FIDUS INVESTMENT CORPORATION ANNOUNCES

FOURTH QUARTER AND FULL YEAR 2019 FINANCIAL RESULTS

Regular Quarterly Dividend of $0.39 Per Share Declared for First Quarter 2020

EVANSTON, Ill., February 27, 2020 – Fidus Investment Corporation (NASDAQ:FDUS) (“Fidus” or the “Company”), a provider of customized debt and equity financing solutions, primarily to lower middle-market companies based in the United States, today announced its financial results for the fourth quarter and full year ended December 31, 2019.

Fourth Quarter 2019 Financial Highlights

Full Year 2019 Financial Highlights

Management Commentary

“Through steadfast underwriting discipline focused primarily on capital preservation during 2019, our portfolio remains healthy. For the fifth consecutive year, we delivered growth in NAV per share and the fair value of our investment portfolio increased 19% year over year while we received $120.6 million in proceeds from repayments, exits and realizations,” said Edward Ross, Chairman and CEO of Fidus Investment Corporation. “I am pleased to report that in February 2020 we successfully completed the partial sale of a portfolio of equity investments, generating $35.9 million in net proceeds and a net realized gain of approximately $20.4 million. We plan to redeploy these proceeds into income-producing investments continuing to focus on companies with defensive characteristics, strong free cash flow and positive long-term outlooks. As always, we remain committed to our long-term goals of generating attractive risk-adjusted returns from our debt and equity investments and delivering stable dividends.”

On a supplemental basis, we provide information relating to adjusted net investment income, which is a non-GAAP measure. This measure is provided in addition to, but not as a substitute for, net investment income. Adjusted net investment income represents net investment income excluding any capital gains incentive fee expense or (reversal) attributable to realized and unrealized gains and losses. The management agreement with our advisor provides

that a capital gains incentive fee is determined and paid annually with respect to cumulative realized capital gains (but not unrealized capital gains) to the extent such realized capital gains exceed realized and unrealized losses. In addition, we accrue, but do not pay, a capital gains incentive fee in connection with any unrealized capital appreciation, as appropriate. As such, we believe that adjusted net investment income is a useful indicator of operations exclusive of any capital gains incentive fee expense or (reversal) attributable to realized and unrealized gains and losses. The presentation of this additional information is not meant to be considered in isolation or as a substitute for financial results prepared in accordance with GAAP. Reconciliations of net investment income to adjusted net investment income are set forth in Schedule 1.

Fourth Quarter 2019 Financial Results

The following table provides a summary of our operating results for the three months ended December 31, 2019 as compared to the same period in 2018 (dollars in thousands, except per share data):

The $(2.7) million decrease in total investment income for the three months ended December 31, 2019 as compared to the same period in 2018 was primarily attributable to (i) a $1.1 million increase in total interest income (including payment-in-kind interest income) resulting from higher average debt investment balances outstanding, partially offset by a slight decrease in weighted average debt yield, (ii) a $(1.3) million decrease in fee income resulting from a decrease in prepayment fees and structuring fees on new investments, partially offset by an increase in amendment fees, and (iii) a $(2.5) million decrease in dividend income.

For the three months ended December 31, 2019, total expenses, including income tax provision, were $14.1 million, an increase of $3.0 million, or 27.2%, from the $11.1 million of total expenses, including income tax provision, for the three months ended December 31, 2018. The increase was primarily attributable to (i) a $1.3 million increase in interest and financing expenses due to an increase in average borrowings outstanding and an increase in weighted average interest rate on borrowings, (ii) a $0.4 million increase in the base management fee due to higher average total assets, and (iii) a $2.7 million increase in capital gains incentive fee accrued, partially offset by a $1.3 decrease in income incentive fee accrued.

Net investment income decreased by $(5.7) million, or (51.6)%, to $5.4 million during the three months ended December 31, 2019 as compared to the same period in 2018, as a result of the $(2.7) million decrease in total investment income and the $3.0 million increase in total expenses, including income tax provision. Adjusted net investment income⁽¹⁾, which excludes the capital gains incentive fee accrual, decreased by $(3.0) million, or (26.6%), to $8.3 million.

For the three months ended December 31, 2019, the total net realized loss on investments, net of income tax provision on realized gains, was $(9.9) million, as compared to total net realized gain on investments, net of income tax provision on realized gains, of $5.5 million for the same period in 2018.

Full Year 2019 Financial Results

The following table provides a summary of our operating results for the year ended December 31, 2019 as compared to the same period in 2018 (dollars in thousands, except per share data):

The $0.7 million increase in total investment income for the year ended December 31, 2019 as compared to the same period in 2018 was primarily attributable to (i) a $3.8 million increase in total interest income (including payment-in-kind interest income) resulting from higher average debt investment balances outstanding, partially offset by a decrease in weighted average debt investment yield, (ii) a $(2.6) million decrease in dividend income due to decreased levels of distributions received from equity investments, and (iii) a $(0.5) million decrease in fee income resulting from a decrease in prepayment fee income, partially offset by a increase in debt amendment and origination fee income.

For the year ended December 31, 2019, total expenses, including income tax provision, were $45.1 million, an increase of $3.7 million or 9.1%, from the $41.4 million of total expenses, including income tax provision, for the year ended December 31, 2018. The increase was primarily attributable to (i) a $4.4 million increase in interest and financing expenses due to an increase in average borrowings outstanding and an increase in weighted average interest rate on borrowings, (ii) a $1.0 million increase in base management fees due to higher average total assets, and (iii) a $(2.0) million decrease in income incentive fees offset by a $0.4 million increase in capital gains incentive fees accrued.

Net investment income decreased by $(3.1) million, or 8.8%, to $32.0 million during the year ended December 31, 2019 as compared to the same period in 2018, as a result of the $0.7 million increase in total investment income more than offset by a $3.7 million increase in total expenses, including income tax provision. Adjusted net investment income⁽¹⁾, which excludes the capital gains incentive fee accrual, decreased by $2.7 million, or 7.2%, to $35.3 million.

For the year ended December 31, 2019, the total net realized loss on investments, net of income tax provision on realized gains, was $(1.3) million, as compared to total net realized loss on investments, net of income tax provision on realized gains, of $(11.0) million for the same period in 2018.

Portfolio and Investment Activities

As of December 31, 2019, the fair value of our investment portfolio totaled $766.9 million and consisted of 61 active portfolio companies and three portfolio companies that have sold their underlying operations. Our total portfolio investments at fair value were approximately 108.9% of the related cost basis as of December 31, 2019. As of December 31, 2019, 17 portfolio company’s debt investments bore interest at a variable rate, which represented $181.3 million, or 28.7%, of our debt investment portfolio on a fair value basis, and the remainder of our debt investment portfolio was comprised of fixed rate investments. As of December 31, 2019, our average active portfolio company investment at amortized cost was $11.5 million, which excludes investments in the three portfolio companies that have sold their underlying operations. The weighted average yield on debt investments was 12.0% as of December 31, 2019. The weighted average yield was computed using the effective interest rates for debt investments at cost as of December 31, 2019, including the accretion of OID and loan origination fees, but excluding investments on non-accrual status, if any.

Fourth quarter 2019 investment activity included the following new portfolio company investments:

As of December 31, 2019, we had debt investments in one portfolio company on non-accrual status, which had an aggregate cost and fair value of $35.3 million and $33.1 million, respectively.

Liquidity and Capital Resources

As of December 31, 2019, we had $15.0 million in cash and cash equivalents and $75.0 million of unused capacity under our senior secured revolving credit facility (the “Credit Facility”). As of December 31, 2019, we had SBA debentures outstanding of $157.5 million, $50.0 million outstanding of our 5.875% notes due 2023 (the “2023 Notes”), $69.0 million outstanding of our 6.000% notes due 2024, $63.3 million outstanding of our 5.375% notes due 2024 (the “November 2024 Notes” and collectively with the 2023 Notes and February 2024 Notes, the “Public Notes”), and $25.0 million outstanding under our Credit Facility. As of December 31, 2019, the weighted average interest rate on total debt outstanding was 4.7%.

Subsequent Events

On January 10, 2020, we received a distribution on our equity investment in Fiber Materials Inc., resulting in a realized gain of approximately $9.8 million.

On January 29, 2020, we exited our debt investment in Hunter Defense Technologies, Inc. We received payment in full of $9.2 million on our first lien debt.

On January 31, 2020, we invested $11.0 million in a revolving loan and first lien debt of Combined Systems, Inc., a leading designer, manufacturer, and marketer of non-lethal security products for the global defense and law enforcement markets.

On February 7, 2020, we invested $15.0 million in first lien debt of Routeware, Inc., a leading provider of highly integrated fleet automation software and systems for waste haulers and municipalities.

On February 25, 2020, we sold 50% of our equity investments in 20 portfolio companies and received net proceeds of $35.9 million, resulting in a realized gain, net of estimated taxes, of approximately $20.4 million.

First Quarter 2020 Dividend of $0.39 Per Share Declared

On February 12, 2020 our board of directors declared a regular quarterly dividend of $0.39 per share payable on March 27, 2020 to stockholders of record as of March 13, 2020.

When declaring dividends, our Board of Directors reviews estimates of taxable income available for distribution, which differs from consolidated income under generally accepted accounting principles due to (i) changes in unrealized appreciation and depreciation, (ii) temporary and permanent differences in income and expense recognition, and (iii) the amount of undistributed taxable income carried over from a given year for distribution in the following year. The final determination of 2020 taxable income, as well as the tax attributes for 2020 dividends, will be made after the close of the 2020 tax year. The final tax attributes for 2020 dividends will generally include ordinary taxable income but may also include capital gains, qualified dividends and return of capital.

Fidus has adopted a dividend reinvestment plan (“DRIP”) that provides for reinvestment of dividends on behalf of its stockholders, unless a stockholder elects to receive cash. As a result, when we declare a cash dividend, stockholders who have not “opted out” of the DRIP at least two days prior to the dividend payment date will have their cash dividends automatically reinvested in additional shares of our common stock. Those stockholders whose shares are held by a broker or other financial intermediary may receive dividends in cash by notifying their broker or other financial intermediary of their election.

Supplemental Information Regarding Adjusted Net Investment Income

On a supplemental basis, we provide information relating to adjusted net investment income, which is a non-GAAP measure. This measure is provided in addition to, but not as a substitute for, net investment income. Adjusted net investment income represents net investment income excluding any capital gains incentive fee expense or (reversal) attributable to realized and unrealized gains and losses. The management agreement with our advisor provides that a capital gains incentive fee is determined and paid annually with respect to cumulative realized capital gains (but not unrealized capital gains) to the extent such realized capital gains exceed realized and unrealized losses for such year, less the aggregate amount of any capital gains incentive fees paid in all prior years. In addition, we accrue, but do not pay, a capital gains incentive fee in connection with any unrealized capital appreciation, as appropriate. As such, we believe that adjusted net investment income is a useful indicator of operations exclusive of any capital gains incentive fee expense or (reversal) attributable to realized and unrealized gains and losses. The presentation of this additional information is not meant to be considered in isolation or as a substitute for financial results prepared in accordance with GAAP. The following table provides a reconciliation of net investment income to adjusted net investment income for the three and 12 months and years ended December, 2019 and 2018.
