For variable rate loans that only have a Prime rate option, the contractual rate is calculated using current Prime at the time of funding, the spread over Prime and the impact of any Prime floor. For fixed rate loans, the contract rate is the stated fixed rate. 12 − Total investments at fair value increased by approximately 1.0%, or $44.3 million, during the quarter ended June 30, 2021. − As of June 30, 2021, we had $45.4 million of undrawn revolver commitments to portfolio companies.

The weighted average shares of the Company's common stock outstanding used in computing basic and diluted earnings per share for periods ending on or before June 30, 2020 have been adjusted retroactively by a factor of approximately 1.03% to recognize the bonus element associated with rights to acquire shares of the Company's common stock that were issued to stockholders of record as of April 8, 2020.
Financial Performance Highlights 20 * The quarterly return on equity for the periods up to and including FQ3 2019 are calculated as (a) the net increase in net assets resulting from operations (i.e., net income) for the period presented divided by (b) the daily average of total net assets during the period. The quarterly return on equity for the periods after FQ3 2019 are calculated as (a) adjusted net income for the period, as defined in the Endnotes at the end of this presentation, divided by (b) the daily average of total net assets during the period. Adjusted net income is a non-GAAP measure and the Company believes this non-GAAP measure is useful as it excludes the non-cash expense/loss from the purchase premium as further described in the Endnotes at the end of this presentation. These returns do not represent an actual return to any investor in the Company.

21 Long History of Strong Shareholder Returns Investors in GBDC’s 2010 IPO have achieved a 10.0% IRR on NAV1 1. Internal rate of return (“IRR”) on NAV is calculated using beginning of period NAV, distributions paid during the period, an incremental investment of $2.29 per share, or the GBDC Rights Offering subscription price of $9.17 per share divided by four (corresponding to the 1:4 issuance ratio in the GBDC Rights Offering, or the "GBDC Rights Offering Investment"), and ending period NAV, multiplied by 1.25x (corresponding to the 1:4 issuance ratio in the GBDC Rights Offering). Period beginning June 30, 2010 and ending June 30, 2021. GBDC made its initial public offering on April 15, 2010. 2. Calculated as (a) the sum of (i) NAV per share for the period presented plus (ii) cumulative regular and special distributions paid per share subsequent to the GBDC Rights Offering (b) divided by four to reflect additional shares purchased at the 1:4 issuance ratio in the GBDC Rights Offering. Note: Amounts presented represent per share amounts for a hypothetical shareholder that purchased one share in GBDC’s initial public offering (“IPO”) on April 15, 2010 and subscribed for its pro rata rights through GBDC’s rights offering, which closed on May 15, 2020 (“GBDC Rights Offering”). For illustrative purposes only; does not reflect the actual returns of a specific GBDC investor. Past performance does not guarantee future results.

Appendix: Endnotes A
1. On September 16, 2019, the Company completed its acquisition of GCIC. The merger was accounted for under the asset acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) 805-50, Business Combinations — Related Issues. Under asset acquisition accounting, where the consideration paid to GCIC’s stockholders exceeded the relative fair values of the assets acquired, the premium paid by GBDC was allocated to the cost of the GCIC assets acquired by GBDC pro-rata based on their relative fair value. Immediately following the acquisition of GCIC, GBDC recorded its assets at their respective fair values and, as a result, the purchase premium allocated to the cost basis of the GCIC assets acquired was immediately recognized as unrealized depreciation on the Company's Consolidated Statement of Operations. The purchase premium allocated to investments in loan securities will amortize over the life of the loans through interest income with a corresponding reversal of the unrealized depreciation on the GCIC loans acquired through their ultimate disposition. The purchase premium allocated to investments in equity securities will not amortize over the life of the equity securities through interest income and, assuming no subsequent change to the fair value of the GCIC equity securities acquired and disposition of such equity securities at fair value, the Company will recognize a realized loss with a corresponding reversal of the unrealized depreciation upon disposition of the GCIC equity securities acquired. On May 15, 2020, the Company completed a transferable rights offering, issuing 33,451,902 shares at a subscription price of $9.17 per share. In accordance with ASC 260 – Earnings Per Share, it was determined the Company’s rights offering contained a bonus element as the exercise price at issuance was less than the fair market value of the stock. In accordance with ASC 260, basic and diluted EPS are required to be adjusted retroactively for the bonus element for all periods ending on or before June 30, 2020 by applying an adjustment factor to weighted average shares outstanding. The adjustment factor that was calculated in accordance with ASC 260 was 1.03%. As a supplement to U.S. generally accepted accounting principles (“GAAP”) financial measures, the Company has provided the following non-GAAP financial measures: “Adjusted Net Investment Income” and “Adjusted Net Investment Income Per Share” - excludes the amortization of the purchase premium and the accrual for the capital gain incentive fee required under GAAP (including the portion of such accrual that is not payable under GBDC’s investment advisory agreement) from net investment income calculated in accordance with GAAP. “Adjusted Net Realized and Unrealized Gain/(Loss)” and “Adjusted Net Realized and Unrealized Gain/(Loss) Per Share” - excludes the unrealized loss resulting from the purchase premium write-down and the corresponding reversal of the unrealized loss resulting from the amortization of the premium on loans or from the sale of equity investments from the determination of realized and unrealized gain/(loss) in accordance with GAAP. “Adjusted Net Income” and “Adjusted Earnings/(Loss) Per Share” – calculates net income and earnings per share based on Adjusted Net Investment Income and Adjusted Net Realized and Unrealized Gain/(Loss). “Adjusted Earnings/(Loss) Per Share” also excludes the impact of the retroactive adjustment to the weighted average shares calculation due to the rights offering and the resulting impact on earnings per share. The Company believes that excluding the financial impact of the purchase premium in the above non-GAAP financial measures is useful for investors as this is a non-cash expense/loss and is one method the Company uses to measure its financial condition and results of operations. In addition, the Company believes excluding the accrual of the capital gain incentive fee in the above non-GAAP financial measures is useful as a portion of such accrual is not contractually payable under the terms of either the Company’s current investment advisory agreement with GC Advisors, which was effective September 16, 2019, or its prior investment advisory agreement with GC Advisors, (each an, “Investment Advisory Agreement”). 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 either Investment Advisory Agreement. As of each of December 31, 2020, September 30, 2020, June 30, 2020, March 31, 2020, and September 30, 2019, the cumulative capital gain incentive fee accrued by the Company in accordance with GAAP is $0, and none was payable as a capital gain incentive fee pursuant to the current Investment Advisory Agreement as of December 31, 2020. Any payment due under the terms of the current Investment Advisory Agreement is based on the calculation at the end of each calendar year or upon termination of the Investment Advisory Agreement. The Company paid capital gain incentive fees in the amounts of $1.2 million and $1.6 million calculated in accordance with its prior Investment Advisory Agreement as of December 31, 2017 and 2018 , respectively. The Company did not pay any capital gain incentive fee under the Investment Advisory Agreement for any period ended prior to December 31, 2017. Finally, the Company believes excluding the impact of the retroactive adjustment to the weighted average shares calculation due the rights offering and the resulting impact on per share data is useful for investors as it presents per share financial data that is consistent with what was previously reported. Although these non-GAAP financial measures are intended to enhance investors’ understanding of the Company’s business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP. Refer to slide ‘Summary of Quarterly Results’ for a reconciliation to the nearest GAAP measures. 2. Purchase premium refers to the premium paid by GBDC to acquire GCIC in excess of the fair value of the assets acquired. Endnotes – Non-GAAP Financial Measures 26
