PROSPECTUS

$150,000,000

Solar Senior Capital Ltd.

Common Stock

Debt Securities

We are an externally managed finance company. Our investment objective is to seek to maximize current income consistent with the preservation of capital. We will seek to achieve our investment objective by investing primarily in senior secured loans, including first lien, unitranche and second lien debt instruments, made to private middle-market companies whose debt is rated below investment grade, which we refer to collectively as “senior loans.” We may also invest in debt of public companies that are thinly traded. Under normal market conditions, at least 80% of the value of our net assets (including the amount of any borrowings for investment purposes) will be invested in senior loans. Securities rated below investment grade, including the senior loans we intend to target, are often referred to as “leveraged loans,” “high yield” or “junk” securities, and may be considered “high risk” compared to debt instruments that are rated above investment grade.

We were formed in December 2010 as a Maryland corporation structured as an externally managed, non-diversified closed-end management investment company. We have elected to be treated as a business development company under the Investment Company Act of 1940, or the 1940 Act. We will be managed by Solar Capital Partners, LLC. Solar Capital Management, LLC will provide the administrative services necessary for us to operate.

We may offer, from time to time, in one or more offerings or series, up to $150,000,000 of our common stock or debt securities, which we refer to, collectively, as the “securities.” The securities may be offered at prices and on terms to be described in one or more supplements to this prospectus.

In the event we offer common stock, the offering price per share of our common stock less any underwriting commissions or discounts will generally not be less than the net asset value per share of our common stock at the time we make the offering. However, we may issue shares of our common stock pursuant to this prospectus at a price per share that is less than our net asset value per share (a) with the prior approval of the majority of our common stockholders or (b) under such other circumstances as the SEC may permit.

The securities may be offered directly to one or more purchasers, or through agents designated from time to time by us, or to or through underwriters or dealers. The prospectus supplement relating to an offering will identify any agents or underwriters involved in the sale of the securities, and will disclose any applicable purchase price, fee, commission or discount arrangement between us and our agents or underwriters or among our underwriters or the basis upon which such amount may be calculated. See “Plan of Distribution.” We may not sell any of the securities through agents, underwriters or dealers without delivery of this prospectus and a prospectus supplement describing the method and terms of the offering of such securities.

Our common stock is listed on the NASDAQ Global Select Market under the symbol “SUNS.” On May 10, 2012, the last reported sales price on the NASDAQ Global Select Market for our common stock was $17.15 per share.

This prospectus, and the accompanying prospectus supplement, contains important information about us that a prospective investor should know before investing in our common stock. Please read this prospectus, and the accompanying prospectus supplement, before investing, and keep it for future reference. We are required to file annual, quarterly and current reports, proxy statements and other information about us with the Securities and Exchange Commission. This information is available free of charge by contacting us by mail at 500 Park Avenue, New York, NY 10022, by telephone at (212) 993-1670 or on our website at http://www.solarseniorcap.com . The Securities and Exchange Commission also maintains a website at http://www.sec.gov that contains such information. Information contained on our website is not incorporated by reference into this prospectus, and you should not consider that information to be part of this prospectus or the accompanying prospectus supplement.

An investment in our common stock is very risky and highly speculative. Shares of closed-end investment companies, including business development companies, frequently trade at a discount to their net asset value. In addition, the companies in which we invest are subject to special risks. See “ Risk Factors ” beginning on page 17 to read about factors you should consider, including the risk of leverage, before investing in our common stock.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

This prospectus may not be used to consummate sales of shares of common stock unless accompanied by a prospectus supplement.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we have filed with the Securities and Exchange Commission, or SEC, using the “shelf” registration process. Under the shelf registration process, which constitutes a delayed offering in reliance on Rule 415 under the Securities Act of 1933, as amended, or the Securities Act, we may offer, from time to time, in one or more offerings or series, up to $150,000,000 of our common stock or debt securities on the terms to be determined at the time of the offering. The securities may be offered at prices and on terms described in one or more supplements to this prospectus. This prospectus provides you with a general description of the securities that we may offer. Each time we use this prospectus to offer securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering. A prospectus supplement may also add, update or change information contained in this prospectus. Please carefully read this prospectus and any such supplements together with any exhibits and the additional information described under “Available Information” and in the “Summary” and “Risk Factors” sections before you make an investment decision.

FEES AND EXPENSES

The following table is intended to assist you in understanding the costs and expenses that you will bear directly or indirectly. We caution you that some of the percentages indicated in the table below are estimates and may vary. Except where the context suggests otherwise, whenever this prospectus contains a reference to fees or expenses paid by “us” or “Solar Senior Capital,” or that “we” will pay fees or expenses, you will indirectly bear such fees or expenses as an investor in Solar Senior Capital Ltd.

Example

The following example demonstrates the projected dollar amount of total cumulative expenses that would be incurred over various periods with respect to a hypothetical investment in our common stock. In calculating the following expense amounts, we have assumed that our annual operating expenses would remain at the levels set forth in the table above and have excluded performance-based incentive fees. See Note 6 below for additional information regarding certain assumptions regarding our level of leverage. In the event that shares to which this prospectus relates are sold to or through underwriters, a corresponding prospectus supplement will restate this example to reflect the applicable sales load.

The first part, which is payable quarterly in arrears, equals 20% of the excess, if any, of our “Pre-Incentive Fee Net Investment Income” that exceeds a 1.75% quarterly (7.00% annualized) hurdle rate, which we refer to as the Hurdle, subject to a “catch-up” provision measured at the end of each calendar quarter. The first part of the incentive fee is computed and paid on income that may include interest that is accrued but not yet received in cash. The operation of the first part of the incentive fee for each quarter is as follows:

13

Table of Contents

The second part of the incentive fee equals 20% of our “Incentive Fee Capital Gains,” if any, which equals our realized capital gains on a cumulative basis from inception through the end of each calendar year, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid capital gain incentive fees. The second part of the incentive fee is payable, in arrears, at the end of each calendar year (or upon termination of the Investment Advisory and Management Agreement, as of the termination date). For a more detailed discussion of the calculation of this fee, see “Investment Advisory and Management Agreement.”

The example and the expenses in the tables above should not be considered a representation of our future expenses, and actual expenses may be greater or less than those shown. While the example assumes, as required by the SEC, a 5% annual return, our performance will vary and may result in a return greater or less than 5%. The incentive fee under the Investment Advisory and Management Agreement, which, assuming a 5% annual return, would either not be payable or would have an insignificant impact on the expense amounts shown above, is not included in the example. This illustration assumes that we will not realize any capital gains (computed net of all realized capital losses and unrealized capital depreciation) in any of the indicated time periods. If we achieve sufficient returns on our investments, including through the realization of capital gains, to trigger an incentive fee of a material amount, our expenses and returns to our investors would be higher. For example, if we assumed that we received our 5% annual return completely in the form of net realized capital gains on our investments, computed net of all cumulative unrealized depreciation on our investments, the projected dollar amount of total cumulative expenses set forth in the above illustration would be as follows:

In addition, the example assumes no sales load. Also, while the example assumes reinvestment of all dividends at net asset value, participants in our dividend reinvestment plan will receive a number of shares of our common stock, determined by dividing the total dollar amount of the dividend payable to a participant by the market price per share of our common stock at the close of trading on the dividend payment date, which may be at, above or below net asset value. See “Dividend Reinvestment Plan” for additional information regarding our dividend reinvestment plan.

RISK FACTORS

Before you invest in our securities, you should be aware of various risks, including those described below. You should carefully consider these risk factors, together with all of the other information included in this prospectus, before you decide whether to make an investment in our securities. The risks set out below are not the only risks we face. If any of the following events occur, our business, financial condition and results of operations could be materially adversely affected. In such case, our net asset value and the trading price of our common stock could decline or the value of our debt securities may decline, and you may lose all or part of your investment.

Risks Related to Our Investments

We operate in a highly competitive market for investment opportunities.

A number of entities compete with us to make the types of investments that we target in leveraged companies. We compete with other BDCs, public and private funds, commercial and investment banks, commercial financing companies and, to the extent they provide an alternative form of financing, private equity funds. Many of our potential competitors are substantially larger and have considerably greater financial, technical and marketing resources than we do. For example, some competitors may have a lower cost of funds and access to funding sources that are not available to us. In addition, some of our competitors may have higher risk tolerances or different risk assessments than we do, which could allow them to consider a wider variety of investments and establish more relationships than us. Furthermore, many of our potential competitors are not subject to the regulatory restrictions that the 1940 Act imposes on us. We cannot assure you that the competitive pressures we face will not have a material adverse effect on our business, financial condition and results of operations. Also, as a result of this competition, we may not be able to take advantage of attractive investment opportunities from time to time, and we can offer no assurance that we will be able to identify and make investments that are consistent with our investment objective.

We do not seek to compete primarily based on the interest rates we offer, and we believe that some of our competitors may make loans with interest rates that may be comparable to or lower than the rates we may offer. We may lose investment opportunities if we do not match our competitors’ pricing, terms and structure. However, if we match our competitors’ pricing, terms and structure, we may experience decreased net interest income and increased risk of credit loss.

Our investments are very risky and highly speculative.

We invest primarily in senior secured loans, including first lien, unitranche and second lien debt instruments, made to middle-market companies whose debt is rated below investment grade. Securities rated below investment grade are often referred to as “leveraged loans,” “high yield” or “junk” securities, and may be considered “high risk” compared to debt instruments that are rated above investment grade.

When we make a senior secured term loan investment in a portfolio company, we generally take a security interest in the available assets of the portfolio company, including the equity interests of its subsidiaries, which we expect to help mitigate the risk that we will not be repaid. However, there is a risk that the collateral securing our loans may decrease in value over time, may be difficult to sell in a timely manner, may be difficult to appraise and may fluctuate in value based upon the success of the business and market conditions, including as a result of the inability of the portfolio company to raise additional capital, and, in some circumstances, our lien could be subordinated to claims of other creditors. In addition, deterioration in a portfolio company’s financial condition and prospects, including its inability to raise additional capital, may be accompanied by deterioration in the value of the collateral for the loan. Consequently, the fact that a loan is secured does not guarantee that we will receive principal and interest payments according to the loan’s terms, or at all, or that we will be able to collect on the loan should we be forced to enforce our remedies.

17

Table of Contents

In addition, investing in middle-market companies involves a number of significant risks, including:

The lack of liquidity in our investments may adversely affect our business.

We generally make investments in private companies. Substantially all of these securities are subject to legal and other restrictions on resale or will otherwise be less liquid than publicly traded securities. The illiquidity of our investments may make it difficult for us to sell such investments if the need arises. In addition, if we are required to liquidate all or a portion of our portfolio quickly, we may realize significantly less than the value at which we have previously recorded our investments. In addition, we may face other restrictions on our ability to liquidate an investment in a portfolio company to the extent that we have material non-public information regarding such portfolio company.

Our portfolio may be concentrated in a limited number of portfolio companies and industries, which will subject us to a risk of significant loss if any of these companies defaults on its obligations under any of its debt instruments or if there is a downturn in a particular industry.

Although we do not intend to focus our investments in any specific industries, our portfolio may be concentrated in a limited number of portfolio companies and industries. Beyond the asset diversification requirements associated with our qualification as a RIC under Subchapter M of the Code, we will not have fixed guidelines for diversification, and while we will not target any specific industries, our investments may be concentrated in relatively few industries. As a result, the aggregate returns we will realize may be significantly adversely affected if a small number of investments perform poorly or if we need to write down the value of any one investment. Additionally, a downturn in any particular industry in which we are invested could also significantly impact the aggregate returns we realize.

Capital markets have recently been in a period of disruption and instability. These market conditions have materially and adversely affected debt and equity capital markets in the United States and abroad, which may in the future have a negative impact on our business and operations.

The global capital markets have recently been in a period of disruption as evidenced by a lack of liquidity in the debt capital markets, significant write-offs in the financial services sector, the re-pricing of credit risk in the broadly syndicated credit market and the failure of certain major financial institutions. Despite actions of the

18

Table of Contents

United States federal government and foreign governments, these events contributed to worsening general economic conditions that materially and adversely impacted the broader financial and credit markets and reduced the availability of debt and equity capital for the market as a whole and financial services firms in particular. These conditions could continue for a prolonged period of time or worsen in the future. While these conditions persist, we and other companies in the financial services sector may have to access, if available, alternative markets for debt and equity capital. Equity capital may be difficult to raise because, subject to some limited exceptions which apply to us, as a BDC we are generally not able to issue additional shares of our common stock at a price less than net asset value without first obtaining approval for such issuance from our stockholders and our independent directors. At our 2012 Annual Stockholders Meeting, subject to certain determinations required to be made by our board of directors, our stockholders approved our ability to sell or otherwise issue shares of our common stock, not exceeding 25% of our then outstanding common stock immediately prior to each such offering, at a price below the then current net asset value per share during a period beginning on May 3, 2012 and expiring on the earlier of the one-year anniversary of the date of the 2012 Annual Stockholders Meeting and the date of our 2012 Annual Stockholders Meeting, which is expected to be held in May 2013. However, notwithstanding such stockholder approval, since our initial public offering on February 24, 2011, we have not sold any shares of our common stock at a price below our then current net asset value per share. In addition, our ability to incur indebtedness (including by issued preferred stock) is limited by applicable regulations such that our asset coverage, as defined in the 1940 Act, must equal at least 200% immediately after each time we incur indebtedness. The debt capital that will be available, if at all, may be at a higher cost and on less favorable terms and conditions in the future. Any inability to raise capital could have a negative effect on our business, financial condition and results of operations.

The illiquidity of our investments may make it difficult for us to sell such investments if required. As a result, we may realize significantly less than the value at which we will have recorded our investments. In addition, significant changes in the capital markets may have a negative effect on the valuations of our investments and on the potential for liquidity events involving our investments. An inability to raise capital, and any required sale of our investments for liquidity purposes, could have a material adverse impact on our business, financial condition or results of operations.

The recent downgrade of the U.S. credit rating and the economic crisis in Europe could negatively impact our business, financial condition and results of operations.

Recent U.S. debt ceiling and budget deficit concerns, together with signs of deteriorating sovereign debt conditions in Europe, have increased the possibility of additional credit-rating downgrades and economic slowdowns. Although U.S. lawmakers passed legislation to raise the federal debt ceiling, Standard & Poor’s Ratings Services lowered its long-term sovereign credit rating on the United States from “AAA” to “AA+” in August 2011. The impact of this or any further downgrades to the U.S. government’s sovereign credit rating, or its perceived creditworthiness, and the impact of the current crisis in Europe with respect to the ability of certain European Union countries to continue to service their sovereign debt obligations is inherently unpredictable and could adversely effect the U.S. and global financial markets and economic conditions. There can be no assurance that governmental or other measures to aid economic recovery will be effective. These developments, and the government’s credit concerns in general, could cause interest rates and borrowing costs to rise, which may negatively impact our ability to access the capital markets on favorable terms. In addition, the decreased credit rating could create broader financial turmoil and uncertainty, which may weigh heavily on our stock price. Continued adverse economic conditions could have a material adverse effect on our business, financial condition and results of operations.

Economic recessions or downturns could impair our portfolio companies and harm our operating results.

Many of our potential portfolio companies may be susceptible to economic slowdowns or recessions and may be unable to repay our loans during these periods. Therefore, our non-performing assets may increase and the value of our portfolio may decrease during these periods as we will be required to record the values of our investments. Adverse economic conditions also may decrease the value of collateral securing some of our loans

19

Table of Contents

and the value of our equity investments at fair value. Economic slowdowns or recessions could lead to financial losses in our portfolio and a decrease in revenues, net income and assets. Unfavorable economic conditions also could increase our funding costs, limit our access to the capital markets or result in a decision by lenders not to extend credit to us. These events could prevent us from increasing investments and harm our operating results.

A portfolio company’s failure to satisfy financial or operating covenants imposed by us or other lenders could lead to defaults and, potentially, acceleration of the time when the loans are due and foreclosure on its secured assets, which could trigger cross-defaults under other agreements and jeopardize the portfolio company’s ability to meet its obligations under the debt that we will hold. We may incur additional expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a defaulting portfolio company. In addition, if one of our portfolio companies were to go bankrupt, depending on the facts and circumstances, including the extent to which we will actually provide significant managerial assistance to that portfolio company, a bankruptcy court might recharacterize our debt holding and subordinate all or a portion of our claim to that of other creditors.

Price declines and illiquidity in the corporate debt markets may adversely affect the fair value of our portfolio investments, reducing our net asset value through increased net unrealized depreciation.

As a BDC, we are required to carry our investments at market value or, if no market value is ascertainable, at fair value as determined in good faith by or under the direction of our board of directors. Decreases in the market values or fair values of our investments will be recorded as unrealized depreciation. The unprecedented declines in prices and liquidity in the corporate debt markets from 2008 through mid-2010 have resulted in significant net unrealized depreciation in the portfolios of many existing BDCs, reducing their net asset value. Depending on market conditions, we may face similar losses, which could reduce our net asset value and have a material adverse impact on our business, financial condition and results of operations.

The effect of global climate change may impact the operations of our portfolio companies.

There may be evidence of global climate change. Climate change creates physical and financial risk and some of our portfolio companies may be adversely affected by climate change. For example, the needs of customers of energy companies vary with weather conditions, primarily temperature and humidity. To the extent weather conditions are affected by climate change, energy use could increase or decrease depending on the duration and magnitude of any changes. Increases in the cost of energy could adversely affect the cost of operations of our portfolio companies if the use of energy products or services is material to their business. A decrease in energy use due to weather changes may affect some of our portfolio companies’ financial condition, through decreased revenues. Extreme weather conditions in general require more system backup, adding to costs, and can contribute to increased system stresses, including service interruptions.

Our failure to make follow-on investments in our portfolio companies could impair the value of our portfolio.

Following an initial investment in a portfolio company, we may make additional investments in that portfolio company as “follow-on” investments, in order to: (i) increase or maintain in whole or in part our ownership percentage; (ii) exercise warrants, options or convertible securities that were acquired in the original or subsequent financing; or (iii) attempt to preserve or enhance the value of our investment. We may elect not to make follow-on investments or otherwise lack sufficient funds to make those investments. We will have the discretion to make any follow-on investments, subject to the availability of capital resources. The failure to make follow-on investments may, in some circumstances, jeopardize the continued viability of a portfolio company and our initial investment, or may result in a missed opportunity for us to increase our participation in a successful operation. Even if we have sufficient capital to make a desired follow-on investment, we may elect not to make a follow-on investment because we may not want to increase our concentration of risk, either because we will prefer other opportunities or because we will be subject to BDC requirements that would prevent such follow-on investments, or because of the desire to maintain our RIC tax status.

Table of Contents

Because we generally will not hold controlling equity interests in our portfolio companies, we may not be in a position to exercise control over our portfolio companies or to prevent decisions by management of our portfolio companies that could decrease the value of our investments.

Although we may do so in the future, initially we do not intend to hold controlling equity positions in our portfolio companies. As a result, we will be subject to the risk that a portfolio company may make business decisions with which we disagree, and that the management and/or stockholders of a portfolio company may take risks or otherwise act in ways that will be adverse to our interests. Due to the lack of liquidity of the investments that we will typically hold in our portfolio companies, we may not be able to dispose of our investments in the event we disagree with the actions of a portfolio company and may therefore suffer a decrease in the value of our investments.

An investment strategy focused primarily on privately held companies presents certain challenges, including the lack of available information about these companies, a dependence on the talents and efforts of only a few key portfolio company personnel and a greater vulnerability to economic downturns.

We invest primarily in privately held companies. Generally, little public information exists about these companies, and we will be required to rely on the ability of Solar Capital Partners’ investment professionals to obtain adequate information to evaluate the potential returns from investing in these companies. If we will be unable to uncover all material information about these companies, we may not make a fully informed investment decision, and we may lose money on our investments. Also, privately held companies frequently have less diverse product lines and smaller market presence than larger competitors. These factors could adversely affect our investment returns as compared to companies investing primarily in the securities of public companies.

Our portfolio companies may incur debt that ranks equally with, or senior to, some of our investments in such companies.

We invest primarily in senior secured loans, including unitranche, second lien, as well as unsecured debt instruments issued by our portfolio companies. If we invest in unitranche, second lien, or unsecured debt instruments, our portfolio companies typically may be permitted to incur other debt that ranks equally with, or senior to, such debt instruments. By their terms, such debt instruments may provide that the holders are entitled to receive payment of interest or principal on or before the dates on which we will be entitled to receive payments in respect of the debt securities in which we will invest. Also, in the event of insolvency, liquidation, dissolution, reorganization or bankruptcy of a portfolio company, holders of debt instruments ranking senior to our investment in that portfolio company would typically be entitled to receive payment in full before we receive any distribution in respect of our investment. In such cases, after repaying such senior creditors, such portfolio company may not have any remaining assets to use for repaying its obligation to us. In the case of debt ranking equally with debt securities in which we will invest, we would have to share on an equal basis any distributions with other creditors holding such debt in the event of an insolvency, liquidation, dissolution, reorganization or bankruptcy of the relevant portfolio company. Any such limitations on the ability of our portfolio companies to make principal or interest payments to us, if at all, may reduce our net asset value and have a negative material adverse impact to our business, financial condition and results of operation.

Our investments in foreign securities may involve significant risks in addition to the risks inherent in U.S. investments.

Our investment strategy contemplates potential investments in debt securities of foreign companies. Investing in foreign companies may expose us to additional risks not typically associated with investing in U.S. companies. These risks include changes in exchange control regulations, political and social instability, expropriation, imposition of foreign taxes, less liquid markets and less available information than is generally the case in the United States, higher transaction costs, less government supervision of exchanges, brokers and issuers, less developed bankruptcy laws, difficulty in enforcing contractual obligations, lack of uniform accounting and auditing standards and greater price volatility.

Table of Contents

Although most of our investments will be U.S. dollar-denominated, any investments denominated in a foreign currency will be subject to the risk that the value of a particular currency will change in relation to one or more other currencies. Among the factors that may affect currency values are trade balances, the level of short-term interest rates, differences in relative values of similar assets in different currencies, long-term opportunities for investment and capital appreciation, and political developments. We may employ hedging techniques to minimize these risks, but we can offer no assurance that we will, in fact, hedge currency risk, or that if we do, such strategies will be effective.

We may expose ourselves to risks if we engage in hedging transactions.

If we engage in hedging transactions, we may expose ourselves to risks associated with such transactions. We may utilize instruments such as forward contracts, currency options and interest rate swaps, caps, collars and floors to seek to hedge against fluctuations in the relative values of our portfolio positions from changes in currency exchange rates and market interest rates. Hedging against a decline in the values of our portfolio positions does not eliminate the possibility of fluctuations in the values of such positions or prevent losses if the values of such positions decline. However, such hedging can establish other positions designed to gain from those same developments, thereby offsetting the decline in the value of such portfolio positions. Such hedging transactions may also limit the opportunity for gain if the values of the underlying portfolio positions should increase. It may not be possible to hedge against an exchange rate or interest rate fluctuation that is so generally anticipated that we are not able to enter into a hedging transaction at an acceptable price. Moreover, for a variety of reasons, we may not seek to establish a perfect correlation between such hedging instruments and the portfolio holdings being hedged. Any such imperfect correlation may prevent us from achieving the intended hedge and expose us to risk of loss. In addition, it may not be possible to hedge fully or perfectly against currency fluctuations affecting the value of securities denominated in non-U.S. currencies because the value of those securities is likely to fluctuate as a result of factors not related to currency fluctuations. To the extent we engage in hedging transactions, we also face the risk that counterparties to the derivative instruments we hold may default, which may expose us to unexpected losses from positions where we believed that our risk had been appropriately hedged.

Our investment adviser may not be able to achieve the same or similar returns as those achieved by our senior investment professionals while they were employed at prior positions.

Although in the past Mr. Gross held senior positions at a number of investment firms, including Solar Capital, Apollo Investment Corporation and Apollo Management, L.P., Mr. Gross’ track record and achievements are not necessarily indicative of future results that will be achieved by our investment adviser. In his role at such other firms, Mr. Gross was part of an investment team, and he was not solely responsible for generating investment ideas. In addition, such investment teams arrived at investment decisions by consensus.

Risks Relating to an Investment in Our Securities

Our shares may trade at a substantial discount from net asset value and may continue to do so over the long term.

Shares of closed-end investment companies have frequently traded at a market price that is less than the net asset value that is attributable to those shares. The possibility that our shares of common stock will trade at a substantial discount from net asset value over the long term is separate and distinct from the risk that our net asset value will decrease. We cannot predict whether shares of our common stock will trade above, at or below our net asset value. If our common stock trades below its net asset value, we will generally not be able to issue additional shares or sell our common stock at its market price without first obtaining the approval for such issuance from our stockholders and our independent directors. At our 2012 Annual Stockholders Meeting, subject to certain determinations required to be made by our board of directors, our stockholders approved our ability to sell or otherwise issue shares of our common stock, not exceeding 25% of our then outstanding common stock immediately prior to each such offering, at a price below the then current net asset value per share

during a period beginning on May 3, 2012 and expiring on the earlier of the one-year anniversary of the date of the 2012 Annual Stockholders Meeting and the date of our 2012 Annual Stockholders Meeting, which is expected to be held in May 2013. However, notwithstanding such stockholder approval, since our initial public offering on February 24, 2011, we have not sold any shares of our common stock at a price below our then current net asset value per share. If additional funds are not available to us, we could be forced to curtail or cease our new lending and investment activities, and our net asset value could decrease and our level of distributions could be impacted.

Our common stock price may be volatile and may decrease substantially.

The trading price of our common stock may fluctuate substantially. The price of our common stock that will prevail in the market may be higher or lower than the price you pay, depending on many factors, some of which are beyond our control and may not be directly related to our operating performance. These factors include, but are not limited to, the following:

In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. Due to the potential volatility of our stock price once a market for our stock is established, we may become the target of securities litigation in the future. Securities litigation could result in substantial costs and divert management’s attention and resources from our business.

There is a risk that our stockholders may not receive distributions or that our distributions may not grow over time.

We intend to make distributions on a monthly basis to our stockholders out of assets legally available for distribution. We cannot assure you that we will achieve investment results that will allow us to make a specified level of cash distributions or year-to-year increases in cash distributions. In addition, due to the asset coverage test applicable to us as a business development company, we may be limited in our ability to make distributions.

We may choose to pay dividends in our own common stock, in which case our stockholders may be required to pay federal income taxes in excess of the cash dividends they receive.

In order to satisfy the Annual Distribution Requirement (as described under “Material U.S. Federal Income Tax Considerations”), we may distribute taxable dividends that are payable in cash or shares of our common stock at the election of each stockholder. Under certain applicable provisions of the Code and the Treasury

23

Table of Contents

regulations, distributions payable in cash or in shares of stock at the election of stockholders are treated as taxable dividends. The Internal Revenue Service has issued private rulings indicating that this rule will apply even where the total amount of cash that may be distributed is limited to no more than 20% of the total distribution. Under these rulings, if too many stockholders elect to receive their distributions in cash, each such stockholder would receive a pro rata share of the total cash to be distributed and would receive the remainder of their distribution in shares of stock. If we decide to make any distributions consistent with these rulings that are payable in part in our stock, taxable stockholders receiving such dividends will be required to include the full amount of the dividend (whether received in cash, our stock, or a combination thereof) as ordinary income (or as long-term capital gain to the extent such distribution is properly reported as a capital gain dividend) to the extent of our current and accumulated earnings and profits for United States federal income tax purposes. As a result, a U.S. stockholder may be required to pay tax with respect to such dividends in excess of any cash received. If a U.S. stockholder sells the stock it receives as a dividend in order to pay this tax, the sales proceeds may be less than the amount included in income with respect to the dividend, depending on the market price of our stock at the time of the sale. Furthermore, with respect to non-U.S. stockholders, we may be required to withhold U.S. tax with respect to such dividends, including in respect of all or a portion of such dividend that is payable in stock. In addition, if a significant number of our stockholders determine to sell shares of our stock in order to pay taxes owed on dividends, it may put downward pressure on the trading price of our stock. For a more detailed discussion, see “Material U.S. Federal Income Tax Considerations.”

Sales of substantial amounts of our common stock in the public market may have an adverse effect on the market price of our common stock.

The 500,000 shares of our common stock that were issued to Solar Senior Capital Investors LLC in the Concurrent Private Placement, pursuant to the exemption from registration provided by Section 4(2) under the Securities Act, including any shares that are attributable to such shares issued pursuant to our dividend reinvestment plan, are no longer subject to lock-up restrictions that Solar Senior Capital Investors LLC agreed to in connection with the Concurrent Private Placement, and are generally available for resale without restriction, subject to the provisions of Rule 144 promulgated under the Securities Act. Sales of substantial amounts of our common stock, or the availability of such common stock for sale, could adversely affect the prevailing market prices for our common stock. If this occurs and continues, it could impair our ability to raise additional capital through the sale of securities should we desire to do so.

We have also committed to file a registration statement to register the resale of the shares of common stock that were issued in the Concurrent Private Placement to Solar Senior Capital Investors LLC within 60 days of receiving a request from Solar Senior Capital Investors LLC to do so. We have committed to use our commercially reasonable efforts to obtain effectiveness of such registration statement as soon as reasonably practicable after the filing of such registration statement. Assuming effectiveness of such registration statement, Solar Senior Capital Investors LLC will generally be able to resell its shares of common stock without restriction.

We will have broad discretion over the use of proceeds of any offering made pursuant to this prospectus, to the extent it is successful.

We will have significant flexibility in applying the proceeds of any offering made pursuant to this prospectus. We will also pay operating expenses, and may pay other expenses such as due diligence expenses of potential new investments, from net proceeds. Our ability to achieve our investment objective may be limited to the extent that the net proceeds of the offering, pending full investment, are used to pay operating expenses. In addition, we can provide you no assurance that the current offering will be successful, or that by increasing the size of our available equity capital our aggregate expenses, and correspondingly, our expense ratio, will be lowered.

The net asset value per share of our common stock may be diluted if we sell shares of our common stock in one or more offerings at prices below the then current net asset value per share of our common stock.

At our 2012 Annual Stockholders Meeting, subject to certain determinations required to be made by our board of directors, our stockholders approved our ability to sell or otherwise issue shares of our common stock,

24

Table of Contents

not exceeding 25% of our then outstanding common stock immediately prior to each such offering, at a price below the then current net asset value per share during a period beginning on May 3, 2012 and expiring on the earlier of the one-year anniversary of the date of the 2012 Annual Stockholders Meeting and the date of our 2013 Annual Stockholders Meeting, which is expected to be held in May 2013. However, notwithstanding such stockholder approval, since our initial public offering on February 24, 2011, we have not sold any shares of our common stock at a price below our then current net asset value per share.

To the extent we receive the necessary stockholder approval, any decision to sell shares of our common stock below its then current net asset value per share would be subject to the determination by our board of directors that such issuance is in our and our stockholders’ best interests.

To the extent we receive the necessary stockholder approval, if we were to sell shares of our common stock below its then current net asset value per share, such sales would result in an immediate dilution to the net asset value per share of our common stock. This dilution would occur as a result of the sale of shares at a price below the then current net asset value per share of our common stock and a proportionately greater decrease in the stockholders’ interest in our earnings and assets and their voting interest in us than the increase in our assets resulting from such issuance. Because the number of shares of common stock that could be so issued and the timing of any issuance is not currently known, the actual dilutive effect cannot be predicted.

Further, if our current stockholders do not purchase any shares to maintain their percentage interest, regardless of whether such offering is above or below the then current net asset value per share, their voting power will be diluted. For example, if we sell an additional 10% of our common shares at a 5% discount from net asset value, a stockholder who does not participate in that offering for its proportionate interest will suffer net asset value dilution of up to 0.5% or $5 per $1000 of net asset value. For additional information and hypothetical examples of these risks, see “Sale of Common Stock Below Net Asset Value” and the prospectus supplement pursuant to which such sale is made.

Risks Relating to Our Business and Structure

We have a limited operating history.

We were formed and commenced operations in December 2010. As a result of a lack of operating history, we are subject to many of the business risks and uncertainties associated with recently formed businesses, including the risk that we will not achieve our investment objective and that the value of your investment could decline substantially.

We are dependent upon Solar Capital Partners’ key personnel for our future success.

We depend on the diligence, skill and network of business contacts of Messrs. Gross and Spohler, who serve as the managing member and a partner of Solar Capital Partners, respectively, and who lead Solar Capital Partners’ investment team. Messrs. Gross and Spohler, together with the other dedicated investment professionals available to Solar Capital Partners, evaluate, negotiate, structure, close and monitor our investments. Our future success will depend on the continued service of Messrs. Gross and Spohler and the other investment professionals available to Solar Capital Partners. We cannot assure you that unforeseen business, medical, personal or other circumstances would not lead any such individual to terminate his relationship with us. The loss of Mr. Gross or Mr. Spohler, or any of the other senior investment professionals who serve on Solar Capital Partners’ investment team, could have a material adverse effect on our ability to achieve our investment objective as well as on our financial condition and results of operations. In addition, we can offer no assurance that Solar Capital Partners will remain our investment adviser.

The senior investment professionals of Solar Capital Partners are and may in the future become affiliated with entities engaged in business activities similar to those intended to be conducted by us, and may have conflicts of interest in allocating their time. We expect that Messrs. Gross and Spohler will dedicate a significant

25

Table of Contents

portion of their time to the activities of Solar Senior Capital; however, they may be engaged in other business activities which could divert their time and attention in the future. Specifically, each of Messrs. Gross and Spohler serve as chief executive officer and chief operating officer, respectively, of Solar Capital.

Our business model depends to a significant extent upon strong referral relationships with financial sponsors, and the inability of the senior investment professionals of our investment adviser to maintain or develop these relationships, or the failure of these relationships to generate investment opportunities, could adversely affect our business.

We expect that the principals of our investment adviser will maintain and develop their relationships with financial sponsors, and we will rely to a significant extent upon these relationships to provide us with potential investment opportunities. If the senior investment professionals of our investment adviser fail to maintain their existing relationships or develop new relationships with other sponsors or sources of investment opportunities, we will not be able to grow our investment portfolio. In addition, individuals with whom the senior investment professionals of our investment adviser have relationships are not obligated to provide us with investment opportunities, and, therefore, there is no assurance that such relationships will generate investment opportunities for us.

A disruption in the capital markets and the credit markets could negatively affect our business.

As a BDC, we have to maintain our ability to raise additional capital for investment purposes. Without sufficient access to the capital markets or credit markets, we may be forced to curtail our business operations or we may not be able to pursue new business opportunities. Disruptive conditions in the financial industry and the impact of new legislation in response to those conditions could restrict our business operations and could adversely impact our results of operations and financial condition.

If the fair value of our assets declines substantially, we may fail to maintain the asset coverage ratios imposed upon us by the 1940 Act and the Credit Facility. Any such failure could result in an event of default and all of our debt being declared immediately due and payable and would affect our ability to issue senior securities, including borrowings, and pay dividends, which could materially impair our business operations. Our liquidity could be impaired further by an inability to access the capital markets. For example, we cannot be certain that we will be able to consummate new borrowing facilities to provide capital for normal operations, including new originations. Reflecting concern about the stability of the financial markets, many lenders and institutional investors have reduced or ceased providing funding to borrowers. This market turmoil and tightening of credit have led to increased market volatility and widespread reduction of business activity generally.

If we are unable to consummate new facilities on commercially reasonable terms, our liquidity will be reduced significantly. If we consummate new facilities but are then unable to repay amounts outstanding under such facilities, and are declared in default or are unable to renew or refinance these facilities, we would not be able to initiate significant originations or to operate our business in the normal course. These situations may arise due to circumstances that we may be unable to control, such as inaccessibility to the credit markets, a severe decline in the value of the U.S. dollar, a further economic downturn or an operational problem that affects third parties or us, and could materially damage our business. Moreover, we are unable to predict when economic and market conditions may become more favorable. Even if such conditions improve broadly and significantly over the long term, adverse conditions in particular sectors of the financial markets could adversely impact our business.

Our financial condition and results of operations will depend on our ability to manage future growth effectively.

Our ability to achieve our investment objective and to grow depends on Solar Capital Partners’ ability to identify, invest in and monitor companies that meet our investment criteria.

26

Table of Contents

Accomplishing this result on a cost-effective basis is largely a function of Solar Capital Partners’ structuring of the investment process, its ability to provide competent, attentive and efficient services to us and its ability to access financing for us on acceptable terms. The investment team of Solar Capital Partners has substantial responsibilities under the Investment Advisory and Management Agreement, and they may also be called upon to provide managerial assistance to our portfolio companies as the principals of our administrator. In addition, the members of Solar Capital Partners’ investment team have similar responsibilities with respect to the management of Solar Capital’s investment portfolio. Such demands on their time may distract them or slow our rate of investment. In order to grow, we and Solar Capital Partners will need to retain, train, supervise and manage new investment professionals. However, we can offer no assurance that any such investment professionals will contribute effectively to the work of the investment adviser. Any failure to manage our future growth effectively could have a material adverse effect on our business, financial condition and results of operations.

We may need to raise additional capital to grow because we must distribute most of our income.

We may need additional capital to fund growth in our investments. We expect to issue equity securities and expect to borrow from financial institutions in the future. A reduction in the availability of new capital could limit our ability to grow. We must distribute at least 90% of our investment company taxable income to our stockholders to maintain our regulated investment company status. As a result, any such cash earnings may not be available to fund investment originations. We expect to borrow from financial institutions and issue additional debt and equity securities. If we fail to obtain funds from such sources or from other sources to fund our investments, it could limit our ability to grow, which may have an adverse effect on the value of our securities. In addition, as a BDC, our ability to borrow or issue additional preferred stock may be restricted if our total assets are less than 200% of our total borrowings and preferred stock.

Any failure on our part to maintain our status as a BDC would reduce our operating flexibility and we may be limited in our investment choices as a BDC.

The 1940 Act imposes numerous constraints on the operations of BDCs. For example, BDCs are required to invest at least 70% of their total assets in specified types of “qualifying assets”, primarily in private companies or thinly-traded U.S. public companies, cash, cash equivalents, U.S. government securities and other high quality debt investments that mature in one year or less. In addition, subject to certain limited exceptions, an investment in an issuer that has outstanding securities listed on a national exchange may be treated as a qualifying asset only if such issuer has a market capitalization that is less than $250 million at the time of such investment. Furthermore, any failure to comply with the requirements imposed on BDCs by the 1940 Act could cause the SEC to bring an enforcement action against us and/or expose us to claims of private litigants. In addition, upon approval of a majority of our stockholders, we may elect to withdraw our status as a BDC. If we decide to withdraw our election, or if we otherwise fail to qualify, or maintain our qualification, as a BDC, we may be subject to the substantially greater regulation under the 1940 Act as a closed-end investment company. Compliance with such regulations would significantly decrease our operating flexibility, and could significantly increase our costs of doing business.

Regulations governing our operation as a BDC affect our ability to, and the way in which we will, raise additional capital. As a BDC, the necessity of raising additional capital may expose us to risks, including the typical risks associated with leverage.

We may issue debt securities or preferred stock and/or borrow money from banks or other financial institutions, which we refer to collectively as “senior securities,” up to the maximum amount permitted by the 1940 Act. Under the provisions of the 1940 Act, we are permitted, as a BDC, to issue senior securities in amounts such that our asset coverage ratio, as defined in the 1940 Act, equals at least 200% of gross assets less all liabilities and indebtedness not represented by senior securities, after each issuance of senior securities. If the value of our assets declines, we may be unable to satisfy this test. If that happens, we may be required to sell a portion of our investments and, depending on the nature of our leverage, repay a portion of our indebtedness at a

27

Table of Contents

time when such sales may be disadvantageous. Also, any amounts that we use to service our indebtedness would not be available for distributions to our common stockholders. Furthermore, as a result of issuing senior securities, we would also be exposed to typical risks associated with leverage, including an increased risk of loss.

As of March 31, 2012, we had $18.2 million outstanding under the Credit Facility. If we issue preferred stock, the preferred stock would rank “senior” to common stock in our capital structure, preferred stockholders would have separate voting rights on certain matters and might have other rights, preferences, or privileges more favorable than those of our common stockholders, and the issuance of preferred stock could have the effect of delaying, deferring or preventing a transaction or a change of control that might involve a premium price for holders of our common stock or otherwise be in your best interest.

We are not generally able to issue and sell our common stock at a price below net asset value per share. We may, however, sell our common stock, or warrants, options or rights to acquire our common stock, at a price below the then-current net asset value per share of our common stock if our board of directors determines that such sale is in the best interests of Solar Senior Capital and its stockholders, and our stockholders approve such sale. In any such case, the price at which our securities are to be issued and sold may not be less than a price that, in the determination of our board of directors, closely approximates the market value of such securities (less any distributing commission or discount). If our common stock trades at a discount to net asset value, this restriction could adversely affect our ability to raise capital. If we raise additional funds by issuing more common stock or senior securities convertible into, or exchangeable for, our common stock, then the percentage ownership of our stockholders at that time will decrease, and you might experience dilution.

At our 2012 Annual Stockholders Meeting, subject to certain determinations required to be made by our board of directors, our stockholders approved our ability to sell or otherwise issue shares of our common stock, not exceeding 25% of our then outstanding common stock immediately prior to each such offering, at a price below the then current net asset value per share during a period beginning on May 3, 2012 and expiring on the earlier of the one-year anniversary of the date of the 2012 Annual Stockholders Meeting and the date of our 2013 Annual Stockholders Meeting, which is expected to be held in May 2013.

We may borrow money, which would magnify the potential for gain or loss on amounts invested and may increase the risk of investing in us.

The use of leverage magnifies the potential for gain or loss on amounts invested and, therefore, increases the risks associated with investing in our securities. As of December 31, 2011, we had $8.6 million outstanding under the Cedit Facility. We may borrow from and issue senior debt securities to banks, insurance companies and other lenders in the future. Lenders of these senior securities, including the Credit Facility, will have fixed dollar claims on our assets that are superior to the claims of our common stockholders, and we would expect such lenders to seek recovery against our assets in the event of a default. If the value of our assets decreases, leveraging would cause net asset value to decline more sharply than it otherwise would have had we not leveraged. Similarly, any decrease in our income would cause net income to decline more sharply than it would have had we not borrowed. Such a decline could also negatively affect our ability to make dividend payments on our common stock. Leverage is generally considered a speculative investment technique. Our ability to service any debt that we incur will depend largely on our financial performance and will be subject to prevailing economic conditions and competitive pressures. Moreover, as the management fee payable to our investment adviser, Solar Capital Partners, will be payable based on our gross assets, including those assets acquired through the use of leverage, Solar Capital Partners will have a financial incentive to incur leverage which may not be consistent with our stockholders’ interests. In addition, our common stockholders will bear the burden of any increase in our expenses as a result of leverage, including any increase in the management fee payable to Solar Capital Partners.

As a BDC, we generally are required to meet a coverage ratio of total assets to total borrowings and other senior securities, which include all of our borrowings and any preferred stock that we may issue in the future, of

28

Table of Contents

at least 200%. Additionally, the Credit Facility requires us to comply with certain financial and other restriction covenant including maintaining an asset coverage ratio of less than 200% at any time. Failure to maintain compliance with these covenants could result in an event of default and all of our debt being declared immediately due and payable. If this ratio declines below 200%, we may not be able to incur additional debt and could be required by law to sell a portion of our investments to repay some debt when it is disadvantageous to do so, which could have a material adverse effect on our operations, and we may not be able to make distributions. The amount of leverage that we employ will depend on our investment adviser’s and our board of directors’ assessment of market and other factors at the time of any proposed borrowing. We cannot assure you that we will be able to obtain credit at all or on terms acceptable to us.

In addition, the Credit Facility, and any other debt facility into which we may enter would likely impose financial and operating covenants that restrict our business activities, including limitations that could hinder our ability to finance additional loans and investments or to make the distributions required to maintain our status as a RIC under Subchapter M of the Code.

The debt securities that we may issue will be governed by an indenture or other instrument containing covenants restricting our operating flexibility. We, and indirectly our stockholders, bear the cost of issuing and servicing such debt securities. Any convertible or exchangeable securities that we issue in the future may have rights, preferences and privileges more favorable than those of our common stock.

Illustration.     The following table illustrates the effect of leverage on returns from an investment in our common stock assuming various annual returns on the portfolio, net of expenses. The calculations in the table below are hypothetical and actual returns may be higher or lower than those appearing in the table below.

To the extent we use debt or preferred stock to finance our investments, changes in interest rates will affect our cost of capital and net investment income.

To the extent we borrow money, or issue preferred stock, to make investments, our net investment income will depend, in part, upon the difference between the rate at which we borrow funds or pay dividends on preferred stock and the rate at which we invest those funds. As a result, we can offer no assurance that a significant change in market interest rates will not have a material adverse effect on our net investment income in the event we use debt to finance our investments. In periods of rising interest rates, our cost of funds would increase, except to the extent we issue fixed rate debt or preferred stock, which could reduce our net investment income. We expect that our long-term fixed-rate investments will be financed primarily with equity and long-term debt. We may use interest rate risk management techniques in an effort to limit our exposure to interest rate fluctuations. Such techniques may include various interest rate hedging activities to the extent permitted by the 1940 Act.

You should also be aware that a rise in the general level of interest rates can be expected to lead to higher interest rates applicable to our debt investments. Accordingly, an increase in interest rates would make it easier for us to meet or exceed the incentive fee hurdle rate and may result in a substantial increase of the amount of incentive fees payable to our investment adviser with respect to our pre-incentive fee net investment income.

29

Table of Contents

As of March 31, 2012, we had $18.2 million outstanding under the Credit Facility.

We may in the future determine to fund a portion of our investments with preferred stock, which would magnify the potential for gain or loss and the risks of investing in us in the same way as our borrowings.

Preferred stock, which is another form of leverage, has the same risks to our common stockholders as borrowings because the dividends on any preferred stock we issue must be cumulative. Payment of such dividends and repayment of the liquidation preference of such preferred stock must take preference over any dividends or other payments to our common stockholders, and preferred stockholders are not subject to any of our expenses or losses and are not entitled to participate in any income or appreciation in excess of their stated preference.

There will be uncertainty as to the value of our portfolio investments.

A large percentage of our portfolio investments are in the form of securities that are not publicly traded. The fair value of securities and other investments that are not publicly traded may not be readily determinable. We value these securities and the Credit Facility on a quarterly basis in accordance with our valuation policy, which is at all times consistent with U.S. generally accepted accounting policies (“GAAP”). Our board of directors may utilize the services of third-party valuation firms to aid it in determining the fair value of these securities and the Credit Facility. The board of directors discusses valuations and determines the fair value in good faith based on the input of our investment adviser and the respective third-party valuation firms. The factors that may be considered in fair value pricing our investments include the nature and realizable value of any collateral, the portfolio company’s ability to make payments and its earnings, the markets in which the portfolio company does business, comparisons to publicly traded companies, discounted cash flow and other relevant factors. Because such valuations, and particularly valuations of private securities and private companies, are inherently uncertain, may fluctuate over short periods of time and may be based on estimates, our determinations of fair value may differ materially from the values that would have been used if a ready market for these securities existed. Our net asset value could be adversely affected if our determinations regarding the fair value of our investments were materially higher than the values that we ultimately realize upon the disposal of such securities.

We may experience fluctuations in our quarterly results.

We could experience fluctuations in our quarterly operating results due to a number of factors, including the interest rate payable on the debt securities we acquire, the default rate on such securities, the level of our expenses, variations in and the timing of the recognition of realized and unrealized gains or losses, the degree to which we encounter competition in our markets and general economic conditions. As a result of these factors, results for any period should not be relied upon as being indicative of performance in future periods.

There are significant potential conflicts of interest, including Solar Capital Partners’ management of Solar Capital, which could impact our investment returns; you will not be purchasing an investment in Solar Capital.

Our executive officers and directors, as well as the current and future partners of our investment adviser, Solar Capital Partners, may serve as officers, directors or principals of entities that operate in the same or a related line of business as we do. Currently, the executive officers and directors, as well as the current partners of our investment adviser, Solar Capital Partners, serve as officers and directors of Solar Capital, a publicly-traded BDC. Accordingly, they may have obligations to investors in those entities, including to investors of Solar Capital, the fulfillment of which obligations might not be in the best interests of us or our stockholders. In addition, we note that any affiliated investment vehicle currently existing, or formed in the future, and managed by our investment adviser or its affiliates may, notwithstanding different stated investment objectives, have overlapping investment objectives with our own and, accordingly, may invest in asset classes similar to those targeted by us. As a result, Solar Capital Partners may face conflicts in allocating investment opportunities between us and such other entities. Although Solar Capital Partners will endeavor to allocate investment opportunities in a fair and equitable manner, it is possible that, in the future, we may not be given the opportunity

30

Table of Contents

to participate in investments made by investment funds managed by our investment adviser or an investment manager affiliated with our investment adviser. In any such case, when Solar Capital Partners identifies an investment, it will be forced to choose which investment fund should make the investment.

We may co-invest on a concurrent basis with Solar Capital, and any other affiliates that our investment adviser forms in the future, subject to compliance with applicable regulations and regulatory guidance and our allocation procedures. In certain circumstances, negotiated co-investments may be made only if we receive an order from the SEC permitting us to do so. There can be no assurance that any such order will be obtained.

In the course of our investing activities, we pay management and incentive fees to Solar Capital Partners and reimburse Solar Capital Partners for certain expenses it incurs. As a result, investors in our common stock will invest on a “gross” basis and receive distributions on a “net” basis after expenses, resulting in a lower rate of return than an investor might achieve through direct investments. Accordingly, there may be times when the management team of Solar Capital Partners has interests that differ from those of our stockholders, giving rise to a conflict.

We have entered into a royalty-free license agreement with our investment adviser, pursuant to which our investment adviser has granted us a non-exclusive license to use the name “Solar Senior Capital.” Under the License Agreement, we have the right to use the “Solar Senior Capital” name for so long as Solar Capital Partners or one of its affiliates remains our investment adviser. In addition, we pay Solar Capital Management, an affiliate of Solar Capital Partners, our allocable portion of overhead and other expenses incurred by Solar Capital Management in performing its obligations under the Administration Agreement, including rent, the fees and expenses associated with performing compliance functions, and our allocable portion of the compensation of our chief financial officer and any administrative support staff. These arrangements create conflicts of interest that our board of directors must monitor.

We may be obligated to pay our investment adviser incentive compensation even if we incur a loss.

Our investment adviser will be entitled to incentive compensation for each fiscal quarter in an amount equal to a percentage of the excess of our pre-incentive fee net investment income for that quarter (before deducting incentive compensation) above a performance threshold for that quarter. Accordingly, since the performance threshold is based on a percentage of our net asset value, decreases in our net asset value make it easier to achieve the performance threshold. Our pre-incentive fee net investment income for incentive compensation purposes excludes realized and unrealized capital losses or depreciation that we may incur in the fiscal quarter, even if such capital losses or depreciation result in a net loss on our statement of operations for that quarter. Thus, we may be required to pay Solar Capital Partners incentive compensation for a fiscal quarter even if there is a decline in the value of our portfolio or we incur a net loss for that quarter.

Our incentive fee may induce Solar Capital Partners to pursue speculative investments.

The incentive fee payable by us to Solar Capital Partners may create an incentive for Solar Capital Partners to pursue investments on our behalf that are riskier or more speculative than would be the case in the absence of such compensation arrangement. The incentive fee payable to our investment adviser is calculated based on a percentage of our return on invested capital. This may encourage our investment adviser to use leverage to increase the return on our investments. Under certain circumstances, the use of leverage may increase the likelihood of default, which would impair the value of our common stock. In addition, the investment adviser receives the incentive fee based, in part, upon net capital gains realized on our investments. Unlike that portion of the incentive fee based on income, there is no hurdle rate applicable to the portion of the incentive fee based on net capital gains. As a result, the investment adviser may have a tendency to invest more capital in investments that are likely to result in capital gains as compared to income producing securities. Such a practice could result in our investing in more speculative securities than would otherwise be the case, which could result in higher investment losses, particularly during economic downturns.

31

The incentive fee payable by us to our investment adviser also may induce Solar Capital Partners to invest on our behalf in instruments that have a deferred interest feature, even if such deferred payments would not provide cash necessary to enable us to pay current distributions to our shareholders. Under these investments, we would accrue interest over the life of the investment but would not receive the cash income from the investment until the end of the term. Our net investment income used to calculate the income portion of our investment fee, however, includes accrued interest. Thus, a portion of this incentive fee would be based on income that we have not yet received in cash. In addition, the “catch-up” portion of the incentive fee may encourage Solar Capital Partners to accelerate or defer interest payable by portfolio companies from one calendar quarter to another, potentially resulting in fluctuations in timing and dividend amounts.

We may invest, to the extent permitted by law, in the securities and instruments of other investment companies, including private funds, and, to the extent we so invest, will bear our ratable share of any such investment company’s expenses, including management and performance fees. We will also remain obligated to pay management and incentive fees to Solar Capital Partners with respect to the assets invested in the securities and instruments of other investment companies. With respect to each of these investments, each of our stockholders will bear his or her share of the management and incentive fee of Solar Capital Partners as well as indirectly bearing the management and performance fees and other expenses of any investment companies in which we invest.

We will become subject to corporate-level income tax if we are unable to qualify and maintain our qualification as a RIC under Subchapter M of the Code.

Although we intend to elect to be treated as a RIC under Subchapter M of the Code for 2011 and succeeding tax years, no assurance can be given that we will be able to qualify for and maintain RIC status. To obtain and maintain RIC tax treatment under the Code, we must meet the following annual distribution, income source and asset diversification requirements.

If we fail to qualify for RIC tax treatment for any reason and remain or become subject to corporate-level income tax, the resulting corporate-level taxes could substantially reduce our net assets, the amount of income available for distribution and the amount of our distributions.

We may have difficulty satisfying the annual distribution requirement in order to qualify and maintain RIC status if we recognize income before or without receiving cash representing such income.

For U.S. federal income tax purposes, we will include in income certain amounts that we have not yet received in cash, such as original issue discount, which may arise, for example, if we receive warrants in

connection with the making of a loan, or “payment in kind,” or PIK, interest, which represents contractual interest added to the loan balance and due at the end of the loan term. We also may be required to include in income certain other amounts that we will not receive in cash.

Because in certain cases we may recognize income before or without receiving cash representing such income, we may have difficulty satisfying the annual distribution requirement applicable to RICs. Accordingly, we may have to sell some of our investments at times we would not consider advantageous, raise additional debt or equity capital or reduce new investments to meet these distribution requirements. If we are not able to obtain cash from other sources, we may fail to qualify for RIC tax treatment and thus be subject to corporate-level income tax. See “Material U.S. Federal Income Tax Considerations.”

Our board of directors is authorized to reclassify any unissued shares of common stock into one or more classes of preferred stock, which could convey special rights and privileges to its owners.

Under Maryland General Corporation Law and our charter, our board of directors is authorized to classify and reclassify any authorized but unissued shares of stock into one or more classes of stock, including preferred stock. Prior to issuance of shares of each class or series, the board of directors is required by Maryland law and our charter to set the terms, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption for each class or series. Thus, the board of directors could authorize the issuance of shares of preferred stock with terms and conditions which could have the effect of delaying, deferring or preventing a transaction or a change in control that might involve a premium price for holders of our common stock or otherwise be in their best interest. The cost of any such reclassification would be borne by our existing common stockholders. Certain matters under the 1940 Act require the separate vote of the holders of any issued and outstanding preferred stock. For example, holders of preferred stock would vote separately from the holders of common stock on a proposal to cease operations as a BDC. In addition, the 1940 Act provides that holders of preferred stock are entitled to vote separately from holders of common stock to elect two preferred stock directors. We have no immediate plans to issue preferred stock. The issuance of preferred shares convertible into shares of common stock might also reduce the net income and net asset value per share of our common stock upon conversion, provided, that we will only be permitted to issue such convertible preferred stock to the extent we comply with the requirements of Section 61 of the 1940 Act, including obtaining common stockholder approval. These effects, among others, could have an adverse effect on your investment in our common stock.

Provisions of the Maryland General Corporation Law and of our charter and bylaws could deter takeover attempts and have an adverse impact on the price of our common stock.

The Maryland General Corporation Law and our charter and bylaws contain provisions that may discourage, delay or make more difficult a change in control of Solar Senior Capital or the removal of our directors. We are subject to the Maryland Business Combination Act, subject to any applicable requirements of the 1940 Act. Our board of directors has adopted a resolution exempting from the Maryland Business Combination Act any business combination between us and any other person, subject to prior approval of such business combination by our board, including approval by a majority of our disinterested directors. If the resolution exempting business combinations is repealed or our board does not approve a business combination, the Maryland Business Combination Act may discourage third parties from trying to acquire control of us and increase the difficulty of consummating such an offer. Our bylaws exempt from the Maryland Control Share Acquisition Act acquisitions of our stock by any person. If we amend our bylaws to repeal the exemption from the Maryland Control Share Acquisition Act, the Maryland Control Share Acquisition Act also may make it more difficult for a third party to obtain control of us and increase the difficulty of consummating such a transaction. However, we will amend our bylaws to be subject to the Maryland Control Share Act only if our board of directors determines that it would be in our best interests and if the SEC staff does not object to our determination that our being subject to the Maryland Control Share Act does not conflict with the 1940 Act. The SEC staff has issued informal guidance setting forth its position that certain provisions of the Maryland Control Share Act would, if implemented, violate Section 18(i) of the 1940 Act.

33

Table of Contents

We have also adopted measures that may make it difficult for a third party to obtain control of us, including provisions of our charter classifying our board of directors in three classes serving staggered three-year terms, and authorizing our board of directors to classify or reclassify shares of our stock in one or more classes or series, to cause the issuance of additional shares of our stock, to amend our charter without stockholder approval and to increase or decrease the number of shares of stock that we have authority to issue. These provisions, as well as other provisions of our charter and bylaws, may delay, defer or prevent a transaction or a change in control that might otherwise be in the best interests of our stockholders.

Our board of directors may change our investment objective, operating policies and strategies without prior notice or stockholder approval.

Our board of directors has the authority to modify or waive certain of our operating policies and strategies without prior notice (except as required by the 1940 Act) and without stockholder approval. However, absent stockholder approval, we may not change the nature of our business so as to cease to be, or withdraw our election as, a BDC. We cannot predict the effect any changes to our current operating policies and strategies would have on our business, operating results and value of our stock. Nevertheless, the effects may adversely affect our business and impact our ability to make distributions.

The impact of recent financial reform legislation on us is uncertain.

In light of recent conditions in the U.S. and global financial markets and the U.S. and global economy, legislators, the presidential administration and regulators have increased their focus on the regulation of the financial services industry. The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Reform Act”) became effective on July 21, 2010, although many provisions of the Dodd-Frank Reform Act have delayed effectiveness or will not become effective until the relevant federal agencies issue new rules to implement the Dodd-Frank Reform Act. Nevertheless, the Dodd-Frank Reform Act may have a material adverse impact on the financial services industry as a whole and on our business, results of operations and financial condition. Accordingly, we cannot predict the effect the Dodd-Frank Act or its implementing regulations will have on our business, results of operations or financial condition.

Changes in laws or regulations governing our operations may adversely affect our business.

We and our portfolio companies are subject to regulation by laws at the local, state and federal levels. These laws and regulations, as well as their interpretation, may be changed from time to time. Accordingly, any change in these laws or regulations could have a material adverse affect on our business.

Our investment adviser can resign upon 60 days’ notice, and we may not be able to find a suitable replacement within that time, resulting in a disruption in our operations that could adversely affect our financial condition, business and results of operations.

Our investment adviser has the right, under the Investment Advisory and Management Agreement, to resign at any time upon 60 days’ written notice, whether we have found a replacement or not. If our investment adviser resigns, we may not be able to find a new investment adviser or hire internal management with similar expertise and ability to provide the same or equivalent services on acceptable terms within 60 days, or at all. If we are unable to do so quickly, our operations are likely to experience a disruption, our financial condition, business and results of operations as well as our ability to pay distributions are likely to be adversely affected and the market price of our shares may decline. In addition, the coordination of our internal management and investment activities is likely to suffer if we are unable to identify and reach an agreement with a single institution or group of executives having the expertise possessed by our investment adviser and its affiliates. Even if we are able to retain comparable management, whether internal or external, the integration of such management and their lack of familiarity with our investment objective may result in additional costs and time delays that may adversely affect our financial condition, business and results of operations.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains forward-looking statements that involve substantial risks and uncertainties. These forward-looking statements are not historical facts, but rather are based on current expectations, estimates and projections about Solar Senior Capital, our current and prospective portfolio investments, our industry, our beliefs, and our assumptions. Words such as “anticipates,” “expects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “would,” “should,” “targets,” “projects,” and variations of these words and similar expressions are intended to identify forward-looking statements.

The forward-looking statements contained in this prospectus involve risks and uncertainties, including statements as to:

These statements are not guarantees of future performance and are subject to risks, uncertainties, and other factors, some of which are beyond our control and difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements, including without limitation:

Although we believe that the assumptions on which these forward-looking statements are based are reasonable, any of those assumptions could prove to be inaccurate, and as a result, the forward-looking statements based on those assumptions also could be inaccurate. Important assumptions include our ability to originate new loans and investments, certain margins and levels of profitability and the availability of additional capital. In light of these and other uncertainties, the inclusion of a projection or forward-looking statement in this prospectus should not be regarded as a representation by us that our plans and objectives will be achieved. These risks and uncertainties include those described or identified in “Risk Factors” and elsewhere in this prospectus. You should not place undue reliance on these forward-looking statements, which apply only as of the date of this prospectus. However, we will update this prospectus to reflect any material changes to the information contained herein. The forward-looking statements and projections contained in this prospectus are excluded from the safe harbor protection provided by Section 27A of the Securities Act.

USE OF PROCEEDS

We intend to use the net proceeds from the sale of our securities pursuant to this prospectus for general corporate purposes, which may include investing in debt or equity securities consistent with our investment objective, repayment of outstanding indebtedness, acquisitions and other general corporate purposes. We are continuously identifying, reviewing and, to the extent consistent with our investment objective, funding new investments. As a result, we typically raise capital as we deem appropriate to fund such new investments. The supplement to this prospectus relating to an offering will more fully identify the use of the proceeds from such offering.

We estimate that it will take three to six months for us to substantially invest the net proceeds of any offering made pursuant to this prospectus, depending on the availability of attractive opportunities and market conditions. However, we can offer no assurance that we will be able to achieve this goal. We expect that it may take more than three months to invest all of the proceeds of this offering, in part because investments in private companies often require substantial prior research and due diligence.

Pending these uses, we will invest such net proceeds primarily in cash, cash equivalents, and U.S. government securities and other high-quality debt investments that mature in one year or less from the date of investment. The management fee payable by us to our investment adviser will not be reduced while our assets are invested in such securities.

PRICE RANGE OF COMMON STOCK AND DISTRIBUTIONS

Our common stock is traded on the NASDAQ Global Select Market under the symbol “SUNS”. The following table sets forth, for each fiscal quarter since our initial public offering on February 24, 2011, the net asset value (“NAV”) per share of our common stock, the high and low intraday sales prices for our common stock, such sales prices as a percentage of NAV per share and quarterly distributions per share.

On May 10, 2012, the last reported sales price of our common stock was $17.15 per share. As of May 10, 2012, we had 3 shareholders of record.

Shares of business development companies may trade at a market price that is less than the value of the net assets attributable to those shares. The possibility that our shares of common stock will trade at a discount from net asset value or at premiums that are unsustainable over the long term are separate and distinct from the risk that our net asset value will decrease. Since our initial public offering on February 24, 2011, our shares of common stock have traded at both a discount and a premium to the net assets attributable to those shares. As of May 10, 2012, our shares of common stock traded at a discount equal to approximately 7.0% of the net assets attributable to those shares based upon our net asset value as of March 31, 2012. It is not possible to predict whether the shares offered hereby will trade at, above, or below net asset value.

We intend to distribute monthly dividends to our stockholders. Our monthly dividends, if any, will be determined by our board of directors.

37

Table of Contents

The following table reflects the cash distributions, including dividends and returns of capital, if any, per share that we have declared on our common stock since our initial public offering.:

Tax characteristics of all dividends will be reported to shareholders on Form 1099 after the end of the calendar year. Our monthly dividends, if any, will be determined by our board of directors.

We intend to elect to be taxed as a RIC under Subchapter M of the Code. To obtain and maintain our RIC status, we must distribute at least 90% of our ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any, out of the assets legally available for distribution. In addition, although we currently intend to distribute realized net capital gains ( i.e. , net long-term capital gains in excess of short-term capital losses), if any, at least annually, out of the assets legally available for such distributions, we may in the future decide to retain such capital gains for investment.

We maintain an “opt out” dividend reinvestment plan for our common stockholders. As a result, if we declare a dividend, then stockholders’ cash dividends will be automatically reinvested in additional shares of our common stock, unless they specifically “opt out” of the dividend reinvestment plan so as to receive cash dividends.

We may not be able to achieve operating results that will allow us to make dividends and distributions at a specific level or to increase the amount of these dividends and distributions from time to time. In addition, we may be limited in our ability to make dividends and distributions due to the asset coverage test for borrowings when applicable to us as a BDC under the 1940 Act and due to provisions in current and future credit facilities. If we do not distribute a certain percentage of our income annually, we will suffer adverse tax consequences, including possible loss of our RIC status. We cannot assure stockholders that they will receive any dividends and distributions or dividends and distributions at a particular level.

All dividends declared in cash payable to stockholders that are participants in our dividend reinvestment plan are generally automatically reinvested in shares of our common stock. As a result, stockholders that do not participate in the dividend reinvestment plan may experience dilution over time. Stockholders who do not elect to receive dividends in shares of common stock may experience accretion to the net asset value of their shares if our shares are trading at a premium and dilution if our shares are trading at a discount. The level of accretion or discount would depend on various factors, including the proportion of our stockholders who participate in the plan, the level of premium or discount at which our shares are trading and the amount of the dividend payable to a stockholder.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The information contained in this section should be read in conjunction with the Selected Financial and Other Data and our Financial Statements and notes thereto appearing elsewhere in this prospectus.

Overview

Solar Senior Capital Ltd., a Maryland corporation formed in December 2010, is a closed-end, externally managed, non-diversified management investment company that has elected to be treated as a BDC under the 1940 Act. In addition, for tax purposes we intend to elect to be treated as a RIC under Subchapter M of the Code.

On February 24, 2011, we priced our IPO, selling 9.0 million shares of our common stock, including the underwriters’ over-allotment, at a price of $20.00 per share. Concurrent with this offering, management purchased an additional 500,000 shares of our common stock through a Concurrent Private Placement, also at $20.00 per share.

On August 26, 2011, we established the $200 million Credit Facility with Citigroup Global Markets Inc. acting as administrative agent. In connection with the Credit Facility, our wholly-owned subsidiary, SUNS SPV LLC was formed. The Credit Facility matures on August 26, 2016 and generally bears interest at a rate of LIBOR plus 2.25%. Under the Credit Facility, $150 million will be available initially with an additional $50 million available as a delayed draw. The Credit Facility can also be expanded up to $600 million. The Credit Facility is secured by all of the assets held by the SPV. Under the Credit Facility, Solar Senior and the SPV, as applicable, have made certain customary representations and warranties, and are required to comply with various covenants, including leverage restrictions, reporting requirements and other customary requirements for similar credit facilities. The Credit Facility includes usual and customary events of default for credit facilities of this nature.

We invest primarily in U.S. middle market companies, where we believe the supply of primary capital is limited and the investment opportunities are most attractive. Our investment objective is to seek to maximize current income consistent with the preservation of capital. We seek to achieve our investment objective by investing primarily in senior loans, including first lien, unitranche, and second lien debt instruments, made to private middle-market companies whose debt is rated below investment grade, which we refer to collectively as “senior loans.” We may also invest in debt of public companies that are thinly traded. Under normal market conditions, at least 80% of the value of our net assets (including the amount of any borrowings for investment purposes) will be invested in senior loans. Senior loans typically pay interest at rates which are determined periodically on the basis of a floating base lending rate, primarily LIBOR, plus a premium. Senior loans in which we expect to invest are typically made to U.S. and, to a limited extent, non-U.S. corporations, partnerships and other business entities which operate in various industries and geographical regions. Senior loans typically are rated below investment grade. Securities rated below investment grade are often referred to as “leveraged loans,” “high yield” or “junk” securities, and may be considered “high risk” compared to debt instruments that are rated above investment grade.

We expect to invest in senior loans made primarily to private leveraged middle-market companies with approximately $20 million to $60 million of EBITDA. Our business model is focused primarily on the direct origination of investments through portfolio companies or their financial sponsors. We expect that our investments will generally range between $5 million and $30 million each, although we expect that this investment size will vary proportionately with the size of our capital base. In addition, we may invest a portion of our portfolio in other types of investments, which we refer to as opportunistic investments, which are not our primary focus but are intended to enhance our overall returns. These opportunistic investments may include, but are not limited to, direct investments in public companies that are not thinly traded and securities of leveraged companies located in select countries outside of the United States. We may invest up to 30% of our total assets in such opportunistic investments, including senior loans issued by non-U.S. issuers, subject to compliance with our regulatory obligations as a BDC under the 1940 Act.

39

Table of Contents

As of March 31, 2012, our long-term investments totaled approximately $215.0 million and our net asset value was approximately $175.3 million. Our portfolio was comprised of debt investments in 26 portfolio companies and our income producing assets, which represented 100% of our total portfolio, had a weighted average annualized yield on a fair value basis of approximately 8.2%.

Recent Developments

On May 1, 2012, our board of directors declared a monthly dividend of $0.10 per share payable on June 4, 2012 to holders of record as of May 18, 2012. We expect the dividend to be paid from taxable earnings with specific tax characteristics reported to stockholders after the end of the calendar year.

Critical Accounting Policies

The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the periods reported. Actual results could materially differ from those estimates. We have identified the following items as critical accounting policies.

Valuation of Portfolio Investments

We conduct the valuation of our assets, pursuant to which our net asset value is determined, at all times consistent with GAAP, and the 1940 Act. Our valuation procedures are set forth in more detail below:

Securities for which market quotations are readily available on an exchange are valued at the closing price on the valuation date. We may also obtain quotes with respect to certain of our investments from pricing services or brokers or dealers in order to value assets. When doing so, we determine whether the quote obtained is sufficient according to GAAP to determine the fair value of the security. If determined adequate, we use the quote obtained.

Securities for which reliable market quotations are not readily available or for which the pricing sources do not provide a valuation or methodology or provide a valuation or methodology that, in the judgment of Solar Capital Partners, or our board of directors, does not represent fair value, shall each be valued as follows: (i) each portfolio company or investment is initially valued by the investment professionals responsible for the portfolio investment; (ii) preliminary valuation conclusions are documented and discussed with senior management; (iii) independent third-party valuation firms engaged by, or on behalf of, the board of directors will conduct independent appraisals and review management’s preliminary valuations and make their own assessment for (a) each portfolio investment that, when taken together with all other investments in the same portfolio company, exceeds 10% of total assets, plus available borrowings, as of the end of the most recently completed fiscal quarter, and (b) each portfolio investment that is presently in default; and (iv) the board of directors will discuss valuations and determine the fair value of each investment in our portfolio in good faith based on the input of the investment adviser and, where appropriate, the respective third-party valuation firms.

The recommendation of fair value will generally be based on the following factors, as relevant:

40

Table of Contents

Securities for which market quotations are not readily available or for which a pricing source is not sufficient may include, but are not limited to, the following:

Determination of fair value involves subjective judgments and estimates. Accordingly, the notes to our financial statements express the uncertainty with respect to the possible effect of such valuations, and any change in such valuations, on our financial statements.

GAAP fair value measurement guidance classifies the inputs used to measure these fair values into the following hierarchy:

Level 1. Financial assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market that we have the ability to access (examples include active exchange-traded equity securities and exchange-traded derivatives).

Level 2.  Financial assets and liabilities whose values are based on quoted prices in markets that are not active or model inputs that are observable either directly or indirectly for substantially the full term of the asset or liability. Level 2 inputs include the following:

Level 3.  Financial assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect management’s own assumptions about the assumptions a market participant would use in pricing the asset or liability (examples include certain of our private debt and equity investments) and long-dated or complex derivatives (including certain equity and currency derivatives).

The following table shows the level of our investments and Credit Facility as of March 31, 2012 and December 31, 2011;

41

Table of Contents

There were no investments transferred into or out of Level 1, 2, or 3 during the three months ended March 31, 2012 and the period January 28, 2011 to December 31, 2011.

The significant unobservable quantitative inputs typically used in the fair value measurement of the Company’s Level 3 investments include current market yields as indicated by comparable publicly traded investments and loan indices, EBITDA multiples as indicated by current, comparable market transactions and quotes from brokers (see table below).

The ranges of unobservable inputs used in the fair value measurement of the Company’s Level 3 investments as of March 31, 2012 were as follows:

Significant increases or decreases in any of the above inputs in isolation would result in a significantly lower or higher fair value measurement.

Credit Facility

The Company has made an irrevocable election to apply the fair value option of accounting to the Credit Facility, in accordance with ASC 825-10. Accounting for the Credit Facility at fair value will better align the measurement methodologies of assets and liabilities, which may mitigate certain earnings volatility. As a result of this election, approximately $2.82 million of costs related to the establishment of the Credit Facility have been expensed through March 31, 2012, rather than being deferred and amortized over the life of the Credit Facility. For the three-month period ended March 31, 2012, and the period from February 28, 2011 to December 31, 2011, the Credit Facility had no net change in unrealized (appreciation) depreciation. We use an independent third-party valuation firm to measure the fair value of the Credit Facility.

Revenue Recognition

Our revenue recognition policies are as follows:

Sales: Gains or losses on the sale of investments are calculated by using the specific identification method.

Interest Income: Interest income, adjusted for amortization of premium and accretion of discount, is recorded on an accrual basis. Origination, closing and/or commitment fees associated with investments in portfolio companies are accreted into interest income over the respective terms of the applicable loans. Upon the prepayment of a loan or debt security, any prepayment penalties and unamortized loan origination, closing and commitment fees are recorded as part of interest income. We may have loans in our portfolio that contain a PIK provision. PIK interest is accrued at the contractual rates and added to the loan principal on the reset dates.

42

Table of Contents

Non-accrual: Loans are placed on non-accrual status when principal or interest payments are past due 30 days or more or when there is reasonable doubt that principal or interest will be collected. Accrued interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment about ultimate collectability of principal. Non-accrual loans are restored to accrual status when past due principal and interest is paid and, in management’s judgment, are likely to remain current.

Payment-in-Kind Interest

We may have investments in our portfolio which contain a PIK interest provision. Over time, PIK interest increases the principal balance of the investment, but is recorded as interest income. For us to maintain our status as a RIC, substantially all of this income must be paid out to stockholders in the form of dividends, even though we have not currently collected cash with respect to the PIK interest.

New Accounting Pronouncements and Accounting Standards Updates

In May 2011, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (“ASU 2011-04”). ASU 2011-04 was issued concurrently with International Financial Reporting Standards No. 13 (“IFRS 13”), Fair Value Measurements, to provide largely identical guidance about fair value measurement and disclosure requirements as is currently required under ASU 2010-06, Fair Value Measurements and Disclosures (Topic 820). The new standards do not extend the use of fair value but, rather, provide guidance about how fair value should be applied where it already is required or permitted under IFRS or GAAP. For GAAP, most of the changes are clarifications of existing guidance or wording changes to align with IFRS 13. ASU 2011-04 eliminates the concepts of in-use and in-exchange when measuring fair value of all financial instruments. For Level 3 fair value measurements, the ASU requires that our disclosure include quantitative information about significant unobservable inputs, a qualitative discussion about the sensitivity of the fair value measurement to changes in the unobservable inputs and the interrelationship between inputs, and a description of our valuation process. Public companies are required to apply ASU 2011-04 prospectively for interim and annual periods beginning after December 15, 2011. The adoption of ASU 2011-04 did not have a significant impact on the Company’s financial statements or its disclosures.

Portfolio Investments

The total value of our investments was approximately $215.0 million and $177.7 million at March 31, 2012 and December 31, 2011, respectively. During the three months ended March 31, 2012, we originated approximately $40.3 million of new investments in one existing and five new portfolio companies. We had sales of approximately $4.5 million from one portfolio company and had principal repayments of approximately $1.3 million from 15 portfolio companies. During the period from January 28, 2011 to December 31, 2011, we originated approximately $219.1 million of new investments in 23 portfolio companies. We received approximately $32.0 million in sales from seven portfolio companies and approximately $2.2 million of principal repayments from 11 portfolio companies.

At March 31, 2012, we had investments in debt securities of 26 portfolio companies, totaling approximately $215.0 million. At December 31, 2011, we had investments in debt securities of 21 portfolio companies, totaling approximately $177.7 million.

43

Table of Contents

The following table shows the fair value of our portfolio of investments by asset class as of March 31, 2012 and December 31, 2011:

As of March 31, 2012, the weighted average yield on income producing investments in our portfolio was approximately 8.2% compared to 8.5% at December 31, 2011. The decrease in yield during the first three months of 2012 was primarily due to an increase in the fair value of portfolio assets. As of March 31, 2012 and December 31, 2011, there were no investments on non-accrual status.

Results of Operations for the Three Months ended March 31, 2012 compared to the Period January 28, 2011 (commencement of operations) to March 31, 2011

Revenue

Investment income of approximately $3.9 million for the quarter ended March 31, 2012 was primarily attributable to interest earned from investments in the 26 portfolio companies. Interest income is increasing on a quarterly basis due to growth in the size of the portfolio.

Investment income of approximately $0.1 million for the period ended March 31, 2011 was primarily attributable to interest earned from investments in three portfolio companies and from interest earned on cash and cash equivalents.

Expenses

For the quarter ended March 31, 2012 investment advisory and management fees of approximately $0.5 million were calculated at an annual rate of 1.00% of gross assets. Interest and other credit facility expenses of approximately $0.2 million were based upon balances drawn from the Credit Facility. Investment advisory and management fees, interest, and other credit facility expenses are increasing due to growth in the size of the portfolio. Remaining expenses of approximately $0.5 million are mostly for recurring general and administrative expenses.

For the period ended March 31, 2011, the majority of expenses were based upon estimated accruals for recurring general and administrative expenses. For the period ended March 31, 2011, investment advisory and management fees were waived and the Credit Facility was not established.

Net Realized and Unrealized Gain on Investments

For the quarter ended March 31, 2012, net realized and unrealized gains of approximately $3.1 million were attributable to the tightening of credit spreads in the secondary market and the strong financial health of our portfolio companies.

For the period ended March 31, 2011, net unrealized gains were mostly attributable to our investment in STHI Holding Corp.

Results of Operations for the Period January 28, 2011 to December 31, 2011

Solar Senior Capital was formed in December 2010 and commenced operations on January 28, 2011. As a result, there is no comparable period to compare results of operations for the period January 28, 2011 to December 31, 2011.

Revenue

Investment income of approximately $7.89 million for the period ended December 31, 2011 was primarily attributable to interest earned from investments in the 21 portfolio companies and from interest earned on cash and cash equivalents.

Expenses

The largest expense component was for debt issuance costs of approximately $2.80 million which were incurred for upfront commitment and legal fees related to the establishment of the Credit Facility on August 26, 2011. Investment advisory and management fees of approximately $0.94 million were calculated at an annual rate of 1.00% of gross assets. Remaining expenses of approximately $1.55 million were mostly for recurring general and administrative expenses.

Net Realized and Unrealized Loss on Investments

Net realized and unrealized losses of approximately $2.85 million were attributable to general weakness in fixed income prices and widening of credit market spreads, which occurred mostly during the third quarter of 2011.

Liquidity and Capital Resources

Our liquidity and capital resources were generated and are generally available through the Credit Facility, the proceeds of the IPO and Concurrent Private Placement, cash flows from operations, investment sales of liquid assets, repayments of loans, income earned on investments and cash equivalents, and we expect through periodic follow-on equity and/or debt offerings. We may from time to time issue securities in either public or private offerings. The issuance of debt or equity securities will depend on future market conditions, funding needs and other factors and there can be no assurance that any such issuance will occur or be successful.

The primary use of existing funds and any funds raised in the future is expected to be for investments in portfolio companies, cash distributions to our shareholders or for other general corporate purposes.

At March 31, 2012 and December 31, 2011, we had cash and cash equivalents of approximately $1.8 million and $2.9 million, respectively. Cash used in operating activities for the quarter ended March 31, 2012 and the period ended December 31, 2011 was approximately $8.7 million and $175.6 million, respectively. We expect that all current liquidity needs will be met with cash flows from operations, borrowings, and other activities. As of March 31, 2012, we had approximately $181.8 million of unused borrowing capacity under the Credit Facility.

Credit Facility

On August 26, 2011, we established a $200 million senior secured revolving credit facility with Citigroup Global Markets Inc. acting as administrative agent. The Credit Facility matures on August 26, 2016 and generally bears interest at a rate of LIBOR plus 2.25%. Under the Credit Facility, $150 million will be available initially with an additional $50 million available as a delayed draw. The Credit Facility can also be expanded up to $600 million. The Credit Facility is secured by all of the assets held by the SPV. Under the Credit Facility, Solar Senior and the SPV, as applicable, have made certain customary representations and warranties, and are required to comply with various covenants, including leverage restrictions, reporting requirements and other customary requirements for similar credit facilities. The Credit Facility includes usual and customary events of default for credit facilities of this nature.

Contractual Obligations

A summary of our significant contractual payment obligations are as follows:

We have certain commitments pursuant to our Investment Advisory and Management Agreement entered into with Solar Capital Partners. We have agreed to pay a fee for investment advisory and management services consisting of two components—a base management fee and an incentive fee. Payments under the Investment Advisory and Management Agreement are equal to (1) a percentage of the value of our average gross assets and (2) a two-part incentive fee. See “Investment Advisory and Management Agreement.” We have also entered into a contract with Solar Capital Management to serve as our administrator. Payments under the Administration Agreement are equal to an amount based upon our allocable portion of Solar Capital Management’s overhead in performing its obligation under the agreement, including rent, fees, and other expenses inclusive of our allocable portion of the compensation of our chief financial officer and any administrative staff. See “Administration Agreement.”

Off-Balance Sheet Arrangements

In the normal course of our business, we trade various financial instruments and may enter into various investment activities with off-balance sheet risk, which include forward foreign currency contracts. Generally, these financial instruments represent future commitments to purchase or sell other financial instruments at specific terms at future dates. These financial instruments contain varying degrees of off-balance sheet risk whereby changes in the market value or our satisfaction of the obligations may exceed the amount recognized in our Consolidated Statement of Assets and Liabilities.

Borrowings

We had borrowings of approximately $18.2 million and $8.6 million outstanding as of March 31, 2012 and December 31, 2011, respectively, under the Credit Facility.

Distributions and Dividends

The following table reflects the cash distributions, including dividends and returns of capital, if any, per share that we have declared on our common stock since our initial public offering:

Table of Contents

Tax characteristics of all dividends will be reported to shareholders on Form 1099 after the end of the calendar year. Our monthly dividends, if any, will be determined by our board of directors.

We intend to elect to be taxed as a RIC under Subchapter M of the Code. To maintain our RIC status, we must distribute at least 90% of our ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any, out of the assets legally available for distribution. In addition, although we currently intend to distribute net realized capital gains (net long-term capital gains in excess of short-term capital losses), if any, at least annually, out of the assets legally available for such distributions, we may in the future decide to retain such capital gains for investment.

We maintain an “opt out” dividend reinvestment plan for our common stockholders. As a result, if we declare a dividend, then stockholders’ cash dividends will be automatically reinvested in additional shares of our common stock, unless they specifically “opt out” of the dividend reinvestment plan so as to receive cash dividends.

Related Parties

We have entered into a number of business relationships with affiliated or related parties, including the following:

In addition, Solar Capital Partners presently serves as investment adviser to Solar Capital Ltd., a publicly-traded BDC with investable capital in excess of $1.3 billion that invests primarily in the mezzanine debt and equity securities of middle-market leveraged companies similar to those we intend to target for investment. In addition, Michael S. Gross, our chairman and chief executive officer, Bruce Spohler, our chief operating officer, and Nicholas Radesca, our chief financial officer, serve in similar capacities for Solar Capital Ltd. Solar Capital Partners and its affiliates may also manage other funds in the future that may have investment mandates that are

similar, in whole and in part, with ours. Solar Capital Partners and its affiliates may determine that an investment is appropriate for us and for Solar Capital Ltd. or one or more of those other funds. In such event, depending on the availability of such investment and other appropriate factors, Solar Capital Partners or its affiliates may determine that we should invest side-by-side with one or more other funds. Any such investments will be made only to the extent permitted by applicable law and interpretive positions of the SEC and its staff, and consistent with Solar Capital Partners’ allocation procedures.
