That prospectus supplement may include a discussion of any risk factors or other special considerations applicable to those securities. The prospectus supplement also may add, update or change information in this prospectus. If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the information in the prospectus supplement.

SPECIAL NOTE ON FORWARD-LOOKING INFORMATION

This prospectus and any accompanying prospectus supplement and the documents incorporated herein and therein by reference contain statements that are forward-looking. Statements that are not historical facts, including statements about our beliefs and expectations, are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We want to caution readers that these statements may change based on various factors, and are subject to known and unknown risks and uncertainties. These forward-looking statements are based on current expectations and assumptions that are subject to risks and uncertainties and actual results could differ materially. Words such as “estimate,” “target,” “project,” “plan,” “believe,” “expect,” “anticipate,” “intend” and similar expressions may identify such forward-looking statements. Forward-looking statements speak only as of the date they are made, and we undertake no obligation to update or revise any such statements or release publicly any revisions to these forward-looking statements to reflect new information, events or circumstances after the date of this prospectus or the occurrence of unanticipated events, except as required by law or regulation. Forward-looking statements are not guarantees of future performance. They involve risks, uncertainties and assumptions. Our future performance and actual results may differ materially from those expressed in forward-looking statements. Many of the factors that will determine these results are beyond our ability to control or predict. Accordingly, you should not place undue reliance on forward-looking statements, which speak only as of, and are based on information available to us on, the date of the applicable document. All subsequent written and oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section.

A detailed discussion of the factors that could cause actual results to differ materially from our published expectations is contained under the heading “Risk Factors” in our filings with the SEC, including our Annual Report on Form 10-K for the fiscal year ended December 31, 2017, and any other reports we file with the SEC in the future, which are incorporated by reference into this prospectus.

THE COMPANY

Horace Mann Educators Corporation (“HMEC”; and together with its subsidiaries, the “Company” or “Horace Mann”) is an insurance holding company incorporated in Delaware. Through its subsidiaries, HMEC markets and underwrites personal lines of property and casualty (primarily personal lines of automobile and property) insurance, retirement products (primarily tax-qualified annuities) and life insurance in the United States of America (“U.S.”). HMEC’s principal insurance subsidiaries are Horace Mann Life Insurance Company, Horace Mann Insurance Company, Horace Mann Property & Casualty Insurance Company and Teachers Insurance Company, each of which is an Illinois corporation, and Horace Mann Lloyds, an insurance company domiciled in Texas.

Founded by Educators for Educators^®, we market our products primarily to K-12 teachers, administrators and other employees of public schools and their families. Our nearly one million customers typically have moderate annual incomes, with many belonging to two-income households. Their financial planning tends to focus on retirement, security, savings and primary insurance needs. Management believes that Horace Mann is the largest national multiline insurance company focused on the nation’s educators as its primary market.

We market and service our products primarily through a dedicated sales force of full-time Exclusive Distributors supported by the Company’s Customer Contact Center. These agents sell Horace Mann’s products and limited additional third-party vendor products. Some of these agents are former educators or individuals with close ties to the educational community who utilize their contacts within, and knowledge of, the target market. This dedicated agent sales force is supplemented by an independent agent distribution channel for our retirement products.

We conduct and manage our business through four segments. The three operating segments, representing the major lines of insurance business, are: property and casualty insurance, retirement products, and life insurance. We do not allocate the impact of corporate-level transactions to the operating segments, consistent with the basis for management’s evaluation of the results of those segments, but classify those items in the fourth segment, corporate and other.

We are one of the largest participants in the K-12 educator portion of the 403(b) tax-qualified annuity market, measured by 403(b) net written premium on a statutory accounting basis. Our 403(b) tax-qualified annuities are voluntarily purchased by individuals employed by public school systems or other tax-exempt organizations through the employee benefit plans of those entities. We have 403(b) payroll deduction capabilities utilized by approximately 30% of the 13,600 public school districts in the U.S.

Our headquarters are located at 1 Horace Mann Plaza, Springfield, Illinois 62715-0001, and our telephone number is 217-789-2500. We maintain a Web site at http://www.horacemann.com. Information on our Web site is not incorporated by reference and is not a part of this prospectus or any accompanying prospectus supplement.

The following table sets forth our ratios of earnings to fixed charges on a consolidated basis for the years ended December 31, 2017, 2016, 2015, 2014 and 2013.

DESCRIPTION OF THE DEBT SECURITIES

The following is a general description of the debt securities that we may offer from time to time. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which the general provisions described below may apply to those securities, will be described in the applicable prospectus supplement. We may also sell hybrid securities that combine certain features of debt securities and other securities described in this prospectus. As you read this section, please remember that the specific terms of a debt security as described in the applicable prospectus supplement will supplement and may modify or replace the general terms described in this section. If there are any differences between the applicable prospectus supplement and this prospectus, the applicable prospectus supplement will control. As a result, the statements we make in this section may not apply to the debt security you purchase.

As used in this “Description of the Debt Securities,” the “Company” refers to Horace Mann Educators Corporation and does not, unless the context otherwise indicates, include our subsidiaries.

Capitalized terms used but not defined in this section have the respective meanings set forth in the applicable indenture.

General

The debt securities that we offer will be either senior debt securities or subordinated debt securities. We will issue senior debt securities under an Indenture, dated as of November 23, 2015, by and between us and The Bank of New York Mellon Trust Company, N.A., as trustee, which we refer to as the senior indenture, and such trustee, the senior trustee. We will issue subordinated debt securities under a different indenture, which we refer to as the subordinated indenture, to be entered into between us and the trustee named in the applicable prospectus supplement. We refer to both the senior indenture and the subordinated indenture as the indentures, and to each of the trustees under the indentures as a trustee. In addition, the indentures may be supplemented or amended as necessary to set forth the terms of the debt securities issued under the indentures. You should read the indentures, including any amendments or supplements thereto, carefully to fully understand the terms of the debt securities. The senior indenture and the form of subordinated indenture have been filed as exhibits to the registration statement of which this prospectus is a part. The indentures are subject to, and are governed by, the Trust Indenture Act of 1939, as amended.

The senior debt securities will be unsubordinated obligations of the Company. They will rank equally with each other and all of our other unsubordinated debt, unless otherwise indicated in the applicable prospectus supplement. The subordinated debt securities will be subordinated in right of payment to the prior payment in full of our senior debt. See “Subordination of Subordinated Debt Securities.” The subordinated debt securities will rank equally with each other, unless otherwise indicated in the applicable prospectus supplement. We will indicate in each applicable prospectus supplement, as of the most recent practicable date, the aggregate amount of our outstanding debt that would rank senior to the subordinated debt securities.

Unless otherwise provided in the prospectus supplement relating to any debt securities, the debt securities will not constitute obligations of our subsidiaries. Creditors of our subsidiaries are entitled to a claim on the assets of those subsidiaries. Consequently, in the event of a liquidation or reorganization of any subsidiary, creditors of the subsidiary are likely to be paid in full before any distribution is made to the Company and holders of debt securities, except to the extent that the Company is itself recognized as a creditor of such subsidiary, in which case the Company’s claims would still be subordinate to any security interests in the assets of such subsidiary and any debt of such subsidiary senior to that held by the Company.

The indentures do not limit the amount of debt securities that can be issued thereunder and provide that debt securities of any series may be issued thereunder up to the aggregate principal amount that we may authorize from time to time. Unless otherwise provided in any prospectus supplement, the indentures do not limit the

7

amount of other indebtedness or securities that we may issue. We may issue debt securities of the same series at more than one time and, unless prohibited by the terms of the series, we may reopen a series for issuances of additional debt securities, without the consent of the holders of the outstanding debt securities of that series. All debt securities issued as a series, including those issued pursuant to any reopening of a series will vote together as a single class unless otherwise described in the prospectus supplement for such series.

Reference is made to the prospectus supplement for the following and other possible terms of each series of the debt securities in respect of which this prospectus is being delivered:

(1) the title of the debt securities (including CUSIP numbers);

(2) any limit upon the aggregate principal amount of the debt securities;

(3) if other than 100% of the principal amount, the percentage of their principal amount at which the debt securities will be offered;

(4) the date or dates on which the principal of the debt securities will be payable (or method of determination thereof);

(5) the rate or rates (or method of determination thereof) at which the debt securities will bear interest, if any, the date or dates from which any such interest will accrue and on which such interest will be payable, and the record dates for the determination of the holders to whom interest is payable;

(6) if other than as set forth herein, the place or places where the principal of and interest, if any, on the debt securities will be payable;

(7) the price or prices at which, the period or periods within which and the terms and conditions upon which debt securities may be redeemed, in whole or in part, at our option;

(8) if other than the principal amount thereof, the portion of the principal amount of the debt securities payable upon declaration of acceleration of the maturity thereof;

(9) our obligation, if any, to redeem, repurchase or repay debt securities, whether pursuant to any sinking fund or analogous provisions or pursuant to other provisions set forth therein or at the option of a holder thereof;

(10) the denominations in which securities of the series shall be issuable;

(11) the form of such debt securities, including such legends as required by law or as we deem necessary or appropriate;

(12) whether the debt securities are convertible into our common stock and, if so, the terms and conditions of such conversion;

(13) whether there are any authentication agents, paying agents, transfer agents or registrars with respect to the debt securities;

(14) whether the debt securities will be represented in whole or in part by one or more global notes registered in the name of a depositary or its nominee;

(15) the ranking of such debt securities as senior debt securities or subordinated debt securities;

(16) if other than U.S. dollars, the currency or currencies (including composite currencies or currency units) in which the debt securities may be purchased and in which payments on the debt securities will be made (which currencies may be different for payments of principal, premium or other amounts, if any, and/or interest, if any);

8

(17) if the debt securities will be secured by any collateral, a description of the collateral and the terms and conditions of the security and realization provisions;

(18) the provisions relating to any guarantee of the debt securities, including the ranking thereof;

(19) the ability, if any, to defer payments of principal, interest, or other amounts; and

(20) any other terms or conditions not inconsistent with the provisions of the indenture under which the debt securities will be issued.

“Principal” when used herein includes any premium on any series of the debt securities.

Unless otherwise provided in the prospectus supplement relating to any debt securities, principal and interest, if any, will be payable, and transfers of the debt securities may be registered, at the office or offices or agency we maintain for such purposes. Interest on the debt securities will be payable on any interest payment date to the persons in whose names the debt securities are registered at the close of business on the record date for such interest payment.

The debt securities may be represented in whole or in part by one or more global notes registered in the name of a depositary or its nominee and, if so represented, interests in such global note will be shown on, and transfers thereof will be effected only through, records maintained by the designated depositary and its participants.

Unless otherwise provided in the prospectus supplement relating to any debt securities, the debt securities may be exchanged for an equal aggregate principal amount of debt securities of the same series and date of maturity in such authorized denominations as may be requested upon surrender of the debt securities at an agency of the Company maintained for such purpose and upon fulfillment of all other requirements of such agent. No service charge will be made for any registration of transfer or exchange of the debt securities, but we may require payment of an amount sufficient to cover any tax or other governmental charge payable in connection therewith.

The indentures require the annual filing by the Company with the trustee of a certificate as to knowledge of any default with respect to debt securities of any series during the preceding year.

We will comply with Section 14(e) under the Exchange Act, to the extent applicable, and any other tender offer rules under the Exchange Act that may then be applicable, in connection with any obligation to purchase debt securities at the option of the holders thereof. Any such obligation applicable to a series of debt securities will be described in the prospectus supplement relating thereto.

Unless otherwise described in a prospectus supplement relating to any debt securities, there are no covenants or provisions contained in the indentures that may afford the holders of debt securities protection in the event that we enter into a highly leveraged transaction.

The statements made hereunder relating to the indentures and the debt securities are summaries of certain provisions thereof and are qualified in their entirety by reference to all provisions of the indentures and the debt securities and the descriptions thereof, if different, in the applicable prospectus supplement.

Events of Default

Except as otherwise set forth in any prospectus supplement relating to any debt securities, an Event of Default with respect to the debt securities of any series is defined in the indentures as:

(1) default in the payment of any installment of interest upon any of the debt securities of such series as and when the same shall become due and payable, and continuance of such default for a period of 30 days;

9

(2) default in the payment of all or any part of the principal of any of the debt securities of such series as and when the same shall become due and payable either at maturity, upon any redemption or repurchase, by declaration or otherwise;

(3) default in the performance, or breach, of any other covenant or warranty contained in the debt securities of such series or set forth in the applicable indenture (other than a covenant or warranty included in the applicable indenture solely for the benefit of one or more series of debt securities other than such series) and continuance of such default or breach for a period of 90 days after due notice by the trustee or by the holders of at least 25% in principal amount of the outstanding securities of such series; or

(4) certain events of bankruptcy, insolvency or reorganization of the Company.

Additional Events of Default may be added for the benefit of holders of certain series of debt securities that, if added, will be described in the prospectus supplement relating to such debt securities.

The indentures provide that the trustee shall notify the holders of debt securities of each series of any continuing default known to the trustee which has occurred with respect to such series within 90 days after the occurrence thereof. The indentures provide that notwithstanding the foregoing, except in the case of default in the payment of the principal of, premium, if any, or interest on any of the debt securities of such series, including payments pursuant to the redemption provisions of the debt securities of such series, if any, the trustee may withhold such notice if the trustee in good faith determines that the withholding of such notice is in the interests of the holders of debt securities of such series.

Except as otherwise set forth in the prospectus supplement relating to any debt securities, the indentures provide that if an Event of Default (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganizations of the Company) with respect to any series of debt securities shall have occurred and be continuing, either the trustee or the holders of at least 25% in aggregate principal amount of debt securities of such series then outstanding may declare the principal amount of all debt securities of such series and any accrued and unpaid interest through the date of such declaration to be due and payable immediately, but upon certain conditions such declaration may be annulled. In the case of certain events of bankruptcy, insolvency or reorganization, the principal amount of the debt securities and any unpaid interest accrued thereon through the occurrence of such event shall automatically become and be immediately due and payable. Any past defaults and the consequences thereof, except a default in the payment of principal of or interest, if any, on debt securities of such series, may be waived by the holders of a majority in principal amount of the debt securities of such series then outstanding.

Subject to the provisions of the indentures relating to the duties of the trustee, in case an Event of Default with respect to any series of debt securities shall occur and be continuing, the trustee shall not be under any obligation to exercise any of the trusts or powers vested in it by the indentures at the request or direction of any of the holders of such series, unless such holders shall have offered to such trustee security or indemnity satisfactory to it. The holders of a majority in aggregate principal amount of the debt securities of each series affected and then outstanding shall have the right, subject to certain limitations, to direct the time, method and place of conducting any proceeding for any remedy available to the trustee under the applicable indenture or exercising any trust or power conferred on the trustee with respect to the debt securities of such series; provided that the trustee may refuse to follow any direction which is in conflict with any law or such indenture or supplemental indenture and subject to certain other limitations.

No holder of any debt security of any series will have any right under the indentures to institute any proceeding with respect to the indentures or for any remedy thereunder, unless such holder shall have previously given the trustee written notice of an Event of Default with respect to debt securities of such series and unless the holders of at least 25% in aggregate principal amount of the outstanding debt securities of such series shall also have made written request, and offered indemnity satisfactory to the trustee to institute the proceeding, and the

10

trustee shall have failed to institute the proceeding within 60 days after its receipt of such request, and the trustee shall not have received from the holders of a majority in aggregate principal amount of the outstanding debt securities of such series a direction inconsistent with such request. However, the right of a holder of any debt security to receive payment of the principal of and interest, if any, on such debt security on or after the due dates expressed in such debt security, or to institute suit for the enforcement of any such payment on or after such dates, shall not be impaired or affected without the consent of such holder.

Merger

Except as otherwise set forth in any prospectus supplement relating to any debt securities, the Company may consolidate with, sell, convey or lease all or substantially all of its assets to, or merge with or into, any other corporation, if:

(1) either (a) the Company is the continuing corporation or (b) the successor corporation is a domestic corporation and expressly assumes the due and punctual payment of the principal of and interest on all the debt securities outstanding under such indenture and the due and punctual performance and observance of all of the covenants and conditions of such indenture to be performed or observed by the Company; and

(2) the Company or such successor corporation, as the case may be, is not, immediately after such merger, consolidation, sale, conveyance or lease, in material default in the performance or observance of any such covenant or condition.

Satisfaction and Discharge of Indentures

Except as otherwise set forth in any prospectus supplement relating to any debt securities, the indenture with respect to any series of debt securities (except for certain specified surviving obligations including the Company’s obligation to pay the principal of and interest on the debt securities of such series) will be discharged and cancelled upon the satisfaction of certain conditions, including when the outstanding debt securities of such series have been cancelled or delivered for cancellation or have become due and payable or will become due and payable within one year, and we deposit with the trustee under such indenture cash or appropriate government obligations or a combination thereof sufficient for such payment or redemption in accordance with the applicable indenture and the terms of the debt securities of such series.

Modification of the Indentures

Except as otherwise set forth in any prospectus supplement relating to any debt securities, the indentures contain provisions permitting the Company and the trustee thereunder, with the consent of the holders of not less than a majority in aggregate principal amount of the debt securities of each series at the time outstanding under the applicable indenture affected thereby, to execute supplemental indentures adding any provisions to, or changing in any manner or eliminating any of the provisions of, the applicable indenture or any supplemental indenture or modifying in any manner the rights of the holders of the debt securities of each such series; provided that no such supplemental indenture may:

(1) extend the final maturity date of any debt security, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of any interest thereon, or reduce any amount payable on redemption or repurchase thereof, change the time at which the debt securities of any series may be redeemed, or impair or affect the right of any holder of debt securities to institute suit for payment thereof or, if the debt securities provide therefor, any right of repayment at the option of the holders of the debt securities;

11

(2) reduce the aforesaid percentage of debt securities of such series, the consent of the holders of which is required for any such supplemental indenture, without the consent of the holders of all debt securities of such series so affected; or

(3) reduce the amount of principal payable upon acceleration of the maturity date of any original issue discount security.

Additional amendments requiring the consent of each holder affected thereby may be specified for the benefit of holders of certain series of debt securities and, if added, will be described in the prospectus supplement relating to such debt securities.

Additionally, in certain circumstances prescribed in the indenture governing the relevant series of debt securities, the Company and the trustee may execute supplemental indentures without the consent of the holders of debt securities.

Defeasance

The indentures provide, unless otherwise provided with respect to the debt securities of any series, that the Company may elect to terminate, and be deemed to have satisfied, all its obligations with respect to such debt securities (“legal defeasance”) or all of its obligations with respect to punctual payment of principal of, and interest, if any on all debt securities of such series when due, the maintenance of an office or agency in respect of such debt securities, the appointment of a paying agent, annual compliance certificates and calculation of original issue discount, if any (“covenant defeasance”) (except in the case of either legal defeasance or covenant defeasance for the obligations to register the transfer or exchange of such debt securities, to replace mutilated, destroyed, lost or stolen debt securities and to compensate and indemnify the trustee) upon the deposit with the trustee, in trust for such purpose, of funds and/or government obligations which through the payment of principal and interest in accordance with their terms will provide funds in an amount sufficient to pay the principal of and premium and interest, if any, on the outstanding debt securities of such series, on the scheduled due dates therefor. Such a trust may be established only if, the Company complies with certain conditions, including, in the case of covenant defeasance, delivery to the trustee of an opinion of counsel to the effect that, subject to customary assumptions and exclusions, the holders of such debt securities will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred, or, in the case of legal defeasance, delivery to the applicable trustee of an opinion of counsel stating that (1) we have received from, or there has been published by, the Internal Revenue Service a ruling, or (2) since the date of the respective indenture there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the holders of such debt securities will not recognize income, gain or loss for federal income tax purposes as a result of such deposit and defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred.

The prospectus supplement may further describe these or other provisions, if any, permitting defeasance with respect to the debt securities of any series.

In addition, the senior indenture provides that, in order to comply with applicable tax laws, we must provide the senior trustee sufficient information about holders of our debt securities or other applicable parties or transactions so that the senior trustee may determine whether it has tax related obligations under applicable law, subject to certain exceptions. Under the terms of the senior indenture, the senior trustee is entitled to make any withholding or deduction from payments to the extent necessary to comply with applicable law.

Subordination of Subordinated Debt Securities

The senior debt securities will constitute part of our Senior Indebtedness (as defined below) and will rank pari passu with all outstanding senior debt. Except as set forth in the related prospectus supplement, the

12

subordinated debt securities will be subordinated, in right of payment, to the prior payment in full of our Senior Indebtedness, including the senior debt securities, whether outstanding at the date of the subordinated indenture or thereafter incurred, assumed or guaranteed.

Except as set forth in the related prospectus supplement, “Senior Indebtedness” means:

(1) the principal of and premium, if any, and unpaid interest on indebtedness for money borrowed;

(2) purchase money and similar obligations;

(3) obligations under capital leases or leases of property or assets made as part of any sale and leaseback transaction;

(4) guarantees, assumptions or purchase commitments relating to, or other transactions as a result of which the Company is responsible for the payment of, such indebtedness of others;

(5) renewals, extensions and refunding of any such indebtedness;

(6) interest or obligations in respect of any such indebtedness accruing after the commencement of any insolvency or bankruptcy proceedings;

(7) obligations associated with derivative products such as interest rate and currency exchange contracts, foreign exchange contracts, commodity contracts, and similar arrangements;

unless, in each case, the instrument by which the Company incurred, assumed or guaranteed the indebtedness or obligations described in clauses (1) through (7) hereof expressly provides that such indebtedness or obligation is not senior in right of payment to the subordinated debt securities.

Upon any distribution of the Company’s assets in connection with any dissolution, winding up, liquidation or reorganization of the Company, whether in a bankruptcy, insolvency, reorganization or receivership proceeding or upon an assignment for the benefit of creditors or any other marshaling of the Company’s assets and liabilities or otherwise, except a distribution in connection with a merger or consolidation or a conveyance or transfer of all or substantially all of the properties of the Company in accordance with the subordinated indenture, the holders of all Senior Indebtedness shall first be entitled to receive payment of the full amount due thereon before the holders of any of the subordinated debt securities are entitled to receive any payment in respect of the subordinated debt securities. In the event that a payment default shall have occurred and be continuing with respect to the Senior Indebtedness, the holders of all Senior Indebtedness shall first be entitled to receive payment of the full amount due thereon before the holders of any of the subordinated debt securities are entitled to receive any payment in respect of the subordinated debt securities. In the event that the principal of the subordinated debt securities of any series shall have been declared due and payable pursuant to the subordinated indenture and such declaration shall not have been rescinded and annulled, the holders of all Senior Indebtedness outstanding at the time of such declaration shall first be entitled to receive payment of the full amount due thereon, or provision shall be made for such payment in full, before the holders of any of the subordinated debt securities are entitled to receive any payment in respect of the subordinated debt securities.

This subordination will not prevent the occurrence of any event of default with respect to the subordinated debt securities. There is no limitation on the issuance of additional Senior Indebtedness in the subordinated indenture.

Book-Entry, Delivery and Form

The debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary (a “Debt Depositary”) identified in the applicable

13

prospectus supplement. Global securities may be issued in either registered or bearer form and in either temporary or permanent form. Unless otherwise provided in such prospectus supplement, debt securities that are represented by a global security will be issued in denominations of $1,000 or any integral multiple thereof and will be issued in registered form only, without coupons.

We anticipate that any global securities will be deposited with, or on behalf of, The Depository Trust Company (“DTC”), and that such global securities will be registered in the name of Cede & Co., DTC’s nominee. We further anticipate that the following provisions will apply to the depository arrangements with respect to any such global securities. Any additional or differing terms of the depository arrangements will be described in the prospectus supplement relating to a particular series of debt securities issued in the form of global securities.

Beneficial interests in the global securities will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct or indirect participants in DTC. Investors may elect to hold their interests in the global securities through either DTC (in the United States) or (in Europe) through Clearstream Banking S.A. (“Clearstream”) or through the Euroclear system (“Euroclear”) of Euroclear S.A./N.V. Investors may hold their interests in the global securities directly if they are participants of such systems, or indirectly through organizations that are participants in these 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 U.S. depositaries, which in turn will hold these interests in customers’ securities accounts in the depositaries’ names on the books of DTC. Except as set forth below, the global securities may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee.

Debt securities represented by a global security can be exchanged for definitive securities in registered form only if:

A global security that can be exchanged as described in the preceding sentence will be exchanged for definitive securities issued in authorized denominations in registered form for the same aggregate amount. The definitive securities will be registered in the names of the owners of the beneficial interests in the global security as directed by DTC.

Beneficial interests in global securities will also be exchangeable for individual securities in certificated form in the event of a default or an event of default upon prior written notice to the trustee by or on behalf of DTC or at the written request of the owner of such beneficial interests.

We will make principal and interest payments on all debt securities represented by a global security to the paying agent which in turn will make payment to DTC or its nominee, as the case may be, as the sole registered owner and the sole holder of the debt securities represented by a global security for all purposes under the indenture. Accordingly, we, the trustee and any paying agent will have no responsibility or liability for:

14

DTC has advised us that its current practice is to credit participants’ accounts on each payment date with payments in amounts proportionate to their respective beneficial interests in the principal amount of such global security as shown on DTC’s records, upon DTC’s receipt of funds and corresponding detail information. The underwriters or agents for the debt securities represented by a global security will initially designate the accounts to be credited. Payments by participants to owners of beneficial interests in a global security will be governed by standing instructions and customary practices, as is the case with securities held for customer accounts registered in “street name,” and will be the sole responsibility of those participants. Book-entry notes may be more difficult to pledge because of the lack of a physical note.

DTC

So long as DTC or its nominee is the registered owner of a global security, DTC or its nominee, as the case may be, will be considered the sole owner and holder of the debt securities represented by that global security for all purposes of the debt securities. Owners of beneficial interests in the debt securities will not be entitled to have debt securities registered in their names, will not receive or be entitled to receive physical delivery of the debt securities in definitive form, any notices will be given only to DTC, and will not be considered owners or holders of debt securities under the indenture. Accordingly, each person owning a beneficial interest in a global security must rely on the procedures of DTC and, if that person is not a DTC participant, on the procedures of the participant through which that person owns its interest, to exercise any rights of a holder of debt securities. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of the securities in certificated form. These laws may impair the ability to transfer beneficial interests in a global security. Beneficial owners may experience delays in receiving distributions on their debt securities since distributions will initially be made to DTC and must then be transferred through the chain of intermediaries to the beneficial owner’s account.

We understand that, under existing industry practices, if we request holders to take any action, or if an owner of a beneficial interest in a global security desires to take any action which a holder is entitled to take under the indenture, then DTC would authorize the participants holding the relevant beneficial interests to take that action and those participants would authorize the beneficial owners owning through such participants to take that action or would otherwise act upon the instructions of beneficial owners owning through them.

Beneficial interests in a global security will be shown on, and transfers of those ownership interests will be effected only through, records maintained by DTC and its participants for that global security. The conveyance of notices and other communications by DTC to its participants and by its participants to owners of beneficial interests in the debt securities will be governed by arrangements among them, subject to any statutory or regulatory requirements in effect.

DTC has advised us that it 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 under the Exchange Act.

DTC holds the securities of its participants and facilitates the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of its participants. The electronic book-entry system eliminates the need for physical certificates. DTC’s participants include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and certain other organizations, some of which, and/or their representatives, own DTC. Banks, brokers, dealers, trust

15

companies and others that clear through or maintain a custodial relationship with a participant, either directly or indirectly, also have access to DTC’s book-entry system. The rules applicable to DTC and its participants are on file with the SEC.

DTC has advised us that the above information with respect to DTC has been provided to its participants and other members of the financial community for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind.

Clearstream

Clearstream has advised us that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations, or Clearstream Participants, and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry changes in accounts of Clearstream Participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream Participants, 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. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission 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 certain other organizations. Clearstream’s U.S. Participants are limited to securities brokers and dealers and banks. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant either directly or indirectly.

Distributions with respect to debt securities held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures, to the extent received by the U.S. Depositary for Clearstream.

Euroclear

Euroclear has advised us that it was created to hold securities for participants of Euroclear, or Euroclear Participants, and to clear and settle transactions between 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 performs various other services, including securities lending and borrowing and interacts with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A/N.V., or the Euroclear Operator, under contract with Euroclear plc, a U.K. corporation. All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not Euroclear plc. Euroclear plc establishes policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants include banks, including central banks, securities brokers and dealers and other professional financial intermediaries. 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.

The Euroclear Operator is a Belgian bank. As such it is regulated by the Belgian Banking and Finance Commission.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law, herein the Terms and Conditions. The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution

16

of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants, and has no record of or relationship with persons holding through Euroclear Participants.

Distributions with respect to debt securities held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Terms and Conditions, to the extent received by the U.S. Depositary for Euroclear.

Euroclear has further advised us that investors that acquire, hold and transfer interests in the debt securities by book-entry through accounts with the Euroclear Operator or any other securities intermediary are subject to the laws and contractual provisions governing their relationship with their intermediary, as well as the laws and contractual provisions governing the relationship between such an intermediary and each other intermediary, if any, standing between themselves and the global securities.

Global Clearance and Settlement Procedures

Initial settlement for the debt securities will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds using DTC’s Same-Day Funds Settlement System. 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 through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by its 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 its U.S. Depositary to take action to effect final settlement on its behalf by delivering or receiving debt securities through DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream Participants and Euroclear Participants may not deliver instructions directly to their respective U.S. Depositaries.

Because of time-zone differences, credits of debt securities received through Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in such debt securities settled during such processing will be reported to the relevant Euroclear Participants or Clearstream Participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of debt securities 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.

If the debt securities are cleared only through Euroclear and Clearstream (and not DTC), you will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers, exchanges, notices, and other transactions involving any securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers, and other institutions are open for business in the United States. In addition, because of time-zone differences, U.S. investors who hold their interests in the securities through these systems and wish to transfer their interests, or to receive or make a payment or delivery or exercise any other right with respect to their interests, on a particular day may find that the transaction will not be effected until the next business day in Luxembourg or Brussels, as applicable. Thus, U.S. investors who wish to exercise rights that expire on a particular day may need to act before the expiration date.

17

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of debt securities 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 modified or discontinued at any time. Neither we nor any paying agent will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective direct or indirect participants of their obligations under the rules and procedures governing their operations.

DESCRIPTION OF CAPITAL STOCK

General

Our authorized capital stock consists of 75,000,000 shares of common stock, $0.001 par value per share, and 1,000,000 shares of preferred stock, $0.001 par value per share. As of February 15, 2018, there were 40,780,247 shares of common stock and no shares of preferred stock outstanding.

The following descriptions are summaries of the material terms of our capital stock. You should refer to the applicable provisions of the Delaware General Corporation Law, our certificate of incorporation, our bylaws and the applicable prospectus supplement for additional information about our capital stock. See “Where You Can Find More Information.”

Common Stock

The holders of common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders. There is no cumulative voting for election of directors. Accordingly, the holders of a majority of the shares voted can elect all of the nominees for director. Our common stock is listed on the New York Stock Exchange under the symbol “HMN.”

Subject to preferences that may be applicable to any outstanding shares of preferred stock, the holders of our common stock are entitled to receive ratably those dividends when, as and if declared by our board of directors out of funds legally available for that purpose. Upon our liquidation, dissolution or winding up, subject to preferences that may be applicable to any outstanding preferred stock, the holders of our common stock are entitled to share ratably in all assets remaining or distributions to stockholders after payment of liabilities and the liquidation preferences of any outstanding shares of preferred stock. Our common stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to our common stock. All outstanding shares of our common stock are fully paid and nonassessable.

Limitations on Liability and Indemnification of Officers and Directors

Our amended and restated certificate of incorporation provides that, to the fullest extent permitted by Delaware law, none of our directors will be personally liable to us or to our stockholders for monetary damages for breach of fiduciary duties. The provision effectively eliminates our rights and the rights of our stockholders to recover monetary damages against a director for breach of fiduciary duty as a director. This provision does not, however, exonerate directors from liability under federal securities laws or for (1) breach of a director’s duty of loyalty to us or to our stockholders, (2) acts or omissions not in good faith or that involve intentional misconduct or knowing violation of law, (3) specified willful or negligent acts relating to the payment of dividends or the repurchase or redemption of securities or (4) any transaction from which a director has derived an improper personal benefit. Our by-laws further provide for indemnification of our officers and directors.

Delaware Business Combination Statute

We are subject to Section 203 of the Delaware General Corporation Law, an anti-takeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years following the date the person became an interested stockholder, unless the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Generally, a “business combination” includes a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. Generally, an “interested stockholder” is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own, 15% or more of a corporation’s voting stock. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance

19

by the board of directors, including discouraging attempts that might result in a premium over the market price for the shares of common stock held by stockholders. If any person acquires 15% or more of our outstanding stock, that person will be subject to the provisions of Section 203.

Transfer Agent and Registrar

American Stock Transfer & Trust Company is the transfer agent and registrar for our common stock. We will designate the transfer agent for each series of preferred stock in the applicable prospectus supplement.

DESCRIPTION OF OTHER SECURITIES

We will set forth in the applicable prospectus supplement a description of any preferred stock, depositary shares, warrants, delayed delivery contracts or units that may be offered pursuant to this prospectus.

PLAN OF DISTRIBUTION

We may sell the offered securities through agents, through underwriters or dealers, directly to one or more purchasers, through a combination of any of these methods of sale or through any other methods described in any applicable prospectus supplement. The distribution of securities may be effected, from time to time, in one or more transactions, including block transactions and transactions on the New York Stock Exchange or any other organized market where the securities may be traded. The securities may be sold at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to the prevailing market prices or at negotiated prices. The consideration received in connection with such sales may be cash or another form negotiated by the parties. Agents, underwriters or dealers may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions or commissions to be received from us or from the purchasers of the securities. We will identify the specific plan of distribution, including any underwriters, dealers, agents or direct purchasers and their compensation in any applicable prospectus supplement.

Any applicable prospectus supplement will set forth whether or not an underwriter may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids.

In compliance with the guidelines of the Financial Industry Regulatory Authority (“FINRA”), the aggregate maximum discount, commission or agency fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed 8% of the proceeds from any offering pursuant to this prospectus and any applicable prospectus supplement.

It is possible that one or more underwriters may make a market in a class or series of securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for any of the securities.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution

The following statement sets forth our expenses in connection with the offering described in this Registration Statement (all of which will be borne by us). All amounts shown are estimated.

Item 15. Indemnification of Directors and Officers

Horace Mann is a Delaware corporation. Section 145 of the General Corporation Law of the State of Delaware empowers a Delaware corporation to indemnify any persons who are, or are threatened to be made, parties to any threatened, pending or completed legal action, suit or proceedings, whether civil, criminal, administrative or investigative (other than action by or in the right of such corporation), by reason of the fact that such person was an officer or director of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such officer or director acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests, and, for criminal proceedings, had no reasonable cause to believe his conduct was illegal. A Delaware corporation may indemnify officers and directors in an action by or in the right of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation in the performance of his duty. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses which such officer or director actually and reasonably incurred.

Article 9 of Horace Mann’s Certificate of Incorporation provides as follows:

Ninth. The Corporation shall indemnify each Director, Officer, employee or agent of the Corporation and each person who is or was serving at the request of the Corporation as a Director, Officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise in the manner and to the extent provided in the By-laws of the Corporation as the same may be amended from time to time.

Article 8 of Horace Mann’s by-laws provides as follows:

Section 8.1. General. The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative (other than an action by or in the right of the Corporation) by reason of the fact that such person is or was a Director, Officer, employee, or agent of the Corporation, or is or was serving at the request of the Corporation as a Director, Officer, employee, or agent of another corporation, partnership, joint

II-1

venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit, or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the conduct was unlawful. The termination of any action, suit, or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that the conduct was unlawful.

Section 8.2. Derivative Actions. The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that such person is or was a Director, Officer, employee, or agent of the Corporation, or is or was serving at the request of the Corporation as a Director, Officer, employee, or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Court of Chancery of the State of Delaware or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

Section 8.3. Indemnification in Certain Cases. To the extent that a Director, Officer, employee, or agent of the Corporation has been successful on the merits or otherwise in defense of any action, suit, or proceeding referred to in Sections 8.1. and 8.2. of this Article 8, or in defense of any claim, issue, or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith.

Section 8.4. Procedure. Any indemnification under Sections 8.1. and 8.2. of this Article 8 (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the Director, Officer, employee, or agent is proper in the circumstances because such person has met the applicable standard of conduct set forth in said Sections 8.1. and 8.2. Such determination shall be made (a) by the Board of Directors by a majority vote of a quorum consisting of Directors who were not parties to such action, suit, or proceeding, or (b) if such quorum is not obtainable, or, even if obtainable, a majority vote of a quorum of disinterested Directors so directs, by independent legal counsel in a written opinion, or (c) by the Stockholders.

Section 8.5. Advances for Expenses. Expenses incurred in defending a civil or criminal action, suit, or proceeding shall be paid by the Corporation in advance of the final disposition of such action, suit, or proceeding upon receipt of an undertaking by or on behalf of the Director, Officer, employee, or agent to repay such amount if it shall be ultimately determined that such person is not entitled to be indemnified by the Corporation as authorized in this Article 8.

Section 8.6. Rights Not Exclusive. The indemnification and advancement of expenses provided by this Article 8 shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any law, by-law, agreement, vote of Stockholders or disinterested Directors or otherwise, both as to action in the official capacity of such person and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a Director, Officer, employee, or agent and shall inure to the benefit of the heirs, executors, and administrators of such a person. Any repeal, modification, or amendment of this Article 8 shall not adversely affect any rights or obligations then existing between the Corporation and any then incumbent or former Director, Officer, employee,

II-2

or agent with respect to any facts then or theretofore existing or any action, suit, or proceeding theretofore or thereafter brought based in whole or in part upon such facts.

Section 8.7. Insurance. The Corporation shall have power to purchase and maintain insurance on behalf of any person who is or was a Director, Officer, employee, or agent of the Corporation, or is or was serving at the request of the Corporation as a Director, Officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of the status of such person as such, whether or not the Corporation would have the power to indemnify such person against such liability under the provisions of this Article 8.

Section 8.8. Definition of Corporation.
