Management Commentary

Edgar Lee, Chief Executive Officer and Chief Investment Officer of Oaktree Specialty Lending said, “The fourth quarter completed a strong year for OCSL, highlighted by solid earnings growth and improved credit performance, including delivering the third consecutive quarter of increased NAV per share. Since we began managing OCSL a year ago, we have made significant progress in reducing credit risk in the portfolio and stabilizing NAV. During the fiscal year, we reducednon-core investments by $569 million while adding over $1.0 billion of new investments that are consistent with Oaktree’s investment philosophy. Core investments now represent 76 percent of our portfolio, up from 37 percent as of September 30, 2017. Given our substantial progress to date, we believe we are well positioned to further enhance our return on equity and deliver value to our shareholders in 2019.”

Portfolio and Investment Activity

As of September 30, 2018, the fair value of the Company’s investment portfolio was $1.5 billion and was comprised of investments in 113 companies. These included debt investments in 86 companies, the investments in Senior Loan Fund JV I, LLC (“SLF JV I”) and equity investments in 40 companies, including in SLF JV I and 2 private equity funds. Fourteen of the equity investments were in companies in which Oaktree Specialty Lending also had a debt investment.

At fair value, 95.0% of the Company’s portfolio as of September 30, 2018 consisted of debt investments, including 48.4% of first lien loans, 27.0% of second lien loans and 19.6% of unsecured debt investments, including the debt investments in SLF JV I.

As of September 30, 2018, SLF JV I had $314.2 million in assets, including senior secured loans to 40 portfolio companies. The joint venture generated income of $3.1 million for Oaktree Specialty Lending during the quarter ended September 30, 2018.

The weighted average yield on the Company’s debt investments as of September 30, 2018, including the return on the Company’s mezzanine note investments in SLF JV I, was 8.4%.

As of September 30, 2018, $1.2 billion of the Company’s debt investments, or 83.2% of the total debt portfolio, at fair value, had floating interest rates.

During the quarter ended September 30, 2018, the Company originated $228.4 million of investment commitments, including investments in 13 new and three existing portfolio companies, and funded $218.4 million of investments across new and existing portfolio companies.

During the quarter, the Company received $267.5 million of proceeds from various prepayments, exits, other paydowns and sales and exited 18 investments.

Results of Operations

Total investment income for the quarter ended September 30, 2018 was $38.2 million, including $35.3 million of cash interest income from portfolio investments, $0.5 million ofpayment-in-kind (“PIK”) interest income, $2.0 million of fee income and $0.4 million of dividend income. PIK interest income, net of PIK collected in cash, represented 1.1% of total investment income for the quarter ended September 30, 2018. Total investment income increased $6.4 million from the quarter ended June 30, 2018, which was primarily attributable to the acceleration of interest income and prepayments fees earned in connection with the exit of a certain investment.

Net expenses for the quarter were $21.2 million, an increase of $3.8 million from the quarter ended June 30, 2018. The increase in net expenses was due primarily to an increase in Part I incentive fees (net of fees waived) resulting from higher investment earnings during the quarter, and an increase in interest expense, which was attributable to higher levels of outstanding debt during the quarter.

Net realized and unrealized gain before taxes on the Company’s investment portfolio for the quarter ended September 30, 2018 was $16.9 million.

Liquidity and Capital Resources

As of September 30, 2018, the Company had $13.5 million of cash and cash equivalents (including restricted cash), total principal value of debt outstanding of $643.4 million and $359.0 million of undrawn capacity on its credit facility, subject to borrowing base and other limitations. The weighted average interest rate on debt outstanding was 5.1% as of September 30, 2018.

As of September 30, 2018, the Company’s total leverage ratio was 0.75xdebt-to-equity.

Distribution Declaration

The Company’s Board of Directors declared a quarterly distribution of $0.095 per share, payable on December 28, 2018 to stockholders of record on December 17, 2018.

Distributions are paid primarily from distributable (taxable) income. To the extent taxable earnings for a fiscal taxable year fall below the total amount of dividend distributions for that fiscal year, a portion of those distributions may be deemed a return of capital to the Company’s stockholders.

Portfolio Asset Quality

As of September 30, 2018, there were eight investments on which the Company had stopped accruing cash and/or PIK interest or original issue discount (“OID”) income that, in the aggregate, represented 14.5% of the Company’s debt portfolio at cost and 7.0% at fair value.
