Interest from investments, which includes amortization of upfront fees and prepayment fees, increased from $399.1 million for the year ended December 31, 2023 to $423.0 million for the year ended December 31, 2024. The increase in interest from investments was primarily the result of a larger average portfolio size for the year ended December 31, 2024 compared to the same period in 2023. Paid-in-kind interest income increased from $19.7 million for the year ended December 31, 2023 to $29.3 million for the year ended December 31, 2024 due to increased PIK election. Dividend income increased from $4.2 million for the year ended December 31, 2023 to $11.7 million for the year ended December 31, 2024 due to increased investments in dividend yielding securities in 2024.

Other income increased from $15.1 million for the year ended December 31, 2023 to $18.5 million for the year ended December 31, 2024, primarily due to increased amendment and other miscellaneous fees earned during 2024.

Interest

Interest expense, including other debt financing expenses, decreased from $154.2 million for the year ended December 31, 2024 to $129.6 million for the year ended December 31, 2025. This decrease was primarily due to a decrease in the average interest rate on our debt outstanding and a decrease in the average debt outstanding from $1,882.7 million for the year ended December 31, 2024 to $1,880.3 million for the year ended December 31, 2025. The average interest rate on our debt outstanding decreased from 7.5% for the year ended December 31, 2024 to 6.2% for the year ended December 31, 2025 due to a change in SOFR rates and the mix of our debt financing sources.

Interest expense, including other debt financing expenses, increased from $133.7 million for the year ended December 31, 2023 to $154.1 million for the year ended December 31, 2024. This increase was primarily due to an increase in the average interest rate on our debt outstanding and an increase in the average debt outstanding from $1,705.6 million for the year ended December 31, 2023 $1,882.7 million for the year ended December 31, 2024. The average interest rate on our debt outstanding increased from 7.3% for the year ended December 31, 2023 to 7.5% for the year ended December 31, 2024 due to a change in the mix of our debt financing sources.

Management Fees

Management Fees (gross of waivers) increased from $51.8 million for the year ended December 31, 2024 to $52.2 million for the year ended December 31, 2025 due to an increase in average assets. Management Fees (net of waivers) increased from $50.3 million for the year ended December 31, 2024 to $50.9 million for the year ended December 31, 2025.

As of December 31, 2025, these accrued Incentive Fees are not contractually payable to the Adviser.

Professional Fees and Other General and Administrative Expenses

Professional fees increased from $7.5 million for the year ended December 31, 2024 to $8.3 million for the year ended December 31, 2025 due to higher legal and audit related fees. Other general and administrative fees increased from $5.5 million for the year ended December 31, 2024 to $5.6 million for the year ended December 31, 2025.

Professional fees increased from $7.3 million for the year ended December 31, 2023 to $7.5 million for the year ended December 31, 2024 due to higher legal fees, higher independent third-party valuation firm fees and higher sub-agent administration costs due to a larger portfolio. Other general and administrative fees increased from $5.3 million for the year ended December 31, 2023 to $5.5 million for the year ended December 31, 2024.

Income Taxes, Including Excise Taxes

We have elected to be treated as a RIC under Subchapter M of the Code, and we intend to operate in a manner so as to continue to qualify for the tax treatment applicable to RICs. To qualify as a RIC, we must, among other things, distribute to our stockholders in each taxable year generally at least 90% of our investment company taxable income, as defined by the Code, and net tax-exempt income for that taxable year. To maintain our RIC status, we, among other things, have made and intend to continue to make the requisite distributions to our stockholders, which generally relieve us from corporate-level U.S. federal income taxes.

Depending on the level of taxable income earned in a tax year, we can be expected to carry forward taxable income (including net capital gains, if any) in excess of current year dividend distributions from the current tax year into the next tax year and pay a nondeductible 4% U.S. federal excise tax on such taxable income, as required. To the extent that we determine that our estimated current year annual taxable income will be in excess of estimated current year dividend distributions from such income, we accrue excise tax on estimated excess taxable income.

For the calendar years ended December 31, 2025, December 31, 2024 and December 31, 2023 we recorded a net expense of $5.3 million, $3.9 million and $2.4 million, respectively, for U.S. federal excise tax and other taxes.

For the calendar years ended December 31, 2025, December 31, 2024 and December 31, 2023 we recorded a deferred tax benefit of $0.5 million, a deferred tax liability of $2.6 million, and a deferred tax benefit of $0.6 million respectively. For the calendar year ended December 31, 2025 we recognized a tax expense of $0.9 million pertaining to net realized gains.

Realized Gross Internal Rate of Return

Since we began investing in 2011 through December 31, 2025, weighted by capital invested, our exited investments have generated an average realized gross internal rate of return to us of 17.1% (based on total capital invested of $9.1 billion and total proceeds from these exited investments of $11.7 billion). Ninety-two percent of these exited investments resulted in a realized gross internal rate of return to us of 10% or greater.

Gross IRR, with respect to an investment, is calculated based on the dates that we invested capital and dates we received distributions, regardless of when we made distributions to our stockholders. Initial investments are assumed to occur at time zero, and all cash flows are deemed to occur on the fifteenth of each month in which they occur.

Gross IRR reflects historical results relating to our past performance and is not necessarily indicative of our future results. In addition, gross IRR does not reflect the effect of Management Fees, expenses, Incentive Fees or taxes borne, or to be borne, by us or our stockholders, and would be lower if it did.

Average gross IRR is the average of the gross IRR for each of our exited investments (each calculated as described above), weighted by the total capital invested for each of those investments.

Average gross IRR on our exited investments reflects only invested and realized cash amounts as described above, and does not reflect any unrealized gains or losses in our portfolio.

Internal rate of return, or IRR, is a measure of our discounted cash flows (inflows and outflows). Specifically, IRR is the discount rate at which the net present value of all cash flows is equal to zero. That is, IRR is the discount rate at which the present value of total capital invested in each of our investments is equal to the present value of all realized returns from that investment. Our IRR calculations are unaudited.

Capital invested, with respect to an investment, represents the aggregate cost basis allocable to the realized or unrealized portion of the investment, net of any upfront fees paid at closing for the term loan portion of the investment. Capital invested also includes realized losses on hedging activity, with respect to an investment, which represents any inception-to-date realized losses on foreign currency forward contracts allocable to the investment, if any.

Realized returns, with respect to an investment, represents the total cash received with respect to each investment, including all amortization payments, interest, dividends, prepayment fees, upfront fees, administrative fees, agent fees, amendment fees, accrued interest, and other fees and proceeds. Realized returns also include realized gains on hedging activity, with respect to an investment, which represents any inception-to-date realized gains on foreign currency forward contracts allocable to the investment, if any.

Interest Rate and Foreign Currency Hedging

We use interest rate swaps to hedge our fixed rate debt and certain fixed rate investments. We have designated certain interest rate swaps to be in a hedge accounting relationship. See Note 2 for additional disclosure regarding our accounting for derivative instruments designated in a hedge accounting relationship. See Note 5 for additional disclosure regarding these derivative instruments and the interest payments paid and received. See Note 7 for additional disclosure regarding the carrying value of our debt.

Our current approach to hedging the foreign currency exposure in our non-U.S. dollar denominated investments is primarily to borrow the par amount in local currency under our Revolving Credit Facility to fund these investments. For the years ended December 31, 2025, December 31, 2024 and December 31, 2023, we had $35.9 million of unrealized losses, $13.4 million of unrealized gains and $6.0 million of unrealized losses, respectively, on the translation of our non-U.S. dollar denominated debt into U.S. dollars; such amounts approximate the corresponding unrealized gains and losses on the translation of our non-U.S. dollar denominated investments into U.S. dollars for the years ended December 31, 2025, December 31, 2024 and December 31, 2023. See Note 2 for additional disclosure regarding our accounting for foreign currency. See Note 7 for additional disclosure regarding the amounts of outstanding debt denominated in each foreign currency at December 31, 2025. See our Consolidated Schedule of Investments for additional disclosure regarding the foreign currency amounts (in both par and fair value) of our non-U.S. dollar denominated investments.

Financial Condition, Liquidity and Capital Resources

Our liquidity and capital resources are derived primarily from proceeds from equity issuances, advances from our credit facilities, and cash flows from operations. The primary uses of our cash and cash equivalents are:

investments in portfolio companies and other investments and to comply with certain portfolio diversification requirements;

the cost of operations (including paying our Adviser);

debt service, repayment, and other financing costs; and

cash dividends to the holders of our shares.

We intend to continue to generate cash primarily from cash flows from operations, future borrowings and future offerings of securities. We may from time to time enter into additional debt facilities, increase the size of existing facilities or issue debt securities. Any such incurrence or issuance would be subject to prevailing market conditions, our liquidity requirements, contractual and regulatory restrictions and other factors. In accordance with the 1940 Act, with certain limited exceptions, we are only allowed to incur borrowings, issue debt securities or issue preferred stock if immediately after the borrowing or issuance our ratio of total assets (less total liabilities other than indebtedness) to total indebtedness plus preferred stock, is at least 150%. For more information, see “ Key Components of Our Results of Operations — Leverage ” above. As of December 31, 2025 and December 31, 2024, our asset coverage ratio was 191.5% and 182.5%, respectively. We carefully consider our unfunded commitments for the purpose of planning our capital resources and ongoing liquidity, including our financial leverage. Further, we maintain sufficient borrowing capacity within the 150% asset coverage limitation under the 1940 Act and the asset coverage limitation under our credit facilities to cover any outstanding unfunded commitments we are required to fund.

Cash and cash equivalents as of December 31, 2025, taken together with cash available under our credit facilities, is expected to be sufficient for our investing activities and to conduct our operations in the near term. As of December 31, 2025, we had approximately $1.1 billion of availability on our Revolving Credit Facility, subject to asset coverage limitations.

As of December 31, 2025, we had $19.7 million in cash and cash equivalents, including $16.7 million of restricted cash. During the year ended December 31, 2025, cash provided by operating activities was $401.6 million, primarily attributable to repayments and proceeds from investments of $1,339.4 million, an increase in net assets resulting from operations of $170.5 million and other operating activity of $9.8 million, which was partially offset by funding portfolio investments of $1,118.1 million. Cash used in financing activities was $409.2 million during the period due to paydowns on our Revolving Credit Facility of $1,567.8 million, dividends paid of $170.3 million and deferred financing costs of $7.3 million, which was partially offset by borrowings of $1,336.2 million.

As of December 31, 2024, we had $27.3 million in cash and cash equivalents, including $22.4 million of restricted cash. During the year ended December 31, 2024, cash used in operating activities was $45.5 million, primarily attributable to funding portfolio investments of $1,096.1 million, which was partially offset by repayments and proceeds from investments of $863.4 million, an increase in net assets resulting from operations of $186.6 million and other operating activity of $0.7 million. Cash provided by financing activities was $47.6 million during the period due to borrowings of $1,784.9 million and proceeds from issuance of common stock, net of offering and underwriting costs of $93.3 million, which was partially offset by paydowns on our Revolving Credit Facility of $1,653.1 million, dividends paid of $168.7 million and deferred financing costs of $8.8 million.

As of December 31, 2023, we had $25.2 million in cash and cash equivalents, including $24.0 million of restricted cash. During the year ended December 31, 2023, cash used in operating activities was $236.8 million, primarily attributable to funding portfolio investments of $943.5 million and other operating activity of $30.0 million, which was partially offset by repayments and proceeds from investments of $514.7 million and an increase in net assets resulting from operations of $222.0 million. Cash provided by financing activities was $236.3 million during the period due to borrowings of $1,546.2 million and proceeds from issuance of common stock, net of offering and underwriting costs of $89.2 million, which was partially offset by paydowns on our Revolving Credit Facility of $1,233.3 million, dividends paid of $156.4 million and deferred financing costs of $9.4 million.

As of December 31, 2025, we had $16.7 million restricted cash pledged as collateral under our interest rate swap agreements, compared to $22.4 million for the year ended December 31, 2024.

Equity

On March 5, 2024, we issued a total of 4,000,000 shares of common stock at $20.52 per share. Net of underwriting fees and offering costs, we received total cash proceeds of $81.5 million. Subsequent to the offering, the Company issued an additional 600,000

shares on April 1, 2024 pursuant to the overallotment option granted to underwriters and received, net of offering and underwriting fees, additional total cash proceeds of $11.9 million.

We are a party to equity distribution agreements with several banks (the “Equity Distribution Agreements”). The Equity Distribution Agreements provide that we may from time to time issue and sell, by means of “at the market” offerings, up to $100 million of the Company’s common stock. Under the currently effective Equity Distribution Agreements, common stock with an aggregate offering amount of $100 million remained available for issuance as of December 31, 2025.

During the years ended December 31, 2025 and December 31, 2024, we issued 1,043,714 and 1,231,937 shares of our common stock, respectively, to investors who have not opted out of our dividend reinvestment plan for proceeds of $22.5 million and $24.7 million, respectively.

On August 4, 2015, our Board authorized us to acquire up to $50 million in aggregate of our common stock from time to time over an initial six month period, and has continued to authorize the refreshment of the $50 million amount authorized under and extension of the stock repurchase program prior to its expiration since that time, most recently as of November 4, 2025 (expiring on May 31, 2026). Under the program, we may repurchase up to $50 million in the aggregate of our outstanding common stock in the open market, from time to time, at certain thresholds below our net asset value per share, in accordance with the guidelines specified in Rule 10b-18 of the Exchange Act. The amount and timing of stock repurchases under the program may vary depending on market conditions, and no assurance can be given that any particular amount of common stock will be repurchased.

For the years ended December 31, 2025 and December 31, 2024, no shares were repurchased.

Debt

Revolving Credit Facility

On August 23, 2012, we entered into a senior secured revolving credit agreement with Truist Bank (as a successor by merger to SunTrust Bank), as administrative agent, and J.P. Morgan Chase Bank, N.A., as a syndication agent, and certain other lenders (as amended and restated, the “Revolving Credit Facility”).

As of December 31, 2025, aggregate commitments under the Revolving Credit Facility were $1.675 billion. The Revolving Credit Facility includes an uncommitted accordion feature that allows us, under certain circumstances, to increase the size of the Revolving Credit Facility to up to $2.5 billion.

Pursuant to the Fifteenth Amendment dated April 24, 2024, aggregate commitments were increased to $1.7 billion. With respect to $1.505 billion of commitments, the revolving period was extended to April 24, 2028 and the stated maturity was extended to April 24, 2029. For the remaining $195.0 million of commitments, (A) with respect to $25.0 million of commitments, the revolving period ended on February 4, 2025 and the stated maturity is February 4, 2026 and (B) with respect to $170.0 million of commitments, the revolving period ends April 24, 2026 and the stated maturity is April 23, 2027.

Pursuant to the Sixteenth Amendment dated March 4, 2025, with respect to $1.525 billion of commitments, the revolving period, during which period we, subject to certain conditions, may make borrowings under the Revolving Credit Facility, was extended to March 2, 2029 and the stated maturity was extended to March 4, 2030. For the remaining $150.0 million of commitments the revolving period ends April 24, 2026 and the stated maturity is April 23, 2027.

We may borrow amounts in U.S. dollars or certain other permitted currencies. As of December 31, 2025, we had outstanding debt denominated in Australian dollars (AUD) of 3.0 million, British pounds (GBP) of 48.5 million, Canadian dollars (CAD) of 5.0 million, Swedish Krona (SEK) of 218.0 million and Euro (EUR) of 245.9 million on our Revolving Credit Facility, included in the Outstanding Principal amount in the table below. As of December 31, 2024, we had outstanding debt denominated in Australian dollars (AUD) of 63.0 million, British pounds (GBP) of 62.4 million, Canadian dollars (CAD) of 5.0 million, Swedish Krona (SEK) of 80.2 million and Euro (EUR) of 167.2 million on our Revolving Credit Facility, included in the Outstanding Principal amount in the table below.

The Revolving Credit Facility also provides for the issuance of letters of credit up to an aggregate amount of $75 million. As of December 31, 2025 and December 31, 2024 we had $21.7 million and $21.8 million respectively in outstanding letters of credit issued through the Revolving Credit Facility. The amount available for borrowing under the Revolving Credit Facility is reduced by any letters of credit issued through the Revolving Credit Facility.

For the $1.525 billion of commitments, amounts drawn under the Revolving Credit Facility, including amounts drawn in respect of letters of credit, bear interest at either the applicable reference rate plus an applicable credit spread adjustment, plus a margin of either 1.525%, 1.65% or 1.775%, or the base rate plus a margin of either 0.525%, 0.65% or 0.775%, in each case, based on the total amount of the borrowing base relative to the sum of the total commitments (or, if greater, the total exposure) under the Revolving Credit Facility plus certain other designated secured debt. For the remaining $150.0 million of commitments, amounts drawn under the Revolving Credit Facility, including amounts drawn in respect of letters of credit, bear interest at either the applicable reference rate plus an applicable credit spread adjustment, plus a margin of either 1.75% or 1.875% or the base rate plus a margin of either 0.75% or 0.875%, in each case, based on the total amount of the borrowing base relative to the sum of the total commitments (or, if greater, the total exposure) under the Revolving Credit Facility plus certain other designated secured debt. We may elect either the applicable reference rate or base rate of the time of drawdown, and loans may be converted from one rate to another at any time, subject to certain conditions. We also pay a fee of 0.325% on undrawn amounts and, in respect of each undrawn letter of credit, a fee and interest rate equal to the then applicable margin while the letter of credit is outstanding.

The Revolving Credit Facility is guaranteed by Sixth Street SL SPV, LLC, TC Lending, LLC and Sixth Street SL Holding, LLC. The Revolving Credit Facility is secured by a perfected first-priority security interest in substantially all the portfolio investments held by us and each guarantor. Proceeds from borrowings may be used for general corporate purposes, including the funding of portfolio investments.

The Revolving Credit Facility includes customary events of default, as well as customary covenants, including restrictions on certain distributions and financial covenants. In accordance with the terms of the Sixteenth Amendment, the financial covenants require:

an asset coverage ratio of no less than 2 to 1 on the last day of any fiscal quarter;

stockholders’ equity of at least $650 million plus 25% of the net proceeds of the sale of equity interests after April 24, 2024; and

minimum asset coverage ratio of no less than 1.5 to 1 with respect to (i) the consolidated assets of our and our subsidiary’s guarantors (including certain limitations on the contribution of equity in financing subsidiaries) to (ii) the secured debt of our and our subsidiary’s guarantors plus unsecured senior securities of our and our subsidiary guarantors that mature within 90 days of the date of determination (the “Obligor Asset Coverage Ratio”).

The Revolving Credit Facility also contains certain additional concentration limits in connection with the calculation of the borrowing base, based on the Obligor Asset Coverage Ratio.

Net proceeds received from the issuance of the 2030 Notes were used to pay down borrowings on the Revolving Credit Facility.

As of December 31, 2025 and December 31, 2024, the Company was in compliance with the terms of the Revolving Credit Facility.

2023 Notes

In January 2018, we issued $ 150.0 million aggregate principal amount of unsecured notes that matured on January 22, 2023 (the “ 2023 Notes ”). The principal amount of the 2023 Notes was payable at maturity. The 2023 Notes bore interest at a rate of 4.50% per year, payable semi-annually commencing on July 22, 2018, and were redeemable in whole or in part at our option at any time at par plus a “make whole” premium. Total proceeds from the issuance of the 2023 Notes, net of underwriting discounts and offering costs, were $146.9 million. We used the net proceeds of the 2023 Notes to repay outstanding indebtedness under the Revolving Credit Facility. The 2023 Notes matured on January 22, 2023 and were fully repaid in cash. The swap transaction associated with the issuance of the 2023 Notes also matured on January 22, 2023.

2024 Notes

In November 2019, we issued $ 300.0 million aggregate principal amount of unsecured notes that matured on November 1, 2024 (the “ 2024 Notes ” ). The principal amount of the 2024 Notes was payable at maturity. The 2024 Notes bear interest at a rate of 3.875% per year, payable semi-annually commencing on May 1, 2020, and may be redeemed in whole or in part at our option at any time at par plus a “make whole” premium. Total proceeds from the issuance of the 2024 Notes, net of underwriting discounts, offering costs and original issue discount were $292.9 million. We used the net proceeds of the 2024 Notes to repay outstanding indebtedness under the Revolving Credit Facility.

In February 2020, we issued an additional $ 50.0 million aggregate principal amount of unsecured notes that mature on November 1, 2024. The additional 2024 Notes are a further issuance of, fungible with, rank equally in right of payment with and have the same terms (other than the issue date and the public offering price) as the initial issuance of 2024 Notes. Total proceeds from the issuance of the additional 2024 Notes, net of underwriting discounts, offering costs and original issue premium were $50.1 million. We used the net proceeds of the 2024 Notes to repay outstanding indebtedness under the Revolving Credit Facility.

During the year ended December 31, 2020, we repurchased on the open market and extinguished $2.5 million in aggregate principal amount of the 2024 Notes for $2.4 million. These repurchases resulted in a gain on extinguishment of debt of less than $0.1 million. This gain is included in the extinguishment of debt in the accompanying Consolidated Statements of Operations.

The 2024 Notes matured on November 1, 2024 and were fully repaid. The corresponding swap transaction associated with the issuance of the 2024 Notes also matured on November 1, 2024.

2026 Notes

In February 2021, we issued $ 300.0 million aggregate principal amount of unsecured notes that mature on August 1, 2026 (the “ 2026 Notes ” ). The principal amount of the 2026 Notes is payable at maturity. The 2026 Notes bear interest at a rate of 2.50% per year, payable semi-annually commencing on August 1, 2021, and may be redeemed in whole or in part at our option at any time at par plus a “make whole” premium . Total proceeds from the issuance of the 2026 Notes, net of underwriting discounts, offering costs and original issue discount, were $293.7 million. We used the net proceeds of the 2026 Notes to repay outstanding indebtedness under the Revolving Credit Facility.

In connection with the issuance of the 2026 Notes, we entered into an interest rate swap to align the interest rates of our liabilities with our investment portfolio, which consists of predominately floating rate loans. The notional amount of the interest rate swap is $300.0 million, which matures on August 1, 2026, matching the maturity date of the 2026 Notes. As a result of the swap, our effective interest rate on the 2026 Notes is SOFR plus 2.17%. The interest expense related to the 2026 Notes is offset by proceeds received from the interest rate swaps designated as a hedge. The swap adjusted interest expense is included as a component of interest expense on our Consolidated Statements of Operations. As of December 31, 2025 and December 31, 2024, the effective hedge interest rate swaps had a fair value of $(5.8) million and $(17.6) million, respectively, which is offset within interest expense by an equal, but opposite, fair value change for the hedged risk on the 2026 Notes.

2028 Notes

In August 2023, we issued $ 300.0 million aggregate principal amount of unsecured notes that mature on August 14, 2028 ( the “ 2028 Notes ” ).

The interest expense related to the 2028 Notes is offset by proceeds received from the interest rate swaps designated as a hedge. The swap adjusted interest expense is included as a component of interest expense on our Consolidated Statements of Operations. As of December 31, 2025 and December 31, 2024, the effective hedge interest rate swaps had a fair value of $4.5 million and $(1.4) million, respectively, which is offset within interest expense by an equal, but opposite, fair value change for the hedged risk on the 2028 Notes.

2029 Notes

In January 2024, we issued $ 350.0 million aggregate principal amount of unsecured notes that mature on March 1, 2029 ( the “ 2029 Notes ” ).

The notional amount of the interest rate swap is $350.0 million, which matures on March 1, 2029, matching the maturity date of the 2029 Notes. As a result of the swap, our effective interest rate on the 2029 Notes is SOFR plus 2.44%. The interest expense related to the 2029 Notes is offset by proceeds received from the interest rate swaps designated as a hedge. The swap adjusted interest expense is included as a component of interest expense on our Consolidated Statements of Operations. As of December 31, 2025 and December 31, 2024 the effective hedge interest rate swaps had a fair value of $3.3 million and $(5.2) million, respectively, which is offset within interest expense by an equal, but opposite, fair value change for the hedged risk on the 2029 Notes.

Off-Balance Sheet Arrangements

Portfolio Company Commitments

From time to time, we may enter into commitments to fund investments. We incorporate these commitments into our assessment of our liquidity position. Our senior secured revolving loan commitments are generally available on a borrower’s demand and may remain outstanding until the maturity date of the applicable loan. Our senior secured delayed draw term loan commitments are generally available on a borrower’s demand and, once drawn, generally have the same remaining term as the associated loan agreement. Undrawn senior secured delayed draw term loan commitments generally have a shorter availability period than the term of the associated loan agreement. As of December 31, 2025 and December 31, 2024, we had the following commitments to fund investments in current portfolio companies:

Total Portfolio Company Commitments (1)(2)

Represents the full amount of our commitments to fund investments on such date. Commitments may be subject to limitations on borrowings set forth in the agreements between us and the applicable portfolio company. As a result, portfolio companies may not be eligible to borrow the full commitment amount on such date.

Our estimate of the fair value of the current investments in these portfolio companies includes an analysis of the fair value of any unfunded commitments.

Other Commitments and Contingencies

As of December 31, 2025 and December 31, 2024, we did not have any unfunded commitments to fund investments to new borrowers that were not current portfolio companies as of such date.

From time to time, we may become a party to certain legal proceedings incidental to the normal course of our business. As of December 31, 2025 and December 31, 2024, management is not aware of any material pending or threatened litigation that would require accounting recognition or financial statement disclosure.

We have certain contracts under which we have material future commitments. Under the Investment Advisory Agreement, our Adviser provides us with investment advisory and management services. For these services, we pay the Management Fee and the Incentive Fee.

Under the Administration Agreement, our Adviser furnishes us with office facilities and equipment, provides us clerical, bookkeeping and record keeping services at such facilities and provides us with other administrative services necessary to conduct our day-to-day operations. We reimburse our Adviser for the allocable portion (subject to the review and approval of our Board) of expenses incurred by it in performing its obligations under the Administration Agreement, the fees and expenses associated with performing compliance functions and our allocable portion of the compensation of our Chief Compliance Officer, Chief Financial

Officer and other professionals who spend time on those related activities (based on a percentage of time those individuals devote, on an estimated basis, to our business and affairs). Our Adviser also offers on our behalf significant managerial assistance to those portfolio companies to which we are required to offer to provide such assistance.

In addition to the contractual payment obligations in the tables above, we also have commitments to fund investments and to pledge assets as collateral under the terms of our derivatives agreements.

Distributions

We have elected and qualified to be treated for U.S. federal income tax purposes as a RIC under subchapter M of the Code. To maintain our RIC status, we must distribute (or be treated as distributing) in each taxable year dividends for tax purposes equal to at least 90 percent of the sum of our:

investment company taxable income (which is generally our ordinary income plus the excess of realized net short-term capital gains over realized net long-term capital losses), determined without regard to the deduction for dividends paid, for such taxable year; and

net tax-exempt interest income (which is the excess of our gross tax exempt interest income over certain disallowed deductions) for such taxable year.

As a RIC, we (but not our stockholders) generally will not be subject to U.S. federal income tax on investment company taxable income and net capital gains that we distribute to our stockholders.

We intend to distribute annually all or substantially all of such income. To the extent that we retain our net capital gains or any investment company taxable income, we generally will be subject to corporate-level U.S. federal income tax. We may choose to retain our net capital gains or any investment company taxable income, and pay the U.S. federal excise tax described below.

Amounts not distributed on a timely basis in accordance with a calendar year distribution requirement are subject to a nondeductible 4% U.S. federal excise tax payable by us. To avoid this tax, we must distribute (or be treated as distributing) during each calendar year an amount at least equal to the sum of:

98% of our net ordinary income excluding certain ordinary gains or losses for that calendar year;

98.2% of our capital gain net income, adjusted for certain ordinary gains and losses, recognized for the twelve-month period ending on October 31 of that calendar year; and

100% of any income or gains recognized, but not distributed, in preceding years.

While we intend to distribute any income and capital gains in the manner necessary to minimize imposition of the 4% U.S. federal excise tax, sufficient amounts of our taxable income and capital gains may not be distributed to avoid entirely the imposition of this tax. In that event, we will be liable for this tax only on the amount by which we do not meet the foregoing distribution requirement.

We intend to pay quarterly dividends to our stockholders out of assets legally available for distribution. All dividends will be paid at the discretion of our Board and will depend on our earnings, financial condition, maintenance of our RIC status, compliance with applicable BDC regulations and such other factors as our Board may deem relevant from time to time.

To the extent our current taxable earnings for a year fall below the total amount of our distributions for that year, a portion of those distributions may be deemed a return of capital to our stockholders for U.S. federal income tax purposes. Thus, the source of a distribution to our stockholders may be the original capital invested by the stockholder rather than our income or gains. Stockholders should read any written disclosure carefully and should not assume that the source of any distribution is our ordinary income or gains.

We have adopted an “opt out” dividend reinvestment plan for our common stockholders. As a result, if we declare a cash dividend or other distribution, each stockholder that has not “opted out” of our dividend reinvestment plan will have their dividends or distributions automatically reinvested in additional shares of our common stock rather than receiving cash dividends. Stockholders who receive distributions in the form of shares of common stock will be subject to the same U.S. federal, state and local tax consequences as if they received cash distributions.

Related-Party Transactions

We have entered into a number of business relationships with affiliated or related parties, including the following:

the Investment Advisory Agreement;

the Administration Agreement; and

an ongoing agreement with an affiliate of TPG Global, LLC governing, inter alia, the parties’ respective ownership of and rights to use the “Sixth Street” and “TPG” trademarks and certain variations thereof.

Critical Accounting Estimates

The preparation of our consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses. Changes in the economic environment, financial markets, and any other parameters used in determining such estimates could cause actual results to differ. Our critical accounting policies, including those relating to the valuation of our investment portfolio, are described below. The critical accounting policies should be read in connection with our risk factors as disclosed in “ITEM 1A. RISK FACTORS.”

Investments at Fair Value

Loan originations are recorded on the date of the binding commitment, which is generally the funding date. Investment transactions purchased through the secondary markets are recorded on the trade date. Realized gains or losses are measured by the difference between the net proceeds received (excluding prepayment fees, if any) and the amortized cost basis of the investment without regard to unrealized gains or losses previously recognized, and include investments charged off during the period, net of recoveries. The net change in unrealized gains or losses primarily reflects the change in investment values and also includes the reversal of previously recorded unrealized gains or losses with respect to investments realized during the period.

Investments for which market quotations are readily available are typically valued at those market quotations. To validate market quotations, we utilize a number of factors to determine if the quotations are representative of fair value, including the source and number of the quotations. Debt and equity securities that are not publicly traded or whose market prices are not readily available, as is the case for substantially all of our investments, are valued at fair value as determined in good faith by our Board, based on, among other things, the input of the Adviser, our Audit Committee and independent third-party valuation firms engaged at the direction of the Board.

As part of the valuation process, the Board takes into account relevant factors in determining the fair value of our investments, including and in combination of:

the estimated enterprise value of a portfolio company (that is, the total value of the portfolio company’s net debt and equity);

the nature and realizable value of any collateral;

the portfolio company’s ability to make payments based on its earnings and cash flow;

the markets in which the portfolio company does business;

a comparison of the portfolio company’s securities to any similar publicly traded securities; and

overall changes in the interest rate environment and the credit markets that may affect the price at which similar investments may be made in the future.

When an external event, such as a purchase transaction, public offering or subsequent equity sale occurs, the Board considers whether the pricing indicated by the external event corroborates our valuation.

The Board undertakes a multi-step valuation process, which includes, among other procedures, the following:

The valuation process begins with each investment being initially valued by the investment professionals responsible for the portfolio investment in conjunction with the portfolio management team.

The Adviser’s management reviews the preliminary valuations with the investment professionals. Agreed-upon valuation recommendations are presented to the Audit Committee.

The Audit Committee reviews the valuations presented and recommends values for each investment to the Board.

The Board reviews the recommended valuations and determines the fair value of each investment; valuations that are not based on readily available market quotations are valued in good faith based on, among other things, the input of the Adviser, Audit Committee and, where applicable, other third parties, including independent third party valuation firms engaged at the direction of the Board.

We conduct this valuation process on a quarterly basis.

The Board has engaged independent third-party valuation firms to perform certain limited procedures that the Board has identified and requested them to perform in connection with the valuation process of investments for which no market quotations are readily available. At December 31, 2025, the independent third-party valuation firms performed their procedures over substantially all of our investments. Upon completion of such limited procedures, the third-party valuation firms determined that the fair value, as determined by the Board, of those investments subjected to their limited procedures, appeared reasonable.

We apply Financial Accounting Standards Board Accounting Standards Codification Topic 820, Fair Value Measurement (“ASC Topic 820”), as amended, which establishes a framework for measuring fair value in accordance with U.S. GAAP and required disclosures of fair value measurements. ASC Topic 820 determines fair value to be the price that would be received for an investment in a current sale, which assumes an orderly transaction between market participants on the measurement date. Market participants are defined as buyers and sellers in the principal or most advantageous market (which may be a hypothetical market) that are independent, knowledgeable, and willing and able to transact. In accordance with ASC Topic 820, we consider our principal market to be the market that has the greatest volume and level of activity. ASC Topic 820 specifies a fair value hierarchy that prioritizes and ranks the level of observability of inputs used in determination of fair value. In accordance with ASC Topic 820, these levels are summarized below:

Level 1—Valuations based on quoted prices in active markets for identical assets or liabilities that we have the ability to access.

Level 2—Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3—Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

Transfers between levels, if any, are recognized at the beginning of the quarter in which the transfers occur. In addition to using the above inputs in investment valuations, we apply the valuation policy approved by our Board that is consistent with ASC Topic 820. Consistent with the valuation policy, we evaluate the source of inputs, including any markets in which our investments are trading (or any markets in which securities with similar attributes are trading), in determining fair value. When a security is valued based on prices provided by reputable dealers or pricing services (that is, broker quotes), we subject those prices to various additional criteria in making the determination as to whether a particular investment would qualify for treatment as a Level 2 or Level 3 investment. For example, we review pricing and methodologies provided by dealers or pricing services in order to determine if observable market information is being used, versus unobservable inputs. Some additional factors considered include the number of prices obtained, as well as an assessment as to their quality, such as the depth of the relevant market relative to the size of the Company’s position.

Our accounting policy on the fair value of our investments is critical because the determination of fair value involves subjective judgments and estimates. Accordingly, the notes to our consolidated financial statements express the uncertainty with respect to the possible effect of these valuations, and any change in these valuations, on the consolidated financial statements.

See Note 6 to our consolidated financial statements included in this Form 10-K for more information on the fair value of our investments.

Interest and Dividend Income Recognition

Interest income is recorded on an accrual basis and includes the amortization of discounts and premiums. Discounts and premiums to par value on securities purchased or originated are amortized into interest income over the contractual life of the respective security

using the effective interest method. The amortized cost of investments represents the original cost adjusted for the amortization of discounts and premiums, if any.

Unless providing services in connection with an investment, such as syndication, structuring or diligence, all or a portion of any loan fees received by us will be deferred and amortized over the investment’s life using the effective interest method.

Loans are generally placed on non-accrual status when principal or interest payments are past due 30 days or more or when management has reasonable doubt that the borrower will pay principal or interest in full. Accrued and unpaid interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. Non-accrual loans are restored to accrual status when past due principal and interest has been paid and, in management’s judgment, the borrower is likely to make principal and interest payments in the future. Management may determine to not place a loan on non-accrual status if, notwithstanding any failure to pay, the loan has sufficient collateral value and is in the process of collection.

Dividend income on preferred equity securities is recorded on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies.

Our accounting policy on interest and dividend income recognition is critical because it involves the primary source of our revenue and accordingly is significant to the financial results as disclosed in our consolidated financial statements.

U.S. Federal Income Taxes

We have elected to be treated as a BDC under the 1940 Act. We also have elected to be treated as a RIC under the Code. So long as we maintain our status as a RIC, we will generally not pay corporate-level U.S. federal income or excise taxes on any ordinary income or capital gains that we distribute at least annually to our stockholders as dividends. As a result, any tax liability related to income earned and distributed by us represents obligations of our stockholders and will not be reflected in our consolidated financial statements.

We evaluate tax positions taken or expected to be taken in the course of preparing our financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are reversed and recorded as a tax benefit or expense in the current year. All penalties and interest associated with income taxes are included in income tax expense. Conclusions regarding tax positions are subject to review and may be adjusted at a later date based on factors including, but not limited to, on-going analyses of tax laws, regulations and interpretations thereof. As of December 31, 2025, we did not have any uncertain tax positions that met the recognition or measurement criteria, nor did we have any unrecognized tax benefits. Our 2024, 2023 and 2022 tax year returns remain subject to examination by the relevant federal, state, and local tax authorities.

Our accounting policy on income taxes is critical because if we are unable to maintain our status as a RIC, we would be required to record a provision for corporate-level U.S. federal income taxes which may be significant to our financial results.

I TEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are subject to financial market risks, including valuation risk, interest rate risk and currency risk.

Valuation Risk

We have invested, and plan to continue to invest, primarily in illiquid debt and equity securities of private companies. Most of our investments will not have a readily available market price, and we value these investments at fair value as determined in good faith by our Board in accordance with our valuation policy. There is no single standard for determining fair value. As a result, determining fair value requires that judgment be applied to the specific facts and circumstances of each portfolio investment while employing a consistently applied valuation process for the types of investments we make. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we may realize amounts that are different from the amounts presented and such differences could be material.

Interest Rate Risk

Interest rate sensitivity refers to the change in earnings that may result from changes in the level of interest rates. We also fund portions of our investments with borrowings. Our net investment income is affected by the difference between the rate at which we invest and the rate at which we borrow. Accordingly, we cannot assure you that a significant change in market interest rates will not have a material adverse effect on our net investment income.

We regularly measure our exposure to interest rate risk. We assess interest rate risk and manage our interest rate exposure on an ongoing basis by comparing our interest rate-sensitive assets to our interest rate-sensitive liabilities. Based on that review, we determine whether or not any hedging transactions are necessary to mitigate exposure to changes in interest rates.

As of December 31, 2025, 96.3% of our debt investments based on fair value in our portfolio bore interest at floating rates, with 100.0% of these subject to interest rate floors. Our credit facilities also bear interest at floating rates, and in connection with our 2026 Notes, 2028 Notes, 2029 Notes and 2030 Notes, which bear interest at fixed rates, we entered into fixed-to-floating interest rate swaps in order to align the interest rates of our liabilities with our investment portfolio.

Assuming that our Consolidated Balance Sheet as of December 31, 2025 were to remain constant and that we took no actions to alter our existing interest rate sensitivity, the following table shows the annualized impact of hypothetical base rate changes in interest rates (considering interest rate floors for floating rate instruments):

($ in millions)

Basis Point Change

Interest Expense

Net Interest Income

Up 300 basis points

Up 200 basis points

Up 100 basis points

Down 25 basis points

Down 50 basis points

Down 75 basis points

Down 100 basis points

Although we believe that this analysis is indicative of our existing sensitivity to interest rate changes, it does not adjust for changes in the credit market, credit quality, the size and composition of the assets in our portfolio and other business developments that could affect our net income. Accordingly, we cannot assure you that actual results would not differ materially from the analysis above.

We may in the future hedge against interest rate fluctuations by using hedging instruments such as additional interest rate swaps, futures, options and forward contracts. While hedging activities may mitigate our exposure to adverse fluctuations in interest rates, certain hedging transactions that we may enter into in the future, such as interest rate swap agreements, may also limit our ability to participate in the benefits of changes in interest rates with respect to our portfolio investments.

Currency Risk

From time to time, we may make investments that are denominated in a foreign currency. These investments are translated into U.S. dollars at each balance sheet date, exposing us to movements in foreign exchange rates. We may employ hedging techniques to minimize these risks, but we cannot assure you that such strategies will be effective or without risk to us. We may seek to utilize instruments such as, but not limited to, forward contracts to seek to hedge against fluctuations in the relative values of our portfolio positions from changes in currency exchange rates. We also have the ability to borrow in certain foreign currencies under our Revolving Credit Facility. Instead of entering into a foreign exchange forward contract in connection with loans or other investments we have made that are denominated in a foreign currency, we may borrow in that currency to establish a natural hedge against our loan or investment. To the extent the loan or investment is based on a floating rate other than a rate under which we can borrow under our Revolving Credit Facility, we may seek to utilize interest rate derivatives to hedge our exposure to changes in the associated rate.

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheets of Sixth Street Specialty Lending, Inc. 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 years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements). We also have audited the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in the Internal Control – Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission.

In our opinion, the consolidated financial statements referred to above 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 and its cash flows for each of the years in the three-year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective 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.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, 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 consolidated financial statements and an opinion on the Company’s internal control over financial reporting 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 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 audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements 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. Such procedures also included confirmation of securities owned as of December 31, 2025 and 2024, by correspondence with custodians, agents, the underlying investees or by other appropriate auditing procedures. 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 audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated 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 consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated 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.

Assessment of the fair value of investments

As discussed in Notes 2, 4, and 6 to the consolidated financial statements, the Company classified $3.18 billion of its debt and equity investments as Level 3 in the fair value hierarchy as of December 31, 2025, as the fair value of such investments was measured using unobservable inputs. The Company typically determines the fair value of performing debt investments utilizing a yield analysis where a price is ascribed for each investment based upon an assessment of market yields for similar investments and, for its equity investments, multiples of similar companies’ revenues, earnings before income taxes, depreciation and amortization or some combination thereof and comparable market transactions.

We identified the assessment of the fair value of certain Level 3 debt and equity investments as a critical audit matter because evaluating the assumptions used to measure fair value involved subjective auditor judgment and changes in these assumptions could have had a significant impact on the investments’ estimated fair value. Specifically, the assumptions related to market yields for investments with similar terms and risks used in yield analyses, comparable financial performance multiples, and expected lives used in discounted cash flow analyses required subjective auditor judgment.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s investment valuation process, including controls related to the determination of the market yields, financial performance multiples, and expected lives used to estimate the fair value of investments. We assessed the Company’s market yield assumptions used to measure the fair value of its Level 3 investments by comparing such yields to third-party market and industry data for a selection of investments. We involved valuation professionals with specialized skills and knowledge who, for a selection of the Company’s investments, evaluated the Company’s estimate of fair value by developing an independent estimate of fair value through the use of relevant market information to develop a range of comparable financial performance multiples and market yield assumptions. We evaluated the Company’s ability to estimate fair value by comparing prior period values to prices of transactions occurring subsequent to the prior period valuation date.

Instrument is used in a hedge accounting relationship. The associated change in fair value is recorded along with the change in fair value of the hedged item within interest expense.

Certain portfolio company investments are subject to contractual restrictions on sales.

The amortized cost represents the original cost adjusted for the amortization of discounts and premiums, as applicable, on debt investments using the effective interest method.

Investment contains a variable rate structure, subject to an interest rate floor. Variable rate investments bear interest at a rate that may be determined by reference to either Euro Interbank Offer Rate (“Euribor” or “E”), Sterling Overnight Index Average (“SONIA”), Secured Overnight Financing Rate (“SOFR”) which may also contain a credit spread adjustment depending on the tenor election, Stockholm Interbank Offered Rate (“STIBOR”), Norwegian Interbank Offered Rate (“NIBOR” or “N”) or an alternate base rate (which can include the Federal Funds Effective Rate or the Prime Rate or “P”), all of which include an available tenor, selected at the borrower’s option, which reset periodically based on the terms of the credit agreement. For investments with multiple interest rate contracts, the interest rate shown is the weighted average interest rate in effect at December 31, 2025 .

This portfolio company is not a qualifying asset under Section 55(a) of the Investment Company Act of 1940, as amended (the “1940 Act”). Under the 1940 Act, the Company may not acquire any non-qualifying asset unless, at the time such acquisition is made, qualifying assets represent at least 70 % of total assets. Non-qualifying assets represented 19.9 % of total assets as of December 31, 2025 .

In addition to the interest earned based on the stated interest rate of this investment, which is the amount reflected in this schedule, the Company may be entitled to receive additional interest as a result of an arrangement with other members in the syndicate to the extent an investment has been allocated to “first out” and “last out” tranches, whereby the “first out” tranche will have priority as to the “last out” tranche with respect to payments of principal, interest and any amounts due thereunder and the Company holds the “last out” tranche.

Under the 1940 Act, the Company is deemed to be both an “Affiliated Person” of and “Control,” as such terms are defined in the 1940 Act, this portfolio company, as the Company owns more than 25 % of the portfolio company’s outstanding voting securities or has the power to exercise control over management or policies of such portfolio company (including through a management agreement). Transactions during the year ended December 31, 2025 in which the issuer was an Affiliated Person of and was deemed to Control a portfolio company are as follows:

Contains a variable rate structure. Bears interest at a rate determined by SOFR.

Instrument is used in a hedge accounting relationship. The associated change in fair value is recorded along with the change in fair value of the hedged item within interest expense.

Certain portfolio company investments are subject to contractual restrictions on sales.

The amortized cost represents the original cost adjusted for the amortization of discounts and premiums, as applicable, on debt investments using the effective interest method.

Investment contains a variable rate structure, subject to an interest rate floor. Variable rate investments bear interest at a rate that may be determined by reference to either Euro Interbank Offer Rate (“Euribor” or “E”), Sterling Overnight Index Average (“SONIA”), Secured Overnight Financing Rate (“SOFR”) which may also contain a credit spread adjustment depending on the tenor election, Bank Bill Swap Bid Rate (“BBSY” or “B”), Stockholm Interbank Offered Rate (“STIBOR”), Norwegian Interbank Offered Rate (“NIBOR” or “N”), or an alternate base rate (which can include the Federal Funds Effective Rate or the Prime Rate or “P”), all of which include an available tenor, selected at the borrower’s option, which reset periodically based on the terms of the credit agreement. For investments with multiple interest rate contracts, the interest rate shown is the weighted average interest rate in effect at December 31, 2024.

This portfolio company is not a qualifying asset under Section 55(a) of the Investment Company Act of 1940, as amended (the “1940 Act”). Under the 1940 Act, the Company may not acquire any non-qualifying asset unless, at the time such acquisition is made, qualifying assets represent at least 70 % of total assets. Non-qualifying assets represented 16.5 % of total assets as of December 31, 2024.

In addition to the interest earned based on the stated interest rate of this investment, which is the amount reflected in this schedule, the Company may be entitled to receive additional interest as a result of an arrangement with other members in the syndicate to the extent an investment has been allocated to “first out” and “last out” tranches, whereby the “first out” tranche will have priority as to the “last out” tranche with respect to payments of principal, interest and any amounts due thereunder and the Company holds the “last out” tranche.

Under the 1940 Act, the Company is deemed to be both an “Affiliated Person” of and “Control,” as such terms are defined in the 1940 Act, this portfolio company, as the Company owns more than 25 % of the portfolio company’s outstanding voting securities or has the power to exercise control over management or policies of such portfolio company (including through a management agreement). Transactions during the year ended December 31, 2024 in which the issuer was an Affiliated Person of and was deemed to Control a portfolio company are as follows:

Gross additions include increases in the cost basis of investments resulting from new investments, payment-in-kind interest or dividends, the amortization of any unearned income or discounts on debt investments, as applicable.

Gross reductions include decreases in the cost basis of investments resulting from principal collections related to investment repayments or sales, and the amortization of any premiums on debt investments, as applicable. When an investment is placed on non-accrual status, any cash flows received by the Company are applied to the outstanding principal balance.

As of December 31, 2024, the estimated cost basis of investments for U.S. federal tax purposes was $ 3,535,963 resulting in estimated gross unrealized gains and losses of $ 207,435 and $ 216,975 , respectively.

In accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 820, Fair Value Measurements (“ASC Topic 820”), unless otherwise indicated, the fair values of all investments were determined using

significant unobservable inputs and are considered Level 3 investments. See Note 6 for further information related to investments at fair value.

This investment is valued using observable inputs and is considered a Level 2 investment. See Note 6 for further information related to investments at fair value.

This investment is valued using observable inputs and is considered a Level 1 investment. See Note 6 for further information related to investments at fair value.

This investment is non-income producing.

All or a portion of this security was acquired in a transaction exempt from registration under the Securities Act of 1933, and may be deemed to be “restricted securities” under the Securities Act. As of December 31, 2024, the aggregate fair value of these securities is $ 12,926 , or 0.8 % of the Company’s net assets.

Ownership of equity investments may occur through a holding company or partnership.

Investment is on non-accrual status as of December 31, 2024.

In addition to the principal amount outstanding and accrued interest owed on this investment, the Company is entitled to a separate Make-Whole Amount (the “Make-Whole”) of $ 13.7 million. The Make-Whole is a contractual obligation of the borrower and accrues interest on the balance outstanding. The Make-Whole is included on the Company’s Consolidated Balance Sheet within other assets, net of any valuation allowance. Given uncertainty relating to collectability of the Make-Whole, the Company has applied a full valuation allowance against the amount of the Make-Whole balance outstanding.

1. Organization and Basis of Presentation

Organization

Sixth Street Specialty Lending, Inc. (the “Company”) is a Delaware corporation formed on July 21, 2010. The Company was formed primarily to lend to, and selectively invest in, middle-market companies in the United States. The Company has elected to be regulated as a business development company (“BDC”) under the 1940 Act. In addition, for tax purposes, the Company has elected to be treated as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). The Company is managed by Sixth Street Specialty Lending Advisers, LLC (the “Adviser”).

On June 1, 2011, the Company formed a wholly-owned subsidiary, TC Lending, LLC, a Delaware limited liability company.

On March 22, 2012, the Company formed a wholly-owned subsidiary, Sixth Street SL SPV, LLC, a Delaware limited liability company.

On May 19, 2014, the Company formed a wholly-owned subsidiary, Sixth Street SL Holding, LLC, a Delaware limited liability company.

On December 9, 2020, the Company formed a wholly-owned subsidiary, Sixth Street Specialty Lending Sub, LLC, a Cayman Islands limited liability company.

On March 21, 2014, the Company completed its initial public offering (“IPO”) and the Company’s shares began trading on the New York Stock Exchange (“NYSE”) under the symbol “TSLX.”

On December 23, 2025, affiliates of Sixth Street, including the Company, and affiliates of Carlyle Group Inc. (“Carlyle”) entered into an amended and restated limited liability company agreement, as amended from time to time (the “Limited Liability Company Agreement”) to co-manage Structured Credit Partners JV, LLC (“SCP”), a joint venture focused on investing in broadly syndicated first lien senior secured loans, financed with long-term, non-mark-to-market, and predominantly investment grade rated CLO debt. The Company has 25.0 % voting ownership in SCP and has commitments to fund, from time to time, capital of up to $ 200.0 million. Refer to Note 6, Fair Value of Financial Instruments, to these consolidated financial statements for further details.

Basis of Presentation

The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), and include the accounts of the Company and its subsidiaries. In the opinion of management, all adjustments considered necessary for the fair presentation of the consolidated financial statements for the periods presented have been included. All intercompany balances and transactions have been eliminated in consolidation.

The Company is an investment company and, therefore, applies the specialized accounting and reporting guidance in Accounting Standards Codification (“ASC”) Topic 946, Financial Services – Investment Companies.

Fiscal Year End

The Company’s fiscal year ends on December 31.

2. Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Actual amounts could differ from those estimates and such differences could be material.

Cash and Cash Equivalents

Cash and cash equivalents may consist of demand deposits, highly liquid investments (e.g., money market funds, U.S. Treasury notes, and similar type instruments) with original maturities of three months or less, and restricted cash pledged as collateral for certain centrally cleared derivative instruments. Cash and cash equivalents denominated in U.S. dollars are carried at cost, which approximates fair value. The Company deposits its cash and cash equivalents with highly-rated banking corporations and, at times, cash deposits may exceed the insured limits under applicable law.

Investments at Fair Value

Loan originations are recorded on the date of the binding commitment, which is generally the funding date. Investment transactions purchased through the secondary markets are recorded on the trade date. Realized gains or losses are measured by the difference between the net proceeds received (excluding prepayment fees, if any) and the amortized cost basis of the investment without regard to unrealized gains or losses previously recognized, and include investments charged off during the period, net of recoveries. The net change in unrealized gains or losses primarily reflects the change in investment values and also includes the reversal of previously recorded unrealized gains or losses with respect to investments realized during the period.

Investments for which market quotations are readily available are typically valued at those market quotations. To validate market quotations, the Company utilizes a number of factors to determine if the quotations are representative of fair value, including the source and number of the quotations. Debt and equity securities that are not publicly traded or whose market prices are not readily available, as is the case for substantially all of our investments, are valued at fair value as determined in good faith by the Company’s Board of Directors (the “Board”), based on, among other things, the input of the Adviser, the Company’s Audit Committee and independent third-party valuation firms engaged at the direction of the Board.

As part of the valuation process, the Board takes into account relevant factors in determining the fair value of our investments, including and in combination of: the estimated enterprise value of a portfolio company (that is, the total value of the portfolio company’s net debt and equity), the nature and realizable value of any collateral, the portfolio company’s ability to make payments based on its earnings and cash flow, the markets in which the portfolio company does business, a comparison of the portfolio company’s securities to any similar publicly traded securities, and overall changes in the interest rate environment and the credit markets that may affect the price at which similar investments may be made in the future. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, the Board considers whether the pricing indicated by the external event corroborates its valuation.

The Board undertakes a multi-step valuation process, which includes, among other procedures, the following:

The valuation process begins with each investment being initially valued by the investment professionals responsible for the portfolio investment in conjunction with the portfolio management team.

The Adviser’s management reviews the preliminary valuations with the investment professionals. Agreed upon valuation recommendations are presented to the Audit Committee.

The Audit Committee reviews the valuations presented and recommends values for each investment to the Board.

The Board reviews the recommended valuations and determines the fair value of each investment; valuations that are not based on readily available market quotations are valued in good faith based on, among other things, the input of the Adviser, Audit Committee and, where applicable, other third parties including independent third-party valuation firms engaged at the direction of the Board.

The Company conducts this valuation process on a quarterly basis.

The Board has engaged independent third-party valuation firms to perform certain limited procedures that the Board has identified and requested them to perform in connection with the valuation process of investments for which no market quotations are readily available. At December 31, 2025, the independent third-party valuation firms performed their procedures over substantially all of the Company’s investments. Upon completion of such limited procedures, the third-party valuation firms concluded that the fair value, as determined by the Board, of those investments subjected to their limited procedures, appeared reasonable.

The Company applies Financial Accounting Standards Board Accounting Standards Codification Topic 820, Fair Value Measurement (“ASC Topic 820”), as amended, which establishes a framework for measuring fair value in accordance with U.S. GAAP and required disclosures of fair value measurements. ASC Topic 820 determines fair value to be the price that would be received for an investment in a current sale, which assumes an orderly transaction between market participants on the measurement date. Market participants are defined as buyers and sellers in the principal or most advantageous market (which may be a hypothetical market) that are independent, knowledgeable, and willing and able to transact. In accordance with ASC Topic 820, the Company considers its principal market to be the market that has the greatest volume and level of activity. ASC Topic 820 specifies a fair value

hierarchy that prioritizes and ranks the level of observability of inputs used in determination of fair value. In accordance with ASC Topic 820, these levels are summarized below:

Level 1—Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.

Level 2—Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3—Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

Transfers between levels, if any, are recognized at the beginning of the quarter in which the transfers occur. In addition to using the above inputs in investment valuations, the Company applies the valuation policy approved by its Board that is consistent with ASC Topic 820. Consistent with the valuation policy, the Company evaluates the source of inputs, including any markets in which its investments are trading (or any markets in which securities with similar attributes are trading), in determining fair value. When a security is valued based on prices provided by reputable dealers or pricing services (that is, broker quotes), the Company subjects those prices to various additional criteria in making the determination as to whether a particular investment would qualify for treatment as a Level 2 or Level 3 investment. For example, the Company reviews pricing provided by dealers or pricing services in order to determine if observable market information is being used, versus unobservable inputs. Some additional factors considered include the number of prices obtained as well as an assessment as to their quality, such as the depth of the relevant market relative to the size of the Company’s position.

Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the Company’s investments may fluctuate from period to period. Additionally, the fair value of such investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that may ultimately be realized. Further, such investments are generally less liquid than publicly traded securities and may be subject to contractual and other restrictions on resale. If the Company were required to liquidate a portfolio investment in a forced or liquidation sale, it could realize amounts that are different from the amounts presented and such differences could be material.

In addition, changes in the market environment including the impact of changes in broader market indices and credit spreads and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the unrealized gains or losses reflected herein.

Financial and Derivative Instruments

The Company recognizes all derivative instruments as assets or liabilities at fair value in its consolidated financial statements, pursuant to ASC Topic 815 Derivatives and Hedging, further clarified by the FASB’s issuance of the Accounting Standards Update (“ASU”) No. 2017-12, Derivatives and Hedging, which was adopted in 2019 by the Company. For all derivative instruments designated in a hedge accounting relationship, the entire change in the fair value of the hedging instrument shall be recorded in the same line item of the Consolidated Statements of Operations as the hedged item. The Company uses certain interest rate swaps as derivative instruments to hedge the Company’s fixed rate debt, and therefore both the periodic payment and the change in fair value for the effective hedge, if applicable, will be recognized as components of interest expense in the Consolidated Statements of Operations. For derivative contracts entered into by the Company that are not designated in a hedge accounting relationship, the Company presents changes in the fair value through current period earnings.

In the normal course of business, the Company has commitments and risks resulting from its investment transactions, which may include those involving derivative instruments. Derivative instruments are measured in terms of the notional contract amount and derive their value based upon one or more underlying instruments. While the notional amount gives some indication of the Company’s derivative activity, it generally is not exchanged, but is only used as the basis on which interest and other payments are exchanged. Derivative instruments are subject to various risks similar to non-derivative instruments including market, credit, liquidity, and operational risks. The Company manages these risks on an aggregate basis as part of its risk management process.

Derivatives, including the Company’s interest rate swaps, for which broker quotes are available are typically valued at those broker quotes.

Offsetting Assets and Liabilities

Foreign currency forward contract and interest rate swap receivables or payables pending settlement are offset, and the net amount is included with receivable or payable for foreign currency forward contracts or interest rate swaps in the Consolidated Balance Sheets when, and only when, they are with the same counterparty, the Company has the legal right to offset the recognized amounts, and it intends to either settle on a net basis or realize the asset and settle the liability simultaneously.

Foreign Currency

Foreign currency amounts are translated into U.S. dollars on the following basis:

cash and cash equivalents, market value of investments, outstanding debt on revolving credit facilities, other assets and liabilities: at the spot exchange rate on the last business day of the period; and

purchases and sales of investments, borrowings and repayments of such borrowings, income and expenses: at the rates of exchange prevailing on the respective dates of such transactions.

Although net assets and fair values are presented based on the applicable foreign exchange rates described above, the Company does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in fair values of investments held. Such fluctuations are included with the net realized and unrealized gain or loss from investments. The Company’s current approach to hedging the foreign currency exposure in its non-U.S. dollar denominated investments is primarily to borrow the par amount in local currency under the Company’s Revolving Credit Facility to fund these investments. Fluctuations arising from the translation of foreign currency borrowings are included with the net change in unrealized gains (losses) on translation of assets and liabilities in foreign currencies on the Consolidated Statements of Operations.

Investments denominated in foreign currencies and foreign currency transactions may involve certain considerations and risks not typically associated with those of domestic origin, including unanticipated movements in the value of the foreign currency relative to the U.S. dollar.

Equity Offering Expenses

The Company records expenses related to equity offerings as a reduction of capital upon completion of an offering of registered securities. The costs associated with renewals of the Company’s shelf registration statement are expensed as incurred.

Debt Issuance Costs

The Company records origination and other expenses related to its debt obligations as deferred financing costs, which are presented as a direct deduction from the carrying value of the related debt liability. These expenses are deferred and amortized using the effective interest method, or straight-line method, over the stated maturity of the debt obligation.

Interest and Dividend Income Recognition

Interest income is recorded on an accrual basis and includes the amortization of discounts and premiums. Discounts and premiums to par value on securities purchased or originated are amortized into interest income over the contractual life of the respective security using the effective interest method. The amortized cost of investments represents the original cost adjusted for the amortization of discounts and premiums, if any.

Unless providing services in connection with an investment, such as syndication, structuring or diligence, all or a portion of any loan fees received by the Company will be deferred and amortized over the investment’s life using the effective interest method.

Loans are generally placed on non-accrual status when principal or interest payments are past due 30 days or more or when management has reasonable doubt that the borrower will pay principal or interest in full. Accrued and unpaid interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding collectability. Non-accrual loans are restored to accrual status when past due principal and interest has been paid and, in management’s judgment, the borrower is likely to make principal and interest payments in the future. Management may determine to not place a loan on non-accrual status if, notwithstanding any failure to pay, the loan has sufficient collateral value and is in the process of collection.

Dividend income on preferred equity securities is recorded on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly-traded portfolio companies.

Other Income

From time to time, the Company may receive fees for services provided to portfolio companies by the Adviser. The services that the Adviser provides vary by investment, but may include syndication, structuring, diligence fees, or other service-based fees and fees for providing managerial assistance to our portfolio companies and are recognized as revenue when earned.

Earnings per share

The Company’s earnings per share (“EPS”) amounts have been computed based on the weighted-average number of shares of common stock outstanding for the period. Basic EPS is computed by dividing net increase (decrease) in net assets resulting from operations by the weighted average number of shares of common stock outstanding during the period. Diluted EPS is computed by dividing net increase (decrease) in net assets resulting from operations by the weighted average number of shares of common stock assuming all potential shares had been issued and the additional shares of common stock were dilutive. Diluted EPS reflects the potential dilution, using the if-converted method for convertible debt, which could occur if all potentially dilutive securities were exercised.

Reimbursement of Transaction-Related Expenses

The Company may receive reimbursement for certain transaction-related expenses in pursuing investments. Transaction-related expenses, which are expected to be reimbursed by third parties, are typically deferred until the transaction is consummated and are recorded in Prepaid expenses and other assets on the date incurred. The transaction-related costs of pursuing investments not otherwise reimbursed are borne by the Company and for successfully completed investments included as a component of the investment’s cost basis.

Cash advances received in respect of transaction-related expenses are recorded as Cash and cash equivalents with an offset to Other liabilities or Other payables to affiliates. Other liabilities or Other payables to affiliates are relieved as reimbursable expenses are incurred.

Income Taxes, Including Excise Taxes

The Company has elected to be treated as a RIC under Subchapter M of the Code, and the Company intends to operate in a manner so as to continue to qualify for the tax treatment applicable to RICs. To qualify as a RIC, the Company must, among other things, distribute to its stockholders in each taxable year generally at least 90 % of its investment company taxable income, as defined by the Code, and net tax-exempt income for that taxable year. To maintain its RIC status, the Company, among other things, has made and intends to continue to make the requisite distributions to its stockholders, which generally relieves the Company from corporate-level U.S. federal income taxes.

The Company evaluates tax positions taken or expected to be taken in the course of preparing its financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are reserved and recorded as a tax benefit or expense in the current year. All penalties and interest associated with income taxes are included in income tax expense. Conclusions regarding tax positions are subject to review and may be adjusted at a later date based on factors including, but not limited to, on-going analyses of tax laws, regulations and interpretations thereof. As of December 31, 2025, the Company did not have any uncertain tax positions that met the recognition or measurement criteria, nor did the Company have any unrecognized tax benefits. The Company’s 2024, 2023 and 2022 tax year returns remain subject to examination by the relevant federal, state, and local tax authorities.

Depending on the level of taxable income earned in a tax year, the Company can be expected to carry forward taxable income (including net capital gains, if any) in excess of current year dividend distributions from the current tax year into the next tax year and pay a nondeductible 4 % U.S. federal excise tax on such taxable income, as required. To the extent that the Company determines that the estimated current year annual taxable income will be in excess of estimated current year dividend distributions from such income, the Company accrues excise tax on estimated excess taxable income.

For the calendar years ended December 31, 2025, December 31, 2024 and December 31, 2023 we recorded a net expense of $ 5.3 million, $ 3.9 million and $ 2.4 million, respectively, for U.S. federal excise tax and other taxes.

For the calendar years ended December 31, 2025, December 31, 2024 and December 31, 2023 we recorded a deferred tax benefit of $ 0.5 million, a deferred tax liability of $ 2.6 million, and a deferred tax benefit of $ 0.6 million, respectively. For the calendar year ended December 31, 2025 we recognized a tax expense of $ 0.9 million pertaining to net realized gains.

Dividends to Common Stockholders

Dividends to common stockholders are recorded on the record date. The amount to be paid out as a dividend is determined by the Board and is generally based upon the earnings estimated by the Adviser. Net realized long-term capital gains, if any, would generally be distributed at least annually, although the Company may decide to retain such capital gains.

The Company has adopted a dividend reinvestment plan that provides for reinvestment of any dividends declared in cash on behalf of stockholders, unless a stockholder elects to receive cash. As a result, if the Board authorizes, and it declares, a cash dividend, then the stockholders who have not “opted out” of the dividend reinvestment plan will have their cash dividends automatically reinvested in additional shares of the Company’s common stock, rather than receiving the cash dividend. The Company expects to use newly issued shares to satisfy the dividend reinvestment plan.

Segment Reporting

The Company has one reportable segment: Investment Activity. The Investment Activity segment generates revenue primarily in the form of interest income from the investments it holds. In addition, the Company may generate income from dividends on equity investments, capital gains on the sale of investments and various loan origination and other fees.

The Company’s chief operating decision maker (the “CODM”) is comprised of the senior executive committee that includes the Chief Executive Officer, President, Chief Financial Officer, and the Deputy Chief Financial Officer.

The CODM uses the net increase (decrease) in net assets resulting from operations to evaluate income generated from segment investment activities. The evaluation and assessment of this metric is used in implementing investment policy decisions, strategic initiatives, managing the Company’s portfolio, evaluation of the Company’s distribution policy and assessing the performance of the portfolio.

The accounting policies of the Investment Activity segment are the same as those described in the summary of significant accounting policies. The CODM assesses performance for the segment and determines how to allocate resources based on the net increase (decrease) in net assets resulting from operations that also is reported on the consolidated statement of operations. Significant segment expenses are reported as total expenses on the consolidated statement of operations. The measure of segment assets is reported on the consolidated balance sheet as total assets.

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”),” which intends to improve the transparency of income tax disclosures. ASU No. 2023-09 is effective for fiscal years beginning after December 15, 2024 and is to be adopted on a prospective basis with the option to apply retrospectively. The Company adopted ASU 2023-09 effective December 31, 2025 and concluded that the application of this guidance did no t have any material impact on its consolidated financial statements.

In December 2024, the FASB issued ASU No. 2024-04, “Debt with Conversion and Other Options (Subtopic 470): Induced Conversions of Convertible Debt Instruments”, which clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as induced conversions rather than as debt extinguishments. This update is effective for annual periods beginning after December 15, 2025, including interim periods within those fiscal years, though early adoption is permitted. The Company does not expect this update to have a material effect on the Company’s consolidated financial statements.

In November 2025, the FASB issued ASU No. 2025-09, “Derivatives and Hedging (Topic 815): Hedge Accounting Improvements”, which intends to more closely align hedge accounting with the economics of an entity’s risk management activities. This update is effective for annual periods beginning after December 15, 2026, including interim periods within those fiscal years, though early adoption is permitted. The Company does not expect this update to have a material effect on the Company’s consolidated financial statements.

3. Agreements and Related Party Transactions

Administration Agreement

On March 15, 2011, the Company entered into the Administration Agreement with the Adviser. Under the terms of the Administration Agreement, the Adviser provides administrative services to the Company. These services include providing office space, equipment and office services, maintaining financial records, preparing reports to stockholders and reports filed with the SEC, and managing the payment of expenses and the oversight of the performance of administrative and professional services rendered by others. Certain of these services are reimbursable to the Adviser under the terms of the Administration Agreement. In addition, the Adviser is permitted to delegate its duties under the Administration Agreement to affiliates or third parties and the Company pays or reimburses the Adviser for certain expenses incurred by any such affiliates or third parties for work done on its behalf.

In February 2017, the Board of Directors of the Company and the Adviser entered into an amended and restated administration agreement (the “Administration Agreement”) reflecting certain clarifications to the agreement to provide greater detail regarding the scope of the reimbursable costs and expenses of the Administrator’s services.

In November 2025, the Board renewed the Administration Agreement. Unless earlier terminated as described below, the Administration Agreement will remain in effect until November 2026, and may be extended subject to required approvals. The Administration Agreement may be terminated by either party without penalty on 60 days’ written notice to the other party.

No person who is an officer, director or employee of the Adviser or its affiliates and who serves as a director of the Company receives any compensation from the Company for his or her services as a director. However, the Company reimburses the Adviser (or its affiliates) for the allocable portion of the costs of compensation, benefits, and related administrative expenses of the Company’s officers who provide operational and administrative services to the Company pursuant to the Administration Agreement, their respective staffs and other professionals who provide services to the Company (including, in each case, employees of the Adviser or an affiliate). Such reimbursable amounts include the allocable portion of the compensation paid by the Adviser or its affiliates to the Company’s Chief Financial Officer, Chief Compliance Officer, and other professionals who provide operational and administrative services to the Company pursuant to the Administration Agreement, including individuals who provide “back office” or “middle office” financial, operational, legal and/or compliance services to the Company. The Company reimburses the Adviser (or its affiliates) for the allocable portion of the compensation paid by the Adviser (or its affiliates) to such individuals based on the percentage of time those individuals devote, on an estimated basis, to the business and affairs of the Company and in acting on behalf of the Company. The Company may also reimburse the Adviser or its affiliates for the allocable portion of overhead expenses (including rent, office equipment and utilities) attributable thereto. Directors who are not affiliated with the Adviser receive compensation for their services and reimbursement of expenses incurred to attend meetings.

For the years ended December 31, 2025, December 31, 2024 and December 31, 2023, the Company incurred expenses of $ 3.9 million, $ 3.9 million and $ 3.2 million, respectively, for administrative services payable to the Adviser under the terms of the Administration Agreement, which is included in other general and administrative expenses in the Consolidated Statements of Operations.

Investment Advisory Agreement

On April 15, 2011, the Company entered into the Investment Advisory Agreement with the Adviser. The Investment Advisory Agreement was subsequently amended on December 12, 2011. Under the terms of the Investment Advisory Agreement, the Adviser provides investment advisory services to the Company. The Adviser’s services under the Investment Advisory Agreement are not exclusive, and the Adviser is free to furnish similar or other services to others so long as its services to the Company are not impaired. Under the terms of the Investment Advisory Agreement, the Company will pay the Adviser the Management Fee and may also pay certain Incentive Fees.

In November 2025, the Board renewed the Investment Advisory Agreement. Unless earlier terminated as described below, the Investment Advisory Agreement will remain in effect until November 2026, and may be extended subject to required approvals. The Investment Advisory Agreement may be terminated by either party without penalty on 60 days’ written notice to the other party.

The Management Fee is calculated at an annual rate of 1.5 % based on the average value of the Company’s gross assets calculated using the values at the end of the two most recently completed calendar quarters, adjusted for any share issuances or repurchases during the period. The Management Fee is payable quarterly in arrears.

For the years ended December 31, 2025, December 31, 2024 and December 31, 2023, Management Fees (gross of waivers) were $ 52.2 million, $ 51.8 million and $ 46.4 million, respectively.

Any waived Management Fees are not subject to recoupment by the Adviser.

The Adviser intends to waive a portion of the Management Fee payable under the Investment Advisory Agreement by reducing the Management Fee on assets financed using leverage over 200 % asset coverage (in other words, over 1.0x debt to equity) (the “Leverage Waiver”). Pursuant to the Leverage Waiver, the Adviser intends to waive the portion of the Management Fee in excess of an annual rate of 1.0 % ( 0.250 % per quarter) on the average value of the Company’s gross assets as of the end of the two most recently completed calendar quarters that exceeds the product of (i) 200 % and (ii) the average value of our net asset value at the end of the two most recently completed calendar quarters. For the years ended December 31, 2025, December 31, 2024 and December 31, 2023, Management Fees of $ 1.3 million, $ 1.5 million, and $ 1.2 million, respectively, have been waived pursuant to the Leverage Waiver.

The Incentive Fee consists of two parts, as follows:

The first component, payable at the end of each quarter in arrears, equals 100 % of the pre-Incentive Fee net investment income in excess of a 1.5 % quarterly “hurdle rate,” the calculation of which is further explained below, until the Adviser has received 17.5 % of the total pre-Incentive Fee net investment income for that quarter and, for pre-Incentive Fee net investment income in excess of 1.82 % quarterly, 17.5 % of all remaining pre-Incentive Fee net investment income for that quarter. The 100 % “catch-up” provision for pre-Incentive Fee net investment income in excess of the 1.5 % “hurdle rate” is intended to provide the Adviser with an Incentive Fee of 17.5 % on all pre-Incentive Fee net investment income when that amount equals 1.82 % in a quarter ( 7.28 % annualized), which is the rate at which catch-up is achieved. Once the “hurdle rate” is reached and catch-up is achieved, 17.5 % of any pre-Incentive Fee net investment income in excess of 1.82 % in any quarter is payable to the Adviser.

Pre-Incentive Fee net investment income means dividends, interest and fee income accrued by the Company during the calendar quarter, minus the Company’s operating expenses for the quarter (including the Management Fee, expenses payable under the Administration Agreement to the Administrator, and any interest expense and dividends paid on any issued and outstanding preferred stock, but excluding the Incentive Fee). Pre-Incentive Fee net investment income includes, in the case of investments with a deferred interest feature (such as original issue discount, debt instruments with pay-in-kind interest and zero coupon securities), accrued income that the Company may not have received in cash. Pre-Incentive Fee net investment income does not include any realized capital gains, realized capital losses or unrealized capital gains or losses.

The second component, payable at the end of each fiscal year in arrears, equaled 15 % through March 31, 2014 and, beginning April 1, 2014, equals a weighted percentage of cumulative realized capital gains from the Company’s inception to the end of that fiscal year, less cumulative realized capital losses and unrealized capital losses. This component of the Incentive Fee is referred to as the Capital Gains Fee. Each year, the fee paid for this component of the Incentive Fee is net of the aggregate amount of any previously paid Capital Gains Fee for prior periods. For capital gains that accrue following March 31, 2014, the Incentive Fee rate is 17.5 %. The Company accrues, but does not pay, a Capital Gains Fee with respect to unrealized capital gains because a Capital Gains Fee would be owed to the Adviser if the Company were to sell the relevant investment and realize a capital gain. The weighted percentage is intended to ensure that for each fiscal year following the completion of the IPO, the portion of the Company’s realized capital gains that accrued prior to March 31, 2014, is subject to an Incentive Fee rate of 15 % and the portion of the Company’s realized capital gains that accrued beginning April 1, 2014 is subject to an Incentive Fee rate of 17.5 %. In the determination of the second component of the Incentive Fee, any unrealized gains or losses specifically related to the foreign currency denominated borrowings of non-US dollar denominated investments is offset against any associated unrealized gains or losses related to foreign currency denominated investments. As of March 31, 2020, there are no remaining investments that were made prior to April 1, 2014, and as a result, the Incentive Fee rate of 17.5 % is applicable to any future realized capital gains.

For purposes of determining whether pre-Incentive Fee net investment income exceeds the hurdle rate, pre-Incentive Fee net investment income is expressed as a rate of return on the value of the Company’s net assets at the end of the immediately preceding calendar quarter.

Section 205(b)(3) of the Investment Advisers Act of 1940, as amended (the “Advisers Act”), prohibits the Adviser from receiving the payment of fees on unrealized gains until those gains are realized, if ever. There can be no assurance that such unrealized gains will be realized in the future.

For the years ended December 31, 2025, December 31, 2024 and December 31, 2023, Incentive Fees were $ 38.4 million, $ 40.2 million and $ 47.0 million, respectively, of which $ 43.5 million, $ 45.5 million and $ 42.6 million, respectively, were realized and payable to the Adviser. For the years ended December 31, 2025, December 31, 2024 and December 31, 2023, $( 5.1 ) million, $( 5.4 ) million, and $ 4.4 million, respectively, of Incentive Fees were accrued related to Capital Gains Fees. As of December 31, 2025, December 31, 2024 and December 31, 2023, these accrued Incentive Fees are not contractually payable to the Adviser.

Any waived Incentive Fees are not subject to recoupment by the Adviser.

Since the Company’s IPO, with the exception of its waiver of Management Fees and certain Incentive Fees attributable to the Company’s ownership of certain investments and the Leverage Waiver, the Adviser has not waived its right to receive any Management Fees or Incentive Fees payable pursuant to the Investment Advisory Agreement.

From time to time, the Adviser may pay amounts owed by the Company to third-party providers of goods or services, including the Board, and the Company will subsequently reimburse the Adviser for such amounts paid on its behalf. Amounts payable to the Adviser are settled in the normal course of business without formal payment terms.

4. Investments at Fair Value

Under the 1940 Act, the Company is required to separately identify non-controlled investments where it owns 5% or more of a portfolio company’s outstanding voting securities as investments in “affiliated” companies. In addition, under the 1940 Act, the Company is required to separately identify investments where it owns more than 25% of a portfolio company’s outstanding voting securities and/or had the power to exercise control over the management or policies of such portfolio company as investments in “controlled” companies. Detailed information with respect to the Company’s non-controlled, non-affiliated; non-controlled, affiliated; and controlled, affiliated investments is contained in the accompanying consolidated financial statements, including the Consolidated Schedules of Investments. The information in the tables below is presented on an aggregate portfolio basis, without regard to whether they are non-controlled, non-affiliated; non-controlled, affiliated; or controlled, affiliated investments.

As of December 31, 2024 , these interest rate swaps had either matured or been terminated due to repayment of the underlying investment or security.

For the years ended December 31, 2025 and December 31, 2024 , the Company recognized no net change in unrealized gains or losses, on interest rate swaps not designated as hedging instruments in the Consolidated Statement of Operations related to the swap transactions. For the years ended December 31, 2025 and December 31, 2024, the Company recognized a $ 34.5 million net change in gains and a $ 7.6 million net change in gains, respectively, on interest rate swaps designated as hedging instruments in the Consolidated Statements of Operations. For the years ended December 31, 2025 and December 31, 2024 , the Company recognized no net realized gain or loss on interest rate swaps. For the year ended December 31, 2024 , this amount is offset by an increase of $ 10.4 million for a change in the carrying value of the 2024 Notes. For the years ended December 31, 2025 and December 31, 2024, this amount is offset by an increase of $ 11.8 million and $ 8.5 million, respectively, for a change in carrying value of the 2026 Notes, an increase of $ 5.9 million and a decrease of $ 6.1 million, respectively, for a change in carrying value of the 2028 Notes, and an increase of $ 8.6 million and a decrease of $ 5.2 million, respectively, for a change in carrying value of the 2029 Notes. For the year ended December 31, 2025 this amount is offset by an increase of $ 8.3 million for a change in carrying value of the 2030 Notes.

As of December 31, 2025, the swap transactions had a fair value of $ 10.3 million, which is netted against cash collateral of $ 16.7 million. Cash is pledged as collateral under the Company’s derivative agreements and is included in restricted cash as a component of cash and cash equivalents on the Company’s Consolidated Balance Sheet. As of December 31, 2025, the derivatives had a fair value of $ 27.0 million. As of December 31, 2024 , the swap transactions had a fair value of $( 24.2 ) million, which is netted against cash collateral of $ 46.6 million.

The Company is required under the terms of its derivatives agreements to pledge assets as collateral to secure its obligations underlying the derivatives. The amount of collateral required varies over time based on the mark-to-market value, notional amount and remaining term of the derivatives, and may exceed the amount owed by the Company on a mark-to-market basis. Any failure by the Company to fulfill any collateral requirement (e.g., a so-called “margin call”) may result in a default. In the event of a default by a counterparty, the Company would be an unsecured creditor to the extent of any such overcollateralization.

The Company may enter into other derivative instruments and incur other exposures with the same or other counterparties in the future.

The Company typically determines the fair value of its performing Level 3 debt investments utilizing a yield analysis. In a yield analysis, a price is ascribed for each investment based upon an assessment of current and expected market yields for similar investments and risk profiles. Additional consideration is given to the expected life, portfolio company performance since close, and other terms and risks associated with an investment. Among other factors, a determinant of risk is the amount of leverage used by the portfolio company relative to the total enterprise value of the company, and the rights and remedies of our investment within each portfolio company’s capital structure.

Significant unobservable quantitative inputs typically considered in the fair value measurement of the Company’s Level 3 debt investments primarily include current market yields, including relevant market indices, but may also include quotes from brokers, dealers, and pricing services as indicated by comparable investments. If debt investments are credit impaired, an enterprise value analysis may be used to value such debt investments; however, in addition to the methods outlined above, other methods such as a liquidation or wind-down analysis may be utilized to estimate enterprise value. For the Company’s Level 3 equity investments, multiples of similar companies’ revenues, earnings before income taxes, depreciation and amortization (“EBITDA”) or some combination thereof and comparable market transactions are typically used.

Structured Credit Partners JV, LLC (“SCP”)

On December 23, 2025, affiliates of Sixth Street, including us, and affiliates of Carlyle entered into the Limited Liability Company Agreement to co-manage SCP, a joint venture focused on investing in broadly syndicated first lien senior secured loans, financed with long-term, non-mark-to-market, and predominantly investment grade rated CLO debt managed by affiliates of Sixth Street or Carlyle on a fee-free basis.

Sixth Street affiliates own 50.0 % of the equity interests in SCP and Carlyle affiliates own 50.0 %, with investment decisions requiring approval by representatives of both the Sixth Street affiliates and the Carlyle affiliates. SCP will be initially capitalized with $ 200.0 million of capital commitments from Sixth Street Specialty Lending, Inc., $ 100.0 million of capital commitments from Sixth Street Lending Partners, $ 150.0 million of capital commitments from Carlyle Secured Lending, Inc., and $ 150.0 million of capital commitments from Carlyle Credit Solutions, Inc., with all members of SCP having equal voting control. Equity contributions will be called from each member on a pro-rata basis, based on their equity commitments. Funding of such commitments requires the approval of SCP’s board of managers, including the board members appointed by the Company. SCP’s board of managers consists of an equal number of representatives appointed by the Sixth Street-affiliated members of SCP and the Carlyle-affiliated members of SCP. Portfolio construction and investment decisions must be unanimously approved by SCP’s investment committee, as delegated by the board of managers of SCP. Our investment in SCP is made with certain of our affiliates in accordance with the terms of the exemptive relief that we received from the SEC. Therefore, although the Company owns 25.0 % of the voting interests of SCP, the Company does not believe that it has control over SCP for accounting purposes and does not consolidate its non-controlling interest in SCP.

As of December 31, 2025, SCP had not commenced operations and no capital had been contributed to SCP.

Financial Instruments Not Carried at Fair Value

Debt

The fair value of the Company’s Revolving Credit Facility, which is categorized as Level 3 within the fair value hierarchy, as of December 31, 2025 and December 31, 2024, approximates its carrying value as the outstanding balance is callable at carrying value.

The following table presents the fair value of the Company’s 2026 Notes, 2028 Notes, 2029 Notes and 2030 Notes as of December 31, 2025 and December 31, 2024.

Under the fair value hierarchy, cash and cash equivalents are classified as Level 1 while the Company’s other assets and liabilities, other than investments at fair value and Revolving Credit Facility, are classified as Level 2.

7. Debt

Revolving Credit Facility

On August 23, 2012, the Company entered into a senior secured revolving credit agreement with Truist Bank (as a successor by merger to SunTrust Bank), as administrative agent, and J.P. Morgan Chase Bank, N.A., as syndication agent, and certain other lenders (as amended and restated, the “Revolving Credit Facility”).

As of December 31, 2025 , aggregate commitments under the Revolving Credit Facility were $ 1.675 billion. The Revolving Credit Facility includes an uncommitted accordion feature that allows the Company, under certain circumstances, to increase the size of the Revolving Credit Facility to up to $ 2.5 billion.

Pursuant to the Fifteenth Amendment dated April 24, 2024, aggregate commitments were increased to $ 1.7 billion. With respect to $ 1.505 billion of commitments, the revolving period was extended to April 24, 2028 and the stated maturity was extended to April 24, 2029 . For the remaining $ 195.0 million of commitments, (A) with respect to $ 25.0 million of commitments, the revolving period ended on February 4, 2025 and the stated maturity is February 4, 2026 and (B) with respect to $ 170.0 million of commitments, the revolving period ends April 24, 2026 and the stated maturity is April 23, 2027 .

Pursuant to the Sixteenth Amendment dated March 4, 2025, with respect to $ 1.525 billion of commitments, the revolving period, during which period we, subject to certain conditions, may make borrowings under the Revolving Credit Facility, was extended to March 2, 2029 and the stated maturity was extended to March 4, 2030 . For the remaining $ 150.0 million of commitments the revolving period ends April 24, 2026 and the stated maturity is April 23, 2027 .

The Revolving Credit Facility is guaranteed by Sixth Street SL SPV, LLC, TC Lending, LLC and Sixth Street SL Holding, LLC. The Revolving Credit Facility is secured by a perfected first-priority security interest in substantially all the portfolio investments held by the Company and each guarantor. Proceeds from borrowings may be used for general corporate purposes, including the funding of portfolio investments.

The Revolving Credit Facility includes customary events of default, as well as customary covenants, including restrictions on certain distributions and financial covenants. In accordance with the terms of the Sixteenth Amendment, the financial covenants require:

an asset coverage ratio of no less than 2 to 1 on the last day of any fiscal quarter;

stockholders’ equity of at least $ 650 million plus 25 % of the net proceeds of the sale of equity interest after April 24, 2024; and

a minimum asset coverage ratio of no less than 1.5 to 1 with respect to (i) the consolidated assets of the Company and the subsidiary guarantors (including certain limitations on the contribution of equity in financing subsidiaries) to (ii) the secured debt of the Company and its subsidiary guarantors plus unsecured senior securities of the Company and its subsidiary guarantors that mature within 90 days of the date of determination (the “Obligor Asset Coverage Ratio”).

The Revolving Credit Facility also contains certain additional concentration limits in connection with the calculation of the borrowing base, based on the Obligor Asset Coverage Ratio.

Net proceeds received from the Company’s issuance of the 2030 Notes were used to pay down borrowings on the Revolving Credit Facility.

9. Net Assets

On March 5, 2024, the Company issued a total of 4,000,000 shares of common stock at $ 20.52 per share. Net of underwriting fees and offering costs, the Company received total cash proceeds of $ 81.5 million. Subsequent to the offering, the Company issued an additional 600,000 shares on April 1, 2024 pursuant to the overallotment option granted to underwriters and received, net of offering and underwriting fees, additional total cash proceeds of $ 11.9 million.

The Company has a dividend reinvestment plan, whereby the Company may buy shares of its common stock in the open market or issue new shares in order to satisfy dividend reinvestment requests. The number of shares to be issued to a stockholder is determined by dividing the total dollar amount of the cash dividend or distribution payable to a stockholder by the market price per share of the Company’s common stock at the close of regular trading on the NYSE on the payment date of a distribution, or if no sale is reported for such day, the average of the reported bid and ask prices. However, if the market price per share on the payment date of a cash dividend or distribution exceeds the most recently computed net asset value per share, the Company will issue shares at the greater of (i) the most recently computed net asset value per share and (ii) 95 % of the current market price per share (or such lesser discount to the current market price per share that still exceeded the most recently computed net asset value per share). Shares purchased in open

market transactions by the plan administrator will be allocated to a stockholder based on the average purchase price, excluding any brokerage charges or other charges, of all shares of common stock purchased in the open market.

Pursuant to the Company’s dividend reinvestment plan, the following tables summarize the shares issued to stockholders who have not opted out of the Company’s dividend reinvestment plan during the years ended December 31, 2025 and December 31, 2024.

Under the program, we may repurchase up to $ 50 million in the aggregate of our outstanding common stock in the open market, from time to time, at certain thresholds below our net asset value per share, in accordance with the guidelines specified in Rule 10b-18 of the Exchange Act. The amount and timing of stock repurchases under the program may vary depending on market conditions, and no assurance can be given that any particular amount of common stock will be repurchased.

No shares were repurchased during the years ended December 31, 2025 and December 31, 2024.

Taxable Income

Note: Taxable income is an estimate and is not fully determined until the Company’s tax return is filed. The Company’s tax year changed from March 31 to December 31 during calendar year 2024.

Taxable income generally differs from increase in net assets resulting from operations due to temporary and permanent differences in the recognition of income and expenses, and generally excludes net unrealized gains or losses, as unrealized gains or losses are generally not included in taxable income until they are realized.

The Company makes certain adjustments to the classification of stockholders’ equity as a result of permanent book-to-tax differences, which include differences in the book and tax basis of certain assets and liabilities, and nondeductible federal taxes or losses among other items. To the extent these differences are permanent, they are charged or credited to additional paid in capital, or distributable earnings, as appropriate. In addition, due to the Company’s differing fiscal, tax, and excise tax year ends, the best estimates available are recorded to the above accounts in the period that such differences arise or are identifiable.

During the period January 1, 2025 through December 31, 2025 , the Company increased distributable earnings and decreased additional paid in capital by $ 6.3 million which was primarily attributable to U.S. federal excise taxes and other taxes.

During the period January 1, 2024 through December 31, 2024, the Company increased distributable earnings and decreased additional paid in capital by $ 3.8 million which was primarily attributable to U.S. federal excise taxes.

During the period April 1, 2023 through December 31, 2023, the Company increased distributable earnings and decreased additional paid in capital by $ 1.9 million which was primarily attributable to U.S. federal excise taxes.

The Company’s wholly-owned subsidiary, Sixth Street SL Holding, LLC, is a taxable subsidiary in which the Company holds certain equity investments. Sixth Street SL Holding, LLC is not consolidated for U.S. federal income tax purposes and may generate income tax expense as a result of its ownership of certain portfolio companies. The income tax expense, or benefit, and the related tax assets and liabilities, if any, are reflected in our Statement of Operations.

As of December 31, 2025 , the Company had a deferred tax liability of $ 4.6 million pertaining to net unrealized gains, related to seven of its investments. Given the unrealized gains generated by this entity, the deferred tax liability has been offset by a deferred tax asset of $ 0.6 million pertaining to operating losses. The Company recorded a deferred tax benefit of $ 0.5 million for the year ended December 31, 2025.

As of December 31, 2024 , the Company had a deferred tax liability of $ 5.2 million pertaining to net unrealized gains, related to eight of its investments. Given the unrealized gains generated by this entity, the deferred tax liability has been offset by a deferred tax asset of $ 0.6 million pertaining to operating losses. The Company recorded a current tax expense of $ 0.2 million and a deferred tax expense of $ 2.6 million for the year ended December 31, 2024.

As of December 31, 2023 , the Company had a deferred tax liability of $ 2.8 million pertaining to net unrealized gains, related to seven of its investments. Given the unrealized gains generated by this entity, the deferred tax liability has been offset by a deferred tax asset of $ 0.9 million pertaining to operating losses. The Company recorded a current tax expense of $ 0.1 million and a deferred tax benefit of $ 0.6 million for the year ended December 31, 2023.

The tax cost of the Company’s investments as of December 31, 2025 was $ 3,332,367 , resulting in estimated gross unrealized gains and losses of $ 219,540 and $ 231,975 , respectively. The tax cost of the Company’s investments as of December 31, 2024 was $ 3,535,963 , resulting in estimated gross unrealized gains and losses of $ 207,435 and $ 216,975 , respectively. The tax cost of the Company’s investments as of December 31, 2023 was $ 3,256,630 , resulting in estimated gross unrealized gains and losses of $ 159,281 and $ 135,606 , respectively.

To the extent that the Company determines that its estimated current year annual taxable income will exceed its estimated current year dividends from such taxable income, the Company accrues excise tax on estimated excess taxable income. For the year ended December 31, 2025, December 31, 2024 and December 31, 2023 , a net expense of $ 5.3 million, $ 3.8 million and $ 2.3 million, respectively, was recorded for U.S. federal excise tax.

Evaluation of Disclosure Controls and Procedures. As of the end of the period covered by this Annual Report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15 under the Exchange Act). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our current disclosure controls and procedures are effective in timely alerting them to material information relating to us that is required to be disclosed by us in the reports we file or submit under the Exchange Act.

Management’s Report on Internal Control Over Financial Reporting. Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act). Under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 COSO Framework). Based on our evaluation under the framework in Internal Control—Integrated Framework , management concluded that our internal control over financial reporting was effective as of December 31, 2025.

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.

Attestation Report of the Independent Registered Public Accounting Firm. Our independent registered public accounting firm, KPMG LLP, has issued an audit report on the effectiveness of our internal control over financial reporting, which is set forth under the heading “Report of Independent Registered Public Accounting Firm” on page F-2.
