INVESTMENT OBJECTIVE

The fund seeks to generate a high level of current income consistent with prudent investment risk.
AVERAGE ANNUAL TOTAL RETURNS AS OF 4/30/2026 (%)

The Bloomberg U.S. Aggregate Bond Index tracks the performance of U.S. investment-grade bonds in government, asset-backed, and corporate debt markets. The fund changed its index from the Bloomberg U.S. Government/Credit Index to the Bloomberg U.S. Aggregate Bond Index to align with index changes across the fund complex.
It is not possible to invest directly in an index. Index figures do not reflect expenses, which would result in lower returns.
The performance data contained within this material represents past performance, which does not guarantee future results.
Investment returns and principal value will fluctuate and a shareholder may sustain losses. Further, the fund’s performance at net asset value (NAV) is different from the fund’s performance at closing market price because the closing market price is subject to the dynamics of secondary market trading. Market risk may increase when shares are purchased at a premium to NAV or sold at a discount to NAV. Current month-end performance may be higher or lower than the performance cited. The fund’s most recent performance can be found at jhinvestments.com or by calling 800-852-0218.

Notes to financial statements (unaudited)
Note 1Organization
John Hancock Income Securities Trust (the fund) is a closed-end management investment company organized as a Massachusetts business trust and registered under the Investment Company Act of 1940, as amended (the 1940 Act).
Note 2Significant accounting policies
The 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 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 of US GAAP.
Events or transactions occurring after the end of the fiscal period through the date that the 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 stated at value as of the scheduled close of regular trading on the New York Stock Exchange (NYSE), normally at 4:00 P.M., Eastern Time. In case of emergency or other disruption resulting in the NYSE not opening for trading or the NYSE closing at a time other than the regularly scheduled close, the net asset value (NAV) may be determined as of the regularly scheduled close of the NYSE pursuant to the Valuation Policies and Procedures of the Advisor, John Hancock Investment Management LLC, the fund’s valuation designee.
In order to value the securities, the fund uses the following valuation techniques: Debt obligations are typically valued based on 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. Equity securities, including exchange-traded or closed-end funds, are typically valued at the last sale price or official closing price on the exchange or principal market where the security trades. In the event there were no sales during the day or closing prices are not available, the securities are valued using the last available bid price. Investments by the fund in open-end mutual funds, including John Hancock Collateral Trust (JHCT), are valued at their respective NAVs each business day.
In certain instances, the Pricing Committee of the Advisor 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.
Other portfolio securities and assets, for which reliable market quotations are not readily available, are valued at fair value as determined in good faith by the Pricing Committee following procedures established by the Advisor and adopted by the Board of Trustees. The frequency with which these fair valuation procedures are used cannot be predicted and fair value of securities may differ significantly from the value that would have been used had a ready market for such securities existed.
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, including registered investment companies. 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 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

The fund holds liabilities for which the fair value approximates the carrying amount for financial statement purposes. As of April 30, 2026, the liability for the fund’s Liquidity agreement on the Statement of assets and liabilities is categorized as Level 2 within the disclosure hierarchy.
When-issued/delayed-delivery securities. The fund may purchase or sell securities on a when-issued or delayed-delivery basis, or in a “To Be Announced” (TBA) or “forward commitment” transaction, with delivery or payment to occur at a later date beyond the normal settlement period. TBA securities resulting from these transactions are included in the portfolio or in a schedule to the portfolio (Sale Commitments Outstanding). At the time a fund enters into a commitment to purchase or sell a security, the transaction is recorded and the value of the security is reflected in its NAV. The price of such security and the date that the security will be delivered and paid for are fixed at the time the transaction is negotiated. The value of the security may vary with market fluctuations. No interest accrues on debt securities until settlement takes place. At the time that the fund enters into this type of transaction, the fund is required to have sufficient cash and/or liquid securities to cover its commitments.
Certain risks may arise upon entering into when-issued or delayed-delivery securities transactions, including the potential inability of counterparties to meet the terms of their contracts, and the issuer’s failure to issue the securities due to political, economic or other factors. Additionally, losses may arise due to changes in the value of the securities purchased or sold prior to settlement date.
Mortgage and asset-backed securities. The fund may invest in mortgage-related securities, such as mortgage-backed securities, and other asset-backed securities, which are debt obligations that represent interests in pools of mortgages or other income-bearing assets, such as consumer loans or receivables. Such securities often involve risks that are different from the risks associated with investing in other types of debt securities.
41 JOHN HANCOCK Income Securities Trust | SEMIANNUAL REPORT  

Table of Contents
Mortgage-backed and other asset-backed securities are subject to changes in the payment patterns of borrowers of the underlying debt. When interest rates fall, borrowers are more likely to refinance or prepay their debt before its stated maturity. This may result in the fund having to reinvest the proceeds in lower yielding securities, effectively reducing the fund’s income. Conversely, if interest rates rise and borrowers repay their debt more slowly than expected, the time in which the mortgage-backed and other asset-backed securities are paid off could be extended, reducing the fund’s cash available for reinvestment in higher yielding securities.  The timely payment of principal and interest of certain mortgage-related securities is guaranteed with the full faith and credit of the U.S. Government. Pools created and guaranteed by non-governmental issuers, including government-sponsored corporations (e.g., FNMA), may be supported by various forms of insurance or guarantees, but there can be no assurance that private insurers or guarantors can meet their obligations under the insurance policies or guarantee arrangements. The fund is also subject to risks associated with securities with contractual cash flows including asset-backed and mortgage related securities such as collateralized mortgage obligations, mortgage pass-through securities and commercial mortgage-backed securities. The value, liquidity and related income of these securities are sensitive to changes in economic conditions, including real estate value, pre-payments, delinquencies and/or defaults, and may be adversely affected by shifts in the market’s perception of the issuers and changes in interest rates.
Security transactions and related investment income. Investment security transactions are accounted for on a trade date plus one basis for daily 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. Dividend income is recorded on ex-date, except for dividends of certain foreign securities where the dividend may not be known until after the ex-date. In those cases, dividend income, net of withholding taxes, is recorded when the fund becomes aware of the dividends. Non-cash dividends, if any, are recorded at the fair market value of the securities received. Distributions received on securities that represent a tax return of capital and/or capital gain, if any, are recorded as a reduction of cost of investments and/or as a realized gain, if amounts are estimable. 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.
Expenses. Within the John Hancock group of funds complex, expenses that are directly attributable to an individual fund are allocated to such fund. Expenses that are not readily attributable to a specific fund are allocated among all funds in an equitable manner, taking into consideration, among other things, the nature and type of expense and the fund’s relative net assets. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.
Statement of cash flows. A Statement of cash flows is presented when a fund has a significant amount of borrowing during the period, based on the average total borrowing in relation to total assets, or 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 Statement of cash flows. The cash amount shown in the Statement of cash flows is the amount included in the fund’s Statement of assets and liabilities and represents the cash on hand at the fund’s custodian and does not include any short-term investments or collateral on derivative contracts, if any.
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.
  SEMIANNUAL REPORT | JOHN HANCOCK Income Securities Trust 42

Table of Contents
For federal income tax purposes, as of October 31, 2025, the fund has a short-term capital loss carryforward of $6,978,270 and a long-term capital loss carryforward of $22,466,513 available to offset future net realized capital gains. These carryforwards do not expire.
As of October 31, 2025, the fund had no uncertain tax positions that would require 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 quarterly. Capital gain distributions, if any, are typically distributed annually.
Such distributions, 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. The final determination of tax characteristics of the fund’s distribution will occur at the end of the year and will subsequently be reported to shareholders.
Capital accounts within the 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 amortization and accretion on debt securities and derivative transactions.
Note 3Guarantees 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.
Note 4Fees and transactions with affiliates
John Hancock Investment Management LLC (the Advisor) serves as investment advisor for the fund. The Advisor is an indirect, principally owned subsidiary of John Hancock Life Insurance Company (U.S.A.), which in turn is a subsidiary of Manulife Financial Corporation (MFC).
Management fee. The fund has an investment management agreement with the Advisor under which the fund pays a daily management fee to the Advisor equivalent on an annual basis to the sum of (a) 0.650% of the first $150 million of the fund’s average daily managed assets (net assets plus borrowings under the Liquidity Agreement (LA) (see Note 8), (b) 0.375% of the next $50 million of the fund’s average daily managed assets, (c) 0.350% of the next $100 million of the fund’s average daily managed assets and (d) 0.300% of the fund’s average daily managed assets in excess of $300 million. The Advisor has a subadvisory agreement with Manulife Investment Management (US) LLC, an indirectly owned subsidiary of MFC and an affiliate of the Advisor. The fund is not responsible for payment of the subadvisory fees.
The Advisor has contractually agreed to waive a portion of its management fee and/or reimburse expenses for certain funds of the John Hancock group of funds complex, including the fund (the participating portfolios). This waiver is based upon aggregate net assets of all the participating portfolios. With respect to participating portfolios that pay advisory fees based on managed assets, "aggregate net assets" includes managed assets of the participating porfolios. The amount of the reimbursement is calculated daily and allocated among all the participating portfolios in proportion to the daily net assets of each fund. During the six months ended April 30, 2026, this waiver amounted to 0.01% of the fund’s average daily managed assets, on an annualized basis. This agreement expires on July 31, 2027, unless renewed by mutual agreement of the fund and the Advisor based upon a determination that this is appropriate under the circumstances at that time.
43 JOHN HANCOCK Income Securities Trust | SEMIANNUAL REPORT  

Table of Contents
The expense reductions described above amounted to $11,216 for the six months ended April 30, 2026.
Expenses waived or reimbursed in the current fiscal period are not subject to recapture in future fiscal periods.
The investment management fees, including the impact of the waivers and reimbursements as described above, incurred for the six months ended April 30, 2026, were equivalent to a net annual effective rate of 0.54% of the fund’s average daily managed assets.
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 six months ended April 30, 2026, amounted to an annual rate of 0.01% of the fund’s average daily managed net assets.
Trustee expenses. The fund compensates each Trustee who is not an employee of the Advisor or its affiliates. These Trustees receive from the fund and the other John Hancock closed-end funds an annual retainer. In addition, Trustee out-of-pocket expenses are allocated to each fund based on its net assets relative to other funds within the John Hancock group of funds complex.
Note 5Fund share transactions
On March 12, 2015, the Board of Trustees approved a share repurchase plan, which is subsequently reviewed by the Board of Trustees each year in December. Under the current share repurchase plan, the fund may purchase in the open market, between January 1, 2026 and December 31, 2026, up to 10% of its outstanding common shares as of December 31, 2025. The share repurchase plan will remain in effect between January 1, 2026 and December 31, 2026.
During the six months ended April 30, 2026 and the year ended October 31, 2025, the fund had no activities under the repurchase program. Shares repurchased and corresponding dollar amounts, if any, are included on the Statements of changes in net assets. The anti-dilutive impacts of these share repurchases, if any, are included on the Financial highlights.
Note 6Leverage risk
The fund utilizes the LA to increase its assets available for investment. When the fund leverages its assets, shareholders bear the expenses associated with the LA and have potential to benefit or be disadvantaged from the use of leverage. The Advisor’s fee is also increased in dollar terms from the use of leverage. Consequently, the fund and the Advisor may have differing interests in determining whether to leverage the fund’s assets. Leverage creates risks that may adversely affect the return for the holders of shares, including:
the likelihood of greater volatility of NAV and market price of shares;
fluctuations in the interest rate paid for the use of the LA;
increased operating costs, which may reduce the fund’s total return;
the potential for a decline in the value of an investment acquired through leverage, while the fund’s obligations under such leverage remains fixed; and
the fund is more likely to have to sell securities in a volatile market in order to meet asset coverage or other debt compliance requirements.
To the extent the income or capital appreciation derived from securities purchased with funds received from leverage exceeds the cost of leverage, the fund’s return will be greater than if leverage had not been used; conversely, returns would be lower if the cost of the leverage exceeds the income or capital appreciation derived. The use of securities lending to obtain leverage in the fund’s investments may subject the fund to greater risk of loss than would reinvestment of collateral in short term highly rated investments.
In addition to the risks created by the fund’s use of leverage, the fund is subject to the risk that it would be unable
  SEMIANNUAL REPORT | JOHN HANCOCK Income Securities Trust 44

Table of Contents
to timely, or at all, obtain replacement financing if the LA is terminated. Were this to happen, the fund would be required to de-leverage, selling securities at a potentially inopportune time and incurring tax consequences. Further, the fund’s ability to generate income from the use of leverage would be adversely affected.
Note 7Liquidity Agreement
The fund has entered into a LA with State Street Bank and Trust Company (SSB) that allows it to borrow or otherwise access up to $91.3 million (maximum facility amount) through a line of credit, securities lending and reverse repurchase agreements. The amounts outstanding at April 30, 2026 are shown in the Statement of assets and liabilities as the Liquidity agreement.
The fund pledges its assets as collateral to secure obligations under the LA. The fund retains the risks and rewards of the ownership of assets pledged to secure obligations under the LA and makes these assets available for securities lending and reverse repurchase transactions with SSB acting as the fund’s authorized agent for these transactions. All transactions initiated through SSB are required to be secured with cash collateral received from the securities borrower (the Borrower) or cash is received from the reverse repurchase agreement (Reverse Repo) counterparties. Securities lending transactions will be secured with cash collateral in amounts at least equal to 100% of the market value of the securities utilized in these transactions. Cash received by SSB from securities lending or Reverse Repo transactions is credited against the amounts borrowed under the line of credit. As of April 30, 2026, the LA balance of $91,300,000 was comprised of $84,244,042 from the line of credit and $7,055,958 cash received by SSB from securities lending or Reverse Repo transactions.
Upon return of securities by the Borrower or Reverse Repo counterparty, SSB will return the cash collateral to the Borrower or proceeds from the Reverse Repo, as applicable, which will eliminate the credit against the line of credit and will cause the drawdowns under the line of credit to increase by the amounts returned. Income earned on the loaned securities is retained by SSB, and any interest due on the reverse repurchase agreements is paid by SSB.
SSB has indemnified the fund for certain losses that may arise if the Borrower or a Reverse Repo Counterparty fails to return securities when due. With respect to securities lending transactions, upon a default of the securities borrower, SSB uses the collateral received from the Borrower to purchase replacement securities of the same issue, type, class and series. If the value of the collateral is less than the purchase cost of replacement securities, SSB is responsible for satisfying the shortfall but only to the extent that the shortfall is not due to any of the fund’s losses on the reinvested cash collateral. Although the risk of the loss of the securities is mitigated by receiving collateral from the Borrower or proceeds from the Reverse Repo counterparty and through SSB indemnification, the fund could experience a delay in recovering securities or could experience a lower than expected return if the Borrower or Reverse Repo counterparty fails to return the securities on a timely basis.
Interest charged is at the rate of overnight bank funding rate (OBFR) plus 0.700% and is payable monthly on the aggregate balance of the drawdowns outstanding under the LA. As of April 30, 2026, the fund had an aggregate balance of $91,300,000 at an interest rate of 4.34%, which is reflected in the Liquidity agreement on the Statement of assets and liabilities. During the six months ended April 30, 2026, the average balance of the LA and the effective average annual interest rate were $91,300,000 and 4.45%, respectively.
The fund may terminate the LA with 60 days’ notice. If certain asset coverage and collateral requirements, or other covenants are not met, the LA could be deemed in default and result in termination. Absent a default or facility termination event, SSB is required to provide the fund with 360 days’ notice prior to terminating the LA.
Note 8Purchase and sale of securities
Purchases and sales of securities, other than short-term investments and U.S. Treasury obligations, amounted to $39,702,156 and $34,848,737, respectively, for the six months ended April 30, 2026. Purchases and sales of U.S. Treasury obligations aggregated $10,503,538 and $12,495,856, respectively, for the six months ended April 30, 2026.

Note 9Industry or sector risk
The fund may invest a large percentage of its assets in one or more particular industries or sectors of the economy. If a large percentage of the fund’s assets are economically tied to a single or small number of industries or sectors of the economy, the fund will be less diversified than a more broadly diversified fund, and it may cause the fund to underperform if that industry or sector underperforms. In addition, focusing on a particular industry or sector may make the fund’s NAV more volatile. Further, a fund that invests in particular industries or sectors is particularly susceptible to the impact of market, economic, regulatory and other factors affecting those industries or sectors.
Note 10Investment in affiliated underlying funds
The fund may invest in affiliated underlying funds that are managed by the Advisor and its affiliates. Information regarding the fund’s fiscal year to date purchases and sales of the affiliated underlying funds as well as income and capital gains earned by the fund, if any, is as follows:

Note 11Segment 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 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 Statement of operations, which includes “Increase (decrease) in net assets from operations”, Statements of changes in net assets, which includes “Increase (decrease) in net assets from fund share transactions”, and Financial highlights, which includes total return and income and expense ratios.

Investment objective, principal investment strategies, and principal risks

Unaudited
Investment Objective
The fund’s investment objective is to generate a high level of current income consistent with prudent investment risk.
Principal Investment Strategies
Under normal circumstances the Fund will invest at least 80% of its net assets (plus borrowings for investment purposes) in income securities. This is a non-fundamental policy and may be changed by the Board of Trustees of the fund provided that shareholders are provided with at least 60 days prior written notice of any change as required by the rules under the 1940 Act. Not more than 20% of the Fund’s total assets will consist of such preferred securities and common stocks believed by the Fund to provide a sufficiently high yield to attain the Fund’s investment objective. Income securities will consist of the following: (i) marketable corporate debt securities, (ii) governmental obligations and (iii) cash and commercial paper.
The Fund will invest at least 75% of its net assets (plus borrowings for investment purposes) in debt securities that are rated, at the time of acquisition, investment grade (i.e., at least “Baa” by Moody’s Investors Service, Inc. (Moody’s) or “BBB” by Standard & Poor’s Global Ratings Inc. (S&P)), or in unrated securities determined by the Fund’s investment advisor or subadvisor to be of comparable credit quality. The Fund can invest up to 25% of its net assets (plus borrowings for investment purposes) in debt securities that are rated, at the time of acquisition, below investment grade (junk bonds) (i.e., rated “Ba” or lower by Moody’s or “BB” or lower by S&P), or in unrated securities determined by the Fund’s advisor or subadvisor to be of comparable quality.
Although the Fund will focus on securities of U.S. issuers, the Fund may invest in securities of corporate and governmental issuers located outside the United States that are payable in U.S. dollars, including emerging markets. The Fund may also invest in mortgage-backed and asset-backed securities, including collateralized mortgage obligations. In addition, the Fund may invest in repurchase agreements.
The Fund may also invest in derivatives such as swaps and reverse repurchase agreements. The Fund intends to use reverse repurchase agreements to obtain investment leverage either alone and/or in combination with other forms of investment leverage or for temporary purposes. The Fund utilizes a liquidity agreement to increase its assets available for investments, and may also seek to obtain additional income or portfolio leverage by making secured loans of its portfolio securities with a value of up to 33 1/3% of its total assets. The Fund may also invest up to 20% of its total assets in illiquid securities.
The manager may consider environmental, social, and/or governance (ESG) factors, alongside other relevant factors, as part of its investment process. ESG factors may include, but are not limited to, matters regarding board diversity, climate change policies, and supply chain and human rights policies. The ESG characteristics utilized in the fund’s investment process may change over time and one or more characteristics may not be relevant with respect to all issuers that are eligible fund investments. Because ESG factors are considered alongside other relevant factors, the manager may determine that an investment is appropriate notwithstanding its relative ESG characteristics.
Principal Risks
As is the case with all exchange-listed closed-end funds, shares of this fund may trade at a discount or a premium to the fund’s net asset value (NAV). 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.
47 JOHN HANCOCK INCOME SECURITIES TRUST | SEMIANNUAL REPORT  

Table of Contents
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, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund’s securities could affect the fund’s performance.
Economic and market events risk. Events in the U.S. and global financial markets, including actions taken by 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. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.
Emerging Markets risk. The risks of investing in foreign securities are magnified in emerging markets. Emerging-market countries may experience higher inflation, interest rates, and unemployment and greater social, economic, and political uncertainties than more developed countries.
Equity securities risk. The price of equity securities may decline due to changes in a company’s financial condition or overall market conditions.
ESG integration risk. The manager considers ESG factors that it deems relevant or additive, along with other material factors and analysis, when managing the fund. The manager may consider these ESG factors on all or a meaningful portion of the fund’s investments.  In certain situations, the extent to which these ESG factors may be applied according to the manager’s integrated investment process may not include U.S. Treasuries, government securities, or other asset classes. ESG factors may include, but are not limited to, matters regarding board diversity, climate change policies, and supply chain and human rights policies. Incorporating ESG criteria and making investment decisions based on certain ESG characteristics, as determined by the manager, carries the risk that the fund may perform differently, including underperforming funds that do not utilize ESG criteria or funds that utilize different ESG criteria. Integration of ESG factors into the fund’s investment process may result in a manager making different investments for the fund than for a fund with a similar investment universe and/or investment style that does not incorporate such considerations in its investment strategy or processes, and the fund’s investment performance may be affected. Because ESG factors are one of many considerations for the fund, the manager may nonetheless include companies with low ESG characteristics or exclude companies with high ESG characteristics in the fund’s investments.
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 qualify 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. 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.
Foreign securities risk. Less information may be publicly available regarding foreign issuers, including foreign government issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities.
Hedging, derivatives, and other strategic transactions risk. Hedging, derivatives, and other strategic transactions may increase a fund’s volatility and could produce disproportionate losses, potentially more than the fund’s principal investment. Risks of these transactions are different from and possibly greater than risks of
  SEMIANNUAL REPORT | JOHN HANCOCK INCOME SECURITIES TRUST 48

Table of Contents
investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Derivatives and other strategic transactions that the fund intends to utilize include: swaps and reverse repurchase agreements. Swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. An event of default or insolvency of the counterparty to a reverse repurchase agreement could result in delays or restrictions with respect to the fund’s ability to dispose of the underlying securities. In addition, a reverse repurchase agreement may be considered a form of leverage and may, therefore, increase fluctuations in the fund’s NAV.
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.
Leveraging risk. Issuing preferred shares or using derivatives may result in a leveraged portfolio. Leveraging long exposures increases a fund’s losses when the value of its investments declines. Some derivatives have the potential for unlimited loss, regardless of the size of the initial investment. The fund also utilizes a Liquidity Agreement to increase its assets available for investment. See “Note 7 —Leverage risk” above.
Liquidity risk. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Widespread selling of fixed-income securities during periods of reduced demand may adversely impact the price or salability of such securities.
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.
Mortgage-backed and asset-backed securities risk. Mortgage-backed and asset-backed securities are subject to different combinations of prepayment, extension, interest-rate, and other market risks. Factors that impact the value of these securities include interest rate changes, the reliability of available information, credit quality or enhancement, and market perception.
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.
Preferred and convertible securities risk. Preferred stock dividends are payable only if declared by the issuer’s board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock’s value can depend heavily upon the underlying common stock’s value.
U.S. Government agency obligations risk. U.S. government-sponsored entities such as Federal National Mortgage Association (Fannie Mae), Federal Home Loan Mortgage Corporation (Freddie Mac) and the Federal Home Loan Banks, although chartered or sponsored by Congress, are not funded by congressional appropriations and the debt securities that they issue are neither guaranteed nor issued by the U.S. government. Such debt securities are subject to the risk of default on the payment of interest and/or principal, similar to the debt securities of private issuers. The maximum potential liability of the issuers of some U.S. government obligations may greatly exceed their current resources, including any legal right to support from the U.S. government. Although the U.S. government has provided financial support to Fannie Mae and Freddie Mac in the past, there can be no assurance that it will support these or other government-sponsored entities in the future.
