A message to shareholders
Dear shareholders,
Bonds declined as yields rose to their highest levels in more than a decade during the 12 months ended October 31, 2022. The 12-month U.S. inflation rate peaked in June at a 40-year high of 9.1% before falling back, but it remained at elevated levels in the ensuing months. The U.S. Federal Reserve (Fed) continued its inflation-fighting campaign by raising short-term interest rates three times, boosting the federal funds rate target to its highest level in more than 14 years. While bond yields rose broadly for the period, short-term yields climbed the most in response to changing Fed policy.
In these uncertain times, your financial professional can assist with positioning your portfolio so that it’s sufficiently diversified to help meet your long-term objectives and to withstand the inevitable bouts of market volatility along the way.
On behalf of everyone at John Hancock Investment Management, I’d like to take this opportunity to welcome new shareholders and thank existing shareholders for the continued trust you’ve placed in us.
Sincerely,
Andrew G. Arnott
Global Head of Retail,
Manulife Investment Management
President and CEO,
John Hancock Investment Management
Head of Wealth and Asset Management,
United States and Europe

INVESTMENT OBJECTIVE

The fund seeks to generate a high level of current income consistent with prudent investment risk.
AVERAGE ANNUAL TOTAL RETURNS AS OF 10/31/2022 (%)

The Bloomberg U.S. Government/Credit Index tracks the performance of U.S. government bonds, U.S. corporate bonds, and Yankee bonds.
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.

2 JOHN HANCOCK INCOME SECURITIES TRUST  | ANNUAL REPORT  

PERFORMANCE HIGHLIGHTS OVER THE LAST TWELVE MONTHS

Rising inflation put downward pressure on U.S. bond market
The highest inflation rate in four decades led to a sharp rise in U.S. interest rates, which pushed bond prices sharply lower.
Sector performance was uniformly negative
Investment-grade corporate bonds posted the largest declines, weighed down by economic uncertainty, while asset-backed securities and other short-term sectors held up the best.
The fund underperformed its comparative index
The fund’s leverage exacerbated the declines in its fixed-income holdings, resulting in a return that trailed the performance of the Bloomberg U.S. Government/Credit Bond Index.

Management’s discussion of fund performance
How did the U.S. bond market perform during the 12 months ended October 31, 2022?
U.S. bonds experienced substantial declines as interest rates rose sharply. Inflation surged to its highest level in more than 40 years, driven by steep increases in food and energy prices. To rein in inflationary pressures, the U.S. Federal Reserve (Fed) raised short-term interest rates aggressively over the last six months of the period. The Fed’s actions pushed bond yields broadly higher, putting downward pressure on bond prices.
On a sector basis, investment-grade corporate bonds declined the most as investors grew increasingly concerned that the Fed rate hikes would lead to an economic downturn. Residential mortgage-backed securities also underperformed as mortgage rates soared, while shorter-term sectors such as asset-backed securities held up the best.
How did the fund perform?
The fund declined significantly on both a net asset value and market price basis, trailing the return of its comparative index. The fund uses leverage to increase its overall fixed-income exposure, which helps boost the income the fund produces for shareholders. However, it also amplifies investment returns, whether in a positive or negative direction, and in a period in which bonds were down meaningfully, the fund declined to a greater extent than the broader bond market.
Sector allocation also weighed on performance compared with the index. An underweight position in U.S. Treasury securities and an overweight position in agency mortgage-backed securities detracted. The fund’s largest sector weighting was in corporate bonds, where investment-grade and high-yield bonds constituted

more than half of the portfolio on average during the period. The fund’s corporate bond holdings also detracted from relative results.
On the positive side, the fund’s duration positioning (a measure of interest-rate sensitivity) aided relative performance. The fund’s duration of approximately 5 years was notably shorter than the index’s duration of approximately 7 years, which helped mitigate the negative impact of rising bond yields on the fund’s return.
How was the portfolio positioned at the end of the reporting period?
Corporate bonds remain a significant component of the portfolio as considerably higher yields should lead to attractive returns going forward; however, we’ve positioned the portfolio more defensively. Individual security selection will continue to be a key part of our investment approach, with an emphasis on risk-adjusted returns, which should help in navigating the softening economic landscape.
Can you tell us about an addition to the portfolio management team?
Effective March 31, 2022, Connor Minnaar, CFA, was added to the team.

Notes to financial statements
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 Advisor’s Valuation Policies and Procedures.
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
40 JOHN HANCOCK Income Securities Trust | ANNUAL REPORT  

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.

The fund holds liabilities for which the fair value approximates the carrying amount for financial statement purposes. As of October 31, 2022, 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 debt 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 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.
Term loans (Floating rate loans). The fund may invest in term loans, which are debt securities and are often rated below investment grade at the time of purchase. Term loans are generally subject to legal or contractual restrictions on resale and generally have longer settlement periods than conventional debt securities. Term loans involve special types of risk, including credit risk, interest-rate risk, counterparty risk, and risk associated with
  ANNUAL REPORT | JOHN HANCOCK Income Securities Trust 41

extended settlement. The liquidity of term loans, including the volume and frequency of secondary market trading in such loans, varies significantly over time and among individual loans. During periods of infrequent trading, valuing a term loan can be more difficult and buying and selling a term loan at an acceptable price can be more difficult and delayed, which could result in a loss.
The fund’s ability to receive payments of principal, interest and other amounts in connection with term loans will depend primarily on the financial condition of the borrower. The fund’s failure to receive scheduled payments on a term loan due to a default, bankruptcy or other reason would adversely affect the fund’s income and would likely reduce the value of its assets. Transactions in loan investments typically take a significant amount of time (i.e., seven days or longer) to settle. This could pose a liquidity risk to the fund. Because term loans may not be rated by independent credit rating agencies, a decision to invest in a particular loan could depend exclusively on the subadvisor’s credit analysis of the borrower and/or term loan agents. There is greater risk that the fund may have limited rights to enforce the terms of an underlying loan than for other types of debt instruments.
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. 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.
Foreign taxes. The fund may be subject to withholding tax on income, capital gains or repatriations imposed by certain countries, a portion of which may be recoverable. Foreign taxes are accrued based upon the fund’s understanding of the tax rules and rates that exist in the foreign markets in which it invests. Taxes are accrued
42 JOHN HANCOCK Income Securities Trust | ANNUAL REPORT  

based on gains realized by the fund as a result of certain foreign security sales. In certain circumstances, estimated taxes are accrued based on unrealized appreciation of such securities. Investment income is recorded net of foreign withholding taxes.
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.
For federal income tax purposes, as of October 31, 2022, the fund has a short-term capital loss carryforward of $4,818,144 and a long-term capital loss carryforward of $4,162,787 available to offset future net realized capital gains. These carryforwards do not expire.
As of October 31, 2022, 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.
The tax character of distributions for the years ended October 31, 2022 and 2021 was as follows:
  October 31, 2022 October 31, 2021
Ordinary income $8,926,367 $10,281,607
Long-term capital gains 1,789,658
Total $10,716,025 $10,281,607
As of October 31, 2022, the components of distributable earnings on a tax basis consisted of $789,194 of undistributed ordinary income.
Such distributions and distributable earnings, on a tax basis, 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.
  ANNUAL REPORT | JOHN HANCOCK Income Securities Trust 43

Capital accounts within the financial statements are adjusted for permanent book-tax differences. 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.
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 (see Note 7), (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. 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 year ended October 31, 2022, this waiver amounted to 0.01% of the fund’s average daily net assets. This arrangement expires on July 31, 2024, 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.
The expense reductions described above amounted to $21,258 for the year ended October 31, 2022.
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 year ended October 31, 2022, were equivalent to a net annual effective rate of 0.53% of the fund’s average daily managed net 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 year ended October 31, 2022, 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.
44 JOHN HANCOCK Income Securities Trust | ANNUAL REPORT  

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, 2022 and December 31, 2022, up to 10% of its outstanding common shares as of December 31, 2021. The share repurchase plan will remain in effect between January 1, 2022 and December 31, 2022.
During the years ended October 31, 2022 and 2021, 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.
Note 6Leverage risk
The fund utilizes a Liquidity Agreement (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 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 Liquidity Agreement (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 October 31, 2022 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 October 31, 2022, the LA balance of $91,300,000 was comprised of $55,742,242 from the line of credit and
  ANNUAL REPORT | JOHN HANCOCK Income Securities Trust 45

$35,557,758 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 one month LIBOR (London Interbank Offered Rate) plus 0.600% and is payable monthly on the aggregate balance of the drawdowns outstanding under the LA. As of October 31, 2022, the fund had an aggregate balance of $91,300,000 at an interest rate of 4.40%, which is reflected in the Liquidity agreement on the Statement of assets and liabilities. During the year ended October 31, 2022, the average balance of the LA and the effective average interest rate were $91,300,000 and 1.86%, 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.
Due to the anticipated discontinuation of LIBOR, as discussed in Note 8, the LA may be amended to remove LIBOR as the reference rate for interest and to replace LIBOR with an alternative reference rate for interest mutually agreed upon by the fund and SSB. However, there remains uncertainty regarding the future utilization of LIBOR and the nature of any replacement rate and the potential effect of a transition away from LIBOR on the fund and/or the LA cannot yet be fully determined.
Note 8LIBOR Discontinuation Risk
The LA utilizes LIBOR as the reference or benchmark rate for interest rate calculations. LIBOR is a measure of the average interest rate at which major global banks can borrow from one another. Following allegations of rate manipulation and concerns regarding its thin liquidity, in July 2017, the U.K. Financial Conduct Authority, which regulates LIBOR, announced that it will stop encouraging banks to provide the quotations needed to sustain LIBOR. The ICE Benchmark Administration Limited, the administrator of LIBOR, ceased publishing most LIBOR maturities, including some US LIBOR maturities, on December 31, 2021, and is expected to cease publishing the remaining and most liquid US LIBOR maturities on June 30, 2023. It is expected that market participants such as the fund and SSB will transition to the use of alternative reference or benchmark rates prior to the applicable LIBOR publication cessation date. However, although regulators have encouraged the development and adoption of alternative rates, such as the Secured Overnight Financing Rate ("SOFR"), there is currently no definitive information regarding the future utilization of LIBOR or of any particular replacement rate.
Although the transition process away from LIBOR has become increasingly well-defined in advance of the anticipated discontinuation dates, the impact on the LA remains uncertain. It is expected that market participants will amend financial instruments referencing LIBOR, such as the LA, to include fallback provisions and other measures that contemplate the discontinuation of LIBOR or other similar market disruption events, but neither the effect of the transition process nor the viability of such measures is known. To facilitate the transition of legacy derivatives contracts referencing LIBOR, the International Swaps and Derivatives Association, Inc. launched a
46 JOHN HANCOCK Income Securities Trust | ANNUAL REPORT  

protocol to incorporate fallback provisions. However, there are obstacles to converting certain longer term securities and transactions to a new benchmark or benchmarks and the effectiveness of one alternative reference rate versus multiple alternative reference rates in new or existing financial instruments and products has not been determined. Certain proposed replacement rates to LIBOR, such as SOFR, which is a broad measure of secured overnight US Treasury repo rates, are materially different from LIBOR, and changes in the applicable spread for financial instruments transitioning away from LIBOR will need to be made to accommodate the differences. Furthermore, the risks associated with the expected discontinuation of LIBOR and transition to replacement rates may be exacerbated if an orderly transition to an alternative reference rate is not completed in a timely manner.
As market participants transition away from LIBOR, LIBOR’s usefulness may deteriorate. The transition process may lead to increased volatility and illiquidity in markets that currently rely on LIBOR to determine interest rates. LIBOR’s deterioration may adversely affect the liquidity and/or market value of securities that use LIBOR as a benchmark interest rate. The use of an alternative reference rate, or the transition process to an alternative reference rate, may result in increases to the interest paid by the fund pursuant to the LA and, therefore, may adversely affect the fund’s performance.
Note 9Purchase and sale of securities
Purchases and sales of securities, other than short-term investments and U.S. Treasury obligations, amounted to $98,051,488 and $120,778,662, respectively, for the year ended October 31, 2022. Purchases and sales of U.S. Treasury obligations aggregated $156,146,670 and $127,660,713, respectively, for the year ended October 31, 2022.
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 11Coronavirus (COVID-19) pandemic
The COVID-19 disease has resulted in significant disruptions to global business activity. A widespread health crisis such as a global pandemic could cause substantial market volatility, exchange-trading suspensions, and closures, which may lead to less liquidity in certain instruments, industries, sectors or the markets generally, and may ultimately affect fund performance.
Note 12New accounting pronouncement
In March 2020, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU), ASU 2020-04, which provides optional, temporary relief with respect to the financial reporting of contracts subject to certain types of modifications due to the planned discontinuation of the LIBOR and other IBOR-based reference rates as of the end of 2021. The temporary relief provided by ASU 2020-04 is effective for certain reference rate-related contract modifications that occur during the period March 12, 2020 through December 31, 2022. Management expects that the adoption of the guidance will not have a material impact to the financial statements.

Investment objective, principal investment strategies, and principal risks

Unaudited
Investment Objectives
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 Advisor may also take into consideration environmental, social, and/or governance (“ESG”) factors, alongside other relevant factors, as part of its investment selection process. 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.
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.
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.
50 JOHN HANCOCK INCOME SECURITIES TRUST | ANNUAL REPORT  

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.
Cybersecurity and operational 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.
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.
As a result of continued political tensions and armed conflicts, including the Russian invasion of Ukraine commencing in February of 2022, the extent and ultimate result of which are unknown at this time, the United States and the European Union, along with the regulatory bodies of a number of countries, have imposed economic sanctions on certain Russian corporate entities and individuals, and certain sectors of Russia’s economy, which may result in, among other things, the continued devaluation of Russian currency, a downgrade in the country’s credit rating, and/or a decline in the value and liquidity of Russian securities, property or interests. These sanctions could also result in the immediate freeze of Russian securities and/or funds invested in prohibited assets, impairing the ability of a fund to buy, sell, receive or deliver those securities and/or assets. Economic sanctions and other actions against Russian institutions, companies, and individuals resulting from the ongoing conflict may also have a substantial negative impact on other economies and securities markets both regionally and globally, as well as on companies with operations in the conflict region, the extent to which is unknown at this time.
A widespread health crisis such as a global pandemic could cause substantial market volatility, exchange trading suspensions and closures, and affect fund performance. For example, the coronavirus disease (COVID-19) has resulted and may continue to result in significant disruptions to global business activity and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. The impact of a health crisis and other epidemics and pandemics that may arise in the future, could affect the global economy in ways that cannot necessarily be foreseen at the present time. A health crisis may exacerbate other preexisting political, social, and economic risks. Any such impact could adversely affect the fund’s performance, resulting in losses to your investment.
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 investing in instruments that have certain ESG characteristics, as determined by the manager, carries the risk that the fund may
  ANNUAL REPORT | JOHN HANCOCK INCOME SECURITIES TRUST 51

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 scores or exclude companies with high ESG scores 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 (“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.
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. If applicable, depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.
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 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 6 —Leverage risk” above.
LIBOR discontinuation risk. The publication of the London Interbank Offered Rate (LIBOR), which many debt securities, derivatives and other financial instruments use as the reference or benchmark rate for interest rate calculations, was discontinued for certain maturities as of December 31, 2021, and is expected to be discontinued on June 30, 2023 for the remaining maturities. The transition process away from LIBOR may lead to increased volatility and illiquidity in markets that currently rely on LIBOR to determine interest rates, and the eventual use of an alternative reference rate may adversely affect the fund’s performance. In addition, the usefulness of LIBOR may deteriorate in the period leading up to its discontinuation, which could adversely affect the liquidity or market value of securities that use LIBOR.
52 JOHN HANCOCK INCOME SECURITIES TRUST | ANNUAL REPORT  

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 to satisfy redemptions 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.
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.

ADDITIONAL INFORMATION

Unaudited
The fund is a closed-end, diversified management investment company, common shares of which were initially offered to the public on February 14, 1973, and are publicly traded on the New York Stock Exchange (the NYSE).
Dividends and distributions
During the year ended October 31, 2022, distributions from net investment income totaling $0.6954 per share and distributions from capital gains totaling $0.2247 per share were paid to shareholders. The dates of payments and the amounts per share were as follows:
Payment Date Income Distributions
December 31, 2021 $0.2276
March 31, 2022 0.1780
June 30, 2022 0.1682
September 30, 2022 0.1216
Total $0.6954
    
Payment Date Additional Distributions
December 31, 2021 $0.2247

 
Total $0.9201
Dividend reinvestment plan
The fund’s Dividend Reinvestment Plan (the Plan) provides that distributions of dividends and capital gains are automatically reinvested in common shares of the fund by Computershare Trust Company, N.A. (the Plan Agent). Every shareholder holding at least one full share of the fund is entitled to participate in the Plan. In addition, every shareholder who became a shareholder of the fund after June 30, 2011, and holds at least one full share of the fund will be automatically enrolled in the Plan. Shareholders may withdraw from the Plan at any time and shareholders who do not participate in the Plan will receive all distributions in cash.
If the fund declares a dividend or distribution payable either in cash or in common shares of the fund and the market price of shares on the payment date for the distribution or dividend equals or exceeds the fund’s net asset value per share (NAV), the fund will issue common shares to participants at a value equal to the higher of NAV or 95% of the market price. The number of additional shares to be credited to each participant’s account will be determined by dividing the dollar amount of the distribution or dividend by the higher of NAV or 95% of the market price. If the market price is lower than NAV, or if dividends or distributions are payable only in cash, then participants will receive shares purchased by the Plan Agent on participants’ behalf on the NYSE or otherwise on the open market. If the market price exceeds NAV before the Plan Agent has completed its purchases, the average per share purchase price may exceed NAV, resulting in fewer shares being acquired than if the fund had issued new shares.
There are no brokerage charges with respect to common shares issued directly by the fund. However, whenever shares are purchased or sold on the NYSE or otherwise on the open market, each participant will pay a pro rata portion of brokerage trading fees, currently $0.05 per share purchased or sold. Brokerage trading fees will be deducted from amounts to be invested.
The reinvestment of dividends and net capital gains distributions does not relieve participants of any income tax that may be payable on such dividends or distributions.
54 JOHN HANCOCK INCOME SECURITIES TRUST  | ANNUAL REPORT  

Shareholders participating in the Plan may buy additional shares of the fund through the Plan at any time in amounts of at least $50 per investment, up to a maximum of $10,000, with a total calendar year limit of $100,000. Shareholders will be charged a $5 transaction fee plus $0.05 per share brokerage trading fee for each order. Purchases of additional shares of the fund will be made on the open market. Shareholders who elect to utilize monthly electronic fund transfers to buy additional shares of the fund will be charged a $2 transaction fee plus $0.05 per share brokerage trading fee for each automatic purchase. Shareholders can also sell fund shares held in the Plan account at any time by contacting the Plan Agent by telephone, in writing or by visiting the Plan Agent’s website at www.computershare.com/investor. The Plan Agent will mail a check (less applicable brokerage trading fees) on settlement date. Pursuant to regulatory changes, effective September 5, 2017, the settlement date is changed from three business days after the shares have been sold to two business days after the shares have been sold. If shareholders choose to sell shares through their stockbroker, they will need to request that the Plan Agent electronically transfer those shares to their stockbroker through the Direct Registration System.
Shareholders participating in the Plan may withdraw from the Plan at any time by contacting the Plan Agent by telephone, in writing or by visiting the Plan Agent’s website at www.computershare.com/investor. Such termination will be effective immediately if the notice is received by the Plan Agent prior to any dividend or distribution record date; otherwise, such termination will be effective on the first trading day after the payment date for such dividend or distribution, with respect to any subsequent dividend or distribution. If shareholders withdraw from the Plan, their shares will be credited to their account; or, if they wish, the Plan Agent will sell their full and fractional shares and send the shareholders the proceeds, less a transaction fee of $5 and less brokerage trading fees of $0.05 per share. If a shareholder does not maintain at least one whole share of common stock in the Plan account, the Plan Agent may terminate such shareholder’s participation in the Plan after written notice. Upon termination, shareholders will be sent a check for the cash value of any fractional share in the Plan account, less any applicable broker commissions and taxes.
Shareholders who hold at least one full share of the fund may join the Plan by notifying the Plan Agent by telephone, in writing or by visiting the Plan Agent’s website at www.computershare.com/investor. If received in proper form by the Plan Agent before the record date of a dividend, the election will be effective with respect to all dividends paid after such record date. If shareholders wish to participate in the Plan and their shares are held in the name of a brokerage firm, bank or other nominee, shareholders should contact their nominee to see if it will participate in the Plan. If shareholders wish to participate in the Plan, but their brokerage firm, bank or other nominee is unable to participate on their behalf, they will need to request that their shares be re-registered in their own name, or they will not be able to participate. The Plan Agent will administer the Plan on the basis of the number of shares certified from time to time by shareholders as representing the total amount registered in their name and held for their account by their nominee.
Experience under the Plan may indicate that changes are desirable. Accordingly, the fund and the Plan Agent reserve the right to amend or terminate the Plan. Participants generally will receive written notice at least 90 days before the effective date of any amendment. In the case of termination, participants will receive written notice at least 90 days before the record date for the payment of any dividend or distribution by the fund.

EVALUATION OF ADVISORY AND SUBADVISORY AGREEMENTS BY THE BOARD OF TRUSTEES

This section describes the evaluation by the Board of Trustees (the Board) of John Hancock Income Securities Trust (the fund) of the Advisory Agreement (the Advisory Agreement) with John Hancock Investment Management LLC (the Advisor) and the Subadvisory Agreement (the Subadvisory Agreement) with Manulife Investment Management (US) LLC (the Subadvisor). The Advisory Agreement and Subadvisory Agreement are collectively referred to as the Agreements. Prior to the June 21-23, 2022 videoconference1 meeting at which the Agreements were approved, the Board also discussed and considered information regarding the proposed continuation of the Agreements at the videoconference meeting held on May 24-25, 2022. 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 to evaluate and discuss the information presented, including with counsel to the Independent Trustees and a third-party consulting firm.
Approval of Advisory and Subadvisory Agreements
At videoconference meetings held on June 21-23, 2022, the Board, including the Trustees who are not parties to any Agreement or considered to be interested persons of the fund under the 1940 Act, reapproved for an annual period the continuation of the Advisory Agreement between the fund and the Advisor and the Subadvisory Agreement between the Advisor and the Subadvisor with respect to the fund.
In considering the Advisory Agreement and the Subadvisory Agreement, the Board received in advance of the meetings a variety of materials relating to the fund, the Advisor and the Subadvisor, including comparative performance, fee and expense information for a peer group of similar funds prepared by an independent third-party provider of fund data, performance information for an applicable benchmark index; and other pertinent information, such as the market premium and discount information, and, with respect to the Subadvisor, comparative performance information for comparably managed accounts, as applicable, and other information provided by the Advisor and the Subadvisor regarding the nature, extent and quality of services provided by the Advisor and the Subadvisor under their respective Agreements, as well as information regarding the Advisor’s revenues and costs of providing services to the fund and any compensation paid to affiliates of the Advisor. At the meetings at which the renewal of the Advisory Agreement and Subadvisory Agreement are considered, particular focus is given to information concerning fund performance, comparability of fees and total expenses, and profitability. However, the Board noted that the evaluation process with respect to the Advisor and the Subadvisor is an ongoing one. In this regard, the Board also took into account discussions with management and information provided to the Board (including its various committees) at prior meetings with respect to the services provided by the Advisor and the Subadvisor to the fund, including quarterly performance reports prepared by management containing reviews of investment results and prior presentations from the Subadvisor with respect to the fund. The information received and considered by the Board in connection with the May and June meetings and throughout the year was both written and oral. The Board noted the affiliation of the Subadvisor with the Advisor, noting any potential conflicts of interest. The Board also considered the nature, quality, and extent of non-advisory services, if any, to be provided to the fund by the Advisor’s affiliates. The Board considered the Advisory Agreement and the Subadvisory Agreement separately in the course of its review. In doing so, the Board noted the respective roles of the Advisor and Subadvisor in providing services to the fund.

1On June 19, 2020, as a result of health and safety measures put in place to combat the global COVID-19 pandemic, the Securities and Exchange Commission issued an exemptive order (the “Order”) pursuant to Sections 6(c) and 38(a) of the Investment Company Act of 1940, as amended (the “1940 Act”), that temporarily exempts registered investment management companies from the in-person voting requirements under the 1940 Act, subject to certain requirements, including that votes taken pursuant to the Order are ratified at the next in-person meeting. The Board determined that reliance on the Order was necessary or appropriate due to the circumstances related to current or potential effects of COVID-19 and therefore, the Board’s May and June meetings were held via videoconference in reliance on the Order. This exemptive order supersedes, in part, a similar earlier exemptive order issued by the SEC.
  ANNUAL REPORT  | JOHN HANCOCK INCOME SECURITIES TRUST 57

Throughout the process, the Board asked questions of and requested additional information from management. The Board is assisted by counsel for the fund and the Independent Trustees are 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 Agreements and discussed the proposed continuation of the Agreements in private sessions with their independent legal counsel at which no representatives of management were present.
Approval of Advisory Agreement
In approving the Advisory Agreement with respect to the fund, the Board, including the Independent Trustees, considered a variety of factors, including those discussed below. The Board also considered other factors (including conditions and trends prevailing generally in the economy, the securities markets, and the industry) and did not treat any single factor as determinative, and each Trustee may have attributed different weights to different factors. The Board’s conclusions may be based in part on its consideration of the advisory and subadvisory arrangements in prior years and on the Board’s ongoing regular review of fund performance and operations throughout the year.
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 fund’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 programs, liquidity management 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, including, but not limited to, general supervision of and coordination of the services provided by the Subadvisor, and is also responsible for monitoring and reviewing the activities of the Subadvisor and 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 entrepreneurial risk in sponsoring new funds and ongoing risks including investment, operational, enterprise, litigation, regulatory and compliance risk with respect to all funds.
The Board also considered the differences between the Advisor’s services to the fund and the services it provides to other clients that are not closed-end funds, including, for example, the differences in services related to the regulatory and legal obligations of closed-end funds.
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 fund and of the other funds 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 fund’s affairs and its subadvisory relationship, the Advisor’s oversight and monitoring of the Subadvisor’s investment performance and compliance programs, such as the Subadvisor’s compliance with fund policies and objectives, review of brokerage matters, including with respect to trade allocation and best execution and the Advisor’s timeliness in responding to performance issues;
(b) the background, qualifications and skills of the Advisor’s personnel;
58 JOHN HANCOCK INCOME SECURITIES TRUST  | ANNUAL REPORT  

(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, as well as the Advisor’s oversight of any securities lending activity, its monitoring of class action litigation and collection of class action settlements on behalf of the fund, and bringing loss recovery actions on behalf of the fund;
(e) the financial condition of the Advisor and whether it has the financial wherewithal 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 investor experience with the fund; and
(g) the Advisor’s reputation and experience in serving as an investment advisor to the fund and the benefit to shareholders of investing in funds that are part of a family of funds offering a variety of investments.
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 comparable funds, if any, as included in the report prepared by an independent third-party provider of fund data;
(d) took into account the Advisor’s analysis of the fund’s performance; and
(e) considered the fund’s share performance and premium/discount information.
The Board noted that while it found the data provided by the independent third-party generally 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 selection of the peer group. The Board noted that, based on its net asset value, the fund outperformed its benchmark index for the one-, three-, five- and ten-year periods ended December 31, 2021. The Board also reviewed comparisons of the fund’s performance to the peer group, but noted the limited size of the peer group. The Board took into account management’s discussion of the fund’s performance, including the favorable performance relative to the benchmark index for the one-, three-, five- and ten-year periods. The Board concluded that the fund’s performance has generally been in line with or outperformed the fund’s benchmark index.
Fees and expenses. The Board reviewed comparative information prepared by an independent third-party provider of fund data, including, among other data, the fund’s contractual and net management fees (and subadvisory fees, to the extent available) and total expenses as compared to similarly situated investment companies deemed to be comparable to the fund in light of the nature, extent and quality of the management and advisory and subadvisory services provided by the Advisor and the Subadvisor. The Board considered the fund’s ranking within a smaller group of peer funds chosen by the independent third-party provider, as well as the fund’s ranking within a broader group of funds. In comparing the fund’s contractual and net management fees to those of comparable funds, the Board noted that such fees include both advisory and administrative costs.
  ANNUAL REPORT  | JOHN HANCOCK INCOME SECURITIES TRUST 59

The Board also took into account the impact of leverage on fund expenses. The Board took into account the management fee structure, including that management fees for the fund were based on the fund’s total managed assets, which are attributable to common stock and borrowings. The Board noted that net management fees and net total expenses for the fund are higher than the peer group median.
The Board took into account management’s discussion of the fund’s expenses. The Board also took into account management’s discussion with respect to the overall management fee and the fees of the Subadvisor, including the amount of the advisory fee retained by the Advisor after payment of the subadvisory fee, in each case in light of the services rendered for those amounts and the risks undertaken by the Advisor. The Board also noted that the Advisor pays the subadvisory fee. In addition, the Board took into account that management had agreed to implement an overall fee waiver across the complex, including the fund, which is discussed further below. The Board also noted that, in addition, the Advisor is currently waiving fees and/or reimbursing expenses with respect to the fund and that the fund has breakpoints in its contractual management fee schedule that reduces management fees as assets increase. The Board reviewed information provided by the Advisor concerning the investment advisory fee charged by the Advisor or one of its advisory affiliates to other clients (including other funds in the John Hancock Fund Complex) having similar investment mandates, if any. The Board considered any differences between the Advisor’s and Subadvisor’s services to the fund and the services they provide to other comparable clients or funds. The Board concluded that the advisory fee paid with respect to the fund is 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 to be provided and the profits to be realized by the Advisor and its affiliates (including the Subadvisor) from the Advisor’s relationship with the fund, the Board:
(a) reviewed financial information of the Advisor;
(b) reviewed and considered information presented by the Advisor regarding the net profitability to the Advisor and its affiliates with respect to the fund;
(c) received and reviewed profitability information with respect to the John Hancock Fund Complex as a whole and with respect to the fund;
(d) received information with respect to the Advisor’s allocation methodologies used in preparing the profitability data and considered that the advisor hired an independent third-party consultant to provide an analysis of the Advisor’s allocation methodologies;
(e) considered that the Advisor also provides administrative services to the fund on a cost basis pursuant to an administrative services agreement;
(f) noted that the fund’s Subadvisor is an affiliate of the Advisor;
(g) noted that the Advisor also derives reputational and other indirect benefits from providing advisory services to the fund;
(h) noted that the subadvisory fees for the fund are paid by the Advisor;
(i) considered the Advisor’s ongoing costs and expenditures necessary to improve services, meet new regulatory and compliance requirements, and adapt to other challenges impacting the fund industry; and
(j) considered that the Advisor should be entitled to earn a reasonable level of profits in exchange for the level of services it provides to the fund and the risks that it assumes as Advisor, including entrepreneurial, operational, reputational, litigation and regulatory risk.
Based upon its review, the Board concluded that the level of profitability, if any, of the Advisor and its affiliates (including the Subadvisor) from their relationship with the fund was reasonable and not excessive.
60 JOHN HANCOCK INCOME SECURITIES TRUST  | ANNUAL REPORT  

Economies of scale. In considering the extent to which the fund may realize any economies of scale and whether fee levels reflect these economies of scale for the benefit of the fund shareholders, the Board noted that the fund has a limited ability to increase its assets as a closed-end fund. 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 and in supervising the Subadvisor.
The Board also considered potential economies of scale that may be realized by the fund as part of the John Hancock Fund Complex. Among them, the Board noted that the Advisor has contractually agreed to waive a portion of its management fee and/or reimburse expenses for certain funds of the John Hancock Fund Complex, including the fund (the participating portfolios). This waiver is based upon aggregate net assets of all the participating portfolios. 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. The Board reviewed the fund’s advisory fee structure and concluded that: (i) the fund’s fee structure contains breakpoints at the subadvisory fee level and that such breakpoints are reflected as breakpoints in the advisory fees for the fund; and (ii) although economies of scale cannot be measured with precision, these arrangements permit shareholders of the fund to benefit from economies of scale if the fund grows. The Board also took into account management’s discussion of the fund’s advisory fee structure. The Board also considered the Advisor’s overall operations and its ongoing investment in its business in order to expand the scale of, and improve the quality of, its operations that benefit the fund. The Board determined that the management fee structure for the fund was reasonable.
Approval of Subadvisory Agreement
In making its determination with respect to approval of the Subadvisory Agreement, the Board reviewed:
(1) information relating to the Subadvisor’s business, including current subadvisory services to the fund (and other funds in the John Hancock Fund Complex);
(2) the historical and current performance of the fund and comparative performance information relating to an applicable benchmark index and comparable funds; and
(3) the subadvisory fee for the fund, including any breakpoints, and to the extent available, comparable fee information prepared by an independent third party provider of fund data.
Nature, extent, and quality of services. With respect to the services provided by the Subadvisor, the Board received information provided to the Board by the Subadvisor, including the Subadvisor’s Form ADV, as well as took into account information presented throughout the past year. The Board considered the Subadvisor’s current level of staffing and its overall resources, as well as received information relating to the Subadvisor’s compensation program. The Board reviewed the Subadvisor’s history and investment experience, as well as information regarding the qualifications, background, and responsibilities of the Subadvisor’s investment and compliance personnel who provide services to the fund. The Board also considered, among other things, the Subadvisor’s compliance program and any disciplinary history. The Board also considered the Subadvisor’s risk assessment and monitoring process. The Board reviewed the Subadvisor’s regulatory history, including whether it was involved in any regulatory actions or investigations as well as material litigation, and any settlements and amelioratory actions undertaken, as appropriate. The Board noted that the Advisor conducts regular, periodic reviews of the Subadvisor and its operations, including regarding investment processes and organizational and staffing matters. The Board also noted that the fund’s CCO and his staff conduct regular, periodic compliance reviews with the Subadvisor and present reports to the Independent Trustees regarding the same, which includes evaluating the regulatory compliance systems of the Subadvisor and procedures reasonably designed to assure compliance with the federal securities laws. The Board also took into account the financial condition of the Subadvisor.
The Board considered the Subadvisor’s investment process and philosophy. The Board took into account that the Subadvisor’s responsibilities include the development and maintenance of an investment program for the fund that is consistent with the fund’s investment objective, the selection of investment securities and the placement of
  ANNUAL REPORT  | JOHN HANCOCK INCOME SECURITIES TRUST 61

orders for the purchase and sale of such securities, as well as the implementation of compliance controls related to performance of these services. The Board also received information with respect to the Subadvisor’s brokerage policies and practices, including with respect to best execution and soft dollars.
Subadvisor compensation. In considering the cost of services to be provided by the Subadvisor and the profitability to the Subadvisor of its relationship with the fund, the Board noted that the fees under the Subadvisory Agreement are paid by the Advisor and not the fund. The Board also received information and took into account any potential conflicts of interest the Advisor might have in connection with the Subadvisory Agreement.
In addition, the Board considered other potential indirect benefits that the Subadvisor and its affiliates may receive from the Subadvisor’s relationship with the fund, such as the opportunity to provide advisory services to additional funds in the John Hancock Fund Complex and reputational benefits.
Subadvisory fees. The Board considered that the fund pays an advisory fee to the Advisor and that, in turn, the Advisor pays subadvisory fees to the Subadvisor. As noted above, the Board also considered the fund’s subadvisory fee as compared to similarly situated investment companies deemed to be comparable to the fund as included in the report prepared by the independent third party provider of fund data, to the extent available. The Board noted that the limited size of the Lipper peer group was not sufficient for comparative purposes. The Board also took into account the subadvisory fee paid by the Advisor to the Subadvisor with respect to the fund and compared them to fees charged by the Subadvisor to manage other subadvised portfolios and portfolios not subject to regulation under the 1940 Act, as applicable.
Subadvisor performance. As noted above, the Board considered the fund’s performance as compared to the fund’s peer group median and the benchmark index and noted that the Board reviews information about the fund’s performance results at its regularly scheduled meetings. The Board noted the Advisor’s expertise and resources in monitoring the performance, investment style and risk-adjusted performance of the Subadvisor. The Board was mindful of the Advisor’s focus on the Subadvisor’s performance. The Board also noted the Subadvisor’s long-term performance record for similar accounts, as applicable.
The Board’s decision to approve the Subadvisory Agreement was based on a number of determinations, including the following:
(1) the Subadvisor has extensive experience and demonstrated skills as a manager;
(2) the fund’s performance, based on net asset value, has generally been in line with or outperformed the fund’s benchmark index;
(3) the subadvisory fees are reasonable in relation to the level and quality of services being provided under the Subadvisory Agreement; and
(4) the subadvisory fee breakpoints are reflected as breakpoints in the advisory fees for the fund in order to permit shareholders to benefit from economies of scale if the fund grows.
* * *
Based on the Board’s evaluation of all factors that the Board deemed to be material, including those factors described above, the Board, including the Independent Trustees, concluded that renewal of the Advisory Agreement and the Subadvisory Agreement would be in the best interest of the fund and its shareholders. Accordingly, the Board, and the Independent Trustees voting separately, approved the Advisory Agreement and Subadvisory Agreement for an additional one-year period.

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

The trust'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 funds. 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 trust'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.

Conflicts of Interest. When a portfolio manager is responsible for the management of more than one account, the potential arises for the portfolio manager to favor one account over another. The principal types of potential conflicts of interest that may arise are discussed below. For the reasons outlined below, the Fund does not believe that any material conflicts are likely to arise out of a portfolio manager's responsibility for the management of the Fund as well as one or more other accounts. The Advisor and Subadvisor have adopted procedures that are intended to monitor compliance with the policies referred to in the following paragraphs. Generally, the risks of such conflicts of interests are increased to the extent that a portfolio manager has a financial incentive to favor one account over another. The Advisor and Subadvisor have structured their compensation arrangements in a manner that is intended to limit such potential for conflicts of interests. See "Compensation of Portfolio Managers" below.

A portfolio manager could favor one account over another in allocating new investment opportunities that have limited supply, such as initial public offerings and private placements. If, for example, an initial public offering that was expected to appreciate in value significantly shortly after the offering was allocated to a single account, that account may be expected to have better investment performance than other accounts that did not receive an allocation on the initial public offering. The Subadvisor has policies that require a portfolio manager to allocate such investment opportunities in an equitable manner and generally to allocate such investments proportionately among all accounts with similar investment objectives.

A portfolio manager could favor one account over another in the order in which trades for the accounts are placed. If a portfolio manager determines to purchase a security for more than one account in an aggregate amount that may influence the market price of the security, accounts that purchased or sold the security first may receive a more favorable price than accounts that made subsequent transactions. The less liquid the market for the security or the greater the percentage that the proposed aggregate purchases or sales represent of average daily trading volume, the greater the potential for accounts that make subsequent purchases or sales to receive a less favorable price. When a portfolio manager intends to trade the same security for more than one account, the policies of the Subadvisor generally require that such trades be "bunched," which means that the trades for the individual accounts are aggregated and each account receives the same price. There are some types of accounts as to which bunching may not be possible for contractual reasons (such as directed brokerage arrangements). Circumstances may also arise where the trader believes that bunching the orders may not result in the best possible price. Where those accounts or circumstances are involved, the Subadvisor will place the order in a manner intended to result in as favorable a price as possible for such client.

A portfolio manager could favor an account if the portfolio manager's compensation is tied to the performance of that account rather than all accounts managed by the portfolio

If, for example, the portfolio manager receives a bonus based upon the performance of certain accounts relative to a benchmark while other accounts are disregarded for this purpose, the portfolio manager will have a financial incentive to seek to have the accounts that determine the portfolio manager's bonus achieve the best possible performance to the possible detriment of other accounts. Similarly, if the Subadvisor receives a performance-based advisory fee, the portfolio manager may favor that account, whether or not the performance of that account directly determines the portfolio manager's compensation. The investment performance on specific accounts is not a factor in determining the portfolio manager's compensation. See "Compensation of Portfolio Managers" below. Neither the Advisor nor the Subadvisor receives a performance-based fee with respect to any of the accounts managed by the portfolio managers.

A portfolio manager could favor an account if the portfolio manager has a beneficial interest in the account, in order to benefit a large client or to compensate a client that had poor returns. For example, if the portfolio manager held an interest in an investment partnership that was one of the accounts managed by the portfolio manager, the portfolio manager would have an economic incentive to favor the account in which the portfolio manager held an interest. The Subadvisor imposes certain trading restrictions and reporting requirements for accounts in which a portfolio manager or certain family members have a personal interest in order to confirm that such accounts are not favored over other accounts.

If the different accounts have materially and potentially conflicting investment objectives or strategies, a conflict of interest may arise. For example, if a portfolio manager purchases a security for one account and sells the same security short for another account, such trading pattern could disadvantage either the account that is long or short. In making portfolio manager assignments, the Subadvisor seeks to avoid such potentially conflicting situations. However, where a portfolio manager is responsible for accounts with differing investment objectives and policies, it is possible that the portfolio manager will conclude that it is in the best interest of one account to sell a portfolio security while another account continues to hold or increase the holding in such security.

Compensation of Portfolio Managers. The Subadvisor has adopted a system of compensation for portfolio managers and others involved in the investment process that is applied systematically among investment professionals. At the Subadvisor, the structure of compensation of investment professionals is currently composed of the following basic components: base salary and short- and long-term incentives. The following describes each component of the compensation package for the individuals identified as a portfolio manager for the Funds.

Base salary. Base compensation is fixed and normally reevaluated on an annual basis. The Subadvisor seeks to set compensation at market rates, taking into account the experience and responsibilities of the investment professional.

Incentives. Only investment professionals are eligible to participate in the short-and long-term incentive plan. Under the plan, investment professionals are eligible for an annual cash award. The plan is intended to provide a competitive level of annual bonus compensation that is tied to the investment professional achieving superior investment performance and aligns the financial incentives of the Subadvisor and the investment professional. Any bonus under the plan is completely discretionary, with a maximum annual bonus that may be well in excess of base salary. Payout of a portion of this bonus may be deferred for up to five years. While the amount of any bonus is discretionary, the following factors are generally used in determining bonuses under the plan:

 

Investment Performance: The investment performance of all accounts managed by the investment professional over one, three and five-year periods are considered. With respect to fixed income accounts, relative yields are also used to measure performance. The pre-tax performance of each account is measured relative to an appropriate benchmark and universe as identified in the table below.

Financial Performance: The profitability of the Subadvisor and its parent company are also considered in determining bonus awards.

Non-Investment Performance: To a lesser extent, intangible contributions, including the investment professional's support of client service and sales activities, new fund/strategy idea generation, professional growth and development, and management, where applicable, are also evaluated when determining bonus awards.

In addition to the above, compensation may also include a revenue component for an investment team derived from a number of factors including, but not limited to client assets under management, investment performance, and firm metrics.

Manulife Equity Awards. A limited number of senior investment professionals may receive options to purchase shares of Manulife Financial stock. Generally, such option would permit the investment professional to purchase a set amount of stock at the market price on the date of grant. The option can be exercised for a set period (normally a number of years or until termination of employment) and the investment professional would exercise the option if the market value of Manulife Financial stock increases. Some investment professionals may receive restricted stock grants, where the investment professional is entitled to receive the stock at no or nominal cost, provided that the stock is forgone if the investment professional's employment is terminated prior to a vesting date.

Deferred Incentives. Investment professionals may receive deferred incentives which are fully invested in strategies managed by the team/individuals as well as other Manulife Asset Management strategies.

The Subadvisor also permits investment professionals to participate on a voluntary basis in a deferred compensation plan, under which the investment professional may elect on an annual basis to defer receipt of a portion of their compensation until retirement. Participation in the plan is voluntary.
