Summary of Quarterly Results First Fiscal Quarter 2019 Highlights − Net increase in net assets resulting from operations (i.e. net income) for the quarter ended December 31, 2018 was $18.7 million, or $0.28 per share, resulting in an annualized return on equity of 7.6%. This compares to net income of $18.8 million, or $0.32 per share, and an annualized return on equity of 8.4% for the quarter ended September 30, 2018. − Net investment income for the quarter ended December 31, 2018 was $20.2 million, or $0.31 per share, as compared to $21.3 million, or $0.37 per share for the quarter ended September 30, 2018. Excluding a $0.9 million reversal in the accrual for the capital gain incentive fee (net of waiver) under GAAP, net investment income for the quarter ended December 31, 2018 was $19.3 million, or $0.301 per share, as compared to $21.0 million, or $0.361 per share, excluding a $0.3 million reversal in the accrual for the capital gain incentive fee (net of waiver) under GAAP for the quarter ended September 30, 2018. − Net realized and unrealized loss on investments and foreign currency of $1.5 million, or $0.03 per share, for the quarter ended December 31, 2018 was the result of less than $0.1 million of net realized gains and $1.5 million of net unrealized depreciation. This compares to a net realized and unrealized loss on investments and foreign currency of $2.5 million, or $0.05 per share, for the quarter ended September 30, 2018. − New middle-market investment commitments totaled $262.8 million for the quarter ended December 31, 2018. Approximately 80% of the new investment commitments were one stop loans, 18% were senior secured loans, and 2% were investments in equity securities.

As a supplement to U.S. generally accepted accounting principles (“GAAP”) financial measures, Golub Capital Investment Corporation (“we,” “us,” “our,” “GCIC” and the “Company”) has provided this non-GAAP financial measure. The Company believes that this non-GAAP financial measure is useful as it excludes the accrual of the capital gain incentive fee which is not contractually payable under the terms of the Company’s investment advisory agreement with GC Advisors ( the “Investment Advisory Agreement”). The capital gain incentive fee payable as calculated under the Investment Advisory Agreement for the period ended December 31, 2018 is $0. However, in accordance with GAAP, the Company is required to include aggregate unrealized appreciation on investments in the calculation and accrue a capital gain incentive fee on a quarterly basis as if such unrealized capital appreciation were realized, even though such unrealized capital appreciation is not permitted to be considered in calculating the fee actually payable under the Investment Advisory Agreement. Although this non-GAAP financial measure is intended to enhance investors’ understanding of the Company’s business and performance, this non-GAAP financial measure should not be considered an alternative to GAAP. Refer to slide 4 for a reconciliation to the nearest GAAP measure, net investment income per weighted average share. 3

Income yield is calculated as (a) the actual amount earned on earning investments, including interest and fee income but excluding amortization of capitalized fees and discounts, divided by (b) the daily average of total earning investments at fair value. 6.
