FS Specialty Lending Fund listing preparation

Summary

On April 24, 2025, FS Specialty Lending Fund (the Fund) announced that its board of trustees (the Board) approved a plan to prepare for the listing of its common shares on the New York Stock Exchange (NYSE).

In advance of the listing, the Fund will be converted from a business development company (BDC) to a closed-end fund registered under the Investment Company Act of 1940 (1940 Act), through a reorganization into a newly formed closed-end fund. The reorganization is subject to shareholder approval.

The closed-end fund (FSSL) will be named “FS Specialty Lending Fund” and we currently expect its common shares to begin trading on the NYSE under the ticker symbol “FSSL” before the end of the fourth quarter of 2025, subject to market conditions, shareholder approval, and final Board approval. Although we are working toward a listing within the targeted time frame, the timing may be subject to change based on a variety of factors.

Please note that this FAQ, along with other materials related to the listing preparation, will be updated in the coming months based on the timeline below. For the latest information, please visit www.FSproxy.com.

Liquidity plan overview

Timeline and shareholder considerations

Ticker symbol	Ticker symbol: FSSL
Expected timeline	·    April: Registration statement containing proxy statement/prospectus to be filed with the U.S. Securities and Exchange Commission (SEC). This filing will include three shareholder proposals related to the Fund’s proposed conversion to a registered closed-end fund. Shareholder approval of these proposals is a prerequisite for a listing. ·    Mid-May: The Fund intends to conduct a 6-for-1 reverse share split of its common shares and consolidate account types under a new CUSIP. ·    Late June: Shareholder proxy solicitation expected to commence. ·    Late Q3 / early Q4 2025: Target listing on the NYSE, subject to market conditions, approval of the NYSE, satisfaction of the NYSE’s listing standards, shareholder approval of the proposals related to the Fund’s reorganization to a registered closed-end fund, and final Board approval.
Conversion to a registered closed-end fund	·    The Fund will be converted from a business development company into a closed-end fund registered under the 1940 Act through a reorganization into a newly formed closed-end fund. The reorganization is subject to shareholder approval. ·    FSSL, the closed-end fund, will maintain the same board, investment objectives and strategy as the Fund* ·    The closed-end fund will be named “FS Specialty Lending Fund” and intends to pursue a listing of its shares on the NYSE.
Reverse share split	·    Prior to the conversion, the Fund intends to conduct a 6-for-1 reverse split of its common shares. Following the split, shareholders will own one share for every six shares held before the split. ·    The reverse share split is designed to achieve the following objectives: ‒    Comply with NYSE listing requirements which mandate a minimum stock price of $4.00 per share at the time of listing. As of December 31, 2024, the Fund’s net asset value (NAV) was $3.30 per share. ‒    Align the share price with the typical trading range of comparable closed-end funds, which have historically traded in the range of approximately $10 to $20 per share. ‒    Meet the minimum share price requirements for certain intermediaries, broker dealers and custodians. ·    The effective date of the share split is expected to be on or about May 15, 2025.
Quarterly repurchase offer	·    We expect the quarterly tender offers to remain suspended until the listing, at which point all shares will become freely tradable on the NYSE.

*The investment strategy will remain the same except for certain requirements specific to BDCs under the 1940 Act, which won’t apply once the Fund is converted to a closed-end fund.

As of April 24, 2025

Investment and fund management

Management team	·    The Fund’s Adviser is currently jointly operated by an affiliate of FS Investments and EIG Asset Management, LLC. As part of the conversion to a closed-end fund, FS Investments will acquire EIG’s interest in the Adviser, making the Adviser an indirect, wholly-owned subsidiary of FS Investments. ·    The Adviser will continue managing the Fund, with FS Investments’ Global Credit Team assuming full investment management responsibilities. This team has played a central role in the Fund’s transition to a diversified credit strategy since May 2023.
Fee changes	·    Upon a listing, the base management fee will be reduced from 1.75% to 1.50% of gross assets. The Adviser has agreed to waive 0.15% of the fee, resulting in an effective base management fee of 1.35% on gross assets, effective upon the listing and continuing for as long as the FSSL remains a registered closed-end fund.1 ·    The Adviser currently may earn incentive fees consisting of two components: (i) a capital gains incentive fee and (ii) a subordinated income incentive fee. ‒   Following the conversion and reorganization into a closed-end fund, the Adviser will no longer be entitled to a capital gains incentive fee. ‒   Upon listing and continuing for as long as FSSL remains a registered closed-end fund, the Adviser has agreed to waive a portion of the income incentive fee, reducing it from 20% to 10% subject to an annualized hurdle rate of 6.0%.2
Distributions	·    We expect the Fund to pay enhanced quarterly distributions for Q1 and Q2 2025, paid in April and July, respectively, based on an annualized distribution rate of 12.5% based on FSSL’s then-current NAV. ·    The Fund’s quarterly enhanced distributions were designed to offer attractive returns to shareholders during the transition period to a diversified credit strategy, with the understanding that they were intended to conclude once the Fund achieves a long-term liquidity event, and a portion of the distributions may represent a return of capital. ·    If a listing occurs prior to the end of the third quarter of 2025, we expect FSSL to pay a full quarterly enhanced distribution for the third quarter, payable in October. In the fourth quarter, we expect FSSL to target a monthly or quarterly distribution, representing an annualized distribution rate of 9.0% to 9.5% of FSSL’s NAV.3 ·    If a listing occurs in the fourth quarter of 2025, FSSL will pay a full quarterly enhanced distribution for the third quarter of 2025. In the fourth quarter, we expect FSSL to target a monthly or quarterly distribution, representing an annualized distribution rate of 9.0-9.5% of the Fund’s NAV.3 We believe this rate is competitive with those of closed-end fund peers and offers a meaningful income premium over risk-free rates. ·    Beginning in January 2026, we expect FSSL to declare and pay distributions on a monthly basis, subject to a listing occurring in 2025 and board approval. ·    Following the listing, all cash dividends or distributions declared by the Board will be reinvested on behalf of shareholders who do not elect to receive their distributions in cash. Shareholders who do not elect to “opt out” of FSSL’s distribution reinvestment plan (DRP) will have their shares automatically reinvested in additional shares.
Secondary market support	FS Investments and/or its affiliates are evaluating potential options for strengthening demand for FSSL’s shares in the secondary market.

As of April 24, 2025

1. Why list FSSL’s shares on the NYSE now?

Background

· In May 2023, the Fund announced Board-approved changes to the Fund’s name, investment objectives and investment strategy as part of a plan to transition from investing primarily in private U.S. energy and power companies to a diversified credit strategy spanning private and public credit across a broader range of industries, sectors and subsectors.

· The transition to a diversified credit strategy was designed to enhance shareholder returns, maximize the Fund’s long-term liquidity options, accelerate the timeline for a liquidity event and reduce the volatility associated with a single sector-focused strategy.

· We also communicated that the Fund would target a liquidity event by the end of Q3 2026 – within three years of the effective date of the changes to the Fund’s name, strategy and investment objectives. Potential liquidity options could include a public listing, merger, sale or another alternative as approved by the Board.

· To maximize the liquidity options, we believed the Fund’s strategy, asset mix, distribution, credit quality, and capital structure needed to be positioned to appeal to the broadest possible investor base – whether through the public markets (via a direct listing), a merger with an affiliate or competitor fund, or a sale to institutional asset managers.

Key metrics required to maximize long-term liquidity options

· Together with the Fund’s Board, we concluded that – regardless of the ultimate liquidity path for shareholders – the Fund must achieve a set of highly interdependent goals to maximize its commercial appeal to the broadest possible audience, including:

‒ Reduce energy holdings to approximately 20% or less of the portfolio’s fair value to create a more broadly diversified portfolio across industries, sectors and subsectors.

‒ Grow the Fund’s net investment income to support an annualized distribution rate that is competitive in the market, based on the Fund’s net asset value at the time of a liquidity event.

‒ Increase income-accruing investments to approximately 90% of the portfolio’s fair value by reducing the Fund’s allocation to common equity and underperforming debt investments.

Progress in reaching the key metrics required to maximize long-term liquidity options

· As of December 31, 2024, these key portfolio metrics were at or near our target range, and we believe the Fund is well-positioned for a liquidity event through a public listing.

‒ Energy investments represented 14.5% of the portfolio’s fair value as of December 31, 2024, well within our target threshold. The portfolio is broadly diversified across sectors and industries. Senior secured debt comprised 87% of the portfolio’s fair value as of December 31, 2024, reflecting our focus on high-quality, income-generating assets.

‒ Upon listing, we expect FSSL’s annualized distribution rate to be approximately 9.0-9.5% based on NAV, which is competitive with peers in the closed-end fund market.³ Subject to market conditions, fund performance and prevailing yields, we believe this level can be sustained over time by increasing FSSL’s allocation to higher-yielding private credit investments, optimizing borrowings, and further reducing exposure to non-income-producing assets.

In November 2024, the Fund received exemptive relief from the U.S. Securities and Exchange Commission (SEC) allowing it to co-invest in privately originated investments alongside certain other FS Investments-managed funds. We believe this added flexibility will help enhance the Fund’s ability to grow net investment income over time.

‒ Income-accruing investments represented 92% of the portfolio’s fair value as of December 31, 2024, compared to approximately 60% as of March 31, 2023.⁴ The increase was driven by our focus on exiting non-income producing equity investments and reducing assets on non-accrual.

· We believe a public listing offers a well-balanced liquidity solution–providing current shareholders with near-term access to liquidity, while preserving the opportunity for long-term value appreciation for those who choose to remain invested.

2. How will FSSL be differentiated in the public markets?

· Fully scaled credit platform with a significant market presence: As of December 31, 2024, the Fund managed approximately $2.1 billion in assets, which would rank as one of the largest public credit-focused registered closed-end funds. A relatively higher market capitalization and float (i.e., the number of shares available for public trading) compared to peers may enhance secondary market liquidity and attract a broader investor base upon listing.

· Proven management team: The Adviser will continue to manage FSSL with FS Investments’ Global Credit Team assuming full investment management responsibilities. The team has played a central role in the Fund’s transition to a diversified credit strategy since May 2023.

Formed in 2017, FS Investments’ Global Credit Team is led by Andrew Beckman and Nick Heilbut, seasoned credit investors with prior experience at DW Partners, Magnetar and Goldman Sachs’ Special Situations Multi-Strategy Group. Their vision was to bring the investment style they developed at Goldman to a broader investor base and build a global credit platform with diverse market exposure.

Team highlights:

‒ Manage $7.6 billion in assets for institutional and individual investors across registered closed end funds, private drawdown funds, collateralized loan obligations (CLO) and FSSL.

‒ Long-tenured leadership: Andrew Beckman and several senior team members have worked together for nearly 20 years, beginning in the early 2000s as part of Goldman Sachs’ Special Situations Multi-Strategy Group.

‒ Access to FS Investments’ $83 billion asset management platform: The team benefits from the resources, personnel, and infrastructure of FS Investments’ asset management platform, which provides a continuous flow of market insights to enhance the team’s underwriting, while seeking to generate strong shareholder returns.

‒ Deep middle market expertise: The team has significant experience sourcing, underwriting and managing investments in middle market companies with a specialized focus on lower and core middle market companies.

‒ Robust, multi-channel deal sourcing: The Fund leverages an extensive deal sourcing network spanning the investment management team and the broader firm, including a private sourcing partnership with J.P. Morgan, to originate differentiated investment opportunities.

· Dynamic strategy investing across private and public credit: The investment team aims to dynamically allocate capital to the most attractive opportunities across private and public credit in pursuit of return premiums. Unlike banks, insurance companies, or many private traditional credit strategies, the team is not constrained by a specific asset class mandate, allowing for greater adaptability in shifting market environments.

· Attractive distribution: We expect FSSL’s annualized distribution rate to be approximately 9.0-9.5%, based on its NAV at the time of listing. This rate is competitive with closed-end fund peers and offers a meaningful income premium over risk-free rates.³

3. Why didn’t the Fund liquidate its assets or wind down the portfolio upon transitioning to a diversified credit strategy?

· We did not believe that liquidating the portfolio or allowing it to simply run off would maximize shareholder value. In fact, pursuing that path could have prolonged the timeline before shareholders had the option for full liquidity of their investment compared to the current plan.

· At the start of 2023, the Fund’s portfolio was nearly entirely allocated to debt and equity investments in private U.S. energy companies. Due to the private nature of these investments and the absence of an active secondary market, an immediate or near-term sale could have forced the Fund to liquidate assets at 'fire sale' prices, which would ultimately harm long-term shareholder outcomes.

· For context, as of March 31, 2023 – just shy of the commencement of the transition plan to a diversified credit strategy – approximately 45% of the portfolio’s fair value was comprised of debt investments with maturities ranging from 1 to 9 years. The vast majority of the debt holdings were in illiquid, private debt investments. Additionally, approximately 23% of the portfolio was allocated to preferred equity investments with a weighted average maturity of 4 years, while 26% consisted of common and preferred equity investments with no stated maturity date.

5

· Equity investments do not have a stated maturity date, which makes the timing of a sale or exit inherently uncertain and subject to market conditions, portfolio company performance, and investor demand for energy assets, among other factors.

· The table below shows the maturity schedule for the portfolio as of March 31, 2023.

· Additionally, many of the Fund’s equity holdings were acquired through corporate restructurings. The COVID-driven collapse in energy demand and commodity prices severely impacted several of the Fund’s largest holdings, where we initially held the company’s debt. To reduce these companies’ debt burdens and support operational improvements, the Fund converted its debt holdings to equity to seek to maximize the recovery on its investment.

· Finally, non-accrual assets – investments that are not current on their contractual interest and principal payments –comprised approximately 13% of the portfolio’s fair value as of March 31, 2023. We believed the best way to maximize our recovery on these positions was to allow time for the companies to improve their operations and to exit when market conditions and the company fundamentals better aligned.

· Given the illiquid nature of the portfolio, the elevated level of non-accrual assets, and the Fund’s high concentration in restructured common equity investments and preferred equity investments, we determined that a liquidation or portfolio runoff would not have maximized shareholder value for several key reasons, including, but not limited to:

‒ It could have forced the Fund to accept prices below their intrinsic value.

‒ It would have increased the concentration risk in illiquid, non-income producing equity positions and non-performing debt investments as performing assets mature or were exited/sold.

‒ It would have limited the Fund’s ability to continue paying quarterly enhanced distributions.

‒ Finally, it would have reduced the Fund’s ability to achieve each key portfolio metric discussed above that we believe are essential for maximizing long-term liquidity options.

· The transition to a diversified credit strategy was designed to expand and maximize liquidity options for the Fund and our shareholders, offering a potentially faster, more efficient, and value-enhancing path to full liquidity compared to a liquidation or gradual runoff.

4. Why didn’t the Fund return capital to shareholders as the energy investments were exited or sold?

· Distributing proceeds from asset sales, exits, or repayments would have conflicted with the Fund’s ability to achieve the key portfolio metrics outlined above, which we believe are essential prerequisites for accelerating the timing of a long-term liquidity event that maximizes shareholder value.

· For example, distributing proceeds throughout the transition period would have:

‒ Limited the Fund’s ability to reinvest capital into income-producing assets, which is critical to growing net investment income and supporting an annualized distribution rate that is competitive in the market.

‒ Hindered progress toward reducing energy holdings to 20% or less of the portfolio’s fair value.

‒ Increased the concentration risk in illiquid, non-income producing equity positions and non-performing debt investments as performing assets matured or were exited/sold.

Listing and operational considerations

5. Why convert to a registered closed-end fund?

· The Fund will be converted from a business development company into a closed-end fund registered under the 1940 Act through a reorganization into a newly formed closed-end fund. The reorganization is subject to shareholder approval.

· The closed-end fund will maintain the same board, investment objectives and strategy as the Fund except for certain requirements specific to BDCs under the 1940 Act, which won’t apply once the Fund is converted to a closed-end fund.

· The closed-end fund will be named “FS Specialty Lending Fund” and intends to pursue a listing of its shares on the NYSE.

· The decision to convert the Fund to a registered closed-end fund was guided by several key factors that we believe are in the best interests of shareholders, including:

‒ Experienced management team: The Adviser will continue to manage FSSL, with FS Investments’ Global Credit Team assuming full investment management responsibilities. This team has played a central role in the Fund’s transition to a diversified credit strategy since May 2023.

The FS Global Credit team also manages FS Credit Opportunities Corp. (NYSE: FSCO), a publicly traded closed-end fund with a strategy similar to the Fund. FSCO was listed on the NYSE in November 2022 and has delivered strong returns since that time. We believe the Fund is well positioned to benefit from the team’s expertise, differentiated sourcing network, and deep investment experience across the combined platform.

‒ Distribution aligned with peers: At the time of listing, we expect FSSL’s annualized distribution rate to be approximately 9.0-9.5%, based on its NAV, making it competitive with closed-end fund peers and offering a significant income premium over risk-free rates.³

‒ Borrowings aligned with peers: As part of the transition to the diversified credit strategy, the Fund has used a modest level of borrowings relative to regulatory limits. While BDCs are permitted to borrow up to 2:1 debt-to-equity (i.e., borrow $2 dollars for every $1 of equity), as of December 31, 2024, the Fund’s debt-to-equity ratio was 0.33x. This level is consistent with closed-end fund peers, within our targeted ratio as a listed closed-end fund (0.25x-0.4x) and below the regulatory leverage limit applicable to closed-end funds (0.5x).

‒ Strong market visibility: As of December 31, 2024, the Fund managed approximately $2.1 billion in assets, which would rank as one of the largest public credit-focused registered closed-end funds. A relatively higher market capitalization and float (i.e., the number of shares available for public trading) compared to peers may enhance secondary market liquidity and attract a broader investor base upon listing.

6. What is the difference between a direct listing and an initial public offering (IPO)?

· We intend for FSSL’s common shares to begin trading through a direct listing on the NYSE – not an initial public offering – subject to various factors.

· This is an important distinction because, in an IPO, a company issues new shares and raises new capital in the public markets at an offering price and shares typically begin trading in the public markets based on the offering price.

· In contrast, FSSL’s direct listing does not involve the issuance of new shares, and the stock price will not be set prior to the listing.

· Instead, the public share price will be determined by market dynamics – specifically, the supply from existing shareholders looking to sell and demand from both existing and new investors seeking to purchase shares.

· If supply significantly exceeds demand at listing (i.e., more sellers than buyers) FSSL’s share price may decline and trade at a meaningful discount to its net asset value. Conversely, if supply and demand are more balanced, the share price may trade closer to NAV.⁵

7

As of April 24, 2025

· We believe a public listing offers a balanced liquidity solution by providing existing shareholders with near-term access to liquidity while preserving the opportunity for long-term value appreciation for those who choose to remain invested.

	FSSL’s direct listing	Initial public offering (IPO)
Initial trading price	Market-driven (supply & demand)	Based on offering price
New shares issued	No	Yes
New capital raised by company	No	Yes
Road shows with new potential investors	Yes	Yes

7. Have any previous direct listings been comparable to FSSL?

· While there is no exact market comparison to FSSL’s proposed listing, several direct listings of closed-end funds and BDCs offer relevant insights that may help inform expectations for the Fund’s listing.

· As illustrated in the chart below, heavy selling immediately following a listing is common, as shown by the gray bars. This pattern often reflects shareholders’ desire for near-term liquidity – frequently driven by factors beyond securing the best possible execution price.

· Over time, trading volumes typically decline, selling pressure eases, and share prices tend to trend higher as the market stabilizes and the investor base broadens.

· We believe a listing offers a balanced liquidity solution by providing existing shareholders with near-term access to liquidity while preserving the opportunity for long-term value appreciation for those who choose to remain invested.

· As we approach the listing date, we plan to conduct roadshows with institutional investors and financial advisory platforms to help build awareness for the fund’s common shares in the secondary market. Additionally, FS Investments and/or its affiliates are evaluating options for strengthening demand for the shares in the secondary market.

As of April 24, 2025

8. Will the listing change the management team or investment strategy?

· There will be no change to the Fund’s investment objectives or investment strategy except for certain requirements specific to BDCs under the 1940 Act, which won’t apply once the Fund is converted to a closed-end fund.

· Following the reorganization, the Fund will continue to be overseen by the same Board of Trustees who currently provide governance and oversight.

· The Fund’s Adviser is currently jointly operated by an affiliate of FS Investments and EIG Asset Management, LLC. As part of the conversion, FS Investments will acquire EIG’s interest in the Adviser, making the Adviser an indirect wholly-owned subsidiary of FS Investments.

· The Adviser will continue to manage the Fund, with FS Investments’ Global Credit Team assuming all investment management responsibilities. The team has played a central role in the transition to a diversified credit strategy since May 2023.

9. What is the purpose of the reverse share split?

· The Fund intends to conduct a 6-for-1 reverse share split in May 2025. Following the reverse split, shareholders will receive one share of the Fund’s common share for every six shares held before the reverse split.

· The reverse share split is designed to help achieve the following objectives:

‒ Comply with NYSE listing requirements which mandate a minimum stock price of $4.00 per share at the time of listing. As of December 31, 2024, the Fund’s net asset value was $3.30 per share.

‒ Align FSSL’s share price with the typical trading range of comparable closed-end funds, which have historically traded in the range of approximately $10 to $20 per share.

‒ Meet the minimum share price requirements for certain intermediaries, broker dealers and custodians.

· The reverse share split will not affect the rights or preferences of the Fund’s common shares.

· The Fund expects that the par value will remain unchanged at $0.001 per share following the reverse share split.

10. Will any changes occur to my account prior to the reverse share split?

· During the Fund’s offering period, shares were purchased through four different account types, based on the financial intermediary through which the shares were purchased. Each account type has a distinct CUSIP (an alphanumeric code used to identify financial securities) and fund number.

· Shortly prior to the reverse share split, the Fund will consolidate the existing account types into a main fund account with a new CUSIP as described below. This change will not affect shareholders’ account value, distributions or overall investment and shareholders do not need to take any action for this operational transaction.

· This consolidation is purely operational and designed to simplify and streamline the reverse share split process.

	Current account detail		Post-CUSIP consolidation
Fund Name	CUSIP	Fund #	CUSIP	Fund #
FS Specialty Lending Fund	30264D109	3804	New CUSIP to be issued	No change

As of April 24, 2025

11. Will the value of my investment change as a result of the reverse share split?

· No, a shareholder’s investment value will not change as a result of the reverse share split.

· In the example below, we assume a shareholder owns $10,000 worth of shares based on the Fund’s NAV as of December 31, 2024.

Illustrative example: 6-for-1 reverse stock split

	Before reverse stock split	6:1 reverse stock split	After reverse stock split
Net asset value per share*	$3.30	x 6 =	$19.80
Number of shares held	3,030	÷ 6 =	505
Shareholder value	$10,000	--	$10,000

*As of December 31, 2024

· Based on a 6-for-1 reverse share split ratio, shareholders will receive one share for every six shares held prior to the reverse split. To calculate the number of shares owned after the stock split, shareholders should divide the number of shares owned prior to the stock split by six.

· The shareholder owns 3,030 shares prior to the reverse split ($10,000 current value ÷ $3.30 NAV per share).

· Following the reverse stock split, the shareholder would own 505 shares (3,030 ÷ 6). The NAV per share increases in equal proportion from $3.30 to $19.80 ($3.30 x 6).

· As a result, the total value of the shareholder’s investment remains unchanged, while the number of shares held is reduced and the per-share value increases.

12. Is there any action a shareholder needs to take in advance of the reverse share split?

· Shareholders do not need to take any action for the reverse share split to take place.

· An account maintenance freeze will be implemented approximately two weeks prior to the effective date of the split. During this time, certain account maintenance activities, such as share transfers or updates to account information, will not be possible during the freeze. The freeze will be lifted once the reverse split is complete.

· We will continue to provide updates and communicate with shareholders as the effective date approaches.

13. Will the Fund’s management and incentive fees change?

· Upon a listing, the base management fee will be reduced from 1.75% to 1.50% of gross assets. In addition, the Adviser has agreed to waive 0.15% of the fee, resulting in an effective management fee of 1.35% on gross assets for as long as FSSL remains a registered closed-end fund.¹

· The Adviser currently may earn incentive fees consisting of two parts: (i) a capital gains incentive fee and (ii) a subordinated income incentive fee. Following the conversion to a closed-end fund, the Adviser will no longer earn a capital gains incentive fee.

· Upon a listing and continuing for so long as FSSL remains a registered closed-end fund, the Adviser has agreed to waive a portion of the income incentive fee, reducing it from 20% to 10%, subject to an annualized hurdle rate of 6.0%.²

14. Will the listing create a taxable event?

· The listing itself will not create a taxable event. However, if shareholders decide to sell their shares, they could be subject to taxes.

· Shareholders should consult with their financial and tax advisors before selling their shares in order to best understand their individual tax considerations.

15. Will the Fund or its affiliates provide support for the Fund’s stock in the secondary market?

· FS Investments and/or its affiliates are evaluating potential options for strengthening demand for FSSL’s shares in the secondary market.

10

16. What are the noteworthy next steps?

· There is no action required by shareholders until the commencement of the shareholder proxy solicitation, which we expect to begin in late June.

· See proxy statement/prospectus for further details.

Distributions

17. Will the Fund continue to pay quarterly enhanced distributions?

· We expect the Fund to pay enhanced quarterly distributions for Q1 and Q2 2025, paid in April and July, respectively, based on an annualized distribution rate of 12.5% based on the Fund’s then-current NAV.

· The Fund’s quarterly enhanced distributions were designed to offer attractive returns to shareholders during the transition period to a diversified credit strategy, with the understanding that they were intended to conclude once the Fund achieves a long-term liquidity event, and a portion of the distributions may represent a return of capital.

· Given our expectation for a listing in late Q3 or early Q4, we expect the quarterly enhanced distribution for Q3 will be the final quarterly enhanced distribution.

‒ If a listing occurs prior to the end of the third quarter of 2025, we expect FSSL to pay a full quarterly enhanced distribution for the third quarter, payable in October. In the fourth quarter we expect the closed-end fund to target a monthly or quarterly distribution representing an annualized distribution rate of 9.0% to 9.5% of FSSL’s NAV.³ We believe this rate is competitive with those of closed-end fund peers and offers a meaningful income premium over risk-free rates.

‒ If a listing occurs in the fourth quarter of 2025, FSSL will pay a full quarterly enhanced distribution for the third quarter of 2025. In the fourth quarter, we expect FSSL to target a monthly or quarterly distribution representing an annualized distribution rate of 9.0-9.5% of the Fund’s NAV.³

‒ Beginning in January 2026, we expect FSSL to declare and pay distributions on a monthly basis, subject to a listing occurring in 2025 and board approval.

· As previously communicated, we believe a portion of the enhanced quarterly distributions may represent a return of capital to investors on a tax basis. Tax characteristics for the Fund’s distributions are reported annually on shareholders’ Form 1099-DIV. In 2023 and 2024, 100% of the Fund’s distributions were funded through ordinary income on a tax basis. This was supported by the Fund’s undistributed taxable income from prior periods as well as one-time distributions from certain holdings, all which contributed to covering distributions through the Fund’s net investment income.

18. Will the Fund have a distribution reinvestment plan upon a listing?

· Yes. Following the listing, FSSL will reinvest all cash dividends or distributions declared by the board on behalf of shareholders who do not elect to receive their distributions in cash. As a result, shareholders who have not elected to “opt out” of the Fund’s distribution reinvestment plan (DRP) will have their shares automatically reinvested in additional shares.

· If the per share market price is equal to or greater than the estimated NAV per share on the payment date for a distribution, then FSSL will issue shares at the greater of (i) NAV per share or (ii) 95% of the market price. If the per share market price is less than NAV per share, then FSSL, at its discretion, will (i) purchase shares in the open market for accounts of participants where practicable, or (ii) issue shares at NAV per share.

19. What proposals will shareholders be asked to approve?

· Shareholders will be asked to vote on three proposals at the Fund’s special shareholder meeting, which we expect to take place in the third quarter of 2025. Shareholder approval of all three proposals is required for the listing to proceed in late Q3 or early Q4 2025.

· The first two proposals relate to amending the Fund’s Agreement and Declaration of Trust (DOT), the legal document that governs key aspects of its operations. Certain provisions in the current DOT would no longer be applicable to the Fund as a listed closed-end fund or could restrict its ability to reorganize as a closed-end fund and potentially hinder the execution of the Board-approved liquidity plan.

· Investors are strongly encouraged to review documents that the Fund will file with the Securities and Exchange Commission (SEC), including the proxy statement/prospectus when available. Subject to SEC review, we expect to seek shareholder approval beginning in late June 2025.

· The Board believes each of the proposals is in the best interests of the Fund and its shareholders and unanimously recommends a vote “FOR” each proposal.

Proposal	Description	Why this matters for shareholders
#1. To approve the amendment to the DOT to eliminate Article XII of the Declaration of Trust.	Certain provisions in the DOT currently prohibit the Fund from engaging in a “Roll-Up Transaction”, which includes acquisitions, mergers, conversions and other transactions. These provisions were originally adopted to comply with certain ‘blue sky’ regulations applicable during the Fund’s public offering but will no longer apply once the fund is listed as a closed-end fund. This proposal seeks to remove those provisions from the DOT to facilitate the Fund’s conversion to a closed-end fund through the reorganization.	Converting the Fund to a closed-end fund through a reorganization is a prerequisite for a listing.
#2. To approve the amendment of the Declaration of Trust to clarify the shareholder voting standard in connection with a merger or reorganization of the Fund that has been approved by the Board of Trustees.	This proposal seeks to amend the DOT to clarify the board and shareholder approval requirements for converting the Fund to a closed end fund through the reorganization. The current language may create ambiguity in interpreting the shareholder vote requirement. The proposed changes are intended to clarify this language and ensure alignment with the Fund’s planned conversion through the reorganization.	Converting the Fund to a closed-end fund through a reorganization is a prerequisite for a listing.
#3 To approve the Agreement and Plan of Reorganization	The Agreement and Plan of Reorganization outlines the proposed reorganization of the Fund through the merger of the Fund with and into a newly formed closed end fund. As part of the reorganization, all outstanding common shares of the Fund will be exchanged for newly issued shares of the closed-end fund. There will be no change to the Fund’s investment objectives or strategy and a portion of the management and incentive fees will be waived for as long as FSSL is a registered closed-end fund.	Approving the Agreement and Plan of Reorganization is a prerequisite for a listing.

20. What vote is required for each proposal to pass?

· Proposals 1 and 2 require approval by a majority of votes cast.

· Proposal 3 requires the affirmative vote of the lesser of (i) a majority of the Fund’s outstanding shares, or (ii) 67% or more of the shares present at the shareholder meeting, provided that a majority of the Fund’s outstanding shares are present at the meeting.

21. Will the Fund incur expenses in soliciting proxies?

· The expenses of the solicitation of proxies for the shareholder meetings, including the cost of preparing, printing and mailing the proxy statement, the applicable accompanying notice of the special shareholder meeting of shareholders and the proxy card, will be borne by the Fund.

· Broadridge Investor Communication Solutions, Inc. has been retained by the Fund to assist in the solicitation of proxies.

FOOTNOTES

1. For each quarter after the listing date, the base management fee will be reduced from 1.75% to 1.50% of gross assets. In addition, the Adviser has agreed to waive 0.15% of the fee, resulting in an effective base management fee of 1.35% on gross assets commencing upon the listing and continuing for as long as FSSL remains a registered closed-end fund. Amounts waived by the Adviser will not be subject to recoupment from FSSL.

2. Pursuant to the terms of FSSL’s Investment Advisory Agreement, for any quarter ending after the listing, the incentive fee on income is calculated and payable quarterly in arrears and equals 20.0% of FSSL’s “pre-incentive fee net investment income” for the immediately preceding quarter subject to a hurdle rate, expressed as a rate of return on net assets, equal to 1.5% per quarter, or an annualized hurdle rate of 6.0% compared to the current hurdle rate of 6.5%. As a result, the Adviser will not earn this incentive fee for any quarter until FSSL’s pre-incentive fee net investment income for such quarter exceeds the hurdle rate of 1.5%. Once FSSL’s pre-incentive fee net investment income in any quarter exceeds the hurdle rate, the Adviser will be entitled to a “catch-up” fee equal to the amount of FSSL’s pre-incentive fee net investment income in excess of the hurdle rate, until FSSL’s pre-incentive fee net investment income for such quarter equals 1.875%, or 7.5% annually, of net assets. This “catch-up” feature will allow the Adviser to recoup the fees foregone as a result of the existence of the hurdle rate. Thereafter, the Adviser will be entitled to receive 20.0% of FSSL’s pre-incentive fee net investment income.

While the incentive fee on income of the Fund and FSSL prior to the listing will be subject to a hurdle rate equal to a percentage of “adjusted capital” (as defined the Fund’s and FSSL’s Investment Advisory Agreement), the incentive fee on income of FSSL after the listing will be subject to a hurdle rate expressed as a rate of return on net assets, which will have the effect of making it more likely that the fund’s pre-incentive fee net investment income will exceed the hurdle rate and therefore more likely that FSSL will pay an incentive fee on income.

Effective on the listing and for so long as FSSL is a registered closed-end fund, the Adviser has contractually agreed to waive a portion of FSSL’s incentive fee. After giving effect to such fee waiver, the incentive fee on income will be calculated and payable quarterly in arrears and equals 10.00% of the closed-end fund’s “pre-incentive fee net investment income” for the immediately preceding quarter subject to a hurdle rate, expressed as a rate of return on net assets, equal to 1.5% per quarter, or an annualized hurdle rate of 6.0%. As a result, the Adviser will not earn this incentive fee for any quarter until FSSL’s pre-incentive fee net investment income for such quarter exceeds the hurdle rate of 1.5%. Once FSSL’s pre-incentive fee net investment income in any quarter exceeds the hurdle rate, the Adviser will be entitled to a “catch-up” fee equal to the amount of FSSL’s pre-incentive fee net investment income in excess of the hurdle rate, until the closed-end fund’s pre-incentive fee net investment income for such quarter equals 1.667%, or 6.667% annually, of net assets. This “catch-up” feature will allow the Adviser to recoup the fees foregone as a result of the existence of the hurdle rate. Thereafter, the Adviser will be entitled to receive 10.00% of the closed-end fund’s pre-incentive fee net investment income. Amounts waived by the Adviser will not be subject to recoupment from the closed-end fund.

3. The actual annualized distribution rate at listing may be higher or lower based on the then current NAV. The payment of future distributions on the fund’s common shares is subject to the discretion of the fund’s board of trustees and applicable legal restrictions and, therefore, there can be no assurance as to the amount or timing of any such future distributions

4. Income-producing investments represented 96.0% of the portfolio as of December 31, 2024, inclusive of certain common equity investments which paid special distributions to the Fund over the last twelve months. Absent these payments, however, income-accruing assets represented 92.0% off the portfolio’s fair value as of December 31, 2024.

5. There can be no assurance the Fund will successfully complete the proposed listing. If the Fund completes a listing of its common shares, shares of closed-end funds frequently trade at a price lower than their net asset value. This is commonly referred to as “trading at a discount.” This characteristic of shares of closed-end funds is a risk separate and distinct from the risk that a fund’s net asset value may decrease. Because the shares of the Fund have been illiquid, this risk may be more pronounced during the period shortly after the listing, during which the shares may experience greater volatility and may trade at significant discounts to net asset value. The fund is designed primarily for long-term investors and should not be considered a vehicle for trading purposes. Whether investors will realize a gain or loss upon the sale of the Fund’s common shares will depend upon whether the market value of the shares at the time of sale is above or below the price the investor paid, taking into account transaction costs, for the common shares and is not directly dependent upon the Fund’s net asset value. Because the market value of the Fund’s common shares will be determined by factors such as the relative demand for and supply of the common shares in the market, general market conditions and other factors beyond the control of the Fund, the Fund cannot predict whether its common stock will trade at, below or above NAV, or below or above the initial listing price for the common shares. As a result, even if the Fund does complete a listing, shareholders may not receive a return of all of their invested capital upon a sale of their shares on the exchange.
