PROSPECTUS

Heritage Insurance Holdings, Inc.

2,222,215 Shares of Common Stock

The selling stockholders named in this prospectus may offer and sell from time to time up to 2,222,215 shares of our common stock. The shares of our common stock that may be offered by the selling stockholders using this prospectus were issued to the selling stockholders in connection with our acquisition of NBIC Holdings, Inc., the parent company of Narragansett Bay Insurance Company, a leading specialty underwriter of personal residential insurance products and services in states along the Eastern seaboard, on November 30, 2017. We will not receive any of the proceeds from the sale of shares of common stock by the selling stockholders. We will bear all expenses of the offering of common stock, except that the selling stockholder will pay any applicable underwriting fees, discounts or commissions and certain transfer taxes.

Our registration of the shares of common stock covered by this prospectus does not mean that the selling stockholders will offer or sell any of the shares. The selling stockholders may sell the shares of common stock covered by this prospectus in a number of different ways and at varying prices. We provide more information about how the selling stockholders may sell the shares in the section entitled “Plan of Distribution” beginning on page 7.

Our common stock is listed on The New York Stock Exchange under the symbol “HRTG”. On January 31, 2018, the last reported sale price of our common stock on The New York Stock Exchange was $17.03 per share.

Investing in the common stock involves risks. See “Risk Factors” on page 3 of this prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

The date of this prospectus is February 1, 2018.

TABLE OF CONTENTS

i

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission (the “SEC”), using a “shelf” registration process. Under this shelf process, the selling stockholders identified in this prospectus may offer or sell shares of our common stock, as described in this prospectus, in one or more offerings from time to time.

We may also authorize one or more free writing prospectuses or prospectus supplements to be provided to you in connection with these offerings. Any related free writing prospectus or prospectus supplement may also add, update or change information contained in this prospectus or in any documents that we have incorporated by reference into this prospectus and, accordingly, to the extent inconsistent, information in this prospectus is superseded by the information in any accompanying prospectus supplement or any related free writing prospectus or pursuant to any document hereafter incorporated by reference.

You should only rely on the information contained or incorporated by reference in this prospectus and any applicable prospectus supplement or any related free writing prospectus that we may authorize to be provided to you. We and the selling stockholders have not authorized any other person to provide you with different information or make any representations other than those contained in this prospectus or in any applicable prospectus supplement or related free writing prospectus. If anyone provides you with different or inconsistent information, you should not rely on it. You should not assume that the information contained or incorporated by reference in this prospectus or any applicable prospectus supplement or any related free writing prospectus is accurate as of any date other than the date on the cover of the applicable document. Our business, financial condition, results of operations and prospects may have changed since that date.

We urge you to read carefully this prospectus, the documents incorporated herein by reference (as supplemented and amended) and the additional information described below under the headings “Where You Can Find More Information” and “Information Incorporated By Reference” before deciding whether to purchase any of the shares of our common stock being offered hereunder.

Unless otherwise indicated or the context otherwise requires, all references to “Heritage,” “Company,” “Registrant,” “we,” “our,” “ours” and “us” refer to Heritage Insurance Holdings, Inc. and its subsidiaries. When we refer to “you” in this section, we mean all prospective purchasers of the securities being offered by this prospectus and any accompanying prospectus supplement, whether they are or will be the holders or only indirect owners of those securities.

RISK FACTORS

Investing in the securities offered pursuant to this prospectus may involve a high degree of risk. You should carefully consider the risk factors described in this prospectus, in Part I, Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2016 and in our other reports filed from time to time with the SEC, which are incorporated by reference into this prospectus, as the same may be amended, supplemented or superseded from time to time by our filings under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Before making any investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus or in any applicable prospectus supplement. For more information, see the sections entitled “Where You Can Find More Information” and “Information Incorporated By Reference.” These risks could materially adversely affect our business, results of operations or financial condition and the value of our securities. You could lose all or part of your investment.

The terms of our Convertible Notes provide that we cannot satisfy our conversion obligations by delivering shares of common stock unless and until we obtain shareholder approval, and until we do, the accounting treatment for the Convertible Notes could have an adverse effect on our reported results of operations.

In connection with the NBIC Acquisition, we issued $125 million in aggregate principal amount of 5.875% Convertible Senior Notes due 2037 (the “Convertible Notes”). Unless and until we obtain the requisite shareholder approval, we must satisfy the conversion obligation of our outstanding Convertible Notes solely through the delivery of cash. Until we obtain shareholder approval, the conversion option that is part of the notes will be accounted for as a derivative liability pursuant to accounting standards relating to derivative instruments and hedging activities (notwithstanding other factors to be evaluated during each reporting period regarding the classification of derivative instruments). For each financial statement period after issuance of the notes, a hedge gain (or loss) will be reported in our income statement to the extent the valuation of the derivative liability changes from the previous period as a result of changes in the market price of our common stock or changes in other valuation inputs and assumptions. This could result in significant fluctuations in our consolidated statement of comprehensive income (loss) from period to period and have a material adverse impact on our earnings per share. In addition, this could adversely affect our effective tax rate, further reducing earnings per share. Once shareholder approval is obtained, the conversion option is classified in the equity section of the balance sheet and a quarterly valuation is not required, thereby limiting the volatility of an adverse impact to earnings.

Settlement of our conversion obligations in shares of common stock may dilute the ownership interest of our stockholders, or may otherwise depress the price of our common stock.

Following shareholder approval, if we elect to settle our conversion obligations in shares of common stock (other than paying cash in lieu of delivering any fractional share), the conversion of some or all Convertible Notes would dilute the ownership interests of existing stockholders. If the Convertible Notes become convertible under the terms of the indenture, and if holders subsequently elect to convert their notes, we could be required to deliver to them a significant number of shares of our common stock, should we elect to settle in shares of common stock in lieu of cash. Any sales in the public market of the common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of the Convertible Notes may encourage short selling by market participants because the conversion of such notes could be used to satisfy short positions, or anticipated conversion of such notes into shares of our common stock could depress the price of our common stock.

FORWARD-LOOKING STATEMENTS

Certain statements and information in this prospectus and the documents we incorporate by reference may constitute “forward-looking statements.” These statements may be identified by the use of forward-looking terminology such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “should,” or the negative thereof or other variations thereon or comparable terminology. All statements contained or incorporated in this prospectus which address operating performance, events or developments that we expect or anticipate may occur in the future, including statements about our expectations, beliefs, plans, objectives, assumptions or future events or performance, are forward-looking statements. Important factors, risks and uncertainties that may cause actual results to differ from those expressed in our forward-looking statements include, but are not limited to:

3

Given these risks and uncertainties, we caution you not to place undue reliance on these forward-looking statements. The forward-looking statements included in or incorporated by reference into this prospectus are made only as of the date on the cover of the applicable document. We do not undertake and specifically decline any obligation to update any of these statements or to publicly announce the results of any revisions to any of these statements to reflect future events or developments.

USE OF PROCEEDS

The proceeds from the sale of the common stock offered pursuant to this prospectus are solely for the account of the selling stockholders. Accordingly, we will not receive any proceeds from the sale of the common stock offered pursuant to this prospectus.

SELLING STOCKHOLDERS

The table below sets forth, as of the date of this prospectus, the names of the selling stockholders for whom we are registering the resale of shares of our common stock from time to time and the number of shares that the selling stockholders may offer pursuant to this prospectus. The shares offered by the selling stockholders were issued at the closing of the NBIC Acquisition pursuant to subscription agreements entered into with the selling stockholders in accordance with the Merger Agreement, which issuances were made pursuant to an exemption from the registration requirements of the Securities Act provided in Section 4(a)(2) of the Securities Act. We have filed with the SEC under the Securities Act the registration statement of which this prospectus forms a part pursuant to the registration rights agreement entered into with the selling stockholders, as described below.

In connection with the closing of the NBIC Acquisition and the issuance of shares of our common stock to the selling stockholders, we entered into a registration rights agreement with the selling stockholders. Subject to the terms and conditions of the registration rights agreement, we agreed to file a shelf registration statement on Form S-3 to cover the shares of common stock received by each selling stockholder in connection with the NBIC Acquisition, to use our commercially reasonable efforts to cause the registration statement to be declared effective promptly and to keep the registration statement effective until the shares offered under this prospectus (1) have been disposed of by the selling stockholders in accordance with the registration statement, (2) have been sold in accordance with Rule 144 under the Securities Act or (3) cease to be outstanding.

The table below sets forth certain information known to us, based on written representations from the selling stockholders, with respect to the beneficial ownership of our shares of common stock held by the selling stockholders as of January 30, 2018, except as described in the notes to such table. Because the selling stockholders may sell, transfer or otherwise dispose of all, some or none of the shares of our common stock covered by this prospectus, we cannot determine the number of such shares that will be sold, transferred or otherwise disposed of by the selling stockholders, or the amount or percentage of shares of our common stock that will be held by the selling stockholders upon termination of any particular offering. See “Plan of Distribution.” Unless otherwise indicated, the address of each beneficial owner listed in the table below is: c/o Narragansett Bay Insurance Company, 25 Maple St, Pawtucket, RI 02860. Information about the selling stockholders may change over time. Any changed information will be set forth in supplements to this prospectus, if required. For purposes of the table below, we assume that the selling stockholders will sell all of their shares of common stock covered by this prospectus.

The percentages of shares owned set forth below are based on 26,560,004 shares of our common stock outstanding as of January 30, 2018.

PLAN OF DISTRIBUTION

The selling stockholders and any of their pledgees, donees, transferees, assignees or other successors-in-interest may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices. The selling stockholders may use one or more of the following methods when disposing of the shares or interests therein:

The selling stockholders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by the selling stockholders may arrange for other broker-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The selling stockholders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved. The selling stockholders may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of the shares if liabilities are imposed on that person under the Securities Act.

The selling stockholders may from time to time pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell shares of common stock from time to time under this prospectus, or under a supplement or amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.

Upon being notified in writing by the selling stockholders that any material arrangement has been entered into with a broker-dealer for the sale of common stock through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, we will file a supplement to this prospectus, if required, pursuant to Rule 424(b) under the Securities Act, disclosing (i) the name of the participating broker-dealer(s), (ii) the number of shares involved, (iii) the price at which such shares of common stock were sold, (iv) the commissions paid or discounts or concessions allowed to such broker-dealer(s), where applicable, and (v) other facts material to the transaction that are required to be disclosed. In addition, upon being notified in writing by the selling stockholders that a donee or pledge intends to sell more than 500 shares of common stock, we will file a supplement to this prospectus if then required in accordance with applicable securities law.

7

The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

In connection with the sale of the shares of common stock or interests in shares of common stock, the selling stockholders may enter into hedging transactions after the effective date of the registration statement of which this prospectus is a part with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of common stock short after the effective date of the registration statement of which this prospectus is a part and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions after the effective date of the registration statement of which this prospectus is a part with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The selling stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

We have advised the selling stockholders that they are required to comply with Regulation M promulgated under the Exchange Act during such time as they may be engaged in a distribution of the shares. The foregoing may affect the marketability of the common stock.

We have agreed to indemnify the selling stockholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus.

The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions, if any. The selling stockholders reserve the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

The following table sets forth the various costs and expenses payable by us in connection with the distribution of the securities registered hereby. All amounts are estimates, except for the SEC registration fee.

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 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

II-1

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.

Underwriting Agreement

The form of underwriting agreement to be filed by amendment to this registration statement or incorporated by reference from documents filed or to be filed with the SEC may provide for indemnification of directors and certain officers of the registrant by the underwriters against certain liabilities.

II-2

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) 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.
