The Merger and the Merger Agreement (pages      and     )

On August 23, 2017, Home and St. Martin entered into an Agreement and Plan of Merger, or the merger agreement, under which St. Martin will merge with and into Home, with Home surviving the merger. Upon completion of the merger, the separate existence of St. Martin will terminate and St. Martin common stock will no longer be outstanding. Also under the merger agreement, immediately following with the merger, St. Martin Bank will be merged with and into Home Bank, with Home Bank as the surviving entity in the bank merger. Completion of the merger is subject to a variety of conditions, including approval of the merger agreement by shareholders of each of Home and St. Martin. We currently expect to complete these mergers during the fourth quarter of 2017 or the first quarter of 2018. The merger agreement is attached to this joint proxy statement/prospectus as Annex A and is incorporated by reference herein.

In the Merger, St. Martin Shareholders Will Receive Shares of Home Common Stock (page     )

The merger agreement provides for the merger of St. Martin with and into Home. If the merger is completed, St. Martin shareholders will receive 9.2839 shares of Home common stock for each share of St. Martin common stock they hold immediately prior to the merger. Home will not issue any fractional shares of Home common stock in the merger. St. Martin shareholders who would otherwise be entitled to a fraction of a share of Home common stock upon the completion of the merger will instead receive, for the fraction of a share, an amount

in cash (rounded to the nearest cent) based on the average Home share closing price during the ten consecutive trading day period specified in the merger agreement. The merger agreement also provides that St. Martin will pay a special cash distribution of $94.00 per share to shareholders of St. Martin immediately prior to the effectiveness of the merger.

Home common stock is listed on the NASDAQ Global Select Market under the symbol “HBCP”. St. Martin common stock is not listed on any national securities exchange or quoted on any interdealer quotation system. The following table shows the closing sale prices of Home common stock on August 22, 2017, the last full trading day before the public announcement of the merger agreement, and on             , 2017, the last practicable trading day before the date of this joint proxy statement/prospectus. This table also shows the implied value of the stock merger consideration payable for each share of St. Martin common stock, which was calculated by multiplying the closing price of Home common stock on those dates by the exchange ratio of 9.2839. Finally, the table shows the aggregate of the implied value of the stock merger consideration plus the value of the special cash distribution to be paid by St. Martin with respect to each share of St. Martin common stock.

The merger agreement governs the merger. The merger agreement is included in this joint proxy statement/prospectus as Annex A. All descriptions in this summary and elsewhere in this joint proxy statement/prospectus of the terms and conditions of the merger are qualified by reference to the merger agreement. Please read the merger agreement carefully for a more complete understanding of the merger.

The values in the table above are illustrative only. The value of the stock merger consideration that a St. Martin shareholder actually receives will be based on the actual closing price on the NASDAQ Global Select Market of Home common stock upon completion of the merger, which is likely to be different than the amounts set forth above.

The Merger Is Intended to Be Tax-Free to St. Martin Shareholders as to the Shares of Home Common Stock They Receive (page    )

The merger is intended to be treated as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, which we refer to as the Internal Revenue Code. One of the conditions to the respective obligations of Home and St. Martin to complete the merger is that each of Home and St. Martin receives an opinion from its respective legal counsel to that effect.

It is expected that St. Martin shareholders will not recognize gain or loss for U.S. federal income tax purposes upon the exchange of their shares of St. Martin common stock for shares of Home common stock pursuant to the merger, except with respect to any cash received by a St. Martin shareholder in lieu of fractional shares of Home common stock.

This tax treatment may not apply to all St. Martin shareholders. Determining the actual tax consequences of the merger to St. Martin shareholders can be complicated. St. Martin shareholders should consult their own tax advisor for a full understanding of the merger’s tax consequences that are particular to them.

The Merger Will Be Accounted for as a “Business Combination” (page     )

The merger will be treated as a “business combination” using the acquisition method of accounting with Home treated as the acquirer under United States generally accepted accounting principles (which we refer to as “GAAP”).

Special Meeting of Home Shareholders (page     )

Home plans to hold the Home special meeting on             , 2017, at     :00 a.m., local time, at                     ,                 , Lafayette, Louisiana. At the Home special meeting, Home shareholders will be asked to approve the merger agreement, to approve the issuance of shares of Home common stock in the merger, and to approve a proposal to allow the Home special meeting to be adjourned, if necessary or appropriate, to permit the solicitation of additional proxies in favor of approval of the merger agreement or the issuance of shares of Home common stock in the merger.

Home shareholders may vote at the Home special meeting if they owned Home common stock at the close of business on             , 2017, which is the record date for the Home special meeting. As of that date, there were approximately                      shares of Home common stock outstanding and entitled to vote. Home shareholders are entitled to cast one vote for each share of Home common stock owned on the record date.

As of the record date for the Home special meeting, Home’s directors and executive officers and their affiliates held                     shares of Home common stock, excluding shares that may be acquired upon the exercise of outstanding stock options.

As of the record date for the Home special meeting, St. Martin, its subsidiaries, and its directors and officers and their affiliates owned                      shares of Home common stock (excluding shares held as fiduciary, custodian or agent).

Home’s Board of Directors Recommends That Home Shareholders Vote “FOR” Approval of the Merger Agreement and “FOR” the Other Proposals to be Considered at the Home Special Meeting (page     )

Home’s board of directors has approved the merger agreement and the transactions contemplated thereby, including the merger, and unanimously recommends that Home shareholders vote “FOR” approval of the merger agreement, “FOR” approval of the stock issuance proposal, and “FOR” the proposal to allow the Home special meeting to be adjourned, if necessary or appropriate, to permit the solicitation of additional proxies in favor of the approval of the merger agreement or the stock issuance proposal.

Opinion of Home’s Financial Advisor (page     )

BSP Securities, LLC (which we refer to as “BSP”), Home’s financial advisor, delivered its opinion, dated August 22, 2017, to Home’s board of directors to the effect that, as of the date of the opinion and subject to factors, qualifications, limitations and assumptions set forth in the opinion, the stock merger consideration together with the special cash distribution to be paid by St. Martin to its shareholders immediately prior to the proposed merger and the consideration to be paid to holders of outstanding options to acquire shares of St. Martin common stock was fair, from a financial point of view, to Home.

The full text of the written opinion of BSP, which sets forth the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by BSP in connection with its opinion, is attached as Annex B to this joint proxy statement/prospectus. BSP’s opinion was for the information of, and directed to, Home’s board of directors (in its capacity as such) in connection with its consideration of the financial terms of the merger. BSP’s opinion is not a recommendation as to how any holder of Home’s common stock should vote with respect to the proposal to approve the merger agreement or any other matter. It does not address the underlying business decision of Home to engage in the merger, the relative merits of the merger as compared to any other alternative business strategies that might exist for Home or the effect of any other transaction in which Home might engage. The BSP opinion does not reflect any developments that may have occurred or may occur after the date of its opinion and prior to the completion of the merger. BSP will receive a fee for its services, including rendering the fairness opinion, in connection with the merger.

Special Meeting of St. Martin Shareholders (page     )

St. Martin plans to hold the St. Martin special meeting on             , 2017, at     :00 a.m., local time, at _                        ,                     ,                    , Louisiana. At the St. Martin special meeting, St. Martin shareholders will be asked to approve the merger agreement, to approve the termination of the St. Martin Shareholders’ Agreement effective as of the closing date of the merger, and to approve a proposal to allow the St. Martin special meeting to be adjourned, if necessary or appropriate, to permit the solicitation of additional proxies in favor of approval the merger agreement or of the Shareholders’ Agreement proposal.

St. Martin shareholders may vote at the St. Martin special meeting if they owned St. Martin common stock at the close of business on             , 2017, which is the record date for the St. Martin special meeting. As of that date, there were 207,552 shares of St. Martin common stock outstanding and entitled to vote. St. Martin shareholders are entitled to cast one vote for each share of St. Martin common stock owned on the record date.

As of the record date for the St. Martin special meeting, St. Martin directors and executive officers and their affiliates held                     shares of St. Martin common stock, excluding shares that may be acquired upon the exercise of outstanding stock options.

As of the record date for the St. Martin special meeting, Home, its subsidiaries, and its directors and executive officers and their affiliates owned                      shares of St. Martin common stock (excluding shares held as fiduciary, custodian or agent).

St. Martin’s Board of Directors Recommends That St. Martin Shareholders Vote “FOR” Approval of the Merger Agreement and “FOR” the Other Proposals to be Considered at the St. Martin Special Meeting (page     )

St. Martin’s board of directors has approved the merger agreement and the transactions contemplated thereby, including the merger, and unanimously recommends that St. Martin shareholders vote “FOR” approval of the merger agreement, “FOR” approval of the termination of the St. Martin Shareholders’ Agreement effective as of the closing date of the merger, and “FOR” the proposal to allow the St. Martin special meeting to be adjourned, if necessary or appropriate, to permit the solicitation of additional proxies in favor of the approval of the merger agreement or the Shareholders’ Agreement proposal.

Opinion of St. Martin’s Financial Advisor (page     )

At the August 23, 2017 meeting of the St. Martin board of directors, representatives of Raymond James & Associates, Inc. (which we refer to as “Raymond James”) rendered Raymond James’s written opinion to the St. Martin board, dated August 23, 2017, that, as of such date, the stock merger consideration, when considered together with the special cash distribution to be paid by St. Martin to its shareholders immediately prior to the merger pursuant to the merger agreement, was fair, from a financial point of view, to such holders, based upon and subject to the qualifications, assumptions and other matters considered in connection with the preparation of its opinion.

The full text of the written opinion of Raymond James, which sets forth, among other things, the various qualifications, assumptions and limitations on the scope of the review undertaken, is attached as Annex C to this joint proxy statement/prospectus and shareholders of St. Martin are encouraged to read it carefully in its entirety. Raymond James provided its opinion for the information and assistance of the St. Martin board of directors (solely in each director’s capacity as such) in connection with, and for purposes of, its consideration of the merger and its opinion only addresses whether the merger consideration, when considered together with the special cash distribution to be paid by St. Martin to its shareholders immediately prior to the merger, as of the date of the opinion, was fair, from a financial point of view, to the shareholders of St. Martin. The opinion of Raymond James did not address any other term or aspect of the merger agreement or the merger contemplated thereby. The Raymond James opinion does not constitute a recommendation to the board or any holder of St. Martin common stock as to how the St. Martin board of directors, such shareholder or any other person should vote or otherwise act with respect to the merger or any other matter.

St. Martin’s Directors and Executive Officers Have Interests in the Merger that Differ From Your Interests (page     )

In considering the information contained in this joint proxy statement/prospectus, St. Martin shareholders should be aware that St. Martin’s directors and executive officers have interests in the merger and have arrangements that are different from, or in addition to, those of St. Martin’s shareholders. These interests include, among others, the acceleration and lump sum payment of benefits under existing supplemental retirement plan (“SERP”) agreements with certain executive officers of St. Martin, the treatment of outstanding St. Martin’s option awards pursuant to the merger agreement, the entry into new employment agreements with Home, effective as of the effective time of the merger, by certain executive officers of St. Martin, and rights to ongoing indemnification and insurance coverage by the surviving corporation for acts or omissions occurring prior to the merger. These interests also include Home’s agreement to appoint, on or prior to the effective time of the merger, two current directors of St. Martin to the board of directors of Home and Home Bank. The St. Martin board of directors was aware of and considered those interests, among other matters, in reaching its decisions to approve the merger agreement and the transactions contemplated thereby and to recommend the approval of the merger agreement to St. Martin shareholders. See the section entitled “The Merger—Interests of St. Martin’s Directors and Executive Officers in the Merger” beginning on page      of this joint proxy statement/prospectus for a more detailed description of these interests.

Ownership of Home Common Stock Following the Merger (page     )

It is currently expected that former shareholders of St. Martin as a group will receive approximately 1,927,000 shares of Home common stock in the merger, which will constitute approximately 21% of the shares of Home common stock to be outstanding immediately after completion of the merger. As a result, current shareholders of Home as a group will own approximately 79% of the outstanding shares of Home common stock immediately after the completion of the merger.

St. Martin Shareholders Have Appraisal Rights in the Merger (page     )

Under Louisiana law, record holders of St. Martin shares have the right to demand in writing to receive a payment in cash for the “fair value” of their shares of St. Martin common stock as determined by an appraisal process. To exercise those appraisal rights, St. Martin shareholders must follow exactly the procedures specified under Louisiana law. These procedures are summarized in this joint proxy statement/prospectus. In addition, the text of the applicable provisions of Louisiana law is included as Annex D to this document. Failure to strictly comply with these provisions may result in the loss of appraisal’ rights. The value determined in the appraisal process may be more or less than the value a St. Martin shareholder would receive in the merger under the terms of the merger agreement.

St. Martin Has Agreed When and How It Can Consider Third-Party Acquisition Proposals (page     )

Home and St. Martin have agreed that St. Martin will not initiate, solicit, induce or encourage proposals from third parties regarding certain acquisitions of St. Martin, its shares, or its businesses, take any action or facilitate the making of an acquisition proposal, or engage in related discussions, negotiations or enter into any related agreements. However, St. Martin may (1) provide information in response to a request from a person who makes an unsolicited acquisition proposal, subject to such person entering into a confidentiality agreement that is no less favorable to St. Martin than its confidentiality agreement with Home, and (2) engage or participate in discussions or negotiations with a person who makes such an unsolicited acquisition proposal, if, but only if, (A) St. Martin has received a bona fide unsolicited written acquisition proposal that did not result from a breach of the merger agreement, (B) prior to taking any such action, St. Martin’s board of directors determines, in good faith, after consultation with its outside legal and financial advisors, that the acquisition proposal constitutes or is reasonably likely to lead to a superior proposal compared to the transactions contemplated by the merger agreement, (C) prior to furnishing or affording access to any information or data with respect to St. Martin or any of its subsidiaries or otherwise relating to the unsolicited acquisition proposal, St. Martin receives a confidentiality agreement with terms no less favorable to St. Martin than those contained in the confidentiality agreement between Home and St. Martin, and (D) the board of directors of St. Martin determines in good faith, after consultation with and having considered the advice of its outside legal counsel, that the failure to take any such actions would be reasonably likely to violate its fiduciary duties under applicable laws. St. Martin is required to provide Home with notice of such determination within three business days after making such determination.

Additionally, prior to the approval of the merger agreement by St. Martin’s shareholders, upon the determination by St. Martin’s board of directors that an unsolicited acquisition proposal constitutes a superior proposal compared to the transactions contemplated by the merger agreement, the board of directors of St. Martin may change its recommendation in favor of the merger agreement (but not terminate the merger agreement) if, prior to changing its recommendation, (1) St. Martin’s board of directors determines, in good faith, after consultation with its outside legal and financial advisors, that failure to change its recommendation would be reasonably likely to be inconsistent with its fiduciary duties to St. Martin’s shareholders, (2) St. Martin provides Home with notice that St. Martin’s board of directors intends to or may change its recommendation and provides an opportunity for Home to make an improved proposal, and (3) St. Martin’s board of directors determines, in good faith, after consultation with its outside legal and financial advisors, that the acquisition proposal constitutes a superior proposal compared to any such improved proposal by Home. However, St. Martin may terminate the merger agreement in such circumstances if it makes a determination to accept the superior proposal.

Unless the merger agreement is terminated before the St. Martin special meeting, St. Martin is required to submit the merger agreement to its shareholders.

Conditions That Must Be Satisfied or Waived for the Merger to Occur (page     )

Currently, Home and St. Martin expect to complete the merger in the fourth quarter of 2017 or the first quarter of 2018. As more fully described elsewhere in this joint proxy statement/prospectus and in the merger agreement, the completion of the merger depends on a number of conditions being satisfied or, where legally permissible, waived. These conditions include, among others:

We cannot be certain when, or if, the conditions to the merger will be satisfied or waived, or that the merger will be completed.

The merger agreement can be terminated at any time prior to completion by mutual consent, if authorized by each of the Home and St. Martin boards of directors, or by either party individually, in the following circumstances:

In addition, Home may terminate the merger agreement if St. Martin has received a “superior proposal” and St. Martin’s board of directors has (1) entered into an acquisition agreement with respect to the superior proposal or (2) withdrawn its recommendation regarding the merger, failed to make its recommendation or modified or qualified its recommendation in a manner adverse to Home. Home also may terminate the merger agreement if St. Martin fails to substantially comply with its obligations with respect to consideration and action upon alternative acquisition proposals.

St. Martin also may terminate the merger agreement if St. Martin has received an acquisition proposal that St. Martin’s board of directors determines to be a “superior proposal” and St. Martin’s board of directors has made a determination to accept such superior proposal.

If the merger agreement is terminated, it will become void, and there will be no liability on the part of Home or St. Martin, except that (1) in the event of willful breach of the merger agreement, the breaching party will remain liable for any damages, costs and expenses, including without limitation, reasonable attorneys’ fees incurred by the non-breaching party in connection with the enforcement of its rights under the merger agreement, (2) designated provisions of the merger agreement, including the payment of fees and expenses and the confidential treatment of information, will survive the termination and (3) under certain circumstances, a termination of the merger agreement will obligate St. Martin to pay Home a termination fee.

Termination Fee (page     )

St. Martin will be obligated to pay Home a termination fee of $3,500,000 under the following circumstances:

Each of Home and St. Martin has agreed to cooperate with the other and use all reasonable efforts to obtain all regulatory approvals and authorizations required to complete the transactions contemplated by the merger agreement, including the merger and the bank merger. In order for the merger to be completed, we must receive approval from the Office of the Comptroller of the Currency (which we refer to as the “OCC”), file a notice with the Louisiana Office of Financial Institutions (which we refer to as the “OFI”) and receive the non-objection of the Board of Governors of the Federal Reserve System (which we refer to as the “Federal Reserve Board”). Home and St. Martin have completed, or will complete, the filing of applications and notifications to obtain the required regulatory approvals. Although Home and St. Martin do not know of any reason why these regulatory approvals cannot be obtained in a timely manner, Home and St. Martin cannot be certain when or if they will be obtained.

The rights of St. Martin shareholders will change as a result of the merger due to differences in Home’s and St. Martin’s governing documents. The rights of St. Martin shareholders are governed by Louisiana law and by the St. Martin articles of incorporation and bylaws. Upon the completion of the merger, St. Martin shareholders will become shareholders of Home, as the continuing legal entity in the merger, and the rights of St. Martin shareholders will therefore be governed by Home’s articles and bylaws (but will continue to be governed by Louisiana law).

COMPARATIVE HISTORICAL AND PRO FORMA PER SHARE DATA

Presented below for Home and St. Martin are comparative historical and unaudited pro forma equivalent per share financial data as of and for the year ended December 31, 2016, and as of and for the six months ended June 30, 2017. The information in the table is based on, and should be read together with, the historical financial information that Home has presented in its filings with the SEC and the historical financial information that St. Martin has presented in its financial statements included in this joint proxy statement/prospectus beginning at page F-1. See the section entitled “Where You Can Find More Information” beginning on page     .

The unaudited pro forma information gives effect to the merger as if the merger had been effective on December 31, 2016 or June 30, 2017 in the case of the book value data, and as if the merger had been effective as of January 1, 2017 or January 1, 2016 in the case of the earnings per share and the cash dividends data. The unaudited pro forma data combines the historical results of St. Martin into Home’s consolidated financial statements. While certain adjustments were made for the estimated impact of fair value adjustments and other acquisition-related activity, they are not necessarily indicative of what would have occurred had the acquisition taken place on January 1, 2017 or January 1, 2016.

The unaudited pro forma adjustments are based upon available information and certain assumptions that Home and St. Martin management believe are reasonable. The unaudited pro forma data, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the impact of factors that may result as a consequence of the merger or consider any potential impacts of current market conditions or the merger on revenues, expense efficiencies or asset dispositions, among other factors, nor the impact of possible business model changes. As a result, unaudited pro forma data are presented for illustrative purposes only and do not represent an attempt to predict or suggest future results. Upon completion of the merger, the operating results of St. Martin will be reflected in the consolidated financial statements of Home on a prospective basis.

The pro forma combined book value per share of Home is based upon the pro forma combined common shareholders’ equity for Home and St. Martin divided by the total pro forma common shares of the combined entity and reflects St. Martin shares at the exchange ratio of 9.2839.

The pro forma combined book value per share of Home is based upon the pro forma combined common shareholders’ equity for Home and St. Martin divided by the total pro forma common shares of the combined entity and reflects St. Martin shares at the exchange ratio of 9.2839.

SELECTED FINANCIAL AND OTHER DATA OF HOME

The following summary presents selected consolidated financial data of Home as of and for the periods indicated. The financial data as of and for the years ended December 31, 2016, 2015, 2014, 2013 and 2012 has been derived from Home’s audited financial statements contained in Annual Reports on Form 10-K that Home has previously filed with the SEC. The financial data as of and for the six months ended June 30, 2017 and 2016 has been derived from Home’s unaudited consolidated financial statements contained in Quarterly Reports on Form 10-Q that Home has previously filed with the SEC. The information as of and for the six months ended June 30, 2017 and 2016 is unaudited and reflects only normal recurring adjustments that are, in the opinion of Home’s management, necessary for a fair presentation of the result for the interim periods presented. The results of operations for the six months ended June 30, 2017 are not necessarily indicative of the results to be achieved by Home for all of fiscal 2017 or for any other period.

SELECTED FINANCIAL AND OTHER DATA OF ST. MARTIN

The following tables set forth certain summary historical consolidated financial information of St. Martin for each of the periods indicated. The historical financial information as of and for the years ended December 31, 2016 and 2015, except for the selected ratios, is derived from the audited financial statements of St. Martin included elsewhere in this joint proxy statement/prospectus. The historical financial information as of and for the years ended December 31, 2014, 2013 and 2012, except for the selected ratios, is derived from the audited financial statements of St. Martin not included in this joint proxy statement/prospectus. The historical results of St. Martin may not be indicative of its future performance.

You should read the selected historical consolidated financial and operating data set forth below in conjunction with the sections titled “Information about St. Martin – Management’s Discussion and Analysis of Financial Condition and Results of Operations of St. Martin,” as well as the consolidated financial statements of St. Martin and the related notes included elsewhere in this joint proxy statement/prospectus.

UNAUDITED PRO FORMA COMBINED CONDENSED CONSOLIDATED FINANCIAL DATA

The Unaudited Pro Forma Combined Condensed Consolidated Financial Information has been prepared using the acquisition method of accounting, giving effect to the merger. The Unaudited Pro Forma Combined Condensed Consolidated Statement of Financial Condition combines the historical information of Home and St. Martin as of June 30, 2017 and assumes that the merger was completed on that date. The Unaudited Pro Forma Combined Condensed Consolidated Statements of Income combines the historical financial information of Home and St. Martin and give effect to the merger as if it had been completed as of the beginning of the periods presented. The Unaudited Pro Forma Combined Condensed Consolidated Financial Information is presented for illustrative purposes only and is not necessarily indicative of the results of income or financial condition had the merger been completed on the date described above, nor is it necessarily indicative of the results of income in future periods or the future financial condition and results of income of the combined entities. The financial information should be read in conjunction with the accompanying notes to the Unaudited Pro Forma Combined Condensed Consolidated Financial Information. Certain reclassifications have been made to St. Martin historical financial information in order to conform to Home’s presentation of financial information.

The proposed merger is targeted for completion in the fourth quarter of 2017 or first quarter of 2018. There can be no assurance that the merger will be completed as anticipated. For purposes of the Unaudited Pro Forma Combined Condensed Consolidated Financial Information, the fair value of Home’s common stock to be issued in connection with the merger was based on Home’s closing stock price of $42.52 as of June 30, 2017.

The Unaudited Pro Forma Combined Condensed Consolidated Financial Information includes estimated adjustments, including adjustments to record St. Martin’s assets and liabilities at their respective fair values, and represents Home’s pro forma estimates based on available fair value information as of the date of the merger agreement. In some cases, where noted, more recent information has been used to support estimated adjustments in the pro forma financial information.

The pro forma adjustments are subject to change depending on changes in interest rates and the components of assets and liabilities and as additional information becomes available and additional analyses are performed. The final allocation of the purchase price for the merger will be determined after it is completed and after completion of thorough analyses to determine the fair value of St. Martin’s tangible and identifiable intangible assets and liabilities as of the date the merger is completed. Increases or decreases in the estimated fair values of the net assets as compared with the information shown in the Unaudited Pro Forma Combined Condensed Consolidated Financial Information may change the amount of the purchase price allocated to goodwill and other assets and liabilities and may impact Home’s statement of income due to adjustments in yield and/or amortization of the adjusted assets or liabilities. Any changes to St. Martin’s stockholders’ equity, including results of operations from June 30, 2017 through the date the merger is completed, will also change the purchase price allocation, which may include the recording of a lower or higher amount of goodwill. The final adjustments may be materially different from the unaudited pro forma adjustments presented herein.

We anticipate that the merger will provide the combined company with financial benefits that include reduced operating expenses. The Unaudited Pro Forma Combined Condensed Consolidated Financial Information, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the benefits of expected cost savings or opportunities to earn additional revenue and, accordingly, does not attempt to predict or suggest future results. It also does not necessarily reflect what the historical results of the combined company would have been had Home and St. Martin been combined during these periods.

The Unaudited Pro Forma Combined Condensed Consolidated Financial Information has been derived from and should be read in conjunction with the historical consolidated financial statements and the related notes of Home, incorporated herein by reference and those of St. Martin, which appear elsewhere in this document.
