Business Description

Oaktree Specialty Lending Corporation, a Delaware corporation, or together with its subsidiaries, where applicable, the Company, which may also be referred to as “we,” “us” or “our”, is a specialty finance company dedicated to providing customized, one-stop credit solutions to companies with limited access to public or syndicated capital markets. We were formed in late 2007 and currently operate as a closed-end, externally managed, non-diversified management investment company that has elected to be regulated as a Business Development Company under the Investment Company Act of 1940, as amended, or the Investment Company Act. In addition, we have qualified and elected to be treated as a regulated investment company, or RIC, under the Internal Revenue Code of 1986, as amended, or the Code, for tax purposes. As a RIC, we generally will not have to pay corporate-level U.S. federal income taxes on any net ordinary income or net realized capital gains that we distribute to our stockholders if we meet certain source-of-income, income distribution and asset diversification requirements. We are externally managed by Oaktree Fund Advisors, LLC, which we also refer to as “Oaktree” or our “Adviser,” pursuant to an investment advisory agreement, as amended from time to time, or the Investment Advisory Agreement, between the Company and Oaktree. Oaktree is an affiliate of Oaktree Capital Management, L.P., or OCM, the Company's external investment adviser from October 17, 2017 through May 3, 2020. Oaktree Fund Administration, LLC, which we refer to as “Oaktree Administrator,” a subsidiary of OCM, provides certain administrative and other services necessary for us to operate. Our investment objective is to generate current income and capital appreciation by providing companies with flexible and innovative financing solutions, including first lien loans (which may include "unitranche" loans and "last out" first lien loans, which are loans that are second priority behind "first out" first lien loans), and second lien loans, unsecured and mezzanine loans, bonds, preferred equity and certain equity co-investments. We may also seek to generate capital appreciation and income through secondary investments at discounts to par in either private or syndicated transactions. Our portfolio may also include certain structured finance and other non-traditional structures. We invest in companies that typically possess resilient business models with strong underlying fundamentals. We intend to deploy capital across credit and economic cycles with a focus on long-term results, which we believe will enable us to build lasting partnerships with financial sponsors and management teams, and we may seek to opportunistically take advantage of dislocations in the financial markets and other situations that may benefit from our Adviser’s credit and structuring expertise. Sponsors may include financial sponsors, such as an institutional investor or a private equity firm, or a strategic entity seeking to invest in a portfolio company. Our Adviser is generally focused on middle-market companies, which we define as companies with enterprise values of between $100 million and $750 million. We expect our portfolio to include a mix of first and second lien loans, including asset backed loans, unitranche loans, mezzanine loans, unsecured loans, bonds, preferred equity and certain equity co-investments. Our portfolio may also include certain structured finance and other non-traditional structures. We generally invest in securities that are rated below investment grade by rating agencies or that would be rated below investment grade if they were rated. Below investment grade securities, which are often referred to as “high yield” and “junk,” have predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal. Our portfolio totaled $2.8 billion at fair value as of September 30, 2025 and was composed of 143 portfolio companies.…
