We and any underwriter or agent that we may from time to time retain may also provide other information relating to an offering, which we refer to as “other offering material.” The prospectus supplement as well as the other offering material may also add, update or change information contained in this prospectus or in the documents we have incorporated by reference into this prospectus. You should read this prospectus, any prospectus supplement, and any other offering material (including any free writing prospectus) prepared by or on behalf of us for a specific offering of securities, together with additional information described in the section entitled “Where You Can Find More Information”. Throughout this prospectus, where we indicate that information may be supplemented in an applicable prospectus supplement or supplements, that information may also be supplemented in other offering material. If there is any inconsistency between this prospectus and the information contained in a prospectus supplement, you should rely on the information in the prospectus supplement.

USE OF PROCEEDS

Unless otherwise specified in the applicable prospectus supplement, the net proceeds we receive from the sale of the securities offered by this prospectus and the applicable prospectus supplement will be used for working capital and other general corporate purposes. We will have significant discretion in the use of any net proceeds.

General corporate purposes may include, but are not limited to:

The net proceeds from the sale of securities may be invested temporarily or applied to repay short-term debt until they are used for their stated purpose. When particular securities are offered, we will describe in the applicable prospectus supplement our intended use for the net proceeds received from the sale of such securities.

6

DESCRIPTION OF CAPITAL STOCK

The following descriptions of our capital stock and of certain provisions of Delaware law are subject to and qualified in their entirety by reference to our Certificate of Incorporation (the “Certificate”) and our By-laws (the “By-laws”). Copies of the Certificate and the By-laws have been filed with the SEC and are filed as exhibits to the registration statement of which this prospectus forms a part.

General

As of the date hereof, our authorized capital stock consists of 50,000,000 shares of common stock, $0.0001 par value, and 5,000,000 shares of preferred stock, $0.0001 par value. As of March 1, 2021, there were 27,965,190 shares of common stock issued and outstanding and no shares of preferred stock issued and outstanding. All of our outstanding shares of common stock are fully paid and non-assessable.

Common Stock

Voting. Holders of common stock are entitled to one vote for each share held on all matters subject to a vote of stockholders, subject to the rights of holders of any outstanding preferred stock. Accordingly, holders of a majority of the shares of common stock entitled to vote in any election of directors may elect all of the directors standing for election, subject to the rights of holders of any outstanding preferred stock.

Dividends. Holders of common stock will be entitled to receive ratably any dividends that the board of directors may declare out of funds legally available therefor, subject to any preferential dividend rights of outstanding preferred stock.

Liquidation, Dissolution or Winding Up. Upon our liquidation, dissolution or winding up, the holders of common stock will be entitled to receive ratably our net assets available after the payment of all debts and other liabilities and subject to the prior rights of holders of any outstanding preferred stock. Holders of common stock have no preemptive, subscription, redemption or conversion rights. There are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of our capital stock are fully paid and nonassessable.

Preferred Stock

We are authorized to issue 5,000,000 shares of preferred stock, which may be issued from time to time in one or more series upon authorization by the board of directors. Our board of directors, without further approval of the stockholders, is authorized to fix the number of shares constituting any series, as well as the dividend rights and terms, conversion rights and terms, voting rights and terms, redemption rights and terms, liquidation preferences and any other rights, preferences, privileges and restrictions applicable to each series of preferred stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could also adversely affect the voting power and dividend and liquidation rights of the holders of common stock. The issuance of preferred stock could also, under certain circumstances, have the effect of making it more difficult for a third-party to acquire, or discouraging a third-party from acquiring, a majority of our outstanding voting stock or otherwise adversely affect the market price of our common stock. It is not possible to state the actual effect of the issuance of any shares of preferred stock on the rights of holders of common stock until the board of directors determines the specific rights of that series of preferred stock.

The particular terms of any series of preferred stock that we offer under this prospectus will be described in the applicable prospectus supplement relating to that series of preferred stock. Those terms may include:

7

You should refer to the certificate of designations establishing a particular series of preferred stock which will be filed with the Secretary of State of the State of Delaware and the SEC in connection with any offering of preferred stock.

Each prospectus supplement relating to a series of preferred stock may describe certain U.S. federal income tax considerations applicable to the purchase, holding and disposition of such series of preferred stock.

Elimination of Liability in Certain Circumstances

Our Certificate eliminates the liability of our directors to us or our stockholders for monetary damages resulting from breaches of their fiduciary duties as directors. Directors will remain liable for breaches of their duty of loyalty to us or our stockholders, as well as for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, and transactions from which a director derives improper personal benefit. Our Certificate will not absolve directors of liability for payment of dividends or stock purchases or redemptions by us in violation of Section 174 (or any successor provision of the Delaware General Corporation Law).

The effect of this provision is to eliminate the personal liability of directors for monetary damages for actions involving a breach of their fiduciary duty of care, including any such actions involving gross negligence. We do not believe that this provision eliminates the liability of our directors to us or our stockholders for monetary damages under the federal securities laws. The Certificate and By-laws provide indemnification for the benefit of our directors and officers to the fullest extent permitted by the Delaware General Corporation Law as it may be amended from time to time, including most circumstances under which indemnification otherwise would be discretionary.

Number of Directors; Removal; Vacancies

Our By-laws provide that we have five directors, provided that this number may be changed by the board of directors. Vacancies on the board of directors may be filled only by the affirmative vote of a majority of the remaining directors then in office. Our By-laws provide that, subject to the rights of holders of any future series of preferred stock, directors may be removed, with or without cause, at meetings of stockholders by the affirmative vote of the holders of a majority of the outstanding shares entitled to vote generally in the election of directors.

Special Meetings of Stockholders; Limitations on Stockholder Action by Written Consent

Our Certificate provides that special meetings of our stockholders may be called only by our chairman of the board, our chief executive officer, our board of directors or holders of not less than a majority of our issued and outstanding voting stock. Any action required or permitted to be taken by our stockholders must be effected at an annual or special meeting of stockholders and may not be effected by written consent unless the action to be effected and the taking of such action by written consent have been approved in advance by our board of directors.

8

Amendments; Vote Requirements

Certain provisions of our Certificate and By-laws provide that the affirmative vote of a majority of the shares entitled to vote on any matter is required for stockholders to amend our Certificate or By-laws, including those provisions relating to action by written consent and the ability of stockholders to call special meetings.

Authorized but Unissued Shares

The authorized but unissued shares of common stock will be available for future issuance without stockholder approval. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued shares of common stock could render it more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Advance Notice Requirements for Stockholder Proposals and Nomination of Directors

Our By-laws provide that stockholders seeking to bring business before an annual meeting of stockholders, or to nominate candidates for election as directors at an annual meeting of stockholders, must provide timely notice in writing. To be timely, a stockholder’s notice must be delivered to or mailed and received at our principal executive offices not less than 90 days nor more than 120 days prior to the anniversary date of the immediately preceding annual meeting of stockholders. However, in the event that the annual meeting is called for a date that is more than 30 days before or more than 60 days after such anniversary date, such notice will be timely only if received not earlier than the close of business on the 120th day prior to the date of such annual meeting and not later than the close of business on the later of the 90th day prior to the date of such annual meeting or, if the first public announcement of the date of such annual meeting is less than 100 days prior to the date of such annual meeting, the 10th day following the day on which public announcement of the date of such meeting is first made by the Company. Our By-laws also specify requirements as to the form and content of a stockholder’s notice.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A.

Listing

Our common stock is listed on the New York Stock Exchange under the symbol “HRTG.”

DESCRIPTION OF DEBT SECURITIES

The following description, together with the additional information we may include in any applicable prospectus supplements and in any related free writing prospectuses, summarizes the material terms and provisions of the debt securities that we may offer under this prospectus. While the terms summarized below will apply generally to any debt securities that we may offer, we will describe the particular terms of any debt securities in more detail in the applicable prospectus supplement. The terms of any debt securities offered under a prospectus supplement may differ from the terms described below.

We may issue debt securities from time to time in one or more distinct series. The debt securities may be senior debt securities or subordinated debt securities. Senior debt securities may be issued under a senior indenture and subordinated debt securities may be issued under a subordinated indenture. If we issue debt securities pursuant to an indenture, in the applicable prospectus supplement we will specify the trustee under such indenture. We will include in a supplement to this prospectus the specific terms of debt securities being offered, including the terms, if any, on which debt securities may be convertible into or exchangeable for common stock, preferred stock or other debt securities. The statements and descriptions in this prospectus or in any prospectus supplement regarding provisions of debt securities and any indentures are summaries of these provisions and are subject to, and are qualified in their entirety by reference to, all of the provisions of the debt securities and the indentures (including any amendments or supplements we may enter into from time to time which are permitted under the debt securities or any indenture).

Unless otherwise specified in a prospectus supplement, the debt securities will be direct unsecured obligations of Heritage. Any debt securities designated as senior will rank equally with any of our other senior and unsubordinated debt. Any debt securities designated as subordinated will be subordinate and junior in right of payment to any senior indebtedness. There may be subordinated debt securities that are senior or junior to other series of subordinated debt securities.

The applicable prospectus supplement will set forth the terms of the debt securities or any series thereof, including, if applicable:

10

11

In addition, any debt securities offered hereby may be convertible into or exchangeable for common stock, preferred stock or other debt securities. The applicable prospectus supplement will set forth the terms and conditions of such conversion or exchange, including, if applicable:

This prospectus is part of a registration statement that provides that we may issue debt securities from time to time in one or more series under one or more indentures, in each case with the same or various maturities, at par or at a discount. Unless indicated in a prospectus supplement, we 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.

We intend to disclose any restrictive covenants for any issuance or series of debt securities in the applicable prospectus supplement.

12

DESCRIPTION OF WARRANTS

We expect the following provisions will generally apply to warrants we may offer, unless we specify otherwise in the applicable prospectus supplement.

We may issue warrants for the purchase of common stock, preferred stock or debt securities (collectively “warrants”). Warrants may be issued independently or together with common stock, preferred stock or debt securities and may be attached to or separate from any offered securities. Each series of warrants will be issued under a separate warrant agreement (a “warrant agreement”) to be entered into between us and a bank or trust company, as warrant agent (the “warrant agent”). The warrant agent will act solely as our agent in connection with the warrants and will not have any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. The statements and descriptions in this prospectus or in any prospectus supplement regarding provisions of the warrants are subject to, and are qualified in their entirety by reference to, the provisions of the warrant agreement.

General

If we offer warrants to purchase common stock, preferred stock or debt securities, the related prospectus supplement will describe the terms of the warrants, including, if applicable:

The shares of common or preferred stock issuable upon exercise of the warrants will, when issued in accordance with the warrant agreement, be fully paid and non-assessable.

No Rights

Holders of warrants will not be entitled, by virtue of being such holders, to any rights of holders of the underlying securities. For example, holders of warrants will have no rights to:

13

Exchange of Warrant Certificate

Warrant certificates may be exchanged for new warrant certificates of different denominations and may (if in registered form) be presented for registration of transfer at the corporate trust office of the warrant agent, which will be listed in the related prospectus supplement, or at such other office as may be set forth therein.

Exercise of Warrants

Warrants may be exercised by surrendering the warrant certificate at the corporate trust office of the warrant agent, with the form of election to purchase on the reverse side of the warrant certificate properly completed and executed, and by payment in full of the exercise price, as set forth in the prospectus supplement. Upon the exercise of warrants, the warrant agent will, as soon as practicable, deliver the securities in authorized denominations in accordance with the instructions of the exercising warrant holder and at the sole cost and risk of such holder. If less than all of the warrants evidenced by the warrant certificate are exercised, a new warrant certificate will be issued for the remaining amount of warrants.

14

DESCRIPTION OF SUBSCRIPTION RIGHTS

We may issue subscription rights to purchase debt securities, preferred stock, common stock or other securities. These subscription rights may be issued independently or together with any other security offered hereby and may or may not be transferable by the stockholder receiving the subscription rights in such offering. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any securities remaining unsubscribed after such offering.

The applicable prospectus supplement will describe the specific terms of any offering of subscription rights for which this prospectus is being delivered. A holder or prospective holder of subscription rights should refer to the applicable prospectus supplement for more specific information.

15

DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

We may issue stock purchase contracts, representing contracts obligating holders to purchase from us, and requiring us to sell to the holders, a specified number of shares of common stock at a future date or dates.

The price per share of common stock may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts. The stock purchase contracts may be issued separately or as a part of units, or stock purchase units, consisting of a stock purchase contract and either (x) senior debt securities, senior subordinated debt securities, subordinated debt securities or junior subordinated debt securities, or (y) debt obligations of third parties, including U.S. Treasury securities, in each case, securing the holder’s obligations to purchase our common stock under the stock purchase contracts. The stock purchase contracts may require us to make periodic payments to the holders of the stock purchase contracts or vice versa, and such payments may be unsecured or prefunded on some basis. The stock purchase contracts may require holders to secure their obligations thereunder in a specified manner and in certain circumstances we may deliver newly issued prepaid stock purchase contracts, or prepaid securities, upon release to a holder of any collateral securing such holder’s obligations under the original stock purchase contract. The applicable prospectus supplement will describe the terms of any stock purchase contracts or stock purchase units and, if applicable, prepaid securities.

16

PLAN OF DISTRIBUTION

We may sell common stock, preferred stock, debt securities, warrants, subscription rights, stock purchase contracts, and/or stock purchase units in one or more of the following ways from time to time:

The prospectus supplements relating to an offering of securities will set forth the terms of such offering, including:

Any public offering prices, discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

We may distribute the securities from time to time in one or more of the following ways:

Unless otherwise indicated in the applicable prospectus supplement, if we use underwriters for a sale of securities, the underwriters will acquire the securities for their own account. The underwriters may resell the securities in one or more transactions, including negotiated transactions, at a fixed public offering price, or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. The offered securities may be offered either to the public through underwriting syndicates represented by one or more managing underwriters or by one or more underwriters without a syndicate. Unless otherwise indicated in a prospectus supplement, the underwriters will be obligated to purchase all the securities of the series offered if they purchase any of the securities of that series. We may change from time to time any initial public offering price and any discounts or concessions the underwriters allow or reallow or pay to dealers. We may use underwriters with whom we have a material relationship. We will describe in the prospectus supplement naming the underwriter the nature of any

17

such relationship. We may designate agents who agree to use their reasonable efforts to solicit purchasers for the period of their appointment or to sell securities on a continuing basis. We may also sell securities directly to one or more purchasers without using underwriters or agents.

Underwriters, dealers, or agents may receive compensation in the form of discounts, concessions, or commissions from us or from purchasers of the securities as their agents in connection with the sale of the securities. These underwriters, dealers, or agents may be considered to be underwriters under the Securities Act. As a result, discounts, commissions, or profits on resale received by underwriters, dealers, or agents may be treated as underwriting discounts and commissions. Each prospectus supplement will identify any underwriter, dealer, or agent and describe any compensation received by them from us. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

In connection with underwritten offerings of the offered securities and in accordance with applicable law and industry practice, underwriters may over-allot or effect transactions that stabilize, maintain or otherwise affect the market price of the offered securities at levels above those that might otherwise prevail in the open market, including by entering stabilizing bids, effecting syndicate covering transactions or imposing penalty bids, each of which is described below:

These stabilizing transactions, over-allotments, syndicate covering transactions, and penalty bids may have the effect of raising or maintaining the market price of our common stock or preventing or slowing a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the New York Stock Exchange or otherwise and, if commenced, may be discontinued at any time.

Underwriters, dealers, and agents may be entitled under agreements entered into with us to indemnification against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments they may be required to make in respect of these liabilities thereof. Underwriters, dealers, and agents and their affiliates may be customers of, may engage in transactions with, or perform services for us in the ordinary course of business for which they receive compensation.

Unless otherwise specified in the applicable prospectus supplement, each class or series of securities will be a new issue with no established trading market, other than our common stock, which is listed on the New York Stock Exchange. We may elect to list any other class or series of securities on any exchange, but we are not obligated to do so. 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.

Under the securities laws of some states, the securities offered by this prospectus may be sold in those states only through registered or licensed brokers or dealers.

Any person participating in the distribution of common stock registered under the registration statement that includes this prospectus will be subject to applicable provisions of the Exchange Act, and applicable SEC rules and regulations, including, among others, Regulation M, which may limit the timing of purchases and sales of

18

any of our common stock by any such person. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of our common stock to engage in market-making activities with respect to our common stock. These restrictions may affect the marketability of our common stock and the ability of any person or entity to engage in market-making activities with respect to our common stock.

Other than our common stock, which is listed on the New York Stock Exchange, each of the securities issued hereunder will be a new issue of securities, will have no prior trading market, and may or may not be listed on a national securities exchange. Any common stock sold pursuant to a prospectus supplement will be listed on the New York Stock Exchange, subject to official notice of issuance. Any underwriters to whom we sell securities for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot assure you that there will be a market for the offered securities.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

Estimated expenses of the offering, other than those relating to the SEC registration fee, are not presently known. The table below sets forth the general categories of expenses (other than underwriting discounts and commissions) that we anticipate we will incur in connection with the offering of securities under this Registration Statement. An estimate of the aggregate expenses in connection with the issuance and distribution of the securities being offered will be included in the applicable prospectus supplement.

Item 15. Indemnification of Directors and Officers.

Delaware General Corporation Law

We are incorporated under the laws of the State of Delaware. Our Certificate and By-laws provide for the indemnification of our directors, officers, employees and agents to the fullest extent permitted under the Delaware General Corporation Law. Section 145 of the Delaware General Corporation Law provides that a corporation shall have the power to 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 the 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), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the 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 person’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement or 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 the 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 person’s conduct was unlawful.

In addition, we have the power to indemnify any person who was or is a party or is threatened to be made a party to, or otherwise involved (including involvement as a witness) in, 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 the 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 the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the 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 a Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of

II-1

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 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director:

Our Certificate includes such a provision. As a result of this provision, Heritage and its stockholders may be unable to obtain monetary damages from a director for certain breaches of his or her fiduciary duty to Heritage. This provision does not, however, eliminate a director’s fiduciary responsibilities and, in appropriate circumstances, equitable remedies such as injunctive or other forms of non-monetary relief will remain available under Delaware law. The provision also does not affect a director’s responsibilities under any other laws, such as the federal securities laws.

Indemnification Agreements

We have entered into indemnification agreements with each of our directors and executive officers that may be broader than the specific indemnification provisions contained in the Delaware General Corporation Law, as amended from time to time. These indemnification agreements may require us, among other things, to indemnify our directors and executive officers against liabilities that may arise by reason of their status or service. These indemnification agreements may also require us to advance all expenses incurred by the directors or executive officers in investigating or defending any such action, suit or proceeding. However, an individual will not receive indemnification for judgments, settlements or expenses if he or she is found liable to Heritage (except to the extent the court determines he or she is fairly and reasonably entitled to indemnity for expenses that the court shall deem proper).

Directors’ and Officers’ Liability Insurance

We maintain directors’ and officers’ liability insurance policies, which insure against liabilities that our directors or officers may incur in such capacities. These insurance policies, together with the indemnification agreements, may be sufficiently broad to permit indemnification of our directors and officers for liabilities, including reimbursement of expenses incurred, arising under the Securities Act or otherwise.

Item 16. Exhibits.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

provided, however, that paragraphs (i), (ii) and (iii) of this section (1) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

II-4

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person of the registrant in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
