Performance and Risk Disclosure

There is no assurance that the Fund will achieve its investment objectives. The Fund is subject to market risk, which is the possibility that the market values of securities owned by the Fund will decline and that the value of the Fund’s shares may therefore be less than what you paid for them. Accordingly, you can lose money by investing in the Fund. See “Principal Risks” in the Investment Objectives, Policies, Risks and Effects of Leverage section of this report for a discussion of certain other risks of investing in the Fund.

Performance data quoted represents past performance, which is no guarantee of future results, and current performance may be lower or higher than the figures shown. For the most recent month-end performance figures, please visit www.ftportfolios.com or speak with your financial advisor. Investment returns, net asset value and common share price will fluctuate and Fund shares, when sold, may be worth more or less than their original cost.

The Advisor may also periodically provide additional information on Fund performance on the Fund’s web page at www.ftportfolios.com.

The ratings are by S&P Global Ratings except where otherwise indicated. A credit rating is an assessment provided by a nationally recognized statistical rating organization (NRSRO) of the creditworthiness of an issuer with respect to debt obligations except for those debt obligations that are only privately rated. Ratings are measured on a scale that generally ranges from AAA (highest) to D (lowest). Investment grade is defined as those issuers that have a long-term credit rating of BBB- or higher. The credit ratings shown relate to the creditworthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. Credit ratings are subject to change.

Portfolio Commentary

First Trust Senior Floating Rate Income Fund II (FCT)

Annual Report

May 31, 2025 (Unaudited)

Advisor

The First Trust Advisors L.P. (“First Trust”) Leveraged Finance Team is comprised of 20 experienced investment professionals specializing in below investment grade securities. The team is comprised of portfolio management, research, trading and operations personnel. As of May 31, 2025, the First Trust Leveraged Finance Team managed or supervised approximately $6.9 billion in senior secured bank loans and high-yield bonds. These assets are managed across various strategies, including two closed-end funds, an open-end fund, and five exchange-traded funds on behalf of retail and institutional clients.

Portfolio Management Team

William Housey, CFA - Managing Director of Fixed Income, Senior Portfolio Manager

Jeffrey Scott, CFA - Senior Vice President, Portfolio Manager

Kevin Ziets, CFA - Senior Vice President, Portfolio Manager

First Trust Senior Floating Rate Income Fund II

The primary investment objective of the First Trust Senior Floating Rate Income Fund II (the “Fund”) is to seek a high level of current income. As a secondary objective, the Fund attempts to preserve capital. The Fund pursues its investment objectives by investing primarily in a portfolio of senior secured floating-rate corporate loans (“Senior Loans”). Under normal market conditions, the Fund invests at least 80% of its Managed Assets in a diversified portfolio of Senior Loans. It is anticipated that at least 80% of the Fund’s Managed Assets are invested in lower grade debt instruments, although from time to time all of the Fund’s Managed Assets may be invested in such lower grade debt instruments. “Managed Assets” means the total asset value of the Fund minus the sum of its liabilities, other than the principal amount of borrowings. There can be no assurance that the Fund will achieve its investment objectives. Investing in Senior Loans involves credit risk and, during periods of generally declining credit quality, it may be particularly difficult for the Fund to achieve its secondary investment objective. The Fund may not be appropriate for all investors.

Commentary

During the 12-month period ended May 31, 2025, the Fund returned(1) 7.38% based on net asset value (“NAV”) and 5.96% based on market price. This compares to the Morningstar® LSTA® US Leveraged Loan Index’s (the “Benchmark”) return of 6.78% over the same period.

The following key factors impacted Fund performance relative to the Benchmark during the period:

•

Industry: Relative to the Benchmark, the primary contributors to the Fund’s performance were its selection within the media & entertainment industry, its underweight allocation to and selection within the capital goods industry, and its selection within the food, beverage & tobacco industry. Partially mitigating those tailwinds were the Fund’s underweight allocation to and selection within the telecommunication services, technology hardware & equipment, and utilities industries.

•

Asset Type: The Fund’s bond allocation, while relatively small, was a significant positive contributor to performance relative to the Benchmark as bonds outperformed loans during the period (the ICE BofA US High Yield Constrained Index returned 9.27% for the period). The Fund’s loan selection also significantly benefited performance relative to the Benchmark. The Fund began the period with allocations of 4.33% to bonds and 95.67% to loans and ended the period with allocations of 1.35% to bonds and 98.65% to loans.

•

Credit Quality: The Fund maintained a defensive high-quality bias. Performance across the credit quality spectrum was positive during the Period but assets rated B, and BB generally outperformed those rated CCC and below. The Fund benefited from its selection across the credit quality spectrum and its underweight allocation to assets rated CCC and below.

•

Leverage: The Fund’s use of leverage was the largest positive contributor to performance relative to the Benchmark. The Fund began the period with 9.76% leverage and ended the period with 16.42%.

•

Loan Spreads, Yields and Prices: Loan spreads over the Secured Overnight Financing Rate (“SOFR” or “base rate”) remained relatively flat throughout the period and ended at S+446 basis points (“bps”). While loan spreads ended the period modestly below the long-term average of S+506 bps (January 1997 – May 2025), yields of 8.55% remain well above the long-term average of 7.12% (January 1997 – May 2025) driven by elevated base rates. Loan prices also remained relatively unchanged throughout the period and ended at $96.70 and remain at a discount to par ($100).

•

Defaults: The Fund experienced zero defaults during the period, compared to 14 defaults in the Benchmark. Since the Leveraged Finance Team began managing the Fund, the Fund experienced 13 defaults, compared to 220 defaults in the Benchmark over the same time frame. The loan market default rate fell from 1.08% at the beginning of the period to 0.74% at the end of the period, remaining well below the long-term average of 2.58% (October 1998 – May 2025). The avoidance of defaults generally benefits performance.

Performance Analysis

		Average Annual Total Returns
	1 Year Ended 5/31/25	5 Years Ended 5/31/25	10 Years Ended 5/31/25	Inception (5/25/04) to 5/31/25
Fund Performance(1)
NAV	7.38 %	7.06 %	5.16 %	4.68 %
Market Value	5.96 %	8.10 %	5.16 %	4.13 %
Index Performance
Morningstar® LSTA® US Leveraged Loan Index	6.78 %	7.52 %	5.01 %	5.02 %

Performance figures assume reinvestment of all distributions and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. The Fund’s past performance does not predict future performance.

The Fund has a practice of seeking to maintain relatively stable monthly distribution, which may be changed at any time. The practice has no impact on the Fund’s investment strategy and may reduce the Fund’s NAV. However, the Advisor believes the practice helps maintain the Fund’s competitiveness and may benefit the Fund’s market price and premium/discount to the Fund’s NAV. The monthly distribution rate was $0.0970 throughout the period. At the $0.0970 per share monthly distribution rate, the annualized distribution rate at May 31, 2025 was 11.00% based on NAV and 11.75% based on market price. For the twelve-month period ended May 31, 2025, 68.64% of the distributions were characterized as ordinary income and 31.36% of the distributions were characterized as return of capital. The final determination of the source and tax status of all 2025 distributions will be made after the end of 2025 and will be provided on Form 1099-DIV. The foregoing is not to be construed as tax advice. Please consult your tax advisor for further information regarding tax matters.

(a)	Senior Floating- Rate Loan Interests (“Senior Loans”) in which the Fund invests pay interest at rates which are periodically predetermined by reference to a base lending rate plus a premium. These base lending rates are generally (i) the SOFR obtained from the U.S. Department of the Treasury’s Office of Financial Research or another major financial institution, (ii) the lending rate offered by one or more major European banks, (iii) the prime rate offered by one or more United States banks or (iv) the certificate of deposit rate. Certain Senior Loans are subject to a SOFR floor that establishes a minimum SOFR rate. When a range of rates is disclosed, the Fund holds more than one contract within the same tranche with identical SOFR period, spread and floor, but different SOFR reset dates.
(b)	Senior Loans generally are subject to mandatory and/or optional prepayment. As a result, the actual remaining maturity of Senior Loans may be substantially less than the stated maturities shown.
(c)	All or a portion of these securities serve as collateral for the outstanding loan unless otherwise indicated. At May 31, 2025, the segregated value of these securities amounts to $345,482,514.
(d)	This security does not serve as collateral for the outstanding loan.
(e)	This security, sold within the terms of a private placement memorandum, is exempt from registration upon resale under Rule 144A of the Securities Act of 1933, as amended (the “1933 Act”), and may be resold in transactions exempt from registration, normally to qualified institutional buyers. Pursuant to procedures adopted by the Fund’s Board of Trustees, this security has been determined to be liquid by First Trust Advisors L.P. (the “Advisor”). Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security specific factors and assumptions, which require subjective judgment. At May 31, 2025, securities noted as such amounted to $4,682,540 or 1.7% of net assets.
(f)	This issuer has filed for protection in bankruptcy court.
(g)	Security received in a transaction exempt from registration under the 1933 Act. The security may be resold pursuant to an exemption from registration under the 1933 Act, typically to qualified institutional buyers (see Note 2D - Restricted Securities in the Notes to Financial Statements).
(h)	Non-income producing security.
(i)	This security is fair valued by the Advisor’s Pricing Committee in accordance with procedures approved by the Fund’s Board of Trustees, and in accordance with the provisions of the Investment Company Act of 1940 and rules thereunder, as amended. At May 31, 2025, securities noted as such are valued at $0 or 0.0% of net assets.
(j)	Pursuant to procedures adopted by the Fund’s Board of Trustees, this security has been determined to be illiquid by the Advisor.
(k)	This security’s value was determined using significant unobservable inputs (see Note 2A – Portfolio Valuation in the Notes to Financial Statements).
(l)	Rate shown reflects yield as of May 31, 2025.

Notes to Financial Statements

First Trust Senior Floating Rate Income Fund II (FCT)

May 31, 2025

1. Organization

First Trust Senior Floating Rate Income Fund II (the “Fund”) is a diversified, closed-end management investment company organized as a Massachusetts business trust on March 25, 2004, and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund trades under the ticker symbol “FCT” on the New York Stock Exchange (“NYSE”).

The primary investment objective of the Fund is to seek a high level of current income. As a secondary objective, the Fund attempts to preserve capital. The Fund pursues its investment objectives by investing primarily in a portfolio of senior secured floating-rate corporate loans (“Senior Loans”)(1). Under normal market conditions, the Fund invests at least 80% of its Managed Assets in a diversified portfolio of Senior Loans. “Managed Assets” means the total asset value of the Fund minus the sum of its liabilities, other than the principal amount of borrowings. There can be no assurance that the Fund will achieve its investment objectives. Investing in Senior Loans involves credit risk and, during periods of generally declining credit quality, it may be particularly difficult for the Fund to achieve its secondary investment objective. The Fund may not be appropriate for all investors.

2. Significant Accounting Policies

The Fund is considered an investment company and follows accounting and reporting guidance under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, “Financial Services-Investment Companies.” The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of the financial statements. The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.

A. Portfolio Valuation

The net asset value (“NAV”) of the Common Shares of the Fund is determined daily as of the close of regular trading on the NYSE, normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Domestic debt securities and foreign securities are priced using data reflecting the earlier closing of the principal markets for those securities. The Fund’s NAV per Common Share is calculated by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses, dividends declared but unpaid and any borrowings of the Fund), by the total number of Common Shares outstanding.

The Fund’s investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent readily available market quotations such as last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Fund’s investment advisor, First Trust Advisors L.P. (“First Trust” or the “Advisor”), in accordance with valuation procedures approved by the Fund’s Board of Trustees, and in accordance with provisions of the 1940 Act and rules thereunder. Investments valued by the Advisor’s Pricing Committee, if any, are footnoted as such in the footnotes to the Portfolio of Investments. The Fund’s investments are valued as follows:

Senior Loans are not listed on any securities exchange or board of trade. Senior Loans are typically bought and sold by institutional investors in individually negotiated private transactions that function in many respects like an over-the-counter secondary market, although typically no formal market-makers exist. This market, while having grown substantially since its inception, generally has fewer trades and less liquidity than the secondary market for other types of securities. Some Senior Loans have few or no trades, or trade infrequently, and information regarding a specific Senior Loan may not be widely available or may be incomplete. Accordingly, determinations of the market value of Senior Loans may be based on infrequent and dated information. Because there is less reliable, objective data available, elements of judgment may play a greater role in valuation of Senior Loans than for other types of securities. Typically, Senior Loans are fair valued using information provided by a third-party pricing service. The third-party pricing service primarily uses over-the-counter pricing from dealer runs and broker quotes from indicative sheets to value the Senior Loans. If the third-party pricing service cannot or does not provide a valuation for a particular Senior Loan or such valuation is deemed unreliable, the Advisor’s Pricing Committee may value such Senior Loan at a fair value according to procedures approved by the Fund’s Board of Trustees, and in accordance with the provisions of the 1940 Act and rules thereunder. Fair valuation of a Senior Loan is based on the consideration of all available information, including, but not limited to the following:

the most recent price provided by a pricing service;

(1)

The terms “security” and “securities” used throughout the Notes to Financial Statements include Senior Loans.

available market prices for the fixed-income security;

the fundamental business data relating to the borrower;

an evaluation of the forces which influence the market in which these securities are purchased and sold;

the type, size and cost of the security;

the financial statements of the borrower, or the financial condition of the country of issue;

the credit quality and cash flow of the borrower, or country of issue, based on the Pricing Committee’s, sub-advisor’s or portfolio manager’s analysis, as applicable, or external analysis;

the information as to any transactions in or offers for the security;

the price and extent of public trading in similar securities (or equity securities) of the borrower, or comparable companies;

10)

the coupon payments;

11)

the quality, value and salability of collateral, if any, securing the security;

12)

the business prospects of the borrower, including any ability to obtain money or resources from a parent or affiliate and an assessment of the borrower’s management;

13)

the prospects for the borrower’s industry, and multiples (of earnings and/or cash flows) being paid for similar businesses in that industry;

14)

the borrower’s competitive position within the industry;

15)

the borrower’s ability to access additional liquidity through public and/or private markets; and

16)

other relevant factors.

Common stocks and other equity securities listed on any national or foreign exchange (excluding Nasdaq, Inc. (“Nasdaq”) and the London Stock Exchange Alternative Investment Market (“AIM”)) are valued at the last sale price on the exchange on which they are principally traded or, for Nasdaq and AIM securities, the official closing price. Securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, at the close of the securities exchange representing the primary exchange for such securities.

Shares of open-end funds are valued based on NAV per share.

Equity securities traded in an over-the-counter market are valued at the close price or the last trade price.

Corporate bonds, corporate notes and other debt securities are fair valued on the basis of valuations provided by a third-party pricing service approved by the Advisor’s Pricing Committee, which may use the following valuation inputs when available:

benchmark yields;

reported trades;

broker/dealer quotes;

issuer spreads;

benchmark securities;

bids and offers; and

reference data including market research publications.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Advisor’s Pricing Committee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended (the “1933 Act”)) for which a third-party pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of the Fund’s NAV or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the third-party pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchanges. A variety of factors may be considered in determining the fair value of such securities, including, but not limited to, the following:

the last sale price on the exchange on which they are principally traded or, for Nasdaq and AIM securities, the official closing price;

the type of security;

the size of the holding;

Page 24

Notes to Financial Statements (Continued)

First Trust Senior Floating Rate Income Fund II (FCT)

May 31, 2025

the initial cost of the security;

transactions in comparable securities;

price quotes from dealers and/or third-party pricing services;

relationships among various securities;

information obtained by contacting the issuer, analysts, or the appropriate stock exchange;

an analysis of the issuer’s financial statements;

10)

the existence of merger proposals or tender offers that might affect the value of the security; and

11)

other relevant factors.

The Fund is subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows:

•

Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

•

Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:

Quoted prices for similar investments in active markets.

Quoted prices for identical or similar investments in markets that are non-active. A non-active market is a market where there are few transactions for the investment, the prices are not current, or price quotations vary substantially either over time or among market makers, or in which little information is released publicly.

Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).

Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

•

Level 3 – Level 3 inputs are unobservable inputs. Unobservable inputs may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value the Fund’s investments as of May 31, 2025, is included with the Fund’s Portfolio of Investments.

B. Security Transactions and Investment Income

Security transactions are recorded as of the trade date. Realized gains and losses from securities transactions are recorded on the identified cost basis. Interest income is recorded on the accrual basis. Market premiums and discounts are amortized to the earliest call date of each respective borrowing.

Securities purchased or sold on a when-issued, delayed-delivery or forward purchase commitment basis may have extended settlement periods. The value of the security so purchased is subject to market fluctuations during this period. Due to the nature of the Senior Loan market, the actual settlement date may not be certain at the time of the purchase or sale for some of the Senior Loans. Interest income on such Senior Loans is not accrued until settlement date. The Fund maintains liquid assets with a current value at least equal to the amount of its when-issued, delayed-delivery or forward purchase commitments until payment is made. At May 31, 2025, the Fund had no when-issued, delayed-delivery or forward purchase commitments (other than the unfunded commitments discussed below).

C. Unfunded Loan Commitments

The Fund may enter into certain credit agreements, all or a portion of which may be unfunded. The Fund is obligated to fund these loan commitments at the borrower’s discretion. Unfunded loan commitments are marked-to-market daily, and any unrealized appreciation (depreciation) is included in the Statement of Assets and Liabilities and Statement of Operations. Unfunded loan commitments are categorized as Level 2 within the fair value hierarchy. In connection with these commitments, the Fund earns a commitment fee typically set as a percentage of the commitment amount. The commitment fees are included in “Other” under Investment Income on the Statement of Operations. As of May 31, 2025, the Fund had the following unfunded loan commitments:

		$530,424	$530,980	$556

D. Restricted Securities

The Fund holds restricted securities, which are securities that may not be offered for public sale without first being registered under the 1933 Act. Prior to registration, restricted securities may only be resold in transactions exempt from registration under Rule 144A under the 1933 Act, normally to qualified institutional buyers. As of May 31, 2025, the Fund held restricted securities as shown in the following table that the Advisor has deemed illiquid pursuant to procedures adopted by the Fund’s Board of Trustees. Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security-specific factors and assumptions, which require subjective judgment. The Fund does not have the right to demand that such securities be registered. These securities are valued according to the valuation procedures as stated in the Portfolio Valuation note (Note 2A) and are not expressed as a discount to the carrying value of a comparable unrestricted security.

Security	Acquisition Date	Shares	Current Price	Carrying Cost	Value	% of Net Assets
Akorn, Inc.	10/15/2020	150,392	$0.04	$1,724,086	$6,016	0.00 %*
* Amount is less than 0.01%.

E. Dividends and Distributions to Shareholders

The Fund will distribute to holders of its Common Shares monthly dividends of all or a portion of its net income after the payment of interest and dividends in connection with leverage, if any. Distributions of any net long-term capital gains earned by the Fund are distributed at least annually. Distributions will automatically be reinvested into additional Common Shares pursuant to the Fund’s Dividend Reinvestment Plan unless cash distributions are elected by the shareholder.

Distributions from net investment income and realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These permanent differences are primarily due to the varying treatment of income and gain/loss on portfolio securities held by the Fund and have no impact on net assets or NAV per share. Temporary differences, which arise from recognizing certain items of income, expense and gain/loss in different periods for financial statement and tax purposes, will reverse at some point in the future. Permanent differences incurred during the fiscal year ended May 31, 2025, resulting in book and tax accounting differences, have been reclassified at year end to reflect an increase in accumulated net investment income (loss) of $14,832, a decrease in accumulated net realized gain (loss) of $14,980, and an increase to paid-in capital of $148. Accumulated distributable earnings (loss) consists of accumulated net investment income (loss), accumulated net realized gain (loss) on investments, and unrealized appreciation (depreciation) on investments. Net assets were not affected by this reclassification.

The tax character of distributions paid by the Fund during the fiscal years ended May 31, 2025 and 2024, was as follows:

Distributions paid from:	2025	2024
Ordinary income	$20,759,404	$23,583,385
Capital gains	—	—
Return of capital	9,485,260	6,661,278

Page 26

Notes to Financial Statements (Continued)

First Trust Senior Floating Rate Income Fund II (FCT)

May 31, 2025

As of May 31, 2025, the components of distributable earnings and net assets on a tax basis were as follows:

Undistributed ordinary income	$—
Undistributed capital gains	—
Total undistributed earnings	—
Accumulated capital and other losses	(58,880,115 )
Net unrealized appreciation (depreciation)	(3,177,968 )
Total accumulated earnings (losses)	(62,058,083 )
Other	—
Paid-in capital	336,930,250
Total net assets	$274,872,167

F. Income Taxes

The Fund intends to continue to qualify as a regulated investment company by complying with the requirements under Subchapter M of the Internal Revenue Code of 1986, as amended, which includes distributing substantially all of its net investment income and net realized gains to shareholders. Accordingly, no provision has been made for federal and state income taxes. However, due to the timing and amount of distributions, the Fund may be subject to an excise tax of 4% of the amount by which approximately 98% of the Fund’s taxable income exceeds the distributions from such taxable income for the calendar year.

The Fund is subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. The taxable years ended 2022, 2023, 2024, and 2025 remain open to federal and state audit. As of May 31, 2025, management has evaluated the application of these standards to the Fund and has determined that no provision for income tax is required in the Fund’s financial statements for uncertain tax positions.

The Fund intends to utilize provisions of the federal income tax laws, which allow it to carry a realized capital loss forward indefinitely following the year of the loss and offset such loss against any future realized capital gains. The Fund is subject to certain limitations under U.S. tax rules on the use of capital loss carryforwards and net unrealized built-in losses. These limitations apply when there has been a 50% change in ownership. At May 31, 2025, for federal income tax purposes, the Fund had $58,880,115 of non-expiring capital loss carryforwards available, to the extent provided by regulations, to offset future capital gains. To the extent that these loss carryforwards are used to offset future capital gains, it is probable that the capital gains so offset will not be distributed to the Fund’s shareholders.

Certain losses realized during the current fiscal year may be deferred and treated as occurring on the first day of the following fiscal year for federal income tax purposes. For the fiscal year ended May 31, 2025, the Fund did not incur any late year capital losses.

As of May 31, 2025, the aggregate cost, gross unrealized appreciation, gross unrealized depreciation, and net unrealized appreciation/(depreciation) on investments (including short positions and derivatives, if any) for federal income tax purposes were as follows:

Tax Cost	Gross Unrealized Appreciation	Gross Unrealized (Depreciation)	Net Unrealized Appreciation (Depreciation)
$349,490,422	$923,136	$(4,101,660)	$(3,178,524)

G. Expenses

The Fund will pay all expenses directly related to its operations.

H. Segment Reporting

The Fund has adopted FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. Adoption of the standard impacted financial statement disclosures only and did not affect the Fund’s financial position or the results of its operations. An operating segment is defined in Topic 280 as a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by the public entity’s chief operating decision maker (“CODM”) to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available. The CODM is the President and Chief Executive Officer of the Fund. The Fund operates as a single operating segment. The Fund’s income, expenses, assets, changes in net assets resulting from operations

and performance are regularly monitored and assessed as a whole by the CODM responsible for oversight functions of the Fund, using the information presented in the financial statements and financial highlights.

3. Investment Advisory Fee, Affiliated Transactions and Other Fee Arrangements

First Trust, the investment advisor to the Fund, is a limited partnership with one limited partner, Grace Partners of DuPage L.P., and one general partner, The Charger Corporation. The Charger Corporation is an Illinois corporation controlled by James A. Bowen, Chief Executive Officer of First Trust. First Trust is responsible for the selection and ongoing monitoring of the Fund’s investment portfolio, managing the Fund’s business affairs and providing certain administrative services necessary for the management of the Fund. For these investment management services, First Trust is entitled to a monthly fee calculated at an annual rate of 0.75% of the Fund’s Managed Assets. First Trust also provides fund reporting services to the Fund for a flat annual fee in the amount of $9,250.

5. Borrowings

The Fund has a committed facility agreement (the “Credit Agreement”) with The Toronto-Dominion Bank, New York Branch that has a maximum commitment amount of $120,000,000. Prior to December 10, 2024, the maximum commitment amount was $126,000,000. The borrowing rate under the Credit Agreement is equal to Term SOFR plus 1.05%. In addition, under the Credit Agreement, the Fund pays a commitment fee of 0.35% per annum on the undrawn amount, unless the average daily principal outstanding amount during the applicable interest period is less than $68,000,000, in which case the unused commitment fee rate will equal 0.40% per annum. Prior to December 10, 2024, the commitment fee was 0.35% on the undrawn amount of the facility when the utilization was below 90% of the maximum commitment amount. For the fiscal year ended May 31, 2025 the average amount outstanding was $36,369,863, with the average weighted average interest rate of 5.79%. As of May 31, 2025, the Fund had $54,000,000 loans outstanding which approximates fair value, under the Credit Agreement. The borrowings are categorized as Level 2 within the fair value hierarchy. The high and low annual interest rates during the fiscal year ended May 31, 2025 were 6.45% and 5.35%, respectively. The weighted average interest rate at May 31, 2025 was 5.38%. The interest and fees are included in “Interest and fees on loans” on the Statement of Operations.

6. Indemnification

The Fund has a variety of indemnification obligations under contracts with its service providers. The Fund’s maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Trustees of First Trust Senior Floating Rate Income Fund II:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of First Trust Senior Floating Rate Income Fund II (the “Fund”), including the portfolio of investments, as of May 31, 2025, the related statements of operations and cash flows for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of May 31, 2025, and the results of its operations and its cash flows for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of May 31, 2025, by correspondence with the custodian, agent banks and brokers; when replies were not received from agent banks and brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Dividend Reinvestment Plan

If your Common Shares are registered directly with the Fund or if you hold your Common Shares with a brokerage firm that participates in the Fund’s Dividend Reinvestment Plan (the “Plan”), unless you elect, by written notice to the Fund, to receive cash distributions, all dividends, including any capital gain distributions, on your Common Shares will be automatically reinvested by Computershare Trust Company N.A. (the “Plan Agent”), in additional Common Shares under the Plan. If you elect to receive cash distributions, you will receive all distributions in cash paid by check mailed directly to you by the Plan Agent, as the dividend paying agent.

If you decide to participate in the Plan, the number of Common Shares you will receive will be determined as follows:

(1)

If Common Shares are trading at or above net asset value (“NAV”) at the time of valuation, the Fund will issue new shares at a price equal to the greater of (i) NAV per Common Share on that date or (ii) 95% of the market price on that date.

(2)

If Common Shares are trading below NAV at the time of valuation, the Plan Agent will receive the dividend or distribution in cash and will purchase Common Shares in the open market, on the NYSE or elsewhere, for the participants’ accounts. It is possible that the market price for the Common Shares may increase before the Plan Agent has completed its purchases. Therefore, the average purchase price per share paid by the Plan Agent may exceed the market price at the time of valuation, resulting in the purchase of fewer shares than if the dividend or distribution had been paid in Common Shares issued by the Fund. The Plan Agent will use all dividends and distributions received in cash to purchase Common Shares in the open market within 30 days of the valuation date except where temporary curtailment or suspension of purchases is necessary to comply with federal securities laws. Interest will not be paid on any uninvested cash payments.

You may elect to opt-out of or withdraw from the Plan at any time by giving written notice to the Plan Agent, or by telephone at (866) 340-1104, in accordance with such reasonable requirements as the Plan Agent and the Fund may agree upon. If you withdraw or the Plan is terminated, you will receive a certificate for each whole share in your account under the Plan, and you will receive a cash payment for any fraction of a share in your account. If you wish, the Plan Agent will sell your shares and send you the proceeds, minus brokerage commissions.

The Plan Agent maintains all Common Shareholders’ accounts in the Plan and gives written confirmation of all transactions in the accounts, including information you may need for tax records. Common Shares in your account will be held by the Plan Agent in non-certificated form. The Plan Agent will forward to each participant any proxy solicitation material and will vote any shares so held only in accordance with proxies returned to the Fund. Any proxy you receive will include all Common Shares you have received under the Plan.

There is no brokerage charge for reinvestment of your dividends or distributions in Common Shares. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases.

Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due upon receiving dividends and distributions. Capital gains and income are realized although cash is not received by you. Consult your financial advisor for more information.

If you hold your Common Shares with a brokerage firm that does not participate in the Plan, you will not be able to participate in the Plan and any dividend reinvestment may be effected on different terms than those described above.

The Fund reserves the right to amend or terminate the Plan if in the judgment of the Board of Trustees the change is warranted. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. Additional information about the Plan may be obtained by writing Computershare, Inc., P.O. Box 43006, Providence, RI 02940-3006.

Mr. Ziets holds the FINRA Series 7 and Series 63 licenses and holds the Chartered Financial Analyst designation. He is a member of the CFA Institute and the CFA Society of New York.

During the Fund’s most recent fiscal year, there were no material changes to the Fund’s investment objectives or policies that have not been approved by shareholders or in the principal risk factors associated with an investment in the Fund.

Investment Objectives

The Fund’s primary objective is to seek a high level of current income. As a secondary objective, the Fund attempts to preserve capital.

Principal Investment Policies

The Fund pursues its investment objectives through investment in a portfolio of Senior Loans. There can be no assurance that the Fund will achieve its investment objectives. Investment in Senior Loans involves credit risk and, during periods of generally declining credit quality, it may be particularly difficult for the Fund to achieve its secondary investment objective.

Under normal market conditions, the Fund invests at least 80% of its Managed Assets in a diversified portfolio of Senior Loans. The portion of the Fund’s assets invested in Senior Loans will vary from time to time consistent with the Fund’s investment objectives, changes in market prices for Senior Loans, changes in interest rates and other economic and market factors. Senior Loans generally hold one of the most senior positions in the capital structure of a business entity (the “Borrower”), are typically secured with specific collateral and have a claim on the assets and/or stock of the Borrower that is senior to that held by subordinated debtholders and stockholders of the Borrower. The proceeds of Senior Loans primarily are used to finance leveraged buyouts, recapitalizations, mergers, acquisitions, stock repurchases, and, to a lesser extent, to finance internal growth and for other corporate purposes. Senior Loans have rates of interest which are typically redetermined either monthly, quarterly or semiannually by reference to a base lending rate, plus a premium. The Senior Loans in which the Fund invests are primarily below investment grade instruments, commonly referred to as “high yield” securities or “junk bonds.”

Under normal market conditions, the Fund may also:

•

Invest up to 10% of its Managed Assets through purchasing revolving credit facilities, investment grade debtor-in-possession financing, unsecured loans, other floating rate debt securities, such as notes, bonds, and asset-backed securities (such as collateralized loan obligations (“CLOs”)), investment grade loans and fixed income debt obligations of any maturity, money market instruments, such as commercial paper, and publicly-traded high yield debt securities.

•

Invest up to 10% of its Managed Assets in securities of:

Firms that, at the time of acquisition, have defaulted on their debt obligations and/or filed for protection under Chapter 11 of the U.S. Bankruptcy Code or have entered into a voluntary reorganization in conjunction with their creditors and stakeholders in order to avoid a bankruptcy filing; or

Firms prior to an event of default whose acute operating and/or financial problems have resulted in the markets valuing their respective securities and debt at sufficiently discounted prices so as to be yielding, should they not default, a significant premium over comparable duration U.S. Treasury bonds.

These foregoing investments are comprised of Senior Loans and, on limited occasions, equity and debt securities acquired in connection therewith.

•

Invest up to 15% of its Managed Assets in U.S. dollar-denominated foreign investments, exclusively in developed countries and territories of those countries, but in no case will the Fund invest in securities of issuers located in emerging markets.

It is anticipated that at least 80% of the Fund’s Managed Assets are invested in lower grade debt instruments, although from time to time all of the Fund’s Managed Assets may be invested in such lower grade debt instruments. The Fund may consider an expected

Page 33

First Trust Senior Floating Rate Income Fund II (FCT)

May 31, 2025 (Unaudited)

rating provided by a nationally recognized statistical rating organization (“NRSRO”) as if it were a final rating. The Fund’s investments in debt instruments may have fixed or variable principal payments and all types of interest rate and reset terms, including, but not limited to, fixed rate, adjustable rate, zero coupon, contingent, deferred, payment-in-kind and auction rate features.

The Fund does not intend to purchase publicly-traded equity securities but may receive such securities as a result of a restructuring of the debt of the issuer or the reorganization of a Senior Loan or as part of a package of securities acquired together with the Senior Loans of an issuer.

The Fund may enter into certain derivative transactions to seek to manage the risks of the Fund’s portfolio securities and certain of these derivative transactions may provide investment leverage to the Fund’s portfolio. The Fund does not enter into derivative transactions as a principal part of its investment strategy.

“Managed Assets” means the gross asset value of the Fund (including assets attributable to the Fund’s preferred shares of beneficial interest (“Preferred Shares”), if any, and the principal amount of borrowings) minus the sum of the Fund’s accrued and unpaid dividends on any outstanding Preferred Shares and accrued liabilities (other than the principal amount of any borrowings incurred or of commercial paper or notes issued by the Fund). For purposes of determining Managed Assets, the liquidation preference of Preferred Shares is not treated as a liability. Percentage limitations described herein are as of the time of investment by the Fund and may be exceeded on a going-forward basis as a result of market value fluctuations of the Fund’s portfolio and other events.

The Fund’s investment objectives are considered fundamental and may not be changed without shareholder approval. The remainder of the Fund’s investment policies, including its investment strategy, are considered non-fundamental and may be changed by the Board of Trustees without shareholder approval. The Fund will provide investors with at least 60 days’ prior notice of any change in the Fund’s investment strategy. There can be no assurance that the Fund’s investment objectives will be achieved.

Fundamental Investment Policies

The Fund, as a fundamental policy, may not:

1. With respect to 75% of its total assets, purchase any securities, if as a result more than 5% of the Fund’s total assets would then be invested in securities of any single issuer or if, as a result, the Fund would hold more than 10% of the outstanding voting securities of any single issuer; provided, that Government securities (as defined in the Investment Company Act of 1940 (the “1940 Act”)), securities issued by other investment companies and cash items (including receivables) shall not be counted for purposes of this limitation.

2. Purchase any security if, as a result of the purchase, 25% or more of the Fund’s total assets (taken at current value) would be invested in the securities of Borrowers and other issuers having their principal business activities in the same industry; provided, that this limitation shall not apply with respect to obligations issued or guaranteed by the U.S. Government or by its agencies or instrumentalities.

3. Borrow money, except as permitted by the 1940 Act, the rules thereunder and interpretations thereof or pursuant to a Commission exemptive order.

4. Issue senior securities, as defined in the 1940 Act, other than: (i) preferred shares which immediately after issuance will have asset coverage of at least 200%; (ii) indebtedness which immediately after issuance will have asset coverage of at least 300%; (iii) the borrowings permitted by investment restriction 3 above, or (iv) pursuant to a Commission exemptive order.

5. Make loans of money or property to any person, except for obtaining interests in Senior Loans in accordance with its investment objectives, through loans of portfolio securities or the acquisition of securities subject to repurchase agreements, or pursuant to a Commission rule or exemptive order.

6. Act as an underwriter of securities, except to the extent the Fund may be deemed to be an underwriter in certain cases when disposing of its portfolio investments or acting as an agent or one of a group of co-agents in originating Senior Loans.

7. Purchase or sell real estate, commodities or commodities contracts except pursuant to the exercise by the Fund of its rights under loan agreements, bankruptcy or reorganization, or pursuant to a Commission rule or exemptive order, and except to the extent the interests in Senior Loans the Fund may invest in are considered to be interests in real estate, commodities or commodities contracts and except to the extent that hedging instruments the Fund may invest in are considered to be commodities or commodities contracts.

For purposes of fundamental investment restriction numbers 1 and 2 above, the Fund treats the Lender selling a participation and any persons interpositioned between the Lender and the Fund as an issuer. The Fund may incur borrowings and/or issue series of notes or

Page 34

Investment Objectives, Policies, Risks and Effects of Leverage (Continued)

First Trust Senior Floating Rate Income Fund II (FCT)

May 31, 2025 (Unaudited)

other senior securities in an amount up to 33-1/3% (or such other percentage to the extent permitted by the 1940 Act) of its total assets (including the amount borrowed) less all liabilities other than borrowings.

Principal Risks

The Fund is a closed-end management investment company designed primarily as a long-term investment and not as a trading vehicle. The Fund is not intended to be a complete investment program and, due to the uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objectives. The following discussion summarizes the principal risks associated with investing in the Fund, which includes the risk that you could lose some or all of your investment in the Fund. The Fund is subject to the informational requirements of the Securities Exchange Act of 1934 and the Investment Company Act of 1940 and, in accordance therewith, files reports, proxy statements and other information that is available for review. The order of the below risk factors does not indicate the significance of any particular risk factor.

Credit Agency Risk. Credit ratings are determined by credit rating agencies and are only the opinions of such entities. Ratings assigned by a rating agency are not absolute standards of credit quality and do not evaluate market risk or the liquidity of securities. Any shortcomings or inefficiencies in credit rating agencies’ processes for determining credit ratings may adversely affect the credit ratings of securities held by the Fund or such credit rating agency’s ability to evaluate creditworthiness and, as a result, may adversely affect those securities’ perceived or actual credit risk.

Credit and Below-Investment Grade Securities Risk. Credit risk is the risk that the issuer or other obligated party of a debt security in the Fund’s portfolio will fail to pay, or it is perceived that it will fail to pay, dividends or interest and/or repay principal, when due. Below-investment grade instruments, including instruments that are not rated but judged to be of comparable quality, are commonly referred to as high-yield securities or “junk” bonds and are considered speculative with respect to the issuer’s capacity to pay dividends or interest and repay principal and are more susceptible to default or decline in market value than investment grade securities due to adverse economic and business developments. High-yield securities are often unsecured and subordinated to other creditors of the issuer. The market values for high-yield securities tend to be very volatile, and these securities are generally less liquid than investment grade securities. For these reasons, an investment in the Fund is subject to the following specific risks: (i) increased price sensitivity to changing interest rates and to a deteriorating economic environment; (ii) greater risk of loss due to default or declining credit quality; (iii) adverse company specific events more likely to render the issuer unable to make dividend, interest and/or principal payments; (iv) negative perception of the high-yield market which may depress the price and liquidity of high-yield securities; (v) volatility; and (vi) liquidity.

Current Market Conditions Risk. Current market conditions risk is the risk that a particular investment, or shares of the Fund in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial

Page 35

Investment Objectives, Policies, Risks and Effects of Leverage (Continued)

First Trust Senior Floating Rate Income Fund II (FCT)

May 31, 2025 (Unaudited)

markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets.

Cyber Security Risk. The Fund is susceptible to potential operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding, but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the Fund’s third-party service providers, such as its administrator, transfer agent or custodian, or issuers in which the Fund invests, can also subject the Fund to many of the same risks associated with direct cyber security breaches. The Fund has established risk management systems designed to reduce the risks associated with cyber security. However, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third party service providers. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future.

Financial Companies Risk. The Fund may invest in financial companies. Financial companies are subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge, the amount and types of capital they must maintain and, potentially, their size. Governmental regulation may change frequently and may have significant adverse consequences for financial companies, including effects not intended by such regulation. The impact of more stringent capital requirements, or recent or future regulation in various countries, on any individual financial company or on financial companies as a whole cannot be predicted. Certain risks may impact the value of investments in financial companies more severely than those of investments in other issuers, including the risks associated with companies that operate with substantial financial leverage. Financial companies may also be adversely affected by volatility in interest rates, loan losses and other customer defaults, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Insurance companies in particular may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. Financial companies are also a target for cyber attacks and may experience technology malfunctions and disruptions as a result.

Health Care Companies Risk. Through the Fund’s investments in senior loans, the Fund may be significantly exposed to companies in the health care sector. Health care companies are involved in medical services or health care, including biotechnology research and production, drugs and pharmaceuticals and health care facilities and services. These companies are subject to extensive competition, generic drug sales or the loss of patent protection, product liability litigation and increased government regulation. Research and development costs of bringing new drugs to market are substantial, and there is no guarantee that the product will ever come to market. Health care facility operators may be affected by the demand for services, efforts by government or insurers to limit rates, restriction of government financial assistance and competition from other providers.

Illiquid Securities Risk. The Fund invests a substantial portion of its assets in lower-quality debt issued by companies that are highly leveraged. Lower-quality debt tends to be less liquid than higher-quality debt. Moreover, smaller debt issues tend to be less liquid than larger debt issues. Although the resale or secondary market for senior loans is growing, it is currently limited. There is no organized exchange or board of trade on which senior loans are traded. Instead, the secondary market for senior loans is an unregulated inter-dealer or inter-bank resale market. In addition, senior loans in which the Fund invests may require the consent of the borrower and/or agent prior to the settlement of the sale or assignment. These consent requirements can delay or impede the Fund’s ability to settle the sale of senior loans. Depending on market conditions, the Fund may have difficulty disposing its senior loans, which may adversely impact its ability to obtain cash to repay debt, to pay dividends, to pay expenses or to take advantage of new investment opportunities.

Illiquid securities may be difficult to dispose of at a fair price at the times when the Fund believes it is desirable to do so. The market price of illiquid securities generally is more volatile than that of more liquid securities, which may adversely affect the price that the Fund pays for or recovers upon the sale of such securities. Illiquid securities are also more difficult to value, especially in challenging markets.

Information Technology Companies Risk. Information technology companies produce and provide hardware, software and information technology systems and services. Information technology companies are generally subject to the following risks: rapidly changing technologies and existing product obsolescence; short product life cycles; fierce competition; aggressive pricing and reduced

Page 36

May 31, 2025 (Unaudited)

profit margins; the loss of patent, copyright and trademark protections; cyclical market patterns; evolving industry standards; and frequent new product introductions and new market entrants. Information technology companies may be smaller and less experienced companies, with limited product lines, markets or financial resources and fewer experienced management or marketing personnel. Information technology company stocks, particularly those involved with the internet, have experienced extreme price and volume fluctuations that are often unrelated to their operating performance. In addition, information technology companies are particularly vulnerable to federal, state and local government regulation, and competition and consolidation, both domestically and internationally, including competition from foreign competitors with lower production costs. Information technology companies also face competition for services of qualified personnel and heavily rely on patents and intellectual property rights and the ability to enforce such rights to maintain a competitive advantage.

Interest Rate Risk. The yield on the Fund’s common shares may rise or fall as market interest rates rise and fall, as senior loans pay interest at rates which float in response to changes in market rates. Changes in prevailing interest rates can be expected to cause some fluctuation in the Fund’s net asset value. Similarly, a sudden and significant increase in market interest rates may cause a decline in the Fund’s net asset value.

Leverage Risk. The use of leverage by the Fund can magnify the effect of any losses. If the income and gains from the securities and investments purchased with leverage proceeds do not cover the cost of leverage, the return to the common shares will be less than if leverage had not been used. Leverage involves risks and special considerations for common shareholders including: (i) the likelihood of greater volatility of net asset value and market price of the common shares than a comparable portfolio without leverage; (ii) the risk that fluctuations in interest rates on borrowings will reduce the return to the common shareholders or will result in fluctuations in the dividends paid on the common shares; (iii) in a declining market, the use of leverage is likely to cause a greater decline in the net asset value of the common shares than if the Fund were not leveraged, which may result in a greater decline in the market price of the common shares; and (iv) when the Fund uses certain types of leverage, the investment advisory fee payable to the Advisor will be higher than if the Fund did not use leverage.

Management Risk and Reliance on Key Personnel. The implementation of the Fund’s investment strategy depends upon the continued contributions of certain key employees of the Advisor, some of whom have unique talents and experience and would be difficult to replace. The loss or interruption of the services of a key member of the portfolio management team could have a negative impact on the Fund.

Market Discount from Net Asset Value. Shares of closed-end investment companies such as the Fund frequently trade at a discount from their net asset value. The Fund cannot predict whether its common shares will trade at, below or above net asset value.

Market Risk. Investments held by the Fund, as well as shares of the Fund itself, are subject to market fluctuations caused by real or perceived adverse economic conditions, political events, regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments as a result of the risk of loss associated with these market fluctuations. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares, the liquidity of an investment, and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on the Fund’s shares may widen and the returns on investment may fluctuate.

Non-U.S. Securities Risk. The Fund may invest a portion of its assets in securities of non-U.S. issuers. Investing in securities of non-U.S. issuers may involve certain risks not typically associated with investing in securities of U.S. issuers. These risks include: (i) there may be less publicly available information about non-U.S. issuers or markets due to less rigorous disclosure or accounting standards or regulatory practices; (ii) non-U.S. markets may be smaller, less liquid and more volatile than the U.S. market; (iii) potential adverse effects of fluctuations in currency exchange rates or controls on the value of the Fund’s investments; (iv) the economies of non-U.S. countries may grow at slower rates than expected or may experience a downturn or recession; (v) the impact of economic, political, social or diplomatic events; (vi) certain non-U.S. countries may impose restrictions on the ability of non-U.S. issuers to make payments of principal and interest to investors located in the United States due to blockage of non-U.S. currency exchanges or otherwise; and (vii) withholding and other non-U.S. taxes may decrease the Fund’s return. Foreign companies are generally not subject to the same accounting, auditing and financial reporting standards as are U.S. companies. In addition, there may be difficulty in obtaining or enforcing a court judgment abroad. These risks may be more pronounced to the extent that the Fund invests a significant amount of its assets in companies located in one region.

Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate

Page 37

Investment Objectives, Policies, Risks and Effects of Leverage (Continued)

First Trust Senior Floating Rate Income Fund II (FCT)

May 31, 2025 (Unaudited)

processes and technology or systems failures. The Fund relies on third parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and the Advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

Potential Conflicts of Interest Risk. First Trust and the portfolio managers have interests which may conflict with the interests of the Fund. In particular, First Trust currently manages and may in the future manage and/or advise other investment funds or accounts with the same or substantially similar investment objectives and strategies as the Fund. In addition, while the Fund is using leverage, the amount of the fees paid to First Trust for investment advisory and management services are higher than if the Fund did not use leverage because the fees paid are calculated based on managed assets. Therefore, First Trust has a financial incentive to leverage the Fund.

Prepayment Risk. Loans are subject to prepayment risk. Prepayment risk is the risk that the borrower on a loan will repay principal (in part or in whole) prior to the scheduled maturity date. The degree to which borrowers prepay loans, whether as a contractual requirement or at their election, may be affected by general business conditions, interest rates, the financial condition of the borrower and competitive conditions among loan investors, among others. As such, prepayments cannot be predicted with accuracy. Upon a prepayment, either in part or in full, the actual outstanding debt on which the Fund derives interest income will be reduced. The Fund may not be able to reinvest the proceeds received on terms as favorable as the prepaid loan.

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if the Fund invests the proceeds from matured, traded or called instruments at market interest rates that are below the Fund’s portfolio’s current earnings rate. A decline in income could affect the common shares’ market price, level of distributions or the overall return of the Fund.

Risks Associated with Investments in Distressed Issuers. The Fund may invest in instruments of distressed issuers, including firms that have defaulted on their debt obligations and/or filed for bankruptcy protection. Investing in such investments involves a far greater level of risk than investing in issuers whose debt obligations are being met and whose debt trades at or close to its “par” value. These investments are highly speculative with respect to the issuer’s ability to continue to make interest payments and/or to pay its principal obligations in full; can be very difficult to properly value, making them susceptible to a high degree of price volatility and rendering them less liquid than performing debt obligations; and, for issuers involved in a bankruptcy proceeding, can be subject to a high degree of uncertainty with regard to both the timing and the amount of the ultimate settlement.

Second Lien Loan Risk. A second lien loan may have a claim on the same collateral pool as the first lien or it may be secured by a separate set of assets. Second lien loans are typically secured by a second priority security interest or lien on specified collateral securing the borrower’s obligation under the interest. Because second lien loans are second to first lien loans, they present a greater degree of investment risk. Specifically, these loans are subject to the additional risk that the cash flow of the borrower and property securing the loan may be insufficient to meet scheduled payments after giving effect to those loans with a higher priority. In addition, loans that have a lower than first lien priority on collateral of the borrower generally have greater price volatility than those loans with a higher priority and may be less liquid.

Senior Loan Risk. The Fund invests in senior loans and therefore is subject to the risks associated therewith. Investments in senior loans are subject to the same risks as investments in other types of debt securities, including credit risk, interest rate risk, liquidity risk and valuation risk (which may be heightened because of the limited public information available regarding senior loans and because loan borrowers may be leveraged and tend to be more adversely affected by changes in market or economic conditions). Further, no active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to sell a senior loan and which may make it difficult to value senior loans. Senior loans may not be considered “securities” and the Fund may not be entitled to rely on the anti-fraud protections of the federal securities laws.

In the event a borrower fails to pay scheduled interest or principal payments on a senior loan held by the Fund, the Fund will experience a reduction in its income and a decline in the value of the senior loan, which will likely reduce dividends and lead to a decline in the net asset value of the Fund’s common shares. If the Fund acquires a senior loan from another lender, for example, by acquiring a participation, the Fund may also be subject to credit risks with respect to that lender. Although senior loans may be secured by specific collateral, the value of the collateral may not equal the Fund’s investment when the senior loan is acquired or may decline below the principal amount of the senior loan subsequent to the Fund’s investment. Also, to the extent that collateral consists of stock of the borrower or its subsidiaries or affiliates, the Fund bears the risk that the stock may decline in value, be relatively illiquid, and/or may lose all or substantially all of its value, causing the senior loan to be under collateralized. Therefore, the liquidation of the collateral underlying a senior loan may not satisfy the issuer’s obligation to the Fund in the event of non-payment of scheduled interest or principal, and the collateral may not be readily liquidated. The senior loan market has seen a significant increase in loans with weaker lender protections including, but not limited to, limited financial maintenance covenants or, in some cases, no financial maintenance covenants (i.e., “covenant-lite loans”) that would typically be included in a traditional loan agreement and general

Page 38

Investment Objectives, Policies, Risks and Effects of Leverage (Continued)

First Trust Senior Floating Rate Income Fund II (FCT)

May 31, 2025 (Unaudited)

weakening of other restrictive covenants applicable to the borrower such as limitations on incurrence of additional debt, restrictions on payments of junior debt or restrictions on dividends and distributions. Weaker lender protections such as the absence of financial maintenance covenants in a loan agreement and the inclusion of “borrower-favorable” terms may impact recovery values and/or trading levels of senior loans in the future. The absence of financial maintenance covenants in a loan agreement generally means that the lender may not be able to declare a default if financial performance deteriorates. This may hinder the Fund’s ability to reprice credit risk associated with a particular borrower and reduce the Fund’s ability to restructure a problematic loan and mitigate potential loss. As a result, the Fund’s exposure to losses on investments in senior loans may be increased, especially during a downturn in the credit cycle or changes in market or economic conditions.

Valuation Risk. The valuation of senior loans may carry more risk than that of common stock. Because the secondary market for senior loans is limited, it may be difficult to value the loans held by the Fund. Market quotations may not be readily available for some senior loans and valuation may require more research than for liquid securities. In addition, elements of judgment may play a greater role in the valuation of senior loans than for securities with a secondary market, because there is less reliable objective data available. These difficulties may lead to inaccurate asset pricing.

Effects of Leverage

The aggregate principal amount of borrowings under the credit agreement (the “Credit Agreement”) with The Toronto-Dominion Bank, New York Branch represented approximately 16.42% of Managed Assets as of May 31, 2025. Asset coverage with respect to the borrowings was 609.02% as of May 31, 2025 and the Fund had $66,000,000 of unutilized funds available for borrowing under the Credit Agreement as of that date. As of May 31, 2025, the maximum commitment amount of the Credit Agreement was $120,000,000. As of May 31, 2025, the approximate average annual interest and fee rate was 5.80%.

Assuming that the Fund’s leverage costs remain as described above (at an assumed average annual cost of 5.80%), the annual return that the Fund’s portfolio must experience (net of expenses) in order to cover its leverage costs would be 0.95%.

The following table is furnished in response to requirements of the Securities and Exchange Commission (“SEC”). It is designed to illustrate the effect of leverage on Common Share total return, assuming investment portfolio total returns (comprised of income and changes in the value of securities held in the Fund’s portfolio) of (10%), (5%), 0%, 5% and 10%. These assumed investment portfolio returns are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund.

The table further assumes leverage representing 16.42% of the Fund’s Managed Assets, net of expenses, and an annual leverage interest and fee rate of 5.80%.

Assumed Portfolio Total Return (Net of Expenses)	-10 %	-5 %	0 %	5 %	10 %
Common Share Total Return	-13.10 %	-7.12 %	-1.14 %	4.84 %	10.83 %

Common share total return is composed of two elements: the common share dividends paid by the Fund (the amount of which is largely determined by the net investment income of the Fund after paying dividends or interest on its leverage instruments) and gains or losses on the value of the securities the Fund owns. As required by SEC rules, the table above assumes that the Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0% the Fund must assume that the interest it receives on its debt security investments is entirely offset by losses in the value of those investments.

If the independent auditor has provided non-audit services to the Registrant’s advisor (other than any sub-advisor whose role is primarily portfolio management and is sub-contracted with or overseen by another investment advisor) and any entity controlling, controlled by or under common control with the investment advisor that provides ongoing services to the Registrant that were not pre-approved pursuant to its policies, the Committee will consider whether the provision of such non-audit services is compatible with the auditor’s independence.

Registrant:		Advisor and Distributor:

(g)

The aggregate non-audit fees billed by the Registrant’s accountant for services rendered to the Registrant, and rendered to the Registrant’s investment advisor (not including any sub-advisor whose role is primarily portfolio management and is subcontracted with or overseen by another investment advisor), and any entity controlling, controlled by, or under common control with the advisor that provides ongoing services to the Registrant for the fiscal year ended 2024 were $14,267 for the Registrant, $28,600 for the Registrant’s investment advisor and $0 for the Registrant’s distributor; and for the fiscal year ended 2025 were $21,391 for the Registrant, $28,080 for the Registrant’s investment advisor and $0 for the Registrant’s distributor.

(h)

The Registrant’s audit committee of its Board of Trustees has determined that the provision of non-audit services that were rendered to the Registrant’s investment advisor (not including any sub-advisor whose role is primarily portfolio management and is subcontracted with or overseen by another investment advisor), and any entity controlling, controlled by, or under common control with the investment advisor that provides ongoing services to the Registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant’s independence.

Potential Conflicts of Interests

Potential conflicts of interest may arise when a portfolio manager of the Registrant has day-to-day management responsibilities with respect to one or more other funds or other accounts. The First Trust Advisors Leveraged Finance Investment Team adheres to its trade allocation policy utilizing a pro-rata methodology to address this conflict. First Trust and its affiliate, First Trust Portfolios L.P. ("FTP''), have in place a joint Code of Ethics and Insider Trading Policies and Procedures that are designed to (a) prevent First Trust personnel from trading securities based upon material inside information in the possession of such personnel and (b) ensure that First Trust personnel avoid actual or potential conflicts of interest or abuse of their positions of trust and responsibility that could occur through such activities as front running securities trades for the Registrant. Personnel are required to have duplicate confirmations and account statements delivered to First Trust and FTP compliance personnel who then compare such trades to trading activity to detect any potential conflict situations. In addition to the personal trading restrictions specified in the Code of Ethics and Insider Trading Policies and Procedures, employees in the First Trust Advisors Leveraged Finance Investment Team are prohibited from buying or selling equity securities (including derivative instruments such as options, warrants and futures) and corporate bonds for their personal account and in any accounts over which they exercise control. Employees in the First Trust Advisors Leveraged Finance Investment Team are also prohibited from engaging in any personal transaction while in possession of material non-public information regarding the security or the issuer of the security. First Trust and FTP also maintain a restricted list of all issuers for which the First Trust Advisors Leveraged Finance Investment Team has material non-public information in its possession and all transactions executed for a product advised or supervised by First Trust or FTP are compared daily against the restricted list.

Bonuses are also determined by management and are generally based upon an individual’s or team’s overall contribution to the success of the firm, assets under management and the profitability of the firm.
