S-10

the amount of $25,000 per share of Series F Preferred Stock (equivalent to $25 per Depositary Share), plus any declared and unpaid dividends, without accumulation of any undeclared dividends. Distributions will be madepro rata as to the Series F Preferred Stock and any parity stock and only to the extent of MetLife, Inc.’s assets, if any, that are available after satisfaction of all liabilities to creditors.See “Description of the Series F Preferred Stock — Liquidation Rights.”

Voting Rights Holders of the Series F Preferred Stock will have no voting rights, except with respect to certain fundamental changes in the terms of the Series F Preferred Stock, in the case of certain dividendnon-payments and as otherwise required by applicable law.See “Description of the Series F Preferred Stock — Voting Rights.” Holders of Depositary Shares must act through the Depositary to exercise any voting rights.See “Description of the Depositary Shares — Voting of the Depositary Shares.”

Maturity The Series F Preferred Stock does not have any maturity date, and MetLife, Inc. is not required to redeem the Series F Preferred Stock. Accordingly, all shares of the Series F Preferred Stock and, in turn, the Depositary Shares will remain outstanding indefinitely, unless and until MetLife, Inc. decides to redeem them.

Preemptive Rights Holders of the Series F Preferred Stock will have no preemptive rights.

Certain Material U.S. Federal Income Tax Consequences If you are a noncorporate U.S. holder of Depositary Shares, dividends paid to you will be taxable to you at a maximum rate of 20%, subject to certain requirements described herein, plus all or a portion of such dividends may also be subject to a 3.8% tax imposed on “net investment income.” If you are taxable as a corporation, except as described herein under “Certain Material U.S. Federal Income Tax Consequences — U.S. Holders — Distributions on Series F Preferred Stock,” dividends generally will be eligible for the 50% dividends-received deduction. If you are anon-U.S. holder of Depositary Shares, dividends paid to you are subject to withholding tax at a 30% rate or at a lower rate if you are eligible for the benefits of an income tax treaty that provides for a lower rate.

S-12

RISK FACTORS

Investing in the Depositary Shares and the underlying Series F Preferred Stock involves a high degree of risk. In addition to the other information contained in this prospectus supplement, the accompanying prospectus and the information incorporated by reference herein and therein, you should consider carefully the following factors relating to MetLife, Inc., the Depositary Shares and the Series F Preferred Stock before making an investment in the Depositary Shares and the underlying Series F Preferred Stock offered hereby. In addition to the risk factors set forth below, please read the information included or incorporated by reference under “Risk Factors” in the accompanying prospectus and the 2018 Form10-K. If any of the following risks or those incorporated by reference actually occur, our business, results of operations, financial condition, cash flows or prospects could be materially adversely affected, which in turn could adversely affect the market for or trading price of the Depositary Shares. As a result, you may lose all or part of your original investment. The risks discussed below also include forward-looking statements, and our actual results may differ materially from those expressed or implied in these forward-looking statements.

Risks Relating to the Depositary Shares

General Market Conditions and Unpredictable Factors Could Adversely Affect Market Prices for the Depositary Shares.

There can be no assurance about the market prices for the Depositary Shares. Several factors, many of which are beyond MetLife, Inc.’s control, will influence the market value of the Depositary Shares. Factors that might influence the market value of the Depositary Shares include:

• whether dividends have been declared and are likely to be declared on the Series F Preferred Stock from time to time;

• MetLife, Inc.’s creditworthiness;

• the market for similar securities;

• the number of holders;

• prevailing interest rates;

• additional issuances by MetLife, Inc. of other classes of preferred stock; and

• economic, financial, geopolitical, regulatory or judicial events that affect MetLife, Inc. or the financial markets generally.

Accordingly, if you purchase Depositary Shares, whether in this offering or in the secondary market, the Depositary Shares may trade at a discount to the price that you paid for them.

The Shares of Series F Preferred Stock Are Equity and Are Subordinate to MetLife, Inc.’s Existing and Future Indebtedness.

The shares of Series F Preferred Stock are equity interests in MetLife, Inc. and do not constitute indebtedness. As such, the Series F Preferred Stock will rank junior to all indebtedness and othernon-equity claims on MetLife, Inc. with respect to assets available to satisfy claims on MetLife, Inc., including in a liquidation of MetLife, Inc. As of September 30, 2019, MetLife, Inc.’s total indebtedness was approximately $16.8 billion. MetLife, Inc.’s existing and future indebtedness may restrict payments of dividends on the Series F Preferred Stock. For example, under the terms of its outstanding 6.400%Fixed-to-Floating Rate Junior Subordinated Debentures due 2066, the 7.875%Fixed-to-Floating Rate Exchangeable Surplus Trust Securities of MetLife Capital Trust IV, the 9.250%Fixed-to-Floating Rate Junior Subordinated Debentures due 2068 and the 10.750%Fixed-to-Floating Rate Junior Subordinated Debentures due 2069, MetLife, Inc. is prohibited from declaring or paying any dividends or distributions on its capital stock, including the Series F Preferred Stock, or

S-13

redeeming, purchasing, acquiring, or making a liquidation payment on any shares of its capital stock, if certain financial and capital tests are not met under the indenture governing those securities or at any time MetLife, Inc. is deferring interest on those securities. Additionally, unlike indebtedness, where principal and interest would customarily be payable on specified due dates, in the case of preferred stock like the Series F Preferred Stock (1) dividends are payable only if declared by MetLife, Inc.’s board of directors (or a duly authorized committee of the board) and (2) dividends and any redemption price, if applicable, may be paid by MetLife, Inc., as a corporation, only out of lawfully available funds.

The Depositary Shares Are Fractional Interests in the Shares of the Series F Preferred Stock.

MetLife, Inc. is issuing fractional interests in shares of the Series F Preferred Stock in the form of Depositary Shares. Accordingly, the Depositary will rely on the payments it receives on the Series F Preferred Stock to fund all payments on the Depositary Shares. You should carefully review the information in the accompanying prospectus and in this prospectus supplement regarding both of these securities.

Your Economic Interests in the Underlying Series F Preferred Stock Represented by the Depositary Shares Could be Adversely Affected by the Issuance of Additional Preferred Shares, Including Additional Shares of Series F Preferred Stock, and by Other Transactions.

The issuance of additional preferred shares on parity with or senior to the Series F Preferred Stock would adversely affect the economic interests of the holders of the Series F Preferred Stock and the Depositary Shares, and any issuance of preferred shares senior to the Series F Preferred Stock or of additional indebtedness could affect MetLife, Inc.’s ability to pay dividends on, redeem or pay the liquidation preference on the Series F Preferred Stock in the event of MetLife, Inc.’s liquidation, dissolution orwinding-up.

Holders May Not Receive Dividends on the Series F Preferred Stock.

Dividends on the Series F Preferred Stock are discretionary andnon-cumulative. Consequently, if MetLife, Inc.’s board of directors (or a duly authorized committee of the board) does not authorize and declare a dividend for any dividend period, holders of the Series F Preferred Stock and, in turn, the Depositary Shares would not be entitled to receive any such dividend, and such unpaid dividend will cease to accrue and be payable. MetLife, Inc. will have no obligation to pay dividends accrued for a dividend period after the dividend payment date for such period if MetLife, Inc.’s board of directors (or a duly authorized committee of the board) has not declared such dividend before the related dividend payment date, whether or not dividends are declared for any subsequent dividend period with respect to the Series F Preferred Stock, the Series E Preferred Stock, the Series D Preferred Stock, the Series C Preferred Stock, the Series A Preferred Stock or any other preferred stock MetLife, Inc. may issue.

In addition, if MetLife, Inc. fails to comply, or if and to the extent such act would cause MetLife, Inc. to fail to comply, with applicable laws, rules and regulations (including, to the extent MetLife, Inc. becomes subject to regulation by a “capital regulator,” any applicable capital adequacy guidelines), MetLife, Inc. may not declare, pay or set aside for payment dividends on the Series F Preferred Stock. As a result, if payment of dividends on the Series F Preferred Stock for any dividend period would cause MetLife, Inc. to fail to comply with any applicable law, rule or regulation, MetLife, Inc. will not declare or pay a dividend for such dividend period.

MetLife, Inc. May Redeem the Series F Preferred Stock on or After March 15, 2025 and at Any Time Prior to March 15, 2025 in the Event of a Rating Agency Event or Regulatory Capital Event.

The Series F Preferred Stock will be a perpetual equity security. This means that it will have no maturity or mandatory redemption date and will not be redeemable at the option of the holders. The Series F Preferred Stock may be redeemed by MetLife, Inc. at its option, (a) in whole but not in part, at any time prior to March 15, 2025, within 90 days after the occurrence of a “rating agency event,” at a redemption price equal to $25,500 per share

S-14

of Series F Preferred Stock (equivalent to $25.50 per Depositary Share), plus an amount equal to any accrued and unpaid dividends per share that have accrued but not been declared and paid for the then-current dividend period to, but excluding, such redemption date and (b)(i) in whole but not in part, at any time prior to March 15, 2025, within 90 days after the occurrence of a “regulatory capital event,” or (ii) in whole or in part, at any time or from time to time on or after March 15, 2025, in each case, at a redemption price equal to $25,000 per share of Series F Preferred Stock (equivalent to $25 per Depositary Share), plus an amount equal to any accrued and unpaid dividends per share that have accrued but not been declared and paid for the then-current dividend period to, but excluding, such redemption date. If the Series F Preferred Stock is treated as “Tier 1 capital” (or a substantially similar concept) under the capital guidelines of MetLife, Inc.’s “capital regulator,” any redemption of the Series F Preferred Stock may be subject to MetLife, Inc.’s receipt of any required prior approval from the “capital regulator” and to the satisfaction of any conditions to MetLife, Inc.’s redemption of the Series F Preferred Stock set forth in those capital guidelines or any other applicable regulations of the “capital regulator.”

Any decision MetLife, Inc. may make at any time to redeem of the Series F Preferred Stock will depend upon, among other things, MetLife, Inc.’s evaluation of its capital position, the composition of its stockholders’ equity and general market conditions at that time. Events that would constitute a “rating agency event” or a “regulatory capital event” could occur at any time and could result in the Series F Preferred Stock being redeemed earlier than would otherwise be the case. If MetLife, Inc. chooses to redeem the Series F Preferred Stock, you may not be able to reinvest the redemption proceeds in a comparable security at an effective dividend rate or interest as high as the dividend payable on the Series F Preferred Stock.

If MetLife, Inc. is Not Paying Full Dividends on Any Outstanding Parity Stock, MetLife, Inc. Will Not Be Able to Pay Full Dividends on the Series F Preferred Stock.

When dividends are not paid in full on the shares of Series F Preferred Stock or any shares of parity stock for a dividend period, all dividends declared with respect to shares of Series F Preferred Stock and all parity stock for such dividend period shall be declared pro rata so that the respective amounts of such dividends declared bear the same ratio to each other as all accrued but unpaid dividends per share on the shares of Series F Preferred Stock for such dividend period and all parity stock for such dividend period bear to each other. Therefore, if MetLife, Inc. is not paying full dividends on any outstanding parity stock, MetLife, Inc. will not be able to pay full dividends on the Series F Preferred Stock and, in turn, the Depositary Shares.

MetLife, Inc.’s Ability to Pay Dividends on the Series F Preferred Stock is Dependent Upon Distributions From Its Subsidiaries, But Its Subsidiaries’ Ability to Make Distributions is Limited By Law and Certain Contractual Agreements.

MetLife, Inc. is a holding company whose principal assets are its investments in its subsidiaries. As a holding company, MetLife, Inc. is dependent on dividends, returns of capital and interest income from its subsidiaries to meet its obligations and pay dividends. These subsidiaries are separate legal entities and have no obligation to pay any amounts due under MetLife, Inc.’s obligations or to make any funds available for any dividend payments.

As most recently described in the Third Quarter Form10-Q, MetLife, Inc.’s domestic and international insurance and various other subsidiary companies are subject to regulatory limitations on the payment of dividends and on other transfers of funds to their respective parent entities. For example, the New York Insurance Law places restrictions and limitations on the amount of dividends or other distributions payable by Metropolitan Life Insurance Company, a New York domestic insurance company. Dividends in excess of prescribed limits require the prior insurance regulatory clearance of the New York State Department of Financial Services (the “NYDFS”). The New York Insurance Law permits Metropolitan Life Insurance Company, without prior insurance regulatory clearance, to pay stockholder dividends in any calendar year based on either one of two standards. Under one standard, Metropolitan Life Insurance Company is permitted, without prior insurance regulatory clearance, to pay dividends out of earned surplus (defined as positive “unassigned funds (surplus)”

S-15

excluding 85% of the change in net unrealized capital gains or losses (less capital gains tax), for the immediately preceding calendar year), in an amount up to the greater of: (i) 10% of its surplus to policyholders as of the end of the immediately preceding calendar year, or (ii) its statutory net gain from operations for the immediately preceding calendar year (excluding realized capital gains), not to exceed 30% of its surplus to policyholders as of the end of the immediately preceding calendar year. In addition, under this standard, Metropolitan Life Insurance Company may not, without prior insurance regulatory clearance, pay any dividends in any calendar year immediately following a calendar year for which its net gain from operations, excluding realized capital gains, was negative. Under the second standard, if dividends are paid out of other than earned surplus, Metropolitan Life Insurance Company may, without prior insurance regulatory clearance, pay an amount up to the lesser of: (i) 10% of its surplus to policyholders as of the end of the immediately preceding calendar year, or (ii) its statutory net gain from operations for the immediately preceding calendar year (excluding realized capital gains). In addition, Metropolitan Life Insurance Company will be permitted to pay a dividend in excess of the amounts allowed under both standards only if it files notice of its intention to declare such a dividend and the amount thereof with the Superintendent of the NYDFS and the Superintendent either approves the distribution of the dividend or does not disapprove the dividend within 30 days of its filing. Under the New York Insurance Law, the Superintendent has broad discretion in determining whether the financial condition of a stock life insurance company would support the payment of such dividends to its stockholder.

In addition to regulatory restrictions, the ability of some of MetLife, Inc.’s subsidiaries to make distributions to MetLife, Inc. is limited by contractual agreements. Finally, MetLife, Inc.’s objective to capitalize its insurance subsidiaries in accordance with their ratings targets itself may constrain their payment of dividends. These restrictions on MetLife, Inc.’s subsidiaries may limit or prevent such subsidiaries from making dividend payments to MetLife, Inc. in an amount sufficient to fund MetLife, Inc.’s payment of dividends on the Series F Preferred Stock and, in turn, the Depositary Shares.

The Depositary Shares and the Underlying Series F Preferred Stock May Not Have an Active Trading Market.

The Depositary Shares and the underlying Series F Preferred Stock do not have an established trading market. Although MetLife, Inc. plans to apply to have the Depositary Shares listed on the New York Stock Exchange, there is no guarantee that it will be able to list the Depositary Shares. Even if the Depositary Shares are listed, MetLife, Inc. cannot assure you that an active after-market for the Depositary Shares will develop or be sustained or that holders of the Depositary Shares will be able to sell their Depositary Shares at favorable prices or at all. The difference between bid and ask prices in any secondary market for the Depositary Shares could be substantial. Accordingly, no assurance can be given as to the liquidity of, or trading markets for, the Depositary Shares, and holders of the Depositary Shares (which do not have a maturity date) may be required to bear the financial risks of an investment in the Depositary Shares for an indefinite period of time. MetLife, Inc. does not expect that there will be any separate public trading market for the shares of Series F Preferred Stock except as represented by the Depositary Shares.

The Voting Rights of Holders of the Series F Preferred Stock and, in turn, the Depositary Shares Will Be Limited.

Holders of the Series F Preferred Stock and, in turn, the Depositary Shares have no voting rights with respect to matters that generally require the approval of voting stockholders. The limited voting rights of holders of the Series F Preferred Stock include the right to vote as a class on certain fundamental matters that may affect the preference or special rights of the Series F Preferred Stock, as described under “Description of the Series F Preferred Stock — Voting Rights.” In addition, if dividends on the Series F Preferred Stock have not been declared or paid for the equivalent of six dividend payments, whether or not for consecutive dividend periods, holders of the outstanding Series F Preferred Stock and, in turn, the Depositary Shares, together with holders of any other series of MetLife, Inc.’s preferred stock ranking equal with the Series F Preferred Stock with similar voting rights, including the Series A Preferred Stock, the Series C Preferred Stock, the Series D Preferred Stock

S-16

and the Series E Preferred Stock, will be entitled to vote for the election of two additional directors, subject to the terms and to the limited extent described under “Description of the Series F Preferred Stock — Voting Rights” and “Description of the Depositary Shares — Voting of the Depositary Shares.” Holders of the Depositary Shares must act through the Depositary to exercise any voting rights in respect of the Series F Preferred Stock. Although each Depositary Share is entitled to 1/1,000th of a vote, the Depositary can only vote whole shares of Series F Preferred Stock. While the Depositary will vote the maximum number of whole shares of the Series Preferred Stock in accordance with the instructions it receives, any remaining votes of holders of the Depositary Shares will not be voted.

A Downgrade, Suspension or Withdrawal of, or Change in, the Methodology Used to Determine Any Rating Assigned by a Rating Agency to MetLife, Inc. or Its Securities, Including the Series F Preferred Stock, Could Cause the Liquidity or Trading Price of the Series F Preferred Stock to Decline Significantly.

Real or anticipated changes in the credit ratings assigned to the Depositary Shares, the Series F Preferred Stock or MetLife, Inc.’s credit ratings generally could affect the trading price of the Depositary Shares. Credit ratings are not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any time by the issuing organization in its sole discretion. In addition, credit rating agencies continually review their ratings for the companies that they follow, including us. The credit rating agencies also evaluate the financial services industry as a whole and may change their credit rating for MetLife, Inc. and its securities, including the Depositary Shares and the Series F Preferred Stock, based on their overall view of our industry. A downgrade, withdrawal, or the announcement of a possible downgrade or withdrawal of the ratings assigned to the Depositary Shares and the Series F Preferred Stock, MetLife, Inc. or its other securities, or any perceived decrease in our creditworthiness could cause the trading price of the Depositary Shares to decline significantly.

The rating agencies that currently or may in the future publish a rating for MetLife, Inc., the Depositary Shares or the Series F Preferred Stock may from time to time in the future change the methodologies that they use for analyzing securities with features similar to the Depositary Shares or the Series F Preferred Stock. This may include, for example, changes to the relationship between ratings assigned to an issuer’s senior securities and ratings assigned to securities with features similar to the Depositary Shares or the Series F Preferred Stock, which is sometimes called “notching.” If the rating agencies change their practices for rating these securities in the future, and the ratings of the Depositary Shares or the Series F Preferred Stock are subsequently lowered or “notched” further, the trading price of the Depositary Shares could be negatively affected.

There May Be Future Sales of Preferred Shares or the Depositary Shares, Which May Adversely Affect the Market Price of the Depositary Shares.

MetLife, Inc. is not restricted from issuing additional Series F Preferred Stock or Depositary Shares or securities similar to the Series F Preferred Stock or the Depositary Shares, including any securities that are convertible into or exchangeable for, or that represent the right to receive, Series F Preferred Stock or Depositary Shares. Holders of the Series F Preferred Stock or the Depositary Shares have no preemptive rights that entitle holders to purchase theirpro ratashare of any offering of shares of any class or series. The market price of the Depositary Shares could decline as a result of sales of Series F Preferred Stock or Depositary Shares or of other securities made after this offering or the perception that such sales could occur. Because MetLife, Inc.’s decision to issue securities in any future offering will depend on market conditions and other factors beyond its control, MetLife, Inc. cannot predict or estimate the amount, timing or nature of any future offerings. Thus, holders of the Depositary Shares bear the risk of MetLife, Inc.’s future offerings reducing the market price of the Depositary Shares and diluting their holdings in the Series F Preferred Stock.

DESCRIPTION OF THE SERIES F PREFERRED STOCK

The following description of the particular terms of the Series F Preferred Stock supplements the description of the general terms and provisions of the preferred stock set forth under “Description of Capital Stock — Preferred Stock” beginning on page 18 in the accompanying prospectus. The following summary of the terms and provisions of the Series F Preferred Stock does not purport to be complete and is qualified in its entirety by reference to the pertinent sections of our amended and restated certificate of incorporation, which we have previously filed with the SEC, and the Certificate of Designations creating the Series F Preferred Stock, which will be included as an exhibit to documents that MetLife, Inc. files with the SEC. As used in this section, “we,” “us,” “our” and “MetLife” mean MetLife, Inc. and do not include its subsidiaries.

General

Our authorized capital stock includes 200,000,000 shares of preferred stock, par value $0.01 per share, which includes 10,000,000 shares of our Series A Junior Preferred Shares, 27,600,000 shares of our Series A Preferred Stock, 1,500,000 shares of our Series C Preferred Stock, 500,000 shares of our Series D Preferred Stock and 32,200 shares of our Series E Preferred Stock. No shares of our Series A Junior Preferred Stock have been issued or are outstanding. The shares of Series F Preferred Stock represented by Depositary Shares offered by this prospectus supplement and the accompanying prospectus are part of a single series of authorized preferred stock consisting of 40,000 shares. Depositary Shares representing 40,000 shares of Series F Preferred Stock are being offered hereby. We may from time to time, without notice to or the consent of holders of the Depositary Shares and the underlying Series F Preferred Stock, issue additional Series F Preferred Stock.

The Series F Preferred Stock will rank senior to our junior stock (as defined herein) and equally with each other series of our preferred stock that we have issued or may issue (except for any senior series that may be issued with the requisite consent of the holders of the Series F Preferred Stock), with respect to the payment of dividends and distributions of assets upon liquidation, dissolution orwinding-up. In addition, we will generally be able to pay dividends, any redemption price and distributions upon liquidation, dissolution orwinding-up only out of lawfully available funds for such payment (i.e., after taking account of all indebtedness and othernon-equity claims). The Series F Preferred Stock will be fully paid and nonassessable when issued, which means that holders will have paid their purchase price in full and that we may not ask them to surrender additional funds. Holders of the Series F Preferred Stock will not have preemptive or subscription rights to acquire more stock of MetLife.

The Series F Preferred Stock will not be convertible into, or exchangeable for, shares of any other class or series of stock or other securities of MetLife, Inc. The Series F Preferred Stock has no stated maturity and will not be subject to any sinking fund, retirement fund or purchase fund or other obligation of MetLife to redeem, repurchase or retire the Series F Preferred Stock.

Dividends

Dividends on the Series F Preferred Stock will not be mandatory. Holders of Series F Preferred Stock will be entitled to receive, when, as and if declared by our board of directors (or a duly authorized committee of the board), out of funds legally available for the payment of dividends, under Delaware law,non-cumulative cash dividends that accrue for the relevant dividend period quarterly in arrears on the 15^th day of March, June, September and December of each year, commencing on June 15, 2020. Dividends will accrue from the date of original issue at a fixed rateper annum of 4.75%. If we issue additional shares of Series F Preferred Stock after the original issue date, dividends on such shares may accrue from the original issue date or any other date we specify at the time such additional shares are issued. Dividend payment dates are subject to adjustment for business days.

A dividend period is the period from, and including, a dividend payment date to, but excluding, the next dividend payment date, except that the initial dividend period will commence on, and include, the original issue date of the Series F Preferred Stock and will end on, but exclude, the June 15, 2020 dividend payment date.

S-22

Dividends will be payable to holders of record of the Series F Preferred Stock as they appear on our books on the applicable record date, which shall be the 15^th calendar day before that dividend payment date or such other record date fixed by our board of directors (or a duly authorized committee of the board) that is not more than 60 nor less than 10 days prior to such dividend payment date (each, a “dividend record date”). Dividend record dates will apply regardless of whether a particular dividend record date is a business day.

Dividends payable on the Series F Preferred Stock will be calculated on the basis of a360-day year consisting of twelve30-day months. If any dividend payment date is a day that is not a business day (as defined below), then the dividend with respect to that dividend payment date will instead be paid on the immediately succeeding business day, without interest or other payment in respect of such delayed payment. “Business day” means any day other than a day on which federal or state banking institutions in the Borough of Manhattan, The City of New York, are authorized or obligated by law, executive order or regulation to close.

Dividends on the Series F Preferred Stock will not be cumulative. Accordingly, if MetLife, Inc.’s board of directors (or a duly authorized committee of the board), does not declare a dividend on the Series F Preferred Stock payable in respect of any dividend period before the related dividend payment date, such dividend will not accrue, we will have no obligation to pay a dividend for that dividend period on the dividend payment date or at any future time, whether or not dividends on the Series F Preferred Stock are declared for any future dividend period and no interest, or sum of money in lieu of interest, will be payable in respect of any dividend not so declared.

So long as any Series F Preferred Stock remains outstanding for any dividend period, unless the full dividends for the latest completed dividend period on all outstanding Series F Preferred Stock and parity stock (including the Series A Preferred Stock, the Series C Preferred Stock, the Series D Preferred Stock and the Series E Preferred Stock) have been declared and paid (or declared and a sum sufficient for the payment thereof has been set aside):

• no dividend shall be paid or declared on our common stock or any other shares of our junior stock (as defined below) (other than a dividend payable solely in shares of junior stock); and

• no common stock or other junior stock shall be purchased, redeemed or otherwise acquired for consideration by us, directly or indirectly (other than as a result of a reclassification of junior stock for or into other junior stock, or the exchange or conversion of one share of junior stock for or into another share of junior stock and other than through the use of the proceeds of a substantially contemporaneous sale of junior stock) during a dividend period.

As used in this prospectus supplement, “junior stock” means our common stock, the Series A Junior Preferred Stock and any other class or series of stock of MetLife, Inc. that ranks junior to the Series F Preferred Stock either as to the payment of dividends (whether such dividends are cumulative ornon-cumulative) and/or as to the distribution of assets upon any liquidation, dissolution orwinding-up of MetLife, Inc.

When dividends are not paid (or declared and a sum sufficient for payment thereof set aside) in full on any dividend payment date (or, in the case of parity stock having dividend payment dates different from the dividend payment dates pertaining to the Series F Preferred Stock, on a dividend payment date falling within the related dividend period for the Series F Preferred Stock) upon the Series F Preferred Stock or any shares of parity stock, all dividends declared on the Series F Preferred Stock and all such parity stock and payable on such dividend payment date (or, in the case of parity stock having dividend payment dates different from the dividend payment dates pertaining to the Series F Preferred Stock, on a dividend payment date falling within the related dividend period for the Series F Preferred Stock) shall be declaredpro rataso that the respective amounts of such dividends shall bear the same ratio to each other as all accrued but unpaid dividends per Series F Preferred Stock and all parity stock payable on such dividend payment date (or, in the case of parity stock having dividend payment dates different from the dividend payment dates pertaining to the Series F Preferred Stock, on a dividend payment date falling within the related dividend period for the Series F Preferred Stock) bear to each other.

S-23

As used in this prospectus supplement, “parity stock” means the Series A Preferred Stock, the Series C Preferred Stock, the Series D Preferred Stock, the Series E Preferred Stock and any other class or series of stock of MetLife, Inc. that ranks equally with the Series F Preferred Stock in the payment of dividends (whether such dividends are cumulative ornon-cumulative) and in the distribution of assets on any liquidation, dissolution orwinding-up of MetLife, Inc.

Subject to the foregoing, dividends (payable in cash, stock or otherwise) as may be determined by our board of directors (or a duly authorized committee of the board) may be declared and paid on our common stock and any other junior stock from time to time out of any funds legally available for such payment, and the Series F Preferred Stock shall not be entitled to participate in any such dividend.

Dividends on the Series F Preferred Stock will not be declared, paid or set aside for payment if we fail to comply, or if such act would cause us to fail to comply, with applicable laws, rules and regulations (including, to the extent MetLife, Inc. becomes subject to regulation by a “capital regulator,” any applicable capital adequacy guidelines).

Liquidation Rights

Upon any voluntary or involuntary liquidation, dissolution orwinding-up of MetLife, Inc., holders of the Series F Preferred Stock and any parity stock are entitled to receive out of assets of MetLife, Inc. available for distribution to stockholders, after satisfaction of liabilities to creditors, if any, before any distribution of assets is made to holders of common stock and any other junior stock, a liquidating distribution in the amount of $25,000 per share of Series F Preferred Stock (equivalent to $25 per Depositary Share), plus declared and unpaid dividends, without accumulation of any undeclared dividends. Holders of the Series F Preferred Stock will not be entitled to any other amounts from us after they have received their full liquidation preference.

In any such distribution, if the assets of MetLife, Inc. are not sufficient to pay the liquidation preferences in full to all holders of the Series F Preferred Stock and all holders of any parity stock, the amounts paid to the holders of Series F Preferred Stock and to the holders of any parity stock will be paidpro rata in accordance with the respective aggregate liquidation preferences of those holders. In any such distribution, the “liquidation preference” of any holder of preferred stock means the amount payable to such holder in such distribution, including any declared but unpaid dividends (and any unpaid, accrued cumulative dividends in the case of any holder of stock (other than Series F Preferred Stock) on which dividends accrue on a cumulative basis). If the liquidation preference has been paid in full to all holders of the Series F Preferred Stock and any holders of parity stock, the holders of our other stock shall be entitled to receive all remaining assets of MetLife, Inc. according to their respective rights and preferences.

For purposes of this section, the merger or consolidation of MetLife, Inc. with any other entity, including a merger or consolidation in which the holders of the Series F Preferred Stock receive cash, securities or other property for their shares, or the sale, lease or exchange of all or substantially all of the assets of MetLife, Inc., for cash, securities or other property shall not constitute a liquidation, dissolution orwinding-up of MetLife, Inc.

Optional Redemption

The Series F Preferred Stock is not subject to any mandatory redemption, sinking fund, retirement fund, purchase fund or other similar provisions. We may redeem the Series F Preferred Stock at our option:

• in whole but not in part, at any time prior to March 15, 2025, within 90 days after the occurrence of a “rating agency event,” at a redemption price equal to $25,500 per share of Series F Preferred Stock (equivalent to $25.50 per Depositary Share), plus (except as provided below) an amount equal to any dividends per share that have accrued but not been declared and paid for the then-current dividend period to, but excluding, the redemption date, or

S-24

• (i) in whole but not in part, at any time prior to March 15, 2025, within 90 days after the occurrence of a “regulatory capital event,” or (ii) in whole or in part, at any time or from time to time on or after March 15, 2025, in each case, at a redemption price equal to $25,000 per share of Series F Preferred Stock (equivalent to $25 per Depositary Share), plus (except as provided below) an amount equal to any dividends per share that have accrued but not been declared and paid for the then-current dividend period to, but excluding, the redemption date.

Any declared but unpaid dividends payable on a redemption date that occurs subsequent to the dividend record date for a dividend period will not constitute a part of or be paid to the holder entitled to receive the redemption price on the redemption date, but rather will be paid to the holder of record of the redeemed shares on the dividend record date relating to the dividend payment date.

Holders of the shares of Series F Preferred Stock will not have the right to require the redemption or repurchase of the Series F Preferred Stock.

“Rating agency event” means that any nationally recognized statistical rating organization as defined in Section 3(a)(62) of the Exchange Act, that then publishes a rating for us (a “rating agency”) amends, clarifies or changes the criteria it uses to assign equity credit to securities such as the Series F Preferred Stock, which amendment, clarification or change results in:

• the shortening of the length of time the Series F Preferred Stock is assigned a particular level of equity credit by that rating agency as compared to the length of time they would have been assigned that level of equity credit by that rating agency or its predecessor on the initial issuance of the Series F Preferred Stock; or

• the lowering of the equity credit (including up to a lesser amount) assigned to the Series F Preferred Stock by that rating agency as compared to the equity credit assigned by that rating agency or its predecessor on the initial issuance of the Series F Preferred Stock.

“Regulatory capital event” means that we provide notice to the holders that we have made a good faith determination that, as a result of (i) any amendment to, or change in, the laws, rules, regulations or regulatory standards of the United States or any political subdivision of or in the United States or any governmental agency, instrumentality or standard-setting organization as may then have group-wide oversight of MetLife, Inc.’s regulatory capital (including, for the avoidance of doubt, our “capital regulator”) that is enacted or becomes effective after the initial issuance of the Series F Preferred Stock; (ii) any proposed amendment to, or change in, those laws, rules, regulations or regulatory standards that is announced or becomes effective after the initial issuance of the Series F Preferred Stock; or (iii) any official administrative decision or judicial decision or administrative action or other official pronouncement interpreting or applying those laws, rules, regulations or regulatory standards that is announced after the initial issuance of the Series F Preferred Stock, there is more than an insubstantial risk that the full liquidation preference of the Series F Preferred Stock outstanding from time to time would not qualify as “Tier 1 Capital” (or a substantially similar concept) for purposes of the capital adequacy rules or regulatory standards of any “capital regulator” to which we are or will be subject;provided that the proposal or adoption of any criterion that is substantially the same as the corresponding criterion in the capital adequacy rules of the Federal Reserve Board applicable to bank holding companies as of the initial issuance of the Series F Preferred Stock will not constitute a regulatory capital event.

“Capital regulator” means any governmental agency, instrumentality or standard-setting organization, including, but not limited to, the Federal Reserve Board, the FIO, the NAIC or any state insurance regulator, as may then have group-wide oversight of MetLife, Inc.’s regulatory capital.

If the Series F Preferred Stock is to be redeemed, the notice of redemption shall be given by first class mail to the holders of record of the Series F Preferred Stock to be redeemed, mailed not less than 30 days nor more than 90 days prior to the date fixed for redemption thereof (provided that, if the Series F Preferred Stock is held

S-25

in book-entry form through DTC we may give such notice in any manner permitted by DTC). Each notice of redemption will include a statement setting forth:

• the redemption date;

• the number of shares of Series F Preferred Stock to be redeemed and, if less than all the shares of Series F Preferred Stock held by such holder are to be redeemed, the number of such shares of Series F Preferred Stock to be redeemed from such holder;

• the redemption price; and

• the place or places where holders may surrender certificates evidencing the Series F Preferred Stock for payment of the redemption price.

If notice of redemption of any Series F Preferred Stock has been given and if the funds necessary for such redemption have been set aside by us for the benefit of the holders of any Series F Preferred Stock so called for redemption, then, from and after the redemption date, dividends will cease to accrue on such Series F Preferred Stock, such Series F Preferred Stock shall no longer be deemed outstanding and all rights of the holders of such Series F Preferred Stock will terminate, except the right to receive the redemption price.

In case of any redemption of only part of the Series F Preferred Stock at the time outstanding, the Series F Preferred Stock to be redeemed shall be selected eitherpro rataor by lot.

If the Series F Preferred Stock is treated as “Tier 1 capital” (or a substantially similar concept) under the capital guidelines of a “capital regulator,” any redemption of the Series F Preferred Stock may be subject to MetLife, Inc.’s receipt of any required prior approval from the “capital regulator” and to the satisfaction of any conditions to MetLife, Inc.’s redemption of the Series F Preferred Stock set forth in those capital guidelines or any other applicable regulations of the “capital regulator.”

Voting Rights

Except as provided below or as otherwise required by applicable law, the holders of the Series F Preferred Stock will have no voting rights.

Whenever dividends on any Series F Preferred Stock shall have not been declared and paid for the equivalent of six or more dividend payments, whether or not for consecutive dividend periods (a “Nonpayment”), the holders of such Series F Preferred Stock, voting together as a single class with holders of any and all other series of voting preferred stock (as defined below) then outstanding, will be entitled to vote for the election of a total of two additional members of our board of directors (the “Preferred Stock Directors”),provided that the election of any such directors shall not cause us to violate the corporate governance requirement of the New York Stock Exchange (or any other exchange on which our securities may be listed) that listed companies must have a majority of independent directors. In that event, the number of directors on our board of directors shall automatically increase by two, and the new directors shall be elected at a special meeting called at the request of the holders of record of at least 20% of the Series F Preferred Stock or of any other series of voting preferred stock (unless such request is received less than 90 days before the date fixed for the next annual or special meeting of the stockholders, in which event such election shall be held at such next annual or special meeting of stockholders), and at each subsequent annual meeting. These voting rights will continue until dividends on the Series F Preferred Stock and any such series of voting preferred stock for at least four consecutive dividend periods following the Nonpayment shall have been fully paid (or declared and a sum sufficient for the payment of such dividends shall have been set aside for payment).

As used in this prospectus supplement, “voting preferred stock” means any other class or series of preferred stock of MetLife, Inc. ranking equally with the Series F Preferred Stock either as to the payment of dividends or the distribution of assets upon liquidation, dissolution orwinding-up and upon which like voting rights have been

S-26

conferred and are exercisable, and includes the Series A Preferred Stock, the Series C Preferred Stock, the Series D Preferred Stock and the Series E Preferred Stock. Whether a plurality, majority or other portion of the Series F Preferred Stock and any other voting preferred stock have been voted in favor of any matter shall be determined by reference to the liquidation amounts of the Series F Preferred Stock voted.

If and when dividends for at least four consecutive dividend periods following a Nonpayment have been paid in full (or declared and a sum sufficient for such payment shall have been set aside), the holders of the Series F Preferred Stock shall be divested of the foregoing voting rights (subject to revesting in the event of each subsequent Nonpayment) and, if such voting rights for all other holders of voting preferred stock have terminated, the term of office of each Preferred Stock Director so elected shall terminate and the number of directors on the board of directors shall automatically decrease by two. In determining whether dividends have been paid for four dividend periods following a Nonpayment, we may take account of any dividend we elect to pay for such a dividend period after the regular dividend date for that period has passed. Any Preferred Stock Director may be removed at any time without cause by the holders of record of a majority of the outstanding Series F Preferred Stock and any other shares of voting preferred stock then outstanding (voting together as a class) when they have the voting rights described above. So long as a Nonpayment shall continue, any vacancy in the office of a Preferred Stock Director (other than prior to the initial election after a Nonpayment) may be filled by the written consent of the Preferred Stock Director remaining in office, or if none remains in office, by a vote of the holders of record of a majority of the outstanding Series F Preferred Stock and any other shares of voting preferred stock then outstanding (voting together as a class) when they have the voting rights described above. The Preferred Stock Directors shall each be entitled to one vote per director on any matter.

So long as any Series F Preferred Stock remains outstanding, we will not, without the affirmative vote or consent of the holders of at leasttwo-thirds of the outstanding Series F Preferred Stock and all other series of voting preferred stock entitled to vote thereon, voting together as a single class, given in person or by proxy, either in writing or at a meeting:

• amend or alter the provisions of MetLife, Inc.’s amended and restated certificate of incorporation or the Certificate of Designations for the Series F Preferred Stock so as to authorize or create, or increase the authorized amount of, any class or series of stock ranking senior to the Series F Preferred Stock with respect to payment of dividends and/or the distribution of assets upon liquidation, dissolution orwinding-up of MetLife, Inc.;

• amend, alter or repeal the provisions of MetLife, Inc.’s amended and restated certificate of incorporation or the Certificate of Designations for the Series F Preferred Stock so as to materially and adversely affect the special rights, preferences, privileges and voting powers of the Series F Preferred Stock, taken as a whole; or

• consummate a binding share exchange or reclassification involving the Series F Preferred Stock or a merger or consolidation of MetLife, Inc. with another entity, unless in each case (i) the Series F Preferred Stock remains outstanding or, in the case of any such merger or consolidation with respect to which we are not the surviving or resulting entity, are converted into or exchanged for preference securities of the surviving or resulting entity or its ultimate parent, and (ii) such Series F Preferred Stock remaining outstanding or such preference securities, as the case may be, have such rights, preferences, privileges and voting powers, taken as a whole, as are not materially less favorable to the holders thereof than the rights, preferences, privileges and voting powers of the Series F Preferred Stock immediately prior to such consummation, taken as a whole;

provided, however, that any increase in the amount of the authorized or issued Series F Preferred Stock or authorized preferred stock or the creation and issuance, or an increase in the authorized or issued amount, of other series of preferred stock ranking equally with and/or junior to the Series F Preferred Stock with respect to the payment of dividends (whether such dividends are cumulative ornon-cumulative) and/or the distribution of assets upon liquidation, dissolution orwinding-up of MetLife, Inc. will not be deemed to materially and adversely affect the special rights, preferences, privileges or voting powers of the Series F Preferred Stock.

S-27

If an amendment, alteration, repeal, share exchange, reclassification, merger or consolidation described above would materially and adversely affect one or more but not all series of voting preferred stock (including the Series F Preferred Stock for this purpose), then only the series materially and adversely affected and entitled to vote shall vote as a class in lieu of all such series of preferred stock.

Without the consent of the holders of the Series F Preferred Stock, so long as such action does not adversely affect the special rights, preferences, privileges and voting powers of the Series F Preferred Stock, taken as a whole, we may amend, alter, supplement or repeal any terms of the Series F Preferred Stock:

• to cure any ambiguity, or to cure, correct or supplement any provision contained in the Certificate of Designations for the Series F Preferred Stock that may be defective or inconsistent; or

• to make any provision with respect to matters or questions arising with respect to the Series F Preferred Stock that is not inconsistent with the provisions of the Certificate of Designations.

The foregoing voting provisions will not apply if, at or prior to the time when the act with respect to which such vote would otherwise be required shall be effected, all outstanding Series F Preferred Stock shall have been redeemed or called for redemption upon proper notice and sufficient funds shall have been set aside by us for the benefit of the holders of Series F Preferred Stock to effect such redemption.

Transfer Agent, Registrar and Dividend Disbursing Agent

Computershare Inc. will be the transfer agent, registrar and dividend disbursing agent for the Series F Preferred Stock.

S-28

DESCRIPTION OF THE DEPOSITARY SHARES

In this prospectus supplement, references to “holders” of the Depositary Shares mean those who own the Depositary Shares registered in their own names, on the books that we or the Depositary maintain for this purpose, and not indirect holders who own beneficial interest in the Depositary Shares registered in street name or issue in book-entry form through DTC. As used in this section, “we,” “us,” “our,” and “MetLife” mean MetLife, Inc. and do not include its subsidiaries.

This prospectus supplement summarizes specific terms and provisions of the Depositary Shares relating to our Series F Preferred Stock. As described above under “Description of the Series F Preferred Stock”, we are issuing fractional interests in shares of the Series F Preferred Stock in the form of the Depositary Shares. Each Depositary Share will represent a 1/1,000th interest in a share of the Series F Preferred Stock, and will be evidenced by a depositary receipt. The shares of the Series F Preferred Stock represented by the Depositary Shares will be deposited under a deposit agreement among us, Computershare Inc. and Computershare Trust Company, N.A. collectively as the Depositary, and the holders from time to time of the depositary receipts evidencing the Depositary Shares. Subject to the terms of the deposit agreement, each holder of Depositary Shares will be entitled, through the Depositary, in proportion to the applicable fraction of a share of the Series F Preferred Stock represented by such Depositary Shares, to all the rights and preferences of the Series F Preferred Stock represented thereby (including dividend, voting, redemption and liquidation rights).

Immediately following issuance of the Series F Preferred Stock, we will deposit the Series F Preferred Stock with the Depositary, which will then issue the Depositary Shares to the underwriters. The deposit agreement and the form of depositary receipts will be included as exhibits to a current report on Form8-K filed with the SEC.

Dividends and Other Distributions

The Depositary will distribute any cash dividends or other cash distributions received in respect of the deposited Series F Preferred Stock to the record holders of the Depositary Shares in proportion to the number of the Depositary Shares held by each holder on the relevant record date. The Depositary will distribute any property received by it other than cash to the record holders of the Depositary Shares entitled to those distributions, unless it determines that the distribution cannot be made proportionally among those holders or that it is not feasible to make a distribution. In that event, the Depositary may, with our approval, sell the property and distribute the net proceeds from the sale to the holders of the Depositary Shares in proportion to the number of the Depositary Shares they hold.

Record dates for the payment of dividends and other matters relating to the Depositary Shares will be the same as the corresponding record dates for the Series F Preferred Stock.

The amounts distributed to holders of the Depositary Shares will be reduced by any amounts required to be withheld by the Depositary or by us on account of taxes or other governmental charges.

Redemption of the Depositary Shares

If we redeem the Series F Preferred Stock represented by the Depositary Shares, in whole or in part, a corresponding number of Depositary Shares will be redeemed from the proceeds received by the Depositary resulting from the redemption of the Series F Preferred Stock held by the Depositary. The redemption price per Depositary Share will be equal to 1/1,000th of the redemption price per share payable with respect to the Series F Preferred Stock, plus any declared and unpaid dividends, without accumulation of any undeclared dividends, on the shares of the Series F Preferred Stock. Whenever we redeem shares of the Series F Preferred Stock held by the Depositary, the Depositary will redeem, as of the same redemption date, the number of the Depositary Shares representing shares of the Series F Preferred Stock so redeemed.

S-29

In case of any redemption of less than all of the outstanding Depositary Shares, the Depositary Shares to be redeemed will be selected by the Depositarypro rata, by lot or by such other method in accordance with DTC’s procedures. In any such case, the Depositary will redeem the Depositary Shares only in increments of 1,000 shares and any integral multiple thereof.

The Depositary will mail (or otherwise transmit by an authorized method) notice of redemption to holders of the Depositary Shares not less than 30 and not more than 60 days prior to the date fixed for redemption of the Series F Preferred Stock and the Depositary Shares.

Voting of the Depositary Shares

When the Depositary receives notice of any meeting at which the holders of the Series F Preferred Stock is entitled to vote, the Depositary will mail (or otherwise transmit by an authorized method) the information contained in the notice to the record holders of the Depositary Shares. Each record holder of Depositary Shares on the record date, which will be the same date as the record date for the Series F Preferred Stock, may instruct the Depositary to vote the amount of the Series F Preferred Stock represented by the holder’s Depositary Shares. Although each Depositary Share is entitled to 1/1,000th of a vote, the Depositary can only vote whole shares of Series F Preferred Stock. To the extent possible, the Depositary will vote the amount of the Series F Preferred Stock represented by the Depositary Shares in accordance with the instructions it receives. We will agree to take all reasonable actions that the Depositary determines are necessary to enable the Depositary to vote as instructed. If the Depositary does not receive specific instructions from the holders of any Depositary Shares, it will not vote the amount of the Series F Preferred Stock represented by such Depositary Shares.

Listing

We intend to apply to list the Depositary Shares on the New York Stock Exchange under the symbol “MET PRF”. If the application is approved, we expect trading to begin within 30 days of the initial delivery of the Depositary Shares. We do not expect that there will be any separate public trading market for the shares of Series F Preferred Stock except as represented by the Depositary Shares.

Form of the Depositary Shares

The Depositary Shares will be issued in book-entry form through DTC. The Series F Preferred Stock will be issued in registered form to the Depositary.

Depositary

Computershare Inc. and Computershare Trust Company, N.A. collectively will be the Depositary for the Depositary Shares as of the original issue date. We may terminate any such appointment and may appoint a successor Depositary at any time and from time to time, provided that we will use our best efforts to ensure that there is, at all relevant times when the Series F Preferred Stock is outstanding, a person or entity appointed and serving as such Depositary.

Book-Entry; Delivery and Form

The Depositary Shares will be represented by one or more fully registered global depositary receipts, each of which is referred to in this prospectus supplement as a “Global Security.” Each such Global Security will be deposited with, or on behalf of, DTC and registered in the name of DTC or a nominee thereof. Unless and until it is exchanged in whole or in part for Depositary Shares in definitive form, no Global Security may be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any such nominee to a successor of DTC or a nominee of such successor.

S-30

Except under limited circumstances, Depositary Shares represented by a Global Security will not be exchangeable for, and will not otherwise be issuable as, certificated depositary receipts. Investors may elect to hold interests in the Global Securities through either DTC (in the United States) or through Clearstream or Euroclear, if they are participants in such systems, or indirectly through organizations which are participants in such systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositaries, which in turn will hold such interests in customers’ securities accounts in the depositaries’ names on the books of DTC.

Beneficial interests in the Depositary Shares will be represented through book-entry accounts of financial institutions acting on behalf of Beneficial Owners (as defined below) as Direct and Indirect Participants (as defined below) in DTC. So long as DTC, or its nominee, is a registered owner of a Global Security, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the Depositary Shares represented by such Global Security for all purposes under the instruments governing the rights and obligations of holders of the Depositary Shares. Except as provided below, the actual owners of the Depositary Shares represented by a Global Security (the “Beneficial Owners”) will not be entitled to have the Depositary Shares represented by such Global Security registered in their names, will not receive or be entitled to receive physical delivery of the Depositary Shares in definitive form and will not be considered the owners or holders thereof under the instruments governing the rights and obligations of holders of the Depositary Shares.

Accordingly, each person owning a beneficial interest in a Global Security must rely on the procedures of DTC and, if such person is not a participant of DTC (a “Participant”), on the procedures of the Participant through which such person owns its interest, to exercise any rights of a holder of the Depositary Shares. Under existing industry practices, if any action is requested of, or entitled to be given or taken under the instruments governing the rights and obligations of holders of the Depositary Shares by, holders of the Depositary Shares, DTC would authorize the Participants holding the relevant beneficial interests to give or take such action, and such Participants would authorize Beneficial Owners owning through such Participants to give or take such action or would otherwise act upon the instructions of Beneficial Owners.

The following is based on information furnished by DTC:

DTC will act as securities depositary for the Depositary Shares. The Depositary Shares will be fully registered securities registered in the name of Cede & Co. (DTC’s partnership nominee). One or more Global Securities will initially represent the Depositary Shares and will be deposited with DTC.

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its Participants deposit with DTC. DTC also facilitates the settlement among Participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in Participants’ accounts, thereby eliminating the need for physical movement of securities certificates. Direct Participants of DTC (“Direct Participants”) include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to DTC’s system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). The rules applicable to DTC and its Participants are on file with the SEC.

Purchases of the Depositary Shares under DTC’s system must be made by or through Direct Participants, which will receive a credit for the Depositary Shares on DTC’s records. The ownership interest of each

S-31

Beneficial Owner is in turn to be recorded on the records of Direct Participants and Indirect Participants. Beneficial Owners will not receive written confirmation from DTC of their purchase, but Beneficial Owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct Participants or Indirect Participants through which such Beneficial Owner entered into the transaction. Transfers of ownership interests in the Series F Preferred Stock are to be accomplished by entries made on the books of Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificated depositary receipts representing their ownership interests in the Depositary Shares, except in the limited circumstances that may be provided in the instruments governing the rights and obligations of holders of the Depositary Shares.

To facilitate subsequent transfers, all Depositary Shares deposited with DTC are registered in the name of DTC’s partnership nominee, Cede & Co. The deposit of the Depositary Shares with DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Depositary Shares. DTC’s records reflect only the identity of the Direct Participants to whose accounts such securities are credited, which may or may not be the Beneficial Owners. The Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Neither DTC nor Cede & Co. will consent or vote with respect to the Depositary Shares. Under its usual procedures, DTC mails an Omnibus Proxy to MetLife, Inc. as soon as possible after the applicable record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts securities are credited on the applicable record date (identified in a listing attached to the Omnibus Proxy).

Payments on the Depositary Shares will be made in immediately available funds to DTC. DTC’s practice is to credit Direct Participants’ accounts on the applicable payment date in accordance with their respective holdings shown on DTC’s records unless DTC has reason to believe that it will not receive payment on such date.

Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such Participant and not of DTC, the Transfer Agent or MetLife, Inc., subject to any statutory or regulatory requirements as may be in effect from time to time. Any payment due to DTC on behalf of Beneficial Owners is MetLife, Inc.’s responsibility or the responsibility of the applicable agent, disbursement of such payments to Direct Participants shall be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners shall be the responsibility of Direct Participants and Indirect Participants.

If: (i) DTC notifies MetLife, Inc. that it is unwilling or unable to continue to act as securities depositary for the Depositary Shares and no successor securities depositary has been appointed pursuant to the instruments governing the rights and obligations of holders of the Depositary Shares within 90 days after such notice; (ii) DTC ceases to be a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act when the securities depositary is required to be so registered and so notifies MetLife, Inc., and no successor securities depositary has been appointed pursuant to the instruments governing the rights and obligations of holders of the Depositary Shares within 90 days after such notice; or (iii) the Company in its sole discretion and subject to DTC’s procedures determines that the Depositary Shares shall be exchangeable for Depositary Shares represented by certificated depositary receipts; then (x) certificated depositary receipts may be prepared by MetLife, Inc. and delivered to the Transfer Agent and (y) upon surrender of the Global Securities representing

S-32

the Depositary Shares by DTC (or any successor securities depositary), accompanied by registration instructions, MetLife, Inc. will cause certificated depositary receipts representing the Depositary Shares to be delivered to Beneficial Owners in accordance with the instructions of DTC (or such successor securities depositary).

Clearstream has advised that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participants (“Clearstream Participants”) and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry transfers between their accounts. Clearstream provides Clearstream Participants with, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic securities markets in several countries through established depository and custodial relationships. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector, also known as theCommission de Surveillance du Secteur Financier. Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and other organizations. Clearstream Participants in the U.S. are limited to securities brokers and dealers and banks and may include the underwriters. Indirect access to Clearstream is also available to other institutions such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with Clearstream Participants. Distributions with respect to interests in global securities held through Clearstream will be credited to cash accounts of its customers in accordance with its rules and procedures, to the extent received by the U.S. depositary for Clearstream.

Euroclear has advised that it was created in 1968 to hold securities for its participants and to clear and settle transactions between Euroclear participants (“Euroclear Participants”) through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing, and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank SA/NV under contract with Euroclear plc, a U.K. corporation. Euroclear Participants include banks, including central banks, securities brokers and dealers and other professional financial intermediaries and may include the Underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

Global Clearance and Settlement Procedures

Secondary market trading between the DTC Participants will occur in the ordinary way in accordance with the DTC rules and will be settled in immediately available funds. Secondary market trading between Clearstream Participants and/or Euroclear Participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional Eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC on the one hand, and directly or indirectly through Clearstream Participants or Euroclear Participants, on the other, will be effected in DTC in accordance with the DTC rules on behalf of the relevant European international clearing system by DTC in its capacity as U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to DTC to take action to effect final settlement on its behalf by delivering interests in the Depositary Shares to or receiving interests in the Depositary Shares from DTC, and making or receiving payment in accordance with normal procedures forsame-day funds settlement applicable to DTC. Clearstream Participants and Euroclear Participants may not deliver instructions directly to DTC.

Because of time-zone differences, credits of interests in the Depositary Shares received in Clearstream or Euroclear as a result of a transaction with a DTC Participant will be made during subsequent securities settlement

S-33

processing and will be credited the business day following the DTC settlement date. Such credits or any transactions involving interests in such Depositary Shares settled during such processing will be reported to the relevant Euroclear or Clearstream Participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of interests in the Depositary Shares by or through a Clearstream Participant or a Euroclear Participant to a DTC Participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of the Depositary Shares among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be discontinued at any time.

The information in this section concerning DTC and its book-entry system, Euroclear and Clearstream has been obtained from sources that we believe to be reliable.

CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

This section describes the material U.S. federal income tax consequences of the ownership and disposition of the Depositary Shares representing interests in the Series F Preferred Stock. It applies to you only if you hold your Depositary Shares (and your interests in the underlying Series F Preferred Stock) as capital assets for U.S. federal income tax purposes. For U.S. federal income tax purposes, a holder of Depositary Shares generally will be treated as the beneficial owner of the underlying Series F Preferred Stock represented by the Depositary Shares. The remainder of this discussion assumes that a holder of Depositary Shares will be so treated and, therefore, when the remainder of this discussion refers only to the Series F Preferred Stock, it means both the Series F Preferred Stock and the Depositary Shares representing shares of the Series F Preferred Stock.

This section does not apply to you if you are a member of a class of holders of Series F Preferred Stock subject to special rules, such as:

• a dealer in securities or currencies;

• a trader in securities that elects to use amark-to-market method of accounting for your securities holdings;

• a bank;

• an insurance company;

• a thrift institution;

• a regulated investment company;

• atax-exempt organization;

• a person that purchases or sells the Series F Preferred Stock as part of a wash-sale for tax purposes;

• a person that owns securities that are part of a hedge or that are hedged against currency risks;

• a person that owns securities as part of a straddle, a “constructive sale” or a conversion transaction for tax purposes;

• an entity or arrangement treated as a partnership for U.S. federal income tax purposes;

• a person required under Section 451(b) of the Code (defined below) to conform the timing of income accruals with respect to the Series F Preferred Stock to their financial statements;

• a person whose functional currency for tax purposes is not the U.S. dollar;

• a person eligible for the deduction with respect to “qualified business income;”

• a United States expatriate; or

• the Depositary.

This section is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), its legislative history, existing and proposed regulations under the Code, published rulings and court decisions, all as currently in effect (except as otherwise described herein). These laws and authorities are subject to change, possibly on a retroactive basis. If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds Series F Preferred Stock, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the tax treatment of the partnership. The discussion that follows will not address the tax consequences to the partners of a partnership that owns Series F Preferred Stock. A partner in a partnership holding Series F Preferred Stock should consult its tax advisor with regard to the U.S. tax treatment of an investment in Series F Preferred Stock.

THIS DISCUSSION OF MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES IS NOT INTENDED, AND SHOULD NOT BE CONSTRUED, TO BE TAX OR LEGAL ADVICE TO ANY

S-35

PARTICULAR INVESTOR IN OR HOLDER OF THE SERIES F PREFERRED STOCK. PROSPECTIVE INVESTORS ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS CONCERNING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSIDERATIONS ARISING UNDER THE LAWS OF ANY STATE, LOCAL OR FOREIGN TAXING JURISDICTION OR ANY APPLICABLE TAX TREATIES, AND THE POSSIBLE EFFECT OF CHANGES IN APPLICABLE TAX LAW.

U.S. Holders

This subsection describes the U.S. federal income tax consequences of the ownership and disposition of Series F Preferred Stock by a U.S. Holder. You are a U.S. Holder if you are a beneficial owner of Series F Preferred Stock and you are:

• an individual citizen or resident of the United States;

• a domestic corporation;

• an estate whose income is subject to U.S. federal income tax regardless of its source; or

• a trust if a U.S. court has the authority to exercise primary supervision over the trust’s administration and one or more U.S. persons are authorized to control all substantial decisions of the trust.

If you are not a U.S. Holder, this subsection does not apply to you and you should refer to“— Non-U.S. Holders.”

Distributions on the Series F Preferred Stock

U.S. Holders will be taxed on distributions on the Series F Preferred Stock as dividend income to the extent the distribution is paid out of MetLife, Inc.’s current or accumulated earnings and profits for U.S. federal income tax purposes. If you are a noncorporate U.S. Holder, dividends paid to you will constitute “qualified dividend income” taxable to you at a maximum rate of 20%, provided that you hold your Series F Preferred Stock for more than 60 days during the121-day period beginning 60 days before theex-dividend date or, if the dividend is attributable to a period or periods aggregating over 366 days, provided that you hold your Series F Preferred Stock for more than 90 days during the181-day period beginning 90 days before theex-dividend date. All or a portion of your dividends may be subject to an additional 3.8% tax imposed on “net investment income,” which applies to certain investment income and certain other passive income earned in households with income over $250,000 (married filing jointly or surviving spouse), $125,000 (married filing separately) or $200,000 (single).

Corporate holders of the Series F Preferred Stock may be eligible for the 50% “dividends received deduction” with respect to dividend distributions that are paid on the Series F Preferred Stock,provided certain holding period requirements are satisfied.

With respect to distributions not paid out of MetLife, Inc.’s current or accumulated earnings and profits, you generally will not be taxed on any portion of such distribution if your tax basis in the Series F Preferred Stock is greater than or equal to the amount of the distribution. However, you would be required to reduce your tax basis (but not below zero) in the Series F Preferred Stock by the amount of the distribution, and would recognize capital gain to the extent that the distribution exceeds your tax basis in the Series F Preferred Stock. Corporate shareholders will not be entitled to a dividends-received deduction on the portion of a distribution not paid out of MetLife, Inc.’s current or accumulated earnings and profits.

Further, U.S. Holders should be aware that dividends that exceed certain thresholds in relation to such holders’ tax basis in their Series F Preferred Stock could be characterized as “extraordinary dividends” (as defined in Section 1059 of the Code). Generally, a corporate holder of Series F Preferred Stock that receives an extraordinary dividend is required to reduce its stock basis by the portion of such dividend that is not taxed

S-36

because of the dividends received deduction and is required to recognize taxable gain to the extent such portion of the dividend exceeds the holder’s tax basis in such Series F Preferred Stock. U.S. Holders who are individuals and who receive an “extraordinary dividend” would be required to treat any losses on the sale of the Series F Preferred Stock as long-term capital losses to the extent such dividends received by them qualify for the 20% tax rate for qualified dividend income. Investors should consult their own tax advisors with respect to the potential application of the “extraordinary dividend” rules to an investment in MetLife, Inc.’s Series F Preferred Stock.

Sale or Exchange of the Series F Preferred Stock

If you sell or otherwise dispose of your Series F Preferred Stock (other than by redemption), you will generally recognize capital gain or loss equal to the difference between the amount realized upon the disposition and your adjusted tax basis in your Series F Preferred Stock. Capital gain of a noncorporate U.S. Holder is generally taxed at a maximum rate of 20% where the holder has a holding period greater than one year. All or a portion of your capital gain may be subject to an additional 3.8% tax imposed on “net investment income,” as described above. The deductibility of capital losses is subject to limitations.

Redemption of the Series F Preferred Stock

If MetLife, Inc. redeems your Series F Preferred Stock, the redemption generally will be a taxable event. You will generally recognize capital gain or loss on the redemption of the Series F Preferred Stock,provided that the redemption meets at least one of the following requirements as determined under U.S. federal income tax principles:

• the redemption results in a complete termination of your stock interest in MetLife, Inc.;

• the redemption is substantially disproportionate with respect to you; or

• the redemption is not essentially equivalent to a dividend with respect to you.

In determining whether any of these tests has been met, shares of stock considered to be owned by you by reason of certain constructive ownership rules set forth in Section 318 of the Code, as well as shares actually owned by you, must be taken into account. It may be more difficult for a person who owns, actually or constructively by operation of the attribution rules, any of MetLife, Inc.’s voting stock to satisfy any of the above requirements. Conversely, the redemption of the Series F Preferred Stock from an investor who does not own any of MetLife, Inc.’s voting stock (either actually or constructively) will be treated as a taxable sale of the Series F Preferred Stock.

If MetLife, Inc. redeems your Series F Preferred Stock in a redemption that meets one of the tests described above, you generally would recognize taxable gain or loss equal to the sum of the amount of cash and fair market value of property (other than MetLife, Inc.’s stock or the stock of MetLife, Inc.’s successor), including any amounts equal to accrued and unpaid dividends, received by you less your tax basis in the Series F Preferred Stock redeemed. Any such amounts equal to accrued and unpaid dividends on the Series F Preferred Stock will be treated by MetLife, Inc. as part of the redemption price and not as a dividend, unless a dividend has been declared during the then-current dividend period. This gain or loss would be long-term capital gain or capital loss if you have held the Series F Preferred Stock for more than one year. If the redemption does not satisfy any of the above requirements, then the entire amount received (without offset for your tax basis in your Series F Preferred Stock) in redemption of your Series F Preferred Stock will be treated as a distribution as described under “— U.S. Holders — Distributions on the Series F Preferred Stock” above. If a redemption of the Series F Preferred Stock is treated as a distribution that is taxable as a dividend and, subsequent to the redemption, for U.S. federal income tax purposes you continue to own (either actually or constructively) MetLife, Inc.’s stock, your tax basis in the redeemed Series F Preferred Stock would be transferred to your remaining shares of MetLife, Inc.’s stock. Prospective investors should consult their own tax advisors for purposes of determining the tax consequences resulting from a redemption of the Series F Preferred Stock.

S-37

Non-U.S. Holders

This section summarizes certain U.S. federal income and estate tax consequences of the ownership and disposition of Series F Preferred Stock by aNon-U.S. Holder. You are aNon-U.S. Holder if you are a beneficial owner of Series F Preferred Stock and you are, for U.S. federal income tax purposes:

• a nonresident alien individual;

• a foreign corporation; or

• an estate or trust that in either case is not subject to U.S. federal income tax on a net income basis on income or gain from the Series F Preferred Stock.

Dividends

Except as described below, if you are aNon-U.S. Holder, dividends (including the proceeds of a redemption of Series F Preferred Stock to the extent treated as a dividend, as described above) paid to you are subject to withholding of U.S. federal income tax at a 30% rate or at a lower rate if you are eligible for the benefits of an income tax treaty with the United States that provides for a lower rate. Even if you are eligible for a lower treaty rate, MetLife, Inc. and other payors will generally be required to withhold at a 30% rate (rather than the lower treaty rate) on dividend payments to you, unless you have furnished to the payor:

• a valid Internal Revenue Service FormW-8BEN (orW-8BEN-E, as applicable) or an acceptable substitute form upon which you certify, under penalties of perjury, that you are (or, in the case of aNon-U.S. Holder that is an estate or trust, such forms certifying that each beneficiary of the estate or trust is) not a U.S. person and are entitled to the lower treaty rate with respect to such payments; or

• in the case of payments made outside the United States to an offshore account (generally, an account maintained by you at an office or branch of a bank or other financial institution at any location outside the United States), other documentary evidence establishing your entitlement to the lower treaty rate in accordance with U.S. Treasury regulations.

If you are eligible for a reduced rate of U.S. withholding tax under a tax treaty, you may obtain a refund of any amounts withheld in excess of that rate by filing a refund claim with the U.S. Internal Revenue Service.

If dividends paid to you are “effectively connected” with your conduct of a trade or business within the United States, and, if required by a tax treaty, the dividends are attributable to a permanent establishment that you maintain in the United States, MetLife, Inc. and other payors generally are not required to withhold tax from the dividends,provided that you have furnished to MetLife, Inc. or another payor a valid Internal Revenue Service FormW-8ECI or an acceptable substitute form upon which you represent, under penalties of perjury, that:

• you are (or, in the case of aNon-U.S. Holder that is an estate or trust, such forms certifying that each beneficiary of the estate or trust is) not a U.S. person; and

• the dividends are effectively connected with your conduct of a trade or business within the United States and are includible in your gross income.

“Effectively connected” dividends are taxed at rates applicable to U.S. citizens, resident aliens and domestic U.S. corporations. If you are a corporateNon-U.S. Holder, “effectively connected” dividends that you receive may, under certain circumstances, be subject to an additional “branch profits tax” at a 30% rate or at a lower rate if you are eligible for the benefits of an income tax treaty with the United States that provides for a lower rate.

S-38

Gain on Disposition of the Series F Preferred Stock

Except as described below, if you are aNon-U.S. Holder, you generally will not be subject to U.S. federal income tax on gain that you recognize on a disposition (other than by redemption, to the extent the proceeds thereof are treated as a dividend, as described above) of Series F Preferred Stock unless:

• the gain is “effectively connected” with your conduct of a trade or business in the United States, and with respect to shareholders that are entitled to claim the benefits under certain tax treaties, the gain is attributable to a permanent establishment that you maintain in the United States;

• you are an individual, you hold the Series F Preferred Stock as a capital asset, you are present in the United States for 183 or more days in the taxable year of the disposition and certain other conditions exist; or

• MetLife, Inc. is or has been a “U.S. real property holding corporation” for U.S. federal income tax purposes and you held, directly or indirectly, at any time during the five-year period ending on the date of disposition, more than 5% of the Series F Preferred Stock and you are not eligible for any treaty exemption.

If you are a corporateNon-U.S. Holder, “effectively connected” gains that you recognize may also, under certain circumstances, be subject to an additional “branch profits tax” at a 30% rate or at a lower rate if you are eligible for the benefits of an income tax treaty with the United States that provides for a lower rate.

MetLife, Inc. has not been, is not and does not anticipate becoming a U.S. real property holding corporation for U.S. federal income tax purposes.

Federal Estate Taxes

Series F Preferred Stock held by aNon-U.S. Holder at the time of death will be included in the holder’s gross estate for U.S. federal estate tax purposes, unless an applicable estate tax treaty provides otherwise.

Foreign Account Tax Compliance Act

Pursuant to the Foreign Account Tax Compliance Act and related U.S. Treasury regulations (“FATCA”), a 30% withholding tax will be imposed on dividends paid with respect to Series F Preferred Stock paid to “foreign financial institutions” (includingnon-U.S. investment funds) or“non-financial foreign entities” (each as defined in the Code and U.S. Treasury regulations), unless they meet the information reporting and certification requirements of FATCA. To avoid withholding, a foreign financial institution will need to enter into an agreement with the Internal Revenue Service (an “FFI Agreement”) that states that it will provide the Internal Revenue Service certain information, including the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the Internal Revenue Service certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made tonon-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to its account holders. An intergovernmental agreement between the United States and an applicable foreign country (an “IGA”), or future U.S. Treasury regulations, may modify these requirements. Anon-financial foreign entity will need to provide either the name, address and taxpayer identification number of each substantial U.S. owner, or certifications of no substantial U.S. ownership to avoid withholding, unless certain exceptions apply. If Series F Preferred Stock is held through a foreign financial institution that has agreed to comply with the requirements of an FFI Agreement or is subject to similar requirements under applicable foreign law enacted in connection with an IGA, such foreign financial institution (or, in certain cases, a person paying amounts to such foreign financial institution) generally will be required, subject to certain exceptions, to withhold tax on payments made to (i) a person (including an individual) that fails to provide any required information or documentation or (ii) a foreign financial institution that has not agreed to comply with the requirements of an FFI Agreement and is not subject to similar requirements under applicable foreign law enacted in connection with an IGA.

Current provisions of the Code and U.S. Treasury regulations that govern FATCA withholding treat gross proceeds from the sale or other disposition of stock that can produce U.S.-sourced dividends (such as the Series F Preferred Stock) as subject to FATCA withholding after December 31, 2018. However, under proposed U.S. Treasury regulations (the preamble to which specifies that taxpayers are permitted to rely on them pending finalization), such gross proceeds are not subject to FATCA withholding.

You should consult your own tax advisors regarding FATCA and its effect on you.

Backup Withholding and Information Reporting

U.S. Holders

In general, if you are a noncorporate U.S. Holder you will be subject to information reporting requirements and will be subject to backup withholding tax on dividend payments, or on proceeds of a sale of the Series F Preferred Stock, made within the United States if:

• you fail to provide an accurate taxpayer identification number to the payor;

• you are notified by the U.S. Internal Revenue Service that you have failed to report all interest or dividends required to be shown on your federal income tax returns; or

• in certain circumstances, you fail to comply with applicable certification requirements.

If you sell your Series F Preferred Stock outside the United States through anon-U.S. office of anon-U.S. broker, and the sales proceeds are paid to you outside the United States, then U.S. backup withholding and information reporting requirements generally will not apply to that payment. However, U.S. information reporting, but not backup withholding, will apply to a payment of sales proceeds, even if that payment is made outside the United States, if you sell your Series F Preferred Stock through anon-U.S. office of a broker that is:

• a U.S. person;

• a controlled foreign corporation for U.S. tax purposes;

• a foreign person 50% or more of whose gross income is effectively connected with the conduct of a U.S. trade or business for a specified three-year period; or

• a foreign partnership, if at any time during its tax year: (1) one or more of its partners are “U.S. persons,” as defined in U.S. Treasury regulations, who in the aggregate hold more than 50% of the income or capital interest in the partnership; or (2) such foreign partnership is engaged in the conduct of a U.S. trade or business.

Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against your U.S. federal income tax liability provided the required information is furnished to the Internal Revenue Service on a timely basis.

Non-U.S. Holders

ANon-U.S. Holder will be subject to backup withholding on dividends paid to such holder unless such holder certifies under penalty of perjury that it is aNon-U.S. Holder (and the payor does not have actual knowledge or reason to know that such holder is a U.S. person as defined under the Code), or such holder otherwise establishes an exemption. Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale of the Series F Preferred Stock that are effected within the United States or conducted through certain United States-related financial intermediaries, unless the beneficial owner certifies under penalty of perjury that it is aNon-U.S. Holder (and the payor does not have actual knowledge or

S-40

reason to know that the beneficial owner is a U.S. person as defined under the Code) or such owner of MetLife, Inc.’s Series F Preferred Stock otherwise establishes an exemption.

Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against your U.S. federal income tax liability,provided the required information is furnished to the Internal Revenue Service on a timely basis.

	Underwriting Discount
Per Depositary Share (1)	$	0.6618
Total	$	26,472,762.50

(1) Reflects 30,647,000 Depositary Shares sold to retail investors, for which the underwriters will receive an underwriting discount of $0.7875 per Depositary Share, and 9,353,000 Depositary Shares sold to institutional investors, for which the underwriters will receive an underwriting discount of $0.2500 per Depositary Share.

Depositary Shares sold by the underwriters to the public will initially be offered at the price to the public set forth on the cover of this prospectus supplement. Any Depositary Shares sold by the underwriters to securities dealers may be sold at a discount from the price to the public of up to $0.5000 per Depositary Share from the price to the public. Any such securities dealers may resell any Depositary Shares purchased from the underwriters to certain other brokers or dealers at a discount from the price to the public of up to $0.4500 per Depositary Shares from the price to the public. If all the Depositary Shares are not sold at the price to the public, the underwriters may change the offering price and the other selling terms.

S-42

We intend to apply to list the Depositary Shares on the New York Stock Exchange under the symbol “MET PRF”. If approved, we expect trading of the Depositary Shares on the New York Stock Exchange to begin within 30 days after the original issue date. We do not expect that there will be any separate public trading market for the shares of Series F Preferred Stock except as represented by the Depositary Shares.

In addition, MetLife, Inc. has agreed with the underwriters not to issue, offer, sell, contract to offer or sell or otherwise dispose of, any shares of U.S. dollar denominated preferred stock or any debt securities substantially similar to U.S. dollar denominated preferred stock exceeding an aggregate liquidation preference and principal amount of $3.0 billion, except debt securities issued under the Global Note Issuance Program of Metropolitan Life Global Funding I, the Global Note Issuance Program of Met Tower Global Funding or any commercial paper program, during the period beginning on the date of the Underwriting Agreement and continuing to the settlement of this offering of Depositary Shares, except with the prior written consent of the representatives.

Some or all of our officers and directors may purchase the Depositary Shares in the offering.

MetLife, Inc. estimates that its expenses for this offering will be approximately $1.0 million.

MetLife, Inc. has agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments which the underwriters may be required to make in respect of any such liabilities.

In connection with the offering of the Depositary Shares, the representatives may engage in transactions that have the effect of stabilizing, maintaining or otherwise affecting the price of the Depositary Shares. Specifically, the representatives may overallot in connection with the offering of the Depositary Shares, creating a syndicate short position. In addition, the representatives may bid for, and purchase, Depositary Shares in the open market to cover syndicate short positions. Finally, the representatives may reclaim selling concessions allowed for distributing the Depositary Shares in the offering of the Depositary Shares, if the representatives repurchase previously distributed Depositary Shares in syndicate covering transactions, stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the Depositary Shares above independent market levels. The representatives are not required to engage in any of these activities, may end any of them at any time, and must bring them to an end after a limited period.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial andnon-financial activities and services. In the ordinary course of their respective businesses, the underwriters and their affiliates have engaged, and may in the future engage, in commercial, investment or retail banking transactions with us and our affiliates for which they have in the past received, and may in the future receive, customary fees and commissions for these transactions.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investment and securities activities may involve securities and/or instruments of MetLife, Inc. or our affiliates, including the Depositary Shares. If any of the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Depositary Shares offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the Depositary Shares offered hereby. The underwriters and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments. Certain of the underwriters or their affiliates are lenders under MetLife, Inc.’s credit agreements.

S-43

Alternative Settlement Cycle

It is expected that delivery of the Depositary Shares will be made against payment therefor on or about January 15, 2020, which is the sixth business day following the date hereof (such settlement cycle being referred to as “T+6”). Pursuant to Rule15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Depositary Shares prior to their date of delivery may be required, by virtue of the fact that the Depositary Shares initially will settle in T+6, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the Depositary Shares who wish to trade such Depositary Shares prior to their date of delivery should consult their own advisors.

Notice to Prospective Investors in the United States of America

The Depositary Shares may not be acquired or held by any person who is an employee benefit plan or other plan or arrangement subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), or Section 4975 of the Code, or who is acting on behalf of or investing the assets of any such plan or arrangement, unless the acquisition and holding of the Depositary Shares by such person will not result in anon-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code.

Offering Restrictions

Each underwriter has represented and agreed with MetLife, Inc. as set forth below with respect to the following jurisdictions:

European Economic Area

In relation to each member state (each, a “Member State”) of the European Economic Area (the “EEA”), no offer of Depositary Shares may be made to the public in that Member State other than to any legal entity which is a qualified investor as defined in the Prospectus Regulation, providedthat no such offer of Depositary Shares shall require MetLife, Inc. or any underwriter to publish a prospectus pursuant to Article 3 of the Prospectus Regulation or supplement a prospectus pursuant to Article 23 of the Prospectus Regulation.

For the purposes of this section, (i) the expression an “offer of Depositary Shares to the public” in relation to any Depositary Shares in any Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Depositary Shares to be offered so as to enable an investor to decide to purchase or subscribe for the Depositary Shares and (ii) the expression “Prospectus Regulation” means Regulation (EU) 2017/1129 (as amended or superseded).

This prospectus supplement and accompanying prospectus has been prepared on the basis that any offer of the Depositary Shares in any Member State of the EEA will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of the Depositary Shares. This prospectus supplement and accompanying prospectus is not a prospectus for the purposes of the Prospectus Regulation.

The Depositary Shares are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended or superseded, “MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended or superseded), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a “qualified investor” as defined in the Prospectus Regulation. Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended or

S-44

superseded, the “PRIIPs Regulation”) for offering or selling the Depositary Shares or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Depositary Shares or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

United Kingdom

In the United Kingdom, this prospectus supplement and the accompanying prospectus are being distributed only to, and are directed only at, persons who are “qualified investors” (as defined in the Prospectus Regulation) (i) who have professional experience in matters relating to investments falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (as amended, the “Order”), (ii) who are high net worth companies (or persons to whom it may otherwise be lawfully communicated) falling within Article 49(2)(a) to (d) of the Order or (iii) who are persons to whom it would otherwise be lawful to distribute it (all such persons together being referred to as “relevant persons”).

Any person in the United Kingdom that is not a relevant person should not act or rely on the information included in this prospectus supplement or the accompanying prospectus, or use it as basis for taking any action. In the United Kingdom, any investment or investment activity that this prospectus supplement or the accompanying prospectus relates to may be made or taken exclusively by relevant persons.

The Depositary Shares may be sold only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the Depositary Shares must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement and the accompanying prospectus contains a misrepresentation,provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument33-105 Underwriting Conflicts (NI33-105), the underwriters are not required to comply with the disclosure requirements of NI33-105 regarding underwriter conflicts of interest in connection with this offering.

Hong Kong

ABOUT THIS PROSPECTUS

Unless otherwise stated or the context otherwise requires, references in this prospectus to “MetLife,” “we,” “our,” “us,” or “the Company” refer to MetLife, Inc., a Delaware corporation incorporated in 1999, together with its subsidiaries and affiliates, while references to “MetLife, Inc.” refer only to the holding company on an unconsolidated basis.

This prospectus is part of a registration statement that MetLife, Inc. filed with the U.S. Securities and Exchange Commission (the “SEC”) using a “shelf” registration process. Under this shelf process, MetLife, Inc. may, from time to time, sell any combination of debt securities, preferred stock, depositary shares, common stock, warrants, purchase contracts and units in one or more offerings in one or more currencies, currency units or composite currencies. This prospectus provides you with a general description of the securities MetLife, Inc. may offer. Each time that securities are sold, a prospectus supplement that will contain specific information about the terms of that offering will be provided. The prospectus supplement may also add, update or change information contained in this prospectus.

RISK FACTORS

Investing in MetLife, Inc.’s securities involves risks. We urge you to carefully consider the risk factors described in our filings with the SEC that are incorporated by reference in this prospectus and in any prospectus supplement, pricing supplement or free writing prospectus used in connection with an offering of our securities, as well as the information relating to us identified herein in “Special Note Regarding Forward-Looking Statements,” before making an investment decision.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the accompanying prospectus supplement may contain or incorporate by reference information that includes or is based upon forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements give expectations or forecasts of future events. These statements can be identified by the fact that they do not relate strictly to historical or current facts. They use words and terms such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “will,” and other words and terms of similar meaning, or are tied to future periods, in connection with a discussion of future performance. In particular, these include statements relating to future actions, prospective services or products, future performance or results of current and anticipated services or products, sales efforts, expenses, the outcome of contingencies such as legal proceedings, trends in operations and financial results.

Many factors will be important in determining the results of MetLife, Inc., its subsidiaries and affiliates. Forward-looking statements are based on our assumptions and current expectations, which may be inaccurate, and on the current economic environment, which may change. These statements are not guarantees of future performance. They involve a number of risks and uncertainties that are difficult to predict. Results could differ materially from those expressed or implied in the forward-looking statements. Risks, uncertainties, and other

MetLife is organized into five segments: U.S.; Asia; Latin America; Europe, the Middle East and Africa; and MetLife Holdings. In addition, the Company reports certain of its results of operations in Corporate & Other. See “Business — Segments and Corporate & Other” and Note 2 of the Notes to the Consolidated Financial Statements in the 2018 Annual Report incorporated by reference herein and Note 2 of the Notes to the Interim Condensed Consolidated Financial Statements in the First, Second and Third QuarterForms 10-Q incorporated by reference herein for further information on MetLife’s segments and Corporate & Other. Management continues to evaluate the Company’s segment performance and allocated resources and may adjust related measurements in the future to better reflect segment profitability.

MetLife, Inc. is a holding company for its insurance and financial subsidiaries and does not have any significant operations of its own. Dividends from its subsidiaries and permitted payments to it under its tax sharing arrangements with its subsidiaries are its principal sources of cash to meet its obligations and to pay preferred and common stock dividends. MetLife, Inc.’s insurance subsidiaries are subject to regulatory restrictions on the payment of dividends imposed by the regulators of their respective domiciles. The dividend limitation for U.S. insurance subsidiaries is based on the surplus to policyholders at the end of the immediately

4

preceding calendar year and statutory net gain from operations of the immediately preceding calendar year. Statutory accounting practices, as prescribed by insurance regulators of various states in which we conduct business, differ in certain respects from accounting principles used in financial statements prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The significant differences relate to the treatment of deferred policy acquisition costs, certain deferred income tax, required investment liabilities, statutory, reserve calculation assumptions, goodwill and surplus notes.

MetLife, Inc. is incorporated under the laws of the State of Delaware. MetLife, Inc.’s principal executive offices are located at 200 Park Avenue, New York, New York 10166-0188, its telephone number is212-578-9500 and its internet address is www.metlife.com.

DESCRIPTION OF SECURITIES

This prospectus contains summary descriptions of the debt securities, preferred stock, depositary shares, common stock, warrants, purchase contracts and units that MetLife, Inc. may sell from time to time. These summary descriptions are not meant to be complete descriptions of each security. However, this prospectus and the applicable prospectus supplement together contain the material terms of the securities being offered.

DESCRIPTION OF DEBT SECURITIES

As used in this prospectus, debt securities means the debentures, notes, bonds and other evidences of indebtedness that MetLife, Inc. may issue from time to time. The debt securities will either be senior debt securities or subordinated debt securities.

Unless the applicable prospectus supplement states otherwise, senior debt securities will be issued under the Senior Indenture, dated as of November 9, 2001 (the “Senior Indenture”), between MetLife, Inc. and The Bank of New York Mellon Trust Company, N.A. (as successor in interest to J.P. Morgan Trust Company, National Association (as successor to Bank One Trust Company, N.A.)), as trustee, and subordinated debt securities will be issued under the Subordinated Indenture, dated as of June 21, 2005 (the “Subordinated Indenture”), between MetLife, Inc. and The Bank of New York Mellon Trust Company, N.A. (as successor in interest to J.P. Morgan Trust Company, National Association), as trustee. This prospectus sometimes refers to the Senior Indenture and the Subordinated Indenture collectively as the “Indentures.”

The Senior Indenture and the Subordinated Indenture are incorporated by reference as exhibits to the registration statement of which this prospectus forms a part. The statements and descriptions in this prospectus or in any prospectus supplement regarding provisions of the Indentures and debt securities are summaries thereof, do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the Indentures and the debt securities, including the definitions therein of certain terms.

General

The debt securities will be direct unsecured obligations of MetLife, Inc. The senior debt securities will rank equally with all of MetLife, Inc.’s other senior and unsubordinated debt. The subordinated debt securities will be subordinate and junior in right of payment to all of MetLife, Inc.’s present and future senior indebtedness.

Because MetLife, Inc. is principally a holding company, its right to participate in any distribution of assets of any subsidiary, including Metropolitan Life Insurance Company, upon the subsidiary’s liquidation or reorganization or otherwise, is subject to the prior claims of creditors of the subsidiary, except to the extent MetLife, Inc. may be recognized as a creditor of that subsidiary. Accordingly, MetLife, Inc.’s obligations under the debt securities will be effectively subordinated to all existing and future indebtedness and liabilities of its subsidiaries, including liabilities under contracts of insurance and annuities written by MetLife, Inc.’s insurance subsidiaries, and holders of debt securities should look only to MetLife, Inc.’s assets for payment thereunder.

The Indentures do not limit the aggregate principal amount of debt securities that MetLife, Inc. may issue and provide that MetLife, Inc. may issue debt securities from time to time in one or more series, in each case with the same or various maturities, at par or at a discount. MetLife, Inc. may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series outstanding at the time of the issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of debt securities under the applicable Indenture. None of the Indentures limit our ability to incur other debt.

Each prospectus supplement will describe the terms relating to the specific series of debt securities being offered. These terms will include some or all of the following:

• the title of debt securities and whether they are subordinated debt securities or senior debt securities;

• any limit on the aggregate principal amount of the debt securities;

• the price or prices at which MetLife, Inc. will sell the debt securities;

• the maturity date or dates of the debt securities;

7

• the rate or rates of interest, if any, which may be fixed or variable, per annum at which the debt securities will bear interest, or the method of determining such rate or rates, if any;

• the date or dates from which any interest will accrue, the dates on which interest will be payable, or the method by which such date or dates will be determined;

• the right, if any, to extend the interest payment periods and the duration of any such deferral period, including the maximum consecutive period during which interest payment periods may be extended;

• whether the amount of payments of principal of (and premium, if any) or interest on the debt securities may be determined with reference to any index, formula or other method, such as one or more currencies, commodities, equity indices or other indices, and the manner of determining the amount of such payments;

• the dates on which MetLife, Inc. will pay interest on the debt securities and the regular record date for determining who is entitled to the interest payable on any interest payment date;

• the place or places where the principal of (and premium, if any) and interest on the debt securities will be payable;

• if MetLife, Inc. possesses the option to do so, the periods within which and the prices at which MetLife, Inc. may redeem the debt securities, in whole or in part, pursuant to optional redemption provisions, and the other terms and conditions of any such provisions;

• MetLife, Inc.’s obligation, if any, to redeem, repay or purchase debt securities by making periodic payments to a sinking fund or through an analogous provision or at the option of holders of the debt securities, and the period or periods within which and the price or prices at which MetLife, Inc. will redeem, repay or purchase the debt securities, in whole or in part, pursuant to such obligation, and the other terms and conditions of such obligation;

• the denominations in which the debt securities will be issued, if other than denominations of $1,000 and integral multiples of $1,000;

• the portion, or methods of determining the portion, of the principal amount of the debt securities which MetLife, Inc. must pay upon the acceleration of the maturity of the debt securities in connection with an Event of Default (as described below), if other than the full principal amount;

• the currency, currencies or currency unit in which MetLife, Inc. will pay the principal of (and premium, if any) or interest, if any, on the debt securities, if not U.S. dollars and the manner of determining the equivalent thereof in U.S. dollars;

• provisions, if any, granting special rights to holders of the debt securities upon the occurrence of specified events;

• any deletions from, modifications of or additions to the Events of Default or MetLife, Inc.’s covenants with respect to the applicable series of debt securities, and whether or not such Events of Default or covenants are consistent with those contained in the applicable Indenture;

• the application, if any, of the terms of the Indenture relating to defeasance and covenant defeasance (which terms are described below) to the debt securities;

• whether the subordination provisions summarized below or different subordination provisions will apply to the debt securities;

• the terms, if any, upon which the holders may or are required to convert or exchange such debt securities into or for MetLife, Inc.’s common stock or other securities or property or into securities of a third party, including conversion price (which may be adjusted), the method of calculating the conversion price, or the conversion period;

• whether any of the debt securities will be issued in global or certificated form and, if so, the terms and conditions upon which global debt securities may be exchanged for certificated debt securities;

8

• any change in the right of the trustee or the requisite holders of debt securities to declare the principal amount thereof due and payable because of an Event of Default;

• the depositary for global or certificated debt securities;

• if applicable, a discussion of certain material U.S. federal income tax considerations applicable to specific debt securities;

• any trustees, authenticating or paying agents, transfer agents or registrars or other agents with respect to the debt securities; and

• any other terms of the debt securities not inconsistent with the provisions of the Indentures, as amended or supplemented.

Unless otherwise specified in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange.

Unless otherwise specified in the applicable prospectus supplement, the debt securities will be issued in fully registered form without coupons.

Debt securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate which at the time of issuance is below market rates. The applicable prospectus supplement will describe the federal income tax consequences and special considerations applicable to any such debt securities. The debt securities may also be issued as indexed securities or securities denominated in foreign currencies or currency units, as described in more detail in the prospectus supplement relating to any of the particular debt securities. The prospectus supplement relating to specific debt securities will also describe any special considerations and certain additional tax considerations applicable to such debt securities.

Subordination

The prospectus supplement relating to any offering of subordinated debt securities will describe the specific subordination provisions. However, unless otherwise noted in the prospectus supplement, subordinated debt securities will be subordinate and junior in right of payment to all of MetLife, Inc.’s Senior Indebtedness (as described below).

For purposes of subordinated debt securities, “Senior Indebtedness” means all amounts due on obligations in connection with any of the following, whether outstanding at the date of execution of the Subordinated Indenture or thereafter incurred or created:

• the principal of (and premium, if any) and interest in respect of indebtedness of MetLife, Inc. for borrowed money and indebtedness evidenced by securities, debentures, bonds or other similar instruments issued by MetLife, Inc.;

• all capital lease obligations of MetLife, Inc.;

• all obligations of MetLife, Inc. issued or assumed as the deferred purchase price of property, all conditional sale obligations of MetLife, Inc. and all obligations of MetLife, Inc. under any title retention agreement (but excluding trade accounts payable in the ordinary course of business);

• all obligations of MetLife, Inc. for the reimbursement on any letter of credit, banker’s acceptance, security purchase facility or similar credit transaction;

• all obligations of MetLife, Inc. in respect of interest rate swap, cap or other agreements, interest rate future or options contracts, currency swap agreements, currency future or option contracts and other similar agreements;

• all obligations of the types referred to above of other persons for the payment of which MetLife, Inc. is responsible or liable as obligor, guarantor or otherwise; and

9

• all obligations of the types referred to above of other persons secured by any lien on any property or asset of MetLife, Inc. (whether or not such obligation is assumed by MetLife, Inc.).

Senior Indebtedness does not include:

• indebtedness or monetary obligations to trade creditors created or assumed by MetLife, Inc. in the ordinary course of business in connection with the obtaining of materials or services;

• indebtedness that is, by its terms, subordinated to, or ranks equal with, the subordinated debt securities; and

• any indebtedness of MetLife, Inc. to its affiliates (including all debt securities and guarantees in respect of those debt securities issued to any trust, partnership or other entity affiliated with MetLife, Inc. that is a financing vehicle of MetLife, Inc. in connection with the issuance by such financing entity of preferred securities or other securities guaranteed by MetLife, Inc.) unless otherwise expressly provided in the terms of any such indebtedness.

At September 30, 2019 and December 31, 2018, Senior Indebtedness aggregated approximately $12.4 billion and $11.8 billion, respectively. The amount of Senior Indebtedness which MetLife, Inc. may issue is subject to limitations imposed by its board of directors.

Senior Indebtedness will continue to be Senior Indebtedness and be entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any term of such Senior Indebtedness.

Unless otherwise noted in the accompanying prospectus supplement, if MetLife, Inc. defaults in the payment of any principal of (or premium, if any) or interest on any Senior Indebtedness when it becomes due and payable, whether at maturity or at a date fixed for prepayment or by declaration or otherwise, then, unless and until such default is cured or waived or ceases to exist, MetLife, Inc. will make no direct or indirect payment (in cash, property, securities, byset-off or otherwise) in respect of the principal of or interest on the subordinated debt securities or in respect of any redemption, retirement, purchase or other requisition of any of the subordinated debt securities.

In the event of the acceleration of the maturity of any subordinated debt securities, the holders of all senior debt securities outstanding at the time of such acceleration will first be entitled to receive payment in full of all amounts due on the senior debt securities before the holders of the subordinated debt securities will be entitled to receive any payment of principal (and premium, if any) or interest on the subordinated debt securities.

If any of the following events occurs, MetLife, Inc. will pay in full all Senior Indebtedness before it makes any payment or distribution under the subordinated debt securities, whether in cash, securities or other property, to any holder of subordinated debt securities:

• any dissolution orwinding-up or liquidation or reorganization of MetLife, Inc., whether voluntary or involuntary or in bankruptcy, insolvency or receivership;

• any general assignment by MetLife, Inc. for the benefit of creditors; or

• any other marshaling of MetLife, Inc.’s assets or liabilities.

In such event, any payment or distribution under the subordinated debt securities, whether in cash, securities or other property, which would otherwise (but for the subordination provisions) be payable or deliverable in respect of the subordinated debt securities, will be paid or delivered directly to the holders of Senior Indebtedness in accordance with the priorities then existing among such holders until all Senior Indebtedness has been paid in full. If any payment or distribution under the subordinated debt securities is received by the trustee of any subordinated debt securities in contravention of any of the terms of the Subordinated Indenture and before all the

10

Senior Indebtedness has been paid in full, such payment or distribution or security will be received in trust for the benefit of, and paid over or delivered and transferred to, the holders of the Senior Indebtedness at the time outstanding in accordance with the priorities then existing among such holders for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all such Senior Indebtedness in full.

None of the Indentures limit the issuance of additional Senior Indebtedness.

Restrictive Covenants

Unless an accompanying prospectus supplement states otherwise, the following restrictive covenants will apply to each series of senior debt securities:

Limitation on Liens. So long as any senior debt securities are outstanding, neither MetLife, Inc. nor any of its subsidiaries will create, assume, incur or guarantee any debt which is secured by any mortgage, pledge, lien, security interest or other encumbrance on any capital stock of:

• Metropolitan Life Insurance Company;

• any successor to substantially all of the business of Metropolitan Life Insurance Company which is also a subsidiary of MetLife, Inc.; or

• any corporation (other than MetLife, Inc.) having direct or indirect control of Metropolitan Life Insurance Company or any such successor.

However, this restriction will not apply if the debt securities then outstanding are secured at least equally and ratably with the otherwise prohibited secured debt so long as it is outstanding.

Limitations on Dispositions of Stock of Certain Subsidiaries. So long as any senior debt securities are outstanding and subject to the provisions of the Senior Indenture regarding mergers, consolidations and sales of assets, neither MetLife, Inc. nor any of its subsidiaries will sell or otherwise dispose of any shares of capital stock (other than preferred stock having no voting rights of any kind) of:

• Metropolitan Life Insurance Company;

• any successor to substantially all of the business of Metropolitan Life Insurance Company which is also a subsidiary of MetLife, Inc.; or

• any corporation (other than MetLife, Inc.) having direct or indirect control of Metropolitan Life Insurance Company or any such successor;

except for, in each case:

• a sale or other disposition of any of such stock to a wholly-owned subsidiary of MetLife, Inc. or of such subsidiary; or

• a sale or other disposition of all of such stock for at least fair value (as determined by MetLife, Inc.’s board of directors acting in good faith); or a sale or other disposition required to comply with an order of a court or regulatory authority of competent jurisdiction, other than an order issued at MetLife, Inc.’s request or the request of any of MetLife, Inc.’s subsidiaries.

Limitations on Consolidation, Merger, Sale of Assets and Other Transactions.(i) MetLife, Inc. may not merge with or into or consolidate with another corporation or sell, assign, transfer, lease or convey all or substantially all of its properties and assets to, any other corporation other than a direct or indirect wholly-owned subsidiary of MetLife, Inc. and (ii) no corporation may merge with or into or consolidate with MetLife, Inc. or,

11

except for any direct or indirect wholly-owned subsidiary of MetLife, Inc., sell, assign, transfer, lease or convey all or substantially all of its properties and assets to MetLife, Inc., unless:

• MetLife, Inc. is the surviving corporation or the corporation formed by or surviving such merger or consolidation or to which such sale, assignment, transfer, lease or conveyance has been made, if other than MetLife, Inc., has expressly assumed by supplemental indenture all the obligations of MetLife, Inc. under the debt securities and the Indentures;

• immediately after giving effect to such transaction, no default or Event of Default has occurred and is continuing; and

• MetLife, Inc. delivers to the trustee an officers’ certificate and an opinion of counsel, each stating that the supplemental indenture complies with the applicable Indenture.

Events of Default, Notice and Waiver

Unless an accompanying prospectus supplement states otherwise, the following will constitute “Events of Default” under the Indentures with respect to each series of debt securities:

• MetLife, Inc.’s failure to pay any interest on any debt security of such series when due and payable, continued for 30 days;

• MetLife, Inc.’s failure to pay principal (or premium, if any) on any debt security of such series when due, regardless of whether such payment became due because of maturity, redemption, acceleration or otherwise, or is required by any sinking fund established with respect to such series;

• MetLife, Inc.’s failure to observe or perform any other of its covenants or agreements with respect to such series for 90 days after MetLife, Inc. receives notice of such failure;

• certain defaults with respect to MetLife, Inc.’s debt which result in a principal amount in excess of $100,000,000 becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable (other than the debt securities ornon-recourse debt); and

• certain events of bankruptcy, insolvency or reorganization of MetLife, Inc.

If an Event of Default with respect to any debt securities of any series outstanding under either of the Indentures shall occur and be continuing, the trustee under such Indenture or the holders of at least 25% in aggregate principal amount of the debt securities of that series outstanding may declare, by notice as provided in the applicable Indenture, the principal amount (or such lesser amount as may be provided for in the debt securities of that series) of all the debt securities of that series outstanding to be due and payable immediately;provided that, in the case of an Event of Default involving certain events in bankruptcy, insolvency or reorganization, acceleration is automatic; and,provided further, that after such acceleration, but before a judgment or decree based on acceleration, the holders of a majority in aggregate principal amount of the outstanding debt securities of that series may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal, have been cured or waived. Upon the acceleration of the maturity of original issue discount debt securities, an amount less than the principal amount thereof will become due and payable. Reference is made to the prospectus supplement relating to any original issue discount debt securities for the particular provisions relating to acceleration of maturity thereof.

Any past default under either Indenture with respect to debt securities of any series, and any Event of Default arising therefrom, may be waived by the holders of a majority in principal amount of all debt securities of such series outstanding under such Indenture, except in the case of (i) default in the payment of the principal of (or premium, if any) or interest on any debt securities of such series, or (ii) default in respect of a covenant or provision which may not be amended or modified without the consent of the holder of each outstanding debt security of such series affected.

The trustee is required, within 90 days after the occurrence of a default (which is known to the trustee and is continuing), with respect to the debt securities of any series (without regard to any grace period or notice requirements), to give to the holders of the debt securities of such series notice of such default;provided, however, that, except in the case of a default in the payment of the principal of (and premium, if any) or interest, or in the payment of any sinking fund installment, on any debt securities of such series, the trustee will be protected in withholding such notice if it in good faith determines that the withholding of such notice is in the interests of the holders of the debt securities of such series.

The trustee, subject to its duties during default to act with the required standard of care, may require indemnification by the holders of the debt securities of any series with respect to which a default has occurred before proceeding to exercise any right or power under the applicable Indenture at the request of the holders of the debt securities of such series. Subject to such right of indemnification and to certain other limitations, the holders of a majority in aggregate principal amount of the outstanding debt securities of any series under the applicable Indenture may direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee with respect to the debt securities of such series.

No holder of a debt security of any series may institute any action against MetLife, Inc. under either of the Indentures (except actions for payment of overdue principal of (and premium, if any) or interest on such debt security or for the conversion or exchange of such debt security in accordance with its terms) unless (i) the holder has given to the trustee written notice of an Event of Default and of the continuance thereof with respect to the debt securities of such series specifying an Event of Default, as required under the applicable Indenture, (ii) the holders of at least 25% in aggregate principal amount of the debt securities of that series then outstanding under such Indenture shall have requested the trustee to institute such action and offered to the trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, and (iii) the trustee shall not have instituted such action within 60 days of such request.

MetLife, Inc. is required to furnish annually to the trustee statements as to MetLife, Inc.’s compliance with all conditions and covenants under each Indenture.

Discharge, Defeasance and Covenant Defeasance

If indicated in the applicable prospectus supplement, MetLife, Inc. may discharge or defease its obligations under each Indenture as set forth below.

MetLife, Inc. may discharge certain obligations to holders of any series of debt securities issued under either the Senior Indenture or the Subordinated Indenture which have not already been delivered to the trustee for cancellation and which have either become due and payable or are by their terms due and payable within one year (or scheduled for redemption within one year) by irrevocably depositing with the trustee cash or, in the case of debt securities payable only in U.S. dollars, U.S. government obligations (as defined in the applicable Indenture), as trust funds in an amount certified to be sufficient to pay when due, whether at maturity, upon redemption or otherwise, the principal of (and premium, if any) and interest on such debt securities.

If indicated in the applicable prospectus supplement, MetLife, Inc. may elect either (i) to defease and be discharged from any and all obligations with respect to the debt securities of or within any series (except as otherwise provided in the relevant Indenture) (“defeasance”) or (ii) to be released from its obligations with respect to certain covenants applicable to the debt securities of or within any series (“covenant defeasance”), upon the deposit with the relevant trustee, in trust for such purpose, of money and/or government obligations which, through the payment of principal and interest in accordance with their terms, will provide money in an amount sufficient, without reinvestment, to pay the principal of (and premium, if any) or interest on such debt securities to maturity or redemption, as the case may be, and any mandatory sinking fund or analogous payments thereon. As a condition to defeasance or covenant defeasance, MetLife, Inc. must deliver to the trustee an opinion

13

of counsel to the effect that the holders of such debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance had not occurred. Such opinion of counsel, in the case of defeasance under clause (i) above, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable U.S. federal income tax law occurring after the date of the relevant Indenture. In addition, in the case of either defeasance or covenant defeasance, MetLife, Inc. shall have delivered to the trustee (i) an officers’ certificate to the effect that the relevant debt securities exchange(s) have informed it that neither such debt securities nor any other debt securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit, and (ii) an officers’ certificate and an opinion of counsel, each stating that all conditions precedent with respect to such defeasance or covenant defeasance have been complied with.

MetLife, Inc. may exercise its defeasance option with respect to such debt securities notwithstanding its prior exercise of its covenant defeasance option.

Modification and Waiver

Under the Indentures, MetLife, Inc. and the applicable trustee may supplement the Indentures for certain purposes which would not materially adversely affect the interests or rights of the holders of debt securities of a series without the consent of those holders. MetLife, Inc. and the applicable trustee may also modify the Indentures or any supplemental indenture in a manner that affects the interests or rights of the holders of debt securities with the consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each affected series issued under the Indenture. However, the Indentures require the consent of each holder of debt securities that would be affected by any modification which would:

• extend the fixed maturity of any debt securities of any series, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof;

• reduce the amount of principal of an original issue discount debt security or any other debt security payable upon acceleration of the maturity thereof;

• change the currency in which any debt security or any premium or interest is payable;

• impair the right to enforce any payment on or with respect to any debt security;

• adversely change the right to convert or exchange, including decreasing the conversion rate or increasing the conversion price of, any debt security (if applicable);

• reduce the percentage in principal amount of outstanding debt securities of any series, the consent of whose holders is required for modification or amendment of the Indentures or for waiver of compliance with certain provisions of the Indentures or for waiver of certain defaults;

• reduce the requirements contained in the Indentures for quorum or voting; or

• modify any of the above provisions.

Each Indenture permits the holders of at least a majority in aggregate principal amount of the outstanding debt securities of any series issued under such Indenture which is affected by the modification or amendment to waive MetLife, Inc.’s compliance with certain covenants contained in such Indenture.

Payment and Paying Agents

Unless otherwise indicated in the applicable prospectus supplement, payment of interest on a debt security on any interest payment date will be made to the person in whose name a debt security is registered at the close of business on the record date for the interest.

14

Unless otherwise indicated in the applicable prospectus supplement, principal, interest and premium on the debt securities of a particular series will be payable at the office of such paying agent or paying agents as MetLife, Inc. may designate for such purpose from time to time. Notwithstanding the foregoing, at MetLife, Inc.’s option, payment of any interest may be made by check mailed to the address of the person entitled thereto as such address appears in the security register.

Unless otherwise indicated in the applicable prospectus supplement, a paying agent designated by MetLife, Inc. and located in the Borough of Manhattan, The City of New York, will act as paying agent for payments with respect to debt securities of each series. All paying agents initially designated by MetLife, Inc. for the debt securities of a particular series will be named in the applicable prospectus supplement. MetLife, Inc. may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts, except that MetLife, Inc. will be required to maintain a paying agent in each place of payment for the debt securities of a particular series.

All moneys paid by MetLife, Inc. to a paying agent for the payment of the principal, interest or premium on any debt security which remain unclaimed at the end of two years after such principal, interest or premium has become due and payable will be repaid to MetLife, Inc. upon request, and the holder of such debt security thereafter may look only to MetLife, Inc. for payment thereof.

Denominations, Registrations and Transfer

Unless an accompanying prospectus supplement states otherwise, debt securities will be represented by one or more global certificates registered in the name of a nominee for The Depository Trust Company (“DTC”). In such case, each holder’s beneficial interest in the global securities will be shown on the records of DTC and transfers of beneficial interests will only be effected through DTC’s records.

A holder of debt securities may only exchange a beneficial interest in a global security for certificated securities registered in the holder’s name in limited circumstances, as described in an applicable prospectus supplement.

If debt securities are issued in certificated form, they will only be issued in the minimum denomination specified in the accompanying prospectus supplement and integral multiples of such denomination. Transfers and exchanges of such debt securities will only be permitted in such minimum denomination. Transfers of debt securities in certificated form may be registered at the trustee’s corporate office or at the offices of any paying agent or trustee appointed by MetLife, Inc. under the Indentures. Exchanges of debt securities for an equal aggregate principal amount of debt securities in different denominations may also be made at such locations.

Governing Law

The Indentures and debt securities will be governed by, and construed in accordance with, the internal laws of the State of New York, without regard to its principles of conflicts of laws.

Relationship with the Trustees

The trustee under (i) the Senior Indenture is The Bank of New York Mellon Trust Company, N.A. (as successor in interest to J.P. Morgan Trust Company, National Association (as successor to Bank One Trust Company, N.A.)) and (ii) the Subordinated Indenture is The Bank of New York Mellon Trust Company, N.A. (as successor in interest to J.P. Morgan Trust Company, National Association). MetLife, Inc. and its subsidiaries maintain ordinary banking and trust relationships with a number of banks and trust companies, including the trustee under the Indentures.

15

Conversion or Exchange Rights

The prospectus supplement will describe the terms, if any, on which a series of debt securities may be convertible into or exchangeable for securities described in this prospectus. These terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at MetLife, Inc.’s option. These provisions may allow or require the number of shares of MetLife, Inc.’s common stock or other securities to be received by the holders of such series of debt securities to be adjusted.

16

Common Stock

Dividends. The holders of common stock, after any preferences of holders of any preferred stock, are entitled to receive dividends as determined by MetLife, Inc.’s board of directors. The declaration and payment of common stock dividends will also depend on MetLife, Inc.’s financial condition, results of operations, cash requirements, future prospects, regulatory restrictions on the payment of dividends by MetLife, Inc.’s insurance subsidiaries and other factors deemed relevant by MetLife, Inc.’s board of directors. There is no requirement or assurance that MetLife, Inc. will declare and pay any dividends. The certificates of designation for the Series A Preferred Stock, the Series C Preferred Stock, the Series D Preferred Stock and the Series E Preferred Stock (the “Preferred Stock”) all prohibit the declaration or payment of dividends or distributions on common stock if dividends are not paid on the Preferred Stock, and the certificate of designations for the Series A Preferred Stock further prohibits the payment of dividends on the Series A Preferred Stock under certain circumstances. In addition, (i) MetLife, Inc.’s 6.40%Fixed-to-Floating Rate Junior Subordinated Debentures due 2066 (the “6.40% JSDs due 2066”), (ii) MetLife, Inc.’s 10.75%Fixed-to-Floating Rate Junior Subordinated Debentures due 2069 (the “10.75% JSDs due 2069”), (iii) upon an exchange of the 7.875%Fixed-to-Floating Rate Exchangeable Surplus Trust Securities of MetLife Capital Trust IV, the related 7.875%Fixed-to-Floating Rate Junior Subordinated Debentures due 2067 of MetLife, Inc. (the “7.875% JSDs due 2067”), and (iv) the 9.250%Fixed-to-Floating Rate Junior Subordinated Debentures due 2068 of MetLife, Inc. (the “9.25% JSDs due 2068”), all prohibit the declaration or payment of dividends or distributions on common stock under certain circumstances if interest is not paid in full on such securities, whether because of a mandatory or optional payment deferral, subject to certain exceptions.

Voting Rights. The holders of common stock are entitled to one vote per share on all matters on which the holders of common stock are entitled to vote and do not have any cumulative voting rights.

Liquidation and Dissolution. In the event of MetLife, Inc.’s liquidation, dissolution orwinding-up, the holders of common stock are entitled to share equally and ratably in MetLife, Inc.’s assets, if any, remaining after the payment of all of MetLife, Inc.’s liabilities and the liquidation preference of any outstanding class or series of preferred stock.

17

Other Rights. The holders of common stock have no preemptive, conversion, redemption or sinking fund rights. The holders of shares of MetLife, Inc.’s common stock are not required to make additional capital contributions.

Transfer Agent and Registrar. The transfer agent and registrar for MetLife, Inc.’s common stock is Computershare Inc. (successor in interest to Mellon Investor Services LLC).

Preferred Stock

General. MetLife, Inc.’s board of directors has the authority to issue preferred stock in one or more series and to fix the title and number of shares constituting any such series and the designations, powers, preferences, limitations and relative rights including offering price, any dividend rights (including whether dividends will be cumulative ornon-cumulative), dividend rate, voting rights, terms of any redemption, any redemption price or prices, conversion or exchange rights and any liquidation preferences of the shares constituting any series, without any further vote or action by stockholders. The specific terms of the preferred stock will be described in the prospectus supplement.

MetLife, Inc. has authorized 10,000,000 shares of Series A Junior Participating Preferred Stock for issuance in connection with a stockholder rights plan. The stockholder rights plan expired at the close of business on April 4, 2010 and was not renewed.

Voting Rights. The Delaware General Corporation Law provides that the holders of preferred stock will have the right to vote separately as a class on any proposal involving fundamental changes in the rights of holders of such preferred stock. The prospectus supplement will describe the voting rights, if any, of the preferred stock.

Conversion or Exchange. The prospectus supplement will describe the terms, if any, on which the preferred stock may be convertible into or exchangeable for securities described in this prospectus. These terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at MetLife, Inc.’s option. These provisions may set forth the conversion price, the method of determining the conversion price and the conversion period and may allow or require the number of shares of MetLife, Inc.’s common stock or other securities to be received by the holders of preferred stock to be adjusted.

Redemption. The prospectus supplement will describe the obligation, if any, to redeem the preferred stock in whole or in part at the times and at the redemption prices set forth in the applicable prospectus supplement.

Unless otherwise indicated in the applicable prospectus supplement, MetLife, Inc. may not purchase or redeem any of the outstanding shares or any series of preferred stock unless full cumulative dividends, if any, have been paid or declared and set apart for payment upon all outstanding shares of any series of preferred stock for all past dividend periods, and unless all of MetLife, Inc.’s matured obligations with respect to all sinking funds, retirement funds or purchase funds for all series of preferred stock then outstanding have been met.

Certain Provisions in MetLife, Inc.’s Amended and Restated Certificate of Incorporation, As Amended (the “Certificate of Incorporation”), and Amended and RestatedBy-Laws (the“By-Laws”) and in Delaware and New York Law

A number of provisions of MetLife, Inc.’s Certificate of Incorporation andBy-Laws deal with matters of corporate governance and rights of stockholders. The following discussion is a general summary of selected provisions of MetLife, Inc.’s Certificate of Incorporation andBy-Laws and regulatory provisions that might be deemed to have a potential “anti-takeover” effect. These provisions may have the effect of discouraging a future takeover attempt which is not approved by MetLife, Inc.’s board of directors but which individual stockholders may deem to be in their best interests or in which stockholders may receive a substantial premium for their shares

18

over then current market prices. As a result, stockholders who might desire to participate in such a transaction may not have an opportunity to do so. Such provisions will also render the removal of the incumbent board of directors or management more difficult. Some provisions of the Delaware General Corporation Law and the New York Insurance Law may also have an anti-takeover effect. The following description of selected provisions of MetLife, Inc.’s Certificate of Incorporation andBy-Laws and selected provisions of the Delaware General Corporation Law and the New York Insurance Law is necessarily general and reference should be made in each case to MetLife, Inc.’s Certificate of Incorporation andBy-Laws, which are incorporated by reference as exhibits to the registration statement of which this prospectus forms a part, and to the provisions of those laws.

Exercise of Duties by Board of Directors

MetLife, Inc.’s Certificate of Incorporation provides that while the MetLife Policyholder Trust (as described below) is in existence, each MetLife, Inc. director is required, in exercising his or her duties as a director, to take the interests of the trust beneficiaries into account as if they were holders of the shares of common stock held in the trust, except to the extent that any such director determines, based on advice of counsel, that to do so would violate his or her duties as a director under Delaware law.

Restriction on Maximum Number of Directors and Filling of Vacancies on MetLife, Inc.’s Board of Directors

Pursuant to MetLife, Inc.’sBy-Laws and subject to the rights of the holders of any class of preferred stock, the number of directors may be fixed from time to time exclusively by resolution adopted by a majority of the entire board of directors, but the board of directors will at no time consist of fewer than three directors. Stockholders may remove a director with or without cause at a meeting of the stockholders by a vote of a majority of the combined voting power of the outstanding stock entitled to vote generally in the election of directors, in which case the vacancy caused by such removal may be filled at such meeting by the stockholders entitled to vote for the election of the director so removed. Any vacancy on the board of directors, including a vacancy resulting from an increase in the number of directors or resulting from a removal where the stockholders have not filled the vacancy, subject to the rights of the holders of any class of preferred stock, may be filled by a majority of the directors then in office, although less than a quorum. These provisions give incumbent directors significant authority that may have the effect of limiting the ability of stockholders to effect a change in management.

Advance Notice Requirements for Nomination of Directors and Presentation of New Business at Meetings of Stockholders; Action by Written Consent

MetLife, Inc.’sBy-Laws provide for advance notice and other provisions in respect of stockholder proposals and nominations for director. In addition, pursuant to the provisions of both the Certificate of Incorporation and theBy-Laws, stockholder action may not be taken by written consent. Rather, any action taken by the stockholders must be effected at a duly called meeting. The chairman, the chief executive officer or the secretary pursuant to a board resolution or, under some circumstances, the president or a director who also is an officer, may call a special meeting. MetLife, Inc.’sBy-Laws also permit stockholders representing ownership of 25% or more of the combined voting power of the outstanding shares of common stock to call a special meeting of the stockholders, provided that the stockholders satisfy the requirements specified in theBy-Laws. These provisions make it more difficult for a stockholder to place a proposal or nomination on the meeting agenda and prohibit a stockholder from taking action without a meeting, and therefore may reduce the likelihood that a stockholder will seek to take independent action to replace directors or with respect to other matters that are not supported by management for stockholder vote.

Limitations on Director Liability

MetLife, Inc.’s Certificate of Incorporation contains a provision that is designed to limit the directors’ liability to the extent permitted by the Delaware General Corporation Law and any amendments to that law.

19

Specifically, directors will not be held liable to MetLife, Inc. or its stockholders for monetary damages for an act or omission in their capacity as a director, except for liability as a result of:

• a breach of the duty of loyalty to MetLife, Inc. or its stockholders;

• acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

• payment of an improper dividend or improper redemption or repurchase of MetLife, Inc.’s stock under Section 174 of the Delaware General Corporation Law; or

• any transaction from which the director received an improper personal benefit.

The principal effect of the limitation on liability provision is that a stockholder is unable to prosecute an action for monetary damages against a director of MetLife, Inc. unless the stockholder can demonstrate one of the specified bases for liability. This provision, however, does not eliminate or limit director liability arising in connection with causes of action brought under the federal securities laws. MetLife, Inc.’s Certificate of Incorporation also does not eliminate the directors’ duty of care. The inclusion of the limitation on liability provision in the certificate may, however, discourage or deter stockholders or management from bringing a lawsuit against directors for a breach of their fiduciary duties, even though such an action, if successful, might otherwise have benefited MetLife, Inc. and its stockholders. This provision should not affect the availability of equitable remedies such as injunction or rescission based upon a director’s breach of the duty of care.

MetLife, Inc.’sBy-Laws also provide that MetLife, Inc. will indemnify its directors and officers to the fullest extent permitted by Delaware law. MetLife, Inc. is required to indemnify its directors and officers for all judgments, fines, amounts paid in settlement, legal fees and other expenses reasonably incurred in connection with pending or threatened legal proceedings because of the director’s or officer’s position with MetLife, Inc. or another entity, including Metropolitan Life Insurance Company, that the director or officer serves at MetLife, Inc.’s request, subject to certain conditions, and to advance funds to MetLife, Inc.’s directors and officers to enable them to defend against such proceedings. To receive indemnification, the director or officer must succeed in the legal proceeding or act in good faith and in a manner reasonably believed to be in or not opposed to the best interests of MetLife, Inc. and with respect to any criminal action or proceeding, in a manner he or she reasonably believed to be lawful.

Business Combination Statute

In addition, as a Delaware corporation with a class of voting stock listed on a national securities exchange, MetLife, Inc. is subject to Section 203 of the Delaware General Corporation Law, unless it elects in its certificate of incorporation not to be governed by the provisions of Section 203. MetLife, Inc. has not made that election. Section 203 can affect the ability of an “interested stockholder” of MetLife, Inc. to engage in certain business combinations, including mergers, consolidations or acquisitions of additional shares of MetLife, Inc. for a period of three years following the time that the stockholder becomes an “interested stockholder.” An “interested stockholder” is defined to include any person owning, directly or indirectly, 15% or more of the outstanding voting stock of a corporation. The provisions of Section 203 are not applicable in some circumstances, including those in which (1) the business combination or transaction which results in the stockholder becoming an “interested stockholder” is approved by the corporation’s board of directors prior to the time the stockholder becomes an “interested stockholder” or (2) the “interested stockholder,” upon consummation of such transaction, owns at least 85% of the voting stock of the corporation outstanding prior to such transaction.

Restrictions on Acquisitions of Securities

The insurance laws and regulations of New York, the jurisdiction in which MetLife, Inc.’s principal insurance subsidiary, Metropolitan Life Insurance Company, is organized, may delay or impede a business combination involving MetLife, Inc. In addition to the limitations described in the immediately preceding

20

paragraph, the New York Insurance Law prohibits any person from acquiring control of Metropolitan Life Insurance Company, either directly or indirectly through any acquisition of control of MetLife, Inc., without the prior approval of the New York Superintendent of Financial Services. That law presumes that control exists where any person, directly or indirectly, owns, controls, holds the power to vote 10% or more of MetLife, Inc.’s outstanding voting stock, unless the New York Superintendent of Financial Services, upon application, determines otherwise. Even persons who do not acquire beneficial ownership of more than 10% of the outstanding shares of MetLife, Inc.’s common stock may be deemed to have acquired such control, if the New York Superintendent of Financial Services determines that such persons, directly or indirectly, exercise a controlling influence over MetLife, Inc.’s management or policies. Therefore, any person seeking to acquire a controlling interest in MetLife, Inc. would face regulatory obstacles which may delay, deter or prevent an acquisition.

The insurance holding company laws and other insurance laws of many other states also regulate changes of control (generally presumed upon acquisitions of 10% or more of voting securities) of domestic insurers (including insurers owned by MetLife, Inc.) and insurance holding companies such as MetLife, Inc.

MetLife Policyholder Trust

Under a plan of reorganization adopted in September 1999, Metropolitan Life Insurance Company converted from a mutual life insurance company to a stock life insurance company subsidiary of MetLife, Inc. The MetLife Policyholder Trust was established to hold the shares of common stock allocated to eligible policyholders. A total of 494,466,664 shares of common stock were distributed to the MetLife Policyholder Trust for the benefit of policyholders of Metropolitan Life Insurance Company on the effective date of the plan of reorganization. As of October 31, 2019, the trust held 141,740,537 shares of MetLife, Inc.’s common stock. Because of the number of shares held by the trust and the voting provisions of the trust, the trust may affect the outcome of matters brought to a stockholder vote.

The trustee will generally vote all of the shares of common stock held in the trust in accordance with the recommendations given by MetLife, Inc.’s board of directors to its stockholders or, if the board gives no such recommendation, as directed by the board, except on votes regarding certain fundamental corporate actions. As a result of the voting provisions of the trust, MetLife, Inc.’s board of directors will effectively be able to control votes on all matters submitted to a vote of stockholders, excluding those fundamental corporate actions described below, so long as the trust holds a substantial number of shares of MetLife, Inc.’s common stock.

If the vote relates to fundamental corporate actions specified in the trust, the trustee will solicit instructions from the beneficiaries and vote all shares held in the trust in proportion to the instructions it receives, which would give disproportionate weight to the instructions actually given by trust beneficiaries. These actions include:

• an election or removal of directors in which a stockholder has properly nominated one or more candidates in opposition to a nominee or nominees of MetLife, Inc.’s board of directors or a vote on a stockholder’s proposal to oppose a board nominee for director, remove a director for cause or fill a vacancy caused by the removal of a director by stockholders, subject to certain conditions;

• a merger or consolidation, a sale, lease or exchange of all or substantially all of the assets, or a recapitalization or dissolution of MetLife, Inc., in each case requiring a vote of MetLife, Inc.’s stockholders under applicable Delaware law;

• any transaction that would result in an exchange or conversion of shares of common stock held by the trust for cash, securities or other property; and

• any proposal requiring MetLife, Inc.’s board of directors to amend or redeem the rights under the stockholder rights plan, other than a proposal with respect to which MetLife, Inc. has received advice of nationally-recognized legal counsel to the effect that the proposal is not a proper subject for stockholder action under Delaware law.

21

DESCRIPTION OF DEPOSITARY SHARES

The following outlines some of the general terms and provisions of the depositary shares. Further terms of the depositary shares and the applicable deposit agreement will be stated in the applicable prospectus supplement. The following description and any description of the depositary shares in a prospectus supplement may not be complete and is subject to and qualified in its entirety by reference to the terms and provisions of the deposit agreement, a form of which has been or will be filed as an exhibit to the registration statement of which this prospectus forms a part.

The particular terms of the depositary shares offered by any prospectus supplement and the extent to which the general provisions described below may apply to such depositary shares will be outlined in the applicable prospectus supplement.

General

MetLife, Inc. may choose to offer fractional interests in debt securities or fractional shares of common stock or preferred stock. MetLife, Inc. may issue fractional interests in debt securities, common stock or preferred stock, as the case may be, in the form of depositary shares. Each depositary share would represent a fractional interest in a security of a particular series of debt securities or a fraction of a share of common stock or of a particular series of preferred stock, as the case may be, and would be evidenced by a depositary receipt.

MetLife, Inc. will deposit the debt securities or shares of common stock or preferred stock represented by depositary shares under a deposit agreement between MetLife, Inc. and a depositary which will be named in the applicable prospectus supplement. Subject to the terms of the deposit agreement, as an owner of a depositary share, you will be entitled, in proportion to the applicable fraction of a debt security or share of common stock or preferred stock represented by the depositary share, to all the rights and preferences of the debt security, common stock or preferred stock, as the case may be, represented by the depositary share, including, as the case may be, interest, dividend, voting, conversion, redemption, sinking fund, repayment at maturity, subscription and liquidation rights.

Interest, Dividends and Other Distributions

The depositary will distribute all payments of interest, cash dividends or other cash distributions received on the debt securities, common stock or preferred stock, as the case may be, to you in proportion to the number of depositary shares that you own. In the event of a distribution other than in cash, the depositary will distribute property received by it to you in an equitable manner, unless the depositary determines that it is not feasible to make a distribution. In that case, the depositary may sell the property and distribute the net proceeds from the sale to you.

Redemption of Depositary Shares

If a debt security, common stock or series of preferred stock represented by depositary shares is redeemed, the depositary will redeem your depositary shares from the proceeds received by the depositary resulting from the redemption. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per debt security or share of common stock or preferred stock, as the case may be, payable in relation to the redeemed series of debt securities, common stock or preferred stock. Whenever MetLife, Inc. redeems debt securities or shares of common stock or preferred stock held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing, as the case may be, fractional interests in the debt securities or shares of common stock or preferred stock redeemed. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot, proportionately or by any other equitable method as the depositary may determine.

22

Exercise of Rights under the Indentures or Voting the Common Stock or Preferred
