FS CREDIT INCOME FUND

Supplement dated March 27, 2020
to
the Prospectus dated February 28, 2020

This supplement contains information which amends, supplements or modifies certain information contained in the Prospectus of FS Credit Income Fund (the “Fund”), dated February 28, 2020 (as may be supplemented and amended, the “Prospectus”). Capitalized terms used in this supplement have the same meanings as in the Prospectus, unless otherwise stated herein.

You should carefully consider the “Types of Investments and Related Risks” beginning on page 35 of the Prospectus before you decide to invest in the Fund’s Shares.

This supplement supplements the subsection of the Prospectus entitled “Types of Investments and Related Risks—Risks Relating to the Fund’s Investment Program” by inserting the following:

Pandemic Risk.   The continuing spread of an infectious respiratory illness caused by a novel strain of coronavirus (known as COVID-19) has caused volatility, severe market dislocations and liquidity constraints in many markets, including securities the Fund holds, and may adversely affect the Fund’s investments and operations. The outbreak was first detected in December 2019 and subsequently spread globally. The transmission of COVID-19 and efforts to contain its spread have resulted in travel restrictions and disruptions, closed international borders, enhanced health screenings at ports of entry and elsewhere, disruption of and delays in healthcare service preparation and delivery, quarantines, event and service cancellations or interruptions, disruptions to business operations (including staff reductions), supply chains and consumer activity, as well as general concern and uncertainty that has negatively affected the economic environment. These disruptions have led to instability in the market place, including stock market losses and overall volatility. The impact of COVID-19, and other infectious illness outbreaks, epidemics or pandemics that may arise in the future, could adversely affect the economies of many nations or the entire global economy, the financial performance of individual issuers, borrowers and sectors and the health of the markets generally in potentially significant and unforeseen ways. In addition, the impact of infectious illnesses, such as COVID-19, in emerging market countries may be greater due to generally less established healthcare systems. This crisis or other public health crises may exacerbate other pre-existing political, social and economic risks in certain countries or globally.

The foregoing could lead to a significant economic downturn or recession, increased market volatility, a greater number of market closures, higher default rates and adverse effects on the values and liquidity of securities or other assets. Such impacts, which may vary across asset classes, may adversely affect the performance of the Fund’s investments, the Fund and your investment in the Fund. In certain cases, an exchange or market may close or issue trading halts on either specific securities or even the entire market, which may result in the Fund being, among other things, unable to buy or sell certain securities or financial instruments or to accurately price its investments.

To satisfy any shareholder repurchase requests during periods of extreme volatility, such as those associated with COVID-19, it is more likely the Fund may be required to dispose of portfolio investments at unfavorable prices compared to their intrinsic value. You should review this prospectus and the SAI to understand the Fund’s discretion to implement temporary defensive measures.

The Fund and its investment adviser have in place business continuity plans reasonably designed to ensure that they maintain normal business operations, and that the Fund, its portfolio and assets are protected. However, in the event of a pandemic or an outbreak, such as COVID-19, there can be no assurance that the Fund, its advisers and service providers, or the Fund’s portfolio companies, will be able to maintain normal business operations for an extended period of time or will not lose the services of key personnel on a temporary or long-term basis due to illness or other reasons. A pandemic or disease could also impair the information technology and other operational systems upon which the Fund’s advisers rely and could otherwise disrupt the ability of the Fund’s service providers to perform essential tasks.

Governmental authorities and regulators throughout the world, such as the U.S. Federal Reserve, have in the past responded to major economic disruptions with changes to fiscal and monetary policy, including but not limited to, direct capital infusions, new monetary programs and dramatically lower interest rates. Certain of those policy changes are being implemented in response to the COVID-19 pandemic. Such policy changes may adversely affect the value, volatility and liquidity of dividend and interest paying securities. The effect of recent efforts undertaken by the U.S. Federal Reserve to address the economic impact of the COVID-19 pandemic, such as the reduction of the federal funds target rate, and other monetary and fiscal actions that may be taken by the U.S. federal government to stimulate the U.S. economy, are not yet fully known. The duration of the COVID-19 outbreak and its full impacts are unknown, resulting in a high degree of uncertainty for potentially extended periods of time.
