INVESTMENT PRODUCTS: NOT FDIC OR SIPC INSURED • NO BANK GUARANTEE • MAY LOSE VALUE

An investment in the Fund is not appropriate for all and is not intended to be a complete investment program. An investment in the Fund involves risks, including the risk that you may receive little or no return on your investment or that you may lose part or even all of your investment. Therefore, prospective investors should consider carefully the Fund’s investment objectives, risks, charges and expenses and should consult with a tax, legal or financial advisor before making any investment decision. Shares of closed-end investment companies frequently trade at a discount from their .

The data shown in this fact card is subject to change on a daily basis.

Certain Risk Considerations Senior Loans. Senior loans are usually rated below investment grade and may also be unrated. As a result, the risks associated with senior loans are similar to the risks of below investment grade fixed income instruments and may be considered speculative. Senior loans are subject to a number of risks, including liquidity risk and the risk of non-payment of scheduled interest or principal. There may be less readily available and reliable information about most senior loans than is the case for many other types of securities. As a result, Apollo will rely primarily on its own evaluation of a borrower’s credit quality.

Corporate Bonds. The Fund may invest in a wide variety of bonds of varying maturities issued by U.S. and foreign corporations, other business entities, governments and municipalities and other issuers. The Fund’s investments in corporate bonds may include, but are not limited to, senior, junior, secured and unsecured bonds, notes and other debt securities, and may be fixed rate, variable rate or floating rate, among other things. Apollo expects most of the corporate bonds in which the Fund invests will be high yield bonds (commonly referred to as “junk” bonds), which may be considered speculative. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates. The value of intermediate and longer-term corporate bonds normally fluctuates more in response to changes in interest rates than does the value of shorter-term corporate bonds. The market value of a corporate bond also may be affected by investors’ perceptions of the creditworthiness of the issuer, the issuer’s performance and perceptions of the issuer in the marketplace.

Leverage Risk. The Fund intends to utilize leverage and may utilize leverage to the maximum extent permitted by law. The use of leverage to purchase additional securities creates an opportunity for increased common share dividends, but also creates risks for , including increased variability of the Fund’s net income, distributions and/or net asset value in relation to market changes. Leverage is a speculative technique that exposes the Fund to greater risk and increased costs than if it were not implemented. Increases and decreases in the value of the Fund’s portfolio will be magnified when the Fund uses leverage.

Libor Risk. Certain financial instruments in which the Fund invests may use a floating rate based on the London Interbank Offered Rate commonly known as “LIBOR”. Over the course of the last several years, global regulators have indicated an intent to phase out the use of LIBOR and similar interbank offering rates (IBORs). There still remains uncertainty regarding the nature of any replacement rates for LIBOR and the other IBORs as well as around fallback approaches for instruments extending beyond any phase-out of these reference rates. The lack of consensus around replacement rates and the uncertainty of the phase out of LIBOR and other IBORs may result in increased in corporate or governmental debt, bank loans, derivatives and other instruments invested in by the Fund as well as loan facilities used by the Fund. Certain proposed replacement rates to LIBOR, such as the Secured Overnight Financing Rate (“SOFR”), are materially different from LIBOR, and changes in the applicable spread for instruments previously linked to LIBOR will need to be made in order for instruments to pay similar rates. Uncertainty and risk also remain regarding the willingness and ability of issuers and lenders to include revised provisions in new and existing contracts or instruments. Consequently, the transition away from LIBOR to other reference rates may lead to reduced coupons on debt held by the Fund, higher rates required to be paid by the Fund on bank lines of credit due to increases in spreads, increased volatility and illiquidity in markets that are tied to LIBOR, fluctuations in values of LIBOR-related investments or investments in issuers that utilize LIBOR, increased difficulty in borrowing or refinancing and diminished effectiveness of hedging strategies, each of which could adversely affect the Fund’s performance and the issuers in which it invests. Because of the usefulness of LIBOR and the other IBORs as benchmarks could deteriorate during the transition period, these effects couldbegintobeexperiencedbytheendof2021andbeyonduntilthe anticipated discontinuance date in 2023 for the majority of the LIBOR rates.

Certain Risk Considerations (continued) Market Risk. Conditions affecting the general economy, including political, social, or economic instability at the local, regional, or global level may also affect the market value of a security. Health crises, such as pandemic and epidemic diseases, as well as other incidents that interrupt the expected course of events, such as natural disasters, war or civil disturbance, acts of terrorism, power outages and other unforeseeable and external events, and the public response to or fear of such diseases or events, have and may in the future have an adverse effect on the Fund’s investments and net asset value and can lead to increased market volatility. For example, any preventative or protective actions that governments may take in respect of such diseases or events may result in periods of business disruption, inability to obtain raw materials, supplies and component parts, and reduced or disrupted operations for the issuers in which the Fund invests. The occurrence and pendency of such diseases or events could adversely affect the economies and financial markets either in specific countries or worldwide.

The rapid and global spread of a highly contagious novel coronavirus respiratory disease, designated COVID-19, has resulted in volatility in the financial markets and widespread uncertainty regarding the duration and -term effects of this pandemic. Some sectors of the economy and individual issuers have experienced particularly large losses. In addition, the COVID-19 pandemic may result in a sustained domestic or even global economic downturn or recession. The U.S. government and the Federal Reserve, as well as certain foreign governments and central banks, are taking extraordinary actions to support local and global economies and the financial markets in response to the COVID-19 pandemic, including by pushing interest rates to very low levels. This and other government intervention into the economy and financial markets to address the COVID-19 pandemic may not work as intended. Government actions to mitigate the economic impact of thepandemichaveresultedinalargeexpansion of government deficits and debt, the long-term consequences of which are not known. The COVID-19 pandemic could adversely affect the value and liquidity of the Fund’s investments and negatively impact performance. In addition, the outbreak of COVID-19, and measures taken to mitigate its effects, could result in disruptions to the services provided to the Fund by its service providers.

Additional Risks. The Fund may be subject to additional risks, including, but not limited to, credit risk, risks of investing in below investment grade securities, interest rate risk, and risks of investing in illiquid securities.
