Monetization of the Legacy Full Circle Assets © 2018 Great Elm Capital Corp. In the 21 months since the Full Circle merger closed, we have been working diligently to monetize what was largely viewed as a challenged legacy portfolio, as evidenced by the steep discount to NAV at which Full Circle’s shares were trading prior to and subsequent to the merger announcement. During that time, we have exited 23 positions across 15 portfolio companies realizing an aggregate total return of approximately $4.4 million on these positions, representing approximately 108% of NAV, a significant achievement given the market’s assessment of this portfolio Subsequent to quarter end, we received a significant paydown on our investment in The Selling Source, LLC, further reducing our exposure to the legacy Full Circle portfolio. Additionally, subsequent to the close of the quarter, we monetized our warrants in RiceBran Technologies Corporation, another legacy Full Circle position. Including the paydown and sale brings the monetization of the day one legacy portfolio to approximately 73% of the cost basis Company Name Initial Cost IRR17 Cash-on-Cash Return Pristine Environments $ 10,574 10.78% 1.02x PR Wireless, Inc.

© 2018 Great Elm Capital Corp. Appendix

Appendix: General Risks Debt instruments are subject to credit and interest rate risks.   Credit risk refers to the likelihood that an obligor will default in the payment of principal or interest on an instrument. Financial strength and solvency of an obligor are the primary factors influencing credit risk. In addition, lack or inadequacy of collateral or credit enhancement for a debt instrument may affect its credit risk. Credit risk may change over the life of an instrument, and debt instruments that are rated by rating agencies are often reviewed and may be subject to downgrade. Our debt investments either are, or if rated would be, rated below investment grade by independent rating agencies. These “junk bonds” and “leveraged loans” are regarded as having predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal. They may be illiquid and difficult to value and typically do not require repayment of principal before maturity, which potentially heightens the risk that we may lose all or part of our investment.   Interest rate risk refers to the risks associated with market changes in interest rates. Interest rate changes may affect the value of a debt instrument indirectly (especially in the case of fixed rate obligations) or directly (especially in the case of an instrument whose rates are adjustable). In general, rising interest rates will negatively impact the price of a fixed rate debt instrument and falling interest rates will have a positive effect on price. Adjustable rate instruments also react to interest rate changes in a similar manner although generally to a lesser degree (depending, however, on the characteristics of the reset terms, including the index chosen, frequency of reset and reset caps or floors, among other factors).   GECC utilizes leverage to seek to enhance the yield and net asset value of its common stock. These objectives will not necessarily be achieved in all interest rate environments. The use of leverage involves risk, including the potential for higher volatility and greater declines of GECC’s net asset value, fluctuations of dividends and other distributions paid by GECC and the market price of GECC’s common stock, among others. The amount of leverage that GECC may employ at any particular time will depend on, among other things, our Board’s and our adviser’s assessment of market and other factors at the time of any proposed borrowing.   As part of our lending activities, we may purchase notes or make loans to companies that are experiencing significant financial or business difficulties, including companies involved in bankruptcy or other reorganization and liquidation proceedings. Although the terms of such financings may result in significant financial returns to us, they involve a substantial degree of risk. The level of analytical sophistication, both financial and legal, necessary for successful financing to companies experiencing significant business and financial difficulties is unusually high. We cannot assure you that we will correctly evaluate the value of the assets collateralizing our investments or the prospects for a successful reorganization or similar action. In any reorganization or liquidation proceeding relating to a portfolio company, we may lose all or part of the amounts advanced to the borrower or may be required to accept collateral with a value less than the amount of the investment advanced by us to the borrower. © 2018 Great Elm Capital Corp.
