RESULTS OF OPERATIONS

Investment income

Total investment income for the three months ended March 31, 2018 and 2017 was $16.7 million and $19.8 million, respectively, and consisted of $12.6 million and $14.5 million of interest income on debt securities (which included PIK interest of $0.2 million and $0.8 million and prepayment premiums of $0.1 million and $0.1 million, respectively), $2.6 million and $3.1 million of dividend income, $1.0 million and $1.3 million of interest income on other income-producing securities, and $0.5 million and $0.9 million of other income, including fees from THL Credit’s managed vehicles, respectively.

The decrease in investment income compared to the prior period was primarily due to a contraction in the overall investment portfolio since March 31, 2017, which led to lower interest income, and lower dividend income from certain equity investments.

Expenses

Expenses for the three months ended March 31, 2018 and 2017 were $7.9 million and $10.1 million, respectively. For the three months ended March 31, 2018 and 2017, base management fees were $2.3 million and $2.6 million, incentive fees were $0.0 million and $1.3 million, administrator and other expenses were $1.6 million and $1.7 million and fees and expenses related to THL Credit’s borrowings were $3.9 million and $4.3 million, respectively. In addition, for the three months ended March 31, 2018 and 2017, THL Credit recorded an income tax provision related to its consolidated blocker corporations, excise and other taxes of $0.1 million and $0.2 million, respectively.

The decrease in operating expenses was due to lower incentive fees as a result of portfolio performance, lower borrowing expenses due to a decrease in average borrowings outstanding and lower base management fees as a result of portfolio contraction.

Net investment income

Net investment income totaled $8.8 million and $9.7 million for the three months ended March 31, 2018 and 2017, or $0.27 and $0.29 per share based upon 32,673,590 and 32,925,369 weighted average common shares outstanding, respectively.

Net investment income was lower due to a decrease in interest income from debt and income-producing securities as a result of contraction of the overall investment portfolio.

Net realized gains and losses on investments, net of income tax provision

For the three months ended March 31, 2018, THL Credit recognized a net realized loss on portfolio investments of $13.1 million, primarily related to a realized loss from the exit of its investments in Aerogroup International Inc. and losses from the initial restructuring of its Charming Charlie LLC investment as part of

3

bankruptcy proceedings. These losses were offset by a reversal of prior period unrealized depreciation totaling $10.6 million. For the three months ended March 31, 2017, THL Credit recognized a realized loss of $1.5 million on the sale of its two remaining CLO investments in Flagship VII, Ltd. and Flagship VIII, Ltd., which was offset by a reversal of prior period unrealized depreciation totaling the same amount. THL Credit also recognized a $0.6 million gain from an investment in Gryphon Partners 3.5, L.P.

Net change in unrealized appreciation (depreciation) on investments

For the three months ended March 31, 2018 and 2017, THL Credit’s investment portfolio had a net change in unrealized appreciation (depreciation) of $10.0 million and ($3.7) million, respectively.

The net change in unrealized appreciation on investments was driven primarily by the reversal of prior period net unrealized depreciation related to certain restructured and exited investments and the financial performance of certain portfolio companies.

Benefit for taxes on unrealized gain on investments

For the three months ended March 31, 2018 and 2017, THL Credit recognized an income tax (provision) benefit for taxes on unrealized gains of ($0.0) million and $0.2 million related to consolidated subsidiaries, respectively.

The change in provision for tax on unrealized gains on investments relates primarily to changes to the unrealized appreciation (depreciation) of the investments held in these taxable consolidated subsidiaries, other temporary differences and change in prior year estimates received from certain portfolio companies.

Change in net assets resulting from operations

Change in net assets resulting from operations totaled $6.3 million and $5.3 million, or $0.19 and $0.16 per share based upon 32,673,590 and 32,925,369 weighted average common shares outstanding, for the three months ended March 31, 2018 and 2017, respectively.

The increase in net assets resulting from operations for the respective periods is due primarily to net realized and unrealized gains and losses in the portfolio.

FINANCIAL CONDITION, INCLUDING LIQUIDITY AND CAPITAL RESOURCES

As of March 31, 2018, THL Credit had cash of $3.3 million. THL Credit’s liquidity and capital resources are derived from its credit facility, equity and debt raises and cash flows from operations, including investment sales and repayments, and income earned. THL Credit’s primary use of funds includes making investments in portfolio companies, payment of dividends to stockholders and funding operating expenses. THL Credit used, and expects to continue to use, these capital resources, together with proceeds from the turnover within the portfolio and from future public and private offerings of securities to finance its investment objectives.

As of March 31, 2018, THL Credit had $278.8 million in outstanding borrowings, which was comprised of $168.8 million outstanding on the revolving credit facility and $110.0 million of notes payable outstanding. As of March 31, 2018, borrowings outstanding had a weighted average interest rate of 5.29 percent. For the three months ended March 31, 2018, THL Credit borrowed $13.5 million and repaid $11.4 million under the revolving credit facility.

For the three months ended March 31, 2018, THL Credit operating activities provided cash of $6.4 million primarily in connection with the purchase and sales of investments. Its financing activities provided $2.1 million of net borrowings on its credit facility and used $8.8 million for distributions to stockholders.

For the three months ended March 31, 2017, THL Credit’s operating activities used cash of $19.8 million primarily from the purchase of investments, its financing activities provided $24.9 million in net borrowings on its credit facility and used $8.9 million for distributions to stockholders.

STOCK REPURCHASE PROGRAM

THL Credit has provided its stockholders with notice of its ability to repurchase shares of its common stock in accordance with 1940 Act requirements. On March 7, 2017, THL Credit’s Board of Directors authorized a $20.0 million stock repurchase program, which was extended on March 2, 2018. Unless extended by THL Credit’s Board of Directors, the stock repurchase program will expire on March 2, 2019. The timing and amount of any stock repurchases will depend on the terms and conditions of the repurchase program and no assurances can be given that any particular amount will be purchased. THL Credit will immediately retire all such shares of common stock that it purchases.

For the three months ended March 31, 2018 and 2017, there were no stock repurchases.

RECENT DEVELOPMENTS

From April 1, 2018 through May 2, 2018, THL Credit made follow-on investments of $8.5 million at a combined weighted average yield based upon cost at the time of the investment of 7.7%.

On April 24, 2018, Charming Charlie LLC emerged from Chapter 11 bankruptcy proceedings whereby THL Credit converted its DIP facilities, Pre-petition Term Loan and DIP Roll-up Term Loan into two new exit first lien term loans and a non-controlling common equity interest (THL Credit and other funds managed by the Advisor collectively have a controlling equity interest in Charming Charlie, LLC). On the same date, THL Credit funded $0.9 million of the remaining unfunded commitments under its DIP facilities and used an additional $2.2 million to purchase another lender’s existing DIP revolving credit facility, all of which converted to the exit first lien term loans. As a result of these transactions, THL Credit’s debt investment in Charming Charlie LLC is comprised of $24.6 million in the exit first lien term loans. In addition, THL Credit provided $8.9 million of commitments under a vendor financing facility.

On May 1, 2018, THL Credit received proceeds of $26.6 million from the repayment of its subordinated debt and realization of its preferred equity interest in A10 Capital, LLC, which included prepayment premiums of $0.3 million.

On May 1, 2018, THL Credit’s board of directors declared a dividend of $0.27 per share payable on June 29, 2018 to stockholders of record at the close of business on June 15, 2018.
