NOTE 1. ORGANIZATION

Blackstone Senior Floating Rate 2027 Term Fund (“BSL”, the “Fund”), is a diversified, closed-end management investment company. BSL was organized as a Delaware statutory trust on March 4, 2010. BSL was registered under the Investment Company Act of 1940, as amended (the “1940 Act”), on March 5, 2010. BSL commenced operations on May 26, 2010. Prior to that date, BSL had no operations other than matters relating to its organization and the sale and issuance of 5,236 common shares of beneficial interest in BSL to Blackstone Liquid Credit Strategies LLC (the “Adviser”) at a price of $19.10 per share. The Adviser serves as BSL’s investment adviser. BSL’s common shares are listed on the New York Stock Exchange (the “Exchange”) and trade under the ticker symbol “BSL.”

BSL will dissolve on or about May 31, 2027, absent shareholder approval to extend such term. Upon dissolution, BSL will distribute substantially all of its net assets to shareholders, after making appropriate provision for any liabilities. Pursuant to BSL’s Amended and Restated Agreement and Declaration of Trust, prior to the date of dissolution, a majority of BSL’s Board of Trustees (the “Board”), with the approval of a majority of the shareholders entitled to vote (as defined in the 1940 Act), may extend the life of BSL by a period of two years or such shorter time as may be determined. On March 31, 2017, BSL announced an extension of BSL’s reinvestment period. The extension allows BSL to continue to reinvest proceeds generated by maturities, prepayments and sales of investments until one year prior to BSL’s scheduled dissolution date. After the end of BSL's reinvestment period, BSL will stop reinvesting principal proceeds generated by maturities, prepayments and sales of investments. Principal proceeds after the reinvestment period may be distributed on a pro rata basis among the Fund’s common shareholders, noteholders and lenders, subject to any terms of any borrowing and/or notes issuances. Principal proceeds distributed to shareholders may constitute tax-advantaged returns of capital for U.S. federal income tax purposes. The Adviser will continue to receive a fee based on BSL's Managed Assets (defined in Note 3) for investment advisory services following the end of BSL's reinvestment period.

The Fund was previously classified as a non-diversified investment company for purposes of the 1940 Act. As a result of ongoing operations, the Fund as of April 1, 2014 is now classified as a diversified company. This means that with respect to 75% of the Fund’s total assets, no more than 5% of such Fund’s total assets may be invested in any one issuer, excepting cash and cash items, U.S. government securities, and securities of other investment companies. The Fund may not resume operating in a non-diversified manner without first obtaining shareholder approval in accordance with the 1940 Act.

Investment Objectives: BSL’s primary investment objective is to seek high current income, with a secondary objective to seek preservation of capital, consistent with its primary goal of high current income. Under normal market conditions, at least 80% of BSL’s Managed Assets (defined in Note 3) will be invested in senior secured, floating rate loans (“Senior Loans”).

Senior Loans, Secured Loans and Senior Secured Loans are referred to collectively as “Loans” throughout the Notes to Financial Statements.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation: The Fund’s financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and are stated in U.S. dollars. The Fund is considered an Investment Company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies in the Financial Accounting Standards Board Accounting Standards Codification Topic 946.

The preparation of financial statements requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statement. Actual results could differ from these estimates. The Fund operates as a single operating segment. As a result, the Fund’s segment accounting policies are consistent with those described herein and the Fund does not have any intra-segment sales and transfers of assets.

Portfolio Valuation: BSL's net asset value (“NAV”) is determined daily on each day that the Exchange is open for business, as of the close of the regular trading session on the Exchange. The Fund calculates NAV per share by subtracting liabilities (including accrued expenses or dividends) from the total assets of the Fund (the value of the securities plus cash or other assets, including interest accrued but not yet received) and dividing the result by the total number of outstanding common shares of the Fund.

Loans are primarily valued by using a composite loan price from a nationally recognized loan pricing service. The methodology used by the Fund's nationally recognized loan pricing provider for composite loan prices is to value loans at the mean of the bid and ask prices from one or more brokers or dealers. Collateralized Loan Obligation securities (“CLOs”) are valued at the price provided by a nationally recognized pricing service. The prices provided by the nationally recognized pricing service are typically based on the evaluated mid-price of each of the CLOs. Corporate bonds and convertible bonds, other than short-term investments, are valued at the price provided by a nationally recognized pricing service. The prices provided by the nationally recognized pricing service are typically based on the mean of bid and ask prices for each corporate bond security. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrices, market transactions in comparable investments, various relationships observed in the market between investments and calculated yield measures based on valuation technology commonly employed in the market for such investments. Equity securities for which market quotations are available are generally valued at the last sale price or official closing price on the primary market or exchange on which they trade. Futures contracts, if any, are ordinarily valued at the last sales price on the securities or commodities exchange on which they are traded. Written and purchased options, if any, are ordinarily valued at the closing price on the securities or commodities exchange on which they are traded. Open-end investment companies are generally valued at their closing net asset values as reported on each business day. To the extent current market quotations are not readily available, short-term debt investments, if any, having a remaining maturity of 60 days or less when purchased would be valued at cost adjusted for amortization of premiums and accretion of discounts.

March 31, 2026

In accordance with Rule 2a-5 under the 1940 Act, the Fund's Board of Trustees (the “Board”) has designated the Adviser as the valuation designee to perform fair value determinations related to the Fund’s investments, subject to the Board’s oversight and periodic reporting requirements.

Any investments and other assets for which such current market quotations are not readily available are valued at fair value (“Fair Valued Assets”) as determined in good faith by a committee of the Adviser (“Fair Valued Asset Committee”) under procedures established by, and under the general supervision and responsibility of, the Fund's Board. Such methods may include, but are not limited to, the use of a market comparable and/or income approach methodologies. A Fair Valued Asset Committee meeting may be called at any time by any member of the Fair Valued Asset Committee. The pricing of all Fair Valued Assets and determinations thereof shall be reported by the Adviser as the valuation designee to the Board at each regularly scheduled quarterly meeting. The Fund has procedures to identify and investigate potentially stale or missing prices for investments which are valued using a nationally recognized pricing service, exchange price or broker-dealer quotations. After performing such procedures, any prices which are deemed to be stale are reviewed by the Fair Valued Asset Committee and an alternative pricing source is determined.

Various inputs are used to determine the value of BSL's investments. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs are inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The three-tier hierarchy of inputs is summarized in the three broad levels listed below.

Level 1 — Unadjusted quoted prices in active markets for identical investments at the measurement date.

Level 2 — Significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.).

Level 3 — Significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments).

The categorization of a value determined for investments and other financial instruments is based on the pricing transparency of the investment and other financial instrument and does not necessarily correspond to the Fund's perceived risk of investing in those securities. Investments measured and reported at fair value are classified and disclosed in one of the following levels within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement.

March 31, 2026

The following tables summarize valuation of BSL's investments under the fair value hierarchy levels as of March 31, 2026:

Blackstone Senior Floating Rate 2027 Term Fund

The Fund may hold assets and/or liabilities in which the fair value approximates the carrying amount for financial statement purposes. As of March 31, 2026, the Fund's outstanding borrowings of $84,200,000 under its Leverage Facility are categorized as Level 2 within the fair value hierarchy.

March 31, 2026

The changes of the fair value of investments for which the Fund has used significant unobservable (Level 3) inputs to determine the fair value are as follows:

Information about Level 3 fair value measurements as of March 31, 2026:

A change to the unobservable input at the reporting date would result in a significant change to the value of the investment as follows:

Securities were transferred from Level 2 to Level 3 because of a lack of observable market data due to decrease in market activity and information for these securities. Other securities were transferred from Level 3 to Level 2 as observable inputs were available for purposes of valuing those assets.

Securities Transactions and Investment Income: Securities transactions are recorded on trade date for financial reporting purposes, and amounts payable or receivable for trades not settled at the time of period end are reflected as liabilities and assets, respectively. Interest income is recognized on an accrual basis from the date of settlement. Accretion of discount and amortization of premium, which are included in interest income, are accreted or amortized daily using the accrual basis interest method. Dividend income is recorded on the ex-dividend date. Realized gains and losses from securities transactions and foreign currency transactions, if any, are recorded on the basis of identified cost.

When the Fund sells a floating rate loan interest, it may pay an agency fee. The Fund earns facility and other fees on floating rate loan interests, and facility fees are typically amortized to income over the term of the loan. Consent and amendment fees are also recorded to income as earned.

NOTE 3. LOANS AND OTHER INVESTMENTS

BSL defines “Senior Loans” as senior secured, floating rate loans that are made to U.S. and, to a limited extent, non-U.S. corporations, partnerships and other business entities (“Borrowers”), which operate in various industries and geographical regions. Under normal market conditions, at least 80% of BSL’s Managed Assets (defined below) will be invested in Senior Loans. BSL defines “Managed Assets” as total assets (including any assets attributable to any leverage used) minus the sum of BSL's accrued liabilities (other than liabilities related to the principal amount of leverage). As of March 31, 2026, 90.41% of BSL’s Managed Assets were held in Senior Loans.

Senior Secured Loans hold a senior position in the capital structure of a business entity, are secured with specific collateral, and have a claim on the assets and/or stock of the Borrower that is senior to that held by unsecured creditors, subordinated debt holders and stockholders of the Borrower.

Loans often require prepayment from Borrowers’ excess cash flows or permit the Borrowers’ to repay at their election. The degree to which Borrowers repay, whether as a contractual requirement or at their election, cannot be predicted with accuracy. As a result, the actual remaining maturity may be substantially less than the stated maturities shown. However, floating rate loans typically have an expected average life of two to four years. Floating rate loans typically have rates of interest which are re-determined periodically, either daily, monthly, quarterly or semi-annually by reference to a floating base lending rate, primarily the Secured Overnight Financing Rate (“SOFR”), plus a premium or credit spread.

Loans are subject to the risk of payment defaults of scheduled interest or principal. Such non-payment could result in a reduction of income, a reduction in the value of the investment and a potential decrease in the NAV of the Fund. Risk of loss of income is generally higher for subordinated unsecured loans or debt, which are not backed by a security interest in any specific collateral. There can be no assurance that the liquidation of any collateral securing a Loan would satisfy the Borrower’s obligation to the Fund in the event of non-payment of scheduled interest or principal payments, or that such collateral could be readily liquidated.

Second lien loans generally are subject to similar risks as those associated with investments in first lien loans except that such loans are subordinated in payment and/or lower in lien priority to first lien holders. In the event of default on a second lien loan, the first priority lien holder has first claim to the underlying collateral of the loan. Second lien loans are subject to the additional risk that the cash flow of the Borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior obligations of the Borrower. As of March 31, 2026, BSL had invested $5,210,741 in second lien secured loans. Second lien secured loans are not considered Senior Loans for BSL.

Loans can be rated below investment grade or may also be unrated. As a result, the risks associated with Loans may be similar to the risks of other below investment grade securities, although they are senior and secured in contrast to other below investment grade securities, which are often subordinated or unsecured. The Fund typically invests in Loans rated below investment grade, which are considered speculative because of the credit risk of the Borrowers. Such companies are more likely than investment grade issuers to default on their payments of interest and principal owed to the Fund, and such defaults could reduce NAV and income distributions. The amount of public information available with respect to below investment grade loans will generally be less extensive than that available for registered or exchange-listed securities. In evaluating the creditworthiness of Borrowers, the Adviser will consider, and may rely in part on, analyses performed by others. The Adviser’s established best execution procedures and guidelines require trades to be placed for execution only with broker-dealer counterparties approved by the Counterparty Committee of the Adviser. The factors considered by the Counterparty Committee when selecting and approving brokers and dealers include, but are not limited to: (i) quality, accuracy, and timeliness of execution, (ii) review of the reputation, financial strength and stability of the financial institution, (iii) willingness and ability of the counterparty to commit capital, (iv) ongoing reliability and (v) access to underwritten offerings and secondary markets. The Counterparty Committee regularly reviews each broker-dealer counterparty based on the foregoing factors.

BSL may acquire Loans through assignments or participations. BSL typically acquires these Loans through assignment, and if BSL acquires a Loan through participation, it will seek to elevate a participation interest into an assignment as soon as practicably possible. The purchaser of an assignment typically succeeds to all the rights and obligations of the assigning institution and becomes a lender under the credit agreement with respect to the debt obligation. A participation typically results in a contractual relationship only with the institution participating out the interest, not with the Borrower. Sellers of participations typically include banks, broker-dealers, other financial institutions and lending institutions. The Adviser has adopted best execution procedures and guidelines which seek to mitigate credit and counterparty risk in the atypical situation when BSL must acquire a Loan through a participation.

BSL has invested in CLO securities. A CLO is a financing entity (generally called a Special Purpose Vehicle (“SPV”)), created to reapportion the risk and return characteristics of a pool of assets. While the assets underlying a CLO are typically Secured Loans, the assets may also include (i) unsecured loans, (ii) debt securities that are rated below investment grade, and (iii) equity securities incidental to investments in Secured Loans. When investing in CLOs, the Fund will not invest in equity tranches, which are the lowest tranche. However, the Fund may invest in lower tranches of CLO debt securities, which typically experience a lower recovery, greater risk of loss or deferral or non-payment of interest than more senior debt tranches of the CLO. In addition, the Fund intends to invest in CLOs consisting primarily of individual Secured Loans of Borrowers and not repackaged CLO obligations from other high risk pools. The underlying Secured Loans purchased by CLOs are generally performing at the time of purchase but may become non-performing, distressed or defaulted. CLOs with underlying assets of non-performing, distressed or defaulted loans are not contemplated to comprise a significant portion of the Fund’s investments in CLOs. The key feature of the CLO structure is the prioritization of the cash flows from a pool of debt securities among the several classes of the CLO. The SPV is a company founded solely for the purpose of securitizing payment claims arising out of this diversified asset pool. On this basis, marketable securities are issued by the SPV which, due to the diversification of the underlying risk, generally represent a lower level of risk than the original assets. The redemption of the securities issued by the SPV typically takes place on a date earlier than legal maturity from refinancing of the senior debt tranches.

NOTE 4. GENERAL COMMITMENTS AND CONTINGENCIES

As of March 31, 2026, BSL had unfunded loan commitments outstanding, which could be extended at the option of the borrower, as detailed below:

Unfunded loan commitments are marked to market on the relevant day of the valuation in accordance with BSL’s valuation policies. For the period ended March 31, 2026, BSL recorded a net increase in unrealized depreciation on unfunded loan commitments totaling $9,189.

NOTE 5. LEVERAGE

The Fund terminated its previously existing leverage facility and entered into a new, separate Credit Agreement (the “Agreement”), dated December 24, 2024, with a new lender to borrow up to a limit of $100 million pursuant to an evergreen revolving line of credit (the “Leverage Facility”). The Leverage Facility does not have a scheduled maturity date, but can be terminated (i) by the Fund upon at least three (3) business days’ written notice to the lender under the Leverage Facility or (ii) by such lender on the latest to occur of (a) the 365th day after the initial closing date of the Leverage Facility, (b) the 270th day after such lender delivers a notice of termination to the Fund or (c) a later date specified by such lender in the notice of termination. Borrowings under the Agreement are secured by the assets of the Fund.

Interest on outstanding revolving loans under the Leverage Facility is currently charged at a rate of 1.15% above adjusted term SOFR, with either a one (1) month interest period or three (3) month interest period as elected by the Fund. The Fund may also elect to borrow daily interest rate loans based on a customary alternate base rate.

Under the terms of the Agreement, the Fund must pay a commitment fee on any undrawn amounts, currently in an amount equal to 0.15% on the undrawn amounts when drawn amounts equal or exceed 75% of the borrowing limit and 0.25% on the undrawn amounts at any other time. Interest is generally payable at the end of the respective interest period and fees are generally payable after the end of each calendar quarter. As of March 31, 2026, BSL had borrowings outstanding under its Leverage Facility of $84,200,000, at an interest rate of 4.82%. Due to the short term nature of the Agreement, face value approximates fair value at March 31, 2026. This fair value is based on Level 2 inputs under the three-tier fair valuation hierarchy (see Note 2). For the period ended March 31, 2026, the average borrowings under BSL’s Leverage Facility and the weighted average interest rate were $85,733,333 and 4.76%, respectively. During the period ended March 31, 2026, the Fund incurred $5,393 for commitment fees on undrawn amounts.

Under the Agreement, the Fund has agreed to certain covenants and additional investment limitations while the leverage is outstanding. The Fund has agreed to maintain asset coverage of three times over borrowings. Compliance with the investment restrictions and calculations are performed by the Fund’s custodian, The Bank of New York Mellon. As of March 31, 2026, the Fund was in compliance with all required investment limitations and asset coverage requirements related to its leverage.

March 31, 2026

The use of borrowings to leverage the common shares of the Fund can create risks. Changes in the value of the Fund’s portfolio, including securities bought with the proceeds of leverage, are borne entirely by the holders of common shares of the Fund. All costs and expenses related to any form of leverage used by the Fund are borne entirely by common shareholders. If there is a net decrease or increase in the value of the Fund’s investment portfolio, the leverage may decrease or increase, as the case may be, the NAV per common share to a greater extent than if the Fund did not utilize leverage. During periods when the Fund is using leverage, the fees paid to the Adviser for advisory services and to ALPS for administrative services are higher than if the Fund did not use leverage because the fees paid are calculated on the basis of the Fund’s Managed Assets, which include the assets purchased through leverage. As of March 31, 2026, BSL’s leverage represented 32.51% of the Fund’s Managed Assets.
