A message to shareholders

Dear shareholder,

Financial markets are by their very nature unpredictable, but few market observers could have imagined the dramatic twists and turns that would come to characterize 2016. Last year began with a sharp stock market correction in the United States as investors worried about the toll that rapidly declining oil and commodity prices would have on the energy sector and the broader economy. It was short lived, as oil prices soon reversed course and stocks rallied, kicking off what would become the eighth straight year of stock market gains. Returns accelerated further after the presidential election victory of Donald Trump as investors quickly began to price in the prospects for a rollback of industry regulations, an increase in fiscal spending, higher borrowing rates, and higher inflation.

Internationally, developed equity markets posted muted gains for the year, while several emerging markets benefited from the rebound in oil and commodity prices. A strengthening U.S. dollar will represent a headwind for investors in some of these markets as returns are translated back into U.S. dollars. Emerging economies repaying increasingly more expensive dollar-denominated debt could also encounter challenges.

Should the markets sustain their volatile nature in 2017, one of your best resources is your financial advisor, who can help ensure your portfolio is sufficiently diversified to meet your long-term objectives and to withstand the inevitable bumps along the way.

On behalf of everyone at John Hancock Investments, I'd like to take this opportunity to thank you for the continued trust you've placed in us.

Sincerely,

Andrew G. Arnott
President and Chief Executive Officer
John Hancock Investments

Your fund at a glance

INVESTMENT OBJECTIVE

The fund seeks to provide a high level of total return consisting of long-term capital appreciation and current income.

AVERAGE ANNUAL TOTAL RETURNS AS OF 12/31/16 (%)

The S&P Composite 1500 Banks Index is an unmanaged index of banking sector stocks in the S&P 1500 Index.

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

The fund's most recent performance and current annualized distribution rate can be found at jhinvestments.com.

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. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

The performance data contained within this material represents past performance, which does not guarantee future results.

PERFORMANCE HIGHLIGHTS OVER THE LAST TWELVE MONTHS

Rising interest rates supported financials

Financial stocks rallied in the second half of the year and the U.S. Federal Reserve finally raised interest rates on signs of an improving economy.

A small-cap stock focus drove relative results

The fund had a substantial positive return and outperformed its comparative index, the S&P Composite 1500 Banks Index, owing primarily to stock selection in the regional bank sector.

Election results sparked bank stocks

Bank stocks surged postelection on President-elect Trump's plans for fiscal stimulus, tax reform, and decreased regulation.

PORTFOLIO COMPOSITION AS OF 12/31/16 (%)

A note about risks

As is the case with all 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. There is no guarantee prior distribution levels will be maintained and distributions may include a substantial return of capital. Fixed-income investments are subject to interest-rate and credit risk; their value will normally decline as interest rates rise or if a creditor, grantor, or counterparty is unable or unwilling to make principal, interest, or settlement payments. Investments in higher-yielding, lower-rated securities are subject to a higher risk of default. An issuer of securities held by the fund may default, have its credit rating downgraded, or otherwise perform poorly, which may affect fund performance. Liquidity—the extent to which a security may be sold or a derivative position closed without negatively affecting its market value—may be impaired by reduced trading volume, heightened volatility, rising interest rates, and other market conditions. The fund's use of leverage creates additional risks, including greater volatility of the fund's NAV, market price, and returns. There is no assurance that the fund's leverage strategy will be successful. Focusing on a particular industry or sector may increase the fund's volatility and make it more susceptible to market, economic, and regulatory risks as well as other factors affecting those industries or sectors. 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.

Discussion of fund performance

An interview with Portfolio Manager Lisa A. Welch, John Hancock Asset Management a division of Manulife Asset Management (US) LLC

Lisa A. Welch
Portfolio Manager
John Hancock Asset Management

What were the main factors driving market performance and financial stocks over the 12 months ended December 31, 2016?

U.S. equities exhibited steady improvement throughout the year, rebounding from several declining periods to post double-digit gains for the period with the S&P 500 Index finishing up 11.96%. Fears of global deflation and an economic slowdown in China led to a sharp drop in equity and commodity prices early in the period, before the market entered a recovery phase in mid-February. Stocks dipped again briefly in June due to Brexit, the surprise passage of a referendum by the United Kingdom to leave the European Union, before rallying on improving economic data and corporate earnings results. Jobs growth remained steady, with the unemployment rate touching a postfinancial crisis low of 4.6% late in the period, while annual GDP growth perked up to 3.5% in the third quarter—the fastest pace in two years.

The final catalyst that sparked a strong year-end rally was the surprise U.S. presidential election victory of Donald Trump. His plans for fiscal stimulus, tax reform, and lower regulation were greeted warmly. Cyclical stocks tied to the performance of the economy led the markets postelection. Stronger economic data and a better outlook prompted the U.S. Federal Reserve to finally raise its short-term interest-rate target 25 basis points in December and to project a more ambitious pace of tightening in the year ahead. After suffering losses and lagging the broad market earlier in the year, financial stocks led the second-half comeback with the fund's comparative index, the S&P Composite 1500 Banks Index, rising 25.72% for the year, compared with a gain of 13.03% for the S&P 1500 Composite Index.

How can rising interest rates positively affect financial stocks?

Higher rates should benefit most financial companies, especially the majority of those that derive income from spread revenue. Banks will likely see the most positive impact as they have generally positioned their balance sheets to be asset sensitive, meaning they benefit from rising rates.

"Fundamentally sound regional banks held in the portfolio have been able to take advantage of growth opportunities in dynamic economies across the country to expand their footprints."

What trends supported the fund's performance?

The fund had a strong absolute return at net asset value and outperformed its comparative index, due primarily to positive stock selection among regional banks. This segment of the market has been supported by steady loan growth, solid credit quality, and a healthy environment for merger-and-acquisition activity. Fundamentally sound regional banks held in the portfolio have been able to take advantage of growth opportunities in dynamic economies across the country to expand their footprints. During the year, the fund had a number of holdings that were take-out targets, including Avenue Bank, Southwest Bancorp, Inc., and Heritage Oaks Bancorp. Avenue Bank was acquired by Pinnacle Financial Partners and we kept the holding.

What stocks had the greatest positive impact on relative performance?

The leading contributors included Texas-based Cullen/Frost Bankshares and Hancock Holding Company of Mississippi, both of which have significant portfolios of energy loans. These companies' stocks were boosted by a 45% rebound in oil prices during the year. Strategic acquirers Independent Bank Corp. in Massachusetts and Chicago-based MB Financial, Inc. continued to deliver value through acquisitions and organic growth. Lenders that benefit most directly from

"The fund continues to have an overweight position in small and regional banks, as we believe these companies have the best opportunities in the current environment."

higher interest rates, including Comerica Inc. and Zions Bancorporation, were also among the leading individual contributors.

Which holdings had the biggest negative impact for the period?

The fund's significant underweight versus the benchmark in JP Morgan Chase & Co. and Bank of America, Corp., which outperformed the overall bank sector, was a primary detractor from performance. In addition, the fund's exposure to non-bank companies and its non-equity positions negatively affected returns, as U.S. bank equities were the strongest performing group. Alternative asset managers Blackstone Group L.P. and The Carlyle Group, L.P. negatively impacted performance as concerns increased about the tax treatment of these entities' limited partnership structure. We sold Carlyle prior to period end. Business development corporation Fifth Street Finance Corp. was also a negative contributor, as the company experienced credit problems during the year.

How was the fund positioned at the end of the period?

Trading during the year was mostly limited to small position adjustments aimed at rebalancing and taking advantage of attractive relative valuation opportunities. This consisted of trimming or selling positions that had reached our price targets, such as regional bank Prosperity Bancshares, Inc. and

data center REIT Digital Realty Trust, Inc., and adding new positions such as First Hawaiian, Inc., which was spun out of parent BNP Paribas SA in an initial public offering. Certain superregional banks offered attractive valuations during the year and we took advantage of these dislocations to add to positions in Citizens Financial Group, Inc. and Regions Financial Corp. The fund continues to have an overweight position in small and regional banks, as we believe these companies have the best opportunities in the current environment.

Financial stocks are well positioned for growth if interest rates continue to rise. If the new administration is successful in implementing its pro-growth strategies, banks could also benefit from a less stringent regulatory environment. This could free up more capital for productive uses and could potentially reduce regulatory and compliance-related expense. Potential plans for corporate tax cuts would also be beneficial to certain segments of the financial industry, such as regional banks, brokers, life insurers, and asset managers, who currently pay tax rates above the proposed levels.

Notes to financial statements

Note 1 — Organization

John Hancock Financial Opportunities Fund (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 2 — Significant 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 fund's Valuation Policies and Procedures.

In order to value the securities, the fund uses the following valuation techniques: Equity securities held by the fund 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. Debt obligations are valued based on the evaluated prices provided by an independent pricing vendor or from broker-dealers. 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. Swaps are valued using evaluated prices obtained from an independent pricing vendor. Foreign securities are valued in U.S. dollars, based on foreign currency exchange rates supplied by an independent pricing vendor.

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

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 fund's Pricing Committee following procedures established 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. Trading in foreign securities may be completed before the scheduled daily close of trading on the NYSE. Significant events at the issuer or market level may affect the values of securities between the time when the valuation of the securities is generally determined and the close of the NYSE. If a significant event occurs, these securities may be fair valued, as determined in good faith by the fund's Pricing Committee, following procedures established by the Board of Trustees. The fund uses fair value adjustment factors provided by an independent pricing vendor to value certain foreign securities in order to adjust for events that may occur between the close of foreign exchanges or markets and the close of the NYSE.

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

ANNUAL REPORT   |   JOHN HANCOCK FINANCIAL OPPORTUNITIES FUND       19

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 following is a summary of the values by input classification of the fund's investments as of December 31, 2016, by major security category or type:

Yield	Decrease	Increase

Repurchase agreements. The fund may enter into repurchase agreements. When the fund enters into a repurchase agreement, it receives collateral that is held in a segregated account by the fund's custodian. The collateral amount is marked-to-market and monitored on a daily basis to ensure that the collateral held is in an amount not less than the principal amount of the repurchase agreement plus any accrued interest. Collateral received by the fund for repurchase agreements is disclosed in the Fund's investments as part of the caption related to the repurchase agreement.

Repurchase agreements are typically governed by the terms and conditions of the Master Repurchase Agreement and/or Global Master Repurchase Agreement (collectively, MRA). Upon an event of default, the non-defaulting party may close out all transactions traded under the MRA and net amounts owed. Absent an event of default, assets and liabilities resulting from repurchase agreements are not offset in the Statement of assets and liabilities. In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the collateral value may decline or the counterparty may have insufficient assets to pay back claims resulting from close-out of the transactions.

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 the ex-date, except for dividends of 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. Distributions received on securities that represent a tax return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain if amounts are estimable. Foreign taxes are provided for based on the fund's understanding of the tax rules and rates that exist in the foreign markets in which it invests. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds from litigation.

Foreign currency translation. Assets, including investments and liabilities denominated in foreign currencies, are translated into U.S. dollar values each day at the prevailing exchange rate. Purchases and sales of securities, income and expenses are translated into U.S. dollars at the prevailing exchange rate on the date of the transaction. The effect of changes

ANNUAL REPORT   |   JOHN HANCOCK FINANCIAL OPPORTUNITIES FUND       21

in foreign currency exchange rates on the value of securities is reflected as a component of the realized and unrealized gains (losses) on investments.

Funds that invest internationally generally carry more risk than funds that invest strictly in U.S. securities. Risks can result from differences in economic and political conditions, regulations, market practices (including higher transaction costs), accounting standards and other factors. Foreign investments are also subject to a decline in the value of a foreign currency versus the U.S. dollar, which reduces the dollar value of securities denominated in that currency.

Foreign taxes. The fund may be subject to withholding tax on income and/or capital gains or repatriation taxes imposed by certain countries in which the fund invests. Taxes are accrued based upon investment income, realized gains or unrealized appreciation.

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.

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.

As of December 31, 2016, 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.

Managed distribution plan. In March 2010, the Board of Trustees approved a managed distribution plan. On July 1, 2015, the Board of Trustees approved an amendment to the managed distribution plan (the Managed Distribution Plan). Under the current Managed Distribution Plan, the fund makes quarterly distributions of an amount equal to $0.3701 per share.

Distributions under the Managed Distribution Plan may consist of net investment income, net realized capital gains and, to the extent necessary, return of capital. Return of capital distributions may be necessary when the fund's net investment income and net capital gains are insufficient to meet the minimum distribution. In addition, the fund also may make additional distributions to avoid federal income and excise taxes.

The Board of Trustees may terminate or reduce the amount distributed under the Managed Distribution Plan at any time. The termination or reduction may have an adverse effect on the market price of the fund's shares.

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 under the Managed Distribution Plan described above. The tax character of distributions for the year ended December 31, 2016, two-month period ended December 31, 2015 and year ended October 31, 2015 was as follows:

	December 31, 2016	December 31, 2015	October 31, 2015
Ordinary income	$7,535,904	$1,930,990	$9,352,930
Long-term capital gain	19,981,034	4,936,892	13,967,843
Total	$27,516,938	$6,867,882	$23,320,773

ANNUAL REPORT   |   JOHN HANCOCK FINANCIAL OPPORTUNITIES FUND       22

As of December 31, 2016, the components of distributable earnings on a tax basis consisted of $1,274,937 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.

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 derivative transactions.

Statement of cash flows. 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.

Note 3 — Derivative instruments

The fund may invest in derivatives in order to meet its investment objective. Derivatives include a variety of different instruments that may be traded in the OTC (over-the-counter) market, on a regulated exchange or through a clearing facility. The risks in using derivatives vary depending upon the structure of the instruments, including the use of leverage, optionality, the liquidity or lack of liquidity of the contract, the creditworthiness of the counterparty or clearing organization and the volatility of the position. Some derivatives involve risks that are potentially greater than the risks associated with investing directly in the referenced securities or other referenced underlying instrument. Specifically, the fund is exposed to the risk that the counterparty to an OTC derivatives contract will be unable or unwilling to make timely settlement payments or otherwise honor its obligations. OTC derivatives transactions typically can only be closed out with the other party to the transaction.

Cleared swaps are cleared on an exchange or central clearinghouse. Cleared transactions generally present less counterparty risk to a fund than OTC transactions. The exchange or clearinghouse stands between the fund and the broker to the contract and therefore, credit risk is generally limited to the failure of the clearinghouse and the clearing member.

Cleared swap contracts are subject to clearinghouse rules, including initial and variation margin requirements, daily settlement of obligations and the clearinghouse guarantee of payments to the broker. There is, however, still counterparty risk due to the potential insolvency of the broker with respect to any margin held in the brokers' customer accounts. While clearing members are required to segregate customer assets from their own assets, in the event of insolvency, there may be a shortfall in the amount of margin held by the broker for its clients. Collateral or margin requirements for cleared derivatives are set by the broker or applicable clearinghouse. Margin for exchange-cleared transactions are detailed in the Statement of assets and liabilities as Receivable for centrally cleared swaps. Securities pledged by the fund for exchange-traded and cleared transactions, if any, are identified in the Fund's investments.

Interest rate swaps. Interest rate swaps represent an agreement between the fund and a counterparty to exchange cash flows based on the difference between two interest rates applied to a notional amount. The payment flows are usually netted against each other, with the difference being paid by one party to the other. The fund settles accrued net interest receivable or payable under the swap contracts at specified, future intervals. Swap agreements are privately negotiated in the OTC market or may be executed on a registered commodities exchange (centrally cleared swaps). Swaps are marked-to-market daily and the change in value is recorded as unrealized appreciation/depreciation of swap contracts. A termination payment by the counterparty or the fund is recorded as realized gain or loss, as well as the net periodic payments received or paid by the fund. The value of the swap will typically impose collateral posting obligations on the party that is considered out-of-the-money on the swap.

Entering into swap agreements involves, to varying degrees, elements of credit, market and documentation risk that may amount to values that are in excess of the amounts recognized on the Statement of assets and liabilities. Such risks involve the possibility that there will be no liquid market for the swap, or that a counterparty may default on its obligation or delay

ANNUAL REPORT   |   JOHN HANCOCK FINANCIAL OPPORTUNITIES FUND       23

payment under the swap terms. The counterparty may disagree or contest the terms of the swap. Market risks may also accompany the swap, including interest rate risk. The fund may also suffer losses if it is unable to terminate or assign outstanding swaps or reduce its exposure through offsetting transactions.

During the year ended December 31, 2016, the fund used interest rate swaps to manage against anticipated interest rate changes. The following table summarizes the interest rate swap contracts held as of December 31, 2016:

Counterparty	USD notional amount	Payments made by fund	Payments received by fund	Maturity date	Market value
Centrally Cleared Swaps
	$5,000,000	Fixed 1.2945%	3-Month LIBOR (a)	Aug 2019	$23,379
	10,000,000	Fixed 1.4265%	3-Month LIBOR (a)	Aug 2019	7,447
	5,000,000	Fixed 1.5940%	3-Month LIBOR (a)	Dec 2020	45,004
	5,000,000	Fixed 1.7895%	3-Month LIBOR (a)	Aug 2022	45,642
Total	$25,000,000				$121,472

^(a) At 12-31-16, 3-Month LIBOR was 0.99789%

No interest rate swap positions were entered into or closed during the year ended December 31, 2016.

Note 4 — Guarantees and indemnifications

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

Note 5 — Fees and transactions with affiliates

John Hancock Advisers, LLC (the Advisor) serves as investment advisor for the fund. The Advisor is an indirect, wholly owned subsidiary of Manulife Financial Corporation (MFC).

ANNUAL REPORT   |   JOHN HANCOCK FINANCIAL OPPORTUNITIES FUND       24

Management fee. The fund has an investment advisory 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) 1.15% of the first $500 million of the fund's average daily gross assets, including the assets attributed to the Liquidity Agreement (see Note 8) (collectively, gross managed assets), and (b) 1.00% of the fund's average daily gross managed assets in excess of $500 million. The Advisor has a subadvisory agreement with John Hancock Asset Management a division of Manulife Asset 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 December 31, 2016, this waiver amounted to 0.01% of the fund's average gross managed assets. This arrangement may be amended or terminated at any time by the Advisor upon notice to the fund and with the approval of the Board of Trustees.

The expense reductions described above amounted to $44,746 for the year ended December 31, 2016.

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 December 31, 2016 were equivalent to a net annual effective rate of 1.12% of the fund's average daily gross managed assets.

Administrative services. The fund has an administration agreement with the Advisor under which the Advisor provides certain administrative services to the fund and oversees operational activities of the fund. The compensation for the period was at an annual rate of 0.25% of the average weekly gross managed assets of the fund. The Advisor has agreed to limit the administrative services fee to 0.10% of the fund's average weekly gross assets. Accordingly, the expense reductions related to administrative services fees amounted to $904,557 for the year ended December 31, 2016. The Advisor reserves the right to terminate this limitation in the future with the Trustees' approval.

Trustee expenses. The fund compensates each Trustee who is not an employee of the Advisor or its affiliates. These Trustees receive from the fund and the other John Hancock closed-end funds an annual retainer. In addition, Trustee out-of-pocket expenses are allocated to each fund based on its net assets relative to other funds within the John Hancock group of funds complex.

Note 6 — Fund share transactions

In May 2009, the Board of Trustees approved a share repurchase plan, which was subsequently reviewed and approved by the Board of Trustees each year in December. Under the current share repurchase plan, the fund may purchase in the open market up to 10% of its outstanding common shares as of December 31, 2016. The current share repurchase plan will remain in effect between January 1, 2017 and December 31, 2017. During the year ended December 31, 2016, the fund repurchased 0.05% of shares outstanding. There was no activity under the share repurchase plan during the two-month period ended December 31, 2015 and year ended October 31, 2015. The weighted average discount per share on the repurchases amounted to 8.27% for the year ended December 31, 2016. Shares repurchased and corresponding dollar amounts are included in the Statements of changes in net assets. The antidilutive impact of these share repurchases is included on the Financial highlights.

Note 7 — Leverage risk

The fund utilizes a Liquidity Agreement to increase its assets available for investment. When the fund leverages its assets, common shareholders bear the fees associated with the Liquidity Agreement 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 common shares, including:

ANNUAL REPORT   |   JOHN HANCOCK FINANCIAL OPPORTUNITIES FUND       25

• the likelihood of greater volatility of NAV and market price of common shares;

• fluctuations in the interest rate paid for the use of the Liquidity Agreement;

• 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 Liquidity Agreement 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 8 — Liquidity agreement

The fund has entered into a Liquidity Agreement (LA) with State Street Bank & Trust Company (SSB) that allows it to borrow up to $125.0 million (maximum facility amount) and includes a securities lending provision. The amounts outstanding at December 31, 2016 are shown in the Statement of assets and liabilities as 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 may make these assets available for securities lending transactions. Under the terms of the LA, the fund may enter into securities lending transactions initiated by SSB, acting as the fund's authorized securities lending agent. All securities lent through SSB are required to be secured with cash collateral received from the securities lending counterparty in amounts at least equal to 100% of the initial market value of the securities lent. Cash collateral received by SSB, in its role as securities lending agent for the fund is credited against the amounts drawn under the LA. Any amounts credited against the LA are considered leverage and would be subject to various limitations in the LA and/or the 1940 Act. Upon return of loaned securities, SSB will return collateral to the securities lending counterparty and will cause amounts drawn under the LA to increase by the amount of collateral returned. Amounts paid by securities lending counterparties for loaned securities are retained by SSB.

In the event of a securities lending counterparty default, SSB indemnifies the fund for certain losses that may arise in connection with the default. SSB uses the collateral received from the securities lending counterparty to purchase replacement securities of the same issue, type, class and series of the loaned securities. If the value of the collateral is less than the purchase cost of the replacement securities, SSB is responsible for satisfying the shortfall but only to the extent that the shortfall is not due to any decrease in the value of the collateral. Although the risk of the loss of the securities lent is mitigated by receiving collateral from the securities lending counterparty and through SSB indemnification, the fund could experience a delay in recovering securities or could experience a lower than expected return if the securities lending 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 0.60%, and is payable monthly on the collective balance of the drawdowns outstanding and the securities lending activities of the fund. As of December 31, 2016, the fund had a collective balance of $110,000,000 at an interest rate of 1.37%, which is reflected in the LA payable on the Statement of assets and liabilities. During the year ended December 31, 2016, the average balance of the LA and the effective average interest rate were $110,000,000 and 1.12%, respectively.

ANNUAL REPORT   |   JOHN HANCOCK FINANCIAL OPPORTUNITIES FUND       26

The fund may terminate the LA with 60 days' notice. If certain asset coverage and collateral requirements, minimum net assets or other covenants are not met, the LA could be deemed in default and result in termination. Absent a default or facility termination event, SSB is required to provide the fund with 360 days' notice prior to terminating the LA.

Note 9 — Purchase and sale of securities

Purchases and sales of securities, other than short-term investments, amounted to $66,938,625 and $86,242,346, respectively, for the year ended December 31, 2016.

Note 10 — Industry or sector risk

The fund generally invests a large percentage of its assets in one or more particular industries or sectors of the economy. If a large percentage of the fund's assets are economically tied to a single or small number of industries or sectors of the economy, the fund will be less diversified than a more broadly diversified fund, and it may cause the fund to underperform if that industry or sector underperforms. In addition, focusing on a particular industry or sector may make the fund's NAV more volatile. Further, a fund that invests in particular industries or sectors is particularly susceptible to the impact of market, economic, regulatory and other factors affecting those industries or sectors. Financial services companies can be hurt by economic declines, changes in interest rates regulatory and market impacts.

Note 11 — Transactions in securities of affiliated issuers

Affiliated issuers, as defined by the 1940 Act, are those in which the fund's holdings of an issuer represent 5% or more of the outstanding voting securities of the issuer. A summary of the fund's transactions in the securities of these issuers during the year ended December 31, 2016, is set forth below:

Affiliate			Beginning share amount	Ending share amount	Realized gain (loss)	Dividend income	Ending value
First Colebrook Bancorp, Inc.
	Purchased: 48,750	Sold: none	—	48,750	—	$6,094	$1,053,000
HCSB Financial Corp.
	Purchased: 22,238,470	Sold: none	—	22,238,470	—	—	$2,436,024

Note 12 — New rule issuance

In October 2016, the SEC issued Final Rule Release No. 33-10231, Investment Company Reporting Modernization (the Release). The Release calls for the adoption of new rules and forms as well as amendments to its rules and forms to modernize the reporting and disclosure of information by registered investment companies. The SEC is adopting amendments to Regulation S-X, which will require standardized, enhanced disclosure about derivatives in investment company financial statements, as well as other amendments. Management is in the process of reviewing the impact to the financial statements.

AUDITOR'S REPORT

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders of John Hancock Financial Opportunities Fund:

In our opinion, the accompanying statement of assets and liabilities, including the fund's investments, and the related statements of operations, of changes in net assets, and of cash flows and the financial highlights present fairly, in all material respects, the financial position of the John Hancock Financial Opportunities Fund (the "Fund") as of December 31, 2016, the results of its operations and its cash flows for the year then ended, and the changes in its net assets and the financial highlights for the periods presented, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities as of December 31, 2016 by correspondence with the custodian and brokers, and the application of alternative auditing procedures where securities purchased confirmations had not been received, provide a reasonable basis for our opinion.

Investment objective and policy

The fund is a closed-end, diversified management investment company, shares of which were initially offered to the public in August 1994. The fund's investment objective is to provide a high level of total return consisting of long-term capital appreciation and current income. The fund utilizes a credit facility agreement to increase its assets available for investments.

Under normal circumstances, the fund will invest at least 80% of its net assets plus borrowings for investment purposes in equity securities of U.S. and foreign financial services companies of any size. These companies may include, but are not limited to, banks, thrifts, finance companies, brokerage and advisory firms, real estate-related firms, insurance companies and financial holding companies. The fund will notify shareholders at least 60 days prior to any change in this 80% policy.

Declaration of Trust

Effective January 22, 2016, the Board of Trustees of the fund amended and restated in its entirety the Agreement and Declaration of Trust of the fund (the "Declaration of Trust"). The amendments to the Declaration of Trust include, among other changes, provisions that: (i) clarify certain duties, responsibilities, and powers of the Trustees; (ii) clarify that, other than as provided under federal securities laws, the shareholders may only bring actions involving the Trust derivatively; (iii) provide that any action brought by a shareholder related to the fund will be brought in Massachusetts state or federal court, and that, if a claim is brought in a different jurisdiction and subsequently changed to a Massachusetts venue, the shareholder will be required to reimburse the fund for expenses related to changing venue; and (iv) clarify that shareholders are not intended to be third-party beneficiaries of fund contracts. The foregoing description of the Declaration of Trust is qualified in its entirety by the full text of the Declaration of Trust, effective as of January 22, 2016, which is available by writing to the Secretary of the fund at 601 Congress Street, 11th Floor, Boston, Massachusetts 02210.

Dividends and distributions

During the year ended December 31, 2016, distributions from net investment income totaling $0.4054 per share and from realized gains totaling $1.0750 per share were paid to shareholders. The dates of payments and the amounts per share were as follows:

Payment date	Distributions
March 31, 2016	$0.3701
June 30, 2016	0.3701
September 30, 2016	0.3701
December 30, 2016	0.3701
Total	$1.4804

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.

ANNUAL REPORT   |   JOHN HANCOCK FINANCIAL OPPORTUNITIES FUND       30

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.

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, which is three 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.

Effective November 1, 2013, the Plan was revised to provide that Computershare Trust Company, N.A. no longer provides mail loss insurance coverage when shareholders mail their certificates to the fund's administrator.

All correspondence or requests for additional information about the Plan should be directed to Computershare Trust Company, N.A., at the address stated below, or by calling 800-852-0218, 201-680-6578 (For International Telephone Inquiries) and 800-952-9245 (For the Hearing Impaired (TDD)).

The policies and procedures require that any audit-related and non-audit service provided by the Auditor and any non-audit service provided by the Auditor to a fund service

provider that relates directly to the operations and financial reporting of a fund are subject to approval by the Audit Committee before such service is provided. Audit-related services provided by the Auditor that are expected to exceed $25,000 per instance/per fund are subject to specific pre-approval by the Audit Committee. Tax services provided by the Auditor that are expected to exceed $30,000 per instance/per fund are subject to specific pre-approval by the Audit Committee.

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

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

Audit-Related Fees, Tax Fees and All Other Fees:

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

(f) According to the registrant’s principal accountant, for the fiscal year ended December 31, 2016, the percentage of hours spent on the audit of the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons who were not full-time, permanent employees of principal accountant was less than 50%.

(g) The aggregate non-audit fees billed by the registrant's accountant(s) for services rendered to the registrant and rendered to the registrant's control affiliates for each of the last two fiscal years of the registrant were $4,628,108 for the fiscal period ended December 31, 2016 and $7,126,811 for the fiscal year ended December 31, 2015.

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