Management's discussion of fund performance

MANAGED BY

Long Hoang, Daniel A. Walker, Adam Wise, and Ying Yi

Despite strong optimism at the start of the year for increased M&A activity, middle market direct lending deal flow for sponsor backed companies ultimately declined by approximately 12%. The slowdown was driven primarily by unexpected policy shocks, elevated market volatility, and continued uncertainty around the timing and trajectory of rate cuts. In this supply constrained environment, direct lenders operated within an increasingly competitive landscape, resulting in tighter spreads and more borrower friendly terms.

Nevertheless, market participants enter 2026 with renewed optimism, having navigated another year of volatility and underwhelming M&A activity. As we look ahead, several themes will be top of mind: the volume of true new money transactions, greater clarity around the interest rate path, the pace of refinancing and amend and extend activity as near term maturities approach, the intensity of competition-particularly whether it remains concentrated in top tier credits-and, finally, the velocity at which limited partners deploy fresh year capital, including interest in co-investments and larger ticket sizes.

John Hancock GA Senior Loan Trust returned 8.38% for the year ended December 31, 2025, outperforming its benchmark, the Morningstar LSTA U.S. B Ratings Loan Index, which returned 6.18%. The fund's outperformance was driven primarily by the more pronounced spread compression that occurred in the broadly syndicated loan market in 2025, as Collateralized Loan Obligation demand significantly outpaced new issue supply.

The views expressed in this report are exclusively those of Manulife Investment Management Private Markets (US) LLC, and are subject to change. They are not meant as investment advice. Please note that the holdings discussed in this report, if any, may not have been held by the fund for the entire period. Portfolio composition is subject to review in accordance with the fund's investment strategy and may vary in the future. Current and future portfolio holdings are subject to risk.

Performance figures assume all distributions have been reinvested.

The returns reflect past results and should not be considered indicative of future performance. Investment returns and principal value will fluctuate and a shareholder may sustain losses. Current performance may be higher or lower than the performance cited.

The performance table above and the chart on the next page do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the sale of fund shares. The fund's performance results reflect any applicable fee waivers or expense reductions, without which the expenses would increase and results would have been less favorable.

It is not possible to invest directly in an index. Index figures do not reflect expenses, which would result in lower returns.

John Hancock GA Senior Loan Trust

Notes to consolidated financial statements 12-31-25

1. Organization

John Hancock GA Senior Loan Trust (the fund) is a Delaware statutory trust that is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a closed-end management investment company. The investment objective of the fund is to generate current income.

The fund is only offered to "accredited investors" within the meaning of Regulation D under the Securities Act of 1933, as amended (the 1933 Act), non-U.S. investors within the meaning of Regulation S under the 1933 Act, and other investors eligible to invest in a private placement.

Basis of consolidation. The accompanying consolidated financial statements include the accounts of John Hancock GA Senior Loan Subsidiary Trust LLC (the subsidiary), which was incorporated on October 10, 2024, and is a wholly-owned subsidiary of the fund. The fund and its subsidiary are advised by Manulife Investment Management Private Markets (US) LLC (the Advisor). As of December 31, 2025, the net assets of the subsidiary were $3,939,617 representing 0.41% of the fund's consolidated net assets. Intercompany accounts and transactions, if any, have been eliminated. The consolidated fund's investments include positions of the fund and the subsidiary.

2. Significant accounting policies

The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (US GAAP), which require management to make certain estimates and assumptions as of the date of the consolidated financial statements. Actual results could differ from those estimates and those differences could be significant. The fund qualifies as an investment company under Topic 946 of Accounting Standards Codification (ASC) of US GAAP.

Events or transactions occurring after the end of the fiscal period through the date that the consolidated financial statements were issued have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the fund:

Security valuation. Investments are valued at the end of each month at a minimum. The fund invests primarily in senior loans. The Advisor, assisted by its Pricing Committee (composed of officers of the Advisor and its affiliates), determines the fair value of the fund's securities that are not publicly traded or whose market prices are not readily available pursuant to procedures established by the Advisor and adopted by the Board of Trustees. In connection with that determination, portfolio valuations are prepared in accordance with the Advisor's valuation policy using valuation obtained from independent valuation firms and/or proprietary models.

Valuation techniques include discounted cash flow models, comparison with similar instruments for which observable market prices exist and other valuation models. Assumptions and inputs used in valuation techniques include risk-free and benchmark interest rates, credit spreads and other inputs used in estimating discount rates. For senior loans, the fund uses valuations from independent valuation firms, which are based on models developed from recognized US GAAP valuation approaches under ASC 820. Some or all of the significant inputs into these models may be unobservable and are derived either from observable market prices or rates or are estimated based on unobservable assumptions. Valuation models that employ significant unobservable inputs require a higher degree of management judgment and estimation in the determination of fair value. Judgment and estimation are usually required for the selection of the appropriate valuation model to be used, determination of expected future cash flows on the financial instrument being valued, determination of the probability of counterparty default and prepayments and selection of appropriate discount rates.

Equity securities are generally valued at the last sale price or, for certain markets, the official closing price as of the close of the relevant exchange. Securities not traded on a particular day are valued using last available bid prices. A security that is listed or traded on more than one exchange is typically valued at the

25

John Hancock GA Senior Loan Trust

Notes to consolidated financial statements 12-31-25

price on the exchange where the security was acquired or most likely will be sold. In certain instances, the Pricing Committee may determine to value equity securities using prices obtained from another exchange or market if trading on the exchange or market on which prices are typically obtained did not open for trading as scheduled, or if trading closed earlier than scheduled, and trading occurred as normal on another exchange or market.

The Pricing Committee engages in oversight activities with respect to pricing vendors, which includes, among other things, back-testing of pricing vendor prices against actual trades, conducting periodic due diligence meetings and reviews, and periodically reviewing the inputs, assumptions and methodologies used by these vendors. Nevertheless, market quotations, official closing prices, or information furnished by a pricing vendor could be inaccurate, which could lead to a security being valued incorrectly.

The fund uses a three-tier hierarchy to prioritize the pricing assumptions, referred to as inputs, used in valuation techniques to measure fair value. Level 1 includes securities valued using quoted prices in active markets for identical securities. Level 2 includes securities valued using other significant observable inputs. Observable inputs may include quoted prices for similar securities, interest rates, prepayment speeds and credit risk. Prices for securities valued using these inputs are received from independent pricing vendors and brokers and are based on an evaluation of the inputs described. Level 3 includes securities valued using significant unobservable inputs when market prices are not readily available or reliable, including the Advisor's own assumptions in determining the fair value of investments. Factors used in determining value may include market or issuer specific events or trends, changes in interest rates and credit quality. The inputs or methodology used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. Changes in valuation techniques and related inputs may result in transfers into or out of an assigned level within the disclosure hierarchy.

Senior loan investments are measured at fair value based on the present value of the expected cash flows of the loans. There are no quoted prices in active markets. Assumptions and inputs used in the valuation of senior loan investments include prepayment estimates, determination of the discount rate based on the risk-free interest rate adjusted for credit risk (including estimation of probability of default), liquidity and any other adjustments that the independent valuation firm believes that a third-party market participant would take into account in pricing a transaction. Senior loan investment valuations rely primarily on the use of significant unobservable inputs, including credit assumptions, which require significant judgment and, accordingly, are classified as Level 3.

Other debt obligations are typically valued based on the evaluated prices provided by an independent pricing vendor. Independent pricing vendors utilize matrix pricing which takes into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data, as well as broker supplied prices. Other debt obligations are generally classified as Level 2.

Equity investments that do not have a counterparty trading in public market will be fair valued as determined in good faith by the Pricing Committee following procedures established by the Advisor and adopted by the Board of Trustees. Private equities rely primarily on the use of significant unobservable inputs, which require significant judgment and, accordingly, are classified as Level 3.

Investments in open-end mutual funds are valued at their respective net asset values each business day and are generally classified as Level 1.

Due to the inherent uncertainty of determining the fair value of Level 3 investments, the fair value of the investments may differ significantly from the values that would have been used had a ready market for such securities existed and may differ materially from the values that may ultimately be received or settled. Further, such investments will generally be subject to legal and other restrictions, or otherwise will be less liquid than publicly traded instruments. If the fund is required to liquidate a portfolio investment in a forced or liquidation sale, the fund might realize significantly less than the value at which such investment will have been previously been recorded. The fund's investments will be subject to market risk. Market risk is the potential for changes in the value due to market changes. Market risk is directly impacted by the volatility and liquidity in the markets in which the investments are traded.

Senior loans. The fund invests in senior loans. Senior loans include first and second lien term loans, delayed draw term loans, and revolving credit facilities. The fund will only invest in loans and commitments that are determined to be below investment-grade. The fund's investment policies are based on credit quality at the time of purchase. Credit quality is determined by the Advisor. The fund may invest in loans with a maturity of up to nine years from the closing date of the loan. The Advisor typically expects to employ a buy-and-hold strategy. The fund may invest in loans either by transacting directly at the initial funding date or acquiring loans in secondary market transactions. The fund may invest in loans secured by substantially all of the assets of the borrower and the other loan parties, subject to customary exceptions, including a pledge of the equity of the borrower and its subsidiaries.

The fund may be subject to greater levels of credit risk, call (or prepayment) risk, settlement risk and liquidity risk than funds that do not invest in senior loans. Senior loans are considered predominantly speculative with respect to an issuer's continuing ability to make principal and interest payments, and may be more volatile than other types of securities. An economic downturn or individual corporate developments could adversely affect the market for these instruments and reduce the fund's ability to sell these instruments at an advantageous time or price. An economic downturn would generally lead to a higher non-payment rate and a senior loan may lose significant value before a default occurs. The fund may also be subject to greater levels of liquidity risk than funds that do not invest in senior loans. In addition, the senior loans in which the fund invests may not be listed on any exchange and a secondary market for such loans may be comparatively less liquid relative to markets for other more liquid fixed income securities. Consequently, transactions in senior loans may involve greater costs than transactions in more actively traded securities. Restrictions on transfers in loan agreements, a lack of publicly-available information, irregular trading activity and wide bid/ask spreads among other factors, may, in certain circumstances, make senior loans difficult to value accurately or sell at an advantageous time or price than other types of securities or instruments. These factors may result in the fund being unable to realize full value for the senior loans and/or may result in the fund not receiving the proceeds from a sale of a senior loan for an extended period after such sale, each of which could result in losses to the fund. Senior loans may have extended trade settlement periods which may result in cash not being immediately available to the fund. If an issuer of a senior loan prepays or redeems the loan prior to maturity, the fund may have to reinvest the proceeds in other senior loans or similar instruments that may pay lower interest rates. Senior loans in which the fund invests may or may not be collateralized, although the loans may not be fully collateralized and the collateral may be unavailable or insufficient to meet the obligations of the borrower. The fund may have limited rights to exercise remedies against such collateral or a borrower, and loan agreements may impose certain procedures that delay receipt of the proceeds of collateral or require the fund to act collectively with other creditors to exercise its rights with respect to a senior loan. Because of the risks involved in investing in senior loans, an investment in the fund should be considered speculative. Junior loans, which are secured and unsecured subordinated

28

John Hancock GA Senior Loan Trust

Notes to consolidated financial statements 12-31-25

loans, second lien loans and subordinate bridge loans, involve a higher degree of overall risk than senior loans of the same borrower due to the junior loan's lower place in the borrower's capital structure and, in some cases, their unsecured status.

The fund may also enter into, or acquire participations in, delayed funding loans and revolving credit facilities, in which a bank or other lender agrees to make loans up to a maximum amount upon demand by the borrower during a specified term. These commitments may have the effect of requiring the fund to increase its investment in a company at a time when it might not be desirable to do so (including at a time when the company's financial condition makes it unlikely that such amounts will be repaid). Delayed funding loans and revolving credit facilities are subject to credit, interest rate and liquidity risk and the risks of being a lender. Unfunded loan commitments are marked to market in accordance with the fund's valuation policies. Any related unrealized appreciation (depreciation) on unfunded commitments is included in unaffiliated investments, at value in the Consolidated statement of assets and liabilities and change in net unrealized appreciation (depreciation) in the Consolidated statement of operations. As of December 31, 2025, the fund had the following unfunded commitments outstanding.

Security transactions and related investment income. Investment security transactions are accounted for on a trade date plus one basis for NAV calculations. However, for financial reporting purposes, investment transactions are reported on trade date. Interest income is accrued as earned. Interest income includes coupon interest and amortization/accretion of premiums/discounts on debt securities. Debt obligations may be placed in a non-accrual status and related interest income may be reduced by stopping current accruals and writing off interest receivable when the collection of all or a portion of interest has become doubtful. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds from litigation.

Overdrafts. Pursuant to the custodian agreement, the fund's custodian may, in its discretion, advance funds to the fund to make properly authorized payments. When such payments result in an overdraft, the fund is obligated to repay the custodian for any overdraft, including any costs or expenses associated with the overdraft. The custodian may have a lien, security interest or security entitlement in any fund property that is not otherwise segregated or pledged, to the maximum extent permitted by law, to the extent of any overdraft. Overdrafts at period end, if any, are presented under the caption Due to custodian in the Consolidated statement of assets and liabilities.

Line of credit. The fund has entered into a revolving promissory note agreement with John Hancock Funding Company, LLC (JH Funding) and a Line of Credit agreement with John Hancock Life Insurance Company (JHUSA). The aggregate outstanding borrowings under the agreements with both JHUSA and JH Funding for the fund will not exceed $350 million. Any borrowings will be first drawn from JHUSA up to $50 million, subject to certain conditions as specified in the agreement; otherwise, the borrowings will be drawn from JH Funding. Prior to February 18, 2025, aggregate outstanding borrowings under the agreements would not exceed $250 million. There were no upfront fees or commitment fees paid by the fund in connection with these line of credit agreements. The borrowings under these agreements are designed to be short-term to satisfy intermittent delayed draws and will not be used to originate new loans or for investment leverage. For the year ended December 31, 2025, the fund had no borrowings under the line of credit.

Expenses. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Consolidated statement of cash flows. A Consolidated statement of cash flows is presented when a certain percentage of the fund's investments is classified as Level 3 in the fair value hierarchy. Information on financial transactions that have been settled through the receipt and disbursement of cash is presented in the Consolidated statement of cash flows. The cash amount shown in the Consolidated statement of cash flows is the amount included in the fund's Consolidated statement of assets and liabilities and represents the cash on hand at the fund's custodian and does not include any short-term investments.

Notes to consolidated financial statements 12-31-25

Federal income taxes. The fund intends to continue to qualify as a regulated investment company by complying with the applicable provisions of the Internal Revenue Code and will not be subject to federal income tax on taxable income that is distributed to shareholders. Therefore, no federal income tax provision is required.

For federal income tax purposes, as of December 31, 2025, the fund has a long-term capital loss carryforward of $1,920,493 available to offset future net realized capital gains. These carryforwards do not expire.

As of December 31, 2025, the fund had no uncertain tax positions that would require consolidated financial statement recognition, derecognition or disclosure. The fund's federal tax returns are subject to examination by the Internal Revenue Service for a period of three years.

Distribution of income and gains. Distributions to shareholders from net investment income and net realized gains, if any, are recorded on the ex-date. The fund generally declares and pays dividends at least quarterly. Capital gain distributions, if any, are typically distributed annually.

The tax character of distributions for the years ended December 31, 2025 and 2024 was as follows:

December 31, 2025

December 31, 2024

Ordinary income

$75,878,444

$60,230,440

As of December 31, 2025, there were no distributable earnings on a tax basis.

Such distributions and distributable earnings, on a tax basis, if any, are determined in conformity with income tax regulations, which may differ from US GAAP. Distributions in excess of tax basis earnings and profits, if any, are reported in the fund's financial statements as a return of capital.

Capital accounts within the consolidated financial statements are adjusted for permanent book-tax differences at fiscal year end. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences, if any, will reverse in a subsequent period. Book-tax differences are primarily attributable to distributions payable.

3. Guarantees and indemnifications

Under the fund's organizational documents, its Officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the fund. Additionally, in the normal course of business, the fund enters into contracts with service providers that contain general indemnification clauses. The fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the fund that have not yet occurred. The risk of material loss from such claims is considered remote.

4. Fees and transactions with affiliates

The Advisor serves as investment advisor for the fund. The fund does not have a principal underwriter. The fund has entered into a Placement Agency Agreement with John Hancock Investment Management Distributors, LLC (the Distributor), an affiliate of the Advisor, to offer to sell shares of the fund. The Advisor is an indirect wholly-owned subsidiary of Manulife Financial Corporation (MFC), and the Distributor is an indirect, principally owned subsidiary of John Hancock Life Insurance Company (U.S.A.), which in turn is a subsidiary of MFC.

Management fee. The fund has an investment management agreement with the Advisor under which the fund pays an annual fee rate of 0.55% of the fund's average net assets.

Performance fee. The fund has an agreement with the Advisor under which the fund pays a performance fee at annual rate of 10% of the fund's net profits, if any, over the high water mark (as defined below) provided that the performance fee shall be due only if (and, to the extent necessary, shall be reduced by an

32

John Hancock GA Senior Loan Trust

Notes to consolidated financial statements 12-31-25

amount so that), after deducting such performance fee the fund's net profits as of the end of the applicable quarter will at least equal a defined preferred return (as defined below). For the purposes of calculating the performance fee, net profits will be determined by taking into account net realized gain or loss (including realized gain that has been distributed to shareholders during a fiscal quarter and net of fund expenses, including the management fee) and the net change in unrealized appreciation or depreciation of securities positions, as well as dividends, interest and other income. No performance fee will be payable for any fiscal quarter unless losses and depreciation from prior fiscal quarters (the "cumulative loss") have been recovered by the fund, which is referred to as a "high water mark" calculation. The cumulative loss to be recovered before payment of performance fees will be reduced in the event of withdrawals by shareholders. The Advisor is under no obligation to repay any performance fees previously paid by the fund. Thus, the payment of performance fee for a fiscal quarter will not be reversed by the subsequent decline of the fund's net asset value in any subsequent fiscal quarter.

The preferred return as of the end of the applicable fiscal quarter is an amount equal to (a) 1.25% (the "preferred return rate") multiplied by (b) the fund's net asset value as of the beginning of the fiscal quarter, adjusted to reflect additions to the fund's net asset value resulting from new share purchases during the fiscal quarter and reductions to the fund resulting from withdrawals by, or distributions to, shareholders during the fiscal quarter (the "preferred return base"). The performance fee is accrued monthly and paid quarterly.

Accounting and legal services. Pursuant to a service agreement, the fund reimburses the Advisor for all expenses associated with providing the administrative, financial, legal, compliance, accounting and recordkeeping services to the fund, including the preparation of all tax returns, periodic reports to shareholders and regulatory reports, among other services. These accounting and legal services fees incurred for the year ended December 31, 2025 amounted to an annual rate of 0.04% of the fund's average net assets.

Trustee expenses. The fund compensates each Trustee who is not an employee of the Advisor or its affiliates.

Co-investment. Pursuant to an Exemptive Order issued by the SEC, the fund is permitted to negotiate certain investments with entities with which it would be restricted from doing so under the 1940 Act, such as the Advisor and its affiliates. The fund is permitted to co-invest with affiliates if certain conditions are met. For example, the Advisor makes an independent determination of the appropriateness of the investment for the fund. Also, a "required majority" (as defined in the 1940 Act) of the fund's independent trustees make certain conclusions in connection with a co-investment transaction as set forth in the order, including that (1) the terms of the transactions, including the consideration to be paid, are reasonable and fair to the fund and shareholders and do not involve overreaching by the fund or shareholders on the part of any person concerned and (2) the transaction is consistent with the interests of shareholders and is consistent with the fund's investment objective and strategies. During the year ended December 31, 2025, commitments entered into by the fund pursuant to the exemptive order amounted to $387,735,022, including unfunded commitments of $127,386,655.

5. Fund share transactions

Affiliates of the fund owned 100% of shares of the fund on December 31, 2025.

6. Purchase and sale of securities

Purchases and sales of securities, other than short-term investments, amounted to $324,089,024 and $77,979,042, respectively, for the year ended December 31, 2025.

33

John Hancock GA Senior Loan Trust

Notes to consolidated financial statements 12-31-25

7. Segment reporting

The management committee of the Advisor acts as the fund's chief operating decision maker (the CODM),assessing performance and making decisions about resource allocation. The fund represents a single operating segment, as the CODM monitors and assesses the operating results of the fund as a whole, and the fund's long-term strategic asset allocation is managed in accordance with the terms of its prospectus, based on a defined investment strategy which is executed by the portfolio management team of the fund's subadvisor. Segment assets are reflected in the Consolidated statement of assets and liabilities as "Total assets", which consists primarily of total investments at value. The financial information, including the measurement of profit and loss and significant expenses, provided to and reviewed by the CODM is consistent with that presented within the Consolidated statement of operations, which includes "Increase (decrease) in net assets from operations", Consolidated statements of changes in net assets, which includes "Increase (decrease) in net assets from fund share transactions", and Consolidated financial highlights, which includes total return and income and expense ratios.

8. Subsequent event

Effective January 30, 2026, the aggregate outstanding borrowings under the revolving promissory note agreement with JH Funding and the Line of Credit agreement with JHUSA will not exceed $500 million.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Trustees of John Hancock GA Senior Loan Trust

Opinion on the Financial Statements

We have audited the accompanying consolidated statement of assets and liabilities of John Hancock GA Senior Loan Trust (the "Fund"), including the consolidated portfolio of investments, as of December 31, 2025, and the related consolidated statements of operations and cash flows for the year then ended, the consolidated statements of changes in net assets for each of the two years in the period then ended, the consolidated financial highlights for each of the five years in the period then ended and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the consolidated financial position of the Fund at December 31, 2025, the consolidated results of its operations and its cash flows for the year then ended, the consolidated changes in its net assets for each of the two years in the period then ended and its consolidated financial highlights for each of the five years in the period then ended in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements 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 in accordance with the relevant ethical requirements relating to our audits.

We conducted our audits in accordance with the auditing standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements 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 the Fund's 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, 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. Our procedures included confirmation of securities owned as of December 31, 2025, by correspondence with the custodian, brokers and others. 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. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more John Hancock investment companies since 2019.

Tax information

Unaudited

For federal income tax purposes, the following information is furnished with respect to the distributions of the fund, if any, paid during its taxable year ended December 31, 2025.

The fund reports the maximum amount allowable as Section 163(j) Interest Dividends.

Qualified Interest Income (QII)

Non Resident Alien (NRA) shareholders are normally subject to a 30% (or lower tax treaty rate depending on the country) NRA withholding tax on income and short-term capital gain dividends paid by a mutual fund, unless such dividends are designated as qualified interest income or qualified short-term capital gains, and therefore exempt from NRA withholding tax. Under the American Jobs Creation Act of 2004, the following percentages of ordinary dividends paid during the fiscal year ended December 31, 2025 are considered to be derived from "qualified interest income," as defined in Section 871(k)(1)(E) of the Code.

Investment objective, principal investment strategies, and principal risks (unaudited)

Investment Objective

The fund's investment objective is to generate current income.

Principal Investment Strategies

Under normal market conditions, the fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in senior loans. Senior loans include first and second lien term loans, delayed draw term loans, and revolving credit facilities. The fund may also make investments and acquire securities in connection with senior loans, including equity co-investments. Equity co-investments in which the fund may invest are typically small investments in a direct or indirect parent company of the borrower. Senior loans do not include commercial mortgage loans (including subordinated real estate mezzanine financing). The fund will only invest in loans and commitments that are determined to be below investment-grade. The fund's investment policies are based on credit quality at the time of purchase. Credit quality is determined by the Advisor. The fund may invest in loans with a maturity of up to nine years from the closing date of the loan. The Advisor typically expects to employ a buy-and-hold strategy. The fund may invest in loans either by transacting directly at the initial funding date or acquiring loans in secondary market transactions.

The fund may invest in loans secured by substantially all of the assets of the borrower and the other loan parties (subject to customary exceptions), including a pledge of the equity of the borrower and its subsidiaries. While real property is not a primary source of collateral, occasionally mortgages are part of the collateral package if the borrower owns particularly valuable real property. The fund may also invest in subordinated debt obligations to the extent permitted by the fund's investment restrictions.

The Advisor undertakes a comprehensive due diligence process, which includes a credit review and internal loan rating process as well as review of loan terms and collateral. The Advisor does not intend to cause the fund to borrow money or leverage its investments for the purpose of funding investments, other than in instances of short-term liquidity needs, and paying fund expenses.

The fund's investments may also include original-issue-discount instruments and contractual "payment-in-kind," or PIK, interest arrangements.

Principal Risks

An investment in the fund is subject to investment and market risks, including the possible loss of the entire principal invested.

The fund's main risks are listed below in alphabetical order, not in order of importance.

Changing distribution level & return of capital risk. There is no guarantee prior distribution levels will be maintained, and distributions may include a substantial tax return of capital. A return of capital is the return of all or a portion of a shareholder's investment in the fund.

Credit and counterparty risk. The issuer or guarantor of a fixed-income security may not make timely payments or otherwise honor its obligations. A downgrade or default affecting any of the fund's securities could affect the fund's performance.

Delayed funding loans and revolving credit facilities risk. Delayed funding loans and revolving credit facilities may have the effect of requiring the fund to increase its investment in a company at a time when it might not be desirable to do so (including at a time when the company's financial condition makes it unlikely that such amounts will be repaid). Delayed funding loans and revolving credit facilities are subject to credit, interest rate and liquidity risk and the risks of being a lender.

37

John Hancock GA Senior Loan Trust

Investment objective, principal investment strategies, and principal risks (unaudited)

Economic and market events risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Financial Institutions could suffer losses as interest rates rise or economic conditions deteriorate.

Fixed-income securities risk. A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payment or repay all or any of the principal borrowed.

Changes in a security's credit quality may adversely affect fund performance. Additionally, the value of inflation-indexed securities is subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). Generally, when real interest rates rise, the value of inflation-indexed securities will fall and the fund's value may decline as a result of this exposure to these securities.

Illiquid and restricted securities risk. Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.

Liquidity risk. The extent (if at all) to which a security may be sold without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal repurchase requests. Widespread selling of fixed-income securities during periods of reduced demand may adversely impact the price or salability of such securities.

Loan participations risk. Participations and assignments involve special types of risks, including credit risk, interest rate risk, liquidity risk, and the risks of being a lender. Investments in loan participations and assignments present the possibility that a fund could be held liable as a co-lender under emerging legal theories of lender liability. If a fund purchases a participation, it may only be able to enforce its rights through the lender and may assume the credit risk of the lender in addition to the borrower.

Lower-rated and high-yield fixed-income securities risk. Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.

Operational and cybersecurity risk. Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.

Senior loans risk. Senior loans may be comparatively less liquid relative to markets for other more liquid fixed income securities. Restrictions on transfers in loan agreements, a lack of publicly-available information, irregular trading activity and wide bid/ask spreads among other factors, may, in certain circumstances, make senior loans difficult to value accurately or sell at an advantageous time or price than other types of securities or instruments. Senior loans may have extended trade settlement periods which may result in cash not being immediately available. If an issuer of a senior loan prepays or redeems the loan prior to maturity, the fund may have to reinvest the proceeds in other senior loans or similar instruments that may pay lower interest rates. Senior loans in which the fund invests may or may not be collateralized, although the loans may not be fully collateralized and the collateral may be unavailable or insufficient to meet the obligations of the borrower. The fund may have limited rights to exercise remedies against such collateral or a borrower, and loan agreements may impose certain procedures that delay receipt of the proceeds of collateral or require the fund to act collectively with other creditors to exercise its rights with respect to a senior loan.

38

John Hancock GA Senior Loan Trust

Investment objective, principal investment strategies, and principal risks (unaudited)

Subordinated liens on collateral risk. Certain debt investments that the fund may make will be secured on a second priority basis by the same collateral securing senior secured debt of such companies. The first priority liens on the collateral will secure the fund's obligations under any outstanding senior debt and may secure certain other future debt that may be permitted to be incurred by the fund under the agreements governing the debt. The holders of obligations secured by the first priority liens on the collateral will generally control the liquidation of and be entitled to receive proceeds from any realization of the collateral to repay their obligations in full before the fund is so entitled. There can be no assurance that the proceeds, if any, from the sale or sales of all of the collateral would be sufficient to satisfy the debt obligations secured by the second priority liens after payment in full of all obligations secured by the first priority liens on the collateral.

Board considerations (unaudited)

EVALUATION OF ADVISORY AGREEMENT BY THE BOARD OF TRUSTEES

This section describes the evaluation by the Board of Trustees (the Board) of John Hancock Senior Loan Trust (the fund) of the Advisory Agreement between the fund and Manulife Investment Management Private Markets (US) LLC (the Advisor) (the Advisory Agreement). The Advisory Agreement was re-approved for an annual period at an in-person meeting on October 22, 2025. The Trustees who are not "interested persons" of the Trust as defined by the Investment Company Act of 1940, as amended (the 1940 Act) (the Independent Trustees) also met separately with counsel to the Independent Trustees to evaluate and discuss the information presented.

Continuation of Advisory Agreement

At an in-person meeting held on October 22, 2025, the Board, including all of the Independent Trustees, re-approved for an annual period the continuation of the Advisory Agreement. In considering the Advisory Agreement, the Board received in advance of the meeting a variety of materials relating to the fund and the Advisor, including (but not limited to), to the extent available, comparative performance information, including performance information for an applicable benchmark index, comparable information regarding industry peer investment companies as determined by an independent third party (Industry Peers), comparable funds and accounts managed by the Advisor (Adviser Comparable Funds), if any, and aggregate performance information for commercial real estate whole loan providers. With respect to expenses, the Board also received comparable fee and expense information for Industry Peers and Advisor Comparable Funds, if any, The Board also received information regarding the Advisor's revenues and costs of providing services to the fund and any compensation paid to affiliates of the Advisor, and other information provided by the Advisor regarding the nature, extent, and quality of services provided by the Advisor under the Advisory Agreement. The information received and considered by the Board in connection with the October meeting was both written and oral. The Board also considered the nature, quality, and extent of the non-advisory services, if any, provided to the fund by the Advisor's affiliates. Throughout the process, the Board asked questions of and was afforded the opportunity to request additional information from management. The Board was assisted by counsel for the fund and the Independent Trustees were also separately assisted by independent legal counsel throughout the process. The Independent Trustees also received a memorandum from their independent legal counsel discussing the legal standards for their consideration of the proposed continuation of the Advisory Agreement and discussed the proposed continuation of the Advisory Agreement in private sessions with their independent legal counsel at which no representatives of management were present.

In approving the continuation of the Advisory Agreement, the Board, including the Independent Trustees, considered a variety of factors, including those discussed below. The Board did not treat any single factor as determinative, and each Trustee may have attributed different weights to different factors. The Board noted that, at the meeting when the renewal of the Advisory Agreement is considered, particular focus is given to information the comparability of fund performance and fees and expenses to Industry Peers and Adviser Comparable Funds, if any, profitability and economies of scale. However, the Board noted that the evaluation process with respect to the Advisor is an ongoing one. In this regard, the Board also took into account discussions with management and information provided to the Board at prior meetings with respect to the services provided by the Advisor to the fund, including quarterly performance reports prepared by management containing reviews of investment results and prior presentations with respect to the fund.

Nature, extent and quality of services. Among the information received by the Board from the Advisor relating to the nature, extent and quality of services provided to the fund, the Board reviewed information provided by the Advisor relating to its operations and personnel, descriptions of its organizational and management structure, and information regarding the Advisor's compliance and regulatory history, including its Form ADV. The Board also noted that on a regular basis it receives and reviews information from the Trust's Chief Compliance Officer (CCO) regarding the fund's compliance policies and procedures

established pursuant to Rule 38a-1 under the 1940 Act. The Board observed that the scope of services provided by the Advisor, and of the undertakings required of the Advisor in connection with those services, including maintaining and monitoring its own and the fund's compliance programs, risk management and other programs, and cybersecurity programs, had expanded over time as a result of regulatory, market and other developments. The Board considered that the Advisor is responsible for the management of the day-to-day operations of the fund, and for monitoring and reviewing the activities of third-party service providers. The Board also considered the significant risks assumed by the Advisor in connection with the services provided to the fund including investment, operational, enterprise, regulatory and compliance risks.

In considering the nature, extent, and quality of the services provided by the Advisor, the Trustees also took into account their knowledge of the Advisor's management and the quality of the performance of the Advisor's duties, through Board meetings, discussions and reports during the preceding year and through each Trustee's experience as a Trustee of the Trust and of the other trusts in the John Hancock group of funds complex (the John Hancock Fund Complex).

In the course of their deliberations regarding the Advisory Agreement, the Board considered, among other things:

(a)the skills and competency with which the Advisor has in the past managed the Trust's affairs;

(b)the background, qualifications, and skills of the Advisor's personnel;

(c)the Advisor's compliance policies and procedures and its responsiveness to regulatory changes and fund industry developments;

(d)the Advisor's administrative capabilities, including its ability to supervise the other service providers for the fund;

(e)the financial condition of the Advisor and whether it has the financial wherewithal to continue to provide a high level and quality of services to the fund;

(f)the Advisor's initiatives intended to improve various aspects of the fund's operations; and

(g)the Advisor's reputation and experience in serving as an investment advisor to the Trust.

The Board concluded that the Advisor may reasonably be expected to continue to provide a high quality of services under the Advisory Agreement with respect to the fund.

Investment performance. In considering the fund's performance, the Board noted that it reviews at its regularly scheduled meetings information about the fund's performance results. In connection with the consideration of the Advisory Agreement, the Board:

(a)reviewed information prepared by management regarding the fund's performance;

(b)considered the comparative performance of an applicable benchmark index;

(c)considered the performance of lndustry Peers and Adviser Comparable Funds, if any; and

(d)took into account the Advisor's analysis of the fund's performance and any plans and recommendations regarding the fund.

The Board noted that while it found the Industry Peer data useful it recognized its limitations, including in particular that the data may vary depending on the end date selected and the results of the performance comparisons may vary depending on the strategies, including the use of leverage, and the fund structures of the peers presented. In this regard, the Board considered that management represented that it believes there are no investment companies that are a match to the fund. The Board noted that the fund outperformed its peer group median for the year-to-date, one-year, and three-year periods ended June 30,

41

John Hancock GA Senior Loan Trust

Board considerations (unaudited)

2025, and underperformed its peer group median for the quarter-to-date period ended June 30, 2025. The Board noted that the Fund outperformed its benchmark index for the year-to-date, one-year and three-year periods ended June 30, 2025, but underperformed for the quarter-to-date period ended June 30, 2025.

The Board took into account management's discussion of the fund's performance, including the favorable performance relative to its benchmark index for the year-to-date, one-year and three-year periods and relative to its peer group median for the year-to-date, one-year and three-year periods. The Board also took into account management's discussion of the factors that contributed to the fund's underperformance relative to its benchmark and peer group median for the quarter-to-date period.

Fees and Expenses. The Board reviewed comparative information regarding the fund's fees and expenses, including, among other data, the fund's management fees and net total expenses as compared to other comparable investment companies. The Board considered that the management fees were higher than the median advisory fees, and the net total expenses were lower than the median advisory fees across the universe of closed-end, interval funds presented and with respect to categories of closed-end interval funds that most closely align with the fund's investment strategy. The Board noted that the peer group was imperfect given the unique investment strategy and structure of the Fund. The Board took into account management's discussion of the fund's expenses. The Board reviewed information provided by the Advisor concerning investment advisory fees charged to other clients having similar investment mandates, noting that none of the comparable mandates were an exact match to the Fund. The Board considered any difference between the Advisor's services to the fund and the services it provides to Adviser Comparable Funds.

The Board concluded that the advisory fees paid by the fund are reasonable in light of the nature, extent and quality of the services provided to the fund under the Advisory Agreement.

Profitability/Fall Out Benefits. In considering the costs of the services provided and the profits realized by the Advisor and its affiliates from the Advisor's relationship with the fund, the Board:

(a)reviewed financial information of the Advisor;

(b)considered that the Advisor will also provide administrative services to the fund on a cost basis pursuant to a services agreement;

(c)noted that affiliates of the Advisor will provide placement agency services to the fund;

(d)noted that the Advisor will derive reputational and other indirect benefits from providing advisory services to the fund;

(e)considered that the Advisor should be entitled to earn a reasonable level of profits in exchange for the level of services it will provide to the fund and the risks that it assumes as Advisor, including entrepreneurial, operational, reputational, and regulatory risk; and

(f)reviewed and considered information presented by the Advisor regarding the net profitability to the Advisor and its affiliates with respect to the fund.

Economies of Scale. In considering the extent to which the fund realizes any economies of scale and whether the fee level reflects these economies of scale for the benefit of the fund's shareholders, the Board took into account management's discussions of the current advisory fee structure, and, as noted above, the services the Advisor provides in performing its functions under the Advisory Agreement. In considering the extent to which economies of scale would be realized if the fund grows and whether the fee level reflects these economies of scale, the Board: (a) reviewed the fund's advisory fee structure and took into account management's discussion of the fund's advisory fee structure; and (b) also considered the potential effect of the fund's future growth in size on its performance and fees.

The aggregate fees billed for professional services rendered by the principal accountant for tax compliance, tax advice and tax planning ("tax fees") amounted to $15,750 and $15,750 for the fiscal years ended December 31, 2025 and December 31, 2024, respectively.

(e)(1) Audit Committee Pre-Approval Policies and Procedures

The registrant's Audit Committee must pre-approve all audit and non-audit services provided by the independent registered public accounting firm (the "Auditor") relating to the operations or financial reporting of the fund. Prior to the commencement of any audit or non-audit services to a fund, the Audit Committee reviews the services to determine whether they are appropriate and permissible under applicable law.

The registrant's Audit Committee has adopted policies and procedures to, among other purposes, provide a framework for the Committee's consideration of audit-related and non-audit services by the Auditor. The policies and procedures require that any audit- related and non-audit service provided by the Auditor and any non-audit service provided by the Auditor to a fund service provider that relates directly to the operations and financial reporting of a fund are subject to approval by the Audit Committee before such service is provided. Audit-related services provided by the Auditor that are expected to exceed $25,000 per instance/per fund are subject to specific pre-approval by the Audit Committee. Tax services provided by the Auditor that are expected to exceed $30,000 per instance/per fund are subject to specific pre-approval by the Audit Committee.

All audit services, as well as the audit-related and non-audit services that are expected to exceed the amounts stated above, must be approved in advance of provision of the service by formal resolution of the Audit Committee. At the regularly scheduled Audit Committee meetings, the Committee reviews a report summarizing the services, including fees, provided by the Auditor.

(e)(2) Services approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

Audit-Related Fees, Tax Fees and All Other Fees

There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception under Rule 2-01 of Regulation S-X.

(f)According to the registrant's principal accountant for the fiscal year ended December 31, 2025, the percentage of hours spent on the audit of the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons who were not full-time, permanent employees of principal accountant was less than 50%.

(g)The aggregate non-audit fees billed by the registrant's principal accountant for non-audit services rendered to the registrant and rendered to the registrant's control affiliates were $3,668,184 for the fiscal year ended December 31, 2025 and $2,789,791 for the fiscal year ended December 31, 2024.

(h)The audit committee of the registrant has considered the non-audit services provided by the registrant's principal accountant to the control affiliates and has determined that the services that were not pre-approved are compatible with maintaining the principal accountant's independence.

Conflicts of Interest. The portfolio managers serve in a dual capacity as an officer of the Adviser and an employee and officer of one or more John Hancock affiliated companies (John Hancock). In these roles they provide investment advice and/or investment management-related services to John Hancock as well the Adviser's advisory client accounts. As such, there may be an incentive to favor one account over another, resulting in conflicts of interest. For instance, the Adviser or John Hancock may, for example,

directly or indirectly, receive fees from an account that are higher than the fee (or other economic benefit) it receives from the Fund. In those instances, the portfolio managers may have an incentive to not favor the Fund over another account. The Adviser has or will adopt, as relevant, trade allocation and other policies and procedures that it believes are reasonably designed to address any potential conflicts of interest.

Compensation of Portfolio Managers. At the present time, the portfolio managers are paid by John Hancock a fixed annual salary as well as an employment compensation bonus that is currently based (in part) on the investment performance of certain accounts of John Hancock and its affiliates. This performance is independent of the Adviser's account-level performance on behalf of its clients. However, since commercial mortgage loans are invested as part of a co-investment program, the performance of the underlying investments of the John Hancock GA Senior Loan Trust do indirectly contribute to overall compensation of the portfolio management team.

Share Ownership by Portfolio Managers. The following table indicates as of December 31, 2025, the dollar range of fund shares and shares of similarly managed accounts beneficially owned by the portfolio managers in the Fund. For purposes of this table, "similarly managed accounts" include all accounts that are managed (i) by the same portfolio managers that are jointly and primarily responsible for the day-to- day management of the Fund; and (ii) with an investment style, objective, policies and strategies substantially similar to those that are used to manage the Fund.
